Determinants of the exclusive breastfeeding abandonment in children assisted by interdisciplinary program on breast feeding promotion.

Objective: To identify variables potentially related with the exclusive breastfeeding abandonment in children assisted by interdisciplinary program on breast feeding promotion. Methods: Data were collected by a longitudinal study with 111 mothers who breastfeed their children until six months of age. Univariate analyses were used to assess factors associated with the exclusive breastfeeding abandonment, and also multiple regression analyses. Results: The mothers were divided in two groups: 57 mothers breastfeed, exclusively, their children until six months of age and 54 mothers introduced other kinds of food before this age. The following variables were found to be factors associated with the exclusive breastfeeding abandonment: pacifier use (OR 4,65; IC95% 1,66-12,99), social and economic high level (OR 11,46; IC95% 3,09-42,37) and mother's work (OR 2,44; IC95% 0,91-5,62). Conclusion: Pacifier use, social and economic high level and mother's work are associated with the exclusive breastfeeding abandonment.16104139414

A survey of cognitive assistants

Cognitive Assistants is a subset area of Personal Assistants focused on ubiquitous and pervasive platforms and services. They are aimed at elderly people’s needs, habits, and emotions by being dynamic, adaptive, sensitive, and responsive. These advances make cognitive assistants a true candidate of being used in real scenarios and help elderly people at home and outside environments. This survey will discuss the cognitive assistants’ emergence in order to provide a list of new projects being developed on this area. We summarize and enumerate the state-of-the-art projects. Moreover, we discuss how technology support the elderly affected by physical or mental disabilities or chronic diseases.Programa Operacional Temático Factores de Competitividade (UID/CEC/00319/2013

What do γ\gamma-ray bursts look like?

There have been great and rapid progresses in the field of $\gamma$-ray bursts (denoted as GRBs) since BeppoSAX and other telescopes discovered their afterglows in 1997. Here, we will first give a brief review on the observational facts of GRBs and direct understanding from these facts, which lead to the standard fireball model. The dynamical evolution of the fireball is discussed, especially a generic model is proposed to describe the whole dynamical evolution of GRB remnant from highly radiative to adiabatic, and from ultra-relativistic to non-relativistic phase. Then, Various deviations from the standard model are discussed to give new information about GRBs and their environment. In order to relax the energy crisis, the beaming effects and their possible observational evidences are also discussed in GRB's radiations.Comment: 10 pages, Latex.

A Human Development Framework for CO2 Reductions

Although developing countries are called to participate in CO2 emission reduction efforts to avoid dangerous climate change, the implications of proposed reduction schemes in human development standards of developing countries remain a matter of debate. We show the existence of a positive and time-dependent correlation between the Human Development Index (HDI) and per capita CO2 emissions from fossil fuel combustion. Employing this empirical relation, extrapolating the HDI, and using three population scenarios, the cumulative CO2 emissions necessary for developing countries to achieve particular HDI thresholds are assessed following a Development As Usual approach (DAU). If current demographic and development trends are maintained, we estimate that by 2050 around 85% of the world's population will live in countries with high HDI (above 0.8). In particular, 300Gt of cumulative CO2 emissions between 2000 and 2050 are estimated to be necessary for the development of 104 developing countries in the year 2000. This value represents between 20% to 30% of previously calculated CO2 budgets limiting global warming to 2{\deg}C. These constraints and results are incorporated into a CO2 reduction framework involving four domains of climate action for individual countries. The framework reserves a fair emission path for developing countries to proceed with their development by indexing country-dependent reduction rates proportional to the HDI in order to preserve the 2{\deg}C target after a particular development threshold is reached. Under this approach, global cumulative emissions by 2050 are estimated to range from 850 up to 1100Gt of CO2. These values are within the uncertainty range of emissions to limit global temperatures to 2{\deg}C.Comment: 14 pages, 7 figures, 1 tabl

Posterior Spiracles of Fourth Instar Larvae of Four Species of Phlebotomine Sand Flies (Diptera: Psychodidae) under Scanning Electron Microscopy

In the present study, posterior spiracles of laboratory-reared fourth instar larvae of Lutzomyia longipalpis, L. migonei, L. lenti, and L. whitmani (Diptera: Psychodidae) of the State of Ceará, Brazil, were examined under scanning electron microscopy. The number of papillae of spiracles examined varied according to the species examined, but no intraspecific differences were found. The importance of this structure to sand fly larva identification and phylogeny is commented

Relationship between craving and personality in treatment-seeking women with substance-related disorders

BACKGROUND: Individual differences may impact susceptibility to addiction. The impact of personality features on drug craving, however, has not been studied, particularly in women. METHODS: Ninety-five treatment-seeking women with substance dependence, abstinent for at least 5 and no more than 21 days, were investigated regarding the correlation between personality factors and craving. Personality was assessed using the Temperament and Character Inventory (TCI), the NEO Personality Inventory Revised (NEO-PI-R), and the Barratt Impulsiveness Scale version 11 (BIS-11). Cravings were assessed through the Pennsylvania Craving Scale (PCS), and the Craving Questionnaire (CQ). Anxiety and depressive symptomatology were also recorded. RESULTS: Craving scores were positively correlated with depression and negatively correlated with number of days abstinent from substance use. Also, craving scores were positively associated with the novelty-seeking factor from the TCI and the total score on the BIS-11, and negatively associated with the conscientiousness and agreeableness facets of the NEO-PI-R. CONCLUSION: Findings suggest that personality features, particularly impulsiveness, can be important predictors of craving in women, which has important implications for treatment planning

Human behaviour and economic growth: a psychocultural perspective on local and regional development

A renewed emphasis on behavioural traits has emerged as a means of explaining regional and local differences in economic performance and development. Given this, the aim of this study is to identify distinct local psychocultural behavioural profiles and to examine the extent to which these are associated with economic growth. Combining theories of community culture and personality psychology into a holistic spatially-oriented perspective, the paper argues that the types of human behaviour found across local places emerges from the co-evolution of cultural and personality factors. An empirical analysis of localities in Great Britain identifies and explores three underlying psychocultural profiles: Diverse Extraversion; Inclusive Amenability and Individual Commitment. It is found that inclusive amenable and individually committed psychocultural behaviour generally appear to hold back local economic growth, with the exception of recessionary periods. The reverse relationship is somewhat the case for diverse extravert behaviour. It is concluded that a better understanding of the holistic relationship and co-evolution of the cultural and psychological behavioural make-up of localities and regions has the potential to provide new insights into expected development outcomes as well as the forms of policy intervention that are required within regions and localities, each of which has its own individual psychocultural character
