On ranking opportunity distributions

Our results show the intimate relationship between a large group of apparently different rankings of opportunity distributions. First, we provide a set of core basic axioms that are intuitively plausible under any concern for equality or efficiency aspects. Second, we introduce two very opposed views of the problem by incorporating different perspectives of the notion of advantage (better opportunity set) and we provide some axioms that might be defended under such extreme positions. For any of these two different perspectives, we characterize the families of rankings which satisfy the core axioms and the group of axioms corresponding to that view. These characterizations will prove insightful to better understand most of the criteria already introduced in the literature, which are part of the families we study.     

On ranking linear budget sets in terms of freedom of choice

This paper examines how freedom of choice as reflected in an agents opportunity sets can be measured in economic environments where opportunity sets are linear budget sets in the non-negative orthant of the n-dimensional real space. Three axioms, Symmetry, Monotonicity and Invariance of Scaling Effects, are proposed for this purpose and the measure based on volumes of budget sets is characterized. I am grateful to Prasanta K. Pattanaik for his encouragement and fruitful discussions over many years on this and related subjects. The first draft of this paper was written while I was visiting the Institute of Economic Research at Hitotsubashi University in Japan. I would like to thank its hospitality. Helpful comments of a referee are gratefully acknowledged.     

Path independent choice and the ranking of opportunity sets

The indirect utility principle provides an instrumentalist basis for ranking opportunity sets, given an underlying preference ranking on alternatives. Opportunity set A is weakly preferred to B if A includes at least one preference-maximising element from $A\cup B$ . We introduce the Plott consistency principle as a natural extension of this logic to decision-makers who choose amongst alternatives according to a path independent choice function. Such choice functions need not be rationalisable by a preference order. Plott consistency requires that A is an acceptable choice from $\left\{ A, B\right\} $ if A includes at least one element from the set of acceptable choices from $A\cup B$ . We explore necessary and sufficient conditions (imposed on a choice function defined on collections of opportunity sets) for Plott consistency.     

The evaluation ranking scale: a new methodology for assessing satisfaction

Most patient satisfaction scales produce high, undifferentiated levels of reported satisfaction that fail to detect program areas that consumers do not like. Methodological problems apparently contribute to these results. An alternative procedure, the Evaluation Ranking Scale (ERS), was formulated and tested. A 2 X 3 design was employed with 246 public health center patients randomly assigned to one of two measurement techniques (ERS vs. a global measure) and one of three informational sets. A secondary group of subjects was a convenience sample of 26 staff members, which allowed comparisons of staff evaluations of the health center to patients' evaluations of the health center. Compared to the global measure, the ERS provided more specific information about particular program components, was more discriminating, and resulted in mean satisfaction scores that were significantly lower. This new approach may be a more effective technique for assessing the psychosocial effectiveness of human service programs.     

Micro foundations of multi-prize lottery contests: a perspective of noisy performance ranking

This article proposes a multi-prize noisy-ranking contest model. Contestants are ranked in descending order based on their perceived performance, which is subject to random perturbation, and they are rewarded based on their ranks. Under plausible conditions, we establish that our noisy performance ranking model is stochastically equivalent to the family of multi-prize lottery contests built upon ratio-form contest success functions. We further establish the equivalence of our model to a contest model that ranks contestants by their best performance out of multiple independent attempts. These results therefore shed light on the micro-foundations of the popularly adopted lottery contest models. The “best-shot ranking rule” reveals a common thread that connects a broad class of seemingly disparate competitive activities (such as rent-seeking contests, patent races, research tournaments), and unifies them through a common performance evaluation mechanism.

On the influence of extreme parties in electoral competition with policy-motivated candidates

We study and compare equilibrium platforms in models of unidimensional electoral competition with two and four policy motivated parties. We first analyze the plurality game, where the party getting the most votes is elected and implements its proposed platform. Restrictions on the set of credible announcements are needed to get existence of equilibria. Comparing equilibria with two and four parties, we obtain that moderate parties react to the introduction of extreme parties by proposing the same or more extreme equilibrium platforms. We then study the proportional system, where the policy implemented is a weighted sum of the proposals, with the voting shares as weights. Here, the existence of extreme parties leads moderate ones to choose more centrist platforms. We finally test the robustness of our results with respect to, first, the enlargement of the strategy space to entry decisions and, second, to asymmetric distributions of voters' blisspoints.

The evaluation ranking scale: clarification of methodological and procedural issues

Compared with CSQ-8, a typical questionnaire approach to assessing global patient satisfaction, the Evaluation Ranking Scale (ERS) had equally good patient acceptability, yielded more normally distributed satisfaction scores, and results allowed comparative information about patients' evaluation of specific service dimensions. The study also addressed key questions that have emerged about the ERS procedure. Patients apparently do not distinguish conceptually between "importance" of dimensions and "satisfaction" with dimensions in the first phase (ranking) of the ERS. Results did confirm that the ERS sequence of ranking and then rating the dimensions is essential to achieving optimal utility of results. The ranking task seems to have an organizing effect on patients' approach to the rating task. This effect does not work to dictate results in the rating phase but rather seems to familiarize patients with the dimensions to be rated thereby yielding greater potential discriminative capacity for the ERS. Finally, results indicate that the ERS can be administered in a flexible fashion that yields additional information about the absolute importance of the six dimensions without loss of desired operating characteristics for the measure.     

Product option framing under the influence of a promotion versus prevention focus

Investigations into the option framing effect involve the use of a subtractive versus an additive option-framing method to gauge their impact on consumer behaviors. This research examines how option framing could affect choice decisions as a function of a consumer’s goal orientation. Study 1 offers convergent support for the proposition that regulatory focus moderates the option framing effect and the mediating role of action/inaction on the relationship between regulatory focus and the option framing effect. In particular, a reverse finding shows that promotion-focused consumers provided with a +OF options list tend to choose more options than those who are given a −OF option list. To explain the reverse effect, Study 2 examines and demonstrates regulatory fit as a possible moderator. The results of Study 2 also confirm our inference and echo the same results of Study 1. Finally, based on the regulatory fit theory, Study 3 examines if cognitive constraints associate with a consumer’s regulatory orientation may also account for the interaction between regulatory focus and option framing. The results of Study 3 also support the proposition.

On the memory of a chronic illness

The elderly are particularly susceptible to disease, yet the biological mechanisms that bring about this susceptibility remain unclear. Using atherosclerosis as a model chronic illness, we review how recent studies of bone marrow-derived vascular repair systems in mice and humans provide new insights into the causes and potential cures for age-related illness. Organisms are born with a finite capacity for stem cell-mediated repair after chronic exposure to tissue injury. Once that capacity is exhausted, a cycle of pathological inflammation ensues and leads to overt disease manifestations. Augmentation of stem cell-mediated repair systems may provide a novel means of treating or preventing many age-related illnesses.     

How the size of a coalition affects its chances to influence an election

Since voting rules are prototypes for many aggregation procedures, they also illuminate problems faced by economics and decision sciences. In this paper we are trying to answer the question: How large should a coalition be to have a chance to influence an election? We answer this question for all scoring rules and multistage elimination rules, under the Impartial Anonymous Culture assumption. We show that, when the number of participating agents n tends to infinity, the ratio of voting situations that can be influenced by a coalition of k voters to all voting situations is no greater than $D_{m} \frac{k}{n}Since voting rules are prototypes for many aggregation procedures, they also illuminate problems faced by economics and decision sciences.

Recent results on individual manipulability in three alternative elections show that this estimate is exact for k=1 and m=3.

The influence of the economic crisis on quality of care for older people: system readiness for innovation in Europe

The aim of this study is to examine the influence of the recent economic crisis on the quality of long-term care for older people in Belgium and the Netherlands. A mixed-method approach was applied, primarily focused on conducting semi-structured qualitative interviews with health professionals working in a management role in organizations providing long-term care for older people. The results show that Dutch organizations seem to be prepared for the influences of the economic crisis on the quality of its care provision primarily in terms of a sound system readiness. At the same time, Belgian organizations seem to be prepared for the influences of the economic crisis on the quality of its care provision primarily in terms of a favorable sociopolitical context. Comparing two countries allows for reciprocal lesson-drawing. The conclusion drawn in this study is that a sustainable long-term care system requires above all stability and structure.     

The influence of a grandfather's disease process and death on the formation of personal identity in a granddaughter

This case study investigated the influence of a grandfather with Parkinson's disease and his death on the development of personal identity in his granddaughter. The case was complicated by the granddaughter's diagnosis at age 20 with a potentially terminal illness 3 months after his death. The granddaughter experienced symptoms similar to those of her grandfather. Analysis of a retrospective interview with the granddaughter revealed four themes: shared interests, coping skills and adaptation, enlightenment, and influence. These themes were examined within the context of Erik H. Erikson's theory of identity development as a conceptual framework for understanding the influence of the grandfather–granddaughter relationship.     

Disentangling social media influence in crises: Testing a four-factor model of social media influence with large data

Social media empower publics by providing a platform for their voices during crises. Digital-enabled platforms allow individuals to become influentials by sharing their insights and expertise with others. Confronted with the fast-paced and complex dynamics of crises, we lack a systematic conceptualization and a valid measure of social media influence in the crisis context. By integrating diverse perspectives on influence, we propose a new framework that theorizes different dimensions of social media influence based on publics’ communicative behaviors during crises. This integrated framework offers a refined conceptualization and measurement of social media influence in crises by incorporating the network perspective. We tested the framework with large-scale Twitter data from four crises. Results from multigroup CFA on Twitter influencers suggest that social media influence is composed of four factors: output, reactive outtake, proactive outtake, and network positioning. Each factor is associated with a distinct set of users’ behavioral indicators (e.g., retweet). Implications for crisis communication and public relations are discussed.     

Military-civilian differences in a driving under the influence (DUI) program sample

ABSTRACT

It is unknown how military-connected participants in DUI programs differ from civilians on sociodemographic, health, and alcohol severity factors. This study analyzed data from 19,639 DUI program participants from 2009 to 2014. Compared to civilians, active duty participants were younger, more likely male and married/partnered or separated, less likely disabled, more likely to be Black, less likely to report anxiety or involvement in domestic violence, more likely to report prior alcohol treatment and having a first-time conviction, and less likely to score in the problematic drinking category. Veterans showed patterns similar to those of active duty with some notable exceptions. Results may be helpful in tailoring culturally competent DUI program content, particularly among social workers who often serve this population.     

Recreation as a component of the community youth development system

In an era of fragmented school systems and budget cuts, many educators and youth leaders seeking to solve the problems that youth face are turning to out-of-school-time programs. In many communities, these programs are seen as essential in the development of youth into fully functioning adults. One such area of the out-of-school-time sector is the provision of recreation services. Recreational services have a vital role in connecting youth to their communities, as well as enabling youth and adult allies to improve challenging conditions. This chapter outlines the historical role that recreation has played in community youth development programs and shows how community youth development has evolved. It then looks at how organizations in three communities--the Youthline Outreach Mentorship program in Minneapolis, a 4-H initiative in Parker City, Texas, and the Hockey Is for Everyone program--have successfully applied the theoretical knowledge. Best practices from these programs illustrate that the role of recreation in community youth development is changing. No longer are recreation programs about providing just "fun and games." Recreation organizations are now placing more value on the development of the community as a whole, in addition to the individual well-being of young people.
