Small-Scale Farmers’ Decision-Making for Crop Selection and Production Practices in Northern Haiti

Decision-making is an essential aspect of farming. The decisions farmers make affect their overall yield and, ultimately, impact their livelihoods. Understanding the different factors impacting farmer decision-making can provide insight for extension providers to improve the quality of service. In Haiti, the vast majority of farms are smallholder farms averaging less than 1.5 hectares (Ministry of Agriculture, Natural Resources, and Rural Development [MARNDR], 2010). The purpose of this study was to determine the decision-making practices of small-scale farmers in Northern Haiti related to crop production. The following research objectives guided the study: (a) identify the factors associated with crop selection, and (b) identify reasons farmers engage in specific practices for crop production. Results from this study found that small-scale farmers in the North Department reported using the following factors to determine crop selection: financial security, familial traditions, concern for family, and availability of financial resources. When determining practices for crop production, farmers relied on the following drivers: financial limitations and previous learning experiences. Recommendations include increasing the availability of resources to the farmers in this region in order to create a solid foundation for behavior adoption and increased farmer capabilities

Avoiding Pitfalls in Mammographic Interpretation

AbstractThere is a public misconception that screening mammography detects all breast malignancies. The objective of this pictorial essay is to review classic mammographic features of malignancy that, if missed, could potentially result in malpractice litigation. By identifying radiologic themes, we attempt to improve awareness about the imaging characteristics of a variety of subtle malignancies

“You Travel Faster Alone, but Further Together”: Learning From a Cross Country Research Collaboration From a British Council Newton Fund Grant

Abstract: Providing universal health coverage (UHC) through better maternal, neonatal, child and adolescent health (MNCAH) can benefit both parties through North–South research collaborations. This paper describes lessons learned from bringing together early career researchers, tutors, consultants and mentors from the United Kingdom, Kenya, and South Africa to work in multi-disciplinary teams in a capacity-building workshop in Johannesburg, co-ordinated by senior researchers from the three partner countries. We recruited early career researchers and research users from a range of sectors and institutions in the participating countries and offered networking sessions, plenary lectures, group activities and discussions. To encourage bonding and accommodate cross-cultural and cross-disciplinary partners, we asked participants to respond to questions relating to research priorities and interventions in order to allocate them into multidisciplinary and cross-country teams. A follow up meeting took place in London six months later. Over the five day initial workshop, discussions informed the development of four draft research proposals. Intellectual collaboration, friendship and respect were engendered to sustain future collaborations, and we were able to identify factors which might assist capacity-building funders and organizers in future. This was a modestly funded brief intervention, with a follow-up made possible through the careful stewardship of resources and volunteerism. Having low and middle-income countries in the driving seat was a major benefit but not without logistic and financial challenges. Lessons learned and follow-up are described along with recommendations for future funding of partnerships schemes

Thin film notch filters as platforms for biological image processing

Many image processing operations involve the modification of the spatial frequency content of images. Here we demonstrate object-plane spatial frequency filtering utilizing the angular sensitivity of a commercial spectral bandstop filter. This approach to all-optical image processing is shown to generate real-time pseudo-3D images of transparent biological and other samples, such as human cervical cancer cells. This work demonstrates the potential of non-local, non-interferometric approaches to image processing for uses in label-free biological cell imaging and dynamical monitoring.Comment: manuscript 14 pages, 5 figures, supplementary material 7 pages, 4 supplementary figure

Mothers\u27 perceptions of Melbourne InFANT Program : informing future practice

Intervention programs to prevent childhood obesity are more likely to be successful when mothers are involved and engaged. Yet programs that involve mothers do not often employ process evaluation to identify aspects of the intervention that participants enjoyed or viewed as useful. The aims of this study were to describe how participants of the Melbourne InFANT Program-an early childhood obesity prevention intervention-engaged in the program and perceived its usefulness. Process evaluation data were collected at multiple time points during and after the intervention, using mixed methods drawing upon both quantitative and qualitative data. Results from short surveys (n = 271) and interview transcripts (n = 26) revealed that the Melbourne InFANT Program was perceived as useful and relevant by most (82-93%) participants. The formats through which the knowledge and skills were delivered were considered concise and effective, and aspects considered particularly useful included group sessions and advice on practical strategies to minimize stress around mealtimes. Findings from this study are important to inform future practice and the development of interventions which are well received by participants

XPD Helicase Structures and Activities: Insights into the Cancer and Aging Phenotypes from XPD Mutations

Mutations in XPD helicase, required for nucleotide excision repair (NER) as part of the transcription/repair complex TFIIH, cause three distinct phenotypes: cancer-prone xeroderma pigmentosum (XP), or aging disorders Cockayne syndrome (CS), and trichothiodystrophy (TTD). To clarify molecular differences underlying these diseases, we determined crystal structures of the XPD catalytic core from Sulfolobus acidocaldarius and measured mutant enzyme activities. Substrate-binding grooves separate adjacent Rad51/RecA-like helicase domains (HD1, HD2) and an arch formed by 4FeS and Arch domains. XP mutations map along the HD1 ATP-binding edge and HD2 DNA-binding channel and impair helicase activity essential for NER. XP/CS mutations both impair helicase activity and likely affect HD2 functional movement. TTD mutants lose or retain helicase activity but map to sites in all four domains expected to cause framework defects impacting TFIIH integrity. These results provide a foundation for understanding disease consequences of mutations in XPD and related 4Fe-4S helicases including FancJ
