Disentangling Gut Feeling: Assessing the Integrity of Social Entrepreneurs

This paper analyzes how social venture capitalists evaluate the integrity of social entrepreneurs. Based on an experiment with 40 social venture capitalists and 40 students, we investigate how five attributes of the entrepreneur contribute to the assessment of integrity. These attributes are the entrepreneur’s personal experience, professional background, voluntary accountability efforts, reputation and awards/fellowships granted to the entrepreneur. Results indicate that social venture capitalists focus largely on voluntary accountability efforts of the entrepreneur and the entrepreneur’s reputation when judging integrity. For an overall positive judgment of integrity, it seems to be sufficient if either voluntary accountability efforts or reputation of the entrepreneur are high. By comparing social venture capitalists with students, we show that experience leads to a simpler decision model focusing on key attributes.     

Bank management and strategic planning for the 1980s

This paper examines a number of important issues facing banking in the 1980s. The authors maintain that banking has been managing primarily by crisis, and this 'simply cannot be the operating norm'. The paper analyses a number of selected issues facing bank management in 1978 and the perceptions of bank managers about those issues vs their probable importance in 1985; furthermore, the paper examines likely operating strategies which will be required as effective responses to emerging environmental realities. Through examining the competitive realities for 1985 this paper, as have many others recently, broadens the context within which planning in banking will perhaps take place in the future.     

General scores statistics on ranks in the analysis of unbalanced designs

The authors consider the situation of incomplete rankings in which n judges independently rank k_i ∈ {2, …, t} objects. They wish to test the null hypothesis that each judge picks the ranking at random from the space of k_i! permutations of the integers 1, …, k_i. The statistic considered is a generalization of the Friedman test in which the ranks assigned by each judge are replaced by real‐valued functions a(j, k_i), 1 ≤ j ≤ k_i ≤ t of the ranks. The authors define a measure of pairwise similarity between complete rankings based on such functions, and use averages of such similarities to construct measures of the level of concordance of the judges' rankings. In the complete ranking case, the resulting statistics coincide with those defined by Hájek & ?idák (1967, p. 118), and Sen (1968). These measures of similarity are extended to the situation of incomplete rankings. A statistic is derived in this more general situation and its properties are investigated.     

Compensation and Community Corrosion: Perceived Inequalities,Social Comparisons,and Competition Following the Deepwater Horizon Oil Spill

After disasters, victim compensation programs are typically associated with individual healing and community rebuilding. But postdisaster compensation systems also have the potential to introduce confusion and competition, further fraying the social fabric of communities affected by trauma. To assess the perceived effects of disaster compensation processes on community social relations, as well as the mechanisms that underlie such effects, we turn to the case of the Deepwater Horizon oil spill, after which BP implemented one of the largest compensation systems in U.S. history. Using data from interviews of residents of four Gulf Coast communities, we examine the extent to which this claims process hindered efforts to recover from this disaster. Our data suggest that while BP money helped some residents in the Gulf during a difficult economic time, many interviewees perceived uncertainty, randomness, and unevenness in the compensation process, which led to negative social comparisons and competition among community members. Because of this animosity, we argue that BP's compensation system was a disruptive mechanism that contributed to community corrosion and introduced another source of psychological stress into already‐traumatized areas.     

Rank correlation methods for missing data

The subject of rank correlation has had a rich history. It has been used in numerous applications in tests for trend and for independence. However, little has been said about how to define rank correlation when the data are incomplete. The practice has often been to ignore missing observations and to define rank correlation for the smaller complete record. We propose a new class of measures of rank correlation which are based on a notion of distance between incomplete rankings. There is the potential for a significant increase in efficiency over the approach which ignores missing observations as demonstrated by a specific case.     

Sharing Parental Leave Among Dual-Earner Couples in Canada: Does Reserved Paternity Leave Make a Difference?

Population Research and Policy Review - In 2006, Quebec became the first Canadian province to offer non-transferable paternity leave to fathers. The availability of this five-week leave...     

Effects of an introductory letter on response rates to a teen/parent telephone health survey

The authors conducted a pilot study in preparation for a larger investigation that will rely on telephone surveys to assess select health behaviors of teens and their parents, with a focus on indoor tanning. This study used a randomized design to assess the impact of a presurvey letter on response rates to a telephone survey, as well as prevalence estimates of ever having used an indoor tanning facility. The letter did not have a significant effect on response rates or prevalence estimates in the two cities under study. Findings suggest that researchers should not assume that a letter sent in advance of a telephone survey will necessarily increase response rates enough to justify their use.     

Effects of a peer-led AIDS intervention with university students

Acquired immune deficiency syndrome (AIDS) has become a major health threat to university students. This study evaluated a peer-led AIDS intervention program with university students (1) increase knowledge of human immunodeficiency virus (HIV) transmission and infection; (2) change attitudes to reflect scientific information on AIDS-related facts; and (3) change behavioral intentions to correspond with safer sexual practices. Subjects were students (N = 142) from four undergraduate classes and were predominantly female (65%), white (82%), and sexually active (86%). A non-equivalent control group design was used, with two classes receiving the intervention and two classes receiving no information. For the intervention, peer educators presented AIDS-related information, modeled ways to use condoms safely and ways to discuss condom use with sexual partners, and led discussions on HIV infection and use with sexual partners, and led discussions on HIV infection and AIDS, relationships, sexuality, and condom use. A questionnaire was administered to assess differential changes in AIDS-related knowledge, attitudes, and behavioral intentions between the intervention and control groups. The results showed significant improvements among intervention subjects on the knowledge, attitudes, and behavioral intentions scales compared with the control group.     

ON THE SEQUENTIAL ESTIMATION OF THE PROBABILITY OF SUCCESS

Let x₁ x₂, x₃,be a sequence of independent Bernoulli trials with common success probability p . We consider the problem of estimation of p using a sequential Bayes theoretic approach when the cost per observation is c , and the loss of estimation is squared error loss. A heuristic procedure is suggested, a bound on its Bayes risk is computed, and asymptotic results are exhibited.
