近年来,监狱、未成年犯管教所等机构对管理专业人才的需求日益增长,但是目前各省监狱系统、未成年犯管教所等机构的人员招录条件中大部分岗位的“学历要求”都明确表明“大学本科”,如此一来,实现高职与本科监狱学教育的衔接贯通、探索人才联合培养机制愈发重要。当前,专科层次刑事执行专业学生在就业市场中面临学历门槛,而开设本科监狱学的学校则相对较少,且难以实现直接对接专科层次的学生。因此,聚焦于解决当前监狱学领域专科层次学生学历提升受限、人才流失等问题,探索高职与本科监狱学衔接贯通的人才联合培养机制,构建专本有效衔接的人才培养模式和课程体系,实现学历层次、课程内容、师资队伍及实习实训的全面衔接,对于培养具有更专业监狱业务能力的人民警察,提升监狱系统整体人才素质具有重要意义。

选取2017年中国地区投入产出表和2021年相关数据构建SAM表,刻画绿色信贷政策的传导路径,评估绿色信贷政策对企业创新的影响。研究发现:绿色信贷政策对抑制目标行业的投资行为较为有效,并在短期、中期内能减少造纸业、化工行业产出;从长期来看,目标行业投资、产出回升将抵消绿色信贷对抑制目标行业产出的效果。这表明在研究绿色信贷政策与企业绿色创新活动的关系时,应重视偏向性技术创新的作用,并动态追踪绿色信贷在短期、中期、长期的作用效果。

人工湿地是生态修复受污染水体的重要手段,对氮的去除效果显著,但不同植物湿地对氮去除效果差异明显,因此不同类型植物组合后的湿地对氮去除效果及去除途径值得进一步研究。通过室内控制试验,以常见浮水植物绿狐尾藻(Myriophyllum elatinoides)和挺水植物梭鱼草(Pontederia cordata)为研究对象,利用^(15)N稳定同位素示踪技术探究绿狐尾藻、梭鱼草及绿狐尾藻+梭鱼草植物组合对氨氮(NH_(4)^(+)-N)的去除途径。结果表明,绿狐尾藻+梭鱼草植物组合处理相较于单一绿狐尾藻和梭鱼草处理对氮的脱除量分别提高1.8%和3.6%。基于^(15)N质量平衡,绿狐尾藻、梭鱼草和绿狐尾藻+梭鱼草植物组合处理氮去除途径的底泥吸附贡献分别为8.30%、7.96%和6.94%,植物吸收贡献分别为41.76%、35.34%和48.67%,微生物作用去除贡献分别为49.94%、56.71%和44.39%。微生物作用在湿地脱氮过程中占主导地位。相较于单一植物湿地,植物组合湿地对氮的去除效果得到提升,同时促进了植物对水体NH 4+-N的吸收。该研究有助于更好地理解植物组合湿地对氨氮的脱除途径。

Study on soil phosphorus（P） fraction is an important aspect in probing the mechanisms of soil P accumulation in farmland and mitigating its losing risk to the environment. We used a sequential extraction method to evaluate the impacts of long-term fertilization and straw incorporation on inorganic, organic, and residual P（Pi, Po, and Pre） fractions in the plow layer（0–20 cm） of acidic paddy soil in southern China. The experiment comprised of six treatments：（i） no fertilizer control（CK）;（ii） straw incorporation and green manure（SG）;（iii） nitrogen and P fertilizer（NP）;（iv） NP＋SG;（v） NP＋K fertilizer（NPK）; and（vi） NPK＋SG. The results showed that, compared to the initial total soil P content（TSP, 600 mg kg^–1 in 1990）, long-term（20 years） combined continuous P fertilizer and SG significantly increased P accumulation（by 13–20%） while single fertilization（39.3 kg P ha^–1 yr^–1） could maintain soil P status at the most. The average soil P fractions comprised of extractable Pi, Po, and Pre by 51.7, 33.4, and 14.9% in total soil P, respectively. With comparison of no fertilizer addition（CK）, long-term single fertilization significantly（P〈0.05） increased the accumulation of Na HCO3^–, Na OH^–, and HCl^– extractable Pi fractions accounting for two- to three-fold, while SG increased the accumulation of Na HCO3^– and Na OH^– extractable Piand Po accounting for 12–60%. Though the mobilization of Pre fractions was not significant（P〉0.05）, our data indicate that SG may partially substitute for fertilizer P input and minimizing soil P accumulation and subsequent environmental risk in the subtropical paddy soil.

Strength and deformability characteristics of rock with pre-existing fissures are governed by cracking behavior. To further research the effects of pre-existing fissures on the mechanical properties and crack coalescence process, a series of uniaxial compression tests were carried out for rock-like material with two unparallel *** the present study, cement, quartz sand, and water were used to fabricate a kind of brittle rock-like material cylindrical model specimen. The mechanical properties of rock-like material specimen used in this research were all in good agreement with the brittle rock materials. Two unparallel fissures（a horizontal fissure and an inclined fissure） were created by inserting steel during molding the model *** all the pre-fissured rock-like specimens were tested under uniaxial compression by a rock mechanics servocontrolled testing system. The peak strength and Young＇s modulus of pre-fissured specimen all first decreased and then increased when the fissure angle increased from 0？to 75？.In order to investigate the crack initiation, propagation and coalescence process, photographic monitoring was adopted to capture images during the entire deformation ***, acoustic emission（AE） monitoring technique was also used to obtain the AE evolution characteristic of prefissured specimen. The relationship between axial stress, AE events, and the crack coalescence process was set up： when a new crack was initiated or a crack coalescence occurred, thecorresponding axial stress dropped in the axial stress–time curve and a big AE event could be observed ***, the mechanism of crack propagation under microscopic observation was discussed. These experimental results are expected to increase the understanding of the strength failure behavior and the cracking mechanism of rock containing unparallel fissures.

AIM： To determine the association between retinal vasculature changes and ***： MEDliNE and EMBASE were searched for relevant human studies to September 2015 that investigated the association between retinal vasculature changes and the prevalence or incidence of stroke; the studies were independently examined for their qualities. Data on clinical characteristics and calculated summary odds ratios （ORs） were extracted for associations between retinal microvascular abnormalities and stroke, including stroke subtypes where possible, and adjusted for key variables. RESULTS： Nine cases were included in the study comprising 20 659 patients, 1178 of whom were stroke patients. The retinal microvascular morphological markers used were hemorrhage, microaneurysm, vessel caliber, arteriovenous nicking, and fractal dimension. OR of retinal arteriole narrowing and retinal arteriovenous nicking and stroke was 1.42 and 1.91, respectively, indicating that a small-caliber retinal arteriole and retinal arteriovenous nicking were associated with stroke. OR of retinal hemorrhage and retinal microaneurysm and stroke was 3.21 and 3.83, respectively, indicating that retinal microvascular lesions were highly associated with stroke. Results also showed that retinal fractal dimension reduction was associated with stroke （OR： 2.28 for arteriole network, OR： 1.80 for venular network）.CONCLUSION： Retinal vasculature changes have a specific relationship to stroke, which is promising evidence for the prediction of stroke using computerized retinal vessel analysis.
