Self-efficacy and academic listening
Abstract This paper takes as its starting point the difficulties inherent in listening in a second language. It argues that self-efficacy, broadly defined as the belief in one's ability to carry out specific tasks successfully, is crucial to the development of effective listening skills, and that listening strategy instruction has the potential to boost self-efficacy. The degree of control over the process of listening that learners can gain through listening strategy instruction is an important factor in this process. Reviewing studies that have integrated strategy instruction with measures to address learners' sense of control and self-efficacy for listening, it concludes by arguing that in an EAP context, such a heightened sense of confidence can help learners cope more effectively with authentic oral input
Collaborating and Co-operating to Make the Connection: How Law Librarians and Academics Can Work Together to Develop Communities of Legal Practice
The Library is of value as a physical and social space, as a place that can facilitate learning; independently and in distinct ways to its role as repository of, and point of access to, information. The problems that defenders of this "learning place" aspect of the Library face are bound up with a very powerful, and indeed prevalent, metaphor. This metaphor is of teaching and learning as the transfer of information from one place or
head, to another place or head. Therefore, Graham Ferris and Angela Donaldson put forward a far more realistic account of learning, and combine it with an example of
learning being enacted in practice. We need to articulate the value of the Library as a place of learning because it is under threat from pressures on resources that are being deployed on a "common sense" but fallacious assumption that Libraries are about the storage and manipulation of information only
Restrictive covenants in Xanadu
Legal scholarship is naturally inclined towards explanations and justifications of contemporary law. In the case of restrictive covenants and building schemes this has led to a distorted perception of the historical record, as revealed in recorded case reports dating from the nineteenth century. It is argued that the restrictive covenant had its historical genesis not in a response to industrialisation and mass urbanisation, but in the developments of resort towns in the eighteenth and early nineteenth centuries, as a response to the needs of land developers. Furthermore, it is argued that a better historical understanding of these origins illuminates contemporary problems concerned with the adaptability of law and the potential roles of law in development

Examination of the comfort and pain experienced with blood flow restriction training during post-surgery rehabilitation of anterior cruciate ligament reconstruction patients: A UK National Health Service trial.
Examine the comfort and pain experienced with blow flow restriction resistance training (BFR-RT) compared to standard care heavy load resistance training (HL-RT) during anterior cruciate ligament reconstruction (ACLR) patient rehabilitation. Randomised controlled trial. United Kingdom National Health Service. Twenty eight patients undergoing unilateral ACLR surgery with hamstring autograft were recruited. Following surgery participants were block randomised to either HL-RT at 70% repetition maximum (1RM) (n = 14) or BFR-RT (n = 14) at 30% 1RM and completed 8 weeks of twice weekly unilateral leg press training on both limbs. Perceived knee pain, muscle pain and rating of perceived exertion (RPE) were assessed using Borg's (1998) RPE and pain scales during training. Knee pain was also assessed 24 h post-training. There were no adverse events. Knee pain was lower with BFR-RT during (p 0.05) for both BFR-RT and HL-RT. ACLR patients experienced less knee joint pain and reported similar ratings of perceived exertion during and following leg press exercise with BFR-RT compared to traditional HL-RT. BFR-RT may be more advantageous during the early phases of post-surgery ACLR rehabilitation. [Abstract copyright: Copyright © 2019. Published by Elsevier Ltd.
Net generation or Digital Natives: Is there a distinct new generation entering university?
This article reports key findings from the first phase of a research project investigating Net generation age students as they encounter e-learning at five universities in England. We take a critical view of the idea of a distinct generation which has been described using various terms including Net generation and Digital Natives and explore age related differences amongst first year university students. The article draws on evidence from a survey of first year undergraduates studying a range of pure and applied subjects. Overall we found a complex picture amongst first-year students with the sample population appearing to be a collection of minorities. These included a small minority that made little use of some technologies and larger minorities that made extensive use of new technologies. Often the use of new technology was in ways that did not fully correspond with the expectations that arise from the Net generation and Digital Natives theses. The article concludes that whilst there are strong age related variations amongst the sample it is far to simplistic to describe young first-year students born after 1983 as a single generation. The authors find that the generation is not homogenous in its use and appreciation of new technologies and that there are significant variations amongst students that lie within the Net generation age band
Genetic Diversity in the Collaborative Cross Model Recapitulates Human West Nile Virus Disease Outcomes
ABSTRACTWest Nile virus (WNV) is an emerging neuroinvasive flavivirus that now causes significant morbidity and mortality worldwide. The innate and adaptive immune responses to WNV infection have been well studied in C57BL/6J inbred mice, but this model lacks the variations in susceptibility, immunity, and outcome to WNV infection that are observed in humans, thus limiting its usefulness to understand the mechanisms of WNV infection and immunity dynamics. To build a model of WNV infection that captures human infection outcomes, we have used the Collaborative Cross (CC) mouse model. We show that this model, which recapitulates the genetic diversity of the human population, demonstrates diversity in susceptibility and outcomes of WNV infection observed in humans. Using multiple F1 crosses of CC mice, we identified a wide range of susceptibilities to infection, as demonstrated through differences in survival, clinical disease score, viral titer, and innate and adaptive immune responses in both peripheral tissues and the central nervous system. Additionally, we examined the Oas1b alleles in the CC mice and confirmed the previous finding that Oas1b plays a role in susceptibility to WNV; however, even within a given Oas1b allele status, we identified a wide range of strain-specific WNV-associated phenotypes. These results confirmed that the CC model is effective for identifying a repertoire of host genes involved in WNV resistance and susceptibility. The CC effectively models a wide range of WNV clinical, virologic, and immune phenotypes, thus overcoming the limitations of the traditional C57BL/6J model, allowing genetic and mechanistic studies of WNV infection and immunity in differently susceptible populations.IMPORTANCEMouse models of West Nile virus infection have revealed important details regarding the innate and adaptive immune responses to this emerging viral infection. However, traditional mouse models lack the genetic diversity present in human populations and therefore limit our ability to study various disease outcomes and immunologic mechanisms subsequent to West Nile virus infection. In this study, we used the Collaborative Cross mouse model to more effectively model the wide range of clinical, virologic, and immune phenotypes present upon West Nile virus infection in humans

Processing of a Multiple Membrane Spanning Epstein-Barr Virus Protein for Cd8+T Cell Recognition Reveals a Proteasome-Dependent, Transporter Associated with Antigen Processing–Independent Pathway
Epstein-Barr virus (EBV) latent membrane protein (LMP)2 is a multiple membrane spanning molecule which lacks ectodomains projecting into the lumen of the endoplasmic reticulum (ER). Human CD8+ cytotoxic T lymphocytes (CTL)s recognize a number of epitopes within LMP2. Assays with epitope-specific CTLs in two different cell backgrounds lacking the transporter associated with antigen processing (TAP) consistently show that some, but not all, LMP2 epitopes are presented in a TAP-independent manner. However, unlike published examples of TAP-independent processing from endogenously expressed antigens, presentation of TAP-independent LMP2 epitopes was abrogated by inhibition of proteasomal activity. We found a clear correlation between hydrophobicity of the LMP2 epitope sequence and TAP independence, and experiments with vaccinia minigene constructs expressing cytosolic epitope peptides confirmed that these more hydrophobic peptides were selectively able to access the HLA class I pathway in TAP-negative cells. Furthermore, the TAP-independent phenotype of particular epitope sequences did not require membrane location of the source antigen since (i) TAP-independent LMP2 epitopes inserted into an EBV nuclear antigen and (ii) hydrophobic epitope sequences native to EBV nuclear antigens were both presented in TAP-negative cells. We infer that there is a proteasome-dependent, TAP-independent pathway of antigen presentation which hydrophobic epitopes can selectively access
