The Question of Culture Consumption and Stratification Revisited

While the question of whether there exists a connection between social stratification and lifestyle differentiation seems to be uncontroversial, the primary issue that continues to bedevil research at the intersection of the sociology of culture and the study of structured inequality, concerns the precise nature of this connection. While various answers have been proposed to this question, the current state of the field is one of “ambiguity” as to what is the best way to proceed. In this paper, I use a long-term historical perspective to tackle this question. I argue that understanding the cultural stratification system that appears to have coalesced in the richer societies of the contemporary Global North, we must attend to the historical origin and trajectory of the system of production of symbolic goods in the West, and how this has interacted with the system of scholastic “production” of consumers of such goods. This system can best be described as an embodied cultural capital regime, in which the ability to indirectly decode the formal properties of cultural goods using habitualized schemes of perception and appreciation has replaced the capacity to directly acquire cultural works through purchase as the primary marker of status.
Lawrence Berkeley National Laboratory Recent Work Title A subleading operator basis and matching for gg → H Permalink

The Soft Collinear Effective Theory (SCET) is a powerful framework for studying factorization of amplitudes and cross sections in QCD. While factorization at leading power has been well studied, much less is known at subleading powers in the λ 1 expansion. In SCET subleading soft and collinear corrections to a hard scattering process are described by power suppressed operators, which must be fixed case by case, and by well established power suppressed Lagrangians, which correct the leading power dynamics of soft and collinear radiation. Here we present a complete basis of power suppressed operators for gg → H, classifying all operators which contribute to the cross section at O(λ2), and showing how helicity selection rules significantly simplify the construction of the operator basis. We perform matching calculations to determine the tree level Wilson coefficients of our operators. These results are useful for studies of power corrections in both resummed and fixed order perturbation theory, and for understanding the factorization properties of gauge theory amplitudes and cross sections at subleading power. As one example, our basis of operators can be used to analytically compute power corrections for N -jettiness subtractions for gg induced color singlet production at the LHC.
Association Rule Hiding for Privacy Preserving Data Mining : A Survey on Algorithmic Classifications

The increased collection, storage and analysis of personspecific data cause serious challenges to the protection of the identities to which such data correspond. In various conditions, the extracted knowledge is highly confidential and it needs to be sanitized before published in order to address privacy concerns. Data mining technology is capable of extract huge amount of knowledge with minimal time period. The knowledge extracted by intelligent data mining algorithm may reveal most sensitive information belongs to a person or an organization. Data belongs to a person or an organization may have different sensitive levels. These data are made available only for authorized persons. So ensuring the protection of sensitive data by access restriction is not a complete method. This may affect the utility of the data mining result and with help of the knowledge the user may reidentify sensitive data items from non-sensitive data is known as ‘Inference Problem’. The privacy preserving data mining is to provide a solution for protecting sensitive information by developing a data mining techniques which could be applied on databases without affecting the accuracy of data mining result. At the same time without violating the privacy of individuals. This paper states a detailed study on various algorithms for association rule hiding methods.
Generic Analysis of E-voting Protocols by Simplified Blockchain

Upon blockchain technology gains popularity, lots of attempts have been made to adopt this into all ICT systems. One notable example is to apply blockchain to e-voting protocols. However, careful analysis on the requirements and side effects should be scrutinized before the adoption of the new technology. We analyze whether blockchain-based e-voting protocols still satisfy their security requirements, by deriving generic transformations from blockchain-based e-voting protocols to classical e-voting protocols, while preserving the knowledge set for the public. Compared to classical e-voting protocols, we claim that blockchain-based e-voting protocols have generically weaker confidentiality and generically stronger universal verifiability, judged by the point of our generic analysis.
A CLEANING METHOD BASED ON THE USE OF AGAR GELS: NEW TESTS AND PERSPECTIVES

For the peculiar artworks such as stucco plasterworks cleaning is troublesome for different reasons: weak mechanical behavior, high porosity and resulting water absorption, partial water solubility in the case of gypsum plaster. The choice of the cleaning method, especially as concerns gypsum based stucco materials, is crucial in assuring the lowest harmfulness possible together with a good level of efficacy. With the term agar we name a powder product composed mainly of polysaccharides and extracted from red algae species. When boiled with water, in a percentage range in between 0.5 and 5, it produces a colloidal solution that gellifies towards 35 °C. It can be used gelified and cold placed on a plan stucco surface, tepid and fluid poured on a surface relief or otherwise milled till a snow consistency, then pressed as a pad onto any surface; it has a high content of water which is slowly released into the porous substrate system. Hence the water-soluble components of soiling present on the surface are extracted and removed with the gel. Conservators should tune the following parameters to adjust the cleaning mode to a specific situation: agar powder concentration in water, application method (gel, tepid solution, “milled”) and contact time. At the moment, agar gel is successfully used in cleaning gypsum plaster objects with grey coherent soiling deposits. In our study agar was used in cleaning a dolostone capital. The power of agar in extraction of soluble salts was compared for different application methods and concentrations. The ions in the gel were analyzed with the aid of IC (Ionic Chromatography) and ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry).
Soft Keyboard Evaluations: Integrating User’s Background in Predictive Models

Predictive models, based on cognitive and motor laws (modeling some aspect of human behaviors), were supposed to provide an efficient tool to compare quickly soft keyboards performances, but these models are confronted with some limits. Moreover, they failed to predict efficiently the performances during the first usage that got an important impact on soft keyboard acceptability. To improve these models, the authors integrated into them the character search strategies oriented by the user’s background. They illustrate their purpose by modeling three keyboards and comparing the results with experimental ones. The models integrating the user’s background predicted results close to the experimental ones. However, those models must be adapted to the function of the keyboard and the targeted population. The applicability of the models as a rapid comparison tool for soft keyboards must be questioned.
Phenotypically Induced Intraspecific Variation in the Morphological Development of Wetland and Stream Galaxias gollumoides McDowall and Chadderton

The hypothesis that contrasting hydrology induces divergent intraspecific phenotypic plastic responses in non-migratory freshwater fish was investigated. Morphologies of wetland and stream Galaxias gollumoides from South Island, New Zealand, at different stages of ontogeny, were examined. Phenotypic responses were tested for in a 2 × 2 factorial laboratory based controlled reciprocal transplant experiment with flow (current or no current) and source habitat (wetland or stream), as treatments. There was a shift in the overall head morphology of wetland current treatment G. gollumoides away from the wetland no current treatment, and toward the stream current treatment, demonstrating convergence in head morphology in the presence of flow of wetland and stream sourced captive G. gollumoides. Morphologies of captive reared G. gollumoides were also compared to developmental trajectories of morphological characters during the ontogeny of field reared first year, and adult conspecifics. In combination, experimental and field results support the hypothesis, finding habitat hydrology to be the potential mechanism inducing and maintaining intraspecific morphological divergence in G. gollumoides. Recognition of this mechanism inducing morphological divergence between populations also aids the taxonomic description of long genetically recognised lineages of co-members of the Galaxias vulgaris species complex.
Dental Implant Bioactive Surface Modifiers: An Update

Objectives: Main purpose of this review was to present an update on various coating materials utilized in improving the surface chemistry of the dental implants. Methods: Literature search was carried out in various on-line databases such as PubMed, Medline, Google scholar, EBSCO, Wiley Science Library, and Saudi Digital Library using appropriate keywords (dental implant surface coatings, dental implant surface modifiers, and dental surface coatings). Results: Total of 569 studies were retrieved. All the relevant studies among them were reviewed and compiled. Conclusion: Current implant surface's biomimetic coatings offer many benefits compared to the traditional plasma sprayed coatings. Further incorporation of biomimetic coatings with various material has lead improvement in mechanical and biological properties of implants.
Examining Recovery Program Participants by Gender: Program Completion, Relapse, and Multidimensional Status 12 Months After Program Entry

This study examined individual-level characteristics and factors associated with program completion, relapse, and multidimensional status at follow-up for 213 men and 248 women who entered one of 17 peer-led recovery programs and who completed a follow-up interview 12 months later. Study results found that although there were some significant gender differences at program entry among participants entering Recovery Kentucky, there were few gender differences at follow-up. In addition, although participants had significant psychosocial problems, polysubstance use patterns, and severe substance use disorder (SUD), the majority of both men and women reported completing the program (80.3%), a small minority reported relapse (9.5%), and about one third had worse multidimensional status about 12 months after program entry. Lower quality of life rating at program entry was associated with program completion and with better multidimensional status at follow-up. Study results suggest the recovery program provides an important option for some of the most vulnerable individuals with SUD.
Three-Dimensional Assessment of the Oral Health-Related Quality of Life Undergoing Fixed Orthodontic Therapy

Aims and Objectives: Discomfort associated with the use of fixed orthodontic appliances may have a negative influence on the patient's oral health-related quality of life (OHRQoL). In general, OHRQoL assessments have the potential to provide information on the need to improve the overall quality of care. This study aims to assess the impact of fixed orthodontic appliances on OHRQoL of Saudi population and to explore the impact of the patient's gender and age on perceived treatment. Subjects and Methods: This cross-sectional study used a generic measure of OHRQoL the Arabic version of the Oral Health Impact Profile (OHIP-14), which is a responsive measure to changes in oral health conditions. Data were collected using self-completed e-questionnaire which was distributed through social media and were analyzed using Statistical Package for Social Sciences (SPSS) version 21.0. Results: A total of 149 subjects, 110 (73.8%) were females and 39 (26.2%) were males. Adolescents between 13 and 20 years were 63 (42.3%) and adults between 21 and 30 years were 86 (75.7%). A response rate of 100% was obtained. The prevalence of oral health impacts according to OHP-14 was 22.5%. OHIP-14 consists of 14 items covering seven domains. A three-dimensional structure was used to test the existence of separate dimensions: functional limitation, pain discomfort, and psychosocial impact. A significant difference was found between males and females in the first dimension (P = 0.038) and the third dimension (P = 0.022). In addition, a significant difference was also found between the two age groups included in the study within the third dimension (P = 0.025). Conclusion: Fixed orthodontic appliances had an evident impact on OHRQoL. However, males had significantly altered functional limitations while females had a higher psychological impact. Furthermore, adults had a significantly higher psychological impact than adolescents.
A Clinical and Radiographic Evaluation of Resonance Frequency Analysis of Sand Blasted Acid Etched (SAE) and Chemical Modified Sae Dental Implants

Aims and Objective: Chemically modified and sandblasted acid-etched (SAE) mechanism leads to wettability of surfaces of dental implants which helps in osseointegration. The present study was conducted to determine the implant stability quotient (ISQ) of SAE and SAE chemically modified dental implants. Materials and Methods: The present study was conducted on 210 patients with 120 males and 90 females. Dental implants (Adin) with SAE (Group A) and SAE chemically modified (Group B) were inserted in patients. RFA was done immediately after implant insertion and after 1 week, 2 weeks, 6 weeks, 10 weeks, and 14 weeks. Results were statistically evaluated using SPSS Statistics for Windows, Version 21.0, IBM Corp., Armonk, NY, USA. Results: Maximum patients were in the age group of 25–35 years (males – 65, females – 48), followed by 35–45 years (males – 40, females – 32) and 45–55 years (males – 15, females – 10). Maximum dental implants were given in the right side (88) in males than females (56). On the left side, maximum implants were given in females (62) than males (56). Maximum RFA value of 86.2 and minimum value of 44.6 were observed in SAE dental implants (A). The maximum mean RFA value in chemically modified implants SAE (B) was 89.4 and minimum was 32.5. Conclusion: It was observed that surface treatment of dental implants shows higher implant–bone osseointegration. There is fastest osseointegration in implants with hydrophilic surfaces than those with SAE surfaces. ISQ was higher than 75 in both groups, which indicate higher implant stability.
Pain neuroscience education on YouTube

Objectives The Internet in general, and YouTube in particular, is now one of the most popular sources of health-related information. Pain neuroscience education has become a primary tool for managing persistent pain, based in part on the discovery that information about pain can change pain. Our objective was to examine the availability, characteristics, and content of YouTube videos providing pain neuroscience education. Methods We conducted a systematic review of videos on YouTube using the search terms “pain education”, “what is pain”, and “pain brain” in January 2018. Videos were included if they were in English, were under 10 minutes long, and included information on the neuroscience of pain. Videos were coded for i) descriptive characteristics (e.g., number of views, duration on YouTube), ii) source and style, iii) whether or not they addressed seven pre-determined target concepts of pain neuroscience education (e.g., ‘Pain is not an accurate marker of tissue state’), and iv) how engaging they were. Results We found 106 unique videos that met the inclusion criteria. The videos ranged from having four views to over five million views (Mdn = 1163 views), with the three most highly viewed videos accounting for 75% of the total views. Animated videos were much more highly viewed than non-animated videos. Only a small number of videos had been posted by a clearly-identifiable reputable source such as an academic or medical research institution (10%), although a number of videos were posted by healthcare professionals and professional medical societies. For a small number of videos (7%), the source was unclear. We found 17 videos that addressed at least one target concept of pain neuroscience science education, only nine of which were considered to be engaging. The target concept ‘Pain is a brain output’ was considered to be well addressed by the most videos (N = 11), followed by ‘Pain is a protector’ (N = 10). We found only one video that adequately addressed all seven target concepts of pain neuroscience education. Discussion YouTube contains a variety of videos that practitioners, patients, and families may view to access pain neuroscience education information. A small portion of these videos addressed one or more target concepts of pain neuroscience education in an engaging manner. It is yet to be determined to what extent patients are able to learn information from these videos, to what extent the videos promote behavior change, and thus to what extent the videos may be useful for clinical practice.
Sheared phase-separating binary mixtures with surface diffusion

The phase-separation process of a binary mixture with order-parameter-dependent mobility under shear flow is numerically studied. The ordering is characterized by an alternate stretching and bursting of domains which produce oscillations in the physical observables. The amplitude of such modulations reduce in time when the mobility vanishes in the bulk phase, disfavoring the growth of bubbles coming from bursted domains. We propose two equations for the typical sizes Rx and Ry of domains finding the long-time behaviors Rx ∼ t5/4 and Ry ∼ t1/4 in the flow and shear directions, respectively, in the case of surface diffusion. A reduction of the excess viscosity with increasing shear rate is observed in simulations.
Reduced-order models for radiative heat transfer of hypersonic vehicles

Aerothermoelastic analysis of hypersonic vehicles is a complex multidisciplinary coupling problem. Thus, accurate modeling of varying disciplines with low computational cost is necessary. This work developed a tractable approach-based reduced-order modeling technology to solve the radiative thermal transfer problem in a hypersonic simulation. A method that combines proper orthogonal decomposition and unassembled discrete empirical interpolation method is developed to construct the reduced-order modeling. First, high-dimensional original systems are projected on the optional basis generated by proper orthogonal decomposition, and the nonlinear term is further approximated by unassembled discrete empirical interpolation method. Then, a numerical integration method for the solution of the reduced system of nonlinear differential equations is provided. Case studies that use a classical hypersonic control surface model, in which the time history and spatial distribution of the thermal load are known a priori, are conducted to validate the accuracy and efficiency of the reduced-order modeling methodology and to assess the robustness of the reduced-order modeling for thermal solution. Results indicate the ability of reduced-order modeling to reduce the nonlinear system size with reasonable accuracy.
The Chemical State and Occupancy of Radiogenic Pb, and Crystallinity of RW-1 Monazite Revealed by XPS and TEM

Monazite ((Ce, La, Nd, Th)PO4) is one of the widely used minerals for U–Th–Pb dating in geochronology. To better understand the possible effects of radiogenic Pb on the in situ dating method, a natural monazite U–Th–Pb standard sample (RW-1) was chemically and structurally characterized down to atomic scales by using the combination of Raman spectrum (RM), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The experimental results revealed that radiogenic Pb exists as Pb2+ and substitutes for the Ce site in the monazite crystal lattice. Moreover, TEM imaging demonstrated that monazite is well crystalline revealed by an atomic structure in most areas except for a few tiny defects, which are likely attributed to alpha self-healing from an electronic energy loss of α particles. The characterization of the chemical state and occupancy of radiogenic Pb, and the distribution of Pb and Th in monazite at the nanoscale and atomic scale could provide insight for us to understand the mechanisms of the nanogeochronology.
TrueView: A LIDAR Only Perception System for Autonomous Vehicle (Interactive Presentation)

Real time perception and understanding of the environment is essential for an autonomous vehicle. To obtain the most accurate perception, existing solutions propose to combine multiple sensors. However, a large number of embedded sensors in the vehicle implies to process a large amount of data thus increasing the system complexity and cost. In this work, we present a novel approach that uses only one LIDAR sensor. Our approach enables reducing the size and complexity of the used machine learning algorithm. A novel approach is proposed to generate multiple 2D representation from 3D points cloud using the LIDAR sensor. The obtained representation solves the sparsity and connectivity issues encountered with LIDAR-based solution. 2012 ACM Subject Classification Computing methodologies → Computer vision representations
Developing operational problem solvers: the role of job design decisions

To pursue continuous improvement, organisations must overcome numerous operational problems. To avoid these problems recurring, employees adopt a problem-solving orientation (PSO) behaviour to search for the underlying causes of problems and find the most adequate solution. Despite the importance of PSO in generating continuous improvement, past research has scarcely investigated the drivers of PSO. The purpose of this paper is to identify whether and how job design decisions related to task routinisation, job complexity, and job autonomy affect PSO. Drawing on data from 238 front-line employees of 23 manufacturing plants, multilevel regression models are used to test the research question. Results show that task routinisation and job complexity are positively associated with PSO whereas job autonomy is negatively associated with PSO. Moreover, job autonomy positively moderates the relationship between task routinisation and PSO whereas job complexity negatively moderates the relationship between task routinisation and PSO. In terms of managerial contributions, findings suggest that managers might develop PSO behaviours by involving employees in stable, standardised, and repetitive tasks (that generate high task routinisation) and making them perform complex tasks.
