Abstract

In this article the author discusses two alternative approaches to the valuing of non‐maturity deposits. He examines both the replication of cash flows and behavioural modelling and analyses the various other factors which should be taken into account.

Abstract

Purpose

Drawing on the overarching framework of social capital theory, the purpose of this paper is to develop and empirically examine networking behaviour and employability within the higher education context.

Design/methodology/approach

In a sample of 376 full-time business students the authors measured perceived employability, networking behaviour, access to information and resources and job-search learning goal orientation (JSLGO).

Findings

The authors found networking is related to increased internal and external perceived employability by boosting access to information and resources. The results also demonstrate that networking is positively related to access to information and resources for low and high JSLGO, the relationship being stronger for those with higher levels.

Research limitations/implications

The results provide an enriched view of individual networking behaviour by offering an indirect model of networking outcomes and to the graduate employability and social capital literatures.

Practical implications

The findings may provide focus for individuals concerned with enhancing their employability and those involved in supporting career guidance.

Originality/value

Obvious beneficiaries are students, for whom employment is a key concern, and universities who face increasing pressure to enhance graduate employability whilst resources to do so are diminishing. To this end the authors highlight activities that may develop networking behaviours and JSLGO.

Abstract

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.

Abstract

Purpose

The purpose of this paper is to develop, apply and validate a mesh-free graph theory–based approach for rapid thermal modeling of the directed energy deposition (DED) additive manufacturing (AM) process.

Design/methodology/approach

In this study, the authors develop a novel mesh-free graph theory–based approach to predict the thermal history of the DED process. Subsequently, the authors validated the graph theory predicted temperature trends using experimental temperature data for DED of titanium alloy parts (Ti-6Al-4V). Temperature trends were tracked by embedding thermocouples in the substrate. The DED process was simulated using the graph theory approach, and the thermal history predictions were validated based on the data from the thermocouples.

Findings

The temperature trends predicted by the graph theory approach have mean absolute percentage error of approximately 11% and root mean square error of 23°C when compared to the experimental data. Moreover, the graph theory simulation was obtained within 4 min using desktop computing resources, which is less than the build time of 25 min. By comparison, a finite element–based model required 136 min to converge to similar level of error.

Research limitations/implications

This study uses data from fixed thermocouples when printing thin-wall DED parts. In the future, the authors will incorporate infrared thermal camera data from large parts.

Practical implications

The DED process is particularly valuable for near-net shape manufacturing, repair and remanufacturing applications. However, DED parts are often afflicted with flaws, such as cracking and distortion. In DED, flaw formation is largely governed by the intensity and spatial distribution of heat in the part during the process, often referred to as the thermal history. Accordingly, fast and accurate thermal models to predict the thermal history are necessary to understand and preclude flaw formation.

Originality/value

This paper presents a new mesh-free computational thermal modeling approach based on graph theory (network science) and applies it to DED. The approach eschews the tedious and computationally demanding meshing aspect of finite element modeling and allows rapid simulation of the thermal history in additive manufacturing. Although the graph theory has been applied to thermal modeling of laser powder bed fusion (LPBF), there are distinct phenomenological differences between DED and LPBF that necessitate substantial modifications to the graph theory approach.

Abstract

The Baumol effect follows from simple but deep microeconomic reasoning. All prices are relative prices, so if some goods are getting cheaper, others must be getting more expensive. Simple. But in transferring our attention about the cause of rising prices from stagnating sectors to progressive sectors, the Baumol effect radically changes our understanding of the causes, consequences, and evaluation of rising prices. Even today, the power of the Baumol effect to explain price changes through different time periods and places is underestimated. Throughout his career, Baumol returned to this simple idea many times, making it a key to his thought and his evolving views on long-term economic development.

Abstract

This chapter presents two case studies to address the challenge of how students in large, diverse classes can become effectively engaged in their learning through the support of technology. Implementation of two modules in the University of Exeter Business School is explored: a first-year management module wherein students make use of camcorders and a master's module where students use wikis. Each has been important in coming to understand the inter-relationship of pedagogic processes and technology use, in particular in the context of group work. Data on student outcomes and perceptions have been collected through ongoing monitoring, individual and group reflective accounts, tutor and student-led surveys and informal verbal feedback. Overall, the use of both technologies is highly valued by most students and by the teachers, despite the many (and sometimes unexpected) difficulties associated with their management. The main benefits are in the way that they can be used to support attendance, group cohesion and quality of work, in an ethos where the importance of group work is central to learning and where individuals are recognised for what they can contribute despite the large cohort size and the many different nationalities.
