Concert Halls

The 1980s are likely to see a continuation of the trend of the past 25 years of an expansion in the quantity, and improvement in the quality, of public music making. Concert halls are usually prestigious buildings, and often no expense is spared to make the acoustics as good as possible, but the design problems are still formidable. In the 1980s some considerable help in design may be expected from scale models and computer simulation. And electronic aids for acoustics may become more common. The problems of multi-purpose halls are rather different; the conflicting acoustic requirements for speech and for music have to be reconciled, and cost is important. Here electronic techniques may play a considerable part in the future.

Research on the strategic organization of time often assumes that collective efforts are motivated by and oriented toward achieving desirable, although not necessarily well-defined, future states. In situations surrounded by uncertainty where work has to proceed urgently to avoid an impending disaster, however, temporal work is guided by engaging with both desirable and undesirable future outcomes. Drawing on a real-time, in-depth study of the inception of the Restoration and Renewal program of the Palace of Westminster, we investigate how organizational actors develop a strategy for an uncertain and highly contested future while safeguarding ongoing operations in the present and preserving the heritage of the past. Anticipation of undesirable future events played a crucial role in mobilizing collective efforts to move forward. We develop a model of future desirability in temporal work to identify how actors construct, link, and navigate interpretations of desirable and undesirable futures in their attempts to create a viable path of action. By conceptualizing temporal work based on the phenomenological quality of the future, we advance understanding of the strategic organization of time in pluralistic contexts characterized by uncertainty and urgency.

Balconies are normally used in large auditoria such as concert halls or opera houses, to increase seating capacity or to give better view for a distinguished group of the audience. When ray-tracing based computer models are applied to study the acoustical quality of these auditoria, the alteration of the sound field due to balcony fronts is normally unobservable, because of the relative small size of the balcony fronts in the auditorium. Furthermore, most diffuse reflection ray-tracing methods are not based on direct wave acoustics but on an approximation of the scattering effect. In practice, experience shows that balcony fronts give additional warmth to music. This effect is more prominent when singers perform in traditional horseshoe shaped opera houses with multi-levels balconies. This paper describes modelling of scattering from balcony fronts using a theoretical wave approach, in which the incident wave front is not plane but spherical. A computer simulation illustrates the scattering of sound that takes place when the wavefront impinges on the surface of the balcony fronts.

Hatsune Miku is immensely popular. Since debuting in 2007 over 10,000 songs have been produced for her and she has appeared in 250,000 videos on-line. 4000 professional recordings have been released of her songs and numerous dolls, games, and other seemingly unlimited forms of merchandise feature her big violet eyes, floor-grazing blue pigtails and futuristic schoolgirl uniform. Hatsune Miku is actually a type of vocal synthesizer software produced by Yamaha and marketed by Crypton known as “Vocaloid 2.” Other vocal synthesizer softwares with associated characters have come before, but none have enjoyed the same success as Hatsune Miku. Hatsune Miku’s performance – whether in amateur produced songs posted on Piapro or in multi-million-dollar live 3D productions – raises many questions about the potential effects of Vocaloid software on the future of making music in Japan. Through the technical production of songs, the quality of vocals, and her presence on stage, Hatsune Miku slides back and forth between a position of classic passivity to one of female empowerment and feminist approaches to equity. This chapter further explores Hatsune Miku’s complicated position as a performer who perpetuates an objectified position of women in popular music while at the same time promotes democratic music making.

           The background of this study is the uniqueness of the management zakat fitrah in Nuguk hamlet by giving to those considered to have a match or harmony, with the hope that the person receiving the zakat fitrah can become the mediator of health, tranquility for the life of muzakki in the future. This article is the result of qualitative field research with descriptive-analysis methods. The conclusion of this study is the management of zakat fitrah in Nuguk hamlet is performed with the classical management model, a model that’s still very simple with the way of muzakki delivering zakat fitrah to the ‘amil individually at their home respectively. The trust among the community in Nuguk hamlet is excessive and not following the ideal concept of shari’a. The management according to the al-Qur`an includes three important element, namely : collection  (Qs. At-Taubah [9] : 103), data collection and distribution (Qs. al-Baqarah [2] : 282 and Qs. At-Taubah [9] : 60), and utilization by using ‘traditional consumptive’ model, that’s zakat fitrah is directly distributed to mustahik through the ‘amil intermediary. The factors the contribute to the weaknesses of zakat fitrah management in Nuguk hamlet include : 1) low quality of education, and 2) oriented to the past management Abstrak            Latar belakang kajian ini adalah karena ada keunikan manajeman zakat fitrah di Dusun Nuguk, yaitu dengan cara menyerahkan kepada orang yang dianggap cocok atau serasi, dengan harapan orang yang menerima zakat fitrah tersebut dapat menjadi perantara kesehatan, ketenteraman bagi kehidupan muzakki dikemudian hari. Artikel ini merupakan hasil dari penelitian kualitatif lapangan dengan metode deskriptif-analisis. Adapun kesimpulan dari penelitian ini adalah manajemen zakat fitrah di Dusun Nuguk dilakukan dengan model manajemen klasik, yaitu suatu model manajemen yang masih sangat sederhana dengan cara muzakki menyerahkan zakat fitrah kepada ‘amil yang bersifat perorangan di rumah ‘amil masing-masing. Kepercayaan masyarakat Dusun Nuguk yang berlebihan kepada ‘amil dirasa kurang sesuai dengan konsep ideal syariat. Adapun manajemen menurut Alquran meliputi tiga unsur penting, yaitu : Pengumpulan (Qs. At-Taubah [9] : 103), Pendataan dan Pendistribusian (Qs. Al-Baqarah [2] : 282 dan Qs. At-Taubah [9] : 60, serta Pendayagunaan dengan menggunakan model ‘konsumtif tradisional’, yaitu zakat fitrah langsung didistribusikan kepada mustahik melalui perantara ‘amil. Faktor yang menyebabkan lemehnya mananjemen zakat fitrah di dusun Nuguk ada dua, yaitu : (1) Rendahnya mutu pendidikan, dan (2) Berorientasi pada manajemen masa lalu.

Our paper is a report on the past, current and future state of the endangered Pite Saami language (aka: Arjeplog Saami) spoken in Swedish Lapland. Our primary data come from interviews with Pite Saami individuals and our field observations. We estimate the vitality of Pite Saami based on the UNESCO Language Vitality Scale, taking into consideration factors such as the number of speakers, language attitudes and the quality of documentation. We also discuss the possible reasons for the decline of Pite Saami, report on the speakers’ views of other Saami languages and Swedish, consider whether there is a specific Pite Saami identity, describe revitalization efforts already taking place, and discuss the future prospects of the language.

Multiple sclerosis (MS) is an autoimmune disabling disease of the central nervous system, and can lead to a wide range of symptoms. Although the most common form of MS is relapsing-remitting, most of the patients also will develop disability in the future due to the natural course of the disease.1,2 The disease onset mostly occurs in 27 years of age.3 Therefore, considering the symptoms and complications of the disease, it can virtually affect the whole life of the patient. Unfortunately, there is not any accurate study of the opinions of patients with MS regarding their illness. However, in the daily work of treatment, one of the well-known cases of severe discomfort expressed by patients is the fear of future disability. This issue is aggravated when a person starts to lose abilities. When the patient experiences disability in walking and a decrease in his/her daily activities, thinking about the future becomes one of his/her major concerns. Most patients express these concerns in their visits. However, a patient who has other abilities such as poetry, writing a story, or painting, can more effectively portray concerns. The painting reported here is the allegorical view of a patient about her disability. The patient is a 37-year-old woman who has had MS for 15 years. Her illness started with the right eye optic neuritis. She has had six attacks during this period and, after 9 years, her disease entered the secondary progressive phase. Her symptom in this stage was the weakness of the right lower extremity, which was gradually deteriorating such as difficulty in walking. Now, she is unable to walk without help. This disability has affected all aspects of her life, and has greatly diminished her quality of life. She has been interested in drawing since childhood, and has drawn as a non-professional artist. One of her paintings reported here (Figure 1), according to the patient herself, reflects her perception and grief over her progressive disability. She believes that she should say goodbye to her ability and good days of the past. She painted herself as someone (when she could walk unrestrictedly) moving away along with a balloon

Quality Evidence

Abstract Objective Although medication abortion has become more common in high-income countries, the procedure has not yet met early expectations for widening access to abortion. High-quality evidence can serve as a catalyst for changes in policy and practice. To direct research priorities, it is important to understand where quality evidence is concentrated and where gaps remain. High-income countries have developed a body of evidence that may have implications for the future of medication abortion. This literature review assesses the characteristics and quality of published studies on medication abortion conducted in the last 10 years in high-income countries and indicates future areas for research to advance policy and practice, and broaden access. Study design A structured search for literature resulted in 207 included studies. A framework based upon the World Health Organization definition of sub-tasks for medication abortion was developed to categorize research by recognized stages of the medication abortion process. Using an iterative and inductive approach, additional sub-themes were created under each of these categories. Established quality assessment frameworks were drawn upon to gauge the internal and external validity of the included research. Results Studies in the US and the UK have dominated research on MA in high-income countries. The political and social contexts of these countries will have shaped of this body of research. The past decade of research has focused largely on clinical aspects of medication abortion. Conclusion Researchers should consider refocusing energies toward testing service delivery approaches demonstrating promise and prioritizing research that has broader generalizability and relevance outside of narrow clinical contexts. Plain English summary Although medication abortion is more commonly available worldwide, it is not being used as often as people thought it would be, particularly in high income countries. In order to encourage changes in policy and practice that would allow greater use, we need good quality evidence. If we can understand where we do not have enough research and where we have good amounts of research, we can determine where to invest energies in further studies. Many high-income countries have produced research on medication abortion that could influence policy and practice in similarly resourced contexts. I conducted a literature review to be able to understand the type and quality of research on medication abortion conducted in high-income countries in the past 10 years. I conducted the review in an organized way to make sure that the papers reviewed discussed studies that I thought would be important for answering this question. The literature review found 207 papers. Each of these papers were reviewed and organized them by theme. I also used existing methods to determinine the quality of each study. Most of the research came from the US and the UK. Furthermore, most of the research conducted in the past 10 years was focused on clinical studies of medication abortion. In future studies, researchers should focus more on new ways of providing medication abortion to women that offers greater access. Also, the studies should be designed so that the results have meaning for a broader group of people or situations beyond where the study was done.

The Difference

The development of biomass has been an important issue for the past several decades and would remain to be attractive in the future due to its clean, renewable, and carbon–neutral properties. The use of Empty Fruit Bunch (EFB) has been the condition of fibre and conditions of EFB is still fresh. The fiber used has been cut to size between ± 0.5 mm to 5 mm. The purpose of this research is to determine the effect of difference press angle to the quality of briquette. Effect of the angle of the mold on the duration of combustion shows the difference in the time value that is not significant between the angles 65°, 55° and 45°. The rotation of the screw shaft slows down at an angle of 45° with a round of 84.5 rpm, while the rotation of the shaft has increased in rotation at 65° angle with rotation of 90.6 rpm. Differences in the cone angle affect the value of the burning time of the specimen and the rotation of the screw shaft so that it affects the engine performance.

Economic Thinking

Economics, as it is frequently taught nowadays, consists largely of supply and demand curves. Within their graceful lines are contained the wisdom of the ages—the key to the past and the barometer of the future. If superimposed on one another, these curves have all the esthetic quality of dynamistic drawings. So completely have they dominated economic thinking that when a group of economists considered the possibility of founding an Economic History Association, their first impulse was to establish a demand curve. This was done, as Professor Heaton has intimated, by Miss Anne Bezanson, who canvassed the field. She discovered that four hundred people could be counted upon immediately to support a Journal of Economic History.

During the COVID-19 pandemic, companies coped and still must deal with uncertainty greater than ever. Due to the unpredictability of consumer demand, the incredible growth in demand for certain products, dramatic fluctuations in supply chains, and general economic instability, the future still looks uncertain. It is up to the manufacturers to determine how things will be sorted out in the new normality, i.e., which changes will be long-lasting or even permanent. Lean production has emerged in recent decades as an excellent solution to increase the economy and quality of production and meet customer needs. In the market conditions affected by the COVID-19 pandemic, producers work in a significantly changed environment, and many wonder whether lean production remains as relevant and valuable as in the past. The paper discusses lean production from different aspects as the essence of the principles of the lean concept, events during the pandemic, and expectations in the post-Covid period. We used some examples to support the analysis of factors that negatively affect the course of lean production as well as some bright examples of companies that took advantage of lean production in the new conditions. The conclusions consider answer whether lean production will survive the consequences of the COVID-19 pandemic.
