Easily Liked and Disliked?: Formation and Change of Implicit and Explicit Attitudes towards One`s Group

People’s attitudes are at the center of social relations and to the heart of the dynamics of social processes. Attitudes are rarely idiosyncratic, but more often they are grounded in the groups we belong to. During the last two decades, research on intergroup attitudes has been enriched by indirect measures assessing spontaneous (implicit) attitudes that are distinguished from controlled (explicit) ones. Whereas explicit attitudes can form and change quickly, implicit attitudes are assumed to stem from long-term experiences and to be resistant to change (Greenwald & Banaji, 1995; Wilson, Lindsey, & Schooler, 2000). However, there is accumulating evidence that implicit attitudes in general and towards social groups in particular can form quickly based on descriptive information (Gregg, Seibt, & Banaji, 2006) or mere group membership (e.g., Otten & Moskowitz, 2000). Concerning the malleability of attitudes towards social groups, empirical evidence is diverse (see Blair, 2002 for the malleability of implicit attitudes; and Gregg et al., for their stability). Recent theorizing takes the diverse findings on the relative malleability of implicit and explicit attitudes into account and addresses their underlying processes and operating systems (e.g., Gawronski & Bodenhausen, 2006; Petty, Brinol, & DeMarree, 2007). It is still an ongoing debate why and when attitudes generally form and change (Gawronski & Sritharan, 2010). Specifically little attention has been paid to the influence of group membership on forming and changing intergroup attitudes.
Decreasing the Localization Error in Border Areas of Sensor Networks

The centroid localization scheme is a very efficient and resource aware algorithm to estimate a position. On a sensor node, the precision of the position depends on the number of different beacons positions the node receives. In networks with a small transmission range, the localization error behaves very balanced over the whole network. But in very large sensor networks with high transmission ranges, the localization error behaves very unsteady and is increased in most border regions of the network. This paper presents a new algorithm Centroid Localization with Edge Correction (CLwEC) to decrease the localization error in border regions of a network significantly
TRECVid 2013 Semantic Video Concept Detection by NTT-MD-DUT

In this report, we describe the approaches and experiments on TRECVid 2013 video concept detection conducted by NTT Media Intelligence Laboratories in collaboration with Dalian University of Technology. For this year’s task, we focused our efforts on two aspects. For the first aspect, we investigated the state-of-the-art machine learning algorithm and feature representation for large-scale concept classifiers construction. Specifically, we first evaluated a newly developed powerful image representation which has been successfully adopted in other visual classification task, i.e., Fisher Vector, for concept detection. Meanwhile, we are also interested in the using of deep learning technique for video classification, and to this end, we have tested various settings of deep learning and the results are reported. For the second aspect, we followed the subspace partition based framework we proposed in our last year work and to balance the precision and efficiency, we proposed a sparse soft-clustering method for ensemble learning, which can get the optimal replication parameter. We conducted experiments on TRECVid SIN task evaluation dataset and submitted 4 runs based on the above methods.
ad -NILPOTENT b -IDEALS IN sl ( n ) HAVING A FIXED CLASS OF NILPOTENCE: COMBINATORICS AND ENUMERATION

We study the combinatorics of ad -nilpotent ideals of a Borel subalgebra of sl ( n +1 , C ). We provide an inductive method for calculating the class of nilpotence of these ideals and formulas for the number of ideals having a given class of nilpotence. We study the relationships between these results and the combinatorics of Dyck paths, based upon a remarkable bijection between ad -nilpotent ideals and Dyck paths. Finally, we propose a ( q,t )-analogue of the Catalan number C n . These ( q,t )-Catalan numbers count, on the one hand, ad -nilpotent ideals with respect to dimension and class of nilpotence and, on the other hand, admit interpretations in terms of natural statistics on Dyck paths.
Trust Propagation Model in Pervasive Computing Environment

Trust is the fundamental building blocks in pervasive computing environment. In many ubiquitous application systems, trust quantification and propagation are the key issues to build successful architectures. According to the need of pervasive computing, some current trust propagation models are analyzed. In order to solve those problems, a definition of trust strength is proposed. And an improved parallelization algorithm is presented. A novel trust propagation model based on recommendation is proposed. Finally, a simulation testbed is built up to examine the trust propagation model.
Multi-Agent System for Market Based Microgrid Operation in Smart Grid Environment

Enabling electricity markets is one of main characteristics of a smart grid that integrates advanced sensing technologies, control methodologies, and communication technologies into current power distribution systems. Intelligent Multi-Agent System (MAS) that provides platform for modeling autonomous decision making entities in de-centralized fashion can be used to implement market based power system operation in smart grid. This paper presents development, and simulation of an intelligent multi-agent system based on IEEE FIPA (Foundation for Intelligent Physical Agents) standards in context of distributed smart grid. In particular, a multiagent system is developed, and simulated for the market based operation of a microgrid in both islanded and grid-connected modes. Microgrid is an innovative control and management architecture at power distribution network, which makes easy to implement smart grid techniques. The simulation outcome shows that the proposed multi-agent system is an excellent platform for facilitating smart operation of microgrids.
NVP-BEZ235 overcomes gefitinib-acquired resistance by down-regulating PI3K/AKT/mTOR phosphorylation

Background Patients harboring activating mutations in epidermal growth factor receptors (EGFR) are particularly sensitive to EGFR tyrosine kinase inhibitors (TKIs). However, most patients develop an acquired resistance after a period of about 10 months. This study focuses on the therapeutic effect of NVP-BEZ235, a dual inhibitor of phosphatidylinositol-3-kinase/mammalian target of rapamycin (PI3K/mTOR), in gefitinib-resistant non-small cell lung cancer. Methods H1975 cell line was validated as a gefitinib-resistant cell model by the nucleotide-sequence analysis. We used the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to detect the growth of H1975 cell line in vitro. H1975 cells’ migration was detected by the migration assay. Xenograft models were used to investigate the growth of gefitinib-resistant non-small cell lung cancer in vivo. Western blot and immunohistochemical analysis were used to investigate the level of PI3K/protein kinase B(AKT)/mTOR signaling pathway proteins. Results We show that NVP-BEZ235 effectively inhibited the growth of H1975 cells in vivo as well as in vitro. Similarly, H1975 cell migration was reduced by NVP-BEZ235. Further experiments revealed that NVP-BEZ235 attenuated the phosphorylation of PI3K/AKT/mTOR signaling pathway proteins. Conclusion Taken together, we suggest that NVP-BEZ235 inhibits gefitinib-resistant tumor growth by downregulating PI3K/AKT/mTOR phosphorylation.
Eliminating implicit dependencies in component models

A software component is defined as a unit of composition with contractually specified interfaces and explicit dependencies that may be independently deployed. Components form generic, re-usable software building blocks, which can be composed into applications and deployed by third parties. A good component model therefore must seek to minimize implicit dependencies in order to maximize re-use and composability. The benefits of component models have led to their widespread application in the area of networked embedded systems and particularly Wireless Sensor Networks. This paper first classifies and analyses the types of dependency that a component may be subject to. Next, we assess the success of contemporary component models in eliminating implicit dependencies and promoting re-usability. We then describe our efforts to reduce implicit distributed dependencies in the design of LooCI: the Loosely-coupled Component Infrastructure. We conclude with a call-to-arms for the component-based software engineering community that suggests avenues for future work.
A Recursive Perspective on Discursive Legitimation and Organizational Action in Mergers and Acquisitions

This paper challenges the predominant view that legitimation is merely a specific phase in merger or acquisition processes. We argue that a better understanding of postmerger organizational dynamics calls for conceptualization of discursive legitimation as an inherent part of unfolding merger processes. In particular, we focus on the recursive relationship between legitimation and organizational action. We have two objectives: to outline a theoretical model that helps one to understand the dynamics of discursive legitimation and organizational action in postmerger organizations, and to examine a revealing case to distinguish the inherent risks and problems in discursive legitimation. Our case analysis focuses on the merger between the French pharmaceutical companies BioMerieux and Pierre Fabre. We adopt a critical multimethod approach and distinguish specific discursive dynamics and pathological tendencies in this case. The analysis highlights the unintended consequences of discursive legitimation, the central role of sensegiving and sensehiding in discursive legitimation, the inherently political nature of legitimation and the risks associated with politicization, the special problems associated with fashionable discourses and the role of the media, the use of specific discursive strategies for legitimation and delegitimation, and the crucial role of actual integration results. This analysis adds to the existing research on mergers and acquisitions by treating discursive legitimation as part of the merger dynamics. In particular, our case analysis provides a new explanation for merger failure. We also believe that the recursive model connecting discursive legitimation and delegitimation strategies to concrete organizational action makes a more general contribution to our understanding of organizational legitimation.
Role of PONs with the conventional communication systems used in today's smart- and MicroGrids

This is a short review about potential use of optical communications and related technologies in smart- and MicroGrids. The application of Passive Optical Networks (PONs) as a telecommunication system for Smart Grids (SGs) and MGs was studied in details from the perspectives of basic architecture, main advantages, and protection schemes. The comparison of PONs with the conventional communication systems used in today's smart grids (IEC 61850 and DNP3) is presented. The purpose of this study is to identify the emerging telecommunication technologies for their potential applications in Smart- and MicroGrids.
Relations of Intimal‐Medial Thickness Among Sites Within the Carotid Artery as Evaluated by B‐Mode Ultrasound

Background and Purpose B-mode ultrasound is a widely used technique for the clinical and epidemiological assessment of carotid atherosclerosis. This article describes the relation between arterial intimal-medial thickness (IMT) at different sites within the extracranial carotid artery. Methods IMT was measured by B-mode real-time ultrasound as an index of atherosclerotic involvement in the extracranial carotid arteries as part of the population-based Atherosclerosis Risk in Communities (ARIC) study. The relation between IMT at different sites was described by correlation coefficients and percentile regression techniques based on between 4034 and 9386 pairs of measurements (variation in sample size depending on the paired sites). Results Increased IMT at one site was associated with increased IMT at other sites. The correlation between right and left IMT at the same anatomic location in the carotid artery ranged from.34 to.49; the correlation at different anatomic locations in the carotid artery on the same side ranged from.25 to.43. The distribution of IMT, described by the percentiles of IMT at the inference site as a function of IMT at the index site, showed constricted percentiles of IMT at the inference site for small IMT at the index site and an increase in the spread of percentiles with increasing IMT. Conclusions Although increased carotid IMT at one site is positively associated with thickened walls at other carotid sites, the ability to accurately predict wall thickness at a site given the wall thickness at other sites is modest. The general association between sites supports the systemic nature of atherosclerosis, while the lack of tight agreement between sites supports the focal nature of the atherosclerotic process.
Are Mortality Rates for Different Operations Related?: Implications for Measuring the Quality of Noncardiac Surgery

Background:Except in cardiac surgery, measuring quality with procedure-specific mortality rates is unreliable because of small sample sizes at individual hospitals. Statistical power can be improved by combining mortality data from multiple operations. We sought to determine whether this approach would still be useful in understanding performance with individual procedures. Methods:We studied 11 high-risk operations performed in the national Medicare population (1996–1999). For each operation, we calculated 1) the risk-adjusted mortality rate for the procedure and 2) the mortality rate with up to 10 other operations combined (“other” mortality). To test for an association between these mortality rates, we calculated the correlation coefficient adjusting for random variation. We then collapsed hospitals into quintiles of other mortality and calculated procedure-specific mortality rates within each of these quintiles. Results:Mortality with specific operations was modestly correlated with other mortality: coefficients ranged from 0.14 for pneumonectomy to 0.35 for esophagectomy. Despite small to moderate correlations, other mortality was a good predictor of procedure-specific mortality for 10 of the 11 operations. Pancreatic resection had the strongest relationship, with procedure-specific mortality rates at hospitals in the worst quintile of other mortality 3-fold higher than those in the best quintile (15.2% vs. 6.3%, P < 0.001). Pneumonectomy had the weakest relationship with no significant relationship between other mortality and procedure-specific mortality. Conclusions:Hospitals with low mortality rates for 1 operation tend to have lower mortality rates for other operations. These relationships suggest that different operations share important structures and processes of care related to performance. Future efforts aimed at predicting procedure-specific performance should consider incorporating data from other operations at that hospital.
Examining the Relationship between FindBugs Warnings and End User Ratings : A Case Study On 10 , 000 Android Apps

In the mobile app ecosystem, end user ratings of apps (a measure of end user perception) are extremely important to study as they are highly correlated with downloads and hence revenues. In this study we examine the relationship between the app ratings (and associated review-comments) from end users with the static analysis warnings (collected using FindBugs) from 10,000 free-todownload Android apps. In our case study, we find that specific categories of FindBugs warnings such as the ‘Bad Practice’, ‘Internationalization’, and ‘Performance’ categories are found significantly more in low-rated apps. We also find that there exists a correspondence between these three categories of warnings and the complaints in the review-comments of end users. These findings provide evidence that certain categories of warnings from FindBugs have a strong relationship with the rating of an app and hence are closely related to the user experience. Thus app developers can use static analysis tools such as FindBugs to potentially identify the culprit bugs behind the issues that users complain about, before they release the app.
Effects of captopril and enalapril on renal function in elderly patients with chronic heart failure.

OBJECTIVE: To compare the effects on renal function of captopril and enalapril in elderly patients with chronic heart failure. DESIGN: A multi-centre double-blind parallel-group comparison of the two angiotensin-converting enzyme (ACE) inhibitors, captopril (12.5 mg bid) and enalapril (2.5 mg bid). SUBJECTS: 80 elderly patients with chronic heart failure (41 in the captopril group, 39 in the enalapril group). MAIN OUTCOME MEASURES: The blood pressure and pulse rate response to the first dose of ACE inhibitor was assessed in all patients. Glomerular filtration rate (GFR) was measured radioisotopically by 99mTcDTPA or 51CrEDTA clearance after three and six months of each treatment. Subgroups were assessed for effective renal plasma flow (33 patients), exercise tolerance (25 patients) and by a symptom-oriented questionnaire (45 patients). RESULTS: No serious adverse effect on GFR was noticed. There was no significant difference between the two treatments in the mean baseline GFR or in changes from baseline at three and six months (captopril mean baseline GFR 49.6 ml min-1 1.76 m-2, enalapril 54.7 ml min-1 1.76 m-2; mean change (95% confidence interval) at three months captopril 12 ml min-1 (+3.0, +21.0), enalapril -2 ml min-1 (-13.0; +9.0); mean change at six months, captopril 3.7 ml min-1 (-6.7; +14.2), enalapril -6.0 ml min-1 (-21.0; +9.4). Significantly more patients given captopril had an improvement in GFR during the study period (26/31 compared with 20/31 enalapril-treated patients at three months, p = 0.0096, and 23/30 compared with 15/27 at six months, p = 0.021). There were no significant changes in effective renal plasma flow. Three patients treated with enalapril developed symptomatic hypotension within three days of starting treatment. Quality of life questionnaires revealed more gastrointestinal symptoms in the enalapril group (p = 0.039). CONCLUSIONS: Captopril seems marginally preferable to enalapril in the treatment of chronic heart failure in elderly patients.
From Women’s Quota to “Women’s Politics”: The Impact of Gender Quotas on Political Representations and Practices in the Pakistani National Parliament

Abstract In 2002, the Pakistani President Pervez Musharraf announced that 17% of the seats in the National Assembly and Senate would be reserved to women. Though quotas for women were not a new phenomenon in Pakistan, they had never reached this level. Moreover, after they had been dropped in 1988, the representation of women in the Pakistani parliament fell under 3%. Thus the entry of more than 80 women in Parliament (about 20% of all MPs) in 2002 was considered as a game changer in Pakistani politics, and Musharraf’s decision was generally praised by activists of the women’s movement. The article tries to evaluate how women construct new ways to do politics in their discourses and practices, and what place gender norms and representations occupy in this process. While recognizing women’s agency though quota regulations, it is also argued that a distinctive demarcation of ‘women’s politics’ can bring about constraints, contribute to women’s marginalization in the political field, and strengthen gender stereotypes. ----- Von Frauenquoten zu “Frauenpolitik”: Der Einfluss von Geschlechterquoten auf politische Reprasentation und Praxis im pakistanischen Parlament Zusammenfassung Im Jahr 2002 verkundete der damalige pakistanische Prasident Pervez Musharraf, dass 17% der Sitze in Nationalversammlung und Senat kunftig fur Frauen reserviert seien. Wenngleich eine Quotenregelung kein Novum fur das Land darstellte, war ihr Wert noch nie so hoch ausgefallen. Seit der Abschaffung der Quote im Jahr 1988 war die Reprasentation von Frauen im Parlament auf unter 3% gesunken. Als mit den Wahlen von 2002 dann 80 Frauen in die Nationalversammlung einzogen und ca. 20% aller Abgeordneten stellten, wurde die neue Regelung als bahnbrechend aufgefasst. Musharrafs Entscheidung erhielt viel Lob von Aktivistinnen der Frauenbewegung. Der Beitrag versucht zu beurteilen, wie Frauen sich in Diskurs und Praxis neue Wege geschaffen haben, um Politik zu machen. Wahrend die Agency von Frauen durch Quotenregeln durchaus anerkannt wird, lautet die Argumentation aber auch, dass eine gesonderte Demarkation von „Frauenpolitik“ Einschrankungen mit sich bringen, zur Marginalisierung von Frauen beitragen und Genderstereotype verstarken kann.
Dynamic organization of ATP and birefringent fibrils during free locomotion and galvanotaxis in the plasmodium of Physarum polycephalum

Directed migration by a cell is a good phenomenon for studying intracellular coordination. Dynamic organization of both ATP and birefringent fibrils throughout the cell was studied in the multinuclear ameboid cell of the Physarum plasmodium during free locomotion and galvanotaxis. In a directionally migrating plasmodium, waves of ATP as well as thickness oscillations propagated from just inside the advancing front to the rear, and ATP concentration was high at the front on the average. In a DC electric field, locomotion was inhibited more strongly, ATP concentration decreased more, and birefringent fibrils were formed more abundantly at the anodal than at the cathodal side. Inside the cell there were a few undulations in the distributions of ATP and birefringent fibrils. In short, birefringent fibrils become abundant where ATP concentration decreases. The possible mechanism of the coordination in the directed migration and the implications of the scaling law are discussed.
