In the immediate post‐war years, school science apparatus was in short supply and the established manufacturers and supply houses provided very little in the way of new items. Criticism of the quality of available apparatus was frequently heard and was voiced in public at a particular A.G.M. of the Science Masters Association (now the ASE). This led in 1961 to a meeting (organised through the Scientific Instrument Manufacturers Association) between the principal manufacturers and a panel of HMIs. Whilst it was difficult for the latter to be specific about the shortcomings of apparatus on the market, it was suggested that SIMA should make contact with the then recently formed SMA Modern Physics Equipment Committee, which was concerning itself with the kind of new apparatus which would be required for teaching ‘modern physics’.

It is widely accepted that present‐day secondary school physics courses must include some ‘modern physics’, much of which is concerned with the atom and its structure. But, as J. L. Lewis has pointed out,

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.

This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.

This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.

The purpose of this study is to consider the effect of an internship experience on tax accountants’ professional performance.

It uses survival analysis, a dynamic methodology that allows for more precise modeling than static traditional methods used to study promotion and turnover rates in the past. The hypotheses were tested using a longitudinal database obtained from the human resource departments of regional Certified Public Accountant firms located in the southeastern and mid-south areas of the USA.

Results were mixed. As in previous studies on the effects of internships on subsequent professional performance, tax accounting professionals with a master’s degree and prior internship experience had significantly faster promotion rates than those professionals with a master’s degree and no internship experience. However, tax professionals with a master’s degree and prior internship experience did not demonstrate a significant difference in turnover rate when compared to the no-internship group.

This research provides evidence that students, employers and institutions of higher education can use to guide them in their decisions regarding the effects of structured internships on professional performance – in this case, the professional performance of tax accountants.

Previous research on tax professionals’ performance and internship experience made use of static research methodologies. This study uses the more dynamic methodology of survival analysis to see if different findings result.

ROUSED out of pre‐breakfast tea‐gulping torpor recently by hearing on Radio London the confident assertion, ‘Oh yes, there's a great shortage of librarians throughout the country…’ No Rip Van Winkle beard, wasn't April 1 and no echo of the Last Trump. It was all about a book called Work after work by Judy Kirby and REACH—Retired Executives Action Clearing House, which seeks to relieve the withdrawal symptoms of the retired by finding outlets for their skills in work for voluntary organisations. These withdrawal symptoms in librarians are easily recognised and include immediate and compulsive reading of everything in the Record, a tendency to beam for the first time at young people at conferences, and a not always suppressed urge to write rude letters to the professional press or to the LA. Editing the professional press is not recommended as nostrum for those old retirement blues.

Drawing on the literature on technological acquisition and the knowledge-based view , this study examines how technological overlap between acquiring and target firms influences acquisition premiums. We further explore how the resulting synergies are contingent on the dynamic characteristics of the target firm, specifically its technology clockspeed and industry munificence. Technology clockspeed indicates the pace of technological evolution, reflecting internal dynamic resources, while industry munificence represents the abundance of external resources. These boundary conditions illustrate the dynamics of synergies, explaining their moderation effects on acquisition premiums.

We analyze a sample of 369 technological acquisitions by publicly traded U.S. firms between 1990 and 2011. To test our hypotheses, we used the ordinary least squares regression model with robust standard errors clustered by acquiring firms. In the robustness checks, we applied the generalized estimating equations to account for non-independent observations in our sample and verified that the results were robust to an alternative two-way clustering approach.

We suggest that a low level of technological overlap between an acquiring firm and its target firm leads the acquiring firm to offer a high acquisition premium because of the expected synergistic potential that evolves from combining two distant technological bases. We further find that this effect is contingent on the target firm's technology clockspeed and industry munificence. Specifically, the negative effect is amplified when target firms exhibit a rapid pace of technological evolution, whereas it is weakened when target firms operate in highly munificent industries characterized by robust growth and abundant resource flows.

This study has several limitations, but it offers opportunities for future research. First, our sample is limited to domestic acquisitions between U.S. publicly traded firms, which may restrict generalizability. Cross-border acquisitions could reveal different dynamics, as technology leakage and national security concerns might make technological overlap a more sensitive factor. Additionally, private firms were not included, and their distinct strategic considerations could provide further insights. Future research could explore post-acquisition data to validate these synergies and expand the scope to include international contexts and private firms for a comprehensive analysis.

Our findings highlight important implications for managers in technology sector acquisitions. This study underscores the need for a thorough evaluation of target firms to avoid misjudging synergies. Low technological overlap can heighten expectations for value creation, making it crucial for executives to accurately assess potential synergies to prevent overestimation. Managers should consider both internal resources and external industry conditions when evaluating synergies. Ultimately, these insights help managers offer informed prices that reflect true strategic synergies, adopting effective valuation practices to mitigate risks of financial overpayments and poor post-merger performance.

The social implications of our findings emphasize the broader impact of acquisition decisions on innovation and competition within the technology sector. By ensuring accurate valuation and avoiding overpayment, companies can allocate resources more efficiently, fostering sustainable growth and innovation. This diligent approach can reduce the risk of corporate failures.

This study makes two key theoretical contributions. First, it identifies technological overlap as a critical determinant of acquisition premiums in technological acquisitions, addressing gaps in the literature that focused on CEO characteristics and managerial attention. Second, it expands the theoretical framework by highlighting the dynamic nature of synergies, influenced by the target firm's technology clockspeed and industry munificence. By integrating both acquiring and target firm characteristics, this study provides a relational perspective on value creation, explaining why firms pay high premiums and offering a more comprehensive understanding of the strategic motivations in technological acquisitions.

The aim of this research is to assess the role of mentoring as an approach to training and development for small‐ to medium‐sized enterprise (SME) retailers. Mentoring requires the teaming of a knowledgeable person with a learner, to enable a transfer of information, skills and expertise. Importantly it allows greater flexibility in the timing and location of learning. The research is being undertaken in the London Borough of Merton through an 18‐month project. This study forms an interim assessment and analysis of 40 retailers’ responses to the mentoring process, the types of learning needs encountered, the implementation of mentoring and their experiences and learning outcomes. It concludes by assessing the effectiveness of the initial outcomes of the project against its objectives and evaluating emerging themes in SME retail management.

The competition and regulatory economics literature has developed indicators that detect whether a vertically integrated provider (VIP) is engaging in market exclusion in the form of an anticompetitive price squeeze and non-price discrimination leading to sabotage of downstream competitors. Weisman integrates these indicators by developing a safe-harbor range within which a profit-maximizing VIP engages in neither form of market exclusion. Downstream retail competition that depends on the VIP’s inputs imposes upward pricing pressure on the downstream prices, with the amount of such pressure increasing as the downstream products become more homogeneous (closer substitutes). We analyze the implications of upward pricing pressure for antitrust evaluations of a duty to deal, regulatory policies mandating wholesale inputs for entrants, and vertical mergers. We find, for example, no basis to oppose a merger in which the VIP was previously required to supply inputs to rivals at unregulated prices.

Can children give their informed consent to participate in a research study, or can they only provide assent? This chapter explores this tricky question by drawing on three stages of a longitudinal ethnography within a multi-ethnic school in the north of England. Illustrative examples are used to show how the ability to give consent is not based on age alone, but rather on children’s experiences and confidence, the type of research conducted, and the researcher’s own expertise in communicating with children. The chapter provides examples of children’s active and ongoing negotiation of consent and through their choice to withdraw consent, ‘correct’ the researcher’s interpretations, actively produce their own written field notes and reflect on data collected as part of fieldwork. To facilitate consent, children were given time and space to familiarise themselves with the researcher and the study. Actively involving children in all stages of the study highlighted the importance of familiarisation and participation to the processes of informed consent to ensure children’s ongoing and meaningful involvement in the research.
