An effective analysis of the battlefield situation and spatio-temporal data model in a sea battlefield has great significance for the commander to perceive the battlefield situation and to make the right decisions. Based on the existing spatio-temporal data model, the present paper gives a comprehensive analysis of the characteristics of sea battlefield data, and chooses the object-oriented spatio-temporal data model to modify it; at the same time this paper introduces sea battlefield space-time algebra system to define various data types formally, which lays the foundation for the establishment of the sea battlefield spatio-temporal data model.

Abstract Study question Is age a key criteria for characterizing the experience of families in telling donor offspring about the facts of their conception? Summary answer The study shows that, although donor offspring’s age at the time of disclosure has an impact, it is insufficient to describe these families’ experiences What is known already Secrecy was the norm for decades in donor conception, but “openness” has now become the new core value for institutions, professionals and interest groups. Accordingly, in recent years information-sharing practices have shifted in donor conceived families, but a proportion of parents, especially heterosexual couples, still appear to not inform their children about their being donor conceived. Disclosure recommendations seem difficult to apply in practice. A recurring question is: when should children be told? Age is presented as a key criteria: the younger the children are when their conception story is shared, the less of a problem it would create. Study design, size, duration The qualitative social science study includes two sets of semi-directive interviews conducted with 20 French sperm donor conceived adults (April-Dec. 2019) and 22 French parents by sperm, egg or double donation (Feb.-Oct. 2020). Calls for interviews aimed at donor conceived adults and parents by donation were shared on the Internet, in the media (press, radio, television) and through interest groups (PMAnonyme, BAMP!, MAIA) in France. The contact initiative was left to potential participants. Participants/materials, setting, methods Donor conceived participants include 17 women and 3 men conceived 1960–2000 through anonymous sperm donation in heteroparental families. The parent participants include 20 families (20 mothers, 2 fathers) who used donor conception—mainly anonymous (19)—in France, Spain and the Czech Republic starting in the 1980s. 17 conceived as heteroparental couples, 2 as solo-mothers-by-choice and 1 as a same-sex couple. 17 have already informed their offspring of the facts of their conception. Main results and the role of chance The participants’ experiences of disclosure appear to be bound to their historical and social context, especially regarding the prevailing norms on secrecy. Older parents mention having been advised by clinic professionals to keep the facts of their conception from their child(ren). Some also feared the stigma related to infertility. In contrast, some younger donor conceived participants recall the use of a children’s book while being told of their conception as toddlers. Beyond age, the larger context thus affects information-sharing practices. Furthermore, experiences of disclosure are impacted by the family context and history. Some are embedded within larger events such as divorces or the death of a family member. The story of the donation may be linked to narratives of diseases (such as cancer) or traumatic events (such as the loss of a fetus in utero) that may prevail over donor conception or make it untellable. Age proves to be an insufficient criteria to qualify these experiences, all the more so since “disclosure” sometimes unfolds in several steps. Some parents have first talked about their fertility issues without mentioning the use of a donor. Behind the prevailing norm of “openness”, difficulties in actually disclosing are confirmed. Limitations, reasons for caution Being qualitative, the study only includes a small number of participants without claiming exhaustivity nor representativity. It imperfectly reports on the view of those who do not disclose, as all participants question the principle of secrecy, many being members of interest groups defending openness. Wider implications of the findings: Our results complement existing studies that emphasize the weight of age in donor conceived families’ experience regarding disclosure. Age alone cannot describe information-sharing practices that are embedded within their historical and social context as well as the family context and history. Results thus inform familial difficulties related to disclosure. Trial registration number Not applicable

On November 26th, 2020, Deputy Assistant Commissioner Lucy D'Orsi presented Policing During COVID-19: Perspectives from MET Police, UK at the 2020 CASIS West Coast Security Conference. The presentation was followed by a panel question and answer period with other speakers. The key points of discussion focused on the challenges faced by MET Police in a saturated online environment, harvesting the right information, sharing it with the public and private sectors, and building trust.

Using materials from PwC’s data analytics case study with a fictitious company, Pixystems Toy Company, Inc. (PwC, 2017), henceforth Pixystems Toys, the authors developed a comprehensive, multi-part data analytics project applicable in a variety of accounting courses.  The project follows the common data analytics framework (ask the right questions, extract, transform and load (ETL) the data, perform appropriate analyses and present the results).  Students apply this framework to the sales and purchases cycles.  For each students develop relevant questions, build a data model and perform other ETL procedures, perform analytics and prepare a presentation to convey insights and recommendations.  For the sales cycle, Microsoft Excel is the analytics tool; for the purchases cycle, Tableau is used. This project provides an opportunity for students to gain experience with two analytics tools, understand the process of building a data model, and wrestle with how to convey the results of their analysis.

This chapter examines homeland security information systems (HSIS) with a focus on local governments. Local governments are typically the first at the scene when responding to an emergency or a terrorist attack. The most notable incidents are Hurricane Katrina and the terrorist attacks of September 11, 2001. In both of these incidents the first responders were the local governments, which faced dual issues of communication and information sharing. It is important to understand the current level of preparedness and use of HSIS in local governments. This chapter tries to discern the relative priority of HSIS compared to other priorities of local governments in the realm of homeland security. This chapter first outlines some background information on local governments with respect to their organizational structure and level of homeland security preparedness. The second section outlines the stages of e-government adoption, which is commonly discussed in the local e-government literature. Third, there is a discussion of homeland security information sharing between the federal, state, and local governments. There is some evidence presented from existing surveys of the impact of HSIS on local governments. Finally, there is survey results presented from a study conducted by the International City/ County Management Association (ICMA) on homeland security preparedness. This survey information is used to determine where HSIS fits into local priorities on homeland security.

Threat intelligence helps businesses and organisations make the right decisions in their fight against cyber threats, and strategically design their digital defences for an optimised and up-to-date security situation. Combined with advanced security analysis, threat intelligence helps reduce the time between the detection of an attack and its containment. This is achieved by continuously providing information, accompanied by data, on existing and emerging cyber threats and vulnerabilities affecting corporate networks. This paper addresses challenges that organisations are bound to face when they decide to invest in effective and interoperable cybersecurity information sharing and categorises them in a layered model. Based on this, it provides an evaluation of existing sources that share cybersecurity information. The aim of this research is to help organisations improve their cyber threat information exchange capabilities, to enhance their security posture and be more prepared against emerging threats.
