Variable particle masses have sometimes been invoked to explain observed anomalies in low energy nuclear reactions (LENR). Such behavior has never been observed directly, and is not considered possible in theoretical nuclear physics. Nevertheless, there are covariant off-mass-shell theories of relativistic particle dynamics, based on works by Fock, Stueckelberg, Feynman, Greenberger, Horwitz, and others. We review some of these and we also consider virtual particles that arise in conventional Feynman diagrams in relativistic field theories. Effective Lagrangian models incorporating variable mass particle theories might be useful in describing anomalous nuclear reactions by combining mass shifts together with resonant tunneling and other effects. A detailed model for resonant fusion in a deuterium molecule with off-shell deuterons and electrons is presented as an example. Experimental means of observing such off-shell behavior directly, if it exists, is proposed and described. Brief explanations for elemental transmutation and formation of micro-craters are also given, and an alternative mechanism for the mass shift in the Widom–Larsen theory is presented. If variable mass theories were to find experimental support from LENR, then they would undoubtedly have important implications for the foundations of quantum mechanics, and practical applications may arise.

This paper is concerned with the conceptualisations of space which underlie debate of gentrification-related displacement. Using Derrida's concept of the spatial metaphor, the paper illuminates the Cartesian understandings of space that act as architecture for displacement debate. The paper corrects this through arguing that the philosophy of Heidegger and Lefebvre better serves to understand displacement. Emphasising the topology of Heidegger's Dasein and, following Elden, relating this to Lefebvre's understanding of space, the paper 'constructs' displacement in a way that avoids the abstraction of displacement-as-out-migration and instead emphasises the lived experience of space.

Over the last thirty years, personal debt loads have increased dramatically. Lower income earners borrow money to purchase basic goods and services, so their debt is frequently non-discretionary. The impact of non-discretionary personal debt on debtors can be as, if not more, harmful than government regulations that have been declared unconstitutional. In this regard, the impact of personal debt is tantamount to the impact of a civil rights violation. What separates the impact of unconstitutional state action from that of personal debt is the assumption that only the latter are the result of consensual transactions. Consent, however, is not a dyadic phenomenon, it exists in gradations. The quality of consent is weakened when the agent is making choices in response to pressures, and the empiricalquestion of the extent to which a consent transaction is unforced is distinct from the normative question of whether a transaction is legitimate, or fair. It is necessary to devise a new taxonomy of language to clearly distinguish the empirical and normative questions. This elucidates the fact that lower income people are under more pressure to borrow money than are upper income individuals to pay progressive rates of income tax. To argue that the latter are ‘coerced,’ is to admit that the low income individual’s decision to borrow is similarly forced. This admission suggests that a significant portion of citizens of market-based economies (notably Canada and the U.S.) are being forced to endure harms tantamount to civil rights violations. The admission also suggests that free markets harbour forces that undermine individual autonomy, and the absence of corrective state regulation exacerbates the problem.
