Sustainability Appraisal of Water Governance Regimes: The Case of Guanacaste,Costa Rica

Sustainability appraisals produce evidence for how well water governance regimes operate and where problems exist. This evidence is particularly relevant for regions that face water scarcity and conflicts. In this study, we present a criteria-based and participatory sustainability appraisal of water governance in a region with such characteristics—the dry tropics of NW Costa Rica. Data collection included 47 interviews and three stakeholder workshops. The appraisal was conducted through a collaborative and iterative process between researchers and stakeholders. Out of the 25 sustainability criteria used, seven posed a significant challenge for the governance regime. We found challenges faced by the governance regime primarily clustered around and were re-enforced by failing coordination related to the use, management, and protection of groundwater resources; and inadequate leadership to identify collective goals and to constructively deliberate alternative ways of governing water with diverse groups. The appraisal yielded some positive impact in the study area, yet we found its application provided only limited strategic information to support broader problem-solving efforts. Insights from this study suggest key starting points for sustainable water governance in the Central American dry tropics, including investing in increasingly influential collective organizations that are already active in water governance; and leveraging policy windows that can be used to build confidence and disperse more governing authority to regional and local governing actors that are in-tune with the challenges faced in the dry tropics. We conclude the article with reflections on how to produce research results that are actionable for sustainable water governance.     

How to evaluate raw material supply risks—an overview

Some strategic raw materials do have an extremely unsecure supply situation. Several working groups around the world have made criticality assessments for metallic raw materials to analyze the driving impact factors for this instability. However, the influences on raw material availability are manifold and therefore criticality assessment methods are very heterogeneous. Here we give an overview about the differences and similarities of supply risk evaluation in 15 criticality assessment methods. We take the example of Indium, which has been rated in 60% of these criticality studies, and show which data base is used for supply risk evaluation. Our results show a lack of consensus about which indicators give reliable information for raw material supply risk and how these indicators should be aggregated. We anticipate our essay to be a starting point for more justified indicator selection and weighting in criticality assessments.     

Age and innovation‐related behavior: The joint moderating effects of supervisor undermining and proactive personality

Previous research has yielded mixed results regarding the effects of age on innovation‐related behavior (IRB; i.e., generating, disseminating, and implementing new ideas). This paper hypothesizes that the relationship of age with IRB is jointly moderated by undermining behavior on the part of the supervisor and the extent to which the employee possesses a proactive personality. We collected data from 196 employees at three points in time over a one‐year period. Results supported the hypothesized 3‐way interaction of age, supervisor undermining, and proactive personality on IRB. As predicted, highly proactive older workers responded to high supervisor undermining with more IRB, whereas older workers low on proactive personality responded to high supervisor undermining with less IRB. On the other hand, when supervisor undermining was low, proactive personality did not moderate the relationship of age with IRB. Copyright © 2012 John Wiley & Sons, Ltd.     

Modeling inorganic aerosols and their response to changes in precursor concentration in Mexico City

Based on data from the 1997 Investigación sobre Materia Particulada y Deterioro Atmosférico-Aerosol and Visibility Evaluation Research (IMADA-EVER) campaign and the inorganic aerosol model ISORROPIA, the response of inorganic aerosols to changes in precursor concentrations was calculated. The aerosol behavior is dominated by the abundance of ammonia and thus, changes in ammonia concentration are expected to have a small effect on particle concentrations. Changes in sulfate and nitrate are expected to lead to proportional reductions in inorganic fine particulate matter (PM2.5). Comparing the predictions of ISORROPIA with the observations, the lowest bias and error are achieved when the aerosols are assumed to be in the efflorescence branch. Including crustal species reduces the bias and error for nitrate but does not improve overall model performance. The estimated response of inorganic PM2.5 to changes in precursor concentrations is affected by the inclusion of crustal species in some cases, although average responses are comparable with and without crustal species. Observed concentrations of particle chloride suggest that gas phase concentrations of hydrogen chloride may not be negligible, and future measurement campaigns should include observations to test this hypothesis. Our ability to model aerosol behavior in Mexico City and, thus, design control strategies, is constrained primarily by a lack of observations of gas phase precursors. Future campaigns should focus in particular on better understanding the temporal and spatial distribution of ammonia concentrations. In addition, gas phase observations of nitric acid are needed, and a measure of particle water content will allow stable versus metastable aerosol behavior to be distinguished.     

Dimensions,antecedents, and consequences of workaholism: a conceptual integration and extension

While the concept of workaholism has received a good deal of attention in the popular press, theoretical and empirical research have lagged behind. In part, the lack of a formal, agreed upon definition of the construct and its dimensions has hampered research on this topic. The purpose of this review is to offer a cohesive definition of workaholism, discuss its underlying dimensions, and identify its key antecedents and consequences. Measurement issues, directions for future research, and implications for management practice are discussed as well. Copyright © 2006 John Wiley & Sons, Ltd.     

Not drowning, waving!: Safety management and occupational culture in an Australian commercial fishing port

An ethnographic study of safety management was conducted in a commercial lobster fishing industry, in a small fishing town in Southern Australia. The objectives were to test the utility of the ethnographic method for exploring the nature of the relationship between occupational culture, workplace social organization, and safety management.Available accident data suggests this particular fishery may not have the same high incidence of occupational trauma normally attributed to commercial fishing. Changes in licensing laws and improved management of fish stocks have significantly reduced risk exposure. Participants in this study had a good understanding of their physical workplace risks, but accepted some of these with too few defences. Wear rates of personal flotation devices (PFDs) were below 1% for the study period.The paper suggests that participants do not have a strong learning culture, and links this to occupation-wide cultural assumptions, other external issues and safety management issues. Assessment of the social and cultural context of safety management can offer policy makers a ‘road-map’ to guide their interventions. The utility of ethnographic methods for this type of analysis is significant, and will be enhanced by improving the transparency of the research method.     

Off-Target Herbicide Deposition Associated with Treating Individual Trees

There are a wide variety of different herbicide treatment methods used to remove single trees. Each method (cut-stump, basal, foliar) has a unique amount of off-target disturbance that should be considered in selecting a treatment for use in management. We quantified the amount of off-target deposition that resulted from four conventional herbicide application methods: 1) basal, 2) cut-stump, 3) high-volume, hydraulic foliar, and 4) low-volume, backpack foliar. Basal and cut-stump herbicide treatments deposited up to 200 and 4000 times more herbicide (a.i. per unit area) at groundline than the low-volume and high-volume foliar treatments, respectively. On a per tree basis, basal and cut-stump treatments deposited nearly six times more total herbicide than high-volume foliar, and 68 times more than low-volume foliar. All of the herbicide deposited off-target landed within 0.6 m of the basal and cut-stump treatments, 3.7 m with the low-volume foliar, and 7.3 m with high-volume foliar methods. Off-target herbicide deposition resulted in affected areas with killed or damaged vegetation ranging in size from 0.36 m² (cut stump) to 7.08 m² (high-volume foliar). Deposition amounts and affected areas were greater with larger trees, compared to smaller ones. We observed that 48% of the total amount of herbicide applied per plot was deposited off-target with cut-stump treatment, compared to only 4% to 11% for the other treatments. We suspect this difference is due to applicator error with the cut-stump treatment, likely related to the type of spray device used to apply the treatment.
