Mathematics education research on language and on communication including some distinctions: Where are we now?

Abstract

In this article, we present a narrative review of mathematics education research on language and on communication over 2019–2022, but also look ahead by addressing challenges posed by the lack of distinction between language and communication. The persistence and significance of the problem of the distinction between language and communication are thus outlined in a historical moment of celebration of growth of research in the domain. Informed by the analysis of a selection of research journal articles and by our trajectories, we discuss influential topics in the recent discourse: multilingual mathematics classrooms; mathematics teacher education on language in mathematics teaching; multimodal mathematical communication; interaction and mathematics learning; mathematical language and discourse. We connect this with new emerging or old revisited concepts: instructional designing, gesturing, argumenting and languaging. We finish by further reflecting on multimodal mathematical communication and gesturing, and on the potential of expanding the notion of mathematics register towards a notion of mathematics communication register.

Prevalence of Hypertension in Indian Tribal Population: a Systematic Review and Meta-analysis

Abstract

Hypertension is a serious condition that significantly increases the risks of several cardiovascular diseases. An estimated 1.28 billion adults aged 30–79 years worldwide have hypertension, and two-thirds of them live in low- and middle-income countries. Indigenous (tribal) populations are not exceptional to the threat of hypertension. Hence, there is a need to highlight the rising prevalence of hypertension among Indian tribes and to bring them under health care programmes. This paper reports the systematic review and meta-analysis of the literature on the prevalence of hypertension among Indian tribes by following the PRISMA guidelines. Three databases, viz. PubMed/Medline, Google Scholar and Scopus, were included. The gender-wise pooled prevalences were calculated, and forest plots were depicted. Other analyses were performed, including heterogeneity test, meta-regression and sub-group analysis. Of the 1010 studies obtained, 42 were included in this review. These studies covered tribal populations in different regions of India. The pooled prevalence of hypertension among men, women and combined were 23.66% (95% confidence interval (CI): 23.25 to 24.07%), 23.37% (95% CI: 22.99 to 23.75%) and 16.68% (95% CI: 16.10 to 17.28%) respectively. Considerable heterogeneity was found among these studies. The situation of increasing prevalence, as evident from this review, is worrisome as the hypertension epidemic will affect the poor tribal communities that cannot afford to pay for treatment expenses. Therefore, people’s access to public health services must be improved. This review discusses the recent initiatives to reduce the burden of hypertension and other noncommunicable diseases in India and highlights the need of implementation research to strengthen these initiatives.

Discrimination of Tanzanian stingless bee species (Hymenoptera, Apidae, Meliponini) based on nest characteristics

Abstract

Stingless bees are a unique resource to Afrotropical ecosystems where they pollinate crops and natural vegetation, and produce honey which has medicinal powers. Studies on African stingless bees are limited partly due to difficulties in identifying them in the field. This study aimed to explore the use of nest characteristics as a simplified technique to discriminate Tanzanian stingless bee species. A total of 49 nests belonging to eight stingless bee species were studied in 15 locations. Qualitative and quantitative data on nesting sites, nest cavities, and architecture of nest entrances, brood rearing area and food storage area were collected and analyzed by comparison of means, hierarchical clustering and principal component analysis (PCA). We found that, differences in nest characteristics among stingless bee species reflected adaptations which enhanced various functions including insulation, ventilation, defense and survival. Four of the studied species were clearly separated on the dendrogram generated by Gower’s distance and PCA plot based on quantitative data of nest architecture. Qualitative data assisted the distinction of two other species which had similar nest architecture. The findings of this study suggest that nest characteristics can facilitate identification of stingless bee species in the field. We propose the development of taxonomic tools based on key nest characteristics to provide a practical and user-friendly approach which even personnel who lack scientific expertise can use to discriminate stingless bee species. Such tools would contribute to the advancement of stingless bee management, research and extension services.

Community Resilience and Cultural Responses in Crisis: Lessons Learned from Pacific Islander Responses to the COVID-19 Pandemic in the USA

Abstract

Pacific Islander communities in the USA experienced some of the most severe effects of the COVID-19 pandemic. This qualitative synthesis examines the literature on Pacific Islander community responses and lessons learned from COVID-19, using a systematic search that identified 28 articles with this focus. Thematic analysis was subsequently used to classify both documented efforts by Pacific Islander communities to respond to the pandemic, as well as lessons learned and best practices from research in this area. Results revealed multiple efforts to address the pandemic, including Pacific Islander grassroots approaches, government responses, inter-sector collaboration, and research. Results further emphasized the importance of culturally and linguistically responsive outreach and messaging; partnership, engagement, and capacity building; and changes in research and policy approaches to promote health equity. Future efforts to address public health crises should make the most of Pacific Islander cultural approaches to disaster response. To achieve this, government and other organizations that work with PI communities need to support the development of the PI leadership, healthcare and research workforces, and work with Pacific Islander communities to build long-term, sustainable, and trustworthy partnerships.

The Moderating Role of Maternal Praise and Positivity in the Association Between Callous-Unemotional (CU) Traits and Later Aggression: A Prospective Study in Preschool Children in Colombia

Abstract

Our previous findings in the UK and Colombia show that CU traits predict later aggression specifically among children who are already aggressive. We hypothesised that this effect would be reduced in the presence of maternal praise and positivity. In a sample of 220 mothers and children from Colombia, mother–child interactions were coded for maternal praise and positivity, and mothers reported on children’s CU traits at age 3.5 and aggression at ages 3.5 and 5 years. The results show three-way interactions between CU traits, child aggression and observed parenting at age 3.5 years in the prediction of later child aggression, and two-way interactions indicating a protective effect of positive parenting in the high aggressive children. Based on our finding, it is plausible that positive parenting may modify the effect of CU traits in the highly vulnerable group of children who are already aggressive in early childhood.

Nonprofit capacity and social performance: mapping the field and future directions

Abstract

Nonprofit organizations are critical actors in the Sustainable Development Goals as they provide a wide range of social services to the community and contribute to creating a sustainable future. They must compete for funding or government contracts by showing high social performance. Among the top factors influencing social performance is capacity, and it has received considerable attention in public and nonprofit literature. Capacity refers to the resources, capabilities, and practices required to perform their functions to achieve the social mission and high social performance. However, studies concerning capacity linked with social performance remain controversial. Understanding the linkage between capacity and social performance is relevant to funders, board directors, and management as it helps them enhance organizational performance. This research aims to assess the flow of knowledge in the study field and make recommendations for future research. The study focuses on capacity of nonprofits and thoroughly reviews the literature using complementary bibliometric analysis: co-occurrence analysis of keywords, sources, and authors and bibliographic coupling analysis of documents. We conduct a systematic analysis of peer-reviewed journal articles published between 1955 and 2022. Seven significant themes emerge among the most prominent researchers: (1) the link between capacity and social performance; (2) dimensions of capacity; (3) human resource capacity linked with social performance: (4) financial capacity linked with social performance; (5) capacity building linked with social performance; (6) collaboration and capacity; and (7) factors affecting capacity–social performance. The literature on nonprofits is determined to have inconsistent findings regarding the relationship between capacity and social performance. Research on various factors influencing capacity–social performance relationships is also scarce. This article highlights major principles in the discipline and identifies significant theoretical gaps in the body of knowledge. It also outlines the conceptual foundation for the study and makes recommendations for further research. From a managerial standpoint, the study sheds light on whether capacity is linked to higher performance levels and provides policymakers with guidelines on the implications of capacity building and collaboration.

Systematic review of community engagement approach in research: describing partnership approaches, challenges and benefits

Abstract

Background

Community engagement in research has gained momentum as people have realised the importance and value it brings to research. However, a lack of standardization in the engagement approach has been reported in the literature. This systematic review aims to identify and synthesize the different engagement approaches to contextualize future implementation efforts.

Methods

The databases Patient Centred Outcomes Research Institute (PCORI), PubMed and Google Scholar were searched for English language studies published between 2008 and 2021 that focused on stakeholder involvement and phases of research engagement. Independent reviewers conducted literature search, screening, quality assessment, data extraction and analysis following previous study formats.

Results

Of the 2227 original articles retrieved, 125 were reviewed fully, of which 48 studies were included in this review. Of these 48 studies, 34 (70.8%) were health studies involving any form of engagement, while 14 (29.2%) were non-health. Most studies originated from high income countries, mainly the USA and engaged ethnic minorities, patients, disadvantaged groups and war veterans. All studies reported engagement at various levels. However, there was no standard criteria to select the type of engagement. Engagement with communities was used to develop research tools, identify research questions and harness local experiences. There were different terminologies and engagement approaches, which makes it difficult to synthesise and conceptualize the evidence.

Conclusions

Harnessing local experiences and perspectives by involving stakeholders at the earliest stage is beneficial in terms of clarifying approaches which best fits the local context. It is important to delineate between the traditional and community engagement approach.

Enhancing Symptom Screening and Patient Education Among Patients with Metastatic Lung Cancer: a Qualitative Analysis

Abstract

We explored perspectives of patients with metastatic non-small cell lung cancer (mNSCLC) on symptom screening and population-level patient-reported outcome (PRO) data regarding common symptom trajectories in the year after diagnosis. A qualitative study of patients with mNSCLC was conducted at a Canadian tertiary cancer centre. English-speaking patients diagnosed ≥ 6 months prior to study invitation were recruited, and semi-structured one-on-one interviews were conducted. Patient and treatment characteristics were obtained via chart review. Anonymized interview transcripts underwent deductive-inductive coding and thematic content analysis. Among ten participants (5 (50%) females; median (range) age, 68 (56–77) years; median (range) time since diagnosis, 28.5 (6–72) months; 6 (60%) with smoking histories), six themes were identified in total. Two themes were identified regarding symptom screening: (1) screening is useful for symptom self-monitoring and disclosure to the healthcare team, (2) screening of additional quality-of-life (QOL) domains (smoking-related stigma, sexual dysfunction, and financial toxicity) is desired. Four themes were identified regarding population-level symptom trajectory PRO data: (1) data provide reassurance and motivation to engage in symptom self-management, (2) data should be disclosed after an oncologic treatment plan is developed, (3) data should be communicated via in-person discussion with accompanying patient-education resources, and (4) communication of data should include reassurance about symptom stabilization, acknowledgement of variability in patient experience, and strategies for symptom self-management. The themes and recommendations derived from the patient experience with mNSCLC provide guidance for enhanced symptom screening and utilization of population-level symptom trajectory data for patient education.
