First- and second-generation design and engineering students: experience,attainment and factors influencing them to attend university

Challenges for students who are ‘first-in-family’ to attend university have been discussed within widening participation discourse. However, in the UK, ‘first-in-family’ or first-generation students have frequently been conflated with those experiencing poverty or from lower socio-economic groups. This research integrated survey data with assessment data from final-year design and engineering students in a UK university to examine students’ attainment, the influences on why students decide to attend university and students’ experiences during their degree programmes. Analysis of the data showed variations in the reasons for first- and second-generation students wanting to go to university, particularly a significant difference in the influence of parents. First-generation students described significantly less parental influence on the decision to attend university than second- or subsequent-generation students. Smaller differences in students’ experiences and attainment in university were also noted. Whilst first-generation students reported differences in study habits, their attainment was, on average, marginally higher than that of their peers. Building on others’ theoretical work, which suggests the importance of social capital within higher education (HE), this research highlights the difference in social influences on both university application and expectations of university for those with and without a family history of tertiary education. Further research is needed to explore, in larger samples, whether the social influences on individuals’ perception of HE are in turn shaped by whether or not their parents attended university, and further, what impact this may have, not only on degree outcomes but also on the broader benefits typically associated with graduate experience.     

The effect of increasing written approval on Italian students’ academic performance in higher education

Increasing teacher verbal approval has been shown to produce both increased pupil “on-task” behaviour and academic achievement. The present study aimed to address gaps in current knowledge about the effect of different kinds of teacher approval, other than verbal approval, on students’ performance. An exploratory study, followed by an experimental study, was conducted with Italian undergraduate psychology students in order to investigate the effect of written approval on their academic performance. The results indicate that, whilst there is some suggestion that students appreciated receiving increased written approval comments on their work, the receipt of such comments was accompanied by poorer academic performance than that of a control group. Possible explanations are presented.     

Digital redesign of analog smith predictor for systems with long input time delays

The discretization of the analog Smith predictor by using the prediction-based state-matching digital redesign method for systems with various input time delays was recently investigated in the literature. This paper presents an alternative Chebyshev quadrature state-matching digital redesign method for discretization of the analog Smith predictor for systems with a long input time delay. In order to implement the digitally redesigned Smith predictor by utilizing the output-feedback of the plant, an ideal state reconstructor for the long input-delayed plant is established. The long dead time of interest is an integer plus a fractional input delay. An illustrative example is given to demonstrate the effective of the proposed approach.     

The improvement in walking speed induced by resistance training is associated with increased muscular strength but not skeletal muscle mass in older women

Objective: The purpose of the present study was to analyze whether improvements in fast walking speed induced by resistance training (RT) are associated with changes in body composition, muscle quality, and muscular strength in older women. Methods: Twenty-three healthy older women (69.6?±?6.4 years, 64.95?±?12.9?kg, 1.55?±?0.07?m, 27.06?±?4.6?kg/m²) performed a RT program for 8 weeks consisting of 8 exercises for the whole body, 3 sets of 10–15 repetitions maximum, 3 times a week. Anthropometric, body composition (fat-free mass [FFM], skeletal muscle mass [SMM], legs lean soft tissue [LLST], fat mass), knee extension muscular strength (KE1RM), muscle quality index (MQI [KE1RM/LLST]), and 10-meter walking test (10-MWT) were performed before and after the intervention. Results: Significant (P?<?.05) changes were observed from pre- to post-training for FFM (+1.6%), MQI (+7.2%), SMM (+2.4%), LLST (+1.8%), KE1RM (+8.6%), fat mass (?1.4%), and time to perform 10-MWT (?3.7%). The percentage change in 10-MWT was significantly associated with percentage change in MQI (r?=??0.46, P?=?.04) and KE1RM (r?=??0.45, P?=?.04), however not associated percentage of changes in SMM (r?=?0.01, P?=?.97), LLST (r?=??0.22, P?=?.33), and body fat (r?=?0.10, P?=?.66). Conclusion: We conclude that the improvement in the 10-MWT after an 8-week RT program is associated with increases in lower limb muscular strength and muscle quality, but not with muscle mass or body fat changes in older women.     

Segmental sequencing of kinetic energy in a computer-simulated golf swing

The concept of the transfer of kinetic energy (KE) sequentially through the human body from proximal to distal segments is an influential concept in biomechanics literature. The present study develops this area of research through investigation of segmental sequencing of the transfer of KE by means of computer simulation. Using a musculoskeletal computer model previously developed by the authors, driven using three-dimensional kinematic data from a single elite male golfer, combined inverse and forward dynamics analyses enabled derivation of KE. Rigid body segments of torso, hips, arms and clubhead were examined in line with previous literature. Using this method a driver swing was compared to a 7 iron swing. Findings showed a high level of correlation between driver and iron peak KE and timing of peak KE relative to impact. This seems to indicate equivalent trunk and arms linear velocity, thus force applied, for an iron shot and a driver shot. There were highly significant differences between KE output for body segments for both clubs. In addition, peak KE magnitudes increased sequentially from proximal to distal segments during swing simulations for both the driver and 7 iron. This supports the principle of the summation of speed. However, timing of peak KE was not sequential from proximal to distal segments, nor did segments peak simultaneously. Rather, arms peaked first, followed by hips, torso and club. This seems to indicate a subjective optimal coordination of sequencing.

The educational psychologist: Facing a new era

The once firm divisions between regular and special education are now fading. In many regions, the integration into regular classrooms of formerly extruded atypical students has an accepted and sometimes legally determined future. Much greater responsibility has thus fallen upon the shoulders of the classroom teacher, and when the failure of students to learn is attributed to a failure to teach them effectively, the question of professional accountability becomes poignant indeed. So, too, for the educational psychologist. Assessment, tied to placement, is no longer acceptable as a raison d'etre. His/her primary contribution in an era of integration for special education is towards improving the quality of instruction in regular classrooms and the quality of learning. Activities of educational psychologists, including assessment, research dissemination, programs of evaluation, systems analysis, and work with parents are reconstrued in this paper as contributing to better instruction in better classrooms.     

Stress and teachers of the learning disabled,behavior disordered,and educable mentally retarded

This study investigated which factors related to the professional roles of teachers of the learning disabled (LD), behavior disordered (BD), and educable mentally retarded (EMR) are most stressful, and which activities, both personal and professional, are beneficial in guarding against stress. The Special Teacher Response to Environmental Stressors (STRESS) was used to elicit responses from the 135 teachers who participated in the study. The participants rated as highly stressful legal concerns, lack of administrative and peer support, and lack of support services. In particular, teachers of the BD revealed that they were fearful of verbal and physical attacks from their students. The participants rated highly exercise and outdoor programs, confiding in significant others (i.e., wife or husband), and peer support as helpful in guarding against stress.     

Exploring effectiveness in brain removal techniques: A comparison of approaches

Brain dissection is typically an important part of teaching neuroscience in health professional programs. This results in the need to effectively remove brains, which is often performed in a gross anatomy laboratory in the same curriculum. The aim of this study was to determine the most effective method of brain removal based on the time required for removal, difficulty of removal, and preservation of key brain structures for educational purposes. Six different dissectors performed each of the three calvaria removal approaches and three different spinal cord transection methods rating them for difficulty and tracking the time required. The combination of calvaria and brainstem approaches and the order of completion was randomized to control for fatigue and previous individual experience. After all brains were removed, each was evaluated by neuroscience faculty for utility in education contexts. The study found little difference between the individual approaches for both calvaria removal and spinal cord transection in regards to quality of outcome. The use of a circumferential cut only proved to be the most time-effective method for calvaria removal while a posterior cut between C1 and C2 was the most time-effective and least difficult method for brainstem release. There was no one technique that proved to be most beneficial across all three measures. However, different approaches resulted in a different combination of benefits across the time, difficulty, and outcome ratings that should be considered in light of the individual needs of any program or researcher.     

Modes of engagement in science inquiry: A microanalysis of elementary students' orientations toward phenomena at a summer science camp

Most science educators advocate the importance of hands-on activities for learning in science. However, little research has been directed at understanding the students' orientations toward phenomena and the ways in which these orientations influence the learning experience. Through microanalyses of videotape data of a summer science camp for elementary school children, we characterize students' orientations when exploring natural phenomena as modes of engagement. The six frequently observed orientations toward phenomena include exploration mode (to find out about the object and study its basic properties), engineering mode (a focus on making something happen), pet care mode (a personal connection focused on nurturing), procedural mode (an imitation and step-following orientation), performance mode (soliciting attention using the phenomenon as a prop), and fantasy mode (an imaginative play activity which builds on some aspect of the phenomena). These modes of engagement helped provide personal contexts in which the students' interactions with phenomena took shape, and these modes were arguably as important an influence on personal contexts as other conceptual or contextual influences. © 1996 John Wiley & Sons, Inc.
