▼ Following Toyota's dramatic rise to prominence within the automotive industry in the late 1980's, firms around the globe have widely sought to adopt Lean Six Sigma (LSS) as a means of reducing costs, improving quality, and gaining an overall competitive advantage. While the operational benefits of LSS are largely undisputed, there are criticisms of the movement with regards to its effect on firm innovation capability. Prior academic studies investigating the relationship between LSS and innovation are largely conceptual in nature, rely heavily on qualitative data, and display a high degree of variability in results. The objective of this work was to empirically confirm whether LSS adoption had a positive, negative, or neutral impact on firm innovation performance.Financial data was collected for 151 publicly traded firms over the period from 1985 to 2018. The year of company-wide adoption of LSS was identified for each sample firm. Firms were paired with industry rivals using Coarsened Exact Matching (CEM), and statistical regressions were performed to show correlations between LSS implementation (as measured by inventory turns) and innovation performance (as measured by Total Factor Productivity, Research Quotient, and Tobin's Quotient). Regression results indicated that LSS implementation had a positive correlation with firm process innovation performance and the overall market perception of firm innovation and value, and a negative-to-neutral correlation with firm product innovation performance. Additional regressions performed at the industry-sector level revealed that the LSS-innovation relationship varies greatly by industry environment and is subject to unique industry effects and management implementation decisions.

▼ The propargyl radical, the most stable isomer of C3H3, is very important in combustion reactions. However, theoretical calculations have never been able to find a strong absorption around 242 nm as seen in experiments. In this study, we calculated the electronic energy levels of the propargyl radical using highly accurate multireference methods, including multireference configuration interaction singles and doubles method with triples and quadruples treated perturbatively [denoted as MRCISD(
TQ)], as well as second and third order generalized Van Vleck perturbation theories (GVVPT2 and GVVPT3). Calculations indicate that this absorption can be solely attributed to a Franck-Condon-allowed transition from the ground B1 state to the Rydberg-like first A1 excited state. Calculations also show that GVVPT2 with a relatively small active space fails to capture enough Rydberg character of this excited state, while it can be recovered by GVVPT3, MRCISD, and MRCISD(
TQ).
In order to speed up MRCISD(
TQ) calculations, the triple and quadruple (
TQ) perturbative corrections, the most time-consuming part of MRCISD(
TQ) calculations, were parallelized using Message Passing Interface (MPI). The MRCISD(
TQ) method is organized in the framework of macroconfigurations, which allows the use of incomplete reference spaces and provides an efficient means of screening large number of non-interacting configuration state functions (CSFs). The test calculations show that the parallel code achieved close to linear speed-up when the number of CSFs in each macroconfiguration is small. The speed-up suffers when large numbers of CSFs exist in only a few macroconfigurations.
The computer algorithm for second-order generalized van Vleck multireference perturbation theory (GVVPT2) was similarly parallelized using the MPI protocol, organized in the framework of macroconfigurations. The maximum number of CSFs per macroconfiguration is found to have less influence on the MPI speedup and scaling than in the case of MRCISD(
TQ).
It was previously found that unrestricted local density approximation (LDA) orbitals can be used in place of MCSCF to provide orbitals for GVVPT2. This inspired us to use the more controllable restricted density functional theory (DFT) to provide unbiased orbitals for GVVPT2 calculations. In this study, the relationship between restricted DFT and unrestricted DFT were explored and the restricted DFT results were obtained by utilizing subroutines from unrestricted DFT calculations. We also found that the DIIS technique drastically sped up the convergence of RDFT calculations.
Plane wave DFT methods are commonly used to efficiently evaluate solid state materials. In this work, the electronic properties of pristine graphene and Zn-phthalocyanine tetrasulfonic acid (Zn-PcS) physisorbed on single-layer graphene were calculated using plane wave DFT. The Perdew-Burke-Ernzerhof functional with dispersion correction (PBE-D2) was used. The densities of states were…

▼ The United States public schools promote inclusion and educational equity among diverse student populations. Considerable and growing numbers of students with categorical disabilities and Limited English Proficiency (LEP) are enrolled in regular classrooms. The systemic barriers in learning that they have could impact teacher perceptions and decisions about teaching practices as well as the teaching profession. These students have challenged K-12 science, technology, engineering, and mathematics (STEM) teachers to provide high-quality, accommodative service and equitable educational opportunities in an increasingly STEM-infused society. Professional development associated with teaching students with disabilities and LEP is critical to inform in-service STEM teachers with these students' learning needs and promote student success. Effective preparation and support help maintain teacher satisfaction and retention within the teaching profession. However, the levels and perceptions of STEM teacher participation in such professional development, and whether the service load and professional development regarding the concerned groups of students associated with teacher satisfaction and retention remain unclear.
This dissertation addresses these issues through two research studies using secondary analysis of the 2011-2012 School and Staffing Survey Teacher Questionnaire (SASS
TQ) national dataset. The first study focused on K-12 STEM educator participation and perceived utility regarding their professional development experience concerning students with disabilities and LEP. Quantitative analysis revealed an overall lower level of participation and perceived utility of such professional development for STEM educators compared to all other educators. The second study examined teacher satisfaction and intent to remain in teaching, as well as their relationships to teacher service load and professional development specific to students with disabilities and LEP. Results indicated that K-12 STEM educators were less likely to feel satisfied or intent on remaining in teaching, compared to the remainder of the teaching population. Logistic regressions showed that service load of students with LEP predicted teacher satisfaction and participation in professional development concerning students with disabilities associated with teacher intent to remain in STEM education, especially for science educators. These findings collectively suggested the necessity and demands of sufficient and useful professional development offerings regarding the two concerned groups of students in inclusive STEM education settings.

▼ Dissertação de Mestrado em Engenharia do Ambiente
A indústria têxtil caracteriza-se por gerar efluentes com uma elevada carga orgânica devido à manipulação de diversas soluções coradas envolvendo compostos químicos sintéticos resistentes em geral a tratamentos biológicos convencionais. A descarga deste tipo de efluentes pode causar grandes mudanças no meio receptor, traduzindo-se num grave problema ambiental.
Os corantes têxteis são compostos normalmente aplicados em solução e que se fixam de alguma maneira a um substrato. Podem ser classificados de acordo com a sua cor, natureza química e o método de aplicação. Os corantes azo são caracterizados pela dupla ligação entre átomos de azoto (-N=N-). Esta ligação define a cor do corante sendo o tipo de corante mais produzido a nível mundial e, consequentemente, o mais estudado no que diz respeito à sua remoção de efluentes líquidos. O corante Laranja II é um dos corantes azo com mais aplicabilidade na indústria têxtil, devido à sua fácil solubilidade em água e ao seu baixo preço.
Este trabalho teve como objectivo geral estudar a capacidade fotodegradativa do corante Laranja II, em solução aquosa, por camadas de TiO2 e ZnO depositadas por serigrafia plana em peças cerâmicas vidradas de uso comum. Para isso foram realizados ensaios para avaliar o efeito de diferentes variáveis como o pH, a temperatura, o tipo de fotocatalisador, a quantidade de fotocatalisador, a concentração de corante, a presença de agentes oxidantes e a intensidade de radiação UV.
O processo de descoloração do Laranja II envolveu soluções preparadas em laboratório sob o efeito de radiação UV. Os ensaios realizaram-se num reactor cilíndrico, construído para o efeito, onde foram dispostas previamente as peças cerâmicas. Foram avaliadas duas lâmpadas de vapor de mercúrio Heraeus (TNN 15/32 e TQ 150) como fonte de radiação.
O uso de catalisadores depositados em azulejos cerâmicos é uma técnica muito promissora, obtendo-se descolorações do Laranja II superiores a 90 %, revelando que sob radiação UV, com a lâmpada de vapor de mercúrio TNN 15/32, o TiO2 apresenta melhor desempenho com uma descoloração máxima de 98 % a uma taxa de 14,8x10-3 min-1 em 300 minutos à temperatura ambiente (≈ 20ºC). Com ZnO foi obtida uma descoloração máxima de 94 % a uma taxa de 9,7x10-3 min-1. A variação de pH não influenciou de forma significativa a capacidade fotodegradativa do TiO2. O desempenho das camadas activas é tanto mais eficaz quanto mais baixa a concentração inicial do corante a degradar. A adição de uma quantidade de H2O2 conduz a uma melhoria na descoloração do Laranja II, diminuindo o tempo reaccional para 120 minutos.
A deposição de óxidos em peças cerâmicas apresenta-se como uma boa alternativa ao uso de óxidos em suspensões, evitando a etapa de remoção dos óxidos no final do tratamento. Além disto são materiais de fácil limpeza e resistentes, apresentando uma grande fiabilidade podendo ser usados de forma sucessiva sem comprometer de forma significativa a capacidade fotodegradativa dos óxidos.

▼ The thesis titled "Clinical and biological characterization of myelodysplastic syndromes with 5q
deletion" is based on a compilation of three papers published in international journals in the
field of hematology‐oncology. The main objective of this thesis is to go in depth to the genetic
and clinical study of myelodysplastic syndromes (MDS) who have a deletion of the long arm of
chromosome 5 (5q‐).
The approach of this disease was made with molecular cytogenetic techniques. In the first
paper, we studied by FISH more than 600 patients with MDS without 5q deletion by
conventional cytogenetics. 5q deletion was detected in 6% of cases. It is noteworthy that in
those cases in which no cytogenetic information was available, as the culture had no
metaphases, 5q deletion was detected in 20% of cases. These results are important because
there is a treatment that is highly effective in patients with this cytogenetic alteration.
In the second study, we have analyzed the natural history of MDS with 5q deletion. We
collected clinical and biological data of more than 500 patients with MDS and 5q deletion by
conventional cytogenetics. This study allowed to define the impact, on survival and disease
progression to acute myeloid leukemia, of the cytogenetic alterations accompanying the
deletion 5q. This study has determined that the presence of a single cytogenetic abnormality
accompanying the 5q deletion does not have a significant effect on overall survival but does
have impact on disease progression in acute myeloid leukemia.
The third work is based on the genetic study, using direct sequencing and genomic
microarrays, and its correlation with lenalidomide treatment response. The importance of this
work is that around 25% of patients do not respond to treatment with lenalidomide and the
reason is unknown. This study has determined that the presence of an accompanying
cytogenetic alteration is associated with a non‐response to treatment. In addition, the
presence of mutations in the TP53 gene showed a tendency to not predict response to
treatment.
This thesis has allowed to a better clinical, biological and genetic characterization of MDS with
deletion 5q, and have helped the scientific community to better understand the natural history
of the disease.

▼ Endocrine Disrupter Compounds (EDCs) like pesticides, alkylphenols and hormones among other classes of compounds are responsible for alterations in the endocrine system functions. Endocrine disruption occurs when EDCs interact with the hormone receptors, altering the natural response patterns of the endocrine system. Aquatic organisms, such as fish, are able to accumulate EDCs residues in concentration several times higher than the surrounding water. Consequently, fish is a major source of contamination for both top predators and human consumers. This study aimed to develop and validate a fast method for the determination of 40 endocrine disrupters in fish fillet, using modified QuEChERS and Gas Chromatography coupled with Mass Spectrometry in tandem, using a triple quadrupole analyzer (GC-(TQ)MS/MS). A factorial design was performed to optimize the extraction procedure, which consist of the extraction of 10.0 g of fish fillet with 10.0 mL of acetonitrile with 1% (v/v) of acetic acid followed by manual shaking for 1 min. In the partition step 2.0 g of sodium chloride, 1.7 g of anhydrous sodium acetate and 0.3 g of anhydrous magnesium sulfate were added, followed by shaking and centrifugation at 3400 rpm for 8 min. Then the extract was transferred to a 15 mL polypropylene tube containing the C18 and PSA sorbents, beyond the anhydrous magnesium sulfate. After shaking and centrifuging, the supernatant was filtered and analyzed by GC-(TQ)MS/MS. The method was validated by spiking the blank sample at three concentration levels (10, 25 and 50 Ug kg-1) obtaining recovery values between 70.1 to 120.0% for 36 of the 40 endocrine disrupters evaluated. RSD values below 20% ensured the good precision of the method. The linearity was evaluated using the coefficient of determination (r2) with values higher than 0.996 for all compounds. The matrix effect was evaluated, and it was pretty intense for most compounds, with values exceeding 10%. This effect was compensated using analytical curves obtained with standards prepared in blank matrix extracts. This method was applied in 6 samples of fish fillet from different species. Residues of bisphenol A, chlorpyrifos and bifenthrin were detected. Therefore, the modified QuEChERS method proved to be appropriated for the determination of endocrine disrupters in fish fillet using GC-(TQ)MS/MS since it showed to be effective and can be applied to routine analysis.
Compostos conhecidos como disruptores endócrinos (DEs), tais como agrotóxicos, alquilfenóis, hormônios, dentre outras classes de substâncias são responsáveis pela alteração de funções do sistema endócrino. Esse efeito ocorre quando os DEs interagem com os receptores hormonais, alterando os padrões de resposta natural do sistema endócrimo. Os organismos aquáticos, como os peixes são capazes de acumular concentrações de DEs várias vezes superiores a água ao seu redor. Consequentemente, os peixes são uma importante fonte de contaminação para seus predadores e consumidores humanos. O presente trabalho teve como objetivo desenvolver…

▼ One electron oxidation of DNA has been studied extensively over the years. When a charge is injected into a DNA duplex, it migrates through the DNA until it reaches a trap. Upon further reactions, damage occurs in this area and strand cleavage can occur. Many works have been performed to see what can affect this damage to DNA. Netropsin is a minor groove binder that can bind to tracts of four to five A:T base pairs. It has been used in the studies within to determine if it can protect DNA against oxidative damage, caused by one-electron oxidation, when it is bound within the minor groove of the DNA. By using a naphthacenedione derivative as a photosensitizer, several DNA duplexes containing netropsin binding sites as well as those without binding sites, were irradiated at 420 nm, analyzed, and visualized to determine its effect on oxidative damage. It has been determined netropsin creates a quenching sphere of an average of 5.8 * 108 Šwhether bound to the DNA or not. Herein we will show netropsin protects DNA against oxidative damage whether it is free in solutions or bound within the minor groove of a DNA duplex.

▼ Die noodsaaklikheip om produktiwiteit en kwaliteit in hoer onderwys te verbeter, het
aanleiding gegee tot die relatief nuwe totale kwaliteitbestuur (TQM)-beweging by
tersiere onderriginstellings soos universiteite en technikons.
Die integrering van die totale kwaliteitverwante konsepte van strategiese TOM
-intensie, eksterne omgewingsfaktore, bestuur se reaksie, kwaliteitstelseleffektiwiteit
en deurlopende verbetering in 'n model, dui die gekombineerde gevolge
van genoemde konsepte op die institusionele verbetering van technikons en •
universiteite aan. Die belangrikste veranderlikes (binne bogenoemde dimensies van
die model) wat vir institusionele verbetering by onderskeidelik universiteite en
technikons verantwoordelik is, toon ooreenstemming - universiteite en technikons
verskil egter ten opsigte van ander minder belangrike veranderlikes.
Die funksionering van die model is soos volg: Die bestuur (akademies en
administratief) van die tersiere onderriginstelling identifiseer en erken, onderhewig
aan aspekte soos leierskap, kennis, ervaring, en aanvaarding, sekere eksterne
omgewingsfaktore wat verband hou met die klientebehoeftes (ekstern en intern) en
institusionele verbetering. Gegewe genoemde beperkings en faktore besluit bestuur
op die (suboptimale) strategiese TQM-intensie om aan klientebehoeftes te voldoen.
Die strategiese TQM-intensie sal nou saam met bestuur se reaksie (deur die
toepassing van die TQM-beginsels en -filosofie) wat die effektiwiteit van die
kwaliteitstelsel bepaal, bepaal op watter kwaliteitvlak die instelling sal opereer. Die
kwaliteitstelsel bestaan uit die bestuur-, tegniese. en sosiale stelsel, en is weer eens
I
aan deurlopende verbetering onderhewig. (Die bestuurstelsel dien as integreerder
van die ander twee stelsels.) Die eindresultaat van die toepassing van die TQMfilosofie
en -beginsels is institusionele verbetering.
Verder kan die model en die resultate van hierdie studie deur universiteite en
technikons gebruik word by die verbetering/implementering van hulle eie, unieke
totale kwaliteitimplementeringsmodel(le) - 'n uitgebreide implementeringsmodel is vir
die rede voorgehou.
Laastens kan die (verkorte) meetinstrumente wat vir universiteite en technikons
onderskeidelik bepaal is, gebruik word om die sukses met die implementering van
TQM by 'n individuele instelling te meet.; The necessity to improve productivity and quality in higher education has resulted in
the relatively new movement of Total Qua~ity Management(TQM) at tertiary
institutions such as universities and technikons.
The integration of the total quality-related concepts of_ strategic TQM intent,
external environmental factors, reaction of management, effectiveness of the quality
system and continuous improvement in a model, can be used to indicate their
combined results on the institutional improvement of technikons and universities.
The most important variables (within the above-mentioned dimensions of the model)
responsible for institutional improvement at universities and…
