Soziale Unterstützung, soziale Belastungen und Gesundheit bei leicht hilfebedürftigen Betagten

Zusammenfassung: Der Beitrag befasst sich mit der Bedeutung verschiedener sozialer Teilnetze für soziale Unterstützung und Belastung und untersucht den Einfluss von sozialer Unterstützung und Belastung auf den Gesundheitszustand von Betagten. 171 (t1, 1992) bzw. 135 (t2, 1993) leicht pflegeoder betreuungsbedürftige Betagte im Alter von mindestens 75 Jahren aus drei Zürcher Stadtkreisen wurden mit einem strukturierten Interview zweimal mündlich befragt. Die Ergebnisse zeigen, dass die familialen und ausserfamilialen Sozialbeziehungen für die befragten Frauen und Männer eine zentrale soziale Ressource für die Mobilisierung von praktischer und emotionaler Unterstützung bilden. Während sich Männer durch das familiale Sozialnetz (v.a. die Partnerschaft) am stärksten unterstützt fühlen, spielen für Frauen sowohl familiale wie ausserfamiliale Kontakte eine wichtige Rolle. Der ausgeprägten Unterstützungsfunktion sozialer Beziehungen stehen nur relativ schwache Belastungswirkungen gegenüber. Soziale Unterstützung wirkt sich hauptsächlich indirekt positiv auf die Gesundheit aus. Im Zeitverlauf zwischen t1 und t2 verändert sich das soziale Beziehungsnetz, die soziale Unterstützung sowie der Gesundheitszustand nur wenig, wohingegen soziale Belastungen eine vergleichsweise niedrigere zeitliche Konstanz aufweise

Coping with Global Debt Crises: Debt Settlements, 1820 to 1986

The settlement of the external debt of insolvent sovereign borrowers has become one of the most important issues in relations between the north and south since the outbreak of the global debt crisis in the early 1980s. For the past eight years representatives of governments and international organizations, bankers, and scientists have suggested several proposals and plans to solve the present debt crisis. The most prominent schemes in this respect are the Baker Plan of 1985, which suggested massive new credits for the most highly indebted developing countries, and the recently adopted Brady Plan, which proposes partial debt discounts and reductions in interest rates. Both of these debt settlement proposals were initiated by the United States and are supported by the other principal creditor countries. However, despite the ten years of crisis management, world leaders have not yet agreed upon a longterm solution to the current debt problems. In the history of the capitalist world economy, the current problems of coping with a global debt crisis do not represent a unique event. Rather, recent empirical studies demonstrate that sovereign borrowers have experienced many instances of debt-servicing difficulties during the past 150 years (Eichengreen and Portes 1986; White 1986; Eichengreen and Lindert 1989; Marichal 1989; Suter 1989

Beyond Optimal Linear Tax Mechanisms: An Experimental Examination of Damage-Based Ambient Taxes for Nonpoint Polluters

The regulation of nonpoint source water pollution from agriculture is a complex problem characterized by a multiplicity of polluters, informational asymmetries, complex fate and transport processes, and stochastic environmental factors. Taken together, these characteristics make regulatory policy based on individual firm emissions prohibitively costly. To circumvent this issue, economists, beginning with the seminal work of Segerson (1988), have devised economic incentive instruments that assign liabilities based on deviations between the observed ambient water quality level and a specified pollution threshold (Xepapadeas 1991; Horan, Shortle and Abler 1998, 2002; Hansen 1998, 2002). In the special case of a linear damage function, the regulator can optimally set the parameters of Segerson's (1988) incentive scheme solely with information on the damage function. When the damage function is nonlinear, a depiction that likely represents many watersheds, Segerson's incentive scheme is firm-specific, and the regulator must acquire costly firm-specific data on factors such as input use, land management practice, and soil type. Using a linear damage function setting, recent laboratory experimental economics efforts have investigated the ambient-based mechanisms proposed by Segerson, as well as some simple variants (Spraggon 2002, 2004; Poe et al. 2004; Vossler et al. 2005). A fundamental limitaion of this body of research, however, is that has utilized an "optimal design" in which the threshold pollution level for triggering the abient-based policy is set equal to the social optimum. It is therefore unclear whether subjects are optimally responding to the tax and threshold combination, or simply trying to reacting to the focal point created by the threshold. A second limitation of past experimetnal economics research is that, following Segerson, these investigations have utilized the limited case of a linear tax function. While a tax policy is relatively straightforward to apply when damages are linear, the application to real world situations may be limited. A more believable circumstance is that economic damages increase at an increasing rate as ambient pollution levels rise. This paper advances the experimental literature on ambient based pollution mechanisms in two important ways. First, by employing a range of marginal tax rates and threshold levels, we show that subjects do in fact respond optimally to the tax and cutoff combination. Second, by using the damage based tax proposed Hansen (1998) and Horan et al. (1998), we show that aggregate results when the economic damages from ambient water pollution are nonlinear are not significantly different from corresponding results under the linear tax.Environmental Economics and Policy,

Do Opposites Attract? Educational Assortative Mating and Dynamics of Wage Homogamy in Switzerland 1992-2014

This paper addresses homogamy and assortative mating in Switzerland. The empirical analysis monitors trends for education and hourly wages using the Swiss Labour Force Survey and the Swiss Household Panel. The analysis disentangles the effects of educational expansion from mating patterns and incorporates not only couples, but also singles. Results show an increasing level of assortative mating both for education and for wages. For wage homogamy, selection is more important than adaptation

Pathophysiology and diagnosis of cancer drug induced cardiomyopathy

The clinical manifestations of anti-cancer drug associated cardiac side effects are diverse and can range from acutely induced cardiac arrhythmias to Q-T interval prolongation, changes in coronary vasomotion with consecutive myocardial ischemia, myocarditis, pericarditis, severe contractile dysfunction, and potentially fatal heart failure. The pathophysiology of these adverse effects is similarly heterogeneous and the identification of potential mechanisms is frequently difficult since the majority of cancer patients is not only treated with a multitude of cancer drugs but might also be exposed to potentially cardiotoxic radiation therapy. Some of the targets inhibited by new anti-cancer drugs also appear to be important for the maintenance of cellular homeostasis of normal tissue, in particular during exposure to cytotoxic chemotherapy. If acute chemotherapy-induced myocardial damage is only moderate, the process of myocardial remodeling can lead to progressive myocardial dysfunction over years and eventually induce myocardial dysfunction and heart failure. The tools for diagnosing anti-cancer drug associated cardiotoxicity and monitoring patients during chemotherapy include invasive and noninvasive techniques as well as laboratory investigations and are mostly only validated for anthracycline-induced cardiotoxicity and more recently for trastuzumab-associated cardiac dysfunctio
