Eight mature Holstein and Jersey cows beginning their third or later lactation were used throughout this study to evaluate various aspects of the lactation cycle. The lactation (control) diet consisted of 28.8% corn silage, 22.4% alfalfa haylage, and 48.8% concentrate dry matter. Breeds responded differently to the stress of calving. Jerseys had higher plasma somatotropin on day after calving, but Holsteins had higher glucose on day of and day after calving. Plasma parathyroid hormone did not differ between breeds, but Jerseys had higher 1,25-dihydroxyvitamin D₃ than Holsteins on both days after calving. Plasma total calcium and ionized calcium concentrations were lower for Jerseys on both days. Holsteins and Jerseys had similar concentrations of hormones and calcium at 4 and 8 wk. Ionized calcium as a percent of total calcium was elevated at calving, as compared to other times in the lactation cycle, in both breeds. From 9 to 21 wk, 4 of 8 Holsteins and 4 of 8 Jerseys were fed a diet supplemented with tallow. Holsteins fed tallow had lower somatotropin than Holsteins fed control diet at 14 and 18 wk. Plasma glucose, parathyroid hormone, and 1,25-dihydroxyvitamin D₃ were similar between tallow- and control-fed cows in both breeds. Plasma total calcium and ionized calcium were higher at 20 wk for Holsteins and Jerseys fed tallow. Dry matter intake was not influenced by diet in either breed. However, Holsteins, but not Jerseys, fed tallow produced more milk and higher body weights than Holsteins fed the control diet. Balance trials results indicated dietary tallow addition increased energy intake, energy digestibility, and metabolizable energy, but it decreased partial efficiency of metabolizable energy utilization for lactation. Although digestibility of calcium and magnesium was unchanged, tallow-fed cows were in greater positive calcium and magnesium balance than control-fed cows. Stage of lactation had little effect on specific gravity, shear stress, percent mineral, and histological measurements of biopsied rib samples. However, Jersey rib had higher specific gravity than Holstein rib. All cows had similar bone histological features throughout lactation. / Ph. D.

Au cours des dernières années, la production laitière a été en croissance constante en raison de plusieurs facteurs tels que l’utilisation d’individus plus performants. L’augmentation du nombre d’enregistrements de vaches de la race Jersey confirme l’intérêt économique des producteurs pour cette race en raison de la production élevée de protéines et de gras du lait par rapport aux autres races. Cependant, les embryons de la race Jersey ont montré des difficultés dans le processus de cryopréservation lequel peut aider à une commercialisation massive de matériel génétique de cette race. Il a été observé que la race Jersey présente un faible taux de gestation lors du transfert des embryons après la cryopréservation en comparaison aux embryons de la race Holstein. Nous proposons que cette différence entre les deux races bovines soit due à des caractéristiques spécifiques de la race au niveau du phénotype et du génome. Dans un premier temps, les résultats de cette étude ont mis en évidence des différences au niveau du phénotype et du profil lipidique et génomique de l’embryon Jersey. Celui-ci est caractérisé par un contenu de lipides associé à une faible fonction mitochondriale laquelle déterminera le faible succès à la cryopréservation. Par la suite, nous avons évalué au niveau du phénotype et de la génomique, l’utilisation de la L-carnitine dans le milieu de culture in vitro afin de compenser cette caractéristique des embryons de la race Jersey. Cette étude sur la supplémentation de L-carnitine a permis d'identifier une faible réponse chez les embryons Jersey qui est expliqué par le faible effet de la L-carnitine sur l’activité mitochondriale. Afin de définir l’impact de la fonction mitochondriale sur la viabilité de l’embryon lors de nos études, nous avons mis au point une méthode pour compenser la dysfonction mitochondriale sur le développement embryonnaire chez le bovin. Enfin, l’application de la vitamine K2 dans le milieu de culture in vitro montre un impact positif sur la fonction mitochondriale qui a mené à des changements phénotypiques et génomiques chez les embryons bovins. En conclusion, ce projet a permis de caractériser et d’identifier la race comme un facteur qui limite la cryopréservation des embryons et peut influencer sur le métabolisme embryonnaire au niveau des mitochondries. La fonction mitochondriale est une caractéristique importante sur le développement embryonnaire bovin qui peut ouvrir sur des perspectives d’amélioration de la viabilité embryonnaire. / For the past decades, milk production has been increasing due to several factors such as the use of high genetic merit individuals. In this regard, Jersey cows have been of interest for the producers because of high protein and fat indexes in their milk compared to others breeds. However, there are some challenges associated with Jersey particularly poor results using embryo cryopreservation which could help to massively commercialize the genetic material of this breed. It was observed that the Jersey breed have low pregnancy rates following embryo transfer of cryopreserved Jersey embryos compared to the Holstein breed. Here, we hypothesised that those differences between these two breeds in embryo cryopreservation are due to specific phenotypic and genotypic characteristics at the embryo level. Initially, the results of this study showed differences on the phenotype, lipid profile and genomic differences of Jersey embryo characterized by the higher lipid droplets content associated with low mitochondrial function which will determine the low success with cryopreservation. Subsequently, we assessed the phenotype and genotype of embryos using L-carnitine supplementation in the in vitro embryo culture medium in order to compensate those characteristics in Jersey embryos. The results of this study revealed moderate beneficial effects of L-carnitine supplementation in Jersey embryos through low effect of L-carnitine on mitochondrial activity. To define the impact of mitochondrial function on the embryo viability during our study, we developed a method to compensate the mitochondrial dysfunction during early embryo development in bovine model. To do that, Vitamin K2 supplementation in the in vitro embryo culture medium was applied which showed a positive effect on the mitochondrial function leading to satisfactory phenotypic and genotypic changes in the embryos. In conclusion, this study resulted in identification and characterization of the cattle breeds effects as a critical factor on cryopreservation performance and embryonic metabolism of the mitochondria. Our results emphasized that mitochondrial function is an important feature of embryonic development in cattle, which can provide opportunities to improve embryonic viability.

[pt] Os trabalhos de Richard Serra e Robert Smithson apresentamuma relação constituitiva com o espaço público da megalópole contemporânea. Explorando a noção de tempo específico da matéria, suas produções expandem a concepção de processo artístico e criam uma tensão com a arquitetura e o espaço institucional da arte. Ao propor a crítica a estes espaços e explorar o mundo, ambas as obras estabelecem um jogo de semelhança com a megalópole, incorporando a racionalidade de seu espaço ético, político e cultural. Para tal, considero a relação com a Nova York laboratorial na qual Serra e Smithson desenvolvem intenso debate com seus pares, relação constitutiva que aconteceu com e na caótica Manhattan do final dos anos de 1960, bem como nas áreas suburbanas de New Jersey. Smithson constrói sua obra tendo a entopia do subúrbio de new Jersey como referência determinante, a partir da qual tempos e espaços infinitos são trazidos às suas realizações. O embate de Serra com a cidade assume por sua vez um caráter concreto e literal. Trabalhando no próprio caos e nas ruínas contemporâneas da urbe, ele propõe uma nova relação entre obra, o espectador e o entorno. Em ambos os artistas encontrados o esforço do largamento do conceito da escultura contemporânea numa nova relação como mundo. / [en] The works os Richard Serra and Robert Smithson have a founding relationship with the public space of the contemporary megalopolis. By incorporating the notion of the specific time of material, their output expands conceptions of the artistic process and sets up a tension with architecture and the institutional space of art. As they propose to criticize institutional space and explore the word, the works set a play of similarities with the megalopolis, incorporating the rationale of its ethical, political and cultural space. I therefore investigate the relationship with the New York laboratory where Serra and Smithson engage in intense debate with their peers. This founding relationship was formed in and through the bustling Manhattan of the late 1960s and suburban areas of new Jersey. The decisive reference for Smithson s work was the entropy of the New Jersey suburb, from which infinite times and spaces are brought into his work. Serra s clash with the city is concrete and literal in nature. Working in the midst of the chaos and contemporary ruins of the city, he proposes a new relationship between the work, the spectator and the surroundings. There are elements in both artists that strive to broaden the concept of contemporary sculpture in a new relationship with the world.

Children detained in juvenile detention centers in the United States are a unique population. They are neither incarcerated, nor are they free to live in society. Although some popular literature does exist on juvenile detention, such literature is minimal. Further, there are few research studies on this population in any field of inquiry. Indeed the entire subject of juvenile detention has been largely overlooked by research scientists, as well as theologians. The focus of this empirical study is the theology and spirituality of children in a single juvenile detention center in New Jersey, US. Currently, there are no studies on this topic. This study begins to address that void and represents the first theological research of its kind on this population. The methodological approach of the thesis is multi-disciplinary. While the study addresses theology and spirituality as separate categories, it also integrates theology with research in psychology and clinical mental health. The project itself consists of 200 individual, face-to-face interviews with male juvenile residents detained in the Ocean County Juvenile Detention Center, Toms River, New Jersey, US. An original questionnaire has been developed by the author as a research tool. This empirical research adds to the academic literature on children in juvenile detention centers in the United States and recommends ways that staff may communicate with children to begin a theological dialogue. Further, this thesis offers a specific methodology and research tool to be duplicated for use in other juvenile detention centers toward working with children in a concrete, evidence-based, spiritual context. v This study also includes a chapter on the evolution of the author’s spirituality and theology in the course of the project and attempts to locate the self of the researcher within the study. Finally, this thesis presents an outline for a new hermeneutic in working with children in a juvenile detention setting. This new approach represents a practical step toward bridging an existing gap between a stated need for a new hermeneutic for working with children in theological literature and its inception. / Philosophy, Practical and Systematic Theology / D.

The reported number of hate crimes in New Jersey continues to remain high despite the enforcement of laws against perpetrators. The purpose of this correlational panel study was to test Shaw & McKay's theory of social disorganization by examining the relationship between demographic diversity and hate crime rates. This study focused on analyzing the relationship between the level of diversity, residential mobility, unemployment, family disruption, proximity to urban areas, and population density in all 21 New Jersey counties and hate crime rates. The existing data of Federal Bureau of Investigations' hate crime rates and the U.S. Census Bureau's demographic diversity, operationalized as the percentage of Whites over all other races, and social disorganization from 21 between the years 2007 through 2011, for a total sample size of 105 cases of reported hate crimes. Results of the multiple linear regression analysis indicate that ethnic diversity did not significantly predict hate crimes (p = 0.81), residential mobility (p < 0.001), and population density (p < 0.001) had positive effects on hate crime rates. Concentrated disadvantage (p = 0.01), characterized by the number of reported unemployment rates, had a negative effect on hate crime rates. The results of the study supported social disorganization theory in reference to residential mobility and population density. Law enforcement agencies can use the results of this study to combat hate crimes in areas with a high level of residential mobility and population density.

African American women are 18 times more likely to contract HIV than are European American women, yet they are less likely to be tested for HIV. Lack of HIV testing leads to late diagnosis and increased mortality from HIV-related illnesses. Based on the health belief model, this correlational study analyzed the extent to which HIV stigma mediated the relationship between perceived benefits or perceived severity of HIV and the uptake of HIV testing among African American women in New Jersey. A total of 93 African American women aged 18 and older who resided in New Jersey completed online questionnaires. Data were gathered via the Perceptions of Stigmatization by Others for Seeking Help (PSOSH) scale, the Benefits of HIV Testing Scale, and the Severity of HIV Infection Scale. Although there was a relationship between stigma and perceived severity of HIV, this relationship did not translate into uptake of HIV testing. Perceived benefits of HIV testing did show an impact on uptake. Based on the findings of this study, research and intervention programs should concentrate on the potential benefits of HIV testing among African American women. Through dissemination of these findings, positive social change that may result through increased rates of HIV testing in this population and ultimately better health outcomes for patients who have HIV. Additionally, the findings on HIV benefits could be used as supporting data for policymakers to improve HIV/AIDS prevention programs aimed at African American women by emphasizing the benefits of testing.
