PI-based PLL and 24-sector control of a 3P-3L-NPC inverter for grid-tied PV system synchronization
Authors: Ammari Sakina , Benaboud Aziza , Talea Mohamed
Published: September 2022

This article addresses one of the most serious issues in electricity: frequency and voltage anomalies. Actually, because renewable energy production is intermittent, the frequency and voltage of electricity produced are unstable and dependent on weather conditions. This issue causes industrial processes to fail, affecting the quality of the electrical supply and having a massive economic impact. Power electronics inverters are designed to compensate for system fluctuations in solar power generation. However, measurement noise in the grid voltage desynchronizes the inverter and network signals. The authors propose using a phase-locked loop technique based on inverter period control and a network voltage observer to achieve such synchronization of grid-connected photovoltaic (PV) systems. In this work, the grid integration of the PV system is carried out through a three-phase three-level neutral point clamped inverter due to better current quality with fewer harmonics and lower stress voltage of the inverter's components when compared to two-level voltage source inverters. The method is successfully applied in a simulated case study and experimental results validate it.
A new bee species of the genus Dasypoda Latreille (Hymenoptera, Apoidea) from Northwest Africa with comparative remarks on the subgenus Microdasypoda Michez
Authors: RADCHENKO VLADIMIR G. , GHISBAIN GUILLAUME , MICHEZ DENIS
Published: September 2022

North Africa, with its vast array of ecosystems and reliefs, constitutes a remarkable place to explore and describe the diversity of wild bees. In this paper, a new bee species of the genus Dasypoda Latreille (Hymenoptera, Apoidea, Melittidae), D. schwarzi Radchenko et Michez sp. nov., is described from the Atlas Mountains area (Morocco and Tunisia). This species belongs to the subgenus Microdasypoda Michez and is phenotypically related to D. brevicornis Pérez, but differs from all other species of this subgenus by the structure of the male genitals, the metasomal sterna, and by its overall hair colour. A detailed comparative diagnosis of D. schwarzi with the other four species of this subgenus is provided, as well as a key to the males of Microdasypoda, and a correction to the diagnosis of the subgenus. This new species is the fortieth described Dasypoda species and should be looked for in other mountain regions of Northwest Africa, such as in the Algerian Atlas where it could be present.
Robust fractional order PID controller synthesis for the first order plus integral system
Authors: Zheng Weijia , Chen YangQuan , Wang Xiaohong , Lin Meijin , Guo Jing
Published: September 2022

The fractional order PID (FOPID) controller has been found to have the potential to provide more flexibility in the design options than the integer order PID (IOPID) controller. However, in the FOPID controller design practice, investigations are still required in selecting the achievable design specifications and controller parameters. In order to obtain a practical tuning method for the FOPID controller, taking the first order plus integral systems as the plants, the complete achievable regions of the design specifications are collected and analyzed. In addition, the selectable integral and derivative orders of the FOPID controller are also collected and modeled. With the prior knowledge obtained, a synthesis method for the FOPID controller is proposed to make the control system achieve the desired flat-phase characteristic. To verify the effectiveness of the proposed method, the synthesis method is applied to design the FOPID controller for the permanent magnet synchronous motor (PMSM) speed servo system. Simulation and experimental results show that system with the FOPID controller can achieve satisfying tracking performance and disturbance rejection performance.
Integrating Social, Political and Commercial Determinants of Health Frameworks to Advance Public Health in the twenty-first Century
Authors: Freudenberg Nicholas
Published: September 2022

Existing frameworks seek to elucidate the social, political, and commercial determinants of health in order to inform practice, policy, and research that can improve health and reduce health inequities. Each approach has widened the scope of public health practice and research and identified new partners and targets for intervention. But as the public health crises of the past decade have shown, these frameworks have not yet yielded insights that have enabled the public health profession and movement to prevent or overcome dominant threats to global health and health equity. This report explores the value of an integrated framework that combines insights from previous scholarship and practice using the social, political, and commercial determinants of health. It proposes the questions such an integration would need to answer and suggests processes and tasks that could lead to the creation of a blended framework.
The shame of truth – death due to accidental autoerotic asphyxia
Authors: Mileva Biliana , Goshev Metodi , Alexandrov Alexandar , Gitto Lorenzo
Published: September 2022

Autoerotic deaths occur in the context of sexual activity when different devices and objects are used to increase stimulation and sexual pleasure, resulting in unintentional deaths. A common feature of autoerotic deaths s the presence of a self-rescue mechanism to ensure survival and escape a dangerous situation. By definition, autoerotic deaths are accidental. Thus, it is essential to exclude suicide or homicide. An atypical case of autoerotic asphyxia is presented, in which the victim showed a ligature mark produced by a soft belt with maximum pressure on the posterior aspect of the neck and the point of suspension located anteriorly. A detailed scene investigation and the autopsy findings helped determine the manner of death. Determining the manner of death in AADs can be challenging and has a significant legal, social, and economic impact. A multidisciplinary approach is required to reach the correct conclusion. We present a case of AAD with atypical findings.
Adaptation and validation of BullyHARM-China—a Chinese version of the Bullying, Harassment, and Aggression Receipt Measure
Authors: Yang Jingyi , Ferraz Raul , Shi Dexin , Harrison Sayward E. , Ye Zhi , Chen Lihua , Lin Danhua
Published: September 2022

Bullying is a growing concern in China, yet there are few validated scales designed to measure different types of bullying among Chinese children. In this present study, a bilingual team of researchers use a forward-backward translation process to adapt the Bullying, Harassment, and Aggression Receipt Measure (BullyHARM) for Chinese youth. BullyHARM has previously been shown to be a reliable scale for measuring six bullying domains (i.e., physical, verbal, social/relational, cyber, property, sexual) among children in the United States (US). After cultural and linguistic adaptation, we enrolled 397 middle school students from Beijing, China in a validation study to assess the psychometric properties of the new BullyHARM-China scale. Results of confirmatory factor analysis suggest the final 21-item scale displays strong internal consistency. Consistent with findings from the US, the first-order model of six factors (i.e., six bullying subscales) displays the best fit to the data. Our findings suggest that BullyHARM-China is a reliable tool for measuring bullying victimization among Chinese students.
When public administration education switches online: Student perceptions during COVID-19
Authors: Rawat Stuti , Yan Yifei , Wu Alfred M , Vyas Lina
Published: September 2022

Public administration education is traditionally known for its emphasis on interaction, discussion and experiential learning, which require effective in-person instructions. With COVID-19 pushing many programmes across the globe to be delivered online rather than in person, how this shift has affected the student experience in public administration programmes has been a pertinent and important consideration. This paper addresses the question through two surveys of 147 students in total, at a graduate-level public policy school in Singapore. Two distinctive waves of data collection allow us to capture a nuanced picture of student perceptions both when online teaching was introduced as an emergency response and when it was planned as a deliberate strategy later on. Our findings suggest that students consistently reported a decline in participation and interaction in an online setting, compared with a face-to-face setting. Our study fills a critical gap in the literature related to online public administration education in Asia, while the immediate constraints it highlights and lessons it offers on maintaining a highly interactive and engaging public administration education are likely to apply for educators elsewhere both during and beyond the COVID-19 era.
Isolated Kaposi sarcoma of the upper aerodigestive tract in immunocompetent individuals, an underrecognized entity with favorable prognosis
Authors: Shabaan Abdelrahman , Alkashash Ahmad , Hou Tieying , Saeed Omer , Yesensky Jessica , Roshal Anna , Mesa Hector
Published: September 2022

Kaposi sarcoma (KS) is a rare vascular neoplasm that most commonly arises in the setting of immunosuppression, in areas with high prevalence of Human Herpesvirus-8 infection, and when both situations coexist. Most cases affect the skin, isolated involvement of the upper respiratory tract without skin involvement is extremely rare with only a few cases reported in the literature. We present a case of isolated nasopharyngeal KS in an immunocompetent patient who achieved remission after multimodality therapy. Recent advances in KS-therapy are discussed.
Attenuation-Corrected Estimators of Reliability
Authors: Metsämuuronen Jari
Published: September 2022

The estimates of reliability are usually attenuated and deflated because the item–score correlation ([Formula: see text], Rit) embedded in the most widely used estimators is affected by several sources of mechanical error in the estimation. Empirical examples show that, in some types of datasets, the estimates by traditional alpha may be deflated by 0.40–0.60 units of reliability and those by maximal reliability by 0.40 units of reliability. This article proposes a new kind of estimator of correlation: attenuation-corrected correlation ( R AC): the proportion of observed correlation with the maximal possible correlation reachable by the given item and score. By replacing [Formula: see text] with R AC in known formulas of estimators of reliability, we get attenuation-corrected alpha, theta, omega, and maximal reliability which all belong to a family of so-called deflation-corrected estimators of reliability.
The health of mothers of children with a life-limiting condition: A qualitative interview study
Authors: Fisher Victoria , Atkin Karl , Fraser Lorna K
Published: September 2022

Background:

The number of children with a life-limiting condition is increasing. The mothers of these children commonly provide extensive care at home for their child and are at a higher risk of poor health than other mothers. The impact of this is rarely explored from mothers’ perspectives.

Aim:

To explore mothers’ accounts of their physical and mental health, experiences of accessing healthcare and who they think should support their health.

Design:

Qualitative semi-structured interviews were conducted and analysed using thematic analysis.

Setting/participants:

Thirty mothers of children with a life-limiting condition were recruited via three UK children’s hospices and social media.

Results:

Mothers felt that their health concerns could be misunderstood by professionals, describing untimely and inappropriate support that failed to recognise the nature of caring for a child with a life-limiting condition. This led to mothers’ reluctance in addressing these concerns. Mothers felt unable to prioritise their own needs, relative to those of their child and worried about who would look after their child if they did become unwell. They described stress as a result of battles with services rather than as a result of caregiving. Mothers valued feeling recognised as caregivers, which made it easier to look after their health alongside their child’s. Hospice support was particularly valuable in this respect.

Conclusions:

A more unified system that recognises not only the unique set of challenges presented to mothers caring for a child with a life-limiting condition, but the value of palliative care services in supporting these mothers, is required.
Influence of the area of the aqueduct and region of interest on quantification of stroke volume in healthy volunteers using phase-contrast cine magnetic resonance imaging
Authors: Zhang Hongri , Yang Haixin , Duan Weike , Li Xiaopan , Wang Yixin , Cogswell Petrice M , Elder Benjamin D
Published: September 2022

Background

Phase-contrast cine magnetic resonance imaging (PC-MRI) has been used to measure cerebrospinal fluid (CSF) flow dynamics, but the influence of the area of the aqueduct and region of interest (ROI) on quantification of stroke volume (SV) has not been assessed.

Purpose

To assess the influence of the area of the ROI in quantifying the aqueductal SV measured with PC-MRI within the cerebral aqueduct.

Material and Methods

Nine healthy volunteers (mean age = 29.6 years) were enrolled in the study, and brain MRI examinations were performed on a 3.0-T system. Quantitative analysis of the aqueductal CSF flow was performed using manual ROI placement. ROIs were separately drawn for each of the 12 phases of the cardiac cycle, and changes in aqueduct size during the cardiac cycle were determined. The SV was calculated using 12 different aqueductal ROIs and compared with the SV calculated using a fixed ROI size.

Results

There was variation in the size of the aqueduct during the cardiac cycle. In addition, the measured SV increased with a greater area of the ROI. A significant difference in the calculated SVs with the 12 variable ROIs was observed compared with that using a fixed ROI throughout the cardiac cycle.

Conclusion

To establish reliable reference values for the SV in future studies, a variable ROI should be considered.
The Contributions of Social Stressors and Coping Resources to Psychological Distress Among Those Who Experienced Furlough or Job Loss Due to COVID-19
Authors: Grace Matthew K.
Published: September 2022

The COVID-19 pandemic precipitated a global economic recession resulting in widespread unemployment and worker furloughs. Using national survey data (n = 2,000), this study examines whether and how employment-based discrepancies in financial strains, anticipatory stressors, and personal coping resources contribute to elevated psychological distress among those who experienced involuntary job displacement due to COVID-19. Disaggregating displaced workers into those who were furloughed and those who lost their job due to the pandemic, I find that both groups report more depressive symptoms and anger than the stably employed and respondents whose unemployment is not COVID-related. Greater financial strains and smaller reserves of coping resources contribute in varying degrees to heightened levels of distress found among displaced workers, however, anticipatory stress about economic security is the predominant factor driving disparities in psychological distress. These findings, and the central role of anticipatory stressors in shaping employment-based differences in mental health during the pandemic, are discussed.
Upper Limb Onabotulinumtoxin A Injections in Children Under 2 Years with Cerebral Palsy: A Retrospective Chart Review
Authors: Centorame Danni , Rawicki Barry , Hennel Sabine , Hoare Brian
Published: September 2022

Aim: To report on the safety of using Onabotulinumtoxin A (OnaA) in the upper limb(s) of children <2 years of age with cerebral palsy and to describe a proactive clinical model of care in the management of upper limb impairment in children with cerebral palsy. Methods and procedures: Retrospective chart audit of 65 infants aged 13-23 months (mean 18.69) who received upper limb OnaA injections. Administration procedures, trends in muscle selection, and adverse events were examined. Results: Adverse events were reported in 6 (4%) of the 65 children. Across the study period, muscles that control thumb and forearm movements were most commonly injected. The number of OnaA injections to subscapularis and flexor digitorum profundus increased over this period. Conclusions and implications: OnaA is a safe treatment option for the short-term management of focal upper limb muscle overactivity in children under 2 years of age with cerebral palsy. In line with existing evidence, OnaA should always be considered as an adjunct to evidence-based therapy.
Investigation through novel tool-electrode feeding approach on electrochemical discharge machining of glass
Authors: Santra Sudip , Sarkar Biplab Ranjan , Doloi Biswanath , Bhattacharyya Bijoy
Published: September 2022

The electrochemical discharge machining (ECDM) process is a promising advanced machining process to remove material from electrically non-conductive materials like glass, ceramics, etc. Till now fabricating a channel with a high aspect ratio on the glass surface is a challenging job as the generated gas bubbles are escaped from the machining area without developing gas film and consequent discharges. In this study, two novel approaches of tool feeding such as side feeding and bottom feeding along with usual top feeding approach have been introduced to keep the gas bubbles at the tool-electrode tip so that the development of gas film and spark discharge are taken place uniformly at the machining zone. Tool-electrode feeding at the bottom surface and at the side surface of workpiece have been employed and compared with the usual top feeding tool-electrode at the top surface of workpiece. The concentration of aqueous sodium hydroxide electrolyte and the feed rate of tool are varied for experimental investigations. The side feeding of tool-electrode has been found as the most suitable feeding approach for ECDM process. During side feeding approach, the overcut of the machined channel has been reduced by 11% as compared to that of top feeding. Also, depth of the channel has been increased significantly during machining by side feeding and bottom feeding. The tool wear has been reduced more in case of side tool-feeding approach than other two tool-feeding approaches.

Authors: Venkata Ramana Challa Veera , Sarvjeet Dubey Raghavendra
Published: September 2022

An low-voltage, solution-based spin cast-processed two-terminal bi-stable memory device was fabricated by using organic-inorganic-organic tri-layer structure (MEHPPV/ZnO/MEHPPV) onto indium tin oxide coated glass. Tri-layer device structure displayed the significant switching characteristics. The absence of degradation after 1 h retention test at 120 °C was noticed. The consistent memory behavior was noticed even after 50 cycles. Electron tunneling mechanism was utilized for describing switching mechanism of the device. The result emphasizes that the class of memory devices have been fabricated with organic-inorganic-organic nanocomposites, which has led to considerable research and development efforts to the scene of latent applications.
Leaving home: Technological and landscape knowledge as resilience at pre-Holocene Kharaneh IV, Azraq Basin, Jordan
Authors: Macdonald Danielle A , Maher Lisa A
Published: September 2022

Humanity’s relationship with the environment during the Holocene, and into the Anthropocene, is structured around our dependance on agricultural production, which has resulted in risk mitigation strategies that include intensive landscape modifications, among other tactics. However, to understand broader patterns of human resilience and the shifts in human/environment relationships, we need to look further back in time. Through this paper, we explore cultural strategies of risk management and resilience in pre-Holocene communities and how these practices allowed hunter-gatherer communities to adapt to a changing environment. For over 1000 years, the Epipalaeolithic site of Kharaneh IV was a focal point on the landscape for hunter-gatherer groups, acting as an aggregation site for Early and Middle Epipalaeolithic peoples. Located in the eastern desert of Jordan, at the time of occupation the site was a lush wetland surrounded by a rich grassland environment, providing abundant food and other resources for the site’s occupants. However, over time the wetland began to dry up and by 18,600 cal BP Kharaneh IV was abandoned. In this paper, we discuss the final occupation of Kharaneh IV, linking the site’s abandonment to the increasing aridification of eastern Jordan. Environmental change led to the eventual abandonment of Kharaneh IV and other nearby sites, as people relocated within the Azraq Basin in search of new water resources during the Holocene. Flexible technological strategies and knowledge of the landscape created resilient cultural practices that allowed these communities to use population movement as a risk management strategy.

Authors: Corebima Brigitta I.R.V. , Sulistijono Eko , Akmaly Triyana D.D. , Sinatra Talita Clarissa
Published: September 2022

Caring for preterm infants in the intensive care unit can lead to a variety of conditions that increase stress and pain during routine care procedures. One of the intensive care unit procedures is diapers usage and change. The immature anatomical and physiological growth and development, especially the musculoskeletal system, neurological system, and integumentary system, is a challenge in the care of premature infants. Inappropriate diapers in premature infants can result in neurodevelopment problems, diaper dermatitis, and long-term postural disorders. Supportive care in the intensive care unit should include maintaining sleep cycles, creating a comfortable environment, periodic stress and pain measurement, practicing infants’ skincare, and care involving parents.
Comparison of anti-Müllerian hormone and inhibin immunolabeling in canine and equine granulosa cell tumors
Authors: Nelissen Sophie , Miller Andrew D.
Published: September 2022

Granulosa cell tumors (GCTs) are common ovarian neoplasms in the mare and bitch that can be challenging to diagnose on histopathology. Inhibin has long been the standard immunohistochemical (IHC) marker for GCTs; however, anti-Müllerian hormone (AMH) has not been evaluated widely as an IHC marker in the bitch and mare. We compared the efficacy of AMH and inhibin as IHC markers in canine and equine GCTs. We selected retrospectively 18 equine and 15 canine cases. All equine tumors were dominated by a cystic pattern; canine tumors often had solid patterns. Both inhibin and AMH had similar punctate cytoplasmic patterns of immunolabeling, although labeling intensity was variable; distribution and intensity of labeling were unrelated to the histomorphologic pattern. Labeling for AMH occurred in 12 of 15 canine and 18 of 18 equine cases. Labeling for inhibin occurred in 15 of 15 canine and 18 of 18 equine cases. AMH in equine GCTs often had stronger immunolabeling than inhibin, and granulosa cells were labeled more extensively. Inhibin and AMH performed comparably in bitches, but AMH had more diffuse immunolabeling than inhibin in mares.

Published: September 2022

Objective

To evaluate the sensitivity to change of daily ratings of the comfort (COMF) and behavioral/emotional health (BEH) domains of the Infants with Clefts Observation Outcomes Instrument (iCOO) at 3 time points, and to assess the association of post-surgical interventions on iCOO ratings.

Design

The COMF and BEH domains were completed by caregivers before (T0), immediately after (T1), and 2-months after (T2) cleft lip (CL) surgery. Analyses included descriptive statistics, correlations, t-tests, and generalized estimating equations.

Participants

Caregivers ( N  =  140) of infants with CL with/without cleft palate.

Main Outcome Measures

The COMF and BEH domain scores of the iCOO: Scale (SCALE), a summary of observable signs; and Global Impression (IMPR), a single item measuring caregivers’ overall impression.

Results

Daily COMF and BEH SCALE and IMPR scores changed significantly during T1 ( P's < 0.001) but not T0 or T2. Day 1 and 7 T0 scores were significantly higher than Day 1 and 7 T1 scores ( P's <0.001 to <0.012) but similar at T2 ( P's > 0.05). After CL surgery, the combined use of immobilizers and nasal stents and the use of multiple feeding methods with treatment for gastroesophageal reflux were associated with lower daily scores in COMF and BEH SCALE and IMPR ( P's: 0.040 to <0.001).

Conclusions

COMF and BEH iCOO scores were sensitive to daily changes in infant well-being following CL surgery. Future studies should further investigate impact of post-surgical treatments on infant well-being.
Using Structural Family Theory in Treating Family Conflict
Authors: Pender Baum Rebecca L. , Pender Debra A.
Published: September 2022

This article outlines the current research on the treatment of family conflict, structural family theory (SFT), and the application of SFT in the treatment of family conflict. Family therapy is rarely conducted with violent families because of state-mandated programs that focus on the individual perpetrator. Yet, structural family therapy has much potential for addressing power, boundaries, and transactions associated with family violence. The review of utilizing SFT with families experiencing conflict makes the case that early intervention may reduce the rates of violence.
Family Relationships and Children's Sports: Therapeutic Considerations
Authors: Atwood Joan D. , Schaefer-Schiumo Kristin , Russo Ashlyn
Published: September 2022

According to the Hospital for Special Surgery, approximately 60 million children between the ages of 6 and 18 in the United States participate in organized sports activities every year. This involves approximately 75% of American families, with at least one child participating in an organized sports activity. The stated purposes of participation in organized sports activities are to assist children and teens in building skills, forming friendships, learning the value of teamwork, and possibly obtaining a scholarship to college. There are, however, related challenging issues. According to the Centers for Disease Control , the obesity rate for children and adolescents ages 2–19 living in the United States is 19.3%, affecting approximately 14.4 million children and adolescents. A sedentary lifestyle for children and teenagers contributes to this epidemic, while participation in sports is seen by many as protective. Challenges in participation, including increasing sports-related injuries, a 70% attrition rate by the time a child is 13 years of age, and programs overemphasizing winning are additional problems encountered in pre-teen and teen sports. The effect of pre-teen and teen participation in sports on family relationships is another potential source of stress and anxiety. This is the primary focus of this paper. The family relationships considered are the children, the parents, the couple, and the grandparents. Therapeutic suggestions and intervention considerations are then provided.

Published: September 2022

Well-differentiated/dedifferentiated liposarcoma (WDLPS/DDLPS) represent a significant number of sarcomas arising within the paratesticular region. DDLPS is notorious for a broad histologic spectrum, but epithelioid morphology is rare. Herein, we describe a unique case of paratesticular DDLPS with prominent epithelioid features and molecular confirmation. The patient is 71-year-old-male who presented with multiple paratesticular masses. Morphologic review of the resection specimen revealed a biphasic adipocytic neoplasm consistent with DDLPS. Additionally, epithelioid foci with acinar and nested architecture and focal keratin expression were noted. These areas raised the possibility of a secondary neoplasm including sex cord stromal tumor, germ cell tumor, and paraganglioma. However, MDM2 immunohistochemistry and FISH showed these areas to express MDM2 and exhibit MDM2 amplification, respectively, confirming that they represented a component of DDLPS. This case further highlights the morphologic diversity of DDLPS as well as the utility of MDM2 studies.
The Reliability and Predictive Validity of Sense of Coherence Scale for American Survivors of Gender-Based Violence
Authors: Zonp Zeynep , Saint Arnault Denise
Published: September 2022

This study investigated the reliability and predictive validity of the Sense of Coherence (SOC) scale for 299 American survivors of gender-based violence (GBV). First, confirmatory factor analysis examined the construct validity of the SOC-13. Then, relationships between SOC and clinical scales were examined. Confirmatory factor analysis supported the 3-factor solution, and Cronbach's alpha reliability values for comprehensibility, manageability, and meaningfulness subscales and total score of SOC-13 were: .62, .53, .65, and .81, respectively. Multiple regression revealed that age, posttraumatic growth, depression, and posttraumatic stress scores explained 53% of the variance of SOC scores. We interpret this to suggest that SOC is a protective factor in GBV, especially in younger women. Clinical implications are suggested.

Catheter-related complications in onco-hematologic children: A retrospective clinical study on 227 central venous access devices
Authors: Annetta Maria Giuseppina , Celentano Davide , Zumstein Lucrezia , Attinà Giorgio , Ruggiero Antonio , Conti Giorgio , Pittiruti Mauro
Published: September 2022

Background:

The use of central venous access devices (CVADs) is of paramount importance to safely deliver antiblastic and support therapies in children with cancer. Though, in pediatric patients, as much as in adults, CVADs are potentially associated with severe complications which may result in unscheduled interruption of therapy, hospitalization, increased morbidity/mortality, and increased cost of care.

Methods:

We have reviewed retrospectively our experience with CVADs in children with solid tumors and hematologic diseases, with the purpose of verifying if the adoption of well-defined insertion and maintenance bundles might be effective in reducing catheter-related complications, and in particular catheter-related thrombosis.

Results:

A total of 227 CVADs were analyzed: 175 peripherally inserted central catheters (PICCs), 50 centrally inserted central catheters (CICCs), and 2 femorally inserted central catheters. All CVADs were non-valved, non-cuffed power injectable polyurethane catheters; 81% were tunneled. Median dwelling time of CVADs was 172 days, for a total number of 39,044 catheter days. A very low incidence of both symptomatic catheter-related thrombosis (0.9%) and catheter-related blood stream infection (0.56 episodes per 1000 catheter days) was found. Unscheduled removal or guidewire replacement because of mechanic complications occurred in 15.7% of CVADs. There was no difference in terms of complications between PICCs and CICCs or between tunneled and non-tunneled catheters.

Conclusions:

Our experience with CVADs in oncologic and hematologic children suggests that catheter-related complications may be minimized by the adoption of appropriate insertion and maintenance bundles.
Land loss, confiscation, arability and colonisation: the experience of iwi in Aotearoa New Zealand
Authors: Thom Rowan Ropata Macgregor
Published: September 2022

This article examines the history of land alienation experienced by Māori in Aotearoa New Zealand across different iwi (tribes), exploring the connection between land loss and arability. The analysis uses geospatial data of Māori landholdings through time and explores the relationship that they have with Land Use Capability, a summary measure of the land’s economic potential. Two related factors are found to determine the variation of land alienation between iwi: (a) the arable profile of Māori land within the rohe (traditional land boundaries or territories) of an iwi and (b) the experience that iwi had with land confiscation. Iwi who held a large proportion of arable land and those that experienced land confiscations were more likely to experience land alienation. These findings reaffirm the historical narrative that Māori land suitable for arable use was targeted for alienation and illustrates the role of colonisation in perpetuating the historic trauma caused by these events.
Te Pā Auroa nā Te Awa Tupua: the new (but old) consciousness needed to implement Indigenous frameworks in non-Indigenous organisations
Authors: Cribb Miriama , Mika Jason Paul , Leberman Sarah
Published: September 2022

The Te Awa Tupua (Whanganui River Claims Settlement) Act 2017 formalised a new way to view, use and understand Te Awa Tupua—the Whanganui River. While giving legal personhood to a river is relatively recent, the paradigm shift towards a new consciousness of natural phenomena having physical and spiritual identities originates from Indigenous knowledge, values and practices. The framework that will implement this new change, Te Pā Auroa nā Te Awa Tupua, is values-based, appoints positions and governance groups, includes a whole-of-river strategy, is supported with funding and applies legal recognition to the Whanganui River and its intrinsic values. This article seeks to build a bridge of understanding to facilitate non-Indigenous engagement with implementing Te Pā Auroa nā Te Awa Tupua as an organising framework for human action and relations with human and nonhuman entities.
Numerical research of lubricant flow behaviors in rolling-slider bearing under the microscopic scale
Authors: Zhang Jingjun , Lu Liming , Huang Liang , Chen Bo , Ouyang Lu , Min Shilong
Published: September 2022

In order to reveal the fluid flow behaviors of rolling-slider bearing under the microscopic scale, a full-basin fluid-solid coupling model with different slider shapes is established by CFD and multiple mesh technology. The flow trajectory of fluid is monitored by a slip mesh model, and the dynamics performance is also compared. A reasonable model of rolling-slider bearing is derived. Moreover, this paper analyzes the influence of bearing speed, fluid viscosity, and fluid velocity on fluid behavior. The results show that there is a recirculation flow of fluid and vortex shedding in rolling-slider bearing during the process of lubrication. The distribution of maximum pressure on rolling body is in the orientation of bearing rotation. The fluid flow rate near inner ring is greater than that at outer ring. The established model is suitable for simulating the lubricant flow behaviors of rolling-slider bearings under different working conditions. It also provides a new method for designing the parameters of rolling-slider bearings and the function of working conditions.
“It's like having strong roots. We’re firmly planted”: Cultural identity development among Alaska Native University students
Authors: Buckingham Sara L. , Hutchinson Jacy R.
Published: September 2022

Cultural identity is associated with positive emotional and behavioral health. However, colonialism and its forces, past and present, have led to cultural loss in many Indigenous communities, contributing to health disparities. And yet, Indigenous peoples actively resist colonialism and work to maintain and revitalize their cultures around the globe. This study sought to understand how Alaska Native university students from diverse cultural backgrounds are presently developing and constructing their cultural identities. Transformational grounded theory methods were used to analyze seven focus groups with 20 Alaska Native university students from diverse cultural regions, now living in an urban center. Results revealed that identity was constructed as a series of nested and intersecting identities that centered on relations, place, and time across cultural groups. Cultural practices and values were often drawn upon to understand identity. Cultural identity was developed through storytelling, experiential learning, connection, personal exploration, and sharing with others. Relatives, particularly grandparents and Elders, and communities played a critical role in shaping cultural identity. The construction of cultural identity and its development diverged by setting of upbringing (rural, urban). Results have implications for the modification of structures and the development of cultural identity promotion programming to support Alaska Native young peoples’ identity development in an effort towards emotional and behavioral health.

Published: September 2022

An innovative shoe bolt connection for precast concrete (PC) structures that features resilience is proposed in this study. In this connection, a steel washer plate that could be easily replaced after an earthquake serves as the “fuse” element, and the bolt passing through the horizontal joints serves as the self-centring element. To validate the reliability of the proposed connection, quasi-static tests were conducted on two PC shear wall specimens. One specimen was designed with a conventional wall shoe bolt connection (S-1). The other specimen was designed with the proposed connection (S-2). The crack pattern, failure mode, hysteresis curve, skeleton curve, ductility and energy dissipation capacity of the specimens were studied. Furthermore, finite element (FE) analysis was conducted to reproduce the test and facilitate an in-depth understanding on the mechanism of the specimens. The test and analysis results indicated that S-1 exhibited brittle failure, while the failure of S-2 was governed by concrete crushing and fuse plate yielding and reflected a remarkable self-centring capacity; only minor shear slips of the horizontal joints occurred, even for the specimen S-1 with a smaller axial load ratio, indicating that the joints had enough shear resistance; the proposed three-dimensional FE model could predict the skeleton curve and the failure mode of the specimens with acceptable accuracy; for the specimen with proposed connection, the failure mode was significantly influenced by the thickness of the fuse plate.
Welcoming entanglements with ghosts: Re-turning, re-membering, and facing the incalculable in teacher education
Authors: Furman Cara E
Published: September 2022

Posthumanist and antiracist thinkers contend that justice, as articulated by Karen Barad, demands response-ability to ghosts of the past and those yet to come. Normative conceptions of the child do not account for these ghostly engagements. When such normative conceptions direct a teachers’ gaze, the child speaking with ghosts may feel they too are not welcome. Without kinship and support grappling with the challenging, even painful, topics that the ghosts raise, they may become discouraged from the larger project of taking response-ability for ghosts in pursuit of justice. In response, the author first repositions the child as rich in potential and a knower who engages with ghosts. Using “travel-hopping” as a methodology, she re-turns to an experience as a teacher who pursued a Master’s in Elementary Education as a conversation between her child self, ancestral ghosts, children she worked with, and ghosts those children spoke with. In sharing this experience, the author puts forth travel-hopping through experiences as a valuable method in teacher education. As teachers travel-hop, they can expand their sense of the “child” as capable and powerful in engagements with the more-than-human (broadly defined but focused on ancestral ghosts).
Being crime: Youth violence and criminal identities in Bahia, Brazil
Authors: Zoettl Peter Anton
Published: September 2022

In Brazil, a growing number of young citizens from the socioeconomic periphery embark on a career in crime, earning their living by armed robbery or selling drugs. Through the life stories and narratives of inmates of a juvenile prison in the state of Bahia, the article anatomizes what makes these young men take up and stick to a life in conflict with the law, despite the limited profits and substantial hardships involved. I argue that the experience of violence, both suffered and perpetrated, is central to the forging of the youths’ criminal identities, and their persistent failure to change their life trajectories.

Introduction

Transcarotid artery revascularization (TCAR) is a hybrid open and endovascular technique to treat carotid stenosis. The purpose of this study is to present a large cohort of patients who underwent TCAR at 2 high-volume TCAR health systems.

Methods

This study was a retrospective chart review of all instances of TCAR within the Memorial Hermann Health System and Indiana University Health, from December 2015-January 2022, using the ENROUTE Neuroprotection Device (Silk Road Medical, Sunnyvale, CA). We report patient demographics, intraoperative metrics, 30-day results and long-term results.

Results

In all, 750 patients underwent TCAR in the designated time period. Average patient age was 73 years, with 68% being male. Overall, 53.9% of patients had coronary artery disease, 45.4% had diabetes, and 36.9% were symptomatic. Technical success was achieved in 98.8% of patients with conversion to open endarterectomy in 1.1%. Average reverse flow time was 9.1 minutes with length of stay greater than 1 day 38%. Ipsilateral stroke rate within 30 days was 2.3% and long-term cumulative stroke rate was 3.0%. Death within 30 days occurred in 1.2% of patients and in 5.9% over long-term follow up. In all, 1% of patients required reintervention.

Conclusions

TCAR is a safe and effective treatment modality for carotid artery stenotic disease. Its outcomes are similar to historical results associated with carotid endarterectomy, long considered the gold standard.
Cerebral cortex Functional Networks of Transdermal Electrical Stimulation at Daling (PC7) Acupoint
Authors: Wang Haili , Yin Ning , Wang Aoxiang , Xu Guizhi
Published: September 2022

The cerebral cortex functional network of Electroencephalogram (EEG) signals during transcutaneous electrical acupoint stimulation (TEAS) on 21 healthy subjects was constructed by using three modules: standard low-resolution brain electromagnetic tomography (sLORETA), phase-locking value ( PLV), and complex network. We investigated the brain functional network triggered by PC7 stimulation by comparing with resting state and non-acupoint stimulation. The results showed that the PC7 stimulation mainly activated frontal lobe and temporal lobe including prefrontal cortex (BA10), insular lobe (BA13), temporal gyrus (BA22), anterior cingulate cortex (BA32), temporal pole (BA38), dorsolateral prefrontal cortex (BA46), and inferior frontal cortex (BA47), which are all closely linked to cognition, spirit, and emotion in brain. Furthermore, the degrees of node in frontal, temporal, and whole brain are increased significantly or extreme significantly with p < 0.05, p < 0.05, and p < 0.01, respectively; clustering coefficient in frontal, temporal, and whole brain are all statistically significant ( p < 0.05). The information transmission efficiency of cerebral cortex has been greatly improved. During PC7 stimulation, the topological changes in the activation of cerebral regions and cortical functional networks are consistent with the therapeutic effect, which may provide theoretical support for acupoint stimulation to regulate nerve function.

Objective

To assess clinical characteristics and outcomes of women who underwent concurrent valve replacement with caesarean section for severe rheumatic mitral valve disease with refractory heart failure.

Methods

All women admitted to a single centre from 2011 to 2020 with severe rheumatic mitral valve disease, having recurrent episodes of pulmonary edema on optimal medical therapy and contraindication to percutaneous balloon mitral valvotomy, who underwent concurrent valve replacement (for native valve disease) along with caesarean section, were included.

Results

Among 1300 pregnancies with rheumatic heart disease, six underwent the concurrent procedure. All had replacement of mitral valve except one who had both aortic and mitral valve replacements, between 33 and 39 weeks of gestation. There were no maternal deaths, and there was one neonatal loss from late-onset sepsis.

Conclusion

Pregnant women with severe rheumatic mitral valve disease with refractory heart failure, unsuitable for minimal access interventions, can be considered for a concurrent valve replacement with caesarean section.
