Published: September 2023

The present study explored the simultaneous role of various individual, parental, and school factors in students’ test anxiety. Participants included 339 parent-child dyads (N = 678) from 13 elementary and high schools of the Quebec province, Canada. Both dyad members provided data through self-report validated scales at two timepoints (T1 = final year examinations in May-June 2019, T2 = normal school curriculum period, October-November 2019). Results of multilevel linear mixed-effect models revealed that negative stress mindsets, self-oriented and socially prescribed perfectionism, and low autonomous motivation significantly predicted students’ test anxiety months later. Interestingly, after accounting for these individual variables, parents’ trait anxiety, school type and school level predicted a small yet unique part of the variance in students’ test anxiety. However, controlled motivation, parental practices, parental perceived threat in the environment and socioeconomic status did not significantly predict test anxiety once all the other factors considered. Results did not vary significantly across students’ gender. In considering individual, parental and school factors in combination, the current study provides important insights regarding both their relative contribution and their additive relations with students’ test anxiety. In doing so, our work points out possible contextual targets for interventions to reduce students’ test anxiety in school.
Classroom Emotions in Civic Education: A Multilevel Approach to Antecedents and Effects

Published: September 2023

Classroom emotions are major predictors of student learning and academic outcomes. Emotions might be of particular significance in civic education, where oftentimes highly controversial and heated debates take place. We examined antecedents and effects of classroom emotions in civic education through the lens of the control-value theory, where emotions are categorized in terms of valence (positive/negative) and arousal (activating/deactivating). Specifically, we investigated the classroom climate during discussions of political and social issues as an antecedent of students’ enjoyment, shame, anxiety, and boredom, in addition to a possible mediation effect of these emotions on political knowledge and participation as core outcomes in this domain. We tested our assumptions based on data from 1,117 students at vocational schools (grades 10–13). Multilevel structural equation modeling revealed different results based on the valence of emotions, showing a positive relation between an open classroom climate and enjoyment and negative relations with anxiety and boredom. No support was provided for the relation to shame. Enjoyment related positively, and all negative emotions (shame, anxiety, boredom) negatively to achievement on the knowledge test. In terms of arousal, all activating emotions (enjoyment, shame, anxiety) related positively to intended political participation. Furthermore, enjoyment mediated the association between classroom climate and intended political participation at the student level. Thus, this study strongly supports the theoretical assumptions of the control-value theory. Pedagogically, the results imply that fostering a classroom context that is open to diverse opinions can prevent the experience of negative emotions and increase students’ experience of enjoyment.

The authors have attempted to design and verify a model of comprehensive (medical, social and psychological) prognosis in cardiovascular disease, which would cover aspects of patients’ illness, treatment and life functioning. A multidisciplinary set of methods was used to realise the aim. The study included 437 patients suffering from coronary heart disease or chronic heart failure, both of ischaemic and non-ischaemic etiology, who were referred for cardiovascular surgery, and who had undergone surgical intervention.

Part II of the article presents the results of the 3 final stages of the study. These are the following: 5) The studied indicators were divided into the following subgroups: “Current state factors” (reflecting the patients’ current psychological state, characterising their cognitive and emotional-affective spheres) and “Baseline factors” (reflecting relatively stable characteristics of the disease, socio-behavioural and personal features of the patients). 6) A new factor analysis was performed, resulting in 11 secondary factors: 5 in the group of “Current state factors” (“Psychological well-being”, “Quality of life in the face of cardiac disease”, “Reduced non-verbal cognitive functions due to anxiety”, “Positive mood and cognitive state”, “State of mnestic function”) and 6 in the group of “Baseline factors” (“Non-constructive behaviour in the face of disease”, “Occupational motives and severity of cardiovascular disease”, “Psychosocial risk factors for coronary heart disease”, “Patient motivation, tension and severity of chronic heart failure”, “Social support and resilience”, “Adherent behaviour and rational thinking”). 7) We used mathematical modelling and a neural network to determine the prognostic value of the above factors and to construct a systematic prediction model that will be capable of predicting the value of all “Current state factors” at any given time (days after surgery) with an accuracy of up to 80%. In the future, we plan to design a model for the “Baseline factors”.

The identification of prognostically relevant patients’ characteristics at the stage of preparation for cardiac surgery can help to optimise psychological help for the patient during this time and individualise the postoperative rehabilitation programme.
Cartooning in Medical Illustration
Authors: Littleton J. T.
Published: September 2023

The total development of a research project in any scientific area may well be divided into two phases. A working hypothesis stimulates the formation of an experimental approach, and the accumulation of data which is then analyzed and interpreted with the final development of a firm conclusion. The second phase of the project involves the transmission of this information to the scientific public. For practical purposes, the latter may often be more important than the former. Unless the material is properly transmitted to and thoroughly understood by a reading and listening audience, the efforts of the investigator will be in vain. Visual aides in the form of photographs, charts, etc. are very helpful in illustrating the specific data, however, the expression of a general hypothesis sometimes becomes quite difficult. The use of a cleverly designed and professionally executed cartoon can often significantly simplify this problem.

Features of the pigment complex of winter wheat plants depending on the method of fertilisation
Authors: Bilousova Z. , Klipakova Y. , Keneva V.
Published: September 2023

To maximise the yield of winter wheat, it is necessary to further optimise modern cultivation technologies to adapt them to changing environmental conditions. One of the aspects of plant adaptation to unfavourable abiotic factors is the active functioning of the photosynthetic apparatus, which depends on the number of nutrients applied. This paper investigates the effect of fertilisation on the state of the pigment complex of winter wheat plants in the Southern Steppe of Ukraine. Two varieties of winter wheat were selected for the study: Shestopalivka and Mason. The scheme of the experiment included the application of fertilisers during sowing (К0; К12) and foliar processing with various tank mixtures (urea; urea + magnesium sulphate; urea + magnesium sulphate + potassium monophosphate). The pigment content was determined by grinding fresh leaves of winter wheat with further addition of a solvent in the form of acetone. The pigments were measured using a spectrophotometer. The results of the studies showed that before foliar fertilisation, the content of chlorophyll a and carotenoids was higher in the leaves of plants of the Shestopalivka variety. At the same time, the content of chlorophyll b was higher for Mason plants by 17%, which may be a consequence of the adaptation of plants of this variety to a lack of light. A decrease in the pigment content in the leaves of plants of all experimental variants caused by the active growth of the photosynthesising surface and a decrease in the total dry matter mass was observed on day 3 after the foliar fertilisation. There was no significant difference between varieties in the content of photosynthetic pigments during this period. On the 10th day after foliar spraying, an increase in the content of chlorophyll a and b was observed for both studied varieties, which may be the result of the adaptation of the photosynthetic apparatus of winter wheat plants to lighting conditions. Foliar fertilisation of winter wheat plants with a tank mixture of urea with magnesium sulphate and potassium monophosphate contributed to a further increase in the content of chlorophyll a by 12-23% and chlorophyll b by 5-37%, depending on the variety compared to the control. The results of the conducted research indicate the high efficiency of the complex application of nitrogen-phosphorus-potassium fertilisers for foliar spraying of winter wheat plants at the stage of BBCH 31 both on the background of pre-sowing potassium fertilizers and without it

Middle Holocene Oyster Shells and the Shifting Role of History in Ecological Restoration: How a Dynamic Past Informs Shellfish Ecosystem Reconstruction at an Australian Urban Estuary
Authors: Christensen Joseph , Martin Daniel Jan , Bossie Andrew , Valesini Fiona
Published: September 2023

At Western Australia's Swan-Canning Estuary, extensive subfossil shellfish assemblages of Middle Holocene origin were largely destroyed through dredging for cement production in the first half of the twentieth century. This case-study of an extractive industry driving shellfish ecosystem decline builds on existing historical studies of commercial over-harvesting of oysters, and historical and paleo-ecological investigations of sustainable, long-term indigenous oyster harvests, presenting an important new perspective on global shellfish ecosystem decline and the enduring cultural value of shellfish resources by revealing processes of cross-cultural knowledge transfer, unfolding environmental understanding and extensive environmental change across Western Australia's post-European settlement history. We explore these histories in detail for the first time, before considering their relevance to a shellfish ecosystem reconstruction initiative currently underway at this major Australian urban estuary.

ADSORPTION OF Cu (II) IONS FROM WASHING SOLUTIONS OF TAILINGS BY DOWEX MAC-3 H+ SORBENT
Authors:   M.Nagiev Institute of Catalysis and Inorganic Chemistry, Ministry of Science and Education  of the Republic of Azerbaijan, Heydarov A.A.
Published: September 2023

In this article, the experimental results of the adsorption of Cu2+ ion with Dowex Mac-3H+, a cation exchange resin with weak acid character, were investigated. Factors affecting the adsorption of copper ions from sulfated solutions: the initial concentration of Cu2+ ion, the dose amount of the adsorbent, the concentration-time, and the pH of the solution were studied. The obtained results showed that Dowex Mac-3H+ resin shows a high volume capacity (322.6 mg/g) in the separation of Cu2+ ions from sulfated solutions. At the initial concentration of 0.5 g/l, for 4 hours, when 0.2 g of sorbent was taken, at pH 6, at room temperature, the adsorption rate of Cu2+ ions was maximal (98%). In the first 1 hour, sorption occurs at a high rate, and increasing the contact time does not affect the process much. Due to the increase in the concentration of OH- ions at higher pH values, it is observed that the Cu2+ ion changes to the Cu(OH)2 precipitate form. The values of the obtained experimental results fully correspond to the Langmuir and Freundlich isotherms. It can be seen from the adsorption isotherms of the Langmuir and Freundlich model that the adsorption of Cu2+ ions on the resin occurs according to the chemisorption mechanism

Planners navigating platform urbanism
Authors: Klein Leorah
Published: September 2023

This research reflects on the role of an urban planner in an increasingly connected, data-driven urban context. The rise of urban-focused digital platforms has positioned 

municipalities as key customers for profit-driven organizations selling data and analytical tools to enhance quality of life in cities. This research focuses on ten urban-focused platforms and assesses their market positioning (promised value) and real-life application (actualized value), uncovering benefits and challenges associated with their use. The analysis explores how platforms can influence planning decisions, and a planner’s role in

influencing the use of platforms. Findings suggest that planners have a critical role to play in determining each platform’s ability to provide real value within each city’s unique context. Recommendations highlight considerations for planners, specifically: the limits of platform data, potential trade-offs, and alignment with current state operations. An acute understanding of these dynamics will support planners in navigating platform urbanism while upholding the public interest.

Key words: Platform Urbanism; civic technology; urban planning innovation.

Published: September 2023

INTRODUCTION: The chronic effects of regular exposure to high acceleration levels (G-force) on the neuro-cardiovascular system are unclear. We compared the mean arterial pressure (MAP) and cardiac autonomic modulation between nonpilots (NP) vs. military fighter (FP) and transport
(TP) pilots. Additionally, we correlated the cardiac autonomic indices with the cardiorespiratory fitness and flight experience of FP.METHODS: A total of 21 FP, 8 TP, and 20 NP performed a tilt test (TT), during which beat-to-beat blood pressure and heart rate were recorded.RESULTS:
No difference was detected between groups for changes in MAP and heart rate variability indices during the TT. However, the analysis of areas under the curves showed a greater increase in MAP in FP vs. TP and NP. Conversely, there was a greater decrease in indices reflecting vagal modulation
in TP vs. FP and NP (rMSSD, pNN50, and SDNN), and a greater increase in heart rate and sympathovagal balance in TP vs. other groups (LF/HF). The maximal oxygen uptake was strongly correlated with the vagal reserve in FP (r = −0.74). Moreover, the total flying hours of FP were positively
correlated with resting HFnu (r = 0.47) and inversely correlated with resting LFnu (r = −0.55) and LF/HF (r = −0.46).CONCLUSION: FP had a higher pressor response to TT than TP and NP. Vagal withdrawal and sympathovagal increase induced by TT in FP were similar vs. NP
and attenuated vs. TP. Greater cardiorespiratory fitness and accumulated flying hours in FP seemed to favor lower sympathetic and greater vagal modulation at rest.dos Santos Rangel MV, de Sá GB, Farinatti P, Borges JP. Neuro-cardiovascular responses to sympathetic stimulation

Published: September 2023

BACKGROUND: Many current cell phone (mobile phone, smartphone) batteries are lithium-ion. These batteries can overheat and catch fire under certain conditions. If it happens during a flight or air activity, this might compromise aviation safety. We report a case of a man whose
phone caught fire during a parachute jump.CASE REPORT: The individual, a member of Police Special Forces, is required to regularly perform parachute jumps. During the incident flight, the man had a cell phone in a pocket that ignited during the jump. He was able to land and then
extract the phone with burns requiring acute medical care and later a skin graft.DISCUSSION: This is a cautionary tale of lithium-ion batteries in flight. Many other situations could also occur with these batteries. There is little medical documentation of the risk of fire with
lithium-ion batteries causing injuries during flight operations. To reduce the risk of fire, the devices should be powered down and phones should not be worn directly touching the skin. Damaged devices are more prone to overheating.des Robert V, Saint-Jean L, Corcostegui S-P, Romary

Published: September 2023

INTRODUCTION: Fatigue is a major contributor to aviation accidents. Sufficient sleep may be difficult to achieve under operational conditions in military aviation. Countermeasures include caffeine, however, studies evaluating its effects often do not represent daily practice
with regular caffeine consumption. This study aims to establish the effect of caffeine on psychomotor performance in a realistic scenario (i.e., after a limited period of extended wakefulness).METHODS: This randomized, double-blind, crossover, placebo-controlled trial included 30
aeromedically fit subjects. On trial days, subjects followed their normal routine till 17:00, after which caffeine intake was stopped. At midnight, subjects were given 300 mg of caffeine or placebo and performed the Psychomotor Vigilance Test, Vigilance and Tracking Test, and the Stanford
Sleepiness Scale hourly up to 04:00 and again at 06:00 and 08:00. Four blood samples were collected. Statistical analyses included repeated-measures ANOVA or Friedman tests, marginal models, and Wilcoxon Signed Rank tests.RESULTS: Median time awake at midnight was 17 h (IQR
16.5–17.5 h). Performance decreased significantly less during the night in the caffeine condition versus placebo. Neither habitual intake nor daytime caffeine consumption affected this. No statistically significant correlation was identified between blood concentrations of caffeine
and performance.DISCUSSION: A single dose of 300 mg of caffeine has beneficial effects on performance during the night in a realistic scenario for military aviation. Daytime caffeine consumption does not affect the effects of caffeine at night. These findings could be relevant
for all industries in which optimal performance is required during nighttime after a limited period of extended wakefulness.Wingelaar-Jagt YQ, Wingelaar TT, de Vrijer L, Riedel WJ, Ramaekers JG. Daily caffeine intake and the effect of caffeine on pilots’ performance after extended

Published: September 2023

Skin is the largest organ in humans, it functions as the outermost protector of the organs inside. Therefore, the skin is often attacked by various diseases, especially cancer. Skin cancer is divided into two, namely benign and malignant. Malignant has the potential to spread and increase the risk of death. Skin cancer detection traditionally involves time-consuming laboratory tests to determine malignancy or benignity. Therefore, there is a demand for computer-assisted diagnosis through image analysis to expedite disease identification and classification. This study proposes to use the K-nearest neighbor (KNN) classifier and Gray Level Co-occurrence Matrix (GLCM) to classify these two types of skin cancer. Apart from that, the average filter is also used for preprocessing. The analysis was carried out comprehensively by carrying out 480 experiments on the ISIC dataset. Dataset variations were also carried out using random sampling techniques to test on smaller datasets, where experiments were carried out on 3297, 1649, 825, and 210 images. Several KNN parameters, namely the number of neighbors (k)=1 and distance (d)=1 to 3 were tested at angles 0, 45, 90, and 135. Maximum accuracy results were 79.24%, 79.39%, 83.63%, and 100% for respectively 3297, 1649, 825, and 210. These findings show that the KNN method is more effective in working on smaller datasets, besides that the use of the average filter also has a significant contribution in increasing the accuracy.
Corpus Linguistic Tools for Historical Semantics in Arabic
Authors: Ismail Omaima
Published: September 2023

In this paper, we present a set of corpus linguistic tools for conducting historical semantic research in the Arabic language. We compiled a Historical Arabic Corpus (HAC) that spans more than 1500 years of continuous language use. With techniques from the field of Natural Language Processing (NLP), the tools we presented here have been used to create the HAC and to explore lexical semantic change. The development of these tools is aimed at offering a catalyst to the ambitions goal of compiling an Arabic dictionary on historical principles. HAC and the tools can also be used for conducting research in a variety of areas of linguistics. .
The Directionality of Agree: A Case from Number and Gender Agreement in Standard Arabic
Authors: Nayef Al-Aqarbeh Rania
Published: September 2023

This paper argues for the necessity of a reversed upward Agree. There are three perspectives on the directionality of Agree. Agree conventionally operates downwards with the probe searching for a matching goal that is structurally lower (Chomsky 2000). A reversed upward Agree is also proposed (Zeijlstra 2012). The third perspective involves a parametric variation of Agree whereby Agree can operate either way (Baker 2011). We investigate number and gender agreement in Standard Arabic (SA) because they are independently sensitive to the configuration in which agreement operates. We compare the number and gender agreement patterns of verbal to non-verbal predicates with subjects in different word order alternations. We advocate a unidirectional upward Agree to account for agreement patterns in SA. W argue that while the gender feature of the probe is valued once the goal is structurally higher than the probe; the valuation of the number feature is delayed till the spell-out on the condition that the goal c-commands the probe; otherwise, a default singular value is assigned..
Relationship between anatomical characteristics of pulmonary veins and atrial fibrillation recurrence after radiofrequency catheter ablation: a systematic review and meta-analysis
Authors: Qi Dan , Zhang Jianjun
Published: September 2023

Background

The aim of the current study was to investigate the potential relationship between anatomical characteristics of pulmonary veins (PVs) and atrial fibrillation recurrence (AFR) following radiofrequency catheter ablation (RFCA), specifically focusing on PV diameter and cross-sectional orifices index (CSOA). The analysis was based on a comprehensive review of currently available literature, providing valuable insights for the prevention and treatment of AFR.

Methods

Data was collected from five databases, including PubMed, MEDLINE, EMBASE, and Cochrane, spanning the period from 2004 to October 2022. The search strategy utilized Medical Subject Headings (MeSH) terms related to PV diameter, PV size, PV anatomy, and AFR. Indicators of PV diameter and CSOA from the included studies were collected and analyzed, with Weight mean difference (WMD) and 95% confidence intervals (CIs) representing continuous variables.

Results

The meta-analysis included six studies. The results revealed that patients with AFR had a significant larger mean PV diameter compared to those without AFR (MD 0.33; 95% CI: 0.01, 0.66; P = 0.04; I2 = 33.80%). In a meta-analysis of two studies involving a total of 715 participants, we compared the diameters of the left superior pulmonary vein (LSPV), left inferior pulmonary vein (LIPV), right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV) between patients with AFR and patients without AFR. The results showed that there were no statistically significant differences between the two groups in any of the four data items (all P > 0.05). Additionally, the pooled estimate revealed that LSPV-CSOA, LIPV-COSA, RSPV-COSA, and RIPV-CSOA were greater in the AFR group compared to the non-AFR group, but the differences were not statistically significant (all P > 0.05).

Conclusion

We found evidence supporting the notion that the PV diameter of patients who experienced AFR after RFCA was significantly larger than that of patients without AFR. The findings suggested that the PV diameter could serve as a potential predictor of the risk of AFR following RFCA.

Published: September 2023

Background

Abnormal interstitial fluid accumulation remains the major cause for patients with heart failure (HF) to endure a myriad of distressing symptoms and a decline in their health-related quality of life (HRQoL). The lymphatic system is essential in regulating fluid balance within the interstitial compartment and has recently been recognized as an important target for the prevention and mitigation of congestion. This study aimed to investigate the effects of exercises in activating lymphatic system on symptom distress and HRQoL among patients with HF.

Methods and results

This was a pre-determined, secondary analysis of the TOLF-HF [The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF)] study, a two-arm pilot randomized controlled trial evaluating the preliminary effects of the lymphatic exercise intervention in enhancing interstitial decongestion among patients with HF. Participants were randomized to receive either a four-week TOLF-HF program in addition to standard care or standard care alone. The Chinese version of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was employed to measure symptom distress and HRQoL before and after the intervention. Data analyses included descriptive statistics, the independent sample t-test, Pearson’s chi-square test, the Mann-Whitney U test, and covariance analysis. Of the 66 patients enrolled, 60 completed the study. The study results exhibited that the TOLF-HF intervention were effective in alleviating both physical and psychological symptom distress. The intervention group yielded significantly lower MLHFQ total scores in comparison to the control group. The odd ratio of achieving meaningful improvement in HRQoL in TOLF-HF group was 2.157 times higher than those in the control group.

Conclusions

The TOLF-HF program focusing on activating lymphatic system was effective in alleviating physical and psychological symptom distress as well as improving HRQoL for patients with HF. The tolerability, feasibility, and effectiveness of the TOLF-HF intervention make it a promising intervention for patients to manage HF.
