Assessing Racial and Ethnic Differences in Attitudes towards the Use of Physical Discipline in Parenting: A Mixed-Methods Approach

Using a concurrent nested mixed-methods approach, this study assessed racial and ethnic differences in attitudes towards the use of physical discipline in parenting based on data recently collected in Nebraska. Relative to Non-Hispanic White parents, African American parents were more likely to approve the practice of physical punishment to correct misbehavior of children, whereas Hispanic parents were less likely to support physical punishment. There was a positive relationship between acculturation and approval of physical discipline among Hispanic parents. Understanding these differences can help inform the design and implementation of future parenting education programs for parents of different racial and ethnic backgrounds.     

School Meals and Food Poverty: Children’s Views,Parents’ Perspectives and the Role of School

This paper addresses the importance of school meals in balancing food budgets and diets among 45 low‐income families in Portugal. Drawing on interviews with both parents and children (aged 11–15 years) we found that children’s views on the quality of school meals affect their willingness to eat at school and heighten parental concerns with health, food and resources. For parents, school meals are crucial to ensure children’s dietary variety and balancing tight food budgets. Schools’ role in food poverty alleviation is also critically addressed, contributing to current and future sociological studies of children, school meals and food poverty.     

Reference database of hematological parameters for growing and aging rats

The normal hematological values in various phases of the rat life provide a valuable guide to researchers and could be useful for experimental works. However, database information available on the literature are incomplete. Aim: This study aimed to present normal hematological parameters of young and aged rats.

Methods: Male and female rats were distributed into seven experimental groups with 1, 2, 3, 6, 12, 18, and 24 months of age. Blood samples taken from the tails were analyzed. Normal hematological values were determined for each age group.

Results: Rats showed a progressive weight gain with advancing age, predominantly after 3 months of life. With advancing age, differences were found on hematological parameters: some of them showed a progressive rise with age and others did not. Hemoglobin levels and hematocrit did not change while the number of circulating red blood cells suffered slight increase.

Conclusion: The present study determined the normal values for absolute and relative hematological parameters in Wistar rats from 2 to 24 months for male and female rats. The results can be used in studies of effects of aging, feeding, and medications on growing and aging rats.     

Prediction of Human Development from Environmental Indicators

The Sustainable Development Goals (SDG) list the objectives and targets that should be addressed to solve the global issues regarding sustainable development. They encompass the social, economic and environmental dimensions and search for solutions that are able not only to monitor but also to control the operational indicators attributed to each objective. It is expected that many of these indicators are associated to each other and the accurate understanding of these correlations allows to build predictive statistical models that can improve the monitoring and controlling of variables. It would increase the rate of success in achieving the SDG. This study tested a linear multivariate model able to predict the human development index based on environmental variables which are related to SDG 3 (health), 4 (education), 8 (sustainable economic growth and decent work) and 15 (protect, restore and promote sustainable use of terrestrial ecosystems). We fitted the models using the Linear Discriminant Analysis and Best Subset Selection applied to a Linear Multivariate Regression. The model predictive ability was assessed by R² and cross-validation (CV). The results showed that exposure to unsafe sanitation, access to drinking water, tree cover loss, unsafe water quality, wastewater treatment level, and household air pollution are excellent predictors of human development index of a population, with R² = 0.94 and 10-fold CV Mean Squared Error equal to 0.0014. This tool can help stakeholders to monitor and control indicators attributed to good health and well-being, quality education, clean water and sanitation, decent work and economic growth, sustainable cities and communities and life on land sustainable development goals.     

The impacts of painful noise in the apprehension of sound references on context of a big band

This study aims to describe the painfulness applied to situations of teaching-learning of a Big Band in a School of Music of a Brazilian Federal University. Moreover, the concept of what painful noise is will be developed, applied to this context. After Ergonomic Work Analysis [2], the following variables were selected to characterize the painful noise: volume, height, frequency, sound confluence and reverberation. To relate the influence of painful noise on modes operatives, were explained the operative strategies used by teacher and students during the performance in group of this Big Band.     

Substrate influence on aromatic plant growth in extensive green roofs in a Mediterranean climate

Green roofs have been described as technical solutions to overcome urban environmental problems, such as decrease of vegetation and stormwater management. In the present study, two pilot 20 m² extensive green roofs were implemented in an urban Mediterranean region, at a 1st storey on a warehouse building structure, in order to test the adequacy of different substrates for supporting aromatic plants (Lavandula dentata, Helichrysum italicum, Satureja montana, Thymus caespititius and Thymus pseudolanuginosus). Experimental substrates included expanded clay and granulated cork as main components, supplemented with organic matter and crushed egg shell. A commercial substrate that obeys to FLL guidelines was also tested. Plant growth was assessed and compared within each platform. All experimental substrates proved to be adequate for vegetation growth, with the combination of 70% expanded clay, 15% organic matter and 15% crushed egg shell showing the best results regarding plant establishment and growth over time. Water runoff quality parameters - turbidity, pH, conductivity, NH₄ ⁺, NO₃ ^?, PO₄ ^3? - met standard values required for water reuse for non-potable purposes, such as toilet flushing or irrigation. Preliminary qualitative thermographic measurements comparing surface temperature of different plant species and the substrate showed that temperature of vegetation surface was lower than substrate, reinforcing green roofs benefits of lowering air temperature in their surroundings. The present research shows that aromatic vegetation combined with clay substrates are suitable for green roofs located in countries of the Mediterranean region.     

Doing Gender in the Conference Hall: Do Men and Women Behave Differently in Engineering Scientific Environments?

The literature on women in STEM areas displays the barriers that women face at scientific workplaces, showing important interaction where they do and undo gender. However, there is a lack of research about the extent men and women do and undo gender in networking environments. This is a participant observation at Human-Computer Interactions annual conferences in a mainly male-dominated environment. It explored how researchers are ‘doing’ and ‘undoing’ gender focusing on two main dimensions: the gender roles adopted by men and women during the presentations and social activities, and the gender contents exposed in their research talks. A first result shows that sex and gender issues are trivialized in research contents by both men and women researchers. A second result reveals that men and women unintentionally and successively ‘do’ and ‘undo’ gender as a strategy to fit into a neutral and accepted identity of engineering and computer scientists.
