Conflict between software testers and developers is inevitable, but mindful managers minimize its effect on development projects through communication, mutual respect, even social interaction.

Pair Programming is an innovative collaborative software development methodology. Anecdotal and empirical evidence suggests that this agile development method produces better quality software in reduced time with higher levels of developer satisfaction. To date, little explanation has been offered as to why these improved performance outcomes occur. In this qualitative study, we focus on how individual differences, and specifically task conflict, impact results of the collaborative software development process and related outcomes. We illustrate that low to moderate levels of task conflict actually enhance performance, while high levels mitigate otherwise anticipated positive results.

A case report is presented of an unusual occurrence of peripheral facial nerve paresis owing to isolated perineurial extension from a cutaneous squamous cell carcinoma. Current evidence dispels the previously held belief that perineural invasion and extension occurs in lymphatic spaces. The clinical importance of recognizing this route of spread by tumors of the head and neck is discussed.

In this paper, weuse game theory to understand decisions tocooperate orto compete in thedelivery ofpublic health services. Health care isa quasi-public good that isoften associated with altruistic behavior, yet it operates in an increasingly competitive environment. With mounting health care regulation and changes in privatization, altruistic arguments give wayto more competitive rationales for market decisions. Profit and not-for-profit institutions must address widespread health care needs while balancing theneeds of more lucrative markets against theneeds of lesser ones. Recognizing the roles ofcooperation andcompetition as motivators in thedelivery ofhealth care to thepublic is imperative. We explore two game theory models (Nash's Equilibrium andthePrisoner's Dilemma) andtheir related concepts of simultaneous interdependence and rationality to examine decision-making. Four hypothetical public health case studies are presented. We conclude thatunderstanding game theory andthefactors influencing decisionmaking allows potential competitors to make more efficient decisions, including decisions to cooperate or compete. Aspublic health agencies move toward more collaborative models ofservice delivery, such understanding mayhelp enhance efficient andeffective service delivery.
