Assessing the impact of the funding environment on researchers’ risk aversion: the use of citation statistics

The funding environment has a profound impact on researchers’ behavior. In particular, it influences their freedom and readiness to conduct research ventures with highly uncertain outcomes. In this conceptual paper, we propose a concise new methodology to evaluate researchers’ risk aversion based on citation statistics. The derived single-number criterion P_R is sensitive to the ratio of high impact versus average impact work, based on citation counts. We demonstrate the usefulness of P_R on a micro and meso level in the field of chemistry. P_R is a potentially valuable tool for managers in higher education, to control for the impact of their funding instruments. The conducted testing may, in addition, contribute to the literature stream dealing with the effects of peer review in the allocation of research funding. Our results support the view that peer review fosters mainstream research. However, faculties with the highest percentages of third-party funding may find ways to avoid the restrictive effects. We also find evidence that permanent positions back risky research endeavors.     

Symptoms of attention-deficit hyperactivity disorder (ADHD) and home learning environment (HLE): findings from a longitudinal study

The concept of “Home Learning Environment” (HLE) covers activities in a family providing intellectual stimulation for a child, such as reading to him or her or visiting libraries. Numerous studies have shown an association between HLE and children's cognitive development. In this longitudinal study, we focus on HLE as a predictor for children's behavioral development, namely, for later symptoms of attention-deficit hyperactivity disorder (ADHD), controlling for relevant aspects like socioeconomic status (SES), or television viewing behavior. We analyzed the development of ADHD symptoms from kindergarten to the end of grade 2 and possible associations with HLE, SES, and television exposure, using a German community sample (N?=?924). Results indicated that ADHD symptoms were negatively and significantly correlated to HLE for all five measurement points as well as to SES (except T4) and to television exposure for T1 to T4. Observing later development, only early HLE but not SES or television exposure served as a significant predictor for ADHD symptoms at school, when age, sex, and ADHD symptoms in kindergarten were controlled for. A structural equation model showed that HLE acted as a mediator between SES and later ADHD symptoms. Our results highlight the importance of the concept of home learning environment also for children's behavioral development. As a consequence, parents should be supported in offering their children a more favorable learning environment.     

Casting the die before the die is cast: the importance of the home numeracy environment for preschool children

Mathematical competencies are important not only for academic achievement at school but also for professional success later in life. Although we know a lot about the impact of “Home Literacy Environment” on the development of early linguistic competencies, research on “Home Numeracy Environment” (HNE) and the assessment of its influence on the development of mathematical abilities is in its infancy. We still lack studies analysing this relationship and simultaneously controlling for other variables concerning the individual and the environment. Thus, in this article, we focussed on the development of mathematical competencies in a sample of 609 German children from the end of kindergarten until the end of Grade 1. In particular, we were interested in the role HNE plays in regard to this development while controlling for age, sex, intelligence, rapid naming, number span, linguistic competencies, kindergarten attendance and socioeconomic status. Moreover, HNE was compared between families with or without a history of mathematical disability. HNE was not only an important predictor of mathematical abilities at the end of kindergarten, but it also influenced the further development of mathematical competencies above and beyond its initial impact. Families with a history of dyscalculia provided a more unfavourable HNE than families with no such problems. Results are shown in a structural equation model, which highlights the importance of HNE. The findings indicate that those involved in policy and intervention should focus more on the learning environments in families to improve children's achievement.

Real options theory,flexibility and the media industry

Abstract

This conceptual paper is based on two propositions: 1.) An efficient flexibility management is a critical success factor for media companies. 2.) The concept of real options theory (ROT) aims at improving a company's flexibility management. As a consequence, it is analysed how ROT can contribute to the flexibility management in media companies. In this context, two research issues are investigated. First, it is shown that real options as substantiations of flexibility are of great importance for media companies: In doing so, it is outlined that options which focus on a company's fixed costs management and options which aim at improving a company's sales situation are of high relevance for all segments in the media industry. Contrarily, options which focus on a company's variable costs are only relevant for media companies engaged in the print segment. Second, it is illustrated how ROT can contribute to the reactive and proactive management of flexibility in media companies.     

The Influence of the Congruence Between Brand and Consumer Personality on the Loyalty to Print and Online Issues of Magazine Brands

An important development in the theory of brands has been the concept of a brand personality as part of the brand image. The construct of congruence relates the personality of brands to the self-concept of consumers. It is assumed that congruence between the recipient's perception of his or her own personality and his or her perception of the brand personality leads to a higher degree of loyalty. The congruence construct has been proven to be a loyalty-promoting factor in various studies for consumer good brands. Whether the influence of congruence also exists with regard to media brands has, however, not yet been examined. As a step to close the gap, this research explores the effects of congruence on consumer loyalty in the media, taking the leading German news magazine brands— Focus, Spiegel, and Stern—which are published in print and online, as a case. The study uses a structural equation model, which is estimated by the partial least squares method, based on a questionnaire answered by 736 respondents. The model was tested for all respondents and those with print and online preference separately. As a result, the influence of congruence on loyalty could also be detected in our media case. Differences of the impact within the models for print and online give rise to the assumption that a differentiated approach to brand management in these two fields has to be taken into consideration.     

Effects of Negative Political Advertising on Individuals' Cynicism and Self-Efficacy: The Impact of Ad Type and Message Exposures

Prior research has indicated that exposure to negative political advertising can foster among individuals feelings of alienation, distrust, and apathy toward government or the political process. However, investigation regarding the amount of exposure to such advertising and the form in which it is presented remains scant. This experimental study examined the impact of ad type (character based vs. issue based) and amount of advertising exposures on individuals' cynicism and perceived self-efficacy in relation to the government. Results indicated that issue-based attack ads aired during the 2004 presidential election led to greater cynicism and lower self-efficacy than did character-based attack ads. A significant interaction revealed that the difference on the self-efficacy measure was greatest at the highest exposure level, indicating that continual exposure to ads dealing with governmental policies may nurture the perception that the political process is overly complex, which subsequently can decrease individuals' beliefs that they can make a difference.     

Uruguay's utopian broadcasting: Political and artistic freedom

It is perhaps inevitable, but none the less disturbing to discover errors, in standard reference works. The source of the error may be well hidden, but it is the responsibility of each researcher to check “accepted” findings, whenever opportunity presents itself. This is as true with respect to bibliographic citations as to research data or analysis. This “research coup” by Frank Kahn is one of several comments on Lawrence Lichty's “Who's Who on Firsts: A Search for Challengers” published in the Winter, 1965–66 issue of the Journal. Many corrections or additions were published in the Spring, 1966, issue, and readers are urged to send in other “challenges” as soon as possible. Mr. Kahn, Lecturer in radio and television at Queens College, has contributed to the Journal of Broadcasting in the past.
