The construction industry today is one of the biggest industries in the world. As projects continue to grow in complexity, project management continues to evolve. Contractor selection is a difficult task that owners and project managers face. Although previously researchers have worked on the subject of contractor selection, a comprehensive decision support system for contractor selection has not yet been developed. Recent reports of major delays and cost overruns in mega projects highlight the need for a model that is able to be flexible and comprehensive becomes evident. The paper aims to discuss these issues.

The research focuses on obtaining insights from field experts using both quantitative and qualitative methods. Then, a model was developed in the light of the data collected. Accordingly, the model was tested on a case study.

This paper presents a model for contractor selection that is wholesome in its take on the topic. The model incorporates both managerial and technical aspects of the problem. The model was tested on a case study and it was proven to be feasible in real world applications. The contractor selection decision support system serves the needs of both academics and industry managers, as an integral part of project management.

The model presented in this paper is innovative in its take on the problems. MCDA tools have been uniquely modified in this paper to cater to the needs of the selection problem while accounting for the criteria hierarchy that incorporates aspects that are instrumental for proper evaluation of a contractor’s likelihood of success.

Building a bioeconomy requires efficient technology transfer and global linkages to exploit finite intellectual property exclusivity periods. The purpose of this paper, using a resource‐based view lens, is to assess the priorities, capabilities, and competitiveness of the emerging New Zealand (NZ) bioeconomy.

A triangulated design was used that involved four focus groups, 27 interviews, five case studies, and survey of 176 NZ biotechnology industry participants from a broad range of backgrounds such as scientists, managers, and investors.

Two high‐priority capabilities were identified as being critical to fostering a competitive bioeconomy – access to talent and access to funding. Participants also identified the critical role of government in building and coordinating infrastructure, enabling critical capabilities, and accelerating bi‐directional technology and capital flows.

Most biotechnology research and data has focused on the USA and European Union. This is one of the first studies of NZ biotechnology participants, and insights gained within this context are potentially applicable for increasing our understanding of building biotechnology industries outside established clusters.

Tom Gould, an entrepreneur, had been operating Treadwell’s Ice Cream, a small ice cream restaurant since 2000. Treadwell’s Ice Cream had been preparing its financial statements under cash basis. Tom Gould turned over all his receipts, both personal and business expenses, to his bookkeeper who entered them into QuickBooks. At tax time, his tax accountant excluded non-qualifying expenses from the tax filing. Periodically, Tom met with his bookkeeper to determine the results of operations and financial position at the end of that period of time. Most of Treadwell’s transactions were easily recognized by Tom, who preferred to pay all expenses by cash rather than credit. However, the bookkeeper had not been separating operating from non-operating activities, and had been using multiple accounts to record the same or similar costs. Therefore, the current income statement and balance sheet were not appropriately categorized and organized. In addition, since the bookkeeper was not a tax account, business expenses had been mixed with Tom Gould’s personal expenses on the income statement. There were no adjustment to the income statement after the tax accountant identified non-qualifying expenses when preparing tax filing. As Tom and his wife were considering turning over more day to day operations to his son and hiring a non-family member as a manager to help his son, he would need the books to provide an accurate picture of the business.

Primary source materials included interviews with the owner, Thomas Gould, his son, Michael Gould, and their Accountant, Tom Mallas. Secondary source materials included monthly and annual financial data from QuickBooks (monthly data are available upon request but are not relevant to the case discussion). Other secondary source materials included geographic, economic, industry, and competitors’ information.

This case is well suited for an introductory level undergraduate financial accounting course, after accrual accounting and accounting information systems (accounting cycles) have been introduced. When analyzing this case, students will apply concepts and principles of financial statement preparation. The case is also appropriate to serve as a review of accrual accounting, and of income statement and balance sheet preparation at the beginning of an intermediate level financial accounting course. Students can be asked to reformat the income statement from the single-step format to the multiple-step format. By working through financial statements with common errors found in small businesses, students can practice identifying these errors, thus providing a review of the various sections of the income statement and prepare students for more in-depth discussions of each section. In a tax course, this case can stimulate discussions on non-qualifying expenses and common shortcomings in small business accounting.

This case focusses on management and customer service issues at a historic hotel, the Hawthorne, in Salem, Massachusetts. By 1999, when Juli Lederhaus was hired as the new general manager, the Hawthorne had a reputation of being well past its prime and customers were dissatisfied with the quality of service and outdated physical facilities. This case describes the actions she took, up to 2012, to improve service. The case ends with Lederhaus contemplating whether more changes are needed given that she had just heard a rumor that a company was considering building a new hotel just a few blocks away. The case gives students the opportunity to analyze the strengths and weaknesses of the Hotel in relation to customer service, and propose recommendations for future improvements.

A qualitative, interview based, methodology was used. The researchers held numerous, face-to-face interviews with the owner and employees of various ranks. Information was also gathered from archival data and traveler review sites such as TripAdvisor.com and Yelp.com.

The case is targeted to undergraduate business and hospitality students at a sophomore or junior level. Classes in which this case could be used include: Organizational Behavior, Human Resource Management, and Hospitality Management.

The purpose of this paper is to examine affective events theory (AET) by testing the mediating effect of employees’ positive affect at work in the relationships of leaders’ use of positive humor with employees’ work engagement, job performance, and organizational citizenship behaviors (OCBs); and the moderating effect of transformational leadership style on the relationship between leaders’ use of positive humor and subordinate’s positive affect at work.

Data were obtained from 235 full-time employees working for a large information technology and business consulting corporation. Moderated mediation (Hayes, 2013) was performed to test the proposed model.

Leaders’ positive humor was related to creation of subordinates’ positive emotions at work and work engagement. Positive emotions at work did not mediate between leaders’ humor and performance or OCBs. In addition, leaders’ use of transformational leadership style made the relationship between leaders’ positive humor and employees’ positive emotions at work stronger.

This study provides evidence of the positive relationship of leaders’ positive humor with employees’ positive emotions at work and work engagement. Such knowledge may help to inform the training workshops in humor employed by practitioners and potentially create a more enjoyable and fun workplace, which can lead to greater employee engagement.

AET helps explain effects of leader humor, but the effects of are complex. Leader’s use of even positive humor is most likely to have favorable effects mainly depending on their leadership style (transformational) and if their humor successfully leads to positive emotions among employees.

This study investigates the viability and benefits of implementing underground waste management systems in Doha in response to the city’s increasing waste production. It examines the necessity, feasibility and public opinion of these systems, exploring perceived benefits and implementation barriers.

Adopting a convergent parallel design, the study separates quantitative and qualitative data for thorough analysis. Non-probability random sampling based on Slovin’s formula targeted 385 participants, with 100 responses and five in-depth interviews obtained. Data were analysed using SPSS and NVivo, ensuring validity and reliability through Cronbach’s alpha and instrument pretesting.

The study reveals varied perceptions among Doha residents towards municipal and zero waste initiatives, highlighting a significant gap in waste segregation practices at home and low awareness of waste disposal processes. Underground systems face significant barriers, including financial constraints and limited knowledge about advanced technologies like Lusail City’s compressed air system. The findings indicate strong public support for enhancing waste management systems and emphasize the need for better public education and strategic infrastructure investments.

This research offers key insights for decision-makers, improving understanding of waste management strategies in Doha. It connects theory with practice to promote sustainable and effective waste management solutions while exploring public perceptions and challenges of implementing underground systems.

As public–private partnerships (PPPs) have become preferred and veritable approach to deliver affordable housing, the seemingly lack of understanding of the significant factors that impact on success has become a notable setback. This study aims to delineate significant factors that can support decisions in affordable PPP public housing delivery.

Largely, a questionnaire survey was adopted to elicit insights from practitioners, policymakers and experts to develop an evaluative decision support model using an analytical hierarchy process and multi-attribute utility technique approach. Further, an expert illustration was conducted to evaluate and validate the results on the housing typologies.

The results revealed that energy efficiency and low-cost green building materials scored the highest weighting of all the criteria. Furthermore, multi-storey self-contained flats were found to be the most preferred housing typology and were significantly influenced by these factors. From the model evaluation, the scores on the factors of sustainability, affordability, cultural values and accountability were consistent across all typologies of housing whereas that of benchmarking, governance and transparency were varied.

The decision support factors captured varied dimensions of key factors that impact on affordable PPP housing that have not been considered in an integrated manner. These findings offer objective and systematic support to decision-making in affordable PPP housing delivery.

During the refugee resettlement process, women are often subject to discriminatory policies, which may put them at risk of a difficult transition. This study aims to extend and contextualize previous findings documenting the barriers Arabic-speaking refugee and immigrant women face with regards to gaining education and employment.

Through telephone-based surveys, the authors examined the social situations, barriers and assets to gaining education and employment among Arabic speaking refugee and immigrant women (N = 50) in North Carolina.

Findings include barriers to education and employment such as the need for childcare, English proficiency and lack of transportation. Assets include connections to the community and special skills such as cooking and sewing.

This study has limitations such as a lack of representation among asylees, reliance on self-report and small sample size. Implications: this study’s findings have implications for community and medical providers’ efforts to assist refugees and immigrant’s women in education and employment and to close the gap in the social determinants of health as well as for research in this area. Minimizing the barriers that prevent them from learning English or attaining employment will require coordinated efforts across the local community, county and even the state.

The findings from this study inform research that may be relevant to other communities seeking an understanding of the social challenges faced by Arabic-speaking refugees and immigrant women, Muslim and Christian.

This study adds important information about the health and social lives of an understudied population. The authors’ discuss the implications of these findings for community members and health practitioners to better assist this population in a successful resettlement process.

Consistent with traditional internationalization theory, we argue that, when a firm chooses franchising to achieve market penetration, market propinquity/similarity matters. Using a modified gravity model, we examine six country characteristics believed to enhance the flow of franchise activity among 39 nations. Our findings support the notion that market propinquity facilitates the flow of franchises between nations. Franchise expansion is greatest when the home and host nations are similar in terms of geography, culture, media availability, and political risk. The management implications of these findings are discussed in detail.
