Learning CAD at university through summaries of the rules of design intent

The ease with which 3D CAD models may be modified and reused are two key aspects that improve the design-intent variable and that can significantly shorten the development timelines of a product. A set of rules are gathered from various authors that take different 3D modelling strategies into account. These rules are then applied to CAD strategic-knowledge learning methodology and included in 3D CAD modelling exercises for students following the degree in mechanical engineering at the University of Burgos (Spain). The experiment was conducted in two groups with a total of 75 students. The design-intent rules were introduced in the different exercises that the teacher explained in both the theoretical and the practical classes. In addition, a summary of the different design rules in each of the practical exercises was explained in the practical classes in only one of the groups. The experimental results, reported in this paper, tested the influence of these summaries on overall improvements in 3D modelling and on the design-intent variable, which is subdivided into four sections: skeleton, structures, alterations and constraints. The use of the summaries of the design intent rules led to statistically significant improvements in 3D modelling in the experimental group, in comparison with the group of students to whom those summaries were not explained.     

NEW FORMS OF PROVIDER IN THE ENGLISH NATIONAL HEALTH SERVICE

ABSTRACT 1 : A wide ranging set of reforms is being introduced into the English National Health Service (NHS). They are designed to increase the market‐like behaviour of providers of care with a view to improving efficiency, quality and responsiveness of services. This paper is concerned with one aspect of those reforms: namely the policy to increase the diversity of types of providers of care to NHS patients. In this context, increasing diversity means that providers will not all be standard publicly owned NHS organizations. They can be publicly owned but autonomous, or independent (both in for‐profit and not for profit). The paper discusses the wide range of organizational forms available, analyzing their governance structures It then discusses the small amount of evidence currently available about the performance of diverse providers of health care.     

Comparison of Cramer–Rao lower bounds of variances for at least equal protection of respondents

In this paper, a new randomized response model is proposed, which is shown to have a Cramer–Rao lower bound of variance that is lower than the Cramer–Rao lower bound of variance suggested by Singh and Sedory at equal protection or greater protection of respondents. A new measure of protection of respondents in the setup of the efficient use of two decks of cards, because of Odumade and Singh, is also suggested. The developed Cramer–Rao lower bounds of variances are compared under different situations through exact numerical illustrations. Survey data to estimate the proportion of students who have sometimes driven a vehicle after drinking alcohol and feeling over the legal limit are collected by using the proposed randomization device and then analyzed. The proposed randomized response technique is also compared with a black box technique within the same survey. A method to determine minimum sample size in randomized response sampling based on a small pilot survey is also given.     

Organic as a Heuristic Cue: What Spanish Consumers Mean by Organic Foods

One of the strategies employed by companies to differentiate themselves from others, in the food market, has been to market organic products according to the assumption that environmental values are an important influence on people's behavior. However, studies of the behavior of organic food consumers show that there is some debate on this subject. Although some studies associate organic food consumption with motives and attitudes in which the environment plays a predominant role, a greater number conclude that the motives for consuming this type of food are basically egoistic (related to health, food safety, or the quality or flavor of the food). This can lead to problems in deciding the central thrust of the marketing strategy. The purpose of this paper is to analyze the meaning and interpretations placed on the term “organic,” and how they are integrated, as a way to explain consumption behavior. Qualitative research methods were adopted for this purpose. Four focus group sessions with different sociodemographic profiles, held in the cities of Madrid and Seville, in Spain, displayed two evident paradoxes, which could indicate that environmental motives are not important for consumers in this market. It is concluded that the term “organic” plays an important role as a heuristic cue to superiority, irrespective of the consumer's knowledge about the real features of organic food. Three alternative models are presented to explain consumer behavior. These results could be useful to food companies, largely in connection with positioning this type of product and with their communications policy.     

Road Travelers' Motivations and Loyalty: Train Versus Bus Services

ABSTRACT

Railroad and highway travel may differ not only in terms of their nature but also in terms of their appeal to travelers. Travelers may have different motivations to use either transportation mode in either inbound or outbound directions. Travelers may also demand different services or service traits of the provider in order to gain satisfaction in the short-term and/or become loyal customers in the long-term. This study uses a 2?×?2 design to compare train and a bus service between two cities 250 km apart in a country where these two means of transportation are equally essential. The study also compares the outbound and inbound routes in order to acknowledge additional differences in both the travelers' motivations and the customers' loyalty formation. The results show that travelers' motivations for choosing train or bus transportation differ based on whether they are leaving from or returning to the city that was the original point of departure. They also show that customers' long-term relationships with the provider significantly differ according to means of transportation and routes used. Characteristically, customers in the studied sample prefer train transport to leave and bus to return based on their idiosyncratic motivations of seeking value or money savings and their expectations of mutual loyalty. This research suggests practical consequences both for understanding travelers' motivations and customer loyalty formation and for managing policies regarding train and bus services competing for specific segments of travelers.     

Designing experiences strategically

Companies willing to enter into the experience economy have available procedures for experience design and evaluation but not for strategic decision-making on what experiences to incorporate into their offering. This study presents a procedure for identifying experiences and for assessing their customer value. The fieldwork consists of a logbook technique for experience identification and their subsequent strategic assessment considering people's perceptions of the influence each experience has in their quality-of-life, their interest in living each experience, and their previous knowledge of each experience. The paper focuses on experiences related to environmental design. In that setting, the procedure led to the identification of 13 different experiences. A clustering analysis identified six groups of experiences accordingly to the perception of 142 persons interviewed: experiences that have a ready market, experiences with a market to captivate, experiences with a potential market, experiences indifferent for a given market, experiences with lost clients and experiences that need a better adjustment to the market.     

CSR Disclosure Items Used as Fairness Heuristics in the Investment Decision

The growth in demand for corporate social responsibility (CSR) information raises the question of how various CSR disclosure items are used by investors, an important stakeholder group driven by instrumental, moral, and relational motives. Prior research examines the instrumental motive to maximize individual shareholder wealth and the moral motive to actualize personal stewardship interests. We contribute to the literature by examining investors’ relational motive to realize positive stakeholder relationships within and between organizations and communities. The relational motive arises when investors look at a company’s treatment of other stakeholder groups as a heuristic to form a perception of how fairly they will also be treated by that company in the future, and thus invest in the company they perceive as fair. Fair treatment in the future matters to the investor who purchases stock from the company or via the capital markets in exchange for becoming a shareholder and thus a residual claimant of the company. As such, the investor expects future cash flows from holding and/or reselling the stock and expects to be treated fairly by the company in the future. We propose that investors, use as a fairness heuristic, CSR disclosure items—CSR investment level or CSR assurance—that represent the company’s commitment to its stakeholders, and that the resulting fairness perception affects the extent to which the CSR disclosure items influence their investment decision. Using responses from 113 investors in an online experiment, we find that fairness perceptions are higher when CSR investment is above (versus below) the industry average, and that fairness perceptions partially mediate the impact of the CSR investment level on investment amount allocations. We do not find that the presence (versus absence) of CSR assurance is used by investors as a fairness heuristic. Our results are robust to controlling for preferences for financial performance and hence investors’ instrumental motive, and to controlling for individual environmental attitudes, and hence investors’ moral motive. Implications for future research and public policy are discussed.     

The Effects of Current Income Attributes on Nonprofessional Investors’ Say-on-Pay Judgments: Does Fairness Still Matter?

The say-on-pay (SOP) regulation in the Dodd-Frank Act (Public L. no. 111–203, H.R. 4173 2010) requires publicly-traded U.S. firms to hold a nonbinding, advisory shareholder vote on executive compensation. Advocates claim that SOP voting gives shareholders a mechanism to hold managers and boards more accountable. Critics contend that SOP votes may simplistically reflect shareholders’ reactions to the overall value of CEO compensation or the firm’s net income. However, based on prior research, we contend that market participants’ SOP votes are likely to consider current income attributes. For example, the market punishes firms that do not meet or beat benchmarks such as analyst earnings expectations, and that shareholders scrutinize the quality of the income sources of firms that consistently meet/beat analyst expectations. We thus expect that more shareholders will provide ‘agree’ SOP votes for a firm that consistently meets/beats analyst forecasts and does so when net income does not include (rather than includes) nonrecurring gains. Further, we consider whether perceptions about the fairness of CEO compensation play a mediating role in the relationship between the interaction of these two current income attributes and SOP votes. Results from an experiment using evening MBA students as participants indicates that the two current income attributes significantly interact with respect to the percentage of agree SOP votes, and that compensation fairness perceptions fully mediate this relationship. Further, the mediating effect of compensation fairness perceptions is robust to including CEO-level and other determinants found in prior research. We conclude with a discussion of our findings and their implications for public policy and research.
