Patient Attitudes Toward Mobile Device Use by Health Care Providers in the Emergency Department: Cross-Sectional Survey (Preprint)
Authors: Alameddine Mohamad , Tamim Hani , Hadid Dima , Cheaito Mohamad-Ali , Makki Maha , Maatouk Hadi , Hitti Eveline
Published: November 2019

BACKGROUND

Health care provider usage of mobile devices is increasing globally; however, there is little understanding of patient perceptions on this behavior in a health care setting.

OBJECTIVE

The aim of this study was to assess patients’ attitudes toward mobile device usage by health care providers in the emergency department and to identify predictors of these attitudes.

METHODS

The study was carried out at the emergency department of a large academic tertiary care medical center in Lebanon. A cross-sectional survey design was adopted by administering a questionnaire to medically stable adult patients who presented to the emergency department with an emergency severity index of 3, 4, or 5 between January 2017 and March 2018. The questionnaire collected relevant patient demographic information and included questions related to their mobile device usage along with those evaluating attitudes for the use of mobile devices by health care providers with respect to six major domains: role in health care, distraction potential, impact on communication, empathy, privacy, and professionalism. The attitude toward mobile device usage by health care providers in the emergency department was the main outcome variable. A stepwise logistic regression model was used to assess the association between the outcome variable and the demographic and attitude-related independent variables.

RESULTS

Among the 438 eligible patients, 338 patients responded to the questionnaire for a response rate of 70.0%. Overall, 313/338 (92.6%) respondents agreed that mobile devices improve health care delivery, whereas 132/338 (39.1%) respondents were opposed to their usage by health care providers in the emergency department (95% CI: 34.0-44.4). The majority (240/338, 71.0%) of patients agreed that mobile devices are a source of distraction to health care providers in the workplace. Females (odds ratio [OR]=1.67, 95% CI: 1.00-2.78) as well as all patients (OR=2.54, 95% CI 1.36-4.76) who believed that mobile devices were a source of distraction, reflecting a lack of professionalism (OR=2.77, 95% CI 1.59-4.82) and impacting the provider’s ability to relate to the patient (OR=2.93, 95% CI 1.72-4.99), were more likely to agree that mobile devices should not be used in the emergency department.

CONCLUSIONS

Patients’ negative attitude toward mobile device use in the emergency department is largely driven by patient gender (females), patient perception of the distraction potential of the devices, and their negative impact on the health care provider’s empathy and professionalism. The findings of this study shed light on the importance of encouraging stakeholders to impose a digital professionalism code of conduct for providers working in acute health care settings.
Mobile Apps for Health Behavior Change: Protocol for a Systematic Review (Preprint)
Authors: Milne-Ives Madison , Lam Ching , Van Velthoven Michelle Helena , Meinert Edward
Published: November 2019

BACKGROUND

The popularity and ubiquity of mobile apps have rapidly expanded in the past decade. With a growing focus on patient interaction with health management, mobile apps are increasingly used to monitor health and deliver behavioral interventions. The considerable variation in these mobile health apps, from their target patient group to their health behavior, and their behavioral change strategy, has resulted in a large but incohesive body of literature.

OBJECTIVE

The purpose of this protocol is to provide an overview of the current landscape, theories behind, and effectiveness of mobile apps for health behavior change.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols will be used to structure this protocol. The focus of the systematic review is guided by a population, intervention, comparator, and outcome framework. A systematic search of Medline, EMBASE, CINAHL, and Web of Science will be conducted. Two authors will independently screen the titles and abstracts of identified references and select studies according to the eligibility criteria. Any discrepancies will then be discussed and resolved. One reviewer will extract data into a standardized form, which will be validated by a second reviewer. Risk of bias was assessed using the Cochrane Collaboration Risk of Bias tool, and a descriptive analysis will summarize the effectiveness of all the apps.

RESULTS

As of November 2019, the systematic review has been completed and is in peer review for publication.

CONCLUSIONS

This systematic review will summarize the current mobile app technologies and their effectiveness, usability, and coherence with behavior change theory. It will identify areas of improvement (where there is no evidence of efficacy) and help inform the development of more useful and engaging mobile health apps.

Published: November 2019

The purpose of this study is to describe the views of teachers on aspects of attitude assessment and aspects of skills assessment which after the implementation of Permen No 53 Year 2015 is very well looked at by teachers from the old regulations. The research method is qualitative descriptive research. This research was conducted at SDN 55/1 Sridadi, class I of the 2016 school year, namely in 2 first-class guardian teachers. Data obtained from the results of questionnaires, and semi-structured interviews. The results of the study describe the views of teachers on aspects of attitude assessment and aspects of skills assessment which after the implementation of Regulation No. 53 of 2015 was very well looked at by the teacher from the old regulations. The results of interviews in a structured way are obtained by the opinion of the teacher agreeing / good towards the new revision and the overall results of the distribution of the teacher questionnaire are already in a very good stage of understanding. So the teacher's perception of the new assessment system is good because the teacher can easily understand the implementation and implementation of the 2013 Curriculum with the issuance of Permen No 53 year 205, but the teacher still has problems in processing student grades which are considered complicated. Therefore, further training needs to be done so that the teacher's understanding of the assessment in the 2013 curriculum gets better.

Pengaruh Pemberian Kurma Muda (Phoenix dactylifera) Terhadap Kadar FSH dan Reseptor FSH Ovarium Tikus Putih (Rattus norvegicus)
Authors: Herlambang Herlambang , Rahman Ave Olivia , Kusdiyah Erny
Published: November 2019

ABSTRACT

Background: Infertility may give an impact on psychosocial. In Indonesia, the habit of consuming young dates is often done by couples to increase fertility. FSH is one of the factors that play a role in folliculogenesis. The lack of scientific evidence of young dates consumption effects on female reproduction has led to this study. This study aims to determine the levels of FSH hormone and the picture of ovarian tissue in mice after administration of young dates.

Method: This study used an experimental design using 28 female Sprague-Dawley rats which were randomly divided into 4 groups. Group I to III was given young dates in successive doses: 17 mg, 34 mg, 68 mg per 200 grams of body weight and group IV was given distilled water. The treatment was carried out for 28 days. FSH levels were examined before treatment during the proestrus phase which was known from microscopic examination of rat vaginal swabs. The treatment begins during the proestrus phase.

Result: The mean baseline and post-treatment FSH levels were 0.08 and 0.09 respectively

Conclusion: There is no significant increase of FSH levels and FSH receptors as the effect of giving young dates (Phoenix Dactylifera) to female Sprague-Dawley rats

Keywords: Dates, FSH, FSH receptors, Rats

 

ABSTRAK

Latar Belakang: Infertilitas dapat memberikan dampak psikososial. Di Indonesia, kebiasaan mengkonsumsi kurma muda sering dilakukan oleh pasangan untuk meningkatkan kesuburan. Hormon FSH merupakan salah satu faktor yang berperan dalam folikelgenesis.  Belum adanya bukti ilmiah efek konsumsi buah kurma muda terhadap reproduksi wanita mendorong dilakukannya studi ini. Studi ini bertujuan mengetahui kadar hormon FSH dan gambaran jaringan ovarium pada tikus setelah pemberian kurma muda.

Metode: Penelitian ini menggunakan desain ekperimental menggunakan tikus Sprague dawney betina sebanyak 28 ekor yang dibagi secara acak menjadi 4 kelompok. Kelompok I-III diberikan kurma muda dosis berturut -turut 17 mg, 34 mg, 68 mg per 200 gram BB dan kelompok IV diberikan aquadest. Perlakuan dilakukan selama 28 hari. Kadar hormon FSH diperiksa sebelum perlakuan saat fase proestrus yang diketahui dari pemeriksaan mikroskopis swab vagina tikus. Perlakuan dimulai saat fase proestrus.

Hasil: Rerata kadar FSH baseline dan paska perlakuan adalah 0,08 dan 0,09

Kesimpulan: Tidak terdapat peningkatan yang signifikan kadar FSH dan reseptor FSH terhadap efek pemberian buah kurma muda (Phoenix Dactylifera) pada uterus tikus Spague Dawney

Operational evidences on the engagement duty of Italian institutional investors
Authors: Drigo Francesco
Published: November 2019

Directive 2017/828 is the main legislative text of reference of the European Union (“EU”) in relation to the engagement duty of institutional investors (insurance companies, pension funds and asset managers) towards investee companies. This paper is intended to provide an overview of the engagement activities of Italian institutional investors and to outline possible developments with respect to local engagement practices. In general, evidence has shown a lack of activism by pension funds and domestic insurance companies, as well as the adoption of a selective/opportunistic approach by asset managers, mainly through collective engagement. Further, the Italian stock exchange showed a certain degree of proactivity in promoting the dialogue between issuer companies and investors. In this scenario, it may be worthy to investigate the opportunity for pension funds and insurance companies to exercise engagement activities in collective form as well.
Morphoanatomical study of Matricaria L. (Asteraceae) in Turkey
Authors: Inceer Huseyin , Bal Murat
Published: November 2019

In the Turkish flora, the genus Matricaria is present with four taxa, namely
M. aurea, M. chamomilla var. chamomilla, M. chamomilla var. recutita and M.
matricarioides. This study presents an evaluation of selected diagnostic
characters and anatomical traits of the achene (cypsela) of Matricaria in
Turkey using univariate analysis (one-way analysis of variance) and
multivariate analysis (cluster analysis, principal component analysis) to
obtain new information. Three groups are found within the genus Matricaria
based on morphoanatomical characteristics. The colour of disc florets, that
of ribs on the achenes, the presence or absence of a slime envelope and
pericarp thickness are useful for delimitation of Matricaria taxa, and a key
to taxa based on these characters together with other diagnostic traits is
provided.
Congeneric comparison of allelopathic and autotoxic effects of four Solidago species
Authors: Karpavicienė Birutė , Danilovienė Julija , Vykertaitė Roberta
Published: November 2019

The invasive species Solidago canadensis and S. gigantea are known for having
the potential to inhibit their neighbours through allelopathy. However,
there are no data on allelopathic properties of the natural interspecific
hybrid S. ?niederederi and no investigations comparing the allelopathic
potential of native and invasive Solidago species. We therefore studied the
allelopathic effect of aqueous leaf extracts of S. virgaurea, S. canadensis,
S. gigantea and S. ?niederederi on two congeneric pairs of species (Festuca
and Solidago) occurring naturally in communities with the tested Solidago
species. Germination and seedling growth of Festuca rubra were inhibited by
all Solidago extracts more than were those characteristics of F. pratensis,
while S. canadensis was more sensitive to its own and congeneric extracts
than was S. ?niederederi. The effect of leaf type (green or withered) on
Festuca seedling growth was target species-specific, while seed germination
was more suppressed by green leaf extracts. The results of this study do not
support the hypothesis that invasive plant species have stronger persistent
allelopathic effects on native plants compared to their native congeners.
Economics of row spacing and integrated weed management in soybean (Glycine max L.)
Authors: Daramola Olumide , Adeyemi Olusegun , Adigun Joseph , Adejuyigbe Christopher
Published: November 2019

The high cost of cultivation and weed management are major limiting factors
to increasing soybean productivity and net returns. Field experiments were
conducted in 2016 and 2017 at the Teaching and Research Farm of the Federal
University of Agriculture, Abeokuta to evaluate the economic performance of
different row spacings and integrated weed management system in soybean.
Three row spacings (50, 75 and 100 cm) as the main plots and six weed
control methods and a weedy check as sub-plot treatments were accommodated
in a split-plot arrangement of a randomized complete block design with three
replications. There was a significant reduction in weed biomass with a
reduction in row spacing from 100 cm to 75 cm and 50 cm. Furthermore, the
cost of production, grain yield and gross profit increased with a reduction
in row spacing from 100 to 75 and 50. When soybean was sown at 50-cm row
spacing, the application of Probaben 400EC (metolachlor 20% w/v + prometryn
20% w/v) or Butachlor 60EC (butachlor) at 2.0 kg a.i/ha each followed by
supplementary hoe-weeding at 6 weeks after sowing (WAS) resulted in the
highest yield of 2301-2484 kg/ha and total revenue of 2129-1972 $/ha.
Conversely, three hoe-weedings resulted in the highest yield of 2155-2081
kg/ha and total revenue of 1848-1783 $/ha for crops grown at 75- and 100-cm
row spacings. Despite the higher yield and revenue obtained with three
hoe-weedings for crops grown at 75- and 100-cm row spacings, the gross
profit and benefit-cost ratios obtained were lower than those obtained with
herbicide treatments applied alone or followed by supplementary hoe-weeding.
In terms of profitability, soybean planted at 50-cm row spacing and treated
with Probaben 400EC at 2.0 kg a.i/ha followed by supplementary hoe-weeding
gave the highest gross profit of 1479 $/ha. Two or three hoe-weedings in
soybean planted at narrow-row (50 cm) spacing did not guarantee the highest
yield, but rather increased the cost of weed control. This study suggests
that narrow-row spacing (50 cm) and pre-emergence herbicides will help to
reduce the number of hoe-weedings and consequently the high cost of
production required for optimum yield and increase profitability in soybean
production.
Comparative investment analysis of small-scale broiler and layer enterprises in Osun State, Nigeria
Authors: Baruwa Isiaka , Fabode Ololade
Published: November 2019

The study investigated the investment patterns, costs and return structures
of the layer and broiler production in Osun State, Nigeria. It also compared
their net present value in the study area to determine their investment
returns. A multistage sampling technique was employed in selecting
respondents for the study. Primary data were collected from 180 broiler and
layer farms, comprising 90 broiler farms and 90 layer farms from six local
governments in Osun State using a structured questionnaire. The data were
analysed using descriptive statistics, budgetary techniques and investment
tools. The investment pattern indicated that a larger amount of money was
invested in capital assets for small-scale layers (?651,274.5) compared to
broilers (?448,068.6). Personal saving was the major source of funding among
the small-scale layer enterprises compared to that of broiler enterprises.
In addition, the survival of re-investment in small-scale layers depends
largely on funds from family members while the small-scale broiler
enterprise depends on retained earnings. The budgetary analysis showed that
the gross margin of the farmers was ?166,321.8 and ?1,150,470.8 for broiler
and layer enterprises, respectively. Investment analysis revealed that the
layer enterprise had a higher positive net present value (NPV) and the
internal rate of return (IRR) value of ?1,523,692.6 and 64.9 per cent,
respectively. In contrast, the broiler enterprise had lower positive NPV and
IRR values of ?961,173.3 and 63.0 per cent, respectively. The study
concluded that the small-scale layer enterprise was found to be more
economically profitable compared to the small-scale broiler enterprise with
higher NPV and IRR values and a shorter discounted payback period in Osun
State.
Voluntary, Self-Regulatory, and Mandatory Disclosure of Oil and Gas Company Payments to Foreign Governments
Authors: Healy Paul M. , Serafeim George
Published: November 2019

SYNOPSIS

Concerns about high rates of government corruption in resource rich countries have led transparency advocates to urge oil and gas firms to disclose payments to host governments for natural resources. Transparency, they argue, can increase government accountability and mitigate corruption. However, we find a low frequency of voluntary disclosures of payments by oil and gas firms, and negative stock price reactions for affected firms at the announcement of regulations mandating disclosure. This suggests that sample firm managers and their investors perceive that such disclosures generate private costs, despite any public benefits. We document that industry self-regulation has generated information to substitute for the gap in voluntary company disclosure and that such disclosures are accompanied by lower country corruption ratings. This suggests that collective action could be an effective way for companies to manage the private costs of disclosure and respond to public pressure for transparency that could provide public benefits.

A versão longa do Questionário Internacional de Atividade Física, o Questionário de Barreiras para a Prática de Atividade Física, e o peso corporal/estatura, foram usados para avaliar o nível de atividade física, barreiras e índice de massa corporal. A amostra final foi composta por 205 participantes aposentados de ambos os sexos; em relação ao índice de massa corporal, os participantes apresentaram mediana de 26,9 kg/m², resultando em uma classificação como excesso de peso. Para o nível de atividade física no domínio lazer, 66,3% dos participantes se apresentaram insuficientemente ativos. E das 21 barreiras, nove apresentaram maior chance para o aumento do índice de massa corporal. Assim, torna-se importante ressaltar esses aspectos com relação à prática regular de atividade física, cujas barreiras podem ser transpostas se os profissionais e formuladores de políticas públicas implantarem programas voltados para esta população que visem ao incentivo dessa prática.

Humor Apto Todo Público. El cine de entretenimiento de Alberto Olmedo, Jorge Porcel y Enrique Carreras
Authors: Fidanza Fabio Nicolás
Published: November 2019

Los actores cómicos, Alberto Olmedo y Jorge Porcel, desarrollaron una extensa carrera que abarcó diversos medios y expresiones artísticas. Entre 1973 y 1988  la dupla realizó más de treinta películas para la productora Aries Cinematográfica. Si bien todas las películas que protagonizaron pueden considerarse comedias, no todas responden a las mismas características. A lo largo de sus carreras su obra fue transformándose dando origen a distintas variantes textuales. El objetivo de este trabajo es analizar las transformaciones que se dieron en los films protagonizados por esta dupla de cómicos, tanto a nivel textual como argumental, con el fin de dar cuenta del proceso de adecuación que llevó a cabo el dúo para responder a las necesidades de cada época. Analizaremos el tipo de humor que proponen estas comedias, así como también los personajes prototípicos y los roles de género que las películas proponen, y la relación que estas comedias tienen con la industria del entretenimiento nacional.

Complex nature of nitrogen fertilizer in soil and poor management practices are major causes of low fertilizer use efficiency in Pakistan. These factors further increases nitrogen losses in form of nitrate leaching and volatilization of ammonium, as well as nitric oxide which are burning economic and environmental threats. Keeping in view the demand of urea application in Pakistan and its low efficiency, we hypothized that appropriate urea management with neem formulations or biofertilizers can enhance the nitrogen use efficiency. We designed experiment with treatments: T0 (N0 application), T1 (recommended nitrogen), T2 (recommended nitrogen + biofertilizer), T3 (recommended nitrogen + neem seed extract), T4 (75% recommended nitrogen + biofertilizer), T5 (75% recommended nitrogen + neem seed extract), T6 (recommended nitrogen + biofertilizer + neem seed extract), T7 (75% recommended nitrogen + biofertilizer + neem seed extract) in wheat crop. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangements. Different approaches for stabilized nitrogen fertilizer responded significantly for the wheat plant height, tillers per plant, number of grains per spike, 1000-grain yield, grain yield and harvest index. Result exhibited that wheat crop enhanced yield attributes and finally the yield under treatment T6 and T7 for both wheat cultivars. Treatments comparison with recommended nitrogen (T1) revealed that all treatments with biofertilizer, as well as with neem seed, enhanced crop performance along with nitrogen use efficiency. It can be concluded that nitrogen fertilizer can be stabilized in the soil with the use of different natural products for sustainable crop production.

An effective reclamation procedure of saline sodic soils is removal of undesirable Na+ by addition of some Ca2+ source paralleled with leaching of this sodium out of root zone. Nevertheless, gypsum being a direct source of Ca2+ is relatively insoluble in water. Its solubility can be increased with addition of H2SO4. Therefore, three years (2015 to 2018) study was plan to find out the optimal and economical level of H2SO4, which can increase the solubility and reclamation efficiency of gypsum for saline sodic soil in rice wheat crop-ping rotation. Treatments included were: T1, Control, T2, gypsum @ 100% of GR, T3, gypsum @ 100% of GR+10 kg H2SO4 acre−1, T4, gypsum @ 100% of GR+50 kg H2SO4 acre−1, T5, gypsum @ 100% of GR+100 kg H2SO4 acre−1. Before start of study, soil had pHs = 8.85, ECe = 4.85 (dS m−1), SAR = 43.82 (mmol L−1)1/2, GR = 4.10 (t. acre−1), BD = 1.65 (Mg m-3), HC = 0.33 (cm hr−1). Experiment was laid out in RCBD with three replications. Sulfuric acid and gypsum were applied (once) at the start of study in the respective treatment plots. Recommended dose of fertilizers, 150-90-60 NPK kg ha−1 for rice (Shaheen Basmati) and 160-114-60 NPK kg ha−1 for wheat (Faisalabad, 2008) was applied. Yield and yield determining attributes of each crop were recorded at physical maturity. After harvest of each crop, soil samples were collected and were analyzed for ECe, pHs, SAR, bulk density and hydraulic conductivity. Pooled data analysis revealed that maximum growth and yield determining factors of rice and wheat were recorded where gypsum was applied with H2SO4 at the rate of 50 and 100 kg acre−1. Soil physical and chemical properties, i.e. pHs, ECe, SAR bulk density and hydraulic conductivity were also substantially improved with combined application of gypsum and H2SO4 at the end of study. Both levels of H2SO4 at the rate of 50 and 100 kg acre−1 with gypsum proved equally to be the best in enhancing the solubility and reclamation efficiency of gypsum and showed the statistically (p≤ 0.05) similar results in increasing the yield of rice and wheat crop and improving the soil physical and chemicals properties. Therefore, H2SO4 at the rate of 50 kg acre−1 is recommended as most economical and optimum level, which can be used with gypsum as an effective ameliorative strategy for the salt affected soils.
