This paper proposes a novel interval intersection-based protocol for time coordination in wireless sensor and IoT networks. The common notion of time amid the nodes in a distributed environment can be achieved through the message exchange process, which experiences random delay (send, access, propagation, and reception), thus making the time coordination process difficult. Several researchers have proposed algorithms to handle the error in estimation using various methods. This paper analytically analyzes the proposed novel unidirectional interval intersection method for mitigating the uncertainty in the interval width. The offset and slope estimation errors are then reduced under different conditions to verify the effectiveness of the proposed coordination algorithm. The model is simulated under three different delay models: uniform, normal, and truncated exponential. Their performance is then compared in terms of coordination efficiency.

Estimating a time interval and temporally coordinating movements in space are fundamental skills, but the relationships between these different forms of timing, and the neural processes that they incur, are not well understood. While different theories have been proposed to account for time perception, time estimation, and the temporal patterns of coordination, there are no general mechanisms which unify these various timing skills. This study considers whether a model of perceptuo-motor timing, the τGUIDE, can also describe how certain judgements of elapsed time are made. To evaluate this, an equation for determining interval estimates was derived from the τGUIDE model and tested in a task where participants had to throw a ball and estimate when it would hit the floor. The results showed that in accordance with the model, very accurate judgements could be made without vision (mean timing error 19.24 msec), and the model was a good predictor of skilled participants' estimate timing. It was concluded that since the τGUIDE principle provides temporal information in a generic form, it could be a unitary process that links different forms of timing.

This paper proposes an efficient origin-estimation bandwidth (OD band) model, which provides dedicated progression bands for arterial traffic based on the real-time dynamic matrix of their estimated OD pairs. The innovations of the OD band model are as follows: First, the dynamics of through and turning-in/out traffics are analyzed based on the matrix of their estimated OD pairs, and used to generate the traffic movement sequence at continuous intersections; Second, the end-time of green interval for lag-lag phase sequence at continuous intersections is determined according to the relevant constraints, the relationship between the start/end-time of green interval and the minimum/maximum green intervals; Third, the bandwidths of the two directions of the artery ware produced, after being weighted by their traffic demands. The intuitiveness, convenience, and feasibility of the OD band model were fully demonstrated through a case study. Overall, the OD band model helps to produce bi-directional progression bands for traffic with many turning movements on the artery, and enables the through and turning-in/out traffics to proceed through continuous intersections, when the signals at those intersections are green.

We tested the hypothesis that the cardiac-related rhythm in sympathetic nerve discharge (SND) results from the forcing of a central oscillator to the frequency of the heart beat by pulse-synchronous baroreceptor afferent nerve activity. For this purpose, time series analysis was used to examine the phase relations between the brachial arterial pulse (AP) and cardiac-related activity recorded from the postganglionic inferior cardiac sympathetic nerve (CN) in urethan-anesthetized cats. Specifically, we made cycle-by-cycle measurements of peak systolic blood pressure, heart period, CN burst amplitude, and the phase angle (and corresponding interval) between peak systole and the next peak of CN activity. As the steady-state level of systolic blood pressure was raised by increasing the rate of a constant intravenous infusion of phenylephrine, we observed transitions from no phase-locking of CN activity to the AP to either phase-locking of variable strength or phase walk through part of the cardiac-cycle on the time scale of respiration. Phase walk is defined as a progressive and systematic change in the phase lag of cardiac-related CN activity relative to peak systole. Raising blood pressure strengthened phase-locking and either increased or decreased the mean interval between peak systole and the next peak of CN activity even when the change in heart period was small. CN burst amplitude and the interval between peak systole and the next peak of CN activity were inversely related, but the strength of the relationship varied considerably with experimental conditions. The relationship was strongest during phase walk. Step-wise increases in blood pressure induced by abdominal aortic obstruction led to an abrupt increase in the phase lag of CN activity relative to peak systole even when heart rate was not changed. We refer to such changes as sharp phase transitions that are a general property of dynamical nonlinear systems. The results support the view that the cardiac-related rhythm in SND is a forced nonlinear oscillation rather than the consequence of periodic inhibition of randomly generated activity.

Full textAbstract:
Due to the limitation of economics and time cost, the data obtained from hydro-turbine coordination field test are insufficient to fully guide the setting of unit operating parameters. To enlarge the amount of data, realise power point tracking, and avoid the problems of high non-linearity with hydro-turbine physical model which is difficult to simulate in actual field, a mathematical prediction model is proposed based on an improved multi-layer neural network. Using the rule activation function, L2 regularisation, Adam optimiser and its gradient parameters are optimised by PSO algorithm in the prediction model. It is found that lacking true value in the process of anti-normalisation leads to difficulty for actual forecast of neural network. Therefore, an adaptive anti-normalisation strategy is proposed to improve the actual prediction accuracy, which can judge the value of the interval. According to the analysis of examples with hydro-turbine coordination and non-coordination test, the results show that the proposed prediction model and interval strategy can effectively forecast the coordination operating conditions of the turbine with high accuracy under small samples.

In response to the problem of mismatch between new energy output and multi-energy load requirement in multi-energy power systems, this article proposes a dynamic optimization model for new energy output in multiple time intervals based on multi-energy storage coordination. First, considering the energy conversion characteristics of multi-energy storage, the dynamic optimization method of new energy output based on the discrete division of subinterval of scheduling time is studied. Then, considering the cost of adjusting various resources comprehensively, the optimization objective of new energy output is studied, and a model-solving method based on a directed graph topology distributed algorithm is proposed. Finally, simulation verification was conducted, and the simulation results showed that the method proposed in this paper can effectively suppress the new energy fluctuation and reduce peak-shaving costs.

Distribution systems are mostly composed of radial structures, which are susceptible to an increased variability and complexity of system operation due to frequent line changes during operation. When multiple changes in distribution lines occur simultaneously, the relative positions of protective devices also change. The existing protection coordination method of distribution lines is configured by considering the operation characteristics and coordination time interval (CTI) of all protective devices in series from the substation to the terminal load. Therefore, the protection coordination algorithm needs to be redesigned whenever a line is changed or a protective device is added to the distribution line for which the existing protection coordination algorithm has been set. In addition, existing protection coordination methods require complex calculations and procedures, which are subject to human errors and are less feasible for responding in real-time to changes in the distribution system. In this paper, we propose the adaptive time–current curve (TCC) method by selecting the time dial setting (TDS) and minimum response time (MRT) of individual protective devices in accordance with the relative distance based on the linear optimization technique. Using PSCAD/EMTDC, a power system analysis program, the minimum operating current and the fault current of each protective device are obtained, and the proposed protection coordination algorithm is verified according to the series configuration relationship of the protective devices. Finally, the proposed method is applied to an actual distribution line to verify the improvement over the existing protection coordination.

Background: There is limited data on the optimal time interval between the last dose of neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) in high-grade serous ovarian carcinoma (HGSC). Methods: We retrospectively identified patients with stage IIIC/IV HGSC who received NACT followed by IDS during a 15-year period (January 2003–December 2018) in our Institution. Results: Overall, 115 patients with stage IIIC/IV HGSC were included. The median age of diagnosis was 62.7 years (IQR: 14.0). A total of 76.5% (88/115) of patients were diagnosed with IIIC HGSC and 23.5% (27/115) with IV HGSC. Median PFS was 15.7 months (95% CI: 13.0–18.5), and median OS was 44.7 months (95% CI: 38.8–50.5). Patients were categorized in groups according to the time interval from NACT to IDS: <4 weeks (group A); 4–5 weeks (group B); 5–6 weeks (group C); >6 weeks (group D). Patients with a time interval IDS to NACT ≥4 weeks had significantly shorter PFS (p = 0.004) and OS (p = 0.002). Median PFS was 26.6 months (95% CI: 24–29.2) for patients undergoing IDS <4 weeks after NACT vs. 14.4 months (95% CI: 12.6–16.2) for those undergoing IDS later (p = 0.004). Accordingly, median OS was 66.3 months (95% CI: 39.1–93.4) vs. 39.4 months (95% CI: 31.8–47.0) in the <4 week vs. >4 week time interval NACT to IDS groups (p = 0.002). On multivariate analysis, the short time interval (<4 weeks) from NACT to IDS was an independent factor of PFS (p = 0.004) and OS (p = 0.003). Conclusion: We have demonstrated that performing IDS within four weeks after NACT may be associated with better survival outcomes. Multidisciplinary coordination among ovarian cancer patients is required to avoid any unnecessary delays.

Background/Objective Eye–hand coordination, which is essential for activities of daily living, develops with age. The objective of this study was to investigate the temporal patterns of visual fixation coupled with hands during manual action on objects in children and young adults. Methods Twelve eight-year-old children and 12 young adults performed the Jebsen–Taylor Hand Function Test (JTT) wearing eye-tracking glasses. The interval from the eye arrival time to the hand arrival time on an object was measured as eye–hand arrival span. The interval between the eye departure time and the hand departure time from the object was measured as eye–hand departure span. Eye–hand arrival span, eye–hand departure span and the performance time to complete the JTT were compared between children and young adults. Correlation between eye–hand arrival span and eye–hand departure span was analysed to identify the mechanism of eye–hand coordination. Results Compared with young adults, children showed longer performance time but shorter eye–hand arrival span and eye–hand departure span in the JTT. The difference in mean eye–hand arrival span of overall JTT between children and young adults was significant for both hands, whereas differences in the mean eye–hand departure span on the overall JTT and the total performance time were significant for the non-dominant hand. The eye–hand arrival span was positively correlated with the eye–hand departure span. Conclusion This study demonstrated temporal differences in eye–hand coordination between children and young adults. Temporal patterns of visual fixation coupled to object manipulation could be useful information about the sensorimotor system in the field of occupational therapy.

Full textAbstract:
Conventional power system alone cannot meet the ever growing needs of electrical power
in the world in a reliable manner. Under these circumstances, large penetration of Dis-
tributed generators in the distribution level of the power system network is a great boon
to the consumers. Due to the penetration of distributed generators (DGs) of large ca-
pacities, the difference of current seen by protective relays, during faults in their primary
and backup regions is considerable. As a result, the settings of the relay curve suitable
for its primary region, is not capable of tripping within the desired time during fault
in its backup region. This could lead to several issues with the protection system such
as relay miscoordination, delay in relay operation and also failure in the relay operation
(blinding). This thesis discusses a methodology to solve such issues by identifying the
current status of micro-grid confi guration. The proposed communication based method
works well by maintaining the CTI between the relays, irrespective of the source strength
(weak or strong), or during different mode of operation of the micro-grid (islanded or
grid connected) as well as for different micro-grid con figuration (radial or looped). Even
when fault current is less than the load current, the suggested scheme is able to trip
within the desired time and provides proper relay coordination. The performance of the
communication based relay coordination is validated by comparing the updated relay
tripping time with conventional operating time of the relay. The proposed scheme has
been emulated in hardware and the results have been validated with the simulation re-
sults. The thesis also discusses a methodology to reduce the total tripping time of the
relays and this is achieved by a linear programming algorithm running in the Central
Master controller(MC) to coordinate the relays using IEEE Standard curves.
The thesis also explains a relaying scheme, which uses a classi fication approach using
multi-class SVM for improving the accuracy in relay coordination. Without using any

This chapter considers the research project as a temporary, liminal community, always at risk of dispersal from external incentives and internal frustrations. Participant commitment can be sustained through the traditional mechanism of ritual, while intellectual insight advances in play; junior researchers can animate both modes of sociability and achieve influence thereby. Shared space and shared time coordinate planned interactions and also facilitate spontaneous emergences. Examples from the Göttingen Interdisciplinary Working Group on Cultural Property illustrate the intellectual payoffs of coffee machines, dancing, visual project mapping, and writing the grant renewal application as exercises in social as well as intellectual coordination. In the middle stages of research, a tolerance for conceptual ambiguity at the project level can facilitate lower-level successes and interactions.

AbstractThe human circadian system drives 24-h rhythms in all aspects of biochemistry, physiology and behaviour. This rhythmicity ensures that the right function occurs at the right time, and separates incompatible functions. Rhythmic synchronisation is key to overall health and wellbeing, and light input from the day-night cycle is the primary ‘zeitgeber’ or entraining agent. Coordination of internal clocks promotes positive mood, optimum alertness and performance, and ensures sleep quality essential for learning and memory. Indoor light intensity is rarely sufficient to stabilise daily entrainment, while even an hour outdoors in the morning can significantly enhance cognitive function, academic achievement, and physical condition.

This chapter proposes a new hybrid MAC protocol for direct communication among M2M devices with gateway coordination. The proposed protocol combines the benefits of both contention-based and reservation-based MAC schemes. The authors assume that the contention and reservation portion of M2M devices is a frame structure, which is comprised of two sections: contention interval (CI) and transmission interval (TI). The CI duration follows p-persistent CSMA mechanism, which allows M2M devices to contend for the transmission slots with equal priorities. After contention, only those devices which have won time-slots are allowed to transmit data packets during TI. In the proposed MAC scheme, the TI duration follows TDMA mechanism. Each M2M transmitter device and its corresponding one-hop distant receiver communicate using IEEE 802.11 DCF protocol within each TDMA slot to overcome various limitations of TDMA mechanism. The authors evaluate the performance of the proposed hybrid MAC protocol in terms of aggregate throughput, average transmission delay, channel utility, and energy consumption.

Free riding is endemic. But it is not the type of first-order free riding that politicians and EU officials publicly chastised. Instead, fiscal policy coordination is burdened by a serious internal enforcement problem; that is, second-order free riding. The argument presented here is different from the usual decrying of a lack of enforcement in fiscal policy coordination, which is said to invite member states to engage in rampant fiscal free riding. This chapter contests that without internal enforcement within the EU, fiscal policy coordination has come to rely on market discipline with dire consequences for its members. The chapter demonstrates that, in contrast to fiscal rules and intergovernmental agreements, the incentives provided by market discipline shape public finances.

Abstract This descriptive chapter highlights the organization and functioning of the Rapid Action Force, or RAF. After briefly underscoring the hierarchy within which the Force operates, and its position as a subsidiary of the CRPF, the chapter uses data from the Armed Conflict Location & Event Data Project (ACLED) and the Times of India archive to understand personnel deployments. Then, it presents a brief case study as well as information gleaned through qualitative interviews about the Force’s role during the 2016 Haryana reservation agitation. It points to certain challenges that may moderate the Rapid Action Force’s agility, including resource deficits, a lack of coordination between the Center and states about deployment, the Force’s inability to retain organizational command during riot-like situations, and political considerations that make policymakers hesitant about seeking assistance about addressing law and order from the federal government.

In line with the European Union’s (EU’s or Union’s) dual commitment to human rights and effective multilateralism, cooperation with the United Nations (UN) is an important element of the Union’s external human rights policy. Owing to a strong internal coordination mechanism, the EU acts as one of the most cohesive regional blocs at the UN. It successfully promotes a range of resolutions and ranks among the principal donors of UN human rights institutions. Nevertheless, the EU’s engagement with the UN is not without challenges, both external and internal in nature. Limited participation rights and time-consuming internal coordination processes, but also the increasing tendency among EU Member States to act outside of the Union, limit the EU’s potential for assuming its intended leadership role. This chapter provides a brief introduction to the UN human rights system and explores the Union’s political commitment to engaging with the UN, as well as the legal framework for doing so. After a brief overview of the Union’s internal coordination and external representation mechanisms, the chapter analyses the different tools that the EU has at its disposal in the UN. Finally, the chapter explores the opportunities and the challenges of EU-UN cooperation and concludes with a set of recommendations.

Abstract The overarching goal of the geriatric assessment is to develop a holistic understanding of the older patient as a means to identify emerging problems and individual capabilities. This information guides treatment, care coordination, and evaluation of long-term care needs. Assessment of the older adult requires a multifaceted approach that encompasses physical, cognitive, and psychosocial domains. The comprehensive geriatric assessment takes this approach a step further. It is targeted toward the frail older adult and involves an interdisciplinary team of geriatric care providers. Both the general assessment and the comprehensive assessment aim to enhance quality of life and optimize function. Given the time constraints placed on practicing physicians, a strategy of rapid screening of key geriatric domains, followed by a more in-depth assessment of worrisome areas, is an effective approach.

This chapter examines one line of criticism of the Rational Expectations Hypothesis (REH): expectational coordination failures. It begins by addressing the question of what went wrong with standard economic theory in general and with its modeling principles in particular and offers three answers relating to the diversification of modeling, the rationality hypothesis, and expectational coordination. It then considers the rise of REH in modern economic theory before discussing three avenues of criticism against REH: internal challenges, external criticisms, and criticism based on real-time learning. It also explains how a critical assessment of REH in different contexts changes the standard (REH-based) economic intuition, focusing on the question of the value of new financial instruments; the informational efficiency of the market; and the “good” expectational coordination that Real Business Cycles (RBC)-like models.

A distributed system is one that consists of separate elements located at different points in space, the functions and resources of the system are divided between the elements, and the location in space affects the functioning of the system as a whole. A special case of distributed systems is distributed control systems (DCS). In today's market, there are a large number of distributed control systems created at different times and by different companies. In the work, a method of decentralized coordination of control of distributed cyber-physical systems with continuous objects is developed, a RKFS model with a continuous production object and resource state management is developed, which is characterized by taking into account the mutual influence of controlled elements of a continuous production object and resource costs for production and is presented in in the form of a two-flow graph, an indicator of the level of coordination is proposed, which determines the state of coordination in the interval from chaos to a given deterministic state, which allows to evaluate the effectiveness of the coordination system, the criterion of coordination of the RKFS with continuous production facilities, which is based on the model of a continuous production facility, and distribution of states of object elements in space and time, the method of forecasting the state of distributed cyber-physical systems with continuous objects, which is based on the RKFS model with a continuous production object and resource management of state and space-time spectrum, has been improved states and disturbances.

Brain is getting wide attention these days. Until very recently. it is deeply associated with Digital Computing. But Recently the importance of Analog is getting wide attention and such word as Brain-morphic Computing (BMC) is emerging. Although whether it is Digital or Analog, the attention is focused only on Brain. But as William Wordsworth indicated "Our heart leaps up when we behold a rainbow in the sky", our heart plays a very important role in our Emotion. The world has been the Industrial World and Euclidean Approach (EA) played a leading role. EA is interval scale-based with units and requires orthonormality among their datasets. But as the curse of dimensionality teaches us, we cannot solve the problem, if its number of dimensions becomes too large. The environments and situations of our daily life, however, change from moment to moment. But we spend our daily life safely and happily. Change is related with movement. And human movement is divided into two: Motion, which can be observed from outside and Motor, which is the movement inside of us, such as those of muscles, etc. Our discussion on human movements has been focused on Motion. Our muscles harden when we get close to the target object and they move together with our skeleton, forming the musculoskeletal system. Thus, we can control our motion trajectories. But at the first stage, our motion trajectories vary widely from time to time. This is because the environment and the situation vary from time to time and we make our efforts to adapt to these external changes. We coordinate all body parts to balance our body to adapt to the changing environment and the situation. In other words, our internal Motor or such parts as Muscles. etc. come to play an important role. Coordination becomes more and more important. In short, sensorimotor or proprioception has come to play an important role.

Full textAbstract:
This report critically examines, for the first time, the capacity of Canada’s water sector with respect to meeting and helping other countries meet the water-related targets of the UN’s global sustainable development agenda. Several components of this capacity are examined, including water education and research, investment in water projects that Canada makes internally and externally, and experiences in water technology and governance. Analysis of the water education system suggests that there is a broad capability in institutions of higher learning in Canada to offer training in the diverse subject areas important in water. In most cases, however, this has not led to the establishment of specific water study programmes. Only a few universities provide integrated water education. There is a need for a comprehensive listing of water-related educational activities in universities and colleges — a useful resource for potential students and employers. A review of recent Canadian water research directions and highlights reveals strong and diverse water research capacity and placed the country among global leaders in this field. Canada appears to be within the top 10 countries in terms of water research productivity (publications) and research impact (citations). Research capacity has been traditionally strong in the restoration and protection of the lakes, prediction of changes in climate, water and cryosphere (areas where water is in solid forms such as ice and snow), prediction and management of floods and droughts. There is also a range of other strong water research directions. Canada is not among the top 10 global water aid donors in absolute dollar numbers; the forerunners are, as a rule, the countries with higher GDP per capita. Canadian investments in Africa water development were consistently higher over the years than investments in other regions of the global South. The contributions dropped significantly in recent years overall, also with a decline in aid flow to Africa. Given government support for the right business model and access to resources, there is significant capacity within the Canadian water sector to deliver water technology projects with effective sustainable outcomes for the developing world. The report recommends several potential avenues to elevate Canada’s role on the global water stage, i.e. innovative, diverse and specific approaches such as developing a national inventory of available water professional capacity, and ranking Universities on the strength of their water programmes coordinating national contributions to global sustainability processes around the largest ever university-led water research programme in the world – the 7-year Global Water Futures program targeting specific developmental or regional challenges through overseas development aid to achieve quick wins that may require only modest investments resolving such chronic internal water challenges as water supply and sanitation of First Nations, and illustrating how this can be achieved within a limited period with good will strengthening and expanding links with UN-Water and other UN organisations involved in global water policy work To improve water management at home, and to promote water Canadian competence abroad, the diverse efforts of the country’s water sector need better coordination. There is a significant role for government at all levels, but especially federally, in this process.

Full textAbstract:
Emergency Relief (ER) is a Department of Social Services (DSS) funded program, delivered by 197 community organisations (ER Providers) across Australia, to assist people facing a financial crisis with financial/material aid and referrals to other support programs. ER has been playing this important role in Australian communities since 1979. Without ER, more people living in Australia who experience a financial crisis might face further harm such as crippling debt or homelessness. The Emergency Relief National Coordination Group (NCG) was established in April 2020 at the start of the COVID-19 pandemic to advise the Minister for Families and Social Services on the implementation of ER. To inform its advice to the Minister, the NCG partnered with the Institute for Governance at the University of Canberra to conduct research to understand the issues and challenges faced by ER Providers and Service Users in local contexts across Australia. The research involved a desktop review of the existing literature on ER service provision, a large survey which all Commonwealth ER Providers were invited to participate in (and 122 responses were received), interviews with a purposive sample of 18 ER Providers, and the development of a program logic and theory of change for the Commonwealth ER program to assess progress. The surveys and interviews focussed on ER Provider perceptions of the strengths, weaknesses, future challenges, and areas of improvement for current ER provision. The trend of increasing case complexity, the effectiveness of ER service delivery models in achieving outcomes for Service Users, and the significance of volunteering in the sector were investigated. Separately, an evaluation of the performance of the NCG was conducted and a summary of the evaluation is provided as an appendix to this report. Several themes emerged from the review of the existing literature such as service delivery shortcomings in dealing with case complexity, the effectiveness of case management, and repeat requests for service. Interviews with ER workers and Service Users found that an uplift in workforce capability was required to deal with increasing case complexity, leading to recommendations for more training and service standards. Several service evaluations found that ER delivered with case management led to high Service User satisfaction, played an integral role in transforming the lives of people with complex needs, and lowered repeat requests for service. A large longitudinal quantitative study revealed that more time spent with participants substantially decreased the number of repeat requests for service; and, given that repeat requests for service can be an indicator of entrenched poverty, not accessing further services is likely to suggest improvement. The interviews identified the main strengths of ER to be the rapid response and flexible use of funds to stabilise crisis situations and connect people to other supports through strong local networks. Service Users trusted the system because of these strengths, and ER was often an access point to holistic support. There were three main weaknesses identified. First, funding contracts were too short and did not cover the full costs of the program—in particular, case management for complex cases. Second, many Service Users were dependent on ER which was inconsistent with the definition and intent of the program. Third, there was inconsistency in the level of service received by Service Users in different geographic locations. These weaknesses can be improved upon with a joined-up approach featuring co-design and collaborative governance, leading to the successful commissioning of social services. The survey confirmed that volunteers were significant for ER, making up 92% of all workers and 51% of all hours worked in respondent ER programs. Of the 122 respondents, volunteers amounted to 554 full-time equivalents, a contribution valued at $39.4 million. In total there were 8,316 volunteers working in the 122 respondent ER programs. The sector can support and upskill these volunteers (and employees in addition) by developing scalable training solutions such as online training modules, updating ER service standards, and engaging in collaborative learning arrangements where large and small ER Providers share resources. More engagement with peak bodies such as Volunteering Australia might also assist the sector to improve the focus on volunteer engagement. Integrated services achieve better outcomes for complex ER cases—97% of survey respondents either agreed or strongly agreed this was the case. The research identified the dimensions of service integration most relevant to ER Providers to be case management, referrals, the breadth of services offered internally, co-location with interrelated service providers, an established network of support, workforce capability, and Service User engagement. Providers can individually focus on increasing the level of service integration for their ER program to improve their ability to deal with complex cases, which are clearly on the rise. At the system level, a more joined-up approach can also improve service integration across Australia. The key dimensions of this finding are discussed next in more detail. Case management is key for achieving Service User outcomes for complex cases—89% of survey respondents either agreed or strongly agreed this was the case. Interviewees most frequently said they would provide more case management if they could change their service model. Case management allows for more time spent with the Service User, follow up with referral partners, and a higher level of expertise in service delivery to support complex cases. Of course, it is a costly model and not currently funded for all Service Users through ER. Where case management is not available as part of ER, it might be available through a related service that is part of a network of support. Where possible, ER Providers should facilitate access to case management for Service Users who would benefit. At a system level, ER models with a greater component of case management could be implemented as test cases. Referral systems are also key for achieving Service User outcomes, which is reflected in the ER Program Logic presented on page 31. The survey and interview data show that referrals within an integrated service (internal) or in a service hub (co-located) are most effective. Where this is not possible, warm referrals within a trusted network of support are more effective than cold referrals leading to higher take-up and beneficial Service User outcomes. However, cold referrals are most common, pointing to a weakness in ER referral systems. This is because ER Providers do not operate or co-locate with interrelated services in many cases, nor do they have the case management capacity to provide warm referrals in many other cases. For mental illness support, which interviewees identified as one of the most difficult issues to deal with, ER Providers offer an integrated service only 23% of the time, warm referrals 34% of the time, and cold referrals 43% of the time. A focus on referral systems at the individual ER Provider level, and system level through a joined-up approach, might lead to better outcomes for Service Users. The program logic and theory of change for ER have been documented with input from the research findings and included in Section 4.3 on page 31. These show that ER helps people facing a financial crisis to meet their immediate needs, avoid further harm, and access a path to recovery. The research demonstrates that ER is fundamental to supporting vulnerable people in Australia and should therefore continue to be funded by government.

Full textAbstract:
Background An estimated 292 million people are living with chronic hepatitis B virus (HBV) infection globally, including 223,000 people in Australia. HBV diagnosis and linkage of people living with HBV to clinical care is suboptimal in Australia, with 27% of people living with HBV undiagnosed and 77% not receiving regular HBV clinical care. This systematic review aimed to characterize population-level interventions implemented to enhance all components of HBV care cascade and analyse the effectiveness of interventions. Review questions Question 1: What population-level interventions, programs or policy approaches have been shown to be effective in reducing the incidence of hepatitis B; and that may not yet be fully rolled out or evaluated in Australia demonstrate early effectiveness, or promise, in reducing the incidence of hepatitis B? Question 2: What population-level interventions and/or programs are effective at reducing disease burden for people in the community with hepatitis B? Methods Four bibliographic databases and 21 grey literature sources were searched. Studies were eligible for inclusion if the study population included people with or at risk of chronic HBV, and the study conducted a population-level interventions to decrease HBV incidence or disease burden or to enhance any components of HBV care cascade (i.e., diagnosis, linkage to care, treatment initiation, adherence to clinical care), or HBV vaccination coverage. Studies published in the past 10 years (since January 2012), with or without comparison groups were eligible for inclusion. Studies conducting an HBV screening intervention were eligible if they reported proportion of people participating in screening, proportion of newly diagnosed HBV (participant was unaware of their HBV status), proportion of people received HBV vaccination following screening, or proportion of participants diagnosed with chronic HBV infection who were linked to HBV clinical care. Studies were excluded if study population was less than 20 participants, intervention included a pharmaceutical intervention or a hospital-based intervention, or study was implemented in limited clinical services. The records were initially screened by title and abstract. The full texts of potentially eligible records were reviewed, and eligible studies were selected for inclusion. For each study included in analysis, the study outcome and corresponding 95% confidence intervals (95%CIs) were calculated. For studies including a comparison group, odds ratio (OR) and corresponding 95%CIs were calculated. Random effect meta-analysis models were used to calculate the pooled study outcome estimates. Stratified analyses were conducted by study setting, study population, and intervention-specific characteristics. Key findings A total of 61 studies were included in the analysis. A large majority of studies (study n=48, 79%) included single-arm studies with no concurrent control, with seven (12%) randomised controlled trials, and six (10%) non-randomised controlled studies. A total of 109 interventions were evaluated in 61 included studies. On-site or outreach HBV screening and linkage to HBV clinical care coordination were the most frequent interventions, conducted in 27 and 26 studies, respectively. Question 1 We found no studies reporting HBV incidence as the study outcome. One study conducted in remote area demonstrated that an intervention including education of pregnant women and training village health volunteers enhanced coverage of HBV birth dose vaccination (93% post-intervention, vs. 81% pre-intervention), but no data of HBV incidence among infants were reported. Question 2 Study outcomes most relevant to the HBV burden for people in the community with HBV included, HBV diagnosis, linkage to HBV care, and HBV vaccination coverage. Among randomised controlled trials aimed at enhancing HBV screening, a meta-analysis was conducted including three studies which implemented an intervention including community face-to-face education focused on HBV and/or liver cancer among migrants from high HBV prevalence areas. This analysis demonstrated a significantly higher HBV testing uptake in intervention groups with the likelihood of HBV testing 3.6 times higher among those participating in education programs compared to the control groups (OR: 3.62, 95% CI 2.72, 4.88). In another analysis, including 25 studies evaluating an intervention to enhance HBV screening, a pooled estimate of 66% of participants received HBV testing following the study intervention (95%CI: 58-75%), with high heterogeneity across studies (range: 17-98%; I-square: 99.9%). A stratified analysis by HBV screening strategy demonstrated that in the studies providing participants with on-site HBV testing, the proportion receiving HBV testing (80%, 95%CI: 72-87%) was significantly higher compared to the studies referring participants to an external site for HBV testing (54%, 95%CI: 37-71%). In the studies implementing an intervention to enhance linkage of people diagnosed with HBV infection to clinical care, the interventions included different components and varied across studies. The most common component was post-test counselling followed by assistance with scheduling clinical appointments, conducted in 52% and 38% of the studies, respectively. In meta-analysis, a pooled estimate of 73% of people with HBV infection were linked to HBV clinical care (95%CI: 64-81%), with high heterogeneity across studies (range: 28-100%; I-square: 99.2%). A stratified analysis by study population demonstrated that in the studies among general population in high prevalence countries, 94% of people (95%CI: 88-100%) who received the study intervention were linked to care, significantly higher than 72% (95%CI: 61-83%) in studies among migrants from high prevalence area living in a country with low prevalence. In 19 studies, HBV vaccination uptake was assessed after an intervention, among which one study assessed birth dose vaccination among infants, one study assessed vaccination in elementary school children and 17 studies assessed vaccination in adults. Among studies assessing adult vaccination, a pooled estimate of 38% (95%CI: 21-56%) of people initiated vaccination, with high heterogeneity across studies (range: 0.5-93%; I square: 99.9%). A stratified analysis by HBV vaccination strategy demonstrated that in the studies providing on-site vaccination, the uptake was 78% (95%CI: 62-94%), significantly higher compared to 27% (95%CI: 13-42%) in studies referring participants to an external site for vaccination. Conclusion This systematic review identified a wide variety of interventions, mostly multi-component interventions, to enhance HBV screening, linkage to HBV clinical care, and HBV vaccination coverage. High heterogeneity was observed in effectiveness of interventions in all three domains of screening, linkage to care, and vaccination. Strategies identified to boost the effectiveness of interventions included providing on-site HBV testing and vaccination (versus referral for testing and vaccination) and including community education focussed on HBV or liver cancer in an HBV screening program. Further studies are needed to evaluate the effectiveness of more novel interventions (e.g., point of care testing) and interventions specifically including Indigenous populations, people who inject drugs, men who have sex with men, and people incarcerated.
