Authors: Goldman Roberta E , Brown Joanna , Stebbins Patricia , Parker Donna R , Adewale Victoria , Shield Renee , Roberts Mary B , Eaton Charles B , Borkan Jeffrey M
Published: June 2018

Objectives:

Patient-centered medical home transformation initiatives for enhancing team-based, patient-centered primary care are widespread in the United States. However, there remain large gaps in our understanding of these efforts. This article reports findings from a contextual, whole system evaluation study of a transformation intervention at eight primary care teaching practice sites in Rhode Island. It provides a picture of system changes from the perspective of providers, staff, and patients in these practices.

Methods:

Quantitative/qualitative evaluation methods include patient, provider, and staff surveys and qualitative interviews; practice observations; and focus groups with the intervention facilitation team.

Results:

Patient satisfaction in the practices was high. Patients could describe observable elements of patient-centered medical home functioning, but they lacked explicit awareness of the patient-centered medical home model, and their activation decreased over time. Providers’ and staff’s emotional exhaustion and depersonalization increased slightly over the course of the intervention from baseline to follow-up, and personal accomplishment decreased slightly. Providers and staff expressed appreciation for the patient-centered medical home as an ideal model, variously implemented some important patient-centered medical home components, increased their understanding of patient-centered medical home as more than specific isolated parts, and recognized their evolving work roles in the medical home. However, frustration with implementation barriers and the added work burden they associated with patient-centered medical home persisted.

Conclusion:

Patient-centered medical home transformation is disruptive to practices, requiring enduring commitment of leadership and personnel at every level, yet the model continues to hold out promise for improved delivery of patient-centered primary care.
Spiritual health mediates the relationship between ego-strength and adjustment to heart disease
Authors: Besharat Mohammad Ali , Ramesh Somayeh , Moghimi Elham
Published: June 2018

This study aimed to investigate the mediating role of spiritual health in the relationship between ego-strength and adjustment to heart disease. In total, 327 patients with coronary artery disease (138 women, 189 men) completed the Ego-Strength Scale, Adjustment to Illness Scale, and Spiritual Well-Being Scale. Results showed that both ego-strength and spiritual health had a significantly positive correlation with adjustment to heart disease. Results also revealed that spiritual health mediated the relationship between ego-strength and adjustment to heart disease. More improvement in adjustment to heart disease requires more improvement in patients’ spiritual health as well as to ego-strength.
Language, Ethnicity, and Belonging for the Children of Migrants in New Zealand
Authors: Cunningham Una , King Jeanette
Published: June 2018

The children of migrants grow up with influence from at least two cultures, and they must negotiate their path to adulthood through one or more ethnicities and one or more language varieties that may set them apart from the majority population. We asked how teenagers born to migrant parents in an English-speaking context appeal to the cultures and/or ethnicities they identify with to explain their language choices and perceptions of belonging. More than 50 interviews were carried out with teenagers who identified as speakers of the minority language of their parents (Chinese, Dutch, French, German, Korean, or Spanish), and one or both parents of such young people. The focus of the interviews was the minority language, but they became narratives of belonging. Thematic analysis of the transcribed and (where necessary) translated interviews revealed patterns in the perceptions of the teens and their parents. The reported self-perceived proficiency of the teenagers in the minority language, their perception of their ethnicity (particularly but not exclusively for the Chinese and Korean teens) and the culture of the host country, diasporic, and home country communities- were factors in when and how the teens chose to use the minority language, and in how they identified as, for example, Dutch. More than 160 languages are spoken in New Zealand; 25% of the population was born elsewhere, yet the country is one of the most monolingual in the world. This study reveals tensions affecting the willingness of New Zealand–born young people to openly identify with their parents’ ethnicity and to use their languages. Lessons learned from those who raised bilingual children in New Zealand in the face of minimal official support and overwhelming pressure from English will be valuable to other parents and caregivers in New Zealand and elsewhere.
Exploring the Factors That Affect Employee Training Effectiveness: A Case Study in Bahrain
Authors: EL Hajjar Said Taan , Alkhanaizi Madina Sughra
Published: June 2018

Training is a systematic way to improve the performance of employees, and it provides a link between job requirements and the current job specification of the employees. In addition, training requires time, energy, and money. At this juncture, organization must look for the needs to evaluate training programs and assess its impact on both performance and behavior of trainees. This study aimed to explore the factors affecting the training effectiveness of training programs, in the Kingdom of Bahrain. A survey questionnaire was used as a tool to gather data to answer the research questions in this study, the weighted mean was used to measure the central tendency on each dimension in the questionnaire. Likewise, a correlation test was used to find out the relationship between the contents, training environment, facilities and materials, training schedule, presentation style from one side with the training effectiveness from other side. Moreover, regression test examined the effect of the factors on training effectiveness. Survey questionnaires were distributed to trainees to collect the primary data for the research; the response rate was more than 65%. The results of the survey suggested that the respondents had neutral perceptions on all factors. Likewise, it could be concluded that there was a strong positive linear correlation between the five factors and training effectiveness. This result supported training managers in designing the training programs. In addition, instructional designers and trainers might be able to identify the features of training programs by maximizing the output redounded to the learning abilities and skills of the trainees.

Authors: Bae Sung-Heui , Hwang Sung-Woo , Lee Gunjeong
Published: June 2018

This cross-sectional study used quantitative survey data collected from registered nurses (RNs) who worked as staff nurses in medium-sized (300 beds or less) Korean hospitals. Data from 290 RNs were analyzed to examine the nature and prevalence of staff nurses’ work hours, overtime, breaks, and related work conditions. The results showed that staff nurses working in medium-sized Korean hospitals worked 9.6 hours a day on average and had 1.5 breaks daily, including mealtime. The average number of days the nurses skipped a meal due to work during the last month was 6.1. With respect to skipping bathroom breaks due to work, staff nurses reported that they could not visit the bathroom 7.3 times during the last month. Regarding work conditions, staff nurses working in intensive care units reported having longer daily work hours and were more likely to work 10 hours or more per shift. Nurses with less than 3 years of experience reported longer daily work hours and fewer breaks.
Caste–Gender Intersectionality and Atrocities in Haryana: Emerging Patterns and State Responses
Authors: Pal G. C.
Published: June 2018

In the Indian society, the issue of gender and caste inequality has drawn considerable attention in the discourse of social exclusion. The complex relationship between these two culturally powerful identities in the context of violence and atrocities remains stubbornly in place. This article analyses the patterns and consequences of intersectional atrocities and the responses of state machinery in a specific sociocultural context, that is, in the state of Haryana. Despite showing faster economic development than other states, Haryana has been in the limelight for its traditions and customs conflicting with the freedom of lower castes (dalits) and women. The article draws evidence from the official data on crimes and information based on mainstream media reportage and documents of civil society organisations, to argue that a society, which culturally accepts caste and gender hierarchy and allows this culture to permeate in public institutions, accentuates the vulnerability of women from lower caste to structural, systematic and symbolic atrocities.
Translating anti-CD19 CAR T-cell therapy into clinical practice for relapsed/refractory diffuse large B-cell lymphoma
Authors: Chow Victor A. , Shadman Mazyar , Gopal Ajay K.
Published: June 2018

Chimeric antigen receptor T cells demonstrate efficacy in B-cell malignancies, leading to US Food and Drug Administration approval of axicabtagene ciloleucel (October 2017) and tisagenlecleucel (May 2018) for large B-cell lymphomas after 2 prior lines of therapy. Durable remissions are seen in 30% to 40% of study-treated patients, but toxicities of cytokine release syndrome and neurotoxicity require administration in specialized centers. This article reviews data of current diffuse large B-cell lymphoma management, focusing on axicabtagene ciloleucel, tisagenlecleucel, and lisocabtagene maraleucel.

The natural history and epidemiology ofPseudomonas aeruginosainfections in non-cystic fibrosis (non-CF) bronchiectasis is not well understood.

As such it was our intention to determine the evolution of airway infection and the transmission potential ofP. aeruginosain patients with non-CF bronchiectasis.

A longitudinal cohort study was conducted from 1986–2011 using a biobank of prospectively collected isolates from patients with non-CF bronchiectasis. Patients included were ≥18 years old and had ≥2 positiveP. aeruginosacultures over a minimum 6-month period. All isolates obtained at first and most recent clinical encounters, as well as during exacerbations, that were morphologically distinct on MacConkey agar were genotyped by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). A total of 203 isolates from 39 patients were analysed. These were compared to a large collection of globally epidemic and local CF strains, as well as non-CF isolates.

We identified four patterns of infection in non-CF bronchiectasis including: 1) persistence of a single strain (n=26; 67%); 2) strain displacement (n=8; 20%); 3) temporary disruption (n=3; 8%); and 4) chaotic airway infection (n=2; 5%). Patterns of infection were not significant predictors of rates of lung function decline or progression to end-stage disease and acquisition of new strains did not associate with the occurrence of exacerbations. Rarely, non-CF bronchiectasis strains with similar pulsotypes were observed in CF and non-CF controls, but no CF epidemic strains were observed. While rare shared strains were observed in non-CF bronchiectasis, whole-genome sequencing refuted patient–patient transmission.

We observed a higher incidence of strain-displacement in our patient cohort compared to those observed in CF studies, although this did not impact on outcomes.
How to incorporate patient and public perspectives into the design and conduct of research
Authors: Hoddinott Pat , Pollock Alex , O'Cathain Alicia , Boyer Isabel , Taylor Jane , MacDonald Chris , Oliver Sandy , Donovan Jenny L.
Published: June 2018

International government guidance recommends patient and public involvement (PPI) to improve the relevance and quality of research.  PPI is defined as research being carried out ‘with’ or ‘by’ patients and members of the public rather than ‘to’, ‘about’ or ‘for’ them (http://www.invo.org.uk/). Patient involvement is different from collecting data from patients as participants.  Ethical considerations also differ.  PPI is about patients actively contributing through discussion to decisions about research design, acceptability, relevance, conduct and governance from study conception to dissemination.  Occasionally patients lead or do research.  The research methods of PPI range from informal discussions to partnership research approaches such as action research, co-production and co-learning.

This article discusses how researchers can involve patients when they are applying for research funding and considers some opportunities and pitfalls.  It reviews research funder requirements, draws on the literature and our collective experiences as clinicians, patients, academics and members of UK funding panels.

Las percepciones de la inseguridad en relación con las noticias delictivas: un análisis desde la recepción
Authors: Focás Brenda
Published: June 2018

Los medios de comunicación —específicamente la televisión— son señalados como uno de los responsables de la creciente inquietud por la inseguridad. Se sostiene que exageran en la enunciación de las noticias policiales, que tienen intereses o intenciones en generar miedo, que son sensacionalistas. Pero ¿cómo interpretan los sujetos a los medios cuando representan ‘la inseguridad’ y cómo decodifican esta información? ¿Qué lugar ocupan las noticias de inseguridad en la percepción de los sujetos? En este artículo se presentan algunos hallazgos que muestran, a través de un trabajo de recepción, los modos en que la información mediática de la inseguridad se imbrica en la vida cotidiana de los sujetos y con las distintas formas de percepción de los espectadores, de clasificación de la información, de interés cognitivo y de credibilidad en los medios cuando representan al delito.

Creating Work Breaks from Available Idleness
Authors: Sun Xu , Whitt Ward
Published: June 2018

We develop new rules for assigning available service representatives to customers in customer contact centers and other large-scale service systems in order to create effective work breaks for the service representatives from naturally available idleness. These are unplanned breaks occurring randomly over time. We consider both announced breaks as well as unannounced breaks. Our goal is to make the mean and variance of the interval between successive breaks suitably small. Given a target break duration, we propose assigning idle servers based on the elapsed time since their last break. We show that our proposed server-assignment rules are optimal for the many-server heavy-traffic (MSHT) fluid model. Extensive simulation experiments support the proposed server-assignment rules in practical cases and confirm the MSHT approximation formulas when the number of servers is very large.

Cultural Imprinting, Institutions, and the Organization of New Firms
Authors: Waguespack David M. , Dunford Eric T. , Birnir Jóhanna K.
Published: June 2018

Do firm founders from nations with more predictable and transparent institutions allocate more autonomy to their employees? A cultural imprinting view suggests that institutions inculcate beliefs that operate beyond the environment in which those beliefs originate. We leverage data from a multiplayer online role-playing game, EVE Online, a setting where individuals can establish and run their own corporations. EVE players come from around the world, but all face the same institutional environment within the game. This setting allows us to disentangle, for the first time, cultural norms from the myriad other local factors that will influence organizational design choices across nations. Our main finding is that founders residing in nations with more predictable and transparent real world institutions delegate more authority within the virtual firms they create.

Published: June 2018

Este artículo tiene como objetivo examinar la distribución geográfica del delito de robo a casa habitación en Ciudad Juárez. Éste es uno de los delitos con menor atención pública con un promedio anual de 910 averiguaciones durante el periodo 2010-2015. El robo a casa habitación no presenta una distribución geográfica homogénea en la ciudad, muestra una alta concentración en la Zona Centro y algunas colonias como son: Primero de Mayo, Granjas Chapultepec, Revolución Mexicana, entre otras. En este contexto el objetivo del trabajo de investigación es: examinar la relación geográfica entre la localización de los robos a casa habitación y características del entorno urbano de Ciudad Juárez. El soporte teórico del artículo lo proporcionan el enfoque de la criminología ambiental. La información usada del robo a casa habitación corresponde a las averiguaciones previas recopiladas de la Secretaría de Seguridad Pública del Municipio de Juárez y variables del Censo General de Población y Vivienda 2010. La metodología es el análisis espacial, para medir la distribución se utilizó el análisis exploratorio de datos espaciales; para valorar la relación espacial se aplicó un modelo de regresión geográficamente ponderado tipo Poisson. Los resultados identifican cuatro variables tales como viviendas deshabitadas, la densidad de población, los hogares con jefatura femenina y concentración de población joven como factores que influyen en el robo a casa habitación. Lo resultados apuntan al diseño de estrategias preventivas centradas en los lugares.

Factores que inciden en la implementación de TIC en la enseñanza de Biología en una escuela secundaria.
Authors: Larraburu Sandra , Fabro Ana Patricia
Published: June 2018

La investigación se realizó en el ámbito de la Escuela Secundaria Técnico-profesional Nº 483 de Venado Tuerto, provincia de Santa Fe.

El objetivo de la misma fue analizar los factores actitudinales y contextuales que inciden en la incorporación de TIC a la enseñanza de Biología, en primer año de la mencionada escuela.

Como resultados se observa que si bien el equipamiento tecnológico de la escuela estudiada es satisfactorio, los docentes de Biología de primer año, en su mayoría, no utilizan estos recursos en forma periódica, y cuando lo hacen, los emplean como un complemento más del formato de sus clases tradicionales.

Sin embargo, se destaca el trabajo de una docente que aprovecha los saberes tecnológicos de los alumnos, para el aprendizaje de los saberes curriculares de la disciplina Biología dentro de un modelo de enseñanza constructivista, desarrollando sus clases de manera creativa, lúdica e imaginativa, ofreciendo a los alumnos un abanico de posibles tareas o actividades, para que éstos desarrollen experiencias activas mediadas por TIC.

En cuanto a los diferentes factores actitudinales que inciden en la incorporación de TIC a la enseñanza de Biología, se puede observar que los docentes manifiestan principalmente actitudes de indiferencia, rechazo, miedo, desinterés, apatía y frustración frente a las TIC.

Con respecto a los factores contextuales que inciden en la incorporación de las TIC en el ámbito de la enseñanza, para el caso estudiado, se puede concluir que son diversos, según las diferentes dimensiones o niveles de responsabilidad.

En cuanto al nivel macrocontextual, se observa que los docentes pueden acceder gratuitamente a numerosos programas que se brindan a nivel nacional y provincial.

Sin embargo, pese a la gran oferta de cursos y actividades de capacitación de los programas mencionados, los docentes no conocen (en su mayoría) los objetivos de estos programas, y han abandonado los cursos que los mismos brindan, porque -según su opinión- les ofrecen demasiado material teórico (que según manifiestan, no tienen tiempo de leer) y poco material práctico. Solamente una docente (de los cuatro docentes analizados) terminó el postítulo de Especialización en TIC, brindado por el Ministerio de Educación de la Nación.

En cuanto al nivel microcontextual, los docentes manifiestan no tener tiempo para capacitarse ni para la preparación de secuencias didácticas mediadas por TIC. Asimismo, si bien algunos de los docentes entrevistados manifiestan no encontrar obstáculos para la utilización de las TIC en las aulas (al tiempo que sostienen que no las aplican porque no les interesa) otros docentes señalan como obstáculos, la ausencia de conectividad en determinadas circunstancias y la falta de hábito de los alumnos de llevar las netbooks provistas por el programa Conectar Igualdad, a la escuela.

Published: June 2018

O objetivo do presente trabalho foi avaliar o crescimento e desenvolvimento inicial de plantas jovens de Aspidosperma pyrifolium Mart. quando submetidas a déficit hídrico em casa de vegetação. O delineamento experimental foi inteiramente casualizado, com três tratamentos hídricos [rega diária como controle (C) e intervalos de sete (E-7) e quatorze dias (E-14) entre regas], com onze repetições por tratamento, durante 98 dias. Foram avaliados altura, diâmetro do caule, número de folhas, teor relativo de água (TRA), tolerância protoplasmática, clorofila, área foliar e produção de matéria seca. Houve diferença significativa entre os tratamentos. As plantas estressadas se desenvolveram melhor que o tratamento controle em praticamente todas as variáveis observadas. Não houve diferença significativa para o TRA e índice de clorofila. Os resultados demonstram que A. pyrifolium não sofre alterações morfofisiológicas significativas quando submetidas a seca intermitente. Na verdade, o estresse parece atuar como um promotor de crescimento e desenvolvimento para a espécie na fase inicial.
Situación del pequeño escarabajo, Aethina tumida, en colmenas de abejas africanizadas (Apis mellifera) en Costa Rica: Muestreo de apiarios 2014-2017
Authors: Ramírez Marianyela , Calderón Rafael A.
Published: June 2018

El primer reporte sobre la presencia del pequeño escarabajo de la colmena, Aethina tumida en Centroamérica se dio en El Salvador en el 2013, luego se confirmó en Nicaragua en el 2014, lo cual aumenta el riesgo de su ingreso a Costa Rica. Por lo anterior, en el presente estudio se realizó un muestreo que va de junio 2014 a setiembre 2017, mediante el cual se analizaron 359 colmenas pertenecientes a 62 apiarios ubicados en las provincias de Guanacaste, Puntarenas, Alajuela, San José y Heredia. Se realizaron observaciones de la cría y de las abejas adultas, además se colocaron dos trampas por colmena tipo Cutts Beetle Blaster®, las que permanecieron durante ocho a quince días. Posteriormente las trampas se analizaron en el laboratorio de Patología Apícola del CINAT-UNA. Del total de apiarios muestreados, se confirmó la presencia del pequeño escarabajo únicamente en un apiario centinela ubicado en La Cruz-Guanacaste, en agosto 2015. Por lo anterior, se puede indicar la presencia del pequeño escarabajo A. tumida en colmenas de abejas africanizadas en Costa Rica, con una distribución limitada a la Cruz-Guanacaste. Tomando en cuenta que el escarabajo adulto puede volar y desplazarse junto a enjambres silvestres y la trashumancia de colmenas por parte del apicultor, es importante mantener un monitoreo constante de los apiarios, ya que las condiciones actuales de ausencia en la mayoría de zonas apícolas del país, reportadas en el presente estudio, pueden cambiar.
Influence of railway loading on the performance of soil-filled masonry arch bridges
Authors: Augusthus-Nelson Levingshan , Swift Gareth M. , Smith Colin C. , Gilbert Matthew , Melbourne Clive
Published: June 2018

There is a large number of masonry arch bridges on the rail networks in Europe and other parts of the world. However, the mode of response of masonry arch structures subjected to railway loading is little understood. To address this, an experimental study involving large-scale physical models of backfilled masonry arch bridges subjected to railway loading conditions was conducted. The study explored the influence of the rail track–bed system on bridge behaviour and load-carrying capacity. The tests results indicated that the track–bed system fundamentally alters the mode of response of the bridge system and significantly increases load-carrying capacity. Using the same test facility, load tests were also used to explore and characterise the behaviour and performance of damaged arch bridges. The results obtained suggest that, although there is likely to be a reduction in overall capacity, even a significantly damaged arch bridge can still perform adequately under loading. This has important implications for bridge owners and assessment engineers.

Deficiency of long-chain polyunsaturated fatty acids in phenylketonuria: a cross-sectional study   Abstract            The etiology of altered blood fatty acid (FA) profile in phenylketonuria (PKU) is understood only partially.            We aimed to determine whether FAs deficiency is dependent on diet or metabolic disturbances.            The study comprised 40 PKU patients (20 female, 20 male; aged 11 to 35 years;  12 children and 28 adults) and 40 healthy subjects (HS; 20 female, 20 male, aged 18 to 33 years). We assessed the profile of FAs (gas chromatography/mass spectrometry) and analyzed the 72-hour dietary recalls.            The amount of C14:0, C16:0 and C16:1n-7, C18:1n-9 did not differ between the analyzed groups. The percentage of C18:0 was higher, while C20:3n-9, C18:2n-6, C20:2n-6, C20:4n-6, C22:4n-6, C22:5n-6 and C22:6n-3 was lower in PKU than in HS. However, C18:3n-6, C18:3n-3 and n-6/n-3 ratio were higher in PKU patients. The C20:4n-6/C20:3n-6 ratio (reaction catalyzed by Δ5-desaturase), the C22:5n-6/C22:4n-6 and the C22:6n-3/C22:5n-3 ratio (both reactions catalyzed by Δ6-desaturase) were significantly lower in PKU patients.            The deficiency of long-chain polyunsaturated fatty acids in PKU patients may result not only from inadequate supply but also from metabolic disturbances.
Assessment of genetic variability and inter-character association in the germplasm of cowpea (Vigna Unguiculata L. Walp) in hot arid climate
Authors: Singh Om Vir , Shekhawat Neelam , Singh Kartar , Gowthami R.
Published: June 2018

Studies on genetic variability, correlation and path coefficient analysis were carried out with 38 accessions of cowpea (Vigna unguiculata L. Walp.) evaluated in two environments i. e. kharif 2013 (E1) and kharif 2014 (E2) at Research field of NBPGR, Regional Station Jodhpur, India. Analysis of variance revealed significant differences among the genotypes for all the traits. Genotypic coefficient of variation was highest for number of clusters per plant followed by number of pods per plant in both the environments. High broad sense heritability along with high genetic advance for seed yield per plant, 100 seed weight, pod length, number of pods per plant, peduncle length, number of clusters per plant, number of branches per plant and plant height indicated the presence of additive gene effects for these traits in cowpea. In both the environments seed yield per plant was positively correlated with 100 seed weight, pod length, number of pods per plant, number of clusters per plant, number of branches per plant and plant height. The highest positive direct effect registered by number of branches per plant followed by number of clusters per plant in E1 environment and by number of branches per plant followed by plant height in E2 environment. The traits like 100 seed weight, plant height, number of pods per plant number of clusters per plant and number of branches per plant were identified as selection criteria for obtaining good parental lines in cowpea breeding programmes.

Published: June 2018

The present study was planned to evaluate the performance of groundnut (Arachis hypogaea L.) under varying levels of sulphur and its sources under Semi-Arid condition of Rajasthan. Application of 60 kg S/ha resulted 8.8, 23.8 and 59.6% more pod/plant than 45, 30 and 15 kg S/ha, respectively. Gypsum as a source of S recorded 15.4 and 50.4% higher pods/plant over SSP and elemental sulphur, respectively. However, number of kernels/pod increased significantly upto 45 kg/ha only. Gypsum and SSP improved the kernels/pod by 14.2 and 11.2% over elemental sulphur, respectively. Application of 60 kg S/ha resulted in 140, 345 and 744 kg/ha and 127, 319 and 616 kg/ha higher pod and kernel yield over 45, 30 and 15 kg/ ha, respectively. Sulphur application through gypsum recorded the highest pod yield (1872 kg/ha) of groundnut that was 13.1 and 32.0 percent more than obtained under SSP and elemental sulphur treatment, respectively. Application of sulphur at 75 kg S/ha was recorded highest shelling% (72.13%) which were 7.0 and 10.9 per cent higher over 30 and 15 kg S/ha. The application of S at 45 kg/ha exhibited 7.6 and 17.0% higher protein content over 30 and 15 kg S/ha, respectively. Among sources, the highest protein content (23.75%), oil content (44.49%) and oil yield (597.76 kg/ha) was obtained with gypsum. Application of 60 kg S/ha increased oil yield by magnitude of 70.3, 175.1 and 316.9 kg/ha over 45, 30 and 15 kg S/ha, respectively. Sulphur application at the rate of 60 kg/ha increased the margin to the tune of 6343, 15867, 34062 /ha over 45, 30 and 15 kg S/ha, respectively. Likewise, graded increment in levels of sulphur resulted in significantly higher BCR upto 60 kg/ha over lower levels. The maximum net returns (55358/ha) and BCR (1.68) were obtained with gypsum.

Investigations on biological activities of pod borer, Helicoverpa armigera (Hubner) on 20 promising chickpea genotypes using detached leaf assay method at Agriculture Research Station Kalaburagi, UAS, Raichur, Karnataka was carried out during rabi 2016-17. The results revealed that at vegetative and flowering stage there was significantly lesser larval survival (70 to 76.67 %), larval weight (8.37 to 8.90 mg) and damage rate (3.67 to 4.67 of visual Rating in 1-9 Scale) on resistant check ICCL 86111, HC-1 and DBGV-3104 genotypes where as maximum per cent larval survival (86.67 to 90 %), larval weight (13.60 to 14.10 mg) and damage rate (7.67 to 8.00 of visual Rating in 1-9 Scale) was recorded in susceptible checks (ICC-3137, A-1 and JG-11). During pod formation stage, highest weight gain by larvae was noticed on susceptible check ICC-3137 (409.18 mg), on the contrary lowest weight gain by larvae was found on resistant check ICCL-86111 (275.43 mg) also these genotypes recorded more amount of malic acid and trichomes indicating that biological activity of insect was affected through antibiosis mechanism which is one of the component of resistance to H. armigera in chickpea.
Is the default of 2 liters for daily per-capita water consumption appropriate? A nationwide survey reveals water intake in Japan

Published: June 2018

Two liters per day is generally applied as the default drinking water intake rate for risk assessments, although evidence supporting this value is insufficient. This study aimed to reveal actual water intakes from tap water and other types of drinks, and to explore the relationships between these intakes. For this purpose, we conducted a nationwide Internet questionnaire survey. Tap water intake negatively correlated with bottled water and soft drink intakes, suggesting a mutually complementary relationship. We propose an index, potential Tap Water Intake (pTWI), calculated by adding soft drinks and bottled water to tap water intake. Mean per-capita tap water intake across the entire Japanese population was estimated at 1.28 L/d, whereas mean pTWI was estimated at 1.65 L/d. Two liters per day corresponds to the 88th percentile of tap water intake and to the 76th percentile of pTWI, and covers the intake of the majority of the population in Japan. This rate should continue being used as the default in the Japanese population, but the rate to cover the tap water intake of almost the entire population would be higher: it was >2.5 L/d.

Background

Dementia is an international research priority. Reminiscence is an intervention that prompts memories and has been widely used as a therapeutic approach for people living with dementia. We developed a novel iPad app to support home-based personalized reminiscence. It is crucial that technology-enabled reminiscence interventions are appraised.

Objective

We sought to measure the effect of technology-enabled reminiscence on mutuality (defined as the level of “closeness” between an adult living with dementia and their carer), quality of carer and patient relationship, and subjective well-being.

Methods

A 19-week personalized reminiscence intervention facilitated by a program of training and a bespoke iPad app was delivered to people living with dementia and their family carers at their own homes. Participants (N=60) were recruited in dyads from a cognitive rehabilitation team affiliated with a large UK health care organization. Each dyad comprised a person living with early to moderate dementia and his or her family carer. Outcome measurement data were collected at baseline, midpoint, and intervention closure.

Results

Participants living with dementia attained statistically significant increases in mutuality, quality of carer and patient relationship, and subjective well-being (P<.001 for all 3) from baseline to endpoint. Carers attained nonsignificant increases in mutuality and quality of carer and patient relationship and a nonsignificant decrease in subjective well-being.

Conclusions

Our results indicate that individual-specific reminiscence supported by an iPad app may be efficient in the context of early to moderate dementia. A robust randomized controlled trial of technology-enabled personalized reminiscence is warranted.
Some sigmoid and reverse-sigmoid response patterns emerging from high-power loading of solids
Authors: Mastilovic Sreten
Published: June 2018

The objective of the present review is twofold. First, it aims at
highlighting some sigmoid and reverse-sigmoid response patterns observed
recently in the course of simulations of the high-strain-rate loading of
(mostly, quasibrittle) solids. Second, it aims at reviewing various
properties of two models used frequently as curve fitting tools for
nonlinear and saturable phenomena. These two models-inspired by the Hill and
the Weibull cumulative distribution functions-are bounded by two horizontal
asymptotes with a smooth transition between the baseline and the final
saturation state, characterized by a non-negative (a non-positive)
derivative at each point for the sigmoid (the reverse-sigmoid) shape.
Although they were used primarily for data fitting because of their
flexibility and effectiveness, these nonlinear models possess other
properties useful for the analysis of the irreversible, nonlinear and
far-from-equilibrium phenomena. The main features of these two models are
systematically examined in this review. In spite of the fact that
satisfactory curve-fitting of data could not be considered a proof of
causality it could underline a pattern of behavior and, perhaps, provide an
investigation guidance.

Objetivo: caracterizar os pacientes transplantados atendidos em uma unidade de alta complexidade e sua evolução clínica. Metodologia: estudo descritivo, documental, com abordagem quantitativa. Realizado em uma unidade pós-operatória de alta complexidade em transplantes, de um Hospital Público Terciário, do Município de Fortaleza. A amostra constituída por 109 fichas, dos pacientes transplantados renais, no período de janeiro de 2014 a julho de 2016. A coleta de dados foi realizada no período de fevereiro a março de 2017. Os resultados foram tabulados em uma planilha do programa Excel do Windows XP Profissional, com parecer favorável pelo comitê de ética do referido hospital, sob Protocolo nº 754.462. Resultados: houve uma predominância do sexo masculino em relação ao feminino. Predomínio da faixa etária de 29 a 39 anos, com 33% dos casos. Conforme identificado, o tipo de doação renal que mais se destacou foi de doador falecido, que representou 97,2% dos transplantes realizados, enquanto com doador vivo foi apenas 2,8%. Em relação ao tempo que os pacientes permaneceram em tratamento dialítico antes do transplante, observou-se uma predominância deste tratamento substitutivo por mais de 24 meses com 62,3% dos casos. Conclusão: o transplante renal não representa uma cura, e sim uma outra forma de tratamento substitutivo, é uma opção que abre possibilidades para uma vida bem próxima da normalidade.Descritores: Transplante de Rim.
