Transforming a methodological dilemma into a rewarding research opportunity
This article focuses on an investigation of English as a Foreign Language
(EFL) teacher (de)motivation in Spain which underwent a methodological
transformation from mixed methods to a qualitative approach.
Unexpected statistical results from the questionnaire in the piloting
phase led to the creation of interview prompts, a dynamic data collection
instrument based on reliable items from the questionnaire which was
disregarded from the main study at a later stage. The interview prompts
provided a card-based data collection method which engaged participants
in reflective and challenging tasks. This paper will discuss an unsettling
challenge in the research process, how it was seized and the positive
outcome which emerged from this unpredicted pitfall. A research breakdown
welcomed a methodological turn enabled by the researcher’s
reflection on the research dilemma. Authors are encouraged to defy and
embrace research obstacles while learning from them and sharing the
solutions with the research community
Magnetotransport of CeRhIn5
We report measurements of the temperature-dependent anisotropic resistivity
and in-plane magnetoresistance on single crystals of the tetragonal
heavy-fermion antiferromagnet (TN = 3.8 K) CeRhIn5. The measurements are
reported in the temperature range 1.4 K to 300 K and in magnetic fields to 18
tesla. The resistivity is moderately anisotropic, with a room-temperature
c-axis to in-plane resistivity ratio rho_c/rho_a(300 K) = 1.7. rho(T)
measurements on the non-magnetic analog LaRhIn5 indicate that the anisotropy in
the CeRhIn5 resistivity stems predominately from anisotropy in Kondo-derived
magnetic scattering. In the magnetically ordered regime an applied field H
reduces TN only slightly due to the small ordered moment (0.37mu_B) and
magnetic anisotropy. The magnetoresistance (MR) below TN is positive and varies
linearly with H. In the paramagnetic state a positive MR is present below 7.5
K, while a high-field negative contribution is evident at higher temperatures.
The positive contribution decreases in magnitude with increasing temperature.
Above 40 K the positive contribution is no longer observable, and the MR is
negative. The low-T positive MR results from interactions with the
Kondo-coherent state, while the high-T negative MR stems from single-impurity
effects. The H and T-dependent magnetotransport reflects the magnetic
anisotropy and Kondo interactions at play in CeRhIn5.Comment: submitted to Physical Review
Using clickers in a large business class: examining use behavior and satisfaction
YesAs more and more institutions are integrating new technologies (e.g., audience response systems such as clickers) into their teaching and learning systems, it is becoming increasingly necessary to have a detailed understanding of the underlying mechanisms of these advanced technologies and their outcomes on student learning perceptions. We proposed a conceptual model based on the technology acceptance model to understand students’ use behavior and satisfaction with clickers. The valid response from 138 second-year business students of Digital Marketing module taught in a British university, where clickers are extensively used in the teaching and learning process, made the basis for data analysis. The results provided a strong support for the proposed model with a reasonably adequate variance (i.e., adjusted R2) of 67% on behavioral intentions and sufficiently high variance on use behavior (i.e., 86%) and user satisfaction (i.e., 89%)
Water sensitive residential design: A vision for a browner city?
Water sensitive design has emerged on the planning and design agenda over the last few years in response to the rapid deterioration in all sectors of the hydrological cycle in and around Perth. Water balance, water quality and water consumption considerations have now become central issues in the debate over the nature and character of future growth within the Perth Metropolitan region.
This paper will briefly plot the evolution of the concept of water sensitive and the promotion of its central mission; to recapture a sense of place in the future design of the city-a place where water is scarce and a delicate natural balance characterises the relationships between soils, plants and animals.
The analysis in the paper will highlight the role of landscaping in the water sensitive design process and in particular will focus on:
-the role of vegetation as a biological filter in the process of water quality control.
-the use of tree planting and retention as a mechanism in maintaining natural water balance.
-the value of landscape enhancement as a way of selling the benefits of water sensitive design.
-the benefits of natural planting in conserving water and yet maintaining the quality and traditions of suburban lifestyles.
The paper will be extensively illustrated using local examples and will conclude on the enormous potential of landscaping to achieve the objectives of water sensitive design and, in turn, to begin to redress the sorry history of the degradation of the natural water cycle in and around Perth.
'Greening' and 'water sensitive design' can live in harmony although the forms and the shades of that green may need to be systematically reformed in the future
Understanding and Planning for Organized Community Sport in Public Parks: A Case Study of Policy and Practice in Perth
© 2017 Editorial Board, Urban Policy and ResearchEmerging shortages of community sporting facilities in Australian cities have led to calls for increased provision of playing fields through public park and open space planning processes. Drawing on a broad literature review and a specific case study of metropolitan Perth, this paper evaluates the value of organised sport as a function of contemporary public parks before proposing policy and practice to ensure that such an increase complements broader urban planning agendas. An analysis of the evolution of public park planning shows that, while the provision of organised sport was the primary function of public parks in the middle of the twentieth century, contemporary park planning is characterised by the embrace of broader ecological planning concepts such as green infrastructure and ecosystem services. These broader concepts are then applied to understand the value of organised sport held within public parks, including its unique benefits and notable limitations when considered alongside other forms of outdoor recreation. With these limitations in mind, this paper concludes by identifying existing and future policy and practice that can help to ensure that demand for community sporting facilities in new residential areas can be met in a manner that complements this ecological role for local parks
