Changes in Sexual Distress,Depression and Sexual Function after Clitoral Reconstruction in Women with Female Genital Mutilation/Cutting

Abstract

Background: Female genital mutilation/cutting (FGM/C) links health complications and psychological distress. However, there is scarce literature on how women with FGM/C respond to treatment interventions. Objective: In this study, we aimed to assess changes in depression symptomatology, sexual function, and distress following clitoral reconstructive surgery combined with a psychoeducational intervention. Methods: The reconstructive surgery consisted of recovering the remaining clitoris and placing it externally and as close to the vagina as possible. FGM/C patients (n?=?27) received psychological support and sexual counseling upon undergoing the surgical intervention and were further assessed at 6-month follow-up. Moreover, they completed the Beck Depression Inventory and the Female Sexual Distress Scale Revised at these two time points. Patients’ sexual dysfunction was assessed according to DSM-5 criteria. Results: Statistically significant clinical changes after FGM/C were reported. Overall, patients presented reduced depression and sexual distress levels, and decreased female sexual interest/arousal disorder prevalence. Results also revealed that sexual distress improvements were more significant in Type I FGM/C patients. Conclusions: Significant improvements in sexual distress, psychopathology, and sexual function were observed in our sample following reconstructive surgery, suggesting that combined interventions are effective for treatment.     

论“断水、断电”作为行政强制执行方式的正当性

＂断水、断电＂是督促当事人履行义务的有效手段,能在当前水污染防治中发挥重要作用。对目前已有规范进行分析后发现,它对若干基本权利构成限制,与最小侵害原则不符。然最小侵害仅为比例原则组成部分,乃警察法时代控权理念的产物。时代背景变迁后,它已不再单独具有评判管制措施合法性的功能。＂断水、断电＂作为一种行政强制执行方式,至少在我国当前的水污染治理领域中具有正当性。

Organizational learning in SMEs’ internationalization: A moderated mediating effect of absorptive capacity

We examine both mediation and moderation effects on the direct relationship between internationalization speed and firm performance in the context of small and medium-sized enterprises (SMEs). Building on prior studies that focus either on the direct speed–performance linkage or the moderating role played by knowledge, we suggest that an important source of performance variations is organizational learning. Grounded in the organizational learning perspective, we argue that firm strategies regarding speed and earliness of internationalization provide the SMEs with opportunities to develop their absorptive capacity, and thus enhance their performance. Using survey data from 343 SMEs in Australia and New Zealand, our empirical results suggest that absorptive capacity is associated with internationalization speed in a reversed U-shape relationship and that in turn absorptive capacity mediates the direct speed–performance relationship. Moreover, this mediating effect is moderated by earliness of internationalization. By demonstrating the moderated mediating effect of absorptive capacity as a novel mechanism to achieving superior performance, we enhance the understanding of how firms succeed internationally.     

绝缘与有情化——再论丰子恺文艺观

绝缘和有情化这两个看似对立的观点,在丰子恺的文艺创作中得到了很好的融合统一。丰子恺借“绝缘”斩断了事物的实用性、功利性,得以直视其本真的意义,聚精会神地欣赏事物本身的“关”。“有情化”又使他化世间无情为有情,让内心充满了不尽的生机。不论什么样的艰难环境下,都可以坚守自己的理念和独立的人格,较少地受到外界环境的干扰,在对生活始终充满热爱的同时,保持着无尽的创作动力。
