Women's communication in Mexican organizations

This study attempts to derive a communication profile of women in Mexican organizations of the private sector. The questions that guided the study were the following: (1) Do women perceive their communication behaviors as similar to or different from those of men at their same organizational level? (2) If women do perceive differences, what is their nature? (3) Do perceived similarities to and differences from men vary by organizational level? Forty-five women in 14 Mexican organizations were intensively interviewed in the winter of 1980. The interviews were distributed equally at three organizational levels—secretarial, middle management, and upper management. It was found that women respondents perceive themselves to differ from men on 18 of 40 verbal and nonverbal communication variables. The average woman in this study perceived that verbally she is more courteous, cheerful, assertive, careful, likely to talk with males, self-confident, and directive than men, and that she expresses less agreement than men. Nonverbally, the average woman was found to look more at the eyes, smile more, give more attention to dress, be more punctual and flexible than men, and to be less rigid in posutre, touch less, invite co-workers to her home less, and take less work home. Organizational level differences were also found. The results are discussed in the light of the theoretical paradigms presented in the study.     

Activation of CB1 specifically located on GABAergic interneurons inhibits LTD in the lateral amygdala

Previously, we found that in the lateral amygdala (LA) of the mouse, WIN55,212-2 decreases both glutamatergic and GABAergic synaptic transmission via activation of the cannabinoid receptor type 1 (CB1), yet produces an overall reduction of neuronal excitability. This suggests that the effects on excitatory transmission override those on inhibitory transmission. Here we show that CB1 activation by WIN55,212-2 and Delta(9)-THC inhibits long-term depression (LTD) of basal synaptic transmission in the LA, induced by low-frequency stimulation (LFS; 900 pulses/1 Hz). The CB1 agonist WIN55,212-2 blocked LTD via G(i/o) proteins, activation of inwardly rectifying K+ channels (K(ir)s), inhibition of the adenylate cyclase-protein kinase A (PKA) pathway, and PKA-dependent inhibition of voltage-gated N-type Ca2+ channels (N-type VGCCs). Interestingly, WIN55,212-2 effects on LTD were abolished in CB1 knock-out mice (CB1-KO), and in conditional mutants lacking CB1 expression only in GABAergic interneurons, but were still present in mutants lacking CB1 in principal forebrain neurons. LTD induction per se was unaffected by the CB1 antagonist SR141716A and was normally expressed in CB1-KO as well as in both conditional CB1 mutants. Our data demonstrate that activation of CB1 specifically located on GABAergic interneurons inhibits LTD in the LA. These findings suggest that CB1 expressed on either glutamatergic or GABAergic neurons play a differential role in the control of synaptic transmission and plasticity.     

Legal abortion worldwide: incidence and recent trends

CONTEXT: Information on abortion levels and trends can inform research and policies affecting maternal and reproductive health, but the incidence of legal abortion has not been assessed in nearly a decade. METHODS: Statistics on legal abortions in 2003 were compiled for 60 countries in which the procedure is broadly legal, and trends were assessed where possible. Data sources included published and unpublished reports from official national reporting systems, questionnaires sent to government agencies and nationally representative population surveys. The completeness of country estimates was assessed by officials involved in data collection and by in-country and regional experts. RESULTS: In recent years, more countries experienced a decline in legal abortion rates than an increase, among those for which statistics are complete and trend data are available. The most dramatic declines were in Eastern Europe and Central Asia, where rates remained among the highest in the world. The highest estimated levels were in Armenia, Azerbaijan and Georgia, where surveys indicate that women will have close to three abortions each on average in their lifetimes. The U.S. abortion rate dropped by 8% between 1996 and 2003, but remained higher than rates in many Northern and Western European countries. Rates increased in the Netherlands and New Zealand. The official abortion rate declined by 21% over seven years in China, which accounted for a third of the world's legal abortions in 1996. Trends in the abortion rate differed across age-groups in some countries. CONCLUSIONS: The abortion rate varies widely across the countries in which legal abortion is generally available and has declined in many countries since the mid-1990s.
