Promoting Research Writing in an Undergraduate Measurement Course

The purpose of this article is to introduce a 12-step approach for an abbreviated research project to promote research writing in an undergraduate measurement course. This 12-step approach assumes a 14-week semester schedule that is common among many colleges and universities. The steps for the proposed research project include selecting a topic, identifying and reading published research, writing the Introduction section, designing the methods, developing the Methods section, applying for Institutional Review Board approval, scheduling appointments with participants, collecting data, analyzing the data, writing the Results section, writing the Discussion section, and presenting the final product. Content of this article includes both details of the 12-step approach to research writing and a discussion of possible concerns that measurement instructors may have when considering adoption of the proposed research project.     

High-throughput particle manipulation by hydrodynamic,electrokinetic, and dielectrophoretic effects in an integrated microfluidic chip

Integrating different steps on a chip for cell manipulations and sample preparation is of foremost importance to fully take advantage of microfluidic possibilities, and therefore make tests faster, cheaper and more accurate. We demonstrated particle manipulation in an integrated microfluidic device by applying hydrodynamic, electroosmotic (EO), electrophoretic (EP), and dielectrophoretic (DEP) forces. The process involves generation of fluid flow by pressure difference, particle trapping by DEP force, and particle redirect by EO and EP forces. Both DC and AC signals were applied, taking advantages of DC EP, EO and AC DEP for on-chip particle manipulation. Since different types of particles respond differently to these signals, variations of DC and AC signals are capable to handle complex and highly variable colloidal and biological samples. The proposed technique can operate in a high-throughput manner with thirteen independent channels in radial directions for enrichment and separation in microfluidic chip. We evaluated our approach by collecting Polystyrene particles, yeast cells, and E. coli bacteria, which respond differently to electric field gradient. Live and dead yeast cells were separated successfully, validating the capability of our device to separate highly similar cells. Our results showed that this technique could achieve fast pre-concentration of colloidal particles and cells and separation of cells depending on their vitality. Hydrodynamic, DC electrophoretic and DC electroosmotic forces were used together instead of syringe pump to achieve sufficient fluid flow and particle mobility for particle trapping and sorting. By eliminating bulky mechanical pumps, this new technique has wide applications for in situ detection and analysis.     

Nothing but the Facts?

This paper seeks to understand how journalists deal with storytelling and truth-seeking in their daily news practice. While storytelling is usually studied through texts, we approached it from a practice perspective, combining data from three ethnographic studies in which 36 beat reporters and 13 journalistic storytelling experts were extensively interviewed. Because of the emphasis journalists place on “finding out the truth” in public discourses, it is tempting for academics to present them as naive truth-seekers. However, by means of an interpretative repertoire analysis of their “practice” discourses, we seek to enlarge the discursive space to talk about the supposed tension between story and reality. Although departing from the idea that all news making is storytelling, the interviewed journalists consider news making and storytelling as distinct—and sometimes opposing—practices. These professional practices serve as the framework around which five storytelling repertoires are organized.     

Haunted Trauma Narratives of Inclusion,Race, and Disability in a School Community

By typical definitions in the special education world, inclusion would not be recognizable as it exists at Memorial Elementary. Memorial is responding to a widely documented trend in public schools: over-representation of students of color, particularly Black and Brown students, in high-incidence special education categories, including emotional and behavioral disabilities (EBD). I conceptualize EBD as unacknowledged suppression of hauntings from transgenerational trauma—legacies of institutional racism, poverty, and attempts at dehumanization. My primary hypothesis is that Memorial’s practice and ethic of unconditional belonging has been a transformation afforded by being haunted. I argue that haunted trauma narratives affirm and reconstruct the personhood of students of color with ghosts of trauma. Through narrativizing, students of color and educators rebuild inclusion from difference-as-allowed toward Martin Luther King Jr.’s (2001) “beloved community” (p. 458). That is, Memorial has redesigned school structures, educators’ beliefs and practices, interactions with children and their families, and other aspects of everyday systems to be organized around the intersections of race, trauma, identity, and community. Though dreaming is undeniably difficult, Memorial also illustrates the transformative power of affective forces from ghosts that demand hope, justice, and healing.     

Das Recht auf Veröffentlichung im Spannungsverhältnis zur Drittmittelforschung

Immer öfter finden sich Wissenschaftler im Bereich der Drittmittelforschung mit der umstrittenen Rechtsmeinung ihrer Auftraggeber konfrontiert, die Verwertungsrechte an wissenschaftlichen Arbeiten stünden diesen zu. Inwieweit dies als zutreffend angesehen werden kann sowie die Beziehung zu dem im Universitätsgesetz verankerten Recht des Wissenschaftlers auf Veröffentlichung, soll den Untersuchungsgegenstand dieses Beitrages bilden.     

Who is teaching your child? The issue of unqualified subject specialists in Northern Ireland

There is a growing concern throughout the UK and beyond about the lack of suitably qualified post‐primary teachers in some subject areas, particularly mathematics, design and technology and the sciences. This paper reports on a survey of teacher qualifications in Northern Ireland which indicates that a significant percentage of teachers are unqualified in the areas of mathematics, physics, ICT, history and Irish, and that Key Stage 3 teachers tend to be less well‐qualified than those at Key Stage 4 or post‐16. Unqualified teachers are less likely to be found in the grammar sector than the non‐grammar sector.     

Integrating instruction of science,reading, and writing: Goals,teacher development,and assessment

This article describes the interplay of goals, teacher development, and assessment in the context of a yearlong research and development project. The aim of the project was to integrate the teaching of science, reading, and writing processes in a conceptually based, constructivist curriculum for middle school students who read below grade level. A performance-based assessment was designed and implemented to determine the level of student awareness and control over the processes taught during a unit of instruction. Interviews with science teachers and supervisors revealed the important interaction of curricular goals, the performance assessment, and instructional practice.     

Initiating running barefoot: Effects on muscle activation and impact accelerations in habitually rearfoot shod runners

Runners tend to shift from a rearfoot to a forefoot strike pattern when running barefoot. However, it is unclear how the first attempts at running barefoot affect habitually rearfoot shod runners. Due to the inconsistency of their recently adopted barefoot technique, a number of new barefoot-related running injuries are emerging among novice barefoot runners. The aim of this study was therefore to analyse the influence of three running conditions (natural barefoot [BF], barefoot with a forced rearfoot strike [BRS], and shod [SH]) on muscle activity and impact accelerations in habitually rearfoot shod runners. Twenty-two participants ran at 60% of their maximal aerobic speed while foot strike, tibial and head impact accelerations, and tibialis anterior (TA), peroneus longus (PL), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL) muscle activity were registered. Only 68% of the runners adopted a non-rearfoot strike pattern during BF. Running BF led to a reduction of TA activity as well as to an increase of GL and GM activity compared to BRS and SH. Furthermore, BRS increased tibial peak acceleration, tibial magnitude and tibial acceleration rate compared to SH and BF. In conclusion, 32% of our runners showed a rearfoot strike pattern at the first attempts at running barefoot, which corresponds to a running style (BRS) that led to increased muscle activation and impact accelerations and thereby to a potentially higher risk of injury compared to running shod.     

Assessing personal talent determinants in young racquet sport players: a systematic review

Since junior performances have little predictive value for future success, other solutions are sought to assess a young player’s potential. The objectives of this systematic review are (1) to provide an overview of instruments measuring personal talent determinants of young players in racquet sports, and (2) to evaluate these instruments regarding their validity for talent development. Electronic searches were conducted in PubMed, PsychINFO, Web of Knowledge, ScienceDirect and SPORTDiscus (1990 to 31 March 2014). Search terms represented tennis, table tennis, badminton and squash, the concept of talent, methods of testing and children. Thirty articles with information regarding over 100 instruments were included. Validity evaluation showed that instruments focusing on intellectual and perceptual abilities, and coordinative skills discriminate elite from non-elite players and/or are related to current performance, but their predictive validity is not confirmed. There is moderate evidence that the assessments of mental and goal management skills predict future performance. Data on instruments measuring physical characteristics prohibit a conclusion due to conflicting findings. This systematic review yielded an ambiguous end point. The lack of longitudinal studies precludes verification of the instrument’s capacity to forecast future performance. Future research should focus on instruments assessing multidimensional talent determinants and their predictive value in longitudinal designs.
