When two complementary firms with heterogeneous assets are both breached, it is assumed that they suffer different losses which are associated with their information assets. Some insights about optimal strategies for the firms and the attacker are obtained by the game theory, which forms a comparison with those derived from substitutable firms, and those derived from complementary firms with homogenous loss. In addition, both the unit transform cost of investment and the extent of firms＇loss affect the optimal strategies.Assuming that firms can control information sharing, security investments and both of them, respectively, the effect of the social planner is further analyzed on the information sharing, firms＇ aggregate defence, the aggregate attack and social total cost. Finally, some policy advice is provided through numerical simulation. Results show that firms are willing to choose security investment centrally rather than individually, but an intervention in information sharing by the social planner may not necessarily be preferable.展开更多

The main objective of this study was to compare the projected and the real ROI （return on investment）, after seven years of use. ROI was calculated annually （from 2008 to 2015）, by deducting the cost of investment （ADS buying and implementation, maintenance, repairs and ADS upgrade） from the cost saving （drugs stock reduction and decrease of pharmacy staff dedicated to global dispensing）. In 2015, total costs saving （＋$1,141,987） were divided between decreasing drug stock value and reduction of pharmacy staff. Total costs of investment （-$978,656） were acquisition, maintenance, repairs and an unplanned upgrade costs. Finally, the real ROI was ＋$163,331 after seven years of use. In 2008, projected ROI was ＋$410,786. The real payback period has been increased by approximately two years （six years of use, instead of four years as expected）. Despite their cost, ADSs are a worthwhile investment, leading to a ROI within a few years. These economic considerations should be put into perspective with optimization of drugs stock management, greater efficiency of the global dispensing process, securitization of medication process and redeployment of pharmacy staff.展开更多

Moreover, all Municipalities are quite different considering specific characteristics, such as geographic, demographic, and economic. The aim of this research is to separate the entire sample of Municipalities in Greece into categories, based on the effectiveness of financial management and financial performance into effective and ineffective ones. For the separation of the sample into groups, cluster analysis was preferred. For this reason, three variables were used： the lending capacity of the Municipality, flexibility in making non-investment costs, and flexibility in investment spending. These three variables were considered to be the key dimensions of effectiveness in financial management and therefore their use, representatively describes the effectiveness of Greek Municipalities. Thus, this paper presents the literature review of the financial effectiveness of Municipalities and the methodology of an empirical research through structured questionnaire that was sent to the entire population of Greek Municipalities, characterized in this way with considerable heterogeneity. In this way, it investigates the views of Mayors in the two categories of Municipalities （effective and non effective financial management and financial performance） as regards： （a） the biggest problems faced by the citizens in their Municipality, and （b） the biggest personnel problems faced by their Municipality. Concluding, the prioritization of both problems seems to be the same for both groups of Municipalities. The frequency of responses differs slightly and differences are not so large that financial performance can be considered to affect respondents＇ opinions.展开更多

In the meantime, it reveals the football field＇s quality effects in the performance at the national championships, at television transmission rights, and sale of football players to foreign clubs. In addition, the dynamics of investment in the last two decades and the Albanian Football Federation objectives for the future are an important part of this article展开更多

Training is an important part of the enterprise human resources management. For enterprises is a kind of novel important human capital investment, as well as other capital investments, both benefits. Also be risky, because of the risks and benefits is coexistence, indivisible. To deal with the mentioned challenge, we combine the novel and state-of-the-art training methodology to maximize the effectiveness of the training process. In the article, we cast our new opinion together with the prospect for the future.展开更多
