The uses and impact of social and emerging media on public relations practices in Malaysia

Research has shown that social media has been widely discussed among public relations practitioners and scholars in relation to how it has changed public relations practices. A study by Wright and Hinson (2017) revealed that public relations practitioners continue to strongly agree that social and other emerging media technologies have brought dramatic changes to how public relations is practiced in the United States of America. In the Malaysian context, the explosion in social media, especially social networking site such as Facebook, has caused many public relations practitioners to recognise the need to embrace these new media for effective communication with the internal and external audiences. Drawing on Wright and Hinson’s (2016) survey instrument, this study measured the actual use of social and other emerging media by public relations practitioners in Malaysia, and explored its impact on public relations practices. Through a web-based survey, this study found evidence that public relations practitioners in Malaysia have frequently used social media especially Facebook, Instagram and LinkedIn. On average, they spent approximately 26% to 50% of their working time using social and emerging media for public relations and communications activities. The results of this study provide useful insights for academics, researchers and public relations practitioners on how social and emerging media technologies are used in the Malaysian public relations industry

Differences in visual-textual platforms, technical-strategic communication & professionalism vs encroachment between Malaysian & American PR practitioners' social media practices.

Social media platforms and their affordances are found by researchers to affect the public relations (PR) industry and its practitioners’ tasks. Wright and Hinson’s (2015, 2016, 2017) longitudinal studies showed digital media including online social network sites drastically changing the way PR is practised in the United States. This current localised research adapted and modified Wright and Hinson’s quantitative survey instrument to compare Malaysian and American PR professionals’ social media practices. This exploratory study provides comparative insights into the two countries’ PR practitioners’ preference for visual versus textual-based platforms, technical versus strategic perspectives of social media, and professional PR versus encroachment by marketing. The Internet-based survey (N=95; reliability α=0.782) found differences between Malaysian and American PR practitioners in terms of average time spent on social-media based tasks (above—below 50% majority, respectively); types of social-media platforms preferred for PR work— notably Pinterest and Snapchat (Malaysian) versus Twitter and LinkedIn (American); and the department in charge of social media communication— digital/social media and marketing in Malaysia versus communication/PR in the US

A participatory assessment of nitrified urine fertilizer use in Swayimane, South Africa: Crop production potential, farmer attitudes and smallholder challenges

Long-term nutrient mining of soil hampers agricultural production across Africa. However, emerging sanitation technologies afford a hygienically safe and ecologically sustainable solution to this development challenge by providing fertilizers derived from human excreta that could facilitate a socio-technical transition toward a more sustainable food system. To evaluate one such technology, nitrified urine fertilizer (NUF), we conducted participatory action research to assess the potential, from both a biophysical and social perspective, of NUF to serve as a soil fertilizer to support smallholder agricultural production in Swayimane, South Africa. To achieve this objective, we formed a stakeholder group comprised of a cooperative of smallholder farmers, a local NGO (Zimele), and researchers from ETH Zurich and the University of Kwazulu-Natal. Over the course of two growing seasons (2016 and 2017) this stakeholder group assessed the potential of NUF to support smallholder vegetable production (i.e., cabbage). First, we adopted a randomized complete block design incorporating five treatments in season 1 (unfertilized control, nitrified urine, nitrified urine+bone meal, urea, and urea+diammonium phosphate (DAP) and six treatments (unfertilized control, urea, urea+DAP, DAP, nitrified urine, and nitrified urine+DAP) in season 2 to assess cabbage yield and leaf nutrient concentration (sodium, phosphorus, potassium, carbon, nitrogen). Although we observed large variability in yields, the urine-based treatments were as effective as any of the chemical fertilizers. Second, beyond the biophysical analysis, we elicited the challenges and opportunities of the smallholder farmers in our stakeholder group, as well as their attitudes toward the use of NUF as a fertilizer. Through this qualitative work, farmers indicated that their attitudes about the use of NUF as a fertilizer improved and that they would be willing to incorporate this product into their production practices if it was available at scale. Thus, we demonstrate the potential of participatory action research to co-produce knowledge and awareness around an innovative technology. In so doing, we provide evidence that this approach can support a change toward nutrient recycling-based agriculture

Capturing Economic Rents From Resources Through Royalties and Taxes

Oil price fluctuations, concerns over the division of resource revenues, and unconventional oil and gas developments are forcing governments to confront the same issue: how to design optimal royalty and corporate tax systems that bring in a publicly acceptable share of revenues without discouraging private investment. This paper surveys tax and royalty systems across six countries, as well as four US states and five Canadian provinces, offering concise analyses of their strengths and shortcomings to describe the best and simplest approaches to both. As in a public-private partnership, government owns the resources and allows private agents to maximize the rents resources generate. An optimal royalty system will thus be rent-based, ensuring that both owner and agent obtain maximally competitive returns so that each has incentives to continue the partnership. Such a system will also be simple, making compliance easy, manipulation difficult, and risks affordable. And it will be stable, instilling in the private sector the confidence needed to invest for the long term. As for corporate income taxes, they should be neutral across business activities, and applied at equal effective rates on economic income, to avoid distorting market forces through subsidies or needless complexity. A clean rent-based tax that allows all costs incurred by producers to be expensed or carried over, along with a corporate income tax system shorn of many of the preferences that negatively affect business activity, should be the way forward for any government looking to update their fiscal regimes for the 21st century

Chemical evolution of galaxies. I. A composition-dependent SPH model for chemical evolution and cooling

We describe an SPH model for chemical enrichment and radiative cooling in cosmological simulations of structure formation. This model includes: i) the delayed gas restitution from stars by means of a probabilistic approach designed to reduce the statistical noise and, hence, to allow for the study of the inner chemical structure of objects with moderately high numbers of particles; ii) the full dependence of metal production on the detailed chemical composition of stellar particles by using, for the first time in SPH codes, the Qij matrix formalism that relates each nucleosynthetic product to its sources; and iii) the full dependence of radiative cooling on the detailed chemical composition of gas particles, achieved through a fast algorithm using a new metallicity parameter zeta(T) that gives the weight of each element on the total cooling function. The resolution effects and the results obtained from this SPH chemical model have been tested by comparing its predictions in different problems with known theoretical solutions. We also present some preliminary results on the chemical properties of elliptical galaxies found in self-consistent cosmological simulations. Such simulations show that the above zeta-cooling method is important to prevent an overestimation of the metallicity-dependent cooling rate, whereas the Qij formalism is important to prevent a significant underestimation of the [alpha/Fe] ratio in simulated galaxy-like objects.Comment: 19 pages, 22 figures, 2 tables; accepted for publication in MNRA

IDS Based on Bio-Inspired Models

Unsupervised projection approaches can support Intrusion Detection Systems for computer network security. The involved technologies assist a network manager in detecting anomalies and potential threats by an intuitive display of the progression of network traffic. Projection methods operate as smart compression tools and map raw, high-dimensional traffic data into 2-D or 3-D spaces for subsequent graphical display. The paper compares three projection methods, namely, Cooperative Maximum Likelihood Hebbian Learning, Auto-Associative Back-Propagation networks and Principal Component Analysis. Empirical tests on anomalous situations related to the Simple Network Management Protocol (SNMP) confirm the validity of the projection-based approach. One of these anomalous situations (the SNMP community search) is faced by these projection models for the first time. This work also highlights the importance of the time-information dependence in the identification of anomalous situations in the case of the applied methods
