The Influence of Educational Programme on Teachers' Error Correction Preferences in the Speaking Skill: Insights from English as a Foreign Language Context.

In the area of language teaching, corrective feedback is one of the popular and hotly debated topics that have been widely explored to date. A considerable number of studies on students’ preferences of error correction and the effects of error correction approaches on student achievement do exist. Moreover, much on teachers’ preferences of error correction approaches has also been explored. However, less seems to be done with regard to teachers’ practices of error correction approaches, especially in the area of English as a Foreign Language (EFL). The present study explored EFL teacher’s preferences of error correction approaches in the speaking skill, and further focused on whether the teachers were able to employ the approaches they preferred in their classrooms. Data were collected from a group of 17 EFL teachers, through semi-structured interviews and classroom observations. The findings revealed that although the teachers had clear preferences for error correction approaches, they could not employ them in their classrooms owing to the educational programme constraints. Furthermore, it was observed that they often had to adopt approaches that they were not actually in favour of. Implications for programme and curriculum designers are further discussed.
An extensive photometric study of the Blazhko RR Lyrae star MW Lyr – II. Changes in the physical parameters★

The analysis of the multicolour photometric observations of MW Lyr, a large modulation amplitude Blazhko variable, shows for the first time how the mean global physical parameters vary during the Blazhko cycle. About 1-2 per cent changes in the mean radius, luminosity and surface effective temperature are detected. The mean radius and temperature changes are in good accordance with pulsation model results, which show that these parameters do indeed vary within this order of magnitude if the amplitude of the pulsation changes significantly. We interpret the phase modulation of the pulsation to be a consequence of period changes. Its magnitude corresponds exactly what one expects from the detected changes of the mean radius assuming that the pulsation constant remains the same during the modulation. Our results indicate that during the modulation the pulsation remains purely radial, and the underlying mechanism is most probably a periodic perturbation of the stellar luminosity with the modulation period.
Media Credibility Perception Among Millennials in Slovakia

Motivation is an important tool which can have a signifi cant impact to improve the performance of employees in any organization and in the current competitive world, employees’ commitment is crucial in achieving the organizational goals. The current research is aimed at examining the role played by motivation in sustaining the commitment of sales professionals. Primary data has been collected among 100 sales professionals using the close-ended questionnaire. For the analysis purpose both descriptive and inferential analysis has been conducted. The fi ndings from the analysis show that most factors included in the model to measure the motivation show a signifi cant and positive impact. Similarly the coeffi cient for organizational support, psychological support and fi nancial support shows a positive and signifi cant impact. In examining the impact of increased motivation on employees’ commitment, the results were also statistically signifi cant and positive. On the basis of the fi ndings it can be concluded that the motivation has a signifi cant and positive impact on employees’ commitment so organizations should focus on motivating their employees; however, the method used for motivation can differ from one organization to another.
Situational Position and Student Choice Criteria

The student in choosing a particular university to attend does so within a particular university-student situational context. This paper demonstrates that the situational context significantly influences the evaluative criteria used by students in deciding which university to attend. Using a Canadian university as a case study, the authors develop an analytical framework for understanding the relationship between the particular university-student situational context and the student choice of university decision criteria.
Immobility and insecure labour markets: An active response to precarious employment

This article explores how people experience and respond to a post-industrial labour market context through residential (im)mobility. Focusing on places that are represented through a range of official measures as ‘declining’, the research explains why people may remain in weaker labour market areas, rather than moving to places that could offer greater employment opportunities. The case study approach focused on two urban neighbourhoods in England, Nearthorpe (Sheffield) and Eastland (Grimsby). The article draws on repeated, in-depth, biographical interviews with 25 individuals across 18 households. The research shows that stability of residence was a necessary counterbalance to a low-paid and insecure work context. Immobility facilitated access to a range of informal support networks. However, immobility was not simply a by-product of lack of mobility or a passive state. This research conceptualises immobility as an active process in which participants engaged in different forms of adaptation and resistance in the face of changing labour market conditions.
Does examinee motivation moderate the relationship between test consequences and test performance

There is substantial evidence that the disposition of test takers is central to performance. This research extends previous work by replicating the experimental design of L. Wolf and J. Smith (1995) and conducting a secondary analysis of their data to attempt to demonstrate differential effect sizes for examinees reporting varying motivation levels in consequences versus no-consequences situations. The second phase of the study investigated the hypothesis that examinee motivation and item type moderate the relationship between test consequences and test performance by expanding the Wolf and Smith design to include multiple-choice and essay test items. Ninety undergraduate psychology majors participated in the study. The study supported previous findings concerning increases in self-reports of motivation and enhanced test performances in testing situations with consequences. The motivation subscores of Importance and Effort were found to be useful, and for some of the hypotheses the two scores behaved differently and in accord with expectations concerning the construct and context. The effect sizes observed for motivation and performance in the essay format compared to the multiple-choice were among the largest obtained in the study.

Principalization of ideals on toroidal orbifolds

Given an ideal $\mathcal I$ on a variety $X$ with toroidal singularities, we produce a modification $X' \to X$, functorial for toroidal morphisms, making the ideal monomial on a toroidal stack $X'$. We do this by adapting the methods of [W{\l}o05], discarding steps which become redundant. We deduce functorial resolution of singularities for varieties with logarithmic structures. This is the first step in our program to apply logarithmic desingularization to a morphism $Z \to B$, aiming to prove functorial semistable reduction theorems.
Helicobacter pylori cytotoxin-associated gene A protein among adult dyspeptic patients in South-western Nigeria

cagA gene, a marker for the cag pathogenicity island (CagPAI) and a virulent factor in Helicobacter pylori infection codes for 120 to 145 kDa protein that is associated with cytotoxin production and more severe clinical outcomes. The aim of this study was to determine whether any correlation exists between H. pylori CagA protein and the endoscopic findings among dyspeptic patients from South-western, Nigeria and also to investigate the evolutionary relationships among H. pylori cagA gene with the GenBank strains. A total of one hundred and twenty four H. pylori positive isolates were amplified for the detection of cagA by polymerase chain reaction (PCR) and H. pylori isolates positive for cagA were further evaluated for protein expression using western blotting analysis. Also, DNA sequencing, blasting and phylogenetic analysis were performed on twelve selected isolates positive for cagA. cagA gene was detected in all the 124 samples (100%) and protein expressions of cagA by western blotting analysis was 88.7% (110/124). There was a high prevalence (91.7%) of expressed cagA strains in patients with positive endoscopic lesions than those with normal endoscopic findings (85.7%); however, association was not statistically significant (P>0.05). Also, the expressed cagA had no statistically significant association with all the positive endoscopic findings (P>0.05). Phylogenetic analysis of the selected H. pylori cagA gene showed high similarity with some GenBank strains of western cagA H. pylori. This study shows that CagA is high among dyspeptic patients in Nigeria but with no statistically significant association with the endoscopic findings. Key words: Protein expression, CagA, protein, GenBank, dyspeptic.
DENTAL DISEASE AND ITS CURE: A Review

Oral diseases are major health problems with dental caries and periodontal diseases among the most important preventable global infectious diseases. Oral health influences the general quality of life and poor oral health is linked to chronic conditions and systemic diseases. The association between oral diseases and the oral micro biota is well established. The development of dental caries involves acidogenic and aciduric Gram-positive bacteria (mutans streptococci, lactobacilli and actinomycetes). Periodontal diseases have been linked to anaerobic Gram-negative bacteria (Porphyromonas gingivalis, Actinobacillus, Prevotella and Fusobacterium). Several agents are commercially available these chemicals can alter oral micro biota and have undesirable side-effects such as vomiting, diarrhea and tooth staining. Hence, the search for alternative products continues and natural phytochemicals isolated from plants used as traditional medicines are considered as good alternatives. In this review, plant extracts or phytochemicals that inhibit the growth of oral pathogens, reduce the development of bio films and dental plaque, influence the adhesion of bacteria to surfaces and reduce the symptoms of oral diseases.
Reporting Analyses of Covariance Structures

This contribution is focused on how to write a research paper when structural equation models are being used in empirical work. The main question to be answered is what information should be reported and what results can be deleted without much loss of judgment about the quality of research and the validity of conclusions being made. The major conjecture is that all information should be reported, or referred to, that enables each member of the scientific community, at least in principle, to replicate the analysis as it is published. The recommendations are ordered in the framework of the empirical research cycle. They are meant for authors, in particular students employing structural equation models for their dissertation, as well as for editors and reviewers.
Counteracting Destructive Student Misconceptions of Mathematics

In this article, we ask the question of what it takes for targeted efforts to be reasonably successful in altering students’ misconceptions and unproductive beliefs and ensuing myths about mathematics as a discipline and a school subject and about themselves in relation to mathematics, so as to pave the way for satisfactory learning. We attempt to answer this question through the analysis of three cases of upper secondary school students, who all struggled with mathematics-related difficulties due to myths resulting from misguided beliefs, erroneous proof schemes, or mistaken interpretations of the didactical contract, the three theoretical constructs we employ in the study. We describe how specially educated teachers, so-called “mathematics counsellors”, taking part in a professional development program conducted by the authors, were able, firstly, to identity these students, then to diagnose more precisely the nature of their difficulties, and finally to design targeted interventions in order to assist the students in actually overcoming (parts of) their difficulties and eventually dispelling some of the myths they were influenced by. We further offer an analysis of the elements responsible for the success of these interventions. More precisely, we identify five such elements. Finally, we zoom in on the role and intricate connectedness of the three theoretical constructs mentioned above.
Lawrence Berkeley National Laboratory Recent Work Title Genomic differentiation among wild cyanophages despite widespread horizontal gene transfer Permalink

Background: Genetic recombination is a driving force in genome evolution. Among viruses it has a dual role. For genomes with higher fitness, it maintains genome integrity in the face of high mutation rates. Conversely, for genomes with lower fitness, it provides immediate access to sequence space that cannot be reached by mutation alone. Understanding how recombination impacts the cohesion and dissolution of individual whole genomes within viral sequence space is poorly understood across double-stranded DNA bacteriophages (a.k.a phages) due to the challenges of obtaining appropriately scaled genomic datasets. Results: Here we explore the role of recombination in both maintaining and differentiating whole genomes of 142 wild double-stranded DNA marine cyanophages. Phylogenomic analysis across the 51 core genes revealed ten lineages, six of which were well represented. These phylogenomic lineages represent discrete genotypic populations based on comparisons of intraand interlineage shared gene content, genome-wide average nucleotide identity, as well as detected gaps in the distribution of pairwise differences between genomes. McDonald-Kreitman selection tests identified putative niche-differentiating genes under positive selection that differed across the six well-represented genotypic populations and that may have driven initial divergence. Concurrent with patterns of recombination of discrete populations, recombination analyses of both genic and intergenic regions largely revealed decreased genetic exchange across individual genomes between relative to within populations. Conclusions: These findings suggest that discrete double-stranded DNA marine cyanophage populations occur in nature and are maintained by patterns of recombination akin to those observed in bacteria, archaea and in sexual eukaryotes.
The success of extragalactic infrared interferometry: from what we have learned to what to expect

Infrared interferometry has lead to a breakthrough in the investigation of Active Galactic Nuclei (AGN) by allowing to resolve structures on sizes of less than a few parsecs in nearby galaxies. Measurements in the nearinfrared probe the innermost, hottest dust surrounding the central engine and the interferometrically determined sizes roughly follow those inferred from reverberation measurements. Interferometry in the mid-infrared has revealed parsec-sized, warm dust distributions with a clear two component structure: a disk-like component and polar emission – challenging the long-standing picture of the “dusty torus”. New beam combiners are starting to resolve the kinematic structure of the broad line region and are expected to provide true images of the dust emission. Nevertheless, most AGN will remain only marginally resolved by current arrays and next generation facilities, such as the Planet Formation Imager (PFI), will be required to fully resolve out larger samples of AGN.
Imprints of relativistic effects on the asymmetry of the halo cross-correlation function: from linear to non-linear scales

The apparent distribution of large-scale structures in the universe is sensitive to the velocity/potential of the sources as well as the potential along the line-of-sight through the mapping from real space to redshift space (redshift-space distortions, RSD). Since odd multipoles of the halo cross-correlation function vanish when considering standard Doppler RSD, the dipole is a sensitive probe of relativistic and wide-angle effects. We build a catalogue of ten million haloes (Milky-Way size to galaxy-cluster size) from the full-sky light-cone of a new "RayGalGroupSims" N-body simulation which covers a volume of ($2.625~h^{-1}$Gpc)$^3$ with $4096^3$ particles. Using ray-tracing techniques, we find the null geodesics connecting all the sources to the observer. We then self-consistently derive all the relativistic contributions (in the weak-field approximation) to RSD: Doppler, transverse Doppler, gravitational, lensing and integrated Sachs-Wolfe. It allows us, for the first time, to disentangle all contributions to the dipole from linear to non-linear scales. At large scale, we recover the linear predictions dominated by a contribution from the divergence of neighbouring line-of-sights. While the linear theory remains a reasonable approximation of the velocity contribution to the dipole at non-linear scales it fails to reproduce the potential contribution below $30-60~h^{-1}$Mpc (depending on the halo mass). At scales smaller than $\sim 10~h^{-1}$Mpc, the dipole is dominated by the asymmetry caused by the gravitational redshift. The transition between the two regimes is mass dependent as well. We also identify a new non-trivial contribution from the non-linear coupling between potential and velocity terms.
Burden of Chronic Low Back Pain with a Neuropathic Pain Component: Retrospective Chart Review and Cross-sectional Survey among Adults Seeking Treatment in the United States

Background Chronic low back pain (CLBP) is highly prevalent, and between 35% and 55% of individuals with CLBP suffer from a neuropathic pain component (CLBP-NeP). Limited data on the economic and patient burden in this CLBP subgroup have been published. Methods This observational study aimed to characterize burden among CLBP-NeP subjects (n=106) recruited during routine physician visits in the United States. Subjects completed a questionnaire to capture pain severity, function, health status, sleep, anxiety/depression, lost productivity, demographics, employment status, and out-of- pocket expenses. Investigators completed a 6-month retrospective chart review to capture clinical characteristics and CLBP-NeP-related healthcare resource use. Based on average pain severity scores, subjects were stratified into mild, moderate, and severe pain groups. Summary statistics were calculated, and differences across severity groups were evaluated. Results Subjects’ mean (SD) age was 54.1 (11.9) years; 57.5% were female. Most subjects had at least one comorbidity (87.7%); common comorbidities included sleep disturbance/insomnia [58.5%], depressive symptoms [51.9%], headache/migraine [46.2%], and anxiety [45.3%]. Mean (SD) pain severity score was 6.0 (1.77). Outcomes were worse among subjects with greater pain for health status, function, and sleep. Overall, 23.6% of subjects were employed for pay; 32.1% reported being disabled due to CLBP-NeP. Among those employed, lost productivity due to CLBP-NeP (62.3% overall work impairment) was substantial. Nearly all (98.1%) subjects were prescribed one or more medications for CLBP-NeP, including opioids (81.1%), muscle relaxants (33.0%), and antiepileptics (28.3%). Mean adjusted annualized direct and indirect costs per subject were $8,305 and $30,496 (mild), $10,189 and $26,428 (moderate), and $11,880 and $25,051 (severe), respectively, with no significant differences observed. Conclusions Patient and economic CLBP-NeP burden is high despite active management. Sub-optimal outcomes were associated with greater pain severity. Findings point to unmet need and indicate CLBP-NeP burden is experienced in terms of poor function and lost productivity.
Decentralization or Fiscal Autonomy? What Does Really Matter? Effects on Growth and Public Sector Size in European Transition Countries

This paper examines the importance of fiscal autonomy in the analysis of decentralization. Using new data published by the OECD (2001 and 2002), it reproduces several indicators and proposes new measures of decentralization that take into consideration su-bnational governments'autonomy over their revenues. Two models are reproduced: Davoodi and Zou (1998) on decentralization and economic growth,and Oates (1985), on decentralization and public sector size. Some evidence suggests that fiscal autonomy positively affects economic growth. Also, it seems to affect the size of the state, but evidence on this relation is limited. Despite some statistical weaknesses, there are sufficient indications to argue that sub-national governments'fiscal autonomy should be a major concern when measuring decentralization.
The Informativeness of Dividends and Associated Tax Credits

This paper investigates the informativeness of dividends and the associated tax credits with respect to earnings persistence. After confirming that dividend-paying firms have more persistent earnings than non-dividend-paying firms, we show that the taxation status of the dividend is also important. Firms that pay dividends with a full tax credit attached have significantly more persistent earnings than firms that pay dividends which carry no associated tax credit. Consistent with higher levels of tax credits identifying more mature firms, those paying dividends with full tax credits have significantly less persistent losses than firms that pay dividends with only partial tax credits. Further, market pricing tests confirm that the incremental information in dividends and tax credits contributes to reductions in market mispricing of the persistence of earnings and earnings components. Our results are robust to alternative model specifications and controlling for dividend size and firm age.
D ec 2 01 7 Fair mixing : the case of dichotomous preferences

Agents vote to choose a fair mixture of public outcomes; each agent likes or dislikes each outcome. We discuss three outstanding voting rules. The Conditional Utilitarian rule, a variant of the random dictator, is Strategyproof and guarantees to any group of like-minded agents an influence proportional to its size. It is easier to compute and more efficient than the familiar Random Priority rule. Its worst case (resp. average) inefficiency is provably (resp. in numerical experiments) low if the number of agents is low. The efficient Egalitarian rule protects similarly individual agents but not coalitions. It is Excludable Strategyproof : I do not want to lie if I cannot consume outcomes I claim to dislike. The efficient Nash Max Product rule offers the strongest welfare guarantees to coalitions, who can force any outcome with a probability proportional to their size. But it fails even the excludable form of Strategyproofness.
