Users and Nonusers: Interactions between Levels of Facebook Adoption and Social Capital

Although Facebook is the largest social network site in the U.S. and attracts an increasingly diverse userbase, some individuals have chosen not to join the site. Using survey data collected from a sample of non-academic staff at a large Midwestern university (N=614), we explore the demographic and cognitive factors that predict whether a person chooses to join Facebook. We find that older adults and those with higher perceived levels of bonding social capital are less likely to use the site. Analyzing open-ended responses from non-users, we find that they express concerns about privacy, context collapse, limited time, and channel effects in deciding to not adopt Facebook. Finally, we compare non-adopters against users who differ on three dimensions of use. We find that light users often have social capital outcomes similar to, or worse than, non-users, and that heavy users report higher perceived bridging and bonding social capital than either group.
Inadequate experimental methods and erroneous epilepsy diagnostic criteria result in confounding acquired focal epilepsy with genetic absence epilepsy

Here we provide a thorough discussion of the study conducted by Rodgers et al. (J Neurosci. 2015; 35(24):9194-204. doi: 10.1523/JNEUROSCI.0919-15.2015) to investigate focal seizures and acquired epileptogenesis induced by head injury in the rat. This manuscript serves as supplementary document for our letter to the Editor to appear in the Journal of Neuroscience. We find that the subject article suffers from poor experimental design, very selective consideration of antecedent literature, and application of inappropriate epilepsy diagnostic criteria which, together, lead to unwarranted conclusions.
An Image Compression Algorithm Based on Integer Wavelet Transform

Integer wavelet transform (IWT) and IWT-Based image-compression offer many advantages over traditional wavelet. But every subband coefficients of the IWT-Image have smaller dynamic change value and worse energy compaction than the first generation wavelet. Those reduce efficiency of embedded zerotree wavelet (EZW) coding. This paper proposes "integer square quantization threshold from 1" instead of "2 of integer power quantization threshold" during EZW coding. It shortens the distances of every quantization threshold, reduces probability of the important coefficients in the lower quantization threshold area and increases zerotrees. It reduces the coding signs and does not code the zerotrees of the most high-frequency subbands. The experiments results show that integer square zerotree wavelet (ISZW) coding algorithm solves the low efficiency of EZW based on IWT and improves the performance of compression algorithm. It may be used in still picture compression and transmission.
Prunus transcription factors: breeding perspectives

Many plant processes depend on differential gene expression, which is generally controlled by complex proteins called transcription factors (TFs). In peach, 1533 TFs have been identified, accounting for about 5.5% of the 27,852 protein-coding genes. These TFs are the reference for the rest of the Prunus species. TF studies in Prunus have been performed on the gene expression analysis of different agronomic traits, including control of the flowering process, fruit quality, and biotic and abiotic stress resistance. These studies, using quantitative RT-PCR, have mainly been performed in peach, and to a lesser extent in other species, including almond, apricot, black cherry, Fuji cherry, Japanese apricot, plum, and sour and sweet cherry. Other tools have also been used in TF studies, including cDNA-AFLP, LC-ESI-MS, RNA, and DNA blotting or mapping. More recently, new tools assayed include microarray and high-throughput DNA sequencing (DNA-Seq) and RNA sequencing (RNA-Seq). New functional genomics opportunities include genome resequencing and the well-known synteny among Prunus genomes and transcriptomes. These new functional studies should be applied in breeding programs in the development of molecular markers. With the genome sequences available, some strategies that have been used in model systems (such as SNP genotyping assays and genotyping-by-sequencing) may be applicable in the functional analysis of Prunus TFs as well. In addition, the knowledge of the gene functions and position in the peach reference genome of the TFs represents an additional advantage. These facts could greatly facilitate the isolation of genes via QTL (quantitative trait loci) map-based cloning in the different Prunus species, following the association of these TFs with the identified QTLs using the peach reference genome.
Housing Insecurity among Urban Fathers

This article examines housing insecurity among an understudied population: urban fathers of young children. Housing security is of particular importance for vulnerable populations, and urban fathers, many of whom face unemployment and monitoring from the child support and criminal justice systems, often rely on this security to mitigate the socioeconomic challenges they face. By assessing the extent and type of housing insecurity affecting urban fathers, we identify a potentially serious source of disadvantage facing families more broadly. A year after the birth of a new child, fully a quarter of fathers reported significant housing insecurities with 3% experiencing homelessness. Results suggest that from 9 to 12% of fathers are doubling up, relying on others for living expenses, and moving more than once every year. Finally, only half of fathers had been able to maintain housing security over the three to four years since the focal child? s birth.
Transforming strategic goals of CRM into process goals and activities

Purpose – The purpose of this paper is to address two questions: what is the difference between relationship processes and purely product‐oriented processes? And to answer this question we should bear in mind what we mean by relationship, and why a customer is willing to establish and maintain a relationship at all.Design/methodology/approach – An empirical analysis subjected the motives of customers and factors for the establishment and expansion of customers' relationships. In this context the relationship motives and factors can act as base to derive strategic goals of CRM and relationship processes in a further step.Findings – Based on strategic relationship goals the paper will give answers to a systematic identification and engineering of relationship activities and processes. Thereby relationship‐oriented activities complement present product‐oriented processes. In contrast to this we derive purely relationship‐oriented processes as well, such as the customer recovery process. Such processes do not.
The distribution of tau in the mammalian central nervous system

We have determined the biochemical and immunocytochemical localization of the heterogeneous microtubule-associated protein tau using a monoclonal antibody that binds to all of the tau polypeptides in both bovine and rat brain. Using immunoblot assays and competitive enzyme- linked immunosorbent assays, we have shown tau to be more abundant in bovine white matter extracts and microtubules than in extracts and microtubules from an enriched gray matter region of the brain. On a per mole basis, twice-cycled microtubules from white matter contained three times more tau than did twice-cycled microtubules from gray matter. Immunohistochemical studies that compared the localization of tau with that of MAP2 and tubulin demonstrated that tau was restricted to axons, extending the results of the biochemical studies. Tau localization was not observed in glia, which indicated that, at least in brain, tau is neuron specific. These observations indicate that tau may help define a subpopulation of microtubules that is restricted to axons. Furthermore, the monoclonal antibody described in this report should prove very useful to investigators studying axonal sprouting and growth because it is an exclusive axonal marker.
Social Class, Gender and Ethnic Differences in Subjects Taken at Age 14.

ABSTRACT In this paper, we identify patterns of subject and qualification choices made at age 14. Much of the previous research on ‘subject choice’ has focussed on the later stages of educational trajectories, particularly Higher Education. However, the choices made at early branching points can limit pupils’ subsequent options, potentially contributing to educational inequalities. This paper identifies the patterns of General Certificate of Secondary Education (GCSE) subjects chosen by a cohort of young people born in 1989/1990. We make use of the Next Steps data (formerly the Longitudinal Study of Young People in England (LSYPE)) which is linked to the National Pupil Database. We develop an approach to measuring the academic selectivity of subjects and qualifications. We examine the roles of social class, parental education, income, gender and ethnicity in determining participation in these curriculum groupings. Using measures of prior attainment from age thirteen, we address the question of whether curriculum differentials simply reflect differences in prior attainment or whether they actually operate above and beyond existing inequalities. We find clear socio-economic, gender, ethnic and school-level differences in subjects studied which cannot be accounted for by prior attainment.
Metrics for best practice networks analysis

Best practice networks are thematic social networks focused on sharing common area works and goals. The analysis of user behavior on social network is fundamental to tune services and stimulate the network growth. This is even more relevant for best practice collaborative networks where details about collaboration may lead to understand the effective activities and role of people in the several groups. In this paper, a set of metrics for analyzing user behavior related to downloads and other aspects on the best practice network is presented. The metrics and the work presented have been applied, and are currently active, as administrative tools for the Mobile Medicine best practice network.
User driven systems to bridge the semantic gap

In this tutorial relevant development in user-driven image annotation and retrieval is reviewed. This includes descriptive learning models starting from empirical parameter adaptation to approaches considering optimisations and complex parametric as well as non-parametric distributions. The review also includes discriminative learning models focusing on estimating the boundaries between classes rather then exact class distribution. A new approach to infer semantic concepts in images is also described. This approach draws on several important ideas including multi-feature space, learning technique pertaining to user provided relevance and an object based modelling to link semantic terms and visual objects.

C 2 Domain Ontology within Our Lifetime Paper ID 120 C 2 Concepts , Theory , and Policy

Agile Command and Control (C2) requires agile information sharing with an increasingly wide variety of military and non-military partners. While current " net-centric " approaches may improve information sharing within a particular niche of C2, they do not support information sharing across the larger C2 domain. Although not a silver bullet, the development and application of a C2 domain ontology to improve C2 data and service integration appears to be increasingly realistic. In fact, there are several examples of successful ontology applications in domains such as medicine, biology, and engineering, and the new discipline of Applied Ontology is emerging. C2 data, architecture, and conceptual modeling activities which bear a close resemblance to applied ontology activities are also beginning to take shape, and there are several efforts with near to mid-term promise as elements of a C2 domain ontology. This paper provides an overview of ontology, examples of existing ontologies, key C2 data, architecture, and modeling efforts with applicability to a C2 domain ontology, and recommendations regarding the way ahead. It is the authors' conclusion that development of a practical C2 domain ontology is necessary and feasible in the near to mid term, and that efforts should commence following the principles and best practices of the applied ontology community.
A novel image evaluation method for three-dimensional laser scanning in Full Degrees of Freedom

In three-dimensional laser light scanning in Full Degrees of Freedom, the laser stripe profile information of some images is damaged and can't be detected normally as result of the scanning unit dithering and variations of ambient light. Aiming at this problem, a novel laser image evaluation method is presented. The mathematical model is built to evaluate contrast, luminance and ambiguity respectively. According to weight factor of each evaluation sub-item, the total evaluation score is obtained, and is the basis for whether to process the image or not. Experiment show that this method is consistent with the result of laser stripe profile detection.
The Heart and Pulmonary Circulation at High Altitudes: Healthy Highlanders and Chronic Mountain Sickness

More than 140 million people worldwide live >2500 m above sea level. Of them, 80 million live in Asia, and 35 million live in the Andean mountains. This latter region has its major population density living above 3500 m. The primary objective of the present study is to review the physiology, pathology, pathogenesis, and clinical features of the heart and pulmonary circulation in healthy highlanders and patients with chronic mountain sickness. A systematic review of worldwide literature was undertaken, beginning with the pioneering work done in the Andes several decades ago. Original articles were analyzed in most cases and English abstracts or translations of articles written in Chinese were reviewed. Pulmonary hypertension in healthy highlanders is related to a delayed postnatal remodeling of the distal pulmonary arterial branches. The magnitude of pulmonary hypertension increases with the altitude level and the degree of exercise. There is reversal of pulmonary hypertension after prolonged residence at sea level. Chronic mountain sickness develops when the capacity for altitude adaptation is lost. These patients have moderate to severe pulmonary hypertension with accentuated hypoxemia and exaggerated polycythemia. The clinical picture of chronic mountain sickness differs from subacute mountain sickness and resembles other chronic altitude diseases described in China and Kyrgyzstan. The heart and pulmonary circulation in healthy highlanders have distinct features in comparison with residents at sea level. Chronic mountain sickness is a public health problem in the Andean mountains and other mountainous regions around the world. Therefore, dissemination of preventive and therapeutic measures is essential.
CROSS-CORRELATION NEURAL NETWORK : A NEW NEURAL NETWORK CLASSIFIER

A neural network is an excellent classifier; however, its performance depends directly on the size and quality of training samples presented to the network. This paper proposes a new neural network approach to deal with the classification problem by applying the concept of cross-correlation to measure the likeness or similarity between the incoming input pattern and the reference patterns of each class. This proposed model has been benchmarked against the fuzzy ARTMAP neural network and many other different structures studied in the previous researches. The experimental results on four benchmark problems show that the proposed network has the best performance among all. Key-Words: Neural Network, Cross-correlation, Classification, Data Mining
Indexing Query Graphs to Speedup Graph Query Processing

Subgraph/supergraph queries although central to graph an- alytics, are costly as they entail the NP-Complete problem of subgraph isomorphism. We present a fresh solution, the novel principle of which is to acquire and utilize knowledge from the results of previously executed queries. Our ap- proach, iGQ, encompasses two component subindexes to identify if a new query is a subgraph/supergraph of pre- viously executed queries and stores related key informa- tion. iGQ comes with novel query processing and index space management algorithms, including graph replacement policies. The end result is a system that leads to signifi- cant reduction in the number of required subgraph isomor- phism tests and speedups in query processing time. iGQ can be incorporated into any sub/supergraph query processing method and help improve performance. In fact, it is the only contribution that can speedup significantly both subgraph and supergraph query processing. We establish the princi- ples of iGQ and formally prove its correctness. We have im- plemented iGQ and have incorporated it within three popu- lar recent state of the art index-based graph query process- ing solutions. We evaluated its performance using real-world and synthetic graph datasets with different characteristics, and a number of query workloads, showcasing its benefits.
Inhibition of Converting Enzyme of the Renin‐Angiotensin System in Kidneys and Hindlegs of Dogs

The activity of angiotensin-converting enzyme in hindlegs and kidneys was compared in anesthetized dogs. Intra-arterial injections of angiotensin I or angiotensin II to one kidney or one hindleg caused dose-dependent decreases in blood flow in that vascular bed. An inhibitor of angiotensin-converting enzyme activity did not affect the vasoconstrictor activity of angiotensin II but substantially reduced that of angiotensin I. The reduction in vasoconstrictor activity of angiotensin I during enzyme inhibition was used to calculate conversion of angiotensin I to angiotensin II. There was 40% conversion in hindleg but only 2.1% in kidney. After intra-arterial injection of angiotensin I, bioassay of angiotensin II in the renal or iliac venous blood indicated that 60−90% of freshly formed angiotensin II was inactivated before leaving the kidney or hindleg. The results show that converting enzyme activity is much greater in hindlegs than in kidneys and that the endogenously formed angiotensin II following intra-arterial injection of angiotensin I is destroyed to the same extent as intra-arterially injected angiotensin II. Intra-arterial infusion of the enzyme inhibitor increased hindleg blood flow in half of the dogs; renal blood flow increased in only one dog. The inhibitor did not affect vascular responses produced by norepinephrine, histamine, vasopressin, or prostaglandin F2α but the effects of bradykinin were potentiated.
The polymerization of actin: II. how nonfilamentous actin becomes nonrandomly distributed in sperm: evidence for the association of this actin with membranes

At an early stage in spermiogenesis the acrosomal vacuole and other organelles including ribosomes are located at the basal end of the cell. From here actin must be transported to its future location at the anterior end of the cell. At no stage in the accumulation of actin in the periacrosomal region is the actin sequestered in a membrane-bounded compartment such as a vacuole or vesicle. Since filaments are not present in the periacrosomal region during the accumulation of the actin even though the fixation of these cells is sufficiently good to distinguish actin filaments in thin section, the actin must accumulate in the nonfilamentous state. The membranes in the periacrosomal region, specifically a portion of the nuclear envelope and the basal half of the acrosomal vacuole membrane, become specialized morphologically in advance of the accumulation of actin in this region. My working hypothesis is that the actin in combination with other substances binds to these specialized membranes and to itself and thus can accumulate in the periacrosmoal region by being trapped on these specialized membranes. Diffusion would then be sufficient to move these substances to this region. In support of this hypothesis are experiments in which I treated mature sperm with detergents, glycols, and hypotonic media, which solubilize or lift away the plasma membrane. The actin and its associated proteins remain attached to these specialized membranes. Thus actin can be nonrandomly distributed in cells in a nonfilamentous state presumably by its association with specialized membranes.
A parallel and distributed routing algorithm with a hierarchical connection management architecture for ATM/B-ISDN

In this paper, we propose a parallel and distributed routing algorithm for the ATM/B-ISDN transport networks. In the proposed routing algorithm, a hierarchical connection management architecture is used where each subnetwork has its own connection management functions to find the shortest path for the requested subnetwork connections and the routing information is merged by the upper-level domain subnetwork to find the shortest path in the merged domain of upper-level. This subnetwork routing is performed in each subnetwork in hierarchy, providing maximized parallel and distributed processing capability. The proposed parallel and distributed routing algorithm can reduce the routing and connection setup time in a large-scale network, such as a public B-ISDN.
Distributed Graphics Pipelines on the Grid

jgViz uses standard grid technologies and Chromium cluster graphics software to schedule the best available distributed graphics pipeline. Visualization of large data sets using computer graphics techniques has become a mainstream requirement for many scientists and engineers. However, achieving interactive performance when rendering a complex visualization often requires high-performance computing facilities. One solution is to exploit real-time graphics accelerators, which are used in the full range of computing devices from games consoles and set-top boxes to supercomputers and advanced training simulators. At the same time, the service infrastructure for distributed networks has produced the third generation of the connected world: the grid. jgViz, our Java-implemented grid visualization system, uses grid functionality to enable transparent access to reliable parallel graphics pipelines. Lightweight and highly portable, jgViz aims to be plug-and-play for the existing grid resource allocation mechanism
