Representation in the UK MS Register: A Comparison of Nationwide Ethnicity and Register Data
Authors: Middleton Rod , Craig Elaine
Published: September 2024

BackgroundThe United Kingdom MS Register (UKMSR) collects longitudinal data on people with Multiple Sclerosis (pwMS) from clinical sources and as Patient Reported Outcomes (PROs) via a web portal. People from non-white ethnicities are often poorly represented in research and clinical trials; the UKMSR aims to be representative of people with MS (pwMS) across the UK.
AimTo compare ethnic representation in the UKMSR to data from the Office for National Statistics (ONS).
MethodEthnicity data was taken from the UKMSR as a ‘snapshot’ in 2024. Comparative data from ONS in England and Wales was gathered. Due to low numbers in the UKMSR of some ethnicities and areas, participants were grouped into ‘White’ and ‘All Other Ethnicities’. Using Chi-Sq tests, we compared ethnicities across ten regions of ONS 2021 Census data.
ResultsTen regions were compared (nine in England, Wales as one). Analysis of both web-reported (n = 18648) and clinical (n = 5456) ethnicity found UKMSR diversity to be significantly lower than national statistics (p < .05), with the exception of the clinical Register in Wales (numbers were insufficient to test) and clinical Register in the English West Midlands. The clinical Register was more representative in 7/10 regions than the web Register.
DiscussionThe clinical Register, via NHS hospital sites reaches a more diverse audience than the patient-reported web Register; further work is needed in reaching a broader audience of pwMS, as well as harmonising discrepancies between the clinical and web Register populations.
Balancing Privacy and Precision: Evaluating Meta-Analysis for National Health Data Integration in Canada

Published: September 2024

BackgroundIn Canada, legislative restrictions exist for the disclosure and transfer of patient data across provincial boundaries. Often, meta-analysis techniques are employed to pool province-specific results to enable national results while maintaining compliance with privacy legislation. However, the effectiveness of this technique remains unexamined using electronic data. To evaluate its performance, we compare results obtained through meta-analysis with those from a fully pooled model.
MethodsUsing chronic kidney disease as a case study, this retrospective cohort study simulates the meta-analysis method to evaluate its performance using real data. We analyze data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN), a nationwide database of electronic medical records. We meta-analyze provincial logistic regression models to predict nephropathy over a 5-year period at a national level. Estimates are compared to a fully pooled national model.
ResultsAnalyses are currently ongoing. We expect the meta-analysis technique to produce similar estimates compared to the fully pooled model. However, we expect certain differences as meta-analysis techniques are insensitive to heterogeneity within provinces that impact the precision of estimates. Observed differences will help to inform future work where we will examine a potential new methodology to analyze health information without sharing patient data.
ConclusionsBased on our results, we will reveal strengths and limitations of the meta-analysis technique for interprovincial analyses. Limitations of the meta-analysis technique may underscore the need for further exploration into alternative methodologies that can effectively analyze health information without compromising patient privacy to facilitate better healthcare decision-making and policy development in Canada.

Objective and ApproachPrior research has found that experiences of homelessness are associated with an increased likelihood of child protection involvement, and vice-versa. However, it is not clear how involvement with the child welfare system may impact family housing stability during and after their involvement. The objective of this study was to more deeply understand the housing stability of families involved with child welfare over time.
To examine this issue, we linked administrative data from Minnesota’s Homelessness Management Information System with social services data from the Department of Human Services (e.g., receipt of food support, childcare or housing assistance, child welfare), for families involved with child welfare in Minnesota between 2019 and 2021. 
ResultsApproximately a quarter of child welfare-involved families experienced homelessness during their involvement with the child welfare system. Rates of homelessness were similarly high in the two years prior to and following child welfare involvement. Although a large proportion of families experienced homelessness before and during their child welfare involvement, we saw no increase in the proportion of families receiving housing support after their involvement in the system. 
Conclusions and ImplicationsOur findings indicate that involvement with the child welfare system and the resources provided through this involvement do not have a significant impact on family’s experiences of homelessness. This suggests the need for closer collaboration between the child welfare system and housing services to identify more effective solutions for housing instability among families within the child welfare system.

Authors: Sandhu Namneet , Whittle Sarah , Varela Lucia Otero , Eastwood Cathy A , Southern Danielle A , Quan Hude
Published: September 2024

IntroductionGlobally, differences in coding practices and guidelines lead to variations in hospital-administrative data. Studies on patient safety found that better hospital-data quality is associated with higher rates of patient safety events. This study outlines our process of creating a standardized tool for countries to assess their hospital-administrative data quality.
ApproachWe developed 24 indicators across five different dimensions through a Delphi-consensus method. To test applicability of these indicators, we approached representatives from 50 countries with an online survey comprised of qualitative and quantitative questions. Characteristics of each country and indicator scores were noted. A data quality overall score, out of 20, was calculated for each country based on survey responses. The score was classified into 3 data quality categories: high (≥18), moderate (13-17.9), and low (<13).  
ResultsOf the 50 countries invited, 17 responded. Surveys from two countries were excluded due to insufficient data. Country responses (n=15) were evaluated and scored by dimension. The data quality indicators showed positive face validity and were applicable for most countries providing comparative information for development of the tool with good discrimination. Canada, USA, New Zealand, UK, and Spain were among the countries with an overall high data quality score (≥18). Most countries scored high in 3 out of 5 dimensions of data quality. A few countries scored 0 out of 4 in ‘Relevance’ and ‘Timeliness’ dimensions resulting in a lower overall score. 
ConclusionWe propose our developed tool be used for comparing hospital-administrative data quality for applying the same standard across countries.
The Fundamental Role of Linkage Uncertainty in Epidemiological Analysis of Big Data
Authors: Bor Jacob , Lauren Evelyn
Published: September 2024

BackgroundEpidemiologists increasingly work with linked “big data”. Uncertainty in record linkage may lead to biased inferences but is often overlooked. We evaluate the impact of linkage uncertainty on statistical inference in linked big data.
MethodsWe developed a graphical framework for describing linkage uncertainty when linking multiple representations of the same entity, applied to de-identified data from South Africa’s national laboratory database. Through simulation, we systematically introduced linkage errors and measured their impact on overall accuracy (sensitivity, positive predictive value (PPV)). We evaluate how linkage errors affect bias and variance in point estimates for a hypothetical parameter of interest in clinical epidemiology: 24-month retention in care for HIV patients. We compare the roles of sampling error vs. linkage error as fundamental sources of uncertainty in datasets of varying sizes.
ResultsWe simulated a population of 14,393 HIV patients, with a “true” 24-month retention of 38.7%. There were 338,056 true links. Introducing 4,200 false links reduced PPV by 5%. Removing 21,500 existing links decreased sensitivity by 5%. From 10 simulation runs, a 95% sensitivity led, on average, to a 7.4% overestimate in entries to care and a 2.2% (range: 2.1-2.4%) underestimate in 24-month retention. A 95% PPV resulted, on average, in a 7.5% underestimate in entries to care and a 1.8% (range: 1.5-2.0%) overestimate in 24-month retention.
ConclusionWe observe that in a large sample, linkage uncertainty minimally impacts variance in point estimates but has a potentially large influence on the magnitude and direction, distinguishing it from typical sampling errors.
Platform enabling population-level imaging and data linkage in Scotland

Published: September 2024

Scotland has more than five million people within a single health system, using a single central Picture Archiving and Commication System (PACS) for radiography data. This enabled the project team to build a research resource exceeding a petabyte of imaging from 2010 onwards, with open-source tooling to collate and de-identify images on demand. Image metadata, treatment and diagnostic records can be used to define large  cohorts of patients then make the data available remotely to researchers in a Trusted Research Environment (TRE).
Original identifiable images are stored in one of three isolated zones with controlled data transfer to protect patient privacy and prevent inadvertent disclosure. Linkage to other records is performed in the second zone on de-identified images using encrypted patient identifiers. Automated screening with optical character recognition and natural language processing was implemented to identify and redact personally identifiable information before release to researchers in the third zone.
A recent extension to this system has provided an ongoing feed of routine imaging, which is securely shared with regional counterparts to ensure the minimal possible additional load is placed on clinical PACS resources and avoid duplicate requests.
The project launched in April 2022 and since then a variety of research projects have already used this environment and data representing millions of pounds of funding, some using large cohorts with historical data up to 14 years old, re-assessing historical scans with the benefit of subsequent diagnosis to investigate possible early warning signs of conditions including dementia and pre-cancerous lung nodules.

Published: September 2024

The aim of this study was to evaluate the performance of a computable phenotype for systemic lupus erythematosus (SLE) patients when it is ported from a local data warehouse to the i2b2, OMOP, and PCORnet CDMs.
We adapted the SLE phenotype to the Northwestern Medicine (NM) Enterprise Data Warehouse (EDW) and NU i2b2, OMOP, and PCORnet instances. Each of the phenotype’s 17 components were determined by a rules-based algorithm built on diagnosis, medication, lab, and procedure codes. We assessed the phenotype over 168 clinician-confirmed SLE patients and 100 healthy controls and calculated agreement between the EDW and CDMs for overall SLE classification, individual SLICC criteria membership, and individual code occurrence level aggregates - count, first and last date, lab values using Cohen’s kappa (Cκ) and intraclass correlation coefficients (ICC).
For overall SLE classification, agreement of the OMOP and PCORnet datamarts with the EDW was high (Cκ 0.928, 0.802, respectively) while that of i2b2 was low (Cκ 0.328). For the panel of SLICC criteria, OMOP had high agreement for 14/17 SLICC criteria (Cκ 0.792-1.000). PCORnet had high agreement for 13/17 criteria (Cκ 0.708-1.000). i2b2 had high agreement for 10/17 criteria (Cκ 0.813-1.000) with the exception of lab-based criteria.
While agreement between the EDW and CDMs at the level of individual codes was relatively poor, agreement at the levels of overall SLE classification and individual SLICC criteria were reasonably high for OMOP and PCORnet, suggesting that inconsistencies at a micro, code level become less apparent at the macro, phenotype level.

Sharia Hotel Management Policy: An Analysis of Islamic Attribute of Destination Theory in Indonesia and Malaysia
Authors: Qolbi Fikri 'Ainul , Alam Faizan
Published: September 2024

Islamic Destination Attributes play an essential role in influencing Muslim travelers' interests. This study analyses IAD by comparing Indonesia and Malaysia's current Islamic hotel policies. It was found that there are four dimensions of IAD, namely Worship Facilities, Islamic Facilities, General Islamic Facilities, and Halal Food, which are in accordance with Fatwa Number 108/DSN-MUI/X/2016 fifth article and MS 2610 2015 fourth and fifth articles. IAD is essential for Muslim hotel customer satisfaction. Both policies have fulfilled these four criteria. This study can contribute to academics and researchers in developing a more profound IAD theory. Although limited to the Islamic hotel sector, IAD studies can develop in other sectors with the same policy, such as travel agencies or tour guides.

Published: September 2024

Micro, Small, and Medium-Sized Enterprises (MSMEs) play a significant role in Banjarmasin City's local economic development. Along with this growth, halal products have great potential to gain the support of consumers whose awareness of halal products is increasing. Halal factors are becoming increasingly important to consumers when making routine product purchases. This study examines how the motivation,religiosity, halal literacy, and halal awareness of MSME (Micro, Small, and Medium Enterprises) actors affect their desire to get halal certification in Banjarmasin City. This study is conducted using field research using a quantitative descriptive technique. Purposive sampling, a non-probability sampling technique, selects samples based on the requirement to meet specific objectives, such as identifying MSMEs in Banjarmasin for a minimum of one year. A questionnaire is used for data collection, and the sample size is 96. Using SPSS 25.0 for Windows applications,the following data analysis procedures were employed: hypothesis testing, data validity analysis, and descriptive data analysis. The findings indicate that MSMEs' interest in Halal Certification in Banjarmasin City is significantly influenced, at least in part, by the factors of Halal Literacy, Halal Awareness, Motivation, and Religiosity. The factors significantly impacting MSMEs' interest in halal certification in Banjarmasin City simultaneously include motivation,religiosity, halal literacy, and halal awareness.
Textual Cohesion and Coherence in Translation of Historical Text: An E-C Translation Case Study of The Revolution of 1848 (Excerpts)
Authors: Sun Youya , Hua Jing
Published: September 2024

Focusing on the differences between English and Chinese cohesive and coherent means, this paper studies the E-C translation strategies for transferring coherence in the Chinese version of the selected chapters of the historical book The Revolution of 1848. With Wang Dongfeng’s four types of coherence and Halliday and Hasan’s theory of text cohesion as a theoretical framework, some typical translation cases from the excerpts are analyzed. It is found that the major differences in grammatical cohesion between English and Chinese make it necessary to use different translation methods to achieve grammatical coherence. Secondly, for some means of reiteration, their semantic coherence should be reproduced in the target text; the translation strategies of complicated co-occurrence relations need to be adopted based on the specific context. Thirdly, in addition to the fidelity rule, the word selection should align with different stylistic features on the translation of various writing types, forming stylistic coherence. Fourthly, the cultural information hidden in the source text (by default) could be restored with annotations added to produce pragmatic coherence concerning the preciseness of historical books and cultural differences between East and West.

Published: September 2024

Introduction

Social prescribing (SP) is a holistic and collaborative approach to help individuals access community-based supports and services for their nonmedical social needs. The aim of this study was to assess the needs and priorities of Canadian older adults (aged 55 years and older), with a focus on optimizing SP programs for those who are systemically disadvantaged and socially marginalized.

Methods

Semistructured focus groups (N = 10 groups, 43 participants) were conducted online via Zoom with participants from across Canada. Data transcription and thematic analysis were completed in NVivo. Analyses were informed by self-determination theory.

Results

Our results suggest that older adults desire SP programs that respect their ability to maintain their autonomy and independence, aid and facilitate the development of connectedness and belonging, are built on a foundation of trust and relationship-building in interactions with providers and link workers, and prioritize the person and thus personalize SP to the unique needs of each individual.

Conclusion

SP programs should be informed by the values of older adults. As work is currently underway to formalize and scale SP in Canada, personalizing these programs to the unique circumstances, needs and priorities of participants should be a top priority.

Investigation on Tensile Properties of Polylactide-Nanoclay (PLA/ MMT) Surface Modification Nanocomposites
Authors:   School of Engineering, University of Wollongong, MALAYSIA, Rajendran Royan Nishata Royan
Published: September 2024

Polylactic acid (PLA) has gained significant attention as an environmentally friendly biopolymer, but its limited mechanical properties have hindered broader applications. Nanoparticles such as montmorillonite (MMT) offer a promising approach to address this limitation. The intercalation of MMT with polymer chains can significantly impact the mechanical properties of the nanocomposites. Hence, this paper investigated the effect of surface-modified montmorillonite (MMT) nanoparticles on the mechanical properties of polylactic acid (PLA) nanocomposites. The acetylation process of MMT was carried out followed by neutralisation process with NaOH. PLA granules and acetylated-modified MMT were mixed, crushed into granular form, and moulded. The effect of varying concentrations of modified MMTs on the tensile strength, elongation at break, and maximum force of PLA/MMT nanocomposites was evaluated using the ASTM D638 standard. FTIR results showed shifts in peak intensities in regions 2750 cm-1- 2810 cm-1 led to changes in the aliphatic and aromatic regions, which confirmed the presence of acetylation. Controlled surface modification improved interfacial interactions and load distribution, enhancing overall mechanical performance. The incorporation of surface-modified MMT in PLA/MMT nanocomposite increased the maximum force, Young's modulus, elongation at breaks and tensile strength. PLA/1wt% MMT and the PLA/7wt% MMT compositions exhibited good mechanical properties. However, the PLA/5 wt% MMT blendis deemed more suitable for food applications, such as disposable cups, plates, and cutleries, due to its lower elongation point. In conclusion, the hydrophilic properties of MMT and the hydrophobic properties of PLA are compatible due to the synergistic effects during surface modification which enhance the overall performance of the nanocomposites.
Forced Response of a High-Static-Low-Dynamic (HSLD) Stiffness Isolator with Active Stiffness Control
Authors:   Faculty of Electrical Engineering & Technology, Universiti Malaysia Perlis (UniMAP), Pauh Putra Campus, 02600 Arau, Perlis, MALAYSIA, Ab Rahim Muhajir
Published: September 2024

The High-Static-Low-Dynamic (HSLD) stiffness vibration isolators have been exploited in many engineering applications due to its capability in having a wider isolation bandwidth, while maintaining the high static load capacities. However, it will lead to a large payload oscillation at the static equilibrium position, if the source of vibration is an oscillating force originating within the payload. In this case, the considerably large resultant motion of the payload will change the system nonlinearity. An active stiffness control for reducing the displacement amplitude of the payload oscillation subjected to a harmonic force excitation is proposed in this paper. The dynamic model of an actively stiffened HSLD stiffness isolator is introduced, and the approximate analytical expression for forced response is obtained using the Harmonic Balance Method (HBM). The obtained forced response curve has demonstrated that the active stiffness control is able to reduce the system’s force response, particularly at low frequencies with an approximation of 50%. The nonlinearity of the system becomes smaller as the active stiffness control is applied.

Authors:   Faculty of Engineering, Universitas Pembangunan Nasional Veteran, Jl. RS. Fatmawati Raya, Pd. Labu, 12450 Jakarta, INDONESIA, * Armansyah
Published: September 2024

This study focused on optimizing the process of CNC machining to enhance productivity and product quality of surface finish Ra via the process parameters of the cutting speed (vc), feed rate (vf), and cutting depth (doc). Experimentation was performed on workpieces of AA-6061 to investigate the response Ra through variation of the process parameters to analyze their best fit using RSM with 23 full factorial designs L-8 of DOE. The analysis of variance (ANOVA) was then used to find the major contributors among them that were responsible for the Ra. Based on the result, better Ra was obtained at 0.103 μm using the best fit of vf (150 mm/min), vc (220 m/min), and doc (0.1 mm). ANOVA shows vf contributed better Ra followed by vc and doc respectively. In addition, the level of Ra’s was analyzed through contour plots represented by different colours. It continued to analyze the effect of the process parameters via the main effects plot, Pareto chart, and the contour plot in the predictive desirability model, which indicated that the plots and chart confirmed the vf had more influence compared to others. The studyconfirmed that the low-level parameters provided better Ra to be used for polishing.
A Deep Recurrent Neural Network for Predicting Subject-specific Facial Soft Tissue Interaction
Authors:   Institute of Engineering and Technology, Thu Dau Mot University, Binh Duong, VIETNAM, Nguyen Ho-Quang
Published: September 2024

Predicting biological soft tissue interaction is of great interest for developing computer-aided decision systems. This study aims to develop and evaluate a novel deep-learning approach based on the recurrent neural network for predicting facial soft tissue impact with a rubber ball. A computational workflow was established including a subject-specific finite element model of the facial soft tissue under interaction with the rubber ball. A series of simulations under different ball velocities was performed to build the learning database. We implemented a long-short-term memory (LSTM) model and then evaluated its performance using root mean square error (RMSE) and regression coefficient metrics. The obtained results showed a RMSE of 3.13 mm and a Pearson correlation coefficient of 0.98 for soft tissue displacement prediction. A RMSE of 0.001 MPa and a Pearson correlation coefficient of 0.94 was also obtained for soft tissue von Mises stress prediction. The present study showed the robustness and accuracy of the recurrent neural network for predicting complex soft tissue interaction behaviours. Our findings open new avenues for deploying novel deep learning workflow for human-facial softtissue interaction. As perspective, this workflow will be integrated into our interactive facial analysis and rehabilitation system.

Authors:   School of Mechanical Engineering, College of Engineering, Universiti Teknologi MARA, 40450 Shah Alam, Selangor, MALAYSIA, Makhsin Siti Rabizah
Published: September 2024

This work presents a straightforward yet impactful method to enhance optical fibre sensor signals by integrating silver nanostars (AgNS) with graphene oxide (GO-AgNS) as a sensing material. AgNS were synthesized successfully via a one-step chemical reduction method using hydroxylamine as a reducing agent. The concentration of hydroxylamine was varied (7.2, 3.6, 1.8, and 0.9) x 10−4 %v/v to optimize AgNS formation, with the longest spike of the nanostar observed at lower hydroxylamine concentrations, as confirmed by transmission electron microscopy (TEM). UV-visible measurements revealed the highest peak absorption for AgNS synthesized using 0.9 x 10−4 %v/v hydroxylamine, 0.05 M sodium hydroxide, 0.8 mM silver nitrate, and 0.045 M sodium citrate, with an average length of 352.62 ± 59.72 nm measured from TEM images. GO was synthesized via a modified Hummer’s method and mixed with AgNS at varying ratios (1:5, 1:10, 1:15, and 1:20) to form GO-AgNS coatings for the fibre optic probe. The GO-AgNS coating at a ratio of 1:5 exhibited the highest light absorption intensity, enhancing optical signal by 218% compared to GO-coated and 174% compared to AgNS-coated fibre optic sensors. These findings demonstrate that embedding AgNS onto the GO matrix structure as a sensing material significantly improves sensor performance, suggesting promising applications for super-sensitive, cost-effective, and rapid detection in fibre optic-based sensors.

Kacang bambara (Vigna subterranea L.) memiliki potensi dalam mengamankan pasokan pangan dalam menghadapi perubahan iklim karena memiliki manfaat dari aspek kandungan gizi, kesehatan, dan agronominya. Keterbatasan sumberdaya genetik menghambat pengembangan varietas unggul kacang bambara di Indonesia. Pemuliaan mutasi menggunakan kolkisin merupakan salah satu metode untuk meningkatkan keragaman kacang bambara. Penelitian ini bertujuan untuk mengevaluasi keragaman morfologi dan sitologi pada dua generasi kacang bambara yang diinduksi oleh kolkisin pada konsentrasi yang berbeda. Eksperimen dilakukan di dua waktu dan lokasi yang berbeda, yaitu Maret-Juli 2022 di lapangan percobaan Fakultas Pertanian Universitas Brawijaya dan Maret-Juli 2023 di rumah kaca di wilayah Joyo Agung, Lowokwaru, Kota Malang, Jawa Timur. Perlakuan kolkisin dilakukan dengan metode tetes pada pucuk apikal bibit dengan konsentrasi yang berbeda (0, 0,1, 0,2, 0,3, dan 0,4%). Pengamatan karakteristik morfologi dan sitologi dilakukan pada generasi M1 dan M2. Perlakuan kolkisin mempengaruhi perubahan morfologi dan sitologi tanaman kacang bambara pada generasi M1 dan M2. Pada generasi M2, perlakuan kolkisin konsentrasi 0,4% meningkatkan lebar daun sebesar 31%, panjang daun sebesar 32%, waktu berbunga sebesar 28%, lebar biji sebesar 29%, panjang biji sebesar 47%, bobot 100 biji sebesar 3%, lebar stomata sebesar 20%, dan panjang stomata sebesar 25% dibandingkan dengan kontrol. Namun, perlakuan kolkisin menurunkan jumlah daun sebesar 30%, tinggi tanaman sebesar 1%, jumlah biji pertanaman sebesar 58%, bobot biji pertanaman sebesar 56%, dan kerapatan stomata sebesar 15% dibandingkan dengan kontrol. Perlakuan induksi kolkisin menyebabkan peningkatan jumlah kromosom pada generasi M2 sehingga dapat digunakan untuk meningkatkan variasi dan mengatasi keterbatasan sumber daya genetik kacang Bambara.

Authors: Żak Natalia , Adamska Patrycja , Błaszczyk Aleksandra , Jaworska Barbara , Pażyra Aldona , Kusak Natalia , Stanicki Paweł
Published: September 2024

The first clinical case of atypical fibroxanthoma was documented in 1958, and to date, approximately 3,000 patients have been described in the literature with this diagnosis. Furthermore, the recurrence rate or potential for metastasis in atypical fibroxanthoma is estimated to be as low as 2%. It is noteworthy that fibroxanthoma most commonly arises in the head and neck region. Therefore, the clinical case presented here of a patient diagnosed with atypical fibroxanthoma on the left earlobe margin, with suspected disease recurrence after approximately one year, is extremely rare, so we believed it is noticeable to report.

Published: September 2024

The purpose of this study is to provide empirical evidence about the relationship between Organizational Culture and Knowledge Management in public sector organizations in Colombia. This research is based on information obtained from a survey applied to workers in different positions and areas of four organizations in the Colombian government at the departmental level. A survey of 22 items measured Organizational Culture, and 19 items measured Knowledge Management. The results show that the strongest correlation is between a flexible organizational structure and leadership that foments the development of worker capabilities to register and use knowledge. Furthermore, to achieve efficiency the public organizations should foster adaptability to environment, a well-defined management and value-oriented human behavior and overcome barriers such as bureaucracy, inefficient administration, and make adequate knowledge management.
¿Está justificado el antiidentitarismo del marxismo abierto?
Authors: Guíñez Magdalena
Published: September 2024

El artículo explora el antiidentitarismo del marxismo abierto, una corriente contemporánea que propone un sujeto crítico negativo que rechaza las definiciones. Cuestiono si este antiidentitarismo se limita a la abolición de la identidad de clase o si incluye otras identidades ligadas a otras opresiones. Expongo que los teóricos del marxismo abierto tienen una postura insuficiente y ambigua al respecto, que además no es coherente con sus propias pretensiones. Propongo que el antiidentitarismo del marxismo abierto solo es coherente si busca abolir todas las identidades. Esto lo realizo a partir de establecer paralelos con el feminismo y la teoría queer.
¿Nietzsche amigo de Platón? La valentía ante la verdad.
Authors: Galparsoro Ruiz José Ignacio
Published: September 2024

Nietzsche reconoce ser amigo de Platón. Pero esta amistad no impide que le reproche su cobardía por haber emprendido la huida al «mundo verdadero». Platón sitúa así la verdad en un terreno alejado de la vida, favoreciendo el surgimiento de una concepción dogmática. La crítica a esta concepción muestra que Nietzsche es más amigo de la verdad que de Platón. El artículo analiza la concepción nietzscheana de la verdad, caracterizada por su condición interpretativa y perspectivista. Los nuevos amigos de la verdad así considerada serán los filósofos del futuro.

Escuela y transformación social: Otra mirada de la organización educativa
Authors: Rodríguez Díaz Rodiel
Published: September 2024

Dando testimonio del trabajo académico en narrativas biográficas, ejecutado por los autores, el investigador Juan Bautista Martínez Rodríguez, presenta en el prólogo los ejes transversales de la obra: a) la práctica de la investigación narrativa, b) el entramado histórico, epistemológico, reflexivo institucional y el sentido disruptivo, y c) la aspiración de la transformación social en los centros educativos (p.9), en consideración a las organizaciones disruptivas (p.16)
En la antesala de la introducción se describe el origen de la institución, la escuela y su organización en el contexto de la modernidad, situación que logra el molde de sociedad vigente. En consecuencia, la obra toma distancia con “la mirada funcionalista y administrativista” (p.19) que impera en la organización escolar, recalcando en lo emergente e invisibilizado, en aras de cuestionar ¿sobre qué ideas de institución educativa actúa la escuela? (p. 20)
Ahora bien, el libro construido en seis capítulos y un posfacio, expone a profundidad el ADN de la organización escolar, la mirada alterna de la escuela y su transformación social.
“El paraíso perdido en “La Gallina Degollada” y “El Potro salvaje” de Horacio Quiroga”
Authors: Blancas Caballero Adriana Sofía
Published: September 2024

Los relatos “La gallina degollada” y “El potro salvaje”, de Horacio Quiroga, caracterizados por ser lineales, sencillos, y relatados por un narrador extradiegético, logran despertar sensaciones profundas en el lector gracias a la construcción de los personajes y a la descripción. Aunque en una primera lectura no parecen mostrar sino diferencias genéricas y temáticas, presentan un tópico común: el paraíso perdido. En “La gallina degollada”, la pérdida de la felicidad, tan difícilmente adquirida, viene acompañada del horror, mientras que en “El potro salvaje” la pérdida de la juventud, desperdiciada el potro, produce nostalgia. A final de cuentas, la pérdida une estos relatos. En el presente trabajo se explorará el manejo y el sentido de este recurso.
Reconsidering the hierarchic position of the family Dytiscacaridae Hajiqanbar and Lindquist: A proposal for its placement as a separate superfamily within Raphignathina
Authors: Doğan Salih , Koç Kamil , Ueckermann Edward A. , Lindquist Everet E.
Published: September 2024

Mortazavi et al. (2018) described the family Dytiscacaridae Hajiqanbar and Lindquist and placed it in the superfamily Raphignathoidea in the cohort or hyporder Raphignathina. We now consider that this family should be recognised as a separate superfamily within the Raphignathina, based on a detailed comparison with the other superfamilies in this group.
Transpulmonary cardiac output with room temperature saline is accurate and tracks directional changes in anesthetized dogs
Authors: Cannarozzo Cheyenne J. , Araos Joaquin , Martin-Flores Manuel
Published: September 2024

OBJECTIVE

To assess the performance of transpulmonary thermodilution (TPTD) using room-temperature saline (CORT) and waveform-derived continuous CO (CCO) compared with TPTD using iced saline (COICED) as the indicator for measurements of CO in isoflurane-anesthetized dogs.

METHODS

8 Beagles aged 1 to 2 years (7.4 to 11.2 kg) were enrolled in this experimental study from March 21 to 31, 2023. Dogs were anesthetized with 0.01 mg/kg acepromazine, 5 to 6 mg/kg propofol, and isoflurane and were mechanically ventilated. Dogs were instrumented with a central venous catheter and a femoral arterial catheter equipped with a thermistor. The COICED, CORT, and pulse wave-derived CCO values were obtained at baseline, during infusions of phenylephrine and norepinephrine, and during blood withdrawal and replacement. Data were analyzed with a mixed effect model, Bland-Altman plots, and concordance. Percent error was calculated. P < .05 was used for significance.

RESULTS

Data were collected from 8 dogs. Significant effects of time and the interaction of time and method were found. Bland-Altman plots showed negligible bias with limits of agreement between −0.35 and 0.25 L/min for CORT versus COICED and −1.23 and 1.15 L/min for CCO versus COICED. Percent errors were 17.7% and 66.6%, respectively. In the 4-quadrant plots, the concordance rate was 95% and 68% for measurements obtained with CORT and for CCO, respectively.

CONCLUSIONS

Transpulmonary thermodilution using room temperature saline was accurate and able to track changes in CO. Continuous CO had a large percent error and low tracking ability.

CLINICAL RELEVANCE

Transpulmonary thermodilution using room temperature saline is reliable for monitoring CO and obviates the need for iced preparations in clinical scenarios.
The Brain of Pterodactylus
Authors: Edinger Tilly
Published: September 2024

The investigation of the neurocranium of a Pterodactylus elegans and a comparative review of the figures of other Pterodactylus skulls and of the yet undescribed endocranial casts furnish a complete picture of the Pterodactylus brain except the base. The comparisons of the Tithonian Pterodactylus brain with the Cretaceous pterodactyloid and the Liassic and Tithonian rhamphorhynchoid brains show that while the form and position of the nervous centers of the olfactory and optic senses and the position of the cerebellum are avian in everypterosaurian, bird-like form of cerebellum and forebrain are achieved only in the later forms of both suborders.

Experiments on the Upper Stability Limit of Pyrophyllite at 1.8 Kb and 3.9 Kb Water Pressure
Authors: Kerrick Derrill M.
Published: September 2024

The reaction pyrophyllite=andalusite + 3 quartz + water sets a lower limit for the stability of andalusite in quartz-bearing rocks. Tests show complete decomposition of pyrophyllite at 473 degrees + or -7 degrees C and 3.9 kb, 495 degrees + or -7 degrees C at 3.9 to 3.8 kb, and 447 degrees + or -7 degrees C at 1.7 to 1.8 kb. Partial decomposition occurred at 455 degrees + or -7 degrees C at 3.8 to 3.9 kb. Experiments on quartz and andalusite suggest equilibrium at 430 degrees + or -15 degrees C at 3.9 kb, and 410 degrees + or -15 degrees C at 1.8 kb. The present results, considering knowledge of Al 2 SiO 5 polymorphs, allow an appreciable stability field for andalusite and kyanite in quartz-bearing rocks at moderate temperatures, whatever the water pressure.

Authors: Ogrean Claudia , Herciu Mihaela , Tichindelean Mihai
Published: September 2024

The aim of the study is to get a comprehensive understanding of the research landscape at the nexus between business model innovation, sustainability and/or digitalization, in order to determine key research patterns and trends. Accordingly, the following objectives have guided the development of the paper: (a) to examine the dynamics and structure of the research output (articles and citations) on the topic; (b) to explore the network of the most impactful articles; (c) to trace the origins of the research on the topic; (d) to decipher current developments in the research on the topic; and (e) to search for emerging trends in the research on the topic. An advanced search of the SCOPUS database was conducted to identify the relevant literature available; 1195 articles (published between 2014 and 2023) were selected and exported in VOSviewer for bibliometric analysis. The results suggest the emergence of a niche research area in the broad strategic management field, bringing together four related (sub)topics: (1) circular economy and sustainable business models; (2) tools, frameworks and processes for sustainable business model innovation; (3) digitalization and business model transformation; (4) business models for societal and sustainability transitions. For this research area to crystallize, the identified emerging research trends – on digital innovation and technology; strategic management and analytical methods; supply chain and manufacturing; policy, governance and sustainability – need to be further explored, both individually (in search of refinement and clarity) and collectively (in search of consistency and synergy).

A BIBLIOMETRIC ANALYSIS OF STAKEHOLDERS' PERCEPTIONS ON PUBLIC SERVICE QUALITY AND PERFORMANCE. TRENDS, THEMES AND FUTURE DIRECTIONS
Authors: SABIE Oana-Matilda , BUNEA Ovidiu-Iulian , POPESCU Ruxandra-Irina
Published: September 2024

This article undertakes a comprehensive study of worldwide literature gathered from the Web of Science database, using bibliometric analysis. The analysis covers all the years, and most publications are from 1988 to 2024. The primary focus of the inquiry centres on the development of public service concept, public services citizens’ satisfaction, services’ stakeholders, public services’ quality and performance during this period. The assessment of public services quality by citizens has been a prominent subject of scholarly investigation for a considerable period of time. By conducting keyword co-occurrence analysis on pertinent literature, our objective was to uncover dominant themes and track trends over a period of time. Novel insights were obtained by generating density, network, and overlay maps using VOS Viewer software. The keyword co-occurrence analysis performed using VOS Viewer unveiled an intricate and interrelated network of study themes within the literature on stakeholders' perceptions of the quality and performance of public services. The study discovered four main clusters, each reflecting separate yet intersecting research topics. An in-depth analysis of these clusters provides significant insights into the emerging patterns and key areas of interest in this subject. This research provides essential insights for both academic and practical applications in public services, establishing a foundation for future investigations.
