Talking about Writing – Designing and Establishing Writing Feedback and Tutorials to Promote Student Engagement and Learning

This article describes different feedback designs that have been developed at Chalmers University of Technology, Sweden. These feedback activities are part of courses and programmes that faculty at the Department of Communication and Learning in Science, Division for Language and Communication, are involved in. The feedback setup has evolved from many years of designing and delivering writing instruction within STEM education, grounded in the challenge to make feedback a meaningful learning experience for all students and improve students’ understanding of disciplinary academic writing. The feedback designs described are based on dialogue to provide feedback and as a means for students to verbalize their own understanding of text, textual features and how discipline specific content is communicated. Examples of setups are large class active feedback lectures, scaffolded peer response sessions, and guided feedback workshops. These feedback activities are explored, and we argue for how they, potentially, result in more (useful) feedback and feedforward compared to traditional written teacher-student feedback

Cycle-Slip Rate Analysis of Blind Phase Search DSP Circuit Implementations

Using FPGA-accelerated simulations, we study the cycle-slip rate of 16QAM blind phase search implementations. While block averaging suffers from degraded BER when compared to sliding-window averaging, it results in lower cycle-slip rates and power dissipation

Towards FPGA Emulation of Fiber-Optic Channels for Deep-BER Evaluation of DSP Implementations

We introduce an FPGA-based fiber-optic channel emulator, including both AWGN and carrier phase noise, which can be used to perform deep-BER simulations of DSP implementations and accurately evaluate DSP implementation penalties

Coffee, child labour, and education: Examining a triple social–ecological trade-off in an Afromontane forest landscape

In biodiversity rich agriculture–forest moasic landscapes in south-western Ethiopia, the production of coffee and food crops, including guarding them from forest-dwelling mammals, requires a high input of labour, which is supplied partly by children. Through field observations and interviews with smallholders, we studied the extent of children’s participation in coffee production and food crop guarding, its impact on school attendance and implications for sustainable development. The findings revealed that the extent of children’s participation in such work is correlated with the level of household’s income and residential location, i.e. near versus far from forests or in coffee versus non-coffee areas. Child labour and school absenteeism linked to coffee production and crop guarding are widespread problems. Some of the measures taken to mitigate the problem of school absenteeism were coercive and posed threats to poor households. The paper concludes that child work in coffee production and crop protection is at the cost of school attendance for many children, which represents a critical social justice issue and a trade-off with the economic and environmental values of the forest. Reducing poverty would likely mitigate the problem of child labour and school absenteeism and promote synergistic development in the region.publishedVersio

The Nonpenetrating Telescopic Sham Needle May Blind Patients with Different Characteristics and Experiences When Treated by Several Therapists

Background. Little is known which factors influence the blinding in acupuncture studies. Aim. To investigate if blinding varied between patients with different characteristics receiving verum or sham acupuncture. Methods. We randomised cancer patients to verum (n = 109) or sham acupuncture (n = 106) with a nonpenetrating telescopic sham needle for nausea. Level of blinding was compared between different sub-groups of patients using Bang's blinding index (BI) ranged −1 to 1 (−1 = all state the opposite treatment, 1 = all identify treatment). Results. Most patients in the verum (74 of 95; 78%, BI 0.72) and the sham (68 of 95; 72%, BI −0.60). acupuncture group believed they had received verum acupuncture. The probability for a patient to believe he/she received verum acupuncture was related to the received needling type (P = .003) and to the patient's belief in received treatment effects (P = .008). Hospital (P = .425), therapist (P = .434), previous acupuncture experience (P = .578), occurrence of nausea (P = .157), gender (P = .760), and age (P = .357) did not affect blinding. Conclusions. Blinding was successfully achieved irrespective of age, gender, acupuncture experience, treatment effect, or in which hospital or by which therapist the patient received treatment. Patients with higher belief in the effect of the treatment were more likely to believe they had received verum acupuncture
