The increasing importance of information technology (IT) services in the global economy prompts researchers in the field of information systems (IS) to give special attention to the foundations of managerial and technical knowledge in this emerging arena of knowledge. Already we have seen the computer science discipline embrace the challenges of finding new directions in design science toward making services-oriented computing approaches more effective, setting the stage for the development of a new science - service science, management, and engineering (SSME). This paper addresses the issues from the point of view of service science as a fundamental area for IS research. We propose a robust framework for evaluating the research on service science, and the likely outcomes and new directions that we expect to see in the coming decade. We emphasize the multiple roles of producers and consumers of services-oriented technology innovations, as well as value-adding seller intermediaries and systems integrators, and standards organizations, user groups, and regulators as monitors. The analysis is cast in multidisciplinary terms, including computer science and IS, economics and finance, marketing, and operations and supply chain management. Evaluating the accomplishments and opportunities for research related to the SSME perspective through a robust framework enables in-depth assessment in the present, as well as an ongoing evaluation of new knowledge in this area, and the advancement of the related management practice capabilities to improve IT services in organizations. © 2010 M.E.

The role of the counterion in the overall structure of the coordination networks formed between 1,2-bis(3′-quinolinyl)ethyne and six silver(I) salts is highlighted. The coordinating ability of the anion dominates the structures which fall into two major categories: (a) Type A, essentially planar one dimensional ribbons formed from salts with non-coordinating anions like tetrafluoroborate and hexafluoroantimonate or the weakly coordinating anion trifluoromethanesulfonate; and (b) Type B, anion bridged duplex, or double-stranded, linear ribbons formed with the coordinating anions trifluoroacetate and pentafluoropropionate as well as nitrate. π-stacking is important in the three dimensional inter-strand packing of both types of coordination polymers. © The Royal Society of Chemistry 2011.

PURPOSE: The current study examined the relationship between children's performance on the Progressive Aerobic Cardiovascular Endurance Run subtest of the FitnessGram® and aspects of cognitive control that are believed to support academic success. METHODS: Hierarchical linear regression analyses were conducted on a sample of second-and third-grade children (n = 397) who completed modified versions of a flanker task and spatial n-back task to assess inhibitory control and working memory, respectively. RESULTS: Greater aerobic fitness was significantly related to shorter reaction time and superior accuracy during the flanker task, suggesting better inhibitory control and the facilitation of attention in higher-fit children. A similar result was observed for the n-back task such that higher-fit children exhibited more accurate target detection and discrimination performance when working memory demands were increased. CONCLUSIONS: These findings support the positive association between aerobic fitness and multiple aspects of cognitive control in a large sample of children, using a widely implemented and reliable field estimate of aerobic capacity. Importantly, the current results suggest that this relationship is consistent across methods used to assess fitness, which may have important implications for extending this research to more representative samples of children in a variety of experimental contexts. © 2014 by the American college of Sports Medicine.

When a customer interacts with a firm, extensive personal information often is gathered without the individual's knowledge. Significant risks are associated with handling this kind of information. Providing protection may reduce the risk of the loss and misuse of private information, but it imposes some costs on both the firm and its customers. Nevertheless, customer information security breaches still may occur. They have several distinguishing characteristics: (1) typically it is hard to quantify monetary damages related to them; (2) customer information security breaches may be caused by intentional attacks, as well as through unintentional organizational and customer behaviors; and (3) the frequency of such incidents typically is low, although they can be very costly when they occur. As a result, predictive models and explanatory statistical analysis using historical data have not been effective. We present a profit optimization model for customer information security investments. Our approach is based on value-at-risk methods and operational risk modeling from financial economics. The main results of this work are that we: (1) provide guidance on the trade-offs between risk and return in customer information security investments; (2) define the range of efficient investments in technology-supported risk indemnification for sellers; (3) model how to handle government-dictated levels of investment versus self-regulation of investments in technology; and (4) characterize customer information security investment levels when the firm is able to pass some of its costs on to consumers. We illustrate our theoretical findings with empirical data from the Open Security Foundation, as a means of grounding our analysis and offering the reader intuition for the managerial interpretation of our theory and main results. The results show that we can narrow the decision set for solution providers and policy-makers based on the estimable risks and losses associated with customer information security. We also discuss the application of our approach in practice. © 2011 Elsevier B.V. All rights reserved. Source

The remains of Terminal Pleistocene megafauna in North America represent a continent-wide case study in understanding the taphonomic processes that affect bones, and the use and reuse of bones among some of North America's earliest inhabitants. The complex dynamics of bone fracture, bone degradation, and the effects of natural and cultural taphonomic processes present a challenge for interpreting the nature of fractured and fragmented zooarchaeological material in North America. The role of the environment in affecting bones and their suitability for use and reuse is profound. Natural processes affect the preservation of bones and their suitability for use, which presents an interpretive challenge for archaeologists examining fractured and fragmented remains. This paper seeks to explain, describe, and resolve some of the problems inherent in assessing and understanding the use and reuse of bones as raw materials, using evidence from two Terminal Pleistocene sites in North America (Owl Cave in Idaho, and the Inglewood site in Maryland) as case studies that highlight the cultural, environmental, and interpretive differences that are manifest in zooarchaeological (and paleontological) assemblages. © 2015.
