▼ Using ground-based observations, as well as reanalysis and Coupled Model Intercomparison Project Phase 5 (CMIP5) data, the long-term changes in precipitation and surface temperature are studied for the Northern Great Plains (NGP) region for the period of 1965-2005. Significant positive trends of ~1-2 °C/41 years in annual mean temperature are found across North Dakota and Minnesota. This study also suggests that the eastern part of the NGP region is wetter than the western part of the NGP, for the past 41 years. In addition, the spatial-temporal changes of precipitation and temperature of the region, as well as their linkages to Multivariate El-Niño-Southern Oscillation (ENSO) Index (MEI), are investigated through empirical orthogonal function (EOF) analysis using reanalysis and CMIP5 data. The NGP’s temperature field exhibits larger increasing trends in the winter season, while the largest variations in precipitation are found for the summer season. This study further indicates that MEI is positively correlated with winter temperature in North Dakota, and ENSO could also be associated with variations in summer precipitation of the NGP region.

▼ For infants, acquiring vocabulary for nouns is a dynamic, complex process that involves pairing an auditory token with a visual referent. This process is computationally complex because the acoustic information produced for a verbal production of any given noun varies considerably due to factors including the person who is speaking, speaking rate, and linguistic context. Likewise, visual referents are also variable in characteristics such as size, shape, material, and color. Research suggests that
variability in either the auditory or visual domains can facilitate early word learning. However, the role of simultaneous
variability in these domains on noun learning remains unexplored. Using a 9-week training study, we examined the effects of auditory and visual
variability on word learning and generalization in 12 children ages 16- to 23-months in order to collect pilot data for a larger-scale investigation. All children were taught 12 nouns and were randomly assigned to one of four training conditions: low visual and low auditory
variability, low visual and high auditory
variability, high visual and low auditory
variability, or high visual and high auditory
variability. High versus low auditory
variability was manipulated by presenting ten talkers versus one talker, respectively. High versus low visual
variability was manipulated by presenting variable, dissimilar exemplars versus highly similar exemplars, respectively. The results to date suggest that high levels of
variability in the visual domain facilitated learning of trained items but did not influence the ability to generalize that category to novel visual exemplars. Moreover, overall vocabulary development appeared to be facilitated by high
variability in the auditory domain. These findings provide promising pilot data for understanding how visual and auditory
variability influence word learning not only in the laboratory, but also in the real-world linguistic environment.

ecology Datum odbrane: 03.06.2013.
Istraživanje zooplanktona obuhvatilo je analizu
kvalitativnog i kvantitativnog sastava kao i određivanje vremenske
i prostorne distribucije zooplanktona, pojedinih grupa i njihovih
vrsta na području Bokokotorskog zaliva. Istraživanje je obavljeno
na tri lokaliteta u Kotorskom, dva u Tivatskom i jednom lokalitetu
u Hercegnovskom zalivu. Uzorci su sakupljeni planktonskom mrežom
promjera okaca 125μm, jednim potezom od dna do površine.
Uzorkovanje je vršeno sedmično, 15-dnevno i mjesečno, sa ciljem da
se objasni velika brzina promjene brojnosti i distribucije
zooplanktona u plitkim oblastima. Tokom 16-mjesečnog istraživanja
mezozooplanktona Bokokotorskog zaliva određen je 81 takson iz
ukupno 7 filuma. U Kotorskom zalivu je nađeno 69 taksona, u
Tivatskom 70, dok su u Hercegnovskom zalivu zabilježena 72 taksona.
Godišnja dinamika ukupne gustine na sva tri područja (Kotorski,
Tivatski i Hercegnovski zaliv) pokazala je povećanje u toplijem
dijelu godine. Uzrok visokih vrijednosti u ljetnjim mjesecima na
području Kotorskog zaliva bila je pojava protozoe Noctiluca
scintillans sa velikim gustinama populacije, kao i razvoj
kladocera. Razvoj kladocera bio je i razlog ljetnjeg maksimuma u
Tivatskom i Hercegnovskom zalivu, dok se zimski maksimum u
Hercegnovskom zalivu javio kao posljedica velike gustine populacija
kopepoda. Dominantna grupa zooplanktona bile su kopepode. Srednja
procentualna zastupljenost iznosila je 67% u Kotorskom, 73% u
Tivatskom i 81% u Hercegnovskom zalivu. Takosoni Oncaeidae i
Oithona nana su dominirali u sastavu kopepoda na svim lokalitetima
u istraživanom periodu. Maksimalnim gustinama kopepoda prethodile
su visoke vrijednosti gustine fitoplanktona. Pojava velike gustine
populacije ktenofore Bolinopsis vitrea u Kotorskom zalivu,
predstavlja prvi takav nalaz u južnom Jadranu, kao i prvu masovnu
pojavu ove vrste u Mediteranu. Visoka negativna korelacija između
B. vitrea i kopepoda potvrđuje činjenicu da su ktenofore vrlo bitni
predatori čija aktivnost za posljedicu može imati značajan uticaj
na zooplanktonske zajednice. VII Rezultati ovog istraživanja su
pokazali da je u obalnim područjima korišćenje planktonske mreže
promjera okaca 125 μm neophodno za dobijanje preciznijih
vrijednosti ukupnog zooplanktona, jer najveći udio predstavljaju
rani razvojni stadijumi malih kalanoida i ciklopoida koji prolaze
kroz mreže grubljeg tkanja. Velike varijacije vrijednosti u svim
sezonama, posebno kopepoda, sugerišu da je za bolje razumijevanje
procesa u ovako produktivnim sistemima potrebno uzimati uzorke
češće od jednom mjesečno. Istraživanja ukazuju i na to da brze
promjene hidrografskih i produkcijskih parametara u zatvorenom i
eutrofnom Bokokotorskom zalivu značajno utiču na gustine populacija
zooplanktona.

▼ Pain is a multidimensional experience that combines sensory, affective, and cognitive factors, causing its treatment to be extremely complicated and often ineffective. Mindfulness meditation has been shown to be an effective approach to decreasing pain. While these benefits have largely been seen over extensive, eight-week long training regimens, we have repeatedly shown that just three to four days of mindfulness meditation training can significantly reduce pain. Mindfulness-based analgesia after brief mental training is associated with

▼ Heart rate variability (HRV), a marker of autonomic dysfunction, decreases with age but few studies have examined HRV longitudinally. Further, studies have shown gestational age, birth weight and physical activity (PA) may influence a person’s HRV. The purpose of this study is to compare PA and HRV between 108 preterm/very low birth weight (PT/VLBW) participants and 20 full term/normal birth weight (FT/NBW) peers from adolescence and young adulthood. HRV was determined from a 5-minute resting ECG using Nevrokard Software. The root square mean of the standard deviation (RMSSD), high frequency (HF), and low frequency/high frequency (LF/HF) ratio were used to reflect HRV. Average total hours and vigorous hours per week for the past year were estimated from the Modifiable Activity Questionnaire. Repeated Measures ANOVA demonstrated no between group differences but significant within group differences indicating a decrease in HRV from adolescence to young adulthood (p<0.001). Mann-Whitney U tests found significantly lower vigorous PA at adolescence as well as total and vigorous PA at young adulthood (p<0.05) in PT/VLBW compared to their FT/NBW peers. However, no associations were evident for PA in adolescence or change in PA and change in HRV from adolescence to young adulthood.

▼ Information on genetic variability and stability of yield and yield components of sunflower in Zambia is lacking. The study was undertaken to determine the magnitude of yield; determine the relationships between yield and it's components; and estimate the heritability and stability of important traits in sunflower. Twenty five genotypes representing a random sample of the breeding populations in an on going sunflower improvement programme were grown in a 5 X 5 triple lattice design in 5 locations in the 1993/94 growing season. Data on kernel yield, kernel yield/head, oil content, oil yield, head diameter, stem diameter, plant population, plant height, average number of leaves/plant, number of days to 50% flowering, 1000 kernel weight and kernel % were collected and/or derived. The magnitude of yield was determined at harvesting. The relationship between yield and it's components was determined by path coefficient analysis. Presence of genetic variability was indicated by significant genetic variance. Heritability was estimated from variance components. Stability analysis was also done. The magnitude of kernel yield was found to be comparable with world averages though the average kernel yield of 1163 Kg/ha was below the country range of 1500 to 2000 Kg/ha) due to poor rains. High correlations between kernel yield and plant height (r = 0.420**), stem diameter (r = 0.589**) and kernel yield/head (r = 0.658**) were observed but their direct effects on kernel yield were very small (-0.216, -0.154 and -0.189 respectively). However, their indirect effects were more positive mostly through head diameter (0.127, 0.174 and 0.141 respectively). Head diameter showed large direct effects on both kernel yield (0.311) and oil content (0.581). The direct effect of 1000 kernel weight on oil yield (0.173) was large relative to overall correlation (r = 0.195**). The genetic variances for kernel yield, oil content, oil yield, head diameter, plant height, kernel yield/head and 1000 kernel weight were significant (P < 0.05). The broad sense heritability estimates for kernel yield ranged from 5.42% in Golden Valley to 33.01% in Monze; overall the estimate was 7.12%. For oil content the estimates ranged from 14.95%) in Mt Makulu to 52.35% in Monze with an overall estimate of 11.43%i. Similarly those of oil yield, plant height, stem diameter and 1000 kernel weight ranged from 8.36% in Golden Valley, 9.36% in Monze, 5.77% in Mt Makulu and 5.54% in Mt Makulu respectively to 26.78%) in Monze, 61.96%) in MRS, 27.27%o in Mt Makulu and 37.66%) in Monze respectively with the overall estimate being 20.37%, 10.20%), 0.23%), and 2.51% respectively. For head diameter the estimate was 17.33%) in Mt Makulu and 2.97% overall. Genotype X location interaction effects were significant for kernel yield, oil yield, 1000 kernel weight, stem diameter and plant height. Sunflower with respect to kernel and oil yield showed average ability to be consistent across locations. Overall the magnitude of yield was found to fall within an acceptable range with genetic…

▼ Previous research has provided evidence for the notion that there are varying levels of inconsistency between individuals when responding to questionnaires with multiple response items. Specifically, there are individual differences in how consistently persons respond to items from the same dimension in a questionnaire (Reddock, Biderman & Nguyen, 2011). Currently, there is not a consensus on how inconsistency should be measured. In the present study inconsistency of responses to the IPIP Big Five questionnaire was measured. Two response formats permitting measurement of inconsistency were compared - a frequency-based format (FB) vs. a traditional Likert scale format. Furthermore, in an effort to study inconsistency in a broader context, the relationships of social desirability and ADHD to inconsistency were examined. The results provided no evidence for convergent validity between the two measures, discriminant validity for each measure, no evidence of a relationship between BIDR and inconsistency, but a positive relationship between FB based inconsistency and scores on the ADHD measure. Implications and limitations of the study are discussed.

▼ Internal climate variability has been found to influence the climate response to an external forcing such as CO2. This thesis investigates the influence of the Atlantic Multidecadal Variability (AMV), a mode of internal climate variability in the North Atlantic Ocean, on the response to external forcing. The AMV is a 60 - 80 year fluctuation in the sea surface temperatures of the North Atlantic that has widespread effects on climate. Using simulations run on an ocean-atmosphere general circulation model (GCM), it is found that the AMV phase significantly impacts the regional response to CO2: in the extratropical Northern Hemisphere, Eurasia warms more, and North America and the North Pacific warm less, in the warm phase of the AMV. The mechanisms of the AMV-related response are explored using a constructed circulation analog method. Changes in teleconnections between the tropical and extratropical Pacific contribute to the dynamical component of the difference in response to forcing between AMV phases, while differences in sea ice may contribute to the thermodynamic component. Interestingly, some aspects of the AMV-related response are robust with different external forcings. Finally, using simulations run on an atmospheric GCM, the role of sea ice in forcing atmospheric AMV-related anomalies is investigated. It is found that sea ice in the Barents and Greenland Seas plays a large role in forcing local temperature anomalies.

▼ Land subsidence is a common phenomenon worldwide. When mitigation has approached
a limitation, adaptation becomes an important strategy for sustainable development. Specially,
climate
variability and changes can make more serious impacts on coastal areas. This study
focused on adaptation to land subsidence in Chiangyuan area consisting of several coastal
villages, Pingtung county, Taiwan. Little research about the adaptations had been done in this
area, except there was some studies for its awareness.
Using a case study approach with questionnaires, in-depth interview, direct observation,
this study explored past and existed adaptation behaviour in different categories of
stakeholders. Moreover, we also tried to analyze the capacity of these adaptation for future
impacts from land subsidence and flood made by climate change, and could increase the
capacity.
The results have revealed local people in Chiangyuan area had abundant experiences on
adaptations to land subsidence and flood. They used different kinds of adaptation at same time
to cope with flooding, land loss, and salted land problems. The followings have summarized
the adaptation of four categories of stakeholders.
1. for local citizen, the major adaptation is house-elevating, who didnât adopt
house elevating were without budget or planning to move out.
2. for farmer, planting economic fruits with higher tolerance to salt-water.
3. for aquaculture, fish-pond elevating, harvesting earlier, or building fish-pond on
higher land.
4. for school, using water-proof gates or no classes during flooding.
Some suggestion focused on adaptation to land subsidence was also given in this study,
specially for government.

▼ Via the delivery of blood, heart transfers oxygen and nutrients to various organs and is thus a highly influential for circulatory system. To adapt to the variation of physiological conditions, the intensity and frequency of heart beats change with time. Careful observation finds that the time intervals between heartbeats are often different even if the body is at rest. Such heart rate
variability (HRV) has been used to estimate the activity of the autonomic nervous system which can be divided into sympathetic and parasympathetic subsystems both of which can significantly affect the physiology of the human body. As a result, HRV has been used as a physiological indicator to assist doctors in making diagnostic decisions.
Many studies have used HRV to analyze the ECG signal via studying the QRS complex waveform to determine the time intervals between R-peaks and analyze the R-R intervals from time and frequency domains. Different from the conventional R-R Interval based approach, this work introduces new HRV feature variables by computing spectrogram of the ECG signal waveform. In particular, based on the harmonics of the spectrum, we introduce the concepts of modes. By find the relative amount of energy associated with each mode and degree-of-energy-concentration associated with each mode, this work introduces two sets of new HRV features. In addition, we also investigate how these variables change with time and the correlations between these features.
To demonstrate the potential of the proposed features, the differences of the values of the proposed features are compared for healthy individuals versus OSA patients, young versus old and male versus female. The experimental results show the differences between many of the tested features are statistically significant.

▼ My Ph.D. research develops a tiered systematic framework for designing process-independent and
variability-tolerant integrated circuits. This bottom-up approach starts from designing self-compensated circuits as accurate building blocks, and moves up to sub-systems with negative feedback loop and full system-level calibration. a. Design methodology for self-compensated circuits My collaborators and I proposed a novel design methodology that offers designers intuitive insights to create new topologies that are self-compensated and intrinsically process-independent without external reference. It is the first systematic approaches to create "correct-by-design" low variation circuits, and can scale beyond sub-micron CMOS nodes and extend to emerging non-silicon nano-devices. We demonstrated this methodology with an addition-based current source in both 180nm and 90nm CMOS that has 2.5x improved process variation and 6.7x improved temperature sensitivity, and a GHz ring oscillator (RO) in 90nm CMOS with 65% reduction in frequency variation and 85ppm/oC temperature sensitivity. Compared to previous designs, our RO exhibits the lowest temperature sensitivity and process variation, while consuming the least amount of power in the GHz range. Another self-compensated low noise amplifiers (LNA) we designed also exhibits 3.5x improvement in both process and temperature variation and enhanced supply voltage regulation. As part of the efforts to improve the accuracy of the building blocks, I also demonstrated experimentally that due to "diversification effect", the upper bound of circuit accuracy can be better than the minimum tolerance of on-chip devices (MOSFET, R, C, and L), which allows circuit designers to achieve better accuracy with less chip area and power consumption. b. Negative feedback loop based sub-system I explored the feasibility of using high-accuracy DC blocks as low-variation "rulers-on-chip" to regulate high-speed high-variation blocks (e.g. GHz oscillators). In this way, the trade-off between speed (which can be translated to power) and variation can be effectively de-coupled. I demonstrated this proposed structure in an integrated GHz ring oscillators that achieve 2.6% frequency accuracy and 5x improved temperature sensitivity in 90nm CMOS. c. Power-efficient system-level calibration To enable full system-level calibration and further reduce power consumption in active feedback loops, I implemented a successive-approximation-based calibration scheme in a tunable GHz VCO for low power impulse radio in 65nm CMOS. Events such as power-up and temperature drifts are monitored by the circuits and used to trigger the need-based frequency calibration. With my proposed scheme and circuitry, the calibration can be performed under 135pJ and the oscillator can operate between 0.8 and 2GHz at merely 40[MICRO SIGN]W, which is ideal for extremely power-and-cost constraint applications such as implantable biomedical device and wireless sensor networks.

▼ The current study investigated cross-situational personality
variability and its relationship to the personality measures of self-monitoring, Machiavellianism, impression management and authenticity. The 228 participants completed four questionnaires, one for each of the above personality measures, as well as a personality inventory designed to assess the expression of the FFM personality traits in three social contexts; with parents, with friends and with work colleagues. Mean-corrected personality indices were calculated and used to remove any correlational relationship between the trait
variability and means. Systematic cross-situational personality
variability with context-specific patterns was observed, in addition to cross-context consistency of the FFM traits. Contrary to predictions, no significant relationship was observed between mean-corrected personality indices and measures of self-monitoring, Machiavellianism, impression management and authenticity. The results did not support a positive relationship between mean-corrected personality
variability and self-monitoring, Machiavellianism or impression-management. Additionally, the findings did not indicate a link between mean-corrected personality
variability and authenticity.

▼ To further identify physical mechanisms responsible for decadal climate
variability, a combination of ocean reanalyses and coupled climate models were used. A pronounced trend is observed in the first EOF of SST that exhibits a spatial pattern of increasing global temperatures. An analysis of SST, the atmospheric meridional mass streamfunction, and precipitation minus evaporation illustrates a weakening Hadley circulation consisting of an expanded Northern Hemisphere Hadley cell, contracted Southern Hemisphere Hadley cell, and strong Southern Hemisphere Ferrell cell.
There is also pronounced decadal
variability that exhibits a prominent meridional and latitudinal temperature structure, an expanded Southern Hemisphere Hadley cell, and a poleward shift of the Northern Hemisphere Hadley circulation. This
variability resembles a La Niña-like pattern that occurs in both the reanalysis, and the coupled model. As a consequence of tropical Pacific temperature
variability, the Hadley circulation influences extratropical atmospheric circulation in the North Pacific and Atlantic Oceans via an atmospheric teleconnection. A correlation analysis shows a connection between the North Atlantic Oscillation Index and tropical Pacific Ocean temperature, with the Pacific Ocean SST leading by 19 months. North Atlantic related wind patterns force buoyancy changes in deep water formation regions and wave propagations along the western boundary of the North Atlantic Ocean. Thus, it is proposed that SST in the tropical Pacific Ocean forces atmospheric circulations in the North Atlantic Ocean that influence decadal
variability in North Atlantic circulations.

▼ STUDY 1 examined patterns of reaction time (RT)
variability in children with and without ADHD under different motivational contexts. Seventeen children with ADHD and 20 typically-developing controls completed a go-no/go task that included baseline and motivational conditions. Children with ADHD were less accurate than non-ADHD controls in both conditions and responded more slowly than non-ADHD controls when motivational incentives were introduced. Fast-Fourier transform (FFT) analyses indicated that children with ADHD were more variable than non-ADHD controls at both high and low frequencies, but that group differences were greatest at low frequencies. Motivational incentives did not impact patterns of
variability. Results are consistent with previous studies suggesting that low-frequency patterns of RT
variability characterize task performance of children with ADHD. Lack of impact of motivational incentives implicates trait, rather than state, factors in determining patterns of
variability.
STUDY 2 examined physiological correlates of RT
variability in typically-developing children. Twenty-six typically-developing children completed a go-no/go task while physiological measures of attention were collected.
Variability of RTs, as measured by standard deviation of RT (SDRT), was marginally negatively correlated with baseline respiratory sinus arrhythmia (RSA). Although the correlation between electroencephalogram (EEG) beta activity on go trials and SDRT was not significant, the effect size for the correlation was large. Results provide physiological corroboration of theories suggesting that RT
variability in children reflects attentional lapses, specifically difficulties with orienting.

▼ Nowadays stress has become a regular part of life. Stress is difficult to measure because there has been no definition of stress that everyone accepts. Furthermore, if we do not get a handle on our stress and it becomes long term, it can seriously interfere with our health. Therefore, finding the method for stress detection could be beneficial for taking control of stress. Electrocardiogram (ECG) is the measurement of the electrical activity of the heart and represents an established standard in determining the health condition of the heart. The PQRST1[55] complex of ECG conveys information about each cardiac-cycle, where the R-peak is placed in the middle of the PQRST complex and represents the maximum value of the PQRST. Since the PQRST depicts the entire cardio-cycle, the R–peak determines half of the cardio-cycle. The distance between two adjacent R-peaks is defined as a heart rate (HR). The variation of the HR in the specific time frame, defined as heart rate variability (HRV), can reflect the state of the autonomic nervous system (ANS). The ANS has two main divisions, the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The SNS occurs in response to stress while the PNS results from the function of internal organs. The activity of ANS can cause an acceleration (SNS) or deceleration (PNS) of the HR. The SNS activity is associated with the low-frequency range while, the PNS activity is associated with the high frequency component of the HRV. Therefore, the power ratio of the low and high-frequency components of the spectrum of HRV can potentially show whether the subject is exposed to stress or not [48] [50]. In this research, we introduced three new indices, with one of them proposed as a proxy to provide equivalent results in the detection of stress or no-stress states while avoiding complex measurement devices as well as complex calculations. The goal was to find a more time efficient method for fast stress detection which could potentially be used in the applications that run on devices such as a wearable smartwatch in tandem with a smartphone or tablet. The experiment was established to measure the literature proposed index for stress measurement [48][50] as well as our introduced indices. In the experiment, we induced stress to the participants by using mental arithmetic as a stressor [51][53]. Theexperiment contained two kinds of trials. In the first one, the participant was exposed to different amounts of cognitive load induced by doing mental-arithmetic while, in the second one, the participant was placed in a relaxed environment. Each participant in the experiment gave feedback in which period of the experiment he/she felt stress. During the entire experiment, we recorded theparticipant‘s ECG. The ECG was used to calculate HRV which consequently was used for the calculation of the values of the index as proposed from the literature for calculating the level of the stress. The same data was used for the calculation of our introduced indices. The values of our proposed…

▼ Many lithic analyses in recent decades have focused on
the influence of lithic production techniques and artifact stages
in the discard form of stone tools. Assemblage composition has also
been seen to reflect production and reduction activities at
landscape scales. This approach has not yet been applied to the
archaeological record of the north, however, despite its usefulness
in analyzing small-scale sites dominated by lithic materials.
Middle Holocene artifact assemblages in Alaska have frequently been
characterized by the presence or absence of notched projectile
points and microblade technology and assigned to one of two major
categories with differences interpreted in terms of culture
history. Sites with notched projectile points but no microblades
are thought to belong to the Northern Archaic (based on these
levels at the Onion Portage site (Anderson 1968a, b)), while sites
with notched projectile points and microblades are considered
"Tuktu-like" (after the Tuktu-Naiyuk site at Anaktuvuk Pass
(Campbell 1959)), with little consideration of the site function or
reduction activities. Here, a synthesis of over 200 middle Holocene
sites from across Alaska and Yukon is used to show that there is
more
variability in age, distribution, artifact morphology, and
assemblage composition than can be explained within existing
culture-historical frameworks. Detailed cluster analyses, spatial
analyses, and lithic analyses are also used to interpret the lithic
production sequences represented by ten relevant near-surface
archaeological sites from the central and western Brooks Range of
northern Alaska. These data suggest that the archaeological record
for the middle Holocene in northern Alaska is strongly conditioned
by production and maintenance of a variety of tool types as well as
the timing of the addition of raw materials into the
toolkit.

▼ The current investigation examined intraindividual
variability and predictors of this
variability on neuropsychological measures. A total of 50 (39 women and 11 men) independently living, community-dwelling African Americans ranging in age from 50 to 80 years (M = 65.40, SD = 8.53) were asked to complete measures assessing socio-demographics, physical health (i.e. blood pressure and sleep), and cognitive functioning (i.e. executive function, memory, perceptual speed, constructions, and language) over 8 occasions within a 2-3 week period. The current study observed intraindividual
variability across the neuropsychological measures. Results from multilevel modeling suggested that a within-person change in systolic blood pressure was positively associated with performance on executive function (e.g., Letter Fluency), particularly for those participants who on average had high systolic blood pressure and high stress. In contrast, a within-person change in sleep duration was associated with worse performance on constructions and executive functioning (e.g., Letter Fluency). Results also reflected a significant interaction between within-person change in sleep duration and average sleep duration for both perceptual speed (e.g., Number Comparison test) and executive function (e.g., Stroop task). Individuals with low sleep duration on average tended to perform poorly, particularly on those occasions when their sleep duration was below their personal average. In contrast, individuals with high sleep duration on average tended to perform poorly, particularly on those occasions when their sleep duration was above their personal average. Furthermore, daily fluctuations in sleep duration were associated with an increased risk for classification of mild cognitive impairment. The results suggest that
variability on neuropsychological measures may be a useful clinical assessment of older African Americans’ cognitive competency.

▼ Climate extremes associated with climate variability and change are on the rise both in time and space. These extremes have far reaching impacts on socio-economic sectors particularly for countries like Uganda that rely heavily on rain-fed agriculture. The highland cooking banana (Musa genome group AAA-EA) is a major food crop in Uganda. Its continuous cycles of harvests makes it an important crop for enhancing food security and farmers' incomes. Studies have, however, observed continuous decline in banana productivity due to biological and environmental factors including climate extremes.
This study is aimed at investigating the extent of climate variability and climate change and their associated effects on banana production over Uganda. The study used historical observed climate data (1931 to 2013), banana yields (1971 to 2009) and model simulated climate data (1991 to 2100). Climate data analysed consisted mainly of rainfall and temperature. The Providing Regional Climates for Impacts Studies (PRECIS) Regional Climate Model (RCM) was used to simulate high resolution climate projections based on the Special Report on Emission Scenarios (SRES) A1B and A2 scenarios. The study also analysed climate projection data based on the full range of the Inter-governmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) Representative Concentration Pathways (RCPs) as policy scenarios.
In order to detect climate variability and change signals, the observed seasonal climate data were subjected to empirical analyses. This involved determination of the first upto fourth moments. The shift in the first moment constituted the trend whose significance was evaluated using the Mann-Kendall test. The moments of both standardized climate data and banana yields were determined and used to identify linkages between current climate variability and banana yields. The Crop Water Assessment Tool (CROPWAT) was used to determine banana water requirements, moisture deficits and yield reductions for the current period. The Pearson’s product-moment correlation coefficient, Refined Wilmott Index and Root Mean Square Errors (RMSE) were used to assess climatemodel performance. Empirical Orthogonal Functions (EOFs) were used to characterize modes of climate variability in both observed and model seasonal rainfall. Comparative graphical analysis based on geo-spatial mapping techniques was used to analyse and map climate variability and change patterns from the high resolution future climate projection information for rainfall, temperature and soil moisture content based on different scenarios. The response of banana growth to expected changes in temperature under
vi
A1B and A2 scenarios was assessed using a banana-temperature growth regression model. The FAO Eco-crop tool was used to estimate suitable climate conditions for optimal banana growth. The mapping of future suitability of banana during the period (2041-2080) was undertaken using ARCGIS.
The results showed that inter annual seasonal rainfall and temperature trends varied…

▼ Climate variability and change is increasingly being recognized as a critical challenge to pastoral
production systems in the arid and semi-arid rangelands. The projected climate scenarios are
expected to aggravate some of the existing vulnerability of natural resource-dependent
communities, and likely to impose new risks beyond the range of current experiences. An
explicit understanding of households‟ vulnerability to climate variability and adaptation
strategies is, therefore, crucial for targeting appropriate resilience interventions in pastoral
environments. This study focused on better understanding of climate variability and change, in
order to provide insights on pastoralists‟ risk management adaptations at a micro-level. In
addition, the study investigated vegetation responses to precipitation anomalies in Turkana
County of Kenya.
The research study used Mann-Kendall test statistics to investigate long-term rainfall (19502012)
and temperature (1978-2012) changes. Household questionnaire survey, focus group
discussion and key informants‟ interviews were used to collect primary data at household and
community levels. A total of 302 households were sampled using multi-stage sampling
technique, and information obtained analyzed using descriptive statistics and ordinal logistic
regression model. In addition, Normalized Difference Vegetation Index (NDVI) data derived
from Advance Very High Resolution Radiometer (AVHRR) satellite were overlaid with
precipitation to generate vegetation maps. Analysis of variance (ANOVA) was used to analyse
vegetation species richness and abundance in the study area.
The result revealed high inter-annual (coefficient of variation > 90%) rainfall variability, with
seasonal uncertainty. There were more years with below normal rainfall than those with mean
rainfall above long-term mean (LTM). Results indicate that extreme drought events have
increased over the last 63 years, with 28.5% occurrences between 1950 and 1970, to 47.9% over
the last two decades between 1990 and 2012. Further, the study revealed that the area is warming
at 0.13°C, with a significant (p<0.05) rise in both minimum (0.2°C), maximum (0.1°C)
temperature for the period 1979 - 2012. Pastoralists‟ perception of changes in climate
climate variability and change are being felt by many households in Turkana. The vulnerability
index analysis showed that majority of households were moderately (44%) to highly (27%)
vulnerable to climate-induced stresses. Factor estimates of the probit model further revealed that
the main determinants of pastoralists‟ vulnerability were sex of household head, number of
dependents, marital status, social linkages, access to extension services and early warning
information, herd structure and mobility, distance to markets, and access to affordable credit.
The results highlight the need for interventions to empower women in the access to education,
affordable credits, livelihood diversification opportunities, and to resources that can strengthen
households‟…

▼ ABSTRACT
This paper studies the impact of seasonality on agricultural productivity in Bangladesh for the period of 1980-2013 for 7 regions. This study exploits regional fixed effect to estimate the impact of both observed and unobserved effects on agricultural productivity in order to control for regional differences. I used a panel dataset for the fixed and random effect regression model to control omitted variables bias and endogeneity. Findings from this study expressed that the effects of all the climate variables are not significant to rice, wheat, and pulse yield. Maximum temperature and minimum temperature wet for rice, minimum temperature dry and rainfall dry for wheat, and maximum temperature dry, rainfall wet, and humidity in both season for pulse are statistically significant and contribute to the crop production. Overall, climatic variables are of paramount importance for seasonality and agricultural productivity in Bangladesh.

▼ Subantarctic New Zealand is an oceanographycally dynamic region with the Subtropical Front (STF) to the north and the Subantarctic Front (SAF) to the south. This thesis investigates the ocean structure of the Campbell Plateau and the surrounding New Zealand subantarctic, including the spatial, seasonal, interannual and longer term
variability over the ocean properties, and their connection to atmospheric
variability using a combination of in-situ oceanographic measurements and remote sensing data.
The spatial and seasonal oceanographic structure in the New Zealand subantarctic region was investigated by analysing ten high resolution Conductivity Temperature and Depth (CTD) datasets, sampled during oceanographic cruises from May 1998 to February 2013. Position of fronts, water mass structure and changes over the seasons show a complex structure around the Campbell Plateau combining the influence of subtropical and subantarctic waters.
The spatial and interannual
variability on the Campbell Plateau was described by analysing approximately 70 low resolution CTD profiles collected each year in December between 2002 and 2009. Conservative temperature and absolute salinity profiles reveal high
variability in the upper 200m of the water column and a homogeneous water column from 200 to 600m depth. Temperature
variability of about 0.7 °C, on occasions between consecutive years, is observed down to 900m depth. The presence of Subantarctic Mode Water (SAMW) on the Campbell Plateau is confirmed and Antarctic Intermediate Water (AAIW) reported for the first time in the deeper regions around the edges of the plateau.
Long-term trends and
variability over the Campbell Plateau were investigated by analysing satellite derived Sea Level Anomalies (SLA) and Sea Surface Temperature (SST) time series. Links to large scale atmospheric processes are also explored through correlation with the Southern Oscillation Index (SOI) and Southern Annular Mode (SAM). SST shows a strong seasonality and interannual
variability which is linked to local winds, but no significant trend is found. The SLA over the Campbell Plateau has increased at a rate of 5.2 cm decade⁻¹ in the last two decades. The strong positive trend in SLA appears to be a combination of the response of the ocean to wind stress curl (Ekman pumping), thermal expansion and ocean mass redistribution via advection amongst others.
These results suggest that the
variability on the Campbell Plateau is influenced by the interaction of the STF and the SAF. The STF influence reaches the limit of the SAF over the western Campbell Plateau and the SAF influence extends all around the plateau. Results also suggest different connections between the plateau with the surrounding oceans, e.g., along the northern edge with the Bounty Trough and via the southwest edge with the SAF. A significant correlation with SOI and little correlation with SAM suggest a stronger response to tropically driven processes in the long-term
variability on the Campbell Plateau.
The results of this thesis provide a new…

▼ Romantic couples must regularly navigate interactions to maintain satisfying relationships, but it is unclear how people’s
variability in communication behaviour is linked to relationship wellbeing. Varying communication behaviours may display responsiveness to a partner’s needs by adjusting behaviour appropriately. Or else, inconsistent behaviour may undermine partner trust by fuelling uncertainties about commitment. Across two studies, we investigated how a person’s
variability of communication behaviour was associated with their own wellbeing and their partner’s wellbeing. Specifically, we assessed spin, a measure of how often a person switches between communication behaviours. We predicted that switching between positive behaviours would be linked with higher relationship wellbeing but, conversely, switching between negative communication behaviours would be linked with lower wellbeing. We assessed spin in positive and negative forms of relationship behaviour over three weeks (Study 1; 78 couples) and over a single interaction (Study 2; 112 couples). Effects for spin in positivity emerged only in Study 1. For women, switching daily positive behaviour over three weeks was associated with higher partner relationship wellbeing but unexpectedly lower wellbeing for women (controlling for mean-level positivity). This suggests that, for women, being responsive to partners in diverse ways is beneficial for the partner but comes at a personal cost. Effects for spin in negativity emerged in both studies. Switching negative behaviour was linked with lower partner wellbeing in both studies, indicating that use of different negative behaviours is more dysfunctional than the sum of individual relationship behaviours. Across both studies, additional tests illustrated that these effects were independent and not due to
variability in the magnitude of behaviours. Our findings show variable behaviour may benefit partner wellbeing when behaviour is positive, but inconsistent negativity interrupts intimacy processes to undermine wellbeing. Our research highlights the importance of considering behavioural
variability when studying relationship maintenance processes over time.

▼ Fifty percent of drives have been found to frequently violate speed limits (OECD/ECMT, 2006), and speed limit compliance appears to depend on the perceived credibility of a road’s speed limit (Goldenbeld & van Schagen, 2007). Credibility of speed limits, in turn, appears to be determined by the match between drivers’ speed preferences and the design of the road (Goldenbeld & van Schagen, 2007). Yet, a challenge has been that not all drivers’ prefer the same speeds, and individual differences with regards to speed preference lead to speed
variability and speed conflicts in traffic (Elvik, 2010). The aim of this thesis was to explore whether the speed drivers like to drive when motivated by different driving goals (speed preference) correspond to the speeds that they actually drive on those same roads (speed choice). Additionally, this thesis sought to explore the relationship between speed preference and risk perception. Data was collected in two ways, from a speed gun and from a questionnaire. The speed gun collected on-road measures of driving speeds on seven different roads, while the questionnaire collected measures of drivers’ self-reported speed, speed preference and risk perception. For the speed preference measures, participants were asked what speed they would choose on a given road when: 1) motivated by safety, 2) considering fuel savings, or 3) motivated by fun, and additionally 4) what speed they usually drove on the road. In total 200 drivers were interviewed at five different parking lots, and they referred to the seven roads that were sampled with the speed gun. The results indicated that speed preference helped to explain actual driving speeds. More specifically, drivers’ different driving goals and their large individual differences with regards to speed preference corresponded to different speed choices. No relationship was found, however, between drivers’ speed preferences and their risk perceptions. The results are discussed with regards to implications for the problem of speed
variability in traffic.

▼ The population of manual wheelchair users is increasing notably faster than the general population. Manual wheelchair users have a disproportionately high prevalence of shoulder pain and injury, most likely due to the repetitive and load-bearing nature of propulsion. Previous wheelchair propulsion studies have reported on the kinematics of propulsion using traditional time-series data (e.g., propulsion cycle time, shoulder range of motion, et cetera) in an attempt to predict individuals at risk for developing shoulder pathology. However, a reliable method of prediction has yet to be attained using these metrics. Due to the repetitive nature of wheelchair propulsion cycle-to-cycle
variability (i.e., inter-cycle
variability) of the traditional kinematic indices may provide additional insight into the movement patterns of the shoulder during wheelchair propulsion. The purposes of these studies were to quantify baseline kinematic
variability of the shoulder during manual wheelchair propulsion, quantify the effects of multiple speeds on shoulder kinematic
variability, and quantify the effects of an exercise intervention on shoulder kinematic
variability. There is some evidence that temporal and spatial kinematic
variability may provide additional insight into wheelchair propulsion biomechanics beyond that of traditional measures of kinematics. However, when extrapolating the results of these studies to studies previously reported, discrepancies arise and are very likely due to methodological differences. These issues are discussed and a protocol was developed to help contribute to the standardization of biomechanical testing for wheelchair propulsion.

▼ Background: Changes in temperature, rainfall and relative humidity due to climate change are expected to directly influence malaria transmission dynamics, by modifying the behavior and geographical distribution of malaria vectors while shortening the sporogonic cycle of the parasite in the vector. These changes will have varying effects on malaria incidence in different eco-epidemiological settings. The aim was to examine the impact of climate variability on malaria incidence in three micro-epidemiological ecosystems in the forest zone of Ghana, Ashanti Region.
Methods: Data on climatic variables (rainfall, temperature and humidity) from January 2008 to- October 2009 were obtained from the two weather stations. Hospital based confirmed malaria incidence data were obtained for the same period from Akropong (rural) hospital whereas malaria incidence data were obtained from January 2008-June 2009 and January 2008-August 2009 for Emena (peri-urban) and Atonsu (urban) hospitals respectively. Microscopy was used to identify the predominant Plasmodium species. Spearman’s correla-tion analysis and cross correlation analysis that allowed a time-lag of 0-3 month were performed to examine the role of climatic variables on malaria incidence.
Results: There was a direct correlation between monthly malaria incidence and monthly climatic variables at different time-lags and location. At every study site, different climatic variables were seen to play different roles on the occurrence of malaria. At Akropong and Emena, the study indicates that rainfall and minimum temperature are the major drivers of malaria incidence though this relationship was significant at different time-lags in different eco-epidemiological settings. At Atonsu, the study indicates that rainfall and maximum tem-perature are the major contributors to malaria incidence.
Conclusion: Climatic variables have direct and indirect influence on malaria incidence and these variables can predict malaria inci-dence and be suited for forecasting the malaria occurrence in areas with similar ecological features in the Ashanti Region of Ghana.

▼ Generating new information using traditional agricultural trials which are expensive is not sufficient to meeting novel agro-technologies. Planting date (PD), low soil fertility and climate change influences maize (Zea mays L.) growth and yield. Local-scale impacts of future climate change (CC) and variability (CV) on PD, N fertilizer rate (N), cultivar, maize growth, and yield is not well documented in Zambia. The impact of climate change and extreme climate indices on maize yield in AERII are carried out at large spatial scales, missing out on local-scale impacts, mitigation and adaptation potentials under which farmers operate.
Statistical downscaling models such as stochastic weather generator (Long Ashton Research Station Weather Generator [LARS-WG]) and delta-based methods (Agricultural Model Intercomparison and Improvement Project (AgMIP) protocols) have not been applied locally to assess the impact of climate change. Additionally, the AgMIP protocols have not been applied to downscale climate scenarios using Representative Concentration Paths (RCP4.5 and RCP8.5). Changes in temperature and precipitation would have a significant impact on maize phenology and yield. Two field experiments were conducted at Zambia Agriculture Research Institute at Mount Makulu (Lat: 15.550o S, Lon: 28.250o E, altitude: 1213 m) in Zambia to assess the effect of PD, N and cultivars on yield and yield parameters and to predict the impact of climate change on maize productivity in the 2050s. The irrigated experiment was arranged in a Split-plot design with maize cultivars (ZMS606, PHB30G19and PHB30B50) and N fertilizer rates (67.20, 134.40 and 201.60 kg N ha-1) as main-plots and sub-plots, respectively. These cultivars were selected as major cultivars planted by small scale farmers and their long commercial life. The rainfed experiment was a split-split plot design with PDs, cultivars, and N as the main-plots, sub-plot, and sub-subplots, respectively. Each field experiment had three replicates.
Daily weather data were obtained from the Zambia Meteorological Department and AgMERRA. Plant growth, grain, and biomass yield were observed at phenological stages. The ANOVA for grain yield and yield parameters were computed using the sp.plot and ssp.plot functions in Agricolae R package. Significant differences between means were tested using Fisher-LSD Test (p<0.05). Site weather data, soil data, cultivar characteristic, and management required by the crop models were also collected. The rainfed (2016/2017) and irrigated (2016) field experimental data were used for calibrating and validating the crop simulation models (CSMs), respectively.
Expert Team on Sector Specific Indices (ET-SCI) of extreme temperature and precipitation were computed after checking weather data (1963-2012) for quality, homogeneity, and trends using ClimPACT2. The APSIM-Maize v7.9 and CERES-Maize v4.7 models were calibrated using rainfed experimental site data. Days after planting (DAP) to anthesis, and maturity, grain and biomass yield, LAI and soil water content…

▼ Dissolved oxygen is a widely observed chemical quantity in the oceans along with temperature and salinity. Changes in the dissolved oxygen have been observed over the world oceans. Observed oxygen in the Ocean Station Papa (OSP, 50°N, 145°W) in the Gulf of Alaska exhibits strong
variability over interannual and decadal timescales, however, the mechanisms driving the observed
variability are not yet fully understood. Furthermore, irregular sampling frequency and relatively short record length make it difficult to detect a low-frequency
variability. Motivated by these observations, we investigate the mechanisms driving the low-frequency
variability of oxygen in the subpolar North Pacific. The specific purposes of this study are 1) to evaluate the robustness of the observed low-frequency
variability of dissolved oxygen and 2) to determine the mechanisms driving the observed
variability using statistical data analysis and numerical simulations. To evaluate the robustness of the low-frequency
variability, we conducted spectral analyses on the observed oxygen at OSP. To address the irregular sampling frequency we randomly sub-sampled the raw data to form 500 ensemble members with a regular time interval, and then performed spectral analyses. The resulting power spectrum of oxygen exhibits a robust low-frequency
variability and a statistically significant spectral peak is identified at a timescale of 15-20 years. The wintertime oceanic barotropic streamfunction is significantly correlated with the observed oxygen anomaly at OSP with a north-south dipole structure over the North Pacific. We hypothesize that the observed low-frequency
variability is primarily driven by the
variability of large-scale ocean circulation in the North Pacific. To test this hypothesis, we simulate the three-dimensional distribution of oxygen anomaly between 1952 to 2001 using data-constrained circulation fields. The simulated oxygen anomaly shows an outstanding
variability in the Gulf of Alaska, showing that this region is a hotspot of oxygen fluctuation. Anomalous advection acting on the climatological mean oxygen gradient is the source of oxygen
variability in this simulation. Empirical Orthogonal Function (EOF) analyses of the simulated oxygen show that the two dominant modes of the oxygen anomaly explains more than 50% of oxygen variance over the North Pacific, that are closely related to the dominant modes of climate
variability in the North Pacific (Pacific Decadal Oscillation and North Pacific Oscillation). Our results imply the important link between large-scale climate fluctuations, ocean circulation and biogeochemical tracers in the North Pacific.
