Animal personalities are common across taxa and have important evolutionary and ecological implications. Such consistent individual differences correlate with important life-history traits such as dispersal. Indeed, some environmental conditions are supposed to determine dispersers with a specific personality. For example, an increased density should promote the departure of individuals with less social tolerance. Therefore, we hypothesized that dispersers from high-density populations should primarily be asocial individuals, whereas dispersers from low-density populations should be social individuals. In the common lizard ( Lacerta vivipara ), we measured attraction towards the odour of conspecifics on juveniles at birth as a metric of social tolerance. We then released these juveniles into populations of different densities and measured dispersal and settlement behaviours with regard to social tolerance. One year later, we again measured the social tolerance of surviving individuals. The social tolerance is constant across time and strongly reflects the individual's dispersal and settlement patterns with respect to population density. These results strongly suggest that social personalities exist and influence dispersal decisions. Further studies will help to elucidate the proximate and ultimate determinants of social personalities.

Life-history traits involved in trade-offs are known to vary with environmental conditions. Here, we evaluate the response of the trade-off between ‘offspring number’ versus ‘energy invested per offspring’ to ambient temperature in 11 natural populations of the common lizard, Zootoca vivipara . We provide evidence at both the intra- and interpopulation levels that the trade-off is reduced with an increase in air temperature. If this effect enhances current individual fitness, it may lead to an accelerated pace of life in warmer environments and could ultimately increase adult mortality. In the context of global warming, our results advocate the need for more studies in natural populations to explore interactions between life-history traits' trade-offs and environmental conditions.

AbstractLookism is a term used to describe discrimination based on the physical appearance of a person. We suppose that the social impact of lookism is a philosophical issue, because, from this perspective, attractive people have an advantage over others. The first line of our argumentation involves the issue of lookism as a global ethical and aesthetical phenomenon. A person’s attractiveness has a significant impact on the social and public status of this individual. The common view in society is that it is good to be more attractive and healthier. This concept generates several ethical questions about human aesthetical identity, health, authenticity, and integrity in society. It seems that this unequal treatment causes discrimination, diminishes self-confidence, and lowers the chance of a job or social enforcement for many human beings. Currently, aesthetic improvements are being made through plastic surgery. There is no place on the human body that we cannot improve with plastic surgery or aesthetic medicine. We should not forget that it may result in the problem of elitism, in dividing people into primary and secondary categories. The second line of our argumentation involves a particular case of lookism: Melanie Gaydos. A woman that is considered to be a model with a unique look.

The article provides a philosophical analysis of the tropological theory of the history of H. White. The researcher claims that history is a specific kind of literature, and the historical works is the connection of a certain set of research and narrative operations. The first type of operation answers the question of why the event happened this way and not the other. The second operation is the social description, the narrative of events, the intellectual act of organizing the actual material. According to H. White, this is where the set of ideas and preferences of the researcher begin to work, mainly of a literary and historical nature. Explanations are the main mechanism that becomes the common thread of the narrative. The are implemented through using plot (romantic, satire, comic and tragic) and trope systems – the main stylistic forms of text organization (metaphor, metonymy, synecdoche, irony). The latter decisively influenced for result of the work historians. Historiographical style follows the tropological model, the selection of which is determined by the historian’s individual language practice. When the choice is made, the imagination is ready to create a narrative. Therefore, the historical understanding, according to H. White, can only be tropological. H. White proposes a new methodology for historical research. During the discourse, adequate speech is created to analyze historical phenomena, which the philosopher defines as prefigurative tropological movement. This is how history is revealed through the art of anthropology. Thus, H. White’s tropical history theory offers modern science f meaningful and metatheoretically significant. The structure of concepts on which the classification of historiographical styles can be based and the predictive function of philosophy regarding historical knowledge can be refined.

The results of the study of the duration of the juvenile period of indigenous Chechen willow leaf pear genotypes (Pyrus salicifolia Pall.) are given in connection with the acceleration of the breeding process and the use of selected forms in pear breeding for high precocity. The studies were carried out in 2016-2019 at OOO “Orchards of Chechnya” in accordance with the Agreement on creative cooperation with the Russian Research Institute of Fruit Crop Breeding. The work was carried out in accordance with generally accepted programs and methods. The objects of the study were one-year and two-year-old pear seedlings obtained from sowing seeds of selected dwarf and low-growing local Chechen forms of willow pear (P. salicifolia Pall.), laying fruit buds on annual growths and seedlings of Caucasian pear (P. caucasica Fed.), 20 500 pcs. of each specie. The aim of the research was to study the potential of precocity of willow pear seedlings and to reveal of selected forms with the greatest degree of this trait. Stratified seeds were sown in the sowing department of the OOO “Orchards of Chechnya” production nursery in April, 2017. The seedlings were grown according to the common technology in dryland conditions on the plot with chestnut soil. The first fl owering of plants was noted in the spring, 2019. As a result of the research, for the first time on a large number of the experimental material it was found that in the off spring of the indigenous Chechen willow leaf pear genotypes, the selection of a little more than 2% of seedlings with a very short juvenile period (2 years) was possible. They are of great interest in accelerating the breeding process and in the selection of new pear varieties with high precocity. 20 willow leaf pear genotypes were selected for the further use in breeding for high precocity and as sources of the trait of short juvenile period.

Consumer behavior is a complex phenomenon which is evolving according to the time, situations, demographic characteristics of individuals, personality traits, cultural influences etc. The personality of individuals is a unique dynamic organization of the characteristics of a particular person, physical and psychological, which influence behavior and responses to the social and physical environment. It gives the impression that consumer buying is always influenced by their personality. Therefore, many marketers make use of personality traits in the advertisement of products and at the same time they enhance their marketing strategy. The marketers always designed different products and target specific market segments which commonly addressed on individuals personality traits. The individuals few personality traits influence consumer for impulsive buying behavior. The aim of present research is to study the personality traits influence on consumer impulsive buying behavior as it will help to create opportunities of doing business and dealing with customers. The objectives of this research are: (1) to investigate the influence of personality traits on consumer impulsive buying behavior, and (2) to identify the role of gender and their personality traits influence on consumer impulsive buying behavior. To fulfill the purpose of the study, the researchers randomly collected sample and divided them on the basis of gender, 60 males and 60 females. Data were collected from Delhi and NCR region. The data were analyzed using statistical applications such as correlation and t Test. The result was revealed that the common personality traits have a significant relationship with impulsive buying behavior that is psychoticism in the case of male and female. The role of gender has significant differences in impulsive buying behavior. The man showed more impulsive buying behavior compare to women.

There are two ways to answer the question, What can Catholic social thought learn from the social sciences about the common good? A more modern form of Catholic social thought, which primarily thinks of the common good in terms of the equitable distribution of goods like health, education, and opportunity, could benefit from the extensive literature in public policy, economics, and political science, which study the role of institutions and policies in generating desirable social outcomes. A second approach, rooted in pre-Machiavellian Catholic thought, would expand on this modern notion to include concerns about the way the culture shapes our understanding of what genuine human flourishing entails. On that account, the social sciences offer a valuable description of human life; but because they underestimate how human behavior is shaped by institutions, policies, and the discourse of social science itself, their insights need to be treated with caution.


The present work, The Struggle of My Life: An Autobiography of Swami Sahajanand Saraswati, is an English translation of Sahajanand’s autobiography, written in Hindi, Mera Jeevan Sangarsh. It carries an introduction by the translator which briefly deals with the Swami’s life and legacy. It needs to be emphasized that this is not an autobiography in the common run. Its primary focus is not on Swami’s persona; its central theme is the cause of the freedom movement in general and in particular, of the peasant movement under his leadership. It tells of the life and legacy of one of the most uncompromising and fearless freedom fighters and peasant leaders. It covers the social and political history of one of the most crucial periods of our national life, 1920–47. Today, when the Indian peasantry is faced with a number of intractable problems, it reminds them of the struggles of the peasants of yesteryears and the kind of trials and tribulations they went through. It is also remarkable that despite his vast learning and command over Sanskrit, Swami chose to write in simple, colloquial Hindi. That only speaks for his total identification with the masses. Both the teaching and student community as well as general readers would find this book useful, interesting and intellectually stimulating.

This chapter explores the funerary rites in the Phoenician-Punic world from a comprehensive point of view, and it focuses on the common points arising from a large amount of data. The concern for burying their deceased and the belief in the soul’s afterlife show that the Phoenicians considered death as a transformation rather than as the end of a person’s life. Through our access to archaeological remains and written sources, we can reconstruct the existence of a meaningful burial program that was destined to provide a “good death” and afterlife. Funerary rituals, thus, are the actions or gestures to achieve this goal. The aim of this chapter is to explain the rites that family members undertook once someone died, in order to transform correctly the deceased person into an otherworldly being, the ancestor. The social implications of the data arising from burials are also briefly considered.
