BACKGROUND AND OBJECTIVES: Small and medium enterprises still exhibit dominant contribution to the economy. Small and medium enterprises manage to absorb greater labor force and to survive the economic crisis. Various efforts to empower small and medium enterprises have been less successful. Financing constraint, low quality of human resources, and limited marketing competence have been the typical problems of small and medium enterprises that harm small and medium enterprises performance. Despite these problems, SMEs still manage to survive. METHODS: Using the sampling method of stratified random sampling with area strata, this study generates 203 small business units as the sample. The research was conducted by using accidental sampling. The quantitative and qualitative data are from primary and secondary sources. The data was collected by using observation, interview, and in-depth interview. The variables in this research was analyzed by using path analysis. FINDING: Social capital positively affect small and medium enterprises ’ financing as indicated by the significance value of 0.000 (< α= 5%). The stronger social capital of small and medium enterprises implied greater access of external financing sources. Social capital, and small and medium enterprises financing positively affect small and medium enterprises performance with 1% confidence level, and human resources positively affect small and medium enterprises performance with 6% confidence level. The finding shown the stronger social capital and human resources increases SMEs performance. CONCLUSION: The results show that social capital and SMEs’ financing positively affect SMEs’ performance, and human resources positively affect small and medium enterprises performance. The results imply that stronger social capital and human resources increases small and medium enterprises performance. Social capital facilitates access to finance, marketing, production, and information. The results shows that human resources affect SMEs’ performance. Social capital and human resources positively affect small and medium enterprises financing. Similarly, social capital, human resources, and financing positively affect SMEs’ performance.

BACKGROUND AND OBJECTIVES: Self-leadership is an uplifting concept in this technologically driven world. Given the potential benefits of self-leadership and its increasing popularity, it is surprising that self-leadership is an under-researched topic. The purpose of this study was to understand the personality factors related to the use of self-leadership behaviors.METHODS: This study analyzed data obtained from 217 respondents through an online survey. The study proposed model was tested using multiple regression to analyze individual characteristics of self-leaders and the results indicated that the model was partially supported.FINDINGS: The findings indicate that individual characteristics do predict self-leadership. Personality traits variables conscientiousness (beta = .32, p < .01) and openness (beta = .26, p < .05) have a significant positive relationship with self-leadership practices. Surprisingly, this study found emotional stability has no significant relationship with self-leadership behavior.CONCLUSION: The results of this study suggested that conscientiousness is important in the development of self-leadership meta-skills possibly through self-directed self-regulation and the practice of self-leadership. This study also employed a rigorous validation technique therefore, this study was able to address some of the methodological limitations of previous studies such as common method variance by examining the proposed relationships in a longitudinal setting.

BACKGROUND AND OBJECTIVES: Urban administrators of major cities in India are planning to deploy advanced information technologies such as artificial intelligence to deliver e-governance services. It is expected to enable citizens to acquire relevant information to their commonly asked questions without significant technological expertise. With its text, speech, and image processing capabilities similar to human beings, artificial intelligence is predicted to have both positive and negative social impact. The objective of this paper was to develop a conceptual framework consisting of enablers and barriers in adopting artificial intelligence enabled service delivery in a smart city from citizens’ perspectives. The study is novel in terms of empirically finding factors influencing adoption intention of artificial intelligence for availing citizen services in a nation like India which has a very large population and developing economy.METHODS: The study utilized an extended unified theory of acceptance and use of technology framework and employed survey-based data collection technique. A structured survey was circulated as part of primary data collection. The responses were collected from 772 sample respondents from three upcoming smart cities in India and were further examined by deploying the structural equation modeling technique using IBM SPSS and AMOS tools.FINDINGS: The proposed framework in this research study has social implications in terms of key factors that are critical when conceptualizing government services using artificial intelligence to avoid any harmful effects on society. The findings demonstrated six enablers and three barriers significantly affecting adoption intention (p<0.05) and explained 81 percent of the variance (R2) with the model's Goodness-of-fit index above 0.9. The quantitative results are also validated with the case studies from six smart cities across the globe for designing and deploying artificial intelligence-based services in the public sector. CONCLUSION: the study highlights that the smart city management must make sufficient effort to ensure that artificial intelligence service delivery in a smart city is equitable for all socioeconomic levels of city residents. The study provides several policy recommendations for governments and technology service providers when deploying artificial intelligence-based services for citizens in developing countries like India.

BACKGROUND AND OBJECTIVES: Environmental worry involve primarily the thoughts of some hazardous immediate and long-run side effects of degradation that happened to our ecological system. Despite the side effects of this phenomenon, psychometrics measuring environmental worry from the African context are insufficient. Therefore, the Environmental Worry Index (EWI-11) was developed to assess proximal and personal experiences of worry about climate change and environmental degradation. METHODS: This study used a qualitative method among environmental professionals and students (between the ages of 18 to 65) in a university to generate the themes and the pool of items that were used to determine the Environmental Worry Index (EWI-11). Thereafter, 925 participants were purposively selected and assessed from Ibadan city through a cross-sectional survey to ascertain the validity and reliability of this new scale. The participants were selected in Ibadan city, Nigeria. The software of the Statistical Package for Social Sciences (Version 26.0) was used for all analyses.FINDINGS: Using exploratory factor analysis, the construct validity and Varimax rotation showed that the scale has two components (KMO = 0.892, df=91, p.00), thus showing a strong validity. The reliability dimensions and subscales have meritorious reliability (Proximal, α =.894, and Personal experience of worry, α =.671). The overall Cronbach’s Alpha was 0.894.CONCLUSION: The EWI-11 is adequate for measuring environmental worry and could be useful for experts in mental and environmental research and practice. EWI-11 is therefore recommended as a reliable and valid screening tool for environmental worry and may be acceptable across Africa and other countries as well.

This study focused on the public transport risk assessment in District one of Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an effort to help urban managers to assess the risks in the public transport and prevent road accidents. Finally, the risk identification and assessment of public transport in District one yielded several results to answer the research questions. The hypotheses analysis suggested that safety issues involved in public transport are concerned by urban managers. The key reactive measures are investigation of accidents, identification of causes and correction of black spots. In addition to high costs, however, the reactive measures give rise to multiple operational problems such as traffic navigation and guaranteeing user safety in every operation. The case study highlighted the same fact. The macro-level management in the metropolis of Tehran is critical. The urban road casualties and losses can be curtailed by preventive measures such as continuous assessment of road safety.

Nowadays, it is vital to pay attention more seriously to the urban environmental risks because of its effects on citizens' lives. One of these problems is groundwater pollution which threatens much valuable water resources. Drinking water in Qom City is provided from different resources, such as watersheds and water wells which are located within the city. Although there is a shortage of water supply, according to the extreme water demand, these wells are used to provide city drinking water. Unfortunately, Sewage collection network in this city has not been completed yet and only a small amount of municipal wastewater is collected by the sewer network. As a result the city aquifer has been contaminated by the wastewater infiltration through the septic tanks scattered across the city. In order to assess the amount of contamination in water wells in urban areas of Qom City, sampling and testing of 24 deep wells which are scattered in the city was performed on December 2013. The meseared qualitative parameters consist of color, T, TU, TSS, pH, EC, TDS, DO, BOD5, COD, Total Alkalinity, CO3, HCO3, Total Hardness, Ca, Mg, SO4, Cl, Na, K, NH4, NO2, NO3, PO4, Br, I, TC, FC, FS, HPC, Fe, Hg, Pb, Co, Cd, Ni, As, Zn, B, Cu, Mn, Sn, Ba, and Sr. In this study, the drinking water physical, chemical and microbiological specifications guidelines of Iranian Standards and Industrial Research and the World Health Organization standards were used to evaluate the amount of the aquifer pollution. The results indicate that the aquifer in Qom is polluted widely by B, NO3, TC, FC and HPC.

Today, most countries in the world are gearing up by innovation, seeking to increase productivity and improve their economic situation, and one of the important centers for innovative activities is the incubator centered companies. The majority of companies based in incubator centers are startups companies. Considering that the failure rate of new firms in the early years of formation is greater, research should be conducted on the success factors of these companies. Therefore, the present study aims to identify the key factors for the success of knowledge-based companies Relied on academic incubator centers and it was carried out with the Meta synthesis method. Meta synthesis requires that the researcher carry out a thorough and in-depth review, combining the findings of relevant qualitative research. Using the Meta synthesis method, evaluated over 38 articles in the field of knowledge-based companies. Content mining was used to extract the dimensions and codes, and the significance and priority of each was determined by the use of the quantitative Shannon entropy method. 13 codes, 4 general concepts and 2 categories were identified by reviewing 38 articles. Shannon’s entropy was determined based on the results of the quantitative analysis. To evaluate the quality, the results are presented to one of the experts to be examined by the Kappa index Using SPSS software; a significant number of 0.000 and an index value of 0.706 were calculated. So it can be claimed that the extraction of the codes had a good reliability. The most important factor for the success of the companies located in the incubator centers of Sistan and Baluchistan University is the marketing and sales capabilities that have the highest coefficient and have the highest rankings in total. Based on the findings, it was found that the factors of marketing and sales capabilities, the presence of specialized staff and information technology related infrastructure (software, hardware, network, and brain ware), respectively, have the most impact on the success of knowledge-based companies Relied on university incubator centers.

Environmental pollutants have become a dreadful problem and burning issues for the present world irrespective of a country who is responsible for it. The objective of the study is to investigate impact of financial development and institutional quality on environmental degradation. The study is based on panel data for developing and developed countries over the time of 1996-2016. For the empirical analysis fixed effect and the random effect is carried out. Results show that institutional quality, economic growth, foreign direct investment, gross primary enrolment, and industrial growth have significant positive effect on corban emissions whereas financial development, population growth, trade openness, urban population and R&D expenditures have significant negative effect on corban emissions. One percent point increase in the index of institutional quality leads towards 0.006 percent points increase in the level of CO2 emissions. One percent point increase in the economic growth lead to increase the CO2 emissions by 0.39 percent points. One percent point increase in inflows of foreign direct investment increase the level of CO2 emissions by 0.016 percent points. One percent point increase in industrial growth leads to a 0.38 percent points increase in the level of CO2 emissions. Furthermore, one percent point increase in the index of financial development leads to 0.05 percent points decrease in the level of CO2 emissions. One percent point increase in urban population leads to almost 0.05 percent points fall in the level of CO2 emissions. Finally, one percent point rise in R&D expenditures leads to decrease in the level of CO2 emissions by 0.068 percent points.

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Microbial biomass C (Cmic) amounts ranged from 0.138 to 1.102 mg/g soils in the polluted sites and from 0.104 to 1.283 mg/g soils in the control area. Soils polluted with alkaline cement dust resulted in meaningful reduction in Cmic levels compared to control soils. Pearson correlation coefficients (r) show Cmic was positively correlated to soil CaCO3 content (r = 0.09). Cmic/Corg ratio was 2.54 and 1.92 in the control and cement polluted sites, respectively. Reduction in this ratio can be resulted from soil degradation in cement polluted soils. A significant decrease in the Cmic/Corg ratio in cement dust-polluted soils illustrated that this factor can be applied as a good indicator of soil quality. In the case of chlorophyll content of plant species, maximum reduction of total chlorophyll for Triticum aestivum L. was 45% compared to Hordeum vulgare L. with 60%. Therefore, results show higher sensitivity of H.vulgare than to T. aestivum.

In the current period, followed by the industrial revolution, the damaging effects of the one-dimensional attitude towards the environment caused by human have had countless hazards. To cope with these risks, the respect and protection of environmental values has attracted today's urban human attention once again and the issues about the human right to a decent, safe and healthy environment which is called briefly" environmental rights ", have widely been discussed. In fact, this research is formed on the basis of the principle that the right to a healthy environment, must be respected in the design of public spaces and the legal aspects of this principle must be considered in dealing with these spaces, so one of the necessary contexts to the conversion of today’s public spaces to valuable urban places would be provided. Therefore, in this study the human right to a healthy, safe and decent environment and the related concepts has been reviewed and the role of the environment in the process of transforming urban spaces to urban places has been discussed. This study also emphasizes on the role of the noise pollution of the urban public spaces as one of the threatening factors of the right to the environment, in the inefficiency and disorder in the process of the conversion of these spaces to public places and while reviewing the laws to reduce such pollution in urban public spaces, it stresses the necessity of considering these rules in designing the urban public spaces. This study uses descriptive and analytic research methodology and investigation techniques of literature review by using library studies.

Human Resource Architecture, one of the components of organizational architecture, is the process of identifying and combining the appropriate elements of human resource management to create and present a vision of human resources in the organization. Organization in which there is a coordination between employee behavior, human resource systems, resource activities, and the mission and goals of the organization. Governance is also an economic and political means of exercising power in a country's economic, political and social institutions, or as a set of traditions and institutions in which a sovereign operates, or for managing all relationships, and is defined as an executive term at all levels. The purpose of this study is to investigate the architectural performance of human resource management in municipalities.METHODS: This study is quantitative and developmental research. In this study, non-interactive method and thematic analysis of documents were used. Initially, 30 documents were identified and examined, and then the text reading table using the Scopus index identified 7 fully related documents. Next, three open, axial and selective encodings are performed on the specified documents. MAXQDA2020 software was used for data analysis. Then, to verify the validity of the identified components of the cryptographic output, its validation was performed using a distribution of 75 questionnaires among middle and senior managers of the Municipality of Tehran, using LISREL software.FINDINGS: Considering the coding, finally, human resource architecture with a governance approach in four dimensions (partnership and network governance; contractual and joint governance from above; outsourcing and job-oriented governance and hierarchical and knowledge-based governance) and 15 components of the category was classified. In partnership and network governance, the most repetition in component-related documents emphasizes on joined-up management (5 repetitions) and in contract and partnership governance, the most repetition is related to the commitment and accountability components (5 repetitions) and outsourced and job-oriented government with private component. (6 repetitions) and hierarchical and knowledge-based governance with an internalization component (4 repetitions). Based on the findings of confirmatory factor analysis, only the internalization component (T-Value <1.96) was not approved in the Municipality of Tehran.CONCLUSION: From the coding, it is finally concluded that the human resource architecture with a four-way governance approach of the partnership and network architecture; contractual and joint governance from above; Outsourcing and job-oriented architectures as well as hierarchical and knowledge-based architectures have the most iterations in the reviewed literature.

BACKGROUND AND OBJECTIVES: A relatively large number of historic (traditional and old) houses have been restored in Iranian cities in the recent period. Of increasing demand in the era of the experience economy, many are used as cafes, restaurants, galleries, ecolodges, etc. Cultural heritage and urban policies have further provided a general framework and some incentives for the restoration and reuse of these houses. Leveraging a tourism development framework, this paper investigated how authenticity could be achieved in practice in the restoration and reinvention of historic houses.METHODS: A flexible policy research approach was employed to probe the current framework governing the restoration of historic houses. Another part of the analysis was based on a set of semi-structured interviews and field observations targeting restored historic houses in the city of Shiraz. Specifically, interviews were conducted with owners/operators of the most significant category of reused old houses—those turned into ecolodges—along with visitors.FINDINGS: Based on the fieldwork results, five general recommendations were provided for owners/operators of restored historic houses/ecolodges toward realizing authenticity: there is a need for pre-planning and employment of adequate knowledge and knowhow to provide authentic experiences to visitors; objective elements should leverage creativity, balance tradition and modernity, and give the establishment its own personality; subjective elements should be reflective of local culture, history, and hospitality; a major aim is to have tourists emotionally engaged with the place and easily interact with people, places, and things; and allowing for co-creation could instill an enduring sense of belonging into visitors.CONCLUSION: Notwithstanding recommendations for owners/operators of restored historic houses, tourism and urban authorities must focus on the creation of a policy framework that encourages the delivery and management of authenticity. Adopting a stronger socio-cultural approach should help to achieve additional regeneration objectives of local economic development through increased interaction among public-sector agencies, non-governmental institutions, local populations (property-owners or tenants), and investors.

Integrating a geographic information system and multi-criteria decision making methods have been lead to provide spatial multi-criteria decision making methods. In this study, the spatial potential of flooding was determined based on analytic network process and analytic hierarchy process. At first, six factors of flooding were determined as criteria. The criteria were the slope, hill-slope aspect, curve number, snow, and rainfall on snow and land use. Also, 25 sub-criteria were determined for them. Then, the criteria and their sub-criteria were weighted based on the analytic network process and the analytic hierarchy process methods. In the next stage, were integrated the weights of the criteria and sub-criteria on their layers in the IlWIS 3 and were calculated the relative weighted average of flooding as the spatial potential of flooding. The results showed that analytic network process and the analytic hierarchy process methods have a high capability to estimate the potential of flooding. The analytic hierarchy process method had calculated the relative weighted average of flooding in the control and sample sub-catchments 26 and 23 percent, respectively. Also, the analytic network process method had calculated it 25 and 21 percent. Based on the results, the both methods have the same capability to estimate the potential of flooding, but for comparison of sub-catchments, the analytic hierarchy process method is recommended, whereas the analytic network process method is recommended for studying one sub-catchment and spatial variations of flooding. Moreover, the analytic hierarchy process method is simpler than analytic network process method to estimate the potential of flooding.

Climate displaced persons generally follow the same trails as other migrants, but climate-induced displacement is adding to the pace and scale of human mobility. The prime aim of the study was to investigate the rural to urban migration of climate induced displacement in coastal area of Bangladesh addressing to risks and opportunities. The study mainly based on primary data and secondary data was used for validation. The study reveals that after displacement nearly 89% displaced people migrated from rural (Kutubdia Island) to Cox’s Bazar urban area. Consequently, meantime their monthly income, occupational status, housing and sanitation condition, source of drinking water and health care facilities were changed positively but in most cases they are dissatisfied. Because they lost their traditional and indigenous occupations system and their housing pattern and conditions become worsen. Availability of water and sanitation facility and healthcare seeking behavior changed positively in the urban area. Finally, the study revealed that there is risk and opportunity for climate displaced people in urban migration. However, planned/fair migration of climate displaced people can reduce the risk factors in the urban setting.

BACKGROUND AND OBJECTIVES: The Bangladesh government declared a general holiday beginning on March 26, 2020 aimed to combat coronavirus (COVID-19) pandemic. The aim of this study was to assess the impacts of the general holiday on air quality in Dhaka city area of Bangladesh. METHODS: Hourly PM2.5 (aerodynamic diameter ≤2.5 µm) data was collected from publicly available World's Air Pollution: Real-time Air Quality Index Project from March 1 to May 16 for the five years 2016 to 2020. Tukey Multiple Comparison test was conducted to address the observable level of air quality changes between the years. Additionally, Moderate Resolution Imaging Spectroradiometer using the Aerosol Optical Depth with 550nm wavelength was analyzed during the same time period. FINDING: This Study found that, between April 7 and May 16, the mean daily reading of PM2.5 was less in 2020 when compared to previous years. The mean hourly reported PM2.5 during working hours of 6AM and 8 PM for 2020 was statistically lower (at α= 0.01 level) than all other years 2019, 2018, 2017 and 2016. The mean hourly reported PM2.5 for 2019 was statistically higher (at α = 0.01 level) than all other years 2020, 2018, 2017, and 2016. The Bus Rapid Transit and Mass Rapid Transit Construction in 2019 contributed between 24.2% and 38.6% of the PM2.5 dust during this period. The elimination of diesel bus traffic during working hours in 2020 reduced the dust levels between 15.9% and 36.3% compared to the previous four years. A declining trend of AOD550 values was observed from April 7 to May 16, 2020 compared to previous four years (2016-2019). CONCLUSION: During the general holiday period in Dhaka, the daily and working hour PM2.5 as well as daily Aerosol Optical Depth were reduced compared to previous four years (2016-2019). Government action is recommended to reduce dust created during major construction projects. It is recommended the government authorize the replacement of buses with less polluting vehicles.

BACKGROUND AND OBJECTIVES: Urban ecosystem services are provided by a multitude of habitats, including green and water spaces. Such services are commonly under the control of heavy demand raised by the large number of beneficiaries. In this context, urban green spaces viz. parks and gardens supply these services for city residents. From this perspective, this study is to analyze the spatiotemporal changes in the ecosystem servicevalue of urban green spaces in Districts 1 and 14 (out of 22) of Tehran Municipality, Tehran, Iran. The level of resilience (namely, capacity and adaptability) of these districts, once confronted with climate change and environmental degradation, particularly carbon sequestration, is then investigated. As an innovation, the current study ultimately assesses the ecosystem services value of urban green spaces with higher accuracy to exert more actions to improve these spaces.METHODS: This library-based documentation study utilized spatiotemporal modeling with reference to software packages and field visits. In the first step, remote sensing was applied to create land-use maps using ENVI 5.3 software package and its formulas, algorithms, and extensions. In the second step, the InVEST software and model were used to model carbon sequestration in selected districts. To assess carbon sequestration and its changes over time, land-cover maps were generated for three 10-year periods (2003, 2013, and 2023) with 30 m accuracy via Landsat satellite-based program. The maps were classified in ENVI 5.3, and the net carbon sequestration in land, along with the market size of carbon sequestration, was estimated using the InVEST model, incorporating land-use maps, land-cover types, and carbon sequestration in reservoirs. Organic carbon content was determined based on other carbon reservoirs, previous surveys, and available data. Each carbon reservoir unit was valued in dollars, and discount rates and annual changes in carbon value were calculated based on global and local conditions surveys.RESULTS: The study results obtained from land-cover/use maps produced during 2003, 2013, and 2023 in the selected districts, demonstrated a diminishing trend of green spaces and barren lands, while the area of built land has increased over time. The numerous changes in land use in the company of construction in green spaces and barren lands in District 1 from 2003 to 2013 had further led to 191401608 tons of emission, including 179114669 tons of carbon, valued 49056267 and 4636422 million Dollars, respectively. In District 14, the emission during 2003-2023 was also equal to 18.3644 tons of carbon, and that was 3444.14 tons of carbon for the period of 2013-2023, worth 1873871 and 1749769 thousand Dollars, in that order.CONCLUSION: Indiscriminate construction and development of built-up areas in Tehran have undermined green spaces and barren lands, negating the benefits of green infrastructure efforts. This has resulted in a reduction in urban green spaces, hampering their capacity for carbon absorption and sequestration. Consequently, reduced carbon deposition will contribute to higher temperatures, diminishing the resilience of these urban areas.

BACKGROUND AND OBJECTIVES: Social resilience is one of the ways to reduce social problems and is a factor for the success of social welfare programs, increasing trust and social capital; therefore, in recent years, more attention has been paid to the issue of social resilience. The present study deals with theoretical and experimental analysis of social resilience. METHODS: The aim of this study was to investigate the level of social resilience in region one of Karaj city by descriptive-analytical method. The statistical population consisted of residents of District one of Karaj city, 384 of whom were randomly selected. The researcher-made questionnaire was confirmed by face validity and Cronbach's alpha of 0.85. FINDING: Data analysis was performed using descriptive and inferential statistics in SPSS software. The results showed that the confidence component was 2.53, 1.73, 2.52, 4.14, 4.01 and 8.86 that all coefficients were higher than 2.59 at the significance level of 0.01. For the social capital component was 1.65, 6.14, 07.03, -1.01, and -0.35, which showed that all coefficients were higher than 2.59 (14, 15) at the significance level of 0.01. For the component of commonalities between residents component was 7.87, 11.74, 7.21, 0.85-1.17, 2.93, showing that all coefficients were higher than 2.59 at the significance level of 0.01. Also, the structural model of social cohesion, the criteria of goodness of fit index and the adjusted fit index were equal to 0.79, which indicates that the model has a moderate fit. CONCLUSION:The purpose of this study was to investigate and measure the criteria of social resilience among the four dimensions of resilience in the settlement. As one of the most important ideas in urban planning is to create resilient cities that are resilient to social crises, therefore, paying attention to the dimensions of social cohesion, including: trust, social capital and commonalities between residents can ensure that a high level of social resilience is created and effectively operates in accordance with sustainability in society.

Environmental impacts assessment may be some measures to offset the impact to an acceptable level or explore new solutions. The research was conducted with the aim of assessing the socio-economic, cultural, physical and ecological impacts of Kavar irrigation and drainage network in Fars Province (Iran). In this study, Environmental impacts assessment was undertaken by ICOLD matrix. The ICOLD matrix is one of the flexible methods that converted qualitative data into quantitative data. In this method, the effect of the project activities on the environmental components were assessed in two stages; project construction and operation based on physical, ecological, socio-economic and cultural aspects. The findings indicated that positive effects will be generally exerted on the region environment by establishing and operating irrigation and drainage network in Kavar plain. In other words, substantial positive impacts will be seen in the region consequently; such as improving the average level of aquifer, enhancement of agricultural wells, and agriculture development in the region. However, in order to alleviate the negative impacts of the projects processes, it is suggested that presented environmental training to farmers, collaborating and further communicating with other relevant organizations and institutions.

The social dynamics of cities have long been dependent on their spaces and places. On the one hand, human interactions, and relationships are formed by the city form and on the other hand, the body recovers its identity from existing social life. The more a city can communicate with its citizens through physical features, the more it will affect their social identity. Thus, the city form can have a considerable effect on the relationships and social capital among humans. Karaj city is the second immigrant city because of being close to Tehran Capital of Iran. Nowadays, the slumming phenomenon in Karaj has become a fundamental problem that the physical distinctions of the slum districts seem to have led to a change in the social capacities of the district. Based on the survey and using processed data extracted from the questionnaire in a quantitative model through SPSS software, physical characteristics and architectural spaces of Zurabad neighborhood of Karaj contribute to the decline in social capital of the people in this neighborhood to 79%, resulting from reducing people's trust in the neighborhood up to 84%, its people’s security up to 85%, its people’s sense of belonging up to 72% and in its people’s participation up to 75%. These results indicate the urgent need for immediate attention to the body and context of this region that shapes each individual's social and individual identity over time.

In a new era, the organizational climate has built as the norms, values, beliefs, traditions, and ceremonies where people work together to solve problems and face challenges. This study was to determine whether there is a relationship between each of the three dimensions of organizational climate (supervisory support, autonomy, and goal direction) and Organizational Citizenship Behavior-Individual and Organizational Citizenship Behavior-Organizational on a non-supervisory staff of Bank Simpanan National in Malaysia. Nevertheless, the framework of this study was discussed based on the suitable underpinning theory of organizational climate and how the organizational climate theory relates to organizational citizenship behavior. The population of employees in Bank Simpanan National was 7,000. Samples taken amounted to 99 (Male=52; Female=47) of the non-supervisory staff, respondents of the total population of 7,000, through sampling techniques, namely purposive sampling. Respondents' were selected among non-supervisory employees in this study. This study was examined using the quantitative method. In this study data analysis is done by IBM Statistical Product and Service Solution (SPSS) program for windows version 22. Data collection techniques used the form of a 7-Likert scale of organizational climate and organizational citizenship behavior. It was examined using correlation analysis. This study revealed a significant association between organizational climate and organizational citizenship behavior on non-supervisory employees of Bank Simpanan National in Malaysia.

BACKGROUND AND OBJECTIVES: Climate change is one of the existential threats of modern times, which deserves urgent attention by policymakers. The objective of this paper is to comprehend the impact of climate change on the Gambian economy both in the short and long-run. METHODS: This paper analyses time series data from 1969 to 2016. The study incorporated rainfall and temperature as proxies of climate change into the Cobb-Douglas production function. The Augmented Dickey-Fuller and the Phillips-Perron stationarity test for unit root found that the growth rate of rainfall is not statistically significant with the Mackinnon approximate p-value for z (t) =0.2306. The first lag is significant at 5% and 10% but has a negative coefficient in the first differential up to the fourth lag. In contrast, the growth rate of temperature is statistically significant with a p-value of 0.0196. FINDING: The findings revealed that human capital growth is not significantly related to economic growth in The Gambia. In the long-run, the growth rates of climate change variables are all statistically significant and associated with a negative impact on economic growth. For the short-run, the lag difference of rainfall against its own lag is statistically significant and has a positive impact on economic growth. The lag difference in the growth rate of the Gross Domestic Product is not statistically significantly related to the growth rate of rainfall. CONCLUSION: The Gambia is vulnerable to climate change shocks, consequently climate change will negatively impact economic growth resulting in high unemployment, low productivity, and high poverty rate.

BACKGROUND AND OBJECTIVES: Leadership styles will have different effects on company performance, so many literatures in China study the relationship between leadership styles and company performance in manufacturing. The purpose of this study is to investigate the relationship between leadership styles and company performance in Chinese manufacturing. As a result of ineffective management in leading employees, China is currently experiencing poor financial and marketing performance, which has resulted in poor business operations and lower productivity, both of which have a direct impact on the company's performance in China's manufacturing industry.METHODS: This study adopts quantitative research method to collect data of factors affecting company performance through questionnaires, the sampling technique is snowball sampling. A total of 450 questionnaires were sent out to the respondents, and a total of 384 questionnaires were returned. Among them, 290 questionnaires were usable. A preliminary study was conducted to ensure that the adjusted questionnaire items were appropriate and valid for the study. In actual data collection, 290 responses were successfully collected in this study, with a response rate of 65%. The SPSS software was utilized to analyze the data in this study.FINDINGS: Based on the quantitative data analysis, the findings found that dictatorial leadership style paternalistic leadership style, autocratic leadership style, and laissez-faire leadership style insignificantly correlated with company performance in China. Democratic leadership style significantly correlated with company performance in China. Further, research findings have been discussed in the discussion of results.CONCLUSION: These findings may provide the purpose of this study that characterize company performance, confirm leadership style in the Chinese manufacturing sector, and apply performance theory to further analyze the effect of leadership style. The Tannenbaum and Schmidt leadership styles should suggest that leadership behaviour varies along a continuum, with a level of follower participation and involvement in decision-making growing as leaders move away from the authoritarian extreme.
