Influence of Lineage, Broodstock Conditioning, and Hormone Injection on Gila Trout Reproductive Success and Egg Fatty Acid Composition
Authors: Hill Heidi , Twibell Ronald , Conway Jeff , Gannam Ann , Seals John 
Published: June 2013

Abstract
Successful reproduction of captive-reared fishes depends on hatchery practices and proper broodstock nutrition. Nutrient requirements and environmental conditions stimulating reproductive development are unknown for many threatened and endangered species and may differ between lineages within species. Accordingly, prior to spawning, Main Diamond Gila Trout Oncorhynchus gilae broodstock were exposed to different thermal cycles and hormonal injection to improve reproductive success. Additionally, egg fatty acid composition and hatching success of Main and South Diamond Gila Trout were evaluated to determine the extent of phenotypic differences between lineages. Thermal conditioning of broodstock accompanied with injections of exogenous luteinizing hormone releasing hormone analog (LHRHa) prior to spawning improved progeny survival over historic hatchery means as well as means for broodstock reared in raceways at constant temperatures without LHRHa. Egg n-6 fatty acid content appears to be associated with this improvement. Eggs from Main and South Diamond broodstock fed the same feeds had similar hatch rates but could be differentiated on the basis of fatty acid profile. Future trials should further evaluate the influence of dietary fatty acids on egg deposition and hatch rate, while acknowledging that changes in reproductive performance may differ across lineages. Broodstocks should continue to be conditioned with thermal cycling and use of LHRHa to induce ovulation, as these techniques resulted in significantly better hatch rates in the current study than use of only photoperiod manipulation to stimulate reproductive development.
Potential of Asian Carp from the Illinois River as a Source of Raw Materials for Fish Meal Production

Published: June 2013

AbstractIncentivizing overfishing through the creation of high‐value markets for Silver Carp Hypophthalmichthys molitrix and Bighead Carp H. nobilis has been proposed as a management strategy for controlling Asian carp in the Illinois River. Asian carp may be rendered into a protein‐dense fish meal, and one of the most attractive, high‐value end uses for such a product is aquafeed manufacturing. However, the nutritional content and shelf stability of Asian carp as a raw material must be determined to assess its suitability for rendering and subsequent use as a protein source in aquafeeds, which was the focus of this study. To determine seasonal, geographical, and species variation in body composition, fatty acids, and oxidative stability, Asian carp were collected from five reaches of the Illinois River during the fall, spring, and summer (up to 12 individuals of each species per reach per season) and analyzed. Slight geographical, seasonal, and species variation exists in the body composition and fatty acid profiles of adult Asian carp from the Illinois River. There was an apparent trend of increasing lipid content from lower to upper reaches and from fall to summer. Bighead Carp tended to be leaner (higher protein, moisture, and ash content) than Silver Carp (higher lipid content). Although Asian carp generally appear to be a good source of long‐chain polyunsaturated fatty acids regardless of capture location or season, the concentration of these nutrients was highest in the fall. Oxidative stability analysis indicated Asian carp meal will need stabilizers to increase shelf life. Collectively, our results suggest Asian carp‐based fish meals would be nutritionally suitable for use in aquafeeds, if precautions are taken to stabilize the product during storage. Creating demand for carp meal in the aquafeed manufacturing sector may prove a valuable strategy for aiding in the control of Asian carp populations in the Illinois River.
Exact algorithms for haplotype assembly from whole-genome sequence data

Abstract
Motivation: Haplotypes play a crucial role in genetic analysis and have many applications such as gene disease diagnoses, association studies, ancestry inference and so forth. The development of DNA sequencing technologies makes it possible to obtain haplotypes from a set of aligned reads originated from both copies of a chromosome of a single individual. This approach is often known as haplotype assembly. Exact algorithms that can give optimal solutions to the haplotype assembly problem are highly demanded. Unfortunately, previous algorithms for this problem either fail to output optimal solutions or take too long time even executed on a PC cluster.
Results: We develop an approach to finding optimal solutions for the haplotype assembly problem under the minimum-error-correction (MEC) model. Most of the previous approaches assume that the columns in the input matrix correspond to (putative) heterozygous sites. This all-heterozygous assumption is correct for most columns, but it may be incorrect for a small number of columns. In this article, we consider the MEC model with or without the all-heterozygous assumption. In our approach, we first use new methods to decompose the input read matrix into small independent blocks and then model the problem for each block as an integer linear programming problem, which is then solved by an integer linear programming solver. We have tested our program on a single PC [a Linux (x64) desktop PC with i7-3960X CPU], using the filtered HuRef and the NA 12878 datasets (after applying some variant calling methods). With the all-heterozygous assumption, our approach can optimally solve the whole HuRef data set within a total time of 31 h (26 h for the most difficult block of the 15th chromosome and only 5 h for the other blocks). To our knowledge, this is the first time that MEC optimal solutions are completely obtained for the filtered HuRef dataset. Moreover, in the general case (without the all-heterozygous assumption), for the HuRef dataset our approach can optimally solve all the chromosomes except the most difficult block in chromosome 15 within a total time of 12 days. For both of the HuRef and NA12878 datasets, the optimal costs in the general case are sometimes much smaller than those in the all-heterozygous case. This implies that some columns in the input matrix (after applying certain variant calling methods) still correspond to false-heterozygous sites.

Abstract
Litz, M. N. C., Emmett, R. L., Bentley, P. J., Claiborne, A. M., and Barceló, C. Biotic and abiotic factors influencing forage fish and pelagic nekton community in the Columbia River plume (USA) throughout the upwelling season 1999–2009. – ICES Journal of Marine Science, 71: . Large river plumes modify coastal environments and can impact production across multiple trophic levels. From 1999 to 2009, the assemblages of forage fish, predator fish, and other pelagic nekton were monitored in coastal waters associated with the Columbia River plume. Surveys were conducted at night to target vertically migrating species, and community structure evaluated to better understand ecological interactions. Distinct inshore and offshore communities were identified during spring and summer that were correlated with ocean temperature, salinity, plume volume, and upwelling intensity. Resident euryhaline forage fish species, such as smelts, anchovy, herring, market squid, juvenile salmon, and spiny dogfish, showed a high affinity for inshore habitat and the lower salinity plume during spring. Highly migratory species, such as sardine, piscivorous hake, sharks, and mackerels, were associated with warmer, saltier waters offshore, during strong upwelling periods in summer. Overall, our study of pelagic nekton revealed that temporal dynamics in abundance and community composition were associated with seasonal abiotic phenomenon, but not interannual, large-scale oceanographic processes. Forage fish assemblages differed seasonally and spatially from the assemblages of major piscivorous predators. This finding suggests a potential role of the plume as refuge for forage fish from predation by piscivorous fish in the northern California Current.
Identification of Two Tobacco rattle virus Sequence Variants Associated with Virus-like Mottle Symptom on Hosta in Ohio
Authors: Fisher John R. 
Published: June 2013

Two Hosta sp. ‘So Sweet’ plants and one Hosta sieboldii (labeled as ‘Albo-marginata’) plant showing a suspected virus-like leaf mottle symptom tested negative for the Potyvirus group, Hosta virus X, Alfalfa mosaic virus, Arabis mosaic virus, Cucumber mosaic virus, Impatiens necrotic spot virus, Tobacco mosaic virus, Tobacco ringspot virus, Tomato ringspot virus, and Tomato spotted wilt virus by ELISA. DsRNA analysis produced a banding profile suggestive of a viral infection, and dsRNA was used as template to synthesize cDNAs for use with tobravirus group and Tobacco rattle virus (TRV) specific PCR primers. Amplicons were cloned and sequenced, and results showed two distinct populations of sequences: the two So Sweet isolates were ∼99% identical to each other but only ∼92% identical to the Albo-marginata isolate. These results represent the first confirmed report of TRV in Hosta in Ohio, and further demonstrate that there are at least two nucleotide sequence variants of the virus infecting Ohio Hosta.

A Quick and Simple Method to Evaluate Anisogramma anomala Ascospore Viability
Authors: Heckert Stephanie , Pscheidt Jay W. , Stone Jeff K. 
Published: June 2013

Viability of ascospores of Anisogramma anomala, cause of eastern filbert blight on European hazelnut, was assessed using the vital stain trypan blue (working solution of 0.05% in lactoglycerol). Viable ascospores only had faint blue staining around their cell walls while non-viable ascospores absorbed the stain and turned dark blue. The number of viable (non-stained) ascospores as determined by trypan blue was similar to the proportion of ascospores germinating on culture media. Viability of field collected ascospores from rainwater spore traps ranged from 41 to 68%. Disease incidence of hazelnut seedlings was more closely related to differences in ascospore abundance than to differences in ascospore viability. Accepted for publication 3 January 2013.

Climatic and Environmental Trends Observed During Epidemic and Non-epidemic Years of Soybean Sudden Death Syndrome in Iowa

Published: June 2013

Soybean yield losses due to sudden death syndrome (SDS) have varied from year to year in Iowa since the disease was first reported in 1993. An SDS epidemic in 2010 resulted in significant yield losses and raised numerous concerns by farmers and agronomists regarding the potential for future outbreaks. Since infection and SDS development is highly dependent on temperature and soil moisture, our hypothesis was that SDS epidemics occur in years with above-average rainfall and below-average temperatures. To test this hypothesis, environmental conditions in southeast and central Iowa were compared among epidemic and non-epidemic years. Mean total precipitation and number of days with precipitation during each month of the growing season (April through August) tended to be greater in epidemic years (10.4 to 26.3 inches, 10 to 15 days) than non-epidemic years (8.9 to 15.4 inches, 9 to 12 days). Soil temperatures in April through July averaged less in epidemic years (9.0 to 24.7°C) than non-epidemic years (10.4 to 26.6°C). The widespread 2010 SDS epidemic in Iowa likely resulted from the concurrence of several weather conditions that were particularly favorable for disease. To reduce risk of yield losses in future years, soybean farmers should use an integrated disease management for SDS, focusing on using resistant varieties, avoiding soil compaction, and avoiding planting in cool wet soils.

Authors: Hall Richard , Agarwal Renu , Green Roy 
Published: June 2013

PurposeThe purpose of this paper is to undertake a survey of the external and internal forces changing the nature of business schools and business education. It aims to investigate how management education responds to increasing productivity, innovation and capability challenges, examine how MBA programs currently meet these demands, and how these courses might redefine their identity and delivery and finally explore how to deepen engagement between business schools and business stakeholders, and to balance the imperatives of relevance and quality.Design/methodology/approachThis is a survey of business schools and business education in the context of evolving educational and industry policy in Australia in response to an increasingly international and competitive economy. The different potential roles and strategies of business schools are examined, and future strategies identified.FindingsThe paper finds that management education is facing insistent pressure to change internationally, and that business schools need to become more dynamic, innovative and responsive to succeed.Research limitations/implicationsThis survey considers the implications of recent policy on business education and relates this to emerging practice. Further research is required on how innovative pedagogical approaches will deliver more integrated and relevant business education.Practical implicationsThe paper defines key business school strategies, and outlines significant new approaches to making business education more innovative, responsive, integrated and engaged.Social implicationsThe paper considers means to more active stakeholder engagement for business schools.Originality/valueThe paper highlights the weaknesses of traditional business education strategy, and reveals the potential for significant change.
Diversity in the middle
Authors: Anderson Stephen E. 
Published: June 2013

PurposeThe purpose of this paper is to present the author's commentary on the special issue of Journal of Educational Administration entitled “Systemwide reform: examining districts under pressure”.Design/methodology/approachThe major thesis of this commentary and reflection on the preceding papers is that there is a need to recognize that “school districts” as known in the USA are examples of a more general phenomenon of intermediary organizational entities in education systems in North America and elsewhere in the world and that there is a need to problematize, not take for granted, the form, purpose, and influence of these mediating layers of the school system on the quality and improvement of schools, and on the implementation of government policies that are intended to regulate and support education in schools.FindingsThis issue of the Journal of Educational Administration presents a series of papers that highlight different aspects and contemporary trends in school district practice and research – organizational characteristics associated with district effectiveness (see Trujillo this issue), how districts are responding to political and public demands for accountability (see Hamilton et al., this issue), the invention of school district authorities as portfolio managers of diverse school provider systems (see Marsh et al., this issue), and how social communication networks linking school and district staff interface with the use of evidence to support school improvement (see Finnigan and Daly, as well as Wohlstetter and Smith this issue).Originality/valueThe simple thesis of this commentary is to argue that school districts function as an intermediate level of education governance, management, and support within national and state education systems, and that current research and discussion on the school district role in improving and sustaining the quality of education would be strengthened by broadening the scope of research and discussion to alternative kinds of intermediate level governance and support systems that exist in North America and in other regions of the world.
Dementia‐friendly communities: what the project “Creating a dementia‐friendly York” can tell us
Authors: Crampton Janet , Eley Ruth 
Published: June 2013

PurposeThis paper aims to outline the findings from a research and development project to determine how York might become a more dementia‐friendly city and, in drawing out the features, to discuss the benefits for other places.Design/methodology/approachThe project team worked with existing groups and individuals, including people with dementia and family carers, established a cross sector operational group formed of statutory and non‐statutory sectors, and developed a wider network to share news and ideas.FindingsYork as a city is already responding in many positive ways to the needs of people with dementia and their carers, but there is much more that can be done, there and elsewhere. The project proposes a model – People, Places, Networks and Resources – for analysing the suitability and helpfulness of existing arrangements or features of a place or an organisation in order to realise a more dementia‐friendly community.Research limitations/implicationsThe research was commissioned by and restricted to the City of York but there are lessons that can be taken and applied elsewhere. The project was also primarily concerned with the experience of people with dementia, generally post diagnosis, exploring their normal everyday lives as well as the contact they had and interventions from the statutory agencies. Reaching people with dementia who had not yet been diagnosed, or those on the margins of society, especially those living alone, proved hard to achieve.Practical implicationsThe numbers of people with dementia are expected to double over the next 30 years, with a shrinking of the working population and a tripling of costs to the NHS and social care. The proposed model can be applied anywhere to support the creation of dementia‐friendly communities that understand how to help.Social implicationsThe concept of “dementia‐friendliness” is not the exclusive domain of the health and social care world. On the contrary, the research reveals that it is the daily attrition of everyday life where help is most needed. People with dementia and family carers find routine activities most difficult – shopping, managing finances, using transport, keeping active – causing them to withdraw. There are moral, economic and business reasons why we should support people to live well with their dementia, as well as reasons of health and well‐being.Originality/valueThis project makes a substantial contribution to the literature on what constitutes a dementia‐friendly community and how to achieve it. It highlights the need for a wider information and awareness raising campaign for the general public and for anyone working directly with the public.
Giving kids a break: how surfing has helped young people in Cornwall overcome mental health and social difficulties
Authors: Taylor Joe 
Published: June 2013

PurposeThe paper aims to provide a summary of an innovative three‐year project that uses surfing as a health intervention for young people with emotional, social or mental health problems.Design/methodology/approachThe paper outlines the project which delivers six‐week surfing courses to 100 young people with mental health needs who are experiencing social exclusion. Participants’ levels of self‐confidence, self‐esteem and wellbeing were measured using pre and post wellbeing rating scales, along with feedback from clients and the people around them.FindingsThe intervention had a positive impact on the lives of participants. Average confidence and wellbeing scores rose over the six weeks. Some clients made significant improvements in managing their own behaviour and in achieving improved social inclusion. Examples of this cited in the paper include children at risk of school refusal who re‐engaged with school, and improvements to their behaviour at home or with peers.Research limitations/implicationsEvaluation interviews were undertaken by volunteers, not a professional evaluator.Social implicationsThe paper describes opportunities for health trusts and local authorities to explore surfing as a positive intervention for individuals experiencing mental health or social exclusion problems.Originality/valueThe paper highlights a highly innovative approach to re‐engaging young people which could be of value to health or local authority commissioners.
Market segmentation in the cell phone market among adolescents and young adults
Authors: J. Haverila Matti 
Published: June 2013

Purpose– The purpose of this study is to investigate the existence of inter-market market segments in the adolescents' and young adults' cell phone product-market in Finland, United Arab Emirates, Canada, China, and New Zealand. Drawing upon cell phone feature preferences criteria cited by Işıklar and Buyuközkan, the existence of inter-market market segments using these feature preferences as the cluster variate was examined.Design/methodology/approach– Using a survey questionnaire, data was gathered from 403 high school and 892 undergraduate students in Finland, UAE, China, Canada and New Zealand.Findings– The results of the study suggest the inter-market market segments do exist in the countries of this study, but their existence varies to some degree by country.Originality/value– An important implication of the research is the existence of the five inter-market segments among the adolescents and young adults in the five countries was established. Consequently, the inter-market segments extend over the borders. The five inter-market segments exist in all country markets except in New Zealand, which included only four segments. These five segments also appear to be unique and large enough in size, which are the key requirements in terms of successful segmentation, and thus warrant the development of unique products, services and marketing programs for the segments.
