Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

Data plays a critical role in organizations up to the point of being considered a competitive advantage. However, the quality of the organizations’ data is often inadequate, affecting strategic and tactical decision making, and even weakening the organization’s image. Nevertheless it is still challenging to encourage management to invest in data quality improvement projects. Performing a traditional feasibility analysis based on Return on Investment, Net Present Value, etc., may not capture the advantages of data quality projects: their benefits are often difficult to quantify and uncertain; also, they are mostly valuable because of the new opportunities they bring about. Dealing with this problem through a real options approach, in order to model its intrinsic uncertainty, seems to be an interesting starting point. This paper presents a methodological framework to assess the benefits of a Data Quality project using a real options approach. Its adequacy is validated with a case study.

This study assesses the quality of Chinese outbound FDI data. In our case study of the Netherlands, we checked the data quality of the often-used Orbis/Amadeus database and its data source, the Dutch Chamber of Commerce (Kamer van Koophandel, KVK), which has one of the oldest and, arguably, one of the better databases within Europe. We analysed Chinese investments in the Netherlands and show that six adjustments are necessary to clean up the data. We also show that not making these adjustments can significantly impact the outcome of research. The cleaned-up data show that sampled Chinese firms are young, small, and private.

Hajj guidance group (KBIH) in Indonesia, still limited to quantity and have been not yet met the quality. One indication of the lack of quality of the KBIH is the quality management of inputs, namely the applied inputs and inputs of expectation. With good input and good, it can produce an out put that as expected. This study aims to determine the quality management of pilgrimage inputs by KBIH in Indonesia, represented by three regions, West Java, DKI Jakarta and South Sumatra. The method used in this research is case study with qualitative approach. This study shows that quality management for one dimension of input, especially in KBIH has not met the quality management standard. Implementation and embodiment is still limited to ideas, wishful thinking, and not conceptualized well. The results of this study have an impact on how the quality management of KBIH input in Indonesia should be implemented, so that with good input in KBIH, KBIH can improve the quality of Hajj in Indonesia. Input is a starting point in a quality assurance process, not to be ignored, underestimated, and considered not one of the important parts of quality management of its existence.Kelompok Bimbingan Ibadah Haji (KBIH) yang banyak berdiri di Indonesia, masih sebatas kuantitas belum memenuhi kualitas. Salah satu indikasi melihat kurangnya kualitas KBIH ialah pada manajemen mutu input, yaitu input terapan maupun input harapan. Dengan input yang baik dan bagus, maka bisa menghasilkan out put yang sesuai harapan. Penelitian ini bertujuan untuk mengetahui manajemen mutu input penyelenggaraan haji oleh KBIH di Indonesia, yang diwakili tiga wilayah, Jawa Barat, DKI Jakarta dan Sumatera Selatan. Metode yang digunakan dalam penelitian ini adalah studi kasus dengan pendekatan kualitatif. Penelitian ini memperlihatkan bahwa manajemen mutu untuk satu dimensi input, khususnya di KBIH belum memenuhi standar manajemen mutu. Pelaksanaan dan perwujudannya masih sebatas ide, angan-angan, dan belum terkonsep dengan baik. Hasil penelitian ini berdampak pada bagaimana manajemen mutu input KBIH di Indonesia seharusnya diimplementasikan, sehingga dengan input yang baik dalam KBIH, KBIH bisa meningkatkan kualitas penyelenggaraan ibadah haji di Indonesia. Input merupakan starting point dalam sebuah proses jaminan mutu, jangan sampai diabaikan, disepelekan, dan dianggap bukan salah satu bagian manajemen mutu yang penting keberadaannya.

Location is considered as an important element in studying tourism security. Therefore, mapping crime hotspots has recently been an interesting research topic in tourism development. In order to identify crime patterns and hotspots, it is essential to create a database containing the required spatial data. It should also be integrated with additional qualitative/quantitative attributes affecting criminal actions. Designing a geographic information system (GIS) can be considered as the most efficient way to deal with this problem considering the complex nature of tourism security. This paper presents the theoretical scheme of spatial data modeling with the purpose of indentifying potential crime zones within a developed park. From the spatial point of view, the factors and the constraints, which make a location vulnerable, are defined. The entities are identified by their attributes and characterized by their relationships. Finally, the conceptual and the logical models to create the crime suitability maps are generated. The models provided in this paper are designed in an explicit way; therefore, they can be easily modified or generalized for any specific case study. The presented data modeling procedure can be applied to generate essential databases for crime mapping via any GIS software.

A orientação espacial se relaciona aos processos cognitivos, perceptuais e comportamentais pelos quais uma pessoa passa para achar seu caminho desde o ponto de partida até seu destino final. Por entender que o ambiente nem sempre está adequado e contribui para as tomadas de decisão durante este processo, esta pesquisa possui como objetivo avaliar as estratégias de orientação espacial e wayfinding de alunos no campus da Universidade Federal de Santa Catarina, em Florianópolis/SC, a partir de uma rota pré-estabelecida. Foram selecionados dois métodos para pesquisa. O primeiro, consistiu na produção de Mapas Mentais do campus universitário pelos participantes da pesquisa, e o segundo, na aplicação do método Passeio Acompanhado. Ao longo do percurso os participantes encontraram dificuldades em encontrar o destino final, demonstrando que os recursos gráficos não estavam dispostos em locais estratégicos, e a quantidade/qualidade dos recursos atuais é insuficiente. Ao final são propostas algumas recomendações – espaciais – que melhorem o deslocamento dos usuários no campus universitário.                  *****Spatial orientation process is related to the cognitive, perceptual and behavioral process that a person goes through to find his way from the starting point to his final destination. By understanding that the environment is not always adequate and contributes to decision making during this process, this research aims to evaluate the spatial orientation and wayfinding strategies of students on the campus of the Universidade Federal de Santa Catarina, in Florianópolis/SC, from a pre-established route.Two research methods were selected. The first consisted of the production of Mind Maps on the university campus by the research participants, and the second, the application of the Accompanied Stroll method. Along the way, the participants found it difficult to find the final destination, demonstrating that the graphic resources were not available in strategic locations, and the quantify/quality of current resources is insufficient. At the end, some recommendations are proposed – spatial – that improve the displacement of users on the university campus.

Although by many perceived as important, spatial data quality has hardly ever been taken centre stage unless something went wrong due to bad quality. However, we think this is going to change soon. We are more and more relying on data driven processes and due to the increased availability of data, there is a choice in what data to use. How to make that choice? We think spatial data quality has potential as a selection criterion. <br><br> In this paper we focus on how a workflow tool can help the consumer as well as the producer to get a better understanding about which product characteristics are important. For this purpose, we have developed a framework in which we define different roles (consumer, producer and intermediary) and differentiate between product specifications and quality specifications. A number of requirements is stated that can be translated into quality elements. We used case studies to validate our framework. This framework is designed following the fitness for use principle. Also part of this framework is software that in some cases can help ascertain the quality of datasets.

Nowadays, more and more organizations are realizing of importance of their data, because it can be considered as an important asset in present nearly all business organizational processes. Information Technology Division (ITD) is a department in the International Islamic University Malaysia (IIUM) that consolidates efforts in providing IT services to the university. The university data management started with decentralized units, where each center or division has its own hardware and database system. Later it improved to become became centralized, and ITD is now trying to one policy across the whole university. This will optimize the high performance of data management in the university. A visit has been done to ITD building and a presentation has been conducted discussing many issues concerning data management quality maturity in IT division at IIUM. We got some notices like server’s room location, power supply and backup and existence of data redundant. These issues are discussed in details in the next sections of this paper and some recommendations are suggested to improve data quality in the university. The quality of the data is very important in decision making, especially for a university that is trying to improve its strategy towards a research university and rise its rank among the World University Ranking.

Purpose This paper aims to know how university’s strategic managers, from botacademic and administrative systems, perceive the relationship between sustainability and accreditation as sustainability incorporation and the quality of their processes are amongst the actual challenges of universities. Design/methodology/approach This paper opted for an inductive, exploratory study using the case study approach, including 19 in-depth interviews to administrative and academic managers in a private, high-quality certified university in Colombia. The data were assessed using the content analysis methodology. The Colombian accreditation guidelines were the base to analyse the data as accreditation is part of the quality assurance system. Findings This paper provides empirical insights into how the implementation of sustainability in universities relates to the Colombian accreditation factors. The main links found were in the areas of the university’s social impact and organisational responsibility, which are highly relevant to graduates, external stakeholders and sustainability skills. Sustainable campus operation was associated with environmental management and improvement of the quality of the physical plant, with social and economic benefits in the long-term. Additionally, this research found a need for administrative and academic managers to understand and increase their commitment to sustainability. Research limitations/implications Because it was a case study, results are not generalisable. Consequently, further research on similar lines is required to universalise the mentioned observation and results. Practical implications The accreditation factors related to sustainability, inductively defined and exposed in this paper, provide an idea of how sustainability implementation could contribute to higher education quality assurance. Originality/value This paper contributes to filling the knowledge gap about embedding sustainability in Latin-American universities. This paper postulates a starting point considering accreditation standards and the link of the strategic manager’s perceptions of sustainability.

Built heritage resources (BHRs) are multidimensional assets that need to be conceived under a sustainability and circular economy framework. Whereas it is essential that their conservation, management, and enjoyment are sustainable, it is also necessary that the environmental, cultural, and socio-economic contexts in which they are integrated are sustainable too. Like other amenities, BHRs can improve the quality of the urban environment and generate externalities; additionally, they may influence sectors such as real estate, hospitality, and tourism. In this framework, this contribution aims to identify spatial relationships occurring between BHRs and short-term rentals (STRs), i.e., a recent economic phenomenon facilitated by platforms such as Airbnb. Through the application of Exploratory Spatial Data Analysis techniques and taking Turin (Italy) as a case study, this article provides evidence that spatial correlation patterns between BHRs and STRs exist, and that the areas most affected by STRs are the residential neighborhoods located in the proximity of the historic center of the city. Relations with other sets of socio-economic variables are highlighted too, and conclusions suggest that future studies are essential not only to monitor sustainability issues and reflect on new housing models and sustainable uses of buildings, but also to understand the evolution of the phenomenon in light of the pandemic Covid-19.
