The objective of this study is to extend the possibilities of robot localization in a known environment by using the pre-deployed infrastructure of a smart building. The proposed method demonstrates a concept of a Shared Sensory System for the automated guided vehicles (AGVs), when already existing camera hardware of a building can be utilized for position detection of marked devices. This approach extends surveillance cameras capabilities creating a general sensory system for localization of active (automated) or passive devices in a smart building. The application is presented using both simulations and experiments for a common corridor of a building. The advantages and disadvantages are stated. We analyze the impact of the captured frame’s resolution on the processing speed while also using multiple cameras to improve the accuracy of localization. The proposed methodology in which we use the surveillance cameras in a stand-alone way or in a support role for the AGVs to be localized in the environment has a huge potential utilization in the future smart buildings and cities. The available infrastructure is used to provide additional features for the building control unit, such as awareness of the position of the robots without the need to obtain this data directly from the robots, which would lower the cost of the robots themselves. On the other hand, the information about the location of a robot may be transferred bidirectionally between robots and the building control system to improve the overall safety and reliability of the system.

This article considers the impact of preferential, base-specific taxation on equilibrium revenues. While policy makers have argued that it generates a prisoner’s dilemma result, there is mixed support in the academic literature. Using a more plausible model with asymmetric base elasticities and heterogeneity of both firms and countries, I find that preferential taxation can generate greater revenues if countries exhibit sufficient productivity and/or population asymmetry. It is also less distortionary except in cases where moving costs are fully deductible. Allowing for noncorrelated, cross-country profits is the key factor as it generates base expansion effects.

We investigate the impact of being politically connected on bank performance and cost of funding. We study 89 Indonesian banks over the 2001-2008 period disentangled into politically connected banks which can be state-owned banks and private banks as well as non-politically connected banks. Controlling for bank fundamental factors and time effect, we do find that political connections improve bank performance. Moreover, our results provide evidence that politically connected banks are benefited by getting a lower cost of funding. Finally, our result reveals that political connections are less valuable for foreign banks. Keywords: Political Connections; Performance; Cost of Funding; Foreign Banks; Indonesia.

The study aims to explain the determinants of banks’ choices of location of overseas activities and of market-entry mode (subsidiary, branch and representative office). Location of overseas activities and market-entry mode are considered as simultaneously determined. The determinants are based on the factors associated with the characteristics of the parent bank and host country. A 3SLS model is used to estimate these determinants. Based on sample of 63 banks from 18 countries in 2004, the results show that foreign location and market-entry mode are governed by the characteristics of both the host country and the parent bank. Our results also provide some answers about the impact of entry mode on location choice, and vice versa.

ABSTRACTIntroduction:The aim of the present study was to investigate the impact of the duration of untreated illness (DUI)—defined as the time elapsing between the onset of generalized anxiety disorder (GAD) and the first adequate pharmacologic treatment—on treatment response and clinical course in a sample of subjects with GAD.Methods:One hundred patients with GAD, diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision criteria, were enrolled and their main demographic and clinical features collected. Patients were then treated with selective serotonin reuptake inhibitors or venlafaxine for 8 weeks in open-label conditions. Treatment response and other clinical variables were analyzed after dividing the sample into two groups according to DUI (DUI ≤12 months and DUI >12 months).Results:When the DUI was computed with respect to the first antidepressant treatment (DUI-AD), a higher improvement (Clinical Global Impressions-Severity of Illness scale) after the pharmacologic treatment was found in the group with a shorter DUI (analysis of variance with repeated measures: time effect F=654.975, P<.001; group effect: F=4.369, P=.O39). When computed with respect to the first treatment with benzodiazepines (DUI-BDZ), the two groups did not show any significant difference in treatment response (time effect: F=652.183, P<.001; group effect: F=0.009, P=.924). In addition, patients with a longer DUI (DUI-BDZ or DUI-AD) showed an earlier age at onset, a longer duration of illness and a higher rate of comorbid psychiatric disorders with onset later than GAD.Conclusion:Results from this preliminary study seem to suggest that a shorter DUI-AD may determine a better response to pharmacologic treatment in patients with GAD, and that a longer DUI (DUI-BDZ and DUI-AD) may be associated to a worse clinical course. Further investigation on the relationship between DUI and GAD is needed.

We investigated the impact of abdominal obesity status on the cardiovascular response to a fully controlled 4-week isoenergetic Mediterranean diet (MedDiet). Thirty-eight abdominally obese individuals (waist circumference >102 cm in men and >88 cm in women) and thirty-one nonabdominally obese individuals were recruited and studied before and after the MedDiet. All analyses were adjusted for the slight decrease in body weight, which occurred during the MedDiet (mean:0.9±1.2 kg). A group by time interaction was noted for waist circumference (P=0.02), abdominally obese subjects showing a significant decrease and nonabdominally obese subjects a nonsignificant increase (resp., −1.1 and +0.3%). The MedDiet resulted in decreases in total cholesterol, LDL-C, HDL-C, apolipoprotein B, A-1, and A-2, total cholesterol/HDL-C ratio, LDL-C/HDL-C ratio, and systolic and diastolic blood pressure (time effect:P<0.05). For all variables related to glucose/insulin homeostasis, no change was observed except for a decrease in 2 h glucose concentrations (time effect:P=0.03). No group by time interaction was observed in any of the metabolic variables studied. Results from our study suggest that the adoption of the MedDiet leads to beneficial metabolic effects, irrespective of the abdominal obesity status.
