Outward-oriented economies seem to grow faster than inward-looking ones. Does the literature on convergence have anything to say on this? In the dynamic Heckscher-Ohlin-Samuelson model، with factor-price equalization، there is no convergence of incomes. This is because with identical preferences and return to capital، irrespective of initial levels the growth rates of consumption are the same. In the Specific Factors model، there is factor price equalization in the long run، but incomes depend on endowments of non-accumulable factors. Different specifications for the intersectorally mobile factors have different implications for development (as well as convergence).
Resistance to Deforestation Represented in Louis Owens’Wolfsong: An Eco-Critical Reading(مقاله علمی وزارت علوم)
Deforestation has been one of the most detrimental consequences of the prevalence of European anthropocentrism in North America. European settlers who immigrated to North America found themselves in a bountiful paradise with infinite untrammeled natural resources that could be utilized to make a fortune. Likewise, they inflicted irremediable damages on nature upon the onset of their settlement in this continent. Investigating Louis Owens’ Wolfsong from an ecocritical standpoint, this article seeks to highlight the massive deforestation conducted by the white Americans in the Northwest of the United States of America. As a qualitative, research-based study, this article commences with the theoretical framework and subsequently focuses on the representations of the critical concepts in Wolfsong . It shall be indicated that the perspective held by the White Americans towards nature drastically collides with that of the indigenes. More exactly, the argument of this research follows the distinction between the treatment of nature by the Euro-Americans and Native Americans in Wolfsong .
Eco-critical Praxis: Unravelling and Recuperating Eco-trauma in Leslie Marmon Silko’s Gardens in the Dunes(مقاله علمی وزارت علوم)
This article unravels the concept of eco-trauma in American Indians’ lifestyle in Gardens in the Dunes (2000), a novel portraying eco-concerns of Leslie Marmon Silko (1948). Silko’s novel is preoccupied with ecological concerns of American Indians who depend on nature to continue their existence. Being detached from their ancestral lands, Indians encountered several psychological problems due to their indispensable loyalty to nature. This article focuses on the significance of environment and ‘place’ according to Lawrence Buell (1939), and traces ‘place’ as the center of feeling for a person. Cheryll Glotfelty’s connection between nature and culture, and Cathy Caruth’s perspective on trauma have been utilized to explain Indians’ psychological problems due to loss of ancestral lands. Eco-traumatic approach illustrates the interrelation of Native American’s identity and culture with their living place. Indeed, Indians return to their land to eliminate their environmental concerns. Their ceaseless effort to reverse eco-trauma by adhering to their ancestral ritual is also examined in this article. Silko re-emphasizes and stipulates that the notion of nature can consolidate Indians’ identity; hence, loyalty to natural environment ensures how Native Americans’ loss of land and nature opens up the experience of eco-loss or eco-trauma and diminishes Native Americans’ culture.
Ecosystem and the Change of Lifestyle: Adwiata Mallabarman’s A River Called Titash, Manik Bandyopadhyay’s The Boatman of the Padma, and Syed Waliullah’s Cry, River, Cry(مقاله علمی وزارت علوم)
Adwaita Mallabarman’s (1914-1951) Titash Ekti Nadir Naam (1956), translated by Kalpana Bardhan as A River Called Titash (1993), Manik Bandyopadhyay’s (1908-1956) Padma Nadir Majhi (1936), translated by Ratan K. Chattopadhyay as A Boatman of the Padma (2012), and Syed Waliullah’s (1922-1971) Kando Nadi Kando (1968), translated by Osman Jamal as Cry, River, Cry (2015) are novels which portray the identity of the people of Bangladesh who live by the side of the rivers Titash, Padma, and Bakal. The biodiversity of these rivers was once resourceful, but they lost their flow because of the imbalance in the river ecosystems for siltation, drought, and deforestation. The lifestyles and identities of fishermen and people are greatly influenced by the change of river ecosystems. Different writers in Bengali literature have written about the changes of human life in connection with the flow of different big and small rivers. Mallabarman writes about fisherman (Malo) community who catch fish in the Titash; Bandyopadhyay portrays the identity of fishermen who catch fish in the Padma; and Waliullah writes about the farmers and the people who depend on the movement of steamers and live by the side of a tributary called Bakal. These three novelists show beautiful landscapes of Bengal in different seasons and also show how people become victims with the change of biodiversity and ecosystems. This paper explores the change of the ecosystem of the rivers Titash, Padma, and Bakal which change the lifestyle of the people who are dependent on them.
Investigating the Impact of the Islamic Revolution of Iran on "Land Policy" in Rural Areas(مقاله علمی وزارت علوم)
حوزههای تخصصی:
Land and "Land Policy" have always been important social issues that are related to and dependent on the policies and governance models of different countries. In contemporary Iranian history, the issue of land has always been an unresolved matter and a focus of the government's attention. The significance and sensitivity of this issue led policymakers to immediately address it after the Islamic Revolution, and the specific legal, social, and political concerns in this area prompted the formulation and implementation of a new policy for land distribution in rural areas of the country. Given the importance of this topic, the central theme of this research is the transformations that occurred in the field of rural land ownership in Iran under the influence of the Islamic Revolution, with the main goal of examining the impact that the phenomenon of the Iranian Islamic Revolution had on land policy in Iran. Therefore, the main question of this article is ‘What was the land policy of the Islamic Republic of Iran in rural areas and on what principles, foundations, and implementation methods was it based?’ In response to this question, using a comparative method, we have addressed the land policy of the Islamic Republic of Iran in rural areas and ultimately examined this policy by presenting a model.
تغییرات فضایی-زمانی دمای میانگین در سراسر ایران : مقایسه تطبیقی گذشته دور و نزدیک(مقاله علمی وزارت علوم)
حوزههای تخصصی:
تغییر اقلیم به عنوان یکی از چالش های اساسی جهان، به دگرگونی های پایدار در الگوهای آب وهوایی اشاره دارد که تأثیرات عمیقی بر محیط زیست، اقتصاد و جوامع انسانی برجای می گذارد. هدف از مطالعه حاضر، تحلیل و مقایسه میانگین دمای ایران در دو دوره زمانی متمایز، یعنی گذشته دور (1965 تا 1994) و گذشته نزدیک (1995 تا 2024) و همچنین تحلیل روند این تغییرات به صورت ماه به ماه و سالانه در سراسر ایران می باشد. در این تحقیق از داده های شبکه بندی بازکاوی ERA5-Land استفاده گردید. نتایج نشان داد، در گذشته نزدیک نسبت به گذشته دور، میانگین دما در ایران افزایش یافته و این افزایش در ماه های مختلف بین 5/0 تا ۱ درجه سلسیوس متغیر بوده است. در گذشته دور (1965-1994)، دمای برخی ماه ها مانند فوریه، مارس، مه و اکتبر روندی ثابت یا کاهشی داشته، اما در گذشته نزدیک، تمام ماه های سال، عمدتاً افزایش دما را نشان می دهند. یافته ها نشان داد که تقریبا از سال ۲۰۰۰ به بعد، ناهنجاری دمایی ماهانه و سالانه به طور پیوسته روندی مثبت و افزایشی داشته است که ماه های گرم سال به ویژه جولای و آگوست، بیشترین مقدار ناهنجاری مثبت را نشان می دهند اما در سال های پیش از آن، ناهنجاری ها نوسانی و شامل مقادیر مثبت و منفی بوده است. روند تغییرات سالانه دما نیز از حدود صفر درجه سلسیوس در دوره گذشته دور، به 35/0 درجه سلسیوس در هر دهه در دوره اخیر رسیده است که نشان دهنده گرمایش چشمگیر و پایدار است. این روند رو به رشد، اهمیت اتخاذ سیاست های موثر برای کاهش اثرات منفی گرمایش جهانی و برنامه ریزی های دقیق در بخش های زیست محیطی و اقتصادی کشور را دوچندان می کند.
