Relationships of providing and receiving leisure social support to stress in older adults

Leisure has become a topic of interest in stress-coping research. This study examined the relationships between receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence in older adults and their stress. A total of 639 community-dwelling older adults were recruited. Data were collected using face-to-face surveys, which included measures of leisure social support (receiving and providing), leisure self-determination, leisure competence and stress. Data were analysed using regression analysis. The results indicated that receiving leisure social support, providing leisure social support, leisure self-determination and leisure competence were significantly and negatively correlated with stress and that providing leisure social support was more significantly correlated with reduced stress than the other leisure factors. Implications of the results are discussed.     

The influence of attitudes towards healthy eating on food consumption when travelling

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group.     

A preliminary examination of the relationship between consumer attitude towards space travel and the development of innovative space tourism technology

With increasing global competition in service sectors, innovative technologies have radically changed the tourism industry, and to be successful innovative products/services must have clear, significant points of difference that are related to needs in the market place. Furthermore, changes in consumer perceptions that emanate from an innovation are central to its effective product and service design. Although for most of us space travel is still a faraway dream, it is in fact a future probability that will increasingly attract travellers who seek new vacation experiences, and as a result, sustain academic interest. Thus, in initiating space tourism for the purposes of recreation, leisure and knowledge enhancement, a preliminary estimation of potential global demand characteristics that are specific to consumer innovators for space travel needs to be undertaken prior to promotion of research and development. In this context, this paper investigates both consumer attitudes towards space travel by analysing the components of motivated consumer innovativeness and the interest that potential consumers have in developing space tourism technology innovations within Taiwan. Consumer innovativeness is complex and comprised four innovativeness types, namely, social, functional, hedonic and cognitive. As product/service innovation development has been relatively unexplored in the mature industry of tourism, many business managers would welcome an understanding of which vacation travellers are most likely to be the earliest buyers of such an exciting new product. With data collected from a sample of 354 Taiwanese, this research uses mediated regression to examine the influence of the four types of consumer innovativeness on consumer's attitudes and acceptance of a space tourism technology innovation, and the mediating role perceived novelty plays in the relationship. The findings indicate that only hedonic and social innovativeness are associated with improved consumer attitude and that novelty partially mediates the relationship for those two types of consumer innovativeness. The implications for theory and practice are discussed. Limitations and directions for future research are also addressed.     

Critical factors associated with relationship conflicts and group atmosphere among Taiwanese adolescents

This paper investigates relationship conflict amongst Taiwanese adolescents. The data was taken on Taiwanese adolescents aged 15–17 who attended 16 high schools which are located in north, middle, south, and the east of Taiwan. They were invited to participate in the study during the 2010 school year. This paper explores the patterns among relationship conflict including its impact, the social dimensions, the time aspects, the psychological implications, the physical dimensions, and the performance and overall risks involved in group atmospheres. The ways relationship conflict handling styles correlate with the group atmosphere were also explored. Each one of the risk variables’ correlations and relationship conflict were explored. As part of this study upon correlating each one of the risk variables and relationship conflict, the researchers studied the correlations between the risk variables and the group atmosphere.

浅论两汉时期河湟羌人的种姓家支制度

两汉时期的羌乱给汉王朝带来了巨大的灾祸,是促使东汉灭亡的因素之一。除了共同的政治经济利益使河湟各羌落凝聚起来反对汉王朝对羌民的歧视和苛政外,其本身存在已久的种姓家支制度亦使河湟羌落间始终有种潜在的联系,也正是这种制度使得徙入塞内上百年的羌人仍与塞外的羌落间有着相同的认知,促进羌落间的聚合。因此种姓家支制度是种潜在的凝聚机制。汉王朝亦认识到羌人家支制度对其统治产生的威胁,也有意识的予以破坏。     

应用ANSYS建立再生混凝土随机骨料模型的方法研究

通过对再生混凝土粗骨料成份的分析,初步提出将再生粗骨料大致分为以附着砂浆石子为主要成分并含有少量砂浆块和砖块杂质,并确定某批次再生粗骨料中各类骨料的百分含量。应用ANSYS的APDL参数化编程,结合蒙特卡罗方法和富勒级配理论,从细观层次上生成再生混凝土各类骨料的二维圆形与三维球形随机骨料模型,并赋予各类骨料的材料属性。然后根据选定的单元类型进行有限元网格的划分,通过判断各单元与骨料形心的位置关系来识别砂浆基质与骨料之间的界面单元,并赋予它相应的材料属性。从而建立起再生混凝土的数值模拟试件,为今后在ANSYS中直接对其进行加载求解,以此来模拟各种力学性能试验提供了必要的基础。     

Revisiting the relationship between suicide and unemployment: Evidence from linear and nonlinear cointegration

This study employs the linear and nonlinear ARDL cointegration methodologies to examine the potential symmetric and asymmetric responses of suicide rates to unemployment rates in the US from 1928 to 2013. Our results suggest that suicide rates are pro-cyclical with respect to the business cycle (measured by changes in the unemployment rate) after extensively controlling for divorce and fertility rates. Unemployment has symmetric long-run effects on the age-adjusted suicide rate and four age-specific (from ages 25–34 to 55–64) suicide rates, while the effect of an economic expansion on suicide rates for those aged over 45 is greater than the effect of an economic recession. These findings imply that the effect of an economic expansion on the decrease of the suicide rate is higher than the effect of an economic recession on the increase of the suicide rate for individuals aged over 45. Therefore, intervention designed to reduce suicidal behaviors should emphasize periods of economic recession more than periods of economic expansion for those of middle age and beyond.
