    This article aims to offer a comprehensive overview of the existing literature on the hackathon phenomenon to offer scholars a common ground for future research and managers and practitioners research-based guidelines on best planning and running a hackathon. A review of the most relevant literature on hackathons was conducted to serve as the research basis for our integrative model and guidelines. This article synthesizes the research on hackathons to offer comprehensible guidelines for practitioners while also providing questions for future hackathon researchers. We differentiate between the different design characteristics of hackathons while noting their advantages and disadvantag...

    In this paper we address the question if, for points P,Q∈P2, I(P)m⋆I(Q)n=I(P⋆Q)m+n−1 and we obtain different results according to the number of zero coordinates in P and Q. Successively, we use our results to define the so called Hadamard fat grids, which are the result of the Hadamard product of two sets of collinear points with given multiplicities. The most important invariants of Hadamard fat grids, as minimal resolution, Waldschmidt constant and resurgence, are then computed.

    Online social network datasets contain a large amount of various information about their users. Preserving users’ privacy while publishing or sharing datasets with third parties has become a challenging problem. The k-automorphism is the anonymization method that protects the social network dataset against any passive structural attack. It provides a higher level of protection than other k-anonymity methods, including k-degree or k-neighborhood techniques. In this paper, we propose a hybrid algorithm that effectively modifies the social network to the k-automorphism one.

    Resilience is a topic that is currently receiving increased attention. In general, resilience refers to the capacity of those who, even under the most stressful circumstances, are able to cope, to rebound, and to go on and thrive. Resilient families are able to regain their balance following crises that arise as a function of either nature or nurture, and to continue to encourage and support their members as they deal with the necessary requirements for accommodation, adaptation and, ultimately, healthy survival. Handbook of Family Resilience provides a broad body of knowledge regarding the traits and patterns found to characterize resilient individuals and well-functioning families, ...

    Modern jurisprudence has typically been presented as a debate between legal positivism and natural law. Though the demise of legal positivism has been touted despite its pre-eminence in past decades, it is clear that there remains a vigorous debate surrounding this theory. It is noteworthy that Hans J. Morgenthau’s legal thought and critique of legal positivism have remained unexplored in the context of this debate. Largely forgotten, his legal thought answers questions that lie at the heart of the natural law and legal positivist debate. It showcases his deeply nuanced understanding of legal and political theory and contains a powerful and insightful commentary on the fundamental pro...

    User alignment across online social network platforms (OSNPs) is a growing concern with the rapid development of internet technology. In reality, users tend to register different accounts on multiple OSNPs, and the network platforms are reluctant to share network structure and user’s information due to business interest and privacy protection, which brings great obstacles to cross-platform user alignment. In view of this, we propose a homomorphic encryption-based social network alignment (HE-SNA) algorithm from the perspective of privacy leakage. Specifically, we first consider the OSNPs as a system containing multiple social networks, that each participant of OSNPs owns part of the n...

    During the transition from paediatric to adult healthcare there is a gap between asthma guidelines and actual management with decreased healthcare consultations and dispensations of asthma medications after the transition to adult healthcare among young people with asthma. How health-related quality of life (HRQoL) develops during the transition from adolescence to young adulthood is unclear. Our aim was therefore to investigate HRQoL among young people with asthma during the transition to adulthood. Further, to assess if level of asthma control and physical activity influence any potential association between asthma and HRQoL.

    Hearing loss is one of the most prevalent chronic health problems worldwide and a common intervention is the wearing of hearing aids. However, the tedious fitting procedures and limited hearing experts pose restrictions for the popularity of hearing aids. This paper introduced a hearing loss classification method based on the insertion gain of hearing aids, which aims to simplify the fitting procedure and achieve a fitting-free effect of the hearing aid, in line with current research trends in key algorithms for fitting-free hearing aids. The proposed method innovatively combines the insertion gain of hearing aids with the covariates of patient’s gender, age, wearing history to form a...

    Heart rate variability (HRV) is a valuable indicator of autonomic nervous system integrity and can be a prognostic tool of COVID-19 induced myocardial affection. This study aimed to compare HRV indices between patients who developed myocardial injury and those without myocardial injury in COVID-19 patients who were admitted to intensive care unit (ICU).

    Remote sensing of vital signals, including respiration and heartbeat signals, is an essential application of ultra-wideband impulse (UWB) radar. UWB radar measures the vital signal by a small motion of the thorax in the breathing and cardiac activities. The motion caused by cardiac activity is small compared to the motion of respiration and challenging to be detected in a real-life application. In this paper, we propose an algorithm for the enhancement of the signal-to-noise ratio (SNR) of the heartbeat signal. The proposed algorithm analyzes the correlation of the multichannel vital signals for taking the common harmonic component corresponding to the heartbeat signal. Thus, the algo...

    Ambulance data has been reported to be a sensitive indicator of health service use during hot days, but there is no comprehensive summary of the quantitative association between heat and ambulance dispatches. We conducted a systematic review and meta-analysis to retrieve and synthesise evidence published up to 31 August 2022 about the association between heat, prolonged heat (i.e. heatwaves), and the risk of ambulance dispatches. We initially identified 3628 peer-reviewed papers and included 48 papers which satisfied the inclusion criteria. The meta-analyses showed that, for each 5 °C increase in mean temperature, the risk of ambulance dispatches for all causes and for cardiovascular ...

    The main question of the present study is how much are the former post-mining mounds (PMM) - the ancient remnants of mining of a provisional nature located in forest areas-contaminated by heavy metals (HM). To investigate if the PMM contain HM, we collected 15 soil samples from PMM and, for comparison, 15 from the surroundings - all these samples (30) were collected from a depth of 5–30 cm by soil auger. To find how deep the contamination of HM goes, we did 4 soil profiles to the depth 100 cm in four randomly selected PMM. In every soil profile, 4 soil samples were collected (16 soil profile samples). In total, 46 soil samples were analysed. Concentrations of HM were measured using sp...
