Taft-Hartley Sections 301 and 303 Procedural Aspects

The motives and purposes behind the binate Sections 301 and 303, no less than other sections of the Taft-Hartley Act,\u27 are mixed and ambiguous. Foremost, however, seems the notion that Congress intended to create new federal rights, contract and tort, enforceable nationally in a federal forum. In broad terms, where the required relationship to interstate commerce exists, Section 301 permits suits by either employers or unions for violation of collective bargaining agreements; Section 303 permits those injured by certain boycotts and unlawful combinations to bring suit-- in both cases, the forum provided is the district court of the United States. It is not the purpose of this Note to discuss the elements or validity of a collective bargaining agreement or a breach thereof, nor of concern is the problem of the existence of the prohibited boycotts and combinations. The procedural provisions of Section 301 are incorporated by specific reference in Section 303. Subject to the always inherent difficulties of distinguishing substance from procedure, this Note will be concerned with procedural aspects of suits under the binate sections

Investigation of Flow Patterns in Various Wastewater Treatment Facilities

The theoretical hydraulic retention time of wastewater treatment plants is often used to predict the efficiency of treatment and to calculate operational parameters. However, these values are related to the actual hydraulic retention time. When there is a large discrepancy between the actual and predicted values, the actual hydraulic retention time can be determined by marking a parcel of wastewater and recording its passage through the system. This investigation utilized rhodamine WT, a fluorescent dye, to track the movement of wastewater through a stabilization lagoon and a rock-reed filter. The loss of rhodamine WT to sorption, biodegradation and photodegradation was determined as a means of predicting the need to increase dye dosage for future studies. The actual hydraulic retention time in the stabilization lagoon was found to be less than 5% of the theoretical. The history of blue-green algal blooms and accompanying odors in the lagoon were related to the extreme case of short circuiting and suspected stratification. The hydraulic retention time in the rock-reed filter was found to be approximately 136% of the theoretical. The extended retention time is possible explained by evapotranspiration and infiltration. The filter was not tested for its actual hydraulic retention time after its construction so no comparison was possible

Resolving the Gettier Problem in the Smith Case: The Donnellan Linguistic Approach

© 2018 Joseph Martin M. Jose and Napoleon M. Mabaquiao, Jr. In this paper, we contend that the Smith case in Gettier\u27s attempt to refute the justified true belief (JTB) account of knowledge does not work. This is because the said case fails to satisfy the truth condition, and thus is not a case of JTB at all. We demonstrate this claim using the framework of Donnellan\u27s distinction between the referential and attributive uses of definite descriptions. Accordingly, the truth value of Smith\u27s proposition The man who will get the job has ten coins in his pocket partly depends on how Smith uses the definite description the man who will get the job when he utters the proposition. Since, upon uttering the proposition, Smith has in mind a particular individual, namely Jones, and not just whoever will fit the attribute specified in the definite description, Smith uses the definite description referentially. And so when it turns out that it is Smith who eventually gets the job, the definite description fails to refer to Jones as intended by Smith, thereby making Smith\u27s proposition false. To think that Smith\u27s proposition is still true, in this regard, is to use the definite description attributively-that it is about whoever will fit the definite description. Apparently, when Gettier claims that Smith\u27s proposition is still true, to demonstrate that it is a case of JTB, he, in effect, imposes his attributive understanding of Smith\u27s usage of the definite description on Smith\u27s own epistemic situation

Antiparasitic and Antiproliferative Effects of Indoleamine 2,3-dioxygenase Enzyme Expression in Human Fibroblasts.

Studies were carried out to evaluate the proposed role of indoleamine 2,3-dioxygenase (INDO) induction in the antimicrobial and antiproliferative effects of gamma interferon (IFN-gamma) in human fibroblasts. The INDO cDNA coding region was cloned in the pMEP4 expression vector, containing the metallothionein (MTII) promoter in the sense (+ve) or the antisense (-ve) orientation. Human fibroblasts (GM637) stably transfected with the sense construct expressed INDO activity after treatment with CdCl2 or ZnSO4, but cells transfected with the antisense construct did not. The growth of Chlamydia psittaci was strongly inhibited in INDO +ve cells but not in INDO -ve cells after treatment with Cd2+ or Zn2+. The inhibition correlated with the level of INDO activity induced and could be reversed by the addition of excess tryptophan to the medium. The growth of Toxoplasma gondii was also strongly inhibited in INDO +ve cells but not in INDO -ve cells after treatment with Cd2+. Expression of Cd(2+)-induced INDO activity also inhibited thymidine incorporation and led to cytotoxicity in INDO +ve cells but not in INDO -ve cells. Thus, the induction of INDO activity by IFN-gamma may be an important factor in the antimicrobial and antiproliferative effects of IFN-gamma in human fibroblasts

Picture-Hanging Puzzles

We show how to hang a picture by wrapping rope around n nails, making a polynomial number of twists, such that the picture falls whenever any k out of the n nails get removed, and the picture remains hanging when fewer than k nails get removed. This construction makes for some fun mathematical magic performances. More generally, we characterize the possible Boolean functions characterizing when the picture falls in terms of which nails get removed as all monotone Boolean functions. This construction requires an exponential number of twists in the worst case, but exponential complexity is almost always necessary for general functions.Comment: 18 pages, 8 figures, 11 puzzles.
