Characteristics of Older Adult Problem Gamblers Calling a Gambling Helpline

Background Few investigations have characterized groups of older adults with gambling problems, and published reports are currently limited by small samples of older adult problem gamblers. Gambling helplines represent a widespread mechanism for assisting problem gamblers to move into treatment settings. Given data from older adult problem gamblers in treatment, we hypothesized that older as compared with younger adult problem gamblers calling a gambling helpline would be less likely to report gambling-related problems.Design and methods Logistic regression analyses were performed on data obtained from January 1, 2000 to December 31, 2001, inclusive, from callers with gambling problems (N = 1,084) contacting the Connecticut Council on Problem Gambling Helpline.Results Of the 1,018 phone calls used in the logistic regression analyses, 168 (16.5%) were from older adults and 850 (83.5%) from younger adults. Age-related differences were observed in demographic features, types and patterns of gambling reported as problematic, gambling-related problems and psychiatric symptoms, substance use problems, patterns of indebtedness, and family histories of addictive disorders. Older as compared with younger adult problem gamblers were more likely to report having lower incomes, longer durations of gambling, fewer types of problematic gambling, and problems with casino slot machine gambling and less likely to report gambling-related anxiety, family problems, illegal behaviors and arrests, drug problems, indebtedness to bookies or acquaintances, family histories of drug abuse, and problems with casino table gambling.Conclusions Older as compared with younger adult problem gamblers calling a gambling helpline differ on many clinically relevant features. The findings suggest the need for improved and unique prevention and treatment strategies for older adults with gambling problems.     

论我国目前行政问责制的突出问题及对策探微

目前我国在行政问责制方面还存在一些问题:行政问责的范围不清、对象不明确;行政问责的主体缺位、有名无实;行政问责的法律体系不健全、无程序性。因此,有必要寻求问责制之出路:规范行政问责原则;明确行政问责范围;健全行政问责法律;强化行政问责意识。     

新农村殡葬改革问题探讨

当前在农村殡葬改革中存在着铺张浪费、"以罚代葬"、基础设施不完善等问题。各级政府要抓住建设社会主义新农村的机遇,加大殡葬改革的资金投入,克服困难,完善新农村殡葬改革。     

再论耕地资源的保护

耕地是人类社会生产和生活的基础。我国耕地资源的保护对本民族生存和国民经济的发展以及我国农业可持续发展战略具有重要意义。目前，人们对耕地资源保护在认识、技术、投入等方面存在着不同程度的问题。针对这些问题应采取思想教育、法律、行政、技术等综合措施，以保护耕地资源的数量、质量和生态系统。     

以党的自我革命引领社会革命的时代意蕴与实践取向

深刻认识与把握“以党的自我革命引领社会革命”这一重大命题,首先要有效破题。破解这一重大理论与实践命题,必须坚持问题导向、目标导向与实践取向,聚焦新时代、新问题、新矛盾、新要求;必须结合全面从严治党、解决大党独有难题来深刻认识党的自我革命作为跳出治乱兴衰历史周期率的“第二个答案”的当代意蕴,根据“四自”基本内涵深刻把握新时代党的自我革命的内在逻辑与时代要求;必须深刻认识两种性质、两种类型的社会革命,结合全面建设社会主义现代化国家的新任务新要求来深刻认识社会革命的当代意蕴;必须从“改造主体世界与改造客体世界”基本逻辑出发,以党的建设、党的领导、党的事业相统一为基本分析范式,深刻把握以党的自我革命引领社会革命的当代意蕴、现实要求与实践机制。     

供应链间的竞争与协调合同设计研究

近来年,经济全球化环境中的市场竞争,越来越体现在市场中供应链之间的竞争。因此,运用News-vendor模型和博弈论方法,从行业协会角度研究竞争情况下不同供应链间在批发价合同、回购合同、收益共享合同、数量弹性合同和销售折扣合同下的协调条件,可以为通过行业协会协调增加各方利润,提供协调供应链的具体方式,从而得到协调两条供应链的合同设计方法。     

Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.     

Newsvendor Problems with Demand Shocks and Unknown Demand Distributions

In today's competitive market, demand volume and even the underlying demand distribution can change quickly for a newsvendor seller. We refer to sudden changes in demand distribution as demand shocks. When a newsvendor seller has limited demand distribution information and also experiences underlying demand shocks, the majority of existing methods for newsvendor problems may not work well since they either require demand distribution information or assume stationary demand distribution. We present a new, robust, and effective machine learning algorithm for newsvendor problems with demand shocks but without any demand distribution information. The algorithm needs only an approximate estimate of the lower and upper bounds of demand range; no other knowledge such as demand mean, variance, or distribution type is necessary. We establish the theoretical bounds that determine this machine learning algorithm's performance in handling demand shocks. Computational experiments show that this algorithm outperforms the traditional approaches in a variety of situations including large and frequent shocks of the demand mean. The method can also be used as a meta‐algorithm by incorporating other traditional approaches as experts. Working together, the original algorithm and the extended meta‐algorithm can help manufacturers and retailers better adapt their production and inventory control decisions in dynamic environments where demand information is limited and demand shocks are frequent
