Creació d'una discoteca: Amber Club

El món de l’oci nocturn és un món que molta gent disfruta però que ningú acaba de conèixer. Tothom sap per on van els trets principals, però ningú es preocupa profundament per saber realment com funciona, quins són els costos, si els beneficis són elevats, o si és difícil aconseguir que un negoci sigui viable. Aquest, doncs, ha estat el pilar sobre del qual s'ha construït el nostre treball.A través de la creació d’una discoteca i el seu anàlisi cost-benefici hem intentat esbrinar quina és la viabilitat d’un projecte d’aquestes característiques, analitzant tots els costs que s’han d’incórrer, i realitzant un supòsit a la baixa dels ingressos que s’obtindrien.Per dur a terme aquest anàlisi hem realitzat 200 enquestes repartides per les diferents universitats de la província de Barcelona. D’aquesta manera hem pogut analitzar si hi ha demanda per una nova discoteca i quines són les preferències del consumidor.Una vegada fet aquest anàlisi, hem procedit a la recerca d'un local que s'adapti a les nostres necessitats i a les mostrades pel públic enquestat. Al no voler entretenir-nos en qüestions com la decoració del local, o l’adaptació d’aquest a tota la normativa vigent, hem partit del supòsit que un local que actualment funciona estigués disponible pel lloguer, concretament Opium Mar. Hem introduït un seguit de reformes que creiem necessàries pel millor funcionament, i a continuació hem començat amb les estratègies de màrqueting i la determinació dels serveis oferts.Dos punts seran claus per tal que la discoteca funcioni correctament. Primer de tot, el fet que sigui coneguda per un gran públic, i llavors que aquest públic en qüestió estigui content amb el serveis oferts. És per això que hem destinat un gran nombre de recursos en màrqueting (pàgina web, mailing , SMS...) i ens hem centrat també amb tots els serveis que podem oferir (guarda-roba, sales VIP...). La reputació, ens han dit molts responsables, pot ser l’eina que pot fer del teu projecte una gran font d’ingressos, o el contrari, una gran pèrdua de diners.També ens hem centrat en el personal i el subministrament de begudes, calculant així quin és el nombre de treballadors necessaris per tirar endavant el projecte, i quin és l’estoc de begudes òptim que hem de tenir per cobrir tota la demanda.Finalment, hem tingut en compte els impostos que hem d'incórrer a un projecte d'aquest tipus, ja sigui impost de societats, el cost de la llicència per exercir l'activitat, IVA, etc.Una conclusió és clara després de la realització d’aquest projecte: la nostra discoteca és rendible, i per extensió qualsevol altre amb un nombre considerable d’assistència. El valor afegit que crea un projecte d’aquestes magnituds és tan gran, i la despesa mitjana de la gent en oci nocturn tan considerable, que un projecte capaç de portar un nombre de clients relativament petit en funció del local, pot presentar beneficis

Sexualidade na educação pré-escolar

O presente trabalho retrata á sexualidade na educação pré-escolar, mostra que a sexualidade, é um tema relevante como qualquer outro, merecendo a mesma atenção, devendo ser trabalhada de forma clara e verdadeira de tal maneira, que as crianças sintam que podem tirar suas dúvidas sem sentirem falta de interesse, quer por parte dos adultos quer por parte dos educadores, quer ainda por falta de firmeza dos mesmos. A base teórica da pesquisa buscou nos textos disponíveis o histórico, a legislação e as aplicações da sexualidade na educação infantil ou pré-escolar. O estudo foi suportado pela amostra aleatória simples e contou com quinze participantes afecto as monitoras dos jardins infantis e sessenta pais desses mesmos educandos. O instrumento utilizado para colecta de dados foi aplicação de questionários para as aludidas monitoras e os mencionados pais. Para esta pesquisa seleccionamos quatro jardins infantis da zona da Fazenda, arrabalde desta Capital, designadamente, no Jardim Piquinoti; Jardim Tia Dulce; Jardim Sorriso; Jardim Escolinha Encanto, tendo concluído com os pais das crianças afectas aos referidos Jardins. O estudo demostrou que a importância da sexualidade na educação pré-escolar é comprovada pela literatura consultada, sendo posteriormente, bastas vezes corroborado com os resultados obtidos.

When to carry eccentric products? Optimal retail assortment under consumer returns

To understand whether retailers should consider consumer returns when merchandising, we study howthe optimal assortment of a price-taking retailer is influenced by its return policy. The retailer selects itsassortment from an exogenous set of horizontally differentiated products. Consumers make purchase andkeep/return decisions in nested multinomial logit fashion. Our main finding is that the optimal assortmenthas a counterintuitive structure for relatively strict return policies: It is optimal to offer a mix of the mostpopular and most eccentric products when the refund amount is sufficiently low, which can be viewed asa form of risk sharing between the retailer and consumers. In contrast, if the refund is sufficiently high, orwhen returns are disallowed, optimal assortment is composed of only the most popular products (a commonfinding in the literature). We provide preliminary empirical evidence for one of the key drivers of our results:more eccentric products have higher probability of return conditional on purchase. In light of our analyticalfindings and managerial insights, we conclude that retailers should take their return policies into accountwhen merchandising.

Insects of forensic importance from Rio Grande do Sul state in southern Brazil

The experiment was conducted throughout the year 2005, at the Universidade Federal de Pelotas campus. The objectives of the study were to analyze the decomposition of rabbit (Oryctolagus cunniculus L.) with mean weight 2.67 Kg carcass and describe the interaction of insects acting on it, as well as the insect's potential use in legal medicine. We collected 5.239 insect specimens; 1.827 of them were obtained from larvae collected from carcasses and reared. The specimens were identified and 20 species were of forensic importance. The species Lucilia eximia (Wiedemann, 1819) and Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae) were better indicators of post-mortem interval (PMI) because they occurred in all seasons and were the first to reach the carcass. Hemilucilia semidiaphana (Rondani, 1850), H. segmentaria (Fabricius, 1805) (Diptera, Calliphoridae), Muscina stabulans (Fallén, 1817) and Synthesiomyia nudiseta (Wulp, 1883) (Diptera, Muscidae) can disclose death time because they occur only in certain months of the year. Oxyletrum discicolle (Brullé, 1840) (Coleoptera, Silphidae) and Dermestes maculates De Geer, 1774 (Coleoptera, Desmestidae) were found in advanced stages of decomposition.

On the performance of small-area estimators: Fixed vs. random area parameters

Most methods for small-area estimation are based on composite estimators derived from design- or model-based methods. A composite estimator is a linear combination of a direct and an indirect estimator with weights that usually depend on unknown parameters which need to be estimated. Although model-based small-area estimators are usually based on random-effects models, the assumption of fixed effects is at face value more appropriate.Model-based estimators are justified by the assumption of random (interchangeable) area effects; in practice, however, areas are not interchangeable. In the present paper we empirically assess the quality of several small-area estimators in the setting in which the area effects are treated as fixed. We consider two settings: one that draws samples from a theoretical population, and another that draws samples from an empirical population of a labor force register maintained by the National Institute of Social Security (NISS) of Catalonia. We distinguish two types of composite estimators: a) those that use weights that involve area specific estimates of bias and variance; and, b) those that use weights that involve a common variance and a common squared bias estimate for all the areas. We assess their precision and discuss alternatives to optimizing composite estimation in applications.

Sobrevivência de pupas de Lucilia eximia (Wiedemann) (Diptera, Calliphoridae) após submersão em laboratório

Entre Maio e Junho de 2008 foi observado a sobrevivência das pupas de Lucilia eximia (Diptera, Calliphoridae) após submersão em laboratório. Para este experimento foram utilizadas 480 pupas de mesma idade, sendo estas divididas em oito grupos: o controle não foi submerso e os demais grupos foram submersos de um a sete dias. O aumento do período de submersão diminui a sobrevivência, com um dia de submersão a sobrevivência é de 80%, com dois dias 40%, é de 30% a partir do terceiro dia, no quarto dia cai para 23,34% e no quinto dia fica em 10%. Após este período a mortalidade sobe para 100%. Este padrão pode ser explicado pela curva "U-shaped" que ocorre no consumo de O2 durante o período pupal, onde o consumo é maior no início e no final do período pupal. O tempo de submersão também afeta o tempo de desenvolvimento, aumentando o período pupal. Estes dados têm o potencial para serem utilizados em investigações envolvendo Entomologia Forense, para a estimativa do tempo de submersão de um cadáver.

Rate of development of forensically-important Dipterain southern Brazil

Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 in the southernmost state of Rio Grande do Sul, Brazil. The larvae were fed ground beef at ambient temperatures following collection from carcasses. The development of each species under these conditions was estimated. The most abundant species in the carcasses were Lucilia eximia (Wiedemann) and Chrysomya albiceps (Wiedemann) (Calliphoridae), and they were found in all seasons. The data were fitted to a linear model that describes the relationship between temperature and linear developmental rating. These two species are primary forensic indicators in southern Brazil. Other species such as Hemilucilia semidiaphana (Rondani) (Calliphoridae), Synthesiomyia nudiseta (Wulp), Muscina stabulans (Fallen) (Muscidae), and Fannia pusio (Wiedemann) (Fanniidae) were forensically less important because they only occurred in high frequency in certain seasons and during the first days of carcass decomposition.

Improving small area estimation by combining surveys: new perspectives in regional statistics

A national survey designed for estimating a specific population quantity is sometimes used for estimation of this quantity also for a small area, such as a province. Budget constraints do not allow a greater sample size for the small area, and so other means of improving estimation have to be devised. We investigate such methods and assess them by a Monte Carlo study. We explore how a complementary survey can be exploited in small area estimation. We use the context of the Spanish Labour Force Survey (EPA) and the Barometer in Spain for our study.

Effect of silicon and acibenzolar-s-methyl on colored cotton plants infested or not with Aphis gossypii Glover (Hemiptera, Aphididae)

Effect of silicon and acibenzolar-s-methyl on colored cotton plants infested or not with Aphis gossypii Glover (Hemiptera, Aphididae). The aphid Aphis gossypii is an insect pest that causes damage mainly at the beginning of the cotton plant development. The effect of resistance inductors silicon and acibenzolar-s-methyl (ASM) on the development of colored cotton plants were researched in the presence and absence of A. gossypii. Three colored cotton cultivars were sown in pots and individually infested with 25 apterous aphids, 13 days after the application of the inductors. Fifteen days after plant emergence, the silicon was applied at a dosage equivalent to 3 t/ha and acibenzolar-s-methyl in 0.2% solution of the product BION 500®. After 21 days of infestation the following parameters were evaluated: plant height, stem diameter, dry matter of aerial part and root, and total number of aphids replaced. It was verified that the plant height was reduced in the presence of aphids and all variables were negatively affected by the application of ASM. However, silicon did not affect plant development.

Médicalisation de la société et durabilité des systèmes de santé

La thématique de la médicalisation de la vie et de la société remonte au début du siècle passé lorsque la génialité de Jules Romains fait dire au docteur Knock que "les biens portants ne sont que des malades qui s'ignorent", successivement en 1976, lors d'un interview à la revue économique Fortune, Henry Gadsen, CEO de MSD, déclara que son rêve était de produire des médicaments pour les biens portants (rêve aujourd'hui déjà abondamment réalisé), plus récemment un "incipit" d'un article paru sur le British Medical Journal du 13 avril 2002 nous rappelait qu'on peut faire beaucoup d'argent si l'on arrive a convaincre les bienportants qu'en réalité ils sont des malades. En Suisse, en 1996 déjà, Alex Müller, président de l'Académie Suisse des Sciences Médicales, constatait que "nous souffrons en Suisse d'une surmédicalisation; les contradictions d'une société surmédicalisée rendent nécessaire une redéfinition des objectifs qui passe par la triple révision des pratiques, du développement scientifique et des valeurs de la santé".

Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae) in crop succession at central Brazil

Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae) in crop succession at central Brazil. Beetles of the family Melolonthidae make up a large group and some species are considered pests of planted crops. Little information is available on the basic biological aspects of the genus Leucothyreus, such as association with cultivated crops and their occurrence periods. Therefore studies were developed in soybean and corn crops in Tangará da Serra, Mato Grosso, Brazil, with the objective of studying the occurrence and biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus. For acquisition of immature specimens of both species, in April 2011 sampling was performed in corn fields, in July and October in the fallow area, and in soybeans fields planted in December; in 2012 sampling was performed in January and February in soybean fields and in March in corn fields. In 2011 the total number of larvae obtained in April, July, October and December were 100, 6, 30 and 27, and in January, February and March of 2012 these quantities were 32, 52 and 65 larvae, respectively. In all sampling events the larvae of L. alvarengai were collected in greater quantity. At the beginning of the reproductive period of L. alvarengai and L. aff. semipruinosus, it was observed that the adults began to fly and soon after started oviposition in the field in September. The appearance of larvae coincides with the time of soybean planting in the field, thus the larvae feed on roots of soybean plants at the beginning of their development and the cycle from egg to adult of the two species was completed in one year.
