Abstract Purpose Due to the ongoing discussion of the usefulness of dissection on human bodies in medical curricula, we investigated the influence of anatomical knowledge collected in the dissection course and requested for modules of visceral surgery. Methods Students attending the dissection course of topographic anatomy had to answer a questionnaire of 22 questions with focus on anatomical knowledge required for visceral surgical modules. Failure was defined as 13 or fewer correct answers, success categorized as high, good or moderate. The same questionnaire was handed out to 245 students prior to the module on visceral surgery. Students provided information on which regions they had dissected during the course or prior to the module. The results were compared to the result of a written Multiple Choice Question (MCQ) exam of the module visceral surgery (n = 160 students) with an unannounced primary focus on anatomy. Results Students who dissected the truncal regions of the human body succeeded in answering the questionnaire with high success. Students dissecting regions of the Head/Neck or Limbs had a high failure rate, and none of them reached the “high” success level. In the MCQ exam, students dissecting truncal regions had a high success rate, while those who had not dissected or who dissected the Head/Neck or Limbs had a high failure rate. Conclusion Dissections support and improve the required knowledge for surgical modules. For the visceral surgical module, students dissecting the region prior to the module greatly benefited. Therefore, entire human body dissection assumes to be preferable.

What barriers obstruct the success of knowledge management programs? This paper has integrated studies on the barriers to knowledge management (KM) into a theoretical framework. Based on this framework, five cases documenting failed KM initiatives were analysed. The analysis gives a clear picture about why certain KM projects fail. The high failure rate of KM can be explained by the supply-IT based approach many organisations adopt when it comes to their KM programs. To increase the success rate of KM projects, companies should go beyond the one-dimensional thinking, e.g. technology, and adopt an approach where all the ingredients of KM operate in a synchronised way.

The aim of this paper is to explore innovative behaviour of Indian Micro Small and Medium Enterprises. It is interesting to study innovative behaviour of microsmau and medium enterprises (MSMEs) since they try to innovate while surrounded by many barriers. They also face high failure rate in doing so. This failure is due to presence of barriers that MSMEs fail to manage. But it has been observed that many MSMEs are now awakening to their potential and becoming innovative. They tend to respond to environmental factors in an innovative way, either by cutting cost or changing ways of management. This innovative way defines their innovative behaviour. The innovative behaviour of MSMEs is studied through three variables, i.e., size, age and barriers faced by them. The result shows that size does influence innovation activities undertaken by MSMEs and statistically, there is no correlation between age and innovative behaviour. Their innovative behaviour is affected by barriers like shortage of technical skilled manpower, technology and shortage of funds or complex funding procedure. The paper is concluded by summarising the key findings, discussing implications, limitations and further scope of study.

ObjectiveRapid implementation of home sleep studies during the first UK COVID-19 ‘lockdown’—completion rates, family feedback and factors that predict success.DesignWe included all patients who had a sleep study conducted at home instead of as inpatient from 30 March 2020 to 30 June 2020. Studies with less than 4 hours of data for analysis were defined ‘unsuccessful’.Results137 patients were included. 96 underwent home respiratory polygraphy (HRP), median age 5.5 years. 41 had oxycapnography (O2/CO2), median age 5 years. 56% HRP and 83% O2/CO2 were successful. A diagnosis of autism predicted a lower success rate (29%) as did age under 5 years.ConclusionSwitching studies rapidly from an inpatient to a home environment is possible, but there are several challenges that include a higher failure rate in younger children and those with neurodevelopmental disorders.

AbstractWe present a fast and reliable reconstruction of proofs generated by the SMT solver veriT in Isabelle. The fine-grained proof format makes the reconstruction simple and efficient. For typical proof steps, such as arithmetic reasoning and skolemization, our reconstruction can avoid expensive search. By skipping proof steps that are irrelevant for Isabelle, the performance of proof checking is improved. Our method increases the success rate of Sledgehammer by halving the failure rate and reduces the checking time by 13%. We provide a detailed evaluation of the reconstruction time for each rule. The runtime is influenced by both simple rules that appear very often and common complex rules.

In todays global environment, strategic alliances represent an important source of growth and competitive advantage; they allow firms to access new and critical resources and capabilities, to improve competitive position and rapidly to enter a new market In spite of the strategic importance of the alliances, they still exhibit a high failure rate; previous researches show that the half of the alliance formed end up as failure. The low success rate testifies firms difficulties in managing their alliance relationships and in ensuring enough success from them. In global markets, firms exhibit heterogeneity in terms of the overall alliance success; some firms achieve success from their alliance and others fail. Although most companies have realized the importance of strategic alliances, only few of them have developed the needed capabilities to manage them with success. In recent years, empirical studies found that firms with greater alliance success are those ones with superior management capabilities, termed in literature as alliance capabilities. This study is based on the assumption that the heterogeneity in alliance success rate is due to heterogeneity in firms level of management capabilities. Eli Lilly & Companys success in strategic alliances represents a clear example of company that understood the importance of developing an institutionalized approach of alliance management that improves the likelihood of alliance success.

Background Video laryngoscopy is an effective tool in the management of difficult pediatric airway. However, evidence to guide the choice of the most appropriate video laryngoscope (VL) for airway management in pediatric patients with Pierre Robin syndrome (PRS) is insufficient. Therefore, the aim of this study was to compare the efficacy of the Glidescope® Core™ with a hyperangulated blade, the C-MAC® with a nonangulated Miller blade (C-MAC® Miller) and a conventional Miller laryngoscope when used by anesthetists with limited and extensive experience in simulated Pierre Robin sequence. Methods Forty-three anesthetists with limited experience and forty-three anesthetists with extensive experience participated in our randomized crossover manikin trial. Each performed endotracheal intubation with the Glidescope® Core™ with a hyperangulated blade, the C-MAC® with a Miller blade and the conventional Miller laryngoscope. “Time to intubate” was the primary endpoint. Secondary endpoints were “time to vocal cords”, “time to ventilate”, overall success rate, number of intubation attempts and optimization maneuvers, Cormack-Lehane score, severity of dental trauma and subjective impressions. Results Both hyperangulated and nonangulated VLs provided superior intubation conditions. The Glidescope® Core™ enabled the best glottic view, caused the least dental trauma and significantly decreased the “time to vocal cords”. However, the failure rate of intubation was 14% with the Glidescope® Core™, 4.7% with the Miller laryngoscope and only 2.3% with the C-MAC® Miller when used by anesthetists with extensive previous experience. In addition, the “time to intubate”, the “time to ventilate” and the number of optimization maneuvers were significantly increased using the Glidescope® Core™. In the hands of anesthetists with limited previous experience, the failure rate was 11.6% with the Glidescope® Core™ and 7% with the Miller laryngoscope. Using the C-MAC® Miller, the overall success rate increased to 100%. No differences in the “time to intubate” or “time to ventilate” were observed. Conclusions The nonangulated C-MAC® Miller facilitated correct placement of the endotracheal tube and showed the highest overall success rate. Our results therefore suggest that the C-MAC® Miller could be beneficial and may contribute to increased safety in the airway management of infants with PRS when used by anesthetists with limited and extensive experience.
