Crafting Open Research Advocacy Messages Using Diffusion of Innovation Theory
Authors: Skelly Lara , Rusu Cristina
Published: June 2023

Drawing parallels between the Open Research (OR) movement and traditional for-profit business strategies provides useful insight to those who are championing OR practices. Adopters of OR practices are akin to a customer base, and the common focus is to expand.
Roger’s Diffusion of Innovation curve provides a market segmentation according to the number of consumers/adopters. Rogers provides descriptors of these ideal types (2003, 282-285). Cross-tabulating the ideal types with the initial constructs in the Unified Theory of Acceptance and Use of Technology (Venkatesh, et al. 2023), provides inspiration to craft targeted messages for different types of adopters, which will hopefully lead to behavioural intention and ultimately undertaking an OR practice. These initial constructs are performance expectancy (what kind of expectation the adopter will have of the practice), effort expectancy (how much effort the adopter is willing to put into making a new practice work for them) and social influence (how they are likely to be influenced by others).
Teaching the Best Research Data Management Practices to PhD Students
Authors: Kapoor Ishwar
Published: June 2023

Good Research Data Management (RDM) practices make it easier for researchers to conduct their research and ensure their data is preserved and stored securely for the long-term. Archiving is one of the last stages of Research Data Lifecycle and deals with depositing and preserving datasets at the end of a project in a suitable storage location (repositories, local server, or hard drive).
Students may not find data management topic as interesting as their core course topics. This can result in lack of students’ knowledge of the importance and benefits of good data management practices for their studies. At Warwick, I design and deliver Research Data Management & Planning (RDM&P) case study sessions to PhD students. Students learn different elements of RDM and importance of RDM for long-term preservation. Students work in groups to develop and present Data Management Plan (DMP) and put RDM&P learning into practice.
In this presentation, I briefly introduce the above case study, feedbacks received from students across different disciplines and further steps.
Open Science Hardware for Realising Globally Equitable Knowledge Production
Authors: Hsing Pen-Yuan , Johns Brianna
Published: June 2023

Physical hardware underpins research in many disciplines. From computing devices, scientific instrumentation, and biological reagents, to remote sensing satellites, researchers rely on hardware to explore and understand the world. However, research equipment is typically based on closed source (i.e. proprietary) hardware, whose designs are legally restricted, preventing others from studying, building, or modifying them. These restrictions cause several problems such as: lack of reproducibility; duplication of effort; forced obsolescence; and higher costs.

Crucially, the inefficiencies of closed source hardware reinforce global inequities. This is because the design and manufacturing of research equipment is often monopolised by producers in the Global North. Restricted access to hardware designs mean that only authorised dealers and technicians are allowed to sell or maintain equipment. These services are often unavailable to, or prohibitively expensive for, researchers belonging to historically marginalised communities outside of the Global North.

Building on the success of open source software, open source hardware is defined as any physical artefact whose “design is made publicly available with explicit, legally binding freedoms for anyone to study, modify, distribute, make, and sell the design or hardware based on that design”. Open science hardware is an emerging field of practice which studies and applies the principles of open source hardware to research contexts. In 2021, it was formally recognised as a key component in the UNESCO Recommendation on Open Science. Open science hardware provides many benefits compared to its proprietary counterparts. This can include cost savings of up to 87% (Pearce, 2020) and proportional to how often it is replicated; quicker iteration of designs; and adaptation to local needs in underserved communities.

Since the 2010s, open science hardware has been developed and used in diverse domains from environmental monitoring, and lab automation, to microscopy. In addition to academics, open science hardware is commonly built by citizen science communities and adapted for different purposes. Other practitioners of open science hardware include educators, social innovators, or artists.

In this talk, we provide an overview of open science hardware and the problems it solves. We also provide successful examples of open science hardware projects that serve to not only do good science, but also address global inequities. The talk also presents the Gathering for Open Science Hardware, an international network working towards the adoption of open source hardware across research lifecycle.
How Data Papers Present a Unique Contribution To Open Research In The Humanities And Social Sciences
Authors: Wigdorowitz Mandy , McGillivray Barbara , Ribary Marton
Published: June 2023

The open research movement and initiatives like the FAIR principles have been critical in establishing the importance of data in research, particularly within the sciences. Alongside the sciences, attention to openly available data in Humanities and Social Sciences (HSS) research has gradually grown. This growth is largely attributed to the increased availability of digital collections, the development of new data-intensive methods, an increasingly solid infrastructure, increased pressure from funders, the requirement of data management plans for preservation purposes, and the involvement of research libraries in data curation. In this context, attention to how data is produced, how it is openly and transparently shared, and how it can be reused has generated great interest, accompanied by an inevitable need for reputable data sharing outlets. One such outlet is the data paper – a peer-reviewed publication that focuses on describing a curated dataset. Data papers can be shared in traditional research journals as one subtype of article publication, or, more recently, in data journals which are dedicated to the publication of data papers. This presentation focuses on the work done by the open access Journal of Open Humanities (JOHD) in promoting the practice of publishing data papers with their accompanying open access datasets. JOHD was established with Ubiquity Press in 2015 to promote awareness, use, and reuse of humanities data. JOHD data papers promote the comprehensive description of how a dataset was assembled, where it may be accessed, and any crucial context including the research questions that framed the data gathering, including limitations to the original methods or scope of sources included. JOHD data papers suggest potential future reuses of data, which recent analytics seem to suggest has helped increase the visibility of datasets, and therefore their research impact (Marongiu et al., forthcoming; McGillivray et al., 2022). In addition, an overview of the three key elements (the “golden triangle”) that assess the impact of open research efforts as represented by different research outputs (datasets, data papers and research papers) will be presented, along with proposed initiatives for linking these. In doing so, we aim to (a) find a programmatic way to identify these links by extracting information from available metadata of datasets and verifying their accuracy, and (b) create a “ground truth” in a manual and/or machine-assisted way which would enable the training of more sophisticated NLP-based methods as a next step. We hope to illustrate the importance of including data papers into the research conversation given that they present a unique contribution to addressing global challenges within the open research arena.

Authors: Ricardo Jiménez Luly Stephanie , Romero Osorio Fray Ramiro , Navarro Flórez Pedro Juan , Puentes Lozano Hernando
Published: June 2023

Al hablar de calidad se debe tener claro que es algo subjetivo, por lo que se puede definir como el cumplimiento de requisitos del cliente. Existen sectores, como el de restaurantes, en donde se debe combinar la prestación del servicio y el producto entregado para medir la calidad. Esta investigación tiene como objetivo evaluar las condiciones de la prestación del servicio al cliente usando el modelo cuantitativo Dineserv y el efecto que esta tiene en la rentabilidad de los restaurantes de la zona norte de Montería. La herramienta Dineserv utiliza 29 preguntas que permiten conocer el grado de satisfacción con respecto al servicio prestado y el producto entregado, e identificar las no conformidades que tienen los clientes en los restaurantes. El análisis estadístico se hizo mediante un análisis factorial, el cálculo de estadísticos como la desviación estándar, y la media. Finalmente, se conoció el grado de calidad que tiene el servicio ofrecido a los comensales de restaurantes en la ciudad de Montería y la relación con la rentabilidad de los establecimientos.

Published: June 2023

Abstract: Extractive text summarization is the process of identifying the most important information from a large text and presenting it in a condensed form. One popular approach to this problem is the use of centroid-based clustering algorithms, which group together similar sentences based on their content and then select representative sentences from each cluster to form a summary. In this research, we present a centroid-based clustering algorithm for email summarization that combines the use of word embeddings with a clustering algorithm. We compare our algorithm to existing summarization techniques. Our results show that our approach stands close to existing methods in terms of summary quality, while also being computationally efficient. Overall, our work demonstrates the potential of centroid-based clustering algorithms for extractive text summarization and suggests avenues for further research in this area.

Abstract: In the vast world of cinema, numerous critically acclaimed movies often go unnoticed, despite their significant artistic and cultural value. Recognizing this disparity, our research endeavors to bridge the gap by developing a comprehensive movie recommendation system that highlights these "Out of the box" films. In the initial phase, we meticulously collected a bespoke dataset by scraping data from IMDb, encompassing a wide range of movies from various genres and regions. In the subsequent phase, we constructed an advanced algorithm utilizing content-based filtering techniques. This algorithm analyzes both user behavior and movie features to provide personalized recommendations that align with users' unique preferences. By embracing this approach, our research aims to enhance the discoverability and appreciation of lesser-known yet meaningful movies, empowering users to explore a diverse array of cinematic experiences.

Ketika Rasulullah SAW. membangun masjid, baik untuk yang pertama di Quba' maupun di Madinah, tidak hanya dimaksudkan untuk sarana beribadah kepada Allah SWT semata. Lebih dari itu masjid juga digunakan sebagai sarana mencerdaskan umat, sebagai sarana berkomunikasi antara umat dan sekaligus sebagai pusat kegiatan umat secara positif dan produktif. Kondisi ini kemudian juga dilestarikan oleh para penggantinya (khulafa' al-Rasyidun). Namun seiring dengan berlalunya zaman, masjid mulai ditinggalkan umatnya, kecuali hanya untuk beribadah semata. Masjid hanya dijadikan tempat untuk melaksanakan shalat, pengajian dan kegiatan-kegiatan keagamaan saja. Dengan itu pengelolaan masjid perlu penanganan khusus. Apalagi kondisi Masjid di Klaten perlu perhatian dalam rencana penguatan dakwah disegala aspekbaik pemberdayaan umat dan ekonomi.

Differentiation model learning is an effort to facilitate students' diverse or different backgrounds so that students are able to maximize their abilities. This study aims to improve students' mathematical reasoning using the google site-assisted differentiation learning model. Mathematical reasoning is one that is important for students to master, especially class X. The method in this study was quasi-experimental, with 68 students were participated in this research from SMA PGRI 31 and SMAN 1 Pangalengan. The instruments in this study were 5 questions describing mathematical reasoning. Data were analyzed using SPSS 23 to compare between conventional learning and learning using the google site-assisted differentiation model. The results show that students who have the differentiation model were better than those using conventional learning. This shows that the class using the differentiation learning model has an advantage in reasoning ability. This is because children learn according to their respective abilities because in the differentiation of the teaching provided it is adjusted to the initial ability there is yes ng children need a lot of guidance or Scaffolding, there is a little, there is no guidance so that they are able to maximize the mathematical reasoning that children have. From the results of the study it can be concluded that there is a significant difference between learning using the Google site-assisted differentiation model and conventional learning.

Purpose: The incidence of glufosinate poisoning is gradually increasing, and it can be fatal if severe poisoning occurs. However, factors useful for predicting the post-discharge neurological prognosis of patients who have ingested glufosinate have yet to be identified. Our objective was to evaluate the utility of the acute physiology and chronic health evaluation (APACHE) II score measured in the emergency department for predicting the neurological prognosis. Methods: From April 2012 to August 2014, we conducted a retrospective study of patients who had ingested glufosinate. The outcome of the patients at discharge was defined by the Cerebral Performance Category Score (CPC). The patients were divided into a good prognosis group (CPC 1, 2) and a poor prognosis group (CPC 3, 4, 5), after which the APACHE II scores were compared. The Hosmer-Lemeshow test and the area under the receiver operating characteristic (ROC) curve from patients determined calibration and discrimination. Results: A total of 76 patients were enrolled (good prognosis group: 67 vs poor prognosis group: 9). The cut-off value for the APACHE II score was 12 and the area under the curve value was 0.891. The Hosmer and Lemeshow C statistic x2 was 7.414 (p=0.387), indicating good calibration for APACHE II. Conclusion: The APACHE II score is useful at predicting the neurological prognosis of patients who have ingested glufosinate.
