Relationships of perceptions of organizational climate to organizational structure, context, and hierarchical position.

The authors would like to thank John Fairhead for his help with the fieldwork, Mrs. P. Clark and Mrs. R. Goodkin for their help in data handling, and Diana Pheysey for her many contributions to all aspects of the study. This paper considers the concept of organizational climate and examines the relationships to be expected between different aspects of climate and various dimensions of organizational structure and context. The suggested relationships are examined using data from 387 respondents working at all levels in 14 different work organizations. Examination of the effect of hierarchical level on perceptions of organizational climate showed significant variations by level.1
When Optimal Is Just Not Good Enough: Learning Fast Informative Action Cost Partitionings

Several recent heuristics for domain independent planning adopt some action cost partitioning scheme to derive admissible heuristic estimates. Given a state, two methods for obtaining an action cost partitioning have been proposed: optimal cost partitioning, which results in the best possible heuristic estimate for that state, but requires a substantial computational effort, and ad-hoc (uniform) cost partitioning, which is much faster, but is usually less informative. These two methods represent almost opposite points in the tradeoff between heuristic accuracy and heuristic computation time. One compromise that has been proposed between these two is using an optimal cost partitioning for the initial state to evaluate all states. In this paper, we propose a novel method for deriving a fast, informative cost-partitioning scheme, that is based on computing optimal action cost partitionings for a small set of states, and using these to derive heuristic estimates for all states. Our method provides greater control over the accuracy/computation-time tradeoff, which, as our empirical evaluation shows, can result in better performance.
RDDShare: Reusing Results of Spark RDD

In recent years, Spark has become a hotspot for big data processing. For a single user, Spark provides the cache method to share the results between the jobs in a single application. When accessed concurrently by multi users, there may exist same computation among the submitted applications, however, Spark does not provide a method to share computing results between applications. In traditional databases, one way to optimize the performance of queries is to cache part or all of the results of a query to share with other requests. Based on this, we propose RDDShare system based on Spark SQL to manage the cache and reuse the results. Finally, the results of simulate experiments show that RDDShare system can significant optimize the query performance of Spark SQL.

Robotic Fish Localization and Tracking Using Simultaneous Perturbation-Neural Algorithm

Fish and aquatic amphibians use the lateral line system, consisting of arrays of hair-like neuromasts, as an important sensory organ for prey/predator detection, communication, and navigation. In this paper a novel bio-inspired artificial lateral line system is proposed for underwater robots and vehicles by exploiting the inherent sensing capability of ionic polymer-metal composites (IPMCs). Analogous to its biological counterpart, the IPMC-based lateral line processes the sensor signals through a neural network. The effectiveness of the proposed lateral line was validated in localization of underwater motion source such as a flapping foil tail. In particular, as a proof of concept, a prototype with Body Length (BL) of 8 cm, comprising five millimeter-scale IPMC sensors, was constructed and tested. Experimental results showed that the IPMC-based lateral line could localize the sources from 4-5 BLs away, with a localization error comparable to source placement resolution at the source-sensor separation of 1 BL. In addition to the ease of fabrication, these results established the advantages of the proposed approach over other reported artificial lateral lines, in terms of both localization range and accuracy.
CMMI distilled

The author targets the book also to technnology managers charged with implementing enterprise solutions that incorporate wireless technology. Although they could benefit from seeing global view and a wider context of their work, I should warn a reader about rather introductory view of the book's topic. It will not suffice for technical managers and people whose job is to implement wireless technology within an organization. For experienced people who already work in this area, most of the book would be too elementary.
All-Transfer Learning for Deep Neural Networks and Its Application to Sepsis Classification

In this article, we propose a transfer learning method for deep neural networks (DNNs). Deep learning has been widely used in many applications. However, applying deep learning is problematic when a large amount of training data are not available. One of the conventional methods for solving this problem is transfer learning for DNNs. In the field of image recognition, state-of-the-art transfer learning methods for DNNs re-use parameters trained on source domain data except for the output layer. However, this method may result in poor classification performance when the amount of target domain data is significantly small. To address this problem, we propose a method called All-Transfer Deep Learning, which enables the transfer of all parameters of a DNN. With this method, we can compute the relationship between the source and target labels by the source domain knowledge. We applied our method to actual two-dimensional electrophoresis image~(2-DE image) classification for determining if an individual suffers from sepsis; the first attempt to apply a classification approach to 2-DE images for proteomics, which has attracted considerable attention as an extension beyond genomics. The results suggest that our proposed method outperforms conventional transfer learning methods for DNNs.
A Fast Algorithm for Sparse Channel Estimation via Orthogonal Matching Pursuit

Channels with a sparse impulse response arise in a variety of wireless communication applications, such as high definition television (HDTV) terrestrial transmission and underwater acoustic communications. By exploiting the sparsity of the channel, this paper proposes a fast algorithm for sparse channel estimation based on a greedy algorithm called orthogonal matching pursuit (OMP). The proposed fast OMP-based channel estimation algorithm has a low computational complexity of $O(KN\log N)$ with $K$ and $N$ the channel sparsity level and signal length, respectively. The fast OMP is competitive to the $\ell_1$-minimization based methods in terms of estimation accuracy. In addition, the fast OMP is faster and easier to implement. Therefore it is an attractive alternative to the $\ell_1$-minimization approaches. Simulation results are provided to demonstrate the performance of the fast OMP algorithm.
The Perception of Family Conflict by Parents Living with HIV/AIDS and Their Adolescent Children

Abstract This study explores discrepancies in perceiving family conflict between HIV-infected parents and their adolescent children aged 12 to 22. A representative sample of 382 adolescent children and their HIV+ parents were recruited and assessed over 4 years. Relationships between discrepancies in perception and family demographics and the impact of discrepancies on adolescent adjustment are examined. A significant gap in perceiving family conflict was reported between parents and young adolescents aged 12. A higher level of discrepancy was associated with poor economic status, lower parental education, parental hard drug use, and negative parental coping style. Behavioral intervention programs for adolescents must consider both parents' and adolescents' psychosocial status and behavioral indicators as well as their impact on perceptions of family conflict.
Home-Based Sexuality Education

This article explores how and why parents in rural Nigeria discuss sexuality-related matters with their adolescent children. The data presented here demonstrate that parents relegate sexuality to the domain of the dangerous, unpleasant, and unsavory while speaking to their children about it. Family sexuality communications offer parents a veritable cultural space to manage and control young people's sexuality. It is asserted that many Nigerian parents who discuss sexuality issues with their adolescent children compound the difficulties the young people encounter in accessing accurate and adequate sexuality information and in developing the associated power and mastery over their own sexual identity. Interventions that will enable parents to both give and allow their children early access to quality information on matters of sexuality are urgently needed.

A recommender system based on local random walks and spectral methods

In this paper, we design recommender systems for weblogs based on the link structure among them. We propose algorithms based on refined random walks and spectral methods. First, we observe the use of the personalized page rank vector to capture the relevance among nodes in a social network. We apply the local partitioning algorithms based on refined random walks to approximate the personalized page rank vector, and extend these ideas from undirected graphs to directed graphs. Moreover, inspired by ideas from spectral clustering, we design a similarity metric among nodes of a social network using the eigenvalues and eigenvectors of a normalized adjacency matrix of the social network graph. In order to evaluate these algorithms, we crawled a set of weblogs and construct a weblog graph. We expect that these algorithms based on the link structure perform very well for weblogs, since the average degree of nodes in the weblog graph is large. Finally, we compare the performance of our algorithms on this data set. In particular, the acceptable performance of our algorithms on this data set justifies the use of a link-based recommender system for social networks with large average degree.
Pragmatics of language in the broad autism phenotype

Abstract Researchers have reported a higher prevalence for parents of children with autism spectrum disorders (ASD) to have subtle characteristics of ASD, known as the broad autism phenotype (BAP). Deficits in the pragmatics of language are a hallmark feature of ASD and thus become a natural candidate for assessment in the BAP. This study focused on pragmatic impairments in the parents of children with ASD from India, a group that is ethnically and socio-culturally different from that of the west. Pragmatics was assessed using the broad autism phenotype questionnaire along with directly observing, recording, and profiling social communication, which is referred as ‘Observations of Social Communication’, in parents of children with ASD (PASD), down syndrome, and parents of typically developing children. The PASD group was found to be significantly different from that of the other two groups demonstrating subtle pragmatic language deficits in the BAP thus supporting similar trends in BAP across cultures.
Meeting the needs of pupils with learning difficulties. What do primary and secondary schools expect of their educational psychologists

Summary A questionnaire survey was conducted in all primary schools in the Dunbarton division of Strathclyde region (N=117) to obtain the views of headteachers regarding the involvement of local authority educational psychologists in the area of learning difficulties. This was a follow‐up to a previously published study of the views of learning support coordinators in secondary schools throughout the division. The results of the primary survey are presented and comparisons made with the secondary schools. The findings suggest that schools perceive psychologists as having a central role to play in the area of learning difficulties but indicate a considerable shortfall between present and desired levels of service. It was also noted that after more than a decade of reconstruction of psychological services in which a major theme has been a reduced emphasis on direct work with individual children, the traditional role of individual assessment and counselling is the one which continues to be strongly endorsed .

The present paper reports a case study of academic staff's perspectives upon student plagiarism at a university in Hong Kong. Based on interviews with 16 instructors, the study focused on the teachers' views and pedagogical practices, including their use of Turnitin. The paper ends by noting certain areas that need to be addressed in tackling student plagiarism and by proposing a few lines of future research.
Upregulation of MicroRNA-15a Contributes to Pathogenesis of Abdominal Aortic Aneurysm (AAA) by Modulating the Expression of Cyclin-Dependent Kinase Inhibitor 2B (CDKN2B)

Background The objective of the present study was to identify the association between miR-15a-5p and CDKN2B, and their roles in regulating the development of abdominal aortic aneurysm (AAA). Material/Methods We searched the miRNA database online (www.mirdb.org) and used a luciferase reporter assay system to study the regulatory relationship between miR-15a-5p and CDKN2B. We also conducted real-time PCR and Western blot analysis to study the mRNA and protein expression level of CDKN2B among different patient groups (participants with abdominal aortic aneurysm (AAA) and normal controls) or cells treated with scramble control, miR-15a-5p mimics, CDKN2B siRNA, and miR-15a-5p inhibitors. Results We found that CDKN2B was a virtual target of miR-15a-5p with potential binding sites in the 3′UTR of CDKN2B (77–83 bp). We also showed that miR-15a-5p could bind to the CDKN2B 3′UTR, resulting in a significant decrease in luciferase activity compared with the scramble control. Furthermore, we found that the cells isolated from AAA participants showed an over-expression of miR-15a-5p compared to the normal controls, while the CDKN2B mRNA and protein expression level of the AAA group were much lower than the normal control group. Additionally, the expression of CDKN2B mRNA and the protein of the cells transfected with miR-15a-5p mimics and CDKN2B siRNA was downregulated, while the cells showed upregulated expression subsequent to transfection with miR-15a-5p inhibitors compared to the scramble control. Conclusions The data revealed a negative regulatory role of miR-15a-5p in the apoptosis of smooth muscle cells via targeting CDKN2B, and showed that miR-15a-5p could be a novel therapeutic target of AAA.
CD8 T cell response and evolutionary pressure to HIV-1 cryptic epitopes derived from antisense transcription

Retroviruses pack multiple genes into relatively small genomes by encoding several genes in the same genomic region with overlapping reading frames. Both sense and antisense HIV-1 transcripts contain open reading frames for known functional proteins as well as numerous alternative reading frames (ARFs). At least some ARFs have the potential to encode proteins of unknown function, and their antigenic properties can be considered as cryptic epitopes (CEs). To examine the extent of active immune response to virally encoded CEs, we analyzed human leukocyte antigen class I–associated polymorphisms in HIV-1 gag, pol, and nef genes from a large cohort of South Africans with chronic infection. In all, 391 CEs and 168 conventional epitopes were predicted, with the majority (307; 79%) of CEs derived from antisense transcripts. In further evaluation of CD8 T cell responses to a subset of the predicted CEs in patients with primary or chronic infection, both sense- and antisense-encoded CEs were immunogenic at both stages of infection. In addition, CEs often mutated during the first year of infection, which was consistent with immune selection for escape variants. These findings indicate that the HIV-1 genome might encode and deploy a large potential repertoire of unconventional epitopes to enhance vaccine-induced antiviral immunity.
‘Mmmmm quanti, ma quanti ricordi mi evocano queste foto ...’: Facebook and the 1977 Family Album: The Digital (R)evolution of a Protest Generation1

Abstract Memories are increasingly shaped and shared through the media, in particular visual media such as photography. However, it is not just the images that allow for memories to enter our individual and collective identities: the latter take shape in the mediation of the past through images. In other words, the very act of selecting, storing, and sharing visual data has an impact on the way the past is recalled and identities are reconstructed in the present. What happens, though, when photo albums go digital, and private snapshots become available to all? This article analyses the collective sharing of a series of photo albums of the 1977 student movement in Bologna, on the social networking site Facebook, in 2011. It explores how the collective (hi)story of the 1977 generation is reproduced online, why this specific medium was so successful in reconnecting these people thirty-five years later, and what the impact is of digital media and social networks on the reconstruction of collective identities in the present.
Interpersonal Proximity in Social and Cognitive Space

We explore how humans solve some problems of living in a social world. In particular, we focus on the ability to see affiliation or alliance patterns in social communities. We draw on data from two naturalistic studies in which subjects were observed interacting and required to reveal their perceptions of the patterning of that interaction. In both cases, the observed interaction patterns and the subjects' reports correspond closely. But in both cases, subjects are shown to simplify and exaggerate the observed patterning. Individual subjects, moreover, appear able to reveal more details about interaction patterns among those with whom they interact frequently, while they gloss over details involving interaction among others with whom their own interaction is infrequent.
Quantifying differences between five fingers in speed-accuracy tradeoff for force control tasks

The differences of force control capability among individual fingers have been studied in a wide range of contexts. However, the quantitative metric in term of the speed-accuracy tradeoff (SAT) between five fingers has not been systematically investigated. In this paper, we aim to explore this question by measuring SAT of each finger in a precision force control task. During the experiment, participants pressed a force sensor using one of the five fingers of the right hand in an immersive scene. They were instructed to maintain a target force with an expected tolerance within an allowable response time in each trial. The performance of the SAT for each finger was measured under different index of difficulty (ID). The experimental data showed that the SAT characteristic of individual fingers was significantly different. The quantifiable differences of the index of performance (IP) among individual fingers were obtained, which may provide a guideline for design of manipulation products or tasks requiring fast and accurate force control using different fingers.
Universals: Studies in Indian Logic and Linguistics

This collection of articles and review essays, including many hard to find pieces, comprises the most important and fundamental studies of Indian logic and linguistics ever undertaken. Frits Staal is concerned with four basic questions: Are there universals of logic that transcend culture and time? Are there universals of language and linguistics? What is the nature of Indian logic? And what is the nature of Indian linguistics? By addressing these questions, Staal demonstrates that, contrary to the general assumption among Western philosophers, the classical philosophers of India were rationalists, attentive to arguments. They were in this respect unlike contemporary Western thinkers inspired by existentialism or hermeneutics, and like the ancient Chinese, Greeks, and many medieval European schoolmen, only as Staal says more so. "Universals" establishes that Asia's contributions are not only compatible with what has been produced in the West, but a necessary ingredient and an essential component of any future human science.

The Scaffolding Adapter Gab2, via Shp-2, Regulates Kit-evoked Mast Cell Proliferation by Activating the Rac/JNK Pathway*

The scaffolding adapter Gab2 mediates cell signaling and responses evoked by various extracellular stimuli including several growth factors. Kit, the receptor for stem cell factor (SCF), plays a critical role in the proliferation and differentiation of a variety of cell types, including mast cells. Kit, via Tyr567 and Tyr719, activates Src family kinases (SFK) and PI3K respectively, which converge on the activation of a Rac/JNK pathway required for mast cell proliferation. However, how Kit Tyr567 signals to Rac/JNK is not well understood. By analyzing Gab2–/– mast cells, we find that Gab2 is required for SCF-evoked proliferation, activation of Rac/JNK, and Ras. Upon Kit activation in wild-type mast cells, Gab2 becomes tyrosyl-phosphorylated and associates with Kit and Shp-2. Tyr567, an SFK binding site in Kit, and SFK activity were required for Gab2 tyrosyl phosphorylation and association with Shp-2. By re-expressing Gab2 or a Gab2 mutant that cannot bind Shp-2 in Gab2–/– mast cells or acutely by deleting Shp-2 in mast cells, we found that Gab2 requires Shp-2 for SCF-evoked Rac/JNK, Ras activation, and mast cell proliferation. Lastly, by analyzing mast cells from mice with compound Gab2 and Kit Y719F mutations (i.e., Gab2–/–: KitY719F/Y719F mice), we find that Gab2, acting in a parallel pathway to PI3K from Kit Tyr719, regulates mast cell proliferation and development in specific tissues. Our data show that Gab2 via Shp-2 is critical for transmitting signals from Kit Tyr567 to activate the Rac/JNK pathway controlling mast cell proliferation, which likely contributes to mast cell development in specific tissues.
