Background: Around the world, providing holistic nursing care and ensuring patient satisfaction have become crucial health-care performance indicators. Despite a lot of efforts to improve patient satisfaction with nursing care, the approach in the developing world, including Ethiopia, is still insufficient.
Objective: The aim of this study was to assess adult patients’ satisfaction with nursing care services and identify the factors affecting satisfaction at Saint Paul’s hospital millennium medical college, 2022.
Methods: Cross-sectional study was conducted at Saint Paul’s hospital millennium medical college. A simple random sampling technique was used to select 422 study participants. The actual sample was distributed using proportional allocation for each selected adult inpatient departments. Participants were interviewed using a modified structured Amharic version of ‘Newcastle Satisfaction with Nursing Scale’ tool from June 20/2022 to July 30/2022. Data analysis was made by SPSS version 26. Bivariate and multivariable logistic regression analysis was used to identify factors associated with adult patient satisfaction. Statistical association was declared using 95% CI and a p-value of < 0.05.
Results: The overall level of patient satisfaction with nursing care was 54.3%. Respondents who had no formal education (AOR=8.482; 95% CI=1.678-42.87), being male (AOR=2.487; 95% CI=1.038-5.959) (P-value=0.041), free service consumers (AOR=6.650; 95% CI: 2.677-16.517), health insurance user (AOR=7.309; 95% CI=3.122-17.110) (P-value=0.000), was significantly associated with satisfaction with nursing care. In addition patients’ who had admission history (AOR=0.261; 95% CI=0.122-0.560), governmental workers (AOR=0.090; 95% CI=0.026-0.310) (P-value=0.000) and patients admitted in medical ward (AOR=0.160; 95% CI=0.039-0.649) (P-value=0.010) were associated with patient dissatisfaction with the nursing care services.
Conclusion and recommendations: The finding showed that patient satisfaction with nursing care was rated low. Admission history, higher education level, paid cash for service, private and governmental workers were significant predisposing factors to dissatisfaction with nursing care. On the other hand, patients who had no formal education, free service consumers, and being male were significant predictors of satisfaction with the nursing care services. Therefore, it is recommended to include all communities with health insurance schemes and the hospital administration to better give emphasis to patient needs and expectations.

Asian weaver ant, Oecophylla smaradigma is a nuisance species, effect the plantation employee due to their painful bites. The O. smaragdina was reported as one of the potential predators for the invasive bagworm species, Pteroma pendula in the oil palm plantation. Despite their important role in the plantation, however the study on the ecology and behaviour of the O. smaragdina is still lacking and not discovered. The objectives of this study were to investigate the relationships between the foraging daily activities of the O. smaragdina with the weather parameters. In 2018-2022, this study investigates the trunk foraging activity pattern of O. smaragdina colonies (9 days per colony) from selected plantations, as an effort of mitigation. In 2020-2022, a targeted field study was undertaken to examine the daily trunk foraging activities of major workers in relation to air temperature (AT), relative humidity (RH), air pressure (AP) and rainfall (RI). Ground forager behaviours were observed and examined from the trunk trail split covering an average frontal fluctuating angle from base palms. It is suggested that O. smaragdina is a diurnal ant species with much lesser crepuscular intensity. It is demonstrating similar daily foraging activity patterns featuring higher intensity during the warmest daily periods in relation to population size relative abundance. This was irrespective of the dry-wet seasons corresponding to low activity from late scoot-phase to early photo phase, exhibiting a bimodal foraging pattern. Throughout the overnight period, foraging activity ceased. O. smaragdina is a visual light dependent hunter for efficient intensive foraging. Active foragers reached peaks at around 1100 to 1530 hours, and from 1745 to 1845 hours. Between 1620 and 1650 hours, foragers demonstrated a two-fold daily decline in intensity on average. There was a strong positive correlation between foraging activity, AT and AP but negatively correlated with RH. Sustained RI stopped the trunk-ground trail activity of O. smaragdina, exposing outbound foragers withdrawing massively to the canopies. Defensive territorial layers are established from the base palm trunks reaching an average 5 m distance featuring two distinct spatial arrangements. Major workers trunk trails split into several new lines on an average 3 m radius showing higher foraging density. The trails broke off to expand into a web shape figure occupation reaching on average 5 m. The avoidance of forager relentless attacks can be achieved during the daily low activity periods (before 1000 hours) for pruning and harvesting tasks if the adoption of O. smaragdina is implemented to control the invasive Metisa plana bagworm species.

Published: November 2022

Skin cancer is a major health concern, with 125,000 new melanoma cases diagnosed each year. Every year, approximately 3 million non-melanoma cases are diagnosed worldwide. Initially, skin lesions were diagnosed visually using dermoscopic analysis, clinical screening, and a variety of other methods. It has been observed that inexperienced dermatologists can reduce the diagnostic accuracy of skin lesions. Early detection of skin cancer has the potential to reduce mortality. Previous research has shown that deep learning outperforms human experts in a variety of computer vision tasks.
This paper proposes to develop an ensemble deep learning model to detect skin cancer from lesion images.In this analytical investigation, 10,000 photos from the HAM10000 dermoscopy image database were used, comprising lesions with and without melanoma.The photos were divided into different skin cancer classifications using a number of deep convolutional neural networks.VGG16, VGG19, and ResNet were used as the pre-trained models in an ensemble deep learning approach.
The area under the receiver operating characteristic (ROC) curve for the suggested model was 0.91. A classification accuracy of 86%, sensitivity of 81%, and specificity of 88% were attained using a confidence score threshold of 0.5.
Detecting skin cancer, including melanoma and non-melanoma tumors, has a high potential according to the results of deep learning. Dermatologists can identify skin cancer with the use of the indicated method.As a result, it might hasten cancer detection, which is essential for efficient therapy. The suggested model automatically extracts useful features from the input raw image for categorization.It does away with difficult lesion segmentation and feature extraction processes as a result.

Authors: Bai JianGuo , Yang Hai
Published: November 2022

N6-methyladenine is an epigenetic modification that plays a significant role in various cellular processes. Genome-wide monitoring of methylation sites is conducive to understanding the biological function of methylation. Due to the limitations of traditional dry and wet experiments, a series of machine learning and deep learning methods have been developed to detect methylation sites, but their detection species are single or performance is poor. First of all, we conducted sufficient experiments on the widely studied rice datasets, and compared with the previous research, we have greatly improved in various indicators on the two rice datasets. Then we used the models trained on the rice dataset to fine-tune training in half of the other 11 datasets and predict the other half of the independent datasets. Then we used 11 trained models to test 11 species respectively. It was found that ACNN-6mA could obtain higher AUC, ACC and MCC whether cross-species prediction or independent verification set prediction. ACNN-6mA model and code for follow-up researchers is provided as an open-source tool available at https://github.com/jrebai/ACNN-6mA.

Background: Tramadol is a centrally acting synthetic analgesic, chemically related to morphine and codeine. Tramadol abuse is being used by many people with different adverse effects; most likely seizures, and respiratory depression. Some men use tramadol for erectile dysfunction. We report a case of tramadol-induced intracerebral hemorrhage.
Case report: A 36-year-old male with no history of chronic diseases presented to the emergency department with a sudden onset of left-sided weakness. He had no other conventional vascular risk factors such as hypertension, diabetes, or dyslipidemia. A neurological examination showed right gaze preference and mild right facial droop with left-side hemiplegia, and the left Babinski sign was positive. He denied smoking cigars or consuming khat, and he had no family history of stroke. Routine vital signs were normal. The electrocardiogram was normal. And routine blood investigations were normal. NIH Stroke Scale = 22 when he came in. A CT head showed a 53x24 mm hemorrhage in the right basal ganglia region. He had an MRI angiogram, which showed normal intracranial and extracranial vessels. The patient confirmed that he had been using tramadol for two years due to erectile dysfunction.
Conclusion: A previously healthy middle-aged male with no vascular risk factors developed a hemorrhagic stroke. It was reported that he had been using tramadol for two years. So, the patient developed the right basal ganglia due to tramadol addiction. It is the first time in the literature that tramadol-induced intracerebral hemorrhage has been reported.

Published: November 2022

The usability and usefulness of smartphones have been found to lack optimality. Moreover, the action of the customer appears to behave as a consumptive user instead of buying following the basic needs. In selecting the right smartphone, this study provides an alternative option for buyers. The Fuzzy Analytical Hierarchy Process (F-AHP) approach is applied by distinguishing between two distinct decision-making namely, Profile User as a user recommendation-based, and Smartphone-based selection. The suggested requirements are hobbies, areas of jobs, and the use of social network applications in determining the user profile. The weights of the criteria and alternatives for profile users are acquired through the dissemination of questionnaires to 117 respondents. In the meantime, parameters such as Random-Access Memory (RAM), Read-Only Memory (ROM), camera, processor, screen, and battery are added to the smartphone list of criteria upon on the interviews of 15 experts and practices in smartphone and Information Technology (IT). F-AHP rates each of the Smartphone and User Profiles as a first-round output. A rule-based expert system is employed to intertwine Smartphone and User Profiles decision-making viewpoints. The relationship between the Smartphone and the User Profile is therefore circumscribed as the final decision to applaud the acceptable Smartphone for those users of the profile. A prototype of the MatchSmartPhone application has been developed to computerize the F-AHP calculation. This application can be used to assist users according to the user's profile in delivering the best Smartphone device recommendations. Users would be wiser and smarter when shopping in advance.
Stabilizing the Laughlin state of light: Dynamics of hole fractionalization
Authors: Kurilovich Pavel , Kurilovich Vladislav D. , Lebreuilly José , Girvin Steven
Published: November 2022

Particle loss is the ultimate challenge for preparation of strongly
correlated many-body states of photons. An established way to overcome
the loss is to employ a stabilization setup that autonomously injects
new photons in place of the lost ones. However, as we show, the
effectiveness of such a stabilization setup is compromised for
fractional quantum Hall states. There, a hole formed by a lost photon
can separate into several remote quasiholes none of which can be
refilled by injecting a photon locally. By deriving an exact expression
for the steady-state density matrix, we demonstrate that isolated
quasiholes proliferate in the steady state which damages the quality of
the state preparation. The motion of quasiholes leading to their
separation is allowed by a repeated process in which a photon is first
lost and then quickly refilled in the vicinity of the quasihole. We
develop the theory of this dissipative quasihole dynamics and show that
it has diffusive character. Our results demonstrate that
fractionalization might present an obstacle for both creation and
stabilization of strongly-correlated states with photons.

hine Muscat, with its excellent quality and unique Muscat aroma, is emerging as one of the most profitable table grape cultivars in Asia. However, in-depth analysis of the cultivar’s aroma profile before berries are harvest-ready is lacking. The aroma components and their concentrations undergo substantial changes during berry ripening, which provides an opportunity for producing some juice/wine products with special flavour. In this study, the evolution of free and bound aroma compounds in Shine Muscat grapes was analysed from EL-35 to EL-38. The main aroma attributes of harvest-ready berries were: ‘green’, ‘sweet’, ‘floral’ and ‘fruity’. The headspace SPME-GC-MS analysis revealed that alcohols were the most abundant free and bound compounds in Shine Muscat. Furthermore, the free forms of hexanal, β-damascenone, and (E, Z)-2,6-nonadienal determined the aroma characteristics of the grapes directly, while the bound forms of β-damascenone, (E, Z)-2,6-nonadienal, and 2-hexanol determined the aroma of Shine Muscat that cannot to be smelled directly. Taking all indicators together, we believe that picking Shine Muscat grapes at EL-37 (when a minimum TSS of 17% has been reached) maintains its fine aroma characteristics. These results lay the foundation for the further development, utilisation and study of the aroma characteristics of Shine Muscat grapes.

Published: November 2022

Being a water-scarce country, South Africa (SA) faces several water challenges, including drought and other effects of climate change. Therefore, there is a need to improve water-use efficiency (WUE) by accurately quantifying the water use and WUE of table grape vineyards. The objective of this review is to (i) provide an overview of water footprint (WF) studies conducted on table grape production systems in SA and globally; (ii) identify limitations in current WF assessments of table grape production systems; and (iii) establish a range of WF values for table grape production systems as an indicator of WUE and for use in decision-making regarding sustainable freshwater use. The review has demonstrated that only a limited number of detailed WF studies have been undertaken on table grapes in SA and globally. Region-specific lookup tables for quantifying blue, green and grey water use in table grape production systems are available for three table grape production regions of SA and could be used for future WF assessments. Most global studies conducted on grape WF and WUE were desktop studies and did not include actual field records from production units, nor did they distinguish between different grape types (table, raisin and wine grapes). WF values must be interpreted in context, specifically regarding the water used versus yield, quality and income, as well as the region, climatic conditions, soil characteristics, irrigation and cultivation practices. For future WF and WUE assessments, a more detailed breakdown of water use is recommended, both during the production process and postharvest.

Published: November 2022

Quercetin solubility at 18 °C and 0 °C was determined in an hydroalcoholic buffer solution with pH 3.20 and in four Italian wines to study the formation of quercetin precipitate mechanism in wines. The wines selected were Barbera 2018 for the typically high content in bisulfite bleachable pigments, red Cirò 2014, for its typically high content of flavonoids, Sangiovese 2014, for the presence of quercetin deposits in bottle, and white Cirò 2018, for the absence of red pigments. All the samples were spiked with 30 mg/L quercetin. The amount of quercetin solubilized at 18 °C and 0 °C in the hydroalcoholic buffer was much lower than in wines, while that solubilised in Barbera was much higher compared to red Cirò, Sangiovese and white Cirò. Solubilised quercetin was lower in all wine samples stored at 0 °C than in those at 18 °C. The pigment composition of the three red wines examined suggested that the over-solubility of quercetin could be due to the formation of soluble co-pigmentation complexes between quercetin and monomer anthocyanins and/or bisulphate-bleachable flavanol-anthocyanin pigments. A positive correlation between quercetin solubility and bleachable pigment was noted: the richer the wine in bleachable pigments, the higher the solubility of quercetin. Quercetin haze formation appeared due to the release of quercetin from co-pigmentation complexes during wine maturation and storage ,as its counterpart, anthocyanins, form non-bleachable pigments or are degraded in hydrolytic or oxidation reactions. Quercetin in aged red wines seemed to reach a content similar to that of white wine spiked with quercetin. Nevertheless, the quercetin content of aged red wines in which a quercetin haze has been found could be lower than that when added white wine, due to its degradation probably being induced by oxidation reactions. Finally, the solubilized quercetin content in white Cirò, which was higher than the hydroalcoholic buffer solution, suggested that there may be different substances in wines than pigments that prevent the growth of quercetin crystals. However, their nature was not determined in this study.
The Promise of Using Protoplasts in Grapevine Research
Authors: Derman S. S. , Vivier M.A.
Published: November 2022

Protoplasting refers to the isolation of protoplasts from plant material. These protoplasts are cells bound only by their plasma membranes following the removal of their cell walls. In grapevine research, protoplasting efforts and successes have been reported from 1985 onwards, but recent research has shown a renewed focus on grapevine-derived protoplasts, particularly due to the possibility of using protoplasts in applications such as gene-editing approaches. Grapevine species are generally considered recalcitrant to manipulation in culture and have also proven recalcitrant with regards to protoplasting and particularly in the regeneration of plants from protoplasts. This review will highlight the important milestones in grapevine protoplasting while outlining the current efforts to establish grapevine protoplasting as a routine technique.

Published: November 2022

OBJECTIVE: To investigate the glycemic status of pregnant women by the comparison of 50 g glucose challenge test results and body mass index changes in the pandemic period versus last year's test results.
STUDY DESIGN: In this case-control study two groups were constituted. Group 1 included patients who underwent a glucose challenge test in the year 2019 before the pandemic lockdown (n=604) was assessed as the control group; group 2 (n=505) included patients who underwent the same test in the year 2020 that in the pandemic lockdown period was evaluated as the study group.
RESULTS: Pandemic lockdown affected the gaining weight in every level of educational status who did not exercise, but there was only a statistical difference between university-educated participants. We could not see any negative effect of the pandemic lockdown on glucose challenge test results. But only in the university-educated participants, there was an effect on increased glucose challenge test levels.
CONCLUSION: Our study and the other studies designed like ours show that the pandemic lockdown affects our life worse.
Removal of dissolved organic matter in road runoff by granules prepared using sludge from waterworks
Authors: Du Xiaoli , Tian Dianxi , Yin Zijie , Chen Mengyao
Published: November 2022

This work assessed the elimination of dissolved organic matter (DOM) in road runoff by a granular sludge-clay (GSC) adsorbent. The rates of adsorption were found to be consistent with the pseudo-second-order kinetic model. The data at equilibrium resulted in a maximum adsorption capacity of 4.466 mg/g at 298 K, which was in good agreement with the Langmuir isotherm model. The adsorption of DOM relies on pH. The higher removal efficiency of DOM was observed at pH 4.0 and 7.0. To clarify the related adsorption mechanism, isolated DOM fractions and their removal potentials were identified. The results showed hydrophobic acid (HoA) and hydrophobic neutral (HoN) fractions which contained abundant fulvic-like substances were more preferentially removed by the GSC. The adsorption mechanism of DOM in road runoff by GSC involves both electrostatic attraction and ligand exchange reactions. GSC synthesized using the sludge from waterworks is a very promising filler to replace soils or gravels that can be applied in some green infrastructures for removing DOM from road runoff.
Study of the physical clogging mechanism of sandstone geothermal tailwater recharge
Authors: Wang Jianzhong , Wang Xiangtao , Xu Qingfa , Tian Suo , Huang Yue
Published: November 2022

An important part of geothermal development is the re-injection of waste geothermal fluids into the reservoir, which can extend the life of the geothermal resource. However, the difficulty of recharge and the clogging problem in the recharge process are still a worldwide problem that restricts the sustainable development and utilization of sandstone geothermal reservoirs. The main factor affecting the recharge effect is physical clogging. In this paper, a series of simulation experiments were conducted to study the physical clogging in the recharge process of sandstone thermal storage in the Lubei area, which conclude that the degree of clogging is related to the particle size and concentration of suspended matter. At a certain particle size, the clogging is most serious when the experimental suspended matter concentration gradient is up to 140 mg/L. In addition, particle migration in clogging is related to the recharge flow rate, and the critical flow rate is 0.75–2 mL/min, which is experimentally derived, and it is recommended that the recharge rate should be controlled below 0.75 mL/min during the actual recharge. This paper provides a scientific basis for the efficient recharge of geothermal tailwater through the study of the clogging mechanism.
Study of sewage oxygenation treatment based on gas magnetization mechanism
Authors: Zhao Keli , Wu Hui , Zhao Xianghe , Liu Yuqi , Yu Aiwei , Man Zunhai
Published: November 2022

In the process of sewage treatment, the sewage usually needs to be aerated, so the oxygenation efficiency is an important indicator for the aerator. The general oxygenation technique is to inject large amount of natural air into the aeration tank over long time, which has lower efficiency and leads to dramatic waste of energy. Based on the gas-liquid fusion mass transfer model and combined the oxygen enrichment mechanism by magnetization of the gas into the aerator, a novel method to improve the efficiency of wastewater oxygenation is proposed. This method is based on the fact that oxygen and nitrogen exhibit completely different magnetic characteristics in gradient magnetic fields, and then the special shaped permanent magnets can be used to build a target gradient magnetic field to increase the oxygen content as the gas is injected into the sewage by the aerator, which reaches the oxygenation enhancement effect. Through theoretical analysis and experiments, it is concluded that the efficiency of sewage oxygenation treatment is dramatically improved with the permanent magnet oxygen enrichment technique.
Funding the High-Speed Rail: A Case Study of the California Project
Authors: Chandra Shailesh , Mishra Vivek
Published: November 2022

Introduction:

High-speed rail (HSR) projects are considered high-stake investments– both in construction, operation, and maintenance. Thus, HSR requires financing from various sources - public, private or a mix of both, as the case maybe. Traditional funding for HSR has usually been the public funds through various bonds and taxes. However, public funds are not easy to come by and are usually subjected to strict audits and reviews. Therefore, alternative funding sources are always sought after, especially those that are sustainable.

Methods:

A multiobjective optimization problem is proposed in this paper encompassing revenue generation, accessibility maximization and workforce-centric access measure (WAM) consideration for financing HSR development costs and justifying its purpose. The procedure identifies key HSR stations that could be developed and improved to positively increase revenue collected through taxes on surrounding properties that appreciated due to the HSR, or the appreciation that either occurred through accessibility increase or WAM considerations from the HSR.

Results and Discussion:

Such key stations that score high in one or more of these considerations could be considered for further development by policymakers and planners. Based on the multiobjective optimization problem proposed in this paper, and with the California HSR as an example, the three proposed stations of San Francisco Transbay Terminal, University City and Downtown Merced are recommended to be developed and improved to attract economic growth with the HSR line.

Conclusion:

The findings could help authorities focus on these stations (and similar others) for a sustainable means of at least partially funding California’s HSR project.

The study was a quasi-experimental study that employed both qualitative and quantitative methods of data collection. An all-inclusive sampling method was used to select all 72 volunteers for a pre-exercise medical evaluation, and questionnaires were administered to 600 volunteers for pre and post-data. The respondents were treated with a six-week dose of regular daily selected physical activities. The post-test was conducted, recorded, and subjected to statistical analysis using inferential statistics.

Results:

The mean age was 18±1.89 with the age of 17 forming the largest group, i.e., 218 (36.3%). Females, 379(65.2%), were slightly more than their male counterparts, 221 (36.8%). The results of pre-exercise showed that some, 9 (12.2%), had normal body temperature. The respondents who were obese and over-weighted were 25 (33.8) and 20 (27.1), and respondents with high mean arterial pressure were 15 (20.3), respectively. The mean arterial pressure (MAP) of the respondents tested showed no significant difference (P>0.05) between the mean age, sex and marital status with respect to the blood sugar level, body temperature and the body mass index. MAP and irregular participation in physical activities were significant (P<0.05) among this group of students. The knowledge mean score (KMS) of 19.37±6.035 was high compared to a 27-point scale. There was no significant relationship between df=2, F=1.566 and P>0.005. Some, 160 (26.7%), had excellent overall physical health, and 173 (28.8%) had good overall physical health. There were significant interactional effects (F= 59.276, mean score within group 1.60, df 2, p = .000, R = -282) between groups and time for perceived benefits, interpersonal norms, social support, counter heart conditioning, stimulus control, and overall time spent on being physically active per week.

Conclusion:

In conclusion, a correlation was observed between the predictive factors and cardiovascular diseases; it was recommended that all students should be encouraged to engage in regular PE at a level appropriate to their capacities, needs, and interests to maintain optimal cardiovascular health status.
Overcoming High Cardiovascular Disease Burden in Indonesia: The Importance of Massive Cardiovascular Disease Risk Factor Screening, Aggressive Guideline-Directed Treatment, and Community-Based Programs
Authors: Waranugraha Yoga
Published: November 2022

Indonesia is a developing country with a large number of populations. Cardiovascular disease (CVD) is a serious public health concern in Indonesia because of its high burden. Moreover, the high-risk CVD patients were under treatment. Optimal CVD prevention can be the solution to this issue. In this paper, we are talking mainly about the role of massive CVD risk factor screening, precise risk stratification, aggressive guideline-directed treatment, and community-based programs in reducing the CVD burden.

Authors: Ari Nugraha Khrisna , Widito Sasmojo , Satrijo Budi , Kurnianingsih Novi
Published: November 2022

Background: Percutaneous coronary intervention for bifurcation lesions remains challenging because of its complexity and the lack of trials to guide decision-making. It also comes with several debatable issues, including the requirement for kissing balloon inflation as the post-dilation produces. Case Illustration: A 64-year-old male with some coronary risk factors of hypertension, passive smoker, and family history of CAD presented with recurring exertional chest pain for the last 4 months. He was hospitalized to undergo DCA-Adhoc after the ECG stress test revealed a positive result. The coronary angiography revealed a 95% ISR in the osteal LAD and 20% ISR of the proximal LCx. Since the patient refused to undergo coronary bypass surgery, the team decided to perform catheter intervention to the LM bifurcation of LAD-LCx. The procedure begins with the insertion of IABP through the access of the left femoral artery. We performed a provisional approach with the main vessel stenting of LM-LAD. At the end of the procedure, we performed simultaneous kissing balloon inflation of LAD-LCx followed by POT in LM stent as the post-dilation produces. Discussion: When considering intervention on a bifurcation lesion, there are two general strategies i.e the more conservative or provisional technique that intent to only use one stent and the two-stent approach. The provisional technique is considered to offer advantages in terms of reducing procedure complexity, reducing fluoroscopic time, requiring less contrast volume, and reducing resource (stent) use compared by 2 stent strategy. Conclusion: Coronary bifurcation lesions are fairly frequent, and their management is associated with an increased risk of MACE, increased complexity, and prolonged treatment times.
Alternative capital asset depreciation rates for U.S. capital and total factor productivity measures
Authors: Giandrea Michael D. , Kornfeld Robert J. , Meyer Peter B. , Powers Susan G.
Published: November 2022

The U.S. Bureau of Economic Analysis (BEA) and the U.S. Bureau of Labor Statistics (BLS) use estimates of depreciation rates for structures and equipment to construct estimates of capital stock from data on capital investments. The depreciation rates are based on research by Frank C. Wykoff and Charles R. Hulten from the 1980s. More recent studies by Statistics Canada, from 2007 and 2015, use Canadian data on used asset transactions from Canada’s Annual Capital and Repair Expenditures Survey of establishments. They found faster depreciation rates, especially for structures. Sheharyar Bokhari and David Geltner’s 2019 study of U.S. used asset prices also found faster depreciation rates for structures. To illustrate the potential effects of implementing these estimates from newer studies, we created a concordance to match Canadian to U.S. asset categories. We reestimated BEA capital stock measures and the BLS capital and total factor productivity (TFP) measures using depreciation rates based on the Canadian Annual Capital and Repair Expenditures Survey. Using these faster depreciation rates results in substantially lower estimates of net capital stocks and higher estimates of depreciation in BEA accounts but has minimal effects on growth rates of TFP in the BLS accounts.
Is there a digital divide in eHealth? A cross-sectional survey of middle-aged and older residents in rural Shandong, China (Preprint)
Authors: Shi Wenjie , Zhang Yaru , Fu Wenhao , Wen Wen
Published: November 2022

BACKGROUND

Although eHealth is an important way to alleviate the imbalance in the distribution of medical resources, the utilization rate of eHealth services is low, especially in rural areas.

OBJECTIVE

The primary purpose of this study was to explore the factors that discourage the use of eHealth services, with middle-aged and older rural residents with medical service utilization over the past year as the research subjects, to identify targeted measures to bridge the digital divide.

METHODS

Although eHealth is an important way to alleviate the imbalance in the distribution of medical resources, the utilization rate of eHealth services is low, especially in rural areas. The primary purpose of this study was to explore the factors that discourage the use of eHealth services, with middle-aged and older rural residents with medical service utilization over the past year as the research subjects, to identify targeted measures to bridge the digital divide.

RESULTS

We found that 6.53% of the sample had used eHealth services. After controlling for confounding factors, years of education, self-rated health status, and local and non-local experience in Grade-A tertiary hospitals were positively correlated with the use of eHealth services. In contrast, age was negatively associated with the use of eHealth services.

CONCLUSIONS

There was a digital divide in the use of eHealth services among people aged 45 years or older in rural China with real medical use. Older, less healthy, and less educated middle-aged and older rural Chinese individuals were vulnerable groups of eHealth utilization. The government should improve eHealth adoption and make members at different stages of development benefit from the dividend brought about by eHealth.

BACKGROUND

Prediction models are increasingly utilized in clinical practice but the optimal approach to collecting the needed inputs is unknown.

OBJECTIVE

Our objective was to compare a mortality prediction model inputs and scores based on chart abstraction versus patient survey.

METHODS

Older patients with type 2 diabetes at an urban, Chicago primary care practice were recruited and the Lee Mortality Index was calculated from retrospective chart review and patient surveys.

RESULTS

We saw non-significant differences in mortality scores (p=0.61) and subsequent diabetes in older adult health status class recommendations (p=0.70) comparing chart abstraction to survey data. However, there were large differences in certain domains such as functional status and presence of disease. Differences in chart review and survey resulted in 20% having discordant diabetes recommendations.

CONCLUSIONS

Healthcare organizations should work to systematically and routinely collect PROs that are inputs for widely used prediction models.

Review of Introduction to Cognitive Pragmatics
Authors: Du Juan
Published: November 2022

This article reviews the book—Introduction to Cognitive Pragmatics written by Klaus-Uwe Panther. The book is a synthetic attempt to blend a cognitive linguistic approach to language in use from contemporary pragmatics. Although a few works on this reconciled filed have been published in the past 30 years, the term Cognitive Pragmatics is not well established in linguistic community yet (Schimid, 2012). In this vein, this newly published book makes a few steps forward on the road to an interface study approach both on cognitive linguistics and pragmatics. This review introduces and analyzes the main content of the book as well as providing a critical comment.
