The Effect of Three Techniques for Teaching English Idioms to Iranian TEFL Undergraduates

The present study investigated the effect of using picture, Persian translation equivalent (L1), and English definition (L2) on the learning of 20 decomposable and nondecomposable idioms by 68 Iranian TEFL undergraduates. The focus was on learning both meaning as well as form of the idioms. The idioms were given to the participants to translate into Persian three weeks before the experiment to ensure the participants’ unfamiliarity of the idioms. The idioms that were known even by one student were crossed out. Each group of the participants received the instruction in 3 sessions (about 7 idioms each session), and reviewed them in the fourth. The participants received 2 recognition tests (one on form and the other on meaning of the L2 idioms) in the form of multiple-choice in the fifth session, and the same recognition as well as 2 production tests in the form of fill-in-the-blanks 3 weeks later (first on form and then on meaning). The delayed posttests were given in 2 consecutive sessions: first, the production and then the recognition. The findings showed that the picture group outperformed the other groups in all situations. However, a significant outperformance of L1 group over L2 group was observed for decomposable idioms in the first posttest regarding form. The results suggest the pedagogical value of pictures for the teaching of meaning and form of decomposable idioms
Extreme Response Style and Acquiescence among Hispanics

Secondary analyses were carried out with four large data sets that included responses by Hispanics (N = 1,908) and by non-Hispanic Whites (N = 14,425). Results are fairly consistent in showing that Hispanics prefer extreme responses to a greater extent than non-Hispanic Whites. In general, Hispanics prefer to agree with a given item more than non-Hispanic Whites. Two significant variables seem to affect the rate at which these response styles are chosen. First, the level of acculturation among Hispanics affects the level of extreme and acquiescent responses so that as Hispanics acculturate they tend to choose these types of response less frequently. The less educated respondents (less than 12 years of formal education) tend to make more extreme choices than the more highly educated (those with at least a secondary education). Gender does not affect these response sets in a consistent fashion.

An investigation into how the undergraduate mathematics topic of sibling curves of functions can be developed and used for student enrichment

The aim of this research study is to investigate how undergraduate mathematics can be enhanced through research and how this enriched content can be exploited for the enrichment of academically stronger students. The study offers a unique blend of mathematical and educational research. In the first part of the study a problem stemming from teaching the undergraduate topic of complex numbers, namely on how to represent the zeroes of functions, particularly polynomials, is researched. The notion of sibling curves ([51], [52]) offers an elegant and natural way to represent the zeroes of a polynomial, which is explored and expanded in this thesis. A library of sibling curves for well-known functions is developed and presented. Significant research results are that every polynomial of degree n has n sibling curves. This result gives a more geometric interpretation of the roots of a polynomial than the Fundamental Theorem of Algebra. I then focus on quadratic polynomials with complex coefficients and prove that, although the siblings are not always parabolas, the two sibling curves are always congruent and that they lie on a hyperbolic paraboloid determined by the coefficients of the polynomial. Some of these results are reported on in [115]. The second part of the study centres on utilising the researched knowledge on sibling curves for student enrichment. A group of first year students were guided through a number of designed activities using an inquiry-based learning approach to explore polynomials, complex numbers and ultimately sibling curves. Implementation of the programme as well as experiences are reported on, following a research approach of evaluation research. Student as well as facilitator experiences, discoveries and learning curves were captured in order to analyse perspectives. Results show that there is a need to stimulate and challenge academically strong undergraduate students. The study further shows that all the participants of this enrichment programme benefited from this experience. The students were engaged with the work and had the opportunity to delve deeper into the mathematical topic while sharpening their problem solving skills. I, as facilitator, had the opportunity to interact closely with academically strong students and experience their needs first hand, which added a new dimension to my teaching. This research ii © University of Pretoria also demonstrates how enrichment programmes can be a vehicle to expose enriched content to academically strong students. The dual value of the study is that it adds not only to the knowledge base of complex number theory, but also to the body of reported experiences on student enrichment in undergraduate mathematics teaching. It is envisaged that research findings reported on in this study will lead to an increased focus on student enrichment at tertiary level. This study exposes this element of teaching academically strong students and offers possible avenues of challenging these students.
Interim and Long-Run Dynamics in the Evolution of Conventions

We characterize transitions between stochastically stable states and relative ergodic probabilities in the theory of the evolution of conventions. We give an application to the fall of hegemonies in the evolutionary theory of institutions and con ict and illustrate the theory with the fall of the Qing Dynasty and rise of Communism in China.

Journalists’ victimization experiences and fear of crime at the workplace: Results of a questionnaire survey from Greece and Cyprus

Using a representative sample of 635 active professional journalists, this study is one of the first to examine the prevalence of non-lethal workplace victimization experiences and the extent of fear of crime among journalists. The results indicated a relatively high prevalence of physical victimization, an exceptionally high prevalence of psychological abuse and an average prevalence of property victimization among professional journalists. Additionally, it was found that journalists overall had relatively low levels of fear of crime at work. The analysis also revealed the sociodemographic and employment characteristics of professional journalists who were more closely associated with different types of victimization and fear of crime at work.
Characterization of a donor mitochondrial DNA transmission bottleneck in nuclear transfer derived cow lineages

In embryos derived by nuclear‐transfer (NT), fusion of donor cells with recipient oocytes resulted in varying patterns of mitochondrial DNA (mtDNA) transmission in NT animals. Distribution of donor cell mtDNA (D‐mtDNA) found in offspring of NT‐derived founders may also vary from donor cell and host embryo heteroplasmy to host embryo homoplasmy. Here we examined the transmission of mtDNA from NT cows to G1 offspring. Eleven NT founder cows were produced by fusion of enucleated oocytes (Holstein/Japanese Black) with Jersey/ Holstein oviduct epithelial cells, or Holstein/Japanese Black cumulus cells. Transmission of mtDNA was analyzed by PCR mediated single‐strand conformation polymorphism of the D‐loop region. In six of seven animals sampled postmortem, heteroplasmy were detected in various tissues, while D‐mtDNA could not be detected in blood or hair samples from four live animals. The average proportion of D‐mtDNA detected in one NT cow was 7.6%, and those in other cows were <5%. Heteroplasmic NT cows (n = 6) generated a total 12 G1 offspring. Four of 12 G1 offspring exhibited high percentages of D‐mtDNA populations (range 17–51%). The remaining eight G1 offspring had slightly or undetectable D‐mtDNA (<5%). Generally, a genetic bottleneck in the female germ‐line should favor a homoplasmic state. However, proportions of some G1 offspring maintained heteroplasmy with a much higher percentage of D‐mtDNA than their NT dams, which may also reflect a segregation distortion caused by the proposed mitochondrial bottleneck. These results demonstrate that D‐mtDNA in NT cows is transmitted to G1 offspring with varying efficiencies. Mol. Reprod. Dev. 75: 759–765, 2008. © 2007 Wiley‐Liss, Inc.
An Elicitation Study on Gesture Attitudes and Preferences Towards an Interactive Hand-Gesture Vocabulary

With the introduction of new depth sensing technologies, interactive hand-gesture devices are rapidly emerging. However, the hand-gestures used in these devices do not follow a common vocabulary, making certain control command device-specific. In this paper we present an initial effort to create a standardized interactive hand-gesture vocabulary for the next generation of television applications. We conduct a user-elicitation study using a survey in order to define a common vocabulary for specific control commands, such as Volume up/down, Menu open/close, etc. This survey is entirely user-oriented and thus it has two phases. In the first phase, we ask open questions about specific commands. In the second phase, we use the answers suggested from the first phase to create a multiple choice questionnaire. Based on the results from the survey, we study the gesture attitudes and preferences between gender groups, and between age groups with a quantitative and qualitative statistical analysis. Finally, the hand-gesture vocabulary is derived after applying an agreement analysis on the user-elicited gestures. The proposed methodology for gesture set design is comparable with existing methodologies and yields higher agreement levels than relevant user-elicited studies in the field.
Coral Reef Calcification and Production After the 2016 Bleaching Event at Lizard Island, Great Barrier Reef

Severe coral bleaching events have affected the GBR causing massive losses of hard coral cover. Here we use ﬂ ow respirometry approaches to assess coral reef net ecosystem calci ﬁ cation (NEC) and net ecosystem production following the 2015/2016 bleaching event at Lizard Island in the northern Great Barrier Reef, a heavily impacted area. Previous studies conducted in 2008 and 2009 (Silverman et al., 2014, http://10.1016/j.gca.2014.09.011) were used as preimpact data. Lagrangian and Eulerian approaches provided varied results. Estimated NEC (29.1 to 137.7 mmol m − 2 day − 1 ) and NEP ( − 876.7 to 50.5 mmol m − 2 day − 1 ) rates in 2016 were highly sensitive to assumptions about reef water residence times and oceanic end ‐ member concentrations. Replicating the methodology used for the 2008 and 2009 study resulted in postbleaching NEC in 2016 of 32 ± 10.8 mmol m − 2 day − 1 , 40% – 46% lower than prebleaching estimates in 2008 (61 ± 12 mmol m − 2 day − 1 ) and 2009 (54 ± 13 mmol m − 2 day − 1 ). The slopes of the total alkalinity versus dissolved inorganic carbon plot decreased from ~ 0.3 in 2008 and 2009 to 0.1 in 2016, indicating elevated organic production and a shift in community function. Changes in NEC relative to the previous study were not driven by changing Ω arag . Coral cover shifted from 8.3% and 7.1% in 2008 and 2009 to 3.0% in 2016. We demonstrate a clear decrease in coral reef NEC following bleaching and highlight that subtle assumptions/methodological differences may create bias in the interpretation of results. Therefore, comparing coral reef metabolism data sets and predicting long ‐ term coral reef calci ﬁ cation based on existing short ‐ term data sets needs to be done with care. on the reef ﬂ at current meter only using current velocities rather than transport to estimate transit times and an average DIC and TA concentration at the reef crest obtained during daytime only. The EU2 assumptions represent the closest match to the methodology of earlier work (Silverman et al., 2014), allowing for more reasonable predisturbance and post disturbance comparisons.
Development and validation of an instrument to assess secondary school students’ perceptions of assessment tasks

Research aimed at developing and validating an instrument to assess secondary school students’ perceptions of assessment tasks was conducted. Following a review of literature, a five‐scale instrument of 40 items was trialled with a sample of 658 science students in 11 English secondary schools. Based on internal consistency reliability data and exploratory factor analysis, refinement decisions resulted in a five‐scale instrument called the Perceptions of assessment tasks inventory (PATI). The scales of the PATI are Congruence with planned learning, Authenticity, Student consultation, Transparency and Diversity.
Hope and Siege: The Experiences of Parents Whose Children Were Placed in Residential Care

This qualitative study focused on research into the impact on parents of children's out-of-home placement. Twelve couples (24 parents) were interviewed. Three major themes emerged: (a) parents' perception of out-of-home placement as necessary because of children's destructive behavior and parents' victimhood; (b) parents' acknowledgment of positive changes in the child and the family, their pain surrounding the child's pressurizing to return home and fear of regression if this should come about; (c) guilt as a major emotion that impacts their couple relationship. The study results are evaluated in the context of research on parents' reactions to children's removal from home.

An Analysis and Synthesis of DLOQ-Based Learning Organization Research

The problem The development of the Dimensions of the Learning Organization Questionnaire (DLOQ) has been contributing to the research on the learning organization both academically and practically. However, scholarly use of the DLOQ has been greater in the human resource development (HRD)-related disciplines. To encourage wider use, HRD researchers should acknowledge and reflect on the limitations of the extant literature and put an effort into providing theoretical foundations for how the DLOQ could be extensively used in several related disciplines. The Solution This study reviews comprehensive studies on the DLOQ and provides an underlying theoretical rationale for utilizing the DLOQ in multiple disciplines. In addition, future research recommendations are provided for enriching the learning organization studies using the DLOQ in HRD discipline. The Stakeholders Stakeholders for this article include HRD scholars, practitioners, and scholar-practitioners interested in the DLOQ-based theory, research, and practice.
Divergent Response of Leaf Coloring Seasons to Temperature Change in Northern China over the Past 50 Years

Autumn phenology plays a critical role in terrestrial ecosystem circulations. However, the changes in autumn phenology and their correlation with temperature remain uncertain because mean temperature alone was not able to determine the changes in autumn phenology at various sites. Here, the leaf coloring season (LCS) was defined as the period when the leaves of more than half of the species had recognized changes in color. We systematically studied the changes in peak, start, end, and duration of LCS and their correlations with five temperature parameters (mean temperature, accumulated cold temperature, day temperature, night temperature, and temperature difference between day and night) in four periods. Similarly to previous findings, the start date of LCS advanced and the end of LCS delayed over the past 50 years, which consequently led to a lengthened duration of LCS in Xi’an, Harbin, Minqin, and Shenyang. In general, the rise in mean temperature, day temperature, and night temperature would delay the peak, start, and end of LCS and lengthen the duration of LCS in most cases. We also proved that the changes in LCS metrics not only could completely be explained by mean temperature but also were influenced by day temperature, night temperature, temperature difference, and even other climatic factors such as precipitation, at different sites.
Unilateral lumbar spondylolysis on radiography and MRI: emphasis on morphologic differences according to involved segment.

OBJECTIVE The objective of our study was to retrospectively compare the radiography and MRI findings of unilateral spondylolysis in the upper lumbar segment and in the lower lumbar segment and to consider how these radiologic findings can be applied in the diagnosis of unilateral spondylolysis. MATERIALS AND METHODS Thirty patients with unilateral lumbar spondylolysis were categorized into one of two groups according to the lumbar levels involved with pars interarticularis defects: group A (L1, L2, and L3) or group B (L4 and L5). On radiographs, we evaluated contour bulging of the affected pars interarticularis, reactive sclerosis in the contralateral pedicle, anterolisthesis of the involved vertebra, and deviation of the spinous process. On MRI, we assessed pseudoarticulation of the pars interarticularis defect, uneven distribution of posterior epidural fat, the interspinous distance between adjacent segments, facet and disk degeneration in adjacent segments, and other anomalous changes. RESULTS Among the 63 patients with unilateral spondylolysis, the upper lumbar segment was involved in 29 and the lower lumbar segment, in 34. Group A often displayed contour bulging of the affected pars interarticularis, reactive sclerosis of the contralateral pedicle, and contralateral deviation of the spinous process, all of which were easily detectable on radiography. Group B frequently showed anterolisthesis, pseudoarticulation of the pars interarticularis defect, adjacent facet-disk degeneration, and other anomalous changes that were well observed on MRI. CONCLUSION Unilateral lumbar spondylolysis displayed radiologic differences in morphology of the isthmic defect itself and in ancillary findings of the adjacent structures based on the segment involved. Recognition of different ancillary features of unilateral spondylolysis with the use of a feasible diagnostic tool can be helpful for the diagnosis of cases in which a direct sign of isthmic defect is equivocal.
Expected Subjective Value Theory (ESVT): A Representation of Decision Under Risk and Certainty

We present a descriptive model of choice that incorporates neurobiological constraints, representational structures and costs into a traditional economic framework. An individual's behavior is fully described by two, in principle observable, primitives: an individual's neural/mental capacity and an endogenous rational expectation. The model captures the phenomena captured by Prospect Theory: reflection in risk attitudes and loss aversion, but unlike Prospect Theory accounts for individual heterogeneity in each and employs fewer parameters. Our theory provides an alternative explanation for endowment effect and makes a series of novel predictions amenable to future testing.
Phase II trial of single-agent temsirolimus (CCI-779) for relapsed mantle cell lymphoma.

PURPOSE Mantle cell lymphoma (MCL) is characterized by a t(11;14) resulting in overexpression of cyclin D1 messenger RNA. This study tested whether temsirolimus (previously known as CCI-779), an inhibitor of the mammalian target of rapamycin kinase that regulates cyclin D1 translation, could produce tumor responses in patients with MCL. PATIENTS AND METHODS Patients with relapsed or refractory MCL were eligible to receive temsirolimus 250 mg intravenously every week as a single agent. Patients with a tumor response after six cycles were eligible to continue drug for a total of 12 cycles or two cycles after complete remission, and were then observed without maintenance. RESULTS Thirty-five patients were enrolled and were assessable for toxicity; one patient had MCL by histology but was cyclin D1 negative and was ineligible for efficacy. The median age was 70 years (range, 38 to 89 years), 91% were stage 4, and 69% had two or more extranodal sites. Patients had received a median of three prior therapies (range, one to 11), and 54% were refractory to the last treatment. The overall response rate was 38% (13 of 34 patients; 90% CI, 24% to 54%) with one complete response (3%) and 12 partial responses (35%). The median time-to-progression in all patients was 6.5 months (95% CI, 2.9 to 8.3 months), and the duration of response for the 13 responders was 6.9 months (95% CI, 5.2 to 12.4 months). Hematologic toxicities were the most common, with 71% (25 of 35 patients) having grade 3 and 11% (four of 35 patients) having grade 4 toxicities observed. Thrombocytopenia was the most frequent cause of dose reductions but was of short duration, typically resolving within 1 week. CONCLUSIONS Single-agent temsirolimus has substantial antitumor activity in relapsed MCL. This study demonstrates that agents that selectively target cellular pathways dysregulated in MCL cells can produce therapeutic benefit. Further studies of this agent in MCL and other lymphoid malignancies are warranted.
