Job Strain and Well-being of Teaching Professionals: An Empirical Investigation

The aim of the current study was to examine job strain and well-being in a group of male and female teaching professionals. The main objectives of the current study were to (i) Examine the difference between male teachers with low job strain and female teachers with low job strain on general well-being. (ii) Examine the difference between male teachers with high job strain and female teachers with high job strain on general well-being. (iii) Examine the difference between male teachers with low job strain and male teachers with high job strain on general well-being and (iv) Examine the difference between female teachers with low job strain and female teachers with high job strain on general well-being. A sample of 100 senior secondary teachers were selected from one of the Central Universities at Aligarh City using convenience sampling method of 32 were male and 58 were female teachers. The measures used were PGI Well-being scale (Moudgil et al, 1986) and Job Strain Questionnaire (Singh, 1989). The data were analyzed using descriptive statistics like mean and SD and inferential statistics like t-test. The findings of the current work indicate that mental health of males is better than of their female counterparts. The findings also indicate that high job strain effects the mental health of both the groups and male teachers are influenced more than females on their well-beings. Finally, significant difference was not found between the mean scores of female teachers with low job strain and high job strain on their general well-being. The study has implications for stress management programs for the teachers at senior secondary level to enhance their well-being and specific job related performanc

Impact of zinc uptake on morphology, physiology and yield attributes of wheat in Pakistan

A pot experiment was conducted in the Old Botanical Garden, University of Agriculture Faisalabad, to assess the effect of zinc uptake on morphological, physiological and yield attributes of wheat (Triticum aestivum L.). Two varieties of wheat, i.e. W-141 and W-142, procured from Ayub Agricultural Research Institute (AARI), Faisalabad, Pakistan, were used during this study. The soil used during experiment was field soil from university fields having sandy loam texture. The experiment was laid out in a completely randomized design (CRD) with five treatments and four replicates. Different treatments of zinc were applied on different intervals. After 25 and 35 days of germination, the plants were subjected to three levels of ZnSO4 (0, 400 mgL-1, 600 mgL-1). During the experiment, the harvests were taken after 10 days of intervals for morphological and physiological analysis. After the maturity of plants, final harvest was taken and yield attributes were recorded. Data of various morphological, physiological and yield attributes were statistically analyzed. The results showed that zinc toxicity had adverse effects on the wheat varieties. The variety W-141 was a little bit tolerant to zinc toxicity, as per shown by the results, as compared to W-142, which suffered by the toxicity of zinc. It was also revealed by the results that zinc affects the morphological, physiological and yield attributes of wheat when applied in toxic concentration

Distributed File Sharing and Retrieval Model for Cloud Virtual Environment

Cloud-based storage services are multiplying and are being adapted mostly for data storage. At the same time, many potential problems pertaining to data storage and security are being addressed. This research provides the architecture for splitting user data and the solution in retrieving different data chunks, stored on different cloud storages. By doing this, not only the load on a single server is reduced but security and storage are efficiently used. Data would be stored and retrieved in slices, hence the chances of data forgery are diminishing. File processing will be faster as split parts would be fetched from different clouds, enabling parallel processing

Paraganglioma of the tongue with SDHB gene mutation in a patient with Graves' disease

The authors want to thank Mr. Jose Eduardo Matos (photog-rapher) for his technical assistance.We report a case of an apparently sporadic paraganglioma of the tongue with a germ-line mutation in a female patient with asymptomatic Graves' disease. The tongue is an unusual primary location. Genetic testing is mandatory in all cases. Thyroid gland dysfunction and autoimmune phenomena could be associated with some paragangliomas.S

Evidence of Hot Carrier Extraction in Metal Halide Perovskite Solar Cells

The presence of hot carriers is presented in the operational properties of an (FA,Cs)Pb(I, Br, Cl)3 solar cell at ambient temperatures and under practical solar concentration. At 100 K, clear evidence of hot carriers is observed in both the high energy tail of the photoluminescence spectra and from the appearance of a non-equilibrium photocurrent at higher fluence in light J-V measurements. At room temperature, however, the presence of hot carriers in the emission at elevated laser fluence are shown to compete with a gradual red shift in the PL peak energy as photo induced halide segregation begins to occur at higher lattice temperature. The effects of thermionic emission of hot carriers and the presence of a non-equilibrium carrier distribution are also shown to be distinct from simple lattice heating. This results in large unsaturated photocurrents at high powers as the Fermi distribution exceeds that of the heterointerface controlling carrier transport and rectification

Solution-Printed Organic Semiconductor Blends Exhibiting Transport Properties on Par with Single Crystals

Solution-printed organic semiconductors have emerged in recent years as promising contenders for roll-to-roll manufacturing of electronic and optoelectronic circuits. The stringent performance requirements for organic thin-film transistors (OTFTs) in terms of carrier mobility, switching speed, turn-on voltage and uniformity over large areas require performance currently achieved by organic single-crystal devices, but these suffer from scale-up challenges. Here we present a new method based on blade coating of a blend of conjugated small molecules and amorphous insulating polymers to produce OTFTs with consistently excellent performance characteristics (carrier mobility as high as 6.7 cm2V−1s−1, low threshold voltages of \u3c1V and low sub threshold swings \u3c0.5Vdec−1). Our findings demonstrate that careful control over phase separation and crystallization can yield solution-printed polycrystalline organic semiconductor films with transport properties and other figures of merit on par with their single-crystal counterparts

Estimation in a Competing Risks Proportional Hazards Model Under Length-biased Sampling With Censoring

International audienceWhat population does the sample represent? The answer to this question is of crucial importance when estimating a survivor function in duration studies. As is well-known, in a stationary population, survival data obtained from a cross-sectional sample taken from the population at time $t_0$ represents not the target density $f(t)$ but its length-biased version proportional to $tf(t)$, for $t>0$. The problem of estimating survivor function from such length-biased samples becomes more complex, and interesting, in presence of competing risks and censoring. This paper lays out a sampling scheme related to a mixed Poisson process and develops nonparametric estimators of the survivor function of the target population assuming that the two independent competing risks have proportional hazards. Two cases are considered: with and without independent consoring before length biased sampling. In each case, the weak convergence of the process generated by the proposed estimator is proved. A well-known study of the duration in power for political leaders is used to illustrate our results. Finally, a simulation study is carried out in order to assess the finite sample behaviour of our estimators
