PISCINOODINIUM, A FISH-ECTOPARASITIC DINOFLAGELLATE, IS A MEMBER OF THE CLASS DINOPHYCEAE, SUBCLASS GYMNODINIPHYCIDAE: CONVERGENT EVOLUTION WITH AMYLOODINIUM

All dinoflagellates that infest the skin and gills of fish have traditionally been placed within the class Blastodiniphyceae. Their relatedness was primarily based upon a similar mode of attachment to the host, i.e., attachment disc with holdfasts. Results of recent molecular genetic analyses have transferred these parasites, including Amyloodinium, to the class Dinophyceae, subclass Peridiniphycidae. In our study, a small subunit rDNA gene from a parasitic dinoflagellate that has features diagnostic for species in the genus Piscinoodinium, i.e., typical trophont with attachment disc having rhizocysts, infesting the skin of freshwater tropical fish, places this organism within the dinophycean subclass Gymnodiniphycidae. This suggests a close relationship of Piscinoodinium spp. to dinoflagellates that include symbionts, e.g., species of Symbiodinium, and free-living algae, e.g., Gymnodinium spp. These molecular and morphological data suggest that evolution of this mode of fish ectoparasitism occurred independently in 2 distantly related groups of dinoflagellates, and they further suggest that the taxonomic status of parasites grouped as members of Piscinoodinium requires major revision.
Dissection of the regulatory mechanism of a heat-shock responsive promoter in Haloarchaea: a new paradigm for general transcription factor directed archaeal gene regulation

Multiple general transcription factors (GTFs), TBP and TFB, are present in many haloarchaea, and are deemed to accomplish global gene regulation. However, details and the role of GTF-directed transcriptional regulation in stress response are still not clear. Here, we report a comprehensive investigation of the regulatory mechanism of a heat-induced gene (hsp5) from Halobacterium salinarum. We demonstrated by mutation analysis that the sequences 5′ and 3′ to the core elements (TATA box and BRE) of the hsp5 promoter (Phsp5) did not significantly affect the basal and heat-induced gene expression, as long as the transcription initiation site was not altered. Moreover, the BRE and TATA box of Phsp5 were sufficient to render a nonheat-responsive promoter heat-inducible, in both Haloferax volcanii and Halobacterium sp. NRC-1. DNA–protein interactions revealed that two heat-inducible GTFs, TFB2 from H. volcanii and TFBb from Halobacterium sp. NRC-1, could specifically bind to Phsp5 likely in a temperature-dependent manner. Taken together, the heat-responsiveness of Phsp5 was mainly ascribed to the core promoter elements that were efficiently recognized by specific heat-induced GTFs at elevated temperature, thus providing a new paradigm for GTF-directed gene regulation in the domain of Archaea.
Matrix concentration inequalities via the method of exchangeable pairs

This paper derives exponential concentration inequalities and polynomial moment inequalities for the spectral norm of a random matrix. The analysis requires a matrix extension of the scalar concentration theory developed by Sourav Chatterjee using Stein’s method of exchangeable pairs. When applied to a sum of independent random matrices, this approach yields matrix generalizations of the classical inequalities due to Hoeffding, Bernstein, Khintchine and Rosenthal. The same technique delivers bounds for sums of dependent random matrices and more general matrix-valued functions of dependent random variables.
Use of “Phantom Electrode” Technique to Extend the Range of Pitches Available Through a Cochlear Implant

Objective: The range of pitch sensations available in cochlear implants (CIs) is conventionally thought to be limited by the location of the most apical and basal electrodes. However, partial bipolar stimulation, in which current is distributed to two intracochlear electrodes and one extracochlear electrode, can produce “phantom electrode” (PE) pitch percepts that extend beyond the pitch range available with physical electrodes. The goals of this study were (1) to determine the PE configuration that generated the lowest pitch relative to monopolar (MP) stimulation of the most apical electrode and (2) to determine the amount of pitch shift produced by different PE configurations. Design: Ten Advanced Bionics CI users (9 unilateral and 1 bilateral), implanted with the CII or HiRes 90k implant and the HiFocus 1, HiFocus 1j, or Helix electrode arrays participated in this study. PEs were created by simultaneously stimulating the primary and compensating electrodes in opposite phase. To test different PE configurations, the proportion of current delivered to the compensating electrode (σ) and the electrode separation between the primary and compensatory electrode (D) were varied. To estimate the relative pitch of PEs, the lowest pitched PEs with primary electrodes 4 and 8 were compared with subsets of MP electrodes (1, 2, 3, 4, 5 and 5, 6, 7, 8, 9, respectively). Results: In all subjects, it was possible to identify σ and D values that produced a PE that was lower in pitch than the MP stimulation of the primary electrode. In some subjects, increasing σ and/or D produced progressively lower pitch percepts, whereas in others, PE pitch changed nonmonotonically with σ and/or D. The amount of PE pitch shift could be estimated only for 14 cases; in seven cases, the pitch shift was <1 MP electrode, and in seven other cases, the pitch shift was between 1 and 2 MP electrodes. Conclusions: PE stimulation can elicit pitch percepts lower than that of the most apical MP electrode; the PE pitch is lower by the equivalent of 0.5 to 2 MP electrodes.
Single-Mode Optical Waveguides on Native High-Refractive-Index Substrates

High-refractive-index semiconductor optical waveguides form the basis for modern photonic integrated circuits (PICs) , but the conventional methods of achieving optical confinement require a thick lower-refractive-index support layer that impedes large-scale co-integration with electronics. To address this challenge, we present a general architecture for single-mode waveguides that confine light in a high-refractive-index material on a native substrate. Our waveguide consists of a high-aspect-ratio fin of the guiding material surrounded by lower-refractive-index dielectrics and is compatible with standard top-down fabrication techniques. The proposed waveguide geometry removes the need for a buried-oxide-layer in silicon photonics, as well as the InGaAsP layer in InP-based PICs and will allow for photonic integration on emerging material platforms such as diamond and SiC.
Human Centred Object Co-Segmentation

Co-segmentation is the automatic extraction of the common semantic regions given a set of images. Different from previous approaches mainly based on object visuals, in this paper, we propose a human centred object co-segmentation approach, which uses the human as another strong evidence. In order to discover the rich internal structure of the objects reflecting their human-object interactions and visual similarities, we propose an unsupervised fully connected CRF auto-encoder incorporating the rich object features and a novel human-object interaction representation. We propose an efficient learning and inference algorithm to allow the full connectivity of the CRF with the auto-encoder, that establishes pairwise relations on all pairs of the object proposals in the dataset. Moreover, the auto-encoder learns the parameters from the data itself rather than supervised learning or manually assigned parameters in the conventional CRF. In the extensive experiments on four datasets, we show that our approach is able to extract the common objects more accurately than the state-of-the-art co-segmentation algorithms.
Pattern synonyms

Pattern matching has proven to be a convenient, expressive way of inspecting data. Yet this language feature, in its traditional form, is limited: patterns must be data constructors of concrete data types. No computation or abstraction is allowed. The data type in question must be concrete, with no ability to enforce any invariants. Any change in this data type requires all clients to update their code. This paper introduces pattern synonyms, which allow programmers to abstract over patterns, painting over all the shortcomings listed above. Pattern synonyms are assigned types, enabling a compiler to check the validity of a synonym independent of its definition. These types are intricate; detailing how to assign a type to a pattern synonym is a key contribution of this work. We have implemented pattern synonyms in the Glasgow Haskell Compiler, where they have enjoyed immediate popularity, but we believe this feature could easily be exported to other languages that support pattern matching.
Face Management, Question Wording, and Social Desirability1

Five experiments were conducted to examine the impact of question wording manipulations derived from face management theory (Brown & Levinson, 1987) on responses to survey questions. In general, it was expected that questions phrased so as to allow the respondent to maintain face while answering in a socially undesirable manner would result in lower rates of socially desirable responding than would control questions. The results strongly supported this hypothesis for questions regarding socially desirable knowledge (e.g., Are you familiar with NAFTA? ), but not for questions about socially desirable behavior (e.g., Did you vote? ). The results were partially supportive for questions about socially undesirable behaviors (e.g., Have you ever shoplifted? ).
Treatment of ragweed allergic conjunctivitis with 2% cromolyn solution in unit doses.

Previous studies have shown the effectiveness of topical cromolyn solution in the treatment of allergic conjunctivitis. However, the preservative, phenylethanol, produces an immediate burning or stinging sensation when the drops are first instilled in the eye. A double-blind, crossover, placebo controlled study using 2% cromolyn solution was conducted, without the preservative and supplied in unit doses. Twenty six patients took part in the trial. They had ragweed pollen-induced conjunctivitis. The results of the trial indicate that the active drug was effective in controlling the signs and symptoms of allergic conjunctivitis in 22 of the 26 patients, i.e., 84.6% (p less than 0.001). Two patients preferred the placebo. There were no complaints of stinging or burning sensation after the instillation of the drops in the eyes. There were no cases of infection of the eye. Without the preservative, the cromolyn solution does not damage the soft contact lens.
An Unsupervised Method for Multilingual Word Sense Tagging Using Parallel Corpora

With an increasing number of languages making their way to our desktops everyday via the Internet, researchers have come to realize the lack of linguistic knowledge resources for scarcely represented/studied languages. In an attempt to bootstrap some of the required linguistic resources for some of those languages, this paper presents an unsupervised method for automatic multilingual word sense tagging using parallel corpora. The method is evaluated on the English Brown corpus and its translation into three different languages: French, German and Spanish. A preliminary evaluation of the proposed method yielded results of up to 79% accuracy rate for the English data on 81.8% of the SemCor manually tagged data.
How perpetrators and targets construe knowledge hiding in organizations

Research has begun to document the negative organizational consequences of knowledge hiding, or the intentional attempt to conceal knowledge, among employees. However, different knowledge hiding behaviours exist, and we explore whether some types of knowledge hiding are more harmful than others. Although theory would suggest that knowledge hiders rationalize their behaviours and fail to anticipate the negative consequences of their behaviours, we found that they did anticipate harmed relationships and retaliation. In addition, targets of knowledge hiding did not always construe the behaviour as harmful or as necessitating retaliation. Overall, our research suggests that not all knowledge hiding is equally harmful. Some types of knowledge hiding may actually enhance the relationships between colleagues and might break the cycle of knowledge hiding in organizations.
A system for automatic alignment of broadcast media captions using weighted finite-state transducers

We describe our system for alignment of broadcast media captions in the 2015 MGB Challenge. A precise time alignment of previously-generated subtitles to media data is important in the process of caption generation by broadcasters. However, this task is challenging due to the highly diverse, often noisy content of the audio, and because the subtitles are frequently not a verbatim representation of the actual words spoken. Our system employs a two-pass approach with appropriately constrained weighted finite state transducers (WFSTs) to enable good alignment even when the audio quality would be challenging for conventional ASR. The system achieves an f-score of 0.8965 on the MGB Challenge development set.
“It's Who I Am … Really!’ The Importance of Integrated Regulation in Exercise Contexts1

The purpose of this series of studies was to evaluate a measure of integrated regulation specific to exercise contexts in line with Self-Determination Theory (SDT; Deci & Ryan, 1985, 2002). To address this purpose, three studies were conducted to test select psychometric and theoretical properties of four integrated regulation items created for use within the Behavioural Regulation in Exercise Questionnaire (BREQ). Confirmatory factor analyses conducted in Studies 1 and 2 supported the inclusion of integrated regulation within the expanded BREQ measurement model. Simultaneous multiple regression analyses (SMRAs) conducted in Study 2 indicated that greater need satisfaction promoted endorsement of autonomous exercise motives, including integrated regulation. Finally, SMRA conducted in Study 3 revealed that integrated regulation contributed to the prediction of exercise behavior and physical self-worth. Collectively, the results of this investigation suggest that the new integrated regulation items can be used in conjunction with the BREQ without compromising validity, and support Deci and Ryan's (1985, 2002) assertions regarding the importance of autonomous extrinsic motives, including integrated regulation in exercise domains.
Key semantics extraction by dependency tree mining

We propose a new text mining system which extracts characteristic contents from given documents. We define Key semantics as characteristic sub-structures of syntactic dependencies in the given documents, and consider the following three tasks in this paper: 1)Key semantics extraction: extracting characteristic syntactic dependency structures not only as ordered trees but also as unordered trees and free trees, 2)Redundancy reduction: from the result of extraction, deleting redundant dependency structures such as sub-structures or equivalent structures of the others, and 3)Phrase/sentence reconstruction: generating a phrase or sentence in a natural language corresponding to the extracted structure.Our system is a combination of natural language processing techniques and tree mining techniques. The system consists of the following five units: 1) syntactic dependency analysis unit, 2) input filters, 3) characteristic ordered subtree extraction unit, 4) output filters, and 5) phrase/sentence reconstruction unit. Although ordered trees are extracted in the third unit, the overall behavior of the system can be switched into the extraction of ordered trees, unordered trees, or free trees depending on which of the input filters is/are applied in the second step. The output filters delete redundant trees from the extraction result for efficient knowledge discovery. Finally, phrases or sentences corresponding to the extracted subtrees are reconstructed by utilizing the input documents.We demonstrate the validity of our system by showing experimental results using real data collected at a help desk and TDT pilot corpus.
Understanding web 2.0’s influences on public e-services: a protection Motivation perspective

Abstract Web 2.0 offers both technology and an environment that facilitates transparency and communication for users and stakeholders. With this opportunity, public sector e-services are given tools to engage their own employees in an atmosphere that not only fosters new ideas, but provides a framework for managing prototypes and pilot projects that encourage experimentation. In addition, this environment encourages collaboration and breaking down walls of information asymmetries between various stakeholders. Public sector e-services has a legacy of a risk adverse environment where many times the focus is on the politically charged short-term delivery of goals and results, lacking a long-term strategy of managing the risk and renewal cycle around service innovation. The promises and potential that Web 2.0 technologies may provide still have to deal with fragile systems that are currently in place in public sector e-services. Government regulators, consumer advocacy groups, and e-services need to understand how Internet innovation affects the end user/consumer directly. The central premise being that these groups are modeling consumer trends and may be making decisions on false or fabricated information, even suggesting this could lead to inhibiting overall Internet innovation.
Establishing Special Education Programs: Experiences of Christian School Principals

This phenomenological study investigated the experiences of principals who initiated special education programs in Christian schools. Principals described efforts involved to effect changes in the school and noted difficulties in dealing with reluctant staff members. Principals described academic and social rewards of providing services and the satisfaction of parents who found it possible to send their children with special needs to a Christian school. A prominent theme evidenced in this study was the spiritual change in the school as all students interacted and cared for each other.
Analysis of ischemia‐reperfusion injury in a microcirculatory model of pressure ulcers

The aim of this study was to establish a pressure ulcer model that visualizes the microcirculation, and to examine the participation of ischemia‐reperfusion injury in the pathophysiology of pressure ulcers. An original system composed of a new skin fold chamber and compression device allowed loading quantitative vertical stress to the skin. An intravital microscopic technique enabled direct visualization of the microcirculation in the physiological condition and in response to pressure application. To estimate the effect of ischemia‐reperfusion injury, animals were divided into two groups: the compression‐release group (n = 8), in which the animals received four cycles of compression‐release which consisted of 2 hours of compression followed by 1 hour of pressure release; and the compression alone group (n = 8) in which the animals underwent continuous compression for 8 hours. Functional capillary density was quantified before the compression procedure and on day 1 (35 hours) after the first evaluation. The cyclic compression‐release procedure significantly decreased functional capillary density as compared to continuous compression, indicating that in our experimental setting repetition of ischemia‐reperfusion cycle more severely damaged the microcirculation than single prolonged ischemic insult. This finding supports the significant contribution of ischemia‐reperfusion injury to the pathophysiology of pressure ulcers at the level of dynamic in vivo microcirculation.
Evaluation of frequency band technique in estimating muscle fatigue during dynamic contraction task

Long-time exposure to repetitive or monotonous work is associated with increased risk for musculoskeletal disorders that are due to muscle fatigue. Previously, researchers reported that muscle fatigue can be estimated using a low-frequency band of an SEMG signal. However, these studies were performed exclusively during static contraction tasks. The objective of the present study was to evaluate and determine the frequency range for a low-frequency band. In addition, the performance during dynamic contraction tasks was analyzed. A group of healthy university students (8 males) was recruited, and endurance handgrip tasks were conducted. SEMG signals were captured from the forearm muscle. The frequency range for the low-frequency band was redefined as 5 – 40Hz. The results from a dynamic contraction task indicated that a low-frequency band is a reliable method for indexing muscle fatigue from SEMG signals.
Immunotherapy of an ascitic rat hepatoma with cord factor (trehalose‐6, 6′‐dimycolate) and synthetic analogues

The ability of cord factor (trehalose‐6, 6′‐dimycolate) and a range of shorter carbon chain fatty acid trehalose diesters to suppress growth of an ascitic rat hepatoma has been examined and compared with that of whole, living BCG organisms. Aqueous suspensions of BCG, and cord factor in 0.4% arachis oil:Triton emulsion, injected intra‐peritoneally, retarded growth of up to 105 ascites tumour cells. Trehalose‐6, 6′‐dibehenate was also tumour‐suppressive, but only against lower challenge inocula (104 cells). Trehalose‐6, 6′‐dipalmitate and 6,6′‐di‐0–2‐tetradecyl ‐3‐hydroxyoctadecanoyl β,β trehalose (designated C76) were virtually ineffective and 6,6′ ‐di‐0–2‐eicosyl‐3‐hydroxy‐tetracosanoyl β, β trehalose (designated C100) gave small and variable effects only against low challenge inocula. However, improved responses were seen with light mineral oil in place of arachis oil in the emulsions.
Stress at work: psychobiological and psychosocial aspects1

This article outlines our approach to the issue of stress, coping and health as related to the psychosocial work environment. We have focused on work processes and work organization related to different applications of technology. It is by now generally recognized that mechanization and automation may result not only in improved productivity, but may also have negative side effects at the human level (e.g., Gardell and Johansson, 1981; Levi et al., 1982). We are trying to identify these aversive factors. Moreover, we want to identify the protective factors, by which we mean psychosocial conditions, which may serve as buffers protecting the person from harmful stress effects. In other words, we are asking the question how research on human stress and coping can contribute to intervention and prevention, not only at the individual level but also at the systems level (Frankenhaeuser, 1981).
London calling: selection as pre‐emptive strategy for cultural control

Purpose – This article seeks to explore forms of selection practice, focusing on role‐play techniques, which have been introduced in many organizations in an attempt to “objectivize” the selection process by offering a means of assessing task‐specific aptitudes.Design/methodology/approach – This article draws upon an ethnographic study of a call centre in which the researcher underwent the recruitment and selection process to secure work as a precursor to conducting fieldwork within the organization. Whilst there is little precedent for the employment of ethnographic techniques in researching recruitment and selection, we argue such techniques are appropriate to explore the social processes involved in practices such as role‐play. The discussion draws upon fieldwork which was conducted at “CallCentreCo”, who continuously recruit customer service representatives (CSRs) to work in their call centre. CallCentreCo uses role‐playing exercises extensively in the selection of all grades of staff and are argued b.
