Sustainable rural drinking water is a widespread aim in India, and globally, from the household to district, state, and national scales. Sustainability issues in the rural drinking water sector range from increasing water demand to declining groundwater levels, premature deterioration of village schemes and services, inadequate revenues for operations and maintenance, weak capacity of water operators, frequently changing state and national policies, and destabilizing effects of climate change. This paper focuses on the special role of district-scale drinking water planning, which operates at the intersection between bottom-up water demand and top-down water programs. After surveying the challenges associated with bottom-up and top-down planning approaches, we present recent efforts to strengthen district and block drinking water planning in the state of Maharashtra. A combination of district interviews, institutional history, village surveys, GIS visualization, and planning workshops were used to advance district planning goals and methods. Results assess bottom-up processes of water demand; top-down water programs and finance; and intermediate-level planning at the district and block scales. Discussion focuses on potential improvements in district planning methods in Maharashtra.

Groundwater is the main source of drinking water supply in Jordan. Over the past 30 years, many wellfields have been drilled and expanded to cover increasing drinking water demand caused by natural population growth, development of life standards and as a result of the influx of refugees to Jordan. In particular, northern Jordan groundwater resources have been severely depleted. Therefore, water suppliers and utilities have been increasingly challenged to meet water demand and deliver water of adequate quality and quantity to households in a timely manner. Meeting these objectives requires good data management, proper maintenance of groundwater wells, and effective wellfield management plans. We developed a novel monitoring strategy that allows the collection of relevant data for wellfield managers (e.g., yield, static and dynamic water level, as well as energy consumption). The new monitoring system, implemented in 2017, has greatly enhanced data availability in comparison to the situation between 2012 and 2016. The data are used in an operational decision support tool based on simple interpretation of the field observations. The implementation of the project was done using both bottom-up and top-down approaches for the Wadi Al Arab wellfield. Our results evidence that (i) simple strategies can lead to a significant improvement of wellfield management, reducing the maintenance time of the wells though appropriate monitoring (from an average of four days/maintenance/well in 2012 to less than one day/maintenance/well in 2017); (ii) the joint combination of bottom-up and top-down approaches leads to an effective implementation of the monitoring system; (iii) the simplicity of the proposed monitoring strategy makes it suitable for further implementation in other wellfields in Jordan and countries in a similar situation of both data and water scarcity.

Sensory regulation of quadrupedal locomotion: a top-down or bottom-up control system?

Pattern Generators

Propriospinal pathways are thought to be critical for quadrupedal coordination by coupling cervical and lumbar central pattern generators (CPGs). However, the mechanisms involved in relaying information between girdles remain largely unexplored. Using an in vitro spinal cord preparation in neonatal rats, Juvin and colleagues ( Juvin et al. 2012 ) have recently shown sensory inputs from the hindlimbs have greater influence on forelimb CPGs than forelimb sensory inputs on hindlimb CPGs, in other words, a bottom-up control system. However, results from decerebrate cats suggest a top-down control system. It may be that both bottom-up and top-down control systems exist and that the dominance of one over the other is task or context dependent. As such, the role of sensory inputs in controlling quadrupedal coordination before and after injury requires further investigation.

Psychotic experiences may best be described as an alteration in the self-ascription of thoughts and actions, which is associated with a profoundly altered experience of oneself and the surrounding world. Computational models of key symptoms of psychiatric disorders are discussed with respect to the attribution of salience and self-relatedness to otherwise irrelevant stimuli and the role of top-down modelling in the generation of delusions. Top-down and bottom-up approaches in understanding mental disorders and their computational models are compared and critically reflected.

The Third Sector

This chapter discusses the role of the third sector working with the hard and soft structures of public–private partnerships to promote healthier individuals and communities. It considers how a recommitment to the 'local authority' of citizens and beneficiaries offers the possibility of revitalised and healthier individuals and reinvigorated and healthier communities, which are unachievable through the hard and soft structures of the commissioner/provider statutory approach. The chapter then identifies the pivotal dynamic of one-to-one relationships in these processes and their association with health outcomes (emotional, physical, and spiritual) alongside the opportunities and challenges in agencies engaging/re-engaging with the agency of citizens and beneficiaries. It explores the tension between the 'agency' of citizens and beneficiaries that constitutes bottom-up power and 'agencies' with top-down power. The chapter also looks at the benefits of embracing the expertise and investment of individuals and their communities in their personal and shared lives, how this can be supported and how it can be undermined.

This research examined the relationships among tourism, well-being, and novelty-seeking as a personality trait based on the top–down and bottom–up theories of well-being. A structural model that includes a direct effect of novelty-seeking on life satisfaction (top–down influence) and an indirect effect through tourism experiences (bottom–up influence) were proposed and tested using a sample of 556 American residents. Results showed that novelty-seekers were well aware of travel benefits and traveled more frequently. It was also found that the top–down influence of novelty-seeking on life satisfaction was significantly greater than the bottom–up influence. These findings highlight the crucial role of personality as a predictor of well-being as well as the importance of applying positive psychology principles to further enhance the potential contribution of tourism experiences to tourists’ well-being.

Women's Political Participation

Abstract This paper aims to trace the development of women’s political participation in Jordan and the efforts exerted in a top-down and bottom-up approach towards gender equality. Special consideration is accorded to the constitution, in its function as a social contract mirroring societal developments and the role of the monarchy and its available tools to influence decisions and nudge societal development in ways deemed necessary. At the same time the constraints imposed on Jordan due to its special circumstances are pinpointed.
