Internal business communications: a three dimensional problem

Communications is a dynamic field -- a company cannot afford to allow its communications program to become static. As an accomplished musician must practice to maintain his skill, so must a company sharpen and refine its communications. Conditions change and the communications program must change to meet the new needs. This will require continuing application of ingenuity and imagination in devising more effective ways of assembling, summarizing and disseminating information to coordinate the functions and activities of the organization

E-commerce and graduate education: is educational quality taking a nose dive?

Purpose: Online education has been growing rapidly, but has not had the benefit of the extensive teaching pedagogy development of traditional face-to-face teaching. This paper aims to provide a review of the current literature and present the results of a survey, conducted to determine the effectiveness of a graduate online subject. Design/methodology/approach: The literature was reviewed to identify measures of success and quality in online education delivery. These measures were then considered in relation to their application in practice via a case study based around a survey conducted at Deakin University in Australia. Findings: A total of 16 relevant measures of teaching quality were identified in the literature. Most measures had elements of bias and some were more generally applicable to online learning. The case study suggested that the value of computer mediated learning in an online environment was limited and that a combination of print and computer mediated conferencing performed better in more of the identified quality matrices. Practice implications: Online learning does not save teaching resources if standards of quality are maintained. It can be used to provide a remote teaching facility, provided it is backed up by resources such as printed study guides. For the subject evaluated, online mediated learning did not the provide the same quality of education. Originality/value: Whilst some research has been conducted in this area, no substantive grounded theory has been applied to postgraduate or fee-paying online education regimes. As a result, case studies of such applications can be very helpful in the design of future teaching systems. <br /

Is intimate partner violence more common in pregnant women with severe mental illness? A retrospective study

Objective: To examine the risk of past and current experiences of intimate partner violence (IPV) in women with severe mental illness (SMI) in pregnancy. Methods: We examined past and current experiences of IPV in women with SMI in pregnancy. The data of 304 women with SMI including schizophrenia and related psychotic disorders and Bipolar Disorder meeting International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) criteria were extracted from hospital records at King Edward Memorial Hospital, Western Australia. Comparisons were made between our study data and the Australian population data reported by the Australian Bureau of Statistics, which included data on pregnant women in Western Australia. Additional measures included reported demographics, substance use and pregnancy variables. Results: Around 48% of pregnant women with SMI had experienced IPV and were three times the risk when compared with the general pregnant population in Australia. There was no difference in rates of IPV in those women with psychotic disorders when compared with bipolar disorder. Furthermore, the rates of smoking and illicit substance use were significantly higher in pregnant women with SMI who experienced IPV compared with those who have not experienced IPV. Conclusion: These findings suggest women with SMI in pregnancy are at significantly higher risk of having experienced or experiencing IPV. In addition, IPV in pregnant women with SMI may increase the risk of smoking and illicit substance use. Together this suggests that maternity and mental health services should ensure there are both screening and support pathways for IPV that are developed and evaluated specifically for pregnant women with SMI

Power, status, and learning in organizations

This paper reviews the scholarly literature on the effects of social hierarchy—differences in power and status among organizational actors—on collective learning in organizations and groups. We begin with the observation that theories of organization and group learning have tended to adopt a rational system model, a model that emphasizes goal-directed and cooperative interactions between and among actors who may differ in knowledge and expertise but are undifferentiated with respect to power and status. Our review of the theoretical and empirical literatures on power, status, and learning suggests that social hierarchy can complicate a rational system model of collective learning by disrupting three critical learning-related processes: anchoring on shared goals, risk taking and experimentation, and knowledge sharing. We also find evidence to suggest that the stifling effects of power and status differences on collective learning can be mitigated when advantaged actors are collectively oriented. Indeed, our review suggests that higher-ranking actors who use their power and status in more “socialized” ways can play critical roles in stimulating collective learning behavior. We conclude by articulating several promising directions for future research that were suggested by our review

A spectroscopic investigation of the weathering of a heritage Sydney sandstone

Infrared spectroscopy has been employed in a study of the degradation of heritage Sydney sandstone used in St. Mary's Cathedral in Sydney, Australia. Spectra were used to characterise the clay components taken from weathered and unweathered sandstone blocks removed from the Cathedral as part of a restoration programme. Two types of kaolin clays - kaolinite and its polymorph, dickite - have been identified. A higher amount of dickite present in the clay of weathered sandstone indicated that a kaolinite-to-dickite transformation occurs upon weathering. X-ray photoelectron spectroscopy was also used to confirm the presence of a more thermally stable polymorph of the kaolinite in the sandstone. © 2008 Elsevier B.V. All rights reserved

ESEM-EDS investigation of the weathering of a heritage sydney sandstone

The degradation of Sydney sandstone used to build the heritage St Mary's Cathedral in Sydney, Australia, has been investigated using environmental scanning electron microscopy combined with energy dispersive X-ray spectroscopy. This technique provided the structural details of the cementing clay and an elemental characterization the sandstone. The observed differences in the elemental composition of the unweathered and weathered sandstones were associated with changes to the clay microstructure upon weathering. The results support the substitution theory that Fe3+ replaces Al3+ in the kaolinite clay component upon weathering. An examination of the impurities present prior to a nonstructural iron removal treatment revealed the presence of minerals that may provide a source of the elements responsible for the substitution process. © 2011 Microscopy Society Of America

Evaluating sustainable intensification and diversification options for agriculture-based livelihoods within an aquatic biodiversity conservation context in Buxa, West Bengal, India

Potential impacts of sustainable intensification and diversification options for agriculture-based livelihoods in Buxa, West Bengal, India were evaluated using bioeconomic modelling. The baseline scenario involved multiple cropping seasons and a combination of crops on 0.9 ha landholdings, livestock husbandry, and exploitation of common property resources. With capital costs of Rs. 128,180 (US$2293) and annual operating costs of Rs. 37,290 (US$ 667), the net benefit generated (excluding depreciation) was Rs. 70,250 (US$1257) annually. The pay-back period was 1.8 years, and the Internal Rate of Return (IRR) was 53.7$ 1,342) and IRR to 56.5% with minimal added costs and risks. Adopting the system of rice intensification (SRI) for paddy cultivation on 0.35 ha increased the IRR to 61.1%, while reducing agrochemical and inorganic fertiliser use. Including small-scale fish culture in a 0.1 ha pond integrated in the irrigation scheme for SRI cultivation resulted in an IRR of 77.3% and reduced the pay-back period to 1.3 years. Some risks to biodiversity are apparent with each scenario; however, with appropriate safeguards, sustainable agricultural intensification and livelihoods diversification could bolster agrobiodiversity and social-ecological resilience of highland communities, while alleviating pressure on biodiversity
