失意,是帖清醒剂

人在旅途,能够"一路绿灯、一帆风顺"的极少.从记事起,人就在得意与失意之间生活.得意时,如浸泡在蜜水之中,喜悦万分;失意时,如含黄连之汁,苦不堪言.对绝大多数人来说,在人生的长河中,曲折、挫折、磨难往往多于坦途、顺利、成功.

失意的鸡皮疙瘩

为什么冷的时候会起鸡皮疙瘩，害怕的时候也会起鸡皮疙瘩？

Automatic road extraction framework based on codec network

Road extraction based on deep learning is one of hot spots of semantic segmentation in the past decade.In this work,we proposed a framework based on codec network for automatic road extraction from remote sensing images.Firstly,a pre-trained ResNet34 was migrated to U-Net and its encoding structure was replaced to deepen the number of network layers,which reduces the error rate of road segmentation and the loss of details.Secondly,dilated convolution was used to connect the encoder and the decoder of network to expand the receptive field and retain more low-dimensional information of the image.Afterwards,the channel attention mechanism was used to select the information of the feature image obtained by up-sampling of the encoder,the weights of target features were optimized to enhance the features of target region and suppress the features of background and noise regions,and thus the feature extraction effect of the remote sensing image with complex background was optimized.Finally,an adaptive sigmoid loss function was proposed,which optimizes the imbalance between the road and the background,and makes the model reach the optimal solution.Experimental results show that compared with several semantic segmentation networks,the proposed method can greatly reduce the error rate of road segmentation and effectively improve the accuracy of road extraction from remote sensing images.

A Cognitive Study on Politeness Intention Processing and Its Association with Pragmatic Failure in Cross-Cultural Communication

Although a large number of studies have focused on various aspects of politeness,very little is known about how politeness intention is activated cognitively during verbal communication.The present study aims to explore the cognitive mechanism of politeness intention processing,and how it is related to pragmatic failure during cross-cultural communication.Using 30 Chinese EFL university students who were instructed to finish a probe word judgment task with 96 virtual scenarios,the results indicate that within both mono-and cross-cultural contexts,the response time in the experimental scenarios was significantly slower than that of the filler scenarios.This suggests that politeness intention was activated while understanding the surface meaning of the conversation;however,the EFL learners could not completely avoid the negative transfer of their native politeness conventions when they were comprehending the conversational intention of the target language.Furthermore,no significant differences in response time were found between the groups with high and low English pragmatic competence,illustrating that transferring the pragmatic rules and principles into cross-cultural communication skills was more cognitively demanding.Overall,this study adds to the literature on politeness research and provides some implications for foreign language pragmatic instructions.

Debris Flows Risk Analysis and Direct Loss Estimation:the Case Study of Valtellina di Tirano,Italy

andslide risk analysis is one of the primary studies providing essential instructions to the subsequent risk management process. The quantification of tangible and intangible potential losses is a critical step because it provides essential data upon which judgments can be made and policy can be formulated. This study aims at quantifying direct economic losses from debris flows at a medium scale in the study area in Italian Central Alps. Available hazard maps were the main inputs of this study. These maps were overlaid with information concerning elements at risk and their economic value. Then, a combination of both market and construction values was used to obtain estimates of future economic losses. As a result, two direct economic risk maps were prepared together with risk curves, useful to summarize expected monetary damage against the respective hazard probability. Afterwards, a qualitative risk map derived using a risk matrix officially provided by the set of laws issued by the regional government, was prepared. The results delimit areas of high economic as well as strategic importance which might be affected by debris flows in the future. Aside from limitations and inaccuracies inherently included in risk analysis process, identification of high risk areas allows local authorities to focus their attention on the “hot-spots”, where important consequences may arise and local （large） scale analysis needs to be performed with more precise cost-effectiveness ratio. The risk maps can be also used by the local authorities to increase population’s adaptive capacity in the disaster prevention process.

The Natural Forest Protection Program in China： A Contingent Valuation Study in Heilongjiang Province

In 1998, the Chinese Government implemented the NFPP （Natural Forest Protection Program）, which included logging restrictions, protected areas, replanting, and a range of other policies aimed at safeguarding the state of the country＇s forests and reducing the risk of erosion and flooding. A second phase of this program is currently being discussed. In this paper, contingent valuation is used to estimate the WTP （willingness to pay） for maintaining the program among the inhabitants in Heilongjiang Province in northern China. The results show that, even with fairly conservative assumptions, the aggregated WTP for maintaining the program for another five years is some 3.24 billion yuan per year. This can be compared with the current cost of the Program in the province, which is some 1.57 billion yuan per year.

Can mean platelet volume play a role in evaluating the severity of acute pancreatitis?

AIM To investigate serum mean platelet volume(MPV) levels in acute pancreatitis(AP) patients and assess whether MPV effectively predicts the disease severity of AP.METHODS We included 117 consecutive patients with AP as the AP group and 34 consecutive patients with colorectal polyps(before endoscopic treatment) as the control group. Complete blood counts, liver function, platelet indices(MPV), coagulation parameters, lactate dehydrogenase(LDH) and C-reactive protein(CRP) were measured on days 1, 2, 3 and 7 after admission. Receiver operating characteristic curves were used to compare the sensitivity and specificity of MPV, white blood cell(WBC), LDH and CRP in predicting AP severity. The Modified Glasgow Prognostic Score(m GPS) and the 2012 revised Atlanta criteria were used to evaluate disease severity in AP.RESULTS MPV levels were significantly lower in the AP group than in the control group on day 1(P = 0.000), day 2(P = 0.029) and day 3(P = 0.001) after admission.In addition, MPV values were lower on day 1 after admission than on day 2(P = 0.012), day 3(P = 0.000) and day 7(P = 0.002) in all AP patients. Based on the m GPS, 78 patients(66.7%) were diagnosed with mild and 39 patients(33.3%) with severe AP. There was no significant difference in mean MPV levels between patients diagnosed with mild and severe AP based on the m GPS(P = 0.424). According to the 2012 revised Atlanta criteria, there were 98 patients(83.8%) without persistent organ failure(OF) [non-severe acute pancreatitis(non-SAP) group] and 19 patients(16.2%) with persistent OF(SAP group). MPV levels were significantly lower in the SAP group than in the non-SAP group on day 1 after admission(P = 0.002). On day 1 after admission using a cut-off value of 6.65 f L, the overall accuracy of MPV for predicting SAP according to the 2012 revised Atlanta criteria(AUC = 0.716) had a sensitivity of 91.8% and a specificity of 47.4% and was superior to the accuracy of the traditional markers WBC(AUC = 0.700) and LDH(AUC = 0.697).CONCLUSION MPV can be used at no additional cost as a useful, noninvasive biomarker that distinguishes AP with persistent OF from AP without persistent OF on day 1 of hospital admission.

Marital and Co-parenting Relationships After Divorce： Continuity and Discontinuity

Divorced parents are challenged by the task of creating new role identities as co-parents while no longer living together and being married. The process of families＇ reorganization, following divorce, can be studied in terms of emotional adjustment, co-parenting and family alliance. The aims of this work are to analyze the process（es） of reorganization, in a sample of Italian divorced families （n =104）, with regards to the constructs of adjustment to divorce, co-parenting and family alliance and to explore their relationships. Multi-method procedure involves both self-report measure for the evaluation of representations＇ level and observational measure for the evaluation of interactive models. Preliminary results indicate functional and dysfunctional pathways between the families and show the association between representation level and interactive practices. Results are discussed.

Iconography of National Mourning in Polish Press

By the law, the highest-ranking state officials announce national mouming in response to death of prominent persons. The concept of mourning should be understood both as way of showing grief in public spaces and a period of time. In turn, the concept of iconography means a collection of illustrations, paintings, prints, drawings relating to a person, place or topic. President of Poland, his wife and other 94 people died in the Smolensk plane crash on April 10, 2010, thus the images of plane crash and its outcome published in different segments of Polish press are the subject of the article. Research based on methods such as interpretation of composition and semiotics. I started my analysis with a few hypotheses： （1） The cultural background, especially religious, determines the mourning visual representation; （2） The result of certain style of visualization can be constructing of a political myth; （3） Different means can be used by mass media in adapting culture patterns process; （4） Different photographic genres can be used to illustrate the mourning; and （5） Press segments differ in way/style of mourning visualization.

A Damage Scenario for the 2012 Northern Italy Earthquakes and Estimation of the Economic Losses to Residential Buildings

In May 2012 a seismic sequence occurred in Northern Italy that was characterized by two main shocks with a magnitude range between 5.5 and 6. These shocks represent a good case study by which to quantify the monetary losses caused by a moderate earthquake in a densely populated and economically well-developed area.The loss estimation accounts for damage to residential buildings, and considers the full effect of all the seismic aftershock events that lasted for nearly a month. The building damage estimation is based on the European Macroseismic Scale(EMS-98) definitions, which depict the effects of an earthquake on built-up areas in terms of observed intensities. Input data sources are the residential building census provided by Istituto Nazionale di Statistica—the Italian National Institute of Statistics(ISTAT)—and the official market value of real estate assets, obtained from the Osservatorio del Mercato Immobiliare—the Real Estate Market Observatory(OMI). These data make it possible to quantify the economic losses due to earthquakes, an economic indicator updated yearly. The proposed multidisciplinary method takes advantage of seismic,engineering, and economic data sets, and is able to provide a reasonable after the event losses scenario. Data are not gathered for each single building and the intensity values are not a simple hazard indicator, but, notwithstanding its coarseness, this method ensures both robust and reproducible results. As the local property value is availablethroughout the Italian territory, the present loss assessment can be effortlessly repeated for any area, and may be quickly reproduced in case of future events, or used for predictive economic estimations.

Cognitive Dissonance and ＂The Will to Believe＂

That we shape our beliefs to align with our actions should be of interest within philosophy of religion and philosophy generally. Cognitive dissonance, a psychological state in which an individual＇s beliefs and actions do not conform with each other, presents just such a situation. The idea that cognitive dissonance, by strict evidentialist standards, compromises our epistemic integrity since cognitive dissonance causes us to hold beliefs for which we do not have evidence, recalls the exchange between William Clifford and William James in which they discuss evidentialism, the idea that we should hold no beliefs for which we do not have evidence. In this paper I draw upon extant published research concerning cognitive dissonance theory and religion. I also survey the Clifford-James debate, applying considerations from their exchange to cognitive dissonance and （religious） belief. I conclude by showing how cognitive dissonance can have ambiguous results as concerns the justification of beliefs and that philosophy could benefit from attending to factors impacting empirical aspects of belief formation such as cognitive dissonance.

Effect of hepatic function on the EC_(50) of midazolam and the BIS_(50) at the time of loss of consciousness

Objective： To explore the effect of hepatic function on loss of consciousness （LOC） and bispectral index （BIS） during sedation with midazolam （MDZ）. Methods： Forty-five patients were assigned to three groups according to their liver function. Thirty of these patients with diagnoses of cholelithiasis were scheduled laparoscopic cholecys- tectomy, including 15 patients with normal liver function （normal group）, and 15 patients with moderately abnormal liver function based on the results of ultrasonic diagnosis of a moderately fatty liver and elevated alanine transaminase levels of less than three times normal （moderate group）. The other 15 patients with end-stage liver disease （severe group） underwent liver transplantation. Each patient was administered MDZ by way of target-controlled infusion to increase the concentration gradually. At the time of LOC, the BIS was recorded and a blood sample was withdrawn for measurement of the concentration of MDZ. The concentration of MDZ （EC50） and the BIS value （BIS50） at which 50% of patients lose consciousness were calculated using logistic regression. Results： At the time of LOC, the EC50 of MDZ and the BIS50 were similar in the normal and moderate groups （P〉0.05）. LOC occurred at a lower EC50 of MDZ and at a higher BIS50 in the severe group, compared with the normal and moderate groups （P〈0.01）. Conclusions： Patients with end-stage liver disease were more sensitive to MDZ and this affected the prediction of their time of LOC following MDZ administration. There were no changes in response in patients with moderately abnormal hepatic function.
