In order to find a more appropriate way of evaluating mining titles, the Black-Scholes model is discussed in this paper. The authors pay particular attention to the determination of the time to maturity of the option on the basis of characteristics of the mining industry, pointing out that a reasonable time to maturity of the option should be the remaining time after deducting the essential time, needed by exploitation of the mineral resources within the mining property, from the life of the mining title. Several conclusions, related to the exercise of mineral resource management, are drawn from a case study analysis; extending the life of a mining title within a certain range could increase the revenue to the seller of the mining title. Application of the Black-Scholes model to evaluate mining titles would encourage an expansion of the scale of production.展开更多

However, the lack of a widely accepted instrument to assess the impact of CPD activities on clinical practice thwarts researchers’ assessment of the effectiveness of CPD activities. The objective of the study is to develop a theory and practice-based, valid, reliable national instrument to assess the impact of accredited CPD activities on reducing maternal and neonatal mortality in Kenya using an integrated model for the study of healthcare professionals’ behavior through environmental scanning of the factors that promote good performance. The researcher will analyze the instruments identified in a systematic review of factors motivating and demotivating nurses and midwives’ behaviours using criteria that reflect the literature on measurement development of CPD leaders and providers’ priorities. The outcome of this phase will be an inventory of instruments using a competence-based model. Working from this inventory, the most relevant items for assessing the concepts listed will be selected. Then, the researcher will verify whether these items are acceptable or need modification, what aspects need revision, and whether important items are missing and should be added. The outcome of this phase will be a new national instrument integrating the most relevant tools to fit our integrated model of healthcare professionals’ behavior. Two data collections are planned: 1) pretesting of the new instrument, to assess its reliability and validity and 2) a study using the instrument before and after CPD activities with randomly selected groups, one acting as control group to assess measurement effect. The researcher will conduct individual interviews and focus groups with CPD providers and leaders to identify anticipated barriers and enablers for implementing the new instrument in CPD practice. Drawing on the results from the previous phases, we will use consensus-building methods with the decision makers to develop a plan to implement the new instrument.展开更多

In terms of knowledge features of power system operation mode, we studied a training method based on evaluation of learning state. This training method makes individual learning for different individual condition to give them ability to grasp learning points quickly, evaluate real-time learning effect, update learning style in time and summarize problems after one learning stage, so that learners can master professional knowledge in constant summaries and feedbacks. Obvious effects can be obtained on discontinuous learning time that trainees can master basic theories associated with their working and operations adapted to practical work quickly.展开更多

Designing and implementing an effective radiologic technology educational program curriculum requires a disciplined pedagogical approach where the instructor performs a thorough situational analysis, develops a theory based and pragmatic learning plan, and implements a course of study in accordance with the established educational guidelines and requirements. Diligent efforts are needed to enhance the relationship amongst curriculum developers and evaluators. The collection of information at the formative stage: followed by process evaluation to assess implementation as the curriculum progresses, and summative evaluation to assess impact is required for accreditation of program in the United States by the Joint Review Committee for Education in Radiologic Technology. Formative evaluation research is used to enhance effectiveness of the curriculum, guide development of teaching and learning strategies, and reveal promising and ineffective components of curriculum. This review of literature provides evidence as to what is considered to be the best practice in the program evaluation/accreditation process.展开更多
