The Four Cs of disaster partnering: communication,cooperation, coordination and collaboration

Public, nonprofit and private organisations respond to large‐scale disasters domestically and overseas. Critics of these assistance efforts, as well as those involved, often cite poor interorganisational partnering as an obstacle to successful disaster response. Observers frequently call for ‘more’ and ‘better’ partnering. We found important qualitative distinctions existed within partnering behaviours. We identified four different types of interorganisational partnering activities often referred to interchangeably: communication, cooperation, coordination and collaboration—the Four Cs. We derived definitions of the Four Cs from the partnering literature. We then tested them in a case study of the response to the 2010 Haiti earthquake. We suggest that the Four Cs are distinct activities, that organisations are typically strong or weak in one or more for various reasons, and that the four terms represent a continuum of increased interorganisational embeddedness in partnering activities.     

Precopulatory guarding-time of the male amphipod Eogammarus oclairi: effect of population structure

This study shows that population structure affects guarding time in the amphipod Eogammarus oclairi Bousfield. In the laboratory, mean guarding time depended on the male weight-frequency distribution, operational sex ratio, and male density. It was longer when the male population encompassed a broad range of weights than when the weight distribution was narrower; however, guarding time did not differ when the population's weight distribution was narrow and composed of either small or large males. Mean guarding time varied between a few hours when the operational sex ratio (male:female) was 1:3 to>7 d when the sex ratio was 2:1. It was also affected by male density, increasing as male density increased. The results suggest that the stimulus to guard depends on the intensity of male-male competition.     

Some of the Nineteenth Century Origins of the Sustainability Concept

Interpreting and applying the concept of sustainable development is increasingly viewed as being the way to promulgate just and practicable economic, environmental and social policy. It is thus important that there be increased public and political awareness concerning the origins of economic theory, and its early relationship to sustainability concepts. While the term 'sustainable development' was popularised by the World Commission on Environment and Development report Our Common Future in 1987, it is generally recognised that notions of sustainability were promoted in `limits to growth' and 'green' discourses in the early 1970s (Meadows et al.: 1974, The Limits to Growth: A Report for the Club of Rome, Potomac Associates and Pan Books, London and Sydney). However, there is little acknowledgement of the way in which nineteenth century intellectuals, from a range of disciplines, conceptualised the importance of balancing economic, social and environmental sustainability in their quest for justice and the conservation of nature.There was a considerable exchange of ideas on `political economy' and nature across Europe, and later the Americas, from the middle of the eighteenth century. This discourse reached its intellectual peak in the nineteenth century. During that era there was a proliferation of literature that was aimed at improving the human condition and recognising humanity's dependence upon nature. In Europe and the USA the participants in the debate included Cantillon, Quesnay, Condorcet, Galiani, Von Hayek, Marx and George. Due to the breadth of this influential body of work, we focus here on the British Victorian thinkers such as Darwin, Malthus, Martineau and Mill. These thinkers influenced each other in developing their theories and ideas in science, politics, economics and philosophy, and were influenced in turn by an earlier generation of intellectuals, such as Adam Smith. For the Victorian thinkers, conserving nature while trying to improve the distribution of wealth was a not a paradox, but a moral duty, and for them Smith's `rational' pursuit of self-interest could only be followed if it did not interfere with 'the rules of justice'. We argue that the manner in which these thinkers conceptualised their theories and ideas represents the nineteenth century origins of sustainability concepts.     

Growth and average growth rates of tanner crab zoeae collected from the plankton

Growth of the two zoeal stages of Tanner crabs, Chionoecetes bairdi and C. opilio, was estimated by changes in total dry weight of individuals sampled from plankton of the southeastern Bering Sea during the springs of 1977, 1978, 1980 and 1981. Since the age of larvae within a stage cannot be determined, approximate beginning and end weights of each stage were used. Epidermal retraction, conspicuous under low magnification of a dissecting microscope, was used to identify larvae presumed to be in advanced stages of growth (biomass) for their respective larval stage. This assumption was corroborated by holding retracted larvae that subsequently molted on board ship, by comparison of dry weight measurements from extensive field sampling, and by the low proportion of larvae showing such conspicuous retraction. An exponential growth model was used to calculate the average daily growth rate based on estimates of stage duration in the field. The adequacy of this model for describing the average rate, rather than the pattern, of growth is discussed. Carbon-specific rates of respiration from discrete measurements and of growth averaged for each zoeal stage indicate average net growth efficiencies comparable to laboratory results for other species. The method used to estimate growth should be applicable to other larval decapods and offers the advantage of estimating this parameter from data gathered from natural populations.Contribution No. 652 of the School of Fisheries, University of Washington     

Chemical reactivities of ambient air samples in three Southern California communities

The potential adverse health effects of PM_2.5 (particulate matter with an aerodynamic diameter <2.5 μm) and vapor samples from three communities that neighbor railyards, Commerce (CM), Long Beach (LB), and San Bernardino (SB), were assessed by determination of chemical reactivities attributed to the induction of oxidative stress by air pollutants. The assays used were dithiothreitol (DTT)- and dihydrobenzoic acid (DHBA)-based procedures for prooxidant content and a glyceraldehyde-3-phosphate dehydrogenase (GAPDH) assay for electrophiles. Prooxidants and electrophiles have been proposed as the reactive chemical species responsible for the induction of oxidative stress by air pollution mixtures. The PM_2.5 samples from CM and LB sites showed seasonal differences in reactivities, with higher levels in the winter, whereas the SB sample differences were reversed. The reactivities in the vapor samples were all very similar, except for the summer SB samples, which contained higher levels of both prooxidants and electrophiles. The results suggest that the observed reactivities reflect general geographical differences rather than direct effects of the railyards. Distributional differences in reactivities were also observed, with PM_2.5 fractions containing most of the prooxidants (74–81%) and the vapor phase most of the electrophiles (82–96%). The high levels of the vapor-phase electrophiles and their potential for adverse biological effects point out the importance of the vapor phase in assessing the potential health effects of ambient air.

Implications:?PM_2.5 and its corresponding vapor phase, containing semivolatile organics, were collected in three communities in the Los Angeles Basin and examined with toxicologically relevant chemical assays. The PM_2.5 phase contained most of the prooxidants and the vapor phase contained most of the electrophiles, whose content was highest in summer samples from a receptor site that reflected greater photochemical processing of the air parcel during its transport. As electrophiles initiate both adverse and adaptive responses to foreign substances by biological systems, their presence in the vapor phase emphasizes the importance of this phase in the overall health effects of ambient air.     

Follow-up on a 1962 case-control study of trace elements as risk factors for stomach cancer in Iceland

In 1988 a follow-up investigation was made of a case-control study conducted in 1962 in Iceland which tested hypotheses that trace elements in pasture grass, drinking water and cow's milk were associated through diet with cancer of the stomach. Samples were collected in 1962 from 26 farms in the northern county of Skagafjardarsysla and 30 farms in the southern county of Rangarvallasysla. The main objective of the present study was to establish the cancer experience of the 297 residents of the 56 farms since 1962. In the records of the Icelandic Cancer Registry 31 cases of cancer of all types were identified. Six were cancers of the stomach and four of these were from control farms. The revised comparison of trace element analyses for case and control farms yielded no change in earlier results for pasture grass in Skagafjardarsysla (excess levels of B, Na, AI, Fe and Cu on cancer farms), but B appeared as a significant deficiency on cancer farms in Rangarvallasysla. Drinking water results were unchanged (no significant differences), but for milk the significantly high mean values of Fe and Zn reported earlier for Rangarvallasysla did not appear. The pronounced geographical variation in Icelandic stomach cancer incidence that was widely cited from 1961–65 is now believed to have been spurious.     

Evidence for multiple recruitment-cohorts of Puget Sound Dungeness crab,Cancer magister

While sampling intertidally in Puget Sound, Washington, USA, for juvenile Dungeness crab (Cancer magister) in 1984, we found evidence of two distinct cohorts of the same year-class based on sizes of first-instar juveniles (J1) and the spatial/temporal patterns of settlement. In 1988, three distinct cohorts were observed to settle in Puget Sound and its approaches. Settlement of one cohort occurred during May in the Strait of Juan de Fuca and in those areas of Puget Sound closest to the Strait. J1 individuals of this cohort were large (x=7.4 mm carapace width, CW) and comparable in both size and timing of settlement to populations along the Washington coast (e.g. Grays Harbor and Willapa Bay). Initial settlement density of the May cohort was as high as 215 crabs/m² in intertidal eelgrass beds along the Strait of Juan de Fuca and decreased to <2 crabs/m² within Puget Sound and the Strait of Georgia. A second cohort apparently originated in Hood Canal (a deep inland fjord), its size upon settlement in June was significantly smaller (J1 x= 5.3 mm CW) than the May cohort, and it was limited to Hood Canal and areas of Puget Sound close to the mouth of Hood Canal. A third cohort, which settled in late July and August, was the smallest of the three cohorts (J1 x= 4.8 mm CW), and was widely distributed around Puget Sound from Seattle in the south to the USA/Canadian border in the north. We hypothesize that most juvenile recruitment in Hood Canal and Puget Sound originates from parental stocks endemic to their respective basins (Hood Canal and Puget Sound cohorts), but that, on occasion, oceanographic conditions allow substantial influx of Pacific Ocean Dungeness crab larvae (oceanic cohort) through the Strait of Juan de Fuca into Puget Sound. Tracking of spatial/temporal settlement patterns and comparison of J1 sizes proved useful for estimating the probable sources and dispersion of Dungeness crab larvae. Differences in size and time of settlement between various larval cohorts of C. magister may prove useful as biomarkers for tracing circulation patterns within and between inland waters of Washington and the Pacific Ocean. Causes of smaller size and later settlement of the Puget Sound cohort relative to oceanic conspecifics of the same year-class are discussed.Contribution No. 856, School of Fisheries, University of Washington, Seattle     

Mercury photoreduction and photooxidation in lakes: Effects of filtration and dissolved organic carbon concentration

Mercury is a globally distributed, environmental contaminant. Quantifying the retention and loss of mercury is integral for predicting mercury-sensitive ecosystems. There is little information on how dissolved organic carbon(DOC) concentrations and particulates affect mercury photoreaction kinetics in freshwater lakes. To address this knowledge gap,samples were collected from ten lakes in Kejimkujik National Park, Nova Scotia(DOC: 2.6–15.4 mg/L). Filtered(0.2 μm) and unfiltered samples were analysed for gross photoreduction, gross photooxidation, and net reduction rates of mercury using pseudo first-order curves. Unfiltered samples had higher concentrations(p = 0.04) of photoreducible divalent mercury(Hg(II)RED)(mean of 754 ± 253 pg/L) than filtered samples(mean of 482 ± 206 pg/L);however, gross photoreduction and photooxidation rate constants were not significantly different in filtered or unfiltered samples in early summer. DOC was not significantly related to gross photoreduction rate constants in filtered(R~2= 0.43; p = 0.08) and unfiltered(R~2= 0.02; p = 0.71) samples; DOC was also not significantly related to gross photooxidation rate constants in filtered or unfiltered samples. However, DOC was significantly negatively related with Hg(Ⅱ)_(RED) in unfiltered(R2= 0.53; p = 0.04), but not in filtered samples(R~2= 0.04;p = 0.60). These trends indicate that DOC is a factor in determining dissolved mercury photoreduction rates and particles partially control available Hg(Ⅱ)_(RED) in lake water. This research also demonstrates that within these lakes gross photoreduction and photooxidation processes are close to being in balance. Changes to catchment inputs of particulate matter and DOC may alter mercury retention in these lakes and could partially explain observed increases of mercury accumulation in biota.     

Soil physical parameters and earthworm populations associated with opencast coal working and land restoration

A study of physical and biological soil parameters was undertaken on reinstated opencast coal sites of varying ages from final topsoil replacement. Earthworm population levels were determined at the same time as sampling of pH, particle size analysis and bulk density. The results indicated that the pH of a site was not limiting to earthworm activity, but that all the reinstated sites had zones of compaction which were remnants of the restoration practice and may be limiting to earthworm activity. Total earthworm populations reached levels similar to undisturbed adjacent controls within 10–20 years after topsoil replacement, although there were differences in species composition.     

Defining response capacity to enhance climate change policy

Climate change adaptation and mitigation decisions made by governments are usually taken in different policy domains. At the individual level however, adaptation and mitigation activities are undertaken together as part of the management of risk and resources. We propose that a useful starting point to develop a national climate policy is to understand what societal response might mean in practice. First we frame the set of responses at the national policy level as a trade off between investment in the development and diffusion of new technology, and investment in encouraging and enabling society to change its behaviour and or adopt the new technology. We argue that these are the pertinent trade-offs, rather than those usually posited between climate change mitigation and adaptation. The preference for a policy response that focuses more on technological innovation rather than one that focuses on changing social behaviour will be influenced by the capacity of different societies to change their greenhouse gas emissions; by perceived vulnerability to climate impacts; and by capacity to modify social behaviour and physical environment. Starting with this complete vision of response options should enable policy makers to re-evaluate the risk environment and the set of response options available to them. From here, policy makers should consider who is responsible for making climate response decisions and when actions should be taken. Institutional arrangements dictate social and political acceptability of different policies, they structure worldviews, and they determine the provision of resources for investment in technological innovation and social change. The importance of focussing on the timing of the response is emphasised to maximise the potential for adjustments through social learning and institutional change at different policy scales. We argue that the ability to respond to climate change is both enabled and constrained by social and technological conditions. The ability of society to respond to climate change and the need for technological change for both decarbonisation and for dealing with surprise in general, are central to concepts of sustainable development.
