Seniority Profiles in Unionized Workplaces: Do Unions Still Have the Edge?*

The focus of this study is to distinguish the different paths seniority earning profiles follow depending on whether the individual is employed in a workplace where trade unions and collective bargaining are present, or not. Within this framework, two propositions are set. In the union sector seniority should be an important determinant of wages, while in the non-union sector productivity, proxied by occupational experience, should have a key role on earning profiles. The empirical analysis verifies both propositions. Seniority earning profiles appear to be steeper in the union sector, while occupational expertise is estimated to have a more significant role in non-union jobs.

Tropical North Atlantic ocean‐atmosphere interactions synchronize forest carbon losses from hurricanes and Amazon fires

We describe a climate mode synchronizing forest carbon losses from North and South America by analyzing time series of tropical North Atlantic sea surface temperatures (SSTs), landfall hurricanes and tropical storms, and Amazon fires during 1995–2013. Years with anomalously high tropical North Atlantic SSTs during March–June were often followed by a more active hurricane season and a larger number of satellite‐detected fires in the southern Amazon during June–November. The relationship between North Atlantic tropical cyclones and southern Amazon fires (r = 0.61, p < 0.003) was stronger than links between SSTs and either cyclones or fires alone, suggesting that fires and tropical cyclones were directly coupled to the same underlying atmospheric dynamics governing tropical moisture redistribution. These relationships help explain why seasonal outlook forecasts for hurricanes and Amazon fires both failed in 2013 and may enable the design of improved early warning systems for drought and fire in Amazon forests.
Some stochastic properties of conditionally dependent frailty models

The frailty approach is commonly used in reliability theory and survival analysis to model the dependence between lifetimes of individuals or components subject to common risk factors; according to this model the frailty (an unobservable random vector that describes environmental conditions) acts simultaneously on the hazard functions of the lifetimes. Some interesting conditions for stochastic comparisons between random vectors defined in accordance with these models have been described in the literature; in particular, comparisons between frailty models have been studied by assuming independence for the baseline survival functions and the corresponding environmental parameters. In this paper, a generalization of these models is developed, which assumes conditional dependence between the components of the random vector, and some conditions for stochastic comparisons are provided. Some examples of frailty models satisfying these conditions are also described.
Mixing processes in a tropopause folding observed by a network of ST radar and lidar

A campaign devoted to stratosphere-troposphere exchange mechanisms studies has been held on 4–5 March 1995, during a tropopause folding passage over western Europe. The observational network included 1 UHF and 3 VHF radar, 1 temperature lidar, and 1 ozone lidar, deployed in the south of France. The fold is associated with a strong quasi meridional jet stream running along the west side of an upper level trough forming a potential vorticity ( PV ) anomaly. During this campaign, the PV anomaly is advected east-wards without major deformations, with an average velocity of about 30 km per hour. Therefore, a frozen field hypothesis has been used in order to compare the results obtained in the different sites of the network. Under this hypothesis, the same structures associated with the anomaly are observed by each radar or lidar, at the same time relative to this anomaly. The fold is put into evidence by the ozone lidar of the network and by the VHF radars when computing the aspect ratio. The turbulent activity observed by the OHP VHF radar and by the high resolution UHF PROUST radar (30 m altitude resolution) is concentrated in the wind shear regions generated by the jet stream above and below its axis. In the lower level wind shear, turbulent layers are detected within the fold and across its anticyclonic boundary, thus allowing turbulent exchanges with the tropospheric air masses. A large area of aspect ratio greater than 3 is observed in the troposphere during more than ten hours after the passage of the fold by the VHF radars. This particular signature is tentatively analyzed as the progressive dilution of air masses of stratospheric origin extruded from the fold by the turbulent processes. In the upper level wind shears, turbulent layers parallel to the wind isotachs are observed, whose thickness is often smaller than 100 m and are separated by non turbulent regions. A good correlation is found between the spatio-temporal evolution of these turbulent structures observed by the PROUST radar, and the stability structures observed at the same relative time by the temperature lidar. In addition the same turbulent structures are observed to be parallel to the isophase lines of the wind fluctuations, observed at the same relative time by the Lannemezan radar. These characteristics are compatible with the presence of unstable inertia-gravity waves, generated by the jet stream while the turbulent layers could be the signature of their saturation processes.

A Survey on Protocols securing the Internet of Things: DTLS, IPSec and IEEE 802.11i

Until 2020 more than 20 billion devices will be connected to the Internet. The communication between these devices must be secured for privacy, security and safety reasons. Constrained environments, low power assumptions and rapidly changing networks introduce new problems for classical communication protocols. One solution to this problem is to adapt successful protocols as lightweight implementations to fit the requirements established in an IoT context. In this work, we discuss cryptographic protocols and their lightweight variants with focus on the applicability to the Internet of Things. We give recommendations on which protocol to use in which application area and examine the applicability of the discussed protocols in the automotive environment, a concrete use case of the Internet of Things.

PERSONALIZED MEDIA RECOMMENDATION ALGORITHM BASED ON SMART HOME

Consider the personalized recommendation problem of content-based recommendation technology (CB), a personalized media recommendation algorithm based on smart home (PMRSH) is proposed. Firstly, on the basis of smart home, context model is given. And according to user context, recommendation set R1 is got by content-based recommendation. Then, by adopting the Bayesian Decision Theory to evaluate media items matching the situation context, the final recommendation set R is got. The simulation illustrates the effectiveness of the algorithm.
ON THE MODIFIED FUTAKI INVARIANT OF COMPLETE INTERSECTIONS IN PROJECTIVE SPACES

Let $M$ be a Fano manifold. We call a Kähler metric ${\it\omega}\in c_{1}(M)$ a Kähler–Ricci soliton if it satisfies the equation $\text{Ric}({\it\omega})-{\it\omega}=L_{V}{\it\omega}$ for some holomorphic vector field $V$ on $M$. It is known that a necessary condition for the existence of Kähler–Ricci solitons is the vanishing of the modified Futaki invariant introduced by Tian and Zhu. In a recent work of Berman and Nyström, it was generalized for (possibly singular) Fano varieties, and the notion of algebrogeometric stability of the pair $(M,V)$ was introduced. In this paper, we propose a method of computing the modified Futaki invariant for Fano complete intersections in projective spaces.

This brief review, which is a mix of newly and previously published information summarizes the current knowledge about the mentioned diseases of a number of selected plant species. Emphasis is given on description of symptoms, taxonomic position of the associated phytoplasmas and changes induced by phytoplasmal infections in the composition of secondary metabolites of affected plants.
Title Modeling of Plume Downwash and Enhanced Diffusion near Buildings : Comparison to Wind Tunnel Observations for in Arctic Industrial Site

The winter-time arctic atmospheric boundary layer was investigated with micrometeorological and SF, tracer measurements collected in Prudhoe Bay, Alaska. The flat, snow-covered tundra surface at this site generates a very small (0.03 cm) surface roughness. The relatively warm maritime air mass originating over the nearby, partially frozen Beaufort Sea is cooled at the tundra surface resulting in strong (4 to 30 “C . (100 m)-‘) temperature inversions with light winds and a persistent weak (1 to 2” C. (100 m)-‘) surface inversion with wind speeds up to 17 m ss’. The absence of any diurnal atmospheric stability pattern during the study was due to the very limited solar insolation. Vertical profiles were measured with a multi-level mast from 1 to 17 m and with a Doppler acoustic sounder from 60 to 450 m. With high wind speeds, stable layers below 17 m and above 300 m were typically separated by a layer of neutral stability. Turbulence statistics and spectra calculated at a height of 33 m are similar to measurements reported for non-arctic, open terrain sites and indicate that the production of turbulence is primarily due to wind shear. The distribution of wind direction recorded at 1 Hz was frequently non-Gaussian for l-hr periods but was always Gaussian for 5-min periods. We also observed non-Gaussian hourly averaged crosswind concentration profiles and assume that they can be modeled by calculating sequential short-term concentrations, using the 5-min standard deviation of horizontal wind direction fluctuations (a@) to estimate a horizontal dispersion coefficient ((T”), and constructing hourly concentrations by averaging the short-term results. Non-Gaussian hourly crosswind distributions are not unique to the arctic and can be observed at most field sites. A weak correlation between horizontal (a,.) and vertical (a,,,) turbulence observed for both 1-hr and 5-min periods indicates that a single stability classification method is not sufficient to determine both vertical and horizontal dispersion at this site. An estimate of the vertical dispersion coefficient, oZ, could be based on a+ or a stability classification parameter which includes vertical thermal and wind shear effects (e.g., Monin-Obukhov length, L).

Verifying Credence Attributes in Livestock Production

Livestock producers can respond to increasing consumer demand for certain production process attributes by providing verifiable information on the practices used. Consumer willingness to pay data were used to inform producer decision-making regarding selection of verification entities for four key production process attributes in the production of pork chops and milk. The potential for informing farm-level decision-making with information about consumer demand for product and production process attributes exists beyond the two products assessed as example cases in this analysis.
The Study of Organizational Learning Influence on Organizational Silence

The aim of this research is to study the influence of organizational learning on organizational silence in Hamedan Maskan Bank. One of the most important barriers in reaching the goals and the programs of the organizations is the lack of information and knowledge and also existence of what researchers called as organizational silence which refers to being silent in expressing ideas and creative alternatives. Now days, organizational silence is popular and epidemic around the world, therefore; organizational management should find out the factors influencing on organizational silence and try to remove the negative elements and beside, try to improve the positive effects which lead to the increasing of job satisfaction and organizational motivation. The study is practical due to its aims and is descriptive due to its methodology. The statistical society included all 260 staffs of Hamedan Maskan Bank among whom the researcher selected 152 persons according to Krejcie and Morgan Table and random selection was used to do this. The hypotheses of the research were: (Main Hypothesis) There is a negative relationship between organizational learning and organizational silence; (1 st alternative) there is a negative relationship between knowledge learning and organizational silence; (2 nd alternative) there is negative relationship between employees’ information interpretation and organizational silence; and (3 rd alternative) there is a negative relationship between organizational memory and organizational silence. In order to collect the data needed, the researcher used Questionnaire of Vakula (2003) which is consisted of 23 questions, and Toy Questionnaire which is consisted of 12 questions. The validity and reliability for questionnaire was 0/83 which was tested through Alpha Coefficient, and then it was accepted. In order to evaluate the relationship between the variables, we used K-S test and also SPSS software (version 19). The results showed that there is a negative relationship between the organizational learning and organizational silence. It means that the lore we have
A combination of semantic and attribute-based access control model for virtual organizations

A Virtual Organization (VO) consists of some real organizations with common interests, which aims to provide inter organizational associations to reach some common goals by sharing their resources with each other. Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex environment with the huge number of users and resources, traditional access control models cannot satisfy VOs security requirements. Most of the current proposals are basically based on the attributes of users and resources. In this paper, we suggest using a combination of the semantic based access control (SBAC) model, and the attribute based access control (ABAC) model with the shared ontology of subjects' attributes in VOs. In this model, each participating organization makes its access control decisions according to an enhanced model of the ABAC model. However, access decision in the VO is made in more abstract level through an enhanced model of theSBACmodel. Using the ontology of users and resources in this model facilitates access control in large scale VOs with numerous organizations. By the combination ofSBACand ABAC, we attain their benefits and eliminate their shortcomings. In order to show the applicability of the proposed model, an access control system, based on the proposed model, has been implemented in Java using available APIs, including Sun's XACML API, Jena, Pellet, and Protege.

Methods for Finding Interesting Nodes in Weighted Graphs

With the increasing amount of graph-structured data available, finding interesting objects, i.e., nodes in graphs, becomes more and more important. In this thesis we focus on finding interesting nodes and sets of nodes in graphs or networks. We propose several definitions of node interestingness as well as different methods to find such nodes. Specifically, we propose to consider nodes as interesting based on their relevance and non-redundancy or representativeness w.r. t. the graph topology, as well as based on their characterisation for a class, such as a given node attribute value. Identifying nodes that are relevant, but non-redundant to each other is motivated by the need to get an overview of different pieces of information related to a set of given nodes. Finding representative nodes is of interest, e.g. when the user needs or wants to select a few nodes that abstract the large set of nodes. Discovering nodes characteristic for a class helps to understand the causes behind that class. Next, four methods are proposed to find a representative set of interesting nodes. The first one incrementally picks one interesting node after another. The second iteratively changes the set of nodes to improve its overall interestingness. The third method clusters nodes and picks a medoid node as a representative for each cluster. Finally, the fourth method contrasts diverse sets of nodes in order to select nodes characteristic for their class, even if the classes are not identical across the selected nodes. The first three
Corporate Governance in Insurance Companies

Corporate governance in all companies, including insurance companies, includes the rules, regulations and institutions that regulate the way in which the governance and control of these companies is performed and implement them in practice. The basic requirement of development and implementation of corporate governance is the improvement of all of the economic indicators, primarily the long-term sustainable development in the interests of the owners and all other stakeholders, including policyholders, creditors, employees, government and the wider community. The aim of the paper is to analyse the application of corporate governance in the insurance in the world and in Serbia. Since there is no generally accepted framework for standardisation of corporate governance, as it differs depending on the specifics of each individual insurance company, the subject of the research in the paper is a general framework of corporate governance applicable to all insurance companies with necessary calibration to the level of individual companies. In the paper we first point out the importance of the application of corporate governance in the insurance and specifics of the legal framework of corporate governance in insurance companies in Serbia and then analyse the quality of corporate governance, reporting on the implementation of corporate governance and international principles.
Jogjakarta THE OPTIMATION OF PRODUCTION ZEOLITE SYNTHESIS Y FROM RICE HUSK ASH

Rice husk is the milling byproduct of rice and is a major waste product of the agriculture industry. Amorphous silica, commonly referred to as rice husk ash, was extracted from rice husk by acid leaching, pyrolysis, and carbon-removing processes. On the other hand, the pure silica with a high specific surface area, high melting point and high porosity can be obtained from rice husks. These properties make the ash a valuable raw material for many industries. This paper is study of synthesized of zeolite Y from rice husk ash. Zeolite Y synthesis is used for petroleum industry as expensive catalyst. Rice husk was calcined at temperature 700 o C for two hours using furnace to produce pure silica . The composition of synthesized of zeolite Y from rice husk was 2.24 Na2O : Al2O3 : 8 SiO2 : 112 H2O. The gel solution was mixed at room temperature for 24 hours using autoclave. Then, the gel solution was heated with variable temperature and time crystallization. The product zeolite synthesis Y was filtered and washed with distilled water until pH lower than ten, than dried at oven. This product was analyzed with X-Ray Diffraction (XRD). From XRD analyze result indicated that from rice husk ash can produced zeolite synthesis Y which high structure and crystallization degree. The optimum condition for synthesized zeolite Y from rice husk ash was temperature 100 o C for 48 hours. Keyword: Optimization, Rice Husk Ash, Synthesized, Zeolite Y

The morphology of the Brewer–Dobson circulation and its response to climate change in CMIP5 simulations

This article analyses the annual mean vertical and latitudinal structure of the Brewer–Dobson circulation in the CMIP5 models. The strength of the tropical mass upwelling is found to increase at all altitudes throughout the stratosphere due to climate change. However, the width of the tropical upwelling region narrows below about 20 hPa, and widens above 20 hPa, suggesting different physical mechanisms may play a role in this change above and below 20 hPa. In the lower stratosphere, an equatorward shift in the stationary wave critical line allows waves to propagate further into the Tropics. However, in the upper stratosphere, where the behaviour is dominated by what happens during the winter, an increase in the extratropical zonal mean westerly jet leads to a reduced equatorward refraction of planetary waves. The seasonal cycle of the change in the Brewer–Dobson circulation is also considered, and differences are found in the latitudinal structure of the increased extratropical downwelling between the Northern and Southern Hemispheres in winter.
