Irrigation Development as an Instrument for Economic Growth in Saskatchewan: An Economic Impact Analysis
Allocation decisions in Saskatchewan of water are needed because of the limited nature of the resource in the province. Timely allocation of water can impact crop production, and through that economic development in the province, which may result through the value of the improved crop production as well as the economic linkages within the economy. Irrigation can be seen as a tool for economic growth as it decreases the reliance on natural factors which are critical for crop production in the province. The provincial government has committed, among its various agricultural initiatives, to develop tools to reach economic development goals. A study of the economic importance of irrigation in Saskatchewan is important to understand its contribution provincially and regionally as a possible tool for this economic development. The economic impacts of irrigation extend beyond farm-level impacts and understanding how it contributes to the entire economy at a provincial and regional level is information needed by decision makers. The purpose of this study is to provide the contributions of the irrigation sector on the provincial and regional economy.
The Saskatchewan Irrigation Impact Analyzer (SIIA) model was built as a part of this study. The SIIA was based on a regionalized rectangular input-output model of the irrigation sector. Base data for the model were obtained from Statistics Canada Transaction Tables for 2011. The model was regionalized into: The Lake Diefenbaker Development Area (LDDA) and the other regions of Saskatchewan. The original data for agriculture production were disaggregated into irrigated and dryland production, each further disaggregated to crop and livestock production sectors. The model was further augmented with an employment model. Two scenarios of irrigation development were tested in the study: First, irrigation development that occurred during 2011-2016; Second, new irrigation development through infill expansion. In addition, the marginal contribution of the irrigation activity on the lake Diefenbaker Development Area region was also undertaken, which required a survey of producers.
The study found that the total economic impacts of irrigation development during 2011-2016, enabling an additional 8,472 acres of irrigated production, amounted to 86.60 million in GDP contributions at market prices. This resulted in 1,179 full-time equivalent (FTE) employment years and 603.70 million in output (sales) responsible for 2,908 FTE employment years. This would amount to 240.89 million in gross domestic product (GDP) contributions at market prices, at 2011 dollars.
The study also found that regionally, irrigation provides an impetus for economic development. During the 2011 year, the marginal contribution of irrigation production, over and above the alternative of dryland production, was created through purchases of higher amounts of farm inputs, as well as spending of additional household income. These two avenues resulted in total economic impacts of 78.47 million in GDP contributions at market prices. In the region, $58.72 million in household income gains also were incurred as a result of the 1,323 FTE employment years generated. The study found the economic impacts of irrigation, currently and potentially, to be extensive in each scenario and offering considerable regional impacts over and above the dryland production alternatives
NAVIGATING BETWEEN ETHNIC AND RELIGIOUS IDENTITY: HERITAGE LANGUAGE MAINTENANCE AMONG YOUNG AUSTRALIANS OF INDONESIAN ORIGIN
For ethnic minority groups, speaking a heritage language signifies belonging to their country of origin and enriches the dominant culture. The acculturation of major ethnic groups in Australia – Greek, Italian, Chinese, Indian and Vietnamese – has been frequently studied, but a minor one like Indonesian has not. Through semi-structured interviews at various places and observations at cultural events, the study explores the contextual use, meaning and perceived benefits of Bahasa Indonesia (Indonesian language) among Indonesian families and how this practice influences the young participants’ (18-26 years old) identification with Indonesia, the origin country of their parents, and Australia, their current culture of settlement. The findings suggest that Bahasa Indonesia serves as a marker of ethnic and religious identity glued in family socialization. Parents believe that not only does the language signify their Indonesian ethnic identity, but also provides a means for socializing family values, and is beneficial for educational purposes and future career opportunities. However, parents face a dilemma whether to focus on ethnic or religious identity in socializing the use of Bahasa Indonesia. Interestingly, most young participants demonstrate a more global worldview by embracing both Indonesian and Australian values. How religious identity relates to more global worldview should be addressed more comprehensively in future studies
Combined analysis of microbial metagenomic and metatranscriptomic sequencing data to assess in situ physiological conditions in the premature infant gut.
Microbes alter their transcriptomic profiles in response to the environment. The physiological conditions experienced by a microbial community can thus be inferred using meta-transcriptomic sequencing by comparing transcription levels of specifically chosen genes. However, this analysis requires accurate reference genomes to identify the specific genes from which RNA reads originate. In addition, such an analysis should avoid biases in transcript counts related to differences in organism abundance. In this study we describe an approach to address these difficulties. Sample-specific meta-genomic assembled genomes (MAGs) were used as reference genomes to accurately identify the origin of RNA reads, and transcript ratios of genes with opposite transcription responses were compared to eliminate biases related to differences in organismal abundance, an approach hereafter named the "diametric ratio" method. We used this approach to probe the environmental conditions experienced by Escherichia spp. in the gut of 4 premature infants, 2 of whom developed necrotizing enterocolitis (NEC), a severe inflammatory intestinal disease. We analyzed twenty fecal samples taken from four premature infants (4-6 time points from each infant), and found significantly higher diametric ratios of genes associated with low oxygen levels in samples of infants later diagnosed with NEC than in samples without NEC. We also show this method can be used for examining other physiological conditions, such as exposure to nitric oxide and osmotic pressure. These study results should be treated with caution, due to the presence of confounding factors that might also distinguish between NEC and control infants. Nevertheless, together with benchmarking analyses, we show here that the diametric ratio approach can be applied for evaluating the physiological conditions experienced by microbes in situ. Results from similar studies can be further applied for designing diagnostic methods to detect NEC in its early developmental stages
Effect of room temperature transport vials on DNA quality and phylogenetic composition of faecal microbiota of elderly adults and infants
Background: Alterations in intestinal microbiota have been correlated with a growing number of diseases. Investigating the faecal microbiota is widely used as a non-invasive and ethically simple proxy for intestinal biopsies. There is an urgent need for collection and transport media that would allow faecal sampling at distance from the processing laboratory, obviating the need for same-day DNA extraction recommended by previous studies of freezing and processing methods for stool. We compared the faecal bacterial DNA quality and apparent phylogenetic composition derived using a commercial kit for stool storage and transport (DNA Genotek OMNIgene GUT) with that of freshly extracted samples, 22 from infants and 20 from older adults. Results: Use of the storage vials increased the quality of extracted bacterial DNA by reduction of DNA shearing. When infant and elderly datasets were examined separately, no differences in microbiota composition were observed due to storage. When the two datasets were combined, there was a difference according to a Wilcoxon test in the relative proportions of Faecalibacterium, Sporobacter, Clostridium XVIII, and Clostridium XlVa after 1 week's storage compared to immediately extracted samples. After 2 weeks' storage, Bacteroides abundance was also significantly different, showing an apparent increase from week 1 to week 2. The microbiota composition of infant samples was more affected than that of elderly samples by storage, with significantly higher Spearman distances between paired freshly extracted and stored samples (
Tumour-associated and non-tumour-associated microbiota in colorectal cancer
Objective: A signature that unifies the colorectal cancer (CRC) microbiota across multiple studies has not been identified. In addition to methodological variance, heterogeneity may be caused by both microbial and host response differences, which was addressed in this study. Design: We prospectively studied the colonic microbiota and the expression of specific host response genes using faecal and mucosal samples (‘ON’ and ‘OFF’ the tumour, proximal and distal) from 59 patients undergoing surgery for CRC, 21 individuals with polyps and 56 healthy controls. Microbiota composition was determined by 16S rRNA amplicon sequencing; expression of host genes involved in CRC progression and immune response was quantified by real-time quantitative PCR. Results: The microbiota of patients with CRC differed from that of controls, but alterations were not restricted to the cancerous tissue. Differences between distal and proximal cancers were detected and faecal microbiota only partially reflected mucosal microbiota in CRC. Patients with CRC can be stratified based on higher level structures of mucosal-associated bacterial co-abundance groups (CAGs) that resemble the previously formulated concept of enterotypes. Of these, Bacteroidetes Cluster 1 and Firmicutes Cluster 1 were in decreased abundance in CRC mucosa, whereas Bacteroidetes Cluster 2, Firmicutes Cluster 2, Pathogen Cluster and Prevotella Cluster showed increased abundance in CRC mucosa. CRC-associated CAGs were differentially correlated with the expression of host immunoinflammatory response genes. Conclusions: CRC-associated microbiota profiles differ from those in healthy subjects and are linked with distinct mucosal gene-expression profiles. Compositional alterations in the microbiota are not restricted to cancerous tissue and differ between distal and proximal cancers
Interdisciplinary Transgender Veteran Care: Development of a Core Curriculum for VHA Providers
Purpose: The Veteran\u27s Health Administration (VHA) has created a training program for interdisciplinary teams of providers on the unique treatment needs of transgender veterans. An overview of this program\u27s structure and content is described along with an evaluation of each session and the program overall. Methods: A specialty care team delivered 14 didactic courses supplemented with case consultation twice per month over the course of 7 months through video teleconferencing to 16 teams of learners. Each team, consisting of at least one mental health provider (e.g., social worker, psychologist, or psychiatrist) and one medical provider (e.g., physician, nurse, physician assistant, advanced practice nurse, or pharmacist), received training and consultation on transgender veteran care. Results: In the first three waves of learners, 111 providers across a variety of disciplines attended the sessions and received training. Didactic topics included hormone therapy initiation and adjustments, primary care issues, advocacy within the system, and psychotherapy issues. Responses were provided to 39 veteran-specific consult questions to augment learning. Learners reported an increase in knowledge plus an increase in team cohesion and functioning. As a result, learners anticipated treating more transgender veterans in the future. Conclusion: VHA providers are learning about the unique healthcare needs of transgender veterans and benefitting from the training opportunity offered through the Transgender Specialty Care Access Network-Extension of Community Healthcare Outcomes program. The success of this program in training interdisciplinary teams of providers suggests that it might serve as a model for other large healthcare systems. In addition, it provides a path forward for individual learners (both within VHA and in the community) who wish to increase their knowledge
Pre-notification letter type and response rate to a postal survey among women who have recently given birth
Background: Surveys are commonly used in health research to assess patient satisfaction with hospital care. Achieving an adequate response rate, in the face of declining trends over time, threatens the quality and reliability of survey results. This paper reports on a postal satisfaction survey conducted with women who had recently given birth, and explores the effect of two strategies on response rates. Methods: A sample of 2048 Australian women who had recently given birth were invited to participate in a postal survey about their recent experiences with maternity care. The study design included two different strategies intended to increase response rates: a randomised controlled trial testing two types of pre-notification letter (with or without the option of opting out of the survey), and a request for consent to link survey data with existing routinely collected health data (omitting the latter data items from the survey reduced survey length and participant burden). Results: The survey had an overall response rate of 46%. Women receiving the pre-notification letter with the option of opting out of the survey were more likely to actively decline to participate than women receiving the letter without this option, although the overall numbers of women were small (27 versus 12). Letter type was not significantly associated with the return of a completed survey. Among women who completed the survey, 97% gave consent to link their survey data with existing health data. Conclusions: Seeking consent for record linkage was highly acceptable to women who completed the survey, and represents an important strategy to add to the arsenal for designing and implementing effective surveys. In addition to aspects of survey design, future research should explore how to more effectively influence personal constructs that contribute to the decision to participate in surveys.NHMR
