Tidskriftsartikel (refereegranskat)abstract
- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Forskningsöversikt (refereegranskat)abstract
- The stereotypes content model indicates that two traits (i.e., warmth and competence) govern individuals' impression formation. The great variety of research that has used this theory since the early 2000s leads to a need for a structured overview of prior findings. The goal of this study is to provide a concise map of research streams and present a research agenda. We conducted a systematic literature review of 955 articles. A bibliographic coupling analysis showed four clusters, i.e., (1) the general theoretical foundations of the SCM, (2) the societal impact of key stereotypes (with emphasis on gender), (3) research in clinical psychology and child development, and (4) marketing. Taking a closer look at research in marketing (using co-occurrence analysis), six research streams were identified, including research on branding, country-of-origin, front-line service providers, prosocial consumer behavior, perception of endorsers, and, more recently, on artificial intelligence (AI). The review presents key findings and research gaps across these topics. Finally, we reviewed the few articles that, although not falling into these streams, opened important research veins. This process provided the essential information to present a promising and complete research agenda, to continue building knowledge with impactful implications in different contexts.

- En esta investigación se analiza el uso de las fuentes de información y su incidencia en distintas etapas del proceso de decisión de los turistas en Valencia (España). Tras la realización de una investigación de corte cuantitativo, utilizando un cuestionario estructurado, y el análisis de los datos a través de estadísticos descriptivos y pruebas de diferencia de medias, los resultados muestran que el uso de fuentes de información, la intensidad la búsqueda y la importancia otorgada a las fuentes, cambia en función del momento en que se encuentra el turista respecto a sus vacaciones. Posteriormente, se especifican cuáles son estas diferencias y en qué radica su importancia para la gestión en el ámbito turístico.

- Este trabajo analiza los efectos de las variables subyacentes de una situación crisis económica sobre el estrés del personal de ventas; específicamente se examina el caso de España. Para ello, se realizaron 150 encuestas a vendedores en la ciudad de Valencia, y se examinó el estrés y su relación con variables derivadas de la crisis. La relación entre los constructos se analizó a través de un Análisis Factorial Confirmatorio y Ecuaciones Estructurales. Los resultados indican que la percepción de un entorno poco estable y que ofrece pocas posibilidades laborales ejerce una influencia sobre el estrés de la fuerza de ventas. Por otro lado, muchos de los vendedores contratados por las empresas en la actualidad española han sido formados en otras áreas y sienten una baja identificación con el puesto de trabajo, lo que también provoca un aumento de estrés. Con base en los resultados, la investigación concluye con una serie de directrices para mejorar la gestión en relación con la temática de análisis.

- The dimensions and effects of the construct “child routine” have been broadly investigated in the field of social psychology. Three studies were conducted to adapt this construct to the field of human–animal relationships and to measure dog routine. The procedure included the initial item generation and item reduction process. Study 1 was conducted to examine the dimensionality, reliability, and validity of the scale. A total of 245 dog owners from Bogotá (Colombia) participated in this study. The results revealed four dimensions to measure the construct: (1) daily activities, (2) exercise, (3) discipline, and (4) family time. The reliability and validity of the scale were accepted. Study 2 was conducted to test the reliability of the scale in another country and in a different language (German). This study included an analysis of the nomological validity of the scale by examining the association between dog routine and canine behavioral problems. A total of 154 dog owners from Ingolstadt (Germany) participated in this study. The results supported the reliability and validity of the scale. Additionally, the results showed that a consistent routine is associated with reduced behavioral problems. Study 3 was performed to validate the scale in a third language (English) and to examine the associations between dog routine and behavioral problems, owner satisfaction, and intention to abandon the dog. A total of 182 English-speaking dog owners from Ingolstadt (Germany) participated in this study. The results showed that a consistent routine is associated with reduced behavioral problems, which is associated with higher owner satisfaction and reduced intention to abandon the animal. The implications of these results in the field of human–animal relationships and thoughts on future research are presented.

Differences among generations of USA tourists regarding the positive content created about Colombia in social media

Tidskriftsartikel (refereegranskat)abstract
- This research analyzes if generational segmentation moderates the relationships among self-congruity, nation brand, destination brand and the use of social media by USA tourists to create positive content about Colombia. Using the methodology of SEM, the results show that experience self-congruity influences the perception of the destination brand and the content created in social media about Colombia. Also, a positive perception of the nation brand motivates the creation of positive content about the country. Using an invariance test and a multi-group analysis, it was found that the relationship between self-congruity and the positive content created on social media can only be accepted among Generation Y tourists. Furthermore, the relationship between nation brand, destination brand and the content created on social media can only be accepted among Generation X tourists. The conclusions of the paper present the managerial implications of these findings.
