Humans and fire: changing relations in early agricultural and built environments in the Zagros, Iran, Iraq

Fire-centred studies have recently been highlighted as powerful avenues for investigation of energy flows and relations between humans, materials, environments and other species. The aim in this paper is to evaluate this potential first by reviewing the diverse theories and methods that can be applied to investigate the ecological and social significance of anthropogenic fire, and second by applying these to new and existing data sets in archaeology. This paper examines how fire-centred approaches can inform on one of the most significant step-changes in human lifeways and inter-relations with environment and other species – the transition from mobile hunting-gathering to more sedentary agriculture in a key heartland of change, the Zagros region of Iraq and Iran, c. 12,000–8,000 BP. In the review and case studies multiple links are investigated between human fire use and environment, ecology, energy use, technology, the built environment, health, social roles and relations, cultural practices and catastrophic events

Gapet mellan en ledares självuppfattning och medarbetarnas uppfattningar

Leadership is about synchronizing people into doing actions together to reach a common goal. To be able to do such thing you have to be a good leader. A mutual feature between good leaders is a good self awareness in order to be able to lead others. By letting others evaluate the features of a leader it can give a good self image of the leaders’ leadership. This is for seeing if there is a gap between the leaders own and the co-workers opinions about the leaders’ leadership. The purpose is to analyze if there could be a gap between a leader and its co-workers opinions about the leaders’ leadership and also to analyze why such a gap could exist.The method that has been used for analyzing the leadership is a 360 degree evaluation. The 360 degree evaluation is used in such way that the chosen leader, beyond its self assessment, is getting evaluated by its co-workers closest to him or her. This was implemented by questionnaires and interviews. The questionnaires are made after Adizes leadership roles and Hersey and Blanchards’ situational leadership.A leader often has different features, these does not accentuate because of the organizational structure and the position of the leaders in the organization emphasizes different features.

Development, capabilities and technology : an evaluative framework

In this paper we present a framework to be used for evaluation of Information and Communication Technology for Development (ICT4D) projects. The framework is based on Sen´s notion of development as freedom where human capabilities and functionings are seen as key aspects to development. Sen´s capability approach presents an alternative way of seeing and evaluating development (alternative to more traditional ways of measuring development). The approach is based on expanding freedoms, or eliminating unfreedoms, for people so that they can live a life that they have reason to value. Even though Sen is referenced a lot in ICT4D literature the analysis rarely goes further then stating that Sen presents an alternative to traditional ways of development. Reasons can be that the capability approach does not specifically mention technology, in addition to the lack of guidelines presented by Sen on how to use the framework. The aim of this paper is to operationalize the evaluation process and to include a clear role for technology in Sen´s capability framework. The framework is validated with a case on distance education from Bangladesh. 

Opting out of oppositionality : toward an informed and engaged "third wave" feminism

I begin by citing a definition of "third wave" from the glossary in Turbo Chicks: Talking Young Feminisms at length because it communicates several key issues that I develop in this project. The definition introduces a tension within "third wave" feminism of building and differentiating itself from second wave feminism, the newness of the term "third wave," its association with "young" women, complexity of contemporary feminisms, and attention to multiple identities and oppressions. Uncovering explanations of "third wave" feminism that go beyond, like this one, generational associations, is not an easy task. Authors consistently group new feminist voices together by age under the label "third wave" feminists without questioning the accuracy of the designation. Most explorations of "third wave" feminism overlook the complexities and distinctions that abound among "young" feminists ; not all young feminists espouse similar ideas, tactics, and actions; and for various reasons, not all young feminists identify with a "third wave" of feminism. Less than a year after I began to learn about feminism I discovered Barbara Findlen's Listen Up: Voices From the Next Feminist Generation. Although the collection nor its contributors declare association with "third wave" feminism, consequent reviews and citations in articles identify it, along with Rebecca Walker's To Be Real: Telling the Truth and Changing the Voice of Feminism, as a major text of "third wave" feminism. Re-reading Listen Up since beginning to research "third wave" feminism, I now understand its fundamental influence on my research questions as a starting point for assessing persistent exclusion in contemporary feminism, rather than as a revolutionary text (as it is claimed to be in many reviews). Findlen begins the introduction with the bold claim, "My feminism wasn't shaped by antiwar or civil rights activism ..." (xi). Framing the collection with a disavowal of the influence women of color's organizational efforts negates, for me, the project's proclaimed commitment to multivocality. Though several contributions examine persistent exclusion within contemporary feminist movement, the larger project seems to rely on these essays to reflect this commitment, suggesting that Listen Up does not go beyond the "add and stir" approach to "diversity." Interestingly, this statement does not appear in the new edition of Listen Up published in 2001. And the content has changed with this new edition, including several more Latina contributors and other "corrective" additions.

Como desenvolver e implementar um programa de segurança empresarial - o caso da fundação getulio vargas

A Segurança Empresarial é um programa preventivo que visa proteger os valores de uma empresa, para preservação das condições operacionais dentro da normalidade. As empresas estão sujeitas a ameaças relacionadas às suas atividades no mercado em que atuam. Muitas dessas ameaças são conhecidas e identificadas e, dentro do possível, é estabelecido um programa de proteção de seus interesses. Entretanto, as ameaças aos demais bens da empresa não são evidentes, nem perceptíveis tão facilmente. As medidas tomadas para prevenir a efetivação dessas ameaças, por meio de um Programa de Segurança Empresarial ou para minorar os problemas decorrentes da concretização dessas ameaças, até a volta às condições habituais de operação das empresas, por meio da execução de um Plano de Contingência, são vistas, não raramente, como despesas e poucas vezes como investimento com retomo. Nem geram resultados operacionais para a empresa. o objetivo final desta dissertação de mestrado foi estabelecer um Programa de Segurança Empresarial para a Fundação Getulio Vargas - FGV, recomendando a revisão das normas e procedimentos de segurança que comporão o Manual de Segurança e sugerir que a FGV o inclua no Plano Estratégico. Para alcançar o objetivo final. foram definidos: Conceitos Básicos de Segurança e Contingência; Critérios de Classificação de Dados; Gestão do Processo de Segurança e Contingência; Função Administração de Segurança. Alguns tipos de pesquisa foram aplicados. Quanto aos meios, caracterizou-se como estudo de caso; para a elaboração das recomendações de revisão das normas e procedimentos de segurança, foram aplicadas pesquisas bibliográfica, documental e de campo. Quanto ao fim, pesquisa aplicada, motivada pela necessidade de resolver problemas concretos, com finalidade prática. Foram efetuadas visitas e entrevistas nas instalações da sede da FGV e no prédio da Bolsa de Valores do Rio de Janeiro - BVRJ. Dada a complexidade e abrangência da Segurança Empresarial, o estudo foi limitado a tratar de segurança física. Foi observada a necessidade da FGV rever as Normas e Procedimentos de Segurança Empresarial, buscando melhorar o nível de segurança geral e adotar instrumentos modernos de prevenção de ocorrência de sinistros que ponham em risco os valores da FGV, a saber: pessoas, instalações físicas, equipamentos, informações, suprimentos e facilidades de comunicação. Está sendo recomendada a adoção da metodologia Sistemática Integrada de Segurança e Contingência - SISC, para minimizarão dos impactos de situações emergências.

Desafios para a formação de parcerias no serviço creche da secretaria da assistência social da PMSP

Analisa os vínculos estabelecidos entre a Secretaria de Assistência Social da PMSP e algumas Entidades Sociais para a prestação do serviço creche. Investigou-se o campo da Assistência Social e o da relação entre a esfera pública estatal e a esfera privada, sem fins lucrativos, na provisão de serviços públicos. A partir de revisão bibliográfica, de pesquisa documental e de estudo de casos, dando voz a todos que se relacionam no convênio, definiu-se parcerias como sendo relações substantivas que implicam corresponsabilidades, compartilhamento de valores e comprometimentos. Analisou-se duas creches diretas, duas conveniadas e duas indiretas, (e as respectivas Entidades Sociais), além da SAS Regional de IQ/G e SAS Central. Foram escolhidas as creches que obtiveram avaliação positiva quanto ao seu desempenho e alcance de resultados. Considerou-se que tanto os serviços prestados de forma direta quanto os conveniados podem ter qualidade e sucesso no alcance de seus objetivos, sendo necessário, em qualquer das modalidades, ter presente aspectos como: transparência nas ações, diálogos permanentes, clarificação de papéis e competências, responsabilização e compromissos com causas e com acordos. Justificam-se os serviços conveniados em razão das questões conjunturais hoje postas, e da responsabilização por parte de toda uma sociedade no enfrentamento da questão social. Justificam-se os serviços diretos pela necessidade vital da afirmação do papel do Estado na provisão de serviços públicos para garantia de serviços de forma continuada com vistas à universalização. Indicou-se, como desafio a necessidade de rever a forma como estão se dando os vínculos entre os agentes estudados, na direção do estabelecimento de parcerias, bem como o desafio da apropriação da condução da política pública pelos órgãos de assistência social, consolidando como esfera pública não-estatal a ação das Entidades Sociais.

A implementação de ações de integração na segurança pública: o caso das polícias civil e militar do Rio Grande do Norte

The research aimed to understand the challenges for the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP. This study aimed to explore the gap with regard to the deepening of the possible causes that may hinder the implementation of integrated working between the police in public security, through a specific analysis on the state of Rio Grande do Norte. Was based on a theoretical framework that includes policies: general concepts, the steps of a public policy, the implementation stage , public security : conceptual definitions, policies on security in Brazil, the structure of public security in Brazil and systems police, Military Police x Civil Police: Roles and conflicts , integrating public security: the challenges to be overcome, the Unified public Safety (SUSP) and the main difficulties in the integration of the police. Being classified as to the purposes as an exploratory research on how to approach ranks as qualitative. The research unit was the Center for Integrated Operations Public Safety (CIOSP) through three subjects who were the chief CIOSP, the representative of the military police acting with the CIOSP, and representative civil police also active with the CIOSP. These subjects were chosen because of the understanding that individuals occupying senior positions would have more ability to respond to questions that guide the research problem. Data were collected through a set of interviews, qualitative data analysis was performed based content analysis, based on the definition of categories of analysis, gated time cross. With the results, it was revealed that the main problems of integration between the state police are treatment protocols, lack of political will and lack of infrastructure. The relationship between the Military Police and Civil Police in Rio Grande do Norte has differing cultural aspect, but can be considered as good value, professionalism and integrated operations. The implementation of CIOSP-RN followed the characteristics of the top-down model, the main difficulties in implementing the proposals of the SUSP, lack of own resources, the lack of standardization in public safety and the lack of professional training of public safety. It was concluded that with respect to the challenges to the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP, the actions follow the characteristics of the top-down model, with no autonomy of administrators public to say in decisions, which restricts the view of the public safety of the state

Modelagem de arranjos institucionais para implementação da diretriz de sistema de gestão de segurança e saúde ocupacional da organização internacional do trabalho ILO/OSH 2001 no brasil

The commitment assumed by Brazil to ILO in order to pursue actions toward the ILO/OSH-2001 adoption in the country poses the issue of modeling the institutional arrangement the set roles and relationship between government, standards organizations, health and safety organizations, professionals and other institutions to deploy the ILO/OSH-2001. This Thesis develop institutional arrangement models based on the current model and also in the ISO 9000 scheme and others. It is studied the US case with OSHA and VPP, the OHSAS 18001 and ANSI/AIHA Z-10, in addition to actual context of the regulating norms NR s. The scenarios developed are put to evaluation on feasibility, potential changes and effects on current MTE auditors work scheme. The main results are five scenarios developed and that the MTE auditors tend to be reactive to the change toward the ILO/OSH-2001.

"Eu pensei que ia sair daqui falando inglês": um estudo sistêmico-funcional sobre papéis sociais atribuídos por alunos de um curso de Letras/Inglês

Research in the area of teacher training in English as a Foreign Language (CELANI, 2003, 2004, 2010; PAIVA, 2000, 2003, 2005; VIEIRA-ABRAHÃO, 2010) articulates the complexity of beginning teachers classroom contexts aligned with teaching language as a social and professional practice of the teacher in training. To better understand this relationship, the present study is based on a corpus of transcribed interviews and questionnaires applied to 28 undergraduate students majoring in Letters/English emphasis, at a public university located in the interior of the Western Amazon region, soliciting their opinions about the reforms made in the curriculum of this Major. Interviews and questionnaires were used as data collection instruments to trace a profile of the students organized in Group 1, with freshmen and sophomore undergraduates who are following the 2009 curriculum, and Group 2, with junior and senior undergraduates who are following the 2006 curriculum. The objectives are to identify, to characterize and to analyze the types of pronouns, roles and social actors represented in the opinions of these students in relation to their teacher training curriculum. The theoretical support focuses on the challenge of historical and contemporary routes from English teachers initial education programs (MAGALHÃES; LIBERALLI, 2009; PAVAN; SILVA, 2010; ALVAREZ, 2010; VIANA, 2011; PAVAN, 2012). Our theoretical perspective is based on the Systemic Functional Grammar of Halliday (1994), Halliday and Hasan (1989), Halliday and Matthiessen (2004), Eggins (1994; 2004) and Thompson (2004). We focus on the concept of the Interpersonal meaning, specifically regarding the roles articulated in the studies by Delu (1991), Thompson and Thetela (1995), and in the Portuguese language such as Ramos (1997), Silva (2006) and Cabral (2009). Moreover, we ascribe van Leeuwen s (1997; 2003) theory of Representation of Social Actors as a theoretical framework in order to identify the sociological aspect of social actors represented in the students discourse. Within this scenario, the analysis unfolds on three levels: grammatical (pronouns), semantic (roles), and discursive (social actors). For the analysis of interpersonal realizations present in the students opinions, we use the computational program WordSmith Tools (SCOTT, 2010) and its applications Wordlist and Concord to quantify the occurrences of the pronouns I, You and They, which characterize the roles and social actors of the corpus. The results show that the students assigned the following roles to themselves: (i) apprentice to express their initial process of English language learning; (ii) freshman to reveal their choice of Major in Letters/English emphasis; (iii) future teacher to relate their expectations towards a practicing professional. To assign the roles to professors in the major, the students used the metaphor of modality (I think) to indicate the relationship of teacher training, while they are in the role of a student and as a future teacher. From these evidences the representation of the students as social actors emerges in roles such as: (i) active roles; (ii) passive roles and (iii) personalized roles. The social actors represented in the opinions of the students reflect the inclusion of these roles assigned to the actions expressed about their experiences and expectations derived from their teacher training classroom

Structural basis for metal ion coordination and the catalytic mechanism of sphingomyelinases D

Sphingomyelinases D (SMases D) from Loxosceles spider venom are the principal toxins responsible for the manifestation of dermonecrosis, intravascular hemolysis, and acute renal failure, which can result in death. These enzymes catalyze the hydrolysis of sphingomyelin, resulting in the formation of ceramide 1-phosphate and choline or the hydrolysis of lysophosphatidyl choline, generating the lipid mediator lysophosphatidic acid. This report represents the first crystal structure of a member of the sphingomyelinase D family from Loxosceles laeta (SMase I), which has been determined at 1.75-angstrom resolution using the quick cryo-soaking technique and phases obtained from a single iodine derivative and data collected from a conventional rotating anode x-ray source. SMase I folds as an (alpha/beta)(8) barrel, the interfacial and catalytic sites encompass hydrophobic loops and a negatively charged surface. Substrate binding and/or the transition state are stabilized by a Mg2+ ion, which is coordinated by Glu(32), Asp(34), Asp(91), and solvent molecules. In the proposed acid base catalytic mechanism, His(12) and His(47) play key roles and are supported by a network of hydrogen bonds between Asp(34), Asp(52), Trp(230), Asp(233), and Asn(252).

Developing a research agenda for promoting physical activity in Brazil through environmental and policy change

Objective. To identify the highest priorities for research on environmental and policy changes for promoting physical activity (PA) in Brazil; to uncover any gaps between researchers' and practitioners' priorities; and to consider which tools, methods, collaborative strategies, and actions could be useful to moving a research agenda forward.Methods. This was a mixed-methods study (qualitative and quantitative) conducted by Project GUIA (Guide for Useful Interventions for Activity in Brazil and Latin America) in February 2010-January 2011. A total of 240 individuals in the PA field (186 practitioners and 54 researchers) were asked to generate research ideas; 82 participants provided 266 original statements from which 52 topics emerged. Participants rated topics by "importance" and "feasibility;" a separate convenience sample of 21 individuals categorized them. Cluster analysis and multidimensional scaling were used to create concept maps and pattern matches.Results. Five distinct clusters emerged from the concept mapping, of which " effectiveness and innovation in PA interventions" was rated most important by both practitioners and researchers. Pattern matching showed a divergence between the groups, especially regarding feasibility, where there was no consensus.Conclusions. The study results provided the basis for a research agenda to advance the understanding of environmental and policy influences on PA promotion in Brazil and Latin America. These results should stimulate future research and, ultimately, contribute to the evidence-base of successful PA strategies in Latin America.

Effect of non-steroidal anti-inflammatory drugs (NSAID) on the histamine release induced by compound 48/80 and cardiac anaphylaxis in guinea-pig isolated heart

Histamine release from guinea pig heart treated with compound 48/80 was potentiated by the cyclooxygenase inhibitors indomethacin and piroxicam but not by aspirin or phenylbutazone. This differential effect suggests that the potentiation is not merely due to an inhibition of prostaglandin synthesis. Piroxicam potentiated the histamine release induced by cardiac anaphylaxis whereas indomethacin reduced this effect. The SRS-A antagonist FPL 55712 inhibited histamine release induced by cardiac anaphylaxis, but not that evoked by compound 48/80, and also prevented the potentiation due to indomethacin and piroxicam. In total, these data suggest that the potentiation of histamine release by piroxicam and indomethacin is probably due to a diversion of arachidonic acid metabolism from the cyclooxygenase to the lipoxygenase pathways. The resulting lipoxygenase products may then regulate histamine release, with the secretion due to antigen being more sensitive to such modulation than that evoked by compound 48/80.
