"It makes you think anything is possible”: Representing diversity in music theory pedagogy

This paper critiques a traditional approach to music theory pedagogy. It argues that music theory courses should draw on pedagogies that reflect the diversity and pluralism inherent in 21st century music making. It presents the findings of an action research project investigating the experiences of undergraduate students undertaking an innovative contemporary art music theory course. It describes the students’ struggle in coming to terms with a course that integrated composing, performing, listening and analysing coupled with what for many was their first exposure to the diversity of contemporary art music. The paper concludes with suggesting that the approach could be adopted more widely throughout music programs.

Corneal confocal microscopy detects neuropathy in patients with type 1 diabetes without retinopathy or microalbuminuria

Objective Corneal innervation is increasingly used as a surrogate marker of human diabetic peripheral neuropathy (DPN) however its temporal relationship with the other microvascular complications of diabetes is not fully established. In this cross-sectional, observational study we aimed to assess whether neuropathy occurred in patients with type 1 diabetes, without retinopathy or microalbuminuria. Materials and Methods All participants underwent detailed assessment of peripheral neuropathy [neuropathy disability score (NDS), vibration perception threshold (VPT), peroneal motor nerve conduction velocity (PMNCV), sural sensory nerve conduction velocity (SSNCV) and in vivo corneal confocal microscopy (IVCCM)], retinopathy (digital fundus photography) and albuminuria status [albumin: creatinine ratio (ACR)]. Results 53 patients with Type 1 diabetes with (n=37) and without retinopathy (n=16) were compared to control subjects (n=27). SSNCV, corneal nerve fibre (CNFD) and branch (CNBD) density and length (CNFL) were reduced significantly (p<0.001) in diabetic patients without retinopathy compared to control subjects. Furthermore, CNFD, CNBD and CNFL were also significantly (p<0.001) reduced in diabetic patients without microalbuminuria (n=39), compared to control subjects. Greater neuropathic severity was associated with established retinopathy and microalbuminuria. Conclusions IVCCM detects early small fibre damage in the absence of retinopathy or microalbuminuria in patients with Type 1 diabetes.

Small nerve fiber quantification in the diagnosis of diabetic sensorimotor polyneuropathy: Comparing corneal confocal microscopy with intraepidermal nerve fiber density

OBJECTIVE Quantitative assessment of small fiber damage is key to the early diagnosis and assessment of progression or regression of diabetic sensorimotor polyneuropathy (DSPN). Intraepidermal nerve fiber density (IENFD) is the current gold standard, but corneal confocal microscopy (CCM), an in vivo ophthalmic imaging modality, has the potential to be a noninvasive and objective image biomarker for identifying small fiber damage. The purpose of this study was to determine the diagnostic performance of CCM and IENFD by using the current guidelines as the reference standard. RESEARCH DESIGN AND METHODS Eighty-nine subjects (26 control subjects and 63 patients with type 1 diabetes), with and without DSPN, underwent a detailed assessment of neuropathy, including CCM and skin biopsy. RESULTS Manual and automated corneal nerve fiber density (CNFD) (P < 0.0001), branch density (CNBD) (P < 0.0001) and length (CNFL) (P < 0.0001), and IENFD (P < 0.001) were significantly reduced in patients with diabetes with DSPN compared with control subjects. The area under the receiver operating characteristic curve for identifying DSPN was 0.82 for manual CNFD, 0.80 for automated CNFD, and 0.66 for IENFD, which did not differ significantly (P = 0.14). CONCLUSIONS This study shows comparable diagnostic efficiency between CCM and IENFD, providing further support for the clinical utility of CCM as a surrogate end point for DSPN.

Small fibre neuropathy in patients with latent autoimmune diabetes in adults

The prevalence of latent autoimmune diabetes in adults (LADA) in patients diagnosed with type 2 diabetes mellitus (T2DM) ranges from 7 to 10% (1). They present at a younger age and have a lower BMI but poorer glycemic control, which may increase the risk of complications (2). However, a recent analysis of the Collaborative Atorvastatin Diabetes Study (CARDS) has demonstrated no difference in macrovascular or microvascular events between patients with LADA and T2DM, but neuropathy was not assessed (3). Previous studies quantifying neuropathy in patients with LADA are limited. In this study, we aimed to accurately quantify neuropathy in subjects with LADA compared with matched patients with T2DM.

Weed age affects chemical control of Conyza bonariensis in fallows

In the last decade, Conyza bonariensis has become a widespread and difficult-to-control weed in Australian broad-acre cropping, particularly in glyphosate-based zero-tilled fallows of the subtropical grain region. The first Australian populations of C. bonariensis, where it is known as flaxleaf fleabane, were confirmed resistant to glyphosate in 2010. Control with alternative herbicides in fallows has been inconsistent, with earlier research indicating that weed age could be a potential contributing factor. In two field experiments, the impact of weed age (one, two and three months) was measured on the efficacy of six non-selective herbicide mixtures and sequential applications for control in fallows. In another two experiments we evaluated 11 non-selective herbicides, mixtures and sequential applications applied to one and three month old weeds using higher rates on older weeds. When herbicide rates were consistent for different weed ages, efficacy was reduced only by an average of 1% when two month old weeds were treated compared to one month old weeds. However when applied to three month old weeds, efficacy of treatments was significantly (P < 0.001) reduced by 3-30%. When herbicide rates were increased, weed age had no adverse effect on efficacy, which ranged from 90 to 100%, for amitrole, glyphosate mixed with 2,4-D amine plus picloram, and three sequential application treatments of glyphosate mixtures followed with bipyridyl products. Thus, this problem weed can be controlled effectively and consistently at the rosette stage of one to two months old, or three month old weeds with several different treatments at robust rates. These effective glyphosate alternatives and sequential-application tactics will minimise replenishment of the soil seed-bank and further reduce the risk for further evolution of glyphosate resistance.

Digital access to knowledge in the preschool classroom: Reports from Australia

Australian preschool teachers’ use of Web-searching in their classroom practice was examined (N = 131). Availability of Internet-enabled digital technology and the contribution of teacher demographic characteristics, comfort with digital technologies and beliefs about their use were assessed. Internet-enabled technologies were available in 53% (n = 69) of classrooms. Within these classrooms, teacher age and beliefs predicted Web-searching practice. Although comfortable with digital access of knowledge in their everyday life, teachers reported less comfort with Web-searching in the context of their classroom practice. The findings identify the provision of Internet-enabled technologies and professional development as actions to support effective and confident inclusion of Web-searching in classrooms. Such actions are necessary to align with national policy documents that define acquisition of digital literacies as a goal and assert digital access to knowledge as an issue of equity.

Improved chemical control of Conyza bonariensis in wheat limits problems in the following fallow

Conyza bonariensis is a major weed infesting zero-tilled cropping systems in subtropical Australia, particularly in wheat and winter fallows. Uncontrolled C.bonariensis survives to become a problem weed in the following crops or fallows. As no herbicide has been registered for C.bonariensis in wheat, the effectiveness of 11 herbicides, currently registered for other broad-leaved weeds in wheat, was evaluated in two pot and two field experiments. As previous research showed that the age of C.bonariensis, and to a lesser extent, the soil moisture at spraying affected herbicide efficacy, these factors also were investigated. The efficacy of the majority of herbicide treatments was reduced when large rosettes (5-15cm diameter) were treated, compared with small rosettes (<5cm diameter). However, for the majority of herbicide treatments, the soil moisture did not affect the herbicide efficacy in the pot experiments. In the field, a delay in herbicide treatment of 2 weeks reduced the herbicide efficacy consistently across herbicide treatments, which was related to weed age but not to soil moisture differences. Across all the experiments, four herbicides controlled C.bonariensis in wheat consistently (83-100%): 2,4-D; aminopyralid + fluroxypyr; picloram + MCPA + metsulfuron; and picloram + high rates of 2,4-D. Thus, this problem weed can be effectively and consistently controlled in wheat, particularly when small rosettes are treated, and therefore C.bonariensis will have a less adverse impact on the following fallow or crop.

Parents as co-researchers at home: Using an observational method to document young children’s use of technology

This paper discusses the use of observational video recordings to document young children’s use of technology in their homes. Although observational research practices have been used for decades, often with video-based techniques, the participant group in this study (i.e., very young children) and the setting (i.e., private homes), provide a rich space for exploring the benefits and limitations of qualitative observation. The data gathered in this study point to a number of key decisions and issues that researchers must face in designing observational research, particularly where non-researchers (in this case, parents) act as surrogates for the researcher at the data collection stage. The involvement of parents and children as research videographers in the home resulted in very rich and detailed data about children’s use of technology in their daily lives. However, limitations noted in the dataset (e.g., image quality) provide important guidance for researchers developing projects using similar methods in future. The paper provides recommendations for future observational designs in similar settings and/or with similar participant groups.

“Let’s see if you can see me”: Making connections with Google Earth™ in a preschool classroom

Bringing a social interaction approach to children’s geographies to investigate how children accomplish place in everyday lives, we draw on ethnomethodological and conversation analytic approaches that recognize children’s competence to manipulate their social and digital worlds. An investigation of preschool-aged children engaged with Google Earth™ shows how they both claimed and displayed technological understandings and practices such as maneuvering the mouse and screen, and referenced place through relationships with local landmarks and familiar settings such as their school. At times, the children’s competing agendas required orientation to each other’s ideas, and shared negotiation to come to resolution. A focus on children’s use of digital technologies as they make meaning of the world around them makes possible new understandings of place within the geographies of childhood and education.

Improved management of key northern region weeds: diverse problems, diverse solutions

The cropping region of northern Australia has a diverse range of cropping systems and weed flora. A fallow phase is commonly required between crops to enable the accumulation of stored soil water in these farming systems dominated by reduced tillage. During the fallow phase, weed control is important and is heavily reliant on herbicides. The most commonly used herbicide has been glyphosate. As a result of over-reliance on glyphosate, there are now seven confirmed glyphosate-resistant weeds and several glyphosate-tolerant species common in the region. As a result, the control of summer fallow weeds is become more complex. This paper outlines project work investigating improved weed control for summer fallows in the northern cropping region. Areas of research include weed ecology, chemical and non-chemical tactics, glyphosate resistance and resistance surveys. The project also has an economic and extension component. As a result of our research we have a better understanding of the ecology of major northern weeds and spread of glyphosate resistance in the region. We have identified and defined alternative herbicide and non-chemical approaches for the effective control of summer fallow weeds and have extended our research effectively to industry.

The averaging principle and the diagram technique

Rae and Davidson have found a striking connection between the averaging method generalised by Kruskal and the diagram technique used by the Brussels school in statistical mechanics. They have considered conservative systems whose evolution is governed by the Liouville equation. In this paper we have considered a class of dissipative systems whose evolution is governed not by the Liouville equation but by the last-multiplier equation of Jacobi whose Fourier transform has been shown to be the Hopf equation. The application of the diagram technique to the interaction representation of the Jacobi equation reveals the presence of two kinds of interactions, namely the transition from one mode to another and the persistence of a mode. The first kind occurs in the treatment of conservative systems while the latter type is unique to dissipative fields and is precisely the one that determines the asymptotic Jacobi equation. The dynamical equations of motion equivalent to this limiting Jacobi equation have been shown to be the same as averaged equations.

Mies, talli ja moottoripyörä : Etnografinen tutkimus Misfit MC:stä ja bikerkulttuurin eetoksesta

Tutkimuksen punaisena lankana kulkee kysymys siitä, millainen on bikerkulttuurin eetos? Miten se on syntynyt, miten sitä ylläpidetään ja miten Misfit MC:n jäsenet sitä tulkitsevat ja toteuttavat omassa elämässään? Tarkastelen eetosta kahdenlaisen aineiston valossa. i) Kenttätyöllä (vuosina 1995-1998 ja 2000-2001) kerätyn aineiston valossa tarkastelen yhtä pääkaupunkiseudulla toimivaa HD-moottoripyöräkerhoa, vuonna 1989 toimintansa aloittanutta Misfit MC:tä. Jäsenet kutsuvat kerhoaan useimmiten talliksi, joskus pajaksi, kerhoksi tai klubiksi. Puhuessaan tallista, miehet voivat viitata kerhorakennukseen ("tuut sä tallille?") mutta myös ryhmään ("meidän talli") ja sen olemassaoloon ajallisesti ja paikallisesti. Aloittaessani kenttätyön vuonna 1995 Misfit MC:n kuului kymmenen 25-30-vuotiasta miestä. ii) Kenttätyöllä kerätyn aineiston lisäksi käytän materiaalia, joka koostuu Harley-Davidson-moottoripyörän ympärille rakentuneen bikerkulttuurin historiasta ja kulttuurituotteista, kuten kertomuksista, elokuvista, musiikista, kuvataiteesta ja moottoripyörälehdistä. Aineiston avulla valotan bikerkulttuurin eetoksen syntyä, alkuvaiheita, leviämistä ja keskeisiä elementtejä. Lähdeaineiston monimuotoisuus ja runsaus palautuu kenttätyöhöni jolloin vakuutuin siitä, että tutkimusmatka bikerkulttuurin historiaan, perinteisiin ja median välittämiin (mieli)kuviin on välttämätöntä, sillä menneisyys ja Harrikkaan ajan kuluessa varastoituneet merkitykset vaikuttavat ja ovat vahvasti läsnä Misfit MC:n toiminnassa ja talliin kuuluvien miesten elämäntyylissä. Tutkimus etenee seuraavanlaisesti. Luku I on Johdanto. Luvussa II Etnografia käsittelen etnografisen tiedon luonnetta niin tutkimusasenteena kuin kenttätyön valossa. Pohdin kenttätyötä ja sen suhdetta etnografian kirjoittamiseen eli miten kenttätyöllä kerätty aineisto muuntuu etnografiseksi monografiaksi. Käsittelen myös kenttätyöni reunaehtoja, kuten tyttöystävyyden ja sukupuolen merkitystä, ja tarkastelen tutussa kulttuurissa tehdyn kenttätyön ominaispiirteitä. Reunaehtojen kuvailu toimii myös johdatuksena bikerkulttuuriin sellaisena kuin se ilmenee Misfit MC:n tallielämässä ja käytänteissä. Lopuksi pohdin "tiheän kuvauksen" mahdollisuuksia ja vaateita aineistoni puitteissa. Luvussa III Bikerkulttuurin eetosta kartoittamassa, kuvailen Harley-Davidson-moottoripyörän ympärille rakentuneen elämäntavan syntyä, levittäytymistä ja keskeisiä elementtejä. Tarkastelen media- ja populaarikulttuurisia tekstejä (elokuvien kertomat tarinat, musiikkikappaleiden sanoitukset ja HD- ja bikerlehtien artikkelit) ja kuvia (elokuvien audiovisuaaliset aspektit, kuvataide ja HD- ja bikerlehtien kuvitus), jotka ovat vaikuttaneet bikerkulttuurin eetokseen. Luvun keskeisiä - aineistosta nousevia ja miessukupuoleen vahvasti sidoksissa olevia - käsitteitä ovat biker, outlaw ja chopper, jotka ovat bikerkulttuurissa säilyneet alkuperäisessä muodossa maantieteellisestä tai kielialueesta riippumatta. Luvussa IV Misfit MC ja bikerkulttuurin eetos temaattinen painopiste siirtyy Suomeen ja Misfit MC:hen. Aluksi käyn läpi suomalaisen bikerkulttuurin muotoutumista ja ominaispiirteitä. Alkukappaleiden jälkeen keskityn Misfit MC:n jäsenten elämäntyylin sävyihin ja heidän käsityksiinsä bikerkulttuurin eetoksesta. Analyysin kiintopisteitä ovat Misfit MC:n jäsenten näkemys bikeriydestä ja tallitoiminnasta, miesten elämäntyylin moraaliset ja esteettiset sävyt, tallirakennus miesyhteisöllisyyttä ja bikerkulttuurin eetosta luovana ja ylläpitävänä sosiaalisena tilana ja Misfit MC miesten yhteisönä. Luvussa V Eetoksen ytimessä: mies ja Harley-Davidson keskityn bikerkulttuurin ytimeen: miehen ja Harley-Davidson-moottoripyörän väliseen suhteeseen. Luvun alussa esittelen ruotsalaisen yhteiskuntatieteilijä Lars Lagergrenin moottoripyörään soveltamaa työkalu - leikkikalu - toteemi - välittäjä -typologiaa ja tarkastelen moottoripyörän olemusta sukupuolittavana ja sukupuolittuvana artefaktina. Johdanto-osion jälkeen siirryn kuvailemaan Misfit MC:n jäsenten suhdetta Harley-Davidson-moottoripyörään. Lähestyn miesten ja moottoripyörien suhdetta kahden toiminnan - moottoripyörän kunnostamisen ja rakentamisen sekä moottoripyörällä ajamisen - kautta.
