Abstract The United Nations Human Development Report (UNHDR) mentions that the rights of women and female children are inalienable, integral and indivisible. It further highlights the full and equal participation of women in every segment of the social process without any discrimination or without considering sex - gender hierarchies.1 The legal frameworks of the international system and local political space is accepting of the normative values of gender equality and the eradication of gender-based discrimination. But most of the majoritarian societies challenge these legal frameworks to address their political, social and market-oriented interests. These actions are driven by political, social and structural frameworks which have been accepted by the majoritarian societies in the liberal democratic world. Tamil women in upcountry tea plantations in Sri Lanka were subjected to systemic and structural violence because of Sinhala majoritarian statecrafts in post-independence Sri Lanka. The ethnocentric violence directly problematises human security, survival and the personal rights of the upcountry Tamil female labour force. This paper discusses the survival of Tamil female plantation labour forces, focusing mainly on the security crisis of female reproductive rights under the ethnocentric Sinhala Majoritarian Society.

Model Training

This paper reports a rapid identification method for a Chinese green tea with PGI, Anji-white tea, by class modeling techniques and NIR spectroscopy. 167 real and representative Anji-white tea samples were collected from 8 tea plantations in their original producing areas for model training. Another 81 non-Anji-white tea samples of similar appearance were collected from 7 important tea producing areas and used for validation of model specificity. Diffuse NIR spectra were measured with finely ground tea powders. OCPLS and SIMCA were used to describe the distribution of representative Anji-white tea objects and predict the authenticity of new objects. For data preprocessing, smoothing, derivatives, and SNV were applied to improve the raw spectra and classification performance. It is demonstrated that taking derivatives and SNV can improve classification accuracy and reduce the complexity of class models by removing spectral background and baseline. For the best models, the sensitivity and specificity were 0.886 and 0.951 for OCPLS, 0.886 and 0.938 for SIMCA with SNV spectra, respectively. Although it is difficult to perform an exhaustive analysis of all types of potential false objects, the proposed method can detect most of the important non-Anji-white teas in the Chinese market.

Proven Method

Tea leafhopper (Empoasca onukii Matsuda) is amongst the key pests in tea plantations around the East Asian region. Stereomicroscopy is a conventional method used for detecting tea leafhopper eggs by dissecting the tender tissues. However, there is a need for a faster and more efficient method to directly observe and investigate intact eggs within tea shoots. The absence of a proven method limits research efforts for determining the oviposition behavior of E. onukii. Herein, we applied the blue light detection method (BLDM), a technique recently developed for other species, in order to detect E. onukii eggs directly and non-destructively within the tender shoot. In addition, we compared BLDM against the traditional stereomicroscope detection method (SMDM) for four tea cultivars. Notably, our results revealed that BLDM was precise and effective in measuring the egg laying quantity of E. onukii on intact tea shoots. Neither tea cultivars nor egg density in the tender shoot significantly affected the accuracy of BLDM. Furthermore, biological characteristics that have rarely been reported previously for E. onukii were investigated using the BLDM, including zygote duration, ovipositional rhythm, egg distribution within the tender shoot, and in different leaf positions, numbers of eggs laid by a single female daily, and laid by the entire generation. Therefore, these findings provide insights into the basic and theoretical evidence for the strategy and mechanism associated with the oviposition behavior of E. onukii.
