Published: April 2019

Classifying musical instrument from polyphonic music is a challenging but important task in music information retrieval. This work enables to automatically tag music information, such as genre classification. In previous, almost every work of spectrogram analysis has been used Short Time Fourier Transform (STFT) and Mel Frequency Cepstral Coefficient (MFCC). Recently, sparkgram is researched and used in audio source analysis. Moreover, for deep learning approach, modified convolutional neural networks (CNN) widely have been researched, but many results have not been improved drastically. Instead of improving backbone networks, we have researched on preprocessing process.In this paper, we use CNN and Hilbert Spectral Analysis (HSA) to solve the polyphonic music problem. The HSA is performed at the fixed length of polyphonic music, and a predominant instrument is labeled at its result. As result, we have achieved the state-of-the-art result in IRMAS dataset and 3% performance improvement in individual instrumentsÂ Â
Moderating Effect of Materialism on the Inaction Inertia Phenomenon
Authors: Lee Seongsoo , . . 
Published: April 2019

Background/Objectives: This study aims to investigate whether materialism tendency will act as a moderating variable for the inaction inertia phenomenon.Methods/Statistical analysis: A total of 121 college students were randomly assigned to 2 (difference in attractiveness condition: large vs. small) Ã— 2 (materialism: high vs. low) mixed design. Respondents read two-part scenario and responded to several questions: manipulation check item to assess perceived attractiveness, some questions related to regret (immediate regret, recalled experienced regret, anticipated inaction regret, anticipated action regret), behavioral intention, and demographics.Findings: First, the manipulation of the perception of difference in attractiveness (manipulated with price difference) was as the researcher intended. Immediate regret after missing the initial opportunity, recalled experienced regret, and anticipated action regret were found to be varied on the level of materialism. The level of recalled experienced regret, anticipated action regret, and anticipated inaction regret varied according to the difference in attractiveness conditions. The interaction effects of the level of materialism and difference in attractiveness conditions appeared only for anticipated action regret and anticipated inaction regret. Anticipated action regret and inaction regret were found to have a significant effect on behavioral intention regardless of the level of materialism. On the other hand, recalled experienced regret had a significant impact on behavioral intention only in low-materialist group.Improvements/Applications: This study has theoretical and practical implications from the point of view of how the various kinds of regrets vary according to materialism in the area of inaction inertia effect.Â Â

Published: April 2019

Background/Objectives: This study aimed to investigate and complement the ways of improving the Technological Pedagogical Content Knowledge-Programming (TPACK-P) educational program and verify the improved programâ€™s effect on pre-service teachersâ€™TPACK.Methods/Statistical Analysis: The TPACK-P educational program was conducted for 19 pre-service teachers; two difficulty items were investigated. A survey was administered to identify any improvement. To verify the effect of the improved program on the pre-service teachersâ€™ TPACK, two programs involving distinct technological tools were applied to the control and experimental groups. To generate comparable results, the same research procedure was adopted as in a previous study, with some modifications.Findings: The pre-service teachers had difficulties in the process of learning programming, designing lessons, and developing programs in the TPACK-P educational program. In addition, they needed increased time for learning programming and analyzing the activities in the TPACK-P class. Therefore, the improved TPACK-P educational program added programming-based activities (analysis of curriculum based on programming, analysis of TPACK-P instructional cases, and development of the TPACK-P program in the programming environment). As a result of engaging the pre-service teachers in the improved TPACK-P educational program, the pre-service teachersâ€™ TPACK was effectively developed in all areas. Moreover, it was found to be more effective in improving the knowledge of technology than information and communication technology (ICT)-based TPACK educational program was.Improvements/Applications: This study can be used as a basic foundation for carrying out programming-based TPACK education for pre-service teachers.Â Â
Some Contributions to Boolean like near Rings
Authors: Pushpalatha K , . . 
Published: April 2019

In this paper we extend Fosterâ€™s Boolean-like ring to Near-rings. We introduce the concept of a Boolean like near-ring.Â A near-ring N is said to be a Boolean-like near-ring if the following conditions hold: (i) a+a = 0 for allÂ Â aÃŽ N , (ii) ab(a+b+ab) = ba for all a, bÂ ÃŽ N and (iii) abc = acb for all a,b, c ÃŽ N (right weak commutative law).Â We have proved that every Boolean ringÂ is a Boolean like near-ring. An example is given to show that the converse is not true.Â We prove thatÂ if N is a Boolean near-ring then conditions (i) and (ii) of the above definition are equivalent. We also proved that a Boolean near-ring with condition (iii) is a Boolean ring. As a consequence we show that a Boolean â€“like near-ring N is a Boolean ring if and only if it is a Boolean near-ring. Obviously, every Boolean like ring is a Boolean like near-ring. Â Â We show that Â if N is a Boolean-like near-ring with identity, then N is a Boolean-like ring.Â In addition we prove several interesting properties of Â Â Boolean-like near-rings. Â We prove that the set of all nilpotent elements of a Boolean â€“like near-ring N forms an ideal and the quotient near-ring N/I is a Boolean ring. Every homomorphic image of a Boolean like near ring is a Boolean like near ring.Â Â We further prove that every Boolean-like near-ring is a Boolean-like semiring Â Â As example is given to show that the converse of this result is not true.

An investigation is made for analyzing the behavior of MHD flow phenomena of a non-Newtonian fluid over a non-linear radially stretching sheet by using numerical technique. Magnetic field is considered in normal direction to the stretching sheet. With use of similarity transformations, the pdes are transformed into odes. The solution of theses odes are performed by using fourth order Runge - Kutta method along with shooting technique. The significance of different physical parameters characterizes the flow phenomena are analyzed with the use of graphs. The Jeffrey parameter and magnetic parameter has significant effect on velocity and temperature distribution over a non-linear stretching sheet. It is noticed that, the higher magnetic parameter results the increase in entropy generation number where the opposite nature is noticed in the case of Bejan number.

Published: April 2019

This paper primarily aims to provide a systematic review of factors influencing the individuals’ acceptance of Internet of things (IoT). There are numerous studies in literature that examine factors affecting technology acceptance. However, the studies on the review for acceptance of Internet of Things is limited. This study conducted a review and analysis of 32 articles from academic journals and conference proceedings published about the adoption, acceptance and diffusion of IoT. According to the review outcome, there are increasing numbers of studies that have been conducted in the IoT acceptance among individuals hailing from various points of view, with different factors affecting such viewpoints. Nevertheless, it was also noted that a theoretical, methodological and empirical study has yet to be carried out in the field to determine the factors related to the context of its application. The findings also led the author to recommend more future theoretical, methodological and empirical research to be conducted on the topic.

Published: April 2019

Escherichia coli is a group of Enterobacteriaceae bacteria that often contaminate food so that it can cause diarrhea. These bacteria are very difficult to treat if they are able to produce the Extended-Spectrum Beta-Lactamases (ESBLs) enzyme. The purpose of this study was to identify ESBLs-producing E. coli in food samples in Krian Sidoarjo. Food samples (fried foods, cilok tempura and chili sauce) were collected from ten different places. The sample was then grown on Eosin Methylene Blue (EMB) medium and purified by the 16 streak method, as well as biochemical character tests. The ESBLs phenotypic E. coli method was carried out by screening test and confirmation test using a Double Disk Synergy Test (DDST). Thirty colonies were able to grow on EMB media, but after microscopic identification and biochemistry testing only four samples were E. coli positive and were able to produce ESBLs from the phenotypic test that had been carried out. ESBLs-producing E. coli testing is important not only for nosocomial infections but also for the community so it needs attention to the spread of ESBLs resistance among microorganism species.

Escherichia coli termasuk kelompok bakteri Enterobacteriaceae yang sering mengkontaminasi makanan sehingga dapat menyebabkan diare. Bakteri ini sangat sulit diobati apabila mampu memproduksi enzim Extended Spectrum Beta-Lactamases (ESBLs). Tujuan penelitian ini adalah untuk mengindetifikasi E. coli penghasil ESBLs pada sampel makanan di Krian Sidoarjo. Sampel makanan (gorengan, cilok, tempura, dan saus sambal) dikumpulkan dari sepuluh tempat berbeda. Sampel kemudian ditumbuhkan pada medium Eosin Metilen Blue (EMB) dan dimurnikan dengan metode streak 16, serta dilakukan karakteristik uji biokimia. Metode fenotipik E. coli penghasil ESBLs dilakukan dengan uji skrining dan uji konfirmasi menggunakan double disk synergy test (DDST). Sebanyak tiga puluh koloni mampu tumbuh pada media EMB, namun setelah diidentifikasi mikroskopis dan uji biokiomia hanya empat sampel positif E. coli dan mampu menghasilkan ESBLs dari uji fenotipik yang telah dilakukan. Pengujian E. coli penghasil ESBLs penting dilakukan bukan hanya pada infeksi nosokomial, tetapi juga pada komunitas sehingga perlu mendapat perhatian terhadap penyebaran resistensi ESBLs diantara spesies mikroorganisme.

The BBC Charter Review
Authors: Barr Trevor 
Published: April 2019

Both the British Broadcasting Corporation (BBC) and the Australian Broadcasting Corporation (ABC) are being subjected to close scrutiny, but from different quarters. During the lead up to the British general election in 2015, the Cameron Conservative government issued a Green Paper, BBC Charter Review, July-October 2015, which broke new ground in terms of the scope of such an enquiry for its level of institutional criticism. Whilst ostensibly the document only purported to raise options for future change, and invited public submissions for consideration, there has been widespread concern about the possible serious intentions of the government for the corporation’s future. Though the ABC appears to be subject to much less vitriolic attack than its British counterpart, it too faces a range of threats and abuses. Paradoxically, such aggressive scrutiny comes at a time when both broadcasting corporations enjoy record audiences, continuing high levels of public trust, and on-line market leadership as a result their successful development of new digital platforms.
Consumer social responsibility
Authors: Michalski Michał A. 
Published: April 2019

In our contemporary literature and academic discourse, we often see how popular the topic of corporate social responsibility is. It will be argued that another problem, tightly linked to this issue, and strongly influencing the business environment is the consumer behaviour. This second part of business relations is often associated rather with legal demands and customer protection. The purpose of my article is to show how consumer social responsibility can help not only the corporations but also those involved in the market exchange to contribute to the common good and improve quality of millions of transactions people make every day. To become real, this responsibility needs effort—courage to witness by expressing consumer’s opinion and education. The first aspect shows how important action is in revealing values and introducing ethics into everyday market activity, the second shows that emphasizing basic economic education and expecting thorough information from companies can help build and enhance consumer awareness. This article also attempts to demonstrate the contributions of Catholic Social Thought to the problem of social responsibility.
Increased Failure After Irrigation and Debridement for Acute Hematogenous Periprosthetic Joint Infection
Authors: Shohat Noam , Goswami Karan , Tan Timothy L. , Fillingham Yale , Parvizi Javad 
Published: April 2019

Background:
Acute periprosthetic joint infection (PJI) is difficult to treat. In this study, we investigated the failure rates of irrigation and debridement (I&D) among patients with acute post-surgical and acute hematogenous PJI, and explored various host and organism-related risk factors that may be associated with treatment failure.

Methods:
We retrospectively reviewed the cases of 199 total joint arthroplasty patients who underwent I&D for acute post-surgical PJI (<3 months postoperatively) and acute hematogenous PJI (≥3 months postoperatively, with abrupt symptoms lasting <3 weeks) at a single center during the period of 2005 to 2016. Only patients meeting the Musculoskeletal Infection Society (MSIS) criteria for PJI were included. Patient demographics, comorbidities, physical examination findings, laboratory results, and organism profile were identified. Treatment failure, as defined by the Delphi criteria, was determined for 1-year follow-up. Primary statistical analysis involved univariate and multivariate regression.

Results:
The failure rate was 37.7% (75 of 199) at 1 year. Among the patients with acute hematogenous infections, the rate of failure (56%, 29 of 52) was almost 2 times higher than that of patients with acute post-surgical infections (31%, 46 of 147) (adjusted odds ratio [OR], 2.36; 95% confidence interval [CI], 1.16 to 4.81; p = 0.018). Host predictors of failure included prior revision surgery (adjusted OR, 2.55; 95% CI, 1.22 to 5.32; p = 0.013) and a higher Charlson Comorbidity Index (adjusted OR, 1.22; 95% CI, 1.01 to 1.51; p = 0.048). Specific comorbidities associated with failure included chronic obstructive pulmonary disease (p = 0.026), diabetes (p = 0.004), and a history of malignancy (p = 0.005). Patients with polymicrobial infections (adjusted OR, 2.40; 95% CI, 1.10 to 5.20; p = 0.028) were also more likely to experience failure of treatment after I&D. The clinical and laboratory risk factors associated with failure were the presence of intraoperative purulence (p = 0.05), elevated systolic blood pressure (p = 0.05), tachycardia (p = 0.06), and higher serum C-reactive protein level (p = 0.003).

Conclusions:
This study revealed that I&D is associated with a high rate of failure for patients with an acute hematogenous PJI. The study also identified a number of risk factors for failure. The findings of this study may allow better decision-making by surgeons regarding the surgical management of patients with acute PJI.
