"While many accept that math is a universal, culturally indifferent subject in school, this book demonstrates that this is anything but true. Building off of a historically conscious understanding of school reform, Diaz makes the case that the language of mathematics, and the symbols through which it is communicated, is not merely about the alleged cultural indifference of mathematical thinking; rather, mathematical teaching relates to historical, cultural, political, and social understandings of equality that order who the child is and should be. Focusing on elementary math for all education reforms in America since the mid-twentieth century, Diaz offers an alternative way of thinking about the subject that recognizes the historical making of contemporary notions of inequality and difference.

The purpose of this article is to present the use of photography as a supplement to a classic grounded theory research study with lesbian women regarding their experience of identity, culture, and oppression. Photography was integrated into the grounded theory methodology to visually express the theoretical codes that emerged from the grounded theory of liberated identity. Photographs are presented with coded substages and participant in vivo codes, including explanations of the visual representation in the photographs. The findings, the basic social process substage photographs, were guided by the participants to best convey visual meaning of their experience. The photographic images reveal how the use of photography, in concert with Glaserian grounded theory, exemplified experience, humanity, and meaning in this specific research study, and thus the complementary visual image can edify the significance in the humanness and affectivity of research participants.
Examines whether racial & ethnic groups vary in their job-search strategies & whether the effects of job-search strategies vary for racial & ethnic groups, using data from the Multi-City Study of Urban Inequality, which includes a random sample of households in Atlanta ([GA] N = 1,528), Boston ([MA] N = 1,820), & Los Angeles ([CA] N = approximately 4,000). Findings indicate that Hispanics rely much more heavily on informal search strategies, but these lead to lower-paying jobs. Relying on a friend or relative to locate a job is especially detrimental for Hispanics. Using a multiplex tie (ie, a person who is a friend or relative, a coworker, & a neighbor) leads to lower-paying jobs for blacks & higher-paying jobs for whites. Results suggest that a better understanding of racial & ethnic differences in search strategy results may require a more detailed examination of racial & ethnic differences in the kinds of jobs produced by informal searches & the types of employers more likely to use word-of-mouth recruitment. 6 Tables, 25 References.

Intrinsically disordered proteins (IDPs) are abundant in complex organisms. Due to their promiscuous nature and their ability to adopt several conformations IDPs constitute important points of network regulation. The family of Brain Expressed and X-linked (Bex) proteins consists of 5 members in humans (Bex1-5). Recent reports have implicated Bex proteins in transcriptional regulation and signaling pathways involved in neurodegeneration, cancer, cell cycle and tumor growth. However, structural and biophysical data for this protein family is almost non-existent. We used bioinformatics analyses to show that Bex proteins contain long regions of intrinsic disorder which are conserved across all members. Moreover, we confirmed the intrinsic disorder by circular dichroism spectroscopy of Bex1 after expression and purification in E. coli. These observations strongly suggest that Bex proteins constitute a new group of IDPs. Based on these findings, together with the demonstrated promiscuity of Bex proteins and their involvement in different signaling pathways, we propose that Bex family members play important roles in the formation of protein network hubs. ; Ministry of Economy and Competitiveness (MINECO) from the Government of Spain.

A theory-based systems approach, such as AcciMap accident analysis, has been widely used over the years in multiple safety critical sectors such as the nuclear, petrochemical, aviation and railway industries to provide a detailed understanding of complex systems and the chain of events contributing to accidents resulting from system failure. However, despite its advantages, the use of a systems approach in the food safety context has to date been limited. The purpose of this study was to investigate three established norovirus incidents using the AcciMap accident analysis approach to determine its efficacy at informing the design of food safety policies following a norovirus outbreak to prevent reoccurrence. This approach was found to be of value in analysing norovirus outbreaks. The findings of the AcciMap analysis reveal the norovirus outbreaks were not the outcome of a single causal incident, but a chain of events and interactions that involved governmental failure to control and enforce safety regulations and the impact on managerial and individual behaviours at a lower level in the system. The analysis identified the common contributory factors such as poor inspections, lack of regular monitoring of quality of water supply, inadequate management of wastewater and ineffective communication that led to each incident across the hierarchical levels within a sociotechnical system. The value of using the AcciMap approach is that it does not constrain the analysis to individual components or particular types of incident, allowing for a more holistic and interconnected risk assessment.

A systems-based approach can assist the response to complex safety-related issues by taking both human factors and organisational aspects into consideration. Systems-based approaches, such as AcciMap, have been used in a wide variety of domains to investigate why a food safety incident occurs (e.g. bovine spongiform encephalopathy (BSE) in the UK). Moreover, other water- and foodborne outbreaks have been investigated using this approach. Norovirus is the most common cause of viral acute gastroenteritis outbreaks worldwide, associated with international hospitality settings such as hotels. With an estimated 685 million episodes and 210,000 deaths worldwide every year, this is a significant global socioeconomic and public health concern. A systems-based approach allows in-depth analysis of the system in which an issue occurs, providing insights into the errors or chain of events causing the accident. However, there is limited literature on food safety incident analysis using such approaches. This study aims to provide a stronger theoretical knowledge base of the subject and enhance understanding of the contributory factors leading to norovirus outbreaks to prevent future ocurrence. This research applied an AcciMap approach to analyse and graphically represent the contributing factors and interactions between different levels. The findings of the AcciMap analysis revealed that factors such as communication issues, managerial flaws in water systems management and public health regulations were common systemic failures at the government and physical/individual levels in the three analysed outbreaks. Thus, norovirus outbreaks were not the outcome of a single causal factor but a chain of events and interactions that occurred across a complex system.
AbstractResearch on vegetable-based protein sources has grown as a result of the European Union ban on the inclusion of meat and bone meal in diets of agricultural livestock. This together with recent concern over genetically modified soybeans, the protein source of choice for monogastric diets, has sparked research into the identification of some alternative protein sources. The objective of this study was to evaluate the effect of raw or extruded pea (RP and EP), faba beans (RFb and EFb) or lupin (RL and EL) in partial substitution of soybean meal and other starch sources in broiler diets. A total of 462-d-old male Ross chicks, Marek vaccinated, were randomly assigned to seven dietary treatments (3 pens/treatment). Chicks were floor housed, ad libitum fed isocaloric and isonitrogenous diets and had free access to water. Artificial light was provided 10 h/d. The amount of alternative proteins used as fed basis and for 1-10 d-old and 11-42 d-old growing periods were: RP and EP: 350 g/kg for all diets; RFb.
Purpose The hospitality sector underpins the Dominican Republic's (DR) economy but may be a setting where foodborne disease outbreaks (FBDOs) can occur. The purpose of this research is to conduct a systematic mapping exercise on the available scientific literature related to FBDOs in hospitality in the DR and their link to reported food safety and hygienic practices. Design/methodology/approach A predefined search protocol applied the principles of PRISMA guidance. Publications (n = 2,793) from databases (e.g. Web of Science, PubMed) were identified and systematically selected for relevance. A full-text assessment based on the inclusion criteria led to the identification of a refined list of studies and academic publications (n = 22) included in this review. The descriptive analysis of the collated data is then presented graphically. Findings A low rate of reporting highlights a knowledge gap on FBDOs, the related food safety hazards and how they are mitigated by stakeholders and local health authorities in the DR. Improving government and other stakeholder capacity to report, investigate and understand FBDOs and the practices involved is essential. Research limitations/implications The research has implications for Government, businesses and public health officials and managers in the hospitality sector in the DR. A potential research limitation is that the search strategies could miss some relevant articles. Practical implications The findings provide a framing for improved risk analysis in implementing food safety management strategies for FBDOs. Originality/value To the best of the authors' knowledge, this is the first systematic mapping research assessing evidence of FBDOs affecting hospitality in the DR.

We review the literature that identifies selection bias in media-based data & propose a theoretical model of the sources of these biases. Given the implications for validity & reliability, we conclude that newspaper data often do not reach acceptable standards for event analysis & that using them can distort findings & misguide theorizing. Furthermore, media selection biases are resistant to correction procedures largely because they are unstable across media sources, time, & location. We end with a plea for more circumspect approaches to media data that fully & openly consider the implications of their inherent limitations. Tables, Figures, References.

Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.
Background: Achieving universal health coverage (UHC) involves all people receiving the health services they need, of high quality, without experiencing financial hardship. Making progress towards UHC is a policy priority for both countries and global institutions, as highlighted by the agenda of the UN Sustainable Development Goals (SDGs) and WHO's Thirteenth General Programme of Work (GPW13). Measuring effective coverage at the health-system level is important for understanding whether health services are aligned with countries' health profiles and are of sufficient quality to produce health gains for populations of all ages. Methods: Based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we assessed UHC effective coverage for 204 countries and territories from 1990 to 2019. Drawing from a measurement framework developed through WHO's GPW13 consultation, we mapped 23 effective coverage indicators to a matrix representing health service types (eg, promotion, prevention, and treatment) and five population-age groups spanning from reproductive and newborn to older adults (≥65 years). Effective coverage indicators were based on intervention coverage or outcome-based measures such as mortality-to-incidence ratios to approximate access to quality care; outcome-based measures were transformed to values on a scale of 0–100 based on the 2·5th and 97·5th percentile of location-year values. We constructed the UHC effective coverage index by weighting each effective coverage indicator relative to its associated potential health gains, as measured by disability-adjusted life-years for each location-year and population-age group. For three tests of validity (content, known-groups, and convergent), UHC effective coverage index performance was generally better than that of other UHC service coverage indices from WHO (ie, the current metric for SDG indicator 3.8.1 on UHC service coverage), the World Bank, and GBD 2017. We quantified frontiers of UHC effective coverage performance on the basis of pooled health spending per capita, representing UHC effective coverage index levels achieved in 2019 relative to country-level government health spending, prepaid private expenditures, and development assistance for health. To assess current trajectories towards the GPW13 UHC billion target—1 billion more people benefiting from UHC by 2023—we estimated additional population equivalents with UHC effective coverage from 2018 to 2023. Findings: Globally, performance on the UHC effective coverage index improved from 45·8 (95% uncertainty interval 44·2–47·5) in 1990 to 60·3 (58·7–61·9) in 2019, yet country-level UHC effective coverage in 2019 still spanned from 95 or higher in Japan and Iceland to lower than 25 in Somalia and the Central African Republic. Since 2010, sub-Saharan Africa showed accelerated gains on the UHC effective coverage index (at an average increase of 2·6% [1·9–3·3] per year up to 2019); by contrast, most other GBD super-regions had slowed rates of progress in 2010–2019 relative to 1990–2010. Many countries showed lagging performance on effective coverage indicators for non-communicable diseases relative to those for communicable diseases and maternal and child health, despite non-communicable diseases accounting for a greater proportion of potential health gains in 2019, suggesting that many health systems are not keeping pace with the rising non-communicable disease burden and associated population health needs. In 2019, the UHC effective coverage index was associated with pooled health spending per capita (r=0·79), although countries across the development spectrum had much lower UHC effective coverage than is potentially achievable relative to their health spending. Under maximum efficiency of translating health spending into UHC effective coverage performance, countries would need to reach $1398 pooled health spending per capita (US$ adjusted for purchasing power parity) in order to achieve 80 on the UHC effective coverage index. From 2018 to 2023, an estimated 388·9 million (358·6–421·3) more population equivalents would have UHC effective coverage, falling well short of the GPW13 target of 1 billion more people benefiting from UHC during this time. Current projections point to an estimated 3·1 billion (3·0–3·2) population equivalents still lacking UHC effective coverage in 2023, with nearly a third (968·1 million [903·5–1040·3]) residing in south Asia. Interpretation: The present study demonstrates the utility of measuring effective coverage and its role in supporting improved health outcomes for all people—the ultimate goal of UHC and its achievement. Global ambitions to accelerate progress on UHC service coverage are increasingly unlikely unless concerted action on non-communicable diseases occurs and countries can better translate health spending into improved performance. Focusing on effective coverage and accounting for the world's evolving health needs lays the groundwork for better understanding how close—or how far—all populations are in benefiting from UHC.
