Press releases are a major means of communication between the government and the public, and yet they remain an under‐rated and neglected source of data. This paper describes the functions fulfilled by press releases and seeks to evaluate their potential value to the information professions and to researchers by means of interviews with the press officers of two major government departments and two quangos.

Much research has been reported on the possibilities of using various heuristic priority rules to sequence batches through a job shop. The SPT (Shortest Priority Time) heuristic, or modifications to it, has been proved useful in many studies. This paper reports on the results obtained when simulating the work flow through a real machine shop. The simulation model has been used to test the effect on well known priority rules of releasing batches into the shop in order of decreasing expected throughput time. The important effect of this “phased release” of batches was to increase the percentage of batches delivered in finished parts stores on time, particularly in the case where priority rules were in use which might otherwise have resulted in poor delivery. This has important repercussions for management because it implies that by “phased” release of batches in the manner discussed, a large proportion of batches will be delivered on time whatever priority rule is in operation in the shop.

This article was prompted by the recent stimulating report in this journal of a controlled study of block release and day release courses made during the 1963–64 session in the Department of Engineering, Building and Agriculture, Whitwood Mining and Technical College.

Purpose – New genetically modified (GM) crops are novel but risky interventions, offering a variety of potential benefits but also the possibility of serious unintended consequences. I address the regulatory framework for GM crops, seeking protection from disproportionate risks without unduly stifling innovation.

Approach – Conditions that may justify precautionary interventions are identified, and an idealized regulatory protocol (screening, pre-release testing, and post-release surveillance, STS) is developed to provide protection, encourage research and learning, and focus-in quickly on the cases that pose serious threats of harm. This protocol is adapted to the case of GM crops, and compared with current regulatory practice in the United States, the EU, and Canada, as well as international agreements exemplified by the Cartagena Protocol on Biosafety. Two real-world cases are considered, Starlink® corn and Roundup-Ready® canola, and some speculations are offered as to how the stylized protocol might have handled them.

Findings for policy – Pre-release, US regulatory practice is more fragmented and incomplete than the stylized protocol; EU practice is more systematic and streamlined, but some critics perceive over-regulation; and Canadian regulatory practice is more consistent with the protocol. Only the EU performs systematic post-release surveillance. International agreements have various weaknesses, beginning with fragmentation: for example, food safety and biosafety are regulated separately.

Implications for further research – Embracing the STS framework opens a broad new avenue of research about to how the mix of pre-release testing and post-release surveillance might be streamlined to provide adequate protection while reducing further the costs and delays entailed.

The problem of missing children draws much attention of both governmental and nongovernmental organizations in China due to huge numbers of the missing children. According to the records of Baby Back Home network (BBHNet), a professional website to search missing children in China, 1,666 missing children have been found via releasing information on BBHNet; however, there are still 30,561 families searching for their children and 24,603 missing children are searching for biological parents through this website and have not succeeded yet. What is the difference between successful and unsuccessful cases in the aspect of released information? Motivated by this question, our research proposes to determine the crucial information in the process of searching missing children. A logistic regression model was developed on the data summarized from 500 succeed cases and 500 cases which have not succeed yet from BBHNet for forecasting success rate of searching missing children. The model identifies that the differences in terms of released information, number of children, address, and natural geographical features are the three most crucial factors that cause differences in the result of searching. This research can be used as a guide for improving the success rate of searching missing children and provide reference for developing a missing children information-sharing platform.

Following in the footsteps of critics of the 1920s and 1930s, Caleb Foote's 1954 study of the bail system in Philadelphia set the agenda for bail reform in the United States focusing on judicial discretion and the inequities of a predominantly financially based pretrial detention system. This article argues that the bail reform movement originating in the 1960s fell short of its objectives in its failure to engage judges in the business of reform. From Foote's study on, Philadelphia has played a role historically in studies of bail, detention, and reform. The article considers the experience of Philadelphia's judicial pretrial release guidelines innovation from the 1980s to the present and its implications as an important contemporary bail reform strategy in addressing the problems of bail, release, and detention practices. The implications of the judge-centered pretrial release guidelines strategy for addressing pretrial release problems in urban state court systems are discussed in light of the original aims and issues of early bail reform.

To provide human judgment input for computer algorithm development, this study examines the relative importance of source, content, and style cues in predicting the truthfulness ratings of two common types of online health information: news stories and institutional news releases.

This study employed a multi-method approach using (1) a manual content analysis of 400 randomly selected online health news stories and news releases from HealthNewsReview.org and (2) an online experiment comparing truthfulness ratings between news stories and news releases.

Using content analysis, the authors found significant differences in the importance of source, content, and style cues in predicting truthfulness ratings of news stories and news releases: source and style cues predicted truthfulness ratings better than content cues. In the experiment, source credibility was the most important predictor of truthfulness ratings, controlling for individual differences. Experts have higher ratings for news media stories than news releases and lay people have no differences in rating the two news formats.

It is important for health educators to curb consumer trust in misinformation and increase health information literacy. Rather than solely reporting scientific evidence, educators should focus on addressing cues people use to judge the truthfulness of health information.

This is the first study that directly compares human judgments of health news stories and news releases. Using both the breadth of content analysis and experimental causality testing, the authors evaluate the relative importance of source, content, and style cues in predicting truthfulness ratings.

Most prisoners are eventually returned to their communities, making their transition into the community and aftercare a fundamental aspect of successful re-entry. This paper aims to explore the stages of someone’s reintegration from pre-release, through to reintegration and desistance and consider the factors relevant to the re-entry process for those who have offended and how to enhance this process. The aim of this paper was twofold; first to highlight the various factors and issues involved in the re-entry and reintegration process, particularly for those who are released after imprisonment and, second, to consider the significance of aftercare services in facilitating this process.

This paper opted for a brief review of the literature regarding incarceration and reintegration and some of the gaps in the literature. This paper will commence with a discussion of the effects of imprisonment on those who are incarcerated, then a consideration of the re-entry process, followed by a discussion of the reintegration process and desistance. Following will be reflections regarding the implications for practice. A case study is used to illustrate these points.

The current paper proposes a framework by which organisations and service providers working with those who are released from prison can use or incorporate into their practice to enhance aftercare support. The case study is used as an example to further illustrate this.

Implications for practice are also considered as well as recommendations to aid the re-entry and aftercare process. Suggestions are also offered to those agencies that are responsible for the provision of aftercare services for those released from prison.

This paper offers some considerations regarding the importance of the preparing and planning for release with a specific focus on aftercare services and their role in the re-entry and reintegration process.

This study aims to examine the impact of managerial ability on the total amount of chemical releases reported to the Toxics Release Inventory (TRI) at the US Environmental Protection Agency.

Regression analysis is used to examine the association between managerial ability and chemical releases.

A negative relationship was found between managerial ability and TRI’s chemical releases, suggesting that more-able managers better reduce TRI’s chemical releases, relative to less-able managers.

By providing useful insights into what determines TRI’s chemical releases, this study should interest policy makers and practitioners.

This study contributes to and links two research schools: managerial ability in management literature and corporate social responsibility (i.e. pollution prevention) in the broad business literature. To the best of the author’s knowledge, this is the first empirical study that performs a direct test of the association between managerial ability and TRI’s toxic chemical releases.

The use of software is overpowering our modern society. Advancement in technology is directly proportional to an increase in user demand which further leads to an increase in the burden on software firms to develop high-quality and reliable software. To meet the demands, software firms need to upgrade existing versions. The upgrade process of software may lead to additional faults in successive versions of the software. The faults that remain undetected in the previous version are passed on to the new release. As this process is complicated and time-consuming, it is important for firms to allocate resources optimally during the testing phase of software development life cycle (SDLC). Resource allocation task becomes more challenging when the testing is carried out in a dynamic nature.

The model presented in this paper explains the methodology to estimate the testing efforts in a dynamic environment with the assumption that debugging cost corresponding to each release follows learning curve phenomenon. We have used optimal control theoretic approach to find the optimal policies and genetic algorithm to estimate the testing effort. Further, numerical illustration has been given to validate the applicability of the proposed model using a real-life software failure data set.

The paper yields several substantive insights for software managers. The study shows that estimated testing efforts as well as the faults detected for both the releases are closer to the real data set.

We have proposed a dynamic resource allocation model for multirelease of software with the objective to minimize the total testing cost using the flexible software reliability growth model (SRGM).
