Job crafting and organizational commitment: The mediating role of person-job fit in the food and beverage sector

Purpose – Job crafting plays an essential role in job design since it is a new approach from the employee’s perspective to the manager. However, little research has investigated the hotel industry’s job crafting, particularly in the food and beverage department. Therefore, this study examines the relationship between job crafting and organizational commitment through the mediating role of person-job fit in the food and beverage department in five-star hotels. Design/methodology/approach – This study presents a conceptual framework with eight constructs. In this study, a self-administered questionnaire was used to collect data from full-time food and beverage employees in a five-star hotel. The proposed model was examined using confirmatory factor analysis, reliability analysis, validity analysis, standardized path coefficients, and the Sobel test for mediation analysis. Findings – According to the findings of this study, job crafting factors impact the person-job fit of food and beverage employees. The results also demonstrate that job crafting, and organizational commitment are mediated by person-job fit. The originality of the research – This paper adds a new chain to job design practices in the hospitality industry (i.e., job crafting leads to person-job fit, which enhances employees’ organizational commitment). Practical implications – Employee job crafting impacts the hotel by improving the fit of employees to their jobs, which leads to higher organizational commitment. As a result, hotel job designers should update their job design methodologies to include job crafting practices for hospitality employees

Preparation Critical Success Factors for Public Private Partnership (PPP) Projects in Palestine

Public Private Partnership (PPP) is a well-established method for incorporating the private sector to deliver a service or implement a project. PPP projects are a new concept in Palestine. The aim of this study is to explore the critical success factors (CSFs) for PPP projects in Palestine. A structured questionnaire was distributed to 45 experts from different sectors to identify and rank the critical success factors of PPP projects. The CSFs of PPP projects are stability of political situation, clear and detailed contract, existence of a sound economic policy, reliable delivery of service, analysis and allocation of risks, suitable legal framework, experienced private sector, profitability to the private sector, and accepted level of toll / tariff for a project. This study recommended that the government have to create a legal PPP framework and should establish PPP standard guidelines and processes to guide the implementation of PPP projects by stakeholders

Safety and e?ectiveness of microvascular decompression for treatment of hemifacial spasm through mini craniotomy

Background: The hemifacial spasm (HFS) defined as involuntary intermittent twitching of the muscles of the face (usually unilateral). The spasms characteristically begin around the eye and then extend to affect other muscles of the ipsilateral face. It is caused by vascular element compressing the facial nerve that may be either the anterior or the posterior inferior cerebellar arteries in most cases. Objective of our work: to describe the operative technique (pearls and common mistakes), the efficacy and morbidity of microvascular decompression technique for hemifacial spasm through mini craniotomy, determine the prognostic factors affecting success rate of the surgery. Material & method: A retrospective study of 23 cases of hemifacial spasm treated by mini craniotomy retro sigmoid approach and microvascular decompression at neurosurgery dept., Mansoura University Hospital in last 10 years was investigated. This include Epidemiological, clinical and imaging details, selected treatment options and patients’ outcome. Results: complete resolving of symptoms was conducted in 19 cases 82.6% while reoperated in 2 cases with improvement in one case. Facial palsy appeared post-operative in 6 cases 4 of them improved in 3 months, transient hearing loss in 4 cases17.4% which improved later, cerebrospinal fluid leak appeared in 3 cases 13% which managed conservatively. Conclusions: MVD relieves symptoms of HFS in about 80% of patients while recurrence still in low percentage. The study reported low permanent Complications and generally transient

INVESTIGATION OF THE CLINICAL SIGNIFICANCE OF ESCITALOPRAM-INDUCED ELECTROCARDIOGRAPHIC CHANGES IN MEN: A PILOT OBSERVATIONAL STUDY

Objective: We sought to investigate the clinical significance of secondary electrocardiographic (ECG) changes in men after using escitalopram. Methods: This pilot observational cohort study recruited male patients taking escitalopram for at least 6 mo in Mental Hospital of Qassim. All patients underwent a 12-lead ECG examination. We also measured the heart rate (HR), QTc, and QRS interval. Data on all related medical conditions and medications were recorded. Results: Fifty-three men were recruited, with a mean age of 37.39±8.39 y: 34.4% and 31.1% of these patients were taking escitalopram for depression and anxiety, respectively. The mean dose of escitalopram was 14.35 mg. Observations showed that 20.9% of the patients taking escitalopram had a fast HR (>100 beats/min [bpm]), indicative of sinus tachycardia, whereas 11.4% of patients had a slow HR (<60 bpm). The mean QT and QTc in patients taking escitalopram were 366.62±28.69 and 398.92±16.15 ms, respectively. Conclusion: Low doses of escitalopram resulted in minimal clinically significant changes. Thus, patients should be monitored when doses are escalated further

Electrical Properties of Partial Carbonized Nanoporous Resin Based on Resorcinol-Formaldehyde

Abstract: Organic xerogel compounds were prepared by sol-gel method from resorcinol-formaldehyde mixtures in acetone using picric acid as catalyst. The electrical properties of the obtained nanoporous carbon structures were explored by changing the pyrolysis temperature. In this study the electrical conductivity σ can be expressed as σ =/σ 0 exp(-Eσ/kT), where Eσ depends on the carbonized temperature. The dc and ac conductivities of the obtained amorphous carbon have been investigated from 80 to 300 °C and in the frequency range between 40 and 10 6 Hz for samples pyrolysed at different temperatures in the insulator-metal transition range. The temperature dependence of samples pyrolysed at low temperatures (T p =600-675 °C) follows a Mott law, whereas samples pyrolysed at high temperature (T p =1000 °C) show an Arrhenius dependence

INSULIN-MIMETIC ACTIVITY OF STEVIOSIDE ON DIABETIC RATS: BIOCHEMICAL, MOLECULAR AND HISTOPATHOLOGICAL STUDY

Background: Stevioside has been used as a medication for reducing glucose levels in diabetic patients. The exact mode of action is still unclear. Therefore, the current study outlines the molecular and biological roles of stevioside in treatment of diabetes. Materials and Methods: induced diabetic male wistar rats treated with stivioside and metformin as therapy for diabetic rats. Biochemical, molecular and histopathological studies have been done to evaluate the therapeutic effect of stevioside on minimizing levels of glucose in diabetic rats. Results: Stevioside administration normalized kidney and liver biomarkers, restored alterations in antioxidants activity and lipid profiles. Moreover, stevioside increased insulin and leptin secretion that are decreased in diabetic rats to the normal levels.For mRNA expression, stevioside up-regulated the expressions of PK and IRS-1 genes which are down-regulated in diabetic rats, and was very effective in down-regulation of CPT-1 mRNA expression. At the cellular levels; stevioside normalized the histopathological changes induced in pancreas. Conclusion: Stevioside has insulin like effects and it is useful for diabetic patient’s therapy

Interest of First Laparoscopy in the Etiological Diagnosis of Isolated Exudative Ascites

The purpose of this research article was to determine the contribution of performing laparoscopy first in the etiological diagnosis of isolated exudative ascites. Our retrospective descriptive study had been performed over 15 years and included 46 patients who had undergone exploratory laparoscopy for exudative ascites. The average age of the patients was 52 years. Biological and morphological examinations contributed to making the etiological diagnosis. Therefore, diagnostic laparoscopy was indicated. Peritoneal carcinomatosis and tuberculosis were the most common causes seen in 34.2% and respectively 65.8% of cases. Visual laparoscopic diagnosis was peritoneal carcinomatosis in 16 cases and peritoneal tuberculosis in 28 cases, indecisive in one case and biliary ascites in one case. The histological diagnosis was peritoneal tuberculosis in 24 cases and peritoneal carcinomatosis in 12 cases and there were 9 cases of rare diagnoses. Peritoneal biopsies were negative in 2 cases for which the etiological diagnoses were kidney failure in one case and hypothyroidism in the other case. The postoperative recovery was simple in 42 cases (91.3%). The complications were: an accidental rupture of the left diaphragmatic dome in one case (2.1%), gastrointestinal bleeding in the immediate postoperative period in two cases (4.2%) and infected ascites in one case (2.1%). The post-operative scapular pain was reported in 4.2% of our patients. Operative mortality in our patients was nil. The overall care had an average cost of 1685.7 dinars for each of our patients, with extremes ranging from 1055.7 to 3605.7 dinars. For patients with isolated exudative ascites that should have been explored through laparoscopy first, the average cost would be 130.1 dinars, with a material gain for each of 1555.6 dinars. This attitude could also allow a reduction in the mean hospital stay (which was 27 days to few days) associated with early treatment. Our study confirms the interest in laparoscopy first with peritoneal biopsies as part of the etiological diagnosis of isolated exudative ascites

Sperm collection and storage for the sustainable management of amphibian biodiversity

Current rates of biodiversity loss pose an unprecedented challenge to the conservation community, particularly with amphibians and freshwater fish as the most threatened vertebrates. An increasing number of environmental challenges, including habitat loss, pathogens, and global warming, demand a global response toward the sustainable management of ecosystems and their biodiversity. Conservation Breeding Programs (CBPs) are needed for the sustainable management of amphibian species threatened with extinction. CBPs support species survival while increasing public awareness and political influence. Current CBPs only cater for 10% of the almost 500 amphibian species in need. However, the use of sperm storage to increase efficiency and reliability, along with an increased number of CBPs, offer the potential to significantly reduce species loss. The establishment and refinement of techniques over the last two decades, for the collection and storage of amphibian spermatozoa, gives confidence for their use in CBPs and other biotechnical applications. Cryopreserved spermatozoa has produced breeding pairs of frogs and salamanders and the stage is set for Lifecycle Proof of Concept Programs that use cryopreserved sperm in CBPs along with repopulation, supplementation, and translocation programs. The application of cryopreserved sperm in CBPs, is complimentary to but separate from archival gene banking and general cell and tissue storage. However, where appropriate amphibian sperm banking should be integrated into other global biobanking projects, especially those for fish, and those that include the use of cryopreserved material for genomics and other research. Research over a broader range of amphibian species, and more uniformity in experimental methodology, is needed to inform both theory and application. Genomics is revolutionising our understanding of biological processes and increasingly guiding species conservation through the identification of evolutionary significant units as the conservation focus, and through revealing the intimate relationship between evolutionary history and sperm physiology that ultimately affects the amenability of sperm to refrigerated or frozen storage. In the present review we provide a nascent phylogenetic framework for integration with other research lines to further the potential of amphibian sperm banking

Primary resistance to clarithromycin, metronidazole and amoxicillin of Helicobacter pylori isolated from Tunisian patients with peptic ulcers and gastritis: a prospective multicentre study

<p>Abstract</p> <p>Background</p> <p>The frequency of primary resistance to antibiotics in H. pylori isolates is increasing worldwide. In Tunisia, there are limited data regarding the pattern of H. pylori antibiotic primary resistance.</p> <p>Aim</p> <p>To evaluate the primary resistance of H. pylori to clarithromycin, metronidazole and amoxicillin and to detect the mutations involved in clarithromycin resistance.</p> <p>Materials and methods</p> <p>273 strains isolated from adults and children were enrolled. The primary resistance to clarithromycin, metronidazole and amoxicillin was evaluated by means of E-test minimal inhibitory concentration (MIC). The real-time PCR using Scorpion primers was performed in all cases to assess clarithromycin primary resistance and point mutations involved.</p> <p>Results</p> <p>No resistance to amoxicillin was detected. For adults, resistance to clarithromycin and metronidazole was found respectively in 14.6% and 56.8%, and respectively in 18.8% and 25% in children. Overall, the rates of global primary resistance to clarithromycin and metronidazole in Tunisia were respectively determined in 15.4% and 51.3%.</p> <p>By the use of Scorpion PCR, the A2143G was the most frequent point mutation observed (88.1%), followed by the A2142G (11.9%); the A2142C was not found and 18 of 42 patients (42.8%) were infected by both the resistant and the susceptible genotype.</p> <p>The association of clarithromycin resistance with gender was not statistically significant, but metronidazole resistant strains were isolated more frequently in females (67.8%) than in males (32.2%) and the difference was significant. As for gastroduodenal diseases, the difference between strains isolated from patients with peptic ulceration and those with non peptic ulceration was not statistically significant. When about the distribution of resistant strains to clarithromycin and metronidazole between the three Tunisian cities (Tunis, Menzel Bourguiba and Mahdia), the difference was not statistically significant.</p> <p>Conclusion</p> <p>Local data regarding the primary resistance of H. pylori to clarithromycin, metronidazole and amoxicillin and the main genetic mutation involved in clarithromycin resistance in vivo (A2143G) are necessary to prove a clear need for a periodic evaluation of antibiotic consumption and new therapeutic strategies in Tunisia in order to avoid the emergence of resistant strains.</p
