The Effects of Supervisory Behavior on IT employees’ Job Satisfaction: An Exploratory Study

The purpose of the study is to influence positive motivational behaviors and expected satisfaction from the employees working at the organizations under close supervision. It has been monitored two supervisory behaviors on IT employees’ job satisfaction: authoritarian and positive achievement motivation behavior. Data were collected through pre-structured questionnaire from the employees working in the IT department of Real Estate and Hosing Development Industry in Bangladesh (N=80).   The data indicated that IT Supervisors were engaged in positive motivational behaviors and expected greater satisfaction from the employees under their supervision; IT employee’s job satisfactions were increased. Key words: Supervisory behavior, Job satisfaction, Organization Behavior

Double Carbon−Hydrogen Activation of 2-Vinylpyridine: Synthesis of Tri- and Pentanuclear Clusters Containing the μ-NC\u3csub\u3e5\u3c/sub\u3eH\u3csub\u3e4\u3c/sub\u3eCH═C Ligand

Reactions of 2-vinylpyridine with the triruthenium complexes [Ru3(CO)12] and [Ru3(CO)10(μ-dppm)] leads to a previously unknown double carbon−hydrogen bond activation of the β-carbon of the vinyl group to afford the pentaruthenium and triruthenium complexes [Ru5(CO)14(μ4-C5H4CH═C)(μ-H)2] (1) and [Ru3Cl(CO)5(μ-CO)(μ-dppm)(μ3-NC5H4CH═C)(μ-H)] (2), respectively. Crystal structures reveal two different forms of bridging of the dimetalated 2-vinylpyridyl ligand, capping a square face in 1 and a triangular face in 2

Dirhenium carbonyl compounds bearing cis-1,2-bis(diphenylphosphino)ethylene and cis-1,2-bis(diphenylphosphino)ethylene oxide ligands

1289-1295Reaction of [Re2(CO)9(MeCN)] with cis-1,2-bis(diphenylphosphino)ethylene (cis-Ph2PCH=CHPPh2) in boiling benzene (80 °C) afforded two compounds, ax-[Re2(CO)9(κ1-cis-Ph2PCH=CHPPh2)] (1) and ax-[Re2(CO)9{κ1-cis- Ph2PCH=CHPh2P(O)}] (2) where the ligand is axially coordinated in a κ1 monodentate fashion through phosphorus. The close-bridged compound eq-[Re2(CO)8(μ-κ2-cis-Ph2PCH=CHPPh2)] (3) is obtained from a similar reaction of the same ligand with [Re2(CO)8(NCMe)2] in refluxing benzene. In this case the diphosphine is equatorially coordinated to two Re atoms in a symmetrical bridging fashion. Compounds 1−3 have been characterized by IR, 1H NMR, 31P{1H} NMR spectroscopy and single crystal X-ray diffraction analyses

Effects of salinity on physiological, biochemical and gene expression parameters of Black Tiger Shrimp (Penaeus monodon): potential for farming in low-salinity environments

Salinity is one of the most important abiotic factors affecting growth, metabolism, immunity and survival of aquatic species in farming environments. As a euryhaline species, the black tiger shrimp (Penaeus monodon) can tolerate a wide range of salinity levels and is farmed between brackish to marine water conditions. The current study tested the effects of six different salinity levels (0‰, 2.5‰, 5‰, 10‰, 20‰ and 30‰) on the selected physiological, biochemical and genetic markers (individual changes in the expression pattern of selected candidate genes) in the black tiger shrimp. Experimental salinity levels significantly affected growth and survival performance (p < 0.05); the highest levels of growth and survival performance were observed at the control (20‰) salinity. Salinity reductions significantly increased free fatty acid (FFA), but reduced free amino acid (FAA) levels. Lower salinity treatments (0–10‰) significantly reduced hemolymph osmolality levels while 30‰ significantly increased osmolality levels. The five different salinity treatments increased the expression of osmoregulatory and hemolymph regulatory genes by 1.2–8-fold. In contrast, 1.2–1.6-fold lower expression levels were observed at the five salinity treatments for growth (alpha amylase) and immunity (toll-like receptor) genes. O2 consumption, glucose and serotonin levels, and expression of osmoregulatory genes showed rapid increase initially with salinity change, followed by reducing trend and stable patterns from the 5th day to the end. Hemocyte counts, expression of growth and immunity related genes showed initial decreasing trends, followed by an increasing trend and finally stability from 20th day to the end. Results indicate the farming potential of P. monodon at low salinity environments (possibly at freshwater) by proper acclimation prior to stocking with minimal effects on production performance

The compounds I and II have been characterized by IR, PMR, masss spectra and elemental analyses

Solid fuel use is a major risk factor for acute coronary syndromes among rural women: a matched case control study

OBJECTIVES: Almost half of the world\u27s population uses solid fuel for cooking, exposing women to high levels of particulate pollution in indoor air. The risk of acute coronary syndrome (ACS) was assessed among rural women, according to their use of solid fuel.STUDY DESIGN: Matched case control study.METHODS: Data were collected at a public tertiary care hospital in a rural district of Pakistan. Seventy-three women with ACS were compared with controls, individually matched for sex and age (± 5 years), who were admitted to hospital for other reasons. Fuels used for cooking and exposures to potentially confounding variables were ascertained through a questionnaire administered at interview and measurement of height and weight. Conditional logistic regression was used to estimate odds ratios (ORs) with 95% confidence intervals (95% CIs).RESULTS: After adjustment for potential confounding factors, current use of solid fuel was strongly associated with ACS (OR 4.8, 95% CI: 1.5-14.8), and risk was lowest in women who had last used solid fuel more than 15 years earlier. The population attributable fraction for ACS in relation to current use of solid fuel was 49.0% (95% CI: 41.3%-57.4%).CONCLUSIONS: These findings support the hypothesis that indoor air pollution from use of solid fuel is an important cause of ACS. Our study demonstrates the feasibility of case-control studies in rural populations of women to address this question, and is an encouragement to larger and statistically more powerful investigations

Compound 9, which exists as two isomers in solution, converts into 8 almost quantitatively in solution at 25 degreesC and more rapidly in refluxing hexane. Compound 8 reacts with H-2, at 110 degreesC to give 7 in high yield (86%). Treatment of 2 with propane-2-thiol yields [Os-3(CO)(8){mu -SCH(CH3)CH3} {Ph2PCH2P(Ph)C6H4}] 10 and [(Os-3 (CO)(8){mu -SCH(CH3)CH3} {eta (1)-SCN(CH3)CH3} {Ph2PCH2P(Ph)C6H4} (mu -H)] 11 in 75 and 3% yields respectively while with C6H5SH, [(Os-3(CO)(8)(mu- SC6H5)(mu -dppm)(mu -H)] 6 is obtained as the only product in 75 % yield. In both 8 and 10, the thiolato ligand bridges the Os-Os edge which is also bridged by the metallated phenyl group. The neu compounds have been characterized by elemental analyses and spectroscopic methods (IR, H-1 and P-31 NMR). The molecular structures of 7, 8, 9 and 10 are reported as determined by X-ray diffraction studies
