photometric mapping with isophot using the p32 astronomical observation template
Astronomy and Astrophysics, 2003Co-Authors: R Tuffs, Carlos GabrielAbstract:The "P32" Astronomical Observation Template (AOT) provided a means to map large areas of sky (up to 45 45 arcmin) in the far-infrared (FIR) at high redundancy and with sampling close to the Nyquist limit using the ISOPHOT C100 (3 3) and C200 (2 2) detector arrays on board the Infrared Space Observatory (ISO). However, the transient Response Behaviour of the Ga:Ge detectors, if uncorrected, can lead to severe systematic photometric errors and distortions of source morphology on maps. We describe the basic concepts of an algorithm which can successfully correct for transient Response artifacts in P32 observations. Examples are given to demonstrate the photometric and imaging performance of ISOPHOT P32 observations of point and extended sources corrected using the algorithm. For extended sources we give the integrated flux densities of the nearby galaxies NGC 6946, M 51 and M 101. and an image of M 101 at 100m.

photometric mapping with isophot using the p32 astronomical observation template
arXiv: Astrophysics, 2002Co-Authors: R Tuffs, Carlos GabrielAbstract:The ``P32'' Astronomical Observation Template (AOT) provided a means to map large areas of sky (up to 45x45 arcmin) in the FIR at high redundancy and with sampling close to the Nyquist limit using the ISOPHOT C100 (3x3) and C200 (2x2) detector arrays on board ISO. However, the transient Response Behaviour of the Ga:Ge detectors, if uncorrected, can lead to severe systematic photometric errors and distortions of source morphology on maps. Here we describe the basic concepts of an algorithm which can successfully correct for transient Response artifacts in P32 observations. Examples are given demonstrating the photometric and imaging performance of ISOPHOT P32 observations corrected using the algorithm.

employee emotional Response toward healthcare organization s service recovery efforts and its influences on service recovery performance
Service Business, 2012Co-Authors: Sangman KimAbstract:Previous studies on service recovery performance of frontline employees have focused primarily on the direct relationship with the organizational efforts for service recovery. However, based on the reformulation of attitude theory (appraisal-emotional Response-Behaviour), we believe that the emotional Responses (work engagement and burnout) toward organizational efforts for service recovery of frontline employees mediate the relationship. Thus, the purpose of this study is to examine how healthcare frontline employees show their emotional Response toward the organizational efforts for service recovery and it influence on actual recovery performance. This study uses two conflicting emotional Responses, burnout and work engagement, to examine how employees react toward organizational efforts, helping better understand employees’ evaluations of the efforts. Research model and hypothesis were tested using a sample of frontline employees who perform none-clinical activities in hospitals. The results showed that teamwork and empowerment have positive effects on work engagement. In addition, customer complaint management, empowerment, and teamwork influenced negatively on burnout. Lastly, work engagement and burnout showed statistically significant impact of service recovery performance of frontline employees. Among the organizational efforts for service recovery, teamwork was the most important factor in improving frontline employees’ work engagement and lessened their burnout, respectively. Interestingly, customer service training had a negative effect on burnout. Besides, by comparing our research model to two alternative models, we confirmed the validity of the research model.

The effect of norm-based messages on reading and understanding COVID-19 pandemic Response governmental rules
2020Co-Authors: Bilancini Ennio, Boncinelli Leonardo, Capraro Valerio, Celadin Tatiana, Di Paolo RobertoAbstract:The new coronavirus disease (COVID-19) threatens the lives of millions of people around the world, making it the largest health threat in recent times. Billions of people around the world are asked to adhere to strict shelter-in-place rules, finalised to slow down the spread of the virus. Appeals and messages are being used by leaders and policy-makers to promote pandemic Response. Given the stakes at play, it is thus important for social scientists to explore which messages are most effective in promoting pandemic Response. In fact, some papers in the last month have explored the effect of several messages on people's intentions to engage in pandemic Response Behaviour. In this paper, we make two contributions. First, we explore the effect of messages on people's actual engagement, and not on intentions. Specifically, our dependent variables are the level of understanding of official COVID-19 pandemic Response governmental informative panels, measured through comprehension questions, and the time spent on reading these rules. Second, we test a novel set of appeals built through the theory of norms. One message targets the personal norm (what people think is the right thing to do), one targets the descriptive norm (what people think others are doing), and one targets the injunctive norm (what people think others approve or disapprove of). Our experiment is conducted online with a representative (with respect to gender, age, and location) sample of Italians. Norms are made salient using a flier. We find that norm-based fliers had no effect on comprehension and on time spent on the panels. These results suggest that norm-based interventions through fliers have very little impact on people's reading and understanding of COVID-19 pandemic Response governmental rules

Thermo- and pH-responsive polymers in drug delivery
Advanced Drug Delivery Reviews, 2006Co-Authors: Dirk SchmaljohannAbstract:Stimuli-responsive polymers show a sharp change in properties upon a small or modest change in environmental condition, e.g. temperature, light, salt concentration or pH. This Behaviour can be utilised for the preparation of so-called 'smart' drug delivery systems, which mimic biological Response Behaviour to a certain extent. The possible environmental conditions to use for this purpose are limited due to the biomedical setting of drug delivery as application. Different organs, tissues and cellular compartments may have large differences in pH, which makes the pH a suitable stimulus. Therefore the majority of examples, discussed in this paper, deal with pH-responsive drug delivery system. Thermo-responsive polymer is also covered to a large extent, as well as double-responsive system. The physico-chemical Behaviour underlying the phase transition will be discussed in brief. Then selected examples of applications are described. © 2006.
