The growing global population presents a significant challenge to ensuring food security,further compounded by the increasing threat of salinity to agricultural productivity.Wheat,a major staple food providing 20%of the total caloric intake for humans,is susceptible to salinity stress.Developing new salttolerant wheat cultivars using wheat breeding techniques and genetic modifications is crucial to addressing this issue while ensuring the sustainability and efficiency of wheat production systems within the prevailing climate trend.This review overviews the current landscape in this field and explores key mechanisms and associated genetic traits that warrant attention within breeding programs.We contend that traditional approaches to breeding wheat for Na^(+)exclusion have limited applicability across varying soil salinity levels,rendering them inefficient.Moreover,we question current phenotyping approaches,advocating for a shift from whole-plant assessments to cell-based phenotyping platforms.Finally,we propose a broader use of wild wheat relatives and various breeding strategies to tap into their germplasm pool for inclusion in wheat breeding programs. 展开更多

The spatial pattern of trees is an important feature of forests,and different spatial patterns of trees exhibit different ecological stability.Research has confirmed that natural forests with random patterns have higher biodiversity and stronger resistance to unstable factors such as pests and diseases.Even if they are disturbed or destroyed by unstable factors such as pests and diseases,they can still recover and rescue themselves;while artificial forests with uniform and clustered patterns have lower biodiversity and are susceptible to unstable factors such as pests and diseases.And once pests and diseases occur,it’s more difficult for them to recover.In order to promote the healthy and stable develop-ment of the forestry industry and protect the diversity of the biological environment,it is necessary to protect the random pattern of natural forests from being destroyed in the process of forest management,while effectively transforming the spatial pattern of artificial forests into a random pattern.Therefore,in order to ensure the convenient and accurate determination of the type of forest spatial pattern,research on methods for determining forest spatial pattern has become particularly important.Based on the theory of uniformity,this study proposes definitions and related theories of included exclusive sphere,included exclusive body,included random pattern,and included uniformity.Under the guidance of the definition of inclusion uniformity and related theories,and by using mathematical method,it is proved that the uniformity of inclusion(CL)is asymptotically subject to the Eq.18,Therefore,the relationship between the included uniformity(CL)and the number of trees in the sample plot was established,and the corresponding relationship formula was obtained,and then the determination of the spatial pattern type of trees was completed by using the corresponding relationship formula.Through rigorous reasoning and case verification,the determination method of forest spatial pattern is effective. 展开更多

Edible plant derived exosome-like nanoparticles(ELNs)have been shown to have multiple nutraceutical functions.However,the diversity of plant materials makes the plant derived ELN study challenging.More efforts are still needed to explore the feasible isolation methods of edible plant derived ELNs and the possible roles of food-derived ELNs in improving human health.In this study,a size exclusion chromatography based method was compared with the traditional ultracentrifugation method to isolate blueberry derived ELNs(B-ELNs),and the miRNA profile of B-ELNs was analyzed by high-throughput sequencing.A total of 36 miRNAs were found to be enriched in B-ELNs compared with berry tissue,and their potential cross-kingdom human gene targets were further predicted.Results showed that size exclusion chromatography was effective for B-ELN isolation.The most abundant miRNAs in B-ELNs mainly belonged to the miR166 family and miR396 family.Target gene prediction indicated that B-ELNs could potentially regulate pathways related to the human digestive system,immune system and infectious diseases. 展开更多

Interference management is one of the most important issues in the device-to-device(D2D)-enabled heterogeneous cellular networks(HetCNets)due to the coexistence of massive cellular and D2D devices in which D2D devices reuse the cellular spectrum.To alleviate the interference,an efficient interference management way is to set exclusion zones around the cellular receivers.In this paper,we adopt a stochastic geometry approach to analyze the outage probabilities of cellular and D2D users in the D2D-enabled HetCNets.The main difficulties contain three aspects:1)how to model the location randomness of base stations,cellular and D2D users in practical networks;2)how to capture the randomness and interrelation of cellular and D2D transmissions due to the existence of random exclusion zones;3)how to characterize the different types of interference and their impacts on the outage probabilities of cellular and D2D users.We then run extensive Monte-Carlo simulations which manifest that our theoretical model is very accurate. 展开更多

Appropriate feeding practices are important during infancy for good health, growth and development of infants and children. WHO revised its earlier recommendation of Exclusive Breastfeeding (EBF) of infants from 4 to 6 months of age to EBF until about 6 months of age, with the addition of complementary foods thereafter. This recommendation confirms that breast milk alone is sufficient to meet infants’ nutritional requirements for the first 6 months of life. The main objective of this study was to investigate the effect of various feeding practices on the Nutritional status of infants 0 - 12-month-old in the Kumba 1 Sub-Division. A descriptive cross-sectional study was conducted from December 2019 to August 2020. A total of 341 nursing mothers and their infants 0 - 12 months of age were recruited. Socio-demographic factors and the different feeding habits of the children were assessed using a semi-structured questionnaire. Nutritional status was assessed using anthropometric measurements. The overall proportion of infants who exclusively breastfed for 6 months was 69.2% and those who were mix-fed were 30.8% in the study area. The overall prevalence of malnutrition in the population was 61.0%. Among the malnourished children, 53.1% were underweight, 19.6% were wasted and 10.0% were stunted. Though not significant, the prevalence of wasting (21.0%) and underweight (58.3%) was higher among Mix-Fed (MF) children when compared to their EBF counterparts. Feeding practices affected the nutritional status of the infants. Underweight and wasting were observed among infants on Complementary Feeding (CF), although some exclusively breast-fed infants were stunted. Hence, nursing mothers should try as much as possible to practice EBF as recommended by WHO and can practice CF when the child is above six months. 展开更多

Introduction: Neonatal mortality remains a major concern in West Africa, and exclusive breastfeeding is recognized as a crucial intervention to promote newborn survival. This study aims to identify the factors influencing the practice of exclusive breastfeeding among mothers, as well as the perceptions of fathers, in the Boulmiougou health district. Method: This cross-sectional mixed study was conducted between May and July 2022, involving 471 mothers and 103 fathers of children under one year of age. Questionnaires and interviews were used to collect data. Results: The practice of exclusive breastfeeding was observed in 44.6% of mothers surveyed. Logistic regression analysis revealed that mothers older than 26 years have a significantly higher chance of exclusive breastfeeding [adjusted OR = 1.7;95% CI: (1.098 - 2.685);p = 0.019] compared to mothers under 26 years of age. Similarly, mothers with at least three antenatal visits were 2.715 times more likely to perform exclusive breastfeeding than those with less than three antenatal visits [adjusted OR = 2.715, 95% CI: (1.184 - 6.225);p = 0.018]. The vast majority of fathers (76.7%) were informed about exclusive breastfeeding, and 59.5% had a correct definition. The analysis of the father’s perception highlighted a stronger focus on traditional practices in 90.3% of cases than on medical recommendations. Conclusion: In light of these results, it is essential to increase sessions to raise awareness and involve men throughout pregnancy, childbirth and early childhood monitoring about the many benefits of exclusive breastfeeding. 展开更多

The current situation of European educational systems leads to the lack of historical precedents,considering that it implies the end of educational systems based on exclusion,configuring a new conception of educational systems that we are still not able to appreciate at their true value,because we were educated by and in the previous educational system.Lacking other references,we inevitably tend to compare current problems with previous situations,without understanding that the generalization of education to 100%of the population implies a qualitative change that modifies the objectives,forms of work,and the very essence of the educational system.This stage change,marked by the acceleration of social changes,including the pandemic situation,explains why,despite the best educational system so far,teachers with the best levels of training and a financial and material endowment unimaginable until recently,try a sense of crisis and a general feeling of confusion is manifested among the teachers and parents of the children,seeing that education is no longer what it used to be(Esteve,1998).The key to defuse this apparent paradox is in the tendency to judge the new education system by the mentality and standards of the former selective education,in which most of the adults present were educated.Thus,although we continue to apply to the new general education situation the parameters of the previous situation,in which the selective system excluded every year the students who had behavior problems in the class or had difficulties regarding the mastery of certain educational subjects(Esteve,1998).In this way,we are currently criticizing the school failure of a percentage of our students,without realizing that their schooling itself is a success,because,although their level is low,they had no level before.One speaks of a low educational level,when,in reality,the educational level is increasing—the general level of the people and the individual level of the best students(Baudelot&Establet,1990).Indeed,it is true that in our education systems there are students with a very low educational level,although even so,it is a success that they have some education because they used to be on the streets;and,in any case,the current education system produces a higher percentage of students with higher levels than the best students of the 90s.The main element of change,the most substantial transformation,is the elimination of exclusion,today having access to secondary education,alongside students with an excellent level.Thousands of children who were previously expelled from it,thus comply with the European measures of access to education for all children and young people.The previous educational system can be compared to a hospital from which the sickest were kicked out,and those who created behavioral problems were eliminated through the selective mechanisms of the system.However,teaching today is qualitatively different from what it was 20-30 years ago.First of all,because working with a homogeneous group of children as a result of the selection or dealing with all the children in a country,with social and personal problems,is not the same thing.That is why many general education teachers are social workers rather than teachers;and the new configuration of our educational systems requires secondary teachers to assume diverse educational roles rather than the traditional one of intellectual training.History cannot go backwards;to have better quality educational systems,the solution is not to return to the exclusionary system.Society asks teachers to make an effort to integrate;but,during this time,our society must support and revalue the activity of teachers in order not to put them in front of impossible tasks.The transition from a selective to a general education was based on the increase/amplification of compulsory schooling.For the first time in history,European educational systems have assumed the role of declaring secondary education compulsory.This decision implies a new stage,a definitive break from the previous reality in which secondary education was reserved for those who later attend a university. 展开更多

This paper reveals that the implementation of inclusive education is an unfinished challenge,both within the system and for individual self-improvement.This process of changing practices,by continually questioning the school’s responsibility for the(re)production of inequalities,exclusion,and unequal social relations,is riddled with obstacles,unpredictable situations,and strong emotions.In particular,the researchers point out that many systemic mechanisms of school culture contribute to replicating and reifying hierarchical school experiences and exacerbating processes of institutional discrimination against immigrant backgrounds and/or racialized students.The empirical research presented also highlights the school staff’s deficit thinking toward immigrant students and their parents.The results show that staff tend to use linguistic and cultural gaps between students and the school system to explain academic failure.Be that as it may,the researchers as well as the school actors and students interviewed in this paper suggest multiple ways to improve inclusion in the school context,stressing the importance of giving voice to the various actors in order to move toward institutional transformation. 展开更多

This paper presents the results of a research project on the intercultural climate in schools and the academic success of immigrant students in Quebec.The intercultural climate in eight secondary public schools is documented from the standpoint of various school and community stakeholders,students,and parents.More specifically,the paper focuses on the commitment to promoting cultural equity,which is identified through interviews with the targeted stakeholders on exclusionary practices and processes and the practices implemented to counter them.The results identify five areas of vulnerability among certain minoritized groups of students:the transition from welcoming to regular classes for those students learning French,evaluation and support for those experiencing learning or behavioral difficulties,the referral of these students to adult education programs or work-oriented training programs,their participation in extracurricular activities,and their access to special school projects.Nonetheless,some schools do report the introduction of many equity practices in response to the exclusionary ones.However,these initiatives are mostly occasional and voluntary and pertain to interactions between individuals.These findings call for a discussion on the importance of systemic and concerted initiatives towards achieving equity. 展开更多

The recognition of the positive value of student diversity and their right to full participation are key aspects of inclusion as a means of managing heterogeneity of the school population from an equality perspective.As the school cannot welcome the diversity of children without including their families,the same logic needs to apply to the relationship between the school and parents,particularly in the current environment where the school-family partnership appears as a privileged institutional leverage in the fight against inequalities at school.Based on an ethnographical study exploring how the relationship between the school and the families builds up in a Swiss school located in a context of strong cultural diversity,this paper interrogates how the school norm can be the main limitation to the inclusion of students and parents who are unfamiliar with the school.Derived from field observations and interviews,our results show how the teachers tend to approach their relationship with new students and their parents from the standpoint of narrowly defined expected models,leading them to engage in a vain attempt to conform the students and parents when they deviate from these models.The possibility of entering the school system for students and parents unfamiliar with school is hindered by the exclusive and excluding normativity on which the models of the child and the parent expected by the teachers are grounded.Based on these observations,we discuss how an inclusive approach seems to us to require in the first place a necessary process of decentering from the school and teachers,as a condition for recognition of the actual child and parent. 展开更多

In connection with the historical context of social segregation and the assimilative aim of formal education imposed on them,the Indigenous Peoples of Québec have long been excluded from higher education.Today,even if their graduation rates are increasing,a persistent gap with the non-Indigenous population is maintained.The data in this article are drawn from 23 interviews with students and university graduates of the First Nations of Québec,as part of a thesis in educational sciences.Our paper analyzes how these students manage to combine the contributions of Indigenous education with those of Western education by developing paths that are part of the decolonization movement of education.Their relationship to Indigenous identity and cultures clearly influences their educational background and is analyzed taking into account power relations with the dominant culture.Our paper emphasizes more particularly the relationship to studies,the adaptation to the student profession,and the balance between studies,work,and family among Indigenous students,in a context of transition from university to multiversity which contributed to the increase of Indigenous university attendance. 展开更多

The school placement processes of students from immigrant backgrounds considered to be in“difficulty”is an international concern at the intersection of works relating to special education and those concerning the school experiences of students from immigrant backgrounds or racialized groups.The research problem of this article concerns the identification of these students as disabled or as having adjustment or learning difficulties.From a perspective anchored in Disability Critical Race Studies,this ethnographic study documents different interpretations of perceived difficulties made by school actors with regard to seven primary school students from immigrant backgrounds.Five interpretation types are presented:(1)medicalization by dismissal of cultural markers,(2)medicalization by professional constraint,(3)medicalization by cultural deficit,(4)precautionary wait,and(5)cultural differentialism.Our results help to shed light on the special education overrepresentation phenomenon regarding these students and to understand how ableism and(neo)racism contribute to it. 展开更多

In recent years,Francophone schools in Alberta,a province in western Canada,have seen significant ethnocultural diversification of their school population,thus reflecting recent migratory changes in Canada.The population of a Francophone school board located in an agglomeration of Alberta reflects these new migratory trends.A partial ethnodemographic portrait carried out in 2003 in six of its schools indicates that 50%of the pupils come from an immigrant background and come from 23 different countries;mostly from sub-Saharan African countries.This demographic reality,confirmed more than a decade later,represents a major structural change for Francophone schools.In Alberta,as in other Canadian provinces,inclusion is at the heart of discourse and educational practices.With a transformative aim,it intends to promote ethnocultural diversity in the classroom and equal opportunities through school equity practices.This article focuses on the settlement workers in schools responsible for bridging family,community,and school cultures.The analysis of the interviews of the four workers sheds light on and questions both the institutional practices and the personal strategies put in place to face the challenges encountered in this tripartite collaboration. 展开更多

A new integrity metric for navigation systems is proposed based on the measurement domain. Proba-hilistic optimization design offers tools for fault detection by considering the required navigation performance (RNP) parameter and the uncertainty noise. The choice of the proper performance parameter provided the single-valued mapping with the missed detection probability estimates the probability of failure. The desirable characteristics of the residual sensitivity matrix are exploited to increase the efficiency for identifying erroneous observations. The algorithm can be used to support the performance specification and the efficient calculation of the integrity monitoring process. The simulation for non-precision approach (NPA) validates both the viability and the effectiveness of the proposed algorithm. 展开更多
