Design and environmental technologies: Does ‘green-matching’ actually help?

This paper investigates whether a green kind of design helps firms increase their capabilities for inventing in the environmental domain and whether it does so more than ‘standard’ design. It also investigates whether the effect of ‘green-matching’ between new design and technologies is conditional on firms’ innovative capabilities, as reflected by their R&D expenditure. We address these research questions with respect to the world's top R&D investors, looking at their intellectual property rights at the United States Patent and Trademark Office (USPTO) and proposing an original textual identification of green designs and trademarks. We find that green design increases environmental inventions by top R&D investors, and to a greater extent than non-environmental ones. Standard design also stimulates environmental inventions, but to a lesser extent than green design. The ‘green-matching’ actually helps, but internal innovative capabilities are required to make it effective: a green-tech ‘prize’ emerges from green design, but only once a minimum threshold of R&D expenditure has been reached.     

The cumulative and residual fatigue response associated with soccer-specific activity performed on different playing surfaces

ABSTRACT

This study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s^-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT.     

The Will,the Wit,the Judgement: The importance of an early start in productive and successful creative writing

Most traditional concepts about creative writers include the idea that creative talent is evident early - that productive and talented writers began their careers at a young age. Yet few empirical studies have actually examined this supposition. A study of 986 creative writers from the twentieth century investigated the relationship between the age at first publication and measures of productivity (numbers of works produced) and success (winning a Nobel or Pulitzer prize). While significant relationships were found between an early debut and increased productivity in poetry and total number of works, it is more noteworthy that a writer's age at first publication was not significantly related to total productivity in fiction or success. Implications for creative writers and teachers of creative writing are discussed, along with how these findings might be incorporated into the current standards-based reform efforts.     

The recursive practice of research and teaching: reframing teacher education

As a field, Teacher Education has lived with continued criticism from governmental and research bodies on the quality of professional preparation and the lack of a strong research base. We respond to such criticisms by considering possibilities for further exploration of the research of practice and the practice of research in both initial and continuing teacher education. As both a theoretical and methodological challenge, this is tied recursively with research and practice in teacher education, for teacher educators, about teacher education. We draw on the theoretical resources of practice theories, to argue that teacher education practice must be informed by the study of the practice of teaching as well as research addressing the teaching of practice. In conclusion, we make a methodological case for reframing the roles of teacher and researcher within a “thirdspace” to consider the practice of researching teaching as recursive and always regenerative.
