An assessment of organisational justice perceptions across three generational cohorts
Authors: Ledimo Ophillia
Published: March 2017

Despite several reviews of generational differences across cohorts regarding their career stages in organisations, relatively few empirical investigations have been conducted to understand these cohorts’s behaviour and perceptions. Hence there is paucity of studies that explored the generational differences on the construct organisational justice across generational cohorts. The objective of this study was to assess the differences across three generational cohorts (Millennials, Generation X, and Baby Boomers) on dimensions of the organisational justice construct using the Organisational Justice Measurement Instrument (OJMI). Data was collected through the administration of OJMI to a random sample size of organisational employees (n=289). Descriptive statistics and analysis of variance were conducted to interpret the data. These findings provide evidence that differences do exist across cohorts on dimensions of organisational justice, and some differences may be a result of respondents’ different perception of their organisation’s practices and processes. In terms of contributions and practical implications, insight gained from the findings may be used in proposing organisational development interventions to manage multigenerational employees as well as to conduct future research.

Colonization of the Beaufort Coastal Plain by Beaver (Castor canadensis): A Response to Shrubification of the Tundra?
Authors: Jung Thomas S , Frandsen Jay , Gordon Danny C , Mossop David H
Published: March 2017

A consequence of rapid global warming has been the shrubification (increase in shrub abundance, cover, and biomass) of arctic and alpine tundra ecosystems. Shrubification is likely a key driver of predicted and observed changes in the biodiversity of the Arctic. The American Beaver (Castor canadensis) has a vast distributional range, covering most of north America below the tree line; however, it has not been recorded in tundra habitat of the Beaufort Coastal Plain of Yukon and Alaska. in 2015, we observed a beaver dam, lodge, and winter food cache on the Babbage River in Ivvavik National Park, Yukon, Canada. Local Inuvialuit hunters first observed beavers on two rivers immediately east of the Babbage River in 2008 and 2009. Together, these are the first observations of beavers on the Beaufort Coastal Plain and indicate initial attempts at colonization. Colonization of the Beaufort Coastal Plain by beavers may have been facilitated by shrubification of river valleys on the tundra of northern Yukon and adjacent Alaska, which is a consequence of rapid climate warming in the western Arctic.
Material compuesto de matriz polipropileno (PP) y fibra de cedro: influencia del compatibilizante PP-g-MA
Authors: Caicedo Carolina , Vázquez Arce Aldo , Crespo Lina Marcela , De la Cruz Hever , Ossa Ómar Hernán
Published: March 2017

Debido a que la fuerza de los compuestos de madera y plástico (CMP) se basa en la interacción fibra-matriz, se ha estudiado la influencia del agente compatibilizante al modificar la matriz plástica con diferentes proporciones de polipropileno injertado con anhídrido maléico (PP-g-MA). Por lo tanto, se evaluaron las propiedades térmicas y mecánicas de una nueva serie de CMP con 20% de fibra mediante la técnica de inyección. Cabe mencionar que en la etapa previa al proceso de inyección, estos materiales fueron mezclados en una extrusora de doble husillo co-rotante, en condiciones suaves debido a que se logró disminuir en un 50% el tiempo de residencia de la fibra con respecto al polímero. Los resultados de los análisis termogravimétricos obtenidos de los productos extruidos de CMP presentaron una temperatura de degradación con valores intermedios de T10 ~295 °C respecto a los componentes de partida (Fibra, PP). Los productos finales presentaron una pérdida de ~3.4% asociada al segundo proceso térmico que sufrió el material. El análisis mecánico presentó un aumento en la resistencia a la tensión del 20.3% en el nuevo CMP, mientras que la resistencia a la flexión alcanzó un 46.2%. En el análisis micro-estructural de los productos finales se observó la incorporación de la fibra en la matriz mediante microscopia electrónica de barrido. Finalmente, se determinó la relación óptima de la mezcla para lograr un incremento significativo en las propiedades mecánicas.

Published: March 2017

Este trabajo describe la obtención de paneles de ferrocemento con la incorporación de agregado fino reciclado (AFR) obtenidos a partir de la trituración de escombros de concreto. Se partió de la obtención de un mortero referencia que cumpliera con la resistencia mínima a la compresión requerida para esta aplicación (25 MPa a los 28 días de curado) y asentamiento máximo de 6 cm. Se estudió el efecto sobre la resistencia a la compresión de este mortero de referencia, de la incorporación de AFR en niveles de 25%, 50%, 75% y 100%. Posteriormente y con base en resultados óptimos se elaboraron paneles de ferrocemento utilizando barras de acero, malla hexagonal y malla zaranda (ZAG). Los resultados obtenidos revelan la posibilidad de sustituir totalmente la arena natural por AFR en la fabricación de paneles de ferrocemento con resistencias a la flexión de hasta 34,16 MPa y morteros con resistencias a la compresión superiores a 7,3% a los basados en un 100% de arena natural.

Honouring the Voices of the Ancestors - A Personal View of the Effect of Māori Language Immersion Education in Aotearoa-New Zealand
Authors: Mahuta Dean
Published: March 2017

Many studies have been undertaken which focus on identifying factors which impact on the participation and achievement of Māori students in post compulsory education and factors contributing to Māori success in tertiary education.  (Jefferies, R. 1997; Tiakiwai, S.J. 2001; Nikora, L. W., Levy, M., Henry, J., & Whangapirita, L. 2002; Greenwood, J., & Te Aika, L. 2009), One of the factors identified as an institutional barrier is a lack of recognition of Māori culture and language.  This article discusses the importance of university Māori language students being able to write their assignments, dissertations and theses not only in the Māori language, but in their own tribal dialects.   Using a case-study approach of the authors’ personal experiences of primary, secondary and tertiary education, the case-study will focus specifically on the place of the authors’ tribal identity and dialect in this process.  Dialect will be illustrated through samples of work submitted for the authors BA (Hons) dissertation, MA and PhD. This will also demonstrate the importance of writing in the community language, when conducting research on a topic related to that community, and this will be discussed in terms of reflecting a commitment to the survival of that community language and to increasing the corpus of work being produced in the Māori language.

 

This case-study, adopting a narrative approach, will demonstrate a positive outcome for both a university and a Māori student when a) the university provides the right pathways, policies and processes to empower Māori students to write in their native tongue; and b) the student has the courage and tenacity to continue writing in the Māori language and in their dialect, as a minority in the institution.
Making a difference: The role of the Māori administrator in Universities
Authors: Smith Tania
Published: March 2017

The Tertiary Education Strategy 2010 – 2015 in Aotearoa/New Zealand states that the Government aims to ‘increase the number of Māori students achieving at the higher level’ (Tertiary Education Commission 2010, p10). For this to be achieved universities need to play their part in assisting Māori students to progress beyond the undergraduate degree and into postgraduate study.

Universities take their origins from western European values, ideals and world view which are reflected in the curriculum, management systems and processes.  It is predicated that by 2020 over half the tertiary student population will be Māori due to a youthful Māori population (Department of Labour, 2008). This will be a challenge for universities.  Therefore, the role of a Māori administrator within the university system becomes critical in being able to provide useful insight to the university on how to retain Māori students in this changing environment.

This paper draws on my Master of Philosophy research.  It will critically examine the role Māori administrator’s play in the recruitment and retention of Māori students in universities in Aotearoa/New Zealand including culturally specific pastoral care, accurate course advice, information on degree requirements, appropriate learning pathways for students and supporting academic staff to track student progress through to completion. These additional responsibilities, often unrecognised by the university, demonstrates the important role a Māori administrator can make in retaining Māori students in the academy.
Climate-Change Blues: Sustaining Village Life in Tonga
Authors: Brown Pulu Teena
Published: March 2017

The loss of small island states will affect us all.  Climate change refugees will become a very serious issue for all countries.

Lord Ma’af

On the afternoon of December 15th 2009, Tonga’s Minister for Environment and Climate Change, Lord Ma’afu, made a passionate plea to the international press assembled at the 15th United Nations Climate Change Conference in Copenhagen, Denmark.  He had a message he wanted to get out to the world.  Politically, Ma’afu awoke a subconscious fear developed countries stepped around not wanting to stir and be forced to deal with.  Snared in the small island uncertainty of rising sea levels was the inevitability climate change refugees might need another place to live (Bedford and Bedford, 2010; Fagan, 2013).  Where would they go?  Who would take them in?  What countries would help the Pacific Islands?

Despite sociologists and political scientists documenting the failure of global governance to deliver a legally binding agreement for controlling climate change (Giddens, 2009; Held and Hervey, 2009; Fisher, 2004), alternatives put forward have not been taken up.  What other methods for governing over bad weather are there? (Goldin, 2013).  And how is village life in Tonga coping with climate blues?
Minerals and Cucumbers in the Sea: International relations will transform the Tongan state
Authors: Brown Pulu Teena
Published: March 2017

Constitution law researcher Guy Powles, a Pakeha New Zealander residing in Australia was not optimistic accurate predictions on “the [Tonga] election which is coming up now in November” could be made (Garrett, 2014).  “A man would be a fool to try to guess just where the balance will finish up,” he uttered to Jemima Garrett interviewing him for Radio Australia on April 30th 2014 (Garrett, 2014).  Picturing the general election seven months away on November 27th 2014, Powles thought devolving the monarch’s executive powers to government by constitutional reform was Tonga’s priority.  Whether it would end up an election issue deciding which way the public voted was a different story, and one he was not willing to take a punt on.

While Tongans and non-Tongan observers focused attention on guessing who would get into parliament and have a chance at forming a government after votes had been casted in the November election, the trying political conditions the state functioned, floundered, and fell in, were overlooked.  It was as if the Tongans and Palangi (white, European) commentators naively thought changing government would alter the internationally dictated circumstances a small island developing state was forced to work under.

The discovery of New Zealand, first by Polynesia and followed by Europe, have become important narratives in the nation’s evolving sense of identity.[i]  However, these narratives are neither straightforward in themselves, nor always completely complementary with each other.  The purpose of this particle is to explore some of the historical, cultural, and philosophical bases of these discovery myths, with a focus on their construction and reconstruction.  What emerges from this survey is that the discovery myths are an example of history being appropriated at times for ideological purposes, and that the character and content of these myths is necessarily fluid in order to accommodate the shifting requirements for which they are employed.

Indigenous Dance and the Nation: Conflation and Metonym
Authors: Patrick Declan
Published: March 2017

It is interesting, as a Kiwi living in Europe, to understand the ways in which New Zealand is perceived to those outside its borders. When I tell people I am from Aotearoa, their immediate reaction is to identify the country with images: beautiful scenery, the Lord of the Rings movies, sheep, and in particular rugby and the Haka. This ubiquitous image of the All Blacks performing a particular sequence of movement and sound before executing a performance of skill and strategy within the strict confines of an improvisational game is one explored by Stephen Jackson and Brendan Hokowhitu in their 2002 article Sports, Tribes and Technology: The New Zealand All Black Haka and the Politics of Identity. They suggest the conflation of rugby, the Haka and national identity is a deliberate representational strategy. While Jackson and Hokowhitu concentrate on the commercial aspects of this strategy, there is also a strong and present governmental presence within these representational strategies also.

Mika Haka Foundation: Performing Empowerment
Authors: Haka Mika , Keiha Pare , Mazer Sharon
Published: March 2017

Mika is famous for his boundary-bursting performances, and as a lifestyle liberationist who has used his brand more to create social change than to campaign for an Oscar. Working with young people, including those who might be termed ‘at risk’, has always been at his core, even if he’s kept that kind of work predominantly ‘in the closet’. He auditions them, trains them up, enforces health literacy, financial literacy and political and cultural awareness, whilst teaching them how to sing, dance, act and manage themselves onstage and off. He transforms these young people into ‘emerging leaders’, invests them with social capital and encourages them to perform their own empowerment. He’s been doing this a very long time, in fact: from the early 1980s in Christchurch with the Coloured Crew Lockers to his creation of Torotoro in the early 2000s, and now under the auspices of the Mika Haka Foundation. The images here offer a glimpse into Mika’s current collaborations, which will be the topic of a conversation between Mika and Pare Keiha, the Chair of the Mika Haka Foundation Trust Board, as moderated by Sharon Mazer at the Ka Haka Empowering Performance: Māori and Indigenous Performance Studies Symposium. We ask: how does educating young people as entrepreneurial entertainers potentially lead to their emancipation?
Te Arewhana Kei Roto i Te Rūma: An Indigenous Neo-Disputatio on Settler Society, Nullifying Te Tiriti, ‘Natural Resources’ and Our Collective Future in Aotearoa New Zealand
Authors: Simon Hemopereki Hoani
Published: March 2017

This practice-research based article explores the relationship between mana motuhake and white patriarchal sovereignty in Aotearoa New Zealand, focusing on Ngāti Tūwharetoa as a case study. It seeks to find the relevance of Aboriginal academic Aileen Moreton-Robinson’s white possessive doctrine to the Aotearoa New Zealand context. In particular, it highlights the racist nature of the law and planning systems and their inadequacies to provide for hapū and iwi. It provides a key theoretical analysis regarding the nature of white patriarchal sovereignty in Aotearoa and the need of the state to appear virtuous, to continue the legacy that started with the Treaty of Waitangi to maintain this whenua as a white possessive. Lastly, the piece questions the position of Britishness within Aotearoa New Zealand and asks key philosophical questions for all about the need to find common understandings or māramatanga about our collective future as a society.
Dancing from Te Kore into Te Ao Marama
Authors: Livermore Cathy
Published: March 2017

Contemporary Indigenous performance awakens and brings into ‘now’ the inherited mauri of all that we are, carried through the wairua from our ancestors and the whenua in the woven whariki of memory held in time and space. Whether in Aotearoa or on another’s whenua, on a stage, in someone’s lounge room or in the ngahere gathering rongoa, when we dance from te kore into te ao marama, we activate ihi, wehi and wana: a power that awakens within and between us and the universe. We come alive in the performance of our cultures and ourselves, see our living relevance today, and are uplifted by our potential to contribute to our world socially, culturally, politically, spiritually and personally. Māori culture activates in me keys and the tools, ways of moving and giving voice, the power to share who I am in my fullness today with other cultures. This presentation reflects on the power of my own current practice as it represents the culmination of my performances, dance teaching, cultural exchanges and facilitation experiences within New Zealand and internationally. How might performing as Maori and Indigenous peoples be seen to strengthen and empower our selves, communities and cultures, whoever and wherever we are in the creation of the future?
Solving the Location Area Problem by Using Differential Evolution
Authors: Almeida-Luz Sónia M. , Vega-Rodríguez Miguel A. , Gómez-Pulido Juan A. , Sánchez-Pérez Juan M.
Published: March 2017

In mobile networks, one of the hard tasks is to determine the best partitioning in the Location Area problem, but it is also an important strategy to try to reduce all the involved management costs. In this paper we present a new approach to solve the location management problem based on the Location Area partitioning, as a cost optimization problem. We use a Differential Evolution based algorithm to find the best configuration to the Location Areas in a mobile network. We try to find the best values for the Differential Evolution parameters as well as define the scheme that enables us to obtain better results, when compared to classical strategies and to other authors’ results. To obtain the best solution we develop four distinct experiments, each one applied to one Differential Evolution parameter. This is a new approach to this problem that has given us good results.
Ahh! Pathology
Authors: K.C. Geetika
Published: March 2017

Pathology was introduced to us as a study of disease, a bridge between basic science and clinical medicine. So it is. We as pathologist are intrigued by the diagnostic challenges faced in everyday reporting. A benign looking lipomatous lesion appears to have a lipoblast like cells in FNAC. However, the diagnosis is made guardedly considering it to be in the external surface and differential diagnosis of atypical lipoma or a hybernoma is given. Yes, we need peer reviews and further molecular tests in order to “narrow down” our possible differential diagnosis in the not so clear cases. This brings us to the undercurrent topic that lingers among some of the medical personals regarding pathology and its future. I, not so long ago, was asked to read an article regarding the future of pathology and its rather bleak prospect. Of course I ignored it feeling not in my life time. However, we cannot deny the surge of molecular analysis in the field of medicine and pathology is certainly not immune to it. On trying to find out some more on this topic I came across an interesting article by Juan Rosai.1 Now, to tell you the truth, the name itself was a big relief to calm down my nerves because Rosai is a genius. A Sherlock Homes of disease diagnosis. Written a decade ago, the article is relevant even today specially in our context. The failure to recognize the power of morphological analysis in H and E by a SKILLED observer has led to the increasing prediction of the demise of conventional microscopy. He states that “ Any new technique must provide information of prognostic or therapeutic significance beyond that provided by the current gold standard”.1 In 2006, National cancer institute in USA funded a $ 100 million project to have a new classification of tumors based on molecular parameters. One of the cancer biologist Lawrence Loeb said at the end of the study that “ From my perspective it is hopeless. It is a wonderful study, but there is no core of genes associated with a particular cancer. It stated with a wonderful optimism, but now it presents enormous complexity”.Though complexities might be necessary in some of instances, power of simplicity cannot be overrated. Simplicity with a bit of open mindedness and problem oriented attitude give far better results. A plethora of tests done in the initial stage without a clue of what you are looking for can be a like trying to find a needle in a haystack . What is needed for the pathologist of todays era is the ability to bridge the gap between the genotype and phenotype, a marriage of morphology with molecular diagnosis. So let there be no doubt. The role of pathologist is even greater now then ever before. As Hess puts it, we as a pathologist of “molecular era” need to provided primary diagnosis, determine whether a specific molecular target is present before initiation of therapy, evaluate the efficacy and possibility of side effects of new therapies and also harvest and analyze tissues in therapeutic failure. So much for the end of suffering.
