Self-Corrective Autonomous Systems using Optimization Processes for Detection and Correction of Unexpected Error Conditions
Authors: D. Tam Nicoladie 
Published: February 2021

<p>A theoretical framework for autonomous self-detection and self-correction of unexpected error conditions is derived by incorporating the principles of operation in autonomous control in biological evolution. Using the biologically inspired principles, the time-dependent multi-dimensional disparity vector is used as a quantitative metric for detecting unexpected and unforeseeable error conditions without any external assistance. The disparity vector is a measure of the discrepancy between the expected outcome predicted by the autonomous system and the actual outcome in the real world. It is used as a measure to detect any unexpected or unforeseeable errors. The process for autonomous self-correction of the self-discovered errors is an optimization process to minimize the errors represented by the disparity vectors. The strategies for prioritizing the urgency of corrective actions are also provided in the theoretical derivations. The criteria for any change in direction of the corrective actions are also provided quantitatively. The criteria for the detection of the minimization and maximization of errors are also provided in the autonomous optimization process. The biological correspondences of the emotional responses in relation to the autonomic self-corrective feedback systems are also provided.</p>
Improvement on the association strength: Implementing a probabilistic measure based on combinations without repetition
Authors: Steijn Mathieu P. A. 
Published: February 2021

AbstractThe use of co-occurrence data is common in various domains. Co-occurrence data often needs to be normalized to correct for the size effect. To this end, van Eck and Waltman (2009) recommend a probabilistic measure known as the association strength. However, this formula, based on combinations with repetition, implicitly assumes that observations from the same entity can co-occur even though in the intended usage of the measure these self-co-occurrences are nonexistent. A more accurate measure based on combinations without repetition is introduced here and compared to the original formula in mathematical derivations, simulations, and patent data, which shows that the original formula overestimates the relation between a pair and that some pairs are more overestimated than others. The new measure is available in the EconGeo package for R maintained by Balland (2016).
Towards automated analysis of research methods in library and information science
Authors: Zhang Ziqi , Tam Winnie , Cox Andrew 
Published: February 2021

AbstractPrevious studies of research methods in Library and Information Science (LIS) lack consensus in how to define or classify research methods, and there have been no studies on automated recognition of research methods in the scientific literature of this field. This work begins to fill these gaps by studying how the scope of “research methods” in LIS has evolved, and the challenges in automatically identifying the usage of research methods in LIS literature. We collected 2,599 research articles from three LIS journals. Using a combination of content analysis and text mining methods, a sample of this collection is coded into 29 different concepts of research methods and is then used to test a rule-based automated method for identifying research methods reported in the scientific literature. We show that the LIS field is characterized by the use of an increasingly diverse range of methods, many of which originate outside the conventional boundaries of LIS. This implies increasing complexity in research methodology and suggests the need for a new approach towards classifying LIS research methods to capture the complex structure and relationships between different aspects of methods. Our automated method is the first of its kind in LIS, and sets an important reference for future research.
Description of Basilaphelenchus pedrami n. sp. (Tylenchomorpha: Aphelenchoididae) isolated from Kyoto, Japan
Authors: Kanzaki Natsumi 
Published: February 2021

Summary
An undescribed Basilaphelenchus species was isolated from the dead and decaying wood of an unidentified broad-leaved tree in Kyoto, Japan. The species was cultured on a lawn of Botrytis cinerea after many attempts and kept as a laboratory strain. The nematode is characterised by the position of its secretory-excretory pore, which differs between males (anterior to median bulb) and females (overlapping or posterior to median bulb), the tail morphology of males (conical with very short mucron) and females (smoothly tapering conical with various shapes at terminus) and male spicule morphology, with spicules possessing a smoothly curved blade (calomus-lamina complex) and a shallow capitulum depression. In addition, the new species is differentiated from other members of the genus by the molecular sequences of its ribosomal RNA region. Phylogenetically, the new species is close to two Iranian species, B. brevicaudatus and B. gorganensis, but can be distinguished from them based upon its separated phylogenetic status. The genus contains five species that were described from Chile and Iran. Thus, the isolation of a species from this genus in Kyoto, Japan, represents the first record of the genus from East Asia. The new species is described and illustrated herein as B. pedrami n. sp.
The Relationship Between Multisensory Temporal Processing and Schizotypal Traits
Authors: Dalal Tyler C. , Muller Anne-Marie , Stevenson Ryan A. 
Published: February 2021

Abstract
Recent literature has suggested that deficits in sensory processing are associated with schizophrenia (SCZ), and more specifically hallucination severity. The DSM-5’s shift towards a dimensional approach to diagnostic criteria has led to SCZ and schizotypal personality disorder (SPD) being classified as schizophrenia spectrum disorders. With SCZ and SPD overlapping in aetiology and symptomatology, such as sensory abnormalities, it is important to investigate whether these deficits commonly reported in SCZ extend to non-clinical expressions of SPD. In this study, we investigated whether levels of SPD traits were related to audiovisual multisensory temporal processing in a non-clinical sample, revealing two novel findings. First, less precise multisensory temporal processing was related to higher overall levels of SPD symptomatology. Second, this relationship was specific to the cognitive–perceptual domain of SPD symptomatology, and more specifically, the Unusual Perceptual Experiences and Odd Beliefs or Magical Thinking symptomatology. The current study provides an initial look at the relationship between multisensory temporal processing and schizotypal traits. Additionally, it builds on the previous literature by suggesting that less precise multisensory temporal processing is not exclusive to SCZ but may also be related to non-clinical expressions of schizotypal traits in the general population.

Published: February 2021

Background The incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) remains high. The present study aimed to clarify the efficacy of our modified DuVal (mDuVal) pancreatojejunostomy following DP in patients with a high risk of POPF. Methods The medical records of 346 consecutive patients who underwent DP between 2006 and 2016 were retrospectively reviewed. Perioperative features were compared between 24 patients undergoing mDuVal (mDuVal group) and 322 patients undergoing standard DP (standard DP group). Results Preoperative American Society of Anesthesiologists physical status 1 was more frequent in the standard group than in the mDuVal group ( P = .02). The start of a solid diet after operation was significantly earlier in the mDuVal group than in the standard DP group ( P = .01), while there were no significant differences between the groups for clinically relevant POPF, amylase concentration in the drainage fluid on postoperative day 1 and days 3-5, time to drain removal, additional intervention for POPF, overall complications, or postoperative hospital stay. Discussion The mDuVal procedure could be an option for patients with a high risk of POPF to improve the outcomes after DP. Further investigation involving large study populations is necessary to clarify the efficacy of this procedure.
The Expanded Core Curriculum Areas Experienced by Campers during Camp Abilities: A Qualitative Study

Published: February 2021

Introduction: The expanded core curriculum (ECC) refers to the generally accepted nine areas of instruction that children who are visually impaired (i.e., those who are blind or have low vision) must learn through explicit instruction in order to live independently as adults. Children with visual impairments must experience immersion in the ECC in their daily lives throughout the year rather than only being taught these skills during the school year by teachers of students with visual impairments. Therefore, this research was undertaken to determine whether athletes attending Camp Abilities, a sports camp for children with visual impairments, experienced new ECC skills or practiced previously learned ECC skills and if so, how. Method: Researchers chose to interview 10 athletes from a purposeful sample of 30 children who had previously attended camp. The 10 coaches who worked with these athletes one-on-one participated in focus group discussions at the end of the weeklong camp. In addition, all athletes and coaches attending camp listed their thoughts on posters describing how all athletes attending experienced areas of the ECC. Finally, researchers documented observations of athletes’ opportunities to practice ECC content throughout the weeklong program. Researchers transcribed interviews and focus group discussions and reviewed for themes relating to ECC areas that were part of the students’ lived experience during camp. Results: Three major conclusions emerged from reviews of the interviews, discussion group transcripts, posters, and observations: (1) athletes and coaches were initially unclear about what the ECC areas were and how the athletes experienced the ECC in their everyday academic and home activities; (2) following clarification of the ECC areas, the athletes came to recognize how they learned and applied ECC skills during the camp experience; and (3) a more structured instructional approach to applying the ECC at camp may further enhance their experiences. Discussion: The youth participants were not able to list and describe all of the ECC areas when interviewed at the end of camp. However, adult participants (coaches) listed most ECC areas and described how athletes experienced the ECC during camp in their focus group discussions. Once researchers clarified ECC areas for athletes, they identified self-determination, recreation and leisure, social interaction, and independent living as the areas of the ECC most often experienced during camp. Implications for practitioners: Practitioners need to pay attention to structured learning of the ECC areas and consider articulating for students which areas overlap in their everyday lives, so that they are fully aware of the multiple skills they are acquiring. Camp Abilities is a functional way for youths with visual impairments to experience all areas of the ECC.

Published: February 2021

Background Head and neck squamous cell carcinoma (HNSCC) is a common cancer. Positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) is a widely used imaging modality in HNSCC. Purpose To provide evident data about associations between 18F-FDG PET and histopathology in HNSCC. Material and Methods The MEDLINE database was screened for associations between maximum standard uptake values (SUVmax) derived from 18F-FDG PET and histopathological features in HNSCC up to May 2020. Only papers containing correlation coefficients between SUVmax and histopathology were acquired. Overall, 23 publications were collected. Results The following correlations were calculated: KI 67: 12 studies (345 patients), pooled correlation coefficient (PCC): 0.23 (95% confidence interval [CI] 0.06–0.40); hypoxia-inducible factor-1α: eight studies (240 patients), PCC: 0.24 (95% CI 0.06–0.42); microvessel density: three studies (64 patients), PCC: 0.33 (95% CI 0.02–0.65); vascular endothelial growth factor: two studies (59 cases), PCC: 0.27 (95% CI 0.02–0.51); tumor suppressor protein p53: four studies (159 patients), PCC: 0.05 (95% CI –0.41 to 0.51); epidermal growth factor receptor: two studies (124 patients), PCC: 0.21 (95% CI 0.05–0.37); tumor cell count: three studies (67 patients), PCC: 0.18 (95% CI –0.06 to 0.42); tumor cell apoptosis: two studies (40 patients), PCC: 0.07 (95% CI = –0.85 to 0.99); B-cell lymphoma-2 protein: two studies (118 patients); PCC: 0.04 (95% CI –0.65 to 0.74); glucose-transporter 1: 10 studies (317 patients), PCC: 0.20 (95% CI 0.10–0.30). Conclusion SUVmax derived from 18F-FDG PET cannot reflect relevant histopathological features in HNSCC.
Chair–CEO trust and firm performance
Authors: Zheng Jiayi , Zhu Yushu 
Published: February 2021

This study investigates whether trust between a corporation’s board chair and the CEO affects firm performance. After using a unique survey data set of regional trustworthiness from China to measure this trust, we find a positive relationship between trust and the performance of Chinese companies from 2000 to 2016. Additional test results suggest that the relationship is causal. Further results show that the positive trust-performance effect is more evident for firms with greater advisory needs and boards that can deliver high-quality advice. Finally, we find supporting evidence to our conjecture that the Chair–CEO trust increases firm value by improving the board advisory results, including value-adding decisions of R&D and merger and acquisition.

Published: February 2021

Background: Femoroacetabular impingement syndrome (FAIS) is an increasingly common diagnosis among working-age adults. Hip arthroscopy provides reliable improvements in pain and may allow patients to return to physical activities. No study to date has evaluated return to work (RTW) among a general population of adults after arthroscopic surgery for FAIS. Purpose: To evaluate (1) patients’ rate of RTW, (2) time required to RTW, and (3) factors correlated with time required to RTW after arthroscopic surgery for symptomatic FAIS. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients aged 25 to 59 years who underwent arthroscopic surgery for FAIS between June 2018 and December 2018 were reviewed. Workers’ compensation cases and patients with <1-year follow-up were excluded. The following were collected at a minimum of 1 year postoperatively: demographics, employment characteristics, Hip Outcome Score (HOS; Activities of Daily Living and Sports Specific subscales), modified Harris Hip Score, 12-Item International Hip Outcome Tool (iHOT-12), visual analog scale for pain, and RTW characteristics. Work physical activity level was classified as sedentary, light, moderate, heavy, or very heavy per established criteria. Results: A total of 97 patients were selected through inclusion and exclusion criteria. RTW surveys were collected for 79 (81.4%), and 61 were employed preoperatively. Time worked per week was 42.8 ± 12.5 hours (mean ± SD). Patients’ work level was most commonly classified as sedentary (42.6%), followed by moderate (24.6%). All 61 (100%) patients returned to work at a mean 7.3 weeks (range, <1-88 weeks) postoperatively. Sixty patients (95.2%) returned to full duty. Time required to full duty RTW was strongly correlated with expected time off from work ( r = 0.900; P < .0001) and moderately correlated with work classification ( r = 0.640; P = .0001). All patients had significant pre- to postoperative improvements in the HOS–Activities of Daily Living (64.8 ± 15.3 to 87.1 ± 12.2; P < .001), HOS–Sports Specific (42.8 ± 18.8 to 76.7 ± 16.5; P < .001), iHOT-12 (31.3 ± 18.8 to 69.3 ± 21.1; P < .001), modified Harris Hip Score (61.8 ± 12.1 to 80.3 ± 14.1; P < .001), and visual analog scale for pain (5.19 ± 2.11 to 2.40 ± 1.96; P < .001). Conclusion: Patients undergoing arthroscopic treatment for FAIS demonstrated a high rate of RTW at a mean of <2 months postoperatively. A patient’s expected time off from work and the level of physical demands required for work were highly associated with time required to RTW. These results are valuable for orthopaedic surgeons, patients, and employers when establishing a timeline for expected RTW after surgery.
High-Dose Daptomycin and Clinical Applications
Authors: Jones Timothy W. , Jun Ah Hyun , Michal Jessica L. , Olney William J. 
Published: February 2021

Objective: To evaluate evidence for high-dose daptomycin (doses ≥ 8 mg/kg/d). Data Sources: A PubMed/MEDLINE literature search was performed (January 2000 to December 2020) using the search terms daptomycin, high dose, and dosing. Review article references and society guidelines were reviewed. Study Selection and Data Extraction: Clinical trials, observational studies, retrospective studies, meta-analyses, and systematic reviews reporting on high-dose daptomycin were included. Data Synthesis: Experimentally, daptomycin outperforms other antimicrobials for high inoculum and biofilm-associated infections. Clinically, high-dose daptomycin is supported as salvage and first-line therapy for endocarditis and bacteremia, primarily when caused by methicillin-resistant Staphylococcus aureus (when vancomycin minimum inhibitory concentration is >1 mg/L) and Enterococcus. High-dose daptomycin appears effective for osteomyelitis and central nervous system infections, although comparative studies are lacking. High dosing in renal replacement therapy requires considering clearance modality to achieve exposures like normal renal function. Weight-based dosing in obesity draws concern for elevated exposures, although high doses have not been evaluated kinetically in obesity. Some data show benefits of high doses in overweight populations. Burn patients clear daptomycin more rapidly, and high doses may only achieve drug exposures similar to standard doses (6 mg/kg). Relevance to Patient Care and Clinical Practice: This review analyzes the efficacy and safety of high-dose daptomycin in serious gram-positive infections. Discussion of specific infectious etiologies and patient populations should encourage clinicians to evaluate their daptomycin dosing standards. Conclusions: The efficacy of high-dose daptomycin and limited safety concerns encourage clinicians to consider high-dose daptomycin more liberally in severe gram-positive infections.

Published: February 2021

Methods We administered the Global Neuropsychological Assessment (GNA), an abbreviated cognitive battery, to 105 adults aged 73.0 ± 7.1 years, including 28 with probable Alzheimer’s disease, 9 with amnestic mild cognitive impairment, and 68 healthy controls. We examined group differences in baseline performance, test–retest reliability, and correlations with other conventional tests. Results Healthy adults outperformed patients on all five GNA subtests. Test–retest intraclass correlation coefficients were significant for all GNA subtests. Among patients with healthy controls, GNA Story Memory correlated best with Wechsler Memory Scale–Revised (WMS-R) Logical Memory for learning and delayed recall, GNA Digit Span correlated most highly with the Wechsler Adult Intelligence Scale–Third Edition (WAIS-III) Digit Span, GNA Perceptual Comparison correlated most highly with the Trail Making Test, and GNA Animal Naming correlated most highly with Supermarket Item Naming. Conclusions Preliminary findings suggest that the GNA shows good test–retest validity, clear convergent and discriminant construct validity, and excellent diagnostic criterion validity for dementia and mild cognitive impairment in an American sample.
Do Independent Living Services Protect Youth Aging Out Foster Care From Adverse Outcomes? An Evaluation Using National Data
Authors: Huang Hui , Li Yong , Campbell John McKinley 
Published: February 2021

Objective: Youth aging out foster care are at high risk of experiencing adverse outcomes. Federal funded programs have provided independent living services (ILSs) to these youth. This study evaluated the effectiveness of the continuity of ILSs at ages 17–19 in protecting youth aging out foster care from homelessness and incarceration at ages 19–21. Method: This study used data on 4,853 foster youth from the National Youth in Transition Database and the Adoption and Foster Care Analysis and Reporting System. Logistic regression was used to regress two binary outcomes on seven ILS variables and covariates. Results: The results suggest that remaining in foster care, continuous receipts of academic support, and financial assistance services at ages 17–19 protected foster youth from experiencing homelessness. Remaining in foster care and continuous receipt of financial assistance services at ages 17–19 protected foster youth from incarceration at ages 19–21. But, surprisingly, continuous receipt of housing education and home management training, and health education and risk prevention training at ages 17–19 were each associated with increased risk of homelessness at ages 19–21. The results also showed statistically significant effects of several covariates. Conclusion: Implications are provided based on the importance of financial assistance and academic support services.
