Extending persian sentiment lexicon with idiomatic expressions for sentiment analysis
Authors: Dashtipour Kia , Gogate Mandar , Gelbukh Alexander , Hussain Amir 
Published: November 2021

AbstractNowadays, it is important for buyers to know other customer opinions to make informed decisions on buying a product or service. In addition, companies and organizations can exploit customer opinions to improve their products and services. However, the Quintilian bytes of the opinions generated every day cannot be manually read and summarized. Sentiment analysis and opinion mining techniques offer a solution to automatically classify and summarize user opinions. However, current sentiment analysis research is mostly focused on English, with much fewer resources available for other languages like Persian. In our previous work, we developed PerSent, a publicly available sentiment lexicon to facilitate lexicon-based sentiment analysis of texts in the Persian language. However, PerSent-based sentiment analysis approach fails to classify the real-world sentences consisting of idiomatic expressions. Therefore, in this paper, we describe an extension of the PerSent lexicon with more than 1000 idiomatic expressions, along with their polarity, and propose an algorithm to accurately classify Persian text. Comparative experimental results reveal the usefulness of the extended lexicon for sentiment analysis as compared to PerSent lexicon-based sentiment analysis as well as Persian-to-English translation-based approaches. The extended version of the lexicon will be made publicly available.

introduced by C. Calderón et al. in an earlier work, which are common eigenfunctions of a differential operator of hypergeometric type. Specifically, we give a Rodrigues formula that allows us to write this family of polynomials explicitly in terms of the classical Jacobi polynomials, and write, for the sequence of orthonormal polynomials, the three-term recurrence relation and the Christoffel–Darboux identity. We obtain a Pearson equation, which enables us to prove that the sequence of derivatives of the orthogonal polynomials is also orthogonal, and to compute a Rodrigues formula for these polynomials as well as a matrix-valued differential operator having these polynomials as eigenfunctions. We also describe the second-order differential operators of the algebra associated with the weight matrix.
The Mystery of Remote Communality: University Students’ and Teachers’ Perceptions During the COVID-19 Pandemic
Authors: Uusiautti Satu , Hyvärinen Sanna , Björkman Sina 
Published: November 2021

AbstractThe aim of this study was to examine how the coronavirus disease (COVID-19) pandemic affected the communality among university personnel and students. Herein, we report the findings from a northern Finnish university in which student (mean number of participants, n = 339) and staff (mean number of participants, n = 133) perceptions and experiences were surveyed. The data (gathered between March 2020 and June 2021 in 7 surveys) included responses to questions about satisfaction with remote and hybrid work and communality. In addition, as the focus of the analysis in this research, we collected the participants’ descriptions of their experiences and thoughts through open-ended questions. The sense of communality among the students, students and teachers, and staff differed, but the appreciation for flexible interactions and availability was similar between the groups. This study discusses the importance of retaining a sense of communality during and after abnormal times on the basis of the reported findings.
A review on advances in doping with alkali metals in halide perovskite materials
Authors: Tabassum Madeeha , Zia Qasim , Zhou Yongfeng , Reece Michael J. , Su Lei 
Published: November 2021

AbstractRecent progress in doping of halide perovskite materials (HPM) by using targeted elements has provided a dimension beyond structural and compositional modification, for achieving desired properties and resulting device performance. Herein doping of alkali metal ions (Li+, Na+, K+, Rb+, and Cs+) in three-dimensional HPM is reviewed to lay a particular focus on advances in synthesis, doping-induced changes in optical and electrical properties, and their optoelectronic applications. The introduction of alkali metals in HPM shows an effective route for improved morphology, suppressed ion migration, reduction in non-radiative recombination, passivation of bulk and interface defects, and increased thermal stability. In the end, we provide our perspective that the effect of alkali metal incorporation on the efficiency and stability of HPM should be further investigated via in-situ characterization methods and doped HPM should be considered for more functional applications.

bZIP17 regulates heat stress tolerance at reproductive stage in Arabidopsis
Authors: Gao Juan , Wang Mei-Jing , Wang Jing-Jing , Lu Hai-Ping , Liu Jian-Xiang 
Published: November 2021

AbstractHigh temperature elicits a well-conserved response called the unfolded protein response (UPR) to bring protein homeostasis in the endoplasmic reticulum (ER). Two key UPR regulators bZIP28 and bZIP60 have been shown to be essential for maintaining fertility under heat stress conditions inArabidopsis, however, the function of transcriptional activator bZIP17, a paralog of bZIP28, in heat stress response at reproductive stage is not reported. Here we found thatbzip17mutant plants were sensitive to heat stress in terms of silique length and fertility comparing to that of wildtype (WT)Arabidopsisplants, and transcriptomic analysis showed that 1380 genes were specifically up-regulated and 493 genes were specifically down-regulated by heat stress in the flowers of WT plants comparing to that inbzip17mutant plants. These bZIP17-dependent up-regulated genes were enriched in responses to abiotic stresses such as water deprivation and salt stress. Further chromatin immuno-precipitation coupled with high-throughput sequencing (ChIP-Seq) uncovered 1645 genes that were direct targets of bZIP17 inMYC-bZIP17expressing seedlings subjected to heat stress. Among these 1645 genes, ERSE-IIcis-element was enriched in the binding peaks of their promoters, and the up-regulation of 113 genes by heat stress in flowers was dependent on bZIP17. Our results revealed direct targets of bZIP17 in flowers during heat stress responses and demonstrated the important role of bZIP17 in maintaining fertility upon heat stress in plants.

Sexual Desire, Depressive Symptoms and Medication Use Among Women With Fibromyalgia in Flanders
Authors: Van Overmeire Roel , Vesentini Lara , Vanclooster Stephanie , Muysewinkel Emilie , Bilsen Johan 
Published: November 2021

Abstract

Background
Fibromyalgia (FM) is associated with sexual dysfunction, though much less is known about the sexual desire, and especially dyadic and solitary sexual desire, among women with fibromyalgia.

Aim
To investigate on the one hand the global sexual desire, the dyadic sexual and solitary sexual desire, and on the other hand the association with depressive symptoms, fibromyalgia symptoms and medication use among women with fibromyalgia in Flanders, Belgium.

Methods
An online survey was spread through the Flemish league for Fibromyalgia Patients to be completed by women with fibromyalgia. The sexual desire inventory-2 (SDI-2) was used to measure sexual desire (global, dyadic, solitary), the VASFIQ for fibromyalgia symptoms, and the PHQ-2 for depressive symptoms, while also including questions on demographic factors (time since FM, age) and medication usage (antidepressants, pain medication, sleeping medication).

Main Outcome Measure
Global sexual desire, dyadic sexual desire and solitary sexual desire were studied in relation to depressive symptoms, medication use and fibromyalgia symptoms.

Results
One hundred and three women with FM answered the survey. Depressive symptoms were significantly associated with a lower global, dyadic and solitary sexual desire, as was the use of antidepressant medication. The association between solitary sexual desire and depressive symptoms disappeared when controlled for antidepressant medication. Age, fibromyalgia symptoms nor time since diagnosis were significantly associated with any form of sexual desire.

Conclusion
Depressive symptoms and antidepressant medication, and not fibromyalgia symptoms, were associated with decreased sexual desire of women with FM. As antidepressant medication and depressive symptoms are associated with a decreased sexual desire, more attention should be paid towards the mental health issues associated with fibromyalgia, as well as the prescription of antidepressant medication. This study is the first to investigate sexual desire among women with fibromyalgia in Flanders, and one of the few internationally to have done so. It is limited by its cross-sectional design, and for not providing information on men with FM.

Published: November 2021

AbstractObjectiveThis study aimed to compare the mood state of patients with severe pelvic organ prolapse (POP) before and after surgery.MethodsThis prospective study enrolled 100 patients with severe POP who were surgically treated between October 2016 and February 2019. The clinical severity of POP was evaluated using the POP Quantification (POP-Q) System. Mood state evaluation, using the Hamilton anxiety (HAMA) and the Hamilton depression (HAMD) scale, was performed preoperatively and at 3 and 6 months postoperatively.ResultsThe POP-Q stage was significantly improved postoperatively (P ​< ​0.05). Preoperatively, the patients had varying degrees of anxiety symptoms (mean HAMA score, 11.94 ​± ​5.59 points) and depression symptoms (mean HAMD score, 5.56 ​± ​2.58 points); these scores were significantly decreased at 3 months (mean HAMA score, 4.67 ​± ​2.02 points; mean HAMD score, 3.58 ​± ​1.61 points) and 6 months postoperatively (mean HAMA score, 4.88 ​± ​2.57 points; mean HAMD score, 3.38 ​± ​1.60 points) (P ​< ​0.05). There were no differences in the HAMD and HAMA scores in both traditional prolapse surgery patients and mesh pelvic reconstruction patients preoperatively and at 3 and 6 months postoperatively (P＞0.05).ConclusionsPatients with severe POP have different anxiety and depression symptoms preoperatively. Successful individualized surgical treatment is effective for improving the clinical severity of severe POP and might alleviate or improve POP-related anxiety or depression symptoms.
“Is that for here or to go?” Drive-Through Pediatric Vaccine Clinic as a Novel Approach during a Global Pandemic
Authors: Patil Sowmya , Kerby Karalyn , Ramick Amy , Criddle Justin H. 
Published: November 2021

Abstract

Objective:
Routine childhood vaccination and well-child visits are essential for pediatric patients’ preventative and public healthcare services. The COVID-19 pandemic had an immediate and significant decline in well-child visits and vaccine administration. A one-of-a-kind ‘Drive-Through Vaccine Clinic’ was established to improve the vaccination rate and alleviate parental anxiety about being exposed to COVID-19 infection.

Methods:
Our initial focus was on children between 18 months – 4 years of age at the start of the pandemic, and then extended this to the back-to-school vaccines and the Influenza vaccines.

Results:
The Drive-Through Immunization Station provided 745 vaccines to 415 patients between April and September, 2020. The median wait time involved from patient arrival to completion of vaccine administration was 5 minutes at the Drive-Through location. Patient and parent feedback was positive. The addition of the Drive-Through Clinic helped to significantly increase the total number of vaccines administered compared to the previous year.

Conclusion:
In a global pandemic, innovative ideas to increase access to preventive healthcare should be a priority. In the future, this method of non-traditional vaccine administration, will allow for improved outreach efforts to underserved populations in our communities, and better disaster preparedness.
Female slam poets of francophone Africa: spirited words for social change
Authors: de Bruijn Mirjam , Oudenhuijsen Loes 
Published: November 2021

AbstractSlam poets in Africa are part of an emerging social movement. In this article, the focus is on women in this upcoming slam movement in francophone Africa. For these women, slam has meant a change in their lives as they have found words to describe difficult experiences that were previously shrouded in silence. Their words, performances and engaged actions are developing into a body of popular knowledge that questions the status quo and relates to the ‘emerging consciousness’ in many African urban societies of unequal, often gendered, power relations. The women who engage in slam have thus become a voice for the emancipation of women in general.
Vernacular historiography and self-translation in early colonial Nigeria: Ajiṣafẹ's History of Abẹokuta
Authors: Deese Adrian M. 
Published: November 2021

AbstractEmmanuel Olympus Moore (aka Ajiṣafẹ) (c.1875/79–1940) was a pioneer of Nigerian Yorùbá literature and popular music. Ajiṣafẹ was one of the most significant Nigerian popular cultural figures of his generation. Written during the amalgamation of Nigeria, his History of Abẹokuta (1916) (Iwe Itan Abẹokuta, 1924) is a seminal text for our understanding of Abẹokuta and the Ẹgba kingdom. This article examines the bilingual passages of the History in which Ajiṣafẹ invokes oral history to construct a religious ethnography of the early Ẹgba polity. Self-translation enabled vernacular authors to mediate constituencies. The English and Yorùbá texts of the History differ in their engagement with Yorùbá cosmology. Ajiṣafẹ's texts converge in his defence of the Odùduwà dynasty; Abẹokuta, in a constitutional Yorùbá united kingdom, would be the seat of ecclesiastical power. Civil authority in Nigeria could be stabilized through an Abrahamic renegotiation of divine kingship. To establish his treatise within a genealogy of world Christianity, Ajiṣafẹ utilized self-translation as a rhetorical device to reconcile the working of providence in precolonial and colonial African history. Ajiṣafẹ's History, ultimately, is an Abrahamic exposition of the role of God's providence in bringing about the complete unification of Nigeria in September 1914.
A contested financial frontier: banking and empire building in Eritrea,c.1952–73
Authors: Puddu Luca 
Published: November 2021

AbstractThis article provides an account of the relationship between imperial Ethiopia and Eritrea in the realm of banking governance from the start of the federation to the last years of the imperial regime. It looks in particular at the relationship between the Ethiopian administrations and an Italian bank, Banco di Roma, which had its headquarters in Eritrea from 1948 to 1967 before moving to Addis Ababa. The struggle for control of the economic flows generated by the Italian bank is an index of the changes in centre–periphery linkages between Addis Ababa and the sub-regional centre of Asmara. Archival evidence highlights the multifaced nature of Ethiopian governance and the role performed by the Italian institution in providing alternative sources of diplomatic leverage and wealth accumulation to the Eritrean elite. It is argued that the extraterritorial status enjoyed by Banco di Roma until 1967 was actively tolerated by a section of the Ethiopian establishment, which resorted to an established pattern of imperial governance based on flexibility in return for tribute. This centre–periphery arrangement was harshly opposed by prominent Ethiopian officials from the Ministry of Finance and the National Bank of Ethiopia, who struggled to enforce tighter government control over capital flows within and across the country's borders. The National Bank's final success in the quest for financial centralization drained significant resources out of Eritrea, with adverse effects on the preservation of thepax aethiopicain the former Italian colony.
Miocene to sub-Recent magmatism at the intersection between the Dead Sea Transform and the Ash Shaam volcanic field: evidence from the Yarmouk River gorge and vicinity
Authors: Segev Amit , Reznik Itay J. , Schattner Uri 
Published: November 2021

AbstractThe Yarmouk River gorge extends along the Israel–Jordan–Syria border junction. It marks the southern bound of the Irbid–Azraq rift and Harrat Ash Shaam volcanic field at their intersection with the younger Dead Sea Transform plate boundary. During the last ∼13 Ma, the gorge has repeatedly accumulated basaltic units, chronologically named the Lower, Cover, Yarmouk and Raqqad Basalt formations. We examined their origin and distribution through aerial photos, and geological and geophysical evidence. Our results define a southern Golan magmatic province, which includes exposed Miocene (∼13 Ma) basalts, gabbro–diabase intrusions below the gorge and the adjacent Dead Sea Transform valley, and numerous Pliocene–Pleistocene volcanic sources along the gorge. Cover Basalt (∼5.0–4.3 Ma) eruptions formed two adjacent 0–100 m thick plateaus on the transform shoulder before flowing downslope to fill the topographically lower Dead Sea Transform valley with ∼700 m thick basalts. Later incision of the Yarmouk River and displacement along its associated fault divided the plateaus and formed the gorge. The younger Yarmouk (0.8–0.6 Ma) and Raqqad (0.2–0.1 Ma) basalts erupted in the upper part of the gorge from volcanos reported here, and flowed downstream toward the Dead Sea Transform valley. Consequently, eruptions from six phreatic volcanic vents altered the Yarmouk River morphology from sinuous to meandering. Our results associate the ∼13 Ma long southern Golan volcanism with the proposed SW-trending extensional Yarmouk Fault, located east of the Dead Sea Transform. Hence, the Yarmouk volcanism is associated with the ongoing Harrat Ash Shaam activity, which is not directly linked to the displacement along the Dead Sea Transform.

Published: November 2021

AbstractObjectiveThis retrospective study was undertaken to assess the outcome of the medical and/or surgical management of patients presenting with clinical features of arytenoid granuloma.MethodsThe records of 53 males and 9 females were reviewed for predisposing factors, types of treatment received and recurrence following the treatment.ResultsMost of the patients (48 out of 62, 77.4 per cent) were treated conservatively with medical management and voice therapy, which resulted in complete resolution of arytenoid granuloma in over two-thirds of the patients treated (32 out of 48, 66.6 per cent). Overall, 28 patients (out of 62, 45.1 per cent) required surgery (14 failed medical treatment cases and 14 surgery as first-line treatment cases). Of these, five patients (out of 28, 17.9 per cent) had recurrence, and were managed with revision surgery and concurrent local injection of Botox.ConclusionAnti-reflux medication and voice therapy are effective first-line management options. Pre- and post-surgery adjuvant treatment improves the results of surgery. Local injection of Botox was successful in the treatment of failed surgical cases.
Distance between the middle turn of the cochlea and labyrinthine portion of the facial nerve: a surgical-radiological comparison and assessment of clinical importance
Authors: Lakhawat R , Grover M , Sharma S , Charan M , Lohar N , Samdani S 
Published: November 2021

AbstractObjectiveTo highlight the close anatomical relationship between the middle turn of the cochlea and the labyrinthine segment of the facial nerve, which will be helpful to predict the probability of occurrence of facial nerve stimulation following cochlear implant surgery.MethodsHigh-resolution computed tomography of 40 cadaveric temporal bones was performed, followed by microscopic dissection. Cochleo-facial distance was measured with the help of a Digital Imaging and Communications in Medicine (‘DICOM’) viewer on high-resolution computed tomography and by a millimetre scale in the dissected specimen.ResultsThe cochleo-facial distance on high-resolution computed tomography was 0.62 ± 0.09 mm, ranging from 0.41 to 0.81 mm, and on dissection it was 0.57 ± 0.10 mm, ranging from 0.35 to 0.74 mm.ConclusionThe labyrinthine segment is the most likely area of stimulation in patients suffering from facial nerve stimulation following cochlear implantation. Pre-operative high-resolution computed tomography of the temporal bone can be used to examine the bone separating the labyrinthine segment of the facial nerve from the middle turn of the cochlea. This has clinical significance regarding implant side selection and pre-operative patient counselling.

Published: November 2021

AbstractCase reportA 43-year-old woman presented with a 3-week history of globus sensation and malaise. A computed tomography scan of her neck showed a large right paratracheal abscess secondary to an infected tracheal diverticulum. The patient was admitted under the ENT surgical team, and underwent incision and drainage of the abscess. There were no post-operative complications and she was discharged home after 2 days, on oral antibiotics.ConclusionThis case demonstrates that a tracheal diverticulum may become infected and present as a cervical abscess. To our knowledge, this is the fourth reported case in the international literature of abscess formation related to an infected tracheal diverticulum.
Impact of tonsillotomy versus tonsillectomy on health-related quality of life and healthcare costs in children with sleep-disordered breathing

Published: November 2021

AbstractObjectiveThis study aimed to explore health-related quality of life and use of healthcare services and ensuing costs before and after tonsillotomy in children with sleep-disordered breathing and to compare the results to an earlier cohort of children who had undergone tonsillectomy.MethodChildren undergoing tonsillotomy answered the 17-dimensional, standardised health-related quality of life instrument questionnaire and a questionnaire on use of healthcare services and sick leave before and after surgery. Costs of specialist care were obtained pre- and post-operatively. The data were compared with similar data collected previously from children with tonsillectomy.ResultsTonsillotomy improved mean total health-related quality of life score significantly at 6 and 12 months. Healthcare costs and number of sick-leave days diminished significantly from 3 months pre-operatively to 12 months after surgery. Tonsillotomy had similar positive effects compared with tonsillectomy regarding health-related quality of life and healthcare costs.ConclusionTonsillotomy improves health-related quality of life in children with sleep-disordered breathing and reduces healthcare service needs and sick leave similarly to tonsillectomy.
