Social Psychological Perspectives of Workforce Diversity and Inclusion in National and Global Contexts

The recent focus on diversity in themanagement literature takes on special urgency in the context of human services organizations. Human services organizations have traditionally served a wide array of communities with a high representation of diverse, disadvantaged, and oppressed groups. This diversity has not typically been mirrored in the workforce of those organizations. A recent study of a nationally representative sample of 10,000 social workers demonstrates that the profession is not keeping pace with the population it serves in terms of its ability to attract social workers of color (National Association of Social Workers, 2005). The study’s findings indicate that 86% of licensed social workers are predominantly nonHispanic whites. Both African Americans and Latinos are underrepresented relative to their presence in the U.S. population, with 7% African American social workers, compared to 12% in the population, and 4% Latinos, compared to 14% in the population. This workforce data stands in contrast to the social workers’ reports about the diversity of their client population: 83% report having black/African American clients in their caseloads and 75% report having Hispanic/ Latino clients. In the field of child protective services, agencies have been recruiting professionals outside of social work in order to increase the presence of underrepresented groups in their workforce (Clark & Jacquet, 2003). Despite advancement in the representation of women and members of minority groups in the human services workforce, there is still a lot to be done to make the workplace more inclusive. The extent to which workers from diverse Social Psychological Perspectives of Workforce Diversity and Inclusion in National and Global Contexts
The truth about peer review

espite some questioning, peer review remains an essential part of the practice of scientific publishing. Indeed, the first Recommendation approved at the ICSU/ UNESCO Conference of Experts on Electronic Publishing in Science in 1996 was that ‘strict peer review should be applied to all scientific material submitted for publication in electronic journals. ’ In the present context, peer review refers to the anonymous peer review of articles carried out on a confidential basis by referees chosen by the editor or editorial board. The identity of the referees is withheld from the authors, unlike the ‘open’ process advocated by some in which the entire exercise is carried out in public view. Anonymous peer review remains the selection process preferred by most journals, despite some acknowledged drawbacks. The authors trust the editor/s to choose expert referees who can be relied upon to produce an objective assessment of the manuscript, and, by and large, the system works. Occasionally a referee may fail to act objectively and betray bias of some kind. Then the editor seeks further advice elsewhere and drops that referee from the list of advisors. That is why it is customary to seek several reviews of each manuscript submitted in order to ensure objectivity and fair treatment. If this end is not achieved, then word gets around and the reputation of the journal suffers, which does no one any good. While the preceding brief description of refereeing may be regarded as common knowledge and thus unnecessary, it serves to underline the point that the system is labour-intensive and expensive. And if needy learned societies and publishers continue to devote their energies and scarce resources to this activity then they The truth about peer review
RESONANT FREQUENCY TRACKING CONTROL BY IZL (INTEGRATED ZERO LOOP)

This paper presents a novel resonant frequency tracking control method for the full bridge type high frequency inverter. The proposed method uses only one ac current transformer though a general PLL as a frequency control method uses 2 current or potential transformers. Furthermore, the high frequency inverter system does not need to employ an active converter to control the DC bus voltage for the output power regulation although the inverter system using PLL has to have an active converter. Accordingly, the inverter that installs the proposed control method can control the operation frequency adequate and regulate the output power by one converter system. Hence, the high frequency inverter that is used for changing reactance load like an induction heating load can be simplified by introducing the proposed frequency control method. He operation principle is illustrated with a sample of block diagram. Simulation is implemented to estimate the control method and its results shoe a good performance for tuning the operation frequency to the resonant frequency. In addition, the control method is installed in an actual inverter for high power induction heating application. Observed and measured results verify the performance of the proposed frequency control method.
Qualitative analysis of mediated communication experience

We studied the experiences of participants collaborating in video and teleconference situations. We utilized a qualitative experience measurement methodology where participants freely described their experiences by giving attributes that best described their experience. The most frequent descriptions were combined to attributes which were used to discriminate the experimental conditions. The results indicated that qualitative methodology can discriminate the experience differences between mediated communication technologies. Videoconferencing setting was described as the most natural and exciting, while teleconferencing was described as confusing and frustrating. The results also showed that utilization of face-to-face situation as a comparison condition to mediated communication situations can be problematic, because the meaning of experience attributes changes.
Characterization of Human CD4+ T-Cell Clones Recognizing Conserved and Variable Epitopes of the Lassa Virus Nucleoprotein

ABSTRACT T cells must play the major role in controlling acute human Lassa virus infection, because patients recover from acute Lassa fever in the absence of a measurable neutralizing antibody response. T cells alone seem to protect animals from a lethal Lassa virus challenge, because after experimental vaccination no neutralizing antibodies are detectable. In order to study human T-cell reactivity to single Lassa virus proteins, the nucleoprotein (NP) of Lassa virus, strain Josiah, was cloned, expressed in Escherichia coli, and affinity purified. Peripheral blood mononuclear cells (PBMC) obtained from 8 of 13 healthy, Lassa virus antibody-positive individuals living in the Republic of Guinea, western Africa, were found to proliferate in response to the recombinant protein (proliferation index ≥10). PBMC obtained from one individual with a particularly high proliferative response were used to generate 50 NP-specific T-cell clones (TCC). For six of these the epitopes were mapped with overlapping synthetic peptides derived from the sequence of the NP. These CD4+TCC displayed high specific proliferation and produced mainly gamma interferon upon stimulation with NP. Because variation of up to 15% in the amino acid sequences of the structural proteins of naturally occurring Lassa virus variants has been observed, the reactivity of the TCC with peptides derived from the homologous epitopes of the Nigeria strain of Lassa virus and of the eastern Africa arenavirus Mopeia was tested. With the Nigeria strain of Lassa virus the levels of homology were 100% for two of these epitopes and 85% for three of them, whereas homology with the respective Mopeia epitopes ranged from 92 to 69%. Reactivity of the TCC with peptides derived from the variable epitopes of the Nigeria strain and of Mopeia was reduced or completely abolished. This report shows for the first time that seropositive individuals from areas of endemicity have very strong memory CD4+ T-cell responses against the NP of Lassa virus, which are partly strain specific and partly cross-reactive with other Lassa virus strains. Our findings may have important implications for the strategy of designing recombinant vaccines against this mainly T-cell-controlled human arenavirus infection.
Antimicrobial Peptides: An Emerging Approach to Treating Colitis

Antimicrobial peptides are endogenous peptides typically expressed on mucosal surfaces, such as the mouth, intestines, and respiratory tract. These mucosal surfaces are typically in close contact with the external environment and microbiota. Over the last decade, the role of antimicrobial peptides in colitis has become increasingly apparent, and some antimicrobial peptides show promise as future therapeutic approaches to treat colitis. Pharmaceutical companies and laboratories are developing clinically useful versions of antimicrobial peptides with high efficacy, robust chemical stability, and excellent safety profile.
Isolation, Identification and Screening of Endophytic Bacteria Antagonistic to Biofilm Formers

An array of 76 endophytic bacterial isolates obtained from different plant tissues including root, stem and fresh and wilted leaves of various plants in Punjab, Pakistan were investigated for their antagonistic ability to biofilm formers. The morphological, biochemical and physiological characterization and 16S rRNA gene sequence analysis of the selected endophytic isolates leads to the identification of different bacterial species belonging to the genera Bacillus, Pseudomonas, Serratia, Stenotrophomonas and Micromonospora. The isolates exhibited potent antimicrobial activity against biofilm forming bacterial strains in biological screening by agar diffusion assay. In chemical screening, the crude extracts obtained from each of the isolate and analyzed by thin layer chromatography (TLC) using various spraying reagents and by HPLC-UV, exhibited an impressive chemical diversity of the bioactive secondary metabolites. The antimicrobial activity and the chemical diversity exhibited by these endophytic bacterial strains demonstrate that they are a promising source of useful/novel antimicrobial agents, to control the infections caused by biofilm forming bacterial species.
Chromatin modifications: implications in the regulation of gene expression in Toxoplasma gondii

The apicomplexan Toxoplasma gondii completes its life cycle by successive processes of parasite differentiation that rely on a tight control of gene expression to ensure appropriate protein profiles on time. During the last 5 years, several groups have pioneered this field of investigation, suggesting that epigenetics could play an important role in the control of parasite gene expression. Histone modifications serve as an effective way to regulate gene transcription but they do not operate alone; rather, they act in concert with other putative epigenetic information carriers (histone variants, small RNAs) and DNA sequence‐specific transcription factors to modulate the higher‐order structure of the chromatin fibre and govern the on‐time recruitment of the transcriptional machinery to specific genes. Regarding the ‘histone code’ hypothesis, the parasite is endowed with a rich repertoire of histone‐modifying enzymes catalysing site‐selective modifications, which are subsequently interpreted by effector proteins that recognize specific covalent marks. Still, several peculiarities seem unique to T. gondii. This review is a synthesis of the current knowledge of how epigenetics contribute to the control of gene expression in T. gondii and, likely, other Apicomplexa.
Assay of Tissue Activity of Nitric Oxide Synthase

Nitric oxide synthase activity can be assayed by a variety of methods. The simplest method to assay activity is the conversion of radiolabeled L‐arginine to L‐citrulline. The assay described in this unit is sensitive, simple to perform, is relatively robust, and can be performed with intact monolayer or suspension cells, or with cell or tissue extracts. The product is easily separated from the reaction by cation‐exchange chromatography.
Country material distribution and adolescents’ perceived health: multilevel study of adolescents in 27 countries

Objective: To assess the impact of country material distribution on adolescents’ perceptions of health. Design: Cross sectional multilevel study. Setting: Data were collected from the school based health behaviour in school aged children: WHO cross national study 1997/98, which includes students from 27 European and North American countries. Participants: 12 0381 students in year 6, 8, and 10 who were attending school classes on the day of data collection. Main result: Adolescents in countries with a high dispersion of family affluence were more likely to have self rated poor health even after controlling for individual family level of affluence and family social resources. Conclusion: There are substantial inequalities in subjective health across European and North American countries related to the distribution of family material resources in these countries.
Simulation and back-to-back testing of synchronous machine

The dynamic properties of back-to-back single supply high power salient poles synchronous machine are analyzed by modeling and simulation. The considered mathematical model is convenient for high power salient poles synchronous machines. The dynamic electromagnetic torques and windings currents where particularly considered. Of a special concern is also the steady state operation. This issue is of theoretical and practical interest in the field of electrical machines, especially high power, and there are no detailed references in literature. Simulations and experiments confirm the possibility of synchronous operation. The recoverable character of operation is fundamental. The proposed test method at rated load is experimentally validated. It is quite appropriate for high power machines, comparing with other methods.
Load interval forecasting methods based on an ensemble of Extreme Learning Machines

In this paper, three individual indices, as well as a new comprehensive index, are introduced to evaluate prediction intervals. Then, two practical methods, namely, Interval Extension Method and Optimal Scalar Method are proposed to build the prediction intervals based on an ensemble of Extreme Learning Machines. Case studies on hour-ahead load interval forecasting with respect to Chicago Metro Area are conducted, results of which illustrate that the proposed two methods are able to build high-quality prediction intervals and Optimal Scalar Method tends to have better performance.
Adhesion of Bordetellapertussis to Sulfatides and to the GalNAcp 4 Gal Sequence Found in Glycosphingolipids *

The adherence of the human respiratory pathogen, Bordetella pertussis, to purified glycosphingolipids was investigated using thin layer chromatography overlay assays. Both virulent and avirulent strains of B. pertussis bound to asialo G M ~ . The bacterium did not bind to the gangliosides G M 1 , GDI,, %It,, and G ~ l b , nor to lactosylceramide, trihexosylceramide, globoside, or Forssman antigen. However, after treatment of the chromatography plates with sialidase, B. pertussis bound to the gangliosides GMI? G M ~ ? GDI,, GDlt,, and GTlb but not to G M ~ . Comparison of the oligosaccharide structures of these gangliosides suggests that the minimum sugar structure needed for avid bacterial binding is GalNAcB4Gal. This stucture has been previously implicated as a receptor for other human respiratory pathogens (Krivan, H. C., Roberts, D. D., Ginsburg, V. (1988) Proc. Natl. Acad. Sei. U. S. A 85,6157-6161). Virulent strains of B. pertussis also bound specifically to sulfatide. This response was dose-dependent and inhibited by the anionic polysaccharide dextran sulfate. The sulfated-sugars dextran sulfate, fucoidan, and heparin inhibited the attachment of virulent strains of B. pertussis to human WiDr cells and to hamster trachea cells indicating that sulfatides on the surface of mammalian cells may function as a receptor for B. pertussis. The occurrence of both sulfatides and asialo GMl in human lung and trachea suggests that these glycolipids may serve as specific receptors for B. pertussis.
Predicting longitudinal changes in caregiver physical and mental health: a stress process model.

Alzheimer's family caregivers (N = 122) reported on physical and mental health, as well as stress process variables, at baseline and at a 1-year follow-up. Hierarchical regression analyses of stress process models revealed that increases in primary stressors (e.g., patient self-care and behavioral problems) did not directly affect changes in the mental and physical health outcome variables. However, analyses of models of direct, mediated, and moderated effects revealed that psychosocial resource variables (appraisals, coping responses, and social support) were related to caregiver outcomes over time through several mechanisms. In particular, benign appraisals of stressors, the use of approach coping, and greater levels of social support were associated with more positive caregiver health outcomes over time.
Femoral plating.

We have demonstrated that we are able to meet both trauma and orthopedic goals with immediate plate fixation of femoral fractures in patients with blunt polytrauma. Our femoral fracture mortality rate is less than our predicted institutional mortality rate of patients with comparative injury severity scores. Ipsilateral femoral neck and shaft fractures are easily repaired with femoral plating. Infections, even in open fractures and systemically unstable patients, are rare. Implant failures have been infrequent and are easily reconstructed with intramedullary nails. Knee motion has been restored reliably. Stainless steel DCP plate fixation requires primary bone grafting. Achieving union and subsequent knee rehabilitation often requires that patients remain on crutches for up to 6 months. Our experience with titanium LCDCP plates is preliminary, but we are seeing a significant amount of callus formation and, perhaps, earlier union and bearing weight.
SIMULATION OF WIND EFFECT ON A QUADROTOR FLIGHT

Different disturbances should be taken into account to solve the quad rotor flight control problem. Wind effect is a disturbance in a quad rotor flight control system. A model of wind effect on quad rotor flight was developed in this paper. The model is a number of elements: the model of wind velocity change, the model of a gust (“wind step”), the model of wind velocity change depending on a flight altitude, the model of wind direction change. The model of wind velocity change takes into account wind velocity increasing and decreasing. The wind force expression depending on the effective influence area on a quad rotor was derived. The steps of the wind disturbances simulation algorithm are given here.

Analysis of Power Consumption of H.264/AVC-based Video Sensor Networks through Modeling the Encoding Complexity and Bitrate

—The H.264/AVC video encoding standard has many advanced features that can be tailored to suit a wide range of applications. In order to obtain optimal coding performance in video sensor networks (VSNs), it is essential to find the right setting parameters for the encoder. There is a trade-off between required energy for encoding and transmission of video content in VSNs that can be exploited to minimize total power consumption. In this study, we model the complexity and bitrate in H.264/AVC codec. By using the model, the trade-off between encoding and transmission energy consumption is further exploited. Our experiments show that the complexity modeling error is less than or equal to 3.45%. However, the bitrate modeling error that we obtain is less than or equal to 11.6%.
Smoking and depression: a community survey.

Smoking status and symptoms of mental depression were determined as part of a community survey of adults in Los Angeles County. Nearly 42 per cent of the males and 31 per cent of the females wee current smokers. Smokers compared to nonsmokers reported significantly higher levels of depression as measured by the Center for Epidemiologic Studies--Depression (CES-D) index (10.02 vs 8.76, p < .05). The differences were not significant, however, when analyzed by sex. Furthermore, there were no significant differences in the CES-D score when comparing those who had never smoked, ex-smokers, current smokers who wanted to quit, and current smokers who did not want to quit. After controlling in a linear regression analysis for the effects of income, age, employment status, and sex, none of the smoking status variables contributed significantly to explaining the variance of the CES-D score. While both mental depression and smoking are individually major public health problems, the results of this investigation suggest that there is little relationship between the two in the general community.
Einkommensungleichheit in der Bundesrepublik Deutschland : Diskriminierung von Frauen und Ausländern?

"Der Artikel befast sich mit einer empirischen Untersuchung der Einkommensunterschiede zwischen Mannern und Frauen sowie zwischen Deutschen und Auslandern in der Bundesrepublik Deutschland. Anhand der Daten des Mikrozensus 1985 werden humankapitaltheoretisch fundierte Einkommensfunktionen geschatzt. Der Stichprobenauswahlfehler wird durch die Heckman-Korrektur berucksichtigt. Insbesondere wird der Frage nachgegangen, inwieweit die beobachteten geschlechts- und nationalitatsbedingten Einkommensdifferenzen auf Unterschiede in den individuellen Humankapitalausstattungen zuruckzufuhren sind und in welcher Weise sich verschiedene Methoden der Berucksichtigung der Selektionskorrekturvariable bei der Einkommenszerlegung auf die Diskriminierungsschatzung auswirken. Es zeigt sich, das auch dann ein nennenswerter Diskriminierungsanteil verbleibt, wenn der Einkommensunterschied zwischen Frauen und Mannern um Unterschiede in der Ausbildung, Berufserfahrung, Arbeitszeit und der Erwerbsbeteiligung bereinigt wird. Die geschlechtsbezogene Diskriminierungskomponente erweist sich dabei als starker als das Ausmas der Diskriminierung nach Nationalitat. " (Autorenreferat, IAB-Doku)
