High-K volcanism in the Afyon region, western Turkey: from Si-oversaturated to Si-undersaturated volcanism

Volcanic rocks of the Afyon province (eastern part of western Anatolia) make up a multistage potassic and ultrapotassic alkaline series dated from 14 to 12 Ma. The early-stage Si-oversaturated volcanic rocks around the Afyon city and further southward are trachyandesitic volcanic activity (14.23 ± 0.09 Ma). Late-stage Si-undersaturated volcanism in the southernmost part of the Afyon volcanic province took place in three episodes inferred from their stratigraphic relationships and ages. Melilite– leucitites (11.50 ± 0.03 Ma), spotted rachyandesites, tephryphonolites and lamproites (11.91 ± 0.13 Ma) formed in the first episode; trachyandesites in the second episode and finally phonotephrites, phonolite, basaltic trachyandesites and nosean-bearing trachyandesites during the last episode. The parameter Q [normative q-(ne + lc + kls + ol)] of western Anatolia volcanism clearly decreased southward with time becoming zero in the time interval 10–15 Ma. The magmatism experienced a sudden change in the extent of Si saturation after 14 Ma, during late-stage volcanic activity of Afyon volcanic province at around 12 Ma, though there was some coexistence of Si-oversaturated and Si-undersaturated magmas during the whole life of Afyon volcanic province

Learning from Data Journeys

This is the final version. Available on open access from Springer via the DOI in this recordThis chapter discusses the idea of data journeys as an investigative tool and a theoretical framework for this volume and broader scholarship on data. Building on a relational and historicized understanding of data as lineages, I reflect on the methodological, conceptual and social challenges involved in mapping, analysing and comparing the production, movement and use of data within and across research fields - and some of the strategies developed to cope with such difficulties. I then provide an overview of the significant variation among the data practices garnered in this volume. Specific nodes of difference and similarity across data journeys are identified, while also emphasising the extent to which such commonalities are dependent on specific situations of inquiry. In closing, I highlight the significance of this approach towards addressing concerns raised by data-centric science and the emergence of big and open data.European CommissionAlan Turing Institut

Exploring women and traditional birth attendants\u27 perceptions and experiences of stillbirths in district Thatta, Sindh, Pakistan: A qualitative study

Background: Pakistan reports the highest stillbirth rate in the world at 43 per thousand births with more than three-quarters occurring in rural areas. The Global Network for Women\u27s and Children\u27s Health maintains a Maternal and Newborn Health Registry (MNHR) in 14 study clusters of district Thatta, Sindh Pakistan. For the last 10 years, the MNHR has recorded a high stillbirths rate with a slow decline. This exploratory study was designed to understand the perspectives of women and traditional birth attendants regarding the high occurrence of stillbirth in Thatta district.Methods: We used an exploratory qualitative study design by conducting in-depth interviews (IDIs) and focus group discussions (FGDs) using semi-structured interview guide with rural women (FGDs = 4; n = 29) and traditional birth attendants (FGDs = 4; n = 14) who were permanent residents of Thatta. In addition, in-depth interviews were conducted with women who had experienced a stillbirth (IDIs = 4). This study presents perceptions and experiences of women and TBAs regarding high rate of stillbirth in Thatta district, Karachi.Results: Women showed reluctance to receive skilled/ standard care when in need due to apprehensions towards operative delivery, poor attitude of skilled health care providers, and poor quality of care as service delivery factors. High cost of care, far distance to facility, lack of transport and need of an escort from the family or village to visit a health facility were additional important factors for not seeking care resulting in stillbirth. The easy availability of unskilled provider in the form of traditional birth attendant is then preferred over a skilled health care provider. TBAs shared their husband or family members restrict them to visit or consult a doctor during pregnancy. According to TBAs after delivering a macerated fetus, women are given herbs to remove infection from woman\u27s body and uterus. Further women are advised to conceive soon so that they get rid of infections.Conclusion: Women of this rural community carry lots of apprehension against skilled medical care and as a result follow traditional practices. Conscious efforts are required to increase the awareness of women to develop positive health seeking behavior during pregnancy, delivery and the post-partum period. Alongside, provision of respectful maternity care needs to be emphasized especially at public health facilities

Not AvailableThe fall army worm (FAW) Spodoptera frugiperda (J.E. Smith) is an invasive pest native to Americas, and it has recently been observed invasive to India. The mtCOI based analysis of the populations of FAW from the Americas showed the prevalence of two strains viz. R (Rice) and C (Corn). Recent studies on FAW populations from Africa revealed the predominance of R strain that feed primarily on maize. To understand the prevalence of strain and molecular diversity of FAW in India, studies were made on the populations collected on maize, sweet corn, and sorghum from six states of India (Karnataka, Tamil Nadu, Andhra Pradesh, Telangana, Madhya Pradesh and Maharashtra). The results reveal that this is the first report of the occurrence of FAW from Andhra Pradesh, Madhya Pradesh, Maharashtra, Tamil Nadu and Telangana. Further, mtCOI (5') based sequence analyses revealed that these populations from India aligned with R strain with minimal genetic diversity exhibiting no host/ location specific variations. FAW populations in India primarily feed on maize as observed in Africa with no incidence on rice yet. The present study suggests a possible invasion by single genetic stock of FAW in India which requires haplotype analysis.Not Availabl
