Institutional Complexity and the Authenticity of Corporate Social Responsibility Initiatives

Stakeholders frequently regard CSR initiatives as inauthentic gestures even when the corporation is trying to behave responsibly. In this study we develop theory about which initiatives are likely to be viewed as authentic or not by which observers, when and why. We draw on concepts of authenticity from marketing and prior work on CSR, and on theories of institutional pluralism and institutional complexity as the basis for our propositions. We propose that different institutional logics value different criteria for assessing authenticity, and develop a model to explain how level of agreement on these criteria comes about and leads to varying outcomes in terms of perceived authenticity

Authenticity, Power, and Pluralism: A Framework for Understanding Stakeholder Evaluations of Corporate Social Responsibility Activities

We explore the essential contestedness of corporate social responsibility (CSR) by framing the interplay between CSR activities and st akeholder evaluations as a contest for jurisdiction over what it means to be socially resp onsible. This contest arises because firms and stakeholders are often guided by incompatible sense making systems. To show why context matters we show how stakeholders evaluate the authe nticity of CSR activities on the basis of schemas for responsible behavior on one hand and th eir perceptions of firm identity on the other. This process can generate complex evaluations whose meaning depends on the distribution of power in fields and the extent to which pluralistic sensemaking systems are compatible. By positioning authenticity evaluations within a frame work that describes the state of power and pluralism within which they are produced, we are ab le to present a systematic explanation of how and why stakeholder responses to CSR vary over a range of settings

Highly syntenic and yet divergent: a tale of two Theilerias

The published genomic sequences of the two major host-transforming Theileria species of cattle represent a rich resource of information that has allowed novel bioinformatic and experimental studies into these important apicomplexan parasites. Since their publication in 2005, the genomes of T. annulata and T. parva have been utilised for a diverse range of applications, ranging from candidate antigen discovery to the identification of genetic markers for population analysis. This has led to advancements in the quest for a sub-unit vaccine, while providing a greater understanding of variation among parasite populations in the field. The unique ability of these Theileria species to induce host cell transformation is the subject of considerable scientific interest and the availability of full genomic sequences has provided new insights into this area of research. This article reviews the data underlying published comparative analyses, focussing on the general features of gene expression, the major Tpr/Tar multi-copy gene family and a re-examination of the predicted macroschizont secretome. Codon usage between the Theileria species is reviewed in detail, as this underpins ongoing comparative studies investigating selection at the intra- and inter-species level. The TashAT/TpshAT family of genes, conserved between T. annulata and T. parva, encodes products targeted to the host nucleus and has been implicated in contributing to the transformed bovine phenotype. Species-specific expansion and diversification at this critical locus is discussed with reference to the availability, in the near future, of genomic datasets which are based on non-transforming Theileria species

Touching Holograms: A Preliminary Evaluation of Mixed Reality Gestures

Mixed reality is an emergent form of immersive technology that allows users to interact with and manipulate 3D digital objects and information using hand gestures. Whether it is replying to emails or playing a game, mixed reality devices require the use of gestures to complete such tasks. The Microsoft HoloLens 2 is a mixed reality head-mounted display that has been gaining popularity across many domains due to its enterprise-ready applications. These forms of technology provide opportunities to introduce new work environments and techniques of interaction with native hand tracking that may significantly impact the user experience. Previous studies on gesture control in the Microsoft HoloLens 1 showed improved performance after approximately 5 minutes of practice. As the HoloLens 2 has enhanced and implemented further gestures, this study reported on the investigation of various gesture interactions common to student-centered tasks. Results of the overall user experience, intuitiveness, and user perceptions of different gestures are discussed as they apply to the future of work with mixed reality

Reproducibility of aortic intima-media thickness in infants using edge-detection software and manual caliper measurements

Background: Aortic intima-media thickness measured by transabdominal ultrasound (aIMT) is an intermediate phenotype of cardiovascular risk. We aimed to (1) investigate the reproducibility of aIMT in a population-derived cohort of infants; (2) establish the distribution of aIMT in early infancy; (3) compare measurement by edge-detection software to that by manual sonographic calipers; and (4) assess the effect of individual and environmental variables on image quality. Methods. Participants were term infants recruited to a population-derived birth cohort study. Transabdominal ultrasound was performed at six weeks of age by one of two trained operators. Thirty participants had ultrasounds performed by both operators on the same day. Data were collected on environmental (infant sleeping, presence of a sibling, use of sucrose, timing during study visit) and individual (post-conception age, weight, gender) variables. Two readers assessed image quality and measured aIMT by edge-detection software and a subset by manual sonographic calipers. Measurements were repeated by the same reader and between readers to obtain intra-observer and inter-observer reliability. Results: Aortic IMT was measured successfully using edge-detection in 814 infants, and 290 of these infants also had aIMT measured using manual sonographic calipers. The intra-reader intra-class correlation (ICC) (n = 20) was 0.90 (95% CI 0.76, 0.96), mean difference 1.5 μm (95% LOA -39, 59). The between reader ICC using edge-detection (n = 20) was 0.92 (95% CI 0.82, 0.97) mean difference 2 μm (95% LOA -45.0, 49.0) and with manual caliper measurement (n = 290) the ICC was 0.84 (95% CI 0.80, 0.87) mean difference 5 μm (95% LOA -51.8, 61.8). Edge-detection measurements were greater than those from manual sonographic calipers (mean aIMT 618 μm (50) versus mean aIMT 563 μm (49) respectively; p < 0.001, mean difference 44 μm, 95% LOA -54, 142). With the exception of infant crying (p = 0.001), no associations were observed between individual and environmental variables and image quality. Conclusion: In a population-derived cohort of term infants, aIMT measurement has a high level of intra and inter-reader reproducibility. Measurement of aIMT using edge-detection software gives higher inter-reader ICC than manual sonographic calipers. Image quality is not substantially affected by individual and environmental factors. © 2014 McCloskey et al.; licensee BioMed Central Ltd

DNA species surveillance: Monitoring bushmeat poaching and trading in Kenya using partial cytochrome b gene

DNA species identification has applications in such areas as forensic science, systematics, conservation genetics and agriculture. One key anthropogenic activity threatening large wildlife fauna is illegal exploitation. In Kenya, species identification of raw and processed meat products remains a constraint to effective enforcement of illegal trade in game meat (bushmeat) and products. We tested the reliability of a 321 bp mitochondrial cytochrome b (cyt b) region as a species identification tool for application in wildlife forensics. Query sequences were generated from known specimens of 14 Eastern African wildlife species, 13 representing commonly poached ungulates, and three domesticated species. These were compared, using Basic Local Alignment Search Tool (BLAST) algorithm, with NCBI GenBank reference sequences for species identity. These query sequences were subsequently deposited on Genbank. They represent a contribution to a diagnostic internal East African Wildlife reference cyt b database. The test species comprised: Cape buffalo, bushbuck, Guenther’s dik-dik, common duiker, common eland, Grant’s gazelle, hartebeest, impala, lesser kudu, plains zebra, Thomson’s gazelle, common warthog, wildebeest, Maasai ostrich, cattle, goat and sheep. Additionally, cooked beef and pork samples were analyzed. The results show that, when conspecific sequences were available in the database, species discrimination was 100%. Phylogeny clustering of the species by maximum likelihood supported the species determination by BLAST. The second part of the study carried out a preliminary survey of the prevalence of illegal game meat sold in the dispersal area of Tsavo National Park, Kenya. Sixty two raw meat samples were randomly collected from small roadside retail outlets along the Nairobi-Mombasa highway (A109), a major transnational highway that transverses Tsavo National Park. The results indicate a 9.7% (n = 6) illegal game meat sale, comprising five Guenther’s dik-diks and a Beisa oryx. A 2 km radius hotspot, with 83% (n = 5) of the bushmeat sales was identified just south of Tsavo East National Park.Key words: East Africa, Kenya, bushmeat, poaching, wildlife conservation, species identification, mitochondrial cytochrome b gene
