英国社会学essay代写社会生态模型是一个理论框架，它关注决定行为和社会关系的个人因素和环境因素的多面互动作用。它由从个人到全球的相互关联的层次构成，展示了社会系统的活力和生态维度(联合国儿童基金会C4D, 2009年)。每一层都与其他层动态交互，说明某一层的因素如何影响相邻层的其他因素(CDC, 2019)。使用的社会生态模型有许多不同的版本，大多数版本有五个层次。核心或最内在的层次是个体，连续的层次与主体有更广泛的关系。为了在整个研究过程中保持一致性，我们将使用Bronfenbrenner引入的社会生态模型。Bronfenbrenner社会生态模型中的不同层次的个体,他们的微系统关系的家人,同事,可能学校和教堂是相关的,中度系统是集中在当地社区,exosystem处理国家一级计划和宏观系统水平与全球政策环境(McCallen, 2016)。该模型已广泛应用于社会科学，从用于创建暴力预防框架(CDC, 2019)到用于高等教育的关键成功标准(McCallen, 2016)。这表明指数能力的社会生态模型作为一个有用的理论框架。汤森和福斯特在2010年完成的研究利用了这个模型，并将其整合到研究设计和分析中。在这项研究中，研究人员采用了六个层次的影响，以便能够在学校和其他相互作用的因素中充分促进健康饮食。该研究类似地使用该模型来实现多层分析，以努力创建一个更广泛的结果，不同层次的解释相对于它们与其他层次的关系。在本研究中，社会生态模型在研究设计的创建和分析中起着至关重要的作用。该模型具有层级性，但在各个层次之间有动态的交互作用，它将允许对“欢迎城市”倡议中内置的可能性进行全面评估。倡议的支持者指出，考虑到移民在当代的重要意义，该倡议具有广泛的全球相关性。该模型易于拟合和适应评价和问题求解，因此在应用研究中非常有用。这个框架支持对数据的跨级别解释和分析，以及在制定政策以改进主动性和根据当地环境定制政策方面的使用。
The Social Ecological Model is a theoretical framework that focuses its attention on the multifaceted and interactive effects of the personal and environmental factors that determine behaviours and social relations. It consists of a hierarchy of interrelated levels from the individual to the global level demonstrating the dynamism and ecological dimensions of social systems (UNICEF C4D, 2009). Each level is dynamically interactive with the other levels illustrating how factors from one level influence other factors from an adjacent level (CDC, 2019). There have been a multitude of different versions of the social ecological model used, with most versions having five levels. The core or innermost level is the individual with successive levels having a wider scope in relation to the subject. For uniformity throughout the research, the social ecological model introduced by Bronfenbrenner will be used. The different levels in Bronfenbrenner’s Social Ecological Model are the individual, their microsystem relationship where the family, peers, possibly school and church are related, the mesosystem which is concentrated on local community, the exosystem that deals with national level initiatives and the macrosystem level which relates to the global policy environment (McCallen, 2016).The model has been used extensively in the social sciences from being used in the creation of a framework for prevention of violence (CDC, 2019) to being used as critical success criteria in higher education (McCallen, 2016). This shows the exponential capacity of the Social Ecological Model as a useful theoretical framework. The research done by Townsend and Foster, 2010, utilised the model integrating it into its research design and analysis. For the study, the researchers adapted six levels of influence to be able to fully promote healthy eating within schools and other factors that interact with it. The study similarly utilised the model to achieve a multilevel analysis in an effort to create a more extensive outcome with the different levels being interpreted against their relation to other levels.In the present study, the social ecological model plays a vital role in the creation of the research design as well as the analysis. The model, having a hierarchal but dynamic interaction in between levels will allow a full assessment of the possibilities built into the ‘Welcoming Cities’ initiative. Proponents of the initiative point to its broad global relevance given the significance of migration in contemporary times. The model can easily be fitted and adapted to both evaluation and problem solving and for this reason is highly useful for applied research. This framework supports inter-level interpretation and analysis of the data and its uses in developing policy to improve the initiative and customise it to the local setting.
