Implementing the Critical Friend Method for Peer Feedback among Teaching Librarians in an Academic Setting

Objective – The role of the academic librarian has become increasingly educative in nature. In this study, the critical friend method was introduced among teaching librarians in an academic setting of medicine and health sciences to ascertain whether this approach could be implemented for feedback on teaching of these librarians as part of their professional development. Methods – We used a single intrinsic case study. Seven teaching librarians and one educator from the faculty of medicine participated, and they all provided and received feedback. These eight teachers worked in pairs, and each of them gave at least one lecture or seminar during the study period. The performance of one teacher and the associated classroom activities were observed by the critical friend and then evaluated and discussed. The outcome and effects of critical friendship were assessed by use of a questionnaire. Results – The present results suggest that use of the critical friend method among teaching academic librarians can have a positive impact by achieving the following: strengthening shared values concerning teaching issues; promoting self-reflection, which can improve teaching; facilitating communication with colleagues; and reducing the sense of “loneliness” in teaching. This conclusion is also supported by the findings of previous studies. Conclusion – The critical friend method described in this study can easily be implemented and developed among teaching librarians, provided that there is support from the organization. This will benefit the individual teaching librarian, as well as the organization at large

Inferring Processes of Coevolutionary Diversification in a Community of Panamanian Strangler Figs and Associated Pollinating Wasps

The fig and pollinator wasp obligate mutualism is diverse (~750 described species), ecologically important, and ancient (~80-90 Ma), providing model systems for generating and testing many questions in evolution and ecology. Once thought to be a prime example of strict one-to-one cospeciation, current thinking suggests that genera of pollinator wasps coevolve with corresponding subsections of figs, but the degree to which cospeciation or other processes contributes to the association at finer scales is unclear. Here we use genome-wide sequence data from a community of Panamanian strangler figs (Ficus subgenus Urostigma, section Americana) and associated fig wasp pollinators (Pegoscapus spp.) to infer the process of coevolutionary diversification in this obligate mutualism. Using a model-based approach adapted from the study of gene family evolution, our results indicate pervasive and ongoing host switching of pollinator wasps at this fine phylogenetic and regional scale. Although the model estimates a modest amount of cospeciation, simulations reveal this signal to be consistent with levels of co-association expected under a model of free host switching. Our findings provide an outline for testing how ecological and evolutionary processes can be modeled to evaluate the history of association of interacting lineages in a phylogenetic framework

A Test of Evolutionary Policing Theory with Data from Human Societies

In social groups where relatedness among interacting individuals is low, cooperation can often only be maintained through mechanisms that repress competition among group members. Repression-of-competition mechanisms, such as policing and punishment, seem to be of particular importance in human societies, where cooperative interactions often occur among unrelated individuals. In line with this view, economic games have shown that the ability to punish defectors enforces cooperation among humans. Here, I examine a real-world example of a repression-of-competition system, the police institutions common to modern human societies. Specifically, I test evolutionary policing theory by comparing data on policing effort, per capita crime rate, and similarity (used as a proxy for genetic relatedness) among citizens across the 26 cantons of Switzerland. This comparison revealed full support for all three predictions of evolutionary policing theory. First, when controlling for policing efforts, crime rate correlated negatively with the similarity among citizens. This is in line with the prediction that high similarity results in higher levels of cooperative self-restraint (i.e. lower crime rates) because it aligns the interests of individuals. Second, policing effort correlated negatively with the similarity among citizens, supporting the prediction that more policing is required to enforce cooperation in low-similarity societies, where individuals' interests diverge most. Third, increased policing efforts were associated with reductions in crime rates, indicating that policing indeed enforces cooperation. These analyses strongly indicate that humans respond to cues of their social environment and adjust cheating and policing behaviour as predicted by evolutionary policing theory

An extreme case of plant-insect co-diversification: figs and fig-pollinating wasps

It is thought that speciation in phytophagous insects is often due to colonization of novel host plants, because radiations of plant and insect lineages are typically asynchronous. Recent phylogenetic comparisons have supported this model of diversification for both insect herbivores and specialized pollinators. An exceptional case where contemporaneous plant insect diversification might be expected is the obligate mutualism between fig trees (Ficus species, Moraceae) and their pollinating wasps (Agaonidae, Hymenoptera). The ubiquity and ecological significance of this mutualism in tropical and subtropical ecosystems has long intrigued biologists, but the systematic challenge posed by >750 interacting species pairs has hindered progress toward understanding its evolutionary history. In particular, taxon sampling and analytical tools have been insufficient for large-scale co-phylogenetic analyses. Here, we sampled nearly 200 interacting pairs of fig and wasp species from across the globe. Two supermatrices were assembled: on average, wasps had sequences from 77% of six genes (5.6kb), figs had sequences from 60% of five genes (5.5 kb), and overall 850 new DNA sequences were generated for this study. We also developed a new analytical tool, Jane 2, for event-based phylogenetic reconciliation analysis of very large data sets. Separate Bayesian phylogenetic analyses for figs and fig wasps under relaxed molecular clock assumptions indicate Cretaceous diversification of crown groups and contemporaneous divergence for nearly half of all fig and pollinator lineages. Event-based co-phylogenetic analyses further support the co-diversification hypothesis. Biogeographic analyses indicate that the presentday distribution of fig and pollinator lineages is consistent with an Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance. Overall, our findings indicate that the fig-pollinator mutualism represents an extreme case among plant-insect interactions of coordinated dispersal and long-term co-diversification

Social Media, Insta-Culture and The Reinvention of Fashion Week

Background: It is clear that the fashion industry is experiencing a change as a result of the explosion of social media. Today the four key social media platforms for fashion houses are Instagram, Facebook, Twitter and Snapchat. The society has created a culture around these media platforms, which is referred to as insta-culture. Why read Vogue magazine to find out the latest trends, when social media is covering the runways in real time? A debate about what direction the fashion industry is heading towards is a hot topic of discussion. The fashion industry has gone through changes before but now consumers have become more demanding regarding quick accessibility of fashion. Consumer behavior and the way we consume fashion has changed. An obvious sign of the change within the industry is how fashion weeks around the world have become the most coveted”it” event for celebrities and fashionistas worldwide. Fashion week is a fashion industry event that lasts around one week. The goal is for the fashion industry to network and for fashion houses to share their next season collections. Fashion weeks have traditionally been a closed, trade only-event which highlights promotional and glamorous entertainment events. However, now it is the most important shows that everyone wants to be seen at. What will become of fashion weeks is truly unknown. One thing that is for sure is that the development of social media definitely plays a vital role in the change of the industry. Aims of the research: The broader aim of this research is to analyze through the lens of fashion week, what is happening in fashion week and the driver of change within the fashion industry, social media, and to unravel why we see a change in fashion week now. The second aim is also to investigate in what way the change is affecting the way fashion is displayed at fashion weeks. Methods: This thesis was completed by gathering observations and analyzing interviews, blogs, press, journal articles, social media and observations that focused on the phenomenon of fashion week especially in the New York and Stockholm context. This qualitative method is referring to as Netnography using primarily data gathering from the internet and data from the existing interviews with people from the industry. Results: Social media has affected the fashion weeks in many ways. Today fashion brands have to include social media in their marketing strategy in order to survive in the insta-culture that reflects on the society. The insta-culture has as well resulted in that fashion week has been reinvented to an entertainment event open for everyone. The democratization of the fashion week has in turn resulted in that designers have to change how and when they deliver fashion. Instead of waiting six months for the collections to hit the stores, designers now have adopted a see now buy now model. Contributions: The result of this thesis brings awareness to people within the fashion industry and fashion theories when it comes to what is happening to the industry and how to better support fashion management strategies. Social media has created an insta-culture in the society that also affects the fashion industry. This thesis also highlights the great impact that the society has on fashion even today. This study therefore further develops the sociological theory when it comes to the impact from the society and how it affects fashion
