Published: September 2021

Supporting instructor implementation of equitable and inclusive teaching approaches is a critical area of focus in educational development. However, there is limited empirical evidence on factors that either support or hinder instructors’ implementation of inclusive teaching. The results of this national survey study reveal several predictors of instructors’ utilization of inclusive teaching approaches and reported obstacles faced. For this sample, knowledge of inclusive teaching was a statistically significant predictor of implementation, as was being from a non-STEM discipline. Responses highlighted promising approaches, several of which can inform the efforts of educational developers.

Published: September 2021

Course design institutes (CDIs), which systematically guide faculty through the (re)design of courses, often transpire in an intensive residency or learning community format. Little is known, to date, of the long-term impact of such initiatives, particularly in the context of faculty motivation. This longitudinal study explores changes in faculty attitudes toward teaching, offering insight into the multifaceted gains and limiting factors influencing motivation as conceptualized by the expectancy-value-cost model (Barron & Hulleman, 2015). Findings reveal that CDI engagement bolsters the value placed on teaching, but arrives at a noteworthy cost to faculty. Implications for CTLs and instructional faculty are explored.

L’accompagnement, source de création de savoirs
Authors: Canivet Catherine , Cuche Catherine , Donnay Jean
Published: September 2021

Cet article tente de rencontrer un double enjeu. Même s’ils ne fonctionnent pas de la même manière, il s’agit de réaliser une lecture transversale de plusieurs types d’accompagnement d’élèves et d’étudiants en difficulté - qu’ils soient ou non à haut(s) potentiel(s) - de praticiens de l’enseignement - novices ou d’expérience - de conseillers pédagogiques et même d’accompagnement individuel ou en groupes d’équipes éducatives ainsi que d’établissements scolaires dans leur ensemble. Par ailleurs, nous proposons que le travail d’accompagnateur, voire de compagnonnage réflexif, confine à celui de chercheur et peut créer (co-créer) des savoirs de natures différentes dont certains peuvent être reconnus par une certaine communauté scientifique. Pour la clarté du texte, nous avons considéré plus spécialement l’accompagnement de praticien de l’enseignement, en nous concentrant sur les savoirs de l’accompagnateur-chercheur.
Entre recherche et formation des enseignants : travailler dans la zone de développement professionnel
Authors: Musquer Agnès , Fabre Michel
Published: September 2021

Un des problèmes inhérents à la formation des enseignants qu’elle soit initiale ou continue est celui de la préparation des activités d’apprentissage. Ceci pose la question des rapports que les enseignants entretiennent avec les savoirs à co-construire avec les élèves et avec les savoirs issus de la recherche, comme la situation-problème par exemple. Notre projet est d’amorcer un travail avec des enseignants pour comprendre ce qui fait difficulté dans leur pratique et plus particulièrement dans leur préparation de classe. C’est dans ce sens que la démarche suivie se voudra heuristique visant à observer ce qui se passe chez un sujet singulier (enseignant) pour découvrir les mécanismes cognitifs et professionnels à l’œuvre et envisager des aides. Il s’agira donc de repérer les difficultés qui émergent de l’élaboration de situations-problèmes. Nous comparerons les points communs et différences que nous pouvons repérer chez les enseignants concernés par ce dispositif. Puis, nous montrerons comment cette recherche a fait évoluer notre conception de la situation-problème.

Published: September 2021

Continuous novel ambulatory monitoring may detect deterioration in Emergency Department (ED) patients more rapidly, prompting treatment and preventing adverse events. Single-centre, open-label, prospective, observational cohort study recruiting high/medium acuity (Manchester triage category 2 and 3) participants, aged over 16 years, presenting to ED. Participants were fitted with a novel wearable monitoring device alongside standard clinical care (wired monitoring and/or manual clinical staff vital sign recording) and observed for up to 4 hours in the ED. Primary outcome was time to detection of deterioration. Two-hundred and fifty (250) patients were enrolled. In 82 patients (32.8%) with standard monitoring (wired monitoring and/or manual clinical staff vital sign recording), deterioration in at least one vital sign was noted during their four-hour ED stay. Overall, the novel device detected deterioration a median of 34 minutes earlier than wired monitoring (Q1, Q3 67,194; n=73, mean difference 39.48, p<0.0001). The novel device detected deterioration a median of 24 minutes (Q1, Q3 2,43; n=42) earlier than wired monitoring and 65 minutes (Q1, Q3 28,114; n=31) earlier than manual vital signs. Deterioration in physiology was common in ED patients. ED staff spent a significant amount of time performing observations and responding to alarms, with many not escalated. The novel device detected deterioration significantly earlier than standard care.

Hypercoagulability is a common complication of the systemic inflammation related to coronavirus disease 2019 creating debate within the critical care community on the therapeutic utility of Low Molecular Weight Heparin (LMWH). We collected data on consecutive patients with COVID-19 admitted to the Emergency Department of Castel San Giovanni Hospital, between February 29th and April 7th, 2020. Exclusion criteria were age <18 years, hospital stay <7 days, patients on dialysis and patients who had been transferred to other centers for which we could not collect data. Of the 257 patients included in the study, 49 (19.1%) died during hospitalization. We considered a wide set of variables as independent variables (age, sex, comorbidities and in-hospital treatments). We used a multivariate logistic regression model and, being heparin the only one therapy affecting survival rate, we compared prophylactic LMWH (p-LMWH) and Therapeutic LMWH (T-LMWH) groups. Kaplan Meier curve showed a higher survival probability in the T-LMWH and the difference between the two groups was statistically significant according to the log-rank or Mantel- Haenszel test (p< 0.0001). In a stratified analysis by ventilation type, the subgroup of patients who benefited from therapeutic LMWH was that in non-invasive mechanical ventilation. Using a multivariate analysis and adjusting for the drugs intake, TLMWH was the only therapy impacting on survival (HR 0.293, p <0.001). No fatal bleeding was observed. Therapeutic dose of LMWH in patients admitted to hospital with COVID-19 pneumonia was 70 associated with a decrease risk of intra-hospital mortality.

Authors: Dhanya K. , Chandra Prakash , Anandakrishna Latha , Karuveettil Vineetha
Published: September 2021

Aim:

The aim of this study was to compare the efficacy of NovaMin™ (SHY-NM) and casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) (tooth mousse plus™) on enamel remineralization using DIAGNOdent® and scanning electron microscope (SEM).

Methodology:

Eighty-six natural permanent maxillary first premolars were selected and randomly divided into two groups of 43 each, Group A (NovaMin™) and Group B (CPP-ACPF). All the samples were assessed using DIAGNOdent® (KaVo) at the baseline, after demineralization, and remineralization after 7 days. Two samples were randomly selected from each group after remineralization to evaluate the surface changes using SEM at × 1000 and × 2000.

Results:

The mean value of remineralization was highest for Group A NovaMin™ (6.56 ± 0.93) compared to Group B, CPP-ACPF (tooth mousse plus™) (6.02 ± 1.09). The maximum demineralization to remineralization value within the groups showed that the mean values in Group B CPP-ACPF (7.02 ± 3.02) was higher than Group A NovaMin™ (6.42 ± 2.21). The difference in remineralizing potential between the groups and demineralization to remineralization value in within-group comparison was not found to be statistically significant.

Conclusion:

On comparing Group A NovaMin™ and Group B CPP-ACPF, Group B CPP-ACPF showed a higher amount of remineralization than Group A NovaMin™. From the present study, it can be inferred that both the experimental groups have the potential for remineralization.

Published: September 2021

Objective:

Cancer stem cells (CSCs) belong to a subpopulation of undifferentiated cells present within tumors that have the potential to regenerate, differentiate, maintenance of pluripotency, drug resistance, and tumorigenicity when transplanted into an innate host. These can influence the growth and behavior of these tumors and are used to investigate the initiation, progression, and treatment strategies of laryngeal cancer. Research on CSC science and targeted therapies were hinge on their isolation and/or enrichment procedures. The object of the study is to isolate cancer stem cells from primary laryngeal carcinoma (CSCPLC) by tumor spheres enrichment. We checked the properties of self-renewal, stemness, clonogenicity, and chemotherapeutic resistance.

Materials and Methods:

We performed tumor sphere formation assay (primary, secondary, and tertiary) chemotherapy resistance by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay were performed to evaluate the CSC cells. Immunofluorescence for stem cell markers (CD133+, CD44+) and gene expression of stem cell markers for CD133+, CD44+, OCT4, SOX2, and NANOG was done using the real-time polymerase chain reaction technique.

Results:

We were able to isolated CSC subpopulations from PLC cell lines by the tumor sphere method. These cells exhibited good primary, secondary, and tertiary tumor sphere formation efficiency and also disclosed a resistant index of more than 2. Immunofluorescence for stem cell markers (CD133+ and CD44+) confirms the presence of CSC. There was significantly higher mRNA expression of stem cell markers in CSC enriched subpopulations compared to the parental cell lines.

Conclusion:

We conclude that tumor spheres enrichment is an efficient, economical, and reliable approach for the isolation and characterization of CSC from PLC cell lines. These cells demonstrated the properties of self-renewal, stemness, clonogenicity, and chemotherapeutic resistance.

Comparative Evaluation of Effectiveness of 2% Lignocaine Hydrochloride with Clonidine Hydrochloride versus 2% Lignocaine Hydrochloride with Adrenaline Bitartrate as Local Anesthetic for Adult Patients Undergoing Surgical Extraction of Impacted Mandibular Third Molars
Authors: Gupte Shreyas H. , Kalra Rinku D. , Dcruz Thomson M. , Kamble Sahil , Patnaik Ranjana S.
Published: September 2021

Background and Objectives:

Clonidine is a common additive to local anesthetics for various regional and local nerve blocks. However, its effectiveness in dentistry has not yet been fully explored. Thus, this study was performed to evaluate the quality of anesthesia, vasoconstrictive effects, hemodynamic response, and pain control using a solution of 2% lignocaine hydrochloride with clonidine hydrochloride in comparison with the standard solution of 2% lignocaine hydrochloride and adrenaline bitartrate for pterygomandibular nerve blocks.

Materials and Methods:

A parallel arm, triple-blind randomized controlled study was conducted on 152 patients belonging to ASA-I (American Society of Anesthesiologists) category in the age group of 18-45 years, requiring surgical extraction of impacted mandibular third molars. The patients were divided equally into two groups randomly by computer-generated sequence; Group 1: 2% lignocaine hydrochloride with 1 ml of clonidine hydrochloride (150 μg/ml) and Group 2: 2% lignocaine hydrochloride with adrenaline bitartrate 1: 80,000 (12.5 μg/ml). The variables evaluated were systolic, diastolic, and mean arterial blood pressures, heart rate (HR), blood loss, onset, depth (pain), and duration of anesthesia.

Results:

There was a statistically nonsignificant difference seen between the two groups (P > 0.05) for the onset of anesthesia, pain assessed, and blood loss, whereas a statistically highly significant difference was seen for cardiovascular variables (systolic, diastolic and mean arterial blood pressures, and HR) at various intervals with higher values for Group 2 (P < 0.001) and for the duration of action of local anesthesia (LA), with higher values for Group 1 (P < 0.001).

Conclusions:

Clonidine as an additive to lignocaine has proved to have the onset of action, vasoconstrictive properties, and pain control, equivalent to adrenaline. However, with better stability of hemodynamic variables and prolonged duration of action of LA with clonidine, it can be considered as a better, safer, and more effective additive to lignocaine than adrenaline

Published: September 2021

A solitary median maxillary central incisor (SMMCI) is a rare anomaly that can occur alone or be associated with other systemic abnormalities. Early diagnosis of SMMCI is crucial as it might indicate the presence of an associated congenital or developmental abnormality. The prevalence of live-born children with SMMCI is determined to be 1:50,000 and is more common among females. The purpose of this paper was to report an unusual case of a 9-year-old girl with SMMCI who had no growth deficiency or any other systemic involvement. Since pediatricians and dentists are the first professionals to evaluate an SMMCI's patient in most cases, it is important that they be aware of the possibility of other related systemic problems that require systemic care. Appropriate treatment, diagnosis, and referral should also include neuropediatric evaluation, genetic testing, and craniofacial profile analysis along with multidisciplinary approach.

Authors: Murugan Thamaraiselvan , Inbasekaran Dipika , Murthykumar Karthikeyan
Published: September 2021

Gingival recession predisposes to functional and aesthetic concerns, for which many surgical procedures are available. Among these, till now subepithelial connective graft is considered as the gold standard technique for its higher predictability of achieving recession coverage. However, it does not heal by new attachment, thus many techniques to promote new attachment such as root biomodification are done. This case enumerates the use of Er, Cr: YSGG laser for root biomodification to treat a wide and deep gingival recession defect by subpedicle connective tissue graft. Six months results show better recession coverage inspite of a wide and deeper defect. Thus, Er, Cr: YSGG laser can be an adjunctive tool to enhance the recession coverage.

The primary outcome evaluated complete ablation of the lesions radiologically and the secondary outcome evaluated adverse events (AEs).

Results:

Fifteen studies on 524 patients were included in our analysis. The pooled complete ablation rate was 58.89% (95% confidence interval (CI) = 38.72–77.80, I2 = 91.76%) and 55.99% (95% CI = 44.66–67.05, I2 = 0) in the EUS E and EUS EP groups (P = 0.796), respectively. The pooled AE rates were 13.92% (95% CI = 4.71–26.01, I2 = 83.43%) and 31.62% (95% CI = 3.36–68.95, I2 = 87.9%) in the EUS E and EUS EP groups (P = 0.299), respectively. The most common AE was abdominal pain at 7.27% (95% CI = 1.97–14.6, I2 = 68.2%) and 12.44% (95% CI = 0.00–39.24, I2 = 81.1%) in the EUS E and EUS EP groups (P = 0.583), respectively. Correlation coefficient (r) was -0.719 (P = 0.008) between complete ablation and lesion size.

Conclusion:

Complete ablation rates were comparable among both groups. AE rates were higher in the EUS EP group. Further randomized controlled trials are needed to validate our findings.

Background:

Laparoscopic complete mesocolic excision (CME) with D3 lymph node dissection for the right colon is becoming popular, but still technically challenging. Several articulating laparoscopic instruments had been introduced to reduce technical difficulties; however, those were not practical. This study aimed to report the first clinical experience of using ArtiSential®, a new laparoscopic articulating instrument in laparoscopic complete mesocolic with D3 lymph node dissection for right colon cancer.

Patients and Methods:

This was a retrospective, single-institution, consecutive case study. From October 2018 to March 2020, a total of 33 patients underwent laparoscopic right hemicolectomy using ArtiSential® , a new articulating instrument. We compared the short-term outcomes of patients who underwent surgery using ArtiSential® (AG) to the conventional instrument (CG).

Results:

In total, there were 33 cases in AG and 43 cases in CG. There were no significant differences in operation time (141.0 ± 22.5 vs. 156.0 ± 50.6 min, P = 0.09), mean estimated blood loss (46.8 ± 36.2 vs. 100.8 ± 300.6 ml, P = 0.31) and intra-operative and post-operative complications. However, the number of harvested lymph nodes was higher and the length of hospital stay was shorter in AG than in CG (32.6 ± 12.2 vs. 24.6 ± 7.4, P < 0.01 and 3.0 ± 1.2 vs. 4.1 ± 2.2 days, P = 0.01, respectively).

Conclusions:

Laparoscopic CME with D3 lymph node dissection for right colon cancer using ArtiSential®, the new articulating laparoscopic instrument is safe and technically feasible.
Time-Optimal Coordination Control for the Gear-Shifting Process in Electric-Driven Mechanical Transmission (Dog Clutch) without Impacts
Authors:   Tsinghua University, China, Lu Ziwang , Tian Guangyu ,   Tsinghua University, China
Published: September 2021

Torque interruption and shift jerk are the two main issues that occur during the gear-shifting process of electric-driven mechanical transmission. Herein, a time-optimal coordination control strategy between the the drive motor and the shift motor is proposed to eliminate the impacts between the sleeve and the gear ring. To determine the optimal control law, first, a gear-shifting dynamic model is constructed to capture the drive motor and shift motor dynamics. Next, the time-optimal dual synchronization control for the drive motor and the time-optimal position control for the shift motor are designed. Moreover, a switched control for the shift motor between a bang-off-bang control and a receding horizon control (RHC) law is derived to match the time-optimal dual synchronization control strategy of the drive motor. Finally, two case studies are conducted to validate the bang-off-bang control and RHC. In addition, the method to obtain the appropriate parameters of the drive motor and shift motor is analyzed according to the coordination control method.
Understanding Real-World Variability of Hybrid Electric Vehicle Fuel Economy
Authors:   University of Warwick, UK, McGordon Andrew , Jennings Paul ,   University of Warwick, UK
Published: September 2021

The variability of fuel economy (FE) is of significant importance as that of average FE to realize FE benefits of hybrid electric vehicles (HEVs) consistently by all users in the real world. Over the years, majority of the research has been focused on improving average FE overlooking the variability. Although in recent years few studies have been focused on the reduction of FE variability, no study has been concentrated to understand why certain design has lower FE variability as that of others. This article provides a detailed analysis to decipher the reasons for the FE variability in the real world. This study considered the optimum designs based on two established design optimization methodologies considering Toyota Prius non-plug-in hybrid as a base vehicle. This study analyses the impacts of the parameters of driving patterns and the operation of powertrains on FE variability. The study explains that comparatively bigger internal combustion engine (ICE) in combination with the optimum sizes of generator motor and battery could lead to lower FE variability in the real world due to lesser time of operation of ICE to charge the battery.
John’s prologue: Christological and doxological significance for the Johannine narrative
Authors: Hahn Nathan , van Eck Ernest
Published: September 2021

This article presents a literary exegetical analysis of the prologue (John 1:1-18) of the Johannine narrative with special attention to the author’s (narrator’s) point of view. The author sets the tone of his gospel and writes with literary beauty while showing his theological points of view that will be seen throughout his narrative to follow. He presents Jesus as the eternal λόγος of God, and thus provides a unique point of view toward the Son of God of the Father who exists from eternity past with God the Father. Merely by studying, reflecting on, and remembering the Gospel’s prologue, the reader can understand and relate to the Christological and doxological significance of the Johannine narrative.
Cryptanalysis of the SoDark Cipher for HF Radio Automatic Link Establishment
Authors: Dansarie Marcus
Published: September 2021

The SoDark cipher is used to protect transmitted frames in the second and third generation automatic link establishment (ALE) standards for high frequency (HF) radios. The cipher is primarily meant to prevent unauthorized linking and attacks on the availability of HF radio networks. This paper represents the first known security analysis of the cipher used by the second generation ALE protocol—the de facto world standard—and presents a related-tweak attack on the full eight round version of the algorithm. Under certain conditions, collisions of intermediate states several rounds into the cipher can be detected from the ciphertext with high probability. This enables testing against the intermediate states using only parts of the key. The best attack is a chosen-ciphertext attack which can recover the secret key in about an hour with 100% probability, using 29 chosen ciphertexts.
Improved guess-and-determine and distinguishing attacks on SNOW-V
Authors: Yang Jing , Johansson Thomas , Maximov Alexander
Published: September 2021

In this paper, we investigate the security of SNOW-V, demonstrating two guess-and-determine (GnD) attacks against the full version with complexities 2384 and 2378, respectively, and one distinguishing attack against a reduced variant with complexity 2303. Our GnD attacks use enumeration with recursion to explore valid guessing paths, and try to truncate as many invalid guessing paths as possible at early stages of the recursion by carefully designing the order of guessing. In our first GnD attack, we guess three 128-bit state variables, determine the remaining four according to four consecutive keystream words. We finally use the next three keystream words to verify the correct guess. The second GnD attack is similar but exploits one more keystream word as side information helping to truncate more guessing paths. Our distinguishing attack targets a reduced variant where 32-bit adders are replaced with exclusive-OR operations. The samples can be collected from short keystream sequences under different (key, IV) pairs. These attacks do not threaten SNOW-V, but provide more in-depth details for understanding its security and give new ideas for cryptanalysis of other ciphers.
Primavera, invierno, primavera. Los ciclos de luchas feministas y la izquierda uruguaya
Authors: De Giorgi Ana Laura
Published: September 2021

La relación entre la izquierda y el feminismo ha sido de encuentros y desencuentros. Este diálogo  entrecortado también ha impactado en los estudios sobre uno y otro proyecto emancipatorio. Los estudios sobre la izquierda se han centrado en múltiples aspectos pero prácticamente no han considerado las ideas y prácticas feministas que emergieron en el seno de la izquierda. Por su parte, los estudios sobre los  feminismos han tomado la misma distancia: se han estudiado organizaciones e ideas como si no tuvieran vínculo alguno con la izquierda. Este artículo tiene como principal objetivo comprender al feminismo en esa relación, analizando el caso uruguayo donde resulta imprescindible considerar ambos proyectos de forma conjunta, principalmente para los 80, pero también en la actualidad.
Las bolcheviques. Izquierda partidaria y movimiento de mujeres en la Argentina reciente
Authors: Casola Natalia
Published: September 2021

En los últimos años el interés por estudiar la historia del movimiento de mujeres y del feminismo en Argentina ha registrado un sensible crecimiento. Si bien se ha avanzado en el conocimiento sobre la experiencia de diversos colectivos, agrupamientos y demandas específicas, poco o nada se ha escrito sobre el papel de los partidos de izquierda en esos procesos, a pesar de que han estado presentes en la mayoría de las luchas. Este artículo se propone comenzar a resolver esa vacancia. Para ello propone una revisión panorámica acerca de las posiciones y formas de vinculación de cuatro partidos de izquierda (PC, PCR, MAS y PO) con el movimiento de mujeres.
