Taking up physical activity in later life and healthy ageing: the English longitudinal study of ageing.

Abstract: Background Physical activity is associated with improved overall health in those people who survive to older ages, otherwise conceptualised as healthy ageing. Previous studies have examined the effects of mid-life physical activity on healthy ageing, but not the effects of taking up activity later in life. We examined the association between physical activity and healthy ageing over 8 years of follow-up. Methods Participants were 3454 initially disease-free men and women (aged 63.7±8.9 years at baseline) from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Self-reported physical activity was assessed at baseline (2002–2003) and through follow-up. Healthy ageing, assessed at 8 years of follow-up (2010-2011), was defined as those participants who survived without developing major chronic disease, depressive symptoms, physical or cognitive impairment. Results At follow-up, 19.3% of the sample was defined as healthy ageing. In comparison with inactive participants, moderate (OR, 2.67, 95% CI 1.95 to 3.64), or vigorous activity (3.53, 2.54 to 4.89) at least once a week was associated with healthy ageing, after adjustment for age, sex, smoking, alcohol, marital status and wealth. Becoming active (multivariate adjusted, 3.37, 1.67 to 6.78) or remaining active (7.68, 4.18 to 14.09) was associated with healthy ageing in comparison with remaining inactive over follow-up. Conclusions Sustained physical activity in older age is associated with improved overall health. Significant health benefits were even seen among participants who became physically active relatively late in life.

Toeholds, Bid Jumps, and Expected Payoffs in Takeovers

Abstract: We estimate sequentially outcome probabilities and expected payoffs associated with first, second, and final bids in a large sample of tender offer contests. Rival bids arrive quickly and produce large bid jumps. Greater bidder toeholds (prebid ownership of target shares) reduce the probability of competition and target resistance and are associated with both lower bid premiums and lower prebid target stock price runups. The expected payoff to target shareholders is increasing in the bid premium and in the probability of competition, but decreasing in the bidder's toehold. The initial bidder's expected payoff is significantly positive in the "rival-bidder-win" outcome, in part reflecting gains from the pending toehold sale. Despite these dramatic toehold effects, only half of the initial bidders acquire toeholds.

Contractual Governance, Relational Governance, and the Performance of Interfirm Service Exchanges: The Influence of Boundary-Spanner Closeness:

Abstract: Academics and managers are confronted with reconciling the social and economic aspects of business-to-business exchanges. In a service context, the authors investigate the relative importance of contractual and relational governance on exchange performance and the influence of the boundary spanner on the implementation of these governance mechanisms and on exchange performance. They test a model of the governance of commercial banking exchanges using interview data with both parties to the exchange (the account manager as the bank’s boundary spanner and the business client). Relational governance is the predominant governance mechanism associated with exchange performance. Contractual governance is also positively associated to exchange performance, but to a much lesser extent. The closeness of the account manager to the client company in terms of information gathering is also positively associated to exchange performance. However, this is mediated through both contractual and relational governance mechanisms with relational governance being the stronger mechanism.

Automatic recognition of handprinted characters—The state of the art

Abstract: Based on a study of the extensive literature in handprint recognition, this paper presents a survey in this challenging field. Recognition algorithms, data bases, character models, and handprint standards are examined. Achievements in the recognition of handprinted numerals, alphanumerics, Fortran, and Katakana characters are analyzed and compared. Data quality and constraints, as well as human and machine factors are also described. Characteristics, problems, and actual results on on-line recognition of handprinted characters for different applications are discussed. New emphases and directions are suggested.
