This current research aims to reveal customers’ behaviours who purchased à la carte menu service in a chain hotel operating in Istanbul, Türkiye after the Covid-19 outbreak. In addition to this main objective, customers’ main course preferences, tipping, complaining, maintaining eating and drinking habits, local food preferences, photograph taking and food waste behaviours were determined as the sub-research objectives.

Qualitative research method was adopted, and naturalistic observation was chosen as the data collection tool in this study. Firstly, an observation form was created based on the literature. To ensure the content validity, seven experts (five researchers and two experienced hotel employees) were consulted on 15 July 2021. After revising the form, a pilot study was carried out between 4 August and 29 September 2021. By conducting the pilot study, it was aimed to prevent any unpredictable behaviours of customers. As a result, four new items were added to, and two items were removed from the form. Then, 341 customers who purchased à la carte menu service in the restaurant of the hotel chain were observed between 7 October 2021 and 28 January 2022.

It was revealed that 52% of the customers who purchased à la carte menu services did not make any reservations, while approximately 59% of the customers with reservations did not stay at the hotel in which the research was conducted. In addition, 69% of them started to eat meal together; 56% of them paid in “cash”; 48% of them preferred local food and beverages; 41% left food on the plate; and 43% of them gave tip. In contrast, very few customers (6%) engaged in complaint behaviour.

First, data were collected during the post-pandemic period when international travels were mostly restricted and thus, the researcher observed mostly Turkish customers at the restaurant. Second, only those customers sitting at the six tables close to the guest welcoming were observed. Third, just one observer took part in the data collection process. Fourth, the researchers chose one out of two restaurants of the hotel because only Asian cuisine was served and children under 12 years of age were not allowed to enter the other restaurant. Fifth, focusing on only a hotel and using naturalistic observation as a data collection tool may be shown among the limitations of this study.

This paper presents the customers’ behaviours who preferred à la carte menu service in a chain hotel operating in İstanbul, Türkiye after the Covid-19 outbreak. Although there are some studies focusing on changing of customer preferences during the post-pandemic period, “observation” was not preferred as a data collection tool by most of the researchers; hence, the findings of this study are useful for both researchers and educationists in tourism industry.

This study investigates human behavior, specifically attitude and anxiety, toward humanoid service robots in a hotel business environment.

The researcher adopted direct observations and interviews to complete the study. Visitors of Henn-na Hotel were observed and their spatial distance from the robots, along with verbal and non-verbal behavior, was recorded. The researcher then invited the observed hotel guests to participate in a short interview.

Most visitors showed a positive attitude towards the robot. More than half of the visitors offered compliments when they first saw the robot receptionists although they hesitated and maintained a distance from them. Hotel guests were also disappointed with the low human–robot interaction (HRI). As the role of robots in hotels currently remains at the presentation level, a comprehensive assessment of their interactive ability is lacking.

This study contributes to the HRI theory by confirming that people may treat robots as human strangers when they first see them. When a robot's face is more realistic, people expect it to behave like an actual human being. However, as the sample size of this study was small and all visitors were Asian, the researcher cannot generalize the results to the wider population.

Current robot receptionist has limited interaction ability. Hotel practitioners could learn about hotel guests' behavior and expectation towards android robots to enhance satisfaction and reduce disappointment.

Prior robot research has used questionnaires to investigate perceptions and usage intention, but this study collected on-site data and directly observed people's attitude toward robot staff in an actual business environment.

Non-profit organizations (NPOs) are exposed to a highly competitive environment in which they are forced to grow their commercial activity to acquire additional financial resources. This study aims to create an understanding of how NPOs involved in textile reuse as a revenue-generating programme manage their reverse supply chains (RSC).

The research involves an embedded single-case study of NPOs in Finland involved in post-use textile collection. The main data sources are semi-structured interviews and participant observations.

This study is inspired by the microfoundations movement and identifies the underlying microfoundations of the NPOs’ capabilities for managing RSC for textile reuse. The study contributes to the literature by demonstrating NPOs’ lower-level, granular practices and their adaptations for achieving quality outcomes in textile reuse.

The findings have context sensitivity and apply to the NPOs which operate in a context similar to Finland, such as in other Nordic countries.

This study continues the discussion on the adoption of “business-like” practices in the NPOs’ pursuit of additional revenue streams to finance humanitarian work. The findings of this study can also be transferred to the growing area of domestic textile circularity.

Using the case of NPOs in textile reuse, the study illustrates how RSC management can serve a social, non-profit cause and transform unwanted textile products into a source of fundraising for humanitarian work.

This enriches the understanding of NPOs’ practices within the scope of revenue-generating programmes by examining one of them – textile reuse through charity shops from an RSC perspective.

Activity sampling is a technique to monitor onsite labourers' time utilisation, which can provide helpful information for the management level to implement suitable labour productivity improvement strategies continuously. However, there needs to be a review paper that compiles research on activity sampling studies to give readers a thorough grasp of the research trend. Hence, this paper aims to investigate the activity sampling techniques applied in earlier research from the angles of activity categories formation, data collection methods and data analysis.

The method used in this paper is a systematic review guided by the PRISMA framework. The search was conducted in Scopus and Web of Science. The inclusion and exclusion criteria were applied, selecting 70 articles published between 2011 and 2022 for data extraction and analysis. The analysis method involved a qualitative synthesis of the findings from the selected articles.

Activity sampling is broadly divided into four stages: targeting trade, determining activity categories, data collection and data analysis. This paper divides the activity categories into three levels and classifies the data collection methods into manual observation, sensor-based activity sampling and computer vision-based activity sampling. The previous studies applied activity sampling for two construction management purposes: labour productivity monitoring and ergonomic safety monitoring. This paper also further discusses the scientific research gaps and future research directions.

This review paper contributes to the body of knowledge in construction management by thoroughly understanding current state-of-the-art activity sampling techniques and research gaps.

The main purpose of this study was to explore how engaging in lesson study enhances secondary school mathematics teachers’ pedagogical practice in lesson planning in Jimma, Ethiopia.

The study employed a design-based research approach with qualitative and quantitative data collected from two secondary schools, and 12 mathematics teachers. A purposive sampling technique was used to select participants. Interviews, observations, questionnaires and document analysis were the main sources of data. Qualitative data were analyzed using themes with the support of Atlas-ti qualitative data analysis software. Quantitative data were analyzed using the Wilcoxon ranked signs test.

The findings revealed that engaging secondary school mathematics teachers in lesson study enhanced their lesson planning competence. As a result, teachers began to carefully plan detailed lessons, use curriculum materials and create more student-oriented lessons. Lesson study was found to be a potent model on which to build secondary school mathematics teachers’ lesson planning competence. Hence, it would be rewarding to integrate lesson study into the present school-based teachers’ pedagogical capacity-building program in the study settings.

The data were collected from particular localities with a small sample size in the quantitative phase. Therefore, it is difficult to generalize to the entire secondary school teachers in the country. However, thick descriptions were provided that would allow readers to determine the transferability of the findings to their specific school context. Future research should investigate the effects that enhanced TPP in lesson planning has on teachers’ mathematics teaching in more schools using a larger sample size.

This study provides insight into and empirical evidence of how engaging in the process of LS is essential to enhance teachers’ lesson planning competence. It adds important knowledge to a small but growing model of lesson study research. It also informs future researchers in the practical use of LS where lesson planning is a crucial concern in many secondary schools of the country.

This research was originally conducted to build mathematics teachers' pedagogical practice in lesson planning through lesson study in Ethiopian secondary school contexts.

We take Cumulative Prospect Theory (CPT) seriously by rigorously estimating structural models using the full set of CPT parameters. Much of the literature only estimates a subset of CPT parameters, or more simply assumes CPT parameter values from prior studies. Our data are from laboratory experiments with undergraduate students and MBA students facing substantial real incentives and losses. We also estimate structural models from Expected Utility Theory (EUT), Dual Theory (DT), Rank-Dependent Utility (RDU), and Disappointment Aversion (DA) for comparison. Our major finding is that a majority of individuals in our sample locally asset integrate. That is, they see a loss frame for what it is, a frame, and behave as if they evaluate the net payment rather than the gross loss when one is presented to them. This finding is devastating to the direct application of CPT to these data for those subjects. Support for CPT is greater when losses are covered out of an earned endowment rather than house money, but RDU is still the best single characterization of individual and pooled choices. Defenders of the CPT model claim, correctly, that the CPT model exists “because the data says it should.” In other words, the CPT model was borne from a wide range of stylized facts culled from parts of the cognitive psychology literature. If one is to take the CPT model seriously and rigorously then it needs to do a much better job of explaining the data than we see here.

To address the absence of Lean in transportation logistics in the digital era, this study aims to investigate the application of Lean transportation (LT) tools to reduce waste and facilitate the digital transformation of dedicated road transportation in the offshore industry.

The study adopts action research with a multimethod approach, including a scoping review, focus groups (FG) and participant observation. The research is conducted within the offshore supply chain of a major oil and gas company.

Implementing LT’s continuous improvement tools, particularly value stream mapping (VSM), reduces offshore transportation waste and provides empirical evidence about the intersection of Lean and digital technologies. Applying techniques drawn from organisational learning theory (OLT), stakeholders involved in VSM mapping and FGs engage in problem-solving and develop action plans, driving digital transformation. Waste reduction in loading and unloading stages leads to control actions, automation and process improvements, significantly reducing downtime. This results in an annual monetary gain of US$1.3m. The study also identifies waste related to human effort and underutilised digital resources.

This study contributes to theory and practice by using action research and LT techniques in a real intervention case. From the lens of OLT, it highlights the potential of LT tools for digital transformation and demonstrates the convergence of waste reduction through Lean and Industry 4.0 technologies in the offshore supply chain. Practical outputs, including a benchmarking questionnaire and a plan-do-check-act cycle, are provided for other companies in the same industry segment.

This paper explores how risks are managed in project practice beyond formalized risk management processes by applying the lens of actuality research to project risk management.

The paper follows a qualitative multimethod research approach utilizing literature review, interviews, observations and document analysis. The paper is based on three case studies and one interview study in project organizations facing green transition challenges.

Little work exists to reveal how risk management is actually done by project practitioners, and why. Few studies report on contextual variation and consider confounding factors beyond a “one size fits all” formalized explicit risk management process, despite ample evidence that risks are managed outside the formal process. The study documents that informal and/or implicit risk management activities add significantly more value.

The paper contributes a literature review of research into the actuality of project risk management, a sense-making framework of how risks are managed in practice beyond the formal, explicit risk-management process by including informal and/or implicit risk management activities, an empirical study of risk-management practice highlighting that informal and/or implicit risk-management activities dominate in practice, a discussion of why risks are managed outside formalized, explicit process and a research agenda to enable the design of impactful project risk-management practices.

The study explores the possibility of developing a valid scale for integrated management of heritage sites to bring a holistic approach to heritage properties' conservation practices.

The study followed the exploratory sequential method. An in-depth interview was adopted for exploring indicators, and a questionnaire survey was administered for descriptive analysis.

Cultural resources conservation strategies have been analyzed from a tourist, local communities and stakeholder's perspective with local-specific indicators. The study indicates that a multi-dimensional approach that integrates tourists, local communities and other stakeholders-based indicators can be developed at the destination level for the integrated management of heritage properties. Tourist-centric, local community-specific and stakeholder-oriented approaches could act as catalysts for more pragmatic conservation practices in the local areas based on the site-specific indicators.

The study is limited to lesser-known heritage sites located in the southern provincial states of India. The technical conservation strategies on the structure and architecture are not part of the study. Theoretical implications on the study of this kind can contribute to the literature as it throws light on future studies seeking local-centric conservation and management practices of heritage sites hitherto less explored in the domain of conservation science. The scale provides insight into the appropriate form of intervention that the local communities, tourists and other stakeholders can do at the heritage sites, hence the possibility of garnering the attention of other discipline strivings towards the conservation of heritage sites and to apply along with other relevant variables. It is expected that the study might expedite the knowledge accumulation in conservation science.

The scale can be used in a similar context for the integrated management of heritage sites. The study can assist the policymakers and planners in seeking the support of stakeholders, local communities and tourists for the implementation of heritage conservation and management programs. Such a local-centric management strategy promoting responsible consumption and production could contribute to SDG 12. Further, the study can also contribute towards SDG 11.4, which calls for strengthening the effort to protect and safeguard cultural and natural heritage. This scale can be a tool for destination management organizations (DMOs) to understand the level of intervention of local communities, tourists and other stakeholders at the heritage site.

The integrated management approach of heritage conservation immensely helps the lesser-known heritage sites the world over as such structures are out of the focal point of government funding and other conservation efforts. The synergy of the integrated approach could protect lesser-known unfunded heritage sites, and thereby, the cultural reflections of the community concerned can be made available for future visitors’ consumption.

The study attempted to understand the conservation approaches for lesser-known heritage sites with the support of both demand and supply-side stakeholders. Such a collaborative approach is the first of this kind in the conservation of heritage sites in India.

This study aims to focus on public policy concerning the implementation of public procurement policies in Nigeria and Ghana toward achieving value for money in the procurement of goods, services and works. It specifically analyzes some major administrative challenges Nigeria and Ghana are faced with in the administration/implementation of public procurement policies toward achieving value for money. It looks at the relationship between the state (regulatory authorities) and substate (procurement entities) in the public sectors of Nigeria and Ghana.

A comparative case study approach is adopted, where the two countries are compared in terms of achieving value for money. Data was collected from multiple sources, including in-depth interviews. The use of official documents and direct observations at the procurement regulatory authorities and entities’ premises.

This study found Nigeria often used the four Es – economy, efficiency, effectiveness and equity while Ghana mainly used the traditional five rights (right quantity, right quality, right price, right place and right time) as their criteria for ensuring value for money. The major administrative challenges found include corruption, low capacity of procurement personnel and poor knowledge of the procurement laws.

It recommends effective collaboration between government and civil society groups in the fight against corruption in procurement-related activities, with the implication that there is a need for periodic training for public procurement officials.

It adds to the field of public procurement in terms of value for money in the procurement of goods, services and works in developing countries context.
