Cognitive fitness

Recent neuroscientific research shows that the health of your brain isn't, as experts once thought, just the product of childhood experiences and genetics; it reflects your adult choices and experiences as well. Professors Gilkey and Kilts of Emory University's medical and business schools explain how you can strengthen your brain's anatomy, neural networks, and cognitive abilities, and prevent functions such as memory from deteriorating as you age. The brain's alertness is the result of what the authors call cognitive fitness -a state of optimized ability to reason, remember, learn, plan, and adapt. Certain attitudes, lifestyle choices, and exercises enhance cognitive fitness. Mental workouts are the key. Brain-imaging studies indicate that acquiring expertise in areas as diverse as playing a cello, juggling, speaking a foreign language, and driving a taxicab expands your neural systems and makes them more communicative. In other words, you can alter the physical makeup of your brain by learning new skills. The more cognitively fit you are, the better equipped you are to make decisions, solve problems, and deal with stress and change. Cognitive fitness will help you be more open to new ideas and alternative perspectives. It will give you the capacity to change your behavior and realize your goals. You can delay senescence for years and even enjoy a second career. Drawing from the rapidly expanding body of neuroscience research as well as from well-established research in psychology and other mental health fields, the authors have identified four steps you can take to become cognitively fit: understand how experience makes the brain grow, work hard at play, search for patterns, and seek novelty and innovation. Together these steps capture some of the key opportunities for maintaining an engaged, creative brain.     

Predictors of registered nurses' willingness to remain in nursing

A major question about the adequacy of the future supply of nurses is how many will stay in the profession. The relationship between scheduling and propensity to stay or leave the nursing profession was examined in this study. This analysis suggests there are definite characteristics of the work schedules that can influence a nurse's inclination to stay or leave the profession. This is not simply a question of "overwork," but of matching work schedules and hours as closely as possible to employee expectations. This suggests management needs to find a way to pay attention when nurses request changes in hours. The mere fact of changing schedules will not solve the nursing shortage, but it is one action within the management control of any organization employing nurses that could have a positive effect on retention.     

并购交易中的金降落伞计划

对于即将奔赴海外进行并购的中国企业而言,必须仔细审视这些“金降落伞”计划是否会加大收购成本或增加目标公司现金支出从而阻碍购并。     

使比较研究可信

:人们在进行宏观社会现象的研究时,方法上有定性与定量之分。定量分析呈现U字形分布,对极少量的N进行研究有案例分析导向,对极大量的N进行研究不利于认识的深化,因此有必要寻找案例研究与变量导向研究之间的中间路线。组合式研究就有很多独特的优点。     

旅游地文化空间及其演化机理

旅游活动的文化属性决定了旅游地本质上是为旅游者提供一个文化空间。从旅游地文化的空间研究转向空间的文化研究,并厘清旅游地文化空间的内涵及其演化机理,寻求旅游地的文化发展规律,有助于解决旅游规划与开发中"造文化、造景观"的困境。基于空间生产和景观生态学原理,以及旅游地文化空间的活态性,旅游地文化空间的时间和功能演化是由原居民的生产与生活空间演变为服务于旅游发展的生产与生活空间的过程。旅游地文化空间在形态上,则表现为文化节点、文化轴线、文化场、文化域面等基本空间形态的形成与演化。文化场作为最为重要的空间形态,它是旅游地进行生产、生活与服务的真实场景,体现了人与旅游景观的社会文化关系。
