E-Government Challenges and the Role of Political Leadership in Indonesia: The Case of Sragen
2008
In general, developing countries are lagging behind in e-government adoption compared to developed countries. Within Indonesia, there is a huge disparity in e- government implementation between districts. This study presents e-government challenges and the role of political leadership in the rural district of Sragen, one of the leading districts in implementing e-government in the country. The study focuses on the supply-side of e- government, and categorises the challenges in three main areas; management, infrastructure, and human factors. Initiatives taken to deal with these challenges are presented and strong political leadership is found to play an important role.
Final Reflections: Global Challenges from Innovation and Connectivity
2020
Lattemann et al. summarize the discussions in the edited book on Huawei goes Global—with Vol. I examining the major global threads caused by the rise of tech-giant Huawei. They recap the debate about the tensions between China and the Western world about global leadership, geopolitical power, national security, ideological, and economic threats, global connectivity, and about the shape of the upcoming technological world order. The culminating point is the question about the link between Huawei and the Chinese Government. The 5G standard, pushed by Huawei, has the power to change the world. The closeness of the ties between Huawei and the Chinese Government will decide if the world will end…
Cluster Preface: Heterogeneous Catalysis
2016
International audience; Jean-Cyrille Hierso is full professor of Chemistry since 2009, heading the group of ‘Organometallic Chemistry and Catalysis’ at the Institute of Molecular Chemistry at the University of Bourgogne Franche-Comté (UBFC). He has interest in the fields of organometallic chemistry, ligand design, homo- and heterogeneous catalysis, chemical physics, and material sciences. In 2011 he was awarded the National Prize for Coordination Chemistry from the French Chemical Society (SCF), and at the end of 2012 he was elected a junior Member of the French Professors Academy ‘Institut Universitaire de France’ (IUF).Yasuhiro Uozumi is a full professor at the Institute for Molecular Sci…
Los códigos de buen gobierno ¿son útiles para mitigar los pseudoliderazgos públicos?
2021
International audience; Leadership is one of the main roles of institutions and the lack of integrity of certain leaders affects the decision logic. The corruption of leadership degenerates into a pseudo-leadership which benefits from the principle of hierarchy that exists in all organizations. The lack of integrity of the leaders affects decision making and the structure of the organization. Corrupt dynamics often show regular and organized behavior because they adapt to an institutionalized script and to the existence of interpersonal networks. Corruption cases have stimulated in the last decade the elaboration of a legislative repertoire of codes of good governance in public administrati…
Dosimetric perturbations of a lead shield for surface and interstitial high-dose-rate brachytherapy.
2014
In surface and interstitial high-dose-rate brachytherapy with either (60)Co, (192)Ir, or (169)Yb sources, some radiosensitive organs near the surface may be exposed to high absorbed doses. This may be reduced by covering the implants with a lead shield on the body surface, which results in dosimetric perturbations. Monte Carlo simulations in Geant4 were performed for the three radionuclides placed at a single dwell position. Four different shield thicknesses (0, 3, 6, and 10 mm) and three different source depths (0, 5, and 10 mm) in water were considered, with the lead shield placed at the phantom surface. Backscatter dose enhancement and transmission data were obtained for the lead shields…
Searches for transverse momentum dependent flow vector fluctuations in Pb-Pb and p-Pb collisions at the LHC
2017
The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at $\sqrt{s_{\rm NN}}=$ 2.76 TeV and p-Pb collisions at $\sqrt{s_{\rm NN}}=$ 5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region $|��|<0.8$ as a function of centrality and transverse momentum $p_{\rm T}$ using two observables, to search for evidence of $p_{\rm T}$-dependent flow vector fluctuations. For Pb-Pb collisions at 2.76 TeV, the measurements indicate that $p_{\rm T}$-dependent fluctuations are only present for the second order flow vector. Similar results hav…
Functionalized halloysite nanotubes for enhanced removal of lead(II) ions from aqueous solutions
2018
In this study, environmental friendly halloysite nanotubes and their amino derivatives were used as adsorbent materials for lead(II) ions. The adsorption ability of both nanomaterials towards Pb2+ ions has been studied in NaClaq, at I = 0.1 mol L−1, in the pH range 3–6. Moreover, the effect of ionic strength on the adsorption process was evaluated at the pH of maximum efficiency of the adsorbent materials. Kinetic and equilibrium experiments were carried out by using the Differential Pulse Anodic Stripping Voltammetry (DP-ASV) technique to check the metal ion concentration in solution after contact with the two adsorbents. Different isotherm and kinetic equations were used to fit the experi…
European leaders unmasked: Covid-19 communication strategy through Twitter
2020
[EN] The coronavirus disease Covid-19 (SARS-CoV-2) pandemic is exacting a huge toll on individuals, families, communities, and societies across the world. The study of public communication is a key aspect for slowing the spread of the virus and therefore reducing the death rate. This article analyses political leaders' crisis communication during the Covid-19 pandemic of the most affected European countries, Boris Johnson (United Kingdom), Emmanuel Macron (France), Pedro Sanchez (Spain) and Giuseppe Conte (Italy), in addition to Tedros Adhanom as a representative of the World Health Organisation (WHO) and Ursula Von der Leyen President of the European Union (EU). The study focuses on the vi…
The human side of leadership: exploring the relationship between servant leadership, organisational facilitators and happiness at work
2018
Although human resource management (HRM) research has established a significant relationship between leadership styles and different attitudinal outcomes, few studies have considered the important role of organisational facilitators as a more proximal outcome of servant leadership to explain happiness at work (HAW). This paper explores the relationships between servant leadership, organisational facilitators and HAW, based on the leader-member exchange (LMX) and job-demands resources (JD-R) theories. Individual-level analyses from a sample of 189 machine operators revealed that organisational facilitators fully mediate the relationship between servant leadership and HAW. The discussion revi…
Liderazgo femenino y felicidad en el trabajo: el papel mediador del intercambio líder-colaborador
2018
Objetivo: el objetivo de este artículo es examinar el papel del liderazgo femenino en la felicidad en el trabajo de sus colaboradores. Además, se analiza el papel mediador de la relación entre el líder y el colaborador, entendida como el intercambio líder-colaborador (LMX). Método: se ha utilizado la encuesta como método de investigación; se analizaron datos cuantitativos a nivel individual a través de modelos de ecuaciones estructurales. La muestra está compuesta por 292 empleados no directivos del sector hotelero español, para los que se analiza su percepción individual acerca de las variables objeto de estudio. Resultados: los resultados revelan que el liderazgo femenino ejerce un papel …
