BACKGROUND Alexithymia is defined as difficulties in identifying,expressing,and understanding emotions.An unapproving environment during childhood is defined as the child not receiving emotional approval from their parents,being punished,or having their emotions devalued.The formation of self-esteem is shaped by the influence of parental behavior during childhood.The commu-nication that the child establishes with their parents contributes to their increased self-esteem and sense of importance.The absence of this may play a role in developmental psychopathology.AIM To examine the mediating role of self-esteem in the relationship between a disapproving environment in childhood and alexithymia.METHODS The research in the relational screening model was conducted with 404 participants.Demographic Information Form,Disapproving Environment Scale in Childhood,Toronto Alexithymia Scale,and Rosenberg Self-Esteem Scale were used as data collection tools.Hayes’bootstrapping technique was used in the analysis of the data obtained from the research.RESULTS As a result of the analyses,parental disapproval positively predicted the level of alexithymia(rmother=0.51,rfather=0.52,P<0.05)and negatively predicted selfesteem(rmother=-0.75,rfather=-0.67,P<0.05).Additionally,self-esteem negatively predicted alexithymia(r=-0.58,P<0.05).It was observed that self-esteem had a partial mediating effect on the relationship between parental disapproval and alexithymia.Family types were analyzed separately as chaotic,approving,perfect,and typical.Of these,the chaotic family type positively predicted alexithymia(r=0.33,P<0.05)and negatively predicted self-esteem(r=-0.60,P<0.05).The approving family type negatively predicted alexithymia(r=-0.43,P<0.05)and positively predicted self-esteem(r=0.61,P<0.05).The perfect family type negatively predicted alexithymia(r=-0.27,P<0.05)and positively predicted self-esteem(r=-0.45,P<0.05).CONCLUSION The type of family in which the child grows up in and parental disapproval during childhood affected the child’s self-esteem and caused alexithymic personality traits. 展开更多

BACKGROUND Colorectal cancer(CRC)is a serious threat worldwide.Although early screening is suggested to be the most effective method to prevent and control CRC,the current situation of early screening for CRC is still not optimistic.In China,the incidence of CRC in the Yangtze River Delta region is increasing dramatically,but few studies have been conducted.Therefore,it is necessary to develop a simple and efficient early screening model for CRC.AIM To develop and validate an early-screening nomogram model to identify individuals at high risk of CRC.METHODS Data of 64448 participants obtained from Ningbo Hospital,China between 2014 and 2017 were retrospectively analyzed.The cohort comprised 64448 individuals,of which,530 were excluded due to missing or incorrect data.Of 63918,7607(11.9%)individuals were considered to be high risk for CRC,and 56311(88.1%)were not.The participants were randomly allocated to a training set(44743)or validation set(19175).The discriminatory ability,predictive accuracy,and clinical utility of the model were evaluated by constructing and analyzing receiver operating characteristic(ROC)curves and calibration curves and by decision curve analysis.Finally,the model was validated internally using a bootstrap resampling technique.RESULTS Seven variables,including demographic,lifestyle,and family history information,were examined.Multifactorial logistic regression analysis revealed that age[odds ratio(OR):1.03,95%confidence interval(CI):1.02-1.03,P<0.001],body mass index(BMI)(OR:1.07,95%CI:1.06-1.08,P<0.001),waist circumference(WC)(OR:1.03,95%CI:1.02-1.03 P<0.001),lifestyle(OR:0.45,95%CI:0.42-0.48,P<0.001),and family history(OR:4.28,95%CI:4.04-4.54,P<0.001)were the most significant predictors of high-risk CRC.Healthy lifestyle was a protective factor,whereas family history was the most significant risk factor.The area under the curve was 0.734(95%CI:0.723-0.745)for the final validation set ROC curve and 0.735(95%CI:0.728-0.742)for the training set ROC curve.The calibration curve demonstrated a high correlation between the CRC high-risk population predicted by the nomogram model and the actual CRC high-risk population.CONCLUSION The early-screening nomogram model for CRC prediction in high-risk populations developed in this study based on age,BMI,WC,lifestyle,and family history exhibited high accuracy. 展开更多

To quantify physicians'risk and time preferences and explore the association between the preferences and their willingness to detect and disclose secondary findings(SFs)derived from genome-scale sequencing.We designed a webbased survey incorporating a multiple price list(MPL)as the instrument for risk and time preference measurement.The estimation was under the expected utility theory(EUT)and rank dependent utility(RDU)frameworks,respectively.The isoelastic and power function utility models were applied.We received responses from 87 physicians,among whom 46 completed the questionnaire(a completion rate of 52.9%).We observed positive risk-aversion coefficients under EUT(0.33,95%CI 0.15-0.51)and RDU(0.51,95%CI 0.32-0.71),suggesting that physicians were generally risk-averse.Respondents were likely to underestimate probabilities of low to moderate levels,and slightly overestimate high-level probabilities.Physicians supporting the detection and disclosure of SFs had a larger risk-aversion coefficient and a smaller discounting parameter than the non-supporters,suggesting that they were more risk-averse and discounted future utility less.Assuming heterogeneous risk perception,we found respondents underestimated low/moderate risk and slightly overestimated high risk.This study indicates that physicians who are risk-averse and discount future utility slightly are willing to detect and return SFs.The findings contribute to the debate surrounding SF disclosure and generate implications for shared decision-making in clinical genome-scale sequencing. 展开更多

The aim of this work was to study the influence of the processing route on the microstructural constituents,hardness andtribological(wear and friction)behavior of Ti6Al4V biomedical alloy.In this sense,three different processing routes were studied:conventional casting,hot pressing and selective laser melting.A comprehensive metallurgical,mechanical and tribologicalcharacterization was performed by X-ray diffraction analysis,Vickers hardness tests and reciprocating ball-on-plate wear tests ofTi6Al4V/Al2O3sliding pairs.The results showed a great influence of the processing route on the microstructural constituents andconsequent differences on hardness and wear performance.The highest hardness and wear resistance were obtained for Ti6Al4Valloy produced by selective laser melting,due to a markedly different cooling rate that leads to significantly different microstructurewhen compared to hot pressing and casting.This study assesses and confirms that selective laser melting is potential to producecustomized Ti6Al4V implants with improved wear performance. 展开更多

Profile monitoring is used to check the stability of the quality of a product over time when the product quality is best represented by a function at each time point.However,most previous monitoring approaches have not considered that the argument values may vary from profile to profile,which is common in practice.A novel nonparametric control scheme based on profile error is proposed for monitoring nonlinear profiles with varied argument values.The proposed scheme uses the metrics of profile error as the statistics to construct the control charts.More details about the design of this nonparametric scheme are also discussed.The monitoring performance of the combined control scheme is compared with that of alternative nonparametric methods via simulation.Simulation studies show that the combined scheme is effective in detecting parameter error and is sensitive to small shifts in the process.In addition,due to the properties of the charting statistics,the out-of-control signal can provide diagnostic information for the users.Finally,the implementation steps of the proposed monitoring scheme are given and applied for monitoring the blade manufacturing process.With the application in blade manufacturing of aircraft engines,the proposed nonparametric control scheme is effective,interpretable,and easy to apply. 展开更多

The adequacy of language education largely depends on the favorable and unfavorable emotions that teachers and students experience throughout the education process.Simply said,emotional factors play a key role in improving the quality of language teaching and learning.Furthermore,these emotional factors also promote the well-being of language teachers and learners and place them in a suitable mental condition.In view of the favorable impact of emotional factors on the mental health of language teachers and learners,many educational scholars around the world have studied these factors,their background,and their pedagogical consequences.Nonetheless,the majority of previous studies have employed traditional research methods in assessing these variables and their influences on language teachers’and learners’mental health.Because of the complex and dynamic quality of emotional factors,traditional research approaches often fail to evaluate these factors and their dynamic,non-linear connections with teachers’and learners’mental health and well-being.Accordingly,some novel research approaches are required to measure the dynamicity and complexity of emotional factors in language education settings.To address this call,the current state-of-the-art conceptual article seeks to provide new insights for investigating emotional factors and their potential impact on language teachers’and learners’mental states.This study also intends to offer a comprehensive list of emerging methods that take into account the complex and dynamic nature of emotional variables.Finally,the study outlines the potential implications of this review for educational researchers. 展开更多

Turkey,containing three of the world’s biodiversity hotspots,is a hub for genetic biodiversity.However,the vegetation cover has drastically changed in recent decades as a result of substantial transformations in landuse practices.A map of the potential natural vegetation can be used to represent the biodiversity of a country,and therefore a reference to effectively develop conservation strategies.The multinomial logistic regression is used to simulate the probability of different biomes occurring in the country using elevation,climatological data and natural vegetation data.A correlation test was applied to the climatological data to determine which predictors influence vegetation the most.These were temperature,precipitation,relative humidity and cloudiness.The Ordinary Kriging method was employed to transform the data into the format for the multinomial logistic regression model.The model showed that temperature was the most influencing factor with respect to Turkey’s vegetation and distribution follows a similar distribution as the various macroclimates.Broadleaf forests are mostly found in the Black Sea region,which is also the wettest region of the country.The Marmara region is the only other region where there are broadleaf forests.Mixed forests and shrublands are mostly located in Central Anatolia due to the region’s low humidity which favours herbaceous flora.Coniferous forests were dominant in the Aegean and Mediterranean regions,attributed to high temperatures. 展开更多

Wild fodder plants are valuable because they provide an important livestock feed resource globally,especially for smallholder farmers,and have important roles in natural resource management.In-depth knowledge of wild forage plants can motivate local people for feed resource and habitat conservation of threatened herbivores such as Mithun(Bos frontalis).Mithun occur in small patches in the mountains of Dulongjiang,nearby villagers domesticated this animal but left animal to freely graze in the mountains.Many fodder plants occur in these mountains,however,little is known about their nutritional value.We conducted an ethnobotanical survey to document important wild fodder plants consumed by mithun in the Dulongjiang Township.The nutritional content of 21 highly mentioned wild fodder plants in an ethnobotanical survey was examined.Laboratory analysis showed that Fagopyrum dibotrys were the fodder species with the highest crude protein(CP)content(26.89%),followed by Polygonum molle(21.88%)and Hydrangea longipes(21.12%).Synthesis of relative feed value index and grey relational grade,P.molle,H.longipes and Tetrastigma obtectum were ranked the top three nutritional fodders.There was a significant difference between 21 species on their in vitro digestibility and the most highly digestible fodder species was Elatostema hookerianum.Linear model analysis on relationship between frequency of citation of 21 wild forage plants by local farmers and their nutrient composition showed that the frequency was significantly positively correlated with the nutritional value of the feed(R2?0.28,P<0.05).We concluded that these species have high nutritional values to improve mithun production in integrated crop-livestock systems.Fodder species or mixtures of species with useful nutritional characters could be cultivated to improve livestock productivity,habitat conservation including that of mithun and wild forage resource management. 展开更多

Monitoring and understanding the changes in mangrove ecosystems and their surroundings are required to determine how mangrove ecosystems are constantly changing while influenced by anthropogenic, and natural drivers. Cosistency in high spatial resolution (30 m) satellite and high performance computing facilities are limiting factors to the process, with storage and analysis requirements. With this, we present the Google Earth Engine (GEE) based approach for long term mapping of mangrove forests and their surroundings. In this study, we used a GEE based approach: 1) to create atmospheric contamination free data from 1987-2017 from different Landsat satellite imagery;and 2) evaluating the random forest classifier and post classification change detection method. The obtained overall accuracy for the years 1987 and 2017 was determined to be 0.87 and 0.96, followed by a Kappa coefficient 0.80 and 0.94. The change detection results revealed a significant decrease in the agricultural area, while there was an increase in mangrove forest, shrimp/fish farm, and bareland area. The results suggest that interconversion of land use and land cover is affecting the landscape dynamics within the study area. 展开更多

Powerful alluvial rivers in the northern Alborz mountain ranges erode river banks due to having high slopes.Most of these rivers flow in forest areas.In this research,the rate of the river bank erosion was examined using the exposed roots of the trees.For this purpose,8 reaches of Lavij Stream were investigated.To determine the first year of root exposure,two sets of macroscopic and microscopic indicators were utilized.Accordingly,the rate of the stream bank erosion was estimated.The results were analyzed by using statistical test,which showed insignificant differences between the two groups of indicators.Due to its more abundance(frequency)on the margins and easy detection of its root through the exposure(macroscopic and microscopic)indicators,Alnus glutinosa(black alder)species could be more easily and accurately analyzed as compared with any other tree species in the region.The mean erosion rate of the riverbank using the extruded roots was estimated to be 0.08 m/yr.The hydrological analyses of flood flows showed that 95%of Lavij Stream bank erosion was caused by the river bank full discharges with a return period of 1-3 years. 展开更多

During recent years, A new tendency has appeared among psychologists to pay more attention to the influence of family, cultural and social factors on the human personality and his internal needs. This tendency is in favor of more attention to religion for treatment of mental health, thought and mental disorders. The type of researches: this research is a correlation and post-event (causative) which has done with the purpose of studying the relationship between religious attitudes with attachment styles for the students. So a sample of 60 students of humanitarian sciences majors at the Islamic Azad University of Neyshabour randomly selected classical (according to the results of attachment style inventory, completed by 150 students). The religious attitudes of subjects were tested by Alport religious orientation inventory and their attachment style by Shiver and Hezen’s adult attachment test and were tested according to the results of descriptive and inferential statistics methods. The results of research indicated that for the subjects which have safe attachment style, their religious attitudes are internal. For the subjects which have unsafe attachment style (evidential, ambivalent), their religious attitudes are external. And also the subjects with ambivalent unsafe attachment style have internal religious attitudes in comparison with evidential unsafe attached persons. So, it can be said person’s attachment style is affected by their religious attitudes. As related to the attained results and comparing them with the results of past researches, it can be said that people with internal religious orientation and safe attached persons have confidence in others (especially to themselves) because of some personal characteristics. So, there is no reason for fear or for connivance of what they want and naturally will have an attitude which is needless to show pretension and hypocrisy. As a result, their religious attitude score in internal scale is more than external scale. 展开更多

This research aimed at determining the effectiveness of cognitive therapy based on mindfulness in marital fatigue and married women intimacy. The semi-experimental research design with witness group and evaluation for pretest-posttest was used. The study population consisted of married women, referred to health counseling center in the 1st district of Tehran during 2016 and lasted about 1 year. Using random sampling method, were selected 30 married women referred to health counseling center in the 1st district of Tehran, whom the main reason for their visit was declared incompatibility and marital conflict. And 15 of those who would like to participate in training mindfulness-based cognitive therapy, were in the experimental group and 15 others were in the witness group. For experimental group, were presented mindfulness-based interventions in 8 sessions every session in one and a half hours. In this study, to collect data was to use two questionnaires: measure marital intimacy and marital fatigue. After collecting the results, data were entered into the software Spss and assumptions were evaluated using analysis of covariance. The results showed that the average of experimental group compared with the control group after the intervention health was significantly different in variables like: physical fatigue, mental disability, emotional banality, and intimacy (p = 0.001). According to the findings above, it can be concluded that a mindfulness-based cognitive therapy training can reduce marital fatigue and as well as significantly effective in intimacy. 展开更多

Background: Canopy structure, defined by leaf area index (LAI), fractional vegetation cover (FCover) and fraction of absorbed photosynthetically active radiation (fAPAR), regulates a wide range of forest functions and ecosystem services. Spatially consistent field-measurements of canopy structure are however lacking, particularly for the tropics. Methods: Here, we introduce the Global LAI database: a global dataset of field-based canopy structure measurements spanning tropical forests in four continents (Africa, Asia, Australia and the Americas). We use these measurements to test for climate dependencies within and across continents, and to test for the potential of anthropogenic disturbance and forest protection to modulate those dependences. Results: Using data collected from 887 tropical forest plots, we show that maximum water deficit, defined across the most arid months of the year, is an important predictor of canopy structure, with all three canopy attributes declining significantly with increasing water deficit. Canopy attributes also increase with minimum temperature, and with the protection of forests according to both active (within protected areas) and passive measures (through topography). Once protection and continent effects are accounted for, other anthropogenic measures (e.g. human population) do not improve the model. Conclusions: We conclude that canopy structure in the tropics is primarily a consequence of forest adaptation to the maximum water deficits historically experienced within a given region. Climate change, and in particular changes in drought regimes may thus affect forest structure and function, but forest protection may offer some resilience against this effect. 展开更多
