THE INTERPLAY BETWEEN ROBOT DESIGN, CUSTOMER PERCEPTIONS AND SERVICE OUTCOMES: A FSQCA PERSPECTIVE

Hector Gonzalez-Jimenez,Yang Sun 글로벌지식마케팅경영학회 2020 Global Marketing Conference Vol.2020 No.11

Prior social robotics research has shown that robot design influences if people perceive a robot as friendly, trustworthy, or safe (Castro-Gonzalez et al., 2016; Rosenthal-Von Der P?tten & Kr?mer, 2014). Meanwhile, recent conceptual work has suggested that social robots will increasingly be used in the front line of service encounters (Gonzalez-Jimenez, 2018; Van doorn et al., 2017). According to The International Journal of Social Robotics social robots are robots that can communicate and interact with humans, among themselves, and with the environment, within the cultural and social structure assigned to its role. Real examples of the inclusion of these robots in retail settings already exist. For instance, some retailers use Softbank´s robot Pepper to greet and inform customers. Social robots such as Pepper can use their sensors and cameras to interpret customer reactions and adapt accordingly. Moreover, the robot can even make product recommendations based on the assessed customer´s mood, age, gender and, if available, purchase history (McKenna, 2018). Not surprisingly, there is a vast market potential associated with these robots, which is expected to grow to 87 billion by 2025 (BCG, 2017).

THE ROLE OF MATERIALISM AND SOCIAL COMPARISON IN CLOTHING CHOICES

Hector Gonzalez-Jimenez,Sujin Song 글로벌지식마케팅경영학회 2017 Global Fashion Management Conference Vol.2017 No.07

Individuals use material possessions such as clothes as a means to express their individual predispositions, values and position in their social environment (Kaiser et al., 2001). Evidence indicates that various individual differences such as hormone levels, body image perception and a cosmopolitan orientation influence clothing choices (Eisenbruch et al., 2015, Frith and Gleeson, 2004, Gonzalez-Jimenez, 2016). Moreover, body satisfaction, body mass index and trait self-objectification determine if individuals choose clothes for specific purposes such as fashion, comfort or camouflage (Tiggemann and Andrew, 2012). However, while these studies have made an important step towards understanding the influence of individual characteristics on clothing choices, there is a lack of studies that investigate the role of individuals’ materialist tendencies and propensity to engage in social comparison. We extend prior research on clothing choices by examining the associations between individuals’ materialist tendencies and social comparison propensity with sought clothing functions (i.e., fashion, comfort, etc.). Findings show that materialist individuals seek clothing for specific functions such as fashion, individuality and assurance, while avoiding clothes designed for comfort. Individuals’ propensity to engage in social comparison is linked with choosing clothes for fashion, individuality and assurance, but not for camouflage and comfort. Our study confirms that materialism and social comparison drive individuals to seek very specific clothing functions. Specifically, findings suggest that individuals use specific clothing types as a medium to establish their position in a social environment and to express their materialistic tendencies. Gender influences the tested relationships.

Application of solar advanced oxidation processes to the degradation of the antibiotic sulfamethoxazole

Gonzalez, O.,Sans, C.,Esplugas, S.,Malato, S. Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.7

This work deals with the treatment of highly concentrated sulfamethoxazole (SMX) solutions by some advanced oxidation processes (AOPs) that have not been studied until now. The antibiotic has been subjected to oxidation by photolysis, UV/$H_2O_2$ and photo-Fenton using both artificial light and sunlight as radiation sources depending on the installation scale. SMX, total organic carbon (TOC) and chemical oxygen demand (COD), as well as the generation of $NH_4^+$, $NO_3^-$ and $SO_4^{2-}$, were followed. SMX photolytic degradation efficiency followed the ranking: 254 nm lamps > sunlight > black-light blue (BLB) lamps (negligible for the latter). The highest eliminations were obtained by means of UV/$H_2O_2$ reaction in a lab-scale reactor (254 nm lamps) with an initial $H_2O_2$ concentration of 200 mg $L^{-1}$: ${\Delta}TOC$ = 62.3%; ${\Delta}COD$ = 79.1% (more than 6 h). Similar removals were achieved with a lab-scale photo-Fenton reactor (BLB lamps) but using 400 mg $L^{-1}$ of oxidant (94 min). The use of solar light appeared to be an interesting option since satisfactory results were obtained in the solar-based photo-Fenton experiments compared to the lab-scale ones, and also since a significant improvement with respect to the solar photolysis was achieved when performing the UV/$H_2O_2$ reaction with sunlight. Finally, some of the resultant effluents from different reactions were subjected to a short-term biodegradability test in order to estimate their quality from a biological point of view.

Blockade of cannabinoid 1 receptor improves GLP-1R mediated insulin secretion in mice

Gonzalez-Mariscal, I.,Krzysik-Walker, S.M.,Kim, W.,Rouse, M.,Egan, J.M. North-Holland 2016 Molecular and cellular endocrinology Vol.423 No.-

<P>The cannabinoid 1 receptor (CBI) is an important regulator of energy metabolism. Reports of in vivo and in vitro studies give conflicting results regarding its role in insulin secretion, possibly due to circulatory factors, such as incretins. We hypothesized that this receptor may be a regulator of the entero-insular axis. We found that despite lower food consumption and lower body weight postprandial GLP-1 plasma concentrations were increased in CB1(-/-) mice compared to CB1(+/+) mice administered a standard diet or high fat/sugar diet. Upon exogenous GLP-1 treatment, CB1(-/-) mice had increased glucose stimulated insulin secretion. In mouse insulinoma cells, cannabinoids reduced GLP-1R-mediated intracellular CAMP accumulation and subsequent insulin secretion. Importantly, such effects were also evident in human islets, and were prevented by pharmacologic blockade of CB1. Collectively, these findings suggest a novel mechanism in which endocannabinoids are negative modulators of incretin-mediated insulin secretion. (C) 2015 Elsevier Ireland Ltd.

Functional outcome predictors following mandibular reconstruction with osteocutaneous fibula free flaps: correlating early postoperative videofluoroscopic swallow studies with long-term clinical results

Gonzalez, Santiago R.,Hobbs, Bradley,Vural, Emre,Moreno, Mauricio A. Korean Association of Maxillofacial Plastic and Re 2019 Maxillofacial Plastic Reconstructive Surgery Vol.41 No.-

Background: Advancements in the field of microvascular surgery and the widespread adoption of microvascular surgical techniques have made the use of osteocutaneous fibula free flaps the standard of care in the surgical management of segmental mandibular defects. Although the literature possesses abundant evidence to support the effectiveness of fibula free flaps as a reconstructive method, there are relatively few studies reporting on outcomes as objectively measured by videofluoroscopic swallowing studies (VFSS). The purpose of this study is to explore the potential correlation between early postoperative VFSS and the long-term swallowing outcomes in patients who underwent mandibular reconstruction with fibula free flaps. Methods: We performed a retrospective chart review of 36 patients who underwent mandibular reconstruction with osteocutaneous fibular free flaps between 2009 and 2012. Demographics, clinical variables, VFSS data, and diet information were retrieved. Penetration and aspiration findings on VFSS, long-term oral feeding ability, and the need for gastrostomy tube were statistical endpoints correlated with postoperative clinical outcomes. Results: Thirty-six patients were reviewed (15 females and 21 males) with a mean age of 54 years (7-81). Seventeen cases were treated for malignancy. The size of the bony defect ranged from 3 to 15 cm (mean = 9 cm). The cutaneous paddle, a surrogate for soft tissue defect, ranged from 10 to 125 ㎠ (mean = 52 ㎠). A gastrostomy tube was present in patients preoperatively (n = 8), and postoperatively (n = 14). Seventeen patients had neoadjuvant exposure to radiation. Postoperative VFSS showed penetration in 13 cases (36%) and aspiration in seven (19%). Overall, 29 patients (80.6%) achieved unrestricted diet, and this was statistically correlated with age (p = 0.037), radiation therapy (p = 0.002), and preoperative gastrostomy tube (p = 0.03). The presence of penetration or aspiration on VFSS was a strong predictor for long-term unrestricted oral diet (p < 0.001). Conclusion: Early postoperative VFSS is an excellent predictor for long-term swallowing outcomes in patients undergoing mandibular reconstruction with osteocutaneous fibula free flaps.

Finite element modeling of manufacturing irregularities of porous materials

Gonzalez, Fernando J. Quevedo,Nuno, Natalia Techno-Press 2016 Biomaterials and biomedical engineering Vol.3 No.1

Well-ordered porous materials are very promising in orthopedics since they allow tailoring the mechanical properties. Finite element (FE) analysis is commonly used to evaluate the mechanical behavior of well-ordered porous materials. However, FE results generally differ importantly from experimental data. In the present article, three types of manufacturing irregularities were characterized on an additive manufactured porous titanium sample having a simple cubic unit-cell: strut diameter variation, strut inclination and fractured struts. These were included in a beam FE model. Results were compared with experimental data in terms of the apparent elastic modulus (Eap) and apparent yield strength (SY,ap). The combination of manufacturing irregularities that yielded the closest results to experimental data was determined. The idealized FE model resulted in an Eap one order of magnitude larger than experimental data and a SY,ap almost twice the experimental values. The strut inclination and fractured struts showed the strongest effects on Eap and SY,ap, respectively. Combining the three manufacturing irregularities produced the closest results to experimental data. The model also performed well when applied to samples having different structural dimensions. We recommend including the three proposed manufacturing irregularities in the FE models to predict the mechanical behavior of such porous structures.

An Array-Based Sensor for Seafood Freshness Assessment

Gonzalez-Martin, Anuncia,Lewis, Brian,Raducanu, Marius,Kim, Jin-Seong Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.11

This paper describes the development of an automated, hand-held sensor for the fast assessment of seafood freshness. The sensor developed here combined: an array-based chemical sensor, composed of incrementally different conducting polymer elements deposited on a small chip; a highly sensitive, custom-made electronics for the detection of very small signal changes; precise temperature control of the sensor chamber; and an on-board microcontroller for data collection, storage, automation, and analysis. The instrument was used to successfully test seafood samples with different degree of freshness and spoilage. A linear relationship between microbiological count and e-Nose signal for three different fish fillet was developed. Once the linear relationship is included into the hand-held unit software, the e-Nose signal can be used for assessment of seafood freshness without performing the microbiological count technique.

Clinical Update on Home Testing for Male Fertility

Gonzalez Daniel,Narasimman Manish,Best Jordan C.,Ory Jesse,Ramasamy Ranjith 대한남성과학회 2021 The World Journal of Men's Health Vol.39 No.4

Male factor infertility accounts for about 50% of the incidence of infertility in couples. In current practice, the men must attend a clinic or hospital facility to provide a semen analysis, which is key to the diagnosis of the male reproductive potential. However, many men are often embarrassed with the process and conventional semen analysis requires complex, labor intensive inspection with a microscope. To mitigate these problems, one of the solutions can be at-home semen analysis. In this review we examine the literature of currently available at home semen analysis test kits, describe their limitations, and compare them to the conventional lab-based methods.
