The Role of Trust in Channels of Strategic Communication for Building Civil Society

In these turbulent times, development communication is a growing and important area of both academic research and practice. This article explores the role of strategic communication channels in the development of civil society in Bosnia. This case study reports the results of a survey that asked Bosnians about their levels of trust in government officials, alternative media, and state-controlled media outlets. The findings suggest that shortly after the war Bosnians had medium levels of trust in their communication channels, and when it comes to obtaining important information, it appears that alternative media were considered more trustworthy than either the state media or local government officials. Finally, political affiliation and ethnicity affect trust in communication channels in complex ways.     

Mental health services in Louisiana school-based health centers post-Hurricanes Katrina and Rita.

Following Hurricanes Katrina and Rita, Louisiana school-based health centers (SBHCs) were called on to respond to a sharp increase in mental health needs, especially for displaced students coping with grief, loss, trauma, and uncertainty. To assess the impact of the hurricanes on the students and the needs of SBHC mental health providers (MHPs), we surveyed MHPs in each of the SBHCs under the auspices of the Louisiana Department of Health and Hospitals, Office of Public Health. SBHC practitioners from around the state reported that mental health service utilization rose during the 2005-2006 school year, but utilization of services increased most significantly in schools receiving the majority of displaced students. Anxiety and adjustment problems were noted as increasing the most following the hurricanes. A multitude of other conditions was also reported. By the time of this survey in April 2006, the reported prevalence of most symptoms had declined, but all remained above their pre-hurricane levels. Self-reported needs of SBHC MHPs are also discussed in light of the major natural disasters. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Effectiveness of the Expected Value-Variance-Skewness Criterion in the Multi-Stage Capital Rationing Problem

It has been suggested that the skewness of the probability distribution of the net present value of an investment should be a consideration in judging its desirability. This paper presents an index, referred to as the Expected Value - Variance - Skewness criterion, that incorporates skewness of net present value with its expected value and variance as a measure of investment worth under risk. The effectiveness of this criterion was compared to the expected value and the expected value-variance decision criteria by applying each criterion in a long sequence of investment projects.     

Sustained attention in children with two etiologies of early hydrocephalus.

Several studies have shown that children with spina bifida meningomyelocele (SBM) and hydrocephalus have attention problems on parent ratings and difficulties in stimulus orienting associated with a posterior brain attention system. Less is known about response control and inhibition associated with an anterior brain attention system. Using the Gordon Vigilance Task (Gordon, 1983), we studied error rate, reaction time, and performance over time for sustained attention, a key anterior attention function, in 101 children with SBM, 17 with aqueductal stenosis (AS; another condition involving congenital hydrocephalus), and 40 typically developing controls (NC). In SBM, we investigated the relation between cognitive attention and parent ratings of inattention and hyperactivity and explored the impact of medical variables. Children with SBM did not differ from AS or NC groups on measures of sustained attention, but they committed more errors and responded more slowly. Approximately one-third of the SBM group had attention symptoms, although parent attention ratings were not associated with task performance. Hydrocephalus does not account for the attention profile of children with SBM, which also reflects the distinctive brain dysmorphologies associated with this condition.

The use of scanning electron microscope autoradiography to localize the blueberry shoestring virus in its aphid vector

Scanning electron microscopy autoradiography (SEM-AR) in conjunction with light microscope autoradiography (LM-AR) was used to follow the movement of ¹²⁵I-labeled blueberry shoestring virus (BBSSV) through its aphid vector Illinoia pepperi with varying acquisition access periods (AAP). At 6 hr AAP, the virus had reached the stomach; at 12 hr AAP, it had reached the anterior of the intestines, and after 48 hr, AAP was present throughout the aphid. SEM-AR using backscatter electron detection proved very useful because the sample bulk resulted in a shortened exposure time compared to LM sections, correlation of the autoradiograms could be made with fine structure, preparing large numbers of samples was easy, and examining whole longitudinal sections of aphids at low magnification with a clearly visible marker was possible. Limitations were mostly attributed to sample preparation and, in some cases, were easily remedied.     

Surface Mechanical Properties of the Spore Adhesive of the Green Alga Ulva

The mechanical properties of the adhesive produced by spores of the green, marine, fouling alga Ulva linza are reported. Atomic force microscopy studies were performed and nanoindentation data were analyzed using a model for an asymmetric indenter. Freshly secreted adhesive is characterized by multiple layers. We found that the modulus of the outer ∼600-nm thick layer was about 0.2 ± 0.1 MPa, whereas the modulus of the inner layer was about 3 ± 1 MPa. Older adhesive showed the formation of a “crust” of harder material with a yield strength of ∼20 MPa at a loading rate of 2.5 × 10^-6 N · s^-1. Mechanical properties under tension are also described, and extension profiles that showed either constant or nonlinear force changes with tip-sample separation were observed. Models for both kinds of behavior are described. The work of adhesion between poly-dimethylsiloxane (PDMS)-coated AFM tips and the adhesive was determined to be less than 1.5 mJ · m^-2.     

Depressive symptomatology during pregnancy: Evidence for an association with decreased fetal growth in pregnancies of lower social class women.

The relationship between depressive symptom scores on the Center for Epidemiological Studies Depression Scale (CES-D; L. S. Radloff, 1977) at each trimester of pregnancy and a decrement in either fetal growth or gestational duration was evaluated among 666 pregnant women. There was no association overall, but among 222 women from lower occupational status households, each unit increase on the CES-D at 28 weeks gestation was associated with a reduction of 9.1 g (95% confidence interval [CI]?=?–16.0, –2.3) in gestational-age-adjusted birth weight. When missing data were multiply imputed, the estimate was –4.6 g (95% CI?=?–10.7, 1.5). CES-D score was unrelated to fetal growth or gestational duration in analyses among other potentially high-risk subgroups: smokers, women with a history of adverse outcome, and women with social vulnerabilities. These results raise the possibility that among lower status women, depressive mood may be associated with restricted fetal growth. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Technological Intervention to Eliminate Back Injury Risks for Nailing

“Ergonomics” is derived from the Greek words “ergon,” meaning work, and “nomos,” meaning natural laws. Thus, one can interpret ergonomics as the “natural laws of work.” As documented in the literature, ergonomics has long been ignored by management and workers in construction alike. Unfortunately, a sore back in the evening is not always the effect of healthy hard work at the jobsite made apparent by the staggering cost of workers' compensation. Occupational back injuries result in more lost workdays than any other illness, secondly only to the common cold. In addition, manufacturers of construction tools have started to redesign their products because of liability concerns. This paper describes an effort that considers the health epidemic of back injuries as an opportunity. The basic premise is to apply the “natural laws of work” in a scientific manner to reach and treat the root of the problem and not its symptoms. Pneumatic nailing of subfloors is used to explain that back pain and the risk of back injuries for the average construction worker can be decreased, while at the same time maintaining short-term productivity and increasing long-term productivity.     

Issues to consider in conducting nonsexist psychological research: A guide for researchers.

Discusses the operation of sexism in all areas of psychological research, from broad conceptual issues to narrow methodological concerns. It is argued that sexism, in the form of unexamined assumptions about the sexes and unequal treatment of males and females may enter psychological research at any phase of a research project. Three major types of barriers to sex-fair research are identified: excessive confidence in traditional methods of research, bias in explanatory systems, and inappropriate conceptualization and operationalization. A series of recommendations are offered to eliminate some of the most common forms of sexist bias in research and to stimulate critical discussion of practices within psychology that encourage or fail to challenge sexist bias.
