卫人教女

卫人嫁其子(古代子兼指男和女)而教之曰:'必私积聚。为人妇而出(古代男方离弃妻子叫出妻),常也。其成居(白头到老),幸也。'其子因私积聚,其姑(婆婆)以为多私而出之。其子所以返者,倍其所以嫁,其父不自罪于教子非(错误)也,而自知其益富。今人臣之处官者,皆是类也。

中西古代寓言的比较

一、比较的前提 “寓言”这个名称,在我国有新者两个概念,弄清它们的不同,是我们进行中西古代寓言比较的前提。 “寓言”一词出自《庄子),本义是“托之他人之言”,就是作者把自己的话假托是别的某些人的话,用以取信于读者的手法。后来引伸为“有所寄托或比喻之言,”这种寓言中往往使用一些小故事,但又不尽然,没有故事的寓言还是很多的。如《庄子》,《史记》说它“大抵率寓言也。”意思是说《庄子》一书摹本上都是寓言,但其中的小故事毕竟有限。所以在我国古代凡“有所寄托或比喻”性质的作品,都可以看作寓言,并不单指某些小故事。这是它的老概念。

Comparison of Newly Synthetic Hexaploid Wheat with Its Donors on SSR Products

Microsatellites or SSRs as powerful genetic markers have widely been used in genetics and evolutionary biology in common wheat. Because of the high polymorphism, newly synthesized hexaploid wheat has been used in the construction of genetic segregation population for SSR markers, However, data on the evolution of microsatellites during the polyploidization event of hexaploid wheat are limited. In this study, 66 pairs of specific to A/B genome SSR patterns among newly synthesized hexaploid wheat, the donor tetraploid wheat and Aegilops tauschii were compared. The results indicated that most SSR markers were conserved during the polyploidization events of newly synthetic hexaploid wheat, from Triticum turgidum and Ae. tauschii. Over 70% A/B genome specific SSR markers could amplify the SSR sequences from the D genome ofAe. tauschii. Most amplified fragments from Ae, tauschii were detected in synthetic hexaploid at corresponding positions with the same sizes and patterns as in its parental Ae. tauschii. This suggested that these SSR markers, specific for A/B genome in common wheat, could amplify SSR products of D genome besides A/B genome in the newly synthesized hexaploid wheat, that is, these SSR primers specific for A/B genome in common wheat were nonspecific for the A/B genome in the synthetic hexaploid wheat. In addition, one amplified Ae. tauschii product was not detected in the newly synthetic hexaploid wheat. An extra-amplified product was found in the newly synthetic hexaploid wheat. These results suggested that caution should be taken when using SSR marker to genotype newly synthetic hexaploid wheat.

Objectives:Effective and efficient communication is a core element in healthcare systems,especially between healthcare providers and patients.This study aimed to identify communication barriers be-tween nurses and patients in primary healthcare centers in Bahrain.Methods:This is a cross-sectional study conducted across primary healthcare centers in Bahrain.Four hundred and two patients were recruited using convenience sampling.A self-administered question-naire comprising 29 items on communication barriers was used.Results:A total of 402 patients consented to participate.The majority of participants reported the following statements had large effects on communication:“shortage in the number of nurses compared to the large number of patients”(254/401,63.3%),“lack of desire of nurse to communicate with patients”(246/402,61.2%),and“negative attitude of the nurse toward the patient”(238/401,59.4%).Further,“difference in language between nurses and patients,”“lack of self-confidence by nurses,”and“nurses overwhelmed by work”were ranked as top three statements with a significant influence on commu-nication between nurses and patients.Conclusions:Communication between healthcare providers and patients is pivotal for an optimal healthcare service.Based on the findings of this study and the literature,we recommend formal training of health care workers in improving communication skills and including this not only in medical cur-riculum but also in the form of continuing medical education(CMEs)1.

Impacts of land use and climate change on regional net primary productivity

Combined with recent historical climate data and two periods of land use datasets from remote sensing data, we test the net primary productivity (NPP) data sets in North Chinamodelled by the satellite data-driven Global Production Efficiency Model (GLO-PEM) for detecting thewidespread spatial and temporal characteristics of the impacts of climate and land use change onthe regional NPP. Our results show that over the past 20 years, the mean annual temperature in thestudy region has remarkably increased by more than 0.064 ℃, but over the same period, there hasbeen a 1.49 mm decrease in annual precipitation and decrease in NPP by an annual rate of 6.9 TgC.The NPP changes in the study region were greatly affected by the average temperature andprecipitation by ten-day periods as well as the seasonal temperature and precipitation in the studyregion. The correlation between seasonal NPP and seasonal precipitation and temperature is highlyconsistent with land cover spatially, and the correlation coefficient changes with the changes ofvegetation types. The analysis reveals that the related areas in land use change only take up 5.45%of the whole studied region, so the climate changes dominate the impacts on the NPP in the wholestudy region (90% of the total). However, land use plays an absolute dominative role in areas withland cover changes, accounting for 97% of the total. From 1981 to 2000, the NPP in the whole studyregion remarkably reduced due to obvious precipitation decrease and temperature rise. Between twoperiods of land use (about 10 years), the changes in climate are predicted to promote a decrease inNPP by 78 ( + -0.6) TgC, and integrated impacts of climate changes and land use to promote adecrease in NPP by 87(+-0.8) TgC.

Analysis and assessment of land desertification in Xinjiang based on RS and GIS

The land desertification in Xinjiang was monitored and analyzed based on RS and GIS techniques. Satellite data interpretation was adopted to obtain the general situation of Xinjiang’s land desertification in assistance with the sampling method and on-the-spot investigations. Related monitoring and investigations showed that Xinjiang was facing with severe wide range land desertification, and its desertified area made up 77.08% of the total monitoring area. As for land types, the desertified farmland accounted for 1.92% of the total monitoring area, desertified woodland 4%, desertified grassland 45%, and unused land 49%. Accordingly, as for desertification degrees, non-desertified land occupied 22.92%, weak desertified land 5.69%, medium-degree desertified land 16.58%, severe desertified land 33.19% and super severe desertified land 21.61%. Finally, as for inducing factors, wind-eroded desertification made up 58.23%, water-eroded desertification 8.69%, salinization desertification 6.52% and frozen-melt eroded desertification 3.64%. Xinjiang’s land desertification tended to get worse and the harnessing mission remained hard.

With the rapid development of space technology,earth observation tech nology and sky observatory technolo-gy,they have played a more and more im portant part in monitoring and predi cting of earthquakes and volcanoes i n the terres-trial land.In recent years,the rela ted agencies have done the experimen ts and researches on monitoring and p redicting of earthquakes and volcanoes in the forewarning period by means of many appr oaches,such as satellite thermal in frared re-mote sensing(TIRS),Global Positioning System(GPS),differential interferometric syn thesis aperture radar(D-INSAR),astronomical time-latitude residual anomaly,and Geographic Information Systems (GIS),etc.A quite large number of re-search foundation has been built in t he fundamental theories and applica tion methods.The experiments and re searches have shown that these technology is e fficient methods for high frequency crust movement.If the existed separate scientific forces and results are possibly asse mbled together to form a more complete integration monitoring system wit h the combina-tion of space,sky observation,grou nd,deep geology and macro anomaly,i t will come into a new stage of monitoring and predicting of earthquakes and volca nic eruptions.

Approximate Approaches to Geometric Corrections of High Resolution Satellite Imagery

The exploitation of different non-rigorous mathematical models as opposed to the satellite rigorous models is discussed for geometric corrections and topographic/thematic maps pro duction of high-resolution satellite imagery (HRSI). Furthermore, this paper fo cuses on the effects of the number of GCPs and the terrain elevation difference within the area covered by the images on the obtained ground points accuracy. Fr om the research, it is obviously found that non-rigorous orientation and triang ulation models can be used successfully in most cases for 2D rectification and 3 D ground points determination without a camera model or the satellite ephemeris data. In addition, the accuracy up to the sub-pixel level in plane and about on e pixel in elevation can be achieved with a modest number of GCPs.

Self-endangering:A qualitative study on psychological mechanisms underlying nurses’burnout in long-term care

Objectives To develop a more specific understanding of psychological mechanisms in the development of burnout in long-term care as a basis for potential new intervention strategies aiming at improving nurses’mental health.Methods Two qualitative studies with thematic analysis were conducted.In Study 1,we conducted eight group interviews with 110 nurses from May–July 2019 in the context of workshops at eight nursing homes in Germany.In Study 2,we supplemented these with semi-structured interviews with 14 executives at German nursing homes in December 2019.Results The thematic analysis in Study 1 identified three main themes:causes of challenges,employees’opportunities for change,and organisational opportunities for change.Thematic analysis in Study 2 identified three main themes:job motives,reasons for filling in for others,and employee self-care.Further,our results show that the need to stand in for colleagues,in particular,is one of the greatest challenges for geriatric caregivers.In dealing with these challenges we found that self-endangering behaviour—a diminished ability to say no when asked to fill in or to do work overtime—was an important antecedent of nurses’burnout.Further,high levels of altruistic motivation and identification with the team or organisation were associated with self-endangering behaviour in the presence of adverse working conditions.Low levels of self-worth are a further risk factor for self-endangering.Conclusions Our findings are at odds with some core tenets of classic models of job demands and burnout that construe motivation and identification as resources.Our results show the need of a holistic intervention program in nursing including individual coaching,team-based interventions and organisational development processes.Employees themselves should be sensitized to this issue and supported in the long term,and politicians should create structures that do not encourage this behaviour any further.

Surface circulation patterns observed by drifters in the Yellow Sea in summer of 2001,2002 and 2003

In summer of 2001, 2002 and 2003, ten, six and seventeen satellite-tracked surface drifters with drogues centered at 15 and 4 m were deployed, respectively, in the southern Yellow Sea (YS). 23 drifters of them transmitted useful data of at least 30 days. The wind-driven component of the drift was removed from the original drift velocity of drifters. The wind data used are from NCEP (National Center for Environmental Prediction), USA.Trajectories and drift velocities of the 23 drifters depicted the upper circulation structure in the southern YS.There exists an anti-cyclonic eddy with a mean speed and radius of 0.063 m/s and 50km in the central southern YS, whose center lingered within 35.3-36.0°N / 123.5-124.0°E. Showed by 6 drifters, a basin-scale elliptic cyclonic gyre with a mean speed of 0.114 m/s, long and short radius of 250 and 200 km surrounds the anti-cyclonic eddy. In the southwestern part of the southern YS has obvious frontal eddy activities within about100 km with a mean speed about 0.076 m/s. All the drifters passing Korean coast were staggering for more than10 days west of a protruding cape of central Korea. A small-scale cyclonic eddy centered at around 120.5°E/35.1°N with a mean speed of 0.048 m/s was observed in western part of the southern YS.

SOME KEY ISSUES ON THE APPLICATION OF SATELLITE REMOTE SENSING TO MINING AREAS

After that the filtering of Radarsat image is discussed. Different filtering methods are experimented and compared, and adaptive methods are more efficient than others. Finally the classification of satellite RS image is studied, and some new methods including classification by improved BPNN(Back Propagation Neural Network) and classification based on GIS and knowledge are proposed.

Local Spiral Curves Simulating Based on Hough Transformation and Center Auto-Locating of Developing Typhoon

In the developing phase of typhoon formation, the spiral belt partly emerges in satellite cloud images. This research starts from images and moves on to graphics and then to representation and recognition. Following this route, local spiral cloud belt is segmented from the raw images using image segmentation, the spiral information is extracted using mathematic morphology, and local spiral curves are detected using Hough transformation. The problem of center locating of developing typhoon has finally been solved through a search algorithm of spiral curve. For No. 99082008 cloud image, the result produced by the algorithm in this paper is at 122..3 degree west longitude, 117.5 degree north latitude. The real typhoon center location was at 122.4 degree west longitude, 18 degree north latitude.
