Despite a significant expansion of the literature on conflicts and fragility of states, only a few systematic attempts have been made to link the theoretical literature on social conflicts to the available micro-level information about the people who are involved in these conflicts. We address this lacuna in the literature using a household-level data set from Kosovo. Our analysis suggests that it is individually rational for competing ethnic communities, Kosovar Albanians and Kosovar Serbs, to resist a quick agreement on a social contract to share the region's resources.

Kosovo is a war-torn corner of the former Yugoslavia, where a civil war between ethnic Albanians and ethnic Serbs raged during most of the 1990s. We examine the incidence and depth of poverty and some of its correlates in post-conflict Kosovo using the Living Standards Measurement Survey.

Using the Living Standards Measurement Study (LSMS) household survey from post-conflict Kosovo, we investigate the comparative economic well-being of Serbs and Albanians. An Oaxaca decomposition shows Serb households are both better endowed with income generating characteristics, such as education, and receive higher returns to these characteristics than Albanian households. Despite these advantages, Serb households have lower living standards, on average, than Albanian households. Most of the difference in living standards between Serb and Albanian households is due to unobserved non-economic factors. This result has serious implications for the political economy of policymaking in post-conflict Kosovo.

Since the early days of cinema the creation of artificial life with its various implications has been a popular topic on screen. Amongst the large number of films that deal with the theme of androids Bryan Forbes’ "The Stepford Wives" (1975) is noticeable for its focus on questions of gender and the relationship between the sexes. The film is set in a contemporary small suburban town where frustrated husbands have found a special way of dealing with their emancipated wives by replacing them with docile life-like robots. Mixing elements of the thriller and horror genres with farce and comedy "The Stepford Wives" was the first American mainstream film to deal explicitly with Women’s Lib. Unlike Ira Levin in his much more ambivalent novel that the film was based on, Forbes and his actors deliberately set out to make a feminist satire, and according to some critics succeeded in producing an important document of second wave feminism which soon acquired cult status. However, it also provoked a number of negative reactions from feminists who were very uncomfortable with a film in which men get away with murdering the female population of an entire town. A closer inspection reveals that the satirical element of the film is indeed not prominent and frequently counteracted, at times facilitating a misogynist rather than a feminist interpretation. This is mainly due to the ending of the film which implies the murderous elimination of the female protagonist. Unlike all other cinematic and literary works that feature androids "The Stepford Wives" shows the successful creation of artificial life which does not backfire. In addition, the film which clearly categorises itself as a thriller and horror movie, and specifically alludes to the tradition of threatened yet strong female characters in these genres, at the same time defies this convention in favour of a seemingly misogynist ending. Thus the way in which "The Stepford Wives" refuses to comply with the traditions of both the android theme and the horror genre, involuntarily serves to undermine its intention as a feminist social satire.

The reactivity of Amberlite (IRA-67) base "heterogeneous" resin in Sonogashira cross-coupling of 8-bromoguanosine 1 with phenylacetylene 3 to give 2 has been examined. Both 1 and 2 coordinate to Pd and Cu ions, which explains why at equivalent catalyst loadings, the homogeneous reaction employing triethylamine base is poor yielding. X-ray photo-electron spectroscopy (XPS) has been used to probe and quantify the active nitrogen base sites of the Amberlite resin, and postreaction Pd and Cu species. The Pd2Cl3(PPh)2 precatalyst and CuI cocatalyst degrade to give Amberlite-supported metal nanoparticles (average size ∼2.7 nm). The guanosine product 2 formed using the Amberlite Pd/Cu catalyst system is of higher purity than reactions using a homogeneous Pd precatalyst, a prerequisite for use in biological applications.

Objective: To analyze the recent epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in a UK tertiary referral center. Methods: We collected epidemiological and laboratory data on all cases of MRSA bacteremia from September 1, 2005 to December 31, 2007. Results: There were 195 clinically significant episodes. Most were hospital-acquired. Only one episode occurred in patients without a history of hospital admission in the previous 12 months. An intravascular device was the most common focus of infection (37%), with no identifiable source found in 35% of episodes. Twenty-eight percent of patients died within 30 days of bacteremia. Mortality was significantly higher in the absence of an identifiable focus. Failure to include an antibiotic active against MRSA in the empirical treatment was only significantly associated with death in patients showing signs of hemodynamic instability (p < 0.001). No isolates had a minimum inhibitory concentration to vancomycin above 1.5. mg/l and no heteroresistance to glycopeptide antibiotics (heteroresistant vancomycin-intermediate Staphylococcus aureus; hVISA) was detected. All isolates were sensitive to daptomycin, tigecycline, and linezolid. Conclusions: Despite improvement in infection control measures, medical devices remain the most common source of infection. Inappropriate empirical antibiotic usage is associated with a poor outcome in patients with signs of severe sepsis. Susceptibility to glycopeptides and newer antibiotics remains good. © 2010 International Society for Infectious Diseases.

The theoretical construct of control has been defined as necessary (Etzioni, 1965), ubiquitous (Vickers, 1967), and on-going (E. Langer, 1983). Empirical measures, however, have not adequately given meaning to this potent construct, especially within complex organizations such as schools. Four stages of theory-development and empirical testing of school building managerial control using principals and teachers working within the nation's fourth largest district are presented in this dissertation as follows: (1) a review and synthesis of social science theories of control across the literatures of organizational theory, political science, sociology, psychology, and philosophy; (2) a systematic analysis of school managerial activities performed at the building level within the context of curricular and instructional tasks; (3) the development of a survey questionnaire to measure school building managerial control; and (4) initial tests of construct validity including inter-item reliability statistics, principal components analyses, and multivariate tests of significance. The social science synthesis provided support of four managerial control processes: standards, information, assessment, and incentives. The systematic analysis of school managerial activities led to further categorization between structural frequency of behaviors and discretionary qualities of behaviors across each of the control processes and the curricular and instructional tasks. Teacher survey responses (N=486) reported a significant difference between these two dimensions of control, structural frequency and discretionary qualities, for standards, information, and assessments, but not for incentives. The descriptive model of school managerial control suggests that (1) teachers perceive structural and discretionary managerial behaviors under information and incentives more clearly than activities representing standards or assessments, (2) standards are primarily structural while assessments are primarily qualitative, (3) teacher satisfaction is most closely related to the equitable distribution of incentives, (4) each of the structural managerial behaviors has a qualitative effect on teachers, and that (5) certain qualities of managerial behaviors are perceived by teachers as distinctly discretionary, apart from school structure. The variables of teacher tenure and school effectiveness reported significant effects on school managerial control processes, while instructional levels (elementary, junior, and senior) and individual school differences were not found to be significant for the construct of school managerial control.

The study of diatoms in core HC11 collected from the southwestern part of Chukchi Sea, allowed to distinguish 3 diatoms ecological zones, reflecting paleoenvironmental changes during the last 2300 years. The sediment age was based on the sedimentation rates, determined by 210Pb and radiocarbon dating of mollusk shells. The environmental changes of Chukchi Sea revealed by examination of diatoms correlates with global climate changes - the warming of the early and middle Subatlantic and cooling of the late Subatlantic (Little Ice Age). Warming early and middle Subatlantic in the Chukchi Sea was probably stronger than the warming of the late 20th century and was not accompanied by significant changes in sea level.

The role of the hero is changing, slightly irregular, but it’s purpose is constant. The line that separates good from evil is frequently so thin that sometimes the main hero can act in a negative way, casting doubts about his own nature in the pursuit of good. This paper aims to inquire into the character’s heroic condition showing two variations of this archetype in the context of postmodern cinema: the “clear hero”, and the “dark hero”. The former keeps the most traditional values of the hero, while the latter provides a dimension which distinguishes it from the previous one: his experience executing evil as a part of his process to heroici­ty. Postmodernity implies an ambivalence in the character’s identity which can be comparable to the hero’s role, and to his way of making good. The “clear hero” does not imply negative features in the active nature of the hero, whilst the “dark hero” does include them. Through the protagonists of Gladiator (Scott, 2000) and Batman Begins (Nolan, 2005) are offered both heroic perspectives based on a selection of their principal ac­tions which have been subjected to analysis according to some parameters: behavior, implication, and cause. The decisive action will also be signalized, according to the narration’s teleonomy in reason of the favorable or unfavorable sense for the hero. Finally, each character will be observed from its archetype. By analyzing their actions from these perspectives, we observe the clear hero and the dark hero as affordable categories for the heroic role.

Skepticism regarding witchcraft, characteristic (but not exclusive) of the Spanish lands, corresponds with a particular view of evil’s etiology. Whereas paradigmatic texts of radical demonology, as the Malleus Maleficarum, gave a conclusive step towards the demonization of natural evil (as they put the blame on the devil and the witches for calamities and plagues), texts of Castilian origin, as Alonso de Espina’s Fortalitium fidei, embraced the traditional position: they considered the devil as a promoter of moral evil in the world, meanwhile natural evil is seen as a result of the wrath of God for the sins of His people –particularly, the sin of Christian princes. I argue that the distinction between these two ways of thinking the causality of the world’s misfortunes can be read in political terms.

Les antimoniures sont des semi-conducteurs III-V prometteurs pour le développement de dispositifs optoélectroniques puisqu'ils ont une grande mobilité d'électrons, une large gamme spectrale d'émission ou de détection et offrent la possibilité de former des hétérostructures confinées dont la recombinaison est de type I, II ou III. Bien qu'il existe plusieurs publications sur la fabrication de dispositifs utilisant un alliage d'In(x)Ga(1-x)As(y)Sb(1-y) qui émet ou détecte à une certaine longueur d'onde, les détails, à savoir comment sont déterminés les compositions et surtout les alignements de bande, sont rarement explicites. Très peu d'études fondamentales sur l'incorporation d'indium et d'arsenic sous forme de tétramères lors de l'épitaxie par jets moléculaires existent, et les méthodes afin de déterminer l'alignement des bandes des binaires qui composent ces alliages donnent des résultats variables. Un modèle a été construit et a permis de prédire l'alignement des bandes énergétiques des alliages d'In(x)Ga(1-x)As(y)Sb(1-y) avec celles du GaSb pour l'ensemble des compositions possibles. Ce modèle tient compte des effets thermiques, des contraintes élastiques et peut aussi inclure le confinement pour des puits quantiques. De cette manière, il est possible de prédire la transition de type de recombinaison en fonction de la composition. Il est aussi montré que l'indium ségrègue en surface lors de la croissance par épitaxie par jets moléculaires d'In(x)Ga(1-x)Sb sur GaSb, ce qui avait déjà été observé pour ce type de matériau. Il est possible d'éliminer le gradient de composition à cette interface en mouillant la surface d'indium avant la croissance de l'alliage. L'épaisseur d'indium en surface dépend de la température et peut être évaluée par un modèle simple simulant la ségrégation. Dans le cas d'un puits quantique, il y aura une seconde interface GaSb sur In(x)Ga(1-x)Sb où l'indium de surface ira s'incorporer. La croissance de quelques monocouches de GaSb à basse température immédiatement après la croissance de l'alliage permet d'incorporer rapidement ces atomes d'indium et de garder la seconde interface abrupte. Lorsque la composition d'indium ne change plus dans la couche, cette composition correspond au rapport de flux d'atomes d'indium sur celui des éléments III. L'arsenic, dont la source fournit principalement des tétramères, ne s'incorpore pas de la même manière. Les tétramères occupent deux sites en surface et doivent interagir par paire afin de créer des dimères d'arsenic. Ces derniers pourront alors être incorporés dans l'alliage. Un modèle de cinétique de surface a été élaboré afin de rendre compte de la diminution d'incorporation d'arsenic en augmentant le rapport V/III pour une composition nominale d'arsenic fixe dans l'In(x)Ga(1-x)As(y)Sb(1-y). Ce résultat s'explique par le fait que les réactions de deuxième ordre dans la décomposition des tétramères d'arsenic ralentissent considérablement la réaction d'incorporation et permettent à l'antimoine d'occuper majoritairement la surface. Cette observation montre qu'il est préférable d'utiliser une source de dimères d'arsenic, plutôt que de tétramères, afin de mieux contrôler la composition d'arsenic dans la couche. Des puits quantiques d'In(x)Ga(1-x)As(y)Sb(1-y) sur GaSb ont été fabriqués et caractérisés optiquement afin d'observer le passage de recombinaison de type I à type II. Cependant, celui-ci n'a pas pu être observé puisque les spectres étaient dominés par un niveau énergétique dans le GaSb dont la source n'a pu être identifiée. Un problème dans la source de gallium pourrait être à l'origine de ce défaut et la résolution de ce problème est essentielle à la continuité de ces travaux.

Introdução: A correção cirúrgica do aneurisma da aorta abdominal (AAA), por Endovascular Aneurysm Repair (EVAR) ou cirurgia convencional (CC), pode agravar a função renal a curto prazo. Esta complicação, mais frequente nos doentes com insuficiência renal crónica (IRC), associa-se a pior prognóstico a longo prazo. O objetivo deste trabalho foi quantificar o agravamento da função renal após reparação do AAA em doentes com IRC prévia e demonstrar o consequente aumento da morbimortalidade. Métodos: Estudo retrospetivo em doentes com IRC estádios Chronic Kidney Disease 3-4 (TFGe 15-59ml/min), submetidos a correção eletiva de AAA entre fevereiro/2011 e fevereiro/2015 numa instituição terciária. Variáveis estudadas: idade, sexo, tipo de intervenção (convencional/EVAR) e estádio CKD. Endpoints: variação da creatinina e taxa de filtração glomerular com a cirurgia, complicações renais pós-operatórias, necessidade de reintervenção cirúrgica e mortalidade. A análise estatística foi realizada em SPSS. Resultados: Foram incluídos 71doentes. Quinze doentes (21%) foram operados por CC e 56 (78%) por EVAR. À data da intervenção, os doentes encontravam-se nos seguintes estádios da DRC: CKD 3 --- 65 (91%) e CKD 4 --- 6 (9%). A variac¸ão da TFG com a cirurgia foi −1,08±18,01mg/dl. Verificou-se IRC agudizada pós-operatória em 22 (31%) doentes e necessidade de diálise em 5 (7%). A mortalidade global foi 8,5%. Os doentes operados por EVAR tinham DRC mais avançada pré-operatoriamente, mas apresentaram menor agravamento da função renal. Variação TFG: EVAR 1,14±16,26ml/min vs. CC 9,40±22,11ml/min (p=0,022); variação creatinina: EVAR 0,17±1,03mg/dl vs. CC 0,81±1,47mg/dl (p=0,02). A agudização da IRC pós-operatória foi superior no grupo CC (53,3 vs. 28,6%; p=0,072), assim como a necessidade de diálise (20 vs. 3,6%, p=0,06). Os 6 doentes que faleceram (EVAR: 3; CC: 3) apresentaram maior agravamento da função renal (variação da creatinina: 1,41±1,63mg/dl vs. 0,20±1,07mg/dl, p=0,001; variação da TFG: −19,0±16,55ml/min; 0,57±17,34ml/min, p=0,007) e necessidade de diálise (50 vs. 3,1%, p=0,003). Conclusão: Os resultados demonstraram uma tendência para uma menor probabilidade de IRA, menor necessidade de diálise pós-operatória e menor mortalidade nos doentes tratados por EVAR. Contudo, o impacto da administração de contraste a médio/longo prazo, decorrente dos programas de vigilância pós-EVAR, deve ser considerado. Julgamos ser possível considerar que a realização de EVAR para o tratamento de doentes com AAA e IRC é um procedimento pelo menos tão seguro como a CC.

Objetivou-se, neste estudo exploratório/descritivo, identificar conhecimentos e necessidades dos cuidadores da criança com Infecção Respiratória Aguda (IRA) através de uma amostra de 129 crianças atendidas no serviço de crescimento e desenvolvimento de uma unidade de saúde. Foram aplicados formulários junto aos cuidadores, em seu domicílio, nos meses de fevereiro e março de 2002. Os cuidadores eram do sexo feminino, a maioria jovem, com ensino fundamental incompleto e com renda de 1 a 2 salários. Em relação aos primeiros cuidados com a criança doente, 48,2% dos cuidadores procuram o médico, 36,6% medicam por conta própria e 13,2% utilizam fitoterápicos. Como medidas de prevenção contra pneumonia em crianças com IRA leve, os cuidadores utilizam medidas de senso comum e sabem reconhecer sinais de gravidade das doenças, por experiências anteriores, revelando uma lacuna do conhecimento dos principais sinais e sintomas de doenças graves do trato respiratório
