Normal‐matrix‐based nonlinearH∞attitude tracking for spacecraft
Authors: Hong‐Yu Zhu 
Published: August 2010

PurposeThe purpose of this paper is to develop a novel nonlinearH∞control approach for the nonlinear multivariable attitude tracking of rigid spacecraft.Design/methodology/approachBased on the transformation of the attitude tracking problem into quaternion error stabilization, the feedback control law is developed by using the normal matrix control theory with the inverse‐additive perturbation description of systems uncertainties, and the Hamilton‐Jacobi‐Isaacs (HJI) partial differential inequality is employed for providing the nonlinearH∞control criteria for the proposed control law. The onboard recursive least squares (RLS) estimation algorithm of inertia tensor is used for the further improving of the normal matrix property of the control system. The RLS algorithm is simple enough for the spacecraft borne computer. Computer simulation is performed to demonstrate the effectiveness of the control law proposed.FindingsBy the normal matrix control theory, the nonlinearH∞control law for attitude tracking is developed without solving the HJI inequality and with the inflight estimation of inertia, the proposed control law is adaptive and robust to the variation of mass properties, and its normality is further improved.Research limitations/implicationsThe paper is limited in rigid spacecraft with slowly changing mass property. The flexible influences are not considered.Practical implicationsThe paper provides an alternative to the spacecraft researchers/engineers for developing the robust attitude control law with a simple structure and self‐tuning ability.Originality/valueThe paper is the first to provide a robust control based on the normal matrix approach, the HJI inequality, and the estimation of inertia.
Antioxidant contents of pre‐packed fresh‐cut versus whole fruit and vegetables
Authors: Linus Opara Umezuruike , Al‐Ani Majeed R. 
Published: August 2010

PurposeThe purpose of this paper is to evaluate the difference in antioxidant contents of pre‐packed fresh‐cut and whole fruit and vegetables as sold in the market.Design/methodology/approachSamples of pre‐packed fresh‐cut fruit and vegetables as well as whole produce were collected from the market in Muscat and Oman, and analyzed for vitamin C, lycopene and total carotenoids. Analysis of variance was carried out to determine the level of statistical differences between fresh‐cut and whole fruit and vegetables.FindingsIn both fruit and vegetables, vitamin C contents are higher in whole than fresh‐cut produce, with greater reductions in vitamin C contents of fresh‐cut vegetables than fruit. In both fresh‐cut and whole fruit, lycopene content is 30‐36 times higher in watermelon than the contents of other fruit genotypes studied. Similarly, total carotenoids content of watermelon is six to 21 times higher than other types of fruit studied. Both lycopene and total carotenoids content are higher in whole than fresh‐cut fruit, except in pineapple fruit. In both fresh‐cut and whole vegetables, lycopene content of carrot is three to four times higher than cucumber, and four to six times higher than celery. Implications of these results on public health policy are discussed.Originality/valuePrevious studies on quality of fresh‐cut produce are based on controlled experimental studies using samples of produce from the same batch to compare fresh‐cut versus whole produce. However, consumers in retails stores often have to make a choice between pre‐packed fresh‐cut or whole (un‐cut) produce, which are not usually from the same source or batch. It is therefore essential to understand the differences in nutritional value of whole and pre‐packed fresh‐cuts sold in the market.
Effects of cooking methods on carotenoids content of Omani kingfish (Scomeberomorus commersonL.)
Authors: Linus Opara Umezuruike , Al‐Ani Majeed R. 
Published: August 2010

PurposeFish is subjected to different methods of preparation and a major challenge facing consumers is maintaining and preserving the nutritional quality of cooked fish. This paper aims to examine the effects of different cooking methods (baking, boiling, deep‐frying, pan‐frying, microwaving and grilling) on total carotenoids and lycopene content in muscle and skin fractions of Omani kingfish.Design/methodology/approachFresh, commercially harvested kingfish samples were purchased from a supermarket and prepared using six commonly used cooking methods. Raw fish samples were used as control. Muscle and skin fish portions for each cooking method and raw samples were analyzed for total carotenoids and lycopene contents.FindingsThe paper finds that cooking methods affected kingfish skin and muscle differently. The positive effects of cooking methods on kingfish muscle scored from high to low are as follows for total carotenoids content: grilling, microwaving, pan‐frying, boiling, deep‐frying and baking; and grilling, microwaving, boiling, deep‐frying, baking and pan‐frying for lycopene content. Baking resulted in the highest increase in both total carotenoids and lycopene contents in the skin, followed by grilling and pan‐frying for total carotenoids. In conclusion, grilling, followed by microwaving, is finds to be the best cooking method for high‐carotenoids content and healthy eating of kingfish.Originality/valueThis is the first paper to be reported on the effects of different cooking methods on total carotenoids content (including lycopene) in skin and muscle of kingfish caught in the warm waters of the Gulf of Oman.
The impact of power on information sharing in the Finnish food industry
Authors: Kähkönen Anni‐Kaisa , Tenkanen Mari 
Published: August 2010

PurposeThe paper aims to analyze power balance and collaboration in the value net context and to discuss the role of information as a source of power. The purpose is to find out how power affects information sharing and collaboration between buyers and suppliers. Both demand and supply perspectives are utilized, and the value net approach is combined with research on supply management and market orientation.Design/methodology/approachThe case study method was used in order to analyze relationships and information sharing in the Finnish food industry. A 29 semi‐structured interviews were conducted in four case companies.FindingsThe results indicate that value net actors in the supplier role are willing to form collaborative relationships, but when they are in the role of the buyer the willingness to collaborate weakens. The implication is that power increases as the distance from the end‐markets decreases and that power relations affect collaboration and restrict information sharing between the actors in the value net.Research limitations/implicationsA single case study such as this does not purport to produce findings that can be generalized in a statistical sense, but the findings will be valuable in an analytical sense because they extend understanding of the existing theory. Further research should be directed towards comparative studies of value nets, power relations and information sharing in other countries and in other industries.Practical implicationsThe paper sheds light on the critical factors that influence value net collaboration, making it possible for managers to focus on relevant issues when developing business relationships and the value net as a whole.Originality/valueThere is a limited amount of research on value nets in the food industry, and because of the changing business environment there is an urgent need for studies focusing on the food business in the context of networks and value nets. In combining the value net approach with purchasing and supply management and market orientation perspectives the study extends the discussion on information sharing with its emphasis on network relations and the complicated nature of collaboration.
Tracking down trends in non‐meat consumption in Finnish households, 1966‐2006
Authors: Vinnari Markus , Mustonen Pekka , Räsänen Pekka 
Published: August 2010

PurposeThe paper aims to examine changes in household consumption behaviour through an empirical investigation of the decision to consume meat, to not consume meat or to consume only small amounts of meat. The goal is to find out if the decision not to consume meat is becoming more prevalent, and to understand in what social categories this is happening, if any. A further aim is to investigate whether meat consumption is strongly associated with gender on the household level.Design/methodology/approachExpenditure survey data gathered from Finland during the last 40 years was used to identify what kinds of changes were taking place in the consumption of meat and meat products. The independent measures include six variables: the gender of the highest earner in the household (HEH), the type of household, the type of municipality and the income quintile, educational level and age of the HEH. The size of the samples varied between 2,986 and 8,258 households.FindingsThe analysis revealed that the decision not to consume meat became prevalent in Finland at the end of the 1970s but the growth rate has somewhat stabilised during recent decades. The gender of the HEH affects the family meat consumption. As non‐meat consumption has become more widespread it has also more clearly become a middle‐class phenomenon.Originality/valueThere are no previous studies available on the development of non‐meat consumption from this long‐term perspective.
Biscuit (cookie) consumption
Authors: McIntyre Charles , Schwanke Benita 
Published: August 2010

PurposeThe aim is to investigate the choice and experience attributes of core – sweet (cookie) and savoury (cracker) – biscuits of a high premium, luxury or indulgent nature to investigate the possible opportunity for organic or other more healthily perceived product option developments.Design/methodology/approachThe approach taken is a qualitative focus group study involving a series of core user adult consumer groups, aged between 25 and the late 1960s, in a southern county of the UK.FindingsThe adult consumption of biscuits involves a process that aspires towards an overall “better‐life”, sensual experience by momentarily escaping the everyday realm and aiming to emulate either a perceived “real” or a mythical, largely past‐related style of existence. This is often associated with meanings inherent in the terms “natural”, “rural”, “home‐baked” and “traditional” as well as “elegant” associations and production and selling agency values around small or local, pre‐modern source structures. Organic labelling is found to have a negative “horn” effect to buyers by countering other desired associations.Research limitations/implicationsThe study used a small sample in the county of Dorset in the south of England, but these are implications for new product development and marketing of luxury snacks.Practical implicationsAlternative areas of marketing focus to rational appeal are suggested that could help promote healthier biscuit choice options.Originality/valueIrrational ideal and unreal aspects of consumer appeal are found to feature the creation of imagined or re‐created “moments of perfection” in a process of cognitive suspension.
Origin vs organic in Manchego cheese: which is more important?
Authors: Bernabéu Rodolfo , Díaz Mónica , Olmeda Miguel 
Published: August 2010

PurposeThe paper aims to measure the degree of influence that attributes such as price, origin, type and production system have on Spanish consumers when purchasing cheese, while also analysing various cheese differentiation strategies.Design/methodology/approachThe methodology consisted in a survey of 420 Madrid (Spain) cheese consumers during the month of December 2006, whose preferences were determined through several multivariate techniques.FindingsThe first result derived from this paper is the negative influence of the organic production system attribute on the cheese consumer preference structure. Therefore, this attribute becomes an inadequate differentiation strategy for cheese, while origin is the most adequate differentiation. In this sense, three consumer segments are identified: the first, shops for cheese mainly by type, the second, by a combination of origin, type and price and the third, by an origin of cheese. In this sense, except for the first segment, where competition by a type of cheese from other places could endanger the local market, possible strategies would be to continue emphasizing origin in a traditional approach.Originality/valueThe paper highlights organic differentiation in products already differentiated and accepted by the consumer does not always contribute additional utility to the consumer. It does not matter whether this differentiation and acceptance comes from origin and/or traditional production, as is the case of Manchego cheese.
Web 2.0 and the library: a transformational technology?
Authors: Joint Nicholas 
Published: August 2010

PurposeThis paper is the final one in a series which has tried to give an overview of so‐called transformational areas of digital library technology. The aim has been to assess how much real transformation these applications can bring about, in terms of creating genuine user benefit and also changing everyday library practice.Design/methodology/approachThe paper provides a summary of some of the legal and ethical issues associated with web 2.0 applications in libraries, associated with a brief retrospective view of some relevant literature.FindingsAlthough web 2.0 innovations have had a massive impact on the larger World Wide Web, the practical impact on library service delivery has been limited to date. What probably can be termed transformational in the effect of web 2.0 developments on library and information work is their effect on some underlying principles of professional practice.Research limitations/implicationsThe legal and ethical challenges of incorporating web 2.0 platforms into mainstream institutional service delivery need to be subject to further research, so that the risks associated with these innovations are better understood at the strategic and policy‐making level.Practical implicationsThis paper makes some recommendations about new principles of library and information practice which will help practitioners make better sense of these innovations in their overall information environment.Social implicationsThe paper puts in context some of the more problematic social impacts of web 2.0 innovations, without denying the undeniable positive contribution of social networking to the sphere of human interactivity.Originality/valueThis paper raises some cautionary points about web 2.0 applications without adopting a precautionary approach of total prohibition. However, none of the suggestions or analysis in this piece should be considered to constitute legal advice. If such advice is required, the reader should consult appropriate legal professionals.

Authors: Kuei Huang Yun , Yang Wen I. 
Published: August 2010

PurposeThe purpose of this paper is to understand the effect of internet book reviews on reader borrowing intention.Design/methodology/approachThe study used www.yumau.com, www.ptt.cc and the bulletin board system on www.lib.ntou.edu.tw to post announcements, soliciting 33 readers who had browsed internet book reviews to identify books to borrow. Then, using a content analytic method to analyze interview content, an investigation was conducted on the effect of internet book reviews, numbers of references and content of internet book reviews on reader borrowing intention.FindingsThese results revealed that numbers of references and content of internet book reviews play an important role in borrowing intention.Practical implicationsThese results can provide librarians with a reference for promoting book‐borrowing activities. They can also provide internet bookstores with a reference for managing their book reviews.Originality/valueElectronic word‐of‐mouth reviews have become an important guide to reader borrowing intention. The study investigates readers' thoughts on internet book reviews and their effects, and advances several management suggestions.
Science vs social science
Authors: Sheeja N.K. 
Published: August 2010

PurposeThe purpose of this paper is to examine the information‐seeking behavior of science and social science research scholars, including service effectiveness, satisfaction level on different type of sources and various methods adopted by the scholars for keeping up to date.Design/methodology/approachData were gathered using a questionnaire survey of 200, randomly selected, PhD students of science and social science departments of four universities in Kerala, India.FindingsAlthough similarities exist between social science and science PhD students with regard to information‐seeking behavior, there are significant differences as well. There is a significant difference between science and social science scholars on the perception of the adequacy of print journals and database collection which are very relevant to the research purposes. There is no significant difference between science and social science scholars on the perception of the adequacy of e‐journals, the most used source for keeping up to date. The study proved that scholars of both the fields are dissatisfied with the effectiveness of the library in keeping them up to date with latest developments.Originality/valueThe study is based on actual situation and the result can be used for library service redesign for different types of users.
The grounding of the “flying bank”
Authors: Hermann Aaron , Rammal Hussain G. 
Published: August 2010

PurposeThe purpose of this paper is to demonstrate the importance of effective, knowledgeable and accountable management and board structures in business organisations. Using the case of Swissair, the paper aims to demonstrate the importance of competent industry knowledgeable executive boards, with regard not only to company profits and sustainability but also to stability and socially responsible decision making.Design/methodology/approachAn explanatory and descriptive case study approach was undertaken utilising historical data and literature‐based information and research on Swissair. The analysis of the case is guided by the use of the Resource Dependence and Group Conformity theories.FindingsThe findings suggest that the alliance and acquisition strategy pursued by Swissair's management and the lack of leadership and accountability by the CEO and Chairman of the board were the main contributing factors to the company's collapse.Practical implicationsThe implications include impacts on the way in which European organisations are governed and the composition of the management teams and Board of Directors. Additional implications include changes to the legislation in Europe, more specifically Switzerland and the European Free Trade Alliance, aimed at the prevention of similar future collapses.Originality/valueThe paper's originality stems from the application of decision making and group theory, coupled with corporate governance ideas applied in a practical sense to the contemporary case of Swissair in a manner previously not considered, to demonstrate the importance of effective, knowledgeable and accountable management and board structures in organisations. Value is demonstrated with the recent issues experienced by Austrian Airlines and its subsequent acquisition by Lufthansa, indicating a need to address the corporate governance requirements in the European airline industry.
Corporate mission, corporate policies and business outcomes: evidence from Japan
Authors: Hirota Shinichi , Kubo Katsuyuki , Miyajima Hideaki , Hong Paul , Won Park Young 
Published: August 2010

PurposeThis study sets out to explore questions such as: “Does mission statement matter? If so, in what ways?” Using data on mission statements of 128 large Japanese firms, the paper aims to show that corporate mission has a significant impact on corporate policies that determine employment, board, and financial structures.Design/methodology/approachThe paper provides evidence that strong‐mission firms are more likely to retain incumbent employees, promote managers from within firms, and have less debt and a higher percentage of interlocking shareholdings than weak‐mission firms.FindingsThe evidence supports the view that strong‐mission firms value their organizational capital and thus tend to adopt policies to preserve it. It also confirms that corporate mission and its embedded policies contribute to better corporate performance. The paper suggests that the effect of explicit corporate mission and its implementation has practical impacts in corporate policies and business outcomes.Research limitations/implicationsThe sample is based on firms from Japan. The criteria used to discriminate between strong mission and weak mission firms need further refinement with more rigorous sub‐dimensions. In the Japanese context the percentage of inside directors is an important indication of internally promoted managers – one might argue that a measure of external pressures (e.g. law, codes, investors, etc.) might be a better one. The small number of cases and the richness of statements need a richer qualitative analysis in the future.Practical implicationsThe empirical results provide helpful insight on the organizational behavior of Japanese firms during the long economic downturn from the 1990s to 2000s in Japan and an insight on what to do in view of the challenges facing Japanese firms.Originality/valueThe paper presents a model that clarifies the role of mission statement. The extensive literature review includes a diverse set of papers on the role of mission statement. The empirical results suggest how strong Japanese corporate mission, expressed in mission statements, might have impact on corporate outcomes through the formation and utilization of Monozukuri.

Authors: Aerenhouts Dirk , Hebbelinck Marcel , De Vriese Stephanie , Clarys Peter 
Published: August 2010

PurposeThe purpose of this paper is to describe health‐related factors and behaviors associated with soy consumption and to present a better identification of a soy consumer's profile at meso‐level.Design/methodology/approachA total of 104 women and 49 men, 22‐77 years old and employed at the Vrije Universiteit Brussel, participated in the study. A physical activity questionnaire and a food frequency questionnaire were administered. Body height, weight, waist and hip circumferences, body fat percentage (2‐pole BIA), blood glucose and total blood cholesterol were measured in a fasting state.FindingsCompared with the general population, the sample showed healthier eating habits (breakfast frequency, fruit and vegetable consumption) and lower prevalence of smoking. Women regularly consuming soy had lower waist circumference, body fat percentage and total cholesterol levels than infrequent soy consumers. Men consuming soy foods regularly participated significantly more in high‐intensity physical activities and consumed less meat, poultry and fish.Research limitations/implicationsOwing to recruitment in a university setting, a healthy volunteer effect and socio‐economic bias may exist. Therefore, generalization of the results is not possible and interpretation of the results must be performed with the utmost caution.Practical implicationsIt can be concluded that, especially in men, soy consumption fits in a healthy lifestyle.Originality/valueRegular soy‐consuming women differed from infrequent soy‐consuming women on anthropometrics and cholesterol, while regular consuming men differed behaviorally from infrequent soy‐consuming men. Overall, regular soy consumers were generally more health‐conscious and had better health outcomes.
