Effects of Winter Feeding on Growth, Body Composition, and Processing Traits of Co-Cultured Blue Catfish, Channel Catfish, and Channel Catfish×Blue Catfish Hybrids
Authors: Bosworth Brian G 
Published: September 2012

Abstract
The effects of winter feeding on growth, body composition, and processing yield were compared for co-cultured blue catfish Ictalurus furcatus, channel catfish I. punctatus, and channel catfish×blue catfish hybrids. Fish (∼0.4–0.7 kg) from each genetic group were stocked communally at 5,625 fish/ha in ten 0.04-ha ponds during mid-November. Fish in five ponds were fed at 2% of initial body weight twice per week; fish in the other five ponds were not fed. The study was terminated after 14 weeks, and fish were weighed and processed. Analyzed traits were weight change (%), survival, and yields (%) of carcass, shank fillet, nugget, head, viscera, skin, intraperitoneal fat, liver, and ovary. Among fed fish, hybrids gained the most weight, channel catfish had intermediate weight gain, and blue catfish gained the least weight. Unfed blue catfish lost more weight than unfed channel catfish and hybrids. Survival was not different among genetic groups or between feeding regimes. Interactions among main effects for processing and body composition traits made generalizations difficult, but carcass yield was consistently higher for blue catfish and hybrids than for channel catfish, higher for females than for males, and higher for fed fish than for unfed fish. Shank fillet yield was higher for hybrids than for blue catfish and channel catfish, higher for females than for males, and higher for fed fish than for unfed fish. Nugget yield was higher for blue catfish than for channel catfish and hybrids and was higher for fed fish than for unfed fish. Blue catfish and hybrids had higher intraperitoneal fat yield and lower liver and ovary yield than channel catfish. Fed fish had higher intraperitoneal fat and liver yield than unfed fish. Winter feeding improved growth and fillet yield in all groups, but the benefits of winter feeding were lower for blue catfish than for channel catfish and hybrid catfish.

Abstract
Methratta, E.T., and Link, J.S. 2012. Feeding hotspots for four northwest Atlantic groundfish species. — ICES Journal of Marine Science, 69: 1710–1721. We used predator distribution and stomach content data to estimate the annual per capita rate of consumption for four representative predator species from the northwestern Atlantic Ocean, and considered how consumption is influenced by depth, bottom salinity, sediment grain size, location variables, and species-specific diet components. We found that geographic variables and species-specific prey resources were significantly associated with consumption rates, a pattern consistent with predator-prey theory. Prey categories comprised of fish were particularly important for a more mobile predator (silver hake Merluccius bilinearis), whereas benthic invertebrate prey were consistently important for a more sedentary predator (little skate Raja erinacea). Hotspots in consumption rates that overlap with particular prey resources were highlighted by the significance of location variables (longitude) for winter flounder Pseudopleuronectes americanus, silver hake, little skate, and sea raven Hemitripterus americanus. Depth was an important explanatory factor for consumption by little skate, but the explanatory value of abiotic habitat factors was low for the other three species. Greater emphasis on species-specific food habits, migratory patterns, and ecological interactions at the synoptic scales relevant to fisheries is needed for fisheries management.
Modelling perceived quality of tomato by structural equation analysis

Published: September 2012

PurposeThis paper aims to further progress in research on perceived quality of fresh fruit and vegetables. It seeks to develop and discuss two models for perceived quality of tomato, including the price variable as an indicator for perceived quality of tomato.Design/methodology/approachThe data come from a survey of 400 consumers that measures the importance of a set of tomato attributes on a Likert scale. The models were adjusted by means of structural equation analysis. Two procedures were followed for model development: the first started from an exploratory factor analysis. In the second, relations and correlations among variables were established starting from the theoretical framework that differentiates among search, experience and credence attributes.FindingsTwo models of tomato perceived quality are formulated and discussed. Both established that the perceived quality of fresh tomato could be explained through nine attributes. Some of them can be deduced at the place of purchase; some, during consumption while others are a question of trust. With regard to using price as an indicator of the perceived quality of tomato, both models suggested the elimination of this variable from the model for perceived quality.Originality/valueStudying perceived quality has received much attention in research on the behaviour of food consumers. Nevertheless, there are not many attempts to establish models for the perceived quality of fresh fruit and vegetables. Specifically, there are very few studies on consumer behaviour that analyse the perceived quality of tomato. Thus, this study is one of the first attempts to establish a model for perceived quality of tomato.

Published: September 2012

PurposeThe goal of this study is to examine the moderating effect of two group characteristics, group size and group cohesiveness, on the relationship between organizational commitment and transformational leadership, on the one hand, and in‐role and extra role behaviors, on the other. Based on social exchange theory, the main expectation was that the two group characteristics would create different conditions for exchange, influencing the relationship between determinants and outcomes.Design/methodology/approachThe sample was 223 Israeli employees from a variety of occupations (nurses, social workers, physiotherapists, laboratory employees, administrative staff, etc.) working in 31 medical units in two health care organizations (a response rate of 59 percent).FindingsHLM analyses showed strong moderating effects of both group cohesiveness and group size. The findings show that group characteristics strongly affect the nature and direction of the relationship between the examined determinants and the behavioral outcomes. The findings also revealed a significant three‐way interaction, demonstrating that group size and cohesiveness have an important joint effect. Cohesiveness differed in its effects on how commitment and transformational leadership are related to organizational citizenship behavior (OCB) and in‐role performance depending on whether the groups were large or small.Originality/valueThis study examines group size as a possible moderator, a construct only rarely considered in studies that attempt to predict OCB. The inclusion of leadership style is an important addition, considering that a good part of the exchange processes that take place in this context are between the employee and his/her supervisor.
HR attributions and the dual commitment of outsourced IT workers
Authors: Fontinha Rita , José Chambel Maria , De Cuyper Nele 
Published: September 2012

PurposeOutsourced information technology (IT) workers establish two different employment relationships: one with the outsourcing company that hires them and another with the client organization where they work daily. The attitudes that an employee has towards both organisations may be influenced by the interpretations or attributions that employees make about the reasons behind the human resource (HR) management practices implemented by the outsourcing company. This paper aims to propose that commitment‐focused HR attributions are positively and control‐focused HR attributions are negatively related to the affective commitment to the client organization, through the affective commitment to the outsourcing company.Design/methodology/approachThese hypotheses were tested with a sample of 158 highly skilled outsourced employees from the IT sector. Data were analyzed with structural equation modeling (SEM).FindingsThe paper's hypotheses were supported. It can conclude that, if an employee interprets the HR practices as part of a commitment‐focused strategy of the outsourcing company, it has clear attitudinal benefits. The study found that the relationship between HR attributions and the commitment to the client organization is mediated by the commitment to the outsourcing company.Practical implicationsThese findings hint at the critical role of outsourcing companies in managing the careers of these highly marketable employees.Originality/valueThis paper is the first to apply the concept of HR attributions to contingent employment literature in general and to outsourced IT workers in particular.
Outsourcing: mass layoffs and displaced workers' experiences
Authors: Michael Boniface , Michael Rashmi 
Published: September 2012

PurposeOutsourcing of information technology jobs outside the USA has resulted in social costs in the form of mass layoffs and displaced workers. The purpose of this paper is to show the social cost of outsourcing from a transaction cost economics (TCE) perspective.Design/methodology/approachThe paper analyses the incidences of mass layoffs in sectors prone to outsourcing and its consequences on displaced workers. Mass Layoff Statistics (MLS) and the Displaced Workers Survey (DWS) data generated by the Bureau of Labor Statistics (BLS), USA, between 1996 and 2010, are examined for this purpose.FindingsOutsourcing as a reason for mass layoffs has continued to persist up until 2010. Displaced workers experienced earnings losses after job losses and reemployment. The more educated workers had higher post displacement reemployment rates, while older persons suffered the most earnings losses.Research limitations/implicationsThe data pertain to the period 1996 to 2010, including the “Dot Com Bubble Bust” and the “Great Recession.” Changes in data collection methods by BLS over this time period makes it difficult to compare some of the data.Practical implicationsFor policy makers, managers and workers, this study focuses attention on the outsourcing by information technology dependent sectors and the accompanying social costs in the form of displaced workers.Originality/valueMost papers focus on the efficiency gains of outsourcing but this paper focuses attention on the social cost of outsourcing, which is under‐researched and often overlooked.
Strategic and tactical factors for successful ERP projects: insights from an Asian country
Authors: Dezdar Shahin 
Published: September 2012

PurposeThe purpose of this paper is to identify strategic and tactical factors that are crucial for the successful implementation of enterprise resource planning (ERP) systems. Although there are many factors that influence the success, the paper focuses on strategic factors, namely, top management support, project management, business process reengineering, and tactical factors, namely, enterprise‐wide communication, user training and education, and ERP vendor support.Design/methodology/approachThe study was conducted using a survey questionnaire. The questionnaires were distributed to ERP users in Iranian organizations and in total, 384 responses were collected and analyzed.FindingsA significant relationship was found between top management support, project management, enterprise‐wide communication, user training and education, and ERP vendor support with ERP implementation success. However, the relationship between business process reengineering and ERP implementation success was not supported.Originality/valueThis paper is one of the few that examine the success of ERP implementation from the perspective of key stakeholders (operational/unit/functional managers). It has contributed to academic research by producing empirical evidence to support the theories of critical success factors and ERP implementation success. The outcomes of this research are useful to ERP vendors and consultants to prepare some strategies to overcome the misfit between their ERP products and ERP adopting organizations in developing countries. Moreover, ERP adopting organizations and managers could gain an understanding of the complexities inherent in ERP installations to avoid barriers and increase the likelihood of achieving desired results.
Problematising the interplay between employment relations, migration and mobility
Authors: Rodriguez Jenny K. , Mearns Lesley 
Published: September 2012

PurposeThe purpose of this paper is to introduce the special issue by problematising labour agency, precariousness, and labour fragmentation as defining themes of the interplay between employment relations, migration and mobility.Design/methodology/approachDrawing from discussions about the impact of globalisation on changes in features of work and employment, and bringing together theory and research on employment relations and labour migration, the paper discusses the relational spatial and temporal nature of agency, the diverse features of worker experiences of precariousness, and the resulting fragmentation in labour solidarity.FindingsLabour agency, precariousness and labour fragmentation intersect to create the axis of dynamics of hardship and abuse that dominate work experiences of migrant workers in the global labour market. Globalisation has a pervasive impact in articulating and perpetuating systemic processes of closure, entrapment and containment, which are triggered by migration and legitimised by dynamics of employment relations.Originality/valueThe paper contributes to current discussions about the interplay between migration, mobility and employment relations and sets out future directions of research to enhance our understanding of the role of employment relations to perpetuate, legitimise and normalise dynamics of globalisation that promote the migrant division of labour and create contradictory labour demands and displacements in the global labour market.
Recognition of fabric density with quadratic local extremum
Authors: Wang Xiuchen , Li Xiaojiu 
Published: September 2012

PurposeThe purpose of this paper is to propose a new recognition algorithm on quadratic local extremum for fabric density recognition.Design/methodology/approachThe density wave is established to correctly detect density by searching local extremes. The gray wave of each line in fabric image is extracted first. The derivation of gray wave is calculated, extreme waves including all true extreme values and false extreme values are obtained. And then the second derivative of extreme waves are calculated and the result makes local correction. The density wave, which can represent position and quantity of yarn and interstice, is established. According to the resolution and size parameters of image, the function of density with density wave statistics is given.FindingsThe experiment and analysis proved that the method proposed can detect fabric density simply and successfully with less calculation and no image preprocessing.Research limitations/implicationsThe algorithm provides practical guidelines for fabric density detection and provides a new thought for fabric characteristic identification. Future work could be focused on the development of methods for the automatic algorithm with color fabrics.Originality/valueThe algorithm based on quadratic local extremum presented in this paper is a new method to successfully detect fabric density and can be applied to the recognition for other categories of clothing fabrics and images.
The joint effect of budgetary participation and broad‐scope management accounting systems on management performance
Authors: Cheng Min‐Tsung 
Published: September 2012

PurposeThe purpose of this paper is to examine the interaction effect of budgetary participation (BP) and broad‐scope management accounting systems (BMAS) on management performance (MP).Design/methodology/approachA survey questionnaire was administered to managers of listed electronics companies in Taiwan. A moderated multiple regression model containing a product term was used to examine the interaction effect among BMAS, BP, and MP.FindingsThe results show the presence of a non‐monotonic interaction relationship between BP and MP over the range of the extent of BMAS. These findings support the hypothesis that a high (low) perceived usefulness of BMAS information is correlated with MP in situations of high (low) BP.Originality/valueThe paper provides additional empirical evidence to make clear the nature of the interaction between BP and BMAS impacting MP. The empirical evidence presented in the paper reveals that BMAS plays an essential mediating role in the relationship between BP and MP. Firms implementing a BP system should pay particular attention to the fit collocation of both BMAS and BP.
How are women's glass ceiling beliefs related to career success?
Authors: Smith Paul , Caputi Peter , Crittenden Nadia 
Published: September 2012

PurposeThe purpose of this study is to test the concurrent criterion validity of a new measure, the Career Pathways Survey (CPS) by exploring how women's glass ceiling beliefs are related to five major indicators of subjective career success: career satisfaction, happiness, psychological wellbeing, physical health and work engagement (WE).Design/methodology/approachData from a cross‐sectional study of 258 women working in Australian organizations were analyzed. The participants completed the CPS and measures of subjective career success. The CPS assesses four sets of beliefs about glass ceilings: denial, resilience, acceptance and resignation.FindingsRegression analyses showed denial was positively associated with career satisfaction and WE; resignation was negatively related to happiness and both emotional and physical wellbeing; resilience had positive relationships with happiness and WE; acceptance was negatively related to WE. The findings provide support for the hypotheses and the concurrent validity of the CPS.Research limitations/implicationsGiven the study uses a cross‐sectional design, causal directions found between variables are inferences. Further research with longitudinal and experimental studies is needed to provide support for these inferences.Practical implicationsTraining programs to analyze glass ceiling beliefs after testing with the CPS may be a beneficial strategy to help women identify reasons for their career goals. Feedback from CPS testing might facilitate greater awareness of the causes of women's subjective success in organizations.Originality/valueThe paper is the first to shed light on the connections between these success variables and women's beliefs about glass ceilings.
Serbia brand identity: perspectives of residents and diaspora
Authors: Novčić Branka , Damnjanović Vesna , Popesku Mihajlo 
Published: September 2012

PurposeThe purpose of this paper is to identify, compare and contrast different perspectives of Serbian residents and diaspora regarding Serbia brand identity.Design/methodology/approachAttitudinal statements for research design of study were collected within a period of 12 months from national media (TV and newspapers) and ten focus groups. Multiple surveying techniques consisting of on‐the‐filed and on‐line surveys were applied. In total, 900 responses were collected and results were analyzed using principal component; also 740 examinees with Serbian citizenship and permanent residence in Serbia participated in the survey and 160 examinees from diaspora.FindingsFindings demonstrated that certain differences and similarities exist in the Serbia brand image perceptions between Serbian residents and diaspora. The first difference is reflected in the number of brand identity elements identified by each of the two examined groups. Diaspora identified four brand identity elements which are marked as mild nostalgia, business and pleasure destination, great cuisine and negative media bias; whilst residents identified six elements: people, obsolescence, negative media bias, cultural uniqueness, tourist destination and national treasure. The second difference, reflected in the mere content of the brand elements, is mainly determined by the fact that diaspora's perception is mainly influenced by the nostalgia, whilst residents’ perception is mainly influenced by national pride. These elements constantly interact to fulfil country brand promises to stakeholders.Research limitations/implicationsThe main constrains in this research study refer to small sample for diaspora and people living in Serbian countryside; people with a lower education are underrepresented.Practical implicationsThe study suggests guidelines for long‐term brand strategy development for Serbia as a brand. Different framework of destination brand identity from resident and diaspora perspective can be of immense use to brand planners for identification of problems for better brand positioning of Serbia as a country.Originality/valueThe research results emphasize perceptions of Serbia brand identity from resident and diaspora perspective and provide better understanding of the main components for communicating country branding strategy for Serbia. Both groups hold the view that Serbia suffers from negative media bias but still stays a recommendable tourist destination and a place to be.

Authors: Oberhofer Peter , Fürst Elmar 
Published: September 2012

PurposeThe purpose of this paper is to examine the status quo of environmental management in the Austrian road freight transport sector. Different environmental practices are analyzed and the influence of attitudes and firm size is evaluated.Design/methodology/approachA multi‐step empirical approach was performed. Based on a theoretical approach and a desktop survey on company web sites, several semi‐structured expert interviews were performed. Subsequently, an online‐survey was conducted and then analyzed by statistical methods.FindingsIt was found that although companies in the road freight transport sector are aware of the importance of sustainable issues, actual performance needs to be improved. The authors found significant differences, particularly between smaller and larger firms.Research limitations/implicationsDue to its nature as a research survey, the findings might be subject to some limitations such as sampling errors, non‐response effects and social desirability bias.Practical implicationsSmall to medium‐sized enterprises in particular will profit from a supportive framework which motivates to improve their environmental performance. Therefore, knowledge about specific ways of improvements and financial aids have to be provided.Originality/valueThe survey is a in‐depth analysis of the status quo of environmental management in the domain of road freight transport, taking into account differences between transport for hire or reward and transport on own account.
