Previous research on classroom uses for political cartoons identified two negative trends: creative stagnation (as teachers utilized them solely for interpretation) and age limitation (as researchers suggested they fit best with gifted and older students). Recent scholarship has addressed both trends by enabling young adolescent students to creatively express newly generated understandings through construction of original political cartoons. During such authentic assessment activities, students demonstrated high levels of criticality by using effective and efficient technologies to create original political cartoons, which then elicited constructive whole class interpretative discussions. This prior research did not detail specific methodological steps that positively influenced students’ original political cartoons. This paper compares students’ original political cartoons generated from two methodological approaches that differ in two small, yet consequential steps. One teacher required students to utilize concept maps and substitution lists prior to original political cartoon construction while the other did not. Based on the collected data, these two steps enabled the former teacher’s students to more effectively incorporate intricate and complex encoded messages through the use of abstract symbolism and complementary textual statements. The findings prove meaningful for teachers and researchers interested in enabling students’ creative and critical expressions of historical thinking.

An increasing volume of historical text is being converted into machine‐readable form so as to allow database searches to be carried out. The age of the material in these databases means that they contain many spellings that are different from those used today. This characteristic means that, once the databases become available for general online access, users will need to be familiar with all of the possible historical spellings for their topic of interest if a search is to be carried out successfully. This paper investigates the use of computational techniques that have been developed for the correction of spelling errors to identify historical spellings of a user's search terms. Two classes of spelling correction method are tested, these being the reverse error and phonetic coding methods. Experiments with words from the Hartlib Papers Collection show that these methods can correctly identify a large number of historical forms of modern‐day word spellings.

Because increasing product variety in retail conflicts with limited shelf space, managing assortment and shelf quantities is a core decision in this sector. A retailer needs to define the assortment size and then assign shelf space to meet consumer demand. However, the current literature lacks not only information on the comprehensive structure of the decision problem, but also a decision support system that can be directly applied to practice in a straightforward manner. The paper aims to discuss these issues.

The findings were developed and evaluated by means of explorative interviews with grocery retail experts. An optimization model is proposed to solve the problem of assortment planning with limited shelf space for data sets of a size relevant in real retail practice.

The author identifies the underlying planning problems based on a qualitative survey of retailers and relates the problems to each other. This paper develops a pragmatic approach to the capacitated assortment problem with stochastic demand and substitution effects. The numerical examples reveal that substitution demand has a significant impact on total profit and solution structure.

The author shows that the model and solution approach are scalable to problem sizes relevant in practice. Furthermore, the planning architecture structures the related planning questions and forms a foundation for further research on decision support systems.

The planning framework structures the associated decision problems in assortment planning. An efficient solution approach for assortment planning is proposed.

This paper is grounded on the premise that effective educators base lessons on rich and intriguing content which is relevant to students’ lives, implement the content using engaging and age-appropriate methodology, and measure students’ learning through authentic assessments. In order to support practicing teachers’ effective implementation of best practice methodology and assessment, educational researchers investigate the interconnections between content, methodology, and assessment. As technology facilitates teaching methodologies and learning assessments, meaningful activities such as students’ original political cartooning should be examined, detailed, and adapted. In this article, the methodological suggestions for, and adaptations of, students’ original political cartoons guide educators who seek to enable students’ creative and critical expressions of understandings about complex historical content.

TO make alloy steel we draw almost entirely upon material from outside the United States. We produce our own molybdenum. Our nickel comes from Canada and so does a part of our copper. Manganese and chromium are nearly all imported. We produce some tungsten and substantial amounts of vanadium. Tin, columbium and other vital materials are imported.

The purpose of this paper is to examine the extent to which corporate board characteristics influence the level of dividend pay-out ratio using a sample of UK small- and medium-sized enterprises from 2010 to 2013 listed on the Alternative Investment Market.

The data are analysed by employing multivariate regression techniques, including estimating fixed effects, lagged effects and two-stage least squares regressions.

The results show that board size, the frequency of board meetings, board gender diversity and audit committee size have a significant relationship with the level of dividend pay-out. Audit committee size and board size have a positive association with the level of dividend pay-out, whilst the frequency of board meetings and board gender diversity have a significant negative relationship with the level of dividend pay-out. By contrast, the findings suggest that board independence and CEO role duality do not have any significant effect on the level of dividend pay-out.

This is one of the first attempts at examining the relationship between corporate governance and dividend policy in the UK’s Alternative Investment Market, with the analysis distinctively informed by agency theoretical insights drawn from the outcome and substitution hypotheses.

Currently, most research studies focus on ownership reforms and governance reforms, while only a few research studies focus on management system innovations. Based on an evolution of state-owned enterprises’ (SOEs) performance appraisal systems, this paper investigates the influence of performance appraisal system on earnings management.

Using a natural experiment that central government-owned enterprises (CGOEs) carried out economic value-added performance appraisal (EVA-PA) in 2010, the authors adapt difference-in-difference method to analyze the relationship between EVA-PA and earnings management choice. Furthermore, the authors consider the situation which contained financial status, separation between decision-making rights and decision-control rights, separation between ownership and control and industrial characteristics.

The research finds that after carrying out EVA-PA, CGOEs prefer accrual-based earnings management to real earnings management, and there is substitution effect between the two types of earnings management. Moreover, further research studies reveal that enterprises suffering losses in the previous year and featuring higher separation between decision-making rights and decision-control rights and higher separation between ownership and control have stronger earnings management motive under EVA-PA. In contrast, enterprises achieving satisfactory financial performance in the previous year and engaging in businesses within protective industry have weaker earnings management motive under EVA-PA. After the implementation of EVA-PA, accrual-based earnings management and real earnings management both impair operating performances of CGOEs.

Theoretically, this paper enriches research studies on earnings management from the perspective of incentive mechanism and expands research studies on economic consequences of EVA-PA. In addition, it validates the relationship between the two types of earnings management. As an important mechanism of corporate management and control, performance appraisal system is an important part for establishing ownership management system and improving internal management system of SOEs.

Three approaches to the problem of determining buffer stocks to protect against uncertainty in product mix are presented. Each approach can be adapted to recognise the total cost, rather than the total size of component safety stock. Uncertainty in product mix arises because of forecast errors within the total manufacturing lead time. This may be too short to allow for changes in volume but the creation of component safety stock will permit changes of product mix. Examples of the approaches described are given.

This chapter is an up-to-date survey of the state-of-the art in consumer demand analysis. We review (and evaluate) advances in a number of related areas, in the spirit of the recent survey paper by Barnett and Serletis (2008). In doing so, we only deal with consumer choice in a static framework, ignoring a number of important issues, such as, the effects of demographic or other variables that affect demand, welfare comparisons across households (equivalence scales), and the many issues concerning aggregation across consumers.
