Antecedents and consequences of positive emotions in the workplace

This paper examined the relationship of social relations, role characteristics; transformational leadership and group emotions with positive individual emotions, its consequences on job satisfaction, stress, work motivation, individual performance and the mediating effect of positive emotions on the relationship of antecedent and outcome variables. The data were collected from 406 respondents from six organisations across hierarchy. The results suggested that social relations, transformational leadership and group emotions significantly predicted positive emotions, but role conflict and role ambiguity negatively predicted positive emotions. Positive emotions significantly predicted job satisfaction, work motivation and individual performance, but negatively predicted stress. Positive emotions also mediated the relationship between antecedent and outcome variables. The study contributes to the literature by identifying the role of certain individual and group level factors in building positive emotions and its impact on employee performance, motivation and satisfaction. The implications of the study are discussed.
Do Privacy Controls Influence Content Generation and Sharing Patterns of Online Social Network Users ? A Natural Experiment

In the age of social media, online social networks (OSNs), such as Facebook, Twitter, or LinkedIn, are indispensable for the majority of Internet users. To some, OSNs are as essential to their lives as electricity. These platforms enable OSN users to share content including status updates, pictures videos, comments, tags, and messages, with other people. Although most OSNs have been frequently criticized by privacy groups for the lack of attention to and care for privacy of their users, these platforms have continued to make inroads to new user bases. Today, OSNs are one of the fastest growing and most visited sites on the Internet. Facebook, the largest OSN, has reached 1 billion active users in September 2012 (Fowler 2012).
HE 0515–4414: an unusual sub-damped Ly $\alpha$ system revisited

Aims. We examine the ionization, abundances, and differential dust depletion of metals, the kinematic structure, and the physical conditions in the molecular hydrogen-bearing sub-damped Ly α system toward HE 0515−4414. Methods. We used the STIS and VLT UVES spectrographs to obtain high-resolution recordings of the damped Ly α profile and numerous associated metal lines. Observed element abundances were corrected with respect to dust depletion effects. Results. The sub-damped Ly α absorber at redshift z = 1.15 is unusual in several aspects. The velocity interval of associated metal lines extends for 700 km s −1 . In addition, saturated H i absorption is detected in the blue damping wing of the NHi = 8 × 10 19 cm −2 main component. The column density ratios of associated Al ii ,A liii ,a nd Feii lines indicate that the absorbing material is ionized. Nineteen of a total of 31 detected metal line components are formed within peripheral H ii regions, while only 12 components are associated with the predominantly neutral main absorber. The bimodal velocity distribution of metal line components suggests two interacting absorbers. For the main absorber, the observed abundance ratios of refractory elements to Zn range from a Galactic warm disk [Si/Zn]g = −0.40 ± 0.06, [Fe/Zn]g = −1.10 ± 0.05 to halo-like and essentially undepleted patterns. The dust-corrected metal abundances indicate a nucleosynthetic odd-even effect and might imply an anomalous depletion of Si relative to Fe for two components, but otherwise they do correspond to solar ratios. The intrinsic average metallicity is almost solar [Fe/H]m = −0.08 ± 0.19, whereas the uncorrected average is [Zn/H]g = −0.38 ± 0.04. The ion abundances in the periphery conform to solar element composition. Conclusions. The detection of H ii, as well as the large variation in dust depletion for this sight line, raises the question whether in future studies of damped Ly α systems ionization and depletion effects have to be considered in more detail. Ionization effects, for instance, may mimic an enrichment of α elements. An empirical recipe for detecting H ii regions is provided.
A comparison of fusion techniques in mel-cepstral based speaker identification

Input level fusion and output level fusion methods are compared for fusing Mel-frequency Cepstral Coefficients with their corresponding delta coefficients. A 49 speaker subset of the King database is used under wideband and telephone conditions. The best input level fusion system is more computationally complex than the output level fusion system. Both input and output fusion systems were able to outperform the best purely MFCC based system for wideband data. For King telephone data, only the output level fusion based system was able to outperform the best purely MFCC based system. Further experiments using NIST’96 data under matched and mismatched conditions were also performed. Provided it was well tuned, we found that the output level fused system always outperformed the input level fused system under all experimental conditions.
Broadband calibration of marine seismic sources used for academic research in the Southern Ocean: A case study with R/V Polarstern's airguns and airgun arrays

1. At earlier meetings of the Committee for environmental protection there has been discussion of the problems associated with identifying the “footprint” of acoustic sources when in use in the Southern Ocean. Whilst there have been studies on research vessels elsewhere in the world no such data appeared to exist for research vessels operating within the CCAMLR or Treaty Area. 2. Earlier papers from SCAR have urged that Parties interested in developing a deeper understanding of the possible interactions between marine mammals and acoustic systems should undertake targeted research in order to provide the relevant data on which management proposals could be based. 3. The Alfred Wegener Institute undertook a characterisation of Polarstern with a characteristic air gun array, using a calibration system established in Norway. 4. This paper was presented as a draft at the Cadiz Workshop on marine acoustics and is submitted here as an example of the research that SCAR has suggested is needed. It will be submitted for publication to a scientific journal this year.
Heat Shock Proteins and Regulatory T Cells

Heat shock proteins (HSPs) are important molecules required for ideal protein function. Extensive research on the functional properties of HSPs indicates that HSPs may be implicated in a wide range of physiological functions including immune function. In the immune system, HSPs are involved in cell proliferation, differentiation, cytokine release, and apoptosis. Therefore, the ability of the immune system, in particular immune cells, to function optimally and in unison with other physiological systems is in part dependent on signaling transduction processes, including bidirectional communication with HSPs. Regulatory T cells (Tregs) are important T cells with suppressive functions and impairments in their function have been associated with a number of autoimmune disorders. The purpose of this paper is to examine the relationship between HSPs and Tregs. The interrelationship between cells and proteins may be important in cellular functions necessary for cell survival and expansion during diseased state.
2013 7th International Conference on Pervasive Computing Technologies for Healthcare and Workshops Design Strategies for Youth-focused Pervasive Social Health Games

Adolescent obesity is an increasing challenge, and pervasive social health games hold much promise for promoting sustained healthy behaviors. Researchers and designers of these systems have many potential theories and existing best practices at their disposal. Our study, grounded in participatory design, shows which ones matter-both for pervasive social health games and within the cultural context of a community we studied over the course of three years. We worked with 112 US middle school students fr om a lower-income community in a series of participatory design exercises fo cused on social rewards for everyday physical activity. In our analysis, we discuss design implications in fo ur key areas: social presence, gender effects, incentives and competition. We show how these themes manifested in students' designs and why they were particularly important to our participants. We then use our findings to suggest design strategies for youth-focused pervasive social health games.
Per-tone equalization for single carrier block transmission with cyclic prefix

This paper proposes per-tone equalization methods for single carrier block transmission with cyclic prefix (SC-CP). Minimum mean-square-error (MMSE) based optimum weights of the per-tone equalizers are derived for SISO (single-input single-output), SIMO (single-input multiple-output), and MIMO (multiple-input multiple-output) SC-CP systems. The proposed equalizers have multiple taps for each tone, therefore, they can achieve good performance even when the length of the guard interval (GI) is shorter than channel order. Moreover, by employing sliding discrete Fourier transform (DFT), the proposed equalizers can be efficiently implemented. Computer simulation results show that the proposed equalizers can significantly improve the bit error rate (BER) performance of the SISO, SIMO, and MIMO SC-CP systems with the insufficient GI.
Justice in urban climate change adaptation: Criteria and application to Delhi

Cities around the world are increasingly developing plans to adapt to the consequences of climate change. These plans will have important consequences for urban populations because they are likely to reshape and reconfigure urban infrastructures, services, and decision making processes. It is critical that these adaptation plans are developed in a way that is just. Criteria was developed that can be used to assess justice in adaptation so that the processes, priorities, and impacts address the needs of the most vulnerable urban populations. Further, mechanisms are outlined that have been proposed as responsible for producing urban injustice. The justice criteria are applied to the case of adaptation planning in Delhi and the extent to which poor and informal populations are included and affected by this planning. The analysis shows that adaptation planning in Delhi does not meet the justice criteria in part because of a lack of capacity and the political economy of poverty in the city. The criteria for justice and mechanisms of injustice offer an important step toward developing a greater understanding of not only whether city-level adaptation planning is just, but also why it is or is not.

Bio-Inspired Routing Protocol for Vehicular Ad Hoc Networks

Vehicular ad hoc networks are highly mobile wireless networks that are designed to provide vehicle safety, monitor the traffic etc. In VANET mobility of vehicles cause the communication links between the vehicles to frequently be broken. So in order to improve road safety by providing timely and accurate information to drivers various routing protocols have been implemented. We present Bio-inspired routing protocol for VANET. It is based on continuous learning paradigm in order to take consideration of dynamic environmental changes. Hybrid protocol is based on urban as well as rural scenarios which gives road safety services by transmitting packets with minimum delay and high packet delivery ratio.
Learning boolean functions safe from local minima with aGeneralized

Nous pr esentons un nouveau r eseau de neurones, le Cliper, fond e sur une g en eralisation du Perceptron. Il permet de mod eliser des interactions entre un ensemble quelconque de neurones par des unit es de calcul appel ees des cliques. Le Cliper est capable de s eparer tout ensemble de patterns. La r egle d'apprentissage pour le Cliper, KLR, constitue notre principale contribution. Elle est bas ee sur une fonction d'erreur strictement convexe. Ainsi, elle apprend asympto-tiquement tous les ensembles s eparables de patterns, et d etecte la non s eparabilit e d'une partie importante des ensembles non s eparables. Les simulations faites pour les Clipers a cliques a etats binaires connrment les r esultats th eoriques, et mettent en valeur un excellent taux de g en eralisation. Abstract We present a new neural network, the CLiper, that rely on a generalization of the Perceptron. It allows to model interactions between any set of neurons through computing units named cliques. The Cliper is able to separate any learning set. Our main contribution is concerned with KLR, a learning rule for the Cliper. It is based on a strictly convex error function. So, it asymptotically learns all separable set of patterns, and detects the non separability of an important class of non separable sets. The simulations made for the Clipers with binary state cliques connrm theoretical results, and point out a excellent generalization rate.
TR-MABE: White-box traceable and revocable multi-authority attribute-based encryption and its applications to multi-level privacy-preserving e-healthcare cloud computing systems

Cloud-assisted e-healthcare systems significantly facilitate the patients to outsource their personal health information (PHI) for medical treatment of high quality and efficiency. Unfortunately, a series of unaddressed security and privacy issues dramatically impede its practicability and popularity. In e-healthcare systems, it is expected that only the primary physicians responsible for the patients treatment can not only access the PHI content but verify the real identity of the patient. Secondary physicians participating in medical consultation and/or research tasks, however, are only permitted to view or use the content of the protected PHI, while unauthorized entities cannot obtain anything. Existing work mainly focuses on patients conditional identity privacy by exploiting group signatures, which are very computationally costly. In this paper, we propose a white-box traceable and revocable multi-authority attribute-based encryption named TR-MABE to efficiently achieve multilevel privacy preservation without introducing additional special signatures. It can efficiently prevent secondary physicians from knowing the patients identity. Also, it can efficiently track the physicians who leak secret keys used to protect patients identity and PHI. Finally, formal security proof and extensive simulations demonstrate the effectiveness and practicability of our proposed TR-MABE in e-healthcare cloud computing systems.
Manifolds for training set selection through outlier detection

The effect of the training set on supervised classifier performance has always been overlooked. This paper provides a new approach for training set cleaning based on the concept of outlier detection to help build sound class models during the training of supervised classifiers. Outliers in a training set result in classifier performance deterioration and slow convergence. For training set cleaning, the proposed technique transforms non-linear relationships between high dimensional patterns into a simple geometric relationship. The Isometric pattern Mapping (ISOMAP) is used to embed the high dimensional training set patterns to a low-dimensional manifold. The dispersion of mapped points will be used to locate the outliers and measure their outlyingness. Several experiments on real data sets show the promising performance of the proposed technique.
Earnings Timeliness , Earnings Conservatism and Board Independence : Study based on Finnish listed Firms

The objective of this study is to examine the link between the board independence and earnings quality, proxied by earnings timeliness and earnings conservatism in Finnish listed companies. Earnings conservatism (conditional conservatism) provides significant benefits for the users of financial information. However, a firm’s governance structures may be important in determining earnings quality. Boards with more independent directors have a propensity for greater monitoring and are therefore expected to insist on greater earnings quality, as reflected in more timely recognition of bad news in earnings. In accordance with the Finnish Governance Code the concept of board members independence is carried out. With hand collected, high quality Finnish data during the period 2003-2005, research questions could be stated and analyzed.
Elevated Rates of Diabetes in Pacific Islanders and Asian Subgroups

OBJECTIVE We estimated the prevalence and incidence of diabetes among specific subgroups of Asians and Pacific Islanders (APIs) in a multiethnic U.S. population with uniform access to care. RESEARCH DESIGN AND METHODS This prospective cohort analysis included 2,123,548 adult members of Kaiser Permanente Northern California, including 1,704,363 with known race/ethnicity (white, 56.9%; Latino, 14.9%; African American, 8.0%; Filipino, 4.9%; Chinese, 4.0%; multiracial, 2.8%; Japanese, 0.9%; Native American, 0.6%; Pacific Islander, 0.5%; South Asian, 0.4%; and Southeast Asian, Korean, and Vietnamese, 0.1% each). We calculated age-standardized (to the 2010 U.S. population) and sex-adjusted diabetes prevalence at baseline and incidence (during the 2010 calendar year). Poisson models were used to estimate relative risks. RESULTS There were 210,632 subjects with prevalent diabetes as of 1 January 2010 and 15,357 incident cases of diabetes identified during 2010. The crude diabetes prevalence was 9.9% and the incidence was 8.0 cases per 1,000 person-years and, after standardizing by age and sex to the 2010 U.S. Census, 8.9% and 7.7 cases per 1,000 person-years. There was considerable variation among the seven largest API subgroups. Pacific Islanders, South Asians, and Filipinos had the highest prevalence (18.3, 15.9, and 16.1%, respectively) and the highest incidence (19.9, 17.2, and 14.7 cases per 1,000 person-years, respectively) of diabetes among all racial/ethnic groups, including minorities traditionally considered high risk (e.g., African Americans, Latinos, and Native Americans). CONCLUSIONS High rates of diabetes among Pacific Islanders, South Asians, and Filipinos are obscured by much lower rates among the large population of Chinese and several smaller Asian subgroups.
Dominant role by vertical wind shear in regulating aerosol effects on deep convective clouds

[1] Aerosol-cloud interaction is recognized as one of the key factors influencing cloud properties and precipitation regimes across local, regional, and global scales and remains one of the largest uncertainties in understanding and projecting future climate changes. Deep convective clouds (DCCs) play a crucial role in the general circulation, energy balance, and hydrological cycle of our climate system. The complex aerosol-DCC interactions continue to be puzzling as more ‘‘aerosol effects’’ unfold, and systematic assessment of such effects is lacking. Here we systematically assess the aerosol effects on isolated DCCs based on cloud-resolving model simulations with spectral bin cloud microphysics. We find a dominant role of vertical wind shear in regulating aerosol effects on isolated DCCs, i.e., vertical wind shear qualitatively determines whether aerosols suppress or enhance convective strength. Increasing aerosols always suppresses convection under strong wind shear and invigorates convection under weak wind shear until this effect saturates at an optimal aerosol loading. We also found that the decreasing rate of convective strength is greater in the humid air than that in the dry air when wind shear is strong. Our findings may resolve some of the seemingly contradictory results among past studies by considering the dominant effect of wind shear. Our results can provide the insights to better parameterize aerosol effects on convection by adding the factor of wind shear to the entrainment term, which could reduce uncertainties associated with aerosol effects on climate forcing.
Novice programmers' faults & failures in GOAL programs: Empirical observations and lessons

Copyright © 2014, International Foundation for Autonomous Agents and Multiagent Systems (www.ifaamas.org). All rights reserved. What are the types of mistakes ("faults") that novice GOAL programmers make, and how do they manifest as failures? This question is important since it has significant implications to the ongoing design of GOAL, and other agent-oriented programming languages; to the ongoing development of tools that support GOAL programmers; and to how we teach agent-oriented programming. In this paper we develop taxonomies for faults and for failures. We then classify the faults and failures that occur in a collection of programs by novice GOAL programmers. This provides empirical data which we use to make recommendations regarding the GOAL language, its support tools, and how it is taught.
Power Guru : Implementing Smart Power Management on the Android Platform

Improving battery life in mobile devices has become a very important area of research. Hardware components like the CPU, screens and radios has evolved quickly while battery technology has lacked the same progression. Our goal is to implement a smart power management system for the Android OS that makes multi-tasking more battery friendly. We do this by looking at the currently running applications and giving the user suggestions on which applications to kill in order to optimize the battery life of the device.
The Evolution of Obscuration in Active Galactic Nuclei

In order to study the evolution of the relative fraction of obscured active galactic nuclei (AGNs), we constructed the largest sample to date of AGNs selected in hard X-rays. The full sample contains 2341 X-ray-selected AGNs, roughly 4 times the largest previous samples studied in this connection. Of these, 1229 (53%) have optical counterparts for which redshifts are available; these span the redshift range z = 0-4. The observed fraction of obscured AGNs declines only slightly with redshift. Correcting for selection bias, we find that the intrinsic fraction of obscured AGNs must actually increase with redshift, as (1 + z)α, with α ≃ 0.4 ± 0.1. This evolution is consistent with the integrated X-ray background, which provides the strongest constraints at relatively low redshift, z ~ 1. Summing over all AGNs, we estimate the bolometric AGN light to be 3.8 nW m-2 sr-1, or ≲8% of the total extragalactic light. Together with the observed black hole mass density in the local universe, this implies an accretion efficiency of η ~ 0.1-0.2, consistent with the values typically assumed.
