Age-Dependent Fragility and Life-Cycle Cost Analysis of Timber and Steel Distribution Poles Subjected to Hurricanes

Power distribution systems are susceptible to extreme damage from natural hazards especially hurricanes. Hurricane winds can knock down distribution poles thereby causing damage to the system and power outages which can result in millions of dollars in lost revenue and restoration costs. Timber has been the dominant material used to support overhead lines in distribution systems. Recently however, utility companies have been searching for a cost-effective alternative to timber poles due to environmental concerns, durability, high cost of maintenance and need for improved aesthetics. Steel has emerged as a viable alternative to timber due to its advantages such as relatively lower maintenance cost, light weight, consistent performance, and invulnerability to wood-pecker attacks. Both timber and steel poles are prone to deterioration over time due to decay in the timber and corrosion of the steel. This research proposes a framework for conducting fragility analysis of timber and steel poles subjected to hurricane winds considering deterioration of the poles over time. Monte Carlo simulation was used to develop the fragility curves considering uncertainties in strength, geometry and wind loads. A framework for life-cycle cost analysis is also proposed to compare the steel and timber poles. The results show that steel poles can have superior reliability and lower life-cycle cost compared to timber poles, which makes them suitable substitutes.

Applying systems theory to the evaluation of a whole school approach to violence prevention

Issue addressed: Our Watch led a complex 12-month evaluation of a whole school approach to Respectful Relationships Education (RRE) implemented in 19 schools. RRE is an emerging field aimed at preventing gender-based violence. This paper will illustrate how from an implementation science perspective, the evaluation was a critical element in the change process at both a school and policy level. Methods: Using several conceptual approaches from systems science, the evaluation sought to examine how the multiple systems layers – student, teacher, school, community and government – interacted and influenced each other. A distinguishing feature of the evaluation included ‘feedback loops’; that is, evaluation data was provided to participants as it became available. Evaluation tools included a combination of standardised surveys (with pre- and post-intervention data provided to schools via individualised reports), reflection tools, regular reflection interviews and summative focus groups. Results: Data was shared during implementation with project staff, department staff and schools to support continuous improvement at these multiple systems levels. In complex settings, implementation can vary according to context; and the impact of evaluation processes, tools and findings differed across the schools. Interviews and focus groups conducted at the end of the project illustrated which of these methods were instrumental in motivating change and engaging stakeholders at both a school and departmental level and why. Conclusion: The evaluation methods were a critical component of the pilot’s approach, helping to shape implementation through data feedback loops and reflective practice for ongoing, responsive and continuous improvement. Future health promotion research on complex interventions needs to examine how the evaluation itself is influencing implementation. So what? The pilot has demonstrated that the evaluation, including feedback loops to inform project activity, were an asset to implementation. This has implications for other health promotion activities, where evaluation tools could be utilised to enhance, rather than simply measure, an intervention. The findings are relevant to a range of health promotion research activities because they demonstrate the importance of meta-evaluation techniques that seek to understand how the evaluation itself was influencing implementation and outcomes.

Evaluation of water use, yield and water productivity of a high-density orchard (cv. Cobrançosa) subjected to different irrigation regimes – An account of four years

The impact of different irrigation scheduling regimes on the water use, yield and water productivity from a high-density olive grove cv. Cobrançosa in southern Portugal was assessed during the irrigation seasons of 2011, 2012, 2013 and 2014. The experiments were conducted in a commercial olive orchard at the Herdade Álamo de Cima, near Évora (38o 29' 49.44'' N, 7o 45' 8.83'' W; alt. 75 m) in southern Alentejo, Portugal. The orchard was established with 10-year old Cobrançosa trees in grids of 8.0 x 4.2 m (300 trees ha-1) in the E-W direction, and experiments conducted on a shallow sandy loam Regosoil Haplic soil. From mid-May to the end of September the orchard was irrigated and three plots were subjected to one of two irrigation treatments: a control treatment A, irrigated to replace 100% ETc, a moderate deficit irrigation treatment B irrigated to 70% of ETc, and a more severe deficit irrigation treatment C that provided for approximately 50% of ETc. Daily tree transpiration rates were obtained by continuously monitoring of sap flow in representative trees per treatment. Among the irrigated treatments, water use efficiency (WUE, ratio of water used to irrigation- water applied) of treatment C was the highest, with a value of 0.89, being treatment B slightly lower, with a WUE of 0.76. Olive harvest for 2012 was an exceptional “on year”. Bearing yields showed contrasting differences within years where an “on year” was followed by an “off year”. In 2011 and 2012 treatment B yields were 41 and 50% higher than treatment C, respectively. In 2013 treatment B yield was 45% higher than yield of the fully irrigated treatment A, and treatment C showed practically the same yield than treatment A. In the “on year” of 2014 treatment B averaged 48% higher yield than treatment C. Treatment B farm irrigation water productivity (WPI-Farm, ratio of yield to water applied) was the highest among all treatments. Treatment A showed the lowest conversion efficiency of all treatments, indicating treatment B as the adequate deficit irrigation treatment for our Cobrançosa orchard

The Representation of the Female Body in the Multimedia Works of Regina José Galindo

The female body is central to the performance art, poetry and blog site interventions of Guatemalan Regina José Galindo. While Galindo is best known for her performance work, this article compares the hereto overlooked, distinctive and often shocking representations of the female body across her multimedia outputs. We first consider the ways in which, in all three media, Galindo presents an ‘excessive’, carnivalised, grotesque and abject female body. Second, we analyse representations of the female body that has been subjected to violence at a private and public level. In so doing, we show how Galindo not only contests hegemonic visions of gender and (national) identity but also challenges the viewer/reader to engage with, rather than look away from, the violence to which women are subjected in patriarchal society.

Anatomías contrariadas: la representación del cuerpo en la literatura sobre los Andes (Estudios)

La autora analiza tres textos latinoamericanos que muestran construcciones del imaginario andino, extendidas a ciertos estereotipos sobre la corporalidad andina: frágil, dolorida, para la cual la esperanza de liberación radica en un azar. En «Boletín y Elegía de las Mitas», César Dávila presenta una versión del cuerpo indio «exclusivamente centrada en la vejación de lo anatómico» (de su cabeza y genitales, de órganos tan profundos como el corazón y el esqueleto), con lo que el cuerpo desnudo y forzado se convierte en ajeno. En «El sueño del Pongo», de José María Arguedas, el cuerpo del indio oprimido es diminuto, y porta una «gestualidad comprimida que se pone en juego a partir de posturas humilladas». Pese al final aparentemente optimista de ambos textos, se trata de productos culturales que cumplen un rol en el ejercicio de control social. En «Barraquera», de José de la Cuadra, el cuerpo de esta mujer es fundado a partir de violaciones, muertes y migraciones forzadas: habituado a sufrir y callar, para este cuerpo el dolor se convierte en la única vía posible de acceso al placer. Se remarca que el tiempo cronológico de los tres relatos es el de la espera, el tiempo del destino. Para estos cuerpos-lugares siempre vulnerables y violentados, burlados o invisibilizados, lo fatal fundamentaría un cierre de lo histórico.

Definitioner av våld i överlevandes berättelser efter kriget i Bosnien

Definitions of violence in stories of survivors from the Bosnian war Previous research on violence during the war in Bosnia and Herzegovina presents a one-sided picture of the phenomenon ”war violence.” Researchers have emphasized the importance of narratives but they have not focused on stories about war violence, nor have they analyzed the stories of war violence being a product of interpersonal interaction. This article tries to fill this knowledge gap by analyzing the narratives told by survivors of the war in northwestern Bosnia in the 1990s. The aim is to analyze how the survivors describe violence during the war, and also to analyze those discursive patterns that contribute in constructing the category ”war violence.” The construction of the category ”war violence” is made visible in the empirical material when the interviewees talk about (1) a new social order in the society, (2) human suffering, (3) sexual violence, and (4) human slaughter. All interviewees define war violence as morally reprehensible. In narratives on the phenomena ”war violence” a picture emerges which shows a disruption of the social order existing in the pre-war society. The violence practiced during the war is portrayed as organized and ritualized and this creates a picture that the violence practice became a norm in the society, rather than the exception. Narratives retelling violent situations, perpetrators of violence and subjected to violence do not only exist as a mental construction. The stories live their lives after the war, and thus have real consequences for individuals and society.

From domestic violence to sustainable employment

International research has found that domestic violence is a significant barrier to accessing and sustaining work (Lloyd and Taluc 1999, 385; Browne et al. 1999, 398). In the Australian context, the Bureau of Crime Statistics and Research reports that between 6 and 9 per cent of Australian women aged 18 and over are physically assaulted each year and that more than half of all women in Australia experience sexual or physical violence across their adult lifetime. Such behaviour has been estimated to cost $8.1 billion, of which $4.4 billion is estimated to be borne by the victims themselves, $1.2 billion by the general community and smaller amounts by friends and family and various levels of government (Access Economics 2004). This assessment underestimates the costs of domestic violence in terms of the inability of those who have experienced domestic violence to move into and secure sustainable employment options. Despite these statistics there is a dearth of Australian research focussing on the link between domestic violence and its impact on long-term sustainable employment for those who have been subjected to such violence. This paper explores the issue of domestic violence and access to work opportunities. In so doing, it links the work of Gianakos (1999) and her Career Development theory with that of Bandura‘s (1989) Social Cognitive Career Theory to develop a framework which would provide a pathway to enable those who have suffered domestic violence to achieve sustainable employment and economic independence.

Violence against the adolescents of Kolkata: A study in relation to the socio-economic background and mental health

This study attempts to understand the nature of violence suffered by the adolescents of Kolkata (erstwhile Calcutta) and to identify its relation with their socio-economic background and mental health variables such as anxiety, adjustment, and self-concept. It is a cross-sectional study covering a total of 370 adolescents (182 boys and 188 girls) from six higher secondary schools in Kolkata. The data was gathered by way of a semi-structured questionnaire and three standard psychological tests. Findings revealed that 52.4%, 25.1%, and 12.7% adolescents suffered psychological, physical, and sexual violence in the last year. Older adolescents (aged 17–18 years) suffered more psychological violence than the younger ones (15–16 years) (p < 0.05). Sixty nine (18.6%) adolescent students stood witness to violence between adult members in the family. More than three-fifth (61.9%) adolescents experienced at least one type of violence, while one-third (32.7%) experienced physical or sexual violence or both. Whatever its nature is, violence leaves a scar on the mental health of the victims. Those who have been through regular psychological violence reported high anxiety, emotional adjustment problem, and low self-concept. Sexual abuse left a damaging effect on self-concept (p < 0.05), while psychological violence or the witnessing of violence prompted high anxiety scores (p < 0.05), poor emotional adjustment (p < 0.05), and low self-concept (p < 0.05). This study stresses the need to provide individual counselling services to the maltreated adolescents of Kolkata so that their psychological traumas can heal and that they can move on in life with new hopes and dreams.

Effects of an emotional intelligence program in variables related to the prevention of violence

In recent decades, numerous studies have shown a significant increase in violence during childhood and adolescence. These data suggest the importance of implementing programs to prevent and reduce violent behavior. The study aimed to design a program of emotional intelligence (El) for adolescents and to assess its effects on variables related to violence prevention. The possible differential effect of the program on both genders was also examined. The sample comprised 148 adolescents aged from 13 to 16 years. The study used an experimental design with repeated pretest-posttest measures and control groups. To measure the variables, four assessment instruments were administered before and after the program, as well as in the follow-up phase (1 year after the conclusion of the intervention). The program consisted of 20 one-hour sessions. The pretest-posttest ANCOVAs showed that the program significantly increased: (1) El (attention, clarity, emotional repair); (2) assertive cognitive social interaction strategies; (3) internal control of anger; and (4) the cognitive ability to analyze negative feelings. In the follow-up phase, the positive effects of the intervention were generally maintained and, moreover, the use of aggressive strategies as an interpersonal conflict-resolution technique was significantly reduced. Regarding the effect of the program on both genders, the change was very similar, but the boys increased assertive social interaction strategies, attention, and emotional clarity significantly more than the girls. The importance of implementing programs to promote socio-emotional development and prevent violence is discussed.

Psychological interventions for children and young people affected by armed conflict or political violence: a systematic literature review.

Youths exposed to armed conflict have a higher prevalence of mental health and psychosocial difficulties. Diverse interventions exist that aim to ameliorate the effect of armed conflict on the psychological and psychosocial wellbeing of conflict affected youths. However, the evidence base for the effectiveness of these interventions is limited. Using standard review methodology, this review aims to address the effectiveness of psychological interventions employed among this population. The search was performed across four databases and grey literature. Article quality was assessed using the Downs and Black Quality Checklist (1998). Where possible, studies were subjected to meta-analyses. The remaining studies were included in a narrative synthesis. Eight studies concerned non clinical populations, while nine concerned clinical populations. Review findings conclude that Group Trauma Focused-Cognitive Behavioural Therapy is effective for reducing symptoms of posttraumatic stress disorder, anxiety, depression and improving prosocial behaviour among clinical cohorts. The evidence does not suggest that interventions aimed at non clinical groups within this population are effective. Despite high quality studies, further robust trials are required to strengthen the evidence base, as a lack of replication has resulted in a limited evidence base to inform practice.

Killing animals: sociology, species relations and institutionalized violence

Influential voices have argued for a sociology which acknowledges the way we are co-constituted with a range of non-human species as part of the condition of life on this planet. Despite this, sociology has generally retained a conception of the social that is centred on the human. This paper argues for the inclusion of non-human animals in sociological agendas, focusing on the emerging field of the sociology of violence. It examines the institutions and processes through which non-human animals are subjected to different forms of violence, most notably, mass killing.The practice of killing animals is routine,normative,institutionalized and globalized.The scale of killing is historically unprecedented and the numbers killed are enormous. The paper argues that this killing of non-humans raises questions around inequal- ities and intersectionality, human relations with other species, the embedding of violence in everyday practices and links between micro and macro analyses. These are questions with which the new sociology of violence might engage.

Is domestic violence learned? The contribution of five forms of child maltreatment to men's violence and adjustment

On the basis of a learning-theory approach to the intergenerational transmission of violence, researchers have focused almost exclusively on violent men's childhood experiences of physical abuse and witnessing family violence. Little consideration has been given to the coexistence of other forms of child maltreatment or the role of family dysfunction in contributing to violence. This study shows the relationships between the level of child maltreatment (physical abuse, psychological maltreatment, sexual abuse, neglect, and witnessing family violence), childhood family characteristics, current alcohol abuse, trauma symptomatology, and the level of physical and psychological spouse abuse perpetrated by 36 men with a history of perpetrating domestic violence who had attended counseling. As hypothesized, a high degree of overlap between risk factors was found. Child maltreatment, low family cohesion and adaptability, and alcohol abuse was significantly associated with frequency of physical spouse abuse and trauma symptomatology scores, but not psychological spouse abuse. Rather than physical abuse or witnessing family violence, childhood neglect uniquely predicted the level of physical spouse abuse. Witnessing family violence (but not physical abuse) was found to have a unique association with psychological spouse abuse and trauma symptomatology. These results present a challenge to the understanding of domestic violence obtained from learning theory.
