Two molecular epidemiological studies were conducted to examine associations between genetic variation and risk of squamous cell carcinoma of the head and neck (SCCHN). In the first study, we hypothesized that genetic variation in p53 response elements (REs) may play roles in the etiology of SCCHN. We selected and genotyped five polymorphic p53 REs as well as a most frequently studied p53 codon 72 (Arg72Pro, rs1042522) polymorphism in 1,100 non-Hispanic White SCCHN patients and 1,122 age-and sex-matched cancer-free controls recruited at The University of Texas M. D. Anderson Cancer Center. In multivariate logistic regression analysis with adjustment for age, sex, smoking and drinking status, marital status and education level, we observed that the EOMES rs3806624 CC genotype had a significant effect of protection against SCCHN risk (adjusted odds ratio= 0.79, 95% confidence interval =0.64–0.98), compared with the -838TT+CT genotypes. Moreover, a significantly increased risk associated with the combined genotypes of p53 codon 72CC and EOMES -838TT+CT was observed, especially in the subgroup of non-oropharyneal cancer patients. The values of false-positive report probability were also calculated for significant findings. In the second study, we assessed the association between SCCHN risk and four potential regulatory single nucleotide polymorphisms (SNPs) of DEC1 (deleted in esophageal cancer 1) gene, a candidate tumor suppressor gene for esophageal cancer. After adjustment for age, sex, and smoking and drinking status, the variant -606CC (i.e., -249CC) homozygotes had a significantly reduced SCCHN risk (adjusted odds ratio = 0.71, 95% confidence interval = 0.52–0.99), compared with the -606TT homozygotes. Stratification analyses showed that a reduced risk associated with the -606CC genotype was more pronounced in subgroups of non-smokers, non-drinkers, younger subjects (defined as ≤ 57 years), carriers of TP53 Arg/Arg (rs1042522) genotype, patients with oropharyngeal cancer or late-stage SCCHN. Further in silico analysis revealed that the -249 T-to-C change led to a gain of a transcription factor binding site. Additional functional analysis showed that the -249T-to-C change significantly enhanced transcriptional activity of the DEC1 promoter and the DNA-protein binding activity. We conclude that the DEC1 promoter -249 T>C (rs2012775) polymorphism is functional, modulating susceptibility to SCCHN among non-Hispanic Whites. Additional large-scale, preferably population-based studies are needed to validate our findings.^

Hispanics form the second-largest minority group in the United States totaling 22 million people. Health data on this population are sparse and inconsistent. This study seeks to determine use of preventative services and risk factor behaviors of Mexican American and non-Hispanic White females residing in South Texas.^ Baseline data from female respondents in household surveys in six South Texas counties (Ramirez and McAlister, 1988; McAlister et al., 1992) were analyzed to test the following hypotheses: (1) Mexican American and Non-Hispanic White females exhibit different patterns of health behaviors; (2) Mexican American females will exhibit different health behaviors regardless of age; and (3) the differences between Mexican American women and non-Hispanic White females are due to education and acculturation factors.^ Over the past decade, the traditional behaviors of Mexican American females have begun to change due to education, acculturation, and their participation in the labor force. The results from this study identify some of the changes that will require immediate attention from health care providers. Results revealed that regardless of ethnicity, age, education, and language preference, non-Hispanic White females were significantly more likely to participate in preventive screening practices than were Mexican American females. Risk factor analysis revealed a different pattern with Mexican American females significantly more likely to be non-smokers, non-alcoholic drinkers, and to have good fat avoidance practices compared to non-Hispanic White females. However, compared to those who are less-educated or Spanish-speaking, Mexican American females with higher levels of education and preference for speaking English only showed positive and negative health behaviors that were more similar to the non-Hispanic White females. The positive health behaviors that come with acculturation, e.g., more participation in preventive care and more physical activity, are welcome changes. But this study has implications for global health development and reinforces a need for "primordial" prevention strategies to deter the unwanted concomitants of economic development and acculturation. Smoking and drinking behaviors among Mexican American females need to be kept at low levels to prevent increased morbidity and premature deaths in this population. ^

In view of the drastic growth in the Canadian Inuit population, the rising costs of living, the missing job and income alternatives and the high unemployment rate in the arctic, efforts are being made to make use of the muskox populations in order to provide additional sources of food and/or revenue. The present paper attempts to review the course of muskox utilization in the Canadian Arctic and to tentatively assess its present as weIl as its future economic importance. Starting with the pre-European status of muskoxen in Canada, the drastic reduction in numbers resulting from the combined efforts of hide traders, whalers and expedition parties in the 19th and early 20th centuries, the impact of the legal protection and the recovery since 1917 are being described. Establishing muskox farms with semi-domesticated herds failed in Canada in the 1970's. Since 1969, though, increasing numbers of animals have been allotted to many Inuit communities, and despite the fact that most of the animals were primarily used for subsistence purposes, some communities could reserve part of their quotas for trophy (sport) hunters. While controlled sustainable subsistence and trophy hunts may eventually be carried out over the whole muskox range, including recently colonized northern Quebec, commercial harvesting for meat, hides and wool, introduced in 1981, will at least for some time be restricted to Banks and Victoria islands which at present show 78 % of the Canadian muskox population and 94 % of the overall quota.

From its humble beginnings as a small workshop established by Tomáš Baťa in 1874, the Bata Shoe Company became a gigantic concern in the 1920s, built on the principles of scientific management and welfare capitalism. The growth of the company engulfed Zlín (in today’s Czech Republic), its hometown, and transformed it into a modern industrial garden city satisfying the needs of both a growing industrial population, and those of the company itself. As a reaction to the aftermath of the crisis of 1929, the enterprise began a strategy of decentralization and international expansion characterized by the design and construction of a series of modern industrial towns that replicated the model of Zlín around the globe. This study is an exhaustive survey of these cities, their rationale, design, and their postindustrial conditions; it is a comparative work that has used field trips, photography, interviews, and archival material to explain the logics behind Bata’s project, to document the design and implementation of the model to multiple contexts and geographies, and to evaluate of the urban legacy of this undertaking. Finally, the research explores the question of what can the design disciplines, and other parties involved, learn from a full synthesis on the history and urbanism of the Bata satellite cities with regard to the re-imagination and sustainability of contemporary industry-sponsored interventions in developing geographies. RESUMEN Con origen en un humilde y pequeño taller fundado en 1874 por Tomáš Baťa, la Bata Shoe Company creció hasta convertirse en una gigantesca empresa en los anos 20, fundada en principios de control científico de la producción y capitalismo de bienestar. El crecimiento de la compañía se extendió por Zlín (en la actual República Checa), su pueblo de nacimiento, y la transformó en una moderna ciudad jardín industrial capaz de satisfacer las necesidades tanto de una población en alza como de la propia empresa. Como reacción a la crisis de 1929, Bata inició una estrategia de descentralización y expansión internacional caracterizada por el proyecto y construcción de modernas ciudades industriales que replicaron el modelo de Zlín por el mundo. Esta tesis es un estudio exhaustivo de estas ciudades: las razones detrás del proyecto, su diseño, y su condición post-industrial; es un estudio comparativo que se ha servido de trabajo de campo, documentación fotográfica, entrevistas y materiales de archivo para explicar la lógica detrás del proyecto de Bata, documentar el diseño e implementación de tal modelo en múltiples contextos y geografías, y valorar el legado urbano de esta empresa. Finalmente, la investigación evalúa qué podrían aprender las disciplinas del diseño y otras partes implicadas de una síntesis completa de la historia y el urbanismo de las ciudades satélite de Bata, en lo relativo a la reinvención y sostenibilidad de proyectos contemporáneos de la industria en geografías en desarrollo.

From pharmacological studies using histamine antagonists and agonists, it has been demonstrated that histamine modulates many physiological functions of the hypothalamus, such as arousal state, locomotor activity, feeding, and drinking. Three kinds of receptors (H1, H2, and H3) mediate these actions. To define the contribution of the histamine H1 receptors (H1R) to behavior, mutant mice lacking the H1R were generated by homologous recombination. In brains of homozygous mutant mice, no specific binding of [3H]pyrilamine was seen. [3H]Doxepin has two saturable binding sites with higher and lower affinities in brains of wild-type mice, but H1R-deficient mice showed only the weak labeling of [3H]doxepin that corresponds to lower-affinity binding sites. Mutant mice develop normally, but absence of H1R significantly increased the ratio of ambulation during the light period to the total ambulation for 24 hr in an accustomed environment. In addition, mutant mice significantly reduced exploratory behavior of ambulation and rearings in a new environment. These results indicate that through H1R, histamine is involved in circadian rhythm of locomotor activity and exploratory behavior as a neurotransmitter.

For nearly 200 years since their discovery in 1756, geologists considered the zeolite minerals to occur as fairly large crystals in the vugs and cavities of basalts and other traprock formations. Here, they were prized by mineral collectors, but their small abundance and polymineralic nature defied commercial exploitation. As the synthetic zeolite (molecular sieve) business began to take hold in the late 1950s, huge beds of zeolite-rich sediments, formed by the alteration of volcanic ash (glass) in lake and marine waters, were discovered in the western United States and elsewhere in the world. These beds were found to contain as much as 95% of a single zeolite; they were generally flat-lying and easily mined by surface methods. The properties of these low-cost natural materials mimicked those of many of their synthetic counterparts, and considerable effort has made since that time to develop applications for them based on their unique adsorption, cation-exchange, dehydration–rehydration, and catalytic properties. Natural zeolites (i.e., those found in volcanogenic sedimentary rocks) have been and are being used as building stone, as lightweight aggregate and pozzolans in cements and concretes, as filler in paper, in the take-up of Cs and Sr from nuclear waste and fallout, as soil amendments in agronomy and horticulture, in the removal of ammonia from municipal, industrial, and agricultural waste and drinking waters, as energy exchangers in solar refrigerators, as dietary supplements in animal diets, as consumer deodorizers, in pet litters, in taking up ammonia from animal manures, and as ammonia filters in kidney-dialysis units. From their use in construction during Roman times, to their role as hydroponic (zeoponic) substrate for growing plants on space missions, to their recent success in the healing of cuts and wounds, natural zeolites are now considered to be full-fledged mineral commodities, the use of which promise to expand even more in the future.

This EPIN study brings together contributions from a broad selection of member states and provides insightful analysis into the 2014 elections to the European Parliament on the ground. The report reveals the different factors that impede the development of genuine European elections and the consequences of the ballot in the member states covered by the study, namely Bulgaria, Finland, France, Germany, Greece, Italy, the Netherlands, Poland, Romania, Spain and the UK, and at EU level. The report finds that: • The EP Resolution to encourage European parties to nominate candidates for the next Commission President has not really increased public interest in the EU and voter turnout will probably remain low. • Visibility of the European top candidates in most member states has been quite limited. • National manifestos do not coincide – and sometimes event conflict with – the European parties’ manifestos. • Election debates focus on national issues; EU issues are only brought to public debate when they are relevant for domestic politics. • Again, we will see a protest vote against governments and large parties. The EP elections are still perceived as a test ahead of local and national elections, or as a vote of confidence in national governments. • This year the protest vote also concerns the EU. The report predicts a more eurosceptic ballot that might complicate decision-making in the EU, exacerbate the conflict between the national and European levels and increase tensions among member states.

Overview. Questions about the interface between the multilateral climate regime embodied in the Kyoto Protocol and the multilateral trade regime embodied in the World Trade Organisation (WTO) have become especially timely since the fall of 2001. At that time, ministerial-level meetings in Marrakech and Doha agreed to advance the agendas, respectively, for the implementation of the Kyoto Protocol and for negotiations on further agreements at the WTO. There have been concerns that each of these multilateral arrangements could constrain the effectiveness of the other, and these concerns will become more salient with the entry into force of the Kyoto Protocol. There are questions about whether and how the rights and obligations of the members of the WTO and the parties to the Protocol may conflict. Of particular concern is whether provisions in the Protocol, as well as government policies and business activities undertaken in keeping with those provisions, may conflict with the WTO non-discrimination principles of national treatment and most-favoured nation treatment. The WTO agreements that are potentially relevant to climate change issues include many of the individual Uruguay Round agreements and subsequent agreements as well. The principal elements of the Kyoto Protocol that are particularly relevant are its provisions concerning emissions trading, the Clean Development Mechanism, Joint Implementation, enforcement, and parties’ policies and measures. In combination, therefore, there are numerous potential points of intersection between the elements of the Kyoto Protocol and the WTO agreements. Previous studies have clarified many issues, as they have focused on particular aspects of the regimes’ relationships. Yet, some analyses suggest that the two regimes are largely compatible and even mutually reinforcing, while others suggest that there are significant conflicts between them. Those and other studies are referenced in the ‘suggestions for further reading’ section at the end of the paper.1 The present paper seeks to expand on those studies by providing additional breadth and depth to understanding of the issues. The analysis gives special attention to key issues on the agenda – i.e. issues that are particularly problematic because of the likelihood of occurrence of specific conflicts and the significance of their economic and/or political consequences. The paper adopts a modified ‘triage’ approach, which classifies points of intersection as (a) highly problematic and clearly in need of further attention, (b) perhaps problematic but less urgent, and (c) apparently not problematic, at least at this point in time. The principal conclusions are that: · The missions and objectives of the two regimes are largely compatible, and their operations are potentially mutually reinforcing in several respects. · Some provisions of the multilateral agreements that may superficially seem at odds are not likely to become particularly problematic in practice. · ‘Domestic policies and measures’ that governments may undertake in the context of the Protocol could pose difficult issues in the context of WTO dispute cases. · Recent WTO agreements and dispute cases acknowledge the legitimacy of the ‘precautionary principle’ and are thus consistent with the environmental protection objectives of the Protocol. · The relative newness of the climate regime creates opportunities for institutional adaptation, as compared with the constraints of tradition in the trade-investment regime. · The prospect of largely independent evolutionary paths for the two regimes poses a series of issues about future international regime design and management, which may require new institutional arrangements. In sum, the present paper thus finds that although there are some areas of interaction that are problematic, the two regimes may nevertheless co-exist in relative harmony in other respects –more like ‘neighbours’ than either ‘friends’ or ‘foes’, as Krist (2001) has suggested.

Ethnicity and ethnic parties have often been portrayed as a threat to political stability. There is also no shortage of conflicts with an ethnic flavor. Yet, this book challenges the notion that the organization of politics in heterogeneous societies should necessarily overcome ethnicity. Rather, descriptive representation of ethnic groups arguably has potential to increase regime support and reduce conflict. The book studies partisan-descriptive representation of up to 130 ethnic groups in central and eastern European democracies. Ethnic minority parties are found to only run and succeed if they can expect electoral support sufficient to pass the electoral threshold. Conditional on gender and strategies of representation, ethnic representation increases satisfaction with democracy among the minority population. While protest rises given moderate levels of representation, it is reduced once ethnic groups have access to executives. In conclusion, a proportional vision of power-sharing between ethnic groups receives some qualified empirical support.
The pragmatics of computer-mediated communication between South African and Mexican drug traffickers

South Africa and Mexico are ripe with drug trafficking. The gangs and syndicates running the drug businesses in these two countries collaborate occasionally. Communication between these international drug business partners takes place on social media. Their main language of communication is English, mixed with some limited use of Spanish and Afrikaans. The key purpose of the interactions between the South African and Mexican parties is the organisation of their business activities. This study aims at examining how the drug traffickers position each other and themselves regarding their common business interest and how their relationship evolves throughout their interactions. Moreover, it is of interest to look at how these people make use of different social media and their affordances. For this a qualitative analysis of the interaction between two drug traffickers (one South African and one Mexican) on Facebook, Threema and PlayStation 4 was performed. Computer-mediated communication between these two main informants was studied at various stages of their relationship. Results show that at first the interaction between the South African and Mexican drug traffickers consists of interpersonal negotiations of power. The high risk of the drug business and gang/syndicate membership paired with intercultural frictions causes the two interlocutors to be extremely cautious and at the same time to mark their position. As their relationship develops and they gain trust in each other a shift to interpersonal negotiations of solidarity takes place. In these discursive practices diverse linguistic strategies are employed for creating relational effects and for positioning the other and the self. The discursive activities of the interactants are also identity practices. Thus, the two drug traffickers construct identities through these social practices, positioning and their interpersonal relationship.

Since the landmark contributions of Homer Smith and co-workers in the 1930s there has been a considerable advance in our knowledge regarding the osmoregulatory strategy of elasmobranch fish. Smith recognised that urea was retained in the body fluids as part of the 'osmoregulatory ballast' of elasmobranch fish so that body fluid osmolality is raised to a level that is iso- or slightly hyper-osmotic to that of the surrounding medium. From studies at that time he also postulated that many marine dwelling elasmobranchs were not capable of adaptation to dilute environments. However, more recent investigations have demonstrated that, at least in some species, this may not be the case. Gradual acclimation of marine dwelling elasmobranchs to varying environmental salinities under laboratory conditions has demonstrated that these fish do have the capacity to acclimate to changes in salinity through independent regulation of Na+, Cl- and urea levels. This suggests that many of the presumed stenohaline marine elasmobranchs could in fact be described as partially euryhaline. The contributions of Thomas Thorson in the 1970s demonstrated the osmoregulatory strategy of a fully euryhaline elasmobranch, the bull shark, Carcharhinus leucas, and more recent investigations have examined the mechanisms behind this strategy in the euryhaline elasmobranch, Dasyatis sabina. Both partially euryhaline and fully euryhaline species utilise the same physiological processes to control urea, Na+ and Cl- levels within the body fluids. The role of the gills, kidney, liver, rectal gland and drinking process is discussed in relation to the endocrine control of urea, Na+ and Cl- levels as elasmobranchs acclimate to different environmental salinities.
