The role of guanxi networks in the performance of women-led firms in China

This exploratory paper examines how knowledge acquired via guanxi (networks and connections) have enabled women-led firms in China to overcome a number of significant barriers and challenges in order to start and grow a successful business. We draw upon two case studies, in order to illustrate how they have utilized guanxi as a means of overcoming these barriers. We investigate the way in which guanxi facilitates the business owner in engaging in a process of entrepreneurial learning (Harrison and Leitch 2005; Politis, 2008) – and making connections and contacts – by which she is able to improve the firm’s performance. Further research is necessary to build upon a small number of studies that have already cleared the ground in terms of guanxi. More reliable and country-wide, but disaggregated, statistics on small businesses would be a welcome start, including information on their owner-manager’s or owner-managers’ gender

"Enter the dragoness": Firm growth, finance, guanxi, and gender in China

Purpose: The purpose of this exploratory paper is to theorise and examine gender differences in the impact of financial capital on Chinese firms' growth, and investigate the role of guanxi (connections and networks) in the process of obtaining finance. Design/methodology/approach: A structured questionnaire is used to collect comprehensive financial data from 18 women to 69 men, which is analysed empirically. Findings: Women appear to be no more disadvantaged from obtaining finance than men in China and in some respects appear to be in a better position. Both women- and men-led firms are significantly stronger in relation to having access to enough finance to grow than at the start-up phase. A majority of participants in this study used guanxi to access finance. Furthermore, the paper finds that guanxi is used equally by men and women, and that guanxi-sourced finance comprised a significant proportion of the overall capital obtained. Research limitations/implications: One major limitation of the study is that, of the 87 questionnaires returned, 21 per cent are women and 79 per cent are men and, although the findings are not representative or generalisable, the results do suggest a number of possible avenues for future research. Originality/value: The paper has illuminated the under-explored area of the financing of growth in women-led firms in China. This research agenda is particularly important because small- and medium-sized enterprise finance in China is a key need-to-know area, there is a paucity of specific research on financing women entrepreneurs in China and of the phenomenal rise of women's entrepreneurship in China. © Emerald Group Publishing Limited

Core Services in the Architecture of the National Digital Library for Science Education (NSDL)

We describe the core components of the architecture for the (NSDL) National Science, Mathematics, Engineering, and Technology Education Digital Library. Over time the NSDL will include heterogeneous users, content, and services. To accommodate this, a design for a technical and organization infrastructure has been formulated based on the notion of a spectrum of interoperability. This paper describes the first phase of the interoperability infrastructure including the metadata repository, search and discovery services, rights management services, and user interface portal facilities

Angular dependence of the radiation power of a Josephson STAR-emitter

We calculate the angular dependence of the power of stimulated terahertz amplified radiation (STAR) emitted from a $dc$ voltage applied across a stack of intrinsic Josephson junctions. During coherent emission, we assume a spatially uniform $ac$ Josephson current density in the stack acts as a surface electric current density antenna source, and the cavity features of the stack are contained in a magnetic surface current density source. A superconducting substrate acts as a perfect magnetic conductor with $H_{||,ac}=0$ on its surface. The combined results agree very well with recent experimental observations. Existing Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ crystals atop perfect electric conductors could have Josephson STAR-emitter power in excess of 5 mW, acceptable for many device applications.Comment: 3 pages 3 figure

Investigation into the cause of spontaneous emulsification of a free steel droplet : validation of the chemical exchange pathway

Small Fe-based droplets have been heated to a molten phase suspended within a slag medium to replicate a partial environment within the basic oxygen furnace (BOF). The confocal scanning laser microscope (CSLM) has been used as a heating platform to interrogate the effect of impurities and their transfer across the metal/slag interface, on the emulsification of the droplet into the slag medium. The samples were then examined through X-ray computer tomography (XCT) giving the mapping of emulsion dispersion in 3D space, calculating the changing of interfacial area between the two materials, and changes of material volume due to material transfer between metal and slag. Null experiments to rule out thermal gradients being the cause of emulsification have been conducted as well as replication of the previously reported study by Assis et al.[1] which has given insights into the mechanism of emulsification. Finally chemical analysis was conducted to discover the transfer of oxygen to be the cause of emulsification, leading to a new study of a system with undergoing oxygen equilibration

Contemporary Surgery for Obstructive Sleep Apnea Syndrome

Surgical treatment of obstructive sleep apnea syndrome (OSAS) has been available in some form for greater than three decades. Early management for airway obstruction during sleep relied on tracheotomy which although life saving was not well accepted by patients. In the early eighties two new forms of treatment for OSAS were developed. Surgically a technique described as a uvulopalatopharyngoplasty (UPPP) was used to treat the retropalatal region for snoring and sleep apnea. Concurrently sleep medicine developed a nasal continuous positive airway pressure (CPAP) device to manage nocturnal airway obstruction. Both of these measures were used to expand and stabilize the pharyngeal airway space during sleep. The goal for each technique was to limit or alleviate OSAS. Almost 30 yr later these two treatment modalities continue to be the mainstay of contemporary treatment. As expected, CPAP device technology improved over time along with durable goods. Surgery followed suit and additional techniques were developed to treat soft and bony structures of the entire upper airway (nose, palate and tongue base). This review will only focus on the contemporary surgical methods that have demonstrated relatively consistent positive clinical outcomes. Not all surgical and medical treatment modalities are successful or even partially successful for every patient. Advances in the treatment of OSAS are hindered by the fact that the primary etiology is still unknown. However, both medicine and surgery continue to improve diagnostic and treatment methods. Methods of diagnosis as well as treatment regimens should always include both medical and surgical collaborations so the health and quality of life of our patients can best be served

Early Last Interglacial ocean warming drove substantial ice mass loss from Antarctica

The future response of the Antarctic ice sheet to rising temperatures remains highly uncertain. A useful period for assessing the sensitivity of Antarctica to warming is the Last Interglacial (LIG) (129 to 116 ky), which experienced warmer polar temperatures and higher global mean sea level (GMSL) (+6 to 9 m) relative to present day. LIG sea level cannot be fully explained by Greenland Ice Sheet melt (∼2 m), ocean thermal expansion, and melting mountain glaciers (∼1 m), suggesting substantial Antarctic mass loss was initiated by warming of Southern Ocean waters, resulting from a weakening Atlantic meridional overturning circulation in response to North Atlantic surface freshening. Here, we report a blue-ice record of ice sheet and environmental change from the Weddell Sea Embayment at the periphery of the marine-based West Antarctic Ice Sheet (WAIS), which is underlain by major methane hydrate reserves. Constrained by a widespread volcanic horizon and supported by ancient microbial DNA analyses, we provide evidence for substantial mass loss across the Weddell Sea embayment during the LIG, most likely driven by ocean warming and associated with destabilization of subglacial hydrates. Ice sheet modeling supports this interpretation and suggests that millennial-scale warming of the Southern Ocean could have triggered a multimeter rise in global sea levels. Our data indicate that Antarctica is highly vulnerable to projected increases in ocean temperatures and may drive ice–climate feedbacks that further amplify warming
