Taking Time to Incubate: The Moderating Role of ‘What You Do’ and ‘When You Do It’ on Creative Performance

We explore how the choices available to individuals planning multi‐task work can facilitate the incubation of ideas and enhance creative performance. Using opportunistic assimilation theory, we hypothesize that two considerations can determine the effectiveness of incubation and creative performance. First, we argue that having the discretion to switch tasks when needed, as well as the timing of this discretionary switch between tasks (i.e., earlier versus later in the work process on the main task) is important. Second, the scope of the intervening task (i.e., in the same knowledge domain as the main task versus in a different domain) can lead to more effective incubation and creativity. Results of a laboratory study indicate that participants who made a discretionary switch to an intervening task later in their work process on the main task benefited significantly more in terms of creative performance than those who chose to switch earlier in their work process or chose not to switch tasks. Additionally, participants who worked on an in‐domain intervening task exhibited significantly higher creativity on the main task than those who worked on an out‐of‐domain intervening task. Furthermore, focus of attention on the main task partially mediated these results.     

When multi‐problem poor individuals' values meet practitioners' values!

Every intervention process can be thought of as a journey of partnership between people, as well as an intellectual journey of ideas and an emotional journey of relationships. This exploratory study aims at reaching a better understanding of three questions: (i) What values do individual heads of multi‐problem poor households and practitioners show regarding their relationship? (ii) How might those values inform the interaction between them, in positive and/or negative ways? (iii) What might the value system which organizes the interaction between the participants be? This study was carried out using a critical incidents technique and was based on a sample comprising two sub‐groups: 100 heads of multi‐problem poor families and 97 professionals. Findings reveal the following individual values: heads of multi‐problem poor families value instrumental support, relationships and effectiveness; while professionals' appreciate relationships, obedience to their own instructions and (in)effectiveness. These value systems seem to frame the interaction in games of responsibility avoidance that lead to the individuals' disempowerment, disguised in an aura of ‘adequate impotence’.

The association between team‐level social capital and individual‐level work engagement: Differences between subtypes of social capital and the impact of intra‐team agreement

The study explored the association between team‐level social capital and individual‐level work engagement. Questionnaire data were collected from six companies in the dairy industry. Seven hundred seventy‐two participants divided into 65 teams were included. In confirmatory factor analyses, we found a superior model fit to a four dimensional model of social capital: bonding social capital, bridging social capital and two types of linking social capital. The results showed a positive association between all subtypes of social capital at the team level and work engagement at the individual level. However, this association only remained significant for linking social capital in relation the workplace as a whole when we adjusted for psychosocial working conditions. The level of intra‐team agreement in social capital score did not moderate the association between social capital and work engagement. In conclusion, the results provide further support for previous findings suggesting a positive association between social capital and work engagement. They add to the existing knowledge by suggesting that linking social capital in relation to the workplace is the most important explanatory variable for work engagement, thus emphasizing the need to distinguish between subtypes of social capital in research and practice.     

Production planning of Pakistan Tobacco Company (PTC) using quantitative and multiple‐criteria decision analysis—A case in‐point

The main purpose of this paper is to improve the production planning of Pakistan Tobacco Company by selecting the most preferred brand and subsequently generating maximum profit from it. As the company produces a variety of products, the technique of multi criteria decision making is used to select the most preferred brand. To generate the maximum output from the preferred brand, different methods of qualitative managerial analysis are used, which include decision analysis to decide “why and where” the manufacturing should be carried out, transportation model to minimize the logistics cost while meeting the demand, and linear programming technique to maximize the profit generated in 2014–2015. The result obtained from analytical hierarchy process shows that the most preferred brand of the company with respect to price, quality, and comfort is John Player Gold Leaf. The decision analysis explains that this brand should be manufactured in the Jhelum factory of the company as it is more cost‐effective to produce and there is a high availability of resources. Transportation model minimizes the logistics cost of this brand from the 2 factories while meeting the demand at each provinces, central warehouse. Linear programming contributes in generating a profit of 32.738 billion PKR with an amount of 0.35 million PKR, which is more than that of the current profit of the company in the year. These results will allow the top management of the company to take corrective decisions well in time, gain a core competency in cost reduction, and make the supply chain process more efficient.     

The same but different: an empirical investigation of the reducibility principle

According to classical utility theory the valuation of any lottery should depend only on its outcomes and their respective probabilities, and should not be affected by the nature, complexity and structure of the chance mechanism. Previous research has documented systematic violations of this principle. For example, most subjects prefer lotteries in which the payoffs are contingent on the joint occurrence of multiple (high probability) events to simple lotteries, and lotteries in which the earlier stages offer higher probabilities than the later stages. We review the various violations of this principle and suggest a classification into two major types associated with misunderstanding of chance mechanisms and attitude towards the chance mechanism and process. In the present study 40 subjects were presented with 30 pairs of binary gambles. In any given pair the lotteries had identical outcomes and equal ‘reduced’ probabilities (and thus equal expected values). However, the chance mechanisms varied along a variety of factors such as the size of the sample space, the number of stages, temporal ordering, order of probabilities, their transparency and time constraints. Half the subjects saw lotteries involving gains and the other half considered only losses. After choosing one lottery in each pair, the subjects were asked to explain and justify their choices. The findings revealed systematic violations of the reducibility principle: subjects displayed a preference for lotteries with larger sample spaces, and for lotteries that allow quicker resolutions in the earlier stages. A clear distinction between some patterns of preferences in the gains and loss domains was revealed. In gambles involving gains subjects preferred to have the highest probability on the first stage (and the lowest probability on the last stage), but displayed the opposite preferences for losses. A content analysis of the subjects' stated reasons for their choices identified eight major categories. The most frequently invoked were hope, fun, simplicity, stress and time.

Leader personality and 360‐degree assessments of leader behavior

To investigate the relationship between personality and multi‐source feedback, we assessed 190 health care managers by applying the Understanding Personal Potential personality test, which provides comprehensive measurement of the Big Five dimensions and eight narrower personality traits. Managers' leadership behaviors were assessed by colleagues, supervisors, a random sample of each manager's subordinates as well as the managers themselves using a 360‐degree change, production, employee (CPE) instrument. Hierarchical multivariate regression analysis showed that the Big Five variables were significantly related to the Managers' leadership behavior in all CPE dimensions. Also, addition of narrow personality variables to the Big Five increased explained variance in leadership behavior. This study is the first of its kind to include the full range of viewpoints in a 360‐degree instrument, along with a large number of subordinate assessments. We found that both the strength of the relationship between personality and behavior and the configuration of different predictors varied depending on who did the rating and what leadership orientation was investigated, and this observation merits further investigation.     

A generalized distance function for preferential choices

Many cognitive theories of judgement and decision making assume that choice options are evaluated relative to other available options. The extent to which the preference for one option is influenced by other available options will often depend on how similar the options are to each other, where similarity is assumed to be a decreasing function of the distance between options. We examine how the distance between preferential options that are described on multiple attributes can be determined. Previous distance functions do not take into account that attributes differ in their subjective importance, are limited to two attributes, or neglect the preferential relationship between the options. To measure the distance between preferential options it is necessary to take the subjective preferences of the decision maker into account. Accordingly, the multi‐attribute space that defines the relationship between options can be stretched or shrunk relative to the attention or importance that a person gives to different attributes describing the options. Here, we propose a generalized distance function for preferential choices that takes subjective attribute importance into account and allows for individual differences according to such subjective preferences. Using a hands‐on example, we illustrate the application of the function and compare it to previous distance measures. We conclude with a discussion of the suitability and limitations of the proposed distance function.     

Qualitatively driven mixed‐methods approaches to counselling and psychotherapy research

Many researchers and clinicians take an ‘either, or’ position regarding factors responsible for change when conducting research. Qualitatively driven mixed methods privilege the qualitative approach and offer the opportunity to generate multi‐dimensional material, permitting a more holistic insight into experiences that can be understood from a combination of epistemological and ontological stances. A qualitatively driven mixed‐methods approach apply a ‘both, and’ position when exploring the elements that produce change or that are under investigation, which can be of particular value to counselling and psychotherapy research. There are various ways of engaging with qualitatively driven mixed methods. Some designs include both qualitative and quantitative components, where the former is the core element. The secondary component may also be qualitative, known as a multimethod design. Yet, other designs mix different qualitative approaches, through the application of different qualitative analyses to the same data (pluralistic qualitative research). This paper discusses the application and value of qualitatively driven mixed methods in counselling and psychotherapy research through the presentation of two research case studies; one which mixes both qualitative and quantitative components to investigate the experiences of pain alleviation following a CBT pain management programme; and one which applies a pluralistic approach to a counselling psychology doctorate exploring the experiences and meanings attached to self‐harming. Through illustration and discussion of the case studies’ mixed‐methods approaches, this paper demonstrates that qualitatively driven mixed methods produce a more enhanced and holistic understanding into phenomena, and therefore a more balanced perspective to counselling and psychotherapy research.     

A Multicriteria Decision‐Making Application to the Conceptual Design of Mechanical Components

Early design is crucial for the success of the final product. In the conceptual design phase, several constraints, criteria, objectives and disciplines have to be considered. To this aim, multidisciplinary optimization has proven effective for the solution of engineering design problems, even in the industrial every‐day practice, to improve and simplify the work of designers in a successful quest of the best compromise solution. In this paper, a multicriteria decision‐making (MCDM)‐based design platform for early optimal design of industrial components is proposed. In a group decision‐making context, the selection of the most suitable component among several possible layouts is performed by means of a group Fuzzy Technique for Order of Preference by Similarity to Ideal Solution approach. Hence, a multi‐objective optimization is performed on the selected component by applying a multi‐objective particle swarm optimization for finding optimal component dimensions. An industrial case study is presented for showing the efficiency of the multicriteria decision‐making‐based design platform, regarding an innovative and low‐cost solution to increase the duration of heel tips in women's shoes.
