Abstract. CityGML model-based is now a norm for smart city or digital twin city development for better planning, management, risk-related modelling and other applications. CityGML comes with five levels of details (LoD, in version 2.0) of buildings. The LoDs are also known as pre-defined multi-scale models requiring a large storage-memory-graphic consumption than a single scale model. LoD CityGML models are primarily constructed using point cloud measurements and images of multiple systems, resulting in a range of accuracies and detailed model representations. Additionally, it entails several software, procedures, and formats for the construction of the respective LoDs prior to the final result in the CityGML schema. Thus, this paper discusses several issues of accuracy and consistency, proposing several quality controls (QC) for multiple data acquisition systems (e.g. airborne laser systems and mobile laser systems), model construction techniques (e.g. LoD1, LoD2, and LoD3), software (interchange formats), and migration to a PostgreSQL database. Additionally, the paper recommends the importance of minimising implementation errors. A scale-specific unique identifier is introduced to link all associated LoDs, enabling cross-LoD information queries within a database. Proper model construction, accuracy control, and format interchange of LoD models in accordance with national and international standards will undoubtedly encourage and expedite data sharing among data owners, agencies, stakeholders, and public users. A summary of the work and accomplishments is included, as well as a plan for future research on this subject.

Dynamic Consent

AbstractThe complexities of the informed consent process for participating in research in genomic medicine are well-documented. Inspired by the potential for Dynamic Consent to increase participant choice and autonomy in decision-making, as well as the opportunities for ongoing participant engagement it affords, we wanted to trial Dynamic Consent and to do so developed our own web-based application (web app) called CTRL (control). This paper documents the design and development of CTRL, for use in the Australian Genomics study: a health services research project building evidence to inform the integration of genomic medicine into mainstream healthcare. Australian Genomics brought together a multi-disciplinary team to develop CTRL. The design and development process considered user experience; security and privacy; the application of international standards in data sharing; IT, operational and ethical issues. The CTRL tool is now being offered to participants in the study, who can use CTRL to keep personal and contact details up to date; make consent choices (including indicate preferences for return of results and future research use of biological samples, genomic and health data); follow their progress through the study; complete surveys, contact the researchers and access study news and information. While there are remaining challenges to implementing Dynamic Consent in genomic research, this study demonstrates the feasibility of building such a tool, and its ongoing use will provide evidence about the value of Dynamic Consent in large-scale genomic research programs.

PurposeThis inquiry aims to determine the features and mechanisms that specially enable a multiteam system (MTS) to develop ambidexterity that can deal effectively with rapid changes in dynamic environments. The MTS is an emerging organizational unit comprised of tightly integrated networks of teams that may originate from one or more firms. The inquiry also considered how an MTS can engage those features and mechanisms to maximize ambidexterity as dynamic capabilities for increased innovation and long-term adaptation under complex, volatile conditions.Design/methodology/approachThis conceptual inquiry integrates the emerging research on MTSs with theory and studies relating to ambidexterity and dynamic capabilities. This inquiry focuses on the attributes and linkages that specially characterize an MTS. It analyzes these to determine the key mechanisms and interactions enabling and engaging ambidexterity at MTS unit level.FindingsMTSs can engage powerful mechanisms for ambidexterity functioning as dynamic capabilities at meso-organizational level. The attributes and linkages that distinguish an MTS from other units enable it to deal effectively and efficiently with near-term task demands by simultaneously balancing the essential tasks of exploration and exploitation, and by being able to rapidly adapt by reconfiguring taskwork and reallocating resources as required for sustainable innovation and long-term success within a dynamic environment.Practical implicationsThis inquiry provides valuable insights for designing MTSs that are equipped with selected teams, flexible memberships, specialized skills and permeable interfaces. Autonomy for an MTS allows the unit to span internal and external organizational boundaries to gain access to new discoveries and to exchange information and material resources for increased innovation. Ambidexterity as dynamic capabilities facilitates exploitation of current resources by efficiently reconfiguring taskwork and reallocating materials for adaptation and competitive advantage.Originality/valueThis inquiry appears to represent the most integrative effort to examine the underexplored potential of MTSs for developing and engaging ambidexterity functioning as dynamic capabilities. The inquiry appears to be a first effort at articulating a concept of MTS ambidexterity distinct from organizational ambidexterity. The analysis synthesizes a systems model that guides organizational leaders and opens new opportunities for future research.

Proactive Measures

Some institutions provide online courses to students to ease the courses’ workload. Online courses can also be convenient because the online course content management software conducts marking of tests and examinations. However, a few students could be willing to exploit such a system’s weaknesses in a bid to cheat in online examinations because invigilators are absent. Proactive measures are needed and measures have to be implemented in order to thwart unacceptable behaviour in situations where there is little control of students’ conduct. Digital Forensic Readiness (DFR) employs a proactive approach for an organisation to be forensically prepared for situations where there is little control over people. This can be achieved by gathering, storing and handling incident response data, with the aim of reducing the time and cost that would otherwise be spent in a post-event response process. The problem this paper addresses is that, at the time of writing this paper, there existed no known DFR architecture that can be used to collect relevant information for DFR purposes, specifically in the course of an online examination, as described in the standard published by the International Standards Organisation (ISO) and the International Electrotechnical Commission (IEC) (ISO/IEC 27043:2015) for incident investigation principles and processes. Due to the lack of DFR architecture, the authors propose an Online Examination Digital Forensic Readiness Architecture (OEDFRA) that can be used to achieve DFR when online examinations are conducted. This architecture employs already existing DFR techniques, discussed in the study, to help educational institutions achieve DFR in online examinations. This architecture, (OEDFRA), when implemented, will be tested in future research in order to confirm its contribution to the field of DFR.

The condition of Indonesia is currently being faced by the corona virus (COVID-19) pandemic 2019. The importance of solutions related to the existence of the role of teachers or educators to provide references such as social support to students in learning and teaching activities from home, this study conducted to provide research tools or instruments that can be used by educators or researchers by testing the validity of a social support construct (Social Provision Scale) measuring instrument using the Rasch Model. Although much has been done to test the validity of the Social Provision Scale, no one has examined it by involving social support in the context of Education. Likewise, the majority of research on social support uses confirmatory factor analysis, and no one has used the Rasch Model in validating the Social Provision Scale instrument, especially in Indonesia. The data used are secondary data from Putra of 326 people in SMA Negeri 29 South Jakarta using cluster sampling. The results of the application of the Rasch Rating Scale model show that the psychometric characteristics of the Social Provision Scale are very good and precise, as well as the compatibility of the items to the model. Implications and suggestions for future research are also discussed.

Contemporary prosperity depends on effective and secure supply chain networks that support economic competitiveness. Disruptions in global supply chains would have critical consequences on economies. The lack of technical studies and quantitative data concerning security that affects supply chain operations in Latin America, motivated to develop an exploratory study. Considering the complexity of the question studied, this paper details a set of case studies that explore, from a qualitative research approach, to what extent fulfilling security international standards now necessary to access mature markets such as the U.S and Canada allows export companies located in emerging countries as Mexico to face effectively the different types and levels of local risk. These results should help both academics and practitioners to more readily understand, first, the key logistics components now taken into account when improving security in export-oriented supply chains is required, and second, decision-makers' perspectives regarding supply chain security standards (SCSS) available on the market. A discussion of results is exposed and finally, discussion and future research are presented.

With the rapid development of information and communication technology, physical space has been increasingly enhanced by digital technology. The way people and space interact is significantly changed. In particular, an increased interest in the notion of place has emerged in examining smart city development, digital engagement, and people–technology relationships in hybrid physical–digital space. In this article, a place-centric perspective is employed to investigate digitally enhanced people–space interactions. Based on a multimethod research design that combines physical survey, field observation, and interview, this research employs a case study of a shopping mall to examine people’s everyday practices of digitally enabled placemaking. It is found that a range of digital interfaces functions as a system at various proxemic scales in hybrid space, which open up new spatialities by mediating trans-scale placemaking practices. Type-forms of digitally enabled people–space interactions are also summarized. The paper concludes that digitally enabled placemaking in this particular case is constituted within a closed mechanism. Future research directions are also raised at the end.
