Evolutionary algorithms have been widely used for Artificial Neural Networks (ANN) training, being the idea to update the neurons' weights using social dynamics of living organisms in order to decrease the classification error. In this paper, we have introduced Social-Spider Optimization to improve the training phase of ANN with Multilayer perceptrons, and we validated the proposed approach in the context of Parkinson's Disease recognition. The experimental section has been carried out against with five other well-known meta-heuristics techniques, and it has shown SSO can be a suitable approach for ANN-MLP training step.

According to data from the World Health Organization, the older population will grow sixteenfold from 1950 to 2025 in comparison to a fivefold population growth in the same period, which is referred to by UNO as the “Ageing Era”. This places Brazil in the sixth position in the contingent of older individuals worldwide, with a number that is higher than 32 million. Considering how topics such as quality of life and social vulnerability are important in face of the growing older population, these topics must be furthered studied so that they can be understood as important variables for both better clinical practice and scientific research. To describe the social vulnerability and evaluate the quality of life of older individuals in a population hospitalized in the internal medicine ward of Bauru State Hospital. This is a descriptive qualitative study that was conducted by means of interviews and using Bardin’s discourse analysis. The inclusion criteria used in this study were: individuals at 60 years of age who were mentally capable of answering the proposed questions. Two categories concerning Quality of Life and Social Vulnerability emerged from the interviews. The following emerged from the theme Quality of Life: “Life as something important” and subcategories that involved feeling useful in society, having a supportive family, independence, optimism and joy and survival. Also, the following emerged from the theme Social Vulnerability: “Negative recognition of older individuals in society” and subcategories that involved lack of respect, functional disability, family indifference, housing-related insecurity, an inefficient health care system and loneliness. Quality of Life and Social Vulnerability are largely discussed themes in the present scenario. In this study, it was possible to perceive that the older population needs social support, effective public... (Complete abstract click electronic access below)

There is a growing recognition among wildlife managers that focusing management on wildlife often provides a temporary fix to human–wildlife conflicts, whereas changing human behavior can provide long-term solutions. Human dimensions research of wildlife conflicts frequently focuses on stakeholders’ characteristics, problem identification, and acceptability of management, and less frequently on human behavior and evaluation of management actions to change that behavior. Consequently, little information exists to assess overall success of management. We draw on our experience studying human–bear conflicts, and argue for more human dimensions studies that focus on change in human behavior to measure management success. We call for help from social scientists to conduct applied experiments utilizing two methods, direct observation and self-reported data, to measure change in behavior. We are optimistic these approaches will help fill the managers’ tool box and lead to better integration of human dimensions into human–wildlife conflict management.

Nestmate recognition is fundamental for the maintenance of social organization in insect nests. It is becoming well recognized that cuticle hydrocarbons mediate the recognition process, although the origin of recognition cues in stingless bees remains poorly explored. The present study investigates the effects of endogenously-produced and environmentally-acquired components in cuticular hydrocarbons in stingless bees. The tests are conducted using colonies of Plebeia droryana Friese and Plebeia remota Holmberg. Recognition tests are performed with four different groups: conspecific nestmates, conspecific non-nestmates, heterospecifics and conspecific, genetically-related individuals that emerge in a heterospecific nest. This last group is produced by introducing brood cells of P. droryana into a P. remota colony, and the resulting adult bees are tested for acceptance 10 days after emergence. For all groups, 15 individuals are sampled for chemical analysis. The results show the acceptance of all conspecific nestmates, and the rejection of almost every conspecific non-nestmate and every heterospecific bee. Genetically-related individuals emerging from heterospecific nests present intermediate rejection (66.7% rejection). Chemical analysis shows that P. droryana individuals emerging in a P. remota nest have small amounts of alkene and diene isomers found in P. remota cuticle that are not found in workers from the natal nest. The data clearly show that the majority of the compounds present in P. droryana cuticle are endogenously produced, although a few unsaturated compounds are acquired from the environment, increasing the chemical differences and, consequently, the rejection percentages.
