Wives’ Work Hours and Marital Dissolution: Differential Effects across Marital Duration  [PDF]

Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.21002
Abstract: In this article, I ask: Does the effect of wives’ work hours on marital dissolution change across marital duration? Using the first two waves of the National Survey of Families and Households (NSFH), I find only weak evidence that wives’ work hours are associated with higher marital dissolution. The effect, however, is more positive and significant among long-term marriages. In addition, this study also tests whether couples’ gender ideology and marital interaction explain this differential effect of wives’ work hours. The results suggest that couples’ gender ideology does not account for this differential effect of wives’ work hours. The more positive effect among long-term marriages, however, is reduced to insignificance as soon as a marital interaction measure is introduced into the model. This study contributes to broader research in two ways. Despite the weak effect of wives’ work hours on marital dissolution, the buffering effect of marital duration challenges the prior assumption that the effect of wives’ work hours is invariant across marital duration. Second, this study suggests that the more positive effect of wives’ work hours on marital dissolution among long-term marriages can be attributed to couples’ marital interaction in these marriages becoming more important in mediating the effect of wives’ work hours. Given these results, this study suggests that future research should consider the buffering effect of marital duration in understanding the determinants of marital dissolution.
Revisiting Company Law with the Advent of Ethiopia Commodity Exchange (ECX): An Overview

Mizan Law Review , 2010,
Abstract: The historical development of the law of companies shows that this area of the law is evolving and continually changing based on the level of economic development. The law directly dealing with companies, the 1960 Commercial Code of Ethiopia, seems to limit the scope of the law of companies only to private limited companies and share companies, save the partnerships included in the Code. This is a very narrow approach as it leaves out public enterprises simply because they are not recognized under the Code. This article examines the salient features of company law and argues in favour of a broader understanding of the concept. As such, the article vets the main features of private limited companies, share companies, public enterprises and The Ethiopia Commodity Exchange) ECX and shows how the advent of the ECX has challenged the frontiers of the existing legal framework of Ethiopian law of companies. The study argues that ECX is a unique “hybrid-model” which can neither be categorized as a registered company nor as a public enterprise (statutory company) thereby enhancing the challenge to the frontiers of company law as envisaged in the 1960 Commercial Code of Ethiopia.

JISTEM - Journal of Information Systems and Technology Management , 2008,
Abstract: This research proposes to define models for information management to guide the commercial action of a small IT company. The focus on small companies occurs due to the high percentage of companies with this profile in the IT sector. A set of models for information management was proposed, implemented and used during the daily commercial activities. The practical experience is detailed based on the evaluation of ease, comprehension and use. Action research was chosen as a methodology for this study because there was interest and availability of the company to put into practise the new set of models that was proposed. The company reacted positively do the models that were implemented, in terms of acceptance and in terms of comprehension, ease of use and utility. The company considered that, after using the models, there were better conditions of handling the information, and, therefore, it became possible to guide the commercial action in a more dynamic way.

Abstract: The ratios between the main frequency of rotating stall and rotational frequency may be considered in the form of exact ratios of small natural numbers if the pressure signals in compressors during rotating stall include the rotor rotation frequency component. During rotating stall in compressors with good rotor balancing (with absence of the rotational frequency component in the frequency characteristics of pressure signals), these ratios between the main frequency of rotating stall and rotational frequency are or are not in the form of ratios of small natural numbers. The experimentally received characteristics of power spectral density of pressure signals also show the presence of components with combinations of blade passing frequency and different harmonics of main rotating stall frequency. 1. Introduction Rotating stall is an undesirable and even dangerous oscillatory process in a compressor. Its important characteristic is that the phase of fluctuations of pressure on a compressor circle changes in any cross-section depending on the angle of sensor positions (see, e.g., Moore and Greitzer, 1986 [1], Greitzer and Moore, 1986, [2], Longley, 1994 and 2007, [3, 4], Day and Freeman, 1994 [5], Camp and Day, 1998, [6], Day et al., 1999, [7], Bright et al., 1999, [8], Inoue et al., 2002, [9], Bergner et al., 2006, [10], etc.). Three basic frequencies can be found in a compressor during an established rotating stall process and at its inception: the main frequency of rotating stall, the frequency of rotor rotation, and the blade passing frequency. Besides these, there can be their harmonics and also frequencies representing combinations of these three frequencies and their harmonics. The physical nature of all these frequencies is absolutely different. (i)Main (basic) frequency of rotating stall is caused by dynamic characteristics of the compressor and the gas system in which the compressor is included. (ii)Existence of components with rotational frequency is caused by mechanical reasons (nonideal geometrical sizes of blades, non-ideal balance of disks and blades of the rotor, shift of the axis of rotor rotation concerning the stator axis, etc.). (iii)Occurrence of pressure fluctuations with blade passing frequency is caused by the gas flow crossing the compressor rotor blades during rotation. These components exist even when compressor balance is ideal. The two first frequencies are frequencies of about one order; they are usually considered and analyzed in common. Blade passing frequency (being a product of the rotor rotation frequency and the number
The private sector’s contribution to water management: Re-examining corporate purposes and company roles
Peter Newborne,Nathaniel Mason
Water Alternatives , 2012,
Abstract: Corporate water policies are evolving and practices developing, raising issues of what are appropriate private-sector roles in water management. Leaders of multinational companies have pledged to increase water use efficiencies in company plants/premises and down supply chains, while promoting partnerships in water management with a range of actors, public and private, including local communities. A set of questions is, here, posed for consideration by governments and communities, on the extent, limits and implications of private-sector involvement, particularly in contexts of water scarcity. While water specialists are accustomed to analysis of mandates of public institutions, many are much less familiar with the internal workings of corporations. Companies are legal and social constructs, operating within frameworks of company law and codes of stock exchanges. These set the normative parameters of what each company is for, and for whom, and help explain the underlying motivations and priorities of each. To illustrate corporate purposes and degrees of responsiveness to different stakeholders, example company models are cited. Company statements mixing commercial and philanthropic messages risk confusing company roles. Corporate actions need to match companies’ internal characteristics to 'do what it says on the inside of the corporate tin'. Partnerships can, potentially, offer an alternative normative framework for achieving sustainable and inclusive growth.

CES Working Papers , 2012,
Abstract: All stakeholders are interested in whether a firm has a good and stable financial situation, even though they all have different stakes in it. However, not all companies can succeed and operate profitably. The purpose of the study is to examine the peculiarities of dissolution and liquidation in Romania and the characteristics of liquidation of companies, according to their legal form. From examining the general causes of dissolution to specifics of different type of companies, all elements have a great importance in understanding how to avoid this procedure.
Automation of dissolution tests  [PDF]

Abstract: Dissolution testing of drug formulations was introduced in the 1960s and accepted by health regulatory authorities in the 1970s. Since then, the importance of dissolution has grown rapidly as have the number of tests and demands in quality-control laboratories. Recent research works lead to the development of in-vitro dissolution tests as replacements for human and animal bioequivalence studies. For many years, a lot of time and effort has been invested in automation of dissolution tests. There have been a number of in-house solutions from pharmaceutical companies and many have created task forces or even departments to develop automation. Robotic solutions with sequential operation were introduced as well as the simultaneous operation concept developed by SOTAX. Today, pharmaceutical companies focus their resources mainly on the core business and in-house engineering solutions that are very difficult to justify. Therefore, it is important to know the basic considerations in order to plan an automation concept and implement it together with a vendor.

Abstract: The field of quality is very important for a company under current conditions. It is necessary to continuously improve the quality of provided services. Even though metallurgy is focused on production, not on providing services, even in these companies great variety of services exists, which is important to improve all the time. One of these production supporting services are the repairs. This article analyses and solves the problem of insufficient promptness of the repairs in a metallurgy company.

Abstract: O presente trabalho visa analisar a responsabilidade tributária e a data de início da prescri o para a Fazenda Pública requerer o redirecionamento da execu o fiscal contra os sócios-gerentes da sociedade por cota de responsabilidade limitada no caso de dissolu o irregular da sociedade. O desenvolvimento do trabalho pauta-se em pesquisa doutrinária e jurisprudencial e busca evidenciar os aspectos jurídico, ético e econ mico que cercam a responsabilidade do sócio pelas dívidas tributárias da sociedade. Parte-se do significado jurídico-tributário do termo "responsabilidade", analisam-se as regras e as exce es relativas à responsabilidade dos sócios pelas obriga es sociais, mediante o exame da responsabilidade subsidiária, solidária e pessoal, bem como da responsabilidade limitada e ilimitada dos sócios pelas obriga es da sociedade. Chega-se ao fundamento jurídico da responsabiliza o pessoal e ilimitada dos sócios pela dissolu o irregular da sociedade e ao fundamento jurídico da exce o à regra que fixa o início do prazo de prescri o para que a Fazenda Pública requeira o redirecionamento da execu o fiscal contra o sócio responsável pela dissolu o irregular da sociedade. A conclus o evidencia recente orienta o jurisprudencial que, em situa o excepcional, afasta a regra legal que determina seja iniciado o prazo de prescri o a partir da constitui o definitiva do crédito tributário. PALAVRAS-CHAVE: Responsabilidade pessoal. Sócio-gerente. Dissolu o Irregular. Prescri o. ABSTRACT: This essay aims to analyze the tax liability and the initial date of prescription in which the Public Treasury can require the redirection of the tax foreclosure against the managing partners of a company per share of limited responsibility in case of an irregular dissolution of a society. The development of the essay is based on jurisprudence and doctrinal research and seeks to show the legal, ethical and economic aspects that surround the shareholder’s responsibility for the tax debts of a company. It begins with the legal meaning of the term “responsibility”, then exams the rules and exceptions related to the secondary, mutual and personal responsibilities, as well as the limited and unlimited liability of shareholders for the obligations of a society. It gets to the legal basis of a shareholder’s personal and unlimited responsibility for the irregular dissolution of a society and the legal basis of the exception to the rule that sets the initial date of prescription in which the Public Treasury can require the redirection of the fiscal execution against the shareho
