On the Analysis of Negation in English Teaching

The negation in English is very complicated.It cannot be separated from the other parts of the whole sentence.We have to take all the factors of the whole sentence into account to understand the negation in English.This paper probes into the classification and the construction of the negation.It aims at providing a detailed analysis of negation in English teaching.

Negation of the Object in Sesotho

This article examines constituent negation in Sesotho. It investigates negation of the object argument in clauses with non-copulative verbs. In the case of non-copulative verbs, transitive and di-transitive constructions will be considered. The article argues that Sesotho does not have a direct means of negating clausal constituents but employs clauses such as cleft sentences and clauses with AGRS [ho] as well as contrastive clauses to effect negation. It further examines negation in terms of Haegeman5s (1995) Neg-Criterion, the well-formedness condition that determines the distribution and interpretation of negative elements. It gives a brief overview of grammatical concepts regarding negation and the notion object argument in its focus and post verbal positions, and explains how constituent negation, [the object argument] is realized in Sesotho.

The Application of Negative and Positive Words and Phrases in Chinese Negation Expressions

Negation is a ubiquitous phenomenon in all languages.In Chinese,there are a good number of such negative expressions as“fēi(非)”,“bu(不)”,“méi(没)”,“mò(莫)”,“bié(别)”,“wèi(未)”,“wú(无)”,“wù(勿)”,“fiào(覅)”,“béng(甭)”,“fǒu(否)”,and“miǎn(免)”as well as phrases with one of them.This paper is intended to explore the application of negation in Chinese in two ways:(1)People express positive meanings with negative words or phrases;(2)People express negative meanings with positive words or phrases.The linguistic data employed in this paper come from real life,microblogs,variety shows,short videos,and some hǎobùexpressions from three of China’s four classic novels.

The Influence of the Interaction Between Negation and Politeness on the Negation Structure

Negation is a grammatical phenomenon and often explored and explained from the formal perspective. In this thesis,negation itself can constitute sort of force, which is closely linked to politeness in communication. It is the interaction between negation and politeness that determines the negation structure, that is, the meaning of negation is expressed in other structures such as interrogative sentences than the mere negation structure. Here it is argued that these interrogatives are functionally equivalent to the negation structures, resulting from the interaction between the grammatical force and the pragmatic principles.

On the Scope of Negation in English

This paper deals with the scope of two types of English negation： the modal negation and the non-modal negation. It points out the possibility of ambiguity by reflecting the negative scope through word order in some structures and discusses the special features of these structures.

A Corpus-based Study on the Use of Affixal Negation in Chinese EFL Learners' Writing

This paper reports a comparative study on the use of affixal negation in the writing of Chinese EFL learners based on data collected from a learner corpus,WECCL and a native-speaker corpus,LOCNESS.The findings revealed that the overall frequency of affixal negation used by Chinese students was nearly the same as that of native speakers.And the top three most frequently used negative affixes of the two groups were the same in terms of their rankings and proportion.However,when it comes to individual negative affixes,some were underused while others overused.The reasons behind were explored in the analysis of un-,dis-and in-,the top three most frequently used negative affixes by Chinese EFL learners and native speakers.Pedagogical implications and suggestions for future research were presented at the end of the paper.

Impact of propofol and sevoflurane anesthesia on cognition and emotion in gastric cancer patients undergoing radical resection

BACKGROUND Propofol and sevoflurane are commonly used anesthetic agents for maintenance anesthesia during radical resection of gastric cancer.However,there is a debate concerning their differential effects on cognitive function,anxiety,and depression in patients undergoing this procedure.AIM To compare the effects of propofol and sevoflurane anesthesia on postoperative cognitive function,anxiety,depression,and organ function in patients undergoing radical resection of gastric cancer.METHODS A total of 80 patients were involved in this research.The subjects were divided into two groups:Propofol group and sevoflurane group.The evaluation scale for cognitive function was the Loewenstein occupational therapy cognitive assessment(LOTCA),and anxiety and depression were assessed with the aid of the self-rating anxiety scale(SAS)and self-rating depression scale(SDS).Hemodynamic indicators,oxidative stress levels,and pulmonary function were also measured.RESULTS The LOTCA score at 1 d after surgery was significantly lower in the propofol group than in the sevoflurane group.Additionally,the SAS and SDS scores of the sevoflurane group were significantly lower than those of the propofol group.The sevoflurane group showed greater stability in heart rate as well as the mean arterial pressure compared to the propofol group.Moreover,the sevoflurane group displayed better pulmonary function and less lung injury than the propofol group.CONCLUSION Both propofol and sevoflurane could be utilized as maintenance anesthesia during radical resection of gastric cancer.Propofol anesthesia has a minimal effect on patients'pulmonary function,consequently enhancing their postoperative recovery.Sevoflurane anesthesia causes less impairment on patients'cognitive function and mitigates negative emotions,leading to an improved postoperative mental state.Therefore,the selection of anesthetic agents should be based on the individual patient's specific circumstances.

Plume-lithosphere interaction in the Comei Large Igneous Province: Evidence from two types of mafic dykes in Gyangze, south Tibet, China

Two suites of mafic dykes,T1193-A and T1194-A,outcrop in Gyangze area,southeast Tibet.They are in the area of Comei LIP and have indistinguishable field occurrences with two other dykes in Gyangze,T0902 dyke with 137.7±1.3 Ma zircon age and T0907 dyke with 142±1.4 Ma zircon age reported by Wang YY et al.(2016),indicating coeval formation time.Taking all the four diabase dykes into consideration,two different types,OIB-type and weak enriched-type,can be summarized.The“OIB-type”samples,including T1193-A and T0907 dykes,show OIB-like geochemical features and have initial Sr-Nd isotopic values similar with most mafic products in Comei Large Igneous Provinces(LIP),suggesting that they represent melts directly generated from the Kerguelen mantle plume.The“weak enriched-type”samples,including T1194-A and T0902 dykes,have REEs and trace element patterns showing withinplate affinity but have obvious Nb-Ta-Ti negative anomalies.They show uniform lowerεNd(t)values(−6‒−2)and higher 87Sr/86Sr(t)values(0.706‒0.709)independent of their MgO variation,indicating one enriched mantle source.Considering their closely spatial and temporal relationship with the widespread Comei LIP magmatic products in Tethyan Himalaya,these“weak enriched-type”samples are consistent with mixing of melts from mantle plume and the above ancient Tethyan Himalaya subcontinental lithospheric mantle(SCLM)in different proportions.These weak enriched mafic rocks in Comei LIP form one special rock group and most likely suggest large scale hot mantle plume-continental lithosphere interaction.This process may lead to strong modification of the Tethyan Himalaya lithosphere in the Early Cretaceous.

The characteristics of negative corona discharge and radio interference at different altitudes based on coaxial wire-cylinder gap

The corona discharge from transmission lines in high-altitude areas is more severe than at lower altitudes. The radio interference caused thereby is a key factor to be considered when designing transmission lines. To study the influence of altitude on negative corona characteristics, an experimental platform comprising a movable small corona cage was established: experiments were conducted at four altitudes in the range of 1120-4320 m, and data on the corona current pulse and radio interference level of 0.8-mm diameter fine copper wire under different negative voltages were collected. The experimental results show that the average amplitude, repetition frequency and average current of the corona current pulse increase with increasing altitude. The dispersion of pulse amplitude increases with increase in altitude, while the randomness of the pulse interval decreases continuously. Taking the average current as an intermediate variable,the relationship between radio interference level and altitude is obtained. The result of this research has some significance for understanding the corona discharge characteristics of ultra-highvoltage lines.

The Negative Thermal Expansion Property of NdMnO_(3) Based on Pores Effect and Phase Transition

A novel negative thermal expansion(NTE) material NdMnO_(3) was synthesized by solid-state method at 1 523 K. The crystal structure, phase transition, pores effect and negative expansion properties of NdMnO_(3) were investigated by variable temperature X-ray diffraction(XRD), scanning electron microscope(SEM) and variable temperature Raman spectra. The compound exhibits NTE properties in the orderly O' phase crystal structure. When the temperature is from 293 to 759 K, the ceramic NdMnO_(3) shows negative thermal expansion of-4.7×10^(-6)/K. As temperature increases, the ceramic NdMnO_(3) presents NTE property range from 759 to 1 007 K. The average linear expansion coefficient is-18.88×10^(-6)/K. The physical mechanism of NTE is discussed and clarified through experiments.

Experimental results of a magnetic field modification to the radio frequency driver of a negative ion source

A magnetic field produced by a current flowing through the plasma grid(PG) is one of the solutions to reduce the collisional loss of negative ions in a negative ion source, which reduces the electron temperature in front of the PG. However, the magnetic field diffused into the driver has some influence on the plasma outflowing. In order to investigate the effect of changing this magnetic field on the outflowing of plasma from the driver, a circular ring(absorber) of high permeability iron has been introduced at the driver exit, which can reduce the magnetic field around it and improve plasma outflowing. With the application of the absorber, the electron density is increased by about 35%, and the extraction current measured from the extraction grid is increased from 1.02 A to 1.29 A. The results of the extraction experiment with cesium injection show that both the extraction grid(EG) current and H-current are increased when the absorber is introduced.

Objectives:To explore the relationship between college students’self-esteem(SE)and their social phobia(SP),as well as the mediating role of fear of negative evaluation(FNE)and the moderating effect of perfectionism.Methods:A convenience sampling survey was carried out for 1020 college students from Shandong Province of China,utilizing measures of college students’self-esteem,fear of negative evaluation,perfectionism,and social phobia.Data analysis was performed using the SPSS PROCESS macro.Results:(1)college students’self-esteem significantly and negatively predicts their social phobia(β=−0.31,t=−10.10,p<0.001);(2)fear of negative evaluation partially mediates the relation between self-esteem and social phobia among college students,with the mediating effect accounting for 48.97%of the total effect(TE);(3)the mediating role of fear of negative evaluation is moderated by perfectionism(β=0.18,t=7.75,p<0.001),where higher levels of perfectionism strengthen the mediating effect of fear of negative evaluation.Conclusions:Perfectionism moderates the mediating effect that fear of negative evaluation plays,establishing a moderated mediating model.

Review of Baduanjin and resistance exercise for the mental health of patients with hematologic malignancies

Patients with hematological tumors experience physical and psychological stress,and negative psychological states.Baduanjin,an emerging psychological rehabil-itation method combined with resistance exercise,has received widespread attention.This study reviews the current status of the application of Baduanjin combined with resistance exercise in improving the negative psychological state of patients with hematological tumors and discusses its problems and prospects.Through a literature review and comprehensive analysis,the application of Baduanjin and resistance exercise in the psychological rehabilitation of patients with hematological tumors was identified and evaluated.The results showed that Baduanjin with resistance exercise had a positive effect on improving negative psychological states of patients with hematological tumors,which can alleviate anxiety,depression,and other adverse emotions,and improve quality of life.However,there is a lack of unified and standardized exercise intervention programs for practical application,and patient participation and compliance must be improved.Baduanjin combined with resistance exercise can potentially improve the negative psychological status of patients with hematological tumors;however,it is still necessary to further standardize and improve the exercise program improving patient participation and compliance.Future studies should strengthen theoretical exploration and empirical research,providing more effective psychological rehabilitation strategies for patients with hematological tumors.

Effect of psychological nursing interventions on effectiveness and quality of life in schizophrenia patients receiving modified electroconvulsive therapy

BACKGROUND Schizophrenia is a common and severe mental disorder characterized by severe thought disturbances,hallucinations,delusions,and emotional instability.For some patients,conventional treatment methods may not effectively alleviate symptoms,necessitating the use of alternative therapeutic approaches.Modified electroconvulsive therapy(MECT)is an effective treatment modality for schizophrenia,inducing anti-depressive and antipsychotic effects through the stimulation of brain electrical activity.AIM To explore the impact of psychological nursing intervention(PNI)before and after MECT on the efficacy and quality of life of patients with schizophrenia.METHODS Eighty patients with schizophrenia who received MECT treatment from 2021 to 2023 were randomly divided into two groups:The intervention group(n=40)and the control group(n=40).The intervention group received PNI before and after MECT,while the control group received routine nursing care.The efficacy of MECT was evaluated by the Positive and Negative Syndrome Scale(PANSS)and the Clinical Global Impression Scale(CGI)before and after the treatment.The quality of life was assessed by the Short Form 36 Health Survey(SF-36)after the treatment.RESUITS The intervention group had significantly lower scores of PANSS and CGI than the control group after the treatment(P<0.05).The intervention group also had significantly higher scores of SF-36 than the control group in all domains except physical functioning(P<0.05).CONCLUSION PNI before and after MECT can improve the efficacy and quality of life of patients with schizophrenia.It is suggested that nurses should provide individualized and comprehensive psychological care for patients undergoing MECT to enhance their recovery and well-being.

Effectiveness of negative pressure wound therapy in complex surgical treatment of necrotizing fasciitis of the upper limb

BACKGROUND Necrotizing fasciitis(NF)of the upper extremities is a severe surgical pathology,and the incidence of this disease has been steadily increasing in recent decades.Surgical treatment is accompanied by the formation of extensive wounds,which can be treated with significant difficulties.In recent years,negative pressure wound therapy(NPWT)has proven to be highly effective.It is also promising for the treatment of NF.AIM To explore the effectiveness of NPWT in the treatment of NF of the upper extremities.METHODS The results of the treatment of 36 patients with NF of the upper extremities in two groups(NPWT group and control group;2022−2023)were retrospectively analyzed.In the NPWT group,the NPWT method(120 mmHg;constant mode)was used after surgical treatment.The number of vacuum-assisted dressings in patients ranged from 1 to 3,depending on the dynamics of the wound process.The duration of fixation of one bandage was up to 2−3 d.In the control group,conventional methods of local wound treatment were used.The following indicators were analyzed:The treatment delay,the prevalence of inflammation,the microbial landscape,the number of debridements,the duration of wound preparation for surgical closure,and the nature of skin plastic surgery.RESULTS Most patients experienced a significant treatment delay[4 d,interquartile range(IQR):2–7 d],which led to the spread of the pathological process to the forearm and shoulder.The most common pathogens were Staphylococcus aureus(14;38.9%)and Streptococcus pyogenes(22;61.1%).The average number of debridements per patient was 5(IQR:3–7),with no difference between groups.The average time to prepare wounds for surgical closure was 11±4 d in the NPWT group and 29±10 d(P=0.00001)in the control group.In the NPWT group,the wounds were more often closed with local tissues(15;83.3%),and in the control group,split-thickness skin grafts were more often used(4;50%).CONCLUSION The predominant isolation of Staphylococcus aureus and/or Streptococcus pyogenes from the lesions allowed us to classify these patients as NF type II.Multiple debridement procedures have become a feature of this disease treatment.The use of NPWT has significantly reduced the time required to prepare wounds for surgical closure.Early closure of wounds allows for more frequent use of local tissue repair,which ensures better results.NPWT is a highly effective way to prepare wounds for early surgical closure in patients with upper extremity NF.

Linking Perceived Risk of Public Health Emergency to Psychological Distress among Chinese College Students: The Chain Mediation Role of Balanced Time Perspective and Negative Coping Styles

Background:With public health emergencies(PHE)worldwide increasing,the perceived risk of PHE has been one of the critical factors influencing college students’psychological distress.However,the mechanisms by which the perceived risk of PHE affects college students’psychological distress are not clear.The study’s purpose was to investigate the mediation roles of deviation from a balanced time perspective(DBTP)and negative coping styles between the perceived risk of PHE and psychological distress.Methods:A convenience sampling method was used to survey 1054 Chinese college students with self-reporting.Data was collected using the Public Risk Perception Scale(PRPS),the Zimbardo Time Perspective Inventory(ZTPI),the Simplified Coping Style Questionnaire(SCSQ),the PHE Anxiety Scale,and the Chinese version of the Patient Health Questionnaire(PHQ).The associations between the perceived risk of PHE,DBTP,negative coping styles,and psychological distress were clarified using the correlation analysis.Additionally,the mediating roles of DBTP and negative coping styles between the perceived risk of PHE and psychological distress were investigated using a structural equation model.Results:The findings revealed low to moderate correlations between the variables studied.Students’perceived risk of PHE was a positive predictor of their psychological distress(b=0.219,p<0.01).DBTP and negative coping styles played chain mediation roles between them with the effect being 0.009 and a 95%Boot CI of[0.003,0.023].This chain mediation model had an excellent fit index(χ^(2)/df=4.732,CFI=0.973,TLI=0.930,RMSEA=0.048,SRMR=0.047).Conclusion:These findings showed how the perceived risk of PHE affected college students’psychological distress.Specifically,these results suggested that improving students’mental ability to switch effectively among different time perspectives depending on task features and situational considerations and reducing their negative coping styles might be effective ways to promote their mental health.

CONVERGENCERATESIN THESTRONG LAWSOFASYMPTOTICALLY NEGATIVELY ASSOCIATEDRANDOM FIELDS

In this paper, a notion of negative side ρ \|mixing ( ρ\+- \|mixing) which can be regarded as asymptotic negative association is defined, and some Rosenthal type inequalities for ρ\+- \|mixing random fields are established. The complete convergence and almost sure summability on the convergence rates with respect to the strong law of large numbers are also discussed for ρ\+-\| mixing random fields. The results obtained extend those for negatively associated sequences and ρ\+*\| mixing random fields.
