Briefing Illustrators: Revisiting the Value of Sketch Images

In 1990 Steve Garner produced a school text book titled Design Topics: The Human Factors of Design. He briefed the various graphic artists engaged by the publishers, Oxford University Press, via nearly 140 thumbnail sketches. A comparison of these sketches with the final illustrations reveals important values of drawing. Not only do the comparisons enable the viewer to see something of the intent of the sender, they reveal processes of interpretation, selection, rejection and development, which are normally not available to examination. The paper seeks to contribute to substantiating the value of sketches to these processes of design team working. Since the author is also the originator of the sketches an additional level of insight and commentary is made available to the reader via a process of reflection.

Heraclitean Thinking: Implications for Philosophy of Education

Heraclitus was the first presocratic Ionian thinker to describe the underlying nature of reality as a set of processes in flux and to affirm the constantly changing nature of the cosmos. In this essay, I discuss four major doctrines of his thought which constitute the crux of the Heraclitean worldview. I then expound some thoughts on the relevance and implications of Heraclitean thinking for philosophy of education.     

The development of temporal metamemory

In two studies of knowledge about the properties and processes of memory for the times of past events, 178 children from 5 through 13 years of age and 40 adults answered questions about how they would remember times on different scales, how temporal memory is affected by retention interval, and the usefulness of different methods. The adults showed quite accurate knowledge about the main properties of memory for time and the processes that underlie it. Different properties and processes were first understood at ages ranging from 8 years to 12 years or later. Knowledge of the roles of reconstruction and impressions of temporal distances appear well after children use them to remember the times of events.     

On-the-Job Training: Prescriptions and Practice

This article discusses the status of workplace training in the United States, describes a model of how to conduct effective on-the-job training, and presents the results of a questionnaire based on a model designed to assess on-the-job training practices aboard Navy ships. The model views the on-the-job trainer as a coach who guides the trainee through a task using three steps: 1) assessment, 2) training, and 3) evaluation. The questionnaire was sent to over 5,000 shipboard supervisors; 2,321 responded. Results indicate that nearly 50% of the Navy supervisors who responded are not as effective as they could be. The implications of these findings for the civilian workplace are discussed.     

成功教练员应具备的10项素质

成功教练员都具备同样的素质。在20多年来的教练生涯中,笔者认为一个成功的教练员应当具备以下10项素质:一、耐心队员越年轻,教练员就越要有耐心。不要期待所有队员都能在第一时间里领会教练员所传授的技术。让队员们注意教练员传授的内容并听从指导,才是最大的挑战。对于那些不听指导的队员,必须不断提醒他们。     

Thermoneutral immersion exercise accelerates heart rate recovery: A potential novel training modality

This study compared heart rate recovery (HRR) after incremental maximal exercise performed at the same external power output (P_ext) on dry land ergocycle (DE) vs. immersible ergocycle (IE). Fifteen young healthy participants (30?±?7 years, 13 men and 2 women) performed incremental maximal exercise tests on DE and on IE. The initial P_ext on DE was 25?W and was increased by 25?W/min at a pedalling cadence between 60 and 80?rpm, while during IE immersion at chest level in thermoneutral water (30°C), the initial P_ext deployment was at a cadence of 40?rpm which was increased by 10?rpm until 70?rpm and thereafter by 5?rpm until exhaustion. Gas exchange and heart rate (HR) were measured continuously during exercise and recovery for 5?min. Maximal HR (DE: 176?±?15 vs. IE 169?±?12?bpm) reached by the subjects in the two conditions did not differ (P?>?.05). Parasympathetic reactivation parameters (ΔHR from 10 to 300?s) were compared during the DE and IE HR recovery recordings. During the IE recovery, parasympathetic reactivation in the early phase was more predominant (HRR at Δ10–Δ60?s, P?<?.05), but similar in the late phase (HRR at Δ120–Δ300?s, P?>?.05) when compared to the DE condition. In conclusion, incremental maximal IE exercise at chest level immersion in thermoneutral water accelerates the early phase parasympathetic reactivation compared to DE in healthy young participants.
