State of the Art in Directed Energy Deposition: From Additive Manufacturing to Materials Design

Additive manufacturing (AM) is a new paradigm for the design and production of high-performance components for aerospace, medical, energy, and automotive applications. This review will exclusively cover directed energy deposition (DED)-AM, with a focus on the deposition of powder-feed based metal and alloy systems. This paper provides a comprehensive review on the classification of DED systems, process variables, process physics, modelling efforts, common defects, mechanical properties of DED parts, and quality control methods. To provide a practical framework to print different materials using DED, a process map using the linear heat input and powder feed rate as variables is constructed. Based on the process map, three different areas that are not optimized for DED are identified. These areas correspond to the formation of a lack of fusion, keyholing, and mixed mode porosity in the printed parts. In the final part of the paper, emerging applications of DED from repairing damaged parts to bulk combinatorial alloys design are discussed. This paper concludes with recommendations for future research in order to transform the technology from “form” to “function,” which can provide significant potential benefits to different industries.
Two Essays on the Creation and Success of New Ventures

TWO ESSAYS ON THE CREATION AND SUCCESS OF NEW VENTURES Amirmahmood Amini Sedeh Old Dominion University, 2018 Director: Dr. William Q. Judge New venture creation is a complicated, idiosyncratic process that starts with an individual's ambition to exploit an opportunity and involves putting together resources to create value from the opportunity. During this journey, some entrepreneurs can initiate a new venture while others never exploit the discovered opportunity. Additionally, while many new ventures deploy the same resources, some entrepreneurial ventures are successful whereas others barely break even. Although extant literature acknowledges the importance of new venture creation, nonetheless, various drivers of innovative new ventures and factors facilitating the success of such ventures remain understudied. Given this gap in the literature, the first essay sheds light on drivers of innovative entrepreneurship, as the most productive type of entrepreneurship. Using a sample of 29,000 entrepreneurs in 62 countries, Essay 1 employs a multi-level model to investigate how entrepreneurs’ ability, motivation, and opportunity recognition (AMO) and their interaction with national institutions result in innovative new venture formation. Findings indicate that institutional voids appear to facilitate or hinder the human capital, opportunity actualization motivation, and opportunity seeking of founders of innovative, opportunity-based ventures. Essay 2, breaks new ground by examining entrepreneurial resource management strategies using a configurational approach. Building on a fuzzy-set analysis of more than 500 new ventures in the U.S., our research identifies five distinct configurations of resource structuring, bundling, and leveraging that collectively explain the profitability of entrepreneurial firms operating within both dynamic and stable industries. Results aim to uncover different resource management pathways that lead to the establishment of successful new ventures. Further, by illustrating that there are multiple successful paths that entrepreneurs can take, the findings indicate the equifinality of resource management strategies.
Portfolio Investment versus Foreign Direct Investment: A China-US Comparative Study

This paper investigates the costs and benefits of portfolio investment versus foreign direct investment (FDI) in a comparative study between China and the US. Recently, China‟s authorities have announced a plan to make the Reminbi fully convertible in the near future. This relaxation of the capital controls surely will benefit foreign firms, who are doing business with China and who want to transfer money easily from Chinese bank to a foreign bank. However, this raises the questions of whether or not the full convertibility benefits China. This paper shows empirical evidence that the US benefits much more from portfolio investment, which often rises sharply with full convertibility, than China does. In contrast China benefits much more from FDI, which can flourish without full convertibility, than the US does. The paper concludes that China might want to phase out its full capital convertibility slowly over time instead of implementing the process abruptly in the near future. Keywords: Capital controls, Capital liberalization, Currency convertibility, Investment
A Critical Analysis of Inter-Coder Reliability Methods in Information Systems Research

Qualitative researchers in business and management information systems fields often need to employ a method of inter-coder reliability to test the trustworthiness of the findings of their content analysis. A suitable method for checking the inter-coder reliability enables researchers to rigorously assess the degree of agreement among two or more independent qualitative coders. By employing this method, researchers can identify mistakes in the content analysis before the codes are used in developing and testing a theory or a measurement model and avoid any associated time, effort and financial cost. However, little guidance is available on what method of inter-coder reliability check should be used. In this paper, we present a critical analysis of these methods that are suitable for qualitative business and management IS research, and provide an example of how we employed the most rigorous method among these methods for a qualitative behavioural IS study.
The analysis of factors that effect business development and income of MSMEs in Denpasar city

The population in this study were all MSMEs players in the city of Denpasar, amounting to 30,840 MSMEs and the number of samples used as many as 100 MSME actors with a method of determining stratified proportional sampling. The data analysis technique used is path analysis. The results of the analysis show that: 1) capital, labor, and social capital have a positive and significant effect on the development of MSMEs in Denpasar City. This means that the availability of capital, the working hours of MSME actors and the application of the three dimensions of social capital namely trust, social norms, and social networks are very influential on the development of the MSME business sector. 2) Capital, labor, social capital, and business development have a positive and significant effect on the income of SMEs in Denpasar City. This means that capital ownership, labor, social capital and the development of MSMEs will have a positive and significant impact on increasing the income of MSME players. 3) Business development is a variable that mediates the influence of capital, labor and social capital on the income of SMEs in Denpasar City.
Does CPI Granger Cause WPI? Empirical Evidence From Threshold Cointegration and Spectral Granger Causality Approach in India

ABSTRACT:In this paper, we investigate the short run and long run causal relationship between wholesale price index (WPI) and consumer price index (CPI) in India over the period from 1994 April to 2015 August. Using a linear cointegration and a nonlinear time series model of threshold cointegration with asymmetric error correction model and spectral Granger causality approach, the study attempts to find the linear and nonlinear cointegration relationship between WPI and CPI in India. Empirical results reveal the non-existence of linear cointegration between the WPI and CPI indices in India. Moreover, using consistent threshold autoregressive (C-TAR) and consistent momentum threshold autoregressive (CM-TAR) model, we find the evidence of non-linear cointegration between WPI and CPI in India over the period from 1994 to 2015. The consistent M-TAR model indicates the presence of threshold cointegration between WPI and CPI, which further suggests the consistent inflationary trends after 1995 in India due to rising per capita income and other macroeconomic indicators. Furthermore, results indicate that WPI and CPI are cointegrated with threshold error correction adjustment, and the adjustment towards long-run equilibrium is asymmetric. This further suggests that WPI and CPI respond differently to positive and negative deviations from the long-run equilibrium after the threshold level. Empirical results further indicate that adjustment towards long-run equilibrium tends to persist more for negative deviations and respond more quickly towards positive deviations. The spectral granger causality results do not reveal the causality from WPI to CPI. However, the Granger causality from the asymmetric error correction model reveals the unidirectional causality, which indicates that CPI Granger causes WPI, support the demand-push inflation in India. CPI Granger causes WPI at very low and high frequencies, which takes an average wavelength of more than 3.6 quarters time in a year. Furthermore, empirical results reveal that WPI and CPI reach equilibrium asymmetrically after the threshold level of the two percentages. In sum, results suggest that the Indian policymakers can emphasis on the demand side rather than supply-side inflation to control the level of inflation after the desired threshold level. Moreover, the central bank of India would give importance to control the unwarranted inflationary trend, which has been caused due to the CPI-based demand-side inflation.

Towards On-Chip Continuous-Variable Quantum Key Distribution

The distribution of secret keys with information-theoretic security, made possible by the laws of quantum mechanics, is undoubtedly one of the main achievements of quantum information processing and communications. In recent years, quantum key distribution (QKD) has been implemented in real-world conditions and commercial systems are now available. Despite this progress, however, QKD remains a relatively difficult to operate and costly technology, hindering its widespread use for high-security applications. The photonic integration of QKD devices can play a crucial role in this direction by reducing their size and cost by several orders of magnitude.

Socio-economically Substantiated Education for Sustainable Development: Development of Competencies and Value Orientations Between Individual Responsibility and Structural Transformation

In this article, the concept of education for sustainable development is substantiated and expanded upon from a socio-economic perspective. Incorporating the concept of the economic citizen, we present the liberal republican civic ethos, moral judgement, decision-making capabilities and key competencies relevant for sustainability together with an informed understanding of economic context as constitutive elements of the educational concept. Against the backdrop of the limited reach of individual behavioural changes and the necessary reflections on structural questions, a heuristic of shared responsibility for sustainable development will be devised.
Housing Price and Household Debt Interactions in Sweden

Sweden is experiencing double-digit housing price gains alongside rising household debt. A common interpretation is that mortgage lending boosted by expansionary monetary policy is driving up house prices. But theory suggests the value of housing collateral is also important for household’s capacity to borrow. This paper examines the interactions between housing prices and household debt using a three-equation model, finding that household borrowing impacts housing prices in the short-run, but the price of housing is the main driver of the secular trend in household debt over the long-run. Both housing prices and household debt are estimated to be moderately above their long-run equilibrium levels, but the adjustment toward equilibrium is not found to be rapid. Whereas low interest rates have contributed to the recent surge in housing prices, growth in incomes and financial assets play a larger role. Policy experiments suggest that a gradual phasing out of mortgage interest deductibility is likely to have a manageable effect on housing prices and household debt.
Students' Beliefs and Attitudes Toward Learning in the Physics Component of the Lasallian (General Education) Core Curricu­lum

he Lasallian (General Education) Core Curriculum, im- plemented beginning Academic Year 2006-2007, aims to transform students’ beliefs, attitudes, and emotional reactions by providing opportunities for students to reflect on their learning experiences. This study documented the effect of the physics component of the new curriculum on students’ beliefs and attitudes by comparing the response profile of the freshmen of AY 2008-2009 with the response profile of the freshmen of AY 2005-2006 and AY 2006-2007. Pre- and Post-Course data was generated using the Maryland Physics Expectations Survey (MPEX) to determine students’ “cogni- tive expectations” – the student’s set of attitudes, beliefs, and assumptions about what sorts of things they will learn, what skills will be required, and what they will be expected to do in a physics class. Analysis of the results of the study re- vealed that the students moved towards an expert-like view in the Reality Link dimension and the Effort Link Dimension of the MPEX.
A home-based functional electrical stimulation system for upper-limb stroke rehabilitation

Due to an increased population of stroke patients and subsequent demand on health providers, there is an urgent need for effective stroke rehabilitation technology that can be used in patients' own homes. Over recent years, systems employing functional electrical stimulation (FES) have shown the ability to provide effective therapy. However, there is currently no low-cost therapeutic system available which simultaneously supplies FES to muscles in the patient's shoulder, arm and wrist to provide co-ordinated functional movement. This restricts the effectiveness of treatment, and hence the ability to support activities of daily living. In this thesis a home-based low cost rehabilitation system is developed which substantially extends the current state of art in terms of sensing and control methodologies. In particular, it embeds novel non-contact sensing approaches; the first use of an electrode array within a closed-loop model based control scheme; an interactive task display system; and an integrated learning-based controller for multiple muscles within the upper-limb (UL), which supports co-ordinated tasks. The thesis then focuses on compacting the prototype by upgrading the depth sensor and using embedded systems to transfer it to the home environment. Currently available home-based systems employing FES for UL rehabilitation are first reviewed in terms of their underlying technology, operation, scope and clinical evidence. Motivated by this, a detailed examination of a prototype system is carried out that combines low cost non-contact sensors with closed-loop FES controllers. Then potential avenues to extend the technology are highlighted, with specific focus given to low-cost non-contact based sensors for the hand and wrist. Sensing approaches are then reviewed and evaluated in terms of their scope to support the intended system requirements. Electrode array hardware is developed in order to provide accurate movement capability. Biomechanical models of the combined stimulated arm and mechanical support are then formulated. Using these, model-based iterative learning control methodologies are then designed and implemented. The system is evaluated with both unimpaired participants and stroke patients undergoing a course of treatment. Finally, a home-based prototype is developed which integrates and extends the aforementioned components. Results confirm the system's scope to provide more effective stroke rehabilitation. Based on the achieved results, courses of future work necessary to continue this development are outlined.
Gender in the editorial boards of scientific journals: a study on the current state of the art

Gender issues have been studied in a broad range of fields and in many areas of society, including social relations, politics, labour, and also academia. However, gender in the membership of editorial boards of scientific journals is a topic that only recently has started to attract the attention of researchers, and there is little literature on this subject as of today. The objective of this work is to present a study of the current state of editorial boards with regard to gender. The methodology is based on a literature review of gender issues in academia, and more specifically in the incipient field of gender in editorial boards. The main findings of this work, according to the reviewed bibliography, are that women are underrepresented in academic institutions, that this underrepresentation is increasingly marked in higher rank positions in academia and in editorial boards, and that this carries the risk of narrowing the nature and scope of the research in some fields of knowledge
Practising post‐humanism in geographical research

Post-humanist theories shaping contemporary geographic research have unsettled the privileged position of the ‘human’ as a common reference to apprehend social life. This decentring of the human demands that we rethink our expectations of, and approaches to, methodological practice and the traditional distinctions made between the theoretical and the empirical. In this introduction and the following interventions, we explore how a material situatedness and attention to nonhuman agencies within post-humanist thought complement and extend existing methodological innovations within human geography. We do so with reference to a series of Masters workshops – a somewhat overlooked space of research-creation – each of which explored the implications of post-humanism on methodological practice. The introduction concludes with three key tenets that were followed in each of the individual workshops, and which set out an ethos for practising post-humanism more broadly.
Inertial response analysis of PMSG-based WECS with VSG control

The inertial response of permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS) with virtual synchronous generator (VSG) control (WECS-VSG) is analysed in this paper. The differences between WECS-VSG and synchronisation generator (SG) are focused. For SG, the input active power is constant during inertial response stage. However, due to the control coupling between VSG and the other control function of WECS, the VSG active power reference value will change during the same stage. In order to understand the problem physically, the effective inertia of the WECS-VSG is deduced from the perspective of output equivalence. Based on the analyses of effective inertia, the authors know that the control coupling in WECS-VSG will weaken the VSG inertial response ability. Therefore it is a must to improve the WECS-VGS control realisation in the future study. All the analyses in this paper are verified by simulation results.
The framing effect among executive officers and board members

The objective of this study is to investigate the framing effect in the Brazilian corporate environment. Thus, this paper focuses on loss aversion related to different groups within organizations. Board members and executive officers are at first qualified, well prepared, and hold positions in which they are frequently called upon to decide, advise, or evaluate critical decisions. Interviews were held with executives, members of the Boards of Directors (henceforth simply board members) and Audit Committee members (henceforth AC members) from publicly traded companies listed on the São Paulo Stock Exchange (BMFBovespa). The results suggest that the framing effect occurs differently among AC members and the other respondents. With respect to the loss, 30.28% of the board members opt to spend 8% or more, however only 22.02% would do the same to avoid reducing a profit, a drop of 8.26 percentage points. This research contributes towards the field of behavioral finance by demonstrating how the framing effect manifests even among a group of experts. The main findings of this study suggest the presence of the framing effect even among qualified professionals.
