Electronic commerce, marketing on line, and network economy are today’s keywords of (possible) success. But how many managers effectively know about the cost and benefits of starting to sell their products and services through the Web? How much they should invest at the beginning and how long does it takes to have a break-even point of their investment? In order to give support for better understanding the process of the Web marketing and to have more elements to decide to “dive” or not in this virtual world a System Dynamics (SD) model (Forrester J.W. 1961, 1971, 1980), has been developed. The model has the aim to support strategic decisions for SME involvement in e-Commerce, pointed out to guarantee sustainable growth and medium-long term success. The project e-Impresa1 analyses the whole process of the investment in building and maintaining a web site, taking into account the main variables of E-commerce. Through a case study, a SD business game model has been developed. The model gives the opportunity to users to evaluate different what-if analysis through the simulation period time (2 years) at each model step time (4 weeks). This chapter will explain the overall architecture of the model and will present some results of use of the model in different conditions.

The use of anti-forensic techniques is a very common practice that stealthy adversaries may deploy to minimise their traces and make the investigation of an incident harder by evading detection and attribution. In this paper, we study the interaction between a cyber forensic Investigator and a strategic Attacker using a game-theoretic framework. This is based on a Bayesian game of incomplete information played on a multi-host cyber forensics investigation graph of actions traversed by both players. The edges of the graph represent players’ actions across different hosts in a network. In alignment with the concept of Bayesian games, we define two Attacker types to represent their ability of deploying anti-forensic techniques to conceal their activities. In this way, our model allows the Investigator to identify the optimal investigating policy taking into consideration the cost and impact of the available actions, while coping with the uncertainty of the Attacker’s type and strategic decisions. To evaluate our model, we construct a realistic case study based on threat reports and data extracted from the MITRE ATT&CK STIX repository, Common Vulnerability Scoring System (CVSS), and interviews with cyber-security practitioners. We use the case study to compare the performance of the proposed method against two other investigative methods and three different types of Attackers.

Harvest activities tend often to create landscapes where the old forest is fragmented into isolated patches that provide marginal conditions for species that inhabit forest interiors. This paper presents a long-range planning model designed to maximize the net present value and to create continuous patches of old forest. In this model, the spatial structure of old forest is controlled by core area and edge habitats. Core area is defined as the area of old forest that is free of edge effects from surrounding habitats. The core area requirement is set to a fixed value for each of a number of time periods, whereas the area of edge habitats, which should be as small as possible, is weighted against the net present value. The model is applied in a case study to an actual landscape consisting of 755 stands of forest in northern Sweden and solved using simulated annealing. The results show that distinct continuous patches of old forest are created when both a core area requirement and consideration of the amount of edge habitats are included in the problem formulation. The cost of creating continuous areas of old forest was found to be significant.

Everyone talks about corporate social responsibility when there is discussion on the profitability issue. As the society is the major stakeholder in any corporate, it is natural duty of the concerned company to full fill its responsibility towards the society. There are many issues which can be included in the corporate social responsibility but the question arise is that what will happen if a company don't focus on sustainability. The obvious answer is that without sustainability, the fulfilment of certain types of social responsibility activities by the company will not provide the true advantage of the CSR to the society. It can be put in this way that at the cost of long term benefits of the society, the short term benefits are provided if sustainability is sacrificed. The future generation will cry like anything for the loss we are making today. This paper is aimed to discuss the Corporate Sustainability Reporting through case study of Tata Consultancy Services (TCS).

Radio Planning

Transitioning a Terrestrial Trunked Radio (TETRA) network to a Long-Term Evolution (LTE) network in public protection and disaster relief (PPDR) systems is a path to providing future services requiring high radio interface throughput and allowing broadband PPDR (BB-PPDR) radio communications. Users of TETRA networks are currently considering how to deploy a BB-PPDR network in the coming years. This study offers several radio planning considerations in TETRA to LTE migration for such networks. The conclusions are obtained from a case study in which both measurements and radioelectric coverage simulations were carried out for the real scenario of the Murcia Region, Spain, for both TETRA and LTE systems. The proposed considerations can help PPDR agencies efficiently estimate the cost of converting a TETRA network to an LTE network. Uniquely in this study, the total area is divided into geographical areas of interest that are defined as administrative divisions (region, municipal areas, etc.). The analysis was carried out using a radio planning tool based on a geographic information system and the measurements have been used to tune the propagation models. According to the real scenario considered, the number of sites needed in the LTE network—for a specific quality of service (90% for the whole region and 85% for municipal areas)—is a factor of 2.4 higher than for TETRA network.

Considering the recent lockdowns and travel bans due to COVID-19, novel tourism strategies are necessary to face the increasing need for innovative products and services and to ensure long-term sustainable growth. This study looks into the potential use of drones in providing online virtual tours of open-space tourist attractions. To do so, a novel mixed-integer linear mathematical model is developed to optimally determine the number and location of required facilities and the number of drones assigned to each center. The model is applied to a case study of Rome by selecting six historic sites as the tourist attractions and considering several candidate locations for establishing the facilities. The results of different potential scenarios imply that the project is profitable, even if the demand for virtual tours is low.

In modern conditions for Kazakhstan, it becomes important to choose a development model that would be the most optimal and effective. When developing a model of economic policy, special attention should be paid to the choice of a system of indicators that could adequately describe macroeconomic processes as a whole and their interconnections. At the same time, economists argue that the implementation of the model approach can become the basis for strategic decisions only in a stable economic situation and when in the period under review the change in the cost structure of GDP is not distorted by high inflation. Therefore, in modern conditions of economic development, in our opinion, it is of interest to study the relationship between economic growth and the level of current and threshold inflation. This study substantiates the role of the threshold inflation level and proposes an equation of the functional dependence of this indicator on the main economic indicators. The necessary conditions for the implementation of the inflation targeting regime are disclosed. It is concluded that in conditions of commodity dependence, new effective monetary policy instruments are required.

AbstractLakes, rivers, estuaries and ocean waters control many important natural functions at the regional-global level. Hence, integrative and frequent long-term water monitoring is required globally. This paper describes the main features and innovations of a low-cost monitoring buoys network (MBN) deployed in a temperate region of Argentina. The MBN was designed to record extended time series at high-frequency, which is of great value for the scientific community, as well as for decision-makers. In addition, two innovative designs belonging to two versions of moored buoys (i.e. shallow waters and coastal marine waters) were presented. It was shown that the cost of either of two versions of the buoy is low, which can be considered as the main advantage.

Museum Practice

<p>In the current economic climate museums are increasingly being asked to do more with less. For museums that hold collections, this poses a unique challenge. With the cost of collections being relentlessly accumulative, questions are being raised about the long term financial sustainability of current collecting practices. Deaccessioning is being suggested as a way in which museums can improve the quality of their collection without increasing its size. Yet the literature on deaccessioning suggests that the process is fraught with ethical and practical difficulties. By highlighting the negatives aspects of the process, writing in museum studies and practice does little to explore how deaccessioning might be used to achieve positive outcomes. This research addresses this gap by asking whether deaccessioning is a positive tool that, if used appropriately, can assist a museum in improving the quality and manageability of their collection through systematic planning. To understand how and why a museum may permanently remove objects from their collection, the study focuses on one New Zealand museum’s response to the challenge of redeveloping a collection through the process of deaccessioning and disposal. The Museum of Wellington City and Sea’s deaccessioning process is analysed through documentary research and interviews with Museum staff. The interviews offer an understanding of the thought processes and motivations involved in selecting objects to be deaccessioned. The data collected reveals both the challenging aspects of the process but also offers insights into how these aspects can be mitigated or resolved. The conclusions presented in this dissertation suggest that deaccessioning is an integral part of current museum practice that can be used positively to actively shape and refine a museum collection. I argue that some of the beneficial outcomes of the process include greater understanding of collections, improved knowledge and context, resolution of historical collecting problems, strategic relationships built with other museums and improvement in how objects are stored and utilised. More importantly deaccessioning allows museums to determine the character and content of their collections. In order for this to be achieved, I recommend that museums adopt a rational approach to reviewing their collections that is multi-disciplinary, transparent and acknowledges how their collection is used in the achievement of their institution’s mission.</p>
