“监狱旅游”初探——以青岛德国监狱旧址博物馆为例

在现代社会里,人们对旅游差异化和体验化的高要求推动了旅游范围的扩大和旅游方式的多元化。在这种背景下,监狱作为一种旅游吸引物与目的地,正渐渐受到人们青睐。文章首先对监狱旅游进行分析,认为监狱文化是监狱旅游的核心内容,而监狱文化本身又包含司法文化、建筑文化、社会文化以及民族历史等多层次内容,结合青岛德国监狱旧址博物馆旅游开发的现状,提出监狱旅游应与同类旅游资源进行整合,形成合力,增加体验性设计,注重建筑景观协调等建议。     

Characterizing parameters of Jatropha curcas cell cultures for microgravity studies

Jatropha (Jatropha curcas) is a tropical perennial species identified as a potential biofuel crop. The oil is of excellent quality and it has been successfully tested as biodiesel and in jet fuel mixes. However, studies on breeding and genetic improvement of jatropha are limited. Space offers a unique environment for experiments aiming at the assessment of mutations and differential gene expression of crops and in vitro cultures of plants are convenient for studies of genetic variation as affected by microgravity. However, before microgravity studies can be successfully performed, pre-flight experiments are necessary to characterize plant material and validate flight hardware environmental conditions. Such preliminary studies set the ground for subsequent spaceflight experiments. The objectives of this study were to compare the in vitro growth of cultures from three explant sources (cotyledon, leaf, and stem sections) of three jatropha accessions (Brazil, India, and Tanzania) outside and inside the petriGAP, a modified group activation pack (GAP) flight hardware to fit petri dishes. In vitro jatropha cell cultures were established in petri dishes containing a modified MS medium and maintained in a plant growth chamber at 25 ± 2 °C in the dark. Parameters evaluated were surface area of the explant tissue (A), fresh weight (FW), and dry weight (DW) for a period of 12 weeks. Growth was observed for cultures from all accessions at week 12, including subsequent plantlet regeneration. For all accessions differences in A, FW and DW were observed for inside vs. outside the PetriGAPs. Growth parameters were affected by accession (genotype), explant type, and environment. The type of explant influenced the type of cell growth and subsequent plantlet regeneration capacity. However, overall cell growth showed no abnormalities. The present study demonstrated that jatropha in vitro cell cultures are suitable for growth inside PetriGAPs for a period of 12 weeks. The parameters evaluated in this study provide the basic ground work and pre-flight assessment needed to justify a model for microgravity studies with jatropha in vitro cell cultures. Future studies should focus on results of experiments performed with jatropha in vitro cultures in microgravity.

Modelling the effects of microgravity on the permeability of air interface respiratory epithelial cell layers

Although it has been suggested that microgravity might affect drug absorption in vivo, drug permeability across epithelial barriers has not yet been investigated in vitro during modelled microgravity. Therefore, a cell culture/diffusion chamber was designed specifically to accommodate epithelial cell layers in a 3D-clinostat and allow epithelial permeability to be measured under microgravity conditions in vitro with minimum alteration to established cell culture techniques. Human respiratory epithelial Calu-3 cell layers were used to model the airway epithelium. Cells grown at an air interface in the diffusion chamber from day 1 or day 5 after seeding on 24-well polyester Transwell cell culture inserts developed a similar transepithelial electrical resistance (TER) to cells cultured in conventional cell culture plates. Confluent Calu-3 layers exposed to modelled microgravity in the 3D-clinostat for up to 48 h maintained their high TER. The permeability of the paracellular marker ¹⁴C-mannitol was unaffected after a 24 h rotation of the cell layers in the 3D-clinostat, but was increased 2-fold after 48 h of modelled microgravity. It was demonstrated that the culture/diffusion chamber developed is suitable for culturing epithelial cell layers and, when subjected to rotation in the 3D-clinostat, will be a valuable in vitro system in which to study the influence of microgravity on epithelial permeability and drug transport.

我国农村社区公共文化的缺失与重建

目前我国农村社区的公共文化建设不容乐观，公共文化在农村的“缺场”现象普遍，农民主体性意识缺乏，农村社区公共文化生活在整个农村生活中日渐式微。农村社区的公共文化建设，不仅仅是政府给予什么的问题，重要的是让农民自己动起来。只有充分发挥广大农民作为主体的积极性，让农民真正参与到社区公共文化建设的实践中来，改变农民的“原子化”状态，才能建设出适合各地农民不同需求的农村社区公共文化。
