However, despite this aspiration, all people still face different problems. Some of these come from his fellow human beings and in modern States, everyone must be protected from acts that infringe his rights and freedoms. To avoid arbitrariness, States have long established various institutions to promote and protect human rights. Indeed, the judiciary is the keystone but to be effective, one of the conditions that it must fulfill remains independence. Despite both international and national instruments advocating the independence of the judiciary, this issue remains problematic in Burundi as elsewhere. This article has been prepared to analyze the Burundian population's perception of the independence of judiciary power by highlighting different points of view from the diverse representative sample. Intellectuals especially politicians, lawyers, and judicial practitioners fully understand the concept of the independence of the judiciary, the provisions that guarantee it, and their factors while Unintellectual people are less familiar with it. Nevertheless, all the people met doubt the effectiveness of the independence of the judiciary if they","PeriodicalId":49860,"journal":{"name":"Mathematical Models & Methods in Applied Sciences","volume":"9 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90427356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead of considering its original form, whose study of the one-dimensional parameter space has recently received new insights, we examine the Nos´e-Hoover model slightly modified by using a new parameter (cid:15) to introduce a dissipative term to its energizing-damping variable. We use the maximum Lyapunov exponent to numerically characterize the chaotic dynamics of the model, at representative points of the two-dimensional parameter space, treating separately two dynamical regimes resulting from: (i) the effect of lower values of (cid:15) and (ii) the effect of higher values of (cid:15) . It is shown that, for higher values of the new dissipative parameter (cid:15) , the existence of chaotic behavior only prevails for the backwards dynamics.","PeriodicalId":49860,"journal":{"name":"Mathematical Models & Methods in Applied Sciences","volume":"126 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86067693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of them are fleeing insecurity in their country of origin. As required by the UNHCR Handbook on International Refugee Protection and the Strengthening of National Asylum Systems, these refugees are entitled to adequate reception conditions that meet their basic needs and provide them with a decent standard of living in terms of health and welfare, pending a final decision on their asylum claim. After the reception, they must file their asylum applications as soon as possible with the Burundian asylum authorities, namely the Consultative Commission for Foreigners and Refugees (CCER) and the Appeal Committee (CR). To determine refugee status, these two asylum bodies base themselves on legal instruments, international, regional and national ones. One wonders then which of these legal instruments is used more in the determination of refugee status in Burundi. The analysis focused on the origin of the asylum seekers, on the legal basis of reference in the motivation of the decision as well as on the link between the place of reception of these asylum seekers and the decision taken. To select these files, we took into account the date of arrival of the asylum seekers (old and new) and their country of origin.

Its importance in the socio-economic balance of households is not to be denied. Atmospheric changes and rainfall instability keep agriculture exposed to climate stress and its consequences. Captured through exposure, sensitivity, and adaptive capacity, vulnerability is nothing more than a predisposition to experience damage. The exposure of agriculture in the sense of vulnerability is of two kinds. It is both intrinsic and extrinsic. This refers to the conceptual definition that vulnerability is both a factor specific to agriculture and a characteristic of the farmer himself. In addition to the sector, there are the socio-demographic and economic characteristics of each farmer. This article assesses the moderating role of associative dynamics on the coping strategies and level of vulnerability of farmers in the highland area of the Baswagha Chiefdom, in Lubero territory, Democratic Republic of Congo. The data presented are from a survey of 409 heads of households in 5 groups. The results are such that associative dynamics modify the direction of the relationship between coping strategies and vulnerability of farmers, who are exposed at 62.05%; sensitive at 57.54%; have a coping capacity of 35.45%, and are, therefore, vulnerable at 38.36%.","PeriodicalId":49860,"journal":{"name":"Mathematical Models & Methods in Applied Sciences","volume":"87 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80645290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, demand is taken as selling price dependent. The effect of inflation is also taken into consideration. We developed a sustainable inventory model with a cap-and-trade policy. The model aims to find the optimal inventory level for a retailer that balances economic sustainability and environmental responsibilities. By considering the cost of carbon emissions and the financial impact of inventory levels on the company, the model helps managers make informed decisions about inventory control that support both economic and environmental goals. The numerical illustration is carried out by using the software Mathematica 12.0.
