In support of the ICRF experiments planned on the Wendelstein 7-X (W7-X) stellarator, i.e. fast ion generation, wall conditioning, target plasma production and heating, a first experimental study on plasma production has been made in the Uragan-2M (U-2M) stellarator using W7-X-like two-strap antenna. In all the experiments, antenna monopole phasing was used. The W7-X-like antenna operation with launched radiofrequency power of ~100 kW have been performed in helium (p = (4–14) × 10−2 Pa) with the vacuum vessel walls pre-loaded with hydrogen. Production of plasma with a density higher than 1012 cm−3 was observed near the first harmonic of the hydrogen cyclotron frequency. Operation at first hydrogen harmonic is feasible in W7-X future ICRF experiments.
The purpose of this chronoepidemiologic study was to investigate the time-relationships between the yearly variations in occurrence of violent suicide in Belgium and the yearly variations in various biochemical, metabolic and immune variables in the Belgian population. The weekly mean number of deaths due to violent suicide for all of Belgium for the period 1979–1987 was computed. Twenty-six normal volunteers had monthly blood samplings during one calendar year for assays of plasma L-tryptophan (L-TRP), competing amino acids (CAA), and melatonin levels, maximal [3H]paroxetine binding to platelets, serum total cholesterol, calcium, magnesium, and soluble interleukin-2 receptor concentrations, and number of CD4+ T, CD8+ T and CD20+ B lymphocytes. The annual rhythm in violent suicide rate is highly significantly synchronized with the annual rhythms in L-TRP, [3H]paroxetine binding, cholesterol, calcium, magnesium, CD20+ B cells, and CD4+/CD8+ ratio; the mean peak (violent suicide, [3H]paroxetine binding) or nadir (all other variables) occurs around 3 May. There were significant inverse time-relationships between the time series of violent suicide rate and L-TRP, L-TRP/CAA ratio, total cholesterol, calcium and magnesium, CD4+/CD8+ T cell ratio and number of CD20+ B cells. Maximal [3H]paroxetine binding to platelets was significantly and positively related to the time series of violent suicide. An important part (56.4%) of the variance in mean weekly number of violent suicide rate was explained by the time series of L-TRP, cholesterol and melatonin.
Asian tropical forests are among the most affected by overhunting of wildlife species. Bushmeat is not just a source of food, but is also often seen as an income source due to the increasing regional demand for wildlife products. In this study, we assess for the first time the medium- and large-size vertebrate species present in Lampi Marine National Park (Myanmar) using camera traps and opportunistic sightings, and we use data from law enforcement patrolling to identify areas where poaching activities occur. Nineteen different terrestrial vertebrate species were observed in the Park, five of which are listed as globally threatened, while illegal activities were recorded at 107 locations. We estimated wildlife and human distributions using the maximum-entropy (i.e., MaxEnt) algorithm. Human activities were widely distributed in the Park, and areas selected by people were those at lower elevations and mainly in evergreen or semi-evergreen forests where most of the species occur. These models could improve knowledge of species presence and of the potential risk to wildlife associated with human activities. The modelling of wildlife and human presence proved to be useful for identifying areas that would receive special attention during patrolling, management and conservation actions.
This paper focuses on systems producing short rotation coppice willows (SRCW) in chickens’ free-range areas. We aim to map chicken farmers’ motivation to implement SRCW, and to assess the economic viability of these systems. Semi-structured interviews were conducted with 18 free-range chicken farmers. Farmers agreed that chickens would prefer SRCW over grassland, which could benefit chicken welfare. They expected establishing an SRCW system would be labor intensive, and doubted if it would be a profitable investment. Some concerns of farmers might be taken away by exchanging information with farmers with SRCW experience. A partial budget analysis was performed to calculate the net present value (NPV) of six different scenarios, differing in the type of chickens, in whether the produced biomass was sold or valorized on-farm and in harvest pattern, all over a 23-yr period. The NPV was positive but low for all scenarios. A sensitivity analysis showed that changes in biomass yield, wood chip price, a price premium for poultry products and current fuel price were most likely to influence the NPV. A risk analysis revealed that NPVs were positive in the majority of the modeled cases. Scenarios in which biomass was used for on-farm heat production showed the highest risk of a negative NPV. A price premium for poultry products may be most effective at increasing profitability, but may only be feasible for farms selling directly to consumers. Establishing a solid market for biomass energy, including guaranteed demand and availability of appropriate machinery for cultivation, may mitigate farmers’ concerns.
There is a commitment by the European pig sector to ban surgical castration of male piglets in the European Union in 2018. One alternative to castration is to raise entire male pigs, with an increased risk of boar taint. A field study was performed to: (1) evaluate inter- and intra-farm variation in boar taint prevalence, (2) investigate factors measured at slaughter influencing boar taint and (3) evaluate the relationship between sensorial scoring by a trained panel and the concentration of boar taint components. From 34 farms, neck fat samples were collected from all entire male pigs in at least two slaughter batches per farm (78 batches; 9167 animals). In addition to olfactory boar taint analysis, data were also collected on fresh skin lesions (score 0 to 3) at the slaughter line, slaughter weight, lean meat percentage, duration of transport, time spent in lairage, total delivery duration, day length, shortening of days and outdoor mean temperature. Using the hot iron method, neck fat samples were scored (eight-point scale) for boar taint. Average boar taint prevalence (score ≥3) was 5.6±2.5% and the mean difference between the maximum and minimum prevalence per farm was 4.3±3.2%. Androstenone (AND), skatole (SKA) and indole concentrations were measured for a subset (n=254) of the samples. According to binomial univariate mixed models, entire male pigs with a higher skin lesion score had higher odds of having boar taint (P=0.031), as did fatter entire male pigs (P<0.001). In the binomial multivariate mixed model lean meat percentage (P<0.001) and outdoor mean temperature (P=0.005) remained as only significant factors. Based on our results, we can conclude that these statistically significant at least partially influence the prevalence of boar taint. According to the binomial univariate mixed models SKA concentration in liquid fat seems a better predictor for boar taint than AND. There were no significant synergetic effects between boar taint compounds.
Understanding motivating factors for taking soil conservation measures is seen as key to improving on-farm implementation. However, to date only few on-farm conservation measures have been investigated. The objective of this paper is to investigate the influence of farmers’ subjective beliefs on their intention to apply and actual implementation of cover cropping, with the region of Brandenburg (Germany) as a case. An additional objective was to investigate how these insights can contribute to increase farm level implementation of soil conservation measures. Theory of planned behavior provides an approach to understand human behavior by analyzing farmers’ subjective beliefs. Our results, based on a survey of 96 farmers, show that attitudes (ATTs) and perceived difficulty significantly explain variations in intention to apply cover cropping, with ATTs being generally very positive. We discuss that, in this case, the most effective way to increase on-farm implementation is to decrease the farmers’ perception of difficulty. This can be achieved by providing information to farmers on how to overcome barriers to implementation of conservation measures. In-depth insights into belief structures reveal what kind of information is most useful in the case of cover cropping.
Proportional electoral systems tend to be more beneficial for women's descriptive representation than majority systems. However, within proportional systems the gender equality of election outcomes differs, highlighting the importance of studying the actual use of electoral provisions in proportional representation (PR) systems. Therefore, we investigate the determinants of voting for female candidates in Belgium's local elections. This case is particularly interesting given the equal number of men and women on the candidate lists due to quota regulations, the possibility to cast multiple preference votes (lowering competition), and the high visibility of these local elections and its candidates. At the individual level, we find that women are more likely than men to vote for several women, yet same-sex voting is more common among men. Politically sophisticated respondents vote more often for candidates of both sexes. Against our expectations, a left-wing orientation does not increase the likelihood of voting for women. At the electoral district level, a larger supply of women at the top list position increases the chance to vote for this top woman, but there is no spillover effect to women lower on the list. District magnitude affects the number of preference votes but, against expectations, not the likelihood of voting for women.
The stirrup-spout bottle is one of the most representative forms in the Chimú (A.D. 900-1470) ceramic repertoire. I discuss the ceramic assemblage of this coastal culture and describes more precisely the various manufacturing processes of the stirrup-spout bottle. Although molds used to produce these complex vessels are known today, only little information has been published on the various stages involved in their manufacture. My purpose is to contribute to this research using medical imaging computed tomography (CT) scans of intact stirrup-spout vessels. Based on my findings, I propose that changes in the construction of these vessels correlated with a transition in ceramic production to a semi-industrial level during the time of the Chimú Empire.
Societal pressure to ban surgical castration of male piglets is rising due to animal welfare concerns, thus other methods to prevent boar taint need to be explored. Genetic selection against boar taint appears to be a long-term sustainable alternative. However, as boar taint is linked to reproductive hormones, it is important to consider possible negative side effects such as delayed sexual maturity or changes in behaviour. We reported earlier that the melanocortin-4 receptor (MC4R) marker can be used to reduce boar taint levels in fat of boars. The objective of this study was to evaluate whether MC4R marker-assisted selection for lower boar taint prevalence affects plasma levels of boar taint compounds and testosterone; sexual maturity; behaviour; skin lesions; and lameness in boars and gilts. Using an intervention study with a 2×2 design, 264 boars and gilts differing on position 893 of the MC4R gene (AA v. GG) were compared. The MC4R polymorphism did not affect the plasma concentration of either androstenone or testosterone at different time points, whereas the concentration of skatole was significantly lower (P=0.003) and the concentration of indole tended to be lower (P=0.074) in GG compared with AA boars. A higher percentage of gilts of the GG genotype were in puberty at slaughter age compared with AA gilts (P<0.001). The age of the boars at sexual maturity (as indicated by the first positive preputial smear test) did not differ between AA and GG boars. In contrast, weight of GG boars at sexual maturity tended to be lower (P=0.065). During the period from 6 weeks of age to slaughter, boars and gilts of the GG genotype showed more playing behaviour (P=0.015) and less passive and feeding behaviour (P=0.003). They showed more skin lesions on their back and caudal area (P=0.022), and tended to show more skin lesions on their head and anterior area (P=0.093) compared with AA animals. In conclusion, the polymorphism in the MC4R gene can be used as a marker without negative effects on reproduction characteristics in boars and gilts. Genetic selection towards a lower prevalence of boar taint will lead to more active pigs with more skin lesions. Management strategies may therefore be necessary to reduce skin lesions in the selected animals.
The organization of primaries in which all party members can participate is increasingly used by political parties to select their leader. We focus here on one of the consequences of these procedures – participation rates. Based on general participation theories (mobilization theory, instrumental motivation theory and learning theory) in combination with insights into the introduction and functioning of leadership primaries, we expect that the first time a party organizes leadership primaries, participation rates will be high, but that they will decline gradually afterwards. We have focused on direct member votes for the selection of party leaders in Belgium, Israel and Canada. Our results show that participation rates are not influenced by how many times such a contest is held in a party (only first-time participation tends to be higher), but mainly by how competitive the contest is.
Worldwide, politicians devote increasing attention to the sociodemographic representativeness of political institutions. The underrepresentation of specific groups (and of women in particular) in political institutions is a democratic problem (Phillips 1995). To counter the lack of representativeness of political institutions, measures have been adopted to increase the influx of female politicians in parliaments and governments. Among others, quota regulations have been implemented in several countries in recent years (Dahlerup 2007; Krook 2007).
Abstract: This paper reviews the WTO Appellate Body Reports on United States–Zeroing (EC) (Article 21.5 DSU – EC) (WT/DS294/AB/RW, 14 May 2009) and United States–Zeroing (Japan) (Article 21.5 DSU – Japan) (WT/DS322/AB/RW, 18 August 2009). The Appellate Body found that the United States had not brought its anti-dumping measures into compliance with the WTO Anti-Dumping Agreement as it continued to use zeroing in annual reviews of anti-dumping orders. We argue that this conclusion – based on a complicated discussion of what constitutes a ‘measure taken to comply’ – could have been reached through a much simpler and direct argument. Continued noncompliance by the United States generates costs to traders targeting the United States and the trading system more generally. We argue that from a broader WTO compliance perspective consideration should be given to stronger multilateral surveillance of anti-dumping practice by all WTO members and to more analysis and effective communication by economists regarding the costs of zeroing and anti-dumping practices more generally.
This paper reviews the WTO Appellate Body (AB) Reports on United States–Zeroing (EC) (Article 21.5 DSU – EC) (WT/DS294/AB/RW, 14 May 2009) and United States–Zeroing (Japan) (Article 21.5 DSU – Japan) (WT/DS322/AB/RW, 18 August 2009). These disputes concerned the manner in which the United States implemented – or failed to implement – the WTO rulings relating to the prohibition of zeroing in anti-dumping investigations and reviews. The main legal issue dealt with in these compliance cases was what prospective implementation means in the context of a retrospective system of administering anti-dumping measures.

Abstract: This paper reviews the WTO Appellate Body Report on China – Measures Affecting Imports of Automobile Parts (WT/DS342/AB/R, 15 December 2008). This dispute concerns a set of regulatory measures imposing a 25% ‘charge’ on imported automobile parts used in the manufacture of motor vehicles in China. The main legal question in this case consisted of the nature of this charge as either a border charge subject to China's tariff concessions or an internal charge, subject to the basic nondiscrimination requirement of GATT Article III. In our report, we examine the reasoning of the Appellate Body relating to the difference between these two types of charges. We discuss the role and relevance of this distinction in the GATT/WTO legal system in general, and for the purposes of resolving this dispute in particular. We also address the important systemic question relating to the review of a Member's domestic laws for purposes of determining their GATT/WTO consistency. This was an important issue in this case, as China claimed that the Panel misunderstood the meaning of the relevant Decree and requested the Appellate Body to review the Panel's erroneous reading of this Decree. We discuss the Appellate Body's reasoning relating to the review of domestic laws by Panels and the Appellate Body and express concern over the distinction drawn by the Appellate Body between legal and factual elements of relevance in the interpretation of such laws.

The ‘economic bone’ in this case is less straightforward to split than the legal one. In legal terms, the Appellate Body's decision is a time-consistent one, but, in economic terms, it is not clear if it is also a welfare-optimal one. The main reason is that many questions relevant to the case were left unaddressed by the Appellate Body. Due to the lack of factual evidence to substantiate its allegations, the Panel's ruling remains rather speculative on certain accounts. For this purpose, we engage in our own examination of the facts, using mainly a unique dataset of Chinese firm-level data. We analyze issues of ownership in China's car industry, the growth of the import-competing Chinese industry over time, the elasticity of the demand for cars, and duty pass-through, etc. The purpose is to verify more closely who ‘benefits’ and who ‘loses’ from the Chinese import duty so as to understand the economic incentives involved. In this respect, we attempt to determine whether the economics support the conclusion that China pursued a beggar-thy-neighbor policy in the car-part industry.
The Agreement on Safeguards (the Safeguards Agreement or SA) establishes rules for the application of safeguard measures, a term understood to mean those measures provided for in Article XIX of the General Agreement on Tariffs and Trade (GATT), entitled “Emergency Action on Imports of Particular Products.” Although the World Trade Organization (WTO) SA was an agreement that did not exist in the form of a plurilateral code prior to the conclusion of the Uruguay Round, it is thus nevertheless clearly rooted in the GATT system and in Article XIX of the GATT in particular. More than with any other of the WTO's Agreements, it is the relationship between the new WTO Agreement on Safeguards and the original “safeguard” provision in the GATT that proved to be problematic.
In this chapter, first, safeguard measures are discussed in the larger context of the WTO system in general and WTO trade remedies in particular. Second, the conditions for the imposition of safeguard measures will be examined. Third, the chapter addresses the application of safeguard measures in place and time, and distinguishes between the various types of measures that may be imposed as a safeguard. Some conclusions are formulated at the end.
Safeguards in the WTO Context
Safeguards as a Trade Remedy
A safeguard measure is a unilateral way of providing additional protection to the domestic industry. In that respect, safeguards are akin to other forms of contingent trade protection, such as antidumping (AD) and countervailing measures (CVMs).
During the last week of May 1986, a 1-week prospective study on antibiotic utilization in surgical patients was held in 104 (42%) of the 247 Belgian acute care hospitals. All surgical patients with a post-operative stay of at least 3 days were studied, involving 3112 patients. Each patient was observed for 7 days, starting from the day before surgery. Antibiotics were administered to 71·9% of all patients; 21·9% received therapeutic antibiotics and 52·9% prophylactic antibiotics; 2·9% received both. Of the 1285 patients undergoing a surgical procedure with no indication for antimicrobial prophylaxis, 50·7% nevertheless received prophylaxis; 92·8% of patients with a generally recognized indication for prophylaxis received antibiotic prophylaxis. Less than one fifth (17·1 %) of all prophylactic courses were stopped on the day of the intervention whilst 26·3% were continued up to the fifth post-operative day or beyond. The most frequently prescribed drugs for this indication included first and second generation cephalosporins and nitroimidazoles. The number of different generic drugs utilized per hospital ranged from 1 to 18 (mean: 7·7).
This paper reviews the WTO Appellate Body Report on United States – Anti-Dumping Measures on Oil Country Tubular Goods (OCTG) from Mexico (WT/DS282/AB/R 2 November 2005). This dispute concerns the disciplines imposed by the Anti-Dumping Agreement on WTO Members seeking to extend their anti-dumping measures beyond the original five-year period through a so-called sunset review. Our analysis focuses on the Appellate Body's finding in this case that no causation analysis is required in sunset reviews, and addresses the AB's approach towards the legal instrument that provides for the US policy in terms of sunset reviews, the Sunset Policy Bulletin. We conclude that the Anti-Dumping Agreement, as interpreted by the Appellate Body in this and other similar cases, imposes only minimal disciplines of a general nature on Members wishing to extend the anti-dumping measure beyond its original five-year period. We argue that the ‘textual’ argument relied on to support this deferential approach is weak and has resulted in undermining the practical effect of, what was considered to be, one of the major achievements of the Uruguay Round Anti-Dumping Agreement: limiting the life span of an anti-dumping measure to five years. From an economic perspective, Panels and the Appellate Body are simply debating the wrong type of questions. The prospective nature required by a sunset review analysis raises questions such as why exporters engaged in dumping in the first place, and what the conditions of the industry were so that the dumped imports caused injury. At the moment, sunset reviews seem adrift as panels and the Appellate Body fail to give guidance to Members on how to do a more economically sound and informed review.
