Examining Chinese Gift-giving Behavior from the Politeness Theory Perspective

This study examines how power, social distance, and ranking of imposition specified in Brown and Levinson's politeness theory influence positive and negative politeness strategies used in Chinese gift-giving. We utilize a 2 x 2 x 2 repeated measure within subject design. Responses from 152 Chinese were subjected to analyses of repeated measure ANOVAs. Results revealed significant main effects and interaction effects for power, social distance, and ranking of imposition on politeness strategies in Chinese gift-giving behaviors. Theoretical and practical implications of the results and future research directions are discussed

Characterization of the functional impact of <i>SHANK2</i> mutations in cultured neuronal cells.

<p>A. The colocalization of <i>ProSAP1A/SHANK2</i>-EGFP (postsynaptic marker) and Bassoon (presynaptic marker) indicated that the mutations did not disturb the formation of SHANK2 clusters at excitatory synapses along the dendrites. B. The quantification of synapse density was performed on 20 transfected hippocampal neurons per construct from at least three independent experiments. The majority of the <i>ProSAP1A</i> variants affecting a conserved amino acid among SHANK proteins reduced significantly the synaptic density compared with the variants that affect amino acid non conserved among SHANK proteins (Mann-Whitney U-test: n_WT = 20, n_mut = 20; U_S557N = 82.5, p_S557N = 0.001; U_R569H = 124, p_R569H = 0.04; U_L629P = 149, p_L629P = 0.17; U_V717F = 114, p_V717F = 0.02; U_A729T = 73, p_A729T = 0.000; U_K780Q = 154, p_K780Q = 0.221; U_R818H = 108, p_R818H = 0.012; U_A822T = 154.5, p_A822T = 0.224; U_V823M = 129, p_V823M = 0.056; U_Y967C = 134, p_Y967C = 0.076; U_G1170R = 78, p_G1170R = 0.001; U_R1290W = 142, p_R1290W = 0.121; U_Q1308R = 162, p_Q1308R = 0.314; U_D1535N = 97, p_D1535N = 0.005; U_P1586L = 137, p_P1586L = 0.910; U_L1722P = 79, p_L1722P = 0.001, *p<0.05, **p<0.01, ***p<0.001). <b>C.</b> Effect of the variants on synaptic density. The y-axis represents −log P compared to WT (P obtained with Mann-Whitney test). After Bonferroni correction for 16 tests, only P values<0.003 were considered as significant. Variants represented in red were specific to ASD, in orange were shared by ASD and controls, and in green were specific to the controls.

Genetic alterations identified in the control subject SWE_Q56_508.

<p>A. <i>SHANK2</i> splice mutation (IVS22+1G>T) detected in a Swedish female control, SWE_Q56_508.

B. CNVs in the same individual altering <i>LOC339822</i>, <i>SNTG2</i>, <i>PXDN</i> and <i>MYT1L</i>. The two close duplications span 264 kb and 245 kb on chromosome 2 and altered <i>LOC339822</i> and <i>SNTG2</i>, and <i>PXDN</i> and <i>MYT1L</i>, respectively. Dots show the B allele frequency (BAF; in green), Log R ratio (LRR; in red), and QuantiSNP score (in blue).

<p>Mutations in <i>SHANK1-3</i> are associated with a gradient of severity in cognitive impairment. <i>SHANK1</i> mutations were reported in patients without ID (green dots). <i>SHANK2</i> mutations were reported in patients with mild ID (orange dots). <i>SHANK3</i> mutations were found in patients with moderate to severe deficit (red dots). Black dots correspond to the patients enrolled in the PARIS cohort screened for deleterious <i>SHANK1-3</i> mutations (n = 498).

Summary of the SHANK protein functions and of the main findings obtained for patients with ASD.

<p>The frequency of mutation in patients and control individuals was calculated from the total cohort (<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004580#pgen-1004580-t001" target="_blank">Table 1</a>). The frequency of mutation in patients with normal IQ (IQ>70) and low IQ (IQ<70) were calculated for the patients with available IQ scores (copy-number variants for all SHANK: nASD with IQ>70 = 1 638 & nASD with IQ<70 = 917; SHANK1 coding-sequence variants: nASD with IQ>70 = 354 and nASD with IQ<70 = 278; SHANK2 coding-sequence variants: nASD with IQ>70 = 335 & nASD with IQ<70 = 344; SHANK3 coding-sequence variants: nASD with IQ>70 = 667 & nASD with IQ<70 = 611). The mean IQ and standard deviation was given only for patients carrying truncating or <i>de novo</i> mutations. The black star indicates that Schmeisser et al.
