Air Pollution Damage

Developing a regional power system to achieve a high level of integration of national systems requires sufficient development of the regional transmission grid. This is possible only with appropriate schemes for the complete cost–benefit analyses, and cost allocation of these transmission investments, which plays a critical role in the selection of the most efficient network investment and the proper assignment of their cost to the national systems. Network reinforcements affect the operation of power systems and, therefore, the externalities of power generation. This paper examines the impacts of integrating local air pollution damage from power production within the benefit assessment and cost allocation of transmission investments. The paper describes the methodology followed and illustrates its application in a real-life case study where a simplified version of a European network is considered. Within this case study, we have assessed the impact of considering the reduction in air pollution damage achieved through a particular HVDC project between France and Spain on the benefits, and benefit-driven cost allocation, computed for this project. In this case study, local pollution related benefits are a relevant fraction of the overall benefits of the considered transmission project. However, considering the local air pollution benefits of the project does not affect the net positive benefits of each country significantly, resulting in a limited change in the cost allocation of the project.

The Impact

Co-production is a solution by which the government provides public services. Co-production theory is built upon Western experience and currently focuses on the types of co-production in different policy stages, the barriers and governance strategies for co-production. However, little attention is paid to how political background will influence the co-production process. To fill the gap, we analyzed a case of co-production that occurred in China, and we characterized the political background as consisting of three main political features: political mobility, central–local relations, and performance measurement. Based on an in-depth case study of a government project in a medium-sized Chinese city, the impact and the changes of political features affecting governmental projects in different co-production stages are analyzed and assessed. We find that political features play a critical role in the co-production of China’s large government projects and may separately and jointly affect co-production. Government performance measurement affects the co-design and co-implementation of projects. Political mobility and changes in local government and performance measurement also affect the co-implementation continuity of the project. Political focus affects the co-design of projects. Central-local relations influence the support from higher government and the actual practices of lower government in the co-implementation stage.

Practical Implications

PurposeUsing the campus of a Brazilian university as case study, this research aims to identify which aspects of the outdoor spaces are the most significant in attracting people.Design/methodology/approachThis research relies on the application of different post-occupancy evaluation (POE) methods, including user tracking, behavioural mapping and questionnaires, on one plateau of the campus.FindingsThree group of aspects (socialization, proximity and infrastructure) were identified as key elements in explaining the impact of the campus physical characteristics on users’ behaviour. The results indicate that having characteristics of at least one group of aspects in those spaces can guarantee their vitality and, if there is presence of attributes of more than one group, liveliness can be increased.Research limitations/implicationsFurther studies should be conducted on an entire campus to identify other spatial elements in the three groups.Practical implicationsThis research contributes to the planning of future campuses and to solutions to the existed ones, indicating the most relevant spatial characteristics to be considered. Additionally, the combination of different methods may be useful to future research.Originality/valueMost of the investigations on the university campuses focus on the buildings, and little research has investigated the outdoor spaces, although they play a critical role in learning and academic life, where people establish social, cultural and personal relationships. In addition, studies using several POE allowed a consistent and complete diagnostic about the aspects of the campus, giving recommendations for future projects.

Abstract. Black carbon (BC) has been identified to play a critical role in aerosol-planet boundary layer (PBL) interaction and further deterioration of near-surface air pollution in megacities, which has been named as its dome effect. However, the impacts of key factors that influence this effect, such as the vertical distribution and aging processes of BC, and also the underlying land surface, have not been quantitatively explored yet. Here, based on available in-situ measurements of meteorology and atmospheric aerosols together with the meteorology-chemistry online coupled model, WRF-Chem, we conduct a set of parallel simulations to quantify the roles of these factors in influencing the BC's dome effect and surface haze pollution, and discuss the main implications of the results to air pollution mitigation in China. We found that the impact of BC on PBL is very sensitive to the altitude of aerosol layer. The upper level BC, especially those near the capping inversion, is more essential in suppressing the PBL height and weakening the turbulence mixing. The dome effect of BC tends to be significantly intensified as BC aerosol mixed with scattering aerosols during winter haze events, resulting in a decrease of PBL height by more than 25 %. In addition, the dome effect is more substantial (up to 15 %) in rural areas than that in the urban areas with the same BC loading, indicating an unexpected regional impact of such kind of effect to air quality in countryside. This study suggests that China's regional air pollution would greatly benefit from BC emission reductions, especially those from the elevated sources from the chimneys and also the domestic combustions in rural areas, through weakening the aerosol-boundary layer interactions that triggered by BC.

Interpersonal Competencies

Orientation: Regardless of the contribution done by small and medium-sized enterprises (SMEs) in modern economies, and the critical role managerial interpersonal competencies play in sustaining these enterprises, no known comparative study has been conducted in SMEs in developing economies.Research purpose: This study purposed to establish the impact of managerial interpersonal competencies on SME performance as measured by innovation and return on investment (ROI) in both family-owned SMEs (FOSMEs) and non-family-owned SMEs (NFOSMEs) in Zimbabwe and South Africa.Motivations for the study: Efforts at understanding managerial competencies and firm performance among SMEs have taken a holistic approach, using all known managerial competencies; yet, recently, there is acknowledgement that interpersonal competencies are more effective in business sustainability than other competencies. With this observation, the need to extent this finding in other contexts among FOSMEs and NFOSMEs in developing countries becomes apparent.Research approach/design and method: The study whose design was a descriptive comparative case study adopted a quantitative approach.Main findings: The study found a positive and significant relationship between managerial interpersonal competencies and firm performance as measured by innovation and ROI in FOSMEs in both countries.Practical/managerial implications: NFOSMEs may need to focus their training on interpersonal competencies for managers in order to be sustainable. For FOSMEs, continuous enhancement of managerial interpersonal competencies is important as it promotes innovation and business sustainability.Contribution/value-add: The study helps fill the lacuna between research and practice with respect to managerial interpersonal competencies in FOSMEs and NFOSMEs in the two countries.
