Is outsourcing better? Clients' views on contracting in domestic cleaning services
Authors: du Toit David , Heinecken Lindy 
Published: February 2021

PurposeThe nature of paid domestic work is changing, with the growth in companies delivering domestic cleaning services. Few studies have looked at why people opt to use these services and the underlying drivers. As with the outsourcing of non-core tasks in businesses, outsourcing domestic work is motivated by similar, yet different reasons, which have to do with the personal and private nature of domestic employment. This study aims to establish the reasons why “clients”, who were former employers of domestic servants, opted to outsource domestic work to a domestic cleaning service provider.Design/methodology/approachGiven the limited research on domestic cleaning services in South Africa, a mixed-methods research approach is used.FindingsThe findings showed that there are three key motivations: the nature of the domestic cleaning service supplier, the services rendered by domestic workers and the tripartite employment relationships. These three benefits imply that clients have access to functional and numerical flexibility, unlike employing a domestic worker directly. This study contributes to the literature on outsourcing and domestic work by showing that clients not only look to change the economic structure of the relationship with domestic workers, but it allows them to psychologically and emotionally distance themselves from domestic workers.Research limitations/implicationsThis study shows that some people are no longer willing to have a relationship with the people who clean their homes, and that they believe it is simply not worth the effort to maintain a relationship. This is an aspect that needs further research, as this is the one sphere where women are united in their plight, albeit from different worldviews. Thus, a limitation is that this study only focuses on clients' views of outsourcing. Have domestic workers employed by the outsourced domestic cleaning service supplier become just like assembly-line workers, where they are anonymous to their clients, performing routine tasks with little recognition from those whose homes they are servicing? Future studies could focus on domestic workers' views on outsourcing and the effects it has on their working conditions and employment relations.Originality/valueFirstly, studies mainly focus on the Global North where domestic work and outsourcing have different dynamics, regulation policies and social changes when compared to South Africa. Secondly, few studies have sought to establish why people shift from employing a domestic or care worker directly to an outsourced domestic agency when direct domestic help is available and affordable. Considering these shortcomings, this study aims to provide a better understanding of domestic cleaning service suppliers from the perspective of clients, often omitted from the literature. Accordingly, this study aimed to establish what the benefits are for clients (former employers of domestic workers) who use domestic cleaning service suppliers.
Strive towards a good performance or avoid a failure performance in entrepreneurship education: a look into growth and independence-oriented intentions

Published: February 2021

PurposePrior studies on entrepreneurial intention have shown that different orientations exist regarding entrepreneurial engagement: one looking at the growth of a venture (growth-oriented) and the other looking at the maintenance of an entrepreneurial autonomy (independence-oriented). Filling a gap in the literature concerning the reasons why individuals develop different orientations of entrepreneurial intention, this study revolves around achievement goal motivation (mastery, performance and avoidance approaches) and self-regulatory modes (locomotion and assessment), since both are thought to be at the origin and maintenance of an action willingness.Design/methodology/approachIn a sample of 209 undergraduates, we administered a structured questionnaire at the beginning of an elective entrepreneurship education programme. Through a set of hierarchical regressions we examined the specific role of achievement goal motivation and regulatory modes in relation to the two orientations of intention.FindingsOur findings show that, on the one hand, growth-oriented intention is related to a performance approach and both locomotion and assessment regulatory modes. On the other hand, independence-oriented intention is related to an avoidance approach.Research limitations/implicationsThese results illuminate the theoretical connections between entrepreneurial intention and motivation and provide implications for entrepreneurship education and the relationship between intention and consequent behaviour.Originality/valueThis study is among the first to provide an empirical exploration of the motivational and regulatory drivers that lie beneath a growth-oriented and an independent-oriented intention, offering a theoretical explanation about the development of different intentions towards venture creation. Our findings illuminate on the urgency to consider entrepreneurial intention as a multi-dimensional construct if we are to understand the intention-behaviour nexus.

Authors: Burhan Mukaddes , Cakir Serhat 
Published: February 2021

PurposeThe purpose of this paper is to provide information about the long-term ex-post impacts of Vision 2023 technology foresight (TF) on the defense sector and to identify critical success factors (CSFs) of impactful foresight.Design/methodology/approachIn the present research, a theory-based evaluation approach was adopted with the logic-model of defense TF to identify the intended outcomes, impacts and leading mechanisms. The impact assessment framework developed by Johnston, R. (2012) was adopted to identify (un)intended impacts and possible measures.FindingsTF had some effects on technological developments, foresight capacity and capability and skills on the sector. The overall impact was assessed at the “some contribution” level with 2.9 out of 5.0 points. It contributed to the development of science technology and innovation (STI) policies and research and development programs, awareness-raising in STI, increase in cooperation between government-university-industry and the development of foresight culture. However, the impacts were more visible in the early years of TF. Additionally, country/sector-specific CSFs were identified. In consequence, it was proposed to measure the maturity of strategic technologies with technology readiness level as a tangible indicator.Originality/valueAccording to the authors, this is the first study to assess the long-term ex-post impact of TF in defense. An instrument was developed to assess TF’s contribution to impact measures. The constructs and weights of the instrument differentiated from the adopted framework/schema reflecting the national/sectoral context of TF. Additionally, the study revealed country/sector-specific CSFs and new tangible impact measures.
First price sealed-bid auction of the grey game improvement model via double-parameter Bayesian estimation
Authors: Deng Fei , Liu Sifeng , Fang Zhigeng 
Published: February 2021

PurposeThe improved classical model makes it possible that the evaluation strategy has an optimal tendency, which reveals the purpose of this paper is to facilitate the first price sealed-bid auction more in line with the actual situation. To be more specific, there are several merits in the improvement process. On the one hand, the bid-winning probability can be improved for the bidder; on the other hand, the real market value of the subject matter can be more clearly recognized for the employer.Design/methodology/approachBayesian estimation and grey system theory are referenced in this paper, with the use of double-parameter estimation, little historical data and expert experience. Specific implementation steps are as follows: first of all, using the double-parameter Bayesian estimation to correct the actual valuation of the bid matter v, then introducing the threat factor grey number R in the auction model, giving the improving of the optimal grey quotation and grey expectation utility under the two-party game and finally taking the aerospace component procurement as an example, simulating the bidding process of the bidding parties to arrive at the optimal bid strategy.FindingsThe improved model shows that the optimal strategy will change with the threat factor rather than a fixed value. When the threat factor grey number R follows [0.4, 0.6], the optimal quotation strategy will appear, which means quotation is higher than 50% of the bid matter's valuation.Practical implicationsThe improved model proposed in this paper can strengthen the cost control in the Chinese commercial space process and optimize the pricing strategy for the final launch.Originality/valueThe modified model changes the habit that the bidder's valuation of the bid subject to mainly come from experience and to prompt the model for making full use of little historical data on the foundation of the former. It can reduce the subjective judgment error in the game results; finally, the practical cases are simulated in MATLAB at the same time, and the simulation effect is good, so we can get some more realistic conclusions on this basis.

Authors: Nanayakkara Janandani , Margerison Claire , Worsley Anthony 
Published: February 2021

PurposeTeachers play important roles in school food and nutrition education. This study aims to explore Australian teachers' self-efficacy beliefs (i.e. belief in their own capabilities to perform specific teaching tasks) in teaching secondary school food and nutrition-related subjects.Design/methodology/approachTeachers' overall self-efficacy beliefs in teaching these subjects (overall-SEB) and self-efficacy beliefs in teaching different food and nutrition-related topics (topics-SEB) were explored using a survey among 183 teachers in 2017. Principal components analysis derived three overall-SEB components: “Motivation and accommodation of individual differences”, “Classroom management” and “Communication and clarification” and three topics-SEB components: “Food system”, “Food and nutrition information” and “Food preparation”.FindingsOverall, higher percentages of teachers were confident or very confident in the majority of items that loaded on “Classroom management” and “Communication and clarification” compared to “Motivation and accommodation of individual differences”. Moreover, higher percentages of teachers were confident or very confident about items that loaded on “Food and nutrition information” and “Food preparation” compared” to “Food system”. The overall-SEB and topics-SEB were higher among more experienced teachers. There were moderate positive correlations between overall-SEB and topics-SEB components.Originality/valueThe exploration of broader aspects of self-efficacy beliefs related to teaching secondary school food and nutrition-related subjects makes this study unique. The findings highlight that these teachers had high self-efficacy beliefs in teaching food and nutrition education, but there are gaps in tailoring the teaching process to meet the diverse needs of students and teaching broader food-related topics.
The role of principals in school health promotion in South Africa: a qualitative study
Authors: Kwatubana Siphokazi , Nhlapo Velaphi Aaron , Moteetee Nomsa 
Published: February 2021

PurposeSchool principals are presumed to be pillars of school health promotion implementation. Their understanding of their role could enhance school health promotion. This study aims to investigate how principals understood their role in school health promotion.Design/methodology/approachIn this study, semi-structured interviews were conducted with six school principals who participated and completed the first cycle of the Continuous Professional Teacher Development programme that was offered by the South African Council of Educators. Snowball sampling was used to sample participants.FindingsThe findings of this study showed that principals did not differentiate between concepts of health-promoting schools and school health promotion, the meaning was the same for them. They focused on any health improvement within the schools, regardless of its conceptual nature. The second finding pertains to the role of the principal as a manager, while the third was on expedition of collaborations and partnerships.Research limitations/implicationsThis research was limited to school principals who completed the Continuous Professional Teacher Development programme. It, therefore, does not include perceptions of other principals.Originality/valueThe study findings suggest that despite inability of schools in poor communities to implement effective school health programmes, the principals of the sampled schools were aware of their roles. This is positive, as the efforts to enhance health promotion initiatives would focus on developing and empowering principals to improve their performance.

Authors: Trisnowati Heni , Ismail Djauhar , Padmawati Retna Siwi 
Published: February 2021

PurposeThis paper aimed to review globally the empowerment programs for the prevention and control of smoking behavior among youths, to examine the role of empowerment in health promotion, to explore the stages of health promotion through community empowerment strategies including planning, implementation and evaluation. Finally, this paper will develop a model of youth empowerment to prevent and control smoking behavior that reflects theory and experience drawn from the literature.Design/methodology/approachThis review synthesized articles on community empowerment and health promotion, youth empowerment programs for tobacco prevention and control globally from books and electronic databases from the Universitas Gadjah Mada (UGM) library in the publication period 2000–2020. Relevant literature was selected and critically reviewed which reflected the role empowerment in health promotion, stage of community empowerment strategy as described by Laverack and youth empowerment concept in tobacco control as described by Holden.FindingsDocuments that specifically discuss empowerment programs for smoking prevention and control are still limited. The findings document that youth empowerment in tobacco control do not fully integrate the theory empowerment as described by Laverack and Holden. This paper provides information about the stages of youth empowerment, and a conceptual framework of youth empowerment for the prevention and control of smoking behavior. Youth empowerment is done through the direct involvement of youth in programs starting from program design, planning, implementation and evaluation. Indicators of the success of the empowerment process are reflected in the increase in the empowerment domain. Meanwhile, the output of empowerment can be seen from the individual- or group-level changes.Originality/valueThis paper proposes a model of youth empowerment for the prevention and control of smoking behavior among youths based on theory and experience in the field.

Asian scholars are recommended to increase cooperation and exchanges with each other, expand channels of contact, further understand and optimise their own advantages, achieve win-win cooperation and make Asia's voice heard in the world in higher education field.Originality/valueThis bibliometric review can predict the main trends in higher education internationalisation in the future and encourage implication of interdisciplinary research in higher education internationalisation.
Calculation and analysis of thermal flow field in hydrodynamic torque converter with a new developed stress-blended eddy simulation
Authors: Yang Konghua , Liu Chunbao , Li Jing , Xiong Jiawei 
Published: February 2021

Purpose
The flow phenomenon of particle image velocimetry has revealed the transition process of the complex multi-scale vortex between the boundary layer and mainstream region. Nonetheless, present computational fluid dynamics methods inadequately distinguish the discernable flows in detail. A multi-physical field coupling model, which was applied in rotor-stator fluid machinery (Umavathi, 2015; Syawitri et al., 2020), was put forward to ensure the identification of multi-scale vortexes and the improvement of performance prediction in torque converter.

Design/methodology/approach
A newly-developed multi-physical field simulation framework that coupled the scale-resolving simulation method with a dynamic modified viscosity coefficient was proposed to comparatively investigate the influence of energy exchange on thermal and flow characteristics and the description of the flow field in detail.

Findings
Regardless of whether quantitative or qualitative, its description ability on turbulence statistics, pressure-streamline, vortex structure and eddy viscosity ratio were visually experimentally and numerically analyzed. The results revealed that the modification of transmission medium viscous can identify flows more exactly between the viscous sublayer and outer boundary layer. Compared with RANS and large eddy simulation, a stress-blended eddy simulation model with a dynamic modified viscosity coefficient, which was further used to achieve blending on the stress level, can effectively solve the calculating problem of the transition region between the near-wall boundary layer and mainstream region.

Research limitations/implications
This indeed provides an excellent description of the transient flow field and vortex structure in different physical flow states. Furthermore, the experimental data has proven that the maximum error of the external performance prediction was less than 4%.

Originality/value
An improved model was applied to simulate and analyze the flow mechanism through the evolution of vortex structures in a working chamber, to deepen the designer with a fundamental understanding on how to reduce flow losses and flow non-uniformity in manufacturing.
Unsteady stagnation-point flow of upper-convected Oldroyd-B nanofluid with variable thermal conductivity and relaxation-retardation double-diffusion model
Authors: Bai Yu , Wang Qing , Zhang Yan 
Published: February 2021

Purpose
This paper aims to examine the unsteady stagnation-point flow, heat and mass transfer of upper-convected Oldroyd-B nanofluid along a stretching sheet. The thermal conductivity is taken in a temperature-dependent fashion. With the aid of Cattaneo–Christov double-diffusion theory, relaxation-retardation double-diffusion model is advanced, which considers not only the effect of relaxation time but also the influence of retardation time. Convective heat transfer is not ignored. Additionally, experiments verify that with sodium carboxymethylcellulose (CMC) solutions as base fluid, not only the flow curve conforms to Oldroyd-B model but also thermal conductivity decreases linearly with the increase of temperature.

Design/methodology/approach
The suitable pseudo similarity transformations are adopted to address partial differential equations to ordinary differential equations, which are computed analytically through homotopy analysis method (HAM).

Findings
It is worth noting that the increase of stagnation-point parameter diminishes momentum loss, so that the velocity enlarges, which makes boundary layer thickness thinner. With the increase of thermal retardation time parameter, the nanofluid temperature rises that implies heat penetration depth boosts up and the additional time required for nanofluid to heat transfer to surrounding nanoparticles is less, which is similar to the effects of concentration retardation time parameter on concentration field.

Originality/value
This paper aims to explore the unsteady stagnation-point flow, heat and mass transfer of upper-convected Oldroyd-B nanofluid with variable thermal conductivity and relaxation-retardation double-diffusion model.

Authors: Bordbar Gholamreza , Konjkav Monfared Amirreza , Sabokro Mehdi , Dehghani Niloofar , Hosseini Elahe 
Published: February 2021

Purpose
The purpose of this paper is standardize and provide a multidimensional measure for assessing human resources competencies (HRCs) scale.

Design/methodology/approach
The data collected in this study were 2018 from the 234 people selected from 603 managers and experts in human resources of selected firms existing in the Yazd Industrial Town randomly. Based on the model of HRCs designed by Ulrich et al. (2008), a questionnaire was developed to assess HRCs. Internal consistency and split-half methods were used to obtain the reliability of the instrument. Content validity and construct validity of the instrument were also assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

Findings
This paper elucidates a key scale for assessing HRCs including three dimensions: knowledge business, functional expertise and managing change. Also, results revealed that two items were then dropped from the questionnaire as they were unreliable, and a final 31 items were extracted to form the scale for assessing HRCs. The coefficients for Cronbach’s α and split-half were 0.963 and 0.947, respectively. In EFA, Kaiser-Meyer-Olkin test yielded optimal 0.962, and Bartlett’s test was statistically significant. Additionally, three factors with eigenvalues higher than 1 explained 63% of the total variance. Hence, CFA confirmed the results from EFA too. Moreover, the model proved to enjoy a good fit.

Practical implications
The scale is useful for both researchers and practitioners. Also, the scale provides researchers with a sought-after conceptualization of HRCs.

Originality/value
Consequently, considering that the validity and reliability indices of HRCs were estimated to be desirable, the authors believe that the developed questionnaire can be used as an appropriate scale for measuring HRCs in future research.
