The service recovery paradox phenomenon has emerged as a significant effect in the services marketing literature because it is an opportunity to achieve higher levels of customer satisfaction and consequently, higher levels of loyalty. The purpose of this study is to explore and discuss the impact of customers' complaints and their treatment by the service provider in the commercial relationship after the occurrence of a service failure. This study assesses customers' behavior instead of behavioral intentions through a firm's call center database which differs from the previous studies, broadening our knowledge about service recovery paradox phenomenon and helping us to identify factors contributing to its existence. The overall results confirm the existence of the service recovery paradox in this setting and indicate critical variables influencing this phenomenon, namely the recovery timeliness, the customers' age and the failure context (failure type and failure severity). The research presents theoretical and managerial contributions. It produces an understanding of the service recovery paradox phenomenon, bringing a new approach to the analysis of customers' responses, allowing managers a better complaint management. Further research may explore the relevance of service recovery paradox in a …
Image Coding by Samples of Counts as an Imitation of the Light Detection by the Retina

: The results of the study of a new method of image coding based on samples of counts are presented. The method is based on the concept of an ideal image, motivated by the mechanisms of light perception by the retina. In this regard, the article discusses general statistical issues of the interaction of radiation with matter and based on a semiclassical approach, formalizes the concepts of an ideal imaging device and an ideal image as a point Poisson 2D-process. At the centre of the discussion is the problem of reducing the dimension of an ideal image to a fixed (controlled) size representation by a sample of counts. The results of illustrative computational experiments on counting representation/coding of digital raster images are also presented.
Reconfigurable monopole antenna for WLAN/WIMAX applications

In this paper, a simple reconﬁgurable monopole antenna for WLAN/WiMAX application is presented. The proposed antenna has been designed and compared to a three patch strips triple band monopole antenna which operate at 2.45GHz, 3.5GHz and 5.8GHz frequency bands. The antenna has been simulated using CST software studio and fabricated on FR4 substrate. The proposed antenna provides triple bands in which the bandwidth of 367MHz for 2.45GHz, 799MHz for 3.5GHz and a bandwidth of 3.47GHz for 5.8GHz has been obtained. The results show that the measured and simulated return loss characteristic of the optimized antenna satisﬁes the requirement of the 2.4/5.8GHz WLAN and 3.5GHz WiMAX antenna application. The proposed reconﬁgurable antenna is low proﬁle, compact and small in size and show good performance for WLAN/WiMAX bands. There is good agreement between the measurement and simulation results in terms of return loss and radiation pattern.
Cognitive Rigidity, Habitual Tendencies, and Obsessive-Compulsive Symptoms: Individual Differences and Compensatory Interactions

Recent theories have posited a range of cognitive risk factors for obsessive-compulsive disorder (OCD), including cognitive inflexibility and a maladaptive reliance on habits. However, empirical and methodological inconsistencies have obscured the understanding of whether inflexibility and habitual tendencies indeed shape OCD symptoms in clinical and sub-clinical populations, and whether there are notable interactions amongst these traits. The present investigation adopted an interactionist individual differences approach to examine the associations between behaviorally-assessed cognitive flexibility and subclinical OCD symptomatology in a healthy population. It also explored the nature of the interactions between cognitive flexibility and habitual tendencies, and the degree to which these cognitive traits predict subclinical OCD symptomatology. Across two studies, including a preregistration, Bayesian and regression analyses revealed that cognitive inflexibility and compulsive habitual tendencies act as unique and independent predictors of subclinical OCD symptomatology in healthy populations. Furthermore, there was a significant interaction between cognitive rigidity and habitual compulsivity, which accounted for 49.4% of the variance in subclinical OCD symptomatology in Study 1, and 37.3% in Study 2. In-depth analyses revealed a compensatory effect between cognitive inflexibility and habitual compulsivity such that both are necessary for OCD symptomatology, but neither is sufficient. These results imply that in order to generate reliable and nuanced models of the endophenotype of OCD symptomatology, it is essential to account for interactions between psychological traits. Moreover, the present findings have important implications for theories on the cognitive roots of OCD, and potentially in the development of interventions that target both cognitive inflexibility and habitual compulsivity.

The Importance of Sleep and Circadian Rhythms for Vaccination Success and Susceptibility to Viral Infections

Sleep and circadian rhythms are closely involved in the immune system and its regulation. Here, we describe this relationship and provide recommendations regarding the influence of sleep and circadian rhythms on vaccination success. We review studies investigating how viral susceptibility is influenced by changes in immunological parameters as a consequence of sleep deprivation. Short sleep duration and poor sleep efficiency both appear to be strong factors leading to greater vulnerability. In addition, both sleep duration and the time of day of the vaccination seem to be associated with the magnitude of the antibody response after vaccination. Based on these findings, a recommendation would consist of a sleep duration of 7 h or more every night to both reduce the risk of infection and to optimize the efficacy of vaccination with respect to circadian timing. Improving sleep quality and its circadian timing can potentially play a role in preventing infection and in vaccination benefits. In conclusion, sufficient (or longer) sleep duration is important in both reducing susceptibility to infection and increasing antibody response after vaccination.
The application of resonant-mode techniques to off-line converters for the commercial market

This thesis presents the work performed by the author on the application of resonantmode techniques to commercially-orientated off-line converters. An extensive review of resonant-mode topologies leads to the development of a method of categorisation of these topologies which allows a greater comprehension of their properties. The categories of converter thus obtained are the conventional resonant converter, the quasi-resonant converter, and the gap-resonant converter. The gap-resonant converter is selected for further investigation. An analysis reveals the limited load and input voltage capabilities of this converter, and hence leads to the introduction of a pre-regulating converter to improve reliability and commercial viability. High-frequency techniques are explored and reported, and new techniques are developed in several areas in order to extend the concept of the gap-resonant converter to a realworld practical design. Subjects explored include the high speed driving of power MOSFETs, MOSFET and diode switching losses, high frequency magnetic materials and core losses, and skin and proximity effects. The techniques developed are used in the design of a 30OW, off-line converter with an input voltage range of 165V to 380V after rectification, and a ten-to-one output load range.
Synaptotagmin IV function in secretory granule maturation in neuroendocrine cells.

In neuroendocrine cells, immature secretory granules (ISGs) bud from the trans Golgi network (TGN), and then undergo a maturation process that includes ISG-ISG homotypic fusion, removal of excess membranes via clathrin-coated vesicles (CCVs) and acidification of the granules. These mature secretory granules (MSGs) can then fuse with the plasma membrane upon receiving an external signal, and finally release their content in the extracellular space. In this thesis, I will present evidence that Synaptotagmin IV (Syt IV) is one of the components involved in the regulation of granule maturation in neuroendocrine cells. Syt IV is a neuron and neuroendocrine cell-specific isoform, which belongs to the synaptotagmin family of membrane trafficking proteins. After confirming that Syt IV is localised on ISGs and absent from MSGs in PCI2 cells, I investigated whether Syt IV is involved in ISG homotypic fusion by adding the purified Syt IV cytoplasmic domain into an in vitro assay, where it functions as a dominant negative. Addition of this domain, but not a similar domain from Syt I, resulted in a dose-dependent inhibition of ISG-ISG fusion. Furthermore, I found that Syt IV binds to the ISG-SNARE Syntaxin 6 (Stx6), suggesting that the two proteins might be part of the same machinery that regulates ISG maturation. In addition, I used an in vivo approach based on the processing of secretogranin II (Sgll) into its degradation product pi8, which occurs during ISG maturation, to assay Syt IV function. I show that the Syt IV cytoplasmic domain, as well as siRNA-mediated knockdown of Syt IV inhibits Sgll processing by prohormone convertase 2 (PC2). Interestingly, PC2 is found mostly in the pro-form, suggesting that activation of PC2 is also inhibited. We conclude that Syt IV is an essential component for the process of secretory granule maturation. Lastly, I found that Syt IV binds preferentially to membrane-bound clathrin adaptor protein-1 (AP-1). This suggests that Syt IV might be sorted from maturing SGs in a complex, possibly via an ISG-SNARE protein that interacts directly with AP-1.
Low Cost Virtual Cockpits for Air Combat Experimentation

The preamble in any experimentation usually involves a stage known as “screening” (Montgomery, 2001) or “discovery” (Alberts & Hayes, 2002). In general, the idea behind this stage is to identify the major independent variables that appear to have greater influences on the measures so that subsequent stages could be more focused on the important variables. This paper describes the research in which an innovative solution for a simulation environment was found to more cost-efficiently enable air combat discovery experimentation. In essence, the investigation was to see how the limited 60 degrees field of view imposed by a single display desktop virtual cockpit system could be circumvented cost efficiently. The solution in this case was the addition of a 2D display augmentation that provides information of what would be acquired visually by the pilots up in the air. The challenge was to decide the manner in which the information will be portrayed on this display. The human factors literature provided the guiding light during the research and helped narrow the effort down to an experiment with the Frames of Reference problem, i.e. deciding whether it should be egocentric or exocentric. With these insights an experiment was designed to benchmark the performance of the solution. The performances of 6 operational pilots were compared in four environments (domed simulator, desktop with no augmentation, desktop with egocentric augmentation and desktop with exocentric augmentation.) using a full-factorial experiment design with 3 replicates each. The outcome of the experiment showed that there was no statistical difference between the performance of the domed simulator and the desktop with the egocentric augmentation.
Understanding the activities and areas of concern of elderly population: The case of Singapore

There is a clear demographic trend towards a higher proportion of elderly population in most developed countries and economies. One of the key aspects related to aging is the continuation of high quality of living for elderly population. Such a goal can be achieved when elderly people are autonomous, independent and have lower risks for their health and safety. By means of a field study and personal interviews with four subjects from the identified age group, and a survey with 105 elderly participants, we have recorded their everyday instrumental activities and areas of concern, identifying actions that may pose risks to them and hence, require care and assistance. Based on our findings, we present several possibilities of smart technologies available on the market, which could be used for assisting elderly population to live a pleasant, independent, healthy and safer life in the Singaporean context.
Synthetic Biology-Powered Biosensors Based on Crispr/Cas Mediated Cascade Signal Amplification for Precise Rna Detection

Synthetic biology enabling technologies have been harnessed to create new diagnostic technologies. However, most strategies involve error-prone amplification steps and limitations of accuracy in RNA detection. Here, a cell-free synthetic biology-powered biosensing strategy, termed as SHARK (Synthetic Enzyme Shift RNA Signal Amplifier Related Cas13a Knockdown Reaction), could efficiently and accurately amplify RNA signal by leveraging the collateral cleavage of activated Cas13a to regulate cell-free enzyme synthesis. Based on cascade amplification and tailored enzyme output, SHARK behaves broad compatibility in different scenarios. The portable device based on SHARK was successfully used as SARS-CoV-2 biosensors with high sensitivity and selectivity, and the results were highly consistent with Ct values of qRT-PCR. In addition, when combined with machine learning, SHARK performs bio-computations and thus for cancer diagnosis and staging based on 64 clinical samples. SHARK shows characteristics of precise recognition, cascade amplification and tailored signal outputting comparisons with established assays, presenting significant potential in developing next-generation RNA detection technology.
Everyday Perceiver-Context Influences on Impression Formation: No Evidence of Consistent Effects

Facial impressions (e.g., trustworthy, intelligent) vary considerably across different perceivers and targets. However, nearly all existing research comes from participants evaluating faces on a computer screen in a lab or office environment. We explored whether social perceptions could additionally be influenced by perceivers’ experiential factors that vary in daily life: mood, environment, physiological state, and psychological situations. To that end, we tracked daily changes in participants’ experienced contexts during impression formation using experience sampling. We found limited evidence that perceivers’ contexts are an important factor in impressions. Perceiver context alone does not systematically influence trait impressions in a consistent manner—suggesting that perceiver and target idiosyncrasies are the most powerful drivers of social impressions. Overall, results suggest that perceivers’ experienced contexts may play only a small role in impressions formed from faces.
Fish metabolome from sub-urban lakes of the Paris area (France) and potential influence of noxious metabolites produced by cyanobacteria

The recent democratization of high-throughput molecular phenotyping allows the rapid expansion of promising untargeted multi-dimensional approaches (e.g. epigenomics, transcriptomics, proteomics, metabolomics, …). Indeed, these emerging omics tools, processed for ecologically relevant species, may present innovative perspectives for environmental assessments, that could provide early warning of eco(toxico)logical impairs. In a previous pilot study (Sotton et al., Chemosphere 2019), we explore by 1H NMR the bio-indicative potential of metabolomics analyses on the liver of 2 sentinel fish species (Perca fluviatilis and Lepomis gibbosus) collected in 8 water bodies of the peri-urban Paris’ area (France). In the present study, we further investigate on the same samples the great potential of high-throughput UHPLC-HRMS/MS analyses. We show that the LC-MS metabolome remarkably allows clear separation of individuals according to the species, but also according to their respective sampling lakes. Interestingly, similar variations of Perca and Lepomis metabolomes occur locally indicating that site-specific environmental constraints drive the metabolome variations beyond the obvious genetic differences between the two species, and seem to be influenced by the production of noxious metabolites by cyanobacterial blooms in certain lakes. Thus, the development of such reliable environmental metabolomics approaches is constituting an innovative bio-indicative tool for ecological stress assessment, such as toxigenic cyanobacterial blooms, and aim at being further follow up.
Socio-Environmental Conflicts in the Limits of Natural Parks in Africa: Characterization and Strategies for the Resolution of Conflicts Between Communities and Wild Animals in Kibale National Park - KNP- Uganda

Kibale National Park KNP is a park located in the western part of Uganda, where there is great interest by foreign tourists to visit the populations of chimpanzees (Pan troglodytes) that live there. The park is located within a matrix of the landscape, where there are many human settlements of rural populations, in which there are agricultural activities, in small-scale, as the ones that the communities have for their subsistence, and large-scale as the tea plantations. For this work, the KNP conflict registry matrix from 2008-2017 was used. For the study period, it was found that for the five (5) districts surrounding Kibale Park, 60% of the incidents were recorded in the Kabarole district. In terms of conflict, approximately 15 wild animals were with which there were incidents where it was found that 93% of the incidents were with elephants.
Visual Aids for Landing in Bad Visibility with Particular Reference to the Transition from Instrument to Visual Flight

It has been known for many years that in bad visibility the transition from instrument to visual flight is difficult, and may be highly dangerous if the pilot is suffering from fatigue, but it is only in the last five years or so that the problem of finding patterns for the visual aids which would make the transition easy and safe has been systematically studied. This paper describes some of the illusions which occur at transition and shows that they can be largely prevented by using bars of lights running transversely across the approach zone. A brief account is given of the results which have been obtained on the Crossbar System of Approach Lighting under operational conditions. A new theory of visual judgment, known as the “parafoveal streamer” theory is described, and from this the characteristics which are desirable in the visual aids are deduced. The crossbar and slopeline systems of approach lighting are compared in the light of this theory, and it is concluded that the ordinary run of pilots will find the crossbar system easier to use because the mental processes necessary for its interpretation are those which the pilot has built up in good weather flying. It is emphasised that in the absence of any coherent theory of how visual judgments are made, it is almost impossible to evaluate the various systems in a reasonable time, and that if international standardisation is to be achieved, some theory must eventually become generally accepted.
Deep Neural Network for Estimating Value of Quality of Life in Driving Scenes

The purpose of this research is to estimate a value of Quality of Life (QoL) of an image in a driving scene from only the image. The system suggesting optimal transpor tati n methods and routes from a current place to a destination has been developed. The QoL value is used for the system. A method to estimate the QoL value easily is needed. This paper proposes a method for esti mating the QoL value of the image. The image is segmented by a semantic segmentation method based on the D eep Neural Network (DNN). The rates of the total amount of the object region of each object class to the w ole image region are calculated. The rates are used as indicators for estimating the QoL value. The MultiLa yer Perceptron (MLP) learns the relationship between the QoL value and the rates. The DNN for estimating th e QoL value from only the input image is constructed by connecting the DNN based semantic segmentat ion model and the MLP. The effectiveness of the proposed method is demonstrated by the experiments.
