Distributed-memory parallelization of an explicit time-domain volume integral equation solver on Blue Gene/P

Two distributed-memory schemes for efficiently parallelizing the explicit marching-on in-time based solution of the time domain volume integral equation on the IBM Blue Gene/P platform are presented. In the first scheme, each processor stores the time history of all source fields and only the computationally dominant step of the tested field computations is distributed among processors. This scheme requires all-to-all global communications to update the time history of the source fields from the tested fields. In the second scheme, the source fields as well as all steps of the tested field computations are distributed among processors. This scheme requires sequential global communications to update the time history of the distributed source fields from the tested fields. Numerical results demonstrate that both schemes scale well on the IBM Blue Gene/P platform and the memory efficient second scheme allows for the characterization of transient wave interactions on composite structures discretized using three million spatial elements without an acceleration algorithm

Developmental and gender trends in emotional literacy and interpersonal competence among Japanese children

This study explored cross-sectional gender and grade level trends in emotional literacy and interpersonal competence among 913 elementary and middle school students in Japan. Students were presented with two hypothetical scenarios involving mixed emotions and potential interpersonal dilemmas. Results indicated that older children possess greater emotional literacy when compared to younger children. Additionally, girls identified a greater number of emotions, were better able to identify mixed emotions, and were more likely to identify empathic interpersonal behaviours. These gender and grade level considerations may be incorporated into social-emotional learning curricula to enhance the utility and effectiveness of programs for diverse populations.peer-reviewe

Phases of Cost Cutting: Downsizing is Dead; Long Live the Downsizing Phenomenon

This downsizing research article presents a phase typology of job cutting which includes three distinct phases and three levels of argument. Conceptually, the paper draws heavily upon the seminal work of Littler and Gandolfi (2008) seeking to expand and update their 2008 Academy of Management (AOM) Conference paper. The paper culminates with a contemporary discussion of current downsizing practices showcasing that the strategy of downsizing has remained a popular restructuring method on a global scale.downsizing; cost cutting; phase; strategy.

Depression in patients with Type 2 Diabetes in Maltese primary care

Background: Type 2 diabetes and depression are two common chronic conditions affecting the Maltese population with significant and costly effects on health. Multiple studies have demonstrated a higher prevalence of depression in diabetic patients and a link with uncontrolled diabetes; however, despite this, depression is still not considered as important to chronic conditions in terms of the effects it has on health. -- Objectives: This study was conducted to estimate the prevalence of depression in type 2 diabetic patients in primary care and to study their associated risk factors. -- Method: A quantitative, cross-sectional, retrospective, descriptive study was performed among 400 participants with type 2 diabetes attending diabetes clinics within the public health centres in Malta. Patients completed a self-administered questionnaire to quantify depressive symptoms and to study patient and disease characteristics. Convenience sampling was used to collect the data. -- Results: Data analysis showed that the prevalence of depression is around 29.7% among type 2 diabetic patients. Younger diabetics, women, lower educational levels, unemployment, obesity, a family history of depression and uncontrolled diabetes were found to be associated with a higher risk of developing depressive symptoms. -- Conclusions: Screening for depression in type 2 diabetic patients is important due to the high prevalence and significant impact on health. Appropriate management can significantly improve the outcome of both conditions and consequently improve both health and quality of life.peer-reviewe

Personal and family correlates to happiness amongst Italian children and pre-adolescents

This study examines how family functioning, the parent-child relationship and personal factors are related to happiness in 1549 children aged 7 to 14 years old (53% females) in Italy. Children and pre-adolescents completed a set of questionnaires on self-rated happiness, self-concept and loneliness. At least one of their parents filled in questionnaires on family functioning, attachment and their child’s happiness level. No gender differences were found in the direct measure of happiness, but younger participants were happier than older participants, according to both the children’s and parents’ evaluations. Happiness is influenced by positive self-concept, self-esteem and low levels of satisfaction but family functioning does not seem to play a major role. The clinical and social implications of the study are discussed.peer-reviewe

Physiological responses of reared sea bream (Sparus aurata Linnaeus, 1758) to an Amyloodinium ocellatum outbreak

Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves that live within its ecological range. Fish mortalities are usually attributed to anoxia, associated with serious gill hyperplasia, inflammation, haemorrhage and necrosis in heavy infestations; or with osmoregulatory impairment and secondary microbial infections due to severe epithelial damage in mild infestation. However, physiological information about the host responses to A.ocellatum infestation is scarce. In this work, we analysed the proteome of gilthead sea bream (Sparus aurata) plasma and relate it with haematological and immunological indicators, in order to enlighten the different physiological responses when exposed to an A.ocellatum outbreak. Using 2D-DIGE, immunological and haematological analysis and in response to the A.ocellatum contamination we have identified several proteins associated with acute-phase response, inflammation, lipid transport, homoeostasis, and osmoregulation, wound healing, neoplasia and iron transport. Overall, this preliminary study revealed that amyloodiniosis affects some fish functional pathways as revealed by the changes in the plasma proteome of S. aurata, and that the innate immunological system is not activated in the presence of the parasite.DIVERSIAQUA, Portugal [MAR2020]Fundacao para a Ciencia e Tecnologia [SFRH/BD/118601/2016]info:eu-repo/semantics/publishedVersio
