Independent Effects

In animals, social organisation and behaviour can respond to variation in key ecological factors including population and resource density. As these two factors covary, their relative importance is difficult to estimate using field studies. Consequently, we conducted two manipulative experiments varying levels of either population or shelter density to separate their effects on solitary, affiliative and agonistic behaviour and physiology in the social tree skink, Egernia striolata. We used focal observations and plasma concentrations of the hormone corticosterone to measure behavioural and physiological responses to these manipulations. Aggressive behaviours occurred more frequently at high skink density, with males at high density exhibiting social stress, as indicated by increased levels of corticosterone. Skinks at low densities showed greater affiliative behaviour, spending more time basking as pairs. Changes in shelter density influenced exploratory behaviours, with males at low shelter densities exploring enclosures more than those at high shelter densities. Skinks sheltered as pairs more frequently at low shelter density, even after taking into account differences in frequency of pair sheltering expected by chance alone, suggesting that low shelter availability promotes pair behaviour. Corticosterone levels increased over time at low shelter density, which may have been a result of thermal stress coupled with a lack of microclimate variation in comparison to high shelter density. These results suggest that population and resource density are key factors that can independently influence social behaviour and endocrinology, and consequently social organisation, in different ways.

The problems of this study are 1) What is the role BAPAS of prisoners who have gained parole? 2) Any constraints faced by BAPAS in conducting guidance to inmates who obtain parole? The method used in this study using qualitative analysis, that takes into account the facts that exist in the field of practice which are then compared with the description obtained from the study of literature. From this analysis it can be seen the effectiveness of the criminal system that is instructive to the child as a criminal. Data obtained from both primary data and secondary data then analyzed qualitative diskritif troubleshooting procedures examined by exposing data have been obtained from the library studies and field studies were analyzed with the form of conclusions. The results using this sociological juridical methods conclude that: 1) Implementation guidance is felt still far from the expectations of the client, because the guidance conducted by the social counselor counsels are only just so monotonous at all. Whereas in the implementation of the Directive No. E-39-PR.05.03 of 1987 regarding Correctional Client Guidance was mentioned about the forms of activity, so that what has been a guide in the implementation of forms of activity can not run properly, 2).Constraints can be divided into two factors, namely the constraints caused by internal factors and constraints caused by external factors. As the constraints caused by the internal factor is the perception that the client to obtain a conditional release will apply to both the public, As for the problems caused by external factors is the client's premises much an obstacle for the client to do a report that it was his duty, so sometimes it is supervising the relevant social grant a dispensation for the client to do the report at a certain time.Keywords: Strategy; Correctional Centers (BAPAS) Non-Conditional.

Proximate Determinants

AbstractWhile field studies of wild chimpanzees have investigated the proximate determinants of hunting success, little attention has been paid to the decision to hunt. We present evidence from Gombe National Park, Tanzania, showing that the social factors that most strongly influence the decision to hunt red colobus monkeys are the presence of female chimpanzees with anogenital sexual swellings in the foraging party, the number of adult and adolescent males in the party, and the total size of the foraging party. Of these, the presence of one or more swollen females was the best predictor of a decision to undertake hunts of red colobus groups at all but the smalles chimpanzee foraging party size. Two likely explanations for this pattern are discussed. First, swollen females may be a primary influence on male grouping patterns, which in turn promotes hunting. Second, this finding, together with previous research showing that male chimpanzees preferentially give meat to estrous females, suggests that male chimpanzee hunting performance may be under sexual selection. While nutritional and ecological factors may influence chimpanzee hunting patterns at times, chimpanzees appear to hunt red colobus at least partially to obtain meat for use as a social and reproductive tool.

The paper is devoted to ethno-cultural landscapes of the Republic of Tuva. Ethnocultural landscapes (ECLs) are specific socio-environmental systems that developed as a result of the interaction of ethnic groups with their natural and social environments and are in a constant process of transformation. An attempt is made to identify the mechanisms of the formation, functioning and dynamics of ethnocultural landscapes in the specific conditions of the intracontinental cross-border mountain region, as well as to establish the main factors-catalysts of their modern changes. For the first time an attempt is made to delimit and map the ethnocultural landscapes of Tuva. For this, literary sources, statistical data and thematic maps of different times are analyzed using geoinformation methods. The results of 2014-2018 field studies are also used, during which interviews with representatives of different ethno-territorial, gender, age and social groups were taken. It is revealed that the key factors of Tuva’s ethnocultural landscape genesis are the natural isolation of its territory; the features of its landscape structure; the role of government; population migrations from other regions and the cultural diffusion provoked by them. 13 ethnocultural landscapes are identified at the regional level. Their modern transformation is determined by the shift of climatic cycles, aridisation, globalisation of sociocultural processes, changes in economic specialisation and ethnopsychological stereotypes.

Typical Model

Drastic transformations of the social and labor sphere have led to the emergence of new health risks and sanitary and hygienic problems associated with unreliability of employment. A new socio-economic and psychological phenomenon “precarity” has emerged, which has aff ected the employment conditions of employees, so the description of the phenomenon “precarity” needs to be clarifi ed.The forms of labor employment that diff er from the typical model and worsen the employee’s situation are considered. The criteria based on which non-standard employment is considered unstable are given.Generalized types of unstable employment are identifi ed, the specifi city of which is determined by a combination of two factors: working time and the term of the contract. Unstable working conditions are possible not only in informal employment, but also in legal labor relations. Unreliability and instability of labor has an objective character and is a natural manifestation of the emerging economic and social order. The phenomenon of “precarity of employment” appears as a new determinant of the health of employees. The main feature when referring employment and labor relations to the phenomenon of “precarity” is their unreliability.Specifies the terms used: “precariat”; “precarious work”; precompact; the precariat. An essential characteristic of precarious employment is the violation of social and labor rights and lack of job security. A significant indicator of precarity is underemployment. Precarity induces the potential danger of dismissal of the employee and the resulting stress, psychosomatic disorders and pathological processes in the psyche.Precarious employment and related labor relations have become widespread. Many employees are deprived of social guarantees, including those related to labor safety, payment for holidays and temporary disability, and provision of preventive measures. Th is leads to a violation of the state of well-being, as well as the deterioration of individual and public health.

1. Yearly records of worker Vespula germanica (Fabricius) taken in suction traps at Silwood Park (28 years) and at Rothamsted Research (39 years) are examined. 2. Using the autocorrelation function (ACF), a significant negative 1-year lag followed by a lesser non-significant positive 2-year lag was found in all, or parts of, each data set, indicating an underlying population dynamic of a 2-year cycle with a damped waveform. 3. The minimum number of years before the 2-year cycle with damped waveform was shown varied between 17 and 26, or was not found in some data sets. 4. Ecological factors delaying or preventing the occurrence of the 2-year cycle are considered.

Post-operative alveolitis is a topical issue in dental practice, which is also reflected by the etiopathogenic aspects. The conservative principle requires the maintenance of dento-periodontal units in the arch for as long as possible, but there are situations where dental extraction is required. The healing process of the post-surgical wound is complex and involves processes of gingival mucosal regeneration and bone reshaping, involving several local factors: wound size, presence of infection, alveolar vascularization, intraalveolar foreign bodies, and general factors, especially general condition, age and body reactivity. The quality, structure, maintenance, and retraction of the clot are key factors in the formation of connective tissue during the healing of the post-extraction would. At the Oral and Maxillofacial Surgery Clinic of Gala�i, during a 2-year period between January 2015 and December 30, 2016, 2780 patients that required surgery - dental extraction were consulted and diagnosed. We found that among those 2780 patients with dental extractions 105 (3.77%) had post-treatment alveolitis. No post-surgical alveolitis from the case study was complicated by osteomyelitis of the jaws or by suppurations of the superficial or deep compartments of the face. The prophylactic measures in each dental extraction, together with the correct and timely curative treatment, combined with the dentist�s competence and responsibility, can shorten the time of suffering, actively combating the risk factor and accelerating the social reintegration of the patient with post-treatment alveolitis.

The legacy of the social construction of race, class, and gender within the social construction of smartness and identity in US schools are synthesized utilizing meta-ethnography. The study examines ethnographies of smartness and identity while also exploring what meta-ethnography has to offer for qualitative research. The analyses demonstrate that race, class, and gender are key factors in how student identities of ability or smartness are constructed within schools. The meta-ethnography reveals a better understanding of the daily, sociocultural processes in schools that contribute to the denial of competence to students across race, class, and gender. Major themes include epistemologies of schooling, learning as the production of identity, and teacher power in shaping student identities. The results are significant in that new insights are revealed into how gender, class, and racial identities develop within the daily practices of classrooms about notions of ability.

Social behaviour in solitary carnivores has long been an active area of investigation but for many species remains largely founded in conjecture compared to our understanding of sociality in group-living species. The social organization of the wolverine has, until now, received little attention beyond its portrayal as a typical mustelid social system. In this chapter the authors compile observations of social interactions from multiple wolverine field studies, which are integrated into an ecological framework. An ethological model for the wolverine is proposed that reveals an intricate social organization, which is driven by variable resource availability within extremely large territories and supports social behaviour that underpins offspring development.
