Sports facilities can play a vital role in encouraging physical activity and sport. Also, just the distribution of sports facilities is very important for better access to these facilities. Therefore, the purpose of this study is to evaluate spatial justice in the distribution of built outdoor sports facilities in the city of Isfahan, Iran and provide insight for planning in terms of equitable accessibility.

All facilities located in the 15 areas of the city, whether private or public, built for the purpose of physical activity and sports programs were considered in this study (107 cases). To obtain information on the locations of the outdoor sports facilities, Isfahan Atlas data, which has been compiled by Isfahan Municipality was used. Arc geographic information systems environment and its different algorithms were also used to perform different calculations and prepare maps.

The results indicated the unfair distribution of built outdoor sports facilities in the city of Isfahan in terms of spatial justice based on the number of built outdoor sports facilities in each area, the population, land area, population density and the spatial pattern of the facilities.

In this regard, urban authorities and sport managers should make an effort to decrease or obviate inequity in access to outdoor sports facilities for the purpose of promoting participation in physical activity and sport and providing residents with numerous other benefits.

This paper has concluded that spatial justice in the distribution of built outdoor sports facilities for the improvement of access to these facilities is very important.

This paper aims to investigate the effects of economic growth, population density and international trade on energy consumption and environmental quality in India.

Taking annual data of 1971-2011, autoregressive distributed lag bounds testing technique is applied to explore the long run link between the series. The Granger causality test is used to determine the direction of causality between the variables.

The obtained results confirm the cointegration of variables, and economic growth and population density are found to have significant positive effects on energy consumption in both the short and long runs. CO₂ emissions are also positively and significantly affected by population density and energy consumption, and negatively affected by economic growth.

The paper is original and valuable in the sense that it has considered two relevant additional explanatory variables, namely, population density and trade openness, which got little attention in the past. This research is an improvement over the previous studies because it has looked at the separate effects of explanatory variables on energy consumption, in addition to the effects on carbon emissions. Therefore, the findings of this research are more reliable because this adopted methodology is better and extensive, and the authors have properly addressed the issue of omitted variable bias.

The purpose of this research is to investigate the effect of operational efficiency, gender of the borrowers and the population density on the performance of microfinancing institutions that play a significant role in alleviating poverty in developing countries.

A model showing the relationships among the variables is first proposed based on the hypotheses developed in the literature review. Then the model is tested with empirical data using multiple regression and path analysis. Data used in the analysis relate to 234 microfinancing institutions across 63 countries.

The study finds that operational efficiency and gender of the borrowers have a direct impact on the performance of microfinancing institutions. Although population density does not have a direct impact on performance it has an indirect effect through operational efficiency and gender of the borrowers.

The findings of this study reveal to the policy makers and managers of microfinancing institutions the importance of focussing on the three factors analysed (operational efficiency, gender of the borrowers and population density) to reduce poverty.

The study enhances the current knowledge in the literature relating to microfinancing. The findings help to improve the performance of microfinancing institutions resulting in efficient and effective utilisation of hundreds of millions of donor funds originating from tax payers in developed countries.

The purpose of this paper is to examine the relationship between a foreign firm’s likelihood to exit a host country and the population density of foreign firms in its industry in that county, as well as the moderating influences of this relationship. The authors hypothesize that a foreign firm’s likelihood to exit has a U-shaped relationship with foreign firms’ population density in the industry and this relationship will be weakened when: the foreign firm is located in a region where foreign firm presence is high; the foreign firm is in an industry that has a longer history of foreign direct investment; the firm has a longer tenure in the host country; and the firm is more adapted to the market and institutional environments of the host country.

The authors test the hypotheses using a data set containing over 45,000 foreign firms in China between 1998 and 2007.

The results show that the exit likelihood of a foreign firm has a U-shaped relationship with foreign firms’ population density in the firm’s industry in the host country. Furthermore, this relationship is moderated by the population density of foreign firms in the region where the firm resides, the length of time since the first foreign entrant in the industry and the extent of the focal firm’s local adaptation.

The study contributes to organizational ecology theory and the international business literature by extending the density-dependence model to the study of foreign firm survival/exit. Whereas a foreign firm’s fate in the host country is heavily influenced by the population density of foreign firms in its industry, it can borrow legitimacy from other sources, or try to create legitimacy through its own actions, to reduce the impact of such density effects.

This study aims to examine how evolutionary and ecological forces shape the market strategy and performance of firms after their organizational form was changed by exogenous shock.

Hypotheses are developed based on both evolutionary and ecological perspectives and tested using fixed effect logistics models and a sample of 3,110 firms that were privatized during 1998–2007.

I find that once the organizational form of firms is changed, the market strategy of organizations is shaped by the population density of their old and new organizational forms in their existing market. Moreover, such a market strategy enhances the survival chance of firms.

This study contributes to organizational evolution literature by unpacking the evolution process when exogeneous shock to organizational form takes place. It advances both evolutionary economics and organization ecology theory through integrating them to understand the evolution process of organizations. This study also contributes to the privatization literature through examining the ecological forces that shape the restructuring strategy of firms after privatization and the performance implications of such restructuring.

The intended nationally determined contributions (INDCs) is a major outcome of the Paris Agreement on international cooperation to reduce emissions, and is likely to be the future scenario for carbon emissions. This paper aims to obtain the fine spatial pattern of carbon emissions in 2030, identify hot spots and analyze changes of carbon emissions with a spatial grid method.

Based on the integrated quantified INDCs of each economy in 2030, the authors predict the population density pattern in 2030 by using the statistics of current population density, natural growth rates and differences in population growth resulting from urbanization within countries. Then the authors regard population density as a comprehensive socioeconomic indicator for the top-bottom allocation of the INDC data to a 0.1° × 0.1° grid. Then, the grid spatial pattern of carbon emissions in 2030 is compared with that in 2016.

Under the unconditional and conditional scenarios, the global carbon emission grid values in 2030 will be within [0, 59,200.911] ktCO₂ and [0, 51,800.942] ktCO_2, respectively; eastern China, northern India, Western Europe and North America will continue to be the major emitters; grid carbon emissions will increase in most parts of the world compared to 2016, especially in densely populated areas.

While many studies have explored the overall global carbon emissions or warming under the INDC scenario, attention to spatial details is also required to help us make better emissions attributions and policy decisions from the perspective of the grid unit rather than the administrative unit.

The purpose of this paper is to examine the development cycle of Brazilian banking sector during the lengthy period between 1889 and 2009, also identifying an equilibrium number of financial institutions based on the carrying capacity of the environment.

The number of institutions in equilibrium is calculated based on the population density dependence model adopted under the organizational ecology theory. Quantitative data of founding and failure and qualitative data (interviews with the directors, officers and chief executive officers (CEOs) of selected companies) were used.

In all three bank segments (commercial, investment and multiple), the total number of banks in operation on December 31, 2009 was below the carrying capacity. However, in the multiple bank segment, the gap between the actual and potential figures is slightly smaller. As indicated by the respondents, there is almost no room for newcomers in the major bank segments. In counterpart, there is still space for new arrivals in the mid-market bank sector.

The findings presented here may change, as carrying capacity is determined by political, legal and economic factors, including the availability of resources in niches and constraints imposed through laws, rules and other regulatory aspects. However, raising the life cycle of the entire population offers opportunities for future research on individual organizational trajectories, using new theoretical and methodological perspectives, such as dynamic capabilities and process theory.

The main contribution of this paper lies in indicating the growth potential for banking institution populations in Brazil, and may be used not only by potential newcomers eager to enter the sector, but also as a tool for assessing anti-trust policies.

The development cycle of Brazilian financial institution populations is unknown, and carrying capacity is a construct less explored by academic literature, particularly in Brazil. This is a unique study since a demography of an entire banking population in a developing country does not exist, besides there is not such a financial institution like the multiple bank in Brazil.

Understanding when new forms will emerge constitutes a core theoretical issue for organizational theory. The ecological theory of form emergence falls short of providing a full explanation because it treats legitimation as a primitive (unexplained) concept. Here, we use Hannan, Pólos, and Carroll's (2007) revised theory of organizational evolution to interpret and respecify the legitimation part of the density dependence model. Among other advantages, the respecification allows us to incorporate the insights of the “cultural-frame” institutional perspective. We study early Dutch accounting, an industry setting where form legitimation was fiercely contested by several professional associations in the period 1884–1939. We develop an analytical narrative about the historical legitimation process, and we also present systematic tests of the theory examining predictions about “fuzzy” density and population contrast. Estimated models of firm exit support the revised theory and reveal that fuzziness, induced from fragmented collective action, hampers it.

The purpose of the paper is to define the best deployment alternatives for a public protection and disaster relief (PPDR) mobile network service – the implementation alternatives being either a dedicated network, a commercial network or a hybrid of the two network types. The selection criteria are based on the social benefits that the PPDR mobile service is expected to bring to society. The critical parameters are population density and service availability, which both directly relate to the socioeconomic benefits achieved by providing broadband (BB) mobile services in various demographic areas.

A causal loop model has been developed to define the socioeconomic benefits of the PPDR network, the parameters being population density, service availability, socioeconomic value of the service and the costs of the network. The network solution alternatives are studied using the Finnish PPDR network as a reference – analysing various areas of the country with differing population densities from remote, rural and more densely populated suburban and urban areas.

Socioeconomic value is a common measure for assessing the value of governmental investments; population density has a strong impact on the optimum deployment alternatives as the socioeconomic value is directly proportional to this variable. The flat nationwide fee of the mobile users means that the users are subsidised in sparsely populated areas – and overcharged in densely populated areas. This is the main reason why the commercial network seems to be most feasible in rural areas, whereas the dedicated network works best in urban areas. Based on the case study, the commercial network is most preferable up to the point when the population density reaches 50-125 persons/km². After that point, the dedicated network becomes more appropriate. Proposals are being made to improve the availability of the commercial networks enabling them to serve as a PPDR network: ensuring priority functionality and a protected power supply; allowing PPDR subscribers the exclusive use of one of the 700 MHz spectrum bands in restricted, critical areas; and extending use of the existing narrowband PPDR network in areas where communication availability is crucial.

On the one hand, the financing of BB PPDR mobile networks is an unresolved issue in many countries. On the other hand, the ability of commercial BB networks to provide better quality of service is improving, making viable the alternative to subscribe for radio service from a commercial operator. Therefore, the feasibility study on how to provide an optimum mobile BB service for PPDR organisations is of real value at this time.
