A Century of Case Method: An Apologia

This article will review the case method and the alternatives from the viewpoint of a seasoned-practitioner-turned-law-teacher. I will examine some of the criticisms of the method and offer some observations not heretofore made in the debate. It is hoped that this may help law students better understand the wisdom behind the use of the much maligned case method, which is still used in one form or another by the vast majority of American law professors

Need for More Professors Who Have Practiced Law

I was delighted to receive recently a copy of a letter from the distinguished faculty advisor of the Cleveland-Marshall Law Review, inviting law faculty members, whenever they are seeking a vehicle for expression, to send short un-annotated articles about a pet idea or gripe in legal education. After having practiced law for fourteen years and (after having been turned down by some of the best law schools in the country) having taught law for the past year, I now feel eminently qualified to write just that type of unscholarly article

Tailoring optical fields emitted by nanometric sources

Here we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is the careful tuning of NP's damping factors, which changes the eigenmode's decay rates of the whole array. This, at long time, leads to a locking of relative phases and frequencies of individual localized-surfaces-plasmons (LSPs) and, thus, controlls the emitted field. The amplitude of the LSP's oscillations can be kept constant by embedding the system in optical active media. In the case of full loss compensation, this implies that, not only the relative phases, but also the amplitudes of the LSPs remain fixed, leading us, additionally, to interpret the process as a new example of synchronization. The proposed approach can be used as a general way of controlling and designing the electromagnetic fields emitted by nanometric sources, which can find applications in optoelectronic, nanoscale lithography and probing microscopy

Modeling and simulation of an emulsion copolymerization process

Radical emulsion copolymerization is one of the most widely diffused processes aimed to produce paints easy to use because of their low viscosity. At industrial scale, such processes require a high control level of all the operating variables. Particularly, the repeatability of an emulsion polymerization process within narrow limits is one of the most desirable features because it allows for controlling also other important product qualities as final solids content, average particle size, latex viscosity and polymer average molecular weight. Other important full plant requirements are the minimization of reactants dosing times and the preparation of a latex at the highest possible concentration. In this work, the first step of a complex industrial copolymerization process has been considered. Since different monomer types (butyl acrylate, styrene, acrylic acid and acrylamide) are involved, it has been necessary to propose a complete set of rate constants for all the traditional steps of the radical emulsion reactions chain (i.e. initiation, propagation, radicals termination, backbiting and long-chain branching, micelles seeding, etc..). These parameters have then been inserted into a system of ordinary differential equations expressing all balances and control actions aimed to simulate the full plant synthesis. Finally, the proposed model has been experimentally validated through the comparison with a reaction calorimetry test carried out in an indirectly cooled semibatch reactor (RC1, 1L, Mettler Toledo). Obtained results have confirmed the reliability of the theoretical model

Cybersecurity program for Philippine higher education institutions: A multiple-case study

Digital technology has become an integral aspect of an educational system. Every state university funded the creation of Information Technology Offices to secure its Management Information System. The challenge on cybersecurity threatens the intellectual capital of students especially in a research university, theft of crucial information, and financial loss. The current study is a multiple case study of cybersecurity threats and challenges of Selected Philippine State Universities and Colleges in the National Capital Region. Sample participants were purposively selected Information Technology experts from various selected State College and Universities. A structured interview as the main instrument of the study investigated threats and challenges of cybersecurity to assess active and proactive approaches to developing a model framework for security resources in respective academic institutions. Responses gathered from the interview were consolidated and analyzed through a thematic coding process. The result of the study revealed the following challenges in cybersecurity are user education, cloud security, information security strategy, and unsecured personal devices. The creation of a program logic model will provide an informed cybersecurity planning, implementation, and assessment framework to the commission on higher education in collaboration with the Department of Information and Communication Technology, and the Philippine Association of the State Colleges and Universities

The Loschmidt Echo as a robust decoherence quantifier for many-body systems

We employ the Loschmidt Echo, i.e. the signal recovered after the reversal of an evolution, to identify and quantify the processes contributing to decoherence. This procedure, which has been extensively used in single particle physics, is here employed in a spin ladder. The isolated chains have 1/2 spins with XY interaction and their excitations would sustain a one-body like propagation. One of them constitutes the controlled system S whose reversible dynamics is degraded by the weak coupling with the uncontrolled second chain, i.e. the environment E. The perturbative SE coupling is swept through arbitrary combinations of XY and Ising like interactions, that contain the standard Heisenberg and dipolar ones. Different time regimes are identified for the Loschmidt Echo dynamics in this perturbative configuration. In particular, the exponential decay scales as a Fermi golden rule, where the contributions of the different SE terms are individually evaluated and analyzed. Comparisons with previous analytical and numerical evaluations of decoherence based on the attenuation of specific interferences, show that the Loschmidt Echo is an advantageous decoherence quantifier at any time, regardless of the S internal dynamics.Comment: 12 pages, 6 figure

Integrated early warning surveillance. Achilles′ heel of one health?

Emerging and re-emerging infectious diseases and zoonoses indicate the importance of the One Health (OH) approach for early warning. At present, even when surveillance data are available, they are infrequently timeously shared between the health sectors. In the context of the MediLabSecure (MLS) Project, we investigated the collection of a set of surveillance indicators able to provide data for the implementation of integrated early warning systems in the 22 MLS countries of the Mediterranean, Black Sea and Sahel regions. We used an online questionnaire (covering vector, human, and animal sectors), focusing on seven relevant arboviruses, that was submitted to 110 officially appointed experts. Results showed that West Nile virus was perceived as the most relevant zoonotic pathogen, while Dengue virus was the most relevant non-zoonotic pathogen in the study area. Data collection of early warning indicators is in place at a different level for all the investigated pathogens and in almost all the MLS Countries. Further assessments on the reliability of the collection in place and on the feasibility of piloting an integrated early warning system for arbovirus could verify if integrated early warning really represents the Achilles’ heel of OH
