武汉市一般人群血清中全氟及多氟烷基化合物浓度及其影响因素研究

目的 了解武汉市一般人群血清中全氟及多氟烷基化合物(PFASs)浓度,探索血清中PFASs浓度水平的影响因素。方法 以在武汉市某医院进行一般体检的人群为研究对象(n=67),通过超高效液相色谱-三重四级杆质谱(UPLC-TQ/MS)联用仪测定外周血清中12种PFASs浓度,采用多元线性回归分析方法分析一般人口学特征和血清中PFASs浓度的关联性。结果 武汉市一般人群血清中12种PFASs的平均浓度水平为11.60 ng/mL。全氟辛烷磺酸及其盐类(PFOS)和全氟辛酸及其盐类(PFOA)的贡献率较大,分别为45.03%和31.86%。男性人群血清中PFOS、PFOA、全氟己基磺酸(PFHxS)、全氟壬酸(PFNA)等主要化合物的浓度高于女性,其β值(95%可信区间)分别为0.708(0.313,1.104)、0.518(0.069,0.967)、0.724(0.388,1.059)和0.684(0.399,0.968)。同时,发现血清中PFOS、PFHxS、PFNA浓度和年龄呈正相关,其β值(95%可信区间)分别为0.062(0.042,0.081)、0.035(0.019,0.052)和0.030(0.016,0.045)。结论 性别和年龄对血清中PFASs浓度有影响,在进行人体PFASs暴露评估中应考虑这些因素。     

Gender and support for creativity at work

Although innovation is vital for the success of organizations, many may not be capitalizing on the creativity of all workers. Gender bias in attributions of creativity may lead to an imbalance in the extent to which organizations support the creativity of men and women. Because organizational support for creativity is positively associated with creative outcomes, this may undermine the creativity of women in the workplace. To determine if gender influences creative workplace behavior through support for creativity, conditional process models were used to analyze the survey responses and external employment data of workers (N = 14,590) across industries in the US. Our analyses demonstrate that men report greater support for creativity in the workplace than women, and greater support for workplace creativity leads to more frequent creative workplace behaviors. The proportion of women employed in an industry influences this relationship, such that differences between men and women become smaller as the proportion of women in an industry increases. However, the level of creativity required in an occupation does not influence the relationship between gender and creativity. The theoretical and practical implications of these results are discussed.     

Taking back the power: an analysis of Black women’s communicative resistance

Black women are a structurally oppressed group in a subordinate position in the power hierarchy. Language is an important demonstration of group identity and is used to manage the day-to-day realities of being both Black and women. Scholars have devoted attention to explaining why Black women’s discursive practices are a function of their particular vantage point and can serve as a measure of protection against social and political hostilities. While there is a great deal of research acknowledging Black women’s ability to resist, the work can be extended by analyzing the specific resistance strategies Black women employ in common social environments. This essay uses Black/feminist standpoint and power and discourse frameworks to analyze Black women’s communicative resistance across three communication contexts: (1) education, (2) workplace, and (3) personal relationships.     

Similarities and differences between male and female novice designers on color‐concept associations for warnings,action required,and signs and equipment status messages

This research examined the male and female novice designers toward color associations for the concepts used for ‘warnings’, ‘action required’, and ‘signs and equipment status’ through a questionnaire‐based study. A total of 178 Hong Kong Chinese final year undergraduate design students (89 males and 89 females) participated in the study. The test used required the participants to indicate their choice of one of nine colors to associations with each of 38 concepts in a color‐concept table, so that any one color could be associated with any one of the concepts. For both male and female groups of novice designers, chi‐square tests revealed a strong color association for each concept tested in this study (P < .05). The results showed males and females agreed on some color‐concept association stereotypes which were therefore gender neutral. The male and female novice designers had the same color associations and similar levels of stereotype strengths for 21 concepts. The nine strongest and therefore most useful color‐concept association stereotypes for both male and female novice designers were: red‐danger, red‐fire, red‐hot, red‐stop, red‐emergency, red‐error, blue‐cold, blue‐male, and green‐exit. However, the male and female novice designers had different color association stereotypes for the standby (green vs. yellow), emergency exit (green vs. red), and toxic (purple vs. black) concepts, and the strengths of the 14 remaining associations for both groups were not at equivalent levels. Overall, it is anticipated that the findings of this study will act as a useful reference for novice designers and other design practitioners to optimize color coding in the design of ‘warnings’, ‘action required’, and ‘signs and equipment status’ messages.     

Gender difference in color preference across cultures: An archetypal pattern modulated by a female cultural stereotype

A gender difference in color preference among British participants has been repeatedly reported, in which both males and females show a preference for blue‐green colors, while females express an additional preference for pink‐purple colors. To investigate the robustness of gender difference in color preference in a different culture, we tested 81 young adult Indians from a school of design and compared them to 80 young British students in Psychology. The 35‐item International Personality Item Pool (IPIP) and Bem Sex Role Inventory (BSRI) questionnaires were also administered to explore possible links between personality traits, gender schemata, and color preferences. Results confirmed a gender difference in both cultures; participants collectively expressed a preference for cool over warm colors, while in addition females showed a preference for pink colors, with a warm bias for Indian females and a cool bias for British females. While these results extend gender difference to Indian culture and support the universality of an underlying pattern they also reveal a culture‐specific contribution essentially observed in females. In British participants, color preference was correlated exclusively with BSRI scores in females and overwhelmingly with IPIP scores in males; this gender‐specific pattern of correlation was not replicated in the Indian sample. Results point to an archetypal pattern of gender difference in color preference with a remarkable cross‐cultural similarity in men and a subtle but significant cultural difference in women whose origin is yet to be explained.

Site operatives’ attitudes towards traditional masculinity ideology in the Australian construction industry

There is a widely accepted assumption in the construction literature that the industry is highly masculinised. However, there has been a surprising lack of empirical evidence around workers’ own attitudes towards masculinity in the sector. Addressing this lack of research, a survey to measure construction site operatives’ attitudes towards traditional masculinity ideology was undertaken in Australia using the Male Role Norms Inventory Scale-Short Form (MRNI-SF). It is found that the focus of attitudes towards masculinity in the construction industry may be shifting to reflect trends in the wider population and may be more inclusive and less hegemonic than has been previously argued. It is also found that the focus of masculinity in the construction industry is closely related to the physical and high-risk nature of work and that sexuality and humour may also be an important source of masculine identity. These results are important since they contribute a more nuanced understanding of the dimensions and exact nature of attitudes towards masculinity in the construction industry. It is concluded that future research into the impact of masculinity in areas such as gender diversity, safety and mental health would benefit from a more inclusive theoretical lens which recognises the dynamic nature of masculinity and which highlights the institutional legacies of past hegemonies that have to be challenged to move the industry forward.
