Walking at the edge: How tempo-spatial nexus forms HRM practices in project-based organizations.

Introduction: Research has scrutinized the role of different HRM practices in Project-based Organizations (PBOs) mostly in terms of project success and articulated the challenges of traditional HRM to reconcile with the project context. Nevertheless, HRM practices have been addressed less in PBOs with a practice-based research lens. Particularly, the role of tempo-spatial nexus in shaping such practices in this organizational form has been under-researched, although PBOs provide a very suitable context for doing so. Methods: Drawing upon a comparative case study in the oil and gas industry of Scotland and adopting a practice-based approach, this research aims to shed light on how HRM practices are shaped and re-shaped in the project-based context. The study, specifically, scrutinizes the role of temporality and space in the formation, adoption and adaptation of HRM practices in these organizational forms. Results and discussion: The findings reveal that project characteristics, specifically their duration, size and technical properties, induce different temporalities that along with different work locations and inter-organizational relationships, impact HRM practices as a threefold structure.

The association between exhaled nitric oxide and sleep apnea: the role of BMI.

BACKGROUND: Obstructive sleep apnea syndrome is associated with airway inflammation. Measurement of exhaled nitric oxide is a non-invasive method for evaluation of airway diseases. It seems that obesity is an exacerbating factor for airway inflammation. We aimed to evaluate the changes of exhaled nitric oxide after sleep in patients suffering from OSA regarding BMI. METHOD: In 54 patients referred for polysomnography, exhaled nitric oxide measurements were performed before and after sleep. Subjects were divided into three categories: normal, obese with sleep apnea and non-obese, based on polysomnographic recordings and BMI. RESULTS: 47 subjects had abnormal apnea/hypopnea index (AHI mean = 39.7) and 7 were normal regarding AHI (AHI mean = 3.0). BMI was significantly correlated to AHI, number of desaturations and hypoxia. Among those with apnea, 31 subjects were obese and 16 were non-obese. Exhaled nitric oxide levels in normal and OSA subjects showed no significant change, but a significant increase was found in obese patients with apnea (14.7 pre-sleep mean, 20.0 post-sleep mean). CONCLUSIONS: Obesity is an effective factor in the inflammation of airways in patients with obstructive apnea.

Prevalence of Cardiovascular Risk Factors among Tile and Ceramic Workers in Yazd, Iran.

Introduction. Cardiovascular disorders (CVDs) are among the most important diseases in the world and determination of their risk factors is essential for primary and secondary prevention. This study aimed to evaluate these risk factors in workers of tile and ceramic industry, a main industry in Yazd. Materials and Methods. In a cross-sectional study, 1075 tile and ceramic workers were selected by simple sampling method. BMI, blood pressure, FBS, and lipid profile were measured and compared to international standards. Results. 731 individuals (68%) had at least one risk factor, and 52%, 12%, 3%, and 0.7% had one, two, three, and four risk factors, respectively. The most common risk factor was abnormal BMI (49.6%); low HDL (48.4%) and high TG (14.1%) were in the second and third orders. Conclusion. This study showed a relatively high prevalence for CVD risk factors among tile and ceramic workers. Low HDL, high TG, and overweight were the most frequent risk factors in this population.
