The purpose of this paper is to propose a casting process for the production of double-chamber soft fingers, which avoids the problems of air leakage and fracture caused by multistep casting. This proposed method facilitates the simultaneous casting of the inflation chamber and the jamming chamber.

An integrated molding technology based on the lost wax casting method is proposed for the manufacture of double-chamber soft fingers. The solid wax core is assembled with the mold, and then liquid silicone rubber is injected into it. After cooling and solidification, the mold is stripped off and heated in boiling water, so that the solid wax core melts and precipitates, and the integrated soft finger is obtained.

The performance and fatigue tests of the soft fingers produced by the proposed method have been carried out. The results show that the manufacturing method can significantly improve the fatigue resistance and stability of the soft fingers, while also avoiding the problems such as air leakage and cracking.

The improvement of the previous multistep casting method of soft fingers is proposed, and the integrated molding manufacturing method is proposed to avoid the problems caused by secondary bonding.

In this paper, the authors examine the causes of 2021–2023 inflation and evaluate whether raising interest rates is the right solution.

The authors evaluate both the macroeconomic (too much demand) and microeconomic (monopoly pricing and supply chains) explanations for the causes of inflation.

The authors argue that the spike in inflation is due to disrupted supply chains and corporations taking advantage of the situation to raise their prices. The aggregate demand stimulus from fiscal policy had all but played out by the time inflation arose, making it an unlikely cause of said inflation.

The authors' paper demonstrates that raising interest rates is the wrong solution to tackling the problem of inflation, especially since it's coming from the supply side.

Inflation and federal monetary efforts to control it with interest rate hikes have very real and overwhelmingly negative consequences on US local governments following the onset of COVID-19. This study explores the post-pandemic inflationary environment of US local governments; examines the impacts of inflation and high interest rates on local government revenue, operating costs, capital costs, and debt service; reviews local government inflation management strategies, including the use of intergovernmental revenue; and assesses ongoing threats to local government financial health and financial resilience.

This study uses trend and literature analysis to comment on current issues local governments face.

The study finds that the growth of property values and resulting stability of property tax revenue has been important to local government revenues; that local governments bear very real burdens as operating and capital costs increase; and that the combination of high inflation and interest rates affects local government debt issuance by negatively affecting credit quality and interest costs, leading to municipal market contraction. Local governments have benefitted tremendously from intergovernmental revenue, but would be ill-advised to rely on it.

Vulnerabilities owing from revenue mismatch with the economy; inadequate affordable housing, inequality, and social issues; a changing workforce and tight labor market; climate change; and federal fiscal contraction—all of which are exacerbated by high inflation and interest rates—require local governments to act strategically, boldly and collaboratively to achieve fiscal health and financial resilience, and to realize positive returns of investments in people and capital.

This work is unique in addressing the post-pandemic impact of inflation and interest rates on local governments.

Alexandre Tombini, the governor of the Central Bank of Brazil, faced a difficult situation in July 2015. Inflation was in the double digits, well above the target rate of 4.5%, and unemployment had increased from around 4.5% a year prior to nearly 8%. Any actions Tombini took to control inflation would most likely exacerbate unemployment, at least in the short run. To further complicate matters, Tombini's office was not independent of the executive branch of Brazil's government, and Tombini faced the possibility that any of his actions that were not aligned with the priorities of the current administration could cost him his job.

This case follows classes on fiscal and monetary policy in normal times and is the first class in a sequence on macroeconomic challenges–in this case, stagflation–high inflation and high unemployment. Students are pushed to consider why macroeconomic stabilization involves such acute and unpleasant tradeoffs during episodes of high inflation and unemployment. Students use the IS/LM AD/AS model as a reference.

Inflation expectations are an important part of the transmission mechanism of the inflation targeting regime. As such, central bankers must study the inflation expectations of economic agents to anchor them close to the level of the inflation target. However, economic agents are affected by the past and current macroeconomic situation when they form their expectations concerning future inflation. Using survey data on inflation expectations in Czechia, we investigate the macroeconomic determinants of Czech analysts' and managers' inflation expectations. We find that both actual and past inflation have a substantial impact on inflation expectations of the agents surveyed. We also identify backward-looking behaviour among these agents: persistence in inflation expectations of up to two quarters was detected. Moreover, financial analysts formed inflation expectations more in line with economic theory, while company managers evinced expectations similar to those of consumers.

The paper uses key themes from Fox’s writing to reflect on the wave of public sector industrial action that developed in the UK since the early 2020s: specifically the relevance of (1) radical pluralism, (2) historical context, (3) understanding the effects of high inflation and (4) (a breakdown of) trust relations.

The paper draws primarily on evidence from broad public debate but is informed by discussions held with senior union leaders both for a research project and in delivering development training.

Radical pluralism is used as a lens through which to understand declining trust in institutions of pluralist collective industrial relations in the UK public sector, arguing that current developments need to be understood in historical context. An analysis of the industrial action in the early 2020s highlights the ways that a period of high inflation can stress institutions of collective employment regulation, rendering visible the limits of conventional, pluralist industrial relations.

The paper could be extended by more detailed empirical data collection, both in the UK and other national institutional contexts.

Unions need to more consistently focus on issues of power. A stronger focus on power might identify the limitations of pluralist institutions of collective regulation and embed a commitment to building union influence to challenge those existing structures in favour of mechanisms to build workers' power more broadly.

Understanding these disputes as, at least in part, being about the limits to and undermining of trust in collective institutions that regulate work and employment allows us to better understand the forces at play and potential outcomes of these disputes.

The paper makes three key contributions: first, applying Fox’s work in a practical way to contemporary UK industrial relations; second, extending his analyses to public sector industrial relations and third, arguing that power needs to be more centrally located within union objectives in order to reshape industrial relations to radical pluralist ends.
