This article argues that the 2015 xenophobic violence was allowed to spread due to persistent inaction by state officials. While the utterances of King Goodwill Zwelithini have in part fuelled the attacks, officials tend to perceive acts of xenophobia as ordinary crimes. This perception has resulted in ill-advised responses from the authorities, allowing this kind of hate crime against foreign nationals to engulf the whole country. In comparison with similar attacks in 2008, the violent spree in 2015 is characterised by a stronger surge in criminal activities. The militancy showcased fed a sense of insecurity amongst foreigners, creating a situation inconsistent with the country’s vaunted respect for human rights and the rule of law. Investors lost confidence in the country’s outlook, owing in part to determined denialism in government circles regarding the targeting of foreigners. While drawing from existing debates, the article’s principal objective is to critically examine the structural problems that enable xenophobia to proliferate and the (in)effectiveness of responses to the militancy involved in the 2015 attacks. Of particular interest are the suggested responses that could be effective in curbing future violence. The article concludes that xenophobia is systemic in post-apartheid South Africa. Strong cooperation between the government, national and international organisations could provide the basis for successful anti-xenophobia measures. The article further argues that the country is obliged to find a sustainable solution to the predicament for humanitarian reasons firstly, and in recognition of the support South Africans received from its African counterparts during the liberation struggle.

Infertility primarily refers to the biological inability of a person to contribute to conception. In women, it may also refer to the state when she is not able to carry a pregnancy to its full term. Female infertility is caused due to structural problems like blocked Fallopian tubes, defect in cervical canal, uterine fibroid or polyps. Hormonal imbalance leading .ovulation problems too can cause infertility. From Ayurvedic perspectives, Shukra Dhatu can get affected by various physical, mental causes and even by serious diseases. Poor quality Shukra Dhatu can cause infertility in males and females.

We revisited the effects of government bonds for the growth on the Nigerian capital market. Utilising time-series data obtained from the Nigeria Stock Exchange (NSE) annual reports for the period from 2010 to 2017, this study through the Generalised Method of Moments (GMM) regression estimator found that the value and the number of listed government bonds’ positively and significantly affect capital market growth in Nigeria. Furthermore, low capitalisation of government bonds negatively affects the growth of the market. The null hypothesis of the Hansen J-statistics is accepted; hence this implies that the IVs used in the GMM model is valid. We concluded that government bonds have positive and significant effects on the growth of the Nigerian capital market, thus government bonds have made the NSE All-Share Index grow over the period under investigation. Following the findings from the study, it was recommended, inter alia, that there should be more issuance of government bonds to the public and further to enhance the efficiency of the capital markets, both primary and secondary, while the funds raised from the capital market through government issuance should be channelled towards Nigeria’s productive sectors to promote an all-inclusive growth in the Nigerian economy.
