Authors: Fu Becky Q , Zhong Claire CW , Wong Charlene HL , Ho Fai Fai , Nilsen Per , Hung Chi Tim , Yeoh Eng Kiong , Chung Vincent CH
Published: February 2023

Background: Avoidable hospital readmission is a major problem among health systems. Although there are effective peri-discharge interventions for reducing avoidable hospital readmission, successful implementation is challenging. This systematic review of qualitative studies aimed to identify barriers and facilitators to implementing peri-discharge interventions from providers’ and service users’ perspectives. Methods: We searched four databases for potentially eligible qualitative studies from databases’ inception to March 2020, and updated literature search for studies published between January 2020 to October 2021. Barriers and facilitators to implementing peri-discharge interventions were identified and mapped onto the Consolidated Framework for Implementation Research (CFIR) constructs. Inductive analysis of the CFIR constructs was performed to yield thematic areas that illustrated the relationship between various facilitators and barriers, generating practical insights to key implementation issues. Results: Thirteen qualitative studies were included in this systematic review. Key issues were clustered in the CFIR constructs of Design Quality and Complexity of the intervention, strength of Network and Communication, being responsive to Patient Needs with sufficient Resource support, and External Incentives. The three thematic areas were rationality of the interventions, readiness and effort of multidisciplinary implementation teams, and influence of external stakeholders. Common barriers included (i) limited resources, (ii) poor communication among team members, (iii) incompatibility between the new intervention and existing work routine, (iv) complicated implementation process, (v) low practicality of supporting instruments, and (vi) lack of understanding about the content and effectiveness of the new interventions. Common facilitators were (i) information sharing via regular meetings on implementation issues, (ii) organizational culture that values quality and accountability, (iii) financial penalties for hospitals with high avoidable readmissions rates, (iv) external support offered via quality improvement programs and community resources, and (v) senior leadership support. Conclusion: This study synthesized commonly-presenting barriers and facilitators to implementing peri-discharge interventions among different healthcare organizations. Findings may inform development of implementation strategies in different health systems after appropriate tailoring, based on a consensus-based formative research process.

Published: February 2023

Background: People with disabilities have experienced heightened social risks in the context of the pandemic, resulting in higher rates of infection and mortality. They have also borne elevated burdens associated with public health measures. The United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) obliges its 184 state parties to eliminate discrimination and ensure equality and inclusion for persons with disabilities, including protection and safety in situations of emergency. It remains unclear to what extent national COVID-19 policies have aligned with these commitments under the UNCRPD. Our objective in this exploratory study was to assess alignment between the UNCRPD indicators and COVID-19 policies from 14 countries with the goal of informing policy development that is inclusive of persons with disabilities and responsive to rights under the UNCRPD. Methods: We identified COVID-19 policy documents from 14 purposively selected countries. Country selection considered diversity based on geographic regions and national income levels, with restriction to those countries that had ratified the UNCRPD and had English or French as an official language. We used a computational text mining approach and developed a complex multilevel dictionary or categorization model based on the UNCRPD Bridging the Gap indicators proposed by the Office of the High Commissioner on Human Rights (OHCHR). This dictionary was used to assess the extent to which indicators across the entirety of the UNCRPD were represented in the selected policies. We analyzed frequency of associations with UNCRPD, as well as conducting ‘key word in context’ analyses to identify themes. Results: We identified 764 COVID-19 national policy documents from the period of January 2020 to June 2021. When analyzed in relation to the Articles of the UNCRPD, the most frequently identified were Articles 11 (risk and humanitarian emergencies), 23 (home and family), 24 (education), and 19 (community living). Six countries produced 27 policies that were specifically focused on disability. Common themes within these documents included continuation of services, intersectionality and equity, and disability considerations in regulations and public health measures. Conclusion: Analyzing country policies in light of the UNCRPD offers important insights about how these policies do and do not align with states’ commitments. As new policies are developed and existing ones revised, more comprehensive approaches to addressing the rights of persons with disabilities are urgently needed.
Regulatory Reforms for Health Facilities: Can These Suffice?; Comment on "What Lies Behind Successful Regulation? A Qualitative Evaluation of Pilot Implementation of Kenya’s Health Facility Inspection Reforms"
Authors: Bagonza Arthur , Musoke David , Wamani Henry
Published: February 2023

In their study on how Joint Health facility Inspections (JHI) were implemented in practice with a need to identify key facilitators or barriers for regulatory policy and practice, Tama et al found that innovative regulatory reforms markedly improved inspection scores among intervention health facilities albeit with challenges. Their article makes an important contribution to the body of knowledge in as far as regulation of health facilities is concerned. In low- and middle-income countries, private health facilities are poorly regulated and yet, they purge gaps where public health facilities are inadequate as was demonstrated during the COVID-19 pandemic. Therefore, while regulation of public health facilities is standardized, the research by Tama and colleagues provides a unique opportunity to continue dialogue on how private health facilities can be regulated through inspection and supervision. Regulation of public and private health facilities continues to be contentious since both experience unique contextual challenges.
Toward Universal Health Coverage: Regional Inequalities and Potential Solutions for Alleviating Catastrophic Health Expenditure in the Post-poverty Elimination Era of China
Authors: Luo Yanan , Shi Zhenyu , Guo Dan , He Ping
Published: February 2023

Background: This study took Beijing as an example to estimate the incidence and regional inequalities of catastrophic health expenditures (CHE) in a megacity of China. Methods: This study used data from the Health Services Survey Beijing (HSSB) 2018. Logistic regressions were used to investigate the risk factors for experiencing CHE, and concentration curves, the concentration index and its decomposition method based on probit models were used to estimate the inequalities in CHE. Results: CHE occurred in 25.51% of the households of the outer suburb villages, 6.78% of the households of the inner-city area communities, 17.10% of the households of the villages of the inner-city areas, and 11.91% of the households of the communities of the outer suburbs. In areas in the outer suburbs, households with private insurance coverage were associated with a lowered risk of CHE, and lower educational attainment and lower occupational class were related to an increasing risk of CHE. This study also discovered pro-rich financing disparities in CHE in Beijing, with the outer suburbs having the highest levels of CHE disparity. When it comes to the observed contributions of disparities in CHE, a significant portion of them is connected to the sorts of occupations, educational levels, and residential status. Conclusion: The impoverishment brought on by medical expenses and CHE must still be taken into account in the post-poverty elimination era. The megacity of China was discovered to have significant regional differences in the incidence of pro-rich financing inequity in CHE. Disparities in socioeconomic status (SES), one of the controllable variables, may be a key area to address to lower the risk and minimize CHE inequality in megacities towards the path to UHC. Additionally, it is important to consider the financial protection impact of inclusive supplementary medical insurance on lowering the likelihood of CHE in the periphery areas.
Policy Vs Business: Well-Designed Health-Related Food Policy Should Not Let Industry Marketing Undermine Its Intended Effects; Comment on "Understanding Marketing Responses to a Tax on Sugary Drinks: A Qualitative Interview Study in the United Kingdom, 2019"
Authors: Cornelsen Laura , Cuevas Soledad
Published: February 2023

Health-related food policies, such as taxes on unhealthy food and drink, can act as catalysts for food industry to take action which may or may not align with the policy goal of improving population health. This commentary discusses the framework proposed by Forde et al (2021) in analysing the food industry marketing responses to the Soft Drink Industry Levy (SDIL), implemented in the UK in 2018. We suggest and discuss ways which may help broaden the use of the framework to other relevant policies. This includes widening the framework to cover strategies that may have not come up within the SDIL context but have been studied in other contexts. It would also be important to consider interactions between the strategies and with external factors influencing company decisions. Going forward, comprehensive evaluations of health related policies should consider likely interactions with industry marketing strategies to fully understand potential impacts.
Contextual Factors That May Impact on the Development and Implementation of the Sugary Drinks Policy; Comment on "Understanding Marketing Responses to a Tax on Sugary Drinks: A Qualitative Interview Study in the United Kingdom, 2019"
Authors: Chilet-Rosell Elisa , Lumbreras Blanca
Published: February 2023

Forde et al proposed an interesting framework to understand marketing response to a tax in sugary drinks based on stakeholder interviews. Sugary drinks regulation can lead to various strategies in the industry’s marketing activity. That is, it can either result in the industry introducing no changes or it can lead to changes, which can conflict or align with public health objectives. The importance of Forde et al.’s analysis lies in the potential for governments to anticipate the industry’s reaction to the legislation and the need of drivers to enable both big and small companies to follow the rules. Governments must not forget the importance of other contextual factors that will have an impact both on the development and implementation of this type of policies and on possible responses that could mitigate their impact such as public acceptance, the influence of mass media and corporate activities aimed at influencing policy.
The Evolution of External Healthcare Regulation in England; From Performance Oversight to Supporting Improvement; Comment on "The Special Measures for Quality and Challenged Provider Regimes in the English NHS: A Rapid Evaluation of a National Improvement Initiative for Failing Healthcare Organisations"
Authors: Lalani Mirza , Hogan Helen
Published: February 2023

The Special Measures and Challenged Provider (SMCP) Regime introduced for struggling healthcare organisations in England represents a subtle shift to the scope of external regulation from performance oversight to include supporting internal service improvement. External regulation alone has a had a mixed impact on the quality of care and Vindrola-Padros et al’s study highlights that externally driven improvement initiatives may also struggle to succeed in turning around performance. Principally, this is due to a failure in acknowledgment that poor performance results from a myriad of external and internal factors which coalesce to impede organisational performance. A struggling organisation may be indicative of wider issues in the local health and care system. Whole systems approaches to improvement with collaboration across providers and the effective use of data may support struggling organisations but their role maybe tempered with the increased centralisation of the delivery of improvement regimes such as SMCP.
Exploring the Components of a Comprehensive Model Governing Successful Marriages: A Qualitative Study
Authors: Jokar Habib , Yousefi Zahra , Torkan Hajar
Published: February 2023

Background: A successful marriage is a dynamic growing relationship in which both partners continue to grow to achieve personal satisfaction. Building a successful life depends on a successful marriage. Therefore, this study aimed to explore the components of a comprehensive model governing on-time marriages among Iranian married men. Methods: This study was conducted using a qualitative thematic analysis approach. Using a homogeneous purposive sampling method, 14 married men in Bushehr were selected and interviewed. The collected data were analyzed using the content analysis method. Results: The analysis of the data from the interviews revealed three main categories related to on-time marriage among men including having a family that supports marriage, a marriage loving character, and the conditions facilitating marriage. Conclusion: Following these findings, it can be argued that a successful marriage depends on three important components of personality, requirements, and family supporting the on-time marriage. Thus, the improvement of marital life also depends on multidimensional corrections made by taking into account these factors. Accordingly, some measures need to be taken to promote marriage among young people and make them interested in marriages. Furthermore, families need to support their children and provide facilities for them to have successful and on-time marriages. Finally, social institutions and officials are required to facilitate conditions for people to have successful marriages.

Published: February 2023

Background: Nurses who care for patients with coronavirus disease 2019 (COVID-19) face challenges in providing care for these patients. This study aimed to explain the nurses’ perception of challenges in caring for patients with COVID-19. Methods: This study was carried out using the content analysis method in 2020. In this study, 28 nurses were selected via purposive sampling. Individual and semi-structured interviews were conducted to collect the data. Data collection continued until data saturation. Content analysis was used to categorize the data and the method proposed by Elo and Kyngäs was also applied to analyze the data. Results: Nurses’ challenges were classified into three categories including organizational problems, defective communication process, and psychosocial challenges. The first category was divided into two subcategories including shortage of nurses and lack of personal protective equipment. The second category included two subcategories of defective communication with colleagues and defective communication with the patients and their families. Moreover, the third category was classified into two subcategories including psychological distress and sociocultural challenges. Conclusion: To address the challenges of nurses in caring for patients with COVID-19, the shortage of nurses should be eliminated. Nurses need to participate in comprehensive communication skills training courses. Furthermore, it is necessary to develop educational programs and present them to the public based on the cultural context of the society.

Background: Cardiac patients are prone to experiencing constipation. The main purpose of the present study was to assess the effect of acupressure on preventing constipation in patients with acute myocardial infarction (AMI) under primary percutaneous coronary intervention. Methods: The present randomized clinical trial was conducted on 90 patients with AMI (30 patients in each group) who were randomly allocated based on inclusion criteria. The intervention was carried out among the patients with AMI on the acupressure points SJ6, LI4, ST25, and SP6 two times a day (10 am and 6 pm) for three sequential days. Results: On the first and second days of the study, all of the patients had no defecation, and the first defecation occurred on the third day of the study. In the intervention, sham, and control groups, 93.3%, 46.7%, and 50.0% had normal defecation on the third day of the study, respectively. The results of the Chi-square test revealed significant differences among the three groups (P<0.001). Conclusion: The results of the present study showed that patients with AMI in the intervention group had significant improvement in terms of stool consistency based on the Bristol stool scale. So, acupressure can be used as a nursing intervention in critical care units.
Laparoscopy-Assisted Endoscopic Retrograde Cholangiopancreatography: New Insight in Management of Iatrogenic Bile Duct Injury
Authors: Emara Mohamed H , Elbatae Hassan E. , Ali Reda F , Ahmed Mohammed H. , Radwan Mohamed Said , Elhawary Abdulhamid
Published: February 2023

Bile duct injury (BDI) is a severe and sometimes life-threatening complication of cholecystectomy. Several series have described a 0.5% to 0.6% incidence of BDI during laparoscopic cholecystectomy. We received an emergency call from the operating theater by the surgery team to assess an iatrogenic BDI in a 58-year-old man with cirrhosis who presented for laparoscopic cholecystectomy. After many trials by endoscopic retrograde cholangiopancreatography (ERCP) the guide wire passed to the peritoneal cavity and failed to pass proximally. Laparoscopy resumed, and the surgeon tried to pass the flexible guide wire proximally unsuccessfully. Then, a decision to hold the sphincterotome by laparoscopy and passing it proximally in harmony with ERCP was taken, which was successful. A regular ERCP with 10F plastic stent insertion was carried out, and the perforation was secured by the inserted stent without any further surgical intervention. Laparoscopy-assisted ERCP may give new insights into the immediate repair of iatrogenic bile duct injuries.

The Monetary Economics of the Austrian School and the Chicago School
Authors: Salin Pascal
Published: February 2023

To what extent is there complementarity or agreement between Austrian economics and the Chicago school on monetary issues? Both Austrians and Chicagoans would agree that monetary expansion has real effects in the short run, though they emphasize different variables. In the long run, Austrians argue that there is a lasting real effect of monetary expansion—money is not neutral—but Chicagoans too argue that economic activity is less efficient even if people correctly forecast the rate of inflation. Regarding the balance of payments, both the Austrian and Chicago school lead to the conclusion that there can be no balance-of-payments problem. Both are modern versions of the classical price specie flow theory. Perhaps the Austrian approach to monetary economics and the Chicago school approach are more compatible than is commonly thought.
A Note on Money Neutrality
Authors: Dorobat Carmen Elena
Published: February 2023

Although Pascal Salin’s desire to build bridges between the Austrian School and the Chigago School, as well as his efforts to smooth out the differences between schools of monetary thought, is admirable, it is difficult to see the need or the urgency to integrate the Austrian approach with other approaches. Salin has not yet made a convincing case that the Austrian approach to monetary issues is lacking, and indeed, there are several reasons why such reconciliation between the two traditions is impossible.
Comment on Salin’s “The Monetary Economics of the Austrian School and the Chicago School”
Authors: Gertchev Nikolay
Published: February 2023

Well-intended and richly argued as Salin’s proposal for reconciliation between the Austrian School and Chicago School is, it eschews a discussion of one aspect of the two schools that is also relevant to their respective monetary views; namely, their analytical method. This short comment aims to clarify why the specific praxeological approach of the Austrian school makes its monetary theory unique. By implication, as long as methodological differences between the Austrian and the Chicago traditions persist, no reconciliation will be within reach. This comment concludes that this is the decisive, though unintended, contribution of Salin’s article.

Published: February 2023

LoRa technology in Indonesia is currently in the development stage to accelerate the digitalization of cheap and reliable connectivity-based smart utilities. Palabuhanratu is a potential area for LoRa network infrastructure development due to the density of end devices in Palabuhanratu which causes the process of sending data on a network to be hampered. The parameters used in the LPWA software simulation include Signal Level, Noise to Interference Carrier Level and Link Budget. This research method analyzes the simulation results on Signal Level, Noise to Interference Carrier Level and Link Budget as parameters for the construction of LoRa network infrastructure at a frequency of 920-923 MHz in Palabuhanratu. The research is divided into two planning stages. The first planning stage is the calculation of capacity and calculation of coverage. The second planning stage is simulation using Atoll Low Power Wide Area software. The results of the simulation analysis obtained in this study are that there are 10 gateway capacities using the Atoll application software. The average values generated by the simulation parameters include the Signal Level, which is -64.06 dBm with the ”good” category based on the KPI standard, which is more than - 80 dBm and the Noise to Interference Carrier Level parameter of 27.71 dB which is included in the ”excellent” category, namely greater than 12 dBm in KPI standardization, and the resulting path loss is -107.74 dBm at a cell radius of 1.261 km.

Methodisches Handeln in der Sozialen Arbeit
Authors: von Spiegel Hiltrud
Published: February 2023

"Berufliches Können" braucht zentrale, auch wissenschaftlich begründbare Arbeitsregeln. Oft fehlt Praktikern, aber auch den Studieren das Rüstzeug für die Planung und Nachbereitung ihrer Arbeit. Berufliches Handeln erfolgt überwiegend intuitiv und mit Rückgriff auf Erfahrungen und Routinen. Ob und warum dieses aber in einer gegebenen Situation angemessen ist, bleibt unklar.
Das Buch zeigt hier Auswege auf, indem es Anregungen für ein systematisch geplantes und am wissenschaftlichen Vorgehen orientiertes methodisches Handeln bietet. Es begründet und beschreibt Arbeitshilfen, die die berufliche Handlungsstruktur und die für Soziale Arbeit relevanten Wissensbestände in einen reflexiven Zusammenhang bringen.
A Submillimeter-Wave FMCW Pulse-Doppler Radar to Characterize the Dynamics of Particle Clouds
Authors: Bryllert Tomas , Bonmann Marlene , Stake Jan
Published: February 2023

This work presents a 340-GHz frequency-modulated continuous-wave (FMCW) pulse-Doppler radar. The radar system is based on a transceiver module with about one milli-Watt output power and more than 30-GHz bandwidth. The front-end optics consists of an off-axis parabola fed by a horn antenna from the transceiver unit, resulting in a collimated radar beam. The digital radar waveform generation allows for coherent and arbitrary FMCW pulse waveforms. The performance in terms of sensitivity and resolution (range/cross-range/velocity) is demonstrated, and the system's ability to detect and map single particles (0.1–10 mm diameter), as well as clouds of particles, at a 5-m distance, is presented. A range resolution of 1 cm and a cross-range resolution of a few centimeters (3-dB beam-width) allow for the characterization of the dynamics of particle clouds with a measurement voxel size of a few cubic centimeters. The monitoring of particle dynamics is of interest in several industrial applications, such as in the manufacturing of pharmaceuticals and the control/analysis of fluidized bed combustion reactors.
On the Possibility of an Event
Authors: Schwartz Daniel
Published: February 2023

This paper introduces a concept of possibility that may be applied to
real-world events that are viewed as having prerequisites that must be
satisfied in order for the event to occur and/or constraints that may
impede or prevent the event’s occurrence. The core idea is to compute
the possibility of the event as a function of the probabilities that the
prerequisites are satisfied and the constraints are not, and where this
function computes possibility values of logical combinations of
prerequisites and constraints according to the principles of fuzzy
logic. Thus, this notion of possibility is a hybrid of fuzzy logic and
probability theory. It has the advantage that it provides an objective
procedure for determining the possibility of an event insofar as the
probabilities of the prerequisites and constraints may be determined by
statistical samplings. This version of possibility would appropriately
be applied to problems of planning. When there are multiple plans
available for achieving a goal, this theory can be used to determine
which plan is most possible, i.e., easiest or most feasible to complete.
It is speculated that this model of reasoning more correctly captures
normal human reasoning about plans. This may be contrasted with the pure
use of probability theory, which can be used to determine which plan is
most likely to succeed, but is not typically employed by humans in their
everyday decision making.
RGB-D Visual Odometry via Low Order Gaussian Gradient Metrics
Authors: Yao Zhigang , An Xu , Charrier Christophe , Rosenberger Christophe
Published: February 2023

This paper gives a direct Visual Odometry (VO) of RGB-D cameras by using features conducted with low-order  Gaussian derivative functions such as Gaussian gradient operator. By using the feature metrics locally, it improves further possibilities for sampling more reliable points from scenarios that are lack of structure or texture and is beneficial to continuous tracking. The proposed approach reaches relatively acceptable performance with a globally heuristic framework built on the general coarse-to-fine and inverse compositional estimation. Experimental results are conducted on a group of TUM datasets for validating the proposed approach.
MSC-PoL: Hybrid GaN-Si Multistacked Switched Capacitor 48V PwrSiP VRM for Chiplets
Authors: Wang Ping , Chen Yenan , Szczeszynski Gregory , Allen Stephen , Giuliano David , Chen Minjie
Published: February 2023

This paper presents a multistack switched-capacitor point-of-load (MSC-PoL) voltage regulation module (VRM) with coupled magnetics for ultrahigh-current chiplet systems. In the MSC-PoL architecture, the stacked switched-capacitor cells split the high input voltage into several intermediate voltage rails, which are loaded with the switched-inductor cells to achieve soft charging and voltage regulation. Automatic capacitor voltage balancing and inductor current sharing are realized during the soft charging process. Many inductors of the switched-inductor cells are coupled into one and operated in interleaving to reduce the inductor current ripple and boost the transient speed. A 48-to-1-V/450-A VRM containing two MSC-PoL modules is built and tested, leveraging high voltage GaN devices for the front-end and high current Silicon devices for the back-end. Two ladder-structured coupled inductor designs are developed and compared, one of which installs a leakage magnetic plate to adjust the leakage inductance for lower current ripple. Featuring 3D stacked packaging, the entire power stage, gate drivers, and bootstrap circuits of one MSC-PoL module are enclosed into a 1/16-brick/0.31-in3/6-mm-thick package. The peak and the full-load efficiencies as well as the full-load power density (including both gate loss and size) of the MSC-PoL prototype with and without using the leakage plate are 91.7% and 89.5%, 85.8% and 85.6%, and 621 W/in3 and 724 W/in3, respectively. The 6-mm-thick MSC-PoL converter can be embedded into the chiplet or CPU socket, enabling power-supply-in-package (PwrSiP) for extreme efficiency, density, and control bandwidth.
A Novel Incipient Slip Degree Evaluation Method and its Application in Adaptive Control of Grasping Force
Authors: Sui Ruomin , Zhang Lunwei , Huang Qiyin , Li Tiemin , Jiang Yao
Published: February 2023

Grasping is the most basic and important function of robots. However, the grasping performance of existing manipulators is far inferior to that of human hands. Human hands are able to evaluate the degree of incipient slip on contact surface based on tactile information during grasping process and thus regulate grasping force. As a result, humans can use the smallest possible grasping force while ensuring successful grasping, which maximizes the performance of their hands and avoids damaging the grasped object as much as possible. The existing incipient slip degree evaluation methods have certain shortcomings. So this paper proposes a novel method which can be applied to complex contact conditions where the incipient slip degree is not unidirectional and torque exists. Also, there are no restrictions on the material parameters and surface topography of the grasped object, and no need to obtain any information about it in advance. We construct a grasping force control strategy for parallel grippers based on this evaluation method, with the goal of enabling the gripper to achieve the similar grasping performance of human hands. The grasping strategy is verified in simulations and actual experiments, and the difference between the controlled force and minimum grasping force is demonstrated
