Assessment policies, curricular directives, and teacher agency: quandaries of EFL teachers in Inner Mongolia

In the debate over English language teaching approaches and methods, the influence of examinations on classroom pedagogy and the nature of these examinations are critical considerations for teachers. In the Inner Mongolian context, as for all China, examinations reflect traditional conceptions of teaching and learning, classroom teaching conditions such as class sizes, and the English-as-a-foreign language setting. In this situation, decisions about classroom pedagogy and objectives and whether teaching focuses on test-taking rather than on the learning of language go to the core of teacher agency. In this paper we foreground the struggles and dilemmas experienced by English language teachers in Inner Mongolia in attempts to exercise agency amidst the instructional demands of an exam-oriented community, and a misalignment created by an exam remaining centered on discrete skills rather than students' proficiency in applying ranging uses of the language they are learning. These conditions are now located within New English Syllabus expectations are that teachers will implement their knowledge of educational theories and of current English teaching methodology to create opportunities for more broadly based learning and proficiency. © 2014 © 2014 Taylor & Francis.

A tailored, supportive care intervention using systematic assessment designed for people with inoperable lung cancer: a randomised controlled trial

Objective : People with inoperable lung cancer experience higher levels of distress, more unmet needs and symptoms than other cancer patients. There is an urgent need to test innovative approaches to improve psychosocial and symptom outcomes in this group. This study tested the hypothesis that a tailored, multidisciplinary supportive care programme based on systematic needs assessment would reduce perceived unmet needs and distress and improve quality of life.

Methods : A randomised controlled trial design was used. The tailored intervention comprised two sessions at treatment commencement and completion. Sessions included a self-completed needs assessment, active listening, self-care education and communication of unmet psychosocial and symptom needs to the multidisciplinary team for management and referral. Outcomes were assessed with the Needs Assessment for Advanced Lung Cancer Patients, Hospital Anxiety and Depression Scale, Distress Thermometer and European Organization of Research and Treatment of Cancer Quality of Life Q-C30 V2.0.

Results : One hundred and eight patients with a diagnosis of inoperable lung or pleural cancer (including mesothelioma) were recruited from a specialist facility before the trial closed prematurely (original target 200). None of the primary contrasts of interest were significant (all p > 0.10), although change score analysis indicated a relative benefit from the intervention for unmet symptom needs at 8 and 12 weeks post-assessment (effect size = 0.55 and 0.40, respectively).

Conclusion : Although a novel approach, the hypothesis that the intervention would benefit perceived unmet needs, psychological morbidity, distress and health-related quality of life was not supported overall.

Effects of variation in wool fiber curvature and yarn hairiness on sensorial assessment of knitted fabrics

Previous investigations have shown that prickle discomfort sensations of wool fabrics are primarily determined by the mean fiber diameter of the wool. It is also known that differences in wool fiber curvature (crimp) affect softness of handle of greasy wool and of wool textiles. In a replicated experiment, we investigated if wearers could detect the effect of using 17 µm superfine wool of low (74°/mm) or high (114°/mm) fiber curvature, and when the wools were blended with 17 µm cashmere (fiber curvature 49°/mm) in differing proportions, on four comfort sensations. Eight single jersey knitted fabrics were assessed under a controlled protocol using forearm sleeves made of the test fabric and a control fabric. Data (37 sensorial assessments of high curvature wool fabrics; 38 sensorial assessments of low curvature wool fabrics) were analyzed using linear mixed model analysis (restricted maximum likelihood), which included fixed effects for wool type and blend ratio and a random effect for participant. The use of a control sleeve fabric reduced variance due to participant effects by providing an anchor for each sensation over time. Wool fiber curvature affected participant assessment of breathability, comfort, feel after exercise (damp/dry) and skin feel (prickly/soft), with preferred values associated with high curvature (crimp) superfine wool. Increasing the proportion of cashmere in fabrics increased skin feel (better assessed softness). Skin feel was strongly associated with the evaluation of the fabrics by the Wool ComfortMeter and with increasing hairiness of yarns.

Validation of the needs assessment for advanced lung cancer patients (NA-ALCP)

Objective: The Needs Assessment for Advanced Cancer Patients (NA-ACP) is a 132-item self-report questionnaire designed to assess the seven needs domains of patients with advanced, incurable cancer. This study aimed to evaluate the short derivative form of that questionnaire with advanced lung cancer patients.

Methods: Item factor loadings, item test–retest data and response distributions were used to retain or reject items from the original NA-ACP scale. This resulted in 38 items being maintained, preserving the original subscales. The response scale was simplified following feedback from patients. 108 people with advanced lung cancer completed the shortened NA-ALCP along with measures of psychological distress (HADS, DT) and quality of life (EORTC QLQ-C30). A-priori predictions were made for divergent and convergent validity.

Results: Internal consistency coefficients were satisfactory for six of seven subscales, range 0.71–0.95. Correlations between NA-ALCP and HADS, DT and EORTC-QLQ-C30 provided support for 11 of the 22 divergent (r = 0.13–0.27) and convergent predictions (r = 0.45–0.71).

Conclusions: Subscales of the NA-ALCP demonstrated internal reliability consistent with the original scale. Results provided supporting evidence for divergent and convergent validity. This study indicates that the NA-ALCP is psychometrically robust, easily understood and one-quarter the length of the original version

Dynamic weight-bearing assessment of pain in knee osteoarthritis: a reliability and agreement study

Purpose: To evaluate the reliability, agreement and smallest detectable change in a measurement instrument for pain and function in knee osteoarthritis; the Dynamic weight-bearing Assessment of Pain (DAP). Methods: The sample size was set to 20 persons, recruited from the outpatient osteoarthritis clinic at Frederiksberg Hospital, Copenhagen. Two physiotherapists tested all participants during two visits; at the first visit, one single DAP (including four scores) was conducted by rater one; at the second visit, DAP was conducted by both raters one and two in randomized order with concealed allocation. The time interval was approximately 1.5 h. Measurement error was estimated by standard error of measurement (SEM). The intra- and inter-rater reliability was estimated by Intra-class Correlation Coefficients for agreement based on a two-way ANOVA with random effects (single measures ICC 2.1). Smallest detectable change (SDC) and limits of agreement were calculated.Results: The pain score showed excellent reliability in terms of ICC (intra-rater 0.93, CI 0.83–0.97, inter-rater 0.91, CI 0.78–0.96), low SEM (intra-rater 0.70, inter-rater 0.86, on a scale from 0 to 10), and acceptable SDC for intra-rater test (1.95). The three knee bend scores all had ICC above 0.50, showing fair-to-good reliability. None of the knee bend scores showed acceptable SEM and SDC. Conclusions: The reproducibility of the DAP pain score meets the demands for use in clinical practice and research. The total knee bend could be useful for motivational purpose in clinical use. Testing of other psychometric properties of the DAP is pending.

Student knowledge: curriculum, assessment and reporting

At a time when national and international high-stakes testing has assumed such prominence, one might begin to wonder about the status of teacher judgement when assessing and reporting on children’s knowledge and skills against the descriptors specified in curriculum standards. Were standardised test results congruent with the judgements that teachers make when reporting on students’ achievement, concern about how one type of judgement might compare with another would perhaps be unwarranted. This article draws on research that has investigated whether standardised assessments in the state of Victoria, Australia are actually comparable with teacher’s judgements about their students’ work to illustrate that discrepancies do exist. These results have been interpreted within an analytical framework that derives from Aristotle’s (350BC/2000) distinction between three types of knowledge, namely epistemic, technical and phronetic knowledge.

Cultural influence on global assessment of higher education service quality: The case of Central Queensland University, Australia

© 2014 by IGI Global. All rights reserved. This study compares students' cultural influence on global assessment of higher education service quality. In particular, this study surveyed the full-time students (that is at least 24 credit points of study in a semester) studying at the Central Queensland University (CQU), Australia. CQU has ten campuses and is one of the largest universities in Australia, with more than 14,000 students, in which 3,000 students are enrolled as full-time students and 11,000 as part-time students. An online survey was undertaken, and 227 responses from full-time students were returned for data analysis. Exploratory factor analysis and confirmatory factor analysis were performed to determine valid and reliable dimensions of perceived service quality. Tests of differences such as ANOVA and t-test were conducted to examine the differences of perceived service quality in terms of four cultural dimensions; namely, power distance, individualism, uncertainty avoidance, and masculinity. Findings show that different cultures perceive service quality differently; especially administrative service quality and physical facilities service quality.

Assessment of bond strength in CFRP retrofitted beams under marine environment

Carbon fibre reinforced polymer (CFRP) sheet has gained its popularity to retrofit civil structures which is bonded externally, typically on the soffit of a beam. In this study, the bond between carbon fibre reinforced polymer (CFRP) and concrete is improved by modifying the property of commercial epoxy and compared against normal epoxy. The deterioration in bond strength was produced by placing the beam into salt water under wet dry cycles. Also, a model is proposed to determine the bond strength from flexural test and compared against the available bond strength models which are typically obtained from pull out test. This proposed model shows promising results in terms of predicting the bond strength from flexural test. In addition, a strength reduction factor is introduced to incorporate the effect of wet dry cycles to predict the long term behaviour. It is found that the modified epoxy enhance the ductile property and bond strength.

A BDI-based approach for the assessment of driver's decision-making in commuter scenarios

The rapid growth of urban areas has a significant impact on traffic and transportation systems. New management policies and planning strategies are clearly necessary to cope with the more than ever limited capacity of existing road networks. The concept of Intelligent Transportation System (ITS) arises in this scenario; rather than attempting to increase road capacity by means of physical modifications to the infrastructure, the premise of ITS relies on the use of advanced communication and computer technologies to handle today’s traffic and transportation facilities. Influencing users’ behaviour patterns is a challenge that has stimulated much research in the ITS field, where human factors start gaining great importance to modelling, simulating, and assessing such an innovative approach. This work is aimed at using Multi-agent Systems (MAS) to represent the traffic and transportation systems in the light of the new performance measures brought about by ITS technologies. Agent features have good potentialities to represent those components of a system that are geographically and functionally distributed, such as most components in traffic and transportation. A BDI (beliefs, desires, and intentions) architecture is presented as an alternative to traditional models used to represent the driver behaviour within microscopic simulation allowing for an explicit representation of users’ mental states. Basic concepts of ITS and MAS are presented, as well as some application examples related to the subject. This has motivated the extension of an existing microscopic simulation framework to incorporate MAS features to enhance the representation of drivers. This way demand is generated from a population of agents as the result of their decisions on route and departure time, on a daily basis. The extended simulation model that now supports the interaction of BDI driver agents was effectively implemented, and different experiments were performed to test this approach in commuter scenarios. MAS provides a process-driven approach that fosters the easy construction of modular, robust, and scalable models, characteristics that lack in former result-driven approaches. Its abstraction premises allow for a closer association between the model and its practical implementation. Uncertainty and variability are addressed in a straightforward manner, as an easier representation of humanlike behaviours within the driver structure is provided by cognitive architectures, such as the BDI approach used in this work. This way MAS extends microscopic simulation of traffic to better address the complexity inherent in ITS technologies.

Graph analysis of verbal fluency test discriminate between patients with Alzheimer’s disease, Mild Cognitive Impairment and normal elderly controls

Verbal fluency is the ability to produce a satisfying sequence of spoken words during a given time interval. The core of verbal fluency lies in the capacity to manage the executive aspects of language. The standard scores of the semantic verbal fluency test are broadly used in the neuropsychological assessment of the elderly, and different analytical methods are likely to extract even more information from the data generated in this test. Graph theory, a mathematical approach to analyze relations between items, represents a promising tool to understand a variety of neuropsychological states. This study reports a graph analysis of data generated by the semantic verbal fluency test by cognitively healthy elderly (NC), patients with Mild Cognitive Impairment – subtypes amnestic(aMCI) and amnestic multiple domain (a+mdMCI) - and patients with Alzheimer’s disease (AD). Sequences of words were represented as a speech graph in which every word corresponded to a node and temporal links between words were represented by directed edges. To characterize the structure of the data we calculated 13 speech graph attributes (SGAs). The individuals were compared when divided in three (NC – MCI – AD) and four (NC – aMCI – a+mdMCI – AD) groups. When the three groups were compared, significant differences were found in the standard measure of correct words produced, and three SGA: diameter, average shortest path, and network density. SGA sorted the elderly groups with good specificity and sensitivity. When the four groups were compared, the groups differed significantly in network density, except between the two MCI subtypes and NC and aMCI. The diameter of the network and the average shortest path were significantly different between the NC and AD, and between aMCI and AD. SGA sorted the elderly in their groups with good specificity and sensitivity, performing better than the standard score of the task. These findings provide support for a new methodological frame to assess the strength of semantic memory through the verbal fluency task, with potential to amplify the predictive power of this test. Graph analysis is likely to become clinically relevant in neurology and psychiatry, and may be particularly useful for the differential diagnosis of the elderly.

Assessment of estrogenic, mutagenic and antimutagenic activity of nemorosone

Currently, a wide range of research involving natural products is focused on the discovery of new drugs in many different therapeutic areas. A great number of the synthetic compounds on the market were derived from natural products, especially plants. Nemorosone is the major constituent of the floral resin of Clusia rosea Jacq., Clusiaceae, and in Cuban propolis. In vitro studies have shown cytotoxic activity in this substance against various tumor cell lines, including those resistant to various cytotoxic drugs, whereas it has low cytotoxicity to non-tumoral cells. Therefore, in order to characterize the biological activity of nemorosone, a substance with potential antitumor activity, and in view of preclinical testing of the toxicity of drug candidate compounds, the main aim of this study was to determine the mutagenic and antimutagenic activity of nemorosone by the Ames test, using the strains TA97a, TA98, TA100 and TA102 of Salmonella typhimurium. Secondly, to characterize the estrogenic activity in an experimental recombinant yeast model (Recombinant Yeast Assay) mutagenic activity was observed at in any of the concentrations in any of the test strains. To evaluate the antimutagenic potential, direct and indirect mutagenic agents were used: 4 nitro-o-phenylenediamine (NPD), mitomycin C (MMC) and aflatoxin B1 (AFL). Nemorosone showed moderate antimutagenic activity (inhibition level 31%), in strain TA100 in the presence of AFL, and strong antimutagenic activity in TA102 against MMC (inhibition level 53%). Estrogenic activity was observed, with an EEq of 0.41±0.16 nM at various tested concentrations.
