Document structure-driven investigative information retrieval

Data-driven investigations are increasingly dealing with non-moderated, non-standard and even manipulated information Whether the field in question is journalism, law enforcement, or insurance fraud it is becoming more and more difficult for investigators to verify the outcomes of various black-box systems To contribute to this need of discovery methods that can be used for verification, we introduce a methodology for document structure-driven investigative information retrieval (InvIR) InvIR is defined as a subtask of exploratory IR, where transparency and reasoning take centre stage The aim of InvIR is to facilitate the verification and discovery of facts from data and the communication of those facts to others From a technical perspective, the methodology applies recent work from structured document retrieval (SDR) concerned with formal retrieval constraints and information content-based field weighting (ICFW) Using ICFW, the paper establishes the concept of relevance structures to describe the document structure-based relevance of documents These contexts are then used to help the user navigate during their discovery process and to rank entities of interest The proposed methodology is evaluated using a prototype search system called Relevance Structure-based Entity Ranker (RSER) in order to demonstrate its the feasibility This methodology represents an interesting and important research direction in a world where transparency is becoming more vital than ever

Disrobing the emperor : mainstream CSR research and corporate hegemony

Purpose &ndash; This paper aims to utilise a typological matrix as the basis to categorise various corporate-society interventions. It aims to argue that an instrumental version of corporate social responsibility (CSR) is hegemonic in both the theoretical and normative domains of mainstream research, and that this hegemony underpins an intellectual blockage that prevents the field from achieving critical reflexivity and ultimately, a justifiable raison d\u27e^tre. Design/methodology/approach &ndash; The paper reflects on the extant CSR literature in the context of globalisation; presents a two-dimensional typological matrix to be used in positioning corporate-society interventions; provides examples of particular activities relevant to each quadrant of the matrix; and considers the wider political economy of CSR research. Findings &ndash; The logical implications of the corporation as an institution behaving in increasing accordance with the normative expectations of mainstream CSR scholarship will likely lead in the direction of increasing corporate hegemony. Practical implications &ndash; The paper proposes the adoption of the more theoretically coherent and empirically precise terms enlightened self-interest and corporate social irresponsibility in CSR and related research streams, as well as the institutional relocation of much future CSR research to disciplinary areas outside of the business school. Originality/value &ndash; The typological matrix presented in this paper offers a new way of locating corporate-society interventions. The partial abandonment of the term &ldquo;CSR&rdquo; by researchers, as well as the institutional relocations of much CSR research, are original notions.<br /

Leveraging Document Structures for Analytical and Investigative Information Retrieval

Due to data leaks, social media and the opening of various government databases, data-driven investigative methods have become available to a wider set of actors, including journalists. Retrieval, search and discovery are vital aspects of these data-driven investigations (DDIs). By contributing to these research areas, this thesis aims to develop methods that can be used in such investigations. This thesis identifies two characteristics required of retrieval and search methods intended for DDIs: Firstly, the underlying models need to be transparent. Secondly, the models should leverage document structures with and without supervised learning. The core contribution of this thesis is to develop a retrieval method that has these two characteristics and to demonstrate its value in investigative retrieval. By having these characteristics the proposed method — denoted information content field weighting (ICFW) — also contributes to the broader research area of establishing reliable standards for structured document retrieval (SDR). With respect to ensuring model transparency, the thesis formulates and evaluates formal constraints for SDR. These constraints facilitate the analytical evaluation of existing and proposed models, thus allowing us to reason about their behaviour in a more systematic and logical manner. This adds a layer of transparency to the proposed, as well as existing SDR models, that was not attainable before. In order to leverage the document structure for better performance, ICFW defines the importance given to a document field, not as a semantic property of the collection, but as a statistical property given to each document field. Analysis showing that ICFW satisfies all the proposed constraints for SDR, unlike any existing model, together with a formal evaluation of the method, demonstrates that it is indeed able to leverage document structures in new ways. Finally, the thesis demonstrates that the ICFW method can be used in an investigative retrieval scenario by developing a prototype search system which is evaluated on a hypothetical investigative search task. The system uses the concept of relevance structures to estimate the context in which entities occur in a data collection. These contexts are then used to rank other entities based on the similarity of their context. Overall, the research presented in this thesis shows that a focus on transparent analytical SDR models has significant potential in advancing investigative retrieval and the field of Information Retrieval in general

Weight transitions and psychosocial factors : A longitudinal cohort study of Finnish primary school children with overweight

For targeted prevention and treatment of childhood obesity, primary health care needs methods to identify children potentially developing obesity. The objectives of this study were to examine transitions across weight categories and their association with psychosocial family- and school-related factors, data on which were retrieved from health records. This longitudinal cohort study comprised 507 Finnish children with overweight, identified from a random sample of 2000 sixth graders in Helsinki in 2013. We applied Markov multistate models to analyze the transition rates over six primary school years between BMI SDS categories of normal weight, overweight and obesity, as assessed by Finnish BMI-for-age reference, and to examine relations between transition rates and family- and school-related factors. Among 3116 pairs of consecutive growth measurements from 225 girls and 282 boys aged 6–14, 719 transitions from weight category to another occurred. The highest 1-year probabilities were 0.76 for girls to stay in overweight and 0.80 for boys to stay in obesity. Transitions from normal weight to overweight and from obesity to overweight were more probable than vice versa. Transitions from overweight into obesity were among girls associated with older age (HR 2.63) and divorced or single parents (HR 2.29), as well as among boys with experiences of crises (HR 2.40) and being bullied (HR 1.66). Factors identifiable in school health care and associated with the probability of transition towards obesity should be considered when planning individual support and intervention programs. © 2020 The AuthorsPeer reviewe

Management Approach : The Virtuous Corporation as a Moral Agent for Sustainable Development

This chapter examines the corporation as a moral agent for sustainable development. While sustainable development in business organizations can be argued from utility-and duty-based ethical theories, it is suggested that virtue-based ethics is needed to develop a moral agency for sustainable development, as it focuses on the organizational character. In addition, it is proposed that the biosphere (the global sum of all ecosystems) is accepted as the ultimate principal for all planetary agents to avoid an anthropocentric and only inward-looking position typical for ethical theories. Thus, a business organization can work as a nexus for virtue and develop a moral agency that contributes to the well-being of the biosphere and all of its members.Peer reviewe

Self-reported reasons for on-duty sleepiness among commercial airline pilots

Experimental and epidemiological research has shown that human sleepiness is determined especially by the circadian and homeostatic processes. The present field study examined which work-related factors airline pilots perceive as causing on-duty sleepiness during short-haul and long-haul flights. In addition, the association between the perceived reasons for sleepiness and actual sleepiness levels was examined, as well as the association between reporting inadequate sleep causing sleepiness and actual sleep-wake history. The study sample consisted of 29 long-haul (LH) pilots, 28 short-haul (SH) pilots, and 29 mixed fleet pilots (flying both SH and LH flights), each of whom participated in a 2-month field measurement period, yielding a total of 765 SH and 494 LH flight duty periods (FDPs) for analyses (FDP, a period between the start of a duty and the end of the last flight of that duty). The self-reports of sleepiness inducers were collected at the end of each FDP by an electronic select menu. On-duty sleepiness was rated at each flight phase by the Karolinska Sleepiness Scale (KSS). The sleep-wake data was collected by a diary and actigraph. The results showed that "FDP timing" and "inadequate sleep" were the most frequently reported reasons for on-duty sleepiness out of the seven options provided, regardless of FDP type (SH, LH). Reporting these reasons significantly increased the odds of increased on-duty sleepiness (KSS >= 7), except for reporting "inadequate sleep" during LH FDPs. Reporting "inadequate sleep" was also associated with increased odds of a reduced sleep-wake ratio (total sleep time/amount of wakefulnessPeer reviewe

Sinus Barotraumas in Commercial Aircrew

BACKGROUND: Sinus barotraumas are a common condition in aviation medicine, sometimes compromising flight safety and even permanently grounding aircrew. Considering this and the ever-increasing amount of commercial aviation, a thorough examination is required. METHODS: In this survey study, an anonymous, electronic questionnaire was distributed to commercial aircrew of the three major commercial airlines operating in Finland (N = 3799), covering 93% of the target population (i.e., all commercial aircrew operating in Finland, N = 4083). Primary outcomes were self-reported prevalence, clinical characteristics, and health and occupational effects of sinus barotraumas in flight. Secondary outcomes were adjusted odds ratios (OR) for frequency of sinus barotraumas with respect to possible risk factors. RESULTS: Response rate was 47% (N = 1789/3799), with 61% (N = 1088) of the respondents having experienced sinus barotraumas in flight. Of those affected, 59% had used medications, 18% had undergone surgical procedures, and 53% had been on sick leave due to sinus barotraumas (38% during the last year) in flight. Factors associated with sinus barotraumas were female sex [OR, 2.47; 95% confidence interval (CI) 1.35-4.50] and a high number of upper respiratory tract infections (>= 3 vs.Peer reviewe

Middle Ear Barotraumas in Commercial Aircrew

BACKGROUND: Middle ear (ME) barotraumas are the most common condition in aviation medicine, sometimes seriously compromising flight safety. Considering this and the ever-increasing amount of commercial aviation, a detailed overview is warranted. METHODS: In this survey study, an anonymous, electronic questionnaire was distributed to commercial aircrew of the three major commercial airlines operating in Finland (N = 3799), covering 93% of the target population (i.e., all commercial aircrew operating in Finland, N = 4083). Primary outcomes were self-reported prevalence, clinical characteristics, and health and occupational effects of ME barotraumas in flight. Secondary outcomes were adjusted odds ratios (OR) for frequency of ME barotraumas with respect to possible risk factors. RESULTS: Response rate was 47% (N = 1789/3799), with 85% (N 1516) having experienced ME barotraumas in flight. Of those affected, 60% had used medications, 5% had undergone surgical procedures, and 48% had been on sick leave due to ME barotraumas (40% during the last year). Factors associated with ME barotraumas included a high number of upper respiratory tract infections [>= 3 URTIs/yr vs. 0 LIRTIs/yr: OR, 9.02; 95% confidence interval (CI) 3.99-20.39] and poor subjective performance in Valsalva ("occasionally" vs."a lways" successful: OR, 7.84; 95% CI 3.97-15.51) and Toynbee ("occasionally" vs."always" successful: OR, 9.06; 95% CI 2.67-30.78) maneuvers. CONCLUSION: ME barotraumas were reported by 85% of commercial aircrew.They lead to an increased need for medications, otorhinolaryngology-related surgical procedures, and sickness absence from flight duty. Possible risk factors include a high number of URTIs and poor performance in pressure equalization maneuvers.Peer reviewe
