Group Work: Effects of Previous Peer Interactions
The research conducted through a student survey will provide insight as to whether or not past peer interactions through group work have tainted or influenced students\u27 feelings towards group work today. A survey will be administered to seventh grade middle school students from two local schools in Northwest Indiana. The purpose of this research study is to help shape the way educators understand student feelings toward group work before assigning peers together and expecting results or products
Combining Static and Dynamic Analysis for Vulnerability Detection
In this paper, we present a hybrid approach for buffer overflow detection in
C code. The approach makes use of static and dynamic analysis of the
application under investigation. The static part consists in calculating taint
dependency sequences (TDS) between user controlled inputs and vulnerable
statements. This process is akin to program slice of interest to calculate
tainted data- and control-flow path which exhibits the dependence between
tainted program inputs and vulnerable statements in the code. The dynamic part
consists of executing the program along TDSs to trigger the vulnerability by
generating suitable inputs. We use genetic algorithm to generate inputs. We
propose a fitness function that approximates the program behavior (control
flow) based on the frequencies of the statements along TDSs. This runtime
aspect makes the approach faster and accurate. We provide experimental results
on the Verisec benchmark to validate our approach.Comment: There are 15 pages with 1 figur
Hester Prynne, Lydia Bennet, and Section 306 Stock: The Concept of Tainting in the American Novel, the British Novel, and the Internal Revenue Code
Did Nathaniel Hawthorne\u27s novel, The Scarlet Letter, inspire Section 306 of the Internal Revenue Code? This code provision adopts a peculiarly Hawthorne-like solution to a tax avoidance scheme known as the preferred stock bailout. Section 306 taints the stock used in the scheme as Section 306 stock. Special rules then govern all subsequent dispositions of the tainted stock. With its concept of a taint that can dog a stock from acquisition to disposition, Section 306 might have been designed by a novelist rather than a tax technician
Legislative Alert: The Regulations from the Executive in Need of Scrutiny (the REINS Act), the Regulatory Accountability Act and the Regulatory Flexibility Improvements Act (H.R.10) (H.R.3010) (H.R. 527)
[Excerpt] When the Congress returns from the Thanksgiving break the House is expected to vote on three regulatory reform\u27* bills - H.R. 10, the Regulations from the Executive in Need of Scrutiny (the REINS Act). H.R. 3010, the Regulatory Accountability Act and H.R. 527, the Regulatory Flexibility Improvements Act. Each of these bills would up-end the entire regulatory system making it impossible for the government to protect workers and the public from workplace hazards, dirty air and water, unsafe drugs, tainted food and Wall Street abuses. The AFL-CIO strongly urges you to oppose each of these bills
Class, race, gender and the production of knowledge: considerations on the decolonisation of knowledge
How do class, race and gender impact on the production of knowledge? Is it enough to include those who have been excluded from advanced knowledge? Or has knowledge itself been tainted by the exclusions of class, race, gender and colonial conquest? How to proceed with such realisations? How do we decolonise our minds and our universities? Should we repudiate existing knowledge and start again at zero? Or should we return to the indigenous knowledge of our ancestors? Or should we engage in a radical and critical transformation? How has Rhodes Must Fall dramatised these dilemmas? What does Marxism have to offer in working through these issues
The Pentatomoidea (Hemiptera) of Northeastern North America with Emphasis on the Fauna of Illinois. J. E. McPherson. 240 pages. Southern Illinois University Press, Carbondale, 1982. $30.00.
(excerpt)
Among the most conspicuous of the true bugs are the pentatomoid Hemiptera, stink bugs and their relatives, many of which are large, or moderately so, and brightly colored. Unwary berry pickers probably can recount an unpleasant experience with fruit tainted by the noisome odor of a stink bug, and the characteristic, barrel-shaped eggs of most Pentatomidae, often ornate and arranged in neat rows, have evoked the wonderment of naturalists and prompted numerous technical descriptions from entomologists. Contributing to the importance of this group are the crop losses inflicted by certain plant-feeding species and the destruction of insect pests by predatory stink bugs (Asopinae)
Investigation of taste tainting in salmon flesh in the Ribble catchment
This report presents the findings of the first phase of an investigation into the cause(s) of taints in salmonid fish in the River Ribble, commissioned by the North West Region of the Environment Agency. There have been reports of tainting in fish taken from both the estuary and the freshwater river for many years, but the contaminants involved and their source and transport pathway are unknown. Tainting by phenols has been of specific concern in the past.
The work programme comprised: examination of tainting reports; collection of salmonids; their submission for taste testing; literature review; analysis of fish flesh using gas chromatography-mass spectrometry (GCMS) and analysis of river bed sediments. From enquiries, three common descriptors of the 'taint' were identified: disinfectanty; diesely; and muddy. The incidence of taints appears transient/irregular and may therefore relate to
the incidence of discharges and specific threshold concentrations of pollutants. The literature review showed that a wide range of organic compounds including many industrial chemicals, and others which are naturally occurring, can taint fish flesh. Taste testing confirmed the presence of tainted salmon and trout in the Ribbie Catchment. It identified a low incidence of 'untainted' fish but demonstrated the 'taint' to be not specific to
one tainting substance. Differences were found both between the species and fish from different parts of the catchment. Overall, most fish exhibited an unpleasant flavour, though
this may have been influenced to some extent by the fact that most were sexually mature.
The worst tainting was found in trout from the river Calder: a soapy/chemical aftertaste. An unpleasant earthy/musty flavour distinguished the salmon from the trout. Phenol was shown to have been a minor issue during the present study, whilst no hydrocarbon taints were
identified.
Examination of tissue from the eight salmon exhibiting the worst taints revealed the presence of aromatic hydrocarbons, but no phenolic compounds. Other notable substances present in the fish were siioxanes and benzophenone. Data from sediment analysis is presented which shows the main compounds present to be aromatic and polyaromatic hydrocarbons, that concentrations at two locations R. Darwen and R. Calder were significantly higher than at other sites, and that some phenolic compounds were detected at low levels.
A paucity of fish flesh taste descriptors linked to specific compounds prevented an obvious correlation to be made between the tastes observed and the organic compounds detected.
Descriptors frequently used by the taste testing panel (e.g. earthy, musty, astringency, chemical) cannot be linked to any of the compounds identified in the tissue analyses. No taste information was available from the literature on siioxanes. Aromatic hydrocarbons though present in tissue and sediments were not identified as tainting
