Abstract
Cyclic voltammetric measurements were recorded on various synthetic electroless copper plating baths. The shapes of the current potential curves were observed as various components of the bath were added to an alkaline Cu‐EDTA solution. Peak potentials, Ep, were measured to identify the various species undergoing oxidation or reduction.

Abstract
The Least Restrictive Environment (LRE) requirements of the Individuals with Disabilities Education Act address factors to consider in educating students with and without disabilities together to the maximum extent appropriate. This chapter is designed to examine the origins and evolving interpretations of the LRE concept in special education policy and practice. Discussion traces the evolution of the concept as a legal principle, and reviews its application to educational strategies for students with learning and behavioral disabilities in contemporary schools. In conclusion, the future of the LRE concept is addressed in light of competing policies promoting presumptive inclusive education, and publicly funded school choice programs promoting greater involvement of parents in choosing where their children with and without disabilities should be educated.

Preparation of chelating resin to be used in the removal of heavy metal ions from solutions.
Abstract
Purpose
Preparation of chelating resin to be used in the removal of heavy metal ions from solutions.
Design/methodology/approach
Chelating resin based on poly (glycidyl‐methacrylate‐co‐N, N‐methylene‐bis‐acrylamide) containing ethylenediamine was synthesised and used in removal of heavy metals from solutions.
Findings
The optimal pH values for adsorption of different metal ions occur in the range 4.0‐10.0 depending on the metal ion used. The adsorption of metal ions increases with increasing treatment duration to reach to the equilibrium state. Also, the adsorption of metal ions depends on the degree of cross linking of the chelating resin, and a higher degree of cross linking results in a lower degree of metal ion adsorption. The chelating resin was highly effective for the collection of metal ions by batch and column methods. The metal ions adsorbed could be eluted with 2M HNO3 except Co2+ and the resin could be reused.
Research limitations/implications
The different factors affecting the metal ions (Cu2+, Co2+, Cd2+, Zn2+, Pb2+ and Hg2+) loading in resin such as pH, contact time and cross linking density were studied.
Practical implications
The practical applicability of the chelating resin for final stage of waste water treatment is recommended for use as a polishing agent.
Originality/value
The resins prepared were used successfully in removing heavy metals from water.

Abstract
Purpose
Mood and anxiety disorders affect 20–30 percent of school-age children, contributing to academic failure, substance abuse, and adult psychopathology, with immense social and economic impact. These disorders are treatable, but only a fraction of students in need have access to evidence-based treatment practices (EBPs). Access could be substantially increased if school professionals were trained to identify students at risk and deliver EBPs in the context of school-based support services. However, current training for school professionals is largely ineffective because it lacks follow-up supported practice, an essential element for producing lasting behavioral change. The paper aims to discuss these issues.
Design/methodology/approach
In this pilot feasibility study, the authors explored whether a coaching-based implementation strategy could be used to integrate common elements of evidence-based cognitive behavioral therapy (CBT) into schools. The strategy incorporated didactic training in CBT for school professionals followed by coaching from an expert during co-facilitation of CBT groups offered to students.
Findings
In total, 17 school professionals in nine high schools with significant cultural and socioe-conomic diversity participated, serving 105 students. School professionals were assessed for changes in confidence in CBT delivery, frequency of generalized use of CBT skills and attitudes about the utility of CBT for the school setting. Students were assessed for symptom improvement. The school professionals showed increased confidence in, utilization of, and attitudes toward CBT. Student participants showed significant reductions in depression and anxiety symptoms pre- to post-group.
Originality/value
These findings support the feasibility and potential impact of a coaching-based implementation strategy for school settings, as well as student symptom improvement associated with receipt of school-delivered CBT.

Abstract
Purpose
The purpose of this paper is to systematically review and analyze the academic literature on integrating equity, diversity, and inclusion (EDI) into knowledge mobilization (KMb).
Design/methodology/approach
This systematic literature review of the body of scholarly literature published on integrating EDI with KMb follows established methods and protocols proposed by Popay et al. (2006) and Page et al. (2021). Using a relevant keyword string, a search was conducted in ProQuest and SCOPUS to find peer-reviewed articles, which were then screened using predetermined inclusion and exclusion criteria. Finally, inductive and deductive analyses were conducted on the selected articles.
Findings
The findings suggest that most of the authors are based in the Global North, the majority of literature was published in the last two years, and that it is conceptual. This synthesis highlights five solution-oriented themes: acknowledging inherent bias, centering marginalized groups, promoting responsible knowledge mobilization, establishing partnerships, and advocating for transformational and systemic change. This study also identifies four broad barriers: inherent, unconscious, and implicit biases, a lack of evidence-based best practices, siloing of research and information, and a lack of institutional support and resources. Findings also highlight the value of further research into barriers, gaps and opportunities.
Originality/value
By studying the intersection of EDI and KMb, this contemporary synthesis of the state of the field presents opportunities for future research into gaps, barriers and potential solutions.

Abstract
Purpose
This chapter focuses on how the repression of political ideologies can silence feminist voices. It examines how writings by women working with the U.S. Communist Party in the 1930s, 1940s, 1950s, and early 1960s have been overlooked even though they presaged important linchpins of U.S. second-wave feminist thought.
Methodology/approach
This study is based on historical and archival research.
Findings
Decades before the rise of second-wave feminism, women in the CPUSA had: (1) produced a political economy of domestic labor; (2) employed an intersectional analysis of the interlocking oppressions of race, gender, class, and nation; and (3) called for a global feminist analysis that linked these multiple oppressions to colonialism and imperialism.
Social implications
This study illustrates the costs of political repression and how the canon of feminist thought can be enhanced by resuscitating subjugated knowledges.
Originality/value
Too little attention has focused on the silencing of women because of their political ideologies. This chapter addresses this lacuna in feminist studies and calls into question the oft-repeated notion that the periods between the waves of U.S. feminism were times of movement stagnation. It shows how theory construction can flourish even when feminist activism wanes.

Abstract
Purpose
The purpose of this paper is to present a sliding mode attitude controller for reusable launch vehicle (RLV) which is nonlinear, coupling, and includes uncertain parameters and external disturbances.
Design/methodology/approach
A smooth second-order nonsingular terminal sliding mode (NTSM) controller is proposed for RLV in reentry phase. First, a NTSM manifold is proposed for finite-time convergence. Then a smooth second sliding mode controller is designed to establish the sliding mode. An observer is utilized to estimate the lumped disturbance and the estimation result is used for feedforward compensation in the controller.
Findings
It is mathematically proved that the proposed sliding mode technique makes the attitude tracking errors converge to zero in finite time and the convergence time is estimated. Simulations are made for RLV through the assumption that aerodynamic parameters and atmospheric density are perturbed. Simulation results demonstrate that the proposed control strategy is effective, leading to promising performance and robustness.
Originality/value
By the proposed controller, the second-order sliding mode is established. The attitude tracking error converges to zero in a finite time. Meanwhile, the chattering is alleviated and a smooth control input is obtained.

Abstract
Purpose
The purpose of this study is to examine the factors that affect managers’ ethical decision-making in export-oriented readymade garments in Bangladesh.
Design/methodology/approach
This is an empirical study based on the quantitative approach undertaking a cross-sectional survey method where a convenience sampling technique was applied. The analysis was done using partial least square structural equation model applying Smart-PLS version 3.0.
Findings
This study confirmed that all the components of cognitive appraisal processes, including perceived severity, perceived vulnerability, response efficacy and self-efficacy, have a significant influence on attitude. Attitude, in turn, mediates the relationship between these variables and the behavioural intention of ethical practice, except for perceived vulnerability. Besides, moral obligation is found to mediate the relationship between attitude, self-efficacy and the behavioural intention of ethical decision-making. The study also found that ethical climate and subjective norms have a direct influence on behavioural intention. Furthermore, behavioural intention, ethical climate and self-efficacy are positively related to actual decision-making behaviour. However, this study did not find any direct effect of subjective norms on moral obligation.
Practical implications
The organization should include an emphasis on building ethical culture and setting an ethical code of conduct within the organization to sustain ethical practice within employees. However, the practitioner should work on enhancing self-efficacy to curb unethical practices by individuals.
Originality/value
This research contributes to the management of garments manufacturers by a practical and theoretical understanding of what influences the ethical behavioural decision-making process. Valuable guidelines are provided on the ethical decision-making process in the garments manufacturing companies for future researchers.

Abstract
We consider the theory and evidence supporting learning styles, and contrast these with the related concepts of learning preferences and student choice. Although the theory of learning styles remains popular in the field of education as one guidepost teachers might use to maximize the effectiveness of instruction for individual students, including students with learning and behavioral disabilities, a review of the evidence supporting a learning styles approach suggests that it offers little benefit to students with disabilities. In contrasting learning styles with the related concept of learning preferences, we posit that interventions based on student choice may offer a more parsimonious and evidence-driven approach to enhancing instruction and improving outcomes for students with learning and behavioral disabilities.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Abstract
Purpose
This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.
Design/methodology/approach
This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.
Findings
This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.
Originality/value
This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.
