Childcare is one of the main obstacles for women to enter the labour market as they are the primary caregivers for children. The struggle between childcare and women's employment has caused a high labour turnover in women-dominated industries. The aim of this study is to assess the employees’ willingness for an on-site childcare facility

The primary goal of this study was to assess the employees' willingness for an on-site childcare facility using the contingent valuation method. For the analysis, 330 data were collected from all levels of the employees in three firms in the apparel industry using a survey-based questionnaire.

The results illustrate that the mean willingness to pay for the on-site childcare facility is substantially higher for the firm that already provide an on-site childcare facility than the other two firms that do not have childcare facilities. Among all employees who are surveyed, 86.36% of the employees favoured implementation of on-site childcare facilities. According to the survey findings, the newly hired employees have a higher preference for the childcare facility, however less likely to pay for the facility. The monthly income variable has a negative association with the probability of voting in favour of implementing on-site childcare facility. Moreover, the results indicate that the employees who have received the childcare facility have positive attitudes towards the on-site childcare facility.

To the authors' knowledge, prior case studies related to the evaluation of employee's preference for on-site childcare services have not been conducted in the context of industries in Sri Lanka. Therefore, the findings and implications were discussed while expanding the geographical scope of the past literature.

The calculation of the shear capacity of inclined section for prestressed reinforced concrete beams is an important topic in the design of concrete members. The purpose of this paper, based on the truss-arch model, is to analyze the shear mechanism in prestressed reinforced concrete beams and establish the calculation formula for shear capacity.

Considering the effect of the prestressed reinforcement axial force on the angle of the diagonal struts and regression coefficient of softening cocalculation of shear capacity is established. According to the shape of the cracks of prestressed reinforced concrete beams under shear compression failure, the tie-arch model for the calculation of shear capacity is established. Shear-failure-test beam results are collected to verify the established formula for shear bearing capacity.

Through theoretical analysis and experimental beam verification, it is confirmed in this study that the truss-arch model can be used to analyze the shear mechanism of prestressed reinforced concrete members accurately. The calculation formula for the angle of the diagonal struts chosen by considering the effect of prestress is accurate. The relationship between the softening coefficient of concrete and strength of concrete that is established is correct. Considering the effect of the destruction of beam shear plasticity of the concrete on the surface crack shape, the tie-arch model, which is established where the arch axis is parabolic, is applicable.

The formula for shear capacity of prestressed reinforced concrete beams based on this theoretical model can guarantee the effectiveness of the calculation results when the structural properties vary significantly. Engineers can calculate the parameters of prestressed reinforced concrete beams by using the shear capacity calculation formula proposed in this paper.

This paper aims to identify the disproportionate impacts of the COVID-19 pandemic on labor markets.

The authors conduct a large-scale survey on 16,000 firms from 82 industries in Ho Chi Minh City, Vietnam, and analyze the data set by using different machine-learning methods.

First, job loss and reduction in state-owned enterprises have been significantly larger than in other types of organizations. Second, employees of foreign direct investment enterprises suffer a significantly lower labor income than those of other groups. Third, the adverse effects of the COVID-19 pandemic on the labor market are heterogeneous across industries and geographies. Finally, firms with high revenue in 2019 are more likely to adopt preventive measures, including the reduction of labor forces. The authors also find a significant correlation between firms' revenue and labor reduction as traditional econometrics and machine-learning techniques suggest.

This study has two main policy implications. First, although government support through taxes has been provided, the authors highlight evidence that there may be some additional benefit from targeting firms that have characteristics associated with layoffs or other negative labor responses. Second, the authors provide information that shows which firm characteristics are associated with particular labor market responses such as layoffs, which may help target stimulus packages. Although the COVID-19 pandemic affects most industries and occupations, heterogeneous firm responses suggest that there could be several varieties of targeted policies-targeting firms that are likely to reduce labor forces or firms likely to face reduced revenue. In this paper, the authors outline several industries and firm characteristics which appear to more directly be reducing employee counts or having negative labor responses which may lead to more cost–effect stimulus.

The morphology of a building describes its outline and influences its architectural aesthetics and the cost directly. However, the literature on the impact of morphology on the aesthetics and cost of urban detached residential buildings is scarce. Thus, this study is significant because its aim was to identify the critical building morphology factors and the relationship that each of them maintains with the cost and aesthetics of urban detached residential buildings.

The multi-method qualitative approach was used to collect the required empirical data through interviews and case studies and to identify the effect of the morphology factors on the aesthetics and construction cost of urban residences in Sri Lanka, respectively. The collected data were analyzed using manual content analysis and descriptive statistics.

The study findings revealed that the morphology factors such as the roof and circulation spaces, open spaces and voids have a high impact on both the building cost and aesthetics. These findings will assist building designers in making effective design decisions on building costs and aesthetics so that a successful design outcome satisfying both the clients and design team could be obtained.

Although morphology has an impact on the cost and aesthetic of buildings, literature on the subject is scarce. Thus, this study is significant in that it aimed at identifying the significant building morphology factors in urban detached residential buildings and identifying their relationship with the cost and aesthetic of those buildings.

The research aims to describe Sri Lanka's education system, discuss reforms that have been implemented within the school, university and vocational education sectors in the recent past and suggest potentially fruitful reforms whilst identifying the various constraints which can affect their implementation.

A descriptive approach is employed, with extensive review of related literature and the use of relevant secondary data where appropriate.

The research shows the need for considerable reform of Sri Lanka's education system, especially with regard to improving the quality of state education and encouraging greater private sector participation.

The research shows the deficiencies Sri Lanka's education system suffers from and suggests means to overcome them. However, the political and social pressures may present obstacles upon the implementation of such courses of action.

The recommendations offered by the research could make a contribution towards transforming the education system in Sri Lanka into one which can produce empowered individuals who can find employment within the emerging sectors of the economy and thereby improve overall living standards in the country.

The paper makes a novel contribution by encompassing school, tertiary and vocational education in Sri Lanka. It shows the numerous problems that could arise in a context where a universal system of free education from the primary to the tertiary level exists vis‐à‐vis a flourishing private sector, and would be of value to education policy‐planners in Sri Lanka and other countries with both state and private sector provision of education.

Acceptance sampling plans are designed to decide about acceptance or rejection of a lot of products on the basis of sample drawn from it. Accelerating the life test helps in obtaining information about the lifetimes of high reliability products quickly. The purpose of this paper is to formulate an optimum time censored acceptance sampling plan based on ramp-stress accelerated life test (ALT) for items having log-logistic life distribution. The log-logistic life distribution has been found appropriate for highly reliable components such as power system components and insulating materials.

The inverse power relationship has been used to model stress-life relationship. It is meant for analyzing data for which the accelerated stress is nonthermal in nature, and frequently used as an accelerating stress for products such as capacitors, transformers, and insulators. The method of maximum likelihood is used for estimating design parameters. The optimal test plan is obtained by minimizing variance of test-statistic that decides on acceptability or rejectibility of lot. The optimal test plan finds optimal sample size, stress rates, sample proportion allocated to each stress and lot acceptability constant such that producer’s risk and consumer’s risk is satisfied.

Asymptotic variance plays a pivotal role in determining the sample size required for a sampling plan for deciding the acceptance/rejection of a lot. The sample size is minimized by optimally designing a ramp-stress ALT so that the asymptotic variance is minimized.

The model suggested is of use to quality control and reliability engineers dealing with highly reliable items.

The paper aims to present acceptance sampling plans based on failure‐censored step‐stress accelerated life tests for items having Weibull lives.

The model parameters are estimated by the method of maximum likelihood. Based on asymptotic distribution theory, the sample size and the acceptability constant are determined satisfying the producer's and consumer's risks. The step‐stress accelerated life test is optimized to have a minimum sample size by minimizing the asymptotic variance of test statistic. Two modes of step‐stress accelerated life test are considered, and a comparison between them is made. The proposed sampling plans are compared with the sampling plans based on constant stress accelerated life tests.

Asymptotic variance is a dominating factor in determining the sample size required for a sampling plan to determine the acceptability of a lot. The sample size is minimized by optimally designing a step‐stress accelerated life test so that the asymptotic variance is minimized.

The sampling plans presented in this paper are particularly useful when items to be tested are so reliable and are useful to reliability engineers and life test planners.

Scholars have argued that it is important to investigate how authentic leadership is manifested in different cultures (Avolio et al., 2005; Gardiner, 2011; Shamir and Eilam, 2005). Hence the purpose of this paper is to capture a cross-cultural view of authentic leadership, using a sample of South Asian leaders.

Because of a dearth of qualitative empirical evidence, the authors adopted a “life story” approach to collect data. A total of 14 leaders from India, Nepal, Pakistan and Sri Lanka were interviewed to share their leadership experiences.

Findings indicate that the concept of authentic leadership is culturally relevant. It emerged as a multi-dimensional construct constituting self-concept, follower development, organizational outcomes and culture (Meacham, 2007), and contextual knowledge. The authors propose a cross-cultural model of authentic leadership.

Research limitations include researchers’ possible biases in design of data and an assumption that leaders interviewed were authentic. Despite these limitations, the study provides valuable insights about authentic leadership to strengthen its theoretical foundation.

Organizational and social problems in South Asian are often attributed to a leadership deficit (Khan, 2014; Khilji, 2013; National Post, 2014; Sardesai, 2013). This study provides evidence of transformative authentic leaders in South Asia who are engaged with their and followers’ authentic growth, and are building authentic cultures for positive organizational outcomes.

The value of the present research is in providing qualitative empirical evidence from South Asia, and proposing a cross-cultural model of authentic leadership.

The purpose of this paper is to explore and analyse the extent to which socio‐political obstacles have influenced the successful establishment and performance of an institutional framework to implement the privatization programme in Sri Lanka.

Secondary data have been extensively used in this paper to interpret, analyse and strengthen the arguments. Further, the recent data collected through semi‐structured interviews with stakeholders in the telecommunications sector in Sri Lanka have been used. The analysis has been confined to the Sri Lankan context.

This paper finds that the institutional framework, one of the preconditions necessary for successful implementation of reforms, has not been successful in the implementation due to the unsound socio‐political milieu prevailing in the country.

This paper addresses only one aspect, i.e. the importance of a proper institutional framework. It emphasizes the need for further case studies to investigate the importance of other preconditions in developing countries.

The paper shows that the current analysis could be of immense value to the policy makers of both Sri Lanka and countries in South Asia.

The findings in this paper suggest that careful consideration of the country‐specific socio‐political conditions in developing countries should be taken, and reform measures devised accordingly.
