Cooperativas ante la crisis: Estrategias de resiliencia en México frente el COVID 19
Authors: Rivera González Igor Antonio , Rodríguez Reyes Herly Tatiana , Díaz de León Bolaños Denise 
Published: November 2023

La contingencia de COVID 19 ha cambiado drásticamente la economía, las familias, la manera de relacionarse entre personas y en general la sociedad. Las organizaciones, entre estas las de carácter sociales, han tenido que adaptarse a las nuevas maneras de interactuar, para poder sobrevivir, y existen importantes ejemplos de cómo estas organizacionessociales han enfrentado la crisis actual. En este artículo, se busca analizar las estrategias que implementan las cooperativas para asegurar la continuación de sus actividades económicas y sociales frente a la contingencia sanitaria del COVID-19. Para ello, a través del análisis de 5 casos ubicados en la Ciudad de México, se explican las estrategias implementadas por las mismas: adopción de nuevas tecnologías, desarrollo de nuevos conocimientos, redistribución del trabajo, promociones y compras anticipadas y las alianzas con otras cooperativas. Algunos de los hallazgos de esta investigación muestran la relación que existe entre las estrategias implementadas y los principios y valores que caracterizan a estas organizaciones, tales como la solidaridad, ayuda mutua, responsabilidad y la intercooperación. La principal contribución radica en la discusión de cómo las cooperativas son más resilientes ante la crisis, debido a su capacidad de adaptación, más aún aquellas que tienen que ver con la producción y venta de alimentos sanos y agroecológicos, que las organizaciones ubicadas en el giro textil, cultural y de capacitación, a las que les fue más complicado enfrentar esta crisis.
El gasto social y la pobreza multidimensional en Ecuador
Authors: García-Vélez Diego , Núñez-Velázquez José Javier 
Published: November 2023

Uno de los principales instrumentos de política para el combate a la pobreza, principalmente en los países en vías de desarrollo, es el gasto social destinado a servicios como la educación, la salud y el bienestar social. En Ecuador, el monto total destinado a estos tres servicios ha experimentado una tendencia creciente a partir de 2008. En consecuencia, nuestro objetivo es identificar el efecto del gasto social sobre la pobreza multidimensional en Ecuador, para lo cual aplicamos un índice de pobreza multidimensional con base en la teoría de conjuntos difusos, abordándola como un grado de privación en lugar de un atributo de presencia o ausencia, construimos un perfil de pobreza y estimamos un modelo probit multinomial con un pool de datos provinciales para el periodo 2009-2017. Nuestros principales resultados indican que la pobreza se reduce en el periodo de estudio, pero que no todos los grupos poblacionales se han beneficiado en la misma medida, además que el gasto en bienestar social tiene efectos significativos sobre la pobreza multidimensional, pero que el gasto en educación y en salud no son significativos. Esto sugiere que las políticas públicas deben aplicarse en dos vías, una para combatir la pobreza y otra para cerrar las brechas, lo cual conlleva a la ejecución de más y mejor gasto social en los servicios de bienestar social.
Mathematics of Big Data
Authors: Kepner Jeremy , Jananthan Hayden 
Published: November 2023

The first book to present the common mathematical foundations of big data analysis across a range of applications and technologies.
Today, the volume, velocity, and variety of data are increasing rapidly across a range of fields, including Internet search, healthcare, finance, social media, wireless devices, and cybersecurity. Indeed, these data are growing at a rate beyond our capacity to analyze them. The tools—including spreadsheets, databases, matrices, and graphs—developed to address this challenge all reflect the need to store and operate on data as whole sets rather than as individual elements. This book presents the common mathematical foundations of these data sets that apply across many applications and technologies. Associative arrays unify and simplify data, allowing readers to look past the differences among the various tools and leverage their mathematical similarities in order to solve the hardest big data challenges.
The book first introduces the concept of the associative array in practical terms, presents the associative array manipulation system D4M (Dynamic Distributed Dimensional Data Model), and describes the application of associative arrays to graph analysis and machine learning. It provides a mathematically rigorous definition of associative arrays and describes the properties of associative arrays that arise from this definition. Finally, the book shows how concepts of linearity can be extended to encompass associative arrays. Mathematics of Big Data can be used as a textbook or reference by engineers, scientists, mathematicians, computer scientists, and software engineers who analyze big data.
Determinants of using AI-powered discovery services
Authors: Gasparini Andrea Alessandro , Kautonen Heli 
Published: November 2023

In 2023 the scholarly communities are witnessing a spring of Artificial Intelligence (AI) powered tools for scientific work. Scholars are tempted to integrate various time-saving AI applications in their workflow, from data analysis to disseminating research results. Among these novel “research assistants”, several enhanced discovery services apply machine learning to identify the most relevant results for the information seeker and visualize them to the user in innovative ways.
The rapid emergence of these tools has raised concerns about the impact of AI technology on scientific research and led to requirements of transparency, accountability, and explainability of the new AI tools.
From the systems viewpoint, responsibility for the impact of technology extends beyond developers to the broader society. The user communities, including librarians providing services for academia, are considered counterparts in the effects of AI technology systems. Individuals decide how they behave with the new information technology, for example, whether they trust the system and its outcome. Thus, an individual user is also part of the socio-technical evolution of building transparent, accountable, and explainable AI.
In this study, we explore the challenges of adopting AI tools in scientific research on the level of an individual librarian working for academia. We aim to detect poorly addressed mindsets around explainability, fairness, and privacy, named “blind spots” in AI ethics (Hagendorff, 2022). The goal is to understand the “determinants” of librarians’ information behavior with novel AI tools. We focus on two AI-powered visual discovery services: openknowledgemaps.org and www.litmaps.com. These tools help users to navigate and analyze research articles as concept graphs.
In this poster, our primary research question is: What are the determinants of librarians’ intentions when they adopt/use new AI-powered tools?
We conducted an expert evaluation (Tessmer, 1993) on these two discovery services using the Theory of Planned Behavior (TPB) as a theoretical framework that explains human behavior through three individual beliefs: attitudes, norms, and control. This framework helped us detect new “blind spots” in the behavioral determinants that have remained unnoticed in the recent discourses about AI ethics in libraries.
Our study indicated a lack in the area of normative beliefs, a “blind spot”: The social pressure to quickly adopt the newest technology and the lack of library-specific norms for using AI in academia may become a handicap for an individual librarian who contemplates whether or not to use an AI tool.
State of Open Data 2023
Authors: Oefelein Timon 
Published: November 2023

The annual State of Open Data survey is a global and collaborative initiative aimed at understanding the dynamics of open data within the research community across different disciplines and regions. It seeks to uncover researchers' perspectives, behaviours, and the impact of data management on their work, ultimately contributing to the development of more effective data sharing practices that align with the evolving needs of the research community.
Now in its eighth year, the 2023 survey findings, presented in this poster, shed light on the evolving landscape of research data sharing and emphasise the critical need for adaptable, nuanced approaches.
This poster will give a preview of the 2023 results, pulling out some of the main findings and analysis of year-on-year trends, with key regional differences highlighted.
One main theme to emerge is that a one size fits all approach for research data management does not work, rather there should be a move to a more nuanced strategy. Researchers across different disciplines and regions have unique needs, and their approaches to research data management vary significantly. This underscores the necessity of moving towards a more adaptable and nuanced data management strategies tailored to specific research contexts.
The State of Open Data survey is conducted in partnership with Springer Nature, Figshare and Digital Science, enhancing the survey’s reach and impact and allowing for a more comprehensive analysis of the research data landscape.

Introduction: For a long time, it was assumed that stroke only affected people aged over 60, but recent studies have shown that it can occur in younger people. In the latter group, molecular factors and inter-individual differences in susceptibility are being increasingly incriminated. The aim of our study was therefore to evaluate the haptoglobin gene polymorphism in subjects with cryptogenic ischemic stroke.
Methodology: This was a prospective case-control study and included subjects with cryptogenic ischemic stroke followed at the neurology department of FANN hospital in Senegal. Healthy controls were recruited and matched with the cases according to sex and age ±2 years. The Hp gene polymorphism was determined using conventional PCR without enzymatic digestion and biochemical parameters were assayed using the Architect ci4100 system (Abott, USA).
Results: Our study included 35 patients with cryptogenic stroke. The mean age of the patients was 45±11 years and the sex ratio was 1:1. Assessment of cardiovascular risk factors showed a high frequency of hypertension (46.57%) followed by dyslipidemia (21.42%) and diabetes (10.71%). Drug use was found in 7.14% of subjects. With regard to haptoglobin genotypes, Hp2-2 was much more prevalent in stroke patients (21.42%) than in control subjects (14.28%). In contrast, the Hp1-1 genotype was more prevalent in control subjects, with a rate of 57.14%, compared with 39.28% for cryptogenic strokes.
Conclusion: Our results seem to show that the Hp2-2 genotype is involved in the occurrence of cryptogenic ischemic stroke. However, the impact of these parameters must be assessed in conjunction with other associated cardiovascular risk factors.
The production of a glass toggle
Authors: Ellis Clare , Bertini Martina , Sykes Dan 
Published: November 2023

A glass toggle was found among the ashes of a domestic hearth during the excavation of an unenclosed Iron Age settlement at Kilninian, Isle of Mull, Argyll, Scotland. The hearth was radiocarbon dated to 168 cal bc–cal ad 3 (SUERC-46765). The toggle was covered with a black residue that was stuck to its surface and it looked hastily made, using low-quality aqua cullet. Chemical analyses, using LA-ICP-MS, indicate the glass used was a natron-based glass. The trace element composition suggested the glass was produced in the east Mediterranean area using coastal sands and had subsequently been recycled. The morphological examination using extended depth of field microscopy and micro-computed tomography revealed the toggle was shaped at low temperatures using contaminated glass. The black sooty residue found on the surface of the toggle was found to extend within the toggle and was fused with the object. This could only have happened during manufacture, when the glass was still hot enough to be malleable and stick to the contamination. The uncleaned residues on the surface and the presence of the unpolished pontil scar suggest the toggle may have fallen in the hearth during manufacture and was lost to its maker. Analyses of other glass toggles found in Scotland and Ireland confirmed that natron-based glass had also been used and the toggles were made in the same way as that from Kilninian.

The Preacher Stone in the Bathgate Hills
Authors: Small Alastair , Small Carola 
Published: November 2023

The Preacher Stone is a natural boulder in the Bathgate Hills which is inscribed with a text recording a sermon preached on 14 January 1738 by ‘the worthy Mr Hunter’. This was an event of some significance in the early development of the Secession Church. The stone has not hitherto been the subject of a detailed study, and the various published references to it are incorrect or defective in some respect. In this article we give an accurate account of the stone and its environs, we comment on the letterforms which were intended to add dignity to the inscription, and we explain the importance of John Hunter in the context of the newly developing Secession. We draw on the unpublished Minutes of the Associate Presbytery and of the Session of the Craigmailen congregation to correct some of the misunderstandings that have arisen about the place and date of the event it records, and maintain the veracity of the inscribed text.

The origin of the Portuguese Drummonds
Authors: Sykes Jonathan J F 
Published: November 2023

This paper explores the origin of the Drummond surname in the Portuguese archipelago of Madeira. Used by Portuguese subjects from the early 16th century, the name is claimed to derive from João Escórcio (‘John the Scot’ or ‘Scottish John’), a settler of the 15th century. The first aim of this paper is to provide an initial analysis of Escórcio’s existence in the record of the Council of Funchal, between 1470 and 1486, to contextualise his emergence in Portugal’s first Atlantic colony. As part of this approach, the historiography of Scottish migration is engaged with drawing upon examples of Scots overseas.
The secondary purpose of this paper is to present the correspondence between Escórcio’s descendants, the Chiefs of the Clan Drummond and their kinsmen in Scotland, spanning the 16th to 18th centuries, to complement the chronology of Escórcio in Madeira. This same correspondence reconciles his identity with that of John Drummond, considered a son of Sir John Drummond of Stobhall and Cargill and Lady Elizabeth Sinclair, and reveals a tie of kinship between the Portuguese Drummonds and their Scottish namesakes. Through the research presented, currently Escórcio could be considered the earliest known example of a Scottish settler in Portuguese history, written into the historical record of the Clan Drummond. As a result, this paper may be considered a contribution to the study of Scottish migration within the Iberian world during the late medieval period, a field that is largely unknown.

ImportanceGood-quality parent-infant interactions have protective effects on infant socio-emotional and behavioral development. These interactions are especially critical for very preterm infants at risk of vulnerabilities related to immaturity. Skin-to-skin contact (SSC) has been found to improve mother–preterm infant interaction behaviors, but few studies exist regarding its benefits when initiated immediately after birth.ObjectiveTo determine the effect of immediate SSC at birth for very preterm infants on mother-infant interaction quality at 4 months of corrected age.Design, Setting, and ParticipantsThis secondary analysis used data from the Immediate Parent-Infant Skin-to-Skin Study (IPISTOSS), a randomized clinical trial conducted between April 1, 2018, and June 30, 2021, at 3 neonatal units in Sweden and Norway. Participants included very preterm infants (28-33 gestational weeks of age) and their parents. Four-month follow-up was concluded in December 2021. Data analyses were performed on March 16 and September 18, 2023.InterventionInfants were allocated to standard incubator care or SSC with either parent initiated at birth and continued throughout the first 6 hours after birth.Main Outcomes and MeasuresThe primary outcome was mother-infant interaction quality as measured with the Parent–Child Early Relational Assessment (PCERA), based on video recordings of a 5-minute free-play situation with mother-infant dyads at 4 months of corrected age. A multilevel regression analysis was performed.ResultsThis analysis included 71 infants (31 twins [44%]) and 56 mothers. Infants had a mean (SD) gestational age of 31 weeks 3 (1.3) days, and more than half were male (42 [59%]); mothers had a mean (SD) age of 32 (4.9) years. There were 37 infants allocated to standard care and 34 to SSC with either parent after birth. During the first 6 hours after birth, fathers provided more SSC than mothers, with a median (IQR) of 3.25 (2.25-4.5) and 0.75 (0-2.5) hours, respectively. A statistically significant difference in 1 of 5 PCERA subscales (subscale 3: infant positive affect, communicative and social skills) was observed, with higher-quality mother-infant interaction in the SSC group at 4 months (Cohen d = 0.67 [95% CI, 0.17 to 1.17]; P = .01). This effect remained significant when adjusting for primiparity, child sex, and observation setting.Conclusions and RelevanceIn this study of the effect of immediate parent-infant SSC after very preterm birth, SSC was beneficial for the mother-infant relationship. These findings suggest that immediate SSC should be supported in the clinical setting.Trial RegistrationClinicalTrials.gov Identifier: NCT03521310

Published: November 2023

ImportanceThe understanding of the association between KRAS sequence variation status and clinical outcomes in colorectal cancer (CRC) has evolved over time.ObjectiveTo characterize the association of age at onset, tumor sidedness, and KRAS sequence variation with survival among patients diagnosed with CRC.Design, Setting, and ParticipantsThis cross-sectional study used data extracted from the Surveillance, Epidemiology, and End Results database. Patients diagnosed with adenocarcinoma of the colon or rectum from 2010 through 2015 were included and were classified as having young-onset (YO) cancer if diagnosed between ages 20 to 49 years and late-onset (LO) cancer if diagnosed at age 50 years or older. Data were analyzed from April 2021 through August 2023.Main Outcomes and MeasuresCRC cause-specific survival (CSS) was summarized using Fine and Gray cumulative incidence and Kaplan-Meier curves. Estimation of subdistribution hazard ratios (sHRs) for the association of KRAS status, age at onset, and tumor location with CRC CSS was conducted using the Fine and Gray competing risk model. Cox proportional hazards regression was used to estimate and compare HRs.ResultsAmong 21 661 patients with KRAS sequence variation status (mean [SD] age at diagnosis, 62.50 [13.78] years; 9784 females [45.2%]), 3842 patients had YO CRC, including 1546 patients with KRAS variants, and 17 819 patients had LO CRC, including 7311 patients with KRAS variants. There was a significant difference in median CSS time between patients with variant vs wild-type KRAS (YO: 3.0 years [95% CI, 2.8-3.3 years] vs 3.5 years [95% CI, 3.3-3.9 years]; P = .02; LO: 2.5 years [95% CI, 2.4-2.7 years] vs 3.4 years [95% CI, 3.3-3.6 years]; P &amp;lt; .001). Tumors with variant compared with wild-type KRAS were associated with higher risk of CRC-related death (YO: sHR, 1.09 [95% CI, 1.01-1.18]; P = .03; LO: sHR, 1.06 [95% CI, 1.02-1.09]; P = .002). Among patients with YO cancer, mortality hazards increased by location, from right (sHR, 1.02 [95% CI, 0.88-1.17) to left (sHR, 1.15 [95% CI, 1.02-1.29) and rectum (sHR, 1.16 [95% CI, 0.99-1.36), but no trend by tumor location was seen for LO cancer.Conclusions and RelevanceIn this study of patients diagnosed with CRC, KRAS sequence variation was associated with increased mortality among patients with YO and LO tumors. In YO cancer, variant KRAS–associated mortality risk was higher in distal tumors than proximal tumors.

AbstractA cobalt‐catalyzed intermolecular 1,2‐difunctionalization of alkenes with anilines/indoles and acetonitrile has been developed. This protocol provides an access to functionalized cyano‐containing molecules. In this transformation, employing di‐tert‐butyl peroxide as a radical initiator, a variety of commercialized nucleophiles and electronically diverse arenes were well tolerated. In addition, we also studied the kinetic isotope effect.
[3+2] Cycloaddition of Rationally Designed Trisubstituted Cyclic α‐Chloroamide: an Alternative Strategy for Accessing Spirocyclic γ‐Lactam Architecture

Published: November 2023

AbstractHere we present a [3+2] cycloaddition of rationally designed trisubstituted cyclic α‐chloroamides, primarily those incorporating pharmacological pyrazolone cores, as potent synthons for synthesizing valuable spirocyclic γ‐lactam architectures. This protocol exhibits 52–96% yields, impressive substrate compatibility, and scale‐up capacity. Importantly, this study also represents one of the rare examples that harness enaminone C−N bond cleavage to engineer relevant spirocyclic γ‐lactam skeletons of biological interest. Moreover, we propose a plausible mechanistic explanation to elucidate the outstanding chemical outcomes observed, thereby enriching the synthetic toolbox for pyrazolone chemistry and α‐haloamide‐mediated reactions.
