Sexual selection is a crucial element to understand behavioral evolution. Teleost fish have been considered as good models for research on sexual selection in the last decades due to their variety of sexual behavior. Female fish can choose males based on body and behavioral traits, such as body size, body color, ornaments, territorial quality, nest size and courtship behavior. Choices are based upon several types of sensorial inputs, such as visual, chemical, sonorous and electrical signals. Intrasexual selection also acts on females because they can mate with a dominant individual in male-male competitions. For both approaches, there is an expectation regarding the benefits of sexual selection by means of female choice. However, in several cases females do not choose the dominant male. In this mini-review, we present and discuss both intersexual and intrasexual mechanisms of sexual selection in fish and point out that females do not always choose a male for mating.

A recent theory suggests that economic considerations are more important than genetic ones in the emergence and maintenance of social behavior. Evolution of social behavior in wasps, thus, could be based on the development of worker castes, which increase the efficiency of brood care and energy use of the colony. If so, social wasps should collect a larger range of prey, favoring polyethism, as social behavior should increase the adaptive value of social species among wasps by increasing the range of prey accessible. We explored the literature and showed that the Eumeninae, which are mostly solitary, draw prey from significantly fewer orders of arthropods than wasps in the subfamily Vespinae and Polistinae, which are mainly social, supporting the hypothesis that social behavior may have emerged as a more efficient way to feed and care for the young by opening a wider range of food sources, increasing the amount of food and quality of care provided to the young. Two alternative explanations of this data are also discussed.

This study aims to conduct an analysis on the social aspects present in the works of the Argentine economist Raúl Prebisch (1901-1986). Based on the author's research on the economic development of the peripheral countries, it will be demonstrated how the social and economic factors have interconnected in the developmental theory of the peripheral worldwide economy. To achieve this goal, the six works of Prebisch considered essentials by Economic Commission for Latin America and the Caribbean (ECLAC) were used as main bibliographic axis. Such texts are: Introduction to Keynes, The Economic Development of Latin America and Its Principal Problems, Economic development or monetary stability: the false dilemma, Towards a Dynamic Development Policy for Latin America, .Change and Development: Latin America's Great Task, Capitalismo periférico: crisis y transformación, Five stages in my thinking on development. Firstly the topics essential to economic development according to the author will be exposed, such as industrialization of peripheral countries as a means of raising the income of masses and the way it should be coordinated beyond the theoretical author's choice on historical events, the evolution of the deterioration of terms of trade between peripheral and central countries and the need for productivity gains to increase the income of the worker. Afterwards it will be exposed how such terms align with social inequalities and which definitions are incorporated by the author on the subject

The aim of the research that originated this article was the analysis of the social trajectory of students from a public preparatory course and the verification of their expectations about higher education. Data collection was based on a questionnaire with open and closed-ended questions and a semi-structured interview, based on the models used by Muzzetti (1997). Data were analyzed by the elaboration of thematic charts. Based on the researches conducted by Pierre Bourdieu (1997, 2007), this research concluded that the students understand that schooling is, besides being a viable alternative in the search for social ascension, the redeeming of social ills. Profession choice based on natural talent or divine gift generate expectations which attest the lack of knowledge about the school system by students and their parents, which is reinforced by the belief in opportunity equality.
