Trust your instincts:The relationship between intuitive decision making and happiness

Epstein (1994; 2003) proposed that there are two cognitive information processing systems that operate in parallel: the intuitive thinking style and the rational thinking style. Decisional fit occurs when the preferred thinking style is applied to making a decision and research has shown that this fit increases the value of the outcome of a decision. Additionally, decisional fit leads to less regret, even when post hoc evaluations show the decision to be incorrect. It has not yet been determined whether decisional fit correlates with greater happiness and hence, the purpose of the current study was to investigate the difference between styles of thinking, styles of decision making and the impact of decisional fit on happiness scores. Individual differences in thinking and decision style were measured using an online interactive questionnaire (N = 100), and an ANOVA, hierarchical multiple regression, and a series of t-tests, were used to investigate the relationship between thinking style, decision style, decisional fit, and happiness, thereby addressing a gap in the existing literature. The major findings from the current study show that intuitive thinking has a strong positive correlation with happiness; that intuitive thinkers are more likely to utilize intuitive decisional style, than rational thinkers; and that when both rational and intuitive thinkers experienced decisional fit, higher ratings of happiness were reported. Explanations and recommendations for future studies are outlined in the discussion

The relationship between ILL/document supply and journal subscriptions

Purpose: The purpose of this article is to provide insights into the relationship between ILL/ document supply and journal subscriptions and to assess recent trends in the ILL service. Design/methodology/Approach: This survey is based on data from the ILL service conducted over the five year period 2005-2009 through the Italian NILDE (Network for Inter-Library Document Exchange) network. Findings: This article bears out important previous findings that ILL is not used as a surrogate for journal subscriptions. This is supported by the analysis of a broad number of titles and over a wide time-range. On the contrary, analysis of data transactions, particularly of the most requested journals, can bring about positive effects on new title acquisitions and negotiations with publishers. This paper also shows, at least for Italy, an overall growth and vitality of ILL, in spite of the widespread availability of e-journals acquired through consortia purchasing. Originality/Value: An insight into the relationship between ILL and journal subscriptions in Italy, a country where few studies have been carried out, and none at all for such a large number of libraries and transactions

Contacts with, and attitudes toward, the mentally ill in the New Zealand police : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University

Irregular pagination: pg 56 missingDeinstitutionalisation and changes to the Mental health Act (1992) relating to committal and treatment for those with a mental illness has resulted in increased numbers of people with a mental illness living in the community. Internationally these changes in the care of mentally ill people have resulted in increased contacts between the police and the mentally ill. The present study investigated the amount, and nature of, contacts between the New Zealand police and the mentally ill and the attitudes of the police toward mentally ill persons using Cohen and Struenings Opinions about Mental Health (OMI) scale. Self-administered questionnaires were distributed to all police stations within region three of the New Zealand police districts and a total of 261 sworn police participated. The results show that New Zealand police, like their international colleagues, experience regular contacts with the mentally ill that are time consuming, stressful and largely non-criminal in nature. While the police expressed a dislike to attending call outs involving the mentally ill, their attitudes as measured by the OMI were overall positive and accepting of mentally ill people. The participants expressed a desire for additional training and education to better prepare themselves to deal with the mentally ill

On rate optimality for ill-posed inverse problems in econometrics

In this paper, we clarify the relations between the existing sets of regularity conditions for convergence rates of nonparametric indirect regression (NPIR) and nonparametric instrumental variables (NPIV) regression models. We establish minimax risk lower bounds in mean integrated squared error loss for the NPIR and the NPIV models under two basic regularity conditions that allow for both mildly ill-posed and severely ill-posed cases. We show that both a simple projection estimator for the NPIR model, and a sieve minimum distance estimator for the NPIV model, can achieve the minimax risk lower bounds, and are rate-optimal uniformly over a large class of structure functions, allowing for mildly ill-posed and severely ill-posed cases.Comment: 27 page

Solving ill-posed bilevel programs

This paper deals with ill-posed bilevel programs, i.e., problems admitting multiple lower-level solutions for some upper-level parameters. Many publications have been devoted to the standard optimistic case of this problem, where the difficulty is essentially moved from the objective function to the feasible set. This new problem is simpler but there is no guaranty to obtain local optimal solutions for the original optimistic problem by this process. Considering the intrinsic non-convexity of bilevel programs, computing local optimal solutions is the best one can hope to get in most cases. To achieve this goal, we start by establishing an equivalence between the original optimistic problem an a certain set-valued optimization problem. Next, we develop optimality conditions for the latter problem and show that they generalize all the results currently known in the literature on optimistic bilevel optimization. Our approach is then extended to multiobjective bilevel optimization, and completely new results are derived for problems with vector-valued upper- and lower-level objective functions. Numerical implementations of the results of this paper are provided on some examples, in order to demonstrate how the original optimistic problem can be solved in practice, by means of a special set-valued optimization problem
