RESUMO

The outbreak of the COVID-19 pandemic has had a wide range of negative consequences for higher education students. We explored the generalizability of the control-value theory of achievement emotions for e-learning, focusing on their antecedents. We involved 17019 higher education students from 13 countries, who completed an online survey during the first wave of the pandemic. A structural equation model revealed that proximal antecedents (e-learning self-efficacy, computer self-efficacy) mediated the relation between environmental antecedents (cognitive and motivational quality of the task) and positive and negative achievement emotions, with some exceptions. The model was invariant across country, area of study, and gender. The rates of achievement emotions varied according to these same factors. Beyond their theoretical relevance, these findings could be the basis for policy recommendations to support stakeholders in coping with the challenges of e-learning and the current and future sequelae of the pandemic.

RESUMO

The outbreak of the COVID-19 pandemic has dramatically shaped higher education and seen the distinct rise of e-learning as a compulsory element of the modern educational landscape. Accordingly, this study highlights the factors which have influenced how students perceive their academic performance during this emergency changeover to e-learning. The empirical analysis is performed on a sample of 10,092 higher education students from 10 countries across 4 continents during the pandemic's first wave through an online survey. A structural equation model revealed the quality of e-learning was mainly derived from service quality, the teacher's active role in the process of online education, and the overall system quality, while the students' digital competencies and online interactions with their colleagues and teachers were considered to be slightly less important factors. The impact of e-learning quality on the students' performance was strongly mediated by their satisfaction with e-learning. In general, the model gave quite consistent results across countries, gender, study fields, and levels of study. The findings provide a basis for policy recommendations to support decision-makers incorporate e-learning issues in the current and any new similar circumstances.

RESUMO

Despite of the studies on widespread biological effects of irradiation, surprisingly only little number of papers can be found dealing with its in vivo hemorheological impact. Furthermore, other studies suggested that low-dose irradiation might differ from high-dose in more than linear ways. On Balb/c Jackson female adult mice hematological and hemorheological impacts of total body irradiation were investigated 1 hour following 0.002, 0.005, 0.01, 0.02, 0.05 and 0.1 Gy dose irradiation. In case of 0.01 Gy further groups were analyzed 30 minutes, 2, 4, 6, 24 and 48 h after irradiation. According to the results, it seems that the dose-dependent changes of blood micro-rheological parameters are not linear. The irradiation dose of 0.01 Gy acted as a point of 'inflexion', because by this dose we found the most expressed changes in hematological parameters, as well as in red blood cell aggregation, deformability and osmoscan data. The time-dependent changes showed progressive decrease in pH, rise in lactate concentration, further decrease in erythrocyte aggregation index and deformability, with moderate shifting of the optimal osmolarity point and modulation in membrane stability. As conclusion, low-dose total body irradiation may cause micro-rheological changes, being non-linearly correlated with the irradiation dose.

RESUMO

Emotions are parts of organizational reality to an ever increasing extent. Importantly, they are not just tools in the hand of healthcare workers to achieve better physician / healthcare professional-to-patient interactions but intrinsic processes and characteristics with psychic, cognitive and somatic actions. For a thorough investigation of the issue, a PANAS-X questionnaire was used to examine the emotions of 187 physicians and other healthcare professionals, all engaged in oncology, in 2009. The research succeeded in exploring the overall emotional state oncology professionals had assumed in relation with their job as well as enabled the authors of this study to draw the respondents' emotional map and assess their fundamental emotional attitudes. Furthermore, the authors managed to identify groups of respondents that had felt more intense positive, and/or less intense negative emotions that are socially accepted than others. They included those of senior experienced oncologists, males, individuals with families, childless individuals, ward workers, and skilled professionals. According to the findings, the range of emotions an oncologist experiences / feels intently during his everyday work is dependent upon a great number of factors.

RESUMO

OBJECTIVE: The goal of this study was to investigate the local tumor blood supply parameters relative tumor blood volume (rTBV) and transfer coefficient (K(trans)) measurable with dynamic contrast enhanced computed tomography (DCE-CT) in patients with non-small-cell lung cancer (NSCLC) scheduled for radiation therapy (RT). MATERIALS AND METHODS: rTBV and K(trans) were measured before RT in 31 patients with clinically inoperable NSCLC (Stages I-III), which received (n=19) or did not receive (n=12) induction chemotherapy (IChT). Possible links between rTBV and K(trans) and time-to-progression (TTP), overall survival (OS) and maximum standardized uptake value (SUV(max)) from fluorodeoxyglucose positron emission tomography as well as histology were analyzed. RESULTS: NSCLC showed a wide range of rTBV and K(trans) values as estimated by DCE-CT (6.4±0.6ml/100ml and 18.2±1.5ml/100ml/min correspondingly). A significant difference in rTBV values in patients with IChT (4.6±0.6ml/100ml) and without IChT (7.5±0.9ml/100ml; p=0.023), depending on the number of cycles of the IChT and the clinical stage was found. A negative correlation between rTBV and TTP was revealed only in RT patients up-staged by FDG-PET/CT from stage III to stage IV (n=7, r=-0.96, p=0.0006). An inverse correlation between K(trans) and TTP (n=24, r=-0.53, p=0.008) was observed in all RT patients. No relevant correlation was detected between rTBV, K(trans) and SUV(max) or histologic subtypes and grading. CONCLUSIONS: Tumor blood supply parameters derived from DCE-CT are useful to characterize tumor vascularization before radiotherapy in patients with NSCLC and data on outcome prediction are supplemented.

RESUMO

BACKGROUND AND PURPOSE: Local failure is a significant issue following radiotherapy (RT) for patients with non-small cell lung cancer (NSCLC). The aim of this study was to find out whether FDG-PET/CT is capable to predict tumor relapse location in patients with NSCLC, in particular to determine high risk tumors' subvolumes responsible for local failure. MATERIAL AND METHODS: Ten patients with locoregional relapse of NSCLC underwent FDG-PET/CT before, during, and in the 4-12 months following curative chemoradiotherapy (ChRT, 66 Gy) using a combined PET/CT scanner. Morphologic and metabolic tumor volumetry and an evaluation of FDG-uptake dynamics were performed. RESULTS: CT showed partial reduction of tumor volume after RT in all patients. PET-revealed partial in eight patients and complete metabolic response in two patients during RT. Six to nine months after RT, local failure was diagnosed in all patients with both methods. Tumor recurrences were localized mostly in the most active ones of pre-therapeutically metabolic regions of the primary tumor. CONCLUSIONS: Local failure in NSCLC appears most common at the primary site and within the irradiated target volume with the highest FDG uptake. This observation may be useful for further optimization of radiotherapy of NSCLC, for example, by the application of additional radiation dose to subvolumes of primary tumors with higher FDG uptake.

RESUMO

In the course of their everyday work health care professionals (HCPs) often have to change their true feelings. The literature labels this performance as emotional labor. This article is presenting data on the characteristics of HCPs' most endangered by the negative consequences of emotional labor. Our simple choice question survey was conducted at Debrecen University Medical Healthcare Center with the help of 50 oncology HCPs volunteers. Nearly 90% of the HCPs examined change their true feelings in the course of work. It is very difficult to classify those threatened by the negative upshot of this emotional labor. Due to our research we found appalling differences of work motivation that were tightly interconnected with the respondents' emotional labor and their perceived role/emotional expectations. We succeeded in establishing three clusters and defining each cluster's characteristics. Figures suggest that only somewhat more than the half of the HCPs is authentic professional helper, and 45% of them does not or only slightly perceive the patients' demands concerning their work. Therefore, it is important that the work environment does not only assist the work of HCPs by professional means, but along emotional dimensions as well.

RESUMO

Health care professionals do not have emotional labour obligations in their employment contract. However, in everyday work it is often inevitable for them to change their true feelings. This is critically true for professionals treating chronic or cancer patients. The suitable emotional state of the treatment staff does not only influence the practitioner-patient relationship but the process of recovery as well. Depending on the way one might get into the appropriate emotional state, the literature distinguishes between surface, deep and genuine acting. While surface and deep emotional labour has numerous negative psychological consequences genuine acting is usually accompanied by positive side effects. For those working in the field of oncology, emotional labour is a part of the role expectations of the professionals. This is how the appropriate attitude is a fundamental part of the professionals' essence. For the in depth analysis of subjects related to emotional labour, the authors adopted ideas from L. Festinger 's cognitive dissonance theory. The best way to alleviate cognitive dissonance and the negative side effects of emotional labour is to prevent the emergence of them. Oncology professionals should fit their role expectations genuinely, without particular efforts. If this was impossible, or the particular life situations did not allow genuine acting, it is the employer's and the workmates' common duty to help professionals, to ease the load of emotional labour, to diminish the occurring cognitive dissonance with the help of appropriate recompense.

RESUMO

Oncologists and related health care professionals (HCPs) do not only have to follow professional protocols in their everyday work, but also have to communicate proper attitudes towards patients suffering from malignant diseases. This task is often a heavier load than the implementation of professional activities themselves. The present article is based on a survey on HCP work motivation, employment parameters and correlations with emotional labour. Fifty oncology HCPs at Debrecen University Medical Health Sciences Centre volunteered to participate in this survey containing 20 simple-choice questions. More than 90 percent of HCPs make an effort to hide their emotional state, giving way to possible negative side effects. The survey showed significant differences between the level of emotional labour of those working in the field of oncology longer or shorter than ten years. Surface and deep emotional labour is more frequent among professionals already working in oncology for a longer period of time. This can serve us with explanation to the burn-out syndrome so frequent in this profession. To diminish the load of emotional labour, healthcare institutes have to aim at hiring employees that spontaneously fit the emotional and behavioural norms facing them, and do not need officially prescribed behavioural norms for everyday work. Their constant need for respect and appreciation of their values must be kept in mind, because the capability of genuine emotional labour diminishes parallel to the number of years spent in work.
