Abstract

This paper presents part of the results of ongoing integrated and interdisciplinary studies conducted at a vulnerable coastal lagoon system with the aim of protecting it from further anthropogenic pollution. The target area is in southwestern Turkey, consisting of a lake that joins the Mediterranean Sea via a lagoon channel system. Land resources in the watershed are identified, including all the elements of the physical environment that influence potential land‐use, and are illustrated by the application of geographical information systems through mapping and visualization of various thematic layers of land. This study will enlighten those working on lagoon watersheds aiming at conservation of natural resources since it states the results of the studies conducted so far through various disciplines, and presents how data are utilized by the groups in an integrated manner. Based on the available data, pre‐modelling studies on hydrodynamic modelling and on water quality modelling are also referred. Identification of a watershed depends on gathering satisfactory data, which will further be used to establish sustainable development and management plans, apart from utilizing the obtained data for watershed and hydrodynamic modelling approaches and to better understand such complex systems.

Abstract

Ömerli reservoir is the major reservoir of Istanbul in terms of water supply potential. However, rapid population increase, unplanned and illegal housing, irrelevant industries and motorways passing through the protection zones of the catchment area, together with insufficient infrastructure, cause the water quality of the reservoir to tend towards the eutrophic stage from the mesotrophic stage parallel to the land use profile. In order to achieve a long‐term water supply from the reservoir and to arrive at sanitary solutions, new land use plans should be developed. Therefore, the key idea of this paper is to develop a convenient protection strategy to keep the reservoir from further deterioration, in light of the guidelines of a new land use plan, and to allow the watershed to be used in accordance with the tendencies of society in a controlled manner, so as to maintain the sustainability of the reservoir for drinking water supply and to assure continuing control by implementing economic sanctions.

Abstract

Purpose

Rough estimations of water gain through greywater reuse and rainwater harvesting together with energy recovery from wastewater generated from a fictitious eco-city of population 100,000 located in Istanbul, Turkey form the main framework of the study. As such, the highly important concept of water–energy nexus will be emphasised and domestic wastewater will be partly considered for water recycling and the rest for energy recovery. The paper aims to discuss these issues.

Design/methodology/approach

Distribution of daily domestic water consumption among different household uses and the population in the residential area are the two governing parameters in the practical calculation of daily wastewater generated. Therefore, domestic wastewater will be initially estimated based on population, and in turn, the amount of greywater will be found from the per cent distribution of water use. After segregation of greywater, the energy equivalency of the rest of the wastewater, known as blackwater, will further be calculated. Besides, the long-term average precipitation data of the geographical location (Istanbul) are used in determining safe and sound rainwater harvesting. Harvesting is considered to be only from the roofs of the houses; therefore, surface area of the roofs is directly taken from an actual residential site in Turkey, housing the same population which is constructed in four stages. Similarly, the fictitious eco-city in Istanbul is assumed to be constructed in a stage-wise manner to resemble real conditions.

Findings

The water consumption of the fictitious eco-city ABC is considered as 15,000 m3/day by taking the unit water consumption 150 L/capita.day. Therefore, total water savings through on-site reuse and reuse as irrigation water (9,963 m3/day) will reduce water consumption by 64 per cent. Minimum 40 per cent water saving is shown to be possible by means of only greywater recycling and rainwater harvesting with a long-term average annual precipitation of 800 mm. The energy recovery from the rest of the wastewater after segregation of greywater is calculated as 15 MWh/day as electricity and heat that roughly correspond to electricity demand of 1,300 households each bearing four people.

Research limitations/implications

A fictitious eco-city rather than an actual one located in Istanbul is considered as the pilot area in the study. So far, an eco-city with population around 100,000 in Turkey does not exist. An important implication relates to rainwater harvesting. The amount of safe water to be gained through precipitation is subject to fluctuations within years and, thus, the amount of collected rainwater will highly depend on the geographical location of such an eco-city.

Practical implications

The study covering rough calculations on water savings and energy recovery from domestic wastewater will act as a guide to practitioners working on efficient water management in the eco-cities, especially in those that are planned in a developing country.

Originality/value

Practising water–energy nexus in an eco-city of population 100,000 regarding water savings and energy recovery from wastewater forms the originality of the study. Sustainable water use and energy recovery from wastewater are among the emerging topics in environmental science and technology. However, safe and sound applications are lacking especially in the developing countries. Guiding these countries with practical calculations on both water gain and energy recovery from wastewater (blackwater) is the value of the work done. Moreover, Istanbul is deliberately selected as a case study area for various reasons: its annual rainfall represents the worlds’ average, it is one of the most crowded megacities of the world that supply water demand from the surface water reservoirs and the megacity has not yet significantly increased wastewater reuse and recycling practices.

Abstract

Purpose

The purpose of this paper is to examine gender issues in Brazil from the perceptions, experiences, and discourses of professional women in Rio de Janeiro and São Paulo.

Design/methodology/approach

The study is based on 26 in-depth interviews with female professionals. The methodology consists of an exploratory approach through content analysis.

Findings

Despite the fact that Brazil demonstrates an idealized national ethos that promotes equality, gender roles are still very traditional. Participants recognized gender issues at work, including covert discrimination, though most did not acknowledge experiencing them personally.

Originality/value

There is dissonance between global trends and the actual experience of female professionals in Brazil. Although participants rejected the idea of personally experiencing inequality, they acknowledge its existence in human resources (HR) practices. This leads to a self-fulfilling prophecy where gender inequality is perpetuated and organizations and HR departments do not seem to have a proactive role as change agents.

Abstract

Purpose

The purpose of this paper is to carry out a quali-quantitative study to analyze unease and perceived stress in a population of 485 male and female police officers in a large city in northern Italy, and investigate the consequences of these and the coping strategies adopted. The working context the paper chose to investigate was the Municipal Police, which is characterized by strong links with the local community. As suggested in the literature, the paper focalized the attention both on organizational and operational stressors.

Design/methodology/approach

Quali-quantitative study: a self-administered questionnaire.

Findings

Results show that both men and women are self-critical and their evaluation of the professional and contextual circumstances in which they operate is filtered by pessimism and self-blame, with higher levels of somatization in women: female patrol police officers are at the highest risk of psychological distress.

Originality/value

This is, to the best of the knowledge, the first quali-quantities study in Italy to consider the gender variable within a single police force.

Abstract

The serendipitous beginning and organic evolvement of the Dragon Research Collaborative (DRC) allowed us the freedom to approach the learning environment differently than we had in prior, more traditional projects or courses. We embrace that freedom in the project’s structure. For us, dragons are the catalyst for construction of an educational environment that encompasses science, social science, the humanities, and the fine arts, but not solely within a school context. The partners that have joined with us, museums, businesses, and other higher education staff and faculty, are integral to establishing the real-world authenticity of the DRC. We share here the strategies and tools we have found useful in creating synergistic, multidisciplinary learning opportunities. The DRC model’s strength lies in several characteristics: a collaborative, caring environment, knowledge construction that is student-driven, and a robust partner network.

Abstract

Leadership has been an active area of research and practice in China over the past 30 years of economic reform and organizational change. The main purpose of this chapter is to summarize recent progress from leadership research in China and to propose a growth model for Chinese change leadership. There have been three key trends emerging from the recent research and applications under organizational change in China: (1) problem-driven trend emphasizing global leadership context and business practices; (2) high-performance human resources configuration trend integrating key competencies to build up the new work systems for global leadership; and (3) theory-building trend focusing upon the conceptual development for global leadership areas for future research and applications in China. These trends are discussed in connection with organizational change and global entrepreneurship. The recent progresses in leadership research and practice in China indicated that leadership development has become more and more strategic and embedded with the cultural and industrial contexts. A theory of “adaptation-selection-development” (ASD) is proposed for more systematic research and theory development in global leadership research and applications in China. This chapter demonstrates frontier approaches and implications of the ASD framework for global leadership development are highlighted.

Abstract

Purpose

Sustainability involves ensuring that sufficient resources are available for current and future generations. Non-revenue water (NRW) creates a barrier to sustainability through energy and water loss. However, a comprehensive overview of NRW reduction strategies is lacking. This study reviews the existing literature to identify available strategies for reducing NRW and its components and discusses their merits.

Design/methodology/approach

A systematic literature review was conducted to identify and analyze different strategies for reducing NRW. The initial search identified 158 articles, with 41 of these deemed suitably relevant following further examination. Finally, 14 NRW reduction strategies were identified from the selected articles.

Findings

The identified NRW reduction strategies were grouped into strategies for reducing (1) apparent losses (AL), (2) real losses (RL) and (3) water losses, with the latter involving the combination of AL and RL. The strategies adopted most frequently are “prevent water leakage” and “control water pressure.” In addition, water distribution network (WDN) rehabilitation has additional benefits over other RL reduction strategies, including saving water and energy, increasing hydraulic performance and enhancing reliability. Finally, utilizing decision support systems is the only strategy capable of reducing multiple NRW categories.

Originality/value

This review provides insights into the overall NRW problem and the strategies best equipped to address it. Authorities can use these findings to develop case-specific NRW reduction action plans that save water and energy, while providing other economic benefits. In addition, NRW reduction can improve WDN reliability.

Abstract

Purpose

The purpose of this article discusses the design of underground eco-houses using a dome structure of light construction while taking into account the historical experience of the development of the local population. This article considered the traditions of folk architecture and modern sophistication in the creation of energy-efficient eco-houses in foreign countries in the context of architecture and construction of affordable residential homes for the local population.

Design/methodology/approach

The research presented in this paper was motivated by the need for developing agro-tourism facilities in hard-to-reach areas of the Silk Road in Southern Kazakhstan causes the construction of eco-houses built using local construction materials. Since ancient times in Southern Kazakhstan and during seasonal migrations in yurts of light construction, people have lived in mud-brick houses deep in the ground. Along with architectural and artistic solutions in building construction, great importance was attached to saving material resources, labour costs and achieving heat stability of residential buildings.

Findings

In the architectural and planning solution of the eco¬-house, progressive directions of construction of agrotechnical structures using renewable energy sources are adopted. Particular importance was given to the choice of the construction site on an elevated area nearby historical monuments and a favourable season for the construction of eco-houses with considering the natural and climatic characteristics of rural areas of Southern Kazakhstan.

Research limitations/implications

This paper discussed the issues of insulation, ventilation and improving the eco-house microclimate comfort using local building materials. Improving the architectural and artistic expressiveness of the eco-house in terms of the tradition of folk architecture was also explicitly discussed in this paper.

Practical implications

Tables with the justification of expediency of construction of economical eco-houses in natural and climatic conditions of Kazakhstan and Central Asia are provided. The results help to improve the energy efficiency of eco-houses in Kazakhstan by using renewable energy sources.

Social implications

Social benefits are associated with the use of local raw materials. Eco-houses built from traditional building materials can become accessible to a wide range of people and stimulate the development of small businesses. This may be associated with the construction of eco-houses to serve visiting tourists in remote picturesque oases, as well as the manufacture of dome structures, felt products and the preparation of reed panels and so on.

Originality/value

The thermotechnical characteristics of the region's ground energy are given, which can significantly save the cost of heating the eco-house. Solutions for optimal insolation, ventilation of the eco-house are provided, taking into account the natural and climatic conditions of Southern Kazakhstan.
