A techno-sociological solution for designing a museum guide robot: Regarding choosing an appropriate visitor

In this paper, we present our work designing a robot that explains an exhibit to multiple visitors in a museum setting, based on ethnographic analysis of interactions between expert human guides and visitors. During the ethnographic analysis, we discovered that expert human guides employ some identical strategies and practices in their explanations. In particular, one of these is to involve all visitors by posing a question to an appropriate visitor among them, which we call the “creating a puzzle” sequence. This is done in order to draw visitors' attention towards not only the exhibit and but also the guide's explanation. While creating a puzzle, the human guide can monitor visitors' responses and choose an “appropriate” visitor (i.e. one who is likely to provide an answer). Based on these findings, sociologists and engineers together developed a guide robot that coordinates verbal and non-verbal actions in posing a question or “a puzzle” that will draw visitors' attention, and then explain the exhibit for multiple visitors. During the explanation, the robot chooses an “appropriate” visitor. We tested the robot at an actual museum. The results show that our robot increases visitors' engagement and interaction with the guide, as well as interaction and engagement among visitors.
A General Framework for Information Leakage

Consider a setting where a dataset needs to be shared or published for a specific set of learning tasks. For a given publishing, the maximal α-leakage quantifies an estimate of the adversary’s ability to learn any (potentially randomized) function of the original data from the published data. The choice of α (ranging from 1 to ∞) captures the adversary’s varying ability to refine its posterior belief about the original data with α = 1 capturing a purely belief-refining adversary and α = ∞ capturing an adversary that guesses the best posterior. Varying α allows continuous interpolation between the two extremes. For α = 1 the leakage introduced simplifies to mutual information and for α = ∞ it simplifies to maximal leakage. Several properties of this measure are proven; these include: (i) convexity in the privacy mechanism (maps original to published dataset); (ii) data processing inequality; and (iii) a composition property. Finally, the privacy-utility trade-off under a novel hard distortion constraint as well as Hamming distortion are developed.
Temporal Extent for Global Change Research Databases

We propose temporal extent, a concept that can be used to produce summary or abstracted information about the values of temporal attributes in a database relation or class of objects. In its simplest form, the temporal extent is a one-dimensional interval representing the minimum and maximum time points of the instances in a class. More generally, a set of temporal intervals are used to capture the temporal coverage of a set of temporal objects or class. The summary provides information about the class in a compact form that can be used concurrently with statistical abstraction mechanisms for approximate query answering and for fast browsing.
Segregación residencial de los extranjeros en el área metropolitana de Madrid. Un análisis cuantitativo

This article aims at fulfilling three objectives. First of all, stress the importance of neighbourhoods for individual life outcomes, by way of their relationship with other relevant spaces of socialization and with social exclusion processes. Secondly, measure immigrants’ residential segregation in Madrid’s Metropolitan Area, in four of the five dimensions proposed by Denton and Massey (1988), together with other measures less frequently used.
Optimization of Biological Synthesis of Silver Nanoparticles using Fusarium oxysporum

Silver nanoparticles are increasingly used in various fields of biotechnology and applications in the medicine. Objectives of this study were optimization of production of silver nanoparticles using biotransformations by Fusarium oxysporum, and a further study on the location of nanoparticles synthesis in this microorganism. The reaction mixture contained the following ingredients (final concentrations): AgNO3 (1-10 mM) as the biotransformation substrate, biomass as the biocatalyst, glucose (560 mM) as the electron donor, and phosphate buffer (pH= 7, 100 mM). The samples were taken from the reaction mixtures at different times, and the absorbance (430 nm) of the colloidal suspensions of silver nanoparticles hydrosols was read freshly (without freezing) and immediately after dilution (1:40). SEM and TEM analyses were performed on selected samples. The presence of AgNO3 (0.1 mM) in the culture as enzyme inducer, and glucose (560 mM) as electron donor had positive effects on nanoparticle production. In SEM micrographs, silver nanoparticles were almost spherical, single (25-50 nm) or in aggregates (100 nm), attached to the surface of biomass. The reaction mixture was successfully optimized to increase the yield of silver nanoparticles production. More details of the location of nanoparticles production by this fungus were revealed, which support the hypothesis that silver nanoparticles are synthesized intracellularly and not extracellularly.
Early lymphocyte expansion is severely impaired in interleukin 7 receptor-deficient mice

Interleukin 7 (IL-7) stimulates the proliferation of B cell progenitors, thymocytes, and mature T cells through an interaction with a high affinity receptor (IL-7R) belonging to the hematopoietin receptor superfamily. We have further addressed the role of IL-7 and its receptor during B and T cell development by generating mice genetically deficient in IL-7R. Mutant mice display a profound reduction in thymic and peripheral lymphoid cellularity. Analyses of lymphoid progenitor populations in IL-7R-deficient mice define precisely those developmental stages affected by the mutation and reveal a critical role for IL-7R during early lymphoid development. Significantly, these studies indicate that the phase of thymocyte expansion occurring before the onset of T cell receptor gene rearrangement is critically dependent upon, and mediated by the high affinity receptor for IL-7.

Definition and Treatment of Dyslexia

A committee of the Health Council of the Netherlands prepared a report on the definition and treatment of dyslexia at the request of the Minister of Health, Welfare, and Sport (see Note). The Health Council, as charged by the Health Act, is to inform the government on the state of science with respect to public health issues. The Council is entirely funded by the government but otherwise completely independent (an independence guaranteed by law). The committee was formed to answer questions regarding the provisions and funds needed for the treatment of persons with dyslexia, neuropsychological treatment modalities, in particular, and the role of speech and language therapists. Definitive decision making about reimbursement by the Dutch National Health Service for treatment by speech and language therapists in cases of dyslexia was on hold, pending the committee's report. Specific attention was requested for the following aspects: the definition of dyslexia (the characteristic symptoms of this category of developmental language disabilities); the consequences of the proposed definition for indication and treatment; the appropriate methods of treatment; the involvement of several possible professionals (e.g., neuropsychologist, remedial teacher, speech and language therapist), as well as the role of the neurologist during and in relation to the treatment process; and those situations in which treatment should be the responsibility of the health care system. This article summarizes the committee's considerations and conclusions on these different aspects.
Sign of life: A system for escalating post-disaster rescue missions in ready-made garment factories

Both severity and frequency of disasters in highly-dense industries such as ready-made garment factories have increased to an alarming level in recent times. Technological advancement addresses a number of aspects of post-disaster rescue missions for such events, however, facilitating the missions through providing real-time information about the survivors to the first responders is yet to be focused in the literature. Absence of such real-time information may create a gap between the survivors' requirements and the first responders' action. To bridge the gap, in this paper, we propose a novel system (named Sign of Life) exploiting wireless sensor networks for escalating the post-disaster rescue missions. Even though we mainly focus on ready-made garments factories in the paper, it can be utilized in other similar cases. Here, we propose a network architecture for the system and develop a prototype required for implementing the system. We present ns-2 simulation results pertinent to our proposed network architecture. Finally, we point out how we plan to enhance our proposed system in future.
An Adaptive Peer-to-Peer Overlay Scheme for Location-Based Services

One envisioned distinctive feature of smart cities is the interconnection among mobile users and vehicles, to support the fulfillment of location-based services. This can be obtained with centralized architectures, and with all the problems of scalability and robustness that such a solution involves. On the other hand, a more complex but more reliable, completely distributed approach can overcome this kind of problems. In this paper, we present the Adaptive Distributed Geographic Table (ADGT), a peer-to-peer overlay scheme suitable for the development of location-based services. In particular, the ADGT allows to efficiently retrieve peers or resources, to broadcast messages within any geographical region, and to be automatically notified about any type of information around any geographical location, following the publish/subscribe model. What mainly differentiates the ADGT from the other solutions in literature is the adaptivity of the overlay's topology to peers' mobility. Actually, the ADGT has the capability to adapt the neighborhood of each mobile peer depending on speed and direction. We have evaluated the ADGT by simulating different scenarios, and the results show that it acts well, ensuring high quality of messages dissemination and low cost in terms of data usage.
Coupled Gay Men, Parents, and In-Laws: Intergenerational Disapproval and the Need for a Thick Skin

This exploratory study applied grounded theory methodology to examine the impacts of parental and in-law disapproval on gay men's relationships. Data were collected from an accidental sample of forty men in twenty homosexual couples using a standardized, open-ended interview. The findings suggest that partnered gay men are almost certain to face antagonism from their parents and in-laws. However, most respondents denied adverse impacts of family of origin hostility. Participants described the deployment of a variety of boundary-setting coping mechanisms to protect their relationships from intergenerational antipathy. According to the results of this research clinicians may want to prepare gay men for the family crisis that is almost sure to result when they come out to their parents. Practitioners would also be advised to assess and, if necessary, help gay male couples strengthen the intergenerational, emotional boundaries around their relationships.
The potential benefits of dental implants on the oral health quality of life of people with Parkinson's disease.

OBJECTIVE To investigate how dental implants impact on the oral health quality of life of people with Parkinson's disease (PD). BACKGROUND PD is a progressive neurological disorder that can result in a number of oral health care challenges, including denture difficulties. Lack of evidence related to use of implants in PD prompted this study to investigate their use in this group of people. MATERIALS AND METHODS Nine people with PD were provided with either fixed or removable prostheses using Astra-Tech implants. Participants completed the socio-dental questionnaire, 'The Dental Impact on Daily Living Assessment' (DIDL) prior to implant surgery, and at 3 and 12 months after provision of the final prosthesis. DIDL comprises two components - the Oral Health Quality of Life Inventory (OH-QoL) and the Self-Reported Assessment of Oral Health and Functional Status (SROH). RESULTS Nine people (with an age range of 54-77 years) had implants placed. The implant success rate was 85 and 81% in the maxilla and mandible, respectively. The OH-QoL and SROH results (analysed using the one-way analysis of variance and pairwise multiple comparisons) demonstrated a significant improvement in the domains of eating and satisfaction with the prosthesis after 3 months, which was maintained at the twelve month review. The OH-QoL indicated a gradual improvement in oral well-being over the 12-month period. CONCLUSION The oral health quality of life of people with PD was improved by the use of dental implants, indicating this as a viable treatment option.
Role of Cholera Toxin in Vibrio cholerae Infection in Humans - A Review

Vibrio cholerae, the causative agent of Asiatic cholera, is a gram-negative motile bacterial species acquired via oral ingestion of contaminated food or water sources. Cholera has spread from the Indian subcontinent where it is endemic to involve nearly the whole world seven times during the past 185 years. V. cholerae serogroup O1, biotype El Tor, has moved from Asia to cause pandemic disease in Africa and South America during the past 35 years. A new serogroup, O139, appeared in south Asia in 1992, has become endemic there, and threatens to start the next pandemic. The facultative human pathogen V. cholerae represents a paradigm that evolved from environmental non-pathogenic strains by acquisition of virulence genes. The major virulence factors of V. cholerae, cholera toxin (CTX) encoded by the ctxAB genes residing in the genome of filamentous lysogenic bacteriophage (CTXɸ) and toxin coregulated pilus (TCP) encoded by vibrio pathogenicity island (VPI). CTX, a potent stimulator of adenylate cyclase, causes the intestine to secrete watery fluid rich in sodium, bicarbonate, and potassium, in volumes far exceeding the intestinal absorptive capacity, by ADP-ribosylation of the alpha subunit of the GTP-binding protein. Thus intestinal infection with V. cholerae results in the loss of large volumes of watery stool, leading to severe and rapidly progressing dehydration and shock. Without adequate and appropriate rehydration therapy, severe cholera kills about half of affected individuals. Today, cholera still remains a burden mainly for underdeveloped countries, which cannot afford to establish or to maintain necessary hygienic and medical facilities. During the last three decades, intensive research has been undertaken to unravel the virulence properties and to study the epidemiology of this significant human pathogen. This review provides an overview of the role of CTX in the occurrence of this disease in humans.
The complexity of PDGFR signaling: regulation of adipose progenitor maintenance and adipocyte-myofibroblast transition.

Dermal adipocytes are involved in the protection of skin infection, in hair growth and wound healing (1). Significant modulation of dermal adipose tissue (dWAT) can be observed in aged skin, and loss of dermal adipocytes is a hallmark of fibrotic lesions. Therefore, identification of molecular mechanisms governing adipose progenitor proliferation and self-renewal is critical to counteract depletion of adipocytes occurring with aging in the skin. Moreover, understanding adipose progenitor maintenance in general might also be important for other adipose depots.
Molecular Skin Surface-Based Transformation Visualization between Biological Macromolecules

Molecular skin surface (MSS), proposed by Edelsbrunner, is a C2 continuous smooth surface modeling approach of biological macromolecules. Compared to the traditional methods of molecular surface representations (e.g., the solvent exclusive surface), MSS has distinctive advantages including having no self-intersection and being decomposable and transformable. For further promoting MSS to the field of bioinformatics, transformation between different MSS representations mimicking the macromolecular dynamics is demanded. The transformation process helps biologists understand the macromolecular dynamics processes visually in the atomic level, which is important in studying the protein structures and binding sites for optimizing drug design. However, modeling the transformation between different MSSs suffers from high computational cost while the traditional approaches reconstruct every intermediate MSS from respective intermediate union of balls. In this study, we propose a novel computational framework named general MSS transformation framework (GMSSTF) between two MSSs without the assistance of union of balls. To evaluate the effectiveness of GMSSTF, we applied it on a popular public database PDB (Protein Data Bank) and compared the existing MSS algorithms with and without GMSSTF. The simulation results show that the proposed GMSSTF effectively improves the computational efficiency and is potentially useful for macromolecular dynamic simulations.
Culture Influence on the Perception of the Body Language by Arab and Malay Students

Intercultural communication is applied for communicating with each other among the different cultures and traditions. It highlighted the problems which faced by different communities and organizations, the problems which are natural to the person like when the people face to new culture or tradition even the religious issues. So intercultural communication here is seeking for an answer between the different nations that how they communicate with each other when they face some problems in their tradition and culture. This one highlights how the people encode a message and how they interpret a message to each other. So here in this paper interaction is between students of Arabs and Malays from National University of Malaysia and it deals with their body language especially hand gestures. This paper is based on the Micheal Byram theory of language. In this quantitative research some questions will distribute among the students and the similarities and differences between their sign languages will be highlighted.
Publishing and Querying Government Multidimensional Data Using QB4OLAP

The web is changing the way in which data warehouses are designed, used, and queried. With the advent of initiatives such as Open Data and Open Government, organizations want to share their multidimensional data cubes and make them available to be queried online. The RDF data cube vocabulary (QB), the W3C standard to publish statistical data in RDF, presents several limitations to fully support the multidimensional model. The QB4OLAP vocabulary extends QB to overcome these limitations, and provides the distinctive feature of being able to implement several OLAP operations, such as rollup, slice, and dice using standard SPARQL queries. In this paper we present QB4OLAP Engine, a tool that transforms multidimensional data stored in relational DWs into RDF using QB4OLAP, and apply the solution to a real-world case, based on the national survey of housing, health services, and income, carried out by the government of Uruguay.
Predicting Students ’ Retention of Facts from Feedback During Training

An effective way to teach facts to students is to test them as they study (Roediger & Karpicke, 2006). The answers students provide, as well as their response latencies, constitute feedback that an intelligent tutoring system (ITS) can use to determine how well they have learned study material. This capability enables an ITS to appropriately allocate a student’s future study time to facts whose additional study would bring greatest benefit. The goal of this paper is a first step along this path: to propose and evaluate algorithms that predict a specific student’s memory for a specific fact being learned from feedback during study. We employed several methods, ranging from standard statistical approaches like logistic regression to a model designed specifically for this task, a Bayesian generalization of the ACT-R cognitive architecture. The methods we explored all proved to be of similar predictive power. We believe we are the first to show that latencies on correct responses made during study are predictive of future test performance. However, latencies are not as useful as accuracy of responses during study and do not yield any predictive power beyond what is available in accuracies.
Imaging in the diagnosis and prognosis of traumatic brain injury.

INTRODUCTION Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Improved understanding of the impact of head injury and the extent and development of neuronal loss and cognitive dysfunction could lead to improved therapy and outcome for patients. AREAS COVERED This paper reviews the currently available imaging techniques and defines their role in the diagnosis, management and prediction of outcome following traumatic brain injury. These imaging techniques provide delineation of the structural, physiological and functional derangements that result following acute injury, and map their development and association with late functional deficits. Imaging tools also have a role in defining the pathophysiological mechanisms responsible for further neuronal loss following the primary injury. Finally, this paper provides an overview of the role of functional imaging in classifying unresponsive coma and defining functional reorganisation of the brain following injury. EXPERT OPINION Brain imaging is of key importance in TBI management, enabling efficient and accurate diagnoses to be made, informing management decisions and contributing to prognostication. Developments in imaging techniques promise to improve understanding of the structural and functional derangements, improve management and guide the development and implementation of novel neuroprotective strategies following head injury.
