The island of Kauai, Hawaii's progressive shoreline setback and coastal protection ordinance

Approximately two-thirds of coastal and Great Lakes states have some type of shoreline construction setback or construction control line requiring development to be a certain distance from the shoreline or other coastal feature (OCRM, 2008). Nineteen of 30 coastal states currently use erosion rates for new construction close to the shoreline. Seven states established setback distances based on expected years from the shoreline: the remainder specify a fixed setback distance (Heinz Report, 2000). Following public hearings by the County of Kauai Planning Commission and Kauai County Council, the ‘Shoreline Setback and Coastal Protection Ordinance’ was signed by the Mayor of Kauai on January 25, 2008. After a year of experience implementing this progressive, balanced shoreline setback ordinance several amendments were recently incorporated into the Ordinance (#887; Bill #2319 Draft 3). The Kauai Planning Department is presently drafting several more amendments to improve the effectiveness of the Ordinance. The intent of shoreline setbacks is to establish a buffer zone to protect shorefront development from loss due to coastal erosion - for a period of time; to provide protection from storm waves; to allow the natural dynamic cycles of erosion and accretion of beaches and dunes to occur; to maintain beach and dune habitat; and, to maintain lateral beach access and open space for the enjoyment of the natural shoreline environment. In addition, a primary goal of the Kauai setback ordinance is to avoid armoring or hardening of the shore which along eroding coasts has been documented to ultimately eliminate the fronting beach.

An economic approach to consumer product ratings

In three essays we examine user-generated product ratings with aggregation. While recommendation systems have been studied extensively, this simple type of recommendation system has been neglected, despite its prevalence in the field. We develop a novel theoretical model of user-generated ratings. This model improves upon previous work in three ways: it considers rational agents and allows them to abstain from rating when rating is costly; it incorporates rating aggregation (such as averaging ratings); and it considers the effect on rating strategies of multiple simultaneous raters. In the first essay we provide a partial characterization of equilibrium behavior. In the second essay we test this theoretical model in laboratory, and in the third we apply established behavioral models to the data generated in the lab. This study provides clues to the prevalence of extreme-valued ratings in field implementations. We show theoretically that in equilibrium, ratings distributions do not represent the value distributions of sincere ratings. Indeed, we show that if rating strategies follow a set of regularity conditions, then in equilibrium the rate at which players participate is increasing in the extremity of agents' valuations of the product. This theoretical prediction is realized in the lab. We also find that human subjects show a disproportionate predilection for sincere rating, and that when they do send insincere ratings, they are almost always in the direction of exaggeration. Both sincere and exaggerated ratings occur with great frequency despite the fact that such rating strategies are not in subjects' best interest. We therefore apply the behavioral concepts of quantal response equilibrium (QRE) and cursed equilibrium (CE) to the experimental data. Together, these theories explain the data significantly better than does a theory of rational, Bayesian behavior -- accurately predicting key comparative statics. However, the theories fail to predict the high rates of sincerity, and it is clear that a better theory is needed.

Assessment of consumer acceptance of kilishi of African carp (Labeo coubie Rueppell) and Elephant snout (Hyperopisus bebe occidentalis, Guenther)

This study was carried out to assess consumers' acceptance of kilishi prepared from Labeo coubie and Hyperopisus bebe occidentalis in Sokoto. The organoleptic properties (texture, odour, taste and flavour) of kilishi in its fresh form and under storage for 16 weeks were determined. The mean scores for the organoleptic assessment (6.90 and 7.19 for kilishi of Labeo and Hyperopisus respectively) showed that fish kilishi was highly acceptable. Hyperopisus kilishi recorded slightly higher mean scores for the tested organoleptic properties. The declining pattern of the sensory assessment scores with length of storage indicated that the optimum storage period under the room temperature for kilishi made from the experimental fish species in the study area was 6-8 weeks. Further research on appropriate storage methods is desirable. However, preparation of fish kilishi could be explored as alternative preservation technique to reduce fish spoilage especially during the glut in supply and to diversify fish products

Statutory protection of freshwater flora and fauna

The aim of this paper is to summarize the present legislation aimed at protecting freshwater species in Britain, and briefly to review its effectiveness. Some areas have been deliberately omitted, such as fisheries legislation designed to conserve stocks, and the statutory protection of birds associated with fresh waters which forms a large subject area in its own right.

The promoter of cell growth- and RNA protection-associated SND1 gene is activated by endoplasmic reticulum stress in human hepatoma cells

Background: Staphyloccocal nuclease domain-containing protein 1 (SND1) is involved in the regulation of gene expression and RNA protection. While numerous studies have established that SND1 protein expression is modulated by cellular stresses associated with tumor growth, hypoxia, inflammation, heat- shock and oxidative conditions, little is known about the factors responsible for SND1 expression. Here, we have approached this question by analyzing the transcriptional response of human SND1 gene to pharmacological endoplasmic reticulum (ER) stress in liver cancer cells. Results: We provide first evidence that SND1 promoter activity is increased in human liver cancer cells upon exposure to thapsigargin or tunicamycin or by ectopic expression of ATF6, a crucial transcription factor in the unfolded protein response triggered by ER stress. Deletion analysis of the 5'-flanking region of SND1 promoter identified maximal activation in fragment (-934, +221), which contains most of the predicted ER stress response elements in proximal promoter. Quantitative real- time PCR revealed a near 3 fold increase in SND1 mRNA expression by either of the stress- inducers; whereas SND1 protein was maximally upregulated (3.4-fold) in cells exposed to tunicamycin, a protein glycosylation inhibitor. Conclusion: Promoter activity of the cell growth- and RNA-protection associated SND1 gene is up-regulated by ER stress in human hepatoma cells.

Lançamentos imobiliários na Freguesia: consumo da habitação na hipermodernidade. O marketing do discurso verde de do lazer

A Freguesia de Jacarepaguá, do Rio de Janeiro, nos últimos cinco anos recebeu mais de 80 lançamentos. Juntamente com a Barra da Tijuca, vem sendo um dos principais alvos do mercado imobiliário carioca, correspondendo a 95% das construções da cidade. Tornou-se bairro na década de 1980. Nas últimas décadas, tem sido foco de expansão urbana. Foi escolhida como espaço privilegiado para a análise das construções e práticas discursivas do mercado imobiliário. O objetivo foi entender o processo de comercialização e lançamento das habitações. Anúncios e materiais de propaganda de 52 empreendimentos permitiram identificar 21 grupos de discursos, ancorados em enunciados e imagens do verde, de famílias felizes e inúmeros itens de lazer que se constituíram em objetos de análise. Novos conceitos e produtos habitacionais são postos no mercado com o uso de inúmeras táticas e estratégias, embasadas no imaginário carioca do verde local e no ideário da casa própria. O marketing dos discursos é utilizado como produtor de sentido sobre o consumidor, sujeito urbano hipermoderno, desejoso de segurança, maior qualidade de vida, sustentabilidade, novos luxos e facilidades a sua disposição. O discurso sedutor é voltado para uma sociedade de consumo, onde inovações mercadológicas, crescentes facilidades financeiras e de crédito fomentam e retroalimentam o desejo e o sonho da casa própria. O crescente número de unidades lançadas estimula a concorrência, assume o posto de investimento lucrativo e fomenta a lógica de uma economia neoliberal. Paradoxalmente, destrói a casa-oïkos planetária. A nova habitação ganha itens ecoeficientes, certificações ecológicas e itens de entretenimento, serviços e lazer que extrapolam as necessidades básicas de abrigo e proteção para atingir o encantamento e o novo status do público alvo: o consumidor da classe média. Surgem novos conceitos de moradia, spas, clubes e boutiques. O mundo urbano é transportado para dentro dos muros. O espaço da habitação ganha inúmeros atributos de distinção e consumo. Desta forma, o produto habitação assume definitivamente a categoria de bem de consumo.

O domínio público no direito autoral brasileiro estrutura e função

O estudo do domínio público no direito autoral não se resume a analisar os prazos de proteção conferido às obras intelectuais. De tratamento escasso pela doutrina, o tema é bem mais complexo do que aparenta em um primeiro momento, abrangendo diversas áreas do direito e tendo implicações diretas na vida da sociedade. Uma vez que o direito autoral é composto de dois feixes distintos de direitos o patrimonial e o moral compreender o domínio público é, em primeiro lugar, determinar que efeitos decorrem do ingresso de determinada obra em domínio público quanto a cada um de tais grupos de direitos. Além disso, o impacto do domínio público se faz sentir em outras áreas jurídicas, como direito contratual, direito de propriedade, direito do consumidor, direito de família, direito das sucessões. Sem contar com a relação inevitável a aspectos econômicos e sociais relacionados ao uso de obras em domínio público.Esta tese procura determinar a estrutura jurídica do domínio público no direito autoral brasileiro a partir das leis atualmente em vigor, bem como traçar a função do instituto, a fim de dar ao domínio público a importância devida e estimular o desenvolvimento sócio-cultural do país.

Changes in consumer tastes in the demand for fish and meat in Malaysia

In this article the demand for fish and its substitute was estimated using a very flexible demand function, the Almost Ideal Demand System (AIDS) developed by Deaton and Muelllbaeur (1980), incorporating the habit formation variable to measure the impact of the changes in tastes in comsumer demand for fish and meat products from 1960 to 1990 in Malaysia. Information on price and income elasticities for these meat groups was also obtained. To incorporate consumption habit variables, the dynamic translating procedure proposed by Pollak (1970) and Pollak and Wales (1981) has been adopted. The overall results of the maximum likelihood estimates of the dynamic AIDS model are quite good where 19 of 30 coefficients are significantly different from zero and the minimum budget shares, the constant, are between zero and one for each meat type. Consumers tend to purchase and consume fish, chicken, and pork almost daily. Beef and mutton are only consumed occassionally since they are relatively more expensive. This finding is consistent with the trend observed in the per capita consumption and budget share where fish, chicken, and pork tended to dominate over beef and mutton from 1960 to 1990.
