A Review of: Olson, Tod A. “Utility of a Faceted Catalog for Scholarly Research” Library Hi Tech 25.4 (2007): 550-61. Objective – To learn whether a faceted catalogue and word cloud aids in the discovery process. Design – User study. Setting – Large academic research library in the United States. Subjects – Twelve PhD candidates in the humanities, the majority of whom are engaged with researching, proposing, or writing their dissertations. Methods – The library’s entire catalogue of 5.2 million records was loaded into the AquaBrowser OPAC search interface. A pilot study was conducted using three humanities graduate students employed by the library. Following the pilot, the main study was conducted using graduate students in the humanities. Graduate students in the social sciences were desired for the study, but were not able to be contacted due to time constraints. Once selected, the test subjects were asked to use an interface that offered both facets and tag clouds for enhanced search quality. Test subjects were allowed to choose the topic they would like to research; all chose to research their dissertation topic. A moderator and recorder facilitated research conducted with the faceted catalogue. The moderator ensured that students commented on their findings, cleared up any confusion with using the interface, and kept the students on task. Only when students remarked that a new discovery had been made were those discoveries noted. The impact to the discovery process of faceted navigation and AquaBrowser’s word cloud was studied while the impact of relevance ranking was not. Main Results – The article asserts that results from both the pilot and main study were sufficiently similar to justify combining them for the paper, but the advantage that students employed by the library might have over other students is not discussed. Nine of the twelve students used in the study found new results using the faceted catalogue and word cloud. The responses of the user group to the faceted catalogue and word cloud were “overwhelmingly positive” (555). However, since students were allowed to move freely between the word cloud and faceted navigation tool, it is difficult to attribute new discoveries solely to one or the other. However, when a new discovery could be “attributed primarily to one factor or another” (555) it was noted. The faceted navigation tool aided discovery at least four times and the word cloud aided discovery at least six. Conclusion – A faceted catalogue interface with a word cloud feature clearly aids in the discovery process for more advanced researchers—those with specialized subject knowledge, familiarity with their library’s collection, and experience in researching their area. However, facets and word clouds have limitations: records with limited cataloguing have little to offer faceted navigation; catalogue records from diverse providers introduce controlled vocabularies beyond LCSH and MeSH into search returns, resulting in the same word potentially appearing multiple times in the same return albeit with different meanings; the word cloud may contain certain words that researchers feel to be irrelevant. Despite these issues, the use of word clouds and faceted navigation (and relevance ranking) appears to be beneficial to research conducted by experienced subject searchers in the humanities.

Case Based

Argumentation competence is a major skill to be acquired in university education. However, there is a lack of advanced argumentation competence even for graduate students. To foster argumentation competence, typical interventions focus on example-based learning. Another approach is learning from advocatory errors. The combination of both approaches is presenting examples of erroneous arguments. Drawing on the concept of case-based learning, we developed a learning intervention that presents examples of argumentation errors in a story-based designs, i.e., the erroneous examples are embedded in a story featuring the argumentation between two persons in an authentic setting. In this contribution, we report results of two studies. In a pilot study, we compared an experimental condition receiving a story-based learning intervention with a control condition without a learning intervention. W found that learning from advocatory errors in a story-based design indeed fosters students’ argumentation competence. In a main study, we compared two forms of instructional support (elaboration vs. testing prompts) against a control condition without instructional support. There was a significant increase of argumentation competence in both conditions with instructional support but not in the control condition. The results also support the cautious conclusion that elaboration prompts seem to be more effective than testing prompts. Overall, the results from both studies indicate that the story-based design is apt to foster students’ argumentation competence. We also considered the impact of prior argumentation competence and found in both studies that the present level of argumentation competence is factor determining the argumentation competence after learning.

Abstract Objectives AO Spine REsearch objectives and Common Data Elements for Degenerative Cervical Myelopathy [RECODE-DCM] is a multi-stakeholder consensus process aiming to promote research efficiency in DCM. It aims to establish the top 10 research uncertainties, through a James Lind Alliance Priority Setting Partnership [PSP]. Through a consensus process, research questions are generated and ranked. The inclusion of people with cervical myelopathy [PwCM] is central to the process. We hypothesized that presenting PwCM experience through word cloud generation would stimulate other key stakeholders to generate research questions better aligned with PwCM needs. This protocol outlines our plans to evaluate this as a nested methodological study within our PSP. Methods An online poll asked PwCM to submit and vote on words associated with aspects of DCM. After review, a refined word list was re-polled for voting and word submission. Word clouds were generated and an implementation plan for AO Spine RECODE-DCM PSP surveys was subsequently developed. Results Seventy-nine terms were submitted after the first poll. Eighty-seven refined words were then re-polled (which added a further 39 words). Four word clouds were generated under the categories of diagnosis, management, long-term effects, and other. A 1:1 block randomization protocol to assess word cloud impact on the number and relevance of PSP research questions was generated. Conclusions We have shown it is feasible to work with PwCM to generate a tool for the AO Spine RECODE-DCM nested methodological study. Once the survey stage is completed, we will be able to evaluate the impact of the word clouds. Further research will be needed to assess the value of any impact in terms of stimulating a more creative research agenda.

Sustainable development is a global objective that aims to address the societal challenge of climate action, the environment, resource efficiency, and raw materials. In this sense, an important strategy is the promotion of green packaging, that is, the use of sustainable materials and designs for the packaging of goods. In recent years, many research works have been published in the specialised area covering the different perspectives and dimensions of green packaging. However, to our knowledge, no previous investigations have analysed the research activity on green packaging from business and consumer perspectives. The present study intends to fill this gap by analysing all of the publications found in the Scopus database with the help of visual analytic tools, including word clouds and Gephi network visualization software. More specifically, our study analyses the impact of green packaging from business and consumer viewpoints, including some specific issues such as the design and materials used in green packaging, green packaging costs, marketing strategies and corporate social responsibility related to green packaging, and the impact of green packaging in waste management, the circular economy, logistics, and supply chain management. The results obtained reveal the growing interest of scholars and researchers in all of these dimensions, as is made patently clear by the increasing number of journal publications in recent years. The practical implications of this study are significant, given the growing awareness among companies and consumers about the importance of the promotion of sustainable development through green packaging alternatives. More specifically, the results of this research could be very useful for all of those agents who are interested in learning about the main lines of research being developed in the field of green packaging.

College Premium

Despite increases in the college earnings premium to persistently high levels, investment in college education remains low. We can understand this apparent puzzle by considering the risk of attending college and, in particular, the possibility of failing to graduate. Students with a reasonable probability of completing college already enroll, and for those who do not enroll, the low chance of completion blunts the impact of the rising college premium. In the absence of improved college readiness, our quantitative results suggest that continuing long-standing trends in skill-biased technological change can be expected primarily to increase earnings inequality rather than college attainment.

Insight Into

Corporations have embraced the idea of corporate environmental, social, and governance (ESG) under the general framework of sustainability. Studies have measured and analyzed the impact of internal sustainability efforts on the performance of individual companies, policies, and projects. This exploratory study attempts to extract useful insight from shareholder sustainability resolutions using machine learning-based text analytics. Prior research has studied corporate sustainability disclosures from public reports. By studying shareholder resolutions, we gain insight into the shareholders’ perspectives and objectives. The primary source for this study is the Ceres sustainability shareholder resolution database, with 1737 records spanning 2009–2019. The study utilizes a combination of text analytic approaches (i.e., word cloud, co-occurrence, row-similarities, clustering, classification, etc.) to extract insights. These are novel methods of transforming textual data into useful knowledge about corporate sustainability endeavors. This study demonstrates that stakeholders, such as shareholders, can influence corporate sustainability via resolutions. The incorporation of text analytic techniques offers insight to researchers who study vast collections of unstructured bodies of text, improving the understanding of shareholder resolutions and reaching a wider audience.

INTRODUCTION With the development of a new curriculum, workplace based assessments such as procedure-based assessment (PBA) are becoming increasingly common within surgical training. However, there have been concerns about the impact of these assessments on clinical practice. This study assessed the time taken to complete PBA forms to determine whether it is feasible in clinical practice. MATERIALS AND METHODS PBAs for three colorectal procedures (anterior resection, right hemicolectomy and anal fistula) were undertaken by various trainers and trainees. A pilot study was performed to identify potential reasons for incomplete forms and procedural modifications subsequently applied in the main study. Times taken to complete the consenting and operative components of the forms were recorded. RESULTS Incomplete forms in the pilot were mainly attributable to time constraints. In the main study, all assessments were completed within 30 min. Assessment times increased with complexity of the procedure. Median times for completing the consenting and operative components in anterior resection were 13 min (range, 8–15 min) and 15 min (range, 10–18 min), respectively. CONCLUSIONS PBAs are feasible in clinical practice and are valued by trainees as a means of enabling focused feedback and targeted training. Commitment from trainers and trainees will be required but, with adequate planning, the assessment tool is effective with minimal impact on clinical practice.

This study investigates the effect of the organization performance on two psychological biases, mental accounting and aversion to loss, on financial decisions to both investors and managers. To achieve this, two experiments are conducted. The first experiment consists of 40 graduate students as investors, while the second one consists of 40 accountants in a real estate company as managers. The results of the study indicate that the performance of companies impacts both mental accounting and aversion to loss of investors, whereas the performance of companies affects the mental accounting of managers in making their financial decisions but does not affect the aversion to loss.

Word Clouds

Word clouds manifest interactive visuals along with their statistical data. Thus knowledge discovery and aesthetic data visualization interlink to produce interactive word cloud which is an interesting, textual, statistical and visual data. This study aims to generate interactive word cloud—Cirrus—on the basis of statistical data to preview text of the novel for readers. So cirrus tool is selected from Voyant open access tools to produce interactive statistical word cloud. Then the generated word cloud and statistical data are analyzed with mixed method and its analysis draws insight from Rakesh Aggrawal’s Knowledge Discovery Theory which seeks innovative and interesting knowledge patterns. This thematic word cloud verifies already known themes and discovers innovative interesting themes. Current study reveals that all mentioned key themes can be easily extracted from a voluminous novel with the help of Cirrus tool. Key motifs have been presented in the word cloud for the readers. On the other hand, unwritten themes can’t be extracted through machine learning tools, rather it is the task of human cognition. Primarily, this novel based study reveals names of chief characters, for instance “Tommy (496),” “Ruth (455)” and “I (Kathy) (355).” Furthermore, motifs of nostalgic memories with word “remember (143),” “thought (126)” about “Hailsham (203),” “carer (74),” “sex (80),” sex “lectures (8)” have been discovered as a preview. Previewing technique prepares reader’s mind and gives an epigrammatic digital view of the text. The visual themes as knowledgeable word cloud leave an indelible mark on the slate of memory.

Evidence of adaptive immune responses in the prevention of cancer has been accumulating for decades. Spontaneous T-cell responses occur in multiple indications, bringing the study of de novo expressed cancer antigens to the fore and highlighting their potential as targets for cancer immunotherapy. Circumventing the immune-suppressive mechanisms that maintain tumor tolerance and driving an antitumor cytotoxic T-cell response in cancer patients may eradicate the tumor or block disease progression. Multiple strategies are being pursued to harness the cytotoxic potential of T cells clinically. Highly promising results are now emerging. The focus of this review is the target discovery process for cancer immune therapeutics based on affinity-matured T-cell receptors (TCRs). Target cancer antigens in the context of adoptive cell transfer technologies and soluble biologic agents are discussed. To appreciate the impact of TCR-based technology and understand the TCR discovery process, it is necessary to understand key differences between TCR-based therapy and other immunotherapy approaches. The review first summarizes key advances in the cancer immunotherapy field and then discusses the opportunities that TCR technology provides. The nature and breadth of molecular targets that are tractable to this approach are discussed, together with the challenges associated with finding them.
