The purpose of this paper is to understand the effect of basin water depth towards the cumulative distillate yield of the traditional and developed single basin double slope solar still (DSSS).

Modified single basin DSSS integrated with solar operated vacuum fan and external water cooled condenser was fabricated using aluminium material. During sunny season, experimental investigations have been performed in both conventional and modified DSSS at a basin water depth of 3, 6, 9 and 12 cm. Production rate and cumulative distillate yield obtained in traditional and developed DSSS at different water depths were compared and best water depth to attain the maximum productivity and cumulative distillate yield was found out.

Results indicated that both traditional and modified double SS produced maximum yield at the minimum water depth of 3 cm. Cumulative distillate yield of the developed SS was 16.39%, 18.86%, 15.22% and 17.07% higher than traditional at water depths of 3, 6, 9 and 12 cm, respectively. Cumulative distillate yield of the developed SS at 3 cm water depth was 73.17% higher than that of the traditional SS at 12 cm depth.

Performance evaluation of DSSS at various water depths by integrating the combined solar operated Vacuum fan and external Condenser.

The role of chief executive officer (CEO) personal characteristics in shaping corporate policies has attracted increasing academic attention in the past two decades. In this review, the authors synthesize extant research on CEO attributes by reviewing 232 articles published in 29 journals from the accounting, finance and management literature. This review provides an overview of existing findings, highlights current trends and interdisciplinary differences in research approaches and identifies potential avenues for future research.

To review the literature on CEO attributes, the authors manually collected peer-reviewed articles in accounting, finance and management journals from 2000 to 2021. The authors conducted in-depth analysis of each paper and manually recorded the theories, data sources, country of study, study period, measures of CEO attributes and dependent variables. This procedure helped the authors group the selected articles into themes and sub-themes. The authors compared the findings in various disciplines and provided direction for future research.

The authors highlight the role of CEO personal attributes in influencing corporate decision-making and firm outcomes. The authors categorize studies of CEO traits into three main research themes: (1) demographic attributes and experience (including age, gender, culture, experience, education); (2) CEO interactions with others (social and political networks) and (3) underlying attributes (including personality, values and ideology). The evidence shows that CEO characteristics significantly affect a wide range of specific corporate policies that serve as mechanisms through which individual CEOs determine firm success and performance.

CEO selection is one of the most crucial decisions made by corporations. The study findings provide valuable insights to corporate executives, boards, investors and practitioners into how CEOs’ personal characteristics can impact future firm decisions and outcomes that can, in turn, inform the high-stake process of CEO recruitment and selection. The study findings have significant practical implications for corporations, such as contributing to executive training programs, to assist executives and directors attain a greater level of self-awareness.

Building on the theoretical foundation of upper echelons theory, the authors offer an integrated theoretical framework to consolidate existing empirical research on the impacts of CEO personal attributes on firm outcomes across accounting and finance (A&F) and management literature. The study findings provide a roadmap for scholars to bridge the interdisciplinary divide between A&F and management research. The authors advocate a more holistic and multifaceted approach to examining CEOs, each of whom embodies a myriad of personal characteristics that comprise their unique identity. The study findings encourage future researchers to expand the investigation of the boundary conditions that magnify or moderate the impacts of CEO idiosyncrasies.

Homelessness has many causes and also is stigmatized in the United States, leading to much misunderstanding of its causes and what policy solutions may ameliorate the problem. The problem is of course getting worse and impacting many communities far removed from the West Coast cities the authors examine in this study. This analysis examines the socioeconomic variables influencing homelessness on the West Coast in recent years. The authors utilize a panel fixed effects model that explicitly includes measures of healthcare access and availability to account for the additional health risks faced by individuals who lack shelter. The authors estimate a spatial error model (SEM) in order to better understand the impacts that systemic shocks, such as the COVID-19 pandemic, have on a variety of factors that directly influence productivity and other measures of welfare such as income inequality, housing supply, healthcare investment, and homelessness.

The purpose of this paper is to study the spillover effects of foreign direct investment (FDI) on skilled–unskilled wage inequality in the Indian manufacturing industries.

The authors show theoretically with a model of spillover that if foreign firms (receiving FDI) have a negative spillover effect on domestic firms (not receiving FDI), then the level of capital and skilled workers in the domestic firms falls down. Consequently, the authors conduct an empirical analysis by using system GMM estimation technique on the firm-level data of the Indian organised manufacturing sector.

The authors show that wage inequality worsens when there is negative spillover effects like competition spillover or skill spillover effect of FDI in India.

To the best of the authors’ knowledge, this is the first attempt to measure the various spillover effects of FDI on the wage inequality in the Indian manufacturing industries by using firm-level data.

The practice of public relations (PR) is shaped by the ‘life world’ of the professionals; moreover, both the experiences of the professionals and societal changes shape the profession in a particular area (Hodges, 2006). Women have always played an important part in the development of PR as a profession and academic field in Turkey. Since PR Association of Turkey was established in 1972, five out of eight presidents have been women, and most of the members are also female. Female PR practitioners represent 70% of the total workforce of PR sector in Turkey, and most of the communication agencies are led by female entrepreneurs.

However, research on women' positions and their multiple roles in PR in Turkey are limited.

This chapter uses a qualitative study with 27 in-depth one-on-one interviews conducted in order to analyse female PR practitioners' experiences related to (1) the start of their careers, (2) their career experiences, (3) their evaluation of the profession, and lastly (4) their career goals. The interviewees included agency owners, managers, deputy general managers and group directors.

The research aimed to discover the female PR professional experience in respect of the difficulties they face in their practice and everyday life, advantages and/or disadvantages of being a female PR professional in Turkey and the ways women balanced their career and family duties.

This article explores whether six broad categories of activities undertaken by Canadian business scholars’ academics: publications record, citations record, teaching load, administrative load, consulting activities, and knowledge spillovers transfer, are complementary, substitute, or independent, as well as the conditions under which complementarities, substitution and independence among these activities are likely to occur.

A multivariate probit model is estimated to take into account that business scholars have to consider simultaneously whether or not to undertake many different academic activities. Metrics from Google Scholar of scholars from 35 Canadian business schools, augmented by a survey data on factors explaining the productivity and impact performances of these faculty members, are used to explain the heterogeneities between the determinants of these activities.

Overall, the results reveal that there are complementarities between publications and citations, publications and knowledge spillovers transfer, citations and consulting, and between consulting and knowledge spillovers transfer. The results also suggest that there are substitution effects between publications and teaching, publications and administrative load, citations and teaching load, and teaching load and administrative load. Moreover, results show that public and private funding, business schools’ reputation, scholar’s relational resources, and business school size are among the most influential variables on the scholar’s portfolio of activities.

This study considers simultaneously the scholar’s whole portfolio of activities. Moreover, the determinants considered in this study to explain scholars’ engagement in different activities reconcile two conflicting perspectives: (1) the traditional self-managed approach of academics, and (2) the outcomes-focused approach of university management.

The scarcity of women in advertising creative departments has been reported globally, particularly in creative managerial roles. This study goes a step beyond this evidence since this paper aims to test whether having at least one token woman in creative managerial positions (token+) may be associated with a larger presence of females in low-level creative jobs compared to creative departments led only by male creative managers.

A content analysis of the credit forms of 839 Spanish campaigns released in 2019 was conducted to determine the gender composition of 116 creative departments with more than three professionals.

Generalized Poisson Regressions indicated that when at least a token woman is present in a creative management role within agency networks, the number of females in low-level positions doubles with respect to creative departments led only by male managers. This relation was not found for independent agencies, though. The results are discussed under the lens of critical mass theory, attraction paradigm and homophily theory.

To the best of the authors’ knowledge, it is the first time in the literature that the relation among the number of token+ advertising female creative managers and the amount of females in lower-level creative positions is tested. This research is also original because the sample is from a non-Anglo-Saxon country. Moreover, the use of the Generalized Poisson Regressions technique is another novelty of this paper.

The purpose of this paper is to develop a framework to facilitate early supplier involvement (ESI) as an approach for reducing construction waste (CW) generated during the design process.

A research methodology consists of literature review, case studies and survey questionnaire was designed to achieve the abovementioned aim. First, the literature review was used to investigate CW, CW generated during the design process, the design process and ESI. Second, two construction projects were analysed to investigate the role of ESI towards reducing CW generated during the design waste. Third, a survey questionnaire was carried out with a representative sample of architectural design firms (ADFs) in Egypt to examine their perception and application of ESI towards reducing CW generated during the design process. Based on the results of the above, the research developed a framework to facilitate ESI during the design process to reduce CW.

Through literature review, the research highlighted the causes of CW generated during the design process and identified the benefits and challenges that encounter ESI in ADFs. Results of data analysis showed that “last-minute changes due to client requirements” was ranked the highest challenges of ESI in ADFs in Egypt followed by “lack of design experience”. Moreover, “providing technical information about materials and equipment and their capabilities” was ranked by respondents as the highest contributions of suppliers during the design process which leads to waste reduction followed by “better estimation of materials and costs”. Finally, respondents stated that “resistance of ADFs to include suppliers in the design phase” was ranked the highest challenge of ESI in the design process followed by “no clear guidelines or policies that organise ESI”.

Because of the conceptual nature of the proposed framework, it has to be tested and validated to ensure its capability to overcome the challenges of ESI as an approach for reducing CW generated during the design process.

This research presents a practical solution to the problem of CW generated during the design process through ESI.

The research discussed the causes of CW originated from the design process and the benefits and challenges of ESI in ADFs. It investigated the perception and application of ESI in ADFs in Egypt. The proposed framework which was designed to facilitate the integration of suppliers in the early stages of the project life cycle represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.

This study aims to address the effects of self-esteem and affective commitment on firm performance and whether these effects vary according to the gender and age of active entrepreneurial students.

This study uses a subsample from the Global University Entrepreneurial Spirit Students’ Survey (GUESSS) of entrepreneur students running their own businesses to perform a structural equation model (SEM) analysis to test the relationship between self-esteem (SE), affective commitment (AC) and firm performance (FP) moderated by the gender and age of entrepreneur students.

The results confirm that higher levels of entrepreneur SE are related to a higher assessment of AC and FP. A major effect of SE on AC was also observed among male respondents. Age was not related to an increase in AC. The effect of SE on AC and FP was lower among older students.

This study makes valuable contributions to the fields of entrepreneurship, psychology, gender and organizational behavior. This study presents empirical support for the theoretical framework using SEM, presenting initial insights into the mechanisms that shape AC in entrepreneurial students and its implications for FP.

Esta investigación tiene como objetivo analizar la influencia del género, la edad y la autoestima (SE) de los emprendedores en el compromiso afectivo (AC) de los estudiantes universitarios con sus emprendimientos y cómo se relacionan con el desempeño subjetivo de la empresa (FP).

Utilizamos los datos de la encuesta GUESSS de 2018 para realizar un modelo de ecuaciones estructurales (SEM) para determinar los efectos directos del género, la edad y la SE en el AC, sus efectos directos e indirectos en el FP y los efectos directos y papel mediador del AC hacia el FP, para estudiantes emprendedores.

Los resultados confirman que niveles más altos de SE están relacionados con niveles más altos de AC de los emprendedores a sus emprendimientos y una mayor evaluación de FP. Además, los hombres reportan niveles más altos de AC y FP que sus contrapartes femeninas, al tiempo que el género tiene un efecto importante en la relación del SE en el AC. La edad no está relacionada con el aumento del AC, pero el efecto de la SE sobre el AC disminuye con el incremento de la edad, y los valores de FP también se reducen para los estudiantes mayores en comparación con los estudiantes más jóvenes. Los niveles más altos de AC están relacionados con valores más altos de FP, y existe un efecto de mediación de AC para el género y SE sobre FP.

este estudio proporciona valiosas contribuciones a los campos del emprendimiento, la psicología, el género y el comportamiento organizacional. Primero, presentamos un marco teórico que integra postulados de emprendimiento FP, AC, SE, edad y género. Luego, probamos empíricamente nuestro marco teórico utilizando SEM y presentamos resultados iniciales sobre los mecanismos que dan forma al AC en estudiantes emprendedores y sus implicaciones para el FP.

Esta pesquisa tem como objetivo analisar a influência do gênero, da idade e da autoestima (SE) dos empreendedores no comprometimento afetivo (AC) dos universitários com seus empreendimentos e como eles se relacionam com o desempenho subjetivo da empresa (FP).

Utilizamos dados da pesquisa GUESSS de 2018 para realizar uma modelagem de equações estruturais (SEM) para determinar os efeitos diretos de gênero, idade e SE na AC, seus efeitos diretos e indiretos no FP e os efeitos diretos e papel mediador do AC na FP, para estudantes empreendedores.

Os resultados confirmam que níveis mais elevados de SE estão relacionados com níveis mais elevados de AC dos empreendedores para os seus empreendimentos e uma maior avaliação do FP. Além disso, os homens relatam níveis mais elevados de AC e FP do que as mulheres, embora tenham um efeito importante da SE na AC. A idade não está relacionada com o aumento da AC, mas o efeito do SE na AC diminui com o aumento da idade, e os valores de FP também diminuem para os alunos mais velhos em comparação com os alunos mais jovens. Níveis mais elevados de AC estão relacionados a valores mais elevados de FP, e há efeito mediador da AC para gênero e SE sobre FP.

Este estudo fornece contribuições valiosas para as áreas de empreendedorismo, psicologia, gênero e comportamento organizacional. Primeiro, apresentamos um quadro teórico que integra postulados de empreendedorismo em FP, AC, SE, idade e género. Em seguida, testamos empiricamente o nosso enquadramento teórico utilizando SEM e apresentamos resultados iniciais sobre os mecanismos que moldam o AC em estudantes empreendedores e as suas implicações para o FP.

The purpose of this study is to describe latent classes explaining the innovation logic in the Finnish construction companies. Innovativeness is a driver of competitive performance and vital to the long-term success of any organisation and company.

Using finite mixture structural equation modelling (FMSEM), the authors have classified innovation logic into latent classes. The method analyses and recognises classes for companies that have similar logic in innovation activities based on the collected data.

Through FMSEM analysis, the authors have identified three latent classes that explain the innovation logic in the Finnish construction companies – LC1: the internal innovators; LC2: the non-innovation-oriented introverts; and LC3: the innovation-oriented extroverts. These three latent classes clearly capture the perceptions within the industry as well as the different characteristics and variables.

The presented latent classes explain innovation logic but is limited to analysing Finnish companies. Also, the research is quantitative by nature and does not increase the understanding in the same manner as qualitative research might capture on more specific aspects.

This paper presents starting points for construction industry companies to intensify innovation activities. It may also indicate more fundamental changes for the structure of construction industry organisations, especially by enabling innovation friendly culture.

This study describes innovation logic in Finnish construction companies through three models (LC1–LC3) by using quantitative data analysed with the FMSEM method. The fundamental innovation challenges in the Finnish construction companies are clarified via the identified latent classes.
