Abstract

Purpose

The C3 Framework is a recent example in a long history within the field of social studies education of efforts to engage teachers and students in inquiry-oriented teaching and learning. While there is some research regarding the efficacy of the inquiry design model (IDM) of the C3 Framework, few studies have sought to engage social studies teachers as coresearchers as they integrate the framework. This study addressed a persistent divide between the theory and practice of integrating inquiry in the social studies.

Design/methodology/approach

In this study, a classroom teacher and a university-based researcher conducted a hybrid action research study to understand the instructional shifts that occur as the C3 Framework is fully implemented into instruction.

Findings

Based on the findings, the authors present a theory of action to highlight key opportunities to shift instruction, while also acknowledging the factors that might mitigate those shifts. In particular, the authors focus on teacher decision-making and contextual factors that allow for and hinder the full integration of inquiry.

Originality/value

This study is unique in developing a hybrid action research/qualitative case study that provides insider knowledge related to improving social studies teaching and learning.

Abstract

Purpose and approach – We examine theoretically and experimentally how unequal abilities to contribute affect incentives and efficiency when players compete for membership in stratified groups based on the contributions they make. Players have either a low or a high endowment. Once assigned to a group based on their group contribution, players share equally in their group’s collective output. Depending on the parameters, the mechanism has several distinct equilibria that differ in efficiency.

Findings – Somewhat counter to conventional expectation our theoretical analysis indicates that as long as certain assumptions are satisfied, efficiency increases rather than decreases the more abilities to contribute differ. The analysis also suggests various follow-up experiments about equilibrium selection, tacit coordination, and the effect of unequal abilities in systems with endogenous grouping. We conduct an experiment that shows that subjects tacitly coordinate the mechanism’s asymmetric payoff-dominant equilibrium with precision; this precision is robust to a change in the structure and complexity of the game.

Implications – The results suggest that people respond to merit-based grouping in a natural way and that competitive contribution-based grouping encourages public contributions even when abilities to contribute differ, which is the case in all communities and societies.

Abstract

Purpose

In both elementary schools and elementary teacher education programs, social studies is marginalized while standards require increasingly more ambitious reasoning, reading, and writing in social studies than has historically been documented in American elementary schools. The purpose of this paper is to explain the challenges that elementary social studies teacher educators face in preparing elementary school teachers to facilitate the kind of ambitious social studies envisioned in the NCSS’s C3 Framework and advocate an approach to successfully address these challenges.

Design/methodology/approach

This paper articulates a targeted and ambitious approach to elementary social studies teacher education. The authors describe five recommendations from the teacher education literature for supporting preservice teachers in learning disciplinary-oriented social studies teaching, recommendations that guided the redesign of the social studies methods course. The authors then highlight key aspects of the redesigned methods course and demonstrate how the authors engaged the challenges inherent in the work of elementary social studies teacher education.

Findings

Although this paper is not arranged in such a way as to substantiate empirical findings, the purpose of the paper is to demonstrate an approach to elementary social studies education aligned with extant literature on preparing teachers to engage in reform teaching practices, specifically those disciplinary oriented practices suggested in NCSS’s C3 Framework. As such, the paper should be read as a perspective on practice.

Research limitations/implications

The type of disciplinary-oriented approach described here is increasingly under investigation in secondary teacher education research and similar approaches are under investigation in elementary math and science education research. To the authors’ knowledge, the approach is novel in elementary social studies education. Furthermore, the authors believe it offers a direction for researchers interested in gaps in the literature related to practice based teacher education and disciplinary-oriented social studies teacher education.

Practical implications

The approach described here offers specific guidance and resources for teacher educators who are struggling with the challenges of the contemporary social studies education landscape and/or who wish to focus methods courses in disciplinary ways.

Social implications

Research in social studied education has demonstrated that when students are exposed to disciplinary practices in social studies, their literacy skills improve and they learn analytical skills that support their development as citizens (consumption of media, participation in public discourse, ability to discern arguments).

Originality/value

As noted above, the approach described here is novel in elementary social studies education. Combining a disciplinary approach with a practice-based frame in elementary social studies represents an opportunity for empirical research and offers new approaches to the practice of teacher education and early career professional development.

This paper aims to evaluate the longer-term impact of the 12-month Welsh clinical leadership fellowship.

Abstract

Purpose

This paper aims to evaluate the longer-term impact of the 12-month Welsh clinical leadership fellowship.

Design/methodology/approach

Semi-structured interviews with 10 out of 14 trainee doctors who were fellows between 2013-2016, exploring how leadership knowledge and skills were used in clinical practice, impact on patient care and influence on careers. Data, gathered in 2017 when participants had completed the fellowship between 1-3 years, were analysed thematically.

Findings

All found the fellowship rewarding. The experience was felt to advantage them in consultant interviews. They gained insight into the wider influence on organisations and the complexity of issues facing senior clinicians. Although subtle, the impact was significant, equipping fellows with negotiation skills, enabling them to better influence change. Indirect impact on clinical practice was evidenced by enhanced confidence, teamworking skills and progression of improvement projects. However, the use of skills was limited by lack of seniority within teams, demands of medical training and examinations. The negativity of others towards management and leadership was also noted by some.

Research limitations/implications

Small participant numbers limit generalisability.

Practical implications

The fellowship is designed to equip participants with skills to lead improvements in healthcare delivery. Those more advanced in their medical training had greater opportunity and seniority to lead change and were better placed to apply the learning. This has implications for whom the training should be targeted.

Originality/value

A rare study exploring the longer-term impact of a leadership programme on later clinical practice, which adds to the body of knowledge of impact and efficacy of leadership training programmes in healthcare environments.

Abstract

Purpose

The purpose of this paper is to evaluate and compare the effectiveness and sensitivity of different cleanliness verification tests for post soldered printed circuit board assemblies (PCBAs) to provide an understanding of current industry practice for ionic contamination detection limits.

Design/methodology/approach

PCBAs were subjected to different flux residue cleaning dwell times and cleanliness levels were verified with resistivity of solvent extract, critical cleanliness control (C3) test, and ion chromatography analyses to provide results capable of differentiating different sensitivity levels for each test.

Findings

This study provides an understanding of current industry practice for ionic contamination detection using verification tests with different detection sensitivity levels. Some of the available cleanliness monitoring systems, particularly at critical areas of circuitry that are prone to product failure and residue entrapment, may have been overlooked.

Research limitations/implications

Only Sn/Pb, clean type flux residue was evaluated. Thus, the current study was not an all encompassing project that is representative of other chemistry‐based flux residues.

Practical implications

The paper provides a reference that can be used to determine the most suitable and effective verification test for the detection of ionic contamination on PCBAs.

Originality/value

Flux residue‐related problems have long existed in the industry. The findings presented in this paper give a basic understanding to PCBA manufacturers when they are trying to choose the most suitable and effective verification test for the detection of ionic contamination on their products. Hence, the negative impact of flux residue on the respective product's long‐term reliability and performance can be minimized and monitored effectively.

To evaluate the effect of synthesised calixarenes as new inhibitors on the corrosion of steel in HCl media at various temperatures.

Abstract

Purpose

To evaluate the effect of synthesised calixarenes as new inhibitors on the corrosion of steel in HCl media at various temperatures.

Design/methodology/approach

Calixarenes have been synthesised and tested as corrosion inhibitors. Gravimetric technique and potentiodynamic polarisation and impedance spectroscopy methods were used.

Findings

Calixarenes exhibited a good inhibition. Their efficiency decreases slightly with temperature.

Research limitations/implications

It was found that the inhibition efficiency increases with the concentration of inhibitors to reach 92 per cent at 10−4M.

Practical implications

The efficiency of calixarene derivatives increases with the concentration and falls slowly with temperature to attain 84 per cent at 353 K range. Calixarenes can be used in chemical cleaning and pickling processes.

Originality/value

The originality of this work is to find an inhibitor to give protection close to 100 per cent.

Abstract

Purpose

In responding to competitors' strategic choices, firms must choose whether to allocate their customer relationship management (CRM) resources primarily to retaining existing customers or to acquiring new customers. To address this critical but understudied question, the authors examine the strategic choices of two competing firms between retention- and acquisition-focused strategies in consideration of switching costs, technological advancement level, and market share.

Design/methodology/approach

The authors develop and analyze a game-theoretic model to investigate the strategic choices of two competing firms between retention- and acquisition-focused strategies.

Findings

When switching costs are high, findings show that when the degree of technological advancement is high (low), both firms should employ acquisition-focused (retention-focused) strategies to maximize their profits. When switching costs are low and there are a low degree of technological advancement and asymmetric market shares, the firms choose retention-focused strategies in equilibrium, but only the firm with the higher market share can maximize its profit. When switching costs are low, technological advancement levels are high, and the market shares are asymmetric, the firm with the higher market share chooses a retention-focused CRM strategy, while the rival with lower market share adopts an acquisition-focused strategy in equilibrium. However, neither firm can maximize its profits.

Originality/value

Prior research focused on a single firm's price discrimination decision without considering a competitor's strategic choice. To address this research gap, the authors examine where firms should assign their CRM resources (retention vs. acquisition) in response to a competitor's CRM strategy. This study provides guidance for optimal decision-making regarding a firm's CRM resource allocation in a duopoly market.

Abstract

Using a two bank, two-period game-theoretic model, this chapter shows that contingent purchase and assumption policy under which the choice of acquirer for a failed bank is contingent on the surviving banks’ risk-taking behavior is generally most effective in reducing moral hazard problems, particularly for countries with low levels of competition and high regulatory barriers. Moreover, we find that to minimize the probability of future bank failures, the choice of acquiring bank should be based not only on the short-term goal of resolving the insolvencies of financial institutions, but also on the long-term effects of ex ante risk-taking incentives.
