title: Exploring the role that language plays in solving mathematical word problems for the Solomon Islands secondary school students

authors: Ambrose, Malefoasi

subjects: mathematical word problems

abstract: Mathematics is described as language. There is a strong link between mathematics and English language. This study is concerned with the role of language factors and proficiency of students in comprehension and solving of word problems in the Solomon Islands. In particular, it explores the impact of language on the comprehension and solving of word problems for year eight students in three secondary schools in Honiara. Research data was gathered using mixed-method approach of data collection. The data collection happened in two phases. Firstly language and mathematical assessment portfolios were put together for 45 participants. Secondly, a semi-structured recall interview was conducted on eight participants chosen from the 45. The data gathering was conducted in the Solomon Islands in September 2009. There are interesting findings revealed in this research. In the language and mathematics baseline assessment portfolios, the scatter diagram showed no strong correlation between vocabulary knowledge and word problem solving. However, evidence from the word problems exercise and semi-structured recall interview elicited vocabulary and syntactical features as the main factors causing difficulties in word problems solving for the secondary school of the Solomon Islands students. Context and conceptual understanding played a role in facilitating the understanding of word problems. Some students demonstrated abilities contributing to their achievement in mathematics and language. However, further studies need to be done in relation to this area as it is very important and has implications for pedagogy, curriculum and learning improvement for teachers and students.

title: Investigating stratigraphic evidence for Antarctic glaciation in the greenhouse world of the Paleocene, eastern North Island, New Zealand

authors: Tayler, Michael James Stewart

subjects: Paleocene

abstract: Early Paleogene (Paleocene-Eocene) climate was significantly warmer than today, with the poles generally considered to have been free of ice. These greenhouse conditions ended in the earliest Oligocene when the formation of the circum-Antarctic seaway between Antarctica and Australia had widened sufficiently to allow thermal isolation of the Antarctic continent and expansion of ice sheets to sea level. The associated invigorated Southern Ocean circulation patterns have been deemed responsible for formation of the Marshall Unconformity (32-29 Ma), a prominent hiatus in many Early Oligocene sedimentary sections in the wider New Zealand region. However, some recent studies have suggested there may have been short periods of significant Antarctic glaciation prior to opening of the circum-Antarctic seaway, including in the Late Paleocene at c. 58-57 Ma, referred to in this study as the “Late Paleocene event” (LPE). This study investigates the origin(s) of sedimentary sequences from four eastern North Island early Paleogene sections with the aim of determining whether any links can be made between the nature of the sediment facies and their bounding contacts with ice sheet growth on Antarctica. A late Paleogene section that records a possible occurrence of the Early Oligocene Marshall Unconformity has also been studied with the aim of comparing lithologic features from the site with those in the early Paleogene study sections. Methods used include detailed logging and description of sedimentary strata, and petrographic, mineralogical, grain size, elemental, stable carbon and oxygen isotope, organic carbon content, micropaleontologic, and palynofacies analyses. In the study sections the LPE is represented by dark grey, brown-grey, or black, occasionally glauconitic, non-calcareous mudstone, often with relatively high organic matter contents. Geochemical proxies indicate that during deposition of these lithologies siliceous microbiota were the dominant primary producers in the overlying surface ocean waters, suggesting a period of cooling and enhanced upwelling occurred at the time. Additionally, relative sea-level curves formulated for the studied sections through the Paleocene show three falls in sea level, the last of which coincides with the LPE. The relative sea-level curves are considered to represent eustatic changes in sea level and thus the fall that coincides with the LPE may record development of continental ice on Antarctica. The two interpreted falls in sea level prior to the LPE are also commonly associated with dominantly siliceous productivity and may record precursor cooling events. The occurrence of possible “dropstones” in Early to Late Paleocene strata at one section may also record fluctuations between glacial and interglacial conditions prior to, and possibly within, the LPE. There is presently inconclusive evidence for the Akitio River section recording the Early Oligocene Marshall Unconformity, but the glaucony bearing unit that has been suggested to mark the event is similar to some LPE lithofacies and is associated with an episode of increased biosiliceous productivity, supportive of climate cooling. Collectively these features suggest that the LPE may be associated with marked cooling and continental ice development on Antarctica, well before the circum-Antarctic seaway had widened sufficiently to allow thermal isolation of the Antarctic continent. This suggests that Antarctic ice sheet growth is less reliant on ocean heat transport than currently believed, and other mechanisms, such as draw down of atmospheric CO2, may also be involved. Other results from this study of less relevance to early Paleogene marine climate but of interest to general eastern North Island geology include the possible identification of Awhea Formation and Waipawa Formation at the Pahaoa coastal section in Wairarapa; interpretations of the depositional environments for the lithofacies in the study sections, involving dominantly hemipelagic upper to lower slope mudstone with occasional mass emplaced sandstone and pelagic limestone deposits; a suggested mechanism that led to organic matter enrichment in the Waipawa Formation; a possible explanation for the lateral transition of thick deposits of organic rich mudstone to relatively thin deposits of greensand and glauconitic mudstone; possible explanations for lateral variations in redox conditions; the possible correlation of an Early Eocene olistrostromic unit at Pahaoa with an olistrostomic unit farther south, suggestive of a major tectonic episode; and confirmation of an anomalous trend, noted by previous studies on several Paleocene-Eocene sections, within the Wanstead Formation of increasing terrigenous sediment input during a transgressive period.

title: “It was… like a fight and rape club”: A foucauldian discourse analysis of New Zealand’s abuse in care inquiry, exploring child sexual abuse in residential care

authors: Simpson, Karen

subjects: child sexual abuse

abstract: Children and adolescents brought to the attention of New Zealand care and protection authorities are sometimes removed from their homes and placed into State-run residential care facilities. While the aim placing young people into residences is to improve their wellbeing, child sexual abuse is common in this setting and more pronounced than in the general population. There are many psychological theories, perspectives and movements which have attempted to explain child sexual abuse spanning from the 1800s to the present day. These partial and, at times, unsupported understandings of abuse have been shaped by socio-cultural and socio-political conditions. This has had serious implications for our collective (mis)understanding of child sexual abuse and the ways in which we respond to abuse with dominant discourse often transcending into policy, law, and the courtroom where social (in)justice occurs. In addition, despite there being three centuries of child sexual abuse research, to-date there has been limited exploration of the phenomenon in residential care settings both globally and within Aotearoa. However, the opportunity to explore child sexual abuse in this setting has availed itself with the New Zealand Government launching a Royal Commission of Inquiry into Abuse in Care in 2018 to better understand abuse across State and faith-based settings between 1950 and 1999. This thesis aims to provide additional insights to the inquiry by exploring the different ways in which child sexual abuse in residential care is understood as well as the conditions which legitimise or silence these understandings.

A Foucauldian Discourse Analysis was used to analyse 47 publicly available documents from the inquiry including statements, transcripts, and evidence briefs from survivors, survivor advocates, counsel, and representatives from institutions that provide care and protection for young people. Analysis found six discourses: control and punishment, fabrication, harmful, power and oppression, shameful, and State and institutional failure. These discourses reaffirm previous findings in sexual abuse research including sexual abuse as shameful and notions of fabrication. New insights were also found and include the use of sexual abuse as a method of controlling and punishing young people; predatory sexual behaviour in young people as a method of self-protection; cultural genocide and intergenerational care placement as victim sequelae; and the development of adaptive survival behaviours in residents in response to the State’s failures to protect them. In addition, systemic failures were uncovered including inadequacies in internal and external monitoring, failures in vetting, poor investment in professional capabilities of frontline workers, and a culture of tolerance toward abuse. Overall, the analysis found cultures of sexual violence and cultures of tolerance toward abuse within residential care, which emerge from the young person’s status as a State Ward.
