Birth-death models are central to much macroevolutionary theory. The fundamental parameters of these models concern durations. Different species concepts realize different species durations because they represent different ideas of what birth (speciation) and death (extinction) mean. Here, we use Cenozoic macroperforate planktonic foraminifera as a case study to ask: what are the dynamical cons...

In this paper, I show how the subsystem concept of UML may be adapted for architectural modeling. Previous approaches used stereotypes of UML’s class-concept instead. For greater conceptual clarity, I pursue an explicit metamodeling approach. However, the modifications I propose could be reformulated using only UML’s standard extension mechanisms, If that were desired. The present approach is i...

Predominantly, a school provides pedagogical support to its students, though perceptions about the school’s internal environment can incessantly influence student’s aggregated learning experience. The present study aims investigate impact of campus on students’ engagement and roles self-concept clarity intentional self-regulation this association. A hypothetical model relationship between perce...

The central aim of this review was to consider whether theories developed within mainstream aggression research might also be usefully applied in the prediction of violence amongst a mentally disordered population. Current understanding of the relationship between mental illness and violence suggests that our knowledge could be advanced by consideration of factors beyond those intrinsic to diag...

The author explores the presence and the essential tension between clarity and ambiguity as processes within our minds that become prominent in psychoanalysis. We learn from aesthetics and literary criticism that ambiguity can shade from taut disorganization to tolerating life's richness; clarity can range from a concrete fixity to a lucid grasp of one's state of mind. This article responds to ...

The method for finding fuzzy optimal solution of fully fuzzy critical path (FFCP) problems i.e., critical path problems in which all the parameters are represented by fuzzy numbers, is at best scant; possibly non-existent. In this paper, a method is proposed to find the fuzzy optimal solution of FFCP problems, together with a new representation of triangular fuzzy numbers. This paper will show ...
