The concept of conventional place-based accessibility, despite being well researched, tends to ignore people’s space–time constraints arising from mandatory activities (e.g. work and household duties), which confine people’s potential movement and delimit the accessible opportunities. As people with different socioeconomic statuses may have different space–time constraints even while living in similar locations, using the place-based measures could lead to an underestimation of accessibility inequality. This study applies a space–time measure to unravel the disparities in service accessibility in suburban China. Since the late 1970s, suburbanisation in Chinese cities has fostered income inequality and has elevated other dimensions (e.g. institutional status and gender) of disparity within each income class. Within this context, we conduct a case study of suburban neighbourhoods in Guangzhou, based on the activity diary data derived from a home-based questionnaire survey. Findings indicate that the use of a space–time measure effectively captures the disparities in service accessibility among residents in suburban Guangzhou. On the basis of structural equation modelling, we further identify that certain socioeconomic groups (e.g. high-income residents, public sector workers, local hukou holders, male household heads and welfare housing residents) tend to experience fewer space–time constraints from rigid activities, such as work, commuting and household duties, and are thus more advantaged in accessing service facilities. These findings imply that urban planning should address the space–time perspective to promote equal service access for the highly heterogeneous social groups in suburban China and to incorporate time-sensitive policies (e.g. flexitime policies).

This chapter presents a case study of Isobord1, a Canadian manufacturer of high quality particleboard that uses straw instead of wood as the main raw material input. Isobord is facing critical operational problems that threaten its future. Gary Schmeichel, a biotechnology consultant hired by Isobord, must recommend how much straw collection equipment to purchase and what kind of information technology to acquire to help manage equipment dispatch operations. Schmeichel is exploring how geographic information systems (GIS) and relational database management systems (RDBMS) might help manage operations, but budget and time constraints and organizational inexperience seriously threaten these efforts. Decisions must be made immediately if there is to be any hope of implementing a system to manage the first year’s straw harvest. Readers are challenged to put themselves in Schmeichel’s shoes and prepare recommendations for Isobord.

Final Round

This case study is a reflective account of a consultation with a 30-year-old male professional golfer. The approach by the player was made on the evening prior to the final round of a European Tour event, needing a top-20 finish on the final day of the tournament year. Failure to achieve this objective would have resulted in forfeiting of his playing privileges on the PGA European Tour for the following season, with the associated loss of income and, in this case, genuine threats to his livelihood. The consultant used a number of interventions (e.g., best-performance imagery, external focus of attention, hypnosis, and music) and an approach established in humanistic, phenomenological, and transpersonal psychology. Effectiveness was determined by performance and the player’s descriptions of his transcendental experience. The client provided social validation for the consultation approach and the intervention through his reflections. The intervention in this case appeared to elevate positive emotions and trigger a transcendental precursor to peak performance. While this type of intervention may provide immediate performance benefits for golfers experiencing low self-confidence, the case study also illustrates how consultants are often asked to support athletes under severe time constraints.

Despite the prevalence of cloud and edge computing, ensuring the satisfaction of time-constrained business processes, remains challenging. Indeed, some cloud/edge-based resources might not be available when needed leading to delaying the execution of these processes? tasks and/or the transfer of these processes? data. This paper presents an approach for specifying, verifying, and deploying time constrained business processes in a mono-cloud, multi-edge context. First, the specification and verification of processes happen at design-time and run-time to ensure that these processes? tasks and data are continuously placed in a way that would mitigate the violation of time constraints. This mitigation might require moving tasks and/or data from one host to another to reduce time latency, for example. A host could be either a cloud, an edge, or any. Finally, the deployment of processes using a real case-study allowed to confirm the benefits of the early specification and verification of these processes in mitigating time constraints violations.

Study Results

Regression testing is a very important activity in continuous integration development environments. Software engineers frequently integrate new or changed code that involves in a new regression testing. Furthermore, regression testing in continuous integration development environments is together with tight time constraints. It is also impossible to re-run all the test cases in regression testing. Test case prioritization and selection technique are often used to render continuous integration processes more cost-effective. According to multi objective optimization, we present a test case prioritization and selection technique, TCPSCI, to satisfy time constraints and achieve testing goals in continuous integration development environments. Based on historical failure data, testing coverage code size and testing execution time, we order and select test cases. The test cases of the maximize code coverage, the shorter execution time and revealing the latest faults have the higher priority in the same change request. The case study results show that using TCPSCI has a higher cost-effectiveness comparing to the manually prioritization.

We steered this research to explore the recruitment and selection management of members based on interests applied by the selection team in the Arabic language student association. This research was a case study with a qualitative approach. The data were collected by interview, documentation, and observation. The results revealed that students who took part in the selection were classified based on their interests or skills through interviews and tests conducted by the selection team. However, the selection team experienced 2 obstacles: 1) time constraints during the selection process, 2) obstacles after the recruitment process. The first obstacle was when some students did not know what interests they have and the second one was when the members lost their motivation and commitment to learn. These obstacles affect other members and the learning process in the Arabic language student association. Therefore, the right recruitment process will attract more members that meet the qualifications and influence the student association. Then, in turn, it will make students more creative, explore themselves, become generation of achievers.

Crowdsourcing carried out by cyber citizens instead of hired consultants and professionals has become increasingly an appealing solution to test the feature rich and interactive web. Despite having various online crowdsourcing testing services, the benefits of exposure to a wider audience and harnessing the collective efforts of individuals remain uncertain, especially when the quality control is problematic in an open environment. The objective of this paper is to propose a real-time collaborative testing approach (RCTA) to create a productive crowdsourced testing on a dynamic Internet. We implemented a prototype crowdsourcing system XTurk, and carried out a case study, to understand the crowdsourced testers behavior, the trustworthiness, the execution time of test cases and accuracy of feedback. Several experiments are carried out and experimental results validate the quality, efficiency and reliability of the present approach and the positive testing feedback is are shown to outperform the previous methods.
