Among the various abiotic stresses, drought is the major factor limiting crop productivity worldwide. Citrus has been recognized as a fruit tree crop group of great importance to the global agricultural sector since there are 140 citrus-producing countries worldwide. The majority of citrus-producing areas are subjected to dry and hot summer weather, limited availability of water resources with parallel low-quality irrigation water due to increased salinity regimes. Citrus trees are generally classified as “salt-intolerant” with high water needs, especially during summer. Water scarcity negatively affects plant growth and impairs cell metabolism, affecting the overall tree growth and the quality of produced fruit. Key factors that overall attempt to sustain and withstand the negative effect of salinity and drought stress are the extensive use of rootstocks in citriculture as well as the appropriate agronomical and irrigation practices applied. This review paper emphasizes and summarizes the crucial role of the above factors in the sustainability of citriculture.

In this study, we explore whether microfinance institutions (MFIs) can mitigate the adverse macroeconomic consequences of natural disasters. The provision of capital immediately following a natural event is recognized as one of the necessary conditions for a fast economic recovery. However, one concern is that a large majority of natural disasters occur in developing countries where households and the private sector have only limited access to the formal banking system. As an alternative, MFIs may fill up this gap in providing liquidity in the form of microcredit. The existing evidence on how MFIs respond to disaster effects is foremost based on case and micro-level evidence. In turn, the focus of this study is more on the macro impact of MFI activities after a natural disaster. Based on the finding obtained from an OLS-FE model using an unbalanced panel considering more than 80 developing countries and emerging economies, we can conclude that natural disasters harm macroeconomic performance primarily through their effect on the agricultural sector. However, access to lending facilities from MFIs mitigates a large part of this negative effect. Moreover, the extent to which MFIs are able to mitigate these effects depends to a great extent on their nature, i.e., their organizational structure, profitability, legal status, age, and the number of clients they serve.

The aim of this study is to understand the perspective of elderly residents on their neighborhood and how the composition of the neighborhood influences their daily life. The study took place in the city of Cáceres (Spain) that aspires to become an age-friendly city. This study focused on the intangible elements of the neighborhood related to feelings of safety, well-being, loneliness, belonging to the community and development of trusting relationships. The research was based on the sociology of aging, specifically referencing the theory of the activity of aging, and also urban sociology, which assumes the environment as a conditioning agent of daily life. Using a qualitative approach, 32 in-depth interviews were conducted with individuals over 65. The interviews were analyzed according to grounded theory. The results show how social aspects are key factors for the elderly in their perception of the neighborhood. Therefore, psychological, social and emotional dimensions of the neighborhood influence elderly residents and could have a positive or negative effect on successful aging. These findings also suggest that a crucial aspect of the positive perceptions of the environment lies in the quality of social interactions that take place inside the neighborhood.


The potential of ICTs in promoting the development and reach of educational avenues in India is unambiguously clear in the light of the challenges facing the country. Role of ICTs with enhanced focus on development of content and the applications to provide enhanced quality of education must be synchronized with the various initiatives for using ICT for education and should be guided by adequate guidelines and framework. Provisioning of ICT is limited by the Infrastructure especially in the rural areas, where Internet and electrification are major issues of concern. It is well known that higher penetration of mobile phone, radio and TV implies increased development and delivery of innovative content via these media.

Egyptian urban spaces suffer from a chaos that is the result of crowded and disordered pedestrian sidewalks, streets and shop signage. This chaos creates a negative effect on, both, the image of the city and the quality of life within these urban spaces. Many legislations and regulations in Egypt attempted to deal with these issues. Similarly, the Egyptian government established many organizations and authorities in order to deal with these issues with little success. The National Organization of Urban Harmony (NOUH) is one of those organizations established by the government to take the responsibility of dealing with pedestrian sidewalk and shops’ signage while the municipality deals with road occupations. These organizations should perform their responsibilities through the Egyptian legislations. The research at hand aims to find a solution to that particular problem which has influenced the quality of the street and its reflection to the quality of life as result. In order to find a solution, the research attempts to find a mechanism to boost the role of shop signage as an element of urban spaces in order to emphasize street quality. Thus, the research well be divided into four parts: part one reviews the quality of urban spaces and the meaning of its terms while part two reviews the concept of the quality of life and the relation between the quality of life and urban spaces. Part three demonstrates the urban quality of life through tangible and intangible approaches. Finally, part four reviews the Egyptian legislations that deal with research issues and attempts to find the difficulties that faced when enforcing laws. Finally, the research conclusion illustrates the most important issues in the research and their proposed solutions.

Suppose the agricultural sector is supported by a comprehensive and sustainable planning system and balanced with an adequate budget (such as capital). In that case, the role of the agricultural sector will be optimal. Farmers face the problem of funding; although many farmers can increase their yields, they cannot develop their own farming business if they do not have sufficient funds. Therefore, farmers will apply for loans from formal and informal financial institutions to overcome the lack of funds. However, credit growth has increased, especially in the agricultural sector, which is the agricultural sector where the government plans to improve the rural economy. Agricultural credit plays a crucial role in developing agriculture to obtain higher yields. If output increases, farmers' income will also increase, which will benefit farmers. The research method used was quantitative, with a sample of 100 people. This study used a population of 187 farmers in Kedung Lengkong Village, Dlangu District, Mojokerto Regency. The analysis used in this study was simple regression to understand the impact of credit availability on farmers' welfare. The hypothesis test results were that credit has a positive effect on welfare, with a regression coefficient value of 0.291. Credit helped farmers purchase fertilizers, seeds, and other things related to the need for farming so that the agricultural production process could run according to planning so that production results were in line with farmers' expectations to increase profits. These profits, in the end, became a source to meet the costs of meeting basic needs. The ability to meet these needs raised the standard of living and the community's welfare so that people could have a better quality of life.

Introduction This study investigates the extent to which Ontario hospital librarians and library resources support researchers and describe the librarians' participation in research capacity building within their institutions. Methods A 16-question SurveyMonkey™ web-based survey questionnaire was disseminated via email to 53 potential participants consisted of library directors, managers and solo librarians.  Results The response rate was 60%. The number of researchers supported by librarians ranged from 10 or less to 76 or more researchers in the past 10 months. Librarians supported a variety of scholarly research outputs, assisting researchers with journal articles being the most frequently supported activity.  The top three library resources used to support researchers were licensed electronic journals, print collections and expert librarian searches. One of the reported ways librarians received training to better assist researchers was via online continuing education.Discussion As others have reported, there was a predominance of support for literature studies including literature reviews and systematic reviews. Surprisingly, some librarians reported that they had all the databases or resources they needed to support research, while an alarming 79 per cent of respondents reported not having access to all the databases and resources they needed.  Lack of access to databases or online resources may have a negative effect on the quality of research the librarians provided. Raising the awareness of the role of the librarian in supporting researchers in the hospital setting can inform the health sciences librarians' professional practices and provide evidence of the library's participation in the research capacity building of the organization.

This article studies some aspects of the internationalization strategy of family SMEs. After examining the various problems facing family SMEs as regards internationalization, in terms of lack of resources, some mechanisms are discussed to counteract their negative effect. Using a wide sample of Spanish SMEs, we confirm the existence of a negative relationship between family ownership and internationalization, measured by export activities. We also analyze the role of generational changeovers and stable relationships with other firms through shareholding or agreements aimed to promote international expansion. These mechanisms are set out to provide family SMEs with the necessary resources that have proved to be key factors in a successful internationalization process.

The context of China fosters different contextual factors, which influences the quality of corporate social responsibility (CSR) disclosure in comparison to firms across the rest of the world. Political ties at a corporate level are one of these vital factors. This paper studies the influence of firm-level political ties (PT) and executive turnover (ET) on the quality of CSR disclosure in the context of shareholding status of departing executive in Chinese listed A-share firms. Stakeholder and Agency theories are applied to the dissemination of CSR disclosures in Chinese firms whereby we used 20,578 firm-years interpretations of Chinese registered companies between 2012 and 2019. The results foster a negative link between executive turnover and quality of CSR disclosures. In addition, a negative relationship has been found between political ties and the quality of CSR disclosure. The findings disclose that the shareholding status of departing executive moderate the relationship between the impact of political ties and executive turnover on firms quality of CSR disclosure, whilst the effect of executive turnover on the quality of CSR disclosure was found more pronounced for firms whose departing executive held larger shareholding (SH). This study contributed to the literature on the quality of CSR disclosure while recognizing the negative effect of executive turnover on a firm’s quality of CSR disclosure for politically tied firms with a reinforcing moderating role of the shareholding status of departing executive.
