Despite work’s importance in people’s overall sense of purpose in life, several studies measuring momentary well-being find that people are very unhappy while at work. These studies have focused on workers in industrialized countries doing paid labor in the formal sector. For a large fraction of humanity, however, “work” is smallholder farming, tending cattle and collecting water and fuelwood. We measure momentary well-being with the Experience Sampling Method in a sample of 195 subjects in rural Kenya. Subjects were the household’s main water carrier; 93% were women. Each subject was asked to complete four ESM surveys per day over eight weeks. Results from 9559 ESM records show that subjects are indeed less happy “at work”, whether that work is paid or unpaid casual labor, paid formal sector employment, or resource collection. They are also less energetic, less sociable and in more pain. We also find evidence that subjects perceive themselves as less safe while working or traveling away from home. We find a statistically significant, though small, relationship between the intercepts in the model (individual-level average momentary well-being) and the log of household wages earned over the past two weeks. The relationship is stronger with wages earned by the subject herself.
相似文献Men seek help for problems less often and more hesitantly than women across a wide range of contexts. While there are many potential sources for this gender discrepancy, one possibility is that masculine attitudes and behaviors discourage help-seeking behaviors and create help-seeking barriers. As the superhero genre often changes over time to reflect current social attitudes, the current study explores patterns, contexts, and rewards of help-seeking behaviors portrayed by men in a genre of media frequently consumed by men: superhero films. Twenty-three Marvel Cinematic Universe films were coded for superhero men’s help-seeking behaviors, as well as patterns in context and outcomes around help seeking. Overall, we found that superhero men displayed the help-seeking behaviors of approaching problems and collaboration with others most often, followed by the maladaptive coping strategy violence. In addition, help-seeking behaviors were most often displayed when the superhero was acting in his personal/self, capacity and superhero men were most often confronted with physical problems. Furthermore, we found that most of the help-seeking behaviors coded were rewarded only about half of the time. Finally, we found several differences in patterns of help-seeking displayed by various specific heroes. Other patterns and implications are discussed.
