Optimal control of labour potential of the region

Human resources as a basis for economic development of a country become apparent in the labour potential of the population. Thereby, active employment policy, job hunting stimulation, training, professional skills, acquisition of a new profession is needed. When developing the regional employment policy, the labour potential must be used to get the best of quantitative and qualitative changes in the workforce, as well as methods to ensure their effectiveness. Different social and economic processes in the region influence change of the regional labour potential. Economic and mathematical modeling of the labour potential allows solving control problems at the regional level. The research highlights the key social and economic processes in the region that influence changes of its labour potential. The differential equation was stated to describe these changes and represent together with the conditions that are given to solve it, a mathematical model of the dynamics of the labour potential. The optimal control task of the amount of unemployed people of working age is studied within this model. The proposed economic and mathematical model of the labour potential of the region is tested on statistical data of the economy of Stavropol region.

Supervising student projects using content management systems

This paper explains the concept of web content management systems (web CMS) and presents a CMS called Centura, developed at the Faculty of Electronic En- gineering in Nis. The way this solution can be used for supervising student projects is discussed in details. We also present the architecture of Centura, emphasizing the elements in the logical structure that can be used for adding new functionalities to the system, without changing the existing application architecture. Using this exten- sion points, we introduce new behavior for standard elements, adjusting them to meet special requirements of student project management.

A Study on Recommendation Systems in Location Based Social Networking

Smart devices in the hands of people are revolutionizing the social lifestyle of one's self. Everyone across the world are using smart devices linked to their social networking activities one such activity is to share location data by uploading the tagged media content like photos, videos. The data is of surroundings, events attended/attending and travel experiences. Users share their experiences at a given location through localization techniques. Using such data from social networks an attempt is made to analyse tagged media content to acquire information on user context, individual’s interests, tastes, behaviours and derive meaningful relationships amongst them are referred to as Location Based Social Networks (LBSNs). The resulting information can be used to market a product and to improve business, as well recommend a travel and plan an itinerary. This paper presents a comprehensive survey of recommended systems for LBSNs covering the concepts of LBSNs, terminologies of LBSN and various recommendation systems.
The High-Stakes Effects of "Low-Stakes" Testing: Performance Labels Matter to Vulnerable Students

for providing the data and for answering many questions about data collection procedures. Address correspondence to John Papay (john_papay@mail.harvard.edu). 2 ABSTRACT Under No Child Left Behind, students across the country take annual standardized tests to measure their progress towards state content standards. Although these test results are used to hold schools and districts accountable, the scores on most of the state-mandated tests have no official stakes attached for students. We extend the literature on responses to information by examining whether performance labels students receive on state-mandated tests affect their subsequent educational attainments. A model in which well informed teachers, parents, and students base their actions on the best information available would predict that performance labels would not matter, given that all of these groups have access to the fine-grained test scores on which the performance categories are based. Using a regression-discontinuity design, we test this " no effect of labels " hypothesis by comparing outcomes of students with essentially equal proficiency scoring near the cut score to determine whether being assigned a more positive label improves future outcomes. We find small but substantively important and persistent effects of earning a more positive label on the educational attainments of urban, low-income students. Furthermore, we find that these effects are concentrated among those students who do not plan to attend a four-year college after high school. For these students, simply being classified as " Advanced " rather than " Proficient " on the 10 th grade mathematics examination increases by 8 percentage points the probability that they graduate from high school on time and increases by nearly 15 percentage points the probability that they enroll in college. The advent of standards-based reform in American public education has increased dramatically the amount of information available about the mathematics and reading skills of American public school students. Under the No Child Left Behind Act of 2001, all states must test students annually in grades 3 through 8 and once in high school. One of the key features of such test-based accountability systems is that every student receives not only a test score but also a performance label (e.g., Failing, Proficient, Advanced) based on their performance. Because the label is assigned entirely based on the test score, in theory it provides no additional information above and beyond the test score itself. Thus, rational economic agents who use all available information should not respond to the …
Psychometric Properties of the Turkish Version of the Fertility Adjustment Scale (T-FAS)

Objective: Infertile women are confronted with many difficulties during the treatment process, which require significant psychological adjustments. The level of infertility adjustment is only evaluated by using the Fertility Adjustment Scale (FAS), which is originally developed with English speaking populations. The objective of this study was translated and test psychometric properties of the Turkish version of FAS (T-FAS). Material and Methods: This methodological study was conducted with 240 infertile women in the infertility center of a university hospital in Turkey. The validity of the T-FAS was investigated by using Content Validity Indexing and Confirmatory Factor Analysis. Also, Cronbach’s alpha coefficients for reliability were used. Results: The content validity of the T-FAS was good according to Content Validity Index score (0.89). A two-component structure was extracted from factor analysis. Cronbach’s alpha of 0.81 showed moderate reliability while the stuck into having children and acceptation of life without children’ subscales showed Cronbach’s alphas of 0.80 and 0.71, respectively. Conclusion: The results supported the content and construct validity and reliability of the T-FAS for use with measuring infertility adjustment in a population of Turkish women. Evaluating infertile women’ perception of adjustment with the T-FAS may be useful in clinical studies in Turkey. T-FAS can be used by health care professional as a counseling tool to help guide women.
Prediction of Secondary Structure of Citrus Viroids Reported from Southern Iran

Viroids are smallest, single-stranded, circular, highly structured plant pathogenic RNAs that do not code for any protein. Viroids belong to two families, the Avsunviroidae and the Pospiviroidae. Members of the Pospiviroidae family adopt a rod-like secondary structure. In this study the most stable secondary structures of citrus viroid variants that reported from Fars province were drawn. The most stable secondary structures of these viroid variants were a classical rod-like structure and adopted cruciform structure including various additional small hairpins. Comparison of secondary structures of these viroid variants with other viroid variants indicates their highly similarities in the rod-like structures, number of loops and free energies and its obvious to result these closest variants of the Pospiviroidae family. HSVdcit1 and CVd-III-1 differed from under study variants in the stability and number of secondary structure branches. Because of relationship between secondary structure and pathogenicity of viroids, it is supposed that these two variants possibly will have high risk for citrus cultivations.
Detailed insight into Arctic climatic variability during MIS 11c at Lake El'gygytgyn, NE Russia

Abstract. Here we present a detailed multi-proxy record of the climate and environmental evolution at Lake El'gygytgyn, Far East Russian Arctic during the period 430–395 ka covering the marine isotope stage (MIS) 12/11 transition and the thermal maximum of super interglacial MIS 11c. The MIS 12/11 transition at Lake El'gygytgyn is characterized by initial warming followed by a cold reversal implying similarities to the last deglaciation. The thermal maximum of MIS 11c is characterized by full and remarkably stable interglacial conditions with mean temperatures of the warmest month (MTWM) ranging between ca. 10–15 °C; annual precipitation (PANN) ranging between ca. 300–600 mm; strong in-lake productivity coinciding with dark coniferous forests in the catchment; annual disintegration of the lake ice cover; and full mixis of the water column. Such conditions persisted, according to our age model, for ca. 27 ± 8 kyr between ca. 425–398 ka. The Lake El'gygytgyn record closely resembles the climate pattern recorded in Lake Baikal (SE Siberia) sediments and Antarctic ice cores, implying interhemispheric climate connectivity during MIS 11c.
Integration and Cooperation in Public Hospitals

Hospital care is a joint production involving a wide range of services; ranging from medical services to support services to hotel services. This paper, focusing on the cooperation between these services, models the internal organization of public hospitals. The analysis is based on the property rights approach to organization (aka the Grossman-Hart-Moore model) and adopts it to the realities of public hospitals. Some institutional features from the Swedish hospital sector are presented to support the analysis, but the results are general. It is found that support services should be integrated into the medical specialities and that hotel services should be outsourced by the hospital. Moreover, it is found that cooperating medical specialities should be integrated, giving support to the use of multi-skilled teams suggested by the advocates of lean health care.
Screening of thermophilic neutral lipase-producing Pseudomonas sp. ZBC1 and improving its enzymatic activity

From oil-contaminated soil, three lipase-producing microorganisms were selected as good lipase producers using rhodamine B-olive oil plate agar and they were identified as from Pseudomonas, Burkholderia and Klebsiella genera by morphology, biochemical characterization and 16S rRNA gene sequencing. Among the three strains, Pseudomonas sp. ZBC1 was found to produce thermophilic neutral lipase which exhibited maximum activity at 80oC and pH 7.0. Plackett-Burman design (PB design) and response surface methodology (RSM) analysis showed that the optimum values of the most significant factors are MgSO4 (0.85 g/L), inoculum size (65.9 ml/L) and volume of medium (51.57 ml). Under the optimal conditions, lipase production by Pseudomonas sp. ZBC1 was enhanced by approximately 2.30 fold (from 8.50 to 19.50 U/ml). Keywords : Pseudomonas , lipase, thermophilic, response surface methodology African Journal of Biotechnology Vol. 12(9), pp. 949-957
Characterization of lactic acid bacteria isolated from artisanal Zlatar cheeses produced at two different geographical location

Eighty-one strains of lactic acid bacteria (LAB) were isolated from white semi-hard homemade cheese, designated Zlatar BGNV, which was taken from household settled on Northern side of mountain Zlatar. The Zlatar BGNV cheese was manufactured from raw cow's milk without addition of the starter culture. All isolates of LAB were characterized by phenotypic and genotypic tests. Identification of strains was done by the repetitive extragenic palindromic-polymerase chain reaction (rep-PCR) with (GTG)5 primer and 16S rDNA sequence analysis. The most present species in Zlatar BGNV cheese were Lactobacillus casei/paracasei (65.43%) and Enterococcus faecalis (29.63%). Two facultative heterofermentative rods were identified as Lactobacillus plantarum (2.47%), and two obligate hetrofermentative LAB isolates as Lactobacillus parabuchneri (2.47%). Among all 81 tested isolates, only eight enterococci were producers of antimicrobial compounds. Fourteen of 16 tested lactobacilli isolates showed medium to very good proteolytic activity. All 57 lactobacilli from the Zlatar BGNV cheese curdled milk very slowly or did not curdle milk at all. However, three isolates of enterococci, BGNV1-63, BGNV1-76 and BGNV1-80, showed very good activity in milk and curdled milk within 5 h. They showed very high proteolytic activity hydrolyzing completely αs1- and κ-casein after 3 h, and β-casein after 30 min of incubation. In addition, those three enterococcal isolates degraded gelatin. Comparing obtained results with those previously achieved in examination of LAB microflora in another Zlatar BGZLS cheese made also from raw cow's milk, it can be concluded that LAB microflora in the Zlatar BGNV cheese is less diverse.
Atmospheric Measurement Techniques Evaluating nighttime CALIOP 0 . 532 μ m aerosol optical depth and extinction coefficient retrievals

NASA Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) Version 3.01 5-km nighttime 0.532 μm aerosol optical depth (AOD) datasets from 2007 are screened, averaged and evaluated at 1 ◦ × 1 resolution versus corresponding/co-incident 0.550 μm AOD derived using the US Navy Aerosol Analysis and Prediction System (NAAPS), featuring two-dimensional variational assimilation of quality-assured NASA Moderate Resolution Imaging Spectroradiometer (MODIS) and Multi-angle Imaging Spectroradiometer (MISR) AOD. In the absence of sunlight, since passive radiometric AOD retrievals rely overwhelmingly on scattered radiances, the model represents one of the few practical global estimates available from which to attempt such a validation. Daytime comparisons, though, provide useful context. Regional-mean CALIOP vertical profiles of night/day 0.532 μm extinction coefficient are compared with 0.523/0.532 μm ground-based lidar measurements to investigate representativeness and diurnal variability. In this analysis, mean nighttime CALIOP AOD are mostly lower than daytime (0.121 vs. 0.126 for all aggregated data points, and 0.099 vs. 0.102 when averaged globally per normalised 1 × 1 bin), though the relationship is reversed over land and coastal regions when the data are averaged per normalised bin (0.134/0.108 vs. 0140/0.112, respectively). Offsets assessed within single bins alone approach ±20 %. CALIOP AOD, both day and night, are higher than NAAPS over land (0.137 vs. 0.124) and equal over water (0.082 vs. 0.083) when averaged globally per normalised bin. However, for all data points inclusive, NAAPS exceeds CALIOP over land, coast and ocean, both day and night. Again, differences assessed within single bins approach 50 % in extreme cases. Correlation between CALIOP and NAAPS AOD is comparable during both day and night. Higher correlation is found nearest the equator, both as a function of sample size and relative signal magnitudes inherent at these latitudes. Root mean square deviation between CALIOP and NAAPS varies between 0.1 and 0.3 globally during both day/night. Averaging of CALIOP along-track AOD data points within a single NAAPS grid bin improves correlation and RMSD, though day/night and land/ocean biases persist and are believed systematic. Vertical profiles of extinction coefficient derived in the Caribbean compare well with ground-based lidar observations, though potentially anomalous selection of a priori lidar ratios for CALIOP retrievals is likely inducing some discrepancies. Mean effective aerosol layer top heights are stable between day and night, indicating consistent layeridentification diurnally, which is noteworthy considering the potential limiting effects of ambient solar noise during day.

Realization of Polarization-Insensitive Optical Polymer Waveguide Devices

We review our studies on the realization of polarization-insensitive optical polymer waveguide devices based on the approach of using thermal control to balance the geometric and stress birefringence in the waveguides. We demonstrate the idea with ridge/rib waveguides, Bragg gratings, directional couplers, and long-period gratings. Polarization-dependent loss compensation is also highlighted.
Comparison of Radiocarbon Ages from Different Organic Fractions in Tropical Peat Cores: Insights from Kalimantan, Indonesia

Various organic fractions of an Indonesian tropical peat deposit were dated using radiocarbon accelerator mass spectrometry (AMS). Four different depth layers, deposited during the last 28,000 14C yr, were analyzed and the data compared to bulk sample analyses. The pollen extracts consistently produced the oldest dates. The bulk samples (<250 μm and <100 μm) often yielded the youngest dates. The age difference between the individual fractions depended on the layer depth and hence the true age of the sampled peats. The age discrepancy was highest (∼16,000 14C yr) in the oldest peat material. We interpret this to be a consequence of the input of organic matter over a long period of time, with peat oxidation and/or no peat accumulation during the last glacial maximum (LGM). The age discrepancies were smaller (between 10 and 900 14C yr) for the Holocene peat samples. It was concluded that the pollen extract fraction might be the most reliable fraction for dating tropical peat deposits that are covered by deeply rooting vegetation.
Assessment on Antioxidant Potential and Enzyme Activity of Some Economic Resource Plants

The antioxidant potential and enzyme activities in Salicornia herbacea, Corylopsis coreana, Erythronium japonicum, Phragmites communis, Momordica Charantia, Nelumbo nucifera, Salvia plebeia, Portulaca oleracea, Ficus carica, Citrus junos and Cornus officinalis were determined. Their antioxidant activities were measured using DPPH radical scavenging and nitrite scavenging activity. Enzyme activities in investigated plants were evaluated as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX). The DPPH scavenging rate from 100 to 2500 mgL-1 was the highest in the flower of Corylopsis coreana. However, it was not detected in most of the samples at concentration below 100 mgL-1. The nitrite scavenging activity according to each kind of resource plants was significantly higher in the stem of Corylopsis coreana and leaf of Nelumbo nucifera. The root extract of Erythronium japonicum had the highest SOD enzyme activity of 94.0% while leaf of Salvia plebeia showed the lowest SOD enzyme activity of 30.4%. The activity of CAT and APX showed higher values in the stem of Corylopsis coreana, root of Erythronium japonicum and root of Phragmites communis in comparison with other plants. The activity of POD showed significantly high values in stem of Corylopsis coreana, Momordica Charantia and pericarp of Citrus junos extracts. The antioxidant enzyme activities differ significantly in different plants. In conclusion, we showed that Corylopsis coreana, Erythronium japonicum Cornus officinalis, and Momordica Charantia had the potent biological activities. Therefore, these plant resources showing antioxidant activity could be good materials for development of source of functional healthy food.
An X-ray diffuse scattering study of domains

X-ray off-specular diffuse scattering is used to directly probe the statistical distribution of domains in monolayers of F(CF2)10(CH2)2OH adsorbed at the hexane-water interface. These domains appear very near a transition from a monolayer solid to gas phase. The domains have a nearly constant radius of ≈ 1.5 µm and a nearest-neighbor separation that varies from 2 to 8 µm with temperature. Evidence that the domains are of equilibrium size suggests that the domain line tension, λt ≈ 3 × 10 −11 N, can be determined.
Root Cause Approach to Prisoner Radicalisation

Prison radicalisation in Australia has become a key focal point for the subject literature on radicalisation. However, while attention has been directed at identifying and apprehending violent extremists, less consideration has been given to what could be done with these people when convicted. This paper applies the root cause model to prisoner radicalisation to investigate the environmental, social and individual influences that contribute to radicalisation in prisons. This examination took a holistic view of the prison radicalisation process that is based on causal factors rather than the traditional phase model approach. It is argued that this is an important step in gaining an understanding of the interplay of influences in the prison radicalisation process. It is posited that once such an understanding is gained, it is more likely that effective disruption of the radicalisation process can occur.
Social-network-based water supply network sectorization methodology using monte carlo simulation to predict economical and operational benefits

Water Supply Network (WSN) sectorization is a broadly known technique aimed at enhancing water supply management. In general, existing methodologies for sectorization of WSNs are limited to assessment of the impact of its implementation over reduction of background leakage, underestimating increased capacity to detect new leakage events and undermining appropriate investment substantiation. In this work, we raise this issue and put in place a methodology to optimize sectors' design. To this end, we carry out a novel combination of the Short Run Economic Leakage Level concept (SRELL- corresponding to leakage level that can occur in a WSN in a certain period of time and whose reparation would be more costly than the benefits that can be obtained). With a non-deterministic optimization method based on Genetic Algorithms (GAs) in combination with Monte Carlo simulation. As an example of application, methodology is implemented over a 246 km pipe-long WSN, reporting 72 397 $/year as net profit.
