Selected AbstractsUsing the Weapons You Have: The Role of Resources and Competitor Orientation as Enablers and Inhibitors of Competitive Reaction to New Products,THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 2 2010Marion Debruyne It is a well-accepted notion that to respond to competitive attacks firms need the necessary resources to do so. However, the presence of resources may not be a sufficient condition to enhance competitive responsiveness. Following a managerial decision-making approach, the present paper investigates how the availability of resources affects decision makers' assessment of a competitor's new product and their subsequent reaction to it. This study posits that competitive reaction follows from a decision maker's assessment of a competitive action. This assessment contains a motivation dimension and an ability dimension. The effect of three types of resources,financial, marketing, and technological,are examined. A quasi-experiment with the Markstrat business game as an empirical setting provided 339 questionnaires containing information on 29 different new product introductions. The motivation and ability dimensions are confirmed as important antecedents explaining reaction behavior. The results show that resources possess a dual, and opposing, role in influencing competitive reaction to new products. On the one hand, resources enhance decision makers' belief that they are able to react effectively to competitive attacks, but the presence of resources also makes them less motivated to react. The paper introduces two explanations for this: the liability-of-wealth hypothesis and the strong-competitor hypothesis. The addition of competitor orientation as a moderator allows us to discern between the two competing rationales for the existence of a negative effect of resources on the expected likelihood of success of a competitive new product introduction, supporting the liability-of-wealth hypothesis. The paper demonstrates the key role of competitor orientation and formulates implications from that. [source] The Impact of Communication Strategy on Launching New Products: The Moderating Role of Product InnovativenessTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 1 2003Yikuan Lee Academic literature is filled with debate on whether product innovativeness positively impacts new product performance (NPP) because of increasing competitive advantage or negatively impacts performance due to consumers' fears of novel technology and resultant resistance to adopt. This study investigates this issue by modeling product innovativeness as a moderator that influences the relationship between communication strategy and new product performance. The authors emphasize that the impact of innovativeness to producers is different from that to consumers and that the differences have strategic impact when commercializing highly innovative products. Product innovativeness is conceptualized as multidimensional, and each dimension is tested separately. Four dimensions of innovativeness are explored,product newness to the firm, market newness to the firm, product superiority to the customer, and adoption difficulty for the customer. In this study, communication strategy is comprised of preannouncement strategy and advertising strategy. First, the relationship between whether or not a preannouncement is offered and NPP is explored. Then three types of preannouncement messages (customer education, anticipation creation, and market preemption) are investigated. Advertising strategy is characterized by whether the advertisement campaign at the time of launch was based primarily on emotional or functional appeals. Using empirical results from 284 surveys of product managers, the authors find that the relationship between communication strategy and NPP is moderated by innovativeness, and that the relationships differ not only by degree but also by type of innovativeness. Implications for research and practice are discussed. [source] EXTENDING SHELF LIFE OF FRESH-CUT PERSIMMON BY HONEY SOLUTION DIPSJOURNAL OF FOOD PROCESSING AND PRESERVATION, Issue 1 2010MUHARREM ERGUN ABSTRACT Ripe persimmon fruit (Diospyros kaki L) cv. "Hachiya" were diced, then treated with 10,20% w/v diluted honey solution or water as the control, followed by cold storage at 4C until loss of acceptable quality. The persimmon cubes were subject to assessments during the storage of organoleptic and visual quality, softness and exuding juice, soluble solids content (SSC), and absorbance at 436, 440, 675 and 760 nm, respectively. Honey treatments prevented off-aroma development and delayed jelling. Softness and exuding juice of the fresh-cut persimmon cubes increased with time, with the increase in both parameters being significantly suppressed by honey solution dips. Changes in SSC, pH and the absorbance at 436, 440, 675 and 760 nm, respectively, during storage were minor and there was little effect of the honey treatments on these parameters. Overall, the shelf life of fresh-cut persimmon cubes was extended by honey solution dips, which delayed off-aroma development, firmness loss and jelling. PRACTICAL APPLICATIONS New products and changing trends make today's food marketplace alive, and fresh-cut fruits and vegetables seem to be on top of list of these products. Although fresh-cut produce has been on the market for a long time, preserving their quality attributes has not been completely successful especially in the case of fruit. This study focuses on a new alternative fresh-cut produce, fresh-cut persimmon, with adapting a potentially safe organic method, use of honey dips. The present study demonstrated that honey solution dip treatments could preserve the fresh-like quality of typical flavor or aroma of persimmon fruit by causing no changes in aroma and taste attributes and extending shelf life. Therefore, honey dip treatment may be used, depending on commodity, to preserve and extend shelf life of fresh-cut produce in fresh-cut processing industry. [source] Latest news and product developmentsPRESCRIBER, Issue 21 2008Article first published online: 2 DEC 200 Osteoporosis guideline A new guideline on the management of osteoporosis in men over 50 and post-menopausal women has been published by the National Osteoporosis Guideline Group (www.shef.ac.uk/NOGG), a group of organisations representing health professionals and patients, with funding from several pharmaceutical companies. The guideline recommends using the FRAX tool (www.shef.ac.uk/FRAX) to assess the 10-year fracture risk in individuals with risk factors to facilitate targeting DXA scans to measure bone mineral density. Patients who have already sustained a fragility fracture should be treated without risk assessment. Treatment recommendations are similar to those published in draft NICE guidance on primary and secondary prevention, selecting alendronate as the drug of first choice for most patients. Efalizumab efficacy A multicentred postapproval trial has demonstrated long-term efficacy and a favourable safety profile for efalizumab (Raptiva) in moderate to severe chronic plaque psoriasis. The CONTROL II study, presented in September at the 17th EADV congress in Paris, was conducted at 170 sites in 18 European countries and involved 1255 patients who had failed to respond to traditional systemic therapies. In this non-blinded study, 68 per cent of participants achieved the primary efficacy end-point and showed improvement within the first 12 weeks; control was maintained in responding patients who continued treatment. Adverse effects were graded as mild or moderate and similar to those reported in earlier studies. There was no evidence of an increase in malignancies or infections. New oral anticoagulant Rivaroxaban (Xarelto), an oral factor Xa inhibitor, has been introduced for the prevention of venous thrombo-embolism in patients undergoing elective hip or knee replacement surgery. Compared with the low molecular weight heparin enoxaparin (Clexane), rivaroxaban has been shown to reduce the risk of venous thrombosis by 70 per cent after hip replacement and by 49 per cent after knee replacement; the risk of bleeding was similar. At the recommended dose of 10mg once daily, prophylaxis after hip surgery lasts five weeks and costs £157; prophylaxis after knee surgery lasts two weeks and costs £63. New products UCB Pharma has introduced lacosamide (Vimpat) as adjunctive treatment of partial-onset epilepsy with or without secondary generalisation in patients aged 16 and over. A month's treatment at the recommended maintenance dose of 100-200mg twice daily costs approximately £73-£140. A new non-nucleoside reverse transcriptase inhibitor (NNRI) is available for the treatment of HIV-1 infection in combination with a boosted protease inhibitor (PI) and other antiretrovirals in treatment-experienced adults. Etravirine (Intelence) costs approximately £320 for one month's treatment at the recommended dose of 200mg twice daily. Voltarol Pain-Eze (diclofenac) 12.5mg tablets are now available without prescription; a pack of 18 tablets costs £5.99. Atypicals and EPS risk Atypical antipsychotics are not associated with a significantly lower risk of extra-pyramidal symptoms than first-generation agents such as perphenazine (Fentazin), a new analysis of the CATIE study has shown (Br J Psychiatry 2008;193:279,88). CATIE was a large trial comparing the efficacy and safety of antipsychotics in the treatment of schizophrenia in which perphenazine was a representative first-generation agent (Am J Psychiatry 2006;163:611,22). This analysis found no differences in the risk of parkinsonism, dystonia, akathisia or tardive dyskinesia between perphenazine and the newer antipsychotics; use of antiparkinsonian medication was higher with risperidone and lower with quetiapine (Seroquel). Mental health website A new website offering information about mental illnesses and drug treatment has been launched by the United Kingdom Psychiatric Pharmacy Group (UKPPG), the College of Mental Health Pharmacists (CMHP), the Pharmaceutical Schizo-phrenia Initiative (PSI) and the National Institute for Mental Health in England (NIMHE). www.choiceandmedication.org.uk includes information about 17 mental illnesses and a large number of drug treatments. It offers links to other sites offering information and downloadable leaflets, help to identify the local mental health trust and downloadable charts comparing treatments for each indication. [source] Functional Management Competence and Growth of Young Technology-Based FirmsCREATIVITY AND INNOVATION MANAGEMENT, Issue 3 2008Sören Salomo Acknowledging an increased research interest into the success factors for young technology-based firms in the last decade, the present study serves two main purposes. First, we aim at developing a comprehensive concept of functional management competence in young technology-based firms. Functional management competence covers the understanding of and proficiency in managing specific functional tasks (Katz, 1974). As we focus on young technology-based firms, it is suggested that marketing, financial and technology management tasks are at the core of functional management competence. Second, we aim at delineating and validating an appropriate measurement model for functional management competence. In order to test the model's nomological validity, we investigate the impact of functional management competence on firm growth. Therefore, building on established firm development approaches, we propose a phase model for the development of young technology-based firms. Our study builds upon data from 212 young technology-based firms in the field of microtechnology, nanotechnology, electronics, optics and lasers. We use formative measurement models to establish valid and reliable constructs and a path model based on partial least squares modelling to investigate the performance effects. The results suggest that functional management competences generally are significant drivers of firm development speed. In particular, technology and marketing management competences are shown to impact development speed. While technology management competence is positively driving development speed, the marketing management competence impact on speed is mediated by competitive advantage of the new products developed by young technology-based firms. Financial management competence has no significant link to firm development speed. [source] Managing Risks in Multiple Online Auctions: An Options Approach,DECISION SCIENCES, Issue 3 2005Ram Gopal ABSTRACT The scenario of established business sellers utilizing online auction markets to reach consumers and sell new products is becoming increasingly common. We propose a class of risk management tools, loosely based on the concept of financial options that can be employed by such sellers. While conceptually similar to options in financial markets, we empirically demonstrate that option instruments within auction markets cannot be developed employing similar methodologies, because the fundamental tenets of extant option pricing models do not hold within online auction markets. We provide a framework to analyze the value proposition of options to potential sellers, option-holder behavior implications on auction processes, and seller strategies to write and price options that maximize potential revenues. We then develop an approach that enables a seller to assess the demand for options under different option price and volume scenarios. We compare option prices derived from our approach with those derived from the Black-Scholes model (Black & Scholes, 1973) and discuss the implications of the price differences. Experiments based on actual auction data suggest that options can provide significant benefits under a variety of option-holder behavioral patterns. [source] Measuring Market Power in the Ready-to-Eat Cereal IndustryECONOMETRICA, Issue 2 2001Aviv Nevo The ready-to-eat cereal industry is characterized by high concentration, high price-cost margins, large advertising-to-sales ratios, and numerous introductions of new products. Previous researchers have concluded that the ready-to-eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense nonprice competition. This paper empirically examines this conclusion. In particular, I estimate price-cost margins, but more importantly I am able empirically to separate these margins into three sources: (i) that which is due to product differentiation; (ii) that which is due to multi-product firm pricing; and (iii) that due to potential price collusion. The results suggest that given the demand for different brands of cereal, the first two effects explain most of the observed price-cost margins. I conclude that prices in the industry are consistent with noncollusive pricing behavior, despite the high price-cost margins. Leading firms are able to maintain a portfolio of differentiated products and influence the perceived product quality. It is these two factors that lead to high price-cost margins. [source] A question of balance: prioritizing public health responses to harm from gamblingADDICTION, Issue 5 2009Peter J. Adams ABSTRACT Aim To provide an overview on the nature and importance of public health approaches to the global expansion of commercial gambling. Method Three key areas of public health activity are examined: harm minimization, health promotion and the political determinants for change. Findings The rapid proliferation of gambling experienced in many countries is driven by the commercial development of new products orientated around continuous and rapid mass consumption. This is particularly the case with ongoing refinements to electronic gambling machines and the development of new gambling technologies using the internet and mobile telephones. So far responses to negative impacts have, on the whole, focused upon individualized treatment interventions. A public health approach to gambling offers a broad range of strategies to tackle the wider implications of gambling expansion: harm reduction provides evidence-based strategies for managing identifiable harm; health promotion focuses upon communities building their capacity, knowledge and resilience with regard to the attractions of gambling, and action on the political determinants sets out to increase the accountability and reduce the conflicts of interest that influence government resolve in managing their gambling environments. Conclusion In this new environment of mass consumption, efforts in developing treatment responses to problem gambling need to be balanced with, at least, equal efforts in developing public health responses. With the expansion of commercial gambling occurring globally, international agencies could play a critical role in supporting public health initiatives. [source] Oxidative mutagenicity of polar fractions from polycyclic aromatic hydrocarbon,contaminated soilsENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 11 2008Joanna Park Abstract Soils at hazardous waste sites contain complex mixtures of chemicals and often are difficult to characterize in terms of risk to human and ecological health. Over time, biogeochemical processes can decrease the apparent concentrations of pollutants but also can lead to accumulation of new products for which toxicity and behavior in the environment are largely unknown. A bioassay-directed fractionation technique was used to assess the contribution of redox-active bacterial metabolites to the toxicity of soil contaminated with polycyclic aromatic hydrocarbons (PAHs). A reverse mutation assay with Escherichia coli WP2 uvrA/pKM101 (IC188) and E. coli WP2 uvrA oxyR/pKM101 (IC203) was used to screen fractions for genotoxicity. Strain IC203 carries the ,oxyR30 mutation, which prevents the expression of antioxidant proteins in response to oxidative stress and increases its reversion by compounds that generate reactive oxygen species (ROS). Polar fractions of PAH-contaminated soil extracts were mutagenic to strain IC203 but not to strain IC188, suggesting the involvement of ROS in genotoxicity. Genotoxic potencies ranged from 300 to 1,700 revertants per milligram of fraction. Catalase was able to decrease IC203 reversion, implicating the involvement of hydrogen peroxide as a key ROS. Oxidized PAH compounds, including quinones, were identified in the mutagenic fractions but were not by themselves mutagenic. Deasphalted whole extracts and recombined fractions were not mutagenic, indicating that interactions between compounds in different fractions can mitigate genotoxicity. [source] Physical-chemical characteristics and oxidative stability of oil obtained from lyophilized raspberry seedEUROPEAN JOURNAL OF LIPID SCIENCE AND TECHNOLOGY, Issue 11 2009Aleksandra, urovi Abstract Fresh raspberry (Rubus idaeus), cultivar Willamette, was freeze-dried (lyophilization). A byproduct of lyophilization is "fine dust" of raspberry consisting of finely ground raspberry fruit body and seed. The seeds were separated. The seed oil was isolated and its physical and chemical characteristics were determined. Parameters that characterize the seed and quality of the oil were examined, including fatty acid composition, oxidative stability under different storage conditions, and radical-scavenging activity. The fatty acid composition was determined by GC/FID and the contents of the dominant fatty acids were found as: oleic 16.92%, linoleic 54.95%, and ,-linolenic acid 23.97%. The oxidative stability of the oil was poor. The induction period by Rancimat test at 100,°C was 5.2,h. The radical-scavenging activity is similar to that of resveratrol [1,3-benzenediol 5-(1E -2-4-hydroxy-phenyl-ethyl)]. Although this product is used in the candy industry, it would be far more useful if raspberry oil of satisfactory quality could be extracted. This paper demonstrates that sifted lyophilized seeds can be used for the extraction of oils. This process allows for maximal usage of the byproducts, reduces losses and it increases the development of new products. [source] Novel polyketides synthesized with a higher plant stilbene synthaseFEBS JOURNAL, Issue 13 2001Hiroyuki Morita The physiological function of the stilbene synthase (STS) from groundnut (Arachis hypogaea) is the formation of resveratrol. The enzyme uses 4-coumaroyl-CoA, performs three condensations with malonyl-CoA, and folds the resulting tetraketide into a new aromatic ring system. We investigated the capacity for building novel and unusual polyketides from alternative substrates. Three types of products were obtained: (a) complete reaction (stilbene-type), (b) three condensations without formation of an aromatic ring (CTAL-type pyrone derailment), and (c) two condensations (BNY-type pyrone derailment). All product types were obtained from 4-fluorocinnamoyl-CoA and analogs in which the coumaroyl moiety was replaced by furan or thiophene. Only type (b) and (c) products were synthesized from other 4-substituted 4-coumaroyl-CoA analogs (-Cl, -Br, -OCH3). Benzoyl-CoA, phenylacetyl-CoA, and medium chain aliphatic CoA esters were poor substrates, and the majority of the products were of type (c). The results show that minor modifications can be used to direct the enzyme reaction to form a variety of different and new products. Manipulation of the biosynthesis of polyketides by synthetic analogs could lead to the development of a chemical library of pharmaceutically interesting novel polyketides. [source] Beneficial lactobacilli in food and feed: long-term use, biodiversity and proposals for specific and realistic safety assessmentsFEMS MICROBIOLOGY REVIEWS, Issue 4 2006Marion Bernardeau Abstract Lactobacilli have played a crucial role in the production of fermented products for millennia. Their probiotic effects have recently been studied and used in new products. Isolated cases of lactobacillemia have been reported in at-risk populations, but lactobacilli present an essentially negligible biological risk. We analyzed the current European guidelines for safety assessment in food/feed and conclude that they are not relevant for the Lactobacillus genus. We propose new specific guidelines, beginning by granting a ,long-standing presumption of safety' status to Lactobacillus genus based on its long history of safe use. Then, based on the available body of knowledge and intended use, only such tests as are useful will be necessary before attributing ,qualified presumption of safety' status. [source] The effect of accelerated ageing of building wiresFIRE AND MATERIALS, Issue 5 2007Viktor Emanuelsson Abstract The fire performance of two electric cables (building wires) designed for indoor use has been tested, both as new products and after accelerated thermooxidative ageing. The cables were aged for a maximum time of 16.5 weeks at 80°C. The cables are commercially available, and were constructed using a PVC material in one case and a non-halogenated polyolefin-based material, called Casico, in the other. The effects of ageing on the fire performance of the cables, and the chemical changes that have caused the observed fire behaviour, have been investigated and are discussed. Special attention is paid to the behaviour of the plasticizers that are used in the PVC cable, and how the fire behaviour is affected by the loss of plasticizers from the cable and by the migration of plasticizers between the parts of the cable (insulation, bedding and sheathing).

[source] Synthesis of New Resorcinarenes Under Alkaline ConditionsHELVETICA CHIMICA ACTA, Issue 10 2005Jean-Marc Bourgeois The preparation of functionalized resorcinarenes is described. Thus, 2-nitroresorcinol (=,2-nitrobenzene-1,2-diol), 2-acetylresorcinol (=,1-(2,6-dihydroxyphenyl)ethanone), and 2,6-dihydroxybenzoic acid were treated with formaldehyde in alkaline medium to give the corresponding resorcinarenes 1,3 (Scheme,1). This method is also applicable for resorcinol (=,benzene-1,3-diol) itself, but the yields are poorer. In this case, the molecule formed is the simplest resorcinarene 4 on which a number of substituents can be inserted between the two OH groups. Thus, bromation of 4 yields 5 (Scheme,2). Some properties and conformations of these new products are discussed, and the X-ray crystal structures of the nitro and bromo compounds 1 and 5, respectively, are presented. [source] Chemistry of phosphorus ylides 21 new route for the synthesis of azetidinones.HETEROATOM CHEMISTRY, Issue 6 2005Reaction of phosphonium ylides with benzil-, o -naphthoquinone-, triketonemonoanils Active vinylidenetriphenylphosphoranes are nucleophilic reagents which can be con- sidered as versatile synthons for the synthesis of new heterocycles. The active phosphacumulene ylides, namely N -phenylimino- 2a, 2-oxo- 2b or 2-thioxo-vinylidenetriphenylphosphoranes (2c), react with benzil- (1a,b), o -naphthoquinone- (8), or triketone-monoanils (11), to give the corresponding phenylimino- (3a, d, 9a, 12a), oxo- (3b, e, 9b, 12b), or thioxoazetidinones (3c, f, 9c, 12c), respectively, which constitute an important class of organic compounds with medicinal and biological importance. On the other hand, quinone monoanils 1a, 8, 11 can be converted by reaction with the stabilized alkylidenephosphoranes (5a,d), namely acetylmethylene- 5a, methoxycarbonylmethylene- 5b, ethoxycarbonylmethylene- 5c, and benzoylmethylene-triphenylphosphorane 5d, into the phosphoranylidenes (7a,d, 10a,d, 13a,d). No reaction was observed between iminophosphorane (14) and the monoanil (11). The structures of the new products were assigned according to consistent analytical and spectroscopic data. © 2005 Wiley Periodicals, Inc.

The sample included 23 establishments with 630 women respondents. Questionnaires, walk-through surveys of the industries, and interviews were done. The workplace factors included the content of the job, the nature of tasks, job autonomy, hazard exposure, and management and supervisory styles. Chi-square analysis showed that there were interactions among the organizational factors (P = 0.05 and 0.10). These factors included the need for better quality and new products; tasks requiring intense concentration; exposure to radiation, chemical, noise, and vapor hazards; standing for prolonged periods of time; and highly monitored, repetitious work. Workers experienced job stress (P = .05) when they were subjected to low job autonomy, poor work quality, close monitoring, and hazardous work pressure. © 2005 Wiley Periodicals, Inc.

Hall Abstract A suite of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow products at various spatial and temporal resolutions from the Terra satellite has been available since February 2000. Standard products include daily and 8-day composite 500 m resolution swath and tile products (which include fractional snow cover (FSC) and snow albedo), and 0·05° resolution products on a climate-modelling grid (CMG) (which also include FSC). These snow products (from Collection 4 (C4) reprocessing) are mature and most have been validated to varying degrees and are available to order through the National Snow and Ice Data Center. The overall absolute accuracy of the well-studied 500 m resolution swath (MOD10_L2) and daily tile (MOD10A1) products is ,93%, but varies by land-cover type and snow condition. The most frequent errors are due to snow/cloud discrimination problems, however, improvements in the MODIS cloud mask, an input product, have occurred in ,Collection 5' reprocessing. Detection of very thin snow (<1 cm thick) can also be problematic. Validation of MOD10_L2 and MOD10A1 applies to all higher-level products because all the higher-level products are all created from these products. The composited products may have larger errors due, in part, to errors propagated from daily products. Recently, new products have been developed. A fractional snow cover algorithm for the 500 m resolution products was developed, and is part of the C5 daily swath and tile products; a monthly CMG snow product at 0·05° resolution and a daily 0·25° resolution CMG snow product are also now available. Similar, but not identical products are also produced from the MODIS on the Aqua satellite, launched in May 2002, but the accuracy of those products has not yet been assessed in detail.

[source] Developing a dynamic project learning and cross-project learning capability: synthesizing two perspectivesINFORMATION SYSTEMS JOURNAL, Issue 6 2008Sue Newell Abstract Driven by the complexity of new products and services, project work has become increasingly common in all types of organizations. However, research on project learning suggests that often project teams do not meet their stated objectives and, moreover, there is limited organizational learning from the experiences of project work. We use the dynamic capabilities framework to argue that building a dynamic project learning capability is useful for organizations that make extensive use of projects. We use both survey and interview data to discuss the key ways in which such a dynamic capability can be built. Our survey data demonstrate the importance of documenting project learning, but our interview data show that teams are often remiss at documenting their learning. The results from the two different approaches are synthesized using Boland & Tenkasi's notions of perspective-making and perspective-taking. Importantly, combining the results from the two sets of data suggests that organizations need to emphasize the benefits from project reviews and documentation and explore ways in which the documents produced can be made more useful as boundary objects to encourage the sharing of learning across projects. [source] Flexural Strength Evaluation of Nonconstant Thickness Ceramic Floorings by Means of the Finite-Element MethodINTERNATIONAL JOURNAL OF APPLIED CERAMIC TECHNOLOGY, Issue 2 2010Beatriz Defez The ceramic tile industry has become an extremely competitive sector. The entry of new Asian and South American manufacturers into the market is shifting the leadership in production and exports from the traditional clusters of Europe to China, Turkey, and Brazil. In this uncertain environment, enterprises should raise the quality and cut costs by means of new products and processes. Ceramic tiles lightened by carving of a deep back relief could give rise to a generation of new, efficient products. These tiles could be manufactured with fewer raw materials than the traditional ones, which may lead to saving of weight and energy. Additionally, a lighter final product improves working conditions on the shopfloor and at the building site. Nevertheless, lightened tiles are structurally different from traditional ones, and so is their mechanical behavior. Because tiles are constructive elements, it is necessary to know their response under typical loads and assure fulfillment of the valid standards. This paper aims at evaluating the flexural strength (R) of lightened ceramic floorings using solid three-dimensional modelling and the finite-element method, establishing a new formula for the application of the international standard ISO 10545 "Ceramic Tiles." In order to achieve this objective, one reference model and 48 different relief versions were designed, which underwent a simplified computational simulation of the bending test. In accordance with the Rankine criterion, the maximal stresses of each version were calculated, as much as their distribution. Next, we correlated the results defining a new parameter called "normalized thickness," defined as the thickness that a carved tile should have to behave as a traditional flooring under flexion. This parameter allowed the adjustment of the international standard ISO 10545 to this kind of a product, facilitating their certification and therefore their real introduction in the market. Finally, thanks to the collaboration of the company Keros Cerámica S. A., it was verified that the methodology used was appropriate. [source] Cross-cultural evaluation of factors driving intention to purchase new food products , Beijing, China and south-east EnglandINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 4 2007Anita Eves Abstract It has been reported that consumers in different countries have distinctive perceptions of, and attitudes to, products. This study investigated consumers' thoughts on new food products in south-east England (n = 222) and Beijing, China (n = 139), using a questionnaire-based largely on the Theory of Reasoned Action. Results indicated that consumers in both countries believe it is necessary for the food industry in their respective countries to introduce new food products and they would like to try new products. There appears to be great interest in new products among the Beijing Chinese, with most interest in new healthy food products. The influences on choices suggest that a marketing focus on quality, utility and health benefits would be most fruitful, as personal beliefs were more important in intention to purchase than the influence of other people. Results point away from the expected result that the Chinese, as a collectivist culture, would place more emphasis on others' opinions than their own beliefs. This may be linked to food not being an item of conspicuous consumption, or to a cultural shift among urban Chinese. [source] The effect of income growth on the mix of purchases between disposable goods and reusable goodsINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 3 2007John McCollough Abstract With each passing year consumers find more and more disposable goods for sale in the market place. Even goods that were considered to be reusable goods just a few years back are now disposable goods. As a result the American economy has been labelled a ,throwaway society'. This paper examines a main underlying cause for this trend by linking growth in consumer income with the purchases of disposable goods. More specifically, the model proposes that as incomes rise, consumers will purchase more of both reusable goods and disposable goods. However, as incomes rise, consumers will naturally substitute purchases away from reusable goods and into disposable goods. The shift towards disposable goods occurs because it becomes too costly for consumers to spend their time repairing and maintaining products. Their time is better spent in more productive endeavours. It is simply cheaper (in terms of opportunity cost of time) to dispose of old products and replace them with new products. [source] Probiotic fermented milks: Present and futureINTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 4 2009BORJA SÁNCHEZ Milk and dairy products have been part of human nutrition since ancient times, constituting an important part of a balanced diet. Fermented dairy products containing living micro-organisms have traditionally been used to restore gut health, being among the pioneers in functional foods. Such utilisation of live micro-organisms forms the basis of the probiotic concept, which constitutes a fast growing market for the development of new products. In this article, we review the current status of fermented milk as a vehicle for delivery of beneficial bacteria and look into future new directions and challenges. [source] New product development practices of urban regeneration units: a comparative international studyINTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 4 2004Roger Bennett The new product development (NPD) activities of 14 not-for-profit urban regeneration organisations in three cities (London, Copenhagen and Boston) were examined to establish the degree to which they reflected the best practices recommended by the academic NPD literature in the for-profit field. Executives in each organisation were questioned about the stages of the NPD process that they activated most intensively, relationships between marketing staff and technical urban development specialists, mechanisms for consulting end users of place products, methods for generating new ideas and the major problems they experienced. Parallels between the NPD behaviour of nonprofit urban regeneration organisations managing projects involving widespread change and that previously observed among for-profit organisations engaged in the development of radically new products were investigated. Copyright © 2004 Henry Stewart Publications [source] The Elusive Underpinnings of U.S. Venturesomeness (If Not Prosperity),JOURNAL OF APPLIED CORPORATE FINANCE, Issue 2 2009Amar Bhidé This article explores the question of how the U.S. economy has managed to maintain (or even increase) its lead over other nations in per capita income and the average productivity of its workforce. The answer provided in the author's recent book is that such productivity depends on the greater willingness and effectiveness of U.S. consumers and businesses in making use of innovations in products and business processes. But this begs the question: What accounts for the increase in the innovative capabilities or effectiveness of U.S. consumers and businesses, both over time and relative to that of their global counterparts? After starting with the conventional "supply-side" focus on low taxes, limited regulatory barriers, and strong property rights, the author goes on to shift the main emphasis to the following six "institutional" contributors to U.S. prosperity: ,Breadth of participation: the modern U.S. economy draws, to a greater extent than either its global competitors or the U.S. of a century ago, on the contributions of far more individuals both as developers and as users of new products. ,Organizational diversity and specialization: the evolution of new forms of organization in the U.S., from small venture capital-backed firms to huge public corporations with dispersed ownership, has enabled the system to use the contributions of many individuals more effectively. ,Changes in common beliefs and attitudes: greater receptiveness to technological change has accelerated the adoption of new products in all countries, but especially in the U.S. ,Increased pressure for growth: the "grow or die" imperative faced by U.S. businesses has encouraged them to look for help from new technologies. ,The professionalization of management and sales functions,a distinctively U.S. phenomenon whose beginnings can be traced to IBM in the 1920s,has improved the capacity of modern U.S. organizations to develop markets and use new products. ,The expansion of higher education, to a far greater extent in the U.S. than elsewhere, has increased the supply of individuals with habits and attitudes that improve their ability to develop and use innovations. [source] Realizing the Potential of Real Options: Does Theory Meet Practice?JOURNAL OF APPLIED CORPORATE FINANCE, Issue 2 2005Alexander Triantis The idea of viewing corporate investment opportunities as "real options" has been around for over 25 years. Real options concepts and techniques now routinely appear in academic research in finance and economics, and have begun to influence scholarly work in virtually every business discipline, including strategy, organizations, management science, operations management, information systems, accounting, and marketing. Real options concepts have also made considerable headway in practice. Corporate managers are more likely to recognize options in their strategic planning process, and have become more proactive in designing flexibility into projects and contracts, frequently using real options vocabulary in their discussions. Thanks in part to the spread of real options thinking, today's strategic planners are more likely than their predecessors to recognize the "option" value of actions like the following: , dividing up large projects into a number of stages; , investing in the acquisition or production of information; , introducing "modularity" in manufacturing and design; , developing competing prototypes for new products; and , investing in overseas markets. But if real options has clearly succeeded as a way of thinking, the application of real options valuation methods has been limited to companies in relatively few industries and has thus failed to live up to expectations created in the mid- to late-1990s. Increased corporate acceptance and implementations of real options valuation techniques will require several changes coming together. On the theory side, we need more realistic models that better reflect differences between financial and real options, simple heuristic methods that can be more easily implemented (but that have been carefully benchmarked against more precise models), and better guidance on implementation issues such as the estimation of discount rates for the "optionless" underlying projects. On the practitioner side, we need user-friendly real options software, more senior-level buy-in, more deliberate diffusion of real options knowledge throughout organizations, better alignment of managerial incentives with long-term shareholder value, and better-designed contracts to correct the misalignment of incentives across the value chain. If these challenges can be met, there will continue to be a steady if gradual diffusion of real options analysis throughout organizations over the next few decades, with real options eventually becoming not only a standard part of corporate strategic planning, but also the primary valuation tool for assessing the expected shareholder effect of large capital investment projects.

Peng Abstract Aims:, To isolate a biosurfactant-producing bacterium and find new products within its culture. Methods and Results:, A biosurfactant-producing bacterium identified as Rhodococcus erythropolis (3C-9 strain) was isolated from seaside soil. When n -hexadecane was supplied as the sole carbon source, two types of biosurfactants (free fatty acids and glycolipids) were detected in the supernatant of the bacterial culture by use of thin layer chromatography (TLC). Gas chromatography,mass spectrometry (GC,MS) analysis revealed that the former consisted of at least 12 free fatty acids of chain lengths from C9 to C22; and the latter contained 2 kinds of glycolipids (a glucolipid and a trehalose lipid), which were detected by use of TLC, as well as GC,MS. The hydrophobic moieties of both glycolipids consisted of seven types of straight-chain fatty acids of varying compositions, with chain lengths ranging from C10 to C18. It was also noted that biosurfactants of strain 3C-9 were produced in a manner that was growth-related and cannot be synthesized from water-soluble substrates. The effects to enhance the solubility of polycyclic aromatic hydrocarbons and the degradation rate of hexadecane were also tested. Conclusions:, The biosurfactants produced by strain 3C-9 of R. erythropolis included two kinds of glycolipids, as well as free fatty acids. These biosurfactants were notably different from those of previously reported Rhodococcus species, both in terms of their structure and chemical composition. Significance and Impact of the Study:, Strain 3C-9 of R. erythropolis is a competitive candidate for use in oil spill cleanup operations, or in new biosurfactant exploration. The findings in this report show that Rhodococcus is a natural reservoir of new biosurfactants. [source] Discrimination of dynamical system models for biological and chemical processesJOURNAL OF COMPUTATIONAL CHEMISTRY, Issue 8 2007Sönke Lorenz Abstract In technical chemistry, systems biology and biotechnology, the construction of predictive models has become an essential step in process design and product optimization. Accurate modelling of the reactions requires detailed knowledge about the processes involved. However, when concerned with the development of new products and production techniques for example, this knowledge often is not available due to the lack of experimental data. Thus, when one has to work with a selection of proposed models, the main tasks of early development is to discriminate these models. In this article, a new statistical approach to model discrimination is described that ranks models wrt. the probability with which they reproduce the given data. The article introduces the new approach, discusses its statistical background, presents numerical techniques for its implementation and illustrates the application to examples from biokinetics. © 2007 Wiley Periodicals, Inc. J Comput Chem, 2007 [source] Effects of superstitious beliefs on consumer novelty seeking and independent judgment making: Evidence from ChinaJOURNAL OF CONSUMER BEHAVIOUR, Issue 6 2008Monica D. Hernandez Cultural content has been examined in consumer adoption of new products, whereas the relationship between enduring cultural beliefs and adoption remains unexplored. In this study, proactive superstitious behaviors (e.g., carrying a lucky charm) and passive superstitious beliefs (e.g., belief in fate) were empirically tested as antecedents of consumer novelty seeking (CNS) and consumer independent judgment making (CIJM). The results suggest that proactive superstitious beliefs positively influence CNS, whereas passive beliefs negatively influence CNS. Only passive superstitious beliefs positively influence CIJM. Results also suggest that previous superstition scales are incomplete and fail to reflect contemporary thinking about superstitious beliefs. Copyright © 2008 John Wiley & Sons, Ltd. [source] Parental consumer learning or ,keeping up with the children'JOURNAL OF CONSUMER BEHAVIOUR, Issue 4 2007Karin M. Ekström Children are socialized as consumers earlier now than any other time in history. The rapidly changing pace of society especially with regards to technology, information processing, transportation, etc. makes it possible for them to experience purchasing and consumption at a much faster rate than that of their parents. Children may possess knowledge which their parents lack and they may share their experience and knowledge and in so doing influence their parents. It can result in parents learning about consumption from their children, something which has not been sufficiently acknowledged by previous research. The purpose of this paper is to further the understanding of how consumption patterns and knowledge are transferred from children to parents. In-depth interviews carried out with ,children' of age group 13,30 show that they contributed information prior to and during the purchase, but also afterwards by helping to instal or showing parents how to use a product. The adolescents and adult children had often introduced new products to their parents and made them aware of recent trends. Often they also seemed to deal more easily with new technology than their parents. Copyright © 2007 John Wiley & Sons, Ltd. [source] Extending the brand image on new products: the facilitative effect of happy mood statesJOURNAL OF CONSUMER BEHAVIOUR, Issue 1 2007Rainer Greifeneder Investigates the influence of mood and brand favorability on the evaluation of brand extensions. It is argued that affective states have an impact on the likelihood that the evaluation of a new product is based on the implications of the brand rather than on the implications of the features of the new product. Specifically, participants reported more positive evaluations of a new product when it was introduced by a positive rather than a negative brand , and this differential impact of category information was more pronounced for participants in a positive compared to a neutral or a negative mood.
