Magister Psychologiae - MPsych / A concentration about issues important to the subpopulation of children in conflict with the law has received much more attention over the past few years. It is a known fact that within all male environments the likelihood of violence and especially sexual violence is exponential. Male on male rape as a topic has only received greater exposure over the last decade. Male on male rape within the context of the child and youth care context has however been reported, recorded and written about in academia to a far lesser degree.Within this research study it was found that within the child and youth care context oppressive practices of male on male rape and exploitation were rife. Life is marred by intra-personal, inter-personal and institutional violence. A hierarchy based on the ability to resort to violence and gender mitigated all experiences within this context.Through these experiences children came to understand the phenomenon of male on male rape.This research study was exploratory in nature and aimed to gain a deeper understanding of how children within this context understood and spoke about male on male rape.This endeavour was qualitative in approach and utilised social constructionism and the theory of oppression to understand the discourses produced by participants. The participants were males with age ranging from 16 to 18 years. An interview was the framework within which the phenomenon of male on male rape was discusses. The information gained from participants was managed through the use of discourse analysis. The highest ethical standards were upheld during the research process.In conclusion three main discourses were utilised by participants to make sense of the phenomenon of male on male rape. These discourses were the discourse of violence,the discourse of gang culture and the discourse of gender. These discourses intersected and predominantly functioned to hinder the reporting and likelihood of children that were sexually assaulted acquiring assistance.

Cocaine- and amphetamine-regulated transcript (CART) is a novel family of peptides, of which CART peptide fragments 55-102 and 62-102 are reported to be the endogenous, physiologically active peptides. Immunohistochemical studies with an antiserum directed against the CART peptide fragment 55-102 revealed CART-like immunoreactive (CART-LI) nerve fibers in the rat epididymis. The number was highest in the cauda epididymis and became progressively fewer toward the caput epididymis; the vas deferens exhibited an abundance of CART-LI fibers. Injection of the retrograde tracer Fluorogold (Fluorochrome, Inc., Englewood, CO) to the junction between the vas deferens and cauda epididymis labeled a large number of neurons in the major pelvic ganglion, some of which were CART-positive. Double-labeling the ganglion sections with tyrosine hydroxylase (TH) and CART antisera revealed that CART-LI and TH-LI were expressed in two distinct populations of ganglion cells. Some of the TH-LI cells in the ganglia, however, were covered with web-like CART-LI endings. The effects of CART peptide 55-102, referred to herein as CART, on anion secretion in the form of short circuit currents (Isc) were assessed in cultured epithelia. The CART (1 to 5 μM) applied to the basolateral or apical side of the cultured epithelia caused no significant responses on Isc, whereas lys-bradykinin (1 μM) produced a large Isc response in the same preparations. Our results show that CART-LI is present in a population of rat pelvic ganglion cells, which may give rise to CART-LI nerve fibers as observed in the vas deferens and the epididymis. The biological function of CART in the rat epididymis is not known, but it apparently is not involved in ion secretion across the epithelium.

>Magister Scientiae - MSc / Bladder grasshoppers belong to the order Orthoptera, ancient family Pneumoridae and Superfamily Pneumoroidea. This small group of grasshoppers are sound producing, nocturnal, herbivorous grasshoppers endemic to the coastal regions of southern Africa. Very little genetic work has been done on these grasshoppers, and there is some taxonomic confusion regarding the validity of some species descriptions. The aim of this study was to provide much needed clarity on the true taxonomic diversity and polymorphic attributes within the Pneumoridae, focusing on selected taxa of uncertain status. Bladder grasshoppers show distinct discontinuous polymorphism, resulting in two clearly different male morphs utilizing two different mating strategies. Primary males make use of acoustic communication for mate location. Secondary males (alternate males) are significantly smaller and employ a “sneaker” or satellite strategy where they exploit the calling between duetting couples to locate the females before the primary male. Three species of bladder grasshoppers have been described (Parabullacris vansoni, Paraphysemacris spinosus and Pneumoracris browni) that only have an alternate male morph. The validity of these species descriptions has come into question with the discovery of alternate male morphs in at least three other species (Bullacris discolor, B. membracioides and B. obliqua). Thus, the species described by Dirsh (1963) may simply be alternate males of existing species. However, to date there have been no studies looking at the genetics of alternate males, which would definitively establish whether they are conspecific with primary males.

The labour market in Sweden is highly gender segregated. One of the sectors where this is visible is within the forestry sector, whereas of 2020, only 11 percent of the working force were female. Research has shown that in male dominated sectors, male domination is upheld through organizational structures, norms, processes, and relations. In these sectors, women are controlled and subordinated by various means. In the Swedish forestry industry, women established a non-male network after their Me Too hashtag #slutavverkat as a way to keep the focus on the question of gendered structures. This study examines how women experience working in the Swedish forestry sector and how a network for non-males influences this experience. A phenomenological approach inspired the study. The data consists of 10 interviews with women, working or who have recently worked, in the forestry industry and all members of the non-male network. The theoretical framework consists of Acker (2012) and Ahmed (2006), which unfold a deeper sociological understanding of gendered structures and belonging, passing and non-passing in organizational spaces. The results show that women experience belonging due to the shared interest in the forestry sector but need to relate to the male dominance of the sector in different ways. Moreover, women experience problems to pass without being stopped or questioned and need to manage situations individually due to the male dominating processes in the sector. By participating in a non-male network women can negotiate the female body and reframe their experiences, making them feel more accepted in the sector and less alone.
