Abstract
Estimating the escapement of small populations of steelhead Oncorhynchus mykiss (ocean-migrating rainbow trout) is challenging and requires innovative methods. Difficulties arise from rare and episodic occurrence of individuals, high turbidity levels during migration, and the need to minimize jeopardy to the fish, which have led to a lack of population estimates, especially in California. Here we show that dual-frequency identification sonar (DIDSON) can be used to produce escapement estimates for a small steelhead population in Scott Creek, Santa Cruz County, California, with virtually no impact on the fish. The DIDSON uses sound to form near-video quality images and passively monitors fish without the need to handle them or constrict passage. We deployed a DIDSON and recorded steelhead passage over three spawning seasons (2008–2010). We used a decision support tool to analyze DIDSON images and compared the resulting estimates (153, 57, and 84) with raw weir counts (50, 23, and 40), mark–recapture estimates (293 ± 9, 126 ± 12, and 109 ± 34) generated over the entire migration period, and adjusted mark–recapture estimates (201, 74, and 85), which coincided with the period of DIDSON deployment. The DIDSON and weir estimates were restricted to a smaller sampling window due to the installation of downstream migrant traps causing increased incidences of milling fish that interfered with the DIDSON results late in the migration season. The DIDSON estimates were two to three times higher than weir estimates and 23% to 55% less than the full-season mark–recapture estimates. The adjusted mark–recapture estimates followed the same trends as the full-season mark–recapture estimates and were correlated with the DIDSON estimates. We conclude that DIDSON is an effective tool to generate steelhead escapement estimates, but it is important to collect data over the entire migration season and to consider fish behavior and potential species identification issues during analysis.

Abstract
A slow-release, injectable implant method was developed for administering test chemicals to cunners Tautogolabrus adspersus. The implant is composed of a matrix of a test chemical homogenized in a mixture of Ethocel (Dow Chemical) and coconut oil. The effectiveness of a subcutaneous implant of this matrix in vivo was determined by tracing plasma concentrations of three separate chemicals (estradiol, ethynylestradiol, and atrazine) over time in treated male cunners. Release from the implant was determined based on the percentage of the implanted concentration of test chemical (plus metabolites) that was detected in fish plasma over a 1–2-week period after implantation. Circulating estrogen concentrations measured in plasma from two different cunners that received the estradiol implant were almost identical, indicating that there is a reasonably even distribution of test chemical within the Ethocel–coconut oil preparation and that individual variability may be minimal for release of test chemical from the implant. Metabolites of estradiol and atrazine were a major portion of the circulating concentration of these chemicals. Estradiol and atrazine demonstrated metabolic and clearance profiles that were very different from those of the xenoestrogen ethynylestradiol. A follow-up in vitro study was conducted to further characterize the release of estradiol from the implant matrix. Results showed a rapid release of estradiol from the matrix bolus during the first 24 h, followed by a more gradual release over subsequent days. The in vitro tests indicated that measuring in vivo plasma concentrations may not accurately reflect the release rate of a chemical from the implant matrix, in part because metabolism and clearance affect the circulating concentrations in vivo.

Abstract
Cultivation of the redtail culter Culter mongolicus has been increasing substantially over the last decade along the Yangtze River basin; such increases in production lead to increased juvenile transportation. However, redtail culter juveniles have high transport mortality rates due to a strong stress response that is exacerbated by the accumulation of toxic metabolic waste. Through a 24-h simulated transport experiment (sampling every 6 h), we assessed effects of tricaine methanesulfonate (MS-222) at 10 mg/L of water, 20 mg/L, and 40 mg/L on redtail culter survival and water quality parameters, and similarly we assessed clove oil at 2 mg/L of water, 5 mg/L, and 10 mg/L. None of the anesthetics significantly improved water quality during the initial 6–12 h of the experiment. However, MS-222 treatments at the first 12–24 h of the experiment had significantly higher dissolved oxygen (DO), ammonia, and pH than the control but failed to decrease un-ionized ammonia content. In contrast, the clove oil treatment significantly reduced the un-ionized ammonia but failed to improve DO and pH at 12–24 h. The improvements in water quality were reflected in cumulative mortality, MS-222 and clove oil anesthetic treatments having significantly lower cumulative mortality than the control at 12–24 h. The MS-222 and clove oil slowed water quality deterioration, ensured a better transport environment, and improved juvenile survival during transportation. We recommend 5 mg/L clove oil be used when transporting juvenile redtail culters because that concentration improves fish survival while keeping cost low.

Abstract
Summary: There is an immediate need for tools to both analyse and visualize in real-time single-nucleotide polymorphisms, insertions and deletions, and other structural variants from new sequence file formats. We have developed VarB software that can be used to visualize variant call format files in real time, as well as identify regions under balancing selection and informative markers to differentiate user-defined groups (e.g. populations). We demonstrate its utility using sequence data from 50 Plasmodium falciparum isolates comprising two different continents and confirm known signals from genomic regions that contain important antigenic and anti-malarial drug-resistance genes.
Availability and implementation: The C++-based software VarB and user manual are available from www.pathogenseq.org/varb.

A dual response choice experiments (DRCE) design to assess rabbit meat preference in Catalonia
Authors: Kallas Zein , Gil José Maria 
Published: September 2012

PurposeThis paper seeks to analyze consumer preferences toward fresh rabbit meat and obstacles and interest in consuming the product.Design/methodology/approachThe paper uses the dual response choice experiment (DRCE) design which allows for analyzing forced and unforced options in choice experiments using the same sample. The heteroscedastic extreme‐value (HEV) model is used due to its relaxation of the restrictive assumption made in the multinomial logit model regarding the identically distributed error term across alternatives. The empirical analysis uses consumer‐level questionnaires to elicit information regarding consumer attitudes toward rabbit meat in Catalonia (Spain).FindingsThe results demonstrate a higher preference for rabbit meat from “Catalan” origin followed by higher quality certification information. Convenience and “ready‐to‐eat” products made from rabbit meat may help bolster increased consumption. An effective communication campaign is needed to educate individuals regarding the health characteristics of rabbit compared to other types of meat. Furthermore, results demonstrate that the ordering of attributes is not significantly different from forced and non‐forced choices obtained from the DRCE design. However, significant differences on the magnitude of the preferences for some attributes' levels are found.Research limitations/implicationsFrom a methodological point‐of‐view, the study follows a similar design to the dual response choice experiments. However, the study is differentiated by asking consumers whether they are willing to buy the product. More emphasis is made on the purchasing context of the task leading consumers to focus more on their budget constraints by considering the price. The study uses the DRCE design as an alternative of the traditional single stage choice experiments. Owing to budgets constraint, the study could be improved by comparing results from both designs. At the empirical level, it would be interesting to extend the study to other geographical parts in Spain.Social implicationsThe study can help policy makers in stimulating demand for rabbit meat. Rabbit meat farmers in Catalonia were forced to abandon their farms due to the lack of demand. Consumption has decreased dramatically. As recommended in the paper, high quality labelling of the meat, improving the carcass format and its presentation and the healthiest characteristic of the meat could be a good way to promote and stimulate demand.Originality/valueFrom the empirical point‐of‐view, this study, to the authors' knowledge, is the first application of CE and CV to analyze consumers' preferences towards rabbit meat. Furthermore, it is the first paper that applies the HEV model in agro‐food economics and specifically towards rabbit meat.
Qualitative ferrographic analysis method by quantitative parameters of wear debris characteristics
Authors: Tonggang Liu , Jian Wu , Xiaohang Tang , Zhiyi Yang 
Published: September 2012

PurposeThe purpose of this paper is to propose a method of qualitative ferrographic analysis by quantitative parameters of wear debris characteristics.Design/methodology/approachThe amount of the wear debris needed for analysis on the ferrogram made by rotary ferrograph is discussed based on the theory of debris group. Quantitative parameters are constituted to express the characteristics of wear debris group, and correlation coefficients are employed to establish the relationship between wear debris and wear condition. The reliability of the method was verified by wear test experiments and ferrographic analysis.FindingsThe wear condition of machines should be determined by studying all the debris together as a group rather than by focusing on individual debris. In the proposed method, the qualitative analysis result is obtained by synthetic analysis of quantitative parameters of wear debris characteristics using a computer program, which makes the judgment of the wear system condition more objective and precise.Research limitations/implicationsIn the procedure of wear condition monitoring by the proposed method, because the weight factors and correlation coefficients introduced in this paper are determined according to the experiences deriving from practice among mining machinery, further rectifications may be needed if they are applied to other industrial field.Originality/valueThe paper illustrates a more objective and precise ferrographic analysis method for wear condition monitoring.
Facilitating the acquisition of strategic skills
Authors: Parente Diane H. , Stephan John D. , Brown Randy C. 
Published: September 2012

PurposeThe purpose of this paper is to investigate whether managers can acquire strategic skills using management education methods in lieu of experience. It demonstrates that experienced‐based pedagogical methods can be effective in developing traditional skills or “hard” skills and “soft” skills such as interpersonal communication, which then facilitate the acquisition of strategic skills.Design/methodology/approachThe paper uses data from questionnaires and achievement scores from capstone classes to determine whether exposure to an experiential technique called large‐scale simulation can lead students to acquire traditional, soft and strategic managerial skill sets.FindingsThe results show that soft and traditional skills are complementary and together lead to better acquisition of strategic skills and also imply that mastering soft skills may enhance the mastery of traditional skills.Research limitations/implicationsA limitation of the research stems from the use of students as research subjects. While this limits generalizability, it is important to remember that many such students go on to be successful managers in large and small organizations, partly due to their educational background. Replicating these findings with graduate and executive students is required.Practical implicationsA key practical implication is that organizations may be able to effectively supplement their own experienced‐based developmental efforts for their managerial personnel with course‐based learning.Originality/valueThe paper's findings support an option for many firms, although this has not received much direct empirical support. Additionally, the results support the increasing emphasis placed on soft skills, suggesting that development of strategic skills may help managers grasp the bigger‐picture implications.
Labour market experiences of skilled British migrants in Vancouver
Authors: Harvey William S. 
Published: September 2012

PurposeThe purpose of this paper is to explore the labour market experiences of highly skilled migrants from developed countries who are not linguistic or visible minorities in the host country.Design/methodology/approachThe results of the paper derive from interviews with 64 highly skilled British migrants in Vancouver. Participants were asked open‐end and closed‐ended questions and the data from the interviews were coded and analysed manually.FindingsBritish migrants were divided with their labour market outcomes. Some cited positive experiences such as better responsibility, treatment and salary, while others cited negative experiences such as having to re‐accredit, unduly proving themselves to their employers and not having their international experience recognised.Research limitations/implicationsThe results are particular to a single case study, hence they cannot be generalised or taken to represent the experiences of all British skilled migrants in Vancouver.Practical implicationsGovernments and organisations should ensure that they fulfil any promises they make to highly skilled migrants before the migration process and manage their expectations. Otherwise they face problems with brain waste and migrant retention in the short term and attracting foreign talent in the long term. They should also consider taking a more flexible approach to recognising foreign qualifications, skills and international experience.Originality/valueThe paper adds to our understanding of migrant groups from countries who share similar social and cultural characteristics to the host population. The paper shows that labour market integration challenges are not exclusive to low skilled visible minority migrants, but also to highly skilled migrants who speak the same first language and have the same skin colour as the majority of the host population.
Development of image pattern for textile based on FFT
Authors: Hongxia Jiang , Hongfu Wang , Jihong Liu , Ruru Pan 
Published: September 2012

PurposeThe purpose of this paper is to research an auto generation method of developing FFT image and image pattern for textile based on FFT theory.Design/methodology/approachIn the research, a program was developed to generate FFT images using the FFT algorithm. The process of auto generation FFT image can be divided into the following steps: initializing the size of image, painting source image, giving the color pattern, transforming FFT image by FFT, designing mask template, and image pattern combining by point diagram. These image patterns can be used to apply on the textile.FindingsThe results showed that the FFT images can be used for textile designer directly. The FFT images can also be used as elements for textile image design such as clothing. The auto generation FFT images by FFT reflect different modern sense of beauty from traditional geometric images.Research limitations/implicationsThere are many parameters that affect the art effect of FFT image generating by FFT algorithm. However, there is no discussion about the relationship between the parameters and art effect. Three dimension effects are not obvious in the simulation results by virtual clothing software.Originality/valueThe paper presents a fundamental understanding of the property of the FFT image generating by FFT algorithm and application method of the image pattern in clothing.
Simulation of bespoke garments using parametrically designed patterns
Authors: Kim Sungmin 
Published: September 2012

PurposeThe purpose of this paper is to explore the simulation of garments with various combinations of shape and size using a parametric pattern design method.Design/methodology/approachThe approach of this study is to design garment patterns using a text‐based script language and assemble them on a deformable virtual body model to evaluate the appearance and fit of the resulting garment to facilitate the garment design process.FindingsIn this study, various garment patterns are designed parametrically by an expandable script language and simulated directly on a deformable body model.Research limitations/implicationsThe size and shape of parametrically generated garment patterns are all different for each garment and therefore a full‐texture mapping technique cannot be applied.Practical implicationsThis method may reduce the time required to evaluate the appearance and fit of bespoke garments by replacing the trial‐and‐error based traditional procedures.Originality/valueThe integration of a script‐based parametric pattern design method into the garment drape simulation system is one of the most useful applications for the practical garment design process.
School‐based management developments: challenges and impacts
Authors: Bandur Agustinus 
Published: September 2012

PurposeThe purpose of this paper is to examine the current school‐based management (SBM) policy reform in Indonesia, with an emphasis on the impacts of shifting authority and responsibility to school level, as well as challenges confronted by the school council members, followed by remedial measures to minimize the problems.Design/methodology/approachThe paper employed a mixed‐method research design comprising an extensive empirical survey followed by semi‐structured and focused group interviews and examination of relevant documents. The data reported here are on the basis of an empirical survey involving 504 school council members from Ngada‐Flores, followed by 42 interviews and focus group discussion (FGD) with all relevant stakeholders.FindingsThe research findings demonstrate how devolution of power and authority to school level can create partnership in participatory school decision making in terms of setting a school mission, shared‐vision, annual programs, school budget, school textbooks, school buildings, school‐based curriculum and even students’ discipline policies. In turn, devolving power and authority to school level has created several changes in schools, including in‐school culture changes, and increased participation of school communities. These factors have led to the improvements in teaching‐learning environments and student achievements.Research limitations/implicationsThe findings of this study are specific to the context of Ngada‐Flores, Indonesia. The possibility for the general applicability of the findings is limited by the scope, the sample, and the cultural context of this study. Accordingly, even though there could be common features, the findings may not have general applicability to other systems.Practical implicationsThe paper suggests that capacity building in school level is required for the effective implementation of SBM policies and programs, including in‐service training, regular professional development sessions and workshops on effective school leadership and management, as well as school development planning.Originality/valueThis paper could be significant because of the absence of similar studies in the Indonesian context. The findings could be helpful in informing practitioners, the local and national authorities and all those interested in school education on how SBM with devolution of power and authority to school‐level decision makers assists in‐school improvements and student achievements, as well as problems and challenges confronted by school leaders in the implementation of SBM.
The gift that keeps on giving
Authors: Hodgson Tyler W. 
Published: September 2012

PurposeVarious countries have recently passed anti‐corruption and bribery laws that have international jurisdictional reach. The overlapping jurisdiction of these “long arm” statutes presents the real possibility that an offender can be twice prosecuted for the same conduct, as recently demonstrated in the case of US v. Jeong. The purpose of this paper is to highlight the difference of approach between various nations in their understanding and application of the doctrine of international double jeopardy.Design/methodology/approachThis paper explores the profound divergence in the application of the doctrine of double jeopardy in an international context, primarily by comparing and contrasting two representative jurisdictions on the subject, Canada and the USA.FindingsThe dividing line between the approach to international double jeopardy by common law nations is the doctrine of dual sovereignty. Jurisdictions which have not adopted the dual sovereignty doctrine (such as Canada) are more likely to view a prior verdict from a foreign court as a bar any further prosecution for the same offence; by contrast, countries that have adopted the dual sovereignty doctrine (such as the UA) are less likely to view a previous foreign conviction or acquittal as a bar to further prosecution.Practical implicationsIn negotiating a global settlement for acts of corruption or bribery, no finality can be achieved unless and until a resolution is reached with dual sovereignty jurisdictions.Originality/valueThis paper is of value to any individual or multi‐national concern that operates in more than one jurisdiction, as it outlines the potential dangers associated with reaching a premature global settlement for acts of bribery and corruption.
