The purpose of this paper is to show the innovative approach of manufacturing filigree and highly complex components by means of laser beam melting.

The paper describes the unique geometric freedom of the laser beam melting technology and its possibility of quick, tool‐less production of complex components allow the manufacturing of functionally superior components in a short time.

Principally concludes the following: additive manufacturing proved to give superior properties to the component compared to conventional manufacturing methods.

This study provides context for the development and manufacturing of an individual heat‐transfer component for an electric‐driven formula race car.

The levels of work-related stress and the incidence rates of subsequent related illnesses are increasing in our society, leading to high individual and socioeconomic burdens. Mindfulness training has been shown to be an effective method of improving stress resilience. This paper aims to investigate the efficacy of nature-based mindfulness training in professionals with high levels of work-related stress.

In this controlled pilot study, a total of 56 volunteers completed a nature-based mindfulness training progam and were compared to 8 participants (waitlist controls). Psychometric assessments were performed at baseline and after two and four months of training.

After two months of training, the scores for self-efficacy, sense of coherence, level of mindfulness and overall psychiatric symptom load had significantly improved in the intervention group, while the control group did not show any significant improvements. A comparison between the intervention and control groups showed a significant difference regarding the sense of coherence only.

Since this was an exploratory study with a small control group, further studies are needed to verify our findings.

In conclusion, nature-based mindfulness training seems to be a promising tool for the improvement of resilience and overall psychological health in professionals.

This was the first study to systematically investigate effects of nature-based mindfulness training in people with high work-related stress.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Adventure activities have become the core products of many tourism destinations. Hiking, which is known to be a soft adventure activity, represents an especially important product for many tourism destinations around the globe and in the European Alps. However, little research has explored hikers’ underlying motivation and experiences, which are expected to differ from the hard adventure context, as mountain hiking provides a low risk, but high immersion. This paper aims to determine and explore the underlying dimensions and dynamics of mountain hikers’ soft adventure motivation (SAM).

A concurrent mixed-method design that builds on a quantitative survey (N = 379) and qualitative interviews (N = 14) was used to explore SAM factors. This study combined exploratory factor analysis and regression analysis with semi-structured interviews and template analysis.

The quantitative results provide six SAM factors and emphasize that “relaxation,” “socializing” and “discovery” contribute to hiking satisfaction, while “recognition” has adverse effects. By triangulating these findings with hikers’ experiences, this study underlines the associated recreational meaning of hiking and provides an in-depth qualitative discussion of SAM factors and the subordinate role of “recognition.”

The contribution of this paper is a refined understanding of SAM in the hiking context by emphasizing the recreational meaning of mountain hiking. As a result, this study adds an important missing link to previous outdoor tourism and leisure studies by showing the special composition and dynamics of SAM. The findings also support the creation of tailor-made touristic products.

探险活动已经成为许多旅游目的地的核心产品。其中徒步旅行被认作为一种“轻松”探险活动并且代表着全球众多旅游目的地及欧洲阿尔卑斯山的重要产品。然而, 很少有研究探索远足者的潜在动机和经验, 由于徒步远足的风险较低, 但参与感高, 因此预计于艰苦的冒险环境有所不同。因此, 本文确定并探索了山地徒步者“轻松”冒险动机的潜在维度和动力。

采用基于定量调查(N = 379)和定性访谈(N = 14)的并行混合方法设计来探索SAM因素。因此, 我们将探索性因子分析和回归分析与半结构化访谈和模板分析相结合。

定量结果提供了6个SAM因素, 并强调“放松”、“社交”和“发现”有助于提升满意度, 而“认知”则有负面影响。通过将这些发现与徒步旅行者的经历进行三角分析, 我们强调了徒步旅行的相关娱乐意义, 并对SAM因素和“识别”的从属作用进行了深入的定性讨论。

本文的贡献在于通过强调登山的休闲意义, 对徒步情景下的SAM进行了精细化的理解。因此, 我们通过展示SAM的特殊组成和动态, 为之前的户外旅游和休闲研究添加了一个重要的缺失环节。最后, 研究结果支持了定制旅游产品的创造。

Las actividades de aventura se han convertido en uno de los productos principales de muchos destinos turísticos, especialmente el senderismo, una actividad de aventura de baja dificultad que representa un producto importante para muchos destinos turísticos alrededor del mundo y en los Alpes europeos. Sin embargo, pocas investigaciones han estudiado la motivación y las experiencias subyacentes de los excursionistas, las cuales se espera que difieran del contexto de aventura de alta dificultad, ya que el senderismo de montaña proporciona un bajo riesgo pero una alta inmersión. Por lo tanto, este documento determina y examina las dimensiones y dinámicas subyacentes de la motivación de aventura de baja dificultad (SAM, por sus siglas en inglés) de los excursionistas de montaña.

Se utilizó un diseño de método mixto concurrente que se basa en una encuesta cuantitativa (N = 379) y entrevistas cualitativas (N = 14) para explorar los factores de SAM. De este modo, se combinó análisis factorial exploratorio y análisis de regresión con entrevistas semiestructuradas y análisis de plantillas.

Los resultados cuantitativos aportan seis factores de SAM y enfatizan que la “relajación”, la “socialización” y el “descubrimiento” contribuyen a la satisfacción del senderismo, mientras que el “reconocimiento” tiene efectos adversos. Al relacionar estos hallazgos con las experiencias de los excursionistas se destaca el significado recreativo asociado al senderismo y se brinda una discusión cualitativa profunda de los factores de SAM y el papel subordinado del “reconocimiento”.

La contribución de este artículo es una comprensión refinada de la SAM en el contexto de senderismo al enfatizar el significado recreativo del senderismo de montaña. De este modo, se suma un importante eslabón perdido a los estudios anteriores de turismo al aire libre y de ocio al mostrar la composición y dinámica especial de la SAM. Por último, los resultados respaldan la creación de productos turísticos hechos a la medida de las preferencias de los turistas.

After some introductory words about the preeminence of German accounting research during the first half of the 20th century, the paper offers a survey of the most important theories of accounts classes that still prevailed during the first two decades or longer. Following World War I, the issue of hyperinflation in Austria and Germany stimulated a considerable amount of original accounting research. After the inflationary period, a series of competing Bilanztheorien, discussed in the text, dominated the scene. Two figures emerged supremely from this struggle. The first was Eugen Schmalenbach, with his “dynamic accounting”, a series of further important contributions to inflation accounting, to the master chart of accounts, to cost accounting, and to other areas of business economics. The other scholar was Fritz Schmidt, with his organic accounting theory that promoted replacement values and his emphasis on the profit and loss account, no less than the balance sheet. The gamut of further eminent personalities, listed in chronological order, contains the following names: Schär, Penndorf, Leitner, Gomberg, Nicklisch, Rieger, Prion, Osbahr, Passow, Dörfel, Sganzini, Walb, Calmes, Kalveram, Meithner, Lion, Töndury, Mahlberg, le Coutre, Geldmacher, Max Lehmann, Leopold Mayer, Karl Seidel, Alfred Isaac, Mellerowicz, Seyffert, Beste, Gutenberg, Käfer, Seischab, Kosiol, Münstermann, and others. Separate Sections or Sub‐Sections are devoted to charts and master charts of accounts in German accounting theory, as well as to cost accounting and the writing of accounting history.

The purpose of this paper is to reconstruct the development of industrial relations (IR) in Germany since the end of the Second World War and discusses the current challenges posed by economic globalisation und European integration.

Combining a political economy, identifying Germany as a coordinated market economy (social market economy), and actor-centred historical institutionalism approach, outlining the formation and strategies of the main social actors within a particular institutional setting, the paper draws on the broad range of research on IR in Germany and its theoretical debates, including own research in the field.

The legacy of the key institutional settings in the post-war era – primarily the social market economy, co-determination at supervisory boards, works councils and sector-based non-ideological unions with their analogously organised employer counterparts, as well as the dual system of interest representation – has shaped the German IR and still underlie the bargaining processes and joint learning processes although trade unions and employers’ associations have been weakened because of loss of membership. In consequence the coverage scope of collective agreements is now somewhat reduced. Despite being declared dead many times, the “German model” of a “conflictual partnership” of capital and labour has survived many turbulent changes affecting it to the core.

The paper presents an original, theoretical informed reconstruction of the German IR and allows an understanding of the current institutional changes and challenges in the light of historical legacies. Additionally the theoretical debates on path dependence and learning processes of collectivities are enriched through its application to the German case.

Members of Congress become involved in scandals on a regular basis. These range from personal imbroglios, like sexual affairs or substance abuse, to professional scandals like embezzlement of campaign funds, abuse of office, or insider trading. As a common feature of congressional life, scholars have shown that scandals frequently disrupt the electoral and legislative trajectories of representatives' careers.

However, it must be remembered that congressional offices are comprised of more than just an individual member. Congressional offices are legislative enterprises, and a representative's staff are integral to his or her political and lawmaking activities. Accordingly, studying how scandals relate to the careers of congressional staff is an important but overlooked topic.

In this chapter, the authors investigate the relationship between members' malfeasances and the careers of the staff around them. The authors combine a list of congressional scandals with a dataset that captures the turnover of staff in congressional offices. The chapter proceeds in four parts. First, the authors describe the structure of a congressional office and the relationship between members and their staff. Next, the authors provide an overview of scandals in Congress and what previous literature has uncovered about their effects. Third, the authors examine staffing patterns and turnover in offices hit by scandal, uncovering evidence that scandals are associated with staff departures. The authors end by considering how Congress as an institution could help to protect and support employees who are caught up in a member's poor choices.

In September 2015, VW had admitted to United States regulators that it had deliberately installed “defeat devices” in many of its diesel cars, which enabled the cars to cheat on federal and state emissions tests, making them able to pass the tests and hit ambitious mileage and performance targets while actually emitting up to 40 times more hazardous gases into the atmosphere than legally allowed. The discovery had prompted the U.S. Environmental Protection Agency (EPA) to halt final certification of VW’s 2016 diesel models, and VW itself had halted sales of its 2015 models. As fallout from the defeat devices developed, VW posted its first quarterly loss in more than 15 years, and its stock plummeted. Top executives were replaced, and VW abandoned its goal of becoming the world’s largest automaker. Stakeholders around the world had been asking since the scandal broke: “How could this have happened at Volkswagen?”
