STRUCTURAL FEATURES OF DRILLING EQUIPMENT COMPONENTS USING MATERIALS WITH THERMOELASTIC PHASE TRANSFORMATIONS

Alloys exhibiting thermoelastic phase transformations are increasingly being used in various industries. This is due to their shape memory effect and the phenomenon of pseudoelasticity (superelasticity), which can significantly improve the performance of various technical systems. Equipment for drilling oil and gas wells is one of the most demanding in terms of reliability and service life, in connection with which the gradual introduction of the above-described intelligent materials and the phenomena they manifest in the oil and gas industry began. This article analyzes the developed design and proposes methods of mounting/dismounting roller bit elements made according to the proposed design using an alloy with thermoelastic phase transformations, namely the shape memory effect, and compares them with existing designs. Computational studies and computational analysis of the design of the fastening of drilling equipment elements using the Solid Works program and the Solid Works Simulation module were carried out, which showed significant advantages of the proposed method when applying the shape memory effect as a method of geometric fixation during installation compared to interference fit. Tests were also carried out on the IR-200-0 breaking machine in order to verify and confirm the theoretical results obtained using special equipment, with the use of which the reliability of fixation due to the intermediate bushing with taper was determined. As an example, sleeves with an inclination angle to the axis of the cone of 3 degrees were made, fixed in the hole with a reverse taper with a response angle of inclination. The tests confirmed the assumptions made and the results obtained in the course of theoretical calculations and computer modeling, showing that even in the martensitic state this alloy fixes the teeth in special holes of the rolling cutter more reliably compared to the interference fit, which, in turn, makes it possible to conclude that it is advisable to use the proposed installation method, which gives obvious advantages over existing ones.

Cellfare: Delivering Self-Targeted Social Protection Using Mobile Phones

This article proposes a new form of self-targeted social protection scheme: beneficiaries carry out a series of small tasks on their mobile phones, each linked to a small payment. Key advantages over traditional public works include potentially large reductions in leakage, costs, and delays. The proposed scheme may also be suitable to wider demographics as it does not require physical labour and can be availed from home. A prototype implementation of a ‘cellfare’ scheme was tested in rural India, and 42 participants with experience of the Mahatma Gandhi National Rural Employment Guarantee Act, a large Indian public works programme, favourably compared the proposed scheme to the existing one.

Abstract B099: Addressing cancer disparities in the United States-Affiliated Pacific Island jurisdictions: Insights from the Scaling What Works program

Abstract Purpose The Scaling What Works (SWW) program aimed to build the capacity of National Comprehensive Cancer Control Program (NCCCP) recipients to scale three CDC-identified cancer control projects through training, mentorship, and technical assistance (TA). The SWW program held a Symposium to provide in-person training on adapting, implementing, evaluating, sustaining, and scaling the three projects. We recruited 100% of US-Affiliated Pacific Island (USAPI) NCCCP programs (n=6), who made up approximately 26% of all programs that attended the Symposium (n=23). The USAPI jurisdictions face high cancer burden due, in part, to the United States nuclear legacy, the effects of climate change, limited medical infrastructure, and lack of culturally competent, centralized care across the almost 4,000 miles that the USAPI spans. Through the SWW program, USAPI recipients are supported in their ongoing efforts to mitigate cancer disparities affecting their communities. MethodsWe applied community-based participatory research methods and health equity principles to ensure the SWW program was relevant and responsive to the USAPI recipients’ contexts and needs. We created a SWW subcommittee to learn about and advocate for the specific needs of the USAPI. The committee spoke with ten clinicians and researchers with experience working in the USAPI, across four informal meetings, to understand the unique cancer prevention and control context of each USAPI jurisdiction. The committee reviewed USAPI cancer plans and extracted data related to SWW activities, including cancer prevention priorities, community partners, demographic characteristics, and healthcare infrastructure. Data were added to a matrix, coded, and summarized by subcommittee team members to develop a USAPI fact sheet. We shared the fact sheet with SWW Symposium facilitators and mentors to provide them with the necessary information to support the USAPI programs. Findings We identified components critical to providing effective training and TA that will support USAPI-led work to address disparities in cancer prevention and control. These components include 1) acknowledging the current and historical power dynamics that establish the USAPI cancer prevention and control program space, 2) adjusting generalized training content to each jurisdiction’s unique context and cancer prevention goals, 3) adapting communication strategies to USAPI programs’ preferences and time zones, 4) facilitating networking opportunities both between NCCCP USAPI jurisdictions and across all NCCCP recipients to build a SWW community of practice, and 5) establishing a sustained, bidirectional partnership between USAPI program leaders and the SWW team to collaborate on future cancer prevention and control projects and to provide training and TA, as needed. ConclusionsThe lessons learned from SWW regarding health equity and capacity-building can inform the efforts of researchers, evaluators, and training and TA providers working with USAPI jurisdictions, states, and territories engaged in cancer prevention and control work.

The Effects of Integrated Conditional Cash Transfers and Public Works Programs on Household Income Generation in Rural Tanzania

The Effects of Integrated Conditional Cash Transfers and Public Works Programs on Household Income Generation in Rural Tanzania

PARTICIPANTS’ PERCEPTIONS OF THE CONTRIBUTION OF THE EXPANDED PUBLIC WORKS PROGRAMME TO SUSTAINABLE LIVELIHOODS

Public Employment Programmes (PEPs), which include the South African Expanded Public Works Programme (EPWP), are widely recognised as important social protection tools that address the challenges of persistent unemployment and dire poverty. PEPs offer a ‘win-win’ policy option by creating jobs while simultaneously generating assets and delivering services. In South Africa, the impact of PEPs has primarily been evaluated based on employment opportunities, thus creating a gap in the comprehensive assessment of their contribution to the broader livelihood of participants beyond job creation. To address this gap, a qualitative research method was employed, utilising a snowball sampling strategy and the Sustainable Livelihoods Framework as the theoretical foundation for the investigation. The findings of this study underscore the positive contribution of the EPWP to the livelihoods of its participants. However, the study also uncovered various challenges confronting the programme, such as non-compliance with program regulations, such as payment below minimum wage rates and difficulties in meeting youth employment targets amidst escalating youth unemployment rates in South Africa. The research recommends introducing a national EPWP policy with enforcement mechanisms and youth-focused programmes while strengthening local institutions to provide services and processes to enhance the impact of these programs and create a conducive environment for beneficiaries to improve their livelihoods and escape poverty.

Critical Infrastructure in Historical Perspective: The Portuguese Railroad Network in the Second Half of the Nineteenth Century

In the 1850s, Portugal initiated an ambitious public works program spearheaded by railroads. In this article, I analyze how policymakers (congressmen, government officials, engineers, and military officers) debated and managed the construction and operation of the Portuguese railroad network using the theoretical framework of critical infrastructure. I show that railroads were deemed critical to modernize the country, draw it closer to the European core nations and further from the periphery, and to attract traffic to the Portuguese harbors. The absence of railroads was considered a vulnerability that could jeopardize Portugal as a nation and it fostered a sense of urgency that motivated policymakers to act, to a large extent, hastily. The construction of the network brought about other vulnerabilities that, for different motives, could threaten the future of the country. In a parallel way, the implementation of the system was marked by vulnerabilities that originated within or surrounding it, which limited its technical potential. Balancing between a literature review and the use of primary sources (parliamentary debates, technical reports, the press, and photography), I argue that the criticality associated with railroads, as a sociotechnical construction, was central to motivate their construction, but different vulnerabilities, inherent or external to the system, limited their influence and the advantages touted by its promoters.

Urban Public Works in Spatial Equilibrium: Experimental Evidence from Ethiopia

This paper evaluates a large urban public works program randomly rolled out across neighborhoods of Addis Ababa, Ethiopia. We find the program increased public employment and reduced private labor supply among beneficiaries and improved local amenities in treated locations. We then combine a spatial equilibrium model and unique commuting data to estimate the spillover effects of the program on private sector wages across neighborhoods: under full program rollout, wages increased by 18.6 percent. Using our model, we show that welfare gains to the poor are six times larger when we include the indirect effects on private wages and local amenities. (JEL H76, I38, J22, J31, O15, O18, R23)

Who Uses Childcare Centers? Evidence from Burkina Faso

What determines childcare center use for low-income urban households? And how does subsidizing provision change access to childcare services? We study these questions using data from a randomized evaluation that subsidized childcare center use for women participating in a public works program in Burkina Faso. One quarter of eligible women use these childcare services, tripling childcare center use for zero-to six-year-olds in our sample. Household wealth significantly predicts childcare center use. However, the public works childcare centers increased access for disadvantaged households and young children. Women employed as childcare providers were also more likely to use the childcare centers.

Impact Assessment of Government Funding for Subsistence, Smallholder Farmers, Communities, and Households on Food Security: An Advice for Extension Services

This study examined the impact of government funding on food security for subsistence farming, communities, households, and smallholder farmers in Frances Baard Municipality. Food insecurity has been a global phenomenon that has been on the increase since 2015, and it is thought to be a result of growing conflict, pandemic, and climate-related shocks. The analysis methods employed in this study were mainly cluster and discriminant analysis (DA). Simple random sampling techniques were used to select 533 farmers. The cluster analysis results reveal that Land Redistribution for Agricultural Development (LRAD) occupies the highest rank, followed by a Poverty Relief Programme and Land Restitution programme. In contrast, discriminant analysis (DA) results show that an Agricultural Starter Pack Programme is highly likely to increase the impact of food security in households when other interventions are held constant. The study concludes that to improve the food security of the Frances Baard Municipal District, the government should consistently improve the performance of these programmes. To improve the performance of these programmes, it is therefore recommended that the following programmes be resourced: the Agricultural Starter Pack Programme, Comprehensive Agricultural Support Programme (CASP), Expanded Public Works Programme (EPWP), Poverty Relief Programme (PRP), and Food Parcel Scheme (FPS).

Managing under austerity: a qualitative study of management–union relations during attempts to cut labour costs in three South African public hospitals

PurposeIn this paper, the authors examine the strategies used to reduce labour costs in three public hospitals in South Africa, which were effective and why. In the democratic era, after the revelations of large-scale corruption, the authors ask whether their case studies provide lessons for how public service institutions might re-make themselves, under circumstances of austerity.Design/methodology/approachA comparative qualitative case study approach, collecting data using a combination of interviews with managers, focus group discussions and interviews with shop stewards and staff was used.FindingsManagement in two hospitals relied on their financial power, divisions between unions and employees' loyalty. They lacked the insight to manage different actors, and their efforts to outsource services and draw on the Extended Public Works Program failed. They failed to support staff when working beyond their scope of practice, reducing employees' willingness to take on extra responsibilities. In the remaining hospital, while previous management had been removed due to protests by the unions, the new CEO provided stability and union–management relations were collaborative. Her legitimate power enabled unions and management to agree on appropriate cost cutting strategies.Originality/valueFinding an appropriate balance between the new reality of reduced financial resources and the needs of staff and patients, requires competent unions and management, transparency and trust to develop legitimate power; managing in an authoritarian manner, without legitimate power, reduces organisational capacity. Ensuring a fair and orderly process to replace ineffective management is key, while South Africa grows cohorts of competent managers and builds managerial experience.

Driver Safety High Cabin and Chassis Design in Diesel Forklifts

Purpose: In general, most forklift accidents occur due to rollover. After a rollover, the first affected part is the driver's cabin, followed by the chassis and parts. In the study, cabin and chassis designs of diesel forklifts with increased driver safety and performance were made.
 Methodology: Cabin and chassis tests were carried out with the Solid works program. According to the test results, the chassis and cabin design was made. Welding and assembly processes on the chassis of high-strength materials suitable for this design have been completed.
 Findings: As a result of the studies, the cabin design, which is different from other similar forklifts, notches on the edges of the fender, the removal of fuel and oil tanks from the chassis, eliminating the leakage test, and the steps on the sides of the chassis being made monolithic, are important innovations.
 Unique contributor to theory, policy and practice: As a result of all these studies, our KFD30 model was developed. This new model stands out with its new design and manufacturing on the forklift.

‘We need to stay alive’: ethnicisation and shortage of farm labour in Hungary

ABSTRACT This article fills a gap in the international academic literature, which has little to say on agricultural labour in Central and Eastern European countries and especially Hungary. The paper reveals factors that determine the ethnicisation and problematic availability of seasonal agricultural labourers in Hungary, made up mainly, but not exclusively of people of Roma ethnicity, largely Ukrainian or Romanian citizens from Hungarian minorities in Trans-Carpathia or Transylvania. The flexible oscillation of low-skilled labour across different economic sectors explains why a shortage peaked between 2016 and 2019 when, in addition to agriculture, the local states (through public works programmes) and industry (as post-crisis growth returned) competed for the same labour. The paper discusses findings from qualitative research, undertaken in an inner peripheral rural region, portraying the strategies and practices of local fruit-growing farmers to obtain labour, as well as diversify and mechanise. The study illustrates the mutual dependency of farmers and the local manual workforce. It is likely, however, that this mutuality will not last long: differentiation in farm structure will continue, some small orchards will disappear, large ones will become stronger and larger, and in doing so will not be able to avoid opting for migrant labour.

Exploring integrity in Australian public services: A method to benchmark public service codes of conduct

AbstractIntegrity is an ongoing concern in the public sector. Contemporary examples include fraud incidents, ethical violations, theft, and a disregard of legal advice resulting in significant harms to the public. Public service integrity management systems are interconnected frameworks of legislation and institutions intended to reduce such incidents, including Codes of Conduct (CoCs). A CoC is typically defined as a written set of norms that outline virtuous or desired behaviours, often creating or linking to sanctions for violations. Despite matters of integrity and corruption being a high concern for citizens, no method exists to compare monitoring, reporting, and review of CoCs across jurisdictions. We developed and applied a method to assess CoC implementation using specific assessment criteria developed by reviewing available content across jurisdictions and the current literature on CoCs and integrity management. Our results reveal substantial inconsistency between jurisdictions and a lack of available or accessible data for many CoC elements. Our method serves both as a tool for analysis of the effectiveness of CoCs over time and as an assessment of how jurisdictions are currently reporting on their compliance with their own CoCs.Points for practitioners A lack of evidence exists in terms of how CoCs are monitored, reported on, and reviewed. As a first stage of a research program, we develop and apply a method to all Australian states, territories, and the Australian Public Service to compare the monitoring, reporting, and review activities undertaken by these jurisdictions. Application of the method reveals opportunities for jurisdictions to improve the availability and accessibility of CoC data collection, reporting, and review. Auditors General and Public Accounts Committees should consider this method as part of their works programs and potentially use it to inform their scrutiny programs and requirements for performance and annual reporting. Public Service Commissions could find the data useful in adapting and improving their CoC monitoring, reporting, and review systems.

Social Protection and Foundational Cognitive Skills during Adolescence: Evidence from a Large Public Works Program.

Many low- and middle-income countries have introduced public works programs (PWPs) to fight poverty. This paper provides the first evidence that children from families who benefit from PWPs show increased foundational cognitive skills. The results, based on unique tablet-based data collected as part of a long-standing longitudinal survey, show positive associations between participation in the Productive Safety Net Programme (PSNP) in Ethiopia during childhood with long-term memory and implicit learning, and suggestive evidence for working memory. These associations appear to be strongest for children whose households were still PSNP participants in the year of data collection. Evidence suggests that the association with implicit learning may be operating partially through children's time reallocation away from unpaid labor responsibilities, while the association with long-term memory may in part be due to the program's success in remediating nutritional deficits caused by early-life rainfall shocks.

Application of audio spectrogram transformer machine learning model for audio tagging of construction activities

Major construction projects are approved based on an Environmental Impact Statement, which includes modeled predictions of noise impacts based on planned program. However, actual on site construction activities can differ significantly from planned works, resulting in modeled acoustic impacts (which have been used to mitigate impacts and inform stakeholders) out of date. A potential solution to this may be the use of machine learning models, to initially classify, and later predict, actual on site activities and commensurate impacts on nearby stakeholder and communities caused by site works. By leveraging emerging lower cost, smaller noise monitoring devices more data can be collected at receivers, and classified to determine the contributing sources of sound. SiteHive has worked with the University of Technology Sydney to design and develop a machine learning model to classify construction works in real-time on site, integrated as part of the SiteHive Hexanode multi-sensor environmental monitoring device. This presentation will showcase the design and development undertaken to date, and highlight results as tested as part of a major works program.

Gender and public works intervention in rural Ghana: An empowerment framework perspective

Transformative social protection requires an understanding of how interventions affect women and men. Gender inequality remains pervasive in societies. However, mainstream social protection evaluations have seldom been informed by gender analysis beyond sex categorisation. This paper focuses on the Labour Intensive Public Works Programme in Wa West District of Ghana to discuss the gender dynamics in participation outcomes. We analysed data from ten in-depth interviews with district assembly's social welfare and LIPW project staff and eight focus group discussions with programme participants and nonparticipants. In-depth interviews with the key informant clearly show that though the programme implementers acknowledge differential labour demands among participants, it is carried out in a manner that sustains gender inequalities through the endorsement of social stereotypes. The analysis revealed that an increase in women's income did not augment their ability to bargain in household decision-making. The study draws on Longwe's Women Empowerment Framework to discuss the results. This paper explains why and how this new knowledge can be used to inform theoretical and future policy debates on social protection.

Completing the Circle

IUPUI’s Center for Translating Research Into Practice (TRIP) and IUPUI University Library (Library) developed a partnership to enhance community access to faculty scholarship resulting from community-engaged and translational research. Library staff archive the scholarship of faculty affiliated with TRIP in IUPUI ScholarWorks, the campus’s open access institutional repository. The TRIP Scholarly Works Program was launched in 2013 and outcomes include benefits for faculty authors (increased readership) and for a world of readers (free access). After almost 10 years in existence, Library and TRIP staff sought to evaluate the success of this program. A survey was distributed to TRIP affiliated faculty to assess the impact of open access to their scholarship on their work as community-engaged and translational scholars. Faculty participants report a variety of benefits and yet, also indicate a need for increased program communication and fewer barriers to participation.

Remedial measures works programme for Slovenian motorway infrastructure

AbstractThe motorway infrastructure consists of pavements, bridges, tunnels, noise barriers, drainage systems, electro‐mechanical equipment and road furniture. All of them need to be at the adequate performance levels to ensure appropriate availability, comfort and safety. To fulfill this condition, road authorities must regularly carry out maintenance, rehabilitation and reconstruction works. As engineering structures have various service lives, performing remedial works for each individual structure at the optimal time would result in frequent road closures on the same road sections, significantly reducing the road availability for the users. Consequently, a works programme of remedial measures is needed which combines the measures on the same road section to the same time frame. The times planned for performing remedial measures therefore cannot be optimal for every structure in the road network, however they can be optimal from the road's availability and total costs perspective. An appropriate coordination between individual types of infrastructure, selection of measures and a method of merging these measures to the individual road sections must be performed. The paper discusses the integration of the results of individual management systems into a unified works programme.

Public-private partnerships: pro-cyclical or counter-cyclical? an empirical study

The use of public works programs to combat economic recessions is a recurring issue. In this paper we conducted an empirical analysis covering 160 countries (out of which 43 were retained) over 30 years, to determine to what extent it has been possible in the past to deploy PPPs as part of a wider countercyclical policy. The main criterion used in the analyses performed is the comparison between numbers and values of PPP projects reaching financial close during recessions and those outside a recession. The results are disappointing: only a handful of European countries have been successful. The only sensible approach, that works only in some developed nations, would be increasing the number of PPP projects while maintaining project size. This research contributes to the understanding of PPP adoption during economic recessions, sheds light on the different strategies of developed and developing countries, and emphasizes the challenges and opportunities associated with implementing countercyclical PPP policies. These insights can inform policymakers, practitioners, and researchers in their decision-making processes and contribute to the advancement of knowledge in the field of PPP project procurement and management.
