The Impact

Cooperative music making in networked environments has been subject of extensive research, scientific and artistic. Networked music performance (NMP) is attracting renewed interest thanks to the growing availability of effective technology and tools for computer-based communications, especially in the area of distance and blended learning applications. We propose a conceptual framework for NMP research and design in the context of classical chamber music practice and learning: presence-related constructs and objective quality metrics are used to problematize and systematize the many factors affecting the experience of studying and practicing music in a networked environment. To this end, a preliminary NMP experiment on the effect of latency on chamber music duos experience and quality of the performance is introduced. The degree of involvement, perceived coherence, and immersion of the NMP environment are here combined with measures on the networked performance, including tempo trends and misalignments from the shared score. Early results on the impact of temporal factors on NMP musical interaction are outlined, and their methodological implications for the design of pedagogical applications are discussed.

Simulation Exercises

Purpose – Church giving and attendance are two important indicators of church health and performance. In the literature, they are usually understood to be simultaneously determined. The purpose of this paper is to estimate if there a sustainable church congregation size using Wintrobe’s (1998) dictatorship model. The authors want to examine the impact of youth and adult ministry as well. Design/methodology/approach – Using the data collected from among Canadian Baptist churches in Eastern Canada, this study investigates the factors affecting the level of the two indicators by the panel-instrumental variable technique. Applying Wintrobe’s (1998) political economy model on dictatorship, the equilibrium level of worship attendance and giving is predicted. Findings – Through various simulation exercises, the actual church congregation sizes is approximately 50 percent of the predicted value, implying inefficiency and misallocation of church resources. The paper concludes with insights on effective ways church leaders can allocate scarce resources to promote growth within churches. Originality/value – The authors are the only researchers getting the permission from the Atlantic Canada Baptist Convention to use their mega data set on church giving and congregation sizes as per the authors’ knowledge. The authors are also applying a theoretical model on dictatorship to religious/not for profits organizations.

Musical Interaction

The mapping problem is inherent to digital musical instruments (DMIs), which require, at the very least, an association between physical gestures and digital synthesis algorithms to transform human bodily performance into sound. This article considers the DMI mapping problem in the context of the creation and performance of a heterogeneous computer chamber music piece, a trio for violin, biosensors, and computer. Our discussion situates the DMI mapping problem within the broader set of interdependent musical interaction issues that surfaced during the composition and rehearsal of the trio. Through descriptions of the development of the piece, development of the hardware and software interfaces, lessons learned through rehearsal, and self-reporting by the participants, the rich musical possibilities and technical challenges of the integration of digital musical instruments into computer chamber music are demonstrated.

Longfin Smelt

Following its listing as threatened under the California Endangered Species Act in 2009, Longfin Smelt (Spirinchus thaleichthys) became a focus of resource managers in the San Francisco Estuary. Water exports were identified as one of the factors affecting Longfin Smelt abundance, and managers were challenged with balancing freshwater flows through the Sacramento-San Joaquin River Delta between human and ecosystem needs. This balance becomes especially challenging during the winter and spring when Longfin Smelt are spawning. Resource managers identified that the impact associated with entrainment of larval Longfin Smelt in the winter was uncertain, and to understand and manage this risk, new data was needed. In 2009 the Smelt Larva Survey was implemented and has since sampled newly hatched larvae from January–March. Here, I analyze this data and ask specific questions regarding distribution and densities of the larvae throughout five regions of the Upper Estuary – Napa River, Suisun, Confluence, Northern Delta, and Southern Delta – with the goal of understanding the spatial and temporal patterns of larval distribution since 2009. I found that larvae were most prevalent in the Suisun, Confluence, and Northern Delta regions, and less common in the Southern Delta and Napa River regions. Larval Longfin Smelt densities changed following a recent drought and record low population abundances. Median per-station averaged densities ranged from 154 to 274 fish per 1,000 m3 between 2009 and 2013 but declined to 1 to 65 fish per 1,000 m3 from 2014 to 2019. This survey data demonstrates that Longfin Smelt reproductive output has declined since their listing in 2009 and that their distribution into the Southern Delta is low relative to the rest of the Upper Estuary. These results reaffirm the species’ continued decline since its listing, and that improving the abundance of spawning adults is one of the many important steps needed for long-term recovery and resilience.

<p>Performance audit, compared to the traditional financial and compliance audits, is a relatively new innovation that emerged amidst accountability concerns in the public sector. Economic crises, ministerial scandal and inefficiencies were among the impetus that led the public to demand better performance and greater accountability in the public sector, and performance audit was among the many responses to such demand. In New Zealand, performance audit is carried out by the Controller and Auditor General (the AG) under the mandate granted by the Public Audit Act 2001. Adapting the methodology from grounded theory, this study looks at the impact of performance audit on seven entities audited in 2006 by the AG. This study found that the entities were impacted through the manifestation of implemented audit recommendations and the attainment of performance audit goals. In particular, there is a high acceptance and implementation rate to the audit recommendations made in the seven audits. The implementation of accepted recommendations consequently led to the changes within the entities in terms of managerial practices, as well as internal systems and processes. In some entities, these changes were translated into performance improvement, where the entities experienced changes in the way that they carried out their operations. However, based on interviewees' accounts being the auditees of the audits, most interviewees viewed performance audit as having a greater role for performance accountability compared to performance improvement. Whilst the auditees found the audit recommendations useful, the impact on performance in their view has not been significant. Rather, the auditees viewed performance audit as having a more important role as an assurance tool in terms of their accountability to the public.</p>

<p>Performing music together over a public network while being located at a distance from each other necessarily means performing under a particular set of technical and performative constraints. These constraints are antithetical to—and make cumbersome—the performance of tightly synchronised music, which traditionally depends on the conditions of transmission stability, ultra-low latency, and shared presence. These conditions are experienced optimally only when musicians perform at the same time and in the same place. Except for specialized private network services, public networks are inherently latent and unstable, which disrupts musicians’ ability to achieve precise vertical synchronisation and create an environment where approaches to music performance and composition must be reconsidered. It is widely considered that these conditions mean that networked music performance is a future genre for when network latencies and throughput improve, or one that is currently reserved for high-end heavily optimised networks afforded by institutions and not individuals, or one that is primarily reserved for improvisatory or aleatoric composition and performance techniques. I disagree that networked music is dependent on access to advanced Internet technologies and suggest that music compositions for networked music performance can be highly successful over regular broadband conditions when the composer considers the limitations as opportunities for new creative strategies and aesthetic approaches. In this exegesis, I outline the constraints that prove that while networked music performance is latent, asynchronous, multi-located, multi-authorial, and hopelessly, intrinsically, and passionately digitally mediated, these constraints provide rich creative opportunities for the composition and performance of synchronised and resonant music. I introduce four aesthetic approaches, which I determine as being critical towards the development of networked music: 1) postvertical harmony, where the asynchronous arrival of signals ruptures the harmonic experience; 2) new timbral fusions created through multi-located resonant sources; 3) a contribution to performative relationships through the generation and transmission of vital information in the musical score and through the development of new technologies for facilitating performer synchronisation; and 4) the post-digital experience, where all digital means of manipulation are permitted and embraced, leading to new ways of listening to and forming reproduced realities. Each of these four aesthetic approaches are considered individually in relation to the core constraints, through discussion of the present-day technical conditions, and how each of these approaches are applied to my musical portfolio through practical illustration.</p>

Am Processes

The interest in additive manufacturing (AM) processes is constantly increasing due to the many advantages they offer. To this end, a variety of modelling techniques for the plethora of the AM mechanisms has been proposed. However, the process modelling complexity, a term that can be used in order to define the level of detail of the simulations, has not been clearly addressed so far. In particular, one important aspect that is common in all the AM processes is the movement of the head, which directly affects part quality and build time. The knowledge of the entire progression of the phenomenon is a key aspect for the optimization of the path as well as the speed evolution in time of the head. In this study, a metamodeling framework for AM is presented, aiming to increase the practicality of simulations that investigate the effect of the movement of the head on part quality. The existing AM process groups have been classified based on three parameters/axes: temperature of the process, complexity, and part size, where the complexity has been modelled using a dedicated heuristic metric, based on entropy. To achieve this, a discretized version of the processes implicated variables has been developed, introducing three types of variable: process parameters, key modeling variables and performance indicators. This can lead to an enhanced roadmap for the significance of the variables and the interpretation and use of the various models. The utilized spectrum of AM processes is discussed with respect to the modelling types, namely theoretical/computational and experimental/empirical.

Dynamic Relationships

This book examines the music available to musical consumers in the nineteenth century, and what that music tells us about their tastes, priorities, and activities. The book's social history of chamber music performance places the works of canonic composers such as Schubert, Brahms, and Dvořák in relation to lesser-known but influential peers. The book explores the dynamic relationships among the active agents involved in the creation of Romantic music and shows how each influenced the others' choices in a rich, collaborative environment. In addition to documenting the ways companies acquired and marketed sheet music, the book reveals how the publication and performance of chamber music differed from that of ephemeral piano and song genres or more monumental orchestral and operatic works. Several distinct niche markets existed within the audience for chamber music, and composers created new musical works for their use and enjoyment. The book revises prevailing views of middle-class influence on nineteenth-century musical style and presents new methods for interpreting the meanings of musical works for musicians both past and present.

The Impact

The microstructure and mechanical behavior of welded joints under different technologies were compared for investigating the influence of technological parameters on microstructure and property of weld seam on thick-walled cold-rolled-forming high frequency induction welded (HFIW) tubes. The results show that microstructure of joints consists of a decarburized layer, an overheated area, a recrystallized zone and a partially-recrystallized zone. The opening angle and the welding surface energy (WSE) are important factors affecting microstructure and weld quality. The width of the heat-affected zone is proportional to the WSE. With increase of the WSE, the mean bend angle increases first and decrease later, showing a "mountain-peak" variation. The optimum WSE decreases with decrease of the opening angle because the smaller the opening angle is, the higher the heating efficiency is. The influence of processing parameter on the bending capability of joints is remarkable, while which on the impact toughness can be ignored.
