Development of Oil Production Forecasting Method based on Deep Learning

Identification of the quick declines of the desirable production fluids and rapid increases of the undesirable fluids are the production problems of the oil wells. The main purpose of this work is to develop a method that can forecast oil production with high accuracy, using Deep neural networks based on the debt data of the wells. In this paper, a hybrid model based on a combination of the CNN (Convolutional Neural Network) and LSTM (Long Short-Term Memory) networks, called CNN-LSTM is proposed for the forecasting of oil production time series. The architecture of the proposed CNN-LSTM model is hierarchical. Here, at first the CNN layer of the model is applied to the current time window, then the relationship between the time windows is predicted by applying the LSTM. The challenges of time series prediction often come from the continuity duration of every state. In order to overcome this problem, we try to predict temporal dependency in the certain time window. This issue is solved by the application of the CNN algorithm. Evaluation efficiency of the proposed model is performed on the QRI dataset. The prediction accuracy of the method is tested by RMSLE loss function and the best results are obtained using our proposed in the testing process.
Water Quality of Selected Fishing Beaches of Lake Victoria Kenyan Gulf

Lake Victoria the second largest fresh water body in the world located in East Africa is a shared resource between Kenya, Tanzania and Uganda and enjoys a wide range of streams and rivers from as far as Burundi and Rwanda. The lake has environmentally undergone physical, chemical and biological changes in the last four decades, particularly rise in its trophic condition and decline in oxygen level, which affects the water quality and fish population dynamics. This study therefore set out to determine the quality of water in selected fishing beaches of Lake Victoria, Kenya with a view to report the possible pollution levels. pH was highest at Nyamasari and Kotieno (9.3 ± 0.1) and lowest at Nyachebe and Kichinjio (7.08 ± 0.1) whereas temperature was highest at Nyamasari (29.5°C ± 0.0°C) and lowest at Kichinjio (23.4°C ± 0.2°C). DO was highest at Kotieno (10.3 ± 0.2 mgL) and lowest at Seka (2.4 ± 0.1 mgL). Turbidity was highest at Uyoga (125.5 ± 0.90 NTU) and lowest at Osieko (2.7 ± 0.1 NTU). Ammoniacal nitrogen was highest at Dunga (1278.3 ± 0.8 μ∙gl-1) and lowest at Nyamasari (12.4 ± 0.8), all a factor of human activities, lake substratum and effluents from rivers and surface runoff. All parameters assessed showed significant differences across sampling sites and depth except pH which did not vary significantly with distance from lakeshore. Further, all parameters did not show a clear pattern with respect to distance from the lakeshore possibly due to adequate mixing in the gulf. There is a need for further water quality monitoring by seasons to inform policy decisions towards sustainable lake exploitation.
Public Perceptions of Sentencing: National Survey Report

The research aims to advance understanding of current public knowledge about and attitudes towards sentencing. The research investigated: ▪How lenient/punitive current sentencing is perceived to be ▪Views on what the purposes of sentencing should be (in general and in specific types of cases – for example, sentencing young people) ▪The accuracy of beliefs about current sentencing (e.g. the proportion of custodial sentences given) ▪Views on what sentences ought to be given to particular offences (namely death by driving offences and sexual offences) ▪How public views on sentencing vary depending on specific mitigating and aggravating factors ▪Awareness of different sentencing options.
A novel randomized recurrent artificial neural network approach: recurrentrandom vector functional link network

The random vector functional link (RVFL) has successfully been employed in many applications since 1989. RVFL has a single hidden layer feedforward structure that also has direct links between the input layer and the output layer. Although nonlinearity, high generalization capacity, and fast training ability can be provided in RVFL, it can be found from the literature that higher nonlinearity can be obtained by adding recurrent feedback to an artificial neural network. In this paper, the recurrent type of RVFL (R-RVFL), which has both outer feedbacks and also inner feedbacks, is proposed. In order to evaluate and validate the proposed approach, a total of 109 public datasets were employed. Obtained results showed that R-RVFL can be employed successfully in terms of obtained success rates.
Acceptance of YouTube Applied to Dance Learning

The application of social media in education, including the learning of artistic performance, is becoming increasingly popular. The research on the acceptance of artistic performance through social media is accumulating. Therefore, this study employs an integrated approach based on the technology acceptance model (TAM) to examine dance learners experiencing YouTube by combining design features and factors to explore the acceptance. A survey from the online dance learning fellowship was distributed to recruit YouTube users. Confirmatory factor analysis was adopted to confirm reliability and validity, and a structural equation modeling test by VisualPLS with maximum likelihood estimation was performed to identify the relationships among the constructs. The results suggest that attitudes toward learning dance positively contribute to both perceived usefulness and ease of use of YouTube. Also, both of the factors are important in terms of enhancing YouTube users’ attitudes. Furthermore, positive relationships exist between YouTube users’ attitudes toward using and intention to use. This study contributes to the extant literature by identifying the decisive impact of the acceptance of YouTube applied to dance learning, and a new perspective extending the TAM by measuring YouTube users’ experience of intention to use is provided as a reference for further studies.
The Prognostic Role of Tumor-Infiltrating Lymphocytes CD8 and Foxp3and their Impact on Recurrence in Breast Cancer Patients

Background: The presence of tumor- infiltrating lymphocytes (TIL) within tumor epithelium or stroma of breast cancer is a surrogate of an immune response to cancer development, but their significance remains controversial. We conducted this study to evaluate the correlation of CD8+ (cytotoxic T) lymphocyte infiltration and Foxp3+ Tregs and tumor characteristics and their impact on recurrence in patients with invasive breast cancers. Patients and methods: CD8+ T cells and Foxp3+ Tregs were detected by immunohistochemistry using the paraffin-embedded tumor tissues from 68 patients with stage (I to III) breast cancer. Clinicopathological data including patient’s age, tumor size and grade, stage, lymph node metastasis, estrogen and progesterone receptor status, Ki-67, and human epidermal growth factor receptor-2/neu, and recurrence were reviewed. Results: The decreased mean number of CD8+ T cells was significantly associated with tumors with lymph node metastasis (P=0.02), and immune-positivity of Ki-67 (P=0.00). The increased number of Foxp3+ Tregs was significantly correlated with tumors with lymph node metastasis (P=0.01) higher stage (stage III, P=0.03), and immune-positivity for Ki-67 (P=0.02). Further analysis of the correlation using CD8+ T-cell/Foxp3+ Treg ratio showed significant correlation with tumors with lymph node metastasis(P=0.01), and immune-positivity of Ki-67 (P=0.00). Also, there were significant correlations between the increased Foxp3+Treg /CD4+ T-cell ratio and lymph node metastasis (P=0.00), and immune-positivity of Ki-67 (P=0.02). Conclusions: Data showed that lymph node metastases, tumor stage, immunopositivity of Ki67, and nontriple- negative tumors were associated with high regulatory T-cell infiltration. The prognostic role of immunologic balance as a marker for recurrence must be evaluated more clearly in a larger study.
Comparison of Hemilaminectomy and Mini-Hemilaminectomy in Dogs with Thoracolumbar Intervertebral Disc Extrusion using Computed Tomography and Magnetic Resonance Imaging: An Anatomical and Radiological Study

COMPARISON OF HEMILAMINECTOMY AND MINI-HEMILAMINECTOMY IN DOGS WITH THORACOLUMBAR INTERVERTEBRAL DISC EXTRUSION USING COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING: AN ANATOMICAL AND RADIOLOGICAL STUDY Jonathan Huska Co-Advisor: Luis Gaitero University of Guelph, 2012 Co-Advisor: Brigitte Brisson This thesis is an investigation of the access provided to the vertebral canal in dogs by the hemilaminectomy and mini-hemilaminectomy surgical techniques using computed tomography (CT), and the completeness of evacuating extruded material in dogs with intervertebral disc (IVD) extrusion using magnetic resonance imaging (MRI). Hemilaminectomy and mini-hemilaminectomy were performed on opposite sides of the spine at T11-T12, T13-L1, and L2-L3 in 10 cadavers. Measurements of the vertebral canal height, defect height, and any dorsal and ventral remnants of the vertebral arch were obtained by CT. A covariate analysis was used to compare measurements with the surgical technique, surgical site, and side of the vertebral column. Defect height was greater with hemilaminectomy due to a smaller dorsal lamina remnant. There was no statistical difference in the height of the ventral remnant, or with surgical site. Nineteen prospectively recruited dogs with suspected IVD extrusion were randomly assigned to hemilaminectomy (10 dogs) or mini-hemilaminectomy (9 dogs) groups. Intervertebral disc extrusion was identified pre-operatively with MRI and later confirmed surgically, and immediate post-operative MRI was performed at the surgical site. The volume of extruded IVD material preand post-operative was calculated from transverse T2 images. Although residual IVD material was present in post-operative images from all dogs in the hemilaminectomy group and only 4 in the mini-hemilaminectomy group, there was no statistically significant difference between the proportionate volumes of material removed by either technique. The median residual volume with hemilaminectomy was 13.6% (confidence interval: 7.8 – 23.6%), and with mini-hemilaminectomy was 7.7% (4.3 – 13.8%). The results of this study confirm that the difference in the defect height between techniques is related to the removal of the articular processes creating a larger defect along the dorsal vertebral canal, while no difference in access to the ventral canal was observed. No effect of vertebral site was detected suggesting neither procedure provides an advantage over the other due to location of the lesion along the thoracolumbar spine. Residual extruded IVD material occurs with both techniques; while no statistical difference was noted, a larger population should be examined.
Impact of the perception of performance appraisal practices on individual innovative behavior

PurposeThe purpose of this paper is to analyze the impact of employees’ perception of performance appraisal (PA) practices on innovative behavior (IB). The authors also propose to analyze consistency, a dimension of Human Resource Management (HRM) system strength, as a moderating variable in the aforementioned relationship.Design/methodology/approachA quantitative study was conducted, using a sample of 166 employees carrying out highly qualified, intensive knowledge jobs in four industrial companies in the Valencian region of Spain. The hypotheses were tested by applying the Smart-PLS 3.2 software.FindingsThe findings confirmed that in a context of professional and qualified work, PA practices have a direct and positive effect on IB. However, the results obtained did not enable us to affirm that employee perceptions of the consistency of the HR system moderated the relationship between PA and IB.Originality/valueThe paper’s originality lies in including the role of consistency, a dimension of HRM system strength, in the analyzed relationship. When employees believe that PA achieves the goals for which this practice was designed, and that this appraisal follows a clear strategic direction over time, they perceive that the assessment system is not arbitrary, i.e., that this HR practice is being applied consistently. Consequently, the present work shows the relevant role of the perception of consistent PA when the firm wants to encourage IB. This fact opens up the field to study how to define and implement control mechanisms that tell managers whether there is a fit between employees’ perceptions and the intentionality of the HRP these managers have defined.
A preliminary analysis modeling of the relationship between quality management practices and sustainable performance

Abstract From the past literature, the relationship between quality practices and sustainable performance has not adequately been explored. Hence, this research attempted to further investigate the impacts of other variables that may proffer better explanation to the nature of the relationship. Therefore, the aim of this study is to examine the mediating and moderating effect of organizational excellence and environmental regulation and policy (ERP) on the relationship between TQM (quality practices) and sustainable performance by proposing an inclusive research model comprising the antecedent factors in food and beverage industry of Malaysia. Questionnaires were distributed to 303 Malaysian food and beverages companies while 168 questionnaires were returned (response rate above 50%) and PLS-SEM was used to analyze the data in order to assess the validity and reliability of the instrument. This study serves as a validation process for the developed instruments of the research with the identified constructs of the study while the preliminary analysis and results are shown. Also, the result reveals that the instruments are reliable and the analysis indicates a strong evidence of rational validity. Similarly, it reaffirms the importance of excellence for any successful strategic implementation in enhancing sustainable performance through the implementation of quality practices.
Crypsis Decreases with Elevation in a Lizard

Predation usually selects for visual crypsis, the colour matching between an animal and its background. Geographic co-variation between animal and background colourations is well known, but how crypsis varies along elevational gradients remains unknown. We predict that dorsal colouration in the lizard Psammodromus algirus should covary with the colour of bare soil—where this lizard is mainly found—along a 2200 m elevational gradient in Sierra Nevada (SE Spain). Moreover, we predict that crypsis should decrease with elevation for two reasons: (1) Predation pressure typically decreases with elevation, and (2) at high elevation, dorsal colouration is under conflicting selection for both crypsis and thermoregulation. By means of standardised photographies of the substratum and colourimetric measurements of lizard dorsal skin, we tested the colour matching between lizard dorsum and background. We found that, along the gradient, lizard dorsal colouration covaried with the colouration of bare soil, but not with other background elements where the lizard is rarely detected. Moreover, supporting our prediction, the degree of crypsis against bare soil decreased with elevation. Hence, our findings suggest local adaptation for crypsis in this lizard along an elevational gradient, but this local adaptation would be hindered at high elevations.
The neural basis for a persistent internal state in Drosophila females

Sustained changes in mood or action require persistent changes in neural activity, but it has been difficult to identify and characterize the neural circuit mechanisms that underlie persistent activity and contribute to long-lasting changes in behavior. Here, we focus on changes in the behavioral state of Drosophila females that persist for minutes following optogenetic activation of a single class of central brain neurons termed pC1. We find that female pC1 neurons drive a variety of persistent behaviors in the presence of males, including increased receptivity, shoving, and chasing. By reconstructing cells in a volume electron microscopic image of the female brain, we classify 7 different pC1 cell types and, using cell type specific driver lines, determine that one of these, pC1-Alpha, is responsible for driving persistent female shoving and chasing. Using calcium imaging, we locate sites of minutes-long persistent neural activity in the brain, which include pC1 neurons themselves. Finally, we exhaustively reconstruct all synaptic partners of a single pC1-Alpha neuron, and find recurrent connectivity that could support the persistent neural activity. Our work thus links minutes-long persistent changes in behavior with persistent neural activity and recurrent circuit architecture in the female brain.
Robust Visual Tracking via Constrained Multi-Kernel Correlation Filters

Discriminative Correlation Filter (DCF) based trackers are quite efficient in tracking objects by exploiting the circulant structure. The kernel trick further improves the performance of such trackers. The unwanted boundary effects, however, are difficult to solve in the kernelized correlation models. In this paper, we propose a novel Constrained Multi-Kernel Correlation tracking Filter (CMKCF), which applies spatial constraints to address this drawback. We build the multi-kernel models for multi-channel features with three different attributes, and then employ a spatial cropping operator on the semi-kernel matrix to address the boundary effects. For the constrained optimization solution, we develop an Alternating Direction Method of Multipliers (ADMM) based algorithm to learn our multi-kernel filters efficiently in the frequency domain. In particular, we suggest an adaptive updating mechanism by exploiting the feedback from high-confidence tracking results to avoid corruption in the model. Extensive experimental results demonstrate that the proposed method performs favorably on OTB-2013, OTB-2015, VOT-2016 and VOT-2018 dataset against several state-of-the-art methods.
Do extrinsic motivation and organisational culture additively strengthen intrinsic motivation in online knowledge sharing?

This study aims to examine the relationship between intrinsic motivation and online knowledge sharing intentions (KSIs) and the moderating effect of extrinsic motivation and organisational culture on this relationship. The influence of online KSI on two dimensions of online knowledge sharing behaviour, knowledge donating and knowledge collecting, was also investigated. ,Based on the extensive literature review, a questionnaire was designed. In total, 290 questionnaires from employees in Vietnamese companies in the banking and insurance industry were collected and tested using structural equation modelling. Statistical analysis was conducted using SPSS and PLS 3 software to examine the research hypotheses. ,This study found that rewards and reciprocity undermined the influence of self-enjoyment on online KSI, while top management support and social interaction ties undermined the relationship between self-efficacy and online KSI. Top management support positively moderated the effect of self-enjoyment on online KSI. The results also suggested that online KSI was a good predictor of online knowledge donating and collecting. ,Little is empirically known about the moderating effect of extrinsic motivation and organizational culture on intrinsic motivation. The study brings new insights to further understand about online knowledge sharing in an organisation.
The Influence of Initial Blood Triglyceride Concentrations on the Change in Blood Lipids Following an Acute Bout of Exercise

MCGLYNN, MARK L. , M.S., June 2011, Physiology of Exercise, Research The Influence of Initial Blood Triglyceride Concentrations on the Change in Blood Lipids Following an Acute Bout of Exercise Director of Thesis: Michael R. Kushnick The purpose of this investigation was to compare the absolute and relative acute exercise responses in average fitness men with lower (LOW = 43.33 ± 10.31) and higher (HIGH = 151.34 ± 28.90) initial triglycerides (TG) after expending 600kcal on a treadmill. All participants were screened for average fitness (47.37 ± 3.55) and body composition (19.14 ± 3.49), then completed a treadmill jog at 60% of their VO2max and blood draws at 1 (1hPE), 24 (24hPE) and 48 (48hPE) hours postexercise. This investigation demonstrated significant absolute (mg/dl) TG reductions among groups with initially different TG values; however, these differences were relatively equal when considering the percent change. Secondly, groups divided solely on initial TG values had different postexercise HDL-C responses. This investigation adds to the growing body of literature in support of exercise‟s beneficial influence over blood lipids and contributes towards a need for further research into the TG-HDL-C relationship.

Advancing Theory with Review Articles

Reviewing a body of work presents unique opportunities for making a theoretical contribution. Review articles can make readers think theoretically differently about a given field or phenomenon. Yet, review articles that advance theory have been historically under‐represented in Journal of Management Studies. Accordingly, the purpose of this editorial is to propose a multi‐faceted approach for fashioning theoretical contributions in review articles, which we hope will inspire more authors to develop and submit innovative, original, and high‐quality theory‐building review articles. We argue that advancing theory with review articles requires an integrative and generative approach. We propose a non‐exhaustive set of avenues for developing theory with a review article: exposing emerging perspectives, analysing assumptions, clarifying constructs, establishing boundary conditions, testing new theory, theorizing with systems theory, and theorizing with mechanisms. As a journal, Journal of Management Studies is a journal of ideas – new ideas; ideas drawn from reflections on extant theory and ideas with potential to change the way we understand and interpret theory. With this in mind, we think that advancing theory with review articles is an untapped source of new ideas.
