Effect of Rosa damascena Oil Aromatherapy on Fatigue Severity in Patients Receiving Hemodialysis: A Randomized Controlled Trial

Objectives: The prevalence of fatigue in patients receiving hemodialysis is high. This study aimed to investigate the effect of Rosa damascena oil on fatigue severity in patients receiving hemodialysis. Materials and Methods: This randomized controlled trial was performed on 74 patients receiving hemodialysis in Tabriz, Iran from January 21 to February 21, 2019. The patients were conveniently recruited and assigned into two groups of intervention and control using a block randomization method with block sizes of four and six and a sequence of 1:1. Patients in the intervention group were trained to inhale three drops of R. damascena oil each night for one month. We used the Fatigue Severity Scale (FSS) for data collection and analyzed the data using the independent samples and paired t tests. Results: No significant difference was found between the two groups respecting the mean baseline fatigue scores (P=0.12). However, at the end of the study, the mean fatigue score was significantly lower in the intervention group compared to the control group (P=0.001). Conclusions: We witnessed that R. damascena oil aromatherapy significantly reduced the severity of fatigue in patients receiving hemodialysis. This useful and inexpensive technique can be utilized as a complementary method to relieve fatigue in patients receiving hemodialysis.

When and how information and communication technology orientation affects salespeople’s role stress: the interplay of salesperson characteristics and environmental complexity

Purpose As empirical insights into when salespeople should integrate information and communication technology (ICT) into their sales tasks are limited, the purpose of this study is to investigate the impact of salespeople’s ICT orientation on role stress by considering the interplay of individual salesperson characteristics and the complexity of the selling environment, differentiating between customer and supplier complexity. Design/methodology/approach The authors develop an empirical framework based on the Job Demands-Resources model and previous research in the area of technology in sales. They test their hypotheses by means of a survey of 255 business-to-business salespeople which is analyzed using ordinary least squares regressions. Findings The results of this study show that ICT orientation generally helps salespeople to reduce role ambiguity. However, the benefits salespeople derive from ICT orientation to reduce role conflict depend on an interplay of both their job tenure and the average relationship duration with customers as well as the complexity of the selling environment. Originality/value This study contributes to research on the impact of technology use on salespeople by enhancing the understanding of contexts that make ICT valuable for them. In particular, the findings of this study demonstrate that the impact of ICT orientation on salespeople’s role stress depends on an interplay of individual salesperson characteristics, that is, resources, and environmental complexity characteristics, that is, demands.
The Effects of Cucumber Mosaic Virus and Its 2a and 2b Proteins on Interactions of Tomato Plants with the Aphid Vectors Myzus persicae and Macrosiphum euphorbiae

Cucumber mosaic virus (CMV), a major tomato pathogen, is aphid-vectored in the non-persistent manner. We investigated if CMV-induced volatile organic compounds (VOCs) or other virus-induced cues alter aphid–tomato interactions. Y-tube olfactometry showed that VOCs emitted by plants infected with CMV (strain Fny) attracted generalist (Myzus persicae) and Solanaceae specialist (Macrosiphum euphorbiae) aphids. Myzus persicae preferred settling on infected plants (3 days post-inoculation: dpi) at 1h post-release, but at 9 and 21 dpi, aphids preferentially settled on mock-inoculated plants. Macrosiphum euphorbiae showed no strong preference for mock-inoculated versus infected plants at 3 dpi but settled preferentially on mock-inoculated plants at 9 and 21 dpi. In darkness aphids showed no settling or migration bias towards either mock-inoculated or infected plants. However, tomato VOC blends differed in light and darkness, suggesting aphids respond to a complex mix of olfactory, visual, and other cues influenced by infection. The LS-CMV strain induced no changes in aphid–plant interactions. Experiments using inter-strain recombinant and pseudorecombinant viruses showed that the Fny-CMV 2a and 2b proteins modified tomato interactions with Macrosiphum euphorbiae and Myzus persicae, respectively. The defence signal salicylic acid prevents excessive CMV-induced damage to tomato plants but is not involved in CMV-induced changes in aphid–plant interactions.
The Effect of the Combination Stimulation Cutaneous and Virgin Coconut Oil on the Sleep Quality and Comfort level in People Undergoing Hemodialysis

Introduction: Sleep quality can be disruptive in patients with chronic illness, especially in patients with Chronic Renal Failure (CRF). In recent times, CRF was associated with poor sleep quality, about 25-36% of the normal adult population had sleep disorders. However, the prevalence of sleep disturbance in patients with uremia undergoing of hemodialysis occurs about 40-85% higher than the general population. It was reported that the majority of cases of chronic renal failure are people who lack sleep. Sleep disorders are very common in patients with chronic kidney disease. Poor sleep in hemodialysis patients has a negative impact on the physical and mental components of a person's life and leads to a decrease in their performance as well as cognitive and memory dysfunction. Methods: A queasy-experiment with pretest-posttest control group design. The sampling method is used simple random sampling, conducted between January-February 2018. A total of 52 patients undergoing hemodialysis divided randomly into two groups. The treatment group was given cutaneous stimulation and VCO for 4 weeks and the control group was not given cutaneous stimulation and VCO. Results: Giving cutaneous stimulation and VCO effective in improving sleep quality and comfort level. There were significant results on sleep quality seen from Mann Whitney test with p <. 001 and comfort level from Mann Whitney test with p = 0.009. Conclusion: Provision of cutaneous stimulation and VCO can be used as complementary therapy in improving quality of sleep and comfort in patients undergoing hemodialysis.

Determinants of organic wine production: An application in the DOC Rioja wine industry

Aim of study: To analyse the role that valuable resources and agglomeration would play in the decision to produce organic wines. Area of study: The Controlled Designation of Origin (DOC) Rioja wine industry in Spain, the leading qualified denomination of origin of Spain. Material and methods: Taking into account the nature of the dependent variable, a binomial logit model was used. Main results: This paper confirms the significance of valuable resources such as financial resources and human resources, but also of knowledge-based spillovers from proximate organic wineries in improving the probability of producing organic wines. Contrary to expectations, technological resources and experience in the wine industry have no significant effect. Research highlights: The resource based-view and the cluster approach are complementary to improving the predictive elements of producing organic wine in the DOC Rioja wine industry. The authors were unable to pre-register the analysis involving primary data collection before the data collection exercise starts. This requirement is from January 2022 and the survey period of this paper was on 2017. According to the editorial policy of the journal this analysis should be considered exploratory.
Self-Tuning Sliding Mode Control for an Uncertain Coaxial Octorotor UAV

Sliding mode control (SMC), which is well known to its insensitivity to parameter uncertainties and robustness against various disturbances, has been widely adopted for some types of underactuated systems, including multirotor unmanned aerial vehicles (UAVs). This article is absorbed in developing a self-tuning SMC strategy to perform the robust and adaptive tracking control for an uncertain coaxial octorotor UAV (COUAV) with the actuator faults. Such a strategy is composed of manifold coefficients, which are adjusted by employing gradient descent method. It is also composed of continuous controllers that are designed by utilizing the radial basis function neural network (RBFNN) to approximate the total disturbances, where the approximation errors of RBFNN are estimated by using the adaptive control method. Moreover, the developed SMC strategy allows tuning the adaptive coefficients of the constructed manifolds, eliminating the inherent chattering phenomenon, and addressing the robust and adaptive tracking control problems for an uncertain COUAV. Comparative simulation results are carried out to illustrate the effectiveness of the developed SMC strategy.
The Role of Common and Specific Factors in Child Psychodynamic Psychotherapy: A Grouped Cases Study

ABSTRACT There is a growing evidence-base that suggests the effectiveness of the psychodynamic therapies for children, but the mechanisms by which the results are achieved still demand clarification. This study aimed to analyze the role of specific and common factors in the process of psychodynamic psychotherapy for school-age children and their association with psychotherapies outcomes. A longitudinal, repeated-measures design, based on the systematic case-study method was adopted. 204 sessions from four child psychotherapies were analyzed in terms of the therapists’ techniques, the therapeutic alliance, the use of the reflective functioning approach and the role of the symbolic play in the sessions. The outcomes were assessed based on mothers’ reports about children’s symptomatic improvement. Correlational, discriminant and regression analyses were used to examine the associations and the role of each factor in those therapeutic processes. The results indicated that the use of psychodynamic techniques and a stronger therapeutic alliance impacted more significantly the symptomatic improvement. The factor that presented more changes over time was the therapeutic alliance, increasing in two cases and decreasing in one of them, which did not show clinically significant symptomatic improvement. Common and specific factors walked together in these treatments, and both were important to produce clinically significant improvements.
Zoo Closure Does Not Affect Behavior and Activity Patterns of Palawan Binturong (Arctictis binturong whitei)

Exploring the interaction between humans and animals has become increasingly important in the evaluation of well-being for species housed in zoos and aquaria. The COVID-19 pandemic saw the global closure of zoos and aquaria to visitors. Chester Zoo, U.K., was no exception, with the charity shutting its doors for the longest period in its 90-year history. Whilst access to site was strictly limited to essential animal care staff, recent investment in networked infrared CCTV camera systems allowed some species to be monitored remotely during this extraordinary period of zoo closure. Here, we used this equipment to investigate whether zoo closure influenced activity patterns and behavior of two adult Palawan binturong, Arctictis binturong whitei. The cameras facilitated behavioral monitoring over 24 h enabling the collection of a full activity budget, which revealed a natural crepuscular activity pattern. Overall, visitor presence was found to have a neutral effect on this species, with no significant difference observed in time spent engaging in den use, vigilance or travel behaviors during zoo open and zoo closed conditions. A neutral visitor effect was found when evaluating behavior over a 24 h period and during hours which the zoo would normally be open to visitors (10:00–16:30). This research presents new information on this elusive and understudied species in captivity, and promotes investment in monitoring equipment which enables more comprehensive behavioral sampling than traditional visitor-effect methods.
Examining the bipolarity of the Minnesota multiphasic personality inventory-2-restructured form (MMPI-2-RF) behavioral / externalizing dysfunction (BXD) scale using a laboratory measure of impulsivity

Abstract This study sought to test if trait levels of impulsivity were related in a nonmonotonic manner to success on a laboratory task of impulsivity. Participants completed the MMPI-2-RF, a self-report measure of psychopathology, and the Angling Risk Task (ART), a laboratory measure of impulsivity. Variables of interest were T-scores on the MMPI-2-RF scale Behavioral/Externalizing Dysfunction (BXD) and total money earned on the ART, which was conceptualized as a measure of success on the task. After screening, the sample consisted of 173 undergraduate students. The findings showed no evidence to support a nonmonotonic relationship between BXD scores and success on the Angling Risk Task when tested by (1) polynomial regression, and (2) the two lines test, a procedure recently developed to detect nonmonotonicity. Results do not support the hypothesis of an optimal level of impulsivity, at least in a nonclinical population and with a laboratory operationalization of impulsivity. Future studies should examine this question in samples with greater variability and using more consequential operationalizations of impulsivity.
Retrieval of photoionization group delay in chirped-attosecond pulses photoelectron streaking experiments

Photoionization time delays have been investigated in many streaking experiments in which an extreme ultraviolet (XUV) attosecond pulse is used to ionize the target in the presence of a dressing infrared laser field. The discrepancies between the photoionization time delays thus experiment measured and those from many sophisticated theoretical simulations have generated a great deal of controversy in recent years. The difficulty of achieving an accuracy of the retrieved time delays comes from two facts: a so-called wavepacket approximation is introduced to construct the photoionization electron wavepacket, this approximation is invalid if atto-chirp of XUV is non-zero; the other one is that the lower sensitivity of the streaking spectra to the phase of the photoionization transition dipole. Here we present a time delay retrieval method born from our recently proposed ‘phase retrieval of broadband pulses auto correlation’ (PROBP-AC) technology to overcome above limitations. We carefully exam the validity of our method and make a few compare with some other common used retrieval codes, and the simulations demonstrate that more accurate results can be retrieved using PROBP AC. Based on the present method, the angular dependent photoionization time delays can also be retrieved. Our investigation casts doubts on the measured group time delays in previous streaking experiments. We also mention here that a single photoionization group time delay at the XUV peak energy is not enough to represent a complete photoemission process; instead, a fully characterization of the photoionization group time delay over the whole bandwidth of the wave packet is required.
Schadenfreude and sympathy following President Trump’s COVID-19 diagnosis: Influence on pre-election voting intentions

Schadenfreude and sympathy are often experienced at the intergroup level; however, little research has been conducted to examine their role in one of the most prominent and emotionally evocative intergroup contexts: the political arena. In this study, we assessed a sample of 506 Americans’ (Age M = 41.69 years, SD = 13.94; 57% women) schadenfreude and sympathy (and related cognitions) in response to then-President Trump’s COVID-19 diagnosis (a salient misfortune of a contentious political figure), and how their schadenfreude, sympathy, and related cognitions were associated with shifts in voting intentions (own and public’s) in the 2020 Presidential Election. We also examined trends in, and associations between, these variables by political affiliation (focusing on Democrats and Republicans) and gender (focusing on men and women). Unsurprisingly, compared to Republicans, Democrats expressed more schadenfreude and less sympathy. Contrary to previous research, however, Democrats’ experiences of schadenfreude were tempered and were primarily driven by deservingness beliefs rather than intergroup competition or malice). Amongst Republicans only, men experienced stronger schadenfreude than women. Regarding voting intentions, participants were more likely to report that the diagnosis would impact shifts in the public’s voting than their own voting, primarily in favor of the Democratic Party. Feelings of schadenfreude and sympathy were not significantly associated with anticipated shifts—rather, those who believed then-President Trump’s diagnosis was deserved (cognition strongly associated with schadenfreude) were four times more likely to believe the public would change their vote to the Democratic Party. These findings are discussed in relation to research at the intersection of psychology and political science and have implications for politicians and psychologists who aim to understand emotions underlying partisanship and voting behavior.
Deep band modulation, frequency discrimination, temporal resolution and audibility effects: phrase perception with and without hearing impairment among older adults

Abstract Objective The temporal envelope enhancement using deep band modulation (DBM) exaggerates the temporal peaks and valleys in the speech signal, thereby reducing the difficulty in the perception of speech in noise. Method Ten participants in each group of older adults with and without hearing loss in 65 to 83 years were recruited. A repeated measures research design was utilised to investigate phrase perception in unprocessed and deep band modulated phrases at different signal-to-noise (SNR) ratios (−4, 0, and +4). Temporal processing, spectral discrimination and speech intelligibility index were assessed. Results Regardless of the group, the phrase perception in the deep band modulated condition was significantly better than the unprocessed condition at each SNR. A significantly strong negative correlation was observed between: Gap detection threshold (GDT) and phrase perception scores in unprocessed condition at −4 dB SNR in each group; frequency difference limen in each condition and DBM phrase perception at −4 dB SNR in the older adult group with hearing impaired (OAG-HI) group. Furthermore, audibility reflected in the speech intelligibility index (SII) did not influence phrase recognition irrespective of condition, SNRs and group. Conclusion Increased modulation depth enables the participants to use the available temporal envelope, especially at the portion of the phrase where noise is less energetically masked.
Geomagnetically induced currents in a power grid of northeastern Spain

Using the geomagnetic records of Ebro geomagnetic observatory and taking the plane wave assumption for the external current source and a homogeneous Earth conductivity, a prediction of the effects of the geomagnetic activity on the Catalonian (northeastern Spain) power transmission system has been developed. Although the area is located at midlatitudes, determination of the geoelectric field on the occasion of the largest geomagnetic storms during the last solar cycles indicates amplitudes that are higher than those recorded in southern Africa, where some transformer failures on large transmission systems have been reported. A DC network model of the grid has been constructed, and the geomagnetically induced current (GIC) flows in the power network have been calculated for such extreme events using the electric field at Ebro as a regional proxy. In addition, GICs have been measured at one transformer neutral earthing of the power grid, so that there the accuracy of the model has been assessed. Although the agreement is quite satisfactory, results indicate that better knowledge of the ground conductivity structure is needed. This represents the first attempt to study and measure GICs in southern European power grids, a region considered to have low GIC‐risk up to the present.
Some new uniform approximate analytical representations of the Blasius function.

New uniform approximations of the Blasius velocity profile and Blasius function are developed from existing rational approximations of the Blasius velocity profile and of the Blasius function itself. Essentially, the existing rational approximations are rescaled (when necessary) and one of two methodologies [1, 11] is applied to the rescaled rational approximations to determine corresponding uniform approximations to the Blasius velocity profile and Blasius function. A brief discussion is presented on the merits of the results.
