Published: October 2021

Due to the extreme insistence for digital image processing, plentiful modern noise suppressing techniques are embodied of dissimilarity process and suppressing process. One of the extreme capability dissimilarity is hard decision threshold (HDT) dissimilarity, which has been recently declared in 2012, for suppressing the impulsive noisy photographs thus the computer experimental statement attempts to investigate the capability of the noise suppressing technique that is stand on HDT dissimilarity for the processed photographs, which are corrupted by fixed-intensity impulse noise (FIIN). This paper proposes the noise suppressing technique stand on HDT dissimilarity for FIIN. There are 3 primary contributions of this paper. The first contribution is the statistical average of the HDT dissimilarity of noise-free elements, which are computed from plentiful ground-truth photographs by varying window size for the best HDT window size. The second contribution is the statistical average of the HDT dissimilarity of corrupted elements, which are computed from plentiful corrupted photographs by varying outlier density for the best HDT window size. The final contribution is the statistical interrelation of the capability of the noise suppressing technique and hard consistent of HDT dissimilarity are investigated by varying the outlier denseness for the best HDT hard consistence.

Published: October 2021

Analysis and classification of raga is the need of time especially in music industry. With the presence of abundance of multimedia data on internet, it is imperative to develop appropriate tools to classify ragas. In this work, an attempt has been made to use occurrence pattern of pitch based svara (note) for classification. Sequence of notes is an important cue in the raga classification. Pitch based svara (note) profile is formed. This pattern presents in the signal along with its statistical distribution can be characterized using co-occurrence matrix. Proposed note co-occurrence matrix summarizes this aspect. This matrix captures both tonal and temporal aspects of melody. Ragas differ in terms of distribution of spectral power. K-nearest neighbor (KNN) has been used as the classifier. Publicly available database consisting of 300 recordings of 30 Hindustani ragas consisting of 130 hours of audio recordings stored as 160 kbps mp3 fileswhich is part of CompMusic project is used. Leave one out validation strategy is used to evaluate the performance. Experimental result indicates the effectiveness of the proposed scheme which is giving accuracy of 93.7%.

Published: October 2021

A well Fifth generation (5G) mobile networks have been a common phrase in recent years. We have all heard this phrase and know its importance. By 2025, the number of devices based on the fifth generation of mobile networks will reach about 100 billion devices. By then, about 2.5 billion users are expected to consume more than a gigabyte of streamed data per month. 5G will play important roles in a variety of new areas, from smart homes and cars to smart cities, virtual reality and mobile augmented reality, and 4K video streaming. Bandwidth much higher than the fourth generation, more reliability and less latency are some of the features that distinguish this generation of mobile networks from previous generations.  Clearly, at first glance, these features may seem very impressive and useful to a mobile network, but these features will pose serious challenges for operators and communications companies. All of these features will lead to considerable complexity. Managing this network, preventing errors, and minimizing latency are some of the challenges that the 5th generation of mobile networks will bring. Therefore, the use of artificial intelligence and machine learning is a good way to solve these challenges. in other say, in such a situation, proper management of the 5G network must be done using powerful tools such as artificial intelligence. Various researches in this field are currently being carried out. Research that enables automated management and servicing and reduces human error as much as possible.

A novel secure biomedical data aggregation using fully homomorphic encryption in WSN
Authors: G. Chethana , V. Padmaja K.
Published: October 2021

A new method of secure data aggregation for decimal data having integer as well as fractional part using homomorphic encryption is described. The proposed homomorphic encryption provides addition, subtraction, multiplication, division and averaging operations in the cipher domain for both positive and negative numbers. The scheme uses integer matrices in finite field Zp as encryption and decryption keys. An embedded Digital signature along with data provides data integrity and authentication by signature verification at the receiving end. The proposed scheme is immune to chosen plaintext and chosen ciphertext attacks. In the case of homomorphic multiplication, the ciphertext expansion ratio grows linearly with the data size. The computational complexity of the proposed method for multiplication and division is relatively less by 22.87% compared to Brakerski and Vaikantanathan method when the size of the plaintext data is ten decimal digits.

Published: October 2021

The present project is motivated by the recognition that the use of mobile fitness application is increasingly popular among sports and exercise participants in recent years. However, an extensive research on mobile fitness application indicates that most of them are not suitable for beginners. Thus, this project paper describes the development process of a mobile fitness application for beginners, who are looking at enhancing their physical fitness level. This mobile fitness application is developed using android studio and java language. Upon the development of this mobile fitness application, a user testing was conducted and analyzed. The result shows that users were satisfied with the applications as most test scores were above average. Based on these results, the usage of this newly developed mobile fitness application can be suggested to be used by beginner exercisers.
Development of ontology-based model to support learning process in LMS
Authors: Ghanim Hussein Ali Ahmed , Kovács László
Published: October 2021

E-Learning is an important support mechanism for educational systems to increase the efficiency of the education process including students and teachers. The current e-learning systems typically lack the level of metacognitive awareness, adaptive tutoring, and time management skills and have not always met the expectations of the learners as required. In this study, we introduce a novel ontological model for the learning process in the e-learning domain. In the framework, we have built a domain ontology that represents knowledge of the learning, the outcome domain ontology covers the whole learning process. We focused on the learning process ontology model conceptualizing knowledge constructions, such as learning courses, and we present the created course and learning process ontology in detail. In this work, we considered three layers of learning process. The top layer defines a general framework of learning process, conceptual model layer, defines the framework of the actual process of the learning process and course ontology model contains the knowledge unit of the learning process. The prototype ontology is constructed in protégé and managed by Java web ontology language-application programming interface (OWL-API). As a result, our model can solve the problems of current e-tutor systems. Also, it can be used for different domain in e-tutor systems. It can reach the characteristics of standardization, reusability, flexibility, and open knowledge. By applying this model, we can avoid applying isolated databases. The constructed ontology can be used in the future to control adaptive intelligent e-tutor frameworks.

Published: October 2021

This study aims to develop a decision support system using the fuzzy method in order to assess the quality of education and training of prospective civil servants and highlight possible improvement considerations. The assessment consists of six criterias, namely coaches, lecturers, preachers, mentors, examiners, and administrators. Based on the evaluation result of the quality level of each criterion, it is obtained that the top two criterion are examiners and preachers, followed by coaches, lecturers, advisors, and the lowest is organizer. In addition, the quality of the civil servant class III training is better than the class II civil servant training. It also shows that the value of the organizers criterion has different level of satisfactions. Overall, the quality of the training (according to the participants' opinion) was very good with a score of 92.50 for training class II and 95.20 for training class III. Furthermore, it is necessary to conduct research to determine the quality of the training each year by looking at the achievements of the participants. The >system testing obtained an accuracy of 100%, whichs implies that the system can be used to assess the quality of education and training appropriately.

Published: October 2021

The paper presents a multiparameter aquaculture water quality tester with a decision support system. A device was developed to aid aquaculture farmers in monitoring water quality parameters and maintaining or achieving optimal levels by suggesting ways on how a farmer can respond to such measurements. The AQUACISION device measures six different water quality parameters; temperature, practical salinity, pH level, total dissolved solid (TDS), oxidation-reduction potential (ORP), and algae density. Measurements were sent to the AQUACISION application where they were processed to determine the course of action that was best to maintain or achieve optimal levels using fuzzy rules. Based on the comparative result, the AQUACISION was accurate in measuring temperature, practical salinity, pH level, TDS, and ORP during the actual testing. The application also received an excellent rating on the ISO/IEC 25010 software quality model standard
Machine learning for decoding linear block codes: case of multi-class logistic regression model
Authors: Imrane Chemseddine Idrissi , Said Nouh , Mehdi Bellfkih El , Seddiq El Kasmi Alaoui , Abdelaziz Marzak
Published: October 2021

Facing the challenge of enormous data sets variety, several machine learning-based algorithms for prediction (e.g, Support vector machine, multi layer perceptron and logistic regression) have been highly proposed and used over the last years in many fields. Error correcting codes (ECCs) are extensively used in practice to protect data against damaged data storage systems and against random errors due to noise effects. In this paper, we will use machine learning methods, especially multi-class logistic regression combined with the famous syndrome decoding algorithm. The main idea behind our decoding method which we call logistic regression decoder (LRDec) is to use the efficient multi-class logistic regression models to find errors from syndromes in linear codes such as bose, ray-chaudhuri and hocquenghem (BCH), and the quadratic residue (QR). Obtained results of the proposed decoder have a significant benefit in terms of bit error rate (BER) for random binary codes. The comparison of our decoder with many competitors proves its power. The proposed decoder has reached a success percentage of 100% for correctable errors in the studied codes.

Published: October 2021

Background and Purpose:

IV tPA (intravenous thrombolysis with alteplase) and mechanical thrombectomy (MT) utilization increased in acute ischemic stroke hospitalizations in the United States over the last decade. It is uncertain whether this increase occurred equally across all age, sex, and racial groups.

Methods:

Adult acute ischemic stroke hospitalizations (weighted n=4 442 657) contained in the 2008 to 2017 National Inpatient Sample were identified using
International Classification of Diseases
codes. Proportions of hospitalizations with IV tPA and MT were computed according to age, sex, and race. Joinpoint and multivariable-adjusted logistic regression models were used to evaluate trends over time.

Results:

Across this period, 32.4% of all hospitalizations were in patients ≥80 years, and 64.7% of these were women. IV tPA and MT use differed by age with highest proportion of utilization of both treatments in patients aged 18 to 39 years (IV tPA, 12.3%) and lowest percentage in patients aged ≥90 years (IV tPA, 7.9%). Utilization of both procedures increased over time in all age groups, but the pace of increase was faster in patients ≥90 years compared with patients aged 18 to 39 years (MT: odds ratio, 1.25 [95% CI, 1.20–1.35] per unit increase in year,
P
interaction <0.001). Frequency of utilization of IV tPA and MT was lower in Black patients compared with White patients in most age groups. Usage of both procedures increased over time in all races and after 2015, IV tPA utilization was >10% in all demographic subgroups except in Black patients 60 to 79 years and Black patients ≥80 years. Analysis of race-by-time interaction revealed the Black-vs-White treatment gaps for IV tPA (odds ratio, 1.02 [95% CI, 1.01–1.03]) and MT (odds ratio, 1.08 [95% CI,1.05–1.12]) declined over time (both
P
interaction <0.01). Sex-related differences in IV tPA use were noted, but this gap also declined over time.

Conclusions:

Age- and sex-related treatment gaps in IV tPA and MT reduced over the last decade. Racial disparity in IV tPA and MT utilization persists with particularly lower frequency of usage of both acute stroke treatments in Black patients compared with White patients, but race-associated treatment gaps also declined over time.

Published: October 2021

Introduction:

Post-anaesthesia care unit (PACU) delirium affects 5%–45% of patients after surgery and is associated with postoperative delirium and increased mortality. Up to 40% of PACU delirium is preventable, but it remains under-recognised due to a lack of awareness of its diagnosis. The nursing delirium screening scale (Nu-DESC) has been validated for diagnosing PACU delirium, but is not routinely used locally. This study aimed to use Nu-DESC to establish the incidence and risk factors of PACU delirium in patients undergoing non-cardiac surgery in the surgical population.

Methods:

We conducted an audit of eligible patients undergoing major surgery in three public hospitals in Singapore over 1 week. Patients were assessed for delirium 30–60 min following their arrival in PACU using Nu-DESC, with a total score of ≥2 indicative of delirium.

Results:

A total of 478 patients were assessed. The overall incidence rate of PACU delirium was 18/478 (3.8%), and the incidence was 9/146 (6.2%) in patients aged > 65 years. Post-anaesthesia care unit delirium was more common in females, patients with malignancy and those who underwent longer operations. Logistic regression analysis showed that the use of bispectral index (P < 0.001) and the presence of malignancy (P < 0.001) were significantly associated with a higher incidence of PACU delirium.

Conclusion:

In this first local study, the incidence of PACU delirium was 3.8%, increasing to 6.2% in those aged > 65 years. Understanding these risk factors will form the basis for which protocols can be established to optimise resource management and prevent long-term morbidities and mortality in PACU delirium.
Feeling Apart: Relations of Belonging in Tibetan Buddhist Lay-Monastic Communities
Authors: Caple Jane
Published: October 2021

Studies of belonging and community formation often emphasize commonality of values, emotions, and feelings. This article highlights the importance of practices that create relations of distance between members as well as closeness. Drawing on fieldwork in institutionalized Tibetan Buddhist communities in northeastern Tibet (Amdo/Qinghai), I focus on everyday practices of respect and faith that materialize community by putting monks, reincarnate lamas, and laity “in their place.” This can include the most quotidian of acts, such as standing when someone enters a room. I argue that such practices of “feeling apart” and their refusal are central to individual negotiations of religious belonging and to the dynamic, ongoing process of community formation. The importance of these practices becomes particularly apparent when, as is the case in northeastern Tibet, seemingly taken-for-granted relations of belonging and the emotional style that enacts and creates these relations are felt to be precarious.
Feeling the Way to Revelation: Patterns of Doubt and Persuasion in Tibetan Buddhist Auto/biographical Treasure Narratives
Authors: Townsend Dominique
Published: October 2021

In the Tibetan Buddhist Treasure (gter ma) tradition, communities cohere around the marking of certain visions as offering insight into the proper method of ritual practices, the veracity of reincarnation claims, decisions about institutional structures, assertions of lineage relationships, and most importantly for the purposes of this article, the phenomenology of Buddhist enlightenment for readers lacking such experience. There is a long and robust history of doubt around such visions and their narrative accounts. Doubters seek to debunk and disenfranchise those whose visions they dispute. This article analyzes the emotional dynamics and aesthetic charge of five exemplary visionary accounts from the 17th–20th century, with a focus on how doubts are overcome through intense positive sensory experiences within their life stories. Such narratives generate a sense of religious belonging in Tibetan Buddhist Treasure communities, beginning with the visionary him- or herself whose successful navigation of doubt is resolved by the persuasive power of intensely positive aesthetic experience.
Law and Justice among the Socratics: Contexts for Plato’s Republic
Authors: Horky Phillip Sidney
Published: October 2021

At the beginning of Republic 2 (358e–359b), Plato has Glaucon ascribe a social contract theory to Thrasymachus and ‘countless others’. This paper takes Glaucon’s description to refer both within the text to Thrasymachus’ views, and outside the text to a series of works, most of which have been lost, On Justice or On Law. It examines what is likely to be the earliest surviving work that presents a philosophical defence of law and justice against those who would prefer their opposites, On Excellence by an anonymous author usually referred to as ‘Anonymus Iamblichi’; the views on these topics among the Socratics, including Crito, Simon the Cobbler, Aristippus of Cyrene, and Antisthenes; and Socrates’ debate with Hippias ‘On Justice’ in Xenophon’s Memorabilia (4.4.5–25). Its main contention is that the ‘countless others’ referred to by Glaucon points chiefly, but not solely, to the members of the circle of Socrates, who themselves espoused a range of views on justice and law, and their relations.
What Aristotle Learned from Plato about Justice and Laws
Authors: Lee Mi-Kyoung
Published: October 2021

In this paper I consider Aristotle’s solutions to two questions about justice and the laws: why think that obeying the law is just? And why think that doing what is just will promote one’s happiness? I analyze Aristotle’s solutions to these two problems in terms of four claims concerning the laws that come from Plato and underwrite Aristotle’s optimism about the potential for politikê epistêmê to issue in laws which are objectively correct.
Spatial and temporal patterns of wound periderm development in Cryptomeria japonica bark

Published: October 2021

Limited investigations have been carried out on the physiological and growth responses of bark to wounding, even though wound periderms play crucial roles in tree defenses. To understand the mechanisms of wound periderm formation, we studied the growth responses and structural changes of wounded bark of three Cryptomeria japonica individuals. We observed the developmental time frame and morphology of wound periderms around mechanically induced wounds in summer. The wound responses included discoloration, lignification, and suberization in tissues present at the time of wounding, followed by wound periderm formation and secondary metabolite deposition. The trees had developed wound periderms approximately 4 weeks after wounding. The wound periderms were within 3 mm in the axial directions and within 1 mm in the lateral directions from the wound surfaces. The distinct patterns of wound periderm formation in the axial and lateral regions resulted from the arrangement and anatomical features of the cells adjacent to the wounds. The wound phellem cells were tangentially narrower and axially shorter in the side and upper/lower regions, respectively, of the wounds. Therefore, the cell division frequencies in the planes parallel to the wound surface may be greater than those in the other directions. Wound reactions in bark might initially be triggered by microenvironmental changes, such as the spread of desiccation, which depends directly on the morphology of phloem cell complexes.
Migration Infrastructure and Brokerage in Victorian Female Emigration Societies
Authors: Ruiz Marie
Published: October 2021

In the nineteenth century, female mobility was eased by a variety of intermediary structures, which interacted to direct the migration of British women to the Empire. Among these migration infrastructures were female emigration societies such as the Female Middle Class Emigration Society (1861–1886). This organisation was the first to assist gentlewomen in emigrating. It adopted a holistic approach to British female emigration by promoting women’s departure, selecting candidates, arranging their protection on the voyage, as well as their reception in the colonies. Grounded in a multifactorial perspective, this article offers an insight into how female migration brokerage came into being in the Victorian context. It intersects migration with gender and labour perspectives in a trans-sectorial approach of the history of female migration infrastructures in the British Empire, and reveals the diversity of transnational migration intermediaries interacting at meso level between female emigrants, non-state actors, and state institutions.
Leaving a Life Behind: Eliza Binemeciyan’s Encounter with “the Banality of Evil”
Authors: Kadıoğlu Ayşe
Published: October 2021

Among the Armenian actors who were essential in creating and sustaining Istanbul theaters at the turn of the twentieth century, Eliza Binemeciyan (1890-1981) emerged as a prominent one. In the aftermath of taking part in the play Kösem Sultan in 1912, she became the star of Istanbul theaters for more than a decade until she left her beloved city when she was 35 years old. She never returned to Istanbul, the city that was her home and where the remains of her parents, both well known Armenian actors, were buried. Her story as well as the stories of her Armenian colleagues reveal the decline of cosmopolitanism and the rise of nationalism in Istanbul. The change of scene in Istanbul theaters from multi-lingualism and cosmopolitanism to nationalism was like a microcosm of the policies of Turkification during the decline of the Ottoman Empire. In many memoirs about the era, Eliza Binemeciyan’s departure was normalized since she was depicted as an actor whose absence fostered the acting careers of Muslim Turkish women without much regard for her remarkable presence in Istanbul theaters.

Magnolia mixteca differs from M. nuevoleonensis in having larger flowers, longer petals, a yellow petal-blotch, a tan-sand coloured ovary and more numerous stamens and carpels. In addition, we provide a distribution map and key to species of sect. Macrophylla. The relict distribution of this species allows us to consider it endangered (E).
A new lichenicolous species of Carbonea (Ascomycota, Lecanoraceae) from northern Sweden
Authors: SVENSSON MÅNS , WESTBERG MARTIN
Published: October 2021

Carbonea is a widely distributed genus of lecideoid fungi, including both lichenized and non-lichenized, often parasitic species. We describe the new, non-lichenized species Carbonea tephromelae, based on material collected in the Swedish part of the Scandes. The new species is characterized by a colourless hypothecium, broadly ellipsoid to globose ascospores, and by growing on the thallus of the common saxicolous lichen Tephromela atra. It is similar to the likewise lichenicolous species C. supersparsa and C. vitellinaria, but is clearly separated from these species by anatomy and in a phylogenetic analysis based on four markers (mrSSU, ITS, RPB1, RPB2). Carbonea tephromelae is apparently specific to T. atra, but the use of host specificity as a character for species delimitation in lichenicolous species of Carbonea needs further evaluation.
A new species of Helmutkunzia Wells & Rao, 1976 from an intertidal sandy beach in Xiamen, China and proposal of Pseudobalucopsylla gen. nov. (Copepoda, Harpacticoida, Miraciidae)
Authors: MU FANGHONG , HUYS RONY
Published: October 2021

A new species of the genus Helmutkunzia Wells & Rao, 1976 (Miraciidae) is described from specimens collected from an intertidal sandy beach in Xiamen, Fujian Province, China. Helmutkunzia xiamenensis sp. nov. differs from its two congeners by the length/width ratio of the female P5 exopod, the number or length of the setae on the sexually dimorphic P2 endopod in the male and the relative length of the spines on the endopodal lobe of the male P5. The Chinese species is morphologically closest to H. variabilis Wells & Rao, 1987 from the Andaman and Nicobar island chain. Females of both species can readily be differentiated by the relative length of the P5 exopod while males can be differentiated by the length of the armature elements on P2 enp-2 and the endopodal lobe of P5. The genus Balucopsylla Rao, 1972 is reviewed, resulting in the proposal of Pseudobalucopsylla gen. nov. to accommodate the type species Balucopsylla triarticulata Wells & Rao, 1987 and three new Indo-Pacific species previously identified with it: P. obscura sp. nov. from the Andaman Islands, P. costaricensis sp. nov. from the Pacific coast of Costa Rica and P. mielkei sp. nov. from the Galápagos archipelago. A key to species of Pseudobalucopsylla sp. nov. is provided.
­On two new species of Nannopus Brady, 1880 (Copepoda: Harpacticoida: Nannopodidae) from intertidal mudflats of the Korean west coast (Yellow Sea)
Authors: VAKATI VINOD , LEE WONCHOEL
Published: October 2021

Two new species in the genus Nannopus Brady, 1880 (Copepoda: Harpacticoida) from intertidal mudflats of the Yellow Sea along the Korean peninsula, Nannopus cylindricus sp. nov. and N. robustus sp. nov., are described. Nannopus cylindricus belongs to the group of Nannopus species with seven elements on P4 exp-3. Within this group, it is closest to a cryptic species complex related to N. ganghwaensis Vakati, Kihara & Lee, 2016 based on an inflated caudal seta IV. However, N. cylindricus differs from the other species in this complex with respect to caudal seta V (inflated and heavily cylindrical at its base in N. cylindricus, inflated only in the N. ganghwaensis cryptic complex). Nannopus robustus belongs to the group of species displaying two setae on P2 enp-2. Within this group, N. robustus is closely related to N. serratus Vakati & Lee, 2017 based on the presence of one endopodal naked seta arising from a stem-like protrusion on the mandibular palp. However, N. robustus can be distinguished from N. serratus based on the following characters: outermost distal spine on P2 exp-3 (extremely strong, smooth and recurved in N. robustus, moderately strong, denticulate and normal-shaped in N. serratus, and spine 1.6 times as long in N. robustus as in N. serratus), P2 exp-2 inner seta (absent in N. robustus, present in N. serratus), shape of caudal seta V (anterior part distinctly cylindrical in N. robustus, normal-shaped in N. serratus), and ornamentation of caudal seta VI (naked in N. robustus, pinnate in N. serratus). An updated key to the 17 valid species of Nannopus is provided.

Authors: Pairawan Seyed S. , Olmedo Temich Luis , de Armas Sebastian , Folkerts Andrew , Solomon Naveen , Cora Cherie , Ramalingam Kirithiga , Lum Sharon S.
Published: October 2021

Background

In response to the COVID-19 pandemic, the American Society of Breast Surgeons and American College of Radiology released a joint statement recommending that all breast screening studies be postponed effective March 26, 2020.

Study Design

A retrospective review of all canceled mammograms at a single tertiary care institution from January 1-August 31, 2020 was performed to evaluate the effect of this recommendation by quantifying both the number and reason for mammogram cancellations before and after March 26, 2020. Utilization of the electronic patient portal for appointment cancellation as a surrogate for telehealth uptake was noted.

Results

During the study period, 5340 mammogram appointments were kept and 2784 mammogram appointments were canceled. From a baseline of 30 (10.8%) canceled mammograms in January, cancellations peaked in March (576, 20.6%) and gradually decreased to a low in August (197, 7%). Reasons for cancellations varied significantly by month ( P < .0001) and included COVID-19 related (236, 8.5%), unspecified patient reasons (1,210, 43.5%), administrative issues (147, 5.3%), provider requests (46, 1.7%), sooner appointments available (31, 1.1%), and reasons not given (486, 17.5%). In addition, compared to a baseline in January (51, 16.5%), electronic patient portal access peaked in August (67, 34.0%).

Conclusion

Screening mammogram cancellations have gradually recovered after early COVID-19 restrictions were lifted and increasing use of electronic patient access appears to be sustained. Consequences for future staging at the time of diagnosis remain unknown. Understanding to what extent the pandemic affected screening may help surgeons plan for post-pandemic breast cancer care.
Sensory Modulation and Participation in Daily Occupations in Stroke Survivors
Authors: Sharony Avivit Fuks , Engel-Yeger Batya
Published: October 2021

Background. Stroke may alter sensory modulation and restrict participation in daily occupations. Although studies highlight the relationship between altered sensory modulation and reduced participation, this relationship in stroke survivors has not been studied enough. Purpose. To examine the prevalence of altered sensory modulation among stroke survivors; to compare sensory modulation and participation between stroke survivors and healthy controls; to estimate the relationship between sensory modulation and participation among stroke survivors. Method. Thirty stroke survivors and 30 healthy controls, aged 18–70, completed the MoCA, the Adolescent-Adult Sensory Profile and the Activity Card Sort. Findings. Altered sensory modulation was more prevalent among stroke survivors. Their participation was significantly restricted as compared to healthy controls. Lower tendency to seek sensory input predicted lower participation in social activities. Implications. Occupational therapists should screen for altered sensory modulation in stroke survivors and understand their impacts on participation, in order to improve intervention outcomes.

Published: October 2021

This study identifid the most prominent risk factors associated with driving after cannabis use (DACU). 1,126 Canadian drivers (17–35 years old) who have used cannabis in the past 12 months completed an online questionnaire about sociodemographic information, substance use habits, cannabis effect expectancies, driving behaviours and peers’ behaviours and attitudes concerning DACU. A hierarchical logistic regression allowed identifying variables that were associated with DACU. Income (CA$30,000–CA$69,000), weekly-to-daily cannabis use, higher level of cannabis-related problems, expectation that cannabis facilitates social interactions, drunk driving, belief that DACU is safe, general risky driving behaviours, having a few friends who had DACU and injunctive norms predicted past 12-month DACU. Older age, holding negative expectations concerning cannabis, driving aggressively and perceived accessibility of public transportation decreased the probability of DACU. With restricted resources, programmes will be more efficient by targeting Canadian young adults most inclined to DACU by focussing on these risk factors.

Although the long-standing debate about the meaning of hilastērion in Rom. 3.25 has led to no consensus, readings are nearly always either (1) metaphorical ( hilastērion as place of atonement/expiation) or (2) metonymic ( hilastērion as a means of atonement/expiation). However, in many Second Temple Jewish texts, the word refers to a place of divine revelation. Proposing a fresh semantic topology of usages of hilastērion, this article argues that there is no unambiguous metonymic usage of the word, and that references to atonement in Lev. 16 are secondary to the revelatory function of the ‘mercy seat’. Attending to overlooked intertextual complexities, it suggests that the hilastērion was the site where God promised to reveal the definitive interpretation of his law. The revelatory function of the hilastērion possesses prima facie plausibility as a reading of Rom. 3.21-26, which is driven by the theme of God’s self-revelation in Jesus.

Background:

Fragility analysis is increasingly utilized to evaluate the robustness of results within the orthopaedic literature and has frequently revealed instability of reported outcomes.

Purpose/Hypothesis:

The purpose of this investigation was to utilize a fragility analysis to evaluate the stability of reported results in the patellofemoral instability (PFI) literature. We hypothesized the demonstration of significant fragility in patellofemoral research to be similar to that identified throughout other areas of the orthopaedic literature.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

The PubMed database was queried from January 1, 2000, to October 10, 2020 for comparative trials in 10 prominent orthopaedic journals that reported dichotomous outcomes related to the management of PFI. The fragility index (FI) and the fragility quotient (FQ) were calculated for each individual outcome event, and the overall FI and FQ were determined for all included studies.

Results:

A total of 22 comparative studies comprising 11 randomized controlled trials and 11 nonrandomized trials were included for the analysis. A total of 75 outcome events underwent a fragility analysis and revealed a median FI and FQ of 3 (interquartile range [IQR], 1-5) and 0.043 (IQR, 0.018-0.081), respectively. Also 27% of included studies reported loss to follow-up greater than the overall FI, therefore suggesting the maintenance of the follow-up may have resulted in the reversal of significance.

Conclusion:

The result of the comprehensive fragility analysis demonstrated a lack of robustness in PFI research with the alteration of only a few outcome events required to reverse statistical significance. We therefore recommend the triple reporting of the P value, the FI, and the FQ to aid in the interpretation of the statistical integrity of future comparative trials in the PFI literature.

Are feelings of not mattering an antecedent of depressive symptoms, a consequence, or both? Most investigations focus exclusively on feelings of not mattering as an antecedent of depressive symptoms. Our current study examines a vulnerability model, a complication model, and a reciprocal relations model according to a cross-lagged panel model (CLPM) and a random-intercept cross-lagged panel model (RI-CLPM). A sample of 197 community adults completed the General Mattering Scale (GMS), the Anti-Mattering Scale (AMS), and a depression measure at three time points (i.e., baseline, 3 weeks, and 6 weeks). GMS and AMS scores were associated robustly with depressive symptoms at each time point. Other results highlighted the need to distinguish levels of anti-mattering and mattering. CLPM analyses supported a reciprocal relations model of anti-mattering (assessed by the AMS) and depressive symptoms and a complication model linking mattering (assessed by the GMS) and depressive symptoms. The RI-CLPM analyses provided tentative support only for a complication model of anti-mattering and depressive symptoms. Our findings highlight the differences between measures of the mattering construct and the need to adopt a temporal perspective that considers key nuances and the interplay among feelings of mattering, feelings of not mattering, and depression.

Evidence-based practices (EBPs) are strategies shown through rigorous experimentation to be effective when implemented as designed by educators in the field. The purpose of this review is to (a) describe the state and quality of evidence-based reviews and meta-analyses of studies on classroom and behavior management interventions for students with emotional and behavioral disorders (EBDs) and (b) summarize practices that can be deemed evidence-based. We identified 50 meta-analytic or systematic reviews encompassing 20 interventions implemented solely or in part with students with EBD. In total, our review identified eight interventions classified as EBPs for supporting students labeled with EBD in the meta-analytic literature. Implications for future research are presented.
Staying, leaving and returning: Trends of prevention of mother-to-child transmission retention among newly diagnosed HIV-positive pregnant and postpartum women

Published: October 2021

Uptake of services and retention throughout the Prevention of Mother-to-Child Transmission continuum are necessary to achieve the goal of reducing Mother-to-Child Transmission of Human Immunodeficiency Virus (HIV). Adopting a retrospective cohort design, we tracked the uptake of services in a district hospital in Ghana from antenatal booking through to six weeks postnatal when early infant diagnosis was conducted. Of the 1252 pregnant women booked antenatally, 94.1% ( n = 1178) received pre-test counselling, 96.3% (1134) opted for HIV testing and 3.8% ( n = 43) women tested positive for HIV throughout the continuum. The retention rate at six weeks postpartum was 67.4%. Missed opportunities occurred throughout the programme and the highest disengagement, 58.9% (23/39) occurred antenatally. Instances of re-engagement were also recorded. Establishing measures to promote retention throughout the programme is critical to ensuring HIV-infected mothers maintain their health and their exposed newborns are HIV-free. This phase of the study provided a comprehensive view of retention in the absence of any baseline.

Epidermodysplasia verruciformis (EV) is a rare cutaneous pre-cancerous condition characterized by presence of flat, scaly macules, verruca-like papillomatous papules, seborrheic keratosis-like lesions, and pink-red pityriasis versicolor-like macules. The disease is caused by abnormal susceptibility to certain specific beta-HPV subtypes, most commonly 5 and 8. Classic EV is genetically determined, but in immunocompromised individuals, an acquired form can occur. Only 48 cases of acquired EV (AEV) in people living with HIV have been described. We describe a case of AEV in a 36-year-old HIV-positive man with an history of stable optimal CD4 cell count and undetectable HIV viral load. The AEV significantly deteriorated after the administration of the second dose of the quadrivalent anti-HPV vaccine and did not improve despite local treatment, anti-HPV vaccination completion, and persistently optimal combined antiretroviral treatment adherence. To the best of our knowledge, this is the first report of an AEV deterioration with a clinical and temporal pattern mimicking an immune reconstitution inflammatory syndrome (IRIS) following anti-HPV vaccination, instead of low CD4 count restoration. After reviewing the current literature, we have hypothesized a vaccine-mediated IRIS-like phenomenon in the pathogenesis of the disease.
Market Backwardation and The Theory of Storage: An Empirical Investigation of Indian Gold Futures Markets
Authors: Nair Jyoti Raj , Kumar Brajesh , Inani Sarveshwar
Published: October 2021

The backwardation and contango in the futures markets are explained by two popular theories, namely the theory of storage and the theory of risk premium. The investment assets tend to follow the theory of risk premium, whereas the consumption assets are likely to follow the theory of storage. As India is the largest importer of gold, and gold is used for consumption purposes (mostly by jewellers, who store gold as a consumption commodity), we empirically test whether backwardation in the gold market is explained by the theory of storage. We use the indirect test of the theory of storage developed by Fama and French (1988 , Journal of Finance, Vol. 4, p. 1075), calculate the interest adjusted basis (IAB) and test the implications of the theory of storage. We also use two asymmetric models of the Generalized Autoregressive Conditional Heteroscedastic (GARCH) family to understand the asymmetric volatility of IAB. We find that the Indian gold futures markets partially follow the theory of storage; however, we do not find any support of asymmetric behaviour of IAB in the contango and backwardation markets. Our results suggest that in the context of the Indian gold market, keeping inventory has minimal benefits, and gold behaves more like an investment asset.
Preparing to Engage in Culturally Sustaining Practices in Urban Education Environments

It is important for special educators in urban environments to have a deep understanding of the values, beliefs, and practices of diverse students with disabilities and their families. Research indicates, however, that educators are often underprepared to understand the perspectives of members of their school community and often center their own perspectives on curricular decisions in urban environments. Therefore, it is important for special educators to engage in knowledge generation that provides them information about the assets and beliefs of their urban school community while also challenging their mindsets so that they can better center the perspectives of their students when making decisions. This column provides recommendations for special educators to prepare themselves by developing a deep understanding of their school community that they can use to subsequently link to the implementation of culturally sustaining practices.

To evaluate the current situation and associated factors of informational support for older adults with chronic diseases in transitional care. Study was conducted in five hospitals of five different cities in Jiangsu Province, China. A random cluster sample of 800 older adults with chronic diseases responded to the informational support questionnaire of transitional care survey. Descriptive analysis, t-tests, variance analysis, and stepwise multiple linear regression were used to analyze data. The STROBE statement for observational studies was applied. Total score of ISQTC for older adults with chronic diseases was (44.05 ± 17.21). Marital status, educational level, past occupation, close friends, medical insurance, complications, and exercise habits were significantly correlated with informational support. The level of informational support in transitional care for older adults with chronic diseases was low. Clinical staff should periodically and primarily assess their informational support, help find information resources for those who have low initial informational support, and identify which information they preferred to carry out accurate transitional care.
