MEDIA E CONTESTO DELL’EDUCAZIONE SCIENTIFICA IN TPACK: UNA REVISIONE SISTEMATICA Abstract The development of media and context within the framework of Technological Pedagogical and Content Knowledge (TPACK) is important in science education. The purpose of the systematic review is to find out the media and context used in the TPACK framework for the development of science learning. Media is related to learning technology such as technology in communication, collaboration, assessment, visualization, and online learning. The use of science learning media in developing TPACK consists of two types, the first using a single type of media and the second using multiple types of learning technology media. The learning context includes micro in the form of classes, meso in the form of schools, and macro in the form of the wider community, as well as the context of teachers and pre-service teachers. The context of science education in TPACK relates to the type of research such as micro-level using mixed research methods, experimental, qualitative, research and development, and macro level usually using survey research. The TPACK framework is an approach to explaining effectiveness, evaluation, and reflection in the use of learning technology.

SUPPORT TEACHERS AND INCLUSIVE EDUCATION: A STUDY ON ATTITUDES, SELF-EFFICACY, SELF-ASSESSMENT OF KNOWLEDGE AND SKILLS, AND BEHAVIORS IN THE CLASSROOM Abstract This exploratory study analyzes attitudes toward inclusion, self-efficacy in implementing inclusive education, knowledge, and skills for managing pupils with special needs, and behaviors implemented for school inclusion in a sample of 391 support teachers without specialization. The results highlight favorable attitudes towards inclusion but reveal the persistence of beliefs that justify the separation of students with special needs. Teachers report a good level of self-efficacy in inclusion but perceive themselves to be less competent in managing classroom dynamics. Many teachers, while perceiving themselves as skilled in managing relationships with colleagues and planning, perceive gaps in the knowledge and skills needed to implement effective inclusive education. Especially self-efficacy in implementing inclusive education appears to be related to knowledge, skills, and inclusive behaviors. This research suggests the need to strengthen the training of support teachers and promote inclusive behaviors to ensure effective inclusion.

Published: July 2024

Recykling materiałów w budownictwie drogowym jest ważnym zagadnieniem w aspekcie ochrony środowiska oraz optymalizacji kosztów przedsięwzięć drogowych. W celu poprawienia właściwości lepiszczy asfaltowych coraz częściej stosuje się modyfikację dodatkami rozdrobnionej gumy ze zużytych opon samochodowych. Uzyskane w wyniku tej modyfikacji lepiszcza gumowo-asfaltowe charakteryzują się, podobnie jak polimeroasfalty, polepszonymi właściwościami lepkosprężystymi. Wykazują one jednak wyższą niż polimeroasfalty odporność na działanie niskiej temperatury. Wykorzystanie rozdrobnionej gumy z recyklingu opon samochodowych jest uzasadnione również ze względów ekologicznych i stanowi najlepszy sposób zagospodarowania odpadów gumowych. W artykule przedstawiona została analiza porównawcza właściwości lepkosprężystych lepiszczy gumowo-asfaltowych, która obejmowała ocenę właściwości w zakresie niskich, średnich i wysokich temperatur. Lepiszcza poddano badaniom w zakresie podstawowych wymagań przewidzianych dla asfaltów modyfikowanych, badaniom konsystencji w zakresie temperatur technologicznych oraz zaawansowanym badaniom reologicznym w reometrze dynamicznego ścinania oraz reometrze zginanej belki. Przedstawione zostały przykłady zastosowania lepiszczy gumowo-asfaltowych w realizacjach odcinków drogowych w Polsce. W podsumowaniu sformułowane zostały wnioski dotyczące możliwości modyfikacji, właściwości oraz zastosowania lepiszczy asfaltowych modyfikowanych dodatkiem miału gumowego ze zużytych opon samochodowych.

Published: June 2013

BackgroundThis paper synthesizes research on the contribution of workplace injustices to occupational health disparities.MethodsWe conducted a broad review of research and other reports on the impact of workplace discrimination, harassment, and bullying on workers' health and on family and job outcomes.ResultsMembers of demographic minority groups are more likely to be victims of workplace injustice and suffer more adverse outcomes when exposed to workplace injustice compared to demographic majority groups. A growing body of research links workplace injustice to poor psychological and physical health, and a smaller body of evidence links workplace injustice to unhealthy behaviors. Although not as well studied, studies show that workplace injustice can influence workers' health through effects on workers' family life and job‐related outcomes.ConclusionInjustice is a key contributor to occupational health injustice and prospective studies with oversample of disadvantaged workers and refinement of methods for characterizing workplace injustices are needed.

The changing face of thyroid cancer in a population‐based cohort
Authors: Alok Pathak K. , Leslie William D. , Klonisch Thomas C. , Nason Richard W. 
Published: June 2013

AbstractIn North America, the incidence of thyroid cancer is increasing by over 6% per year. We studied the trends and factors influencing thyroid cancer incidence, its clinical presentation, and treatment outcome during 1970–2010 in a population‐based cohort of 2306 consecutive thyroid cancers in Canada, that was followed up for a median period of 10.5 years. Disease‐specific survival (DSS) and disease‐free survival were estimated by the Kaplan–Meier method and the independent influence of various prognostic factors was evaluated by Cox proportional hazard models. Cumulative incidence of deaths resulting from thyroid cancer was calculated by competing risk analysis. A P‐value <0.05 was considered to indicate statistical significance. The age standardized incidence of thyroid cancer by direct method increased from 2.52/100,000 (1970) to 9.37/100,000 (2010). Age at diagnosis, gender distribution, tumor size, and initial tumor stage did not change significantly during this period. The proportion of papillary thyroid cancers increased significantly (P < 0.001) from 58% (1970–1980) to 85.9% (2000–2010) while that of anaplastic cancer fell from 5.7% to 2.1% (P < 0.001). Ten‐year DSS improved from 85.4% to 95.6%, and was adversely influenced by anaplastic histology (hazard ratio [HR] = 8.7; P < 0.001), male gender (HR = 1.8; P = 0.001), TNM stage IV (HR = 8.4; P = 0.001), incomplete surgical resection (HR = 2.4; P = 0.002), and age at diagnosis (HR = 1.05 per year; P < 0.001). There was a 373% increase in the incidence of thyroid cancer in Manitoba with a marked improvement in the thyroid cancer‐specific survival that was independent of changes in patient demographics, tumor stage, or treatment practices, and is largely attributed to the declining proportion of anaplastic thyroid cancers.

ObjectivesThe objective of this study was to describe our single‐institution experience with prenatal atrial septal stent placement for fetuses with hypoplastic left heart syndrome and an intact atrial septum (HLHS/IAS).BackgroundInfants born with HLHS/IAS are at high risk for neonatal death, despite maximal postnatal therapy. Prenatal atrial septoplasty by static balloon dilation has been effective in decompressing the left atrium (LA) in utero, but several factors have limited the size of septal defects. We attempted to overcome the limitations of balloon septoplasty using transcatheter atrial septal stents.MethodsAll records from our institution of fetuses with HLHS/IAS that underwent prenatal atrial septal stent placement were reviewed, including operative notes and echocardiograms.ResultsNine fetuses between 24 and 31 weeks gestation with HLHS/IAS underwent attempted fetal atrial septal stent placement. A stent was deployed across the atrial septum in five fetuses, with four fetuses demonstrating flow across the stent at the time of intervention. In four cases, stent placement failed due to malposition or embolization, but in three of the four cases, atrial balloon septoplasty at the same in‐utero procedure successfully and acutely decompressed the LA. There were no maternal complications. There was one fetal demise. The remaining eight fetuses survived to delivery, but four died in the neonatal period (two of which had been stented).ConclusionsUltrasound‐guided atrial septal stent placement is feasible in some fetuses with HLHS/IAS. Visualization of the septum and catheter tip is critical to technical success. Additional experience is necessary to determine the clinical impact of this intervention. © 2013 Wiley Periodicals, Inc.

AbstractCytochrome B sequences and allozymes reveal complex patterns of molecular variation in dusky salamander (Desmognathus) populations in eastern Tennessee. One group of allozymically distinctive populations, which we refer to as the Sinking Creek form (SCF), combines morphological attributes of Desmognathus fuscus with cytB sequences characteristic of Desmognathus carolinensis. This form is abruptly replaced by D. fuscus just north of Johnson City, TN with no evidence of either sympatry or gene exchange. To the south, allozymic markers indicate a broad zone of admixture with populations characterized by distinct cytB sequences and that may or may not be ultimately referable to Desmognathus conanti. A third distinctive group of populations, which we refer to as the Lemon Gap form (LGF), occurs in the foothills of the Great Smoky and southern Bald Mountains and exchanges genes with Desmognathus santeetlah along the escarpment of the Great Smokies, D. carolinensis in the southern Bald Mountains, and populations of a different haplotype clade in the Ridge and Valley. We treat all these as innominate forms that may represent “failed species,” recognizing that it may never be possible to reconcile species limits with patterns of phylogeny, morphology, and gene exchange in these salamanders.
THE DYNAMICS OF REAL EXCHANGE RATES: A RECONSIDERATION
Authors: Kaufmann Hendrik , Heinen Florian , Sibbertsen Philipp 
Published: June 2013

SUMMARYIn this paper we offer a bootstrap‐based version of the Cox specification test for non‐nested hypothesis to discriminate between ESTAR and MSAR models. Both models are commonly used for modeling real exchange rates dynamics. We show that the test has good size and power properties in finite samples. In an application, we analyze several major real exchange rates to shed light on the question of which model describes these processes best. This allows us to draw conclusions about the driving forces of real exchange rates. Copyright © 2013 John Wiley & Sons, Ltd.
Transglutaminase‐2 mediates calcium‐regulated crosslinking of the Y‐Box 1 (YB‐1) translation‐regulatory protein in TGFβ1‐activated myofibroblasts
Authors: Willis William L. , Hariharan Seethalakshmi , David Jason J. , Strauch Arthur Roger 
Published: June 2013

ABSTRACTMyofibroblast differentiation is required for wound healing and accompanied by activation of smooth muscle α‐actin (SMαA) gene expression. The stress‐response protein, Y‐box binding protein‐1 (YB‐1) binds SMαA mRNA and regulates its translational activity. Activation of SMαA gene expression in human pulmonary myofibroblasts by TGFβ1 was associated with formation of denaturation‐resistant YB‐1 oligomers with selective affinity for a known translation‐silencer sequence in SMαA mRNA. We have determined that YB‐1 is a substrate for the protein‐crosslinking enzyme transglutaminase 2 (TG2) that catalyzes calcium‐dependent formation of covalent γ‐glutamyl‐isopeptide linkages in response to reactive oxygen signaling. TG2 transamidation reactions using intact cells, cell lysates, and recombinant YB‐1 revealed covalent crosslinking of the 50 kDa YB‐1 polypeptide into protein oligomers that were distributed during SDS–PAGE over a 75–250 kDa size range. In vitro YB‐1 transamidation required nanomolar levels of calcium and was enhanced by the presence of SMαA mRNA. In human pulmonary fibroblasts, YB‐1 crosslinking was inhibited by (a) anti‐oxidant cystamine, (b) the reactive‐oxygen antagonist, diphenyleneiodonium, (c) competitive inhibition of TG2 transamidation using the aminyl‐surrogate substrate, monodansylcadaverine, and (d) transfection with small‐interfering RNA specific for human TG2 mRNA. YB‐1 crosslinking was partially reversible as a function of oligomer‐substrate availability and TG2 enzyme concentration. Intracellular calcium accumulation and peroxidative stress in injury‐activated myofibroblasts may govern SMαA mRNA translational activity during wound healing via TG2‐mediated crosslinking of the YB‐1 mRNA‐binding protein.

Published: June 2013

AbstractBACKGROUNDBiofiltration of methane is of particular interest to contribute to limiting the greenhouse gas effect of biogas emissions from landfills. The complexity of the biogas mixture from landfills has underlined the importance of the presence of non‐methane organic compounds. The aim of this study was to determine the effect of toluene on the microkinetic and macrokinetic parameters of methane biodegradation using an inorganic filter bed.RESULTSTwo concentrations of toluene were tested, 0.7 and 3.4 gC m−3, and compared with the case of methane biofiltration alone. The specific growth rates of methane decreased from 0.793 to 0.574 to 0.278 d−1 when the toluene concentration was increased from 0 to 0.7 to 3.4 gC m−3, respectively. The maximum elimination capacity of methane decreased from 39.4 to 5.6 gC m−3 h−1 when toluene concentration was increased from 0 to 3.4 gC m−3. The half‐saturation constants decreased from 4.6 to 1.6 gC m−3 and from 4.6 to 0.7 gC m−3, respectively.CONCLUSIONSResults show that an inhibition occurred on methane biodegradation when toluene was introduced into the biofilter. © 2013 Society of Chemical Industry

AbstractBackgroundThe precise role of microRNAs in inflammatory disease is not clear. The present study investigated the effect of microRNA (miR‐146b) with respect to improving intestinal inflammation.MethodsThe microRNA profile in interleukin‐10 deficient mice was examined using microRNA arrays and miR‐146b was selected for the subsequent experiments. The expression vectors containing either the whole sequence of miR‐146b or small interfering RNA for miR‐146b were intraperitoneally administered to the dextran sodium sulfate (DSS)‐induced colitis mouse. The expression levels of inflammation‐related mediators were examined by the reverse transcriptase‐polymerase chain reaction and western blotting analysis. Intestinal barrier function was evaluated by an ex vivo mannitol flux study.ResultsThe overexpression of miR‐146b activated the NF‐κB pathway, improved epithelial barrier function, relieved intestinal inflammation in the DSS‐induced colitis mice, and improved the survival rate of mice with lethal colitis. Furthermore, this amelioration of intestinal inflammation by miR‐146b was negated by the inhibitor for the NF‐κB pathway. The overexpression of miR‐146b decreased the expression of siah2, which has a target sequence for miR‐146b, and promoted the ubiquitination of TRAF proteins. This suggests that the up‐regulation of NF‐κB by miR‐146b was mediated by inhibition of the ubiquitination of TRAF proteins upstream of NF‐κB.ConclusionsmiR‐146b improves intestinal inflammation by up‐regulating NF‐κB as a result of the decreased expression of siah2, which ubiquitinates TRAF proteins. Modulation of the miR‐146b expression is a potentially useful therapy for the treatment of intestinal inflammation via activation of the NF‐κB pathway. Copyright © 2013 John Wiley & Sons, Ltd.
Moist dynamics of active/break cycle of Indian summer monsoon rainfall from NCEPR2 and MERRA reanalysis
Authors: Pillai Prasanth A. , Sahai A. K. 
Published: June 2013

ABSTRACTThe vertically integrated moisture and moist static energy (MSE) budgets during the active and break phases of Indian summer monsoon are studied using National Centers for Environmental Prediction Reanalysis2 (NCEPR2) and Modern Era Retrospective Analysis for Research and Applications (MERRA) data. The different parameterization procedures adopted by the reanalysis models will impose inevitable differences between the reanalysis products, which will make an impact on their intraseasonal oscillation (ISO) also. At the same time, the agreement of the moisture budget terms of the reanalysis products has enabled us to come up with a common moisture mechanism responsible for the ISO. Estimates of the moisture budget indicates that the rainfall anomalies over the Indian monsoon region in both active and break phases are mainly (70–80%) balanced by local moisture divergence. The remaining 20–25% is accounted by the horizontal moisture advection. The moisture advection is found to lead the rainfall by 8–9 d, while there is no lead‐lag relationship is observed between the moisture divergence and rainfall. The anomalous moisture advection from the northwest pacific initiates the active phase of Indian monsoon and the dry air advection from the northwest of India after the onset of active convection sets off the break conditions. MSE budget over India is balanced by MSE divergence and moisture advection, indicating that the variation in MSE is mainly governed by moisture in the intraseasonal timescales. A positive covariance between radiative and surface fluxes and precipitation anomalies indicates that these flux terms slowdown the variation of MSE during active/break phase and may help to extend the ISO. The anomalous moisture advection has a major role in northward propagation of ISO also. A large residual of MSE budget during onset of ISO is the main caveat of the reanalysis products and it is the major constrain in the present analysis also.

Published: June 2013

ABSTRACTWe investigated whether the implantation of juvenile allograft and minced meniscal fragments could improve the healing of avascular meniscal injuries, which cannot heal spontaneously. Concentric cylindrical explants were excised from the inner two‐thirds of swine medial menisci. The inner cylinder consisted of a “sandwich” structure, with minced juvenile meniscal fragments, juvenile meniscal columns, minced mature meniscal fragments, or mature meniscal columns implanted in the middle. The explants were cultured in vitro for 2, 4, or 6 weeks. Interfacial meniscal repair was assessed by histology, immunohistochemistry, biomechanical testing, and confocal laser scanning microscopy. Histology and confocal microscopy results revealed that tissue repair and cell accumulation at the interface were best at all time points in the juvenile meniscal fragments group, followed by the juvenile columns, minced mature fragments, and mature columns groups, respectively. At 6 weeks, the implantation of juvenile allograft and minced meniscal fragments increased the shear strength, peak force, and energy to failure in the peripheral interface. Picosirius red/polarized light microscopy and immunohistochemistry results showed concurrent expression of type I and II collagen in the interfacial repair tissue. In conclusion, implantation of juvenile allograft and minced meniscal fragments could increase the healing of avascular meniscal injury in vitro. © 2013 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Published: June 2013

ABSTRACTObjectiveTo find reasons for the births of severe β‐thalassemia at a tertiary obstetric hospital in mainland China.MethodsAll cases with confirmed diagnosis of β‐thalassemia major were included from 1 January 2007 to 31 December 2011. The main clinical characteristics of the affected pregnancies were reviewed, including maternal reproductive history, prenatal care in the current pregnancy, the gestation of pregnancy at the time of booking, and availability of husbands for a screen test.ResultsA total of nine cases of β‐thalassemia major were identified at birth during the study period. The reasons for no prenatal diagnosis included unavailability of the father for a test in four cases, unacceptability of the invasive procedure in two cases, absence of prenatal care in two cases, and nonpaternity in one case.ConclusionThe effectiveness in control of the disease is not only associated with the model itself but also the factors playing against the model. The identification of the main reasons for the birth of severe thalassemia might help to find room for improvement in clinical practice. © 2013 John Wiley & Sons, Ltd.
