Objective: To compare the characteristics of double cream cheeses made with raw and pasteurized milk per liking and preference level. Design/Methodology/Approach: Cheeses from three brands were evaluated: Santa Teresa, Montero, and Colegio de Postgraduados (CP). The first two cheeses were formulated with raw milk, while the CP cheese was formulated with pasteurized milk inoculated with lactic cultures. The hedonic perception study was carried out in monadic series with 19 volunteers who blind tasted the three types of cheese. The evaluation attributes were: appearance, taste, aroma, and general acceptability on a 9-point scale; and saltiness, acidity, and creaminess on a 3-point scale (JAR). Preferences were evaluated by rank and multiple comparison tests. Results: No differences were found in the aroma, taste, and texture liking level of the cheeses (p>0.05); nevertheless, there were differences in the appearance and general acceptance (p˂0.05). The general acceptance of the CP cheese was significantly lower than that of the two raw milk cheeses (p˂0.05). The penalty analysis showed that low acidity and low creaminess attributes are related to a low general acceptance (p˂0.05). Limitations/Implications: The study has enough evaluations for statistical tests. Findings/Conclusions: Raw milk cheeses obtained the highest marks in all attributes. Determining if there are other sensory attributes —in addition to those that were the subject of this study— will help to explain the greater preference and global acceptance of raw milk cheeses.

Purpose The purpose of this paper is to examine the effect of health information and sensory attributes on consumer’s propensity to upgrade and their willingness to pay (WTP) for pasteurized milk in Ethiopia. Design/methodology/approach The authors used a framed market experiment with 160 participants in 14 central locations in urban Ethiopia. The authors used a double hurdle model to analyze consumer willingness to shift to pasteurized milk and their WTP for quality attributes in pasteurized milk. Findings Consumers are willing to pay a 4 percent premium for quality attributes in pasteurized milk. Male and employed participants are willing to shift and pay a premium for pasteurized milk. Conversely, consumers with more children, higher income, and higher raw milk consumption are less likely to shift to pasteurized milk. These results also show that taste is negatively related to consumer propensity to upgrade to pasteurized milk. Further, about half of the consumers who were provided with health information are willing to pay a premium of 11 percent for pasteurized milk, whereas others would pay only 6 percent. After providing the treatment group with health information, those consumers with higher income, old people and consumers with children are less likely to shift to pasteurized milk. Overall, consumer preference for raw milk is the result of taste, perceived nutrition and perceived health benefits. The study points at a segmented milk market and the consequent need for the provision of a targeted milk market promotion. Research limitations/implications The application of experimental auctions in developing countries requires an extensive learning exercise for participants. Originality/value The authors used a non-hypothetical valuation mechanism to unravel the effect of subjective and intrinsic milk attributes in fluid milk choice decisions and its variation across socio-economic groups in a developing country context.

Vietnamese sausage (cha lua), a pork processing food with a characteristic chewy and crunchy texture, are widely consumed in Vietnam. However, there are not many established researchs on hedonic and sensory attributes for this product, especially about the texture attributes. The goal of this study was to investigate consumer's preference as well as identify the drivers of liking for texture of Vietnamese sausage. Eight samples were prepared with various ratio of lean meat, lard and starch to cover a wide range of different texture of Vietnamese sausage. Sixty eight consumers then evaluated these eight samples, rating texture liking on nine-point scale and answering a checkall- that-apply (CATA) question, which consisted of 16 different texture attributes of Vietnamese sausage. The consumers were also asked to check all the approriate attributes to describe their ideal products. The ANOVA and post –hoc test showed samples which had recipes with high lard ratio (20-25%) and low meat ratio (70%) had a significant higher liking scores, while the samples which had recipe with high meat ratio (90%) had the lowest liking scores. The Cochran's Q test showed that 12 attributes had different choice frequency between samples, suggesting the texture of Vietnamese sausage is complex and diverse. The CA results showed all the samples without stach were associated with large air holes, while samples which high meat ratio (80%) were associated with hardness. The ideal Vietnamese sausage product was associated with fattiness, juiciness, springiness and brittleness. Finally, the results of penalty analysis showed that chewy, firm, and elastic attributes had positive impacts on the liking score for Vietnamese sausage products, while attributes that exhibit heterogeneity, such as large air hole and grainy, significantly reduced the liking score of the product. This suggested the importance of mechanical texture attributes and homogenity on the consumer's preference of the Vietnamese sausage.

The bans on visiting nursing homes during the COVID-19 pandemic, while intended to protect residents, also have the risk of increasing the loneliness and social isolation that already existed among the older generations before the pandemic. To combat loneliness and social isolation in nursing homes, this trial presents a study during which social networks of nursing home residents and elderly hospital patients were maintained through virtual encounters and robots, respectively. The observational trial included volunteers who were either residents of nursing homes or patients in a geriatric hospital. Each volunteer was asked to fill in a questionnaire containing three questions to measure loneliness. The questionnaire also documented whether video telephony via the robot, an alternative contact option (for example, a phone call), or no contact with relatives had taken place. The aim was to work out the general acceptance and the benefits of virtual encounters using robots for different roles (users, relatives, nursing staff, facilities). Seventy volunteers with three possible interventions (non-contact, virtual encounters by means of a robot, and any other contact) took part in this trial. The frequency of use of the robot increased steadily over the course of the study, and it was regularly used in all facilities during the weeks of visitor bans (n = 134 times). In the hospital, loneliness decreased significantly among patients for whom the robot was used to provide contact (F(1,25) = 7.783, p = 0.01). In the nursing homes, no demonstrable effect could be achieved in this way, although the subject feedback from the users was consistently positive.

Purpose – The purpose of this paper is to examine how the boundaries of rhetoric have excluded important theoretical and practical subjects and how these subjects are recuperated and extended since the twentieth century. Its purpose is to foster the awareness on emerging new trends of rhetoric. Design/methodology/approach – The methodology is based on an interpretation of the history of rhetoric and on the construction of a conceptual framework of the rhetoric of judgment, which is introduced in this paper. Findings – On the subject of the extension of rhetoric from public speeches to any kinds of persuasive situations, the paper emphasizes some stimulating relationships between the theory of communication and rhetoric. On the exclusion and recuperation of the subject of rhetorical arguments, it presents the changing relationships between rhetoric and dialectics and emphasizes the role of rhetoric in scientific research. On the introduction of rhetoric of judgment and meanings it creates a conceptual framework based on a re-examination of the concept of judgment and the phenomenological foundations of the interpretative methods of social sciences by Alfred Schutz, relating them to symbolic interactionism and theories of the self. Originality/value – The study on the changing boundaries of rhetoric and the introduction of the rhetoric of judgment offers a new view on the present theoretical and practical development of rhetoric, which opens new subjects of research and new fields of applications.

Purpose This paper aims to examine the challenges to sustaining corporate culture in a world of hybrid working. Design/methodology/approach This paper is a review of current literature on the impact of remote and hybrid working on white-collar employees. Findings There is little consensus on whether remote/hybrid working will harm or strengthen corporate culture. Research limitations/implications The viewpoint is a subjective assessment of a limited number of articles on the subject Practical implications It is not entirely clear how those responsible for corporate culture can act on the findings. Social implications In a world in which corporations are experiencing a shortage of talent, how they handle corporate culture will be increasingly important. Originality/value While much has been written on the impact of remote working, this viewpoint takes the original view that strong corporate cultures rely more on the attitudes and actions of individual employees that company programs or initiatives.

Aim: the aim of this study was to determine sensory profile, through the use of just-about-right (JAR) scales and penalty analysis, of Bobolo and Chikwangue from the cassava roots fermented with previously cassava-fermented chips powder (PCFCP). Furthermore, retting time, cyanide content and pasting properties of retted roots were evaluated. Methods: for that, two samples of Bobolo and Chikwangue obtained from two cassava retting methods were studied: a control made from the retting without PCFCP and a product made from retting with PCFCP. Results: retting time was carried out in 48 hours less with PCFCP and 60% of cyanide reduction more than control. No major modifications occurs in pasting properties of paste fermented with PCFCP. The sensory analysis indicated high levels of acceptability for products made from retting with PCFCP. The penalty analysis showed that attributes “too sour” and “too much fermented odor” affected the acceptability of the Bobolo from retting without PCFCP significantly. Conclusion: fermentation of cassava through the use of PCFCP is suitable to improvement of sensory characteristics of fermented cassava by-products.
