まとめ
予想とは対照的に,大都市では社会経済的隔離が高くなります. 都市デザイン,特にハブの配置は,曝露の多様性に影響することによって,この分離を増加させたり減少させたりすることができます.
科学分野:
- 都市社会学
- 人類の地理
- コンピュータ社会科学
背景:
- 広大で密集した都市圏は 社会経済的な混在を促すという 長い仮説があります
- 以前の研究では 社会的経済的な混ざり合いの理解を制限する 実生活への曝露ではなく 静的な居住データに基づいていました
研究 の 目的:
- 現実世界の移動データを用いて,新種の被曝分離測定法を開発し,適用する.
- 都市規模と社会経済的暴露の多様性との関係を調査する.
- 都市部における社会経済的な隔離に影響を与える要因を特定する.
主な方法:
- 日常の接触に基づく 曝露分離の尺度を開発した.
- 携帯電話の移動データを利用し,米国の960万人の間での16億回の暴露を示しました.
- 382の都市統計地域 (MSA) と2829の郡における被曝分離を分析した.
主要な成果:
- 小規模MSAと比較して,最大10のMSAでは,被曝分離が67%高い.
- 大都市部に住む人々は 日常生活の中で 社会経済的な多様性が少なくなります
- 大都市における隔離の増大は,社会経済的差異のあるスペースのより大きな選択と結びついています.
- 都市の中心部を戦略的に配置することで,多様な社会経済集団を惹きつけることで 隔離を緩和することができます.
結論:
- 大規模で多国籍的な地域は 社会経済的な混在を促すという 伝統的な考え方に異議を唱えます
- 都市デザインと公共スペースの空間構成は,社会経済的な多様性に影響を及ぼします.
- 都市計画における介入は,より大きな社会経済的統合を促進するために活用できます.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Overview Of Cell Separation And Isolation
5.7K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.
