Human capital and innovation: mixing apples and oranges on the board of high-tech firms

PurposeThe purpose of this paper is to provide insights into the implications of board human capital heterogeneity for company innovation by focusing on the educational and the functional background of directors. Moreover, it examines the moderating effect of the CEO expertise-overlap within the innovation domain on the relationship between board human capital heterogeneity and firm innovation.Design/methodology/approachThe hypotheses are tested through a set of ordinary least squares regressions on a unique dataset of 149 Italian high-tech companies observed between 2012 and 2015.FindingsFindings show that the educational and the functional background heterogeneity of directors increase both the innovation input and output. However, results highlight that these relationships are negatively moderated by the CEO expertise-overlap within the innovation domain.Practical implicationsThe paper emphasizes the importance of appointing directors with different and specific educational and functional backgrounds to foster the company innovation.Originality/valueThe paper fills a gap in the literature as it has devoted limited attention to the performance implications of board human capital heterogeneity in the high-tech industry where knowledge and skills are the primary sources of value. Moreover, the paper integrates the research on the CEO-board interface by shedding light on how the CEO expertise within the innovation domain affects the contribution of heterogeneous boards to company innovation.
The effect of acquaintanceship on the validity of personality impressions: A longitudinal study.

Previous studies have used cross-sectional designs to demonstrate the beneficial effect of acquaintanceship on the validity of personality impressions. To counter critiques of those studies, a longitudinal design was used. Participants were randomly assigned to 16 groups of 5-7 members who met once a week for 7 weeks. None of the participants in any group were previously acquainted. Before the first meeting, they completed a battery of self-report measures, including the NEO Five Factor Inventory and the revised Interpersonal Adjective Scales
Laboratory investigation of the effect of ABS polymer on moisture susceptibility of asphalt mixtures

ABSTRACT This paper investigates the effects of Acrylonitrile Butadiene Styrene (ABS) polymer as an asphalt binder modifier on reducing the moisture susceptibility of hot asphalt mixtures. In order to recognise the efficiency of ABS polymer, repeated load tests in dry and wet conditions along with the thermodynamic parameters calculated through measuring the surface free energy (SFE) components of asphalt binders and aggregates were used. The results showed that ABS polymer caused an increase in the cohesion free energy and a reduction in the released energy of the system during stripping, indicating the reduced tendency of the system toward stripping. The results of repeated load tests supported the results obtained from the SFE method, demonstrating an improvement in moisture susceptibility of modified mixtures, especially the samples constructed by acidic aggregates. In addition, moisture sensitivity index was calculated using the thermodynamic parameters and asphalt mixtures modulus from cyclic loading tests. The results were similar to those of wet-to-dry modulus ratio and showed that ABS significantly reduced the stripping percentage of modified mixtures.
The Dinamic of Psychological Well-Being and Gratitude in Adolescence

The research aims to investigate the adolescents’ psychological well-being and gratitude. The research type is a quantitative study with a survey method. The research subjects are adolescents aged 17-21 years old comprising 13 males and 41 females. The psychological wellbeing and gratitude are measured with a scale. The instrument test items are evaluated from the correlation of total items with the product moment formula. Psychological well-being variable has 26 valid and 10 invalid statement items with the reliability value of 0.877. Meanwhile, the gratitude variable has 19 valid and 1 invalid statement items with the reliability of 0.892. The research data are analyzed using a percentage descriptive technique. Based on data analysis, it can be concluded that the adolescents’ psychological well-being is classified into the high category, while the gratitude is classified into the very high category. Due to the psychological well-being aspects, the highest percentage belongs to Purpose in Life (understanding the purpose of life). Meanwhile, the highest percentage in gratitude aspects belongs to Thank God (expressing gratitude to God). Keyword—psychological well-being, gratitude,
The Feminization of Agriculture

Male outmigration from rural, primary agricultural areas and the globalization of agri-food systems have both been linked to a significant increase in women’s work and responsibilities in agriculture, a phenomenon referred to as the ‘feminization of agriculture’. While the term has been broadly used to bring attention to the increasing number of women, relative to men, in agricultural employment, little attention has been paid to what the ‘feminization of agriculture’ means for women’s empowerment and their roles in agriculture more generally. Similarly, there is no clear understanding of how this will impact the agricultural sector and what the consequences for food and water security are. This chapter reviews the global evidence surrounding the “feminization of agriculture” and provides a critical discussion of the implications for women’s empowerment and for food and water security.
Tourism, terrorism, perceived risk and media

The purpose of this paper is to identify Portuguese residents’ apprehensions about perceived risks, including the terrorism risk, while travelling abroad. It was implemented a quantitative research methodology and there were collected samples. The factor analysis, specifically the principal component analysis with varimax rotation, was used to assess the underlying structure of Portuguese tourist’s risk perception. We found four dimensions, namely, “risk in international trips”, “interest in terrorism news”, “perceived importance of safety” and “generalized insecurity”. The perceived risk dimensions were collapsed into one and using logistic regression analysis, the risk dimension was regressed against a set of independent variables to determine which factors influence the Portuguese tourist’s perceived risks. The results show that monthly net income, perception of terrorism in Africa, risk aversion, level of education, travel companion, number of international trips and thinking that travelling is risky nowadays are significant to the model.The purpose of this paper is to identify Portuguese residents’ apprehensions about perceived risks, including the terrorism risk, while travelling abroad.

Work-Life Balance and Glass Ceiling of Women Employees – A Literature Review

Literature Review is an outline of all the information accessible on a particular subject till date. When you choose a research topic, the initial step is towards exploration and become familiar with the past research done on the subject. Literature review can be considered as the backbone on which the research concept stands as it provides the necessary context, reliability and the necessary background to the research idea. Thus Literature review is one of the most critical parts of any research. In today’s scenario Work life balance and glass ceiling is a major concern for the women who have opted to come out of their domestic chores and have chosen to work outside. Competition and challenges in the organization demands the time of women which they actually wanted to devote to their families. This imbalance can also create Glass ceiling preventing women from climbing hierarchical ladder. Review of literature on work-life balance and glass ceiling of women employees has been carried out keeping in mind the objectives of the study. The researcher has reviewed the previous literature on various aspects related to work-life balance (WLB). Review on the Glass Ceiling is also focused in this paper. The main purpose of this paper is to find out the gap and the need to conduct this research. The source of the study includes various Journals, reports, Books, Doctoral thesis, Internet sites and Magazines.
Good to Bad or Bad to Bad? What is the relationship between valence and the trait content of the Big Two?

In this article we directly assessed the relationship between valence and relevant traits of the Big Two dimensions (i.e., communion and agency). Drawing on previous research, we expected that the relationship with valence would be less monotonous and more variable in direction across agency-related traits, compared to communion-related traits. In three repeated measures studies we assessed the perceived valence of each trait dimension on a continuum of seven points. Studies 1 and 2 defined each continuum verbally. In Study 3 each continuum was defined by facial features. Results across these studies show that valence is linearly and more consistently related with communion-related traits than with agency-related traits. Within agency, however, competence established a positive linear relationship with valence, whereas dominance showed a target-sensitive relationship with valence: quadratic in evaluation of trait concepts, and negative and linear in face evaluation. We discuss the implications of these data for Big Two-related research.
Histopathologic Evaluation of Polymer Supports for Pintucci-type Keratoprostheses: An Animal Study

Abstract Purpose To report histopathological findings for different types of polymers proposed as support for a Pintucci-type keratoprosthesis. Methods Six polymers, including three types of polyesters (#1-3), one type of polytetrafluoroethylene (PTFE, #4), polyethylene (#5), and expanded polytetrafluoroethylene (ePTFE, #6) were evaluated. Four samples of each material were placed under the orbicularis oculi muscles of 12 rabbits. After five weeks, the samples were removed and evaluated histopathologically. Fibrovascular tissue ingrowths were investigated in terms of tissue penetration depth into the materials (graded as none, mild, moderate, and intense) and fibrovascular ingrowth area at the ultimate level of tissue penetrance. ImageJ software was used to calculate fibrovascular tissue area between the material fibers, and the mean area values were compared between the materials. Results Polyester materials #1 and #3 demonstrated intense fibrovascular tissue penetration with a large fibrovascular ingrowth area; no overt tissue ingrowth was observed into material #6. The mean area of penetrated fibrovascular tissues was significantly different between materials (P < 0.001). Materials #2, #4, and #5 showed moderate fibrovascular tissue ingrowth and the area of presented fibrovascular tissue at the paracentral parts of material #4 was significantly smaller than that of materials #1 (P = 0.02) and #3 (P = 0.01). Conclusion Two polyester materials that had relatively large pore sizes demonstrated a deep and large area of fibrovascular ingrowth. Given that material #3 is thicker and more consistent than material #1, the former can be used as the appropriate material for supporting the Pintucci-type keratoprosthesis.
Analysing trends in the spatio-temporal behaviour patterns of mainland Chinese tourists and residents in Hong Kong based on Weibo data

ABSTRACT Visiting tourists and residents of a city interact at various locations at various times. Previous studies paid little attention to comparing the spatio-temporal behaviours of tourists and residents from a long-term perspective. The aim of the present study was to identify and compare the spatio-temporal behaviours of mainland Chinese tourists and residents in Hong Kong over a period of five years. Their behaviours were compared by means of kernel density analysis and temporal statistical analysis, using Weibo geotagged check-in data and geographic information systems (GIS). The results show that the spatial behaviours of mainland Chinese tourists (MCT) are more concentrated than those of residents, especially in central urban areas, whereas residents also visit suburban and exurban areas. Simultaneously, MCTs’ temporal behaviours varied significantly, whereas those of residents were relatively stable. From a long-term perspective, we found that in the central urban area, MCTs’ preferences for locations tended to be relatively fixed, but their activity in local neighbourhoods and residential quarters decreased. However, residents’ interest in typical tourism highlights decreased reflecting potential strategies of avoidance in those areas whereas their activities in other tourism hotspots were more stable. These findings can be applied in urban planning, destination management and sustainable development.
LGBTQ2+ inclusive communities’ transformation through the arts

The Arts bring potential benefits for students (Bowen, Greene, & Kisida, 2014), especially LGBTQ2+ ones because it can help develop creativity, empathy, and self-expression, which is enormously important to LGBTQ2+ students. For the purpose of the research, LGBTQ2+ is an acronym for lesbian, gay, bisexual, transgender, two-spirit, queer, or questioning and intersex people who face mental and physical barriers to success in school communities. Therefore, creating LGBTQ2+ inclusive communities is paramount in order to connect these students with the schools in which they learn and give educators an insight into the LGBTQ2+ community. A qualitative data collection was done through semi-structured interviews. Two Canadian and three Vietnamese educators were recruited and participated in the study. Thematic data analysis of the transcribed interviews framed five key themes associated with LGBTQ2+ inclusive community and the Arts: i) professional experience in an LGBTQ2+ inclusive curriculum, ii) definition of a LGBTQ2+ inclusive community or classroom, iii) the powers of the arts, iv) art forms, and v) applying the arts to teaching practices. This study demonstrated how the transformational power of the arts in school communities and classroom curricula, and the uses of the arts in teaching practices, could embrace the idea of inclusiveness. The study supports the roles of the arts in social justice and the need for continuing support of LGBTQ2+ policies and practices in school communities. LGBTQ2+ INCLUSIVE COMMUNITIES’ TRANSFORMATION 3 ACKNOWLEDGEMENTS I would like to express my deepest sense of gratitude to Dr. Nadine Cruickshanks my thesis supervisor – who has listened to my stories, opened my heart to the world, encouraged me to speak my own voice and be proud of who I am, provided me with endless support and guidance along the way and, significantly, opened up a new horizon of the word “education” in me.

Once again, to these people, I would like to send my profound gratitude. LGBTQ2+ INCLUSIVE COMMUNITIES’ TRANSFORMATION 4
Colour segmentation of multi variants tuberculosis sputum images using self organizing map

Lung tuberculosis detection is still identified from Ziehl-Neelsen sputum smear images in low and middle countries. The clinicians decide the grade of this disease by counting manually the amount of tuberculosis bacilli. It is very tedious for clinicians with a lot number of patient and without standardization for sputum staining. The tuberculosis sputum images have multi variant characterizations in colour, because of no standardization in staining. The sputum has more variants colour and they are difficult to be identified. For helping the clinicians, this research examined the Self Organizing Map method for colouring image segmentation in sputum images based on colour clustering. This method has better performance than k-means clustering which also tried in this research. The Self Organizing Map could segment the sputum images with y good result and cluster the colours adaptively.
Weighing Words: The Impact of Non-victim Correspondence on Parole Board Decisions

Abstract Parole board members consider a number of behavioral, demographic, and criminogenic factors when making a decision to release a person from prison. The role of victims’ correspondence on such decision-making has also been examined, but less well understood is the role of non-victim correspondence, despite substantial evidence that social support networks are crucial to reentry success and reducing recidivism. Drawing upon a sample of 694 randomly selected cases involving men incarcerated in Iowa, the present study examines the relationship between non-victim correspondence and release decisions. Thirty-six percent of the sample had correspondence included in their parole hearing file with the majority written by family and friends, judicial actors, or correctional officers. Neither intensity of correspondence, the persuasion, nor the identities of non-victim authors were significantly associated with release decision in multivariate modeling. Instead, correctional counselor recommendation, risk assessment, and race emerged as significant factors in directing parole board member decision-making.
Robust Power Control of Optical Networks with Time-delays

Robust Power Control of Optical Networks with Time-Delays Nemanja Stefanovic Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto 2010 We study the stability of power control algorithms applied to optical networks in the presence of both time-delays and uncertainties. The objective of power control algorithms acting on optical networks is to ensure each signal channel attains an optimal optical signal-to-noise ratio (OSNR) value such that transmission errors are minimized. The inputs to the optical network are the transmitter powers and the outputs of the optical network are the OSNR values. The primal control algorithms adjust the channel powers at the transmitters using the channel OSNR values as feedbacks to attain OSNR optimality. We also present the dual control algorithm located at the links which transmits a channel price as an additional feedback to the primal control algorithms. Together, these are called primal-dual control algorithms. We present robust OSNR models for optical networks with multiple time-delays. Specifically, we consider additive system uncertainties, input multiplicative uncertainties on the signal powers, and transmitter noise uncertainties, all within a norm-bounded uncertainty framework. We analyze and modify both central cost based algorithms and game-theoretic based algorithms, with an emphasis on the latter, to ensure the stability of the closed-loop system. We apply time-delay stability analyses to exploit the structures of the closed-loop systems for each type of control algorithm. These techniques include frequency analyses, Lyapunov-Razumikhin techniques, and Lyapunov-Krasovskii techniques. Due to nonlinearities in the closed-loop system models, and their time-scale ii separated dynamics, we apply singular perturbation theory modified to handle either Lyapunov-Razumikhin theory or Lyapunov-Krasovskii theory. Singular perturbation theory, modified for time-delays, allows us to decouple complicated closed-loop systems into two simpler subsystems, one on a ”slow” time-scale, and the other on a ”fast” time-scale. We develop stability conditions for primal algorithms applied to arbitrary networks with delays. We also develop stability conditions for primal-dual algorithms applied to singlelinks, single-sink networks, two channel networks, and multi-link networks with both time-delays and uncertainties. The main results are presented as either LMI conditions and algebraic criteria. Simulations verify the stability of the closed-loop systems in the presence of time-delays. In addition, the simulations show the stabilization of perturbed systems at the expense of transient convergence time.
Is Women's Job Satisfaction Higher than Men's? Self-Selection, Expectations or Utility Function

This paper examines the paradox between high relative levels of job satisfaction and the characteristics of women's jobs compared to men's in Spain. Three hypothesis are considered: i) the existence of a selection bias when participating in the labour market; ii) of the presence of adaptive job satisfaction; and iii) the existence of differences related to preferences of different nature to strictly labour issues. The study shows that, although having lower working conditions, women are more likely to be satisfied at work than men are. This paradox persists regardless of the inclusion of a great range of variables of different nature (objective and subjective), the age group and educational level under consideration. The Oaxaca-Blinder decomposition suggests that women's preferences are actually influencing the differences in job satisfaction. However, it is not demonstrated that these differences disappear as age decreases or educational level increases. The probable existence of a “glass ceiling” that prevents women from having access to posts of greater responsibility and higher wages could cause that women who actually reach them are more satisfied than their male colleagues. As the labour market and society become more equal, this paradox might dilute.
