Characterizing the urban human environment system in Boston, Massachusetts
Access to natural resources and restorative green space, especially in urban areas, has become critically important as an increasing number of people throughout the world move into cities. Stewardship of natural spaces and a sense of engagement with these environmental benefits are crucial, especially in urban areas where access to nature is more difficult and less equitable. This research proposes a model where individual and policy level values and decisions shape how urban nature is used, which affects the adoption of environmentally responsible behavior and natural resource conservation and in turn feeds back into environmental values and decisions. The research addresses four gaps in the existing literature; 1) the affect of risk on individual level ERB on private property, 2) how environmental attitudes affect policy level decisions about natural resource conservation, 3) how ecological availability can limit equitable distribution of urban green space, and 4) the ways in which users engage with small, community-driven urban green spaces. Policy implications and suggestions for further research are also discussed
Working Group 11F Opening Comments NASA Planning for NASA's Future Ground Systems
These are simple charts for the introductory comments to be made at the start of a panel session at the Ground System Architecture Workshop (GSAW2016). It is not meant as a formal paper, but rather contains information to prompt further discussion of the panel members and audience. The panel topic is: Embracing Change via the Use of Service-Based Frameworks and Products in an Enterprise
Using Publish-Subscribe Messaging for System Status and Automation
The NASA Goddard Mission Services Evolution Center (GMSEC) system is a message-based plug-and-play open system architecture used in many of NASA mission operations centers. This presentation will focus on the use of GMSEC standard messages to report and analyze the status of a system and enable the automation of the system's components. In GMSEC systems, each component reports its status using a keep-alive message and also publishes status and activities as log messages. In addition, the components can accept functional directive messages from the GMSEC message bus. Over the past several years, development teams have found ways to utilize these messages to create innovative display pages and increasingly sophisticated approaches to automation. This presentation will show the flexibility and value of the message-based approach to system awareness and automation
Employee representation and partnership in the non-union sector: a paradox of intention?
Non-union forms of employee representation have become increasingly prominent in UK workplaces in the last 15 years. In addition, partnership working has been encouraged by New Labour, the Chartered Institute of Personnel and Development, the Confederation of British Industry and the TUC as a route to higher commitment and higher individual and organisational performance. These trends have been further encouraged by recent European Union legislation. This article seeks to examine the implied linkages between non-union employee representative
mechanisms and partnership working and their influence on the effectiveness of employee voice as a conduit of high performance. The article is based on a case study
organisation from within the UK finance sector, and data are drawn from semistructured interviews with managers and staff and a survey of employee attitudes. The article concludes that employers’ attempts to utilise a non-union partnership framework for organisational gain are severely constrained by structural limitations on effective employee voice
Best Practices for Operations of Satellite Constellations
This paper presents the best practices used by several commercial and government operators of satellite constellations. These best practices were identified through a series of seminars and discussions held at NASA Goddard Space Flight Center (GSFC). The best practices are arrived through many years of experience and improvements made in the operations procedures and the operational systems with the primary drivers as mission safety and cost effectiveness. This paper discusses the operational aspects associated with how different organizations manage complexities of constellation operations. For the purposes of this paper, satellite constellations are groups of similar spacecraft with more than one spacecraft needed to fully accomplish the constellation's missio
A Successful Component Architecture for Interoperable and Evolvable Ground Data Systems
The National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) has adopted an open architecture approach for satellite control centers and is now realizing benefits beyond those originally envisioned. The Goddard Mission Services Evolution Center (GMSEC) architecture utilizes standardized interfaces and a middleware software bus to allow functional components to be easily integrated. This paper presents the GMSEC architectural goals and concepts, the capabilities enabled and the benefits realized by adopting this framework approach. NASA experiences with applying the GMSEC architecture on multiple missions are discussed. The paper concludes with a summary of lessons learned, future directions for GMSEC and the possible applications beyond NASA GSFC
Partnership with and without trade unions in the UK financial services: filling or fuelling the representation gap?
Partnership theory proposes that an appropriate integration of direct and indirect employee participation mutually benefits workers and company. This study explores the putative employee voice gains and the risks for union effectiveness by comparing employees' evaluation of partnership practices at two financial service companies with nonunion and union employee representation respectively
Partnership, high performance work systems and quality of working life
The paper measures the effects of workplace partnership and
selected high performance work practices on four different
dimensions of employee experience. Whilst the partnership–
high performance work systems nexus seems to have little
impact on employees’ job satisfaction or sense of attachment, it does, however, have a negative impact on both workplace stress and employee evaluations of union performance. The analysis thus questions common assumptions about the inevitability of ‘mutual gain’ and the necessity of employer/union partnership
