Actively Engaging with Patrons on Social Media

Using social media for outreach entails more than just creating engaging content— it also means actively engaging with patrons. In our experience, using social media well involves a heavy emphasis on two-way communication with patrons. We have built a social media presence that, above all, seeks to build relationships with our patrons. It provides a venue for building relationships with both those who already closely associate with the library and those who do not. Establishing and strengthening ties to the library makes patrons more likely to share their positive perceptions of us with friends, family, colleagues, and coworkers. Because word-ofmouth remains the most credible mode of advertising (Nielsen, 2015), social media has the potential to greatly enhance the image of the library. This chapter lays out the strategies we have found most successful in building relationships with patrons via social media and will help librarians take advantage of it as a tool for two-way interaction by providing best practices for engaging with patrons. Our strategies revolve around listening to and seeking opportunities to engage with patrons and assessing the appropriate mode of interaction

Major role of iron uptake systems in the intrinsic extra-intestinal virulence of the genus Escherichia revealed by a genome-wide association study

The genus Escherichia is composed of several species and cryptic clades, including E. coli, which behaves as a vertebrate gut commensal, but also as an opportunistic pathogen involved in both diarrheic and extra-intestinal diseases. To characterize the genetic determinants of extra-intestinal virulence within the genus, we carried out an unbiased genome-wide association study (GWAS) on 370 commensal, pathogenic and environmental strains representative of the Escherichia genus phylogenetic diversity and including E. albertii (n = 7), E. fergusonii (n = 5), Escherichia clades (n = 32) and E. coli (n = 326), tested in a mouse model of sepsis. We found that the presence of the high-pathogenicity island (HPI), a similar to 35 kbp gene island encoding the yersiniabactin siderophore, is highly associated with death in mice, surpassing other associated genetic factors also related to iron uptake, such as the aerobactin and the sitABCD operons. We confirmed the association in vivo by deleting key genes of the HPI in E. coli strains in two phylogenetic backgrounds. We then searched for correlations between virulence, iron capture systems and in vitro growth in a subset of E. coli strains (N = 186) previously phenotyped across growth conditions, including antibiotics and other chemical and physical stressors. We found that virulence and iron capture systems are positively correlated with growth in the presence of numerous antibiotics, probably due to co-selection of virulence and resistance. We also found negative correlations between virulence, iron uptake systems and growth in the presence of specific antibiotics (i.e. cefsulodin and tobramycin), which hints at potential "collateral sensitivities" associated with intrinsic virulence. This study points to the major role of iron capture systems in the extra-intestinal virulence of the genus Escherichia. Author summary Bacterial isolates belonging to the genus Escherichia can be human commensals but also opportunistic pathogens, with the ability to cause extra-intestinal infection. There is therefore the need to identify the genetic elements that favour extra-intestinal virulence, so that virulent bacterial isolates can be identified through genome analysis and potential treatment strategies be developed. To reduce the influence of host variability on virulence, we have used a mouse model of sepsis to characterize the virulence of 370 strains belonging to the genus Escherichia, for which whole genome sequences were also available. We have used a statistical approach called Genome-Wide Association Study (GWAS) to show how the presence of genes that encode for iron scavenging are significantly associated with the propensity of a bacterial isolate to cause extra-intestinal infections. Taking advantage of previously generated growth data on a subset of the strains and its correlation to virulence we generated hypothesis on the relationship between iron scavenging and growth in the presence of various antimicrobials, which could have implications for developing new treatment strategies

On Drugs

Despite their centrality to medicine, drugs are not easily defined. We introduce two desiderata for a basic definition of medical drugs. It should: (i) capture everything considered to be a drug in medical contexts and (ii) rule out anything that is not considered to be a drug. After canvassing a range of options, we find that no single definition of drugs can satisfy both desiderata. We conclude with three responses to our exploration of the drug concept: maintain a monistic concept, or choose one of two pluralistic outcomes. Notably, the distinction between drugs and other substances is placed under pressure by the most plausible of the options available

The effects of autistic traits and academic degree on visuospatial abilities.

In the present study, we were interested to investigate how autistic traits (including systemizing and empathy) and academic degree influence individuals' visuospatial abilities. To this end, 352 university students completed the Autism Spectrum Quotient (AQ), the Empathy Quotient, the Systemizing Quotient (SQ) and visuospatial tests measuring figure disembedding and mental rotation of two-dimensional figures. Engineering-design students (architecture and engineering) were the most accurate in disembedding and mentally rotating figures, followed by students of physical sciences (computer science, chemistry, physics, etc.) and fact-based humanities (languages, classics, law); biological (psychology and neuroscience, etc.) and systems-based social scientists (economics and commerce) were the least accurate. Engineering-design students also showed higher SQ scores with respect to the other four academic degree subjects, with students of biological sciences showing lower SQ scores. Importantly, results from a path analysis revealed that SQ (but not AQ) exerted an indirect effect on figure disembedding and mental rotations through the influence of the academic degree. Thus, the present findings reveal shady differences in systemizing degree and visuospatial performance within systemizing-based degree subjects. Implications for education are discussed

The effect of autistic traits on disembedding and mental rotation in neurotypical women and men.

Recent data has revealed dissociations between social and non-social skills in both autistic and neurotypical populations. In the present study, we investigated whether specific visuospatial abilities, such as figure disembedding and mental rotation, are differently related to social and non-social autistic traits, in neurotypical women and men. University students (N = 426) completed the Autism Spectrum Quotient (AQ), figure disembedding and mental rotation of two-dimensional figures tasks. AQ social skills (AQ-social) and attention-to-details (AQ-attention) subscales were used as measures of social and non-social autistic traits, respectively. Mental rotation was affected by a significant interaction between sex, social and non-social traits. When non-social traits were above the mean (+ 1 SD), no sex differences in mental rotation were found. Instead, below this value, sex differences depended on the social traits, with men on average outperforming women at middle-to-high social traits, and with a comparable performance, and with women on average outperforming men, at lower social traits. A small positive correlation between figure disembedding and social traits was observed in the overall sample. These results are interpreted in terms of the hyper-systemizing theory of autism and contribute to the evidence of individual differences in the cognitive style of autistic people and neurotypical people with autistic traits

In hepatocellular carcinoma miR-221 modulates sorafenib resistance through inhibition of caspase-3\u2013mediated apoptosis

Purpose: The aberrant expression of miR-221 is a hallmark of human cancers, including hepatocellular carcinoma (HCC), and its involvement in drug resistance, together with a proved in vivo efficacy of anti-miR-221 molecules, strengthen its role as an attractive target candidate in the oncologic field. The discovery of biomarkers predicting the response to treatments represents a clinical challenge in the personalized treatment era. This study aimed to investigate the possible role of miR-221 as a circulating biomarker in HCC patients undergoing sorafenib treatment as well as to evaluate its contribution to sorafenib resistance in advanced HCC. Experimental Design: A chemically induced HCC rat model and a xenograft mouse model, together with HCC-derived cell lines were employed to analyze miR-221 modulation by Sorafenib treatment. Data from the functional analysis were validated in tissue samples from surgically resected HCCs. The variation of circulating miR-221 levels in relation to Sorafenib treatment were assayed in the animal models and in two independent cohorts of patients with advanced HCC. Results: MiR-221 over-expression was associated with Sorafenib resistance in two HCC animal models and caspase-3 was identified as its target gene, driving miR-221 anti-apoptotic activity following Sorafenib administration. Lower pre-treatment miR-221 serum levels were found in patients subsequently experiencing response to Sorafenib and an increase of circulating miR-221 at the two months assessment was observed in responder patients. Conclusions: MiR-221 might represent a candidate biomarker of likelihood of response to Sorafenib in HCC patients to be tested in future studies. Caspase-3 modulation by miR-221 participates to Sorafenib resistance

Trading Justice for Peace? Reframing reconciliation in TRC processes in South Africa, Canada and Nordic countries

Conflict in its various manifestations continues to be a defining feature in many places throughout the world. In an attempt to address such conflict, various forms of a Truth and Reconciliation Commission (TRC) have been introduced to facilitate the transition from social conflict to a new dispensation. The introduction and subsequent proceedings of TRCs in South Africa, Canada and Norway are widely regarded as good examples of this approach. Against this background, a number of researchers from VID Specialized University and the University of the Western Cape had an exploratory meeting in Oslo in 2018 where the possibility for a joint research project under the broad theme of ‘discourses on reconciliation’ was first discussed. This led to two further research symposia in Cape Town and Tromsø in 2019. With the inclusion of specialists working on the Canadian Truth and Reconciliation process, these meetings demonstrated common ground and a shared understanding of the issues at stake. Moreover, it pointed to the differences between the South African, Canadian and Norwegian Commissions. In comparing the South African, Canadian and Norwegian experiences, researchers identified that these countries were, in fact, at different stages of their respective truth and reconciliation processes. This has prompted scholars to revisit and problematise these processes in relation to ongoing societal challenges. In all cases, it is quite apparent that reconciliation between individuals and groups remains a significant challenge

Improving the quality and content of midwives’ discussions with low-risk women about their options for place of birth: Co-production and evaluation of an intervention package

Objective: Women's planned place of birth is gaining increasing importance in the UK, however evidence suggests that there is variation in the content of community midwives’ discussions with low risk women about their place of birth options. The objective of this study was to develop an intervention to improve the quality and content of place of birth discussions between midwives and low-risk women and to evaluate this intervention in practice. Design: The study design comprised of three stages: (1) The first stage included focus groups with midwives to explore the barriers to carrying out place of birth discussions with women. (2) In the second stage, COM-B theory provided a structure for co-produced intervention development with midwives and women representatives; priority areas for change were agreed and the components of an intervention package to standardise the quality of these discussions were decided. (3) The third stage of the study adopted a mixed methods approach including questionnaires, focus groups and interviews with midwives to evaluate the implementation of the co-produced package in practice. Setting: A maternity NHS Trust in the West Midlands, UK. Participants: A total of 38 midwives took part in the first stage of the study. Intervention design (stage 2) included 58 midwives, and the evaluation (stage 3) involved 66 midwives. Four women were involved in the intervention design stage of the study in a Patient and Public Involvement role (not formally consented as participants). Findings: In the first study stage participants agreed that pragmatic, standardised information on the safety, intervention and transfer rates for each birth setting (obstetric unit, midwifery-led unit, home) was required. In the second stage of the study, co-production between researchers, women and midwives resulted in an intervention package designed to support the implementation of these changes and included an update session for midwives, a script, a leaflet, and ongoing support through a named lead midwife and regular team meetings. Evaluation of this package in practice revealed that midwives’ knowledge and confidence regarding place of birth substantially improved after the initial update session and was sustained three months post-implementation. Midwives viewed the resources as useful in prompting discussions and aiding communication about place of birth options. Key conclusions and implications for practice: Co-production enabled development of a pragmatic intervention to improve the quality of midwives’ place of birth discussions with low-risk women, supported by COM-B theory. These findings highlight the importance of co-production in intervention development and suggest that the place of birth package could be used to improve place of birth discussions to facilitate informed choice at other Trusts across the UK
