The Chef In Society: Origins And Development

In his discourse - The Chef In Society: Origins And Development - Marcel R. Escoffier, Graduate Student, School of Hospitality Management at Florida International University, initially offers: “The role of the modern professional chef has its origins in ancient Greece. The author traces that history and looks at the evolution of the executive chef as a manager and administrator.” “Chefs, as tradespersons, can trace their origins to ancient Greece,” the author offers with citation. “Most were slaves…” he also informs you. Even at that low estate in life, the chef was master of the slaves and servants who were at close hand in the environment in which they worked. “In Athens, a cook was the master of all the household slaves…” says Escoffier. As Athenian influence wanes and Roman civilization picks-up the torch, chefs maintain and increase their status as important tradesmen in society. “Here the first professional societies of cooks were formed, almost a hierarchy,” Escoffier again cites the information. “It was in Rome that cooks established their first academy: Colleqium Coquorum,” he further reports. Chefs, again, increase their significance during the following Italian Renaissance as the scope of their influence widens. “…it is an historical fact that the marriage of Henry IV and Catherine de Medici introduced France to the culinary wonders of the Italian Renaissance,” Escoffier enlightens you. “Certainly the professional chef in France became more sophisticated and more highly regarded by society after the introduction of the Italian cooking concepts.” The author wants you to know that by this time cookbooks are already making important inroads and contributing to the history of cooking above and beyond their obvious informational status. Outside of the apparent European influences in cooking, Escoffier also ephemerally mentions the development of Chinese and Indian chefs. “It is interesting to note that the Chinese, held by at least one theory as the progenitors of most of the culinary heritage, never developed a high esteem for the position of chef,” Escoffier maintains the historical tack. “It was not until the middle 18th Century that the first professional chef went public. Until that time, only the great houses of the nobility could afford to maintain a chef,” Escoffier notes. This private-to-public transition, in conjunction with culinary writing are benchmarks for the profession. Chefs now establish authority and eminence. The remainder of the article devotes itself to the development of the professional chef; especially the melding of two seminal figures in the culinary arts, Cesar Ritz and August Escoffier. The works of Frederick Taylor are also highlighted.

Food Service Operations in the Cruise Industry

Food service on a cruise ship presents some unique challenges. A review of food service in the cruise industry is presented along with some ideas on the future. The case is made for a change in traditional operations with a move toward greater use of computer-driven management techniques.

The Travel Industry: What's in a Name?

The travel and tourism industry is enormous in both size and importance. There can be little doubt that the field is striving to accommodate the diversity of opinion concerning what the industry is and how it can be improved and enlarged even further. Resistance to critiquing long-held beliefs about the industry may inhibit its future. Deconstruction, a postmodern method of analysis, is proposed as one tool with which to engage in reflection upon what the industry is and where it may be headed.

Tourism: Who Needs It?

Is tourism economically beneficial? If so, who benefits? How much of the money generated through tourism can be channeled into other projects so desperately needed by the community without harming the local tour market? Will tourism continue to grow forever, or is there an end in sight? The authors discuss how tourism will change in approaching the next century: and how people will change if tourism is to remain such an important economic facto

Yield Management: Where We've Been, Where We Are, Where We're Going

The author describes yield management and the technology used to implement yield management in hotels, issues in usefulness, and legal issues concerning the use of yield management. A look into the future is provided, along with a critique of what further research may be needed in order to raise the level of usefulness of yield management systems in the hotel industry to that found in the airlines.

In My Opinion… Good Intentions Don't Count

While simple guest surveys can be poorly constructed with little negative consequences, often surveys are used in making important policy decisions. Researchers and policy makers must carefully construct their research instruments in order to avoid biases which may result in muddled or incorrect responses. The authors review the process of creating, administering, and analyzing surveys with an eye toward reducing survey bias to a minimum. Reliable results require a rigorous and careful approach when creating and using instruments.

Coppicing shifts CO2 stimulation of poplar productivity to above-ground pools: a synthesis of leaf to stand level results from the POP/EUROFACE experiment

A poplar short rotation coppice (SRC) grown for the production of bioenergy can combine carbon (C) storage with fossil fuel substitution. Here, we summarize the responses of a poplar (Populus) plantation to 6 yr of free air CO2 enrichment (POP/EUROFACE consisting of two rotation cycles). We show that a poplar plantation growing in nonlimiting light, nutrient and water conditions will significantly increase its productivity in elevated CO2 concentrations ([CO2]). Increased biomass yield resulted from an early growth enhancement and photosynthesis did not acclimate to elevated [CO2]. Sufficient nutrient availability, increased nitrogen use efficiency (NUE) and the large sink capacity of poplars contributed to the sustained increase in C uptake over 6 yr. Additional C taken up in high [CO2] was mainly invested into woody biomass pools. Coppicing increased yield by 66% and partly shifted the extra C uptake in elevated [CO2] to above-ground pools, as fine root biomass declined and its [CO2] stimulation disappeared. Mineral soil C increased equally in ambient and elevated [CO2] during the 6 yr experiment. However, elevated [CO2] increased the stabilization of C in the mineral soil. Increased productivity of a poplar SRC in elevated [CO2] may allow shorter rotation cycles, enhancing the viability of SRC for biofuel production.

Oligosarcus perdido (Characiformes, Characidae), a new species of freshwater fish from Serra da Bodoquena, upper Rio Paraguai basin, Brazil

Oligosarcus perdido, a new species of freshwater fish from Serra da Bodoquena, upper Rio Paraguai basin, Brazil, is described. The new species is distinguished from congeners by the number of lateral-line scales, number of scales around the caudal peduncle, and osteological characters. The osteology of this new species is also documented by stereomicroscopic photography of cleared and stained specimens. Ecological notes based on direct observation by scuba diving in the field are also provided. Copyright © 2007 Magnolia Press.

A New Diminutive Species of Loricaria (Siluriformes: Loricariidae) from the Rio Paraguay System, Mato Grosso do Sul, Brazil

Loricaria coximensis. new species, is described from the Rio Paraguay basin, in Mato Grosso do Sul State, Brazil. It is distinguished from all other species of Loricaria, except L. holmbergi, L. lundbergi, L. parnahybae, and L. pumila by having abdominal plates confined to the pre-anal shield and posterior median abdominal area, usually loosely joined or separated by naked areas, pectoral girdle mostly naked, with isolated plates near base of pectoral fins and posterior to gill opening vs. abdominal plates well developed and tightly arranged across the entire median abdominal area, including the pectoral girdle. It is distinguished from these other four species by meristic counts and several morphometric proportions, particularly a broader head (19.4-21.3% SL vs. 14.1-19.1% SL). Loricaria coximensis becomes the third described paedomorphic species of Loricaria, along with L. nickeriensis and L. pumila, based on its small adult size (<100 mm SL), reduced number of lateral dermal plates, and incomplete abdominal plate development. The new species is presently known only from a limited section of the Rio Coxim, which has been severely impacted by a hydroelectric dam and widespread conversion of land for agriculture.

Recurrent rearrangements of chromosome 1q21.1 and variable pediatric phenotypes

BACKGROUND: Duplications and deletions in the human genome can cause disease or predispose persons to disease. Advances in technologies to detect these changes allow for the routine identification of submicroscopic imbalances in large numbers of patients. METHODS: We tested for the presence of microdeletions and microduplications at a specific region of chromosome 1q21.1 in two groups of patients with unexplained mental retardation, autism, or congenital anomalies and in unaffected persons. RESULTS: We identified 25 persons with a recurrent 1.35-Mb deletion within 1q21.1 from screening 5218 patients. The microdeletions had arisen de novo in eight patients, were inherited from a mildly affected parent in three patients, were inherited from an apparently unaffected parent in six patients, and were of unknown inheritance in eight patients. The deletion was absent in a series of 4737 control persons (P=1.1x10(-7)). We found considerable variability in the level of phenotypic expression of the microdeletion; phenotypes included mild-to-moderate mental retardation, microcephaly, cardiac abnormalities, and cataracts. The reciprocal duplication was enriched in nine children with mental retardation or autism spectrum disorder and other variable features (P=0.02). We identified three deletions and three duplications of the 1q21.1 region in an independent sample of 788 patients with mental retardation and congenital anomalies. CONCLUSIONS: We have identified recurrent molecular lesions that elude syndromic classification and whose disease manifestations must be considered in a broader context of development as opposed to being assigned to a specific disease. Clinical diagnosis in patients with these lesions may be most readily achieved on the basis of genotype rather than phenotype.

Alphaviruses induce apoptosis in Bcl-2-overexpressing cells: evidence for a caspase-mediated, proteolytic inactivation of Bcl-2

Bcl-2 oncogene expression plays a role in the establishment of persistent viral infection by blocking virus-induced apoptosis. This might be achieved by preventing virus-induced activation of caspase-3, an IL-1beta-converting enzyme (ICE)-like cysteine protease that has been implicated in the death effector phase of apoptosis. Contrary to this model, we show that three cell types highly overexpressing functional Bcl-2 displayed caspase-3 activation and underwent apoptosis in response to infection with alphaviruses Semliki Forest and Sindbis as efficiently as vector control counterparts. In all three cell types, overexpressed 26 kDa Bcl-2 was cleaved into a 23 kDa protein. Antibody epitope mapping revealed that cleavage occurred at one or two target sites for caspases within the amino acid region YEWD31 (downward arrow) AGD34 (downward arrow) A, removing the N-terminal BH4 region known to be essential for the death-protective activity of Bcl-2. Preincubation of cells with the caspase inhibitor Z-VAD prevented Bcl-2 cleavage and partially restored the protective activity of Bcl-2 against virus-induced apoptosis. Moreover, a murine Bcl-2 mutant having Asp31, Asp34 and Asp36 substituted by Glu was resistant to proteolytic cleavage and abrogated apoptosis following virus infection. These findings indicate that alphaviruses can trigger a caspase-mediated inactivation of Bcl-2 in order to evade the death protection imposed by this survival factor.

Radiance, irradiance, and remote sensing reflectance during the North Sea Coast Harmful Algal Bloom (NORCOHAB II) HEINCKE cruise HE302

In this study four data quality flags are presented for automated and unmanned above-water hyperspectral optical measurements collected underway in the North Sea, The Minch, Irish Sea and Celtic Sea in April/May 2009. Coincident to these optical measurements a DualDome D12 (Mobotix, Germany) camera system was used to capture sea surface and sky images. The first three flags are based on meteorological conditions, to select erroneous incoming solar irradiance (ES) taken during dusk, dawn, before significant incoming solar radiation could be detected or under rainfall. Furthermore, the relative azimuthal angle of the optical sensors to the sun is used to identify possible sunglint free sea surface zones. A total of 629 spectra remained after applying the meteorological masks (first three flags). Based on this dataset, a fourth flag for sunglint was generated by analysing and evaluating water leaving radiance (LW) and remote sensing reflectance (RRS) spectral behaviour in the presence and absence of sunglint salient in the simultaneously available sea surface images. Spectra conditions satisfying "mean LW (700-950 nm) < 2 mW/m**2/nm/Sr" or alternatively "minimum RRS (700-950 nm) < 0.010/Sr", mask the most measurements affected by sunglint, providing efficient flagging of sunglint in automated quality control. It is confirmed that valid optical measurements can be performed 0° <= theta <= 360° although 90° <= theta <= 135° is recommended.
