The rapidity of ocean acidification intensifies selection pressure for resilient phenotypes, particularly during sensitive early life stages. The scope for selection is greater in species with greater within-species variation in responses to changing environments, thus enhancing the potential for adaptation. We investigated among-male variation in sperm swimming responses (percent motility and swimming speeds) of the serpulid polychaete Galeolaria caespitosa to near- (delta pH 0.3) and far-future ocean acidification (delta pH 0.5). Responses of sperm swimming to acidification varied significantly among males and were overall negative. Robust sperm swimming behavior under near-future ocean acidification in some males may ameliorate climate change impacts, if traits associated with robustness are heritable, and thereby enhance the potential for adaptation to far-future conditions. Reduced sperm swimming in the majority of male G. caespitosa may decrease their fertilization success in a high CO2 future ocean. Resultant changes in offspring production could affect recruitment success and population fitness downstream.

Background: Climate change will lead to intense selection on many organisms, particularly during susceptible early life stages. To date, most studies on the likely biotic effects of climate change have focused on the mean responses of pooled groups of animals. Consequently, the extent to which inter-individual variation mediates different selection responses has not been tested. Investigating this variation is important, since some individuals may be preadapted to future climate scenarios. Methodology/Principal Findings: We examined the effect of CO2-induced pH changes ("ocean acidification") in sperm swimming behaviour on the fertilization success of the Australasian sea urchin Heliocidaris erythrogramma, focusing on the responses of separate individuals and pairs. Acidification significantly decreased the proportion of motile sperm but had no effect on sperm swimming speed. Subsequent fertilization experiments showed strong inter-individual variation in responses to ocean acidification, ranging from a 44% decrease to a 14% increase in fertilization success. This was partly explained by the significant relationship between decreases in percent sperm motility and fertilization success at delta pH = 0.3, but not at delta pH = 0.5. Conclusions and Significance: The effects of ocean acidification on reproductive success varied markedly between individuals. Our results suggest that some individuals will exhibit enhanced fertilization success in acidified oceans, supporting the concept of 'winners' and 'losers' of climate change at an individual level. If these differences are heritable it is likely that ocean acidification will lead to selection against susceptible phenotypes as well as to rapid fixation of alleles that allow reproduction under more acidic conditions. This selection may ameliorate the biotic effects of climate change if taxa have sufficient extant genetic variation upon which selection can act.

Design influences behaviour, whether it's planned or not. Service Design has a great opportunity to lead the emerging field of design for behavioural change, helping guide and shape experiences to benefit users, service providers and wider society. In this article, presented as an evolving conversation between research and practice, Nick Marsh (EMC Consulting) and Dan Lockton (Brunel University) discuss and explore design patterns for influencing behaviour through Service Design, and how Service Designers and academics can work together for social benefit.

Communicating science can be challenging at any educational level. We used informal and experiential learning to engage groups of potential University applicants in one project that involved staging a play in one of the teaching laboratories at the University of Worcester whilst a second project designed a play in house and took this to schools. In the first project the plot centred on stem cell research. School pupils and students from FE Colleges were offered complementary sessions including a lecture exploring the science behind stem cell research, a discussion on ethical aspects involved and a practical using university facilities. We ascertained attitudes to Higher Education in the students participating before and after the event. We found an enhanced view of the science and a highly significant change in attitude to attending University for students taking vocational subjects at FE level. The second project was aimed at exploring attitudes to ethics and animal welfare among a cohort of 15 – 18 year olds. Students engaged with the issues in the drama to a high degree. Our conclusions are that drama is an excellent way to inform potential students about higher education and HE level science in particular. Additionally we demonstrated the importance of events taking place at HE institutions in order to maximise change in attitudes to HE.

This thesis covers the challenges of creating and maintaining an introductory engineering laboratory. The history of the University of Illinois Electrical and Computer Engineering department’s introductory course, ECE 110, is recounted. The current state of the course, as of Fall 2008, is discussed along with current challenges arising from the use of a hand-wired prototyping board with logic gates. A plan for overcoming these issues using a new microcontroller-based board with a pseudo hardware description language is discussed. The new microcontroller based system implementation is extensively detailed along with its new accompanying description language. This new system was tried in several sections of the Fall 2008 semester alongside the old system; the students’ final performances with the two different approaches are compared in terms of design, performance, complexity, and enjoyment. The system in its first run shows great promise, increasing the students’ enjoyment, and improving the performance of their designs.

This study examines the simultaneous effect of individual (selfefficacy) and group variables (cohesion and gender diversity) on satisfaction. A laboratory study was conducted involving 373 college students randomly distributed across 79 small groups, who performed a laboratory task in about five hours. Two-level Hierarchical Linear Modeling (HLM) method was used. Results show the main effect from individual selfefficacy to satisfaction (both level 1), the cross-level effect from group cohesion (level 2) to individual satisfaction (level 1), and the interaction effect between self-efficacy and gender diversity to satisfaction. These results suggest that in a work group, satisfaction has a background in individual and group variables. Group cohesion and gender diversity have important effects on satisfaction. The article concludes with practical strategies and with limitations and suggestions for future research.

O presente relatório visa transmitir o trabalho desenvolvido ao longo de um ano de estágio profissionalizante, realizado no Club Sport Marítimo, tendo como propósito a conclusão do Mestrado em Treino Desportivo. Ao longo do período de estágio, o estagiário incorporou a equipa técnica da equipa de Juniores (Sub-18) do Clube, estando ainda presente em todos os eventos dinamizados pelo departamento de futebol amador. No entanto, a atividade de maior foco, foi a implementação e dinamização do Projeto Marítimo LAB, cujo objetivo passa pela avaliação e potencialização das características e capacidades dos jovens atletas do Clube. O Marítimo LAB abrangeu 241 atletas do género masculino, possuindo um intervalo etário entre os 10 e 18 anos de idade, sendo que após os momentos de avaliação e potencialização, analisou-se os dados obtidos no intuito de aferir a evolução dos atletas.

Este relatório teve como objetivo a sumarização das práticas realizadas de um estagiário na área de Observação e Análise de Jogo do Benfica Lab-Sport Lisboa e Benfica. Consiste neste trabalho a descrição das diversas tarefas operacionais e complementares realizadas por um estagiário na área já referida. Acrescendo a essas descrições, é apresentado em detalhe um estudo de investigação iniciado durante o processo de estágio, tendo sido todos os dados recolhidos nesse período e fornecidos quase exclusivamente pela área de observação e análise do Benfica Lab. Este estudo demonstrou existirem diferenças significativas em medidas de centralidade individuais (nível de intermediação numa rede social; influência numa rede social) da equipa A para a equipa B na mesma posição (posto especifico). A descrição detalhada de todo o processo envolvente à realização de uma conferência (relação com a comunidade), também está presente neste documento, evento esse que teve como seu principal objetivo demonstrar o “Processo de estágio Benfica Lab/ FMH – Observação e Análise de Jogo”.
