A Longitudinal Study of Age-Related Differences in Reactions to Psychological Contract Breach

The current paper investigated age-related differences in the relations of psychological contract breach with work outcomes over time. Based on socio-emotional selectivity theory, it was predicted that reactions to contract breach on job satisfaction and job performance would be stronger among younger workers than older workers. This two-wave panel study among 240 employees investigated interactions of age with three types of psychological contract breach (economic, socio-emotional, and developmental), in relation to changes in job satisfaction and job performance over time. Moderated structural equation modeling showed that negative affectivity partially mediated the relationships between contract breach and job satisfaction and job performance. Moreover, the analyses supported socio-emotional selectivity theory; older workers reacted less intensely to all three types of psychological contract breach towards job satisfaction and job performance, indicating a general decreased emotional responsiveness of .
Dispersive shallow water magnetohydrodynamics

Shallow water magnetohydrodynamics (SWMHD) is a recently proposed model for a thin layer of incompressible, electrically conducting fluid. The velocity and magnetic field are taken to be nearly two dimensional, with approximate magnetohydrostatic balance in the perpendicular direction, leading to a reduced two-dimensional model. The SWMHD equations have been found previously to admit unphysical cusp-like singularities in finite amplitude magnetogravity waves. This paper extends the Hamiltonian formulation of SWMHD to construct a dispersively regularized system, analogous to the Green–Naghdi equations of hydrodynamics, that supports smooth solitary waves and cnoidal wave trains, and shares the potential vorticity conservation properties of SWMHD.
On the spatial distributions of stars and gas in numerical simulations of molecular clouds

We compare the spatial distribution of stars which form in hydrodynamical simulations to the spatial distribution of the gas, using the $\mathcal{Q}$-parameter. The $\mathcal{Q}$-parameter enables a self-consistent comparison between the stars and gas because it uses a pixelated image of the gas as a distribution of points, in the same way that the stars (sink particles in the simulations) are a distribution of points. We find that, whereas the stars have a substructured, or hierarchical spatial distribution ($\mathcal{Q} \sim 0.4 - 0.7$), the gas is dominated by a smooth, concentrated component and typically has $\mathcal{Q} \sim 0.9$. We also find no statistical difference between the structure of the gas in simulations that form with feedback, and those that form without, despite these two processes producing visually different distributions. These results suggest that the link between the spatial distributions of gas, and the stars which form from them, is non-trivial.
Scale Effects in Oxygenation in the Breaker Zone of Coastal Structures

The significance of oxygen transfer across the air-water interface with its associated impact on water quality and environmental pollution control in coastal zones has become a matter of concern for coastal engineers. In the present paper experimental data on oxygen transfer obtained in the large scale facility of Delft Hydraulics have been presented. The obtained oxygen transfer coefficients have been compared to existing models for gas transfer under breaking and non breaking waves. Scale effects are found to be an important factor which needs to be considered when laboratory results are translated to field conditions.
Boundary Layer Receptivity: A Retrospect

Transition from laminar to turbulent flow in a boundary layer is of fundamental and practical importance, and as a result has been widely studied. Receptivity is the first stage of the transition process. The term receptivity was first used by Morkovin (1969) to describe the mechanism by which energy from the free stream enters and excites instability waves inside the boundary layer. Due to important role of receptivity theory in transition process of boundary layers, quite a few research works have been carried out in past few decades. This research review report tries to highlight the major research activities in this field of study that includes: the theory, different types of receptivity, its effect in three-dimensional boundary layers and receptivity at high speeds.
Replacement of Fishmeal With Blend of Canola Meal and Corn Gluten Meal, and an Attempt to Find Alternate Source of Milk Fat for Rohu (Labeo rohita)

Two laboratory feeding trials were conducted for 60 days using Labeo rohita, fingerling (3.7±1.9g and 6.9±1cm) to evaluate the possibility of replacing dietary fishmeal (FM) with a protein blend of canola meal and corn gluten meal (CGM), and to find alternate lipid sources for milk product without compromising the growth of fish. In experiment I, two experimental diets viz.; animal rich protein (ARP) as control diet and plant protein (PP), whereas, in experiment II, two experimental diets were; animal rich fat (ARF) as control diet and plant rich fat (PRF) were fed to L. rohita fingerlings, 20 in each group. A balance mixture of plant and animal protein and fat (MPF) was used as common diet for both experiments. The results revealed that there were no significant (P>0.05) differences among all feeding groups with respect to specific growth rate (SGR), weight gain (WG), feed conversion ratio (FCR) and protein efficiency (PE) in experiment I. Significant (P<0.01) difference were detected for percent fat, but protein content was non-significant. PP had high fat content, while MPF showed maximum protein content. In experiment II, significant differences were observed for SGR and WG. MPF showed better growth performance than other groups. Study indicated that partial or complete replacement of FM showed better results in terms of fish growth without compromising the growth rate of fish but complete replacement showed high deposition of fat in the body also. On other hand, a balance mixture of animal and plant lipid showed good outcomes in term of growth than complete replacement of milk lipid with rice polish and canola oil.
Evaluating the balance between vertical diffusive nitrate supply and nitrogen fixation with reference to nitrate uptake in the eastern subtropical North Atlantic Ocean

[1] The balance between N2 fixation and diffusive NO3− supply is a key determinant for assessing the importance of both processes for new production in subtropical waters. Here we report observations of integrated N2 fixation rates from the eastern subtropical North Atlantic Ocean with coincident estimates of diffusive NO3− supply. We find the average rate of N2 fixation is equivalent to 62% of the diffusive NO3− supply, though N2 fixation could exceed the diffusive flux at individual stations. Turbulent diffusivity measurements across the nitracline indicate a mean diffusivity of 0.077 cm2 s−1. If approximations for methodological underestimates in the dominant N2 fixation technique are considered, the magnitude of N2 fixation is shown to represent 100% of the NO3− flux on average, and can be almost threefold higher at individual stations. As the study site is characterized by low rates of N2 fixation compared to other sectors of the North Atlantic this confirms N2 fixation as a major source term across the subtropical North Atlantic. The seasonal context of our observations suggests environmental factors underlie the in situ variability in observed N2 fixation rates, and may well explain lower previous assessments of the importance of N2 fixation relative to diffusive NO3− supply in this region. The diffusive NO3− supply provides <20% of measurable NO3− uptake with the remainder supplied via other mechanisms, most notably nitrification. The mean integrated rate of N2 fixation equates to just 8% of the NO3− consumed on a daily basis by the phytoplankton community.
Surface Runoff along Two Agricultural Hillslopes with Contrasting Soils

The targeting of critical surface runoff-producing zones should account for the influence of subsurface soil characteristics. In this study we assessed the runoff response of contrasting colluvial and residual soils. The study was conducted along two hillslopes within a 39.5-ha mixed land use watershed In Pennsylvania. Six sites (four colluvial, two residual) were monitored for runoff, hydraulic head, water table depth, and soil water content. A total of 111 rainfall events were monitored during the periods of July to December 2000, April to December 2001, and April to December 2002. Two high-intensity (5-min peak > 8 cm h -1 ) events had return periods of 2.5 and 4 yr. The colluvial soils are somewhat poorly and moderately well drained with fragipans and high clay content (37-44%) argillic horizons (fine, mixed, semiactive, mesic Aquic Fragiudalfs); the residual soils are well drained with moderate clay content (24%) argillic horizons (fine-loamy, mixed, semiactive, mesic Typic Hapludults). Across all events, overall runoff yields averaged 2.4% from the four colluvial sites and 0.01% from the two residual sites. The two colluvial sites with the greatest runoff production were located at the base of a primarily colluvial hill slope. The largest events at these sites occurred during periods of surface saturation (soil surface to a depth of at least 30 cm). These results suggest that nonwinter P management for these residual soils should focus on rare, large events. Nutrient management planning could be improved if runoff estimation methods were to better integrate information on subsurface and upslope soil hydrologic properties.
Major Causes of Saudi Learners' Speaking Anxiety in EFL Classrooms

Since oral participation is one of the most observable phenomena in language classes, it has been noticed that students often suffer from a considerable level of anxiety in EFL classrooms. Although numerous studies have tackled this issue, particular attention to Saudi learners' perspectives of the main causes of speaking anxiety is needed. Therefore, this research aims to explore the main causes of speaking anxiety that Saudi EFL learners encounter in their language classrooms. The sample of this study involved 126 ELI Saudi female students studying their foundation year at King Abdul Aziz University and whose ages range between 18 to 20 years old. To reach a better and clear understanding of the research phenomenon, a mixed- method approach was used. For gathering data, two instruments were utilized; a semi-structured interview with ten students from level 102, 103, and 104 and an online based questionnaire with 116 students from level 102 and 103. The quantitative data were analyzed through descriptive statistics, and the qualitative data were thematically analyzed. The qualitative data found that the main causes of speaking anxiety were: Teachers' role in raising or reducing anxiety, lack of vocabulary, the weak educational system at schools, test anxiety, and peer anxiety. On the other hand, the quantitative data categorized speaking anxiety into three main domains: causes related to the classroom atmosphere, causes related to the EFL teachers, and others related to the test.
Face Image Manipulation Detection

This paper proposes a CNN-based (Convolutional Neural Network based) network to detect altered face picture, which can cover the most common face swap methods. The network uses an autoencoder which is pre-trained on the original images to reconstruct the input images. The reconstructed one and the input image are then processed by the SRM filter which can extract the noise distribution of images. We then feed the minus result of two processed results into a CNN architecture to predict whether the input image is original or tampered. The model was trained and evaluated in FaceForensics dataset and state-of-art face swap method. Experimental results demonstrate the effectiveness of our network.

The singular limit of a vector-valued reaction-diffusion process

We study the asymptotic behaviour of the solution to the vector– valued reaction–diffusion equation e∂tφ− e4φ + 1 e W,φ(φ) = 0 in ΩT , where φe = φ : ΩT := (0, T )×Ω −→ R2. We assume that the the potential W depends only on the modulus of φ and vanishes along two concentric circles. We present a priori estimates for the solution φ, and, in the spatially radially symmetric case, we show rigorously that in the singular limit as e → 0, two phases are created. The interface separating the bulk phases evolves by its mean curvature, while φ evolves according to a harmonic map flow on the respective circles, coupled across the interfaces by a jump condition in the gradient.
Sociological Factors as Predictors of Academic Emotion among Nigeria University Students

This study investigated the sociological factors as predictors of academic emotion among Nigeria University students. The study adopted a survey research design. The participants in the study were 345 undergraduates in South-West, Nigeria. Their age ranged between 17 years and 24 years with mean age of 21.69 years. Three valid and reliable instruments were used to assess academic emotion, parental involvement and social support while birth order was assessed by requesting the participants to fill out a short family history form as part of a battery of sociological tests. Descriptive statistics, Pearson’s Product Moment Correlation and multiple regression analysis were used to analyse the data. The result revealed that parental involvement, social support and birth order were potent predictors mildly associated to academic emotion. The study has implications for behaviour therapist, educational psychologists, educational stakeholders, government and parents on how challenges faced by student under a serious emotional strain which are virtually involved in every aspect of teaching and learning process can be reduced and well managed.
Barriers to patient education and their relationship to nurses’ perceptions of patient education climate

A core component of patient-centered care is effective patient education. Although it is a part of professional nursing and has been found to promote high-quality healthcare, its implementation is often deficient. This study responds to the need for theory-based research on health communication and aims to provide a theoretical framework for understanding nurses’ barriers to patient education. Drawing on organizational climate theory, the study examines two possible predictors of barriers to effective patient education, namely nurses’ perceptions of patient education climate, and of their role as patient educators. The hypotheses were tested using a cross-sectional correlational design with a sample of 328 nurses from 26 units in one general hospital. Data were obtained by means of questionnaires. The results supported our hypotheses, as each predicting variable was significantly related to the relevant barriers to patient education: i.e. patient education climate perceptions predicted the barriers of overload, lack of policies, and low priority, whereas role perception predicted the barriers of difficulty in communication with patients, insufficient professional knowledge and skills, and the belief that educating patients was not the nurse’s responsibility. To conclude, this study attributes the concept of patient education to organizational climate theory and, thus, may offer a theoretical framework for understanding the reluctance of hospital nurses to provide their patients with effective education. Practical implications for reducing barriers to patient education are discussed.
Growth Behavior of Phytopathogen Clavibacter michiganensis ssp. sepedonicus Treated with Selenium Biocomposites of Mushroom Origin

The results of studying the effect of biologically obtained selenium nanocomposites on the bacterium Clavibacter michiganensis ssp. sepedonicus (Cms) are presented. Cms is a Gram-positive bacterium, which causes one of the most dangerous potato diseases, ring rot. The effective alongside ecologically safe methods for combating Cms are lacking. As the agents feasible for use in this purpose, we examined the selenium nanocomposites obtained from the macrobasidiomycetes' submerged cultures. For exploring the bionanocomposites effect on Cms, the methods of agar well diffusion, the suspension turbidity measurement, and the colony-forming units count were applied. The results showed that all the nanocomposites under study lowered the bacterial suspension's absorption values compared to the reference specimen, that testified to the observation of bacteriostatic effect of the agents tested. The suppression action of nanocompostes was elucidated by means of both agar well diffusion assay and colony-forming units count. Thus, the results obtained demonstrate the occurrence of bacteriostatic and bactericidal effects of the substances under study, and favor the supposition on advisability of further research into the selenium nanocomposites as the agents for agricultural recovery from the bacterial pathogens.
TIME SERIES ANALYSIS OF INTERACTION BETWEEN AGGREGATE EXPENDITURE AND JOB CREATION IN SOUTH AFRICA

Jobs are the pillars of the economy and aggregate expenditure is among the key factor used to create an employment stimulating environment. This study scrutinizes the relationship between the component of aggregate expenditure and job creation in South Africa form 1995 to 2014. The Vector Autoregressive (VAR) model and multivariate co-integration approach were employed to examine how household consumption, government, investment and export expenditures affect job creation in South Africa. Findings of this study revealed that there is long-run relationship between aggregate expenditure and job creation with government and investment expenditure being the key determinants of job creation in South Africa. Contrary to priori expectation, consumption and exports do not improve jobs creation in South Africa. In the short-run, there are no significant interactions between components of aggregate expenditure and job creation. This study provided recommendation that may assist in boosting job creation in South Africa.
Students’ Social Origins and Targeted Grade Inflation

Grade inflation or soft grading is a common feature of the educational systems of many countries. In this paper I analyse grade inflation in a setting in which students differ in social background, and the grading policy can be targeted according to student type. I consider a signalling game where firms decide whether to hire students and their salary after observing their grades and social background, a university can inflate grades, when students decide whether to attend university. A targeted grade inflation may have redistributive effects by raising the salary of students with disadvantaged social background, if their grades are less inflated than other students'.

^Äëíê~ÅíK= This paper presents the initial study on ultrasonic tomography for multiphase flow application to investigate ability of ultrasonic tomography for used in monitoring the three phase flow (solid/liquid/gas) at once since there are no research on this conducted yet. In this project, eight units of 40 kHz ultrasonic sensors were mounted non-invasively around the pipe wall where four of it acts as a transmitter and the other four as a receiver. Each transmitter will transmit two cycles of pulses of 40 kHz at an excitation voltage of 24Vp-p. By using transmission-mode and fan-shaped beam projection approach, the peak to peak voltage of the received ultrasonic wave are measured. The investigation was based on the transmission and reception of sensors that were mounted circularly on the surface of experiment vessel. The results obtained throughout this research project had shown that different flow condition and composition will gives different value of output voltage. And the information and analysis of the results can be used for further investigation on the three phase system.

LONG-TIME MEASUREMENT OF LOADS ON THREE PIPE CULVERTS

The primary purpose of this paper is to describe and present the results of an experiment in which the loads on three 44-in. OD pipe culverts were measured during a 21-year period from 1927 to 1948. The 3 culverts of concrete, cast iron, and corrugated steel were under a 15-ft embankment. The measured loads are compared with loads calculated by the Marston theory of loads on underground conduits. In addition, settlement measurements of the soil at several horizontal planes in the embankment were made for the purpose of verifying the concept of a "plane of equal settlement," which was discovered by Marston on the basis of pure mathematical reasoning and which plays such an important role in the theory. The measured settlements were also used to determine actual values of the settlement ratio for use in calculating loads on the pipelines. A review of the theory is presented, particularly the mathematical determination of the height of the plane of equal settlement above the top of the conduit. The comparison between measured and calculated loads indicates the general correctness and reliability of the Marston theory. It is also shown that there is a substantial difference between loads on a flexible conduit and those on a rigid conduit because of the difference in values of the settlement ratios that are characteristic of those conduit types. The 21-year measurements of load indicated no substantial increase or decrease of load in that period of time.
