Resource-based theory in marketing
The use of resource-based theory (RBT) in marketing research has increased by more than 500% in the past decade, which suggests its importance as a framework for explaining and predicting competitive advantages and performance outcomes. This article provides a comprehensive review of RBT, including a contemporary definitional foundation for relevant terms and assumptions and a synthesis of empirical findings from marketing literature. This multidimensional analysis of RBT also evaluates extant marketing research according to four perspectives: the marketing domains that use RBT, the characteristics and uses of market-based resources that differentiate it from other research contexts, the extension of RBT to the “marketing exchange” as a unit of analysis, and the connection of RBT to related theories. This analysis also reveals some common pitfalls associated with prior research, offers tentative guidelines on how to improve the use of RBT in marketing, and suggests research directions to advance the theorization and empirical testing of RBT in the future.
Behavioural determinants of livestock farmers and seroprevalence of brucellosis in small ruminants in the subprefecture of Dounet (Mamou), Republic of Guinea
This study assessed the brucellosis seroprevalence of small ruminants and hazardous practices of contamination in the sub-prefecture of Dounet in Guinea. A survey was carried out among 60 people, mainly livestock farmers, and 192 small ruminants were clinically examined. Ninety serum samples were subjected to the Rose Bengal Test (RBT) and Indirect Enzyme-Linked Immunosorbent Assay (I-ELISA). Abortion and sterility were the most commonly observed symptoms, with 73.33% and 18.18%, respectively, for goats, and 81.82% and 26.67% for sheep. Farmers’ knowledge about brucellosis in small ruminants was significantly lower (18.33% [9.9%–30.85%]). Regarding sanitary measures to prevent disease occur-rence, 31.67% [20.60%–45.09%] of the farmers did not apply any specific measures, compared to 55% who applied sanitary measures and 8% who applied quarantine. The results of RBT showed that the overall seroprevalence of brucellosis was 27.77% (25/90) compared to 11.11% (10/90) using I-ELISA (p = 0.008). Female goats were significantly more affected, with a prevalence of 85% (17/20) compared with 20% (3/15) in males (p < 0.001). Bacterial infection did not vary significantly between study sites or age groups. The results of this study confirm that brucellosis is widespread among small ruminants and underline the urgent need for increased surveillance of the disease in all regions of the country.
Brand resource orchestration: a strategic framework for managing brands
Objective: This article aims to identify the branding resources and capabilities and their inter-relations, proposing a new framework called Brand Resource Orchestration (BRO). Brands need to be unique in the eyes of consumers and different from competitors to be a source of value for companies. Method: This study used the Design Science Research (DSR) method to build the framework, identifying resources and capabilities from the literature review and scrutinising them in interviews with marketing managers, directors, consultants, and professors. Originality/Relevance: Extensive research discussed the meaning of brands and the creation of their identities, depicted in several brand identity models. However, there is a gap in academic studies in branding and strategic marketing regarding the orchestration of resources and capabilities. Findings: Our proposed framework has four dimensions: organisation, brand identity, brand positioning, market environment, and brand results. Theoretical and Managerial Contributions: We integrate branding theory and marketing capabilities with Resource-Based Theory (RBT) and resource orchestration, providing a new framework to organise capabilities and resources related to brand management.
Diagnostic Performance of Rose Bengal, Competitive ELISA, and Native Hapten (NH) Assays in S19 Mass‐Vaccinated Cattle in an Endemic Brucellosis Environment
Controlling bovine brucellosis requires reliable diagnostics and effective vaccination strategies. We evaluated the performance of three serological assays—the rose bengal test (RBT), competitive ELISA (cELISA), and agar gel immunodiffusion (AGID) with native hapten (NH)+lipopolysaccharide (LPS) antigen—following Brucella abortus S19 vaccination under different protocols. Serum samples were collected from two cattle populations in Costa Rica: (i) a brucellosis‐free cohort of 25 heifers (Farm 1) vaccinated once with a reduced dose of S19 (5 × 10 9 CFU) via either the conjunctival ( n = 5) or subcutaneous ( n = 20) route, and (ii) a previously vaccinated herd with B. abortus RB51 (Farm 2) of 253 cattle, cleared of Brucella infection by test and slaughter, was then vaccinated with S19 (either 5 × 10 10 or 5 × 10 9 CFU, conjunctival or subcutaneous). All sera were tested by RBT, cELISA, and AGID using standard procedures. In validation with control sera, RBT, cELISA, and AGID NH+LPS each correctly identified all 35 positive and all 35 negative sera, while AGID NH+LPS correctly identified 33 of 35 positive sera and all negative sera. In Farm 1, conjunctival vaccination induced only a transient antibody response: all heifers were seronegative by 7 weeks postvaccination, and none developed NH‐specific precipitin lines. Subcutaneous vaccination produced stronger and longer‐lasting responses: ~20% of animals remained RBT/cELISA‐positive at 1 year (5% at 2 years), though none reacted to NH. In Farm 2, S19 vaccination elicited sustained RBT and cELISA seropositivity, especially after subcutaneous administration. About 5% of animals developed NH‐specific precipitin lines over time, consistent with an anamnestic response to residual infection. These findings show that vaccination route affects serological outcomes: conjunctival S19 vaccination yields minimal long‐term interference, while subcutaneous vaccination prolongs seropositivity. The AGID NH+LPS test helped identify actively infected animals in vaccinated herds. We recommend S19 mass vaccination via the conjunctival route and caution against using cELISA as a routine confirmatory test following RBT in endemic settings.
Resource type and SME alliance formation: the contingent role of perceived environmental uncertainty
PurposeThe aim of the study was to determine how the different types of resources possessed by a small- and medium-sized enterprise (SME), in conjunction with the environmental uncertainty perceived by the SME's managers, affect SME's alliance formation.Design/methodology/approachPersonal interview method was used to collect responses to a survey instrument from Indian SMEs. Logistic regression technique was used to analyze the responses obtained from 127 manufacturing enterprises.FindingsThe study finds that while both tangible and intangible resources possessed by an enterprise positively influence the enterprise's alliance formation, the influence of intangible resources is significantly stronger. The authors also observed the interactive effect between each resource type and environmental uncertainty to be a significant predictor of alliance formation.Research limitations/implicationsThe study does not account for temporal effects such as changes in resources and perceived environmental uncertainty, which may affect alliance formation. Similarly, because the data were obtained from a geographically restricted sample, replication of the study in other geographies may be necessary for generalizing the results.Originality/valueThe paper responds to the call for research to link firm resources and perceived environmental uncertainty toward explaining alliance formation by SMEs. The study went beyond making a distinction between the two types of resources by explicating how the interaction of resource type and environmental uncertainty will affect alliance formation.
Use of Magnetic Resonance Imaging for Evaluating Residual Breast Tissue After Robotic-Assisted Nipple-Sparing Mastectomy in Women With Early Breast Cancer
Prospective studies on postoperative residual breast tissue (RBT) after robotic-assisted nipple-sparing mastectomy (R-NSM) for breast cancer are limited. RBT presents an unknown risk of local recurrence or the development of new cancer after curative or risk-reducing mastectomies. This study investigated the technical feasibility of using magnetic resonance imaging (MRI) to evaluate RBT after R-NSM in women with breast cancer. In this prospective pilot study, 105 patients, who underwent R-NSM for breast cancer at Changhua Christian Hospital between March 2017 and May 2022, were subjected to postoperative breast MRI to evaluate the presence and location of RBT. The postoperative MRI scans of 43 patients (age, 47.8 ± 8.5 years), with existing preoperative MRI scans, were evaluated for the presence and location of RBT. In total, 54 R-NSM procedures were performed. In parallel, we reviewed the literature on RBT after nipple-sparing mastectomy, considering its prevalence. RBT was detected in 7 (13.0%) of the 54 mastectomies (6 of the 48 therapeutic mastectomies and 1 of the 6 prophylactic mastectomies). The most common location for RBT was behind the nipple-areolar complex (5 of 7 [71.4%]). Another RBT was found in the upper inner quadrant (2 of 7 [28.6%]). Among the six patients who underwent RBT after therapeutic mastectomies, one patient developed a local recurrence of the skin flap. The other five patients with RBT after therapeutic mastectomies remained disease-free. R-NSM, a surgical innovation, does not seem to increase the prevalence of RBT, and breast MRI showed feasibility as a noninvasive imaging tool for evaluating the presence and location of RBT.
Understanding Barriers and Facilitators of Parent/Caregiver Involvement in Home-Based Applied Behavioral Analysis Programming for Their Autistic Child
There is a need for more attention to the importance of substantial parent involvement in programming for autistic children in community-based care. More encouragement is needed to ensure that practitioners prioritize parental training and involvement throughout interventions, including practitioner-led in-home applied behavioral analysis (ABA) interventions. There has been little to no research on the feasibility and efficacy of adding parental training to in-home practitioner-led ABA interventions. This study is intended to begin the consideration of efficacy by reporting on a series of focus groups involving parents of autistic children and the Board Certified Behavioral Analysts (BCBAs) and Registered Behavior Technicians (RBTs) who work with them. Method: Focus group meetings were conducted with a total of 18 participants: 7 family members, 5 RBTs, and 6 BCBAs drawn from two provider sites. Transcripts were generated, and data was analyzed using Braun & Clarke’s reflexive thematic analysis, a method for analyzing and interpreting qualitative data that involves systematically generating codes in order to develop themes. Findings: The findings are described using three main themes: (1) barriers to family involvement in applied behavioral analysis programming, (2) facilitators of family involvement in applied behavioral analysis programming, and (3) recommendations for improving family involvement in applied behavioral analysis programming. Conclusions: There are logistical challenges in involving parents in in-home interventions when they occur in evening hours when the family has multiple other responsibilities. However, being in-home also presents opportunities not available in school or clinic settings. The recommendations provided offer an initial road map to advancing parent training components.
An Epidemiological Study of Brucellosis in Different Animal Species from the Al-Qassim Region, Saudi Arabia
Brucellosis is a zoonotic bacterial illness that affects humans and a variety of domestic animals, especially ruminants. It is mostly transmitted through the consumption of contaminated drinks, foods, undercooked meat, or unpasteurized milk or contact with infected animals. Therefore, the present study aimed to investigate the seroprevalence of brucellosis in camels, sheep, and goat herds in the Qassim region, Saudi Arabia, using commonly used diagnostic serological procedures such as the Rose Bengal test (RBT), complement fixation test (CFT), and enzyme-linked immunosorbent assay (ELISA). The seroprevalence of brucellosis in camels, sheep, and goats was determined in the selected areas using a cross-sectional study design and a total of 690 farm animals of both sexes of different ages from the three animal species (274 camels, 227 sheep, and 189 goats). According to RBT results, 65 sera were positive for brucellosis, including 15 (5.47%) for camels, 32 (14.09%) for sheep, and 18 (9.50%) for goats. CFT and c-ELISA were performed as confirmatory tests on positive samples resulting from RBT. With c-ELISA, 60 serum samples were confirmed positive, in 14 (5.10%), 30 (13.21%), and 16 (8.46%) camels, sheep, and goats, respectively. There were 59 serum samples confirmed as positive for CFT, including 14 (5.11%), 29 (12.77%), and 16 (8.46%) for camels, sheep, and goats, respectively. Overall, the highest seroprevalence of brucellosis was found in sheep while the least was found in camels from the three tests (RBT, c-ELISA, and CFT). The highest seroprevalence of brucellosis was found in sheep while the least seroprevalence was found in camels. There was also a higher seroprevalence of brucellosis among female animals than males as well as among old animals than young animals. The study, thus, demonstrates brucellosis seroprevalence among farm animals (camels, sheep, and goats) and the significance of intervention measures against brucellosis incidence in both humans and animals through the creation of public awareness and other relevant policy measures such as livestock vaccination, effective hygiene management, and adequate quarantine or serological analysis for newly introduced animals.
The effects of neurocognitive training on pain, proprioception, injury anxiety, and functional and neurocognitive performance in athletes with chronic ankle instability- randomized controlled trial
Considering the rapid motor-cognitive changes and increased risk of injury in preadolescent athletes, this study investigated the effects of neurocognitive training (NT) on pain, proprioception, injury-related anxiety, and functional and neurocognitive performance in athletes with chronic ankle instability (CAI). Randomized controlled trial. Sports training facilities in Balıkesir, Türkiye. Thirty preadolescent athletes with CAI (mean age 11.10 ± 1.06 years) were randomly assigned to an NT group (n = 15) or a control group (n = 13). The Identification of Functional Ankle Instability (IdFAI), Cumberland Ankle Instability Tool (CAIT), pain severity, proprioception (dorsiflexion/plantarflexion), injury-related anxiety, Y Balance Test (YBT), Side Hop Test, Reactive Balance Test (RBT), and Upper Extremity Choice Reaction Time Test were evaluated pre- and post-intervention. The NT group demonstrated significant improvements in IdFAI (p < 0.001), CAIT (p = 0.004), dorsiflexion (p = 0.003) and plantarflexion proprioception (p = 0.018), injury-related anxiety (p = 0.013), YBT anterior reach (p = 0.048), RBT reaction time (p = 0.030), and accuracy (p = 0.003). The control group showed improvement only in plantarflexion proprioception (p = 0.028), with an increase in post-training pain (p = 0.030). NT reduced ankle instability symptoms and injury-related anxiety while improving proprioception and neurocognitive performance. NT may enhance functional adaptation by addressing sport-specific cognitive-motor demands. •NT reduced instability severity and injury-related anxiety in CAI athletes.•Proprioception and neurocognitive performance significantly improved after NT.•NT enhanced reactive balance and reduced lateral hop test time.•Control group showed limited gains in proprioception and post-training pain.•NT may support multidimensional rehab by targeting both motor and cognitive skills.
Engagement and Social Impact in Tech-Based Citizen Science Initiatives for Achieving the SDGs: A Systematic Literature Review with a Perspective on Complex Thinking
Recent years have witnessed significant achievements and technological advances in citizen science (CS) projects; nevertheless, significant global challenges are present. Proof of this is in the joint efforts of international organizations to achieve the 2030 SDG agenda in a complex environment. Thus, UNESCO has recognized CS as being among the initiatives that could bridge the Science, Technology, and Innovation gap as a substantial resource, given its power to bring the general public closer together. Although tech-based CS projects keep rising, there is limited knowledge about which type of projects might allow participants to develop higher-order complex thinking skills. To that end, this study describes a systematic literature review (SLR) and analysis of 49 CS projects over the last 5 years concerning the technology utilized, the level of citizen involvement, and the intended social impact. The results of the analysis evidenced: (a) broad implementation in Europe on issues of the built environment, disaster risk, and environmental and animal monitoring; (b) prevalence of helix configurations other than the triple, quadruple, and quintuple helix innovation models; (c) a focus on technological developments to improve living conditions in cities; (d) an opportunity to develop applied native technologies; (e) limited development of participants’ complex thinking, when constrained to low levels of involvement; and (f) an opportunity to develop native technologies and promote a higher level of citizen participation, leading to more significant impact whilst developing complex thinking.
