    Full Text Available Social media are a phenomenon that came about with the Web 2.0. The essential characteristic of social media is the so-called user-generated content, which means that individuals and their lives are entangled in a social interaction in which their identity is to some extent subsumed under the logic of the production of profit. From the standpoint of the critique of political economy, the phenomenon of digital labor can be tackled with a digital labor theory of value. On the other hand, a question of a subjective aspect remains open. The initial hypothesis is that an analysis of a dynamic character of capitalism is necessarily connected with historical transformations of subjectivity. I will inspect which type of subjectivity is produced during the “process of production” on Facebook, how relations of the exchange of information and meaning take place inside this medium, and what kind of consciousness comes with this virtual identity. I will attempt to address this question with an explication of social forms of sharing amongst individuals on this social network. I will focus on how photos, notifications and comments structure web subjectivity and its function. Answers to such questions can help us in understanding a certain aspect of a socioeconomic structure of contemporary capitalism and bear an emancipatory potential in a possibility of negation of such social relations. The article will limit itself to the exploration of subjectivity in social media, which will be dealt with in a dynamic sense and in regard to formal conditions of communication inside social media, and in respect to a social situation in which they are.

    Full Text Available AIM: To measure the foveal avascular zone(FAZarea and to investigate the characteristics of the FAZ area in normal eyes, using optical coherence tomography(OCTangiography.METHODS: This was a cross-sectional study. The FAZ area was measured in 69 participants, for a total of 138 eyes, using RTVue-100 OCT. The relations between the FAZ area and the potential factors were evaluated by univariate and multivariate linear regression analysis. Differences between the right and left eyes were calculated, and values were compared by means of a paired t test. Pearson correlation analysis was performed to assess the relationships of the FAZ area between the right and left eyes. RESULTS: The mean FAZ area was 0.30±0.11mm2 in all subjects. For the male subjects, the mean FAZ area was 0.29±0.13mm2, and for the female subjects 0.31±0.09mm2, with no significant difference(t=-1.346,P=0.180. The FAZ area did not correlate with all the potential factors. The mean FAZ area in the right eye was 0.30±0.11mm2, and in the left eye was 0.30±0.10mm2,with no significant difference(P=0.943. There was a strong correlation between the right and left eyes for the FAZ area. CONCLUSION: OCT angiography is a noninvasive method of visualizing and measuring the FAZ area in normal subjects. The FAZ area does not correlate with old age, sex and other factors. It shows significant interocular symmetry in normal subjects.

    Full Text Available This paper focuses on the collapse of granular materials subjected to wetting action. For soils, the collapse potential depends on several parameters such as liquid limit, matric suction, compactness, initial water content and the amount of fine particles. The effect of grain size, which plays a key role in the rearrangement of grains, remains little studied and poorly understood. To investigate the capillary origin of the collapse phenomenon, we present an experimental study on macroscopic and local scales. Our results show the effect of grain size and water content on collapse.

    Full Text Available Any random sampling of a Facebook timeline or Twitter feed, to take the obvious examples, provides a prepackaged view of global politics. It is restrictive because we choose it to reflect our own pet subjects, groups, likes, and world interests. The lens is prejudiced to reflect our race, class, gender, sexuality, ideology, and affective positionality. We enter a social media world as many as 10 or 50 times a day that has ourselves as the center of the universe. This communication world is similar to an infant’s world: Someone else decides what we can see, what we can consume, what is that extra treat we can earn, if we are good: in social media terms, if we pay for it by reputational capital, or simply, if we spend enough money.

  10. Measurement of Interfacial Area Production and Permeability within Porous Media

    Energy Technology Data Exchange (ETDEWEB)

    Crandall, Dustin; Ahmadi, Goodarz; Smith, Duane H.

    2010-01-01

    An understanding of the pore-level interactions that affect multi-phase flow in porous media is important in many subsurface engineering applications, including enhanced oil recovery, remediation of dense non-aqueous liquid contaminated sites, and geologic CO2 sequestration. Standard models of two-phase flow in porous media have been shown to have several shortcomings, which might partially be overcome using a recently developed model based on thermodynamic principles that includes interfacial area as an additional parameter. A few static experimental studies have been previously performed, which allowed the determination of static parameters of the model, but no information exists concerning the interfacial area dynamic parameters. A new experimental porous flow cell that was constructed using stereolithography for two-phase gas-liquid flow studies was used in conjunction with an in-house analysis code to provide information on dynamic evolution of both fluid phases and gas-liquid interfaces. In this paper, we give a brief introduction to the new generalized model of two-phase flow model and describe how the stereolithography flow cell experimental setup was used to obtain the dynamic parameters for the interfacial area numerical model. In particular, the methods used to determine the interfacial area permeability and production terms are shown.

    2017-08-01

    The Eustachian tube (ET) is responsible for the ventilation, protection, and cleaning of the middle ear. ET dysfunction plays an important role in the pathogenesis of otitis media cases, and thus the treatment and prognosis of these cases is extremely dependent on adequate ET function, which can ultimately affect the success rate of middle ear reconstruction practices. Data research on the ET’s ventilation function is needed to ensure the success of therapy and surgery treatments in the case of Chronic Suppurative Otitis Media (CSOM) patients. This study aims to investigate ET ventilation functioning in benign type CSOM and non-otitis media subjects and to develop another modality to measure ET ventilation functioning in patients with intact and perforated tympanic membranes. A comparative cross-sectional study of 36 benign type CSOM patients and 80 non-otitis media subjects will be conducted using sonotubometry and the rated parameter measurements of ET opening frequency, amplitude and ET opening duration. Malfunctioning ventilation of the ET is more common among benign type CSOM subjects (47%) than among non-otitis media subjects (18.75%). There is a significant difference (p = 0.002) between the ET ventilation functioning of benign type CSOM subjects and non-otitis media subjects—benign type CSOM subjects have rates of malfunctioning ET ventilation that are 3.88 times higher than those of non-otitis media subjects. Patients with benign type CSOM are more likely to experience malfunctioning ET ventilation than are non-otitis media subjects.

    Full Text Available The purpose. In this article, research interest is fixed directly on the circumstances theming access personal / private as interpassivity practice of subjective life and creativity, which are mediated by modern media discourse. Methodology. Methodological base of research of contemporary experience of subjectivity is heuristic "ontological turn" in social theory, which allows to consider the subjectivity not as a reality (given, but as a procedural phenomenon, performativity, which exist in conditions of unstable ontologies, world without guarantees, indirect, thus, mass-media representations. Particular emphasis is placed on the deconstruction of traditional oppositions "objective/subjective", "public/private", "active/passive". As a result, a special interest in issues of privacy as "the place" in which the modern subject unstable ontology prefers to realize its self. Scientific novelty. It is proved that in the modern media culture, the subject is not so much a passive spectator, observer, collector information and events to represent relevant interested agents. He also actively reproduces itself in a form of "perceived privacy", which allows special mode of the experiences of private emotions "alone with everybody." Perceived privacy, although the individual reserves the right to individual control over personal space and personal statement (for example, through personal and individual electronic access to digital representations of reality, however, suggests certain techniques of "publication" themselves. It is the question of the interpassivity nature of such practices subjective life and creativity. Conclusions. Proposed research optics suggests that the person remains - the world-making being, who actively constructs their personal reality, however, when this reality is mediated by media representations, life world turns into a ready code, respectively, the active construction becomes superfluous. On the contrary, interpassivity as

    2010-01-01

    Standard models of two-phase flow in porous media have been shown to exhibit several shortcomings that might be partially overcome with a recently developed model based on thermodynamic principles (Hassanizadeh and Gray, 1990). This alternative two-phase flow model contains a set of new and non-standard parameters, including specific interfacial area. By incorporating interfacial area production, destruction, and propagation into functional relationships that describe the capillary pressure and saturation, a more physical model has been developed. Niessner and Hassanizadeh (2008) have examined this model numerically and have shown that the model captures saturation hysteresis with drainage/imbibition cycles. Several static experimental studies have been performed to examine the validity of this new thermodynamically based approach; these allow the determination of static parameters of the model. To date, no experimental studies have obtained information about the dynamic parameters required for the model. A new experimental porous flow cell has been constructed using stereolithography to study two-phase flow phenomena (Crandall et al. 2008). A novel image analysis tool was developed for an examination of the evolution of flow patterns during displacement experiments (Crandall et al. 2009). This analysis tool enables the direct quantification of interfacial area between fluids by matching known geometrical properties of the constructed flow cell with locations identified as interfaces from images of flowing fluids. Numerous images were obtained from two-phase experiments within the flow cell. The dynamic evolution of the fluid distribution and the fluid-fluid interface locations were determined by analyzing these images. In this paper, we give a brief introduction to the thermodynamically based two-phase flow model, review the properties of the stereolithography flow cell, and show how the image analysis procedure has been used to obtain dynamic parameters for the

    The aim of this project is to help lecturer conducting the class for theoretical subject easier, more understandable and more effective. This paper will give description for the lecturer through movie clip media, so it is not to dictate the lecturer, just to give an example so that in the future, lecturer can develop his/her own idea to handle this kind of subject. The research method used in this project is qualitative methods, since it will explain in detail the material used in the class, the teaching method used in the class and also the media which is used to help lecturer transform the theory from the subject itself. The key finding of this project can be conveyed briefly through these following statements. There are significant differences after using movie clip as a media, especially student‘s mastery of the material developed greatly. Movie clip encourage students to think creatively, out of the box, and avoid them to be plainly textbook. Avoid them to be bounded by words from the book, avoid them to only memorize the theory discussed in the class. But in the other way around, they can increase their knowledge by conclude it by themselves, not only by read it from the book. Next, the significance of this project, it is to stomp a beginning step to start conducting creative teaching in the class. That teaching students is not only tell them the theory, is not only make them remember the answer for the test, but teaching is also to shape their way of thinking, their creativity, their soft skill and also their learning attitude. Start from conducting a theoretical subject, then lecturer can enhance the method in this project for several other subjects. At last we as the lecturer, should consider that creativity is compulsory for our teaching, that teaching is not only work of brain but work of art and work of heart.

    Cardiovascular risk factor (RF) assessment is essential to prevent and predict cardiovascular disease. The presence of RF at early ages, are determinant for the presence of atherosclerosis later in life. To determine the RF profile of young subjects with high carotid intima media thickness (CIMT). We studied 689 subjects (50% women, mean age 36±6 years) from Santiago, Chile. We determined body mass index (BMI), waist circumference, blood pressure, fasting serum lipids, blood glucose and C-reactive protein. CIMT was assessed by ultrasound using an automatic border recognition software. Body mass index, waist circumference, blood pressure and serum lipids were significantly higher among subjects located in the higher CIMT quartile. Also, subjects in the higher quartile of CIMT had a higher prevalence of three or more RF compared with the lower quartile (p = 0.01). Finally, individuals with three or more RF showed three times more risk of being in the higher CIMT quartile, than subjects with no RF (odds ratio = 3.1, p influence of cardiovascular RF on CIMT among young subjects.

    2008-11-01

    Diagnostic accuracy and appropriate inclusion/exclusion criteria representative of children at greatest risk is of paramount importance in trials to evaluate placebo or observation as an option for acute otitis media (AOM) management. Twelve observational studies spanning the time frame 1958-2005 and 13 natural history studies spanning the time frame 1968-2006 were evaluated for the diagnostic criteria, inclusion criteria, and exclusion criteria applied within the study design. Although a bulging or full tympanic membrane (TM) with effusion is the best indication of a diagnosis of bacterial AOM based on tympanocentesis findings, few observational and natural history studies required a bulging TM. Examination of subject inclusion criteria showed that many subjects did not have AOM but rather had no middle ear disease at all or they had otitis media with effusion. Exclusion criteria of subjects were also remarkable. Frequently children bias in exclusion criteria among placebo/natural history trials in AOM. The current data favoring observation of children with AOM should be reconsidered until better studies are conducted.

    In recent years in Japan, electronic games, home computers, and the internet have assumed an important place in people's lives, even for elementary school children. Subjective health complaints have also become a problem among children. In the present study, we investigated the relationship between media use and health status in elementary school children in Japan. A cross-sectional school-based population survey was conducted in 2009 with a sample of fourth-, fifth-, and sixth-grade children (age range: 10-12 years old) in elementary schools in Japan (n = 3,464). Self-reported health, lifestyle habits, and time spent using media were assessed. The use of games, television, and personal computers was significantly associated with lifestyle (p media used for more than 1 hour was, the higher the odds ratio of the association of media use with unhealthy lifestyle and subjective health complaints was. The plural use of these media had stronger associations with unhealthy lifestyle and subjective health complaints. Game, television, and personal-computer use were mutually associated, and the plural use of these media had stronger associations with unhealthy lifestyle and subjective health complaints. Excessive use of media might be a risk for unhealthy lifestyle and subjective health complaints.

    Full Text Available Studies on youth media consumption and its effects on their being have always been the interest of many studies all over the globe. It is because of youth’s importance in the society and the roles they will play in the future, most specifically the educated ones. However, in the Philippines, there is only little information about the out of school youth. This study aims to determine the media consumption of the out of school youth since they are one of the most deprived individuals on having sufficient knowledge about media and its effects on individuals. Among other types of media, television has the highest percentage of consumption among the Filipino out of school youth more than the Internet and radio. Using statistical methods, we relate the relationship of consuming a specific media to their subjective wellbeing. Findings revealed that not all media affects the out of school youth’s feelings of being contented, joyful, and relaxed, only specific media types affects such feelings. Overall, the study shows that the out of school youth and their consumption of media are indeed related with each other.

    Full Text Available This paper posits that the concept of European identity is an important indicator of the legitimacy of the European Union (EU. It further assumes that the exposure to EU related media content can influence the feeling of European identity. In order to verify this assumption, we combined the mere-exposure-theory and the hostile media phenomenon. We assume that these theoretical concepts could help to understand the influence of media on people’s levels of attachment to the EU. Regression analyses are performed on secondary data that were collected in a Eurobarometer survey in 2013. Our findings revealed that media exposure affected the respondents’ identification with Europe, as well as the modifications of this effect based on their assessments of EU media coverage. The results of the current study not only validate assumptions about the mere-exposure effects on identity but also confirm the theoretical assumption that perceived hostility reduces such effects, whereas exposure to information that is perceived as neutral promotes the effects of media exposure on the feeling of European identity.

    A series of intermediate-scale laboratory experiments were completed in a two-dimensional flow cell to investigate gas production and migration during the application of electrical resistance heating (ERH) for the removal of dense non-aqueous phase liquids (DNAPLs). Experiments consisted of heating water in homogeneous silica sand and heating 270 mL of trichloroethene (TCE) and chloroform (CF) DNAPL pools in heterogeneous silica sands, both under flowing groundwater conditions. Spatial and temporal distributions of temperature were measured using thermocouples and observations of gas production and migration were collected using front-face image capture throughout the experiments. Post-treatment soil samples were collected and analyzed to assess DNAPL removal. Results of experiments performed in homogeneous sand subject to different groundwater flow rates showed that high groundwater velocities can limit subsurface heating rates. In the DNAPL pool experiments, temperatures increased to achieve DNAPL-water co-boiling, creating estimated gas volumes of 131 and 114 L that originated from the TCE and CF pools, respectively. Produced gas migrated vertically, entered a coarse sand lens and subsequently migrated laterally beneath an overlying capillary barrier to outside the heated treatment zone where 31-56% of the original DNAPL condensed back into a DNAPL phase. These findings demonstrate that layered heterogeneity can potentially facilitate the transport of contaminants outside the treatment zone by mobilization and condensation of gas phases during ERH applications. This underscores the need for vapor phase recovery and/or control mechanisms below the water table during application of ERH in heterogeneous porous media during the co-boiling stage, which occurs prior to reaching the boiling point of water.

    The high potential cost of storage, treatment and disposal of radioactive wastes places a premium on the longevity of installed HEPA filters in situations in radioactive processing facilities where dust capacity is a life determining factor. Previous work investigated the dust holding capacity v pressure drop characteristics of different designs of HEPA filter and also the effect of using graded density papers. This paper records an investigation of the effect of media area variation on the dust holding capacity of the {open_quotes}deep-pleat{close_quotes} design of HEPA filter. As in the previously reported work two test dusts (carbon black and sub micron sodium chloride) in the range (0.15 - 0.4{mu}m) were used. Media area adjustment was effected by varying the number of separators within the range 60 - 90. Results with the coarser dust allowed an optimum media area to be identified. Media areas greater or smaller than this optimum retained less dust than the optimum for the same terminal pressure drop. Conversely with the finer sodium chloride aerosol the dust holding capacity continued to increase up to the maximum area investigated. 7 refs., 4 figs.

    2016-02-01

    Full Text Available The advent of social media can be seen both as a risk and an opportunity by armed forces. Previous research has primarily examined whether or not the use of social media endangers or strengthens armed forces’ strategic narrative. We examine armed forces’ perceptions of risks and opportunities on a broad basis, with a particular focus on areas of deployment. The article is based on a survey of perceptions of social media amongst the armed forces of EU member states, thus adding to previous research through its comparative perspective. Whereas previous research has mainly focused on larger powers, such as the US and the UK, this article includes the views of the armed forces of 26 EU states, including several smaller nations. In analyzing the results we asked whether or not risk and opportunity perceptions were related to national ICT maturity and the existence of a social media strategy. The analysis shows that perceptions of opportunities outweigh perceptions of risks, with marketing and two-way communication as the two most prominent opportunities offered by the use of social media. Also, armed forces in countries with a moderate to high ICT maturity emphasize social media as a good way for marketing purposes.

    Dentofacial morphology may affect orofacial functions, therefore the aim of the current study was to evaluate the influence of craniofacial morphology on masticatory function, occlusal contact area (OCA), and masticatory muscles activity. Seventy-eight (78) subjects were divided into three groups according to vertical facial pattern: 1. mesofacial; 2. brachyfacial; and 3. dolichofacial. Artificial material and the sieving method were used to access masticatory efficiency (ME). OCA was determined by registration of posterior teeth. Electromyographic (EMG) activity of the masseter and anterior temporal (AT) muscles was accessed bilaterally at rest and at maximal vertical clenching (MVC). ME (%) was significantly higher in brachyfacial and lower in dolichofacial subjects. Brachyfacials presented the highest OCA (mm2) followed by meso and dolichofacial subjects. The EMG of the masseter and AT at rest and at MVC showed that dolichofacial subjects presented the lowest activity values, while brachyfacial subjects presented significantly higher measurements. Craniofacial morphology affected masticatory function, OCA, and EMG activity of the masticatory muscles.

    Brain-derived neurotrophic factor (BDNF) plays a pivotal role in the pathophysiology of suicidal behavior and BDNF levels are decreased in the brain and plasma of suicide subjects. So far, the mechanisms leading to downregulation of BDNF expression are poorly understood. To test the hypothesis that alterations of DNA methylation could be involved in the dysregulation of BDNF gene expression in the brain of suicide subjects. Three independent quantitative methylation techniques were performed on postmortem samples of brain tissue. BDNF messenger RNA levels were determined by quantitative real-time polymerase chain reaction. Academic medical center. Forty-four suicide completers and 33 nonsuicide control subjects of white ethnicity. The DNA methylation degree at BDNF promoter IV and the genome-wide DNA methylation levels in the brain's Wernicke area. Postmortem brain samples from suicide subjects showed a statistically significant increase of DNA methylation at specific CpG sites in BDNF promoter/exon IV compared with nonsuicide control subjects (P Wernicke area of the postmortem brain of suicide subjects irrespective of genome-wide methylation levels, indicating that a gene-specific increase in DNA methylation could cause or contribute to the downregulation of BDNF expression in suicide subjects. The reported data reveal a novel link between epigenetic alteration in the brain and suicidal behavior.

    Marchette, Frances Lenora

    The purpose of this mixed modal study was to compare the results of Biology Subject Area mean scores of students on a 4 x 4 block schedule, A/B block schedule, and traditional year-long schedule for 1A to 5A size schools. This study also reviewed the data to determine if minority or gender issues might influence the test results. Interviews with administrators and teachers were conducted about the type of schedule configuration they use and the influence that the schedule has on student academic performance on the Biology Subject Area Test. Additionally, this research further explored whether schedule configurations allow sufficient time for students to construct knowledge. This study is important to schools, teachers, and administrators because it can assist them in considering the impacts that different types of class schedules have on student performance and if ethnic or gender issues are influencing testing results. This study used the causal-comparative method for the quantitative portion of the study and constant comparative method for the qualitative portion to explore the relationship of school schedules on student academic achievement on the Mississippi Biology Subject Area Test. The aggregate means of selected student scores indicate that the Mississippi Biology Subject Area Test as a measure of student performance reveals no significant difference on student achievement for the three school schedule configurations. The data were adjusted for initial differences of gender, minority, and school size on the three schedule configurations. The results suggest that schools may employ various schedule configurations and expect student performance on the Mississippi Biology Subject Area Test to be unaffected. However, many areas of concern were identified in the interviews that might impact on school learning environments. These concerns relate to effective classroom management, the active involvement of students in learning, the adequacy of teacher education

    Lucatero, Carlos Rodríguez; Jaquez, Roberto Bernal; Schaum, Alexander

    2012-01-01

    The dynamics of decisions in complex networks is studied within a Markov process framework using numerical simulations combined with mathematical insight into the process mechanisms. A mathematical discrete-time model is derived based on a set of basic assumptions on the convincing mechanisms associated to two opinions. The model is analyzed with respect to multiplicity of critical points, illustrating in this way the main behavior to be expected in the network. Particular interest is focussed on the effect of social network and exogenous mass media-based influences on the decision behavior. A set of numerical simulation results is provided illustrating how these mechanisms impact the final decision results. The analysis reveals (i) the presence of fixed-point multiplicity (with a maximum of four different fixed points), multistability, and sensitivity with respect to process parameters, and (ii) that mass media have a strong impact on the decision behavior.

  15. A Subject-Specificity Analysis of Radio Channels in Wireless Body Area Networks

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available This paper presents an analysis of subject-specific radio channels in wireless body area networks (WBANs using a simulation tool based on the parallel finite-difference time-domain (FDTD technique. This technique is well suited to model radio propagations around complex, inhomogeneous objects such as the human body. The impacts of different subjects varying in size on on-body, inter-body, and off-body radio channels are studied. The analysis demonstrates that the characteristics of on-body radio channels are subject-specific and are associated with human gender, height, and body mass index. On the other hand, when waves propagate away from the body, such as in the inter-body and off-body cases, the impacts of different subjects on the channel characteristics are found to be negligible.

  17. Subjective Evaluations of Motion Area and Velocity Characteristics of Dual Manipulator in Young and Elderly People

    Science.gov (United States)

    Yoda, Mitsumasa; Yoda, Asako; Shiota, Yasuhito

    In this study, we conducted a subjective evaluation experiment of a dual manipulator, which exhibits different motion characteristics. There are three motion characteristics: two of which are age-related, and the third is a robot motion characteristic and is newly added to these two motions. The motions are evaluated from motion areas and motion velocities. Subjects are elderly and young people, and the impressions of the motions are compared in two of the different age groups by the Semantic Differential (SD) method. The obtained results indicate that there are age differences in the evaluation of three manipulator motion areas. The elderly people show a higher reliability and a higher familiarity in a robot motion area than in the other two motions. The elderly people seem to be more affected by the manipulator motion than the young people. Therefore, a careful consideration is required when planning the motion of a manipulator for elderly people.

    2011-11-01

    The impact of any prevention intervention depends on its ability to influence health risks and behavior change and the extent to which the target audience has access to and participates in the program. In this article, the authors make the case that media literacy-based tobacco prevention education can be integrated into the middle school curriculum in a way that delivers on both counts. They describe Missouri's successful development and dissemination of the Youth Empowerment in Action! Tobacco Education, Advocacy, and Media curriculum to schools serving populations that are most vulnerable to tobacco-related health disparities. They make three recommendations to support health program developers' efforts to motivate and prepare teachers to implement and sustain universal tobacco prevention education in areas of highest need.

    2017-05-01

    The rates of mineral dissolution reactions in porous media are difficult to predict, in part because of a lack of understanding of mineral reactive surface area in natural porous media. Common estimates of mineral reactive surface area used in reactive transport models for porous media are typically ad hoc and often based on average grain size, increased to account for surface roughness or decreased by several orders of magnitude to account for reduced surface reactivity of field as opposed to laboratory samples. In this study, accessible mineral surface areas are determined for a sample from the reservoir formation at the Nagaoka pilot CO2 injection site (Japan) using a multi-scale image analysis based on synchrotron X-ray microCT, SEM QEMSCAN, XRD, SANS, and FIB-SEM. This analysis not only accounts for accessibility of mineral surfaces to macro-pores, but also accessibility through connected micro-pores in smectite, the most abundant clay mineral in this sample. While the imaging analysis reveals that most of the micro- and macro-pores are well connected, some pore regions are unconnected and thus inaccessible to fluid flow and diffusion. To evaluate whether mineral accessible surface area accurately reflects reactive surface area a flow-through core experiment is performed and modeled at the continuum scale. The core experiment is performed under conditions replicating the pilot site and the evolution of effluent solutes in the aqueous phase is tracked. Various reactive surface area models are evaluated for their ability to capture the observed effluent chemistry, beginning with parameter values determined as a best fit to a disaggregated sediment experiment (Beckingham et al., 2016) described previously. Simulations that assume that all mineral surfaces are accessible (as in the disaggregated sediment experiment) over-predict the observed mineral reaction rates, suggesting that a reduction of RSA by a factor of 10-20 is required to match the core flood

    Full Text Available Craniofacial dimensions influence oral functions; however, it is not known whether they are associated with function asymmetry. The objective of this study was to evaluate chewing side preference and lateral asymmetry of occlusal contact area and bite force of individuals with different craniofacial patterns. Seventy-eight dentate subjects were divided into 3 groups according to the VERT index as follows: (1 mesofacial, (2 brachyfacial and (3 dolichofacial. Chewing side preference was evaluated using jaw tracking equipment, occlusal contact area was measured by silicon registration of posterior teeth, and bite force was measured unilaterally on molar regions using 2.25 mm-thick sensors. Statistical analysis was performed using ANOVA on Ranks, Student's t-test, and Mann-Whitney tests at a 5% significance level. Mesofacial, brachyfacial, and dolichofacial subjects presented more occlusal contact area on the left side. Only dolichofacial subjects showed lateral asymmetry for bite force, presenting higher force on the left side. No statistically significant differences were found for chewing side preference among all groups. Within the limitations of this study, it can be concluded that craniofacial dimensions play a role in asymmetry of bite force. ClinicalTrials.gov ID: NCT01286363.

  4. Numerical Treatment of Two-phase Flow in Porous Media Including Specific Interfacial Area

    KAUST Repository

    El-Amin, Mohamed

    2015-06-01

    In this work, we present a numerical treatment for the model of two-phase flow in porous media including specific interfacial area. For numerical discretization we use the cell-centered finite difference (CCFD) method based on the shifting-matrices method which can reduce the time-consuming operations. A new iterative implicit algorithm has been developed to solve the problem under consideration. All advection and advection-like terms that appear in saturation equation and interfacial area equation are treated using upwind schemes. Selected simulation results such as pc–Sw–awn surface, capillary pressure, saturation and specific interfacial area with various values of model parameters have been introduced. The simulation results show a good agreement with those in the literature using either pore network modeling or Darcy scale modeling.

    Full Text Available Abstract Background The role of inflammation in the pathogenesis and progression of atherosclerosis has been increasingly discussed. Although the seroepidemiological studies have suggested a relationship between Helicobacter pylori (H. pylori infection and atherosclerosis; the issue is still controversial. It is well known that abnormal lipid profil is related to atherosclerosis and the measurement of carotid-intima media thickness (CIMT is one of the surrogate marker of atherosclerosis. The serum concentration of high-density lipoprotein (HDL-C has been known to have an inverse correlation with the development of atherosclerosis. Paraoxonase-1 (PON1 is a major anti-atherosclerotic component of HDL-C. PON1 activity is related to lipid peroxidation and prospective cardiovascular risk. The aim of this study was to investigate CIMT and serum PON1 activities along with lipid parameters in H. pylori positive and negative subjects. Methods Thirty H. pylori positive subjects and thirty-one negative subjects were enrolled. H. pylori infection was diagnosed by the presence of positivity of stool H. pylori antigen test or Carbon 14 labeled urea breath test. Serum PON1 activity was measured spectrophotometrically. Traditional cardiovascular risk factors were investigated and laboratory analysis included measurement of serum triglycerides (TG, total cholesterol (TC, high-density lipoprotein (HDL-C and low-density lipoprotein cholesterol (LDL-C. We assessed CIMT by high-resolution ultrasound of both common carotid arteries. Results We found that the mean and maximum values of right and overall CIMT in H. pylori positive subjects were significantly thicker than those of H. pylori negative subjects. There was no significant differences in serum HDL-C, LDL-C, TC levels and TC/HDL-C ratios between two groups. Serum TG levels of H. pylori positive subjects were significantly higher than those of H. pylori negative subjects (p = 0.014. We found that PON1

Condylar volumes were calculated by using the Mimics software. The condylar volume, the area and the morphological index (MI) were compared among the three groups, by using non-parametric tests. The Kruskal-Wallis test and the Mann Whitney test revealed that: no significant difference was observed in the whole sample between the right and the left condylar volume; subjects in skeletal class III showed a significantly higher condylar volume, respect to class I and class II subjects (p condylar volume was observed in class II subjects, respect to class I and class III (p condylar volume (699.8 ± 63.07 mm3 in males and 663.5 ± 81.3 mm3 in females; p condylar surface (423.24 ± 63.03 mm2 in males and 389.76 ± 61.15 mm2 in females; p condylar volume and to the mandibular condylar area in the Caucasian orthodontic population.

    Each communication medium has particular storytelling strengths. For example, video is particularly good at illustrating a progression of events, text at background and context, and games at describing systems. In what USC's Prof. Henry Jenkins described as "transmedia storytelling," multiple media are used simultaneously, in an expansive rather than repetitive way, to better tell a single, complex story. The audience is given multiple entry points to the story, and the story is exposed to diverse and dispersed audiences, ultimately engaging a broader public. We will examine the effectiveness of a transmedia approach to communicating scientific and other complex concepts to a broad and diverse audience. Using the recently developed Educational Visitor Center at the NCAR-Wyoming Supercomputing Center as a case study, we will evaluate the reach of various means of presenting information about the geosciences, climate change and computational science. These will include an assessment of video, mechanical and digital interactive elements, animated movie segments, web-based content, photography, scientific visualizations, printed material and docent-led activities.

  9. Subject to Invent”: Adaptations of Shakespeare’s Sonnets into other Media

    Full Text Available Adaptation of Shakespeare’s plays has been part of his legacy from the beginning, as works by artists such as Nahum Tate, Henry Purcell, and John Dryden can attest. Shakespeare’s Sonnets, too, have been put to many uses over the years. They have been set to music, they have been quoted by politicians, they have been used as wedding vows, and they have appeared on greeting cards. For many, they represent the ultimate statement on love. In the four hundred years since Shakespeare’s death, they have found their way into a variety of media, including music, drama, books, television, and film. Whereas the plays have long been acknowledged as a rich source of inspiration—both serious and parodic—by artists and auteurs, ranging in kind from novelist James Joyce to dramatist Tom Stoppard to comedian Ben Elton, the poems have received less scrutiny in this regard. However, they represent a gold mine of untold riches, especially in terms of biography, which has yet to be sufficiently tapped. In this paper I take a look at the various uses the sonnets have been put to, primarily in books, television, and film, and come to some conclusions regarding their success in remediation.

    The aim of this study was to characterize the leading topics in respiratory system in Spain through a bibliometric analysis. For identify and characterize the performance of the different research topics in respiratory system in Spain, we compile the production using a journal that turn out representative of a broad group of researcher. In this sense the journal Archivos de Bronconeumología is the most important publication in Spanish language of this field. A total of 2198 articles published in Archivos Bronconeumología from 1970 to 2000 were analyzed. In each three decades, we did not found differences except in the productivity index in oncology in the eighty decade and in respiratory failure and sleep disturbance (RFSD) and oncology areas in the ninetieth decade and in the Price index (consumption indicators) in the diagnostic and therapeutic techniques area in seventy decade. When we compare the productivity index of each subject areas between decades, we found a significant production increase in the ninetieth decade in asthma, RFSD, tuberculosis, non tuberculosis infection, circulation, oncology, pleural disease and interstitial areas versus the same in seventy decade, and also, we found significant differences between ninetieth and eighty decades in the asthma, RFSD, non tuberculosis infection, circulation and pleural disease areas. Tuberculosis area maintains an insularity index higher than the other areas. We also found a progressive increase in the insularity index of RFSD, non tuberculosis infection, oncology and interstitial disease areas. In general all the indicators maintains stable although the more productivity topics were respiratory failure and sleep disturbances, and oncology. The productivity has increased in asthma, respiratory failure and sleep disturbances, tuberculosis, non - tuberculosis respiratory infections, oncology, pulmonary circulation, pleura and interstitial disease.

    The study aimed to determine the prevalence and profile of otitis media in different parts of a city, i.e. non-slum urban areas, urban slums and rural areas. A door to door survey was conducted in identified areas of Delhi. A total of 3000 children (0-15 years) were randomly selected and examined for presence of otitis media. These children were equally distributed in the three areas under consideration. Data was analyzed to establish the prevalence of different types of otitis media. Chi-square test was then applied to compare disease prevalence among the three areas. 7.1% of the study population was identified with otitis media, which includes CSOM (4.26%), OME (2.5%) and ASOM (0.4%). In the non-slum urban parts of the city, 4.6% children had otitis media. This was significantly lower compared to 7% children in rural parts of Delhi and 9.9% in urban slums of the city. The prevalence of CSOM was considerably higher in slum areas (7.2%) as compared with rural (3%) and non-slum urban areas (2.6%). Ear infections are significantly more common in urban slums as compared to non-slum city areas and rural parts of Delhi. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Charismatic megafauna are arguably considered the primary attractor of ecotourists to sub-Saharan African protected areas. However, the lack of visitation data across the whole continent has thus far prevented the investigation of whether charismatic species are indeed a key attractor of ecotourists to protected areas. Social media data can now be used for this purpose. We mined data from Instagram, and used generalized linear models with site- and country-level deviations to explore which socio-economic, geographical and biological factors explain social media use in sub-Saharan African protected areas. We found that charismatic species richness did not explain social media usage. On the other hand, protected areas that were more accessible, had sparser vegetation, where human population density was higher, and that were located in wealthier countries, had higher social media use. Interestingly, protected areas with lower richness in non-charismatic species had more users. Overall, our results suggest that more factors than simply charismatic species might explain attractiveness of protected areas, and call for more in-depth content analysis of the posts. With African countries projected to develop further in the near-future, more social media data will become available, and could be used to inform protected area management and marketing.

    A human blood biomonitoring campaign to detect the environmental exposure to metals (Cd, Cu, Cr, Mn, Pb and Zn) in 265 subjects was performed in the South-Western part of Sardinia (an Italian island) that is a particular area with a great history of coal and metal mining (Pb/Zn mainly) activities and large industrial structures (as metallurgy). Subjects living near the industrial plant area had geometric means (GM) of blood Cd (0.79 μg/l), Cu (971 μg/l), Mn (12.2 μg/l), and Pb (55.7 μg/l) significantly higher than controls (Cd, 0.47 μg/l; Cu, 900 μg/l; Mn 9.98 μg/l; Pb, 26.5 μg/l) and than people living nearby the past mining sites. Subjects living next to one dismissed mine were statistically higher in blood Cu (GM, 1,022 μg/l) and Pb (GM, 41.4 μg/l) concentrations than controls. No differences were observed in people living in the different mining sites, and this might be related to the decennial disclosure of mines and the adoption of environmental remediation programmes. Some interindividual variables influenced blood biomonitoring data, as smoke and age for Cd, gender for Cu, age, sex and alcohol for Pb, and age for Zn. Moreover, blood metal levels of the whole population were similar to reference values representative of the Sardinian population and acceptably safe according to currently available health guidelines.

    Short-stature homeobox (SHOX) gene haploinsufficiency may cause skeletal dysplasia including Léri-Weill Dyschondrosteosis (LWD), a clinical entity characterised by the triad of low height, mesomelic disproportion and Madelung's deformity of the wrist. Bone microarchitecture and estimated strength in adult SHOX mutation carriers have not been examined. Twenty-two subjects with a SHOX mutation including 7 males and 15 females with a median age of 38.8 [21.1-52.2] years were recruited from five unrelated families. The control group consisted of 22 healthy subjects matched on age and sex. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Bone geometry, volumetric density, microarchitecture and finite element estimated (FEA) bone strength were measured using high-resolution peripheral quantitative computed tomography (HR-pQCT). A full region of interest (ROI) image analysis and height-matched ROI analyses adjusting for differences in body height between the two groups were performed. Areal BMD and T-scores showed no significant differences between cases and controls. Total radius area was smaller in cases than controls (207 [176-263] vs. 273 [226-298] mm, pRadius cortical bone area (74 ± 20 vs. 58 ± 17 mm(2), p=0.01) and thickness (1.16 ± 0.30 vs. 0.84 ± 0.26 mm, pRadius trabecular bone area (119 [103-192] vs. 202 [168-247] mm(2), pradius and tibia cortical porosity or FEA failure load between groups. A segment of cortical bone defect was identified in the distal radius adjacent to ulna in five unrelated SHOX mutation carriers. Subjects with a SHOX mutation presented with a different bone geometry in radius and tibia while there were no differences in BMD or failure load compared to controls, suggesting that mutations in SHOX gene may have an impact on bone microarchitecture albeit not bone strength.

    AIM To evaluate the distribution of refractive error in young subjects in a rural area of Paraguay in the context of an international cooperation campaign for the prevention of blindness. METHODS A sample of 1466 young subjects (ranging from 3 to 22 years old), with a mean age of 11.21±3.63 years old, were examined to assess their distance visual acuity (VA) and refractive error. The first screening examination performed by trained volunteers, included visual acuity testing, autokeratometry and non-cycloplegic autorefraction. Inclusion criteria for a second complete cycloplegic eye examination by an optometrist were VA <20/25 (0.10 logMAR or 0.8 decimal) and/or corneal astigmatism ≥1.50 D. RESULTS An uncorrected distance VA of 0 logMAR (1.0 decimal) was found in 89.2% of children. VA <20/25 and/or corneal astigmatism ≥1.50 D was found in 3.9% of children (n=57), with a prevalence of hyperopia of 5.2% (0.2% of the total) in this specific group. Furthermore, myopia (spherical equivalent ≤-0.5 D) was found in 37.7% of the refracted children (0.5% of the total). The prevalence of refractive astigmatism (cylinder ≤-1.50 D) was 15.8% (0.6% of the total). Visual impairment (VI) (0.05≤VA≤0.3) was found in 12/114 (0.4%) of the refracted eyes. Main causes for VI were refractive error (58%), retinal problems (17%, 2/12), albinism (17%, 2/12) and unknown (8%, 1/12). CONCLUSION A low prevalence of refractive error has been found in this rural area of Paraguay, with higher prevalence of myopia than of hyperopia. PMID:28393041

    When deposited on land the vinasse can promote improvement in fertility, however, often fertilizer application occurs in areas considered homogeneous, without taking into account the variability of the soil. The objective of this study was to evaluate the effect of vinasse application on potassium content in two classes of soils cultivated with sugarcane, and characterize the spatial variability of soil using geostatistical techniques. In the 2010 and 2011 crop year, soil samples were collected from an experimental grid at 0-0.2 and 0.2-0.4 m depth in three soils cultivated with sugarcane, totaling 90 samplings in each grid, for the determination of pH, calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), aluminum (Al) and potential acidity (H + Al). The data have been submitted to analysis of descriptive statistics and the K attribute was subjected to geostatistical analysis. The coefficient of variation indicated medium and high variability of K for the three soils. The results showed that the spatial dependence of K increased in depth to FRce and decreased to PHlv, indicating that the attribute could have followed the pattern of distribution of clay in depth. The investigation of the spatial variability of K on the surface and subsurface soils provided the definition of management zones with different levels of fertility, which can be organized into sub-areas for a more efficient management of the resources and the environment.

    Full Text Available The paper deals with domain-driven design applicability of information systems for client queuing subject areas. The following optimality criteria were put forward for the final implementation: the possibility of automation with a single system both for small institution and a whole network of institutions; advanced graphical interface with support for sensor screens; implementation of multi-users account of orders from clients; flexible application architecture with the ability of future enhancement; ability of integration with a variety of peripherals. The necessity of each criterion definition is shown. For implementability estimation, test information system was designed, automating the queuing system. Unified modeling language UML is used. Description of each class functionality is given and the association with other classes as well. Attention is paid to the design of tree (hierarchical structures and selection procedure of base classes based on the analysis of existing common attributes. For the system implementation, its own development environment SharpArchitect RAD Studio is used, offering MDA approach for implementation of systems based on standardized meta object system. A graphical view of order form developed prototype is presented, composition and structure are described, and notation developed by the author is given simplifying the prototyping process. Approaches to differentiation of access rights for different user roles are shown. Conformity of the received implementation to each selected optimality criterion is determined. Recommendations for further system development are given.

    Social media data is increasingly used as a proxy for human activity in different environments, including protected areas, where collecting visitor information is often laborious and expensive, but important for management and marketing. Here, we compared data from Instagram, Twitter and Flickr, and assessed systematically how park popularity and temporal visitor counts derived from social media data perform against high-precision visitor statistics in 56 national parks in Finland and South Africa in 2014. We show that social media activity is highly associated with park popularity, and social media-based monthly visitation patterns match relatively well with the official visitor counts. However, there were considerable differences between platforms as Instagram clearly outperformed Twitter and Flickr. Furthermore, we show that social media data tend to perform better in more visited parks, and should always be used with caution. Based on stakeholder discussions we identified potential reasons why social media data and visitor statistics might not match: the geography and profile of the park, the visitor profile, and sudden events. Overall the results are encouraging in broader terms: Over 60% of the national parks globally have Twitter or Instagram activity, which could potentially inform global nature conservation.

    In today's life, social media offer new working ways. People are increasingly expanding interactions from face-to-face meetings to online ways of communication, networking, searching, creating and sharing information, and furthermore taking care of patients/citizens via tweeting care, Facebook care, blogging care, vlogging care, infotainment care, gamification-care, infographic care, for instance. This chapter discusses the utilisation of social media in the healthcare domain including nursing education, practice and research. When in the current healthcare era, social media is used effectively and purposefully, it can give all of us a greater choice in how we live, how we take care of our health and how we learn and build both our professional competences and produce evidence-based, qualified data. Nurses need continuous education and proper tools to take the most of the benefits of social media, not forgetting privacy and ethical issues. This use of social media in professional nursing generates the need for new competences.

    The levels of heavy metals in Shanghai drinking water conservation area were determined, and the spatial distributions and main sources of heavy metals were investigated. Moreover, the ecological risk assessment of heavy metals was conducted. Some conclusions can be drawn as follows: (1) The average concentrations of Cd, Hg, Pb, Cu, Zn, Ni, Cr and As in road dust were 0.80, 0.23, 148.45, 127.52, 380.57, 63.17, 250.38 and 10.37 mg x kg(-1) respectively. In terms of the pollution level, the values of soils were relatively lower, with the mean contents of 0.16 (Cd), 0.33 (Hg), 30.14 (Pb), 30.66 (Cu), 103.79 (Zn), 24.04 (Ni), 65.75 (Cr) and 6.31 mg x kg(-1) (As) severally; meanwhile the average levels of heavy metals in vegetables were 0.010 (Cd), 0.016 (Hg), 0.36 (Pb), 12.80 (Cu), 61.69 (Zn), 2.04 (Ni), 2.41 (Cr) and 0.039 mg x kg(-1) (As) respectively. (2) Semivariogram and multivariate analysis indicated that heavy metals pollution of soils was induced by anthropogenic activities mostly, and the pollutants produced by traffic were the major source of heavy metals in road dust. (3) The order for heavy metal enrichment coefficients of vegetables was as following: Zn (0.589) > Cu (0.412) > 0.102 (Ni) > Cd (0.059) > Cr (0.061) > Hg (0.056) > Pb (0.012) > As (0.007), and the results indicated that Cd and Zn in vegetables were mainly from the soils, and the other metals were probably from the pollutants in the atmosphere. (4) Sediments in drinking water conservation area were probably derived from soils around; however, there was no significant relationship between heavy metals contents of them. (5) The results of ecological risk assessment of heavy metals showed that heavy metals in soils were in no-warning to warning situation, and warning to light-warning situation for road dust and vegetables. The fuzzy synthesis judgment for all the environmental media around drinking water conservation area was warning to light-warning.

We therefore investigated the correlation between leukocyte subtype counts and intima-media thickness of the common carotid artery (CCA-IMT) in subjects with type 2 diabetes. Methods This cross-sectional study involved 484 in-patients with type 2 diabetes (282 males and 202 females), who were hospitalized for glycemic control and underwent carotid ultrasonography at Kumamoto University Hospital between 2005 and 2011. Mean and maximum CCA-IMT was measured by high-resolution B-mode ultrasonography. Results Univariate analyses revealed that mean CCA-IMT was positively correlated with age, systolic blood pressure, brachial-ankle pulse wave velocity (PWV), urinary albumin excretion and duration of diabetes, but was negatively correlated with diastolic blood pressure and fasting plasma glucose. Maximum CCA-IMT was positively and negatively correlated with the same factors as mean CCA-IMT except for fasting plasma glucose. Mean CCA-IMT was positively correlated with total leukocyte (r = 0.124, p = 0.007), monocyte (r = 0.373, p leukocyte (r = 0.154, p < 0.001), monocyte (r = 0.398, p < 0.001), neutrophil (r = 0.152, p < 0.001) and basophil counts (r = 0.102, p = 0.027). Multiple regression analyses showed that monocyte count, age and PWV were significant and independent factors associated with mean CCA-IMT (adjusted R2 = 0.239, p < 0.001), and that monocyte count, age and urinary albumin excretion were significant and independent factors associated with maximum CCA-IMT (adjusted R2 = 0.277, p < 0.001). Conclusions Monocyte counts were positively correlated with both mean CCA-IMT and maximum CCA-IMT in patients with type 2 diabetes. Monocyte count may be a useful predictor of

    This study aimed to describe sleep patterns and to examine the association between short sleep time and family relationships and the availability of media devices among adolescents. A cross-sectional study based on a self-reported questionnaire was performed among a representative sample of adolescents (13-19 years old) enrolled during the 2011-2012 academic year in high schools in Barcelona, Spain. Adolescents reported sleep patterns and family-related variables such as family relationships, the availability of media devices in the bedroom, and watching television at dinner. Sleep time was then calculated from sleep patterns. Multivariate Poisson regression analyses with robust variance were conducted to determine the association between short sleep time (students were girls (mean age: 15.9 years). Sleep time was shorter than recommended on school days in almost half of the compulsory schooling students and in around 75% of post-compulsory schooling students. More than 80% of adolescents had at least one media device (television, console, or computer) in their bedroom. Adolescents with a computer in their bedroom and with poorer family relationships were more likely to be short sleepers. In boys, frequently watching TV at dinner and living in a disorganized family were also associated with short sleep time. There is a high prevalence of short sleepers. Media availability, media use and family relationships should be considered in multi-component educational interventions addressed to both adolescents and parents to reduce short sleep time.

    To assess the reproducibility and repeatability of foveal avascular zone (FAZ) area measurements using swept-source optical coherence tomography angiography (SS-OCTA) in healthy subjects. Sixty-four eyes of 64 healthy volunteers were randomly subjected to FAZ area measurements using SS-OCTA by 2 examiners in 2 different sessions. The FAZ areas measured by the first and second observer were 0.269 ± 0.092 mm2 and 0.270 ± 0.090 mm2, respectively. Within subjects, the coefficients of variations were 2.44% (95% confidence interval [CI] 1.95% to 2.93%) and 2.66% (95% CI 2.00% to 3.31%) for the first and second observers, respectively. The coefficient of repeatability average measurements of FAZ area were 0.021 mm2 and 0.024 mm2. The intraclass correlation coefficient values were 0.993 (95% CI 0.989 to 0.996) and 0.991 (95% CI 0.986 to 0.995). Interobserver and intraobserver concordance correlation coefficients ranged from 0.998 (95% CI 0.997 to 0.999) to 0.999 (95% CI 0.998 to 0.999) and from 0.989 (95% CI 0.982 to 0.993) to 0.987 (95% CI 0.979 to 0.992), respectively. The FAZ area measurements by means of SS-OCTA showed high reproducibility and repeatability in healthy eyes.

    Full Text Available Cross-modal activity in visual cortex of blind subjects has been reported during performance of variety of non-visual tasks. A key unanswered question is through which pathways non-visual inputs are funneled to the visual cortex. Here we used tomographic analysis of single trial magnetoencephalography (MEG data recorded from one congenitally blind and two sighted subjects after stimulation of the left and right median nerves at three intensities: below sensory threshold, above sensory threshold and above motor threshold; the last sufficient to produce thumb twitching. We identified reproducible brain responses in the primary somatosensory (S1 and motor (M1 cortices at around 20 ms post-stimulus, which were very similar in sighted and blind subjects. Time-frequency analysis revealed strong 45 to 70 Hz activity at latencies of 20 to 50 ms in S1 and M1, and posterior parietal cortex Brodmann areas (BA 7 and 40, which compared to lower frequencies, were substantially more pronounced in the blind than the sighted subjects. Critically, at frequencies from α-band up to 100 Hz we found clear, strong and widespread responses in the visual cortex of the blind subject, which increased with the intensity of the somatosensory stimuli. Time-delayed mutual information (MI revealed that in blind subject the stimulus information is funneled from the early somatosensory to visual cortex through posterior parietal BA 7 and 40, projecting first to visual areas V5 and V3, and eventually V1. The flow of information through this pathway occured in stages characterized by convergence of activations into specific cortical regions. In sighted subjects, no linked activity was found that led from the somatosensory to the visual cortex through any of the studied brain regions. These results provide the first evidence from MEG that in blind subjects, tactile information is routed from primary somatosensory to occipital cortex via the posterior parietal cortex.

    Modern sign languages used by deaf people are fully expressive, natural human languages that are perceived visually and produced manually. The literature contains little data concerning human brain organization in conditions of deficient sensory information such as deafness. A deaf-mute patient underwent surgery of a left temporoinsular low-grade glioma. The patient underwent awake surgery with intraoperative electrical stimulation mapping, allowing direct study of the cortical and subcortical organization of sign language. We found a similar distribution of language sites to what has been reported in mapping studies of patients with oral language, including 1) speech perception areas inducing anomias and alexias close to the auditory cortex (at the posterior portion of the superior temporal gyrus and supramarginal gyrus); 2) speech production areas inducing speech arrest (anarthria) at the ventral premotor cortex, close to the lip motor area and away from the hand motor area; and 3) subcortical stimulation-induced semantic paraphasias at the inferior fronto-occipital fasciculus at the temporal isthmus. The intraoperative setup for sign language mapping with intraoperative electrical stimulation in deaf-mute patients is similar to the setup described in patients with oral language. To elucidate the type of language errors, a sign language interpreter in close interaction with the neuropsychologist is necessary. Sign language is perceived visually and produced manually; however, this case revealed a cross-modal recruitment of auditory and orofacial motor areas. Copyright © 2017 Elsevier Inc.

    A new experimental method was developed to determine air-water interfacial area as a function of capillary pressure and water saturation in unsaturated porous media. The surfactant sodium dodecyl benzene sulfonate (SDBS) was used in equilibrium column adsorption experiments to estimate air-water interfacial area for water saturations (milliliter water per milliliter void) ranging from 0.05 to 1.0 and pressures ranging from 0 to 20 cm of water. A comparison was made between columns which were equilibrated under gravity drainage versus columns equilibrated under secondary imbibition. Gravity drainage experiments showed the air-water interfacial area decreased linearly with saturation, while imbibition experiments showed a more complex nonmonotonic relation to the saturation. The interfacial area data are then compared with existing network models.

    Models and data used to describe species–area relationships confound sampling with ecological process as they fail to acknowledge that estimates of species richness arise due to sampling. This compromises our ability to make ecological inferences from and about species–area relationships. We develop and illustrate hierarchical community models of abundance and frequency to estimate species richness. The models we propose separate sampling from ecological processes by explicitly accounting for the fact that sampled patches are seldom completely covered by sampling plots and that individuals present in the sampling plots are imperfectly detected. We propose a multispecies abundance model in which community assembly is treated as the summation of an ensemble of species-level Poisson processes and estimate patch-level species richness as a derived parameter. We use sampling process models appropriate for specific survey methods. We propose a multispecies frequency model that treats the number of plots in which a species occurs as a binomial process. We illustrate these models using data collected in surveys of early-successional bird species and plants in young forest plantation patches. Results indicate that only mature forest plant species deviated from the constant density hypothesis, but the null model suggested that the deviations were too small to alter the form of species–area relationships. Nevertheless, results from simulations clearly show that the aggregate pattern of individual species density–area relationships and occurrence probability–area relationships can alter the form of species–area relationships. The plant community model estimated that only half of the species present in the regional species pool were encountered during the survey. The modeling framework we propose explicitly accounts for sampling processes so that ecological processes can be examined free of sampling artefacts. Our modeling approach is extensible and could be applied

    Full Text Available One of the main problems in clinical practice and academic research is how to localize speech zones in the human brain. Two speech areas (Broca and Wernicke areas that are responsible for language production and for understanding of written and spoken language have been known since the past century. Their location and even hemispheric lateralization have a substantial inter-individual variability, especially in neurosurgery patients. Wada test is one of the most frequently used invasive methodology for speech hemispheric lateralization in neurosurgery patients. However, besides relatively high-risk of Wada test for patient's health, it has its own limitation, e. g. low reliability of Wada-based evidence of verbal memory brain lateralization. Therefore, there is an urgent need for non-invasive, reliable methods of speech zones mapping.The current review summarizes the recent experimental evidence from magnitoencephalographic (MEG research suggesting that speech areas are included in the speech processing within the first 200 ms after the word onset. The electro-magnetic response to deviant word, mismatch negativity wave with latency of 100—200 ms, can be recorded from auditory cortex within the oddball-paradigm. We provide the arguments that basic features of this brain response, such as its automatic, pre-attentive nature, high signal to noise ratio, source localization at superior temporal sulcus, make it a promising vehicle for non-invasive MEG-based speech areas mapping in neurosurgery.

We disseminated messages emphasizing the health risks of SSBs through television, digital channels, and local organizations over 15 weeks in 2015-2016 in the Tri-Cities region of northeast Tennessee, southwest Virginia, and southeast Kentucky. We evaluated the campaign with pre- and post-telephone surveys of adults aged 18 to 45 years in the intervention area and by examining changes in beverage sales in the intervention and a matched comparison area in western Virginia. Fifty-four percent of postcampaign respondents recalled seeing a campaign advertisement. After the campaign, 53% of respondents believed SSBs were a cause of heart disease, and respondents were more likely postcampaign to consider SSBs a "big cause of diabetes" (75% vs 60%; P campaign, SSB sales decreased 3.4%, including a 4.1% decrease in soda sales in the intervention area relative to the comparison area (P campaign on SSBs was followed by intended changes in beliefs and consumption. Public Health Implications. Additional media campaigns on SSBs should be attempted and evaluated.

    Deep brain stimulation (DBS) in the pedunculopontine tegmental nucleus (PPTg) has been proposed to alleviate medically intractable gait difficulties associated with Parkinson's disease. Clinical trials have shown somewhat variable outcomes, stemming in part from surgical targeting variability, modulating fiber pathways implicated in side effects, and a general lack of mechanistic understanding of DBS in this brain region. Subject-specific computational models of DBS are a promising tool to investigate the underlying therapy and side effects. In this study, a parkinsonian rhesus macaque was implanted unilaterally with an 8-contact DBS lead in the PPTg region. Fiber tracts adjacent to PPTg, including the oculomotor nerve, central tegmental tract, and superior cerebellar peduncle, were reconstructed from a combination of pre-implant 7T MRI, post-implant CT, and post-mortem histology. These structures were populated with axon models and coupled with a finite element model simulating the voltage distribution in the surrounding neural tissue during stimulation. This study introduces two empirical approaches to evaluate model parameters. First, incremental monopolar cathodic stimulation (20 Hz, 90 μs pulse width) was evaluated for each electrode, during which a right eyelid flutter was observed at the proximal four contacts (−1.0 to −1.4 mA). These current amplitudes followed closely with model predicted activation of the oculomotor nerve when assuming an anisotropic conduction medium. Second, PET imaging was collected OFF-DBS and twice during DBS (two different contacts), which supported the model predicted activation of the central tegmental tract and superior cerebellar peduncle. Together, subject-specific models provide a framework to more precisely predict pathways modulated by DBS. PMID:26236229

    The dense non-aqueous phase liquid (DNAPL)-water interfacial area and DNAPL saturation are key factors in groundwater pollution remediation. The research methods of DNAPL-water interfacial area were summarized, including interfacial partitioning tracer tests, synchrotron X-ray microtomography and theoretical models, and the disparity of the study results with different methods was analyzed. The applications of DNAPL saturation measurement methods including tracer test method, light transmission visualization (LTV) and electrical resistivity tomography (ERT) were also summarized, especially the current applications of light transmission method in China. The partitioning tracer test, as an important method in the study of correlation between DNAPL-water interfacial areas and DNAPL saturation for porous media systems, should be given more attention in laboratory and field experiments.

    Rivers, lakes and the sea were the natural receivers of raw urban waste and storm waters for a long time but the low sustainability of such practice, the increase of population and a renewed environmental sensibility increased researcher interest in the analysis and mitigation of the impact of urban waters on receiving water bodies (RWB). In Europe, the integrated modelling of drainage systems and RWB has been promoted as a promising approach for implementing the Water Framework Directive. A particular interest is given to the fate of pathogens and especially of Escherichia coli, in all the cases in which an interaction between population and the RWB is foreseen. The present paper aims to propose an integrated water quality model involving the analysis of several sewer systems (SS) discharging their polluting overflows on the coast in a sensitive marine environment. From a modelling point of view, the proposed application integrated one-dimensional drainage system models with a complex three-dimensional model analysing the propagation in space and time of E. coli in the coastal marine area. The integrated approach was tested in a real case study (the Acicastello bay in Italy) where data were available both for SS model and for RWB propagation model calibration. The analysis shows a good agreement between the model and monitored data. The integrated model was demonstrated to be a valuable tool for investigating the pollutant propagation and to highlight the most impacted areas.

    Coastal sand dunes are among the most threatened habitats, especially in the Mediterranean Basin, where the high levels of human pressure impair the presence of plant species, putting at risk the maintenance of the ecosystem services, such as CO2 sequestration provided by these habitats. The aim of this study was to analyze how disturbance-induced changes in plant species abundance patterns account for variations in annual CO2 sequestration flow (CS) of Mediterranean sand dune areas. Two sites characterized by a high (site HAD) and a lower (site LAD) anthropogenic disturbance level were selected. At both sites, plant species number, cover, height and CS based on net photosynthesis measurements were sampled. At the plant species level, our results highlighted that Ammophila arenaria and Pancratium maritimum, had a key role in CS. Moreover, the results revealed a patchy species assemblage in both sites. In particular, HAD was characterized by a higher extension of the anthropogenic aphytoic zone (64% of the total transect length) than LAD. In spite of the observed differences in plant species composition, there were not significant differences between HAD and LAD in structural and functional traits, such as plant height and net photosynthesis. As a consequence, HAD and LAD had a similar CS (443 and 421 Mg CO2 ha-1 y-1, respectively). From a monetary point of view, our estimates based on the social costs of carbon revealed that the flow of sequestered CO2 valued on an average 3181 ± 114 ha-1 year-1 (mean value for the two sites). However, considering also the value of the CO2 negative flow related to loss of vegetated area, the annual net benefit arising from CO2 sequestration amounted to 1641 and 1772 for HAD and LAD, respectively. Overall, the results highlighted the importance to maximize the efforts to preserve dune habitats by applying an effective management policy, which could allow maintaining also a regulatory ecosystem service such as CO2 sequestration.

    Subjective well-being (SWB) of older adults could be affected by both individual and community characteristics. However, the effect of community characteristics, such as population aging in local areas, remains unclear. This study examined the cross-sectional and longitudinal associations between the area-level population aging and SWB of older individuals from two distinct surveys. Those analyzed were 572 respondents aged 75 years and older for a cross-sectional survey in a metropolitan area in Tokyo, Japan (Study 1) and 1,257 and 859 respondents for a cross-sectional and longitudinal analysis, respectively, for a 2-year longitudinal survey project in urban and rural areas of Fukui Prefecture (Study 2). Area-level population aging was assessed by the number of people aged 65 years or older per 100 residents. SWB was assessed with the Life Satisfaction Index-A (LSIA). Multilevel analysis was performed to examine unconditional and conditional associations between the area-level number of older adults per 100 residents and the individual-level LSIA scores. The area-level number of older adults per 100 residents was significantly and positively associated with the LSIA scores in Study 1 (p = 0.042), even after controlling for the area- and individual-level covariates. In Study 2, we also found a significant effect of the area-level number of older adults per 100 residents on LSIA scores in the longitudinal multivariate analysis (p = 0.049). Findings from two survey projects suggested cross-validity in the positive effect of area-level population aging on older adults' SWB. Policymakers should consider older citizens' SWB in the recent urban-to-rural migration governmental policy as well as in urban renovation planning.

    Full Text Available Purpose. To assess differences in translaminar pressure gradient (TPG and neuroretinal rim area (NRA in patients with normal tension glaucoma (NTG, high tension glaucoma (HTG, and healthy controls. Methods. 27 patients with NTG, HTG, and healthy controls were included in the prospective pilot study (each group consisted of 9 patients. Intraocular pressure (IOP, intracranial pressure (ICP, and confocal laser scanning tomography were assessed. TPG was calculated as the difference of IOP minus ICP. ICP was measured using noninvasive two-depth transcranial Doppler device. The level of significance P 0.05. The difference between TPG for healthy (5.4(7.7 mmHg and glaucomatous eyes (NTG 6.3(3.1 mmHg, HTG 15.7(7.7 mmHg was statistically significant (P < 0.001. Higher TPG was correlated with decreased NRA (r = −0.83; P = 0.01 in the NTG group. Conclusion. Translaminar pressure gradient was higher in glaucoma patients. Reduction of NRA was related to higher TPG in NTG patients. Further prospective studies are warranted to investigate the involvement of TPG in glaucoma management.

    Optoelectronic tweezers (OET) has advanced within the past decade to become a promising tool for cell and microparticle manipulation. Its incompatibility with high conductivity media and limited throughput remain two major technical challenges. Here a novel manipulation concept and corresponding platform called Self-Locking Optoelectronic Tweezers (SLOT) are proposed and demonstrated to tackle these challenges concurrently. The SLOT platform comprises a periodic array of optically tunable phototransistor traps above which randomly dispersed single cells and microparticles are self-aligned to and retained without light illumination. Light beam illumination on a phototransistor turns off the trap and releases the trapped cell, which is then transported downstream via a background flow. The cell trapping and releasing functions in SLOT are decoupled, which is a unique feature that enables SLOT's stepper-mode function to overcome the small field-of-view issue that all prior OET technologies encountered in manipulation with single-cell resolution across a large area. Massively parallel trapping of more than 100,000 microparticles has been demonstrated in high conductivity media. Even larger scale trapping and manipulation can be achieved by linearly scaling up the number of phototransistors and device area. Cells after manipulation on the SLOT platform maintain high cell viability and normal multi-day divisibility.

    Assessment of synovitis in the metatarsophalangeal (MTP) joints with ultrasound has been shown to improve the accuracy of assessment of rheumatoid arthritis (RA). However, the presence of intraarticular low-echoic synovial area (LESA) in the MTP joints in healthy subjects complicates the sonographic assessment of these joints. Healthy subjects with no arthritic symptoms in their MTP joints were recruited. All subjects completed a questionnaire and underwent physical examination and sonographic assessment. LESAs in the dorsal aspect of all MTP joints were measured in the longitudinal view. One thousand non-arthritic MTP joints in 100 healthy subjects (female 73, mean age 41.0 years old) were evaluated. Measurable LESAs were identified in all joints assessed. Mean length of LESA in each of the 1st-5th MTP joints was 17.8, 13.9, 11.9, 10.6, and 9.2 mm, respectively, whereas mean thickness was 2.4, 2.4, 1.8, 1.2, and 0.8 mm, respectively. Multivariate linear regression models identified the difference between 1st and 5th MTP joints as the most independently influential factor on the measurement of LESA. Our data provide the normal reference values for the measurements of LESA in Japanese, which should be taken into consideration when the synovitis in MTP joints is evaluated with ultrasound.

    To compare optic disc area measurement between optic nerve head drusen (ONHD) and control subjects using fundus photography, time-domain optical coherence tomography (TD-OCT) and spectral-domain optical coherence tomography (SD-OCT). We also made a comparison between each of the three techniques. We performed our study on 66 eyes (66 patients) with ONHD and 70 healthy control subjects (70 controls) with colour ocular fundus photography at 20º (Zeiss FF 450 IR plus), TD-OCT (Stratus OCT) with the Fast Optic Disc protocol and SD-OCT (Cirrus OCT) with the Optic Disc Cube 200 × 200 protocol for measurement of the optic disc area. The measurements were made by two observers and in each measurement a correction of the image magnification factor was performed. Measurement comparison using the Student's t-test/Mann-Whitney U test, the intraclass correlation coefficient, Pearson/Spearman rank correlation coefficient and the Bland-Altman plot was performed in the statistical analysis. Mean and standard deviation (SD) of the optic disc area in ONHD and in controls was 2.38 (0.54) mm(2) and 2.54 (0.42) mm(2), respectively with fundus photography; 2.01 (0.56) mm(2) and 1.66 (0.37) mm(2), respectively with TD-OCT, and 2.03 (0.49) mm(2) and 1.75 (0.38) mm(2), respectively with SD-OCT. In ONHD and controls, repeatability of optic disc area measurement was excellent with fundus photography and optical coherence tomography (TD-OCT and SD-OCT), but with a low degree of agreement between both techniques. Optic disc area measurement is smaller in ONHD compared to healthy subjects with fundus photography, unlike time-domain and spectral-domain optical coherence tomography in which the reverse is true. Both techniques offer good repeatability, but a low degree of correlation and agreement, which means that optic disc area measurement is not interchangeable or comparable between techniques.

    Full Text Available Perception of natural visual scenes activates several functional areas in the human brain, including the Parahippocampal Place Area (PPA, Retrosplenial Complex (RSC, and the Occipital Place Area (OPA. It is currently unclear what specific scene-related features are represented in these areas. Previous studies have suggested that PPA, RSC, and/or OPA might represent at least three qualitatively different classes of features: (1 2D features related to Fourier power; (2 3D spatial features such as the distance to objects in a scene; or (3 abstract features such as the categories of objects in a scene. To determine which of these hypotheses best describes the visual representation in scene-selective areas, we applied voxel-wise modeling (VM to BOLD fMRI responses elicited by a set of 1,386 images of natural scenes. VM provides an efficient method for testing competing hypotheses by comparing predictions of brain activity based on encoding models that instantiate each hypothesis. Here we evaluated three different encoding models that instantiate each of the three hypotheses listed above. We used linear regression to fit each encoding model to the fMRI data recorded from each voxel, and we evaluated each fit model by estimating the amount of variance it predicted in a withheld portion of the data set. We found that voxel-wise models based on Fourier power or the subjective distance to objects in each scene predicted much of the variance predicted by a model based on object categories. Furthermore, the response variance explained by these three models is largely shared, and the individual models explain little unique variance in responses. Based on an evaluation of previous studies and the data we present here, we conclude that there is currently no good basis to favor any one of the three alternative hypotheses about visual representation in scene-selective areas. We offer suggestions for further studies that may help resolve this issue.

    Full Text Available In the rapidly changing circumstances of our increasingly digital world, reading is also becoming an increasingly digital experience: electronic books (e-books are now outselling print books in the United States and the United Kingdom. Nevertheless, many readers still view e-books as less readable than print books. The present study thus used combined EEG and eyetracking measures in order to test whether reading from digital media requires higher cognitive effort than reading conventional books. Young and elderly adults read short texts on three different reading devices: a paper page, an e-reader and a tablet computer and answered comprehension questions about them while their eye movements and EEG were recorded. The results of a debriefing questionnaire replicated previous findings in that participants overwhelmingly chose the paper page over the two electronic devices as their preferred reading medium. Online measures, by contrast, showed shorter mean fixation durations and lower EEG theta band voltage density--known to covary with memory encoding and retrieval--for the older adults when reading from a tablet computer in comparison to the other two devices. Young adults showed comparable fixation durations and theta activity for all three devices. Comprehension accuracy did not differ across the three media for either group. We argue that these results can be explained in terms of the better text discriminability (higher contrast produced by the backlit display of the tablet computer. Contrast sensitivity decreases with age and degraded contrast conditions lead to longer reading times, thus supporting the conclusion that older readers may benefit particularly from the enhanced contrast of the tablet. Our findings thus indicate that people's subjective evaluation of digital reading media must be dissociated from the cognitive and neural effort expended in online information processing while reading from such devices.

    Rehabilitative Ultrasound Imaging (RUSI) must be valuable method for research and rehabilitation. So, the reliability of its measurements must be determined. The purpose of this study was to evaluate the intra-rater reliability of RUSI for measurement of multifidus (MF) muscles cross section areas (CSAs), bladder wall diameter, and thickness of MF muscles between 2 sessions in healthy subjects. Fifteen healthy subjects through simple non-probability sampling participated in this single-group repeated-measures reliability study. MF muscles thickness at rest and during contraction, MF muscles CSAs at rest, and bladder diameters at rest and during pelvic floor muscles (PFM) contraction were measured through RUSI. Pearson's correlation coefficient test was used to determine intra-rater reliability of variables. The results showed that intra-class correlation Coefficient (ICCs) values with 95% confidence interval (CI) and the standard error of the measurement (SEM) were good to excellent agreement for a single investigator between measurement occasions. The intra-rater reliability for the bladder wall displacement was high (ICCs for rest and PFM contraction state: 0.96 and 0.95 respectively), for the MF muscles CSAs at the L4 level was good to high (ICCs 0.75 and 0.91 for right (Rt) and left (Lt) side respectively), and for the thickness of MF muscles at two levels, at rest and during two tasks was moderate to high (ICCs: 0.64 to 0.87). The Trans-Abdominal (TA) method of RUSI is a reliable method to quantify the PFM contraction in healthy subjects. Also, the RUSI is a reliable method to measure the MF muscles CSAs, the MF muscles thickness at rest and during functional tasks in healthy subjects.

    Full Text Available Adipose tissue secretes numerous hormone-like factors, which are known as adipokines. Adipokine receptors have been identified in the central nervous system but the potential role of adipokine signaling in neuroprotection is unclear. The aim of this study is to determine (1 Whether adipokines secreted from cultured adipose tissue of lean humans is protective against oxidative stress-induced neurotoxicity in human SH-SY5Y neuronal cells; and (2 To explore potential signaling pathways involved in these processes. Adipose tissue conditioned media (ATCM from healthy lean subjects completely prevented H2O2 induced neurotoxicity, while this effect is lost after heating ATCM. ATCM activated the phosphorylation of ERK1/2, JNK and Akt at serine 308 in SH-SY5Y cells. PD98059 (25 µM, SP600125 (5 µM and LY29400 (20 µM partially blocked the protective effects of ATCM against H2O2 induced neurotoxicity. Findings demonstrate that heat-sensitive factors secreted from human adipose tissue of lean subjects are protective against H2O2 induced neurotoxicity and ERK1/2, JNK, and PI3K signaling pathways are involved in these processes. In conclusion, this study demonstrates preliminary but encouraging data to further support that adipose tissue secreted factors from lean human subjects might possess neuroprotective properties and unravel the specific roles of ERK1/2, JNK and PI3K in these processes.

  9. The Influence of Surface Tension Gradients on Surfactant Tracer Measurement of Air-Water Interfacial Area in Porous Media

    Air-water interfacial area (AI) in porous media is an important factor governing equilibrium contaminant retention, as well as the kinetics of interphase mass transfer, such as delivery of oxygen to roots and volatilization of methane from landfills. Despite this importance, significant method-dependence is observed among techniques used to determine AI in porous media. In this work, possible low bias in conventional aqueous interfacial-partitioning tracer methodology (IPT) was examined by comparison of IPT-AI estimates with more direct estimates obtained using synchrotron X-ray microtomographic (µCT) imaging. Sodium dodecyl benzene sulfonate and pentafluorobenzoate were used as interfacial and nonreactive tracers, respectively, to measure AI at three water saturations (Sw) in a natural fine sand. IPT-AI exhibited expected trends, with higher areas associated with drier conditions, but the magnitude of AI was as much as 50% lower than those measured by µCT. IPT-AI values for the driest system agreed most closely with microtomography data. Real-time system mass measurements revealed that upon introduction of the surfactant tracer, system Sw decreased by 15-30%; the driest system exhibited the least drainage. This drainage is consistent with a reduction in capillarity caused by the lower surface tension of the surfactant solution as compared to the surfactant-free resident fluid. Drainage in the direction of flow would lead to earlier breakthrough of the surfactant tracer and a lower AI-estimate. In fact, the magnitude of drainage and magnitude of AI-underestimation relative to µCT were qualitatively correlated. Although this effect was expected, its magnitude and potential influence on AI was previously unknown and was larger than anticipated.

    We have developed a new approach for generating pore throat cross sections of various shapes based on distributions of shape factors and radii of inscribed circles. These distributions are obtained from analysis of grains packing. General formulas for calculating geometrical properties and entry capillary pressure for given shape factor and inscribed circle radius are developed. These relationships are employed in a pore network, which has a number of special features. In particular, it is highly flexible in terms of location of pore bodies, variable coordination number, as well as variable cross-sectional shapes. The pore network model is employed for simulating the equilibrium distribution of two fluids in a granular porous medium, under both drainage and imbibition conditions. The pore network model is verified by comparing simulation results with experimental data of quasi-static drainage and imbibition experiments in a glass bead medium. The pore-level topology and geometrical description of pore bodies and pore throats, essential for building the network, are rigorously extracted from experimental data using image analysis (3DMA-Rock software). Calculated capillary pressure-saturation (Pc - Sw) and specific interfacial area-saturation (anw - Sw) curves show very good agreement with measured ones, for both drainage and imbibition. We show that the shape factor can significantly influence the form of macroscopic Pc - Sw and anw - Sw curves, if the length and volumes associated to the pore throats are considerable. Furthermore, using continuous generation of shape factor distribution, the model can be validated against the grain size distribution. After validating the model against experiments, in addition to primary and main curves, we simulate many scanning curves to generate Pc - Sw - anw surfaces for drainage and imbibition, separately. Results show that these two surfaces lie very close to each other, and the average normalized difference is small, in the

    The area (A) under the receiver operating characteristic curve is commonly used to quantify the ability of a biomarker to correctly classify individuals into two populations. However, many markers are subject to measurement error, which must be accounted for to prevent understating their effectiveness. In this paper, we develop a new confidence interval procedure for A which is adjusted for measurement error using either external or internal replicated measurements. Based on the observation that A is a function of normal means and variances, we develop the procedure by recovering variance estimates needed from confidence limits for normal means and variances. Simulation results show that the procedure performs better than the previous ones based on the delta-method in terms of coverage percentage, balance of tail errors and interval width. Two examples are presented. Copyright © 2010 John Wiley & Sons, Ltd.

    This exploratory phenomenological case study investigated the influence the full integration of the arts into core subject instruction has on classroom environment, student academic achievement, and student engagement as perceived by administrators, teachers, and students in one East Texas secondary school. Participant interviews were analyzed using Creswell's (2012) six-step method for analyzing phenomenological studies. The researcher implemented three learning activities in which ceramics learning objectives were fully integrated with chemistry learning objectives. The first activity combined clay properties and pottery wheel throwing with significant numbers. The second activity combined glaze formulation with moles. The third combined stoichiometry with the increased glaze formula for students to glaze the bowls they made. Findings suggest the full integration of art in core subject area instruction has numerous positive effects. Participants reported improved academic achievement for all students including reluctant learners. Students, teachers, and the administrator reported greater participation in the art integrated activities. Participants perceived a need for further training for teachers and administrators for greater success.

    Full Text Available Petunia grandiflora Juss. and Nicotiana alata Link & Otto are two of the most widely spread plants on the market for annual potted ornamental plants. In order to identify the most adequate substrate formula we analyzed the effects of different potting growing media used for P. hybrida grandiflora 'Bravo' and N. alata 'Dinamo' on their photosynthetic capacity, leaf area, and flowering potential. Optimization of growing media formula for petunia and ornamental tobacco was performed by preparing four growing media mixing fallow soil (FS, Biolan peat (BP, acid peat (AP, leaf compost (C, and perlite (P in different proportions. The physiological potential of petunia and ornamental tobacco was investigated by photosynthesis and respiration rate and chlorophyll pigments in leaves, while the vegetative and flowering phenological stages were evaluated by number of leaves per plant, leaf area, number of flowers per plant and leaf area/flowers ratio. These measurements were significantly influenced by the different potting growing media used in this study. In the flowering stage, the highest photosynthesis rates (8.612 μmol CO2 m-2 s-1 as well as leaf area (1.766 dm² of petunias were obtained on growing media with 60% biolan peat, 30% acid peat and 10% perlite (BP60-AP30-P10. Flowering responses to growing conditions vary greatly among plants and the biggest number of ornamental tobacco flowers (22 flowers plant-1 was registered as an effect of BP60-AP30-P10 media. Growing media with the BP60-AP30-P10 formula seem to be the most adequate growth substrate to develop profitable crops for petunias and ornamental tobacco with high decorative value.

    Full Text Available Introduction & Objective: The diagnostic value of endoscopic and microscopic procedures for viewing different structures of middle ear has been widely assessed however, no published study is available for comparing the diagnostic value of them in chronic otitis media patients. The present study conducted to compare diagnostic value of these two procedures for as-sessment of middle ear normal structures and possible defects in these patients. Materials & Methods: In a prospective descriptive analytical study, fifty eight consecutive pa-tients older than 15 years who suffered from chronic otitis media and were candidates for tympanoplasty with or without mastoidectomy were included into the study and underwent operation. After entering the middle ear by post auricular incision and elevation of a tym-panomeatal flap, and prior to surgery , the middle ear was first examined by an operating mi-croscope in different bed and microscope positions and by performing gentle maneuvers on the head and then was reevaluated using a rigid 0 & 30 degree sinoscope. The visible areas of middle ear were separately noted. Results: Structures of epitympanum, posterior mesotympanum, and hypotympanum structures were more visible using endoscope compared with microscope(P0.05. Conclusion: Endoscopic and microscopic procedures had similar diagnostic values to view ossicular chain mobility and reflexes of round window as well as to detect ossicular chain erosions, but different anatomical parts and more hidden pits of the middle ear such as epitympanum, posterior mesotympanum, and hypotympanum are more visible by an endoscopic tool.In case of pathologic conditions, endoscopic approach is recommended for better observation and adequate evaluation of the location before and after the removal of the lesion.

    Carotid intima-media thickness (CIMT) is frequently utilized for detection of subclinical atherosclerosis. This study aims to investigate the association between the CIMT values and demographic characteristics, cardiovascular disease (CVD) risk factors, lipid biochemistry profiles, and high-sensitivity C-reactive protein (hs-CRP) levels among the Indonesian population. Subjects who had two or more CVD risk factors but were not receiving lipid-lowering therapy were recruited from six hospitals of Indonesia. Measurements of CIMT are obtained by ultrasonography of 12 sites within the common carotid artery. CVD risk factors, lipid and glucose profiles, and hs-CRP values were analyzed with respect to distribution of CIMT. The mean-max CIMT was 0.805 ± 0.190 mm (minimum, 0.268 mm; maximum, 1.652 mm) and the mean-mean CIMT was 0.614 ± 0.190 mm (minimum, 0.127 mm; maximum, 1.388 mm). Multivariate analyses confirmed an independent association between increasing CIMT and increasing age (regression coefficient = 0.004; p = 0.004). Our data show normative mean-mean CIMT data for Indonesian subjects with two or more CVD risk factors who are not receiving lipid-lowering therapy, which may guide CVD risk stratification of asymptomatic individuals in Indonesia.

  19. The response of teachers to new subject areas in a national science curriculum: The case of the earth science component

    King, Chris

    2001-11-01

    The National Curriculum for Science (NCS) introduced to schools in England and Wales in 1989 contained an earth science component that was new to many secondary science teachers. Ten years after this introduction, a survey was undertaken to test teacher perception of the effectiveness of their teaching in this subject area that was new to them, and to identify factors that might affect this effectiveness. The information gained has been used in reviewing possible curriculum changes and in developing professional development strategies that would improve the effectiveness of NCS earth science teaching. The data collected from science teachers who are currently teaching this earth science component revealed that their background knowledge of earth science from their own education was generally poor, even though most of them considered their knowledge to be moderate. The teachers indicated that the achievement of their pupils in earth science is moderate, while reports on national testing show it is poor. They reported that their main sources of earth science knowledge and understanding were science textbooks written for 11- to 16-year-old pupils (with their small earth science content of variable quality) and science colleagues (who often have poor earth science backgrounds too). Most teachers indicated that they needed more support in this area. Overall, the data indicated that while teachers consider their teaching in this area to be moderate, other evidence suggests it is poor. If this situation is not to continue it should be addressed. In the longer term the emphasis on the earth science content of the National Science Curriculum could be changed (either enhanced or reduced) within larger scale curriculum changes. Until such curriculum change takes place, effective methods of professional development should be instituted so that teachers have a much improved basis on which to build their earth science teaching. Similar measures would be necessary in other

    The past application of nuclear technology has brought about free emission of numerous Due to the military application of the depleted uranium (DU) in our country, the problem of its radioactivity and hemo toxicity if actualized. Likewise every heavy metal, its is highly toxic and, in addition to it, also radioactive: Interaction of the water-soluble uranium forms with soil is an important effect. In this way, it penetrates into food chain and endangers human health. The study was aimed at determining possible karyotype genotoxic effects in individuals from the regions close to the contaminated areas. Biological dosimetry was performed using modified Moorthead's micromethod. Our studies included the targeted group of 29 patients from the affected regions. The subjects were averagely aged 39.5{+-}2.8 years. Average age of the control group (k), unexposed to the effects of the known genotoxic agents comprising 22 individuals was 28.3{+-}1.2 years. The presented data evidenced that increased incidence of the chromosomal aberrations was found in 6 subjects,accounting for 20.6%. Dicentric type changes were evidence, as well ring chromosomes and eccentric fragments, which are, at the same time the most frequent aberrations. The changes are considered reparable aberrations accounting for 2-3% in metaphases of the unexposed individuals. Statistical data processing evidenced significant difference (p<0.005) between structural chromosomal aberrations in the studied and control groups, as well as in the number of chromatid aberrations (p<0.05).Based on the obtained data it may be concluded that human karyotype changes were present in the studied group, resulting from interaction of ionizing irradiation and other genotoxic agents, with possibility of potent synergistic effects. It is necessary to stress the importance of further monitoring and control of the general population health, particularly due to possible late genetic effects that may affect future generations

    Full Text Available Long term exposure to trace metals in various media is of great concern for people living in known pollution sources, such as mining and industrial activities. Health risk assessment and human hair analysis can provide important information for local environmental management. Information on distribution characteristics of trace metals in soil, water, sediment, air, local crops, and human hair from a typical mining area in southern China was collected. Results show there exists severely trace metal contamination in soil, sediment, and air. Arsenic and Pb contents in the local children’s hair are higher than the upper reference values, and the accumulation of residents’ hair trace metals shows great correlation with the ingestion and inhalation pathways. Arsenic contributes 52.27% and 58.51% to the total non-cancer risk of adults and children, respectively. The cancer risk of Cd in adults and children are 4.66 and 3.22 times higher than the safe level, respectively. Ingestion exposure pathway of trace metals largely contributes to the total non-cancer and cancer effect. The metals As, Cd, and Pb are major risk sources and pollutants that should be given priority for management, and ingestion pathway exposure to trace metals through soil and crops should be controlled.

    The study's overall objective was to investigate the relationship between psychosocial stressors, sense of community, and subjective wellbeing in urban and rural schoolchildren in Northeast Brazil, focusing on differences according to territorial context. The sample consisted of 757 participants, 495 from urban schools and 262 from rural schools, enrolled in the 6th and 7th grades (9 to 18 years of age) in 21 municipal and state public schools, of which 13 urban and 8 rural, in 7 municipalities (counties) in Ceará State, Brazil. The study instruments were inventory of stressful events, scale of life satisfaction for students, index of sense of community, and satisfaction indices by life domains (family, material goods, relations, neighborhood/zone, health, time, school, and personal). The results indicate that socioeconomically underprivileged public schoolchildren from urban areas are more exposed to daily stress and score lower on satisfaction in specific domains of life and on sense of community. This latter is an important indicator for evaluating wellbeing in this young population.

    Macrophages play a major role in the development of vascular lesions in atherogenesis. The cells express FcγRIIIa (CD16) identical to that in NK cells, but with a cell type-specific glycosylation, and these soluble forms (sFcγRIIIa) are present in plasma. We measured sFcγRIIIaMφ derived from macrophages in plasma from subjects undergoing an annual medical checkup. The levels of sFcγRIIIaMφ increased with age, and correlated positively with body mass index, blood pressure, LDL cholesterol to HDL cholesterol ratio, triglycerides, hemoglobin A1c, and creatinine, but negatively with HDL-cholesterol levels. The sFcγRIIIaMφ levels were related to the number of risk factors for atherosclerosis: such as aging, current smoking, diabetes, hypertension, hyper-LDL-cholesterolemia, hypo-HDL-cholesterolemia, and family history of atherosclerotic diseases. In addition, the sFcγRIIIaMφ levels were correlated with carotid maximum intima-media thickness (IMT). These findings indicate the macrophages are activated during the incipient stage of atherosclerosis, and suggest sFcγRIIIaMφ may be used as a predictive marker for atherosclerosis. PMID:18475309

    To assess the prevalence of left ventricular hypertrophy according to electrocardiographic and echocardiographic criteria among hypertensive patients living in semi-rural Senegalese area. According to the World Health Organization STEPSwise approach, we conducted, in November 2012, a cross-sectional and exhaustive study in the population aged at least 35 years old and living for at least six months in the semi-rural area of Guéoul. We researched electrocardiographic and echocardiographic left ventricular hypertrophy in hypertensive subjects. Data were analyzed with SPSS 18.0 software version. The significance level was agreed for a value of P<0.05. We examined 1411 subjects aged on average of 48.5±12.7 years. In total, 654 subjects were hypertensive and screening of left ventricular hypertrophy (LVH) was effective in 515 of them. According to Sokolow-Lyon index, 86 subjects (16.7%) presented electrocardiographic LVH, more frequently in men (P=0.002). According to Cornell index and Cornell product, LVH was founded respectively in 66 (12.8%) and 52 subjects (10.1%), more frequently in female (P=0.0001; P=0.004). It was more common in grade 3 of hypertension however criteria. In echocardiography, prevalence of LVH was 2.2% (13 cases) according to the left ventricular mass, 9.3% (48 cases) according to the left ventricular mass indexed to body surface area and 8.2% (42 cases) according to the left ventricular mass indexed to height 2.7 . LVH was significantly correlated with the electrocardiographic LVH according to Sokolow-Lyon index (P<0.0001) and the grade 3 of hypertension (P=0.003). Although rare in hypertensive Senegalese living in semi-rural area, left ventricular hypertrophy is correlated with severity of grade of hypertension. Screening by electrocardiogram will allow better follow-up of these hypertensive subjects. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  1. The perceptions of teachers and principals toward providing additional compensation to teachers in high-need subject areas

    Science.gov (United States)

    Longing, Jeffrey Lucian

    The purpose of this study was to determine possible differences in the perceptions of teachers teaching in high-need areas (i.e., math, science, special education, etc.) and teachers not teaching in high-need areas, (i.e., business education, physical education, etc.) as defined by the states of Arkansas and Louisiana, regarding higher compensation for high-need teachers. In addition, possible perception differences among principals and teachers were determined. The independent variables consisted of gender, position held, years of certified experience, and certification areas. The dependent variable was the perceptions of the participants on providing higher compensation for high-need teachers in order to attract and retain them. The data for all variables were collected using the Teacher Compensation Survey. The sample for this study was limited to teachers, grades 9 through 12, and principals of public high schools in south Arkansas and north Louisiana. Forty-four school districts in south Arkansas (Arkansas Department of Education, 2008a) and north Louisiana (Louisiana Department of Education, 2008a) met the criteria for this study. Twenty-two superintendents gave permission for their districts to participate in the research. A sample of 849 teachers and 38 principals were identified in these districts. Surveys were returned from 350 teachers, creating a 41% response rate. When the 31 principals that returned surveys were added to the total population, the response rate increased to 43% with 381 of the 887 surveyed responding. However, 42 of the teachers and two of the principals skipped some of the questions on the survey and were not included in the study. The researcher used a One-Way ANOVA and independent t-tests to determine the presence of statistical differences at the .05 level. The data showed that most math and science teachers agreed that high-need teachers should be compensated at a higher rate than teachers not teaching in high-need areas. The data

    Wilson, P B

    2013-10-01

    Psoriasis is associated with serious comorbidities such as cardiovascular disease, type 2 diabetes, and metabolic syndrome. These comorbidities are related to low physical activity in the general population. Limited research has evaluated physical activity in psoriasis, and thus, the purpose of this investigation was to compare physical activity between individuals with and without psoriasis as well as explore the associations between measures of psoriasis severity and physical activity. Cross-sectional study using data from the 2003-2006 National Health and Nutrition Examination Survey. Self-reported psoriasis diagnosis and psoriasis severity were regressed on moderate/vigorous physical activity, as measured objectively by accelerometers. Measures of psoriasis severity included rating of psoriasis as a problem in life and body surface area involvement. A total of 4316 individuals had data on psoriasis, moderate/vigorous physical activity, and relevant covariates, with 3.6% (population weighted) of participants (N.=117) reporting a diagnosis of psoriasis. A psoriasis diagnosis was not associated with moderate/vigorous physical activity, and furthermore, body surface area involvement was not associated with moderate/vigorous physical activity among participants with psoriasis. However, every tertile increase in psoriasis as a problem in life was associated with 28% less moderate/vigorous physical activity, which remained significant after adjusting for covariates and removing outliers. While a diagnosis of psoriasis and body surface area involvement do not appear to be associated with less moderate/vigorous physical activity, individuals that rate their psoriasis to be a large problem engage in less moderate/vigorous physical activity.

    2014-01-01

    Full Text Available In Brazil, malaria is prevalent in the Amazon region and these regions coincide with high prevalence of intestinal parasites but few studies explore the interaction between malaria and other parasites. Therefore, the present study evaluates changes in cytokine, chemokine, C-reactive protein, and nitric oxide (NO concentrations in 264 individuals, comparing plasma from infected individuals with concurrent malaria and intestinal parasites to individuals with either malaria infection alone and uninfected. In the studied population 24% of the individuals were infected with Plasmodium and 18% coinfected with intestinal parasites. Protozoan parasites comprised the bulk of the intestinal parasites infections and subjects infected with intestinal parasites were more likely to have malaria. The use of principal component analysis and cluster analysis associated increased levels of IL-6, TNF-α, IL-10, and CRP and low levels of IL-17A predominantly with individuals with malaria alone and coinfected individuals. In contrast, low levels of almost all inflammatory mediators were associated predominantly with individuals uninfected while increased levels of IL-17A were associated predominantly with individuals with intestinal parasites only. In conclusion, our data suggest that, in our population, the infection with intestinal parasites (mainly protozoan does not modify the pattern of cytokine production in individuals infected with P. falciparum and P. vivax.

  4. Changes in the distribution of red foxes (Vulpes vulpes in urban areas in Great Britain: findings and limitations of a media-driven nationwide survey.

    Directory of Open Access Journals (Sweden)

    Dawn M Scott

    Full Text Available Urbanization is one of the major forms of habitat alteration occurring at the present time. Although this is typically deleterious to biodiversity, some species flourish within these human-modified landscapes, potentially leading to negative and/or positive interactions between people and wildlife. Hence, up-to-date assessment of urban wildlife populations is important for developing appropriate management strategies. Surveying urban wildlife is limited by land partition and private ownership, rendering many common survey techniques difficult. Garnering public involvement is one solution, but this method is constrained by the inherent biases of non-standardised survey effort associated with voluntary participation. We used a television-led media approach to solicit national participation in an online sightings survey to investigate changes in the distribution of urban foxes in Great Britain and to explore relationships between urban features and fox occurrence and sightings density. Our results show that media-based approaches can generate a large national database on the current distribution of a recognisable species. Fox distribution in England and Wales has changed markedly within the last 25 years, with sightings submitted from 91% of urban areas previously predicted to support few or no foxes. Data were highly skewed with 90% of urban areas having <30 fox sightings per 1000 people km(-2. The extent of total urban area was the only variable with a significant impact on both fox occurrence and sightings density in urban areas; longitude and percentage of public green urban space were respectively, significantly positively and negatively associated with sightings density only. Latitude, and distance to nearest neighbouring conurbation had no impact on either occurrence or sightings density. Given the limitations associated with this method, further investigations are needed to determine the association between sightings density and actual fox

It addressed the ways in which young women tactically use the social media in order to negotiate the sexual controls they encountered in everyday life. Taking the teenage girls' point of view, this paper argues that, as active agents, young women achieve a certain level of sexual autonomy and construct their own sexual selves in modern northern Thai society, despite their parents' attempts to prevent this. The paper highlights the ways in which social media are used by Thai girls in order to achieve such a goal. Research findings should inform the development of future programmes on sexual health promotion, parental skills and sexual communication between Thai parents and their children.

    A theoretical model for calculating spontaneous and stimulated Brillouin scattering(SBS) spectra is described. An empirical formula for the Stokes output spectral linewidth, a function of spontaneous Brillouin linewidth and the exponential gain coefficient, is obtained by the calculated data fitting. The formula holds true for two cases involving pump undepletion and depletion. The lineshape change from spontaneous to highly pump-depleted SBS spectra is also investigated. The result shows that for the pump power below the SBS threshold, the Stokes output spectral lineshape evolves from Lorentzian to approximately Gaussian as the pump power increases. For the pump power near or beyond the threshold, the SBS spectrum is in the form of a steady Gaussian profile, and the spectral linewidth comes to a certain value about 7 times narrower than the spontaneous one. The theoretical results are experimentally demonstrated by using several common liquid media.

    [Purpose] This study investigated whether the toe-spread-out exercise affects the hallux valgus angle, the cross-sectional area of the abductor hallucis muscle, and the hallux valgus angle during active abduction. [Subjects and Methods] Twenty-four subjects with hallux valgus were randomly assigned to orthosis and orthosis plus toe-spread-out exercise groups. The orthosis group wore the orthosis for 8 weeks, while the orthosis plus toe-spread-out group also performed the toe-spread-out exercise. The hallux valgus angle, the cross-sectional area of the abductor hallucis muscle, and the hallux valgus angle during active abduction were measured initially and after 8 weeks by radiography and ultrasonography. [Results] While there were no significant changes in the three parameters in the orthosis group, there were significant differences in the orthosis plus toe-spread-out exercise group after 8 weeks. In addition there were significant differences in the three measures between the two groups. [Conclusion] The toe-spread-out exercise reduces the hallux valgus angle and hallux valgus angle during active abduction, and increases the cross-sectional area of the abductor hallucis muscle. The toe-spread-out exercise is recommended for patients with mild to moderate hallux valgus.

    Full Text Available Maria Bell, Jan Douglas, Christopher CuttsCentre for Pharmacy Postgraduate Education, Manchester Pharmacy School, University of Manchester, Manchester, UKAbstract: Social media is progressively being used for sharing health information and for networking among health professionals and patients; this is particularly evident among the younger age groups. There is great potential for pharmacy to engage in the utilization of such platforms to improve health outcomes, and this paper explores some of the areas where social media is already in use in pharmacy and potential areas where using social media could make a positive impact on the determinants of health. The literature around this subject is limited; nevertheless, the number of published studies has increased in recent years. This paper concentrates on the use and application of social media by pharmacy to improve health outcomes. The subject was explored in five main areas: provision of medicines information, safer use of medicines, medicines use in chronic disease, implementation of evidence-based medicine and guidelines, and finally clinical research. In each of these areas, there is an increase in uptake and use of social media platforms by pharmacists and other health care professionals to improve patient outcomes. A variety of the more popular social media platforms have been used by health care professionals and the relative merits of these are discussed within each of the subject areas and consideration given to their application in pharmacy practice. It is evident that the majority of social media users fall into the younger age bracket, which is understandable. However, the majority of patients living with long-term conditions typically fall into the older age bracket (over 65 years of age and this should be taken into account when utilizing social media platforms to improve health outcomes.Keywords: social media, pharmacy, outcomes, impact, health

    Previous analyses concerning health components of European Union (EU)-funded research have shown low project participation levels of the 12 newest member states (EU-12). Additionally, there has been a lack of subject-area analysis. In the Health Research for Europe project, we screened all projects of the EU's Framework Programmes for research FP5 and FP6 (1998-2006) to identify health research projects and describe participation by country and subject area. FP5 and FP6 project databases were acquired and screened by coders to identify health-related projects, which were then categorized according to the 47 divisions of the EU Health Portal (N = 2728 projects) plus an extra group of 'basic/biotech' projects (N = 1743). Country participation and coordination rates for projects were also analyzed. Approximately 20% of the 26 946 projects (value €29.2bn) were health-related (N = 4756. Value €6.04bn). Within the health categories, the largest expenditures were cancer (11.9%), 'other' (i.e. not mental health or cardiovascular) non-communicable diseases (9.5%) and food safety (9.4%). One hundred thirty-two countries participated in these projects. Of the 27 EU countries (and five partner countries), north-western and Nordic states acquired more projects per capita. The UK led coordination with > 20% of projects. EU-12 countries were generally under-represented for participation and coordination. Combining our findings with the associated literature, we comment on drivers determining distribution of participation and funds across countries and subject areas. Additionally, we discuss changes needed in the core EU projects database to provide greater transparency, data exploitation and return on investment in health research. © The Author 2013.

  12. Modeling of Multi Phase Flow in Porous Media: Operator Splitting, Front Tracking, Interfacial Area and Network Models

    Energy Technology Data Exchange (ETDEWEB)

    Nordhaug, Hans Fredrik

    2001-07-01

    In reservoir problems we consider some or all of the following phases: Oil, gas, water and solid. The solid phase is normally assumed to be immobile and non-deforming, but in general this does not need to be the case. By multi phase flow we will mean the flow of oil, gas and water. The phases are categorized according to their different physical quantities. A hydrocarbon phase, may consist of different hydrocarbon components, e.g., the oil phase can contain several oil and gas types. In this work the components are neglected and only the phases are considered. A porous medium is any solid phase, e.g. sand stone, that is permeable. The flow in a porous medium takes place through connected pores in the rock. Regions on a larger scale that contain oil or gas are called reservoirs. The typical size of a reservoir is kilometers in each direction while the pore scale size is millimeters or less. Solving the Navier-Stokes equation at the pore scale to obtain the transport on a larger scale is not numerically feasible because of the huge difference in scales. Therefore, some averaging is necessary to go from the pore scale (micro scale) to the reservoir scale (macro scale). In this process the Navier-Stokes equations are replaced by macro scale equations that are solved for macro scale variables. The papers presented herein cover several topics in multi phase flow in porous media, and they address some central problems both on the micro scale as well as on the macro scale. In addition, operator splitting techniques have been developed for convection dominated non-linear transport equations.

    Full Text Available This paper presents the results of a qualitative research that explores, from an intergenerational and gender perspective, how the use of audiovisual media influences to personal well-being in adolescence. Three, semi-structured group interviews were used with adolescent girls (aged 12 to 18 years, and two with mothers of boys and girls of those ages. The results show that interpersonal relationships are one of the factors that greatly contribute to the adolescents’ well-being. Girls said that the use of technology generates personal well-being because it allows them to maintain interpersonal relationships with their peers. The mothers, however, question whether overuse of technology can contribute to their personal well-being. On the other hand, girls and mothers agree to comment that the use of technology hinders the relationships that adolescents have with their parents.

    The purpose of this study was to identify nicotine dependence, smoking-related attitude, and subjective norms across the stages of change for smoking cessation among adult smokers in a rural area. The subjects were 276 current smokers (male=243, female=33). There were 3 stages of change for smoking cessation: pre-contemplation, contemplation, and preparation stage. Data was collected by an interview or self-reporting from February 12th to March 5th 2004, and analyzed with frequency, percentage, chi- square-test, Fisher's exact probability test, ANOVA, and Scheffe test using the SPSS-PC program. According to the stages of change, 114(41.3%) current smokers were in pre-contemplation, 110(39.9%) in contemplation, and 52(18.8%) in the preparation stage. There was a higher percentage of males than females (chi- square=8.99, p=.011) in the preparation stage. The mean score of the smoking-related attitude (F=7.43, p=.001) and subjective norm(F=27.41, p=.001) were both lowest in the pre-contemplation stage and increased positively during the stages of change for smoking cessation. Based on these findings, the authors recommend that community-based smoking cessation programs should be developed by considering the intention or motives of current smokers and should be initiated in the preparation stage and primarily for male groups.

    Polychlorinated biphenyls (PCBs) are banned worldwide under the Stockholm Convention on Persistent Organic Pollutants. However, PCBs are still emitted in appreciable amounts from remaining primary sources in urban areas or landfills and are ubiquitous environmental contaminants, inter alia in soil and air. Concentrations of PCBs have been measured in various media by numerous studies worldwide. However, monitoring data do not always provide quantitative information about transport processes between different media, deposition fluxes to ground, or distribution of PCBs between environmental compartments. Also future trends in environmental contamination by PCBs cannot be predicted from monitoring data, but such information is highly relevant for decision-makers. Here, we present a new regionally resolved dynamic multimedia mass balance model for Switzerland to investigate the origin of PCBs in air and to investigate their long-term fate and mass balance in the environment. The model was validated with existing field data for PCBs. We find that advective inflow of PCBs from outside Switzerland into the atmospheric boundary layer is responsible for 80% of PCBs present in air in Switzerland, whereas Swiss emissions cause the remaining 20%. Furthermore, we show that the atmospheric deposition of the higher-chlorinated PCBs is dominated by particle-bound deposition, whereas the deposition of the lower-chlorinated PCBs is a combination of particle-bound and gaseous deposition. The volume fraction of particles in air is in both cases an important factor driving the deposition of PCBs to ground and, thus, contributing to the higher concentrations of PCBs generally observed in populated and polluted areas. Regional emissions influence the deposition fluxes only to a limited extent. We also find that secondary emissions from environmental reservoirs do not exceed primary emissions for all PCB congeners until at least 2036. Finally, we use our model to evaluate the effect of

    Epidemiological studies have analyzed the association between carotid intima-media thickness (CIMT) and insulin resistance, glucose levels or glycated hemoglobin with mixed results. We aimed to evaluate the association between CIMT and homeostasis model assessment - insulin resistance (HOMA-IR), fasting and post-load plasma glucose and glycated hemoglobin in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline. We included 8028 participants (aged 35-74 years) without diabetes or overt cardiovascular disease who had complete CIMT data at baseline. We built crude and adjusted linear and binary logistic models to evaluate the association between CIMT and (a) HOMA-IR; (b) fasting plasma glucose; (c) post-load plasma glucose; and (d) glycated hemoglobin. We also built post-hoc models, stratified by sex. In the fully-adjusted linear models, only the association between CIMT (in mm) and HOMA-IR remained significant (β = 0.004; 95% confidence interval [95%CI]:0.001 to 0.006). Consistent with these results, only the association between the highest age- sex- and race-specific CIMT quartile and HOMA-IR was significant in the adjusted logistic model (odds ratio [OR]:1.10; 95% CI:1.04-1.17). The association between HOMA-IR and the highest CIMT quartile remained significant in sex-specific analyses (OR:1.10; 95% CI:1.02-1.20 for men and OR:1.10; 95% CI:1.02-1.20 for women). We did not find an independent association between CIMT and glucose or glycated hemoglobin. We found a direct association between HOMA-IR and CIMT in a large sample of non-diabetic participants. Mechanisms unrelated to glucose homeostasis, as a direct effect of insulin on atherosclerosis, or medial hypertrophy, may be involved. Copyright © 2017 Elsevier B.V. All rights reserved.

  20. Using Social Media to Measure the Contribution of Red List Species to the Nature-Based Tourism Potential of African Protected Areas.

    Full Text Available Cultural ecosystem services are defined by people's perception of the environment, which make them hard to quantify systematically. Methods to describe cultural benefits from ecosystems typically include resource-demanding survey techniques, which are not suitable to assess cultural ecosystem services for large areas. In this paper we explore a method to quantify cultural benefits through the enjoyment of natured-based tourism, by assessing the potential tourism attractiveness of species for each protected area in Africa using the IUCN's Red List of Threatened Species. We use the number of pictures of wildlife posted on a photo sharing website as a proxy for charisma, popularity, and ease of observation, as these factors combined are assumed to determine how attractive species are for the global wildlife tourist. Based on photo counts of 2473 African animals and plants, species that seem most attractive to nature-based tourism are the Lion, African Elephant and Leopard. Combining the photo counts with species range data, African protected areas with the highest potential to attract wildlife tourists based on attractive species occurrence were Samburu National Reserve in Kenya, Mukogodo Forest Reserve located just north of Mount Kenya, and Addo Elephant National Park in South-Africa. The proposed method requires only three data sources which are freely accessible and available online, which could make the proposed index tractable for large scale quantitative ecosystem service assessments. The index directly links species presence to the tourism potential of protected areas, making the connection between nature and human benefits explicit, but excludes other important contributing factors for tourism, such as accessibility and safety. This social media based index provides a broad understanding of those species that are popular globally; in many cases these are not the species of highest conservation concern.

    Full Text Available There is increasing evidence of large carnivore presence outside protected areas, globally. Although this spells conservation success through population recoveries, it makes carnivore persistence in human-use landscapes tenuous. The widespread distribution of leopards in certain regions of India typifies this problem. We obtained information on leopard-human interactions at a regional scale in Karnataka State, India, based on systematic surveys of local media reports. We applied an innovative occupancy modelling approach to map their distribution patterns and identify hotspots of livestock/human depredation. We also evaluated management responses like removals of 'problem' leopards through capture and translocations. Leopards occupied around 84,000 km2 or 47% of the State's geographic area, outside designated national parks and wildlife sanctuaries. Their presence was facilitated by extent of vegetative cover- including irrigated croplands, rocky escarpments, and prey base in the form of feral and free-ranging dogs. Higher probabilities of livestock/human attacks by leopards were associated with similar ecological features as well as with capture/removals of leopards. Of the 56 cases of leopard removals reported, 91% did not involve human attacks, but followed livestock predation or only leopard sightings. The lack of knowledge on leopard ecology in human-use areas has resulted in unscientific interventions, which could aggravate the problem rather than mitigating it. Our results establish the presence of resident, breeding leopards in human-use areas. We therefore propose a shift in management focus, from current reactive practices like removal and translocation of leopards, to proactive measures that ensure safety of human lives and livelihoods.

    The impact of the mass media on woman's status was addressed at two 1995 conferences: the Fourth World Conference on Women, held in Beijing, China, and the Congress of the World Association for Christian Communication, held in Puebla, Mexico. The globalization process facilitated by the mass media has served to increase the power of patriarchy, with no advantages to the cause of women's rights. Coverage of popular movements has been suppressed out of deference to male-controlled governments. Coverage of the Beijing Conference highlighted celebrities and personal stories, to the exclusion of the economic and political issues under debate. Television has commodified women, reinforcing their oppression. On the other hand, the alternative media, which tend to be decentralized, democratic, low-cost, and low in technology, are presenting women as subjects rather than objects and deconstructing gender stereotypes. Of concern, however, is the tendency of computer technology to widen the gap between social classes and developed and developing countries. Women must use information networks to disseminate information on women's rights and strengthen the links between women throughout the world.

    Iodine is an essential microelement required for normal functioning of thyroid gland. Natural deficiency of stable iodine is compensated by its active intake by thyroid and provokes its higher irradiation in case of radiation accidents and contamination of the environment by radioiodine isotopes. The bioavailability of both stable and radioactive iodine and the specificity of its uptake by living organisms largely depends on geochemical parameters of the environment related to natural conditions of water migration. The goal of the study was to investigate spatial distribution of iodine in natural water of different chemical composition in relation to typical water-bearing soils and rocks and water fractions in Bryansk areas subjected to radioiodine contamination after the Chernobyl accident and to evaluate contribution of this factor to the occurrence of endemic thyroid diseases among local population inhabiting geochemically different areas of fluvioglacial and loess-like sedimentary rocks. The highest content of iodine (Me=13.3 µg/l) was observed in surface water of landscapes with H-Ca, Ca and H-Ca-Fe classes of water migration. The lowest microelement level (Me=5.25 µg/l) was noted in groundwater of landscapes with H, H-Fe classes of water migration in areas of Paleogene water bearing rocks. Regardless of the type of source and class of water migration up to 90% of the total content of iodide is present in the fraction membrane filtration). Up to 50% of iodine pass to solution containing particles water in areas of loess-like sedimentary rocks hosts the highest levels of iodine where its associated with calcium mineral aquatic complexes and the suspended particles. The obtained data is believed to be useful in explanation of mobility and intake of iodine and its radioactive analogues by rural population living in different geochemical conditions and using local drinking waters. The data should be accounted of in planning prophylactics of endemic diseases and

    Full Text Available Programmes of formal education establish a systematic transfer of knowledge as well as universal values from one generation to another. By that, they ensure the survival of social structures, prevent radical disruptions in their continuity, and serve as basis for general development of a society. Their content and didactic arrangements include interweaving of two basic aspects: the cognitive one and the one related to vzgoja (i.e. upbringing, moral/value education etc.. The latter aims to achieve the ideals of a tolerant, just and lifelong learning society, but seems to be facing increasing challenges, mainly emerging from neoliberal capitalist mentality. Art history as a school subject area in elementary and secondary education may provide an insight beneath the surface of historical events. Thus, it helps develop a critical view towards them and consequently towards the present real-life situations, which contributes to ascending the taxonomic scale of conative educational goals.

    Medical and nursing shortages in rural areas represent a current serious public health problem. The healthcare of the rural population is at risk. This study compares perceived workload, job satisfaction and work-life balance of physicians and nurses at a clinic in a rural area with two clinics of a University hospital. Physicians and nurses were interviewed anonymously with a standardized questionnaire (paper and pencil), including questions on job satisfaction, subjective workload and work-life balance. The response rate was almost 50% in the University hospital as well as in the municipal hospital. 32 physicians and 54 nurses from the University hospital and 18 physicians and 137 nurses from the municipal hospital participated in the survey. Nurses at the University hospital assessed the organization of the daily routine with 94.1% as better than those at the municipal hospital (82.4%, p=0.03). Physicians at the University hospital were able to better implement acquired knowledge at a University clinic with 87.5% than their counterparts at the municipal hospital (55.5%, p=0.02). In contrast to their colleagues at the municipal hospital, only 50% of the physicians at the University hospital subjectively considered their workload as just right (83.3% municipal, p=0.02). 96.9% of the physicians at the University hospital were "daily" or "several times a week" under time pressure (municipal 50%, pwork and family life (62.9% University hospital, 72.8% Municipal hospital). In contrast, only 20% of the physicians at the University Hospital but 42.9% of the physicians of the municipal hospital had sufficient opportunities to balance workload and family (p=0.13). The return rate of almost 50% can be described as good. Due to the small number of physicians, especially from the municipal hospital, it can be assumed that some interesting differences could not be detected. There were only slight differences between the nurses from the two hospitals. In contrast, subjective

    In this study, we proposed a Regional Probabilistic Risk Assessment (RPRA) to estimate the health risks of exposing residents to heavy metals in different environmental media and land uses. The mean and ranges of heavy metal concentrations were measured in water, sediments, soil profiles and surface soils under four land uses along the Shunde Waterway, a drinking water supply area in China. Hazard quotients (HQs) were estimated for various exposure routes and heavy metal species. Riverbank vegetable plots and private vegetable plots had 95th percentiles of total HQs greater than 3 and 1, respectively, indicating high risks of cultivation on the flooded riverbank. Vegetable uptake and leaching to groundwater were the two transfer routes of soil metals causing high health risks. Exposure risks during outdoor recreation, farming and swimming along the Shunde Waterway are theoretically safe. Arsenic and cadmium were identified as the priority pollutants that contribute the most risk among the heavy metals. Sensitivity analysis showed that the exposure route, variations in exposure parameters, mobility of heavy metals in soil, and metal concentrations all influenced the risk estimates.

    Full Text Available Antibiotic resistance is an increasingly serious threat to human health that needs an urgent action. The aim of this study was to determine the prevalence and antibiotic susceptibility profiles of bacteria isolated from patient ear discharges suspected of otitis media. A retrospective analysis was performed using culture and antibiotic susceptibility test results of 1225 patients who visited Dessie Regional Health Research Laboratory from 2001 to 2011. Results showed a strong association (P<0.001 between age and the risk of acquiring middle ear infection. The predominant bacterial isolates were Proteus spp. (28.8%, Staphylococcus aureus (23.7%, and Pseudomonas spp. (17.2%. Most of the isolated bacteria showed high resistance to ampicillin (88.5%, ceftriaxone (84.5%, amoxicillin (81.9%, and tetracycline (74.5%. About 72.5% of Proteus spp. and 62.2% of Pseudomonas spp. have developed resistance to one and more antibiotics used to treat them. This retrospective study also revealed the overall antibiotic resistance rate of bacterial isolates was increased nearly twofold (P=0.001 over the last decade. Relatively, ciprofloxacin and gentamicin were the most effective antibiotics against all the isolates. In conclusion, antibiotic-resistant bacteria are alarmingly increasing in Wollo area, northeastern Ethiopia, and becoming a major public health problem in the management of patients with middle ear infection.

  12. Chemical composition of drinking water as a possible environment-specific factor modifying the thyroid risk in the areas subjected to radioiodine contamination

    Water is one of the main natural agents providing chemical elements' migration in the environment and food chains. In our opinion a study of spatial variation of the essential trace elements in local drinking water is worth considering as the factor that may contribute to variation of the health risk in areas contaminated by radionuclides and radioiodine in particular. Radioiodine was proved to increase the risk of thyroid cancer among children who lived in areas contaminated during the Chernobyl accident. It was also shown that low stable iodine status of the contaminated area and population also contributed to the risk of this disease in case of radionuclide contamination. The goal of the study was to investigate chemical composition of the drinking water in rural settlements of the Bryansk oblast' subjected to radioiodine contamination and to evaluate speciation of stable I and Se on the basis of their total concentration and chemical composition of the real water samples with the help of thermodynamic modelling. Water samples were collected from different aquifers discharging at different depths (dug wells, local private bore holes and water pipes) in rural settlements located in areas with contrasting soil iodine status. Thermodynamic modelling was performed using original software (HCh code of Y.Shvarov, Moscow State University, RUSSIA) incorporating the measured pH, Corg and elements' concentration values. Performed modelling showed possibility of formation of complex CaI+ ion in aqueous phase, I sorption by goethite and transfer of Se to solid phase as FeSe in the observed pH-Eh conditions. It helped to identify environmental conditions providing high I and Se mobility and their depletion from natural waters. Both the experimental data and modeling showed that I and Se migration and deficiency in natural water is closely connected to pH, Eh conditions and the concentration of typomorphic chemical elements (Ca, Mg, Fe) defining the class of water migration

    Full Text Available Over the past decade, social media platforms have penetrated deeply into the mech­anics of everyday life, affecting people's informal interactions, as well as institutional structures and professional routines. Far from being neutral platforms for everyone, social media have changed the conditions and rules of social interaction. In this article, we examine the intricate dynamic between social media platforms, mass media, users, and social institutions by calling attention to social media logic—the norms, strategies, mechanisms, and economies—underpin­ning its dynamics. This logic will be considered in light of what has been identified as mass me­dia logic, which has helped spread the media's powerful discourse outside its institutional boundaries. Theorizing social media logic, we identify four grounding principles—programmabil­ity, popularity, connectivity, and datafication—and argue that these principles become increas­ingly entangled with mass media logic. The logic of social media, rooted in these grounding principles and strategies, is gradually invading all areas of public life. Besides print news and broadcasting, it also affects law and order, social activism, politics, and so forth. Therefore, its sustaining logic and widespread dissemination deserve to be scrutinized in detail in order to better understand its impact in various domains. Concentrating on the tactics and strategies at work in social media logic, we reassess the constellation of power relationships in which social practices unfold, raising questions such as: How does social media logic modify or enhance ex­isting mass media logic? And how is this new media logic exported beyond the boundaries of (social or mass media proper? The underlying principles, tactics, and strategies may be relat­ively simple to identify, but it is much harder to map the complex connections between plat­forms that distribute this logic: users that employ them, technologies that

    Full Text Available An objective of the Built Environment and Active Play (BEAP Study was to examine whether home built environment, bedroom electronic presence, parental rules and demographics predicted children's sedentary behavior (SB. In 2014, BEAP Study questionnaires were mailed to 2000 parents of children (7–12 years within the Washington DC area. SB-Duration (hours/day and SB-Frequency (days/week were assessed by two questions with multiple subparts relating to SB activity type (e.g. car riding and SB companionship (e.g. friends. Built environment, bedroom electronic presence, parental rules and demographic data were obtained through questionnaire items and ordered logistic regression models were used to examine whether these variables were associated with SB. Study sample included 144 children (female (50%; average age (9.7 years; White (56.3%; Black/African-American (23.7%; Asian-Americans (10.4%. Nearly 40% of the sample reported daily solitary SB with car riding being the most frequently reported type of SB. Children living on streets without a dead-end/cul-de-sac exhibited a higher odds in SB-Duration using electric media [2.61 (CI: 1.31, 5.18] and having no television in a child's bedroom was associated with a lower odds in SB-Frequency [0.048 (CI: 0.006, 0.393] and SB-Duration [0.085 (CI: 0.018, 0.395]. Non-Hispanic/Latino children were also found to have higher odds in solitary SB-Frequency when parental rules of electronic use were modeled [8.56 (CI: 1.11, 66.01]. Based on results from this cross-sectional study, home neighborhood built environment, bedroom electronic presence and absence of parental rules can significantly predict children's SB.

    The American Academy of Pediatrics recognizes that exposure to mass media (eg, television, movies, video and computer games, the Internet, music lyrics and videos, newspapers, magazines, books, advertising) presents health risks for children and adolescents but can provide benefits as well. Media education has the potential to reduce the harmful effects of media and accentuate the positive effects. By understanding and supporting media education, pediatricians can play an important role in reducing harmful effects of media on children and adolescents.

    We sought to ascertain the changes in mortality from ischaemic heart disease (IHD) from 2004 to 2010 in China as the sheer size of China's population makes disease patterns relevant globally. Data on IHD mortality were obtained from the Chinese Centre for Disease Control and Prevention National Disease Surveillance Point System, which includes 161 counties and a population of over 73 million-a representative sample of over 6% of the entire population of China. Both crude and World Health Organization (WHO)-standardized IHD mortality increased, in both men and women and in both urban and rural locations, during the study period, demonstrating the effect of urbanization, economic growth, and epidemiological transition on cardiovascular health. WHO-standardized IHD mortality increased for rural males by 9.2% per year (95% CI: 6.7-11.7%; P < 0.0001), and the trend was statistically significantly higher (P = 0.0001) than in urban males by 6.4% per year (95% CI: 3-10%; P = 0.02). WHO-standardized IHD mortality rate increased for rural females by 7.0% per year (95% CI: 4.6-9.4%; P < 0.0001); this was statistically significantly higher than urban females by 4.3% per year (95% CI: 1-8%; P = 0.02). The age group over 80 years showed the greatest increase in IHD mortality. Mortality from IHD is increasing in China, in contrast to decreasing in other countries. This is largely driven by increasing IHD mortality in rural areas and subjects over 80 years old. This needs urgent attention by public health workers and policymakers.

    Full Text Available This paper aims to examine how the secular media in Surakarta represent Islam in the case of Charlie Hebdo. Therefore, this study used discourse analysis of Theo van Leeuwen focusing on how the subject or actor of the show in the media. This study concluded that the media represent Islam not only with “Western ideology” through idioms such as radical Islamist militants and terrorists, but also with "Islamic ideology". It is done through the construction of Islam as a religion of moderation and delegitimize Charlie Hebdo as magazine satyr abusing freedom. Various strategies are used ranging from strategy passivation to interdetermination. In this case, there are two poles of attraction in both media, namely the Western and Islamic ideology. If both media are quoting from Western sources, the Western ideology dominates the media narrative. Conversely, when both media used Islamic sources, the influence of Islamic ideology dominates the narrative of both media.

  19. "Honk against homophobia": rethinking relations between media and sexual minorities.

    Venzo, Paul; Hess, Kristy

    2013-01-01

    The theory of "symbolic annihilation" or "symbolic violence" has been used in academic literature to describe the way in which sexual minorities have been ignored, trivialized, or condemned by the media. This article aims to de-center research from issues of media representation to consider the capacity for minority groups to proactively use new media and its various avenues for interactivity, social networking, and feedback to fight social exclusion. This work suggests that new media has become a space in which the nominally marginal in society may acquire "social artillery"-a term used to describe how sexual minorities utilize their expanding and more readily accessible social connections in digital space to combat instances of homophobia. The research draws on the results of an inquiry into the relation between media and a regional youth social justice group in Australia tackling homophobia. The research demonstrates that the group is becoming increasingly adept and comfortable with using a cross-section of media platforms to fulfill their own objectives, rather than seeing themselves as passive subjects of media representation. This article argues that this sets an example for other socially excluded groups looking to renegotiate their relation with the media in regional areas.

  20. Gender Bias in the Media: The Case of Iceland

    Directory of Open Access Journals (Sweden)

    Valgerður Jóhannsdóttir

    2015-12-01

    Full Text Available The news media are the most influential sources of information, ideas and opinion for most people around the world. Who appears in the news and who is left out, what is covered and what is not and how people and events are portrayed matter. Research has consistently shown that women are underrepresented in the news and that gender stereotypes are reinforced in and through the media. The 1995 Beijing Declaration and Platform for Action recognised the relationship between women and media as a major area of concern in achieving gender equality in contemporary societies. This article presents Nordic findings from the 2015 Global Media Monitoring Project (GMMP, which is the largest and longest-running study on gender in the world’s media. The findings show that women account for only 1 in 5 of the people interviewed or reported on by Icelandic news media and that women’s overall presence in the news has declined compared to the last GMMP study in 2010. The proportion of women as news subjects is also considerably lower than in other Nordic countries. We argue that the number of women who are journalists, managers in the media industry and decision makers in society has increased, but this shift has not automatically changed the representation of women in the news, either in numbers or in their portrayal. This discrepancy indicates that the relationship between gender and the news media is complicated and needs to be approached from different perspectives.

    Full Text Available The media play a central role in informing the public about what happens in the world, particularly in those areas in which audiences do not possess direct knowledge or experience. This article examines the impact the media has in the construction of public belief and attitudes and its relationship to social change. Drawing on findings from a range of empirical studies, we look at the impact of media coverage in areas such as disability, climate change and economic development. Findings across these areas show the way in which the media shape public debate in terms of setting agendas and focusing public interest on particular subjects. For example, in our work on disability we showed the relationship between negative media coverage of people on disability benefit and a hardening of attitudes towards them. Further, we found that the media also severely limit the information with which audiences understand these issues and that alternative solutions to political problems are effectively removed from public debate. We found other evidence of the way in which media coverage can operate to limit understanding of possibilities of social change. In our study of news reporting of climate change, we traced the way that the media have constructed uncertainty around the issue and how this has led to disengagement in relation to possible changes in personal behaviours. Finally, we discuss the implications for communications and policy and how both the traditional and new media might help in the development of better informed public debate.

    Full Text Available In Germany, educational standards for key school subjects have been developed as a consequence of the results of international comparative studies like PISA. Subsequently, supporters of interdisciplinary fields such as media education have also started calling for goals in the form of competency models and standards. In this context a competency standard model for media education will be developed with regard to the discussion about media competence and media education. In doing so the development of a competency model and the formulation of standards is described consequently as a decision making process. In this process decisions have to be made on competence areas and competence aspects to structure the model, on criteria to differentiate certain levels of competence, on the number of competence levels, on the abstraction level of standard formulations and on the tasks to test the standards. It is shown that the discussion on media education as well as on competencies and standards provides different possibilities of structuring, emphasizing and designing a competence standard model. Against this background we describe and give reasons for our decisions and our competency standards model. At the same time our contribution is meant to initiate further developments, testing and discussion.

    Full Text Available ABSTRACT Media Entrepreneurship has been an ambiguous, unclear and controversial concept and despite of growing academic efforts in the last decade, it is still a poorly defined subject. This paper is an effort to fill this gap by providing a comprehensive definition of media entrepreneurship. Firstly, a literature review conducted and entrepreneurship, media, opportunity and innovation as building blocks of media entrepreneurship explained. Then by using of a mixed of bibliographic method and a Delphi method with multi-stage analysis process, a consensual definition of media entrepreneurship proposed. This definition integrates some key features of the emerging media environment such as distinction of content and platform, value delivery, opportunity development, non-monetary benefit, etc. It is expected that the findings of this research clear the ground for further researches in the field of media entrepreneurship.

    Full Text Available Few countries in the world have introduced media education into their curriculums. Montenegro became one of them in 2009, when “media literacy” was introduced as an optional subject for 16 and 17 year old students of Gymnasium high schools. This article presents the findings of the first and only research conducted so far on media education in Montenegro. It is a national case study which examines the potential of media education to change the school culture and accelerate education system reform towards embracing the new digital education paradigm in the future. The focus is on the results of research conducted through in-depth interviews with media literacy teachers all over the country. Despite the many challenges, all teachers identify the potential of media education to strengthen some of the key competences of the students and to improve their motivation and academic performance. They also identify potential to change positively school culture by transforming teachers into “cultural mediators” (Morcellini, 2007 and by supporting the formation of a “participative culture” (Jenkins & Kelley, 2013 in schools. This research recommends focusing education reform on spreading the media education pedagogy to the entire curriculum in order to embrace the new digital education paradigm in the future.

    2014-01-01

    To compare the masticatory and cervical muscle tenderness and pain sensitivity in the hand (remote region) between patients with temporomandibular disorders (TMD) and healthy controls. Twenty female subjects were diagnosed with chronic TMD, and 20 were considered healthy. Subjects completed the Neck Disability Index and Limitations of Daily Functions in a TMD questionnaire. Tenderness of the masticatory and cervical muscles and pain sensitivity in the hand were measured using an algometer. Three-way mixed analysis of variance (ANOVA) evaluated differences in muscle tenderness between groups. One-way ANOVA compared pain sensitivity in the hand between groups. Effect sizes were assessed using Cohen guidelines. Significantly increased masticatory and cervical muscle tenderness and pain sensitivity in the hand were found in subjects with TMD when compared with healthy subjects. Moderate to high effect sizes showed the clinical relevance of the findings. The results of this study have highlighted the importance of assessing TMD patients not only in the craniofacial region but also in the neck and other parts of the body. Future studies should focus on testing the effectiveness of treatments addressing the neck and the pain sensitivity in the hand in patients with TMD.

    Full Text Available The media establish, in large part, the patterns of visibility and public recognition of collective identities. We define media identities as those that are the object of production and diffusion by the media. From this discourse, the communities and individuals elaborate media-influenced identifications; that is, processes of recognition or banishment; (rearticulating the identity markers that the media offer with other cognitive and emotional sources. The generation and appropriation of the identities are subjected to a media hierarchisation that influences their normalisation or marginalisation. The identities presented by the media and assumed by the audience as part of the official, hegemonic discourse are normalised, whereas the identities and identifications formulated in popular and minority terms are marginalised. After presenting this conceptual and analytical framework, this study attempts to outline the logics that condition the presentation, on the one hand, andthe public recognition, on the other hand, of contemporary identities.

    To assess the immediate effects on vertical mouth opening, orofacial mechanosensitivity, and lumbar and suboccipital mobility after adding a myofascial induction technique to a multimodal protocol in subjects with temporomandibular disorders (TMD). A randomized and double-blind controlled trial was carried out. University-based physical therapy research clinic. Sixty subjects (35±11.22 years) with TMD, and restricted mobility of the mandibular condyles and the first cervical vertebrae, were recruited and randomized to either a control group (CG) (n=30) or an experimental group (EG) (n=30). The CG underwent a neuromuscular technique over the masseter muscles and passive hamstring muscle stretching. A suboccipital muscle inhibition technique was added to this protocol in the EG. Primary measurements were made of vertical mouth opening and pressure pain threshold of the masseter muscles. Secondary outcome measures included pressure algometry of the trigeminal nerve, suboccipital range of motion, and lumbar spine mobility, assessed with the sit-and-reach (SAR) test and lumbar forward bending. All evaluations were collected at baseline and immediately after intervention. In the intragroup comparison, the EG observed an increase in suboccipital flexion (p0.05). The inclusion of a myofascial induction maneuver in a protocol combining local (neuromuscular treatment) and distal techniques (hamstring stretching) in subjects with TMD has no impact on improving mouth opening, suboccipital and lumbar mobility, and orofacial sensitivity to mechanical pressure.

    Full Text Available Abstract Background Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic radiographs. We aimed to determine if directed screening for carotid stenosis with ultrasound is indicated in individuals with such calcifications. Methods This was a cross-sectional study. Carotid ultrasound examinations were performed on consecutive persons, with findings of calcifications in the area of the carotid arteries on panoramic radiography that were otherwise eligible for asymptomatic carotid endarterectomy. Results Calcification in the area of the carotid arteries was seen in 176 of 1182 persons undergoing panoramic radiography. Of these, 117 fulfilled the inclusion criterion and were examined with carotid ultrasound. Eight persons (6.8%; 95% CI 2.2-11.5% had a carotid stenosis - not significant over the 5% pre-specified threshold (p = 0.232, Binomial test. However, there was a significant sex difference (p = 0.008, as all stenoses were found in men. Among men, 12.5% (95%CI 4.2-20.8% had carotid stenosis - significantly over the 5% pre-specified threshold (p = 0.014, Binomial test. Conclusions The incidental finding of calcification in the area of the carotid arteries on panoramic radiographs should be followed up with carotid screening in men that are otherwise eligible for asymptomatic carotid endarterectomy.

    Otitis media with effusion (OME) is a process, which goes on by inner side of intact tympanic membrane. Oligosymptomatic and deceitful course is characteristics for this disease. Fluid filling middle ear structures causes long-lasting hypoacusis. Chronic consequences of the OME are morphologic changes within the middle ear, especially in the tense part of the tympanic membrane, causing strengthened conductive hypoacusis. The OME morbidity peak falls in 3-6 year of life, which is the period of the most intense development of the child and speech creation. Discreet symptoms, like fullness and feeling of fluid movement, not advanced hypoacusis, causes many problems in putting proper diagnosis. There should be aimed at quick detection of these symptoms, otherwise long persisting hypoacusis can have permanent negative influence on child's development. The aim of this study was to show the effectiveness of screening in population of children in their pre-elementary school and at the elementary school, focused on discreet pathology of the middle ear (OME) and low grade conductive hypoacusis. The study has a prospective character. Screening has covered a group of 927 children, aged 5-10. Examination concerned a population of healthy children, attending pre-elementary school and first classes of elementary school. Past otiatric history was the first step of diagnostic process, followed by full ENT examination and tympanometry. Special stress was laid on collecting medical history directed on the existence of discreet symptoms, like: low-grade hypoacusis manifested by some elements of child's behaviour (non responding on instructions, louder speaking, higher volume in TV-set), articulation disorders, difficulties in communication and problems at school. A group of 116 children actually presenting aural complaints lasting several weeks to several years were separated from the while examined group. Every 10th child from analyzed population submitted hypoacusis, 32 children had

    This study aimed to assess the nutritional status, measured by MNA, and its association with socio-demographic indicators and health related characteristics of a representative sample of community dwelling elderly subjects. Cross-sectional study. Community dwelling elderly individuals living in rural communities in Lebanon. 1200 elderly individuals aged 65 years or more. Socio-demographic indicators and health related characteristics were recorded during a standardized interview. Nutritional status was assessed through Mini Nutritional Assessment (MNA). The 5-item GDS score and the WHO-5-A score were used to assess mood, whereas Mini Mental Status (MMS) was applied to evaluate cognitive status. The prevalence of malnutrition and risk of malnutrition was 8.0% respective 29.1% of the study sample. Malnutrition was significantly more frequent in elderly subjects aged more than 85 years, in females, widowed and illiterate people. Moreover, participants who reported lower financial status were more often malnourished or at risk of malnutrition. Regarding health status, poor nutritional status was more common among those reporting more than three chronic diseases, taking more than three drugs daily, suffering from chronic pain and those who had worse oral health status. Also, depressive disorders and cognitive dysfunction were significantly related to malnutrition. After multivariate analysis following variables remained independently associated to malnutrition: living in the governorate of Nabatieh (ORa 2.30, 95% CI 1.35 -3.93), reporting higher income (ORa 0.77, 95% CI 0.61-0.97), higher number of comorbidities (ORa 1.22, 95% CI 1.12-1.32), chronic pain (ORa 1.72, 95% CI 1.24-2.39), and depressive disorders (ORa 1.66, 95% CI 1.47-1.88). On the other hand, better cognitive functioning was strongly associated with decreased nutritional risk (ORa 0.27, 95%CI 0.17-0.43). Our results highlighted the close relationship between health status and malnutrition. The

  14. Media violence.

    Science.gov (United States)

    Cantor, J

    2000-08-01

    Research on the effects of media violence is not well understood by the general public. Despite this fact, there is an overwhelming consensus in the scientific literature about the unhealthy effects of media violence. Meta-analyses show that media-violence viewing consistently is associated with higher levels of antisocial behavior, ranging from the trivial (imitative violence directed against toys) to the serious (criminal violence), with many consequential outcomes in between (acceptance of violence as a solution to problems, increased feelings of hostility, and the apparent delivery of painful stimulation to another person). Desensitization is another well-documented effect of viewing violence, which is observable in reduced arousal and emotional disturbance while witnessing violence, the reduced tendency to intervene in a fight, and less sympathy for the victims of violence. Although there is evidence that youth who are already violent are more likely to seek out violent entertainment, there is strong evidence that the relationship between violence viewing and antisocial behavior is bidirectional. There is growing evidence that media violence also engenders intense fear in children which often lasts days, months, and even years. The media's potential role in solutions to these problems is only beginning to be explored, in investigations examining the uses and effects of movie ratings, television ratings, and the V-chip, and the effects of media literacy programs and public education efforts. Future research should explore important individual differences in responses to media violence and effective ways to intervene in the negative effects.

    2011-02-01

    This study explores the psychosocial working conditions of 7930 Swedish 9th grade students, distributed over 475 classes and 130 schools, in relation to their subjective health using multilevel modeling. At the individual level, students with "strained" working conditions in school (i.e. those experiencing a high level of demands in combination with a low level of control) demonstrated significantly worse health compared to students in "low-strain" situations. "Strained" conditions in combination with a weak school-related sense of coherence were especially unfavourable for health. These findings remained significant when support from teachers, school marks, norm-breaking behaviours, family-relations and certain class- and school-contextual conditions were adjusted for. Thus, while demands are an essential part of school work, this study suggests that high levels of control and a strong school-related sense of coherence can protect against the more detrimental effects on health that high demands at school may cause.

    2016-03-01

    Full Text Available Introduction: The scope of the research was a more detailed understanding of the influence of social media and the importance of student’s usage of social media context in relation to medical information. The research aimed to increase the understanding of social media and the impact on medical information use, informing policy and practice while highlighting gaps in the literature and areas for further research. Methods: The search of PubMed database was performed in October 2015, using terms to identify peer-reviewed research in which social media technologies were an important feature for health occupations, premedical, pharmacy, nursing or medical students. A systematic approach was used to retrieve papers and extract relevant data. Results: There were initially identified 435 studies involving social media, healthcare information and medical students subject headings (MeSH terminology. After filtering for free full text articles, and exclusion of not students or social media specific ones, 33 articles were reviewed. The majority of the studies were interventional studies that either assessed the outcomes of online discussion groups or teaching methods through social media. The majority of studies focused on the use of social media as a teaching tool, how students use it and the implications upon their education. The largest number of original papers was published in 2013. Facebook, Podcasts, Multiplayer virtual worlds, Blogs, and Twitter were identified as being used by medical students. Conclusion: Social media is used as a tool of information for students mainly as the means for engaging and communicating with students.

    There are two different types of media bias. One bias, which we refer to as ideology, reflects a news outlet's desire to affect reader opinions in a particular direction. The second bias, which we refer to as spin, reflects the outlet's attempt to simply create a memorable story. We examine competition among media outlets in the presence of these biases. Whereas competition can eliminate the effect of ideological bias, it actually exaggerates the incentive to spin stories.

    The public information media provides information on current events (news), entertainment (programming), and opinions offered by trusted public sources (e.g., business, academic or religious spokespersons, journalists, and government officials). Consequently, it is a major force in shaping a populace's attitudes toward significant social issues and of great interest to intervention planners. The chapter attempts to provide modelers and intervention analysts alike with sufficient understanding of media mechanisms and current research that they can begin contributing to, and benefiting from this important area of study.

    The present study was undertaken to establish an optimal medium for primary culture initiation and maintenance of T. evansi isolated from different mammalian hosts of diverse geographical regions of India viz. donkey/1 (Hardoi, Uttar Pradesh), donkey/2 (Junagarh, Gujarat), pony/1 (Hisar, Haryana), camel/1 (Bikaner, Rajasthan) which represented isolates 1, 2, 3 and 4, respectively. Primary cultures were initiated with all four isolates in five different in vitro cultivation media with seeding density of 1 × 10(6) trypanosomes/ml. The parasites of all four isolates could remain viable only for 48 h in medium E (Alsever's solution) and for 72 h in medium A, C and D. Parasites reached to a maximum density (2.5-3.75 × 10(6)/ml) within 24 h and thereafter, a sharp decline (0.5-0.75 × 10(6)/ml) in the next 72 h was observed in 1, 2 and 3 isolates cultured in medium B. In isolate 4, parasite counts got more than doubled in 24 h and then decreased gradually up to sixth day post initiation of cultivation which thereafter increased gradually up to 34 days and a constant parasite number of 10(5)/ml could be achieved for 90 days in medium B. During this prolonged culture the trypanosomes retained their long slender morphology and infectivity to mice.

    In order to assess the quality of streams susceptible to contamination by pesticides we apply biochemical and genotoxic biomarkers in the Neotropical fish Prochilodus lineatus submitted to in situ tests. Fish were caged, for 96 h, in two streams located in areas with intensive use of pesticides, the Apertados (AP) and the Jacutinga (JC), and in a small stream (Godoy stream — GD) found inside a forest fragment adjacent to a State Park. Biochemical parameters, such as biotransformation enzymes 7-ethoxyresorufin-O-deethylase (EROD) and glutathione-S-transferase (GST), non-protein thiols (NPSH), lipoperoxidation (LPO), protein carbonylation (PCO) and acetylcholinesterase (AChE) were evaluated in various fish organs, as well as genotoxic biomarkers (damage to DNA and occurrence of micronuclei and erythrocyte nuclear abnormalities). Samples of water and sediment were collected for analysis of metals (Cu, Cr, Pb, Ni, Mn, Cd and Zn), organochloride pesticides, and triazine and glyphosate herbicides. We observed an increase in liver GST activity in fish at AP and gill GST activity in fish at JC. An increase in liver LPO was also observed in fish exposed to AP and JC. The same animals also exhibited increased DNA damage and erythrocyte nuclear abnormalities (ENAs) compared to the fish kept in GD. A number of compounds showed concentrations higher than the permitted levels, in particular, dichlorodiphenyltrichloroethane (DDT), its metabolites dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexanes (HCH), heptachloride, diclofluanid and aldrins. These pesticides were detected at higher concentrations in water and sediment samples from AP, followed by JC and GD. The Integrated Biomarker Response Index (IBR) indicated that AP and JC (AP: 21.7 > JC: 18.5 > GD: 12.6) have the worst environmental quality. Integrated biomarker analysis revealed that the alterations observed related well with the levels of environmental contaminants

    Full Text Available To characterize the geological, hydrogeological, hydrochemical, and hydrobacterial aspects of the surface and groundwater in the floodplain of the Paraíba do Sul river in Tremembé municipality, the water levels of the Quaternary sedimentary aquifer experimental site was monitored based on four wells and eight associated piezometers with daily measures of water levels in continuous operation since December 3, 2009. In addition, data from a modular weather station in operation since March 2010 and data from the quality of surface water and groundwater have been analyzed in the period between March 2010 and March 2011. The water balance between April 2010 and March 2011 was estimated to verify the periods of water deficiency and excess. Data loggers installed in the piezometers enabled daily groundwater levels monitoring to establish the influence of the Paraíba do Sul river in the water levels of the Quaternary sedimentary aquifer and also they allowed the determination of the water loss to the atmosphere. A hydrogeological model with simplified equations, based on hydraulics parameters obtained in the wells pump tests, was implemented to calculate the amount of daily evapotranspiration and the average distance of the water loss from the wells to the atmosphere. An evaporation rate of 83.4 m3/h from the open-pit sand mine located at 212.2 m and of 89.2 m3/h for the one at 885.0 m average distance from the monitoring wells were observed. Chemical and bacteriological analysis involving multiple parameters were performed in the period from March 2010 to March 2011 in groundwater collected in wells, in the open-pit mines and in the waters of the Paraíba do Sul river. The results allowed to observe the influences of the Paraíba do Sul river as well as the contamination from fertilizers and pesticides from the agriculture practiced in the floodplain area on the quality of the groundwater.

    2011-12-01

    Full Text Available McChesney described one of the biggest problem of journalism as “the journalists have any power to be autonomous from owners and advertisers” (2008:58. Most of media market have been dominated by a few media companies, furthermore a few media conglomerates who had expanded with merger and acquisitions transactions control the biggest part of the global media and entertainment industry. This concentration of media power and penetration of commercial interest in the news media has been seen as affecting the mode of news, profession of journalism and outputs, and consequently, diversity and democracy itself. research aims to examine the potential of social media to create autonomous spaces for journalists working under the commercial pressure of their corporation. In order to analyze this new kind of news area for journalism, three different qualitative methods are used in different steps of research. First, social media utterances of popular journalists were observed to reveal their journalistic intention and they were also evaluated using two case stud- ies about social events which had been tweeted multiple times for many Turkish users (trending topics in Twitter’s agenda. After diversifying the sample, different types of journalists’ social media experiments, including their responsibility to corporations, were examined by qualitative methods including in-depth interviews. Our findings show that although interactions between the journalists and audience observably changed, Twitter, as with other social networks, didn’t diminish the influence of corporate interests on journalism in Turkish media organisations.

    Full Text Available Contemporary media culture is de fi ned by the logic of the victorious spectacle expanding to all areas of life. Post-modern capitalism has turned everyday life and culture into entertainment with the help of the spectacular. In fact, such entertainment results in a fake sense of happiness, pop mainstream, the swallowing up alternatives and therefore the creation of a passive consumer society. The media today have a unique power of overwhelming a person with information. They enable a modern person to know much, but understand little. This discussion has cast some light on very popular reality shows, the body and sports. It concludes with a re fl ection on modern media, which leave a person of this age with a patchwork identity.

  1. Doing social media analytics

    Directory of Open Access Journals (Sweden)

    Phillip Brooker

    2016-07-01

    Full Text Available In the few years since the advent of ‘Big Data’ research, social media analytics has begun to accumulate studies drawing on social media as a resource and tool for research work. Yet, there has been relatively little attention paid to the development of methodologies for handling this kind of data. The few works that exist in this area often reflect upon the implications of ‘grand’ social science methodological concepts for new social media research (i.e. they focus on general issues such as sampling, data validity, ethics, etc.. By contrast, we advance an abductively oriented methodological suite designed to explore the construction of phenomena played out through social media. To do this, we use a software tool – Chorus – to illustrate a visual analytic approach to data. Informed by visual analytic principles, we posit a two-by-two methodological model of social media analytics, combining two data collection strategies with two analytic modes. We go on to demonstrate each of these four approaches ‘in action’, to help clarify how and why they might be used to address various research questions.

  2. Enhancement of motor learning by focal intermittent theta burst stimulation (iTBS) of either the primary motor (M1) or somatosensory area (S1) in healthy human subjects.

    Motor rehabilitation after brain damage relies on motor re-learning as induced by specific training. Non-invasive brain stimulation (NIBS) can alter cortical excitability and thereby has a potential to enhance subsequent training-induced learning. Knowledge about any priming effects of NIBS on motor learning in healthy subjects can help to design targeted therapeutic applications in brain-damaged subjects. To examine whether complex motor learning in healthy subjects can be enhanced by intermittent theta burst stimulation (iTBS) to primary motor or sensory cortical areas. Eighteen young healthy subjects trained eight different arm motor tasks (arm ability training, AAT) once a day for 5 days using their left non-dominant arm. Except for day 1 (baseline), training was performed after applying an excitatory form of repetitive transcranial magnetic stimulation (iTBS) to either (I) right M1 or (II) S1, or (III) sham stimulation to the right M1. Subjects were randomly assigned to conditions I, II, or III. A principal component analysis of the motor behaviour data suggested eight independent motor abilities corresponding to the 8 trained tasks. AAT induced substantial motor learning across abilities with generalisation to a non-trained test of finger dexterity (Nine-Hole-Peg-Test, NHPT). Participants receiving iTBS (to either M1 or S1) showed better performance with the AAT tasks over the period of training compared to sham stimulation as well as a bigger improvement with the generalisation task (NHPT) for the trained left hand after training completion. Priming with an excitatory repetitive transcranial magnetic stimulation as iTBS of either M1 or S1 can enhance motor learning across different sensorimotor abilities.

  4. Heat stress in urban areas: Indoor and outdoor temperatures in different urban structure types and subjectively reported well-being during a heat wave in the city of Leipzig

    Directory of Open Access Journals (Sweden)

    Ulrich Franck

    2013-04-01

    Full Text Available Climate projections for Leipzig suggest elevated minimum and maximum temperatures as well as more frequent days with high temperatures. Hence, climate change is threatening human well-being and health. People spend the majority of their time indoors. Therefore, indoor temperatures (especially during the night are of special importance with respect to well-being and health. Indoor air temperature depends on outdoor air temperatures, but is for example modified by type of urban structure, housing area, and may be also influenced by differences in the behavior of the inhabitants. Especially in cities, outdoor air temperatures depend on urban structure e.g. housing density, building arrangement, unpaved areas, types of urban structures, urban green, and other factors. Hence, the questions arise how types of urban structures are related to inner-urban temperature differences and how outdoor air temperatures influence indoor temperatures in dependence on urban housing conditions. This work is a part of a pilot study conducted during the summer 2010 which gathered data from remote sensing, mobile measurements, stationary measurements of air temperatures and relative humidity in areas with different housing structures, and of indoor as well as outdoor temperatures in occupied apartments. Household-survey data reported the subjective perception of heat stress. The study resulted in rather complex relationships between type of housing areas, indoor and outdoor temperatures, morning and evening temperatures, indoor and outdoor temperatures as well as subjective heat perception. Green spaces and types of residential areas are related to air temperatures. More green resulted in lower temperatures. Temperatures have a tendency to increase with increasing story number and are significantly higher in the top floor. An indoor heat island effect corresponding to the outdoor effect could be shown for the homes: Distance to city center is a predicting variable for

    The media information review, requested by the Communications Subcommittee of the Technical Steering Panel (TSP), provides a general indication of the media's areas of interests with regard to the Hanford Environmental Dose Reconstruction (HEDR) Project. This review briefly assesses 14 newspaper articles/advertisements collected between January and June 1992 by Battelle Pacific Northwest Laboratories (BNW). Articles that mention the project, activities closely associated with it, or members of the Panel were included in the analysis. The sources of the articles and announcements include most newspapers in the Northwest (dailies and weeklies) as collected and distributed to the US Department of Energy (DOE) and Hanford contractors by Westinghouse Hanford Company, Communications. National and international media coverage was provided during the review period by Burrelle's Press Clipping Service, New York, and A.T.P., New Jersey. The articles and advertisements represent those collected and judged applicable to issues and activities associated with the Technical Steering Panel and the Hanford Environmental dose Reconstruction Project. The collection is not considered inclusive of every written account of the subject, but as good a representative collection as reasonable. This review is unscientific and is not meant to display a technical analysis of the materials.

    1988-01-01

    Nigeria needs to embrace technology and pursue private media ownership in order to achieve a democratic media. In recent years, mass media in Africa has become a force with augmenting power that has influenced government and regimes. A democratization of the African media is reliant on media ownership and accessibility of information. Within Nigeria, there is a government monopoly of the media and therefore a road block in the free flow of information. As well, Nigeria's current economic situation has made media accessibility an extravagance. The electronic media is far from effective as many areas have poor reception, no electricity, or face a language barrier. Because most of the print media is written in English, many Nigerians cannot comprehend the printed news.

    2011-08-01

    Full Text Available As a focus of study, ‘social media’ tend to lack definitional clarity and grounding in theories of media and text. This paper establishes and discusses a conceptual framework for defining social media as communicative genres, constituted by the interplay between interactive functionalities configured at the software level and the invocation and appropriation of various software functionalities to achieve specific purposes in and through users’ actual communicative practices. I suggest that social media might be seen as particularly dynamic genres, subject to continuous disruption and uncertainty,owing to their deinstitutionalised and participatory character, and the shifting roles of producers and recipients in the networks and conversations that make up social media content.

  9. Managing Media: Segmenting Media Through Consumer Expectancies

    Directory of Open Access Journals (Sweden)

    Matt Eastin

    2014-04-01

    Full Text Available It has long been understood that consumers are motivated to media differently. However, given the lack of comparative model analysis, this assumption is without empirical validation, and thus, the orientation of segmentation from a media management perspective is without motivational grounds. Thus, evolving the literature on media consumption, the current study develops and compares models of media segmentation within the context of use. From this study, six models of media expectancies were constructed so that motivational differences between media (i.e., local and national newspapers, network and cable television, radio, and Internet could be observed. Utilizing higher order statistical analyses the data indicates differences across a model comparison approach for media motivations. Furthermore, these differences vary across numerous demographic factors. Results afford theoretical advancement within the literature of consumer media consumption as well as provide media planners’ insight into consumer choices.

    Social media platforms have become popular as means of communications in emergency management. Many people use social media sites such as Facebook and Twitter on a daily basis including during disaster events. Emergency management agencies (EMAs) need to recognize the value of not only having a presence on social media but also actively engaging stakeholders and the public on these sites. However, identifying best practices for the use of social media in emergency management is still in its infancy. The objective of this article is to begin to create or further define best practices for emergency managers to use social media sites particularly Facebook and Twitter in four key areas: 1) implementation, 2) education, 3) collaboration, and 4) communication. A list of recommendations of best practices is formulated for each key area and results from a nationwide survey on the use of social media by county EMAs are discussed in this article.

    2011-04-01

    Full Text Available This article focuses on the transpositions of media and nature through recent art projects such as Harwood, Wright and Yokokoji’s Eco Media (Cross Talk and Garnet Hertz’s Dead Media lab. The Eco Media project developed new modes of thinking media (ecology through a tracking of the intensities of nature. However, in this case the medium is understood in a very broad sense to cover the ecosystem as a communication network of atmospheric flows, tides, reproductive hormones, scent markers, migrations or geological distributions. The project(s do not focus solely on the ecological crisis that has been a topic of media representations for years, but they seem to engage with a more immanent level of media ecology in a manner that resembles Matthew Fuller’s call for ‘Art for Animals.’ Media is approached from the viewpoint of animal perceptions, motilities and energies (such as wind that escape the frameworks of ‘human media.’ In this context the rhetorical question of the Ecomedia project concerning non-human media is intriguing: ‘Can “natural media” with its different agencies and sensorium help to rethink human media, revealing opportunities for action or areas of mutual interest?’ With the Dead Media Lab project, this article extends the discussion concerning media ecologies to media archaeology as well. Through such transversal connections, it investigates intensive transpositions not only in terms of nature/media, but also as temporal intertwinings of past, ‘dead’ media and the contemporary media sphere. Despite the focus on the old media of nature, such projects are emblematic of concerns that stem from a high-tech network culture. Ideas stemming from animal worlds and nature are increasingly used as tools to understand high tech culture, and they expand the notion of ‘medium’ to take into account non-human energies of intensive and topological kinds.

    2017-11-10

    We demonstrate that exposure to the news media causes Americans to take public stands on specific issues, join national policy conversations, and express themselves publicly-all key components of democratic politics-more often than they would otherwise. After recruiting 48 mostly small media outlets, we chose groups of these outlets to write and publish articles on subjects we approved, on dates we randomly assigned. We estimated the causal effect on proximal measures, such as website pageviews and Twitter discussion of the articles' specific subjects, and distal ones, such as national Twitter conversation in broad policy areas. Our intervention increased discussion in each broad policy area by ~62.7% (relative to a day's volume), accounting for 13,166 additional posts over the treatment week, with similar effects across population subgroups.

    2014-07-01

    Full Text Available From educational gaming through portable e-readers to cell phones, media are interpenetrating educational spaces and activities. Accordingly, understanding media in environmental or ecological terms has become increasingly important for education internationally. In North America, for example, the centenary of McLuhan’s birth has focused attention on approaches to media – whether oral, textual, electronic or digital– as a kind of environment in which education takes place. In parts of Europe, the so-called mediatic turn – following on the linguistic and iconic turns – has similarly emphasized the role of media as a condition for the possibility of educational activities and programs. With a few exceptions1 the papers in this special issue were first presented at the conference «Educational Media Ecologies: International Perspectives» which took place at the University of Paderborn, Germany, on March 27–28, 2012.2 The event was an interdisciplinary and transatlantic endeavor to bring together a wide range of perspectives on various issues relevant to educational media ecologies,3 and on related debates on mediation, medialization, mediatization, and mediality.4 The purpose of this volume, like the conference, is to foster and deepen international dialogue in the area of educational media. Areas of research and scholarship relevant to this dialogue include educational media, media literacy, educational philosophy, and media and cultural studies. The contributions, described below, put conceptual issues as well as social practices and applications at the center of the debate. Klaus Rummler opens the issue by clarifying the concept of ecology itself. Referencing a range of work over the past 50 years, Rummler describes how ecological models have been cast in sociological, semiotic, cultural, mediatic and other terms, and he explains the implications of these various perspectives for the study of educational contexts.

    2006-01-01

    This book presents a compilation of state-of-the art studies on gas and vapor transport processes in porous and fractured media. A broad set of models and processes are presented, including advection/diffusion, the Dusty Gas Model, enhanced vapor diffusion, phase change, coupled processes, solid/vapor sorption, and vapor-pressure lowering. Numerous applications are also presented that illustrate these processes and models in current problems facing the scientific community. This book fills a gap in the general area of transport in porous and fractured media; an area that has historically been dominated by studies of liquid-phase flow and transport. This book identifies gas and vapor transport processes that may be important or dominant in various applications, and it exploits recent advances in computational modeling and experimental methods to present studies that distinguish the relative importance of various mechanisms of transport in complex media.

    1998-10-01

    Porous solids filled with liquid or gas play an important role in engineering, e.g., in material science, petroleum industry, chemical engineering, and soil mechanics as well as in biomechanics. Although porous media are of considerable practical significance the description of their mechanical and thermodynamical behavior has been unsatisfactory for a long time. The theory to describe the complex thermodynamical behavior of such saturated porous solids has come to certain well-founded conclusions only recently. It is the goal of this paper to show the historical development of the porous media theory, which already started in the eighteenth century, formed in some areas by polemic disputes and tragic events in the lifes of the scientists involved. Furthermore, the current state of the research into this subject is discussed, whereby the state of the development of the material independent basic equations and the constitutive theory is illustrated. For a certain class of models general theorems, such as minimum and maximum problems, are derived and the uniqueness of solutions of boundary value problems is proved. (orig.)

    2016-12-01

    Full Text Available The article considers the social media as a relatively new tool for electoral and political activities for creating a positive image of political parties and candidates (on the example of the European Parliament. The social media are becoming increasingly important in the nowadays world politics due to the growing number of the Internet users, the fall in the popularity of traditional media, and the fast spread of new media as well as the transformation of the Internet into the area for active political actions. The key role in the formation of the political image belongs to political institutions (parties, government agencies, certain politicians and public figures, as well as to representatives of the electorate, i.e. population. The analysis of the efforts of various political actors in the social media allows to identify their three basic functions: a tool to increase voter turnout; a tool to increase the popularity of candidates and parties; a tool to increase public awareness of the political and electoral processes in general. Currently the most serious obstacle for strategic studies of social networks is the tremendous pace of their technological development that complicates long-term predictions in the field. However, despite the lack of universally accepted criteria for assessing the efficiency of political activities in the social media, the author believes that the key success factor is the so-called “permanent presence” of electoral subjects in the Internet.

    2016-04-01

    Full Text Available This article examines social media as a relatively new tool of electoral and political activity aimed at creating a positive image of political parties and candidates to the European Parliament. In the modern world of politics it is becoming increasingly important due to such factors as the growing number of World Wide Web users, the decline in the traditional media popularity and the rapid spread of new media, as well as the transformation of the Internet space into the platform for active political interactions. The key role in realizing the task of forming political image belongs to political institutions (parties, state bodies, politicians and social activists, as well as population representatives. The analysis of the efforts of various political subjects in the social media roughly demonstrates three functions of this new phenomenon: social media as a turnout increase tool, as a tool of increasing the recognition of candidates and parties by population; as a tool of informing the population about political and electoral processes in society. Currently, the main obstacle for the strategic research in this area is the fact that social networking technologies are rapidly developing, that embarrasses in making long-term prediction on its use. In spite of the absence of recognized criteria giving the opportunity to evaluate political activity in social media, the key efficiency criteria and success factor is so called “permanent presence” of electoral activity subjects in the Internet.

    To explore media preferences and use among young children, as well as to obtain information about parental supervision methods and beliefs about media. Ninety parents of three- to six-year-olds, recruited from a relatively economically advantaged area in the United Kingdom, completed a media opinion survey. Although traditional television remains the favourite type of media platform among young children, touchscreen devices are gaining in popularity, and may promote simultaneous multi-screen use. Moreover, parents believe that the effects of media on developmental outcomes are generally positive. However, they do monitor the content of traditional and new media their children are exposed to. This study shows an emerging evidence of concurrent multi-screen use among very young children. More detailed examination of early media multitasking, and its relationship to cognitive and behavioural outcomes, is necessary. ©2016 Foundation Acta Paediatrica.

    Full Text Available This essay examines a subject rarely emphasized in the studies on public interest issues reported in the print media. Drawing on a review of the journalistic content produced by 53 newspapers from every state in the federation and 4 national weekly magazines, the paper analyzes a sample of 1,184 articles, editorials, columns, interviews, and reports on subjects of immediate interest to the media, journalism, and/or media companies. Throughout 2003, 2004, and 2005, news pieces were compiled containing keywords, including “media and democracy,” “concentration of ownership,” “television regulation.” The analysis found that the print media provides insufcient and inadequate coverage of these issues, reserving more extensive coverage only to those questions nearest and dearest to it, such as the freedom of expression.

Utilizam-se também como dispositivos analíticos os estudos de Zygmunt Bauman, apoiados em Thomas Mathiesen, acerca do sinóptico como novo mecanismo de poder em funcionamento na mídia, e alguns assinalados por Rosa Maria Bueno Fischer. O que se pretende é discutir a materialidade lingüístico-discursiva do depoimento-confissão de uma mulher negra, pobre e idosa, selecionado da novela Páginas da vida, exibida pela TV Globo, em 2006, a fim de se apreenderem os efeitos de sentido que poderiam construir um dos primeiros sinais de sua "anormalidade". Tal discussão aponta para a reinvenção de uma outra figura do "anormal", com implicações éticas, uma vez que a mulher subverte práticas discursivas advindas de certos saberes e poderes.Based on Foucault studies, this article discusses notions such as masturbation, anomaly and confession technique, associated to investigation related to the female subjectivities exposed by media, whose images present models for the construction of new subjects.

  5. Negotiated media effects. Peer feedback modifies effects of media's thin-body ideal on adolescent girls.

    Veldhuis, Jolanda; Konijn, Elly A; Seidell, Jacob C

    2014-02-01

    The present study introduces a theoretical framework on negotiated media effects. Specifically, we argue that feedback of peers on thin-body ideal media images and individual dispositions guide effects on adolescent girls' psychosocial responses to media exposure. Therefore, we examined the thin-body ideal as portrayed in media and peers' feedback on such thin-ideal images in their combined effects on adolescent girls' body dissatisfaction, objectified body consciousness, and social comparison with media models. Hence, media models and peer comments were systematically combined as incorporated entities in YouTube-formats. Hypotheses were tested in a 3 (media models: extremely thin vs. thin vs. normal weight)×3 (peer comments: 6kg-underweight vs. 3kg-underweight vs. normal-weight)×2 (appearance schematicity: lower vs. higher) between-subjects design (N=216). Results showed that peer comments indicating that a media model was 'only 3kg-underweight' exerted most negative responses, particularly in girls who strongly process appearance relevant information. Peer feedback interacts with media models in guiding perceptions of what is considered an 'ideal' body shape. Results highlight the important role of peers as well as individual predispositions in view of understanding how thin-ideal media images may impact adolescent girls' body image concerns.

    Full Text Available The 21st century has marked an unprecedented advancement of new media. New media has become so pervasive that it has penetrated into every aspect of our society. New media literacy plays an essential role for any citizen to participate fully in the 21st century society. Researchers have documented that literacy has evolved historically from classic literacy (reading-writing-understanding to audiovisual literacy to digital literacy or information literacy and recently to new media literacy. A review of literature on media literacy reveals that there is a lack of thorough analysis of unique characteristics of new media and its impacts upon the notion of new media literacy. The purpose of the study is to unpack new media literacy and propose a framework for a systematic investigation of new media literacy.

    Understanding the family dynamic surrounding media use is crucial to our understanding of media effects, policy development, and the targeting of individuals and families for interventions to benefit child health and development. The Families, Parenting, and Media Workgroup reviewed the relevant research from the past few decades. We find that child characteristics, the parent-child relationship, parental mediation practices, and parents' own use of media all can influence children's media use, their attitudes regarding media, and the effects of media on children. However, gaps remain. First, more research is needed on best practices of parental mediation for both traditional and new media. Ideally, this research will involve large-scale, longitudinal studies that manage children from infancy to adulthood. Second, we need to better understand the relationship between parent media use and child media use and specifically how media may interfere with or strengthen parent-child relationships. Finally, longitudinal research on how developmental processes and individual child characteristics influence the intersection between media and family life is needed. The majority of children's media use takes place within a wider family dynamic. An understanding of this dynamic is crucial to understanding child media use as a whole.

    2008-01-01

    American youth are awash in media. They have television sets in their bedrooms, personal computers in their family rooms, and digital music players and cell phones in their backpacks. They spend more time with media than any single activity other than sleeping, with the average American eight- to eighteen-year-old reporting more than six hours of daily media use. The growing phenomenon of "media multitasking"--using several media concurrently--multiplies that figure to eight and a half hours of media exposure daily. Donald Roberts and Ulla Foehr examine how both media use and media exposure vary with demographic factors such as age, race and ethnicity, and household socioeconomic status, and with psychosocial variables such as academic performance and personal adjustment. They note that media exposure begins early, increases until children begin school, drops off briefly, then climbs again to peak at almost eight hours daily among eleven- and twelve-year-olds. Television and video exposure is particularly high among African American youth. Media exposure is negatively related to indicators of socioeconomic status, but that relationship may be diminishing. Media exposure is positively related to risk-taking behaviors and is negatively related to personal adjustment and school performance. Roberts and Foehr also review evidence pointing to the existence of a digital divide--variations in access to personal computers and allied technologies by socioeconomic status and by race and ethnicity. The authors also examine how the recent emergence of digital media such as personal computers, video game consoles, and portable music players, as well as the media multitasking phenomenon they facilitate, has increased young people's exposure to media messages while leaving media use time largely unchanged. Newer media, they point out, are not displacing older media but are being used in concert with them. The authors note which young people are more or less likely to use several

    Full Text Available A primordial aspect of the Sartrian critique of alienation concerns understanding the analytic ideology as the domination of materiality over the symbolic, in other words as the reification of the human, and therefore as anticulture. In the context of contemporary nihilism, the decoding of the mechanisms which consign praxis to the practico-inert requires a critique of the relations between the social sciences and philosophy, which in its turn implies a new theory of the relation between what Sartre calls the "notion" (the area of subjectivity and the "concept" (objectivity, From this perspective, the deconstruction of the established frontiers between the social sciences and philosophy, and between the conceptual and the narrative, is corelative to a redefinition of the relation between theory and practice.

  6. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other. 

  7. Armenian media coverage of science topics

    Mkhitaryan, Marie

    2016-12-01

    The article discusses features and issues of Armenian media coverage on scientific topics and provides recommendations on how to promote scientific topics in media. The media is more interested in social or public reaction rather than in scientific information itself. Medical science has a large share of the global media coverage. It is followed by articles about environment, space, technology, physics and other areas. Armenian media mainly tends to focus on a scientific topic if at first sight it contains something revolutionary. Media primarily reviews whether that scientific study can affect the Armenian economy and only then decides to refer to it. Unfortunately, nowadays the perception of science is a little distorted in media. We can often see headlines of news where is mentioned that the scientist has made "an invention". Nowadays it is hard to see the border between a scientist and an inventor. In fact, the technological term "invention" attracts the media by making illusionary sensation and ensuring large audience. The report also addresses the "Gitamard" ("A science-man") special project started in 2016 in Mediamax that tells about scientists and their motivations.

    Youth media is emerging as an interdisciplinary field of practice and subject of study. Over the last two decades, there have been many efforts within communities to engage in media, especially within the fields of youth work and education. Despite the increase in practice, we found surprisingly little attention to the potential for youth media within the social work literature. Drawing on a qualitative content analysis of program descriptions from 49 youth media groups, the authors attempt to examine the current field of youth media. Using a critical media literacy framework, the authors analyze the practice of these youth media groups and apply those findings to social work practice, education, and research.

    Full Text Available The paper aims at providing an insight into media consumption among children in Serbia. A consumer survey was conducted to examine differences in children's consumption of various advertising media based on their age, gender and hometown. The research findings revealed significant differences between the two age cohorts in the three out of four tested media categories (TV, print, radio and Internet. On the other hand, the research findings also revealed variations in consumption of radio and print media, and no difference in the consumption of television and Internet between boys and girls. Finally, the research findings suggested significant differences in the consumption of Internet among children living in five cities in Serbia. Though the sample included more than 700 children it cannot be considered strictly representative for the whole country since the survey was conducted in urban areas only. However, the greatest value of this study comes from the fact that the research was placed in Serbia as a transitional society of the Western Balkans which has been seriously underrepresented in the main body of contemporary marketing theory and research studies. Therefore, one of the main goals of this paper was to make a contribution to better understanding of local conditions that might influence marketing decisions when communicating with children as a specific target group on Serbian market.

    Social media rapidly disseminates information but is a controversial learning platform in nurse education. This study aimed to explore how students viewed the use of Twitter, and other social media, in their first year of a nursing degree. The aim of this study was to evaluate first year student nurses' use of social media, before and after commencing a pre-registration programme, where Twitter was used in a module. A cross-sectional approach using a descriptive survey was completed. An online survey, that included Likert scale and open questions, was open for one month in 2016. All students on Nursing Undergraduate Degrees, in Adult, Child and Mental Health, who were in the first year of their programme were eligible to participate. 121 students took part with a response rate of 32%. Most students were positive about using social media as they found it an engaging way to promote discussion and share information. Students use of Twitter changed in the first year with 19.8% using it once or more per week on commencement of the programme which increased to 45.5%; other social media platforms remained static. Most students (57.8%) understood the purpose of using Twitter although 14% reported that it was not used within their module; thus, not all students gained experience of using the social media. 81% of students said that using Twitter had been beneficial to increase awareness of nursing issues within their course. However, there were areas that students found difficult such as time, and not knowing what to say. The study suggests that teaching about social media, and incorporating it into learning activities, may be beneficial for students. However, more research into the subject using an experimental design to assess changes over time would be useful. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Exploitation of women now comes in new faces; through the mass media. Media currently has a dual role, like two sides of a coin, on one side the media serves as a mediator for the improvement and progress of the nation, on the other side contributes to the suppression of media for the benefit of market capitalism toward consumer culture women once again being the subject of image construction. Expansion of the market and the mass media can not be separated from the flow of consumerism, because the mass media (particularly advertising on television is an extension of the market to boost sales of industrial products in the form of imagery that originates from the "mode of production". Through the process of meaning people are affected by the image created by the market and advertisement that increase their consumptive behavior. Here begins the role of advertising in blurring the identity as the supporting tool of consumerism, therefore those who identify themselves as modern men are no longer themselves but apparently no more than "Robot Man" impersonator without original identity, the principle of life pawned in the name of modernity. Women are vying to look beautiful, to buy up all whitening products, hair straightener tools, body slimming drugs, making them "Paranoid" who are restless because being haunted by old age. Actually they are aware of the exploitation, but enjoy it on the pretext of style and fashion. Key words: women, exploitation, mass media

    Cassidy, Angela

    2005-04-01

    This paper presents findings from quantitative analyses of UK press and print media coverage of evolutionary psychology during the 1990s. It argues that evolutionary psychology presents an interesting case for studies of science in the media in several different ways. First, press coverage of evolutionary psychology was found to be closely linked with the publications of popular books on the subject. Secondly, when compared to coverage of other subjects, a higher proportion of academics and authors wrote about evolutionary psychology in the press, contributing to the development of a scientific controversy in the public domain. Finally, it was found that evolutionary psychology coverage appeared in different areas of the daily press, and was rarely written about by specialist science journalists. The possible reason for these features are then explored, including the boom in popular science publishing during the 1990s, evolutionary psychology's status as a new subject of study and discussion, and the nature of the subject its as theoretically based and with a human, "everyday" subject matter.

  12. The Models and Politics of Mobile Media

    Directory of Open Access Journals (Sweden)

    Gerard Goggin

    2008-01-01

    Full Text Available In this paper I seek to critically evaluate the models at play in an important area of new media cultures -- mobile media. By 'mobile', I mean the new technologies, cultural practices, and arrangements of production, consumption, and exchange, emerging with hand-held, networked devices --especially those based on mobile cellular networks. These mobile phone technologies are now commonly being framed as media; and so we see the appearance of objects such as mobile television, mobile film, mobile games, and mobile Internet. This much-heralded move, with its large cultural and commercial claims, raises important theoretical and political questions. To zero in on what it at stake in the shift from mobile phone to mobile media, I consider three distinct though related models that for ease of reference I will term: phones; commons; publics. Firstly, I look at the model of the telephone (latterly, telecommunications that is still strongly influential in the shaping of mobiles as they now figure as media. This is something that is not widely recognised, however -- for instance, when mobiles as simply seen as an extension of new media cultures based on ideas formed through the experience of the Internet. Secondly, I consider the model of the commons and what light it throws on the politics of mobile media. Discussions of the commons -- for instance, the lucid work of Yochai Benkler in his 2006 The Wealth of Networks -- typically take the Internet as their paradigm example. But what how does the model of commons relate to mobiles, and what might it tell us about mobile media? Thirdly, while the telephone and mobile phone also have often been modelled through the concept of 'community', mobile media encourage us to think about the different and sometimes opposed model of publics. In drawing upon recent work on publics, what I am interested here is how new kinds of publics are emerging with mobile media.

In PE, just 2% were found in the Health section and nearly 70% in Culture and Society and General/Home News. Most of the articles were informative in nature and contained socio-political messages (90%. Statements by PC professionals were found in 35% of the articles and by politicians in 32%. The most frequent content was related to facing end of life (74% and patient quality of life (70%.The Spanish written media reflects the socio-political interest aroused by PC. Nevertheless, messages circulating about PC do not describe professional practice, or the contribution of the same for patients. Content more in line with the clinical practice might help contribute to the development of this new area of medicine.

  14. Media Activism as Movement? Collective Identity Formation in the World Forum of Free Media

    Directory of Open Access Journals (Sweden)

    Hilde C. Stephansen

    2017-09-01

    Full Text Available More than simply tools used by social movements to reach other substantive aims, media are increasingly becoming subjects of activism. This article contributes to advancing understanding of such media-focused activism through a case study of the World Forum of Free Media, a thematic forum for media activists and media advocacy organisations linked to the World Social Forum. Based on qualitative research conducted between 2008 and 2016—including participant observation, in-depth interviews and textual analysis—the article critically explores the extent to which the World Forum of Free Media can be considered a ‘free media’ movement in the making, and examines some of the challenges and contradictions that such a movement-building project entails. Drawing on social movement theory, specifically the concept of collective identity, it analyses efforts by forum organisers to mobilise a very diverse range of actors—from alternative media activists to policy- and advocacy NGOs—around a plural and inclusive ‘free media’ identity. While the World Forum of Free Media has to some extent succeeded in facilitating convergence around a set of core principles and ideas, it has so far struggled to develop a clear outwards-facing identity and mobilise a broad grassroots base.

    2017-12-01

    To review updates in how abortion care is depicted and analysed though various media outlets: news, television, film, and social media. A surge in recent media-related abortion research has recognized several notable and emerging themes: abortion in the news media is often inappropriately sourced and politically motivated; abortion portrayal in US film and television is frequently misrepresented; and social media has a new and significant role in abortion advocacy. The portrayal of abortion onscreen, in the news, and online through social media has a significant impact on cultural, personal, and political beliefs in the United States. This is an emerging field of research with wide spread potential impact across several arenas: medicine, policy, public health.

  20. Pervasive media violence.

    Science.gov (United States)

    Schooler, C; Flora, J A

    1996-01-01

    In this review, we focus our discussion on studies examining effects on children and young adults. We believe that the current epidemic of youth violence in the United States justifies a focus on this vulnerable segment of society. We consider media effects on individual children's behaviors, such as imitating aggressive acts. In addition, we examine how the media influence young people's perceptions of norms regarding interpersonal relationships. Next, we assess mass media effects on societal beliefs, or what children and adolescents think the "real world" is like. We suggest these media influences are cumulative and mutually reinforcing, and discuss the implications of repeated exposure to prominent and prevalent violent media messages. Finally, we catalog multiple intervention possibilities ranging from education to regulation. From a public health perspective, therefore, we evaluate the effects that pervasive media messages depicting violence have on young people and present multiple strategies to promote more healthful outcomes.

  2. Genre in media production

    Directory of Open Access Journals (Sweden)

    Hanne Bruun

    2011-08-01

    Full Text Available How do we explain changes in media genres? Are they the result of economic, technological or other kinds of structural forces; or are they the result of the change-producing agency of the media producers? And how are changes in media texts connected to contextual conditions for media production on micro-, meso- or macro levels? This article suggests that a theoretical approach using a pragmatic and socio-cognitive understanding of genre will help us to address these questions. This approach can highlight the interplay between human agency and different kinds of structural forces involved in specific professional media production cultures. Furthermore, it has the potential to integrate media texts and especially the micro- and meso levels of production. Using lessons learned and findings from my recent production study of Danish television satire, the article will argue three major methodological as well as knowledge-producing advantages of a genre approach.

    This paper aims to investigate the media industry in Asia, with reference to international standards of media tools, instruments, content, and coverage. We have also explored factors that may further improve Asian media. We have used an empirical approach. Our findings revealed that the media in Asian significantly contribute to expanding cultural knowledge and the exchange of multilateral dialogues. However, they do not look after the interests of minorities or non-dominating communities. Although the media should be a virtual ambassador, they often provoke hostilities within regions. Governments own most media outlets in the developing nations in Asia, and so the media rely on government backing and are subject to restrictions. International and national regulations connected to media freedom or constraints should be explored to protect Asian societies. The practical implications of these negative aspects are that the Asian media does not help the plights of minorities or minimize the fear of war in the region. The universal lesson of brotherhood among humanity for all colors and races should be preached by the media. In this paper, we have concentrated on how Asian media influence cultural expansion, the exchange of multilateral dialogues, the interests of minorities, aggression between nations, and generate income for common citizens.

    2012-06-01

    Pediatricians care for children's growth and development from the time they are born until they become adults. In addition, pediatricians must be vigilant for external influences. Technology influences children of all ages. Seventy-five percent of teenagers own cell phones, with 25% using them for social media. Technology can lead to an increase in skills and social benefits but there is also the potential for harm such as sexting, cyberbullying, privacy issues, and Internet addiction, all of which can affect health. Pediatricians must become well versed in the new media to provide media-oriented anticipatory guidance and advice on media-related issues. Copyright © 2012 Elsevier Inc. All rights reserved.

  8. Media multitasking in adolescence.

    Cain, Matthew S; Leonard, Julia A; Gabrieli, John D E; Finn, Amy S

    2016-12-01

    Media use has been on the rise in adolescents overall, and in particular, the amount of media multitasking-multiple media consumed simultaneously, such as having a text message conversation while watching TV-has been increasing. In adults, heavy media multitasking has been linked with poorer performance on a number of laboratory measures of cognition, but no relationship has yet been established between media-multitasking behavior and real-world outcomes. Examining individual differences across a group of adolescents, we found that more frequent media multitasking in daily life was associated with poorer performance on statewide standardized achievement tests of math and English in the classroom, poorer performance on behavioral measures of executive function (working memory capacity) in the laboratory, and traits of greater impulsivity and lesser growth mindset. Greater media multitasking had a relatively circumscribed set of associations, and was not related to behavioral measures of cognitive processing speed, implicit learning, or manual dexterity, or to traits of grit and conscientiousness. Thus, individual differences in adolescent media multitasking were related to specific differences in executive function and in performance on real-world academic achievement measures: More media multitasking was associated with poorer executive function ability, worse academic achievement, and a reduced growth mindset.

    2008-06-01

    The International Year of Astronomy New Media Working Group (IYA NMWG) has a singular mission: To flood the Internet with ways to learn about astronomy, interact with astronomers and astronomy content, and socially network with astronomy. Within each of these areas, we seek to build lasting programs and partnerships that will continue beyond 2009. Our weapon of choice is New Media. It is often easiest to define New Media by what it is not. Television, radio, print and their online redistribution of content are not New Media. Many forms of New Media start as user provided content and content infrastructures that answer that individual's creative whim in a way that is adopted by a broader audience. Classic examples include Blogs and Podcasts. This media is typically distributed through content specific websites and RSS feeds, which allow syndication. RSS aggregators (iTunes has audio and video aggregation abilities) allow subscribers to have content delivered to their computers automatically when they connect to the Internet. RSS technology is also being used in such creative ways as allowing automatically updating Google-maps that show the location of someone with an intelligent GPS system, and in sharing 100 word microblogs from anyone (Twitters) through a single feed. In this poster, we outline how the IYA NMWG plans to use New Media to reach target primary audiences of astronomy enthusiasts, image lovers, and amateur astronomers, as well as secondary audiences, including: science fiction fans, online gamers, and skeptics.

  13. Social media use for occupational lung disease.

    Harber, Philip; Leroy, Gondy

    2017-04-01

    Social media have great impact on all aspects of life throughout the world. The utilization of social media for occupational lung disease, however, has been much more limited. This article summarizes recent literature concerning social media for occupational lung disease and identifies areas for additional use. Social media are used in six relevant areas: information dissemination, peer-to-peer communication, survey research data collection, participatory research and exposome data acquisition, assessing public concerns, and knowledge generation. There are very clear advantages for information dissemination from experts to workers and on a peer-to-peer basis, although variable credibility and accuracy concerns persist. For research, social media have been used for acquiring data posted for nonresearch purposes and for efficiently collecting information specifically for research. The benefits of efficiency, democracy, and very large data sources may counterbalance concerns about inadequate specification of recruitment strategies and limited control over data quality. The potential benefits of using social media for lung health-workplace interactions are much greater than the very limited current utilization.

    This study uses the politics of global warming in the US to investigate an affective mechanism of hostile media perception and the democratic consequences of such perception, in an effort to delineate audience and journalistic barriers to stimulating urgent concern about climate change. The study confirms that partisanship played a significant role in perceptual differences with regard to media bias in an important area of science journalism--climate change. News consumers' anger perception was tested as a mediator in seeking an affective mechanism of hostile media perception. Hostile media perception has important democratic consequences in that it is positively associated with individuals' trust in news coverage of global warming and with selective media use.

    1990-01-01

    The International Energy Subject Thesaurus contains the standard vocabulary to indexing terms (descriptors) developed and structured to build and maintain energy information databases. Involved in this cooperative task are (1) the technical staff of the USDOE Office of Scientific and Technical Information (OSTI) in cooperation with the member countries of the Energy Technology Data Exchange (ETDE) and (2) the International Nuclear Information System (INIS) staff representing the more than ninety countries and organizations recording and indexing information for the international nuclear information community. ETDE member countries are also members of the International Nuclear Information System (INIS). Nuclear information indexed and recorded for INIS by these ETDE member countries is also included in the ETDE Energy Data Base, and indexing terminology is therefore cooperatively standardized for use in both information systems. This structured vocabulary reflects the scope of international energy research, development, and technological programs and encompasses terminology derived not only from the basic sciences but also from the areas of energy resources, conservation, safety, environmental impact, and regulation.

    Full Text Available The development of digital media has brought a new challenge to existing science popularization in the rural areas. In this paper, new experience of rural science popularization on both traditional and digital media in Zhejiang province was introduced. We proposed several strategies for rural science popularization in the digital media era: First, we should strengthen the utilization of traditional platforms such as print media and broadcast and TV media. Then, digital media based on Internet should also be used for science popularization. Last but not least, we should also try to use “the fifth media” to upgrade existing platforms and create new Internet media channels.

    1998-07-01

    In May 1998, representatives of Japan's mass media toured Bangladesh to learn about the country's reproductive health and population programs. The goal of the visit was for the journalists to spread information about the projects to their peers, to government officials, and parliamentarians responsible for allocations of foreign aid. The 1st stage of the visit involved meetings with program officials and organizers. In the 2nd stage, the journalists toured: 1) Matlab, where the International Center for Diarrhoeal Disease Research has been implementing an intensive family planning (FP) program; 2) the Panchdona IP area, where the Integrated Family Development Project is being conducted with funding from the Japanese government; 3) an FP office and satellite clinic; and 4) a site where voluntary organizations are providing FP/maternal-child health care. The journalists also learned about how micro-credit loans operate. Participating journalists reported that they were very impressed with the people of Bangladesh, and that they had gained a new understanding of the relationship between reproductive health and human rights.

    Taubert, Mark; Watts, Gareth; Boland, Jason; Radbruch, Lukas

    2014-03-01

    The uses of social media have become ubiquitous in contemporary society at an astonishingly fast-paced rate. The internet and in particular platforms such as Facebook, Twitter and YouTube are now part of most people's vocabulary and are starting to replace many face-to-face interactions. The online world, in particular, is alive with discussions, comments and anecdotes about the topics of illness, disease, hospitals, death and dying. The topic of death and dying had in the not too distant past been seen as taboo, but willingness and need to talk openly about it appears to be on the increase. In parallel to this, many public awareness campaigns are highlighting society's need to be more prepared for dying and death. This will have a significant impact on the way terminally ill patients and their families approach the last years, months and weeks of their lives and how they might expect palliative health and social care professionals working with them through these difficult periods to interact with them. We pay particular attention to the areas of digital posterity creation and memorialisation within the wider holistic context of end-of-life care.

    2017-09-01

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

  1. Psychological reality of cross-media artistic styles.

    Science.gov (United States)

    Hasenfus, N; Martindale, C; Birnbaum, D

    1983-12-01

    The sensitivity of artistically naive people to cross-media styles (baroque, neoclassic, and romantic) and to period styles (works composed by artists born during the same epoch) in four media (painting, poetry, music, and architecture) was assessed. In two studies, adult subjects tended spontaneously to sort stimuli according to both cross-media styles and period styles. In a third study, nursery school children were shown to be able to sort pictures of paintings and architectural facades on the basis of cross-media styles. Other experiments using rating scales again demonstrated that artistically naive adults are sensitive to both cross-media styles and period styles even when they are not implicitly urged to disregard medium. These and other studies using rating scales suggested that the bases for discrimination of both cross-media styles and period styles are the dimensions of realistic versus unrealistic and of overall arousal potential.

    Full Text Available ABSTRACT. Studying in a foreign country provides an opportunity for students from diverse cultural backgrounds to develop an intercultural friendship between each other. In today’s increasingly digitalized society, the use of social media cannot be detached from any communication context, including intercultural communication. Previous studies have examined the use of social media in various settings of intercultural communication. This study aims to examine the use of social media in intercultural friendship development among foreign students in Kocaeli University, Turkey. Applying qualitative method, six foreign students who represent four different cultural backgrounds were interviewed in this study. The interview tried to explore their subjective experiences of using social media to develop an intercultural friendship with other foreign students in their surroundings. The study reveals various similarities and differences of the pattern, evaluation, and impact of using social media in intercultural friendship development. The study concludes that the use of social media tends to enhance the intercultural friendship development.

  12. Agricultural extension and mass media.

    Science.gov (United States)

    Perraton, H

    1983-12-01

    To learn more about the use of the mass media for agricultural extension, the World Bank has considered the efforts of 2 units: INADES-formation in West Africa and the Extension Aids Branch of Malawi. The INADES-formation study focuses on Cameroon but also considers work in Rwanda and the Ivory Coast. Some general conclusions emerge from a comparison of the 2 organizations. Malawi operates an extension service which reaches farmers through extension agents, through farmer training centers, and through mass media. The Extension Aids Branch (EAB) has responsibility for its media work and broadcasts 4 1/2 hours of radio each week. Its 6 regular radio programs include a general program which interviews farmers, a music request program in which the music is interspersed with farming advice, a farming family serial, and a daily broadcast of agricultural news and information. The 17 cinema vans show some agricultural films, made by EAB, some entertainment films, and some government information films from departments other than the ministry of agriculture. EAB also has a well-developed program of research and evaluation of its own work. INADES-formation, the training section of INADES, works towards social and economic development of the population. It teaches peasant farmers and extension agents and does this through running face-to-face seminars, by publishing a magazine, "Agripromo," and through correspondence courses. In 1978-79 INADES-formation enrolled some 4500 farmers and extension agents as students. Both of these organizations work to teach farmers better agriculture techniques, and both were created in response to the fact that agricultural extension agents cannot meet all the farmers in their area. Despite the similarity of objective, there are differences in methods and philosophy. The EAB works in a single country and uses a variety of mass media, with print playing a minor role. INADES-formation is an international and nongovernmental organization and its

    1992-07-01

    The media information review, requested by the Communications Subcommittee of the Technical Steering Panel (TSP), provides a general indication of the media`s areas of interests with regard to the Hanford Environmental Dose Reconstruction (HEDR) Project. This review briefly assesses 14 newspaper articles/advertisements collected between January and June 1992 by Battelle Pacific Northwest Laboratories (BNW). Articles that mention the project, activities closely associated with it, or members of the Panel were included in the analysis. The sources of the articles and announcements include most newspapers in the Northwest (dailies and weeklies) as collected and distributed to the US Department of Energy (DOE) and Hanford contractors by Westinghouse Hanford Company, Communications. National and international media coverage was provided during the review period by Burrelle`s Press Clipping Service, New York, and A.T.P., New Jersey. The articles and advertisements represent those collected and judged applicable to issues and activities associated with the Technical Steering Panel and the Hanford Environmental dose Reconstruction Project. The collection is not considered inclusive of every written account of the subject, but as good a representative collection as reasonable. This review is unscientific and is not meant to display a technical analysis of the materials.

  16. Long-Term Metal Retention Performance of Media Filter Drains for Stormwater Management

    2015-03-01

    Full Text Available Stormwater runoff, a substantial source of nonpoint pollution, can be treated using Best Management Practices (BMPs, such as the Media Filter Drain (MFD. An MFD is a trench filled with an engineered media mix, usually with a grass overlay, that receives runoff from the paved roadway next to it. The MFD was shown to remove dissolved metals (zinc and copper, typical pollutants from vehicles and urban areas, which might negatively impact aquatic species in receiving waters, but its long-term effectiveness was not known. Existing media filter mixes of different ages were collected from two different sites in the Pacific Northwest of the United States. Columns made with these media mixes received concentrated copper and zinc loading to simulate accelerated aging for estimated total lifespans from 14 to 22 years of copper and zinc loading, with little or no decrease in sorption. Throughout the aging process, some columns were subjected to performance testing with higher levels of typical runoff concentrations and average concentration decreases from influent to effluent were found to be greater than 90% for both copper and zinc. Based on this study, the MFD’s lifespan for zinc and copper treatment is significantly greater than the initial ten-year estimate.

  17. Appropriation of social media for fostering effective tacit knowledge sharing: developing conceptual model

    Science.gov (United States)

    Amidi, A.; Jabar, M.; Jusoh, Y. Y.; Abdullah, R.

    2017-09-01

    With the rising popularity of social media in the past few years, several researches ratiocinate that this type of interactive and collaborative technology could be a beneficial tool for the sharing of tacit knowledge. Nevertheless, very few literatures have tackled the subject of how social media could facilitate tacit knowledge sharing among medical practitioners, and what are its contributions in the area. Thus, the factors that drive individuals to share tacit knowledge need to be investigated further and included in literature. Through a systematic literature review, this study proposes seven enabling conditions which could potentially facilitate the sharing of tacit knowledge. TAM was applied as a novelty in this study in investigating the factors influencing knowledge sharing via social media, whilst taking into account the mediation effects of Attitude in social media usage. This study uncovered an important correlation between virtual settings and the conversion of tacit knowledge, which affects organizational members who are not co-located physically but have a crucial need for sharing information.

    2013-01-01

    The subjective feeling of free choice is an important feature of human experience. Experimental tasks have typically studied free choice by contrasting free and instructed selection of response alternatives. These tasks have been criticised, and it remains unclear how they relate to the subjective feeling of freely choosing. We replicated previous findings of the fMRI correlates of free choice, defined objectively. We introduced a novel task in which participants could experience and report a graded sense of free choice. BOLD responses for conditions subjectively experienced as free identified a postcentral area distinct from the areas typically considered to be involved in free action. Thus, the brain correlates of subjective feeling of free action were not directly related to any established brain correlates of objectively-defined free action. Our results call into question traditional assumptions about the relation between subjective experience of choosing and activity in the brain’s so-called voluntary motor areas. PMID:24021855

  2. The Greek media and the Kosovo crisis

    Directory of Open Access Journals (Sweden)

    Margarita Kondopoulou

    2002-10-01

    Full Text Available The NATO air attacks (24/3/99-10/6/99 as an instrument of force against Serbia to terminate the abuse of the Albanian population in Kosovo, albeit supported by a significant part of the international community, were received much differently in Greece. Key to the climate of strong disagreement with the campaign was the role of the Greek media. The true reason behind the offensive was, according to them, the change in the geopolitical map to the advantage of the West, and in particular the USA. The underlying argument of this paper is that in the Kosovo crisis the media, Greek (and international, projected their own environment. It is particularly apt to examine the Greek case because of its very unique perspective that differentiated the coverage in Greece - a NATO member country - from the overall world media view. Also, the discussion is pertinent because Greek media coverage disagreed with the official government position, which although advocating a diplomatic resolution of the crisis, had to support the Alliance's decision to bomb Serbia. Furthermore, study of this case is significant because the clash of the Greek media view with the mainstream pro-NATO coverage found in many other countries generated negative views on Greece and its media on the international level. An examination of media content reveals that despite any differences concerning political or other factors, and regardless of the variations in the phrasing of the anti-NATO arguments, the overall media perspective exhibited a unanimous opposition to the bombing campaign. By placing the emphasis more or less on the same thematic areas as the world media, but by crucially reversing the line of reasoning (e.g. the refugee problem was blamed on the NATO bombing raids and not on Serbian atrocities, the Greek media invariably remained anti-war, anti-NATO and anti-Albanian in many particular cases, and in principle pro-Serb throughout.

Because of the pervasive influence the media has on marketing success, sport marketers must make concerted efforts to create a positive relationship between their sport event and the media. They may accomplish this by providing the media with press releases, having news conferences, having media-day events (in which the media are invited to interact with the players, coaches, and administrators, providing media guides for the respective sport events and so on. Each of these activities promotes active involvement from the media, which will subsequently contribute to relationship building with the community.

  18. Media multitasking and implicit learning.

    Science.gov (United States)

    Edwards, Kathleen S; Shin, Myoungju

    2017-07-01

    Media multitasking refers to the simultaneous use of different forms of media. Previous research comparing heavy media multitaskers and light media multitaskers suggests that heavy media multitaskers have a broader scope of attention. The present study explored whether these differences in attentional scope would lead to a greater degree of implicit learning for heavy media multitaskers. The study also examined whether media multitasking behaviour is associated with differences in visual working memory, and whether visual working memory differentially affects the ability to process contextual information. In addition to comparing extreme groups (heavy and light media multitaskers) the study included analysis of people who media multitask in moderation (intermediate media multitaskers). Ninety-four participants were divided into groups based on responses to the media use questionnaire, and completed the contextual cueing and n-back tasks. Results indicated that the speed at which implicit learning occurred was slower in heavy media multitaskers relative to both light and intermediate media multitaskers. There was no relationship between working memory performance and media multitasking group, and no relationship between working memory and implicit learning. There was also no evidence for superior performance of intermediate media multitaskers. A deficit in implicit learning observed in heavy media multitaskers is consistent with previous literature, which suggests that heavy media multitaskers perform more poorly than light media multitaskers in attentional tasks due to their wider attentional scope.

We need to analyze how different actors and organizations see and think about technology, the forms of knowledge that people draw on as they make sense of, develop, and use social media. Central among these is bullshit. This short essay discusses bullshit as defined by the philosopher Harry Frankfurt as statements made with little or no concern for their truth-value or justification and argues that social media are accompanied by unusually large amounts of bullshit for two reasons. First, they confront us with epistemological problems and are hard to understand. Second, there is a large demand for knowledge about what they mean, a powerful political economy that generates a lot of statements about social media, including substantial amounts of bullshit. Given the rapid development of social media and their growing importance, this is unlikely to change in the near future. Bullshit is here to stay, and we need to take it seriously intellectually and analytically to understand social media.
