Ordinal Probit

Affective product design, which concentrates on customers’ affective responses and aspirations, is arousing increasing attention. In this paper, ordinal probit regression (OPR) is introduced into this field to discover mapping knowledge from design elements to customer affect, and a comparative study is always recommended between OPR and ordinal logistic regression (OLR) for available data to choose a better fitted model. The discovered mapping relations could facilitate the handling of affective information and assist the designer to make trade-off decisions. A case study of cell phone design was conducted. Four generic affective dimensions and six key product attributes of the cell phone were identified. OPR and OLR were applied successively to reveal the quantitative relations from design elements to customer affect. For the two models, five classes of indexes were compared. The findings show that OLR is superior to OPR to fit the collected data.

Data Collection Procedure

The concentration of warehouses in peripheral regions of metropolitan areas in a time period is called logistics sprawl (LS). Identifying this phenomenon could help to reduce externalities related to urban freight transport, mainly, the distance traveled. This paper examines the contribution of the characteristics of metropolitan areas on the logistics sprawl indicator. A case study was carried out considering data from eight metropolitan areas of the state of Paraná (Brazil). The research method is based on the data collection procedure proposed, centrographic method, and linear regression. The results of the centrographic method reveal a positive LS in four metropolitan areas and a negative LS in three metropolitan areas. In general, the warehouses are close to the highways that cross the metropolitan area. In addition, the size of the metropolitan area has a negative relationship with the number of warehouses and the logistics sprawl indicator. The findings highlight the importance of public policies relating to urban freight transport and land use at a metropolitan level.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
