Abstract

In this study, a metaphor showing that climate change education operates in dynamic interaction is presented. The metaphor allows us to see the broad context and importance of the effects of climate change education. In this study, it is aimed to raise awareness about the issue by drawing attention to climate change education with a metaphor. In this direction, theory and application were made by adapting Newton's cradle to the field of climate change education. If the impacts of climate change education are conserved as a whole through understanding and development, by staying in harmony, energy is not wasted and is conserved rather than misdirected. Increasing awareness and attention to climate change education, and adopting a broad-based approach to improving the system, are thought to be more effective and beneficial in shaping the future of climate change education and therefore combating and adapting to climate change. Newton's cradle metaphor has been a helpful tool to illustrate the dynamic interaction of climate change education. Perhaps this tool can help climate warriors who want to shape and steer the future to think creatively, gain perspective and see different potential solutions.

Abstract

A pseudo steady‐state model is developed to study heat transfer, fluid flow, and the interface shape in the liquid encapsulated vertical Bridgman crystal growth. The model, which is governed by momentum, heat, and overall mass balances in the system, is solved by a finite‐volume/Newton method. Flow and temperature fields, as well as unknown melt/crystal and melt/encapsulant interfaces, are calculated simultaneously. Sample calculations are mainly conducted for the GaAs/B2O3/PBN system. Calculated results for the Germanium/graphite system are compared with finite element calculations by Adornato and Brown, and they are in good agreement. The effects of some process parameters, including the growth speed, ambient temperature profile and heat transfer conditions, on flow patterns, temperature fields and the interface shape are illustrated through calculated results. Interface inversion from concave to convex, by modifying the ambient temperature profile, is also demonstrated through computer simulation. Particularly, through an inverse problem approach, a flat interface can be easily obtained for various operation conditions.

Abstract

Purpose

The purpose of this paper is the introduction of a globally convergent algorithm into a framework for global derivative‐free optimization, such as particle swarm optimization (PSO) for which a full proof of convergence is currently missing.

Design/methodology/approach

The substitution of the classical PSO iteration by the Newton method is suggested when the global minimum is not improved. Use of surrogate models for the computation of the Hessian of the objective function is a key point for the overall computational effort. Adoption of a trust‐region approach guarantees the consistency of the present approach with the original formulation.

Findings

The approach proposed is mostly found to be an improvement of the classical PSO method. The use of surrogate models and the trust‐region approach maintains the overall computational effort at the same level as the original algorithm.

Research limitations/implications

Although the number of algebraic test functions is pretty large, a single practical example is provided. Further numerical experiments are needed in order to increase the generality of the conclusions.

Practical implications

The proposed method improves the efficiency of the standard PSO algorithm.

Originality/value

Previous literature does not provide comprehensive systematic studies for coupling PSO with local search algorithms. This paper is a contribution for closing the gap.

Abstract

While the common suggestion in leader-member exchange (LMX) research is that there is a strong relationship between LMX and performance, a closer look at these studies reveal that the performance measures in the majority of studies are primarily subjective in nature such as performance reviews. Relatively few studies examine the LMX-objective performance (OP) relationship. The findings from those studies are not consistent subjective performance studies. While most LMX studies are conducted in a work environment, this paper adds to the literature by examining this in a higher education. The findings indicated a significantly positive regression coefficient between Professional Respect and midterm grades. Based on the results, the authors introduce the idea of the “peer leader effect” and discussed the development of peer leaders.

Abstract

Faith-based nonprofit organizations often do not track the transformational outcomes of programs because these outcomes are considered intangible and difficult to quantify. Bible League International’s (BLI) Board of Directors commissioned the development of an instrument to assess the transformative impact of BLI’s programs. This was accomplished in collaboration with the Metadigm Group. From field interviews and from relevant literature, three measurement domains emerged: Program Participant Outcomes, Worker Capacity and Affiliation, and Program Function. In pilot tests, qualitative methods were used to refine the instrument. Due to time and budgetary restraints, the project ended prior to conducting reliability studies. This case study presents factors driving faithbased nonprofits to measure transformational outcomes, exposes some of the methodological challenges in accessing transformational outcomes, and provides an approach to developing an instrument to quantify transformational outcomes

Abstract

This chapter is structured for teaching young learners with other health impairments in special education. Under the Individuals with Disabilities Education Improvement Act (IDEA, 2004), other health impairments represent chronic or acute health problems such as asthma, attention deficit disorder or attention deficit hyperactivity disorder (ADHD), diabetes, epilepsy, a heart condition, hemophilia, lead poisoning, leukemia, nephritis, rheumatic fever, and sickle cell anemia and adversely affect a child’s educational performance. The chapter is organized around definitions, prevalence, etiologies, intervention strategies, and teaching considerations for selected disabling conditions in this disability category.

Abstract

Purpose

With almost half of college undergraduates engaging in friends with benefits relationships (FWBRs), the current study sought to explore the sexual decision making strategies and potential physical and psychological health outcomes behind these relationships.

Design/methodology/approach

Using self-report measures, Study 1 asked 207 undergraduates to rate the importance of motivations, maintenance rules, and future outcomes of FWBRs in their own personal experience and for other men and women. Study 2 sampled 142 undergraduate women who were asked to indicate the percentage of time they engaged in sexual behavior under the influence of alcohol or marijuana and the frequency with which they used safe sex practices in an FWBR.

Findings

Both genders appeared equally motivated to begin an FWBR; however women reported establishing permanence rules and avoiding over-attachment in the relationship as significantly more important than men. Men were more likely to prefer that the FWBR remain unchanged, however both genders agreed that a transition to a committed relationship was unlikely. Alcohol use was not significantly more prevalent in an FWBR, nor was the likelihood of practicing safe sex.

Research limitations/implications

Both studies employed the use of self-report surveys from a single university and were subject to social desirability.

Originality/value

Quantitatively examining young adults’ reasoning behind choosing to engage in FWBRs provided insight into their overarching fear of “being hurt” and their preference for “easy access” to sexual experiences. These trends may suggest a shift in dating patterns and a preference for avoiding the emotional complexities of a committed, monogamous relationship.

Abstract

Purpose

This paper aims to propose a new numerical method for the solution of the Blasius and magnetohydrodynamic (MHD) Falkner-Skan boundary-layer equations. The Blasius and MHD Falkner-Skan equations are third-order nonlinear boundary value problems on the semi-infinite domain.

Design/methodology/approach

The approach is based upon modified rational Bernoulli functions. The operational matrices of derivative and product of modified rational Bernoulli functions are presented. These matrices together with the collocation method are then utilized to reduce the solution of the Blasius and MHD Falkner-Skan boundary-layer equations to the solution of a system of algebraic equations.

Findings

The method is computationally very attractive and gives very accurate results.

Originality/value

Many problems in science and engineering are set in unbounded domains. One approach to solve these problems is based on rational functions. In this work, a new rational function is used to find solutions of the Blasius and MHD Falkner-Skan boundary-layer equations.

Abstract

The Strategic Issue Organisations — government, companies, institutions — are currently dominated by their service functions. This can be demonstrated easily by looking at the accounts of a public company. However skilfully massaged the figures are, they inevitably betray the fact that a high proportion of expenditure goes to overhead and peripherals. Administration costs, and the non‐productive elements of personnel, prestige expenses, and equipment and maintenance will be likely to effect a reduction of profit close to 30%.
