Does political connection influence corporate financial decisions in unstable political environment?

The aim of this study is to examine the impact of political connection on the cost of debt, the cost of equity and the investment level in an unstable political environment. We use a sample of 55 Tunisian listed firms during the post-revolution period (2011–2018) and we apply a generalized least square (GLS) approach to test our hypotheses. Findings highlight that political connections increase the corporate financial costs and reduce the investment level. Furthermore, in an additional analysis, we show on the one hand that political instability negatively affects the investment and affects positively the cost of debt and the cost of equity. On the other hand, we make evidence that the political instability level negatively affects the relation between the political connection and the cost of debt. The contribution is, to the best of our knowledge, the absence of studies conducted in Tunisia countries examining the impact of political connection on the financial cost and investment level in an unstable political environment such as Tunisia.

重楼总皂苷对人胃癌MNK-45和MGC80-3细胞增殖的影响

目的 观察重楼总皂苷(Rhizoma paridis total saponins，RPTS)对人胃癌MNK 45和MGC80 3细胞增殖的影响。方法 设定5个不同浓度（5、10、20、40、80 μg/ml）RPTS处理两种细胞24、48、72 h后，采用四甲基偶氮唑蓝(methyl thiazolyl tetrazolium，MTT)法测定MNK 45细胞和MGC80 3细胞增殖抑制率；设定浓度为10 μg/ml处理两种细胞24 h，采用吖啶橙/溴化乙锭（acridine orange/ethidium bromide, AO/EB）双染观察细胞形态学变化；设定浓度为10、20 μg/ml处理两种细胞6 h，用流式细胞仪测定细胞周期。结果 5～80 μg/ml RPTS对MNK 45和MGC80 3细胞增殖均具有显著的抑制作用(P<0.05，或P<0.01)，且药物剂量越大、作用时间越长，其抑制作用越强（P<0.01）；在相同药物浓度及相同作用时间下，RPTS对MNN 45细胞增殖的抑制作用较对MGC80 3作用显著增强（P<0.01）；RPTS作用于两种细胞后荧光显微镜下观察均显示细胞凋亡特征；RPTS使MNK 45细胞增殖被阻滞于G0/G1期，使MGC80 3细胞增殖被阻滞于S期。结论 RPTS能抑制人胃癌MNK 45和MGC80 3细胞增殖，诱导两种肿瘤细胞凋亡，影响两种肿瘤细胞周期时相的分布，但对两种肿瘤细胞株的抑制作用和对细胞周期时相的影响存在差异。

紫外分光光度法测定醉鱼草果实中总三萜含量

目的 建立醉鱼草果实中总三萜的含量测定方法。方法 以齐墩果酸为对照品，用5%香草醛-冰醋酸溶液，高氯酸系统显色，在540 nm处测定样品吸光度。结果 齐墩果酸在2.45~24.50 μg/ml范围内吸光度与浓度呈良好的线性关系(A=0.059 4 c-0.037 9，r=0.999 8)，平均回收率为98.28%，相对标准偏差为1.59%（n=6），所测得醉鱼草果实中总三萜含量为4.13%。结论 该方法操作简便、快速，结果稳定，重现性好，适用于醉鱼草果实中总三萜含量的测定。     

Place and Policy Preferences – Spatial Divides in Attitudes towards Social Policies in Germany

The rise of the knowledge economy has led to a bifurcation between prosperous, often urban, areas and “left-behind” regions. While the literature has started to analyse the political implications of these developments for electoral behaviour and socio-cultural attitudes, the structuring of social policy preferences by place remains unclear. Distinguishing between an economic (booming-declining) and a geographic (urban–rural) dimension, I argue that differences in material self-interest and ideological predispositions explain spatial divides in support for different types of social policies. Combining original survey data on voters' preferences with municipal-level data in Germany, I show that general support for social policy is higher in declining than in booming regions. However, social investments (e.g., active labour market policies) are preferred over consumption policies (e.g., unemployment benefits) in booming and, to a smaller degree, in urban than in declining and rural regions. These findings contribute to a bigger discussion on compensating “left-behind” regions.
