Consecutive Time

We introduce successive committees elections. The point is that our new model additionally takes into account that “committee members” shall have a short term of office possibly over a consecutive time period (e.g., to limit the influence of elitist power cartels or to keep the social costs of overloading committees as small as possible) but at the same time overly frequent elections are to be avoided (e.g., for the sake of long-term planning). Thus, given voter preferences over a set of candidates, a desired committee size, a number of committees to be elected, and an upper bound on the number of committees that each candidate can participate in, the goal is to find a “best possible” series of committees representing the electorate. We show a sharp complexity dichotomy between computing series of committees of size at most two (mostly in polynomial time) and of committees of size at least three (mostly NP-hard). Depending on the voting rule, however, even for larger committee sizes we can spot some tractable cases.

Distribution Theorem

Consider any discrete time sequence of investment fortunes Fn which has a finite long-run growth rate [Formula: see text] when subject to the present value capital drawdown constraint Fne-rn ≥ λ* max 0≤k≤nFke-rk, where 0 ≤ λ* < 1, in the presence of a riskless asset affording a return of er dollars per time period per dollar invested. We show that money can be withdrawn for consumption from the invested capital without either reducing the long-run growth rate of such capital or violating the drawdown constraint for our capital sequence, while simultaneously increasing the amount of capital withdrawn for consumption at the identical long-term rate of V(r, λ*). We extend this result to an exponentially increasing number of consumption categories and discuss how additional yearly contributions can temporarily augment the total capital under management. In addition, we assess the short-term practicality of creating such an endowment/consumption/distribution program.

Air Disaster

The aim of this article is to examine the social and psychological impact of modern maritime disasters upon the population of a technologically developed nation. Through an innovative research approach using various indirect measurements of public interest including the internet, media response, music and film, the article explores the interest displayed by the American public following the loss of ships such as the Titanic, Andrea Doria, Edmund Fitzgerald, and Andrea Gail. In order to provide a basis for qualitative comparison, disasters involving other modes of transportation are also considered, including the Hindenburg crash, the ‘Great Train Wreck of 1918’ in Nashville, TN, the Tenerife air disaster of 1977, and the Concorde crash of 2000. The article seeks to explain why the American public seems to display more short-term and long-term interest in maritime disasters than in disasters involving other forms of transportation.

Movements and parties have given rise to two largely separates specialties in the social sciences. This Element is an effort to link the two literatures, using evidence from American political development. It identifies five relational mechanisms governing movement/party relations: two of them short term, two intermediate term, and one long-term. It closes with a reflection on the role of movement/party relations in democratization and for democratic resilience.

Abstract. In compliance with the development of the Water Framework Directive, there is a need for an integrated management of water resources, which involves the elaboration of reservoir management models. These models should include the operational and technical aspects which allow us to forecast an optimal management in the short term, besides the factors that may affect the volume of water stored in the medium and long term. The climate fluctuations of the water cycle that affect the reservoir watershed should be considered, as well as the social and economic aspects of the area. This paper shows the development of a management model for Rules reservoir (southern Spain), through which the water supply is regulated based on set criteria, in a sustainable way with existing commitments downstream, with the supply capacity being well established depending on demand, and the probability of failure when the operating requirements are not fulfilled. The results obtained allowed us: to find out the reservoir response at different time scales, to introduce an uncertainty analysis and to demonstrate the potential of the methodology proposed here as a tool for decision making.

In the management science, there is a level whereas it is called social responsibility or it is just social obligation. Many opinions argues that CSR program will reduce the profit of the respected company. But many opinions denies the previous argue by saying the CSR program is a long term program profit gain since the short term result is good public image. The good public image will lead the loyalti of customer to keep using the product or service from the hotel. The customer loyalti also affected by the customer’s opinion, if they involves in the social activities held by the hotel, they also participate in a social activity.

<p><em>In addition to the well-known classification of long-term and short-term memory, we are also interested in distinguishing episodic, semantic and procedural memory in the areas of linguistic narrative and multimedial semantic deconstruction in postmodernism. We compare the liveliness of memorization in literary tradition and literature art with postmodernist divisions and reverberations of traditional memorizations through human multitasking and performative multimedia art, as well as formulate the existence of creative, intuitive and superhuman paradigms.</em></p><em>Since the memory can be physical, psychological or spiritual, according to neurobiologist Dr. J. Bauer (Das Gedächtnis des Körpers, 2004), the greatest importance for memorizing has the social role of collaboration, and consequently the personal transformation and remodelling of genomic architecture, yet the media theorist Mark Hansen thinks technology brings different solutions of framing function (Hansen, 2000). We believe that postmodern deconstruction does not necessarily damage memory, especially in the field of human multitasking that utilizes multimedia performative art by means of anthropologization of technology, thereby enhancing artistic and affective pre&amp;post-linguistic experience while unifying technology and humans through intuitive empathy in society.</em>

The study aimed to identify the influence of the financing structure on the return of the market share in Saudi corporations/companies. The study applied the descriptive-analytical approach, and the study population consisted of some joint-stock companies in the Saudi stock market, where the study sample consisted of (75) companies in five productive sectors where concentration was made on the following sectors: (basic materials, long-term commodities, energy, food production, capital goods). Method of the comprehensive survey was used for all companies. The data was analyzed using the Panel Data method through the STATA program. The study concluded several findings, the most important of which are that short-term debt (liabilities) have a negative impact on the return on the market share, as increasing short debts (liabilities) lead to a decrease in the return on the market share, and that long-term debt (liabilities) have no effect on the return on the market share, and equity has a negative impact on the return on the market share, as the increase in financing through equity leads to a decrease in the return on the market share. The study recommended the necessity of diversification between sources of financing and not limited to debt and long & short-term liabilities only. It also recommended conducting such a study on other sectors or conducting it on the whole market which may result in improving results, and also recommends expanding the time period more than five years, which may lead to improve results.

AbstractWe discuss the implications of the new public governance and its impact on the social and economic outcomes of those experiencing poverty. As members of civil society, religious congregations are actively engaged in supporting people living in poverty with short-term responses. Addressing the societal focus on economic justice and the theological traditions of four world religions, this paper seeks to encourage religious congregations into innovative, actionable responses that help to offer long-term responses that align with poverty alleviation. We propose two approaches—community development and financial development— that serve as models for religious congregations interested in alleviating poverty.

A great deal of research has been performed recently on robots that feature functions for communicating with humans in daily life, i.e., communication robots. We consider it important to develop methods to measure humans’ attitudes and emotions that may prevent them from interaction with communication robots, as indices to study short-term and long-term interaction between humans and communication robots. This study is aimed at exploring the influence of negative attitudes toward robots, focusing on applications of communication robots to daily-life services. First, a scale of negative attitudes toward robots consisting of three subordinate scales, “negative attitudes toward situations of interaction with robots,” “negative attitudes toward the social influence of robots,” and “negative attitudes toward emotions in interaction with robots,” was developed based on a data sample comprising of 263 Japanese university students. This scale was administered to 240 Japanese university students to confirm its validity and reliability. In this paper, we report on the results of analyses of these data samples. Moreover, we discuss some future problems including a comparison of attitudes toward robots between nations.

Social Work Interventions

Human trafficking victims require holistic and long-term services if their social conditions are to be improved. This study aims to explore the nature of social work services for human trafficking survivors. Semi-structured interviews were conducted with a cohort of social workers in a statutory anti-trafficking organization in southern Nigeria and the results were analyzed using thematic analysis. While the social workers reported providing services to trafficking survivors, these services were mainly rehabilitation-driven and short-term-focused. Although the research relates to a small-scale study, it has far-reaching implications for social work professionals and the Nigerian political leadership.
