Address by Hon. Thomas M. Cooley, and Poem by D. Bethune Duffield, Esq., on the Dedication of the Law Lecture Hall of the Michigan University

A stirring address by Professor Cooley upon the occasion of the dedication of the Law Lecture Hall of the first Law School Building. He begins: Students in the Department of Law: While Michigan was yet a wilderness, only feeling along its borders the advancing tread of civilization, and only hearing here and there the sound of the woodman\u27s axe, the wisdom of American statesmen made provision for the establishment in the territory of a great University...

VALUE CO-CREATION ENHANCING DESTINATION RESILIENCE THROUGH SMARTNESS.

The sustainability and competitive advantage of a destination must be extended to the standard of the resilience within the destination. Tourism, a “complex business ecosystem” must collectively manage their inherent vulnerabilities to crisis and disasters. This paper contributes to tourism literature by demonstrating the potential of smartness to increase destination resilience through value co-creation for all stakeholders through their real time responsiveness to crisis and disasters, ultimately strengthening resilience. Secondary research was conducted using a multi-disciplinary approach to understand the tenets that were key in the development of the core concepts of the research. Value co-creation within tourism has been primarily restricted to the consumer organization relationship. The discussion, however, must be elevated and reflected in the internal destination systems and processes to enhance the traveller experience, safety and security, which, ulimately, is value for all. Value co-creation is one of the inherent elements and outcomes of the Real Time Resilience and augers well for all stakeholders as it capitalizes on smartness to enhance decision making during crisis and disasters

C1 inhibitor deficiency: 2014 United Kingdom consensus document

C1 inhibitor deficiency is a rare disorder manifesting with recurrent attacks of disabling and potentially life-threatening angioedema. Here we present an updated 2014 United Kingdom consensus document for the management of C1 inhibitor-deficient patients, representing a joint venture between the United Kingdom Primary Immunodeficiency Network and Hereditary Angioedema UK. To develop the consensus, we assembled a multi-disciplinary steering group of clinicians, nurses and a patient representative. This steering group first met in 2012, developing a total of 48 recommendations across 11 themes. The statements were distributed to relevant clinicians and a representative group of patients to be scored for agreement on a Likert scale. All 48 statements achieved a high degree of consensus, indicating strong alignment of opinion. The recommendations have evolved significantly since the 2005 document, with particularly notable developments including an improved evidence base to guide dosing and indications for acute treatment, greater emphasis on home therapy for acute attacks and a strong focus on service organisation.

Autocompensating Quantum Cryptography

Quantum cryptographic key distribution (QKD) uses extremely faint light pulses to carry quantum information between two parties (Alice and Bob), allowing them to generate a shared, secret cryptographic key. Autocompensating QKD systems automatically and passively compensate for uncontrolled time dependent variations of the optical fiber properties by coding the information as a differential phase between orthogonally-polarized components of a light pulse sent on a round trip through the fiber, reflected at mid-course using a Faraday mirror. We have built a prototype system based on standard telecom technology that achieves a privacy-amplified bit generation rate of ~1000 bits/s over a 10-km optical fiber link. Quantum cryptography is an example of an application that, by using quantum states of individual particles to represent information, accomplishes a practical task that is impossible using classical means.Comment: 18 pages, 6 figures, 1 table.

The women's movement in Japan and its effect on the workplace

The purpose of this study is to investigate the role of women in the Japanese workplace. Data obtained from in-depth interviews and questionnaires, shows that the Japanese workplace is in a state of change moving toward a higher level of opportunity for female workers. While similar to the circumstances experienced by Western women, the changes which Japanese women are experiencing have their own history and thus are analyzed from a non-Western perspective. Some key aspects of the analysis include: training, separate positions for men and women, tasks, and perceptions of gender discrimination. For men and women who held the same jobs it was found that the majority of training experiences were gender neutral. This is consistent with the fact that Japanese companies must make training equal as mandated by the 1985 Equal Employment Opportunity Law. In the workplace, however, discrimination has taken the form of separate positions for men and women. While there were informants who were both supportive and un-supportive of job separation, it was clear that this practice resulted in lower salaries and fewer high level positions for women. When males and females held the same positions, 17% of women were given different duties. These duties included serving tea, cleaning, and hostessing, all of which are tasks generally done by a wife for her husband. Thus in some instances domestic roles determine tasks assigned in the workplace. From the informants' responses a Japanese definition of gender discrimination was formulated. Culturally, gender discrimination was noted in terms of treating women differently than men, but also included improper sexual advances. A full 80% of the study's informants acknowledged the existence of gender discrimination in the Japanese workplace. Finally, from this sample it was determined that cultural relativism, internal labor market theory, and human capital theory are all compatible tools for analysis of the Japanese labor market

Performance of various quantum key distribution systems using 1.55 um up-conversion single-photon detectors

We compare the performance of various quantum key distribution (QKD) systems using a novel single-photon detector, which combines frequency up-conversion in a periodically poled lithium niobate (PPLN) waveguide and a silicon avalanche photodiode (APD). The comparison is based on the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984 (BB84), the Bennett, Brassard, and Mermin 1992 (BBM92), and the coherent differential phase shift keying (DPSK). We show that the up-conversion detector allows for higher communication rates and longer communication distances than the commonly used InGaAs/InP APD for all the three QKD protocols.Comment: 9 pages, 9 figure

A high-performance integrated single-photon detector for telecom wavelengths

We have integrated a commercial avalanche photodiode (APD) and the circuitry needed to operate it as a single-photon detector (SPD) onto a single PC-board. At temperatures accessible with Peltier coolers (~200-240K), the PCB-SPD achieves high detection efficiency (DE) at 1308 and 1545 nm with low dark count probability (e.g. ~10-6/bias pulse at DE=20%, 220 K), making it useful for quantum key distribution (QKD). The board generates fast bias pulses, cancels noise transients, amplifies the signals, and sends them to an on-board discriminator. A digital blanking circuit suppresses afterpulsing.Comment: (10 pages, 6 figures

Practical quantum key distribution: On the security evaluation with inefficient single-photon detectors

Quantum Key Distribution with the BB84 protocol has been shown to be unconditionally secure even using weak coherent pulses instead of single-photon signals. The distances that can be covered by these methods are limited due to the loss in the quantum channel (e.g. loss in the optical fiber) and in the single-photon counters of the receivers. One can argue that the loss in the detectors cannot be changed by an eavesdropper in order to increase the covered distance. Here we show that the security analysis of this scenario is not as easy as is commonly assumed, since already two-photon processes allow eavesdropping strategies that outperform the known photon-number splitting attack. For this reason there is, so far, no satisfactory security analysis available in the framework of individual attacks.Comment: 11 pages, 6 figures; Abstract and introduction extended, Appendix added, references update

Theory of Spontaneous Polarization of Endohedral Fullerenes

A pseudo-Jahn-Teller model describing central atom distortions is proposed for endohedral fullerenes of the form A@C$_{60}$ where A is either a rare gas or a metal atom. A critical (dimensionless) coupling $g_c$ is found, below which the symmetric configuration is stable and above which inversion symmetry is broken. Vibronic parameters are given for selected endohedral fullerenes.Comment: 4 pages, REVTEX, 1 Postscript figure. [Phys. Rev. Lett. (in press)

Order out of Randomness : Self-Organization Processes in Astrophysics

Self-organization is a property of dissipative nonlinear processes that are governed by an internal driver and a positive feedback mechanism, which creates regular geometric and/or temporal patterns and decreases the entropy, in contrast to random processes. Here we investigate for the first time a comprehensive number of 16 self-organization processes that operate in planetary physics, solar physics, stellar physics, galactic physics, and cosmology. Self-organizing systems create spontaneous {\sl order out of chaos}, during the evolution from an initially disordered system to an ordered stationary system, via quasi-periodic limit-cycle dynamics, harmonic mechanical resonances, or gyromagnetic resonances. The internal driver can be gravity, rotation, thermal pressure, or acceleration of nonthermal particles, while the positive feedback mechanism is often an instability, such as the magneto-rotational instability, the Rayleigh-B\'enard convection instability, turbulence, vortex attraction, magnetic reconnection, plasma condensation, or loss-cone instability. Physical models of astrophysical self-organization processes involve hydrodynamic, MHD, and N-body formulations of Lotka-Volterra equation systems.Comment: 61 pages, 38 Figure
