The Current Context and Future Trends of the Photovoltaic Business Models in Central and Eastern Europe:Case Study—Romania

引用

Smart Grid and Renewable Energy 2014年第3期5卷 43-51页

作者： Adrian Dumitru Tantau Maria Alexandra Nichifor Horatiu Regneala Faculty of Business Administration Bucharest University of Economic StudiesBucharestRomania

The evolution of the PV industry has represented one of the main focus points of economic and political debates and research of the last ten years in Europe. However, these discussions have only presented general aspects of the industry development and accomplishments with little information about the companies’ actual practices. The present study aims to inquire the PV field in Romania further, by researching the currently implemented and the future business models of firms producing solar energy. Using the Delphi method based on questionnaires and interviews with experts of this field, this paper shows the key elements of business models in the PV field that reflect the companies’ practices and future trends and expectations regarding the internal activity of the firm and the environmental changes from the external environment of the company, which influence the directions of the PV domain. The relevance of this study is based on the importance of the applied PV business model elements in order to ensure the survival and expansion of the company in a dynamic field that faces continuous legal, economic and technological changes and challenges. The results of this study have some directions that could be applied in most of the European countries where the PV industry is developing.

In Central African Republic, edible caterpillars of Imbrasia gender are income of rural populations, present an opportunity to improve food security and belonging to the category of Non-wood forest products. The goal of this study is to document the ecology of caterpillars of genre Imbrasia in relation to its host plants in Boukoko. The questionnaire was addressed to the actors of the collection and consumption of caterpillars in this Commune, to their local knowledge concerning this food resource as well as the plants of their locality on which caterpillars are collected. The survey took place in September to October 2022 and as a general rule, the 120 respondents were elderly people whose age range varied from 35 to 70 years old. Plant samples are collected in their natural environment. Based on local names;herbaria are mounted, plants photographed and samples collected. The types of edible caterpillars have been inventoried in the field in collaboration with the local populations who consume them. Based on local names, the caterpillars are captured manually from morphological traits and then stored in bottles containing 70% ethanol. The specimens were identified. The data was entered into the Excel spreadsheet which also made it possible to produce histograms with the frequencies of the plant species most valued by the different caterpillars. A Principal Component Analysis (PCA) was then performed using R software to highlight the correlation between caterpillars and host plants. The main economic importance trees hosting edible caterpillars of Imbrasia gender in Boukoko region are: Entandrophragma cylindricum, Pentaclethra macrophylla, Maesopsis eminii, Albizia ferruginea, Macaranga spinosa, Amphimas ferrugineus, Pentaclethra macrophylla, Racosperma auriculiforme, Eribroma oblonga. The Principal Component Analysis (PCA) carried out to assess the variability between the different species of caterpillars according to their host plants shows that the first two axes

Organizational Data Management： Proposing a Metadata-Driven Data Warehouse （DW） Model

引用

Journal of Modern Accounting and Auditing 2012年第12期8卷 1898-1905页

作者： Cezar Liviu Cervinschi Diana Butucea Academy of economic studies Bucharest Romania

Discussing the matter of organizational data management implies, almost automatically, the concept of data warehousing as one of the most important parts of decision support system (DSS), as it supports the integration of information management by aggregating all data formats and provisioning external systems with consistent data content and flows, together with the metadata concept, as one of the easiest ways of integration for software and database systems. Since organizational data management uses the metadata channel for creating a bi-directional flow, when correctly managed, metadata can save both time and resources for organizations. This paper1 will focus on providing theoretical aspects of the two concepts, together with a short brief over a proposed model of design for an organizational management tool.

Risks in Credit Financial Analyze

引用

economics World 2014年第5期2卷 303-309页

作者： Liviu Adrian Stoica Academy of economic studies Bucharest Romania

This article aims to study the indicators used in the financial analysis for credit and explain them. Also it checks the impact of each indicator in credit analysis and what happens if the pointer is changed deliberately to get the loan, giving some possible ways to do it and analyzing them. It proposes a new model to evaluate the indicators and the assignment of weights in formula evaluation of each indicator, so the risks of granting credit will be smaller as well as the evaluation of the financial terms of a company will be more balanced and optimal. The scope is to equilibrate the weights of each indicator in the financial credit analyze not by rescoring its value but by assigning shares in the evaluation formula. Doing this, it can be considered as a double checking using the same parameters and it lowers the risks in the money recovering. As it is debated in the article anyone can do fraud to obtain a loan by altering the documents they provide through which some can do it good and even get uncaught. The scope is not to find what they did; it is to get protected even if they do it.
