An Analysis of the news coverage of Fintech in Africa: a natural language processing approach

Abstract

This study analyzes a corpus of 2,409 English-language news articles published between 2013 and 2023, focusing on the Fintech sector in Africa, using Natural Language Processing (NLP) techniques. The research aims to uncover the dominant themes, narratives, and trends in media coverage of African Fintech, enriching the understanding of how the sector is represented. The analysis reveals a significant increase in Fintech-related news coverage over the decade, with a marked rise post-2020, reflecting a burgeoning industry. Text mining methods, including word cloud visualization, geographical mention analysis, sentiment analysis, and topic modelling, are applied to extract insights from the data. The study contributes to the understanding of media’s role in shaping perceptions of the African Fintech sector and provides valuable insights for stakeholders in policymaking, investment, and technology development.

Phosphorylation of endothelial histone H3.3 serine 31 by PKN1 links flow-induced signaling to proatherogenic gene expression

Abstract

Atherosclerotic lesions develop preferentially in arterial regions exposed to disturbed blood flow, where endothelial cells acquire an inflammatory phenotype. How disturbed flow induces endothelial cell inflammation is incompletely understood. Here we show that histone H3.3 phosphorylation at serine 31 (H3.3S31) regulates disturbed-flow-induced endothelial inflammation by allowing rapid induction of FOS and FOSB, required for inflammatory gene expression. We identified protein kinase N1 (PKN1) as the kinase responsible for disturbed-flow-induced H3.3S31 phosphorylation. Disturbed flow activates PKN1 in an integrin α5β1-dependent manner and induces its translocation into the nucleus, and PKN1 is also involved in the phosphorylation of the AP-1 transcription factor JUN. Mice with endothelium-specific PKN1 loss or endothelial expression of S31 phosphorylation-deficient H.3.3 mutants show reduced endothelial inflammation and disturbed-flow-induced vascular remodeling in vitro and in vivo. Together, we identified a pathway whereby disturbed flow through PKN1-mediated histone phosphorylation and FOS/FOSB induction promotes inflammatory gene expression and vascular inflammation.

Uncertainty maps for model-based global climate classification systems

Abstract

Climate classification systems (CCSs) are emerging as essential tools in climate change science for mitigation and adaptation. However, their limitations are often misunderstood by non-specialists. This situation is especially acute when the CCSs are derived from Global Climate Model outputs (GCMs). We present a set of uncertainty maps of four widely used schemes -Whittaker-Ricklefs, Holdridge, Thornthwaite-Feddema and Köppen- for present (1980–2014) and future (2015–2100) climate based on 52 models from the Coupled Intercomparison Model Project Phase six (CMIP6). Together with the classification maps, the uncertainty maps provide essential guidance on where the models perform within limits, and where sources of error lie. We share a digital resource that can be readily and freely integrated into mitigation and adaptation studies and which is helpful for scientists and practitioners using climate classifications, minimizing the risk of pitfalls or unsubstantiated conclusions.

A modified transformer model for the extended-range forecast of intraseasonal oscillation

Abstract

Extended-range forecast has long maintained a difficult point for the seamless forecast system due to the lack of predictability, with intraseasonal oscillation (ISO), an important signal in many high-impact weather events, being an important source of that. To improve the accuracy of ISO extended-range forecast and make up the gaps in previous researches in this regard, a data-driven model ISOX is proposed for the intraseasonal components of atmospheric fields. Compared with the subseasonal forecast results from climate forecast system (CFS), and the climatological forecast, ISOX achieves higher accuracy for lead times longer than 13 days, with few spatial or temporal weak points. It also performed better in predicting the positive 2 m temperature ISO and lower tropospheric conditions in a heatwave event, surpassing CFS for lead times longer than 13 days. Finally, through gradient evaluation, the model is proved to be able to study the ISO signal movements of atmospheric systems. Thus, the success of this model may shed light on improving extended-range forecast skills and assist the timely detection and prevention of possible meteorological disasters.

Assessing the impact of climate change on rainfall-triggered landslides: a case study in California

Abstract

Landslides are widespread natural hazards which take a heavy toll on lives, property, and infrastructure each year. In January 2023 and 2024, widespread landslides occurred in California as a result of extreme winter precipitation. Estimating the regional evolution of landslide hazard in a changing climate is essential for adaptation planning and risk mitigation efforts. The complex effects of climate change on landslide hazard, however, are poorly understood. Here, we use climate and landslide observations to develop a novel data-driven approach for landslide susceptibility assessment under historical and future climate conditions. We apply this framework to investigate the evolution of landslide susceptibility in California and its impacts on the roadway system based on downscaled climate projections under moderate and high greenhouse gas emission scenarios. On average, the results indicate an increase in landslide susceptibility through 2100 in regions where historical susceptibility is moderate to very high. Although the spatio-temporal variations in landslide susceptibility are sensitive to climate model uncertainties in predicting extreme rainfall, the direst impacts are largely circumvented in lower emission scenarios.

SESTA/FOSTA as de Facto Hate Policy: Combatting Carceral Investments and Uplifting Community-Based Solutions

Abstract

Introduction

Sex workers overlap demographically with individuals who are pushed into informal economies due to their marginalized identities. Although policies increasing the criminalization of sex work are not regarded as hate politics, we argue that these policies are de facto hate policies against LGBTQ + communities and other marginalized groups.

Methods

We utilize a literature review of nine empirical studies (2018–2023) on the effects of SESTA/FOSTA, a sex worker hate policy, as well as 25 interviews from a 2022 community-based study on the effects of California Senate Bill 233 (SB233), which decriminalized condom possession.

Results

SESTA/FOSTA harmed sex workers by reducing their income, restricting access to safety and screening resources, increasing the risk of exploitation and violence, and removing online spaces for community building and political organizing. Moreover, marginalized sex workers felt these effects most keenly. The SB233 interviews further revealed that condom possession was utilized as a means for law enforcement to harass trans women through pervasive harassment, deadnaming, and forcing sexual encounters with the threat of violence and jail time.

Conclusions

SESTA/FOSTA reveals how policies increasing the criminalization of sex workers also hate policies against marginalized groups. However, policies reducing the criminalization of sex workers, such as SB233, may be ineffective without community involvement. For this reason, we recommend community-based policies like SB357, which repealed loitering with intent.

Policy Implications

Hate politics increase carceral investments, leading to police harassment and surveillance of marginalized groups. We recommend community-led policy suggestions as an alternative.

Gender and Sexual Orientation in Canadian Intimate Partner Violence Research: A Focused Mapping Review and Synthesis

Abstract

Introduction

Intimate partner violence (IPV) is a widespread social and health problem disproportionately burdening women and, we are learning, gender and sexual minority (GSM) people, who are under-represented in research. The measurement and reporting of gender and sexual orientation in health and social science research are also inadequate.

Methods

We conducted a focused mapping review and synthesis to examine the inclusion of GSM people, and the reporting of gender identity and sexual orientation, in Canadian IPV research. Using database searches, hand-searches (November 2022), and citation chaining (April/May 2023), we identified eligible articles that (1) were published in English or French in peer-reviewed journals from 2020 to 2022, (2) reported research involving at least some Canadian IPV survivors and/or perpetrators, and (3) had at least one Canada-affiliated author.

Results

The 150 included articles contribute significantly to the IPV literature but have shortcomings. Most articles inadequately reported gender identity and sexual orientation; among articles reporting, most only included cisgender heterosexual participants. Some articles conflated sex and gender, used outdated terminology, or used language that invisibilized GSM people.

Conclusions

While research focused on heterosexual women (and men) is needed, exclusionary research practices can further marginalize GSM people.

Policy Implications

Given such research practices can impede the development of equity-oriented policies for these groups, we provide recommendations for researchers to improve inclusion and reporting. Gatekeepers such as ethics review board members and funders should strive to uphold these standards, including developing their own research and reporting policies.

Innovations that helped with accessing and delivering primary care for infants and young children during COVID-19

Abstract

Background

For children under age six, regular preventative primary care is needed for administration of vaccinations, surveillance of development, and early diagnosis and intervention for any potential health conditions or developmental delays. The COVID-19 pandemic created many barriers to providing and accessing primary care. While many studies have explored these barriers, it is important to understand how primary care adapted to ensure these crucial early-years appointments were not missed throughout the pandemic. The objective of this study, therefore, was to discover innovative programs or services that were used, and suggestions for programs or services that could have been implemented, to facilitate delivery of, and access to, primary care for young children during the COVID-19 pandemic (March 2020-May 2023).

Methods

This qualitative descriptive study used a survey and semi-structured interviews to discuss primary care programs or services with parents or caregivers of children who were under the age of 6 during the pandemic and with primary care providers who deliver care to young children. The survey was sent to parent groups and primary care providers across the Canadian provinces of Ontario and Quebec from May to October 2023. Survey participants who indicated interest in further participation were subsequently contacted for an interview. Results were analyzed using content and thematic analyses.

Results

102 individuals (33 primary care providers and 69 parents or caregivers) responded to the survey and of those, 19 participated in the interviews. Six themes emerged from the innovative services or procedures that were discussed: Prioritization of young children; Creation or modification of primary care spaces; Clear decision-making guidelines; Virtual care integration; Proactive communication; and Interdisciplinary collaboration.

Conclusions

This qualitative study explored some creative and positive solutions to the struggle of providing and accessing primary care for young children during the COVID-19 pandemic. The results from this research highlight the importance of flexibility and innovation within the primary care system, especially under circumstances of sudden and unexpected increases in barriers to providing and accessing care. On-going development of innovations that improve communication, take a more collaborative approach, and adapt systems, spaces, and methods will improve primary care access and delivery.

The examination of the Multicultural Ideology Scale-revised (MCI-r) in the Canadian context

Abstract

The Multicultural Ideology Scale has been revised (MCI-r) and its psychometric properties are tested across different socio-political contexts. The MCI-r is comprised of six domains: Cultural Maintenance, Equity/Inclusion, Social Interaction, Essentialistic Boundaries, Extent of Differences, and Consequences of Diversity. This study is a part of a larger international research project, examining the validity of the MCI-r in Canada. The results of our study supported a six-factor model for the MCI-r. However, we suggest removing Essentialistic Boundaries and Extent of Differences as they do not align with multicultural ideology and affect the interpretation and application of the model. Further analyses confirmed discriminant validity for the majority of the subscales; however, ideal convergent validity was not reached for all the subscales but one (Equity/Inclusion). Sufficient reliability was established for all the subscales. The examination of the association of the six components of the MCI-r with tolerance, intergroup contact, attitudes toward different ethnocultural groups, and intercultural ideology revealed that the four subscales of Cultural Maintenance, Equity/Inclusion, Social Interaction, and Consequences of Diversity were positively related to these variables. However, the association of Essentialistic Boundaries and Extent of Differences with tolerance was negative. We further found a negative relationship between the Essentialistic Boundaries dimension and interculturalism ideology. These results further support the argument that Essentialistic Boundaries and Extent of Differences may promote fixed, essentialist views of cultural groups that contrast with the flexible, inclusive nature inherent to the principles of multiculturalism.
