Book reviews

Reflexivity is commonly used in qualitative research and has been posited and accepted as a method qualitative researchers can and should use to legitimize, validate, and question research practices and representations. This paper closely examines the role of reflexivity as a methodological tool as it intersects with debates and questions surrounding representation and legitimization in qualitative research, within modernist and postmodernist ideologies, and pays close attention to how reflexivity is being defined and used in present-day research. Specifically, the author identifies and discusses the problematics of four common trends in present-day uses of reflexivity: reflexivity as recognition of self, reflexivity as recognition of other, reflexivity as truth, and reflexivity as transcendence. The author argues for a move away from comfortable uses of reflexivity to what she terms uncomfortable reflexive practices and provides an overview of the work of three authors who practice reflexivities of discomfort. Practicing uncomfortable reflexivity interrupts uses of reflexivity as a methodological tool to get better data while forefronting the complexities of doing engaged qualitative research.     

Lifesource XL-18 pedometer for measuring steps under controlled and free-living conditions

The primary aim was to examine the criterion and construct validity and test–retest reliability of the Lifesource XL-18 pedometer (A&D Medical, Toronto, ON, Canada) for measuring steps under controlled and free-living activities. The influence of body mass index, waist size and walking speed on the criterion validity of XL-18 was also explored. Forty adults (35–74 years) performed a 6-min walk test in the controlled condition, and the criterion validity of XL-18 was assessed by comparing it to steps counted manually. Thirty-five adults participated in the free-living condition and the construct validity of XL-18 was assessed by comparing it to Yamax SW-200 (YAMAX Health & Sports, Inc., San Antonio, TX, USA). During the controlled condition, XL-18 did not significantly differ from criterion (P > 0.05) and no systematic error was found using Bland–Altman analysis. The accuracy of XL-18 decreased with slower walking speed (P = 0.001). During the free-living condition, Bland–Altman analysis revealed that XL-18 overestimated daily steps by 327 ± 118 than Yamax (P = 0.004). However, the absolute percent error (APE) (6.5 ± 0.58%) was still within an acceptable range. XL-18 did not differ statistically between pant pockets. XL-18 is suitable for measuring steps in controlled and free-living conditions. However, caution may be required when interpreting the steps recorded under slower speeds and free-living conditions.     

English in classrooms: only write down what you need to know: annotation for what?

The annotation of texts in the school English classroom is central to the curriculum, examination and the history of English as a school subject. In this paper we explore ‘the way it is done’ across two different classrooms. We focus on the relationship between official definitions of annotation offered by national policies and examination syllabuses and its actualization in particular classrooms. The article takes a multimodal approach: attending to all modes of representation and communication in the teaching of English including image, gesture, gaze and the spatial organization of the classroom.     

DNA capture-probe based separation of double-stranded polymerase chain reaction amplification products in poly(dimethylsiloxane) microfluidic channels

Herein, we describe the development of a novel primer system that allows for the capture of double-stranded polymerase chain reaction (PCR) amplification products onto a microfluidic channel without any preliminary purification stages. We show that specially designed PCR primers consisting of the main primer sequence and an additional “tag sequence” linked through a poly(ethylene glycol) molecule can be used to generate ds-PCR amplification products tailed with ss-oligonucleotides of two forensically relevant genes (amelogenin and human c-fms (macrophage colony-stimulating factor) proto-oncogene for the CSF-1 receptor (CSF1PO). Furthermore, with a view to enriching and eluting the ds-PCR products of amplification on a capillary electrophoretic-based microfluidic device we describe the capture of the target ds-PCR products onto poly(dimethylsiloxane) microchannels modified with ss-oligonucleotide capture probes.     

A Tale of Two Outliers: Evidence-Based Management in Non-ARL Research Libraries and Pre-NARA Presidential Libraries

Administrators in libraries of all types face the challenge of managing and planning in times of static or declining funding and rapidly changing technology. What tools do they use to gather and employ data for decision-making and evidence-based management? Are the same tools and techniques useful for all types of libraries? Although there are established measurements and metrics for academic libraries, there are few, if any, for others such as hybrid presidential libraries which are not part of the National Archives and Records Administration (NARA) system. This column identifies the metrics used by the pre-NARA presidential libraries and compares them to metrics used by a subgroup of Carnegie Research 1 and Research 2 libraries, those that do not participate in Association of Research Libraries (ARL) statistics program. It identifies similarities and differences.

Globalisation,Literacy and Society: Redesigning pedagogy and assessment

This paper draws together various strands of argument in the emerging field of 'New Literacy Studies' to put forward the view that we need to re-evaluate how literacy is conceptualised, taught and assessed. Three central themes form the basis of the argument. First, the paper points to the emergence of the so-called new economy and globalisation, and argues that the skills and knowledge base required to cope effectively with the demands of work and the demands of everyday life are increasingly changing, and differ in important ways from some of the basic skills associated with the current literacy curriculum. Second, the paper argues that society is becoming increasingly plural and diverse, and, as such, forefronts many different ways in which people make shared meaning. Yet assessment apparently requires a single standard by which meaning is validated and this, it seems, calls into question the democratic basis of learning and teaching. In the final section of the paper, we argue that we can learn from new theoretical understandings of cognition and human action in order to develop a roadmap for redesigning pedagogy and assessment.
