Implicit expectation modulates multisensory perception
Authors: Zeljko Mick , Grove Philip M. , Kritikos Ada 
Published: March 2022

AbstractStimulus statistics can induce expectations that in turn can influence multisensory perception. In three experiments, we manipulate perceptual history by biasing stimulus statistics and examined the effect of implicit expectations on the perceptual resolution of a bistable visual stimulus that is modulated by sound. First, we found a general effect of expectation such that responses were biased in line with the biased statistics and interpret this as a bias towards an implicitly expected outcome. Second, expectation did not influence the perception of all types of stimuli. In both Experiment 1 and Experiment 2, integrated audio-visual stimuli were affected by expectation but visual-only and unintegrated audio-visual stimuli were not. In Experiment 3 we examined the sensory versus interpretational effects of expectation and found that contrary to our predictions, an expectation of audio-visually integrated stimuli was associated with impaired multisensory integration compared to visual-only or unintegrated audio-visual stimuli. Our findings suggest that perceptual experience implicitly creates expectations that influence multisensory perception, which appear to be about perceptual outcomes rather than sensory stimuli. Finally, in the case of resolving perceptual ambiguity, the expectation effect is an effect on cognitive rather than sensory processes.

Published: March 2022

The extensive forests over limestone of the Samar Island Natural Park (SINP) on Samar Island, Philippines harbour a rich variety of unique species. In this contribution, we describe and illustrate a new Loranthaceous mistletoe, endemic to Samar Island named Decaisnina tomentosa, representing the 12th member of the genus reported to the Philippines.
This new species is similar to D. confertiflora (Merr.) Barlow with respect to the presence of shortly and densely off-white tomentose inflorescence and 6-merous flowers. However, it is unique amongst congeners in having tomentose and partially fused bracteoles which cover almost or entirely the ovary of individual flowers in the triads. To date, D. tomentosa seems to be restricted to the SINP and is only known from a handful of individuals. More studies are needed to properly assess the demography, host range, conservation status and phylogenetic position of this distinctive species of mistletoe.
Correlation between cognitive abilities and social functioning in patients with multiple sclerosis
Authors: Genov Krasimir , Dimitrova Maria 
Published: March 2022

Introduction: Cognitive impairment has been found in all stages and subtypes of multiple sclerosis (MS). It has a broad negative impact on the lives of people with MS independent of physical symptoms. Perhaps the most severe and far-reaching effect is unemployment, which results in extensive personal, social, and financial costs. Cognition has been linked to unemployment in many countries and shown to mediate the effects of disability on employment status.
Aim: The primary aim of this study was to assess social functioning in the context of activities of daily living and employment in patients with MS and to find a correlation between them and cognitive performance in these patients. The secondary aim was to find an association between employment and factors such as demography, emotional factors, and disease progression.&nbsp;
Materials and methods: The research included a study group of 100 patients with MS meeting the defined exclusion and inclusion criteria, and a control group of 40 healthy subjects. Disability was assessed with the Expanded Disability Status Scale (EDSS). The employment status was appraised in interviews with the subjects. The patients were divided into two groups: employed (working on a full-time or part-time job) and unemployed (not-working). The study aimed to assess the cognitive performance of all subjects. We examined cognitive domains such as short-term memory, psychomotor speed, and executive functions with a battery of neuropsychological tests.
Results: We found a connection between performance on neuropsychological tests and employment and engagement in activities of daily living. Another main conclusion of our study is that unemployed are older patients with longer duration of disease. They have excessive fatigue and unsatisfied results and impairment of memory functions. As to the reasons we found in our study for losing a job, some identified factors are the presence of excessive fatigue (44%), movement disorders (41%), cognitive impairment (30%), pain (15%), dizziness (15%), dexterity (11%), emotional disorders, bowel and bladder disorders (7%), visual deficit (7%), and heat sensitivity (4%).
Conclusions: Unemployed patients have severe depressive symptoms.

Aim: Infantile hemangiomas are the most common benign vascular tumours in infants. In this study, we aimed to evaluate the effectiveness of propranolol therapy in patients with infantile hemangioma.
Materials and methods: This study included patients with infantile hemangiomas in the age range of 0 to 24 months who received propranolol therapy between September 2015 and 2019. Hemangioma activity score, ultrasonography imaging and photographic evaluations were performed before and at 6 months of treatment. Parental satisfaction with the results of treatment was recorded.
Results: Our study included 85 patients with infantile hemangioma requiring treatment. Twenty patients were boys and 65 were girls. The mean age at starting treatment was 7.2&plusmn;5.9 months (median: 5.0). While the average lesion area measured by ultrasonography&nbsp;before treatment was 209.7&plusmn;207.5 mm2, it reduced to 105.1&plusmn;145.7 mm2 (p<0.001) after treatment. Similarly, while the mean hemangioma activity score was 3.8&plusmn;0.9 before treatment, it decreased significantly to 1.3&plusmn;0.8 after the treatment (p<0.001). A noticeable improvement in photographic evaluation with the treatment was observed in infantile hemangiomas of the patients and 82% of the families were satisfied with the results of the treatment.
Conclusions: The results of the study suggested that propranolol therapy used in the treatment of infantile hemangioma is an effective treatment option according to the photographic comparison, ultrasonography data, and hemangioma activity score evaluations.

Introduction: Circadian variations in biological rhythms affect the pharmacological properties of many anaesthetic agents, suggesting circadian patterns of local anaesthetics&rsquo; activity in labour pain analgesia, with important differences among diurnal and nocturnal phases.
Aim: We examined whether a rhythmic variation of the effect of intrathecal mixture of levobupivacaine and fentanyl exists throughout the day period regarding caesarean sections.&nbsp;
Materials and methods: Eighty parturients presented for caesarean section, both urgent and/or elective, were assigned to five equal groups (A, B, C, D, and E) according to the time-point of the intrathecal drug administration. The same levobupivacaine and fentanyl dose was given to all patients. Pinprick or cold test, the four-point modified Bromage scale (0-3), and the numerical scale (NRS 0-10) were used respectively for the assessment of sensory and motor blockade, and post-anaesthetic pain. The duration of sensory and motor blockade, analgesia duration and pain score at first analgesic request were recorded.
Results: Statistically significant differences were found among the studied groups in the duration of motor and sensory blockade and pain score at first postoperative analgesic request. Prolonged duration of motor blockade in groups A, B and C (p<0.001) and prolonged duration of sensory blockade and analgesia in groups A, B (p<0.001) were observed. Higher pain scores at first postoperative analgesic request were recorded in group &Epsilon; (p<0.001).&nbsp;
Conclusions: The present study highlights the significant effects of circadian rhythm on the efficacy of a mixture of local anaesthetics, levobupivacaine and fentanyl, during caesarean delivery.

Published: March 2022

The manual broth micro-dilution (mBMD) is the recommended reference method for colistin minimum inhibitory concentration determination; however, it is not as readily available in South Africa as the Vitek®2. This retrospective study compared the performance of Vitek®2 against mBMD in determining the colistin minimum inhibitory concentration of 337 extensively drug-resistant Acinetobacter baumannii complex isolates. Vitek®2 yielded a categorical agreement of 89%, an essential agreement of 56%, a major error rate of 8% and a very major error rate of 55%. The Vitek®2 is not an alternative to mBMD for colistin susceptibility testing.

Authors: Ariwibowo Agung , Irsyad Muhammad , Amrul Amrul 
Published: March 2022

The use of air conditioning affects energy consumption. Thermal load is a big factor that affects energy consumption by air conditioners. For this reason, the thermal load of a room needs to be reduced. One strategy to reduce the room's thermal load is the use of phase change materials (PCM). Coconut oil is a PCM that has a freezing temperature in the range of 21.30 – 21.73 oC which will be investigated in this study. The test was carried out with three room models; without PCM, with PCM partition, and PCM partitioned with night air. Each room model carried out 3 variations of air temperature, as well as 4 variations of the heater. The results showed that the use of coconut oil PCM as a room partition can help reduce the room temperature to 2oC below the AC temperature with a decrease in the use of electrical energy reaching 400 Watts.

PHONEMIC TRANSCRIPTION ERROR ANALYSIS OF UNDERGRADUATE ENGLISH LANGUAGE STUDENTS IN SOUTHWESTERN NIGERIA
Authors: Bamigbade Waheed Adeyimika , Raji Zainab Olamide 
Published: March 2022

This paper investigates phonemic transcription errors of L2 learners of English, using the undergraduate students of the Department of English Language, Obafemi Awolowo University, Ile-Ife, Osun State, Nigeria, as case study and compares performance across levels and phonemes. Twenty (20) randomly selected respondents from each of the four undergraduate levels - a total of eighty (80) participants, were asked to do a phonemic transcription of a researcher-crafted text of two sentences comprising all the 44 English phonemes and one purposively infused triphthong. The Daniel Jones’s (2011) Cambridge Pronouncing Dictionary was used as standard in grading the test. The transcriptions were then closely studied, categorized, and analysed. Findings show that L2 learners and users of English committed errors of Substitution (259, 41%), Addition (87, 13%), Replacement (66, 10%), and Omission of Sounds (33, 05%) out of the 675 transcription errors identified. None (00%) out of the 80 participants was able to transcribe the triphthong sound correctly, amounting to 12% of the total errors; while three specific transcription rules, namely the rule of realizing strong vowel sounds in function words as schwa /ə/ which was abandoned in 150 instances (22% of total errors), mostly in ‘and’ and ‘to’; the rule of not realizing vowels as schwa in content words which they applied indiscriminately; and the rule of double slashes inserted at the beginning and the end of a transcribed sentence which none of them observed. The study also finds 60% of vowel errors and 40% of consonant errors, while out of all 44 phonemes, all respondents got only nine (9) consonant sounds correctly, indicating that respondents face greater difficulty with the English vowel sounds. It is concluded that these errors are due mostly to interference and non-adherence to rules symptomized in incorrect articulation and erroneous transcription. Finally, this study emphasizes the crucial role of error analysis in L2 language learning and development as it provides useful insights into the nature of errors, and points at implications for curriculum improvement, pragmatic methodologies and technology application in language teaching and learning.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0918/a.php" alt="Hit counter" /></p>
