Marketing A Hospitality Program And Its Product
No full textIn his dialogue entitled - Marketing A Hospitality Program and Its Product - Jürgen Chopard, Dr. es Sciences (Economics) Director, Centre International de Glion, Glion, Switzerland, Dr. Chopard initially offers: “The recruitment of qualified personnel is extremely difficult in an industry with a poor image; where career paths are not well defined. The author discusses the employment of marketing management techniques to improve the positioning of hospitality education and create a more attractive perception of the hotel industry.”
As outlined in the above paragraph, Dr. Chopard vectors-in on marketing strategies from two standpoints; the educational side with its focus on curriculum, and the larger, industry side with its emphasis on public perception and service. These are not necessarily, nor should they be viewed as disparate elements.
“ Although some professionals may see schools of hospitality education catering to two markets, students on one hand and industry on the other, in fact, their needs should be viewed as the same and hence a single market,” Dr. Chopard says to bolster his assertion.
“The marketing concept is a management orientation that holds that the key task of the organization is to determine the needs and wants of target markets and to adapt the organization to delivering the desired satisfactions more effectively and efficiently than its competitor,” the author confides, with an attribution.
From these information/definition leanings, Dr. Chopard continues on a path that promotes the Centre International de Glion, Glion, Switzerland, which he is affiliated with. Why, because they endorse the same principles he is explaining to you. That’s not a bad thing.
Essentially, what Dr. Chopard wants you to know is, education and business management are synonymous and therefore should share the same marketing designs and goals.
“It is hard to believe that as critically important a sector as education does not use for its own management the techniques which it teaches and which have largely been proved in other fields,” the author provides as counterpoint.
Since pedagogical needs so closely relate to the more pragmatic needs of the industry in general, these elements should seek to compliment and engage each other, in fact, collaboration is imperative, Dr. Chopard expresses a priori.
“The cooperation of future employers is indispensable in the preparation of the product, so that it is capable of providing the expected services. The need for close relations between training establishments and the hotel and catering industry seems obvious,” Dr. Chopard says.
The author reveals some flaws in hospitality marketing strategy, and then contrasts these against how a successful strategy could/should be implemented
Thespoides bolivari Chopard 1916
No full textThespoides bolivari Chopard, 1916 (Figs. 1–2) The actual holotype (Fig. 1) is incomplete, as the mesothorax, metathorax and abdomen are all now missing. The only parts left are the pronotum, both forelegs, and the head, the latter partially damaged. The specimen bears three labels (Fig. 1). The original description of the complete insect was accompanied by three illustrations that are reproduced in Figure 2. After comparing this specimen with the original description and accompanying illustrations, the author was able to draw several conclusions about its identity, as follows: A) The only surviving parts of the type (i.e., the prothorax and head) conform to the original description of T. bolivari. The left foretibia and femur are notoriously smaller than the right ones, a clear sign of a regenerated lost limb; this anatomical feature of the type was not mentioned by Chopard. Analysis of pronotal proportions, armature of the forelegs and general habitus of these parts confirms that the type of T. bolivari is ascribed to Angela guianensis Rehn, 1906 (Table 1), a widespread and frequently collected species throughout the Amazon basin, including localities in Colombia. Consequently, the now missing parts of the type specimen (i.e., the mesothorax, metathorax and abdomen), which were described and illustrated by Chopard (Fig. 2), almost certainly belong to another species, as they depart markedly in form from the anatomy of other Angela spp., including A. guianensis. For example, the cerci in T. bolivari were originally described and illustrated as cylindrical, rather than laminar, the latter a putative synapomorphy of Angela and a character of widespread use in identification keys (e.g. Terra, 1995). Similarly, the wings of T. bolivari were described as “hairy”, a condition not observed in Angela. Accordingly, it is highly likely that the specimen studied by Chopard was a composite specimen comprised of disarticulated body parts from two different species, one of which was A. guianensis (Table 1). This likely explains why the abdomen was markedly shorter than the pronotum. B) Although the posterior thorax and abdomen are now lost, the original description provides clues about the identity of the other species. The wings depicted by Chopard (Fig. 2) exhibit characteristics typical of members of the family Thespidae, such as the vein pattern, the elongated stigma on the forewing and the conspicuous pilosity on the wing surface. Similarly, the triangular supra-anal plate is another feature commonly observed in Thespidae (Fig. 2). Unfortunately, the actual identity of this part of the type cannot be determined based on the description alone, but judging from the metrics provided by Chopard, it likely corresponded to a species of comparable size, such as members of Musonia Saussure, 1869 or Pseudomusonia Werner, 1909. C) The distal margin of the type specimen’s pronotum contains a residue of glue, which provides additional (though circumstantial) evidence that, at one time, the anomalous posterior elements of the specimen were glued to the anterior elements. D) Chopard (1916) assigned Thespoides to the subfamily Miopteryginae, a lineage that today constitutes the family Thespidae. Interestingly, the name Thespoides was inspired from the apparent similarities between the proposed genus and Angela (the species of which were assigned to Thespis at the time of Chopard’s publication). Both Angela and Thespis are now considered valid and distinct genera. These two facts suggest that Chopard himself was confused by the dual nature of the specimen before him, without realizing that it was a composite of non-conspecific, disarticulated parts. Regardless, his classification was based on the thespid traits of the type. Under Article 73.1.2 of the International Code of Zoological Nomenclature (ICZN, 1999) “ if the nominal species-group taxon is based on a single specimen, either so stated or implied in the original publication, that specimen is the holotype fixed by monotypy ”. Chopard described T. bolivari on the basis of a single specimen, citing it simply as the “type”. Chopard clearly considered the whole specimen as a single individual, therefore his procedure conforms to the ICZN and thus this specimen can be considered as the holotype. However, Article 73.1.5 states “ If a subsequent author finds that a holotype which consists of a set of components (e.g. disarticulated body parts) is not derived from an individual animal, the extraneous components may, by appropriate citation, be excluded from the holotype … ”. Thus, in agreement to Article 73.1.5 and to provide nomenclatural stability, the non-conspecific lost parts from the type of T. bolivari, already physically removed from the type, are removed from the description. In addition, Angela guianensis was described by Rehn (1906) ten years before Chopard’s Thespoides bolivari description, making it necessary to apply the “Principle of Priority” (ICZN Article 23.1). Accordingly, it is established that Thespoides bolivari as a new junior synonym of Angela guianensis. A summary of the taxonomy follows: Genus Angela Serville, 1839 = Thespoides Chopard, 1916 n. syn. Angela guianensis Rehn, 1906 = Thespis infuscata Chopard, 1911 = Thespoides bolivari Chopard, 1916 n. syn. In addition, the type of Thespis infuscata Chopard, 1911, also deposited at the MNCN was examined. This species is considered to be a junior synonym of A. guianensis by Giglio-Tos (1927), an action later accepted by Rehn (1935) that is herein corroborated. Because A. guianensis is a rather common species across the Amazon basin, further studies are needed to determine whether or not other synonyms remain to be discovered.Published as part of Rivera, Julio, 2014, On the identity and taxonomic status of the enigmatic mantid Thespoides bolivari Chopard, 1916 (Mantodea: Mantidae, Angelinae), pp. 269-273 in Zootaxa 3797 (1) on pages 269-272, DOI: 10.11646/zootaxa.3797.1.16, http://zenodo.org/record/491546

Cult.Co. Diam. Angola 56: 37. Paraloxoblemmus angulifrons Chopard, 1967. Orth. Cat. 10: 131. The following description translated from Chopard (1951). The author provides the photos of type in NHMLA. This species is rather large in size. Coloration light brown, shiny. Head as wide as pronotum; occiput with 6 yellow short straight stripes, Frontorostrum very long, oblique ventrally, lateral margins straight, convergent, round at apex; a distinct ridge between vertex and rostrum. Face elongate, oblique, feebly concave in lateral aspect. Pronotum wider than long in mid line about 1.5: 1, very slightly wider near apex than at base; anterior margin slightly concave, posterior margin straight, dorsal surface of disc feebly convex, glabrous, light brown, median furrow with yellow stripe; lateral tear-drop markings yellow, fine hairy, covered with brown dots; lateral lobes of pronotum with ventral margin straight, anterior angle rounded, dorsally half brown, ventrally half yellow. Abdomen and cerci brown; subgenital plate large, apical portion with a small carina. Genitalia minute; epiphallus short, truncate at apex (in this respect it is similar to Gryllus domesticus), ventral parts rounded, extremely short, not exceeding the epiphallus in length. Legs brown, relatively short and robust, brown, covering with fine hairs. Fore tibia with large tympanum ovate in outer side, apex with 2 spines; tarsi short; metatarsus less than half the length of other segments, dorsal surface with 2 rows of spines. Middle legs similar to fore legs, longer than fore legs; middle tibia with 4 apical spurs. Hind tibia with long and strong spines, weakly movable, i/o= 7 / 8; ventral apical spurs very long; median spurs slightly longer than dorsal spur and reaching to half of metatarsus; armed with teeth i/o = 1 /7, 2 apical spurs. Tegmen reaching at abdominal segment V, round at apex; anal area very short; mirror oblique quadrate, with one short dividing vein; diagonal vein rather long, straight; chordal veins slightly curved inward, external pair parallel to one another; 2 oblique veins; apical portion very short, reduced to 2 rows of small cells. Wing absent. Specimen examined. 1 male, Repub. Peop. Congo: Lae, Likouala R. Nov. 1981; H. A. Regustens. (Fig 2) The specimen from Los Angeles County Museum was dissected for genitalic examination. (Fig. 2 D). Measurements (in mm): Body length: 26.0. Tegmen length: 10.0. Tegmen width: 10.0. Head length: 10.0. Head width: 6.0. Distance between antennae: 2.0. Distance between eyes: 2.5. Pronotum length: 11.0. Length of hind femora: 21.0. Width of hind femora: 5.0. Length of cerci: 20.0. Karny (1907) measurements as follows (in mm): Body length: 25.0. Frontorostrum: 5.0. Pronotum length: 4.0. Hind femur: 12.8. Hind tibia: 10.0. Tegmen: 7.6. This species seems to be related to Paraloxoblemmus loxoblemmoides Karny, from Sudan. It is different from in its larger size, frontorostrum much more rounded at apex and the tegmina shorter and more blunt. According to Karny (1907) the frontorostrum of Paraloxoblemmus loxoblemmoides is longer than this species (1.9–3.4 mm). Unfortunately, Karny (1907) did not note the condition of the hind tibia spur. Despite this, it seems to be related to Asiatic Loxoblemmus. Distribution.

PMID: 27066967International audienceHIV-1 Tat is efficiently secreted by HIV-1 infected or Tat-transfected cells. Accordingly, Tat concentrations in the nanomolar range have been measured in the sera of HIV-1 infected patients, and this protein acts as a viral toxin on bystander cells. Nevertheless, assaying Tat concentration in media or sera is not that straightforward because extracellular Tat is unstable and particularly sensitive to oxidation. Moreover, most anti-Tat antibodies display limited affinity. Here, we describe methods to quantify extracellular Tat using a sandwich ELISA or Western blotting when Tat is secreted by suspension or adherent cells, respectively. In both cases it is important to capture exported Tat using antibodies before any Tat oxidation occurs otherwise it will become denatured and unreactive toward antibodies
« Ex post » vs « Ex ante » : le cas de l’économie du droit de la faillite
No full textBankruptcy law : justification and reform
This article deals with the Law and Economics approach of bankruptcy law. The author presents this field of research in two parts. First, he studies the conditions of ex post efficiency in the sense that stakeholders select the issue which maximizes the value of the financially distressed firm. In other words, the author justifies the existence of bankruptcy rules as a way of coordinating stakeholders on the optimal issue. Second, he studies the impact of bankruptcy rules on debtors’ and creditors’ ex ante behaviours, that is to say before the financial distress. At this time, he considers both alternative models of bankruptcy resolution and the impact of current bankruptcy rules on stakeholders’ strategies. Based on these new considerations, the author tries to explain the diversity of various national bankruptcy systems.
JEL Classification : G33, K29Cet article offre une revue de la littérature en économie du droit de la faillite. L’auteur montre comment l’économiste appréhende ce droit particulier et traite la question de son efficacité ex post et de son efficacité ex ante. Dans le premier cas, il juge le droit de la faillite au vu du critère de la maximisation de la valeur de l’entreprise en difficulté. Dans le second cas, l’auteur étudie comment l’économiste analyse les règles de droit par le prisme des effets qu’elles devraient normalement produire, notamment des incitations sur le comportement du débiteur et des créanciers. Il aborde, en particulier, les problèmes liés à la dissimulation des difficultés financières, à l’effort des dirigeants déterminant le résultat de l’entreprise, à la prise de risque ou aux stratégies d’enracinement des dirigeants. Enfin, l’auteur discute également l’hypothèse selon laquelle la diversité des codes de la faillite nationaux serait liée aux différences entre les systèmes financiers des pays.
