An investigation of pay ratio and board time commitment
Creators: name: Tang, Fujun
Publisher: name: No Publisher Supplied
Year: 2022

description: The dissertation examines the effect of pay ratio and the value of board time commitment. This first essay investigates the impact of pay ratio on employees and investors. I find that poorer employee productivity is associated with a higher pay ratio, whereas worse employee satisfaction is only associated with a higher industry-adjusted pay ratio. I also find that firms with higher pay ratio are more likely to receive higher shareholder Say on Pay voting dissent, and higher mutual fund voting dissent. The results are consistent after regressing on unexplained pay ratio and controlling for linguistic style, rule flexibility usage, local minimum wage, pay for performance sensitivity, and excessive CEO pay. Firms having a higher pay ratio are more likely to have lower sales, a lower firm return, and reduced CEO pay and pay ratio in the following year. The second essay examines how the ratio of CEO compensation to average employee compensation affects banks’ willingness to apply for the Troubled Asset Relief Program (TARP) capital, Treasury’s decision to approve the application, and participating banks’ pace to repay the funds during the financial crisis using the manually gathered data from eligible banks’ company fillings. Results show that banks with higher pay ratios are less likely to apply for the government aid and are more likely to pay back the funds faster. The Treasury is less likely to approve bank applicants with higher pay ratios. CEO turnovers during financial crisis are more likely to occur in banks with larger pay ratios. Evidence in this paper may shed light on the government’s potential future bailout policies. Different from most countries that have no statutory rule or law pertaining to when people should retire from their occupations, China State Council enforces compulsory retirement for all workers. The third essay exploits this mandatory retirement regulation as an exogenous source of variation in independent directors’ workload to isolate the time commitment to provide new empirical evidence on the value of independent directors’ time commitment in the boardroom. The empirical findings using difference in difference (DID) and research discontinuity (RD) designs show that retired independent directors are more physically and cognitively committed to their monitoring and advising roles, evidenced by more personal board attendances, less authorized representative attendances, and increased diligence level. We also find that more time committed by retired independent directors is associated with better executive pay for performance sensitivity, lower excess CEO pay, more investment spending, higher financial statement comparability, and higher annual stock return.

description: In a previous contribution, Phys. Rev. Lett 107, 230601 (2011), we have proposed a method to treat first order phase transitions at low temperatures. It describes arbitrary order parameter through an analytical expression $W$, which depends on few coefficients. Such coefficients can be calculated by simulating relatively small systems, hence with a low computational cost. The method determines the precise location of coexistence lines and arbitrary response functions (from proper derivatives of $W$). Here we exploit and extend the approach, discussing a more general condition for its validity. We show that in fact it works beyond the low $T$ limit, provided the first order phase transition is strong enough. Thus, $W$ can be used even to study athermal problems, as exemplified for a hard-core lattice gas. We furthermore demonstrate that other relevant thermodynamic quantities, as entropy and energy, are also obtained from $W$. To clarify some important mathematical features of the method, we analyze in details an analytically solvable problem. Finally, we discuss different representative models, namely, Potts, Bell-Lavis, and associating gas-lattice, illustrating the procedure broad applicability.

description: We investigate the magnetic interface states of graphene quantum dots that contain p-n junctions. Within a tight-binding approach, we consider rectangular quantum dots in the presence of a perpendicular magnetic field containing p-n, as well as p-n-p and n-p-n junctions. The results show the interplay between the edge states associated with the zigzag terminations of the sample and the snake states that arise at the p-n junction, due to the overlap between electron and hole states at the potential interface. Remarkable localized states are found at the crossing of the p-n junction with the zigzag edge having a dumb-bell shaped electron distribution. The results are presented as function of the junction parameters and the applied magnetic flux.

description: Bei der Entwicklung hochauflösender Lichtsysteme werden in den Phasen des Konzipierens und Entwerfens auf Grundlage verschiedenster Anforderungen erfolgsbestimmende Entscheidungen getroffen. Für die Entwicklung einfacher Lichtsysteme, die aus einer Lichtquelle und einem optischen Element zur Strahlformung oder -ablenkung aufgebaut sind, können die zu treffenden Entscheidungen noch gut beherrscht werden. Mit zunehmender Komplexität der Lichtsysteme, beispielsweise durch die Verwendung von Lichtmodulatoren und dem Einsatz mehrerer optischer Elemente, erfordert die Entscheidungsfindung ein methodisches Vorgehen, um unüberwindbaren Diskrepanz zwischen Entwicklungszielen und -ergebnissen zu vermeiden. Im Rahmen dieser Arbeit werden Methoden zum Konzipieren und Entwerfen hochauflösender Lichtsysteme erarbeitet und an einem Beispiel angewendet. Unter Berücksichtigung der Étendue als Erhaltungsgröße in optischen Systemen wird durch die logische Verknüpfung spezifischer Schritte ein planmäßiges und zielorientiertes Vorgehen zum Konzipieren bereitgestellt. Hierbei werden Technologien zur Lichtmodulation und -erzeugung, die räumliche Anordnung optischer Elemente für Systemarchitekturen und Strategien zur Beleuchtung des Lichtmodulators sowie dem auszuleuchtenden Bereich für die Anwendung spezifiziert. Im letzten Schritt wird ein Strahlenmodell als Grundlage für den nachfolgenden Entwurf erarbeitet. Das methodische Vorgehen zum Entwerfen erfolgt unter Berücksichtigung der sequentiellen und nicht-sequentiellen Strahlverfolgung. Durch Festlegen von Lichtquelleneigenschaften, Funktionsflächen und Randbedingungen wird der sequentielle Optikentwurf mithilfe von Entwurfszielen, welche in einer Merit Function (dt. Bewertungsfunktion) festgehalten werden, optimiert und für abbildende Systeme hinsichtlich der Anforderungen bewertet. Werden die Anforderungen erfüllt, erfolgt anschließend die Bewertung des Wirkungsgrades sowie die Identifikation von Streulicht im Rahmen der nicht-sequentiellen Strahlverfolgung. Die Anwendbarkeit der Methoden erfolgt am Beispiel eines hochauflösenden Scheinwerfers unter Verwendung eines DMDs zur Lichtmodulation und LEDs zur Lichterzeugung. Ausblickend wird unter anderem der Ansatz einer hybriden Strahlverfolgung zum Entwerfen diskutiert.

description: We aim to study the excitation conditions of the molecular gas in the rotating disk of the Red Rectangle, the only post-Asymptotic-Giant-Branch object in which the existence of an equatorial rotating disk has been demonstrated. For this purpose, we developed a complex numerical code that accurately treats radiative transfer in 2-D, adapted to the study of molecular lines from rotating disks. We present far-infrared Herschel/HIFI observations of the 12CO and 13CO J=6-5, J=10-9, and J=16-15 transitions in the Red Rectangle. We also present our code in detail and discuss the accuracy of its predictions, from comparison with well-tested codes. Theoretical line profiles are compared with the empirical data to deduce the physical conditions in the disk by means of model fitting. We conclude that our code is very efficient and produces reliable results. The comparison of the theoretical predictions with our observations reveals that the temperature of the Red Rectangle disk is typically ~ 100-150 K, about twice as high as previously deduced from mm-wave observations of lower-J lines. We discuss the relevance of these new temperature estimates for understanding the thermodynamics and dynamics of this prototype object, as well as for interpreting observations of other rarely studied post-AGB disks. Despite our sophisticated treatment of the line formation, our model cannot explain the relatively strong line-wing emission for intermediate-J transitions. We argue that a model including a rotating disk only cannot reproduce these data and suggest that there is an additional extended (probably bipolar) structure expanding at about 7--15 km/s.

description: Fluid flow and convective heat transfer in rotor-stator configurations, which are of great importance in different engineering applications, are treated in details in this review. The review focuses on convective heat transfer in predominantly outward air flow in the rotor-stator geometries with and without impinging jets and incorporates two main parts, namely, experimental/theoretical methodologies and geometries/results. Experimental methodologies include naphthalene sublimation techniques, steady state (thin layer) and transient (thermochromic liquid crystals) thermal measurements, thermocouples and infra-red cameras, hot-wire anemometry, laser Doppler and particle image velocimetry, laser plane and smoke generator. Theoretical approaches incorporate modern CFD computational tools (DNS, LES, RANS etc). Geometries and results part being mentioned starting from simple to complex elucidates cases of a free rotating disk, a single disk in the crossflow, single jets impinging onto stationary and rotating disk, rotor-stator systems without and with impinging single jets, as well as multiple jets. Conclusions to the review outline perspectives of the further extension of the investigations of different kinds of the rotor-stator systems and their applications in engineering practice.

description: The purpose of the study was to examine outsourcing effect on institutional performance in Ethiopian private commercial banks Dire Dawa District. Explanatory survey research design was employed and using quantitative methods. Stratified random sampling technique was used to select the respondents. The usable sample of 116 were used giving a response rate of 85%. The primary data gathered in the form of self-administer questionnaires with a Likert typed-scale. Ordered logistics regression were employed to satisfy specific objectives of this study. The analysis indicated that three outsourcing dimensions (Innovation Driven Outsourcing; Quality Driven Outsourcing and Cost Driven Outsourcing) have significant effects on the other hand, focus on core competencies driven outsourcing wasn’t significantly influence on institutional performance of private commercial banks. Thus, management team within private commercial banks strategic outsourcing is one way by which firms may build and sustain their core competencies, which is vital for survival. Therefore, a firm needs to create a focus around its core competencies, which entails handing over the activities of low strategic value to specialists who can do them better through strategic outsourcing.

Year: 2023

description: The study was concerned with assessing practices and challenges of tax audit in Oromia. To achieve this objective, a sample of 112 taxpayers and 42 tax officials with a questionnaire survey were conducted at Finfinne Branch Office of Oromia Revenue Authority, in Addis Ababa, for the year 2021/2022. Both descriptive and quantitative methods of analysis were used. In addition, interviews were conducted with Deputy Head, Branch Manager, Tax Audit Director and Tax Audit Team Leaders of ORA and the Branch office. The findings revealed that the practices to achieve ultimate goals of tax audit was found at moderate level; Tax Auditors of the Office do not make sufficient efforts to create Taxpayers’ awareness; they usually focus on increasing the collection of government tax revenue, including detecting tax evasion and avoidance, and not proportionally focus on all types of tax audit techniques. The finding further indicated that, majority of tax audit cases were usually selected using the criteria of the annual profit declared by taxpayers and there is no well-established strategy that makes tax audit case selection efficient and effective. Overall, the practices of tax audit at Branch Office were poorly practised. Regarding the challenges of tax audit, factors related with culture of corruption, estimation of tax amount; consideration of illegal ways of doing business; and absences of reliable and up-to-date record keeping practices among taxpayers were identified as the most severe challenges. Thus, managers in the tax administration should exert their strategic effort on the essential factors. Moreover, policymakers need to develop and apply improved schemes on key recommendations of the study include developing and utilising risk-based tax audit, coordinating sector offices’ efforts, and maintaining public trust in the tax administration. Future research should extend on the risk-based tax audit strategy and to catch up on the other unexplained factors by this study.

A Stochastic Grammar for Natural Shapes

Year: 2013
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: We consider object detection using a generic model for natural shapes. A common approach for object recognition involves matching object models directly to images. Another approach involves building intermediate representations via a generic grouping processes. We argue that these two processes (model-based recognition and grouping) may use similar computational mechanisms. By defining a generic model for shapes we can use model-based techniques to implement a mid-level vision grouping process.

description: Novice learners find motion as a continuous process of change challenging to understand. In this paper, we present a pedagogical approach based on agent-based, visual programming to address this issue. Integrating Logo programming with curricular science has been shown to be challenging in previous research on educational computing. We present a new Logo-based visual programming language - ViMAP - and, a sequence of learning activities involving programming and modeling, designed specifically to support seamless integration between programming and learning kinematics. We describe relevant affordances of the ViMAP environment that supports such seamless integration. We then present ViMAP-MoMo, a curricular unit designed in ViMAP for modeling kinematics, for a wide range of students (elementary - high school). The main contribution of this paper is that we describe in detail a sequence of learning activities in three phases, discuss the underlying rationale for each phase, and where relevant, report results in the form of observational data from two studies.
The interaction effects of financial development on slack and performance nexus of African firms
Creators: name: Hailu, Demis Hailegebreal
Publisher: name: Journal of Business and Administrative Studies
Year: 2023

description: While the resource-based theory argued that financial slack derives firm performance, agency theory asserted that it harms firm performance. Moreover, the pecking order and corporate finance theories argued that the well-functioning financial system eliminate the agency problems and asymmetric information; and could shape the corporate governance of firms, thereby facilitate the proper use of firms' internal finance. But existing literature completely overlooked this issue. This study thus investigated the interaction effects of the banking sector and the stock market development on slack performance nexus by using African sample firms. The result confirmed that financial development eliminates the adverse effects of high available slack on firm performance but create an undesirable impact of low available slack on firm performance. Conversely, financial development weakens the favorable effect of high potential slack on firm performance but aggravate the adverse effects of low potential slack on firm performance.

Year: 2023

description: The objective of the study is to examine the major causes of rework in Addis Ababa Building construction projects. To achieve the stated objective, a qualitative approach with descriptive research design is used. The building contractors’ one, two and three were selected as the target population. To elicit the required data, a simple random sampling with proportional method is used. Among the distributed 118 questionnaires for the construction companies, 89 were collected. Based on the collected data, the result of the study revealed that human resource capability, project communication, project constructability, site management; and materials equipment are the major causes of rework in the Ethiopian building construction companies. Finally, the study mainly recommended for the three major participants (contractors, clients, and consultants) to develop a continuous means of communication and specifically for the contractors and consultants to have a rework event, cause and impact recording system which is going to be helpful towards reducing its occurrence. Finally, managerial implications and concluding remarks are forwarded.

description: TThe study investigated the use and design of management accounting in a conglomerate business that produces both military and civilian products. Data were collected from interviews, video and document archives, and analyzed using a critical realist thematic approach with the assistance of MAXQDA software. The findings revealed that the organizational structure was largely symbolic, and budgeting and costing were not effectively utilized, with limited expression of plans in financial terms. Performance measurement was a combination of military, ideological, and business logic, with military discipline logic taking precedence over business efficiency and effectiveness in measuring performance. The focus was on output rather than process, with little considerations to financial performance measures. This suggests that management accounting is not a neutral tool for achieving organizational goals, but rather is used interchangeably with state ideology and military logic to balance ideological and political interests with business objective.

description: Pine cones show functionally highly resilient, hygroscopically actuated opening and closing movements, which are repeatable and function even in millions of years old, coalified cones. Although the functional morphology and biomechanics behind the individual seed scale motions are well understood, the initial opening of the cone, which is often accompanied by an audible cracking noise, is not. We therefore investigated the initial opening events of mature fresh cones of Scots pine (Pinus sylvestris) and their subsequent motion patterns. Using high-speed and time lapse videography, 3D digital image correlation techniques, force measurements, thermographic and chemical-rheological resin analyses, we are able to draw a holistic picture of the initial opening process involving the rupture of resin seals and very fast seed scale motion in the millisecond regime. The rapid cone opening was not accompanied by immediate seed release in our experiments and, therefore, cannot be assigned to ballistochory. As the involved passive hydraulic-elastic processes in cracking are very fine-tuned, we hypothesize that they are under tight mechanical-structural control to ensure an ecologically optimized seed release upon environmental conditions suitable for wind dispersal. In this context, we propose an interplay of humidity and temperature to be the external "drivers" for the initial cone opening, in which resin works as a crucial chemical-mechanical latch system.

description: The convolution approach, widely employed to describe final state interactions in the response of many-body systems, is derived from the expression of the nuclear response in the zeroth-order ladder approximation. Within this framework, the folding function, accounting for the effects of interactions between the struck particle and the spectator system, can be immediately related to the spectral function of particle states.The role of nucleon-nucleon correlations in determining the energy dependence is analyzed.

description: Aufgaben nehmen eine zentrale Rolle bei der Gestaltung von Lehr-Lern-Prozessen ein und ihre Passung für die Schüler*innen kann erhöht werden, indem sie an das Vorwissen und die Vorerfahrungen der Lernenden anknüpfen. Hierzu zählen der Kultusministerkonferenz (KMK 2013) zufolge mehrsprachige Kompetenzen (also die Fähigkeit eines Menschen, mehr als eine Einzelsprache zur Kommunikation zu nutzen), über die spätestens mit Einsetzen des Fremdsprachenunterrichts alle Schüler*innen verfügen. Die Einbindung von Mehrsprachigkeit in Schulbuchaufgaben bietet deshalb ein großes Potenzial, um über eine erhöhte Passung Lernprozesse verbessern zu können. Der vorliegende Beitrag stellt Ergebnisse einer empirischen Studie vor, die den Fragen nachgeht, a) inwiefern mehrsprachige Elemente in Schulbuchaufgaben aus Sachfächern der Sekundarstufe I aktuell eingebunden werden, b) wie diese Einbindungen mehrsprachigkeitsdidaktisch ausgestaltet sind und c) welches kognitive Aktivierungslevel sie aufweisen. Der Beitragstitel referiert mit der Nachfrage Einbindung oder Einbildung? auf das diesbezügliche Weiterentwicklungspotenzial von Schulbuchaufgaben, das bei der Untersuchung festgestellt wird. Der Beitrag schließt mit einer Diskussion, durch welche mehrsprachigkeitsdidaktischen Schärfungen die Nutzung der Lernangebote gestärkt und damit der individuelle Lernerfolg weiter erhöht werden könnte.
Robust synchronization of spin-torque oscillators with an LCR load

description: We study dynamics of a serial array of spin-torque-oscillators with a parallel inductor-capacitor-resistor (LCR) load. In a large range of parameters the fully synchronous regime, where all the oscillators have the same state and the output field is maximal, is shown to be stable. However, not always such a robust complete synchronization develops from the random initial state, in many cases nontrivial clustering is observed, with a partial synchronization resulting in a quasiperiodic or chaotic mean field dynamics.

description: We study the dynamics of ELKO in the context of accelerated phase of our universe. To avoid the fine tuning problem associated with the initial conditions, it is required that the dynamical equations lead to an early-time attractor. In the earlier works, it was shown that the dynamical equations containing ELKO fields do not lead to early-time stable fixed points. In this work, using redefinition of variables, we show that ELKO cosmology admits early-time stable fixed points. More interestingly, we show that ELKO cosmology admit two sets of attractor points corresponding to slow and fast-roll inflation. The fast-roll inflation attractor point is unqiue for ELKO as it is independent of the form of the potential. We also discuss the plausible choice of interaction terms in these two sets of attractor points and constraints on the coupling constant.

description: We study formation of solitons induced by counterflows of immiscible superfluids. Our setting is based on a quasi-one-dimensional binary Bose-Einstein condensate (BEC), composed of two immiscible components with large and small numbers of atoms in them. Assuming that the "small" component moves with constant velocity, either by itself, or being dragged by a moving trap, and intrudes into the "large" counterpart, the following results are obtained. Depending on the velocity, and on whether the small component moves in the absence or in the presence of the trap, two-component dark-bright solitons, scalar dark solitons, or multiple dark solitons may emerge, the latter outcome taking place due to breakdown of the superfluidity. We present two sets of analytical results to describe this phenomenology. In an intermediate velocity regime, where dark-bright solitons form, a reduction of the two-component Gross-Pitaevskii system to an integrable Mel'nikov system is developed, demonstrating that solitary waves of the former are very accurately described by analytically available solitons of the latter. In the high-velocity regime, where the breakdown of the superfluidity induces the formation of dark solitons and multi-soliton trains, an effective single-component description, in which a strongly localized wave packet of the "small" component acts as an effective potential for the "large" one, allows us to estimate the critical velocity beyond which the coherent structures emerge in good agreement with the numerical results.

Novel Functional Features of cGMP Substrate Proteins IRAG1 and IRAG2

subject: 540 Chemie

description: The inositol triphosphate-associated proteins IRAG1 and IRAG2 are cGMP kinase substrate proteins that regulate intracellular Ca2+. Previously, IRAG1 was discovered as a 125 kDa membrane protein at the endoplasmic reticulum, which is associated with the intracellular Ca2+ channel IP3R-I and the PKGIβ and inhibits IP3R-I upon PKGIβ-mediated phosphorylation. IRAG2 is a 75 kDa membrane protein homolog of IRAG1 and was recently also determined as a PKGI substrate. Several (patho-)physiological functions of IRAG1 and IRAG2 were meanwhile elucidated in a variety of human and murine tissues, e.g., of IRAG1 in various smooth muscles, heart, platelets, and other blood cells, of IRAG2 in the pancreas, heart, platelets, and taste cells. Hence, lack of IRAG1 or IRAG2 leads to diverse phenotypes in these organs, e.g., smooth muscle and platelet disorders or secretory deficiency, respectively. This review aims to highlight the recent research regarding these two regulatory proteins to envision their molecular and (patho-)physiological tasks and to unravel their functional interplay as possible (patho-)physiological counterparts.

The transition towards immortality: non-linear autocatalytic growth of citations to scientific papers

description: We discuss microscopic mechanisms of complex network growth, with the special emphasis of how these mechanisms can be evaluated from the measurements on real networks. As an example we consider the network of citations to scientific papers. Contrary to common belief that its growth is determined by the linear preferential attachment, our microscopic measurements show that it is driven by the nonlinear autocatalytic growth. This invalidates the scale-free hypothesis for the citation network. The nonlinearity is responsible for a dramatic dynamical phase transition: while the citation lifetime of majority of papers is 6-10 years, the highly-cited papers have practically infinite lifetime.
