This paper examines the empirical patterns of futures prices volatility by using different seasonal adjustment techniques The average absolute month to month percentage (AAPC) figures are used to describe the extent of smoothness when seasonal adjustment methods are applied. Several interesting patterns are suggested from the observation of different futures contracts. The authors then suggest further that if seasonal patterns do exist for futures prices volatility, it is possible to focus the study of futures prices volatility on the different seasonal filters selection, and/or on the different seasonal models alternatives.

The purpose of this paper is to demonstrate how probabilistic simulation can be used to assist prospective general partners (GP) and limited partners (LP) of a venture capital limited partnership fund to evaluate alternative investment strategies for the proposed fund. The model presented in the paper is based upon observed characteristics of the venture capital market reported in the finance, economics, and management science literature. The body of the paper is organized as follows. In Section II we review the structural characteristics of the model. In Section III we present the results, in terms of ending wealth, obtained from simulating the fund's operations over its life under selected alternative investment strategies. In Section IV we show evaluations of the fund's simulated results under expected return, mean/variance and four moment approaches. In Section V, we present conclusions and implications of the results for financial management.

This article explores the neglected issue of the overrepresentation in the child protection system of children from ethnic, cultural, religious, racial, and linguistic minorities. It focuses on the accommodation of children’s diverse backgrounds within the s 31(2) threshold and s1 “best interests” stages of intervention under the Children Act 1989. First, it introduces the ethnic child protection penalty as a new tool for capturing the complex nature of overrepresentation of these children. Second, it proposes a framework for understanding the judicial approach in higher court decisions on the current extent and nature of accommodation. Third, it employs the penalty concept to help explain why case law analysis reveals difficulties with the current factor-based approach, whereas empirical research suggests generally satisfactory accommodation in practice. It concludes by proposing a contextualized framework for decision-making in relation to child protection.

Purpose – The purpose of this chapter is to consider the historical context of the gradual release model as it emerged following the early twentieth century emphasis on behaviorism as psychologists (and reading researchers) increasingly focused on cognition in the reading process. This “cognitive turn” in educational psychology was followed closely by a “social turn” with its focus on the socially constructed nature of texts, learning, and reading, particularly influenced by Vygotsky and work on scaffolding.

Design/methodology/approach – This chapter uses literature from the field to contextualize the gradual release of responsibility (GRR) model and to discuss research or practice chapters included in this edited volume.

Findings – This chapter described the transition from behaviorism to cognition to social construction as it applies to the reading process generally and to GRR in particular. It noted that this transition has required teachers to be more nimble and flexible than ever before, cautioned that the complexity of classroom life and the pressures on teachers can cause techniques such as GRR to be misused, and suggested ways to manage the group work which is central to social cultural approaches to literacy. And along the way it spotlighted the ever-widening range of applications of the GRR documented in the earlier chapters of the book.

Practical implications – The section in this chapter with most immediate practical implication is clearly the section on misuses of the GRR model. This section discusses some misuses of the model: neglecting explicit teaching; missing the middle (i.e., jump from explicit teaching directly to independent practice); and applying in an overly rigid manner.

Originality/value of paper – This chapter makes an original contribution to the field in providing a historical context for the gradual release model and for addressing the chapters in this edited collection. The authors also point to some areas for next steps forward as reminders to those applying the model.

This chapter sets out a descriptive account of the various legal claims for reparations, including the theories involved and the history of reparations lawsuits. It describes the major reparations cases, the arguments used in these cases, and the court decisions. It also discusses the evolution of legal theories for reparations as well as other attempts to secure compensation.

I examine the case law and the significant court rulings, as well as the discussion within secondary literature regarding these legal claims. I also examine other reparations advocacy approaches, including H.R. 40 and official apologies.

Reparations lawsuits have been brought against both government and private defendants, employing both tort and unjust enrichment theories. However, these suits have failed due to a variety of legal hurdles, including statutes of limitations, standing, and causation. The failure of reparations lawsuits illustrates the limitations of the legal system in addressing mass harms.

This chapter summarizes in relatively brief and generalist-accessible form the history and current status of legal claims for reparations.

The demand for including enterprise in the education system, at all levels and for all pupils is now a global phenomenon. Within this context, the use of competitions and competitive learning activities is presented as a popular and effective vehicle for learning. The purpose of this chapter is to illustrate how a realist method of enquiry – which utilises theory as the unit of analysis – can shed new light on the assumed and unintended outcomes of enterprise education competitions. The case developed here is that there are inherent flaws in assuming that competitions will ‘work’ in the ways set out in policy and guidance. Some of the most prevalent stated outcomes – that competitions will motivate and reward young people, that they will enable the development of entrepreneurial skills, and that learners will be inspired by their peers – are challenged by theory from psychology and education. The issue at stake is that the expansion of enterprise education policy into primary and secondary education increases the likelihood that more learners will be sheep dipped in competitions, and competitive activities, without a clear recognition of the potential unintended effects. In this chapter, we employ a realist-informed approach to critically evaluate the theoretical basis that underpins the use of competitions and competitive learning activities in school-based enterprise education. We believe that our findings and subsequent recommendations will provide those who promote and practice the use of competitions with a richer, more sophisticated picture of the potential flaws within such activities.
