Use of emerging technologies to assess differences in outdoor physical activity in St. Louis, Missouri.

Introduction: Abundant evidence shows that regular physical activity (PA) is an effective strategy for preventing obesity in people of diverse socioeconomic status (SES) and racial groups. The proportion of PA performed in parks and how this differs by proximate neighborhood SES has not been thoroughly investigated. The present project analyzes online public web data feeds to assess differences in outdoor PA by neighborhood SES in St. Louis, MO, USA.
Methods: First, running and walking routes submitted by users of the website MapMyRun.com were downloaded. The website enables participants to plan, map, record, and share their exercise routes and outdoor activities like runs, walks, and hikes in an online database. Next, the routes were visually illustrated using geographic information systems. Thereafter, using park data and 2010 Missouri census poverty data, the odds of running and walking routes traversing a low-SES neighborhood, and traversing a park in a low-SES neighborhood were examined in comparison to the odds of routes traversing higher-SES neighborhoods and higher-SES parks.
Results: Results show that a majority of running and walking routes occur in or at least traverse through a park. However, this finding does not hold when comparing low-SES neighborhoods to higher-SES neighborhoods in St. Louis. The odds of running in a park in a low-SES neighborhood were 54% lower than running in a park in a higher-SES neighborhood (OR = 0.46, CI = 0.17-1.23). The odds of walking in a park in a low-SES neighborhood were 17% lower than walking in a park in a higher-SES neighborhood (OR = 0.83, CI = 0.26-2.61).
Conclusion: The novel methods of this study include the use of inexpensive, unobtrusive, and publicly available web data feeds to examine PA in parks and differences by neighborhood SES. Emerging technologies like MapMyRun.com present significant advantages to enhance tracking of user-defined PA across large geographic and temporal settings.

Guerre et exil chez Louis-Ferdinand Céline

O nosso estudo incide, primordialmente, sobre as polémicas de carácter político e consequentes acusações de que Louis-Ferdinand Céline foi – e continua a ser – alvo. Tais aspectos conduzem-nos a questionar, com alguma veemência e perplexidade, as razões da sua fuga através da Alemanha, bem como as relações que estabeleceu com os Nazis durante a segunda guerra mundial. Num primeiro momento, elaborámos uma contextualização de cariz temporal e factual, tentando perceber – quiçá explicar -, o sentido das posições assumidas por Céline aquando da composição dos seus pamphlets, marcada por uma reivindicação violenta do seu antisemitismo e que surge, omnipresente, sob forma de cartas, entrevistas e outros escritos. Contudo, a essência do nosso trabalho consistiu numa análise detalhada das diferentes etapas dos anos de exílio do escritor, primeiro numa Alemanha devastada pela guerra, onde se refugia a partir de 17 de Junho de 1944 e mais tarde, na Dinamarca (1945-1951), de onde terá de responder às acusações de traição que lhe são dirigidas pela justiça francesa, antes de um regresso sem glória, a França, e de uma reabilitação tardia e titubeante. Os escritos que constituem o corpus do nosso trabalho traduzem, de modo inequívoco, a experiência amarga e cruel dos anos de exílio e da lembrança feita de dor e ódio, que o escritor sentiu profundamente, como um espinho na própria carne. Apesar do caminho tortuoso, que lhe confere uma aura de escritor “maldito”, Céline permanece, ainda hoje, como um dos maiores génios da literatura francesa do século XX.

Pollen Allergy in Cordoba City: Frequency of Sensitization and Relation with Antihistamine Sales

The occurrence of symptoms in pollen allergy patients in urban areas may be affected by local environmental factors such as sources of pollution, natural and ornamental vegetation, local architecture impeding dispersion, etc. The aim of this study was to analyse the frequency of sensitization in pollen allergy patients and the relationship with antihistamine sales. For this study, a large number of clinical records, together with pharmaceutical and pollen data, were collected between 1999 and 2001 in the city of Córdoba, in the south of the Iberian Peninsula. Differences were observed in the symptoms suffered by pollen allergy patients in different areas of the city due to varying local emission of both biological and non-biological particles. Temporal distribution of symptoms over the three study years was influenced by meteorological factors, especially rainfall patterns; higher water supply to plants was associated with increased airborne pollen concentrations. Air pollution might be one of the main factors affecting the distribution of pollen allergy patients within the city. Recent years have seen a worsening of symptoms and increased sensitization to urban species such as plane-trees.

Managing sales people strategically when promoting new products: Incorporating market orientation into a sales management control framework

Salespeople play a pivotal role in promoting new products. Therefore, managers need to know what control mechanism (i.e., output-based control, behavior-based control, or knowledge-based control) can improve their salespeople's new product sales performance. Furthermore, managers may be able to assist salespeople in performing better by having a strong market orientation. The literature has been inconsistent regarding the effects of sales management control mechanisms and has not yet incorporated market orientation into a sales management control framework. The current study surveyed 315 Taiwanese salespeople from publicly traded electronics companies with the aim of contributing to the sales management literature. The results show that sales management controls can directly affect salespeople's innovativeness, which, in turn, affects new product sales performance. However, sales management controls cannot affect performance directly. Furthermore, market orientation can positively moderate the relationship between salespeople's innovativeness and new product sales performance.

Performance of state space and ARIMA models for consumer retail sales forecasting

Forecasting future sales is one of the most important issues that is beyond all strategic and planning decisions in effective operations of retail businesses. For profitable retail businesses, accurate demand forecasting is crucial in organizing and planning production, purchasing, transportation and labor force. Retail sales series belong to a special type of time series that typically contain trend and seasonal patterns, presenting challenges in developing effective forecasting models. This work compares the forecasting performance of state space models and ARIMA models. The forecasting performance is demonstrated through a case study of retail sales of five different categories of women footwear: Boots, Booties, Flats, Sandals and Shoes. On both methodologies the model with the minimum value of Akaike's Information Criteria for the in-sample period was selected from all admissible models for further evaluation in the out-of-sample. Both one-step and multiple-step forecasts were produced. The results show that when an automatic algorithm the overall out-of-sample forecasting performance of state space and ARIMA models evaluated via RMSE, MAE and MAPE is quite similar on both one-step and multi-step forecasts. We also conclude that state space and ARIMA produce coverage probabilities that are close to the nominal rates for both one-step and multi-step forecasts.

How to promote and enhance communication between a big retailer's after-sales department and its suppliers

W is the biggest electronic goods retailer in Portugal accounting with almost fifty percent of market share in its area. During the last years, many small W suppliers had to close their doors, and many others are in huge troubles. Among the reason for this situation, the huge bargaining power of W in the relationship seems crucial. The focus of the directed research will be in the after sales department where I did an internship from September 2014 to January 2015.
