Gender dysphoric individuals are a growing number in society and like other minority groups they are at risk of falling victim to discrimination. In an attempt to understand how attitudes affect discriminatory behaviour in a recruitment situation, future recruiters’ implicit and explicit attitudes toward gender dysphoric individuals were measured in relation to a résumé choice task. Implicit attitudes were measured with an Implicit Association Test and explicit attitudes with a transphobia scale. An independent sample t-test was conducted (N = 42), to measure if implicit attitudes differed between participants who chose a résumé of a gender dysphoric individual and participants that chose a résumé of a non-gender dysphoric individual. Although no significant differences in attitudes between the two groups were found, the results indicate other noteworthy differences in that a vast majority of participants had negative implicit attitudes toward gender dysphoric individuals in contrast to their positive explicit attitudes.

Problemet idag är att det ofta är många sökande till varje ledig tjänst som utannonseras. För att få komma på anställningsintervju och presentera sig krävs det att man klarar sig förbi första gallringen. Grundtanken med uppsatsen var att ta reda på om det personliga brevet har någon betydelse i rekryteringsprocessen. Detta gjordes med hjälp av följande fem frågeställningar: hur går rekryteringsprocessen till fram till att ansökningarna når företaget, vad sker från det att ansökan når företaget till att man kallar till intervju, vilken betydelse har kravprofilen vid bedömningen av det personliga brevet, vilken betydelse har de personliga egenskaperna samt vilken betydelse har det personliga brevet i urvalsprocessen. Frågeställningarna omfattar hela rekryteringsprocessen för att man ska kunna sätta in det personliga brevet i sitt sammanhang och på så sätt få en bild av dess betydelse. För att uppfylla syftet att besvara frågeställningarna användes en litteraturstudie samt en intervjustudie som metod. Intervjumanualen grundades på frågeställningarna. Intervjuerna utfördes på fyra privata företag med olika inriktningar och storlek samt en offentlig myndighet. Samtliga fem informanter hade erfarenhet av rekrytering och personalfrågor. Resultatet av de två första frågeställningarna grundades på båda studierna och svaret visade att informanterna arbetade snarlikt samt i enlighet med litteraturen när det gäller rekryteringsprocessen. Övriga frågeställningar besvarades med hjälp av intervjustudien och vi tycks kunna se ett mönster hur rekryterarna resonerar kring det personliga brevet. De anser att brevet inte har någon större betydelse utan menar att Curriculum Vitae (CV:n), som de först granskar, betyder mer. När rekryteraren bedömer det personliga brevet görs det subjektivt vilket medför en risk att sållningen inte går rätt till. I slutdiskussionen ges förslag på hur man skulle kunna underlätta arbetet med urvalet av sökande samt hur man skulle kunna motverka den diskriminering som vissa författare samt informanter menar förekommer.

The cv. Brunella is an innovative cultivar that combines crisp lettuce characteristics and lettuce being adapted to Brazilian culture conditions. A cv. Crocantella is also included in this segment. It is considered a vigorous lettuce with high numbers of leaves, heavy, thick and light green. The lettuce cultivation may be performed in different cropping systems they are different from each other in crop management and also in post-harvest handling. These differences often produce lettuces with physical, physico-chemical and sensory differentiated. In this way the objective of this study was to determine the effect of different cropping systems in physical, physicochemical and sensory parameters in lettuce cultivars. For cv. Brunella noted that the plant produced hydroponically provided with larger lettuce leaves. The organic plant increased loss of weight. It was not found statistically significant differences for turgor pressure loss analysis among the three cropping systems.The instrumental analysis color demonstrated that hydroponic lettuce presented lighter green that produced the organic system and higher acidity compared to the other two systems. Not found a statistically significant difference in the measurement of soluble solids and total phenolic compounds among the three cropping systems. The sensory analysis cv. Brunella organic was the one with lowest preference and intention to purchase by the consumer. For cv. Crocantella was found that for conventional lettuce leaf area showed higher, then the hydroponic and organic, with significant difference between them. The sample produced in the organic system had lower leaf area, lower ULA and lower initial fresh and even the loss of weight was significantly higher when compared to the other two cropping systems. There was no significant statistical difference in the turgidity initial values, final and loss of turgor pressure between the samples produced in the three cropping systems. In instrumental analysis of color it was also no statistically significant difference among the three cropping systems. The physicochemical analysis was not statistically significant differences in pH values between samples produced in the three cropping systems.The organic sample obtained highest soluble solids, with difference to the hydroponic system. In the determination titratable acidity and total phenolic compounds was obtained statistically significant differences between the three systems. For titratable acidity hydroponic sample had higher acidity, then the organic sample and the conventional sample, for the determination of total phenolic compounds, organic sample had a higher value, then the hydroponic and conventional. With respect to test preference for cv. Crocantela was no statistical difference between the samples produced in the three cropping systems and the purchase intention test, there was significant difference in purchase intent among the samples produced in hydroponic and organic system, that is, the first was most intent the second purchase. It is concluded cultivation system used for the production of lettuce influence on physical characteristics and physico-chemical plants. In this study it was possible to obtain the sensory characterization of Brunella and Crocantella lettuce cultivars. This manner, studies with these characteristics are crucial as they allow the diagnosis of these differences assisting in obtaining important information from production and post-harvest both for the active professional in the field and the consumer. / No Brasil, há um crescente e promissor mercado que explora as novas cultivares de alface e no segmento crocante as cultivares Brunela e Crocantela são exemplos. A cv. Brunela é uma cultivar inovadora que mescla características da alface crespa e da alface americana sendo adaptada às condições brasileiras de cultivo. A cv. Crocantela também está inserida neste segmento. É considerada uma alface vigorosa com elevado números de folhas, pesadas, espessas e de coloração verde clara. O cultivo de alface pode ser realizado em diferentes sistemas de cultivo sendo eles diferentes entre si, em manejo da cultura e também no manuseio pós-colheita. Estas diferenças, muitas vezes, produzem alfaces com características físicas, físico-químicas e sensoriais diferenciadas. Desta forma, o objetivo deste estudo foi determinar o efeito dos diferentes sistemas de cultivo em parâmetros físico, físico-químicos e sensoriais em cultivares de alface. Para a cv. Brunela observou-se que a planta produzida em sistema hidropônico proporcionou alface com folhas maiores. A planta orgânica obteve maior perda de massa fresca. Não foi constatada diferença estatística significativa para análise de perda de pressão de turgescência entre os três sistemas de cultivo. A análise de cor instrumental demonstrou que a alface hidropônica apresentou verde mais claro que a produzida no sistema orgânico e com maior acidez, quando comparada aos dois outros sistemas. Não constatouse diferença estatística significativa na quantificação dos sólidos solúveis e dos compostos fenólicos totais entre os três sistemas de cultivo. Com relação à análise sensorial a cv. Brunela orgânica foi a que apresentou menor preferência e intenção de compra pelo consumidor. Para a cv. Crocantela verificou-se que para área foliar a alface convencional apresentou maior valor, seguida da hidropônica e da orgânica, com diferença estatística significativa entre elas. A amostra produzida no sistema orgânico obteve menor área foliar, menor AFU e menor massa fresca inicial e, ainda a perda de massa fresca foi significativamente maior quando comparada aos dois outros sistemas de cultivo. Não foi observada diferença estatística significativa nos valores de turgescência inicial, final e perda de pressão de turgescência entre as amostras produzidas nos três sistemas de cultivo. Na análise instrumental de cor também não foi observada diferença estatística significativa entre os três sistemas de cultivo. Nas análises físico-químicas não foi observada diferença estatística significativa nos valores de pH entre as amostras produzidas nos três sistemas de cultivo. A amostra orgânica obteve maior valor de sólidos solúveis, com diferença para o sistema hidropônico. Na determinação de acidez titulável e compostos fenólicos totais obteve-se diferença estatística significativa entre os três sistemas. Para acidez titulável a amostra hidropônica obteve maior acidez, seguida da amostra orgânica e da amostra convencional e, para a determinação de compostos fenólicos totais, a amostra orgânica obteve maior valor, seguida da hidropônica e da convencional. Com relação ao teste preferência para a cv. Crocantela não foi observada diferença estatística entre as amostras produzidas nos três sistemas de cultivo e, no teste de intenção de compra, foi observada diferença significativa na intenção de compra entre as amostras produzidas no sistema hidropônico e orgânico, ou seja, a primeira teve maior intenção de compra que a segunda. Conclui-se o sistema de cultivo utilizado para a produção da alface influencia em características físicas e físico-químicas das plantas. Neste estudo foi possível obter a caracterização sensorial das cultivares de alface Brunela e Crocantela. Desta forma, estudos com estas características são fundamentais, pois permitem o diagnóstico destas diferenças auxiliando na obtenção de informações importantes de produção e pós-colheita tanto para o profissional atuante na área como para o consumidor.

The purpose of the study is to give job seekers a reason that helps with decision making if videoCV is a good option when looking for a job and what to consider when choosing a videoCV to reach out with their message. The Marketing Director of the Security Council has been a supervisor and the study should also be a support for the recruiters at the Security Council when customers show interest in using mobile resumes. Moving CVs can be a good option to increase the ability to get jobs. This is especially true of certain industries, for example media and occupations in service. But the pitfalls are many. It can easily be too much focus on the outer look for those who make their video CV and for recruitment on a video Cv. But, if you use a moving CV correctly, you can easily reach out with your message, for example, make sure references tell about the applicant's positive personalities.

>Magister Scientiae - MSc / HIV and AIDS are among the world's pandemics that pose serious concern to almost every individual in the world. With the current level of availability of anti-retroviral (ARV) drugs and the ease of accessibility of treatment in many countries such as South Africa, the disease can be controlled by suppressing the viral load of an infected individual. These anti HIV drugs such as delavirdine are metabolised by enzymes which are found in the liver microsomes, particularly those of the cytochrome P450 family. Due to the fact that the metabolic rate of a patient determines the effect of the drug, the drug could either have a beneficial or an adverse effect once it is administered. It is therefore imperative that the metabolic profile of a patient is determined at point-of-care is necessary for proper dosing of the ARV drugs. In this project a nanobiosensor system was devised and used for the determination of the metabolism of delavirdine, a non-nucleoside reverse transcriptase inhibitor (NNRTI) ARV drug. The nanobiosensor was prepared by the entrapment of the isoenzyme CYP3A4 into a pre-formed electro active carrier matrice consisting of a dendrimeric copper generation-2 poly (propylene imine)-co-polypyrrole star copolymer (Cu(G2PPI)-co-PPy). The metallo-dendrimer was used as a host for the enzyme and provided thenecessary bio-compatible environment that allowed the direct transfer of electrons between the enzyme's active centres and platinum electrode surface. Copper was the choice of metal used in the study due to its properties. Copper is a malleable, ductile and a good conductor of both heat and electricity. It is a better conductor than most metals. Silver which also belongs to group 1b in the periodic table is a better electrical conductor than copper but copper has better corrosion resistance and is a more abundant and hence it is a cheaper material to use. Cu(G2PPI)-co-PPy was prepared by the incorporation of the copper metal into the G2PPI and the electropolymerization of pyrrole onto the Cu(G2PPI). The incorporation of Cu into G2PPI was determined by FTIR which did not show the presence of the Cu but showed an increase in the intensities of the peaks after the incorporation. The surface morphology of Cu (G2PPI) was confirmed by the use of HRSEM which showed a difference in the surface morphology of the dendrimer moiety with the addition of the copper metal. The HRSEM images after Cu incorporation resulted in the change from rough surface to smooth surface with open cavities which were essential for the entrapment of the biological systems (CYP3A4). Energy dispersive spectrometry (EDS) and HRTEM were used to confirm the presence of spherically shaped copper nanoparticles in the Cu (G2PPI) and were found to have a size distribution of 12-17 nm with an average particle size of 15nm. The star copolymer (Cu(G2PPI)-co-PPy) was characterised using cyclic voltammetrywhere it was confirmed that the material was electroactive and conducting due to electron movement along the polymer chain. A diffusion co-efficient (D₀) value of 8.64 x 10⁻⁵ cm²/s was determined for the material indicating a slow electron transfer kinetics within the diffusion layer. The constructed nanobiosensor was developed using copper poly (propylene imine) – polypyrrole star copolymer, bovine serum albumin and glutaraldehyde coupled to the enzyme CYP3A4. The resultant nanobiosensor parameters include a dynamic linear range (DLR) of 0.01-0.06 nM, a limit of detection (LOD) of 0.025 nM and a sensitivity value of0.379 μA/nM.

A banana é altamente susceptível a injúrias causadas pelo frio, mas o efeito da refrigeração nos atributos que caracterizam a qualidade do fruto maduro é ainda pouco explorado. Neste trabalho, alguns desses atributos foram analisados em duas cultivares de banana escolhidas por sua diferença em relação à susceptibilidade ao frio: Nanicão e Prata. As duas cultivares foram armazenadas a baixas temperaturas (cv. Nanicão a 13 ºC e cv. Prata a 13 ºC e 10 ºC) por 15 dias e o efeito do frio sobre os compostos voláteis responsáveis pelo aroma e sabor, índices de cor da casca, níveis de carotenoides, açúcares e amido foram analisados comparativamente durante a maturação dos frutos e o perfil de proteínas diferentemente abundantes foi analisado na cultivar Nanicão. Com o auxílio das ferramentas da estatística multivariada, verificou-se que a produção dos compostos voláteis é altamente sensível as baixas temperaturas. A cv. Prata apresentou uma maior resistência ao efeito negativo do armazenamento, mesmo armazenada a 10 ºC. Na cv. Nanicão, as amostras maduras do grupo frio (13 ºC) foram caracterizadas pela presença dos carotenoides majoritários devido ao fato de que as vias metabólicas que utilizam carotenoides terem sido afetadas pelo armazenamento em baixas temperaturas. Para a cv. Prata teve um efeito negativo com o armazenamento, com redução dos níveis de carotenoides tanto a 13 ºC quanto a 10 ºC. Em relação à cor da casca dos frutos não foi observado um efeito evidente nas amostras submetidas a baixas temperaturas. Pela análise proteômica, foi possível entender como o frio causou um impacto negativo na síntese de sacarose, uma vez que as proteínas mais afetadas foram associadas ao metabolismo de energia e de carboidratos. / Bananas are fruits highly susceptible to injuries caused by cold temperatures, but the effect of refrigeration on the attributes that characterize the quality of ripe fruit is still underexplored. In this work, some of these attributes were analyzed in two banana cultivars chosen for their difference in susceptibility to cold temperatures: Nanicão and Prata. Both cultivars were stored at low temperatures (cv. Nanicão at 13 ºC and cv. Prata at 13 °C and 10 °C) for 15 days and the effect of the cold on the volatile compounds responsible for aroma, skin color index, levels of carotenoids, sugars, and starch were comparatively analyzed during fruit maturation and different abundant protein profiles of the Nanicão cultivar were analyzed. By using multivariate statistic tools, it was found that the production of volatile compounds is highly susceptible to low temperatures. However, cv. Prata showed greater resistance to the negative effects of storage even when stored at 10 °C. For cv. Nanicão, ripe samples from the cold group kept at 13 ºC were characterized by the presence of majority carotenoids due to the fact that the metabolic pathways that use carotenoids were affected by the storage at such a low temperature. Conversely, cv. Prata experienced a negative effect with the storage, with reduced levels of carotenoids in both cold groups kept at 13 ºC and 10 ºC. In relation the skin color of the fruit, no effect on the samples held at low temperatures was observed. For proteomics analysis, it was possible to understand how the cold storage caused a negative impact on the synthesis of sucrose, since most of the affected proteins were associated with energy and carbohydrate metabolism.

Os materiais de referência certificados (MRCs) desempenham importante papel na obtenção de resultados de medições rastreáveis ao Sistema Internacional de Unidades (SI), por meio de uma cadeia contínua de comparações. Dessa forma, a demanda por novos materiais de referência certificados (MRC) aumenta a cada dia em todas as áreas do conhecimento. A disponibilidade de materiais de referência, principalmente no Brasil, ainda é incipiente, face a demanda que excede em muito a variedade disponível desses materiais. Entre as diversas áreas carentes de materiais de referência, destaca-se a área de alimentos pela importância desses produtos na balança comercial do país. A certificação de produtos alimentícios, destinados tanto para exportação como para o consumo interno, requer metodologias de análise que ofereçam resultados precisos e exatos a fim de assegurar a qualidade do produto. Este trabalho descreve a produção e certificação de um material de referência na matriz peixe em mercúrio e metilmercúrio. O estudo reúne desde a etapa de seleção do material, preparação, desenvolvimento dos estudos de homogeneidade e estabilidade e a caracterização. A certificação foi realizada por meio de medições utilizando duas técnicas analíticas, a Espectrofotometria de Absorção Atômica (AAS) com sistema de injeção em fluxo e geração de vapor frio (FIA-CV-AAS) e a Diluição Isotópica aplicada a Espectrometria de Massas (IDMS), sendo este um método primário. Neste trabalho as normas da série ISO 30 (ABNT 3034) e ISO Guide 35 foram utilizadas como base para a preparação e caracterização do material. Para o cálculo de incertezas foi utilizado o GUM e o guia Eurachem. Como resultado, foi produzido e certificado um lote do material em relação ao teor de mercúrio (Hg = 0,271±0,057 μg g-1) e metilmercúrio (MeHg = 0,245±0,038 μg g-1), além de valores informativos de chumbo e arsênio. / The certified reference materials (CRMs) play an important role in obtaining measurement results traceable to the International System of Units, through an unbroken chain of comparisons. Thus, the demand for new certified reference materials (CRMs) increases every day in all areas of knowledge. The availability of reference materials, mainly in Brazil is still incipient, given that the demand far exceeds the available variety of these materials. The amount of certified reference materials available in the country is insufficient to meet the need of the scientific community and demands for development of new methodologies. Among the many areas in need of reference materials, we highlight the importance for the food trade balance for these products within the country. The certification of food products, intended both for export and for domestic consumption, requires analysis methods that provide precise and accurate results to ensure product quality. This paper describes the preparation and certification of a reference material in the fish matrix in mercury and methylmercury. The study brings together since the stage of material selection, preparation, development of homogeneity and stability studies and characterization. The certification was performed by means of measurements using two analytical techniques, flow injection analysis - cold vapor atomic absorption spectrometry (FIA-CV-AAS) and isotope dilution applied to mass spectrometry (IDMS), which is a primary method. In this work the standards of the ISO 30 (ABNT 30-34) and ISO Guide 35 was used as the basis for the preparation and characterization of the material. For the calculation of uncertainties was used the GUM and Eurachem guide. As a result, was produced and certified a lot of material in relation to the concentration of mercury (Hg = 0.271 ± 0.057 mg g-1) and methylmercury (MeHg = 0.245 ± 0.038 mg g-1), and informational values of lead and arsenic .

Diese Dissertation untersucht individuelle Unterschiede in der Adaptation von Jugendlichen und fokussiert auf jugendliche Immigranten. Sie postuliert ein übergreifendes Rahmenmodell, das entwicklungs-, akkulturations-, und intergruppenpsychologische Ansätze integriert, um ein umfassendes Verständnis der Adaptationsprozesse zu erlangen. Von diesem Rahmenmodell werden zwei Forschungsfragen abgeleitet. Die erste Frage lautet, wie ist das Zusammenspiel von Entwicklungs- und Akkulturationsaufgaben? Die zweite Frage lautet, wie ist das Zusammen-spiel dieser Aufgaben mit den Beziehungen zu der Familie und den Gleichaltrigen? Die Dissertation basiert auf drei empirischen Studien, die längsschnittliche Daten von Schülern mit und ohne Migrationshintergrund verwendeten. Studie 1 zeigte, dass eine gut funktionierende Familie und die Beteiligung an der Herkunfts- und Aufnahmekultur Selbstwirksamkeitserwartungen und ethnische Identität vorhersagten. Studie 2 ergab, dass soziometrische Beliebtheit in der In- aber nicht der Outgroup Selbstwert von Jugendlichen vorhersagte, was durch selbstwahrgenommene Beliebtheit mediiert wurde. Studie 3 zeigte, dass soziometrische Beliebtheit bei Klassenkameraden ohne, aber nicht bei solchen mit, Migrationshintergrund ein geringes persönliches Diskriminationserleben in jugendlichen Migranten vorhersagte. Zusammenfassend hat diese Dissertation das Rahmenmodell erfolgreich angewendet, in dem sie gezeigt hat, dass positive Beziehungen mit der Familie und Gleichaltrigen Ressourcen für das Bewältigen von Entwicklungs- und Akkulturations-aufgaben darstellten, die miteinander verwoben waren. Die wesentliche Implikation ist, dass jede der beiden Kulturen und sozialen Gruppen eine Quelle unterschiedlicher Risiken und Ressourcen ist, die alle wichtige Aspekte der Adaptation sind. Diese Dissertation ist ein wichtiger Schritt in Richtung eines kontextualisierten und integrativen Verständnisses der Adaptation von Jugendlichen in einer modernen Gesellschaft. / This dissertation examines individual differences in the adaptation of adolescents and focuses on the case of immigrant adolescents. It proposes a guiding framework that integrates developmental, acculturative, and intergroup approaches in order to achieve a comprehensive understanding of the processes underlying adaptation. From this framework, I derive two core research questions that guide the three empirical studies of this dissertation. First, what is the longitudinal interplay of developmental tasks and acculturative tasks? Second, what is the longitudinal interplay of either of these two tasks and the quality of adolescents’ relationships with family and peers? This dissertation is based on three studies that used the same longitudinal data set of immigrant and host-national students. Study 1 showed that family functioning and involvement in host and ethnic cultures predicted immigrant adolescents’ self-efficacy and ethnic identity. Study 2 revealed that sociometric peer likability by ingroup but not outgroup classmates predicted self-esteem of both immigrants and host-nationals, which was fully mediated by their self-perceived likability. Study 3 demonstrated that sociometric peer likability by host-national but not by immigrant classmates predicted low perceptions of personal discrimination in immigrant adolescents. In summary, this dissertation successfully applied the proposed integrative framework by demonstrating that positive relationships with family and peers represented resources for adolescents’ mastery of their acculturative and developmental tasks, which in turn were intertwined. The main implication is that each of the two cultures and societal groups presents immigrant adolescents with different risks and resources that are all important aspects of their adaptation. In sum, this dissertation is an important step toward a more contextualized and integrative understanding of the adaptation of adolescents in a modern society.
