Low cost fabrication of a superhydrophobic V-grooved polymer surface.
Hurst, Steven M,Farshchian, Bahador,Brumfield, Lance,Ok, Jeong Tae,Choi, Junseo,Kim, Jinsoo,Parkl, Sunggook American Scientific Publishers 2013 Journal of Nanoscience and Nanotechnology Vol.13 No.3
<P>Engineering of polymer surfaces to control their wetting properties has shown a wide range of potential applications. In this paper we show low cost fabrication of a superhydrophobic polymer surface via a hierarchical combination of hot embossing, O2 reactive ion etching (RIE) and deposition of a hydrophobic silane. The hot embossing and O2 RIE were used to produce respective micro and nanoscale surface roughness which is a requirement for obtaining superhydrophobic surfaces, while the deposition of a hydrophobic silane modified surface chemistry. In order to increase the water/air interface in the Cassie-Baxter composite wetting model, a brass mold with microscale V-grooves was used for hot embossing. Images of droplets in both static water contact angles and dynamic impact tests with the surface clearly show that the wetting state follows the Cassie-Baxter wetting model. The results of this study indicate that our design of the dual level surface roughness and the fabrication process allow for low cost and easy production of a highly superhydrophobic surface.</P>

Background: Type 2 diabetes mellitus (T2DM) is a global pandemic and its prevalence is rapidly increasing in developing countries, including Thailand. The most common comorbidity of T2DM is hypertension. T2DM with a hypertension comorbidity is likely to exacerbate the development of, or more severe microvascular complications. This study aims to determine the association between the hypertension comorbidity and microvascular complication among T2DM patients in Thailand. Methods: The present study is a nationwide, multicenter, cross-sectional survey of T2DM outpatients across Thailand. Binary logistic mixed effect regression was used to investigate the effect of hypertension and other risk factors on the presence of microvascular complications. Imputation was used to investigate potential bias introduced by missing values. Results: Of the 55,797 T2DM patients included in our sample, 55.35% were hypertensive. Prevalence of microvascular complication diagnosis in the last 12 months was higher in T2DM patients with hypertension than those without hypertension (12.12% vs. 9.80%, respectively). Patient with a hypertension comorbidity had 1.32 time the odds of developing microvascular complication (adjusted odds ratio [OR], 1.32; 95% confidence interval [CI], 1.20 to 1.46; P<0.001). Older age, longer diabetes duration had 1.07 and 1.21 times the odds of developing microvascular complication, per 10 years (age) and 5 years (duration), respectively (ORage, 1.07; 95% CI, 1.03 to 1.12; P<0.001; and ORduration, 1.12; 95% CI, 1.07 to 1.16; P<0.001; respectively). Minimal bias was introduced by missing values, and did not influence to the magnitude of effect of hypertension on the presence microvascular complication. Conclusion: Hypertension comorbidity is highly associated with microvascular complication among T2DM patients. Patients with T2DM and physicians should pay attention to blood pressure control.

Conversion Intentions of Fashion Marketing Interns
Jessica L. Hurst,Linda S. Niehm,Sunhee Park 한국마케팅과학회 2010 Journal of Global Fashion Marketing Vol.1 No.2
Fashion marketing/retailing is a major employment sector and driver of economic activity on a global level. Michael Porter’s (1985) popular value chain perspective demonstrates the importance of marketing and retail sales among a set of primary value creating activities for firms of all types. The value chain perspective also illuminates the importance of human resources as a support activity necessary to create value and assure the success of the firm. This research addresses the potential value for fashion marketing/retailing firms that may be achieved through employee development practices such as offering pre-professional internships. We focus on college students’ perceptions of fashion marketing/retail-related internships d the factors that cause interns to accept a job offer upon internship completion. This study specifically examines relationships between internship experiential components of psychological contracts, supervisory support, affective organizational commitment and job satisfaction. Unlike other industry sectors, retailing is not limited to a specific region and thus provides job opportunities for fashion and retail degree graduates on a nearly global scale. (“Future Employment in Retail…” 2009) In fashion maketing/retailing, there continues to be a high level of job attractiveness on the part of students, yet an observed disconnect exists between student career goals, expectations, and resulting job satisfaction. In reality, there is a much larger scope of opportunity in fashion related retail than just positions on the sales floor. Students must therefore obtain exposure through their courses and other types of learning, such as internships and practicum experiences, to realize the diversity of job opportunities in fashion marketing/ retailing including sales, buying, logistics, product development, merchandising, finance, human resources, and more (“Get Tailor–Made Training….” 2006). Additionally, many positions in fashion retailing are increasingly becoming cross-functional, suggesting that students need to have a complete understanding of the contemporary marketplace and be exposed to a variety of job settings and experiences (“Retail Rewards” 2006). This research is framed by psychological contract theory (Rousseau 2000) and organizational commitment theory (Van Maanen 1975). Psychological contract theory combines employer-based beliefs (i.e. employer obligations) with individual-based beliefs (i.e. employee obligations) regarding the nature of an agreement and the relationship between that individual and his/her employer. Combining perceptions of employer-based obligations with employee obligations allows for an ideal assessment of specific idiosyncratic information that is meaningful and unique to each individual, as well as the firm (Robinson, Kraatz and Rousseau 1994). Organizational socialization theory explains how newcomers learn the culture and values of new job settings (Van Maanen 1975). The theory also explicates how newcomers must develop the necessary work skills and adjust to the work environment (Feldman 1976). An on-line, self-administered, survey questionnaire was used to collect data in this study. The final sample consisted of 229 college students who completed a fashion merchandising, fashion marketing, fashion design, or retail-related internship. Following verification of the reliability of the measurement items, path analysis was conducted. A proposed path model of internship conversion was estimated using AMOS 5.0 statistical software. A modified final model showed that six paths were statistically significant and had positive path coefficients, as hypothesized. Hypothesis H1a stated that interns’ supervisory support will have a positive effect on psychological contract expectations of employer obligations.

Gamma Spectrum from Neutron Capture on Tungsten Isotopes
A. M. Hurst,N. C. Summers,B. W. Sleaford,R. B. Firestone,T. Belgya,Z. S. Revay 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
An evaluation of thermal neutron capture on the stable tungsten isotopes is presented, with preliminary results for the compound systems ^(183,184,185,187)W. The evaluation procedure compares the γ-ray cross-section data collected at the Budapest reactor, with Monte Carlo simulations of γ-ray emission following the thermal neutron-capture process. The statistical-decay code DICEBOX was used for the Monte Carlo simulations. The evaluation yields new γ-rays in ^(185)W and the confirmation of spins in ^(187)W, raising the number of levels below which the level schemes are considered complete, thus increasing the number of levels that can be used in neutron data libraries.

Jonathan Kinkel,William Hurst 동아시아연구원 2011 Journal of East Asian Studies Vol.11 No.3
Since the upheaval of the Cultural Revolution decade (1966–1976), post-Mao China has witnessed a sustained period of unprecedented legal reform. Criminal prosecutions and citizen lawsuits against the government, because they pit individual litigants against the authoritarian Chinese state, are two politically significant areas of law. We examine and critically assess the sociolegal scholarship on criminal and dministrative legal reform as it has developed over the past few decades, with special attention to shifts in the conventional wisdom regarding legal reform and political liberalism in China and elsewhere. Additionally, we offer both theoretical and empirical suggestions for enhancing the explanatory power of sociolegal research in China.

The Importance of Brand and Retailer Associations in Evaluating a Product Category Extension
Eom, Hyo Jin,Hunt-Hurst, Patricia,Lu, Zhenqiu (Laura) The Costume Culture Association 2018 Fashion, industry and education Vol.16 No.2
This study investigates the importance of brand and retailer associations when consumers evaluate a product category extension in the context of brand and retailer collaborations. Although brand extensions are considered to reduce costs for introducing a new product category, limited study has focused on the role of brand and retailer associations in the context of brand and retailer collaborations. Using a total of 440 participants, a hypothesized model was tested using a structural equation modeling (SEM). The results show that brand and retailer associations influence the perceived fit between a brand and a retailer. In addition, the image fit and quality fit are significantly related to brand and retailer attitudes as well as brand extension evaluation. Since consumers may use their associations with brands or retailers when they perceive product differentiation, market position, and brand extensions, the role of brand or retailer associations is important to marketers, retailers, and consumers. Given the importance of brand and retailer collaborations as a brand positioning strategy in the global branding and retail setting, the findings of this study contribute to brand and retail management by providing empirical evidence on how consumers perceive new products from extended brands in the marketplace when a brand collaborates with a retailer.
