• Migration, Place and Class: Youth in a Rural Area

  The claims that locality, kinship, and social class are no longer the basis of ties that bind and of limited significance for identity in late modernity, remain seductive, despite their critics. Those who remain rooted are then presented as inhabitants of traditional backwaters, outside the mainstream of social change. This article presents young people's reasons for leaving or remaining in a rural area of Britain, the Scottish Borders. Young people's views about migration and attachment demonstrate a contradictory and more complex pattern than that of detached late-modern migrants and traditional backwater stay-at-homes. These stereotypes have some resonance in local culture, for example in disdain for rootless incomers lacking real sympathy with ‘the community’ and in the common accusation of the parochial narrow mindedness of locals who have never been elsewhere. However, such stereotypes emerge from complex social class antagonisms and cross-cutting ties to locality. Many young people's ties contradict the classifications these stereotypes imply. There are young out-migrants who are the children of ‘rootless’ in-migrants, but also, nevertheless, have lasting attachments to the locality of their childhood. Then there are young ‘stayers’ who are the children of ‘born and bred’ locals but yet feel serious disaffection from their locality. These ‘attached migrants’ and ‘detached stayers’ may not represent settled orientations to their locality of childhood, but they, nevertheless, contradict both certain local stereotypes and Baumanesque ‘late modernist’ sociological theorising.

  地方性、亲属关系和社会阶层不再是联系的基础，在晚期现代性中对身份认同的意义有限，尽管这些说法受到了批评，但仍然具有诱惑力。于是，那些仍然扎根于此的人就被视为传统落后地区的居民，游离于社会变革的主流之外。本文介绍了年轻人离开或留在英国农村地区--苏格兰边界地区的原因。与离群索居的后现代移民和传统的穷乡僻壤的留守者相比，年轻人对移民和依恋的看法表现出一种矛盾和更复杂的模式。这些刻板印象在当地文化中引起了一些共鸣，例如，对无根之人的蔑视，他们对 "社区 "缺乏真正的同情，以及对从未去过其他地方的当地人狭隘思想的普遍指责。然而，这种刻板印象源于复杂的社会阶层对立和与当地的交叉联系。许多年轻人的联系与这些刻板印象所暗示的分类相矛盾。有些外迁青年是 "无根 "内迁青年的子女，但他们也对童年生活的地方有着持久的依恋。还有一些年轻的 "留守者"，他们是 "土生土长 "的本地人的子女，但却对自己的家乡感到严重的不舍。这些 "依恋的移民 "和 "疏离的留守者 "可能并不代表他们对童年所在地的固定取向，但他们却与当地的某些刻板印象和鲍曼式的 "晚期现代主义 "社会学理论相矛盾。

• Photodissociation of <i>N</i>-(Triphenylmethyl)anilines:  A Laser Flash Photolysis, ESR, and Product Analysis Study¹

  N-(Triphenylmethyl)anilines (Ph3C-NHPh-R, R = H, o-Me, m-Me, p-Me, p-CPh3), upon photolysis with 248- and 308-nm laser light, as well as by lamp irradiation with 254-nm light in acetonitrile and hexane solutions, undergo exclusively C-N bond homolysis to give the triphenylmethyl radical in a monophotonic process. Product analysis gives as main products Ph3CH, 9-Ph-fluorene, and PhNH2. The quantum yields for the formation of Ph3C. are high (0.6-0.8, 248-nm excitation) and independent of the solvent. This effective homolytic dissociation results from the low electronegativity difference between the carbon and nitrogen atoms constituting the bond to be broken, the low bond dissociation enthalpy of the C-N bond, the high excitation energy of the local chromophore (aniline), and probably from a favorable alignment of the C-N bond in a plane perpendicular to the anilino chromophore (due to the large steric requirements of the trityl group), thus enabling an effective hyperconjugative interaction with it. The above dissociation competes effectively with heterolytic cleavage, which is the pathway dominating, e.g., in the photolysis of Ph3C-Cl in MeCN under the same conditions. At high pulse intensities the trityl radicals formed above are excited by a second photon leading to either electrocyclization to 4a,4b-dihydro-9-phenylfluorenyl radical (DHPF.), or photoionization to PhaC(+), the latter only in MeCN and only on 248-nm photolysis. A new intermediate (9-Ph-4aH-fluorene) on the way to the final product 9-Ph-fluorene is identified resulting from electrocyclization, supporting a mechanism proposed earlier. The optical measurements are supported by ESR studies (irradiation with 254-nm light).
