The present study focuses on a new approach in the process of developing personal work styles, based on the usefulness of 360 degree feedback, taking into consideration the following dimensions: work-life balance, gender-age, self-development and the behavior a person has, following the process of self-development and defining work style. Using different approaches, the study attempts to identify if there are some differences between the evaluations received from the family and the ones from the work environment. All these factors aim at improving personal, but also organizational performances. Based on the current body of the literature, a discussion is made and conclusions are presented.
Energy security is a constant presence in the energy-related political discourse all over the world. States strive to secure steady inflows of needed energy supplies, as well as the price affordability of those supplies. However, what are deemed to be the best means to meet such goals depends on one’s theoretical vantage point. On the one hand, economically-minded theorists maintain that energy security is only a matter of market rules and interactions. Thus, they call upon energy markets to deliver both steady supplies and competitive prices. On the other hand, politically-minded scholars emphasize the political and hard-power nature of international energy trades, especially in a global context market by the emergence of state-centered, authoritarian regimes that use large national energy companies as foreign policy instruments. These two positions delineate competing approaches to how energy security risks ought to be managed. The former approaches energy security risks by means similar to portfolio management, requiring diversification of investments in order to insulate them from market shocks. The latter approaches energy security as a matter of foreign policy, by which states envisage interest coordination and favorable alignments within countervailing alliances against the agent of energy security risk. The present paper goes beyond the uncontentious point that these two dimensions are complementary. It argues that, depending on the international context, a more market-driven or a more-politically driven behavior may be adequate.
The current volatile economic environment and the evermore shorter technology cycles impact the way business is done today, especially in an emerging field like the renewable energy sector. Business modelling proves itself as an instrument, which may impact decisively the success or failure of a business. The aim of this article is to identify and present the key elements defining entrepreneurial models in the renewable energy field, as resulted from a synthesis of the recent literature available in journals indexed in international databases of mainstream publications about business models and entrepreneurial models as well as from empirical research performed in the past five years. The research result consists in a systematisation on past approaches on business modelling and the development and adaptation of the entrepreneurial model’s definition specific for the biogas sector.
The Romanian natural gas market is still in its infancy regarding the manners in which the demand and supply match. We are frequently talking about market liquidity or about its dynamic behavior, without considering the monthly losses of the national natural gas system operator that derive from the very lack of matching the supply and demand. The present article proposes a method of overlaying the two in a manner that is feasible for the Romanian natural gas market of 2017, a method that will encapsulate the usage of OBAs (operational balancing agreements) in correlation with a model of allocating the demand and supply as a restricted all-pairs shortest path problem. Based on authors experience, five main variables will be examined: point-of-entry (location and time), volume, time and location of delivery, as well as other sets of data that are particular to this sector. This article will tackle the area of usability of OBAs between suppliers and the degrees of sustainability that such a model offers for clients, therefore the resilience of the system will be analyzed through an optimized transfer of information and accessibility to assets. Due to the complex nature of demand in energy markets and the different requirements set by clients, in which an energy resource can be requested by different sets of users, we will conceive a model that can be applied for natural gas, but also for electric energy production and industrial clients. The scope of this endeavor is to create a tool that will minimize the monthly losses of the national natural gas system operator, as well as its distributors, by allocating, in a fair and unbiased way, the responsibility of fulfilling the requested demand in a certain time unit.
