Immigrants face an array of disruptions, including changes in social and religious contexts, values, norms, beliefs, behaviors, that are constantly threatening their self and social identities. How they manage those threats is crucial to their adaptation to the new cultural context, and is the main investigation of this research. Specifically, we investigated how Muslim immigrants react when they see themselves transgressing one of their cultural values. Results of Study 1 provide full support to our hypotheses that when people see themselves transgressing their in-group values, they are more concerned when the transgressing behavior is witnessed by an out-group than an in-group member. In other words, they demonstrate to be more worried in preserving the in-group image in front of an out-group member than in preserving their self-image in front of an in-group member. Further results of Study 1 also showed evidence of a new type of value affirmation mechanism. The negative emotional reaction to the transgressing behavior was reduced when the out-group member was said to have endorsed the transgressing-related cultural value.

A mathematical model was developed to predict breakthrough curves during purification of the two chitosanasesfrom Metarhizium anisopliae by expanded bed adsorption, taking into account the axial dispersion of liquid andusing Streamline DEAE and SP XL adsorbents, anion and cation exchange resins, respectively. All the experimentswere performed without clarification (with cells) aiming at the reduction of unit operations in future projects of separationprocesses, thereby reducing capital and operating costs. Chitosanases are enzymes that hydrolyze the carbohydratechitosan, resulting in oligosaccharides that have many remarkable biological activities, such as anti-cancer, anti-HIVand antioxidant activities. The two adsorbents had similar performance in relation to hydrodynamics and mass transfer. The results of the parametric sensitivity analysis agree with the literature, and the model was validated with an averagehigh degree of fit (94.68%) between simulated and experimental data obtained in this work.

( Yunyoung Hur ),( Seowoo Nam ),( Sergio W. Carvalho ) 서암순창장학회 2014 Journal of Marketing Thought Vol.1 No.3

The purpose of this study is to identify the key factors that contribute to the success of B2B e-marketplace platforms. A survey was administered in schools that use a food e-procurement system, a type of B2B e-marketplace platform. Survey findings showed that among the suggested contributors of success, perceived value and customer trust towards the system are directly correlated with customer loyalty and willingness to continue to participate. Other factors indirectly influence customer loyalty by affecting perceived value and consumer trust. Specifically, perceived ease of use and interaction among participants are positively related to perceived value of the e marketplace, whereas interaction and information sharing significantly influence the level of trust.

THE NEGATIVE IMPACT OF USING DISLIKED BRANDS IN DIGITAL BRAND PLACEMENTS

Justin F. McManus,Sergio W. Carvalho,Valerie Trifts 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

Consumers may not be fully aware of the level of personalization used in brand placements in digital advertising. Personalized brand placements use customer data to select and insert preferred brands into digital media content, such as having Coke appear in a YouTube video for someone who favors Coca-Cola. This personalization can enhance the consumer experience (Trifts & Aghakhani, 2018) but may also backfire if placements don't account for changes in brand preference or when personalized placements are co-consumed with a person whose preferences strongly diverge from one’s own (e.g., one’s romantic partner; Brick, Fitzsimons, Chartrand, & Fitzsimons, 2018). Brands have a significant impact on how people perceive each other. Brands convey social information and symbolic meaning (Keller, 1993; Levy, 1959) and can influence behavior (e.g., Fitzsimons, Chartrand, & Fitzsimons 2008) and provide a source of affiliation (Escalas & Bettman, 2003). However, less is known about how brands affect basic social connections like empathy. This notable gap is relevant to the evaluation of the impact of brand placements in digital advertising as brand logos are quite visible in brand placements and can be the first piece of information someone observes when forming an attitude towards another person. For example, imagine an Instagram post of a person wearing a Harley Davidson baseball cap. What kind of person did you imagine? Does your impression change if, instead, the brand was People for the Ethical Treatment of Animals, or the Trump Organization? Moreover, how likely would you be to engage with media showcasing a person supporting this brand. In the current research, we propose that personally disliked brands create a negative bias in person perception and consumer judgment, a phenomenon we coin “brand negativity bias.” Our results show that disliking a brand can reduce empathy for others and substantially bias attitudes toward a digital product associated with but not created by the brand. Specifically, we show process evidence that suggests disliked brand placements reduce (1) empathy toward others through reductions in perceived similarity and (2) attitudes toward a digital product through perceived similarity and empathy, as serial processes. In addition, although we do not empirically test an overall mechanism that explains the negativity bias in its entirety, we speculate several reasons that underlie the broad influence of personally disliked brands (e.g., symbolic, ideological, or moral). From a societal point of view, our findings inform the public to be mindful of how simple consumption cues can bias people’s decision making, which holds implications beyond consumer judgment in domains involving first impressions.

Background: The use of agroindustrial by-products in ruminant nutrition to be an interesting alternative in order to reduce production costs and environmental impacts arising from the inadequate destination of residues. The initial step of beer production yields a large volume of wet brewer’s grains all year around, which is available at a low cost and has a high nutritional quality, and hence a big potential for animal production. Methods: Twenty-four Suffolk non-castrated male lambs, from simple parturition were kept in individual spots and allocated to four treatments constituted by four levels of substitution of sorghum silage by WBG (i.e.0; 33.5; 66.5 and 100% of substitution). It was used roughage: concentrate rate of 50:50, based on dry matter. Results: The ether extract intake increased while the acid detergent fiber intake decreased linearly (P ≤ 0.05). Substituion of sorghum silage by WBG did not change lambs’ feed DMI, daily weight gain and feed conversion. Conclusion: The substitution of sorghum silage by WBG as roughage showed to be a viable alternative from the productive and economic point of view for finishing of feedlot lambs.

Cone-beam computed tomography artifacts in the presence of dental implants and associated factors: An integrative review

Terrabuio, Bianca Rodrigues,Carvalho, Caroline Gomes,Peralta-Mamani, Mariela,da Silva Santos, Paulo Sergio,Rubira-Bullen, Izabel Regina Fischer,Rubira, Cassia Maria Fischer Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.2

Purpose: This study was conducted to review the literature regarding the types of cone-beam computed tomography (CBCT) artifacts around dental implants and the factors that influence their formation. Materials and Methods: A search strategy was carried out in the PubMed, Embase, and Scopus databases to identify published between 2010 and 2020, and 9 studies were selected. The implants included 306 titanium, titanium-zirconium, and zirconia implants, as well as 5 titanium cylinders. Results: The artifacts around the implants were the beam-hardening artifact, the streaking artifact, and band-like radiolucent areas. Some factors that influenced the formation of artifacts were the implant material, bone type, evaluated regions, distance, type of CBCT, field of view (FOV) size, milliamperage, peak kilovoltage (kVp), and voxel size. The beam-hardening artifact was the most widely reported, and it was minimized in protocols with a smaller FOV, larger voxels, and higher kVp. Conclusion: The risk and benefit of these protocols in individuals with dental implants must be considered, and clinical examinations and complementary radiographs play an essential role in implantology.

Application of a newly developed software program for image quality assessment in cone-beam computed tomography

de Oliveira, Marcus Vinicius Linhares,Santos, Antonio Carvalho,Paulo, Graciano,Campos, Paulo Sergio Flores,Santos, Joana Korean Academy of Oral and Maxillofacial Radiology 2017 Imaging Science in Dentistry Vol.47 No.2

Purpose: The purpose of this study was to apply a newly developed free software program, at low cost and with minimal time, to evaluate the quality of dental and maxillofacial cone-beam computed tomography (CBCT) images. Materials and Methods: A polymethyl methacrylate (PMMA) phantom, CQP-IFBA, was scanned in 3 CBCT units with 7 protocols. A macro program was developed, using the free software ImageJ, to automatically evaluate the image quality parameters. The image quality evaluation was based on 8 parameters: uniformity, the signal-to-noise ratio (SNR), noise, the contrast-to-noise ratio (CNR), spatial resolution, the artifact index, geometric accuracy, and low-contrast resolution. Results: The image uniformity and noise depended on the protocol that was applied. Regarding the CNR, high-density structures were more sensitive to the effect of scanning parameters. There were no significant differences between SNR and CNR in centered and peripheral objects. The geometric accuracy assessment showed that all the distance measurements were lower than the real values. Low-contrast resolution was influenced by the scanning parameters, and the 1-mm rod present in the phantom was not depicted in any of the 3 CBCT units. Smaller voxel sizes presented higher spatial resolution. There were no significant differences among the protocols regarding artifact presence. Conclusion: This software package provided a fast, low-cost, and feasible method for the evaluation of image quality parameters in CBCT.
