Western feminist consciousness in Buchi Emecheta's The joys of motherhood
Feminism is a collection of movements which struggles for women's rights. Focusing on gender as a basis of women's sexual oppression, feminist scholarship attempts to establish equal rights for women politically, economically, socially, personally, etc. The Joys of Motherhood highlights Buchi Emecheta's critical view toward colonialism and racism affecting Third world women's lives. Besides this, Emecheta goes further to display African women's invisibility and marginalization-which were out of sight for a long time-in terms of some aspects of Western feminist discourse. Her creative discourse, in this regard, casts further light upon the issue of gender oppression in African feminist study. Hence, this study attempts to examine the way in which Emecheta furthers Western feminist ideology
Margaret Atwood in the second and third waves of feminism on the basis of Julia Kristeva's theories
Although Margaret Atwood started writing in the second phase of feminism, some of her works show the features of the second and the third wave of feminism. It's clear in Atwood’s Cat’s Eye. Elaine, protagonist of the novel, and other female characters indicate these features. Some of Atwood’s works imply Kristeva's theories. Unlike the second wave of feminism, Julia Kristeva as a postmodern feminist rejects the distinction between sex and gender believing that these two terms respectively represent biology and culture which cannot be separated from each other. This idea can be examined in Margaret Atwood's novel, Cat's Eye, as a feature of the third wave of feminism. The authors of this article seek to analyze Atwood's famous novel, Cat's Eye, in the second and third waves of feminism based on Julia Kristeva's theories
A Study of Buchi Emecheta’s The Joys of Motherhood in the Light of Chandra Talpade Mohanty: A Postcolonial Feminist Theory
Mohanty is a prominent contemporary postcolonial feminist who demands women’s solidarity based on the common context of struggle against the hierarchical powers- colonialism, capitalism, racism and patriarchy. This study seeks to examine traces of colonialism, capitalism, racism and solidarity in Emecheta’s The Joys of Motherhood according to Mohanty’s postcolonial feminist theory

Malignant Transformation in Leukoplakia and Its Associated Factors in Southern Iran: A Hospital Based Experience
We evaluated factors that affect malignant transformation of leukoplakia in a sample of the Iranian population.
Methods: The records of patients with a clinical diagnosis of leukoplakia during a 20-year period from 1989-2009 referred to two of the largest referral centers in southern Iran were studied. Patients that developed malignant trans-formation were compared with patients that did not have malignant changes.
Results: Of 522 patients, female patients, those over 50 yr old and with lesions located on the tongue had the highest rate of malignant changes. Female patients with malignant changes were mostly non-smokers (76.4%), while male pa-tients with malignant changes were mostly smokers (63.8% in non-smokers) (P<0.001). In our univariate analysis, male sex and smoking showed lower chances for malignant transformation (OR: 0.57; CI=0.397-0.822 and OR: 0.025; CI=0.141-0.299, respectively), while age above 50 was a risk factor for malignant transformation (OR: 3.57; CI=2.32-5.42). In the multivariate analysis, smoking (OR: 0.317; 95% CI=0.16–0.626) and morphological presentation as eryt-hroplakia (OR: 0.025; 95% CI=0.005-0.131) had low chances for developing malignant changes, while site of lesion on the tongue (OR: 774; 95% CI=60-9838) and morphological presentation as erythroleukoplakia (OR: 6.26; 95% CI=3.16-12.38) were a risk factor for developing malignant changes
Conclusion: A follow-up program and further work-up should be considered for Iranian patients who have a leukop-lakia lesion that is flat and are white patch or plaques with red components, in addition for patients who have lesions located on the tongue and for nonsmokers who develops leukoplakia lesions
Improving robotic hand control via adaptive Fuzzy-PI controller using classification of EMG signals
Robotic or prosthetic organs are designed to have the maximum similarity to human organs. This paper aims to improve robotic hand control via an adaptive Fuzzy-PI controller using EMG signals. The data is collected from the FDS and FPL muscles of the forearm of five individuals who performed eight movements. Then, appropriate filters are used to eliminate the noise of the signals, and MAV, VAR, and SE features are extracted. Based on MAV and VAR, classification is carried out using DA, KNN, and SVM. With an average accuracy, specificity, and sensitivity of 90.69%, 94.64%, and 62.10%, SVM is a better choice for movement detection. Following the movement detection by SVM, an appropriate reference signal is sent to the controller. The reference signal is the angle change of the fingers during the movement. All the eight gestures are modeled in a new way through these angles. The adaptive fuzzy-PI controller is used to control a robotic hand model with fifteen degrees of freedom. It has the advantages of learning from human experiences and adapting to environmental changes. The performance of the controller is evaluated in two ways. One is the comparison of the fuzzy-PI with the PI by RMSE. The average RMSE for eight movements using the fuzzy-PI is 1.6067, and for the PI, 5.0082. These results show that the fuzzy-PI controller performs better than the PI. Another new evaluation way presented in this paper is comparing the EMG signal features with the robotic hand movement signal features in terms of RMSE. The small RMSE values indicate that the EMG signal and robotic hand movement data features are significantly similar. Therefore, it can be concluded that the robotic hand controlled by the proposed controller is notably identical to the human hand
