The Dynamics and Future Scenarios of the Animal Husbandry System in Khutag-Undur from 2015 to 2050

Under the conditions of climate warming,grassland degradation,frequent sandstorms,and fast increases in livestock numbers,coordinating animal husbandry and ecological protection is an important issue facing Mongolia.Using Khutag-Undur as an example,this study explores the dynamic process,future scenarios,and optimization strategies of the animal husbandry system in a typical Soum of Mongolia from 2015 to 2050 under three future climate socioeconomic scenarios of CMIP 6:SSP1-RCP2.6,SSP2-RCP4.5,and SSP5-RCP8.5.First,the animal husbandry system was deconstructed into three subsystems:grassland primary production,livestock secondary production,and herder consumption.Based on the negative feedback mechanism of forage-livestock balance,a system dynamics model for the Khutag-Undur Soum animal husbandry system was developed.This model integrates spatial data such as land cover and NPP,as well as statistical data on livestock,herder income and expenditures,sample plot surveys,and herder questionnaires.The model was used to simulate the historical changes(2015-2022)in forage production and carrying capacity,livestock stock,and livestock output of Khutag-Undur,and then to forecast the future scenarios of those variables for 2022-2050.Second,the most suitable future scenario for the Soum was identified by comparing the three future scenarios using a pastural system sustainability evaluation method.Finally,based on three indicators of livestock numbers,a two-step livestock reduction strategy was proposed.The main conclusions are that the rapid growth of livestock numbers in Khutag-Undur places considerable pressure on the grassland,and the SSP1-RCP2.6 scenario is the most suitable future scenario for the Soum.However,even in this suitable scenario,grassland overloading remains evident.The continuous implementation of a livestock reduction strategy is recommended to maintain the sustainable development of animal husbandry and grassland conservation.

Water quality changing trends of the Miyun Reservoir

In order to simulate changes in the water quality of the Miyun Reservoir dueto continuous descent of surface water level, a 3-D ecological hydrodynamic model was developedthrough coupling the water quality analysis simulation program (WASP) with the environmental fluiddynamics code (EFDC). The model was then calibrated and verified. Four scenarios (S1, S21, S22 andS23) were simulated using the model. Results show that the water quality of the Miyun Reservoirunder conditions of low surface water level is apparently affected by different amounts of inflowand different total phosphorus (TP) loadings. The chlorophyll-a concentration might exceed 10 μg/Lin many areas of the Miyun Reservoir (This limitative value is seen as a critical value ofeutrophication) when large loadings of TP enter due to the amount of inflow increasing. Results ofscenario S23 indicate that control of TP loadings can decrease chlorophyll-a concentrationeffectively, and the water quality of the Miyun Reservoir will improve or retain its status quo.

From Suffering to Satisfaction in Method Acting

We analyze the success of Konstantin Stanislavski＇s method of emotion memory in Western acting schools. We propose a path that, counter-intuitively, connects the emotional distress related to this method with an attachment to it. A chain of psychological steps explains this dynamic： the delegation of power from the actor to the director, emotional suffering during the training, rise of feelings within the dyad, and eventually rise of satisfaction. Our argument draws especially on interdisciplinary research on athlete-coach relationships in sports psychology while also suggesting wider application to educational psychology and psychotherapy.

On the application of motivational strategies in public English class in college

With the development of society and economy, English gradually becomes a worldwide language. However, due to various kinds of reasons and restrictions, many problems still exist in present English language teaching in public English classes. This paper focuses on the application and effect of some useful motivational strategies in English classroom, such as making use of affective factors, developing good classroom atmosphere, and becoming an efficient manager. The researcher hopes that this contribution can offer some valuable guidelines to English teachers. Therefore, the existing problems can be solved gradually.

The pertinent meaning of the modal verbs in translation analysis

Modality as a major exponent of interpersonal relations has been extensively studied. It is mostly studied in a highly individual centered view that individual speakers and their relations to one another are central, and social relations are built up through the linguistic interactions of speakers. In most case, a modal verb expresses the speaker＇s or the author＇s attitude at the time of speaking. So, it is very necessary that we learn the meaning of the modal verbs in translation. This paper talked about the modality, the types of modality, modal commitment and finally the meaning of the modal verbs in translation.

Situational Sports Teaching Model and Its Application

It is to conduct the teaching exploration for the situational sports model＇s implementation in sports teaching. It is indicated that the implementation of the situational teaching is good to improve the students＇ initiative and interest for study; good for the students＇ participation; good to improve students＇ initiative, sports ability and sports level; good to promote students to have healthy physical and psychological development; good to optimize the teaching process and activate the class atmosphere; and also good to promote students＇ social development factor. It is an ideal teaching concept and teaching model.

Effect of Stimulation of Shenshu Point on the Aging Process of Genital System in Aged Female Rats and the Role of Monoamine Neurotransmitters

In this experiment, among some aged female rats aged over 18 months, and young female rats aged 3 months whose central noradrenergic nerve endings were injured by ventricular injection of 6-hydroxy-dopamine (6-OHDA), it was observed that catgut embedding at bilateral Shenshu (UB 23) points could obviously shorten sexual cycles, increase the frequency of sexual cycle, and slow down the aging process of the genital system in both the aged rats and in the rats with injured noradrenergic endings. After electroacupuncture (EA) at Shenshu (UB 23) points in the aged rats, the frequency of neuronal discharges in locus coeruleus (LC) was elevated and the activating rate of LC to neurons in the medial preoptic area (MPOA) of the hypothalamus was increased, while obvious effect on nucleus raphes magnus (NRM) and the effect of NRM on MPOA were not marked. It is suggested that stimulation of Shenshu (UB 23) point can strengthen the excitability of noradrenergic neurons, activate the ascending pathway of the brain stem - hypothalamus, raise the catecholamine (CA)/5-hydroxytryptamine (5-HT) ratio in the hypothalamus of the aged rats, so as to delay the aging process of the genital system.

Suppression dampens unpleasant emotion faster than reappraisal:Neural dynamics in a Chinese sample

The timing dynamics of regulating negative emotion with expressive suppression and cognitive reappraisal were investigated in a Chinese sample. Event-Related Potentials were recorded while subjects were required to view, suppress emotion expression to, or reappraise emotional pictures. The results showed a similar reduction in self-reported negative emotion during both strategies. Additionally, expressive suppression elicited larger amplitudes than reappraisal in central-frontal P3 component(340–480 ms). More importantly, the Late Positive Potential(LPP) amplitudes were decreased in each 200 ms of the 800–1600 ms time intervals during suppression vs. viewing conditions. In contrast, LPP amplitudes were similar for reappraisal and viewing conditions in all the time windows, except for the decreased amplitudes during reappraisal in the 1400–1600 ms. The LPP(but not P3) amplitudes were positively related to negative mood ratings, whereas the amplitudes of P3, rather than LPP, predict self-reported expressive suppression. These results suggest that expressive suppression decreases emotion responding more rapidly than reappraisal, at the cost of greater cognitive resource involvements in Chinese individuals.

SPREADING DYNAMICS OF A DISEASE-AWARENESS SIS MODEL ON COMPLEX NETWORKS

In this paper, to better understand the impact of awareness and the network structure on epidemic transmission, we divide the population into four subpopulations corresponding to different physical states and conscious states, and we first propose a modified disease- awareness model, then verify the global stability of the disease-free and endemic equilib- ria, and finally present numerical simulations to demonstrate the theoretical analysis. By examining the spreading influences of model parameters, we find that the outbreak scale can be effectively controlled through increasing the spread rate of awareness or reducing the rate of awareness loss. That is to say, all sorts of media publicity are meaningful. Meanwhile, we find that infection will be affected by consciousness through the control variable.
