The purpose of this study is to examine to what extent South African companies listed on the local stock exchange in the mining and food producer and retail sectors are including biodiversity-related issues in their integrated and sustainability reports. The study employs established biodiversity reporting frameworks for gauging changes in the frequency of disclosures from 2011 to 2013 and determining if biodiversity information is being included in either the integrated or sustainability reports of the companies under review. Consistent with the findings of a special edition of Accounting, Auditing and Accountability Journal (AAAJ), the research finds few examples of detailed reporting on biodiversity issues. This is despite the fact that South Africa has a well-established code of corporate governance, a long history of including non-financial information in corporate reports and is an advocate of the integrated reporting movement. The study calls into question the sincerity of companies in the two sectors under review when it comes to providing balanced accounts of their management of non-financial capital as recommended by the country’s codes on governance and the International Integrated Reporting Council.

Purpose This study aims to examine biodiversity reporting by South African food producers and retailers. It not only draws attention to the disconnect between reporting on an important environmental issue and the sense of commitment to environmental responsibility, but also shows that over time, organisations are becoming more proactive about biodiversity reporting. Design/methodology/approach The research uses a content analysis of sustainability and integrated reports and organised hypocrisy as a theoretical framework for analysing biodiversity-related disclosures. Findings Consistent with an organised hypocrisy framework, the research finds that the several companies rely on corporate reporting to emphasise actions and internal management strategies that are already producing favourable results. In contrast, mission statements, firm policy commitments and forward-looking analysis are avoided. There is, however, evidence to suggest that the gaps between corporate reporting and action may be giving companies the time to reform their practices, align biodiversity disclosures with genuine corporate action and move towards truly integrated business models. Research limitations/implications Poor biodiversity reporting raises questions about the extent to which companies are managing serious environmental issues that can have a direct impact on their business models. Improvements in biodiversity reporting also suggest that corporate reporting is maturing and that some organisations are beginning to understand the need for managing their biodiversity impact. Originality/value The paper offers empirical evidence on how the disconnect between organisational rhetoric and action is used to manage stakeholder expectations and negate the need for environmental reforms. In this manner, organised hypocrisy is framed as a specific legitimisation strategy. The research also shows that organised hypocrisy is not absolute; despite the opportunity to engage in organised hypocrisy, some companies are taking a more proactive approach to biodiversity reporting. As a result, it may be appropriate to see organised hypocrisy as part of a transition to higher quality integrated or sustainability reporting.

The analysis aims to identify and explain how ideology is constructed and presented through language used in two Pakistani newspapers, viz., the Nation and the Dawn. Emphasis is placed on the construction of ideology using framework of analyzing media discourse given by van Dijk (1998) thus revealing the close relationship between language and ideology. The findings indicate that lexical choices and sentence structure in written text play a fundamental role in propagation and perpetuation of implicit and dominant ideologies and that there are certain ideological differences that are yielded either tacitly or overtly in newspaper editorials. The article is divided into four sections. The first section includes the introduction of the newspaper editorial. The next two sections describe what critical discourse analysis is, framework of Van Dijk"s media discourse model, brief history of the newspaper under investigation and an analysis of the data. The last section offers concluding remarks about the association between language and ideology.

Background: The standard treatment modalities for prostate cancer include surgery, chemotherapy, hormonal therapy and radiation therapy or any combination depending on the stage of the tumour. Radiation therapy is a common and effective treatment modality for low-intermediate-risk patients with localised prostate cancer, to treat the intact prostate and seminal vesicles or prostate bed post prostatectomy. However, for high-risk patients with lymph node involvement, treatment with radiation will usually include treatment of the whole pelvis to cover the prostate and seminal vesicles or prostate bed and the pelvic lymph nodes followed by a boost delivery dose to the prostate and seminal vesicles or prostate bed. Materials and Methods: We retrospectively analysed the treatment plans for 179 prostate cancer patients treated at the cancer centre with the volumetric-modulated arc therapy (VMAT) technique via RapidArc using 6 MV photon beam. Patients were either treated with a total prescription dose of 78 Gy in 39 fractions for patients with intact prostate or 66 Gy in 33 fractions for post prostatectomy patients. Results: There were 114 (64%) patients treated with 78 Gy/39 and 65 (36%) treated with 66 Gy/34. The mean homogeneity index (HI), conformity index (CI) and uniformity index (UI) for the PTV-primary of patients treated with 78 Gy are 0.06 ± 0.01, 1.04 ± 0.01 and 0.99 ± 0.01, respectively, and the corresponding mean values for patients treated with 66 Gy are 0.06 ± 0.02, 1.05 ± 0.01 and 0.99 ± 0.01, respectively. The mean PTV-primary V95%, V100% and V105% are 99.5 ± 0.5%, 78.8 ± 12.2% and 0.1 ± 0.5%, respectively, for patients treated with 78 Gy and 99.3 ± 0.9%, 78.1 ± 10.6% and 0.1 ± 0.4%, respectively, for patients treated with 66 Gy. The rectal V50Gy, V65Gy, V66.6Gy, V70Gy, V75Gy and V80Gy are 26.8 ± 9.1%, 14.2 ± 5.3%, 13.1 ± 5.0%, 10.8 ± 4.3%, 6.9 ± 3.1% and 0.1 ± 0.1%, respectively, for patients treated with 78 Gy and 33.7 ± 8.4%, 14.1 ± 4.5%, 6.7 ± 4.5%, 0.0 ± 0.2%, 0.0% and 0.0%, respectively, for patients treated with 66 Gy. Conclusion: The use of VMAT technique for radiation therapy of high-risk prostate cancer patients is an efficient and reliable method for achieving superior dose conformity, uniformity and homogeneity to the PTV and minimal doses to the organs at risk. Results from this study provide the basis for the development and implementation of consistent treatment criteria in radiotherapy programs, have the potential to establish an evaluation process to define a consistent, standardised and transparent treatment path for all patients that reduces significant variations in the acceptability of treatment plans and potentially improve patient standard of care.

NAC transcription factors are considered as main family of transcriptional regulators in plants. NAC gene family members play significant contribution in regulating transcriptional reprogramming in plants related to plant stress response. These proteins possess highly conserved DNA binding domains and play a diverse functions in several plants. NAC gene is related to several stress factors including biotic and abiotic factors. NAC transcription factors controls several interrelated processes and their protein products can function as negative or positive regulators in many cellular processes. These regulatory functions are also controlled by NAC proteins such as auto and cross regulation. These regulatory proteins are regarded as a central regulator for the interaction of phyto hormones in various stress signaling pathways. This review highlights the role of NAC transcription factors in modulating gene expression and their role in various biotic and abiotic stress tolerance in plants.
