Determining the construct validity of the safety survey instrumentWindbacher, Maritza 20 February 2012 (has links)
Safety interventions must be approached in a holistic manner, by taking cognisance of the organisational system in which accidents present themselves. Thus, a need to understand the individual in context of the organisational system that he/she functions in exists. This study focuses on the relationship between attitudes, beliefs, intention, perception, control and the propensity of employees to engage in unsafe behaviour, with a view towards improving safety statistics. In this regard the study investigated the construct validity of a Safety Survey instrument, based on the responses (n=450) of employees in the mining industry. An Exploratory Factor Analysis showed that the Safety Survey instrument differentiated between two to three underlying factors. The result of the Confirmatory Factor Analysis tested two models by demonstrating the minimum requirements of the goodness of fit indexes. The construct validity of the Safety Survey instrument could be established for two nested models that identified an internal and external locus of control factor. The statistical evidence indicated an acceptable model fit. The statistical evidence validated the construct validity of the measurement model. Copyright 2008, University of Pretoria.

Assessment of Magnetic Resonance Imaging Safety: Allied Health Professional Clinical CompetenceHouser, Tiffany 01 May 2019 (has links)
Magnetic resonance imaging is a major advancement in the diagnostic imaging field. Most patients can tolerate an MRI however, there are some who are unable to complete a lengthy scan while lying completely still without sedatives or anesthesia. Non-MRI healthcare providers are trained to use equipment that is “unsafe” in the MRI suite due to the strong magnetic field. Staff who are not fully knowledgeable and trained in MRI safety measures can endanger staff and patients.
The purpose of this study was to determine the knowledge level of non-MRI healthcare providers regarding safety risks associated with MRI and to determine their level of satisfaction regarding the MRI safety training they received. This study concluded that non-MRI healthcare providers are knowledgeable about most of the safety hazards. They are satisfied with annual training but would like more in-depth material added to their current learning modules.

Normal operations safety survey : measuring system performance in air traffic controlHenry, Christopher Steven 17 April 2014 (has links)
The Normal Operations Safety Survey (NOSS) is an observational methodology to collect safety data during normal Air Traffic Control (ATC) operations. It aims to inform organizations about safety matters by using trained ATC staff to take a structured look at everyday operations. By monitoring normal operations through the use of direct over-the-shoulder observations, it is believed that safety deficiencies can be identified in a proactive manner prior to the occurrence of accidents or incidents. NOSS was developed as a collaborative effort between the International Civil Aviation Organization, ATC providers, controller representatives, government regulators, and academics to fill a gap in available ATC safety information. System designers consider three basic assumptions: the technology needed to achieve the system production goals, the training necessary for people to operate the technology, and the regulations that dictate system behavior. These assumptions represent the expected performance. When systems are deployed, however, particularly in realms as complex as ATC, they do not perform quite as designed. NOSS aims to capture the operational drift that invariably occurs upon system deployment. NOSS captures how the ATC system operates in reality, as opposed to how it was intended to operate. NOSS is premised on the Threat and Error Management (TEM) framework. TEM frames human performance in complex and dynamic settings from an operational perspective by simultaneously focusing on the environment and how operators respond to that environment. TEM posits that threats and errors are a part of everyday operations in ATC and must be managed in order to maintain safety margins. This dissertation describes NOSS and its contributions to ATC safety management systems. It addresses the validity and reliability of NOSS data and presents case studies from field trials conducted by a number of ATC providers. / text

企業風險評估與風險控制策略之研究吳及揚, Wu, Chi-Yang Unknown Date (has links)
由於現代企業面臨之風險是多變的,許多有關之法令規定已過時,企業組織可用之資源、成本和效益會產生變化,故企業要能適應未來的變局更需落實風險管理。
企業實施風險管理之重要目標,是為了在損失發生前能以節約的原則,減少憂慮,符合外界規定,並善盡社會責任;在損失發生後能生存,繼續營運,維持收益穩定,以求繼續成長等。然而企業往往會多角化擴充經營範疇,甚至在各處實施特定的經營活動,如此其風險管理將更形複雜。
本文擬以風險管理與損害防阻的實務經驗,佐以理論基礎,說明導入風險管理與損害防阻之目標、策略、程序、計畫、績效評核等,期能使各企業認識、衡量風險,藉由選擇並執行最符合經濟效益之風險管理方法,達到企業永續經營的目標。
其次,以個人在集團內執行安全管理系統和損害防阻安全查勘服務計畫的個案,說明企業損害防阻管理意義、風險的確認、分析與評估、損害防阻管理的執行與考核、績效評估等。最後再以身為企業推動風險管理與損害防阻的一份子,檢視以往歷程提出建議,期能拋磚引玉,讓更多的組織、企業和相關人士重視並推動主動式的風險控制及損害防阻管理。 / Since the risks faced by the modern enterprises are changeable, the laws and stipulations are obsolete and outdated, the resources, costs and benefits used by the enterprises organizations are subject to change, and therefore the enterprises have to carry out the risk management in order to be able to adapt the future changes in situations.
The major targets for the enterprises to implement the risk management are for the purposes of reducing the anxiety, conforming to the outside stipulations and fulfilling the social responsibilities sincerely before the losses occur; surviving, operating continually, maintaining the incomes and continuing to grow, etc. if the losses should occur. However, the enterprises often run their business diversified and even operate the specific business activities everywhere, that will make their risk management more complex.
This article intends to be written in the view of practical experiences to engage in the risk management, loss prevention and control as well as the assists of theory foundations, depicts the implementations of goals, strategies, procedures, plans and performance evaluations, etc. in risk management, loss prevention and control, anticipating various enterprises to identify and measure the risks by means of selecting and executing the risk management methods which conform to the utmost economical benefits for the goals of running businesses continually.
Next, in the case where the writer personally carried out the safety management systems and safety survey service plans of loss prevention and control in group enterprises illustrates the meaning of loss control management, the identification, analysis and evaluation of risk, and the implementation, the verification and performance evaluation of loss control management, etc. Finally, as the member of implementing enterprises risk management and loss prevention and control, the writer examines the past working processes and experiences to offer some recommendations, expecting to throw stones and bring back jade to let much more organizations, enterprises and the parties concerned think highly of and enforce the proactive risk control and loss control management.
