Making High School Grades Meaningful, Thomas R. Guskey

Educational, School, and Counseling Psychology Faculty Publications

Most teachers base students' grades on more than one factor. The difficulty is figuring out how to weight and combine the different pieces that go into the final mark. Mr. Guskey suggests a system that not only avoids those problems but gives a better overall picture of a student's performance than the traditional single letter grade.

The Welding Fume Case And The Preemptive Effect Of Osha’S Hazcom Standard On Common Law Failure-To-Warn Claims, Richard C. Ausness

Law Faculty Scholarly Articles

The Occupational Health and Safety Act (the OSH Act) affects more than ninety million workers in the United States. The OSH Act is administered by the Occupational Health and Safety Administration (OSHA), which promulgates health and safety standards for the workplace. Although OSHA standards do not regulate product manufacturers directly, they may affect liability when manufacturers are sued by workers who are injured by allegedly defective products provided by their employers. With increasing frequency, manufacturers are contending that the OSH Act or OSHA standards preempt these claims. In particular, manufacturers argue that the Hazard Communication Standard (HazCom Standard) should preempt …

Privatizing Transportation Through Public-Private Partnerships: Definitions, Models, And Issues, Juita-Elena Wie Yusuf, Candice Y. Wallace, Merl Hackbart

Kentucky Transportation Center Research Report

There has been greater emphasis in recent times on using public-private partnerships (PPPs or P3s) to provide and deliver transportation infrastructure and services. These public-private partnerships differ from contracting out, being applicable to a broader range of projects and requiring different contract management and accountability. In the transportation arena the focus on public-private partnerships has resulted from both the need for greater reliance on private capital to fund critical infrastructure and services and the need to tap private sector expertise to ensure delivery of high quality infrastructure and services on time and on budget. This report serves as a primer …

Identification Of Pavement Distress In Kentucky, Tim C. Scully Jr., R. Clark Graves, David L. Allen

Kentucky Transportation Center Research Report

In Kentucky, the roads are comprised primarily of two types of pavement. The first being Portland Cement Concrete (PCC) a rigid pavement, and the other is Asphaltic Concrete (AC), a flexible pavement. There is a noticeable difference in their appearance, ride, cost and performance. Since Kentucky utilizes both pavements, as many states do, it is necessary to have a system in place to consistently identify pavement distress and categorize their overall performance.

Physical Conditions In The Interstellar Medium Toward Hd 185418, Gargi Shaw, Gary J. Ferland, R. Srianand, N. P. Abel

Physics and Astronomy Faculty Publications

We have developed a complete model of the hydrogen molecule as part of the spectral simulation code Cloudy. Our goal is to apply this to spectra of high-redshift star-forming regions where H₂ absorption is seen, but where few other details are known, to understand its implication for star formation. The microphysics of H₂ is intricate, and it is important to validate these numerical simulations in better understood environments. This paper studies a well-defined line of sight through the Galactic interstellar medium (ISM) as a test of the microphysics and methods we use. We present a self-consistent calculation of …

Evaluation Of Work Zone Safety Operations And Issues, Jerry G. Pigman, Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

Work zone activities are one of the areas with a high potential for compromised safety for workers and road users. Various measures have been taken to increase the level of safety in work zones; including the use of double fines for speeding and the application of speed displays based on radar detection. There has been an effort to improve the effectiveness and safety of flaggers by requiring the use of a stop/slow paddle for most work zone conditions, using lights on the paddle, and increasing visibility by using more reflective clothing. It has been suggested that safety in work zones …

Loss Of Sparc-Mediated Vegfr-1 Suppression After Injury Reveals A Novel Antiangiogenic Activity Of Vegf-A, Miho Nozaki, Eiji Sakurai, Brian J. Raisler, Judit Z. Baffi, Jassir Witta, Yuichiro Ogura, Rolf A. Brekken, E Helene Sage, Balamurali K. Ambati, Jayakrishna Ambati

Ophthalmology and Visual Science Faculty Publications

VEGF-A promotes angiogenesis in many tissues. Here we report that choroidal neovascularization (CNV) incited by injury was increased by excess VEGF-A before injury but was suppressed by VEGF-A after injury. This unorthodox antiangiogenic effect was mediated via VEGFR-1 activation and VEGFR-2 deactivation, the latter via Src homology domain 2-containing (SH2-containing) tyrosine phosphatase-1 (SHP-1). The VEGFR-1-specific ligand placental growth factor-1 (PlGF-1), but not VEGF-E, which selectively binds VEGFR-2, mimicked these responses. Excess VEGF-A increased CNV before injury because VEGFR-1 activation was silenced by secreted protein, acidic and rich in cysteine (SPARC). The transient decline of SPARC after injury revealed a temporal …
