The effects of skirt lining properties on comfort and movement

This study was conducted to clarify the influences of the lining properties of skirts upon comfort and movement. The comfort of lining fabrics and real skirts with and without lining was rated by sensory tests on the basis of sensorial comfort on the skin and body movement. Actual body movements were investigated by motion analysis while the skirts were being worn. The results are described: (1) Comfort on the skin, movement and overall preference for the lining fabrics were evaluated by sensory testing, comparing skirts made with five kinds of lining fabrics. Conventional non‐stretch cupro lining was ranked first on the basis of smoothness and good feel to the skin. Two‐way stretch lining was also ranked highly in terms of ease of movement. We discuss how sensorial comfort on the skin and ease of movement related to overall preference for lining fabrics. (2) Sensory test of the actual skirts with and without lining clearly confirmed that lining played a role in improving comfort. (3) For a non‐stretch fabric skirt, conventional lining was ranked highly for good feel to the skin, and two‐way stretch lining was considered useful for ease of movement. There was no significant difference between the two lining fabrics in overall preference. (4) For a stretch fabric skirt, stretch lining is the most useful because it maintains easy extension of the outer fabric, thus allowing ease of body movement. (5) Motion analysis showed that a combination of knitted stretch skirts with stretch lining was the best for ease of movement. Comparing the sidelines and the hemline of the stretch fabric skirts demonstrated a better shape using lining.     

Multiple Criteria Assessment of Insulating Materials with a Group Decision Framework Incorporating Outranking Preference Model and Characteristic Class Profiles

We present a group decision making framework for evaluating sustainability of the insulating materials. We tested thirteen materials on a model that was applied to retrofit a traditional rural building through roof’s insulation. To evaluate the materials from the socio-economic and environmental viewpoints, we combined life cycle costing and assessment with an adaptive comfort evaluation. In this way, the performances of each coating material were measured in terms of an incurred reduction of costs and consumption of resources, maintenance of the cultural and historic significance of buildings, and a guaranteed indoor thermal comfort. The comprehensive assessment of the materials involved their assignment to one of the three preference-ordered sustainability classes. For this purpose, we used a multiple criteria decision analysis approach that accounted for preferences of a few tens of rural buildings’ owners. The proposed methodological framework incorporated an outranking-based preference model to compare the insulating materials with the characteristic class profiles while using the weights derived from the revised Simos procedure. The initial sorting recommendation for each material was validated against the outcomes of robustness analysis that combined the preferences of individual stakeholders either at the output or at the input level. The analysis revealed that the most favorable materials in terms of their overall sustainability were glass wool, hemp fibres, kenaf fibres, polystyrene foam, polyurethane, and rock wool.     

Older adults: clothing preferences for thermal comfort in cold weather

Escalating energy prices and widely publicized energy saving practices in the last decade have induced some older consumers to lower household temperatures during cold weather. Therefore, the effective manipulation of clothing warrants consideration in maintaining thermal body comfort. The purpose of this research was to determine the clothing preferences of elderly consumers indoors during cold weather. Four hundred and fifty questionnaires were administered at three locations. Results from the study revealed that comfort was the most significant factor in selecting warm clothing. Although the respondents had implemented the effective use of clothing to achieve thermal comfort, the use of supplemental heat, and control of thermostat setting for heat was more prevalent. Suggestions and recommendations are made for practitioners who would address the issues of clothing for thermal comfort and energy conservation.     

Exploring consumers' preferences with regard to department and specialist food stores

Consumers' lifestyle changes and striving towards better time management have resulted in the greater choice they are offered with regard to store formats. Therefore, this study was undertaken to identify the factors that influence consumers in their patronage of a particular store format and to categorize department and specialist food store consumers according to their preferences in store layout and product range in a South African context. A qualitative research approach was used and data were collected using semi‐structured interviews with open‐ended questions. Purposive sampling recruited participants shopping for food in a department store in Johannesburg. Forty semi‐structured interviews were conducted before data saturation was reached. Store‐related factors such as store location, appearance and hygiene, service quality, convenience of trading hours, and consistency in store layout predominantly influenced participants in their patronage of a specific store format. Furthermore, product‐related factors such as quality, price, product range and convenient packaging enhanced consumers' store preference. Department store consumers were orientated towards one‐stop shopping and time‐saving strategies, while specialist food consumers were focused on food shopping and the trading hours of the store. Although similarities in participants' preferences with regard to department and specialist food store were found, different preferences were found regarding the placement of specific items within the store. Participants had similar preferences regarding the product range of a food store. However, department store participants emphasized the provision of convenience food and non‐food items. The findings of this study are valuable in providing department and specialist food store retailers with guideline recommendations regarding store layout and product range in order to effectively respond to the needs and preferences of consumers within an emerging economy.     

Adapting training to meet the preferred learning styles of different generations

This article considers how training professionals can respond to differences in training preferences between generational groups. It adopts two methods. First, it surveys the existing research and finds generally that preferences for training approaches can differ between groups and specifically that younger employees are perceived to leverage technology more at work. Second, it uses a qualitative grounded theory approach to examine the perspectives of a sample of older and a sample of younger workers in the United States. It finds that both samples perceive a greater comfort level of younger employees in leveraging technology‐enabled training and that the older sample were more comfortable with on‐the‐job and mentorship development efforts than more formal approaches. The implication for practice is that training needs to be more innovative so that, for any particular training intervention, potential trainees have a degree of freedom of choice of learning style. Possible approaches are discussed.     

Consumer attitude toward US versus domestic apparel in Taiwan

This study investigates whether or not consumer attitudes toward domestic‐ vs. US‐made apparel differ among consumers in Taiwan. Variables to be examined include (1) apparel attributes; (2) self‐concept; and (3) demographics. The Fishbein attitude model was used to measure consumer attitudes. The mall‐intercept method was used to collect most data in four major cities of Taiwan. A total of 485 Taiwanese consumers completed and returned useable questionnaires. Results indicated that consumer attitudes toward Taiwan vs. US‐made apparel differed significantly among consumers in Taiwan. Consumers had an overall more positive attitude towards US‐made apparel compared with Taiwan‐made apparel with regards to care instruction label, colour, quality, apparel fibre content, fashionableness, attractiveness, brand name, and comfort apparel attributes. For self‐concept variables only modest/vain and thrifty/indulgent had a significant difference between consumers who preferred US‐ over Taiwan‐made apparel. Demographic factors of age, gender, education, residence area, travelled abroad and country‐of‐origin preference had a significant relationship with consumer attitudes toward apparel. This study is aimed at understanding Taiwanese consumers’ attitudes toward foreign‐made apparel. Overall, Taiwanese consumers preferred US‐made apparel; however, the apparel attribute of size range needed improvement to increase customers’ satisfaction.     

Multilateralisation of Preferences versus Reciprocity when FTAs are Underutilized

Most studies worldwide, and all on East Asia on the impact of free trade agreements (FTAs), have assumed full utilisation of preferences. The evidence suggests that this assumption is seriously in error, with the estimated uptake particularly low in East Asia. In this paper, we assume a more realistic utilisation rate in estimating impacts. We find that actual utilisation rates significantly diminish the benefits from preferential liberalisation, but in a non‐linear way. Reciprocity is an important motivation for pursuing FTAs over unilateral actions, such as multilateralisation of preferences. We isolate the impact of reciprocity, but find that the additional benefits also depend on utilisation rates. Furthermore, the potential for trade deflection combined with possible retaliatory actions could negatively affect members and non‐members. In the absence of Doha, unilateral multilateralism or non‐reciprocal multilateralisation of preferences is the practical route that is most likely to deliver the greatest benefits.     

Using Bids,Arguments and Preferences in Sensitive Multi-unit Assignments: A p-Equitable Process and a Course Allocation Case Study

Bonus distribution in enterprises or course allocation at universities are examples of sensitive multi-unit assignment problems, where a set of resources is to be allocated among a set of agents having multi-unit demands. Automatic processes exist, based on quantitative information, for example bids or preference ranking, or even on lotteries. In sensitive cases, however, decisions are taken by persons also using qualitative information. At present, no multi-unit assignment system supports both quantitative and qualitative information. In this paper, we propose MUAP-LIS, an interactive process for multi-assignment problems where, in addition to bids and preferences, agents can give arguments to motivate their choices. Bids are used to automatically make pre-assignments, qualitative arguments and preferences help decision makers break ties in a founded way. A group decision support system, based on Logical Information Systems, allows decision makers to handle bids, arguments and preferences in a unified interface. We say that a process is p-equitable for a property p if all agents satisfying p are treated equally. We formally demonstrate that MUAP-LIS is p-equitable for a number of properties on bids, arguments and preferences. It is also Pareto-efficient and Gale–Shapley-stable with respect to bids. A successful course allocation case study is reported. It spans over two university years. The decision makers were confident about the process and the resulting assignment. Furthermore, the students, even the ones who did not get all their wishes, found the process to be equitable.     

On the measurement of investment types: Heterogeneity in corporate tax elasticities

This paper contributes to debates about the appropriate characterisation of heterogeneous investment types and to what extent different investment motives affect the responsiveness to corporate taxation. In particular, we employ and refine a methodology to better evaluate the tax elasticity of investment types. Using a combination of both firm‐specific information and sector‐specific information from input–output tables, we discuss how to classify investment as non‐related, horizontal, vertical and complex types. First, we point out to what extent the resulting classification depends on assumptions made by the researcher. Second, we employ an ample set of classifications and find that non‐related investment reacts stronger to corporate taxation, whereas horizontal investment is less responsive, though, significant negative tax semi‐elasticities turn out for the subset of manufacturing industries. To address inherent characteristics of vertical and complex investment, we extend the methodology and find that, by and large, stronger business motives reduce the tax responsiveness of investment to a larger extent. Given the current debates about substantial corporate tax reforms, it is all the more important to recognise that corporate tax effects can vary fundamentally between countries, driven by country‐specific differences in their composition of industries and investment types.     

A METHOD FOR PRICING AMERICAN OPTIONS USING SEMI‐INFINITE LINEAR PROGRAMMING

We introduce a new approach for the numerical pricing of American options. The main idea is to choose a finite number of suitable excessive functions (randomly) and to find the smallest majorant of the gain function in the span of these functions. The resulting problem is a linear semi‐infinite programming problem, that can be solved using standard algorithms. This leads to good upper bounds for the original problem. For our algorithms no discretization of space and time and no simulation is necessary. Furthermore it is applicable even for high‐dimensional problems. The algorithm provides an approximation of the value not only for one starting point, but for the complete value function on the continuation set, so that the optimal exercise region and, for example, the Greeks can be calculated. We apply the algorithm to (one‐ and) multidimensional diffusions and show it to be fast and accurate.     

Argumentation-Based Qualitative Preference Modelling with Incomplete and Uncertain Information

This paper presents an argumentation-based framework for the modelling of, and automated reasoning about multi-attribute preferences of a qualitative nature. The framework presents preferences according to the lexicographic ordering that is well-understood by humans. Preferences are derived in part from knowledge. Knowledge, however, may be incomplete or uncertain. The main contribution of the paper is that it shows how to reason about preferences when only incomplete or uncertain information is available. We propose a strategy that allows reasoning with incomplete information and discuss a number of strategies to handle uncertain information. It is shown how to extend the basic framework for modelling preferences to incorporate these strategies.     

The fashion‐conscious behaviours of mature female consumers

Under‐appreciation of mature consumers as a numerous and comparatively wealthy market segment has resulted in not only lost revenues for business, but also lost consumption and service opportunities for the elderly. In response to expressed needs for more research into actual and desired consumption by older consumers, this study examined the apparel and shopping preferences of mature women in America. Independent living residents were surveyed concerning fashion consciousness, fashion information sources and shopping behaviours. Young and mature consumers’ reactions to female apparel ensembles were compared. Mature subjects purchased apparel for pleasure or need, but less for conformity. Decisions were influenced more by fit and comfort than by fashion, despite suggestions that dressing stylishly was important. New fashions were encountered via catalogue illustrations, social gatherings and window displays. Subjects high in fashion consciousness had greater financial and social involvement with fashion, greater chronological‐to‐cognitive age differences and larger clothing budgets. Young and mature consumers’ responses to apparel illustrations differed significantly. As the mature market expands, attention to age‐divergent definitions of fashion (such as those based upon admiration of comfort) will determine the success of apparel businesses. Assessment of cognitive age will facilitate identification of those mature consumers most predisposed toward fashion consumption.     

A comparison of alternative theoretical explanations of consumer food safety assessments

The technical approach assumes that risk assessments made by technical experts are relatively objective and value‐free evaluations of the probability of negative consequences arising from use of a technology. Risk communication strategies associated with the technical approach focus upon educating an uninformed public about ‘actual’ risk. When consumer perceptions do not agree with technical assessments, consumers are deemed to be uniformed, irrational and sometimes dangerous to public health programmes. The social process approach assumes that technical assessments and applications of technology are influenced by political, social and economic interests. Consumer perceptions arise from social interaction with family and friends and depend strongly upon trust in societal institutions. Risk communication strategy emphasizes the importance of two‐way communication that encourages well reasoned public discourse and trust in societal institutions. Findings from examining the cognitive, emotional, and social determinants of perceptions of food irradiation for 164 adults residing in the Mid‐western USA indicate that the technical and social process approaches are complementary, but most of the variance in acceptance and perceived risk was explained by variables associated with the social process approach.     

Consumer Concerns Relating to Food Labeling and Trust—Australian Governance Actors Respond

This study aims to report and critically analyze the responses of governance actors to a set of consumers' concerns relating to food labeling, and by doing so describe how these actors construct both consumer perspectives and the food policy environment in which they work. Fifteen food‐labeling governance actors in Australia and New Zealand were asked to view an online presentation of the findings from a previous study exploring consumer perspectives on food labeling and trust before completing a one‐hour, in‐depth, semi‐structured interview. Colebatch's social constructionist perspective on policy was adopted in the analysis. Participants used their own constructions of Australian food policy, the role of labeling and consumer trust as a means to minimize the consumer concerns. Inadequate critical engagement with the moral dimension of consumer concerns is a core driver of the inertia demonstrated in the Australian government's approach to addressing consumer concerns regarding food matters.     

Reduced‐fat foods: the shopper’s viewpoint

The inclusion of reduced‐fat foods in the daily diet affords consumers the potential to reduce overall dietary fat. Nevertheless, despite an increased range of these food products throughout the market, there has remained a lack of widespread consumer acceptance. The aim of the study was therefore to understand why consumers choose or reject reduced‐fat foods. Ninety consumers were interviewed by means of a qualitative approach within food retail outlets in the United Kingdom. Thematic content analysis indicated that uptake or rejection of these products is influenced by health concerns, ‘goodness of fit’ with individual dietary health strategies, the preferences of different household members, perceived sensory properties and scepticism towards these products. The results imply a need to explore and innovate ‘natural’ fat substitutes and to improve the sensory quality of reduced‐fat products. Further research is required to determine how these foods are used within the household and incorporated within the overall diet. Policy must seek to restore consumer trust in reduced‐fat food products and the food supply generally.     

Distance from core competences and new export survival: Evidence from multi‐product exporters

We study the determinants of the survival of new export products of multi‐product firms. We use micro‐level data from Chile to estimate linear fixed‐effects and non‐linear survival models to show that a measure of “distance” between a firm's new export and its previous export basket is a negative and significant determinant of the survival of the new export, especially during its first year. Our interpretation of this finding is that exports further away from firms’ core competences have lower chances of survival in exports since it is more difficult for firms to achieve competitiveness in them. Our results suggest that country‐level diversification, at least through existing firms, should be gradual.     

Density forecast comparisons for stock prices,obtained from high‐frequency returns and daily option prices

This paper presents the first comparison of the accuracy of density forecasts for stock prices. Six sets of forecasts are evaluated for DJIA stocks, across four forecast horizons. Two forecasts are risk‐neutral densities implied by the Black–Scholes and Heston models. The third set are historical lognormal densities with dispersion determined by forecasts of realized variances obtained from 5‐min returns. Three further sets are defined by transforming risk‐neutral and historical densities into real‐world densities. The most accurate method applies the risk transformation to the Black–Scholes densities. This method outperforms all others for 87% of the comparisons made using the likelihood criterion.
