These determinants concern the legal system of country, investment opportunity set and ownership structure which have influence of audit quality.Empirical results show, initially, that specificities of legal system are positively associated with audit quality appreciated by size of audit firm. Then, the results reveal that investment opportunity set influences partially size of audit firm. Finally, ownership structure influences negatively the search for a high audit quality展开更多

The management of the Malaysian public sector is continuously maturing in facilitating foreign input in national development, echoing similar advances expounded by the internal audit units of private sector organizations. The main difference being the public sector addresses the interest of a much wider group of stakeholders. Rapid development in infrastructures and industries positioned Malaysia on the fringes of globalization and the world market. This enlarges the crucial role of internal auditing to ensure transparency, integrity, quality and improved service delivery; among myriad positive aims, remain the end point of any process area. This study explored the significance of internal auditing in the Malaysian public sector, and its subsequent extent and influence in public sector hierarchy and decision making. Data was collected from responses to a questionnaire distributed to head of internal auditors, internal auditors and other staff of internal audit departments from various categories of public sector departments and agencies in Malaysia. The study concluded that the internal audit function in the public sector in Malaysia is curtailed by understaffing and hampered by inadequate support from top management while, the auditors seldom extend their full cooperation. The auditors themselves lack appropriate knowledge and training on effective auditing approaches. The negative perception accorded to internal audit led to inaction by management on recommended remedies which only serve to nullify the positive contribution internal audit potentially holds to elevate the service delivery quality of the public sector.展开更多

In such a scheme, one Private Key Generator(PKG) is employed to authenticate the identity and generate private keys for all users, and one Third Party Auditor(TPA) is employed to by users to check the integrity of cloud data. This approach is undesirable for large-scale users since the PKG and the TPA might not be able to afford the heavy workload. To solve the problem, we give a hierarchical Private Key Generator structure for large-scale user groups, in which a root PKG delegates lower-level PKGs to generate private keys and authenticate identities. Based on the proposed structure, we propose an authorized identity-based public cloud storage auditing scheme, in which the lowest-level PKGs play the role of TPA, and only the authorized lowest-level PKGs can represent users in their domains to check cloud data's integrity. Furthermore, we give the formal security analysis and experimental results, which show that our proposed scheme is secure and efficient.展开更多

The theory of action that is appealed to is one that emphasizes the calculative "means-ends" structure of rational deliberation--a structuring that appears to place practical reasoning at odds with other forms of causal explanation. The epiphenomenalist view presented is one that attempts to preserve certain foundational tenets of physicalism in the face of worries generated by the existence of qualia. In the latter part of the paper, the author makes use of a novel thought experiment involving phenomenal qualia in order to undermine the epiphenomenalist position and to vindicate the view that properties of consciousness matter to human agency.展开更多

At this time, there is a predominant emphasis on culture-related differences of processes and workflows in companies in the main body of articles on cross-cultural management research. This paper proposes an extension of these research efforts in that case that the different efficiencies of these processes, resulting from cultural influences, should be examined in more detail. Based on the beginnings of organizational theory and with practical examples, it has been already verified that cultural influences shape organizational structures as well as organizational processes. This kind of fact should lead to the assumption that these cultural influences should also create differences in their efficiency, depending on what kind of culture the companies are. These differences in efficiency can be regarded as opportunities for success from which further competitive advantages can be derived. As that the examination of differences in efficiency of processes is still a rarity in the field of cross-cultural management research this should be developed further.展开更多

These benefits are expressed in monetary units by using the CVM (Contingent Valuation Method). The maintenance of the urban environment often entails excessive costs paid by the people through taxation. A city free of aesthetic pollution results in an increase in tourism. A portion of taxation paid by the citizens is allocated to cleaning the city. An increase in tourism provides the government with additional revenue through VAT (Value Added Taxes). The main findings show that in a large proportion, 28% of the interviewees are willing to pay, but those that are willing to pay significant amounts tend to prefer mild interventions to the buildings, while those (42%) that agree with minimal to null amount demand radical intervention. The latter group, also, considers any contribution of theirs to restoration as unfair, judging that this expenditure should be covered exclusively by the State. Last but not least, from a sociopsychological point of view, this attitude could be attributed to extreme personalities which tend to prefer more holistic and direct solutions (i.e., no mixed strategy involving people and the State is acceptable by interviewees who considered themselves as having no further obligations after regular tax-paying); as a result, they think that the State is exclusively responsible to resolve the situation.展开更多

Their primary goal has functionality and efficiency rather than aesthetic considerations and, yet from a time perspective, they still impress with their beauty and perfection. Gradually, architects began to take care of the form of bridges, as in the case of the Rialto Bridge in Venice. Nowadays, the most renowned architects, with Norman Foster in the lead, take up the design of bridge "architecture". Although technical solutions remain top priority, aesthetic qualities are widely recognized and appreciated.展开更多

An entirely new approach in formation of the facade and roof planes as well as of the forms of structures whose appearance resemble sculptural creations has been analyzed. The buildings from all over the world, with different functions contents, indicate a tendency of a different understanding of interpretation of physical structures and correlation with natural and artifact environment. Water surfaces and vegetative material contribute to an effective, cultural, majestic impression of engineering-technological philosophy of city building. The examples in the paper suggest the obvious need of radical changing of the way of thinking in the application of the design strategy in conceptualization of urban agglomerations, and essentially important, conceptually inspired metabolic of relationships among the spatial structures. The world entered new non-globalization trends of creation of the city memory, of the new iconically, symbolically strong, non-cliché, non-standard forms which define the contemporary cultural-artistic and historical identity of macro-ambient entities. This is a good and encouraging sign.展开更多

This study uses the joint tenure between audit partners and management to explain audit quality, because corporate directors would consider an appropriate adjustment in the management to deal with a dramatic change in the external environment. First, we examined whether there is a significant association between audit partner tenure and audit quality after the implementation of mandatory audit partner rotation by using the auditor tenure only. We addressed this issue by using a sample of Taiwan Residents companies and found no significant association between audit partner tenure and the magnitude of discretionary accruals (DA), a common proxy for audit quality. Second, we tested the relationship between audit partner tenure and audit quality under the consideration of industry structure stability. The result exhibits a negative relation between audit partner tenure and audit quality under the control of industry structural stability which is measured by a proxy variable, the joint tenure between audit partner and management. Third, we investigated whether the association does exist between joint tenure of auditors and management and audit quality. We also addressed this issue by using Taiwan Residents data and found a significant association between the joint tenure of auditor and management and the magnitude of DA. Our findings provide evidence that the use of a mandatory rotation rule is an ineffective way to improve audit quality.展开更多

The aim of this paper is to develop the guidelines that could be applied in the design of a space structure in order to achieve the optimal overall lifetime performance of the space structure. Space structures are more than inanimate hunks of metal, glass and fabric. Every space structure that we design as structural engineers is like a child - a child that is conceived with a passionate vision of its form, structure and purpose; nurtured through the schematic design phase and the development of construction documents; and cared for during the labor pains of plan check corrections, requests for information, shop drawing review, and construction observation. Like children, our space structures mature, perform necessary functions during their lives, and eventually, grow old and die. The design of a sustainable space structure is a much more challenging and cross-disciplinary process than in the past and therefore it is necessary that the space structure is viewed as an integrated system and that all members of the design team work in a fully integrated fashion.展开更多

Because of the enormous influence of media supervision and the uncertainty of its outcomes, the relationship between the media and the court has always been tense. Currently, the main model of media trial supervision centers on trial results; that is, media questions and criticisms tend to revolve around the substantive outcome of the trial in the hope that the courts will change the verdict. This supervisory model potentially risks encroaching on judicial independence. In the context of China's transitional society, such risks will be hard to control and will often develop into immediate social conflicts, jeopardizing the impartiality of the trial. To avoid this, the model of media supervision centered on trial results should shift to one centered on the conduct of the trial.展开更多

However, if distress vocalizations produced by different species and in different contexts share a common motivational state and associated neurochemical pathways, we can expect them to share a common acoustic structure and adaptive function, showing only limited variation that corresponds to the infant's level of arousal. Based on this premise, we review the acoustic structure and adaptive function of two types of distress calls, those given when infants were isolated from their mothers (isolation caUs) or captured by humans (capture calls). We conducted a within-context comparison examining the two call types across a diverse se- lection of mammalian species and other vertebrate groups, followed by a comparison of how acoustic structure and function dif- fers between these contexts. In addition, we assessed acoustic traits that are critical to the response of caregivers. Across verte- brate species, distress vocalizations produced in these two behavioral contexts tend to be tonal with a simple chevron, flat or de- scending pattern of frequency modulation. Reports that both isolation and capture calls of vertebrate infants serve to attract care- givers are universal, and the fundamental frequency of infant vocalizations is often critical to this response. The results of our re- view are consistent with the hypothesis that differences in the acoustic structure of isolation and capture distress vocalizations re- flect differences in arousal, and not discrete functions. The similarity in acoustic structure and caregiver response observed across vertebrates adds support to the hypothesis that the production and processing of distress vocalizations are part of a highly-conserved system of social vocal behaviour in vertebrates. Bioacoustic research may move forward by recognizing the commonality among different forms of infant solicitations that attract caregivers, and the commonality of these solicitations with vocalizations that attract conspecifics in still other behavioral contexts [Current Zoology 58 (5): 698-726, 2012].展开更多

The material configuration and fabrication of the nanopore has become one important consideration in the nanopore based DNA sequencing research. Among various materials, the newly emerged graphene has brought more opportunities to the development of sequencing technology because of its unique structures and properties. This review mainly focuses on the experimental aspects of graphene nanopore research including the nanopore fabrication methods and processes. Meanwhile, the challenges in the present graphene nanopore research including hydrophobicity, translocation velocity and noise are also addressed and discussed.展开更多
