Maintenance Technicians

From its initial conceptualization as emotional exhaustion, cynicism, and reduced personal efficacy for the help professions, burnout has received increasing attention in modern times, especially after the 2019 WHO’s inclusion of this syndrome in the ICD-11 list. Burnout can be measured using several psychometric instruments that range in dimensionality, number of items, copyrighted, and free use formats. Here, we report the psychometric properties of data gathered with the Oldenburg Burnout Inventory (OLBI) in a sample of Portuguese Aircraft maintenance technicians. As far as we know, this is the first study addressing the burnout syndrome in this occupational group. Data gathered with the OLBI displayed good evidence of validity related to internal structure, to other variables, with good evidence of reliability. We showed that burnout significantly correlated with mental and physical fatigue emphasizing the vital critical role that these variables play with safety in the aviation industry.

Collaboration plays a critical role in fostering innovation and value creation in the aviation sector. However, how factors and connections relate to the achievement of innovative outcomes in aviation require further investigation. This study investigates the key factors that create a conceptual framework by conducting a literature review and an archival analysis of news articles. The model proposed involves factors such as strategic decision-making; networking and partner choice; cultural context, values, behaviour and compatibilities; collaboration configuration; issues and risks shared; skills, capacities and experience; infrastructure and resources available; engagement activities; knowledge transfer, absorption and appropriation; collaboration management; communication flows; external environment and demand; and expectations and outcomes. Promising collaborations are also indicated in areas where the framework could be adopted to increase partnerships and outcomes. Also, we highlight best practice examples from leading organizations, such as International Airlines Group (IAG), Emirates Airline, Singapore Airlines, Boeing and JetBlue, to provide insights into existing collaborations that have led to innovation and value creation in this sector.

Abstract Objective: Multiple sclerosis (MS) is often associated with cognitive deficits. Accurate evaluation of the MS patients’ cognitive performance is essential for diagnosis and treatment recommendation. The Brief International Cognitive Assessment in Multiple Sclerosis (BICAMS), widely used cognitive testing battery, examines processing speed, verbal and visuospatial learning, and memory. Our study aims to examine the psychometric properties of an Arabic version of the BICAMS and to provide normative values in a Lebanese sample. Method: The BICAMS, comprised of the Symbol Digit Modalities Test (SDMT), Brief Visuospatial Memory Test-Revised (BVMT-R), and a newly developed verbal learning/memory test, the Verbal Memory Arabic Test (VMAT), were administered on healthy subjects and MS patients. The sample consisted of 180 healthy individuals, of whom 63 were retested after 2–3 weeks. Forty-three MS patients matched with 43 healthy subjects based on age, sex, and years of education were assessed. A sample of 10 MS patients was also examined on two occasions. Test–retest reliability and criterion-related validity were examined, and regression-based norms were derived. Results: The test–retest correlations showed good evidence of reliability with coefficients ranging between 0.64 and 0.73 in the healthy sample, and between 0.43 and 0.92 in the MS sample. The BICAMS was able to discriminate between MS patients and matched healthy participants on the SDMT and BVMT-R. Normative data were comparable to other studies. Conclusions: This new Arabic version of the BICAMS shows initial good psychometric properties. While good evidence of VMAT’s reliability was shown in the healthy participants, less test–retest reliability in this tool was seen in the MS group, and partial criterion-related validity was evident. This renders further examination of the VMAT. We provide regression-based norms for a Lebanese sample and encourage the use of this battery in both research and clinical settings.

Background: Experiences that a child or adolescent goes through play a critical role in their development as an individual. To understand the world of adolescents and their mental health and well-being, it would be important to be able to access their experiences. Therefore, an objective measure to assess experiences is necessary. The study aimed to develop a scale to assess experiences and establish their psychometric properties. Materials and methods: My Experiences Scale (MES) is a newly developed 50-item, multiple-choice, self-report measure. Various steps involved in developing the MES and establishing its psychometric properties have been elaborated. The study was carried out across four phases, and the sample consisted of 1,260 school-going children and adolescents. The participants were representative of both genders, a wide age range, and diverse socioeconomic backgrounds. Results: MES was found to have good internal consistency (Alpha 0.85) and test–retest reliability (0.96). MES was found to have significant correlations with Strengths and Difficulties Questionnaire and global self-worth. Conclusions: The newly developed experiences scale shows promising psychometric properties and a wide scope for application.

Angiotensin Type

Angiotensin type 1 receptors (AT1Rs) play a critical role in a variety of physiological functions and pathophysiological states. They have been strongly implicated in the modulation of sympathetic outflow in the brain. An understanding of the mechanisms by which AT1Rs are regulated in a variety of disease states that are characterized by sympathoexcitation is pivotal in development of new strategies for the treatment of these disorders. This review concentrates on several aspects of AT1R regulation in the setting of chronic heart failure (CHF). There is now good evidence that AT1R expression in neurons is mediated by activation of the transcription factor activator protein 1 (AP-1). This transcription factor and its component proteins are upregulated in the rostral ventrolateral medulla of animals with CHF. Because the increase in AT1R expression and transcription factor activation can be blocked by the AT1R antagonist losartan, a positive feedback mechanism of AT1R expression in CHF is suggested. Oxidative stress has also been implicated in the regulation of receptor expression. Recent data suggest that the newly discovered catabolic enzyme angiotensin-converting enzyme 2 (ACE2) may play a role in the modulation of AT1R expression by altering the balance between the octapeptide ANG II and ANG- (1–7). Finally, exercise training reduces both central oxidative stress and AT1R expression in animals with CHF. These data strongly suggest that multiple central and peripheral influences dynamically alter AT1R expression in CHF.
