    1. The problem is that the since both the JSX transpiler and the traceur compiler are actually parsing the full javascript AST, they would have to mutually agree on the syntax extensions you use: traceur can't parse the faux-xml syntax JSX adds, and JSX can't parse the async or await keywords, for example, or generator functions.

    1. We analyze the structural elements which comprise a standard scientific paper. Previous analysis generally has focused on one element of a paper at a time. However, the title, author list, affiliation, abstract, text, tables, graphs, charts, photographs and references all represent possible data resources for investigation. After specifying those elements, we focus successively on the history, normative tradition, and sociological analysis of a selection of those elements.
    1. Scientific knowledge constitutes a complex system that has recently been the topic of in-depth analysis. Empirical evidence reveals that little is known about the dynamic aspects of human knowledge. Precise dissection of the expansion of scientific knowledge could help us to better understand the evolutionary dynamics of science. In this paper, we analyzed the dynamic properties and growth principles of the MEDLINE bibliographic database using network analysis methodology. The basic assumption of this work is that the scientific evolution of the life sciences can be represented as a list of co-occurrences of MeSH descriptors that are linked to MEDLINE citations. The MEDLINE database was summarized as a complex system, consisting of nodes and edges, where the nodes refer to knowledge concepts and the edges symbolize corresponding relations. We performed an extensive statistical evaluation based on more than 25 million citations in the MEDLINE database, from 1966 until 2014. We based our analysis on node and community level in order to track temporal evolution in the network. The degree distribution of the network follows a stretched exponential distribution which prevents the creation of large hubs. Results showed that the appearance of new MeSH terms does not also imply new connections. The majority of new connections among nodes results from old MeSH descriptors. We suggest a wiring mechanism based on the theory of structural holes, according to which a novel scientific discovery is established when a connection is built among two or more previously disconnected parts of scientific knowledge. Overall, we extracted 142 different evolving communities. It is evident that new communities are constantly born, live for some time, and then die. We also provide a Web-based application that helps characterize and understand the content of extracted communities. This study clearly shows that the evolution of MEDLINE knowledge correlates with the network’s structural and temporal characteristics.

    1. One way to think about "core" biodiversity data is as a network of connected entities, such as taxa, taxonomic names, publications, people, species, sequences, images, and collections that form the "biodiversity knowledge graph". Many questions in biodiversity informatics can be framed as paths in this graph. This article explores this futher, and sketches a set of services and tools we would need in order to construct the graph. New information In order to build a usable biodiversity knowledge graph we should adopt JSON-LD for biodiversity data, develop reconciliation services to match entities to identifiers, and a use a mixture of document and graph databases to store and query the data. To bootstrap this project we can create wrappers around each major biodiversity data provider, and a central cache that is both a document store and a simple graph database. This power of this approach should be showcased by applications that use the central cache to tackle specific problems, such as augmenting existing data.
    1. The success of distributed and semantic-enabled systems relies on the use of up-to-date ontologies and mappings between them. However, the size, quantity and dynamics of existing ontologies demand a huge maintenance effort pushing towards the development of automatic tools supporting this laborious task. This article proposes a novel method, investigating different types of similarity measures, to identify concepts’ attributes that served to define existing mappings. The obtained experimental results reveal that our proposed method allows to identify the relevant attributes for supporting mapping maintenance, since we found correlations between ontology changes affecting the identified attributes and mapping changes.
    1. As the amount of scholarly communication increases, it is increasingly difficult for specific core scientific statements to be found, connected and curated. Additionally, the redundancy of these statements in multiple fora makes it difficult to determine attribution, quality, and provenance. To tackle these challenges, the Concept Web Alliance has promoted the notion of nanopublications (core scientific statements with associated context). In this document, we present a model of nanopublications along with a NamedGraph/RDF serialization of the model. Importantly, the serialization is defined completely using already existing community developed technologies. Finally, we discuss the importance of aggregating nano-publications and the role that the ConceptWiki plays in facilitating it.
    1. SKOS—Simple Knowledge Organization System—provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, and other similar types of controlled vocabulary. As an application of the Resource Description Framework (RDF), SKOS allows concepts to be composed and published on the World Wide Web, linked with data on the Web and integrated into other concept schemes. This document is a user guide for those who would like to represent their concept scheme using SKOS. In basic SKOS, conceptual resources (concepts) are identified with URIs, labeled with strings in one or more natural languages, documented with various types of note, semantically related to each other in informal hierarchies and association networks, and aggregated into concept schemes. In advanced SKOS, conceptual resources can be mapped across concept schemes and grouped into labeled or ordered collections. Relationships can be specified between concept labels. Finally, the SKOS vocabulary itself can be extended to suit the needs of particular communities of practice or combined with other modeling vocabularies. This document is a companion to the SKOS Reference, which provides the normative reference on SKOS.

    1. In contrast, theorems in Abstract Cryptography can be provedat a (high) level of abstraction without the instantiation ofthe lower levels. The lower levels inherit these theorems ifthey satisfy the postulated axioms of the higher level. Eachabstraction level can thus focus on specific aspects, such ascomposability or efficiency.

    1. Exchange value

      Exchange value appears as the property of a commodity that is exchangeable for other commodities. It also presupposes societies who produce commodities and exchange them. While all societies have things with use values, exchange value is relative to a specific time and place.

      Additionally, exchanging commodities must also presupposes a way to determine proportionality between different commodities, so that they can be exchanged in the first place.

      Exchange therefore requires some other measure that stands above the two commodities meant to be exchanged. If there were no ways in which iron and corn were found similar to a society, for example, then we would not exchange them and they would have no exchange value.

      Marx will contend that what each commodity must contain crystalized within it is value (formally) and that the substance of value is labor (viz. the common factor of both iron and corn is labor). Marx will call this kind of labor abstract labor.

    1. Is an Abstract Logo Good for your Business? December 2, 2019 shivkumar Logo & Branding An abstract logo is a logo that is known to be the most valiant logo that instantly grabs attention. These logos are stylized but simple and can create curiosity among its viewer. Every business wants to stand out to ensure they are perceived as the best in the market and this type of logo symbolizes just that. People have high expectations from these logos as it demands professionalism. Branding using this type of logo is different than the other logo types. In this type of logo, you have to invest highly in brand recognition. Your marketing plans should be more focused on creating a brand rather than selling. This type of logo requires a long term business plan and a big budget to make your brand recognized by the customer. In this article, we will discuss is using an abstract log for your business a good idea and the traits it offers along with how it is perceived by customers but before that let’s find out what is an Abstract Logo? What is an Abstract Logo? The Abstract logo is a logo that uses a symbol or icon to represent a brand. This symbol can be a letter or any symbol that may or may not mean something. It deliberately uses colors, shapes, and forms to create a symbol to attain its effect. One of the best examples that use an abstract logo is NIKE (Swoosh symbol). Key Traits of Abstract Logo Abstract logo can make your brand big and recognized all over the world. It is unique and has many traits that speak for it. The following are the traits that abstract logos have – Lasting Impression The goal of any business is to create a space in the mind and heart of their customers. This type of logo helps in creating this emotion and leaves a lasting mark on the customer.  Curiosity The first and simplest emotion which we discover in the human mind is curiosity. Edmund Burke This quote beautifully explains the basic human nature. Human beings are curious which resulted in the discovery of many advanced technologies. When someone becomes curious, then person persuades and research about that topic. The same effect can be introduced into the logo by using the abstract logo.  The abstract logo creates curiosity that leads to more brand search and more brand recognition. Ultimately, an abstract logo can create a huge fan following and authority in your market. Creativity It is difficult to design a brand image using abstract design. There is no guide that can be used for creating abstract logo. The designers have to rely on his/her experience and creativity to design this type of logo but the results that you get are some of the most creative designs. Modernism The abstract logo is forever fresh and requires less to not at all change. This logo can be used again and again over the years to represent the logo as the brand image. Modern and creative logos are an approach that can induce professionalism into the picture hence, giving a fresh look forever. When to Use the Abstract Logo? Abstract logos are best for businesses that can revolutionize a market. Nike is a brand that is well known for the athleisure wear they make. The Swoosh logo used by them makes them stand out and create a presence. If your business has similar traits then you can use this logo. The marketing of this type of business can be costly but is very effective. Psychology behind the Abstract Logo Abstract logo is a unique type of logo that affects the customer psyche in a distinct way. Abstract logo influences the customer to search about the business. But, why? This happens due to Association Principles. According to this principle, a customer creates a mental connection between the shape, color and patterns to some emotions. This emotion further triggers the person to take action regarding that event and this principle is called trigger theory. If your logo evokes some connections from person’s past then the trigger principle works and the person transfers the same emotion towards the business. The emotion can be negative and positive so, it is advised not to use any negative imagery in your logo. You can use these psychological principles to increase your sales and get recognized by your customers. Conclusion Many people, who start a business or redesign their logo, easily overlook the type of logo to use. Good logo design services are good at understanding the needs of that business. Many people design the logo without considering the goal and future projection of the business. This is a huge mistake that businesses make. The best way to get a logo designed is by taking a professional’s help and taking consultation from them.

    1. Neonatal Hypopituitarism: Approaches to Diagnosis and Treatment

      Hypopituitarism is defined as a decreased release of hypophyseal hormones, which may be caused by disease of the pituitary gland disease or hypothalamus.

      The clinical findings of neonatal hypopituitarism depend on the causes and on presence and extent of hormonal deficiency. Patients may be asymptomatic or may demonstrate non-specific symptoms, but may still be at risk for development of pituitary hormone deficiency over time. Patient history, physical examination, endocrinological, radiological and genetic evaluations are all important for early diagnosis and treatment. Links: Neonatal Hypopituitarism

    1. Abstract

      Abstract typically follows the cover page with the title, author name(s), contact information, and other relevant information. Abstract is a sales pitch. It is a short summary (200 words or so) of the entire paper that follows. It is supposed to contain the following information -- a research question(s), a theoretical argument, a research design, findings, and a conclusion.

      Does this abstract contain all the essential information listed above? Is this, thus, a good abstract or not?

    1. As with neoliberalism more generally, New Public Management is invisible, part of a new “common sense” that has somehow become hegemonic, whereby the “entrepreneurial spirit” has infused the public sector, leading to “businesslike government”. As with the claims of neoliberalism more generally as to its positive outputs in terms of prosperity, NPM has never been shown to have been successful even in its own terms. NPM “introduced punishments and rewards to produce better services with lesser staff. Instead of having freed energies and creativity of employees formerly shackled by their bureaucratic turfs, NPM reforms have bound energies into theatrical audit performances at the cost of work and killed creativity in centralizing resources and hollowing out professional autonomy... Fundamental deprivation of the legitimacy of public employees . . .has traumatized many most-committed employees and driven others toward a Soviet-type double standard.” (Juha Siltala, New Public Management : The evidence-based worst practice?, Administration; Vol. 45, No. 4.; 2013 pp. 468-493) Sekera quotes Christopher Pollitt et al., who “after compiling a database of 518 studies of NPM in Europe, determined that “more than 90% of what are seen by experts as the most significant and relevant studies contain no data at all on outcomes” and that of the 10% that had outcomes information, only 44% of those, or 4% of the total, found any improvements in terms of outcomes.” But in the end, the point of NPM is less that of measureable outcomes, and more that of the ideological victory of turning the public and its good into customers exercising their “choices” (see tax revolt example in Duggan), along of course with the radical disempowering of public administration workers and their unions, instituting “cost savings” by cutting their real income and putting more and more of the public sector’s production directly into the profit-making market.

    1. if you replace the idea that life is a narrative with the idea that life is a vision

      It's an interesting thought to replace the idea of life as a narrative vs a vision, it kind of goes along with the idea of technology being concrete of fluid. A narrative is something more concrete and a vision seems for fluid because a narrative is bound by the progression of time and in a vision things can happen simultaneously.

    1. Two patients complaining of insomnia had sleep-related periodic leg movements (nocturnal myoclonus) on polysomnographic evaluation. Both also complained of cold feet and had abnormal peripheral pulse examinations. Treatment with phenoxybenzamine, alpha-adrenergic blocker, normalized the peripheral pulse responses, reduced the complaint of insomnia, and reduced the sleep related leg movements but resulted in only mild sleep improvements. Peripheral pulse examinations of ten other patients with sleep-related periodic leg movements revealed abnormal responses in four. From these and other results, it is hypothesized that the sympathetic nervous system may mediate the periodicity of sleep related periodic leg movements.

    1. There are two related issues that we have seen when it comes to mis‐understandings about the roles of data scientists. In one case, excessivehype leads people to expect miracles, and miracle-workers. In the oth‐er case, a lack of awareness about the variety of data scientists leadsorganizations to waste effort when trying to find talent. These casestudies are based on collective experiences from many of our friends,colleagues, and Meetup members.
