The study describes the development of an instrument, to measure NOS understandings of science teachers and a subsequent pilot study to test the instrument. The pilot measured NOS understanding of two teachers using a questionnaire that had been developed by the researcher. The objective of the study was to construct a questionnaire that could measure NOS understanding based on the family resemblance approach (FRA). The NOS is a construct that has been defined by various scholars and there exists multiple perspectives. For this study, two schools of thought defining the nature of science: the consensus view (CV) and the reconceptualized family resemblance approach to NOS (RFN) were considered. The CV has been widely accepted for years to represent the NOS through its tenets, and there exists reliable tools to document NOS. Based on the CV researchers developed an instrument, views of nature of science (VNOS), to document NOS understanding. In the past decade, scholars have challenged the CV of NOS and highlighted shortcomings in its tenets. FRA was developed that depicts science in a holistic system with dynamic interactions unlike the CV that represents NOS as independent tenets. From FRA, emerged RFN consisting of social and cultural categories that affect how science is done. The approach of RFN due to its holistic approach will be preferred in this study. The authors of RFN developed a RFN questionnaire to assess views about NOS using a Likert scale. Due to the limitations of the Likert scale, an open-ended approach is preferred in the qualitative analysis of views of NOS as is found in the VNOS form. To collect data on NOS understanding, the researcher compared VNOS and the RFN questionnaire and developed an integrated family VNOS (IFVNOS) questionnaire. The IFVNOS questionnaire was administered in a pilot test followed by interviews to elaborate on responses. The responses were analysed by two coders and triangulated to ensure reliability. The responses were allocated codes to document NOS understanding, on a range from naïve to explicit understanding. The findings revealed that the IFVNOS questionnaire developed can be used as a tool to measure NOS understanding and more testing is required to assess reliability.

The three works reviewed in this article address Eurasia in different periods and different areas of concentration. Each one provides valuable information in understanding the historical and political developments that have affected the Eurasian landmass. Understanding this huge geography, its people, its past and present situation require a holistic approach with detailed knowledge and awareness of regional peculiarities.

Digital manufacturing has been challenged by the manufacturing industry to rationalise different ways to connect and to exchange information and knowledge across the manufacturing systems. One of the main pillars of the Industry 4.0 concept is the horizontal and vertical integration with intelligent and self-adaptive systems. For this to be possible, the manufacturing industry applies an extensive range of software tools to aid its activities, such as SCADA, MES, ERP, 3D CAD, CAM, and so on. Individually, each one performs its function to support the manufacturing process. However, these software tools do not have an effective integration and interoperation, since they present different database structures, variables that have the same information with different names and data structures, and closed systems. Thus, it has been identified semantic interoperability issues (misinterpretations and mistakes) in view of the information heterogeneity from multiple perspectives and their relationships across the manufacturing process. In this context, this paper aims to present a discussion of interoperability issues across the manufacturing systems, as well as to introduce possible solutions according to the related works. a holistic approach is critical factors for long-term competitiveness solutions. The literature points out that the solution to this problem may be in the application of semantic technologies. These have the potential to provide solutions that are more comprehensive than the industrial approaches that have been applied through the formalization of information so that knowledge can be shared among multiple domains.

Since multiple perspectives and dynamic national environments can be applied to explain how value is created in an international context, multinational firms need analytical guidelines when facing procurement and production decisions concerning various worldwide locations for value-added chain activities such as marketing, production, distribution, and after sales service. The ultimate aim of this research was to abstract and empirically test a realistic but fairly simple localization framework to facilitate the design of an information system that supports a cost-benefit analysis based on legal requirements, value chain activities, and product costs. A balance was sought between inclusiveness and minimalism in the development of a normative model for implementation of dynamic strategic planning and control programs. The data show the participants behavior is significantly influenced by all three elements supporting the value-added localization model and validating the holistic approach put forth by Lecraw & Morrison (1991).

With the rapid proliferation of Internet of Things (IoT) into urban people’s everyday walk of life, the functions of smart cities are fast approaching to be embedded in every step of people’s life. Despite the concept of smart cities founded in the late 1990s, there has been limited growth until recent popularity due to the advancements of IoTs. However, there are many challenges, predominantly people-centric, that require attention for the realisation of smart cities and expected real-life success. In this paper, we intend to investigate the state-of-the-art focus of smart cities from three angles: infrastructure engineering, information technology and people-centric management. We adopt a mixed-methods analysis of currently published literature on the topic of smart cities. Our study attempts to draw attention to the need for developing smart cities with a holistic approach involving multiple perspectives rather than a siloed emphasis on technology alone. We highlight that the fields of specialisations such as information technology and infrastructure engineering in contributing to smart cities need a cross-domain holistic approach of managing people-centric service requirements for improving consumer satisfaction and sustainability.

Pediatric voice disorders are typically a low-incidence population in the average caseload of clinicians working within school and general clinic settings. This occurs despite evidence of a fairly high prevalence of childhood voice disorders and the multiple impacts the voice disorder may have on a child's social development, the perception of the child by others, and the child's academic success. There are multiple barriers that affect the identification of children with abnormal vocal qualities and their access to services. These include: the reliance on school personnel, the ability of parents and caretakers to identify abnormal vocal qualities and signs of misuse, the access to specialized medical services for appropriate diagnosis, and treatment planning and issues related to the Speech-Language Pathologists' perception of their skills and competence regarding voice management for pediatric populations. These barriers and possible solutions to them are discussed with perspectives from the school, clinic and university settings.
