Abstract

Recent surveys have shown that between 20 per cent to 40 per cent of teachers experience considerable stress when working in schools. Following a summary of research into the sources and correlates of reported teacher stress, this paper proposes a definition and a model of work‐related stress in school that incorporates current concepts and research findings. Examples of tactics and strategies for coping with and reducing the build‐up of environmental stressors are developed from the model. These aim to provide pointers for the multi‐level management of stress throughout schools.

Abstract

Purpose

The goal of this study was to investigate the co-citation of information security patents in the United States Patent and Trademark Office (USPTO) database.

Design/methodology/approach

This research is a scientometrics study that has been conducted using the co-citation analysis. The statistical population of the present study includes all patents of information security filed in the USPTO database from 1971 to 2015. As a result of this search, 30,736 patents were retrieved. In this investigation, UCINET software and its complementary package (NetDraw) were employed to plot scientific maps.

Findings

The findings of this study indicated an upward trend of patents in the field of information security between 1971 and 2015. The “California State” has the top world rank in information security inventions, followed by “Japan” and the “Washington State.” “VAN WIE, DAVID M” is the most cited inventor in the field of information security. The analysis of inventors' co-citation data indicated that “ADAMS, NEIL- LITTLE” and “HERBERT ANTHONY” had the highest co-citation rates with each other and were ranked first. The survey of high-citation inventors based on centrality indices indicated that “LEACH, PAUL J” graded first in degree centrality, “BENALOH, JOSH D” in betweenness centrality and “BENALOH, JOSH D” in closeness centrality.

Originality/value

The co-citation analysis of patents can show the most important patents and the relationships between them. Such analyses can be useful for large-scale policymaking or identification of existing gaps and attempting to address them.

Abstract

New educators may feel overwhelmed by the options available for engaging students through classroom participation. However, it may be helpful to recognize that participatory pedagogical systems often have constructivist roots. Adopting a constructivist perspective, our paper considers three meta-practices that encourage student participation: designing activities, leading others, and assessing peers. We explored the consequences of these meta-practices for important student outcomes, including content knowledge, engagement, self-efficacy, sense of community, and self-awareness. We found that different meta-practices were associated with different combinations of outcomes. This discovery demonstrates the benefit of studying meta- practices so as to reveal the nuanced effects that may arise from pedagogical choices. In addition, an understanding of meta-practices can help leadership educators to be more discerning and intentional in their course designs.

Abstract

This paper examines the clustering of return volatility within industries by comparing the short‐run responses of stock returns to the arrival of macroeconomic news across several industries. We hypothesize that some industries have distinctive qualities which influence the sensitivity of companies’ equity value to information releases. To test this hypothesis, we sample intraday stock price data of ten firms from three industries ‐ General Industry, Banking, and Real Estate Trusts ‐ and conduct the Brown‐Forsythe‐Modified Levene tests. The evidence shows that there exist different degrees of responses to the release of macroeconomic news and consequently different degrees of return volatility clustering: strongest in General Industry, less strong in Banking, and weak in Real Estate Investment Trusts.

Abstract

Many of the difficulties that have been experienced by Health Authorities in this country in the examination of imported butcher's “offal”—using the term “offal” in its trade sense—would seem to have been due to injudicious methods of packing on the other side. The organs that constitute “offal”—livers, plucks, kidneys, sweetbreads, and so forth—have hitherto been closely packed into a bag, box, or crate, and the whole mass then frozen hard. Hence on arrival at the port of inspection the separate examination of these organs for possible disease conditions was rendered a matter of extreme difficulty. The exporters have now, it appears, almost all arranged for the separate freezing of the larger organs before packing, and in the case of smaller organs, such as kidneys and sweetbreads, some packers now make use of shallow boxes.

Abstract

Purpose

Boric acid has been used for many years as a catalyst inhibitor and crosslinking agent to increase the glass transition temperature of epoxy resins for printed circuit boards (PCB), as well as in the glass fibre reinforcement. Recent regulation related to boric acid and its salts by the ECHA, a regulatory agency in the EU, may limit the use of these materials. The purpose of this paper is to describe the implications of this new regulation and to propose an analytical procedure that is relevant to PCB's.

Design/methodology/approach

Potential analytical procedures, including dissolution in acid and aqueous extraction followed by boric acid titration, are discussed and evaluated.

Findings

The use of acid for the digestion of prepreg, laminates and PCBs has the potential to greatly overstate the concentration of boric acid in PCBs.

Originality/value

An aqueous extraction method (German DIN 38414‐4) gives results that represent a worst‐case leaching process. It is proposed that it becomes the official analytical method for printed circuit boards in order to comply with the ECHA regulation.

Abstract

Globally, urban planners and decision makers are pursuing place-based initiatives to develop and enhance urban infrastructure to optimise city performance, competitiveness and sustainability credentials. New discourses associated with big data, Building Information Modelling, SMART cities, green and biophilic thinking inform research, policy and practice agendas to varying extents. However, these discourses remain relatively isolated as much city planning is still pursued within traditional sectoral silos hindering integration. This research explores new conceptual ground at the Smart – Natural City interface within a safe interdisciplinary opportunity space. Using the city of Birmingham UK as a case study, a methodology was developed championing co-design, integration and social learning to develop a conceptual framework to navigate the challenges and opportunities at the Smart-Natural city interface. An innovation workshop and supplementary interviews drew upon the insights and experiences of 25 experts leading to the identification of five key spaces for the conceptualisation and delivery at the Smart-Natural city interface. At the core is the space for connectivity; surrounded by spaces for visioning, place-making, citizen-led participatorylearning and monitoring.The framework provides a starting point for improved discussions, understandings and negotiations to cover all components of this particular interface. Our results show the importance of using all spaces within shared narratives; moving towards ‘silver-green’ and living infrastructure and developing data in response to identified priorities. Whilst the need for vision has dominated traditional urban planning discourses we have identified the need for improved connectivity as a prerequisite. The use of all 5 characteristics collectively takes forward the literature on socio-ecological-technological relationships and heralds significant potential to inform and improve city governance frameworks, including the benefits of a transferable deliberative and co-design method that generates ownership with a real stake in the outcomes.

Abstract

The 28th annual conference of Aslib, held at Nottingham University from 11th to 14th September, 1953, proved to be the largest that Aslib has so far organized. A list of those present is printed on pp. 254–260. Yet again Aslib was glad to be able to welcome a number of overseas guests and members, including Dr. and Mrs. Lancour and their small daughter from the U.S.A., Drs. and Mrs. van Dijk and Miss Rom from the Netherlands, Mr. M. S. Dandekar and Mr. J. V. Karandikar from India, Miss D. M. Leach from Canada, and Mrs. T. Collin from Norway. Mr. Walter A. Southern, a Fulbright scholar from the U.S.A. affiliated to Aslib during his year's study in the United Kingdom, represented the Special Libraries Association, and Mr. J. E. Holmstrom attended as an observer on behalf of Unesco.
