Social Network Signatures: A Framework for Re-identification in Networked Data and Experimental Results

Data on large dynamic social networks, such as telecommunications networks and the Internet, are pervasive. However, few methods conducive to efficient large-scale analysis exist. In this paper, we focus on the task of re-identification. Re-identification in the context of dynamic networks is a matching problem that involves comparing the behavior of networked entities across two time periods. Prior research has reported success in the domains of e-mail alias detection, author attribution, and identifying fraudulent consumers in the telecommunications industry. In this work, we address the question of "why are we able to re-identify entities on real world dynamic networks? " Our contribution is two-fold. First, we address the challenge of scale with a framework for matching that does not require pairwise comparisons to ascertain the similarity scores between networked entities. Second, we show our method is robust against missing links but less tolerant to noise. Using our framework, we provide a performance estimate for re-identification on networks based solely on their degree distribution and dynamics. This work has significant implications for re-identification problems where scale is a challenge as well as for problems where false negatives (e.g.,when fraudulent consumers are not labeled as fraudulent) cannot be observed.
Contributions of Proprioception to Navigation in Virtual Environments

Users immersed in virtual environments (VEs) are prone to disorientation and have difficulty transferring spatial knowledge to the real world. A single experiment investigated the contribution of inadequate proprioception to this problem by providing participants with interfaces to a virtual environment that either did (a walking interface) or did not (a joystick) afford proprioceptive feedback similar to that obtained during real walking. The 2 groups explored a large, complex building using a low-resolution head-mounted display. Later, their navigational abilities within the actual building were compared with those of control groups who either studied a map of the building, walked through the real building, or received no prior training. The walking interface conveyed no benefit on an orientation task performed during training in the VE, but it did benefit participants when they tried to find objects in the real world. Actual or potential applications include simulations of environments that are normally explored on foot but cannot be readily visited, such as infantry battlefields and facilities contaminated with chemical, biological, or radiological materials.

Probiotic viability – does it matter?

Probiotics are viable by definition, and viability of probiotics is often considered to be a prerequisite for the health benefits. Indeed, the overwhelming majority of clinical studies in the field have been performed with viable probiotics. However, it has also been speculated that some of the mechanisms behind the probiotic health effects may not be dependent on the viability of the cells and, therefore, is also possible that also non-viable probiotics could have some health benefits. The efficacy of non-viable probiotics has been assessed in a limited number of studies, with varying success. While it is clear that viable probiotics are more effective than non-viable probiotics and that, in many cases, viability is indeed a prerequisite for the health benefit, there are also some cases where it appears that non-viable probiotics could also have beneficial effects on human health.
Opinions of Psychiatric Hospital Personnel and College Students toward Alcoholism, Mental Illness, and Physical Disability: An Exploratory Study

This exploratory study investigated the attitudes of 303 college students and 521 psychiatric hospital staff members toward alcoholism, mental illness, and physical disability. The Attitude Toward Disabled Persons Scale was adapted to yield two additional scales probing alcoholism and mental illness. Statistically significant differences were not found between the mean scores of the college students and the hospital personnel on the scales. Both groups were significantly more accepting of physical disability than of the other two illnesses. The students were slightly, and the hospital personnel were significantly, more accepting of alcoholics than of mentally ill people but the mean scores of both groups on both scales were still within the non-accepting range.
Heterosynaptic long‐term potentiation at interneuron–principal neuron synapses in the amygdala requires nitric oxide signalling

Non‐technical summary Long‐lasting changes in efficacy of cell–cell communication (long‐term potentiation; LTP) at specialized sites (synapses) between neurons in the brain are thought to underlie forms of learning and memory. These forms of LTP can occur at excitatory synapses and inhibitory synapses, thus in‐ or decreasing the activity of neurons. We provide evidence for a novel form of LTP at inhibitory synapses (LTPi) on a subset of neurons in the amygdala of mice, a brain region involved in fear and anxiety. This LTPi enhances the release of the inhibitory neurotransmitter GABA at synapses between inhibitory interneurons and excitatory principal neurons (PNs) in a sub‐region of the amygdala. The described LTPi is heavily dependent on the production and diffusion of the volatile gas nitric oxide (NO), produced by PNs during stages of increased activity. These findings indicate that NO‐mediated long‐term regulation of inhibitory transmission in the amygdala might contribute to the learning of fear.
Elaboración de versiones reducidas de instrumentos de medida: una perspectiva práctica

Resumen El objetivo del presente trabajo consiste en mostrar, desde una perspectiva practica, las pautas que pueden seguirse para elaborar una version reducida de un instrumento de medida. Para ello, se describe exhaustivamente el proceso de elaboracion de la version reducida en lengua vasca de la escala CDS ( Children's Depression Scale ; Lang y Tisher, 1978) que mide la depresion en ninos/as y adolescentes. En un primer estudio, se seleccionan los items que configuran la version reducida del CDS (CDS-R) a partir de los analisis realizados en una muestra de 886 ninos/as y adolescentes a los que se les administro la version extensa del CDS adaptada a la lengua vasca (Balluerka, Gorostiaga y Haranburu, 2012). Posteriormente, se procede a la validacion del CDS-R en una muestra de 2.165 participantes. En este segundo estudio se examinan la estructura factorial, la consistencia interna y la estabilidad temporal del instrumento, asi como la relacion que presentan sus dimensiones con el sexo, el rendimiento academico, la inteligencia emocional y el apego. De esta forma, se obtienen evidencias sobre la fiabilidad y la validez de la version reducida del instrumento, lo que garantiza una adecuada evaluacion del constructo que este pretende medir.
Innovation, cultural values, and the management of change in British hospitals

Abstract This paper describes the results of a study of innovation in the management teams of 27 UK hospitals. It is argued that the content of innovations provides an accurate representation of the underlying cultural values of the management teams, and the cultural values which they seek to purvey within the wider organizational settings. The authors propose that values in action (as opposed to espoused values) are manifest in the range of innovations introduced by top management within organizations. Using a typology of organizational culture, they categorize the innovations introduced by the management teams, in order to map their underlying cultural values. The results indicate predominant orientations of hospital management teams towards rational goal and hierarchical values in the current context of health care in Britain. Internal climate and service innovations were relatively infrequent, suggesting that the hospitals were dominated by management concern for control rather than flexibility. The c.
Sacred Land or National Sacrifice Zone: The Role of Values in the Yucca Mountain Participation Process

Local participation in environmental decision making is a fundamental tenet of environmental justice. This essay examines the participation process for nuclear waste siting decisions and suggests that the lack of a viable means for discussion of competing values is a flaw in the currently used model of participation. Through analysis of the Yucca Mountain high-level nuclear waste site in the USA, I show how the lack of discussion of values occludes participation by marginalized American Indians. In particular, I examine the incommensurability between American Indian nations that value Yucca Mountain as sacred land and the federal government that values Yucca Mountain as a national sacrifice zone. I argue that Yucca Mountain acts as a polysemous value term in the controversy. My findings suggest that an environmentally just model of participation in environmental decision making must include a way to account for incommensurable values and cultural differences. Further, I highlight the lessons we can learn from the Yucca Mountain project as we deliberate about what to do with nuclear waste.
Identifying the suitable reduction technique for mining medical data

In real world, organizations often have large amount of data that are stored in databases. The large size of data makes data analysis difficult as data are more complex in terms of number of attributes and number of objects. The use of a sufficient number of attributes and objects are one way to overcome the problem. There are many techniques that can be used to minimize the number of attributes in data mining. In this paper, three reduction techniques namely Genetic Algorithm (GA), Principal Component Analysis (PCA), and Johnson have been tested on medical domain using 5 datasets which obtained from UCI machine learning archive. The study examines which reduction technique is most suitable for medical datasets. In addition, the study also identifies the ranking of the three techniques based on percentage accuracy and number of selected attributes.
How what we tell becomes what we know: Listener effects on speakers’ long‐term memory for events

Telling others about past events can be viewed as rehearsing one's memory for a set of events, and a recollection on one occasion might exert long‐term influences on event memory. Because variations in the social context of recollection affect how we tell others about events, such variations can also come to influence long‐term memory. In our study, we varied aspects of the listener's behavior during an event recollection by having participants view brief movie excerpts, and then we had them either recount those excerpts to attentive listeners, recount them to distracted listeners, or not recount them at all. We then compared participants’ long‐term memory for the movie excerpts. Our results show that attentive listeners facilitate long‐term memory, whereas situations with distracted listeners are difficult to distinguish from the situations with no listener and with no recounting at all. The paradigm and these exploratory results represent one potential avenue for investigating social aspects of memory.
Ca 2+ -assisted receptor-driven endocannabinoid release: mechanism relevant to associate pre- and postsynaptic activities

Endogenous cannabinoids (endocannabonoids) serve as retrograde messengers at synapses in various regions of the brain. They are released from postsynaptic neurons and cause transient and long-lasting reduction of neurotransmitter release through activation of presynaptic cannabonoid receptors. Endocannabinoid release is induced by either postsynaptic Ca 2+ elevation or activation of G q/11 -coupled receptors. When these two stimuli coincide, endocanabinoid release is markedly enhanced, which is attributed to the Ca 2+ dependency of phospholipase C β (PLC β ). This Ca 2+ -assisted receptor-driven endocannabinoid release is suggested to participate in various forms of synaptic plasticity, including short-term associative plasticity in the cerebellum and spike-timing dependent long-term depression in the somatosensory cortex. In these forms of plasticity, PLC β appears to function as a coincident detector of pre- and postsynaptic activities.
Privatisation Around the World: New Evidence from Panel Data

This paper presents new evidence about privatisation processes and their determinants from a panel of 34 countries over the 1977-99 period. The empirical analysis shows that privatisation takes place typically in wealthy and democratic countries, endowed with deep and liquid stock markets, and is affected by the governing political majority and public sector budget constraints. But the extent of privatisation in terms of revenues and stakes sold appears more limited in civil law countries, where shareholders are poorly protected, banks powerful, and capital markets less developed.
Wireless-powered cellular networks: key challenges and solution techniques

Energy harvesting from ambient sources is emerging as a sustainable and environmentfriendly technique to prolong the lifetime of wireless devices. However, harvesting energy from these sources may not be feasible for quality- of-service (QoS)-constrained wireless applications. As such, dedicated wireless-powered cellular networks (WPCNs) are currently being investigated to ensure the reliability as well as improved battery lifetime of the wireless devices. With emerging WPCNs, a true wireless network can be envisioned, which is free of connectors, cables, and battery access panels, and guarantees freedom of mobility. To illustrate and understand the design requirements of WPCNs, this article first points out the key challenges of designing energy-harvesting cellular networks. These include the doubly near-far problem, the signal-to-noise ratio (SNR) outage experienced by the energy-harvesting devices located toward the cell-edge, the spatial characterization of the SNR outage zone, the additional resource consumption at energy transmitting sources, and the problems related to designing fairness-constrained user scheduling schemes. A brief overview of the related research advancements in WPCNs and a summary of their limitations are then provided. Finally, we list a few suggestions and design considerations that can potentially tackle the major challenges in emerging WPCNs and open up new research directions.
The neural substrates of deliberative decision making: contrasting effects of hippocampus lesions on performance and vicarious trial-and-error behavior in a spatial memory task and a visual discrimination task

Vicarious trial-and-errors (VTEs) are back-and-forth movements of the head exhibited by rodents and other animals when faced with a decision. These behaviors have recently been associated with prospective sweeps of hippocampal place cell firing, and thus may reflect a rodent model of deliberative decision-making. The aim of the current study was to test whether the hippocampus is essential for VTEs in a spatial memory task and in a simple visual discrimination (VD) task. We found that lesions of the hippocampus with ibotenic acid produced a significant impairment in the accuracy of choices in a serial spatial reversal (SR) task. In terms of VTEs, whereas sham-lesioned animals engaged in more VTE behavior prior to identifying the location of the reward as opposed to repeated trials after it had been located, the lesioned animals failed to show this difference. In contrast, damage to the hippocampus had no effect on acquisition of a VD or on the VTEs seen in this task. For both lesion and sham-lesion animals, adding an additional choice to the VD increased the number of VTEs and decreased the accuracy of choices. Together, these results suggest that the hippocampus may be specifically involved in VTE behavior during spatial decision making.
A Corporation in Feminist Clothing? Young Women Discuss the Dove ‘Real Beauty’ Campaign

The Dove campaign for ‘real beauty’ has been exceptionally successful, generating public attention and increased sales. This article uses focus group analysis to investigate how young, feminist-identified women understand the campaign, and how they respond when a corporation encourages them to exercise their politics through consumption. We ask whether the campaign is seen as compatible with their vision of feminism, and whether corporations are potential vehicles for feminist change. To conceptualize critical consciousness, we suggest that classical critical theory, particularly Herbert Marcuse, can be fruitfully connected with contemporary critical and feminist theories of capitalist cooptation. Participants varied in their critiques, but relished the opportunity for deliberation, and displayed a clear capacity to disentangle ‘opposites’ like feminism and corporate profiteering. Most women saw the campaign as ‘better than nothing’ and supported some notion of ethical consumption – a kind of pragmatism that suggests the difficulty of imagining alternatives to consumer capitalism.
Data Visualisation Trends in Mobile Augmented Reality Applications

According to Google Trends, mobile augmented reality (AR) apps will, after a brief hype-associated peak and decline, show again a more steady growth in the near future. Indeed, a review of currently available mobile AR apps suggests that they are embracing practical uses instead of simply showing off the capabilities of AR. Many of these apps are making information more ubiquitous without making the user necessarily aware of the data's origins, using graphics to represent multiple datasets. There has been however little research focusing on the trends in AR and the types of data visualisations used in mobile AR. The purpose of this paper is to fill that void by presenting an analysis of currently popular mobile AR apps on the market. Our findings from this small-scale investigation give an indication of the types of visualisation styles used in current mobile AR apps and highlight suggestions for how to make the information presented more relevant, for example by using better filtering methods.
A survey on injury incidence in school children in Shantou City, China.

OBJECTIVES To study incidence characteristics and causes of injury, and its medical consequences in school children of China. METHODS A total of 2,553 school children aged 7-16 years were recruited from Shantou City in Gunagdong by cluster sampling method, and were investigated with questionnaires on cases of injuries occurred among them from October 1, 1996 to September 30, 1997. RESULTS Injuries tended to increase with children's age, with an overall incidence rate of 37.96%, higher in boys than in girls (P<0.05); and 38.1% of children had more than two episodes of injury during this period. Falls took leading place of injury incidence both in boys and girls and in all age groups. Most injuries occurred when they were playing, sporting, riding and walking at home or in school. Self-inflicted injury ranked the first place of all injuries, followed by hurt caused by others (classmates, sibling or others). Moderate and serious injuries accounted for 8% of the total with a disability rate of 121.4/100,000. CONCLUSIONS Currently, injury has become one of the serious public health problems in China. For the improvement of children survival, it is crucial to reduce their injury to strengthen research on child safety and to implement safety-promotion programs.
Arthroscopic Repair of Articular Surface Partial-Thickness Rotator Cuff Tears: Transtendon Technique versus Repair after Completion of the Tear—A Meta-Analysis

Articular surface partial-thickness rotator cuff tears (PTRCTs) are commonly repaired using two different surgical techniques: transtendon repair or repair after completion of the tear. Although a number of studies have demonstrated excellent clinical outcomes, it is unclear which technique may provide superior clinical outcomes and tendon healing. The purpose was to evaluate and compare the clinical outcomes following arthroscopic repair of articular surface PTRCT using a transtendon technique or completion of the tear. A systematic review of the literature was performed following PRISMA guidelines and checklist. The objective outcome measures evaluated in this study were the Constant Score, American Shoulder and Elbow Surgeons score, Visual Analogue Scale, physical examination, and complications. Three studies met our criteria. All were prospective randomized comparative studies with level II evidence and published from 2012 to 2013. A total of 182 shoulders (mean age 53.7 years; mean follow-up 40.5 months) were analyzed as part of this study. Both procedures provided excellent clinical outcomes with no significant difference in Constant Score and other measures between the procedures. Both procedures demonstrated improved clinical outcomes. However, there were no significant differences between each technique. Further studies are required to determine the long-term outcome of each technique.
Extending the Prevalent Consumer Loyalty Modelling: The Role of Habit Strength

Purpose: This study addresses the role of habit strength in explaining loyalty behaviour.Design/methodology/approach: The study uses 2063 consumers’ data from a survey in Denmark and Spain, and multigroup structural equation modelling to analyse the data. The paper describes an approach employing the psychological meanings of the habit construct, such as automaticity, lack of awareness or very little conscious deliberation.Findings: The findings suggest that when habits start to develop and gain strength, less planning is involved, and that the loyalty behaviour sequence mainly occurs guided by automaticity and inertia. A new model with habit strength as a mediator between satisfaction and loyalty behaviour provides a substantial increase in explained variance in loyalty behaviour over the traditional model with intention as a mediator.Originality/value: This study contributes to the existent literature by providing an extension of the prevalent consumer loyalty theorizing by integrating the concept of habit strength and by generating new knowledge concerning the conscious/strategic and unconscious/automatic nature of consumer loyalty. The study derives managerial implications on how to facilitate habit formation and how to influence habit-based versus intention-based loyalty behaviour. The external validity of this study is assured by nationwide representative samples in two countries.
Validation of the DSSI-10 to Measure Social Support in a General Population

Objective: The purpose of this study was to validate the 10-item DSSI as a brief measure of social support for use in diverse adult populations. Methods: EFA was performed on 2010 Arizona Health Survey (AHS) data (n = 8215). Confirmatory Factor Analysis (CFA) then confirmed the factors structure by gender, ethnicity, and age, as well as for the total population. DSSI-10 and subscales were compared with variables related to social support. Results: CFI confirms this structure exhibits a good model fit. Low self-reported health status and low self-reported quality of life were related to lower DSSI scores. Living alone was significantly negatively related to the DSSI-10. Conclusions: Researchers may confidently use DSSI-10 to measure social support for diverse adult populations. This instrument can be used in epidemiological studies to increase understanding of mental and physical health in relationship to social supports in the general population.
