Individual research performance: A proposal for comparing apples to oranges

The evaluation of performance at the individual level is of fundamental importance in informing management decisions. The literature provides various indicators and types of measures, however a problem that is still unresolved and little addressed is how to compare the performance of researchers working in different fields (apples to oranges). In this work we propose a solution, testing various scaling factors for the distributions of research productivity in 174 scientific fields. The analysis is based on the observation of scientific production by all Italian university researchers active in the hard sciences over the period 2004–2008, as indexed by the Web of Science. The most effective scaling factor is the average of the productivity distribution of researchers with productivity above zero.     

Does Maternal Employment Following Childbirth Support or Inhibit Low‐Income Children’s Long‐Term Development?

This study assessed whether previous findings linking early maternal employment to lower cognitive and behavioral skills among middle‐class and White children generalized to other groups. Using a representative sample of urban, low‐income, predominantly African American and Hispanic families (n = 444), ordinary least squares regression and propensity score matching models assessed links between maternal employment in the 2 years after childbearing and children’s functioning at age 7. Children whose mothers were employed early, particularly in their first 8 months, showed enhanced socioemotional functioning compared to peers whose mothers remained nonemployed. Protective associations emerged for both part‐time and full‐time employment, and were driven by African American children, with neutral effects for Hispanics. Informal home‐based child care also heightened positive links.     

Education for Older People in Italy

This article provides information on trends in formal and informal adult education in Italy, with a particular focus on the older learners (over 65). Main providers, programs, objectives/motivations, and financial and legal framework are described. In general, over-65-year-old people were found to be underrepresented in participation. They were also concentrated in activities of informal education (through, for example, Third Age Universities) instead of formal courses that are oriented mainly towards the development of skills/competencies for the labor market. In order to improve the situation of older people in the future, the question of financing is one of the main challenges to be addressed by policymakers.     

Coordinating innovation projects with high tech suppliers through contracts

This paper investigates the supply chain (SC) management and innovation strategies with the purpose to identify: 1) which commercial contracts are suitable to coordinate SC innovation projects; 2) which motivations push SC members to adopt contracts to pursue innovation projects; and 3) how contractual clauses differ in different stages of the innovation process. A comparative case study among five High Tech (HT) companies in the Netherlands uncovers the motivations for adopting certain contracts over others. The findings illustrate that contracts discussed in the literature (sales-rebate, buy back, revenue sharing, etc.) successfully work for commercial agreements but not at all for coordinating joint innovation projects. Motivations for adopting these contracts do not limit to general company characteristics but also stretch from historical reasons to future strategies. The findings help HT companies to setting up the basis of a contract to coordinate joint innovation projects within SCs.     

An Intellectual Capital perspective for Business Model Innovation in technology-intensive industries: empirical evidences from Italian spin-offs

Innovation and competition take place increasingly between Business Models (BM), and not just among products, processes, and technologies. Therefore, Business Model Innovation (BMI) becomes the key process to unleash value creation for both established and new companies, and, among these latter, particularly for technological spin-offs. For their constituent characteristics, it emerges that BMI in technological spin-offs appears to be related to the effective management of the Intellectual Capital (IC). Despite this, current research has paid little attention to decline BMI through the lenses of IC. This study aims to provide a contribution in this direction by investigating how technological spin-offs innovate their BM by leveraging their IC dimensions. A review of relevant literature on BMI has been carried out. Then, a case study methodology has been adopted to analyze seven technological spin-offs. The analysis highlighted three main trajectories of BMI, defined in terms of the BMI scope and the main exploited IC dimension. The discussion of findings from a research and practical perspective contributes to the debate on BMI, by providing a new interpretative key based on the relevance of the IC dimensions.     

The FarmBuiLD model (farm building landscape design): First definition of parametric tools

The paper presents a set of synthetic architectural parameters dealing with the morphological aspects of rural buildings. The definition of these parameters represents a fundamental step of the FarmBuiLD research model (farm building landscape design), proposed by the authors as a tool for the analysis of the architectural characteristics of both historical and contemporary rural buildings, as well as the meta-design of new construction and transformation of contemporary rural buildings. The FarmBuiLD's module of physiognomical characterization of rural buildings allows to define the analytical-design parameters through the following phases: a critical analysis of the international scientific literature, a preliminary identification of the essential physiognomical characteristics of rural buildings, and an in-depth study of validation and calibration focusing on specific study cases. This work presents the preliminary definition of the parameters and a discussion about their experimental application through illustrative examples. Given their numeric value and strictly instrumental, thematic and complementary nature, the proposed parameters do not have any geometric, formal or stylistic characterization, and thus can be considered as capable of leaving an appropriate level of freedom within the design of solutions aimed at meeting both contemporary and future functional and aesthetic needs.     

Does chess instruction improve mathematical problem-solving ability? Two experimental studies with an active control group

It has been proposed that playing chess enables children to improve their ability in mathematics. These claims have been recently evaluated in a meta-analysis (Sala & Gobet, 2016, Educational Research Review, 18, 46–57), which indicated a significant effect in favor of the groups playing chess. However, the meta-analysis also showed that most of the reviewed studies used a poor experimental design (in particular, they lacked an active control group). We ran two experiments that used a three-group design including both an active and a passive control group, with a focus on mathematical ability. In the first experiment (N = 233), a group of third and fourth graders was taught chess for 25 hours and tested on mathematical problem-solving tasks. Participants also filled in a questionnaire assessing their meta-cognitive ability for mathematics problems. The group playing chess was compared to an active control group (playing checkers) and a passive control group. The three groups showed no statistically significant difference in mathematical problem-solving or metacognitive abilities in the posttest. The second experiment (N = 52) broadly used the same design, but the Oriental game of Go replaced checkers in the active control group. While the chess-treated group and the passive control group slightly outperformed the active control group with mathematical problem solving, the differences were not statistically significant. No differences were found with respect to metacognitive ability. These results suggest that the effects (if any) of chess instruction, when rigorously tested, are modest and that such interventions should not replace the traditional curriculum in mathematics.     

Oddity of visual patterns conceptualized by pigeons

Pigeons were trained to learn an instrumental oddity-from-sample discrimination involving visual forms. One group, the “few examples” group, dealt with 5 patterns in 40 different combinations. Another group, the “many examples” group, dealt with 20 patterns in 160 different combinations. After both groups had reached asymptotic performance and had learned to operate under partial reinforcement conditions, they were tested for transfer under extinction conditions with two different groups of 5 novel patterns, each in 40 combinations. All animals showed significant above chance transfer to both of these novel stimulus sets. Transfer performance with test stimuli of similar geometric design to training stimuli was better than performance with stimuli of markedly different design. The transfer performance of the “many examples” group was marginally better than that of the “few examples” group, even though the latter’s performance on the training stimuli was better throughout. It is concluded that pigeons can learn to employ an oddity concept and that this may be promoted by the use of many training exemplars. Furthermore, it is inferred that pigeons may normally use a mixture of strategies to solve oddity and identity problems.
