Different induction therapies for kidney transplantation with living donor.

INTRODUCTION Indications for induction therapy is not consensual in living donors. OBJECTIVE The objective of this study was compare no induction with thymoglobulin and basiliximab induction in the incidence of acute rejection in kidney transplantation with living donor. METHODS We select all cases of renal transplantation with living donor performed in Hospital das Clínicas de Botucatu da UNESP during the period of January 2010 to December 2013. The group was divided by the type of medication used for induction. RESULTS A total of 90 patients were evaluated. There were no differences in baseline characteristics of age and underlying disease. The rate of biopsy-proven acute rejection was higher in the group without induction (42.9%) compared to basiliximab group (20%) and Thymoglobulin (16.7%), p = 0.04. The rejection by compatibility shows that the identical had the lower rejection rate (10%). The haploidentical group without induction had the highest rejection rates (53.3%). In all distinct group the rejection rates were similar with basiliximab or Thymoglobulin, p = NS. The use of induction therapy was associated independently with a lower risk of rejection (OR = 0.32 CI: 0.11 to 0.93, p = 0.036). There were no differences in renal function at 6 months and patient survival and graft in the three groups. DISCUSSION The haploidentical patients without induction were those with higher rates of acute rejection. The group of patients induced with Thymoglobulin had a higher immunological risk, however showed low rates of rejection. CONCLUSION The use of induction therapy resulted in lower rates of rejection in transplantation with living donor.
Insider Trading around Dividend Announcements: Theory and Evidence

The informational role of strategic insider trading around corporate dividend announcements is studied based on the efficient equilibrium in a signaling model with endogenous insider trading. Insider trading immediately prior to the announcement of dividend initiations has significant explanatory power. For firms with insider selling prior to the dividend initiation announcement, the excess returns are negative and significantly lower than for the remaining firms (with no insider trading or just insider buying) as implied by the authors' model. Another implication is that dividend increases may elicit a positive or negative stock price response depending on the firm's investment opportunities. Copyright 1991 by American Finance Association.
Intergenerational transfers of time and money in European families: common patterns — different regimes?

The `generational contract' is the most important and also the most contentious dimension of contemporary welfare systems. Much of the debate on how to reform it is still truncated, however, by focusing on its public dimension only, especially on pensions and health-care provisions. For a full account, the transfer of resources between adult generations in the family needs to be included as well. So far, research on family transfers has almost exclusively been limited to single-country studies. In this article, we present a comparative study of financial transfers and social support in ten Western European countries based on the Survey of Health, Ageing and Retirement in Europe (SHARE) conducted in 2004. Our results confirm, at the European level, the existence of a common transfer pattern. There is a net downward flow from the older to the younger generations, both by inter vivos financial transfers and by social support. Transfers from the elderly parents to their children are much more frequent and also usually much more intense than those in the opposite direction. The positive balance decreases with age but even those over the age of 70 clearly remain net givers. Our results also demonstrate that country-specific transfer patterns follow the typology of welfare regimes. Transfers from parents to children are less frequent but more intense in the Southern European countries than in the Nordic ones, with the Continental European countries being somewhere in between the two. This welfare regime effect still holds after controlling for the most relevant characteristics of the parents.
Interval risk aversion

The conventional measures of absolute and relative risk aversion are appropriate for measuring preferences locally, but because they rely on differential calculus, they cannot accurately capture attitudes towards high-stakes risks involving potentially large changes in wealth. Eisenhauer (2006) has recently proposed an alternative approach which avoids the use of calculus. The present article extends that work in two ways. First, the Pratt–Arrow coefficient of absolute risk aversion is generalized into a measure of interval risk aversion, suitable for analysing preferences over risks of any magnitude, and a corresponding interval measure of relative risk aversion is constructed from preference and risk parameters, without explicit reference to initial wealth or income. Second, the new measures are applied to survey data from the Bank of Italy, to illustrate their empirical applicability to large-scale risk.
Laparoscopic Fimbrioplasty and Neosalpingostomy in Female Infertility: A Review of 402 Cases at the Gynecological Endoscopic Surgery and Human Reproductive Teaching Hospital in Yaoundé-Cameroon

Background: More than 70 million couples suffer from infertility worldwide. The aim of this study was to evaluate the fertility outcomes after laparoscopic fimbrioplasty and neosalpingostomy in female infertility. Methods: Laparoscopic distal tuboplasty was carried out for 402 cases at the Gynecological Endoscopic Surgery and Human Reproductive Teaching Hospital in Yaoundé-Cameroon in Central Africa from December 2002 to December 2007. Laparoscopic fimbrioplasty and neosalpingostomy were done using bipolar electrocoagulation and conventional endoscopic instruments. Log-rank test was used to compare cumulative rate curves of intrauterine pregnancy with respect to the tubal stages. P<0.05 was considered statistically significant. Results: The mean age of the patients was 31.6±5.45 years. Secondary infertility was the most frequent type of infertility (70.14%). The laparoscopic tubal surgery done consisted of fimbrioplasty in 185(46%) cases and neosalpingostomy in 217 (54%) cases. Of 260 women followed up after tuboplasty, there were overall 74 (28.48%) pregnancies; 68(26.1%) intrauterine pregnancies and 6(2.3%) ectopic pregnancies. Pregnancy rates were significantly associated to the tubal stage (63% in stage 1, 15% in stage 3 and 00% in stage 4; p<0.001) and the adnexal adhesion scores (73.91% in the absence of adnexal adhesions and 8.8% in the case of a severe adnexal adhesion score). Of the 68 intrauterine pregnancies, there were 60(88%) live births and 8(12%) spontaneous abortions. Conclusion: It is believed that laparoscopic fimbrioplasty and neosalpingostomy should be the preferred choice when faced with tubal distal occlusion in a context of female infertility. This implies that training in endoscopic surgery should be regarded as an important issue in developing countries.
Terrorism in a Bargaining Framework

A LTHOUGH hostage seizures are a small percentage of terrorist incidents, they represent some of the most spectacular and influential events.2 The takeover of the American embassy in Tehran on November 14, 1979, the seizure of eleven dPEC oil ministers on December 21, 1975, and the capture and killing of nine Israeli athletes on September 5, 1972, are incidents not easily forgotten. From 1968 through 1982, of the approximately 8,000 reported terrorist events, 540 (7 percent) were transna-
Demodex aurati sp.nov. and D. criceti, ectoparasites of the Golden Hamster (Mesocricetus auratus)

A new species, Demodex aurati, is described from the Golden Hamster, Mesocricetus auratus. It differs in both morphological detail and ecological niche from D. criceti present on the same host. When pieces of heavily parasitized skin were ‘subplanted’ for 100 days no change in morphological features of either D. aurati or D. criceti occurred. D. aurati is a low grade pathogen, apparently only harvesting the cells of the follicular epithelium. The life cycle of D. aurati is described. The presence on one host species of two different species of this genus, which has affinities with demodicids of evolutionally remotely related hosts, poses an interesting problem in species specificity and ectoparasite evolution. I wish to thank Dr Miriam Shaw, Miss Shirley DiBenedetto and Miss Helen Krause for their excellent technical help, and Dr Lawrence Bartlett and Dr Harold Rauch for perusal of the manuscript and suggestions on project procedure.

Developing a 'consultation quality index' (CQI) for use in general practice.

BACKGROUND The core values of general practice include holism and patient-centredness. None of the measures of quality of care in general practice presently capture the expression of these values at routine consultations. OBJECTIVES The aim of the present study was to construct a 'consultation quality index' (CQI) which reflects the core values of general practice, using as proxies 'consultation length' and how well patients 'know the doctor' as process measures and 'patient enablement' as an outcome measure. METHODS The CQI was constructed from data collected from 23 799 adult English-speaking patients consulting 221 doctors in four demographically contrasting areas of the UK during 2 weeks of March/April 1998. A total of 171 doctors who entered 50 qualifying consultations were allocated scores for the three component variables, and a total CQI was calculated. RESULTS CQI scores were in the range 4-18. Validity was examined by looking at high and low scorers in greater detail and by searching for correlates with case mix, patient age and gender, and the deprivation scores of the practices concerned. Particular attention was paid to how registrars and doctors new to their practices scored. The scores of different doctors in the same practice were also noted. The results had strong face validity and were independent of case mix and deprivation. Reliability was gauged by examining similar work from a previous study which had collected information on consultation length and enablement over three time periods. High CQI scores were associated with smaller overall practice list sizes. CONCLUSIONS We have outlined possible uses for the CQI as part of the packages assessing quality of care by doctors and practices. The measure may also have a part to play in recognizing poorly performing doctors. We suggest how CQI scores could contribute to an incentive scheme to reward good consulting practice. Further work is in hand to compare doctors' CQI scores with scores based on performance indicators constructed from routine NHS data on prescribing and preventive medicine.
Earnings Distribution and the Valuation of Shares: Some Recent Evidence

Questions have been raised in recent years concerning the interpretation of previous studies purporting to show that distributed earnings have had a consistently greater impact on equity prices than have retained earnings. Miller and Modigliani have convincingly argued that if capital markets are perfect and rational behavior of market participants is assumed, the price-earnings ratio of the shares of a firm with a given investment policy should be invariant to alternative earnings-payout ratios. They also point out, however, that with the present tax subsidy on capital gains and the existence of substantial brokerage fees and flotation costs, dividend policy might be expected to have an effect on share prices, even though the amount and direction of this effect is an empirical matter and not determinable a priori.
Introduction: the problem-solving capacity of multi-level governance

In the post-war decades, advanced capitalist economies have developed in symbiosis with democratic political systems with a high capacity for effective regulation and welfare-state compensations. As economic integration deepens globally and even more so within the European Community, national capacities to regulate and to tax mobile capital and firms are reduced, whereas governance at European or international levels is constrained by conflicts of interest among the governments involved. Nevertheless, as the contributions to this volume show, the effectiveness of problem-solving at the national as well as at the European and international levels varies considerably from one field to another. In this introduction, I attempt to identify the factors that could explain the varying intensity and direction of competitive pressures on national regulatory systems, as well as the greater or lesser political feasibility of European or international regulation.
A Generalized Stochastic Dominance Program for the IBM PC

Abstract A microcomputer program to perform Generalized Stochastic Dominance (GSD), Quasi-Second Degree Dominance (SSD), and Quasi-First Degree Stochastic Dominance (FSD) is described. The program is designed to run on IBM-compatible personal computers with a Hercules or CGA graphics adapter. It is menu-driven and has options for GSD, quasi-FSD, quasi-SSD, graphics, and calculations of premiums associated with use of dominant distributions.
Leadership and Pandering: A Theory of Executive Policymaking

We develop an informational theory that analyzes conditions under which a reelection-seeking executive will act in the public interest. The theory considers factors such as executive competence, challenger quality, and the likelihood that voters will learn the consequences of policy decisions before an upcoming election. We . nd that an executive who has information suggesting that a popular policy is contrary to voters’ interests may or may not pander to voters by choosing it; under certain conditions, the executive can actually increase his probability of reelection by choosing an unpopular policy that is in the public interest. However, we also show that an executive will sometimes face electoral incentives to enact a policy that is both unpopular and contrary to voters’ interests. We illustrate our model with examples involving President Abraham Lincoln, California Governor Earl Warren, and President Gerald Ford. ¤For helpful comments we thank Steve Ansolabehere, David Austen-Smith, Dan Carpenter, Cary Covington, Patricia Conley, Daniel Diermeier, Tim Fedderson, Fred Greenstein, Keith Krehbiel, Dan Kryder, Jim Snyder, Craig Volden, and seminar participants at Berkeley, Dartmouth, Harvard, MIT, Northwestern, NYU Law School, Princeton, Stanford, and SUNY Stony Brook. yAssistant Professor of Political Science, MIT. zAssistant Professor of Political Science, Northwestern University. xCorresponding author.

Trends in Federal Funds Rate Volatility

The behavior of the fed funds rate-a key monetary policy target and a benchmark for short-term interest rates-is closely watched by many market participants. After a decade marked by periodic bouts of high volatility in the funds rate, volatility has declined sharply since 2001. An analysis of the major factors influencing the rate's behavior shows that some of the forces behind the current fall in volatility first emerged in response to the earlier increases.
INFORMATIONAL ASYMMETRIES, FINANCIAL STRUCTURE, AND FINANCIAL INTERMEDIATION

NUMEROUS MARKETS ARE characterized by informational differences between buyers and sellers. In financial markets, informational asymmetries are particularly pronounced. Borrowers typically know their collateral, industriousness, and moral rectitude better than do lenders; entrepreneurs possess "inside" information about their own projects for which they seek financing. Lenders would benefit from knowing the true characteristics of borrowers. But moral hazard hampers the direct transfer of information between market participants. Borrowers cannot be expected to be entirely straightforward about their characteristics, nor entrepreneurs about their projects, since there may be substantial rewards for exaggerating positive qualities. And verification of true characteristics by outside parties may be costly or impossible. Without information transfer, markets may perform poorly. Consider the financing of projects whose quality is highly variable. While entrepreneurs know the quality of their own projects, lenders cannot distinguish among them. Market value, therefore, must reflect average project quality. If the market were to place an average value greater than average cost on projects, the potential supply of low quality projects may be very large, since entrepreneurs could foist these upon an uninformed market (retaining little or no equity) and make a sure profit. But this argues that the average quality is likely to be low, with the consequence that even projects which are known (by the entrepreneur) to merit financing cannot be undertaken because of the high cost of capital resulting from low average project quality. Thus, where substantial information asymmetries exist and where the supply of poor projects is large relative to the supply of good projects, venture capital markets may fail to exist. For projects of good quality to be financed, information transfer must occur. We have argued that moral hazard prevents direct information transfer. Nonetheless, information on project quality may be transferred if the actions of entrepreneurs ("which speak louder than words") can be observed. One such action, observable because of disclosure rules, is the willingness of the person(s) with inside information to invest in the project or firm. This willingness to invest may serve as a signal to the lending market of the true quality of the project; lenders will place a value
The Association between Bankruptcy Outcome and Price Reactions to Bankruptcy Filings

This study investigates the association between bankruptcy outcome and the capital market's reaction to bankruptcy filings. Our sample consists of 77 firms that filed bankruptcy petitions between 1980 and 1996. We investigate whether, at the time of bankruptcy filing, the market differentiates between firms that are subsequently liquidated and firms that are subsequently reorganized. Our results indicate that liquidated firms have significantly larger negative price reactions at bankruptcy filing than reorganized firms. This result holds after controlling for a going-concern audit report in the period prior to bankruptcy filing, a technical or debt service default in the period prior to bankruptcy filing, firm size, prior Wall Street Journal announcement of a possible bankruptcy filing, firm financial condition, and other predisclosure information. Our findings suggest that the market has a high degree of insight into the subsequent bankruptcy resolution.
An empirical equilibrium job search model with search on the job and heterogeneous workers and firms

In this article we present and estimate a synthesis of previous equilibrium search models, allowing for continuous distributions of workers' opportunity costs of employment as well as firms' productivities. The model allows for on-the-job search, and we assume that job offer arrival rates for workers are independent of their labor-market state. We derive the theoretical implications of these assumptions, we provide simulations, and we develop a semiparametric estimation procedure that we apply to a dataset of individual labor-market histories.
Realizing Product-Market Advantage in High-Technology International New Ventures: The Mediating Role of Ambidextrous Innovation

Abstract This study examines the pivotal role of ambidextrous innovation in the strategy–performance thesis of the export ventures of high-technology international new venture (INV) firms. To date, the literature on INVs has failed to consider ambidextrous innovation in the strategy interplay in approaching new markets overseas. Building on the resource-based view of the firm, the authors empirically examine the relationships among competitive strategy, innovation ambidexterity, positional advantage, and export venture performance. In the context of Mexican high-technology INVs, the authors find that innovation ambidexterity codetermines both marketing differentiation and cost leadership advantages, and together these link to export venture performance gains. The authors reveal that marketing differentiation and cost leadership strategies positively influence differentiation and cost advantages, respectively. They observe hybrid strategy to influence marketing differentiation advantage inversely. Moreover.
The road to quality enhancement in tourism

The aim of this paper is to identify reasons for current quality problems in tourism and possible ways of enhancing tourism quality. To attain this goal, recent initiatives directed at quality improvement in tourism are first presented. Primary and secondary data have been utilised to achieve this. Systems theory is utilised in order to recognise the reasons for current quality problems. Evaluation of quality management processes is based on Dale and Plunkett’s model of levels in the evolution of quality management. The SERVQUAL model and the benchmarking technique are critically evaluated. The existence and inability of closing the tourism quality perception gap and the tourism quality control gap have been identified as chief causes of private sector tourism quality systems ineffectiveness. Three conditions of tourism quality enhancement have been formulated and a new tourism quality system that complies with these requirements has been proposed. A need for establishing a Total Quality Tourism Consortium as a formal body is emphasised.
Market Making by Price-Setting Firms

A model of market making by firms with heterogeneous consumers, suppliers and price-setting intermediaries is examined. Consumers and suppliers engage in time-consuming search for the best price and discount future returns. There exists a unique symmetric equilibrium pricing strategy. In equilibrium, there are non-degenerate distributions of ask and bid prices that straddle the Walrasian price. As the discount rate goes to zero, the ranges of the bid and ask prices, and the total output approach the Walrasian equilibrium values. As the discount rate becomes large, the ask and bid prices approach the monopoly pricing policies. An increase in the discount rate leads to an increase in the equilibrium number of active firms, profit per firm, the mean spread between ask and bid prices, and the variance of ask and bid prices, while lowering the number of active consumers and suppliers. The model is extended to examine the steady-state market equilibrium with continual entry and exit of consumers and suppliers.
