Reconceptualising employee silence: problems and prognosis

A growing literature has emerged on employee silence, located within the field of organisational behaviour. Scholars have investigated when and how employees articulate voice and when and how they will opt for silence. While offering many insights, this analysis is inherently one-sided in its interpretation of silence as a product of employee motivations. An alternative reading of silence is offered which focuses on the role of management. Using the non-union employee representation literature for illustrative purposes, the significance of management in structuring employee silence is considered. Highlighted are the ways in which management, through agenda-setting and institutional structures, can perpetuate silence over a range of issues, thereby organising employees out of the voice process. These considerations are redeployed to offer a dialectical interpretation of employee silence in a conceptual framework to assist further research and analysis.

On Suffering and Sympathy: Jude the Obscure, Evolution and Ethics

This article links Thomas Hardy’s exploration of sympathy in Jude the Obscure to contemporary scientific debates over moral evolution. Tracing the relationship between pessimism, progressivism, and determinism in Hardy’s understanding of sympathy, it also considers Hardy’s conception of the author as enlarger of “social sympathies”--a position, I argue, that was shaped by Leslie Stephen’s advocacy of novel writing as moral art. Considering Hardy’s engagement with writings by Charles Darwin, T. H. Huxley, Herbert Spencer, and others, I explore the novel’s participation in a debate about the evolutionary significance of sympathy and its implications for Hardy’s understanding of moral agency. Hardy, I suggest, offered a stronger defence of morality based on biological determinism than Darwin, but this determinism was linked to an unexpected evolutionary optimism.

Policing the Globe: State Sovereignty and the International in the Post-9/11 Crime Novel

Two recent studies of 9/11 literature are dismissive of the contributions that crime and espionage novels have made to ongoing efforts to map the significance of 9/11 and its aftermath. My essay contests the assumption that only literary fiction – which pays sufficient attention to trauma – can “bear witness” to the events of 9/11 and argues that such fiction is, in fact, singularly ill-equipped to illuminate the complex geo-political circumstances that 9/11 entrenched and transformed. By contrast, genre novels by John Le Carré and Don Winslow have responded in imaginative and critical ways to post-9/11 and avowedly trans-national securitization initiatives and hence to efforts to trouble traditional accounts of state sovereignty.

Prognostic significance of thymidylate synthase, dihydropyrimidine dehydrogenase and thymidine phosphorylase protein expression in colorectal cancer patients treated with or without 5-fluorouracil-based chemotherapy

Background: Low tumour expression levels of thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD) and thymidine phosphorylase (TP) have been linked with improved outcome for colorectal cancer (CRC) patients treated with 5-fluorouracil (5-FU). It is unclear whether this occurs because such tumours have better prognosis or they are more sensitive to 5-FU treatment.

Tissue microarrays characterise the clinical significance of a VEGF-A protein expression signature in gastrointestinal stromal tumours

A tissue microarray analysis of 22 proteins in gastrointestinal stromal tumours ( GIST), followed by an unsupervised, hierarchical monothetic cluster statistical analysis of the results, allowed us to detect a vascular endothelial growth factor ( VEGF) protein overexpression signature discriminator of prognosis in GIST, and discover novel VEGF-A DNA variants that may have functional significance.

What is the significance of muciphages in colorectal biopsies?

Muciphages (mucin-containing macrophages), first described in 1966 by Azzopardi & Evans, are a common feature of biopsies of large intestinal mucosa, even in the absence of other abnormalities such as active inflammation or evidence of chronic inflammatory bowel disease. Should they be mentioned in diagnostic reports? Do muciphages reliably indicate previous mucosal disease, now quiescent? In the following articles, Salto-Tellez & Price review what is known about muciphages and conclude that they reflect previous occult and clinically unimportant mucosal damage and that, in an otherwise normal colorectal mucosa, they have no diagnostic significance; and Shepherd draws attention to a wide range of clinically much more significant mucosal infiltrates that could be mistakenly regarded as muciphages and thus overlooked.

Prognostic Significance of TRAIL Signaling Molecules in Stage II and III Colorectal Cancer

Purpose: We previously found that cellular FLICE-inhibitory protein (c-FLIP), caspase 8, and tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) receptor 2 (DR5) are major regulators of cell viability and chemotherapy-induced apoptosis in colorectal cancer. In this study, we determined the prognostic significance of c-FLIP, caspase 8, TRAIL and DR5 expression in tissues from patients with stage II and III colorectal cancer.

Experimental Design: Tissue microarrays were constructed from matched normal and tumor tissue derived from patients (n = 253) enrolled in a phase III trial of adjuvant 5-fluorouracil–based chemotherapy versus postoperative observation alone. TRAIL, DR5, caspase 8, and c-FLIP expression levels were determined by immunohistochemistry.

Results: Colorectal tumors displayed significantly higher expression levels of c-FLIP (P < 0.001), caspase 8 (P = 0.01), and DR5 (P < 0.001), but lower levels of TRAIL (P < 0.001) compared with matched normal tissue. In univariate analysis, higher TRAIL expression in the tumor was associated with worse overall survival (P = 0.026), with a trend to decreased relapse-free survival (RFS; P = 0.06), and higher tumor c-FLIP expression was associated with a significantly decreased RFS (P = 0.015). Using multivariate predictive modeling for RFS in all patients and including all biomarkers, age, treatment, and stage, we found that the model was significant when the mean tumor c-FLIP expression score and disease stage were included (P < 0.001). As regards overall survival, the overall model was predictive when both TRAIL expression and disease stage were included (P < 0.001).

Conclusions: High c-FLIP and TRAIL expression may be independent adverse prognostic markers in stage II and III colorectal cancer and might identify patients most at risk of relapse.

Realising political equality: the European Court of Human Rights and positive obligations in a democracy'

The European Convention on Human Rights (ECHR) speaks of the importance of an “effective political democracy” in its Preamble, though it is only in Article 3 of Protocol 1 (P1-3) that we find a right to free elections. This paper discusses the role of “positive obligations” under P1-3. This paper outlines the positive obligations in P1-3 focusing on obligations where the state is required to do more than just change the law. This may mean providing resources or facilities, adopting regulatory frameworks or creating new institutions. The paper highlights specific positive obligations that need to be further developed in the jurisprudence of the European Court of Human Rights (ECtHR). Sometimes these can be developed by analogy with positive obligations recognised in other areas of ECtHR jurisprudence. However, beyond these cases, states should ensure that members of vulnerable and disadvantaged minorities are able to participate in the electoral process and should ensure that dominant political groups cannot abuse their political power to exclude other parties unfairly. This is necessary to realise equal political rights. The second section of this paper sketches some preliminary points about the Strasbourg institutions’ approach to P1-3. After that, the third section identifies circumstances where the ECtHR should apply a more intense scrutiny in P1-3 cases. The fourth, fifth and sixth sections look at positive obligations relating to the right to vote, the right to run for election and the regulation of political parties.
