The entrepreneurial imaginary: The hyper-real case of the Zombiepreneur
Authors: Newbery Robert , Jinman Andrew
Published: July 2021

Contemporary representations of entrepreneurship only reflect the past and present, not the utopian or dystopian futures that entrepreneurial behaviours may create. Given calls for alternative narratives of entrepreneurship that challenge the orthodoxy, there is a need to critique the multiple simultaneous representations of entrepreneurship and their potential impact on our future. Using Baudrillard’s concept of simulacra, this paper proposes a new epistemological way to interrogate future entrepreneurial reality through a radical hyper-real frame and an empirical deviation from the norm. The paper introduces and critiques representations that contribute an entrepreneurial imaginary based on contemporary discourse. Through viewing and coding for entrepreneurial behaviours observed in the top-30 Zombie movies, a deviant simulacrum that is far from our field is constructed. This is used to generate a new empirically derived taxonomy that challenges existing entrepreneurial representations and suggests the impossibility of a single entrepreneurial reality. Through this deconstruction, we highlight how entrepreneurial behaviours take on alternative meaning when explored through other realities. By comparing the Zombie genre as simulacra with extant entrepreneurial simulacra, we critically challenge our entrepreneurial system of meaning, providing a perspective where entrepreneurial behaviour may lead to different outcomes depending on the reality pursued.
Ideals and realities in the involvement of Filipino immigrant mothers in their children’s education in South Korea
Authors: Kim Younghan
Published: July 2021

Parental involvement in children’s education plays a crucial role in a child’s life. However, meaningful parental involvement is often a difficult task for immigrant parents because of multiple challenges such as limited resources and information, language barriers, and cultural differences. This article presents findings from qualitative research interviews on the involvement of Filipino immigrant mothers in their children’s education in South Korea. The results indicate that the immigrant parents take their children’s education seriously. They want to raise their children to be happy and successful, knowing that performing well in school is the key to a successful life as an adult, especially in a nation with a fervor for education. Like other parents, they are willing to devote themselves to their children above all else. Compared with previous studies, not many barriers to involvement were revealed in this study. Only two, language barriers and financial concerns, were expressed by all participants as obstacles to involvement in their children’s education. Yet, the true, hidden barrier is how the immigrant parents view their Korean proficiency. They over-emphasize the language barrier, which causes them to avoid conversations with others.
The Sexual Fantasies of Childhood Sexual Abuse Survivors: A Rapid Review
Authors: Gewirtz-Meydan Ateret , Opuda Eugenia
Published: July 2021

Although the association between childhood sexual abuse (CSA) and various aspects of sexual difficulties is well established, little is known about the association between CSA and adult sexual fantasies. The current rapid review searched for studies that reported on CSA and sexual fantasies through PubMed, PsycInfo, and Violence & Abuse Abstracts databases. Included in the review were empirical studies involving a population of adults who experienced CSA before the age of 18 and which reported on survivors’ sexual fantasies. The impact of CSA on adult sexual fantasies was found across three main dimensions: prevalence of sexual fantasies, content, and appraisal of the fantasies. Overall, 13 studies that addressed the sexual fantasies of survivors of CSA were identified. This review found an association between CSA and adult sexual fantasies, indicating that survivors of CSA are more likely to report: unrestricted sexual fantasies, more atypical sexual fantasies, more sexual fantasies that involve force, and more fantasies that include elements of sadomasochism, submissiveness, and dominance. Survivors of CSA also begin having sexual fantasies at a significantly earlier age and report their sexual fantasies as being significantly more intrusive than do nonabused subjects. When treating CSA survivors, therapists should acknowledge that a history of CSA can impact the survivors’ sexual fantasies. Further studies with adult survivors of CSA are needed to determine how these sexual fantasies develop subsequent to the abuse, how they are perceived by survivors, and what their effect is on survivors’ and their partners’ sexual health, function, and satisfaction.

Published: July 2021

Given how smart phones, internet services, and social media have shown great potential for assisting smoking cessation, we constructed a Facebook chat application based on our previous work with SMS texting services. This report summarizes findings from 2,364 Spanish-speaking young adults recruited through Facebook advertising in South Texas during the 2020 New Year holiday season. Among these service users, 926 (39%) were ready to make a quit attempt, and 26 (3.1%) of those users reported that they were tobacco free 1 month later. There were no responses to a chat question survey 72 days after the dates selected for quitting. Although more research with longer follow up is needed, these findings show that social media chat applications may be helpful for at least prompting quit attempts and short-term cessation among young adult Spanish-speaking smokers. There is no evidence of an impact on long-term cessation, and more research is clearly needed.
A Natural Experiment: Results of Community-Designed Park Improvements on Park Use and Physical Activity
Authors: Kelly Cheryl , Clennin Morgan , Hughey Morgan
Published: July 2021

The objective of this study was to assess if built environment changes to two suburban parks that involved extensive community engagement and physical activity programming increased park use and physical activity. This study employed a natural experiment evaluation design where community engagement informed the redesign of two neighborhood parks. Community engagement in the redesign of the parks was tracked as was the diversity of the partners on the steering committee and participation by community members in the process. Before and after park improvements, data were collected using the System for Observing Play and Recreation in Communities (SOPARC) instrument to measure change in use and activity level in each park. Park use increased at both parks, but physical activity levels did not significantly improve. The number of park visitors observed increased by 53% and 50%, respectively. Both parks had increased usage during evening hours when the family programming was the greatest. This study has several implications for policy and practice. First, this study suggests that community engagement can play a role in redesigning a park and likely leads to increased awareness and use of neighborhood parks. Second, while park use increased, simply adding new features to a park may not immediately increase physical activity. Additional efforts need to be made to activate the park and increase physical activity. Third, practitioners should not discount the value of building park awareness that increases park use as it may be a first step to increasing physical activity.
Mainstream Media Recirculation of Trust-Reducing Social Media Messages
Authors: Christensen Devin J. , Lovett John , Curiel John A.
Published: July 2021

Citizens need to trust in the integrity of news reporting for the free press to fulfill its role as a democratic institution that enables citizens to hold representatives accountable. Growing research has shown that increased use of social media erodes trust in legacy news. However, trust-reducing social media messages are not contained to social media platforms; they are widely recirculated by the mainstream media. We argue that mainstream media corporations select social media messages to recirculate precisely because of their trust-reducing features in order to respond to short-term competitive market incentives. We turn to Donald Trump’s Twitter posts as examples of trust-reducing messages and show that the media cites more trust-reducing messages more quickly and more frequently than less trust-reducing messages. These findings implicate mainstream media corporations alongside social media platforms in the systematic and ongoing degradation of trust in legacy news reporting.
Functional Communication Training and Most-To-Least Prompting as Treatments for Problem Behavior
Authors: Axe Judah B. , Murphy Corinne M. , Heward William L.
Published: July 2021

Functional communication training (FCT) is a treatment for problem behavior in which the learner is taught a communicative behavior that fulfills the same function as the problem behavior. Although effective, when FCT is used to request breaks from work, limitations include increased time spent in breaks and reduced task-related responding. An alternative treatment is most-to-least prompting (MTL) of a task in which a therapist provides the most helpful prompts for task-related responding (e.g., physical guidance) and gradually reduces the amount of help (e.g., visual prompt and then verbal) until the learner responds independently. We evaluated FCT and MTL in a multiple treatments design with an 11-year-old girl with severe developmental disabilities. Both treatments reduced problem behavior from baseline levels, and academic responding was greater during MTL than during FCT. MTL is an errorless teaching approach conceptualized as an abolishing operation that reduces the aversiveness of a task and makes escape less valuable.
Adipose-derived stem cells in ovarian cancer progression, metastasis, and chemoresistance
Authors: Zhang Wenjing , Torres-Rojas Carolina , Yue Junming , Zhu Bing-Mei
Published: July 2021

Ovarian cancer is the deadliest gynecological malignancy due to its symptomless early stage, metastasis, and high recurrence rate. The tumor microenvironment contributes to the ovarian cancer progression, metastasis, and chemoresistance. Adipose-derived stem cell in the tumor microenvironment of ovarian cancer, as a key player, interacts with ovarian cancer cells to form the cancer-associated fibroblasts and cancer-associated adipocytes, and secretes soluble factors to activate tumor cell signaling, which can promote ovarian cancer metastasis and chemoresistance. We summarize in this review the recent progress in the studies of interactions between adipose-derived stem cell and ovarian cancer, thus, to provide some insight for ovarian cancer therapy through targeting adipose-derived stem cell.

Published: July 2021

Physical health diseases caused by wrong sitting postures are becoming increasingly serious and widespread, especially for sedentary students and workers. Existing video-based approaches and sensor-based approaches can achieve high accuracy, while they have limitations like breaching privacy and relying on specific sensor devices. In this work, we propose Sitsen, a non-contact wireless-based sitting posture recognition system, just using radio frequency signals alone, which neither compromises the privacy nor requires using various specific sensors. We demonstrate that Sitsen can successfully recognize five habitual sitting postures with just one lightweight and low-cost radio frequency identification tag. The intuition is that different postures induce different phase variations. Due to the received phase readings are corrupted by the environmental noise and hardware imperfection, we employ series of signal processing schemes to obtain clean phase readings. Using the sliding window approach to extract effective features of the measured phase sequences and employing an appropriate machine learning algorithm, Sitsen can achieve robust and high performance. Extensive experiments are conducted in an office with 10 volunteers. The result shows that our system can recognize different sitting postures with an average accuracy of 97.02%.
Better Game Worlds by Design: The GAS Framework for Designing and Analyzing Games Based on Socio-Ecological Systems Thinking, Demonstrated on Nusfjord (2017)
Authors: Weines Jørn , Borit Melania
Published: July 2021

The goal of this article is to propose Game World Design and Analysis for Socio-Ecological Systems (GAS), a framework for the design and analysis of game worlds through socio-ecological systems lenses. Game World Design and Analysis for Socio-Ecological Systems invites designers to a structured reflection of their choices regarding game world correspondence with a real or fictional reference system (assessed through accuracy, comprehensiveness, and balance) and game world consistency. The framework spells out the main elements to be included in the game world for that to be a credible socio-ecological system. The GAS framework is demonstrated on Nusfjord (2017) as an exemplar of natural resource management–themed analog game. The framework is built using an interdisciplinary approach to game studies, history, media and literary studies, and natural resource management research. The application of the framework has the potential of making the design and analysis of game worlds more relevant to the sustainability discourse of the 21st Century.
Preoperative Guidance With Weight-Bearing Computed Tomography and Patient-Specific Instrumentation in Foot and Ankle Surgery
Authors: Zeitlin Jacob , Henry Jensen , Ellis Scott
Published: July 2021

The use of preoperative and intraoperative guidance in foot and ankle surgery has grown substantially in recent years. Weight-bearing computed tomography (WBCT) and patient-specific instrumentation (PSI) are used in total ankle arthroplasty (TAA) to achieve precise bone cutting and implant positioning, and intraoperative 3-dimensional (3D) imaging has been used to reduce complications and improve clinical outcomes in other foot and ankle surgical procedures. This narrative review of the literature focuses on the evidence supporting the use of WBCT and PSI in TAA and looks at other promising technologies used to guide foot and ankle surgery.
COVID-19 and MENtal Health: Addressing Men’s Mental Health Needs in the Digital World
Authors: Ellison Jennifer M. , Semlow Andrea R. , Jaeger Emily C. , Griffth Derek M.
Published: July 2021

The COVID-19 pandemic continues to be a source of stress and have important mental health implications for all persons but may have unique implications for men. In addition to the risk of contracting and dying from COVID-19, the rising COVID-19 death toll, ongoing economic uncertainty, loneliness from social distancing, and other changes to our lifestyles make up the perfect recipe for a decline in mental health. In June 2020, men reported slightly lower rates of anxiety than women, but had higher rates of depressive symptoms and suicidal ideation. As of September 2020, men sought mental health care at a higher rate than women for family and relationships, with year-over-year visits up 5.5 times and total virtual mental health care visits monthly growth in 2020 was up 79% since January. Because men are not a homogeneous group, it is important to implement strategies for groups of men that may have particularly unique needs. In this paper, we discuss considerations for intervening in men’s mental health during and in response to the COVID-19 pandemic, including current technology-based cyberpsychology options.
Prognostics of fractional degradation processes with state-dependent delay
Authors: Xi Xiaopeng , Zhou Donghua
Published: July 2021

In modern industrial processes, the remaining useful life (RUL) of core manufacturing equipments is regarded as an important indicator for assessing the continuous serving ability by considering safety and reliability. Accurate RUL predictions contribute to saving maintenance costs, and can be applied to the life extension technologies. Being subjected to complicated noise environments, the fractional characteristic usually exists in the stochastic heterogeneous diffusions. Traditional methods mostly utilize the fractional Brownian motion (FBM) to describe a simple class of memory effect in the time domain, but lose sight of potential time-varying state-dependencies from historical information. In view of uncertain lagging levels, the state-dependent delay (SDD) is introduced to construct a novel nonlinear fractional degradation model in this paper. Based on a specific discretization scheme, the unknown parameters are estimated by optimizing an approximate log-likelihood function. The RUL distribution is then derived under a Markovian statistical transformation. Finally, a case study on certain hearth wall degradation processes is provided to validate the proposed prognostic method in production practice.
Changes of Walking Activity During the First Cycle Phases of COVID-19 Pandemic: A Case Study of Seoul, Korea
Authors: Park Youngjun , Chung Haekwon , Park Sohyun
Published: July 2021

Aim:

This study explores the changes in regular walking activities during the phases of the pandemic.

Background:

With the spread of COVID-19 transmission, people are refraining from going out, reducing their physical activity. In South Korea, COVID-19 broke out in the 4th week of 2020 and experienced the first cycle phases of the pandemic, such as outbreak, widespread, and decline. In response to the pandemic, the government encouraged voluntary participation in social distancing campaigns, and people reduced their outside activities.

Methods:

This article examines the decrease and increase of the Prevalence of Regular Walking (≥30 min of moderate walking a day, on ≥5 days a week) by the COVID-19 phases. This study is based on weekly walking data for 15 weeks in 2020, via the smartphone healthcare app, which is managed by 25 public health offices of the Seoul government.

Results:

According to the findings, the level of prevalence of regular walking (PRW) has a significant difference before and after the outbreak, and every interval of the four-stage COVID-19 phases, that is, pre-pandemic, initiation, acceleration, and deceleration. The level of PRW sharply decreased during initiation and acceleration intervals. In the deceleration interval of COVID-19, the PRW kept increasing, but it has not yet reached the same level as the previous year when the COVID-19 did not exist.

Conclusions:

As a preliminary study, this study explains empirically how COVID-19 changed PRW in Seoul. It would be helpful to enhance our understanding of the changes in physical inactivity in the pandemic period.

Regulation of the Expression of SARS-CoV-2 Receptor Angiotensin-Converting Enzyme 2 in Nasal Mucosa
Authors: Takabayashi Tetsuji , Yoshida Kanako , Imoto Yoshimasa , Schleimer Robert P. , Fujieda Shigeharu
Published: July 2021

Background

Coronavirus disease 2019 (COVID-19) has caused a global pandemic. Higher expression of the virus receptor angiotensin-converting enzyme 2 (ACE2) in the nasal mucosa may be associated with high transmissibility and asymptomatic infection. In COVID-19, the elucidation of the determinants of ACE2 expression at nasal tissue level is crucial. The development of strategies to downregulate ACE2 expression in nasal epithelial cells might reduce transmission and be useful as a novel therapeutic approach.

Objective

To verify ACE2 expression in the nasal mucosa of patients with seasonal allergic rhinitis induced by Japanese cedar pollen (SAR-JCP) and chronic rhinosinusitis with nasal polyp (CRSwNP) and to examine the effects of short-chain fatty acids (SCFAs) on ACE2 expression in airway epithelial cells.

Methods

We assessed ACE2 expression in the nasal mucosa of control subjects, patients with SAR-JCP, and those with CRSwNP using real-time polymerase chain reaction. We also quantified ACE2 gene expression in cultured airway epithelial cells.

Results

Although ACE2 expression was greatly increased in a few patients with SAR-JCP during the Japanese cedar pollen season, mean levels were not significantly increased. ACE2 mRNA expression was significantly decreased in nasal polyp tissue from patients with chronic rhinosinusitis compared with the expression in that from control subjects. SCFAs generated by gastrointestinal microbiota significantly reduced resting ACE2 expression in cultured airway epithelial cells. SCFAs also significantly suppressed the dsRNA-dependent upregulation of ACE2 expression in airway epithelial cells.

Conclusion

Inflammatory endotype affects ACE2 expression in the nasal mucosa and influences susceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In particular, type 2 inflammation could downregulate ACE2 expression in the nasal mucosa and reduces susceptibility to SARS-CoV-2 in patients with CRSwNP. Although in vivo experiments are required, administration of SCFAs to the nasal cavity might be worthy of consideration as a preventative or therapeutic strategy for the early-stage COVID-19.
Nursing preceptorship, a supportive and reflective approach for promoting a healthy working environment: a multi-methods design
Authors: Jochim Verena , Rosengren Kristina
Published: July 2021

Shortage of nurses negatively influences the working environment in hospitals, by placing extra burden on newly graduated nurses. Thus, it is important to improve the knowledge and skills of nurses to increase their confidence levels. Experienced nurses serve as role models for junior nurses. This study aimed to describe and analyze a project with a nursing preceptorship in an internal medicine ward in the eastern region of Sweden. Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0) were used in the multi-method approach. Quality indicators, staff turnover, short-term absence, and annual survey were analyzed using descriptive statistics. Moreover, two focus group interviews were analyzed using qualitative content analysis. The results showed marginal improvements due to quality indicators and working environment, and decreased staff turnover and short-term absenteeism. Two factors, ‘supportive working environment’ and ‘improvement in nursing’, were identified. The study concluded that selection of nurse preceptors with expertise and interest in supportive and reflective approaches is significant for promoting a healthy working environment. Moreover, interventions such as nursing preceptorship facilitate implementation (<one year) and evaluation using a multi-method design to describe, explain, and understand the possible considerations and consequences of quality improvement in healthcare.
The Dynamics of Business Model Innovation for Technology Entrepreneurship: A Systematic Review and Future Avenue
Authors: Wang Run , Chebo Abdella Kosa
Published: July 2021

Technology entrepreneurship involves creating sustainable value through capitalization and commercialization of innovative new technology, accelerates the growth of firms, and helps in promoting the sustainability of the economy. However, the literature on the business model innovation (BMI) for technology entrepreneurship has no clarity yet. Therefore, this article aims to build a business model innovation for technology entrepreneurship (BMIfTE) toward economic sustainability. To meet this aim, various publications on the subject matter have been reviewed and synthesized and I compared the logic and arguments of various scholars to draw conclusions and develop BMIfTE. The article structures the BMI for technology entrepreneurship as obtained through experimentation, generating, renewing, designing, changing, and implementation, backed by inputs such as value migration, opportunity and risk assessment, dynamic capability, stakeholders networking, firms’ strategies, and institutional ontology that contribute to sustainable economic development. In this sense, the BMI improves the current delivery system by creating a new offering system, which leads to a reconfiguration of the model by integrating with the technological ecosystem’s capabilities in creating and exploiting new business opportunities.

Published: July 2021

Psychotic expression is influenced by unique contexts, including the individual’s culture. The majority of research on psychotic experiences is quantitative and from Western, democratic societies. This article explores the explanatory models used by Saudis to describe psychotic experiences (i.e., hallucinations and delusions). Using open-ended responses to a structured psychosis screener embedded within a comprehensive mental health survey instrument, we conducted thematic analysis on data representing the psychotic experiences of 59 individuals. We found that Saudis report religious (e.g., Jinns) and cultural (e.g., modest clothing) frameworks alongside biological, psychological, and social mechanisms which potentially trigger an alternative reality for the affected individual. Our findings suggest it may be helpful for health care professionals to consider individual differences and work with religious leaders (e.g., Shaykhs) to prevent misdiagnosis and mistreatment. In-depth qualitative studies are needed to examine trajectories of psychotic symptomatology among Saudis and the specific language used to describe such occurrences.
A Whole Other Story: Interpreting Narrative Medicine
Authors: Salana Kristen , Maty Shauna , Hage Robert
Published: July 2021

The practice of conventional medicine is rooted in the ability of a patient to effectively communicate with their physician, and for the physician to comprehend the patient’s story and perceive it through the lens of evidence-based practice. In reality, the differences in environmental backgrounds hinders this exchange of information and prevents a shared understanding and strategy. Narrative medicine provides a framework in which this divide can be bridged by encouraging the clinician to develop an appreciation of cultural nuances that drive a patient’s decision making. The importance of this practice is highlighted with four stories in which the only path to competent patient management was through the utilization of narrative medicine.

Published: July 2021

Ethiopia has a high neonatal mortality rate in spite of dearth of study. Therefore we aimed to assess magnitude and associated factors of neonatal mortality among neonates admitted to neonatal intensive care units of Wollega University Referral Hospital. Accordingly, a facility based cross-sectional study was conducted on 289 by reviewing medical records of neonates admitted to neonatal intensive care unit. The collected data were entered in to Epi data version 3.1 and Stata version 14 used for analysis. Variables with P-value  < 0.25 at with 95% confidence interval in binary logistic regression analysis were taken to the multiple logistic regression analysis. Finally, variables with Likewise, variable with P-value < 0.05 at 95% confidence interval in multiple logistic regression analysis were considered as statistically significant. Among 289 neonates admitted to neonatal intensive care unit, 53 (18.34 %) were died. Majority 42(79.25%) of those deaths occurred at ≤ 7 days of birth. Preterm [AOR 4.15, 95% CI (1.67-10.33)], neonates faced birth asphyxia [AOR 3.26, 95% CI (1.33-7.98)], neonates who developed sepsis [AOR 2.29 95% CI (1.01-5.20)] and neonates encountered with jaundice [(AOR 11.08, 95% CI (1.03-119.59)] were more at risk to die. In general, the magnitude of neonatal mortality among neonates admitted to neonatal intensive care unit was high. Gestational age (maturity of new born), birth asphyxia, neonatal sepsis and neonatal jaundice were predictors of neonatal mortality. Neonates admitted to neonatal intensive care unit with sepsis, jaundice, and birth asphyxia demand special attention to reduce neonatal mortality.
Being Black in 21st-Century America: Struggle, Challenges and Possibilities
Authors: Narnolia Nitesh , Kumar Naresh
Published: July 2021

This study attempts to define struggle and challenges black population of USA has been facing since ages and still facing in this 21st century when whole world is heading towards globalisation and post-modernism. As it has been reflected in the history of the nation, racial segregation has always been a part of national society and culture. This racial segregation has led the black population of USA to raise their voice for civil rights as well as equal opportunities in every field. These struggles and challenges before blacks to lead a dignified life have opened the future possibilities where both black and white youth’s understanding of race relations is required. The white youth of America is equally responsible for providing equal space to blacks in American society, culture and politics. Hence, the present study attempts to look at the history of race relations and relevance of race and race relations in the 21st-century USA, with special reference to the current issue of George Floyd in order to explain how status of blacks in the 21st-century USA is affected by this history and attitude of the State.
Applying Synthetic Control Method to Estimate the Impact of the Lava Jato Operation on the Worldwide Governance Indicators in Brazil
Authors: Alencar Eduardo Carvalho Nepomuceno , Jackson-Green Bryant
Published: July 2021

In 2014, the most prominent anti-corruption investigation in Latin America called Lava Jato, exposed a Brazilian corruption scheme with reverberations in 61 countries, resulting in legal judgments for nearly 5 billion USD in reimbursements thus far. This article applies the synthetic control method on data from 135 countries (2002–2018) to test the hypothesis that Lava Jato impacts the Worldwide Governance Indicators in Brazil. The findings reveal that Lava Jato negatively affects control of corruption, the rule of law, and regulatory quality. There are signs of possible improvement in at least the corruption and the rule of law measures. This paper brings value to the criminological body of literature, notably lacking in the Global South.
Remembering Materiality: A Material–Relational Approach to Organizational Memory
Authors: Eisenman Micki , Frenkel Michal
Published: July 2021

In this paper, we develop a material–relational approach to understanding organizational memory. We focus on the inherent materiality of mnemonic devices—material artifacts that anchor shared memories of the past. Mnemonic devices work to constitute social groups of organizational stakeholders bound together by mutual affinities to these devices, known as mnemonic communities. While we know that the materiality of mnemonic devices represents information about the past that is interpreted by members of the mnemonic community as a narrative that is important in the present, our approach focuses on how engagement with the material aspects of mnemonic devices can create relationships of affinity among people remembering together. To develop our conceptualization, we first apply insights from the literature on materiality and its emphasis on how materiality is the basis for non-verbal and relational communication. From this, we theorize four material attributes that affect how mnemonic devices constitute relational connections that create embodied, cartographic, and temporal boundaries for organizational mnemonic communities. We then conceptualize how these distinct material attributes accumulate, intersect, and interact with each other and with the narrative representations of mnemonic devices and how in turn these interactions may bind stakeholders together. By emphasizing the material–relational aspect of mnemonic devices, our paper theorizes a broader and potentially more powerful set of affinities between stakeholders and organizations and, on this basis, enhances extant research by articulating different paths to the emergence of mnemonic communities.
Seismic risk assessment for the CEUS nuclear power plant fleet based on the NGA-East ground motion model
Authors: Talaat Mohamed M , Graf Timothy J , Anup Abhinav , Hardy Gregory S , Richards John M
Published: July 2021

Knowledge of seismic hazard at engineered facilities evolves with the growth in related technical fields. This presents challenges to stability and decision-making concerning safety that require effective assessment tools. Updated mean hazard estimates were developed at nuclear power plant (NPP) sites in Central and Eastern United States (CEUS) using the Next Generation Attenuation (NGA)-East ground motion model (GMM) and the latest available site amplification data. These estimates indicated that seismic hazard increases at several CEUS NPP sites, especially for spectral frequencies below 5 Hz. To assess the safety implications, updated mean seismic core damage frequency (SCDF) estimates were developed for the CEUS NPP fleet using the updated mean hazard estimates and updated plant-level fragilities (PLFs). The PLFs were developed from plant-specific information compiled by the U.S. Nuclear Regulatory Commission (USNRC) and recent seismic probabilistic risk assessments (SPRAs) completed by some NPPs. The SCDF quantification followed a method defined by the USNRC to combine risk contributions from different spectral frequencies. While not intended to provide a precise quantification of risk, such as that provided by a full SPRA, when the results are compared against other estimates using the same approach, this process provides valuable insight into the overall change in risk as the understanding of hazard changes. The assessment indicated no significant change in estimated risk for the majority of the CEUS fleet compared to the 2010 USNRC estimates—about 90% of the fleet risk distribution was lower, equal, or slightly higher. A few NPPs had SCDF estimates significantly larger than the 2010 estimates. The SCDF increases at these few NPPs have larger contributions from updated PLFs than updated hazard estimates. The majority of these NPPs have recently completed detailed SPRAs and have tools to develop more accurate estimates of the updated risk than can be achieved in this fleet-level study.
Small Town Transition Services Model: Postsecondary Planning for Students With Autism Spectrum Disorder
Authors: Eastman Karen , Zahn Gail , Ahnupkana Wendy , Havumaki Bryson
Published: July 2021

Graduating from high school and moving to the next phase of life can be difficult for any student but is particularly so for those with autism spectrum disorder (ASD). Social and communication difficulties, sensory concerns, and narrow interests can negatively affect these students’ opportunity for postsecondary education and employment. Preparing students with ASD for post-school success may be especially challenging in rural schools, due to limited opportunities and resources. This article describes a rural high school transition services program designed to support students with ASD and other disabilities in becoming gainfully employed after high school or accessing post-secondary education. The program, designed by a student’s transition team starting in Grade 9, is based on recommendations from the literature and includes inclusion and co-teaching, work skills classes, collaboration with outside agencies, and the development of a student portfolio.
“Trends Come and Go”: Early Childhood Rural Special Education Teachers’ Use of Reported Practices During Mathematics Instruction
Authors: Peltier Corey , Peltier Tiffany K. , Hott Brittany L. , Heuer Andrew , Werthen Taylor
Published: July 2021

Data suggest students are not meeting grade-level expectations in mathematics. If high-quality instruction is not provided, the inequitable outcomes observed in schools will be maintained. The goal of this study was to identify the frequency in which rural special education teachers (SETs) serving students in prekindergarten through third grade self-report using practices during mathematics instruction. A secondary focus was to investigate whether rural SETs differed in their reported use of practices compared with (a) suburban and urban SETs and (b) rural general education teachers. Data from 901 teachers serving students in prekindergarten through third grade were retained. Of this sample, 150 teachers identified as SETs in rural ( n = 55), suburban ( n = 50), and urban ( n = 45) schools.

Background

Previous studies have validated the capability of SYNTAX score (SS) and clinical SYNTAX score (CSS) in the prediction of clinical outcomes in patients who have undergone PCI; however, studies on comparison of these two scoring systems in Chinese population have been sparse.

Methods

To study the ability of SS and CSS in prediction of clinical outcomes of Chinese patients underwent percutaneous coronary intervention (PCI). We retrospectively calculated SS and CSS for 547 Chinese patients from a single center who underwent PCI. Patients were stratified into tertiles according to their SS and CSS. We compared the 2-year clinical outcomes in these patients stratified separately by SS and CSS tertiles.

Results

The incidence of major adverse cardiac and cerebro-vascular events (MACCE) was the highest in patients with SSHIGH(13.5%), comparing to 6.8% in SSMEDand 0% in SSLOW(p < 0.0001). The Cox multivariable analysis showed that the SS and CSS were both strong independent predictors for MACCE [1.100 (1.069–1.133), 1.017 (1.010–1.025), bothp < 0.0001]. The receiver operating characteristic (ROC) curves showed the areas-under-the-curves for all-cause death by CSS was slightly larger comparing to SS but not significantly (AUC SS, 0.64; AUC CSS, 0.71;p = 0.23).

Conclusion

We concluded that both the SS and CSS were capable of risk stratification of clinical outcomes in all-comers population as well as in low and moderate risk Chinese patients undergoing PCI with CSS showing slightly better advantage.

Background

The reproduction number is one of the most crucial parameters in determining disease dynamics, providing a summary measure of the transmission potential. However, estimating this value is particularly challenging owing to the characteristics of epidemic data, including non-reproducibility and incompleteness.

Methods

In this study, we propose mathematical models with different population structures; each of these models can produce data on the number of cases of the influenza A(H1N1)pdm09 epidemic in South Korea. These structured models incorporating the heterogeneity of age and region are used to estimate the reproduction numbers at various terminal times. Subsequently, the age- and region-specific reproduction numbers are also computed to analyze the differences illustrated in the incidence data.

Results

Incorporation of the age-structure or region-structure allows for robust estimation of parameters, while the basic SIR model provides estimated values beyond the reasonable range with severe fluctuation. The estimated duration of infectious period using age-structured model is around 3.8 and the reproduction number was estimated to be 1.6. The estimated duration of infectious period using region-structured model is around 2.1 and the reproduction number was estimated to be 1.4. The estimated age- and region-specific reproduction numbers are consistent with cumulative incidence for corresponding groups.

Conclusions

Numerical results reveal that the introduction of heterogeneity into the population to represent the general characteristics of dynamics is essential for the robust estimation of parameters.

Background

In neurosurgery, it is important to use local hemostatic agents. We have explored a more powerful method of hemostasis by the combination of commercially available hemostatic agents with fibrin glue in the hopes of synergistic effects.

Method

A bleeding model was constructed by puncturing the rabbit posterior vena cava with a needle. After applying the sample to the bleeding point, compression was performed for 10 s. If temporary hemostasis was achieved after pressure release, a 30 s wash was performed to confirm that ultimate hemostasis was achieved. Up to three hemostasis attempts were performed on the same bleeding point until hemostasis was achieved, and the number of attempts required for hemostasis was counted. If hemostasis was not achieved after three attempts, it was counted as four times. Four groups were evaluated: (1) gelatin sponge alone, (2) gelatin sponge + fibrin glue, (3) oxidized cellulose alone, and (4) oxidized cellulose + fibrin glue; each group was tested 16 times.

Results

The median value (range minimum value–maximum value) of the number of hemostatic attempts in Group 1 to Group 4 was 3 (1–4), 1 (1–1), 4 (4–4), and 4 (2–4). In Group 2, there were two test exclusions owing to deviations of the test procedure.

Conclusions

The compatibility of gelatin sponge and fibrin glue was very good, with a very strong and rapid hemostatic effect compared to other methods, showed its usefulness. This combination method may be effective for a variety of venous hemorrhages in neurosurgery.
Utilization of preconception care and its impacts on health behavior changes among expectant couples in Shanghai, China

Published: July 2021

Background

Preconception care is an opportunity for detecting potential health risks in future parents and providing health behavior education to reduce morbidity and mortality for women and their offspring. Preconception care has been established in maternal and child health hospitals in Shanghai, China, which consists of health checkups, health education and counseling. This study investigated factors associated with the utilization of preconception care, and the role of preconception care on health behavior changes before conception among pregnant women and their partners.

Methods

A cross-sectional study was conducted among pregnant women at three maternal and child health hospitals in Shanghai. The participants were invited to complete a self-administered questionnaire on the utilization of preconception care and health behavioral changes before conception.

Results

Of the 948 recruited pregnant women, less than half (42.2%) reported that they had utilized preconception care before the current pregnancy. Unplanned pregnancy, unawareness of preconception care and already having a general physical examination were the main reasons for not attending preconception care. The two main sources of information about preconception care were local community workers and health professionals. Younger women and the multipara were less likely to utilize preconception care. Women who utilized preconception care were more likely to take folic acid supplements before conception [Adjusted Odds Ration (aOR) 3.27, 95% Confidence Interval (CI) 2.45–4.36, P < 0.0001]. The partners of pregnant women who had attended preconception care services were more likely to stop smoking [aOR 2.76, 95%CI 1.48–5.17, P = 0.002] and to stop drinking [aOR 2.13, 95%CI 1.03–4.39, P = 0.041] before conception.

Conclusions

Utilization of preconception care was demonstrated to be positively associated with preconception health behavior changes such as women taking folic acid supplements before pregnancy, their male partner stopping smoking and drinking before conception. Future studies are needed to explore barriers to utilizing preconception care services and understand the quality of the services. Strategies of promoting preconception care to expectant couples, especially to young and multipara women, should be developed to further improve the utilization of the services at the community level.
