Temporal analysis of lambda sigma activity systems

Abstract: lambda sigma is a simulation language based on Whitehead's (1960) theory of reality and formalized in the typed lambda -calculus. lambda sigma entities are described as elements of a type and lambda sigma activities are subtypes. Type inference algorithms can be used to analyze and verify models in which the flow of entities is deterministic. In this paper, the authors describe the use of temporal logic to analyze and verify models in which entities move from one activity to another with a given probability. The approach is to apply the proof system for temporal logic with uncertainty of Lehmann and Shelah (1982). >

Synthesis and crystal structures of 2-(ferrocenyl-carbon-yl)benzoic acid and 3-ferrocenylphthalide

Abstract: The title compounds, 2-(ferrocenylcarbon­yl)benzoic acid, [Fe(C5H5)(C13H9O3)], 1, and 3-ferrocenylphthalide [systematic name: 3-ferrocenyl-2-benzo­furan-1(3H)-one], [Fe(C5H5)(C13H9O2)], 2, have been synthesized and structurally characterized by single-crystal X-ray diffraction. The crystal structure of compound 1 was solved recently at room temperature [Qin, Y. (2019). CSD Communication (CCDC deposition number 1912662). CCDC, Cambridge, England]. Here we report a redetermination of its crystal structure at 90 K with improved precision by a factor of about three. The mol­ecular structures of both compounds exhibit a typical sandwich structure. In the crystal packing of compound 1, each mol­ecule engages in inter­molecular hydrogen bonding, forming a centrosymmetric dimer with graph-set notation R22 (8) and an O⋯O distance of 2.6073 (15) A. There are weak C—H⋯O and C—H⋯π inter­actions in the crystal packing of compound 2. The phthalide moiety in 2 is oriented roughly perpendicular to the ferrocene backbone, with a dihedral angle of 77.4 (2)°.

Lucille

Abstract: The percentage of the population in the United States comprised of older adults (65+), sometimes referred to as Baby Boomers (birth year 1946 – 1964) and the Silent Generation (birth year 1925 – 1945), is steadily on the rise. This population is often overlooked and has a unique subset of issues when it comes to counseling competencies. Layered multicultural competencies affecting these individuals include race, gender, sexual orientation, religion, and ageism. Counseling concerns related to age include but are not limited to loss of autonomy, loss of physical ability, loss of loved ones, and changing definition of self. From an existential therapeutic background blended with Cognitive Behavioral Therapy (CBT) interventions, the author reviews the case study of Lucille with a focus on therapeutic intervention and Multicultural and Social Justice Counseling Competencies (MSJCCs).

Philosophy, mathematics, science and computation

Abstract: Attempts to lay a foundation for the sciences based on modern mathematics are questioned. In particular, it is not clear that computer science should be based on set-theoretic mathematics. Set-theoretic mathematics has difficulties with its own foundations, making it reasonable to explore alternative foundations for the sciences. The role of computation within an alternative framework may prove to be of great potential in establishing a direction for the new field of computer science. Whitehead's theory of reality is re-examined as a foundation for the sciences. His theory does not simply attempt to add formal rigor to the sciences, but instead relies on the methods of the biological and social sciences to construct his world-view. Whitehead's theory is a rich source of notions that are intended to explain every element of experience. It is a product of Whitehead's earlier attempt to provide a mathematical foundation for the physical sciences and is still consistent with modern physics. A computer simulation language is, in fact, a theory of reality; one that is often based on extremely simplistic notions. Simulation languages have evolved from the various programming languages and not from the development of their underlying world-view. The use of an established theory of reality, such as Whitehead's, as the basis of a simulation language is proposed as a way of extending the usefulness of computer simulation as an experimental tool for the theory. The λσ simulation language is a first step in this direction. Based on Whitehead's notion of concrescence and a formalization in the typed λ-calculus, λσ provides a notation and method for the construction and simulation of real-world phenomena. Both philosophy and computer science stand to benefit from such an attempt. Whitehead's theory gains a testing tool, while computer science gains a significantly more advanced simulation language.
