Comparing perceived listening behavior differences between managers and nonmanagers living in the United States, India, and Malaysia
No full textMany managers and employees work in multinational organizations, but know little about what constitutes good or bad listening skills from a cross-cultural perspective. Little literature exists concerning the listening behaviors of managers and nonmanagers or the impact of national culture on listening skills. No clear understanding of what constitutes effective and ineffective listening across various cultures and organizational positions is known. Therefore, this study examines the listening skills of both managers and nonmanagers from India, the United States, and Malaysia. A total of 513 managers and nonmanagers from these countries completed a survey measuring self-perceptions of their engagement in four listening behaviors: distracted listening, empathetic listening, judgment rushing, and conclusion jumping. An analysis of variance procedure, with a 2 × 3 factorial design, was used to ascertain whether differences existed when each of the four derived factors was used one at a time as a dependent variable. The two independent variables were managers/nonmanagers and country of residence. The means differed on the main effects of managers/nonmanagers (p \u3c .001) and country of residence (p \u3c .001) and interaction between managers and nonmanagers across the United States, India, and Malaysia (p \u3c .001) on all four factors. Therefore, perceptions of engaging in distracted listening, empathetic listening, judgment rushing, and conclusion jumping are different for managers and nonmanagers living in the United States, India, and Malaysia. This study’s findings will help both managers and nonmanagers from these countries understand the positives and negatives of these four listening practices and the influence of national culture on listening behaviors
Enhancing extension and research activities through the use of web GIS
No full textThere have been numerous efforts aimed at improving geographic literacy in order to address societal challenges. Extension educators can use geographic information system (GIS) technology to help their clients cultivate spatial thinking skills and solve problems. Researchers can use it to model relationships and better answer questions. A program at Prairie View A&M University involves the use of virtual, field, and story map activities associated with Web GIS (online mapping) to expose participants to plant species identification and engage them in spatial thinking. We describe that program and demonstrate the utility of Web GIS as a tool for integrating experiential learning in agro-environmental sciences
Religious Fundamentalism and Attitudes toward the Insanity Defense: The Mediating Roles of Criminal Attributions and Attitudes toward the Mentally Ill
No full textReligious fundamentalism typically has been associated with negative perceptions of the insanity defense and defendants who use it. This association also has translated into verdict and sentencing decisions in insanity cases, such that higher endorsement of fundamentalist beliefs was associated with more punitive decisions. However, the mechanisms underlying the relationship between fundamentalism and insanity defense attitudes is unclear. Two possible explanations for this relationship include that (a) fundamentalism is associated with more dispositional attributions, and (b) fundamentalism is associated with more authoritarian attitudes toward mental illness and the mentally ill. Using structural equation modeling, attributions and attitudes were tested as mediators of the relationship between fundamentalism and insanity defense attitudes (i.e., strict liability attitudes and injustice–danger attitudes). These relationships were examined for theists and nontheists separately. Results suggest that personal attributions mediate the relationship between fundamentalism and injustice–danger attitudes, but authoritarian attitudes mediated the relationship between fundamentalism and strict liability attitudes. These relationships were only significant for theists. Implications for research and practice are discussed at the end
Characterization of hydroxyapatite/polypyrrole/poly (caprolactone) based solvent cast thin films
No full textThis study addressed the fabrication of thin films composed of Polypyrrole (PPy), hydroxyapatite (HA) and poly (ε-caprolactone) (PCL) via solvent casting method. The polymer and composite films were subsequently characterized in terms of morphology, wettability and water uptake properties using different techniques. The characterization of the thin films were determined using a Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), water contact angle and water uptake. The addition of HA and PPy reduced the hydrophobic properties of PCL in the thin films. An energy dispersive x-ray (EDX) analysis supported the existence of HA in composite thin films. Water uptake of PCL thin film was lower than HA/PCL and HA/PPy/PCL composite thin films
Population-level effectiveness of PMTCT Option A on early mother-to-child (MTCT) transmission of HIV in South Africa: Implications for eliminating MTCT
No full textBackground Eliminating mother-to-child transmission of HIV (EMTCT), defined as ≤ 50 infant HIV infections per 100 000 live births, is a global priority. Since 2011 policies to prevent mother-to-child transmission of HIV (PMTCT) shifted from maternal antiretroviral (ARV) treatment or prophylaxis contingent on CD4 cell count to lifelong maternal ARV treatment (cART). We sought to measure progress with early (4-8 weeks postpartum) MTCT prevention and elimination, 2011-2013, at national and sub-national levels in South Africa, a high antenatal HIV prevalence setting (≈ 29%), where early MTCT was 3.5% in 2010. Methods Two surveys were conducted (August 2011-March 2012 and October 2012-May 2013), in 580 health facilities, randomly selected after two-stage probability proportional to size sampling of facilities (the primary sampling unit), to provide valid national and sub-national-(provincial)- level estimates. Data collectors interviewed caregivers of eligible infants, reviewed patient-held charts, and collected infant dried blood spots (iDBS). Confirmed positive HIV enzyme immunoassay (EIA) and positive total HIV nucleic acid polymerase chain reaction (PCR) indicated infant HIV exposure or infection, respectively. Weighted survey analysis was conducted for each survey and for the pooled data. Findings National data from 10 106 and 9120 participants were analyzed (2011-12 and 2012-13 surveys respectively). Infant HIV exposure was 32.2% (95% confidence interval (CI) 30.7-33.6%), in 2011-12 and 33.1% (95% CI 31.8-34.4%), provincial range of 22.1-43.6% in 2012- 13. MTCT was 2.7% (95% CI 2.1%-3.2%) in 2011-12 and 2.6% (95% CI 2.0-3.2%), provincial range of 1.9-5.4% in 2012-13. HIV-infected ARV-exposed mothers had significantly lower unadjusted early MTCT (2.0% [2011-12: 1.6-2.5%; 2012-13:1.5-2.6%]) compared to HIV-infected ARV-naive mothers [10.2% in 2011-12 (6.5-13.8%); 9.2% in 2012-13 (5.6-12.7%)]. Pooled analyses demonstrated significantly lower early MTCT among exclusive breastfeeding (EBF) mothers receiving \u3e 10 weeks ARV prophylaxis or cART compared with EBF and no ARVs: (2.2% [95% CI 1.25-3.09%] vs 12.2% [95% CI 4.7-19.6%], respectively); among HIV-infected ARV-exposed mothers, 24.9% (95% CI 23.5- 26.3%) initiated cART during or before the first trimester, and their early MTCT was 1.2% (95% CI 0.6-1.7%). Extrapolating these data, assuming 32% EIA positivity and 2.6% or 1.2% MTCT, 832 and 384 infants per 100 000 live births were HIV infected, respectively. Conclusions: Although we demonstrate sustained national-level PMTCT impact in a high HIV prevalence setting, results are far-removed from EMTCT targets. Reducing maternal HIV prevalence and treating all maternal HIV infection early are critical for further progress
Conductive PEDOT:PSS coated polylactide (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) electrospun membranes: Fabrication and characterization
No full textIn the current study, electrospinning technique was used to fabricate composite membranes by blending of a synthetic polymer, polylactic acid (PLA) and a natural polymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV. Conductive membranes were prepared by dipping PLA/PHBV electrospun membranes into poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) solution, which is a biocompatible polymer. The coated and uncoated membranes were evaluated using several techniques. The electrical conductivity of the coated membranes was measured using a digital multimeter. In vitro cell cytotoxicity and cell viability were measured by culturing human skin fibroblast (HSF) cells onto the membranes using MTT assays. It was observed that electrospinning of 20% (w/v) PLA/PHBV with a weight ratio of 50:50 produced the most uniform fibers with no beads. It was observed that the wettability and surface roughness of the PEDOT:PSS coated PLA/PHBV membranes were greatly increased than uncoated membrane. The results of cell viability using MTT assay, cell attachment and cell proliferation showed that the conductive PEDOT:PSS coated PLA/PHBV membrane were more favorable for tissue engineering application than their uncoated counterparts
How significant is durability in vernacular house construction?
No full textFor centuries, dynamic vernacular society has experienced repairing, or demolishing old houses, and constructing new houses. The time interval between those actions probably became more sparsely spread as modern and more durable technologies and materials offered wider range of options in the vernacular construction through globalization. The first objective of this paper was to compare the durability of distinctively old and new construction materials and technologies used in the vernacular houses in a context of northern Iran. The second objective was to search implicit values behind making decisions regarding durability. The ‘old’ construction technologies were ‘Kali’, Mud Houses, and Lar deh ee”, and, while Load-bearing wall, Concrete, and Steel structure were the ‘new’ categories. A questionnaire-based survey was conducted among 167 residents of different vernacular houses and 18 of them were selected for interview. Besides, a number of 20 experts also participated in a mailing survey for validating the data. Perception of users on durability of structure was assessed and compared through 5 elements namely foundation, floor, wall, roof, and attachment through the structured-questionnaire, while the implicit values were revealed from data collected through the open-ended interview. Results showed that residents tend to rate the old houses higher, rather controversially. Commercialization might be gradually inclining users’ choices towards new houses, but responses also showed that a house is likely to be redundant after only a couple of generations, even though it still has a long durable lifetime to spare, thus making the durability issue less significant
3-Total Super Sum Cordial Labeling by Applying Operations on some Graphs
Get PDFThe sum cordial labeling is a variant of cordial labeling. In this paper, we investigate 3-Total Super Sum Cordial labeling. This labeling is discussed by applying union operation on some of the graphs. A vertex labeling is assigned as a whole number within the range. For each edge of the graph, assign the label, according to some definite rule, defined for the investigated labeling. Any graph which satisfies 3-Total Super Sum Cordial labeling is known as the 3-Total Super Sum Cordial graphs. Here, we prove that some of the graphs like the union of Cycle and Path graphs, the union of Cycle and Complete Bipartite graph and the union of Path and Complete Bipartite graph satisfy the investigated labeling and hence are called the 3-Total Super Sum Cordial graphs
