Intellectual capital and new ventures: the entrepreneur's cognizance of company management

The purpose of this research is to analyse the intellectual capital gauges most often utilized by entrepreneurs in the management of new ventures and to relate the use of these gauges to business performance. On the basis of interview data collected from 103 entrepreneurs, we provide evidence that the use of such measuring techniques impacts positively on overall business performance. Moreover, the results indicate that those entrepreneurs utilizing some form of intellectual capital (IC) measurement have superior results. Consequently, we highlight the importance of detecting, measuring and utilizing IC for new ventures stressing the potential benefits that such analysis can have on the initial steps taken by an entrepreneur in venture formation and business development.

Positive Affectivity and Fear Trajectories in Infancy: Contributions of Mother–Child Interaction Factors

Fear and positive emotionality were considered in a growth modeling context. Mothers, primarily Caucasian (91.9%) and of middle socioeconomic status, participated in play interactions with infants at 4 months (N = 148). Infant fear and positive affectivity were evaluated at 6, 8, 10, and 12 months of age. A linear trajectory was superior in explaining growth for parent report and observation‐based indicators of positive affectivity and parent report of fearfulness; a piecewise model explained the nonlinear growth of observation‐based fear. Responsiveness in mother–infant interactions emerged as a significant predictor of the fear trajectory, with higher sensitivity predicting lower levels of observed fear. Reciprocity, tempo, emotional tone, and intensity of mother–infant interactions also made significant contributions to temperament development; however, analyses addressing these were exploratory.     

A sequential Scheffé‐type respecification procedure for controlling type I error in exploratory structural equation model modification

Regarding post hoc structural equation modeling modification, Kaplan (1990) noted in his response to Steiger (1990), “As there is currently no analogous Scheffé test, the best we can do is to free those restrictions that have the highest probability of being wrong” (p. 201). This article proposes just such an analog to the Scheffé test to be applied to the exploratory model‐modification scenario. This method is a sequential finite‐intersection multiple comparison procedure, controlling the Type I error rate to a desired alpha level across the set of all possible post hoc model modifications.     

Enhancing Early Childhood Development Through Arts Integration in Economically Disadvantaged Learning Environments

Education in the arts continues to struggle for inclusion in PreK-12 classrooms as public schools face increasing challenges from high stakes testing, Common Core politics, and endless budget cuts. Advocates point to the growing body of research linking art education to academic achievement as justification for arts’ continued inclusion in the curriculum. In its 2005 report, the National Association of State Boards of Education highlighted this research trend and called for stronger emphasis on arts in educational curricula (Meyer in Arts Educ Policy Rev 106(3):35–40, 2005). Yet despite the evidence, school districts across the nation have been slow to include more arts programming within the classroom. This study, however, examines one school district that did. In a collaborative project between a large urban school district and a local arts and science council, an arts integration program called Wolf Trap was implemented in economically disadvantaged pre-Kindergarten and first-grade classrooms at selected schools across the district. Objectives of the program were to: (a) improve school readiness skills among participants; (b) increase capacity of classroom teachers to learn and implement effective arts-based teaching strategies; and (c) increase the capacity of teaching artists to acquire and model effective arts-based teaching strategies. This study evaluates the effectiveness of the program using data from the teaching artists, classroom teachers, and the external evaluators. We discuss the program in detail and explain the methodology used in our evaluation. Finally, we present evidence that indicates the program’s success and we offer recommendations for program stakeholders.     

Guided Design: A Case Study Approach to Enhance Problem-Solving

Guided design is a systematic approach to instruction which is centered upon the learner's ability to solve open-ended problems that typify the situations he or she will experience as a professional in the field. The content is taught by self-instructional materials that have been systematically developed. The problem-solving process is taught using group projects that are designed to afford maximum utilization of the content in solving the problem presented by the case.     

Digital ITEMS Module 2: Scale Reliability in Structural Equation Modeling

In this ITEMS module, we frame the topic of scale reliability within a confirmatory factor analysis and structural equation modeling (SEM) context and address some of the limitations of Cronbach's α. This modeling approach has two major advantages: (1) it allows researchers to make explicit the relation between their items and the latent variables representing the constructs those items intend to measure, and (2) it facilitates a more principled and formal practice of scale reliability evaluation. Specifically, we begin the module by discussing key conceptual and statistical foundations of the classical test theory model and then framing it within an SEM context; we do so first with a single item and then expand this approach to a multi‐item scale. This allows us to set the stage for presenting different measurement structures that might underlie a scale and, more importantly, for assessing and comparing those structures formally within the SEM context. We then make explicit the connection between measurement model parameters and different measures of reliability, emphasizing the challenges and benefits of key measures while ultimately endorsing the flexible McDonald's ω over Cronbach's α. We then demonstrate how to estimate key measures in both a commercial software program (Mplus) and three packages within an open‐source environment (R). In closing, we make recommendations for practitioners about best practices in reliability estimation based on the ideas presented in the module.     

The development of place value concepts: Approximation before principles

Place value concepts were measured longitudinally from kindergarten (2017) to first grade (2018) in a diverse sample (n = 279; M_age = 5.76 years, SD = 0.55; 135 females; 41% Black, 38% White, 8% Asian, 12% Latino). Children completed three syntactic tasks that required an explicit understanding of base-10 symbols and three approximate tasks that could be completed without this explicit understanding. Approximate performance was significantly better in both age groups. A factor analysis confirmed that syntactic and approximate tasks tapped separate latent variables in kindergarten, but not in first grade. Path analyses indicated that only kindergarten approximate performance predicted overall first-grade place value understanding. These findings suggest that explicit understanding of base-10 principles develops from implicit, partial knowledge of multidigit numbers.     

Sense about sex: media,sex advice,education and learning

The media are widely acknowledged as important in sex and relationship education, but they are usually associated with ‘bad’ effects on young people in contrast to the ‘good’ knowledge represented by more informational and educational formats. In this paper we look at sex advice giving in newspapers, magazines and television in the UK, in sex advice books and in online spaces for sexual learning. We examine some of the limitations of the information provided, consider the challenges for sex advice in the contemporary context, and outline some of the opportunities for academics, researchers, therapists, sex educators and activists to contribute productively to sex advice giving and sexual learning more generally.
