Statistical and Methodological Myths and Urban Legends in Strategic Management Research: The Case of Moderation Analysis

This paper examines whether methodological precedence in applying moderation analysis to strategic management research relies on myths and urban legends, and if doing so affected empirical conclusions, implications for theory development, and practical recommendations. An in‐depth analysis of 69 studies published in the Strategic Management Journal between 2000 and 2014 using moderation analysis finds that strategic management scholars typically rely on statistical myths and urban legends when applying moderation analysis including: (1) interpreting main effects separately from their significant interaction with other variables; (2) failing to report reliability values of interaction terms; and (3) relying on hierarchical approaches that can lead to interpretation errors. Further examples illustrate how these practices could lead researchers to draw incomplete and possibly inaccurate conclusions. Overall, problematic precedents have become the gold standards for testing and interpreting moderation models. Best practice recommendations for redirecting future research to more solid methodological grounding are provided.
Marketing and the Creative Problem-Solving Process

In the aggregate, marketing may be conceptualized as the process of offering creative solutions to consumer problems. As such, educational emphasis should be given to increasing students’ knowledge of the creative problem-solving (CPS) process. Unfortunately, past research has given little attention to the CPS process itself. The purpose of this article is to better familiarize marketing educators with the CPS process and its connection to marketing practice. In addition, an instructional approach is offered that employs the use of assorted CPS techniques in conjunction with different stages of the CPS process.
Search trails using user feedback to improve video search

In this paper we present an innovative approach for aiding users in the difficult task of video search. We use community based feedback mined from the interactions of previous users of our video search system to aid users in their search tasks. This feedback is the basis for providing recommendations to users of our video retrieval system. The ultimate goal of this system is to improve the quality of the results that users find, and in doing so, help users to explore a large and difficult information space and help them consider search options that they may not have considered otherwise. In particular we wish to make the difficult task of search for video much easier for users. The results of a user evaluation indicate that we achieved our goals, the performance of the users in retrieving relevant videos improved, and users were able to explore the collection to a greater extent.
Interpersonal Dynamics in Personality and Personality Disorders

Clinical and basic personality psychologists interact less than they should, given their similar interests. In clinical personality psychology, available evidence supports a transition from the current categorical system to a hierarchical trait scheme for diagnosing the stable features of personality disorder. However, trait models do not capture the dynamic aspects of personality disorders as they have been described in the clinical literature, and thus miss a clinically critical feature of personality pathology. In contrast, basic personality psychologists have coalesced around a consensual structure of individual differences and become increasingly interested in the dynamic processes that underlie and contextualize traits. But trait psychology models are not sufficiently specific to characterize dynamic personality processes. In this paper, I filter clinical descriptions of personality disorders through the lens of interpersonal theory to specify a recursive within–situation interpersonal pattern of motives, affects, behaviours, and perceptions that could contribute to the stable between–situation patterns of maladaptive behaviour of historical interest to both basic and clinical personality psychologists. I suggest that this interpersonal model adds specificity to recent proposals regarding processes in the basic personality literature and has significant potential to advance research on personality dynamics. © 2018 European Association of Personality Psychology
Asset Prices Under Short-Sale Constraints

In this paper, we study how short-sale constraints affect asset price and market efficiency. We consider a fully rational expectations equilibrium model, in which investors trade to share risk and to speculate on private information in the presence of short-sale constraints. Short-sale constraints limit both types of trades, and thus reduce the allocational and informational efficiency of the market. Limiting short sales driven by risk-sharing simply shifts the demand for the asset upwards and consequently its price. However, limiting short sales driven by private information increases the uncertainty about the asset as perceived by less informed investors, which reduces their demand for the asset. When this information effect dominates, short-sale constraints actually cause asset prices to decrease and price volatility to increase. Moreover, we show that short-sale constraints can give rise to discrete price drops accompanied by a sharp rise in volatility when prices fail to be informative and the uncertainty perceived by uninformed investors surges.

Diversity as Interactive Practice : Theoretical and Methodological Contributions from a Discursive Psychological Approach to Issue Framing Summary

The special issue on Cultural Diversity collects a selection of papers presented at the multidisciplinary and multinational Marie Curie project on " Cultural diversity in Europe: A series of Conferences " (EURODIV). EURODIV focuses on cultural diversity in Europe and aims to understand the ways of dealing with diversity and its dynamics in the globalisation era. Its primary objective is to provide top-level training opportunities to researchers in the first years of their research career. Summary We conceptualize organizational diversity situations as contexts where people with different backgrounds are interdependent in performing their tasks or achieving their goals. We use the concept of frames and we focus on dealing with differences in issue framing in order to capture diversity at the level where it takes the form of divergent views on the issues at hand. For researching the interactive process of issue framing and reframing, the qualitative research approach of discourse and conversation analysis proves very useful. This methodological approach allows capturing what happens with divergent frames throughout the process of interaction, in which issues are negotiated through formulating and reformulating them. Theoretically, a discursive psychological approach to frame diversity moves away from an essentialist approach to diversity in terms of individual or group properties, towards a view where diversity is continuously enacted and dealt with in discursive practices between people from different backgrounds who work on specific tasks or issues. 1 Diversity Diversity in its many facets has important consequences for organizing. Our approach to the study of diversity is in line with those who argue that diversity research should go beyond the number of different identity group affiliations on the payroll. Thomas & Ely (1996: 80) understand diversity as " the varied perspectives and approaches to work that members of different identity groups bring ". Different groups bring specific knowledge about how to go about the work: " how to design processes, reach goals, frame tasks, create effective teams, communicate ideas, and lead " (Thomas & Ely, 1996: 80). They argue that organizational practices that are able to incorporate employees' diverse perspectives into the main work of the organization can improve effectiveness by rethinking tasks, redefining markets and products, reformulating strategies or redesigning business practices. In inter-organizational or multi-actor settings, diversity in views, interests and competences provides the basis for innovation and constructive integration of differences (Vansina & Taillieu, 1997). Diversity is at the same time a big …
Patterns in the English language: phonological networks, percolation and assembly models

In this paper we provide a quantitative framework for the study of phonological networks (PNs) for the English language by carrying out principled comparisons to null models, either based on site percolation, randomization techniques, or network growth models. In contrast to previous work, we mainly focus on null models that reproduce lower order characteristics of the empirical data. We find that artificial networks matching connectivity properties of the English PN are exceedingly rare: this leads to the hypothesis that the word repertoire might have been assembled over time by preferentially introducing new words which are small modifications of old words. Our null models are able to explain the ‘power-law-like’ part of the degree distributions and generally retrieve qualitative features of the PN such as high clustering, high assortativity coefficient and small-world characteristics. However, the detailed comparison to expectations from null models also points out significant differences, suggesting the presence of additional constraints in word assembly. Key constraints we identify are the avoidance of large degrees, the avoidance of triadic closure and the avoidance of large non-percolating clusters.
Combination of Diane-35 and Metformin to Treat Early Endometrial Carcinoma in PCOS Women with Insulin Resistance

Background: Young women with polycystic ovary syndrome (PCOS) have a high risk of developing endometrial carcinoma. There is a need for the development of new medical therapies that can reduce the need for surgical intervention so as to preserve the fertility of these patients. The aim of the study was to describe and discuss cases of PCOS and insulin resistance (IR) women with early endometrial carcinoma while being co-treated with Diane-35 and metformin. Methods: Five PCOS-IR women who were scheduled for diagnosis and therapy for early endometrial carcinoma were recruited. The hospital records and endometrial pathology reports were reviewed. All patients were co-treated with Diane-35 and metformin for 6 months to reverse the endometrial carcinoma and preserve their fertility. Before, during, and after treatment, endometrial biopsies and blood samples were obtained and oral glucose tolerance tests were performed. Endometrial pathology was evaluated. Body weight (BW), body mass index (BMI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), sex hormone-binding globulin (SHBG), free androgen index (FAI), insulin area under curve (IAUC), and homeostasis model assessment of insulin resistance (HOMA-IR) were determined. Results: Clinical stage 1a, low grade endometrial carcinoma was confirmed before treatment. After 6 months of co-treatment, all patients showed normal epithelia. No evidence of atypical hyperplasia or endometrial carcinoma was found. Co-treatment resulted in significant decreases in BW, BMI, TT, FAI, IAUC, and HOMA-IR in parallel with a significant increase in SHBG. There were no differences in the FSH and LH levels after co-treatment. Conclusions: Combined treatment with Diane-35 and metformin has the potential to revert the endometrial carcinoma into normal endometrial cells in PCOS-IR women. The cellular and molecular mechanisms behind this effect merit further investigation.
Support Vector Regression Based Indoor Location in IEEE 802.11 Environments

The wide spread of the 802.11-based wireless technology brings about a good opportunity for the indoor positioning system. In this paper, we present a new 802.11-based indoor positioning method using support vector regression (SVR), which consists of offline training stage and online location stage. The model that describes the relations between the position and the received signal strength (RSS) of the mobile device is established at the offline training stage by SVR, and at the online location stage the exact position is determined by this model. Due to the complex indoor environment, RSS is vulnerable and changeable. To address this issue, data filtering rules obtained through statistical analysis are applied at offline training stage to improve the quality of training samples and thus improve the quality of prediction model. At the online location stage, -times continuous measurement is utilized to obtain the high quality RSS input, which guarantees the consistency with the training samples and improves the position accuracy of mobile devices. Performance evaluation shows that the proposed method has a higher positioning accuracy compared with the probability and neutral network method, and the demand for the storage capacity and computing power is also low at the same time.
What Does It Take to Become a Good Engineer?: Identifying Cross-National Engineering Student Profiles According to Perceived Importance of Skills

Engineers of the future are expected to possess a range of competencies in addition to math and science skills. This paper turns toengineering students to explore what they think it takes to become a good engineer. Profiles are identified by means of a large-scalesurvey-based investigation of the perceptions of first year engineering students in the US and in Denmark with respect to theimportance of math/science skills and interpersonal and professional skills for successful engineering. Four groups of first yearengineering students are defined according to combinations of high and low importance assessments of each of the two skill typesin both countries. This leads to analytically derived groups emphasizing math/science skills, interpersonal and professional skills,both skill types, and none of the skills. Differences and similarities between these groups are explored in terms of relative groupsizes and gender composition, levels of confidence, and motivation to study engineering. The findings show that the fourengineering student groups have distinct profiles with different characteristics in terms of motivation and confidence and whichmay each require different educational approaches to become broad thinking engineers. Apart from the exploratory investigation ofgroup differences within each country, the paper also examines whether the four group profiles are nationally confined or ifcommon tendencies shared by engineering students in both countries exist. The paper contributes to the literature on engineeringeducation and serves to inform engineering educators and institutions worldwide with new insights into the expectations andperceptions of actual students who are at the very beginning of their pathway to an engineering education.
Learning to Predict Independent of Span

We consider how to learn multi-step predictions efficiently. Conventional algorithms wait until observing actual outcomes before performing the computations to update their predictions. If predictions are made at a high rate or span over a large amount of time, substantial computation can be required to store all relevant observations and to update all predictions when the outcome is finally observed. We show that the exact same predictions can be learned in a much more computationally congenial way, with uniform per-step computation that does not depend on the span of the predictions. We apply this idea to various settings of increasing generality, repeatedly adding desired properties and each time deriving an equivalent span-independent algorithm for the conventional algorithm that satisfies these desiderata. Interestingly, along the way several known algorithmic constructs emerge spontaneously from our derivations, including dutch eligibility traces, temporal difference errors, and averaging. This allows us to link these constructs one-to-one to the corresponding desiderata, unambiguously connecting the `how' to the `why'. Each step, we make sure that the derived algorithm subsumes the previous algorithms, thereby retaining their properties. Ultimately we arrive at a single general temporal-difference algorithm that is applicable to the full setting of reinforcement learning.
Taking an Interest in Taking the Lead: The Influence of Vocational Interests, Leadership Experience and Success on the Motivation to Lead

Motivation plays a crucial role in leadership, particularly when facing difficult situations and decisions. This long-term study investigates whether vocational interests predict an individual s motivation to lead (MtL). Moreover, it examines whether the link between vocational interests and MtL is mediated by the extent and success of prior leadership experiences. To this end, 471 participants (291 male, 180 female, Mage 5 22.65, SDage 5 7.95) provided information on their vocational interests. Two years later, participants rated their MtL and provided information on both the extent of their prior leadership experiences and the respective success gained from these. Results show that enterprising and conventional interests positively affect MtL two years later. Additionally, enterprising and social interests also indirectly influence a person s motivation to lead through the extent and success of prior leadership experiences: people with higher enterprising and social interests report more prior experience in leading. This experience is linked to more self-perceived leadership success, which consequently enhances these persons motivation to take on leading roles. These findings enrich theory on the antecedents and malleability of MtL. From a practitioner s view, the findings equip recruiters with information on how to search for motivated leaders and how to maintain their motivation.
Protective cellular immunity: cytotoxic T-lymphocyte responses against dominant and recessive epitopes of influenza virus nucleoprotein induced by DNA immunization

DNA immunization offers a novel means to induce cellular immunity in a population with a heterogeneous genetic background. An immunorecessive cytotoxic T-lymphocyte (CTL) epitope in influenza virus nucleoprotein (NP), residues 218 to 226, was identified when mice were immunized with a plasmid DNA encoding a full-length mutant NP in which the anchor residues for the immunodominant NP147-155 epitope were altered. Mice immunized with wild-type or mutant NP DNA were protected from lethal cross-strain virus challenge, and the protection could be adoptively transferred by immune splenocytes, indicating the role of cell-mediated immunity in the protection. DNA immunization is capable of eliciting protective cellular immunity against both immunodominant and immunorecessive CTL epitopes in the hierarchy seen with virus infection.
A New Interpretation for the Second Peak of T Coronae Borealis Outbursts: A Tilting Disk around a Very Massive White Dwarf

A new interpretation for the second peak of T Coronae Borealis outbursts is proposed based on a thermonuclear runaway (TNR) model. The system consists of a very massive white dwarf (WD) with a tilting accretion disk and a lobe-filling red giant. The first peak of the visual light curve of T CrB outbursts is well reproduced by the TNR model on a WD close to the Chandrasekhar mass (MWD≳1.35 M), while the second peak is reproduced by the combination of the irradiated M giant and the irradiated tilting disk. The derived fitting parameters are the WD mass MWD~1.35 M, the M giant companion mass MRG~0.7 M (0.6-1.0 M☉ is acceptable), the inclination angle of the orbit i~70°, and the tilting angle of the disk iprec~35°. These parameters are consistent with the recently derived binary parameters of T CrB.
Third-party responses to injustice: a review on the preference for compensation

ABSTRACT People are often confronted with injustice that is done to others. In such cases, observers (i.e. third-parties) of injustice can restore justice by punishing the perpetrator, as shown by a vast amount of research. However, this focus on punishment has led to the neglect of another behavioural option: compensation of the victim. The current review focuses on this latter behavioural option. More specifically, it is argued that third-parties are more compensation-oriented than previous literature appears to demonstrate. To support this argument, previous research is discussed and the factors that might explain observers’ preference for compensation are outlined. To conclude, suggestions for future research are presented.
Diet as a Risk Factor for Pneumococcal Carriage and Otitis Media: A Cross-Sectional Study among Children in Day Care Centers

Background Pharyngeal bacteria are exposed to different sugar conditions depending on the diet of the child. We hypothesized that dietary factors such as daily intake of carbohydrates could be associated with pneumococcal carriage and the occurrence of otitis media in children. Methods Our study design was a cross-sectional study among 1006 children attending child day care centers. Parents filled in a food frequency questionnaire. Oropharyngeal swabs were collected from each child. The primary outcome was the occurrence of pneumococcal carriage and the secondary outcome the number of acute otitis media episodes during life. Principal component analysis was used to group dietary intake into nine factors. The models were adjusted for age, gender of the child and educational level of the mother. Results The dietary factor which included high consumption of sweet pastries and jam was associated with an increased risk of pneumococcal carriage (OR 1.17, 95% CI 1.01 to 1.36, P-value 0.04). The factor including frequent consumption of fruit and berries was associated with a decreased risk of acute otitis (regression coefficient −0.51, 95% CI −0.98 to −0.03, P = 0.04). A high intake of consumption of sweets and snacks (OR 1.36, 95% CI 1.03 to 1.80, P = 0.03) was associated with an increased risk of caries. Conclusions Diet was associated with a risk of pneumococcal carriage and the occurrence of otitis media. Diet may thus be a modifiable risk factor for the occurrence of acute otitis media.
