BACKGROUND Cell-fate determination requires that cells choose between alternative developmental pathways. For example, germ cells in the nematode worm Caenorhabditis elegans choose between mitotic and meiotic division, and between oogenesis and spermatogenesis. Germ-line mitosis depends on a somatic signal that is mediated by a Notch-type signaling pathway. The ego-1 gene was originally identif...

The paper defines altruism as charity. The second section of the paper criticizes three rationalistic (what is called ‘‘interactional’’) theories of altruism, viz., the egoistic, egocentric, and altercentric perspectives. The third section criticizes three normative (what is named ‘‘selfactional’’) theories of altruism, viz., the Kantian, the socialization argument, and ‘‘warm glow’’ story. The...

ego identity defined as a fundamental element of a person and as self-continuum, mental andinward image that an individual has about him or herself. this subject investigated in contemporary world, amply.for actualizing and testing this concept, four bases including achievement, moratorium, foreclosure and diffusionintroduced and based on this framework, and the effect of different factors on e...

Gene expression profiling of early eosinophil development shows increased transcript levels of proinflammatory cytokines, chemokines, transcription factors, and a novel gene, EGO (eosinophil granule ontogeny). EGO is nested within an intron of the inositol triphosphate receptor type 1 (ITPR1) gene and is conserved at the nucleotide level; however, the largest open reading frame (ORF) is 86 amin...

A study was conducted to examine the joint influence of psychosis-proneness and ego strength on creativity in college students. Psychosis-proneness and ego strength were defined psychometrically by means of Minnesota Multiphasic Personality Inventory and California Psychological Inventory profile, a procedure that resulted in creation of four categories of research subjects: (I) psychosis-prone...

Finding the global optimum(s) of a non-convex function is of great importance in numerous applications in science and engineering where the function takes the form of an expensive computer code and its inputs are the independent variables. For this type of problem, Jones et al. [12] proposed the idea of expected improvement (EI) and embedded it in an algorithm called efficient global optimizati...

INTRODUCTION: A critical importance has been attached to altruism and organizational learning capability in the improvement of organizational performance. In light of this significance, the present study investigated the effect of altruism on organizational learning capability with the mediating role of communication conflict and organizational trust in Red Crescent provincial branches of Gilan...

Because carbon emissions create externalities across countries and generations, climate policy requires international cooperation and intergenerational altruism. A differential game using overlapping generations with intergenerational altruism shows how altruism and cooperation interact, and provides estimates of their relative importance in determining equilibrium steady state carbon levels. A...

AIMS The experience of a compromised sense of "self", termed ego-dissolution, is a key feature of the psychedelic experience. This study aimed to validate the Ego-Dissolution Inventory (EDI), a new 8-item self-report scale designed to measure ego-dissolution. Additionally, we aimed to investigate the specificity of the relationship between psychedelics and ego-dissolution. METHOD Sixteen item...

Our civilization is facing substantial risks and a growing realization of how climatological ecological tipping points can fundamentally change the premises for life. This rapidly emerging reality compels shift in scope concern humans. Even so, it remains unclear whether our ability to learn, collaborate, address complex problems compatible with this endemic crisis. Here, we existential dilemma...
