Interstitial insertion of varying amounts of ABL-containing genetic material into chromosome 22 in Ph-negative CML.

We studied the cells from three selected patients with Ph-chromosome-negative chronic myeloid leukemia (CML) by Southern blotting, polymerase chain reaction, and in situ hybridization of informative probes to metaphase chromosomes. All three patients had rearrangement of M-BCR sequences in the BCR gene and expression of one or other of the mRNA species characteristic of Ph-positive CML. Leukemic metaphases studied after trypsin-Giemsa banding were indistinguishable from normal. The ABL probe localized both to chromosome 9 and 22 in each case. A probe containing 3' M-BCR sequences localized only to chromosome 22, and not to chromosome 9 as would be expected in Ph-positive CML. Two new probes that recognize different polymorphic regions distal to the ABL gene on chromosome 9 in normal subjects localized exclusively to chromosome 9 in two patients and to both chromosomes 9 and 22 in one patient. These results show that Ph-negative CML with BCR rearrangement is associated with insertion of a variable quantity of chromosome 9 derived material into chromosome 22q11; there is no evidence for reciprocal translocation of material from chromosome 22 to chromosome 9.

Resource Curse or Destructive Creation: A Tale of Crony Capitalism in Transition

This paper explores the “resource curse” problem as a counter-example of creative performance and innovation by examining reliance on capital and physical resources, showing the gap between expectations and ex-post actual performance became clearer under conditions of economic turmoil. The analysis employs logistic regressions with dichotomous response and predictor variables, showing significant results.Several findings that have use for economic and business practice follow. First, in a transition period, a typical characteristic of successful firms was their reliance on either capital resources or physical asset endowments, whereas the innovation factor was not significant.Second, poor-performing enterprises exhibited evidence of over reliance on both capital and physical assets. Third, firms that relied on both types of resources tended to downplay creative performance. Fourth, reliance on capital/physical resources and adoption of “creative discipline/innovations” tend to be mutually exclusive. In fact, some evidence suggests that firms face more acute problem caused by the law of diminishing returns in troubled times. The Vietnamese corporate sector’s addiction to resources may contribute to economic deterioration, through a downward spiral of lower efficiency leading to consumption of more resources. The “innovation factor” has not been tapped as a source of economic growth. The absence of innovations and creativity has made the notion of “resource curse” become identical to “destructive creation” implemented by ex-ante resource-rich firms, and worsened the problem of resource misallocation in transition turmoil.

The body language: The spontaneous influence of congruent bodily arousal on the awareness of emotional words

Nowadays, the idea of a reciprocal influence of physiological and psychological processes seems to be widely accepted. For instance, current theories of embodied emotion suggest that knowledge about an emotion concept involves simulations of bodily experienced emotional states relevant to the concept. In line with this framework, the present study investigated whether actual levels of physiological arousal interact with the processing of emotional words. Participants performed 2 blocks of an attentional blink task, once after a cycling session (increased arousal) and once after a relaxation session (reduced arousal). Concretely, participants were instructed to detect and report 2 target words (T1 and T2) presented among a series of nonword distractors. T1 and T2 were either neutral, high arousal, or low arousal words. Results revealed that increased physiological arousal led to improved reports of high arousal T2 words, whereas reduced physiological arousal led to improved reports of low arousal T2 words. Neutral T2 remained unaffected by the arousing conditions. These findings emphasize that actual levels of physiological arousal modulate the cognitive access to arousal (in-)congruent emotional concepts and suggest a direct grounding of emotion knowledge in our bodily systems of arousal.
