Competencies of Modern Musician Entrepreneurs: The Role of Digitalization in the Music Industry

The culture creation industries are undergoing a period of accelerated digitization, globalization, and democratization. The 21st century music industry is bustling with lowered barriers to entry, increased knowledge sharing, and direct to consumer models which have resulted in a gold rush of entrepreneurial opportunities for musicians and increased competition to music firms and superstars. The music industry has been subject to innovative disruption providing valuable insight on the nuances of this paradigm shift for music entrepreneurs and scholars alike. Specifically, I explore competency factors in artist’s journey from musicians to entrepreneurs with successful self-managed careers. Employing Lazear’s Theory of Balanced Skills, I develop a survey instrument and 2x2 framework to discern between high and low levels of entrepreneurial business competencies and high or low levels of artistic competencies including creativity and musical competencies. I conclude by testing survey data from Prolific analyzing the relationships between business competencies, music, creative competencies, financial and non-financial performance, and the moderating role of digital adoption as measured by a questionnaire deployed to 232 active musicians between April and May of 2023. Results identify significant competencies across the 3 domains studied as well as positive and negative moderation by digital acceptance on the relationship between competencies and performance

The analysis of saving behavior :the case of rural households in the Philippines

This study therefore, attempts to examine the saving behaviour of Filipino rural households. Household data gathered by the Agricultural Credit Policy Council (ACPC) of the Philippines during the last quarter of 1987 in selected rural province^ of the Philippines has been analyzed. The Specific objectives of the study are a£ follows: 1) to verify the capacity of rural households in the Philippines to save; 2) to determine the factors that influence saving behaviour; 3) to examine the forms in which savings are held and identify the factors that influence financial savings

An Energy-aware, Fault-tolerant, and Robust Deep Reinforcement Learning based approach for Multi-agent Patrolling Problems

Autonomous vehicles are suited for continuous area patrolling problems. However, finding an optimal patrolling strategy can be challenging for many reasons. Firstly, patrolling environments are often complex and can include unknown environmental factors. Secondly, autonomous vehicles can have failures or hardware constraints, such as limited battery life. Importantly, patrolling large areas often requires multiple agents that need to collectively coordinate their actions. In this work, we consider these limitations and propose an approach based on model-free, deep multi-agent reinforcement learning. In this approach, the agents are trained to automatically recharge themselves when required, to support continuous collective patrolling. A distributed homogeneous multi-agent architecture is proposed, where all patrolling agents execute identical policies locally based on their local observations and shared information. This architecture provides a fault-tolerant and robust patrolling system that can tolerate agent failures and allow supplementary agents to be added to replace failed agents or to increase the overall patrol performance. The solution is validated through simulation experiments from multiple perspectives, including the overall patrol performance, the efficiency of battery recharging strategies, and the overall fault tolerance and robustness

Titan Science with the James Webb Space Telescope (JWST)

The James Webb Space Telescope (JWST), scheduled for launch in 2018, is the successor to the Hubble Space Telescope (HST) but with a significantly larger aperture (6.5 m) and advanced instrumentation focusing on infrared science (0.6-28.0 $\mu$m ). In this paper we examine the potential for scientific investigation of Titan using JWST, primarily with three of the four instruments: NIRSpec, NIRCam and MIRI, noting that science with NIRISS will be complementary. Five core scientific themes are identified: (i) surface (ii) tropospheric clouds (iii) tropospheric gases (iv) stratospheric composition and (v) stratospheric hazes. We discuss each theme in depth, including the scientific purpose, capabilities and limitations of the instrument suite, and suggested observing schemes. We pay particular attention to saturation, which is a problem for all three instruments, but may be alleviated for NIRCam through use of selecting small sub-arrays of the detectors - sufficient to encompass Titan, but with significantly faster read-out times. We find that JWST has very significant potential for advancing Titan science, with a spectral resolution exceeding the Cassini instrument suite at near-infrared wavelengths, and a spatial resolution exceeding HST at the same wavelengths. In particular, JWST will be valuable for time-domain monitoring of Titan, given a five to ten year expected lifetime for the observatory, for example monitoring the seasonal appearance of clouds. JWST observations in the post-Cassini period will complement those of other large facilities such as HST, ALMA, SOFIA and next-generation ground-based telescopes (TMT, GMT, EELT).Comment: 50 pages, including 22 figures and 2 table

Recurrent Perineal Hernia After Benign Pelvic Reconstructive Surgery

Abstract Background: Secondary acquired perineal hernias are rare events usually associated with extensive pelvic surgery. Although most are asymptomatic, when symptoms are present surgical intervention is warranted. There is currently no consensus regarding the management of these hernias. An unusual case of a recurrent perineal hernia following sacrospinous fixation resulting in large bowel incarceration is reported. Case: A 64-year-old woman presented with an anterior vaginal wall prolapse and multiple pelvic-floor defects. She subsequently underwent a sacrospinous fixation and enterocele repair. The enterocele recurred and she underwent a second enterocele repair. Approximately 6 months later, she presented with a perineal hernia that involved an incarceration of the large bowel. Results: The hernia was reduced, the pelvic-floor defect was repaired, and a biologic, absorbable mesh was applied. Approximately 5 months later, the patient presented with a recurrence of the perineal hernia. The hernia was reduced and this time a synthetic, nonabsorbable mesh was used, and there were no signs of recurrence at 6 months' follow-up. Conclusions: Acquired perineal hernias are extremely rare events, especially when they recur and involve large bowel incarceration. Several factors may influence the development and possible recurrence of secondary acquired perineal hernias, including lifestyle, occupation, gestational history, and past medical and surgical history. The use of a nonabsorbable mesh to prevent recurrence is suggested, although current literature reports success rates that are fairly similar for users of both absorbable and nonabsorbable meshes.

Climate change and the kidney

The worldwide increase in temperature has resulted in a marked increase in heat waves (heat extremes) that carries a markedly increased risk for morbidity and mortality. The kidney has a unique role not only in protecting the host from heat and dehydration but also is an important site of heat-associated disease. Here we review the potential impact of global warming and heat extremes on kidney diseases. High temperatures can result in increased core temperatures, dehydration, and blood hyperosmolality. Heatstroke (both clinical and subclinical whole-body hyperthermia) may have a major role in causing both acute kidney disease, leading to increased risk of acute kidney injury from rhabdomyolysis, or heat-induced inflammatory injury to the kidney. Recurrent heat and dehydration can result in chronic kidney disease (CKD) in animals and theoretically plays a role in epidemics of CKD developing in hot regions of the world where workers are exposed to extreme heat. Heat stress and dehydration also has a role in kidney stone formation, and poor hydration habits may increase the risk for recurrent urinary tract infections. The resultant social and economic consequences include disability and loss of productivity and employment. Given the rise in world temperatures, there is a major need to better understand how heat stress can induce kidney disease, how best to provide adequate hydration, and ways to reduce the negative effects of chronic heat exposure.Published versio
