O presente trabalho trata de uma investigação sobre a presença e o processo do luto por morte nas escolas e, também, como professores, coordenadores e diretores podem apoiar estudantes enlutados. Um significativo índice de mortes de estudantes demonstra que o processo experimentado por estudantes enlutados é realidade presente nas escolas. Por sua relevância, entende-se ser fundamental que o tema seja considerado na educação escolar. A opção metodológica para o desenvolvimento do estudo pautou-se pela realização de uma revisão da literatura para teoricamente traçar uma perspectiva histórica e social fundamentada principalmente em Paiva (2011), Kovács (2003), Franco (2002), Kübler-Ross (1996). Optou-se, também, por usar noticiários e documentários. Para a realização da pesquisa empírica, a investigação teve como campo 2 escolas públicas da Grande São Paulo e 23 sujeitos entre os quais professores, coordenador e diretores. Desse universo, 13 sujeitos eram da escola A e 10 da escola B; todos atuando diretamente com os alunos. Realizouse, em uma primeira etapa, a aplicação de um questionário estruturado, respondido inicialmente pelos 23 sujeitos. Na segunda etapa da pesquisa, utilizou-se como método a entrevista de aprofundamento com uma amostra de 10 profissionais (dois diretores, uma coordenadora e sete professores). Após responderem ao questionário, esses profissionais desejaram participar espontaneamente dessa segunda etapa, para que se pudesse obter maior aprofundamento das questões relacionadas à investigação. Por meio da análise de conteúdo dos relatos obtidos, foram construídos três temas: significado em perder uma pessoa por morte; facilidades e/ou dificuldades em lidar com as questões de luto/morte na escola; papel de gestores e educadores frente às manifestações de luto entre estudantes na escola. Como referências para análises dos dados, elencaram-se Queiroz (2003) e Demartini (2001). A pesquisa permitiu averiguar a presença e o processo de luto por morte nas escolas e como professores, coordenadores e diretores abordam o tema da morte, do luto e da perda. A pesquisa procurou também conhecer e refletir sobre os significados que os educadores têm acerca do luto e morte no contexto escolar. Esse conhecimento possibilitou conhecer como alguns professores e outros profissionais da educação trabalham (ou não) com o processo do luto na escola. As análises construídas a partir dos temas revelaram que alguns profissionais que vivenciam ou vivenciaram a dor pela perda por morte têm dificuldades em lidar com o tema na escola por não saberem lidar com essa situação. Outra questão considerada é a falta de apoio da escola e a falta de preparo dos profissionais ao lidar com o luto na escola. Os relatos apresentam a morte interdita de jovens como uma realidade presente nas escolas e ocupando cada vez mais espaço. Esse assunto desafiador não se encerra. Há muitas ações que a escola necessita realizar. Este trabalho propõe caminhos para novas investigações e desafios.

This article discusses the policy and politics of dual nationality in Germany. It contrasts the policy reality, in which dual nationality is tolerated in a wide range of cases, with Germany's continued opposition in principle to this phenomenon. It then analyzes political, cultural and electoral factors to explain why this opposition persists despite these widespread exceptions. In conclusion, the article argues that by continuing formally to oppose dual nationalities, Germany in effect discourages naturalizations and thereby continues to operate a broadly exclusive citizenship.

The aim of this research was to investigate the molecular interactions occurring in the formulation of non-ionic surfactant based vesicles composed monopalmitoyl glycerol (MPG), cholesterol (Chol) and dicetyl phosphate (DCP). In the formulation of these vesicles, the thermodynamic attributes and surfactant interactions based on molecular dynamics, Langmuir monolayer studies, differential scanning calorimetry (DSC), hot stage microscopy and thermogravimetric analysis (TGA) were investigated. Initially the melting points of the components individually, and combined at a 5:4:1 MPG:Chol:DCP weight ratio, were investigated; the results show that lower (90 C) than previously reported (120-140 C) temperatures could be adopted to produce molten surfactants for the production of niosomes. This was advantageous for surfactant stability; whilst TGA studies show that the individual components were stable to above 200 C, the 5:4:1 MPG:Chol:DCP mixture show ∼2% surfactant degradation at 140 C, compared to 0.01% was measured at 90 C. Niosomes formed at this lower temperature offered comparable characteristics to vesicles prepared using higher temperatures commonly reported in literature. In the formation of niosome vesicles, cholesterol also played a key role. Langmuir monolayer studies demonstrated that intercalation of cholesterol in the monolayer did not occur in the MPG:Chol:DCP (5:4:1 weight ratio) mixture. This suggests cholesterol may support bilayer assembly, with molecular simulation studies also demonstrating that vesicles cannot be built without the addition of cholesterol, with higher concentrations of cholesterol (5:4:1 vs 5:2:1, MPG:Chol:DCP) decreasing the time required for niosome assembly. © 2013 Elsevier B.V.

Information and communication technology (ICT) developments have strongly affected supply chain management (SCM) in recent years. ICT has had a great impact on all supply chain processes including planning, purchasing, production management, stock management, physical distribution and related integration management. Technology has become an important dimension of third party logistics (3PL) service supply as competitive advantage increasingly depends on the ability to create value for customers through the effective application of ICT. Within this process, while large 3PLs are gaining substantial benefits from technology usage and implementation, the magnitude of changes spurred by ICT dissemination in small logistics service providers remains unclear. This is reflected by the existing gap in literature where the role and competitive developing processes of small 3PLs are seriously underestimated. This gives rise to the need to develop research and investigation in this particular area. The objective of this paper is to narrow the knowledge gap in the field of ICT adoption in small 3PLs through an empirical investigation. It presents the results of a survey on a sample of small Italian 3PLs.

Purpose: The purpose of the research described in this paper is to disentangle the rhetoric from the reality in relation to supply chain management (SCM) adoption in practice. There is significant evidence of a divergence between theory and practice in the field of SCM. Design/methodology/approach: Based on a review of extant theory, the authors posit a new definitional construct for SCM – the Four Fundamentals – and investigated four research questions (RQs) that emerged from the theoretical review. The empirical work comprised three main phases: focussed interviews, focus groups and a questionnaire survey. Each phase used the authors’ definitional construct as its basis. While the context of the paper’s empirical work is Ireland, the insights and results are generalisable to other geographical contexts. Findings: The data collected during the various stages of the empirical research supported the essence of the definitional construct and allowed it to be further developed and refined. In addition, the findings suggest that, while levels of SCM understanding are generally quite high, there is room for improvement in relation to how this understanding is translated into practice. Research limitations/implications: Expansion of the research design to incorporate case studies, grounded theory and action research has the potential to generate new SCM theory that builds on the Four Fundamentals construct, thus facilitating a deeper and richer understanding of SCM phenomena. The use of longitudinal studies would enable a barometer of progress to be developed over time. Practical implications: The authors’ definitional construct supports improvement in the cohesion of SCM practices, thereby promoting the effective implementation of supply chain strategies. A number of critical success factors and/or barriers to implementation of SCM theory in practice are identified, as are a number of practical measures that could be implemented at policy/supply chain/firm level to improve the level of effective SCM adoption. Originality/value: The authors’ robust definitional construct supports a more cohesive approach to the development of a unified theory of SCM. In addition to a profile of SCM understanding and adoption by firms in Ireland, the related critical success factors and/or inhibitors to success, as well as possible interventions, are identified.

Background: Electrosurgery units are widely employed in modern surgery. Advances in technology have enhanced the safety of these devices, nevertheless, accidental burns are still regularly reported. This study focuses on possible causes of sacral burns as complication of the use of electrosurgery. Burns are caused by local densifications of the current, but the actual pathway of current within patient's body is unknown. Numerical electromagnetic analysis can help in understanding the issue. Methods: To this aim, an accurate heterogeneous model of human body (including seventy-seven different tissues), electrosurgery electrodes, operating table and mattress was build to resemble a typical surgery condition. The patient lays supine on the mattress with the active electrode placed onto the thorax and the return electrode on his back. Common operating frequencies of electrosurgery units were considered. Finite Difference Time Domain electromagnetic analysis was carried out to compute the spatial distribution of current density within the patient's body. A differential analysis by changing the electrical properties of the operating table from a conductor to an insulator was also performed. Results: Results revealed that distributed capacitive coupling between patient body and the conductive operating table offers an alternative path to the electrosurgery current. The patient's anatomy, the positioning and the different electromagnetic properties of tissues promote a densification of the current at the head and sacral region. In particular, high values of current density were located behind the sacral bone and beneath the skin. This did not occur in the case of non-conductive operating table. Conclusion: Results of the simulation highlight the role played from capacitive couplings between the return electrode and the conductive operating table. The concentration of current density may result in an undesired rise in temperature, originating burns in body region far from the electrodes. This outcome is concordant with the type of surgery-related sacral burns reported in literature. Such burns cannot be immediately detected after surgery, but appear later and can be confused with bedsores. In addition, the dosimetric analysis suggests that reducing the capacity coupling between the return electrode and the operating table can decrease or avoid this problem. © 2013 Bifulco et al.; licensee BioMed Central Ltd.

Much has been written about the potential impact of Lean Agile paradigm on firm's supply chain performance. However, most of the existing studies mainly pointed out Lean is for cost reduction, whereas Agility is for attaining flexibility. There are little empirical studies in literature that examined how Lean Agile paradigm impacts on supply chain performance. This paper aims to address this gap by studying the influence of Lean and Agility paradigms on a single commodity supply chain delivery performance in the aerospace industry. Data was collected from four separate 'Rigid pipes' supply chains to study how manufacturing alignment impacts on the delivery performance. Implications of the study to practitioners and academia are discussed and future research outlined.

A fenntarthatóság kérdését a vállalati működésben számos kutatás elemzi. A vizsgálatokat azonban érdemes kiterjeszteni a vállalatokat beszállítóikkal összekötő kapcsolatrendszerre és az annak menedzseléséért felelős beszerzésre is, hiszen a nagy vállalatok beszerzési döntései jelentős értékükön keresztül fontos motiváló erőt jelentenek a beszállító vállalatok egy sokkal szélesebb hálózata számára. Tanulmányunk célja áttekinteni a fenntarthatóság három pillérjének beszerzési értelmezésének lehetőségeit, ehhez kapcsolódva bemutatni azokat a motivációs tényezőket, amelyek biztosíthatják azt, hogy a beszerzés a gyakorlatban is kezelni tudja a fenntarthatóság szempontjait. A bemutatott eredmények az irodalom feltérképezésén alapszanak, és egy olyan kutatás részét képezik, melynek során vállalati beszerzési szakembereket kérdezünk a fenntartható beszerzéssel kapcsolatos vállalati gyakorlatról és tapasztalataikról. A kutatás a Budapesti Corvinus Egyetemen folyó „Versenyben a világgal” kutatási program keretében készült. = Sustainability issues in literature are getting more and more attention. In this study the focus is extended to purchasing and supplier relationships as companies influence their supply base by the priorities of their sourcing decision. This paper addresses sustainability in purchasing in a comprehensive way including green, social responsibility and corporate growth issues. The results of a research project which aims to reveal and structure the meaning of sustainable purchasing and the motivating forces leading companies to make efforts in purchasing for sustainability and means applied to attain achievements at some fields of sustainability. After presenting the results of literature review, some theory development was done to create a framework in which it is possible to describe the sustainability means applied and the motivating force behind. This framework serves as a basis of an empirical investigation among Hungarian companies. The empirical results validated the theoretical framework: the number and the characteristics of sustainability activities were determined by the type of motivation (to avoid negative effects, compliance to expectations, to attain positive effects). Our research project was part of the research project “In Global Competition”.

A környezeti hatások rendszerint túlmutatnak egy vállalat határain, éppen ezért az ellátási lánc kontextusban a környezeti szempontok érvényesítése során fontos szerep jut a beszerzési döntéseknek is. Számos olyan példát lehetne említeni, amikor egy adott szempont szerint egy alternatíva környezetileg előnyös, de az ellátási lánc egészét nézve már környezetterhelő. A környezeti hatások ellátási lánc szinten való mérése azonban komoly kihívásokat jelent. Ezzel jelentős kutatásokat és fejlesztéseket inspirált a téma. Az egyik olyan terület, amelyben komoly kutatási eredmények születtek, az a környezeti szempontok beszállítói értékelésbe való beépítése. A kutatások ezen irányához csatlakozva a szerzők tanulmányunkban azt keresik, hogyan lehet meghatározni az egyik legáltalánosabban használt szállítóértékelési módszerben, a súlyozott pontrendszerben egy adott szemponthoz azt a súlyt, amely mellett az adott szempont már döntésbefolyásoló tényezővé válik. Ehhez a DEA (Data Envelopment Analysis) összetett indikátorok (Composite Indicators, CI) módszerét alkalmazzák. A szempontok közös súlyának fontossága megállapításához a lineáris programozás elméletét használják. _____ Management decisions often have an environmental effect not just within the company, but outside as well, this is why supply chain context is highlighted in literature. Measuring environmental issues of supply decisions raise a lot of problems from methodological and practical point of view. This inspires a rapidly growing literature as a lot of studies were published focusing on how to incorporate environmental issues into supplier evaluation. This paper contributes to this stream of research as it develops a method to help weight selection. In the authors’ paper the method of Data Envelope Analysis (DEA) is used to study the extension of traditional supplier selection methods with environmental factors. The selection of the weight system can control the result of the selection process.

Recently, wireless network technology has grown at such a pace that scientific research has become a practical reality in a very short time span. Mobile wireless communications have witnessed the adoption of several generations, each of them complementing and improving the former. One mobile system that features high data rates and open network architecture is 4G. Currently, the research community and industry, in the field of wireless networks, are working on possible choices for solutions in the 4G system. 4G is a collection of technologies and standards that will allow a range of ubiquitous computing and wireless communication architectures. The researcher considers one of the most important characteristics of future 4G mobile systems the ability to guarantee reliable communications from 100 Mbps, in high mobility links, to as high as 1 Gbps for low mobility users, in addition to high efficiency in the spectrum usage. On mobile wireless communications networks, one important factor is the coverage of large geographical areas. In 4G systems, a hybrid satellite/terrestrial network is crucial to providing users with coverage wherever needed. Subscribers thus require a reliable satellite link to access their services when they are in remote locations, where a terrestrial infrastructure is unavailable. Thus, they must rely upon satellite coverage. Good modulation and access technique are also required in order to transmit high data rates over satellite links to mobile users. This technique must adapt to the characteristics of the satellite channel and also be efficient in the use of allocated bandwidth. Satellite links are fading channels, when used by mobile users. Some measures designed to approach these fading environments make use of: (1) spatial diversity (two receive antenna configuration); (2) time diversity (channel interleaver/spreading techniques); and (3) upper layer FEC. The author proposes the use of OFDM (Orthogonal Frequency Multiple Access) for the satellite link by increasing the time diversity. This technique will allow for an increase of the data rate, as primarily required by multimedia applications, and will also optimally use the available bandwidth. In addition, this dissertation approaches the use of Cooperative Satellite Communications for hybrid satellite/terrestrial networks. By using this technique, the satellite coverage can be extended to areas where there is no direct link to the satellite. For this purpose, a good channel model is necessary.

This dissertation analyzes the theory and practice of the Cuban postmodern writer Severo Sarduy (1937–1993) from his early adult years in Cuba to his exile period in Paris, France, where he lived until his death. By studying his narrative through the light of his theoretical essays, this paper demonstrates that the author created his own type of reading model—from and for Sarduy. His literary work is influenced by three major elements: (post)structuralism, psychoanalysis, and Buddhism, which combined form what Sarduy himself called the Neobarroque style. The Sarduyan writing is a transgressive exercise expressed through his concept of simulación. This style breaks with the traditional art concept of mimesis (the representation of reality in the western world), and therefore with the correspondence between the signifier and the signified. Sarduy does not intend to represent reality but to go beyond it, achieving by his technique of signifying exhaustion to represent absence itself. The Neobarroque of Severo Sarduy is an aesthetic of the empty signifier based on the reckless expenditure, and ultimately exhaustion, of the artifices of language that precipitates in a signifier chain towards the infinite. His language does not transmit a message but it signifies itself, that is, a means without an end. Paradoxically, this signifier chain produces an excess of metaphors beyond the material limits of language and its support, the page. The space beyond language is the hipertelic technique inherited by Sarduy from his literary master, José Lezama Lima. This is also the empty space of no signification or nonsense in which occurs the depersonalization of the speaking subject; in Buddhist terminology this becomes the dissolution of the ego. The Sarduyan language is determined by a Lacanian psychoanalytic erotic drive (pulsion) known as the Barroquean desire, a death drive which directly relates to the exile condition of the author. But the genesis of this desire lies in a primordial desire of encounter with his origin: mother, maternal language, paradise, God. That is the reason why Sarduy not only poses an aesthetic question but also an ontological one. This other dimension of the Sarduyan writing is based on a liberating drive that permeates all his work—an ontological liberation expressed through language. The empty space created in the text provides the subject with the possibility of fusion with the all. Ultimately, Sarduy strives for a language that goes beyond the symbolic limits towards a place of constant dissolution, evanesce, and death-horror vacui. This corroborates the Sarduyan statement: “la simulación enuncia el vacío y la muerte.”

Faced with the violence, criminality and insecurity now threatening peace and democratic governance in Central America, the region’s governments have decided to use the Armed Forces to carry out actions in response to criminal actions, looking to improve their performance. Although public demand for including the Armed Forces in these functions takes place within a legally legitimate framework, it is motivated by tangible circumstances such as increased levels of violence, delinquency and crime. Despite being coupled with the perception of institutional weakness within the security and judicial system (particularly police) and the recognition of prestige, efficiency, discipline and severity in fulfilling the Armed Forces’ missions, these arguments are insufficient to legitimize the use of the military as a police force. Within this context, this paper reflects on the implications or consequences of the use of the Armed Forces in duties traditionally assigned to the police in the Central American region with the goal of contributing to the debate on this topic taking place in the Americas. To achieve this end, first we will focus on understanding the actual context in which a decision is made to involve the Armed Forces in security duties in the region. Second, we will examine the effects and implications of this decision on the Armed Forces’ relations within their respective societies. Third and finally, considering this is already a reality in the region, this paper will provide recommendations. The main findings of this research, resulting from the application of an analyticaldescriptive and historically based study, are organized in three dimensions: the political dimension, by implication referring to the relationship between the ultimate political authority and the Armed Forces; the social dimension, by implication the opinion of citizens; and other implications not only affecting the structural and cultural organization of armies and police but also the complementary operational framework within a context of comprehensive response by the State. As a main conclusion, it poses there is an environment conducive to the use of the Armed Forces in citizen’s security, in view of the impact of threats provoked by criminal structures of a military nature currently operating in Central America. However, this participation creates an inevitable social and political impact if implemented in isolation or given a political leading role and/or operational autonomy. This participation poses risks to the institutions of the Armed Forces and the police as well. Finally, this paper identifies an urgent need for the Armed Forces’ role to be more clearly defined with regard to security matters, limiting it to threats that impact States’ governability and existence. Nonetheless, Central American States should seek a COMPREHENSIVE response to current crime and violence, using all necessary institutions to confront these challenges, but with defined roles and responsibilities for each and dynamic coordination to complement their actions.

The arrival of Cuba’s Information Technology (IT) and Communications Minister Ramiro Valdés to Venezuela in the Spring of 2010 to serve as a ‘consultant’ to the Venezuelan government awakened a new reality in that country. Rampant with deep economic troubles, escalating crime, a murder rate that has doubled since Chávez took over in 1999, and an opposition movement led by university students and other activists who use the Internet as their primary weapon, Venezuela has resorted to Cuba for help. In a country where in large part traditional media outlets have been censored or are government-controlled, the Internet and its online social networks have become the place to obtain, as well as disseminate, unfiltered information. As such, Internet growth and use of its social networks has skyrocketed in Venezuela, making it one of Latin America’s highest Web users. Because of its increased use to spark political debate among Venezuelans and publish information that differs with the official government line, Chávez has embarked on an initiative to bring the Internet to the poor and others who would otherwise not have access, by establishing government-sponsored Internet Info Centers throughout the country, to disseminate information to his followers. With the help of Cuban advisors, who for years have been a part of Venezuela’s defense, education, and health care initiatives, Chávez has apparently taken to adapting Cuba’s methodology for the control of information. He has begun to take special steps toward also controlling the type of information flowing through the country’s online social networks, considering the implementation of a government-controlled single Internet access point in Venezuela. Simultaneously, in adapting to Venezuela’s Internet reality, Chávez has engaged online by creating his own Twitter account in an attempt to influence public opinion, primarily of those who browse the Web. With a rapidly growing following that may soon reach one million subscribers, Chávez claims to have set up his own online trench to wage cyber space battle.

In addition, this dissertation approaches the use of Cooperative Satellite Communications for hybrid satellite/terrestrial networks. By using this technique, the satellite coverage can be extended to areas where there is no direct link to the satellite. The issue of Cooperative Satellite Communications is solved through a new algorithm that forwards the received data from the fixed node to the mobile node. This algorithm is very efficient because it does not allow unnecessary transmissions and is based on signal to noise ratio (SNR) measures.
