Endowment Effects and Drinking Water Quality
Authors: Booth Pamela L. , Guilfoos Todd , Uchida Emi
Published: August 2016

We conduct a laboratory experiment to test for the existence of the endowment effect—a gap between willingness to accept and willingness to pay—for improved drinking water quality using a within-subject design. We find a statistically significant and positive gap. Willingness to accept is 62 to 125 cents higher than willingness to pay on average, indicating the presence of endowment effects. This gap is robust to information about the quality of water being consumed. We also identify some heterogeneity in the size of the gaps that is associated with differences in subjects' knowledge of drinking water quality and disparities in their incomes.
Behavioral Anomalies in Contingent Values and Actual Choices
Authors: Poe Gregory L.
Published: August 2016

A growing body of literature demonstrates that many behavioral anomalies observed in stated-preference elicitation methods such as the contingent valuation method are also observed in actual choices and vice versa. This presentation furthers the argument that such parallel behaviors should be viewed as a strength of stated-preference methods. Three well-known anomalies observed in both stated preferences and actual choices are first reviewed to lay the foundation for this argument. A number of lesser-known anomalies are then presented to demonstrate the wider prevalence of parallel anomalies in stated preferences and actual choices.

Published: August 2016

Studies of palaeo-accumulation rates at Dome A, East Antarctica, are entirely absent. Here, spatio-temporal variations in ice accumulation rates for the past ~161 ka are calculated from isochronous internal layering, traced from radio-echo sounding (RES) data collected by the Polar Research Institute of China (PRIC) during the 21st CHINARE. The layers are dated by linking them to the site of Vostok ice core along an RES profile, which was flown by the Alfred-Wegener-Institut (AWI) in the Dome Connection East Antarctica (DoCo) project. The Dansgaard-Johnsen model is used to determine the spatial and temporal pattern of ice accumulation in Dome A region. The results show that there is a slight increasing pattern of ice accumulation from south to north along the 216 km radar profile at Dome A. The lowest ice accumulation rates were calculated around the Dome A zone. In the past ~90 ka, there were relatively high accumulation rates during the time period 34–47 ka (Marine Isotope Stage 3) at Dome A.
Analytical Critiques of Whitehead's Metaphysics
Authors: MCHENRY LEEMON B. , SHIELDS GEORGE W.
Published: August 2016

Analytic philosophers have criticized A. N. Whitehead's metaphysics for being obscure, yet several such philosophers have espoused positions in metaphysics and philosophy of mind that were advanced by Whitehead in the 1920s. In this paper, we evaluate the merits and demerits of these criticisms by Bertrand Russell, W. V. Quine, Karl Popper, and others and then demonstrate the affinities and contrasts in the positions advanced by Galen Strawson, David Chalmers, Thomas Nagel, and Whitehead regarding so-called ‘analytic panexperientialism’.
“Surveillance of the Surveillers”: Regulation of the Private Security Industry in South Africa and Kenya
Authors: Diphoorn Tessa
Published: August 2016

The growth of the private security industry on the African continent has resulted in an expanding labor force engaged in surveillance-type activities. This article analyzes various levels of regulation of private security officers as a form of surveillance. Based on qualitative methodology, it compares the numerous regulatory efforts implemented by the state, industry, and companies of the private security industry in Kenya and South Africa and shows that although different, they essentially share the ultimate aim of controlling private security officers, i.e., to implement a means of “surveillance of the surveillers.”
“Mundane Sights” of Power: The History of Social Monitoring and Its Subversion in Rwanda
Authors: Purdeková Andrea
Published: August 2016

By tracing the Rwandan state’s “mundane sights”—everyday forms of presence and monitoring—the article sheds light on the historical development and striking continuities in “interactive surveillance” across a century of turbulent political change. It considers three emblematic surveillance technologies—the institution ofnyumbakumi, the identity card, andumugandaworks (and public activities more broadly)—which, despite their implication in genocide, were retained, reworked, and even bolstered after the conflict ended. The article investigates what drives the observed continuity and “layering” of social monitoring over time, highlighting the key role played by ambiguity and ambivalence in this process. The research expands the concept of political surveillance, moving away from the unidirectional notion of “forms of watching,” and questions any easy distinctions between visibility and invisibility in the exercise of power or its subversion.
Surveillance in Niger: Gendarmes and the Problem of “Seeing Things”
Authors: Göpfert Mirco
Published: August 2016

Today, high-tech surveillance seems omnipresent in Niger, particularly because of the conflicts in neighboring Mali, Libya, and Nigeria and efforts by the U.S. and France to boost local security agencies. However, Niger is not a very efficient “registering machine,” and the gendarmes have very limited knowledge of the communities in which they work. The key to overcoming this problem of knowledge—to “see things,” as the gendarmes put it—is the nurturing of good relationships with potential informants. But as the gendarmes depend on the knowledge of locals, the power relationship between the surveillers and those observed proves far more ambiguous than generally assumed.
Hedonic Vices: Fixing Inferences about Willingness to Pay in Recent House-Value Studies
Authors: Yinger John , Nguyen-Hoang Phuong
Published: August 2016

A key tool for studying the demand for neighborhood amenities and estimating the benefits from amenity improvements is a regression of house value on amenity levels, controlling for housing characteristics. Several scholars have developed methods to address the methodological challenges, such as endogeneity, faced by these “hedonic” regressions. Unfortunately, however, some recent studies neglect basic principles of hedonic estimation in Rosen [(1974). Hedonic Prices and Implicit Markets: Product Differentiation in Pure Competition. Journal of Political Economy, 82 (1), 34–55]. After providing conceptual background, this article explains these hedonic “vices” and how to avoid them. We focus on inappropriate functional forms, inappropriate control variables, and misinterpretation of hedonic regression results. Our analysis is supported using data from the Cleveland area in 2000 and a simulation model.
Are Rawlsian Considerations of Corporate Governance Illiberal? A Reply to Singer
Authors: Blanc Sandrine
Published: August 2016

Singer has recently argued that questions related to corporate governance are beyond the reach of Rawls’s political conception of justice. This is because justice applies to the basic structure of society, understood as society’s legally coercive structures, and because corporate governance cannot be considered part of this structure in political liberalism. This commentary challenges the second part of the argument. First, it suggests that the criterion used to exclude corporate governance from the basic structure—whether employees can exit economic organizations—is not conclusive for corporate governance, notably as institutionalized in corporate law. Second, even if the focus were on corporate governance, it would still be possible to argue that it legally coerces citizens, if not employees, in a relevant way. Thus, the argument is not successful in demonstrating that political liberalism goes beyond its legitimate boundaries when considering that aspects of corporate governance may be matters of justice.

Published: August 2016

Objectives

Despite documented increases in emergency department (ED) mental health (MH) presentations, there are inconsistent findings on the characteristics of patients with repeat presentations to pediatric EDs (PEDs) for MH concerns. Our study sought to explore the characteristics of MH patients with repeat PED visits and determine predictors of return visits, of earlier repeat visits, and of more frequent repeat visits.

Methods

We examined data collected prospectively in a clinical database looking at MH presentations to a crisis intervention program housed within a PED from October 2006 to December 2011. Predictive models based on demographic and clinical variables were constructed using logistic, Cox, and negative binomial regression.

Results

A total of 4,080 presentations to the PED were made by the 2,900 children and youth. Repeat visits accounted for almost half (45.8%) of all presentations. Multivariable analysis identified five variables that independently predicted greater odds of having repeat presentations, greater risk of earlier repeat presentations, and greater risk of frequent repeat presentations. The five variables were: female, living in the metropolitan community close to the PED, being in the care of child protective services, taking psychotropic medications, and presenting with an actionable need in the area of mood disturbances.

Conclusions

Repeat visits account for a large portion of all MH presentations to the PED. Furthermore, several patient characteristics are significant predictors of repeat PED use and of repeating use sooner and more frequently. Further research is needed to examine interventions targeting this patient group to ensure appropriate MH patient management.

Published: August 2016

Objectives

Various medications and devices are available for facilitation of emergent endotracheal intubations (EETIs). The objective of this study was to survey which medications and devices are being utilized for intubation by Canadian physicians.

Methods

A clinical scenario-based survey was developed to determine which medications physicians would administer to facilitate EETI, their first choice of intubation device, and backup strategy should their first choice fail. The survey was distributed to Canadian emergency medicine (EM) and intensive care unit (ICU) physicians using web-based and postal methods. Physicians were asked questions based on three scenarios (trauma; pneumonia; heart failure) and responded using a 5-point scale ranging from “always” to “never” to capture usual practice.

Results

The survey response rate was 50.2% (882/1,758). Most physicians indicated a Macintosh blade with direct laryngoscopy would “always/often” be their first choice of intubation device in the three scenarios (mean 85% [79%-89%]) followed by video laryngoscopy (mean 37% [30%-49%]). The most common backup device chosen was an extraglottic device (mean 59% [56%-60%]). The medications most physicians would “always/often” administer were fentanyl (mean 45% [42%-51%]) and etomidate (mean 38% [25%-50%]). EM physicians were more likely than ICU physicians to paralyze patients for EETI (adjusted odds ratio 3.40; 95% CI 2.90-4.00).

Conclusions

Most EM and ICU physicians utilize direct laryngoscopy with a Macintosh blade as a primary device for EETI and an extraglottic device as a backup strategy. This survey highlights variation in Canadian practice patterns for some aspects of intubation in critically ill patients.
Zika Virus: A Review of Management Considerations and Controversies at Six Months
Authors: Singer Laura , Vest Kelly G. , Beadling Charles W.
Published: August 2016

Zika virus continues to pose a significant global health threat. While the outbreak pattern may seemingly mirror those of other arboviruses, unique transmission characteristics and clinical outcomes warrant a different approach to traditional public health practices. Sexual transmission and virus-associated fetal and nonfetal neurologic disorders specifically challenge conventional methods of disease protection and prevention with regard to vector control, disease surveillance, and health risk communication. The protocols for outbreak and case limitation led by the World Health Organization (in accordance with Public Health Emergency of International Concern declaration) may be augmented by localized risk categorization and assignment for Zika and future emergent outbreaks. There is currently a great deal of “behind the scenes” discussion about modifications to the formal process described in the International Health Regulations. A scalable, adaptable, and flexible process is needed that can be customized to a specific threat. (Disaster Med Public Health Preparedness. 2017;11:279–284)
QUASIRANDOM GROUP ACTIONS
Authors: GILL NICK
Published: August 2016

Let $G$ be a finite group acting transitively on a set $\unicode[STIX]{x1D6FA}$. We study what it means for this action to be quasirandom, thereby generalizing Gowers’ study of quasirandomness in groups. We connect this notion of quasirandomness to an upper bound for the convolution of functions associated with the action of $G$ on $\unicode[STIX]{x1D6FA}$. This convolution bound allows us to give sufficient conditions such that sets $S\subseteq G$ and $\unicode[STIX]{x1D6E5}_{1},\unicode[STIX]{x1D6E5}_{2}\subseteq \unicode[STIX]{x1D6FA}$ contain elements $s\in S,\unicode[STIX]{x1D714}_{1}\in \unicode[STIX]{x1D6E5}_{1},\unicode[STIX]{x1D714}_{2}\in \unicode[STIX]{x1D6E5}_{2}$ such that $s(\unicode[STIX]{x1D714}_{1})=\unicode[STIX]{x1D714}_{2}$. Other consequences include an analogue of ‘the Gowers trick’ of Nikolov and Pyber for general group actions, a sum-product type theorem for large subsets of a finite field, as well as applications to expanders and to the study of the diameter and width of a finite simple group.
The Political and Economic Consequences of Populist Rule in Latin America
Authors: Houle Christian , Kenny Paul D.
Published: August 2016

While populist rule has become increasingly prevalent in the developing world, much of our knowledge about its implications remains anecdotal and contradictory. In this article, we conduct the most comprehensive large-N cross-national test of the consequences of populist rule to date. Using data on 19 Latin American states, we find that populism’s implications are mostly negative: (1) populist regimes tend to erode institutional and legal constraints on executive authority; (2) participation rates are not higher under populist governments or for populist campaigners; and (3) populist rule, even under left-wing populists, is not associated with more redistribution than non-populist democratic rule. We perform instrumental variable estimations and a quasi-experimental analysis to address the potential endogeneity of populism.
Antimicrobial-Resistant Pathogens Associated With Healthcare-Associated Infections: Summary of Data Reported to the National Healthcare Safety Network at the Centers for Disease Control and Prevention, 2011–2014

Published: August 2016

OBJECTIVE

To describe antimicrobial resistance patterns for healthcare-associated infections (HAIs) that occurred in 2011–2014 and were reported to the Centers for Disease Control and Prevention’s National Healthcare Safety Network.

METHODS

Data from central line–associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumonias, and surgical site infections were analyzed. These HAIs were reported from acute care hospitals, long-term acute care hospitals, and inpatient rehabilitation facilities. Pooled mean proportions of pathogens that tested resistant (or nonsusceptible) to selected antimicrobials were calculated by year and HAI type.

RESULTS

Overall, 4,515 hospitals reported that at least 1 HAI occurred in 2011–2014. There were 408,151 pathogens from 365,490 HAIs reported to the National Healthcare Safety Network, most of which were reported from acute care hospitals with greater than 200 beds. Fifteen pathogen groups accounted for 87% of reported pathogens; the most common included Escherichia coli (15%), Staphylococcus aureus (12%), Klebsiella species (8%), and coagulase-negative staphylococci (8%). In general, the proportion of isolates with common resistance phenotypes was higher among device-associated HAIs compared with surgical site infections. Although the percent resistance for most phenotypes was similar to earlier reports, an increase in the magnitude of the resistance percentages among E. coli pathogens was noted, especially related to fluoroquinolone resistance.

CONCLUSION

This report represents a national summary of antimicrobial resistance among select HAIs and phenotypes. The distribution of frequent pathogens and some resistance patterns appear to have changed from 2009–2010, highlighting the need for continual, careful monitoring of these data across the spectrum of HAI types.

On the equatorial Ekman layer
Authors: Marcotte Florence , Dormy Emmanuel , Soward Andrew
Published: August 2016

The steady incompressible viscous flow in the wide gap between spheres rotating rapidly about a common axis at slightly different rates (small Rossby number) has a long and celebrated history. The problem is relevant to the dynamics of geophysical and planetary core flows, for which, in the case of electrically conducting fluids, the possible operation of a dynamo is of considerable interest. A comprehensive asymptotic study, in the small Ekman number limit $E\ll 1$, was undertaken by Stewartson (J. Fluid Mech., vol. 26, 1966, pp. 131–144). The mainstream flow, exterior to the $E^{1/2}$ Ekman layers on the inner/outer boundaries and the shear layer on the inner sphere tangent cylinder $\mathscr{C}$, is geostrophic. Stewartson identified a complicated nested layer structure on $\mathscr{C}$, which comprises relatively thick quasigeostrophic $E^{2/7}$- (inside $\mathscr{C}$) and $E^{1/4}$- (outside $\mathscr{C}$) layers. They embed a thinner ageostrophic $E^{1/3}$ shear layer (on $\mathscr{C}$), which merges with the inner sphere Ekman layer to form the $E^{2/5}$-equatorial Ekman layer of axial length $E^{1/5}$. Under appropriate scaling, this $E^{2/5}$-layer problem may be formulated, correct to leading order, independent of $E$. Then the Ekman boundary layer and ageostrophic shear layer become features of the far-field (as identified by the large value of the scaled axial coordinate $z$) solution. We present a numerical solution of the previously unsolved equatorial Ekman layer problem using a non-local integral boundary condition at finite $z$ to account for the far-field behaviour. Adopting $z^{-1}$ as a small parameter we extend Stewartson’s similarity solution for the ageostrophic shear layer to higher orders. This far-field solution agrees well with that obtained from our numerical model.

We are very pleased to bring you Volume 45 of The Australian Journal of Indigenous Education. At this moment in time, we feel that the work of AJIE has perhaps never been more important, particularly as it relates to engaging Aboriginal and Torres Strait Islander children and communities in systems of schooling. In May this year we witnessed the evacuation of school teachers from the remote community of Aurukun, Queensland in fear of violence. A group of 15 disengaged young people had threatened the School Principal and as a consequence of the evacuation, 300 engaged children were subsequently disengaged from School for the remaining five weeks of term following the closure. There is no doubt that teacher safety is paramount, similarly, there should be no doubt that community consultation and engagement in a move like this one equally so. The questions which hang in the air relate to why such levels of disengagement exist. Why are Aboriginal and Torres Strait Islander young people disengaged from schooling in Aurukun? What makes it okay that a large number of engaged Indigenous children were forcibly made to disengage from school? Why is there such disengagement from government in engaging local people in the ways in which education business is carried out with and for Aboriginal and Torres Strait Islander children and communities? The papers in this volume of AJIE then, all speak strongly to issues of engagement – the kinds of pedagogy and curriculum that can and should be in place, the kinds of relationships that can and should be in place, and the kinds of outcomes made possible when such educational moves are made. A resounding message from all of the articles in this volume is that the on-going engagement of Aboriginal and Torres Strait Islander students, parents, and communities is key to defining and achieving what educational success might mean for each individual child, context and classroom. This is by no means a new message, but the recent events in Aurukun remind us that it is one we must keep returning to – the stakes for complacency and forgetting are too high.
Exploring a post-traumatic stress disorder paradigm in Flinders sensitive line rats to model treatment-resistant depression I: bio-behavioural validation and response to imipramine
Authors: Brand Sarel Jacobus , Harvey Brian Herbert
Published: August 2016

Objective

Co-morbid depression with post-traumatic stress disorder (PTSD) is often treatment resistant. In developing a preclinical model of treatment-resistant depression (TRD), we combined animal models of depression and PTSD to produce an animal with more severe as well as treatment-resistant depressive-like behaviours.

Methods

Male Flinders sensitive line (FSL) rats, a genetic animal model of depression, were exposed to a stress re-stress model of PTSD [time-dependent sensitisation (TDS)] and compared with stress-naive controls. Seven days after TDS stress, depressive-like and coping behaviours as well as hippocampal and cortical noradrenaline (NA) and 5-hydroxyindoleacetic acid (5HIAA) levels were analysed. Response to sub-chronic imipramine treatment (IMI; 10 mg/kg s.c.×7 days) was subsequently studied.

Results

FSL rats demonstrated bio-behavioural characteristics of depression. Exposure to TDS stress in FSL rats correlated negatively with weight gain, while demonstrating reduced swimming behaviour and increased immobility versus unstressed FSL rats. IMI significantly reversed depressive-like (immobility) behaviour and enhanced active coping behaviour (swimming and climbing) in FSL rats. The latter was significantly attenuated in FSL rats exposed to TDS versus unstressed FSL rats. IMI reversed reduced 5HIAA levels in unstressed FSL rats, whereas exposure to TDS negated this effect. Lowered NA levels in FSL rats were sustained after TDS with IMI significantly reversing this in the hippocampus.

Conclusion

Combining a gene-X-environment model of depression with a PTSD paradigm produces exaggerated depressive-like symptoms that display an attenuated response to antidepressant treatment. This work confirms combining FSL rats with TDS exposure as a putative animal model of TRD.
Dawes Review 5: Australian Aboriginal Astronomy and Navigation
Authors: Norris Ray P.
Published: August 2016

The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical knowledge includes a deep understanding of the motion of objects in the sky, which was used for practical purposes such as constructing calendars and for navigation. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, recorded unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees. Putative explanations of celestial phenomena appear throughout the oral record, suggesting traditional Aboriginal Australians sought to understand the natural world around them, in the same way as modern scientists, but within their own cultural context. There is also a growing body of evidence for sophisticated navigational skills, including the use of astronomically based songlines. Songlines are effectively oral maps of the landscape, and are an efficient way of transmitting oral navigational skills in cultures that do not have a written language. The study of Aboriginal astronomy has had an impact extending beyond mere academic curiosity, facilitating cross-cultural understanding, demonstrating the intimate links between science and culture, and helping students to engage with science.
The Ursa Major Cluster Redefined as a ‘Supergroup’

Published: August 2016

We identify gravitationally bound structures in the Ursa Major region using positions, velocities and photometry from the Sloan Digital Sky Survey (SDSS DR7) and the Third Reference Catalogue of Bright Galaxies (RC3). A friends-of-friends algorithm is extensively tested on mock galaxy lightcones and then implemented on the real data to determine galaxy groups whose members are likely to be physically and dynamically associated with one another. We find several galaxy groups within the region that are likely bound to one another and in the process of merging. We classify 6 galaxy groups as the Ursa Major ‘supergroup’, which are likely to merge and form a poor cluster with a mass of ~ 8 × 1013 M⊙. Furthermore, the Ursa Major supergroup as a whole is likely bound to the Virgo cluster, which will eventually form an even larger system in the context of hierarchical structure formation. We investigate the evolutionary state of the galaxy groups in the Ursa Major region and conclude that these groups are in an early evolutionary state and the properties of their member galaxies are similar to those in the field.

Published: August 2016

A formally modeled radiocarbon chronology for a new profile through the great Neolithic tell of Vinča-Belo Brdo, Serbia, is the third interwoven strand in refining the chronology of the tell. This now joins models for the whole sequence based on the archive of early excavations, and for the last two known horizons at the top of the settlement mound, investigated in recent decades. In the new deep sounding, Vinča culture occupation from the 52nd century cal BC is slightly later than in the main sequence, probably reflecting the horizontal extension of the tell as it began to grow. The last dated occupation falls in the late 47th–early 46th century cal BC, slightly earlier than in the main sequence, but the top of the profile is affected by the slippage that caused the new excavations. Formal estimates are given for the succession and varying durations of burnt and unburnt houses, and indicate a period in the first part of the 5th millennium without house burning. Overall, the combined results from the three interwoven strands serve to produce a radically enhanced understanding of the temporality of the tell, which builds on, rather than supplants, previous research. We knew previously that Vinča-Belo Brdo was very long-lived, but now we can time that history with much greater precision. We can assert with much greater confidence that its vertical buildup was steady and largely uninterrupted. We have begun, from the work on the top of the tell and in the new deep sounding, to grasp better the fluctuations in house durations from generation to generation, and can now contrast the relative fortunes of unburnt and burnt houses. We can say much more about the timing and tempo of the ending of the tell, and about the possible circumstances in which that took place.
Asparagine reduces the mRNA expression of muscle atrophy markers via regulating protein kinase B (Akt), AMP-activated protein kinase α, toll-like receptor 4 and nucleotide-binding oligomerisation domain protein signalling in weaning piglets after lipopolysaccharide challenge

Published: August 2016

Pro-inflammatory cytokines are critical in mechanisms of muscle atrophy. In addition, asparagine (Asn) is necessary for protein synthesis in mammalian cells. We hypothesised that Asn could attenuate lipopolysaccharide (LPS)-induced muscle atrophy in a piglet model. Piglets were allotted to four treatments (non-challenged control, LPS-challenged control, LPS+0·5 % Asn and LPS+1·0 % Asn). On day 21, the piglets were injected with LPS or saline. At 4 h post injection, piglet blood and muscle samples were collected. Asn increased protein and RNA content in muscles, and decreased mRNA expression of muscle atrophy F-box (MAFbx) and muscle RING finger 1 (MuRF1). However, Asn had no effect on the protein abundance of MAFbx and MuRF1. In addition, Asn decreased muscle AMP-activated protein kinase (AMPK) α phosphorylation, but increased muscle protein kinase B (Akt) and Forkhead Box O (FOXO) 1 phosphorylation. Moreover, Asn decreased the concentrations of TNF-α, cortisol and glucagon in plasma, and TNF-α mRNA expression in muscles. Finally, Asn decreased mRNA abundance of muscle toll-like receptor (TLR) 4 and nucleotide-binding oligomerisation domain protein (NOD) signalling-related genes, and regulated their negative regulators. The beneficial effects of Asn on muscle atrophy may be associated with the following: (1) inhibiting muscle protein degradation via activating Akt and inactivating AMPKα and FOXO1; and (2) decreasing the expression of muscle pro-inflammatory cytokines via inhibiting TLR4 and NOD signalling pathways by modulation of their negative regulators.
Do nymphs and adults of three Neotropical zoophytophagous mirids damage leaves and fruits of tomato?

Published: August 2016

The predatorsMacrolophus basicornis(Stal),Engytatus varians(Distant) andCampyloneuropsis infumatus(Carvalho) consume large numbers of tomato pests such asBemisia tabaci(Gennadius) andTuta absoluta(Meyrick). However, they are zoophytophagous and feed on plant parts as well. We evaluated the type and effect of injury caused by nymphs and adults of these mirids on tomato seedlings and fruit in the absence of prey. For each mirid species, seedlings were exposed to groups of 20 nymphs or adults for 72 h, and fruits were exposed for 48 h to groups of four nymphs or adults. Type and the number of injury on stems, petioles and leaflets of tomato seedlings and fruits were recorded after removal of insects. Nymphs and adults of these mirids caused necrotic rings on the leaflets, but no injury was observed on stem and petioles. The necrotic rings on leaflets consisted of blemishes, characterized by feeding punctures surrounded by a yellowish, bleached area. The number of necrotic rings did not exceed one per individual mirid and seedlings developed normally. Nymphs also caused feeding punctures on tomato fruit, but in even lower numbers than on leaflets. Two weeks after the start of the experiment the tomato fruit still looked fresh and feeding punctures had disappeared. Adults did not cause any injury to tomato fruit. The results indicate that nymphs and adults of these zoophytophagous mirids cause little injury to tomato seedlings and fruit, even when present in high densities and in the absence of prey, making them interesting candidates for biological control.
Reassessment of the Mesozoic metasedimentary rocks and tectonic setting of Taiwan and the adjacent continental margin of eastern Asia

Published: August 2016

It remains unclear whether a crystalline basement exists in SE China (including Taiwan), whether the formation of the Tananao metamorphic belt in Taiwan was linked to subduction of the Palaeo-Pacific Plate, and whether the source rocks of the sedimentary sequences in the metamorphic belts are late Mesozoic or Palaeozoic in age. Field investigations and zircon age data in the present study indicate that there is no pre-Palaeozoic gneiss (crystalline basement) in Taiwan (although orthogneisses were produced during deformation and metamorphism of Mesozoic granites), and investigations of the metasediments show that the sedimentary sequences in the Tailuko and Yuli belts are similar. Moreover, LA-ICP-MS dating of detrital zircons from the Pingtan–Dongshan belt in Fujian Province yields a cluster of 206Pb–238U ages at ~ 210–190 Ma, and the Tailuko and Yuli belts in Taiwan have similar clusters of detrital zircon ages at 200 Ma, 160 Ma, 120 Ma and 110 Ma, as well as a later overprinting caused by arc–continent collision. The cathodoluminescence images and trace-element characteristics of the zircons show that they were originally magmatic in origin. This finding, combined with the Hf isotope data, indicates that the sources of sediments in the Tananao belt (Tailuko and Yuli belts) were relatively close to an active continental margin, and that both the Tailuko and Yuli belts have similar sedimentary sources. From the margin of the Chinese mainland to Taiwan, the metasediments seem to represent a continuous sequence of deposits ranging in age from Jurassic to Cretaceous, but with the sediments becoming progressively younger towards the east. It can be inferred that the sediments in the Tailuko and Yuli belts were continental-shelf sequences with sources in SE China.
Estimating crop water deficit during maize potential growth period and climatic sensitivity analysis in Northeast China, 1961–2010

Published: August 2016

One of the probable adverse effects of climate change on agriculture is yield loss due to water scarcity. Assessment of meteorological drought risk with the index of crop water deficit (CWD) can help in determining appropriate adaptation strategies to counter such losses. Using daily weather data from 68 stations in Northeast China (NEC) for 1961–2010, the spatial and temporal behaviour ofCWDwas assessed and the sensitivity of climatic variables related toCWDduring the potential growth period of maize was explored. The results indicated that the potential maize growth period decreased by 26 days due to climate warming. The deficit (i.e. a negative value for water demand) decreased from east to west and decreased gradually during 1978–1984 and sharply during 2000–2010. It is noteworthy that NEC experienced severe droughts especially in the 1970s and the 2000s, and relative humidity was the most sensitive parameter affecting evapotranspiration. Regions in the middle of Heilongjiang and Jilin should take precautions concerning climate change effects onCWD, while the northern part of NEC should take precautions concerning changes in temperature and sunshine hours. Growing late-maturing and drought-tolerant maize varieties is therefore a good option for higher production in NEC, coupled with enhancing the availability of water in this limited-rainfall region, and should form a part of the strategy to cope with climate change.

Standard productivity measures indicate large fluctuations in technology during the Great Depression. This article's historical technology series (1892–1966), controlled for aggregation effects, varying input utilization, non-constant returns, and imperfect competition, does not indicate technology regress such that could trigger the downturn. In contrast, technology improvements in the recovery were so rapid that, over the whole Great Depression period, technology growth was highest among pre-WWII decades. This article also finds that output changed little and inputs fell when technology improved in the pre-WWII period. Real-business-cycle models have difficulty in explaining pre-WWII business cycles characterized by such responses.
A Note on Technology Shocks and the Great Depression

Published: August 2016

The role of technology shocks as a driver of the Great Depression is the topic of our own earlier work and the paper by Watanabe in this issue. While the two studies differ in their data and assumptions, they complement each other and strengthen the conclusion of both papers: technology shocks were not the driving force of the Great Depression.

Objective:

To develop an ovine model for teaching suspension laryngoscopy and phonosurgery.

Methods:

The head and neck from 10 pre-pubescent sheep were harvested following humane euthanasia at the end of anin vivoprotocol. No live animals were used in this study. The tissues were saline-perfused and refrigerated for 1–5 days. Suspension laryngoscopy was performed using adolescent Parsons and adult Kantor-Berci laryngoscopes suspended with a Benjamin-Parsons laryngoscope holder. Visualisation was achieved with 0° and 30° telescopes, and a three-chip camera and video system. Shapshay-Ossoff microlaryngeal instruments were used for endolaryngeal dissection.

Results:

Experienced laryngologists led a second year medical student through several procedures including injection laryngoplasty, hydrodissection and incision, endolaryngeal suturing, and partial cordectomy. Despite expected anatomical differences, the model proved highly realistic for suspension microlaryngoscopy.

Conclusion:

The sheep head and neck model provides an inexpensive, safe model for developing skills in suspension laryngoscopy and basic phonosurgery.
Truth-Justice-Reparations Interaction Effects in Transitional Justice Practice: The Case of the ‘Valech Commission’ in Chile
Authors: COLLINS CATH
Published: August 2016

Recent thinking and practice in transitional justice suggest that victims and societies hold indivisible, perhaps even simultaneous, rights to truth, justice and reparations after gross human rights violations. This article analyses the advantages and drawbacks of such holistic approaches to transitional justice, through a case study of Chile's second official truth commission, the ‘Valech Commission’. The article illustrates the politics of ongoing contestation about authoritarian era crimes in Latin America, showing how and why the commission was designed to deliver on certain truth-and-reparations obligations towards survivors of past state repression, while attempting to explicitly decouple truth revelations from judicial consequences. It also discusses the implications of associating truth-telling and reparations in a single instance, and in doing so contributes to debates about the potentially contradictory or counterproductive outcomes that may arise from the yoking together of truth, justice and reparations functions in transitional justice policy design.
Status of population dynamics of the Asian wedge clam,Donax scortum(Bivalvia: Donacidae): a first report from Asia
Authors: Singh Yambem Tenjing
Published: August 2016

For the management of mollusc resources, knowledge of various population parameters and exploitation level of the population of wedge clams are needed. Population dynamics on wedge clam,Donax scortumis still unknown in Asia. FAO-ICLARM Stock Assessment Tools (commonly known as FiSAT) was used for calculating population parameters of this species. The specimens ofD. scortumwere collected from Padukere sandy beach at monthly intervals from February 2009 to January 2010. Asymptotic length (Lα) was 70.88 mm and growth coefficient (K) was estimated at 0.64 year−1. The sizes attained byD. scortumwere 33.51, 51.17, 60.49, 65.40, 67.99 and 69.36 mm at the end of first, second, third, fourth, fifth and sixth years of age, respectively. Density of clams ranged from 2 ind. m−2(June, July and August) to 8 ind. m−2(December). Biomass (total weight) of clams ranged between 10.084 g m−2(August) to 185.100 g m−2(December). Total mortality (Z) forD. scortumwas 3.20 year−1. Natural mortality (M) and fishing mortality (F) were 0.64 year−1and 2.56 year−1respectively. Exploitation level (E) was computed as 0.80, indicating that the fishery ofD. scortumin the coastal waters of Karnataka is overexploited.
One Health: parasites and beyond
Authors: BLAKE DAMER P. , BETSON MARTHA
Published: August 2016

The field of parasitism is broad, encompassing relationships between organisms where one benefits at the expense of another. Traditionally the discipline focuses on eukaryotes, with the study of bacteria and viruses complementary but distinct. Nonetheless, parasites vary in size and complexity from single celled protozoa, to enormous plants like those in the genus Rafflesia. Lifecycles range from obligate intracellular to extensive exoparasitism. Examples of parasites include high-profile medical and zoonotic pathogens such as Plasmodium, veterinary pathogens of wild and captive animals and many of the agents which cause neglected tropical diseases, stretching to parasites which infect plants and other parasites (e.g. Kikuchi et al. 2011; Hotez et al. 2014; Blake et al. 2015; Hemingway, 2015; Meekums et al. 2015; Sandlund et al. 2015). The breadth of parasitology has been matched by the variety of ways in which parasites are studied, drawing upon biological, chemical, molecular, epidemiological and other expertise. Despite such breadth bridging between disciplines has commonly been problematic, regardless of extensive encouragement from government agencies, peer audiences and funding bodies promoting multidisciplinary research. Now, progress in understanding and collaboration can benefit from establishment of the One Health concept (Zinsstag et al. 2012; Stark et al. 2015). One Health draws upon biological, environmental, medical, veterinary and social science disciplines in order to improve human, animal and environmental health, although it remains tantalizingly difficult to engage many relevant parties. For infectious diseases traditional divides have been exacerbated as the importance of wildlife reservoirs, climate change, food production systems and socio-economic diversity have been recognized but often not addressed in a multidisciplinary manner. In response the 2015 Autumn Symposium organized by the British Society for Parasitology (BSP; https://www.bsp.uk.net/home/) was focused on One Health, running under the title ‘One Health: parasites and beyond…’. The meeting, held at the Royal Veterinary College (RVC) in Camden, London from September 14th to 15th, drew upon a blend of specialist parasitology reinforced with additional complementary expertise. Scientists, advocates, policy makers and industry representatives were invited to present at the meeting, promoting and developing One Health understanding with relevance to parasitology. The decision to widen the scope of the meeting to non-parasitological, but informative topics, is reflected in the diversity of the articles included in this special issue. A key feature of the meeting was encouragement of early career scientists, with more than 35% of the delegates registered as students and 25 posters.
A stochastic model to investigate the effects of control strategies on calves exposed toOstertagia ostertagi

Published: August 2016

Predicting the effectiveness of parasite control strategies requires accounting for the responses of individual hosts and the epidemiology of parasite supra- and infra-populations. The first objective was to develop a stochastic model that predicted the parasitological interactions within a group of first season grazing calves challenged byOstertagia ostertagi, by considering phenotypic variation amongst the calves and variation in parasite infra-population. Model behaviour was assessed using variations in parasite supra-population and calf stocking rate. The model showed the initial pasture infection level to have little impact on parasitological output traits, such as worm burdens and FEC, or overall performance of calves, whereas increasing stocking rate had a disproportionately large effect on both parasitological and performance traits. Model predictions were compared with published data taken from experiments on common control strategies, such as reducing stocking rates, the ‘dose and move’ strategy and strategic treatment with anthelmintic at specific times. Model predictions showed in most cases reasonable agreement with observations, supporting model robustness. The stochastic model developed is flexible, with the potential to predict the consequences of other nematode control strategies, such as targeted selective treatments on groups of grazing calves.

We studied the monogenean communities of 34 species of butterflyfish from the tropical Indo-West Pacific, identifying 13 dactylogyrid species (including two species that are presently undescribed). Monogenean assemblages differed significantly between host species in terms of taxonomic structure, intensity and prevalence. Parasite richness ranged from 0 (Chaetodon lunulatus) to 11 (C. auriga, C. citrinellus and C. lunula). Host specificity varied between the dactylogyrids species, being found on 2–29 of the 34 chaetodontid species examined. Sympatric butterflyfish species were typically parasitized by different combinations of dactylogyrid species, suggesting the existence of complex host–parasite interactions. We identified six clusters of butterflyfish species based on the similarities of their dactylogyrid communities. Dactylogyrid richness and diversity were not related to host size, diet specialization, depth range or phylogeny of butterflyfish species. However, there was a weak positive correlation between monogenean richness and diversity and host geographical range. Most communities of dactylogyrids were dominated by Haliotrema aurigae and H. angelopterum, indicating the importance of the genus Haliotrema in shaping monogenean communities of butterflyfishes. This study casts light on the structure of the monogenean communities of butterflyfishes, suggesting that the diversity and complexity of community structures arises from a combination of host species-specific parameters.
