Agency Theory And Audit Quality, Burim Isa Berisha Bb

International Journal of Business and Technology

Auditing plays a vital role in reducing both: information asymmetry by empirically confi rming the validity of fi nancial statements and agency problems. The principal- agent confl ict illustrated in agency theory, where principal (owner) lack reasons to believe their agents (managers) because of information asymmetries and contradictory motives. Information asymmetry deals with the study of decisions in transactions where one party has more or superior information than other. Agents (either directors or auditors) may be trustworthy without further incentives to align interest or monitoring strategies such as audit or increased regulation. However, the simple agency model would recommend that …

Background To Auditing And Role Of Auditor, Burim I. Berisha B.B

International Journal of Business and Technology

Financial markets crisis since 2007 has unfolded many issues regarding the supervision of financial institutions, financial reporting and auditing as of core importance to many regulatory bodies in order to ensure proper-functioning framework in the internal market. An audit, along with both adequate supervision and corporate governance, can contribute towards the financial health of the companies by providing assurance in terms of bringing financial stability into their reports (European Commission [EC], 2010, p. 3).

Strategic Nuclear Weapons For Planetary Defense, James Howe

Space and Defense

The planet Earth is continually under bombardment. Each day, roughly 100 tons of small meteoroids and space debris – some as large as a meter in diameter, but most smaller than a grain of sand – strike the atmosphere. Moving at speeds in excess of 40,000 kilometers per hour, these meteoroids are often seen as bright streaks in the sky as they burn up from atmospheric friction. Fortunately, because they are consumed high in the atmosphere, meteoroids and space dust pose no threat to humans or other life on Earth.

Transport Barriers Influence The Activation Of Anti-Tumor Immunity: A Systems Biology Analysis, Mohammad R. Nikmaneshi, James W. Baish, Hengbo Zhou, Lance L. Munn

Faculty Journal Articles

Effective anti-cancer immune responses require activation of one or more naïve T cells. If the correct naïve T cell encounters its cognate antigen presented by an antigen presenting cell, then the T cell can activate and proliferate. Here, mathematical modeling is used to explore the possibility that immune activation in lymph nodes is a rate-limiting step in anti-cancer immunity and can affect response rates to immune checkpoint therapy. The model provides a mechanistic framework for optimizing cancer immunotherapy and developing testable solutions to unleash anti-tumor immune responses for more patients with cancer. The results show that antigen production rate and …

Materials Science and Engineering Faculty Publications and Presentations

A bacteriochlorophyll a (Bchla) dimer is a basic functional unit in the LH1 and LH2 photosynthetic pigment–protein antenna complexes of purple bacteria, where an ordered, close arrangement of Bchla pigments—secured by noncovalent bonding to a protein template—enables exciton delocalization at room temperature. Stable and tunable synthetic analogs of this key photosynthetic subunit could lead to facile engineering of exciton-based systems such as in artificial photosynthesis, organic optoelectronics, and molecular quantum computing.
