How Much is E-Commerce Worth to Rural Businesses?

The probability of a business paying for an e-commerce presence ultimately depends on demographic features, experiences with e-commerce, technological expertise, and knowledge of e-commerce opportunities and limitations. Results allow for the assignment of probabilities associated with various business profiles to determine the willingness to pay for an e-commerce presence.Research and Development/Tech Change/Emerging Technologies,

What Kind of Social Policy do Social Work Students Prefer? A Comparison of Students in Three Countries

The goal of this article is to contribute to our understanding of the way in which students at the very beginning of their social work training view the sources of social problems and the way in which society should deal with these problems. This is part of an effort to determine the contemporary role of social change in the thinking of social workers in different national settings. Traditionally, social work has regarded social change as one of its primary professional objectives. Ever since the settlement houses were first established in the late years of the 19th century, many social workers have indeed been actively involved in social action aimed at bringing about social reform for the betterment of deprived segments of society. These efforts first took place in a period during which the term welfare state had yet to be coined and the notion of state responsibility for social protection for the poor was not widely accepted. Nevertheless, the conviction of these early social workers that social conditions were the prime cause of deprivation and poverty led them to actively seek improved social legislation and programs (Addams, 1910: Leighninger and Midgley, 1997)

The Delta E-Commerce Connection: Preliminary Findings

A USDA Fund for Rural America project is creating economic opportunities for small agricultural and rural businesses in the Lower Mississippi Delta by assisting in e-commerce business development. Select rural businesses are provided technical support in web site development, marketing strategy formulation, electronic retailing services, and space on a secure server for one year. Businesses retaining web sites after this time assume responsibility for maintaining and funding the site. Characteristics of rural businesses adopting e-commerce are compared with those not adopting. Preliminary results suggest the amount of time invested in initial web site design, satisfaction with design, economic benefits from owning a web site, and number of levels traveled in the e-commerce roadmap (a measure of technological progress) as determinants of success. These findings will assist in selecting and guiding participant involvement to maximize the likelihood of success

Art Meets Sport::What Can Actor Training Bring to Physical Literacy Programs?

The aim of this communication is to highlight synergies and opportunities between the fields of education, sport and health and the performing arts for the promotion of physical literacy. First, physical literacy is introduced and then defined according to the definition used in this communication. Secondly, we highlight the gap in physical literacy interventions, in that they do not address learning based on a holistic comprehensive definition of physical literacy. Then we provide examples of interventions that do borrow from the arts, such as circus arts, and show how these approaches explicitly link to the discipline of arts. This is followed by program examples, which approach motor and language development from discipline-specific perspectives. Then we introduce actor training (within the discipline of arts) in terms of how this approach may be useful to our understanding of physical literacy and how to expand the conception of physical literacy to include affective meaning making, and tolerance for ambiguity and discomfort in not-knowing. Finally, we conclude with the next step for the bridging of disciplines in order to further our journey to understand and improve physical literacy

The Protein Storage Vacuole: A Unique Compound Organelle

doi: 10.1083/jcb.200107012Storage proteins are deposited into protein storage vacuoles (PSVs) during plant seed development and maturation and stably accumulate to high levels; subsequently, during germination the storage proteins are rapidly degraded to provide nutrients for use by the embryo. Here, we show that a PSV has within it a membrane-bound compartment containing crystals of phytic acid and proteins that are characteristic of a lytic vacuole. This compound organization, a vacuole within a vacuole whereby storage functions are separated from lytic functions, has not been described previously for organelles within the secretory pathway of eukaryotic cells. The partitioning of storage and lytic functions within the same vacuole may reflect the need to keep the functions separate during seed development and maturation and yet provide a ready source of digestive enzymes to initiate degradative processes early in germination.This work was supported by grants from the National Science Foundation (MCB-9974429), Department of Energy (DE-FG03-97ER20277), and Human Frontier Science Program (RG0018/2000) to J.C.

Histiocytoid cardiomyopathy and microphthalmia with linear skin defects syndrome: phenotypes linked by truncating variants in NDUFB11

Variants in NDUFB11, which encodes a structural component of complex I of the mitochondrial respiratory chain (MRC), were recently independently reported to cause histiocytoid cardiomyopathy (histiocytoid CM) and microphthalmia with linear skin defects syndrome (MLS syndrome). Here we report an additional case of histiocytoid CM, which carries a de novo nonsense variant in NDUFB11 (ENST00000276062.8: c.262C > T; p.[Arg88*]) identified using whole-exome sequencing (WES) of a family trio. An identical variant has been previously reported in association with MLS syndrome. The case we describe here lacked the diagnostic features of MLS syndrome, but a detailed clinical comparison of the two cases revealed significant phenotypic overlap. Heterozygous variants in HCCS (which encodes an important mitochondrially targeted protein) and COX7B, which, like NDUFB11, encodes a protein of the MRC, have also previously been identified in MLS syndrome including a case with features of both MLS syndrome and histiocytoid CM. However, a systematic review of WES data from previously published histiocytoid CM cases, alongside four additional cases presented here for the first time, did not identify any variants in these genes. We conclude that NDUFB11 variants play a role in the pathogenesis of both histiocytoid CM and MLS and that these disorders are allelic (genetically related)

Prehospital Systolic Blood Pressure Thresholds: A Community‐based Outcomes Study

Objectives Emergency medical services (EMS) personnel commonly use systolic blood pressure ( sBP ) to triage and treat acutely ill patients. The definition of prehospital hypotension and its associated outcomes are poorly defined. The authors sought to determine the discrimination of prehospital sBP thresholds for 30‐day mortality and to compare patient classification by best‐performing thresholds to traditional cutoffs. Methods In a community‐based cohort of adult, nontrauma, noncardiac arrest patients transported by EMS between 2002 and 2006, entries to state hospital discharge data and death certificates were linked. Prehospital sBP thresholds between 40 and 140 mm Hg in derivation ( n =  132,624) and validation ( n =  22,020) cohorts and their discrimination for 30‐day mortality, were examined. Cutoffs were evaluated using the 0/1 distance, Youden index, and adjusted Z‐statistics from multivariable logistic regression models. Results In the derivation cohort, 1,594 (1.2%) died within 24 hours, 7,404 (6%) were critically ill during hospitalization, and 6,888 (5%) died within 30 days. The area under the receiver operating characteristic (ROC) curve for sBP was 0.60 (95% confidence interval [CI] = 0.59, 0.61) for 30‐day mortality and 0.64 (95% CI = 0.62 0.66) for 24‐hour mortality. The 0/1 distance, Youden index, and adjusted Z‐statistics found best‐performing sBP thresholds between 110 and 120 mm Hg. When compared to an sBP ≤ 90 mm Hg, a cutoff of 110 mm Hg would identify 17% ( n =  137) more deaths at 30 days, while overtriaging four times as many survivors. Conclusions Prehospital sBP is a modest discriminator of clinical outcomes, yet no threshold avoids substantial misclassification of 30‐day mortality among noninjured patients. Resumen Los Umbrales de la Presión Arterial Sistólica Prehospitalaria: Un Estudio de Base Comunitaria Acerca de la Evolución de los Pacientes Objetivos El personal de los sistemas de emergencias médicas ( SEM ) usa frecuentemente la presión arterial sistólica ( PAS ) para clasificar y tratar a los pacientes agudos. Las definiciones de hipotensión prehospitalaria y sus resultados asociados están pobremente definidos. Se determinó la discriminación de los umbrales de PAS prehospitalaria para la mortalidad a los 30 días, y se comparó la clasificación del paciente por los mejores umbrales con los puntos de corte tradicionales. Metodología Estudio de cohorte de base comunitaria de pacientes adultos no traumatológicos ni con paradas cardiorrespiratorias transportados por los SEM entre 2002 y 2006, cuyas historias estaban vinculadas con los datos de alta hospitalaria y los certificados de mortalidad. Se examinaron los umbrales de PAS prehospitalaria entre 40 mm Hg y 140 mm Hg en las cohortes de derivación ( n =  132.624), y validación ( n =  22,020), y su discriminación para la mortalidad a los 30 días. Los puntos de corte se evaluaron usando la distancia 0/1, el índice de Youden y los estadísticos Z ajustados de los modelos de regresión logística multivariable. Resultados: En la cohorte de derivación, 1.594 (1,2%) fallecieron en las primeras 24 horas, 7.404 (6%) estuvieron críticamente enfermos durante el ingreso y 6.888 (5%) fallecieron en los 30 primeros días. El área bajo la curva de la ROC para PAS fue 0,60 ( IC 95% = 0,59–0,61) para la mortalidad a los 30 días y 0,64 ( IC 95% = 0,62–0,66) para la mortalidad a las 24 horas. La distancia 0/1, el índice de Youden y las estadísticas Z ajustadas hallaronque los mejores umbrales de PAS estaban entre 110 y 120 mm Hg. Cuando se comparó con una PAS ≤ 90 mm Hg, un punto de corte de 110 mm Hg identificaría un 17% ( n =  137) más de muertes a los 30 días, mientras que sobreclasificaría cuatro veces más a los supervivientes. Conclusiones La presión arterial sistólica es un discriminador modesto de resultados clínicos. No obstante, ningún umbral evita una mala clasificación de la mortalidad a los 30 días entre los pacientes no traumatológicos.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/1/acem12142-sup-0002-DataSupplementS2_FigS1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/2/acem12142-sup-0007-DataSupplementS7_FigS4.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/3/acem12142-sup-0006-DataSupplementS6_FigS3.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/4/acem12142-sup-0009-DataSupplementS9_TableS3.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/5/acem12142-sup-0003-DataSupplementS3.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/6/acem12142-sup-0008-DataSupplementS8_TableS2.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/7/acem12142-sup-0004-DataSupplementS4_TableS1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/8/acem12142-sup-0001-DataSupplementS1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/98303/9/acem12142.pd

Use of ultrasonics in swine improvement

"Today's swine producer must produce pork that is highly acceptable to consumers yet within a cost that permits a profit. Ultrasonics allows objective measurement of back fat and loin-eye area, two traits that recent research has shown to have a close relationship to total red meat in an animal. Progressive swine breeders consider these two highly inherit- able carcass traits in their selection programs to increase the red meat portion of animals. Ultrasonics will aid future development and improvement of swine herds by helping producers identify exceptional animals to go into the breeding herd. Knowing the perfor- mance and traits of individual animals is important since back fat and loin-eye area vary considerably among litter mates. In fact, measurements from the sire himself are as good a basis for evaluation of the sire as are carcass measurements from 20 of his offspring. Accuracy of results with ultrasonics depends on the technician's knowledge of the animal's anatomy ."--First page.M.A. Alexander, J. W. Massey, R. K. Leavitt, and John C.

Recruitment, retention, and training of people with type 2 diabetes as diabetes prevention mentors (DPM) to support a healthcare professional-delivered diabetes prevention program:The Norfolk Diabetes Prevention Study (NDPS)

Objective: Intensive lifestyle interventions reduce the risk of type 2 diabetes in populations at highest risk, but staffing levels are usually unable to meet the challenge of delivering effective prevention strategies to a very large at-risk population. Training volunteers with existing type 2 diabetes to support healthcare professionals deliver lifestyle interventions is an attractive option. Methods: We identified 141 973 people at highest risk of diabetes in the East of England, screened 12 778, and randomized 1764 into a suite of type 2 diabetes prevention and screen detected type 2 diabetes management trials. A key element of the program tested the value of volunteers with type 2 diabetes, trained to act as diabetes prevention mentors (DPM) when added to an intervention arm delivered by healthcare professionals trained to support participant lifestyle change. Results: We invited 9951 people with type 2 diabetes to become DPM and 427 responded (4.3%). Of these, 356 (83.3%) were interviewed by phone, and of these 131 (36.8%) were interviewed in person. We then appointed 104 of these 131 interviewed applicants (79%) to the role (mean age 62 years, 55% (n=57) male). All DPMs volunteered for a total of 2895 months, and made 6879 telephone calls to 461 randomized participants. Seventy-six (73%) DPMs volunteered for at least 6 months and 66 (73%) for at least 1 year. Discussion: Individuals with type 2 diabetes can be recruited, trained and retained as DPM in large numbers to support a group-based diabetes prevention program delivered by healthcare professionals. This volunteer model is low cost, and accesses the large type 2 diabetes population that shares a lifestyle experience with the target population. This is an attractive model for supporting diabetes prevention efforts
