Job Satisfaction and Organizational Commitment of University Teachers in Public Sector of Pakistan

Study Objectives: The purpose of this investigation was to determine the impact of teachers’ satisfaction with job dimensions on perceived organizational commitment in public sector universities of Pakistan. In addition, the study aimed at exploring to what extent these teachers are committed to their universities and satisfied with different dimensions to their job. Research Design/Methodology: A survey-based descriptive research design was used. The study was carried on teaching faculty working in two public sector universities of Pakistan. About 650 survey questionnaires were distributed in October, 2009 by employing diverse modes of communication such as email, in person and post. Multiple follow ups yielded 331 statistically usable questionnaires. Stepwise regression analysis and one sample t-tests were used to confirming the research hypotheses. Results: The findings of the study indicated that the satisfaction with work-itself, quality of supervision and pay satisfaction had significant positive influence on organizational commitment of faculty members. They had high degree of organizational commitment and satisfaction with work-itself, supervision, salary, coworkers and opportunities for promotion. Research limitations/implications: The focus of the study was teachers working at public sectors universities in Pakistan only. Self-reported measures were used to measure job satisfaction and organizational commitment. Since respondents were from two public sector universities only so the findings cannot be generalized to faculty members of public sector universities in Pakistan. Practical implications: Considering the importance of university teachers’ organizational commitment and their effects on effectiveness of the universities, policy makers and academic administrators should take necessary
Job satisfaction and organizational commitment in teachers of the Peruvian Amazon

This research sought to establish the relationship between job satisfaction and organizational commitment in teachers of regular basic education in the Peruvian Amazon. The research had a quantitative approach and its design was non-experimental of a correlational type. The sample consisted of 185 teachers to whom the Labor Satisfaction Scale and the Organizational Commitment Questionnaire were applied, instruments with the required validity and reliability. The findings indicate that teachers' level of job satisfaction and organizational commitment is regular and the existence of a direct and significant relationship between job satisfaction and organizational commitment was determined (rs= 0.539; p= 0.000 <0.05). It is concluded that the more satisfied teachers are in their work centers, the greater their level of commitment to the institution.
The Ses Health Gradient on Both Sides of the Atlantic

In this paper we investigate the size of health differences that exist among men in England and the United States and how those differences vary by Socio Economic Status (SES) in both countries. Across a wide variety of diagnosed diseases, average health status among mature men is much worse in America compared to England. A steep negative health gradient exists for men in both countries. This social health gradient is present whether education, income, or financial wealth is used as the marker of SES and, in addition, appears to be steeper in the United States. These conclusions are maintained even after controlling for a standard set of behavioral risk factors such as smoking, drinking, and obesity and are equally true using either biological measures of disease or individual self reports. In contrast to these disease based measures of health, the health of American men appears to be superior to the health of English men when self reported subjective general health status is used as the measure of health status. This apparent contradiction does not result from differences in co morbidity, emotional health, or ability to function, all of which still point to mature American men being less healthy than their English counterparts. Finally, we present preliminary data that indicate that feedbacks from new health events to household income are also one of the reasons that underlie the strength of the income gradient in health.
Income inequality and self-rated health status: Evidence from the european community household panel

We examine the effect of income inequality on individualś self-rated health status in a pooled sample of 11 countries, using longitudinal data from the European Community Household Panel survey. Taking advantage of the longitudinal and cross-national nature of our data, and carefully modeling the self-reported health information, we avoid several of the pitfalls suffered by earlier studies on this topic. We calculate income inequality indices measured at two standard levels of geography (NUTS-0 and NUTS-1) and find consistent evidence that income inequality is negatively related to self-rated health status in the European Union for both men and women, particularly when measured at national level. However, despite its statistical significance, the magnitude of the impact of inequality on health is very small.
Do the Rich Save More in Canada

This paper is an attempt to answer the long standing question of whether households with higher lifetime income save a larger fraction of their income. The major difficulty in empirically assessing the relationship between lifetime incomes and saving rates is to construct a credible proxy for lifetime income. The Canadian Family Expenditure Survey (FAMEX) provides us with both unusually good data on savings rates and potential instruments with which we can construct reliable lifetime income proxies. Our empirical analysis suggests that the estimated relationship between saving rates and lifetime incomes is sensitive to the instrument used to proxy lifetime income. Nevertheless, our preferred estimates indicate that, except for poorest households (who simply do not save), saving rates do not differ substantially across lifetime income groups.
SOCIAL AND ECONOMIC DIMENSIONS OF AN AGING POPULATION

A molten metal gas-atomizing spray-depositing apparatus employs an asymmetrical gas-atomizing device for generating one-sided shear forces for breaking-up and atomizing a stream of molten metal into metal particles in a divergent spray pattern of higher mass density at an upstream leading peripheral portion of the spray pattern, relative to the direction of movement of a substrate, than either of a center region or downstream trailing peripheral region of the pattern.
Graph modelling without graphs

The paper is a contribution to developing a new apparatus of composition of probability measures on finite spaces enabling to define structures equivalent to graph models without exceeding the framework of probability theory. It is based on the idea that multidimensional measures can be composed from sets (or sometimes sequences) of low-dimensional measures by application of specific operators of composition. In the preceding paper [3] we dealt with structures equivalent to Bayesian networks (so called perfect sequences) whereas the present paper introduces structures equivalent to decomposable models - commutable sets of low-dimensional measures.
Entry Costs and Stock Market Participation Over the Life Cycle 1

Several explanations for the observed limited stock market participation have been offered in the literature. One of the most promising is the presence of market frictions mostly in the form of fixed entry and/or transaction costs. Empirical studies point to a significant structural (state) dependence in the the stock market entry decision, which is consistent with costs of this type. However, the magnitude of these costs is not yet known. This paper focuses on fixed stock market entry costs. I set up a structural estimation procedure which involves solving and simulating a life cycle intertemporal portfolio choice model augmented with a fixed stock market entry cost. Important features of household portfolio data (from the PSID) are matched to their simulated counterparts. Utilizing a Simulated Minimum Distance estimator, I estimate the coefficient of relative risk aversion, the discount factor and the stock market entry cost. Given the equity premium and the calibrated income process, I estimate a one-time entry cost of approximately 2 percent of the permanent component of the annual labor income. My estimated model matches the zero median holding as well as the hump-shaped age-participation profile observed in the data.
Insufficient amounts and inadequate distribution of dietary protein intake in apparently healthy older adults in a developing country: implications for dietary strategies to prevent sarcopenia

Background: Both low dietary protein intake and inadequate distribution of protein over the three mealtimes have been reported in older Caucasian adults, but the association between protein intake at each meal and muscle mass has not been studied. The purpose of this study was to evaluate dietary protein intake and distribution by mealtimes, and to explore their association with appendicular skeletal muscle mass in apparently healthy older adults
Novel approximate UTD ray solution for the radiation and scattering by antennas near a planar material junction on PEC ground plane

Abstract A novel approximate uniform geometrical theory of diffraction (UTD) for analyzing an electromagnetic wave diffracted by a planar material junction on PEC ground plane has been developed in this research. The proposed UTD solution is based on an ansatz obtained from the Weiner–Hopf (W–H) solution by approximating the W–H split functions. This makes the proposed UTD solution to be a relatively simple and closed form expression. Additionally, the proposed UTD solution can deal with both a planar material junction on PEC ground plane and a two-part problem with any types of wave illumination such as a plane wave, a cylindrical wave, and a spherical wave. The accuracy of the proposed UTD solution is compared with the W–H solution and finite different time domain (FDTD) which provides very good agreement. The proposed UTD solution has very small numerical errors. However, the accuracy of the proposed UTD solution is good enough for engineering applications.
A retrospective randomized study to compare the energy delivered using CDe with different techniques and OZil ® settings by different surgeons in phacoemulsification

The supracapsular phaco technique and burst mode is known for efficiency and surgery is faster compared with the old phaco unit. In this study, we found that supracapsular phaco with burst mode had the least CDE in both cataract and nuclear sclerosis cataract with the new Infiniti unit. We suggest that CDE can be used as one of the references to modify technique and setting to improve outcome for surgeons, especially for new surgeons.
Biological targets in the treatment of rheumatoid arthritis : a comprehensive review of current and in-development biological disease modifying anti-rheumatic drugs

Correspondence: Petros efthimiou Chief, rheumatology Division, Lincoln Medical and Mental Health Center, 234 e. 149th Street, NY, NY 10451, USA Tel +1 718 579 6131 Fax +1 718 579 4836 email petrosefthimiou@gmail.com Abstract: Enhanced understanding of the rheumatoid arthritis (RA) pathophysiology and the role of cytokines has enabled the development of innovative biological agents in the last 10 years that target specific parts of the immune response. Failure to achieve adequate response with traditional disease modifying anti-rheumatic drugs (DMARDs) and increasing evidence of ongoing radiographic deterioration of the affected joints despite seemingly clinical response were essential stimuli for the development of biologics. The current and upcoming biological agents are primarily aimed at neutralizing circulating and cell-bound pro-inflammatory cytokines, interfering in the interaction of antigen-presenting and T-lymphocytes, eliminating circulating B-lymphocytes or by interfering with the intracellular signaling mechanisms of immuno-competent cells that lead to inflammation. These agents have improved the currently available treatments due to greater efficacy, fast action and greater tolerability. However, use of these agents has also been associated with significant, although rare, adverse events and considerable cost. Therefore, these agents should be used with caution by experienced clinicians. The present work aims to provide a global and updated review of the current and in-development biological DMARDs for the treatment of RA.
Efficacy of patterned scan laser in treatment of macular edema and retinal neovascularization

Correspondence: Levent Akduman Department of Ophthalmology, saint Louis University eye institute, 1755 south grand Blvd., st. Louis, Missouri 63104, UsA Tel +1 314-256-3200 email lakduman@pol.net Purpose: To analyze the benefits, efficacy, and complications of the PASCAL photocoagulation laser system (OptiMedica, Santa Clara, CA, USA) in patients treated at our institution. Methods: We conducted a retrospective chart review of 19 patients (28 eyes) who underwent laser treatment using the PASCAL photocoagulation system from November 2006 to November 2007. These 28 eyes were divided into two groups; group 1 eyes underwent macular grid laser and group 2 eyes underwent panretinal photocoagulation. Treatment was performed for macular edema or for iris or retinal neovascularization. Outcomes measured included best-corrected visual acuity (BCVA), efficacy of laser treatment, complications, duration of the procedure, and pain perception, which were noted in the charts for panretinal treatments. Results: Follow-up was 5.9 ± 2.6 months for group 1 and 5.9 ± 4.0 months for group 2. In group 1, 9/28 eyes required a second treatment for remaining edema. BCVA was stable or better in 66% (14/21) and average central foveal thickness on ocular coherence tomography improved in 71% (15/21). Time to completion for a number of laser patterns for grid photocoagulation was felt to be too long for completing the total pattern safely, although we have not noted any related complications. In group 2, the neovascularization regressed at least partially in 3/7 patients. Patient-reported pain perception was 3.6 on a scale of 1 to 10 for group 2. Occasional hemorrhages occurred secondary to irregular laser uptake at different spots in the patterns. We observed no visual outcome consequences because of these hemorrhages during follow-up. Conclusions: Retinal photocoagulation by the PASCAL laser has comparable efficacy to historical results with conventional retinal photocoagulation in short-term follow-up. PASCAL photocoagulation can be performed quicker with less discomfort for patients.
Susac’s syndrome: Leptomeningeal enhancement on 3D FLAIR MRI

Background: Contrast-enhanced (ce) fluid-attenuated inversion recovery magnetic resonance imaging (FLAIR MRI) has recently been shown to identify leptomeningeal pathology in multiple sclerosis. Objective: To demonstrate leptomeningeal enhancement on three-dimensional (3D) FLAIR in a case of Susac’s syndrome. Methods: Leptomeningeal enhancement was correlated with clinical activity over 20 months and compared to retinal fluorescein angiography. Results: The size, number, and location of leptomeningeal enhancement varied over time and generally correlated with symptom severity. The appearance was remarkably similar to that of retinal vasculopathy. Conclusion: Ce 3D FLAIR may aid in diagnosis and understanding of pathophysiology in Susac’s syndrome and may serve as a biomarker for disease activity.
University of Huddersfield Repository Investigation of stress relaxation in hydrated gluten networks using spectral analysis

Gluten and its protein fractions were isolated from wheat flour. Stress relaxation in hydrated gluten, its protein fractions and varying percentage mixtures of the components were investigated by means of rheometry and confocal laser scanning microscopy. Stress relaxation was carried out over a period of 30 min at 20 °C for all samples under investigation. Samples exhibited relaxation modulus G(t) ranging from 1 to about 1000 Pa with the gliadin fraction showing almost full decay. MATLAB with the combination of regularization algorithms were used to generate L-curves and calculate the relaxation spectra of the samples. Stress relaxation spectra identified five dominant relaxation modes with baseline resolution. Stress relaxation is somewhat independent of compositional differences, although, confocal microscopy showed the influence of protein composition on the morphology of the networks. Therefore, morphology and relaxation dynamics seem to be controlled by independent mechanisms for gluten networks. These findings provide a fundamental understanding of gluten dynamics and may allow controlling the industrial performance of flours and engineering novel dough formulations.

 H∞ Control of Discrete‐time Singular Systems via Integral Sliding Surface

In this paper, the sliding mode control for a class of uncertain discrete‐time singular system with H∞ performance constraint is studied. By taking the singular matrix E into consideration, a new type of integral sliding mode surface is firstly introduced, based on which a sufficient condition is derived to guarantee the sliding mode dynamics admissible with a given γ‐level disturbance attenuation of the unmatched disturbance. A controller law is also given to keep the system trajectory staying in a neighborhood of the ideal sliding surface. Finally, a numerical example is given to show the effectiveness of the proposed approach.
Numerical Simulation Of An Over-Expanded Supersonic Nozzle Flow

Flaring in oil and gas production is the controlled burning of unwanted exhaust gases to enhance safety. Obtaining complete combustion and thus eliminating or reducing smoke is critical to meet increasingly strict environmental regulations. To improve flare combustion, gas flares are equipped with air nozzles that introduce extra oxygen and improve mixing in the combustion zone. These nozzles are operated in the subsonic, sonic, or supersonic regimes. In this paper we are concerned with turbulence modeling of the jet flow exiting from a particular convergent-divergent nozzle used in flare systems. The Realizable k − ε and SST k − ω models are used to study the compressible flow within that specific nozzle, which has an exit diameter of 3.38 mm and has convergent and divergent sections that are connected via a throat section with a finite length and constant diameter. The velocity profiles and turbulent kinetic energy predicted by both turbulence models, in the vicinity of the nozzle outlet and along the symmetry axis of the nozzle, are compared for nozzle pressure ratios in the range 1.18 ≤ NPR ≤ 1.78 . It is shown that for Ma ≤ 1, both turbulence models predict nearly identical flow evolution along the nozzle. When the flow becomes supersonic, the shock surface, and consequently nozzle outlet velocity profiles, predicted by the SST k − ω model deviates slightly from the other model. The differences, however, become negligible a couple of diameters downstream of the nozzle outlet. Computed entrainment rate coefficients vary slightly when changing the turbulence model, and this difference remains insignificant with increasing downstream distance.
Is severe perineal damage increased in women with prior anal sphincter injury?

Objective. There is conflicting data in the literature regarding the risk of obstetric anal sphincter laceration in patients with a prior laceration. This retrospective chart review seeks to examine the risk of recurrence of obstetric anal sphincter lacerations. Methods. Patients who sustained anal sphincter laceration at delivery during a 13-year time period from January 1991 to December 2003 were identified from the medical records database at Temple University Hospital. All subsequent deliveries in this group of patients were extracted from the database. Chart review was performed on all subsequent deliveries with specific attention to demographic factors such as age, race, parity, etc., maternal weight, fetal weight, presence of maternal diabetes, and labor characteristics such as induction or augmentation of labor, instrumentation at delivery (vacuum or forceps), use of episiotomy, and degree of perineal laceration. Results. There were 23 451 vaginal deliveries at Temple University Hospital between January 1, 1991 and December 31, 2003. Anal sphincter laceration was noted in 778 subjects. Subsequent deliveries among the group of patients with prior sphincter tears numbered 271. Six (2.4%) patients had recurrence of anal sphincter lacerations, and five of them were third degree lacerations. The rate of recurrent lacerations was not significantly different from the rate of initial lacerations (2.4% vs. 3.3%; odds ratio 0.72, 95% confidence interval 0.33–1.59; p = 0.4). Women who sustained recurrent lacerations were older, more obese (mean weight 92 kg vs. 82 kg), had larger babies (3506 g vs. 3227 g), and were more likely to have episiotomies (66.7% vs. 7%) or instrumental deliveries (33.3 vs. 6.5%). Conclusion. Prior anal sphincter laceration does not result in an increased rate of recurrence. Operative vaginal delivery particularly with episiotomy is a risk factor for both initial and recurrent laceration.
