Career effectiveness and its determinants

Study of careers has become an important aspect in the fast changing organizational context. It has come to be increasingly recognized at present, that career management is the responsibility of both the individual as well as the organization. This empirical study tries to understand the important elements of individual and organizational career practices that affect an employee’s career effectiveness. Most of the previous studies have used the objective terms of career success such as remuneration and position as the criterion variable. But since career outcome expectations vary across individuals and also since the concept of career itself has evolved over time, it was decided to use a more comprehensive concept of career outcome namely career effectiveness as the outcome variable. Career effectiveness as defined by Hall (2002) has both long-term orientation such as identity and adaptability as well as short-term orientation such as career attitudes and performance. Further both behavioral aspects such as performance and adaptability and individual subjective aspects such as identity and attitudes make it a more comprehensive way of assessing career outcome. The results of this research study indicate that individual determinants such as career planning and knowledge of organizational politics and organizational level determinants such as training and development support, quality of performance feedback and supervisory support explain significant variances in the determination of employee career effectiveness.

Proper Motion of the Faint Star near KIC 8462852 (Boyajian's Star) - Not a Binary System

A faint star located 2 arcsec from KIC 8462852 was discovered in Keck 10 m adaptive optics imaging in the $JHK$ near-infrared (NIR) in 2014 by Boyajian et al. (2016). The closeness of the star to KIC 8462852 suggested the two could constitute a binary, which might have implications for the cause of the brightness dips seen by {\it Kepler} (Boyajian et al. (2016) and in ground-based optical studies Boyajian et al. (2018). Here, NIR imaging in 2017 using the Mimir instrument resolved the pair and enabled measuring their separation. The faint star had moved $67 \pm 7$ milliarcsec (mas) relative to KIC 8462852 since 2014. The relative proper motion of the faint star is $23.9 \pm 2.6$ mas yr$^{-1}$, for a tangential velocity of $45 \pm 5$ km s$^{-1}$ if it is at the same 390 pc distance as KIC 8462852. Circular velocity at the 750 AU current projected separation is $1.5$ km s$^{-1}$, hence the star pair cannot be bound.Comment: 10 pages, 2 figure

The number of privately treated tuberculosis cases in India: an estimation from drug sales data

Background Understanding the amount of tuberculosis managed by the private sector in India is crucial to understanding the true burden of the disease in the country, and thus globally. In the absence of quality surveillance data on privately treated patients, commercial drug sales data offer an empirical foundation for disease burden estimation. Methods We used a large, nationally representative commercial dataset on sales of 189 anti-tuberculosis products available in India to calculate the amount of anti-tuberculosis treatment in the private sector in 2013–14. We corrected estimates using validation studies that audited prescriptions against tuberculosis diagnosis, and estimated uncertainty using Monte Carlo simulation. To address implications for numbers of patients with tuberculosis, we explored varying assumptions for average duration of tuberculosis treatment and accuracy of private diagnosis. Findings There were 17·793 million patient-months (95% credible interval 16·709 million to 19·841 million) of anti-tuberculosis treatment in the private sector in 2014, twice as many as the public sector. If 40–60% of private-sector tuberculosis diagnoses are correct, and if private-sector tuberculosis treatment lasts on average 2–6 months, this implies that 1·19–5·34 million tuberculosis cases were treated in the private sector in 2014 alone. The midpoint of these ranges yields an estimate of 2·2 million cases, two to three times higher than currently assumed. Interpretation India's private sector is treating an enormous number of patients for tuberculosis, appreciably higher than has been previously recognised. Accordingly, there is a re-doubled need to address this burden and to strengthen surveillance. Tuberculosis burden estimates in India and worldwide require revision

AN INTANGIBLE LEARNING OF WORK LIFE BALANCE WITH EMPLOYS

Changes within the civil, legislative and monetary goods of societies experience swayed and attain persuade the two the character of hiring and its affair to a woman out of doors activities. Work living assess has to turn into a hot subject matter in recent times fuelled partly by unstable trends in ladies' civil acts. Whilst labour barter attendance has elevated for ladies of every age, women folk end assume the most honesty for organizing and venture overdue worrying handle. In India, it's far universal which fiscal activities are completely the birthright of males even though indigenous go, impregnation and youngster rearing are the only occupations of females. Historically, womenfolk in India haven't enjoyed a very good dignity in place settings if in organizational or operational tasks. Since times of yore, ladies happen to be taxed upon the act of all kinds throughout their lives. From copy to all house chores and outdoors, their business as cater is critical, strange and difficult. But they're discriminated and abused throughout. The Services Sector constitutes a substantial part of your Indian deduction the two when it comes to hiring likely and its increase in the interstate source of revenue. The Sector covers a variety of activities of the such a lot sophisticated inside the field of Information and Communication Technology to clear-cut products and services pursued separately unofficial district goers, as an example, produce sellers, hawkers, wagon pullers, etc in association with stable developing emergent nations, India is weird for the act of your service part

Extraction and Purification of Organophosphorus hydrolase Enzyme from Soil Microorganism Pseudomonas diminuta

Synthetic organophosphorus compounds are highly toxic hence, widely used as pesticides, insecticides and chemical warfare agents. Organophosphorus hydrolase (OPH) is an organophosphotriester hydrolyzing enzyme; effectively hydrolyze a range of organophosphate esters. The objective of the present study was extraction and purification of OPH enzyme from Pseudomonas diminuta bacteria (soil microorganism) and to study kinetic properties of the purified enzyme. Enzyme was extracted and purified from bacteria by ammonium sulphate precipitation and ion exchange chromatography. Purity of an enzyme was determined by sodium dodecyl sulphate-polyacryamide gel electrophoresis (SDS-PAGE). Purified OPH enzyme specific activity was found to be 27.7 fold of 32.8U/mg protein, molecular weight of 72 Kda and it is a homodimer since it has shown a single band in SDS-PAGE separation. Maximum activity of the free OPH enzyme was found at Optimum pH 7.5 and temperature 35oC with the incubation time of 10 min. Michaelis constant (Km) and maximum velocity (Vmax) values of free OPH enzyme for methyl parathion as substrate was found to be 286.2μM and 2.5 μM/min respectively

Influence of zeolite on heavy metal immobilization in municipal solid waste compost contaminated soil

The application of Municipal solid waste as compost (MSWC) in agricultural fields has become one of the most common practices. Besides its benefits, it poses some harmful effects on soil, as it increases the heavy metal content in MSWC of the soil. It is necessary to find a way to reduce the bioavailability of heavy metals in MSWC  before its application into the soil. This study aimed at exploring the efficiency of zeolite as an immobilizer to dwindle heavy metal bioavailability. An incubation experiment was conducted wherein the soil samples were artificially spiked with different rates of MSWC (0, 5, and 10 t ha-1). The zeolite was added to the spiked soil at 5 different levels, namely 0, 5, 10, 15, and 20 %, and their effect on bioavailable heavy metal status was observed during different incubation intervals (0, 15. 30, 60, 90, and 120 days). Results unveiled that applying 10% zeolite significantly (P<0.05) reduced the bioavailability of lead (Pb) and nickel (Ni)  to Below the detectable limit (Bdl) in all soil samples. Furthermore, the organic carbon status of soil was also enriched by MSWC and 10% zeolite application. The soil pH slightly increased (7.39) with applying 10% zeolite resulting in the immobilization of heavy metals. Hence, 10% zeolite application was one of the most effective immobilizers in eliminating the bioavailability of heavy metals. Therefore, it can be concluded that mixing zeolite with MSWC before applying it to crop fields can reduce the heavy metal overload in soil. Hence, this study highlights the potential of zeolite as an effective choice in dwindling the soil's bioavailability of heavy metal content

Effect of high temperature heat treatments on the quality factor of a large-grain superconducting radio-frequency niobium cavity

Large-grain Nb has become a viable alternative to fine-grain Nb for the fabrication of superconducting radio-frequency cavities. In this contribution we report the results from a heat treatment study of a large-grain 1.5 GHz single-cell cavity made of "medium purity" Nb. The baseline surface preparation prior to heat treatment consisted of standard buffered chemical polishing. The heat treatment in the range 800 - 1400 C was done in a newly designed vacuum induction furnace. Q0 values of the order of 2x1010 at 2.0 K and peak surface magnetic field (Bp) of 90 mT were achieved reproducibly. A Q0-value of (5+-1)1010 at 2.0 K and Bp = 90 mT was obtained after heat treatment at 1400 C. This is the highest value ever reported at this temperature, frequency and field. Samples heat treated with the cavity at 1400 C were analyzed by secondary ion mass spectrometry, secondary electron microscopy, energy dispersive X-ray, point contact tunneling and X-ray diffraction and revealed a complex surface composition which includes titanium oxide, increased carbon and nitrogen content but reduced hydrogen concentration compared to a non heat-treated sample
