Gay men are, then sculpted by a masculinity framework that, from their early years, will not fully accept them. In an attempt to be accepted, gay men often try to make up for their homosexuality through the performance of masculinity centered on suppression of the feminine. Femmephobia, in this context, is the suppression or rejection of feminine features. In the LGBTQ＋ community, femmephobia is driven by the media and masculinity factors that are manifested in standards of attractiveness, but can also be broken down by media outlets that combat these ideas. Media has shaped gay men＇s perception of body image, standards of beauty, and have led to the progression of femmephobia within the community as a mode of restoring their masculinity that would not accept them. The introduction of alternative ideas of masculinity and gender perception are necessary for creating an inclusive form of masculinity that would promote a greater acceptance of all, and reduce femmephobia in society. Challenges against this masculinity are at work through various routes especially through the media. These venues are creating spaces where male femininity can be further explored and redefined.展开更多

Because of the uneven distribution of obstacles in the real world, the efficiency of the algorithm decreases if the global environment is represented by regular grids with all of them at the highest resolution. The framed quadtree data structure is able to more efficiently represent the environment. When planning the path, the dynamic object is expressed instead as several static objects which are used by the path planner to update the path. By taking account of the characteristics of the framed quadtree, objects can be projected on the frame nodes to increase the precision of the path. Analysis and simulations showed the proposed planner could increase efficiency while improving the ability of the AUV to follow an object.展开更多

These connectives can be used to constrain the interpretation of an utterance. They are analyzed in a broad classification outlined in discourse connectives which introduce contextual implications, which are concerned with strengthening and which introduce denials. A relevance based approach to discourse is a more adequate framework than a coherence based one for the analysis of discourse connectives.展开更多

Many of these challenges arise because the context of a transaction-related crosscutting concern consists of loosely-coupled abstractions like dynamically-generated identifiers, timestamps, and tentative value sets of distributed resources. Current aspect-oriented programming languages do not provide joinpoints and pointcuts for weaving advice into high-level abstractions or contexts, like transaction contexts. To address these problems, we propose an extension to AspectJ framework, called TransJ, that allows developers to define pointcuts in terms of transaction abstractions and that automatically keeps track of context information for transactions. This paper describes TransJ as an abstract independent framework for weaving crosscutting concerns into high-level runtime abstractions, with which developers can implement transaction-related crosscutting concerns in modular, cohesive and loosely coupled transaction-aware aspects. Finally, this paper presents eight different ways in which TransJ can improve the reuse with preserving the performance of applications requiring transactions. Informally, these hypotheses are that TransJ yields （1） better encapsulation and separation of concern; （2） looser coupling and less scattering; （3） higher cohesion and less tangling; （4） reduces complexity; （5） improves obliviousness; （6） preserves efficiency; （7） improves extensibility; and （8） hastens the productivity. A brief discussion of experiment to test the hypotheses is provided, but the details of the experiment are left for another paper.展开更多

But this return was only a turning point towards a modern understanding of the world and art from other sources. It should be noted that the problem of pictorial turn nowadays has a strong impact on the postmodern theology, which encompasses various cultural traditions, and also quite opposite philosophical attitudes. The article shows, thus, the inner relationship and connection between painting art and the search for transgression in the language that was the idea of Bataille. In the first part of this article, author tries to show the consequences of Bataille’s thinking of transgression; the second part has attempted to articulate the problems of interpretation of Picasso’s canvas Crucifixion; and concluding remarks is an attempt to review the emphasis on relationship with pictorial turn and transformations in the notion of contemporary art concerning the body as a sovereign event of the freedom and sacrifice.展开更多
