基于迁移学习的家猪图像识别研究

为实现家猪图像识别并提高识别准确率,提出一种基于迁移学习的家猪图像识别方法。首先对现有数据集进行数据增强,然后迁移 VGG16 模型并对其进行微调,从而更好地提取图像特征并缩短网络训练时间。采用自归一化神经网络解决了梯度消失和梯度爆炸问题,在网络构造时使用全局平均池化代替全连接层,以达到降低模型过拟合的效果。实验对比结果表明,该方法分类效果较好,准确率达到了 84%,召回率和 F1 值分别提升至 0.8、0.82,各项指标相比基础模型均有所提升。     

Extending the Possibilities of Multicultural Community Partnerships in Urban Public Schools

To combat the sociocultural tensions that the city of Changeton is facing, an effort is being made by the school district to create a systemwide multicultural education program. A volunteer group has been established to shape what it hopes will provide a foundation for working toward mitigating the cultural strife that plagues the schools and community. Through a 3-year qualitative study, this research has documented the developments in the committee's work. The specific area addressed here is the group's efforts to create a partnership between the school and the community. This article provides practical ideas to urban educators interested in such an endeavor and shows that the critical problem is that parental involvement is often not recognized as being determined within specific and unequal relations of power—that attempts at school/community partnerships are often based on white, middle-class assumptions about parents' outlooks, language, resources, and time available for schoolwork. The focus and intent here are to acknowledge that it is crucial to recognize the multiplicity of groups and issues that are present in every town and city. Without being open to all differences of opinion andperspective, the idea of community involvement and public deliberation is fruitless.

Training program in child abuse for community health workers

A wide range of health workers in the community provide care for families that abuse or have a potential for abusing their children. Frequently these workers are unable to work effectively because of difficulty dealing with feelings aroused by contact with such families.An experimental child abuse training program for community health workers was designed by a pediatrician, a social worker, a public health nurse and two child psychiatrists. This program included a six-month study group which met weekly to focus on feelings and conflcts aroused during the course of work with abusing or potentially abusing families.Through analysis of the group experience, the leaders identified eleven sets of feelings or conflicts which seemed to interfere consistently with effective delivery of care: 1)anxieties about a) being physically harmed by angry parents and b) about the effects of a decision; 2) denial and inhibition of anger; 3) need for emotional gratification from clients; 4) lack of professional support; 5) feelings of incompetence; 6) denial and projection of responsbility; 7) feeling total responsibility for assigned families; 8) difficulty separating personal from professional responsibility; 9) feelings of being a victim; 10) ambivalent feelings a) toward clients and b) about one's professional role; 11) need to be in control.This type of group experience seems to be an effective method for exploration and resolution of feelings and conflicts.

解析弱势群体亲子关系存在的问题

当今,亲子关系存在着一些问题,成为孩子成长过程中的隐忧,由此出现了一系列连锁性不良反应.而这种现象在弱势群体中表现的尤为突出.主要表现在弱势群体亲子间互动的内容狭窄、方式简单,互动频率偏低,还有就是因价值取向偏离而引起的特定期望值过高及亲子地位的对立.这些问题是错综复杂地交织在一起的,本文仅从社会学的视角来解析弱势群体亲子关系存在的问题,希望能对我们促进弱势群体亲子互动,改善其亲子关系有所启发和指导.

Knowledge Capabilities of Local Government in the Context of Decentralisation in Ukraine

Abstract

There is an increasing actualisation of the knowledge component of the institutional capacity of local self-government authorities in Ukraine within ongoing decentralisation. The issue that arises concerns the officials’ knowledge sufficiency to generate and implement new ideas on the territories’ development, and the availability of unique skills for the development of relevant programmes, projects and plans. Herein, the analysis of the real knowledge needs of officials, whose sphere of competence lies in decision-making about the territories’ ways of development as well as their practical implementation, plays an important role. The article presents the results of a study of the opinions of local self-government officials of united territorial communities (UTCs) from the Dnipropetrovsk, Sumy, Zhytomyr, Kherson and Poltava regions of Ukraine, concerning their level of knowledge on the territories’ management; their needs for additional knowledge; the most common and convenient ways of obtaining knowledge; and the most problematic areas where the new knowledge is most demanded. The obtained data and the conclusions drawn can be considered, in particular, as an informational basis for the formation of training programmes and plans, cases and tasks for specialists training in the field of public administration.
