Abstract

The production of printed circuit boards (PCB) is facing considerable challenges concerning the demand for higher interconnection density and environmental friendliness. These demands cannot be satisfied by only optimising the conventional subtractive process chain, but require new production technologies to be developed. The production equipment has to guarantee that the process is carried out in a reliable way and at an acceptable speed. Therefore, the development of new process chains requires a critical review, or even a redesign of suitable manufacturing equipment. The application of simulation tools and “virtual prototyping” can support this process as the technology's impact on the machine design can be evaluated without the need for building costly prototypes. Finally, the costs of the new and current processes can be compared using the simulation results.

Abstract

This chapter utilizes German tax data to present evidence about the direct and indirect effects of new firm formation. Cohort analysis is applied to investigate survival, sales, inputs, and value added of start-up firms. Most dropouts occur in the early years. We show that start-up microenterprises increase economic vitality directly. Sales and value added are in an approximate proportion of 3:1. With respect to the indirect effects of new firms, we find that one Euro of sales induces considerable indirect effects because 66 Cents are used to buy products and services from incumbents. For this reason, new firms substantially promote economic prosperity of incumbents. Sectoral differences are also indicated, with the manufacturing industry generating highest sales and relying most heavily on inputs in the early periods.

Abstract

Assessment of personality disorders in substance abusing patients may produce important insights. Little is known about the value of routine personality disorder assessment in a clinical context. Adults with past‐year substance dependence seeking treatment at a centralised intake unit for substance abusers in the City of Copenhagen were randomised to assessment of personality disorders and individual psychoeducation vs. attention placebo (n=75). All patients received psychoeducation for attention deficit hyperactive disorder (ADHD) and anxiety/depression when indicated. Patients were followed at three and six months post‐treatment. The psychoeducation for personality disorder did not result in improved functioning. Significant differences indicated a larger drop in substance use in the experimental group. Assessing personality disorders and providing psychoeducation is a promising treatment in a clinical context. There is a need for relevant treatment options to improve functioning and quality of life for this group of patients.

Abstract

This report concerns itself with the process of change that has been underway in the city of Salford, concerning the adoption of a recovery‐oriented system of care. The paper contains the observations of the lead commissioner for drug treatment in Salford on the process of this change. The paper is influenced by William White's perspectives on recovery in Philadelphia and makes observations on their application in the British context. Finally, there is some discussion of whether this recovery approach constitutes a ‘paradigm change’ in UK drug policy. The information provided in this paper was gathered between January 2009 and July 2010. The methods included 12 initial unstructured interviews with service users self‐defined as ‘in recovery’, combined with two focus groups with seven service users and six members of staff. This initial work was then supplemented with three further focus groups conducted during the summer of 2009, involving 23 front line staff during the summer and autumn of 2009 and 52 consumer satisfaction questionnaires conducted prior to Christmas 2009. A further 40 semi‐structured interviews with service users who self‐defined as being in recovery were also concluded during the spring and summer of 2010.

Abstract

Purpose

This study aims to fabricate complex ceramic tetrahedron structures, which are challenging to produce by more conventional methods such as injection molding. To achieve this aim, thermoplastic-ceramic composite filaments were developed and printed with unmodified, consumer-grade, fused deposition modelling (FDM) printers instead.

Design/methodology/approach

Al2O3 ceramic powder was mixed with ethylene vinyl acetate polymer as a binder (50 Vol.- per cent) to form a filament with a constant diameter of 1.75 mm. After the printing and thermal treatment stages, the shrinkage and mechanical properties of cuboid and tetrahedron structures were investigated.

Findings

The shrinkage of the parts was found to be anisotropic, depending on the orientation of the printing pattern, with an increase of 2.4 per cent in the (vertical) printing direction compared to the (horizontal) printing layer direction. The alignment of the ceramic particle orientations introduced by FDM printing was identified as a potential cause of the anisotropy. This study further demonstrates that using a powder bed during the thermal debinding process yields sintered structures that can withstand twice the compressive force.

Originality/value

Ceramic FDM had previously been used primarily for simple scaffold structures. In this study, the applicability of ceramic FDM was extended from simple scaffolds to more complex geometries such as hollow tetrahedra. The structures produced in this study contain dense parts printed from multiple contiguous layers, as compared to the open structures usually found in scaffolds. The mechanical properties of the complex ceramic parts made by using this FDM technique were also subjected to investigation.

Abstract

Purpose

Ambulance services staff worldwide have long been at risk of encountering violence and aggression directed towards them during their work. Verbal forms of violence and aggression are the most prevalent form, but sometimes incidents involve physical injury, and on rare occasions homicides do occur. Exposure to such violence and aggression can have a lasting negative impact upon ambulance staff and has been associated with increased levels of stress, fear, anxiety, emotional exhaustion, depersonalisation and burnout syndrome. Despite the significance of this issue, little progress has been made to tackle it. The purpose of this paper is to describe this multi-agency approach being taken in Wales (UK) to reduce such harms from violence and aggression directed towards ambulance services staff.

Design/methodology/approach

An interpretative post-positivist narrative methodology and policy analysis approach was followed. Snowball methods of gathering data were used to construct this narrative involving meetings, telephone calls, review of policy documents, legislation and academic literature.

Findings

The authors report how tackling violence and aggression directed towards emergency workers has become a priority within Wales (UK), resulting in policy developments and initiatives from groups such as the UK and Welsh Government, the Welsh Ambulance Services National Health Services (NHS) Trust, Health Boards, the NHS Wales Anti-Violence Collaborative and the Joint Emergency Services Group (JESG) in Wales. This has included changes in legislation such as the Assaults on Emergency Workers (Offences) Act 2018 that came into force on 13th November 2018 and policy changes such as the obligatory responses to violence in health care and the JESG #WithUsNotAgainst Us campaign. Our study however reflects the complexity of this issue and the need for further high-quality research.

Originality/value

The experiences and activities of Wales (UK) reported in this paper adds to the international body of knowledge and literature on violence and aggression directed towards ambulance services staff.

Abstract

Purpose

Manufacturers seek to innovate and improve processes using new digital technologies. However, knowledge about these new technologies often resides outside a firm's boundaries. The authors draw on the concept of absorptive capacity and the literature on open innovation to explore the role of external search in the digitization of manufacturing.

Design/methodology/approach

The authors developed and distributed a survey to manufacturing firms in Switzerland, for which 151 complete responses were received from senior managers. The authors used multiple linear regressions to study the relations among the breadth and depth of external search, firms' adoption of digital technologies and operational performance outcomes.

Findings

External search depth was found to relate positively to higher adoption of computing technologies and shop floor connectivity technologies. No significant correlation was found between external search breadth and firms' adoption of digital technologies. Regarding performance outcomes, there is some evidence that increased adoption of digital technologies relates positively to higher volume flexibility, but not to increased production cost competitiveness.

Practical implications

Manufacturing firms that aim to digitize their processes can benefit from inbound open process innovation, but its utility varies for different clusters of digital technologies. Generally, the findings suggest that firms should build strong ties with a few external knowledge partners rather than surface relations with many.

Originality/value

This study contributes to the growing literature on the digitization of manufacturing with an analysis of the relation between firms' external search and their adoption of digital technologies. It adds early empirical insights to the literature on open process innovation.

Abstract

Purpose

The purpose of this paper is to test if companies with a greater concentration of management ownership (and thus more risk-averse managers) avoid less tax.

Design/methodology/approach

The authors use a regression analysis with panel data, using as a sample of Brazilian companies from 2001 to 2015. The authors investigate the impact of insider ownership on tax avoidance, testing how and how much different ownership levels of inside owner are associated with tax avoidance measured by effective tax rates and book-tax differences.

Findings

The results indicate that different levels of management ownership are associated with different levels of tax avoidance behavior.

Originality/value

This paper contributes to the literature showing that ownership and decision making are not always focused on only a few decision makers. The owners are likely to be more risk averse and therefore less willing to invest in risky projects such as tax avoidance.
