Worldwide, schools implement social-emotional learning programs to enhance students' social-emotional skills. Although parents play an essential role in teaching these skills, knowledge about their perspectives on social-emotional learning is limited. In providing insight into the perspectives of parents from adolescent students this paper adds to this knowledge.

An explorative qualitative study was conducted to gain insight into parents' perspectives (N = 32) on adolescent social-emotional learning. A broadly used professional framework for social emotional learning was used as a frame of reference in interviews with parents from diverse backgrounds. Within and across case analyses were applied to analyze the interviews.

A conceptual model of four social-emotional skills constructs considered crucial learning by parents emerged from the data: respectful behavior, cooperation, self-knowledge and self-reliance. Parents' language, interpretations and orderings of skills indicate that the model underlying these constructs differs from skills embedded in the professional framework.

Participants were small in number and mainly female. Therefore, more research is necessary to test the model in other parent populations.

The social-emotional skills students in prevocational secondary education learn at home differ from those targeted in SEL programs. Engaging students’ parents in SEL program implementation is indicated to align the skills taught at home and school. Preparing teachers to implement such programs requires training them on engaging parents from diverse backgrounds.

The study is one of the first providing insight into parents’ perspectives on SEL, the social-emotional skills deemed crucial to master for adolescents, and the roles they view for themselves and school on teaching these skills.

Rich Internet Application (RIA) technologies offer designers the opportunity to experiment with novel interaction grammars, whose implications for conceptual modeling still need to be fully understood. An open problem is the ability to characterize the fluid, smooth and organic nature of the user interaction and navigation in ways that allow web engineers to share through a common vocabulary, as well as sketch, explore and specify design decisions in the light of usability requirements and stakeholder's goals. The purpose of this paper is to address this problem.

To meet this challenge, the authors extend IDM (Interactive Dialogue Model), a dialogue‐based approach focusing on the conceptual dialogue flow with the user, codifying a set of key modeling constructs in order to describe the new dialogue features of RIAs.

The approach, called Rich‐IDM demonstrated some relevant features: expressiveness to capture interactive features at a high level of abstraction, semi‐formality to facilitate the establishment of a common ground between designers and web engineers, and traceability of the design to important usability requirements.

The paper proposes a simple way to fill the gap between hypermedia design and user experience design for RIAs, which is an open issue, both from the web engineering point of view and the human‐computer interaction point of view.

The authors have described how Rich‐IDM can help designers to capture and cope with some RIA interface flaws. In this case, the benefits of the approach are directly related to the semantics of its primitives.

The authors' proposal is the first, consolidated step of a promising research avenue.

The purpose of this paper is to provide a detailed review of radiation dosimetry techniques based on optical fibre dosimeters. It presents a comprehensive bibliography of the current research activities in the area.

A range of published work on optical fibre radiation dosimeters are presented, with the merits and limitations discussed. Each radiation dosimetry technique is discussed in turn, providing examples of dosimeters using such techniques reviewed. The main focus is on gamma radiation although other radiation dosimeters are considered.

This paper provides information on the wide range of research activity into radiation dosimeters. The dose ranges of these dosimeters are presented, along with the advantages and disadvantages of different dosimetry techniques.

A comprehensive review of published research in the area of solid radiation dosimetry is presented in this paper. It provides an individual with a review of the various techniques used and most recent research in that field.

The purpose of this paper is to identify possible reasons for insurance companies' scant interest in real estate as investment asset in Poland. The authors attempt to determine the impact of real estate investment on insurance companies' profitability.

After collecting the aggregated data about insurance companies' financial results for the period 2000‐2008 the authors analyzed the relationship between real estate investment and profitability indicators such as return on assets (ROA), return on equity (ROE) and return on sales (ROS). This approach reflected the shareholders' point‐of‐view. Subsequently, the same kind of analysis was carried out to investigate the impact of real estate investments on the insurance companies' return on technical activity (RTA) and return on investment activity (RIA). These indicators are meant to assess business performance from the point‐of‐view of insured persons.

The analysis revealed some negative correlations: real estate investments may reduce the profitability of insurance companies. If this is true, the unwillingness of insurance companies to purchase property would not be surprising. Yet, this conclusion should be accepted with caution.

Due to the short study period and changes in legal classification of investment categories, the available data were very imperfect and the study results may not be perceived as undisputable, hence, it is felt that further research is needed.

The paper is original, as previously no such research has been conducted in Poland.

Discusses how resources are allocated in capitalist and socialist economies comparing the concept of interest (e.g. for present value calculations) with the use of capital charges (e.g. for calculating opportunity cost). Contrasts the Islamic economic system, which rejects interest but considers moral factors and the will of Allah when measuring welfare. Explains how these ideas can be expressed in the accounting price of capital (for objective factors) and by Islamic welfare criteria; and how they differ from the Pareto Criterion and capitalist concepts of utility. Lists four principles and 12 welfare criteria for an Islamic allocation of resources; and some hints on their practical application before summarizing the conclusions.

The following is an overview of how the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), applies to securities professionals such as registered investment advisers (“RIAs”) and registered broker‐dealers who advise, manage, or trade for investment portfolios of employee benefit plans subject to ERISA. The principal focus of this outline is on securities registered under the Securities Act of 1933 (the “1933 Act”) and the Securities Exchange Act of 1934 (the “1934 Act”), and securities of investment companies registered under the Investment Company Act of 1940. Many of these principles also will apply directly to unregistered securities, as well as to other investments offered by banks, insurance companies, commodity trading advisers and real estate advisers, though there may be some variation.

Previous studies on housing affordability in China were concentrated in China’s coastal and central regions. The purpose of this paper is to investigate housing affordability of urban residents in Northwest China. Moreover, this paper attempts to understand the consistency and influencing factors of various indicators on the evaluation of housing affordability.

This paper uses multiyear data on house sales, residents’ incomes and living expenses from 2011 to 2022. House price-to-income ratio, housing affordability index and residual income approach were calculated by using these data and used as the measure of housing affordability.

The results show that there are obvious differences in the housing affordability among the Xi’an, Lanzhou and Yinchuan during 2011–2022, and the housing affordability of residents in cities with small population and economic scale is better. The ability of most urban residents to afford suitable housing is still poor, and the ability to afford small-sized housing is better. Most families with below-middle income have poor housing affordability. It is also observed that although various indicators had similarities in the evaluation of residents’ housing affordability, the comprehensive evaluation results of multiple indicators were more reliable.

The research results provide a basis for the decision-making of the government’s urban housing policy and improvement of residents’ housing conditions.

The results have a clear understanding of the housing affordability of urban residents in Northwest China. The study found that the geographical location and topography of the city is also a factor affecting the housing affordability.

The purpose of this paper is to provide an overview of how the Employee Retirement Income Security Act (“ERISA”) of 1974, as amended , applies to securities professionals such as registered investment advisers, registered broker‐dealers and individual registered representatives and financial planners who advise, manage, or trade for investment portfolios of private employee benefit plans and individual retirement accounts.

The paper is designed as a primer to familiarize securities professionals with the terminology, scope and subject‐matter of ERISA as it applies to benefit plan investment transactions. When appropriate, the regulatory framework of ERISA is compared and contrasted with the more familiar securities law regulatory scheme.

The various Federal laws loosely known as “ERISA” significantly impact securities professionals in connection with the marketing of financial products and services to employee benefit plans, including IRAs, and it is critical that securities professionals have a general overview of how they do so.

The research set out is only a broad summary, and covers an area of law that is rapidly developing. It should not be considered a definitive summary of the law but a starting‐point for further, in‐depth inquiry.

Any financial professional seeking to develop or market financial products and services to benefit plans can use the paper to become familiar with the framework and terminology of ERISA.

This is a reprint of a paper first published in 2004, with extensive revisions to reflect sweeping changes in the law and new developments in the financial marketplace, plus an overview of “hot topics”.

Procurement is an increasingly important activity within most firms, and severe financial and operational consequences can result from the failure to optimize the procurement function. The multiple criteria, including the financial significance, involved in the selection of a sole‐source vendor are addressed here. Two multicriteria approaches to decision support for vendor selection are presented and are demonstrated through an example. One approach, the simple multiattribute rating technique, is relatively widely used in selection problems. The other approach, data envelopment analysis, is rarely used in such problems but serves as a very acceptable alternative for supporting the vendor selection decision. The results from these two approaches are compared to those based upon a pure aggregation and averaging procedure. For the example being considered, both multicriteria approaches provide similar results, which differ considerably from those for pure aggregation. In addition, the short‐term financial implications are examined so as to underscore the commitment needed by management if non‐cost criteria are to be incorporated into vendor selection.
