LEADERSHIP AND JOB SATISFACTION – A REVIEW

The purpose of the present study is to provide a critical review of the relation between leadership and the levels of job satisfaction experienced by employees. An organization’s or institution’s leadership refers to its leader’s style of providing direction, implementing plans and motivating employees. Job satisfaction refers to the employees’ perceptions of their working environment, relations among colleagues, earnings and promotion opportunities. The review shows that contemporary job-related phenomena like job satisfaction are related to employees’ relations with colleagues and superiors, performance and perceptions of their organization’s specific culture. In addition, the employees’ preference of leadership style is likely to be affected by several factors, including demographic characteristics. It can be supported, therefore, that measuring and analyzing an institution’s leadership style in combination with its employees’ demographic and individual characteristics may lead to valuable conclusions, so that job satisfaction is promoted

Job Satisfaction, Role Conflict and Autonomy of employees in the Greek Banking Organization

AbstractThe aim of the present study is to measure the levels of job satisfaction, role conflict and autonomy of employees in the Greek Banking Organization. In addition, the investigation of the relation between role conflict and the dimensions of job satisfaction is being attempted and the regulatory impact of autonomy in the aforementioned relationship is being analyzed. For the measurement of job satisfaction in the present study, the Employee Satisfaction Inventory - ESI (Koustelios, 1991; Koustelios & Bagiatis, 1997) was used. The inventory was created using Greek employees as a sample. It included 24 items which measure six dimensions of job satisfaction: 1. Working conditions, 2. Salary, 3. Promotions, 4. Work itself, 5. Immediate superior and 6. The organization as a whole For the measurement of role conflict, the Role Questionnaire (Rizzo, House, & Lirtzman, 1970) was used. The scale consisted of eight items. Finally, for the measurement of employees’ autonomy a scale developed by Beehr (1976) was used. The scale consisted of four items. The results of the study confirmed previous findings, according to which role conflict is negatively correlated with job satisfaction. In addition, autonomy has a moderating role in the relation between role conflict and job satisfaction. Research findings like these should be taken into serious consideration by superiors and managers, so that job satisfaction among Greek bank employees is increased and promoted, leading to higher productivity and general well-being

TRADITIONAL TEACHING METHODS VS. TEACHING THROUGH THE APPLICATION OF INFORMATION AND COMMUNICATION TECHNOLOGIES IN THE ACCOUNTING FIELD: QUO VADIS?

Much emphasis has been placed in the higher education literature, to the understanding of the manner and process of providing education in the accounting discipline. Specifically, the emphasis on using innovative teaching practices such as information and communication technologies, the Internet as well as various computer programs, simulations, case studies on real and virtual work environments, have been investigated in an attempt to understand current demands and move the discipline forward. Following a thorough review of the relevant literature, this study aims to identify and present different views and research findings on the key issue of teaching accounting, internationally. The findings suggest that despite the availability of the former teaching practices, students mainly prefer personalized teacher-centered methods; they also recommend the aforementioned practices as ancillary tools to the traditional method, rather than key learning tools in the courses taken. These findings have obvious implications for the design of accounting course curricula by professional bodies and/or Higher Education Institutions in order to help graduates meet and adapt to the demands for professional competency development in the accounting field

Χρονολόγηση γεγονότων διασποράς επιδημίας HIV-1 υποτύπου Β με μεθόδους Μπεϋζιανής συμπερασματολογίας

Σκοπός της μελέτης ήταν η εκτίμηση της χρονολόγησης των δεδομένων διασποράς της επιδημίας του υπότυπου Β του ιού του HIV-1 με μεθόδους Μπεϋζιανής συμπερασματολογίας. Τα δεδομένα που χρησιμοποιήθηκαν είχαν συλλεγεί κατόπιν συστηματικής ανασκόπησης της βιβλιογραφίας από προηγούμενη ανάλυση (φυλογεωγραφίας) που είχε πραγματοποιηθεί σε αλληλουχίες από περισσότερους από 8,000 οροθετικούς. Αφού εξήχθει ένα αντιπροσωπευτικό δείγμα αλληλουχιών ,εκτιμήθηκε μια αρχική τοπολογία με μεθόδους μεγίστης πιθανοφάνειας. Χρησιμοποιώντας εν τέλει αυτή την αρχική τοπολογία ώστε να επιταχυνθεί υπολογιστικά η χρονολόγηση , εκτιμήσαμε την χρονική προέλευση της παγκόσμιας επιδημίας του υπότυπου Β του ιού του HIV-1 με μεθόδους Μπεϋζιανής συμπερασματολογίας.Goal of this study was the date origin estimation of the epidemic dispersion of HIV-1 subtype B global spread using Bayesian inference . The dating estimation was based on data collected from a prior systematic review of the literature which led to a phylogeographical analysis of over 8,000 HIV positive individuals. Initially we extracted a representative sample of sequences and estimated an initial topology using maximum likelihood methods. Finally, we used the abovementioned initial topology in order to computationally speed the dating process, we estimated using Bayesian inference the date origin of the global HIV-1 subtype B epidemic

JOB SATISFACTION AND JOB BURNOUT AMONG GREEK BANK EMPLOYEES

ABSTRACT The present investigation aims to study the feelings of job satisfaction and job burnout experienced by bank employees in Greece in correlation. The method which was preferred in the frame of the study was the quantitative research method. The tool which was used for the measurement of job satisfaction was the Employee Satisfaction Inventory, ESI, created by Koustelios, 1991. It included 24 questions, which measure six dimensions of job satisfaction: 1. Working conditions (5 questions), 2. Earnings (4 questions), 3. Promotions (3 questions), 4. Nature of work (4 questions), 5. Immediate superior (4 questions) and 6. The institution as a whole (4 questions) (total Chronbach's α = 0.75). The responses were given in a five-level Likert scale: 1 = I strongly disagree, 5 = I strongly agree. The tool which was used for the measurement of job burnout was the Maslach Burnout Inventory, MBI, created by Maslach and Jackson, 1986. The inventory included 22 questions measuring the three variables of job burnout: 1. Emotional Exhaustion (9 questions), 2. Depersonalization (5 questions), 3. Lack of personal accomplishment (8 questions) (total Chronbach's α = 0.70). The answers were given in a seven-level Likert scale: 0 = Never, 1 = A few times per year or less, 2 = Once per month or less, 3 = A few times per month, 4 = Once a week, 5 = A few times per week, 6 = Every day. High level of burnout occurs when we have high values on the scales of emotional exhaustion and depersonalization and low values in the range of personal accomplishment. Low job burnout occurs when we have low values on the scales of emotional exhaustion and depersonalization and high values in the range of personal accomplishment. The sample of the present study consisted of 230 employees of Greek banks and credit institutions. The results of the study showed that the feelings of job satisfaction and job burnout experienced by Greek bank employees occur in quite high levels. Furthermore, there is quite a strong negative correlation between the two variables. However, further investigation should be carried out in the Greek population, so that the phenomena of job satisfaction and job burnout are well studied and promoted

Validation of a new method to estimate energy use for space heating and hot water production from low-resolution heat meter data

One of the initiatives to reach the European decarbonization goal is the roll-out of smart heating meters in the building stock. However, these meters often record the total energy usage with only hourly resolution, without distinguishing between space heating (SH) and domestic hot water (DHW) production. To tackle this limitation, this paper presents the validation of a new methodology to estimate the SH and DHW from total measurements in different building types in three countries (Denmark, Switzerland, and Italy). The method employs a combined smoothing algorithm with a support vector regression (SVR) to estimate the different heating uses. The estimation results are compared with the different countries’ DHW compliance calculations. The comparison showed that the compliance calculations outperformed this method by considering the validation dataset characteristics

Neutrino-nucleus reactions in the delta resonance region

Reliable estimates of neutrino-nucleus reactions in the resonance-excitation region play an important role in many of the on-going and planned neutrino oscillation experiments. We study here neutrino-nucleus reactions in the delta-particle excitation region with the use of neutrino pion-production amplitudes calculated in a formalism in which the resonance contributions and the background amplitudes are treated on the same footing. Our approach leads to the neutrino-nucleus reaction cross sections that are significantly different from those obtained in the conventional approach wherein only the pure resonance amplitudes are taken into account. To assess the reliability of our formalism, we calculate the electron-nucleus scattering cross sections in the same theoretical framework; the calculated cross sections agree reasonably well with the existing data.Comment: 14 pages, 8 figures; typo, references and one figure adde

E-DYCE - Dynamic approach to the dynamic energy certification of buildings

The energy performance certification (EPC) scheme, introduced in the European Union approximately 20 years ago, has become the focus of the upcoming revision of the Energy Performance of Buildings Directive (EPBD). Despite its widespread use, the current EPC scheme has several shortcomings that need to be addressed. The Energy flexible DYnamic building Certification (E-DYCE) project has developed a dynamic approach to address these issues. The methodology includes a dynamic assessment of a building's energy needs and comfort conditions under standard and different from standard conditions of building use to support Performance Gap (PG) analyses. The E-DYCE approach includes a dynamic building performance simulation with comfort and energy-related key-performance indicators (KPIs) measured and calculated according to E-DYCE DEPC methodology. These KPIs can inform end-users about indoor environmental quality conditions decisive for building energy performance, aid building managers in detecting dysfunctions resulting in PG, and include energy performance indexes for heating, cooling, lighting, domestic hot water, and more. Overall, the E-DYCE approach offers dynamic, reliable, and customer-tailored information and optimization possibilities to end-users while potentially resolving known shortcomings of the existing EPC schemes
