Homeowners Associations as Private Governments: What We Know,What We Don’t Know,and Why It Matters

Homeowners associations (HOAs) are private governments that are reshaping urban governance and service delivery in large parts of the United States. Despite the fact that millions of Americans are HOA members, the field of public affairs has paid scant attention to these new governance entities. The essays in this symposium call attention to HOAs’ potential effects on urban services and civic life in the hope of sparking interest among scholars and public managers to include HOAs in our understanding, research, and teaching of contemporary urban governance.     

Delegation and Institutional Design in Health‐Care Rationing

The delegation of decision‐making powers to nonmajoritarian, independent agencies has become a significant phenomenon in more and more policy areas. One of these is the health‐care sector, where decisions on the range of services covered within public systems have, in most developed countries, been delegated to specialized bodies. This article offers an analytical framework that seeks to grasp the empirical variety and complexity of delegative processes and appointed institutions. The framework is used to describe decision‐making processes and institutions in six countries: Austria, Germany, Norway, Sweden, New Zealand, and the United Kingdom. We find that, although constrained by preexisting institutional structures and traditions, delegators enjoy a considerable degree of discretion in their institutional design choices and engage in strategic design and redesign of appointed bodies.     

Field testing of collection cards for Cannabis sativa samples with a single hexanucleotide DNA marker

The validity and feasibility of using DNA collection cards in the field for preservation and analysis of Cannabis sativa genotypes were investigated using a highly specific hexanucleotide marker. Collection cards were submitted to the National Marijuana Initiative, which selectively trained and managed the collection of specific types of samples from a variety of participating agencies. Samples collected at seizure sites included fresh marijuana leaf samples, dried "dispensary" samples, U.S. border seizures, and hashish. Using a standardized PCR kit with custom-labeled oligonucleotide primers specific to marijuana, collection cards produced eight genotypes and 13 different alleles, extremely low baselines, and no cross-reactivity with control plant species. Results were produced from all sample types with the exception of hashish. Plant DNA collection cards represent an easily implementable method for the genetic identification and relatedness of C. sativa street and grow site-seized samples with applications for databasing and market disruption.     

Requisites of radical reform: Income maintenance versus tax preferences

Why did tax reform succeed in gaining passage while the family assistance plan failed? Using cultural theory, we argue that the active consent of elites from three political cultures is required before radical policy proposals will win political support in America. Although the Nixon administration cast the income maintenance plan in integrative terms—support for the family—it failed because egalitarian leaders demanded more. Tax reform succeeded because elites of the three cultures—individualists, egalitarians, and supporters of hierarchy—saw benefits in the plan and were willing to compromise.

Evaluation of Raman spectroscopy for the analysis of colored fibers: a collaborative study

A collaborative study on Raman spectroscopy was carried out by members of the ENFSI (European Network of Forensic Science Institutes) European Fibres Group (EFG) on three dyed fibers: two red acrylics and one red wool. Raman instruments from six different manufacturers were tested as well as nine different laser wavelengths ranging from blue (lambda = 458 nm) to near infrared-NIR (lambda = 1064 nm). This represents the largest comparison study of Raman analytical parameters carried out on identical fiber samples. For the chosen fiber and dye samples, red lasers (lambda = 633 and 685 nm) gave the poorest spectral quality whereas blue (458 nm), green (514 nm) and near infrared lasers (785, 830 and 1064 nm) provided average results. Blue (488 nm) and green lasers (532 nm) globally gave the best quality spectra. Fluorescence problems were often encountered with some of the excitation wavelengths and therefore a flexible Raman instrument equipped with different lasers can be recommended to measure forensic fiber samples. The instrument should also be equipped with a Raman microscope in order to be able to focus on a single fiber. This study shows that Raman spectroscopy usually enables the identification of the main dye present in a colored fiber; however, minor dye components are much more difficult to detect. SERRS (Surface Enhanced Resonance Raman Scattering) techniques give an improvement of the dye's spectral intensity but no spectral improvement was observed for the two red acrylic and red wool fibers tested.     

Raman spectroscopy and microspectrophotometry of reactive dyes on cotton fibres: Analysis and detection limits

A collaborative study on Raman spectroscopy and microspectrophotometry (MSP) was carried out by members of the ENFSI (European Network of Forensic Science Institutes) European Fibres Group (EFG) on different dyed cotton fabrics. The detection limits of the two methods were tested on two cotton sets with a dye concentration ranging from 0.5 to 0.005% (w/w). This survey shows that it is possible to detect the presence of dye in fibres with concentrations below that detectable by the traditional methods of light microscopy and microspectrophotometry (MSP). The MSP detection limit for the dyes used in this study was found to be a concentration of 0.5% (w/w). At this concentration, the fibres appear colourless with light microscopy. Raman spectroscopy clearly shows a higher potential to detect concentrations of dyes as low as 0.05% for the yellow dye RY145 and 0.005% for the blue dye RB221. This detection limit was found to depend both on the chemical composition of the dye itself and on the analytical conditions, particularly the laser wavelength. Furthermore, analysis of binary mixtures of dyes showed that while the minor dye was detected at 1.5% (w/w) (30% of the total dye concentration) using microspectrophotometry, it was detected at a level as low as 0.05% (w/w) (10% of the total dye concentration) using Raman spectroscopy. This work also highlights the importance of a flexible Raman instrument equipped with several lasers at different wavelengths for the analysis of dyed fibres. The operator and the set up of the analytical conditions are also of prime importance in order to obtain high quality spectra. Changing the laser wavelength is important to detect different dyes in a mixture.
