Uses of management control and performance measurement systems by Deans and Heads in Australian universities: their effects on research, teaching and networking capabilities

Invoking a resource-based view (RBV), this study investigates relationships between management control systems (MCSs) use, including information use from performance measurement systems (PMSs), and organisational capabilities in the context of academic units of Australian universities. Increased competition and attention to distinctive capabilities amongst universities, particularly at their strategic operating unit level of a Faculty1 or School2, provides the setting for application of this theoretic perspective. Based on a questionnaire survey of all Faculty Deans and Heads of Schools in all 39 universities in Australia, evidence is provided on relationships between diagnostic and interactive use of MCSs, attention given to imposed and discretionary types of PMS information, the strength of capabilities of the academic unit and, in turn, overall performance of the academic unit. Highlights of findings are that Heads/Deans conceived capabilities of their unit in functional dimensions, not in generic dimensions as found in prior literature; interactive MCS use and imposed performance measures, respectively, direct relate to several types of capabilities and indirectly to performance of the academic unit, but diagnostic MCS use does not. The findings have practical implications for styles of control systems use and performance information use by management in universities.

Uses of the sampur in the halus (Refined) style of Yogyakarta court dance

In this essay I discuss how a familiar costume element in Javanese court dance, a long piece of patterned cloth known as the sampur, functions poetically through the ways it is used by the dancer. I elaborate on eight categories of use of the sampur, primarily from the point of view of a Western dancer first encountering the techniques of working with the scarf. I draw on scholars and other commentators to discuss the many dimensions of meaning embodied by these uses. The sampur emerges as a dance element rich in virtuosic potential and nuance, and resonant with numerous dimensions of cultural values.

Sturnus vulgaris, mitochondrial selection, MATLAB code and microsatellite data

Here we provide MATLAB code used to simulate drift and selection between and within individuals, which has been used to investigate mitochondrial haplotype frequency shifts in Sturnus vulgaris. Also provided is a microsatellite data set used to assess whether empirical allele frequency shifts were likely to be caused by admixture. These files support and upcoming publication, which concludes that within-individuals selection on mitochondrial DNA best explains empirical data.

CISR-ODE, A C plus plus framework with ODE solver for code based system dynamics simulation

Ordinary differential equations are used for modelling a wide range of dynamic systems. Even though there are many graphical software applications for this purpose, a fully customised solution for all problems is code-level programming of the model and solver. In this project, a free and open source C++ framework is designed to facilitate modelling in native code environment and fulfill the common simulation needs of control and many other engineering and science applications. The solvers of this project are obtained from ODEINT and specialised for Armadillo matrix library to provide an easy syntax and a fast execution. The solver code is minimised and its modification for users have become easier. There are several features added to the solvers such as controlling maximum step size, informing the solver about sudden input change and forcing custom times into the results and calling a custom method at these points. The comfort of the model designer, code readability, extendibility and model isolation have been considered in the structure of this framework. The application manages the output results, exporting and plotting them. Modifying the model has become more practical and a portion of corresponding codes are updated automatically. A set of libraries is provided for generation of output figures, matrix hashing, control system functions, profiling, etc. In this paper, an example of using this framework for a classical washout filter model is explained.

Defence against code injection attacks

Code injection attacks are considered serious threats to the Internet users. In this type of attack the attacker injects malicious codes in the user programs to change or divert the execution flows. In this paper we explore the contemporary defence strategies against code injection attacks (CIAs) and underline their limitations. To overcome these limitations, we suggest a number of countermeasure mechanisms for protecting from CIAs. Our key idea relies on the multiplexing technique to preserve the exact return code to ensure the integrity of program execution trace of shell code. This technique also maintains a FIFO (first in first out) queue to defeat the conflict state when multiple caller method makes a call simultaneously. Finally, our technique can provide better performance, in terms of protection and speed, in some point compared to the CFI (control flow integrity) as well as CPM (code pointer masking) techniques.

Análise não linear física e geométrica de pórticos espaciais

Apresenta-se uma formulação do tipo incrementaliterativa destinada a análise não linear de pórticos espaciais. Considera-se os efeitos não lineares introduzidos pelas mudanças de configuração geométrica da estrutura e também pela combinação destes efeitos com aqueles inerentes ao comportamento plástico exibido pelo material. As relações cinemáticas empregadas permitem a consideração de deslocamentos arbitrariamente grandes, acompanhadas de pequenas deformações . A modelagem do comportamento plástico do material é efetuada através do conceito de rótula plástica, estabelecido a partir de um critério de plastificação generalizado. Adota-se uma matriz de rigidez geométrica de barra baseada em momentos semitangenciais. Para elementos com extremos plastificados, é deduzida uma matriz de rigidez elasto-plástica. Emprega-se um método numérico do tipo incremental-iterativo, que utiliza como condição básica de controle da análise a constância do trabalho realizado pelos incrementos de cargas, em cada passo incremental (Método de Controle por Trabalho).A formulação permite uma descricão completa do desempenho mecânico da estrutura, inclusive em estágio de deformação pós-crítico em que ocorre regressão do carregamento com aumento de deslocamentos, ou vice-versa. A formulação foi implementada em um programa computacional elaborado em linguagem FORTRAN. Vários exemplos numéricos são apresentados para mostrar a eficiência das procedimentos propostos.

Empirical evidence of trade credit uses of brazilian publicly-listed companies

This research provides empirical evidence on the use of trade credit as either a substitution or a complement to bank debt for listed companies in Brazil, controlling for the firms reputation, as stated by Alphonse, Ducret and Séverin (2006). The sample consists of 263 publicly-listed companies for 2006. Our findings support all three hypotheses. We provide evidence that trade credit may be used as a signal for the firm’s quality.

Dip financing of financially distressed companies in Brazil – the conditions provided by the brazilian bankruptcy law act as real incentives for dip lenders as in chapter 11 of the American bankruptcy code?

O objeto deste trabalho é a compreensão do financiamento de empresas em crise, mais especificamente, o financiamento concedido após o pedido de recuperação judicial, como forma de permitir que a empresa saia da situação de crise e retorne à condição de normalidade. Para tanto, nos apropriando do termo cunhado pela doutrina norte-americana, para fazer referência ao aporte de recursos em empresas em dificuldade, utilizaremos o termo DIP financing ou financiamento DIP. Para uma compreensão adequada do objeto, é necessário que entendamos a origem do DIP financing nos Estados Unidos e como é a regulação norte-americana sobre a matéria atualmente. O segundo passo será avaliar a possibilidade de aplicação da mesma estrutura de aporte de recursos no Brasil. Ao estudarmos a origem desse mecanismo nos Estados Unidos, veremos os problemas que surgiram ao longo dos anos e como foram superados jurisprudencialmente e doutrinariamente para que o financiamento DIP se consolidasse como uma das formas de aporte de capital em empresas em crise, culminando no desenvolvimento de uma verdadeira indústria de crédito às empresas em dificuldade. Uma análise dos problemas enfrentados pelo sistema falimentar americano nos levará a hipótese de que, a menos que sejam afirmados mecanismos que assegurem a quem concede o financiamento após o pedido de recuperação judicial, uma super prioridade no recebimento após a recuperação judicial, será possível o desenvolvimento de um mercado de DIP financing no Brasil.

Sociedade em conta de participação : riscos de descaracterização do tipo societário e suas consequências

Este trabalho se dispõe a analisar as características das sociedades em conta de participação ou SCP’s, seus principais usos, os riscos de sua descaracterização e suas respectivas consequências. As SCP’s experimentaram crescimento de sua importância e uso nos últimos anos, sendo constatadas na estruturação de diversos tipos de negócios, com destaque na área imobiliária e na realização de investimentos. Como um dos tipos societários admitidos pela legislação, as SCP’s possuem grande plasticidade em sua utilização, adaptando-se às diversas necessidades de seus usuários. Algumas características específicas, no entanto, devem ser observadas pelas partes, sob risco de sua descaracterização. É o caso do papel dos sócios participantes, que não poderão se envolver na execução do objeto da SCP, nem contribuir para a formação do seu patrimônio especial com serviços que tenham relação direta com o seu objeto. E os riscos vão além daqueles previstos no Código Civil, que aponta a solidariedade, com o sócio ostensivo, do sócio participante perante terceiros afetados. Do ponto de vista fiscal, poderá haver a descaracterização da SCP para se considerar a prestação de serviços, quando ocorrerá a incidência de tributos sobre os pagamentos feitos ao sócio participante a título de dividendos. Outros riscos e consequências em modelos de negócio adotados foram explorados e apontados ao longo do trabalho, em que as SCP’s são utilizadas para dissimular uma situação jurídica, de modo a gozar de alguma vantagem. É o caso da previsão de distribuição de resultado em SCP com bens ou coisa certa e não com capital, poderia dissimular um contrato de compra e venda, e quando tal SCP for formada por um grupo de pessoas, poderia dissimular um consórcio para entrega de bens, regido pela Lei 11.795/2008. A divulgação pública de SCP, para captação de investidores, poderia caracterizar a operação como um contrato de investimento coletivo, regulado pela Lei 6.385/1976. Ao final foram listados, como sugestão, alguns cuidados a serem observados para se evitar os riscos apontados ao longo deste trabalho.

Local Field Potentials in the Gustatory Cortex Carry Taste Information

It has been recently shownthat localfield potentials (LFPs)fromthe auditory and visual cortices carry information about sensory stimuli, but whether this is a universal property of sensory cortices remains to be determined. Moreover, little is known about the temporal dynamics of sensory information contained in LFPs following stimulus onset. Here we investigated the time course of the amount of stimulus information in LFPs and spikes from the gustatory cortex of awake rats subjected to tastants and water delivery on the tongue. We found that the phase and amplitude of multiple LFP frequencies carry information about stimuli, which have specific time courses after stimulus delivery. The information carried by LFP phase and amplitude was independent within frequency bands, since the joint information exhibited neither synergy nor redundancy. Tastant information in LFPs was also independent and had a different time course from the information carried by spikes. These findings support the hypothesis that the brain uses different frequency channels to dynamically code for multiple features of a stimulus.

Compressão de Imagens Usando a Função de Peano e a Transformada Wavelet 1D

In this work, spoke about the importance of image compression for the industry, it is known that processing and image storage is always a challenge in petrobrás to optimize the storage time and store a maximum number of images and data. We present an interactive system for processing and storing images in the wavelet domain and an interface for digital image processing. The proposal is based on the Peano function and wavelet transform in 1D. The storage system aims to optimize the computational space, both for storage and for transmission of images. Being necessary to the application of the Peano function to linearize the images and the 1D wavelet transform to decompose it. These applications allow you to extract relevant information for the storage of an image with a lower computational cost and with a very small margin of error when comparing the images, original and processed, ie, there is little loss of quality when applying the processing system presented . The results obtained from the information extracted from the images are displayed in a graphical interface. It is through the graphical user interface that the user uses the files to view and analyze the results of the programs directly on the computer screen without the worry of dealing with the source code. The graphical user interface, programs for image processing via Peano Function and Wavelet Transform 1D, were developed in Java language, allowing a direct exchange of information between them and the user
