Assessing Chinese Consumers Likelihood To Adopt Self-Service Technologies
The proliferation of new self-service technology in retailing suggests a need to assess the extent to which consumers are ready and willing to actually use the technology. This study examines the influence that the dimensions of the Technology Readiness Index (TRI) has on the propensity of consumers in China, one of the fastest growing economies in the world, to use self-service technology to complete retail transactions. Cluster analysis was also used to classify Chinese consumers into consumer types based on their TRI scores. The findings indicate that the dimensions of TRI impacts consumer types differently with respect to influencing the likelihood of using self-service technology. Implications of the consumer classifications are also discussed

Student Technology Readiness And Its Impact On Cultural Competency
The creation of an effective learning environment requires cultural competency – the ability to interact effectively with people of different cultures. Cultural competency means knowing and understanding the people that you serve. This study compares American and Chinese student’s readiness and willingness to use innovative technology by assessing their technology readiness through the use of the Technology Readiness Index (Parasuraman, 2000). The findings show that Chinese students exhibit higher levels of discomfort and insecurity, and lower levels of optimism and innovativeness with regard to using new technology. Implications for cross-cultural technology-based learning environments are also provided

Electrical properties of Bi-implanted amorphous chalcogenide films
The impact of Bi implantation on the conductivity and the thermopower of
amorphous chalcogenide films is investigated. Incorporation of Bi in Ge-Sb-Te
and GeTe results in enhanced conductivity. The negative Seebeck coefficient
confirms onset of the electron conductivity in GeTe implanted with Bi at a dose
of 2x1016 cm-2. The enhanced conductivity is accompanied by defect accumulation
in the films upon implantation as is inferred by using analysis of the
space-charge limited current. The results indicate that native coordination
defects in lone-pair semiconductors can be deactivated by means of ion
implantation, and higher conductivity of the films stems from additional
electrically active defects created by implantation of bismuth.Comment: This is an extended version of the results presented in Proc. SPIE

Multidimensional collaboration; reflections on action research in a clinical context
This paper reflects on the challenges and benefits of multidimensional collaboration in an action research study to evaluate and improve preoperative education for patients awaiting colorectal surgery. Three cycles of planning, acting,observing and reflecting were designed to evaluate practice and implement change in this interactive setting, calling for specific and distinct collaborations. Data collection includes: observing educational interactions; administering patient evaluation questionnaires; interviewing healthcare staff, patients and carers; patient and carer focus groups; and examining written and audiovisual educational materials. The study revolves around and depends on multi-dimensional collaborations. Reflecting on these collaborations highlights the diversity of perspectives held by all those engaged in the study and enhances the action research lessons. Successfully maintaining the collaborations recognises the need for negotiation, inclusivity, comprehension, brokerage,and problem-solving. Managing the potential tensions is crucial to the successful implementation of changes introduced to practice and thus has important implications for patients’ well-being. This paper describes the experiences from an action research project involving new and specific collaborations, focusing on a particular healthcare setting. It exemplifies the challenges of the collaborative action research process and examines how both researchers and practitioners might reflect on the translation of theory into educational practices within a hospital colorectal department. Despite its context-specific features, the reflections on the types of challenges faced and lessons learned provide implications for action researchers in diverse healthcare settings across the world
Geographic Variation in Pneumonia and Influenza in Long-Term Care Facilities:A National Study
There is large county-level geographic variation in pneumonia and influenza hospitalizations among short-stay and long-stay long-term care facility residents in the United States. Long-term care facilities in counties in the Southern and Midwestern regions had the highest rates of pneumonia and influenza from 2013 to 2015. Future research should identify reasons for these geographic differences

How important are post-tropical cyclones for European windstorm risk?
Post-tropical cyclones (PTCs) extend many hazards associated with tropical cyclones (TCs) to the mid-latitudes. Despite recent high-impact cases affecting Europe such as Ophelia, little research has been done to characterize the risk of PTCs. Here we compare the climatologies and intensity distributions of mid-latitude cyclones (MLCs) and PTCs in the North Atlantic and Europe by tracking cyclones in the ERA5 reanalysis. Considering hurricane-season cyclones impacting Northern Europe, PTCs show a significantly higher mean maximum intensity than MLCs, but make only a small contribution to total windstorm risk. Our results show that a disproportionately large fraction of high-intensity cyclones impacting Europe during hurricane season are PTCs. The fraction of PTCs impacting N Europe with storm-force (>25ms-1) winds is approximately ten times higher than for MLCs. Less than 1% of cyclones impacting Northern Europe are identified to be PTCs. This rises to 8.8% when considering cyclones which impact with storm-force winds
Limited antigenic diversity of Plasmodium falciparum apical membrane antigen 1 supports the development of effective multi-allele vaccines
BackgroundPolymorphism in antigens is a common mechanism for immune evasion used by many important pathogens, and presents major challenges in vaccine development. In malaria, many key immune targets and vaccine candidates show substantial polymorphism. However, knowledge on antigenic diversity of key antigens, the impact of polymorphism on potential vaccine escape, and how sequence polymorphism relates to antigenic differences is very limited, yet crucial for vaccine development. Plasmodium falciparum apical membrane antigen 1 (AMA1) is an important target of naturally-acquired antibodies in malaria immunity and a leading vaccine candidate. However, AMA1 has extensive allelic diversity with more than 60 polymorphic amino acid residues and more than 200 haplotypes in a single population. Therefore, AMA1 serves as an excellent model to assess antigenic diversity in malaria vaccine antigens and the feasibility of multi-allele vaccine approaches. While most previous research has focused on sequence diversity and antibody responses in laboratory animals, little has been done on the cross-reactivity of human antibodies.MethodsWe aimed to determine the extent of antigenic diversity of AMA1, defined by reactivity with human antibodies, and to aid the identification of specific alleles for potential inclusion in a multi-allele vaccine. We developed an approach using a multiple-antigen-competition enzyme-linked immunosorbent assay (ELISA) to examine cross-reactivity of naturally-acquired antibodies in Papua New Guinea and Kenya, and related this to differences in AMA1 sequence.ResultsWe found that adults had greater cross-reactivity of antibodies than children, although the patterns of cross-reactivity to alleles were the same. Patterns of antibody cross-reactivity were very similar between populations (Papua New Guinea and Kenya), and over time. Further, our results show that antigenic diversity of AMA1 alleles is surprisingly restricted, despite extensive sequence polymorphism. Our findings suggest that a combination of three different alleles, if selected appropriately, may be sufficient to cover the majority of antigenic diversity in polymorphic AMA1 antigens. Antigenic properties were not strongly related to existing haplotype groupings based on sequence analysis.ConclusionsAntigenic diversity of AMA1 is limited and a vaccine including a small number of alleles might be sufficient for coverage against naturally-circulating strains, supporting a multi-allele approach for developing polymorphic antigens as malaria vaccines
