Environmentally Benign PEG-OSO3H-Catalysed Ultrasound Promoted Cascade Synthesis of Furocoumarins in Water
Authors: Wagare Devendra , Shaikh Mujahed , Lingampalle Dinesh , Durrani Ayesha 
Published: July 2020

Background:
For the green synthesis of furocoumarins in water, PEG-OSO3H was used as a
recyclable catalyst for the one-pot synthesis in water. To avoid the use of toxic lachrymators and unstable
phenacyl bromides, we prepared them in-situ and directly condensed with 4-hydroxycoumarins.

Objective:
PEG-OSO3H was found to be an efficient and reusable catalyst for the microwave irradiated
one-pot synthesis of 3-Aryl-furo[3,2-c]coumarins in PEG-water as a greener reaction medium. This
method was found to be rapid, simple, eco-friendly and obtained relatively higher yield than other reported
methods.

Methods:
Aromatic ketones (5 mmol), NBS (5mmol) were added in the solution of PEG-OSO3H (10
mol%) in 10 ml water and irradiated under ultrasound at 80-85°C. Then, the solution of 4-
hydroxycoumarin (5 mmol) and the solution of acetic acid and ammonium acetate (1 ml) were added
into it. The reaction mass was further irradiated for 3 min. From the reaction mixture, ethyl acetate (3 x
10ml) was extracted and the combined ethyl acetate phase was concentrated under reduced pressure to
obtain corresponding 3-Aryl-furo[3,2-c]coumarins. The aqueous layer was reused for the next reactions.

Results:
It was observed that electrons withdrawing groups (-NO2,-F etc.) on the benzene ring of aromatic
ketones increased the rate of reactions as well as the yield of the products. The IR spectrum of
compound 4a showed prominent peaks at 1737cm-1C=O stretching for lactone. 1H NMR of compound
4c showed characteristic singlets for –CH3 of methoxy group at 3.94 ppm. The above spectral data
confirmed the structure of the compound. The 13C NMR spectrum of 4b also showed the peaks of
CH3, at 23.25 ppm.

Conclusion:
PEG-OSO3H has been found to be an efficient and reusable catalyst for the microwave
irradiated one-pot synthesis of 3-Aryl-furo[3,2-c]coumarins in PEG-water as a greener reaction medium.
This method found to be rapid, simple, eco-friendly and obtained relatively higher yield than other
reported methods.

Published: July 2020

Mental health issues have many causes, including the changing and unpredictable elements of the urban physical setting. Thus, this research is crucial to understand the mental health challenges of the urban population in Malaysia. Therefore, the objective of this research is to assess the magnitude of mental health outcomes and associated factors of the urban physical setting among the urban population. A study was carried out at two low-cost flats in Lembah Pantai, Kuala Lumpur, with a sample size of 102 respondents. The findings show that there is a correlation between the urban physical environment setting, particularly green spaces with mental disorders (depression, anxiety, and stress).

Intention to use Medical Apps Among Older Adults in the Netherlands: Cross-Sectional Study
Authors: Askari Marjan , Klaver Nicky Sabine , van Gestel Thimon Johannes , van de Klundert Joris 
Published: July 2020

Background
The increasing health service demand driven by the aging of the global population calls for the development of modes of health service delivery that are less human resource–intensive. Electronic health (eHealth) and medical apps are expected to play an important role in this development. Although evidence shows mobile medical apps might be effective in improving the care, self-management, self-efficacy, health-related behavior, and medication adherence of older adults, little is known about older adults’ intention to use these technologies when needed, or the factors influencing this intention.

Objective
The objective of this study was to investigate the relationship of technology acceptance factors and intention to use mobile medical apps among community-dwelling older adults.

Methods
Data was collected using questionnaires. The factors selected from the literature have been validated using Cronbach α and tested for significance using logistic regressions.

Results
Almost half (49.7%) of the included older adults reported no intention to use medical apps. Adjusted logistic regression analysis per factor showed that the factors Attitude toward use (odds ratio [OR] 8.50), Perceived usefulness (OR 5.25), Perceived ease of use (OR 4.22), Service availability (OR 3.46), Sense of control (OR 3.40), Self-perceived effectiveness (OR 2.69), Facilities (OR 2.45), Personal innovativeness (OR 2.08), Social relationships (OR 1.79), Subjective norm (OR 1.48), and Feelings of anxiety (OR 0.62) significantly influenced the intention to use mobile medical apps among older adults, whereas the factor Finance (OR 0.98) did not. When considered together, a controlled multivariate logistic regression yielded high explained variances of 0.542 (Cox-Snell R2) and 0.728 (Nagelkerke R2).

Conclusions
The high odds ratios and explained variance indicate that the factors associated with the intention to use medical apps are largely understood and the most important factors have been identified. To advance the evidence base, experimental controlled research should investigate the causality between the factors, intention to use, and actual use. For this purpose, our evidence suggests that policies designed to improve Attitude toward use appear most effective, followed by policies addressing Perceived usefulness, Perceived ease of use, Service availability, and Sense of control.

Published: July 2020

Produksi minyak kayuputih dari Kepulauan Maluku dan Pulau Jawa saat ini masih jauh di bawah permintaan kayuputih dalam negeri. Ekstensifikasi perkebunan kayuputih skala kecil yang dikelola oleh masyarakat dengan menggunakan benih unggul dapat menjadi solusi untuk meningkatakan produksi minyak kayuputih di Indonesia. Tulisan ini dimaksudkan untuk mengetahui tingkat kelayakan finansial dari usaha perkebunan kayuputih skala kecil dengan menggunakan data dari pilot project pengembangan industri kayuputih skala kecil di Kampung Rimbajaya, Distrik Biak Timur seluas 5 ha. Kelayakan finansial dilihat dari kriteria investasi yang umum digunakan yaitu net present value (NPV), internal rate of return (IRR), benefit-cost ratio (BCR) dan payback period. Hasil analisis finansial menunjukkan bahwa kebun kayuputih unggul skala kecil layak untuk diusahakan dengan NPV untuk jangka waktu 25 tahun pada discount rate 9,2% adalah sebesar Rp 757.171.972,00 (Rp 151.434.394,32 per hektar), IRR sebesar 72,74%, BCR sebesar 1,77 dan payback period setelah 2 tahun 3 bulan. Secara finansial perkebunan kayuputih yang menggunakan benih unggul lebih layak diusahakan dibandingkan dengan komoditas bambu, sengon, sawit dan kopi. Financial Analysis of a Small Scale Cajuput Plantation: A Case Study of A Pilot Project for A Farmer Group in Rimbajaya Village, East Biak DistrictAbstractProduction of cajuput oil from the Moluccas and Java Island is currently far below the domestic demand for the oil. Extensification of small-scale cajuput plantations managed by community using improved seeds is expected to increase cajuput oil production inIndonesia. This study investigates the financial feasibility of a 5 ha-cajuput plantation using data collected from a pilot project for a farmer group in Rimbajaya Village, East Biak District. Financial feasibility was assessed by calculating four investment criteria: netpresent value (NPV), internal rate of return (IRR), benefit-cost ratio (BCR) and payback period. The analysis showed that a small-scale cajuput plantation was financially feasible with NPV (25 years) at a 9.2% discount rate was IDR 687,583,363.00 (IDR 137,516,672.63 per hectare), IRR of 66.5%, BCR of 1.70 and payback period after 2 years and 3 months. Investation in a cajuput plantation planted with improved seeds is more feasible than that in bamboo, sengon, palm oil and coffee plantations.

Deforestasi atau perubahan fungsi dari hutan menjadi non-hutan berperan dalam perubahan ekosistem dan spesies di dalamnya. Serangga sebagai salah satu fauna di dalamnya merupakan aspek yang menarik untuk dikaji khususnya semut. Tujuan penelitian ini adalah mengidentifikasi peranan-peranan dari genus semut yang ditemukan di ekosistem transformasi. Penelitian dilaksanakan di Desa Bungku, Kecamatan Bajubang, Kabupaten Batanghari, Provinsi Jambi. Metode yang digunakan dalam penelitian ini adalah membuat plot pengamatan secara purposive sampling. Plot pengamatan dipasang di empat eksosistem hutan dengan jumlah masing - masing ekosistem sebanyak empat plot. Setiap plot memiliki lima sub plot yang tersebar di empat eksosistem hutan untuk pemasangan pitfall trap. Teknik pengambilan sampel semut menggunakan pitfall trap di empat ekosistem. Empat ekosistem tersebut yaitu hutan sekunder, perkebunan kelapa sawit, kebun karet, dan hutan karet. Hasil penelitian ditemukan sebanyak 33 genus dari 6 subfamili. Selanjutnya dari 33 genus dikelompokkan berdasarkan peranannya. Berdasarkan peranannya terdapat 46% pencari makan , 36% predator, 3% semut tentara, 3% pemakan bangkai, dan 3% lainnya (semut pemanen/pemetik, omnivora, predator, dan pemakan bangkai). Camponotus sebagai genus dominan memiliki peranan pencari makan, dan Pheidole mempunyai peranan sebagai penghancur biji dan sebagian lainnya adalah omnivora.

Authors: Lalancette Mireille , Small Tamara A. 
Published: July 2020

Background An internet meme is a concept or idea that spreads online. This article focuses on memes chronicling Justin Trudeau’s leadership during his first year as prime minister. Analysis By conceptualizing leadership memes and developing a methodology to analyze these memes, this empirical study reflects the approaches meme creators use, both visually and rhetorically, to convey political messages about leadership. Conclusion and implications The main purpose of Justin Trudeau memes is denunciation. Leadership memes present an alternative discourse of politics, outside of controlled channels of the politician and the traditional media. There is little work on leadership memes. This article contributes to the literature by not only focusing on Canadian politics but also by providing a method for studying leadership memes.
Enabling Postmedia: Economists as the “Rock Stars” of Canadian Competition Law
Authors: Edge Marc 
Published: July 2020

Background Canada is suffering a crisis in local news largely attributable to regulatory failure. Its largest newspaper chain, Postmedia Network, took over the second-largest chain in late 2014, and in early 2016 it merged the newsrooms at its duplicate dailies in four of Canada’s six largest cities. Parliamentary hearings on local media ensued, and a mid-2017 report recommended, among other things, changes to the Competition Actto more effectively deal with news media mergers and takeovers. Analysis The Competition Bureau is dominated by economists who may lack sufficient grounding in media issues to effectively deal with mergers and takeovers in news industries. Conclusion and implications Reform of the country’s Competition Act, which has been called for by successive federal media inquiries, is more urgently required than ever.

GÊNERO E PRODUÇÃO DE PRESENÇA HOMOERÓTICA NA CONSTRUÇÃO DO MASCULINO EM MORTE EM VENEZA, DE THOMAS MANN
Authors: Bellin Greicy Pinto , Gomes Jonhes Tadeu 
Published: July 2020

Este artigo pretende analisar as relações entre homoerotismo, ambiência e Stimmung na construção do masculino na novela Morte em Veneza, de Thomas Mann (1911). Pretende-se trabalhar com os conceitos de gênero e performance propostos por Joan Scott, Teresa de Lauretis e Judith Butler, respectivamente, relacionando-as aos conceitos desenvolvidos por Hans Ulrich Gumbrecht em Atmosfera, ambiência e Stimmung (2014). Nosso objetivo é compreender o papel desempenhado pelas construções de gênero na representação de um homoerotismo construído por meio de elementos materiais do texto relacionados à ambiência da narrativa, e por meio de elementos da mitologia grega, perceptíveis no texto de Thomas Mann.

REPRESENTAÇÕES E PRÁTICAS EM "TERRAS DO SEM-FIM", DE JORGE AMADO: A NEGOCIAÇÃO COM O MUNDO SOCIAL
Authors: Badaró Santos José Otávio Monteiro , Moreira Marcello 
Published: July 2020

A proposta é analisar o romance Terras do sem-fim (1943), de Jorge Amado, em uma perspectiva da literatura como representação, na esteira dos estudos de Louis Marin e Roger Chartier, considerando o texto como a representação das sensibilidades de determinados homens, em dada época, da ideia que faziam de sua própria sociedade e dos significados que almejavam construir. Assim, pretendemos refutar a ideia de que a obra, circunscrita pela crítica marxista como romance proletário, seja uma homologia das estruturas sociais. A noção de representação nos permite compreender que os textos ficcionais são, na verdade, constituídos pela relação que estabelecem com outros discursos e não com a realidade empírica.
