In order to differentiate from competitors in terms of customer service, warehouses accept late orders while providing delivery in a quick and timely way. This trend leads to a reduced time to pick an order. This paper introduces workload forecasting in a warehouse context, in particular a zone picking warehouse. Improved workforce planning can contribute to an effective and efficient order picking process. Most order picking publications treat demand as known in advance. As warehouses accept late orders, the assumption of a constant given demand is questioned in this paper. The objective of this study is to present time series forecasting models that perform well in a zone picking warehouse. A real-life case study demonstrates the value of applying time series forecasting models to forecast the daily number of order lines. The forecast of order lines, along with order pickers’ productivity, can be used by warehouse supervisors to determine the daily required number of order pickers, as well as the allocation of order pickers across warehouse zones. Time series are applied on an aggregated level, as well as on a disaggregated zone level. Both bottom-up and top-down approaches are evaluated in order to find the best-performing forecasting method.

La présente contribution a pour objectif de proposer un état de lieux de l’incidence du droit de l’Union européenne sur le développement, la promotion et la règlementation de l’économie collaborative au sein du marché intérieur. Pour ce faire, cet article se divise en deux parties. Dans la première partie, le phénomène de l’économie collaborative ainsi que les approches réglementaires envisagées par les institutions de l’Union européenne pour mieux encadrer cette économie seront analysés. Nous soulignerons que l’Union européenne décide pour l’instant de ne pas proposer de nouveaux instruments de réglementation, préférant plutôt interpréter les instruments et dispositions déjà existants du droit de l’Union européenne. S’inscrivant dans cette approche, la deuxième partie de la contribution dressera une cartographie des dispositions pertinentes du droit de l’Union européenne qui gouvernent l’économie collaborative, en proposant des lignes directrices supplémentaires qui devraient permettre d’encore mieux intégrer l’économie collaborative dans le cadre juridique de l’Union européenne.

Access-based services (ABS), which grant customers limited access to goods without any transfer of ownership, are unique technology-based service innovations requiring the substantial involvement and collaboration of customers, without employees’ supervision. Although ABS offer several potential advantages, convincing customers to use them remains challenging. Combining 56 in-depth interviews with supplementary literature, the authors address this challenge by proposing an integrative framework that reflects the (1) barriers that prevent customers from using ABS and (2) practices in which customers engage to attenuate those barriers. The complex, multidimensional barriers relate not only to the service and technology features but also to other customers. Customers can engage in different practices to attenuate perceived barriers and create value, namely, “to distance,” “to manage,” “to elaborate,” “to control,” and “to relate.” Yet they regard these barrier-attenuating practices as necessary sacrifices to use ABS. Complementing suggestions that customers adopt and use ABS to escape the burdens of ownership, the current research reveals that customers actually may confront several “burdens of access.” This research suggests managers who wish to reduce rejection of their innovation could not only overcome customers’ perceived barriers, but also facilitate and reduce the number of practices in which customers engage to attenuate those barriers themselves.

Orange Flowers and Incense to the Glory of the King in the French Festivals of 1622 The communication explores the way in which the festival apparatus establishes a sacred dimension in the ordinary space and time of the city. We consider the immaterial devices of the spectacular apparatus: light, sound, with special attention to the smell, its iconic power and liturgical significance. The study is conducted on the iconographic and textual descriptions of two kind of celebrations which took place during the summer and autumn of 1622 in France: Louis’s triumphal entries following his victories against the Protestant rebels, and the solemnities for canonization of Jesuits Ignatius of Loyola and Francis Xavier, miles of catholic faith between Europe and Asia. In this historical perspective where sacred/secular points converge, these festivals contribute to shape the imago gloriae on the urban space through the ephemeral language of festival and its indelible poli-sensory effect on audience’s memory.

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [less ▲]

Dans le dernier quart du XVIe siècle, Philippe II d’Espagne est à la tête de l’ensemble territorial le plus puissant d’Europe. Fils préféré de l’Église romaine et souverain reconnu d’une grande partie de l’Italie, il exerce une influence considérable sur la papauté à travers l’action de son ambassadeur espagnol résidant près le Saint-Siège. Ce dernier a pour tâche d’étendre le réseau des alliés au sein de la Curie. Il chapeaute aussi les différents services diplomatiques et ecclésiastiques des États de la monarchie présents dans la cité des papes . Si elle conserve une certaine autonomie, la légation des Pays-Bas et de la Franche-Comté près le Saint-Siège – conduite par l’agent Laurent du Blioul de 1573 à 1598 – est également soumise à la volonté de cet envoyé. Ce n’est d’ailleurs pas un hasard si l’étude de la légation à l’époque du règne de Philippe II a peu passionné les historiens . Effacée derrière la puissance de l’ambassadeur espagnol, celle-ci semble être un piètre avatar des services ecclésiastiques et diplomatiques dépêchés à Rome par les ducs de Bourgogne , Philippe le Beau ou les archiducs Albert et Isabelle . Or, si, aux temps de Laurent du Blioul, la légation, considérée en tant qu’actrice isolée dans le paysage romain, joue un rôle modeste qui se cantonne au suivi des affaires ecclésiastiques provenant des Pays-Bas et de la Franche-Comté, il faut envisager qu’elle fait partie intégrante d’une toile religieuse, diplomatique, sociale et politique plus vaste tissée à Rome par le roi Philippe II et ses agents. Dépassant les seuls intérêts des Pays-Bas, l’étude de cette institution conduit à appréhender tout un pan de la stratégie politique habsbourgeoise. L’imbrication de la légation dans le théâtre diplomatique espagnol à Rome a deux facettes : si, d’une part, elle limite les prérogatives institutionnelles de l’agent du Blioul, d’autre part, elle favorise régulièrement l’efficacité de son action.

This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No pier effect or air venting is considered in the study. The velocity field is measured by Bubbles Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparison of measured velocities between both spillways indicates low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity calculated from the relative pressure considering a potential flow finally emphasizes that bottom pressure amplitudes seem overestimated for the larger spillway, while an averaging effect might operate for the pressure measurements on the smaller spillway.

Jhumpa Lahiri’s work is unusual for the ways in which it challenges the interlocked ‘matrophobic’ and assimilationist streaks at play in US ethnic and South Asian American literature. Taking its cue from Marianne Hirsch, this chapter examines how Lahiri’s ‘mother-friendly’ versions of the mother-daughter relationship have the potential to complicate the predetermined scripts pertaining to representations of the Indian-American diaspora as a ‘model diaspora’ by the homeland and a ‘model minority’ by the US, while opening new gendered vistas on silenced histories.

Estrogens derived from brain testosterone aromatization (neuro-estrogens) are critical for the activation of male sexual behavior. Their effects on this behavior are typically associated with long-term changes in circulating levels of testosterone and the transcriptional activity of their liganded nuclear receptors. According to this view, neuro-estrogens would prime the neural circuits controlling the long-term expression of behavior, which would then be acutely regulated by neurotransmitter systems conveying information from the social environment. In parallel, neuro-estrogens are also able to produce much faster effects than previously anticipated. Our recent investigations in Japanese quail revealed an interesting dichotomy in the regulation of male sexual behavior by membrane- and nuclear-initiated estrogen signaling providing respectively an acute modulation of sexual motivation and a long-term control of the capacity to display the copulatory sequence. In parallel, a similar dichotomy applies to the regulation of brain aromatase whose expression depends on the transcriptional activity of testosterone metabolites while its enzymatic activity is rapidly regulated in a region- and context-dependent manner. Recent evidences suggest that rapid changes in sexual motivation result from rapid changes in local estrogen production. Together, these data support the idea that the acute regulation of some aspects of male sexual behavior depends not only on classical neurotransmitter systems, but also on rapid and spatially restricted changes in local estrogen availability. The existing literature suggests that this acute regulation by neuro-estrogens of the motivational aspects of behavior could be generalized to other systems such as singing behavior in songbirds.
