New stage-discharge relationship for cylindrical and semi-cylindrical edged sluice gates

2019

Abstract Gates are simple hydraulic structures which have been widely used for flow control and measurement in irrigation networks. In this paper new sluice gates with cylindrical and semi-cylindrical edges were introduced and the flow movement below these types of gates was experimentally investigated for both free- and submerged-flow conditions. The Buckingham theorem of dimensional analysis and the self-similarity theory were applied for developing the stage-discharge relationships for the two investigated flow conditions. For these cylindrical and semi-cylindrical edged gates and a free-flow condition, the proposed stage-discharge relationship was characterized by an estimate error less…

Taxonomy of homicides of women in intimate partner relationships

2018

Intimate partner violence prevention is a challenge that has received wide international interest. Homicide is the most serious result of this type of violence, although its prevalence is low and its etiology is complex. This paper briefly reviews the description of the problem from a gender perspective and the existence of asymmetry, the perspective of violence and its description of differential risk factors, and the ecological model that connects personal, contextual, and societal variables, presenting a more integrative proposal. Studies analyzing and comparing homicide profiles are described, as well as the state of the art regarding risk assessment, with special attention to the impli…

Stress conceptions in life event research: Towards a person‐centred perspective

1987

The present article focuses on a discussion of the theoretical foundations of life event research. Since critical life events are usually regarded as stressful events, the main question is which concepts of stress are employed in different life event approaches and what is their rationale. The discussion centres on two topics that have to be treated independently: the question of specificity vs nonspecificity and the question of individualized vs normative weightings. It is shown that different life event approaches rely on different concepts of stress. Numerous objections lead to a rejection of the nonspecificity concept and a normative proceeding. However, even when a specificity view of…

Cyberbullying, psychosocial adjustment and suicide ideation in adolescence

Romantic relationships in intra-ethnic and inter-ethnic adolescent couples in Germany: The role of attachment to parents, self-esteem, and conflict r…

2010

We investigated romantic relationships in a sample of 380 adolescents who formed 190 heterosexual couples (mean age: females 17 years; males 18 years): 173 intra-ethnic (German) couples and 17 inter-ethnic couples. Factor analyses revealed two types of love experiences: (a) experiences of attraction and a passionate focus on the partner (passionate love) and (b) experiences of affiliation (companionate love). No differences were found between intra-ethnic and inter-ethnic couples in romantic experiences, self-esteem, and conflict resolution skills. Adolescents in intra-ethnic couples had more close relations with parents than adolescents in inter-ethnic couples. Actor—Partner Interdependen…

Public Attitudes Toward Reporting Partner Violence Against Women and Reporting Behavior

2006

Drawing from attitude-behavior research tradition, this study used a national probabilistic sample of the Spanish adult population (N= 2,432) to test hypotheses regarding correlates of public attitudes toward reporting partner violence against women, and the relationship between attitudes toward reporting and actual reporting behavior. Results show the importance of several correlates of public attitudes toward reporting. Also, our results have suggested a potential disconnect between attitudes and behavior because failure to intervene appears to be a common response of those aware of incidents of partner violence against women.

Factores desencadenantes del perjuicio de los simúlidos

2021

El incremento de los daños causados por los dípteros simúlidos, desde finales de la década de los 90, ha suscitado un interés especial en el estudio de este grupo de dípteros en nuestro país. Además de la importancia de los estudios faunísticos, para conocer las especies presentes en nuestros hábitats, resulta de interés conocer otros aspectos ligados a la incidencia de sus ataques tanto al ser humano como a las especies animales de interés veterinario. La revisión del estado actual de la familia Simuliidae en España ha permitido la confección del listado de las 52 especies presentes y sus mapas de distribución. Se han llevado a cabo estudios de eficacia de tratamientos biol…

Making sense of domestic violence intervention in professional health care

2011

Intervening in domestic violence in the health care and social service settings is a complex and contested issue. In this qualitative, multidisciplinary study, the barriers to but also the possibilities for health care professionals in encountering victims of violence were scrutinised. The focus was on omissions in service structure and practices. The data consisted of six focus group interviews with nurses, physicians, social workers and psychologists in specialist health care (n = 30) conducted in Finland in 2009. The aim was to explore professionals' processes of making sense of violence interventions and the organisational practices of violence interventions. Four types of framing of th…

Maternal Affection Moderates the Associations Between Parenting Stress and Early Adolescents’ Externalizing and Internalizing Behavior

2019

The present study investigated the role of parenting stress in early adolescents’ externalizing and internalizing behavior and, particularly, the moderating effect of maternal affection on these associations. The data of 992 early adolescents ([Formula: see text]; 454 girls) and their mothers during the transition from primary school to lower secondary school were analyzed. The results showed that when maternal affection was low, parenting stress was not related to the changes in early adolescents’ externalizing or internalizing behavior. In contrast, when maternal affection was high, low parenting stress related to a decrease and high parenting stress to an increase in such behavior. The …
