Abstract

Purpose

This paper aims to investigate the usability of the nickel copper zinc ferrite with the composition Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the realization of high-temperature multilayer coils as discrete components and integrated, buried function units in low temperature cofired ceramics (LTCC).

Design/methodology/approach

LTCC tapes were cast and test components were produced as multilayer coils and as embedded coils in a dielectric tape. Different metallization pastes are compared. The properties of the components were measured at room temperature and higher temperature up to 250°C. The results are compared with simulation data.

Findings

The silver palladium paste revealed the highest inductance values within the study. The measured characteristics over a frequency range from 1 MHz to 100 MHz agree qualitatively with the measurements obtained from toroidal test samples. The inductance increases with increasing temperature and this influence is lower than 10%. The characteristic of embedded coils is comparable with this of multilayer components. The effective permeability of the ferrite material reaches values around 130.

Research limitations/implications

The research results based on a limited number of experiments; therefore, the results should be verified considering higher sample sizes.

Practical implications

The results encourage the further investigation of the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 for the use as high-temperature ferrite for the design of multilayer coils with an operation frequency in the range of 5-10 MHz and operation temperatures up to 250°C.

Originality/value

It is demonstrated for the first time, that the material Ni0.4Cu0.2Zn0.4Fe1.98O3.99 is suitable for the realization of high-temperature multilayer coils and embedded coils in LTCC circuit carriers with high performance.

Abstract

Regulated differently in modern constitutions, emergency rule is a case of awkward, and dilemmatic, legal fine-tuning of an ambivalent political move that leads the executive of a democratic regime to the verge of the constitutional system. For that reason, as an utmost situation, emergency rule becomes a testing field for the resilience of the constitutional order. It affects its own foundations, the basic rights, and thus the constitutional capability to make possible their fulfilment. It also serves to appraise the workings of democratic regimes and, accordingly, the type of legitimacy derived from their institutional performance. Furthermore, it provides a vantage point to watch the reactions of both their representatives and their publics. Focussed on the COVID-19 pandemic, this chapter compares the cases of Germany and Spain through their legal regulations of emergency rule and their governments’ responses. Having rather analogous emergency legislations, from 2020 through 2022, there have been significant differences in their decision-making patterns.

Abstract

Education and employment are important elements of successful integration for immigrants in a host country. In Germany, young immigrants and members of the second immigrant generation have only limited access to higher education pathways and academic careers. Their trajectories are shaped mainly by the vocational training system, if they obtain any qualifications at all. Social risks for young people with immigrant backgrounds, and women in particular, such as being unemployed or having unstable careers, have frequently been pointed out by researchers, but little has been said about more qualified pathways available through privileged apprenticeships or academic qualifications. This article explores the social risks in trajectories of female immigrants following middle‐range or higher educational pathways in Germany. The cases discussed focus on young women who arrived in Germany during childhood or adolescence. The paper will first discuss the institutional settings of the German education system, focusing on their impact on pupils with immigrant backgrounds and how they overlap with existing gender inequalities in the recipient country. Discussion of the particular methodological approach will follow, before presentation of the findings of the case studies on female immigrants' transitions from education to work. The concluding discussion considers potential means to support participation in education and work for young women with immigrant backgrounds.

Abstract

Purpose

This paper aims to investigate the drivers of systemic risk and contagion among European banks from 2007 to 2012. The authors explain why some banks are expected to contribute more to systemic events in the European financial system than others by analysing the tail co-movement of banks’ security prices.

Design/methodology/approach

First, the authors derive a systemic risk measure from the concepts of marginal expected shortfall and conditional value at risk analysing tail co-movements of daily bank stock returns. The authors then run panel regressions for the systemic risk measure using idiosyncratic bank characteristics and a set of country and policy control variables.

Findings

The results comprise highly significant drivers of systemic risk in the European banking sector with important implications for research and banking regulation. Using a set of panel regressions, the authors identify bank size, asset and income structure, loss and liquidity coverage, profitability and several macroeconomic conditions as drivers of systemic risk.

Research limitations/implications

Analysing the tail co-movement of security prices excludes a number of “smaller” institutions without publicly listed securities. The other shortfall is that we do not assess the systemic impact of non-bank financial institutions.

Practical implications

Regulators have to consider a broad variety of indicators for assessing systemic risks. Existing microprudential-oriented rules are less effective, and policymakers may consider new measures like asset diversification to mitigate systemic risks in the banking system.

Originality/value

The authors contribute to existing empirical analyses in three ways. First, they propose a method to identify systemically important banks (SIBs). Second, they develop two measures to assess their potential negative impact on the system. Third, they contribute to the closing of the research gaps by analysing which macroprudential regulations for SIBs are most effective without hampering free market forces.

Abstract

When the German armed forces came into being in the mid-1950s, as a result of the international tensions due to the Cold War, few considered female soldiers. It took another decade until this issue began to be discussed in society and in politics. This discussion of the 1960s was shaped by a wide-ranging democratisation and significant socio- and politico-cultural changes. Starting with the so-called student movement, various parts of German society became important social movements that called for political and societal participation. Among these were various women's movement groups that criticised the patriarchically structured German society and sought emancipation and gender equality as laid out in various UN documents. Of course, during this endeavour, some parts of them also demanded equal access and participation to professions that had hitherto been male-exclusive domains. Shortly thereafter, the male-dominated soldierly profession and the Bundeswehr viewed pressure from society, which soon translated into the political sphere and put the issue of women in the military on the agenda (Kraake, 1992; Albrecht-Heide & Bujewski-Crawford, 1991; Fischer, 1997).

Abstract

Purpose

The purpose of this paper is to analyse the symbolic forms used in selected mainstream management models and to assess whether it would be expedient for enforcing the connection between leadership and individual human reality if such management models were fundamentally inspired by a successful manager and artist.

Design/methodology/approach

The theoretical starting point of this article is Cassirer's philosophy on symbolic forms. The paper analyses the symbolic forms embedded in the management discourse practice of art in the way that the concept is practiced by Kasper Holten, the highly successful Artistic Director of the Royal Danish Opera.

Findings

The analysis shows that conventional management control models are rooted in the symbolic form of science, but are at risk of getting caught in assumptions of the form gliding into the symbolic form of religion and myth, where all the forms tend to oppress essential aspects of individuality. Kasper Holten integrates the symbolic forms of art and science, which makes him capable of binding to the individual's life‐world.

Research limitations/implications

Analysing Kasper Holten's views on management reveals features and structures for a new management discourse practice which is far better suited to most of the knowledge jobs in contemporary society than the more conventional management discourse.

Originality/value

The paper provides novel insight into the interrelationship between the specific way of using language and the way of managing and constructing a world. It paves the way for another way of doing management control and accounting.

Abstract

Purpose

Criminalization of drug use in Malaysia has concentrated people who inject drugs (PWID) and people living with HIV into prisons where health services are minimal and HIV-related mortality is high. Few studies have comprehensively assessed the complex health needs of this population. The paper aims to discuss these issues.

Design/methodology/approach

From October 2012 through March 2013, 221 sequentially selected HIV-infected male prisoners underwent a comprehensive health assessment that included a structured history, physical examination, and clinically indicated diagnostic studies.

Findings

Participants were mostly PWID (83.7 percent) and diagnosed with HIV while incarcerated (66.9 percent). Prevalence of hepatitis C virus (90.4 percent), untreated syphilis (8.1 percent), active (13.1 percent), and latent (81.2 percent) tuberculosis infection was several fold higher than non-prisoner Malaysian adults, as was tobacco use (71.9 percent) and heavy drinking (30.8 percent). Most (89.5 percent) were aware of their HIV status before the current incarceration, yet few had been engaged previously in HIV care, including pre-incarceration CD4 monitoring (24.7 percent) or prescribed antiretroviral therapy (ART) (16.7 percent). Despite most (73.7 percent) meeting Malaysia’s criteria for ART (CD4 <350 cells/μL), less than half (48.4 percent) ultimately received it. Nearly one-quarter (22.8 percent) of those with AIDS (<200 cells/μL) did not receive ART.

Originality/value

Drug addiction and communicable disease comorbidity, which interact negatively and synergistically with HIV and pose serious public health threats, are highly prevalent in HIV-infected prisoners. Interventions to address the critical shortage of healthcare providers and large gaps in treatment for HIV and other co-morbid conditions are urgently needed to meet the health needs of HIV-infected Malaysian prisoners, most of whom will soon transition to the community.
