USE OF GAS TURBINES FOR COMBINED ENERGY PRODUCTION
Authors: Bulanin V. A.
Published: April 2020

Abstract. Aim. Despite the obvious expediency of their widespread implementation, gas turbine (GT) and combined cycle gas turbine (CCGT) plants were only used in limited quantities in the former USSR and CIS countries. Due to the exhaustion of possibilities to increase the fuel use efficiency and return on investment (ROI) in steam-turbine combined heat and power (CHP) plants, the development of GT and CCGT plants becomes an urgent problem. In current global practice, the primary fuel for gas turbines and combined cycle gas turbines is natural gas. However, until recently, there has been a lack of experience in the design, construction and operation of GT and CCGT plants in the CIS countries.

Method. Due to the ad hoc nature of research in this area, it was necessary to systematise the results of existing studies and assess the state of research at the world level taking regional characteristics into account.

Results. The article presents the main considerations and potential effectiveness of the use of gas turbines. Basic gas turbine construction schemes are investigated along with their techno-economic characteristics and an assessment of their comparative utility.

Conclusion. Considering the widespread availability of natural gas, it is recommended that gas turbine and combined-cycle plants be installed as part of the process of technical re-equipment in the fuel and energy complex, industry, agriculture and municipal energy sectors as part of the design and construction of new energy sources in the light of positive world experience and the current level of development of gas turbine technologies. Ubiquitous implementation of gas turbine units in the centres supplying heat and electric loads will reduce the regional economy’s need for energy fuel and ensure an increase in energy capacity without the need to construct new complex and uneconomic steam turbine power plants.

When testing on a rocket track, one of the most difficult problems is the system for controlling and launching pyrotechnic devices at a given coordinate. The way of start-up and device for its implementation, is intended to provide actuation of pyrotechnic means during acceleration of the rocket trains on the rails rocket catapult track to hypersonic speeds with ejection test subject in free flight. The method is based on the principle of generating current pulses for triggering pyrotechnic devices of moving stages of a rocket train using induction sensors. The same principle makes it possible to implement a non-contact method for starting recording systems and a device for measuring the average speed of a thrown object in continuous media. The method is based on the principle of generating triggering signals (rectangular pulses of positive polarity) for starting the recording equipment with synchronization of the launch along the path in a given coordinate and measuring the speed of the object being thrown at the time of its passage through the measuring section. The methods of starting recording systems and the results obtained as a result of hydrodynamic and terradynamic experiments are presented.

The possibilities of the control of stability limit location were experimentally investigated in spherical Couette flow. The inner sphere rotational rate is periodically varied about non-zero average value, the outer sphere is fixed. Instability in the form of travelling azimuthal waves, the same as at stationary rotation, is caused by increasing of average rotational rate. Flow velocity measurements were carried out by laser Doppler anemometer. It was shown, that when modulation frequency become close to eigenfrequency of linear mode, both flow destabilization and stabilization were possible depending on modulation amplitude.

On the example of n-pentane superheated on 81 K with respect to the liquid-vapor equilibrium temperature, the possibility of local activation of liquid boiling-up by a laser pulse at the end of a single-mode fiber is shown. An activation threshold for the radiation intensity at the end of the fiber has been revealed. The activation threshold value depends on the state of the fiber end, and the boiling-up processes are likely to develop at the interface. Like a spontaneous boiling-up process, a stepwise propagating change in the refractive index of the liquid is observed in the course of activation. The conclusion is drawn about the uniformity of the recorded processes at spontaneous and activated boiling-up of n-pentane.
A Comparison of the Psycholinguistic Styles of Schizophrenia-Related Stigma and Depression-Related Stigma on Social Media: Content Analysis
Authors: Li Ang , Jiao Dongdong , Liu Xiaoqian , Zhu Tingshao
Published: April 2020

Background

Stigma related to schizophrenia is considered to be the primary focus of antistigma campaigns. Accurate and efficient detection of stigma toward schizophrenia in mass media is essential for the development of targeted antistigma interventions at the population level.

Objective

The purpose of this study was to examine the psycholinguistic characteristics of schizophrenia-related stigma on social media (ie, Sina Weibo, a Chinese microblogging website), and then to explore whether schizophrenia-related stigma can be distinguished from stigma toward other mental illnesses (ie, depression-related stigma) in terms of psycholinguistic style.

Methods

A total of 19,224 schizophrenia- and 15,879 depression-related Weibo posts were collected and analyzed. First, a human-based content analysis was performed on collected posts to determine whether they reflected stigma or not. Second, by using Linguistic Inquiry and Word Count software (Simplified Chinese version), a number of psycholinguistic features were automatically extracted from each post. Third, based on selected key features, four groups of classification models were established for different purposes: (a) differentiating schizophrenia-related stigma from nonstigma, (b) differentiating a certain subcategory of schizophrenia-related stigma from other subcategories, (c) differentiating schizophrenia-related stigma from depression-related stigma, and (d) differentiating a certain subcategory of schizophrenia-related stigma from the corresponding subcategory of depression-related stigma.

Results

In total, 26.22% of schizophrenia-related posts were labeled as stigmatizing posts. The proportion of posts indicating depression-related stigma was significantly lower than that indicating schizophrenia-related stigma (χ21=2484.64, P<.001). The classification performance of the models in the four groups ranged from .71 to .92 (F measure).

Conclusions

The findings of this study have implications for the detection and reduction of stigma toward schizophrenia on social media.

Authors: Ndwandwe Duduzile , Ngcobo Ntombenhle J , Adamu Abdu A , Nnaji Chukwudi , Mashunye Thandiwe , Leufak Arlette M , Cooper Sara , Uthman Olalekan A , Wiysonge Charles S
Published: April 2020

Background

Vaccination is one of the greatest public health interventions of all time. Vaccination coverage in South Africa has shown a steady improvement in reaching the national target. However, while there is progress nationally, there are districts within the country that are below the set target for vaccination coverage. One of the main drivers of suboptimal vaccination coverage is thought to be missed opportunities for vaccination.

Objective

This study aims to understand the magnitude and determinants of missed opportunities for vaccination in South Africa.

Methods

The 2016 South African Demographic and Health Survey will be used to conduct multilevel regression analyses to determine individual and contextual factors associated with missed opportunities for vaccination in South Africa. The perspectives of parents attending health care facilities in South Africa will be explored through exit interviews and focus group discussions. Similarly, perspectives of the health care providers will be sought to understand enablers and barriers to vaccination coverage at the facility level. Insights to such factors will aid in designing tailor-made interventions to improve vaccination coverage in South Africa.

Results

Ethical review submission is planned for October 2020. Data collection is expected to be underway in January 2021.

Conclusions

The extent of missed opportunities in South Africa coupled with the associated factors presents an opportunity for efforts to increase uptake in districts where vaccination coverage is below the national target. Population-level data such as those from the 2016 South African Demographic Health Survey will provide an idea of the magnitude of missed opportunities for vaccination in South Africa at the national and subnational levels. The findings of the study will inform national and subnational policy implementation on vaccinations and help to find context-specific interventions to improve vaccination coverage.

Authors: Jiang Yuyu , Liu Fenglan , Guo Jianlan , Sun Pingping , Chen Zhongyi , Li Jinping , Cai Liming , Zhao Hongqing , Gao Ping , Ding Zhaosheng , Wu Xiaoliang
Published: April 2020

BACKGROUND

The application of telemedicine in home pulmonary rehabilitation interventions for the management of patients with chronic obstructive pulmonary disease (COPD) has achieved promising results.

OBJECTIVE

This study aimed to develop a WeChat official account (Pulmonary Internet Explorer Rehabilitation [PeR]) based on social media. It further evaluated the effect of PeR on the quality of life, symptoms, and exercise self-efficacy of patients with COPD.

METHODS

The functional modules of PeR were developed by a multidisciplinary team according to the electronic health–enhanced chronic care model (eCCM) components. A total of 106 patients were randomly selected (53 in the PeR group and 53 in the outpatient face-to-face group [FtF]). Pulmonary rehabilitation intervention was conducted for 3 months, and the outcome was observed for 3 months. The primary outcome was patient quality of life measured with the COPD assessment test (CAT). The secondary outcomes were evaluated using the modified Medical Research Council scale (mMRC), exercise self-regulatory efficacy scale (Ex-SRES), and St George’s Respiratory Questionnaire (SGRQ).

RESULTS

The intention-to-treat analysis was used in the study. A total of 94 participants completed the 6-month pulmonary rehabilitation program. No statistically significant differences were observed in CAT (F1,3=7.78, P=.001), Ex-SRES (F1,3=21.91, P<.001), and mMRC scores (F1,3=29.64, P<.001) between the two groups with the variation in time tendency. The Ex-SRES score had a significant effect on the CAT score (P=.03). The partial regression coefficient of Ex-SRES to CAT was 0.81, and Exp (B) was 2.24.

CONCLUSIONS

The telemedicine technology was effective using the eCCM combined with a behavioral intervention strategy centering on self-efficacy. Pulmonary rehabilitation at home through PeR and FtF could improve the sense of self-efficacy and quality of life and alleviate symptoms in patients with COPD.

Data Mining and Content Analysis of the Chinese Social Media Platform Weibo During the Early COVID-19 Outbreak: Retrospective Observational Infoveillance Study (Preprint)
Authors: Li Jiawei , Xu Qing , Cuomo Raphael , Purushothaman Vidya , Mackey Tim
Published: April 2020

BACKGROUND

The coronavirus disease (COVID-19) pandemic, which began in Wuhan, China in December 2019, is rapidly spreading worldwide with over 1.9 million cases as of mid-April 2020. Infoveillance approaches using social media can help characterize disease distribution and public knowledge, attitudes, and behaviors critical to the early stages of an outbreak.

OBJECTIVE

The aim of this study is to conduct a quantitative and qualitative assessment of Chinese social media posts originating in Wuhan City on the Chinese microblogging platform Weibo during the early stages of the COVID-19 outbreak.

METHODS

Chinese-language messages from Wuhan were collected for 39 days between December 23, 2019, and January 30, 2020, on Weibo. For quantitative analysis, the total daily cases of COVID-19 in Wuhan were obtained from the Chinese National Health Commission, and a linear regression model was used to determine if Weibo COVID-19 posts were predictive of the number of cases reported. Qualitative content analysis and an inductive manual coding approach were used to identify parent classifications of news and user-generated COVID-19 topics.

RESULTS

A total of 115,299 Weibo posts were collected during the study time frame consisting of an average of 2956 posts per day (minimum 0, maximum 13,587). Quantitative analysis found a positive correlation between the number of Weibo posts and the number of reported cases from Wuhan, with approximately 10 more COVID-19 cases per 40 social media posts (P<.001). This effect size was also larger than what was observed for the rest of China excluding Hubei Province (where Wuhan is the capital city) and held when comparing the number of Weibo posts to the incidence proportion of cases in Hubei Province. Qualitative analysis of 11,893 posts during the first 21 days of the study period with COVID-19-related posts uncovered four parent classifications including Weibo discussions about the causative agent of the disease, changing epidemiological characteristics of the outbreak, public reaction to outbreak control and response measures, and other topics. Generally, these themes also exhibited public uncertainty and changing knowledge and attitudes about COVID-19, including posts exhibiting both protective and higher-risk behaviors.

CONCLUSIONS

The results of this study provide initial insight into the origins of the COVID-19 outbreak based on quantitative and qualitative analysis of Chinese social media data at the initial epicenter in Wuhan City. Future studies should continue to explore the utility of social media data to predict COVID-19 disease severity, measure public reaction and behavior, and evaluate effectiveness of outbreak communication.
Barriers and Enablers in Implementing Electronic Consultations in Primary Care: Scoping Review (Preprint)
Authors: Baines Rebecca , Tredinnick-Rowe John , Jones Ray , Chatterjee Arunangsu
Published: April 2020

BACKGROUND

Often promoted as a way to address increasing demands, improve patient accessibility, and improve overall efficiency, electronic consultations are becoming increasingly common in primary care, particularly in light of the current COVID-19 pandemic. However, despite their increasing use, a theoretically informed understanding of the factors that support and inhibit their effective implementation is severely limited.

OBJECTIVE

With this scoping review, we sought to identify the factors that support and inhibit the implementation of electronic consultations in primary care.

METHODS

In total, 5 electronic databases (PubMed, Medline, Embase, CINAHL, and PsycINFO) were systematically searched for studies published in 2009-2019 that explored the impact and/or implementation of electronic consultations in primary care. Database searches were supplemented by reference list and grey literature searches. Data were analyzed using inductive thematic analysis and synthesized using Normalization Process Theory (NPT).

RESULTS

In total, 227 articles were initially identified and 13 were included in this review. The main factors found to hinder implementation included awareness and expectations; low levels of engagement; perceived suitability for all patient groups, conditions, and demographics; cost; and other contextual factors. Reports of information technology reliability and clinical workload duplication (as opposed to reduction) also appeared detrimental. Conversely, the development of protocols and guidance; patient and staff education; strategic marketing; and patient and public involvement were all identified as beneficial in facilitating electronic consultation implementation.

CONCLUSIONS

This review highlights the need for proactive engagement with patients and staff to facilitate understanding and awareness, process optimization, and delivery of coherent training and education that maximizes impact and success. Although the necessity to use online methods during the COVID-19 pandemic may have accelerated awareness, concerns over workload duplication and inequality of access may remain. Future research should explore health inequalities in electronic consultations and their economic impacts from multiple perspectives (eg, patient, professional, and commissioner) to determine their potential value. Further work to identify the role of meaningful patient involvement in digital innovation, implementation, and evaluation is also required following the rapid digitization of health and social care.
Developing a Mobile App (iGAM) to Promote Gingival Health by Professional Monitoring of Dental Selfies: User-Centered Design Approach (Preprint)
Authors: Tobias Guy , Spanier Assaf B
Published: April 2020

BACKGROUND

Dental visits are unpleasant; sometimes, patients only seek treatment when they are in intolerable pain. Recently, the novel coronavirus (COVID-19) pandemic has highlighted the need for remote communication when patients and dentists cannot meet in person.
Gingivitis is very common and characterized by red, swollen, bleeding gums. Gingivitis heals within 10 days of professional care and with daily, thorough oral hygiene practices. If left untreated, however, its progress may lead to teeth becoming mobile or lost. Of the many medical apps currently available, none monitor gingivitis.

OBJECTIVE

This study aimed to present a characterization and development model of a mobile health (mHealth) app called iGAM, which focuses on periodontal health and improves the information flow between dentists and patients.

METHODS

A focus group discussed the potential of an app to monitor gingivitis, and 3 semistructured in-depth interviews were conducted on the use of apps for monitoring gum infections. We used a qualitative design process based on the Agile approach, which incorporated the following 5 steps: (1) user story, (2) use cases, (3) functional requirements, (4) nonfunctional requirements, and (5) Agile software development cycles. In a pilot study with 18 participants aged 18-45 years and with different levels of health literacy, participants were given a toothbrush, toothpaste, mouthwash, toothpicks, and dental floss. After installing iGAM, they were asked to photograph their gums weekly for 4 weeks.

RESULTS

All participants in the focus group believed in the potential of a mobile app to monitor gingivitis and reduce its severity. Concerns about security and privacy issues were discussed. From the interviews, 2 themes were derived: (1) “what's in it for me?” and (2) the need for a take-home message. The 5 cycles of development highlighted the importance of communication between dentists, app developers, and the pilot group. Qualitative analysis of the data from the pilot study showed difficulty with: (1) the camera, which was alleviated with the provision of mouth openers, and (2) the operation of the phone, which was alleviated by changing the app to be fully automated, with a weekly reminder and an instructions document. Final interviews showed satisfaction.

CONCLUSIONS

iGAM is the first mHealth app for monitoring gingivitis using self-photography. iGAM facilitates the information flow between dentists and patients between checkups and may be useful when face-to-face consultations are not possible (such as during the COVID-19 pandemic).

Published: April 2020

Adaptation of a psychological instrument is essential due to cultural difference and context. This study aimed to adapt the Gratitude Questionnaire-6 (GQ-6) in an Indonesian context. The initial steps included back-to-back translation, focus group discussion, expert judgements, and pilot study. From this procedure, five additional items were added to the original GC-6. The eleven final items were tested to 404 undergraduate students aged 18-24 years-old from several universities in Jakarta. The reliability test, the internal consistency, was examined by the Cronbach’s alpha coefficient, while the validity test, construct validity, was examined using exploratory factor analysis (EFA).  The result of analysis showed good validity and reliability (Cronbach’s alpha: 0.789). This study concluded that 11-item gratitude questionnaire consistently measured gratitude in adolescents based on two factors: appreciation to the constant  experience of life and appreciation towards individuals that take part in one’s life.
The Role of Sexual Self-Control as Moderator between Sexual Desire and Premarital Sexual Behaviors
Authors: Sari Chindy Kencana , Tondok Marselius Sampe , Muttaqin Darmawan
Published: April 2020

Sexual desire can be one of the antecedents for individual premarital sexual behavior. Otherwise, sexual self-control can prevent individuals from engaging premarital sexual behavior. This study aimed to examine the role of self-control in moderating the relationship between sexual desire and premarital sexual behavior. This study involved 209 emerging adults (18-25 years old) who were dating and not undergoing a long-distance relationship. The current study used Premarital Sexual Permissiveness measurement, dyadic sexual desire subscale from Sexual Desire Inventory-II, general sex-drive and stimulus-elicited sex-drive subscales from Perceived Sexual Control to measure premarital sexual behavior, sexual desire, and sexual self-control respectively. Results of regression analysis showed that sexual self-control did not moderate the relationship between sexual desire and kissing (∆R2 = 0.006, p > 0.05), as well as sexual desire and petting (∆R2 = 0.001, p > 0.05). However, self-control could be a moderator in the relationship between sexual desire and intercourse (∆R2 = 0.027, p < 0.01).

Published: April 2020

Parents of children with developmental disorders are prone to experiencing parenting stress. This study aimed to examine the validity and reliability of the parenting stress construct. A total of 125 mothers of children with autistic spectrum disorder were involved in this study. The results showed that parenting stress consists of three domains: parent, child, and parent-child interaction. This was proven through a validity test using exploratory and confirmatory analysis. The exploratory analysis indicated that the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy was 0.716, meeting the requirement value of above 0.5. Additionally, Bartlett's test of sphericity was significant (p <0.05). Based on the confirmatory analysis, the model was classified as fit with the index: X² (50, N = 125) = 71.98, p = 0.023, RMSEA = 0.060, GFI = 0.91; IFI = 0.94; CFI = 0.94; and RMSEA = 0.077; convergent validity values (λ> 0.5; and AVE values> 0.5); construct reliability values (CR = 0.846). Analysis of psychometric properties of parenting stress met the assumptions of good construct validity and reliability.

Published: April 2020

Food security and safety are central topics worth to be investigated by academicians and practitioners. Radio frequency identification (RFID) is more than a tool with wireless microchips for identification but a facilitator that increases the traceability of food products and better business model innovations. This paper reviews the literature of issues regarding RFID in the context of food supply chains (e.g. issues on the feasibility of RFID for better food traceability). We make a careful review of 13 papers published in 9 SSCI journals and conferences published from 2004 to 2016. Findings are discussed for offering suggestions that could improve the research streams and practices.

Authors: Meghwar Shanker Lal , Khaskheli Ghous Bux , Kumar Aneel
Published: April 2020

The construction industry is the largest manufacturing industry, which produces concrete and other related materials for construction of infrastructure around the world, after the food production industry. This industry requires a lot of natural resources like aggregates, limestone etc. to produce finished product such as concrete and cement. These natural resources are limited and have to deplete one day, so alternate to these resources are required. On the other hand, this industry produces a large amount of waste material that creates environmental pollution. Thus, recycling the waste as potential raw material and to produce a usable product is the need of present era for sustainable construction. This study presents the quantitative analysis of HSH (Human Scalp Hair) as fibers in cement concrete. This study aims to investigate the behaviour of concrete in terms of their mechanical properties when HSH are used as fibers. A detailed investigation on two types of concrete specimens i.e. cylindrical (150 mm diameter and 300 mm height) and prism (150 mm depth, width and 600 mm length) made with a different proportion of HSH as fibers and concrete mix ratios, was carried out. In this study, various proportions of HSH added in concrete that includes 0%, 1%, 2% and 3% by weight of OPC (Ordinary Portland Cement). All specimens were cast at two concrete mix ratios i.e. 1:2:4 and 1:1.5:3 with 0.50 W/C (Water-Cement Ratio). Moreover, specimens were tested in UTM (Universal Testing Machine) at 28 days curing age, for splitting tensile strength and flexural strength of concrete. It was observed from the experimental analysis that there is an improvement in mechanical properties of concrete at specific percentage of HSH and reduction of workability and density with increasing percentages of HSH.

Type 2 diabetes mellitus predicts outcome following acute myocardial infarction (AMI). Since underlying
mechanics are incompletely understood, we investigated left ventricular (LV) and
atrial (LA) pathophysiological changes and their prognostic implications using
cardiovascular magnetic resonance (CMR). Consecutive patients (n=1147, n=265 diabetic; n=882 non-diabetic)
underwent CMR 3 days after AMI. Analyses included LV ejection fraction (LVEF),
global longitudinal, circumferential and radial strains (GLS, GCS and GRS), LA
reservoir, conduit and booster pump strains, as well as infarct size, edema and
microvascular obstruction. Predefined endpoints were major adverse cardiovascular
events (MACE) within 12 months. Diabetic patients had impaired LA reservoir
(19.8 vs. 21.2%, p<0.01) and conduit strains (7.6 vs. 9.0%, p<0.01) but
not ventricular function or myocardial damage. They were at higher risk of MACE
than non-diabetic patients (10.2% vs. 5.8%, p<0.01) with most MACE occurring
in patients with LVEF≥35%. Whilst LVEF (p=0.045) and atrial reservoir strain
(p=0.024) were independent predictors of MACE in non-diabetic patients, GLS was
in diabetic patients (p=0.010). Considering patients with diabetes and LVEF≥35%
(n=237), GLS and LA reservoir strain below median were significantly associated
with MACE. In conclusion, in patients with diabetes, LA and LV longitudinal strain permit optimized
risk assessment early after reperfused AMI with incremental prognostic value
over and above LVEF.
Russian Expert and Official Geopolitical Narratives on the Arctic: Decoding Topical and Paradigmatic DNA
Authors: Godzimirski Jakub M. , Sergunin Alexander
Published: April 2020

This article examines current Russian expert and official narratives on the Arctic, situating them in the broader context of the debate on Russia’s role in the international system. Combining a critical geopolitics approach to the study of international relations with content analysis tools, we map how structural geopolitical changes in the wider region have shaped narratives on the Arctic in Russia today. Two types of Russian narratives on the Arctic are explored—the one put forward by members of the Russian expert community, and the one that emerges from official documents and statements by members of the Russian policymaking community. With the expert narratives, we pay particular attention to the Arctic topics featured and how they are informed by various mainstream approaches to the study of international relations (IR). In examining policy practitioners’ narrative approaches, we trace the overlaps and differences between these and the expert narratives. Current expert and official Russian narratives on the Arctic appear to be influenced mostly by neorealist and neoliberal ideas in IR, without substantial modifications after the 2014 conflict, thus showing relatively high ideational continuity.
Food Memories
Authors: Alibhai-Brown Yasmin
Published: April 2020

Alight cake summoned up in Proust the most profound meditations on lost time and mortality. He came to believe that ‘When nothing subsists of an old past, after the death of people, after the destruction of things, alone, frailer but more enduring, more persistent, more faithful, smell and taste remain for a long time, like souls remembering, waiting, hoping upon the ruins of all the rest’. Food holds memory; it also consoles, stirs emotions, arouses and can often communicate unspoken (and unspeakable) thoughts and acts. Way back in 1954, Alice B. Toklas, the lesbian lover of avant-garde writer Gertrude Stein, released in a cookbook the many flavours of their long life together in France. Replete with pleasure, the recipes are really about sex that couldn’t speak its name so had to be covered in pastry and rich sauces. Elizabeth David’s meticulous and evocative food writing, some think, was her way of dealing with a frenetic and ultimately sad love life.
Australias Culinary Coming Out
Authors: Robinson Richard
Published: April 2020

Once perceived as a colonial backwater shaped by convicts, bushmen, laconic working class, and ANZACs, Australia has now asserted itself as a nation with strong and admired cultural attributes; home to world-class cities, globally recognised personalities, citizens of growing sophistication and a range of admired cultural institutions. One intriguing observation is that this accumulation of cultural capital has been mobilised by Australia’s emerging reputation in the realms of food and drink. Is Australia’s cultural ‘coming out’ indebted to its contemporary food and beverage professionals? Australia’s European heritage, and consequent worldwide exposure, began in the late 18th century. Before European contact, Australia’s knowledge of the world beyond its seaboards was limited to visits by the Macassan Indonesians fishing for trepang, or sea cucumber. In 1788, under pressure to alleviate pressure on their groaning penal system, exacerbated by the loss of the American colonies in the previous decade, the British sent Arthur Phillip to Sydney Cove to establish the first permanent European settlement in Terra Australis. Within a few decades, penal colonies were founded in all the other current Australian states – in or near their capitals; Hobart, Melbourne, Adelaide, Brisbane and Perth. The military, free settlers and emancipated convicts brought with them their largely Anglo-Celtic heritage, habitus and culture – architecture, agricultural and later industrial economies, political, religious and social institutions, clothing, social mores and rituals, and of course food and drink. Many of these, arguably, were ill suited to the remote, sparse and harsh antipodean environment. Yet little changed and the tyranny of distance ensured that what change there was would be tediously slow.
Give a Dog a Bad Name, British cooking and its place on the culinary leader board
Authors: Campion Charles
Published: April 2020

Ask any American, particularly those who have not yet visited Europe, and they will tell you that French food is magnificent while British food is ghastly. Visitors from the other side of the Atlantic long to be as glam as Gene Kelly or Leslie Caron, and they long to be that American in Paris – or better still a rose-tinted version of that city where the weather is always perfect and the food is always ambrosial. Somewhere along the time line between the Battle of Agincourt and the present day, British cooking has ended up pigeon-holed as a culinary alsoran to the French and there’s a widely held, if erroneous, view that the food in Britain is very poor indeed. This assessment may have been valid for a few impoverished decades after the Second World War but when it comes to cooks and cooking, things change quickly and today’s reality is very different.

AbstractBatik Kauman is produced by the manufacturer at the Kauman Village, Batang. In this region there are only two producers of batik, Batik Rizky and Batik Rudi (Rudi's Batik). The strong Islamic atmosphere of the environment and the producers’s good islamic understanding, had no effect on the motives of batik production. This research proves that the motives of the 14 variants generated by Rizky Batik (“batik cap” and “batik tulis”) there are 4 characters of animals: peacock, spider, phoenix birds and snails. And, Batik Rudi that produces 37 variants, there is 1 fish motif. The visual appearance of the animals is not in the form of a naturalist but already distillation with isen as generally batik motives. As we know that Islam does not only regulate all the systems of worship and our life but also in art. Facts show that consumer tastes are the basic consideration of 2 producer to produce batik. Geographical location (the northern coastal area) formed character into a cosmopolitan society, loudly and openly, so Islam developed in the region is acculturative with local culture, that influences the nature of the production Batik Kauman.AbstrakBatik Kauman adalah batik yang diproduksi oleh para produsen di wilayah Kelurahan Kauman, Batang. Di wilayah itu hanya ada 2 produsen batik, yaitu Batik Rizky dan Batik Rudi (Rudi’s Batik). Kentalnya nuansa Islami di lingkungan tersebut dan pemahaman keislaman produsennya yang relatif baik tidak ada pengaruhnya pada motif-motif batik hasil produksinya. Terbukti bahwa dari 14 varian motif yang dihasilkan oleh Batik Rizky (batik cap dan batik tulis) terdapat 4 karakter binatang yaitu merak,laba-laba, burung phoenix dan bekicot. Sedangkan pada Batik Rudi yang memproduksi batik cap sebanyak 37 varian motif, terdapat 1 motif ikan. Tampilan binatang tersebut tidak dalam bentuk naturalis tetapi sudah distilasi dengan isen-isen sebagaimana umumnya motif pada batik. Sebagaimana diketahui bahwa Islam tidak hanya mengatur segala sistem ibadah dan kehidupan kita tetapi juga dalam urusannya dengan kesenirupaan. Fakta yang terjadi bahwa selera konsumen menjadi dasar pertimbangan produksi 2 produsen batik tersebut. Letak geografis (Pantura) membentuk watak masyarakatnya menjadi kosmopolitan, keras dan terbuka sehingga Islam berkembang di wilayah tersebut sangat akulturatif dengan budaya lokal, dan hal ini ternyata berpengaruh pada karakter hasil produksi Batik Kauman
