The mediating effect of introjected motivation on the relation between perfectionism and academic burnout

Abstract Maladaptive perfectionism and controlled motivation are vulnerability factors for burnout. This study examined the relationships between two aspects of perfectionism (high standards, discrepancy), four academic motivational orientations (intrinsic, identified, introjected, extrinsic), and academic burnout. The target population was 12th graders in South Korea, and a total of 950 participants were recruited using cluster sampling. Data were collected from three waves of longitudinal study. In particular, the mediating role of academic motivation (T2) in the link between perfectionism (T1) and academic burnout (T3) was tested using structural equation modelling. The results indicated that introjected motivation mediated the relationship between perfectionism and burnout. Specifically, both high standards and discrepancy were positively associated with introjected motivation, and in turn, introjected motivation was positively associated with burnout. The theoretical and practical implications of these findings are discussed.
Effect of Reflexology in Treating Cancer Pain: A Meta-Analysis

Context: Pain is a common symptom associated with cancer and its treatment. The conventional treatment does not often relieve cancer pain optimally. The complementary therapies are increasingly used as adjunct therapy alongside pharmacological and conventional treatments in patients. Objectives: The aim of this systematic review was to investigate the existing evidence for reflexology effect on cancer pain through a meta-analysis. Data Sources: In this systematic review, electronic databases including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and PubMed were searched to find relevant studies until December 2018. Study Selection: We included before-after studies and trials of interventions that focused on pain management using reflexology modality as an intervention in patients with cancer regardless of cancer type. The effect of reflexology for patients with cancer pain was investigated as the main outcome. Data Extraction: The extracted information included name of authors, year of publication, study location, type of study, sample size, and outcome indicator. Consensus was reached by discussion in case of disagreement during each stage of selection, qualitative assessment, and extraction of data. We assessed heterogeneity using the I2 statistics. The publication bias was explored using the Egger’s and the funnel plot. We meta-analyzed the data and reported the standardized mean difference (SMD) with 95% confidence intervals (CI) using the random-effects model. Meta-analysis was done using the Revman software. Results: Eight studies with 948 participants were analyzed using a random- effects model meta-analysis. Included studies consisted of five randomized clinical trials, one quasi-experimental, and two pre-post design. We observed a positive effect for reflexology in patients with cancer pain compared with usual care (SMD- 0.55 [95% CI-0.82 to 0.21] P < 0.001). Conclusions: This systematic review provides sufficient evidence for the effectiveness of reflexology as an effective treatment in cancer pain. But we recommend conducting studies with larger sample size, well-designed trials with sufficient duration and longer follow-up periods with clear details about reflex practitioners, duration of intervention, instrument for pain assessment, and outcome. Meanwhile, patients should be adequately monitored and adverse effects should be reported. All of the aforementioned issues might affect the impact of reflexology adjuvant treatment.
Ataxia telangiectasia: A diagnostic challenge. Case report

Introduction: Ataxia-telangiectasia (AT) is a neurodegenerative syndrome with low incidence and prevalence worldwide, which is caused by a mutation of the ATM gene. It is an autosomal recessive disorder that is associated with defective cell regeneration and DNA repair mechanisms. It is characterized by progressive cerebellar ataxia, abnormal eye movements, oculocutaneous telangiectasias and immunodeficiency. Early diagnosis is critical to initiate a timely interdisciplinary treatment, improve acute symptoms, and control the multiple comorbidities of the disease. The following is the case of a patient who presented with the aforementioned characteristics and had an adequate response to the established medical treatment.Case presentation: A 7-year-old female patient from Bogotá, who presented clinical signs of global neurodevelopmental delay, cerebelar ataxia, frequent respiratory infections and ocular telangiectasias. Symptoms were associated with elevation of alpha fetoprotein and immunodeficiency, which allowed for a diagnosis of AT and the initiation of a timely interdisciplinary treatment.Conclusion: AT is a chromosomal instability syndrome with characteristic signs and symptoms. It is essential to know the etiopathogenesis, clinical manifestations, diagnostic criteria, and therapeutic options, emphasizing that early detection and clinical suspicion could favor the proper management of the comorbidities and improve the progressive course of the disease.
A sectional method to account for shear enhancement in point‐loaded nonslender members

In nonslender members, significant vertical compressive stresses occur by the loading and support conditions. Sectional models, which ignore the beneficial effects of these vertical compressive stresses underestimate the shear strength of such members. In this study, a simple expression is derived to calculate the vertical compressive stress at mid‐depth of point‐loaded nonslender beams and shear design provisions in the fib MC2010 are extended to account for the shear enhancement in nonslender members by considering this compressive stress in the equilibrium conditions. ACI‐DAfStb evaluation databases of shear tests on point‐loaded simply supported reinforced concrete members with and without stirrups are employed to evaluate the accuracy of this proposed sectional analysis method. Results show that including vertical compressive stresses in the fib MC2010 sectional shear design procedures greatly improved the accuracy of shear strength predictions for point‐loaded nonslender members.
Preparation of polypropylene/poly (butylene adipate‐co‐terephthalate) composite films incorporated with melanin for prevention of greening of potatoes

Polypropylene (PP) and poly (butylene adipate‐co‐terephthalate) (PBAT) blend films incorporated with melanin (Mel) were prepared using an extrusion casting method. Scanning electron microscopy results showed that Mel was evenly dispersed to form a well‐blended film. The PP/PBAT/Mel composite films prevented UV light transmittance, especially UV‐B rays. The addition of Mel influenced the surface color, water vapor transmission rate, oxygen transmission rate, and water contact angle of the composite films. After the addition of Mel, the tensile strength and elongation at break in the machine direction of the composite film increased by 30% and 27%, respectively. Packaging potatoes with PP/PBAT/Mel film and storing them under fluorescent light for 6 days effectively prevented the greening of potatoes caused by the production of chlorophyll. The PP/PBAT/Mel films have a high potential for the prevention of greening of potatoes during storage and distribution.
The Study on Poverty Reduction Effects of Chinese Urban Minimum Living Standard Guarantee System—Empirical Analysis Based on CHIP 2002 and 2007

The Chinese urban minimum living-standard guarantee system, mainly functions to guarantee the poor people to have minimum living-standard life; at same time it can make some people to get rid of poverty by some poverty lines. But how much of the rates can be reduced? What differences among provinces, and what impact on all kind of families? The paper tries to answer these questions by using Chinese Household Income Project (CHIP) 2002 and 2007, taking international poverty line, minimum living standard line, Martin’s poverty line and relative poverty line respectively to measure the poverty reduction impact of urban minimum living standard guarantee. On the whole, the urban minimum living standard guarantee is effective to alleviate absolute poverty and even part of relative poverty. For example, taking international poverty line as standard, in 2002 the urban minimum living guarantee respectively decreased absolute poverty rate, poverty gap and squared poverty gap of national urban area by 4.58%, 11.41% and 16.32%, while in 2007 decreased respectively by 47.24%, 70.87% and 83.04%. Taking relative poverty line as standard, in 2002 respectively poverty rate, poverty gap and squared poverty gap of national urban area decreased by 1.92%, 4.65% and 8.37%, while in 2007 the 3 indices reached by 3.28%, 11.63% and 22.57% respectively, but which are lower than by international poverty line. On the whole, according to different poverty lines and indices, the urban citizen in different provinces and families gained different poverty reduction effects brought by the urban minimum living standard guarantee.
BACTERIAL CAUSES AND ANTIMICROBIAL SENSITIVITY PATTERN OF EXTERNAL OCULAR INFECTIONS IN SELECTED OPHTHALMOLOGY CLINICS IN SANA’A CITY

Objectives: The aim of the current study was to reveal the bacterial profile and pattern of sensitivity to antibiotics for external ocular infections for patients who attended selected ophthalmology clinics in the city of Sana’a. Methods: A cross-sectional study design was used from September 2016 to October 2017 where a total of 197 patients with infection of external eye were included in the study which included conjunctivitis, keratitis, blepharitis and Blepharoconjunctivitis. Samples were collected and transferred to the National Center of Public Laboratories (NCPHL), in Sana'a. Possible bacterial pathogens have been isolated and identified using regular laboratory techniques, and microbial sensitivity testing has been carried out using a disc diffusion method. Results: A total of 197 ocular samples were obtained for microbiological evaluation, of these 146 (74.1%) have bacterial growth. Bacteria of Gram positive accounted for 52.1% and the prevalent isolation was S. aureus (30.1%). Gram negative bacteria made up 47.9% and the predominant isolation was Pseudomonas aeruginosa (26.7%). The majority of Gram-positive bacteria were sensitive to ciprofloxacin (90% 100%), vancomycin (86% 100%) and Gram-negative isolates sensitive for amikacin (100%) and ciprofloxacin (63% 100%). Conclusion: These results revealed that Gram-positive bacteria were the generally common bacteria isolated from infections of external eye and were more susceptible to vancomycin and ciprofloxacin while Gram-negative isolates were more susceptible to ciprofloxacin and amikacin. The high rate of resistance for most antibiotics in Yemen, leaves ophthalmologists with very few options of drugs to treat eye infections. Large-scale ongoing studies in the future should also be conducted in order to monitor the antimicrobial resistance of the external ocular bacterial isolates.
PHAGE-2 Study: Supplemental Bacteriophages Extend Bifidobacterium animals subsp. lactis BL04 Benefits on Gut Health and Microbiota

Probiotics are increasingly used by consumers and practitioners to reduce gastrointestinal (GI) distress and improve gut function. Here, we sought to determine whether addition of supplemental bacteriophages (PreforPro) could enhance the effects of a common probiotic, Bifidobacterium animalis subsp. lactis (B. lactis) on GI health. We conducted a 4-week, randomized, parallel-arm, double-blind, placebo-controlled trial where primary outcomes included self-assessments of GI health, a daily stool log, and 16s rRNA analysis of gut microbial populations. We observed within group improvements in GI inflammation (p=0.01) and a trending improvement in colon pain (p=0.08) in individuals consuming B. lactis with PreforPro, but not in the group consuming only the probiotic. There was also a larger increase in Lactobacillus and short chain fatty acid-producing microbial taxa detected in stool of participants taking PreforPro with B. lactis compared to the probiotic alone. Overall, these results suggest the addition of PreforPro as a combination therapy may alter gut ecology to extend the GI benefits of consuming B. lactis or other probiotics.
Impact of the chemical description on direct numerical simulations and large eddy simulations of turbulent combustion in industrial aero-engines

A growing need for numerical simulations based on reliable chemistries has been observed in the last years in order to develop new technologies which could guarantee the reduction of the enviromental impact on air transport. The description of combustion requires the use of detailed kinetic mechanisms for most hydro-carbons. Their use in turbulent combustion simulation is still prohibitive because of their high computational cost. Reduced chemistries and tabulation methods have been proposed to over-come this problem. Since all these reductions have been developed for laminar conﬁgurations, this thesis proposes to evaluate their performances in simulations of turbulent conﬁgurations such as a DNS of a premixed Bunsen methane/air ﬂame and a LES of an experimental PREC-CINSTA burner. The mechanisms are analysed in terms of ﬂame structure, global burning parameters, ﬂame length, prediction of major species concentrations and pollutant emissions. An a priori methodology based on one-dimensional unstrained and strained laminar ﬂames to evaluate the mechanism capability to predict three-dimensional turbulent ﬂame features is therefore proposed. On the one hand when building a new reduced scheme, its requirements should be ﬁxed compromising the computational cost, the robustness of the chemical description and the desired quality of results. On the other hand, the quality of DNS or LES results in three-dimensional conﬁgurations could be anticipated testing the reduced mechanism on laminar one-dimensional premixed unstrained and strained ﬂames.
Conformance Quality of the Dual-Channel Tourism Supply Chain under Tourists’ Quality Preference

ABSTRACT The arising of unprofessional service in package tour makes conformance quality control increasingly important. This paper constructs a game model of dual-channel tourism supply chain composed of a traditional tour retail channel and an online channel under tourists’ quality preference. Focus on the condition that tour retailer provides extra service as differentiation strategy, the impacts of conformance quality on the decision-making of centralized and decentralized systems are analyzed with mathematical analysis, as well as the equilibrium conformance quality and the coordination strategy. This paper further compares the conformance quality and profits in centralized, decentralized, and coordinated systems and provides a sensitivity analysis of tourists’ quality preferences with numerical analysis. The results indicate that the conformance quality produces different impacts on the two channels. Decentralized structure is the dominant strategy, while centralized structure is more conductive to conformance quality control. The two-part tariff strategy is proposed and demonstrated to be effective in improving conformance quality. Tourists’ quality preferences are conductive to increasing the equilibrium conformance quality under certain conditions. This study provides guidance to the sustainable development of dual-channel tourism supply chain.
A prospective observational study to evaluate the maternal and neonatal outcome of forceps delivery in a tertiary care government hospital

Introduction: The art of forceps delivery is a practice that dates back several centuries. Modern obstetrics practice has witnessed an increase in the caesarean section rates. The goal of forceps delivery is to mimic spontaneous vaginal birth, thereby expediting delivery with a minimum of maternal or neonatal morbidity. Its safe and proper use can reduce the rising cesarean section rates. This study is aimed to see the outcome of its use in a teaching hospital over a 1 year period. Materials and Methods: In this Prospective observational study, 158 cases of forceps delivery were studied for maternal outcome such as injuries, failue of forceps, postpartum hemorrhage, need of blood transfusion and neonatal outcome such as birth weight, Apgar scores, neonatal intensive care unit admissions or any fetal morbidity or mortality. Results: Out of the 158 patients, 76.58% of patients requiring forceps application were primigravida. The most common indication was fetal distress (55.69%) followed by maternal exhaustion. The most common maternal complication was maternal injuries such as vaginal lacerations. (9.49%), 3 cases of failure of forceps delivery (1.89%), vulvovaginal hematoma in 2 cases, 6 cases of complete perineal tears with 6 cases of Postpartum hemorrhage requiring blood transfusion. There was 1 case of uterine rupture which was in a previous lower segment caesarean section case. Out of total of 15 babies (9.49%) who had poor Apgar scores 14 recovered after resuscitation with 1 case of stillbirth where fetal distress was indication of forceps delivery. Conclusion: Forceps is a considerable and safe option for the obstetrician to reduce the caesarean section rates; however, extreme caution, proper expertise and judicial use of this instrument is required to prevent undue risk to mother and fetus.
Shared Space: How North American Olympic Broadcasters Framed Gender on Instagram

The Olympic Games offer scholars the opportunity to better understand how broadcasters visually frame male and female athletes to their large audiences. Traditionally, scholars have focused their efforts on the televised Olympic broadcasts and photojournalism coverage in newspaper and magazines. Scholarship has historically found that female athletes were underrepresented in event coverage and framed along gender stereotypes; however, in more recent Olympic Games, research has shown the news media has provided more equitable coverage between the genders. Yet digital and social media platforms (SMPs) play a significantly larger role in how Olympic broadcasters share content and engage with audiences. Utilizing media framing theory, this study examines how gender is framed on the Olympic Instagram accounts of the two official North American rights holders: the National Broadcasting Corporation (NBC) and the Canadian Broadcasting Corporation (CBC). Researchers collected a cross-sectional sample from the 2016 Summer Games in Rio de Janeiro, Brazil, and the 2018 Winter Games in Pyeongchang, South Korea. Results indicate that NBC and CBC were generally equitable in SMP coverage of men’s and women’s athletic achievements.
Making a difference in the community: local civic engagement efficacy among immigrants and refugees in King County, Washington

ABSTRACT Issues of immigration and citizenship are at the forefront of policy and public opinion in the United States. This study explores immigrant and refugee perceptions of their ability to make a difference in their community by leveraging an extensive survey conducted in King County, Washington. Findings show that immigrants and refugees who were more interested in the 2016 presidential election, more likely to vote in the 2016 presidential election, and could easily access election information in their preferred language were significantly more likely to believe they could make a difference in their community. This study adds to the literature by showing empirically the ways in which sociocultural factors shape civic efficacy among immigrants and refugees, while building on previous research on political efficacy and participation based on psychological mechanisms to show the broader role of sociocultural environment on civic efficacy.
Classification of white varietal wines using chemical analysis and sensorial evaluations

The ways of application of multivariate data analysis and ANOVA to classification of white varietal wines are here demonstrated. Wine classification was performed using the following classification criteria: winevariety, year of production, wine producer, and wine quality, as found by sensorial testing (bouquet, colour, and taste). Subjective wine evaluation, made by wine experts, is combined with commonly used chemical and physico-chemical properties, measured in analytical laboratory. Importance of the measured variables was determined by principal component analysis and confirmed by analysis of variance. Linear discriminant analysis enabled not only a very successful wine classification but also prediction of the wine category for unknown samples. The wine categories were set up either by three wine varieties, or two vintages, wine producers; two or three wine categories established by wine quality reflected either total points obtained in sensorial evaluation or the points obtained for a particular quality descriptor like colour, taste and bouquet.
Virus Shook the Streaming Star: Estimating the COVID-19 Impact on Music Consumption

Many have speculated that the recent outbreak of COVID-19 has led to changes in how people consume media and a surge in the use of online streaming services. However, this assumption has not been closely examined for music streaming services, the consumption patterns of which can be different from video streaming services. To provide insights into this question, we analyze Spotify’s streaming data for weekly top 200 songs for two years in 60 countries, along with COVID-19 case and lockdown policy statistics, and detailed daily mobility information from Google. Empirical evidence shows that the COVID-19 outbreak significantly reduced music streaming consumption in many countries. The data over time and by country suggests that the decline in streaming demand was primarily linked to the number of COVID-19 cases. We also find strong evidence that countries with larger decreases in mobility and transit time present more notable reduction after the pandemic. Further, we reveal that music consumption via online video channels, less complementary to other activities like commuting, exhibits opposite patterns. We provide suggestive evidence that our findings were unlikely to be driven by unobservable Spotify-specific factors or by a shift in demand from top-selling songs to niche music. Also discussed are other demand- and supply-side effects as well as managerial implications.
In-laws or outlaws? Associations between in-law family members’ and individuals’ convictions

The association between individuals’ criminal behaviour and the criminal behaviour of their in-law family members is central to the current study. The criminality of extended family members may pose a risk of (persistence in) criminal behaviour. Data are used from the fourth generation of the Dutch Transfive Study, which contains demographical data as well as and conviction data on family members from consecutive generations of families. Results show a significant association between convictions of individuals and their in-law family members, over and above the effect of having a convicted partner. The strength of the association depends on the severity of the offense as well as on gender. Similarity in convictions before marriage as well as indications of continued similarity after marriage has been found.
