Thread Structure

This study aims to show the impact of both the width of the base of the spinning triangle and the production speeds of hollow-spindle spinning machines on the structure of ultimate multiple-thread-structure bouclé yarns and similar fancy yarns. A hollow-spindle spinning machine was used and bouclé yarns were made of a core thread, an effect thread and a (multifilament) binder. Initially, five bouclé yarns were made by setting the widths of the base of the spinning triangle at five levels, i.e. 4.5 mm, 7.5 mm, 10 mm, 13 mm and 16 mm. A further six bouclé yarns were made to show the changes that occur to the spinning triangle at various production speeds. The resulting fancy bouclé yarns were assessed by measuring the size, number and circularity ratio of bouclé profiles. It was found that at low production speeds, i.e. at start-up, that the spinning triangle was unstable, which adversely affected the structure of the final bouclé yarns. However, at production speeds higher than 17 m/min, the spinning triangle became stable, though such a stable spinning triangle had no impact on the structure of the resulting fancy bouclé yarns. The results of this study may help fancy yarn manufacturers to avoid making defective fancy yarns.

The Impact

This study examines the relationships between the structure of fancy bouclé yarns and the bending stiffness of the input threads that are used to make those fancy yarns. Four fancy bouclé yarns and an extra two confirmation bouclé yarns were made to test the impact of the bending stiffness of the effect input threads. Six fancy yarns were made to test the impact of bending stiffness of the core thread on the fancy yarn structure. The structure of the fancy yarn was defined by the number of fancy profiles, the size of fancy profile, the circularity ratio of fancy profile and the shape factor of fancy yarn. It was found that increasing the value of the stiffness of the effect thread increased the size of fancy profile but decreased both the number of fancy profiles and the shape factor of fancy yarn. Those relationships were represented by regression models that were significant at α = 0.10. The deviation between the theoretical values and the real values was −14.39% and 2.07%. Further, up to a value of 8.636 g mm2, the bending stiffness of the core thread appeared not to have an effect on the structure of the fancy yarns. This study is important as it is the first that accounts statistically for the impact of bending stiffness of the input threads on the structure of the resultant fancy yarns. Therefore, it aids fancy yarn manufacturers when designing fancy yarns with predicted structures.

The Impact

Audited financial statements can be viewed as the product of negotiations between a company's management and its auditor. Relative power of these two parties is a major factor that determines the outcome of the negotiation. This study examines the impact of auditor tenure, importance of a client to an audit partner, nonaudit purchases, and prior audit firm experience of client personnel on client perceptions about their ability to persuade the auditor in the context of an accounting disagreement. We obtained responses to a survey from 124 CPAs in industry who are employed as CEOs, CFOs, controllers, or treasurers. Our results indicate that respondents from companies with short auditor tenures were somewhat more likely to indicate that they could persuade the auditor to accept their (client's) position in case of a disagreement. This finding is consistent with the argument that auditors are susceptible to influence in the early years as they are still in the process of recouping start-up costs, but is not consistent with concerns expressed by legislators and others that long auditor tenures will adversely affect audit quality. Respondents who believed their business was more important for the audit partner were also more likely to believe that they could persuade the auditor. However, the purchase of nonaudit services and prior audit experience were not related to client's perceptions about their ability to persuade the auditor.

AbstractThis research focuses on how entrepreneurs utilize cronyism to acquire resources. A case study method allowed us to explore three firms in the private property development industry in China. These firms uniquely cultivated cronyism and achieved distinctly different outcomes. Our findings highlight Chinese entrepreneurs in start-up ventures and later-stage enterprises employ cronyism. The underlying rationale for using cronyism have common and heterogeneous motivations. The similarity and distinguishing rationale also apply to the impact of cronyism. We also find two contingency working mechanisms for cronyism: entrepreneurial characteristics and a staged model for cronyism. With the firm’s growth, cronyism remains important, but firms with more community involvement outperform others. This research contributes to the theory on strategic network utilization for resource acquisition during entrepreneurial development stages. We investigate how entrepreneurial strategies can assist in adapting to the “rules of the game” while utilizing resources within the set contextual constraints.

The Impact

Image-guided ablation can provide effective local tumor control in selected patients with CLM. A randomized controlled trial suggested that radiofrequency ablation combined with systemic chemotherapy resulted in a survival benefit for patients with unresectable CLM, compared to systemic chemotherapy alone. For small tumors, ablation with adequate margins can be considered as an alternative to resection. The improvement of ablation technologies can allow the treatment of tumors close to major vascular structures or bile ducts, on which the applicability of thermal ablation modalities is challenging. Several factors affect the outcomes of ablation, including but not limited to tumor size, number, location, minimal ablation margin, RAS mutation status, prior hepatectomy, and extrahepatic disease. Further understanding of the impact of tumor biology and advanced imaging guidance on overall patient outcomes might help to tailor its application, and improve outcomes of image-guided ablation.

Purpose – This paper seeks to advance ongoing research in entrepreneurial perseverance. While the concept of perseverance is not new, few researchers paid attention to behavioural persistence in the entrepreneurial context. The purpose of this paper is to explore the emergence of new technology based firms (NTBF) by focusing on the role of nascent entrepreneurs’ social skills in the meeting the changes of entrepreneurial perseverance. Design/methodology/approach – In this paper the authors study the start-up phase of entrepreneurial process. The authors opted for a longitudinal case study approach in order to enhance the knowledge on entrepreneurs’ social skills and perseverance. For triangulation purpose the data were gathered using four different information sources. The use of Nvivo8 as the data analysis tool helped to impose a discipline and structure which facilitated the extraction of core insights. Findings – This paper contributes to the understanding of the entrepreneurial perseverance in the context of new venture creation. Particularly, reading the entrepreneurial process through the lens of the perseverance strategies model (Van Gelderen, 2012) provided a way to identify and then to assess the impact of the social skills on the overall entrepreneurial perseverance and their combined impact on the performance of NTBF creation process. In doing so, the authors identify the impact of entrepreneurs’ social skills to deal with a series of entrepreneurial problems such as scarcity of resources, uncertainty and ambiguity and consequently their impact on the likelihood of survival for new ventures. The issues that arose mostly reflected the inherent complexity of technology transfer processes, the university and entrepreneurs’ diverging cultures, and the very characteristics of the start-up phase of NTBFs. The findings reveal how social skills impact the entrepreneurial paths and probable outcomes. Research limitations/implications – This paper contributes to the understanding of the entrepreneurial perseverance in the context of NTBF creation. The findings reveal how social skills and perseverance impact the entrepreneurial paths and probable outcomes. Practical implications – The paper has implications for entrepreneurial support mechanisms such as technology business incubators in helping them to improve the efficacy and efficiency of their assistance to entrepreneurs through the development of their skill-sets and perseverance and providing enabling networking. In addition, the research has implications for entrepreneurship education and training. Indeed, there is an urgent need to design and implement courses and programs aiming at developing soft skills in entrepreneurship. Originality/value – In exploring networking and issues of perseverance for nascent entrepreneurs operating in new technology-based sectors, which the authors consider as an under searched area in entrepreneurial literature.

PurposeDespite the significance, university student start-ups and student entrepreneurship ecosystems (SEEs) have been subject to little research. This study aims to apply a qualitative emergent enquiry approach to explore best practice SEEs in Australia, complimented by narratives from leading scholars in higher education institutions with the aim of delineating the integrative components of SEEs.Design/methodology/approachAdopting the entrepreneurial ecosystem framework and aligned to the social cognitive theory, this paper explores the components and dynamics of SEEs, contributing to an understanding of how such components can better support the growth, sustainability and success of student start-ups. The authors extend entrepreneurship research on social construction using narrative research.FindingsThe findings provide guidelines for researchers, entrepreneurship scholars and educators, entrepreneurship students, policymakers and practitioners to enhance the impact and success of university student start-ups by adopting a student ecosystem approach.Research limitations/implicationsThe narratives represent a limited number of universities with an opportunity for further research to empirically measure the impact and outcomes of SEEs. The research is exploratory, inherently conceptual and emergent, providing an opportunity for validation of narrative frameworks in future studies.Practical implicationsThe findings may assist university managers to be more aware of their own subconscious preferences to student entrepreneurship and start-up initiatives, which may be useful in refining their impact and offerings regarding a quest toward the entrepreneurial university.Social implicationsFrom social perspectives, the alignment of the components of SEE has the ability to enhance and shift the entrepreneurial mindset of entrepreneurship students, notwithstanding enhancement of intentionality and self-efficacy.Originality/valueThis is the first study of SEEs in Australia, highlighting the importance of the integration of entrepreneurship education programs, entrepreneurship education ecosystems, the entrepreneurial university and specific start-up initiatives such as university accelerators. Furthermore, students may enhance their entrepreneurial mindset by actively engaging in such ecosystems.

The Impact

The societal benefits of addressing wasteful electricity use practices through behavioural interventions are now well-established. Surprisingly, in South Africa, where the economy is highly dependent on fossil fuel (coal) for electricity generation, this subject remains little studied and understood. The residential sector is a major electricity consumer, and high-income households, in particular, use a substantial proportion of total electricity with serious adverse impacts on grid stability and the environment, which can disproportionately affect the poor. Using a field-based experiment, this study examines the impact of behavioural interventions on household electricity savings and the determinants of success among high-income households in Johannesburg, South Africa. Over the intervention period, households exposed to a combination of electricity-saving information, frequent reminders and feedback on monthly electricity-saving performance showed mean electricity savings of about 1.5%, ranging from 2% to 4% of electricity, while households in the control group showed increased electricity consumption by approximately 11%. Out of all the demographic and personal value factors considered, age, achievement and benevolence promoted electricity savings, while household size, number of rooms, baseline electricity consumption and security inhibited savings. The findings empirically validate the impact of behavioural interventions on, and the positive influence of, personal values in promoting participation in electricity-saving actions within households.

Simultaneously improving the toughness and strength of B-microalloyed steel by adding microalloying elements (Nb, V, Ti) has been an extensively usedmethod for researchers. However, coarse Ti(C, N) particle will precipitate during solidification with inappropriate Ti content addition, resulting in poor impact toughness. The effect of the size, number density, and location of Ti(C, N) particle on the impact toughness of B-microalloyed steel with various Ti/N ratios was investigated. Coarse Ti(C, N) particles were investigated to act as the cleavage fracture initiation sites, by using scanning electron microscopy (SEM) analysis. When more coarse Ti(C, N) inclusions were located in ferrite instead of pearlite, the impact toughness of steel with ferrite–pearlite microstructure was lower. Meanwhile, when the size or the number density of Ti(C, N) inclusions was larger, the impact toughness was adversely affected. Normalizing treatment helps to improve the impact property of B-microalloyed steel, owing to the location of Ti(C, N) particles being partly changed from ferrite to pearlite. The formation mechanism of coarse Ti(C, N) particles was calculated by the thermodynamic software Factsage 7.1 and Thermo-Calc. The Ti(C, N) particles formed during the solidification of molten steel, and the N-rich Ti(C, N) phase precipitated first and, then, followed by the C-rich Ti(C, N) phase. Decreasing the Ti and N content is an effective way to inhibit the formation of coarse Ti(C, N) inclusions.
