The Sense and Nonsense of Criminalizing Transfers of Obscene

The recent distribution of nude photos of a number of high profile Hong Kong celebrities has provoked intense discussion about the state of Hong Kong's obscenity and indecency laws. In this paper, I argue that Hong Kong's laws prohibiting the transfer of obscene and indecent information and images between consenting adults are both under-inclusive and over-inclusive. The Control of Obscene and Indecent Articles Ordinance is under-inclusive in that it does not adequately criminalise grave violations of privacy. It is also over-inclusive because it is a blanket prohibition against the transfer by all parties (including consenting adults) of all forms of obscene and indecent materials. The laws unnecessarily violate the free expression rights of both the producer and consenting viewer of the offensive materials. The producer/publisher of such materials does not harm his or her audience as they willingly view such materials. The justification for maintaining a blanket prohibition against all transfers of such materials is invalid and utterly and totally out of touch with modern life in Hong Kong. The proponents of such laws have used Victorian positive morality considerations to justify continued criminalisation. These laws should be abrogated and replaced with a new piece of legislation that is narrowly tailored to deal with those types of offensive displays that are wrongful in a critical rather than a mere positive morality sense. Criminalisation should be limited to those offences that target children or use children in the production process, violate the rights of non-consenting adult audiences not to receive certain intimate information in certain public contexts, and violate privacy rights by publishing a person's private and intimate information without consent. If x obtains y's profoundly private information and publishes it without y's consent, then x violates y's privacy rights in a grave way. The violation in the right circumstances will justify a criminal law response rather than a mere civil law response. Similarly, if x and y copulate on a public bus they subject the captive audience to an offensive display which violates the non-consenting audience's right not to receive certain intimate information. I argue below that these types of privacy violations give the lawmaker a legitimate justification for invoking the criminal law

Noninvasive Techniques in the Evaluation of Arterial Disease

This paper reviews noninvasive technology currently being applied in clinical peripheral vascular laboratories for the evaluation of obstructive arterial disease in the lower extremities and in the cerebral circulation. Lower extremity, arterial insufficiency can be assessed by pressures measured with a Doppler flowmeter or by oscillometric tracings obtained with a Pulse Volume Recorder. Carotid artery stenosis is studied by: 1) ocular pneumoplethysmography, which indirectly measures ophthalmic artery pressure; 2) oculoplethysmography, which compares pulse arrival time at the two eyes; and 3) the Doppler ophthalmic test, which detects the flow pattern in the ophthalmic artery. The main uses of the tests are to evaluate asymptomatic carotid murmurs, to screen high risk groups, and to aid postoperative follow-up

Nondestructive Electromagnetic Material Characterization using a Dual Waveguide Probe: A Full Wave Solution

A nondestructive technique for determining the complex permittivity and permeability of a perfect electric conductor backed magnetic shielding material using a dual waveguide probe is presented. The dual waveguide probe allows for the simultaneous collection of reflection and transmission coefficients which distinguishes it from single probe methods common in the literature. Theoretical development of these coefficients, which is accomplished through a coupled magnetic field integral equations formulation using Love\u27s equivalence principle and solved via the method of moments (MOM), is discussed. Evaluation of the resulting MOM impedance matrix elements is performed using complex plane integration leading to enhanced computational efficiency and physical insight. Comparison of the theoretical and measured reflection and transmission coefficients using a root finding algorithm leads to the desired permittivity and permeability. Measurement results of a magnetic shielding material are presented and compared to traditional methods for the purpose of validating the new technique. The probe\u27s sensitivity to aperture alignment, sample thickness, and flange thickness is also investigated.Abstract © AGU

Nearest-Neighbor-Atom Core-Hole Transfer in Isolated Molecules

A new phenomenon sensitive only to next-door-neighbor atoms in isolated molecules is demonstrated using angle-resolved photoemission of site-selective core electrons. Evidence for this interatomic core-to-core electron interaction is observable only by measuring nondipolar angular distributions of photoelectrons. In essence, the phenomenon acts as a very fine atomic-scale sensor of nearest-neighbor elemental identity

ROTATIONAL-DYNAMICS OF SOLID C-70 - A NEUTRON-SCATTERING STUDY

PMID: 10011126PMID: 10011126 This work at the University of Sussex at supported by the Science and Engineering Research Council, U.K.PMID: 10011126 This work at the University of Sussex at supported by the Science and Engineering Research Council, U.K.PMID: 10011126 This work at the University of Sussex at supported by the Science and Engineering Research Council, U.K.We report the results of neutron-diffraction and low-energy neutron-inelastic-scattering experiments on high-purity solid C-70 between 10 and 640 K. Thermal hysteresis effects are found to accompany structural changes both on cooling and on heating. The observed diffuse scattering intensity does not change with temperature. At 10 K broad librational peaks are observed at 1.82(16) meV [full width at half maximum=1.8(5) meV]. The peaks soften and broaden further with increasing temperature. At and above room temperature, they collapse into a single quasielastic line. At 300 K, the diffusive reorientational motion appears to be somewhat anisotropic, becoming less so with increasing temperature. An isotropic rotational diffusion model, in which the motions of adjacent molecules are uncorrelated, describes well the results at 525 K. The temperature dependence of the rotational diffusion constants is consistent with a thermally activated process having an activation energy of 32(7) meV.This work at the University of Sussex at supported by the Science and Engineering Research Council, U.K

Perspectives on Extended-Release Naltrexone Induction among Patients Living with HIV and Opioid Use Disorder: A Qualitative Analysis

BACKGROUND: The CHOICES study randomized participants with HIV and opioid use disorder (OUD) to HIV clinic-based extended-release naltrexone (XR-NTX), which requires complete cessation of opioid use, versus treatment-as-usual (i.e., buprenorphine, methadone). Study participants randomized to XR-NTX were interviewed to assess their experiences with successful and unsuccessful XR-NTX induction. METHODS: Semi-structured qualitative interviews were completed with a convenience sample of study participants with HIV and OUD (n = 37) randomized to XR-NTX in five HIV clinics between 2018 and 2019. All participants approached agreed to be interviewed. Interviews were digitally recorded, professionally transcribed, and analyzed using thematic analysis. RESULTS: Participants included women (43%), African Americans (62%) and Hispanics (16%), between 27 to 69 years of age. Individuals who completed XR-NTX induction (n = 20) reported experiencing (1) readiness for change, (2) a supportive environment during withdrawal including comfort medications, and (3) caring interactions with staff. Four contrasting themes emerged among participants (n = 17) who did not complete induction: (1) concern and anxiety about withdrawal including past negative experiences, (2) ambivalence about or reluctance to stop opioids, (3) concerns about XR-NTX effects, and (4) preferences for other medications. CONCLUSIONS: The results highlight opportunities to improve initiation of XR-NTX in high-need groups. Addressing expectations regarding induction may enhance XR-NTX initiation rates.

Epigenetic Tailoring for the Production of Anti-Infective Cytosporones from the Marine Fungus Leucostoma persoonii

Recent genomic studies have demonstrated that fungi can possess gene clusters encoding for the production of previously unobserved secondary metabolites. Activation of these attenuated or silenced genes to obtain either improved titers of known compounds or new ones altogether has been a subject of considerable interest. In our efforts to discover new chemotypes that are effective against infectious diseases, including malaria and methicillin-resistant Staphylococcus aureus (MRSA), we have isolated a strain of marine fungus, Leucostoma persoonii, that produces bioactive cytosporones. Epigenetic modifiers employed to activate secondary metabolite genes resulted in enhanced production of known cytosporones B (1, 360%), C (2, 580%) and E (3, 890%), as well as the production of the previously undescribed cytosporone R (4). Cytosporone E was the most bioactive, displaying an IC90 of 13 µM toward Plasmodium falciparum, with A549 cytotoxicity IC90 of 437 µM, representing a 90% inhibition therapeutic index (TI90 = IC90 A459/IC90 P. falciparum) of 33. In addition, cytosporone E was active against MRSA with a minimal inhibitory concentration (MIC) of 72 µM and inhibition of MRSA biofilm at roughly half that value (minimum biofilm eradication counts, MBEC90, was found to be 39 µM)
