This chapter introduces the use of electronic portfolios (e-portfolios) as an assessment method in the K-12 classroom. Aligned with the constructivist approach, the term e-portfolio is considered to be an umbrella, actually comprising of various components reflecting both the teaching-learning process and the end products. Having many advantages, the use of e-portfolios is spreading all over the world. This chapter, in which issues such as conceptual underpinnings, possible advantages and challenges, implementation ideas, and content and assessment criteria for e-portfolios are also reviewed, concludes with suggestions for teachers who are interested in implementing e-portfolios into their own subject fields.

Based on the shortcomings of traditional probabilistic assessment methods, an improved probabilistic safety assessment method was proposed, which used Latin hypercube sampling, considered the change process about fatigue crack propagation, as well as the effect of random variables on the failure assessment curve. The paper also analyzed the specific example with this method. The results showed that this method was simpler and more effective, which had some value of applications in engineering.

The aim of this article is to describe the optimization of ashes processing technological line. The statistical and economic tool (risk assessment criteria) that is used in this article help to identify weaknesses in the ashes processing, managing process and potential risks and bottlenecks, thus helping to achieve better control over the process, minimizing the impact on the environment. Keywords: Ash processing, Waste storage, Risk assessment.

Purpose The purpose of this paper is to develop a Housing Eligibility Assessment Scoring Method (HEASM) for low-income Urgent Repair Programs (URPs). Design/methodology/approach In order to develop a practical HEASM that incorporates the prevailing eligibility assessment criteria for low-income URPs, a case study research approach was adopted. Emergent themes and patterns in predominant eligibility assessment criteria and methods are derived from program documents utilized by a successful State Urgent Repair Program (SURP) and its 42 Community Partners operating in the Southeastern region of the USA. Coupled with interviews and the expert analysis of SURP staff, the quantitative analysis of 11,414 repaired homes and literature reviews were used to categorize predominant eligible housing repairs and costs. Findings The five key eligibility assessment criteria categories that emerged from the data analysis are: location, owner-occupancy, family needs, housing repair, and estimated repair costs. The framework of the proposed HEASM is guided by these five categories. Originality/value URP decision makers are provided with a simple, practical, and objective eligibility assessment method that can be easily modified to accommodate the unique eligibility criteria and local program conditions. This method should improve the eligibility assessment, prioritization, and the eventual selection of qualifying applicants. Consequently, the capacity of URPs to provide funding to their targeted populations with the most critical needs would be enhanced. Insights could drive the impetus to modify existing URP.

Due to the fact that the complexity of loads and uncertainties of random variables affect the reliability of defective casings, with consideration to the disadvantages of the deterministic approach, in this paper a probabilistic assessment method is employed based on previously established safety evaluation criteria for casings with corrosion defects in thermal recovery wells. In addition, Monte Carlo simulation is proposed to analyze the casing reliability under different remaining strengths. Sensitivity analysis is then performed to rank the influence of various variables for casing failure, and finally the influence law of the main parameters on the maximum Von Mises stress of defective casing is summarized.

Abstract. Over the last two decades, several methods have been developed to reduce subjectivity of geomorphosite selection through use of transparent assessment criteria. Most of these methods propose criteria such as integrity, rarity, representativeness and palaeogeographical importance for the evaluation of the «scientific value» of sites. For the assessment of their global quality, «additional values» of ecological, cultural, aesthetic and economic nature have, at times, been taken into consideration. This paper proposes a new assessment method that integrates both sets of values into the evaluation of geomorphosites. The method is described and its implementation in two different cases presented: compilation of an inventory of geomorphosites in the National Park of Adula (Ticino, Switzerland) and evaluation of the geocultural heritage of the Trient area (Valais, Switzerland).
