As a measure of cold hardiness, we tested the supercooling points or freezing temperatures of individual hemlock woolly adelgids (Adelges tsugae Annand) collected from 15 locations across the north to south range of the adelgid in eastern North America at different times during two winters. Adelgids from the northern interior locations with USDA hardiness zones of 5B-6B had lower supercooling p...

Although many people suffer physical and mental health decrements following exposure to stress, many others show remarkable resilience, remaining healthy despite high stress levels. If the factors that account for resilience can be clearly identified and understood, perhaps resilience can be enhanced even for those most vulnerable to stress. One potential pathway to resilience is personality ha...

Winter-diapause and cold-acclimated non-diapause pupae of the onion maggot, Delia antiqua (Diptera: Anthomyiidae), show strong cold hardiness. To obtain insights into the mechanisms involved in the enhancement of cold hardiness, we investigated the expression patterns of genes encoding subunits of chaperonin (CCT) and the morphology of actin, a substrate of CCT, at low temperatures. Quantitativ...

It has been hypothesized that the increase in temperature in this century could lead to an increase in frost damage to plant tissues. Several models have been proposed to describe the development of cold hardiness, but never taking into account extreme climatic and/or physiological events. Our results on walnut tree (Juglans regia L.) show that cold hardiness was best correlated with average da...

conclusions the results of the present study give some evidence that allows us to conclude that hardiness and coping strategies affect occupational life quality for both people suffering from type ii diabetes and healthy people. therefore, it is proposed that people strengthen their hardiness and coping strategies, in order to improve their occupational life quality. background due to the epide...

objective: psychological hardiness is a protective personality structure against life stresses that plays a major role in resisting stressful events. thus, the present research aimed to predict the psychological hardiness based on mental health and emotional intelligence in students. methods: the method applied in the research was a descriptive-correlation type. a total of 348 students of payam...

OBJECTIVES Recent evidence suggests that suicidal ideation is increased among university students, it is essential to increase our knowledge concerning the etiology of suicidal ideation among university students. This study was conducted to examine the relationships between problem-solving skills appraisal, hardiness, and suicidal ideation among university students. In addition, this study was ...

A great number of research suggests that hardiness acts as a protective factor in stressful situations, especially in work context. In the present research the factor structure of Dispositional Resilience Scale (DRS; Bartone, Ursano, Wright, & Ingraham, 1989), and its factorial invariance across gender was examined. Furthermore, the relationships of hardiness to five-factor personality traits a...

Although the aging literature suggests that there are many paths to later life adjustment, there have been few empirical attempts to identify different patterns of adaptation, or their relation to adaptive outcome. As a way to identify patterns of socioemotional functioning in later life associated with physical hardiness, a cluster analysis was applied to 11 measures of socioemotional function...
