Separation anxiety in families with emerging adults

In several developmental theories separation anxiety has been identified as an important feature of close interpersonal relationships. Most often, separation anxiety has been examined in the context of mother-child dyads in infancy. Increasingly, however, it is recognized that separation anxiety is also relevant in other relationships (e.g., the father-child relationship) and in later developmental periods (e.g., adolescence and emerging adulthood). The present study aimed to investigate separation anxiety at the family level in families with emerging adults. By using the Social Relations Model, we aimed to determine the extent to which the actor, the partner, their specific relationships, and the family contribute to separation anxiety in dyadic family relationships. A total of 119 Belgian two-parent families with an emerging adult participated in a round-robin design, in which family members reported on their feelings of separation anxiety towards each other. Findings showed that separation anxiety can be represented as a personality attribute (i.e., an actor effect) and as a specific feature of the mother-child dyad. Further, findings indicate that separation anxiety is also characteristic of the father-mother marital relationship and of the family climate as a whole. Implications for the meaning of separation anxiety and clinical practice are discussed

Failure to launch, failure to achieve criteria for adulthood?

In the West it is not until the mid-20s or 30s people reach an adult status. Becoming an adult signifies being independent from others (especially from parents) and learning to stand alone as a self-sufficient person. This study investigates whether the attainment of such individual qualities are affected by emerging adults’ living circumstances. Results indicate that though independent living is associated with an accelerated achievement of certain criteria for adulthood, continued coresidence with parents during emerging adulthood slows down the process by which an individual moves toward becoming a self-sufficient and independent adult. Because success in the achievement of an adult status also positively predicts emerging adults’ well-being, delayed home-leaving during this stage of life is an issue that requires special attention

Fe65: A Scaffolding Protein of Actin Regulators

The scaffolding protein family Fe65, composed of Fe65, Fe65L1, and Fe65L2, was identified as an interaction partner of the amyloid precursor protein (APP), which plays a key function in Alzheimer’s disease. All three Fe65 family members possess three highly conserved interaction domains, forming complexes with diverse binding partners that can be assigned to different cellular functions, such as transactivation of genes in the nucleus, modulation of calcium homeostasis and lipid metabolism, and regulation of the actin cytoskeleton. In this article, we rule out putative new intracellular signaling mechanisms of the APP-interacting protein Fe65 in the regulation of actin cytoskeleton dynamics in the context of various neuronal functions, such as cell migration, neurite outgrowth, and synaptic plasticity

The bounds for the distance two labelling and radio labelling of nanostar tree dendrimer

The distance two labelling and radio labelling problems are applicable to find the optimal frequency assignments on AM and FM radio stations. The distance two labelling, known as L(2,1)-labelling of a graph A, can be defined as a function, , from the vertex set V(A) to the set of all nonnegative integers such that (, ) represents the distance between the vertices c and s in where the absolute values of the difference between () and () are greater than or equal to both 2 and 1 if (, )=1 and (, ) = 2, respectively. The L(2,1)-labelling number of , denoted by 2,1 (), can be defined as the smallest number j such that there is an (2,1) −labeling with maximum label j. A radio labelling of a connected graph A is an injection k from the vertices of to such that (, ) + |() − ()| ≥ 1 + ∀ , ∈ (), where represents the diameter of graph . The radio numbers of and A are represented by () and () which are the maximum number assigned to any vertex of and the minimum value of () taken over all labellings k of , respectively. Our main goal is to obtain the bounds for the distance two labelling and radio labelling of nanostar tree dendrimers
