A study of team cohesion and player satisfaction in two face-to-face games

In this paper we investigate the link between game rules, team cohesion and players’ satisfaction with their teams within face-to-face team-based games. To measure team cohesion, rules from two games were analysed from the perspective of Social Identity Theory in order to form a hypothesis as to which game would be more likely to lead to more cohesive teams, where team cohesion is measured by the extent to which each player identifies with their team. Player satisfaction was measured by looking at three factors: communication within the team, player outcome versus team outcome, and fairness. Significant differences were found in the team cohesion measure suggesting that, as predicted by Social Identity Theory, team cohesion can be fostered by game rules. Team cohesion also correlated positively with player satisfaction. Taken together, this suggests that for games in which team cohesion is an important part, game designers can incorporate game rules in such as a way as to increase the likelihood of both team cohesion and player satisfaction

The relationship between game rules and team cohesion: an empirical study

Multiplayer games (both face-to-face and online) frequently feature teams. This study investigates whether it is possible to use the rules of a game to alter the team cohesion. Game rules from two face-to-face games were analyzed using Social Identity Theory to predict which will lead to more cohesive teams. Significant differences in team cohesion ratings given by the players after the games suggest that the game rules may indeed affect the team cohesion as predicted

Online outsiders within\ud

Heightened attention to technological diffusion and informational inequalities is of\ud particular societal concern, given the increasing mediation of everyday life whereby\ud web-based initiatives abound and an increasing amount of information on critical\ud human services including education and healthcare are online or only available online.\ud As Cheong and Martin (2009) note, the digital divide is a significant, multi-layered access\ud challenge for institutions of higher education worldwide as they embark on e or distance\ud learning programs, including the incorporation of virtual course management systems.\ud Kreps (2006) also notes that the digital divide is an important health communication\ud problem as new technologies can help underserved populations retrieve relevant health\ud information, yet exacerbate disparities by reducing access to those most at risk for poor\ud health outcomes

DNA polymerases required for repair of UV-induced damage in Saccharomyces cerevisiae

The ability of yeast DNA polymerase mutant strains to carry out repair synthesis after UV irradiation was studied by analysis of postirradiation molecular weight changes in cellular DNA. Neither DNA polymerase alpha, delta, epsilon, nor Rev3 single mutants evidenced a defect in repair. A mutant defective in all four of these DNA polymerases, however, showed accumulation of single-strand breaks, indicating defective repair. Pairwise combination of polymerase mutations revealed a repair defect only in DNA polymerase delta and epsilon double mutants. The extent of repair in the double mutant was no greater than that in the quadruple mutant, suggesting that DNA polymerases alpha and Rev3p play very minor, if any, roles. Taken together, the data suggest that DNA polymerases delta and epsilon are both potentially able to perform repair synthesis and that in the absence of one, the other can efficiently substitute. Thus, two of the DNA polymerases involved in DNA replication are also involved in DNA repair, adding to the accumulating evidence that the two processes are coupled

Issues of quality assurance in the management of plagiarism in blended learning environments

Increasing access to and availability of electronic resources presents students with a rich library of opportunities for independent study. But students also find themselves in the confusing territory of how they should best use these resources within their assessment activities. Likewise, teaching institutions are faced with the problems of plagiarism and collusion, and the challenges of educating, deterring, detecting, and dealing with breaches of policy in a fair and consistent way across all disciplines. This paper examines issues of quality assurance in the management of plagiarism by discussing the following questions: – How can effective automated plagiarism detection services be introduced and managed across the institution? – What teaching and assessment practices can be adopted to deter plagiarism? – What part should collusion and plagiarism detection tools play in educating and deterring students? – What are appropriate penalties for plagiarism and collusion and how can these be applied consistently across disciplines? Drawing together three distinct strands of research, in both distance and campus based institutions, the authors discuss how practice and policy have evolved in recent years in an attempt to reduce the incidence of plagiarism and collusion. The paper will illustrate this evolution by reporting on recent developments in assessment strategy, detection tools, and policy within two UK HE Institutions: The UK Open University and Manchester Metropolitan University

Pension funds' performance in strongly regulated industries in Central Europe: Evidence from Poland and Hungary

This paper presents an analysis of pension funds' performance in Poland and Hungary, two Central European countries characterized by strong regulation of their private pension fund industries. Thus, the paper extends the literature which has so far mostly focused on performance of pension fund industries facing no or limited regulation. We find that the performance of pension funds in the two studied countries differs. While we do not find convincing evidence of outperformance by Polish pension funds, we find strong evidence of underperformance by Hungarian pension funds. The results are robust to time-variation. The paper considers possible explanations behind these findings. The results of the paper should be of interest for policy-makers seeking to achieve optimal performance of the pension systems and academics in the research area of pension funds. --pension fund management,investment and performance regulation,performance measurement,Central European stock markets,Emerging Markets

The Nuclease Activity of the Yeast Dna2 Protein, Which Is Related to the RecB-like Nucleases, Is Essential in Vivo

Saccharomyces cerevisiae Dna2 protein is required for DNA replication and repair and is associated with multiple biochemical activities: DNA-dependent ATPase, DNA helicase, and DNA nuclease. To investigate which of these activities is important for the cellular functions of Dna2, we have identified separation of function mutations that selectively inactivate the helicase or nuclease. We describe the effect of six such mutations on ATPase, helicase, and nuclease after purification of the mutant proteins from yeast or baculovirus-infected insect cells. A mutation in the Walker A box in the C-terminal third of the protein affects helicase and ATPase but not nuclease; a mutation in the N-terminal domain (amino acid 504) affects ATPase, helicase, and nuclease. Two mutations in the N-terminal domain abolish nuclease but do not reduce helicase activity (amino acids 657 and 675) and identify the putative nuclease active site. Two mutations immediately adjacent to the proposed nuclease active site (amino acids 640 and 693) impair nuclease activity in the absence of ATP but completely abolish nuclease activity in the presence of ATP. These results suggest that, although the Dna2 helicase and nuclease activities can be independently affected by some mutations, the two activities appear to interact, and the nuclease activity is regulated in a complex manner by ATP. Physiological analysis shows that both ATPase and nuclease are important for the essential function of DNA2 in DNA replication and for its role in double-strand break repair. Four of the nuclease mutants are not only loss of function mutations but also exhibit a dominant negative phenotype

COMPARING THE IMPACTS OF RETIREE VERSUS WORKING-AGE FAMILIES ON A SMALL RURAL REGION: AN APPLICATION OF THE WISCONSIN ECONOMIC IMPACT MODELING SYSTEM

The Wisconsin Economic Impact Modeling System, a conjoined input-output/econometric model of Wisconsin counties, is used to simulate the economic and fiscal impact of two alternative residential development patterns. Under the first scenario, the impact of migrating retirees on a small tri-county region in northern Wisconsin is examined. Under the second scenario, the impact of the migration of younger families with children is examined. A comparison-contrast between the two scenarios demonstrates that the characteristics of the migrating household can have a significant impact on the nature of the impacts.Community/Rural/Urban Development,
