Fathers\u27 Physiological Reactions to Child-Related Stimuli and Observed Fathering Behaviors

Child abuse studies have measured physiological reactivity of parents in response to several child- and nonchild-related stimuli. Abusive parents have responded to aversive stimuli, including that which is child-related, with atypical physiological reactivity, suggesting a trait of hyperreactivity. The current study tested the hypothesis that variation in observed parenting behaviors is associated with physiological reactivity to childrelated stimuli. To explore this association, researchers measured fathers\u27 skin conductance level, heart rate and respiration rate in reaction to video segments of a quiet, crying and happy infant, then scored observed father-child interactions for the use of parenting warmth and control across four interaction tasks. Additionally, hypotheses concerning the influence of parenting stress and reported child temperament on the observed fathering behaviors were explored

An Introduction to the Higher Education in Transformation Proceedings

This paper is an introduction to the proceedings of the 2016 Higher Education in Transformation Symposium (HEIT) that was held November 2 to 4, in Oshawa, Ontario, Canada, in the Faculty of Education at the University of Ontario Institute of Technology. The overall theme for HEIT 2016 was Designing Higher Education for the Twenty-First Century. This theme addressed the many ways that colleges and universities are actively reinventing and reinvigorating higher education. The papers in this collection cover a broad spectrum of research and experiences in both Canada and Ireland. In this paper we review the main themes that arose in HEIT and we briefly discuss the establishment of the Centre for Higher Education Research, Policy and Practice (CHERPP). CHERPP will be developing higher education research networks and projects that will influence future HEIT Symposia

Stroke-related Changes in Neuromuscular Fatigue of the Hip Flexors and Functional Implications

Objective: The aim of this study was to compare stroke-related changes in hip flexor neuromuscular fatigue of the paretic leg during a sustained isometric submaximal contraction with those of the nonparetic leg and controls and to correlate fatigue with clinical measures of function. Design: Hip torques were measured during a fatiguing hip flexion contraction at 20% of the hip flexion maximal voluntary contraction in the paretic and nonparetic legs of 13 people with chronic stroke and 10 age-matched controls. In addition, the participants with stroke performed a fatiguing contraction of the paretic leg at the absolute torque equivalent to 20% maximal voluntary contraction of the nonparetic leg and were tested for self-selected walking speed (10-m Walk Test) and balance (Berg). Results: When matching the nonparetic target torque, the paretic hip flexors had a shorter time to task failure compared with the nonparetic leg and controls (P \u3c 0.05). The time to failure of the paretic leg was inversely correlated with the reduction of hip flexion maximal voluntary contraction torque. Self-selected walking speed was correlated with declines in torque and steadiness. Berg-Balance scores were inversely correlated with the force fluctuation amplitude. Conclusions: Fatigue and precision of contraction are correlated with walking function and balance after stroke

Hard Hat Ambient Liability Observer (HALO)

Capturing workplace incident information is a growing area of concern for most companies. To assist with this, the design team proposed the H.A.L.O. This design uses time-of-flight sensors connected to LEDs to create a proximity-based hazard warning system. It also records incident data using an accelerometer and micro-SD card. This helps workers avoid some of the most common workplace injuries, slips, trips, and falls and accidental collisions. Students have created a design with engineering, and marketing requirements that accomplish this task. The proposed design allows for this monitoring and mitigation systems to be attached to hard hats. Team members developed software and hardware subsystems to fit on any hardhat without hindering worker safety. The completed design uses the systems listed above register hazardous objects within 1.5m and color shifts depending on distance. Within the 150-degree FOV, any objects approaching the device are registered. In case of a possible concussive event, collision data writes to a SD card for use during an incident investigation. After a semester of development and integration, the H.A.L.O. system met the engineering requirements to assist with preventing workplace injury in a cost-effective manner

Elements of Proximal Formative Assessment in Learners’ Discourse about Energy

Proximal formative assessment, the just-in-time elicitation of students\u27 ideas that informs ongoing instruction, is usually associated with the instructor in a formal classroom setting. However, the elicitation, assessment, and subsequent instruction that characterize proximal formative assessment are also seen in discourse among peers. We present a case in which secondary teachers in a professional development course at SPU are discussing energy flow in refrigerators. In this episode, a peer is invited to share her thinking (elicitation). Her idea that refrigerators move heat from a relatively cold compartment to a hotter environment is inappropriately judged as incorrect (assessment). The instruction (peer explanation) that follows is based on the second law of thermodynamics, and acts as corrective rather than collaborative

Bullying in Scotland 2014

The primary aim of this piece of research was to obtain a picture of how children and young people are experiencing bullying in Scotland in 2014. This research was designed to: • Identify the types of bullying that is experienced by children and young people • Give a clear picture of where bullying happens and where online and offline/face to face experiences differ or coalesce • Identify from children and young people’s own experience what they feel works and what is less helpful • Identify where children and young people go online and what technology they use to get ther

Predicting, Understanding and Avoiding the Ekofisk Rotor Instability Forty Years Later

LectureThis famous machine is re-examined to assess how well (or not) current design and analytical methods have evolved to avoid shaft whip instability. In addition to reviewing the compressors history and design evolution, the rotordynamic performance of a newly configured machine, based on todays technology, is compared against the original design

Stroke-related Effects on Maximal Dynamic Hip Flexor Fatigability and Functional Implications

Introduction: Stroke-related changes in maximal dynamic hip flexor muscle fatigability may be more relevant functionally than isometric hip flexor fatigability. Methods: Ten chronic stroke survivors performed 5 sets of 30 hip flexion maximal dynamic voluntary contractions (MDVC). A maximal isometric voluntary contraction (MIVC) was performed before and after completion of the dynamic contractions. Both the paretic and nonparetic legs were tested. Results: Reduction in hip flexion MDVC torque in the paretic leg (44.7%) was larger than the nonparetic leg (31.7%). The paretic leg had a larger reduction in rectus femoris EMG (28.9%) between the first and last set of MDVCs than the nonparetic leg (7.4%). Reduction in paretic leg MDVC torque was correlated with self-selected walking speed (r2 = 0.43), while reduction in MIVC torque was not (r2 = 0.11). Conclusions: Reductions in maximal dynamic torque of paretic hip flexors may be a better predictor of walking function than reductions in maximal isometric contractions

Developing a growth-transition matrix for the stock assessment of the green sea urchin (Strongylocentrotus droebachiensis) off Maine

The green sea urchin (Strongylocentrotus droebachiensis) is important to the economy of Maine. It is the state’s fourth largest fishery by value. The fishery has experienced a continuous decline in landings since 1992 because of decreasing stock abundance. Because determining the age of sea urchins is often difficult, a formal stock assessment demands the development of a size-structured population dynamic model. One of the most important components in a size-structured model is a growth-transition matrix. We developed an approach for estimating the growth-transition matrix using von Bertalanffy growth parameters estimated in previous studies of the green sea urchin off Maine. This approach explicitly considers size-specific variations associated with yearly growth increments for these urchins. The proposed growth-transition matrix can be updated readily with new information on growth, which is important because changes in stock abundance and the ecosystem will likely result in changes in sea urchin key life history parameters including growth. This growth-transition matrix can be readily incorporated into the size-structured stock assessment model that has been developed for assessing the green sea urchin stock off Maine
