Moderating effect of social support on personal financial constraints and job stress relationship

The aim of this paper is to examine the moderating effect of social support (which may be supervisory, friends, family and relatives) on the relationship of personal financial constraints and job stress relationship. Sample consists of 294 respondents from randomly selected 28 branches of 22 banks located across all major cities of Pakistan. Moderated regression analysis has been used to test the hypothesized relationships. Personal financial constraints enhance job stress and social support moderates this relationship. Job stress increases when an employee faces financial constraints but decreases in the presence of social support. Practical and theoretical implications are drawn. This research is conducted in banking industry, so its results can’t be generalized to other industries. This paper is the first which examines the impact of a non-work related variable, personal financial constraint on job stress along with buffering role of social support. Its findings have great implications for employers for increasing productivity of employees.Job stress, personal financial constraints, social support, moderating, banking, Pakistan

Service quality and customers trust, moderating role of personality traits

Customers’ trust is an inevitable asset for organizations. The long-term relationship of customer-organization depends upon the presence of customers’ trust on the organization. It’s a delicate sense of feeling derived from quality and commitment of the organizations to meet customers’ expectations. The significance of this phenomenon in services industry becomes even more critical where organizations have to know individual as well as contextual factors that influence on customers’ trust. This study tested the impact of different dimensions of perceived service quality on customers’ trust and how this perception varies depending upon the personality disposition in life insurance sector of Pakistan. Using cross sectional research design, the study taped customers’ responses regarding service quality, customers’ trust, and their personality disposition. The sample was obtained from insurance sector in different cities of Pakistan, where 242 customers were participated in the survey Explanatory factor analysis, single mean T-test, correlation and hierarchical multiple regression analyses were used to test proposed hypotheses. The results indicate positive relationship between different dimensions of service quality and customers’ trust. The finding of moderation analysis shows that customer’s personality traits have varied effects on the relationships between dimensions of service quality and customers’ trust. Finally, based on quantitative findings, proposed framework was revised. This study recommends several implications for managers of services industry so that they should develop an effective service design to build long-term customers’ trust in accordance with different personality traits

Surgical management of subclavian and proximal axillary artery injuries

Subclavian and proximal axillary arterial injuries are rare and difficult to manage. Eight patients were managed from January 2008 to December 2018 at The Aga Khan University Hospital, Karachi, Pakistan with mean age of 36.13 ± 14.48 years. All patients had penetrating injuries, from gunshot in 5 (62.5%), bomb blast in 2 (25%), and stab wound in 1 (12.5%) case. Six (75%) patients presented in haemodynamically stable condition. The mean time between the injury and patient presentation was 28 ± 8.39 hours. The injuries were approached via supraclavicular incision in 3 (37.5%) patients, infraclavicular incisions in 2 (25%) patients and median sternotomy in 2 (25%) patients. Three (37.5%) patients had false aneurysm, while 5 (62.5%) had transected artery. Primary repair was performed in 2 (25%) cases, while 6 (75%) patients were treated with interposition graft with polytetrafluoroethylene (PTFE). All patients have salvaged limbs with good functional outcomes

Successful treatment of benign lesions by bis 3- azophenyl-4-hydroxy-6-methyl-pyran-2-one cobalt (II) in albino rats

The study of the effect of bis 3-azophenyl-4-hydroxy-6-methyl-pyran-2-one cobalt (II) as chemotherapeutic agent was undertaken with the intention of studying the effects in 7,12-dimethylbenz[a] anthracene (DMBA) and tetradecanoyl phorbol-13-acetate (TPA) induced chemical carcinogenesis on skin of 5 - 7 weeks old healthy albino rats. The animals were divided into 5 groups (A, B, C, D and E) of twenty each. The rats were treated with carcinogens for 15 weeks and then the curative effect of bis 3-azophenyl-4-hydroxy- 6-methyl-pyran-2-one cobalt (II) was observe. The bis 3-azophenyl-4-hydroxy-6-methyl-pyran-2-one cobalt (II) prevents malignant conversion of  chemically induced benign tumors and did not kill cancer cells but change them to normal cells. It was concluded that if the complex is given in the pre-malignant phase of tumor development, it decreases the risk of malignant transformation.Key words: 7,12-Dimethylbenz[a] anthracene (DMBA), tetradecanoyl phorbol-13-acetate (TPA), complex {bis- 3-azophenyl-4-hydroxy-6-methyl-pyran-2-one cobalt (II)}, skin cancer

Methyl 2-methyl-4-(oxiran-2-ylmeth­oxy)-2H-1,2-benzothia­zine-3-carboxyl­ate 1,1-dioxide

In the title compound, C14H15NO6S, the thia­zine ring adopts a distorted half-chair conformation. The structure displays several cooperative weak inter­molecular C—H⋯O hydrogen-bonding inter­actions, giving rise to a two-dimensional sheet packing motif. The CH2 group in the meth­oxy linker to the oxirane ring, and the CH group in that ring, exhibit twofold positional disorder. The three-membered oxirane ring is twisted approximately perpendicular with respect to thia­zine ring (dihedral angle = 60/86° for the major/minor disorder components). 1,2-Benzothia­zines of this kind have a wide range of biological activities and are mainly used as medicines in the treatment of inflammation and rheumatoid arthritis

Tags: Augmenting Microkernel Messages with Lightweight Metadata

In this work, we propose Tags, an e cient mechanism that augments microkernel interprocess messages with lightweight metadata to enable the development of new, systemwide functionality without requiring the modi cation of application source code. Therefore, the technology is well suited for systems with a large legacy code base and for third-party applications such as phone and tablet applications. As examples, we detailed use cases in areas consisting of mandatory security and runtime veri cation of process interactions. In the area of mandatory security, we use tagging to assess the feasibility of implementing a mandatory integrity propagation model in the microkernel. The process interaction veri cation use case shows the utility of tagging to track and verify interaction history among system components. To demonstrate that tagging is technically feasible and practical, we implemented it in a commercial microkernel and executed multiple sets of standard benchmarks on two di erent computing architectures. The results clearly demonstrate that tagging has only negligible overhead and strong potential for many applications
