Comparative study of industrial design undergraduate education in China and USA

Industrial design (ID) undergraduate education in China is seen as a new rapidly growing discipline over the past 40 years. China’s ID education is not well known in the West due to several barriers: language, the Great Firewall of China which blocks out most of the Western websites and a 12-h time difference. All Chinese ID curriculum and program information are available in Mandarin. The Ministry of Education administers all Chinese design education as well as ID scholarships and faculty exchange grants and its website and documents require translation. The Great Firewall of China blocks 90% of Western websites including Google making it difficult for Western Scholars to access accurate information about the size and shape of the Chinese ID education landscape. China has a historical relationship between the ID schools in China and the United States. Chinese students are studying or alumni of every American ID program. China and USA share similar program types, dual-track admissions for art and design streams, and academic calendars. In this paper, a model was developed to clarify the features of ID undergraduate education in China and USA, and a survey of eight ID schools was processed. Four aspects were comparatively discussed: (1) types of ID education, (2) ranking, evaluation, and certification of ID schools and programs, (3) curriculum, credits, course features, and yearly schedules of schools, (4) influences coming from the culture and globalization process. Based on the analysis, the similarities and differences in ID undergraduate education between the two countries are discussed. Results show the dual-track modes in China and USA are different. It is mainly reflected in the management and enrollment, curriculum organization, and cultural environment. Implications for the localization, openness, and globalization to ID education are finally discussed together with several directions for future development. The findings are valuable to USA and Chinese ID departments and faculty, researchers, staff and visiting scholars. It is also useful for university administrative units such as registrars, admissions, international offices and exchanges to understand each other.

     

National minorities and their representation in social surveys: which practices make a difference?

This paper presents a systematic study of survey mechanisms that produce or reduce minority bias in social surveys. It extends the work of Lipps et al. (2011) who have demonstrated that, in the Swiss context, the more an ethno-national minority community differs, socio-culturally and socio-economically, from the national majority, the less it is likely to be represented in its proper proportion in the major national surveys. Minority bias furthermore has a vertical dimension: socio-economic bias against individuals from the most deprived backgrounds becomes extreme within ethno-national minority communities. Using data from the Swiss Labour Force Survey, the Swiss Household Panel, and the Swiss sample of the European Social Survey, in the present work we empirically assess the impact of three types of survey practices on minority bias: (1) strategies to increase overall response rates of the whole population indiscriminately from its minority status, (2) the use of pre- and post-stratification measures that take into account the overall share of foreigners in the national population, and (3) the conduct of interviews in a wider range of languages, in order to facilitate survey response among certain (linguistic) minorities. Our findings show that efforts to increase overall response rates can, paradoxically, create even more minority bias. On the other hand, they suggest that a combination of stratified sampling and a wider range of survey languages can have a positive effect in reducing survey bias, both between and within national categories. We conclude that measures that take into account and adapt to the social and cultural heterogeneity of surveyed populations do make a difference, whereas additional efforts that only replicate existing routine practices can be counter-productive.     

Estimating Cash Usage: The Impact of Survey Design on Research Outcomes

We employ a unique dataset of transaction records to analyse the impact of survey set-up on consumers’ payments registration behaviour. Survey data are used for econometric analyses and validated against other payments data. The results reveal that the length of the registration period influences consumers’ registration of payments. Measurement errors are minimised when consumers use a self-reported transaction diary for one single day. Around 40 % of the transactions registered in a one-day survey are missed out in a one-week survey. Apart from payments research, the results are, among others, also relevant for household expenditure and marketing research.     

Collateralized Social Relations: The Social in Economic Calculation

Traditionally, economists have viewed social relations as "friction" or "impediments" to exchange and have excluded social relations from their analyses by assuming autonomous actors. Recently, however, a number of scholars—economists, sociologists, anthropologists, and other social scientists—have begun to discuss the numerous ways in which social arrangements both prompt and channel economic activity. Rational choice theory, social capital and network analysis, and agency and game theory, are among those approaches that consider the effects of social relations on economic action. In this paper we extend that discussion by arguing that social relations can function as "collateral" or assurance that an economic transaction will proceed as agreed by the parties involved. We review recent microeconomic theories and conjecture how they might be developed following this observation, which is derived from sociological and anthropological studies of economic action and organization.     

Optimal route decision with a geometric ground-airborne hybrid model under weather uncertainty

Adverse weather is the dominant cause of delays in the National Airspace System (NAS). Since the future weather condition is only predictable with a certain degree of accuracy, managing traffic in the weather-affected airspace is a challenging task. In this paper, we propose a geometric model to generate an optimal combination of ground delay and route choice to hedge against weather risk. The geometric recourse model (GRM) is a strategic Probabilistic Air Traffic Management (PATM) model that generates optimal route choice, incorporating route hedging and en-route recourse to respond to weather change: hedged routes are routes other than the nominal or the detour one, and recourse occurs when the weather restricted airspace becomes flyable and aircraft are re-routed to fly direct to the destination. Among several variations of the GRM, we focus on the hybrid Dual Recourse Model (DRM), which allows ground delay as well as route hedging and recourses, when the weather clearance time follows a uniform distribution. The formulation of the hybrid DRM involves two decision variables - ground delay and route choice - and four parameters: storm location, storm size, maximum storm duration time, and ground-airborne cost ratio. The objective function has two components: expected total ground delay cost and expected total airborne cost. We propose a solution algorithm that guarantees to find the global optimum of the hybrid-DRM. Based on the numerical analysis, we find that ground-holding is effective only when combined with the nominal route. Otherwise, it is optimal to fly on the route determined by the DRM without ground delay. We also find the formula of the threshold ground-airborne cost ratio, which we call the Critical Cost Ratio (CCR), that determines the efficacy of ground delay: the higher the CCR, the more effective the strategies involving ground delay. We conclude that both ground delay and route hedging should be considered together to produce the best ATM decisions.     

Institutional industry herding

We examine whether institutional investors follow each other into and out of the same industries. Our empirical results reveal strong evidence of institutional industry herding. The cross-sectional correlation between the fraction of institutional traders buying an industry this quarter and the fraction buying last quarter, for example, averages 40%. Additional tests suggest that correlated signals primarily drive institutional industry herding. Our results also provide empirical support for “style investing” models.     

The Effect of Accounting Restatements on Earnings Revisions and the Estimated Cost of Capital

This paper examines the effect of accounting restatements on a firm's cost of equity capital. We show that, on average, accounting restatements lead to both decreases in expected future earnings and increases in the firm's cost of equity capital. Depending on the model used, relative percentage increases in the cost of equity capital average between 7 and 19% in the month immediately following a restatement. The relative increase in the cost of capital dissipates as time passes and after controlling for analyst forecast biases, but continues to average between 6 and 15% in the most conservative setting. We also show that restatements initiated by auditors are associated with the largest increase in the cost of capital, and that firms with greater leverage experience greater increases in their cost of capital. Overall, our evidence is consistent with accounting restatements lowering the perceived earnings quality of the firm and increasing investors' required rates of return.     

Hospital costs associated with thyroidectomy performed with a Harmonic device compared to conventional techniques: a systematic review and meta-analysis

Objectives: Harmonic devices have become a world-wide standard for dissection and hemostasis in thyroidectomy. Numerous systematic reviews have reported superior operating times, blood loss, post-operative pain, length of stay, and overall safety outcomes. What has not been extensively evaluated in a robust manner is their economic impact. The purpose of this study is to evaluate the hospital costs associated with open thyroidectomy using Harmonic devices compared with conventional techniques for hemostasis. Methods: A systematic review of Medline, Scopus, and CENTRAL was performed from January 1, 2000 to May 23, 2014 without language restrictions for randomized clinical trials comparing Harmonic surgical devices to conventional methods in thyroidectomy. The main outcome measure was total reported costs. Costs were pooled using the ratio of means and a random effects model. Sensitivity analyses assessed whether differences in patient and trial characteristics, healthcare setting, or choice of statistical model affected outcomes. Results: Seven studies met the inclusion criteria. A total of 476 participants had procedures performed with Harmonic devices and 478 with conventional monopolar electrosurgery and clamp, cut and tie techniques. Compared with conventional techniques, Harmonic devices reduced total reported costs by 10% (p?=?0.007), resulting in a $229?US dollars (USD) absolute reduction from mean baseline costs. Results remained relatively robust to additional sensitivity analyses. Conclusions: This systematic review and meta-analysis demonstrates that the Harmonic family of surgical devices is associated with a reduction in total reported costs in thyroidectomy compared with conventional techniques. A large portion of the overall savings derives from a reduction in operative costs.
