Readability of OHS documents – A comparison of surface characteristics of OHS text between some languages

Readability of documents, including occupational health and safety (OHS) documents, is a key factor in their adoption and application. The author uses two measures of English readability favoured by the US for health communication, and in defense communications respectively. Also included is the use of measures for Chinese, Japanese, Malay/Indonesian, and Spanish. One measure, McLaughlin’s (1969) SMOG formula, was also trialed on documents in five languages other than English. The tests included parallel texts from China, Europe, Malaysia and the US, and also parallel texts in English, Chinese and Spanish, and on like topics (except for Turkish where available choices were limited). On the data obtained, it is suggested that the SMOG test with modified criteria may be applicable to Finnish, Hungarian, Malay, Spanish and possibly Turkish. Readability of the OHS documents on the measures used varied quite widely, both within and between languages. To put this in context, some internationally comparable literacy results for mid high school students are presented.     

Real-time irrigation diversion data delivery can benefit adaptive capacity in communal irrigation systems

There is a need to support applied, community-relevant hydrologic research within changing climate, population, and socioeconomic conditions to better inform water policy and management. We hypothesized that providing a rural agricultural community in a semiarid valley with the necessary monitoring tool to meet local water management needs would increase adaptive capacity within the context of long-term drought. Through a community science approach, researchers installed a telemetry monitoring system at participating acequia irrigation diversions that remotely sent water data to a web interface every 15 min. Two surveys distributed before and after web interface access targeted seven adaptive capacity indicators. After the first season of improved data accessibility, the following adaptive capacity indicators significantly increased: information diversity, cognitive social capital, leadership, and proactivity. Rather than focusing on the water savings aspect of real-time monitoring, this paper summarizes a novel water resources study that assessed the social impact of real-time irrigation water delivery monitoring on adaptive capacity. This study suggests that bridging the gap between community need and hydrologic research through community science, sociologic analysis, and stakeholder engagement provides significant benefits for communities facing water management challenges, further supporting problem-driven water resources research.     

Michael Soulé (1936–2020) on spirituality,ethics, and conservation biology

Michael Soulé is best known for his scientific contributions and central role in founding the Society for Conservation Biology and its flagship journal. Less well known are his childhood experiences, his affinity for Zen Buddhism and Arne Naess’ deep ecology philosophy, and his contributions as an environmental activist to efforts to protect biodiversity and rewild ecosystems. Also less well known is the extent to which he was an interdisciplinary environmental studies scholar, struggling to understand what promotes and hinders proenvironmental behaviors. In this regard, his life and that of many other conservation scientists provide important clues, but no easy answers. By attempting to integrate the humanities, with its quest for a meaningful and fulfilling human existence, with naturalistic nature spirituality and ecocentric values, as well as the social and natural sciences, Soulé sought to solve the riddle as to why human beings seemed unable to understand, slow, and halt negative anthropogenic environmental change. He thus modeled what interdisciplinary environmental studies is at its best. Those advocating the conservation of biological diversity have much to learn from Michael Soulé, not only from his scientific findings but also from his way of seeing, the questions he asked, and his love of the living world.     

Effects of time since fire on birds: how informative are generalized fire response curves for conservation management?

Fire is both a widespread natural disturbance that affects the distribution of species and a tool that can be used to manage habitats for species. Knowledge of temporal changes in the occurrence of species after fire is essential for conservation management in fire-prone environments. Two key issues are: whether postfire responses of species are idiosyncratic or if multiple species show a limited number of similar responses; and whether such responses to time since fire can predict the occurrence of species across broad spatial scales. We examined the response of bird species to time since fire in semiarid shrubland in southeastern Australia using data from surveys at 499 sites representing a 100-year chronosequence. We used nonlinear regression to model the probability of occurrence of 30 species with time since fire in two vegetation types, and compared species' responses with generalized response shapes from the literature. The occurrence of 16 species was significantly influenced by time since fire: they displayed six main responses consistent with generalized response shapes. Of these 16 species, 15 occurred more frequently in mid- or later-successional vegetation (> 20 years since fire), and only one species occurred more often in early succession (< 5 years since fire). The models had reasonable predictive ability for eight species, some predictive ability for seven species, and were little better than random for one species. Bird species displayed a limited range of responses to time since fire; thus a small set of fire ages should allow the provision of habitat for most species. Postfire successional changes extend for decades and management of the age class distribution of vegetation will need to reflect this timescale. Response curves revealed important seral stages for species and highlighted the importance of mid- to late-successional vegetation (> 20 years). Although time since fire clearly influences the distribution of numerous bird species, predictive models of the spatial distribution of species in fire-prone landscapes need to incorporate other factors in addition to time since fire.     

Does process fairness affect job performance? It only matters if they plan to stay

Incorporating a social exchange perspective, we examined the joint impact of process fairness and turnover intentions on job performance. Results from two independent samples suggest that employee turnover intentions moderate relations between process fairness perceptions and employee job performance. Specifically, the positive effects of the two types of process fairness on performance were stronger for employees who planned to stay with the organization than for those who intended to leave.

Evaluation and assessment of the efficacy of an abatement strategy in a former lead smelter community,Boolaroo, Australia

This study examines the recent soil Lead Abatement Strategy (LAS) in Boolaroo, New South Wales, Australia, that was designed to “achieve a reduction in human exposure to lead dust contamination in surface soils”. The abatement programme addressed legacy contamination of residential areas following closure of lead smelting operations in 2003 at the Pasminco Cockle Creek Smelter (PCCS). The principal objective of the LAS was to “cap and cover” lead-contaminated soils within the urban environment surrounding the PCCS. Soil lead concentrations of 2500–5000 mg/kg were scheduled for removal and replacement, while concentrations between 1500 and 2500 mg/kg were replaced only under limited circumstances. To date, there has been no industry, government or independent assessment of the clean-up programme that involved >2000 homes in the township of Boolaroo. Thus, by measuring post-abatement soil lead concentrations in Boolaroo, this study addresses this knowledge gap and evaluates the effectiveness of the LAS for reducing the potential for lead exposure. Soil lead concentrations above the Australian residential soil health investigation level value for residential soils (300 mg/kg) were identified at all but one of the residential properties examined (n = 19). Vacuum dust samples (n = 17) from the same homes had a mean lead concentration of 495 mg/kg (median 380 mg/kg). Bio-accessibility testing revealed that lead in household vacuum dust was readily accessible (% bio-accessible) (mean = 92 %, median = 90 %), demonstrating that the risk of exposure via this pathway remains. Assessment of a limited number of properties (n = 8) where pre-abatement soil lead levels were available for comparison showed they were not statistically different to post-abatement. Although the LAS did not include treatment of non-residential properties, sampling of community areas including public sports fields, playgrounds and schools (n = 32) was undertaken to determine the contamination legacy in these areas. Elevated mean soil lead concentrations were found across public lands: sports fields = 5130 mg/kg (median = 1275 mg/kg), playgrounds and schools = 812 mg/kg (median = 920 mg/kg) and open space = 778 mg/kg (median = 620 mg/kg). Overall, the study results show that the LAS programme that was dominated by a “cap and cover” approach to address widespread lead contamination was inadequate for mitigating current and future risk of lead exposures.
