Corporate Performance, Corporate Takeovers, and Management Turnover

This paper examines the hypothesis that an important role of corporate takeovers is to discipline the top managers of poorly performing target firms. The authors document that the turnover rate for the top manager of target firms in tender offer-takeovers significantly increases following completion of the takeover and that prior to the takeover these firms were significantly under-performing other firms in their industry as well as other target firms which had no post-takeover change in the top executive. We interpret the results to indicate that the takeover market plays an important role in controlling the nonvalue maximizing behavior of top corporate managers.

A Practical Method for Determining the Corten-Dolan Exponent and Its Application to Fatigue Life Prediction

Abstract Based on the derivation and calculation of the Corten-Dolan exponent d, a practical method of determining its value is proposed. This exponent depends not only upon the materials, but also upon the load spectrums. Therefore its value is obtained by a function which decreases with increasing stress amplitude. This exponent was investigated through analysis of fatigue damage evolution to determine its parameters. The proposed method has been effectively proved by experimental data from literature. Utilization of the modified Corten-Dolan's model significantly improves its life prediction capability when compared to the conventional model where that exponent was assumed to be constant.
Effect of Learning Strategy and Cognitive Styles on Students' Learning Outcomes of Civic Education and Social Skills

The core of civic education both in concept and implementation is the students’ change in relation to learning outcome which covers cognitive, effective, and psychomotor domains. This can be reached when learning is organized, carried out, and managed effectively by teachers. This study describes the relationship between learning strategy of two stays two stray and direct instruction which is connected with cognitive styles of field independent and field dependent to the students’ comprehension and social skills. This study used a quasi-factorial experimental design of 2 x 2. The subject was Grade XI students of the State Senior High Schools in Palu. The subjects were divided into two groups consisting of the students taught using cooperative learning strategy of two stays two stray and the students taught using direct instruction. The study shows that 1) there is a significant difference of comprehension on the civic education of the students taught using cooperative learning strategy of two stay two stray and those taught using direct instruction, 2) there is no significant difference in comprehension between the students with cognitive style of field independent and the ones with cognitive style of field dependent, 3) there is no interaction between the learning strategy and the students’ cognitive styles.

Out‐of‐pocket costs and burden among rural breast cancer survivors

Little is known about out‐of‐pocket (OOP) costs incurred for medical and health needs by rural breast cancer survivors and what factors may be associated with higher OOP costs and the associated economic burden. Data were examined for 432 survivors participating in the Rural Breast Cancer Survivor Intervention trial. OOP costs were collected using the Work and Finances Inventory survey at baseline and four assessments every 3 months. Mean and median OOP costs and burden (percent of monthly income spent on OOP costs) were reported and factors associated with OOP costs and burden identified with generalized linear models fitted with over‐dispersed gamma distributions and logarithmic links (OOP costs) and with beta distributions with logit link (OOP burden). OOP costs per month since the end of treatment were on average $232.7 (median $95.6), declined at the next assessment point to $186.5 (median $89.1), and thereafter remained at that level. Mean OOP burden was 9% at baseline and between 7% and 8% at the next assessments. Factors suggestive of contributing to higher OOP costs and OOP burden were the following: younger age, lower income, time in survivorship from diagnosis, and use of supportive services. OOP costs burden rural breast cancer survivors, particularly those who are younger and low income. Research should investigate the impact of OOP costs and interventions to reduce economic burden.
Low-dose-rate radiation exposure leads to testicular damage with decreases in DNMT1 and HDAC1 in the murine testis

This study examined the effects of continuous low-dose-rate radiation exposure (3.49 mGy/h) of gamma rays on mice testicles. C57BL/6 mice were divided into sham and radiation groups (n = 8 each), and were exposed to either sham irradiation or 2 Gy for 21 days, 0.2 Gy for 2 days, or 0.02 Gy for 6 h of low-dose-rate irradiation. Testicular weight, seminiferous tubular diameter, and seminiferous epithelial depth were significantly decreased in the mice irradiated with 2 Gy at 1 and 9 days after exposure. Moreover, the low-dose-rate radiation exposure induced an increase in malondialdehyde levels, and a decrease in superoxide dismutase activity in the testis of mice irradiated with 2 Gy at 1 and 9 days after exposure. The sperm count and motility in the epididymis also decreased in mice irradiated with 2 Gy at 1 and 9 days after exposure, whereas there was no significant effect on the proportion of abnormal sperm. The expressions of DNA methlytransferases-1 and histone deacetylases 1 in testes irradiated with 2 Gy were significantly decreased compared with the sham group. In conclusion, the damage exerted on the testes and epididymis largely depended on the total dose of low-dose-rate radiation.
Very extended E-8 and A(8) at low levels, gravity and supergravity

We define a level for a large class of Lorentzian Kac–Moody algebras. Using this we find the representation content of very extended AD−3 and E8 (i.e., E11) at low levels in terms of AD−1 and A10 representations, respectively. The results are consistent with the conjectured very extended A8 and E11 symmetries of gravity and maximal supergravity theories given respectively in preprints hep-th/0104081 and hep-th/0107209. We explain how these results provided further evidence for these conjectures.
A Testbed to Evaluate the FIWARE-Based IoT Platform in the Domain of Precision Agriculture

Wireless sensor networks (WSNs) represent one of the most promising technologies for precision farming. Over the next few years, a significant increase in the use of such systems on commercial farms is expected. WSNs present a number of problems, regarding scalability, interoperability, communications, connectivity with databases and data processing. Different Internet of Things middleware is appearing to overcome these challenges. This paper checks whether one of these middleware, FIWARE, is suitable for the development of agricultural applications. To the authors’ knowledge, there are no works that show how to use FIWARE in precision agriculture and study its appropriateness, its scalability and its efficiency for this kind of applications. To do this, a testbed has been designed and implemented to simulate different deployments and load conditions. The testbed is a typical FIWARE application, complete, yet simple and comprehensible enough to show the main features and components of FIWARE, as well as the complexity of using this technology. Although the testbed has been deployed in a laboratory environment, its design is based on the analysis of an Internet of Things use case scenario in the domain of precision agriculture.
Effect of group health behaviour change coaching on psychosocial constructs associated with physical activity among university employees

Lifestyle behaviours are a contributing factor in approximately 80% of chronic diseases, making them a primary target for employee wellness programmes (EWPs). To effectively change health behaviours, EWPs should implement evidence-based strategies. One strategy is health behaviour change coaching, which is often delivered in a one-on-one format. While limited research exists, group health behaviour change coaching (group coaching) has potential to be an efficient alternative, impacting more people. The purpose of this study was to determine whether group health coaching improved psychological constructs related to physical activity and physical fitness among university employees in an EWP. Employees (n = 100) were randomly selected from a pool of volunteers who registered for the EWP, were overweight/obese, and at risk for cardiovascular disease. The intervention consisted of three group coaching sessions based on the Transtheoretical Model and Self-Determination Theory. Paired t-tests compared pre/post-measures of psychological constructs related to physical activity and physical fitness. Additionally, multivariate regression analysis with post-coaching self-efficacy as the dependent variable was performed. Overall, 84 participants (83% female, average BMI = 31.2) completed the intervention, attending an average of 2.26 sessions. Stages of change, seven processes of change, self-efficacy, perceived competence, and the health care climate score improved. Attending group coaching sessions predicted post-test self-efficacy. All but one measure of physical fitness improved. Group coaching can be effective in improving physical fitness and psychological constructs related to physical activity behaviour. In programmes with limited funds, group coaching has potential to be an important EWP component to support health behaviour change.
Entry Restrictions, Industry Evolution, And Dynamic Efficiency: Evidence from Commercial Banking

This paper shows that bank performance improves significantly after restrictions on bank expansion are lifted. We find that operating costs and loan losses decrease sharply after states permit statewide branching and, to a lesser extent, after states allow interstate banking. The improvements following branching deregulation appear to occur because better banks grow at the expense of their less-efficient rivals. By retarding the "natural"evolution of the industry, branching restrictions reduce the performance of the average banking asset. We also find that most of the reduction in banks' costs are passed along to bank borrowers in the form of lower loan rates.
Progressive Shape-Distribution-Encoder for 3D Shape Retrieval

In this paper, we propose a deep shape descriptor by learning the shape distributions at different diffusion time via a progressive deep shape-distribution-encoder. First, we develop a shape distribution representation with the kernel density estimator to characterize the intrinsic geometrical structure of the shape. Then, we propose to learn discriminative shape features through a progressive shape-distribution-encoder. Specially, the progressive shape-distribution-encoder aims at modeling the complex non-linear transform of the estimated shape distributions between consecutive diffusion time. Furthermore, in order to characterize the intrinsic structure of the shape more efficiently, we stack multiple proposed progressive shape-distribution-encoders to form a neural network structure. Finally, we concatenated all neurons in the hidden layers of the progressive shape-distribution-encoder network to form a discriminative shape descriptor for retrieval. The proposed method is evaluated on three benchmark 3D shape datasets %with large geometric variations, i.e., McGill, SHREC'10 ShapeGoogle and SHREC'14 Human datasets, and the experimental results demonstrate the superiority of our method to the existing approaches.
Depressive comorbidity in preschool anxiety disorder

Background The threshold for clinical relevance of preschool anxiety has recently come under increasing scrutiny in view of large variations in prevalence estimates. We studied the impact of presence/absence of additional depressive comorbidity (symptoms and/or diagnosis) on preschoolers with anxiety disorders in relation to clinical phenomenology, family, and peer problems compared to healthy controls. Method A population of 1738 preschoolers were screened and oversampled for internalizing symptoms from community sites, yielding a sample of 236 children. Results Using a multi-informant approach (mother, father, teacher, child), we found evidence that children with anxiety disorders and depressive comorbidity display a greater internalizing symptom-load, more peer problems and live in families with more psychosocial impairment (poor family functioning, family adversity, maternal mental health problems). The pure anxiety group was merely dissociable from controls with regard to internalizing symptoms and family adversity. Conclusion The presence of depressive comorbidity in anxiety disorders may mark the transition to a more detrimental and impairing disorder at preschool age.

Gaussian Limts for Random Geometric Measures

Given $n$ independent random marked $d$-vectors $X_i$ with a common density, define the measure $\nu_n = \sum_i \xi_i $, where $\xi_i$ is a measure (not necessarily a point measure) determined by the (suitably rescaled) set of points near $X_i$. Technically, this means here that $\xi_i$ stabilizes with a suitable power-law decay of the tail of the radius of stabilization. For bounded test functions $f$ on $R^d$, we give a central limit theorem for $\nu_n(f)$, and deduce weak convergence of $\nu_n(\cdot)$, suitably scaled and centred, to a Gaussian field acting on bounded test functions. The general result is illustrated with applications to measures associated with germ-grain models, random and cooperative sequential adsorption, Voronoi tessellation and $k$-nearest neighbours graph.
MATHEMATICAL COMMUNICATION ABILITY AND SELF CONFIDENCE Experiment with Eleventh Grade Students Using Scientific Approach

This study is a pre test-post test experiment with control group design having a goal to analyze the role of scientific approach on students’ mathematical communication ability (MCA) and self confidence (SC). The study involves 46 eleventh grade Vocational School students, a mathematical communication test, a mathematical self confidence scale (MSC), and a perception on scientific approach scale. The study found that on MCA and its Normalized Gain (N ), students getting treatment with scientific approach attained better grades than the grades of students taught by conventional teaching, but both student’s grades were still at low-medium level. On MSC, there was no different grades between students on both teaching approaches, and those grades were at medium level. The other findings, there is no association between MCA and MSC, and students performed high perception toward scientific approach.
Validated HPTLC Method for Quantification of Luteolin and Apigenin in Premna mucronata Roxb., Verbenaceae

A simple, rapid, and precise high-performance thin-layer chromatographic method was developed for quantitative estimation of luteolin and apigenin in Premna mucronata Roxb. , family Verbenaceae. Separation was performed on silica gel 60 F254 HPTLC plates using toluene : ethyl acetate : formic acid (6 : 4 : 0.3) as mobile phase for elution of markers from extract. The determination was carried out in fluorescence mode using densitometric absorbance-reflection mode at 366 nm for both luteolin and apigenin. The methanolic extract of Premna mucronata was found to contain 10.2 mg/g % luteolin and 0.165 mg/g % of apigenin. The method was validated in terms of linearity, LOD and LOQ, accuracy, precision, and specificity. The calibration curve was found to be linear between 200 and 1000 ng/band for luteolin and 50 and 250 ng/band for apigenin. For luteolin and apigenin, the limit of detection was found to be 42.6 ng/band and 7.97 ng/band while the limit of quantitation was found to be 129.08 ng/band and 24.155 ng/band, respectively. This developed validated method is capable of quantifying and resolving luteolin and apigenin and can be applicable for routine analysis of extract and plant as a whole.
Financial Stability and Monetary Policy: How Closely Interlinked?

The recent financial crisis has again raised the question to what extent price-stability-oriented monetary policy frameworks should take into account financial stability objectives. In this paper I argue that the answer will depend on three questions: (i) how effective is macroprudential policy in maintaining financial stability? (ii) what is the effect of monetary policy on risk taking and financial stability? and (iii) what is the risk of financial dominance, i.e., the risk that financial stability considerations undermine the credibility of the central bank’s price stability mandate? I review the theory and evidence and conclude that while the new macroprudential policy framework should be the main tool for maintaining financial stability, monetary policy authorities should also keep an eye on financial stability. This will allow the central bank to lean against the wind if necessary, while maintaining its primary focus on price stability over the medium term.
On maximizing the convergence rate for linear systems with input saturation

In this paper, we consider the problem of maximizing the convergence rate inside a given level set for both continuous-time and discrete-time systems with input saturation. We also provide simple methods for finding the largest ellipsoid of a given shape that can be made invariant with a saturated control. For the continuous-time case, the maximal convergence rate is achieved by a bang-bang type control with a simple switching scheme. Suboptimal convergence rate can be achieved with saturated high-gain linear feedback. For the discrete-time case, the maximal convergence rate is achieved by a coupled saturated linear feedback.
Cortical dopamine release during a behavioral response inhibition task

Dopamine (DA) dysregulation within fronto‐striatal circuitry may underlie impulsivity in alcohol and other substance use disorders. To date, no one has directly demonstrated DA release during a task requiring the control of impulsive behavior. The current study was conducted to determine whether a response inhibition task (stop signal task; SST) would elicit detectable extrastriatal DA release in healthy controls. We hypothesized that DA release would be detected in regions previously implicated in different aspects of inhibitory control. [18F]Fallypride (FAL) PET imaging was performed in nine healthy males (24.6 ± 4.1 y.o.) to assess changes in cortical DA during a SST relative to a baseline “Go” task. On separate days, subjects received one FAL scan during the SST, and one FAL scan during a “Go” control; task‐order was counter‐balanced across subjects. Parametric BPND images were generated and analyzed with SPM8. Voxel‐wise analysis indicated significant SST‐induced DA release in several cortical regions involved in inhibitory control, including the insula, cingulate cortex, orbitofrontal cortex, precuneus, and supplementary motor area. There was a significant positive correlation between stop signal reaction time and DA release in the left orbitofrontal cortex, right middle frontal gyrus, and right precentral gyrus. These data support the feasibility of using FAL PET to study DA release during response inhibition, enabling investigation of relationships between DA function and impulsive behavior.

Feasibility of a Short-Arm Centrifuge for Mouse Hypergravity Experiments

To elucidate the pure impact of microgravity on small mammals despite uncontrolled factors that exist in the International Space Station, it is necessary to construct a 1 g environment in space. The Japan Aerospace Exploration Agency has developed a novel mouse habitat cage unit that can be installed in the Cell Biology Experiment Facility in the Kibo module of the International Space Station. The Cell Biology Experiment Facility has a short-arm centrifuge to produce artificial 1 g gravity in space for mouse experiments. However, the gravitational gradient formed inside the rearing cage is larger when the radius of gyration is shorter; this may have some impact on mice. Accordingly, biological responses to hypergravity induced by a short-arm centrifuge were examined and compared with those induced by a long-arm centrifuge. Hypergravity induced a significant Fos expression in the central nervous system, a suppression of body mass growth, an acute and transient reduction in food intake, and impaired vestibulomotor coordination. There was no difference in these responses between mice raised in a short-arm centrifuge and those in a long-arm centrifuge. These results demonstrate the feasibility of using a short-arm centrifuge for mouse experiments.
