Behind league tables and ranking systems
Authors: Berbegal-Mirabent Jasmina , Ribeiro-Soriano D. Enrique 
Published: April 2015

Purpose
– The purpose of this paper is to examine the role of university ranking systems as instruments of university quality assessment. Some controversy surrounds the methodology used to compile such instruments. Accordingly, different compilers have adopted different methods to produce these rankings. This study examines to what extent this diversity in methodology is now converging in the context of Spanish university rankings.

Design/methodology/approach
– To conduct this research, a two-step approach was adopted. First, the indicators used in four Spanish rankings were examined. Second, empirical analysis was used to identify differences between university rankings.

Findings
– Results reveal that, despite the vast number and variety of indicators, there is a positive, significant relationship between rankings. Spanish university rankings thus show some degree of convergence.

Social implications
– Because rankings influence behavior and shape institutional decision making, a better understanding of how these assessment tools are devised is essential. Research on these ranking systems therefore offers an important contribution to improving the quality of higher education institutions.

Originality/value
– This paper presents the results of a comprehensive survey of Spanish university rankings. It offers a new perspective of the state of the art of the Spanish university ranking system. The paper also presents a set of managerial implications for improving these benchmarking tools.
This is the sound of one voice: singing to see beyond boundaries in a university community choir
Authors: Monk Sue , Mackinlay Elizabeth 
Published: April 2015

Purpose– The purpose of this paper is to explore their experiences as singers in a community choir called Arrkula (a Yanyuwa word meaning “one voice”) based in the School of Education at the University of Queensland as performance of song, self, social justice and seeing beyond boundaries. Performing at “gigs” inside and outside the university, Arrkula has been singing together since 2011, and despite an environment replete with neo-liberal ideals of individualism, competitiveness and capitalist driven research agendas, at the centre of their song remains a yearning for social connection, equality and renewed consciousness.Design/methodology/approach– The authors take an autoethnographic creative approach and bring performance of song together with their stories and interviews with choir members to link the “secret space” of the rehearsal with the “public space” of staged performances.Findings– The authors’ aim is to think and perform the potential the voice and voices of Arrkula hold in terms of heightening senses of agency, provoking and empowering a pursuit of freedom and transforming lived worlds through song.Originality/value– The value of this paper is the authors’ take up of Maxine Greene’s (2005, p. 38) question, “if we can link imagination to our sense of possibility and our ability to respond to other human beings, can we link it to the making of community as well?” to consider what singing for democracy and difference might mean individually and collectively in the current climate of higher education.
Case writing for collaborative practice in education studies
Authors: Carr Amanda , Gilmore Gwen , Cacciattolo Marcelle 
Published: April 2015

Purpose
– The purpose of this paper is to discuss that in 2012, a small group of teaching staff in a new diploma of Education Studies program came together to critically reflect on teaching approaches that either hindered or encouraged learners to thrive in the transition environment in higher education (HE).

Design/methodology/approach
– This paper reports on the use of case writing as a methodological tool for engaging in reflexive inquiry in a HE cross-faculty setting; it also adds a further dimension to the work of (Burridge et al., 2010). The team used a systematic coding activity, known as “threading,” to unpack over-arching themes that were embedded in each other’s narratives.

Findings
– Throughout the two years of the project, 12 cases were presented on key critical teaching moments that the researchers had experienced. The themes varied and included topics like student reflections on why they found learning challenging, teachers’ mixed emotions about failing students, difficulties for teachers in having to persuade students to read academic texts, teacher/student confrontations and student resilience amidst challenges linked to their personal and student lives.

Social implications
– A central theme to emerge from the research was that complexities arise for teachers when they are faced with learners who are apparently not suited to the career pathway they have signed up for.

Originality/value
– Through using a collaborative practitioner research framework, enunciating concerns were raised and different interpretations of the same incident were shared. The paper concludes that case writing can assist academics to be more informed of teaching approaches that lead to successful learning outcomes.
“I was made to feel very discriminated against as an anglo-saxon”
Authors: Faulkner Julie , Crowhurst Michael 
Published: April 2015

Purpose
– Critical discussion of the social conditions that shape educational thinking and practice is now embedded in accredited teacher education programmes. Beneath beliefs that critique of educational inequality is desirable, however, lie more problematic questions around critical pedagogies, ethics and power. Emotional investments can work to protect habituated ways of thinking, despite attempts to move students beyond their comfort zone. This strategic process can shift attitudes and promote intellectual and emotional growth, but can also produce defensive reactions. This paper, a self-study in relation to an incident in a tertiary education programme, examines how student feedback on content and pedagogy positions teachers and learners. The purpose of this paper is to frame and reframe ways in which learner feedback to critical approaches might be read. The argument examines, through dialogue, the potential of disruptive teaching approaches for recontextualising both learner and teacher response. Such exploration articulates particular tensions and challenges inherent in critical teacher education pedagogies.

Design/methodology/approach
– This is a reflective practitioner piece – involving journaling and the use of dialogue – to explore a critical incident.

Findings
– This is an exploratory piece – the authors explore the workings of tension in critical/poststructural pedagogical work.

Originality/value
– The deployment of dialogue as a method and as a way of presenting key issues is somewhat novel. The paper works through quite complex terrain in an accessible and reasonably clear fashion.
Festival as methodology: the African cultural youth arts festival
Authors: Wright Peter R. , Wakholi Peter M. 
Published: April 2015

Purpose– The purpose this paper is to consider festivals as sites for inquiry and learning.Design/methodology/approach– The research employed a pluralistic approach to the inquiry drawing on critical African-centred pedagogy, participatory action research, and performance as research inquiry. These arts-based research methods allowed insights to be gained in ways that were congruent to the arts and participants who enacted them. In total, 12 young people and six elders of diverse African heritage as well as two artists were participants in the research.Findings– The research revealed that the festival as a research methodology was both dialogic and performative and a rich site for the exploration of identity negotiation. Through these arts-based approaches the aesthetic elements often missed by traditional social science methods were highlighted as key in exploring acculturation socialistaion experiences and deconstructing exclusionist discourses emanating from the dominant culture.Research limitations/implications– The research affirmed the power of multi-modal approaches to research and the importance of evocative discourses in identity exploration and development.Originality/value– This research is the first known attempt to theorise an arts-based festival as a research approach in reference to enculturation and cultural memory.
Shape matters: corolla curvature improves nectar discovery in the hawkmoth Manduca sexta
Authors: Campos Eric O. , Bradshaw Harvey D. , Daniel Thomas L. 
Published: April 2015

Summary

We measured the effects of variation in corolla curvature and nectary aperture radius on pollinator foraging ability using the hawkmoth Manduca sexta and 3D‐printed artificial flowers whose shapes were mathematically specified.

In dimorphic arrays containing trumpet‐shaped flowers and flat‐disc flowers, hawkmoths were able to empty the nectaries of significantly more trumpet‐shaped flowers regardless of nectary aperture size. Interestingly, trumpet‐shaped flowers needed to deviate only slightly from the flat‐disc morphotype in order to significantly increase hawkmoth foraging ability.

Whole‐flower three‐dimensional shape, particularly corolla curvature, has the potential to act as a mechanical guide for M. sexta, further implicating direct flower‐proboscis contact as an important contributor to foraging success during flower handling in hawkmoths.
An assessment of the effects of habitat structure on the scat finding performance of a wildlife detection dog
Authors: Leigh Kellie A. , Dominick Martin 
Published: April 2015

Summary

As threatened species decline in number, they become more difficult to detect and assess, decreasing our ability to make informed conservation management decisions. Wildlife scat detection dogs are a promising non‐invasive survey method for increasing detection rates of these species. However, a complexity of variables can reduce the certainty of this method, which may contribute to low uptake rates by land managers. One of the variables discussed in dog training literature is the potential for habitats with more complex vegetation to inhibit dispersion of target odours, reducing the dog's ability to detect scats.

We undertook the first experimental study to test the effects of habitat structure on scat detection dog performance. We used a domestic dog trained to detect scats from endangered spotted‐tailed quolls to undertake 120 searches across 3 habitats in both winter and summer conditions in NSW, Australia. Scat searches were located in open grassland, woodland and dense heath, and we recorded temperature, relative humidity and wind speed. Performance was measured by recording the distance at which the scat was first detected, the total search duration and the success rate of detection in each habitat.

Scat detection rates were 83% or higher in all habitats, and there was no significant difference in first detection distances between habitat structures. However, within habitats there was a significant, positive relationship between first detection distance and total search duration in the most complex habitat (P = 0·0002, R2 = 0·23, d.f. = 1, SE = 0·53).

The results support other findings showing that detection dogs can work effectively across a diversity of habitats, but specifically demonstrate that searches in complex vegetation should allow for increased search effort compared to relatively open vegetation. Otherwise, the risks of a type II error, of failing to detect a species when it is present, are likely to be higher in these habitats and this has significant implications for conservation management. The high detection rates in our results are discussed in the context of the odour thresholds used to train wildlife scat detection dogs, and we recommend future documentation of training methods to allow comparison of surveys across species and sites.

Published: April 2015

AbstractAimsTo develop a comprehensive etiological model of pathological gambling (PG) for men and women based on Kendler's development model for major depression, which groups 22 risk factors into five developmental tiers (childhood, early adolescence, late adolescence, adulthood, last year). We hypothesized that: (1) all risk factors would be associated significantly with PG; (2) the effect of risk factors in earlier developmental tiers would be accounted for by later tiers; and (3) there would be few gender differences.DesignSeparate models were built for life‐time gambling and for 12‐month PG among those with life‐time gambling.SettingData drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) in the United States.ParticipantsRespondents to NESARC wave 1 (n = 43 093).MeasurementsOdds ratios (OR) and adjusted OR (AOR) were used to determine the risk factors in multiple models.FindingsAfter mutually adjusting for other risk factors, family history of substance use disorders (SUD) or depression, impulsivity, childhood‐onset anxiety, number of Axis I and II disorders, history of SUD, nicotine dependence, social deviance in adulthood, and past‐year history of SUD, nicotine dependence and independent stressful life events predicted life‐time gambling. Past history of PG, number of personality disorders and past year nicotine dependence were associated significantly with 12‐month PG (all P < 0.05). There were no significant gender interactions for 12‐month PG.ConclusionsA modification of Kendler's model for major depression provides a foundation for the development of a comprehensive developmental model of pathological gambling. Life‐time history of gambling and 12‐month pathological gambling appear to be determined by risk factors in several developmental levels, with the effect of earlier development tiers accounted for by later ones.
Estimating the number of people with hepatitis C virus who have ever injected drugs and have yet to be diagnosed: an evidence synthesis approach for Scotland

Published: April 2015

AbstractAimsTo estimate the number of people who have ever injected drugs (defined here as PWID) living in Scotland in 2009 who have been infected with the hepatitis C virus (HCV) and to quantify and characterize the population remaining undiagnosed.MethodsInformation from routine surveillance (n = 22 616) and survey data (n = 2511) was combined using a multiparameter evidence synthesis approach to estimate the size of the PWID population, HCV antibody prevalence and the proportion of HCV antibody prevalent cases who have been diagnosed, in subgroups defined by recency of injecting (in the last year or not), age (15–34 and 35–64 years), gender and region of residence (Greater Glasgow and Clyde and the rest of Scotland).ResultsHCV antibody‐prevalence among PWID in Scotland during 2009 was estimated to be 57% [95% CI=52−61%], corresponding to 46 657 [95% credible interval (CI) = 33 812–66 803] prevalent cases. Of these, 27 434 (95% CI = 14 636–47 564) were undiagnosed, representing 59% [95% CI=43−71%] of prevalent cases. Among the undiagnosed, 83% (95% CI = 75–89%) were PWID who had not injected in the last year and 71% (95% CI = 58–85%) were aged 35–64 years.ConclusionsThe number of undiagnosed hepatitis C virus‐infected cases in Scotland appears to be particularly high among those who have injected drugs more than 1 year ago and are more than 35 years old.

Published: April 2015

SummaryMany older patients with acute myeloid leukaemia (AML) that receive standard intensive chemotherapy fail to achieve complete remission (CR). Upfront identification of patients unlikely to benefit from standard induction chemotherapy would be important for exploration of novel therapies. This study evaluated if a flow cytometric assay measuring pre‐treatment CD34+ CD38low blast frequency could predict therapeutic‐resistance in 736 AML patients entered into the UK National Cancer Research Institute AML16 trial. High peripheral blood CD34+ CD38low blast frequency (>7% of leucocytes), present in 18% of assessable patients, conferred significantly reduced CR rates (38% vs. 76%, P < 0·0001) and poor survival, and was independently prognostic for all endpoints of treatment resistance by multivariate analysis.

The purpose of this study is to compare the efficacy of a single administration of dexamethasone (DEX) on day 1 against DEX administration on days 1–3 in combination with palonosetron (PALO), a second‐generation 5‐HT3 receptor antagonist, for chemotherapy‐induced nausea and vomiting (CINV) in non‐anthracycline and cyclophosphamide (AC) moderately‐emetogenic chemotherapy (MEC). This phase III trial was conducted with a multi‐center, randomized, open‐label, non‐inferiority design. Patients who received non‐AC MEC as an initial chemotherapy were randomly assigned to either a group administered PALO (0.75 mg, i.v.) and DEX (9.9 mg, i.v.) prior to chemotherapy (study treatment group), or a group administered additional DEX (8 mg, i.v. or p.o.) on days 2–3 (control group). The primary endpoint was complete response (CR) rate. The CR rate difference was estimated by logistic regression with allocation factors as covariates. The non‐inferiority margin was set at −15% (study treatment group − control group). From April 2011 to March 2013, 305 patients who received non‐AC MEC were randomly allocated to one of two study groups. Overall, the CR rate was 66.2% in the study treatment group (N = 151) and 63.6% in the control group (N = 154). PALO plus DEX day 1 was non‐inferior to PALO plus DEX days 1–3 (difference, 2.5%; 95% confidence interval [CI]: −7.8%–12.8%; P‐value for non‐inferiority test = 0.0004). There were no differences between the two groups in terms of complete control rate (64.9 vs 61.7%) and total control rate (49.7% vs 47.4%). Anti‐emetic DEX administration on days 2–3 may be eliminated when used in combination with PALO in patients receiving non‐AC MEC.

SummaryWeight loss outcomes in overweight and obese individuals may be influenced by individual weight loss expectations (WLEs). Research on these phenomena in older women is lacking. This cross‐sectional study compared groups of younger and older women on their WLEs and related attitudes (body dissatisfaction and disordered eating). Twenty‐six younger (18–38 years) and 33 older (60–78 years) overweight and obese women were recruited from a weight loss clinic, prior to treatment. Disordered eating attitudes and body dissatisfaction were assessed using validated questionnaires and a pictorial figure‐choice scale. Participants reported 10 WLEs categorized according to personal, lifestyle and social factors. Overall, women with a higher body mass index had greater WLEs. Older women reported lower WLEs than younger women (−14.5 kg vs. −22.4 kg) in all categories except past weight. Older women perceived that career success would necessitate the greatest level of weight loss (−18.5 kg), whereas younger women derived their greatest WLEs from mass media (−28.5 kg). Both older and younger groups perceived that their families would be supportive of the smallest amount of weight loss (−8.4 and −17.6 kg, respectively). The groups did not differ on body dissatisfaction, but younger women's disordered eating attitudes were significantly higher (p < .001). Older overweight and obese women have lower WLEs than younger women but experience similar levels of body dissatisfaction and healthier eating attitudes. The attitudinal constructs underlying these differences may be useful in clinical practice to tailor age‐specific weight loss interventions.

Published: April 2015

In this study, the spinel solid solution ceramics (1−x)LiFe5O8–xLi2ZnTi3O8 (0 ≤ x ≤ 1) were prepared via the solid‐state reaction method. The phase evolution, sintering behaviors, microstructures, magneto‐dielectric properties, and microwave dielectric properties were systematically investigated. The XRD and SEM analysis indicated that the LiFe5O8 phase and the Li2ZnTi3O8 phase were almost fully soluble in each other at any proportion. Meanwhile, the evidence of ionic substitution has been directly observed at the atomic scale by means of scanning transmission electron microscopy, which is further confirmed by the Raman spectroscopy. Evidence shows that the magnetic and dielectric properties are quite sensitive to the compositions. The optimal results with remarkable magneto‐dielectric properties of μ′ = 38.2, tanδμ = 0.25, ε′ = 19.6, tanδε = 8 × 10−3 at 1 MHz, and ε′ = 19.1, Q × f = 10 400 GHz at about 7 GHz have been obtained in 0.25LiFe5O8–0.75Li2ZnTi3O8 sample. The design of complex spinel solid solution can generate novel magneto‐dielectric single‐phase ceramics combining both high permeability and good dielectric properties, which provides a way in developing multifunctional materials for applications in electronic devices.
