Restructuring of Ural Enterprises and Changes in the Internal Labor Market: A Sociological Perspective

The internal labor market is a field where the employer and the employees interact within an organization, this field being similar in its functions to the ordinary external labor market, that is, it determines the cost of manpower, and the staff movements within the enterprise, which include both horizontal and vertical mobility. The processes analyzed by economists within the framework of the concept of the internal labor market are studied in sociology as processes of intra-organizational mobility: its factors, trajectories, and the ascent opportunities of its staff.

A simple subgroup decomposable measure of upward and downward income mobility

We propose a subgroup decomposable class of income mobility measures with good axiomatic properties by adapting the concept of “individual income gap between two moments in time” to a framework that is traditionally used in the measurement of poverty and deprivation. This framework is explicit in incorporating the necessary judgements about how to aggregate individual income gaps by making use of the indices with best normative properties within the poverty literature. This strategy allows us to provide intuitive and simple measures of downward (and upward) mobility that consider incidence, intensity and inequality of income gaps and are easy to comprehend and communicate to policy makers. Moreover, these measures are consistent with a simple and intuitive graphical device. As an empirical illustration of the use of this class of measures, we present an analysis of downward income mobility for different age groups in three EU countries using the European Union Survey of Income and Living Conditions (EUSILC) longitudinal data from 2004 up to 2015.Universidad de Málaga.

Measuring the Effect of Spell Recurrence on Poverty Dynamics

The analysis of poverty dynamics yields important insights about the expected effectiveness of alternative social policies on poverty reduction. This paper analyses the effect of spell recurrence on poverty dynamics taking into account multiple poverty and non-poverty spells. Using longitudinal data for Spain we obtain that the poverty exit and re-entry rates vary not only with personal or household characteristics but also with spell accumulation and with the duration of past spells. Results indicate that the effect of duration dependence is significant and turns out to be different by spell order. Our findings support progress towards incorporating full individual poverty trajectories more explicitly in estimating the likelihood of future poverty.poverty dynamics, multiple spells, recurrence

Approximations of the aggregated interference statistics for outage analysis in massive MTC

This paper presents several analytic closed-form approximations of the aggregated interference statistics within the framework of uplink massive machine-type-communications (mMTC), taking into account the random activity of the sensors. Given its discrete nature and the large number of devices involved, a continuous approximation based on the Gram–Charlier series expansion of a truncated Gaussian kernel is proposed. We use this approximation to derive an analytic closed-form expression for the outage probability, corresponding to the event of the signal-to-interference-and-noise ratio being below a detection threshold. This metric is useful since it can be used for evaluating the performance of mMTC systems. We analyze, as an illustrative application of the previous approximation, a scenario with several multi-antenna collector nodes, each equipped with a set of predefined spatial beams. We consider two setups, namely single- and multiple-resource, in reference to the number of resources that are allocated to each beam. A graph-based approach that minimizes the average outage probability, and that is based on the statistics approximation, is used as allocation strategy. Finally, we describe an access protocol where the resource identifiers are broadcast (distributed) through the beams. Numerical simulations prove the accuracy of the approximations and the benefits of the allocation strategy.Peer ReviewedPostprint (published version

Pengaruh Emotional Quotient Dan Spiritual Quotient Terhadap Business Performance; Studi Pada Usaha Pempek Di Palembang

This study aimed to examine the effect of emotional quotient and spiritual quotient on business performance at pempek shop in the city of Palembang. The sample used in thus study were of 30 pempek shop in the city of Palembang by purposive sampling method. Hypothesis testing using Multiple Linear Regression Analysis using SPSS 22.0. The results of this test state that 1) Emotional quotient give positive impact on the business performance, 2) Spiritual Quotient give positive impact on the business performance, 3) Emotional quotient and spiritual quotient together give positive impact on the business performance . Based on the adjusted R Square value of 0.143 which means that 14.3% variable business performance can be explained by the variable emotional quotient and spiritual quotient, while the remaining 85.7% is influenced by other variable not examined in this study

Successful isolation and cultivation of Cylindrospermopsis raciborskii strains isolated from finished drinking water samples

This work presents the successful establishment of Cylindrospermosis raciborskii cultures isolated from water samples collected at the exit point of Water Treatment Plant (WTP). An intense bloom dominated by filamentous cyanobacteria (Aphanizomenon spp., Planktothrix spp., Cylindrospermosis raciborskii, Anabaena spp.) occurred in the summer of 2015 in Roxo reservoir (south Portugal). Several cyanotoxins (microcystins, saxitoxins, cylindrospermopsin) were detected in raw and treated water, although at levels below the corresponding regulatory and/or guideline values. Nevertheless, this bloom caused intense unpleasant odour and taste in the water supplied to the populations and cyanobacterial cells (up to 1000 cells.mL-1) were detected in finished water samples collected at the exit point of WTP. Treated water samples collected at the WTP and at the city water deposit were inoculated in Z8 culture medium and cyanobacterial growth was followed by optical microscopy. After 30 days, cyanobacterial growth was observed showing resistance to the treatment processes and maintenance of reprodution capacity. Interestingly, morphometric and molecular analysis revealed the presence of C. raciborskii. Three isolates of this species were obtained and none were cylindrospermopsin- or microcystins-producers, as confirmed by Enzyme Linked Immunosorbent Assays (ELISA) and by amplification of genes (PS, PKS, mcyA-cd, mcyAB, mcyB) involved in those cyanotoxin synthesis. However, the ELISA for saxitoxins was positive for the 3 isolates and confirmation of this toxin production is in progress. To our knowledge, this is the first report on the establishment of successful cultures of C. raciborskii that survived to conventional water treatment processes.N/

Constraints on massive sterile plus active neutrino species in non minimal cosmologies

Cosmological measurements are affected by the energy density of both active and sterile massive neutrinos. We extend here a recent analysis of current cosmological data to non minimal cosmologies. Several possible scenarios are examined: a constant w \neq -1 dark energy equation of state, a non flat universe, a time varying dark energy component and coupled dark matter dark energy universes or modified gravity scenarios. When considering cosmological data only, (3+2) massive neutrino models with ~0.5 eV sterile species are allowed at 95% CL. This scenario has been shown to reconcile reactor, LSND and MiniBooNE positive signals with null results from other searches. Big Bang Nucleosynthesis bounds could compromise the viability of (3+2) models if the two sterile species are fully thermalized states at decoupling.Comment: 8 pages, 5 figure
