While the effect of the minimum wage (MW) on employment has been widely studied, less is known about its impact on hirings and separations. Whereas the adverse effects of MW on hiring are quite familiar, results of studies indicating reductions in separations are less expected. This study aims to bridge the gap between theory and practice by performing a meta-analysis, which allows for understanding the real effect of MW on employment's two components: hirings and separations.

Since mixed results cloud understanding of the issue, a meta-regression analysis was conducted. This technique permits understanding the effect of MW on labor market transitions and offers additional explanations for controversial results.

Despite the evidence that MW increasing the turnover and reducing permanence could negatively affect employment, findings from meta-regression analysis pointed out that increases in MW reduce hirings but also separations offsetting the negative effect on employment. Overall, the results imply that the standard finding that MW changes have little or no impact on employment rates reflects offsetting reductions in hiring and separations. Evidence of negative publication bias is also found.

The results emphasize the importance of looking beyond employment rates to understand the impacts of MW. Overall, the evidence implies that the standard finding that MW changes have little or no impact on employment rates reflects offsetting reductions in hiring and layoffs. In addition, the results suggest that MW tends to have a much larger impact on employment flows than on employment levels. This finding has to be considered by policymakers when they make decisions about increasing the MW. These analyses assist in clarifying debates about the effects of MW on the labor market in the changing economic environment and conduct a labor policy in the right direction.

The meta-regression analysis (MRA) conducted in this study emphasizes the importance of looking beyond employment rates to understand the impacts of MW (Brochu and Green, 2013). Overall, the evidence implies that the standard finding that MW changes have little or no impact on employment rates reflects offsetting reductions in hiring and layoffs. Therefore, the evidence from the performed MRA is consistent with those previous meta-analysis studies that found little or no evidence about MW adversely affecting employment and, at the same time, provide additional explanation for these findings. In addition, the results suggest that MW tends to have a much larger impact on employment flows than on employment levels (Dube et al., 2016).

Even though hirings are reduced due to MW, this evidence could not necessarily imply a negative effect of MW on the labor market since job searching or matching is improved. Additionally, the increases in MW could improve the quality of the job and the job attachment, which are consistent with a recruitment-retention model (Dube et al., 2007). The evidence from this MRA, which is consistent with little or no impact of MW on employment, also could imply that although the MW is set relatively high to balance the supply and demand of labor, their level is close to optimal. Setting the right level is also associated with compliance with MW. This issue deserves attention since any adverse employment effects of MW could be strengthened by incomplete coverage. The effectiveness of the entire process of developing, putting into practice and enforcing MW rules hinges on compliance.

As prior meta-regression analysis did not have the same objective, the results of this article move current research forward. Based on the analysis, future research lines are delineated, and some public policy implications are assessed.

The purpose of this paper is to assess the waste characteristics and separation efficiency of source separation of household waste in low- and middle-income communities in Kumasi Metropolis, Ghana.

A sample of 60 households participated in the household survey, education on source separation and pilot source separation exercise. The solid waste was sorted into six fractions and three recycling categories (biodegradable; paper and plastic; residue).

The mean generation rate of solid waste was 0.52±0.26 kg/per capita/day for the low-income community and 0.65±0.27 kg/per capita/day for the middle-income community. The waste fractions in the communities (low, middle income) were biodegradable organics (59.15, 65.68 per cent), plastics (11.01, 10.68 per cent), papers (3.15, 4.51 per cent), glass (0.89, 2.57 per cent), metals (0.96, 4.63 per cent) and miscellaneous (24.84, 11.93 per cent), respectively. The separation efficiency for organic category was 70 per cent, inorganic and residue was over 69 per cent and the paper and plastics was over 60 per cent.

The study suggests that the success of source separation programme hinges on education and economic incentives. It was noted that the sample size could be increased to enhance the accuracy of the data for prediction purpose.

The findings showed there is potential for recycling through source separation programme in low-and middle-income communities. Public education and economic incentives are necessary for successful source separation programme.

The paper provides insight into source separation to contribute to better understanding of how city authorities in developing countries could take advantage of economic incentives to scale-up recycling.

Service separation distress arises when service consumers worry that a useful service may become unavailable. This paper aims to integrate two theoretical explanations of ongoing service use, being service continuance and relationship commitment and a common foundation of cognitive social capital.

This study conducts an online survey of 245 cloud service consumers, which we use to test our research model.

This paper finds that relationship commitment mediates the service continuance explanation in explaining service separation distress.

While service features are important, they are less important than the consumer’s perceived relationship with the service in promoting perceived service separation distress. Contrary to expectations, the finding identified the service relationship as the dominant explanation for service separation distress.

Jeopardy to the consumer-provider relationship can create greater anxiety and distress to consumers than a disruption that threatens service features alone. Adding service features may not reduce customer separation distress regarding the service.

The unified cognitive social capital lens on service separation suggests that consumers value service provider relationships (e.g. commitment and trust) over service features. A stronger social relationship with the consumer, in turn, strengthens the perceived service offering.

This is among the first studies to unify two explanations of service continuance using social capital and to empirically identify how this explanation affects service distress.

This study aims to accurately simulate the tilting separation process of mask projection stereolithography (MPSL) and verify the tilting theory.

The finite element separation models of MPSL 3D printing process were established. The established models simulated both tilting and pulling-up separation process by changing the constraints and boundary conditions. The bilinear cohesive curves were used to define the separation interface. The stress distribution of the cured part and FEP film at different times during the whole separation process was extracted. Different orientations of pulling-up and tilting were also compared for stress distribution. The stress change was analyzed for the center and edge points of the upper surface of cured part.

The results showed that the stress increased with the separation speed, and the stress at the edge position of exposure area was greater than the internal position. The tilting traction stress distribution was affected by the exposure area function and the velocity distribution. Alternation of the exposure area function changed the cohesive stiffness. The non-coincidence of the calculated traction stress with the input bilinear cohesive curve reflected the influence of the material properties and the separation methods. The high-speed side of tilting had fast separation and high traction stress.

This study proposes a technical method for simulation tilting separation and verified the tilting theory. The cohesive zone model was proved applicable to the tilting traction stress calculation.

This paper positions environmental concern as the antecedent of attitude, subjective norm and perceived behavioural control. It also sets to expand the theory of planned behaviour by including two condition factors: favourable situation and facility availability on the intention to separate food waste at source.

The study collects data by using self-administered questionnaires on 682 respondents in Malaysia. Structural equation modelling is employed to test the conceptual model and the proposed hypotheses.

The results show that environmental concern positively influences attitude and subjective norms, which, in turn, influences food waste separation intention. Favourable situation and facility availability are found to influence the separation intention.

This study is one of the earliest studies to investigate residents’ intention to participate in food waste separation at a source that employs the expanded theory of planned behaviour with environmental concern and condition factors.

Excessive liquid carryover in T-junction presents a serious operational issue in offshore production platform. Slug flow and diameter ratio of T-junction are considered as two major factors causing liquid carryover. Regular and reduced T-junction are being used as partial phase separator but their efficiency is low. Converging T-junction with two distinct diameters (primary and secondary) in branch arm is used to improve the phase separation efficiency. The motivation is to combine specific feature of regular and reduced T-junction to increase separation efficiency of existing T-junction without involving too much operational workover. The purpose of this paper is to numerically evaluate the separation efficiency of a converging T-junction design. The present model and its methodology was validated with in-house experimental data for 3 inches diameter flow loop.

The slug flow regime was simulated using incompressible Eulerian mixture model coupled with volume of fluid method to capture the dynamic gas-liquid interface.

The analyses concluded that T-junction with primary-secondary branch arm diameters combination of 1.0-0.5 and 0.67-0.40 managed to achieve 95 per cent separation efficiency. The research also confirmed that over reduction of T-junction secondary diameter ratio below 0.2 will lead to decrease in separation efficiency.

The present research is limit to air/water two-phase flow but the general results should be applicable for wider application.

The proposed design limited excessive workover and installation for current and existing T-junction. Hence, cutting down installation cost while improving the separation efficiency.

The present research resulted in higher separation efficiency, cutting down production down time and lead to operational cost saving.

The present research proposes an original and new T-junction design that can increase phase separation efficiency to over 90 per cent. The finding also confirmed that there is a limitation whereby smaller diameter ratio T-junction does not always resulted in better separation.

One of the major concerns of the constrained-surface stereolithography (SLA) process is that the built-up part may break because of the force resulting from the pulling-up process. This resultant force may become significant if the interface mechanism between the two contact surfaces (i.e. newly cured layer and the bottom of the resin vat) produces a strong bonding between them. The purpose of this paper is to characterize the separation process between the cured part and the resin vat by adopting an appropriate and simple mechanics-based model that can be used to probe the pulling-up process.

In this paper, the time-histories of the pulling-up forces are measured using FlexiForce® force sensors. The experimental data are analyzed and used to estimate the constitutive parameters of the separation mechanism. Here, the separation mechanism is modeled based on the concept of cohesive zone model (CZM) that is well-studied in the field of fracture mechanics. By using the experimentally measured pulling-up force, this paper proposes a very efficient inverse technique to estimate the constitutive parameters for the CZM. The constitutive laws for the CZM facilitate in relating the separation force at the interface between the cured part and the resin vat in terms of the pulling-up velocity. Unlike work proposed earlier, computationally expensive full-scale finite element runs are not essential in the current work while estimating the required parameters of the constitutive laws. Instead, mechanics-based computationally efficient surrogate model is proposed to readily estimate these constitutive parameters.

Two constitutive laws are compared on the basis of their predictions of the separation force profile. Excellent match is obtained between the measured and the predicted separation force profiles.

This paper selects a suitable mechanics-based model that can characterize the separation process and proposes a computationally efficient scheme to estimate the required constitutive parameters. The proposed scheme can be used to reliably predict the separation force for the constrained-surface SLA process, leading to improved productivity and reliability of the SLA processes in fabricating the built-up parts.

Service encounters are becoming increasingly virtual through the infusion of computer-mediated technologies. Virtual services separate consumers and service providers both spatially and temporally. With the advent of virtual services is the need to theoretically explain how service separability is psychologically perceived by consumers across the spectrum of computer-mediated technologies. Drawing on construal-level theory, the purpose of this paper is to conceptualize a theoretical framework depicting consumer’s construal of spatial and temporal separation across a continuum of technology-mediated service virtuality.

The authors conducted two studies: first, to investigate consumers’ levels of mental construal associated with varying degrees of service separation across a spectrum of technology-mediated services; second, to empirically examine consumer evaluations of service quality in response to varying degrees of spatial and temporal service separation. These relationships were tested across two service industries: education and tourism.

Consumers mentally construe psychological distance in response to service separation and these observations vary across the spectrum of service offerings ranging from face-to-face (no psychological distance) through to virtual (spatially and temporally separated – high psychological distance) services. Further, spatial separation negatively affects consumers’ service evaluations; such that as service separation increases, consumers’ service evaluations decrease. No such significant findings support the similar effect of temporal separation on customer service evaluations. Moreover, specific service industry-based distances exist such that consumers responded differentially for a credence (education) vs an experiential (tourism) service.

Recent studies in services marketing have challenged the inseparability assumption inherent for services. This paper builds on this knowledge and is the first to integrate literature on construal-level theory, service separability, and virtual services into a holistic conceptual framework which explains variance in consumer evaluations of separated service encounters. This is important due to the increasingly virtual nature of service provider-customer interactions across a diverse range of service industries (i.e. banking and finance, tourism, education, and health care). Service providers must be cognisant of the psychological barriers which are imposed by increased technology infusion in virtual services.

The purpose of this paper is to examine the impact of service separation on the ability of service firms to build and maintain customer relationships, by exploring the differences in the strength of interrelationships among key relational constructs between separated and unseparated service delivery modes.

A field survey was conducted with retail banking customers in Saudi Arabia (n=592) using a structured self-administered questionnaire consisting of well-established scales. Data were analyzed using AMOS 24.

Service separation negatively moderates (weakens) the ability of the service firms to leverage their social benefits, relational trust and affective commitment to increase customer loyalty and to strengthen overall customer relationships.

This study uses retail banking customers in Saudi Arabia to test the impact of service separation in their relationship with the bank; hence, its findings may not be generalizable to other types of services and cultural settings.

Service firms using online and mobile technologies should be aware that trust and commitment remain key to building customer loyalty. Hence, the trade-off between the benefits of these technologies and their negative impact on customer relationship needs to be factored into managerial decision making.

The paper highlights the importance of maintaining face-to-face interactions with service customers to create robust relationships that yield loyalty, despite the growing popularity of online and mobile technologies.

The majority of medium‐to‐large international organizations have adopted enterprise resource planning systems (ERPs) of which SAP R/3 is the current market leader. This paper proposes a framework for the separation of duties in SAP R/3. Separation of duties is viewed as a critical component of an organization’s internal control structure aimed primarily at reducing opportunities for fraudulent activities. R/3 assigns profiles consisting of authorizations to users. Accordingly, R/3 facilitates the implementation of “role‐based access control”, where these profiles may be designed consistent with organizational roles and assigned to users performing these roles. This paper proposes a framework for adequate separation of duties using a role‐based approach in the financial accounting (FI) module of the R/3 system. Case studies were undertaken to refine the framework and to explore its application in a practical environment. This empirical research provided support for the adequacy of the proposed framework.
