Information and Communications Technology and Inventory Management amongst Breweries in Nigeria

This study examined the effect of ICT on inventory management amongst breweries in Nigeria. Secondary data were sourced for this study. The population for the study comprises all brewery companies quoted on the Nigerian Stock Exchange. Purposive sampling technique was used in selecting the three leading brewery companies in Nigeria, namely the Nigerian Breweries Plc; Guinness Nigeria Plc; and International Breweries Plc that represent 75% of the breweries quoted in the Nigerian Stock Exchange factsbook. Secondary data on ICT/ software costs, inventories, sales turnover/revenue, and assets were sourced from years 2006 to 2015 Annual Reports and Statements of Accounts of the three selected breweries and the Nigeria Stock Exchange facts book. The data collected were analyzed using descriptive statistics ( tables, mean and standard deviation) and inferential statistics (Ordinary Least Square (OLS) method). The results also showed that ICT usage had no significant positive relationship on inventory management (t = 0.021, P > 0.01). The study concluded that ICT had no significant positive effect on inventory management in the Nigerian Brewery industry. It is recommended that brewery firms in Nigeria should deploy the right software for inventory management. The limitation of this research is what were used to measure the inventory management and Information and Communications Technology (ICT) as contrary results could be obtained if these variables are measured using other yardsticks. The improvement of the respondent required to see the other problem and another kind of business.
Biharmonic equation with Singular nonlinearity in R N ∗

There is a large literature concerning such singular problems (as well as the corresponding systems) for second order elliptic operators wherein questions of existence, uniqueness and multiplicity, regularity, asymptotic behaviour, symmetry, etc. have been investigated (see for instance [1], [3], [10], [11], [15], [21], [25], [27], [28]). Similar results for the quasilinear case have been obtained in [22] and [23]. We refer the reader to the two excellent surveys [19] and [26] for more details. There are very few results available which concern fourth order singular problems similar to (P ). In [20], the author studies the problem ∆2u = u, α < 1, but with Dirichlet boundary condition. Furthermore, the author assumes that the domain is a perturbation of the ball to ensure positivity of the associated Green’s function. Using the Schauder fixed point theorem
A systematic study of Galactic infrared bubbles along the Galactic plane with AKARI and Herschel. II. Spatial distributions of dust components around the bubbles

Galactic infrared (IR) bubbles, which can be seen as shell-like structures at mid-IR wavelengths, are known to possess massive stars within their shell boundaries. In our previous study (Hanaoka, 2019, PASJ, 71, 6), we expanded the research area to the whole Galactic plane ($0^{\circ } \le l \le 360^{\circ }$, $|b| \le 5^{\circ }$) and studied systematic differences in the shell morphology and the IR luminosity of the IR bubbles between inner and outer Galactic regions. In this study, utilizing high spatial-resolution data of AKARI and WISE in the mid-IR and Herschel in the far-IR, we investigate the spatial distributions of dust components around each IR bubble to discuss the relation between the star-formation activity and the dust properties of the IR bubbles. For the 247 IR bubbles studied in Hanaoka (2019, PASJ, 71, 6), 165 IR bubbles are investigated in this study, which have the Herschel data ($|b|\le 1^{\circ }$) and known distances. We created their spectral energy distributions on a pixel-by-pixel basis around each IR bubble, and decomposed them with a dust model consisting of polycyclic aromatic hydrocarbons (PAHs), hot dust, warm dust and cold dust. As a result, we find that the offsets of dust heating sources from the shell centers in inner Galactic regions are systematically larger than those in outer Galactic regions. Many of the broken bubbles in inner Galactic regions show large angles between the offset and the direction of the broken shell from the center. Moreover, the spatial variations of the PAH intensity and cold dust emissivity around the IR bubbles in inner Galactic regions are larger than those in outer Galactic regions. We discuss these results in light of the interstellar environments and the formation mechanism of the massive stars associated with the IR bubbles.
Production Risk, Farmer Welfare, and Bt Corn in the Philippines

We determine the production risk effects and welfare implications of single-trait Bt corn adoption in the Philippines. We use a stochastic production function estimation approach that allows for examining the skewness effects of Bt within a damage abatement specification. Our results indicate that Bt corn has a statistically significant yield increasing, risk-increasing (i.e., variance-increasing) and downside risk-reducing (i.e., skewness-increasing) effects. Based on risk premium, certainty equivalent, and loss probability welfare measures, Bt corn farmers in the Philippines are better-off (in absolute terms) relative to non-Bt farmers given Bt corn's dominant yield increasing effect and downside risk-reducing effect.
Involuntary Unemployment and Non-compensating Wage Differentials in an Experimental Labour Market

In this paper, the authors report the results of a series of efficiency wage experiments. Some of the key predictions of the efficiency wage hypothesis are qualitatively confirmed by the data: higher wages caused a reduction in shirking; firms offered contracts which exhibited positive job rents; firms offered systematically different wages and job rents which gave rise to noncompensating income differentials; and endogenous involuntary unemployment occurred.

L^1 metric geometry of big cohomology classes

Suppose $(X,\omega)$ is a compact K\"ahler manifold of dimension $n$, and $\theta$ is closed $(1,1)$-form representing a big cohomology class. We introduce a metric $d_1$ on the finite energy space $\mathcal{E}^1(X,\theta)$, making it a complete geodesic metric space. This construction is potentially more rigid compared to its analog from the K\"ahler case, as it only relies on pluripotential theory, with no reference to infinite dimensional $L^1$ Finsler geometry. Lastly, by adapting the results of Ross and Witt Nystr\"om to the big case, we show that one can construct geodesic rays in this space in a flexible manner.
THE OPTIMAL DESIGN OF A WIND TUNNEL MODEL STING SYSTEM BASED ON THE CFD METHOD

This paper aims to design a sting support system for a transonic wind tunnel test for a commercial wide-bodied aircraft, which includes a single sting and a blade support. Parameters of the sting support system have been analyzed and three key parameters are selected for optimization. A RANS solver has been developed to investigate the effects of key parameters on the sting support interference. Influences of four incidence angles and five locations of an expanding point on the single sting interference are studied, and also the effects of six vane leading edge sweep angles on the blade support interference are investigated. The optimal key parameters are determined, based on numerical results and structural rigidity. Structural intensity verification of the optimized support system has been performed under the estimated aerodynamic loading by commercial software. Results indicate that a 6° incidence angle and 03 expanding point are the optimal parameters for a single sting and a 50° leading edge sweep angle of the vane is optimal for blade support. The optimized sting system with sufficient safety factors is suitable for commercial wide-bodied aircraft wind tunnel tests, which implies the method in this paper can be used to optimize the sting support system of other vehicles.
Random Projection Forests

Ensemble methods---particularly those based on decision trees---have recently demonstrated superior performance in a variety of machine learning settings. We introduce a generalization of many existing decision tree methods called "Random Projection Forests" (RPF), which is any decision forest that uses (possibly data dependent and random) linear projections. Using this framework, we introduce a special case, called "Lumberjack", using very sparse random projections, that is, linear combinations of a small subset of features. Lumberjack obtains statistically significantly improved accuracy over Random Forests, Gradient Boosted Trees, and other approaches on a standard benchmark suites for classification with varying dimension, sample size, and number of classes. To illustrate how, why, and when Lumberjack outperforms other methods, we conduct extensive simulated experiments, in vectors, images, and nonlinear manifolds. Lumberjack typically yields improved performance over existing decision trees ensembles, while mitigating computational efficiency and scalability, and maintaining interpretability. Lumberjack can easily be incorporated into other ensemble methods such as boosting to obtain potentially similar gains.
Improved angular momentum evolution model for solar-like stars

Context. Understanding the origin and evolution of stellar angular momentum is one of the major challenges of stellar physics. Aims. We present new models for the rotational evolution of solar-like stars between 1 Myr and 10 Gyr with the aim of reproducing the distributions of rotational periods observed for star forming regions and young open clusters within this age range. Methods. The models include a new wind braking law based on recent numerical simulations of magnetized stellar winds and specific dynamo and mass-loss prescriptions are adopted to tie angular momentum loss to angular velocity. The models additionally assume constant angular velocity during the disk accretion phase and allow for decoupling between the radiative core and the convective envelope as soon as the former develops. Results. We have developed rotational evolution models for slow, median, and fast rotators with initial periods of 10, 7, and 1.4 d, respectively. The models reproduce reasonably well the rotational behavior of solar-type stars between 1 Myr and 4.5 Gyr, including pre-main sequence (PMS) to zero-age main sequence (ZAMS) spin up, prompt ZAMS spin down, and the early-main sequence (MS) convergence of surface rotation rates. We find the model parameters accounting for the slow and median rotators are very similar to each other, with a disk lifetime of 5 Myr and a core-envelope coupling timescale of 28−30 Myr. In contrast, fast rotators have both shorter disk lifetimes (2.5 Myr) and core-envelope coupling timescales (12 Myr). We show that a large amount of angular momentum is hidden in the radiative core for as long as 1 Gyr in these models and we discuss the implications for internal differential rotation and lithium depletion. We emphasize that these results are highly dependent on the adopted braking law. We also report a tentative correlation between the initial rotational period and disk lifetime, which suggests that protostellar spin down by massive disks in the embedded phase is at the origin of the initial dispersion of rotation rates in young stars. Conclusions. We conclude that this class of semi-empirical models successfully grasp the main trends of the rotational behavior of solar-type stars as they evolve and make specific predictions that may serve as a guide for further development.
The Slowly Varying Corona. I. Daily Differential Emission Measure Distributions Derived from EVE Spectra

Daily differential emission measure (DEM) distributions of the solar corona are derived from spectra obtained by the Extreme-ultraviolet Variability Experiment (EVE) over a 4 yr period starting in 2010 near solar minimum and continuing through the maximum of solar cycle 24. The DEMs are calculated using six strong emission features dominated by Fe lines of charge states viii, ix, xi, xii, xiv, and xvi that sample the nonflaring coronal temperature range 0.3–5 MK. A proxy for the non-Fe xviii emission in the wavelength band around the 93.9 Å line is demonstrated. There is little variability in the cool component of the corona (T < 1.3 MK) over the 4 yr, suggesting that the quiet-Sun corona does not respond strongly to the solar cycle, whereas the hotter component (T > 2.0 MK) varies by more than an order of magnitude. A discontinuity in the behavior of coronal diagnostics in 2011 February–March, around the time of the first X-class flare of cycle 24, suggests fundamentally different behavior in the corona under solar minimum and maximum conditions. This global state transition occurs over a period of several months. The DEMs are used to estimate the thermal energy of the visible solar corona (of order 1031 erg), its radiative energy loss rate ((2.5–8) erg s−1), and the corresponding energy turnover timescale (about an hour). The uncertainties associated with the DEMs and these derived values are mostly due to the coronal Fe abundance and density and the CHIANTI atomic line database.
The effect of decision frame and decision justification on risky choice

The purpose of this study was to examine the effect of decision frame, decision justification on risky choice. Subjects were 158 men and women. The results were as follows. (1) In the condition where no justification was requested, a framing effect (Tversky & Kahneman, 1981) was observed: Most of the subjects chose the riskless option when decision options were phrased positively in terms of gains, whereas most of the subjects chose the risky option when options were phrased negatively in terms of losses. (2) However, in the condition where justification was requested, the framing effect was not observed: Most of the subjects showed a consistent choice pattern. (3) The subjects in the justification-requested condition tended to choose risky option more often than the subjects in the no justification-requested condition did
Effect of topographic and temporal (maturity) gradients on the nutritive quality of semiarid herbaceous communities

Abstract Five slopes representative of the “dehesa”; grassland communities in the semi‐arid zones of Central‐Western Spain (province of Salamanca) were studied. Above‐ground biomass production was recorded from April to June and the NDF (neutral detergent fibre), ADF (acid detergent fibre), hemicellulose, cellulose, lignin, and digestibility were determined in the dry matter. Principal component analysis was applied to the data. The changes with time along the growth period show a parallel effect on the three positions of the slope, although the effect tended to be greater on the middle and upper zones. There were decreases in the levels of protein, cellular content, and digestibility, and an increase in cell wall components. The variability in nutritive characteristics induced by the phenology and time changes in the communities was reflected in the first factor of analysis, whereas the topographic gradient was related to the second component.
Developing laser scanning applications for mapping and monitoring single tree characteristics for the needs of urban forestry

Urban forests provide various ecosystem services. However, they also require fairly intensive management, which can be supported with up-to-date tree-level data. Until recently, the data have been collected using traditional field measurements. Laser scanning (LS) techniques provide efficient means for acquiring detailed three-dimensional (3D) data from the vegetation. The objective of this dissertation was to develop methods for mapping and monitoring urban forests at tree level. In substudy I, a method (MS-STI) utilizing multiple data sources was developed for extracting tree-level attributes. The method combined airborne laser scanning (ALS), field measurements, and tree locations. The field sample was generalized using the non-parametric nearest neighbor (NN) approach. The relative root mean square error (RMSE) of diameter at breast height (DBH) varied between 18.8–33.8%. The performance of MS-STI was assessed in substudy II by applying it to an existing tree register. 88.8% of the trees were successfully detected, and the relative RMSE of DBH for the most common diameter classes varied between 21.7–24.3%. In substudy III, downed trees were mapped from a recreational forest area by detecting changes in the canopy. 97.7% of the downed trees were detected and the commission error was 10%. Species group, DBH, and volume were estimated for all downed trees using ALS metrics and existing allometric models. For the DBH, the relative RMSE was 20.8% and 34.1% for conifers and deciduous trees respectively. Finally, in substudy IV, a method utilizing terrestrial laser scanning (TLS) and tree basic density was developed for estimating tree-level stem biomass for urban trees. The relative RMSE of the stem biomass estimates varied between 8.4–10.5%. The dissertation demonstrates the applicability of LS data in assessing tree-level attributes for urban forests. The methods developed show potential in providing the planning and management of urban forests with cost-efficient and up-to-date tree-level data.
IMPACT OF PSYCHOLOGICAL CHARACTERISTICS WITH THE MEDIATING EFFECT OF PSYCHOLOGICAL WELLBEING ON JOB PERFORMANCE : A CONCEPTUAL PAPER WITH REFERENCE TO SERVICE SECTOR RESEARCH PROPOSITIONS

The purpose of this conceptual paper is to find out the impact of psychological characteristics on job performance with the mediating effect of psychological wellbeing of customer service representatives. Relevant literature article have been perused and accordingly the proposition were proposed. It was found out from the literature that psychological characteristics such as emotional intelligence, psychological ownership and psychological capital play a vital role in the context of call center’s customer service representative’s job. In addition to this it was also found out that psychological wellbeing mediates the relationship between these personality characteristics and job performance. The research limitation is that conceptualized perspective of the variables mentioned have not been tested. The insight gain from this study will help in selection and recruitment strategies. The most prominent feature of the call center job is to interact with customers so while recruiting mangers can identify the factors that to what extent individuals are able to cope with proactive aspects of the call center job. This conceptual paper will contribute to the customer service literature by providing practical affirmation on the antecedents of psychological wellbeing.

Wood Discoloration and Decay in Grapevines with Esca Proper and Their Relationship with Foliar Symptoms

From two Italian vineyards affected with esca proper, vineyard A (Borghi, FC, Emilia-Romagna) and vineyard B (Controguerra, TE, Abruzzo), located in different wine-growing areas and with different cultivars, 165 vines were collected that had shown the leaf symptoms of esca proper in the years before. Each vine was inspected and the cubic volume of the main symptoms in the trunk was measured: discoloration, including the various forms of dark necrosis, and decay. In each vine of both vineyards the extent of wood deterioration was compared with the severity of the leaf symptoms recorded in the years before the vines were cut down. The existence of a correlation between discoloration and decay in the wood colonisation process was explored. No correlation was found between the severity of the wood deterioration and the severity of the leaf symptoms. The typical leaf symptoms were found also on vines that had only wood discoloration without any decay. There was no correlation between wood discoloration and decay in vineyard A in which the vine wood was more degraded, with a greater incidence of decay. In vineyard B, however, in which the incidence of decay was less, a correlation between decay and discoloration was potentially found.
Correlates Of Abuse Among Indian Adolescents In Rural Punjab

The present study comprising a sample of 310 adolescents from rural locations of Ludhiana district of Punjab state, was conducted to determine the correlates of abuse using a Personal Information Sheet, Self-concept Inventory and school records relating to academic achievement of the adolescents. Abuse among adolescents has been found to be associated with their birth-order, family income and family type. Significant differences are noted in the abuse among adolescents from joint and nuclear families. Mothers‟ education and occupation have also been found to be associated with abuse. A high degree of negative correlation has been observed between abuse and academic achievement of adolescents. Various preventive and remedial measures to check the menace of abuse among adolescents are suggested.
How students’ perceptions of teachers’ autonomy-supportive behaviours affect physical activity behaviour: an application of the trans-contextual model

Abstract The aim of this study was to assess a modified version of the trans-contextual model (Hagger, Chatzisarantis, Culverhouse, & Biddle, 2003) based on self-determination theory (Deci & Ryan, 1985) and the theory of planned behaviour (Ajzen, 1985). The modified version included two additional components: use of learning strategies and positive general feedback. It was hypothesized that students’ perceptions of how they use learning strategies taught by their physical education (PE) teachers and perceived positive general feedback would influence students’ intrinsic motivation, intentions, and physical activity behaviour in a leisure-time context through intrinsic motivation in PE. A structural equation model supported the hypotheses and demonstrated that the use of learning strategies and perceived positive general feedback in PE indirectly influenced intrinsic motivation in leisure time through the effect of intrinsic motivation in PE. There was a direct effect of perceived positive general feedback on physical activity behaviour as well as an indirect effect through the motivational sequence.
Sexual reproduction of Nausithoe aurea (Scyphozoa, Coronatae). Gametogenesis, egg release, embryonic development, and gastrulation*

SUMMARY: The structure of the ovaries and testes of Nausithoe aurea, reared in the laboratory, is described to update the knowledge of coronate scyphomedusae gametogenesis and early development. The testis is similar to those of other scyphozoans. The organization of the ovary agrees with the description for other coronates, with free oocytes in the mesoglea. The oocytes develop in a limited region of the gastrodermis, and a maturation gradient is observed from this point on. Egg release, embryonic development, and gastrulation mode of Nausithoe aurea are also described. Egg production was continuous for 55 days, and the output of released eggs oscillated without observed cue. Cleavage was holoblastic and adequal, but after the 8-cell stage, the cleavage became pseudospiral. Gastrulation occurred through multipolar ingression and began 24 hours after fertilization.
