A Lateglacial archaeological site in the far north-west of Europe at Rubha Port an t-Seilich, Isle of Islay, western Scotland: Ahrensburgian-style artefacts, absolute dating and geoarchaeology

The exact pattern, process and timing of the human re-colonization of northern Europe after the end of the last Ice Age remain controversial. Recent research has provided increasingly early dates for at least pioneer explorations of latitudes above 54°N in many regions, yet the far north-west of the European landmass, Scotland, has remained an unexplained exception to this pattern. Although the recently described Hamburgian artefacts from Howburn and an assemblage belonging to the arch-backed point complex from Kilmelfort Cave have established at least a sporadic human presence during earlier stages of the Lateglacial Interstadial, we currently lack evidence for Younger Dryas/Greenland Stadial 1 (GS-1) activity other than rare stray finds that have been claimed to be of Ahrensburgian affiliation but are difficult to interpret in isolation. We here report the discovery of chipped stone artefacts with technological and typological characteristics similar to those of the continental Ahrensburgian at a locality in western Scotland. A preliminary analysis of associated tephra, pollen and phytoliths, along with microstratigraphic analysis, suggest the artefacts represent one or more episodes of human activity that fall within the second half of GS-1 and the Preboreal period

Rethinking the Conversion of Scotland in the fifth and sixth centuries

Reconsidering the initial Christian Conversion of Scotland in the fifth and sixth centuries AD, using archaeological and historical evidence, it is argued that this was carried out by missionaries from what had been Roman Britain. It is shown that this missionary activity - and similar British missions in Ireland - represents the first instance of Western missionary work beyond the former Roman imperial frontiers. The location of the northern frontier of Roman Britain in the fourth century, and the meaning of Pictish Class 1 symbol stones, are discussed as part of the broader argument.

The impact of the abrupt 8.2 ka cold event on the Mesolithic population of western Scotland: a Bayesian chronological analysis using ‘activity events’ as a population proxy

The potential impact of the abrupt 8.2 ka cold event on human demography, settlement patterns and culture in Europe and the Near East has emerged as a key theme in current discussion and debate. We test whether this event had an impact on the Mesolithic population of western Scotland, a case study located within the North Atlantic region where the environmental impact of the 8.2 ka event is likely to have been the most severe. By undertaking a Bayesian analysis of the radiocarbon record and using the number of activity events as a proxy for the size of the human population, we find evidence for a dramatic reduction in the Mesolithic population synchronous with the 8.2 ka event. We interpret this as reflecting the demographic collapse of a low density population that lacked the capability to adapt to the rapid onset of new environmental conditions. This impact of the 8.2 ka event in the North Atlantic region lends credence to the possibility of a similar impact on populations in Continental Europe and the Near East.

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.

Multiscale Analysis of Topographic Surface Roughness in the Midland Valley, Scotland

Surface roughness is an important geomorphological variable which has been used in the Earth and planetary sciences to infer material properties, current/past processes, and the time elapsed since formation. No single definition exists; however, within the context of geomorphometry, we use surface roughness as an expression of the variability of a topographic surface at a given scale, where the scale of analysis is determined by the size of the landforms or geomorphic features of interest. Six techniques for the calculation of surface roughness were selected for an assessment of the parameter`s behavior at different spatial scales and data-set resolutions. Area ratio operated independently of scale, providing consistent results across spatial resolutions. Vector dispersion produced results with increasing roughness and homogenization of terrain at coarser resolutions and larger window sizes. Standard deviation of residual topography highlighted local features and did not detect regional relief. Standard deviation of elevation correctly identified breaks of slope and was good at detecting regional relief. Standard deviation of slope (SD(slope)) also correctly identified smooth sloping areas and breaks of slope, providing the best results for geomorphological analysis. Standard deviation of profile curvature identified the breaks of slope, although not as strongly as SD(slope), and it is sensitive to noise and spurious data. In general, SD(slope) offered good performance at a variety of scales, while the simplicity of calculation is perhaps its single greatest benefit.

Kartläggning av tillslagsprecision i fotboll

Syfte Syftet med studien är att analysera tillslagsprecision i fotboll och jämföra eventuella skillnader mellan juniorer och seniorer på både herr- och damsidan. Metod Totalt 30 elitspelare varav 16 herrar och 14 damer utförde tester i tillslagsprecision. De färdigheter som testades var passning och skott. Upplägget var 60 skott (30 stillaliggande och 30 halvvolley) och 80 passningar (20 stillaliggande bästa fot, 20 rullande bästa fot, 20 stillaliggande näst bästa fot och 20 rullande näst bästa fot). Testresultaten analyserades via Excel och Kinovea, där kunde medelvärden och standardavvikelser för varje testperson och testgrupp räknas ut. Resultat Resultatet visar att det endast var signifkant skillnad på ett av sex moment vad gäller tillslagsprecisionen på herrsidan. På damsidan var det ingen signifikant skillnad på något moment. Slutsatser Författarna har i denna studie identifierat en platå mellan spelare i åldrarna 16-18 år och seniorspelare vad gäller tillslagsprecision. Spelare i åldrarna 16-18 är lika bra som seniorspelare på de individuella färdigheterna passning och skott. Denna platå kan vara resultatet av för lite individuell träning, sk isolerad träning vad det gäller tillslagsprecision, på föreningsträningarna. Om föreningstränarna följer den utbildning SvFF ger dem ska endast två minuter per träning gå till varje individuell färdighet (13 st enligt SvFF). Bristen av tid för dessa färdigheter kan vara en avgörande faktor för att utvecklingen av tillslagsprecision står stilla idag.

Beyond indifferent players: on the existence of prisoners dilemmas in games with amicable and adversarial preferences

Why don’t agents cooperate when they both stand to gain? This question ranks among the most fundamental in the social sciences. Explanations abound. Among the most compelling are various configurations of the prisoner’s dilemma (PD), or public goods problem. Payoffs in PD’s are specified in one of two ways: as primitive cardinal payoffs or as ordinal final utility. However, as final utility is objectively unobservable, only the primitive payoff games are ever observed. This paper explores mappings from primitive payoff to utility payoff games and demonstrates that though an observable game is a PD there are broad classes of utility functions for which there exists no associated utility PD. In particular we show that even small amounts of either altruism or enmity may disrupt the mapping from primitive payoff to utility PD. We then examine some implications of these results.

A new playing field: retrospective voting and soccer in Brazil

O propósito deste estudo é analisar o possível impacto que um viés emocional possa ter nos julgamentos dos eleitores. Nesse sentido utilizamos o futebol como fonte exógena de um choque. O nosso modelo de efeitos fixos nos leva a concluir que vitórias de equipes no final de semana da eleição estão associadas a maior votação no incumbente indicando que um viés emocional pode influenciar o eleitor.

Processos de adaptação e vivências profissionais interculturais no futebol globalizado: profissionais brasileiros da bola

O presente trabalho tem como tema central as vivências interculturais dos atores do mundo do futebol que, a cada dia mais, perpassam diversas culturas como caminho ascensional das suas carreiras. O objeto dos Estudos Organizacionais Interculturais dá ênfase às interações entre pessoas de diferentes culturas, e esta é a problemática proposta nesta discussão, que enseja debates, convida à discussões interdisciplinares e evoca uma temática que instiga novos olhares sobres questões transculturais. Embora a literatura do campo aborde em sua maioria a adaptação e vivência de executivos expatriados, o presente trabalho pretende investigar a vivência e adaptação de jogadores e técnicos de futebol que trabalham em diferentes contextos. O referencial teórico é formado por áreas do conhecimento, promovendo uma conversa interdisciplinar, particularmente oriundas da Administração e Sociologia, bem como a literatura sobre futebol, que é o objeto empírico da tese. Metodologicamente a pesquisa adota uma abordagem qualitativa e interpretativista. A coleta de dados foi feita através de entrevistas com profissionais reconhecidos, que exerceram ou ainda estão exercendo suas atividades no exterior. Notadamente, e de forma prática, identificam-se questões de adaptação cultural que podem interferir no sucesso profissional da pessoa que se desloca para territórios estrangeiros, podendo influenciar na sua vida pessoal, dificultando o seu sucesso, por variados fatores, tais como: o idioma em si, a dificuldade de compreensão das figuras de linguagem e expressões inerentes a cada idioma, a mecânica laboral de cada cultura, o contraste no estilo de vida, os códigos culturais, linguagem corporal, hábitos cotidianos, estranhamento ao universo do outro, hábitos alimentares. Pretende-se que este estudo possa contribuir para ampliar e incitar o arcabouço teórico dos estudos de administração intercultural, através das vivências e proposições para uma melhor adaptação e vivência de jogadores e técnicos de futebol no exterior.

A dinâmica do campo organizacional e a adoção de estratégias na carcinicultura do RN

This study aimed to understand the relations inside the organizational Structuring of the shrimp Field - the shrimp agribusiness placed in Rio Grande do Norte State and the strategies adopted by its players. In order to achieve that, semi-structured interviews were conducted with samples of various organizations that act in the field, like cooperatives, associations, enterprises of different links in the chain, universities and state agencies. The interviews built up a large collection of secondary data. As expected, it was found that Field and strategies are related in a recursive way: the configuration of the field, a result from his own biography, has decisively influenced the strategies adopted by its actors, who, as evolved, eventually caused further changes in the Field and outlines the plot of this area of interaction. It was found, for example, that after thirty-five years of its genesis, the Field of shrimp RN still has a low level of institutionalization, which helps to understand the difficulty of its actors in establish strategies based on partnerships and cooperation; Those actions are so necessary to alleviate the effects of the crisis that devastated the industry since 2004. It was noticed, however, that this level of institutionalization is a result, beside other factors, the very strategies that field actors are embracing along its trajectory. Thus, this study hopes to have contributed both to the necessary revival of the agency to institutional phenomenon, cited by Oliver (1991), and to meet the need for more contextualized approaches to organizational strategies (MINTZBERG, 1987; CLEGG, 2004; WHITTINGTON, 2004; 2006; SARAIVA and CARRIERI, 2007). It is an exploratory study that needs further investigation in order to get deep in this research. In this sense, others methodologies and theoretical perspectives need to be used, especially those relating to the seizure of the disputes and discursive aspects of power, as salient in the field investigated. Moreover, in terms of "practical actions", it is suggested that, as soon as possible, the main actors of the field (cooperatives, companies, and state entities in class) can be able of agglutinate efforts to support the shrimp field in RN State and make sustainable actions, which can promote the development of activity in a global view. On the apse of shrimp activities everybody wanted to be the "father of the child," Now, someone has to "stay in the goal."

Relações trabalhistas e estilo de vida do atleta profissional de futebol do Rio Grande do Norte

Brazilian Law n° 9.615 of 24 March, 1998 established new paradigms in the employment relations existent between the soccer athlete and the sport association, both of whom are accustomed to the former legislation. They do not seem to have organized themselves in the sense of understanding the practical effects of the legal precepts currently in force, raising doubts that hinder the professional practice of the former and the performance of the latter in relation to managing these human resources. The purpose of this study is to analyze the degree of knowledge displayed by the professional soccer athlete about the legal recourses at his disposal in relation to the employment relations established in his work contract, as well as investigating the stress habits and stress situations that he most often experiences. This descriptive study consisted of a sample of 105 players under contract with clubs participating in the final phase of the state soccer championship. A questionnaire was used as the data collection instrument, whose analysis allows us to verify the lack of knowledge, on the part of the subjects studied, about the laws that regulate their profession, as well as identifying the stress habits and stress situations that are most reflected in their lifestyle. The lack of knowedge of regulate norms of their profession influences, in a negative way, in the lifestyle of soccer professional athlete from Rio Grande do Norte, Brasil
