Abstract
Alternative education settings (AES; i.e., self-contained alternative schools, therapeutic day treatment and residential schools, and juvenile corrections schools) serve youth with complicated and often serious academic and behavioral needs. The use of evidence-based practices (EBPs) and practices with Best Available Evidence are necessary to increase the likelihood of long-term success for these youth. In this chapter, we define three primary categories of AES and review what we know about the characteristics of youth in these schools. Next, we discuss the current emphasis on identifying and implementing EBPs with regard to both academic interventions (i.e., reading and mathematics) and interventions addressing student behavior. In particular, we consider implementation in AES, where there are often high percentages of youth requiring special education services and who have a significant need for EBPs to succeed academically, behaviorally, and in their transition to adulthood. We focus our discussion on: (a) examining approaches to identifying EBPs; (b) providing a brief review of EBPs and Best Available Evidence in the areas of mathematics, reading, and interventions addressing student behavior for youth in AES; (c) delineating key implementation challenges in AES; and (d) providing recommendations for how to facilitate the use of EBPs in AES.

Abstract
Purpose
Knowledge-intensive entrepreneurial firms succeed when they can better marshal their knowledge resources into productive advantages, necessitating entrepreneurial orientation (EO) and knowledge management (KM) processes of knowledge acquisition, application, conversion and protection. However, configurations of EO and KM processes are unaccounted for in extant theory, and the differences between the operating context of knowledge-intensive entrepreneurial firms are unclear. Therefore, this study investigates the configurational combination of EO and KM processes in two different contexts as native and immigrant entrepreneurial firms.
Design/methodology/approach
Drawing on the knowledge-based theory, the authors apply fuzzy-set qualitative comparative analysis (QCA) and necessity analysis of QCA (NCA) to data from Malaysian native (N = 185) and immigrant (N = 146) service-oriented entrepreneurial firms.
Findings
The results demonstrate that immigrant entrepreneurial firms’ performance relies on knowledge processes of knowledge acquisition and application to ensure intelligent effectuation of EO; but for native entrepreneurial firms, the critical knowledge processes for performance success are knowledge conversion and protection. The NCA suggests that EO is critical for both firms; however, conjunctional causations differ based on KM processes.
Originality/value
This study enriches the emerging knowledge-based theory of the entrepreneurial-oriented firm by advancing the theory and conversation by revealing how EO, KM processes and context link in which the profile of the EO–performance relationship is configurationally dependent. The study advances the knowledge-based theory of entrepreneurially-oriented firms to account for entrepreneurship in context.

Abstract
While deficits for students with learning disabilities (LD) are prevalent in almost all aspects of mathematics, difficulty in the application and understanding of problem-solving tasks are much more challenging to remediate than computational and procedural skills. Given the complexities involved in authentic problem-solving activities emphasized in current mathematics standards and the inherent challenges presented to students with LD, the importance of using strategies and techniques guided by evidence-based practices is paramount. Yet, ineffective instructional strategies for problem solving are still widespread in both mathematics curricula and available teacher resources. In this chapter, we provide a description of a commonly used ineffective problem-solving strategy (i.e., the keyword strategy), an overview of the keyword research, and an explanation for its ineffectiveness. We conclude with a description of three evidenced-based problem-solving approaches and practices that significantly improve the mathematical performance of students with LD.

Abstract
Purpose
This article investigates (in)direct relationships between team-level entrepreneurial orientation and team performance, where team entrepreneurial orientation (EO) is measured as a team-level construct, not as concentration of team members' scores. In this article, the authors present and explore how EO-oriented behaviour within a team affect its performance, taking into account the team's trust in a manager and commitment to team and company goals.
Design/methodology/approach
This article focuses on a quantitative analysis of 55 teams operating within a large high-tech manufacturing enterprise, gathered through a traditional survey. The conceptual framework for this research was based on the theories of organisational citizenship, extra-role behaviour and social exchange. The authors explain how contextual factors establish a framework which enables team EO transformation towards higher performance of teams.
Findings
The results show that (team) performance benefits from EO-related behaviours. However, individual dimensions of EO are not universally beneficial and need to be combined with a mutual trust and/or commitment to team enterprise's goals to achieve high performance.
Originality/value
The findings provide important insight into which team factors may be targeted at the intervention or support of team members, including managers and immediate superiors who lack an active personality and are not willing to take risks at workplace. The authors adopted EO instruments, mutual trust and commitment from an individual scale to a team one, and also offer new opportunities to analyse such phenomena from a new level and evaluate them from the perspective of team managers.

Abstract
The traffic assignment problem aims to predict driver route choice, and is typically applied in the assessment of road schemes. The authors have previously published an SUE (Stochastic User Equilibrium) assignment algorithm, i.e. one which models variation in driver perception, and cost variation due to congestion. The algorithm works by minimising a function given by Sheffi and Powell (1982); in this paper the three terms of the function are investigated separately, and the possibility explored of constructing more sophisticated versions of the SUE algorithm.
Abstract
Purpose
The purpose of this paper is to assess the orbital perturbation caused by the gravitational orbit–attitude coupling of spacecraft in the proximity of asteroids.
Design/methodology/approach
The gravitational orbit–attitude coupling perturbation (GOACP), which has been neglected before in the close-proximity orbital dynamics about asteroids, is investigated and compared with other orbital perturbations. The GOACP has its origin in the fact that the gravity acting on a non-spherical extended body is actually different from that acting on a point mass located at the body’s center of mass, which is the approximated model in the orbital dynamics. Besides, a case study of a tethered satellite system is given by numerical simulations.
Findings
It is found that the ratio of GOACP to the asteroid’s non-spherical gravity is the order of ρ/ae, where ρ is the spacecraft’s characteristic dimension and ae is the asteroid’s mean radius. It can also be seen that as ρ increases, GOACP will also increase but the solar radiation pressure (SRP) will decrease due to the decreasing area-to-mass ratio. The GOACP will be more significant than SRP at small orbital radii for a large-sized spacecraft. Based on the results by analyses and simulations, it can be concluded that GOACP needs to be considered in the orbital dynamics for a large-sized spacecraft in the proximity of a small asteroid.
Practical implications
This study is of great importance for the future asteroids missions for scientific explorations and near-Earth objects mitigation.
Originality/value
The GOACP, which has been neglected before, is revealed and studied.
