In recent years, influenced by the pervasive power of technology, standards and mandates, Australian hospitals have begun exploring digital forms of keeping this record. The main rationale is the ease of accessing different data sources at the same time by varied staff members. The initial step in this transition was implementation of scanned medical record systems, which converts the paper based records to digitised form, which required process flow redesign and changes to existing modes of work. For maximising the benefits of scanning implementation and to better prepare for the changes, Austin Hospital in the State of Victoria commissioned this research focused on elective admissions area. This structured case study redesigned existing processes that constituted the flow of external patient forms and recommended a set of best practices at the same time highlighting the significance of user participation in maximising the potential benefits anticipated. In the absence of published academic studies focused on Victorian hospitals, this study has become a conduit for other departments in the hospital as well as other hospitals in the incursion.

Full textAbstract:
With a brief description of the physical setting and institutional history of the Australian water sector, this paper reviews the water institutional reforms in Australia focusing especially on the nature and extent of reforms initiated since 1995 and provides a few case studies to highlight the issues and challenges in effecting changes in some key reform components. The reforms initiated in 1995 are notable for their comprehensiveness, fiscal incentives and clear and time-bound targets to be achieved. Although water institutions in Australia have undergone remarkable changes, thanks to the reforms, there are still issues and challenges inherent in reforming maturing water institutions. Regional diversity in legal systems and quality standards as well as conflicts between private interest and public welfare are still serious to constraining market-based water allocation and management. While Australia still needs further reforms, its recent reform experience provides considerable insights into the understanding of both the theory and the practice of water institutional reforms.

Full textAbstract:
Prefabrication has been shown to be an effective way of construction in the modern-day context. Although much progress has been made in developing reinforced concrete (RC), timber and steel prefabricated elements/structures, prefabrication of masonry walling systems has received limited attention in the past. Conventional masonry construction is labour-intensive and time-consuming; therefore, prefabrication can be an effective solution to accelerate the masonry construction to make it more cost-effective. Therefore, in this paper, an attempt has been made to evaluate the effectiveness of prefabricated masonry systems (PMS) in terms of their structural characteristics and sustainability perspectives in an Australian context. Subsequently, the available studies related to PMS and the prospects of developing prefabricated masonry walling systems were appraised and reported. In order to assess the applicability of PMS, a case study was carried out by designing four types of prospective prefabricated masonry walling systems for a typical housing unit in Australia. It was shown that the reinforced (RM), post-tensioned (PT) and thin layered mortared (TLM) masonry systems are better suited for prefabrication. Later, in order to assess the sustainability of the considered masonry walling systems, life cycle energy analyses were carried using the Environmental Performance in Construction (EPIC) database. It was found that there can be nearly 30% and 15% savings, respectively, in terms of energy saving and CO2 emissions in prefabricated construction than the conventional masonry construction. Finally, the prospects of developing PMS and the need for future research studies on these systems are highlighted.

Abstract The identification of extratropical fronts in reanalyses and climate models is an important climate diagnostic that aids dynamical understanding and model verification. This study compares six frontal identification methods that are applied to June and July reanalysis data over the Central Wheatbelt of southwest Western Australia for 1979–2006. Much of the winter rainfall over this region originates from frontal systems. Five of the methods use automated algorithms. These make use of different approaches, based on shifts in 850-hPa winds (WND), gradients of temperature (TGR) and wet-bulb potential temperature (WPT), pattern matching (PMM), and a self-organizing map (SOM). The sixth method was a manual synoptic technique (MAN). On average, about 50% of rain days were associated with fronts in most schemes (although methods PMM and SOM exhibited a lower percentage). On a daily basis, most methods identify the same systems more than 50% of the time, and over the 28-yr period the seasonal time series correlate strongly. The association with rainfall is less clear. The WND time series of seasonal frontal counts correlate significantly with Central Wheatbelt rainfall. All automated methods identify fronts on some days that are classified as cutoff lows in the manual analysis, which will impact rainfall correlations. The front numbers identified on all days by the automated methods decline from 1979 to 2006 (but only the TGR and WPT trends were significant at the 10% level). The results here highlight that automated techniques have value in understanding frontal behavior and can be used to identify the changes in the frequency of frontal systems through time.

Full textAbstract:
Transit agencies increasingly deploy planning strategies to improve service reliability and real-time operational control to mitigate the effects of travel time variability. The design of such strategies can benefit from a better understanding of the underlying causes of travel time variability. Despite a significant body of research on the topic, findings remain influenced by the approach used to analyze the data. Most studies use linear regression to characterize the relationship between travel time reliability and covariates in the context of central tendency. However, in many planning applications, the actual distribution of travel time and how it is affected by various factors is of interest, not just the condition mean. This paper describes a quantile regression approach to analyzing the impacts of the underlying determinants on the distribution of travel times rather than its central tendency, using supply and demand data from automatic vehicle location and farecard systems collected in Brisbane, Australia. Case studies revealed that the quantile regression model provides more indicative information than does the conditional mean regression method. Moreover, most of the coefficients estimated from quantile regression are significantly different from the conditional mean–based regression model in terms of coefficient values, signs, and significance levels. The findings provide information related to the impacts of planning, operational, and environmental factors on speed and its variability. On the basis of this information, transit designers and planners can design targeted strategies to improve travel time reliability effectively and efficiently.

Australian Journal of Experimental Agriculture 43, no. 3 (2003): 205. http://dx.doi.org/10.1071/ea01012.
Full textAbstract:
During the last decade, a range of indicators has been advocated for assessing soil, farm and catchment health. This paper assembles some recent experiences of the authors in developing and using indicators from paddock to national scales. Indicators are merely a subset of the attributes that are used to quantify aspects of catchment or farm health. Their selection and use in the past has led to criticism of indicators, but, given an explicit approach, most of the criticisms can be overcome. Reliable indicators provide positive and negative signals about the current status of natural resources and how these properties have changed over time. They are used both to identify potential risks and to confirm that current farming practices and systems of land use are effective in maintaining the resource base or economic status. They should be precursors for change and future on-ground investments when problems are observed or identified.A structured approach is needed to ensure indicators are selected and used efficiently. This approach involves: deciding local issues and selecting the most appropriate indicators to reflect those issues; interpreting both positive and negative signals from the monitoring process; taking appropriate action to resolve problems; and, using indicators to monitor the outcomes from the action taken.Finally, we have drawn on these and other experiences to compile a list of indicators that may be used to address sustainability issues associated with farm productivity, soil health and catchment health identified in recent strategic plans developed for the northern grains region of Australia, the focus of this special journal issue.

Full textAbstract:
Changes in the farm operating and policy environments and a need to remain profitable under a cost-price squeeze have contributed to dairy systems in Australia and New Zealand becoming more intensive and complex in recent decades. Farm systems in both countries are now diverse, varying from being based predominantly on pasture with little purchased supplements, to those dependent on high levels of feed supplements and even having zero grazing. Dairy farm performance (defined in this paper as production or technical performance), return (return on assets or profit) and risk (variation in economic performance over time), and intensity of dairy systems was examined using farm survey data, case studies and existing published studies. The level of single technical performance measures, such as milk production, feed conversion efficiency and pasture consumption, prevailing in a business are not guides to the operating profit and return on assets of a business. In addition, when survey data of farm performance was grouped by return on assets, few farms were in the top 25% in successive years. Farms that performed consistently well were characterised by good, but not extreme, technical performance in a range of key areas, which translated to favourable business return (return on asset and profit). The knowledge and skills of farm managers are critical, and means that many different dairy systems can perform well physically and financially and successfully meet farmer goals. The relation between risk and the intensity of dairy systems was also investigated. Options that intensified systems generally resulted in higher net wealth for the farm owner, but almost always at increased risk. The best system for any farmer to operate is one which best meets their multifaceted preferences and goals, regardless of system type.

"Impact of Technical, Human, and Organizational Risks on Reliability of Fire Safety Systems in High-Rise Residential Buildings—Applications of an Integrated Probabilistic Risk Assessment Model." Applied Sciences 10, no. 24 (December 14, 2020): 8918. http://dx.doi.org/10.3390/app10248918.
Full textAbstract:
The current paper presents an application of an alternative probabilistic risk assessment methodology that incorporates technical, human, and organizational risks (T-H-O-Risk) using Bayesian network (BN) and system dynamics (SD) modelling. Seven case studies demonstrate the application of this holistic approach to the designs of high-rise residential buildings. An incremental risk approach allows for quantification of the impact of human and organizational errors (HOEs) on different fire safety systems. The active systems considered are sprinklers, building occupant warning systems, smoke detectors, and smoke control systems. The paper presents detailed results from T-H-O-Risk modelling for HOEs and risk variations over time utilizing the SD modelling to compare risk acceptance in the seven case studies located in Australia, New Zealand, Hong Kong, Singapore, and UK. Results indicate that HOEs impact risks in active systems up to ~33%. Large variations are observed in the reliability of active systems due to HOEs over time. SD results indicate that a small behavioral change in ’risk perception’ of a building management team can lead to a very large risk to life variations over time through the self-reinforcing feedback loops. The quantification of difference in expected risk to life due to technical, human, and organizational risks for seven buildings for each of 16 trial designs is a novel aspect of this study. The research is an important contribution to the development of the next generation building codes and risk assessment methods.

Full textAbstract:
The large number of wells associated with typical coal seam gas (CSG) developments in Australia has changed the paradigm for field management and optimisation. Real time data access, automation and optimisation—which have been previously considered luxuries in conventional resources—are key to the development and operation of fields, which can easily reach more than 1,000 wells. The particular issue in Australia of the shortage of skilled labour and operators has increased pressure to automate field operations. This extended abstract outlines established best practices for gathering the numerous data types associated with wells and surface equipment, and converting that data into information that can inform the decision processes of engineers and managers alike. There will be analysis made of the existing standard, tools, software and data management systems from the conventional oil and gas industry, as well as how some of these can be ported to the CSG fields. The need to define industry standards that are similar to those developed over many years in the conventional oil and gas industry will be discussed. Case studies from Australia and wider international CSG operations will highlight the innovative solutions that can be realised through an integrated project from downhole to office, and how commercial off the shelf solutions have advantages over customised one-off systems. Furthermore, case studies will be presented from both CSG and conventional fields on how these enabling technologies translate into increased production, efficiencies and lift optimisation and move towards the goal of allowing engineers to make informed decisions as quickly as possible. Unique aspects of CSG operations, which require similarly unique and innovative solutions, will be highlighted in contrast to conventional oil and gas.

Full textAbstract:
Protected areas remain a cornerstone for global conservation. However, their effectiveness at halting biodiversity decline is not fully understood. Studies of protected area benefits have largely focused on measuring their impact on halting deforestation and have neglected to measure the impacts of protected areas on other threats. Evaluations that measure the impact of protected area management require more complex evaluation designs and datasets. This is the case across realms (terrestrial, freshwater, marine), but measuring the impact of protected area management in freshwater systems may be even more difficult owing to the high level of connectivity and potential for threat propagation within systems (e.g. downstream flow of pollution). We review the potential barriers to conducting impact evaluation for protected area management in freshwater systems. We contrast the barriers identified for freshwater systems to terrestrial systems and discuss potential measurable outcomes and confounders associated with protected area management across the two realms. We identify key research gaps in conducting impact evaluation in freshwater systems that relate to three of their major characteristics: variability, connectivity and time lags in outcomes. Lastly, we use Kakadu National Park world heritage area, the largest national park in Australia, as a case study to illustrate the challenges of measuring impacts of protected area management programmes for environmental outcomes in freshwater systems.

The international environment today has been undergoing unprecedented change and many companies are seeking new ways to stand out from the competition by sustaining their competitive advantage. Internationalization and firms’ consolidation increase competition in the dynamic marketplace .Companies are no longer staying competitive simply through focusing on product quality and pricing as customers are becoming more high-demanding related to customer service offer. This issue directs the companies’ main focus today to address the customer needs in the ever-changing environment.In order to be the winners in the marketplace, timing and superior customer service are becoming the keys to attain competitive advantage for a company. Time-based competition is an important issue that many companies are facing currently as customers are becoming more time-sensitive and time-oriented in terms of better services, reliability and delivery. To keep up with the changes in demand from customers, it is important to satisfy customers’ objectives and needs in order to provide superior customer service, thus, establish good relationship with them. In the ever-changing and dynamic business environment company needs to adapt and exploit the changes in order to meet the new challenges in the marketplace. It is crucial for the company to respond to changing needs of existing customers and seeking to serve new customers externally. The ways to renew the customers’ services and how they are delivered are critical capabilities for many companies to acquire nowadays. This leads to increasing interaction between marketing and logistics where logistics is considered a platform for supporting new strategic moves on the market.This master thesis originates from a need to research the links between customer service improvement and Just-in-time distribution in order to sustain competitive advantage. We propose to extend the Just-In-Time concept to incorporate a customer perspective, which results in changes the warehousing, ordering and delivering routines. Subsequently, this creates timing ability as well as coordination of information and material flows through timely decisions, which are difficult for competitors to emulate. Based on our analysis and conclusion, companies are recommended to shift from the traditional production-oriented to market-oriented focuses through incorporation of customers' perspective into the value chain. To deploy this, companies should start from the customer end and understand customers' needs and establish mutual beneficial relationships with customers. Long-lasting business relationships ultimately determine the success of the company. Furthermore, we conclude that successful learning to change the routines requires time for the transformation of traditional delivery practice to perform direct deliveries activities. They are based on the common understanding of the tasks and rules as well as common codes of internal coordination processes.

Since their introduction to the United States from Japan in the 1980s, inter-organizational cooperation practices between buyers and suppliers have provided lower costs, shorter development and production cycles, and higher levels of quality and productivity. Many studies of interorganizational cooperation have relied on transaction cost economicsframeworks,which ignore cultural differences. Few studies have analyzed inter-organizational cooperation in Mexico, a less-developed country (LDC) with a cultural and industrial environment differentfromthe U.S. This study is concerned with the influence of interorganizational trust, individualism and collectivism (indcol), and the superordinate goal ofjust-in-time/total quality management (JIT/TQM) on inter-organizational cooperation.

<p>This chapter presents a number of case studies that deal with the service design of composite steel-concrete buildings associated with the time-dependent behaviour of the concrete. The particular focus of this chapter is to outline key design aspects that need to be accounted for in design and that are influenced by concrete time effects. The first case study provides an overview of the design considerations related to the time-dependent column shortening in typical multi-storey buildings by considering the layout of the Intesa Sanpaolo Headquarters in Turin as reference. The second case study focuses on a composite floor of a commercial building constructed in Australia and it provides an overview of the conceptual design used to select the steel beam framing arrangement to support the composite floor system while accounting for concrete cracking and time effects. The third case study deals with the Quay Quarter Tower that has been designed for the repurposing of an existing 50-year old building in Australia while accounting for the time-dependent interaction between the existing and the new concrete components of the building.</p>

In modern organisations a large portion of senior management’s time is now being spent on finding ways to measure the contribution of their organisations’ IS/IT investments to business performance. It has been shown that IS/IT investments in many organisations are huge and increasing rapidly every year and yet there is still a lack of understanding of the impact of the proper IS/IT investment evaluation processes and practices in these organisations. At the same time, the issue of expected and actual benefits realised from IS/IT investments has also generated a significant amount of debate in the IS/IT literature amongst the researchers and practitioners. This is as true in Australia as it is in the rest of the developed world. Thus, one can argue that a detailed program of research into the current practice and process of IS/IT investment evaluation in Australia is warranted. This paper reviews the progress made in research in this area and proposes a research program incorporating surveys, case studies, and expert focus groups to assess current practice and to develop an approach, model or framework based on the fit between theory and practice of IS/IT investment evaluation by large Australian organisations.

Studies of Australian and Amazonian languages have demonstrated the existence of an associated motion function. Chapter 11 demonstrates that associated motion is just one of the possible outcomes of the emergence of new functions. The associated action may involve activities other than motion. This associated activity is called here ‘compositional action’. This function emerged as a result of the presence of the rich system of verbal inflectional markers coding directionality and spatial orientation in the languages considered. The importance of this chapter is that it demonstrates that a rich inflectional coding on a lexical category - in this case the verb - allows for the emergence of a new type of function and not merely provides a new locus of coding. The implications of this conclusion, which supports previous studies of Australian, Amazonian, and Slavic languages, is that it calls for a new typology of functions.

The Australian Catholic University (ACU National at www.acu.edu.au) is a public university funded by the Australian Government. There are six campuses across the country, located in Brisbane, Queensland; North Sydney, New South Wales; Strathfield, New South Wales; Canberra, Australian Capital Territory (ACT); Ballarat, Victoria; and Melbourne, Victoria. The university serves a total of approximately 27,000 students, including both full- and part-time students, and those enrolled in undergraduate and postgraduate studies. Through fostering and advancing knowledge in education, health, commerce, the humanities, science and technology, and the creative arts, ACU National seeks to make specific and targeted contributions to its local, national, and international communities. The university explicitly engages the social, ethical, and religious dimensions of the questions it faces in teaching, research, and service. In its endeavors, it is guided by a fundamental concern for social justice, equity, and inclusivity. The university is open to all, irrespective of religious belief or background. ACU National opened its doors in 1991 following the amalgamation of four Catholic tertiary institutions in eastern Australia. The institutions that merged to form the university had their origins in the mid-17th century when religious orders and institutes became involved in the preparation of teachers for Catholic schools and, later, nurses for Catholic hospitals. As a result of a series of amalgamations, relocations, transfers of responsibilities, and diocesan initiatives, more than twenty historical entities have contributed to the creation of ACU National. Today, ACU National operates within a rapidly changing educational and industrial context. Student numbers are increasing, areas of teaching and learning have changed and expanded, e-learning plays an important role, and there is greater emphasis on research. In its 2005–2009 Strategic Plan, the university commits to the adoption of quality teaching, an internationalized curriculum, as well as the cultivation of generic skills in students, to meet the challenges of the dynamic university and information environment (ACU National, 2008). The Graduate Diploma of Education (Secondary) Program at ACU Canberra Situated in Australia’s capital city, the Canberra campus is one of the smallest campuses of ACU National, where there are approximately 800 undergraduate and 200 postgraduate students studying to be primary or secondary school teachers through the School of Education (ACT). Other programs offered at this campus include nursing, theology, social work, arts, and religious education. A new model of pre-service secondary teacher education commenced with the introduction of the Graduate Diploma of Education (Secondary) program at this campus in 2005. It marked an innovative collaboration between the university and a cohort of experienced secondary school teachers in the ACT and its surrounding region. This partnership was forged to allow student teachers undertaking the program to be inducted into the teaching profession with the cooperation of leading practitioners from schools in and around the ACT. In the preparation of novices for the teaching profession, an enduring challenge is to create learning experiences capable of transforming practice, and to instill in the novices an array of professional skills, attributes, and competencies (Putnam & Borko, 2000). Another dimension of the beginning teacher experience is the need to bridge theory and practice, and to apply pedagogical content knowledge in real-life classroom practice. During the one-year Graduate Diploma program, the student teachers undertake two four-week block practicum placements, during which they have the opportunity to observe exemplary lessons, as well as to commence teaching. The goals of the practicum include improving participants’ access to innovative pedagogy and educational theory, helping them situate their own prior knowledge regarding pedagogy, and assisting them in reflecting on and evaluating their own practice. Each student teacher is paired with a more experienced teacher based at the school where he/she is placed, who serves as a supervisor and mentor. In 2007, a new dimension to the teaching practicum was added to facilitate online peer mentoring among the pre-service teachers at the Canberra campus of ACU National, and provide them with opportunities to reflect on teaching prior to entering full-time employment at a school. The creation of an online community to facilitate this mentorship and professional development process forms the context for the present case study. While on their practicum, students used social software in the form of collaborative web logging (blogging) and threaded voice discussion tools that were integrated into the university’s course management system (CMS), to share and reflect on their experiences, identify critical incidents, and invite comment on their responses and reactions from peers.

Full textAbstract:
The spectral modeling approach to numerical weather prediction is being practiced in many parts of the world. Historically, the spectral approach came into atmospheric sciences from studies of geomagnetism, where it was introduced by Elsasser in the late nineteenth century. The first attempt of spectral representation of data sets and its use via simple vorticity conserving models came in the 1940s. The works of Neamtan (1946) from the University of Manitoba and Haurwitz (1940) and Craig (1945) from New York University were pioneering during this era. These were still close to linear problems, lacking any formalism for addressing the nonlinear advective dynamics. It was in the late 1950s when we saw the emergence of formal proposals for the solution of the nonlinear barotropic vorticity equation. Pioneering work from the University of Chicago (Platzman 1960; Baer 1964) explored what is sometimes called the interaction coefficients approach for the nonlinear problem. Around the same time at MIT we saw the elucidation of what are now called the low-order systems. This pioneering work of Lorenz (1960b) and Saltzman (1959) brought to us the first exposure to simple nonlinear systems and the concept of chaos. These simple three-component systems demonstrated some of the essentials of nonlinear dynamics and the growth of errors arising from initial state uncertainties. The interaction coefficients approach to the solution of the weather forecast problem led to unmanageably large memory requirements that were not easily amenable to the then available, or even to the present, memory of computers. It was during the mid-1950s when the Cooley-Tukey algorithm (1965) emerged and provided a breakthrough via the fast Fourier transform. This was exploited and demonstrated to provide accurate representations of the quadratic terms for fast computation of the nonlinear advective dynamics by contributions from Eliasen et al. (1970) and Machenhauer (1974) from the University of Copenhagen and from Orszag (1970) at MIT. Thereafter, we saw a rapid development of global spectral models in many parts of the world, especially Australia, Canada, England, Japan, and the United States.

Full textAbstract:
The long history of research at the Jornada Basin (through the Agricultural Research Service [ARS] since 1912, New Mexico State University in the late 1920s, and joined by the Long-Term Ecological Research [LTER] program in 1981) has provided a wealth of information on the dynamics of arid and semiarid ecosystems. However, gaps in our knowledge still remain. One of the most perplexing issues is the variation in ecosystem dynamics across landscapes. In this concluding chapter to this volume, we propose a new conceptual model of arid and semiarid landscapes that focuses explicitly on the processes and properties that generate spatial variation in ecosystem dynamics. We also describe how our framework leads to future research directions. Many studies have documented variable rates and patterns of shrub invasion at the Jornada as well as at other semiarid and arid regions of the world, including the Western United States, northern Mexico, southern Africa, South America, New Zealand, Australia, and China (York and Dick-Peddie 1969; Grover and Musick 1990; McPherson 1997; Scholes and Archer 1997; see also chapter 10). In some cases, shrub invasion occurred very rapidly: At the Jornada, areas dominated by perennial grasses decreased from 25% to < 7% from 1915 to 1998 with most of this conversion occurring prior to 1950 (Gibbens et al. 2005; Yao et al. 2002a). In other cases, shrub invasion occurred slowly, and sites were very resistant to invasion; for example, perennial grasses still dominate on 12 out of 57 research quadrats originally established in black grama (Bouteloua eropoda) grasslands in the early twentieth century (Yao et al. 2002b). Soil texture, grazing history, and precipitation patterns are insufficient to account for this variation in grass persistence through time (Yao et al. 2002a). It is equally perplexing that although many attempts to remediate these shrublands back to perennial grasses have led to failure, some methods worked well, albeit with long (> 50 year) time lags (Rango et al. 2002; see also chapter 14). Although variations in vegetation dynamics and shrub invasion are the most well known, other lesser known aspects of arid and semiarid systems have been found to be quite variable as well.

Governments provide a wide range of services, and the digital economy provides both threats and opportunities in this sector. The Transport Accident Commission (TAC) is a compulsory, government owned and operated insurance scheme for third-party, no-fault liability insurance for transport accident victims, operated in Victoria, Australia. E-business has now been widely used in all sectors from small business (Loane, McNaughton, & Bell, 2004) to emerging economies (Li & Chang, 2004), and in very different industry sectors (Cagno, Di Giulio, & Trucco, 2004; Golden, Hughes, & Gallagher, 2003). Major steps forward and applications have occurred in retailing (Leonard & Cronan, 2003; Mackay, Altmann, & McMichael, 2003; Starr, 2003). Applications need to be highly customized as the business-to-consumer (B2C) and business-to-business (B2B) environments are very different, and requirements of industries such as retailing and mining, and indeed government, differ substantially (Carter, 2003; He & Lung, 2002; Rotondaro, 2002). Government provides a particularly different environment for e-business applications because government services are often delivered in monopoly circumstances, with no real profit motive behind them. At the height of the technology boom in October 1999, Tony Marxsen joined the TAC as head of IT to develop a new IT outsourcing contract for the organization as the current 5-year contract was due to end in July 2000. He quickly realized that the TAC IT systems were out of date, lacked IT process integration, and were constraining improvement in business processes, and that no significant investments had been made for some time. Renewing or redesigning the outsourcing contract, the basis for which he had been employed, would only be a short-term solution. The problem was that the cost of new infrastructure would be high, and return on technology investment would mainly be realized from redesigned business processes enabled by the new technology. Tony wanted to propose a business transformation, with process changes as well as significant investment in IT infrastructure. Together, these would take the TAC from 1970s technology into the 21st century. The problem was that their (investments in such transformation) payoffs are not easily and quickly achieved. Their value does not come from installing the technology; it comes from changing both operating and management processes—perhaps operating and managing cultures too. (Ross & Beath, 2002, p. 53) Tony knew he would have to win the support of the board and senior management, but he could not immediately give them a concrete business case for the investment. He also knew that any infrastructure investment had to be linked with a major process-improvement initiative from the start to avoid the double investment of building new applications to support old processes, and then undertaking major modifications or even replacement when the need for improvement became obvious to the board and management team. He compared investing in IT infrastructure to rewiring and replumbing your house: as far as visitors are concerned, there’s no visible difference, everything’s behind the walls, but as the owner you get the benefits of things like cheaper electricity and water bills because of efficiencies in the new redesigned systems. The problem is convincing people that they will get these results in the future, but that they need to hand over the money now, when there’s no hard evidence for the benefits they’ll get, just a bunch of assumptions and no guarantees. It’s a big ask for any Board. (Marxsen, personal communication, September 4, 2003) Tony knew that the first hurdle he would have to overcome would be getting the board to agree to give him the opportunity to put together a team to develop a business case for the board’s further consideration.

Full textAbstract:
Gas production flowlines are presenting flow assurance challenges in hydrate management resulting from low ambient seawater temperatures in an increasing number of deepwater developments. During operation the equilibrium hydrate temperature of the produced fluid may be above the minimum seabed temperature, and hence there is a risk of hydrate blockage in the subsea system should the hydrate inhibition system fail. The continuous injection of MEG, with little or no insulation of the subsea system, is a common hydrate mitigation strategy for a gas production system. If insufficient inhibitor is injected there is a risk of hydrates forming and potential blockage of the pipeline in parts of the field. The industry-preferred approach for hydrate blockage remediation is Dual Sided Depressurisation (DSD). The objective is to depressurise the flowline to below hydrate onset conditions, allowing hydrate dissociation and safely disposing of the gas inventory. This is typically performed by one of two methods; installation of a dual flowline system for facility based depressurisation (with CAPEX implications); or a Mobile Offshore Drilling Unit (MODU) can be connected to an appropriate point upstream of the blockage to allow simultaneous depressurisation at the MODU and the facility (with OPEX implications). It is recognised that either method incurs significant costs. Typically the cost and time uncertainties of bringing in a MODU to solve these production stoppages is unattractive. Consequently subsea gas developments have often incurred the increased CAPEX of providing dual flowlines to permit DSD from the facility. An optimisation of the MODU-based intervention method is the subject of this paper. The feasibility of using a “lightweight” intervention vessel (for example an Offshore Support Vessel) in place of the MODU to depressurise the flowline is discussed. This paper discusses hydrate remediation difficulties and case studies; presents emerging hydrate remediation methods and briefly introduces vessel requirements. In discussing this optimisation, this paper also presents an introduction to hydrate remediation theory, some practical challenges, case studies and vessel requirements. The study concluded: • Significant CAPEX reductions may be achieved by adopting the outlined strategy; namely avoiding dual flowline infrastructure, and ensuring a reduced response time and day rate for any hydrate remediation operations to be performed. • For this strategy to be adopted cost effectively, pre-engineering, along with suitable contractual arrangements, are required to make the necessary equipment and personnel resources readily available should a hydrate blockage occur. For assets in remote locations, e.g. Australia, making the resources available is a significant challenge. • Flowline system access for depressurisation may be achieved by two methods; via the subsea Christmas tree or via suitably located fluid injection/vent access point(s).

Abstract There is a significant drive to decarbonise the energy system resulting in a need to integrate large quantities of intermittent renewable power into both onshore consumer grids and offshore isolated grids. This brings significant technical challenges that can be addressed using the right energy storage technology for future times of intermittency and peak power demands. The innovative Repurposed Offshore Pipelines as Energy Storage (ROPES) solution repurposes existing, aged offshore installations into energy storage systems based on proven hydro-pneumatic principles, towards a cost-competitive, highly reliable system. Findings from a recent Concept Assess study prove the cost competitiveness of the solution, thanks to alow Levelised Cost of Storage (LCOS), paired with the value of deferring full decommissioning of existing assets. The study scope covers aspects of market recognition, technical feasibility, risk and opportunity assessment, cost estimates and value delivery to potential clients. Four case studies covering potential prospects offshore Australia and in the North Sea illustrate the diverse architectural application of the solution. The resultant cost estimates form the NPV analysis, and eventually derive the solution LCOS, which shows cost superiority over marinised Li-ion batteries and is comparable to onshore battery systems. The solution shows clear benefits over a typical battery storage system, including reduced safety risks, less topside constraints along with a longer and predictable operating lifetime. The ROPES solution enables the storage of renewable power whilst allowing to optimise time and expenditure for decommissioning of existing infrastructure, therefore represents a unique opportunity to unlock a new market segment within the offshore energy sector.

Full textAbstract:
Abstract Multilateral wells have been proven over decades and have developed into a reliable and cost effective approach to mature field rejuvenation and extended commercial viability. This paper will discuss case studies demonstrating a number of techniques used to create infill multilateral wells in existing fields with a high level of reliability and repeatability. Techniques reviewed will cover cutting and pulling production casing to drill and case a new mainbore versus sidetracking and adding laterals to an existing mainbore. Discussion will also cover completion designs that tie new laterals into existing production casing providing significantly greater reservoir contact. Temporary isolation of high water-cut laterals brought into production later in the well's life through bespoke completion designs will also be discussed. Case studies will include discussion of workover operations, isolation methods, and lateral creation systems. Where available, resulting field performance improvements will also be discussed. In Norway, slot recoveries are commonly performed by cutting and pulling the 10-3/4" casing, redrilling a new mainbore, and running new casing. This enables junction placement closer to unswept zones and easier lateral drilling to targets. It does have drawbacks, however, related to the additional time required to pull the subsea xmas tree and challenges associated with pulling casing. In 2019, Norway successfully completed a 10-3/4" retrofit installation, whereas a sidetrack was made from the 10-3/4" and an 8-5/8" expandable liner was run down into the reservoir pay zone where two new laterals were created. The 8-5/8" liner saved time otherwise spent having to drill the section down to the payzone from the laterals. These wells have a TAML Level 5 isolated junction, Autonomous Inflow Control Devices (AICDs) in each lateral, and an intelligent completion interface across the junction, enabling active flow management and monitoring of both branches. In Asia, infill laterals were added to existing wellbores by sidetracking 9-5/8" casing and tying production back to the original mainbore. These dual laterals were completed with intelligent completions to enable lateral flow management and monitoring of both laterals. In Australia, dual laterals were created in a similar fashion; laterals are added to existing wells; however, a novel approach was used to manage water from existing lower mainbore laterals whereby they are shut in at completion and opened later when the new lateral is watered out. The older lateral now produces at lower water cut given the time allowed for water coning in the lateral to relax. Using this practice, production is alternated back and forth between the two laterals. In the Middle East, an older well has been converted from TAML Level 4 to Level 5 in order to prevent detected gas migrating into the mainbore at the junction. This conversion of a cemented junction well has enabled production to resume on this well. The well was converted to incorporate an intelligent completion to enable flow control of each lateral. This paper intends to provide insights into the various mature field re-entry methods for multilateral well construction, and a review of the current technology capabilities and well designs through the review of multiple case histories.

Abstract There is a significant drive to decarbonise the energy system resulting in a need to integrate large quantities of intermittent renewable power into both onshore consumer grids and offshore isolated grids. This brings significant technical challenges that can be addressed using the right energy storage technology for future times of intermittency and peak power demands. The PowerBundle is a full-scale subsea hydro-pneumatic energy storage (HPES) system. Electricity is used to pump seawater into a closed pipeline bundle to compress a volume of pre-charged air and is then recovered by allowing the compressed air to push the water back out through a hydraulic turbine generator. The surrounding seawater acts as a natural heatsink, avoiding thermal losses and making the solution highly energy efficient. At the heart of the development is an established supply-chain, developed over 40 years, which will deliver a reliable system with an up to 40-year service lifetime, independent of the charging-discharging regime. The system avoids any harmful chemicals and embodies the core principles of safety, reliability, sustainability and cost-effectiveness. This HPES solution will be attractive for offshore projects requiring an interface to provide power balancing and scheduling, which will benefit stakeholders in the oil-and-gas and renewable energy sectors seeking to deliver intermittent power to their end customer. This development will lead to a significant reduction of greenhouse gas (GHG) emissions due to more holistic renewable infrastructure. The PowerBundle provides a scalable storage solution which can be placed in waters close to land, supporting the scale-up, resilience and economies of renewable electricity. However, as a first step, the innovative Repurposed Offshore Pipelines as Energy Storage (ROPES) solution repurposes existing, aged offshore installations into energy storage systems based on proven hydro-pneumatic principles, towards a cost-competitive, highly reliable system. Findings from a recent Concept Assess study prove the cost competitiveness of the solution, thanks to a low Levelised Cost of Storage (LCOS), paired with the value of deferring full decommissioning of existing assets.

Full textAbstract:
There is increasing pressure on the pipeline industry to be able to demonstrate that its asset management and engineering capability management are at a satisfactory level. This is needed to give policymakers, regulators and industry stakeholders confidence in the safety and environmental sustainability of petroleum pipelines. Regulators, in particular, are seeking assurance from pipeline owner/operators that they have capable pipeline engineers designing, constructing, operating and maintaining petroleum pipelines. At present, there are no generally accepted approaches to recognising and developing pipeline engineering capability. The paper will discuss three levels of capability recognition as: (1) registration – as pipeline engineers (not just in mechanical, civil or chemical engineers (overall standing level)) – (2) qualification (sub-discipline/job level) and (3) competency (task level). The most granular and useful of these is competency. This is because it is at the level that is most immediate: the task at hand. Competency, the combination of knowledge and experience that leads to expertise, is increasingly seen as the best practice basis for learning, particularly for professionals. Significantly, once competencies have been defined in competency standards, they can become the building blocks used to define the requirements for both registration and qualification. The Australian Pipelines and Gas Association (APGA) has developed a comprehensive competency system for both onshore and offshore sectors. There are 226 onshore competency standards and 57 offshore competency standards describing, in a succinct format, what is required to be competent. The succinct format of the competency standards avoids the pitfalls of many other systems of competency description, providing enough information to be clear about what is required without unnecessary complexity. In addition to the detailed competency standards, the competency system has tools, resources and a progressive rating scale that make competency standards accessible and easily used. The competency system is characterised by such flexibility that, to date, APGA has identified 15 applications, all of which will add value to engineers and the companies that employ them. The paper will explain, in detail, APGA’s Pipeline Engineer Competency System, how it works and how it can provide the building blocks for a wide range of tasks that support the training, development and recognition of pipeline engineers’ capabilities, including defining the requirements for registration and qualification. The paper will provide case studies, based on the APGA Competency System, showing how it can be used to create requirements for qualifications and registration and to design in-house training and development plans.

Full textAbstract:
Abstract Methane (CH4) is a potent greenhouse gas, responsible for at least a quarter of Today's global warming. Thus, reducing CH4 emissions from global oil and gas infrastructure represents a key opportunity to significantly slow the rate of climate change—with several recent studies highlighting that readily available and cost-effective technologies can reduce a large fraction of current emissions from this industry. Operators have announced ambitious pledges to reduce CH4 emissions from the oil and gas supply chain. For these targets to be effective, it is critical to improve the understanding in terms of how much methane emitted, identify where it is being emitted, and to empirically track progress as mitigation strategies are implemented. Here, we have synthesized results from recent multi-scale scientific studies across geographies (i.e., North America, Europe, Australia), highlighting the role of empirical data in improving emission reporting, and guiding mitigation action. We illustrate how emissions data collected at different spatial and temporal scales can be integrated to provide a clear characterization across the different segments of the oil and gas supply chain. Measurement-based approaches are now being successfully implemented, and the integration and reconciliation of data at different scales can provide useful information to reduce the uncertainty in terms of magnitude and location of emissions. As more operators incorporate these approaches and compile improved emissions data, it will be plausible to improve equipment and system design, perform root cause analysis and reduce the frequency of large emission events. Measurement-based CH4 emissions data is essential to an efficient and effective implementation of CH4 mitigation strategies. This paper highlights how a diversity of robust measurement approaches can be deployed in concert—further identifying mitigation opportunities and tracking changes in emissions over time.

The global Business Intelligence (BI) market grew by 10% in 2013 according to the Gartner Report. BI has been the top implementation priority for organizations for many years now. Today organizations require better use of data and analytics to support their business decisions. Internet power and business trend changes have provided a broad term - Big Data. To be able to handle it and leverage a value of having access to Big Data, organizations have no other choice than to get proper systems implemented and working. However traditional methods are not efficient for changing business needs. Long time between project start and go-live causes a gap between initial solution blueprint and actual user requirements in the end of the project. This article presents the latest market trends in BI systems implementation by comparing Agile with traditional methods. It presents a case study provided in a large telecommunications company (20K employees) and the results of a pilot research provided in the three large companies telecommunications, digital and insurance. Both studies prove that Agile methods might be more effective in BI projects from an end-user perspective and give first results and added value in a much shorter time compared to a traditional approach. Organizations often do not have a clear vision of BI requirements. Thus users ask for changes just before a BI product readiness, which Agile ensures in contradiction to traditional methods.

Full textAbstract:
Tension metastable fluid states offer unique potential for leap-ahead advancements in radiation detection. Such metastable fluid states can be attained using tailored resonant acoustics to result in acoustic tension metastable fluid detection (ATMFD) systems. ATMFD systems are under development at Purdue University. Radiation detection in ATMFD systems is based on the principle that incident nuclear particles interact with the dynamically tensioned fluid wherein the intermolecular bonds are sufficiently weakened such that even fundamental particles can be detected over eight orders of magnitude in energy with intrinsic efficiencies far above conventional detection systems. In the case of neutron-nuclei interactions the ionized recoil nucleus ejected from the target atom locally deposits its energy, effectively seeding the formation of vapor nuclei that grow from the sub-nano scale to visible scales such that it becomes possible to record the rate and timing of incoming radiation (neutrons, alphas, and photons). Nuclei form preferentially in the direction of incoming radiation. Imploding nuclei then result in shock waves that are readily possible to not only directly hear but also to monitor electronically at various points of the detector using time difference of arrival (TDOA) methods. In conjunction with hyperbolic positioning, the convolution of the resulting spatio-temporal information provides not just the evidence of rate of incident neutron radiation but also on directionality — a unique development in the field of radiation detection. The development of superior intrinsic-efficiency, low-cost, and rugged, ATMFD systems is being accomplished using a judicious combination of experimentation-cum-theoretical modeling. Modeling methodologies include Monte-Carlo based nuclear particle transport using MCNP5, and also complex multi-dimensional electromagneticcum-fluid-structural assessments with COMSOL’s Multi-physics simulation platform. Benchmarking and qualification studies have been conducted with Pu-based neutron-gamma sources with encouraging results. This paper summarizes the modeling-cum-experimental framework along with experimental evidence for the leap-ahead potential of the ATMFD system for transformation impact on the world of radiation detection.

Full textAbstract:
Abstract With the paradigm shift towards digitalization, Operators and service providers are inclined to use technologies that can optimize efforts from workforce by providing meaningful information rather than ‘just’ data, transition subject matter knowledge into machines rather than limiting to people, deploy machine learning techniques to improve systems and leverage this big data to serve on wide scale. Historically, condition monitoring knowledge has primarily been people-centric and Reliability personnel have to spend hours in front of screen reviewing terabytes of data. Unfortunately, most of the time is spent to find problems rather than finding solutions. Need of the hour is to define automated mechanisms for triggering alerts pointing towards developing malfunctions for which systems are created with embedded knowledge to run the data through pre-configured diagnostic rules and analytics. Through these online systems, operators are able to receive meaningful actionable information about the issue and its source. These analytics are widespread across machinery, auxiliary and process domains. Through this automated diagnostics platform, Data-driven insights can be generated for machine condition monitoring through advanced rule-building and data-mapping capabilities. In addition to packaged algorithms of known failure signatures, users can also create custom rules that help to capture, disseminate, and leverage knowledge of equipment, processes, and business solutions. For turbomachinery, trending of process parameters, bearing temperature and overall vibration have been used for decades to monitor condition of assets, whereas knowledgeable diagnostic personnel are required to review dynamic data like orbit shape, vibration precession, along with other attributes together to really monitor condition of machine. Now meaningful information from dynamic data can be digitized and attributes can be used in rule logics for automated diagnosis of typical malfunctions like unbalance, misalignment, rubbing, fluid induced instability, rotor bow etc. For reciprocating compressors, automated diagnosis of typical malfunctions like pressure packing leak, valve failures, crosshead pin / frame overloading, debris/liquid ingestion, auxiliary systems (lube oil, cylinder cooling system, unloader etc.) failures and several process related issues can be realized. In this paper, case studies will be demonstrated where users were able to capitalize these systems to identify some of above stated malfunctions and save their assets from expensive secondary repercussions. An operational analytics software will be demonstrated in detail with elaboration on built-in library of pre-packaged algorithms. A primary consideration is maximizing return-on-investment and minimizing payback period. Through use case studies, it will be further demonstrated on how the users were able to identify anomalies and relish 100% payback in less than 2 months of deployment.

Full textAbstract:
Abstract Fatigue damage assessment of mooring lines components is one of the main issues in the design and life extension monitoring of deepwater floating production units mooring systems. Floating units operating at several ocean regions, as in the Brazilian southeast coast and Africa west coast, are almost permanently subjected to wind-sea waves and remote waves (swell), besides wind and marine current actions. Fatigue assessment of mooring systems operating under these environmental conditions shall consider an extensive number of simultaneous environmental action load cases or rely on some simplification of the load cases. In the first case, the fatigue assessment may require a large amount of computer resources and time, making it unfeasible, for example, in the early phases of the mooring system design, where normally the analysis of several configurations is necessary. In the second case, some important aspects of the actual behavior of the environmental actions may not be considered in the fatigue analyses. This paper presents a new engineering approach for the fatigue assessment of mooring systems based on a Monte Carlo Simulation resampling using a set of simultaneous environmental conditions available in a database, sampled every 3 hours during several years. Studies show that damage estimates considering just a few resampled cases, say 5 to 10% of the cases in the database, compare very well to estimates considering the entire database. Finally, the paper also presents how to define confidence intervals of the damage estimates.

Full textAbstract:
Overview Skin cancer prevention is a component of the new Cancer Plan 2022–27, which guides the work of the Cancer Institute NSW. To lessen the impact of skin cancer on the community, the Cancer Institute NSW works closely with the NSW Skin Cancer Prevention Advisory Committee, comprising governmental and non-governmental organisation representatives, to develop and implement the NSW Skin Cancer Prevention Strategy. Primary Health Networks and primary care providers are seen as important stakeholders in this work. To guide improvements in skin cancer prevention and inform the development of the next NSW Skin Cancer Prevention Strategy, an up-to-date review of the evidence on the effectiveness and feasibility of skin cancer prevention activities in primary care is required. A research team led by the Daffodil Centre, a joint venture between the University of Sydney and Cancer Council NSW, was contracted to undertake an Evidence Check review to address the questions below. Evidence Check questions This Evidence Check aimed to address the following questions: Question 1: What skin cancer primary prevention activities can be effectively administered in primary care settings? As part of this, identify the key components of such messages, strategies, programs or initiatives that have been effectively implemented and their feasibility in the NSW/Australian context. Question 2: What are the main barriers and enablers for primary care providers in delivering skin cancer primary prevention activities within their setting? Summary of methods The research team conducted a detailed analysis of the published and grey literature, based on a comprehensive search. We developed the search strategy in consultation with a medical librarian at the University of Sydney and the Cancer Institute NSW team, and implemented it across the databases Embase, MEDLINE, PsycInfo, Scopus, Cochrane Central and CINAHL. Results were exported and uploaded to Covidence for screening and further selection. The search strategy was designed according to the SPIDER tool for Qualitative and Mixed-Methods Evidence Synthesis, which is a systematic strategy for searching qualitative and mixed-methods research studies. The SPIDER tool facilitates rigour in research by defining key elements of non-quantitative research questions. We included peer-reviewed and grey literature that included skin cancer primary prevention strategies/ interventions/ techniques/ programs within primary care settings, e.g. involving general practitioners and primary care nurses. The literature was limited to publications since 2014, and for studies or programs conducted in Australia, the UK, New Zealand, Canada, Ireland, Western Europe and Scandinavia. We also included relevant systematic reviews and evidence syntheses based on a range of international evidence where also relevant to the Australian context. To address Question 1, about the effectiveness of skin cancer prevention activities in primary care settings, we summarised findings from the Evidence Check according to different skin cancer prevention activities. To address Question 2, about the barriers and enablers of skin cancer prevention activities in primary care settings, we summarised findings according to the Consolidated Framework for Implementation Research (CFIR). The CFIR is a framework for identifying important implementation considerations for novel interventions in healthcare settings and provides a practical guide for systematically assessing potential barriers and facilitators in preparation for implementing a new activity or program. We assessed study quality using the National Health and Medical Research Council (NHMRC) levels of evidence. Key findings We identified 25 peer-reviewed journal articles that met the eligibility criteria and we included these in the Evidence Check. Eight of the studies were conducted in Australia, six in the UK, and the others elsewhere (mainly other European countries). In addition, the grey literature search identified four relevant guidelines, 12 education/training resources, two Cancer Care pathways, two position statements, three reports and five other resources that we included in the Evidence Check. Question 1 (related to effectiveness) We categorised the studies into different types of skin cancer prevention activities: behavioural counselling (n=3); risk assessment and delivering risk-tailored information (n=10); new technologies for early detection and accompanying prevention advice (n=4); and education and training programs for general practitioners (GPs) and primary care nurses regarding skin cancer prevention (n=3). There was good evidence that behavioural counselling interventions can result in a small improvement in sun protection behaviours among adults with fair skin types (defined as ivory or pale skin, light hair and eye colour, freckles, or those who sunburn easily), which would include the majority of Australians. It was found that clinicians play an important role in counselling patients about sun-protective behaviours, and recommended tailoring messages to the age and demographics of target groups (e.g. high-risk groups) to have maximal influence on behaviours. Several web-based melanoma risk prediction tools are now available in Australia, mainly designed for health professionals to identify patients’ risk of a new or subsequent primary melanoma and guide discussions with patients about primary prevention and early detection. Intervention studies have demonstrated that use of these melanoma risk prediction tools is feasible and acceptable to participants in primary care settings, and there is some evidence, including from Australian studies, that using these risk prediction tools to tailor primary prevention and early detection messages can improve sun-related behaviours. Some studies examined novel technologies, such as apps, to support early detection through skin examinations, including a very limited focus on the provision of preventive advice. These novel technologies are still largely in the research domain rather than recommended for routine use but provide a potential future opportunity to incorporate more primary prevention tailored advice. There are a number of online short courses available for primary healthcare professionals specifically focusing on skin cancer prevention. Most education and training programs for GPs and primary care nurses in the field of skin cancer focus on treatment and early detection, though some programs have specifically incorporated primary prevention education and training. A notable example is the Dermoscopy for Victorian General Practice Program, in which 93% of participating GPs reported that they had increased preventive information provided to high-risk patients and during skin examinations. Question 2 (related to barriers and enablers) Key enablers of performing skin cancer prevention activities in primary care settings included: • Easy access and availability of guidelines and point-of-care tools and resources • A fit with existing workflows and systems, so there is minimal disruption to flow of care • Easy-to-understand patient information • Using the waiting room for collection of risk assessment information on an electronic device such as an iPad/tablet where possible • Pairing with early detection activities • Sharing of successful programs across jurisdictions. Key barriers to performing skin cancer prevention activities in primary care settings included: • Unclear requirements and lack of confidence (self-efficacy) about prevention counselling • Limited availability of GP services especially in regional and remote areas • Competing demands, low priority, lack of time • Lack of incentives.

Full textAbstract:
Under the United Nations Charter, the U.N. Security Council has several important functions and powers, not least with regard to taking binding actions to maintain international peace and security. The ten elected members have the opportunity to influence this area and others during their two-year terms on the Council. In this paper, we aim to illustrate some of these opportunities, identify potential guidance from prior elected members’ experiences, and outline the key procedures that incoming elected members should be aware of as they prepare to join the Council. In doing so, we seek in part to summarize the current state of scholarship and policy analysis in an effort to make this material more accessible to States and, particularly, to States’ legal advisers. We drafted this paper with a view towards States that have been elected and are preparing to join the Council, as well as for those States that are considering bidding for a seat on the Council. As a starting point, it may be warranted to dedicate resources for personnel at home in the capital and at the Mission in New York to become deeply familiar with the language, structure, and content of the relevant provisions of the U.N. Charter. That is because it is through those provisions that Council members engage in the diverse forms of political contestation and cooperation at the center of the Council’s work. In both the Charter itself and the Council’s practices and procedures, there are structural impediments that may hinder the influence of elected members on the Security Council. These include the permanent members’ veto power over decisions on matters not characterized as procedural and the short preparation time for newly elected members. Nevertheless, elected members have found creative ways to have an impact. Many of the Council’s “procedures” — such as the “penholder” system for drafting resolutions — are informal practices that can be navigated by resourceful and well-prepared elected members. Mechanisms through which elected members can exert influence include the following: Drafting resolutions; Drafting Presidential Statements, which might serve as a prelude to future resolutions; Drafting Notes by the President, which can be used, among other things, to change Council working methods; Chairing subsidiary bodies, such as sanctions committees; Chairing the Presidency; Introducing new substantive topics onto the Council’s agenda; and Undertaking “Arria-formula” meetings, which allow for broader participation from outside the Council. Case studies help illustrate the types and degrees of impact that elected members can have through their own initiative. Examples include the following undertakings: Canada’s emphasis in 1999–2000 on civilian protection, which led to numerous resolutions and the establishment of civilian protection as a topic on which the Council remains “seized” and continues to have regular debates; Belgium’s effort in 2007 to clarify the Council’s strategy around addressing natural resources and armed conflict, which resulted in a Presidential Statement; Australia’s efforts in 2014 resulting in the placing of the North Korean human rights situation on the Council’s agenda for the first time; and Brazil’s “Responsibility while Protecting” 2011 concept note, which helped shape debate around the Responsibility to Protect concept. Elected members have also influenced Council processes by working together in diverse coalitions. Examples include the following instances: Egypt, Japan, New Zealand, Spain, and Uruguay drafted a resolution that was adopted in 2016 on the protection of health-care workers in armed conflict; Cote d’Ivoire, Kuwait, the Netherlands, and Sweden drafted a resolution that was adopted in 2018 condemning the use of famine as an instrument of warfare; Malaysia, New Zealand, Senegal, and Venezuela tabled a 2016 resolution, which was ultimately adopted, condemning Israeli settlements in Palestinian territory; and A group of successive elected members helped reform the process around the imposition of sanctions against al-Qaeda and associated entities (later including the Islamic State of Iraq and the Levant), including by establishing an Ombudsperson. Past elected members’ experiences may offer some specific pieces of guidance for new members preparing to take their seats on the Council. For example, prospective, new, and current members might seek to take the following measures: Increase the size of and support for the staff of the Mission to the U.N., both in New York and in home capitals; Deploy high-level officials to help gain support for initiatives; Partner with members of the P5 who are the informal “penholder” on certain topics, as this may offer more opportunities to draft resolutions; Build support for initiatives from U.N. Member States that do not currently sit on the Council; and Leave enough time to see initiatives through to completion and continue to follow up after leaving the Council.

Full textAbstract:
There is increasingly strong evidence that taxation can contribute to expanded government responsiveness and accountability. However, such positive connections are not guaranteed. Rather, they are shaped by the political and economic context and specific policies adopted by governments and civil society actors. Without an environment that enables tax bargaining, there is a risk that taxation will amount to little more than forceful extraction. We consider how such enabling environments may be fostered through two mixed methods case studies of tax transparency and taxpayer engagement in Sierra Leone and Ghana. We highlight two key sets of findings. First, tax transparency is only meaningful if it is accessible and easily understood by taxpayers and relates to their everyday experiences and priorities. In particular, we find that taxpayers do not just want basic information about tax obligations or aggregate revenue collected, but information about how much revenue should have been collected and how revenues were spent. At the same time, taxpayers do not want information to be shared with them through a one-way form of communication, but rather want to have spaces for dialogue and interaction with tax and government officials, including through public meetings and radio call-in programmes. Second, strategies to encourage taxpayer engagement are more likely to be effective where forums for engagement are perceived by taxpayers to be safe, secure, and sincere means through which to engage with government officials. This has been most successful where governments have visibly demonstrated responsiveness to citizen concerns, even on a small scale, while partnering with civil society to foster trust, dialogue and expanded knowledge. These findings have significant implications for how governments design taxpayer education and engagement programmes and how civil society actors and development partners can support more equitable and accountable tax systems. Our findings provide concrete lessons for how governments can ensure that information shared with taxpayers is meaningful and accessible. Moreover, we show that civil society actors can play important roles as translators of tax information, enablers of public forums and dialogues around tax issues, and trainers of taxpayers, supporting greater tax literacy and sustained citizen engagement.
