A Comprehensive Model of Entrepreneur Role Stress Antecedents and Consequences

Purpose  The aim of this study was to systematize findings in role stress research into original and conceptually important abstract higher-order constructs and to develop and test a comprehensive structural equation model that examined such expanded conceptualizations of antecedents and consequences to entrepreneur role stress. Design/Methodology/Approach  Model tests were performed on data from a sample of 282 Swedish entrepreneurs (a usable rate of 22.5%) engaged in their first-year of venture activities. We used structural equation modeling, mediation tests and tests for common method bias to test the appropriateness of the model. Findings  We found that role stress can be explained by expansions of lower-ranked, less abstract constructs embedded in a multiple-indicator model of venture technology, venture environment, and entrepreneur personality. The analysis confirmed that role stress is an important mediator and that it has pronounced relationships to expanded conceptualizations of role-related rewards and exhaustion. Implications  This study advance role stress theory and existing knowledge about entrepreneurs and entrepreneurship when it introduces role stress and suggests it mediates the effects from personality traits, organizational and environmental characteristics, on higher-order conceptualizations of rewards and exhaustion. Originality/Value  With contributions from several distinct disciplines over a half decade, prior research has not paid much attention to show how role stress research can benefit from more abstract conceptualizations and empirical evaluation. By synthesizing and developing expanded higher-level conceptualizations that link diversities, we show that expanded conceptualizations effectively enable to introduce role stress to entrepreneurs and entrepreneurship.     

The Mediating Effects of Psychological Contracts on the Relationship Between Human Resource Systems and Role Behaviors: A Multilevel Analysis

Purpose  The purpose of this study was to examine the mediating effect of the psychological contracts on the relationship between human resource (HR) systems and role behavior. Design/Methodology/Approach  Multilevel analyses were conducted on data gathered from 146 knowledge workers and 28 immediate managers in 25 Taiwanese high-tech firms. Findings  Relational psychological contracts mediated the relationship between commitment-based HR systems and in-role behaviors, as well as organizational citizenship behaviors. Transactional psychological contracts did not significantly mediate these relationships. In addition, the results also indicated that commitment-based HR systems related positively to relational psychological contracts and negatively to transactional psychological contracts. Practical Implications  Commitment-based HR systems could elicit a wide range of knowledge workers’ behaviors that are beneficial to the goals of the firms. Furthermore, our findings also provide insight into, how HR systems potentially elicit employees’ role behaviors. Organizations could elicit employees’ in-role behaviors by providing financial and other non-financial, but tangible, inducements and facilitate employees’ extra-role behaviors by providing positive experiences, such as respect, commitment, and support. Originality/Value  The study is one of the primary studies to empirically examine the mediating effect of psychological contracts on HR systems and employee behaviors.

The “Obama Effect”: How a salient role model reduces race-based performance differences

Barack Obama, the first Black-American president, has been widely heralded as a role model for Black-Americans because he inspires hope. The current study was conducted to assess whether, beyond simply inspiring hope, this “Obama Effect” has a concrete positive influence on Black-Americans’ academic performance. Over a three-month period we administered a verbal exam to four separate groups of Black- and White-American participants at four predetermined times. When Obama’s stereotype-defying accomplishments garnered national attention - just after his convention speech, and election to the presidency - they had a profound beneficial effect on Black-Americans’ exam performance, such that the negative effects of stereotype threat were dramatically reduced. This effect occurred even when concerns about racial stereotypes continued to exist. The fact that we found performance effects with a random sample of American participants, far removed from any direct contact with Obama, attests to the powerful impact of ingroup role models.     

汉语词类歧义解决(Ⅱ)

采用眼动记录阅读范式,考察汉语词类歧义解决过程。阅读材料为含有单字词类歧义词的句子,歧义词前面的语境不提供明确的偏向性信息,后语境提供解歧信息。结果发现,当后语境支持次要用法时,歧义词及后面第一个解歧区的总阅读时间加长,歧义词后第二个解歧区的回扫次数增多,而当后语境支持主要用法时没有出现类似的现象,表明相对频率能够即时影响词类歧义解决过程,结果支持基于制约的模型。文章对汉语词类歧义解决过程、不同实验技术及其引起的差异进行了讨论。     

The discounting of ambiguous information in economic decision making

In three experimental studies we investigated how decision makers respond to ambiguous information about costs and benefits. In Experiment 1, we studied the effect of ambiguity about prior costs. Experiments 2 and 3 focused on the effect of ambiguity about future outcomes. The collective results of the three studies suggest that decision makers discount ambiguous information. The findings are related to insights on the disjunction effect, the sunk cost effect, transaction decoupling, and ambiguity aversion. Copyright © 2003 John Wiley & Sons, Ltd.     

Good-Enough Representations in Language Comprehension

People comprehend utterances rapidly and without conscious effort. Traditional theories assume that sentence processing is algorithmic and that meaning is derived compositionally. The language processor is believed to generate representations of the linguistic input that are complete, detailed, and accurate. However, recent findings challenge these assumptions. Investigations of the misinterpretation of both garden-path and passive sentences have yielded support for the idea that the meaning people obtain for a sentence is often not a reflection of its true content. Moreover, incorrect interpretations may persist even after syntactic reanalysis has taken place. Our good-enough approach to language comprehension holds that language processing is sometimes only partial and that semantic representations are often incomplete. Future work will elucidate the conditions under which sentence processing is simply good enough.     

Validité de construit d’une épreuve de jeu de rôle dans le cadre d’un centre d’évaluation chez des officiers de marine.

The present study was designed to obtain validity estimates for a role-play test. Participants were 125 french Navy officers who were rated by a pool of professional assessors and psychologists. All the assessors received reccurring training sessions, focusing on the behavioral checklist, on rating errors, and on share frame of reference. The assessment procedure included role play exercise, cognitive ability scale (g factor) and personality scale (big five factors). First, exploratory factor analyses were conducted on the data gathered, and four factors were identified (authoritarianism, oral communication, consideration with others and frankness). In a nomological perspective, we also analysed the links between the exercises dimensions, personality inventorie and intelligence scale. The findings suggest that role play dimension, personality and intelligence seem to measure different thinks.     

Putting lexical constraints in context into the visual-world paradigm

Prior eye-tracking studies of spoken sentence comprehension have found that the presence of two potential referents, e.g., two frogs, can guide listeners toward a Modifier interpretation of Put the frog on the napkin… despite strong lexical biases associated with Put that support a Goal interpretation of the temporary ambiguity (Tanenhaus, M. K., Spivey-Knowlton, M. J., Eberhard, K. M. & Sedivy, J. C. (1995). Integration of visual and linguistic information in spoken language comprehension. Science, 268, 1632–1634; Trueswell, J. C., Sekerina, I., Hill, N. M. & Logrip, M. L. (1999). The kindergarten-path effect: Studying on-line sentence processing in young children. Cognition, 73, 89–134). This pattern is not expected under constraint-based parsing theories: cue conflict between the lexical evidence (which supports the Goal analysis) and the visuo-contextual evidence (which supports the Modifier analysis) should result in uncertainty about the intended analysis and partial consideration of the Goal analysis. We reexamined these put studies (Experiment 1) by introducing a response time-constraint and a spatial contrast between competing referents (a frog on a napkin vs. a frog in a bowl). If listeners immediately interpret on the… as the start of a restrictive modifier, then their eye movements should rapidly converge on the intended referent (the frog on something). However, listeners showed this pattern only when the phrase was unambiguously a Modifier (Put the frog that’s on the…). Syntactically ambiguous trials resulted in transient consideration of the Competitor animal (the frog in something). A reading study was also run on the same individuals (Experiment 2) and performance was compared between the two experiments. Those individuals who relied heavily on lexical biases to resolve a complement ambiguity in reading (The man heard/realized the story had been…) showed increased sensitivity to both lexical and contextual constraints in the put-task; i.e., increased consideration of the Goal analysis in 1-Referent Scenes, but also adeptness at using spatial constraints of prepositions (in vs. on) to restrict referential alternatives in 2-Referent Scenes. These findings cross-validate visual world and reading methods and support multiple-constraint theories of sentence processing in which individuals differ in their sensitivity to lexical contingencies.     

Too Much Reference: Semantics for Multiply Signifying Terms

The logic of singular terms that refer to nothing, such as ‘Santa Claus,’ has been studied extensively under the heading of free logic. The present essay examines expressions whose reference is defective in a different way: they signify more than one entity. The bulk of the effort aims to develop an acceptable formal semantics based upon an intuitive idea introduced informally by Hartry Field and discussed by Joseph Camp; the basic strategy is to use supervaluations. This idea, as it stands, encounters difficulties, but with suitable refinements it can be salvaged. Two other options for a formal semantics of multiply signifying terms are also presented, and I discuss the relative merits of the three semantics briefly. Finally, possible modifications to the standard logical regimentation of the notion of existence are considered.
