Our study provides an industrial census of the dispersion of Internet technology to commercial establishments in the United States. We distinguish between participation, that is, use of the Internet because it is necessary for all business (e.g. email and browsing) and enhancement, that is, adoption of Internet technology to enhance computing processes for competitive advantage (e.g. electronic commerce).

We find that participation and enhancement display contrasting patterns of dispersion. In a majority of industries, participation has approached saturation levels, while enhancement occurs at lower rates with dispersion reflecting long standing industrial differences in use of computing. In general, lead adopters were drawn from a variety of industries, including many of the same industries that lead adoption of other generations of information technologies; however, the appearance of water transportation and warehousing as leading industries in Internet adoption shows that the Internet influenced establishments where logistical processes played a key role. We find large differences across industries and we caution against inferring too much from the experience in manufacturing despite the widespread availability of data in that sector.

This study examines several aspects of active portfolio management by equity hedge funds between 1996 and 2013. Consistent with the idea that cross-sectional return dispersion is a proxy for the market’s available alpha, our results show that equity hedge funds achieve their strongest performance during periods of elevated dispersion. The performance advantage is robust to numerous risk adjustments. Portfolio managers may use the current month’s dispersion to plan the extent to which the following month’s investment approach will be active or passive. We also estimate the active share for equity hedge funds and find an average of 53%. We further document the average annual expense ratio for managing hedge funds’ active share to be about 7%. This figure is remarkably close to active expense ratios reported previously for equity mutual funds, which may be interpreted as evidence of uniform pricing for active portfolio management services.

Purpose – We explore two characteristics of groups in today's work environments, membership dispersion and geographic dispersion, and the effects that these conditions have on group and organizational learning.

Approach – We integrate findings on group membership dispersion and geographic dispersion and develop predictions of dispersion's effects on group learning, incorporating the literature on knowledge transfer, transactive memory, turnover, and communication.

Findings – Members in multiple work groups, while exposed to knowledge from different areas, have weaker group identities and are more adversely affected by time constraints than members who belong to only one group. Group members can be dispersed sequentially through turnover, which creates more knowledge-retention problems than those experienced by stable groups. Members of geographically dispersed groups are in positions to integrate novel knowledge. The necessary use of technology to communicate, however, reduces the ability of geographically dispersed group members to convey ideas as effectively as their collocated counterparts. Geographically distributed group members experience less common ground and more difficulty in transferring knowledge, especially tacit knowledge, than their collocated counterparts.

Originality/value – We discuss how membership and geographic dispersion pose challenges to and provide opportunities for group learning. We suggest how learning within dispersed groups can be supported as well as what the future holds for the role of these groups in the new economy. The chapter concludes that although membership and geographic dispersion pose challenges to learning at the group level, these conditions enable learning at the level of the organization.

Agriculture accounts for most of the land use in Uzbekistan, and is consequently the main determinant of environmental quality. As a result, due to the excessive use of production inputs and irrigation, land is widely degraded in Uzbekistan. This chapter explores characteristics and changes in land use, agricultural production, soil ecosystems, and water availability, and their effects on both soil degradation and limits on sustainable development in different agro-ecological zones of Uzbekistan. Secondary data from various sources was collected and processed, and descriptive statistical methods were used to analyze trends, causes, and effects of land degradation. Zones with lower land quality have higher water-use indicators. There is a positive correlation between the land grade and fertilizer application coefficients. Agriculture from the east zone showed sustainable water consumption, the highest average land-quality grade, and has the highest fertilizer-use coefficient. The downstream west zone has the highest water-use and the lowest fertilizer-use indicators. The analysis revealed a great potential for water saving in the west and southeast agricultural zones of Uzbekistan.

Water quality and quantity will become the principal limiting factor for sustainable development in many countries across the world. “Everything living is created from water” is an ancient quotation, which closely describes the importance of water. Water insecurity is a social dilemma in the recent decades because of several factors. Moreover, the widespread presence of arsenic in groundwater, salinity in both surface and groundwater, and the insidious disaster of drought make the water insecure and the population faces water risk in their daily life. Safe drinking water as well as health problems is an issue of concern in many countries on all continents, particularly in Southeast and South Asia. Therefore, this chapter provides water insecurity issues in a broader viewpoint especially focusing on salinity, arsenic, and drought disaster that together enhance vulnerability of water sector.

This chapter tests theoretically and empirically the existence of a stable relationship between energy consumption and CO2 emissions. Based on microeconomics and physics, a model has been specified and applied to annual data for twenty countries, which representing 61 percent of the world’s population in 2018, over the period 1995–2015. The data are from the International Energy Agency (2019) and econometric techniques including panel data and causality tests have been used. The results indicate that there is a causal relationship between energy consumption and CO2 emissions. In general, consumers cannot directly change emissions caused by production processes, but they can act on emissions caused by their own domestic energy consumption. Approximately three quarters of domestic energy consumption is due to heating and domestic hot water consumption. Taking into account the lower emissions and the lower economic cost of the initial investment, four potential energy systems have been selected for use in heating and domestic hot water. Their social returns have been assessed across nine of the twenty countries in the sample over a lifecycle of 25 years from 2018: France, Portugal, Ireland, Spain, Iceland, Germany, United Kingdom, Morocco and the United States. Cost-benefit analysis techniques have been used for this purpose and the results indicate that the use of thermal water, where applicable, is the most socially profitable system among the proposed systems, followed by natural gas. The least socially profitable systems are those using electricity.

The “renaturing” of cities through an increased emphasis on the use of nature-based solutions (NBS) potentially offers urban areas the opportunity to deliver multiple environmental and socioeconomic benefits. In particular, approaches linked to NBS can limit the degree of climate exposure and vulnerability impacting upon urban infrastructures. The success of NBS in addressing climate change pressures will require an improved understanding of the characteristics of environmental risk and the ability to evaluate alternate adaptive pathways. In response, this chapter explores those components which are central to effective urban infrastructure assessment and considers how they may assist in the formulation of infrastructure strategies.

We stress the need for an approach which is both scenario-focused and fully integrated within existing spatial planning frameworks. Here, we draw specific attention to the utility of strategic environmental assessment (SEA) in both embedding environmental evaluation within mainstream spatial planning and providing the basis for the comparative evaluation of alternatives. We also argue for an approach which recognizes areas of complementary interaction between “gray infrastructure” (whether existing or proposed) and approaches linked to NBS. In order to highlight examples of potential development responses, we draw on best-practice case study examples from the European Union (EU)–funded GROWGREEN project.

“It should also be noted that the objective of convergence and equal distribution, including across under-performing areas, can hinder efforts to generate growth. Contrariwise, the objective of competitiveness can exacerbate regional and social inequalities, by targeting efforts on zones of excellence where projects achieve greater returns (dynamic major cities, higher levels of general education, the most advanced projects, infrastructures with the heaviest traffic, and so on). If cohesion policy and the Lisbon Strategy come into conflict, it must be borne in mind that the former, for the moment, is founded on a rather more solid legal foundation than the latter” European Commission (2005, p. 9)Adaptation of Cohesion Policy to the Enlarged Europe and the Lisbon and Gothenburg Objectives.

The policy for spatial organization considers three levels: the first is the distribution between the rural and urban populations, the second is the distribution of the urban population between the metropolitan region and the interior, and the third is the spatial organization of the urban population in the interior.

Leadership is a crucial driver of project performance. While traditionally, the project leader was considered as the exclusive source of leadership behavior, recent research indicates that particularly dispersed projects may profit from joint leadership efforts by all project members. However, leadership functions in dispersed projects are likely to differ from those in a face-to-face context. In this chapter, we specify shared leadership functions for the domain of geographically dispersed project teams with high levels of task uncertainty. Arguing that shared leadership in dispersed teams occurs through interrelation of individual and team actions, we specify a dispersed screening function as well as self-, other-, and team-directed interrelation functions and develop propositions on how these functions are related to project performance. Furthermore, we point to motivational aspects of shared leadership and discuss the role of the vertical leader in developing and facilitating shared leadership.
