The Relationship between Work Values, Affective Commitment, Emotional Intelligence, and Employee Engagement: A Moderated Mediation Model

Affective commitment is considered to be the most critical element of organizational commitment because of its impact in reducing employee turnover, absenteeism and in enhancing the effectiveness of the organization. Because of the nature of the job, emotional intelligence is also a significant trait for employees working in banks. Based on a sample of 354 employees selected from the banking sector of Pakistan, this study revealed that work values had a significant impact on affective commitment. The findings of this study also confirmed the mediation of emotional intelligence and moderation of employee engagement between the relationship of work values and affective commitment among banking professionals of Pakistan. This study also provides practical foresight for the HRM professionals to enhance retention of effective manpower

The initial abundance and distribution of 92Nb in the Solar System

Niobium-92 is an extinct proton-rich nuclide, which decays to 92Zr with a half-life of 37 Ma. This radionuclide potentially offers a unique opportunity to determine the timescales of early Solar System processes and the site(s) of nucleosynthesis for p-nuclei, once its initial abundance and distribution in the Solar System are well established. Here we present internal Nb-Zr isochrons for three basaltic achondrites with known U-Pb ages: the angrite NWA 4590, the eucrite Agoult, and the ungrouped achondrite Ibitira. Our results show that the relative Nb-Zr isochron ages of the three meteorites are consistent with the time intervals obtained from the Pb-Pb chronometer for pyroxene and plagioclase, indicating that 92Nb was homogeneously distributed among their source regions. The Nb-Zr and Pb-Pb data for NWA 4590 yield the most reliable and precise reference point for anchoring the Nb-Zr chronometer to the absolute timescale: an initial 92Nb/93Nb ratio of $(1.4 \pm 0.5) \times 10^{-5}$ at $4557.93 \pm 0.36$ Ma, which corresponds to a 92Nb/93Nb ratio of $(1.7 \pm 0.6) \times 10^{-5}$ at the time of the Solar System formation. On the basis of this new initial ratio, we demonstrate the capability of the Nb-Zr chronometer to date early Solar System objects including troilite and rutile, such as iron and stony-iron meteorites. Furthermore, we estimate a nucleosynthetic production ratio of 92Nb to the p-nucleus 92Mo between 0.0015 and 0.035. This production ratio, together with the solar abundances of other p-nuclei with similar masses, can be best explained if these light p-nuclei were primarily synthesized by photodisintegration reactions in Type Ia supernovae.Comment: Accepted to Earth and Planetary Science Letter

Peripheral Neuropathy in Newly Diagnosed Cases of Type II Diabetes Mellitus

Objective: Diabetes mellitus linked to severe macrovascular and the microvescular complications. Diabetic peripheral neuropathy is the challenging complication of the diabetes mellitus, which is linked to the morbidity, mortality, and big economic burden. We determined the frequency of peripheral neuropathy in newly diagnosed cases of type II diabetes mellitus.Materials & Methods: The current descriptive Cross Sectional study took place in Services Institute of Medical Sciences, Lahore, From June 2014 to January 2015. All the patients, those were newly diagnosed with diabetes mellitus, aged 30-60 years and both genders were included. Detailed history regarding diabetes was taken. Patients underwent for the evaluation of peripheral neuropathy by taking physical examination, previous history and vibration perception test. All the data was recorded in the Proforma.Results: Total 150 cases were studied, out of them, 42.67% were aged 30-45 years while 57.33% were in the age range of 46-60 years and their overall mean age was 46.35 ± 9.52 years. Males were 54.0% and females were 46.0%. Frequency of peripheral neuropathy for newly diagnosed type II diabetic subjects was noted 20.67%, with insignificant association of age and gender.Conclusion: It was concluded that the peripheral neuropathy was 20.67% among patients newly diagnosed with diabetes mellitus

Investigation of Toxic Metals in the Tobacco of Pakistani Cigarettes Using Proton-Induced X-Ray Emission

A particle-induced X-ray emission (PIXE) study has been carried out to find out whether available local and imported cigarette brands in Pakistan have elevated concentration of metals or not. The results are compared within the brands examined in this study and with the results of related studies in literature. A sum of 19 different cigarette brands was purchased randomly from different Pakistani markets which included local and imported brands. The concentration of elements like Cd, Pb, Zn, Fe, Mn, Ni, Cu, and Co was investigated. Results showed that different cigarette brands have different metal contents. The mean concentration of the heavy metals is Cd—4.92 μg/g, Co—0.12 μg/g, Cu—0.97 μg/g, Ni—0.13 μg/g, Pb—1.02 μg/g, and Zn—12.91 μg/g per dry weight. Compared with the reported results of other international studies, Pakistani cigarettes are observed to have lower heavy metal contents except for cadmium which was higher. This study will provide adequate data for all concerned departments. This study will also create awareness among people about the toxicity of metals present in tobacco of cigarettes
