Texto completoResumen
In any given space, a sequence of interdependent Weber problems of a certain type leads to a pattern of locations which can be mathematically characterized. Conversely, the observed evolution of a given locational system corresponds to certain characteristics of an analogous Weberian locational system. Determining such characteristics leads to the simulating and forecasting of the evolution of the observed locational system. A model corresponding to such a ‘topodynamic’ approach is presented and an application is made. Three different effects are integrated into the model: an interdependency effect which determines the polarization level; an ‘attraction — repulsion’ effect which determines the center — periphery equilibrium; and a distance deterrence effect which determines the diffusion process and the inertia level.

While the Great Recession had clear effects on economic growth, unemployment, and household wealth and earnings in the United States, it also likely affected the quality of neighborhoods. Situated in the literature on locational attainment and economic shocks, this research considers how a national economic crisis affects physical neighborhood problems and existing disparities between minority and white households in experiencing these problems (e.g., street disrepair, trash, abandoned buildings, window bars). Results indicate that neighborhood problems increased between 2005 and 2009 and large and persistent disparities existed between some minority groups and white non–Hispanics in experiencing these problems, even after controlling for potentially confounding factors. However, there is little support for the idea that disparities between minorities and white non–Hispanics in experiencing neighborhood problems increased during this time. These research findings suggest that large and pervasive shocks, such as an economic recession, can influence locational attainment by changing neighborhood quality in absolute terms but may not affect the relative hierarchy of place.

Prediction of protein subcellular localization is an important issue in computational biology because it provides important clues for the characterization of protein functions. Currently, much research has been dedicated to developing automatic prediction tools. Most, however, focus on mono-locational proteins, i.e., they assume that proteins exist in only one location. It should be noted that many proteins bear multi-locational characteristics and carry out crucial functions in biological processes. This work aims to develop a general pattern classifier for predicting multiple subcellular locations of proteins. We use an ensemble classifier, called the min-max modular support vector machine (M3-SVM), to solve protein subcellular multi-localization problems; and, propose a module decomposition method based on gene ontology (GO) semantic information for M3-SVM. The amino acid composition with secondary structure and solvent accessibility information is adopted to represent features of protein sequences. We apply our method to two multi-locational protein data sets. The M3-SVMs show higher accuracy and efficiency than traditional SVMs using the same feature vectors. And the GO decomposition also helps to improve prediction accuracy. Moreover, our method has a much higher rate of accuracy than existing subcellular localization predictors in predicting protein multi-localization.

Locational analysis is a technique used for discovering, assessing, and specifying the optimal placement of an organization, information, activities, and materials. Locational analysis can include developing models, techniques, and tools to help provide solution to location-based problems. In this study, locational analysis is referred as the process of analyzing the variables such as topography or terrain, elevation, rainfall amount and its distribution, population density, and locations of prone areas, in order to arrange the placement of relief centres during flood events. This is a crucial concern for the preparation of an evacuation process in order to determine the necessary number of relief centres that should be set up for flood victims. Geng et al (2020) conducted their study on the basis of different needs of disaster victims, whereby shelters are divided into two types which are basic life and psychological medical service guarantee. They mentioned that at present, the location model of refugee facilities often ignores the diversion of shelter from the perspective of humanitarian logistics and the need of victims. They conclude that in this study they considered the full coverage of needs of victims and determine the location of shelter and the allocation of affected people to use certain facilities in large-scale emergencies for distributing suppliers.

Texto completoResumen
Terminals are key components of intermodal transport networks, as they are the facilities where freight is transferred between transport modes. The efficiency of such facilities crucially depends on their locations (and sizes), which are typically chosen considering two levels of analysis: local/urban and regional/country. Our focus in this presentation is the regional/country level. At this level, the problems involved in the locational (and sizing) decisions at stake are a particular variety of hub locations problems—a class of problems that has been widely studied through optimization approaches. However, they typically assume that decisions are made in a centralized management context: decision-makers not only choose the locations of intermodal terminals (or hubs), but also fully control their utilization (i.e., which terminal each user will patronize). This signifies that such approaches are not applicable when users–potentially, any companies that move freight–behave according to their own individual interests; that is, they are not applicable in a decentralized management context. In this presentation, we describe an ongoing study where (regional) intermodal terminal location problems are dealt with in this type of context considering terminals of different types and respective capacity and operation ranges. In particular, we present the complex optimization model we have developed to handle such problems, and the (sometimes counterintuitive) results it led to when applied to a case study inspired by the Portuguese reality.

Two types of equilibrium models of urban spatial structures are considered. An equilibrium version of the production-constrained spatial interaction model involving zonal-capacity constraints on allocation is investigated. A model of equilibrium for interacting subsystems is defined (it is a generalisation of Nash equilibria and of some Lowry-type models) and connections between this model and Nash equilibria are investigated. An entropy-projection operator is used for equilibrium urban models with zonal-capacity constraints. Problems of uniqueness of an equilibrium and the convergence of the iterative computational process are studied for these models.

Texto completoResumen
Aboriginal northern Great Lakes fishing strategies varied with season, target species, and organization of the labor force. The placement of Woodland archaeological sites complied with the structure of these fisheries, but their locations do not reflect prey specificity or one specialized technology. Rather, resource-general locations suggest an essential step in the process of specialization. Flexibility in settlement and social styles existed among prehistoric foragers of the midlatitudes, as did a variety of solutions to food-getting problems. Slow, accretional processes rather than temporally discrete growth processes were responsible for Late Woodland site characteristics in this region. Stable locational-selection patterns are visible through reexamination of the historical data base and through statistical analyses of environmental factors associated with sites at a number of Woodland localities.

The popularity of the sharing economy, including organizations such as Airbnb and Uber, has increased rapidly over the last few years. Regarding Airbnb, several studies have demonstrated potential problems related to it, such as rising housing costs and worsening residential environments. Despite its popularity and possibility of problems, however, the locational characteristics of Airbnb have not been thoroughly examined in the urban planning and public policy fields. Therefore, this study analyzed the locational characteristics of Airbnb in Seoul and identified potential problems in urban planning. First, we analyzed an operation status of Airbnb in terms of the commercial host. After that, we identified spatial distributions of Airbnb and examined influential factors that affected the locational characteristics of Airbnb using a negative binomial regression model. The results of this study are as follows. First, a considerable number of units were operated by commercial hosts, in contrast to the original concept of Airbnb as being part of the sharing economy. This finding indicates that there would be a potential conflict between Airbnb businesses and housing policy in urban areas. Second, Airbnb units were mainly located in residential areas, especially around multiplexes and townhouses. This finding indicates that Airbnb may decrease the availability of housing in the housing market. Third, Airbnb units were located preferentially in areas adjacent to universities or subway stations, as well as in areas with high ratios of single-person households. Considering these characteristics of Airbnb and the directions of government housing policy, urban scholars and policymakers should pay close attention to the potential conflict between the spatial distributions of Airbnb units and housing policies.

Tropical commercial poultry industry is anchored on exotic strains which suffer varying degrees of productivity and adaptability problems. Adaptability is the ability to produce better or demonstrate least variation in productivity under multiple environments. The study was undertaken to examine the productivity and adaptability of Bevan Nera (IB) and Is a Brown (IB) parent stock strains under two locations and seasons. Data on weekly feed intake (FI g), cock weight (Cockwt, g), hen weight (Henwt, g), hen house production (HHP, %) and egg weight (Ewt, g) were collected from a commercial parent stock breeding farm in Ibadan, Nigeria, on the two strains. Data were subjected to general linear model analysis (GLM) procedures using SAS (1999), while mean separation was by bonferoni t-test (P=0.05). The statistical model was randomized complete block design (RCBD) in factorial. Factors of importance were Genotype (S), Location (L) as Fixed, and Season (S) as random. The effects of location on seasonal productivity and season on locational productivity for strains were 7.38, 4.96; and 4.99, 8.11 (%) for BN, IB respectively. GxL and GxLxS interactions were significant (P<0.043 and <0.013) for adaptability of strains. Locational adaptability indices were 48.59 and 51.41 while Seasonal adaptability indices were 63.32 and 36.68 (%) respectively for BN and IB strains.

Abstract Just like in other industries, it is very important to choose the best possible location in hotel investments. As there are too many alternatives and changing touristic demands, there is serious competition within the hospitality sector. Therefore, all the investors want their properties located at the most profitable and competitive sites. To do so, they should decide the hotel location site by doing a well-analysed feasibility study. The hotel location selection can be influenced by some elements such as natural, economical, socio-cultural, legal, psychological factors and agglomeration effects. All of these factors have important roles of a hotel’s business success. However, especially in the last few years, the increasing numbers of hotel investments call in doubt that these factors are not considered properly. With this doubt, the main problems of this research have been revealed: what main factors do the investors consider in their investment decisions, and how do they decide the best site to locate the hotel? These problems also create the aims of this paper, which are to determine the factors that are important for investors and to find out where the most selected investment zones are. To achieve this goal, Istanbul has been divided into five agglomeration (investment) zones such as Historical Peninsula, Taksim-Beşiktaş-Şişli, Sarıyer-Maslak-Levent, Airport Area and Anatolian Side, according to their agglomeration effects. Then, interviews were completed with six hotel investors from these areas in order to get their opinions about the investment decisions. The gathered information has been analysed by the fuzyy TOPSIS method, which helps to calculate the subjective thoughts of the investors in a quantitative way. Then, the order of preference within the investment zones was calculated to determine the most popular site among the investors. The results showed that the most important factors for hotel location selection are agglomeration effects and economical factors. According to the order of preference, the most preferred location site has been determined as the Historical Peninsula, which includes Fatih, Eminönü, Sultan-ahmet and Topkapı zones.

An experimental satellite collar was tested on a captive bull muskox (Ovibos moschatus) and a wild cow muskox in north-eastern Alaska. The animals had no observed problems carrying the 2.2-kg collar. The satellite collar provided frequent data on location and activity of the muskox as well as internal temperature of the collar canister. During a 12-month period, 329 locations were obtained from the wild cow muskox with a locational error ranging from 0.28 to 2.46 km. Fewer locations were obtained in winter than summer, but amounts of data received on activity and temperature were relatively consistent year-round. A counter that recorded closure of a mercury tip switch at 1-min intervals for 30 min was useful for determining if the animal was active or resting. Home range size, movements, and activity of the satellite-collared cow muskox were all reduced in winter.

Models for estimating urban rental house prices in the real estate market continue to pose a challenging problem due to the insufficiency of algorithms and comprehensive perspectives. Existing rental house price models based on either the geographically weighted regression (GWR) or deep-learning methods can hardly predict very satisfactory prices, since the rental house prices involve both complicated nonlinear characteristics and spatial heterogeneity. The linear-based GWR model cannot characterize the nonlinear complexity of rental house prices, while existing deep-learning methods cannot explicitly model the spatial heterogeneity. This paper proposes a fully connected neural network–geographically weighted regression (FCNN–GWR) model that combines deep learning with GWR and can handle both of the problems above. In addition, when calculating the geographical location of a house, we propose a set of locational and neighborhood variables based on the quantities of nearby points of interests (POIs). Compared with traditional locational and neighborhood variables, the proposed “quantity-based” locational and neighborhood variables can cover more geographic objects and reflect the locational characteristics of a house from a comprehensive geographical perspective. Taking four major Chinese cities (Wuhan, Nanjing, Beijing, and Xi’an) as study areas, we compare the proposed method with other commonly used methods, and this paper presents a more precise estimation model for rental house prices. The method proposed in this paper may serve as a useful reference for individuals and enterprises in their transactions relevant to rental houses, and for the government in terms of the policies and positions of public rental housing.

The article focuses on problems of current tendencies differentiating between borderland and inland, and among border regions themselves. First, the borderland - inland differences are still limited, but they will be probable deepening in future. Second, the differences among border regions are important both in intensity of settlement and in economic level, and in current development dynamics. Key factors of regional differentiation appear to be xxxx - locational position and inherited economic specialization.

Texto completoResumen
This is the second of two papers in which multiple criteria location problems (MCLPs) are discussed. In this paper two major approaches to locational decisionmaking are overviewed: optimizing decision rules (utility-function-based methods) and satisficing decision rules (goal-programming methods). Their advantages and disadvantages are discussed. From these two concepts a quasi-satisficing decision rule is developed and operationalized through a reference point method. A framework for an interactive decision support system (DSS) for tackling MCLPs is proposed. The system integrates a network model with the quasi-satisficing approach. It is argued that the DSS data and analytical components can be effectively integrated by means of the interactive decision support concept that involves a feedback exchange of information between a decisionmaker and a computer-based support system. This concept allows for the exploration of the locational decision problem and the alternative solutions both in decision space and in criterion outcome space.

Abstract Approximately 600 micro and small business owners in Kenya, Ghana and Nigeria were surveyed to better understand their perceived success factors and ongoing problems. According to the entrepreneurs, hard work, good management skills and good customer service are the most important ingredients for success. Fifteen of the 17 success items could be broken into four factors. The factor for controllable non-managerial items was seen as the most important factor governing success for entrepreneurs from all three countries. The most significant problems as reported by entrepreneurs were a weak economy and unreliable employees. A factor analysis of the problems revealed significant differences among the three countries. Ghanaian entrepreneurs were less concerned about their lack of training and locational issues and more concerned about their lack of capital. Compared to Ghanaian and Kenyan entrepreneurs, Nigerians had greater concern with the factor related to safety, location and employees.

Texto completoResumen
In real-time electricity markets, locational marginal prices (LMPs) can be determined by solving multi-interval economic dispatch problems to manage inter-temporal constraints (i.e., ramp rates). Under the current practice, the LMPs for the immediate interval are binding, while the prices for the subsequent intervals are advisory signals. However, a generator may miss the opportunity for higher profits, and compensatory uplift payments are needed at the settlement. To address these issues, the “temporal locational marginal pricing (TLMP)” that augments LMP by incorporating multipliers associated with generators’ reported ramp rates was developed. It was demonstrated that it would result in zero uplift payments, showing great potential as a good pricing scheme. Numerical examples also showed that “the generators had incentives to reveal their ramp rates truthfully”. In this paper, the incentive compatibility of TLMP with respect to ramp-rate reporting is discussed. Our idea is to develop numerical examples to investigate whether reporting the true ramp rates is the best option for generators. The results indicate that TLMP is not incentive compatible, and there are market-clearing scenarios where not reporting true ramp rates may be beneficial.

Texto completoResumen
The present article deals with the dative external possessor construction in Latvian. Attention is drawn to the widespread occurrence of this construction, extending to constructions with relational nouns practically functioning as adpositions. The carrying-over of the external possessor construction to what would otherwise be described as adpositional phrases creates certain problems for syntactic description. Emphasis is, however, on the semantic aspects. The features commonly associated with the external possessor construction, such as animacy, sentiency and affectedness, play no role here. It is suggested that the differences between the constructions with genitive and dative in spatial expressions with relational nouns are connected with the figure-ground configuration, the constructions with the dative serving to mark the shift of saliency from the figure (located object) to the ground (reference object). This, it is argued, is not an accidental extension of the external possessor construction to a domain where is was not originally applicable, but reflects the general principles underlying the external possessor construction. This can be formulated as the shifting of cognitive or discourse saliency from the figure/possessum to the ground/possessor in a locative/possessive structure.

In this paper I focus on the problems that face (teacher) education policy and practice in meeting the challenge of ‘persistent and entrenched locational disadvantage’ in marginal communities. In Dropping off the Edge 2015, Tony Vinson and colleagues (2015) clearly demonstrate that complex and entrenched disadvantage has continued to characterise a number of Australian communities, with few signs of improvement in the past 15 years. A very high proportion of these disadvantaged localities are in rural areas, and they pose an enormous challenge to policy makers and service providers, as well as to the people who live in the communities themselves. In such contexts, education is both crucially important and inexorably difficult. Agreeing with Vinson, Rawshtorne, Beavis and Ericson, that we need to understand locational disadvantage as a wicked problem for a social equity agenda (2015), I argue that the concept of Rural Social Space (Reid et al., 2010) provides a useful and coherent theoretical resource for understanding and addressing this problem, and rethinking the idea of community in ways that are necessary for change to occur. Using an exemplary case of one locality identified by Vinson as threatened with ‘dropping off the edge’, I examine what a wicked problem looks like for social equity in this particular rural social space, and how it calls into question some of our most cherished assumptions about rural communities and rural schooling. The example allows consideration of the kind of policy and practice responses that may be necessary if the problem of educational disadvantage in rural locations is to be adequately addressed.

Texto completoResumen
When considering the economic and environmental aspects of forestry, especially the issues related to timber harvesting, emphasis should be placed on the importance of the availability of raw material resources for the sustainable flow of goods. It would also be difficult to disregard certain issues related to transport, which play a key role in the efficient flow of wooden raw materials. It has to be noticed that timber transport options are limited by a number of factors, including the considerable fragmentation of wood resources and the lack of adequately developed railway transport facilities. This paper focuses on issues related to the road transport of timber carried out by transport companies. Observations to date of large-sized roundwood (thicker than 14 cm and longer than 3 m) transport in Poland indicate a relatively frequent occurrence of overloaded vehicles, exceeding the permissible total weight limit. Empirical evidence also suggests that in many cases, it is an effect of improperly endorsed standards with regard to the density of the transported material. Moreover, there is a clear correlation between the loading volume and economic as well as environmental factors. Therefore, the aim of this article was to show both the current situation in the transport of bulky timber and to present the possibilities for its optimization, from the point of view of locational, economic and environmental factors.

This article contrasts traditional modeling approaches and discrete-choice models as methods to analyze locational attainment—how individual and household characteristics (such as race, socioeconomic status, age) influence the characteristics of neighborhoods of residence (such as racial composition and median income). Traditional models analyze attributes of a neighborhood as a function of the characteristics of the households within them; discrete-choice methods, on the other hand, are based on dyadic analysis of neighborhood attributes and household characteristics. I outline two problems with traditional approaches to residential mobility analysis that may be addressed through discrete-choice analysis. I also discuss disadvantages of the discrete-choice approach. Finally, I use data from the Panel Study of Income Dynamics to estimate residential mobility using traditional locational attainment and discrete-choice models; I show that these produce similar estimates but that the discrete-choice approach allows for estimates that examine how multiple place characteristics simultaneously guide migration. Substantively, these models reveal that the disproportionate migration of black households into lower-income tracts amounts to sorting of black households into black tracts, which on average are lower income.

The term ‘Ibadan School’ is used here in two senses, locational and generic, and refers to studies on, and students of, federal finance that have employed a distinctive approach. Some of the most dominant figures in this group are (or used to be) on the staff of the University of Ibadan, and when it was decided after independence in 1960 that Nigerians themselves should handle the recurrent problems of federal finance, the task fall on the laps of a number of western-trained, liberal, and orthodox economists.

Although there has been increasing interest in rural enterprises, relatively little has been written on enterprise and entrepreneurship on islands where problems tend to be different, additional and exaggerated. Economic and cultural development agencies intervene to support such remote and isolated communities but the significance of the dominant metropolitan paradigm in the peripheralization of those establishing and running businesses on islands needs critiqued. This article contrasts experiences but highlights similarities, rather than differences, of rural small and medium enterprises (SMEs) in developing countries and comparative Northern European locations. The key role of social capital, cultural values and norms is analysed and comment presented on small island experiences. Arguments are made for policies to be proofed for locational differences and for further research to understand the opportunities offered by islands and coastal communities in a world where the particularities of place and space are increasingly valued, and aspects of remoteness can be rearticulated to good effect.

Abstract. The successful bid for the 2022 Winter Olympics (Beijing 2022, officially known as the XXIV Olympic Winter Games) has greatly stimulated Chinese enthusiasm towards winter sports participation. Consequently, the Chinese ski industry is rapidly booming due to enormous market demand and government support. However, investing in ski areas in unreasonable locations will cause problems from an economic perspective (in terms of operation and management) as well as geographical concerns (such as environmental degradation). Therefore, evaluating the suitability of a ski area based on scientific metrics has become a prerequisite for the sustainable development of the ski industry. In this study, we evaluate the locational suitability of ski areas in China by integrating their natural and socioeconomic conditions using a linearly weighted method based on geographic information system (GIS) spatial analysis combined with remote sensing, online, and field survey data. The key indexes for evaluating natural suitability include snow cover, air temperature, topographic conditions, water resources, and vegetation, whereas socioeconomic suitability is evaluated based on economic conditions, accessibility of transportation, distance to a tourist attraction, and distance to a city. As such, metrics ranging from 0 to 1 considering both natural and socioeconomic conditions are used to define a suitability threshold for each candidate region for ski area development. A ski area is considered to be a dismal prospect when the locational integrated index is less than 0.5. The results show that 84 % of existing ski areas are located in areas with an integrated index greater than 0.5. Finally, corresponding development strategies for decision-makers are proposed based on the multicriteria metrics, which will be extended to incorporate potential influences from future climate change and socioeconomic development. However, the snowmaking model with local data should to be used to further analyze the suitability for a specific ski area.

Research is currently being conducted at the Virginia Transportation Research Council to determine some of the problems associated with the implementation of a geographic information system (GIS). The collection and development of the data sets required to drive the GIS are two of the largest expenses associated with GIS implementation. This research looked at the feasibility of using the global positioning system (GPS) to collect point, line, and polygon features that are representative of some of the locational and attribute data required to run the Virginia Department of Transportation’s (VDOT’s) GIS. Data sets identified in VDOT’s 10-year GIS strategic plan were collected and transferred to ARC/INFO, a proprietary system, by way of handheld, mapping-grade GPS receivers. Methods for the collection and transfer of the data sets are outlined. Point accuracies of approximately 2 m were obtained. Time requirements and data collection problems are also described.

Texto completoResumen
Decision making in modern forest management planning is challenged by the need to recognize multiple ecosystem services and to address the preferences and goals of stakeholders. This research presents an innovative a posteriori preference modeling and multi-objective integer optimization (MOIP) approach encompassing integer programming models and a new technique for generation and interactive visualization of the Pareto frontier. Due to the complexity and size of our management problems, a decomposition approach was used to build the Pareto frontier of the general problem using the Pareto frontiers of its sub-problems. The emphasis was on the approximation of convex Edgeworth–Pareto hulls (EPHs) for the sub-problems by systems of linear inequalities; the generation of Edgeworth–Pareto hulls by the convex approximation of the Pareto frontier evinced a very small discrepancy from the real integer programming solutions. The results thus highlight the possibility of generating the Pareto frontiers of large multi-objective integer problems using our approach. This research innovated the generation of Pareto frontier methods using integer programming in order to address multiple objectives, locational specificity requirements and product even-flow constraints in landscape-level management planning problems. This may contribute to enhancing the analysis of tradeoffs between ecosystem services in large-scale problems and help forest managers address effectively the demand for forest products while sustaining the provision of services in participatory management planning processes.

Africa is poorer than any other region in the world. Many countries are chaos-stricken, and most observers see a long-term decline. Structural adjustments have done so far less in order to solve at least some of the deep problems. Capitalism is not far-reaching, and the informal economy dominates the lives of the majority of the people. Will the informal economy, which is growing in the urbanisation process, form the basis for an alternative “endogenous economy”? This study identifies the growth perspectives of small and medium enterprises and industrial clusters. And it looks into new growth and locational theories, which have argued that agglomerations might favour local production and investment in a globalized world.

Texto completoResumen
This is an historical inquiry into the events that led to Fesler’s 1949 maxim that federal field administrative regions should always be larger than an individual state. When he proclaimed that principle he concluded that state-based regions caused political problems for personnel and locational reasons, but only presented a single contemporary example for each of those reasons. Relying on primary and archival sources, this article provides additional historical proofs for Fesler’s maxim. It discusses several largely forgotten political controversies that occurred during the Presidency of Franklin Roosevelt regarding state-based federal administrative regions. This reconstruction is a form of forensic public administration history, seeking to give a clearer understanding of why Fesler addressed the subject at all and providing additional factual substantiation for his axiom.

Traditional taxi services have now been transformed into e-hailing applications (EHA) such as Uber, Careem, Hailo, and Grab Car globally due to the proliferation of smartphone technology. On the one hand, these applications provide transport facilities. On the other hand, users are facing multiple issues in the adoption of EHAs. Despite problems, EHAs are still widely adopted globally. However, a sparse amount of research has been conducted related to EHAs, particular in regards to exploring the significant factors of intention behind using EHAs Therefore, there is a need to identify influencing factors that have a great impact on the adoption and acceptance of these applications. Hence, this research aims to present an empirical study on the factors influencing customers’ intentions towards EHAs. The Technology Acceptance Model (TAM) was extended with four external factors: perceived mobility value, effort expectancy, perceived locational accuracy, and perceived price. A questionnaire was developed for the measurement of these factors. A survey was conducted with 211 users of EHAs to collect data. Structural equation modeling (SEM) was used to analyze the collected data. The results of this study exposed that perceived usefulness, perceived price, and perceived ease of use affect behavior intention to use EHAs. Furthermore, perceived ease of use was impacted by effort expectancy, perceived locational accuracy, and perceived mobility. The findings of the study provide a foundation to develop new guidelines for such applications that will be beneficial for developers and designers of these applications.

The impacts of satellite geodesy are being felt in all aspects of human development and environmental management. Its principal advantages stem from the global nature of its scope, the diversity of its sensors and the realtime capabilities to capture both visual, numerical and other data types for as long as desired and in all weather conditions. The capacity to pinpoint locations to high precision in fractions of a second and provide detailed geometric and graphical definitions of large swaths are proving useful for meeting the needs of a people desirous for automation in all aspects of human endeavours and for confronting the increasing challenges of sustainable development and environmental degradation. The most innovative facility provided by satellite geodesy is the technology of remote sensing which enables measurements of objects without physical contact for interpretative and mensurative analysis and mapping in static or kinematic modes. The aim of this paper is to showcase the contributions of satellite geodesy to sustainable environmental management its basic concepts and a brief exploration of some of its applications. The overall objective is to underscore its critical role in socio-economic development. The paper posits therefore that today’s rapidly changing environmental problems requiring static and realtime locational and graphical solutions can be solved through the facilities of satellite geodesy.

Abstract: The purpose of this study is to present and develop a practical advertising model that minimizes transport advertisements, indiscriminate banners and flyers, and logo light installation problems with smart advertisements using projected beams. In order to develop an integrated smart advertisement that is convenient and inexpensive for companies operating at night, the scope of the research is determined as a practical advertisement that identifies the problems of existing bus and taxi smart advertisements and the needs of customers. The smart projected beam advertisement that the author claimed is a customized advertisement that solves the advertising problems of customers and local governments in Korea based on business hours, locational information, and big data. The projected beam outdoor advertising system developed by the author was designed to reduce environmental and resource waste, avoid unnecessary advertisement exposure for consumers, and obtain necessary information for businesses. Moreover, it was developed to reduce advertising costs for businesses. This is a very appropriate solution as an alternative to reduce the night time flyers and banners that local governments in Korea are struggling with. Consumers can avoid unnecessary advertisement exposure and obtain customized information, while advertisers who use the service can directly insert their sales information into advertisements in real-time using various media at a low cost.

Assam is endowed with a large number of wetlands of different kinds. The number and areas of wetlands are variously distributed over the state. Assam has a total wetlands area of 1012 sq.kms with 3514 wetlands representing the highest area under wetlands among the North Eastern states. More than 80 percent of the wetlands falls in Assam regions, which suggest that majority of the regions wetlands originates in the fluvial domain of the Brahmaputra River system. Wetland distribution in district level reveals that Nagaon District has the highest number of wetlands among all the districts of the state. Depending on their locational characteristics, the wetlands are prone to various kinds of geo-environmental problems. Therefore, with growing need of wetlands management, it has become highly imperative to study genesis and development of wetlands.

The distribution and the competence of firefighting stations in koya town is one of the main problems that this town suffers from, and this led us to conduct an academic study in this respect with the use of Geographic Information Systems. This system illustrates the competence and the services of firefighting stations according to world standard in terms of the times that they take (3-5 minutes) to arrive at the destination according to the distance and the road network, so based on these criteria, the firefighting service can only cover (34%) of the town. It can be deduced that this problem mainly results from misdistribution of firefighting stations and the poor road transportation network. This study, basing on the universal standards, proposes five new firefighting stations in koya in order to be able to cover the whole town and offer a good service in this respect for the present time and for future.

John Herbert Orr (1911-84) was an Alabama entrepreneur who formed Orradio Industries, Inc., a pioneering hightechnology firm that made magnetic recording tape. In 1945, Orr was among the U.S. Army Intelligence officials who investigated this technology, which was originally developed in Germany during the 1930s. Orr's early knowledge allowed him to establish Orradio in 1949 on a shoestring budget and to make it competitive with larger firms. When, after some uncertainty, tape became the standard medium for magnetic recorders, and as other uses such as data storage and videotape appeared, Orradio's sales expanded rapidly in the late 1950s. The company was purchased by a larger competitor, the Ampex Corporation, in 1959. The history of Orradio illustrates some of the technological, organizational, and locational problems associated with the establishment of a small high-technology firm in a new industry.

Texto completoResumen
Screw Theory is used to provide mathematical models of assembly features, allowing the determination of positioning constraints imposed on one part in an assembly by another part based on the geometry of the features that join them. Several feature types have been modeled, and it is easy to model new ones. A user of this theory is able to combine members of this set to join two parts and then determine whether or not the defined feature set over-, under-, or fully-constrains the location and orientation of the part. The ability to calculate the state of constraint of parts in an assembly is useful in supporting quantitative design of properly constrained assemblies in CAD systems. Locational over-constraint of parts can lead to assembleability problems or require deformation of parts in order to complete the assembly.

Soviet intervention in Afghanistan clearly indicates the strategic implications of its location. The political instability in the region (rise of fundamentalism in Iran, Iran-Iraq War and so on) has added to this significance. Be that as it may, Afghanistan's situation can be expressed in terms of its susceptibility to external pressures and intense factionalism within the land-locked state's dynamic populations. This latter aspect had divided the country several times over. Afghan foreign policy, therefore, has been viewed in this perspective. The present article reviews the stated facts to highlight the geographical significance of the location and its impact on the foreign policy. Introduction of the armed forces in national politics (this formed an important element in the country's politics right from the beginning) has been the most conspicuous development; it determined the who's and what's of the government. Traditional pressure groups, despite retaining some of their old hold on the society, had given way to radical groups or factions, armed forces and insurgent elements. These penetrated various strata of the Afghan society. Since 1963, when political liberalisation and participation was introduced, disruptive tendencies gradually impinged on the state's activities. Generally, this was evident between 1963–73 and was particularly so after the 1973 coup, when the Monarchy was replaced by a republican regime under Daud. Both, the Armed Forces and the Communist Party were involved but were sidelined once power was secured. This change did not bring the expected transformations in the patterns of administration. The change was only in name and power was still concentrated with Daud who began to implement his own policies that emerged between 1953–63. The period of his first stint in power coincided wiih an aggravation of problems, political and economic, caused by a closure of transit facilities. However, this pause was fully exploited by the radical parties who gradually brought the dominant elements of the Armed Forces under their influence, so that, they were able to deliver a coup d'etat under the leadership of Tarakki in April 1978. The new regime was not able to maintain effective control over the political situation that for the next twenty months brought internal political instability to its height and compelled the Soviet Union to move (this was perhaps to protect its vulnerable southern underbelly). The period from April 1978 onwards, saw active non-cooperation, large scale desertions from the Armed Forces and a deterioration of the economy. In addition, open opposition by the religious groups and insurgent elements presented a political picture that has been so vividly illustrated by Afghan political history. Intense factionalism and infighting within the regime saw Amin replacing the moderate Tarakki in September 1979. This led to a worsening of the political situation with the state at war with itself. This compelled the Soviet Union to move into Afghanistan. In a short but bloody war, Amin was disposed and a government under Karmal was established with Soviet support1. These developments then, clearly suggest the need to review the background of the patterns and problems of the foreign policy of Afghanistan as determined and identified by its locational characteristics.

ABSTRACTSolok City is within range of the Sumatera active fault where destructive earthquakes have happenedfrequently (Padang Panjang earthquake 1926, Singkarak earthquake 1943 and 2004, and Solokearthquake 2007). Problems arise when most of the population often quickly forget the danger offuture earthquakes and the mitigation efforts to reduce disaster hazards. New housings were stillbuilt in areas highly prone to earthquakes. The study investigated the factors affecting thelocational choice for housing in post‐earthquake Solok City using qualitative descriptive format.Post earthquake locational analysis of housing areas showed that cumulatively 47% of the houseswere built in ‘high’ to ‘very high’ vulnerability area meaning that almost half of the houses built in theyear 2010 are exposed to high risk from earthquakes. Analysis found four latent factors affecting thechoice for housing location post 2007 Solok earthquake included (1) Earthquake Vulnerability, (2)House Prices, (3) Accessibility, and (4) Policy and Social factors. Analysis showed how earthquakevulnerability was indeed the priority factor in the choice of location for the general society. Howeverthis is contradictory to the reality of the current locations of housing areas built after the 2007earthquake. The general society considered earthquake as very important but they built their housesin the disaster prone ares anyway. Therefore a common awareness needs to be established among allstakeholders to reduce the risks and improve mitigation efforts in case of future disasters.Keywords: earthquake vulnerability, housing location choice, post‐earthquake

Texto completoResumen
The use of a zonal structure for energy markets across the globe is expanding; however the debate on how to effectively partition the grid into bidding zones is still open for discussion. One of the factors that needs to be addressed in the process of bidding zones’ delimitation is the transmission system operators control areas. Merging parts of different control areas into one bidding zone can lead to multiple problems, ranging from political, through grid security concerns, to reserve control issues. To address it, this paper presents a novel grid partitioning method aimed at bidding zones delimitation that is based on clustering the power grid using an extended version of the standard agglomerative clustering. The proposed solution adds additional clustering rules when constructing the dendrogram in order to take into account the control areas. The algorithm is applied to the data which represents the locational marginal prices obtained from optimal power flow analysis.

In comparative studies of language proficiency and grades, Filipino second generation youth look relatively successful and assimilated, echoing what we know about their parents: post-1965 Filipino immigrants are predominantly middle-class, college-educated, English-speaking professionals who have integrated easily into U.S. society. Based on fieldwork in two California sites, this paper examines some of the issues and problems confronting second generation Filipino youth. “The family” seems to offer an extremely magnetic and positive basis of Filipino identity for many children of immigrants, yet it is also a deep source of stress and alienation, which for some, has led to internal struggles and extreme despair as manifested by rates of depression and suicidal thoughts. More specifically, by focusing on the gap between family ideology and practices, this paper suggests that many Filipino second generation youth struggle with an emotional transnationalism which situates them between different and often conflicting generational and locational points of reference.

In this paper, the authors propose solutions to increase the added value of coffee in the form of the process of making the process of making coffee using appropriate technology adoption. This paper uses qualitative methods of locational survey and literature study. Survey activities are conducted in the form of interviews and observations. The team conducted interviews with coffee farming communities in the area and observed the conditions of coffee farming. The literature study was conducted by synthesizing literature reviews and continued by formulating the theory and principles of appropriate technology in the context of local agriculture in Sukawangi Village, Sumedang Regency, West Java. In this paper, the authors describe the solution proposals related to the problems of coffee farmers in Sukawangi, Sumedang. Two suggestions for increasing the value added of coffee beans are by using appropriate technology adoption. With both of these solutions, it is expected that the quality of coffee plantation in Sumedang can be increased and can be marketed in both domestic and international markets. As a result, the welfare of farmers in Sumedang will increase.
