Group vitality is a widely invoked construct in the study of minority language maintenance and interethnic relations. Per the original framework introduced 40 years ago, the more vitality an ethnolinguistic group perceives itself to have, the more likely that it will thrive as a collective entity in an intergroup context. Consequently, research adopting this paradigm—herein termed vitality theory—has studied ways in which objective and subjective group vitality has manifested itself in the endurance of ethnolinguistic groups. The notion of objective vitality includes the factors of demographics, institutional support, and status that characterize the strength of a group in comparison to others present in an intergroup setting. Contrastively, subjective vitality was introduced to highlight how groups may cognitively and affectively perceive these same factors. A large body of empirical research has been conducted within the vitality theory framework that has resulted in several stages of development. Evidence has shown that while the components of objective vitality (demographics, institutional support, status) do not typically manifest themselves as distinct components in the structure of subjective vitality, they do form a single component reflecting the perceived strength of the group. In addition, several other social psychological factors, such as perception of the legitimacy of intergroup relations, the level of ethnocentrism, and perception of intergroup distance, were incorporated into models of subjective vitality. Relatedly, these factors are shaped into group members’ discourse of vitality, which is a highly dialogical process of negotiation of subjective vitality of the groups engaged in intergroup contact. The vitality framework has been usefully invoked beyond ethnolinguistic groups, embracing several intergroup settings including age, gender, and sexual orientation. Vitality, which has provoked some controversy in the literature, has also been widely adopted by very different approaches as an umbrella term to denote the long-term sustainability of a group. Scholars in linguistics, sociology, psychology, education, anthropology, and beyond have contributed much to the concept, helping to educate and raise awareness as to why languages die out and the effects of such languages dying out.

This chapter reviews social psychological research on help giving and helping relations from the 1950s until today. The first section considers the conditions under which people are likely to help others, personality dispositions that characterize helpful individuals, and motivational and attributional antecedents of helpfulness. The second section looks at long-term consequences of help and examines help in the context of enduring and emotionally significant relationships. Research has shown that in the long run help can increase psychological and physical well-being for helpers but discourage self-reliance for recipients. The third section analyzes helping from intra- and intergroup perspectives, considering how its provision can contribute to helpers’ reputations within a group or promote the positive social identity of in-groups relative to out-groups. Help is thus conceptualized as a negotiation between the fundamental psychological needs for belongingness and independence. Theoretical and practical implications are discussed.

Abstract Background International guidelines recommend brachytherapy for patients with dysphagia from esophageal cancer, whereas brachytherapy is infrequently used to palliate dysphagia in some countries. To clarify the availability of palliative treatment for dysphagia from esophageal cancer and explain why brachytherapy is not routinely performed are unknown, this study investigated the use of brachytherapy and external beam radiotherapy for dysphagia from esophageal cancer. Methods Japanese Radiation Oncology Study Group members completed a survey and selected the treatment that they would recommend for hypothetical cases of dysphagia from esophageal cancer. Results Of the 136 invited facilities, 61 completed the survey (44.9%). Four (6.6%) facilities performed brachytherapy of the esophagus, whereas brachytherapy represented the first-line treatment at three (4.9%) facilities. Conversely, external beam radiotherapy alone and chemoradiotherapy were first-line treatments at 61 and 58 (95.1%) facilities, respectively. In facilities that performed brachytherapy, the main reason why brachytherapy of the esophagus was not performed was high invasiveness (30.2%). Definitive-dose chemoradiotherapy with (≥50 Gy) tended to be used in patients with expected long-term survival. Conclusions Few facilities routinely considered brachytherapy for the treatment of dysphagia from esophageal cancer in Japan. Conversely, most facilities routinely considered external beam radiotherapy. In the future, it will be necessary to optimize external beam radiotherapy.

AbstractOn the basis of investigations with samples from a fertilization trial started in 1980, some parameters of food storage ability are evaluated. Microbial infestation of the product during incubation seems to be the most reliable parameter, but the circumstances of infestation and the optimal test conditions are unknown. There are no reliable correlations among the results of degradation tests, storage tests under optimal conditions, and chemical contents of the product. The concept of product vitality (a product-oriented quality referring to a product full of vigor) is based on results of degradation tests. Ultimately, however, food quality standards are based on human priorities (human-oriented). Therefore, not only product characteristics, but also social, psychological, and environmental criteria should be considered.

Sixty years ago, the notion that animals could have culture was unthinkable to most behavioral scientists. Today, evidence for innovation, transmission, acquisition, long-term maintenance, and intergroup variation of behavior exists throughout the animal kingdom. What can the longitudinal and comparative study of monkeys handling stones tell us about how culture evolved in humans? Now in its 30th year, the systematic study of stone-handling behavior in multiple troops of Japanese macaques has shown that socially mediated learning is essential to explain the spread, persistence, and transformation of individual behavioral innovations among group members. The integrative research paradigm presented here can be applied to the study of various candidate behavioral traditions in other species.

SUMMARYThe effects of long-term fasting and subsequent refeeding on digestive physiology and energy metabolism were investigated in a subterranean aquatic crustacean, Stenasellus virei, and in a morphologically similar surface-dwelling species, Asellus aquaticus. Metabolic response to food deprivation was monophasic in A. aquaticus, with an immediate,large decrease in all energy reserves. In contrast, S. vireidisplayed three successive periods of phosphageno-glucidic, lipidic and,finally, proteo-lipidic-dominant catabolism over the course of the nutritional stress. To represent the responses of subterranean crustaceans to food stress and renutrition, a sequential energy strategy was hypothesized, suggesting that four successive phases (called stress, transition, adaptation and recovery) can be distinguished. Based on these results, a general adaptive strategy for groundwater organisms was proposed. Their remarkable resistance to long-term fasting may be partly explained by (1) a depressed metabolism,during which they mainly subsist on lipid stores, (2) a prolonged state of glycogen- and protein-sparing, (3) low energetic requirements and (4) large body stores. In addition, these groundwater species displayed high recovery abilities during refeeding, showing an optimal utilization of available food and a rapid restoration of their body reserves. These adaptive responses might be considered for numerous subterranean organisms as an efficient energy-saving strategy in a harsh and unpredictable environment where fasting(and/or hypoxic) periods of variable duration alternate with sporadic feeding events (and/or normoxic periods). Therefore, food-limited and/or hypoxia-tolerant groundwater species appear to be good examples of animals representing a low-energy system.

Aging is a function of time and is a natural and integral part of the life cycle. Aging process differs among individuals and brings all kinds of changes, affecting not just the physical body and its functions, but also to the social, psychological and financial situations to individuals. Aging in place (AIP) is a common preference among older people for remaining in their local community and maintaining their social networks throughout the aging process. Issues about appropriateness of aging in place, long-term care, and residential homes are discussed. Some models and recommendations are discussed, completed with thoughts on future studies.

Solitary confinement subjects prisoners to extreme forms of social isolation and social exclusion that, in turn, produce very high levels of suffering and pathology and nearly unprecedented degrees of loneliness. This chapter briefly reviews the scientific literature on harmful effects of solitary confinement, connecting it more directly to social psychological research on the adverse effects of social exclusion and isolation. The author discusses findings from a recent study of loneliness among long-term isolated prisoners, as well as an earlier study performed in an especially harsh solitary confinement unit—the Security Housing Unit (SHU) at the Pelican Bay State Prison in California—which systematically assessed the prevalence of symptoms of psychological stress, trauma, and isolation-related psychopathology.
