Eating Heavily: Men Eat More in the Company of Women

Kevin M. Kniffin, & Brian Wansink
Sexual selection has been commonly considered by evolutionary psychologists interested in eating disorders among women; however, comparable attention has not been paid to problematic eating by men. We present the results of a field study through which we find that men eat more food when sharing a meal with women than with men. Notably, men appear to eat larger quantities of both unhealthy (pizza) and healthy (salad) food when in the company of women. More...

A Metametadata Architecture Forpedagogic Data Description

, , &
This paper focuses on a novel method for semantic searching and retrieval of information about learning materials. Metametadata encapsulate metadata instances by using the properties and attributes provided by ontologies rather than describing learning objects. A novel metametadata taxonomy has been developed which provides the basis for a semantic search engine to extract, match and map queries to retrieve relevant results. The use of ontological views is a foundation for viewing the pedagogical content of...

Enhanced Performance Of Fading Dispersive Channel Using Dynamic Frequency Hopping(Dfh)

Walid M. Saad
techniques are examined to overcome the performance degradation caused by the channel dispersion using slow frequency hopping (SFH) with dynamic frequency hopping (DFH) pattern adaptation. In DFH systems, the frequency slots are selected by continuous quality monitoring of all frequencies available in a system and modification of hopping patterns for each individual link based on replacing slots which its signal to interference ratio (SIR) measurement is below a required threshold. Simulation results will show the...

Approximation Incremental Training Algorithm Based On A Changeable Training Set

Yi-Fan Zhu, Wei Zhang, Xuan Zhou, Qun Li & Yong-Lin Lei
The quick training algorithms and accurate solution procedure for incremental learning aim at improving the efficiency of training of SVR, whereas there are some disadvantages for them, i.e. the nonconvergence of the formers for changeable training set and the inefficiency of the latter for a massive dataset. In order to handle the problems, a new training algorithm for a changeable training set, named Approximation Incremental Training Algorithm (AITA), was proposed. This paper explored the reason...

Why Do Clawback Provisions Affect Financial Reporting Quality? - An Analysis Of Trigger Effects

Yu-Chun Lin
We identify clawback triggers from firms- proxy statements (Form DEF 14A) and use the likelihood of restatements to proxy for financial reporting quality. Based on a sample of 578 U.S. firms that voluntarily adopt clawback provisions during 2003-2009, when restatement-based triggers could be decomposed into two types: fraud and unintentional error, and we do observe the evidence that using fraud triggers is associated with high financial reporting quality. The findings support that fraud triggers can...

The Anti-Noise System For Rail Brakes On Hump Yards

Brigita Altenbaher
The friction between two metal surfaces results in a high frequency noise (squealing) which also occurs during the braking of wagons with rail brakes in the process of shunting at a marshalling yard with a hump. At that point the noise level may exceed 130dB, which is extremely unpleasant for workers and inhabitants. In our research we developed a new composite material which does not change braking properties, is capable of taking extremely high pressure...

Natural Flickering Of Methane Diffusion Flames

, &
Present study focuses on studying the oscillatory behavior of jet diffusion flames. At a particular jet exit velocity, the flames are seen to exhibit natural flickering. Initially the flickering process is not continuous. In this transition region as well as in the continuous flickering regime, the flickering displays multiple frequency oscillations. The response of the flame to the exit velocity profile of the burner is also studied using three types of burners. The entire range...

Conflict, Confusion, Choice: A Phenomenological Approach To Acts Of Corruption

Yvonne T. Haigh
Public sector corruption has long-term and damaging effects that are deep and broad. Addressing corruption relies on understanding the drivers that precipitate acts of corruption and developing educational programs that target areas of vulnerability. This paper provides an innovative approach to explore the nature of corruption by drawing on the perceptions and ideas of a group of public servants who have been part of a corruption investigation. The paper examines these reflections through the ideas...

Main Elements Of Soft Cost In Green Buildings

M.A. Nurul Zahirah &
Green buildings have been commonly cited to be more expensive than conventional buildings. However, limited research has been conducted to clearly identify elements that contribute to this cost differential. The construction cost of buildings can be typically divided into "hard" costs and "soft" cost elements. Using a review analysis of existing literature, the study identified six main elements in green buildings that contribute to the general cost elements that are "soft" in nature. The six...

Synthesis And Characterization Of Zno And Fe3O4 Nanocrystals From Oleat-Based Organometallic Compounds

, , , , , Muhammad Azmi Abd-Hamid & ChinHua Chia
Magnetic and semiconductor nanomaterials exhibit novel magnetic and optical properties owing to their unique size and shape-dependent effects. With shrinking the size down to nanoscale region, various anomalous properties that normally not present in bulk start to dominate. Ability in harnessing of these anomalous properties for the design of various advance electronic devices is strictly dependent on synthetic strategies. Hence, current research has focused on developing a rational synthetic control to produce high quality nanocrystals...
