Abstract:

Purpose The purpose of this paper is to explore the “dark nuances” of social media by identifying moral disengagement (MD) mechanisms and hostile emotions in people discussing the hosting of immigrants and examining the relationship between MD mechanisms and hostile emotions expressed online (annoyance, irritation and contempt). Design/methodology/approach The method was based on a psycho-lexicographical approach that analysed the in vivo real words, adopting a quanti-qualitative point of view. The investigation started from the case of a Facebook post in support of immigrants after a serious shipwreck causing the death of more than 700 would-be migrants. More than 10,000 comments were codified. For the comments against the hosting of such immigrants, the authors followed a codebook aimed at identifying MD mechanisms and hostile emotions. Findings The main findings show an interplay between different hostile negative emotions and online MD mechanisms. The greater the intensity of hostile emotions, the more the locus of disengagement moves from the unethical individual’s behaviour – for example, offering moral justifications – to the target recipient of such behaviour – for example, blaming or dehumanising. Practical implications The study could be applicable in designing and developing algorithms and technological tools aimed at preventive interventions to promote moral awareness and emotional regulation in online settings. Social implications The study may be a useful contribution to understanding unethical orientation by identifying areas where education can intervene in reducing harmful behavioural tendencies. Originality/value This study takes together expressed hostile emotions and MD mechanisms by means of the analysis of real words in vivo through social media discussions.

Abstract:

The Commonwealth Games Federation recently awarded the hosting of the 2022 Games to Durban, South Africa. This will be the first time the Games are hosted in the African continent. The paper looks into whether tangible benefits for hosting mega-events are less or more important than intangible benefits. In investigating this issue, the paper takes a political geography theoretical stance for its ability to provide normative ideological content for explaining intangible and tangible values for hosting Commonwealth Games. The paper looks at pros and cons for investing in mega-event infrastructure and also looks at the cost of hosting the Games for cities. The 2010 Commonwealth Games in Delhi budgeted $240 million for the entire Games, but the actual costs after the Games were found to be $1.7 billion. Similarly, in 2014 Glasgow, the cost of the Games was calculated at £575 million ($690 million). The paper looks at whether South Africa as the 2022 Commonwealth Games host can afford the games. It also considers the impact of the Games on national identity, national pride and patriotism here identified as novelty values that preserve social cohesion, a social attribute that has to be in place to build a robust economy. The paper concludes by noting that the success of the Games will depend on deliberate investment in catalytic facilities in areas that will be sustained post event. The amount of novelty value generated out of the Commonwealth Games will depend on how successful the Games are and on how the communities are able to interact with the facilities post event.

Abstract:

We explore conditions under which a multiproduct firm can profitably turn itself into a platform by “hosting rivals,” that is, by inviting rivals to sell products or services on top of its core product. Hosting eliminates the additional shopping costs to consumers of buying a specialist rival’s competing version of the multiproduct firm’s noncore product. On the one hand, this makes it easier for the rival to compete on the noncore product. On the other hand, hosting turns the rival from a pure competitor into a complementor: the value added by its product now helps raise consumer demand for the multiproduct firm’s core product. As a result, hosting can be both unilaterally profitable for the multiproduct firm and jointly profitable for both firms. This paper was accepted by Joshua Gans, business strategy.

Abstract:

Purpose The purpose of this paper is to explore how a legacy of event hosting competencies from one event can contribute to advancing the overall hosting capacity of a nation for future events. More specifically, the project focuses on determining the event hosting capacity legacies from the Men’s Under-20 2007 Fédération Internationale de Football Association (FIFA) event in Canada and how they contributed toward winning the rights for the Women’s FIFA World Cup 2015 event. Design/methodology/approach A qualitative case study design focusing on FIFA events held in Canada in 2007 and 2015 was used. Findings Four broad event hosting capacity legacies from the U-20 2007 event that potentially impacted Canada’s ability to secure the WWC 2015 were identified. These legacies included: exemplifying success, advancement of hosting concepts, staff and leadership experience and development and enhancement of sporting infrastructure. Research limitations/implications The findings formed the basis of a discussion on the increasing formalization of event organizing committees, the need to consider collective (i.e. multiple events) legacies in the development of hosting strategies as well as the importance of developing the trust of the local community to support future sport event bids and hosting. Originality/value The originality and value of this research paper lies in its use of empirical case study findings to illustrate the potential for hosting capacity legacies of sporting events as well as the level and type of event under investigation (i.e. large-scale, football/soccer).

Abstract:

This paper presents a stochastic approach to single-phase and three-phase EV charge hosting capacity for distribution networks. The method includes the two types of uncertainties, aleatory and epistemic, and is developed from an equivalent method that was applied to solar PV hosting capacity estimation. The method is applied to two existing low-voltage networks in Northern Sweden, with six and 83 customers. The lowest background voltage and highest consumption per customer are obtained from measurements. It is shown that both have a big impact on the hosting capacity. The hosting capacity also depends strongly on the charging size, within the range of charging size expected in the near future. The large range in hosting capacity found from this study—between 0% and 100% of customers can simultaneously charge their EV car—means that such hosting capacity studies are needed for each individual distribution network. The highest hosting capacity for the illustrative distribution networks was obtained for the 3.7 kW single-phase and 11 kW three-phase EV charging power.

Abstract:

Abstract The present study aims to help better understand the cognitive and affective processes at work in ‘moral struggles’ concerning discussions about hosting immigrants. In particular, it will focus on the prosocial aspect of the debate on hosting of immigrants since previous studies have stressed mainly its racist nature. To this end, a total of 12,583 comments were extracted from the Facebook page of an Italian singer, divided into prosocial and proself stances, and analysed by developing a specific coding based on the theory of helping behaviour in emergency (Darley and Latané 1968) and the theory of moral agency (Bandura 1991). Prosocial processes were defined on the basis of the following ‘loci’: recipients, behaviour, consequences and agency. In parallel the comments were analysed by emotional coding to identify the levels of expressed anger. The results showed a wide variety of prosocial stances associated with these loci in online arguments within real sentences. Prosocial commenters can use words as weapons toward proself commenters to win their ‘crusade’ when they are flamed, and they are ‘cold’ when they focus on recipient and consequences. Finally, results suggested that a dialogue between prosocial and proself positions can occur in the presence of a moderate level of anger.

Abstract: Data hosting on cloud decreases cost of IT maintenance and data reliability get enhance. Nowadays, customers can store their data on single cloud, which has some drawbacks. First is vendor lock in problem and second is security on cloud. The solution to this problem is to store the data on different cloud server without redundancy using encryption algorithm. Customers do not want to lose their sensitive data on cloud. Another issue of cloud computing is data thievery should be overcome to supply higher service. Multi-cloud environment has ability to scale back security risks. To avoid security risk we offer framework. Keywords: Cloud computing, cloud storage, data hosting, data intrusion, multi-cloud, single cloud.

Abstract:

Previous research demonstrates that refugee populations can threaten the security of receiving countries. This study, in contrast, seeks to examine the physical security challenges refugees face in host states. It utilizes a new, geographically referenced data set on subcountry refugee demographics to test the hypothesis that locations home to larger refugee populations are more likely to experience one-sided attacks by conflict actors. Results demonstrate that refugee accommodation is a significant predictor of one-sided violence in Africa. In particular, combatants commit significantly more acts of violence against civilians in locations home to larger numbers of self-settled refugees compared to other locations. These findings suggest that scholars and practitioners account for possible dangers presented by refugee flows and threats to refugees simultaneously.

Abstract:

We discuss the inhomogeneous pion condensed phase within the framework of chiral perturbation theory. We show how the general expression of the condensate can be obtained solving three coupled differential equations, expressing how the pion fields are modulated in space. Upon using some simplifying assumptions, we determine an analytic solution in (3+1)-dimensions. The obtained inhomogeneous condensate is characterized by a non-vanishing topological charge, which can be identified with the baryonic number. In this way, we obtain an inhomogeneous system of pions hosting an arbitrary number of baryons at fixed position in space.

Abstract:

The APPLICATION PLACEMENT PROBLEM (APP, for short) arises in hosting platforms: clusters of servers that are used for hosting large, distributed applications such as Internet services. Hosting platforms imply a business relationship between an entity called the platform provider and a number of entities called the application providers. The latter pay the former for the resources on the hosting platform, in return for which, the former provides guarantees on resource availability for the applications. This implies that a hosting platform should host only applications for which it has sufficient resources. The objective of the APP is to maximize the number of applications that can be hosted on the platform while satisfying their resource requirements. The complexity of the APP is studied here, with the following results. The general APP is NP-hard; indeed, even restricted versions of the APP may not admit polynomial-time approximation schemes. However, several significant variants of the online version of the APP admit efficient approximation algorithms.

Abstract:

This paper outlines a methodology to determine the amount of renewable energy that can be accommodated in a power system before adverse impacts such as over-voltage, over-loading and system instability occur. This value is commonly known as hosting capacity. This paper identifies when the transmission network local hosting capacity might be limited because of static and dynamic network limits. Thus, the proposed methodology can effectively be used in assessing new interconnection requests and provides an estimation of how much and where the new renewable generation can be located such that network upgrades are minimized. The proposed approach was developed as one of the components of the AUSTEn project, which was a three-year project to map Australia’s tidal energy resource in detail and to assess its economic feasibility and ability to contribute to the country’s energy needs. In order to demonstrate the effectiveness of the proposed approach, two wide area networks were developed in DIgSILENT PowerFactory based on actual Australian network data near two promising tidal resource sites. Then, the proposed approach was used to assess the local tidal hosting capacity. In addition, a complementary local hosting capacity analysis is provided to show the importance of future network upgrades on the locational hosting capaity.

Abstract:

According to the global de-carbonization trends, renewable energy integration has become an increasingly important issue in power systems. To achieve 100% renewable energy integration and operate a system with these resources, it is necessary to appropriately evaluate the system hosting capability and prepare appropriate planning and operation strategies using the evaluation result. So far, these interests have focused particularly on distribution-level systems. However, although the hosting limit in transmission-level systems requires further consideration, previous study is limited. This study introduces the constraints on the transmission-level hosting limit. In addition, a stochastic estimation of the hosting limit methodology in the transmission system and the use of a high voltage direct current system to improve hosting capacity are proposed and evaluated. Moreover, these methodology-based simulations are conducted using possible scenarios on the IEEE 39 bus system with some constraints, and the simulation results are presented herein. The results showed that the HVDC location selection and operation using the proposed method and optimization technique is appropriate. The strategy can be used to integrate more renewable energy. Furthermore, the proposed methodology can be applied to renewable energy integration scenario establishing a plan.

Abstract:

Purpose – Singapore hosted the inaugural Youth Olympic Games (YOG) in 2010. Prior studies have shown that a country hosting a major sports event can raise the level of national pride among its citizens. The purpose of this paper is to examine the change in national pride among spectators and non-spectators following the hosting of the YOG. Design/methodology/approach – A longitudinal research design was employed in this study. Surveys using the General National Pride Scale to measure the level of national pride were conducted two months before and after the YOG. Findings – Using paired t-tests, the results showed that there was a significant increase in the level of national pride among non-spectators. Research limitations/implications – The research concurs with earlier research that hosting a major sports event can increase the level of national pride in the population. Practical implications – From an application standpoint, this research suggests that in planning major sports events, the government should recognise that such events can increase the level of national pride even among those who have expressed no interest in the sports events. Social implications – National pride can be fostered through the hosting of major sports events. Originality/value – This study demonstrates that in hosting a major sports event, there is an increase in national pride even among non-spectators and those who have no interest in the event.

Abstract:

AbstractThe NASA Star and Exoplanet Database (NStED) is a general purpose stellar archive with the aim of providing support for NASA's planet finding and characterization goals, stellar astrophysics, and the planning of NASA and other space missions. There are two principal components of NStED: a database of (currently) 140,000 nearby stars and exoplanet-hosting stars, and an archive dedicated to high precision photometric surveys for transiting exoplanets. We present a summary of the NStED stellar database, functionality, tools, and user interface. NStED currently serves the following kinds of data for 140,000 stars (where available): coordinates, multiplicity, proper motion, parallax, spectral type, multiband photometry, radial velocity, metallicity, chromospheric and coronal activity index, and rotation velocity/period. Furthermore, the following derived quantities are given wherever possible: distance, effective temperature, mass, radius, luminosity, space motions, and physical/angular dimensions of habitable zone. Queries to NStED can be made using constraints on any combination of the above parameters. In addition, NStED provides tools to derive specific inferred quantities for the stars in the database, cross-referenced with available extra-solar planetary data for those host stars. NStED can be accessed at http://nsted.ipac.caltech.edu.

Abstract:

Most of the world's displaced people are hosted in low-income countries. Focusing on evidence from poor countries, we review the literature on the economic consequences of hosting refugees or internally displaced people. In the short run, violence, environmental degradation, and disease propagation are major risks to the host populations. In the long run, infrastructure, trade, and labor markets are key channels that determine the impacts on host communities. These impacts can be positive or negative and often unequally distributed among different hosts. We discuss policy options for building resilience in the light of this evidence. Investments in road infrastructure and deepening trade with refugees’ countries of origin are strategies worth exploring for enhancing resilience and transitioning from humanitarian assistance toward development. Finally, we identify key knowledge gaps in this literature and formulate a research agenda for the near future.

Abstract:

Purpose – Cities all over the world rebrand themselves in order to refresh their image and attract/continue attracting tourists, industry or whichever group they hope to engage. Cities have tended to rebrand themselves based on varied social events and festivals such as fashion (Milan), food and beverages (Munich), folklore dancing (Rio de Janeiro), film (Cannes) and many more. The most powerful platform for rebranding a city is hosting the Olympic Games. Despite the fact that many city planners and decision-makers tend to perceive the Olympic Games as the highest yielding investment for reinforcing a city image, in the last three decades many host cities have lost millions of dollars, with this rare opportunity to leverage their city's image becoming one big fiasco. The aim of this paper is to present the key rules for making hosting the Olympic Games a very profitable business, in terms of reinforcing the city image. Design/methodology/approach – Since some host cities are more established in economic terms and some are less, two different approaches (the “Barcelona model” and the “London model”) are discussed. Findings – The Barcelona model shows how a city can leverage its image, based on the Olympic Games, to become more familiar to millions of potential tourists, and the London model shows how an entire country can also profit from the fact that its capital is hosting the Olympic Games. Originality/value – The Barcelona model shows how a city can leverage its image, based on the Olympic Games, to become more familiar to millions of potential tourists, and the London model shows how an entire country can also profit from the fact that its capital is hosting the Olympic Games.

Abstract:

Intermittent power generated from renewable distributed energy resource (DER) can create voltage stability problems in the system during peak power production in the low demand period. Thus, the existing standard for operation and management of the distribution system limits the penetration level of the DER and the amount of load in a power system. In this standard, the hosting capacity of the DER is limited to each feeder at a level where the voltage problem does not occur. South Korea applied this standard, thereby making it hard to achieve its DER target. However, by analyzing the voltage stability of an integrated system, the hosting capacity of DER can be increased. Therefore, in this study, the maximum hosting capacity of DER is determined by analyzing an integrated transmission and distribution system. Moreover, the fast voltage stability index (FVSI) is used to verify the determined hosting capacity of DER. For this, the existing interconnection standard of DER at a feeder, distribution system, and transmission system level is investigated. Subsequently, a Monte Carlo simulation is performed to determine the maximum penetration of the DER at a feeder level, while varying the load according to the standard test system in South Korea. The actual load generation profile is used to simulate system conditions in order to determine the maximum DER hosting capacity.

Abstract:

Uncertainties associated with the loads and the output power of distributed generations create challenges in quantifying the integration limits of distributed generations in distribution networks, i.e., hosting capacity. To address this, we propose a distributionally robust optimization-based method to determine the hosting capacity considering the voltage rise, thermal capacity of the feeders and short circuit level constraints. In the proposed method, the uncertain variables are modeled as stochastic variables following ambiguous distributions defined based on the historical data. The distributionally robust optimization model guarantees that the probability of the constraint violation does not exceed a given risk level, which can control robustness of the solution. To solve the distributionally robust optimization model of the hosting capacity, we reformulated it as a joint chance constrained problem, which is solved using the sample average approximation technique. To demonstrate the efficacy of the proposed method, a modified IEEE 33-bus distribution system is used as the test-bed. Simulation results demonstrate how the sample size of historical data affects the hosting capacity. Furthermore, using the proposed method, the impact of electric vehicles aggregated demand and charging stations are investigated on the hosting capacity of different distributed generation technologies.

Abstract:

This paper focuses on the impact of hosting of IIHF World Championship on the local hotel market using the case of Prague (IIHF World Championship 2015) and Bratislava (IIHF World Championship 2011). Many previous studies were focused on the impact of hosting mega sports and cultural events on destination perception and visit rate during and after the event, perception of hosting these events by residents or the effect on the local economy. Using unique daily empirical data collected from 95 Prague hotels and 25 Bratislava hotels, key findings of this study show lack of long-run positive impact but a high short-run (immediate) effect. In the case of Prague, the main increase of market performance can be identified during the final stage of the tournament, mainly in selling room rates; for Bratislava, the significant effect was determined during the whole tournament, and the entire market never reached the same level of performance. The study shows the need to examine these effects further, emphasizing more variables like seasonality and market segmentation, revenue management, and destination management.

Abstract:

In recent years, hybrid wind-photovoltaic (PV) systems are flourishing due to their advantages in the utilization of renewable energy. However, the accurate assessment of the maximum integration of hybrid renewable generation is problematic because of the complex uncertainties of source and demand. To address this issue, we develop a stochastic framework for the quantification of hybrid energy hosting capacity. In the proposed framework, historical data sets are adopted to represent the stochastic nature of production and demand. Moreover, extreme combinations of production and demand are introduced to avoid multiple load flow calculations. The proposed framework is conducted in the IEEE 33-bus system to evaluate both single and hybrid energy hosting capacity. The results demonstrate that the stochastic framework can provide accurate evaluations of hosting capacity while significantly reducing the computational burden. This study provides a comprehensive understanding of hybrid wind-PV hosting capacity and verifies the excellent performance of the hybrid energy system in facilitating integration and energy utilization.

Abstract:

The introduction of a complex electrical vehicle charging (EVC) infrastructure consisting of an electrical vehicle (EV) charger and renewable energy source (RES) in the distribution system has been required as an important countermeasure for global environmental issues. However, the problems for hosting capacity and power stability of the distribution feeder can be caused by the penetration of lager scaled RES and EVC infrastructure. Further, it is required for the efficient operation method to prevent congestion and to ensure hosting capacity for the distribution feeder due to the increase of variable RES and EVC infrastructure in the distribution systems. In order to solve these problems, it is necessary to develop a technology which is capable of stably introducing an EVC infrastructure without reinforcing the existing distribution system. Therefore, to maintain the existing hosting capacity of distribution feeder and allowable limits, this paper presents a virtual power line (VPL) operation method using Energy Storage System (ESS) based on the power and voltage stabilization control to ensure hosting capacity of the EVS infrastructure. The proposed operation method is determined by optimal power compensation rate (PCR) and voltage compensation rate (VCR). Specifically, ESS for VPL is controlled according to the charging and discharging mode is operated according to the comparison value of the PCR and VCR. From the test results, it is verified that hosting capacity of the distribution system can be maintained using the proposed control method of ESS for VPL operation.

Abstract:

There has been an increasing trend of integrating photovoltaic power plants (PVs). One of the important challenges for distribution system operators is to evaluate the total installed power of a PV that a particular network can host (or PV hosting capacity) while keeping voltage and element constraints within required limits. The major drawback of the existing methods for calculating PV hosting capacity is that they use the same installed power of the PV systems for all simulated PVs, as these methods do not use external data sources about building roofs. As a consequence, this has a significant impact on the final accuracy of the results. This paper presents a probabilistic methodology for calculating the PV hosting capacity in low voltage (LV) networks. The main contribution of this paper is the improved modeling of PV generation using actual building roof data when calculating the PV hosting capacity, as every building is treated according to its actual solar potential. Monte Carlo simulations with incorporated stochastic consumption and PV generation models are utilized for load flow calculations of the actual LV network. The simulation results presented in this paper prove that the proposed methodology increases the accuracy of the final PV hosting capacity calculations.

Abstract:

Special events, in general, and sports events, in particular, are a major focus and revenue generator for cities that host these events. They are time specific, and they can have a variety of short- or long-term, positive or negative impacts, which contribute to both beneficial or harmful outcomes. If prolonged over time, these outcomes have been called "legacies." This study sought to explore key stakeholders' perspectives on the attributes needed to host large-scale sports events. The research concentrated on identifying the main factors that attract large-scale sports events to specific municipalities, motivations to sponsor these events, and the main challenges faced by official agencies during events. The data were collected from 22 participants in a focus group meeting including three main types of stakeholders: event organizers, event sponsors, and official entities. The interview transcripts were processed using mixed-content analysis methods. The results revealed that the main themes mentioned by event organizers are media coverage, sports infrastructure, sponsor brands, discipline in sports, event organization, event and city security, motivation, capacity (e. g., accommodations), stakeholder commitment, residents, and territorial impacts. Sponsors are usually large well-known firms, and discussions about them covered the following themes: event–sponsor fit, sponsorship returns, mega-event territorial marketing, brand strategy, and sponsorship competition. The main themes mentioned by official entities are accessibility, events that sell cities, destination visibility, security, protection of athletes and the public, hospitals, residents, changes, and territory. This study's findings contribute to the existing literature by focusing on the specific case of largescale sports events and examining three main event stakeholders' perspectives. Managerial implications are also discussed.

Abstract:

Purpose As library budgets continue to constrict, librarians will need to become more familiar with comparing database host platforms. This paper aims to compare Inspec on Elsevier’s Engineering Village (EV) and Clarivate’s Web of Science (WOS) from a novice user experience. The main objectives are to identify some R1 institutions that subscribe to Inspec and highlight some of the key differences between the two platforms. Design/methodology/approach Information on Inspec was gathered from various sources such as the home website, IET, and the host platform websites of Elsevier and Clarivate Analytics. Additional evidence was also collected from brochures and guides to help illustrate some of the main features and differences that novice users would be familiar with. Findings Most institutions subscribe to Inspec via the EV platform. Results from the study conclude that EV was the choice over WOS for hosting Inspec owing to a more user-friendly interface, potential lower cost and faster platform updates in response to meeting user needs. Research limitations/implications As database platforms change over time, feature areas such as content, interface and features remain important for information professionals and librarians to stay current with those changes. Also, this work can help librarians with understanding the planning and developing of a process for comparing identical or similar databases on different platforms. Originality/value Much of the literature focuses on the unfamiliar details and not so much on the novice user. This paper provides a unique perspective in how a novice user would prefer the attributes of one host platform over the other. Additionally, the same review criteria can be applied in other subjects and disciplines.

Abstract:

Recreational sporting events are big business and cities throughout the United States are competing fiercely to host events (Saayman, & Saayman, & du Plessis, 2005). March (1984) suggested that the reason why smaller sporting events have received relatively little attention is because it is assumed that they are economically less significant. The purpose of this study was to estimate the economic impact of hosting a club sport national tournament on a midsize community. The current study estimates the economic impact of hosting the American Collegiate Hockey Association (ACHA) Division II National Championship. The survey consisted of 105 questionnaires that were completed during the three day tournament of which all 105 were used. The findings of the survey indicated that hosting a national tournament can have a positive effect on the local economy. It was estimated that nearly $2 million of new money may have been injected into the community of Fort Collins, Colorado. This research provides midsize cities with information to justify hosting one-time events and working favorably with the community university.

Abstract:

Public referenda have recently put an end to the ambitions of several cities to host the Olympic Games. The outcome of referenda depends on two major decisions: a content decision whether to support hosting the Olympics and a turnout decision whether or not to cast a vote. Unlike the content decision, the turnout decision has received little attention in sports economics, even though it can distort the outcome of a referendum, lead to a misrepresentation of minorities, and reduce the acceptance of referendum results. We therefore examine the determinants of turnout at Olympic referenda using a population-representative data set from 12 democratic countries. Our findings suggest a nonlinear and robust relationship between individual support and voter turnout.

Abstract:

ABSTRACT. Interest in global health training experiences among trainees from higher income countries has grown. The Working Group on Ethics Guidelines for Global Health Training (WEIGHT) clarified best practices in 2010 based on expert consensus. These guidelines address both balancing priorities in international partnerships and local sustainability concerns related to short-term experiences. However, the guidelines can be difficult to implement in actual practice. Because our organization predated the availability of these consensus guidelines, we reviewed our current set of practices for hosting service–learning programs at our rural Ugandan clinic for adherence to the WEIGHT guidelines. The discrete activities and standardized processes developed over 10 years of hosting experiences were grouped into broader hosting categories, with consensus among the hosting and sending volunteer coordinators of our non-governmental organization partnership. These practices were then mapped to the WEIGHT guidelines. We found our implementation strategies map these guidelines into a clear checklist of actions that can be used by coordinators involved in global health training programs. We include some of the historical reasons that led to our current processes, which may help other partnerships identify similar practice gaps. We anticipate that this action-oriented checklist with historical context will help accomplish the difficult implementation of best practices in global health training collaborations.

Abstract:

Ontologies are increasingly being developed on web-based repository hosting platforms such as GitHub. Accordingly, there is a demand for ontology editors which can be easily connected to the hosted repositories. TurtleEditor is a web-based RDF editor that provides this capability and supports the distributed development of ontologies on repository hosting platforms. It offers features such as syntax checking, syntax highlighting, and auto completion, along with a SPARQL endpoint to query the ontology. Furthermore, TurtleEditor integrates a visual editing view that allows for the graphical manipulation of the RDF graph and includes some basic clustering functionality. The text and graph views are constantly synchronized so that all changes to the ontology are immediately propagated and the views are updated accordingly. The results of a user study and performance tests show that TurtleEditor can indeed be effectively used to support the distributed development of ontologies on repository hosting platforms.

Abstract:

The increasing penetration of Photovoltaic (PV) generation results in challenges regarding network operation, management and planning. Correspondingly, Distribution Network Operators (DNOs) are in the need of totally new understanding. The establishment of comprehensive standards for maximum PV integration into the network, without adversely impacting the normal operating conditions, is also needed. This review article provides an extensive review of the Hosting Capacity (HC) definitions based on different references and estimated HC with actual figures in different geographical areas and network conditions. Moreover, a comprehensive review of limiting factors and improvement methods for HC is presented along with voltage rise limits of different countries under PV integration. Peak load is the major reference used for HC definition and the prime limiting constraint for PV HC is the voltage violations. However, the varying definitions in different references lead to the conclusion that, neither the reference values nor the limiting factors are unique values and HC can alter depending on the reference, network conditions, topology, location, and PV deployment scenario.

Ultra-reliable low latency (uRLL) communication in 5G dictates the deployment of distributed infrastructure with numerous datacenters for low latency, while hosting ultra-reliable services mandates attended datacenters. This would boost the operational costs of 5G network operators planning country-wide coverage for uRLL services. This paper examines how these operational expenses dominated by administrative costs can be reduced without impacting the quality of the provided uRLL service. Our results indicate that hosting uRLL services in unattended datacenters with increased hardware redundancy schemes can produce significant cost savings.

Abstract:

Although hosting sporting events has received considerable attention and the important connection between sporting events and urban development has been highlighted, most studies have focused on mega sporting events, and the controversy around the benefits of hosting mega sporting events is also increasing. To promote regional sport tourism, this study explores the strategic perspectives of stakeholders on hosting hallmark sporting events for the regional development of sport tourism. In-depth interviews were conducted with 11 representatives from stakeholder groups to discuss the role and essence of hallmark sporting events in promoting regional tourism. Archival material, including event organizing documents and information, was used to enhance the reliability of the qualitative analysis. Four strategic perspectives are proposed to illustrate the inter-relationships between hallmark sporting events and the sustainable development of regional tourism. These perspectives can be used as a management procedure to improve event operations for event managers. This study’s main contribution is the proposal of development goals and proper execution processes for hosting hallmark sporting events for the sustainable development of regional tourism, and the cultivation of effective synergy between local business activities and stakeholders.

Abstract:

Context. Planets are formed amidst young circumstellar disks of gas and dust. The latter is traced by thermal radiation, where strong asymmetric clumps have been observed in a handful of cases. These dust traps could be key to understanding the early stages of planet formation, when solids grow from micron-size to planetesimals. Aims. Vortices are among the few known asymmetric dust trapping scenarios. The present work aims to predict their characteristics in a complementary observable. Namely, line-of-sight velocities are well suited to trace the presence of a vortex. Moreover, the dynamics of disks is subject to recent developments. Methods. Two-dimensional hydro simulations were performed in which a vortex forms at the edge of a gas-depleted region. We derived idealized line-of-sight velocity maps, varying disk temperature and orientation relative to the observer. The signal of interest, as a small perturbation to the dominant axisymmetric component in velocity, may be isolated in observational data using a proxy for the dominant quasi-Keplerian velocity. We propose that the velocity curve on the observational major axis be such a proxy. Results. Applying our method to the disk around HD 142527 as a study case, we predict that line-of-sight velocities are barely detectable by currently available facilities, depending on disk temperature. We show that corresponding spirals patterns can also be detected with similar spectral resolutions, which will help to test against alternative explanations.

Abstract:

ABSTRACT Hypervelocity stars (HVSs) represent a unique population of stars in the Galaxy reflecting properties of the whole Galactic potential. Determining their origin is of fundamental importance to constrain the shape and mass of the dark halo. The leading scenario for the ejection of HVSs is an encounter with the supermassive black hole in the Galactic centre. However, new proper motions from the Gaia mission indicate that only the fastest HVSs can be traced back to the Galactic centre and the remaining stars originate in the disc or halo. In this paper, we study HVSs generated by encounters of stellar binaries with an intermediate-mass black hole (IMBH) in the core of a star cluster. For the first time, we model the effect of the cluster orbit in the Galactic potential on the observable properties of the ejected population. HVSs generated by this mechanism do not travel on radial orbits consistent with a Galactic centre origin, but rather point back to their parent cluster, thus providing observational evidence for the presence of an IMBH. We also model the ejection of high-velocity stars from the Galactic population of globular clusters, assuming that they all contain an IMBH, including the effects of the cluster’s orbit and propagation of the star in the Galactic potential up to detection. We find that high-velocity stars ejected by IMBHs have distinctive distributions in velocity, Galactocentric distance and Galactic latitude, which can be used to distinguish them from runaway stars and stars ejected from the Galactic Centre.

Abstract:

The hosting capacity approach is presented as a planning, improving, and communication tool for electrical distribution systems operating under specific uncertainties, such as power quality issues, power stabilities, and reliability, among others. In other words, it is an important technique, when renewable sources are present, to answer the amount of power that is possible to supply to the system without trespassing power performance limits. However, the power flow in a distribution system, for instance, can change throughout time due to the penetration of distributed generation, as well as load consumption. Based on the dynamic nature existing in distribution grids nowadays, it is important to highlight that the hosting capacity should not be calculated in a specifically chosen time only, but must be analyzed throughout a period of time. Thus, this paper introduces an extended concept of hosting capacity in relation to an integrated impact of harmonic voltage distortion and voltage rise as a function of time for daily, weekly, monthly, or even yearly periods. This extended concept is named as Dynamic Hosting Capacity (DHC(t)). General aspects of DHC(t) are demonstrated via measured data on a photovoltaic system (PV) connected at a low-voltage (LV) side of a university building.

Abstract:

Isolated communities are progressively integrating renewable generation to reduce the societal, economic and ecological cost of diesel generation. Unfortunately, as renewable penetration and load variability increase, systems require greater diesel generation reserves, constraining renewable utilisation. Improved diesel generator flexibility can reduce the requirement for diesel reserves, allowing increased renewable hosting. Regrettably, it is uncommon for utilities to modify diesel generator control during the integration of renewable source generation. Identifying diesel generator flexibility and co-ordination as an essential component to optimising system hosting capacity, this paper investigates improved diesel generator flexibility and coordination via low-load diesel application. Case study comparisons for both high- and low-penetration hybrid diesel power systems are presented in King Island, Australia, and Moloka`i, Hawai`i, respectively. For King Island, the approach details a 50% reduction in storage requirement, while for Moloka`i the application supports a 27% increase in renewable hosting capacity.

Abstract:

Future smart grids will be more dynamic with many variabilities related to generation, inertia, and topology changes. Therefore, more flexibility in form of several active and reactive power related technical services from different distributed energy resources (DER) will be needed for local (distribution network) and whole system (transmission network) needs. However, traditional distribution network operation and control principles are limiting the Photovoltaic (PV) hosting capacity of LV networks and the DER capability to provide system-wide technical services in certain situations. New active and adaptive control principles are needed in order to overcome these limitations. This paper studies and proposes solutions for adaptive settings and management schemes to increase PV hosting capacity and improve provision of frequency support related services by flexible energy resources. The studies show that unwanted interactions between different DER units and their control functions can be avoided with the proposed adaptive control methods. Simultaneously, also better distribution network PV hosting capacity and flexibility services provision from DER units even during very low load situations can be achieved.
