Unveiling Sociocultural Dynamics & Vygotskian Insights on EFL Learners' Anxiety in Turkey
Authors: Hosseini Taner 
Published: March 2024

In this study, foreign language anxiety (FLA) has been considered as an effect caused by sociocultural factors, which EFL students experience in a Turkish setting. As Horwitz holds, FLA is a distinct complex construct of self-perception and beliefs arising from the uniqueness of the language learning process. Likewise, as stated by Spielberger (1983) anxiety is nothing but the subjective feeling of tension, apprehension …associated with the arousal of the autonomic nervous system, whereas Scovel (1978) states anxiety is an ambiguous affective variable to be made clear by distinguishing between debilitative and facilitative anxiety.
This research approaches FLA as a variable derived from the sociocultural theory (SCT) of Vygotsky (1978). Based on SCTof Vygotsky, this study aspires to find out whether or not the sociocultural factors (SCFs) such as attitudes and beliefs (self-regulation, scaffolding, peer interaction, feedback, and private speech) inflict anxiety on EFL learners in a Turkish setting. To investigate how those factors interplay with students’ anxiety and achievement, a questionnaire of anxiety called FLCAS by Horwitz et al. (1986) was administered to EFL students at three different universities in Istanbul, Turkey. The FLCAS was first given to 370 students from three different universities to fill it out on a psychometric Likert Scale, but only 273 of the population were picked out for the thesis aim since the downsized population had fully completed the questionnaire with the information needed.
In order to ascertain and validate if the pertinent factors of SCFs could be defined to function as potential anxiety-provoking factors in the FLCAS, factor analysis (FA) was employed using SPSS version 25.0. What’s more, extracting the reliable factor loadings of the SCFs on FLCAS proved that the SCFs could be designated as a new dimension for the questionnaire.
The findings were reported to indicate that there exists a confluently significant relationship between SCFs and language anxiety in a Turkish environment.
The SCFs and students’ achievement, as well as TA caused by the SCFs, are negatively correlated holding negative statistics with an exception for the peer interaction (PI) not holding a significant p-value. Furthermore, it became evident that students’ belittling attitude of their foreign language competence would make them experience English language learning deficiency due to being exposed to the vortex of potential xenoglossophobia.
The negative or downhill correlation is indicative of the fact that once one of the SCFs escalates both TA and EFL learners’ achievement would nosedive.

Distribution pattern of weed seedbank in strip and bed planted sandy clay loam soil after five years of cropping in Bangladesh
Authors: Hossain Mobarak , Begum M , Rahman M M 
Published: March 2024

Tillage practices can alter the distribution of weed seedbank and might be a useful tool for integrated weed management. The objective of this shade house experiment was to study the effects of strip planting (SP) and bed planting (BP) relative to conventional tillage (CT) with increased residue mulching (20 vs. 50%) of previous crops on the floristic composition of weeds in the field. A five-years longer conservation agriculture experiment was sampled from the Rajshahi district of Bangladesh. The weed seedbank in 0-15 cm soil was quantified by assessing weeds emergence during January-December 2016. The year-round count of emerged weeds revealed the fewest number of weed species (especially broadleaf weeds) and lowest weed density in SP, followed by CT and BP with 50% mulches. The SP and BP produced a higher number of perennials weeds than annual weeds, which was the opposite of CT. Therefore, it could be concluded that continuous practice of SP and increased crop residue retention for five years decreased the weed seedbank size. Still, they increased the relative proliferation of perennial weeds compared to CT. Weed seedbank size in SP was even smaller than BP.

Published: March 2024

OBJECTIVE: To evaluate the costs and benefits associated with the use of biologics and Janus kinase inhibitors (JAKi) for the treatment of bio-experienced patients suffering from ulcerative colitis in Italy.METHODS: This pharmacoeconomic analysis compared JAKi (filgotinib, tofacitinib and upadacitinib) and biologics (vedolizumab and ustekinumab). A decision tree model with a 1-year time horizon was built in MS Excel in order to estimate treatment cost and clinical efficacy expressed in terms of clinical response (CR), clinical remission (CRe) and mucosal healing (MH). Efficacy of each treatment was estimated using relative risks elaborated from a recent network meta-analysis of 17 RCTs. The investigated population concerned patients previously treated with biologic drugs (bio-experienced). Both induction and maintenance phases were considered and dose escalation (when allowed) was planned for patients not reaching an appropriate response after induction. Outcomes included total treatment cost (acquisition and administration), overall response rate, and cost per responder at one year.RESULTS: According to the model results, the treatment associated with the best clinical response at 1 year was vedolizumab (69.6%) followed by filgotinib (60.9%) and upadacitinib (60.1%). Despite differences in efficacy, filgotinib resulted in the lowest cost per responder, in every outcome, compared with all the other alternatives. The same trend applies when observing results at the end of the induction phase only. Results were robust to probabilistic sensitivity analyses, filgotinib has a posterior probability to be better than the other alternatives higher than 96% according to all the three response definitions (CR, CRe, and MH).CONCLUSIONS: Generally, JAKis and vedolizumab were associated with higher treatment response. Among the alternatives included in the analysis, filgotinib has the lowest cost per responder for all the outcomes included. These findings could help deliver more effective and efficient healthcare in the NHS.

Published: March 2024

Objective: It was aimed to explore the correlation between demographic characteristics and the presence of comorbidity in the antibody response after the second dose of vaccination in healthcare workers in this study. In addition, the third and fourth dose approaches of the participants and the protection of the antibody levels formed by the two doses of vaccine against COVID-19 were examined observationally.
Materials and Methods: Health workers, whose NCP and S protein antibody levels were detected on the 30th day after the second dose of the CoronaVac vaccine, were followed up in terms of being vaccinated for the third and fourth doses and having COVID-19.
Results: Higher levels of S antibodies were detected in women after two doses of vaccination (p=0.001). It was pointed out that smoking has a negative effect on the antibody response after vaccination (p=0.008). People who had pre-vaccine COVID-19 had higher NCP antibody levels after two doses of vaccination (p=0.013). Of the participants, 152 (97.4%) were vaccinated with the third dose and 110 (70.5%) with the fourth dose.
Conclusion: The antibody response after two doses of inactivated CoronaVac® vaccination probe is significantly higher in women, younger people, non-smokers, and people who have not been previously infected with the SARS-CoV-2.
Enzyme‐responsive PARACEST MRI contrast agents: a new biomedical imaging approach for studies of the proteasome
Authors: Yoo Byunghee , Raam Manu S. , Rosenblum Rachel M. , Pagel Mark D. 
Published: August 2007

AbstractProteases are important biomarkers for many biological processes and are popular targets for therapeutics investigations. A protease can be detected by monitoring changes in the paramagnetic chemical exchange saturation transfer (PARACEST) effect of a MRI contrast agent that serves as a substrate for the protease. To translate this type of responsive PARACEST MRI contrast agent to in vivo applications, the sensitivity, timing, specificity and validation of the response of the agent must be evaluated. This report demonstrates that PARACEST MRI contrast agents can be used to detect nanomolar concentrations of proteases, can be designed to preferentially detect the protease caspase‐3 relative to caspase‐8, and can be detected within the 15 min time frame of typical MRI studies. The response can be validated using an unresponsive PARACEST MRI contrast agent as a control. A survey of the MEROPS database shows that this approach may also be applied to detect other proteases, and therefore may represent a new platform technology for studies of the proteasome.

Dynamic stability of the three‐dimensional axisymmetric Navier‐Stokes equations with swirl
Authors: Hou Thomas Y. , Li Congming 
Published: August 2007

AbstractIn this paper, we study the dynamic stability of the three‐dimensional axisymmetric Navier‐Stokes Equations with swirl. To this purpose, we propose a new one‐dimensional model that approximates the Navier‐Stokes equations along the symmetry axis. An important property of this one‐dimensional model is that one can construct from its solutions a family of exact solutions of the three‐dimensionaFinal Navier‐Stokes equations. The nonlinear structure of the one‐dimensional model has some very interesting properties. On one hand, it can lead to tremendous dynamic growth of the solution within a short time. On the other hand, it has a surprising dynamic depletion mechanism that prevents the solution from blowing up in finite time. By exploiting this special nonlinear structure, we prove the global regularity of the three‐dimensional Navier‐Stokes equations for a family of initial data, whose solutions can lead to large dynamic growth, but yet have global smooth solutions. © 2007 Wiley Periodicals, Inc.
The role of FoxC1 in early Xenopus development
Authors: Cha J.Y. , Birsoy B. , Kofron M. , Mahoney E. , Lang S. , Wylie C. , Heasman J. 
Published: August 2007

AbstractFoxC1 is an important transcription factor in vertebrate development since its mutation in humans results in Axenfeld‐Rieger syndrome. In the mouse, disturbance of its function causes congenital hydrocephalus and abnormalities in the development of various mesodermal derivatives. In this report, we provide one mechanistic basis for the requirement for FoxC1 in vertebrate development. We find that, in Xenopus laevis embryos, FoxC1 expression is regulated by the maternal T‐box transcription factor VegT, via the nodal sub‐family of TGFβ signaling transducers. We show that at the late neurula to early tailbud stage, FoxC1 depletion causes the down‐regulation of adhesion molecules, EP and E cadherin, as well as members of the Ephrin/EphR signaling families in the mesoderm germ layer resulting in the loss of adhesion and apoptosis of mesodermal cells.

Regulation of adult intestinal epithelial stem cell development by thyroid hormone during Xenopus laevis metamorphosis
Authors: Ishizuya‐Oka Atsuko , Shi Yun‐Bo 
Published: August 2007

AbstractDuring amphibian metamorphosis, most or all of the larval intestinal epithelial cells undergo apoptosis. In contrast, stem cells of yet‐unknown origin actively proliferate and, under the influence of the connective tissue, differentiate into the adult epithelium analogous to the mammalian counterpart. Thus, amphibian intestinal remodeling is useful for studying the stem cell niche, the clarification of which is urgently needed for regenerative therapies. This review highlights the molecular aspects of the niche using the Xenopus laevis intestine as a model. Because amphibian metamorphosis is completely controlled by thyroid hormone (TH), the analysis of TH response genes serves as a powerful means for clarifying its molecular mechanisms. Although functional analysis of the genes is still on the way, recent progresses in organ culture and transgenic studies have gradually uncovered important roles of cell–cell and cell–extracellular matrix interactions through stromelysin‐3 and sonic hedgehog/bone morphogenetic protein‐4 signaling pathway in the epithelial stem cell development.

Influence of Environmental Variables on Stream Caddis Larvae in Three Slovenian Ecoregions: Alps, Dinaric Western Balkans and Pannonian Lowland
Authors: Urbanič Gorazd , Toman Mihael J. 
Published: August 2007

AbstractIdentification of the environmental variables that influence caddis larvae was performed on 504 samples collected at 94 sites within the three ecoregions of Slovenia; the Alps, the Dinaric western Balkans and the Pannonian lowland. Canonical Correspondence Analysis (CCA) was performed to find sig‐nificantly influential variables and compare their absolute and relative importance in structuring caddisfly assemblages in the different ecoregions. Altogether, 234 variables were considered. According to their type of influence on organisms, variables were classified as indirectly influential variables (e.g., altitude), and directly influential variables or ecological factors (e.g., temperature). Caddis larvae responses were characterized as log abundances of 132 taxa, of which 126 were identified at the species level. The absolute and relative influences of the same environmental variable were found to be different in the selected ecoregions. Of the ecological factors, temperature (maximum and range) was found to be the most important in both mountainous ecoregions (Alps and Dinaric western Balkans). In the Pannonian lowland ecoregion, periodicity was the most influential factor. Of the indirectly influential variables, those that were good predictors of caddis larvae assemblages in the mountainous ecoregions were relatively unimportant in the Pannonian lowland ecoregion. Differences among ecoregions were also found in the cumulative explained variation in the caddisfly distribution, which was the highest in the Alps and the lowest in the Pannonian lowland.

Food Habits of Four Bottom‐Dwelling Gobiid Species at the Confluence of the Danube and Hron Rivers (South Slovakia)
Authors: Adámek Zdeněk , Andreji Jaroslav , Gallardo José Martín 
Published: August 2007

AbstractSince 1997, three newNeogobiusspecies (Neogobius kessleri,N. fluviatilisandN. melanostomus) have been regularly recorded in the Slovak part of the Danube River, formerly inhabited only by one native gobiid species (Proterorhinus marmoratus). The study of their food habits proved that the amphipodCorophium curvispinum,chironomid larvae and pupae, caddis fly larvae (Hydropsychesp.) and mayfly nymphs (Ephoron virgo,Potamanthus luteus) were the most important food items contributing to the similarity of the diets of the gobiid species. Fish (0+Zingel zingelandSander lucioperca) appeared in the diet ofN. kesslerionly. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The Energy Basis of the Consumer Community in Streams Yesterday, Today and Tomorrow …
Authors: Leichtfried Maria 
Published: August 2007

AbstractOrganic matter is the basic source of energy for consumers in ecosystems. In lotic ecosystems, most of the organic matter is allochthonous, imported as bank runoff or as aerial drift. Bank runoff is already processed soil material, particulate or dissolved. Unprocessed plant litter represents the aerial drift. The energy content of unprocessed organic matter is not readily available to consumers; it has to be processed by the microbial community. Microorganisms are most active in biofilms, comprised of fungi, bacteria, protozoa etc., and their organic excretions attached to surfaces. The colonizable surface area in sediments is negatively correlated with the grain size. Therefore, the largest amounts of organic matter are likely to occur in small grain size classes, which shows that biofilms are an important component of the organic matter pool. Most of the meiobenthic species, which play also a very important role in these processes, are closely connected to biofilms. These and their associated communities are doubtless an important food source for benthic consumers. The main energy pathway passes from organic matter (either particulate or dissolved) to the microbial community in biofilms, which transforms the organic matter and makes it available and palatable to benthic consumers. Wherever the benthic community is living, either in bed sediments or on macrophytic surfaces, the energy stored in biofilms or their associated communities is mostly used.
