Abstract
Purpose
To explain the Hague Securities Convention in the context of secured financing transactions in the US and to discuss the implications of the Convention on new and existing transactions, as well as on market practice going forward.
Design/methodology/approach
This article provides a broad overview of the Hague Securities Convention and the impact of the Convention’s choice of law rules on secured financing transactions in the US involving intermediated securities, including how this deviates from previously applicable laws (such as the Uniform Commercial Code), and provides practical considerations with respect to secured financing transactions.
Findings
While in most circumstances the Convention provides for the same choice of law as previously applicable laws, there are certain scenarios where the Convention will produce a different result. Market practice with respect to perfecting security interests will likely change to take account of the Convention and to provide the parties with certainty regarding the law applicable to secured transactions.
Practical implications
The Convention calls for increased diligence with respect to the law governing the account agreement between the debtor and the securities intermediary and whether the securities intermediary has a qualifying office in that jurisdiction.
Originality/value
Practical guidance from experienced finance lawyers.

Abstract
Tier 2 intervention is defined by the application of brief, efficient, and accessible supports for students who are at risk for social-emotional and behavioral concerns. Historically, Tier 2 interventions have been delivered in accordance with a standard protocol, with each student receiving the same general strategy in an undifferentiated manner. Yet, research has suggested the potential value of an adaptive Tier 2 approach, wherein brief assessments are conducted to determine which intervention (or adapted version of one particular intervention) is best suited to a student's individual needs. Within this chapter, we provide an overview of procedures related to adaptive Tier 2 intervention and discuss different approaches one might take to this practice. We conclude with a discussion of directions for future research in this area if adaptive Tier 2 intervention is to be widely adopted, implemented, and sustained within schools.

Abstract
The contemporary focus on high fidelity implementation of research-based practices often creates tensions for educators who seek to balance fidelity with needed flexibility as they strive to improve learner outcomes. In an effort to improve how decisions are made such that flexibility is achieved while fidelity to core components is maintained, this chapter begins with a discussion of the role of fidelity in research and practice. Particular attention is given to current conceptualizations of fidelity that may help inform theoretically and empirically driven adaptations to research-based practices. Specifically, we describe adaptations based on the instructional context for implementation and the characteristics of the individual learners. A framework for adapting research-based practices is then presented with relevant examples from research designed to optimize learner responsiveness without sacrificing fidelity to core components. The chapter ends with implications and future directions for research and practice.

Abstract
Case overview
Delee founders aimed to change the way cancer radically was detected, monitored, and treated. They created CytoCatch™, a highly sensitive automated benchtop device for the rapid isolation and analysis of circulating tumor cells from blood samples to make this possible. Strategic alliances with Stanford University, Tecnologico de Monterrey, and UANL strengthened this innovative company’s purpose. Nevertheless, some questions arose when selecting a suitable business strategy to accomplish Delee’s vision. Liza Velarde, Delee’s CEO, was preparing the agenda for the company’s 2025 planning in November 2020. The journey has been challenging, and Liza Velarde faced critical decision-making milestones. What could be the most promising customer segment for her technology? What business model may work better for such a market? How can Delee reduce the time-to-market for their technology? Furthermore, how can Delee fund their development for the following years until FDA approves?
Learning objectives
With the application of this case, the teacher aspires that students understand the following crucial insights: to understand the impact of a business model strategy, identify different possible business models, and explore options; in this sense, intellectual property can offer options to the strategy; to identify and analyze the gender gap in entrepreneurship and its strategic implications; and to identify the relevance of reducing the time to market for a technological product.
Social implications
Gender inclusiveness in entrepreneurship.
Complexity academic level
Undergraduate and graduate-level.

Abstract
Social skills training (SST) is increasingly used as an adjunct to academic interventions for children and youth with learning disabilities (LD). A brief context and an overview of SST are provided and the issue related to the establishment of SST efficacy via extant meta-analyses is described. Generally, outcomes for SST efficacy are mixed, at best, with very little evidence of strong efficacy effects across the literature.

Abstract
Purpose
This study aims to discuss the effect of carbon nanotubes (CNTs) on the mechanical properties of acrylonitrile–butadiene–styrene (ABS) composites fabricated by additive manufacturing (AM). Insight into the energy-dissipation mechanisms introduced and/or enhanced by the addition of CNTs is presented in this study.
Design/methodology/approach
ABS/CNT filaments were fabricated with different concentrations of CNTs. Using a fused deposition modeling approach, unidirectional specimens were printed using a MakerBot Replicator 2X (MakerBot Industries, Brooklyn, NY, USA). Specimens were tested under static and dynamic conditions, with the loading coinciding with the printing direction, to determine elastic modulus, strength and viscoelastic properties.
Findings
A CNT reinforcing effect is evident in a 37 per cent increase in elastic modulus. Likewise, the strength of the composite increases by up to 30 per cent with an increase in weight fraction of CNTs. At low dynamic strain amplitudes (0.05 per cent), a correlation between dissipated strain energy of the butadiene phase and strength of the composite is found such that less dissipation, from constraint of the butadiene particles by the CNTs, leads to higher strength of the composite. At higher dynamic strains, the presence of a high concentration of CNT leads to increased energy dissipation, with a maximum measured value of 24 per cent higher loss factor compared to baseline specimens. Because the trend of the composite behavior is similar (with a higher absolute value) to that of neat ABS, this study’s results indicate that well-established polymer/CNT dissipation mechanisms (such as stick-slip) are not significant, but that the CNTs amplify the dissipation of the ABS matrix by formation of crazes through stress concentrations.
Originality/value
This study provides knowledge of the dissipation behavior in additively manufactured ABS/CNT composites and provides insight into the expansion to new printable materials for dynamics applications.

Abstract
Social skills deficits characterize a large proportion of students with or at risk for social, emotional, and behavioral disabilities. Social skills are viewed as academic enablers in that they are attitudes and skills that enable students to benefit from academic instruction. Alternatively, problem behaviors are viewed as academic disablers because they compete with the acquisition and performance of academic and social skills. Students lacking social skills and exhibiting competing problem behaviors are in need of systematic social skills interventions to remediate their social skills deficits. This chapter describes what is currently known about the efficacy of social skills interventions using data from both narrative reviews and meta-analyses of the social skills training literature. Based on these reviews, social skills interventions are effective with approximately 65% of students receiving these interventions. Randomized studies produce higher effect sizes, with 82% of students showing improvement compared to only 58% of students in nonrandomized studies. An example of a social skills instructional model using the Social Skills Improvement System-Intervention Guide concludes the chapter.

Abstract
Purpose
The purpose of this systematic review was to assess the determinant factors of climate change adaptation (CCA) in sub-Saharan Africa (SSA).
Design/methodology/approach
Studies that focused on determinant factors of CCA by crop–livestock farmers and pastoralists in SSA and written in English were reviewed from five major databases using the applications of Endnote and NVivo. The review process followed a sequence of steps to reach into the final selection.
Findings
A total of 3,028 papers were recovered from the databases and screened for duplicates (777) and publications before 2000 (218). The titles and abstracts of 2,033 papers were reviewed, and 1,903 of them were excluded owing to preliminary exclusion criteria. Finally, 130 papers were selected for full-text review and more detailed assessment, where 36 papers qualified for the final review. The most important determinant factors of CCA by pastoralists were household income, access to information, access to extension services, government support and access to market. In the case of agro-pastoralists, access to information, household income, age and land/livestock ownership were found as the major determinant factors. Household income, land ownership, access to information, farm size, household size and access to extension services were the determinant factors found for CCA by smallholder farmers.
Research limitations/implications
This systematic review identified the major determinant factors according to production systems and highlights the importance of considering specific factors in designing CCA strategies.
Originality/value
After clearly stating the research question, a literature search was conducted from the major databases for climate-related research, and a comprehensive search was performed by two independent researchers.

Abstract
Purpose
To investigate the mediating role of work engagement (WE) between job autonomy and cyberloafing and the moderating effect of mindfulness on the linkage between work engagement and cyberloafing.
Design/methodology/approach
This study was conducted using an online questionnaire survey. Data were gathered from 266 full-time working professionals in India. Hierarchical regression analysis and, SPSS PROCESS version 4.0 (model 14) were employed to analyze the mediated moderation effect.
Findings
Results showed that job autonomy reduced cyberloafing of employees through WE and the mediation effect was stronger when employees were high on mindfulness.
Research limitations/implications
Results indicate that job autonomy and mindfulness have a considerable impact on employee cyberloafing behavior. Organizations seeking to reduce employee cyberloafing behavior could benefit by considering job autonomy as well as supporting employee mindfulness.
Originality/value
This study adds to the understanding of cyberloafing antecedents particularly, the role of job autonomy and WE. Additionally, it examines how mindfulness self-regulates with regard to cyberloafing and contributes to the growing body of mindfulness research and its impact on counterproductive behavior at work.
