The role of different sources of communication and trust in reducing change-related uncertainties during organisational change

The current paper presents a qualitadve study of the role of different sources of communicadon in reducing change-related uncertaintj' experienced by employees during organisadonal change. The paper examines the role of trust in influencing how employees' appraise informadon from different sources within organisadons. Interviews with 19 employees from a range of organisadons idendfy the different types of change-related uncertaindes experienced during change. In addidon, the different sources of communicadon utilised by employees are idendfied and the role each source plays in reducing the different t}'pes of uncertaint}' invesdgated. From employee responses it is evident that t)'pically supervisors are the best source of change informadon, while communicadon from senior management usually focuses on strategic issues. Employees indicate that communicadon with coworkers operates as a support mechanism providing an avenue to share grievances arising from the change. Finally, trust is idendfied as playing an important role in influencing who employees go to for informadon when experiencing uncertainty'. ImpUcadons for change management research in addidon to pracdcal implicadons are discussed.

'Nothing good ever came out of Japan': Race-mixing and the limits of diaspora

This paper argues that postcolonial notions of diaspora are premised on immigrant subjectivities and standpoints which do not fully apprehend the mixed-race / bi-racial experience and the local effect of cultural hybridity in Western settings. The paper was prompted by a recent conversation with Dee, the daughter of a Japanese warbride. As a child Dee recalled being told by her friend's mother that 'nothing good ever came out of Japan'. The significance of constant interpolations into 'Asianness' by statements such as these; by the 'where do you come from?' question and by more blatant discriminations are inadequately addressed by traditional and postcolonial notions of diaspora. 'Roots' and 'routes' imagery feature prominently in discussions of diaspora and hybridity which aim to decolonise culture and identity in deconstructive moves that highlight their flexible, multiple, contractedness. While it has been argued that even these conceptualisations are problematic because they privilege orders of explanation, theory and standpoint that are forced back into line with traditional notions of discrete 'races', cultures, ethnicities and identities, cultural studies and postcolonial theorists do not appear to find this contradiction overly troubling. Lodged in bodies that do not easily conflate to neat either/or cultures, politics and genetics, race-mixing also defies and yet return us to culture and biology. However, I argue that their refractions though the same tired old orders of racial, ethnic, cultural and national differentiation prevent us from disregarding the discursive effects of racism and racialisation.

Distortion product otoacoustic emissions in school children: Effects to gender, ear asymmetry and handedness

Accurate interpretation of distortion product otoacoustic emission (DPOAE) data cannot be made without realizing the effects of non-pathological factors on DPOAEs. The present study aimed to examine the effects of ear asymmetry, gender and handedness on DPOAEs obtained from school children. One thousand and three children (528 boys and 475 girls) with a mean age of 6.2 years (SD = 0.4, range = 5.2 7.9 years) were tested in a quiet room at their schools using the GSI-60 DPOAE system. The stimuli consisted of two pure tones of different frequencies f1 and f2 presented at 65 and 55dB SPL respectively. A DP-gram was obtained for each ear with f2 varying from 1.1 to 6.0 kHz and the ratio of f2/f1 being kept at 1.21. The signal-to-noise ratios (SNR) (DPOAE amplitude minus the mean noise floor) at the tested frequencies 1.1, 1.5, 1.9, 2.4, 3.0, 3.8, 4.8, and 6.0 kHz were measured. The results revealed a small, but significant difference in SNR between ears, with right ears showing a higher mean SNR than left ears at 1.9, 3.0, 3.8 and 6.0 kHz. At these frequencies, the difference in mean SNR between ears was less than 1 dB. A significant gender effect was also found, with girls exhibiting a higher SNR than boys at 3.8, 4.8 and 6.0 kHz. The difference in mean SNR, as a result of the gender effect, was about 1 to 2 dB at these frequencies. The results from the present study indicated no significant difference in mean SNR between left-handed and right-handed children for all tested frequencies. In conclusion, these non-pathological characteristics of DPOAEs should be considered in the interpretation of DPOAE results for school children.

Finite-size effects and error-free communication in Gaussian channels

The efficacy of a specially constructed Gallager-type error-correcting code to communication in a Gaussian channel is examined. The construction is based on the introduction of complex matrices, used in both encoding and decoding, which comprise sub-matrices of cascading connection values. The finite-size effects are estimated for comparing the results with the bounds set by Shannon. The critical noise level achieved for certain code rates and infinitely large systems nearly saturates the bounds set by Shannon even when the connectivity used is low.

Dangerous brown men:exploiting sex, violence and feminism in the 'war on terror'

Why is the public presentation of the war on terror suffused with sexualised racism? What does this tell us about ideas of gender, sexuality, religious and political identity and the role of the state in the Western powers? Can we diffuse inter-ethnic conflicts and change the way the West pursues its security agenda by understanding the role of sexualised racism in the war on terror? In asking such questions, Gargi Bhattacharyya considers how the concepts of imperialism, feminism, terror and security can be applied, in order to build on the influential debates about the sexualised character of colonialism. She examines the way in which western imperial violence has been associated with the rhetoric of rights and democracy - a project of bombing for freedom that has called into question the validity of western conceptions of democracy, rights and feminism. Such rhetoric has given rise to actions that go beyond simply protecting western interests or securing access to scarce resources and appear to be beyond instrumental reason. The articulations of racism that appear with the war on terror are animated by fears and sexual fantasies inexplicable by rational interest alone. There can be no resolution to this seemingly endless conflict without understanding the highly sexualised racism that animates it. Such an understanding threatens to pierce the heart of imperial relations, revealing their intense contradictions and uncovering attempts to normalise violent expropriation.

Ethnicities and values in a changing world

Recent debates about national identity, belonging and community cohesion can appear to suggest that ethnicity is a static entity and that ethnic difference is a source of conflict in itself. "Ethnicities and Values in a Changing World" presents an alternative account of ethnicity and calls into question models of community cohesion that present ethnicity as the source of antagonisms and differences that must be overcome. It suggests instead that ethnicity is itself multiple and changing and is unlikely to be a basis for articulating shared values. This volume brings together an international team of leading scholars in the field of ethnic studies in order to examine innovative articulations of ethnicity and challenge the contention that ethnicity is static or that it necessarily represents traditional values and cultures. Asserting that ethnicity is deployed in part as an expression of values and a model of ethical practice, this book examines displays of ethnicity as assertions of identity and statements about way of life, sense of entitlement and manner of connection to others. "Ethnicities and Values in a Changing World" draws together debates about the articulation of ethnic identity, the nature of our relation to each other and discussions of everyday ethics, thus engaging with discussions of racism, multiculturalism and community cohesion. As such, it will appeal not only to sociologists, but to anyone working in the fields of cultural studies, race and ethnicity, globalization, migration and anthropology.

Gender and subject in higher education

This thesis is concerned with the issue of gender inequality in higher education. It examines the relationship between gender and subject specialisation, looking in particular at the reasons for the predominance, at undergraduate level, of men in the physical sciences, and of women in the humanities. It investigates ideas of `masculinity' and `femininity' and how these relate to constructions of `science' and `arts'. The thesis argues that students choose which subject to study on the basis of certain qualities these subjects are seen to hold, and that these qualities have close connections with beliefs about `masculinity' and `femininity'. It examines this through an interview study of male and female students on six higher education courses: two university courses of physics, two university courses of English, a polytechnic course in communications and a polytechnic course in physical science. The interview study demonstrates that the science subjects are perceived by science students as more certain, more useful and more important than the humanities, and emphasise the value of their degree in gaining a well-paid and important job. Female science students, however, experience conflict between being `a good scientist' and being `feminine'. English and communications students emphasise the breadth, uncertainty and individuality of their subjects, and find science restrictive and narrow. They make little link between their degree and their future career. Men, however, feel no conflict between their identity as men and their chosen subject. It is argued that there is a close link between the construction of masculinity and the construction of physical science, but that English and communications are more ambivalent: in some senses `masculine', in some `feminine'. Men are advantaged in these subjects because of their greater visibility and assertiveness. The thesis concludes that the division between `science' and `arts' reinforces ideas of masculinity and femininity, and argues that female `failure' in education is in part the result of higher education's inability to transcend that division.
