Early Word Comprehension in Infants: Replication and Extension.

A handful of recent experimental reports have shown that infants of 6 to 9 months know the meanings of some common words. Here, we replicate and extend these findings. With a new set of items, we show that when young infants (age 6-16 months, n=49) are presented with side-by-side video clips depicting various common early words, and one clip is named in a sentence, they look at the named video at above-chance rates. We demonstrate anew that infants understand common words by 6-9 months, and that performance increases substantially around 14 months. The results imply that 6-9 month olds' failure to understand words not referring to objects (verbs, adjectives, performatives) in a similar prior study is not attributable to the use of dynamic video depictions. Thus, 6-9 month olds' experience of spoken language includes some understanding of common words for concrete objects, but relatively impoverished comprehension of other words.

Black-White Wage Gap Among Restaurant Servers: A Replication, Extension, and Exploration of Consumer Racial Discrimination in Tipping

There is a rich history of social science research centering on racial inequalities that continue to be observed across various markets (e.g., labor, housing, and credit markets) and social milieus. Existing research on racial discrimination in consumer markets, however, is relatively scarce and that which has been done has disproportionately focused on consumers as the victims of race-based mistreatment. As such, we know relatively little about how consumers contribute to inequalities in their roles as perpetrators of racial discrimination. In response, in this paper we elaborate on a line of research that is only in its’ infancy stages of development and yet is ripe with opportunities to advance the literature on consumer racial discrimination and racial earnings inequities among tip dependent employees in the United States. Specifically, we analyze data derived from a large exit survey of restaurant consumers (n=378) in an attempt to replicate, extend, and further explore the recently documented effect of service providers’ race on restaurant consumers’ tipping decisions. Our results indicate that both White and Black restaurant customers discriminate against Black servers by tipping them less than their White coworkers. Importantly, we find no evidence that this Black tip penalty is the result of interracial differences in service skills possessed by Black and White servers. We conclude by delineating directions for future research in this neglected but salient area study.

Efficacité différentielle de la publicité internationale : extension, adaptation ou invention

[…] Les objectifs de cette étude sont doubles: d’une part, l'auteur s’efforcera de développer un cadre théorique permettant de replacer le problème de la transférabilité du message dans son contexte, c'est-à-dire un processus de communication inter-culturel. D’autre part, l'auteur tentera de comparer expérimentalement l'efficacité d'un message transféré d'un environnement culturel donné (A) vers un autre environnement culturel (B), et celle d'un message adapté à l'environnement culturel (B). Le problème de la sélection des media, qui fait partie intégrante de la définition d'une campagne publicitaire sera volontairement laissé de côté. […]

On the extension complexity of combinatorial polytopes

In this paper we extend recent results of Fiorini et al. on the extension complexity of the cut polytope and related polyhedra. We first describe a lifting argument to show exponential extension complexity for a number of NP-complete problems including subset-sum and three dimensional matching. We then obtain a relationship between the extension complexity of the cut polytope of a graph and that of its graph minors. Using this we are able to show exponential extension complexity for the cut polytope of a large number of graphs, including those used in quantum information and suspensions of cubic planar graphs.

Delivering Regional Extension in Qld Farming Systems - Central Queensland

The CQ Cotton Regional Extension project has been a key to the delivery of emerging, cutting edge research information and knowledge to the Central Queensland cotton industry. The direct relevance of southern research to cotton production under the conditions experienced in CQ always has been an issue which could be addressed through regional assessment and adaptation. The project links the national research to the region through development and extension, with a strong focus on the major industry production issues including but not limited to disease, Integrated Pest Management (IPM), soils, nutrition and integrated weed management. Susan Mass has supported the implementation of national industry-wide programs particularly the industry Best Management Practices program (myBMP). This project has successfully transitioned to a focus on delivering national outcomes in target lead areas as part of National Development and Delivery Team established by Cotton CRC, CRDC and Cotton Australia, while maintaining a regional extension presence for Central Queensland cotton & grain farming systems. Susan Mass has very effectively merged and integrated strong regional extension support to cotton growers in Central Queensland with delivery of industry extension priorities across the entire industry in the Development and Delivery Team model. Susan is the target lead for disease and farm hygiene. Recognising the challenges of having regionally relevant research in Central Queensland, this project has facilitated locally based research including boll rot, Bt cotton resistance management, and mealybug biology through strong collaborations. This collaborative approach has included linkage to Department of Environment and Resource Managmeent (DERM) groups and myBMP programs resulting in a high uptake in CQ.

Fish handling, processing and storage in Uganda: the role of the extension worker

The handling and processing of fish in Uganda has until recently been carried out exclusively by the artisanal fishermen and fish processors. Their operations have left much to be desired as the product is often of low quality 'and its keeping time is limited. The handling of fresh fish has been without refrigeration but with the recent establishment of commercial fish processing plants a cold chain of fish distribution is being set up for domestic and export markets. Some of the fishermen are beginning to ice their catch immediately after reaching the shore. It is hoped that fishmongers will increasingly find it more profitable to market their products iced. This will make fish available to a large sector of the population and in the process there will be reduced post-harvest losses.

Concertation communautaire pour l'aménagement et le développement du quartier Parc Extension à Montréal

Ce document présente le processus de mise en oeuvre du plan d'aménagement du quartier Parc Extension à Montréal auquel j'ai activement participé. Initiée et planifiée en 2000, la démarche sera couronnée en 2003. L'objectif de cette initiative est de procurer aux intervenants publics, communautaires et privés un outil servant de cadre de référence afin de mieux cerner les priorités et enjeux locaux. Nous croyons qu'un tel outil suscitera l'avènement de partenariats intéressants à court, moyen et long termes, au bénéfice des résidents et résidentes du quartier. Dans un premier temps nous soulignons les caractéristiques spécifiques de Parc Extension afin de mieux saisir l'état de la situation locale. Cette compréhension devrait ensuite être facilitée par la présentation du profil des acteurs du milieu. Ces deux sections permettent au lecteur de se familiariser avec la dynamique présente. Dans un deuxième temps, nous présentons la démarche globale de l'élaboration du plan d'aménagement. Nous verrons tout d'abord l'historique et la description du processus, puis quels sont les objectifs poursuivis. Enfin nous pourrons lire le résumé-synthèse du plan, qui demeure temporaire puisqu'il s'agit d'un document de travail à ce jour. Dans la section suivante, nous approfondissons la démonstration des retombées d'un tel plan en prenant le cas de l'habitation. En effet, nous y verrons quel est le portrait de la situation, quelles instances s'activent en la matière, ce qui se fait présentement et ce qui est proposé pour l'avenir. Le thème de l'habitation illustre concrètement la pertinence d'une concertation dans l'identification des priorités. L'expression de cette concertation se traduit par des consensus menant à des actions et projets sur le terrain. Des résultats intéressants sont obtenus. Nous poursuivons alors avec les aspects théoriques. A cette étape, nous abordons la question de l'évaluation ultérieure dans le futur par la proposition d'indicateurs. Ceux-ci permettraient de mieux cerner les résultats et impacts dans quelques armées. Nous analysons également le potentiel de transférabilité de l'expérience envers d'autres milieux. Finalement, sur une note plus personnelle, je décris mes savoirs faire et savoirs être développés au cours de ce projet. Je tente une auto-analyse de mes points forts et à améliorer. Un résumé critique de l'ensemble de l'expérience vient compléter l'essai. En conclusion, nous rappelons les avantages du plan d'aménagement et un bilan des avancées franchies à ce jour.
