Fitness Application

We introduce an approach that supports researchers and practitioners to determine the quality of first-time user experience (FTUX) and long-term user experience (LTUX), as well as to identify critical issues with these two types of UX. The product we chose to study is a mobile fitness application. Mobile apps tend to have a much shorter service life than most other products; thus, the developers/designers need to pay great attention to both first-time and long-term user experience. This study is based on a multi-method approach. We employed the AttrakDiff questionnaire to assess users’ first impressions of the app, and the UX Curve method to evaluate how users’ experience of the app has changed over time. Besides the quantitative data, which helped to determine the quality of user experience, we also collected qualitative data during two interviews with participants, and focused on the issues that predominantly deteriorated user experience. A four-coordinate plane tool was designed later in the data analysis process that combined the two kinds of user experience data at the same time, which led to a qualitative positioning of the user experience status of a certain product. The model was further successfully adopted in the identification of user experience issues of an online fitness application.

Time Extrapolation

We present a technique of MUF real-time forecast based on time extrapolation for maximum observed frequencies smoothed over a long-term forecast along a given path. We have validated the technique of fitting current data from the long-term forecast, using the OPEMI model, transmission curve method for short paths, and method of normal waves for long paths (over 2000 km). This technique has been tested using data obtained at the chirp sounding network of ISTP SB RAS during periods of strong and weak solar activity. The quality of the forecast has been found to significantly improve in comparison to the long-term forecast, with advance intervals of real-time forecast from 15 to 30 min. The sessions, in which the real-time forecast error is less than 10 % for 15-min advance interval, comprise from 67 to 96 % of all sessions depending on season and radio path orientation.

<p class="abstract"><strong>Background:</strong> Dysphagia is a serious sequel of head and neck cancer (HNC) and its treatment. This dysfunction is frequent and likely underreported by clinical exam. It seems necessary to assess its global burden during the pre, per and post treatment periods (up to 18 months), regardless of the treatment received.</p><p class="abstract"><strong>Methods:</strong> This was a prospective cohort study assessing the rate of dysphagia in first-time treated HNC patients, using the deglutition handicap index questionnaire (DHI) and the clinician reporting. Time to occurrence, severity and length of the dysfunction were recorded. The benefit of an evaluation by the patient himself was investigated.  </p><p class="abstract"><strong>Results:</strong> Of 134 evaluable patients: 22 were treated by surgery alone (16.4%), 16 by radiotherapy (RT) alone (11.9%), 3 by chemotherapy (CT) alone (2.2%), 28 by RTCT (20.9%), 31 by induction chemotherapy followed by RTCT (23.1%), 11 by surgery+RT (8.2%) and 23 by surgery+RTCT (17.2%). Patients completed 87.9% of the expected DHI. The dysphagia frequency reported was 92.2% by patient-reporting and 80.9% by clinicians-reporting, whatever the intensity. Self-perceived moderate to severe dysphagia was reported in 69.8% of patients.</p><p class="abstract"><strong>Conclusions:</strong> Given the strong impact of dysphagia on the quality of life and prognosis of HNC patients, it appears essential to perform screening and systematic monitoring. Using a simple and well accepted questionnaire, such as DHI, which is also well correlated with clinical evaluation, we demonstrated a significant frequency of dysphagia. The use of real-time patient-reported outcomes for its early detection would be an asset, particularly during long-term follow-up.</p><p class="abstract">Registered under ClinicalTrials.gov Identifier no.

Political parties are a vital element in the quality of representative democracy, playing a crucial role in mobilization, competition, governance, and accountability. Despite their importance, however, we currently know relatively little about how political parties in Africa are organized, with most evidence restricted to journalistic accounts or country-specific scholarly accounts. This symposium, which comes out of a conference on political parties held at the University of Cape Town, takes a closer look at the development of party structures and organization across the continent. It seeks to answer a number of critical questions including: What affects the organizational structure of parties? How do party primaries affect party-building and electoral success? And what effect does the shrinking of open political space have on the ways in which parties organize? Taken as a whole, this issue brings together established and emerging scholars, to systematically explore, for the first time, what party organization looks like on the African continent, and how it affects critical issues of governance, mobilization, and accountability.

The pressures on the health workforce have a profound impact on the quality of care. The solution to health workforce issues is a global concern and governments and health systems around the world are seeking solutions to the problems of worker shortages and access to health services. Education and training of more doctors, nurses, and other health professionals require long-term policy changes, funding, and infrastructure development. Telehealth has been identified as an alternative solution to address some of these critical issues and this chapter outlines the potential of telehealth to address some challenges facing the health workforce. The discussion will provide evidence for feasible and effective adoption of telehealth solutions.

Paclitaxel Treatment

The impact of sex in the development of long-term toxicities affecting the quality of life of cancer survivors has not been investigated experimentally. To address this issue, a series of neurologic and cardiologic endpoints were used to investigate sex-based differences triggered by paclitaxel treatment and radiotherapy exposure. Male and female wild-type (WT) mice were treated with paclitaxel (150 and 300 mg/kg) administered weekly over 6 weeks or exposed to 19 Gy cardiac irradiation. Cohorts were analyzed for behavioral and neurobiologic endpoints to assess systemic toxicity of paclitaxel or cardiovascular endpoints to assess radiotherapy toxicity. Interestingly, female WT mice exhibited enhanced tolerance compared to male WT mice regardless of the treatment regimen. To provide insight into the possible sex-specific protective mechanisms, rhoB-deficient animals and elderly mice (22 months) were used with a focus on the possible contribution of sex hormones, including estrogen. In females, RhoB deficiency and advanced age had no impact on neurocognitive impairment induced by paclitaxel but enhanced cardiac sensitivity to radiotherapy. Conversely, rhoB-deficiency protected males from radiation toxicity. In sum, RhoB was identified as a molecular determinant driving estrogen-dependent cardioprotection in female mice, whereas neuroprotection was not sex hormone dependent. To our knowledge, this study revealed for the first time sex- and organ-specific responses to paclitaxel and radiotherapy.

AbstractThis paper introduces for the first time the equal intercept transformation radar chart—an improved form—to the assessment of soil environmental quality of Nanling commodity grain base. The equal intercept transformation radar chart, a visual graphical data analysis method, translates data from a numerical to graphical format. This visualization enables data presentation, analysis process and results stick out a mile and is capable of fully retaining information contained in data and excavating it in depth from geometry. Moreover, it overcomes pertinently the main defect of the conventional radar chart that the evaluation result depends heavily on the order of arrangement of indicators. The results indicated that the soil environmental quality at depths of 0–60 cm in the low mountain area of the Nanling commodity grain base was the second grade, while that in the hilly and plain areas were both first grade. The indicators of poor soil environmental quality in the low mountain area were exogenous Cd and endogenous As; those in the hilly area were exogenous Cd and endogenous As and Hg; and that in the plain area was exogenous Cd. The results were in line with the actual situation of the study area.

The aim of the work is to evaluate the effectiveness of the risk communication strategies in cases of unsafe drinking water supply in Sardinia, the Italian context with the highest population distrust in drinking water safety. During the period 2010–2015, the ordinances published on the institutional websites were analyzed, and the population risk perception was evaluated by applying, for the first time in public health threats, the “OUTRAGE Prediction & Management” software released by Sandman. Overall, 417 ordinances issued by the Sardinian Municipalities were found. Only 1.5% of the ordinances reported information about parameters, concentrations, and risks to health, whereas 4.8% indicated only the parameters and non-standard levels. By contrast, 53.2% specified only the non-standard parameter, and 40.5% indicated a generic non-drinking motivation. The outrage assessment showed values exceeding the threshold of risk acceptance, attributable to the lack and low clarity of the information reported by the ordinances. The present study allowed us to highlight critical issues in risk communication of the quality of drinking water.

BackgroundWhen new mothers do not understand how to interact with their newborn babies, they would increase anxiety, even decrease the quality of parent-infant interactions. Previous studies indicate that the postpartum parenting education for first-time-mothers can improve the quality of mother-infant interactions in first two months. This study aimed to evaluate the long-term effectiveness of parenting education for postpartum women during the first year.MethodsThe study recruited 81 healthy first-time-mother infant dyads from the medical center in Taipei city. The experimental and control groups received extra education by way of a 40-minute videotape and normal postpartum care, respectively. Data from around first week (T1), followed by the third (T2), sixth (T3), ninth (T4), and twelfth (T5) month postpartum are collected. Assessment scales such as the Edinburgh perinatal depression scale (EPDS), the Chinese version of the parenting sense of competence scale (C-PSOC), and the Nursing child assessment teaching scale (NCATS) used for videotaped mother-infant interactions measurement were used in the study.ResultsThe analytical results show that the quality of mother-infant interaction increased at T2, T3, T4, and T5 in the experimental group (Fig. 1). No different change in maternal sense of competency was found in the experimental and control groups from T1 to T4. However, a positive change in sense of parenting competency at T5 was found in the experimental group (Fig. 2). No difference in postpartum depression was found between the two groups (Fig. 3).ConclusionsThe first-time-mothers parent education has long-term effectiveness in the mother-infant dyad interaction quality.Disclosure of interestThe authors have not supplied their declaration of competing interest.
