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.

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.

AbstractThe importance of knowledge and other intangible activities for the success of an enterprise have been broadly recognized over the last few years. In this paper a tutorial is illustrated on the valuation of a patent through the real options approach (ROA), since the use of the discounted cash flow (DCF) methods, such as the net present value (NPV), seems to show issues when evaluating opportunities, such as the ones offered by intangible activities. The logic underlying ROA is tightly based on financial options and, in this sense, uncertainty can be seen as an opportunity, and not necessarily as a threat and its effect on the value of an activity can become positive. The patent analysed (registered in 2009) is a patent by the Alfa Group (this is not the real name of the firm but is used here for privacy reasons), which is a worldwide leader in the production of Getters, metallic elements that, through a chemical absorption process, keep the devices in which they are embedded in vacuum status. Such equipment is used in lightning systems, monitor screens, flat screen TVs, etc. In this tutorial, an ROA has been developed in order to demonstrate how the value of intangible assets can be estimated by using an Italian case study that can be useful for further studies and uses.

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.

Word Representation

Deep learning has extensively been used in natural language processing with sub-word representation vectors playing a critical role. However, this cannot be said of Swahili, which is a low resource and widely spoken language in East and Central Africa. This study proposed novel word embeddings from syllable embeddings (WEFSE) for Swahili to address the concern of word representation for agglutinative and syllabic-based languages. Inspired by the learning methodology of Swahili in beginner classes, we encoded respective syllables instead of characters, character n-grams or morphemes of words and generated quality word embeddings using a convolutional neural network. The quality of WEFSE was demonstrated by the state-of-art results in the syllable-aware language model on both the small dataset (31.229 perplexity value) and the medium dataset (45.859 perplexity value), outperforming character-aware language models. We further evaluated the word embeddings using word analogy task. To the best of our knowledge, syllabic alphabets have not been used to compose the word representation vectors. Therefore, the main contributions of the study are a syllabic alphabet, WEFSE, a syllabic-aware language model and a word analogy dataset for Swahili.

PurposeThis study aims to evaluate a hydroponic farm (through nutrient film technique) while considering uncertainty, sustainability and the system's utility in the dominant desert geography. The idea of the hydroponic farm is to allow individuals/businesses to grow plants. Given the geographical condition, the hydroponic system may be useful in the Gulf context and may lead to food security and sustainability. Additionally, the UAE government has initiated several support schemes that can be availed for investing in such businesses that can contribute to the nation's food security.Design/methodology/approachThe hydroponic farm is evaluated using the net present value and real options approach. The authors studied five scenarios: 1. business as usual, 2. 50% subsidy on initial investment through Khalifa funding, 3. 4% premium, 4. Subsidy plus premium and 5. solar panel installation with bore well.FindingsAs per the assumptions and data usage, all the scenarios shows a positive net present value (NPV); Nevertheless, scenarios 4 and 5 report the significant highest net present and delay value.Research limitations/implicationsThis study has environmental, economic and social implications. Lower imports indirectly lead to lower carbon footprints. The local production of food ensures higher employability in the sector and increase in local consumption. Additionally, fresh food consumption is directly associated to good health.Practical implicationsSupportive policies such as subsidies through Khalifa funding may accelerate the expansion of such projects through domestic and foreign investments. One of the important takeaway from the study is to invest in the training of the workforce.Social implicationsGiven the geographical condition, the UAE usually depends on food imports. If the hydroponic farms become popular, the residents will have access to fresh vegetables and fruits. Higher engagement in agriculture activities also ensures a significant increase in agriculture-related businesses and higher employability.Originality/valueThe study adds novelty to the literature because the effect of Khalifa funding and investment analysis on solar (wells) has not been evaluated in any hydroponic studies. We presented the results with tornado graphs using NPV risk and real options approach in the Gulf context. The study represents functional scenarios that were previously not found in the literature.

AbstractDecision making in organic farming is related to risk and uncertainty, and options must be evaluated in the decision-making process. This paper presents the methodology of an integrated deterministic simulation system (KARSIM 1.0) application for decision-making support on organic farms in northeastern Slovenia. An emphasis to modify the net present value (NPVt) criterion by incorporating the real options approach was made. Its application is shown in organic spelt (Triticum aestivum ssp. spelta McKey) production and processing using two real options approaches, the Black–Scholes and binomial models. The NPVt indicates that the decision to process spelt for animal fodder is financially unfeasible, while the real options approach differentiates the results by organic spelt grain and flour production for human nutrition. It may be concluded that the real options approach can be useful when assessing projects with uncertainty, sunk costs and irreversibility, and it can provide for examining agricultural investment decisions.

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.
