Satisfaction as Mediators Demand-Withdraw Communication Pattern and Relationship Adult Attachment and Male Aggression in Couple Relationships: The

This study examines men’s domestic aggression as a function of attachment insecurities, considering the mediating roles of the demand-withdraw communication pattern and relationship satisfaction. The sample included 55 Canadian men undergoing counseling for relationship difficulties including aggression. The men completed questionnaires assessing physical and psychological aggression, the two dimensions of attachment insecurity (anxiety over abandonment and avoidance of intimacy), the demand-withdraw communication pattern, relationship satisfaction, and social desirability (a control 1Université de Sherbrooke, Québec, Canada 2University of California, Davis Corresponding Author: Audrey Brassard, Department of Psychology, Université de Sherbrooke, 2500, boul.

As predicted, there was an association between attachment anxiety and aggression (both physical and psychological), which was mediated by the man demands/woman withdraws (MD/WW) pattern (as reported by the men). There was no evidence of mediation by the woman demands/man withdraws pattern, as reported by the men. Relationship satisfaction mediated the association between attachment anxiety and psychological (but not physical) aggression, but did not mediate the link between avoidance and aggression (physical or psychological). Limitations and clinical implications are discussed.
High-density lipoprotein inhibits mechanical stress-induced cardiomyocyte autophagy and cardiac hypertrophy through angiotensin II type 1 receptor-mediated PI3K/Akt pathway

Mechanical stress triggers cardiac hypertrophy and autophagy through an angiotensin II (Ang II) type 1 (AT1) receptor‐dependent mechanism. Low level of high density lipoprotein (HDL) is an independent risk factor for cardiac hypertrophy. This study was designed to evaluate the effect of HDL on mechanical stress‐induced cardiac hypertrophy and autophagy. A 48‐hr mechanical stretch and a 4‐week transverse aortic constriction were employed to induce cardiomyocyte hypertrophy in vitro and in vivo, respectively, prior to the assessment of myocardial autophagy using LC3b‐II and beclin‐1. Our results indicated that HDL significantly reduced mechanical stretch‐induced rise in autophagy as demonstrated by LC3b‐II and beclin‐1. In addition, mechanical stress up‐regulated AT1 receptor expression in both cultured cardiomyocytes and in mouse hearts, whereas HDL significantly suppressed the AT1 receptor. Furthermore, the role of Akt phosphorylation in HDL‐mediated action was assessed using MK‐2206, a selective inhibitor for Akt phosphorylation. Our data further revealed that MK‐2206 mitigated HDL‐induced beneficial responses on cardiac remodelling and autophagy. Taken together, our data revealed that HDL inhibited mechanical stress‐induced cardiac hypertrophy and autophagy through downregulation of AT1 receptor, and HDL ameliorated cardiac hypertrophy and autophagy via Akt‐dependent mechanism.
Integration of time series models with soft clustering to enhance network traffic forecasting

The network traffic forecasting is of significant interest in many domains such as bandwidth allocation, congestion control and network management. Hence, forecasting of network traffic has received attention from the computer networks field for achieving guaranteed Quality of Service (QoS) in network. In this paper, we propose a forecasting model that combines conventional time series models with clustering approaches. The conventional linear and non linear time series models namely Weighted Exponential Smoothing (WES), Holt-Trend Exponential Smoothing (HTES), AutoRegressive Moving Average (ARMA), Hybrid model (Wavelet with WES) and AutoRegrssive Neural Network (NARNET) models are applied for forecasting network traffic. Our novelty is application of soft clustering for enhancing the existing time series models that are used to forecast network traffic. Clustering can model network traffic data and its characteristics. We derived a methodology to appropriately use cluster centriods to enhance the results obtained by conventional approach. We experimented with different soft clustering techniques such as Fuzzy C-Means (FCM) and Rough K-Means (RKM) clustering to verify the improvement in forecasting. The results of our integrated model are validated using Mean Square Error (MSE), Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) performance measures. The results show that the integrated model enhances the results obtained using conventional time series forecasting models.
The Role of Interstitial Sites in the Ti3d Defect State in the Band Gap of Titania

Titanium dioxide (TiO2) has a number of uses in catalysis, photochemistry, and sensing that are linked to the reducibility of the oxide. Usually, bridging oxygen (Obr) vacancies are assumed to cause the Ti3d defect state in the band gap of rutile TiO2(110). From high-resolution scanning tunneling microscopy and photoelectron spectroscopy measurements, we propose that Ti interstitials in the near-surface region may be largely responsible for the defect state in the band gap. We argue that these donor-specific sites play a key role in and may dictate the ensuing surface chemistry, such as providing the electronic charge required for O2 adsorption and dissociation. Specifically, we identified a second O2 dissociation channel that occurs within the Ti troughs in addition to the O2 dissociation channel in Obr vacancies. Comprehensive density functional theory calculations support these experimental observations.
Novel Roles of Formin mDia2 in Lamellipodia and Filopodia Formation in Motile Cells

Actin polymerization-driven protrusion of the leading edge is a key element of cell motility. The important actin nucleators formins and the Arp2/3 complex are believed to have nonoverlapping functions in inducing actin filament bundles in filopodia and dendritic networks in lamellipodia, respectively. We tested this idea by investigating the role of mDia2 formin in leading-edge protrusion by loss-of-function and gain-of-function approaches. Unexpectedly, mDia2 depletion by short interfering RNA (siRNA) severely inhibited lamellipodia. Structural analysis of the actin network in the few remaining lamellipodia suggested an mDia2 role in generation of long filaments. Consistently, constitutively active mDia2 (ΔGBD-mDia2) induced accumulation of long actin filaments in lamellipodia and increased persistence of lamellipodial protrusion. Depletion of mDia2 also inhibited filopodia, whereas expression of ΔGBD-mDia2 promoted their formation. Correlative light and electron microscopy showed that ΔGBD-mDia2–induced filopodia were formed from lamellipodial network through gradual convergence of long lamellipodial filaments into bundles. Efficient filopodia induction required mDia2 targeting to the membrane, likely through a scaffolding protein Abi1. Furthermore, mDia2 and Abi1 interacted through the N-terminal regulatory sequences of mDia2 and the SH3-containing Abi1 sequences. We propose that mDia2 plays an important role in formation of lamellipodia by nucleating and/or protecting from capping lamellipodial actin filaments, which subsequently exhibit high tendency to converge into filopodia.
An Examination of Motivational Levels of Non-Traditional Undergraduate Business and Education Majors

This research dissertation was developed for the purpose of advancing the literature in the realm of student motivation. Previous research in the field has placed little emphasis on the adult, nontraditional student population. Adult, non-traditional students represents an important part of the higher education climate in the United States and the unique motivators of this population needs further examination in order to more closely align academic programs and services with motives and goals. The research questions seek to answer if a significant difference exists between the intrinsic and extrinsic motivational levels of business majors compared to education majors in the adult, non-traditional student population. This research study will employ a causal-comparative design using a Likert instrument to explore the motivational levels of non-traditional undergraduate students. The two research questions for this study include: Is there a difference in the intrinsic motivational levels of non-traditional undergraduate business majors when compared to the intrinsic motivational levels of non-traditional undergraduate; is there a difference in the extrinsic motivational levels of non-traditional undergraduate business majors when compared to the extrinsic motivational levels of non-traditional undergraduate education majors? The methods employed include the use of the previously validated instrument, the Academic Motivation Scale, which has been used in similar studies focused on different populations for the purpose of identifying motivational levels in students. The sample size for the study included 110 subjects and a simple, independent samples t test was deployed during the analysis. The results of the study demonstrate significant differences between non-traditional business and education majors on both the intrinsic and extrinsic measurements.
The plantaris tendon and a potential role in mid‐portion Achilles tendinopathy: an observational anatomical study

The source of pain and the background to the pain mechanisms associated with mid‐portion Achilles tendinopathy have not yet been clarified. Intratendinous degenerative changes are most often addressed when present. However, it is questionable if degeneration of the tendon itself is the main cause of pain. Pain is often most prominent on the medial side, 2–7 cm from the insertion onto the calcaneus. The medial location of the pain has been explained to be caused by enhanced stress on the calcaneal tendon due to hyperpronation. However, on this medial side the plantaris tendon is also located. It has been postulated that the plantaris tendon might play a role in these medially located symptoms. To our knowledge, the exact anatomy and relationship between the plantaris‐ and calcaneal tendon at the level of complaints have not been anatomically assessed. This was the purpose of our study. One‐hundred and seven lower extremities were dissected. After opening the superficial fascia and paratendon, the plantaris tendon was bluntly released from the calcaneal tendon moving distally. The incidence of the plantaris tendon, its course, site of insertion and possible connections were documented. When with manual force the plantaris tendon could not be released, it was defined as a ‘connection’ with the calcaneal tendon. In all specimens a plantaris tendon was identified. Nine different sites of insertion were found, mostly medial and fan‐shaped onto the calcaneus. In 11 specimens (10%) firm connections were found at the level of the calcaneal tendon mid‐portion. Clinical and histological studies are needed to confirm the role of the plantaris tendon in mid‐portion Achilles tendinopathy.
Choosing fast and slow: explaining differences between hedonic and utilitarian choices

This paper examines the psychological differences between hedonic and utilitarian patterns of preference behavior. Instead of using latent variables like self-control and emotion to explain these differences, we show that they emerge as natural consequences of solving two different, but related problems within an inductive framework of preference learning. We show that hedonic decisions involve tracking the variability of a binary variable, whereas utilitarian decisions require the maintenance of a distribution over a vector of object labels. Computational experiments show that this difference in cognitive representation ensures that hedonic decisions have a lower cognitive sampling cost, which makes them less effortful. Further experiments reveal differences in error rates as a function of deliberative effort between the two paradigms. Deliberative effort benefits utilitarian choices, but not hedonic ones. Overall, our work demonstrates the critical role of cognitive representations in extracting strikingly different behavior patterns from simple models of information processing.
Poly(n-butylcyanoacrylate) nanoparticles for oral delivery of quercetin: preparation, characterization, and pharmacokinetics and biodistribution studies in Wistar rats

Background Quercetin (QT) is a potential bioflavonol and antioxidant with poor bioavailability and very low distribution in the brain. A new oral delivery system comprising of poly(n-butylcyanoacrylate) nanoparticles (PBCA NPs) was introduced to improve the oral bioavailability of QT and to increase its distribution in the brain. Physicochemical characteristics, in vitro release, stability in simulated gastric fluid and intestinal fluids, and pharmacokinetics and biodistribution studies of QT-PBCA NPs coated with polysorbate-80 (P-80) were investigated. Objective This study aimed to investigate the physicochemical characteristics, in vitro release, stability in simulated gastric fluid and intestinal fluids, and pharmacokinetics and biodistribution studies of QT-PBCA NPs coated with polysorbate-80 (P-80). Results The results showed that QT-PBCA NPs and QT-PBCA NPs coated with P-80 (QT-PBCA+P-80) had mean particle sizes of 161.1±0.44 nm and 166.6±0.33 nm respectively, and appeared spherical in shape under transmission electron microscopy. The mean entrapment efficiency was 79.86%±0.45% for QT-PBCA NPs and 74.58%±1.44% for QT-PBCA+P-80. The in vitro release of QT-PBCA NPs and QT-PBCA+P-80 showed an initial burst release followed by a sustained release when compared to free QT. The relative bioavailability of QT-PBCA NPs and QT-PBCA+P-80 enhanced QT bioavailability by 2.38- and 4.93-fold respectively, when compared to free QT. The biodistribution study in rats showed that a higher concentration of QT was detected in the brain after the NPs were coated with P-80. Conclusion This study indicates that PBCA NPs coated with P-80 can be potential drug carriers for poorly water-soluble drugs. These NPs were observed to improve the drugs’ oral bioavailability and enhance their transport to the brain.
Interpersonal stressors in the schoolyard and depressive symptoms among Chinese adolescents: The mediating roles of rumination and co-rumination

Stressors have been identified as significant vulnerability factors in the development of adolescents’ depression. The present study focused on the relationship between depressive symptoms and two types of interpersonal stressors in the schoolyard, namely teacher-student interaction stressors (TSIS) and peer interaction stressors (PIS). More importantly, rumination and co-rumination were examined as two possible mechanisms to account for these relationships. A convenience sample of 570 Chinese adolescents aged from 12- to 19-years-old participated in this research. Results indicated that TSIS and PIS were significantly related to participants’ depressive symptoms. Furthermore, rumination partially mediated the relationship between PIS and depressive symptoms. Co-rumination was a partial mediator between both types of interpersonal stressors and depressive symptoms. Hence, rumination and co-rumination might serve as two mechanisms linking interpersonal stressors in the schoolyard and depressive mood in adolescence. The findings are discussed in the light of related literature and potential implications for school practitioners.
Proactive Data Dissemination in Wireless Sensor Networks with Uncontrolled Sink Mobility

This paper investigates Wireless Sensor Networks (WSNs) with mobile sinks that collect data from sensors by following uncontrolled trajectories. In particular, the paper focuses on proactive data dissemination strategies in which the trajectory of the mobile sink is unknown to the sensors. These strategies attempt to obtain a good trade-off between the number of sensors the mobile sinks has to visit in order to collect representative data of all sensors, and the communication effort required by the sensors. All the investigated techniques also avoid the use of multi-hop routing, due to its high cost. Some of them are based on random walks whereas others are based on a combination of probabilistic forwarding and probabilistic storage. An analysis of the various methods in terms of the performance trade-off between the efficiency of the data gathering and communication overhead is also presented.
Radio source contamination of the Sunyaev-Zeldovich effect in galaxy clusters

By cross-correlating the 1.4 GHz FIRST catalog of radio sources with the Abell cluster catalog we have found an excess surface density by a factor � 5 of radio sources within a projected distance, rp, of 0.1 Mpc (for h = 0.65) from the cluster center. The profile of the excess density can be described, for rp > 0. 1M pc, by aβ-model with a core radius of � 0.70 Mpc and β = 1.65. The luminosity function of cluster sources does not show hints of cosmological evolution over the redshift range (z < 0.4) covered by our cluster sample. The mean luminosity function is in excellent agreement with the recent determination by Reddy & Yun (2003) for 7 nearby clusters and extends it by two orders of magnitude to higher luminosities. Its shape is very similar to that of the local luminosity function of field galaxies, but the space density is about 3000 times higher. When extrapolated to 30 GHz, our luminosity function compares very favourably with an estimate obtained directly from the 30 GHz observations by Cooray et al. (1998). The antenna temperature contributed by radio sources within the nominal cluster radius of 1.7 Mpc is estimated to be � 13.5 µK at 30 GHz for clusters at z � 0 and decreases to � 3.4 µ Ka tz � 0.5, in the absence of cosmological evolution; it increases by a factor of � 1.5 within 0.25 Mpc from the cluster center. If the pure luminosity evolution models by Dunlop & Peacock (1990) are adopted, the radio source antenna temperature turns out to be essentially independent of redshift.
German Dialect Identification in Interview Transcriptions

This paper presents three systems submitted to the German Dialect Identification (GDI) task at the VarDial Evaluation Campaign 2017. The task consists of training models to identify the dialect of Swiss-German speech transcripts. The dialects included in the GDI dataset are Basel, Bern, Lucerne, and Zurich. The three systems we submitted are based on: a plurality ensemble, a mean probability ensemble, and a meta-classifier trained on character and word n-grams. The best results were obtained by the meta-classifier achieving 68.1% accuracy and 66.2% F1-score, ranking first among the 10 teams which participated in the GDI shared task.
Applying summarization techniques for term selection in relevance feedback

Query-expansion is an effective Relevance Feedback technique for improving performance in Information Retrieval. In general query-expansion methods select terms from the complete contents of relevant documents. One problem with this approach is that expansion terms unrelated to document relevance can be introduced into the modified query due to their presence in the relevant documents and distribution in the document collection. Motivated by the hypothesis that query-expansion terms should only be sought from the most relevant areas of a document, this investigation explores the use of document summaries in query-expansion. The investigation explores the use of both context-independent standard summaries and query-biased summaries. Experimental results using the Okapi BM25 probabilistic retrieval model with the TREC-8 ad hoc retrieval task show that query-expansion using document summaries can be considerably more effective than using full-document expansion. The paper also presents a novel approach to term-selection that separates the choice of relevant documents from the selection of a pool of potential expansion terms. Again, this technique is shown to be more effective that standard methods.
Expression of the trxC Gene of Rhodobacter capsulatus: Response to Cellular Redox Status Is Mediated by the Transcriptional Regulator OxyR

ABSTRACT Despite the importance of thioredoxins in cellular functions, little is known about the regulation of trx genes. To understand the molecular mechanisms involved in the regulation of the Rhodobacter capsulatus trxC gene, the expression of this gene was investigated. We describe OxyR-dependent redox regulation of the trxC gene that adjusts the levels of thioredoxins in the cell.
There is no opposition between Formal and Cognitive Semantics

Abstract 1. Introduction The history of modern semantics is characterised by two research traditions which are based on radically different views concerning both conceptual motivation and the purpose of semantic research. Realistic semantics conceives of semantics as characterising the relationsship between linguistic expressions and reality. In most cases this relationship is explicated by means of modeltheoretic concepts. The following quote from one of the founding fathers of realistic semantics clearly rejects a mentalist stance.
Social Networks and Career Outcomes

Social capital theory predicts that individuals tend to establish social ties on the basis of homophily, i.e., affinities for similar others. In this paper, we exploit a unique dataset of biographical data for the entire population of executive appointments in German banks for the period 1993-2008, over 10,900 person-year observations, to analyze how social ties among individuals affect career outcomes. We measure social ties among executives based on similarities along four dimensions: age, education, gender, and employment history, and test three hypotheses. First, we examine if better social connectedness increases the probability of appointing outside candidates, i.e., those without a previous employment at the bank, compared to inside candidates. Our empirical results show that social ties based on age differences and gender indeed raise the chance of being appointed significantly for outsiders, whereas similar educational backgrounds serve as barrier to appointment. Second, we propose that career success, measured by the number of executive appointments over the entire career, is positively related to executives' embeddedness in the social system of executives in the industry. We find that the total number of contacts that an executive accumulated is a strong predictor for the number of repeated outside appointments. Third, we hypothesize that executive tenure increases with better social connections. The findings indeed suggest that small age differences increase tenure.
A Joint MLSD Receiver for Meteor Burst Communication

According to the characteristics of meteor burst channels, variable rate data transmission is often employed to improve the average system throughput, and the time-varying meteor channel in the presence of multi-path rays brings difficulties in both data detection and channel estimation at the receiver. As we know, per-survivor processing (PSP) based on the joint data and channel estimation of maximum likelihood sequence detection (MLSD) is often considered to obtain the optimal detection performance for time-varying channels. However, the great computational complexity of PSP is the major problem in practice. In this paper we propose an adaptive state reduction of PSP (ASRP) algorithm with few states in the trellis diagram for exponential decay of meteor channels. Based on the estimation of the meteor channel parameters, the adaptive threshold is derived to select the states close to the right one in the trellis to reduce the complexity of PSP. Theoretical analysis and computer simulations results show that the ASRP we proposed provides suboptimal performance and makes good tradeoff between the performance and the computational complexity, so that the reliable data transmission can be realized for MBC systems with adaptive modulation and coding (AMC).
