Electrosurgical devices: are we closer to finding the ideal appliance? A critical review of current evidence for the use of electrosurgical devices in general surgery

Abstract Over the last decade, the use of electrosurgical devices has become commonplace across all surgical specialities. The current market is large enough to warrant a comparative review of each device. This has even more impetus given the budgetary constraints of NHS organisations. This review aims to compare the benefits and drawbacks of the most popular electrosurgical devices, whilst conducting a critical review of the literature. Structured searches using databases Medline and EMBASE were conducted. The search was restricted to English language papers only. Due to the abundance of literature, this review will focus on common general surgical procedures alone. Despite a plethora of available devices, individual preference still dictates use. Conventional diathermy may always have its place, but may see a decline in use if costs improve. Newer devices have shown comparable precision and added advantages.
DETERMINANTS OF GOVERNMENT AID TO KATRINA SURVIVORS: EVIDENCE FROM SURVEY DATA*

We analyze survey data from Mississippi coastal communities where Katrina made its final landfall. Logistic regressions indicate that government aid is helpful in dealing with one- to two-month economic disruption and long-term rebuilding but is less helpful with regard to short-term rebuilding and mitigating longer-term disruption. Our analysis (including a basic risk assessment) finds evidence that individuals receiving government aid and/or having a disability predisaster are likely to incur severe economic hardship postdisaster and that individuals with greater predisaster economic and/or social network capital seem to be less at risk. Our results underscore the importance of housing in the resumption of basic economic activity.
The Impact of Cash Flow Volatility on Discretionary Investment and the Costs of Debt and Equity Financing

We document that cash flow volatility is associated with lower levels of investment in capital expenditures, R&D, and advertising. Thus, firms do not turn to external capital markets to fully cover cash-flow short falls. Consistent with this conclusion, we document that the sensitivity of investment to cash flow volatility is greater for firms with higher costs of capital market access. In addition, cash flow and earnings volatility are associated with these higher costs. Thus, volatility not only increases the likelihood that a firm will need to access capital markets, it also increases the costs of doing so.
Housing and Family: An Introduction

This paper introduces the Housing Studies special issue ‘Housing and Family’. The issue consists of a collection of papers in which a number of connections between housing and family issues are highlighted. Three themes are addressed: the influence of the family of origin on housing characteristics and housing situations; the links between household events and housing events at the micro level of households; and homeownership as a context for parenthood at the macro level of countries. It is concluded that family is as much a context for understanding housing needs and residential outcomes as housing is a context for understanding family events.
Globalization, the welfare state and right-wing populism in Western Europe

We outline and test the argument that globalization contributes to the electoral success of the new far right in Western Europe. We also draw on the theory of embedded liberalism to advance and test the hypothesis that a comprehensive, generous and employment-orientated system of social protection lessens the economic insecurities attendant to internationalization and, in turn, weakens support for far-right parties. In empirical analysis of national elections in 16 European polities from 1981 to 1998, we find that the universal welfare state directly depresses the vote for radical right-wing populist parties and conditions the linkages between capital mobility, trade openness and foreign immigration on the one hand and electoral support for the new far right on the other. In conclusion, we consider our findings’ implications for understanding the domestic political effects of globalization and sources of right-wing populism as well as for policy reforms that promote political economic stability in an era of international integration.
Arterial rupture in classic Ehlers–Danlos syndrome with COL5A1 mutation

The vascular type of Ehlers–Danlos syndrome (EDS IV) is associated with a high risk of life‐threatening medical complications, including ruptures of large arteries, the intestine, and the uterus during pregnancy. An arterial rupture occurring in an individual with EDS is regarded as almost diagnostic of EDS IV, which is caused by heterozygous mutations in COL3A1. Here however, we report on a man with skin lesions typical of EDS, easy bruising and recurrent inguinal hernias who had a spontaneous rupture of the left common iliac artery at the age of 42 years but in whom we detected no COL3A1 mutation. As he clinically fulfilled the diagnostic criteria for classic EDS (EDS I), we sequenced the major EDS I gene COL5A1 and identified a heterozygous de novo nonsense mutation, c.3184C>T (p.R1062X). As, to the best of our knowledge, this is the first report of a patient with COL5A1 mutation‐positive classic EDS and rupture of a large artery, we suggest that arterial rupture might be a rare complication of classic EDS. This finding has potential implications for genetic counseling and molecular genetic testing in Ehlers–Danlos syndrome. © 2010 Wiley‐Liss, Inc.
Does Household Consumption Behave As A Martingale? A Test For Rural South India

AbstractThe hypothesis that consumption evolves over time as a martingale process is tested on household panel data for three villages in south India. A novel feature of the methodology is that it gives consistent estimates of dynamic effects in short panels. The estimated coefficients of lagged consumption are generally smaller than unity and a number of the lagged income and wealth variables are statistically significant. The results are inconsistent with the proposition that consumption equals permanent income. This is also true when the data are disaggregated by household wealth.
Higher-Order Systematic Comoments and Asset Pricing: New Evidence

We provide evidence supporting Rubinstein's (1973) model that if returns are not normal, measuring risk requires more than just measuring covariance. Higher-order systematic comoments should be important to risk-averse investors who are concerned about the extreme outcomes of their investments. Our paper shows that the Fama-French factors [SMB (return on small stocks less the return on big stocks), HML (return on high book-to-market stocks less the return on low book-to-market stocks)] as well as the momentum and market liquidity factors can be explained by the higher-order systematic comoments, and it lends support to the traditional covariance risk-based theory without having to resort to behavior assumptions.
Intergenerational Housing Support Between Retired Old Parents and their Children in Urban China

Intergenerational support between parents and children in Chinese cities has been dramatically affected by recent social changes. This paper investigates the changing pattern of intergenerational housing support between retired old parents and their children, and the legacy of public housing in shaping this pattern. By initially establishing an up-to-date picture of intergenerational housing support between retired old parents and their children, it seeks to determine how this support depends on whether parents have previously been allocated public housing and, if so, on whether they have disposed of it or have continued to occupy it. A survey with 1000 retired old people from Tianjin in 2009 is used for the analysis. A support flow model is used to go beyond studying housing support per se, and to study the flow of intergenerational support in both directions and in different forms.
The entrepreneur’s perception on information technology innovation adoption: An empirical analysis of the role of precipitating events on usage behavior

The Unified Theory of Acceptance and Use of Technology (UTAUT) is a fairly developed model. Like any model, however, it has limitations, mainly in its relationship between the intention and use behavior. This paper will attempt to explain the influence of external factors that potentially inhibit or facilitate the performance of a behavior, as well as effects of the propensity to act on determinants toward intention for action. Based on the UTAUT limitations, we added precipitating events to measure the effect of external factors (such as government policy, financial crisis, and new market) on IT innovation and adoption and examined the effect of the propensity to act as a moderator on the relationship between the determinants intention and usage behavior, and hypothesized that in the condition where propensity to act is high, taking action will be more predictable. The data used to test the hypotheses were collected from a varied spectrum of Malaysian industries and entrepreneurs (SMEs owners). A total of 1,000 businesses were identified and questionnaires were distributed in person by the authors, and 420 completed questionnaires were returned. The research model used structural equation modeling techniques, and the current study validated the UTAUT model in the entrepreneurship context while showing that performance expectancy, effort expectancy and social influence were all positive influences on behavior intention. Facilitating conditions and behavior intention are important variables for determining the origins of behavior for IT innovation. The results of the study confirmed the moderating effects of propensity to act and precipitating factors in the model. Results indicated that precipitating events can capture the influence of external factors on the behavioural intention to take action, improve the model, and fill the intention–behaviour gap. The current study shows the significant effect of life events on the behavioural intention to take action.
Endogenous vs. Semi-endogenous Growth in a Two-R&D-Sector Model

This paper contributes to the endogenous versus semi-endogenous growth debate by establishing that semi-endogenous growth is more general than endogenous growth in a two-R&D-sector growth model. It is demonstrated that endogenous growth requires two "knife-edge" conditions of parameters. This finding (i) is in sharp contrast to recent two-R&D-sector models that show that long-run growth is endogenous, and (ii) resurrects the policy conclusion of semi-endogenous growth that government policy is not effective in raising the underlying growth rate of an economy. The driving force of these results is knowledge spillovers between two R&D activities, which are largely neglected in existing studies.
A dynamic limit order market with fast and slow traders

We study the role of high-frequency trading in a dynamic limit order market. Being fast is valuable because it enables traders to revise outstanding limit orders upon news arrivals when interacting with slow market participants. On the one hand, the existence of fast traders can help to reduce the ine¢ ciency that is rooted in the risk of being "picked o¤" after unfavourable price movements and therefore allows more gains from trade to be realized. On the other hand, slow traders face a relative loss in bargaining power which leads them to strategically submit limit orders with a lower execution probability, thereby reducing trade. Due to this negative externality, the equilibrium level of investment is always welfare-reducing. The model generates
Identifying Lynch Syndrome in Patients With Ovarian Carcinoma: The Significance of Tumor Subtype

Up to 15% of ovarian cancers are etiologically linked with hereditary susceptibility. Within this group, germline mutations in mismatch repair (MMR) genes, known otherwise as Lynch syndrome (LS), account for the majority of cases that are not associated with mutations in BRCA1 or BRCA2. Clinical schemas specific for gynecologic cancers have been developed to identify patients with LS; however, many of the recommendations are poorly defined. Few case series of germline-confirmed LS-associated ovarian cancers have been reported, limited by small sample size and often lacking central pathology review. Much insight has been gained from studies of unselected cohorts, using immunohistochemical assessment of MMR protein expression or microsatellite instability analysis. In spite of contradictory results, likely reflective of differences in study design, sample size and methodology, a recurring observation is the overrepresentation of “endometriosis-associated tumors,” namely, endometrioid and clear cell subtypes, in the group of ovarian tumors with MMR deficiency. In this review, we summarize the clinical and histomorphologic features of LS-associated/MMR-deficient ovarian epithelial cancers and recommend that reflex testing be performed on the basis of tumor subtype.
Advertising Spending Efficiency Among Top U.S. Advertisers from 1985 to 2012: Overspending or Smart Managing?

The current study tests two competing predictions of long-term adspend efficiency: the “overspending perspective” predicts continued high inefficiency, while the “smart manager perspective” predicts improved efficiency. Longitudinal analysis of efficiency among top 100 U.S. advertisers from 1985 to 2012 using data envelopment analysis reveals that inefficiency has increased over time. Approximately 61% of top advertisers are inefficiently using their ad dollars and are overspending by an average of 34%. Findings also indicate that the Internet, a medium highly praised and utilized for the amount and depth of consumer data it generates, has not impacted overall efficiency in any meaningful way.
Genetic structure of the whitefly Bemisia tabaci populations in Colombia following a recent invasion

The whitefly Bemisia tabaci (Gennadius) is one of the most important pests causing economic losses in a variety of cropping systems around the world. This species was recently found in a coastal region of Colombia and has now spread inland. To investigate this invasive process, the genetic structure of B. tabaci was examined in 8 sampling locations from 2 infested regions (coastal, inland) using 9 microsatellite markers and the mitochondrial COI gene. The mitochondrial analysis indicated that only the invasive species of the B. tabaci complex Middle East–Asia Minor 1 (MEAM 1 known previously as biotype B) was present. The microsatellite data pointed to genetic differences among the regions and no isolation by distance within regions. The coastal region in the Caribbean appears to have been the initial point of invasion, while the inland region in the Southwest showed genetic variation among populations most likely reflecting founder events and ongoing changes associated with climatic and topographical heterogeneity. These findings have implications for tracking and managing B. tabaci.
Factors influencing the adoption of online recruitment

Purpose – The internet is initially hailed as the future of recruitment and is expected to replace other media as the preferred recruitment method, but the adoption of online recruitment has not been as comprehensively predicted. In addition, empirical research regarding online recruitment from an organisational perspective is sparse. This paper aims to examine the reasons behind an organisation's decision to use online recruitment, and reports on the development of a model of the factors affecting the adoption of this recruitment method.Design/methodology/approach – The paper uses in‐depth interviews and a survey of human resource (HR) managers with recruitment responsibility. The factors that affect the adoption of online recruitment are explored, and related to Rogers's diffusion of innovation theory (DIT) and Ajzen's theory of planned behaviour (TPB). Findings – Factors related to the adoption of corporate web sites and commercial jobs boards are found to be different, with positive beliefs/relative ad.
THE ROLE OF HUMAN AND SOCIAL CAPITAL AND ENTREPRENEURIAL ORIENTATION FOR SMALL BUSINESS PERFORMANCE IN A TRANSITIONAL ECONOMY

We develop a model of small business performance in transitional economies in which owners' human and social capital are expected to be directly and positively related to the firm's entrepreneurial orientation, and all three are hypothesised to have a positive impact on performance. In transitional economies, these factors are particularly salient because of the scarcity of resources and the lack of entrepreneurial tradition and adequate institutional infrastructure. The model is tested with structural equations analysis of data from 160 owners of small businesses in Bulgaria. We find that social capital is related to entrepreneurial orientation, and both are positively associated with business performance. This means that social capital is an important initial resource endowment in transforming economies, and small business owners need to establish and develop connections with partners, suppliers, customers, and institutions. Also, they should seek to identify opportunities and develop proactive and innovative strategies.
A climate change vulnerability assessment methodology for coastal tourism

Coastal and marine environments are among the most popular areas for outdoor recreation and tourism. Coastal areas have also been identified as the most vulnerable to climate change, for example as a result of extreme events and sea-level rise. It will be increasingly important for coastal tourism destination managers to understand their vulnerability to climatic changes and to devise appropriate adaptation. This paper presents a five-step vulnerability assessment methodology for tourism in coastal areas. The five steps include (1) system analysis, (2) identification of activity and hazard sub-systems, (3) vulnerability assessments for the different sub-systems at risk, (4) integration for the destination as a whole and scenario analysis and (5) communication. The framework is illustrated by an example of how it might be applied to Fiji. The paper concludes that a consistent methodology, like the one proposed, will facilitate vulnerability assessments in a range of coastal destinations, allow comparison to be made of vulnerabilities across different situations, provide a basis for more research into specific adaptation measures and assist destinations to develop a more sustainable tourism industry.
Lymphangiomas in children: percutaneous sclerotherapy with an alcoholic solution of zein.

PURPOSE To determine the efficacy of percutaneous sclerotherapy with an alcoholic solution of zein in lymphangiomas in pediatric patients. MATERIALS AND METHODS Fourteen patients with macrocystic and mixed lymphangiomas were treated with use of Ethibloc as a sclerosing agent. The procedure was performed with ultrasonographic and/or fluoroscopic guidance. Follow-up clinical and sequential computed tomographic examinations were performed to evaluate regression of the lesion. RESULTS Regression was excellent in nine (64%) of the 14 lesions: Regression was complete in four lymphangiomas and was to less than 5% of the initial volume in five. Satisfactory results were obtained in the remaining five (36%) of 14 lesions. The most frequent complication was leakage of Ethibloc without important sequelae in 10 of the 14 lymphangiomas. CONCLUSION Percutaneous sclerotherapy with Ethibloc was a safe and effective procedure in the treatment of macrocystic and mixed lymphangiomas.
The Role of Customer Engagement in Building Consumer Loyalty to Tourism Brands

Customer engagement has recently emerged in both academic literature and practitioner discussions as a brand loyalty predictor that may be superior to other traditional loyalty antecedents. However, empirical inquiry on customer engagement is relatively scarce. As tourism and hospitality firms have widely adopted customer engagement strategies for managing customer–brand relationships, further understanding of this concept is essential. Using structural equation modeling, this study investigates the linkages of customer engagement with traditional antecedents of brand loyalty. Results based on 496 hotel and airline customers suggest that customer engagement enhances customers’ service brand evaluation, brand trust, and brand loyalty. The results show that service brand loyalty can be strengthened not only through the service consumption experience but also through customer engagement beyond the service encounter. This study contributes to the literature by providing an empirical evaluation of the relationships between customer engagement and key brand loyalty development factors.
Environmental management and its impact on the operations function

Recently, corporations have been confronted with a number of global environmental challenges such as global warming, acid rain, depletion of natural resources, waste management, green consumerism and pollution prevention. There is growing pressure to deliver products and services which are environmentally compatible. A number of corporations such as Du Pont, 3M, AT&T, Xerox and Procter & Gamble are, therefore, integrating various environmental policies and programmes into their operations strategy and specific decisions concerning operations such as product design/planning, process technology selection, and quality management. Introduces the concepts of environmental management (EM) and argues that firms which do not recognize the implications of environmental problems on the operations function will not succeed in the competitive market. Various environmental management practices (such as implementing aggressive pollution‐prevention programmes, initiating environment‐related performance measures and deve.
Consumption values and consumer environmental concern regarding green products

This study applied the partial least squares (PLS) approach using the SmartPLS computer program to examine the impact of consumption values (i.e. functional value, social value, emotional value, conditional value and epistemic value) on consumer environmental concern about green products. The views of individuals from the general public in the Federal Territory of Labuan, Malaysia, were gathered through the use of a self-administered questionnaire. This was completed by 200 respondents who adopted a green lifestyle and were committed to buying green products such as organic vegetables at least once a week. The empirical results obtained via the PLS approach revealed that social value had the most significant effect on consumer environmental concerns regarding green products. This finding showed the significant influence of peer opinion on individuals’ acceptance of green products and their impressions when purchasing such products. The next important factor is the epistemic value related to the purchasing.
