The paper investigates the influence of corporate board and dissemination a separate sustainability report on disclosure (CSD) level corporations listed Egyptian index from 2016–2018. This study used score-weighting scheme assigned by Stock Exchange (EGX) to evaluate, list, rank companies in terms their CSD. Empirical results reveal that boards with higher independence larger size generate CS...

The clinical features of a migraine attack include symptoms generated by both the brainstem and the cortex. Significant changes in the activity of both brain regions during migraine have been clearly demonstrated with functional imaging techniques (1,2). How these brain regions interact before, during, and after a migraine attack remains much less clear. Cortical spreading depression (CSD), the...

The most remarkable outcome of a gene duplication event is the evolution of a novel function. Little information exists on how the rise of a novel function affects the evolution of its paralogous sister gene copy, however. We studied the evolution of the feminizer (fem) gene from which the gene complementary sex determiner (csd) recently derived by tandem duplication within the honey bee (Apis)...

Conservation and sustainable development (CSD) represent one of the most important new ways of thinking in natural resourcemanagement and policy. Cornell University has developed an interdisciplinary graduate minor to include this approach in its curriculum. The concept of CSD involves working toward environmental, social, and economic goals simultaneously. Although sustainability is sometimes ...

Cortical spreading depression (CSD) involves a slowly-propagating depolarization wave in the cortex, which can appear in numerous pathophysiological conditions, such as migraine with aura, stroke, and traumatic brain injury. Neurons and glial cells are also depolarized transiently during the phenomena. CSD is followed by a massive increase in glutamate release and by changes in the brain microc...

While most large river-deltas in the world are facing the risk of subsidence and erosion in the Anthropocene, it is suspected that the Changjiang submerged delta (CSD) could be subjected to the impacts of the world's largest dam, the Three Gorges Dam (TGD). Here we firstly indicate that the CSD went through high accumulation (1958-1978); slight accumulation (1978-1997), slight erosion (1997-200...

The complexity of social-ecological systems (SES) is rooted in the outcomes of node activities connected by network topology. Thus far, in network dynamics research, the connectivity degree (CND), indicating how many nodes are connected to a given node, has been the dominant concept. However, connectivity focuses only on network topology, neglecting the crucial relation to node activities, and ...

IMPORTANCE Patient advocacy organizations seek to increase their benefits for patients with skin disease; low awareness and patient referrals among dermatologists have presented an obstacle to this. OBJECTIVE To determine whether the Skin Advocate iPhone App would increase awareness and referrals to patient advocacy organizations in the Coalition of Skin Diseases (CSD) among Texas dermatologi...

The primary signal of sex determination in the honeybee, the complementary sex determiner (csd) gene, evolved from a gene duplication event from an ancestral copy of the fem gene. Recently, other paralogs of the fem gene have been identified in several ant and bumblebee genomes. This discovery and the close phylogenetic relationship of the paralogous gene sequences led to the hypothesis of a si...

Channel-state-dependent (CSD) radio-resource scheduling algorithms for wireless message transport using a framed ALOHA-reservation access protocol are presented. In future wireless systems that provide Mbps-class high-speed wireless links using high frequencies, burst packet errors, which last a certain number of packets in time, would cause serious performance degradation. CSD resource schedul...
