#1
Lea Himmer, Elias Müller, Steffen Gais, Monika Schönauer
There is robust evidence that sleep facilitates declarative memory consolidation. Integration of newly acquired memories into existing neocortical knowledge networks has been proposed to underlie this effect. Here, we test whether sleep affects memory retention for word-picture associations differently when it was learned explicitly or using a fast mapping strategy. Fast mapping is an incidental form of learning that references new information to existing knowledge and possibly allows neocortical integration already during encoding...

The article analyzes the configuration and trends in institutions of Higher Education and their relationship as components of the Health Economic-Industrial Complex (HEIC). The expansion of higher education is part of the transition from elite to mass systems, with tensions between quantitative and qualitative aspects. Such changes reflect different cultures and are related to international phenomena such as globalization, economic transformations, the development of new information and communication technologies, and the emergence of an international knowledge network...

Scholars across all disciplines have long been interested in how knowledge moves within and beyond their community of peers. In conservation and natural resource management, however, we are lagging behind. Rapid environmental changes and calls for sustainable management practices mean that we urgently need to be using the best knowledge possible in forming decisions, policies, and practices to protect biodiversity and sustainably manage vulnerable natural resources. While the conservation literature on knowledge exchange (KE) and knowledge mobilization (KMb) has grown in recent years, much of it is based on context-specific case studies...

BACKGROUND: While past research has recognized the importance of the dynamic nature of absorptive capacity, there is limited knowledge on how to generate a fair and comprehensive analytical framework. Based on interviews with 24 Chinese firms, this study develops a system-dynamics model that incorporates an important feedback loop among absorptive capacity, technological innovation, and product life cycle (PLC). RESULTS: The simulation results reveal that (1) PLC affects the dynamic process of absorptive capacity; (2) the absorptive capacity of a firm peaks in the growth stage of PLC, and (3) the market demand at different PLC stages is the main driving force in firms' technological innovations...

BACKGROUND: Prior knowledge networks (PKNs) provide a framework for the development of computational biological models, including Boolean models of regulatory networks which are the focus of this work. PKNs are created by a painstaking process of literature curation, and generally describe all relevant regulatory interactions identified using a variety of experimental conditions and systems, such as specific cell types or tissues. Certain of these regulatory interactions may not occur in all biological contexts of interest, and their presence may dramatically change the dynamical behaviour of the resulting computational model, hindering the elucidation of the underlying mechanisms and reducing the usefulness of model predictions...

Boolean networks (and more general logic models) are useful frameworks to study signal transduction across multiple pathways. Logic models can be learned from a prior knowledge network structure and multiplex phosphoproteomics data. However, most efficient and scalable training methods focus on the comparison of two time-points and assume that the system has reached an early steady state. In this paper, we generalize such a learning procedure to take into account the time series traces of phosphoproteomics data in order to discriminate Boolean networks according to their transient dynamics...

BACKGROUND: Biomedical information and knowledge, structural and non-structural, stored in different repositories can be semantically connected to form a hybrid knowledge network. How to compute relatedness between concepts and discover valuable but implicit information or knowledge from it effectively and efficiently is of paramount importance for precision medicine, and a major challenge facing the biomedical research community. RESULTS: In this study, a hybrid biomedical knowledge network is constructed by linking concepts across multiple biomedical ontologies as well as non-structural biomedical knowledge sources...

Posttraumatic stress disorder (PTSD) has been associated with eating disorders (EDs) and addictive behaviors, including the relatively new construct food addiction. However, few studies have investigated mechanisms that account for these associations, and men are underrepresented in studies of EDs and food addiction. We examined whether lifetime PTSD symptoms were associated with current food addiction and ED symptoms, and whether emotion regulation (expressive suppression and cognitive reappraisal), which has been associated with both PTSD and EDs, mediated these relations, in a sample of trauma-exposed, male (n=642) and female (n=55) veterans...

OBJECTIVE: Eating disorders are understudied in men and in sexual minority populations; however, extant evidence suggests that gay men have higher rates of disordered eating than heterosexual men. The present study examined the associations between sexual orientation, body mass index (BMI), disordered eating behaviors, and food addiction in a sample of male veterans. METHOD: Participants included 642 male veterans from the Knowledge Networks-GfK Research Panel. They were randomly selected from a larger study based on previously reported trauma exposure; 96% identified as heterosexual...

The communication processes of knowledge creation represent a particular class of human dynamics where the expertise of individuals plays a substantial role, thus offering a unique possibility to study the structure of knowledge networks from online data. Here, we use the empirical evidence from questions-and-answers in mathematics to analyse the emergence of the network of knowledge contents (or tags) as the individual experts use them in the process. After removing extra edges from the network-associated graph, we apply the methods of algebraic topology of graphs to examine the structure of higher-order combinatorial spaces in networks for four consecutive time intervals...

BACKGROUND: Intravenous thrombolytic therapy after ischaemic stroke significantly reduces mortality and morbidity. Actual thrombolysis rates are disappointingly low in many western countries. It has been suggested that higher patient volume is related to shorter door-to-needle-time (DNT) and increased thrombolysis rates. We address a twofold research question: a) What are trends in national thrombolysis rates and door-to-needle times in the Netherlands between 2005-2012? and b) Is there a relationship between stroke patient volume per hospital, thrombolysis rates and DNT? METHODS: We used data from the Stroke Knowledge Network Netherlands dataset...

On the basis of the social exclusion framework put forth by the Social Exclusion Knowledge Network (SEKN), we propose a framework that conceives social exclusion as a mechanism that limits access to rights, resources and capabilities needed for a healthy life. While it is widely accepted that drivers of social exclusion are structural, the consequences are experienced by individuals in their everyday lives. This article proposes an adaptation of the SEKN framework, illustrating additional basic elements that should be considered in the study of exclusionary mechanisms...

We sought, for the first time, to identify the extent of jello shot consumption among underage youth. We conducted a study among a national sample of 1,031 youth, aged 13 to 20, using a pre-recruited internet panel maintained by GfK Knowledge Networks to assess past 30-day consumption of jello shots. Nearly one-fifth of underage youth have consumed jello shots in the past 30 days and jello shots make up an average of nearly 20% of their overall alcohol intake. Jello shot users in our sample were approximately 1...

BACKGROUND: The optimal time to save a person who has had a sudden cardiac arrest is within the first few minutes of the incident. Early compression and early defibrillation should be performed at this time. Timeliness is the key to successful CPR; as such, Prof. He proposed the "platinum 10 min" system to study early CPR issues. This paper systematically evaluates the success rates of heartbeat restoration within the "platinum 10 min" among patients suffering from sudden cardiac arrest...

Script theory proposes an explanation for how information is stored in and retrieved from the human mind to influence individuals' interpretation of events in the world. Applied to medicine, script theory focuses on knowledge organization as the foundation of clinical reasoning during patient encounters. According to script theory, medical knowledge is bundled into networks called 'illness scripts' that allow physicians to integrate new incoming information with existing knowledge, recognize patterns and irregularities in symptom complexes, identify similarities and differences between disease states, and make predictions about how diseases are likely to unfold...
