This study aims to explore the relationship between transformational leadership and organizational commitment in multinational companies (MNCs) in Morocco.,The study used a sample size of 256 employees to attain results regarding a relationship between transformational leadership and organizational commitment. Proposed hypotheses are tested through regression analysis.,Findings show a relationship between transformational leadership and organizational commitment. Organisations use different leadership styles and thus act differently. However, tranformational leadership shows its importance in leading organisations who aim to be constantly committed.,To the authors’ knowledge, this is the first research in North Africa that investigates the level of transformational leadership and organizational commitment in MNCs.

Ovim radom ispituje se da li i na koji način politički poredak u Bosni i Hercegovini determiniran logikom etnopolitike sadrži i producira subverzivni potencijal za vlastitu negaciju. Ideja se postepeno javljala u kontekstu različitih protesta u proteklih pet godina, ali se kao naučno pitanje ozbiljnije oblikovalo tek stapanjem protesta “Pravda za Dženana” i “Pravda za Davida” 2018. godine. Kroz proteste se od jedinstvenog matičnog broja i zdravstva preko radničkih prava i demobilisanih boraca kao politiziranih tijela par excellence pa sve do institucionalizirane instrumentalizacije smrti uočava izražena biopolitička dimenzija sa potpisom etnodeterminizma. Politološkim čitanjem odnosa između kontrahegemonijskih narativa odozdo i njihove sve vidljivije kriminalizacije odozdo, autor problematizira kako ono što se ovdje naziva biopolitikom etnodeterminizma producira narativ otpora kao mogućnost koja osvjetljavanjem naličja samog sistema dovodi u pitanje osnovu njegove legitimacije.

Abstract Purpose: To investigate contemporary results of percutaneous transluminal renal angioplasty (PTRA). Materials and Methods: A multicentre retrospective study analysing all patients treated with PTRA for primary symptomatic renal artery stenosis (RAS) between 2010 and 2013 at four tertiary centres. Procedures during the preceding four years were counted to evaluate for change in PTRA frequency. Results: The number of PTRA procedures decreased by approximately 50% from 2006 to 2013. Patients treated in the post-ASTRAL period (n = 224) had a significant reduction in mean systolic pressure (168 to 146 mmHg, p < 0.01), diastolic pressure (84 to 76 mmHg, p < 0.01), number of anti-hypertensive drugs (3.54 to 3.05, p < 0.01), and anti-hypertensive treatment index (21.75 to 16.92, p < 0.01) compared to before PTRA. These improvements were maintained at one year and at the last clinical evaluation after a mean follow-up of 4.31 years. Renal function increased transiently without sustained improvement, or deterioration, during later follow-up. Thirteen patients (5.8%) eventually required dialysis, nine of these had eGFR <20 ml/min/1.73 m2 before PTRA. There was no difference in outcomes between subgroups differentiated by different indications for PTRA. Conclusion: The frequency of PTRA has decreased, indicating a higher threshold for invasive treatment of RAS in recent years. The reduction in blood pressures, the reduced need for anti-hypertensive medication, and stabilization of renal function over time suggest a clinical benefit for most patients who are now being treated with PTRA.

COVID-19 pandemic is plaguing the world and representing the most significant stress test for many national healthcare systems and services, since their foundation. The supply-chain disruption and the unprecedented request for intensive care unit (ICU) beds have created in Europe conditions typical of low-resources settings. This generated a remarkable race to find solutions for the prevention, treatment and management of this disease which is involving a large amount of people. Every day, new Do-It-Yourself (DIY) solutions regarding personal protective equipment and medical devices populate social media feeds. Many companies (e.g., automotive or textile) are converting their traditional production to manufacture the most needed equipment (e.g., respirators, face shields, ventilators etc.). In this chaotic scenario, policy makers, international and national standards bodies, along with the World Health Organization (WHO) and scientific societies are making a joint effort to increase global awareness and knowledge about the importance of respecting the relevant requirements to guarantee appropriate quality and safety for patients and healthcare workers. Nonetheless, ordinary procedures for testing and certification are currently questioned and empowered with fast-track pathways in order to speed-up the deployment of new solutions for COVID-19. This paper shares critical reflections on the current regulatory framework for the certification of personal protective equipment. We hope that these reflections may help readers in navigating the framework of regulations, norms and international standards relevant for key personal protective equipment, sharing a subset of tests that should be deemed essential even in a period of crisis.

The EU has long been suffering a legitimacy crisis. In this article we argue that multilingual Europarties, that is, European political parties operating in all the various languages spoken by their members via interpreting and translation, rather than resorting to a lingua franca, could contribute to providing an effective democratic linkage between EU citizens and EU institutions. Moreover, by drawing inspiration from an analysis of Belgium, Canada and Switzerland, we argue that centripetal institutions such as an EU-wide electoral district, presidentialism, and direct democracy could provide favourable institutional conditions for the development of such multilingual Europarties.

IrO 2 is the most stable oxygen evolution reaction (OER) catalyst in acidic media and it has been widely used as co-catalyst to mitigate cell reversal damages in the anode of PEM fuel cells (PEMFCs). In this study, a mechanistic understanding of the degradation of an IrO 2 anode co-catalyst under transient operation of a PEMFC is provided. Thermogravimetric analysis (TGA) in reductive atmosphere (3.3 vol.% H 2 /Ar) shows that IrO 2 is not stable in H 2 containing atmosphere at operational temperatures of PEMFCs. By conducting a series of physical-chemical and electrochemical analyses, it is proven that H 2 under the operating conditions in a PEMFC anode can chemically reduce a few outer monolayers of the surface of IrO 2 nanoparticles to metallic Ir. The metallic Ir formed on the IrO 2 surface can then dissolve during fuel cell start-up/shut-down (SUSD) cycles. At least part of the dissolved Ir species formed in the anode electrode are shown to diffuse through the membrane to the cathode electrode, where they lead to a deterioration of the oxygen reduction reaction (ORR) activity of the Pt cathode catalyst. The consequences of Ir dissolution on the cell reversal tolerance of the anode are also discussed.

The information sharing among vehicles provides intelligent transport applications in the Internet of Vehicles (IoV), such as self-driving and traffic awareness. However, due to the openness of the wireless communication (e.g., DSRC), the integrity, confidentiality and availability of information resources are easy to be hacked by illegal access, which threatens the security of the related IoV applications. In this paper, we propose a novel Risk Prediction-Based Access Control model, named RPBAC, which assigns the access rights to a node by predicting the risk level. Considering the impact of limited training datasets on prediction accuracy, we first introduce the Generative Adversarial Network (GAN) in our risk prediction module. The GAN increases the items of training sets to train the Neural Network, which is used to predict the risk level of vehicles. In addition, focusing on the problem of pattern collapse and gradient disappearance in the traditional GAN, we develop a combined GAN based on Wasserstein distance, named WCGAN, to improve the convergence time of the training model. The simulation results show that the WCGAN has a faster convergence speed than the traditional GAN, and the datasets generated by WCGAN have a higher similarity with real datasets. Moreover, the Neural Network (NN) trained with the datasets generated by WCGAN and real datasets (NN-WCGAN) performs a faster speed of training, a higher prediction accuracy and a lower false negative rate than the Neural Network trained with the datasets generated by GAN and real datasets (NN-GAN), and the Neural Network trained with the real datasets (NN). Additionally, the RPBAC model can improve the accuracy of access control to a great extent.

The HERe2Cure project, which involved a group of breast cancer experts, members of multidisciplinary tumor boards (MTB) from health-care institutions in Bosnia and Herzegovina, was initiated with the aim of defining an optimal approach to the diagnosis and treatment of HER2 positive breast cancer. After individual multidisciplinary consensus meetings were held in all oncology centers in Bosnia and Herzegovina, a final consensus meeting was held to reconcile the final conclusions discussed in individual meetings. Guidelines were adopted by consensus, based on the presentations and suggestions of experts, which were first discussed in a panel discussion and then agreed electronically between all the authors mentioned. The conclusions of the panel discussion represent the consensus of experts in the field of breast cancer diagnosis and treatment in Bosnia and Herzegovina. The objectives of the guidelines include the standardization, harmonization, and optimization of the procedures for the diagnosis, treatment, and monitoring of patients with HER2-positive breast cancer, all of which should lead to an improvement in the quality of health care of mentioned patients. The initial treatment plan for patients with HER2-positive breast cancer must be made by a MTB comprised of at least: A medical oncologist, a pathologist, a radiologist, a surgeon, and a radiation oncologist/radiotherapist.
