Perceived intra-organizational mobility: Reliable versus exceptional performance as means to getting ahead

‘Work hard and get ahead’ is a fundamental tenet of modern organizations, but employees have different interpretations of what it means to ‘work hard’ and perceive that there are multiple channels to ‘get ahead’. The current research explores employees' perceptions of the factors affecting their intra-organizational upward mobility. Results using a survey instrument in a large American medical college show that employees can distinguish among intra-organizational mobility channels based on reliable role performance, on exceptional role performance, and on non-performance factors such as personal characteristics (e.g. race and gender), or luck and favoritism. Perceptions of mobility channels are related to such organizationally relevant outcomes as employee satisfaction and turnover intentions. Occupational sub-groups, however, perceive different structures for upward mobility.     

Distribution of long-lived radionuclides of the 238U series in the sediments of a small river in a uranium mineralized region of Spain

A study is presented on the distribution and mobilization of the natural U isotopes (238U and 234U), 230Th, and 226Ra in the sediments of a small river crossing an uranium mineralized zone where a disused uranium mine is located. Due to the preferential directions for surface run-off waters and to the mine's situation, one sampling point along the river bed was identified as a point of accumulation of radionuclides. The average values of the activity concentrations (Bq/kg) in this sediment sample were 5,025, 5,055, 5,915 and 1,694 for 238U, 234U, 230Th and 226Ra, respectively, while the respective average values of the activity concentrations (Bq/kg) for the sediment sample considered to give the background level were 125, 124, 131 and 370. Isotopic ratios between the descendants of 238U served to clarify some paths of distribution, involving the soils nearest to the sampling points and the location of these points with respect to the disused mine. The differences in behaviour found between the uranium, thorium and radium isotopes were associated to the mobility of these radionuclides in the fluvial system studied. Correlations between the radionuclide activity concentration ratios and stable element concentrations in the sediment samples were also investigated.     

Risk perception and trust in the context of urban brownfields

Data are reported from a postal questionnaire completed by 747 residents of two urban local authority areas within which there were sites of brownfield land with significant levels of contamination. Respondents rated their perceptions of the extent to which their neighbourhood and own home were relatively vulnerable to contamination, their concern about possible effects of contamination, their satisfaction with their council in terms of consultation with residents on housing and development issues, and their trust in their council with respect to contaminated land risks. Satisfaction with, and trust in, the council was generally low in both areas, and especially so among those who perceived themselves to be more vulnerable to contamination. Nonetheless, dissatisfaction was less marked in the area where the local authority, according to background information, had pursued a more open and proactive style of risk communication and consultation with residents. The main predictors of trust, across both areas, were perceptions that the council was openly prepared to tell residents what they knew, and that the council had residents’ interests at heart. Implications are discussed for the impact of different modes of risk communication on trust.     

Ban on landfilling of wooden pallets in North Carolina: an assessment of recycling and industry capacity

Pallets literally move the world and an estimated 2 billion of them are in use in the U.S. every day. However, pallets have a short life span and thus consume vast quantities of resources. They are also responsible for 2–3% of all waste landfilled in the United States. This is despite the fact that technologies and markets exist that allow pallets to be reused, recycled, converted into other products or turned into mulch, boiler fuels or alcohols (ethanol). The State of North Carolina's legislature debated a ban on landfilling pallets for several years and has now enacted legislation to ban this practice beginning in 2009. This study provided information used to help reach that decision.North Carolina had 103 known pallet recycling operations that were surveyed in 2003–2004. Using 34 responses, the total pallet recycling capacity in North Carolina was close to 60 million units per year, while 34 million pallets were actually recycled in 2003. The average operation employed nearly 34 persons and recycled about 326,000 pallets per year. On average, 20% of the pallets received by a recycling operation were reused, 45% were refurbished, 19% were recycled, and 15% were ground. The industry generally thought that a ban on landfilling pallets was a good idea (56%) with 18% indicating it was a bad idea. Another 18% of respondents did not care and 9% had different ideas.     

Remediation process optimization: A status report

There are hundreds of contaminated sites with remediation systems that require evaluation and modification to accomplish cleanup goals. These systems are operating well past projected cleanup schedules, cost more than projected to operate, and may not be as protective of human health and the environment as planned. Remediation process optimization (RPO) is an effective method to assess the progress of a system toward achieving cleanup goals within desired time frames and to make the necessary changes in order to reach those goals. Eight main components to the RPO process are evaluated during a review and an implementation plan of recommended changes to the system is developed. Follow‐up and tracking are essential to successful RPO programs. In this article, the authors present a summary of a recent Technical and Regulatory (TechReg) Guidance Document (Interstate Technology and Regulatory Council [ITRC], 2004) and related Technology Overview Series on Advanced Topics in RPO (ITRC, 2006) in a distilled form. © 2007 Wiley Periodicals, Inc.     

Public participation and volunteer help in monitoring programs: An assessment

A number of opportunities exist for involving the public in environmental monitoring. This paper outlines some examples where this has been done, evaluates these examples, and then summarizes some of the benefits as well as the disadvantages of this approach.     

Framing an independent,integrated and evidence-based evaluation of the state of Australia's biophysical and human environments

A new approach was developed for Australia's 2011 national State of the Environment (SoE) report to integrate the assessment of biophysical and human elements of the environment. A Common Assessment and Reporting Framework (CARF) guided design and implementation, responding to jurisdictional complexity, outstanding natural diversity and ecosystem values, high levels of cultural and heritage diversity, and a paucity of national-scale data. The CARF provided a transparent response to the need for an independent, robust and evidence-based national SoE report. We conclude that this framework will be effective for subsequent national SoE assessments and other integrated national-scale assessments in data-poor regions.     

A Modeling System to Assess Land Cover Land Use Change Effects on SAV Habitat in the Mobile Bay Estuary

Estuarine ecosystems are largely influenced by watersheds directly connected to them. In the Mobile Bay, Alabama watersheds we examined the effect of land cover and land use (LCLU) changes on discharge rate, water properties, and submerged aquatic vegetation, including freshwater macrophytes and seagrasses, throughout the estuary. LCLU scenarios from 1948, 1992, 2001, and 2030 were used to influence watershed and hydrodynamic models and evaluate the impact of LCLU change on shallow aquatic ecosystems. Overall, our modeling results found that LCLU changes increased freshwater flows into Mobile Bay altering temperature, salinity, and total suspended sediments (TSS). Increased urban land uses coupled with decreased agricultural/pasture lands reduced TSS in the water column. However, increased urbanization or agricultural/pasture land coupled with decreased forest land resulted in higher TSS concentrations. Higher sediment loads were usually strongly correlated with higher TSS levels, except in areas where a large extent of wetlands retained sediment discharged during rainfall events. The modeling results indicated improved water clarity in the shallow aquatic regions of Mississippi Sound and degraded water clarity in the Wolf Bay estuary. This integrated modeling approach will provide new knowledge and tools for coastal resource managers to manage shallow aquatic habitats that provide critical ecosystem services.     

Towards a governance of sustainable consumption transitions: how institutional factors influence emerging local food systems in Belgium

System innovations and transitions in the realm of sustainable consumption policies will seldom emerge automatically from the present socio-political and socio-technical contexts. This paper explores a set of perspectives related to the governance of transitions and develops their application to the relatively unexplored governance of sustainable consumption transitions. Empirical material stems from an extensive case study which analyses a food consumption niche in the form of collectively organised local food systems (LFS) in Belgium. More specifically, we analyse and discuss the institutional contexts and socio-political configurations within which the investigated system innovation cases are embedded. The results explore the role of governmental interplay in fostering innovative consumption practices for a transition towards a more sustainable, autonomous, citizen-based, LFS.     

Post‐tsunami relocation of fisher settlements in South Asia: evidence from the Coromandel Coast,India

The tsunami that struck the coasts of India on 26 December 2004 resulted in the large‐scale destruction of fisher habitations. The post‐tsunami rehabilitation effort in Tamil Nadu was directed towards relocating fisher settlements in the interior. This paper discusses the outcomes of a study on the social effects of relocation in a sample of nine communities along the Coromandel Coast. It concludes that, although the participation of fishing communities in house design and in allocation procedures has been limited, many fisher households are satisfied with the quality of the facilities. The distance of the new settlements to the shore, however, is regarded as an impediment to engaging in the fishing profession, and many fishers are actually moving back to their old locations. This raises questions as to the direction of coastal zone policy in India, as well as to the weight accorded to safety (and other coastal development interests) vis‐à‐vis the livelihood needs of fishers.
