Knowledge Retention within Small and Mediumsized Enterprises
2019
Abstract In the constantly changing nowadays economy, all organizations have to be prepared to embrace all technological innovation and become good competitors in the market place all over the world. This need puts a special emphasize on the ability of a company to evolve through employee ability to grow professional. The retention of good, qualified employee is a complex process, because of the importance of the knowledge for the financial efficiency of a company. This article aims is to examine knowledge retention as an advantage of companies in this era of information, an era in which organizations view their employees as the main sources of competitive edge, acknowledging, at the same t…
Task-oriented reading efficiency : interplay of general cognitive ability, task demands, strategies and reading fluency
2022
AbstractThe associations among readers’ cognitive skills (general cognitive ability, reading skills, and attentional functioning), task demands (easy versus difficult questions), and process measures (total fixation time on relevant and irrelevant paragraphs) was investigated to explain task-oriented reading accuracy and efficiency (number of scores in a given time unit). Structural equation modeling was applied to a large dataset collected with sixth-grade students, which included samples of dysfluent readers and those with attention difficulties. The results are in line with previous findings regarding the dominant role of general cognitive ability in the accuracy of task-oriented reading…
Investigating the success of ERP systems in Pakistan : end-users' perspective
2016
The global business environment is changing rapidly, and organisations from developing countries such as Pakistan have to re-engineer their business processes to meet the challenges of increased competition and rising customer expectations. Enterprise resource planning (ERP) systems intend to deliver many benefits, such as business automation, reduced operating costs, accurate demand forecasts, better decision-making and improved customer service. However, organisations adopting ERP systems encounter many types of problems that may lead to failures in processes, expectations and interactions. In order to address these failures, researchers have identified the critical success factors in the…
Sustainability in the restoration and management of the historic architecture in Palermo
2015
This research investigates the energy and environmental sustainability in the restoration and conservation of historic buildings. It focuses on the architectural heritage of Palermo, which can be a significant case study for the Mediterranean area. Its objective is to analyse the current energy performance of this historic architecture and its potential for energy improvement. Therefore, it aims at proposing a methodology to combine the enhancement of energy and environmental performances of the historic architecture of Palermo with the need of its material and aesthetic conservation, in the frame of the current regulations.
A study of solar panel efficiency in Latvian climate conditions
2020
With solar panels increasingly used in nearly zero energy building solutions it is important to clarify if the panels can achieve the efficiency indicators specified by their producers in real operation conditions. To determine the efficiency of poly- and monocrystalline panels depending on their spatial orientation and the seasons a set of test panels was installed in 2018 in Riga, Latvia for long-term monitoring of the amount of generated power and produced energy. Here we summarize the results of the first year of monitoring. Data indicate that orientation has high significance, very small amounts of energy are generated in autumn/winter and that there is a good correspondence of the act…
Photoelectrical Properties and Energetical Structure of Thin Films of Indandione Derivatives
2011
A sandwich type structure of two dimetilaminobenziliden-1,3-indandione (DMABI) derivatives placed between metal electrodes was made to investigate the photoelectrical properties of these derivatives. DMABI is an organic isolator with a wide energy gap and high quantum efficiency of the photogeneration, DMABI derivatives have received also considerable attention because of its large dipole moment and optical nonlinearities. Besides, since it is a photosensitive material, its use in solar systems is very promising. The energy gap of each material and combined system was observed from the spectral dependence of the quantum efficiency of the photoconductivity and results are compared with resul…
Rainwater reuse in urban areas: a mathematical model and a longterm modelling approach
2018
Natural water resources are becoming increasingly limited due to global-scale climate change and water availability issues have become so severe that they must be addressed. Given these issues, reuse of wastewater and rainwater provides a promising way to cope with water shortages. This paper describes an investigation into the efficiency of rainwater usage systems. A conceptual model was built to assess the behaviour of rainwater tanks and their effectiveness in coping with water shortages. The study is based on a long-term simulation (12 years) of different rainwater reuse tank schemes. The associated reductions in residential freshwater demand (water reuse efficiency) and wetweather runo…
Macroalgal responses to ocean acidification depend on nutrient and light levels
2015
Ocean acidification may benefit algae that are able to capitalize on increased carbon availability for photosynthesis, but it is expected to have adverse effects on calcified algae through dissolution. Shifts in dominance between primary producers will have knock-on effects on marine ecosystems and will likely vary regionally, depending on factors such as irradiance (light vs. shade) and nutrient levels (oligotrophic vs. eutrophic). Thus experiments are needed to evaluate interactive effects of combined stressors in the field. In this study, we investigated the physiological responses of macroalgae near a CO2 seep in oligotrophic waters off Vulcano (Italy). The algae were incubated in situ …
Trade-offs or Complements? : Balancing Diversified Stakeholder Expectations, Institutional Pressures, and Functional Demands in the Strategic Managem…
2019
While scholars and practitioners have warned that business schools are losing their edge in creating and disseminating relevant knowledge in the crosscurrent of environmental demands, the management and organization of higher education institutions (HEIs) have been described as “herding cats” and “organized anarchy”. The teaching–research nexus forms the cornerstone of academic organization and has a quintessential role in strategic management. However, despite the growing body of literature on HEIs’ teaching–research nexus, organization, and environmental changes, few studies have examined the interplay of the three. Therefore, this study combines two contingency-theory views to examine th…
