Adjusting to new work teams: Testing work experience as a multidimensional resource for newcomers

The successful performance adjustment of team newcomers is an increasingly important consideration given the prevalence of job‐changing and the uncertainty associated with starting work in a new team setting. Consequently, using sensemaking and uncertainty reduction theories as a conceptual basis, the present study tested work experience as a potential resource for newcomer performance adjustment in teams. Specifically, we tested work experience as a multidimensional predictor of both initial newcomer performance and the rate of performance change after team entry. We tested hypotheses using longitudinal newcomer performance data in the context of professional basketball teams. Although the traditional quantitative indicators of the length and amount of work experience were not meaningfully associated with newcomer performance adjustment, their interaction was. In addition, the qualitative indicator of newcomers' past transition experience revealed a significant, positive association with the rate of newcomer performance improvement following team entry. These results suggest that work experience is a meaningful facilitator of newcomer adjustment in teams and emphasize the dual consideration of both quantitative and qualitative work experiences. The theoretical and practical implications of these findings are discussed. Copyright © 2013 John Wiley & Sons, Ltd.

The U.S. Experience in Promoting Sustainable Chemistry (9 pp)

- Sustainable chemistry - Section editors: Klaus Günter Steinhäuser, Steffi Richter, Petra Greiner, Jutta Penning, Michael AngrickBackground, Aim and Scope Recent developments in European chemicals policy, including the Registration, Evaluation and Authorization of Chemicals (REACH) proposal, provide a unique opportunity to examine the U.S. experience in promoting sustainable chemistry as well as the strengths and weaknesses of existing policies. Indeed, the problems of industrial chemicals and limitations in current regulatory approaches to address chemical risks are strikingly similar on both sides of the Atlantic. We provide an overview of the U.S. regulatory system for chemicals management and its relationship to efforts promoting sustainable chemistry. We examine federal and state and examine lessons learned from this system that can be applied to developing more integrated, sustainable approaches to chemicals management.Main Features There is truly no one U.S. chemicals policy, but rather a series of different un-integrated policies at the federal, regional, state and local levels. While centerpiece U.S. Chemicals Policy, the Toxic Substances Control Act of 1976, has resulted in the development of a comprehensive, efficient rapid screening process for new chemicals, agency action to manage existing chemicals has been very limited. The agency, however, has engaged in a number of successful, though highly underfunded, voluntary data collection, pollution prevention, and sustainable design programs that have been important motivators for sustainable chemistry. Policy innovation in the establishment of numerous state level initiatives on persistent and bioaccumulative toxics, chemical restrictions and toxics use reduction have resulted in pressure on the federal government to augment its efforts.Results and Conclusions It is clear that data collection on chemical risks and phase-outs of the most egregious chemicals alone will not achieve the goals of sustainable chemistry. These alone will also not internalize the cultural and institutional changes needed to ensure that design and implementation of safer chemicals, processes, and products are the focus of the future. Thus, a more holistic approach of ‘carrots and sticks’ – that involves not just chemical producers but those who use and purchase chemicals is necessary. Some important lessons of the US experience in chemicals management include: (1) the need for good information on chemicals flows, toxic risks, and safer substances.; (2) the need for comprehensive planning processes for chemical substitution and reduction to avoid risk trade-offs and ensure product quality; (3) the need for technical and research support to firms for innovation in safer chemistry; and (4) the need for rapid screening processes and tools for comparison of alternative chemicals, materials, and products.

Prey detection without successful capture affects spider’s orb-web building behaviour

Animals obtain information from past foraging experience to adjust their foraging activity according to their environment. The ability of spiders to obtain information from unsuccessful predation experiences was investigated by examining the effects on web building, a significant foraging investment, of prey detection without successful capture in the orb-web spider Cyclosa octotuberculata. Four treatments were employed: (1) successful capture and feeding: one syrphid fly was allowed to be captured and consumed by the spider on the web; (2) single prey-item detection: a syrphid fly was placed on the web to lure the spider, but was removed before capture; (3) five prey-item detection: above prey-item detection stimulus was given five times; and, (4) control: neither prey nor feeding on the web. While control spiders decreased the total thread length and capture area of their webs, prey-item detection spiders in both conditions increased them, indicating that the spider obtained information from unsuccessful predation experience to adjust their foraging investment. The fed spiders exhibited a significantly greater increase than the prey-detection-only spiders, suggesting that prey detection alone and prey detection with consumption had different informational effects. Total thread length did not differ between single and five prey-item detection spiders, but distance between two adjacent sticky spirals increased only in the former spiders, possibly because five times unsuccessful predations prevented spiders to reduce web stickiness. It suggests that the spider changed web morphology according to the number of prey detection.
