Abstract
Ideological discourse has always challenged individuals as subjects and has always tried to use the polysemous character of language to predominate other discourses and subjects.This study attempts to answer the question of how the ideological discourse is able to carry out a semantic transformation on the discourse’s level and therefore on the conveyed message’s level, and that how the political authorities utilize linguistic structures and the means that language and the connotative modification of the language provide them to legitimize their supremacy in a schematic and schematized perspective.
To achieve this objective, this article’s authors have attempted to show the relationship between linguistic elements with power and domination by analyzing discourse of subjects in the Cannibale novel written by contemporary French writer Didier Daeninckx by relying on Pierre Zima’s sociological theories.Advocating the fight against denialism, racism, colonialism, corruption in political societies, he wrote Cannibale in 1998 in memory of the "human zoos" under the French Third Republic.It tells the story of indigenous Kanaks who were exhibited as animals at the 1931 Colonial Exhibition.Accordingly, this article examines how ideological discourse and semantic transformation are created through narratives and dialogues that occur throughout the book and lead to transforming ideological implications.Also, by describing and interpreting the nature of native Kanaks from the perspective of dominant ideological discourse, it is shown that dominant discourse uses the polysemous and multidimensional nature of language by holding the power to organize linguistic structures and defines a nature other than the original nature of the native Kanaks.

Abstract
Despite all the efforts of professors and students, learning the four language skills of French in academic institutions has always been accompqnied by challenges. One of these skills is written production, in which students make numerous mistakes. We believe that identifying and analyzing areas of error can be effective in improving their writing skills. In the present study, using an analytical-descriptive method, the written productions of a group of students on a B1 level topic were examined. The data collection tool is the DELF B1 evaluation grid with ten criteria for writing correction. The participants in this study show that 42 percent of students had very good and good averages, and 58 percent had average and weak scores. The target population of this study performed acceptably in only three skills-coherence and logical structure, the ability to present events, and adherence to the topic-out of the ten criteria in the evaluation grid. However, they have not yet achieved the necessary skills in the other seven criteria. The areas of errors revealed in this research could serve as topics for further studies to extract and analyze errors in each domain.

Abstract
Damage of both building and non-building structures (including the space structures) against earthquake is of great importance for civil engineers, because collapse of such large structures may have significant casualties and economic losses. Space structures are classified as large-scale structures and can cover a large space without columns. Seismic behavior of these structures is different from building structures. There are different types of space structures considering the geometrical aspects, which are effective in the damages causing economic and life losses. A space structure has three-dimensional behavior, and their higher-mode effects are remarkable. On the other hand, the weight of these structures is relatively low that may cause an unrealistic reduction in the calculation of seismic force in a static analysis. Therefore, the static analysis cannot capture their structural response effectively. Traditionally, the dynamic analysis is utilized for seismic design of space structures due to their complex structural behavior. Thus, in this paper, seismic design of two single-layer domes is performed using two dynamic analyses: time history analysis and response spectrum analysis. Although there are some studies on seismic design of domes, further investigations are required due to the structural diversity of different domes and the difference in their seismic behavior. Here, the ribbed and Schwedler domes under gravity and seismic loads are analyzed dynamically. The parameters of the design response spectral acceleration are based on ASCE7-16, and the site class (based on the soil type) is selected as “D”. Both horizontal and vertical components of seismic excitations are utilized in the dynamic analyses, because all these components are effective in design of a dome structure. The damping ratio is assumed to be 2% in the dynamic analyses based on the relevant literature. In the response spectrum analysis, the vertical seismic load is expressed in terms of dead loads in the response spectrum analysis. In the time history analysis, seven ground motion records are selected based on the seismic zone. These ground motion records are scaled using both amplitude scaling and spectral matching approaches. The vertical components are scaled to the specific vertical design spectrum obtained from ASCE7-16. In this study, seismic design of the ribbed and Schwedler domes with a span of 36 meters and a height of 6 meters are carried out with some limitations on the member stress ratios and top nodal displacements. The structural designs based on the time history analysis and the response spectrum analysis are compared. The same cross-sectional areas are used in designs of the dome structures to compare the effects of these dynamic analysis methods better. In general, the top node displacement and stress ratios of the dome obtained using time history analysis is larger than that obtained using spectral dynamic analysis. Accordingly, the results indicate that the structure designed with the time history analysis is heavier than the structure designed with the response spectrum analysis. Obviously, although the time history analysis provides a better understanding of the dynamic behavior of the structure, it requires much higher computational cost than the response spectrum analysis.

Abstract
Aim and Introduction
Measurement and examination of unobservable variables directly such as inflation expectations or potential output, is really challenging. Inflation expectations have been considered a key variable in many macroeconomic models, particularly in the realm of monetary economics. Macroeconomic models assume that economic agents make consumption, savings, and labor market decisions based on their perception of future inflation levels, and these decisions play a great role in realizing economic variables, including inflation. The role of inflation expectations differs from other inflation-generating factors. While factors such as money supply, budget deficit, exchange rate, and to some extent, economic sanctions can be considered as policy tools. Inflation expectations normally result from the interaction of other factors and may potentially predict future inflation. For example, an increase in the budget deficit, if not addressed independently by the Central Bank, can lead to an increase in money supply, inflation, and intensification of inflation expectations. Thus, inflation expectations can be considered as a variable that evolves within society and changes due to other inflation-generating factors. However, once formed, these expectations themselves become significant factors in inflation and other economic variables. Unlike many countries, in Iran, despite the importance of inflation due to decades of double-digit inflation, no action has been taken to produce and provide survey data related to this variable. However, according to existing literature, comparing the results of alternative methods incorporating inflation expectations with survey data can provide valuable insights. In practice, incorporating inflation expectations can improve the performance of inflation prediction models.
Methodology
Empirical research indicates that methods that consider inflation expectations along with its fluctuations and dynamics outperform models that do not consider these dynamics. Therefore, paying proper attention to how inflation expectations form and fluctuate, as well as avoiding simple methods, is necessary in calculating inflation expectations. In this research, an attempt was made to calculate and present data related to this variable in the framework of rational expectations for the period of 1996 to 2021 using the random forest regression method, considering the strengths and weaknesses of each method of mapping inflation expectations. Subsequently, after learning the random forest-based model, by conducting an in-sample prediction, the data were extracted and the features related to rational expectations regarding these data were examined.
Findings
The coefficient of determination value for the test data was found to be 80%, indicating that, on average, 80% of inflation variations are correctly predicted by economic factors using the model inputs or features. Based on this and by examining the features related to estimation residuals, it was determined that economic factors in predicting inflation do not exhibit systematic errors and, with a sufficiently large time interval and having an adequate information set, can have a proper understanding of inflation behavior. Moreover, the results of comparing inflation expectations based on random forest regression-based predictions show superiority of this approach compared to competing methods such as the Hodrick-Prescott filter. After that, the importance of each of the factors in the basket of information related to inflation expectations was ranked. It should be noted that the selection of features for predicting inflation expectations was not based on the direct attention of households and economic factors to these features. Rather, economic factors and households may find the effect of these features in other evidence. For example, the effect of an increase in the exchange rate on the prices of goods that are somehow related to this variable may be apparent to households, and fundamentally, the prevalent interpretation of rational expectations in the literature of this field is based on this approach. The results of this ranking indicate that among the entire information set, factors such as inflation breaks, exchange rates, and economic sanctions had the highest importance in shaping inflation expectations.
Discussion and Conclusion
It is worth mentioning that inflation breaks have been identified as the most important factor among the entire information set as a manifestation of the adaptive section of inflation expectations. However, this does not mean that expectations are entirely adaptive. Based on the research findings, it is clear that if economic factors rely solely on the adaptive section to predict inflation, zero estimation error, unpredictability of errors, and consequently the formation of rational expectations will not be achieved. Using a combination of three approaches: gradient boosting algorithm, random forest algorithm, and linear regression, a voting regression was also performed, showing a 3% improvement in determination coefficient compared to random forest (83%). Moreover, other results, such as the order and intensity of feature importance, and predicted inflation values, are similar to the random forest method with slight variations which means, estimating rational expectations is reliable

Abstract
During a laboratory biological study of a midge, Feltiella acarisuga (Vallot, 1827) (Diptera: Cecidomyiidae), acarivorous on two-spotted spider mites, some ceraphronid specimens were reared from the midge cocoons. A detailed morphological study and comparison with previously known species revealed that the ceraphronid is a new species of Aphanogmus Thomson, 1858 (Hymenoptera: Ceraphronidae). The new species is described as A. feltiellophagus Lotfalizadeh, sp. nov. and compared with closely related species. An identification key for all Aphanogmus species associated with predatory cecidomyiids is provided. As a parasitoid of the pupal stage of Feltiella acarisuga, the potential negative impact of A. feltiellophagus on the biological control of tetranychid mites is discussed.

Abstract
Background: Chronic Low back pain (CLBP) is one of the most prevalent health problems which is affected by psychological disorders. The aim of this study was to evaluate the role of psychological intervention on chronic low back pain among a sample of Iranian nurses.
Material and Methods: This is a randomized clinical trial. The participants of this study consisted of 84 nurses suffering from chronic back pain and working in Valiasr hospital, Tehran-Iran. The recruited nurses were randomly assigned to intervention and control groups (42 nurses in each group). The demographic questionnaire and Visual Analog Assessment scales (VAS) and a Depression Anxiety Stress Scale (DASS) were used to collect data at the beginning of the study and 3 months following completion of the intervention. Data were analyzed using Chi-square, T-test and paired T-test.
Results: Forty-two nurses, with a mean age of 32 ± 8.2 and 31.5 ± 7.4 years in the intervention group and control group respectively, took part in this study. The two groups were not significantly different at the beginning of the study in terms of demographic data (P > 0.05). At the 3-month follow up, the pain rate in the intervention group was significantly decreased from 4.47 to 4.09 (P < 0.0001). Furthermore in intervention group, the mean scores of anxiety intervention group were decreased from 17.73 to 9.76 (P < 0.0001). Decreased Stress scores decreased from 15.52 to 9.52 (P < 0.0001), and the depression score from 17.66 to 10.45 (P < 0.0001).
Conclusions: The findings of this study showed that psychological interventions reduced stress anxiety, depression as well as low back pain among Iranian nurses. It is recommended that further research with larger sample and longer follow up be conducted to confirm the findings of this study.

Abstract
In recent decades, much research has been conducted in the context of domestic violence, especially violence against women and children; But in related to another form of domestic violence, or sibling abuse, not only has little attention been paid by researchers, but most parents also ignore their children's violent behavior toward each other as a common childish behavior. However, most of these cases have profound and destructive effects on children's social development and cognition, and consequently increase the likelihood of committing criminal behaviors. Among these, social and cultural factors are a hidden phenomenon that determines the shape of individual relationships in families. The present study describes the prevalence of sibling abuse with the aim of examining the economic, cultural and social contexts of student families.
The survey study was conducted among 600 high school students in districts one and six of Mashhad using a researcher-made questionnaire in two sections: self-reported victimization and delinquency with Cronbach's alpha 0.918, and was conducted in the academic year 2020-2021. Data analysis shows that the cultural and social characteristics of families such as inadequate parental education, poverty and unemployment, affect the prevalence of sibling violence, and violence among students with lower levels of family background was more prevalent in compare to others.
This study shows that social factors and cultural level within families affect the level of violence between children; therefore, if a society can strengthen the normative and cultural components of families through education and the media, it can improve the health of families. The Iranian legislature has taken an important step to combat this type of behavioral violence by passing the Child and Adolescent Protection Act 2020.

Abstract
Background: The comparison between voluntary and automatic contraction of deep abdominal muscles in patients with Nonspecific Low Back Pain (nLBP) may the best treat for them. The aim of this case-controlled study was to compare changes in the thickness of the Transverses Abdomin is (TrA) and Internal Oblique (IO) muscles during the Abdominal Drawing-In Maneuver (ADIM) and the Active Straight-Leg Raise (ASLR) test. Methods: This study involved 30 women including 20 women with and 10 women without non-specific low back pain. The abdominal muscle thickness in the supine crook-lying, ASLR, and ADIM exercises were measured. Two-way repeated-measures ANOVA was used to compare the thickness ratio results between the two groups. Results: There were significant differences between the TrA (p < 0.05) and IO (p < 0.05) muscle thickness ratios during the ADIM compared to the ASLR in the neutral lumbar posture in supine lying in the healthy group; However, in the subjects with nLBP, only the TrA (p < 0.005) muscle thickness ratio was significantly higher in the ADIM rather than in the ASLR. Conclusion: These findings suggest that in both groups the deep abdominal muscles (the TrA and the IO) responded differently according to the variable type of activities such as voluntary or automatic, therefore, in training programs, in addition to a voluntary workout, automatic type of exercises should also be taught.

Abstract
Philosophers have defined wisdom in different ways. Most definitions refer to knowledge, but they do not agree that knowledge includes or is limited to both theoretical and practical knowledge. The definition of wisdom to understanding or to justified beliefs instead of justified true belief that is knowledge is another difference. In addition to all this, the definition of wisdom to virtue, due to its variety and complexity, is another thing that makes the definition of wisdom more difficult. Linking the discussion of wisdom with the characteristics of the sage in contemporary philosophical literature due to the various debates that have been made about the necessity of each of the components of knowledge and action further obscures the exact meaning of wisdom. While analyzing the various definitions offered by contemporary analytical philosophers on the nature of wisdom, the present article explains the relationship between wisdom and knowledge; knowledge as a necessary and sufficient condition for wisdom, a necessary but not sufficient condition, and neither necessary nor sufficient condition. Then, wisdom is considered an intellectual or epistemic virtue and a necessary condition for acquiring knowledge. After evaluation, it shows that although among the proposed states, the first state with special conditions can better express the definition of wisdom than the others, wisdom has a meaning beyond propositional knowledge. Finally, it emphasizes the importance and necessity of a more accurate explanation of this phenomenon.

Abstract
A time-domain approach is presented to calculate electromagnetic fields inside a large Electromagnetic Pulse (EMP) simulator. This type of EMP simulator is used for studying the effect of electromagnetic pulses on electrical apparatus in various structures such as vehicles, a reoplanes, etc. The simulator consists of three planar transmission lines. To solve the problem, we first model the metallic structure of the simulator as a grid of conducting wires. The numerical solution of the governing electric field integral equation is then obtained using the method of moments in time domain. To demonstrate the accuracy of the model, we consider a typical EMP simulator. The comparison of our results with those obtained experimentally in the literature validates the model introduced in this paper.

Abstract
The genus Pseudomonas consists of more than 120 species that are ubiquitous in moist environments such as water and soil ecosystems and are pathogenic to animals and humans. Within the genus of Pseudomonas, P. aeruginosa is most frequently associated with human infections. The bacterium is regarded as an opportunistic pathogen, primarily causing nosocomial infections in immunocompromised patients. The existing knowledge regarding the pathogenesis of P. aeruginosa has mainly been obtained through studying clinical isolates; particularly those involved in causing chronic lung infection in cystic fibrosis patients. Nosocomial infections commonly associated with P. aeruginosa include ventilator-associated pneumonia, catheter-associated urinary tract infections, wound infections in severe burn patients and septicaemia with their pathogenesis shown to be multifactorial. The bacterium is also capable of producing a number of toxins via the type III secretion system, as well as secreting enzymes and proteins including elastase, phospholipase C and siderophores. However, P. aeruginosa is also a waterborne pathogen, commonly found in environmental waters as well as in other sources such as sewage treatment plants. The public health implication of these bacteria whilst in the environment has not been fully investigated. Here we review our present knowledge about the pathogenesis of P. aeruginosa in clinical settings and the environment.

Abstract
Light has got the prominent significance in the Iranian beliefs throughout the history. Insistence on the light sanctity originates from the religious doctrines of pre-Islamic era (Zoroastrian beliefs) which was emphasized in the Islamic era and especially Islamic Sufism. Overall, in most religions light is the symbol of Divine Wisdom and the element of all goodness and purity; so going from darkness to brightness has been the main goal of life. Since the religion, mysticism and culture throughout the Iranian history have always been in direct relationship with the architecture of each era, the Iranian architecture has always strived to give the interior a kind of spiritual atmosphere and since no sign like the light does symbolize or manifest Divine Unity, the Islamic artists have strived to use the light in their works to make them much closer to the source of spirituality. Paying attention to light is considered as one of the most prominent features of Iranian traditional architecture, which influenced most of its structural and conceptual patterns. The construction of light-openings in the buildings such as masjids, bazaars, madrasas, and caravanserais, as the Iranian outstanding monuments, proves this very point. The Iranian master-mimars’ strategies to create the light-openings in the domes has been taken into consideration through this study. To this end, the light-openings’ exact location, according to the domes’ structural properties have been analyzed. Next, based on the foursome classification of the domes, the research theoretical framework has been determined, and the case-studies have been studied meticulously; through applying the case-studies and the combined research methods. According to the achieved results, the light-openings of the Iranian brick domes have been located at four distinguished areas, including: 1- the dome’s top, 2- the dome’s curve, 3- the dome’s shekargah and 4- the dome’s drum. Moreover, because of the structural limitations of each type of dome, the constructional techniques have played the pivotal role at locating the light-openings in the domes.

Abstract
Background: Pseudomonas aeruginosa is considered an opportunistic pathogen; several reports indicate that the organism can also cause infections in healthy hosts. Four effector proteins have been described in P. aeruginosa: exoU, exoS, exoT, and exoY. These genes that are translated into protein products related to type III secretion systems. Materials and Methods: A total of 134 samples were isolated, and P. aeruginosa was identified using biochemical tests. Bacterial genomic DNA was extracted, and the presence of the exoSand exoUgenes were detected by PCR. Biofilms were formed by culturing P. aeruginosaon glass slides in rich medium. Results: The exoU(73%), exoS (62%) genes were detected from infections caused by P. aeruginosa in urinary tract infection patients. Among the 119 strains isolated from patients with urinary tract infections. Conclusion: An improved understanding of virulence genes and biofilm formation in P.aeruginosa may facilitate the future development of novel vaccines and drug treatments.

Abstract
The subject of ethics and its principles (philosophy of ethics) is of particular importance. Ethics with Two Other Fields of Practical Wisdom (Politics and Education) for some reason it was out of the question, and it was pushed to the field of theologians and limited to the topics of prophecy and Imamate. In the modern age, the issues of moral philosophy have been at the center of philosophical issues, muslim scholars have sought to consolidate moral principles. There was three streams: Tabatabaei (a Creditable Perceptions), Motahhari (Rational good (Hosn) and evil (Ghobh) and transcendental ego), Sadr (a social approach to ethics). In this article, meanwhile refer to the aforementioned history, we introduce and analysis Sadr's perspective to ethics. Sadr is a thinker who, while familiar with Islamic philosophy, has never been confined to it. He went to solve social problems, including the foundations of ethics, to the Quran and Sunnah with free approach, and he laid a divine-social basis (public trust) for ethics.

Abstract
The present study investigates the impact of emotion, team characteristics, and team social responsibility on the team identification of the most popular teams in the Iran Pro League. To measure variables Wann and Branscombe (1993) Team Identification Scale, Lee et al. (2018) Sport Emotion Questionnaire (SEQ), Yoshida and James (2010) Team Characteristics, Lichtenstein et al. (2004) Social Responsibility, and Weimann-Saks et al. (2019) Second Screen Behavior were used. To assess content validity, five sports management researchers and the reliability of the Team identification was 0.62, second screen behavior 0.80, Team Social Responsibilities 0.91, Team Characteristics 0.67, and Emotion was 0.86. In the first part of the research, 350 fans of the most popular teams in the Iran Premier League participated using a quota homogeneous convenience sampling methodology. In the second part, 379 people were present to fit the team identification model for Persepolis F.C., 387 people for Esteghlal F.C., 335 people for Sepahan S.C., and 431 people for Tractor S.C. as samples. The findings showed that team identification impacts the second-screen behavior of fans. However, the effect of predicting team identification on each of the most popular teams in the Iran Pro League is different. In general, team identification is important in the new media space, i.e., social media, and a new form of behavioral consequences of fans, i.e., second screen behavior.

Abstract
A total of twenty seven bacterial strains were isolated from cankerous tissues of apricot, nectarine, peach, plum, sour cherry and sweet cherry trees in Tehran province and identified as Pseudomonas syringae pv. syringae (Pss), the causal agent of the bacterial canker disease, on the basis of LOPAT (levan production, oxidase test, potato rot, arginine dihydrolase and tobacco hypersensitive reaction) and GATTa's (gelatin liquefaction, aesculin hydrolysis, tyrosinase activity and Na-tartrate utilization) group tests. Pss strains showed slight differences in morphology, phenotypic (biochemical and physiological) characteristics, serological properties, plasmid DNA and cellular protein profiles and antibiogram. They were divided into three distinct groups based on hippurate and formate utilization which was correlated with protein profile in SDS-PAGE (sodium dodecyl sulfatepolyacrylamide gel electrophoresis). The virulence of Pss was significantly associated with the degree of necrosis on immature sweet cherry fruits and the rate of in vitro syringomycin production.

Abstract
Background: Pseudomonas aeruginosa is one of the main causes of nosocomial infections with a mortality rate up to 40-50%. Resistance to antibiotics is a global challenge in the treatment of infections caused by this bacterium. The Class A beta-lactamases genes, including blaSHV, blaPER, blaVEB, are the most common causes of resistance in this microorganism. This study was conducted to determine antibiotic resistance pattern and the presence of blaper, blaveb, blashv and blaoxa-10 genes in clinical isolates of P. aeruginosa isolated from patients in a hospital in Bandar Abbas.
Materials and Methods: This cross-sectional study was conducted on 72 P. aeruginosa clinical isolates. Antibiotic susceptibility testing was performed by disk diffusion method according to the clinical Laboratory Standard Institute. MIC (Minimum inhibitory concentration) of ceftazidime was performed by E-Test. Polymerase chain reaction (PCR) was performed to identify blashv, blaveb-1, blaoxa-10, and blaper-1 genes.
Results: Most of the isolates were detected from intensive care unit and urine samples. The highest resistance rate which was observed to sulfamethoxazole and ceftazidime, were 68 (94.44%) and 44 (61.11%), respectively. 27.8% of these isolates were multidrug resistance. Among 44 ceftazidime resistance isolates, 15 isolates (34%) showed MIC ≥32 µg.ml in the E- test. The prevalence rates of genes were 4.16, 12.5, 8.33, and 1.38% for blaOxa-10, blaShv, blaVeb-1, and blaPer-1 genes, respectively.
Conclusion: The ceftazidime resistance rate and the prevalence rate of resistance genes in the present study were lower than other Iranian studies. However, isolation of these genes is alarming that excessive use of antibiotics can lead to over expression of resistance genes and bacterial efflux pumps and the emergence of MDR phenotypes.

Abstract
In Nicomachean ethics, Aristotle divides the soul into two fundamental parts, the knowing part and the calculating part, the virtue of the first part is theoretical wisdom (Sophia) and the virtue of the second part is practical wisdom (Phronesis). This distinction is based on the ontological distinction between becoming and stability because the subject of practical wisdom is the realm of changeable affairs and the subject of theoretical wisdom is eternal affairs. In this research, we will first show that the intuitive intellect or Nous is the connecting factor of these two realms: Nous receives the ultimate principles from both sides, in the framework of theoretical knowledge, Nous knows the most general concepts of eternity and in the framework of Practical wisdom receives the partial individual. We will also argue that practical wisdom is the agent of realization of theoretical wisdom: Phronesis is the power of receiving the highest good, that is, the life according to the Sophia. The interpretation of the relationship between Phronesis and Sophia as a “necessary – end” suggests a way out of two conflicting interpretations of Aristotle’s ethics- the rationalist and holistic interpretation of happiness – which we will address.
