Latino social network dynamics and the Hurricane Katrina disaster

The aim of this qualitative research was to examine the dynamics of existing and emerging social networks among Latino survivors of Hurricane Katrina. Data were generated through individual, in-depth interviews conducted with 65 Latinos within six months of the storm striking the Gulf Coast of the United States in August 2005. The findings illustrated both the role of social networks in gathering information, making decisions and accessing resources, and how these existing social networks were disrupted and strained by overwhelming needs. Broader structural issues, including poverty and a lack of transportation, combined with marginalised status as immigrants, further constrained access to essential information and resources. In response, new, if temporary, social networks emerged, based primarily on shared nationality, language, and a sense of collective commitment. Practice implications include the need to consider the social network dynamics of marginalised groups in developing innovative strategies to overcome structural barriers to accessing resources essential for disaster preparedness and survival.     

Technician Training in Environmental Health Science

In colleges and universities across the country, courses in ecology and environmental science are among the newest additions to the catalog. The goal of such courses is to make students aware of the environmental dilemma, a just and necessary goal. However, there is a need to do more than this. Jobs dealing with environmental protection are becoming more and more complex due to the recent passage of State and Federal legislation, which includes the Clean Air Act, the Amendments to the Water Pollution Control Act and the Occupational Safety and Health Act, just to name a few. Trained personnel are needed by industry and government. For this reason, in 1971, Middlesex County College initiated an Environmental Health Science Technology Program.     

The role of design issues in work-related fatal injury in Australia

PROBLEM: This study aimed to provide an assessment of the contribution of design to the occurrence of fatal work-related injuries in Australia. METHODS: The Australian National Coroners' Information System was the data source for fatal injuries. Deaths resulting from workplace injuries on or between 1 July 2000 and 30 June 2002 were included. RESULTS: Seventy seven (37%) of the 210 identified workplace fatalities definitely or probably had design-related issues involved. In another 29 (14%), the circumstances were suggestive that design issues were involved. The most common scenarios involved problems with rollover protective structures and/or associated seat belts; inadequate guarding; lack of residual current devices; inadequate fall protection; failed hydraulic lifting systems in vehicles and mobile equipment; and inadequate protection mechanisms on mobile plant and vehicles. SUMMARY: Design is a significant contributor to work-related fatal injury in Australia. There is considerable scope for preventing serious work-related injury through improving design of plant, equipment, and vehicles used for work-related purposes.     

Invasive vermigon stage in the parasitic barnacles Loxothylacus texanus and L. panopaei (Sacculinidae): closing of the rhizocephalan life-cycle

 The parasitic barnacles, Rhizocephala, are unique in Crustacea by having an entirely endo-parasitic phase inserted into their lifecycle. A cypris larva, remarkably similar to the cypris of conventional acorn and goose barnacles (Thoracica), settles on the crustacean host and develops an infective stage, the kentrogon, underneath the exuviae of the cypris. The kentrogon penetrates the integument of the host by a hollow cuticle structure, the stylet, and injects the parasitic material into the hemocoelic fluid of the host. Although advanced stages of the internal development have been found and described several times, the nature of the originally injected parasitic material has remained obscure for decades. Recently, however, it was shown that the parasitic material was injected by the kentrogon in the form of a motile, multi-cellular and vermiform body. The present study demonstrates that the vermiform stage is an instar which forms the only and direct link between the kentrogon and the maturing internal parasite. The vermiform instar, or vermigon, is at all times clothed in a cuticle, contains several types of cells, including epidermis and the anlage of the later ovary, and stays intact while growing into the internal parasites with rootlets.

Reduced frequency and severity of residential fires following delivery of fire prevention education by on-duty fire fighters: cluster randomized controlled study

IntroductionIn 2008, Surrey Fire Services, British Columbia, commenced a firefighter-delivered, door-to-door fire-prevention education and smoke alarm examination/installation initiative with the intention of reducing the frequency and severity of residential structure fires in the City of Surrey.MethodHigh-risk zones within the city were identified and 18,473 home visits were undertaken across seven temporal delivery cohorts (13.8% of non-apartment dwellings in the city). The frequency and severity of fires pre- and post- the home visit intervention was examined in comparison to randomized high-risk cluster controls.ResultsOverall, the frequency of fires was found to have reduced in the city overall, however, the reduction in the intervention cohorts was significantly larger than for controls. Furthermore, when fires did occur within the intervention cohorts, smoke detectors were activated more frequently and the fires were confined to the object of origin more often post-home visits. No equivalent pattern was observed for the cluster control.Impact on IndustryOn-duty fire fighters can reduce the frequency and severity of residential fires through targeted, door-to-door distribution of fire prevention education in high-risk areas.

Moving Towards Sustainable Development? Integrating Economic Development and the Environment in Local Authorities

The recent growth of interest in sustainable development has led to the incorporation of the concept into policy making at a variety of scales. In all cases particular emphasis is placed upon the local scale as the focus for the implementation of policy and initiatives and especially upon local authorities as the major contributor to this process. There has been little assessment, however, of the extent to which local authorities either can, or are, undertaking such initiatives. This paper examines: the potential role that local authorities can play in integrating economic development and the environment; the forms of response and initiatives that are currently in place, drawing upon survey evidence from urban local authorities in England and Wales; and some of the limits to local authority action.     

Prenatal sonographic diagnosis of Malpuech syndrome

Malpuech syndrome (MS) is a rare autosomal recessive syndrome featuring pre- and post-natal growth deficiency, mental retardation, facial dysmorphism, cleft lip and palate (typically midline or bilateral), caudal appendage, renal malformations and male genital abnormalities. A prenatal diagnosis of MS was made in this fetus based on the family history and a combination of conventional and 3D prenatal ultrasound findings. The family were consanguineous with an affected first child. Prenatal ultrasound in the second pregnancy demonstrated bilateral cleft lip and palate in association with intrauterine growth retardation on serial prenatal ultrasound scans. Dysmorphic facial features and a small penis consistent with the diagnosis were confirmed on 3D scanning. Post-natal examination of the neonate confirmed the diagnosis of MS. To the best of our knowledge, this is the first prenatal diagnosis of this syndrome. Copyright © 2006 John Wiley & Sons, Ltd.
