Determining the fitness consequences of sibling interactions is pivotal for understanding the evolution of family living, but studies investigating them across lifetime are lacking. We used a large demographic dataset on preindustrial humans from Finland to study the effect of elder siblings on key life-history traits. The presence of elder siblings improved the chances of younger siblings surv...

The results of the first national incidence study of noninstitutionalized elder abuse and neglect in the United States are reviewed, as well as underlying causes of abusive relationships involving the elderly. It is estimated that approximately 1% to 2% of elders living in their own homes became abused in the United States during 1996, physically, emotionally, sexually, and/or financially. The ...

Let M be a simply connected complex submanifold of C . We prove that M is irreducible, up a totally geodesic factor, if and only if the normal holonomy group acts irreducibly. This is an extrinsic analogue of the well-known De Rham decomposition theorem for a complex manifold. Our result is not valid in the real context, as it is shown by many counter-examples.

Since their inception, social networking sites (SNSs) have experienced exponential growth. While substantial research has been dedicated to users’ initial adoption of SNSs, the fall of MySpace reminds us that the long-term success of SNSs depends on users’ post adoption staying power. Inspired by this, this work-in-progress investigates users’ “stickiness” with a specific SNS. Based on Li et al...

This paper reports on an empirical investigation of the relationship between print and hypertext reading skills. Subjects in the study were university students at a public Midwestern university. A repeated-measures, counter-balanced design was employed. Subjects were categorized as highand low-ability readers based on a standardized measure of reading achievement. Experimental tasks required su...

Content contribution from individuals is critical to the viability of online communities. In this study we identify the factors that are associated with the quantity and the quality of content sharing in a photo sharing community, where the act of content creation is decoupled from the act of content sharing. We draw on theories of intrinsic and extrinsic motivation, and find that the prospect ...

To determine longitudinal risk factors for elder abuse and neglect, an established cohort of community-dwelling older adults (n = 2,812) was linked with elderly protective service records over a 9-year follow-up period. Protective services saw 184 (6.5%) individuals in the cohort for any indication, and 47 cohort members were seen for corroborated elder abuse or neglect for a sampling adjusted ...

The elder people of age band 65 to 75 are more prone to falling. Most of falling occur accidentally without consciousness. It can cause serious disorders and aftermath health issues for elderly people. For people with Alzheimer’s disease, this could be even disastrous. Palliative care includes detection of fall of the elderly and treating them at the right time. This detection can be improved f...

Today most people in America are living longer than at any previous time in our history. Medical technology, more knowledge concerning nutrition and healthy lifestyles contribute to a longer life span. Regrettably, resources such as services geared specifically for the elderly have not increased or are increasing at a slower pace than needed (Griffin & Williams, 1992). Baron and Welty (1996) ci...
