Business Process Re-engineering: A Panacea for Reducing Operational Cost in Service Organizations

Organizations in today’s business environment struggle on how to reduce operation cost in order to set prices that can be afforded by many customers while obtaining reasonable profit.  In order to reduce Operational Cost, service organizations have been working hard to identify techniques that facilitate business processes improvement for reduced Operational Cost. In so doing, the global literature indicates that service organizations adopt Business Process Re-engineering technique as a panacea of reducing Operational Cost. Despite a documented potentiality of Business Process Re-engineering technique, there are mixed empirical results, findings and conclusions regarding the effect of Business Process Re-engineering on Operational Cost. Therefore, this paper aimed at assessing and explaining effects of BPR on Operational Cost.The study used cross-sectional survey design to investigate the effect of BPR on Operational Cost. Intensive literature review enabled the construction of structural measurement model, formulation of testable hypotheses and operationalization of constructs. In order to test the model and hypotheses, data were collected from ninety five (95) service organizations in Tanzania. Results of the study reveal that BPR and delivering speed have no direct effects on Operational Cost; they indirectly affect Operational Cost through the mediations of service quality. Therefore, BPR influences first both service quality and delivery speed in affecting Operational Cost of service organizations. It is now recommended that service organizations should use Business Process Re-engineering as panacea of reducing Operational Cost

Business process re-engineering: the technique to improve delivering speed of service industry in Tanzania

Problem statement: Delivering speed is very critical in today’s business environment. In most cases, service organizations and customers are sensitive to time spent at delivering or receiving a service. Therefore, service organizations must change in order to meet this challenge. Overtime, service organizations have worked hard to identify techniques that enhance service delivering speed for improved performance. Business process re-engineering is one of such techniques that improves business processes; including delivering speed. However, despite documented advantages, most organizations are reluctant to adopt the technique. Purpose: The paper aims at determining the effect of business process re-engineering on delivering speed; enabling organizations to appreciate the performance improvement that is associated with the technique. Methodology: The study used cross-sectional survey design to investigate the effect of BPR on delivering speed. In order to undertake the study, intensive literature review was undertaken to operationalize the constructs and to formulate the hypothesis which was tested after the field work. In total ninety five (95) service organizations participated in the study. Results: From the study, it is revealed that BPR significantly and positively improves delivering speed of service organizations. Conclusion: For improved delivering speed, service organizations should adopt BPR technique to improve business processes for provision of delighting services to customers

Endocrine and molecular investigations in a cohort of 25 adolescent males with prominent/persistent pubertal gynecomastia

Pubertal gynecomastia is a common condition observed in up to 65% of adolescent males. It is usually idiopathic and tends to regress within 1–2 years. In this descriptive cross-sectional study, we investigated 25 adolescent males with prominent (>B3) and/or persistent (>2 years) pubertal gynecomastia (P/PPG) to determine whether a hormonal/genetic defect might underline this condition. Endocrine investigation revealed the absence of hormonal disturbance for 18 boys (72%). Three patients presented Klinefelter syndrome and three a partial androgen insensitivity syndrome (PAIS) as a result of p.Ala646Asp and p.Ala45Gly mutations of the androgen receptor gene. The last patient showed a 17α-hydroxylase/17,20-lyase deficiency as a result of a compound heterozygous mutation of the CYP17A1 gene leading to p.Pro35Thr(P35T) and p.Arg239Stop(R239X) in the P450c17 protein. Enzymatic activity was analyzed: the mutant protein bearing the premature stop codon R239X showed a complete loss of 17α-hydroxylase and 17,20-lyase activity. The mutant P35T seemed to retain 15–20% of 17α-hydroxylase and about 8–10% of 17,20-lyase activity. This work demonstrates that P/PPG had an endocrine/genetic cause in 28% of our cases. PAIS may be expressed only by isolated gynecomastia as well as by 17α-hydroxylase/17,20-lyase deficiency. Isolated P/PPG is not always a ‘physiological’ condition and should thus be investigated through adequate endocrine and genetic investigations, even though larger studies are needed to better determine the real prevalence of genetic defects in such patients

Topics included HIV and global health, HIV and hepatitis cure, the microbiome and immunotherapies, clinical research and methodology, as well as chemsex, pre-exposure prophylaxis, sexually transmitted infections and emerging infectious diseases. Novel areas of research were also described, such as electronic technology in order to improve HIV management, and the expert patient

Diffusion and jump-length distribution in liquid and amorphous Cu33_{33}Zr67_{67}

Using molecular dynamics simulation, we calculate the distribution of atomic jum ps in Cu$_{33}$Zr$_{67}$ in the liquid and glassy states. In both states the distribution of jump lengths can be described by a temperature independent exponential of the length and an effective activation energy plus a contribution of elastic displacements at short distances. Upon cooling the contribution of shorter jumps dominates. No indication of an enhanced probability to jump over a nearest neighbor distance was found. We find a smooth transition from flow in the liquid to jumps in the g lass. The correlation factor of the diffusion constant decreases with decreasing temperature, causing a drop of diffusion below the Arrhenius value, despite an apparent Arrhenius law for the jump probability

Education and older adults at the University of the Third Age

This article reports a critical analysis of older adult education in Malta. In educational gerontology, a critical perspective demands the exposure of how relations of power and inequality, in their myriad forms, combinations, and complexities, are manifest in late-life learning initiatives. Fieldwork conducted at the University of the Third Age (UTA) in Malta uncovered the political nature of elder-learning, especially with respect to three intersecting lines of inequality - namely, positive aging, elitism, and gender. A cautionary note is, therefore, warranted at the dominant positive interpretations of UTAs since late-life learning, as any other education activity, is not politically neutral.peer-reviewe

Effect of strain on surface diffusion in semiconductor heteroepitaxy

We present a first-principles analysis of the strain renormalization of the cation diffusivity on the GaAs(001) surface. For the example of In/GaAs(001)-c(4x4) it is shown that the binding of In is increased when the substrate lattice is expanded. The diffusion barrier \Delta E(e) has a non-monotonic strain dependence with a maximum at compressive strain values (e 0) studied. We discuss the consequences of spatial variations of both the binding energy and the diffusion barrier of an adatom caused by the strain field around a heteroepitaxial island. For a simplified geometry, we evaluate the speed of growth of two coherently strained islands on the GaAs(001) surface and identify a growth regime where island sizes tend to equalize during growth due to the strain dependence of surface diffusion.Comment: 10 pages, 8 figures, LaTeX2e, to appear in Phys.

Effets d’une finition des agneaux à l’herbe sur les qualités nutritionnelles et gustatives de la viande

This study was carried out within the framework of the ECOLAGNO project which focuses on lambmeat production according to agro ecological practices. Two experiments were conducted for two successive yearsby the interregional center of information and research on ovine production (CIIRPO) in order to measure the effectof the type of lamb fattening on sensory and nutritional qualities of their meat, and on breeding performances. In2016 and 2017, three groups of 30 suckled lambs on pasture, weaned at 125 days of age, were compared. Thecontrol group was fattened with concentrated feed indoors and the other two groups were grass-fed in order tofinish lambs only on grass, either within a continuous grazing system on plots with multispecies crops such asgrass, legumes and tannin-rich plants or with cellular grazing. There were little differences between the threegroups for lamb breeding performances and carcass qualities. On average 50 kg RM of concentrated feed weresaved per lamb fattened on pasture. Grazing did not alter odor or flavor of lamb chops. However, the fatty acidprofile of meat was improved for grass-fed animals.Cette étude a été menée dans le cadre du projet ECOLAGNO s’intéressant à la production de vianded’agneau selon des pratiques agro-écologiques. Deux essais conduits sur deux années consécutives par le CentreInterrégional d’Information et de Recherche en Production Ovine (CIIRPO) avaient pour objectif de mesurerl’impact du mode de finition des agneaux, à l’herbe ou en bergerie, sur les qualités gustatives et nutritionnelles dela viande, ainsi que sur les aspects zootechniques. En 2016 et 2017, trois lots de 30 agneaux à l’herbe, allaitéspuis sevrés à 125 jours, ont été comparés. Le témoin était fini en bergerie avec un aliment concentré, les deuxautres au pâturage dans l’objectif de finir les agneaux exclusivement avec de l’herbe : l’un en pâturage continu surdes parcelles multi-espèces composées de graminées, légumineuses et plantes riches en tanins ; l’autre enpâturage cellulaire. Les performances zootechniques et les qualités de la carcasse des agneaux sont peudifférentes entre les trois lots. L’économie de concentré s’est située en moyenne à 50 kg brut par agneau avec unefinition à l’herbe. Il n’y a pas eu de dégradation de l’odeur ou de la flaveur des côtelettes lors des finitions aupâturage ; en revanche, le profil en acides gras des viandes a été amélioré

Establishing a generalized polyepigenetic biomarker for tobacco smoking

Large-scale epigenome-wide association meta-analyses have identified multiple 'signatures'' of smoking. Drawing on these findings, we describe the construction of a polyepigenetic DNA methylation score that indexes smoking behavior and that can be utilized for multiple purposes in population health research. To validate the score, we use data from two birth cohort studies: The Dunedin Longitudinal Study, followed to age-38 years, and the Environmental Risk Study, followed to age-18 years. Longitudinal data show that changes in DNA methylation accumulate with increased exposure to tobacco smoking and attenuate with quitting. Data from twins discordant for smoking behavior show that smoking influences DNA methylation independently of genetic and environmental risk factors. Physiological data show that changes in DNA methylation track smoking-related changes in lung function and gum health over time. Moreover, DNA methylation changes predict corresponding changes in gene expression in pathways related to inflammation, immune response, and cellular trafficking. Finally, we present prospective data about the link between adverse childhood experiences (ACEs) and epigenetic modifications; these findings document the importance of controlling for smoking-related DNA methylation changes when studying biological embedding of stress in life-course research. We introduce the polyepigenetic DNA methylation score as a tool both for discovery and theory-guided research in epigenetic epidemiology.This article is freely available via Open Access.
