Social media ‘on the go’: Examining the impact of age

Social media can, therefore, be seen as an extension of people’s lives with opportunities to construct virtual identities as well as personal, social and professional spaces that altogether extend boundaries of offline contexts. Social media consumption is particularly immersive and complex in the cases when individuals are accessing and using social media on the go, via mobile devices. Although extensive number of studies explored the consumers’ adoption of mobile technology and adoption of social media, adoption of mobile social media (consumption of social media on mobile devices) remains underexplored. Moreover, existing research on social media adoption has identified two generational groups, generation Y (aged 18-25) and generation X (aged 35-60) which have active use of social media, although their motives and attitudes towards social media as well as consumption patterns differ. With the increased use of social media ‘on the go’, no existing studies have investigated the generational gap in the adoption and use of mobile social media (MSM). Hence, this work-in-progress paper aims to address identified research gaps by proposing and justifying conceptual model to be examined via mixed research method

Using Peerwise to improve engagement and learning.

This paper assesses the experiences of Bournemouth University in using the online multiple choice question (MCQ) tool, Peerwise, in student learning and engagement. MCQs are excellent for developing and testing knowledge, providing reassurance and identifying development needs. The creation of MCQs reinforces learning by tasking students to generate challenging questions. Peerwise supports self-direction and flexibility, which is embraced by students. Bournemouth University started embedding Peerwise within teaching units in 2014. The intention was to transform the approach of students towards the non-assessed elements of the unit. Peerwise was used in an undergraduate business unit consisting of 50 students over at 15 week period. 804 questions were created and 3,345 answers were recorded. 10% of the unit marks were allocated to Peerwise use. Qualitative feedback from students was very positive. Correlation analysis showed a very weak relationship, 0.120, between the number of questions answered and the overall unit mark. Self-assessment of the change in learning was statistically significantly better for students who used Peerwise compared to those who did not. Overall, the evaluation of the Peerwise was positive with many lessons learnt. Six recommendations for the further use of Peerwise were developed, including improving the scaffolding to students, refining the way quality is assessed and developing evaluation criteria

Radicalising the marketing of higher education: learning from student-generated social media data

The social media landscape creates opportunities for higher education institutions (HEIs) to amplify psychological engagement with students and to increase influence impressions by following student(s)-to-student(s) conversations and stories. Evidence of understanding how HEIs can utilise student-generated social media data for HE marketing and branding purposes is underexplored. This paper adopts a netnographic research method to illustrate how social media artefacts, such as the ‘This Is Where I Study’ (TIWIS) Facebook page, created by students in the form of dialogues and content, can be analysed by HEIs to listen, engage further and influence students’ impressions. TIWIS illustrates that students’ engagement with social media platforms such as Facebook is dynamic in nature. It comprises behavioural expressions (manifestations and actions such as likes and shares as well opinion comments) and individuals’ experiences (subjective in nature stories and comments of personal experiences and views). Hence, netnographic analysis allows capturing actual behaviours via longitudinal ‘big data’ sets and support HEIs in proactive branding. Analysis of social media data demonstrates the value of encouraging and making accessible authentic conversations in order to create student-centred content

Enhancing university student engagement using online multiple choice questions and answers

For many education providers, student engagement can be a major issue. Given the positive correlation between engagement and good performance, providers are continually looking for ways to engage students in the learning process. The growth of student digital literacy, the wide proliferation of online tools and the understanding of why online gaming can be addictive have combined to create a set of tools that providers can leverage to enhance engagement. One such tool is Peerwise, https://peerwise.cs.auckland.ac.nz/, an online, multiple choice question (MCQ) and answer tool in which students create questions that are answered by other students. Why use MCQs? Using MCQs tests knowledge, provides reassurance of learning, identifies gaps and makes this data available to student and provider. Students use this information to focus their time on areas requiring additional work [1], benefiting from the early feedback provided. Formative assess- ments using MCQs are beneficial in preparing students for summative testing and are appreciated and liked by students [2]. Providers can use this information to determine how the material is being received and react accordingly. Students use Peerwise to create MCQs that are answered, rated and commented on by their peers. Students’ engagement in Peerwise earns trophies for contributing regular use and for providing feedback, all of which act to stimulate further engagement, using the principles of gamification. Bournemouth University, a public university in the UK with over 18,000 students, has been embedding Peerwise in under-graduate and post-graduate units since 2014. The results experienced by Bournemouth University have been beneficial and correlate with other studies of using Peerwise [3] [4]. A statistically significant improvement was seen by one cohort of students compared to the previous year where Peerwise was not used. However, no correlation was found between Peerwise participation and a student’s unit mark. The processes followed by Bournemouth University and the advantages and disadvantages, backed by qualitative and quantitative data, will be presented so that other institutions can gain an informed view of the merits of Peerwise for their own teaching and learning environments

Choroidal metastases in testicular choriocarcinoma, successful treatment with chemo- and radiotherapy: a case report

<p>Abstract</p> <p>Background</p> <p>Choriocarcinoma is a very rare cause of ocular metastasis. Only 18 male patients have been reported on, 4 of whom survived, but with significant loss of vision.</p> <p>Case presentation</p> <p>A 26-year-old Caucasian man, suffering from testicular choriocarcinoma with pulmonary, cerebral, renal, hepatic and osseous metastases, underwent left radical orchiectomy. While being treated with chemotherapy, he presented with loss of vision in the left eye. Ophthalmoscopy revealed bilateral non-pigmented, hemorrhagic choroidal tumours, compatible with secondary lesions. Continued chemotherapy and stereotactic radiotherapy of the skull and spine lead to full remission with excellent vision, after more than 4 years of follow up.</p> <p>Conclusion</p> <p>Testicular choriocarcinoma is an exceptional cause of choroidal metastasis, potentially asymptomatic and with specific clinical features. Radiotherapy can complement radical orchiectomy and chemotherapy, to achieve full remission and maintain good vision.</p

Terahertz Bandpass Frequency Selective Surfaces on Glass Substrates Using a Wet Micromachining Process

This paper presents terahertz (THz) frequency selective surfaces (FSS) implemented on glass substrate using standard microfabrication techniques. These FSS structures are designed for frequencies around 0.8 THz. A fabrication process is proposed where a 100-μm-thick glass substrate is formed through the HF etching of a standard 500-μm-thick low cost glass wafer. Using this fabrication process, three separate robust designs consisting of single-layer FSS are investigated using high-frequency structural simulator (HFSS). Based on the simulation results, the first design consists of a circular ring slot in a square metallic structure on top of a 100-μm-thick Pyrex glass substrate with 70% transmission bandwidth of approximately 0.07 THz, which remains nearly constant till 30° angle of incidence. The second design consists of a tripole structure on top of a 100-μm-thick Pyrex glass substrate with 65% transmission bandwidth of 0.035 THz, which remains nearly constant till 30° angle of incidence. The third structure consists of a triangular ring slot in a square metal on top of a 100-μm-thick Pyrex glass substrate with 70% transmission bandwidth of 0.051 THz, which remains nearly constant up to 20° angle of incidence. These designs show that the reflections from samples can be reduced compared to the conventional sample holders used in THz spectroscopy applications, by using single layer FSS structures manufactured through a relatively simple fabrication process. Practically, these structures are achieved on a fabricated 285-μm-thick glass substrate. Taking into account the losses and discrepancies in the substrate thickness, the measured results are in good agreement with the electromagnetic simulations. © 2017, Springer Science+Business Media New York

A microsatellite marker for yellow rust resistance in wheat

Bulk segregant analysis (BSA) was used to identify molecular markers associated with yellow rust disease resistance in wheat (Triticum aestivum L.). DNAs isolated from the selected yellow rust tolerant and susceptible F-2 individuals derived from a cross between yellow rust resistant and susceptible wheat genotypes were used to established a "tolerant" and a "susceptible" DNA pool. The BSA was then performed on these DNA pools using 230 markers that were previously mapped onto the individual wheat chromosomes. One of the SSR markers (Xgwm382) located on chromosome group 2 (A, B, D genomes) was present in the resistant parent and the resistant bulk but not in the susceptible parent and the susceptible bulk, suggesting that this marker is linked to a yellow rust resistance gene. The presence of Xgwm382 was also tested in 108 additional wheat genotypes differing in yellow rust resistance. This analysis showed that 81% of the wheat genotypes known to be yellow rust resistant had the Xgwm382 marker, further suggesting that the presence of this marker correlates with yellow rust resistance in diverse wheat germplasm. Therefore, Xgwm382 could be useful for marker assisted selection of yellow rust resistances genotypes in wheat breeding programs
