Multilayer weighted social network model
Recent empirical studies using large-scale data sets have validated the
Granovetter hypothesis on the structure of the society in that there are
strongly wired communities connected by weak ties. However, as interaction
between individuals takes place in diverse contexts, these communities turn out
to be overlapping. This implies that the society has a multilayered structure,
where the layers represent the different contexts. To model this structure we
begin with a single-layer weighted social network (WSN) model showing the
Granovetterian structure. We find that when merging such WSN models, a
sufficient amount of interlayer correlation is needed to maintain the
relationship between topology and link weights, while these correlations
destroy the enhancement in the community overlap due to multiple layers. To
resolve this, we devise a geographic multilayer WSN model, where the indirect
interlayer correlations due to the geographic constraints of individuals
enhance the overlaps between the communities and, at the same time, the
Granovetterian structure is preserved.Comment: 9 pages, 9 figure
Model Checking Social Network Models
A social network service is a platform to build social relations among people
sharing similar interests and activities. The underlying structure of a social
networks service is the social graph, where nodes represent users and the arcs
represent the users' social links and other kind of connections. One important
concern in social networks is privacy: what others are (not) allowed to know
about us. The "logic of knowledge" (epistemic logic) is thus a good formalism
to define, and reason about, privacy policies. In this paper we consider the
problem of verifying knowledge properties over social network models (SNMs),
that is social graphs enriched with knowledge bases containing the information
that the users know. More concretely, our contributions are: i) We prove that
the model checking problem for epistemic properties over SNMs is decidable; ii)
We prove that a number of properties of knowledge that are sound w.r.t. Kripke
models are also sound w.r.t. SNMs; iii) We give a satisfaction-preserving
encoding of SNMs into canonical Kripke models, and we also characterise which
Kripke models may be translated into SNMs; iv) We show that, for SNMs, the
model checking problem is cheaper than the one based on standard Kripke models.
Finally, we have developed a proof-of-concept implementation of the
model-checking algorithm for SNMs.Comment: In Proceedings GandALF 2017, arXiv:1709.0176
Ecological Social Development Model of Health Behavior of Conduct Achievement MDGs 5
Behavior of pregnant women who support the achievement of MDG 5 has not been fully achieved, one antenatal visit, shows there are still pregnant women who do not perform pregnancy tests regularly. The research aims to develop a model with Social Ecological Approach Model of Health Behavior in order to achieve the Millennium Development Goals by objective 5 with indicator of antenatal visits as well as aid delivery plan both place of birth and birth attendant. Observational study design, analytic, cross-sectional sample of 100 pregnant women who visit antenatal care at the health center Krembangan South Surabaya, simple random sampling, instruments using questionnaires, data analysis descriptive and inferential, using structural equation modeling (Structural Equation Modelling). The development of the social model of ecological models of health behavior to the behavior of the achievement of MDG 5 by the dominant factor is the construction of models intrapersonal factors include knowledge, attitude and self-efficacy, interpersonal factors include the support of family and community factors include health result support model testing goodness of fit note that the resulting model is an appropriate model used in the interpretation of the model because it has a model fit the criteria of empirical data generated by the study. The model can be used to strategize interventions in antenatal care is increasing knowledge, forming attitudes and self-efficacy through various activities such as prenatal classes or groups in pregnancy exercise as well as the involvement of family and health volunteers in assisting pregnant women to childbed
The European Social Model
The European Social Model is a fundamental part of what Europe stands for, but a very important issue to know is that this model is not only European, not wholly social and not a model. The European Social Model is not limited to social policy in the narrow sense: welfare, healthcare, pensions, but it includes also employment policy such as labour market rules, equality policies, benefit rules. The European Social Model is only possible because Europeans accept the importance of the state.European social model, social policy, employment policy, institutional paths
A spatial model for social networks
We study spatial embeddings of random graphs in which nodes are randomly
distributed in geographical space. We let the edge probability between any two
nodes to be dependent on the spatial distance between them and demonstrate that
this model captures many generic properties of social networks, including the
``small-world'' properties, skewed degree distribution, and most distinctively
the existence of community structures.Comment: To be published in Physica A (2005
A social purpose model for nursing
The very current international debate regarding the construction of professional role-identity in nursing involves analysis of context, competency, reflection, and theory; what most of the literature shows is that nursing continues to struggle with inherited moral and behaviourist constructs in which essential is in opposition to essentialist caring values and remains part of a convoluted argument (Goodrick & Reay, 2010). Each of these two types of caring either figure or pre-figure in the âfuture of nursingâ, which, in the 21st Century is contained within the market economy of healthcare reforms and international change (Holland, 2008; Ball & Pike 2009; Ball & Regan 2010). Therefore, how nursingâs past is mapped is germane to any current or future understanding of nursing in a multi-disciplinary workforce. The paper provides a historical mapping of the concept of new nursing from when it was utilised in another context nearly eighteen years ago to now in the United Kingdom (UK). The paper includes a critical discussion of nursingâs purposeful future to make the discussion more meaningful from an international perspective. Cartographically linking the past to the present is important, but if there is opportunity to define and identify the profession for a purposeful future, appropriate tools are needed to do so. Therefore, the paper offers a social purpose model in which a Subjective, Objective, and Contextual Ideal of what nursing is today can be explored critically and applied both to the student and mentorâs practice arena
Hypergraph model of social tagging networks
The past few years have witnessed the great success of a new family of
paradigms, so-called folksonomy, which allows users to freely associate tags to
resources and efficiently manage them. In order to uncover the underlying
structures and user behaviors in folksonomy, in this paper, we propose an
evolutionary hypergrah model to explain the emerging statistical properties.
The present model introduces a novel mechanism that one can not only assign
tags to resources, but also retrieve resources via collaborative tags. We then
compare the model with a real-world dataset: \emph{Del.icio.us}. Indeed, the
present model shows considerable agreement with the empirical data in following
aspects: power-law hyperdegree distributions, negtive correlation between
clustering coefficients and hyperdegrees, and small average distances.
Furthermore, the model indicates that most tagging behaviors are motivated by
labeling tags to resources, and tags play a significant role in effectively
retrieving interesting resources and making acquaintance with congenial
friends. The proposed model may shed some light on the in-depth understanding
of the structure and function of folksonomy.Comment: 7 pages,7 figures, 32 reference
One-, Two-dimensional Model of Personal Identity and Personal Being, as an Accumulator of âZombiesâ Ontology (Regressive Tendency of Combining a Living Body and a Corpse Within a Semantic Field of the âBodyâ Concept in 19 European Languages and in All Hie
The aim of research is revealing the correlation of one-, two-dimensional models of personal identity and the ontology of a dead body without signs of consciousness (âzombiesâ). Research methods are hermeneutic and systemic structural. The author pays special attention to the phenomena of âphilosophical, social, soulless zombiesâ. It is specified that such concepts as anima (Latin), fren (Greek), ç”é (Chinese), çČŸç„ (Chinese), à€à€€à„à€źà€š (atman) (Sanskrit), à€Źà„à€Šà„à€§à€ż (Buddhi) (Sanskrit), ۱ÙÙŰÙ (ruh) (Arabic), ŚŚ Ś©ŚŚ (Hebrew); ŚšŚŚ (Hebrew), ÏÏÏ'Îź (psyche) (Greek), spirit (English), espritâ (French), gemĂŒt (German), geist (German), Körper (German),body (English),corpus (Latin), Le corps (French), chair (French) contribute most to the deformation of personal identity. Both the transcendental form of identity (spirit, soul) and material (human body) are subject to deformation. Using the example of the substitution of the âgod of the morningâ (Lucifer) for the âdevilâ (Satan) within the Latin language, the practice of influencing the collective consciousness of people of the transformational power of letters-symbols relating to the structure of the alphabetical plan of two-dimensional dimension (as understood by A. Sviridov). It is revealed that the concepts of transformation of personal identity within 19 European languages and all hieroglyphic languages are created today by critical masses of people whose consciousness is congruent with the phenomenon of "social zombie"
Elaboration of the Model of Formation of Readiness of Future Primary School Teachers to the Use of Learning-playing Technologies
The study characterizes the structural-functional model of formation of readiness of students of the specialty âPrimary educationâ to using learning-playing technologies in the educational process. Among general modeling forms there was chosen the combined model (graphic descriptive scheme) of the structural-functional type. There was substantiated the main idea of modeling of the process of formation of future primary school teachers' readiness to using learning-playing technologies, especially, elaboration of such structural-functional model that would allow to improve the effectiveness of this process, to make it correspondent to social requirements and expectations from realization of New Ukrainian school principles. It was determined, that the object of modeling is the process of formation of readiness to using learning-playing technologies, realized within the general system of the professional training of future primary school teachers. The aim of the model creation was formulated: elaboration of the schematic construction that embodies the abstract structure and the real projected process and result. The theoretical-methodological approaches to the model projecting process were separated, namely: system, activity, personally oriented, competence. The main blocs of the elaborated structural-functional model were separated, especially, target, content, procedural and resulting
