Abstract Jan David’s Duodecim specula (Antwerp: Officina Plantiniana, 1610) is a meditative emblem book, centred around myriad mirror metaphors. However, it also contains various depictions of ‘real’ optical instruments, such as lenses and concave mirrors, which have not yet been studied as such. This article explores how catoptrics and dioptrics (optical reflection and refraction) inform the meditative programme laid out in Duodecim specula. In the emblems and text, it will be argued, Jan David relies on a type of public knowledge of optics, which he expected the reader to possess. By tapping into this reservoir of optical knowledge and adding onto it, the book stimulates the affective reading process and hands the reader concrete tools for performing the meditative programme.

Purpose This study aims to investigate the characteristics, as well as the purpose and posts of the COVID-19 Facebook groups. Design/methodology/approach A systematic search for COVID-19 Facebook groups was conducted on June 1, 2020. Characteristics of the groups were examined using descriptive statistics. Mann-Whitney test was used to study the differences between groups. The study of the most popular groups’ posts was also carried out using the content analysis method. Findings The groups had a combined membership of 2,729,061 users. A total of 147,885 posts were received. There were about approximately 60% public groups. A high percentage of the groups (86.5%) had descriptions. The results showed a significant relationship between the groups’ description status and the number of members (p-value = 0.016). The majority of COVID-19 Facebook groups (56%) were created to meet their members’ information needs. The highest number of studied posts were related to vaccination (35.2%), followed by curfew rules (19.6%) and symptoms (10.6%). Originality/value Translating these insights into policies and practices will put policymakers and health-care providers in a stronger position to make better use of Facebook groups to support and enhance public knowledge about COVID-19.

PurposeThis paper aims to discuss the public knowledge project (PKP) preservation network (PN), which provides free preservation services for eligible journals by collecting article content and preserving it in a network of (at the time of writing) eight “preservation nodes” using the LOCKSS system. The PKP PN was launched in June 2016. Design/methodology/approachThis paper addresses the development and implementation of a free, distributed digital PN for open journal systems (OJS) content. It discusses challenges in developing the network, in particular relating to preserving content from a set of partners who have no formal business relationship with PKP. The paper examines data regarding journals that have opted in to the network to date and considers interface usability and other barriers facing those that have not joined. FindingsWithin 18 months of launch, more than 600 journals had opted to be preserved in the PKP PN. Many more journals are eligible to join the network; the paper explores potential strategies to increase participation and identifies and proposes methods to overcome technical and communication barriers. Originality/valueThis paper describes a highly collaborative, open-source preservation initiative which forms a unique part of the e-journal preservation landscape and preserves a particularly vulnerable portion of the scholarly record.

Purpose – This paper aims to examine Patrick Wilson’s 1977 essay, Public Knowledge, Private Ignorance, which emphasizes practice rooted in theory. Modern reference work ought to look back to this 35-year-old essay to be reminded of the intent of reference practice by considering Wilson’s discussion. Design/methodology/approach – This paper examines Wilson’s decades-old thesis and applies it to reference work and reference resources for today’s information professionals. Findings – The crux of Wilson’s essay remains relevant today when applied to reference work and information-seeking. Originality/value – This essay leaves readers with practical tips for reference work rooted in theory, and also expands on Wilson’s 1977 essay from a contemporary viewpoint, providing guidance for modern reference librarianship.


Significance In October, Netanyahu travelled to Oman -- the first visit there by an Israeli premier in decades. In the past few years, relations between Israel and most of the six Gulf Cooperation Council (GCC) member states have warmed, but this has not been publicised. More recently, GCC states have become less concerned whether their relations with Israel become public knowledge. Meanwhile, the United States is encouraging rapprochement as one of the anchors of its Middle East policy. Impacts Netanyahu may soon visit Bahrain, the first public visit by an Israeli leader to the country. Relations with Qatar will follow a separate track to other Gulf states. A political opening would create economic opportunities.


Subject The 'golden visa' controversy in the EU. Significance The European Commission's announcement on October 10 that it would investigate so-called 'golden visa' schemes follows a report by Global Witness and Transparency International warning that insufficient applicant background checks exposed the EU to large-scale money laundering and corruption. Impacts Greater public knowledge of golden visas will increase domestic pressure on governments. Scandals could worsen relations between the EU and non-EU countries. Applications for visas in the United Kingdom will likely decline if there is a Brexit deal.

Purpose – Despite legislation in place, there is still a gap in knowledge and awareness of the communities on the issues of e-waste handling and management. It is important to understand the knowledge and awareness levels of the consumers of electronic products who ultimately become the generators of e-waste in a community. The current study is based on a survey conducted in an urban setting to understand people's perception about the genesis of issues related to e-waste and its management. The purpose of this paper is to study the findings that could help in designing customized awareness programmes for addressing this concern more effectively. Design/methodology/approach – A survey was conducted in Delhi to understand public knowledge and awareness related to e-waste management in the city and country. A limited random survey was conducted with a sample size of 400 individuals in Delhi from middle class belonging to different educational backgrounds and professions. Personal interview method was used to collect in-depth information related to the issues of e-waste and its management. A questionnaire was developed and pilot tested before actual start of the survey. The questionnaire consisted of two sections – first about baseline information related to their age, family size, family income and educational background and second on their knowledge and awareness regarding e-waste and its management. Also, the practices they followed regarding e-waste at their household level were enquired. The questionnaire consisted of both open-ended and close-ended questions. Most of the questions had multiple-choice options, which made it easy for the respondents to answer them appropriately. The open-ended question gave the respondents ample time and space to express their views. The open-ended questions besides strengthening the close-ended questions provided a lot of qualitative information and made the study interesting. Apart from just interviewing, informal interactions were also used as a tool for data collection. During the course of the study, informal interactions were done with respondents to familiarize them with the objectives of the present study, their role and benefits to them from the study. Findings – The present study aimed to gauge the awareness levels and practices of people regarding e-waste management. The survey conducted in Delhi revealed that significant fraction of middle-class population is still unaware of the issue; however, on getting the information they were able to link the impacts of improper management of e-waste with detrimental health outcomes. For those who knew about it, the main sources of information to them were found to be internet, and print media. However, despite some awareness about the issue, most respondents were totally unaware about correct ways of its recycling and management. An important finding of the study was that 12-26 per cent people replace their major electronic goods like refrigerators, food processors, personal computers and music systems within the first three years of purchase. Discarding products within their periods of useful lives leads to enhanced generation of e-wastes. Along with e-waste generation, this also puts additional stress over the resources used for manufacturing of these products. On management of e-waste, most of the respondents opined of need of having efficient recycling units and effective mass awareness programmes. The survey also revealed the willingness of users to pay extra cost for proper management of e-waste provided that there is proper cost sharing between consumers and producers. This also raises an important aspect of extended producer responsibility (EPR). EPR puts additional responsibility and onus on the manufacturer of the product to not only produce durable quality of products but also take back the obsolete products and manage the e-waste. This also means that the manufacturers will have to use recyclable material in manufacturing of new products for economic management of e-waste at the later stage. Although, in Indian context it would be a challenge to implement the concept of EPR, especially with the active informal sector. The respondents quite adequately put equal responsibilities on the government, consumers and producers for effective e-waste management. The study clearly highlights the issues perceived by the middle-class population of Delhi and can be replicated in other major cities for re-authentication of the facts. The study could prove to be important in designing awareness programme related to the issue. Originality/value – This paper presents the results of a questionnaire survey-based study that was employed to understand the perception of a sample of respondents. Analysis of the data reveals that the knowledge on the issue of e-waste is minimal and requires massive awareness drives for senitization.

PurposeThe purpose of this paper is to propose an attitude control algorithm for spacecraft with geometric constraints.Design/methodology/approachThe geometric constraint is reformulated as a quadratic form when quaternion is used as attitude parameter, then the constraint is proved to be nonconvex and is further transformed to a convex one. By designing a new constraint formulation to satisfy the real constraint in the predictive horizon, the attitude control problem is reshaped to a convex planning problem which is based on receding horizon control.FindingsThe proposed algorithm is more effective in handling geometric constraints than previous research which used single step planning control.Practical implicationsWith novel improvements to current methods for steering spacecraft from one attitude to another with geometric constraints, great attitude maneuver path can be achieved to protect instruments and meanwhile satisfy mission requirements.Originality/valueThe attitude control algorithm in this paper is designed especially for the satisfaction of geometric constraints in the process of attitude maneuver of spacecraft. By the application of this algorithm, the security of certain optical instruments, which is critical in an autonomous system, can be further assured.

PurposePublic participation is essential for mitigating local resistance faced by the environmentally stigmatized facilities. The purpose of this study is to investigate public participation intention in the decision-making of waste incineration power (WIP) projects by examining the role of perceived corporate social responsibility (PCSR) and public knowledge (PK) based on the theory of planned behavior (TPB).Design/methodology/approachA theoretical model correlating PCSR with public participation intention was developed by using the constructs of TPB as the mediators and PK as the moderator. Drawing on structural equation modeling (SEM), the data collected from 485 local residents of the WIP projects in Jiangsu, China were analyzed to test the model.FindingsCompanies' CSR practice went through public attitude, subjective norm and personal norm as mediating steps towards promoting participation intention. PK positively moderated the indirect relationships between PCSR and participation intention. Moreover, attitude, subjective norm and personal norm were found to have a positive effect on participation intention.Originality/valueThis study advances the understanding of public participation intention and enriches the literature relating to CSR and TPB involved in infrastructure development. In order to improve public participation intention, companies should take strategic social responsibility actions and present the benefits and moral values of the activities to the public, and as well make effort to diffuse WIP-related knowledge through interactive activities with the public. Authorities should establish social and personal value systems that praise public participation and improve their expectations of participation outcomes.
