Contingent Ethnicity in State(s) of Change: The Journey of
Meskhetian Turks from the USSR to the Post-Soviet World.

▼ In this dissertation, I examine issues of ethnic
engineering, interethnic tensions and social problems through a
story of Meskhetian Turks, a group that was subjected to a forced
deportation during the Soviet period, suffered from interethnic
violence in Fergana valley in 1989, and had been persistently
denied Russian citizenship through the 90s. Anthropologically
informed analysis of the history of this group illuminates the
effects of the state on specifics of everyday life during the
Soviet and post-Soviet periods. Thus, the story of Meskhetian Turks
is at the same time the story of the Soviet and post-Soviet state
and offers a perspective on governance in Russia as a culturally
and historically specific project. By creating a historically
informed account of social processes that contributed to the
formation of Meskhetian Turks as a group, I make three broad
arguments:1) Processes of change taking place in Russia during the
last decade of the 20th century were not chaotic or haphazard but
were contingent on practices and attitudes that emerged during the
Soviet period.2) Through memories of belonging people make sense of
the changing world around them. In the post-Soviet world, they
domesticate grand history explicating the political and preserving
the private thereby preserving memories of the "Soviet". 2.1) A
corollary to the first two points is that the state and its
subjects mutually legitimate each other.3. The state's control over
its people(s) is not absolute. Overview of Meskhetian Turks'
history shows gaps in the state's management (imperfect taxonomies
of ethnicity, loosening grip on
migration, citizens' withdrawal
into the sphere of kinship and domesticity) that fuel further
change. Thus, while the state influences people's lives at the
micro-level of the family and the household, its effects cannot be
seen as determined entirely by the policy.Conclusions drawn from
the story of the Meskhetian Turks can be extended to other groups
as well and help one better understand complexities of societal
changes that affected many other ethnic groups in the Soviet Union
and beyond.

Gender Differences in Migration, Marital Timing, and Spousal

▼ This dissertation uses a life course perspective to
investigate
migration and marriage as separate and inter-related
life events. It explores the gendered nature of
migration and its
determinants, with a particular focus on disentangling
marriage-related mobility from premarital
migration of young women
in the South Asian cultural context. It examines the gender
differences in marital timing and decision-making about spousal
choice and links these differences to education, employment, and
gender norms. This dissertation connects
migration to marriage by
investigating the timing and sequencing of these two life events.
To do so, it uses complex monthly and yearly data from the Chitwan
Valley Family Study (CVFS) collected over a 12-year-period at the
individual and household level in Western Nepal and uses event
history methods. For men,
migration temporarily disrupts marriage
but increases likelihood of marriage upon return due to
accumulation of capital. For women, education is more important
than
migration in increasing prospects of marriage. Additionally,
education influences women’s general mobility but not premarital
migration. This indicates that marriage is an important mediator of
the relationship between education and
migration for women in this
context. The combined results of age at marriage, education, and
employment on young adults’ spousal choice show that young adults’
sole participation in choosing spouse is not necessarily an
expression of higher individual agency as often assumed. The
process of choosing spouse with joint discussion with parents
(regardless of who primarily introduced the spouse) is distinctly
different and preferred process than the process of making sole
decisions. While young women may use their educational achievement
as an incentive and a tool for discussing their spousal choice with
parents to settle on a mutually acceptable spouse who might support
her career aspirations, young men do so with their employment
prospects. It seems they are interested in legitimizing their
marriage through parents’ approval rather than alienating familial
support and perceive this as exercising their agency to achieve
their marital and career goals. Overall, these results indicate
that education and employment influence the process of
migration
and marriage differently for men and women.

Sheltered Lives: God, Sex, and Mobility in Nigeria's
Counter-Trafficking Programs.

▼ This dissertation is an ethnography of a
government-run residential center for migrant women identified as
human trafficking victims, based on 16 months of qualitative
fieldwork in and around Lagos, Nigeria, from 2008 to 2010. Over the
past 10 years, thousands of women have been intercepted as human
trafficking victims as they attempted to leave Nigeria. Most of
them had initiated their own travel but were stopped before ever
reaching their final destination. They were then transported to a
federal rehabilitation center to be held as their cases were
investigated. Nigerian officials have proudly described this form
of intervention as preemptive, having successfully captured the
women before any abuses had taken place. Yet most of the so-called
victims in these cases do not see their experiences in these terms
and adamantly protest their detention—insisting they were not being
trafficked and demanding to be released. This project explores what
is at stake in one such shelter, for the women detained there and
the state agents trying to help them. It describes a model of
rehabilitation that glossed the desire to migrate and willingness
to take on debt to do so as vulnerabilities that needed to be
fixed. By documenting the ensuing arguments over the reasons these
women were traveling, the purpose of their detention at the
shelter, and their plans for life after being released, it presents
an account of emigration politics and policies not usually
associated with migrant-sending states. In addition, it uses those
debates as a lens onto citizen-state encounters in Nigeria, arguing
that they reveal the ad hoc relationships of governance that are
forged in the absence of faith in a legitimate state. Ultimately,
this research traces how transnational feminist movements,
North-South geopolitics, and ambitious postcolonial governmental
projects take shape in the day to day encounters between young
migrant women and state actors ostensibly intervening on their
behalf, thereby challenging facile reductions of African
governments like Nigeria as failed and corrupt
states.

Gender Differences in Education and the Timing of Migration

▼ The relationship between education and
migration has
been consistent across many cultures and societies; the more
education one has, the more likely one is to move. This
relationship provides evidence for the human capital of
migration
theory, which posits that individuals act rationally by moving if
they determine that there will be a positive net income return for
them eventually. The theory is criticized for not considering
familial reasons for moving and not addressing how gender norms and
expectations impact a man's decision to migrate versus a woman's.
However, the criticism does not help sociologists and demographers
understand the gender differences in the relationship between
socioeconomic fulfillment and the timing of
migration after one has
completed education. If educated individuals are very likely to
move after education completion, does the timing of this move
affect their long-term socioeconomic status? When do people move
relative to the completion of their education? Do educated women
face delayed
migration? And if so, does the delay significantly
hinder their social and economic development compared to men? Using
individual life history calendars from the 2002 and 2004 Population
and Environment Surveys of Central Region, Ghana, I conduct
discrete-time event history analysis to answer these questions. I
find that individuals who move soon after education completion have
higher socioeconomic status compared to those who delayed such a
move. There is no evidence to suggest that there is a difference
between how a delay in
migration after education completion affects
educated men and women. The results make a contribution by
suggesting that understanding the timing of moves can help us
understand different socioeconomic outcomes for people who have
ever moved. Collecting data more focused on economic outcomes would
be constructive for additional analyses to assess whether the
timing of such a move impacts men and women differently
socioeconomically.

▼ This dissertation is composed of three essays in
development economics. The first investigates the effect of rural
economic growth brought about by
migration and remittances on
Nepal's Himalayan forests. A unique village-panel data set
combining remote sensing data on land use and forest cover change
with multiple rounds of living standards survey is assembled to
test various inter-relationships between population, economic
growth and forest cover. Our results suggest that rural economic
growth spurred by remittances has had a positive impact on forests.
Although remittances also have a significant effect on local wages
and land prices, the primary channel through which it seems to
affect forests is through income.
The second essay examines the income elasticity of
micronutrients and their changes during periods of sharp increase
in food prices using data from two household surveys in Indonesia
conducted before (1996) and after (1999) the Asian financial
crisis. The primary finding is that the income elasticity of some
key micronutrients, such as iron, calcium and vitamin B1 are
significantly higher in a crisis year than in a normal year while
those for for some others – such as vitamin C – remain close to
zero. These results suggest that cash transfer programs might be
even more effective during crises to ensure the consumption of
essential micronutrients.
The third essay investigates the relationship between
rainfall shocks and child health using three most recent rounds of
Demographic and Health Surveys in Nepal. Precipitation data from an
expansive network of stations is used to interpolate rainfall in
each survey cluster using exact geo-coordinates. The findings
reveal that rainfall shocks have robust impact on child health in
the short run. Particularly, point estimates suggest that 10%
deviation in a completed monsoon rainfall from its long-term
historical normal causes a 0.17 standard deviation change in
weight-for-height, or 21% of the median weight-for-height in our
sample. Finally, the short run impacts do not seem to transmit to
the medium or long term, suggesting the possibility that children
catch up by the time they turn three.

▼ This dissertation's three essays explore the determinants of food insecurity for rural farm households, the influence of rainfall variability and long-run changes in rainfall levels on the
migration decisions of working-age household heads, and the distributional impacts in core and periphery regions of food assistance to households in the hinterland.
The first essay examines how socio-economic characteristics of households, local conditions, and public programs are associated with the probability that a farm household in rural Malawi is food insecure. The statistical analysis uses nationally representative data for 7,965 randomly-selected households interviewed during 2004/05 for the second Malawi Integrated Household Survey (IHS-2). Regressions are estimated separately for households in the north, center, and south of Malawi to account for spatial heterogeneity. Results of a Probit regression model reveal that households are less likely to be food insecure if they have more cultivated land per capita, receive agricultural field assistance, reside in a community with an irrigation scheme, and are headed by an individual with a high school degree. Factors that positively correlate with a household's food insecurity are number of household members and distance to markets.
The second essay uses nationally representative data from Malawi's 2004/05 Integrated Household Survey (IHS-2) to examine whether rainfall conditions influence a rural worker’s decision to make a long-term move to an urban or another rural area. Results of a Full Information Maximum Likelihood regression model reveal that (1) rainfall shocks constrain
migration, most likely by making it difficult for prospective migrants to cover costs of
migration, (2) migrants choose to move to communities where rainfall variability is lower, and (3) rainfall shocks have larger negative effects on the earnings of recent migrants than on long-time residents’ earnings.
The third essay examines how benefits from food assistance programs to needy households spillover between areas and among household income groups in the United States. We study the effect of the Supplemental Nutrition Assistance Program (SNAP) in the Portland Oregon metro Core and its Periphery trade area, using a Multiregional Input- Output (MRIO) model based on a Social Accounting Matrix (SAM). The analysis captures direct, indirect and induced effects of SNAP on each region and spillover effects on the other region. SNAP benefits to the lower income household classes in each region are traced to their effects on the local economy in each region, and to the effects on household income by income class. The analysis finds that (1) the economic impact on the Portland Core from a given level of SNAP benefits to households in the Periphery is greater than the economic impact in the Periphery from the same level of SNAP benefits to households in the Core; (2) high-income households benefit more than low-income households from the indirect and induced economic impact of SNAP.

▼ Les innovations récentes concernant les matériaux reposent beaucoup sur l’ajout et le contrôle d’interfaces. Cela est vrai pour les matériaux cristallins massifs incontournables pour les applications type structure, mais aussi pour les matériaux fonctionnels, micro-objets, ou les matériaux nanostructurés. Parmi ces interfaces il y a les joints de grains (JdGs) qui sont définis comme la frontière délimitant deux grains dont les orientations cristallographiques sont différentes. Les joints de grains contribuent fortement aux propriétés macroscopiques des matériaux. Le travail réalisé est une contribution à l’étude du comportement des joints lors de traitements thermomécaniques induisant leur mobilité. On parle de migration. En effet, Pour certains chargements thermo-mécaniques, les joints de grains (JdG) migrent dans les polycristaux métalliques. Malgré une littérature abondante sur le sujet, la compréhension du comportement collectif des dislocations et des JdG reste partielle au moins à l’échelle macroscopique. Ceci est dû, d’une part, au fait que plusieurs forces motrices sont actives simultanément dans les expériences sur polycristaux : (i) la tension de surface d’un joint courbé (ii) le différentiel d’énergie élastique pour les matériaux anisotrope élastiquement et (iii) enfin, la dernière force motrice est l’origine du couplage plasticité-migration. D'autre part, la mobilité des interfaces est intimement liée à leur structure atomique. Le présent travail se propose d’étudier théoriquement par simulation atomistique la migration en lien avec la structure des JdG. Des simulations de migration de JdG par dynamique Moléculaire, sous l’action d’une force motrice synthétique, sont réalisées. Une large variété de JdG, représentée par des bicristaux de Nickel, est étudiée. La mobilité des JdG est discutée en particulier pour différents plans du JdG et températures. A travers cette étude,trois caractères vis-à-vis de la température ont été observés : caractère thermoactivé, caractère athermique, et caractère antithermique. A ces caractères s’ajoutent d'autres comportements variant avec la température. Les simulations ont permis aussi l’identification de quelques mécanismes élémentaires de migration pour des JdG simples. Les JdG présentant une migration par formation de marche ou de disconnections ont été étudiés par la suite par la méthode Nudged Elastic Band. Cette méthode a permis de déterminer le chemin de minimum énergie lors de la migration. L’évolution du joint de grains lors de sa migration montre la nucléation et le déplacement des marches, identifiées comme des disconnections.
Recent innovations in materials rely heavily on the addition and control of interfaces.This is true for massive crystalline materials that are essential for structural applications, but also for functional materials, micro-objects, or nanostructured materials. Among these interfaces are the grain boundaries (GBs) which are defined as the boundary delimiting two grains with different crystallographic orientations.Grain boundaries strongly…

▼ Ce travail interroge les parcours de migration féminine précaire en tant que lieux d’expérience, de formation et de reconstruction de soi. Il s’intéresse aux dynamiques (trans)formatives de l’individu, auxquelles il associe l’émergence de postures de sujet et, plus précisément, d’un sujet culturel. Notre réflexion se situe dans le cadre d’une épistémologie centrée sur l’individu et ses espaces socioculturels et politiques d’action et de construction de soi. Nous avons donc fait appel à la recherche biographique en éducation, ainsi qu’à la perspective sociologique emmenée par l’Ecole de Chicago. La méthodologie qualitative de recueil et d’analyse des données s’y est inspirée et nous avons accordé la priorité à la parole singulière traduisant la migration en tant qu’expérience subjective. Cela nous a permis d’appréhender les parcours migratoires précaires en tant que projets de soi où le culturel participe à des processus de transformation du sujet, d’adaptation et d’apprentissage, mobilisés et organisés autour d’une revendication de pouvoir d’agir.
This work aims to study feminine precarious migration paths as places of experience, of learning and self reconstruction. It takes interest in individual transformation dynamics to which it associates the emergence of subjective postures and, more precisely, those of a cultural subject. Our intention relies on an epistemology focused on the individual and its socio-cultural and political spaces of action and self construction. We have thus chosen the biographical research in education as well as the sociological perspective of The Chicago School. They have brought on a qualitative methodology of data collection and analysis, helping us to focus on singular speeches, expressing migration as a subjective experience. Precarious migration paths thus appear as projects of self, where the cultural takes part in the subject’s process of transformation, adaptation and learning, mobilized and organized around a claim of power.

▼ Migration of labor out of rural areas in Mexico is an increasingly important feature of rural development in Mexico. New literature on
migration and development suggests that migrants play a role of financial intermediaries, making it possible for households to overcome credit constraints in their capability to attain the transition from small-scale, self-sufficient agriculture, to a market oriented production. The purpose of this research is to examine the impact of
migration on farm and non-farm income at a household level. Using a simultaneous equation model and data from a rural household survey from Mexico, I have tested the hypothesis that neither remittances nor
migration have an effect on farm and non-farm income. The econometric findings suggest that the loss of labor to
migration has a significant direct negative effect on non-farm income but the direct effect on farm income is not statistically significant. However, there is evidence that remittances have a significant positive effect on both income sources, so that
migration has an indirect effect that might compensate for the loss of labor.

▼ La moule bleue Mytilus edulis est un mollusque bivalve filtreur et sessile. Cet organisme présente un intérêt majeur d'une part en conchyliculture et d'autre part dans de nombreux programmes de surveillance environnementale comme espèce indicatrice du niveau de contamination par les xénobiotiques. Ce manuscrit propose une revue de la compréhension actuelle des mécanismes de l'immunité exclusivement innée des invertébrés, en s'attachant plus particulièrement au rôle prévalent des cellules immunocompétentes chez Mytilus : les hémocytes. Nos résultats permettent de proposer une classification des sous-populations hémocytaires de Mytilus edulis. A partir de colorations cytologiques classiques combinées à la cytométrie en flux et au volume Coulter ainsi que d'une caractérisation originale des motilités cellulaires par videomicroscopie d'intervalle (time-lapse), nos résultats proposent une description des activités et des interactions d'au moins trois sous-populations hémocytaires : les basophiles, les hyalinocytes et les granulocytes éosinophiles. La vitesse de migration des hémocytes a été mesurée in vitro par une nouvelle méthode, le tracking des noyaux. Cette approche permet de quantifier les activités migratoires de ces cellules ainsi que leurs perturbations, notamment par les stress environnementaux. Le second axe développé consiste en une analyse du phénotype de Multi Xenobiotic Resistance (MXR) au sein des sous-populations hémocytaires. Ce travail indique également que les transporteurs ABCC/MR Prégulent la motilité des cellules, ce qui ouvre des perspectives importantes.
Mytilus edulis is a bivalve mollusk and sessile filter feeder. This organism has a major advantage, both in aquaculture and in many environmental monitoring programs as an indicator species of the level of contamination by xenobiotics. This manuscript provides a review of the current understanding of the mechanisms of innate immunity exclusively invertebrates, focusing particularly prevalent role of immunocompetent cells in M. edulis : hemocytes . Our results allow us to propose an hemocyte subpopulations classification. By conventional cytological staining, flow cytometry equipped with a Coulter volume and characterization of cell motilities by videomicroscopy (time-lapse), our results provide a description of the activities and interactions at least three hemocyte subpopulations: basophils, and eosinophils hyalinocytes . The rate of of hemocytes migration was measured in vitro by a new method, the tracking of nuclei in time-lapse. This approach allows quantifying the migratory activity of these cells and their perturbations, including environmental stress. The second axis consists of an analysis of the phenotype Multi Xenobiotic Resistance (MXR) in the hemocyte subpopulations. This work also indicates that carriers ABCC / MRP regulate cell motility, which opens important perspectives in terms of biology immunity and evaluation of the immunocompetence of these animals.

Coming and Going: A Narrative Inquiry into Women's Stories

▼ Narrative inquiry provides a methodological framework
and philosophy to guide the research process, as well as directs
the methods that may be used (Clandinin & Connelly, 2000).
The purpose of this narrative inquiry research was to increase both
understanding and awareness of the experiences of four women who
were left behind while their partners engaged in temporary labor
migration in another Canadian province. The following questions
framed this inquiry and were used to elicit stories reflective of
the women’s experiences. 1. What stories are women telling about
themselves during the experience of being left behind as their
partner leaves home for employment in another province? 2. What
stories are women constructing in regards to who they are and who
they are becoming as they experience a partner’s employment
outmigration? Do they include in these stories how they think this
is changing other women’s views of themselves? 3. What stories are
women constructing regarding their perceptions of health and how
they perceive their personal health to be impacted as a result of
their husband’s coming and going for employment outmigration? In
review of literature, policy, and position statements, I have
learned of the emphasis placed on economic development and labor
market trends within the Atlantic Region. However, temporary labor
migration and the experiences of those left behind have been
overlooked. Further lacking is an understanding on how this
phenomenon impacts those who are left behind, particularly women
who remain behind and care for children. Digitally recorded
conversational interviews and photographs provided glimpses into
the stories lived, told, relived, and retold by women who were left
behind in rural communities and experiencing a partner’s temporary
interprovincial labor migration. Women recruited for this inquiry
co-participated in 5 or 6 conversational interviews. Each
co-participant had experienced the coming and going of their
husbands for employment out of province for between 6 and 12 years.
Conversational interviews lasted between 1 and 2½ hours. All
interviews were digitally recorded and transcribed verbatim. To
gain a deeper understanding of how women experience the coming and
going of their husbands due to labor migration, the participants
were invited to share personal photographs. These photographs
offered a visual representation of the women’s storied lives.
Analysis of data occurred through an interpretive process of moving
back and forth between field texts, interim research texts, and
research texts shaped by questions of meaning and social
significance. In shaping field texts into research texts, nine
overarching narrative threads emerged and revealed the women’s
perceptions regarding identity: who they were, who they were
becoming, and how they thought they were perceived by others as
they experienced their husband’s inter-provincial labor migration.
These narrative threads were organized under the headings:
Being—The Married Single Mother, Fulfilling Roles and
Responsibilities,…

▼ Many species of birds migrate nocturnally. In nocturnally migrating birds, endogenous
circadian and circannual rhythms serve as biological pacemakers (clocks). They are responsible
for an individual’s migratory behavioral pattern (Zugunruhe). Circannual rhythms
provide the major basis for the initiation of migratory restlessness both in autumn and
spring. Circadian rhythms on the other hand, play an important role in regulating the increase
of nocturnal activity that is necessary for flying long distances. The significance
of these endogenous factors is evident in migrating birds in the sense that, zugunruhe
keeps happening even in the absence of external inputs. Plasma melatonin concentration
is crucial to this phenomenon. Melatonin concentrations in most migratory birds increase
at night regardless of whether individuals are day or night active. In the course of migratory
seasons, many birds show restlessness and excessive activity during night. In migratory
populations, night level of melatonin is lower during the migratory period, when birds show
nocturnal restlessness, than before and after this period, when birds do not show nocturnal
activity. The operation of this endocrine system of oscillators is far too complex to
understand by intuition so we unavoidably have to resort to abstractions. Mathematical
models are therefore essential in understanding the mechanism of the components of this
system and to further determine the dynamics of these periodic oscillators. Scheper model
is a set of delay differential equations which describes the circadian clock. This model is
based on the total duration of the chain reactions and the nonlinearity between input and
delayed output of the protein synthesis negative feedback loop. In this study, two systems
of scheper equations were coupled to produced circannual oscillation depicting the seasonal
change in the melatonin level of nocturnally migratory birds. The coupled system
displayed realistic behavior of circannual rhythm with respect to period and entrainment.

▼ This body of research uses numerical models to
investigate the dynamics of melt generation in the asthenosphere,
accumulation at the base of the lithosphere by porous flow and
subsequent infiltration into the lithosphere by dike propagation.
Chapter 1 uses numerical models of melt
migration in a viscously
compacting matrix together with synthetic receiver function to show
that the onset of melting in the asthenosphere can produce a
seismic velocity gradient capable of generating a converted phase.
To explain observed phases attributed to melting onset in regions
with significant water in the mantle source, either (1) water is
entrained as an initially dry plume passes through a hydrated
transition zone or (2) the dependence of seismic velocity on melt
fraction is much stronger than the standard relationship used in
this study. Chapter 2 formulates a model for dike propagation from
a partially molten boundary layer at the base of the lithosphere.
Dikes propagate a short height into the lithosphere before freezing
and a quasi-steady state boundary layer of high melt fraction can
persist at the base of the lithosphere above regions of melt
production. Chapter 3 investigates how melt intruding at the base
of the lithosphere may influence the thermal and mechanical
evolution of the lithosphere. Basal heating of the lithosphere by
intruding dikes can rapidly thin the lithosphere on the order of
tens of km/Myr, concentrating stress and triggering extension in
the remaining lithosphere with little to no evidence of magmatic
influence. The predicted time between extension onset and mantle
lithosphere erosion matches the observed time over which strain
accommodation in rift basins transfers from extension along border
faults to magmatic accommodation. The calculated 2-D melt
distributions seems consistent with the hypothesis that the
negative velocity gradient observed near the base of the
lithosphere in volcanic and extensional regions is caused by melt
accumulating at its solidus.

▼ The first two chapters in this dissertation contribute
to the understanding of the relationship between location decisions
and city attributes. The last chapter explores the fundamental
explanations for housing price appreciation.
Chapter 1 investigates how the location decision on labor
market entry affects a worker’s wage growth. I find that wage
growth is more rapid in larger, denser and more highly educated
cities. Furthermore, an individual’s learning ability, which is
presumably associated with social skills as well as cognitive
aptitudes, begets further learning in big cities. Estimates imply
that in addition to the city-size wage level premium of 15.2
percent, college graduates who entered the labor force in big
cities experienced 7.2 percent higher wage growth over the
five-year period immediately following labor force entry than their
counterparts in small cities. Positive sorting by learning ability
adds another 3.1 percent to the wage growth gap between big and
small cities.
Chapter 2 extends the intercity
migration decision to the
later stages of people’s life cycles and proposes a new explanation
for falling internal mobility in the U.S. since the 1980s.
Following the method in Chapter 1, I measure the evolution of wage
growth differentials of American cities over time using the 1980,
1990 and 2000 censuses. By pooling individual-level data from the
three censuses, I show that the increase in wage growth gain in
relatively large cities has induced people in 1990 and 2000 to stay
in these more populated locations longer than their 1980
counterparts.
Chapter 3 proposes an empirical approach using both city
level and residential development project level data to evaluate
the role of changes in fundamental factors in driving rising
housing prices in the 2000s across major housing markets in China.
I find that while for most of the cities in my sample, actual
housing price appreciation can be largely explained by changes in
fundamental factors, seven cities seem to have “overly high”
housing price appreciation rates.

The Effects of International Migration on the Educational

▼ Studies on the socioeconomic impact of U.S.
migration
in Mexico often focus on the investment of remittances in household
assets and property. Little attention is given to its impact on the
education of the children of migrants in Mexico. This dissertation
analyzes the role of U.S.
migration and remittances on the school
and work status, educational attainment, and intergenerational
educational mobility of Mexican youth using the 10% sample of the
2000 Mexican Census. Results are consistent with the existence of
two processes connecting international
migration and education in
Mexico. The first process is the positive effect of family
investments in education through remittances and
migration income.
This effect, however, diminishes at older ages and at higher levels
of schooling as young people break away from parental influence and
gain agency to make educational choices. The second process is the
peer effect o living n a community with high levels of
migration,
in these communities, high
migration prevalence has a
countervailing effect on youth�s education and encourages
discontinuation of schooling, as youth becomes oriented to the U.S.
labor market. The results of this study call for the development of
more comprehensive conceptual frameworks to understand the impact
of
migration on the outcomes of youth. In addition, this research
also has implications for the use of
migration prevalence as an
instrument for measuring
migration at the household level. Although
it is clear that the prevalence of
migration in the community is
correlated with the probability of household
migration, it also
embodies a social context within which
migration is normative. This
means that from an aspirational perspective,
migration prevalence
in the community has an impact on education opposite that of family
investments. Therefore, instrumenting family
migration with
community level prevalence may lead to incorrect inferences with
regard to the impact of
migration experience on educational
attainment. This dissertation provides important insight to the
relationship between international
migration and investments on
education for younger members of the family. It also has important
implications for the understanding of the interaction between
family characteristics and the local economic
context.

▼ My dissertation uses the lens of
migration to examine
the relationship between mobility and migrant social networks for
the black population of South Africa. It specifically examines the
change in overall, intra- and inter-provincial, and rural-urban
migration patterns, determinants, social networks, and remittances
for black South Africans from the apartheid era (up to 1993) to the
post-apartheid era (after 1994). I examine
migration patterns,
social network strength, and remittance behavior through the use of
four cross-cutting themes: historical change, gender, location, and
types of
migration, including forced
migration, family
migration,
and solo
migration. My research uses multivariate event history
analysis of nationally representative survey data to examine the
patterns and demographic, economic, political, and social
determinants?including social networks?of black internal
migration.
I find robust evidence that voluntary internal
migration increased
among black South Africans over the last half of the twentieth
century, and that this increase began well before the official end
of apartheid. Yet I also find that the strength of social networks
for black South African migrants has decreased over time, and that
only 30 percent of migrants send remittances to their families
(although this percentage has increased slightly over the period
under study). These findings suggest that although migratory agency
persevered, even in the face of apartheid's strictures, apartheid
(and its legacy) has had a persistent negative effect on black
migrants' social networks and their ability to remit money to their
families.

ASSESSMENT OF THE MAGNITUDE, PATTERNS AND DETERMINANT FACTORS OF HEALTH WORKER MIGRATION FROM THE PUBLIC HEALTH SECTORS: A descriptive case study in East Hararghe zone of Oromiya, Eastern Ethiopia.

▼ Background: Human resources for health have become a topical issue at local, regional and
global levels. Addressing the current state of human resources crisis in health system is crucial
because the situation of the health workforce has become a critical challenge for sub-Saharan
Africa. It is suggested that without renewed emphasis on the health workforce crisis, it will be hard
for African countries like Ethiopia to attain the health-related Millennium Development Goals by
2015.
Objective: The main objective of study was to assess the magnitude and patterns of health
workers
migration and to explore the potential factors leading to the attrition of health workers from
the public health sectors in East Hararghe of Oromiya, Eastern Ethiopia.
Methodology: A descriptive case study was used as study design and a mix of quantitative and
qualitative method of data collection with appropriate procedures was employed.
Results: A total of 205 different professional categories of health workers included in the study.
Out of 168 health workers responded to the questionnaire, 83.9 % said that on average 4-8 health
workers from each professional category leave the public health sectors each year. The reviewed
documents showed that turnover rate in 1999 E.C were 66.7% for Physicians and 36.8% for
nurses. About three-quarter (76.2%) of respondents were not happy with their management, more
than half 51.8 % reported poor management and leadership were the main reason for health
workers
migration from public health sectors and almost all of focus group discussants strongly
agreed that their management were lacked common management and leadership skills like
motivation, supervision and communication. While, about 35% of the health workers indicated that
insufficient salaries and incentives to cover basic needs are a major reason for health workers
attrition. The majorities (63.1%) of study participants were not satisfied by their salaries and
incentives. The respondents also revealed that high work stress, favoritism, shortages of essential
equipments and absence of specific human resource policy were also contributing to the health
workforce crisis. The group discussant cited that the
migration had great effect on health care
delivery, other health professional and economic development of the country.
Conclusion: The study showed that there was high rate of
migration of health workers in the zonal
health system. Poor management skills at different levels of zonal health system were reported as
causes of health workers
migration by majority of study participants. Low salaries and incentives
among the financial factors were also identified as push factors leading to
migration. Political and
policy gaps also contributed to the problem. In general,
migration threatens the functioning of the
health system by reducing service provision and creating inefficient use of resources leading to a
serious threat to the development of the country.

▼ The aim of this study is to assess the causes and impacts of child out
migration both on the lives
of the migrants and their parents, the extent to which the child out
migration affected the socioeconomic
activities of the sending community, and challenges and coping mechanisms of the
parents and the migrants. The study uses the DFID livelihoods framework and different
migration theories for analysis. The study employed sample survey in order to collect
information on socio-demographic characteristics, infrastructural, socio-cultural and economic
factors behind the child out
migration, and the positive and negative impacts on parents and
migrants livelihoods. The survey data were coded and entered into the computer for the
statistical analysis using the software Statistical Package for Social Sciences (SPSS) version 20.
Moreover, focus group discussion in both rural kebeles was conducted with parents and
community elders about the trend and
migration decisions of the children. In addition, in-depth
and key informant interview was held with community elders, woreda and kebele officials.
The study findings indicate that infrastructural limitations contributed their part on the child out
migration and economic problems (poverty) in place of origin and the better economic
opportunities at the destination are the major factors behind
migration which goes in line with
Ravenstein’s, Lee’s and cumulative and circular causation theories of
migration.
Migration as a
livelihood strategy has both positive impact like remittance and asset development and negative
impact like creating dependency and rural poverty.
The study also finds out poverty as a root cause for and consequence of child out
migration in
the study area, since the decision of the children to migrate is influenced by poor living
conditions at home and the departure of the children resulted in weakened socio-economic
activity in the rural community. Consequently, the rural community lost its productive youth and
became unable to get rid of poverty as the migrants didn’t invest on increasing livelihood assets.

▼ This study critically interrogates factors affecting digital migration and its uptake in Nairobi. The
digital migration is meant to enrich consumer experience, and improve on the quantity and quality of
programmes. The digital transition in broadcasting is a global process involving the switch from
analogue to digital broadcasting signals. A number of countries have completed this transition. Most
are, however, still making the transition. Even though the International Telecommunications Unions
set 2015 as the deadline for digital migration, the Kenya government initially set its own as 2012. It is
yet to transit to transit to digital broadcasting two years later in 2014. It is thus abundantly clear that
the transition from analogue to digital in Kenya has experienced numerous challenges. Among the
challenges include the fact that few television consumers and understand the importance of digital
migration and are thus not convinced that they need to invest in digital equipment necessary for them
to enjoy the benefits of digitisaton, including clearer signals and quality programming. The fact that
many people live in poverty, and can hardly afford to migrate, has not helped government efforts to
effect the migration. Besides, media companies and TV channels are seemingly not yet ready for the
migration given that they have often blocked attempts to switch off the analogue signals. In essence,
this research concludes that notwithstanding the deadline, the activities to effect the migration and
promises for more and better quality programming, the country and its citizens are not yet ready for
digitisation

▼ Many young Ghanaians risk their lives to cross the Sahara-desert and the Mediterranean Sea to seek greener pastures in Europe. By so doing they expose themselves to this dangerous journey, and some even lose their lives. It is for this reason that this dissertation sought to ascertain the causes of and effort made by Ghana to curb irregular migration through the Sahara-desert and the Mediterranean Sea to Europe. The study is qualitative and relied on both primary and secondary data. The study used Czaika and De Haas’ conceptual framework designed in their “Effectiveness of Immigration Policies” to analyze the various interventions by Ghana to address the irregular migration from Ghana. The findings identified lack of information/misinformation, limited economic opportunities, strict visa application processes, poverty and lack of agricultural facilities as major causes of irregular migration in general and are also specific to Ghana. It was also found that Ghana in collaboration with some non-state actors primarily the International Organization for Migration uses sensitization and education as the main tool to curb irregular migration from the country. The study’s assessment of this measure couple with others indicates that sensitization and education, though an effective strategy, implementation has not resulted in the desired objective of substantially reducing irregular migration from Ghana to Europe through the trans-Saharan route. Addition, the study notes that a major challenge leading to the ineffectiveness of the measures adopted was the short-term approach as well as limited funding and discontinuity of the programs. The study, therefore, recommended the need for continuous sensitization programmes, provision of adequate agricultural facilities, provision of adequate funding to the Ghana Immigration Service, implementation of the National Migration Policy and formalization of migration for unskilled labour through bilateral and multilateral agreements.

▼ This thesis examines Tonga’s internal
migration between 2001 and 2011. Firstly, it provides an analysis of Tonga’s internal
migration during that period and secondly it establishes whether the ‘drift south’ of Tonga’s population that was found in the 1970s is still the dominant flow.
The Tonga Censuses of Population and Housing in 2006 and 2011 are the sources of data for the study. The analysis is presented in two parts: the spatial characteristics of Tonga’s internal
migration between 2001 and 2006 and between 2006 and 2011, and the demographic characteristics of migrants during the same two periods. The spatial analysis explores four patterns of
migration with reference to the major administrative divisions in Tonga: within and between districts, within and between divisions, rural-urban
migration, and
migration between the Northern islands and Tongatapu to the south (the ‘drift south’). Five demographic characteristics: - age and sex, marital status, education and qualifications, and occupation - are examined for migrants and non-migrants.
The analysis of internal
migration in this thesis is the first substantive assessment of internal
migration in Tonga for many years. There has been a much stronger focus on international
migration than internal
migration in the Pacific region over the past two decades. The findings from the study are important in the context of an on-going debate about the scale and pace of urbanisation in Pacific countries. The research finds that there has been considerable stability in the patterns of population movement between the different administrative units in Tonga and that while urbanisation of the population continues, some of the major demographic changes linked with internal
migration are occurring in rural Tongatapu.

▼ Natural selection, in its most basic form, is described as a process in which traits
increase or decrease in frequency depending on their fitness, and only the trait with
the highest fitness will remain in the population. Yet, populations rarely have a
single `optimal' trait. The way natural selection maintains this observed variation
within populations has been a keen focus of evolutionary biologists. In the following
chapters, I focus on how natural selection maintains a form of phenotypic
variation referred to as `partial
migration'. Partial
migration is the coexistence of
migratory and non-migratory phenotypes, and is found in a wide variety of taxa. I
found that some, but not all forms of density-dependent competition can lead to the
evolution and maintenance of partial
migration (i.e., partial
migration as an evolutionarily
stable strategy (ESS) and convergent stable strategy (CSS)). Whether
density-dependent competition allows for partial
migration as an ESS and a CSS
depends on how it influences the relative fitnesses of the phenotypes. If competition
changes the relative fitnesses in opposing directions, then it will allow for
partial
migration. If it affects the relative fitnesses in the same direction, it will
not. I then apply these results to a fish species of conservation and commercial
concern: Oncorhynchus mykiss, or steelhead and rainbow trout. I demonstrate
how female steelhead and rainbow trout competing separately for spawning habitat
can still be
subject to frequency-dependent selection and how this allows for
partial
migration. The frequency-dependent selection also results in strong feedbacks
between survival and reproduction, which produces a non-linear response in
the
migration propensity ESS and CSS. In practical terms, this means that conservation
or management actions may not affect the population as expected, and
measuring the propensity for
migration in wild populations is notoriously difficult.
To address this difficulty, I develop a method to measure the propensity for
migration
in wild populations that can be used to test the predicts I generated in the
two previous chapters. The method is called sex-ratio balancing and it relies on a
fundamental relationship between sex ratios and the propensity for
migration. Sex
ratios are much easier to measure than the propensity for
migration and the ease
of measurement makes this method valuable for studying many different partially
migratory taxa.

▼ Au cours de l’athérosclérose, l’invasion de la paroi vasculaire par les leucocytes conduit à l’inflammation de ce tissu et à l’établissement d’un stress oxydatif. Ce travail aborde les effets du stress oxydatif et les effets d’interactions potentielles entre un modèle de neutrophiles (?HL60) et des cellules endothéliales (HCAEC) ou musculaires lisses (HCSMC) de coronaires humaines sur les métalloprotéinases (MMPs) cellulaires et la mobilité des ?HL60. Au cours des passages, la lignée promyélocytaire HL60, différenciée en modèle de neutrophiles ?HL60, subit des variations d’expression et de production de MMP9 et de ses propriétés de mobilité. Les espèces réactives de l’oxygène (ERO) d’origine biochimique ou cellulaire ne modifient pas l’activité MMP2 ou MMP9 des HCAEC et HCSMC. Il n’y a pas modification des activités MMPs en coculture ?HL60/HCAEC mais stimulation de l’activité MMP9 en coculture ?HL60/HCSMC. Les HCSMC stimulent les capacités migratoires et favorisent la réponse invasive des ?HL60 au N-formyl-L-Méthionyl-L-Leucyl-L-Phénylalanine. Les enzymes antioxydantes ont peu d’effet sur la mobilité, stimulent expression et production de MMP9 des ?HL60 et semblent diminuer l’effet stimulant des HCSMC sur la production de MMP9 par ?HL60. Les HCSMC expriment et/ou sécrétent certains cytokines (IL8, IL6, IL1?, CCL2, CXCL12) impliquées dans l’athérosclérose. En conclusion, l’interaction ?HL60/HCSMC entraîne une augmentation de production de MMP9, modulée par les ERO, et une stimulation de mobilité des ?HL60. Les cytokines inflammatoires impliquées dans l’athérosclérose et exprimées par les HSCMC sont des acteurs potentiels dans la réponse sécrétoire et/ou migratoire des ?HL60.
During atherosclerosis leucocytes invade the vascular wall, inducing inflammation and production of oxidative stress by reactive oxygen species (ROS). We tested the effects of an oxidative stress and/or potential interactions between a neutrophil model (?HL60) and human coronary endothelial (HCAEC) or smooth muscle (HCSMC) cells, on ?HL60 mobility and production and activity of cellular metalloproteinases. Cell passaging of the promyelocytic HL60 cell line, differentiated by DMSO in a neutrophil model (?HL60), induces variations in cell mobility and production of MMP9. ROS from biochemical or cellular sources did not modify MMP2 or MMP9 activity in HCAEC or HCSMC. There is no modification of MMPs activities in ?HL60/HCAEC cocultures, but stimulation of ?HL60 MMP9 activity in ?HL60/HCSMC cocultures. Basal migration capacities and N-formyl-L-Methionyl-L-Leucyl-L-Phenylalanine -stimulated invasion abilities of ?HL60 increase in presence of HCSMC. Antioxidant enzymes barely change ?HL60 mobility, increase expression and production of ?HL60 MMP9 and seem to reduce the stimulating effect of HCSMC on ?HL60 MMP9 production. HCSMC also express and/or secrete some cytokines (IL8, IL6, IL1?, CCL2, CXCL12) implicated in atherosclerosis. In conclusion, interactions between ?HL60 and HCSMC induce an increase in MMP9 secretion, which is modulated by ROS, and…

▼ This doctoral thesis aims to reconstruct, analyse and
provide a historical contextualization of the TV broadcast “Un’ora
per voi”, which was intended to promote the integration of Italian
workers and their families in Switzerland, in the years between the
early 1960’s and the late 1980’s. Within the framework of the
research on the history of television, this thesis focuses on an
unexplored field, with a view to overcoming the unavoidable bias of
the jubilee publications of radio and TV broadcasting companies and
the encyclopaedism of the most recent TV histories. This
opportunity has been provided by the exceptionality of the
subject-matter analysed: a TV broadcast co-produced by the Italian
(RAI) and the Swiss (SSR-TSI) broadcasting companies, actually a
cross-border micro-programme which managed to gather Italian and
Swiss viewers in front of the TV, to get to know each other in
order to overcome the misunderstandings that led to an open social
tension peaking in the xenophobe initiatives that influenced the
history of Switzerland in the 60’s and 70’s. Through the history of
the programme “Un’ora per voi” (and indirectly of the Swiss Italian
Television, which took part in its production) it is possible to
investigate the internal and external background that enabled a TV
broadcasting company in its adolescent stage to develop
significantly the integration function that was, and still is, at
the core of its public service mandate.

▼ Les chenaux sont des structures sédimentaires clefs
dans le transport et le dépôt de sédiments depuis les continents
jusqu'aux planchers océaniques. Leurs dépôts perméables permettent
la circulation et le stockage de fluides. Comme illustré avec les
systèmes turbiditiques, le remplissage de ces chenaux est très
hétérogène. Son impact sur la connectivité des dépôts perméables
est amplifié par les variations d'organisation spatiale des
chenaux. Mais du fait de l'aspect lacunaire des données,
l'architecture de ces structures souterraines n'est que
partiellement connue. Dans ce cas, les simulations stochastiques
permettent d'estimer les ressources et les incertitudes associées.
De nombreuses méthodes ont été développées pour reproduire ces
environnements. Elles soulèvent deux questions capitales : comment
analyser et comparer la connectivité de simulations stochastiques ?
Comment améliorer la représentation de la connectivité dans les
simulations stochastiques de chenaux et réduire les incertitudes
? La première question nous a conduits à développer une
méthode pour comparer objectivement des réalisations en se
concentrant sur la connectivité. L'approche proposée s'appuie sur
les composantes connexes des simulations, sur lesquelles sont
calculés plusieurs indicateurs. Une représentation par
positionnement multidimensionnel (MDS) facilite la comparaison des
réalisations. Les observations faites grâce au MDS sont ensuite
validées par une carte de chaleur et les indicateurs. L'application
à un cas synthétique de complexes chenaux/levées montre les
différences de connectivité entre des méthodes et des valeurs de
paramètres différentes. En particulier, certaines méthodes sont
loin de reproduire des objets avec une forme de chenaux.
La seconde question amène deux principaux problèmes. Premièrement,
il apparaît difficile de conditionner des objets très allongés,
comme des chenaux, à des données de puits ou dérivées de données
sismiques. Nous nous appuyons sur une grammaire formelle, le
système de Lindenmayer, pour simuler stochastiquement des objets
chenaux conditionnés. Des règles de croissance prédéfinies
contrôlent la morphologie du chenal, de rectiligne à sinueuse.
Cette morphologie conditionne les données au fur et à mesure de son
développement grâce à des contraintes attractives ou répulsives.
Ces contraintes assurent le conditionnement tout en préservant au
mieux la morphologie. Deuxièmement, l'organisation spatiale des
chenaux apparaît peu contrôlable. Nous proposons de traiter ce
problème en intégrant les processus qui déterminent l'organisation
des chenaux. Un premier chenal est simulé avec un système de
Lindenmayer. Puis ce chenal migre à l'aide d'une simulation
gaussienne séquentielle ou d'une simulation multipoints. Cette
approche reproduit les relations complexes entre des chenaux
successifs sans s'appuyer sur des modèles physiques partiellement
validés et au paramétrage souvent contraignant.
L'application de ces travaux à des cas synthétiques démontre le
potentiel de ces approches. Elles ouvrent des…

▼ Cell
migration is an essential part of many processes including embryonic development, wound healing, and unwanted processes like metastasis. Further study of cell
migration is needed to help understand these processes. A cell model system (F9 cells) was used which analogously represented early mouse embryo development to investigate cell
migration during early development.
Cell
migration during development requires cell-ECM attachments called focal adhesions and interactions with other cells. Adherens junctions are the best known cell-cell adhesion. Previous research has shown that adherens junctions are present in F9-derived parietal endoderm cells. Another, more recently discovered, type of cell-cell attachment is with the Nectin-Afadin complex.
The Nectin-Afadin complex has been shown to be crucial in other model systems of cell
migration and in the formation of adherens junctions. The research presented in this thesis will look at the presence of the Nectin-Afadin complex in F9-derived parietal endoderm. The research will also examine the molecular function of the Nectin-Afadin complex and examine if this function is consistent with the function of the Nectin-Afadin complex in other model systems.

▼ This thesis sets out to explain a paradox: how is it that Romanian migrants voice a discourse of mutual avoidance and mistrust, when conationals' help underscores every level of their journeys? The argument proposed here is that, contrary to the dangerous naturalisation of Romanian suspicion under tropes of Balkanism, this sense of disunity is constructed everyday by a neoliberal configuration which transfers social security onto personal connections, but which precisely in doing so comes to turn connections into the idiom of voicing discontent. To illustrate this, the thesis draws upon a year of multi-sited fieldwork conducted with Romanian migrants in a North London neighbourhood, and in a Carpathian village. Situating their departure within a discussion of the country's tortuous post-socialist transition, I show how the sense that there was nothing left at home gave rise to the widely shared hope that anything was possible abroad. For many of those who left, however, hope was not a frictionless return to Europe, but a journey made possible only by Romanian acquaintances who were called upon, much like in the imaginary of socialist informal economies, to arrange housing, legal status, or work in the UK. It is at this intersection of hope and help, where the duty to care for others and the concern to engineer one's own mobility come to clash, that discontent also emerges. Focusing thus on the sociality of informal help which propels Romanian migrants' journeys, this thesis seeks to enrich the migration literature by reaffirming the figure of the migrant as a moral subject endowed at once with interest and affect. Looking at the formation of mistrust, another ambition of this project is to draw attention to the dangers of personalising mobility, in a political economic configuration where state-based social security is increasingly eroded.

▼ This thesis examines the everyday citizenship practices of Bolivian migrants in Chile, and the ways in which migrant organisations influence these practices. It contributes to a growing body of literature that comprehends citizenship as both formal and substantive and is interested in migrants' incorporation within these different spheres. It is also situated within the incipient scholarship on South-South migration, and is among the first qualitative studies to address Bolivian migration to Chile. Bolivians conform one of the larger groups in an increasing migration flow to Chile, and are thought to be one of the most vulnerable. To date, however, there has been little that analyses their experiences in depth. Working across space and scale, nine months of multi-sited ethnographic research aimed to begin to fill this knowledge gap. Throughout five sites in Chile and Bolivia, participant observation was undertaken with migrant organisations, at community events, and in migrants' homes. Additionally, semi-structured interviews were conducted with 60 migrant participants, and sixteen representatives of migrant organisations and the state. Empirically, the project indicates that many Bolivians in Chile endure multiple exclusions from citizenship. These occur transnationally and are caused by varied structural, but also agentic, factors. The intersectional approach taken underscores the social identities that make exclusions more likely. Nevertheless, through engaging in varied citizenship practices, often with support from organisations, migrants are able to achieve greater inclusion. Conceptually, the thesis develops the idea of overlapping, fluid transnational spaces of citizenship, which represent its legal, economic, social, and political dimensions. They are produced through interrelations between processes from above, individual practices from below, and actions of migrant organisations. Migrants may be inside and outside different spaces of citizenship simultaneously. Those who live a complex array of inclusions and exclusions experience uncertain citizenship, the other core concept advanced in this work.
