The influence of service brand equity on the strength of brand relationships in the fast food industry

The South African fast food industry is growing fast and rivals are competing fiercely, providing customers with an array of different choices. Given this situation, it has become increasingly important for fast food organisations to focus on elevating and sustaining a competitive advantage. One way of doing this is by maximising brand equity. In doing so, organisations can differentiate themselves in the minds of customers by encouraging a relationship with their brand. The aim of this study is to determine the influence of service brand equity on customers’ relationships with their fast food brand. The population comprised fast food customers residing in the North West Province of South Africa. A cross-sectional descriptive design was followed, and a convenience sample was used to select respondents. Data were obtained by means of a self-administered questionnaire, realising 379 responses. A multiple regression analysis indicates that three brand equity dimensions, namely brand awareness, brand association and brand trust, significantly and positively influence the strength of the relationships that respondents have with their favourite fast food brand (with brand trust being the most influential dimension). Fast food outlets can, therefore, strengthen their customers’ brand relationships by focusing specifically on improving these three dimensions.Key words: service brand equity, brand awareness, perceived quality, brand differentiation, brand associations, brand trust, brand relationships, fast food industry, fast food outlet

Regularization Methods for Ill-Posed Problems in Multiple Hilbert Scales

Several convergence results in Hilbert scales under different source conditions are proved and orders of convergence and optimal orders of convergence are derived. Also, relations between those source conditions are proved. The concept of a multiple Hilbert scale on a product space is introduced, regularization methods on these scales are defined, both for the case of a single observation and for the case of multiple observations. In the latter case, it is shown how vector-valued regularization functions in these multiple Hilbert scales can be used. In all cases convergence is proved and orders and optimal orders of convergence are shown.Comment: 32 pages, 2 figure

A Culturally and Linguistically Responsive Framework for Improving Academic and Postsecondary Outcomes of Students with Moderate or Severe Intellectual Disability

The needs of culturally and linguistically diverse (CLD) students with moderate or severe intellectual disability (ID) are quite unique and complex. CLD students with moderate or severe ID face many of the same issues as their non-disabled CLD peers; however, due to the nature of their disability this may lead to even less access to the general curriculum, appropriate services, materials, and meaningful collaboration between families and educators. The purpose of this article is to provide a culturally responsive framework for facilitating academic instruction for CLD students with moderate or severe ID that also includes appropriate supports in an effort to increase access to postsecondary outcomes for this population. Suggestions for accessing the general curriculum and a discussion about increasing parental involvement and accessing appropriate adult agencies to further enhance these outcomes are provided

Self-reported practices and emotions in prescribing opioids for chronic, noncancer pain: A cross-sectional study of German physicians

Background: The pressure on physicians when a patient seeks pain relief and their own desire to be self-effective may lead to the prescription of strong opioids for chronic noncancer pain (CNCP). This study, via physician self-reporting, aims to identify and measure (i) physician adherence to national opioid prescribing guidelines and (ii) physician emotions when a patient seeks a dosage increase of the opioid. Methods: Within a cross-sectional survey—conducted as part of a randomized controlled online intervention trial (ERONA)—600 German physicians were queried on their opioid prescribing behavior (choice and formulation of opioid, indications) for CNCP patients and their emotions to a case vignette describing a patient seeking an opioid dosage increase without signs of objective deterioration. Results: The prescription of strong opioids in this study was not always in accordance with current guidelines. When presented with a scenario in which a patient sought to have their opioid dose increased, some physicians reported negative feelings, such as either pressure (25%), helplessness (25%), anger (23%) or a combination. The risk of non-guideline-compliant prescribing behavior using the example of ultrafast-acting fentanyl for CNCP was increased when negative emotions were present (OR: 1.7; 95%-CI: 1.2–2.6; p = 0.007) or when sublingual buprenorphine was prescribed (OR: 15.4; 95%-CI: 10.1–23.3; p < 0.001). Conclusions: Physicians’ emotional self-awareness represents the first step to identify such direct reactions to patient requests and to ensure a responsible, guideline-based opioid prescription approach for the long-term well-being of the patient

A structural and dynamic model for the assembly of Replication Protein A on single-stranded DNA

Replication Protein A (RPA), the major eukaryotic single stranded DNA-binding protein, binds to exposed ssDNA to protect it from nucleases, participates in a myriad of nucleic acid transactions and coordinates the recruitment of other important players. RPA is a heterotrimer and coats long stretches of single-stranded DNA (ssDNA). The precise molecular architecture of the RPA subunits and its DNA binding domains (DBDs) during assembly is poorly understood. Using cryo electron microscopy we obtained a 3D reconstruction of the RPA trimerisation core bound with ssDNA (∼55 kDa) at ∼4.7 Å resolution and a dimeric RPA assembly on ssDNA. FRET-based solution studies reveal dynamic rearrangements of DBDs during coordinated RPA binding and this activity is regulated by phosphorylation at S178 in RPA70. We present a structural model on how dynamic DBDs promote the cooperative assembly of multiple RPAs on long ssDNA

Cellulose lattice strains and stress transfer in native and delignified wood

Small specimens of spruce wood with different degrees of delignification were studied using in-situ tensile tests and simultaneous synchrotron X-ray diffraction to reveal the effect of delignification and densification on their tensile properties at relative humidity of 70–80 %. In addition to mechanical properties, these analyses yield the ratio of strains in the cellulose crystals and in the bulk, which reflects the stress-transfer to crystalline cellulose. While the specific modulus of elasticity slightly increases from native wood by partial or complete delignification, the lattice strain ratio does not show a significant change. This could indicate a compensatory effect from the decomposition of the amorphous matrix by delignification and from a tighter packing of cellulose crystals that would increase the stress transfer. The reduced strain to failure and maximum lattice strain of delignified specimens suggests that the removal of lignin affects the stress-strain behavior with fracture at lower strain levels
