    Mutual Fund Theorem for continuous time markets with random coefficients.Nikolai Dokuchaev - 2014 - Theory and Decision 76 (2):179-199.
    The optimal investment problem is studied for a continuous time incomplete market model. It is assumed that the risk-free rate, the appreciation rates, and the volatility of the stocks are all random; they are independent from the driving Brownian motion, and they are currently observable. It is shown that some weakened version of Mutual Fund Theorem holds for this market for general class of utilities. It is shown that the supremum of expected utilities can be achieved on a sequence (...)

    The cardinal coefficients of the Ideal If{{\mathcal {I}}_{f}}.Noboru Osuga & Shizuo Kamo - 2008 - Archive for Mathematical Logic 47 (7-8):653-671.
    In 2002, Yorioka introduced the σ-ideal ${{\mathcal {I}}_f}$ for strictly increasing functions f from ω into ω to analyze the cofinality of the strong measure zero ideal. For each f, we study the cardinal coefficients (the additivity, covering number, uniformity and cofinality) of ${{\mathcal {I}}_f}$.

    Inferring beliefs as subjectively imprecise probabilities.Steffen Andersen, John Fountain, Glenn W. Harrison, Arne Risa Hole & E. Elisabet Rutström - 2012 - Theory and Decision 73 (1):161-184.
    We propose a method for estimating subjective beliefs, viewed as a subjective probability distribution. The key insight is to characterize beliefs as a parameter to be estimated from observed choices in a well-defined experimental task and to estimate that parameter as a random coefficient. The experimental task consists of a series of standard lottery choices in which the subject is assumed to use conventional risk attitudes to select one lottery or the other and then a series of betting choices (...)

    Gradualism, natural selection, and the randomness of mutation–fisher, Kimura, and Orr, connecting the dots.Matthew J. Maxwell & Elliott Sober - 2023 - Biology and Philosophy 38 (2):1-22.
    Evolutionary gradualism, the randomness of mutations, and the hypothesis that natural selection exerts a pervasive and substantial influence on evolutionary outcomes are pair-wise logically independent. Can the claims about selection and mutation be used to formulate an argument for gradualism? In his Genetical Theory of Natural Selection, R.A. Fisher made an important start at this project in his famous “geometric argument” by showing that a random mutation that has a smaller effect on two or more phenotypes will have a (...)

  6. Non-linear mixed logit.Steffen Andersen, Glenn W. Harrison, Arne Risa Hole, Morten Lau & E. Elisabet Rutström - 2012 - Theory and Decision 73 (1):77-96.
    We develop an extension of the familiar linear mixed logit model to allow for the direct estimation of parametric non-linear functions defined over structural parameters. Classic applications include the estimation of coefficients of utility functions to characterize risk attitudes and discounting functions to characterize impatience. There are several unexpected benefits of this extension, apart from the ability to directly estimate structural parameters of theoretical interest.

    Adaptive Finite-Time Fault-Tolerant Control for Half-Vehicle Active Suspension Systems with Output Constraints and Random Actuator Failures.Jie Lan & Tongyu Xu - 2021 - Complexity 2021:1-16.
    The problem of adaptive finite-time fault-tolerant control and output constraints for a class of uncertain nonlinear half-vehicle active suspension systems are investigated in this work. Markovian variables are used to denote in terms of different random actuators failures. In adaptive backstepping design procedure, barrier Lyapunov functions are adopted to constrain vertical motion and pitch motion to suppress the vibrations. Unknown functions and coefficients are approximated by the neural network. Assisted by the stochastic practical finite-time theory and FTC theory, (...)

    Board Meeting Attendance by Outside Directors.Byung S. Min & Amon Chizema - 2018 - Journal of Business Ethics 147 (4):901-917.
    Outside directors’ regular board meeting attendance is important in improving the effectiveness of a governance system. Such attendance is evidence of their commitment to the firm as key other players in monitoring and decision making. Using a unique dataset for Korean firms, and three-level random coefficients models, we find that, foreign outside directors, an independent appointment process, professional knowledge of business operations and accumulated firm-specific knowledge are important factors that affect outside directors’ attendance of board meetings. The results (...)

    A Cross Level Investigation on the Linkage Between Job Satisfaction and Voluntary Workplace Green Behavior.Andrea Kim, Youngsang Kim & Kyongji Han - 2019 - Journal of Business Ethics 159 (4):1199-1214.
    Building on the broaden-and-build theory of positive emotions and on social role theory, this research investigates the linkages among prior job satisfaction, voluntary workplace green behavior, and subsequent job satisfaction as dependent on work group gender composition. With a multi-source, multi-time dataset, our random coefficient modeling demonstrated that job satisfaction positively predicts VWGB and that this pattern is more salient in work groups with more females. In addition, while VWGB does not yield job satisfaction in a subsequent time period, (...)

    The Association Between Toddlers’ Temperament and Well-Being in Norwegian Early Childhood Education and Care, and the Moderating Effect of Center-Based Daycare Process Quality.Catharina P. J. van Trijp, Ratib Lekhal, May Britt Drugli, Veslemøy Rydland, Suzanne van Gils, Harriet J. Vermeer & Elisabet Solheim Buøen - 2021 - Frontiers in Psychology 12.
    Children who experience well-being are engaging more confidently and positively with their caregiver and peers, which helps them to profit more from available learning opportunities and support current and later life outcomes. The goodness-of-fit theory suggests that children’s well-being might be a result of the interplay between their temperament and the environment. However, there is a lack of studies that examined the association between children’s temperament and well-being in early childhood education and care, and whether this association is affected by (...)

    The Influence of Founder CEO’s Human Capital Resources on the Relationship Between Workforce Gender Diversity and Venture Firm Performance.Eun-Ji Oh, Youngsang Kim & Yangxin Wang - forthcoming - Journal of Business Ethics:1-22.
    Integrating the categorization-elaboration model (CEM), resource complementarity, and human capital perspectives, we investigate whether the founder CEO’s human capital resources can influence the effect of workforce gender diversity, an untapped strategic resource, on venture firm performance. Our main focus lies on knowledge- and technology-intensive venture firms, and we propose that both workforce gender diversity and the CEO’s human capital resources jointly influence venture firm performance. We identify the specific functional impacts of the founder CEO's human capital, encompassing entrepreneurial experience, human (...)

    A general non-linear multilevel structural equation mixture model.Augustin Kelava & Holger Brandt - 2014 - Frontiers in Psychology 5:75570.
    In the past 2 decades latent variable modeling has become a standard tool in the social sciences. In the same time period, traditional linear structural equation models have been extended to include non-linear interaction and quadratic effects (e.g., Klein and Moosbrugger, 2000 ), and multilevel modeling (Rabe-Hesketh et al., 2004 ). We present a general non-linear multilevel structural equation mixture model (GNM-SEMM) that combines recent semiparametric non-linear structural equation models (Kelava and Nagengast, 2012 ; Kelava et al., 2014 ) with (...)

    Model driven quantification of individual and collective cell migration.Caroline Rosello, Pascal Ballet, Emmanuelle Planus & Philippe Tracqui - 2004 - Acta Biotheoretica 52 (4):343-363.
    While the control of cell migration by biochemical and biophysical factors is largely documented, a precise quantification of cell migration parameters in different experimental contexts is still questionable. Indeed, these phenomenological parameters can be evaluated from data obtained either at the cell population level or at the individual cell level. However, the range within which both characterizations of cell migration are equivalent remains unclear. We analyse here to which extent both sources of data could be integrated within a unified description (...)

    The relation between coping style and posttraumatic growth among patients with breast cancer: A meta-analysis.Xiao Wan, Haitao Huang, Qianwen Peng, Yiming Zhang, Jiwei Hao, Guangli Lu & Chaoran Chen - 2022 - Frontiers in Psychology 13.
    Posttraumatic growth has been correlated with coping style among patients with breast cancer. However, to date, there is no consensus on the extent to which coping style is associated with PTG in patients with breast cancer. Therefore, we performed a meta-analysis to quantitatively synthesize previous findings. Based on the PRISMA method, this study employed a random effects model using the Stata software to calculate the pooled correlation coefficient and examined a range of moderators: cancer stage, publication type, participants’ age, (...)

    Cronbach’s Alpha and Semantic Overlap Between Items: A Proposed Correction and Tests of Significance.Ghadah S. Alkhadim - 2022 - Frontiers in Psychology 13.
    The purpose of the present study was to address the shortcomings of Cronbach’s alpha concerning the semantic overlap between items. Using an example from a motivational measure, the correction of Cronbach’s alpha was applied by partialing out the effects due to conceptual overlap. The significance of Cronbach’s alpha was tested using simulated random data derived from the measure and by estimating the confidence intervals with known and unknown distributions. The results indicated that the uncorrected conceptual overlap coefficient alpha was (...)

    Ethical leadership, psychological empowerment and caring behavior from the nurses’ perspective.Mojtaba Dehghani-Tafti, Maasoumeh Barkhordari-Sharifabad, Khadijeh Nasiriani & Hossein Fallahzadeh - 2022 - Clinical Ethics 17 (3):248-255.
    Background Care is the basis of the nursing profession and nurse’s caring behavior is one of the important factors in patient satisfaction. On the other hand, psychological empowerment can improve the provision of care services, and leaders have a significant impact on the behavior of followers. This study determined the correlation between ethical leadership, psychological empowerment, and caring behavior from nurses’ perspective. Methods This cross-sectional descriptive study was conducted in 2019. A total of 200 nurses were selected by stratified (...) sampling. Data were collected with ethical leadership, caring behavior and psychological empowerment questionnaires and analyzed with descriptive statistics (mean and standard deviation, frequency distribution) and inferential statistics (Pearson correlation coefficient, regression, and t-test) using SPSS20. Results The findings showed a significant correlation between ethical leadership, psychological empowerment (P < 0.001, r = 0.24) and caring behavior of nurses (P < 0.001, r = 0.25). Also, there was a significant correlation between psychological empowerment and nurses’ caring behavior (P = 0.002, r = 0.21). The regression analysis showed that ethical leadership and psychological empowerment are a predictor of caring behavior of nurses. Conclusion Applying an ethical leadership style by nursing managers can lead to nurses’ improved psychological empowerment and caring behaviors and ultimately, patient care quality. Thus, considering guidelines at the team and organizational levels and programs such as providing workshops and periodic counseling to cultivate ethical nurse leadership can lead to better caring behavior.

    Role of the Electromagnetic Vacuum in the Transition from Classical to Quantum Mechanics.Luis de la Peña & Ana María Cetto - 2022 - Foundations of Physics 52 (4):1-17.
    We revisit the nonrelativistic problem of a bound, charged particle subject to the random zero-point radiation field, with the purpose of revealing the mechanism that takes it from the initially classical description to the final quantum-mechanical one. The combined effect of the zpf and the radiation reaction force results, after a characteristic time lapse, in the loss of the initial conditions and the concomitant irreversible transition of the dynamics to a stationary regime controlled by the field. In this regime, (...)

    Extreme Gradient Boosting Algorithm for Predicting Shear Strengths of Rockfill Materials.Mahmood Ahmad, Ramez A. Al-Mansob, Kazem Reza Kashyzadeh, Suraparb Keawsawasvong, Mohanad Muayad Sabri Sabri, Irfan Jamil & Arnold C. Alguno - 2022 - Complexity 2022:1-11.
    For the safe and economical construction of embankment dams, the mechanical behaviour of the rockfill materials used in the dam’s shell must be analyzed. The characterization of rockfill materials with specified shear strength is difficult and expensive due to the presence of particles greater than 500 mm in diameter. This work investigates the feasibility of using an extreme gradient boosting computing paradigm to estimate the shear strength of rockfill materials. To train and validate the proposed XGBoost model, a total of (...)

    The challenge of heritability: genetic determinants of beliefs and their implications.Wade Munroe - 2020 - Inquiry: An Interdisciplinary Journal of Philosophy 63 (8):831-874.
    ABSTRACT Ethical and political attitudes are not randomly distributed in a population. Attitudes of family members, for example, tend to be more similar than those of a random sample of the same size. In the fields of social psychology and political science, the historically standard explanation for these attitude distribution patterns was that social and political attitudes are a function of environmental factors like parental socialization and prevailing social norms. This received view is, however, complicated by more recent work (...)

    Induction amplifiante et inference statistique.L. Féraud - 1949 - Dialectica 3 (1‐2):127-152.
    The basic assumptions in the physical theory of Brownian motion are analized and the arbitrary character of certain aspects of the current theories is emphasized. The most serious limitations of the theory arise from the fact that in the theory, the elementary processes of the individual collisions are nowhere discussed. However, it is shown that the encounters between stars under their Newtonian inverse square attractions considered in Stellar Dynamics provides, in virtue of the peculiar character of inverse square forces, a (...)

    A stochastic approach to the hadron spectrum. I.J. C. Aron - 1986 - Foundations of Physics 16 (10):1021-1060.
    In this paper the squared mass of the hadron is defined as a random variable, whose average is the measured quantity. This leads to a mass formula, of a unique type for mesons and baryons, with a general law for the spin variation of the coefficients. The central squared masses form an overall geometrical scheme; in the baryon case it contains trajectories which are a fine structure of the Regge trajectories. For the accurately measured masses the difference between (...)

    The Adjustment of Covariates in Cox’s Model under Case-Cohort Design.Guocai Rong, Luwei Tang, Wenting Luo, Qing Li & Lifeng Deng - 2020 - Complexity 2020:1-16.
    Case-cohort design is a biased sampling method. Due to its cost-effective and theoretical significance, this design has extensive application value in many large cohort studies. The case-cohort data includes a subcohort sampled randomly from the entire cohort and all the failed subjects outside the subcohort. In this paper, the adjustment for the distorted covariates is considered to case-cohort data in Cox’s model. According to the existing adjustable methods of distorted covariates for linear and nonlinear models, we propose estimating the distorting (...)

    Multilingual Speaker Identification by Combining Evidence from LPR and Multitaper MFCC.H. S. Jayanna & B. G. Nagaraja - 2013 - Journal of Intelligent Systems 22 (3):241-251.
    In this work, the significance of combining the evidence from multitaper mel-frequency cepstral coefficients, linear prediction residual, and linear prediction residual phase features for multilingual speaker identification with the constraint of limited data condition is demonstrated. The LPR is derived from linear prediction analysis, and LPRP is obtained by dividing the LPR using its Hilbert envelope. The sine-weighted cepstrum estimators with six tapers are considered for multitaper MFCC feature extraction. The Gaussian mixture model–universal background model is used for modeling (...)

    Study on Assessing the Evolution of Nutritional Choices through Social Media Influence.Dr Charu Wadhwa, Hemal Thakker, Vaibhav Kaushik, Honganur Raju Manjunath, Shobhit Goyal, Axita Thakkar & Madhur Grover - forthcoming - Evolutionary Studies in Imaginative Culture:860-869.
    Social media-related nutritional decisions influencers and commercial postings on social media have a significant impact on people's eating habits, purchasing decisions, and decisions about food in general. It also shapes people's dietary practices and overall nutrition. Investigating dietary habits through social media can be disadvantageous to the potential for biased or inaccurate information, as sensational content can lead to unreliable nutritional advice. The 160 participants' nutritional choices using social media influence data are collected, and random questionnaires are collected. There (...)

  47. On a stochastic version of a modified Nicholson-Baily model.J. Reddingius, S. A. Vries & A. J. Stam - 1982 - Acta Biotheoretica 31 (2).
    Deterministic models in population dynamics often are really approximations to stochastic models, justified by an appeal to the law of large numbers. It is proposed to call such models pseudodeterministic. Four questions are discussed in this article: (1) What errors may be made by equating deterministically predicted values to expectations? (2) When, and in what sense, may numbers be assumed to be large? (3) How large are the variances, coefficients of variations, etc., as assigned to the variables in the (...)

    The Nurses’ Second Victim Syndrome and Moral Distress.Esmat Shomalinasab, Zahra Bagheri, Azam Jahangirimehr & Fatemeh Bahramnezhad - 2023 - Nursing Ethics 30 (6):822-831.
    Background The increasing prevalence of moral distress in the stressful environment of the intensive care unit (ICU) provides grounds for nursing error and endangers patients’ health, safety, and even life. One of the most important reasons for this distress is the treatment team’s second victim syndrome (SVS), especially nurses, following errors in the treatment system. Objectives The present study aimed to determine the relationship between moral distress and SVS in ICUs. Research design This cross-sectional study involved a sample size of (...)

    Novel Node Centrality-Based Efficient Empirical Robustness Assessment for Directed Network.Xiaolong Deng, Hao Ding, Yong Chen, Cai Chen & Tiejun Lv - 2020 - Complexity 2020:1-14.
    In recent years, while extensive researches on various networks properties have been proposed and accomplished, little has been proposed and done on network robustness and node vulnerability assessment under cascades in directed large-scale online community networks. In essential, an online directed social network is a group-centered and information spread-dominated online platform which is very different from the traditional undirected social network. Some further research studies have indicated that the online social network has high robustness to random removals of nodes (...)

    Birth of a Fiction.Jean Ricardou & Erica Freiberg - 1977 - Critical Inquiry 4 (2):221-230.
    Nothing, one day, seemed more imperative to me than the project of composing a book whose fiction would be constructed not as the representation of some preexistent entity, real or imaginary, but rather on the basis of certain specific mechanisms of generation and selection. The principle of selection may be called overdetermination. It requires that every element in the text have at least two justifications. In this perspective, each element is invested with a coefficient of overdetermination. If there is a (...)
