Reasoning Mind products are used by over 100,000 students a year and have shown positive outcomes. In this design case we focus on implementation: how Reasoning Mind’s approach evolved to tackle the challenge of achieving consistently high-quality implementations with many different schools, teachers, and students. Key insights include the definition of the Implementation Coordinator role and how that role is managed, the design and refinement of specific tools to support the implementation improvement process, and how Reasoning Mind’s understanding of its organizational values in relationship to its approach to implementation evolved over time. Based on a study in which 23 schools in West Virginia are newly adopting Reasoning Mind, we also reflect on how the design insights are playing out in a large-scale implementation.

This chapter presents a general approach to assessing the reliability of measurement of survey questions—those in common use in many surveys. The approach, which relies on a robust set of longitudinal design requirements, applies the quasi-Markov simplex model to multi-wave data in the evaluation of measurement errors for survey questions. Under particular assumptions, this model produces a set of estimates that conform to the psychometric definition of measurement reliability, defined as the ratio of true variance to observed variance. These models attribute some of the over-time inconsistency in measurements to unreliability and some to true change. This strategy rejects traditional notions of reliability that rely on internal consistency estimates for composite variables, as well as the simple test–retest approach to estimating reliability. Rather, the emphasis is on the separation of unreliability from true change in observations made over time. The importance of meeting several design requirements for using these over-time statistical models is also emphasized. These include the use of large-scale panel studies representative of known populations, with a minimum of three waves of measurement, separated by lengthy re-interview intervals, and limited to exactly replicated questions over the multiple waves. Results are presented from several three-wave panel studies that have employed this design, which provide evidence for the utility of the approach in the evaluation of the quality of survey measurement with respect to question content, context, and form.

Yurii Yaremenko was one of the late great theorists of the Soviet planning system. His theory, as presented first in censored and self-censored form in his major monograph, Structural Changes in the Socialist Economy (1981), describes the planned economy as composed of groups of technologically differentiated industries, ordered by their priority for receiving scarce high-quality goods. The forced development of the economy is its qualitative differentiation, which over time creates inherent structural imperatives for large-scale reorderings of that priority hierarchy, lest the phenomena of structural transformation become pathological. This account is supplemented by post-Soviet published interviews and by the author’s own interviews with Yaremenko’s associates. They reveal what Yaremenko’s theory left unsaid: that the disintegration of the late Soviet state into a multitude of competing, self-reproducing “administrative monsters,” the most powerful being the military industries distorted industrial structure, degraded civilian life, and ultimately made reform impossible.

Mode Of Production

Insects have been accepted as traditional food in many different cultures (Hanboonsong and Durst, 2014; Ramos-Elorduy 2009; Van Huis et al., 2013; Vantomme et al., 2004; Yen, 2009). A commonly accepted definition of ‘traditional’ is that it is a practice that has been operating in a particular culture for long historical periods and is passed through generations unchanged. We know that practices change over time, and the species composition of insects consumed by different cultures would not be exempt from change. Not only the kinds of insects used as food change, but the mode of production (whether they are collected in the wild, semi-domesticated or farmed) has also changed to ensure greater yields. Storage and cooking methods may also have changed. A recent example is the wider adoption of the introduced domestic cricket (Acheta domesticus) as a food in Thailand where native crickets have been consumed for many generations (Hanboonsong et al., 2013). While consumption of Orthoptera in Thailand may be considered traditional, the main species consumed has changed and the mode of production has changed with modern large scale farming techniques.

This chapter examines the difference between John Locke's definition of a person [P], considered as a kind of thing, and his definition of a subject of experience of a certain sophisticated sort [S]. It first discusses the equation [P] = [S], where [S] is assumed to be a continuing thing that is able to survive radical change of substantial realization, as well as Locke's position about consciousness in relation to [P]'s identity or existence over time as [S]. It argues that Locke is not guilty of circularity because he is not proposing consciousness as the determinant of [S]'s identity over time, but only of [S]'s moral and legal responsibility over time. Finally, it suggests that the terms “Person” and “Personal identity” pull apart, in Locke's scheme of things, but in a perfectly coherent way.

More than 95 % of the total housing stock in the Netherlands is connected to central sewerage systems and in most cases the wastewater is treated biologically. As connection to central sewerage systems has reached its economic limits, interest in on-site treatment of the domestic wastewater of the remaining premises is increasing. A large scale research programme into on-site wastewater treatment up to population equivalents of 200 persons has therefore been initiated by the Dutch Ministry of Housing, Physical Planning and Environment. Intensive field-research work did establish that the technological features of most on-site biological treatment systems were satisfactory. A large scale implementation of these systems is however obstructed in different extents by problems of an organisational, financial and/or juridical nature and management difficulties. At present research is carried out to identify these bottlenecks and to analyse possible solutions. Some preliminary results are given which involve the following ‘bottlenecks':-legislation: absence of co-ordination and absence of a definition of ‘surface water';-absence of subsidies;-ownership: divisions in task-setting of Municipalities and Waterboards; divisions involved with cost-sharing;-inspection; operational control and maintenance; organisation of management;-discharge permits;-pollution levy;-sludge disposal. Final decisions and practical elaboration of policies towards on-site treatment will have to be formulated in a broad discussion with all the authorities and interest groups involved.

Determining what should be considered a material item has been a problem for both the accounting profession and the courts. By reviewing the court cases involving the issue of materiality, the authors have determined where differences in the materiality standard as applied by the courts exist. The judicial definition of materiality has developed over time, and current trends with important variations are observed. Based upon the authors' analysis, the following judicial definition of materiality, with its possible variations, is suggested: Would the reasonable (or speculative) investor (or layman) consider important (or be influenced by) this information in determining his course of action?

An introduction to the mathematics of the Poisson random graph, the simplest model of a random network. The chapter starts with a definition of the model, followed by derivations of basic properties like the mean degree, degree distribution, and clustering coefficient. This is followed with a detailed derivation of the large-scale structural properties of random graphs, including the position of the phase transition at which a giant component appears, the size of the giant component, the average size of the small components, and the expected diameter of the network. The chapter ends with a discussion of some of the shortcomings of the random graph model.

What Matters

Humans use reasons to shape and justify choices. In the process, trade-offs seem essential and often inevitable. But trade-offs involve comparisons, which are problematic both across values and especially over time. Reducing disparate values to a common metric (especially if that metric is money) is often problematic and unsatisfactory. Critically, it is not that values just shape choices, but that choices themselves shape values. This endogeneity of values makes an unconditional normative endorsement of modern decision-theoretic rationality unwise. This is a hard problem and there is no escaping the definition of good values, that is, those that make humans better. This removes the wall between economics and philosophy. If we are to adopt and enact this perspective, then greater discourse and debate on what matters and not just what counts will be useful and even indispensable.

Urban Rail Transit Network

Hyperpaths enumeration is one of the basic procedures in many traffic planning issues. As a result of its distinctive structure, hyperpaths in Urban Rail Transit Network (URTN) are different from those in road network. Typically, one may never visit a station more than once and would never transfer from one line to another that has been visited in a loopless URTN, meaning that stations a hyperpath traversed cannot be repeated, neither do lines in loopless networks. This paper studies the relationships between feasible path and the shortest path in terms of travel costs. In this paper, a new definition of hyperpath in URTN is proposed and a new algorithm based on the breadth first searching (BFS) method is presented to enumerate the hyperpaths. The algorithm can safely avoid hyperpath omission and can even be applied in networks containing loops as well. The influence of parameters on hyperpaths is studied by experimentally finding hyperpaths in the subway network in Beijing. A group of suggested parameter pairs are then given. Finally, a numerical experiment is used to illustrate the validity of the proposed algorithm. The results imply the significance of the convergence of the BFS algorithm which can be used to search hyperpaths in large scale URTN even with loop.
