Using Daily Store-level Data to Understand Price Promotion Effects in a Semiparametric Regression Model
2009
Though it has been widely reported in the marketing literature that temporary price discounts generate substantial short-term sales increase, the shape of the deal effect curve constitutes a key research topic, for which there are still limited empirical results. To address this issue, a semiparametric regression approach is used to model the complex nature of this phenomenon. Our model is developed at the brand level using daily store-level scanner-data, which allows the study of several nonreported promotional effects, such as the influence of the day of the week both in promotional and nonpromotional periods. The results show that the weekend is the most effective in increasing promotion…
Accounting for previous events to model and predict traffic accidents at the road segment level: A study in Valencia (Spain)
2022
Abstract Predicting the occurrence of traffic accidents is essential for establishing preventive measures and reducing the impact of traffic accidents. In particular, it is fundamental to make predictions using fine spatio-temporal units. In this paper, the daily risk of traffic accident occurrence across the road network of Valencia (Spain) is modeled through logistic regression models. The spatio-temporal dependence between the observations is accounted for through the inclusion of lagged binary covariates representing the previous occurrence of a traffic accident within a spatio-temporal window centered at each combination of day and segment of the network. A temporal distance of 28 days…
Daily steps among Finnish adults: Variation by age, sex, and socioeconomic position
2011
Aims: The aim of this study was to provide descriptive population-based pedometer data from adults aged 30-45 years in Finland, and to compare daily step counts with evidence-based indices. Methods: The data was collected from 1853 participants in 7 consecutive days in winter 2007—08 in part of 27-year follow up of the Cardiovascular Risk in Young Finns study. Results: The participants took (mean±standard deviation) 7499 ± 2908 steps/day. Step counts included 1925 ± 2052 aerobic steps/day gathered in bouts of at least 10 min continuous ambulatory activity. Women had more total steps than men ((7824 ± 2925 vs. 7089 ± 2774; p < 0.001). Although participants had higher mean total steps on …
Gender and age distribution of motorcycle crashes in Spain.
2018
This study analysed motorcycle crashes in Spain. Ninety-nine thousand three hundred and four motorcycle crash reports filed in the years 2006-2011 were extracted from the Directorate General of Traffic database of crashes with victims. These data were analysed in terms of gender, age groups, trip purpose, type of crash, speed violation, day of the week, harm caused, use of helmet and psychophysical conditions of the driver to study the characteristics of motorcycle crashes in Spain and to assess the differences between male and female motorcycle drivers in these crashes. Significant differences were found in all the variables considered in the study, which implies gender differences in the …
Seasonal and daily variation in physical activity among three-year-old Finnish preschool children
2013
The purposes of this study were to assess seasonal, daily, and gender variations in children’s physical activity (PA). ActiGraph GT3X accelerometers were used to record the three-year-old children’s PA levels for five consecutive days in autumn and winter. Complete data for both seasons were obtained for 47 children. Despite a significant difference in seasonal temperatures (p < .001), differences were only found for weekdays light PA (p = .021). No difference in PA was observed between weekdays and weekend days. Only 20% of the sample had ≥120 minutes light-to-vigorous PA (LMVPA), and 46% of children had ≥60 minutes moderate-to-vigorous PA (MVPA). Boys spent more minutes in LMVPA (p = .001…
Relationships between time of day, day of the week, and positive mood: Exploring the role of the mood measure
1995
This study examined the relationship between time of day, day of the week, and two measures of positive affect (PA). According to previous research and the circumplex model of affect, one scale was designed to assess the activation component of PA, and the other one measured the pleasantness aspect. Subjects rated their mood three times a day for 7 consecutive days. Consistent with our hypotheses, PA-Pleasantness showed a peak on the weekend, whereas PA-Activation remained stable throughout the week. Regarding time of day, maximum PA-Activation was reached in the afternoon. In contrast, the Pleasantness component of PA increased from morning to evening. Implications of these results as well…
Variability of Spanish adolescents’ physical activity patterns by seasonality, day of the week and demographic factors
2008
Abstract In this study, we examined the variability of physical activity (and inactivity) patterns in relation to gender, age, type of school, day of the week, and season of the year among a sample of Spanish adolescents aged 12–16 years. Levels of physical activity engagement, “who” was active/inactive, and “when” they were active/inactive were addressed. A Spanish translation and modification of Cale's Four by One-Day Physical Activity Questionnaire was administered by interviewer to 323 participants to measure estimated energy expenditure. Activity was assessed for two weekdays and two weekend days on two occasions during the autumn and two occasions during the winter. In an effort to be…
Investor Inattention to All-Cash Acquisition Announcements: A Joint Day-Time Analysis in the Spanish Market
2021
Prior studies suggest that investors have limited attention, which determines the speed with which information is incorporated into share prices and, in turn, affects the efficiency of the markets. Unlike other corporate events, the information contained in an acquisition announcement is generally less standard and more complicated to process. Therefore, investor inattention is less likely around this event. In this study we test the existence of investor inattention for a sample of all-cash acquisition announcements of listed and unlisted target firms released by listed Spanish firms from 1998 to 2018. Cash acquisitions allow us to control for the strategic behavior of overvalued companies…
