Dyad constructions provide a way of referring to pairs or groups of people based on the social relationship they share, but so far they have escaped systematization within general linguistics. This article defines and exemplifies the various kinds of dyad construction, distinguishes them from related categories (reciprocals, duals, associative duals, family group classifiers, additive co-compou...

A [70]fullerene-benzodifuranone acceptor dyad synthesized by a Ag⁺-mediated coupling reaction was used to construct a thin-film organic solar cell. The fullerene and the benzodifuranone dye in the dyad have close-lying LUMO levels in the range of 3.7-3.9 eV, so that energy transfer from the dye to the fullerene can take place. A p-n heterojunction photovoltaic device consisting of a tetrabenzop...

One of the simplest set of equations for the description of epidemics (the SEIR equations) has been much studied, and produces reasonable approximations to the dynamics of a disease. However it has long been recognised that spatial and social structure may be important if we are to fully understand the long-term persistence and detailed behaviour of a disease within a community. We will introdu...

the main objective of the present study is to elaborate the contrasts between males and females in their use of different strategies of request in english and persian and ascertain the degree to which independent variables like gender and language affect the application of these strategies during informal communication.furthermore, it offers comparable corpora which provide a good basis for cro...

The increasing prevalence of ageing stepfamilies and the potential stepchildren to act as a source support for older parents have increased interest in long-term intergenerational step relationships. Applying life-course perspective combined with Simmel’s theorizing on social dynamics, this exploratory study aims investigate preconditions cohesion is based interviews 13 parents, aged 66–79, who...

Sensory consonance and dissonance are perceptual attributes of musical intervals conveying pleasantness, tension, and harmony in musical phrases. For complex-tone dyads, corresponding to two musical notes played simultaneously, consonance is known to vary with the ratio in fundamental frequency (F0) between the two tones in the dyad. While such a relationship is well established for dyads, the ...

We reanalyzed a data set consisting of a U.S. undergraduate sample (N = 212) from a previous study (Hertenstein et al. 2006a) that showed that touch communicates distinct emotions between humans. In the current reanalysis, we found that anger was communicated at greater-than-chance levels only when a male comprised at least one member of a communicating dyad. Sympathy was communicated at greate...

The present article shows that infant and dyad differences in hand-eye coordination predict dyad differences in joint attention (JA). In the study reported here, 51 toddlers ranging in age from 11 to 24 months and their parents wore head-mounted eye trackers as they played with objects together. We found that physically active toddlers aligned their looking behavior with their parent and achiev...

The distinct contributions of histone tails and their acetylation to nucleosomal stability were examined by mechanical disruption of individual nucleosomes in a single chromatin fiber using an optical trap. Enzymatic removal of H2A/H2B tails primarily decreased the strength of histone-DNA interactions located approximately +/-36bp from the dyad axis of symmetry (off-dyad strong interactions), w...

Leader-member exchange (LMX) generally refers to the leadership process centered on the interactions between leaders and direct reports. The basic premise of high quality leader-member exchange relationships holds that direct reports gain tremendous benefits through these partnerships. LMX is perhaps the most commonly researched theory of leadership. However, few studies have specifically exami...
