Accident avoidance importance for building demolition

Building demolition, as compared to building construction is always carried out as quickly and cheaply as possible. The nature of limited time and resources of the demolition project sometimes translate into poor work planning and safety precautions. In recent years, demolition work has become more complicated due to the high diversity of building types and there are various demolition techniques and strategies. It is important to have a clear understanding of the type of building to be demolished, the method to be used and risks involved to ensure proper work planning. Using historical data on demolition related accidents; this paper discusses the classification of injuries and causes of the accidents. To conclude, strategies for better understanding of demolition work and good practices of site safety are recommended.

Pathways to female sexual offending : approach or avoidance?

This study forms the second part of a larger investigation into the offence process characteristics of female sexual offenders (FSOs). In the first part - documented in Gannon, Rose, and Ward (Sexual Abuse: A Journal of Research and Treatment, 20, 352-374, 2008) - we described the development of the Descriptive Model of Female Sexual Offending (DMFSO); an offence process model developed using Grounded Theory methodology to describe the sequence of cognitive, affective, behavioural and contextual factors generating female-perpetrated sexual abuse. The second study described here examines the prevalence of specific pathways characterizing the 22 FSOs originally used to develop the DMFSO. Four individuals could not be assigned to a pathway due to lack of information (18% of the overall sample). However, for the remaining 18 participants, three stable pathways to female sexual offending were identified: Explicit Approach offenders (50%, n=9), who intended to offend, and explicitly planned their offence behaviours accordingly; Directed Avoidant offenders (28%, n=5), who did not intend to offend, but did so under the direction and coercion of a male accomplice; and Implicit Disorganized offenders (22%, n=4), who did not intend to offend (i.e. they engaged in minimal planning), but offended impulsively following severe self-regulatory failure. In this paper, we present the core characteristics defining each pathway, their associated demographic features, and discuss potential treatment implications.

Tax planning, avoidance and evasion in Australia 1970-2010 : the regulatory responses and taxpayer compliance

This article examines tax avoidance strategies used by Australian taxpayers over the last four decades and analyses the regulatory responses by the government, noting a move away from the ‘command-and-control’ approach of the 1980s towards one of ‘responsive regulation’ and ‘meta risk management’. It is argued that despite inherent complexity issues, this regulatory approach has nevertheless contributed to the fostering of trust and a perception of fairness in the Australian tax system.

Gaming maching addiction : the role of avoidance, accessibility and social support

Commonality in etiology and clinical expression plus high comorbidity between pathological gambling and substance use disorders suggest common underlying motives. It is important to understand common motivators and differentiating factors. An overarching framework of addiction was used to examine predictors of problem gambling in current electronic gaming machine (EGM) gamblers. Path analysis was used to examine the relationships between antecedent factors (stressors, coping habits, social support), gambling motivations (avoidance, accessibility, social) and gambling behavior. Three hundred and forty seven (229 females: M = 29.20 years, SD = 14.93; 118 males: M = 29.64 years, SD = 12.49) people participated. Consistent with stress, coping and addiction theory, situational life stressors and general avoidance coping were positively related to avoidance-motivated gambling. In turn, avoidance-motivated gambling was positively related to EGM gambling frequency and problems. Consistent with exposure theory, life stressors were positively related to accessibility-motivated gambling, and accessibility-motivated gambling was positively related to EGM gambling frequency and gambling problems. These findings are consistent with other addiction research and suggest avoidance-motivated gambling is part of a more generalized pattern of avoidance coping with relative accessibility to EGM gambling explaining its choice as a method of avoidance. Findings also showed social support acted as a direct protective factor in relation to gambling frequency and problems and indirectly via avoidance and accessibility gambling motivations. Finally, life stressors were positively related to socially motivated gambling but this motivation was not related to either social support or gambling behavior suggesting it has little direct influence on gambling problems.

Aquatic plant shows flexible avoidance by escape from tuber predation by swans

Deeper burial of bulbs and tubers has been suggested as an escape against below-ground herbivory by vertebrates, but experimental evidence is lacking. As deep propagule burial can incur high costs of emergence after dormancy, burial depth may represent a trade-off between sprouting survival and herbivore avoidance. We tested whether burial depth of subterraneous tubers is a flexible trait in fennel pondweed (Potamogeton pectinatus), facing tuber predation by Bewick's swans (Cygnus columbianus bewickii) in shallow lakes in winter. In a four-year experiment involving eight exclosures, winter herbivory by swans and all vertebrate summer herbivory were excluded in a full-factorial design; we hence controlled for aboveground vertebrate herbivory in summer, possibly influencing tuber depth. Tuber depth was measured each September before swan arrival and each March before tuber sprouting. In accordance with our hypothesis, tuber depth in September decreased after excluding Bewick's swans in comparison to control plots. The summer exclosure showed an increase in tuber biomass and the number of shallow tubers, but not a significant effect on the mean burial depth of tuber mass. Our results suggest that a clonal plant like P. pectinatus can tune the tuber burial depth to predation pressure, either by phenotypic plasticity or genotype sorting, hence exhibiting flexible avoidance by escape. We suggest that a flexible propagule burial depth can be an effective herbivore avoidance strategy, which might be more widespread among tuber forming plant species than previously thought.

Australian school canteens: menu guideline adherence or avoidance?

Since 2005, all states and territories across Australia have progressively introduced policy guidelines to promote nutritious food sales in school canteens. This study aimed to assess the compliance of school canteens with their state or territory canteen guidelines.

Heritage rights - avoidance and reinforcement

 The conflicts that abound around the world between different groups struggling to control the definition, management, and use of heritage give rise to many issues that need to be foregrounded in scholarly and professional debates. Focusing on UNESCO’s World Heritage system, this paper asks: Why and how do nation states avoid respecting heritage rights? What can be and is being done about it? How can we move toward a more rightsbased approach to heritage management? The notion that people have rights to access and enjoy their cultural heritage has emerged within the domain of cultural rights, which, in turn, is a component of human rights. Prospects for achieving global recognition of cultural heritage rights have improved recently through interrelated activities being undertaken at the United Nations High Commission for Human Rights, in a Norwegian network of heritage, environmental and rights agencies, and at the United Nations Permanent Forum on Indigenous Issues. These advances relate mostly to Indigenous heritage, whereas the cultural heritage of other groups, such as women, children, and youth, or, in many parts of the world, ethnic and racial minorities that are not considered Indigenous peoples, lack comparable recognition and respect. © W.

Serotonergic neurons in the median raphe nucleus regulate inhibitory avoidance but not escape behavior in the rat elevated T-maze test of anxiety

Rationale: A wealth of evidence supports the involvement of the serotonergic neurons of the median raphe nucleus (MRN) in anxiety. However, it is presently unclear whether serotonergic pathways arising from this nucleus play distinguishing regulatory roles in defensive behaviors that have been associated with specific subtypes of anxiety disorders. Objectives: To evaluate the role of the MRN serotonergic neurons in the regulation of two defensive behaviors, inhibitory avoidance and escape, which have been related, respectively, to generalized anxiety and panic disorders. Methods: Male Wistar rats were submitted to the elevated T-maze test of anxiety after intra-MRN administration of drugs that either non-selectively or selectively change the activity of the serotonergic neurons. Results: Intra-MRN injection of FG 7142 (0.04 and 0.08 nmol) and kainic acid (0.03 and 0.06 nmol), drugs that non-selectively stimulate the MRN serotonergic neurons, facilitated inhibitory avoidance acquisition, but impaired escape performance. Microinjection of muscimol (0.11 and 0.22 nmol), a compound that non-selectively inhibits the activity of the MRN serotonergic neurons, impaired inhibitory avoidance and facilitated escape performance. Both kainic acid and muscimol also changed rat locomotion in the open-field test. Intra-MRN injection of 8-OH-DPAT (0.6-15 nmol) and WAY-100635 (0.18-0.74 nmol), respectively an agonist and an antagonist of somatodendritic 5-HT1A receptors located on serotonergic neurons of the MRN, only affected inhibitory avoidance-while the former inhibited the acquisition of this behavior, the latter facilitated it. Conclusion: MRN serotonergic neurons seem to be selectively involved in the regulation of inhibitory avoidance in the elevated T-maze. This result supports the proposal that 5-HT pathways departing from this nucleus play an important role in anxiety processing, with implications for pathologies such as generalized anxiety disorder.
