The aims of this study were to analyse recreational sea kayaking and touring incidents in Norway with a specific focus on wind conditions and to elaborate on practical implications for the prevention of future incidents. We included 49 incidents reported by the media between 2000 and 2014. Incidents occurred in various wind conditions, but most incidents (60%) occurred in moderate to strong breezes (9–14 m/s). Wind strength and direction were generally forecast accurately and conditions were mainly stable throughout the day of the incident. Thus, sea kayaking and touring incidents in Norway seem to happen in various wind conditions; however, paddlers should have been well informed and aware of the hazards they were facing. Future incidents could be prevented by increasing sea kayakers’ situation awareness through discussion of experts’ decision-making processes and the arrangement of situated learning experiences in realistic settings. 相似文献

ABSTRACTBy 2029, 20% of the U.S. population will be ≥65-years-old. American demographics are changing, understanding of the ≥65-year-old demographic has not. We investigated expectation variables of participants born between 1946 and 1964 in the United States, and identified how expectation trends have changed over time also describing gender differences. We used secondary data from a motivation study published in 2015 to identify the expectations of active older adults. Four years of data were used (n = 71) in a self-selection of four adventure activities (rock climbing, flat-water canoeing, white water kayaking and sea kayaking). Older adults expected experiences in the natural environment, with social factors, and where they were either starting a new activity, or honing acquired skills. They were not focused on danger or the use of personal gear. We recommend programming that caters to an aging population, as well as considerations for gender. 相似文献

Performance improvement professionals who occasionally manage projects can benefit from applying the discipline of project management. This article offers a checklist of proven techniques that lend themselves to most projects. Many techniques are applicable even in organizations lacking a project management culture. These techniques do not assume formal project management training. The checklist draws on common elements identified through a review and analysis of key sources that outline the ingredients for project success, such as communication, stakeholder engagement, executive support, and risk management. 相似文献

Adventure expeditions are characterised by their unique temporal and spatial separateness from the quotidian and their exploratory and oft times risky nature. As such they offer a multitude of possibilities in research terms for the inquisitive investigator. Few studies however have considered the researcher’s experience of exploring such settings. Primarily methodological in focus, this paper examines the challenges and management of the adventure-researcher’s multiple roles during a sea kayaking expedition. An expedition observation framework is constructed as a tool to aid the conceptualisation of the field. In a candid and reflexive social commentary, the relative and fluid positioning of the researcher in insider-outsider terms is probed and despite their nuanced differences, the interplay of ethnography and autoethnography in achieving this. The concept of existential authenticity as a complementary theoretical framework is used to illustrate the marginality and liminal nature of the adventure scape and the researcher’s task within it. 相似文献

由于信息的不完全性、抽象思维的局限性、预测的不准确性、假定的不可靠性和实施者的差异性等不确定性因素的存在 ,决策往往与风险相伴随。邓小平所说的“摸着石头过河”是一种渐进决策的方式。他提出了风险决策的各个主要环节 :制定一切政策 ,要从实际出发 ;制定一个目标十分重要 ;大胆地试 ,大胆地闯 ;每走一步都要总结经验。邓小平认为评判决策有两个标准 ,即检验认识之真理性的实践标准和以人民的利益为出发点和归宿的价值标准 相似文献

Racial disparities in teacher-issued office discipline referrals are less discussed than the well-documented suspension gaps. Discipline referrals, like suspension, can lead to lost instructional time. Although individuals are sent out of the classroom for a range of reasons, Black students, as a group, are at greater risk of being sent out than White students. In fact, studies have shown that when comparing students with similar characteristics, Black students remain at higher risk of being referred. In this article, we argue there is a need to raise teacher awareness about negative racial beliefs and the conditions under which those beliefs impact decision-making during discipline incidents. We further point out the need to foster teacher awareness about the power of positive beliefs in affecting student outcomes and the malleability of beliefs and disciplinary practices through intervention. 相似文献

在城市服务设施的建设中,部分公共设施因为具有极强的负外部效应,属于公众嫌恶厌弃型的公共设施,使公众产生了“不要建在我家后院”的抵制情结。通过分析2009年番禺垃圾焚烧事件,发现公众的心理因素、经济因素、信任危机、公平性问题以及决策的公正性是导致邻避冲突产生的原因。因此,政府需要厘清自身角色以协调多方利益,扩大公民参与以降低邻避意识,科学选址以弱化位置的邻避效应,提供风险保障以缓解居民的担忧以及合理补偿以提高满意度,借此来缓解和疏导公众的邻避情结。 相似文献

In this paper, I report the results of a 4-year study into how my students learn to become mathematics teachers during the combined 15-week methods and field placement course I teach. At the start of most weekly methods class meetings, groups of three or four students reported their critical incidents to each other, and then chose one incident to report to the whole class. Each student then submitted a written report of 10 critical incidents for grading. At the end of each semester, I administered a questionnaire about the usefulness of each of the elements of the course. Using these two main data sources, along with my own personal reflections on the course, this paper answers the question “What are the critical incidents preservice teachers encounter during their field experience, and what do they learn about teaching for understanding through reflecting on those critical incidents?” My analysis of the students’ incident reports found that the issues raised focused on four main areas: teaching and classroom management; student factors such as pre-requisite knowledge, understanding, resistance and motivation; issues concerning relationships with colleagues, students and parents; and school organizational issues such as policies and access to resources. Their learning about teaching for understanding focused on three broad areas: the conditions necessary to teach for understanding; facilitators of teaching for understanding; and barriers to teaching for understanding. The paper concludes with a discussion of the lessons learned about fostering reflection in novice teachers, and suggestions for further research. 相似文献

To identify prospectively measured risk factors of sexual assault (SA) among girls age 17 and younger. The data come from the Panel Study of Income Dynamics and are derived from interviews with 1,087 girls, their primary caregivers, and household heads. The data were collected from the girls’ first year of life through their early twenties. Factors measured during childhood were used to predict whether the girls experienced a subsequent first sexual assault before the age of 18. Prospectively measured risk factors associated with subsequent child SA included the absence of one or both parents, maternal education less than college, family income below 400% of the federal poverty threshold, low caregiver warmth, child internalizing and externalizing behaviors, impulsivity, low achievement scores, and having been classified by their school as needing special education. Girls with behavioral health problems and learning challenges are at heightened risk for sexual assault. Research on behavioral health consequences of SA should control for preexisting SA risk factors to more accurately estimate the impact of child SA on subsequent behavioral health. 相似文献

Pesticide use in and around child care centers is a potential health threat to children and staff. The implementation of integrated pest management (IPM) can reduce these risks yet child care providers receive minimal, if any, education concerning pest management. The objectives of this qualitative study are to: (a) develop a model to describe the process of implementing an IPM program in child care centers, (b) identify the facilitators and barriers to implementing an IPM program in child care centers, and (c) examine congruence between IPM practices identified on an IPM checklist with practices reported in qualitative interviews with child care managers. Interviews and IPM checklist observations were conducted with nine child care center managers in California before and after the introduction of a pilot IPM education intervention program. The qualitative analysis of the interviews revealed a four-stage IPM implementation process, from awareness of IPM, recognizing the importance of IPM and learning how to practice it, motivation and the decision to adopt IPM, to the implementation of IPM. A wide range of facilitators and barriers were identified. There was general congruence between the manager interviews and IPM checklist findings on IPM policies, practices, and management. Understanding the process of how an IPM program was implemented in these child care centers and the facilitators and barriers involved in the process can inform planning efforts for future health interventions in child care. 相似文献
