DECISION SUPPORT SYSTEM FOR POWER GENERATION MANAGEMENT FOR AN 110000+ GRT CRUISE SHIP

The aim of this work is to provide a methodology for the power generation optimization on large cruise ships in order to improve their operating efficiency, fuel saving and, consequently, to reduce exhaust gas emissions. The electrical load analysis is compared to the machinery reports of actual data in order to investigate if the estimated required power is appropriately close to the real power demand. Relevance is given to the average load of the diesel-generators, which expresses an indication of how the generators work. The model of the ship electric distribution system represents one of the main objectives of this work along with the power system simulations. These were developed through the definition of load profiles, both by the onboard recordings and by machinery reports data. Therefore, the same cruise profile is analyzed under different scenarios, the real and the optimized one, in order to highlight the critical state of the system and any possible margin for improvement.

Enhancing knowledge management in the PSS detailed design: a case study in a food and bakery machinery company

Most methodologies developed to support the Product-Service System (PSS) design consider the integration of service features into the product design from a high-level of abstraction and are usually focused on the conceptual phase, neglecting the detailed level of design. Besides, the Knowledge Management perspective is not considered in those methodologies, also affecting how new design knowledge is created, formalized, and shared across the company’s organization. The PSS Design GuRu Methodology, grounded on Concurrent Engineering and Design for X approaches, was developed to fill these issues. This study presents how the PSS Design GuRu Methodology can be incorporated into a PSS detailed design process in a B2B company operating in the food and bakery machinery sector, focusing the analysis on its contribution to promoting Knowledge Management. In particular, a detailed case of development and integration of a service feature—the installation service—to a product in the PSS scope is conducted. The PSS Design GuRu Methodology proves to be effective in supporting the generation, management, use, sharing, and reuse of new knowledge in the shape of design guidelines and rules.

Composting of byproducts from the orange (Citrus sinensis (L.) Osbeck) and sugarcane (Saccharum spp. hybrids) agroindustries

There is a global problem involving the generation, management, disposal, and treatment of agro-industrial waste, since it requires technologies for its transformation into the sustainable production of food, fodder, biofuels, fibers, bioproducts, and biofertilizers. The citrus and sugarcane agroindustries generate waste or byproducts that require a special treatment to be reused. Sugarcane byproducts already have an established but unsustainable use. In the case of citrus fruits, 50-60% of the organic waste has an acidic pH (3-4), 95% organic matter, and 80-90% moisture. The objective of this research was to evaluate and model the pile composting method applied to byproducts of the orange and sugarcane agroindustries to obtain compost with competitive physicochemical parameters for use as a soil improver. The pile was designed with a pyramidal rectangular arrangement, and 9 points were established for temperature sampling in three different sections during composting. An average of 55 °C and a pH of 9,1 were obtained at the end of the process. Compared to the regional control, the C/N ratio (27,5), organic matter (65,5%), and macro- and microelements show improved characteristics for use in food production in agroecological agriculture.

The Impact of New Generation Management Approaches on the Firm Performance: The Moderating Role of Strategic Human Resource Management Applications

The main purpose of this study is to research how and to what degree a company’s performance is affected by the new generation management approaches through strategic human resource applications. Within this framework, of the new generation management approaches, organizational ambidexterity, learning organization, and innovation capability have been included as independent variables, and of the strategic human resource applications, with the moderation of talent management and the recruitment and selection process, the effects on firm performance have been tested empirically. The study was conducted in 2018 by evaluating 387 of the questionnaires collected from the firm owners and middle and upper management of randomly selected large and mid-sized businesses in Istanbul, Ankara, Bursa, and Izmir. The collected data were tested using SPSS and, within the scope of structural equation modeling, using SmartPLS. At the conclusion of the research, of the new generation management approaches, it became evident that innovation capabilities have positive effects on the firm performance and that the learning organization also has positive effects on the firm performance by the effect of the moderating variables. Furthermore, a striking weakness was found in the relationship between the performance of a firm and innovation ambidexterity. It was also found that talent management plays no moderating role in the effects of new generation management approaches on the firm performance.

Effect of Information Architecture on the Usability of a University Website

A well-planned information architecture (IA) of a website can enhance the end users' efficiency, learnability, controllability and intention to revisit the site. Its significance is even more in the context of academic websites where the generation, management, and distribution of information are among the major activities. However, it remains a neglected issue as designers of academic websites have overlooked the important aspect of ‘intuitive user navigation' and focused primarily on its ‘look and feel.' Thus, the current study aims to analyze and compare the effectiveness of information architectural designs of some randomly selected university websites of Punjab (India) through a usability testing technique. For this purpose, the performance metric measured was the information seeking time. The usability session of each subject was captured through Camtasia Studio software. The findings of this study highlight the shortcomings of presently designed academic websites which adversely affect the usability of a website.

Retention of Generation Y in Hungarian Public Servic

The article discusses challenges of retaining young people in public service. Is it possible to have a new generation of public servants, who choose this profession even for a lifetime? In search of the answer literature of generation theories, generation management and retention management is reviewed and influencing factors of a generation membership and retention are synthesized. Empirical research results of a survey with over 1300 responders among Hungarian public servants are shown from which an identity profile of Generation Y public servants is sketched and proposals are made for long-term retention strategies. Outcome of the research suggests generational approach to be introduced in public service human resource management in order to support more effective retention management and to better understand possible generational differences instead of relying on false assumptions.
