Authors: Lee Jae Woo , Hong Kyeongsoo , Koo Jae-Rim , Park Jang-Ho
Published: December 2019

We present the first high-resolution spectra for the eclipsing binary V404 Lyr showing γ Dor pulsations, which we use to study its absolute properties. By fitting models to the disentangling spectrum of the primary star, we found that it has an effective temperature of T
eff,1 = 7330 ± 150 K and a rotational velocity of v
1 sin i = 148 ± 18 km s−1. The simultaneous analysis of our double-lined radial velocities and the pulsation-subtracted Kepler data gives us accurate stellar and system parameters of V404 Lyr. The masses, radii, and luminosities are M

By applying a multiple frequency analysis to the eclipse-subtracted light residuals, we detected 45 frequencies with signal-to-noise amplitude ratios larger than 4.0. Identified as independent pulsation modes, seven frequencies (f

Published: December 2019

A few hours after its encounter with Pluto, the Alice UV instrument on the New Horizons spacecraft observed the simultaneous stellar occultation and appulse of two UV-bright stars, HD 43153 and HD 42545, respectively. As during the solar occultation that occurred immediately prior, the transmission of starlight through Pluto’s atmosphere was sensitive to absorption by N2, CH4, C2H6, C2H2, C2H4, and haze. The line of sight to each star passed over different areas of Pluto from those probed by the solar occultation, providing insight into the degree of spatial and diurnal variability of atmospheric composition on Pluto. In this work, we report the profile of CH4 derived from both the stellar occultation and appulse observation, as well as the profiles of C2H6, C2H2, C2H4, and haze for the stellar occultation only. We compare these profiles to the solar occultation results and discuss implications for atmospheric variability on Pluto.
Clustering of Local Group Distances: Publication Bias or Correlated Measurements? VI. Extending to Virgo Cluster Distances
Authors: de Grijs Richard , Bono Giuseppe
Published: December 2019

We have established an internally consistent Local Group distance framework, using the Galactic Center, the Large Magellanic Cloud, and Messier 31 (M31) as important stepping stones. At greater distances, few distance benchmarks are available. As a consequence, M87 and/or Virgo cluster distances are often invoked as the next rung on the ladder to more distant objects such as the Fornax and Coma clusters. Therefore, we extensively mined the published literature for independently derived distance estimates to either M87 or the center of the Virgo cluster. Based on our newly compiled, comprehensive database of 213 such distances, published between 1929 and 2017 July, we recommend an outward extension to our distance framework,

mag (D = 16.07 ± 1.03 Mpc; where the uncertainty represents the Gaussian σ of the distribution), based on a subset of recent (post-1990) M87/Virgo cluster distance measurements. The most stable distance tracers employed here were derived from analysis of both primary and secondary distance indicators. Among the former, we preferentially rely on Cepheid period–luminosity relations and red-giant-branch terminal magnitudes; our preferred secondary distance tracers are surface brightness fluctuations. Our updated distance modulus to M87 implies a slightly reduced black hole mass of (5.9 ± 0.6) × 109

Published: December 2019

Objective. To compare frequency of echocardiographic changes in patients with chronic obstructive pulmonary disease (COPD) and non-COPD controls and to assess their relation to the level of airflow limitation.
Methods. Study population included 120 subjects divided in two groups. Group 1 included 60 patients with COPD (52 male and 8 female, aged 40 to 80 years) initially diagnosed according to the actual recommendations. Group 2 included 60 subjects in whom COPD was excluded serving as a control. The study protocol consisted of completion of a questionnaire , pulmonary evaluation (dyspnea severity assessment, baseline and post-bronchodilator spirometry, gas analyses, and chest X-ray) and two dimensional (2D) Doppler echocardiography.
Results. We found significantly higher mean right ventricle end-diastolic dimension (RVEDd) in COPD patients as compared to its dimension in controls (28.0 Â± 4.8 vs. 24.4 Â± 4.3; P = 0.0000). Pulmonary hypertension (PH) was more frequent in COPD patients than in controls (28.0 Â± 4.8 vs. 24.4 Â± 4.3; P = 0.0000) showing linear relationship with severity of airflow limitation. The mean value of left ventricular ejection fraction (LVEF%) was significantly lower in COPD patients than its mean value in controls (57.4 Â± 6.9% vs. 64.8 Â± 2.7; P = 0.0000) with no correlation with severity of airflow limitation.      
Conclusion. Frequency of echocardiographic changes in COPD patients was significantly higher as compared to their frequency in controls in the most cases being significantly associated with severity of airflow limitation. Echocardiography enables early, noninvasive, and accurate diagnosis of cardiac changes in COPD patients giving time for early intervention.

Authors: Deconto Diomar Caríssimo Selli , Cavalcanti Cláudio José de Holanda , Ostermann Fernanda
Published: December 2019

Este trabalho tem por objetivo estudar o processo de construção de compreensões sobre ciência, no âmbito de discussões sobre a perspectiva CTS, de estudantes de um curso de Licenciatura em Física. Parte-se do conceito de racionalidade científica, que representa uma dimensão da natureza  da ciência e permite vinculá-la ao contexto das relações CTS, e assume-se como referencial teórico-metodológico as ideias do pensamento bakhtiniano, uma vez que o discurso instaurado entre os estudantes ao longo de uma disciplina que serviu de contexto de investigação será o foco da análise. A análise bakhtiniana foi articulada com uma Análise de Correspondência Simples, em uma perspectiva de método misto. Pela análise desenvolvida foi possível identificar avanços na compreensão sobre ciência dos estudantes com relação ao início da disciplina e, principalmente, compreender aspectos que moldam as concepções destes estudantes, como a influência dos professores formadores e do manual didático.

Percebemos que ambos são adequados à organização de ideias, além de permitir compreender de que forma a Matemática e a Física são percebidas pelos estudantes.
The Use of an Injectable Bone Graft Substitute in Tibial Metaphyseal Fractures
Authors: Watson J Tracy
Published: December 2019

Abstract

Eight consecutive patients with severely comminuted proximal or distal tibial metaphyseal fractures were surgically treated with a novel injectable, in situ hardening calcium sulfate material to provide temporary intraoperative structural support until instrumentation was appropriately placed. The calcium sulfate bone substitute was also used as a bone void filler to provide an osteoinductive environment following stabilization. Bone regrowth was observed in all patients and, in seven of the eight patients, 90%-100% bone formation was observed within 3 months. The bone substitute had almost completely resorbed by 3 months in all patients. One patient with extensive initial bone loss required a second bone graft. Although the patient sample size was small, the success rate of treating severely comminuted fractures was significantly better than in reports using only internal fixation. Injectable bone substitute provides a viable alternative for minimally invasive surgery to repair metaphyseal fractures.
Evaluation of Four Microkeratome Models: Quality and Reproducibility of Cut Edge and Cut Surface as Determined by Scanning Electron Microscopy
Authors: Hammer Thomas , Hanschke Renate , Wörner Isabelle , Wilhelm Frank W
Published: December 2019

ABSTRACT

PURPOSE: To compare the quality and reproducibility of cuts produced by four automatic microkeratomes: Amadeus, Hansatome, Summit-Krumeich-Barraquer (SKBM), and Supratome. For the adjustable models (Amadeus and SKBM), the effects of oscillation frequency and blade feed rate were determined.

METHODS: Eight cuts (flap thickness 160 to 180 /im) were made with each microkeratome at each parameter setting and examined using a scanning electron microscope. Quality of the cut surface was scored for each flap according to four criteria, and results were averaged to give a maximum possible score of 64. Quality of the cut edges was scored from 1 (blurred indistinct edge) to 3 (sharp and clearly visible edge).

RESULTS: The four microkeratomes performed similarly on overall quality of the cut surface (range: 78% to 88% of theoretical maximum). The Hansatome scored highest (88%), followed by SKBM (86%; 1.0 mm/s blade feed and 7000 rpm oscillation), Amadeus (84%; 2.5 mm/s, 8000 rpm), Supratome (84%; 16.67s, 12,500 rpm), Amadeus (81%; 3.0 mm/s and 13,000 rpm), and SKBM (78%; 1.5 mm/s, 14,000 rpm). Performance differences were clearer for cut edge quality. The Amadeus produced cuts of the highest quality in 62.5% of cases (at both settings), compared with only 12.5% of cases with the Hansatome, 25% of cases with the Supratome and SKMB (1.0 mm/s, 7000 rpm), and in no cases with the SKBM at 1.5 mm/s and 14,000 rpm.

CONCLUSIONS: Overall, high frequency with low blade feed rate is desirable for reproducible sharp edges and cut area quality. However, at very high frequencies (eg, 14,000 rpm with the SKBM) tissue is displaced, producing an uneven cut area. Oscillation/feed quotients of 2000 to 4000 (rpm/mmxs) are a good compromise. Sharp edges are believed to reduce the risk of corneal erosion, introduction of epithelial cells into the interfacial region, and scarring during wound healing. [J Refract Surg. 2005;21:454-462.]

Authors: Lin Jane-Ming , Tsai Yi-Yu
Published: December 2019

ABSTRACT

PURPOSE: To report a case of retinal phlebitis with cystoid macular edema in both eyes 8 weeks after LASIK.

METHODS: A 30-year-old woman underwent bilateral myopic LASIK. Eight weeks postoperatively, the patient experienced blurred vision in the left and right eyes. Fundus examination showed focal whitish patches in the parafoveal and juxtafoveal areas and lack of foveal reflex in both eyes. A diagnosis of retinal phlebitis with cystoid macular edema was made, which was treated with oral corticosteroids with tapering dose.

RESULTS: Visual acuity returned to normal and the whitish fundus patches decreased in number and size in both eyes.

CONCLUSIONS: Surgeons should be aware of potential risks and retinal complications associated with LASIK. [J Refract Surg. 2005;21:501-504.]
Wavefront Aberration Outcomes of LASIK for High Myopia and High Hyperopia
Authors: Pesudovs Konrad
Published: December 2019

ABSTRACT

PURPOSE: To determine the higher order aberrations at the corneal first surface after conventional LASIK for high myopia and high hyperopia.

METHODS: This was a retrospective study using a convenience sample with subjects divided into five groups by level of refractive correction. Group 1 were normals, having no eye disease or previous surgery, but may have had refractive error. Group 2 had low myopia (-1.00 to -5.87 D), group 3 high myopia (>6.00 D), group 4 low hyperopia (+1.00 to +3.87 D), and group 5 high hyperopia (>4.00 D). LASIK was performed using a Technolas 217 laser. Corneal topography was taken with Orbscan II, and Placido data exported to VOLPro software v6.71. Wavefront aberrations were determined fora 6.0-mm pupil.

RESULTS: The study included 264 subjects-group 1 (normal), n =204; group 2 (low myopia), n =20; group 3 (high myopia), n =20; group 4 (low hyperopia), n =10; and group 5 (high hyperopia), n =10. The spherical equivalent refractive error corrected (mean±SD) was 0.00±0.00 D in group 1, -3.92±1.47 D in group 2, -9.53±2.06 D in group 3, +2.49±0.51 D in group 4, and +5.54?1.22 D in group 5. The total higher order root-mean-square (RMS) wavefront aberration was 0.38±0.07 µm in group 1, 0.69±0.22 µm in group 2, 1.36±1.79 µm in group 3, 0.64±0.34 µm in group 4, and 1.76±0.54 µm in group 5. Spherical aberration was 0.25±0.06µm in group 1, 0.45±0.11µm in group 2, 0.64±0.29µm in group 3, -0.11±0.15 µm in group 4, and -0.56±0.22µm in group 5. The refractive correction (Rx) was highly correlated to total higher order RMS for myopic correction higher order RMS =0.38 -0.07Rx, R
p 2
=0.52, and for hyperopic correction higher order RMS=O. 18 +0.28Rx, R
p 2
=0.75.

CONCLUSIONS: Conventional LASIK increases all corneal higher order aberrations with induced aberrations increasing with the magnitude of refractive correction. High refractive corrections, both myopic (>6.00 D) and hyperopic (>5.00 D), can lead to very high levels of corneal higher order aberrations. [J Refract Surg. 2005;21: S508-S512.]
A New Night Vision Disturbances Parameter and Contrast Sensitivity as Indicators of Success in Wavefront-guided Enhancement
Authors: Reinstein Dan Z , Archer Timothy J , Couch Darren , Schroeder Eckhard , Wottke Matthias
Published: December 2019

ABSTRACT

PURPOSE: To determine the level of success of wavefront-guided repair of night vision disturbances after conventional (Munnerlyn) myopic LASIK using a new parameter to describe higher order aberrations, and to compare the improvements to matched myopic LASIK controls who were symptom-free.

METHODS: We developed a single parameter metric to represent raw spherical aberration (RAWS) to functionally describe the cumulative spherical aberration for an eye over a range of physiological pupil sizes. To derive the RAWS parameter, spherical aberration is plotted over pupil analysis zones from 3000 to 6000 µm. The RAWS parameter (unit = µm
p 2
) is then equal to the area under the plot. Sixteen eyes treated for night vision disturbances by wavefront-guided repair were each compared to the mean of four matched control eyes (total 64 eyes) treated by aspheric myopic ablation and without night vision disturbances. Contrast sensitivity and RAWs parameter for spherical aberration were determined for each of the repair eyes and control eyes before and after surgery.

RESULTS: Following wavefront-guided repair, 76% of eyes were subjectively reported to have night vision disturbances improved by at least 80%. The percentage of eyes within normal contrast range increased from 25% to 80% following wavefront-guided repair (P<.05). For the control eyes, LASIK increased RAWS by 126% (RAWS was 122 µm
p 2
preoperatively and 276 µm
p 2
post-operatively). For the night vision disturbances repair eye group, RAWS at presentation was 104% (563 µm
p 2
) above the respective postoperative RAWS control eyes. Following wavefront-guided repair, RAWS was decreased (P<.05) to only 49% (410 µm
p 2
) above the postoperative control group.

CONCLUSIONS: The RAWS parameter enabled a single digit descriptor of overall higher order aberrations for an eye over the principal physiological pupil range. By comparing RAWS parameter changes in wavefront-guided repair eyes to matched postoperative asymptomatic eyes, we were able to determine the magnitude of the deficit in the symptomatic eyes and the relative efficacy of wavefront-guided repair.

Authors: Dvali Merab L , Tsintsadze Nana A , Mirtskhulava Sophia I
Published: December 2019

ABSTRACT

PURPOSE: To evaluate the results of hyperopic LASIK in children and adolescents with accommodative strabismus and refractive amblyopia.

METHODS: The procedures were conducted by standard methods of LASIK using a Technolas 217C excimer laser (Bausch & Lomb, Rochester, NY).

RESULTS: LASIK resolved the accommodative components of strabismus by achieving stabilization of visual acuity and decrease (or disappearance) of amblyopia degree. All patients achieved binocular vision.

CONCLUSIONS: Excimer laser correction of hyperopia and hyperopic astigmatism in children and adolescents has the potential to correct refractive errors, improve visual function in amblyopic eyes, correct accommodative strabismus, and improve binocular vision.

Authors: Ciccio Amy E , Durrie Daniel S , Stahl Jason E , Schwendeman Frank
Published: December 2019

ABSTRACT

PURPOSE: To compare the measured difference and degree of cyclotorsion in eyes undergoing customized laser ablation between the time of wavefront measurement and laser refractive surgery.

METHODS: The degree of cyclotorsion was measured in 1019 consecutive eyes of 732 patients who underwent wavefront-guided corneal ablation for the treatment of myopia with or without astigmatism with the Alcon LADARVision excimer laser. Prior to obtaining the wavefront measurement, the horizontal axis of each eye was marked. Cyclotorsional alignment was measured on the supine patient prior to beginning the laser.

RESULTS: The predominant trend was for excyclotorsion. The total range of torsion in degrees was 0.5? to 17.5? (mean: 4.05?2.9?). Cyclotorsion >2? occurred in 68% of all eyes. In the right eyes, 83% excyclotorted, 14% incyclotorted, and 3% displayed no torsion. In the left eyes, 62% excyclotorted, 34% incyclotorted, and 4% exhibited no torsion. In a subset of 112 patients undergoing simultaneous bilateral surgery, 46% displayed bilateral excyclotorsion and 1.7% displayed bilateral incyclotorsion.

CONCLUSIONS: In this study, the majority of eyes had a low to moderate amount of cyclotorsion observed with the change of orientation from seated to supine position. Excyclotorsion was the predominant pattern. Proper registration prior to wavefront-guided corneal ablation is essential for proper correction of astigmatism and higher order aberrations to achieve optimal visual outcomes.

The Syntagma musicum in Lutheran Organ Sermons of the Seventeenth and the Eighteenth Centuries
Authors: Braun Lucinde
Published: December 2019

Based on a corpus of organ sermons, this paper analyses the theological reception of the Syntagma musicum. As early as 1621 Michael Praetorius’s treatise was explored for the first time by a Lutheran pastor. In 1624, it stimulated Conrad Dieterich to include a description of the Ulm organ into his sermon. After the Thirty Years’ War Michael Praetorius’s work became a regular part of the scholarly apparatus of the sermons. Model sermons and homiletic handbooks helped to shape a distinctive musical-theological discourse. As an example of intercultural exchange the transmission of several excerpts from Girolamo Dirutas Il Transilvano translated by Michael Praetorius merits special attention.

Published: December 2019

The Technical University of Madrid, within the Spanish context, has profited from the introduction of a System of Internal Quality Assurance to build a road on the grounds of previous work on the culture of ethics in engineering. This way may drive the students training to incorporate in their curricula, leadership instruments that can be used for the recognition and acquisition of social responsibility. The road is paved with various educational elements, either mandatory, such as the “Mentoring Project” (peer support program), or optional, such as “Monitoring” (peer academic support program), “Ethics and Values in Engineering” (with social entrepreneurship projects) and “Service-Learning” (methodology that combines learning objectives with community service). This strategy, combined with the convergence of the European Higher Education Area, allows selecting those students who are able to integrate in their professional assets the idea and commitment of making the human development more sustainable, since the named experiences work towards the Sustainable Development Goals.
Effects of an Innovative Learning Culture on the Competences of Learners
Authors: Barabasch Antje , Keller Anna , Caldart Dominic
Published: December 2019

Competence demands for employees in the ICT sector have increased and new job profiles have been necessary, especially in the telecommunications industry. New competence requests challenge conventional qualifications and learning pathways, such as the apprenticeship route in Switzerland. For management the challenge is not only to change structural conditions of vocational learning at the workplace, but also attitudes, beliefs, and values regarding the ways in which apprentices are treated, the ways in which communication takes place, tasks are distributed, or expectations are expressed that require a transformation. The chapter introduces an enterprise case study. It elaborates on aspects, such as structural conditions for an innovative learning culture and measures for competence development, such as supporting agility, a trustful communication at eye level, as well as the flexibility in offering guidance.
The Concept of Logistics Performance in International Trade Framework
Authors: Bilgin Cevat
Published: December 2019

An increased need for international logistics has emerged with a higher degree of globalization. The quality of logistics services determines the degree of a country's involvement in global trade. In this chapter, the concept of logistics performance in the international trade context is discussed, then the measurement problems of logistics performance are discussed. The links between logistics, trade, and growth are evaluated theoretically. Policymakers and researchers have been widely using Logistics Performance Index (LPI) developed by the World Bank. LPI provides a general information of logistics costs, customs processes, and the quality of the necessary infrastructure for transportation for each country. In this chapter, the definition, the methodology, and the aspects of the indicator LPI, its content and components, and the relations between LPI and some economic factors such as growth and foreign trade, are elaborated. The econometric modelling methods are used to analyze the relations between LPI and economic factors.

Published: December 2019

Liquefied petroleum gas is used as an energy source in many areas of the world. It is among the most important fuels used worldwide. Transport of this type of petroleum products between ports is carried out on a large scale. These cargoes are transported in ship types called LPG tankers. Transported LPG gas formation must be carried in liquid form. Particularly in these liquid formations, the transportation of the LPG vessels is divided into different types and it is carried under the name of Fully Refrigerated, which authors call full cooling. LPG is a highly sensitive, flammable, and explosive property, but it is also necessary to know special precautions regarding its transportation. Load operations are difficult processes for LPG tankers. The most complex of these processes is the change of load called grade change. The chapter guides LPG vessels' workers and students in the education process.

Today's innovative systems and approaches handle the supply chain function in the healthcare institutions in a broader way even though it is generally accepted as the material management. The supply in the hospitals is a comprehensive issue that covers regular material supply, the quality and the speed of services and maintenance process. As in the other sectors, the healthcare sector wants to get the required goods and services in the places where they are needed, when they are needed, with the desired quality and price. Besides, hospitals try to produce low-cost services because of today's competition conditions and increasing number of private hospitals. Today's supply chain management is carried out to decrease the costs, reduce the lean, and increase the quality.

A Risk Integration Framework for the Service-Oriented Enterprise
Authors: Grandry Eric , Feltus Christophe , Dubois Eric
Published: December 2019

Enterprise architecture management provides the mechanism for governing enterprise transformations required by changes in the environment. In this article, the authors focus on changes that result from the analysis of information system risks and of their impacts on the services delivered by the enterprise. The authors present how the concepts of an information system risks management domain can be integrated into the ArchiMate enterprise architecture modelling language. This article approaches the conceptual integration in two design cycles: first, this article will consider information security risks, and then the authors generalize to information system risks. Additionally, the authors illustrate the application of the proposed approach and demonstrate the benefits of the integrated model through the handling of a case study, first in the domain of information security, and then in the domain of information privacy. The generalized risk-oriented EA model leads to a risk integration framework for the service-oriented enterprise.

Authors: Alrob Mohamed Mahmoud Abo , Jaaron Ayham A. M.
Published: December 2019

Resilience has been viewed as the critical component behind Islamic banking organizations' ability to respond and compete during crisis. However, there seems to be scarcity of empirical attempts to explore the determinants of stronger resilience in Islamic banking organizations. This article is an attempt to develop a managerial framework of Islamic banking organizations that identifies these determinants of improved resilience. Two case studies were conducted in two Islamic banks in Palestine. Data were collected via semi-structured interviews, observations, and archival documents, followed by the use of the Resilience Benchmark Tool (RBT). Cross-case analysis of the results shows that organizational resilience in banking organizations is characterized by two dimensional determinants for improving organizational resilience; planning and adaptive capacity along with a set of ten resilience enhancing factors. The article demonstrates important dynamics of how resilient capabilities can be incorporated into the managerial models of banking organizations during turmoil.
Vertical and Community-Based Crowdfunding Platforms
Authors: Greco Tomaso
Published: December 2019

If the inherent nature of the horizontal crowdfunding platforms makes the relationship between campaign creator and backers basically without intermediation of the platform, in the case of vertical platforms there are different and sometimes complex levels of intermediation. The vertical crowdfunding platforms can be considered more than a subset of the horizontal crowdfunding, as an independent system of relationships and rules which has in common with the horizontal crowdfunding a large part of the fundraising methods, but that is also profoundly different with respect to the aggregative procedures and the system of rules.
Cloud Service Footprint (CSF)
Authors: Shalan Mohammad
Published: December 2019

Cloud Computing (CC) services have made substantive advances in the past few years. It is rapidly changing the landscape of technology, and energizing the long-held promise of utility computing. Successful jump into CC is a considerable task, since the surroundings are not yet mature and the accompanied risk and governance frameworks are still evolving. This effort aims to portray an identity for CC services by employing risk and governance directions among other elements and techniques. Cloud Service Footprint (CSF) is considering practical aspects surrounding the CC paradigm and prescribing the associated directions. CSF will help Cloud Service Providers (CSPs) to characterize their service and benchmark themselves. The Client Enterprises (CEs) can utilize CSF dimensions to find a better way to navigate through CC service arena and to understand its parameters. Along with cost and functional capabilities, the Cloud Service Footprint (CSF) can provide enough information for business executives to evaluate CC services and make informed decisions.
Continuous Improvement Relationship to Risk Management
Authors: Galli Brian J.
Published: December 2019

In order for a company to economically survive, it needs to compete with a highly competitive market. The world is changing fast, adding different types of risks to companies. So, companies need to not only meet requirements but also exceed them. At the same time, companies are required to lower the level of risks they may encounter. As a result, continuous improvement and risk management should be key factors to insure company success. This study explores the relationship between the two concepts and gives examples where the interconnections between them exist. Also, the study explains the important key components of continuous improvement and the classifications of risk management. Finally, this article focuses on three aspects, managing complaints, developing strategy, and creating a suitable culture. These aspects are evaluated based on the relationship between continuous improvement and risk management.
Crowdfunding, Entrepreneurship, and Design Education
Authors: Ding Zhou , Jiabei Jiang
Published: December 2019

The purpose of this paper is to develop further insights into micro-entrepreneurship programs participated in by Chinese industrial designers. A model of creative thinking is employed to explain the campaign creation process. A case study research in sample design entrepreneurs was designed and conducted, and it was composed of three steps: preparing for data collection, collecting the evidences, and analyzing the evidences. It was found that five main defects in creative thinking work as obstacles to crowdfunding success. In order to overcome these drawbacks, it is suggested that designers involved in micro-entrepreneurship programs should acquire the abilities of building prototypes, following the design procedure, finding and solving problems, defining ideation and applying the evaluation methods. Current findings and future study can contribute to the curriculum development for China's industrial design education.

Intermediating Crowdfunding
Authors: Heminway Joan MacLeod
Published: December 2019

The principals in business finance transactions most typically are the focus of commentaries and studies. Intermediaries often are forgotten—or at least are of secondary concern. The growing academic and popular literature on crowdfunding exemplifies these larger trends. This chapter focuses broadly on a description of crowdfunding intermediation in a preliminary effort to address this imbalance. Specifically, the chapter focuses most closely on (a) identifying and categorizing the types of intermediaries involved in crowdfunded financings of businesses and projects and (b) making related observations. This exploration of crowdfunding intermediaries: isolates expertise, standardization, and disclosure as key values in crowdfunding intermediation; exposes the central role and critical nature of the crowdfunding platform as a crowdfunding intermediary; and notes certain resulting concerns and considerations. Ultimately, additional research is needed to provide better information and guidance to potential and actual crowdfunding participants, policymakers, and enforcement agents.

Fostering Environmental Performance Management within Indian SMEs
Authors: Nulkar Gurudas
Published: December 2019

Research and discussions on environmental sustainability of businesses generally focus on large corporations. Their environmental impacts are more likely to be noticed while small and medium enterprises (SME) are largely ignored. With a small scale of operations, SMEs are generally perceived to have less environmental impacts. However, as larger corporations outsource their manufacturing to SMEs the environmental burden shifts within their supply chain. This research was conducted within manufacturing SMEs in industrial markets (B2B) in Pune, India. In depth interviews with large and small firms helped develop the conceptual model and the questionnaire. Responses from 60 SMEs were analysed. The research identified factors like owner awareness, barriers and influencers to green practices and categorized environmental practices within product life cycle. The results showed that owners with high awareness levels had advanced environmental activities. The strength of barriers and influencers was established and the author makes recommendations based on these findings.

Exploring the Research Domain of IT Governance in the SME Context
Authors: Huygh Tim , De Haes Steven
Published: December 2019

This research aims to explore the research domain of IT governance in the SME context. To meet this objective, a small systematic literature review procedure is used. Results indicate that IT governance in the SME context has been researched previously, albeit not extensively. There seems to be consensus among authors that IT governance is important for SMEs as well as larger organizations. Additionally, many authors indicate that SME specificities will likely influence the nature and implementation of IT governance in the SME context. There also appears to be no great variety in research strategies used in this niche research domain. Regarding the contemporary state of IT governance in SMEs, authors seem to indicate that there is room for improvement. Finally, there is no published framework for IT governance that is tailored for SMEs, although the need for this is directly reported in the literature. This paper concludes by discussing some potential directions for future research, starting from the state-of-the-art of the research domain.
