Human resources relations

This new, dynamic, value-free universal paradigm supplies new concepts for the explanation of all HR/IR phenomena as products of the interaction of impersonal environmental forces with the direct and indirect stakeholders’ relevant characteristics, preferences, and expedients. It supplies new concepts for the inputs of the employee and the employer into their two-way employment interaction that brings about the productive and nonproductive utilization of the employee's human resources in an employment relationship. New concepts are also proposed for stakeholders’ decisions on action to defend and/or advance their preferences and/or expedients. The paradigm recognizes that such action always takes place in formal/informal influence channels leading to formal/informal decision arenas. It analyzes the possible outcomes of the interacting forces. The feedback of such outcomes to the stakeholders and their environments thus produces a continuous flow of HR/IR phenomena that remains constant unless the strength and/or composition of the forces change. Diagrams illustrate these new concepts and a practical example showing how their use improves research and theory.
Indoor Assistive Technology for Blinds using Visible Light Communication (VLC) and Machine Vision

: An advanced research in the field of mobile device users those who are physically challenged people like blinds, through guidance and support with their position identification is “Indoor Assistive Technology for Blinds using Visible Light Communication (VLC) and Machine Vision”. The technology used here are OpenCv and Android. It centers on automatic video capture, investigation and image processing the details of which are explained in the introduction. The system is useful mainly for blind people by assisting them to navigate from one place to another in Houses, Shopping Malls, Multiplex Theatres, Retail Stores, Departmental Stores, Factories and so on. A smart assisting approach dependent on man-made realization calculations is presented in an interior condition for relative situating for blind people, by guiding them and resolution construction via research and development procedure. In this system, relative location of mobile user (in this case, we refer to blind people) can be detected in the same mobile device so that it can guide them in a right direction. Moreover, in this project, we refer to the physically challenged people like blinds as android-based mobile users so as to offer a small contribution to the society.
Design of Circular Polarized Transmitter for RFID Tag

RFID stands for “radio-frequency identification”. It refers to the technology by which the digital data encoded in RFID tags or smart labels are captured by a reader via radio waves. RFID is uniform to barcoding in that data from a tag or label are captured by a device that stores the data in a database. However, RFID has many over systems which use barcode asset tracking software. The most notable is the RFID tag data that can be read outside the line-of-sight, whereas barcodes must be aligned with an optical scanner. RFID methods utilize radio waves to achieve this. At a basic stage, the RFID system is divided into three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags consist of an integrated circuit and an antenna, used to send data the RFID reader. After this, the reader transforms radio waves into a more usable data. Then, the data acquired from tags is transmitted via communication interface to the host pc, where the information gets accumulated in a database and later examined.
DATA "MISSING AT RANDOM" IN REAL ESTATE APPLICATIONS: A NEW SPATIAL DEPENDENCE APPROACH

There are many applied real estate studies that have data "missing at random". We develop a nonparametric geographic (or spatial) estimator that allows for average treatment e ect (ATE) heterogeneity across geographic space and addresses missing data problems. This approach uses propensity scores that re-weight by equating moments across treated (and untreated) sub-samples with the entire sample, allowing for separate tilting parameters in the treated and untreated samples, as in Graham et al. (2012). Our contribution is to add a second rebalancing, by down-weighting observations far from each target point. We call this a Geographic Inverse Probability Tilting (GIPT) estimator. GIPT allows for heterogeneous ATE estimates that vary by geographic location, and can utilize a large proportion of the sample in estimating the ATE at each target point. Small sample properties demonstrate that the ATE surface is smooth with GIPT. Our Monte Carlo simulations validate the strong small sample performance of GIPT. Among many possible real estate applications of GIPT, we demonstrate how a severe storm leading to an extended water-boil advisory, imposed much longer on sub-sections of Metro-Vancouver Canada (the treatment ), impacted individual commercial property prices (the ATEs) di erently.
A New Approach For Forecast Sales Growth In Automobile Industry

: in this study, a novel hybrid model is used for automobile sales forecasting based on the prediction results of time series forecasting. In order to improve the prediction or forecasting capability, the study integrates an Adaptive multiplicative triple exponential smoothing Holt-Winters (AHW) method and Backpropagation Neural Networks (BPNNs). The former method sets the weights required for Backpropagation in Neural Networks to improve the forecasting or prediction ability in the field of automobile sales industry. The proposed technique uses automobile sales data of recent years and prediction outcomes of time series to train the proposed forecasting model. The validation is carried out using real-world automobile sales data for both training and testing purposes. The result of proposed method outperforms the other neural network forecasting model in terms of automobile sales forecasting.
B chromosome variants in Prochilodus lineatus (Characiformes, Prochilodontidae) analyzed by microdissection and chromosome painting techniques

Abstract Several cytogenetic studies in Prochilodus lineatus (Valenciennes 1836) describe a striking system of supernumerary microchromosomes revealing the occurrence of three morphological types visualized as acrocentric, metacentric and submetacentric. The present study aimed to compare the DNA homology among the B chromosome variants, as well as the components of the standard complement using total B specific probes obtained by microdissection. This technique, which allows direct isolation of DNA from each B chromosome variant of interest, was applied to obtain the probes. Accordingly, cross hybridizations targeting all types were performed by using the fluorescence in situ hybridization technique. The results obtained revealed signals of hybridization on all kinds of B chromosomes, indicating homology among the variants. Moreover, markings on the standard A complement were observed using the B submetacentric chromosome specific probe. Based on these data, we can infer that B chromosome variants in P. lineatus have homologous regions, suggesting a common origin from an ancestral variant. Furthermore, it can be also hypothesized that the primitive supernumerary was probably originated from elements of the standard complement, since the B submetacentric morphotype shares sequences with the centromeric region of some chromosomes of the A complement.
Groundwater quality in parts of Ado-Ekiti Metropolis, South-Western Nigeria

Twenty-five (25) samples of groundwater sourced from boreholes and hand-dug wells were analyzed for twenty-three (23) physical and chemical parameters namely; Total hardness, Total dissolved solids (TDS), Conductivity, pH, Colour, Alkalinity, Turbidity, Nitrate (NO3), phosphate (PO3), Sulphate (SO4), Fluoride (Fl), Bicarbonate (HCO), Calcium (Ca), Potassium (K), Magnesium (Mg), Zinc (Zn), Sodium (Na), Iron (Fe), Manganese (Mn), Copper (Cu), Lead (Pb), Aluminum (Al) and Chloride (Cl) to determine their levels of portability and if the physico-chemical parameters fall within acceptable levels. Results show that most of the physical and chemical parameters are within acceptable limits as recommended by some regulatory organizations including the Nigeria Standard for Drinking Water Quality (NSDWQ) and World Health Organization (WHO). It was also observed that the order of abundance of the various cations was Ca > Mg > K > Na > Fe for well and borehole samples and SO4 Cl > NO3 > PO4 > HCO3 > Fl for the anions which generally agrees with the empirical pattern of mobility in secondary environment in natural water. The order of dominance of the trace elements was found to be Mn > Zn > Cu > Pb > Al and it is similar in both hand-dug well and borehole water samples. T-test results also showed that the differences in the concentrations of the measured parameters in both sample types (hand-dug wells and boreholes) are not significant. It was also observed that Mg-type water is predominant for cation concentration while Chloride and Sulphate type waters are predominant for the anion concentration for the two sample types. In addition, the Water Quality Index (WQI) values revealed that all the borehole water samples fall under the medium category while a few of the well samples fall under the Bad category and the rest under the Medium category. Conclusively, the groundwater in some parts of Ado-Ekiti can be considered as safe for domestic, agricultural and industrial usage although purification procedures should be carried out on some of the waters.
The Impact of Ambidextrous Leadership on Organizational Excellence: An Applied Study in Small and Medium Enterprises in Qatar

The study aimed to reveal the level of ambidextrous leadership and organizational excellence in small and medium enterprises in Qatar, and also to investigate the impact of ambidextrous leadership on organizational excellence in these companies. The study used analytical descriptive approach by designing a questionnaire that was composed of (42) items through six dimensions. The study sample included (456) employees working in SMEs in Qatar from low and medium managerial levels. Multiple and simple regression analyses were used for data analysis. The study results found that SMEs in Qatar have a high level of ambidextrous leadership and organizational excellence, and ambidextrous leadership competency has a significant impact on organizational excellence. Also, opening leader competency, closing leader competency, and flexible leader competency have a significant impact on organizational excellence. Based on these results, a set of recommendations were provided.
Efficiency optimization and design of analog circuits for a resonant DCDC converter for the LHC experiments upgrade

CERN (the European Organization for Nuclear Research) runs the largest particle physics laboratory in the world. Particle accelerators (in particular the Large Hadron Collider, LHC) and detectors are used at CERN to perform state-of-the-art experiments involving the collision of highly energetic particles. The High Luminosity LHC upgrade will allow performing more collisions per second, leading to a larger amount of data that can be collected by the detectors. This upgrade entails higher power consumption of the front-end circuits of the detectors and a minimization of the material used, so to optimize the physics performances of the experiments. Within this context, a specific power distribution system based on two steps of voltage conversion has been proposed, in order to properly supply the front-end circuits. The voltage conversion steps are performed by DCDC converters located close to the collision points, in a harsh environment characterized by high levels of radiations and high magnetic field (up to 4T). To face this challenge, radiation and magnetic field tolerant DCDC converters based on an Application Specific Integrated Circuit (ASIC) are in development, and several prototypes have been produced. A Resonant Switched Capacitor converter that targets the last step in the voltage conversion chain has been proposed, designed and prototyped. This converter steps down the voltage from 2.5V to 1.2V or 1V, providing a load current up to 3A. Two different output voltages are required so to properly supply, respectively, the analog and digital front-end circuits. The first part of this master thesis project has been devoted to the characterization and optimization of this prototype converter, in order to maximize its efficiency and minimize its mass and volume. A full electrical characterization of the converter has been performed together with an efficiency optimization, that has been achieved thanks to a careful choice of the most important passive discrete components. Basing on the results of the characterization campaign, the re-design of several analog blocks has been carried out in this work: in particular, an improved phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) have been developed. Furthermore, the control circuitry has been modified so to improve the converter performances and reliability.
GTF2IRD1 is a PRDM16-interacting transcription factor that represses TGF-beta-mediated inhibition of beige fat differentiation

Author(s): Mera, Linet | Advisor(s): Kajimura, Shingo | Abstract: The identification of beige fat within the last decade, its ability to burn energy in adult humans, and its great potential for therapeutic applications has motivated many to work towards understanding how beige fat is made. Although several proteins have been identified as important for beige fat differentiation, it is clear that the differences that distinguish beige fat from other types of fat cannot be explained by the presence of these proteins alone. Additional regulatory proteins, including transcription factors and their co-factor proteins, must be involved.I took advantage of two important developments in the field of fat differentiation to develop two high throughput approaches that identified new transcription factors involved in beige fat: (1) our ability to culture beige fat cells by differentiating white fat pre-adipocytes in the presence of Rosiglitazone and (2) the established role for PRDM16 as required for beige fat differentiation. In brief, I combined RNA-seq data from beige fat cells and proteomics data from Rosiglitazone-dependent PRDM16 protein complexes to identify a set of candidate transcription factors involved in beige fat differentiation. The most promising candidate among this pool of putative beige fat regulatory transcription factors was GTF2IRD1.I determined that GTF2IRD1 is a PRDM16-interacting transcription factor that is enriched in beige and brown fat cells. In vivo, GTF2IRD1 is enriched in brown adipose tissue and is increased in beige and brown fat in response to beta-3-adrenergic stimulus. In the presence of the potent PPARgamma agonist Rosiglitazone, GTF2IRD1 overexpression enhances and shRNA-mediated knockdown reduces beige fat differentiation. GTF2IRD1 represses TGF-beta-mediated inhibition of beige fat differentiation. In summary, my data strongly supports that GTF2IRD1 is an essential regulator of beige fat differentiation through interaction with PRDM16 and inhibition of TGF-beta-mediated repression of differentiation.
Human Papillomavirus: A Gender-Based Report on the Knowledge of College Students in Northern Greece

Title: This study was performed to evaluate the level of basic knowledge of students in Northern Greece regarding human papillomavirus matters, considering each gender’s aspect. Background: In every society it is fundamental that young adults should receive proper education for all Sexual Transmitted Diseases. This study aims on highlighting the necessity of aggressive campaigns, for informing students on HPV. Via a short survey, we performed a key evaluation of the knowledge of students to conclude on whether campaigns for informing students on HPV should be organized by the state. Methods and Findings: A questionnaire type of survey was undertaken to evaluate the level of basic knowledge of the sample regarding HPV. The questionnaire comprised of 11 questions. The first two questions were to determine specific characteristics of the sample; the third was about the participant’s belief of being well educated on HPV, while the rest of them were to evaluate their actual knowledge of the activity, pathogenesis and the national vaccination program against HPV. Five hundred sixty-one students of Northern Greece participated in the study (398 females and 161 males). Regarding their knowledge on HPV, most of the participants declared to be well informed with a rate of 76.1%. Indicatively, it appeared to be an independence regarding gender (p=0.44) about whether HPV can cause cancer to both sexes. As to vaccination, 50.7% of the participants, regardless gender, believed that HPV vaccine is effective on men (p=0.34). Conclusion: Students in Northern Greece seemed to be insufficiently informed about the general activity of HPV, pathogenicity, and vaccine’s effectiveness (p=0.00001). Similar surveys should be launched in the whole country for a proper evaluation to be obtained. The outcome of these studies could be rather beneficial in organizing educational campaigns for students of Greece and, if it is needed, to other countries as well.
Exploratory Study of 802.11ad Vehicular Links

IEEE 802.11ad leverages the large channel widths available in the 60 GHz mm-wave unlicensed spectrum to provide high throughput. Due to the high propagation loss at these frequencies, 802.11ad uses highly directional beamforming and constructive multipath to achieve indoor ranges of up to 50 m. It has been shown that 802.11ad links can be used outdoors for vehicular communications, but ranges tend be very short when few or no reflectors are present. While carrying out vehicular experiments with mobility, we occasionally observed communication ranges of up to ~30 m. We hypothesize that the cause lies in constructive reflections on the vehicles’ roofs, which function as ground planes. In this paper, we report preliminary results on the experiments and our efforts to quantify the roof’s ground plane effect using TP-Link Talon AD7200 802.11ad routers.
Characterization of Ajuga Plants Regenerated from Hairy Roots

20-Hydroxyecdysone (20-HE), one of the p ytoecdysteroids in practical possibilities for pest control1), chemotherapy2), and silk production3). In particular, al.3) have demon strated the use of 20-HE as a facilitator for the maturation of silkworms just before spinning cocoons. We have reported the establishment of a rapidly growing root clone producing a high amount of steroid in Ajuga reptans var. atropurpurea, one of the phytoecdysone-producing plants, by transfor mation with Agrobacterium rhizogenes4). Hairy roots have the ability to regenerate plants5). The plants regenerated from hairy roots also have some special characteristics, so-called 'hairy-root syndrome', such as active formation of adventitious root, high growth rate of roots in culture, reduced apical dominance in both stems and roots, altered leaf and flower morphology, plagiotropic root growth (i. e. with altered geotropism) and reduced pollen and seed production5). The dwarfism by shortened internodes is also recognized in regenerated plants. In this report, we demonstrate Ajuga plants regenerated from hairy roots, and their various properties such as growth, morphology of leaf, root mass, opine biosynthesis, and 20-HE productivity.
CHANGES IN INJURY-RELATED LOWER EXTREMITY BIOMECHANICS DUE TO A BASKETBALL-SPECIFIC FATIGUE PROTOCOL

The purpose of this study was to evaluate the effects of a basketball-specific fatigue protocol on lower extremity biomechanics and associated risk factors of ACL injury during a jump-stop task. The subjects consisted of twelve male collegiate basketball athletes. Participants performed six trials of jump-stop task. A basketball-specific fatigue protocol was performed and the biomechanical characteritics were conducted by paired t-tests with the significance level set at 0.05. The specific fatigue protocol caused a reduction of hip abduction and posterior ground reaction force. An increase of approach speed, knee flexion angle and vertical ground reaction force was also shown after fatigue. There was no difference on other variables. The basketball-specific fatigue protocol altered lower extremity biomechanics related to ACL injury risk during jump-stop tasks.

Comparative Assay of the Overhead of Efficient Version of CPDA Protocol to Original CPDA Protocol

— Data aggregation plays a vital role in Wireless sensor network which can be applied at aggregator nodes for effective bandwidth and energy. However in-network data aggregation presents a problem to the secrecy of sensor data because each individual sensor node data must be known to the aggregator before the aggregation process can be carried out. Providing efficient data aggregation while preserving data secrecy is a challenging problem in wireless sensor networks research. Therefore a number of Privacy-preserving data aggregation protocols have been proposed and one among them is CPDA [3] which is based on algebraic properties of polynomials. It suffers from vulnerable attack and is not energy efficient. A modified version of CPDA [2] has been proposed and it is more secure and energy efficient. In this paper, we present a brief comparative study of the overhead of modified version of CPDA to the existing privacy preserving CPDA version. Our study is based on two classifications of overheads in terms of communication and computation i) Overhead due to message transmission in the network ii) Computational overhead at the sensor node
Algorithmic Pricing and Competition: Empirical Evidence from the German Retail Gasoline Market

Economic theory provides ambiguous and conflicting predictions about the association between algorithmic pricing and competition. In this paper we provide the first empirical analysis of this relationship. We study Germany's retail gasoline market where algorithmic-pricing software became widely available by mid-2017, and for which we have access to comprehensive, high-frequency price data. Because adoption dates are unknown, we identify gas stations that adopt algorithmic-pricing software by testing for structural breaks in markers associated with algorithmic pricing. We nd a large number of station-level structural breaks around the suspected time of large-scale adoption. Using this information we investigate the impact of adoption on outcomes linked to competition. Because station-level adoption is endogenous, we use brand headquarter-level adoption decisions as instruments. Our IV results show that adoption increases margins by 9%, but only in non-monopoly markets. Restricting attention to duopoly markets, we find that market-level margins do not change when only one of the two stations adopts, but increase by 28% in markets where both do. These results suggest that AI adoption has a significant effect on competition.
