This article offers insights into the organization of Scioto Hopewell craft production and examines the implications of this organization through the lens of ritual economy. We present a novel analysis of investigations at the North 40 site, concluding that it is a craft production site located on the outskirts of the renowned Mound City Group. High-resolution landscape-scale magnetic survey revealed a cluster of three large structures and two rows of associated pits; one of the buildings and three of the pits were sampled in excavations. Evidence from the North 40 site marks this as the best-documented Scioto Hopewell craft production site. Mica, chert, and copper were crafted here in contexts organized outside the realm of domestic household production and consumption. Other material remains from the site suggest that crafting was specialized and embedded in ceremonial contexts. This analysis of the complex organization of Scioto Hopewell craft production provides grounds for further understanding the elaborate ceremonialism practiced by Middle Woodland (AD 1–400) societies and adds to the known complexity of craft production in small-scale societies. Furthermore, this article contributes to a growing body of literature demonstrating the utility of ritual economy as a framework for approaching the sociality of small-scale societies.

This article aims to promote the high-quality development of the Great Changsha-Zhuzhou-Xiangtan City Group and improve the green innovation efficiency of urban agglomeration. This article takes green innovation in networked urban agglomerations as its research subject. Furthermore, it analyzes the impact of network structure characteristics such as network scale and network structure hole on green innovation in urban agglomerations. Moreover, this study uses the unexpected output SBM model to measure green innovation efficiency of the eight prefecture-level cities in the Great Changsha-Zhuzhou-Xiangtan City Group from 2012 to 2018 and analyzes its influencing factors using the panel Tobit model. The results show that the overall green innovation efficiency of the Great Changsha-Zhuzhou-Xiangtan City Group is stable. The distribution of urban green innovation efficiency in the region is characterized by urban gradient and mid-stream drive. In the process of networked innovation, economic development, which has a positive impact on green innovation, promotes the overall effectiveness of the network structure. The low efficiency of urban educational resources, which has a negative impact on green innovation, leads to the redundancy of a network scale. The unapparent advantage of industrial structures, which have a negative impact on the development of green innovation, leads to the insufficient depth and breadth of network openness. Lastly, government support and the level of infrastructure have no impact on green innovation.

ABSTRACTThis research is motivated by difficulties in fine motor skills, problems that occur in group A in Kindergarten IP Assalaam Tasikmalaya City, there are still many children who are less in fine motor development especially in motion skills of both hands, fingers and skill to coordinate the speed or dexterity of hands with eye movements. This is suspected because the learning in the classroom is still monotonous and the teacher still has not used the media, especially for the fine motor development. The purpose of this research is improve the fine motor skills of children through Balok Bergambar media in group A age 4-5 year in kindergarten IP Assalaam City Tasikmalaya. Classroom Action Research (PTK) conducted in collaboration with teachers, implemented 3 cycles using the Kemmis and MC Taggart Model. The subjects of the research were children of A kindergarten IP Assalaam Tasikmalaya City group consisting of 18 people, as many as eight male and 10 female and one teacher as a partner teacher. The object of research is the fine motor ability of the child through Balok Bergambar media. Data collection techniques used observation and documentation, while data analysis techniques using descriptive qualitative. Each cycle consisting of four and stages: planning, implementation stage, observation stage, and reflection stage. The results of the research have shown that the use of Balok Bergambar media can improve the fine motor ability of the child. This is evidenced by the increase in the ability of teachers in planning daily learning, the ability of teachers in the process of implementation of learning by using Balok Bergambar media and the ability to fine motor children aged 4-5 years from each cycle. Can be concluded the Balok Bergambar media can improve the fine motor ability of children aged 4-5 years in kindergarten IP Assalaam Tasikmalaya City. ABSTRAKPenelitian ini dilatarbelakangi adanya kesulitan dalam kemampuan motorik halus, permasalahan yang terjadi pada kelompok A di TK IP Assalaam Kota Tasikmalaya, masih banyak anak yang kurang dalam perkembangan motorik halusnya khususnya dalam keterampilan gerak kedua tangan, keterampilan jari jemari dan keterampilan mengkoordinasikan kecepatan atau kecekatan tangan dengan gerakan mata. Hal ini diduga disebabkan karena pembelajaran di kelas masih monoton dan guru masih belum menggunakan media, khususnya untuk perkembangan motorik halusnya. Tujuan penelitian ini adalah untuk meningkatkan kemampuan motorik halus anak melalui media balok bergambar pada kelompok A usia 4-5 tahun di TKIP Assalaam Kota Tasikmalaya. Penelitian Tindakan Kelas (PTK) yang dilakukan bekerjasama dengan guru, dilaksanakan sebanyak 3 siklus dengan menggunakan model Kemmis dan Mc. Taggart. Subjek penelitian adalah anak kelompok A TKIP Assalaam Kota Tasikmalaya yang terdiri dari 18 orang yaitu sebanyak  delapan orang laki-laki dan 10 orang perempuan dan  satu orang guru sebagai guru mitra.  Objek penelitian adalah kemampuan motorik halus anak melalui media balok bergambar. Teknik pengumpulan data menggunakan observasi dan dokmentasi, sedangkan teknik analisis data menggunakan deskriptif  kualitatif. Setiap siklus terdiri dari empat tahap yaitu perencanaan, tahap pelaksanaan, tahap observasi, dan tahap refleksi. Hasil penelitian yang telah dilaksanakan menunjukkan bahwa penggunaan media balok bergambar dapat meningkatkan kemampuan motorik halus anak. Hal ini dibuktikan dengan adanya peningkatan kemampuan guru dalam  merencanakan pembelajaran harian, kemampuan guru dalam proses pelaksanaan pembelajaran dengan menggunakan media balok bergambar dan kemampuan motork halus anak usia 4-5 tahun dari setiap siklusnya. Maka dapat disimpulkan media balok bergambar dapat meningkatkan kemampuan motorik halus anak usia 4-5 tahun di TKIP Assalaam Kota Tasikmalaya.

City group refers to a collection of cities. Through the development and growth, and these cities form a chain of metropolitan areas. In a city group, cities are divided into central cities and subordinate cities. Generally, central cities have greater chances to develop. However, subordinate cities may not have great chances to develop unless they are adjacent to central cities. Thus, a city is more likely to develop well if it is near a central city. In the process, the spatial distribution of cities changes all the time. Urbanologists call the above phenomena as the evolution of city groups. In this paper, the city group optimization algorithm is presented, which is based on urbanology and mimics the evolution of city groups. The robustness and evolutionary process of the proposed city group optimization algorithm are validated by testing it on 15 benchmark functions. The comparative results show that the proposed algorithm is effective for solving complexly continuous problems due to a stronger ability to escape from local optima.
