Development of a project delivery model for Umgeni Water : infrastructure projects
Authors:   , Naidoo Ashok Deenadayalan
Published: June 2022

Project delivery challenges encountered within the built-environment is a global phenomenon. Factors causing project delivery challenges in construction projects differ between countries, due to various fundamental reasons. The fundamental reasons that could exert an influence on project delivery challenges could extend into numerous causes relating to; the client, project planning, risk management, cost estimating, communication, quality and project management approach. The construction industry is a key component to the economy, however many construction infrastructure projects are hindered because of project delivery challenges and fail to be delivered successfully. This study aims at identifying lack of performance and its effects on project delivery for construction infrastructure projects and to develop a project delivery model to mitigate or minimise these challenges for Umgeni Water. A typical Likert Scale using a five-point gauge statistical tool was used for the data analysis. The sample population derives from Umgeni Water employees involved in the planning and implementation of construction infrastructure projects. The sample group consists of qualified and experienced professionals that are project managers, civil engineers, planning engineers, quantity surveyors, servitude administrators and environmental project managers. Findings that were identified as major project delivery challenges at Umgeni Water include the following; • Insufficient planning and designing done during the project, communication problems within the project; • Inadequate attributes and capabilitii;is endorsed by the project manager that hinder the implementation of a good project management approach; • Inadequate participation and contribution by the client during the project; • Project risks that are poorly identified assessed, mitigated and controlled during the project; • Unsatisfactory cost estimating resulting in errors and oversights, and • Oversight of critical quality factors during the project. Recommendations include: (1) the project team must ensure that ample effort is applied at the beginning of the project, sufficient time must be allocated to successfully complete the planning and designing process and consultants must be selected on their experience rather than low bidding; (2) the following courses / modules are recommended for inclusion in built environment tertiary education programmes for all disciplines. They are: design management, quality management, cost management, operational management, resource management and project management; and (3) the model developed should be adopted for use at Umgeni Water for the delivery of projects to minimise project delivery challenges.

Re-Shoring Advanced Semiconductor Packaging
Authors: VerWey John
Published: June 2022

The semiconductor industry and the U.S. government are engaged in ambitious plans to expand domestic semiconductor manufacturing capacity. Previous CSET research has found that the CHIPS for America Act incentives, if carefully targeted and augmented by adequate regulatory and workforce support, could reverse the observable decline in U.S. semiconductor manufacturing capacity since 1990. This paper argues that targeted investment incentives to increase U.S.-based advanced packaging capacity are also important for innovation, supply chain security, and ongoing semiconductor industry leadership.
Short-term financing and the impact of trade credit on the profitability of small and
medium enterprises in the Republic of Croatia
Authors: Prša Darija , Orsag Silvije , Milun Toni
Published: June 2022

Purpose: The establishment of credit policy is an integral part of the entire decision-making process on the manner and structure of corporate financing. Determining the credit policy is crucial for adequate management of a company’s net working capital and its financing, in order to support continuous operation and the earning capacity of the company. In this process, the company will be influenced by the market in which it operates and by many others external and internal factors. For example, companies operating in less developed financial markets will find it more difficult to obtain the necessary financing. Such companies are most dependent on short-term financing in general, and trade credit in particular. This paper analyzes primarily internal factors - trade receivables and payables. Accordingly, the main goal of this paper is to investigate the relationship between the profitability of SMEs in the Republic of Croatia and their use of trade credit. Methodology: In order to achieve the main goal and prove the hypotheses, panel data analysis examined the impact of trade credit on the level of profitability of Croatian SMEs. Results: The results show that delaying payments to suppliers increased the profitability of the company. Furthermore, the results show that a decrease in receivables did not increase the profitability of SMEs. Conclusion: Croatian SMEs can increase the profitability by not delaying the payment of obligations to suppliers for too long.
Quantifying the optimal long-run level of government expenditures in Turkey
Authors: Can Cansun Kemal , Aktaş Emin Efecan
Published: June 2022

Purpose: This paper gauges the nexus between government expenditures and the output level in Turkey. Our primary research objective is to evaluate the extent to which government expenditures give rise to an increase in GDP taking the Armey curve theory as a basis for the analysis. Succinctly speaking, this theory suggests that the expansionary impact of government expenditure on income level has diminishing nature and beyond a certain threshold public spending impairs rather than accelerates economic activities for several reasons including crowding out, rent-seeking, tax hikes, and public debt surges. Methodology: In order to test the validity of this theory, we use a dataset with annual frequency covering the 1968-2019 period, which is the longest dataset used to carry out this analysis in the literature for Turkey. We set up an ARDL model to estimate the long-run coefficients required for quantifying the optimal level of government spending in Turkey. Results: According to our findings, the estimated function exhibits a concave down functional form, which implies a diminishing marginal effect of government spending on GDP, suggesting thereby that the Armey curve theory is valid for Turkey. In addition, even though government expenditure has topped out in recent years, it is still below the GDP maximising optimal level, which indicates that there is sufficient room for expansionary fiscal policies, with the caveat of a potential negative marginal impact on GDP once the optimal threshold is exceeded. Conclusion: The long-run coefficients from the ARDL estimation reveal that despite a consistent upward trend, government expenditures are still below their optimal level, which implies that there is fiscal space available to the government as far as output maximisation is concerned. However, government expenditures have been on a downward trend recently, which is contrary to output maximisation.

Published: June 2022

Purpose: This research integrates the perceived risk theory and the technology acceptance model to identify the consumer’s perception of risk toward electronic banking services. The main purpose of this research is to see how consumers perceive risk and its dimensions in creating attitudes and continuing to use electronic banking services. Methodology: To assess and measure customer perception, a questionnaire was adapted and distributed at branches of banks in Prishtina, which distributed the questionnaire to their customers. The confirmatory factor analysis and the regression analysis were performed in this study. Results: From the data obtained we can conclude that, compared to the risk components, the perception of benefits has a greater impact on consumer decision-making when using electronic banking services. Conclusion: This research has some implications. In theoretical terms, the findings provide a detailed perspective on the impact of risk components and benefits on attitudes and intention to use e-banking services. Whereas on the practical level, it provides recommendations for managers of commercial banks in Kosovo to create strategies and mechanisms aiming to increase security levels and consequently maximize customer trust in e-banking services.

Abstract. The new concept of Open Spatial Data Infrastructures (Open SDIs) has emerged from an increased interest in open data initiatives together with national and international directives, such as the EU Open Data Directive (Directive (EU) 2019/1024), and the large investment of European public authorities in developing SDIs for sharing spatial data within public authorities. Open SDIs have the potential to boost reaching SDIs’ general aims and goals of facilitating the exchange and sharing of spatial data to support planning and decision-making by including public participation and increased openness in all aspects of SDIs, including Open SDI Education. The open SPatial data Infrastructure eDucation nEtwoRk (SPIDER) project aims to address Open SDI Education by particular emphasis on studying Active Learning and Teaching (ALT) methods for SDI education. This article provides a theoretical basis of ALT for SDI methodologies. We show in which way ALT practices were already implemented in SDI education at the Partner universities before the COVID-19 pandemic. We also describe how the pandemic functioned as a catalyst for implementing ALT practices to an online environment, and how students evaluated these practices. The outcomes of our research can serve as an inspiration for SDI education in other countries.
Understanding the Imperfection of 3D point Cloud and Semantic Segmentation algorithms for 3D Models of Indoor Environment
Authors: Cai Guoray , Pan Yimu
Published: June 2022

Abstract. Point clouds data provides new potentials for automated construction of more geometrically accurate and semantically rich 3D models for indoor environments. Recent advances in deep learning methods on point cloud semantic segmentation demonstrated impressive accuracy in labeling points of 3D surfaces with object classes. However, it remains challenging to reconstruct the shape of semantic objects from semantically-labeled 3D points, due to imperfection of such data and the under-determination of object construction algorithms. We have little empirical knowledge about how data imperfections affect the reconstruction of 3D indoor room objects. This paper contributes to understanding the nature of such imperfection of 3D point cloud data and semantic segmentation algorithms by analyzing the reconstructability of indoor room objects from semantically-labeled point cloud. 181 rooms from Stanford Large-Scale 3D Indoor Spaces Dataset (S3DIS) were used in our experiment. After generating semantic labels on point-clouds using PointNet++ segmentic segmentation algorithm, we use human coders to judge the reconstructability of indoor objects, following a qualitative coding scheme. Human exploration of object shape imperfection was assisted by a visual analytic tool in making their judgement. We found that high point-level accuracy achieved through semantic segmentation of point cloud data does not guarantee high object-level accuracy. The extent of this problem varies widely among different spatial settings and configurations. We discuss the significance of these findings on the choice of 3D reconstruction methods.
Modelling eye-level visibility of urban green space: Optimising city-wide point-based viewshed computations through prototyping
Authors: Brinkmann Sebastian T. , Kremer Dominik , Walker Blake Byron
Published: June 2022

Abstract. Studies from public and environmental health show strong indication of the importance of visible urban green space. However, current approaches for modelling viewshed based greenness visibility still have high computation costs. As a consequence, comparative studies of city-wide visible greenness, everyday mobility, and individual attention are still at the edge of feasibility. Known optimisations focus on reducing the computation time of single viewsheds. As point-based viewsheds are computed using geospatial data, current approaches seek to accelerate calculation using intelligent data structures or spatial indexes (at the cost of additional memory) or develop approximative heuristic solutions. In contrast, as we aim to process large numbers of viewsheds with fixed parameterisations, we use a prototyping approach preprocessing a single viewshed template to store common prefixes of consecutive lines of sight that can be applied to followup viewsheds by a simple offset operation. Our evaluation shows an average improvement of 34% over the benchmark algorithm (RFVS), with even stronger improvements for large viewsheds. We anticipate that these findings lay the groundwork for further optimisation of point-based viewshed computation, improving the feasibility of subsequent comparative studies in the field of public and environmental health.

Published: June 2022

Abstract. The Modifiable Areal Unit Problem or MAUP is frequently alluded to but rarely addressed directly. The MAUP posits that statistical distributions, relationships and trends can exhibit very different properties when the same data are aggregated or combined over different reporting units or scales. This paper explores a number of approaches for determining appropriate scales of spatial aggregation. It examines a travel survey, undertaken in Ha Noi, Vietnam, that captures attitudes towards a potential ban of motorised transport in the city centre. The data are rich, capturing travel destinations, purposes, modes and frequencies, as well as respondent demographics (age, occupation, housing etc) including home locations. The dataset is highly dimensional, with a large n (26339 records) and a large m (142 fields). When the raw individual level data are used to analyse the factors associated with travel ban attitudes, the resultant models are weak and inconclusive - the data are too noisy. Aggregating the data can overcome this, but this raises the question of appropriate aggregation scales. This paper demonstrates how aggregation scales can be evaluated using a range of different metrics related to spatial and non-spatial variances. In so doing it demonstrates how the MAUP can be directly addressed in analyses of spatial data.
Sonification of Spatial Data: An Online Audiovisual Cartographic Representation of Fire Incidents
Authors: Foteinou Aikaterini , Kokla Margarita , Tomai Eleni , Kavouras Marinos
Published: June 2022

Abstract. The possibilities of using sound in cartography have been formulated by numerous researchers. However, there are still no general guidelines for mapping data dimensions to auditory variables, while the decision of which spatial data dimension to represent by which sound variable is crucial. The method for embedding sound in maps is commonly known as "sonification"; the representation of data through sound. Many researchers use sonification to convey their data through the auditory channel as an alternative way to understand and represent our complicated world. With this in mind, we created an interactive web map that depicts the fire dynamics, adopting the sonification technique of parameter mapping; a sound variable was used to represent fire duration. For assessing the effectiveness of different sound variables for this map, an online survey was conducted. The main finding is that to represent spatial data through sound, participatory approaches can highlight the most effective cross-modal correspondence.
Enabling Collaborative Cybercartography with MapBlender
Authors: Hogräfer Marius , Grønbæk Jens Emil , Puschmann Jana , Krog Knudsen Sebastian , Schulz Hans-Jörg
Published: June 2022

Abstract. One of the challenges that GIS users in diverse, distributed teams face these days is being able to efficiently collaborate, both across workspaces and tools. To that end, we present MapBlender, a cybercartographic application that fosters geocollaboration by adapting a collaboration-first approach, placing users and their GIS tools on equal footing. MapBlender allows all connected users to share video feeds of their GIS tools and webcams, which can then be freely rearranged and re-sized, adopting simple and familiar interaction techniques from modern window managers. In addition, the rendering and translucency of these feeds can be adjusted, allowing users to align and analyze information across tools. We demonstrate the utility of MapBlender in a hybrid teaching scenario, wherein a representative of a software company uses our application to instruct co-located and remote learners from another company on the features of their GIS tool. MapBlender is publicly available under open source licenses and runs in the browser, with no local installation necessary. Thus, with MapBlender in place, one of our goals is to promote an HCI perspective on future work in geocollaboration.
Classifying Urban Green Spaces using a combined Sentinel-2 and Random Forest approach
Authors: Ismayilova Irada , Timpf Sabine
Published: June 2022

Abstract. Environmental and human benefits of Urban Green Spaces (UGSs) have been known for a long time. However, the definition of a reasonable greening strategy still remains challenging due to the lack of sufficient baseline information as well as a lack of consensus what constitutes a UGS. Therefore, accurate identification of the existing green spaces in cities is crucial for developing UGS inventories for urban planning and resource management activities. In this paper we explore the potential of freely available highest resolution multi-spectral remote sensing imagery to identify large homogeneous as well small heterogeneous UGSs. The approach of using a Random Forest classification on Sentinel-2 imagery is shown to be useful to identify various UGSs with a 97 % accuracy. Freely available data and a relatively straightforward implementation of the proposed approach makes it a valuable tool for decision and policy makers.
Six GIScience Ideas That Must Die
Authors: Janowicz Krzysztof , Zhu Rui , Verstegen Judith , McKenzie Grant , Martins Bruno , Cai Ling
Published: June 2022

Abstract. In 2015, John Brockman edited a volume of chapters contributed by leading thinkers from various domains discussing common scientific ideas hindering further scientific progress. While starting with the provocative slogan of This Idea Must Die, the book’s chapters and their authors (for most parts) do not argue that those existing – often foundational scientific theories from various domains – are false, but instead that their widespread, and often unquestioned, utilization has started to hinder the evolution of new theories. Through this work, we would like to foster a similar discussion in our community, by suggesting six ideas in GIScience/geoinformatics that may benefit from retiring to make room for new perspectives. Our suggestions are somewhat controversial, and readers are encouraged to keep an open mind.

Introdução: Um dos obstáculos enfrentados pelo deficiente visual é o descaso de parte da sociedade às limitações cotidianas de tal condição. Não obstante a precária participação da sociedade, os profissionais da educação e da saúde deveriam ser integrados ativamente no auxílio dessas pessoas para melhorar a sua percepção em relação à sua condição bucal. Objetivos: Este estudo revisou a literatura brasileira dos últimos 20 anos, em busca de artigos que relatem a percepção dos deficientes visuais em relação à sua saúde bucal. Método: A revisão integrativa da literatura foi o método adotado, com análise quantitativa, exploratória e descritiva dos dados. O modelo de busca aplicado foi "pessoas com deficiência visual" e "saúde bucal" e "percepção" nas bases de dados Google Acadêmico, Literatura latino-americana e do Caribe em Ciências da Saúde (LILACS) e Biblioteca Virtual em Saúde (BVS), da Biblioteca Eletrônica Científica Online (SciELO), com consultas feitas em maio de 2021. Resultados: Dezoito registros foram encontrados. Seis registros foram excluídos e doze seguiram para análise descritiva. Destes, oito artigos foram excluídos e quatro seguiram para síntese qualitativa. Conclusão: A percepção dos deficientes visuais foi mensurada por diversos questionários e sua saúde bucal é percebida como satisfatória. Necessitam de ações voltadas à prevenção e promoção, com materiais didáticos para educação em saúde bucal, orientação de higienização e dieta alimentar. Defendem novas formas de ensino, com mais efetividade na motivação e treinamento da habilidade psicomotora para a realização da higiene bucal. A revisão evidenciou a escassez de artigos científicos publicados na literatura brasileira.
Energy Consumption and Economic Growth in the European Union: A Causality Analysis
Authors: GRODZICKI Tomasz , JANKIEWICZ Mateusz
Published: June 2022

Energy sector is one of the most important matters in the economic policies of the European Union since it has a significant impact on the quality of life and economic growth. The aim of this paper is to examine the causal relationship between energy consumption and economic growth in the European Union, based on the data from the period of 1960–2015. Using a Granger causality test, empirical results clearly indicate that energy consumption contributed to economic growth in the European Union. More precisely, an increase in energy consumption led to an increase in GDP per capita growth in the next period. This relationship is often called a growth hypothesis, which implies that energy consumption can stimulate economic growth. This research also analyzed the opposite relationship: the impact of economic growth on the change in energy consumption, which is called conservation hypothesis. However, this analysis has not proved such an impact in the considered period. The vector autoregression model (VAR) was used in the dependency analysis. In addition, an analysis of the impulse response shows the behavior of both processes as a result of a unitary, unexpected change in one of them.
Regional Specialization in the Colombian Manufacturing Industry: A New Economic Geography Approach
Authors: GÓMEZ Helmuth Yesid Arias , ANTOSOVA Gabriela
Published: June 2022

The New Trade Theory(NTT) and New Economic Geography (NEG) explain production specialization of countries or regions by benefits stemming from economies of scale, which are available even when trade partners are in similar economic conditions and with even resource endowments. Conversely, the traditional trade theory relies on comparative advantages that emerge from differences in technology and costs. Recently, some authors propose to combine both theories. After discussing the theoretical background, the paper presents an empirical analysis based on panel data which tries to explain the branch and regional structure of manufacturing industry in Colombia. The results confirm the importance of natural advantage, resource endowments, transport costs and the access to national and international industrial circuits in shaping the spatial structure of manufacturing and its development trends.

Jako miary tej pozycji przyjęto wskaźniki stóp bezrobocia i zatrudnienia, przepływów osób między zasobami bezrobotnych, zatrudnionych i biernych zawodowo oraz oszacowania parametrów wielomianowego modelu logitowego, wskazujące na relatywne prawdopodobieństwa odpływów osób z bezrobocia i zatrudnienia. Analizy statystyczne oparto na danych agregatowych i jednostkowych BAEL z lat 2009–2018, które rozpatrywano dla dwóch podokresów: podokresu osłabienia koniunktury w latach 2009–2013 i podokresu korzystnej koniunktury w latach 2014–2018. Z analizy wynika, po pierwsze, że relatywnie najgorsze pozycje na rynku pracy zajmowały grupy kobiet, osoby w wieku 15–24 lat oraz osoby z wykształceniem gimnazjalnym i podstawowym, co uwidoczniło się w obu odmiennych stanach koniunktury, natomiast osoby mieszkające w mieście zajmowały gorszą pozycję na rynku pracy od mieszkańców wsi w latach niekorzystnej koniunktury 2009–2013, ale lepszą pozycję w okresie korzystnej koniunktury lat 2014–2018. Po drugie, większą zmianę pozycji zajmowanej na rynku pracy przy poprawie koniunktury zaobserwowano w grupach kobiet, osób starszych, z wykształceniem wyższym i średnim ogólnokształcącym oraz osób mieszkających w mieście. Istotny wpływ na te tendencje miały rozwiązania instytucjonalne z zakresu polityki rodzinnej i systemów emerytalnych, a także zróżnicowana mobilność siły roboczej w badanych grupach ludności.

Despite administration of various drug treatment regimens leaves a large proportion of patients with resistant hyperten- sion with uncontrolled blood pressure values, who are at increased risk for cardiovascular and renal complications. Recognition of the major role of the sympathetic nervous system in the pathogenesis of hypertension has led to the development of new minimally invasive methods, which reduce the activity of the sympathetic nervous system at the peripheral renal level, resulting in reduced blood pressure. One such treatment is renal artery denervation - an innovative method devised 10 years ago that involves disrupting afferent and efferent renal sympathetic fibers by applying radiofrequency energy.In this way, we aimed to conduct an open-label clinical study that will assess the effectiveness of blocking the sympathetic nervous system through various therapeutic regimens on blood pressure variability and diurnal profile in patients with resistant hypertension. The data obtained demonstrated the antihypertensive effectiveness of both pharmacological and interventional treatment, but renal denervation having a much higher impact.

Despite the fact that women have lower incidence of non-ST-elevation myocardial infarction (NSTEMI) compared with men, they have a higher mortality, attributed to the impact of the age, higher burden of comorbidities, atypical symptoms and possible differences in the diagnosis and treatment of NSTEMI. Based on this, we aimed to evaluate the sex differences in the clinical presentation, management and major adverse cardiovascular events (MACE) of patients presenting with NSTEMI in the Republic of Moldova. Data were collected from the observational studies: retrospective (2019) and prospective (2020-2021), conducted in 3 PCI centers in Moldova, which included 351 consecutive patients with the clinical diagnosis NSTEMI. The data obtained were processed by descriptive statistical methods, using the t-test, the Pearson χ² test and the p-value. After analyzing the obtained results, we concluded that women had a lower incidence of NSTEMI, but had a higher rate of risk factors and comorbidities, compared to men, they presented more frequently atypical symptoms and more often had myocardial infarction with non-obstructive coronary arteries (MINOCA). At the same time, several gaps in the management of women with NSTEMI in the Republic of Moldova were highlighted. MACE proved to be similar at both sexes, but with a higher mortality at women. These data guide us to the need of a comprehensive approach of women with NSTEMI, taking into account the gender particularities in the clinical presentation and management of the disease.
The association of diabetes mellitus and acute myocardial infarction in the development of atrial fibrillation
Authors:   Institute of Cardiology, the Republic of Moldova, Chiriliuc Nadejda
Published: June 2022

Diabetes mellitus is one of the most common chronic medical conditions and is an independent risk factor for both: acute myocardial infarction and the development of atrial fibrillation. Both, diabetes mellitus and acute myocardial infarction promote the development of a proinflammatory status and oxidative stress in the atrial tissue, these being a substrate of the development of atrial fibrosis, and consequently of atrial fibrillation.
Predictors of antihypertensive efficiency of renal denervation. (Literature review)

Hypertension remains the leading cause of preventable cardiovascular disease and the main problem of overall mortality globally and also in Europe. Despite pharmacological advances, the control rates of blood pressure remain low worldwide and are far from being satisfactory in Europe. The renal sympathetic denervation is an innovative method, conceived 10 years ago, that involves the disruption of afferent and efferent renal sympathetic fibers by applying radiofrequency energy, thus reducing sympathetic activity and at the same time decreasing the blood pressure. Therefore, renal denervation expands the therapeutic options as being the first goal of hypertension treatment, which means the effective reduction of blood pressure values by achieving therapeutic targets.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) involves clinical documentation of an AMI and demonstration of the absence of anatomically significant stenosis (<50% of lumen diameter) on coronary angiography. As it has a heterogeneity of etiologic factors, the mechanisms of MINOCA as well as the performance of diagnostic algorithms and therapeutic strategies have been extensively studied. The importance of personal management strategy for each patient is presented alongside stratification of risks of recurrent cardiovascular events. This statement provides a general view on MINOCA based on the newest published data.

Obesity and overweight among children and adolescents are accepted worldwide as a chronic multifactorial disorder, with a significant increase in annual prevalence. Abdominal obesity in association with other metabolic risk factors such as hypertension, high cholesterol and triglycerides, as well as low HDL cholesterol are grouped into a syndrome defined as„Reaven syndrome” or „metabolic syndrome”. MetS is often associated with cardiovascular and diabetic risk in children and also with liver damage. Current strategies addressed for the treatment of obesity and metabolic syndrome in children include adequate nutrition, combating sedentary lifestyle, drug therapy, which are used alone, or in combination. These measures are taken to reduce overweight, dyslipidemia, high blood pressure and insulin resistance in children and adolescents.
