title: Transient vibration analysis of a completely free plate using modes obtained by Gorman's superposition method

authors: Ilanko, Sinniah

subjects: transient vibration

abstract: This paper shows that the transient response of a plate undergoing flexural vibration can be calculated accurately and efficiently using the natural frequencies and modes obtained from the superposition method. The response of a completely free plate is used to demonstrate this. The case considered is one where all supports of a simply supported thin rectangular plate under self weight are suddenly removed. The resulting motion consists of a combination of the natural modes of a completely free plate. The modal superposition method is used for determining the transient response, and the natural frequencies and mode shapes of the plates used are obtained by Gorman's superposition method. These are compared with corresponding results based on the modes using the Rayleigh–Ritz method using the ordinary and degenerated free–free beam functions. There is an excellent agreement between the results from both approaches but the superposition method has shown faster convergence and the results may serve as benchmarks for the transient response of completely free plates.

title: Perceived organizational support, organizational cynicism and employee well-being

authors: Peplinski, Marin Sara

subjects: Perceived Organizational Support

abstract: The present study examined how an employee’s perception of their employing organization can impact his or her thoughts, feelings and behaviors. This study examined cognitive, affective and behavioral organizational cynicism in relation to perceived organizational support. Psychological strain, self-reported physical health and turnover intentions were investigated in relation to reduced POS and increased organizational cynicism. 
An online questionnaire measuring perceived organizational support (POS), organizational cynicism, psychological strain, turnover intentions and self-reported physical health was administered to full-time American employees, who were not self-employed, via links posted to social media websites and also circulated through a manufacturing company’s human resources headquarters. Two groups of participants responded, yielding a total sample of 161 participants. Group 1 consisted of participants from all industry types recruited using social media. Group 2 consisted of employees from the human resources headquarters of the manufacturing company. Groups differed significantly on almost all variables. This difference was controlled for in all analyses. Correlations and multiple regression analyses were used to test the hypotheses. All of the hypothesized correlational relationships were supported. Results of this study supported the notion that the multi-dimensional attitude of organizational cynicism is strongly and inversely related to POS. Contrary to predictions, affective and cognitive organizational cynicism did not mediate the majority of the hypothesized relationships between variables. This may have been due to the multicollinearity of the predictor variables. Significant mediation analyses results included: full mediation between POS and social dysfunction by cognitive organizational cynicism; partial mediation between anxiety/depression and self-reported physical health by affective organizational cynicism; and, the partial mediation of affective organizational cynicism between POS and turnover intentions. 
Future research may benefit from measuring the variables at different points in time in order to investigate causality between variables and also to avoid any statistical confounds such as multicollinearity. The identification of the high correlations between variables may encourage employers to actively attempt to address levels of POS within their organization thus resulting in benefits for employees.

title: New Zealand history is Maori history: Tikanga as the ethical foundation of historical scholarship In Aotearoa New Zealand

authors: Mahuika, Nepia

subjects: Arts & Humanities

abstract: IT SHOULD COME AS NO SURPRISE TO FIND that New Zealand history is Māori history. In 1987 when Tipene O’Regan stated that the ‘the past belongs to all New Zealanders, but first it is ours’, he was drawing attention to New Zealand history’s foundation in Māori history.1 Thinking about New Zealand history as Māori history does not mean denying the histories of European, Asian and Pasifika immigrants, but draws attention to the notion that ‘settler’ aspirations to claim ‘Aotearoa’ as home occur within a much broader narrative of indigenous occupation and struggle.2 Indeed, how can New Zealand history be the story of ‘here’ when it has ‘othered’ indigenous narratives that speak to the heart of what it is to belong in the land of the long white cloud? Yes, New Zealand history is Māori history – and that presents a problem for tangata whenua self-determination. Likewise, for Pākehā, it is an issue because until New Zealand history recognizes and enables the centrality of Māori history it will always fail to articulate the collective ‘us’ that is so often assumed in the discourse of ‘full and final settlement’.3 In its current form it will never be able to ethically or adequately account for the shaping of a New Zealand identity that finds ‘composure’ in the story of how Pākehā became ‘native’ New Zealanders.4 For Māori, these issues are keenly felt, because while New Zealand history has always been about us, it has predominantly been articulated on the colonizers’ terms. In the ‘discursive constructions’ that are New Zealand histories, the indigenous have regularly been culturally appropriated, dislocated and misrepresented.5 Even when Māori have turned their back on the writing of New Zealand history it has been, and will still be, a history of being or becoming ‘native’. Yes, New Zealand history is Māori history – so why does it feel like the story of Pākehā settlers?
