The purpose of this paper is to answer the question asked by Buelen “What do we still need to learn about outsourcing across time zones?”.

This paper serves as a response to the commentary by Erik Beulen in SOIJ Vol. 5 No. 1 titled “I'm working while they're sleeping: time zone separation challenges and solutions”.

The paper finds that we are still very much at the beginning of the “era of time zone dependent work.”

This futures analysis leads to the projection that many more individuals will be entering time zone dependent work. While technology may elevate some of the hardships of temporal separation, it will exacerbate others.

This paper aims to strive to model virtual trade resulting from time zone differences in an otherwise Heckscher–Ohlin set up which is absent in the literature. So, the paper adds some value to the existing literature on time zones (TZ) and trade.

A competitive general equilibrium model is developed first to capture the effect of TZ differences on virtual trade. Then the authors examine, in brief, if distance can be accommodated in such framework. Finally, the authors extend the model to incorporate informality.

It is seen that exploitation of time zone difference benefits skilled labor and hurts capital under reasonable assumption. In what follows, time zone difference exploiting sector expands, whereas the other sector contracts. Then, the model has been extended to examine how distance may also lead to similar outcomes. In addition, the model is further modified to explore the effect of virtual trade in an informality and associated extortion ridden economy. Interestingly, virtual trade turns out to be beneficial to unskilled workers as well, and leads to a fall in the number of extortionists, though informal production is augmented.

This model is a competitive model that may not clearly reflect the realistic world. However, interestingly this may form the basis of looking into some other appealing dimensions of the real world.

TZ and related communication-cost-driven trade arguments are relatively less explored theoretically. Therefore, the work adds some value to the theoretical understanding of outsourcing in service trade that uses day-night differences across the globe.

The purpose of this paper is to understand different aspects of structural dispersion in virtual teams (VTs). The study measures five types of dispersion, their impact on VT performance and the moderating effect of electronic communication.

The authors collected data from 44 globally distributed VTs representing 403 members. The authors used details of the members’ locations to measure five elements of dispersion for each team: spatial, time-zone, number of locations, extent of numerical balance across locations and extent of isolated members for a team. The authors used two items to assess effective electronic communication and measured team performance on four items from three sources – members, leaders and third-party stakeholders.

Using regression, the authors found that the number of sites, degree of team balance and isolation had a negative impact on team performance. Spatial and temporal dispersion did not impact performance. Effective electronic communication moderated the relationship of team performance with team balance and the number of sites.

Study presents novel findings on the role of team configuration in VTs. Limitations: the study provides pointers to the likelihood of a non-linear relationship between spatial distance and performance; however, the scope of the paper does not permit an examination of this model. Future research can study this relationship. Second, the study does not examine how team configuration impacts the team processes that discount performance. Finally, the study treats each index of dispersion as independent of the others. The analysis does not study the interplay between and among the indices.

The findings provide clear indicators for managers and researchers of VTs on the issues associated with the location and configuration of the teams. Managers, while designing and managing dispersed members are now informed of the impact of the number of sites and the sub-group dynamics. The study underscores the importance of effective electronic communication in managing dispersion.

The study presents how faultiness based on location of VT sub-groups (as represented in the configuration of a team) can hamper performance. Literature suggests that this faultiness can also extend to social identities (based on gender, culture, etc.). The indicators provided by this study in this respect provide a topical focus for research because diverse dispersed teams are becoming more prevalent.

The study is the first empirical exploration of dispersion in VTs beyond the traditionally acknowledged dimensions of spatial distance and time-zones. It is a timely response to the recent trends in literature. Additionally, the study derives data from a unique data set of global VTs, thus making findings easily generalizable.

As part of an exploratory study on the nature of global leaders' power, we interviewed 23 global leaders to address the question: “How do the task, culture, and relationship complexities of global leadership shape the way global leaders exercise power and influence their followers?” We identify five complicating factors that shape the use of power by global leaders: Language, culture, time zones, physical distance, and matrix organizational structures. When compared with domestic leaders, these five factors make the use of power more complex for global leaders and require global leaders to invest substantially more time and energy into building relationships, sharing leadership, and prioritizing communication to ensure common understanding of vision and goals. We highlight a sixth factor, high-quality relationships, as an enabling resource for global leaders to succeed despite contexts of global leadership complexity. We provide a conceptual model summarizing how global leader influence attempts are complicated and enhanced and offer implications for future research and practice.

The main objective of the present research is to depict the experience of challenges and opportunities for virtual accreditation peer review team (PRT) visits. COVID-19 has changed higher education delivery. Higher education accreditation and PRT visits have become online. The lockdown forced schools and accreditation agencies to cancel or change visit arrangements. PRT visits could not be stopped during the COVID-19 pandemic, but accrediting agencies needed to review programme quality to meet standards.

Eight former and present accreditation specialists were interviewed. The researchers described the challenges and opportunities in virtual accreditation visits (VAV). Also, the authors have explained their own experience of coordinating on-site and virtual accreditation visits. Using the NVIVO tool, the experts' replies are transcribed and categorised as challenges and opportunities.

The findings will help the professionals and academicians better prepare for, plan and execute virtual PRT visits for accreditation agencies and schools. The results revealed that the evaluation and accreditation outcomes are similar for virtual and physical accreditation visits. Finally, the findings suggest that accreditation agencies and schools need to adopt a hybrid site visit model for accreditation visits.

The school can prepare better for virtual PRT visits by identifying the challenges and opportunities ahead of time. The finding may motivate authorities to schedule meetings in different time zones, prepare document evidence rooms, save money, time, and travel time, and benefit the environment by eliminating paper printing, fuel use, and paper printing.

This research is unique and noteworthy since accreditation organisations, PRT members and schools are uncertain about virtual visits. This may be the first paper in this domain to assist accreditation organisations and institutions review accreditation visits online or in hybrid mode.

This paper presents a case study on the problem of loading air containers in air express carriers motivated from DHL and Air Hong Kong. The problem is to determine the containers to be loaded and the locations of the loaded containers in an aircraft while maintaining stability of the aircraft. The objective of the problem is to maximize the revenue obtained from delivering containers. We present an integer programming model to represent and optimally solve the problem. Computational experiments done on a number of randomly generated test instances show that the integer program can be a viable tool for generating loading plans in the companies since optimal or near-optimal solutions for the test instances are obtained within a reasonable amount of computation time.

This paper aims to focus on time-related factors influencing on an itinerary planning system. The research objective is to produce an itinerary planning system which balances between the limited time of traveler and the number of tourist attractions they can visit. This system should facilitate travelers by presenting candidate itineraries that visit attractions as much as possible under several time-related factors.

To achieve the goal, an itinerary planning system has been designed and developed. The system considers several time-related factors including acceptable total travel time specified by travelers, time-related factors at an attraction (e.g. time zones, opening hours and visiting time) and time-related factors of traveling (e.g. road obstructions, weather, date and time and rest time). A routing algorithm which is aware of these time-related factors has been introduced to find candidate itineraries.

The performance of developed itinerary planning system has been evaluated by measuring speed and accuracy of seven traveling situations under different time-related factors. The experimental results indicate that the proposed routing algorithm spends less planning time than the traditional exhaustive routing algorithm. The efficiency of the proposed algorithm over the exhaustive algorithm is approximately 46 per cent while the accuracy is equal. Additionally, this designed system is evaluated by usability testing from nine experts. The evaluation is performed by measuring the user satisfaction level with the ability of user–system interaction. The results show that the overall system usability is in very satisfied level.

The designed itinerary planning system has three limitations. First, Google maps technology could not find information of some tourist attractions because these places were marked with several coordinates on the map. Second, holiday periods are manually kept into the database of system; therefore, it is necessary to annually and manually update the information. Third, the developed system is an online planner; thus, the speed of system depends on the bandwidth of users.

The designed itinerary planning system considers time-related factors as much as possible and more than the existing planning systems. This implies that the designed system is one of the most accurate planning systems in practice. Thus, the tourism business could rely on the developed itinerary planning system to help travel agents plan a travel itinerary properly and receive an accurate and up-to-date travel explanation to their customers.

This research proposes the novel design and implementation of an itinerary planning system which can suggest candidate itineraries, which visit maximum attractions under several time-related factors.

The purpose of this paper is to examine the proportion and distribution of organic produce sold through different marketing channels by a sample of organic farmers in three “core” areas of organic farming in England and Wales. More specifically, it conducts a quantitative analysis of marketing concentration and geographical dispersion within different travel time zones.

A quantitative database was constructed on the marketing channels and travel time zones used by 61 organic farmers to sell their produce and purchase necessary inputs. Indices of marketing concentration and geographical dispersion (outputs and inputs) were then calculated for each farm and region.

Results indicate a high level of marketing concentration, dominated by marketing cooperatives, direct marketing and abattoir/processors. Similar levels of concentration are recorded for the indices of geographical dispersion (especially outputs). Results vary significantly between the three regions, but it is clear that organic farmers in each region make use of different combinations of marketing channels, both local and national, in increasingly hybridised and individualised supply chains.

Many organic farmers are developing hybridised supply chains, including both local and more conventional marketing channels, and further research is needed into the identified regional differences and the reasons for developing what are often very individualised marketing chains.

This is the first attempt to calculate indices of marketing concentration and geographical dispersion for organic farms in different regions of England and Wales. The paper also contributes to debates on the potential impact of organic farming on rural development and the local economy.
