In the field of mobile communications services (MCS), it is of importance to segment MCS users to support operators in better tailoring their offers to the needs of specific customer groups. This paper analyzes the suitability of national origin of MCS subscribers to segment residential customers into groups with significantly diverging usage behaviors in a sample living in one of the Gulf Cooperation Council (GCC) member states with a large share of expatriates in its population, particularly from South Asian countries. If MCS use patterns vary considerably between nationals, South Asian migrants and other foreign nationalities, it makes much sense to segment customers at least into these three groups.

The investigation applies discriminant and regression analysis on a sample of 4,892 residential postpaid MCS customers in a GCC country. The sample comprises individual usage data of 2,446 national citizens and an equal number of non-nationals between July 2014 and July 2015, living in the focal country. The data set was extracted from the billing and customer management systems of a collaborating mobile network operator (MNO).

The results imply that national origin is a highly significant predictor of individual MCS usage. Nationals and all expatriates primarily differ in international voice and SMS usage but not in established national MCS and mobile internet use intensity. Among expatriates, South Asians consume more national and international voice minutes than migrants originating from other foreign nations.

The analysis is based on objective MCS usage data retrieved from an MNO’s data warehouse. It lacks information on customer perceptions of the utility of various MNO service categories and on other individual characteristics, such as the customers’ level of education or language proficiency. To overcome this limitation, empirical research is needed that incorporates additional objective customer descriptors as well as subjective perceptual constructs.

MNOs are well advised to develop service bundles and tariff portfolios specifically designed for nationals and for different groups of expatriates.

The paper extends the literature on MCS usage behavior in Arab states in general and on customer MCS usage segmentation based on individuals’ national citizenship in particular.

Providers of cloud computing storage services (CCSS) charge offers in several unit bundles for a lump sum per bundle. This non-linear pricing approach is known as a bucket-pricing plan (BPP). If a customer exploits the purchased bucket, he/she can opt for the next higher bucket or refrain from further CCSS use. CCSS suppliers are faced with an optimization problem concerning the number of buckets as well as their lower and upper storage volume boundaries. The purpose of this paper is to develop a model, which supports CCSS suppliers in deriving a BPP-structure and which maximizes their profit in varying market constellations.

The authors develop a multi-period model of tariff choice decisions of private customers of CCSS. The model is applied in Monte Carlo simulations to determine profit-maximal tariff structures as a function of different market characteristics such as median demand saturation, demand heterogeneity, average price per storage unit and bucket ceiling allocation (identical size of each bucket within the frame set by the lower and upper overall boundary, varying sizes of the buckets offered, so that the interval between two ceilings consecutively increases for subsequent buckets) and type of a customer’s utility function.

The simulation analysis suggests that demand heterogeneity and average price per unit are the most influential factors for CCSS tariff structure optimization. Price plans with more than two buckets tend to generate higher profits than simple schemes with two buckets only if demand heterogeneity is low and the average price per storage unit is high and/or median saturation level of customers is low.

Despite the popularity of BPP among providers of CCSS for consumers, there is a lack of scholarly modeling work on the profit implications of the number of buckets entailed in a scheme and the size/ceilings of the various buckets on offer. The model suggested in this paper is a first step toward narrowing this research gap.

Artificial intelligence (AI) has gained significant momentum in recent years. Among AI-infused systems, one prominent application is context-aware systems. Although the fusion of AI and context awareness has given birth to personalized and timely AI-powered context-aware systems, several challenges still remain. Given the “black box” nature of AI, the authors propose that human–AI collaboration is essential for AI-powered context-aware services to eliminate uncertainty and evolve. To this end, this study aims to advance a research agenda for facilitators and outcomes of human–AI collaboration in AI-powered context-aware services.

Synthesizing the extant literature on AI and context awareness, the authors advance a theoretical framework that not only differentiates among the three phases of AI-powered context-aware services (i.e. context acquisition, context interpretation and context application) but also outlines plausible research directions for each stage.

The authors delve into the role of human–AI collaboration and derive future research questions from two directions, namely, the effects of AI-powered context-aware services design on human–AI collaboration and the impact of human–AI collaboration.

This study contributes to the extant literature by identifying knowledge gaps in human–AI collaboration for AI-powered context-aware services and putting forth research directions accordingly. In turn, their proposed framework yields actionable guidance for AI-powered context-aware service designers and practitioners.

Findings from a comparative qualitative study with parents in the USA and China increase the understanding of experiences of adults with autism in both countries.

Semi-Structured interviews were conducted with families in the USA and in China. In total, 18 families participated in the study – 7 in the USA, 11 in China.

Analysis of the comparative data led to the emergence of three overarching themes, expressing both similarities and differences in experiences: 1) transition to adult services plays out differently in the two nations, 2) parent advocacy and efforts in supporting and securing services for their children are strong in both countries but are also defined by the variability in access to services and 3) due to the scarcity of adult services in their country, Chinese parents express significantly more worries about their own aging and mortality as compared with USA parents.

Practical implications and directions for future research are discussed.

By examining the experiences of families of adults with autism in the USA and China, the research reveals themes that would not be visible in a single-nation study.

Purpose: This chapter examines alternative education programs available for Myanmarese migrant youth in Thailand, what these young migrants expect of education, and how these migrant learning centers (MLCs) can help provide more opportunities for migrants.

Methods: This study draws from the data collected through two stages of qualitative research undertaken in Mae Sot, a town that borders Myawaddy, Myanmar in Thailand. Stage one consisted of ethnographic research with the local Myanmarese diaspora when I worked as a volunteer at a community-based organization. In stage two, a series of interviews were conducted with eight faculty members and twenty students enrolled in the secondary school level or vocational training program of three local MLCs.

Findings: The main finding is that even with both inclusive education policies and alternative education options in place, there is still a missing link between the educational attainment of Myanmarese migrant youth and their future prospects. While Thai public education seems to be a pathway to more future opportunities in the host country, it can be a trap when migrant youth cannot make good use of their learned knowledge and Thai language skills in the future due to their irregular status. In contrast with Thai public schools, MLCs offer more than simply education. They also provide scholarship, employment and social welfare assistance to serve the varying needs of young migrants.

Originality: The case of Myanmarese migrants presents a unique study in which the gap between students’ educational attainment and future prospects cannot necessarily be bridged even with a valid work visa scheme in place. Some Myanmarese migrants are displaced individuals who fled from civil wars and without any identification documents. The legal systems enforced by nation-states, such as Thailand, that rely on identification documents to control the flow of population still lack the capacity to adequately address the educational needs and employment opportunities of individuals with irregular status.

This paper aims to present a state-of-the-art review of building information modelling (BIM) in the UK construction practice. In particular, the aim is to examine the scope, value and practical implications of BIM implementation in residential projects by evaluating practitioners’ perspectives working in the Greater London Area (GLA).

The paper outlines the general status quo of BIM adoption and maturity in the UK. It then discusses the feasibility of BIM use in residential projects drawing on an online survey and complementary semi-structured interviews with building professionals. The cross-comparison between the evidence base and literature review uncovers the specific benefits, challenges and risks to BIM implementation in the house building sector.

BIM is an evaluation methodology that helps the management of digital information throughout the project lifecycle. At a conceptual level, a BIM-enabled project offers quality assurance and on-time delivery, collaboration and communication improvement, visual representation and clash detection and whole lifecycle value. The findings, however, suggest that the most frequently reported benefits are related to collaboration and the blend of product (software) and process innovation, whilst lifecycle thinking and waste reduction are often overlooked. At present, there is widespread awareness on BIM but with a financial barrier to invest in developing digital capabilities, particularly for small- and medium-sized enterprises.

The paper concludes with a critical commentary on the lack of strategic leadership in both the supply and demand side. The role of policy to streamline commercial drivers for whole lifecycle costing in procurement is endorsed to drive the change management required to address the short-term mind-set of senior management and wider fragmentation of the construction industry, also serving as a research question for further research and development in the field.

There are relatively few studies evaluating BIM perspectives in UK residential projects. This paper explores the feasibility and “real-life” value of BIM in housing practice, drawing on views and experiences of building professionals in GLA. In particular, the research findings provide an evidence base evaluating the extent to which the house building industry has the expertise and capability to operate in a BIM environment and to comply with the Level 2 mandate and explore which of the generic barriers and drivers of BIM-readiness are more relevant to the design and construction of housing projects.

The purpose of this paper is to uncover the relationship between flows and real estate investment at open-ended real estate funds (OEREFs).

The study employs fixed-effects panel regressions, relying on data from the Hungarian fund managers’ trade association. First, the effect of lagged flows on allocation to real estate is assessed. Second, the paper studies how this relationship changes as the cyclical position of CRE market advances using two proxies.

Flows are found to affect funds’ real estate holdings if they occurred 12–18 months earlier. Inflows (outflows) in the preceding six months demonstrably lower (increase) funds’ real estate holdings ratio. Beyond this relationship, findings do not suggest that less funds are channelled to real estate as “CRE heat” intensifies.

In an environment marked by strong cash inflows, the investment lag can translate into a significant drop in funds’ exposure to real estate. The share of real estate at Hungarian funds in the sample, for example, fell from 79 to 50 per cent on average over the period of 2011–2017. Measures designed to limit inflows are in the interest of those existing investors who wish to avoid a dilution of the core investment strategy.

The paper adds to the literature on OEREFs which has been particularly scarce on liquidity transformation during non-crisis times and on non-German funds.

Research in tourism and hospitality industry marketing has identified many highly effective applications of social media. However, studies in the existing literature do not enable a comprehensive understanding of this phenomenon because they lack a theoretical foundation. Therefore, this study systematically reviewed the literature from the perspective of the task-technology fit (TTF) theory. The purpose of this paper is to map out what is known about social media use in tourism and hospitality marketing and what areas need further exploration.

A descriptive cumulative review of the literature obtained 99 articles published in tourism and hospitality journals from 2010 to 2019.

The analysis suggests that to understand social media use in tourism marketing, researchers and practitioners in the industry must clarify the following four issues: the control variables, longitudinal analyzes and TTF concepts that should be used in future studies; the fitness of social media platforms for tourism marketing; how various social media platforms differ in terms of performance outcome; and the digital divide in the use of social media for tourism.

An integrated framework was developed to identify constructs and to understand their relationships. Recent studies in this domain are discussed; theoretical and practical suggestions and implications for future research are given.

This paper aims to provide a foundation for firms trying to evaluate the suitability of Internet of Things (IoT)-enhanced offerings against the background of their current portfolio. Currently, quite a number of companies consider revising or extending their portfolio of products and services by incorporating IoT components to achieve competitive advantages. However, an unsystematic and autotelic addition of connected sensors and actuators to present offerings does not necessarily lead to substantial market success.

The approach of this paper is to identify different roles which IoT components can play in offering portfolios; clarify business development objectives, which can be achieved by the combination of products and services with IoT components; and report case examples which help to highlight how business development objectives can be reached with the help of IoT components fulfilling specific roles.

IoT components may play three different roles when integrated into product or service offerings. This role differentiation is crucial in understanding how IoT amendments can be instrumental in supporting the achievement of specific business development objectives pursued by a firm.

The framework is based on conceptual considerations. To overcome this limitation, empirical research on technology-, cost- and customer-related impacts of IoT-enhanced offerings is desirable.

Firms need to evaluate three roles which IoT components can play against the background of their present product portfolio when developing new business strategies.

This paper combines literature on the principles of operation of IoT applications and business models with current use-cases to provide implications for IoT-related business development issues.
