Undergraduate search strategies and evaluation criteria: searching for credible sources

Purpose – The purpose of this paper is to determine undergraduate students’ information seeking behavior and their thought processes involved in, criteria applied to, and methods of evaluating the results of their searches, in determining which information to apply to their research. Design/methodology/approach – The authors observed, recorded and analyzed the processes and sources used by undergraduate students when seeking information on a given topic. Findings – Students did not use as many of the criteria necessary for evaluating sources for a research paper as the authors had hoped to observe; therefore, the students identified relatively few scholarly sources. Practical implications – Even though many of the students had had a course-integrated library instruction session before participating in the study, it did not seem to increase their evaluative skills, leading the authors to think that research skills need to be integrated in the curriculum in more meaningful ways by teaching faculty. Originality/value – The paper raises awareness of the search strategies and criteria that undergraduate students use to find information for their research papers

Reference E-Books: The Other Hidden Collection

This presentation was given at the 2010 Brick and Click Libraries Symposium at Northwest Missouri State University, Maryville, Missouri, November 5, 2010Traditional print reference collections have been reduced significantly over the past few years, as the preference for and the availability of electronic resources have increased. Librarians at the University of Kansas are concerned that the growing numbers of reference e-books in the collection are underutilized. There is a clear need to promote these resources to both library reference staff and users who are unaware of the numerous reference titles purchased individually or contained in electronic packages, such as Credo Reference. Although records for individual titles, from online reference collections and those purchased separately, are loaded into the online catalog, there is currently no easy way to browse the electronic reference collection

Recommendations for a national agenda to substantially reduce cervical cancer

PURPOSE: Prophylactic human papillomavirus (HPV) vaccines and new HPV screening tests, combined with traditional Pap test screening, provide an unprecedented opportunity to greatly reduce cervical cancer in the USA. Despite these advances, thousands of women continue to be diagnosed with and die of this highly preventable disease each year. This paper describes the initiatives and recommendations of national cervical cancer experts toward preventing and possibly eliminating this disease. METHODS: In May 2011, Cervical Cancer-Free America, a national initiative, convened a cervical cancer summit in Washington, DC. Over 120 experts from the public and private sector met to develop a national agenda for reducing cervical cancer morbidity and mortality in the USA. RESULTS: Summit participants evaluated four broad challenges to reducing cervical cancer: (1) low use of HPV vaccines, (2) low use of cervical cancer screening, (3) screening errors, and (4) lack of continuity of care for women diagnosed with cervical cancer. The summit offered 12 concrete recommendations to guide future national and local efforts toward this goal. CONCLUSIONS: Cervical cancer incidence and mortality can be greatly reduced by better deploying existing methods and systems. The challenge lies in ensuring that the array of available prevention options are accessible and utilized by all age-appropriate women-particularly minority and underserved women who are disproportionately affected by this disease. The consensus was that cervical cancer can be greatly reduced and that prevention efforts can lead the way towards a dramatic reduction in this preventable disease in our country

Interpretable Contextual Team-aware Item Recommendation: Application in Multiplayer Online Battle Arena Games

The video game industry has adopted recommendation systems to boost users interest with a focus on game sales. Other exciting applications within video games are those that help the player make decisions that would maximize their playing experience, which is a desirable feature in real-time strategy video games such as Multiplayer Online Battle Arena (MOBA) like as DotA and LoL. Among these tasks, the recommendation of items is challenging, given both the contextual nature of the game and how it exposes the dependence on the formation of each team. Existing works on this topic do not take advantage of all the available contextual match data and dismiss potentially valuable information. To address this problem we develop TTIR, a contextual recommender model derived from the Transformer neural architecture that suggests a set of items to every team member, based on the contexts of teams and roles that describe the match. TTIR outperforms several approaches and provides interpretable recommendations through visualization of attention weights. Our evaluation indicates that both the Transformer architecture and the contextual information are essential to get the best results for this item recommendation task. Furthermore, a preliminary user survey indicates the usefulness of attention weights for explaining recommendations as well as ideas for future work.

Is “Good Enough” OK? Undergraduate Search Behavior in Google and in a Library Database

Based on our experience as reference librarians and a review of the literature, it is clear that students are choosing to use Google over library databases when beginning their search for information. Reasons such as ease of access and navigation, convenience, and the use of natural language without having to apply rules of searching are mentioned by library users. And while the search results may not be the most relevant, they are often “good enough” for the novice searcher. For our study at the University of Kansas Libraries, we observed and compared how undergraduate students searched for information using Google and an academic library database on specific topics. In particular, we were interested in knowing: • which interface was preferred by students (Google or licensed database; basic or advanced)? • were the students satisfied with the results of their searches? • which features did they use, if any? We identified a small group of undergraduate students and used a pre-observation survey to collect demographics and gauge prior searching experience. The students were asked to search for information on specific topics, using Academic Search Premier (an EBSCO product) and Google. Data were collected through observation, interviews, and use of Morae software installed on the computer. Before they began searching, we encouraged the students to verbalize the steps they were taking throughout their search process. This enabled us to gain additional insights into their techniques or strategies. After the searches were completed, a post-observation “de-briefing” session was conducted with the students to allow us to gather additional comments or questions about their experiences or preferences. Observations from the survey will be shared with reference and instruction staff to provide a better understanding of undergraduate search behavior and possibly to modify pre-conceived notions of how students search. The survey can provide a basis for discussions on meeting expectations of information seekers who have grown up with the Internet and how to do a better job in marketing the library’s licensed resources to undergraduate students. Database vendors could be encouraged to develop interfaces that are more familiar and user friendly or Google-like in its searching mechanisms.Brick and Click Library Symposium 200

Genome-wide association analysis identifies six new loci associated with forced vital capacity

Forced vital capacity (FVC), a spirometric measure of pulmonary function, reflects lung volume and is used to diagnose and monitor lung diseases. We performed genome-wide association study meta-analysis of FVC in 52,253 individuals from 26 studies and followed up the top associations in 32,917 additional individuals of European ancestry. We found six new regions associated at genome-wide significance (P < 5 × 10−8) with FVC in or near EFEMP1, BMP6, MIR129-2–HSD17B12, PRDM11, WWOX and KCNJ2. Two loci previously associated with spirometric measures (GSTCD and PTCH1) were related to FVC. Newly implicated regions were followed up in samples from African-American, Korean, Chinese and Hispanic individuals. We detected transcripts for all six newly implicated genes in human lung tissue. The new loci may inform mechanisms involved in lung development and the pathogenesis of restrictive lung disease

The impact of the metabotropic glutamate receptor and other gene family interaction networks on autism.

International audienceAlthough multiple reports show that defective genetic networks underlie the aetiology of autism, few have translated into pharmacotherapeutic opportunities. Since drugs compete with endogenous small molecules for protein binding, many successful drugs target large gene families with multiple drug binding sites. Here we search for defective gene family interaction networks (GFINs) in 6,742 patients with the ASDs relative to 12,544 neurologically normal controls, to find potentially druggable genetic targets. We find significant enrichment of structural defects (P≤2.40E-09, 1.8-fold enrichment) in the metabotropic glutamate receptor (GRM) GFIN, previously observed to impact attention deficit hyperactivity disorder (ADHD) and schizophrenia. Also, the MXD-MYC-MAX network of genes, previously implicated in cancer, is significantly enriched (P≤3.83E-23, 2.5-fold enrichment), as is the calmodulin 1 (CALM1) gene interaction network (P≤4.16E-04, 14.4-fold enrichment), which regulates voltage-independent calcium-activated action potentials at the neuronal synapse. We find that multiple defective gene family interactions underlie autism, presenting new translational opportunities to explore for therapeutic interventions

Woman-Centered Design through Humanity, Activism, and Inclusion

Women account for over half of the global population, however, continue to be subject to systematic and systemic disadvantage, particularly in terms of access to health and education. At every intersection, where systemic inequality accounts for greater loss of life or limitations on full and healthy living, women are more greatly impacted by those inequalities. The design of technologies is no different, the very definition of technology is historically cast in terms of male activities, and advancements in the field are critical to improve women's quality of life. This article views HCI, a relatively new field, as well positioned to act critically in the ways that technology serve, refigure, and redefine women's bodies. Indeed, the female body remains a contested topic, a restriction to the development of women's health. On one hand, the field of women's health has attended to the medicalization of the body and therefore is to be understood through medical language and knowledge. On the other hand, the framing of issues associated with women's health and people's experiences of and within such system(s) remain problematic for many. This is visible today in, e.g., socio-cultural practices in disparate geographies or medical devices within a clinic or the home. Moreover, the biological body is part of a great unmentionable, i.e., the perils of essentialism. We contend that it is necessary, pragmatically and ethically, for HCI to turn its attention toward a woman-centered design approach. While previous research has argued for the dangers of gender-demarcated design work, we advance that designing for and with women should not be regarded as ghettoizing, but instead as critical to improving women's experiences in bodily transactions, choices, rights, and access to and in health and care. In this article, we consider how and why designing with and for woman matters. We use our design-led research as a way to speak to and illustrate alternatives to designing for and with women within HCI.QC 20200930</p

Tolerance, adherence, and acceptability of a ketogenic 2.5:1 ratio, nutritionally complete, medium chain triglyceride-containing liquid feed in children and adults with drug-resistant epilepsy following a ketogenic diet

Objective: To investigate incorporating a ready-to-use 2.5:1 ratio liquid feed into a ketogenic diet (KD) in children and adults with drug-resistant epilepsy. Methods: Following a three-day baseline, patients (n = 19; age: 19 years [SD 13], range: 8–46 years) followed a KD for 28 days (control period), then incorporated ≥200 mL/day of a ready-to-use liquid feed, made with a ratio of 2.5 g of fat to 1 g of protein plus carbohydrate and including medium chain triglycerides ([MCTs]; 25.6% of total fat/100 mL) for 28 days as part of their KD (intervention period). Outcome measures (control vs intervention period) included gastrointestinal (GI) tolerance, adherence to KD and intervention feed, dietary intake, blood ß-hydroxybutyrate (BHB) concentration, seizure outcomes, health-related quality of life (HRQoL), acceptability and safety. Results: Compared to the control period, during the intervention period, the percentage of patients reporting no GI symptoms increased (+5% [SD 5], p = 0.02); adherence to the KD prescription was similar (p = 0.92) but higher in patients (n = 5) with poor adherence (&lt;50%) to KD during the control period (+33% [SD 26], p = 0.049); total MCT intake increased (+12.1 g/day [SD 14.0], p = 0.002), driven by increases in octanoic (C8; +8.3 g/day [SD 6.4], p &lt; 0.001) and decanoic acid (C10; +5.4 g/day [SD 5.4], p &lt; 0.001); KD ratio decreased (p = 0.047), driven by a nonsignificant increase in protein intake (+11 g/day [SD 44], p = 0.29); seizure outcomes were similar (p ≥ 0.63) but improved in patients (n = 6) with the worst seizure outcomes during the control period (p = 0.04); and HRQoL outcomes were similar. The intervention feed was well adhered to (96% [SD 8]) and accepted (≥88% of patients confirmed). Significance: These findings provide an evidence-base to support the effective management of children and adults with drug-resistant epilepsy following a KD with the use of a ready-to-use, nutritionally complete, 2.5:1 ratio feed including MCTs. Plain language summary: This study examined the use of a ready-to-use, nutritionally complete, 2.5:1 ratio (2.5 g of fat to 1 g of protein plus carbohydrate) liquid feed, including medium chain triglycerides (MCTs), into a ketogenic diet (KD) in children and adults with drug-resistant epilepsy. The results show that the 2.5:1 ratio feed was well tolerated, adhered to, and accepted in these patients. Increases in MCT intake (particularly C8 and C10) and improvements in seizure outcomes (reduced seizure burden and intensity) and KD adherence also occurred with the 2.5:1 ratio feed in patients with the worst seizures and adherence, respectively.</p

The impact of COVID-19 on the social and cultural integration of international students: a literature review

This systematic literature review summarises the state-of-the-art evidence on the impact of COVID-19 on the integration of international students in their host countries and institutions. Conducted between January and May 2022, it analyses the responses to COVID-19 of the key actors involved in international student mobility: national/regional authorities, higher education institutions, and students. Findings reveal that governmental action and institutional measures were decisive in shaping international students’ integration experiences. Regarding governmental action, criticism of the policies adopted by Australia and the USA in relation to immigration and/or support stand out, in contrast to policies adopted by the Canadian authorities. Higher education institutions played an important role in mitigating the negative effects of COVID-19 on international students’ integration. These targeted different needs– material, well-being, and social– through different types of support: logistical and financial support, psychological support, and the provision of platforms for ongoing social interaction and exchange. Most studies, however, focus on the students themselves, the challenges they faced during the pandemic and their coping strategies. Common to international students’ lived experience was (dis)connectedness, with the following themes emerging as obstacles to their social and cultural integration: distress during lockdown periods, disruption of their social life and support networks, mental health issues, discrimination and racialised prejudice, and language barriers. The review concludes by proposing recommendations and by identifying avenues for future research
