A Study on the Relationship Between Preservice STEM Teachers’ Beliefs About Migrant Students and Teachers’ Roles in Chinese Urban Schools

The survival and development of migrant students in urban areas were always the focus of all sectors of society. Science, technology, engineering, and mathematics (STEM) subjects are most likely to cause learning difficulties for migrant students, and the beliefs of STEM teachers about migrant students and their role closely affect classroom teaching and after-school support and tutoring. This study focuses on 268 STEM-oriented preservice teachers majoring in elementary education in a normal university in Beijing, China. A questionnaire investigation has been conducted on their beliefs about migrant students’ and teachers’ role in urban elementary schools with metaphor method. The results show that there are significant differences among all the preservice STEM teachers at grade levels, and most of them hold the reality of development and the possibility of development beliefs about migrant students, and the facilitating orientation beliefs about teachers’ role as well. Grade factors are influenced by their curriculum, and beliefs about migrant students show an excessive trend from existence orientation to development orientation with the increasing grade levels. There is a significant correlation between beliefs about migrant students’ and teachers’ role, and preservice teachers with the reality of development beliefs about students are more inclined to the facilitating orientation beliefs about teachers’ role.
MOLECULAR SEQUANCING AND PHYLOGENIC ANALYSIS TO VIRULENCE nmuc-1 GENE IN VISCERAL LARVAE MIGRANCE

Toxocariasis is a zoonotic parasitic disease caused by Toxocara canis infected egg. Larval stage of this parasite has ability to migrate through intestinal wall and invade all body organs causing a visceral larvae migrant (VLM) syndrome. Diagnosis of VLM is problematic; there were no accurate laboratory test that reveals the presence of larvae infection in paratenic hosts (human, ruminants or poultry). The eggs were isolated from adult T. canis uteri and cultured in 0.2M H2S04 solution for embryonation, mice were experimentally infected with emberyonated eggs. Many hisopathological changes detected in heart and kidney tissues of infected mice but it could not detected encysted larvae compared with molecular detection which confirmed infection within first three day post infection in tissue with accurate diagnosis for the first time in Iraq depend in detected virulence nmuc-1 gene. Phylogenic tree analyses mounted a low genetic variation (0.2) among Iraqi isolate and all other comparison isolates. In conclusion our result indicated that molecular method could diagnosis T. canis larvae infection in any meat or meat products of local or imported from inside or outside Iraq country and used as an accurate microbiological laboratory test used routinely in government
Long-Time Dispersive Estimates for Perturbations of a Kink Solution of One-Dimensional Cubic Wave Equations

A kink is a stationary solution to a cubic one-dimensional wave equation (∂ t 2 − ∂ 2 x )φ = φ − φ 3 that has different lim- its when x goes to −∞ and +∞ , like H(x) = tanh (x/ √ 2 ) ). Asymptotic stability of this solution under small odd perturbation in the energy space has been studied in a recent work of Kowalczyk, Martel, and Muñoz. They have been able to show that the perturbation may be written as the sum a(t)Y(x) + ψ(t,x) , where Y is a function in Schwartz space, a(t) a function of time having some decay properties at infinity, and ψ(t,x) satisfies some local in space dispersive estimate. These results are likely to be optimal when the ini- tial data belong to the energy space. On the other hand, for initial data that are smooth and have some decay at infinity, one may ask if precise dispersive time decay rates for the solution in the whole space-time, and not just for x in a compact set, may be obtained. The goal of this work is to attack these questions.
CURRENCY NOTES AND ASSOCIATED RISK OF NEGLECTED TROPICAL DISEASES: STUDY ON THE NIGERIAN NAIRA

Currency notes could play a role in the transmission of faeco-oral pathogens. This study aimed at identifying the possible role of the Nigerian Naira in the transmission of some neglected tropical diseases (NTDs) and the implication on their intervention and control in Nigeria. Method: 250 samples of all denominations of mint, dirty and mutilated Naira notes were examined for presence of parasites using the rinse method. Result: 58.4% of notes were contaminated with 161 cysts and ova of a protozoan (45.3%) and helminths (54.7%): Entamoeba histolytica cysts (43.7%), Enterobius vermicularis ova (5.4%), Ascaris lumbricoides ova (34.7%) and Hookworm ova (12.6%). Parasite contamination was independent of currency denomination (X2 =45.4; P=0.05). Mutilated notes harboured more parasites (51.5%) than dirty notes (44.9%). Mint notes had zero contamination. This was statistically significant (X2 =5.6; P<0.05). Polymer notes were more contaminated (51.37%) than paper notes. This study has identified a public health risk and the potential role of the Naira notes in the epidemiology of some NTDs in the study area. Public education on the health implications of the abuse of the Naira, beyond reasons of patriotism is required now. The Central Bank should ensure quick withdrawal of mutilated notes from circulation.
The impact of short-term debt on accruals-based earnings management – evidence from Vietnam

Abstract This study seeks to examine the relationship between short-term debt maturity and accruals-based earnings management using a sample of listed firms in Vietnam from 2010–2017. The extant literature remains under-explored on the impact of short-term debt on accruals-based earnings management at low and high levels of short-term debt. We further dissect the impact of the interaction between the growth opportunities and short debt maturity on accruals-based earnings management. Our findings provide evidence suggesting that short-term debt maturity is likely to exert a desirable impact in lowering earnings management at low levels of short-term debt, while at high levels it tends to increase earnings manipulation, demonstrating a U-shaped relationship. Furthermore, we show that growth opportunities moderate the impact of short debt maturity on earnings management. Specifically, the U-shaped pattern between short-term debt and earnings management is pronounced for firms with low growth opportunities, while for high-growth counterparts that pattern weakens.
Rotational Stability of AcrySof Toric Intraocular Lens Over Time: Influence of Capsulorhexis Contraction

To evaluate the rotational stability of AcrySof toric intraocular lenses (IOL) by considering lapse of postoperative time and influence of capsulorhexis contraction. A prospective, masked, single center study was conducted on 19 patients who had undergone microcoaxial cataract surgery and AcrySof toric IOL implantation. Slit-lamp retroillumination photographs of anterior segments were obtained from all patients after 1 week, 1 month and 3 months post-surgery. The degree of alteration of the postoperative IOL axis alignment and the amount of anterior capsular shrinkage were analyzed using Adobe Photoshop software. The mean degree of toric IOL axis misalignment was 2.18 (±20.2) degrees at 3 months follow-up. Quadrant analysis of the capsulorhexis aperture area at 1 week and 1 month post-operative, showed counterclockwise IOL rotation when the capsule contraction was dominant in the haptic part as well as clockwise rotation when dominant in the non-haptic part (p = 0.015). The direction and degree of AcrySof toric IOL rotation differed throughout the follow-up period. Since most misalignments were found on the first post-operative day, physicians should try to minimize peri-operative risk factors that influence IOL rotation. There was also a correlation between the part of anterior capsule contraction and the direction of IOL rotation.
Learning an L2 and L3 at the same time: help or hinder?

ABSTRACT There is quite a bit of evidence showing that the experience of learning an L2 will help in learning an L3, but as far as we know, very little research has investigated the possible impact of L3 learning on the already existing and still developing L2 system within the learner. According to Complex Dynamic Systems Theory (CDST), language development depends on limited resources. In simultaneous L2 and L3 (L2 + L3) learners, these resources have to be used for learning two languages, reducing the resources available for L2 learning. This might lead, firstly, to a slower L2 development in L2 + L3 learners than in L2 only learners, and secondly, to more variability in the L2 during the learning process. In the current study, we traced the L2 English writing proficiency scores (both in terms of gains and variability) of two groups of L1 Chinese learners within one academic year. One group learnt English only (L2) and the other group learnt English and Russian simultaneously. Results show that the L2 + L3 learners did not develop their L2 to a lesser extent than the L2 learners did, but they showed more variability over time in one sub-area (fluency) of L2 writing proficiency. The implications are discussed.
Motivation of University Students Volunteer to Participate in Sportive Activities of Mentally Handicapped Individuals.

The general aim of the study is to determine the motivation of volunteers to participate in the sportive activities of mentally handicapped individuals (Study 1) and to reveal the details that can ensure the continuity of these volunteering activities (Study 2). In Study I, a survey model including the qualitative paradigm was used. Study I was carried out with 138 volunteers who participated in the Special Olympics Turkey event for mentally handicapped individuals in Gazi University. In the study I, an open-ended data collection tool with one question was used to determine the reasons for volunteers to participate in the sportive activities of mentally handicapped individuals. In the study I was used thematic analysis. In study I, It was determined that 121 (Female: 76, Male: 45) volunteers were in the internal motivation sub-dimension, 15 (Female: 4, Male: 11) volunteers were in the external motivation sub-dimension and 2 participants were in the non-motivation sub-dimension. In Study II, it was aimed to examine the expressions of volunteers involved in external motivation and non-motivation dimensions for these dimensions in depth. In Study II, a qualitative research approach was used. Study II was carried out with 17 volunteers involved in the dimensions of External Motivation (n: 15) and Non-motivation among volunteers. In Study II, semi-structured interview form was used as data collection tool. Study II shows the categories and frequencies achieved during interviews with individuals, whose voluntary participation motivations are external motivation and non-motivation. In interviews with volunteers in the external motivation sub-dimension, the following categories were obtained: “Occupational anxiety”, “Increasing the Sincerity with Teachers”, “Gaining Social Status/Becoming Popular” and “Rewarding Voluntary Participation”.
Testing the impact of environmental conditions and matriline on tadpole developmental traits in the European Common Frog, Rana temporaria, in the field

Phenotypic trait variation among populations is frequently studied to explore evolutionary mechanisms of adaptation processes. However, most studies are conducted over large spatial scales making gene flow between organisms unlikely. Here we explored differentiation of developmental traits among individuals within a small spatial area and asked if differences were environmentally induced and / or had a genetic basis. In a common garden approach we compared the development of Rana temporaria tadpoles, developing either in ponds where the clutch had been originally deposited or in alternative ponds. Forest ponds were small to medium sized, geographically close, and all used as breeding sites by the species. Our main findings were: The variation among pond characteristics was sufficient to generate differences in larval developmental traits among ponds. Non-sibling tadpoles developing in a common environment differed in developmental traits. Sibling tadpoles developing under different conditions showed differences in developmental traits. Tadpoles developing in their native environment did not always perform better than ‘foreign’ tadpoles. These results indicate that environmental conditions shape developmental plasticity to some extend (siblings raised under different conditions differed) but that matriline x environment interactions likewise influence the plasticity of developmental traits (non-siblings differed in their reactions within a common environment).
School Staff’s Experiences and Coping Related to the Challenging Behaviour of Children with Smith-Magenis Syndrome in Schools: A Q Methodological Study

ABSTRACT The aim of this study is to use Q methodology to explore how school staff experience the behaviours of children with Smith-Magenis Syndrome (SMS) in school and how they manage working with these children. Q methodology utilises by-person factor analysis to investigate subjectivity. Fourteen school staff of students with SMS in Norway participated and sorted 40 statements according to their own experience working with a student with SMS. Two distinct viewpoints were revealed, namely, 1) Managing challenging aggressive and self-injury behaviours in school where school staff experienced a range of challenging behaviours, especially aggressive behaviours. 2) Struggling with intense non-physical challenging behaviours in school where school staff experienced behaviours such as the students being very intense, craving attention and pushing buttons. In conclusion, there must be a greater emphasis on education and advising and supporting school staff’s work with the non-physical challenging behaviours aspects of teaching children with SMS, as well as a continued focus on challenging aggressive behaviours.
Evaluation of Plaque Removal Efficacy of Dental Floss with/without Chlorhexidine Gel Coating in Patients with Gingivitis - A Clinical and Microbological Study

BACKGROUND: Chlorhexidine has shown anti-plaque and antimicrobial effects when used as a mouthwash and appears to be effective when used as a topical antiseptic agent. AIM: The present study aimed to compare the efficacy of chlorhexidine gel coated dental floss with that of uncoated dental floss. METHODS: This parallel, single-blinded, randomized controlled clinical trial Included 30 patients with moderate to severe gingivitis. The total population was randomly divided into three groups, with ten patients in each group. Group A received dental floss with 1% chlorhexidine gel, and Group B received only dental floss, while in Group C no dental floss was provided. All thirty volunteers were provided with standard toothpaste and toothbrush. Clinical parameters such as gingival index, plaque index, and bleeding index were recorded along with supragingival plaque sample collection for microbiological culture. Subjects were recalled after 15 days and clinical and microbiological analysis was performed. All parameters were re-assessed at the follow up visit after two weeks. RESULTS: All the groups showed a significant reduction in values of plaque index, gingival index, and bleeding index, as well as the microbial counts post-enrollment in the study. A significant reduction in the bleeding indices was noticed in Group A in comparison to C (p < 0.05). CONCLUSIONS: The use of dental floss coated with 1% chlorhexidine gluconate gel was effective as an interproximal aid for patients with moderate to severe gingivitis.

What do I do now? Intolerance of uncertainty is associated with discrete patterns of anticipatory physiological responding to different uncertain contexts

Heightened physiological responses to uncertainty are a common hallmark of anxiety disorders. Many separate studies have examined the relationship between individual differences in intolerance of uncertainty (IU) and physiological responses to uncertainty during different contexts. Despite this, little is known about the extent to which physiological responses during different uncertain contexts covary within individuals based on IU. Anticipatory physiological responses to uncertainty were assessed in three different contexts (associative threat learning, basic threat uncertainty, decision-making) within the same sample (n = 45). During these tasks, behavioural responses (i.e. reaction times, choices), skin conductance and corrugator supercilli activity were recorded. In addition, self-reported IU and trait anxiety were measured. IU made different contributions to the physiological measures during each task. IU was found to modulate both skin conductance and corrugator supercilii activity for the associative threat learning and decision-making contexts. However, trait anxiety was found to modulate corrugator supercilii activity during the basic threat uncertainty context. Ultimately, this research helps us further tease apart the role of IU in different uncertain contexts, which will be relevant for future IU-related models of psychopathology.
Histopathological and immunophenotypical assessment of canine primary splenic lymphoma according to the World Health Organization

ABSTRACT: Although there are several studies addressing multicentric lymphoma in dogs, data regarding splenic lymphoma remains scarce. The diagnosis of splenic lymphoma using the World Health Organization (WHO) classification system can aid prognostic characterization of splenic lymphoma. The aim of this study was to evaluate the most common histological types of splenic lymphoma in dogs from Brazil according to the WHO classification. We assessed 33 cases of splenic lymphoma diagnosed by histopathologic and immunohistochemical (IHC) analysis submitted to VETPAT- Pathology Laboratory, Campinas-SP, Brazil. IHC was performed using antibodies against CD3 for T-cell and CD79α for B-cell identification . Mean age of patients with splenic lymphoma was 9.8 years. The most affected breeds were mixed breed dogs (33%) followed by Pit bulls and Yorkshires (9.0%). The most prevalent histological type was marginal zone B-cell lymphoma (60.7%) followed by diffuse large B-cell lymphoma (12.1%) and lymphoblastic T-cell lymphoma (12.1%). Histological and immunohistochemical characterization of splenic lymphoma is important due to the high prevalence of indolent lymphomas such as marginal zone, which may be less aggressive and thus have different prognostic and distinct forms of treatment when compared to high-grade lymphomas.
Using Artificial Neural Network to Predict Rate of Penetration from Dynamic Elastic Properties in Nasiriya Oil Field

The time spent in drilling ahead is usually a significant portion of total well cost. Drilling is an expensive operation including the cost of equipment and material used during the penetration of rock plus crew efforts in order to finish the well without serious problems. Knowing the rate of penetration should help in speculation of the cost and lead to optimize drilling outgoings. Ten wells in the Nasiriya oil field have been selected based on the availability of the data. Dynamic elastic properties of Mishrif formation in the selected wells were determined by using Interactive Petrophysics (IP V3.5) software based on the las files and log record provided. The average rate of penetration and average dynamic elastic properties for the studied wells was determined and listed with depth. Laboratory measurements were conducted on core samples selected from two wells from the studied wells. Ultrasonic device was used to measure the transit time of compressional and shear waves and to compare these results with log records. The reason behind that is to check the accuracy of the Greenberg-Castagna equation that was used to estimate the shear wave in order to calculate dynamic elastic properties. The model was built using Artificial Neural Network (ANN) to predict the rate of penetration in Mishrif formation in the Nasiriya oil field for the selected wells. The results obtained from the model were compared with the provided rate of penetration from the field and the Mean Square Error (MSE) of the model was 3.58 *10-5.
