A dissertação preocupou-se em analisar as relações de bandidos e ex-bandidos com o pentecostalismo na Assembleia de Deus Fortificada em Cristo (ADFEC), situada na favela Jardim São Jorge, periferia da Cidade Ademar, região Sul da capital de São Paulo. Interessou-nos compreender as interações desses agentes e de qual maneira a igreja desempenhou seu trabalho em um espaço pentecostal. A pesquisa, teve como objetivo fundamental, examinar as aproximações da criminalidade e o pentecostalismo indicando suas rupturas e características peculiares. O trabalho de campo se dedicou em coletar dados que comprovassem atuação da ADFEC juntos aos agentes do crime, e em que medida a filiação religiosa dos agentes ganhava importância. Por fim, buscamos refletir sobre a adesão de bandidos e ex-bandidos ao pentecostalismo e a influência dessa adesão no cotidiano da comunidade.

Este estudo buscou investigar duas relações de interesse: a relação entre poder e cobertura de analistas financeiros no mercado acionário brasileiro, e a relação entre poder e assimetria informacional neste mercado, nos períodos de 2000 a 2010. O objetivo desta pesquisa envolveu verificar se o poder empresarial aumenta a assimetria informacional decorrentes dos custos de agência envolvidos e possibilidade de expropriação de valor (Jensen & Meckling, 1976), ou diminui a assimetria, uma vez que administração da empresa não se sente vulnerável a demissões ou possíveis embaraços a sua atuação, e opta por não omitir informações aos stakeholders (Bertrand & Mullainathan, 2003). Ainda relacionado ao ambiente informacional impactado pelo poder empresarial, buscou-se verificar se os analistas financeiros acompanham empresas que apresentam uma maior assimetria informacional, e assim cumprindo sua função de monitoramento da gestão empresarial (Healy & Palepu, 2001), ou menor assimetria, em decorrência dos custos envolvidos em se obter informações privadas (Frankel, Kothari & Weber, 2006). Com o uso de proxies criadas pela análise fatorial para capturar as especificidades relacionadas a poder empresarial e assimetria informacional no ambiente empresarial brasileiro, foram observadas uma relação negativa entre cobertura de analistas financeiros e poder empresarial e uma relação positiva entre assimetria e poder empresarial. Pelas hipóteses esquematizadas por Jiraporn, Liu e Kim (2012), que abarcam todas as relações possíveis entre assimetria, poder empresarial e cobertura de analistas financeiros, os resultados se enquadram na Hipótese da Opacidade.

Dating aggression is common among emerging adults, and women who experience aggression from a dating partner are at risk for elevated depression and posttraumatic stress (Dutton et al., 2006). Although some women end their relationships as a result of aggression, other women remain committed to their partner, and aggression tends to escalate over time. The current study explored the role that depression and posttraumatic stress play in ending aggressive dating relationships as well as changes in these symptoms after ending such a relationship. The current study also sought to identify factors predictive of individual differences in emerging adults' commitment to their aggressive dating relationships. A sample of 148 emerging adult women currently in an aggressive dating relationship completed questionnaires about themselves and their relationship; measures of rejection sensitivity, self-worth, and romantic relational style were included as predictors of the Investment Model variables (e.g., investment, satisfaction, quality of alternatives, and commitment; Rusbult, 1980). Two assessments were completed six months apart. Neither depression nor posttraumatic stress predicted ending an aggressive relationship. However, ending an aggressive relationship was associated with experiencing less physical aggression, which mediated reductions in posttraumatic stress. A more avoidant romantic style indirectly predicted commitment through relationship satisfaction and investment. Both commitment and rejection sensitivity significantly predicted continuing an aggressive relationship six months later.

The body of research on the relationship functioning of adults with attention deficit hyperactivity disorder (ADHD) is relatively small; the aim of the present study is to advance our understanding of this topic. It has been estimated that three to ten percent of children and one to five percent of adults have impairing symptoms of ADHD, which is a total of 4 million children and 4-5 million adults in the U.S. (Wender, 2000). A recent prevalence study found that approximately 4.4% of adults in the U.S. meet the criteria for a diagnosis of ADHD (Kessler et al., 2006). Children with ADHD show innate temperamental characteristics, usually inattentiveness, distractibility, impulsivity, restlessness, demandingness, hyperreactivity, low tolerance for frustration, temperoutbursts, bossiness and stubbornness, and mood lability, along with an innate proclivity for academic underachievement. It has been estimated that one- to two-thirds of children with ADHD have symptoms that continue into adulthood, and for 40-50% of these adults, these symptoms are serious enough to cause impairment in functioning (Everett & Everett, 1999; Wender, 2000). Research suggests that the majority of cases are transmitted genetically, but some may be due to exposure to environmental toxins such as lead. Consumption of excess sugar or allergies to food may exacerbate or mimic ADHD symptoms in some children, but they are not a cause of ADHD (Wender, 2000). One hypothesized cause of the symptoms associated with ADHD is a deficit in the brain's executive functioning (Barkley & Gordon, 2002). Executive functioning can be conceptualized as the ability to inhibit, organize, and plan behaviors. Barkley and Gordon (2002) define it as the abilityto self-direct and regulate behaviors toward future goals, including social behaviors and goals. Other research suggests that executive functioning consists of inhibition, control of interference, verbal and nonverbal working memory, emotional regulation, attention, verbal fluency, visual scanning, and processing speed. Studies have shown impairments in these areas among adults with ADHD (Barkley & Gordon, 2002; Barkley, Murphy & Kwasnik, 1996; Goldstein, 2002).

The purpose of the present study was to examine the relationship of harmonious and obsessive passion to perceptions of task and social cohesion in team sport athletes. Participants were 370 competitive (N=252) and recreational (N=118) athletes ranging from 18- to 28-years-old (Mage=20.20, SD=1.52) from a wide variety of team sports. Participants completed the Passion Scale (Vallerand et al., 2003) and the Group Environment Questionnaire (Carron et al., 1985). A MANOVA revealed that competitive athletes were more passionate and had higher perceptions of cohesion than did recreational athletes. Multiple regression analyses revealed a positive relationship between both harmonious and obsessive passion and both task (ATG-T, GI-T) and social (ATG-S, GI-S) cohesion. Theoretical and practical implications are discussed pertaining to the importance of harmonious and obsessive passion in athletes and perceptions of cohesion in competitive and recreational sport.

We investigate the mechanics of slope failures on the Nankai accretionary complex offshore Japan in the vicinity of a major out-of-sequence thrust fault (termed the "megasplay"). Incorporating laboratory-measured shear strength of slope sediments sampled during Integrated Ocean Drilling Project (IODP) Expeditions 315 and 316 with local seafloor slope angles from bathymetric data and constraints on in-situ effective stress conditions from drilling, we find that slopes in the study area are stable and submarine landslides are not expected to occur under static conditions. In order to assess the possibility of slope failure triggered by coseismic rupture of the megasplay fault, we use empirical relations for strong ground motion attenuation from earthquakes with Mw 6-9. We find that the slope sediments should be stable based on computations from one model, developed from a catalog of worldwide subduction zone earthquakes (Youngs et al., 1997, doi:10.1785/gssrl.68.1.58). However, using a different model developed primarily from a catalog of crustal earthquakes in Japan (Kanno et al., 2006, doi:10.1785/0120050138), we find that slopes should be unstable for earthquakes 8 <= Mw <= 9, and possibly unstable for events with 6 <= Mw < 8, depending on the proximity of rupture to the seafloor. Considering limitations of the models and geologic observations of slope failure recurrence, the true slope stability is likely to be in between the predictions of the two models, and we suggest that it may be modulated by long-term pore pressure fluctuations.

The Palaeocene/Eocene thermal maximum represents a period of rapid, extreme global warming approx ~55 million years ago, superimposed on an already warm world (Zachos et al., 2003, doi:10.1126/science.1090110; Bowen et al., 2004, doi:10.1038/nature03115; Thomas et al., 2002, doi:10.1130/0091-7613(2002)030<1067:WTFFTF>2.0.CO;2). This warming is associated with a severe shoaling of the ocean calcite compensation depth **4 and a >2.5 per mil negative carbon isotope excursion in marine and soil carbonates (Zachos et al., 2003, doi:10.1126/science.1090110; Bowen et al., 2004, doi:10.1038/nature03115; Thomas et al., 2002, doi:10.1130/0091-7613(2002)030<1067:WTFFTF>2.0.CO;2; Zachos et al., doi:10.1126/science.1109004). Together these observations indicate a massive release of 13C-depleted carbon (Zachos et al., doi:10.1126/science.1109004) and greenhouse-gas-induced warming. Recently, sediments were recovered from the central Arctic Ocean (Backman et al., 2006, doi:10.2204/iodp.proc.302.2006), providing the first opportunity to evaluate the environmental response at the North Pole at this time. Here we present stable hydrogen and carbon isotope measurements of terrestrial-plant- and aquatic-derived n-alkanes that record changes in hydrology, including surface water salinity and precipitation, and the global carbon cycle. Hydrogen isotope records are interpreted as documenting decreased rainout during moisture transport from lower latitudes and increased moisture delivery to the Arctic at the onset of the Palaeocene/Eocene thermal maximum, consistent with predictions of poleward storm track migrations during global warming (Backman et al., 2006, doi:10.2204/iodp.proc.302.2006). The terrestrial-plant carbon isotope excursion (about ~4.5 to ~6 per mil) is substantially larger than those of marine carbonates. Previously, this offset was explained by the physiological response of plants to increases in surface humidity (Bowen et al., 2004, doi:10.1038/nature03115). But this mechanism is not an effective explanation in this wet Arctic setting, leading us to hypothesize that the true magnitude of the excursion - and associated carbon input - was greater than originally surmised. Greater carbon release and strong hydrological cycle feedbacks may help explain the maintenance of this unprecedented warmth.of this unprecedented warmth.

Recent coccoliths from 74 surface sediment samples recovered from the southeastern Pacific off Chile were examined quantitatively to investigate modern regional gradients of sea surface productivity and temperature. All findings are based on coccolith accumulation rates. Therefore an approach was designed to estimate recent sedimentation rates based on 210Pb and bulk chemistry analyses of the same set of surface samples. Highest total coccolith accumulation rates were found off north-central Chile, where seasonal upwelling takes place. Based on amultiple linear regression between calculated coccolith accumulation rates andWorld Ocean Atlas derived sea surface temperatures, a calibrationmodel to reconstruct annual average temperatures of the uppermost 75 mof thewater column is provided. Themodelwas cross-validated and the SST estimateswere compared with SST observed and SST estimates based on diatoms and planktonic foraminifera, showing a good correlation.

Ice cores provide a record of changes in dust flux to Antarctica, which is thought to reflect changes in atmospheric circulation and environmental conditions in dust source areas (Forster et al., 2007; Diekmann et al. 2000, doi:10.1016/S0031-0182(00)00138-3; Winckler et al., 2008, doi:10.1126/science.1150595; Reader et al., 1999, doi:10.1029/1999JD900033; Mahowald et al., 1999, doi:10.1029/1999JD900084; Petit et al., 1999, doi:10.1038/20859; 1990, doi:10.1038/343056a0 Delmonte et al., 2009, doi:10.1029/2008GL033382; Lambert et al., 2008, doi:10.1038/nature06763). Isotopic tracers suggest that South America is the dominant source of the dust (Grousset et al., 1992, doi:10.1016/0012-821X(92)90177-W; Basile et al., 1997, doi:10.1016/S0012-821X(96)00255-5; Gaiero et al., 2007, doi:10.1016/j.chemgeo.2006.11.003), but it is unclear what led to the variable deposition of dust at concentrations 20-50 times higher than present in glacial-aged ice (Petit et al., 1990, doi:10.1038/343056a0; Lambert et al., 2008, doi:10.1038/nature06763). Here we characterize the age and composition of Patagonian glacial outwash sediments, to assess the relationship between the Antarctic dust record from Dome C (refs Lambert et al., 2008, doi:10.1038/nature06763; Wolff et al., 2006, doi:10.1038/nature04614) and Patagonian glacial fluctuations (Sugden et al., 2005; McCulloch et al., 2005, doi:10.1111/j.0435-3676.2005.00260.x; Kaplan et al., 2008, doi:10.1016/j.quascirev.2007.09.013) for the past 80,000 years. We show that dust peaks in Antarctica coincide with periods in Patagonia when rivers of glacial meltwater deposited sediment directly onto easily mobilized outwash plains. No dust peaks were noted when the glaciers instead terminated directly into pro-glacial lakes. We thus propose that the variable sediment supply resulting from Patagonian glacial fluctuations may have acted as an on/off switch for Antarctic dust deposition. At the last glacial termination, Patagonian glaciers quickly retreated into lakes, which may help explain why the deglacial decline in Antarctic dust concentrations preceded the main phase of warming, sea-level rise and reduction in Southern Hemisphere sea-ice extent (Wolff et al., 2006, doi:10.1038/nature04614).

As field determinations take much effort, it would be useful to be able to predict easily the coefficients describing the functional response of free-living predators, the function relating food intake rate to the abundance of food organisms in the environment. As a means easily to parameterise an individual-based model of shorebird Charadriiformes populations, we attempted this for shorebirds eating macro-invertebrates. Intake rate is measured as the ash-free dry mass (AFDM) per second of active foraging; i.e. excluding time spent on digestive pauses and other activities, such as preening. The present and previous studies show that the general shape of the functional response in shorebirds eating approximately the same size of prey across the full range of prey density is a decelerating rise to a plateau, thus approximating the Holling type 11 ('disc equation') formulation. But field studies confirmed that the asymptote was not set by handling time, as assumed by the disc equation, because only about half the foraging time was spent in successfully or unsuccessfully attacking and handling prey, the rest being devoted to searching. A review of 30 functional responses showed that intake rate in free-living shorebirds varied independently of prey density over a wide range, with the asymptote being reached at very low prey densities (< 150/m(-2)). Accordingly, most of the many studies of shorebird intake rate have probably been conducted at or near the asymptote of the functional response, suggesting that equations that predict intake rate should also predict the asymptote. A multivariate analysis of 468 'spot' estimates of intake rates from 26 shorebirds identified ten variables, representing prey and shorebird characteristics, that accounted for 81 % of the variance in logarithm-transformed intake rate. But four-variables accounted for almost as much (77.3 %), these being bird size, prey size, whether the bird was an oystercatcher Haematopus ostralegus eating mussels Mytilus edulis, or breeding. The four variable equation under-predicted, on average, the observed 30 estimates of the asymptote by 11.6%, but this discrepancy was reduced to 0.2% when two suspect estimates from one early study in the 1960s were removed. The equation therefore predicted the observed asymptote very successfully in 93 % of cases. We conclude that the asymptote can be reliably predicted from just four easily measured variables. Indeed, if the birds are not breeding and are not oystercatchers eating mussels, reliable predictions can be obtained using just two variables, bird and prey sizes. A multivariate analysis of 23 estimates of the half-asymptote constant suggested they were smaller when prey were small but greater when the birds were large, especially in oystercatchers. The resulting equation could be used to predict the half-asymptote constant, but its predictive power has yet to be tested. As well as predicting the asymptote of the functional response, the equations will enable research workers engaged in many areas of shorebird ecology and behaviour to estimate intake rate without the need for conventional time-consuming field studies, including species for which it has not yet proved possible to measure intake rate in the field.

The last decade or so has witnessed the emergence of the national innovation system (NIS) phenomenon. Since then, many scholars have investigated NIS and its implementation in different countries. However, there are very few investigations into the relationship between the NIS of a country and its national innovation capacity. This paper aims to make a contribution in this area by examining the link that currently exists between these two topics. Whilst examining this relationship, we also explore internationalisation and technology transfer, being cognate areas that have been investigated during the same period. This follows our assertion that the link between NIS and national innovation capacity is the mechanism of internationalisation and technology transfer. The NIS approach was introduced in the late 1980s (see Freeman, 1987; Dosi et al., 1988) and further elaborated later (see Lundvall, 1992; Nelson, 1993; Edquist, 1997). In essence, a country?s NIS is a historically grown subsystem of the entire national economy consisting of organisations and institutions which play a major role in the innovative activity in the country. In the NIS approach, interactions within organisations as well as the interplay between organisations and institutions are of central importance. The NIS approach has been used to reveal the structure of the innovation processes and the main actors involved in them in industrialised and emerging countries. Although the national focus remains strong, it has been accompanied by studies seeking to analyse the notion of systems of innovation at an international level and at a sub-national scale (Archibugi et al., 1999). Dosi in the edition of Archibugi et al. (1999) argues that the general background of the discussion of national systems is the observation of non-random distributions across countries of: corporate capabilities; organisational forms; strategies; and ultimately revealed performances, in terms of production efficiency and inputs productivities, rates of innovation, rates of adoption/diffusion of innovation themselves, dynamics of market shares on the world markets, growth of income and employment. They also mention that there are several approaches to NIS. Nelson (1993) focuses upon the specificities of national institutions and policies supporting directly or indirectly innovation, diffusion and skills accumulation. Patel and Pavitt (1991) have stressed the links between the national patterns of technological accumulation and the competencies and innovative strategies of a few major national companies. Amable et al (1997) and Soskice (1993) and Zysman (1994) focus on the specifics of national institutions including, for example, the forms of organization, financial and labour markets, training institutions, forms of state intervention in the economy etc. However, the most common reference is by Lundvall (1992) who argues that the focus on the national level is associated with the fact that national economies vary according to their production system and their institutional framework and these differences are in turn strengthened by different historical experiences, language and culture. On the other hand, the national innovation capability consists of abilities to create and carry new technological possibilities through to economic practice. The term covers a wide range of activities from capability to invent to capability to innovate and to capability to improve existing technology beyond the original design parameters (Kim, 1997). The term innovation is often associated by many with technological change at international frontiers. However, technological capability is not the same as innovation capability. Technological capability refers to assimilation, use, adaptation, and change to existing technologies. It also enables the creation of new technologies and development of new products and processes in response to changing economic environments. It denotes operational command over knowledge (Kim, 1997). It is manifested not merely by the knowledge possessed, but, more important, by the uses to which that knowledge can be put and by the proficiency with which it is applied in the activities of investment and production and in the creation of new knowledge (Westphal et al., 1985). Therefore, the analytical framework that is used in this paper is based on the way a country derives from its NIS a national innovation capacity. There are two perspectives that are identified on this way. These are internationalisation and technology transfer. Even though NIS is not directly related to national innovation capacity, to achieve national innovation capacity from NIS, the country should have the ability for technology transfer. Technology transfer is a link between these two phenomena. On the other hand, internationalisation can be either the input or the output of the relationship between NIS and national innovation capability. If a company is investing in a country because of its national innovation capacity, this can be regarded as an input to the relationship between NIS and national innovation capacity. If this company is investigating the national innovation capacity of a country then, for its internationalisation, the national innovation capacity should be important, which in turn means this company is active in innovation and innovation is also an important success factor. The interrelationship between the investment of the company and the NIS of the country (assuming that the country is competent and competitive in technology transfer) will generate and improve that country?s national innovation capacity. This is the output of internationalisation from the relationship between NIS and national innovation capacity. When companies are evaluating whether to internationalise, they investigate certain factors in the countries in which they are considering to invest. The ability to transfer technology is dependent on ability to adopt a new technology and also on the learning derived from this technology. If countries wish to attract innovation related investment they need to show their ability to have a NIS and also the capability to transfer technology. Without the technology transfer capability, the NIS is not functioning. Therefore, companies that internationalise will investigate the factors common to NIS, technology transfer, and their business needs. Through this paper we will demonstrate this link though its mechanisms. Our research will be through extensive literature review and identifying relevant aspects of previous research carried out by the authors. It will investigate certain factors of different countries that are successful in attracting innovation related foreign direct investment. Through these, we will point out the factors that are important for the link and mechanisms of NIS and national innovation capability.

Previous studies into student volunteering have shown how formally organized volunteering activities have social, economic and practical benefits for student volunteers and the recipients of their volunteerism (Egerton, 2002; Vernon & Foster, 2002); moreover student volunteering provides the means by which undergraduates are able to acquire and hone transferable skills sought by employers following graduation (Eldridge & Wilson, 2003; Norris et al, 2006). Within the UK Higher Education Sector, a popular mechanism for accessing volunteering is through formally organized student mentoring programmes whereby more ‘senior’ students volunteer to mentor less experienced undergraduates through a particular phase of their academic careers, including the transition from school or college to university. The value of student mentoring as a pedagogical tool within Higher Education is reflected in the literature (see for example, Bargh & Schul, 1980, Hartman,1990, Woodd, 1997). However, from a volunteering perspective, one of the key issues relates to the generally accepted conceptualisation of volunteering as a formally organized activity, that is un-coerced and for which there is no payment (Davis Smith, 1992, 1998; Sheard, 1995). Although the majority of student mentoring programs discussed in the paper are unpaid and voluntary in nature, in a small number of institutions some of the mentoring programs offered to students provide a minimum wage for mentors. From an ethical perspective, such payments may cause difficulties when considering potential mentors’ motivations and reasons for participating in the program. Additionally, institutions usually only have one or two paid mentoring programs running alongside several voluntary programmes – sometimes resulting in an over-subscription for places as paid mentors to the detriment of unpaid programs. Furthermore, from an institutional perspective, student mentoring presents a set of particular ethical problems reflecting issues around ‘matching’ mentors and mentees in terms of gender, race, ethnicity and religion. This is found to be the case in some ‘targeted’ mentoring programs whereby a particular demographic group of students are offered access to mentoring in an attempt to improve their chances of academic success. This paper provides a comparative analysis of the experiences and perceptions of mentors and mentees participating in a wide-range of different mentoring programs. It also analyzes the institutional challenges and benefits associated with managing large scale student volunteering programs. In doing so the paper adds to third sector literature by critiquing the distinctive issues surrounding student volunteering and by discussing, in-depth, the management of large groups of student volunteers. From a public policy perspective, the economic, educational, vocational and social outcomes of student volunteering make this an important subject meriting investigation. Little is known about the mentoring experiences of student volunteers with regards to the ‘added value’ of participating in campus-based volunteering activities. Furthermore, in light of the current economic downturn, by drawing attention to the contribution that student volunteering plays in equipping undergraduates with transferable ‘employability’ related skills and competencies (Andrews & Higson, 2008), this paper makes an important contribution to current educational and political debates. In addition to providing the opportunity for students to acquire key transferable skills, the findings suggest that mentoring encourages students to volunteer in other areas of university and community life. The paper concludes by arguing that student mentoring provides a valuable learning experience for student volunteer mentors and for the student and pupil mentees with whom they are placed.
