1 Married and Cohabiting Parents ’ Relationship Stability : A Focus on Race and Ethnicity

We draw on three waves of the Fragile Families Study (N = 2,249) to examine family stability among a recent birth cohort of children. We find that children born to cohabiting versus married parents have over five times the risk of experiencing their parents’ separation. This difference in union stability is greatest for White children, as compared with Black or Mexican American children. For White children, differences in parents’ education levels, paternal substance abuse, and prior marriage and children account for the higher instability faced by those born to cohabiting parents, whereas differences in union stability are not fully explained among Black and Mexican American children. These findings have implications for policies aimed at promoting family stability and reducing inequality.
FirmGuide: Boosting the Capability of Rehosting Embedded Linux Kernels through Model-Guided Kernel Execution

Linux kernel is widely used in embedded systems. To understand practical threats to the Linux kernel, we need to perform dynamic analysis with a full-system emulator, e.g., QEMU. However, due to hardware fragmentation, e.g., various types of peripherals, most embedded systems are not currently supported by QEMU. Though some progress has been made on rehosting firmware, it mainly focuses on user space programs or simple real-time operating systems.The goal of this work is to boost the capability of rehosting the embedded Linux kernels in QEMU. By doing so, dynamic analysis systems can be firstly applied on embedded Linux kernels by leveraging off-the-shelf tools upon QEMU. Accordingly, we proposed a new technique called model-guided kernel execution. It combines the peripheral abstractions in the Linux kernel and kernel-peripheral interactions to semi-automatically generate peripheral models that are then used to synthesize new QEMU virtual machines to start the dynamic analysis.We have implemented a prototype called FirmGuide. It generates 9 peripheral models with full functionality and 64 with minimum functionality covering 26 SoCs. Our evaluation with 6,188 firmware images shows that it can successfully rehost more than 95% of Linux kernels in 2 architectures and 22 versions. None of them can be rehosted in the vanilla QEMU. The result of the LTP benchmark shows the reliability and robustness of the rehosted Linux kernels. We further conduct two security applications, i.e., vulnerability analysis and fuzzing, on the rehosted Linux kernels to demonstrate the usage scenarios.
Experimental Investigation of Solid Attitude Control System Using Proportional Pintle Thrusters

In order to investigate the characteristics of solid attitude control system (SACS) using proportional pintle thrusters, an ACS comprised of dual collaborative thrusters was designed and studied by theory and cold-flow test. Experiments were conducted to ascertain thrust variation at different pintle locations. With the purpose of studying thrust control principle, the thrust, chamber pressure and pintle displacement of two thrusters were measured, which worked differentially in the process. Results show that a nearly linear relationship is found between the thrust and valve pintle position and the two thrusters can work synchronous to produce a resultant force, whose direction and value can vary continuously. Besides, collaborative work mode of dual thrusters is conducive to the stabilization of chamber pressure which is beneficial to the choice of propellant.
Corporate Spirit as Secret Ingredient Proximity in Corporate Culture as Moderating Success Factor in Collaborations

Successful collaborations between organizations lead to effectiveness and economic growth. Accordingly, collaborating partners strive to optimize factors contributing to collaboration performance. Earlier research on collaboration offers a variety of success factors. However, there are still aspects, of which the effects are not completely clarified, as in the case of distance between collaborating organizations due to corporate culture. While the literature claims that economic activities are culturally embedded, investigations on the contribution of distance in corporate culture on economic interactions’ success remain superficial and unclear. Addressing this deficiency, the present paper investigates direct and indirect effects of distance in corporate culture on collaboration performance. Empirical evidence reveals a negative direct effect of distance in corporate culture. At the same time, as a moderator, high distance compensates for the negative effect of social distance, while proximity compensates for the negative effect of cognitive distance.
The Efficient Market Hypothesis in Developing Countries: Indonesia

By considering all the historical and developmental background of the efficiency market hypothesis, in this paper it will be a quick review on the evidence of the rejection of the hypothesis based on previously done studies and based on own investigations. The main object of the paper is about the determinations done on stock prices. It is thought that a high quality predictability of the stock prices has a huge role in the security market and in the whole macroeconomic policies of a country. The efficiency and predictability adjusted by the efficiency market hypotheses are violated in stock market, by emphasizing the fact that the future stock prices and returns are not estimated completely by the previous years’ data. In this paper, it is tried to find out other models done for returns and prices securities in Indonesia to prove the rejection of the hypothesis, that in fact it is implicated also in some other developing countries. The model of the stock prices and the other estimators by using the root test examine the weak form of the efficiency market hypothesis and confirm the rejection of the hypothesis. By the help of the Augmented Dickey-Fuller test and the Granger test of causality, it can be understood that market efficiency cannot be fully predictable and understandable, because it is a matter of the economic behavior.

THE TOPP-LEONE ODD EXPONENTIAL HALF LOGISTIC-G FAMILY OF DISTRIBUTIONS: MODEL, PROPERTIES AND APPLICATIONS

We developed a new generalized distribution referred to as the Topp-Leone Odd Exponential Half Logistic-G (TL-OEHL-G) distribution. The proposed distribution is an infinite linear combination of the exponentiated-G distribution. Some special cases from the TL-OEHL-G distribution are presented. The special cases of the TL-OEHL-G distribution apply to high skewed data and different forms of the hazard rate. Simulation study results for a selected special case are presented. Real data examples to demonstrate flexibility of the new model compared to other models are also provided.
INFLUENCE OF SEAL AND LINER HYDRAULIC PROPERTIES ON THE SEEPAGE RATE FROM ANIMAL WASTE HOLDING PONDS AND LAGOONS

Animal waste holding ponds and lagoons are often lined with soil and may leak leachate into the underlying media. Calculating the flux of leachate through a pond liner is typically predicted by applying Darcy’s law across the liner while assuming saturated conditions. The formation of a thin sealing layer atop holding pond liners is common due to the abundance of fines and organic material within animal waste. Research has shown that these seals are credited with reducing the flux from holding ponds by one or more orders of magnitude due to the very low hydraulic conductivity of the sealing layer. Because even compacted clay liners are likely to have hydraulic conductivities much larger than the overlying seal, a unit gradient forms within the liner such that it desaturates to the point that its unsaturated hydraulic conductivity is equal to the flux, a process similar to that of water infiltrating into a crusted soil. In this study, a two-layer (liner and seal) unsaturated model is presented for describing the flux of animal waste from holding ponds. The two-layer model predicts that flux is not a function of liner thickness, and is only a weak function of liner hydraulic conductivity. Instead, flux through the liner is primarily a function of seal hydraulic conductivity, seal thickness, and depth of waste. The van Genuchten-Mualem hydraulic parameters (. and n) of the liner are found to correlate well with flux, but the saturated hydraulic conductivity of the liner is found to be a poor predictor of flux.
Comparison of Impact Forces in High and Low Impact Aerobic Dance Movements

This study compared impact forces and loading rates in a high and low impact aerobic dance movement. Five subjects each performed five trials of the low impact front knee lift (LFKL) and five trials of the high impact front knee lift (HFKL). The data were recorded using an AMTI force plate at 1,000 Hz. A repeated-measures ANOVA was used to test for differences in selected variables for the LFKL and HFKL. Peak impact force was significantly lower in the LFKL than the HFKL, mean 0.98 BW and 1.98 BW, respectively. Mean loading rate was significantly lower in the LFKL (14.38 BW/s) than the HFKL (42.55 BW/s). Mean impact impulse during the first 50 ms of impact was significantly lower in the LFKL (0.0131 BW•s) than the HFKL (0.0295 BW•s). Based upon these differences in external ground reaction forces, it appears that low impact front knee lifts impose a significantly lower load than high impact front knee lifts.
Biomedical engineering minor: an option for EE students in Argentina

In accordance with federal laws, all engineering educational programs in Argentina must be approved by the National Commission on University Evaluation and Accreditation (CONEAU), as a pre-requisite for engineering graduates registration before professional boards. Biomedical engineering has not been listed by the government as an independent engineering discipline, preventing BME graduates registration as professional engineers in their field of expertise. To overcome this situation, the Northeastern National University UNNE developed an undergraduate BME option, which includes specific elective courses for electronics engineering students, allowing them a professional practice after graduation.
Bayesian Inference Based Learning Automaton Scheme in Fuzzy Environments

Learning automaton (LA), a powerful tool in reinforcement learning, is of crucial importance for its adaptivity in uncertain environments and its applicability in various engineering ﬁelds. In particular, the LA is a decision maker that adaptively explores the optimal action that maximizes the re-wards among all possible choices by interacting with the environment. Great eﬀorts have been made to improve the performance of LA in the P-model environments which provide only two types of feedback: reward and penalty. However, in many practical scenarios, the feedback from the environment is fuzzy rather than two-folded. This paper studies the LA in fuzzy environments, where the environment can conduct mediocre signals apart from crisp positive or negative ones. A novel Bayesian Inference based LA that is capable of functioning in fuzzy environments is proposed, which we name after BIFLA to emphasize its utility in fuzzy environments. The Bayesian inference is utilized to model the environments response behavior corresponding to each action, collaborating with the Kullback-Leibler divergence in achieving the adaptive decision-making and learning of LA. The BIFLA scheme is proved to be (cid:15) -optimal and is evaluated to be superior to established LA frameworks by comprehensive experiments.
HOW CAN MNCS OVERCOME LIABILITY OF FOREIGNESS? LOCALIZATION AS A MODERATOR OF THE RELATION BETWEN LOF AND PERFORMANCE

Foreign subsidiaries of multinational enterprises face numerous challenges stemming from their lack of familiarity with local languages, cultures, legal/policy frameworks and embedded customs in the host country. As such, MNEs wishing to expand globally strategize on how to effectively curb and manage the Liability of Foreignness (LOF) – that is, the tangible and intangible costs incurred on foreign subsidiaries that place them at a disadvantage compared to domestic firms. The literature on LOF confirms the negative impact of LOF on foreign subsidiary performance, but few address how to successfully overcome these liabilities. This study aims to further our understanding on foreign market entry by exploring the roles of LOF and localization as determinants of foreign subsidiary performance. Using a sample of 173 Korean companies in 34 countries, we empirically analyze LOF variables (cultural distance, local competition) and localization variables (market experience, hiring of local managers) to confirm their effects on subsidiary performance and corroborate the interplay between these variables. While cultural distance and local competition negatively affect subsidiary performance, our findings show that cultural distance can be bridged with market experience while hiring of local managers allows subsidiaries to more effectively compete against domestic rivals. 3 1 st Author, Department of Management, Dae Jeon University, Dea-Jeon, South Korea (E-mail: bgkim@dju.kr) 4 Corresponding Author, Korea University Business School, Seoul, South Korea (E-mail: jin4sky@korea.ac.kr)

Restrictive eating is common and associated with negative psychological outcomes across the life span and eating disorder (ED) severity levels. Little is known about functional processes that maintain restriction, especially outside of narrow diagnostic categories (e.g., anorexia nervosa). Here, we extend research on operant four-function models (identifying automatic negative, automatic positive, social negative, and social positive reinforcement functions) that have previously been applied to nonsuicidal self-injury (NSSI), binge eating, and purging to restricting. We assessed restrictive eating functions in three samples: clinically heterogeneous adolescents (Study 1: N = 457), transdiagnostic adults (Study 2: N = 145), and adults with acute or recently weight-restored anorexia nervosa (Study 3: N = 45). Study 1 indicated the four-function model was a good fit for restricting (root mean square error of approximation [RMSEA] = .06, Tucker-Lewis index [TLI] = .88). This factor structure replicated in Study 2 (comparative fit index [CFI] = .97, RMSEA = .07, TLI = .97, standardized root mean square residual [SRMR] = .09). Unlike NSSI, binge eating, and purging, which have been found to primarily serve automatic negative reinforcement functions, all three present studies found automatic positive reinforcement was most highly endorsed (by up to 85% of participants). In Studies 1 and 3, automatic functions were associated with poorer emotion regulation (ps , .05). In Study 1, social functions were associated with less social support (ps , .001). Across studies, automatic functions were associated with greater restriction ps , . 05). Functions varied slightly by ED diagnosis. Across ED presentation, severity, and developmental stage, restrictive eating may be largely maintained by automatic positive reinforcement, with some variability across presentations. Continued examination of restrictive eating functions will establish processes that maintain restriction, allowing more precise treatment targeting for these problematic behaviors.
Fiber Bragg-grating true time-delay systems: discrete-grating array 3-b delay lines and chirped-grating 6-b delay lines

We describe wavelength-addressed 3- and 6-b fiber-optic true time-delay (TTD) lines implemented using ultraviolet-inscribed Bragg gratings. The 3-b delay line is fabricated from an array of discrete- and uniform-period Bragg gratings, and a minimum time delay of 9.09 ps is selectable, making it suitable for phased-array antenna (PAA) beamforming control at RF frequencies of up to about 3 GHz with 10/spl deg/ phase resolution. The 6-b delay line is fabricated using a chirped-period Bragg grating, and is suitable for beamforming control at RF frequencies of up to /spl sim/48 GHz, with 10/spl deg/ phase resolution.
School of Accounting Seminar Series Semester 1, 2016 Clients in the Spotlight: Media Coverage and Audit Pricing

We examine the implications of media coverage on audit pricing. We propose two alternative explanations for the direction of the relation between a client’s media coverage and audit fees. Under the business risk view, media coverage can increase the auditor’s litigation risk and reputation risk ex ante, leading to higher audit fees. Under the corporate governance view, the media’s disciplining effect on firms can pressure clients to improve their financial reporting in the first place, resulting in lower inherent or control risk and lower audit fees. Our results support the business risk view. We find that media coverage is positively associated with audit fees, and this relation is stronger for clients that have higher litigation risk and that expose the auditor to greater reputational damage. We conduct a path analysis which suggests that auditors charge a media-related risk premium but also increase their audit effort to mitigate the potential risk. Our study contributes to the auditing literature by identifying media coverage as a distinct source of auditors’ business risk.
Waveguide antenna feed for the Square Kilometre Array

The aim of this thesis is to investigate the suitability of TEM (Transverse Electromagnetic) horn antennas for use as feed structures for the Square Kilometre Array (SKA) radio telescope, in particular with regard to the roundness of the radiation pattern. A literature study shows that existing TEM horn designs do not yield a round radiation pattern over a wide bandwidth and that an alternative is required. The Method of Moments (MoM) is a computational electromagnetic (CEM) technique typically used in the analysis of TEM horn antennas. An in-house MoM solver is successfully developed to analyse such antennas and is able to calculate the current density on the surface of a conductor, as well as the farfield patterns of an antenna. A modification to an exponential TEM horn antenna is proposed and simulations show the modification is successful in yielding a round radiation pattern over a wide bandwidth. The modified exponential TEM horn has a convex triangular arc at the end of each antenna plate and is constructed for measurement. Due to limited construction capabilities, the measurements deviate slightly from the simulated results but still indicate the potential of the structure to yield a round radiation pattern over a wide bandwidth.
SENSOR TECHNOLOGY IN THE NETHERLANDS: COLLABORATING TO TURN KNOWLEDGE INTO INNOVATION?

The Netherlands holds a strong position in fundamental sensor technology research, but this is not obviously translated into an internationally competitive sensor industry. In this paper we investigate whether sensor technology firms collaborate with external organizations, especially those related to public R&D. This would provide insight into the nature of the problems of knowledge transfer between organizations in the sensor technology industry, and enables us to provide policy recommendations regarding the collaboration and links between public and private R&D in this industry.
Aero-propulsive modelling for climb and descent trajectory prediction of transport aircraft using genetic algorithms

Abstract In this study, a new aero-propulsive model (APM) was derived from the flight manual data of a transport aircraft using Genetic Algorithms (GAs) to perform accurate trajectory predictions. This new GA-based APM provided several improvements to the existing models. The use of GAs enhanced the accuracy of both propulsive and aerodynamic modelling. The effect of compressible drag rise above the critical Mach number, which was not included in previous models, was considered along with the effects of compressibility and profile camber in the aerodynamic model. Consideration of the thrust dependency with respect to Mach number and the altitude in the propulsive model expression was observed to be a more practical approach. The proposed GA model successfully predicted the trajectory for the descent phase, as well, which was not possible in previous models. Close agreement was observed when comparing the time to climb and time to descent values obtained from the model with the flight manual data.
Elasto-Plastic Dynamic Finite Element Analysis of an Earth-Rockfill Dam

The Pastor-Zienkiewicz-Chan model based on the generalized plasticity theory can simulate the stress-strain relationship of soils quite well. Based on the triaxial tests of the filling materials of an earth-rockfill dam, model parameters were obtained through fittings of model and test data. The fitting curves showed that the generalized plasticity model is capable of simulating the mechanical behaviors of rockfill materials. The model was then implemented into a finite element code to carry out 3-dimensional static and dynamic analyses of the earth-rockfill dam. Permanent displacement of the dam was gained and discussed. The results show that the generalized plasticity model can give a good description of dynamic response characteristics of earth-rockfill dams.
Synthesis, Characterization, and Dye Removal of ZnCl2-Modified Biochar Derived from Pulp and Paper Sludge

In this study, pulp sludge-derived biochar synthesized through modification with ZnCl2 under multistep pyrolysis conditions was investigated for the effective removal of methylene blue (MB) from aqueous solution. Results showed that when the Zn2PT350-700 dosage was 10 mg, the largest adsorption amount of MB was 590.20 mg/g within 24 h under pH = 8. Kinetics and thermodynamics revealed that the adsorption process of MB can be described by the Freundlich isotherm model and the pseudo-second-order kinetic model, which means that multilayer sorption occurred on the heterogeneous surface of Zn2PT350-700. The analysis of the adsorption mechanism showed that electrostatic attraction between the deprotonated functional groups and MB+, cation exchange, and π-electron interaction played a major role in MB adsorption, followed by physical adsorption. After six cycles of desorption–adsorption, Zn2PT350-700 still maintained good adsorption performance. All results demonstrated that Zn2PT350-700 could perform as promising adsorbents for efficient MB removal from wastewater. Using biochar from paper and pulp sludge for wastewater remediation is an ingenious method, which can reduce the environmental and health risks related to industrial waste disposal, while providing remediation of water contaminated with industrial dye effluents.
