We introduce and study a tactic language, Hitac, for constructing hierarchical proofs, known as hiproofs. The idea of hiproofs is to superimpose a labelled hierarchical nesting on an ordinary proof tree. The labels and nesting are used to describe the organisation of the proof, typically relating to its construction process. This can be useful for understanding and navigating the proof. Tactics...

This study expands the exploration of a consumer behavior concept that has received considerable attention recently: fear missing out (FoMO). Several variables were analyzed in terms their potential influence on FoMO: social media usage, self-concept, identity, smartphone innovativeness, and gender.

The Beowulf model for clusters of commodity computers[15, 17, 18] has become very popular over the last year, particularly amongst university research groups and other organisations less able to justify large procurements. The Beowulf concept is usually applied[16] to clusters of Personal Computers running Linux, but other platforms and operating systems can also be considered as providing simi...

We describe an emerging problem in globally distributed operating systems: the conflict between user requirements and administrative requirements. Then we describe the key to the solution: user-level resource aggregation. Next we outline the requirements of such a solution, and then we describe our specific implementation of the solution, which we call Snowflake. Finally, we discuss the metrics...

In 2015, the Self-Action Leadership Theory—a qualitative, nomological expansion of selfleadership theory rooted in atmospheric and astronomical metaphor aimed at expanding the personal freedom of individuals, organizations, and nations by bolstering the existential growth of individuals through a series of Maslow-esque stages of holistic, personal development. This article introduces an accompa...

I cannot be in the company of still active Yale colleagues without having far too many memories. To suffer reminiscences, Freud noted, is to suffer neurosis, and this should probably not be inflicted-even on deserving friends! Nor has Fritz Redlich done anything so drastic, in spite of being busted in bronze and hung in portraits, for us not to celebrate his astonishingly productive present. I ...

In this article, I briefly review theories about the development of theory mind, and then examine evidence for minimalism, idea that infants initially understand only behaviors. To end, consider need a wide variety species to predict behaviors other animals human are not unique in regard. also discuss infants' understanding behaviors, including their good statistical learning skills rich exposu...
