Internal Capital Markets and Firm-Level Compensation Incentives for Division Managers

Do multi-divisional firms structure compensation contracts for division managers to mitigate information and incentive problems in their internal capital markets? Using Compustat Segment financial data and compensation data from a proprietary survey, I find evidence that compensation and investment incentives are substitutes: firms providing a stronger link to firm performance in incentive compensation for division managers also provide weaker investment incentives through the capital budgeting process. Specifically, as the proportion of incentive pay for division managers that is based on firm performance increases, division investment is less responsive to division profitability. While these findings may be consistent with other explanations, they are generally consistent with a model of influence activities by division managers and the implied relative weights placed on imperfect, objective signals (i.e. accounting measures) versus distortable, subjective signals (i.e. manager recommendations) in inter-divisional capital allocation decisions. *I wish to thank Stan Baiman, Severin Borenstein, Brian Hall, Charlie Himmelberg, Bob Holthausen, Dan Levinthal, Maggie McMillan, Ron Miller, Andy Newman, Felix Oberholzer-Gee, Scott Stern, Louis Thomas and Joel Waldfogel for their comments and suggestions and Raffi Indjejikian, Dave Larcker and Abbie Smith for access to the compensation data.

Coronary artery Calcium predicts Cardiovascular events in participants with a low lifetime risk of Cardiovascular disease: The Multi-Ethnic Study of Atherosclerosis (MESA).

AIMS
Patients with a low lifetime risk of coronary heart disease (CHD) are not completely free of events over 10 years. We evaluated predictors for CHD among "low lifetime risk" participants in the population-based Multi-Ethnic Study of Atherosclerosis (MESA).


METHODS
MESA enrolled 6814 men and women aged 45-84 years who were free of baseline cardiovascular disease. Using established criteria of non-diabetic, non-smokers with total cholesterol ≤ 200 mg/dL, systolic BP ≤ 139 mmHg, and diastolic BP ≤ 89 mmHg at baseline, we identified 1391 participants with a low lifetime risk for cardiovascular disease. Baseline covariates were age, gender, ethnicity, HDL-C, C-reactive protein, family history of CHD, carotid intima-media thickness and coronary artery calcium (CAC). We calculated event rates and the number needed to scan (NNS) to identify one participant with CAC>0 and > 100.


RESULTS
Over 10.4 years median follow-up, there were 33 events (2.4%) in participants with low lifetime risk. There were 479 participants (34%) with CAC>0 including 183 (13%) with CAC>100. CAC was present in 25 (76%) participants who experienced an event. In multivariable analyses, only CAC>100 remained predictive of CHD (HR 4.6; 95% CI: 1.6-13.6; p = 0.005). The event rates for CAC = 0, CAC>0 and CAC>100 were 0.9/1,000, 5.7/1,000, and 11.0/1000 person-years, respectively. The NNS to identify one participant with CAC>0 and > 100 were 3 and 7.6, respectively.


CONCLUSIONS
While 10-year event rates were low in those with low lifetime risk, CAC was the strongest predictor of incident CHD. Identification of individuals with CAC = 0 and CAC>100 carries significant potential therapeutic implications.
Foraminiferal Mg/Ca increase in the Caribbean during the Pliocene: Western Atlantic Warm Pool formation, salinity influence, or diagenetic overprint?: CARIBBEAN FORAMINIFERAL Mg/Ca

[1] We constructed a high-resolution Mg/Ca record on the planktonic foraminifer Globigerinoides sacculifer in order to explore the change in sea surface temperature (SST) due to the shoaling of the Isthmus of Panama as well as the impact of secondary factors like diagenesis and large salinity fluctuations. The study covers the latest Miocene and the early Pliocene (5.6–3.9 Ma) and was combined with dO to isolate changes in sea surface salinity (SSS). Before 4.5 Ma, SSTMg/Ca and SSS show moderate fluctuations, indicating a free exchange of surface ocean water masses between the Pacific and the Atlantic. The increase in dO after 4.5 Ma represents increasing salinities in the Caribbean due to the G Geochemistry Geophysics Geosystems
Principles of Health Interoperability

This chapter sets out some of the core problems and opportunities facing the digital healthcare sector. Healthcare is all about communication. Large investments in digital health have failed to live up to expectations, partly due to poor interoperability. Patient centered care requires a new approach, organized primarily for patient benefi t, not just for provider organizations. What matters most is the point of care, which is inevitably complex. Many lessons can be learnt from past experience, successes and failures.
Influence of landmark-based navigation instructions on user attention in indoor smart spaces

Using landmark-based navigation instructions is widely considered to be the most effective strategy for presenting navigation instructions. Among other things, landmark-based instructions can reduce the user's cognitive load, increase confidence in navigation decisions and reduce the number of navigational errors. Their main disadvantage is that the user typically focuses considerable amount of attention on searching for landmark points, which easily results in poor awareness of the user's surroundings. In indoor spaces, this implies that landmark-based instructions can reduce the attention the user pays on advertisements and commercial displays, thus rendering the assistance commercially inviable. To better understand how landmark-based instructions influence the user's awareness of her surroundings, we conducted a user study with $20$ participants in a large national supermarket that investigated how the attention the user pays on her surroundings varies across two types of landmark-based instructions that vary in terms of their visual demand. The results indicate that an increase in the visual demand of landmark-based instructions does not necessarily improve the participant's recall of their surrounding environment and that this increase can cause a decrease in navigation efficiency. The results also indicate that participants generally pay little attention to their surroundings and are more likely to rationalize than to actually remember much from their surroundings. Implications of the findings on navigation assistants are discussed.
Studies of the microstructure and properties of dense ceramic coatings produced by high-velocity oxygen-fuel combustion spraying

High-velocity oxygen-fuel (HVOF) spraying stands out among the various processes to improve metal and ceramic coating density and surface characteristics. This paper explores microstructure development, coating characterization and properties of HVOF sprayed alumina coatings and compares these with those produced using the conventional air plasma spray process. We report on the characterization of these coatings using small-angle neutron scattering (SANS) and X-ray computed microtomography (XMT) to explain the behavior observed for the two coating systems. Microstructure information on porosity, void orientation distribution, void mean opening dimensions and internal surface areas have been obtained using SANS. XMT (X-ray synchrotron microtomography) has been used to nondestructively image the microstructural features in 3D at a 2.7m spatial resolution over a 2–3 mm field of view. 3D medial axis analysis has been used for the quantitative analysis of the coarse void space in order to obtain information on the porosity, specific surface area, pore connectivity and size distribution of the larger voids in the coatings. The results reveal different pore morphologies for the two spray processes. While only globular pores are imaged in the plasma sprayed coatings due to the spatial resolution limit, highly layered porosity is imaged in the HVOF coating. When the quantitative SANS and XMT information are combined, the different thermal and mechanical properties of the two different coating types can be explained in terms of their distinctly different void microstructures. © 2003 Elsevier B.V.

Three-Port DC–DC Converter for Stand-Alone Photovoltaic Systems

System efficiency and cost effectiveness are of critical importance for photovoltaic (PV) systems. This paper addresses the two issues by developing a novel three-port dc-dc converter for stand-alone PV systems, based on an improved Flyback-Forward topology. It provides a compact single-unit solution with a combined feature of optimized maximum power point tracking (MPPT), high step-up ratio, galvanic isolation, and multiple operating modes for domestic and aerospace applications. A theoretical analysis is conducted to analyze the operating modes followed by simulation and experimental work. This paper is focused on a comprehensive modulation strategy utilizing both PWM and phase-shifted control that satisfies the requirement of PV power systems to achieve MPPT and output voltage regulation. A 250-W converter was designed and prototyped to provide experimental verification in term of system integration and high conversion efficiency.
Direct torque control of four-switch brushless DC Motor with non-sinusoidal back-EMF

This paper presents a direct torque control (DTC) technique for brushless DC (BLDC) motors with non-sinusoidal back-EMF using four-switch inverter in the constant torque region. This approach introduces a two-phase conduction mode as opposed to the conventional three-phase DTC drives. Unlike conventional six-step PWM current and voltage control schemes, by properly selecting the inverter voltage space vectors of the two-phase conduction mode from a simple look-up table at a predefined sampling time, the desired quasi-square wave current is obtained. Therefore, a much faster torque response is achieved compared to conventional PWM current and especially voltage control schemes. In addition, for effective torque control in two phase conduction mode, a novel switching pattern incorporating with the voltage vector look-up table is designed and implemented for four-switch inverter to produce the desired torque characteristics. Furthermore, to eliminate the low-frequency torque oscillations caused by the non-ideal trapezoidal shape of the actual back-EMF waveform of the BLDC motor, pre-stored back-EMF constant versus position lookup tables are designed and used in the torque estimation. As a result, it is possible to achieve two-phase conduction DTC of a BLDC motor drive using four-switch inverter with faster torque response due to the fact that the voltage space vectors are directly controlled. Therefore, the direct torque controlled four-switch three-phase BLDC motor drive could be a good alternative to the conventional six-switch counterpart with respect to low cost and high performance. A theoretical concept is developed and the validity and effectiveness of the proposed two phase conduction four- switch DTC scheme are verified through the simulations and experimental results.
Manifold Mixup : Learning Better Representations by Interpolating Hidden States

Deep networks often perform well on the data distribution on which they are trained, yet give incorrect (and often very confident) answers when evaluated on points from off of the training distribution. This is exemplified by the adversarial examples phenomenon but can also be seen in terms of model generalization and domain shift. Ideally, a model would assign lower confidence to points unlike those from the training distribution. We propose a regularizer which addresses this issue by training with interpolated hidden states and encouraging the classifier to be less confident at these points. Because the hidden states are learned, this has an important effect of encouraging the hidden states for a class to be concentrated in such a way so that interpolations within the same class or between two different classes do not intersect with the real data points from other classes. This has a major advantage in that it avoids the underfitting which can result from interpolating in the input space. We prove that the exact condition for this problem of underfitting to be avoided by Manifold Mixup is that the dimensionality of the hidden states exceeds the number of classes, which is often the case in practice. Additionally, this concentration can be seen as making the features in earlier layers more discriminative. We show that despite requiring no significant additional computation, Manifold Mixup achieves large improvements over strong baselines in supervised learning, robustness to single-step adversarial attacks, semi-supervised learning, and Negative Log-Likelihood on held out samples. * Equal contribution. †Work done while author was visiting Montreal Institute for Learning Algorithms.

Dynamic Identification of Dynamic Stochastic General Equilibrium Models

THIS SUPPLEMENTARY DOCUMENT contains additional examples. Matlab code for constructing the ΔS(θ) and ΔNS(θ) matrices proposed in Komunjer and Ng (2011) is also provided to show that while the expression appears complex, the computation is simple. Once the minimal representation is obtained, ΔΛ(θ) and Δ NS(θ) can be computed using numerical differentiation. The ΔT (θ) and ΔNS T (θ) only require specification of nX , while Δ S U(θ) only requires nε. Section S.1 uses the model of An and Schorfheide (2007) to study the implications of (i) adding ct to the observables, and (ii) dropping variables to remove singularity. Section S.2 analyzes the model in Smets and Wouters (2007). It is shown that putting the model into minimal state space representation reveals features about the model that are not otherwise transparent. In particular, the parameters in the policy rule, output, and potential output equations are not independent. Section S.3 analyzes the model of Christiano, Eichenbaum, and Evans (2005). Section S.4 considers the model of Cicco, Pancrazi, and Uribe (2010) that is identifiable without further restrictions. Matlab code for computing the Δ(θ0) matrix is given in Section S.5.
National Embeddedness and Calculative HRM in US Subsidiaries in Europe and Australia

This article presents a study of the degree to which national institutional settings impact on the application of management practices in foreign subsidiaries of multinational companies. Applying the national business systems approach our study centres on the use of calculative human resource management (HRM) practices by subsidiaries of US multinational companies in the UK, Ireland, Germany, Denmark/Norway and Australia, respectively, in comparison with these countries’ indigenous firms. The analysis indicates that while US subsidiaries adapt to the local setting in terms of applying calculative HRM practices, they also diverge from indigenous firm practices.

The relationship between job satisfaction and intention to leave current employment among registered nurses in a teaching hospital.

AIMS AND OBJECTIVES
To assess Malaysian nurses' perceived job satisfaction and to determine whether any association exists between job satisfaction and intention to leave current employment.


BACKGROUND
There is currently a shortage of qualified nurses, and healthcare organisations often face challenges in retaining trained nurses. Job satisfaction has been identified as a factor that influences nurse turnover. However, this has not been widely explored in Malaysia.


DESIGN
Cross-sectional survey.


METHODS
Registered nurses in a teaching hospital in Malaysia completed a self-administered questionnaire. Of the 150 questionnaires distributed, 141 were returned (response rate = 94%).


RESULTS
Overall, nurses had a moderate level of job satisfaction, with higher satisfaction for motivational factors. Significant effects were observed between job satisfaction and demographic variables. About 40% of the nurses intended to leave their current employment. Furthermore, age, work experience and nursing education had significant associations with intention to leave. Logistic regression analysis revealed that job satisfaction was a significant and independent predictor of nurses' intention to leave after controlling for demographic variables.


CONCLUSION
The results suggest that there is a significant association between job satisfaction and nurses' intention to leave their current employment. It adds to the existing literature on the relationship between nurses' job satisfaction and intention to leave.


RELEVANCE TO CLINICAL PRACTICE
Methods for enhancing nurses' job satisfaction are vital to promote the long-term retention of nurses within organisations. Attention must be paid to the needs of younger nurses, as they represent the majority of the nursing workforce and often have lower satisfaction and greater intention to leave than older nurses do. Strategies to nurture younger nurses, such as providing opportunities for further education, greater management decision-making capabilities and flexible working environment, are essential.
Banks ' Liability Structure and Mortgage Lending During the Financial Crisis

We examine the impact of banks’ exposure to market liquidity shocks through wholesale funding on their supply of credit during the financial crisis in the United States. We focus on mortgage lending to minimize the impact of confounding demand factors that could potentially be large when comparing banks’ overall lending across heterogeneous categories of credit. The disaggregated data on mortgage applications that we use allows us to study the time variations in banks’ decisions to grant mortgage loans, while controlling for bank, borrower, and regional characteristics. The wealth of data also allows us to carry out matching exercises that eliminate imbalances in observable applicant characteristics between wholesale and retail banks, as well as various other robustness tests. We find that banks that were more reliant on wholesale funding curtailed their credit significantly more than retail-funded banks during the crisis. The demand for mortgage credit, on the other hand, declined evenly across wholesale and retail banks. To understand the aggregate implications of our findings, we exploit the heterogeneity in mortgage funding across U.S. Metropolitan Statistical Areas (MSAs) and find that wholesale funding was a strong and significant predictor of a sharper decline in overall mortgage credit at the MSA level.

Archaeoastronomical Evidence for Wuism at the Hongshan Site of Niuheliang

Introduction The Neolithic Hongshan Culture flourished between 4500 and 3000 BCE in what is today northeastern China and Inner Mongolia (Figure 1). Village sites are found in the northern part of the region, while the two ceremonial sites of Dongshanzui and Niuheliang are located in the south, where villages are fewer (Guo 1995, Li 2003). The Hongshan inhabitants included agriculturalists who cultivated millet and pigs for subsistence, and accomplished artisans who carved finely crafted jades and made thin black-on-red pottery. Organized labor of a large number of workers is suggested by several impressive constructions, including an artificial hill containing three rings of marble-like stone, several high cairns with elaborate interiors and a 22 meter long building which contained fragments of life-sized statues. One fragment was a face with inset green jade eyes (Figure 2). A ranked society is implied by the burials, which include decorative jades made in specific, possibly iconographic, shapes. It has been argued previously that the sizes and locations of the mounded tombs imply at least three elite ranks (Nelson 1996).
FACTORS ASSOCIATED WITH TOBACCO SMOKING AMONG MALE ADOLESCENTS: THE ROLE OF PSYCHOLOGIC, BEHAVIORAL, AND DEMOGRAPHIC RISK FACTORS

Background: Tobacco smoking among adolescents has been a concern for researchers and health organizations in recent years. However, predisposing factors to smoking initiation among Iranian adolescents are not well recognized. Objectives: This study aimed to determine the prevalence of tobacco smoking and to investigate the role of psychologic, behavioral, and demographic risk factors in adolescents' smoking status. Patients and Methods: This cross-sectional study was performed on 810 male adolescents recruited through cluster random sampling method in Hamadan in 2014. The participants received a self-administered questionnaire that contained questions about tobacco smoking behavior and demographic, behavioral, and psychologic variables. Data were analyzed by SPSS16 through independent-samples t test, Chi square, and logistic regression. Results: A total of 139 persons (17.1%) were tobacco smoker and the mean (SD) age at smoking initiation was 13.7 (2.2) years. Sense of need, decreasing stress, having a smoker friend, and inability to reject smoking suggestion were common reasons associated with tobacco smoking (P < 0.05). In addition, statistically significant differences between tobacco smokers and nonsmokers were found in the age, grade, mother's job, and education (P < 0.05). In comparison to non-smokers, tobacco smokers evaluated a typical smoker as less immature, more popular, more attractive, more self-confident, more independent, and less selfish person (P < 0.05). Conclusions: The results showed that the effect of several psychosocial, behavioral, and demographic risk factors on adolescents' smoking status. Thus, design and implementation of interventions based on the results of the present study may be effective in preventing tobacco smoking among adolescents.
