While it may seem that salient visual events, like the flashing lights on an ambulance, can automatically capture our attention, capture is actually under our control. Depending on our current internal goals, we adopt attentional control settings (ACSs) that specify what stimuli in the environment capture our attention. It has been shown that ACSs can be defined based on long-term episodic memory representations. For example, when searching for the items on your grocery list, an ACS can be specified based on your long-term memory of the list, such that your attention will be drawn to those items, and only those items. Importantly, episodic memories incorporate contextual information that can enhance recall when reinstated (e.g., you will remember your grocery list better if it was memorized at the grocery store rather than at home). Here we asked whether reinstating context can enhance the establishment of long-term memory ACSs. Participants memorized two sets of 15 images of objects in a particular context (i.e., a coloured box in a particular spatial location), that they then searched for, inducing an episodic-based ACS for those objects. During the search task, this encoding context was either reinstated, or not. We found that individuals are able to flexibly switch between ACSs and sources of information. However, we did not find sufficient evidence for the effect of context on the establishment of ACSs or their flexibility. This study extends our understanding of the factors that influence memory-guided attention, and the impact of contextual reinstatement on the formation of ACSs.
虽然看起来明显的视觉事件,比如救护车上闪烁的灯光,可以自动吸引我们的注意力,但实际上,这种吸引是在我们的控制之下的。根据我们当前的内部目标,我们采用注意控制设置(ACSs)来指定环境中哪些刺激会引起我们的注意。研究表明,ACSs可以根据长期情景记忆表征来定义。例如,在搜索购物清单上的物品时,可以根据您对清单的长期记忆指定ACS,这样您的注意力就会被吸引到这些物品上,而且只会被吸引到这些物品上。重要的是,情景记忆包含了上下文信息,可以在恢复时增强回忆(例如,如果你在杂货店而不是在家里记住你的购物清单,你会记得更好)。在这里,我们想知道情境的恢复是否可以促进长期记忆ACSs的建立。参与者记住了两组15张特定环境中物体的图像(例如,一个特定空间位置的彩色盒子),然后他们搜索这些物体,诱导出基于情节的ACS。在搜索任务期间,这个编码上下文要么恢复,要么不恢复。我们发现,个人能够灵活地在ACSs和信息来源之间切换。然而,我们没有发现足够的证据表明语境对ACSs的建立或其灵活性的影响。本研究扩展了我们对影响记忆引导注意的因素,以及情境恢复对ACSs形成的影响的理解。

Advances made in the field of genetics have positively contributed to the ability to screen for genetic diseases. Preimplantation genetic screening  (PGS) is a type of Reproductive Genetic Screening that involves day 5 embryo biopsies and DNA testing prior to embryo implantation in the uterus. Historically, this DNA testing was performed using fluorescent in situ hybridization. However, this was deemed ineffective, so new procedures involving methods such as array comparative genomic hybridization and real time polymerase chain reaction have been implemented. As PGS technology develops, ethical issues arise, as well as a need for further research.
遗传学领域取得的进展对筛查遗传疾病的能力作出了积极贡献。胚胎植入前遗传筛查(PGS)是一种生殖遗传筛查,包括胚胎植入子宫前的第5天胚胎活检和DNA检测。历史上,这种DNA检测是使用荧光原位杂交进行的。然而,这被认为是无效的,所以新的程序涉及的方法,如阵列比较基因组杂交和实时聚合酶链反应已经实施。随着PGS技术的发展,伦理问题出现了,也需要进一步的研究。

This paper analyzes the forestry and logging industry in Crown forests in Ontario. We present historical trends on harvested areas, employment, revenue collected by the province, biophysical impacts, and revenue from the industry. We discuss the institutional context of Crown forest management in Ontario which includes a description of the Ministry of Natural Resources and Forestry (MNRF) and NGOs such as the Sustainable Forestry Initiative and the Forest Stewardship Council. We conclude that the current management of Crown forests in Ontario is not achieving maximum potential, as we found that there is a decline in employment and revenue from the industry. We recommend a Free Market Environmentalist (FME) approach to Crown forest management in Ontario. This approach involves common property management and the establishment of Forest Trusts.  Current management does not take into account externalities that FME would, which could enhance potential in order to achieve maximum employment and revenue. There is a lack of biophysical data being collected to document the impact on key wildlife species and there is a lack of transparency regarding the management of crown forests by the MNRF. The Haliburton forest was used as case study which emulates an example of a FME approach.  
本文分析了安大略省林冠森林的林业和伐木工业。我们介绍了采收面积、就业、省收入、生物物理影响和行业收入的历史趋势。我们讨论了安大略省皇冠森林管理的制度背景,其中包括对自然资源和林业部(MNRF)以及可持续林业倡议和森林管理委员会等非政府组织的描述。我们的结论是,安大略省目前的皇冠森林管理没有发挥最大的潜力,因为我们发现该行业的就业和收入都在下降。我们推荐一种自由市场环境主义者(FME)的方法来管理安大略省的皇冠森林。这一办法涉及共同财产管理和建立森林信托。目前的管理没有考虑到FME可能带来的外部因素,而这些因素可以提高潜力,以实现最大的就业和收入。缺乏收集的生物物理数据来记录对主要野生动物物种的影响,国家森林保护区对林冠森林的管理也缺乏透明度。哈里伯顿森林被用作案例研究,它模拟了FME方法的一个例子。

In the last several years, there has been an increase in interest in the history of Canada’s Indigenous peoples. This, in turn, has called attention to health-related topics such as the proportion of the Indigenous population which suffers from a psychological disorder. Using statistics drawn from Statistics Canada’s 2014 General Social Survey on Victimization, this study examines the percentage of respondents who report having a mental/psychological disorder and analyzes the percentage in terms of the heritage of the respondents. According to the findings, a larger proportion of Indigenous people reported having a psychological disorder than non-Indigenous people. The results, along with past literature, provide evidence which supports a statistically significant relationship between "Aboriginal group – Respondent" and "Mental/psychological disability status."
在过去几年中,人们对加拿大土著人民的历史越来越感兴趣。这反过来又引起人们注意与健康有关的问题,例如土著人口中患有心理障碍的比例。本研究使用加拿大统计局2014年关于受害的综合社会调查的统计数据,检查了报告患有精神/心理障碍的受访者的百分比,并分析了受访者遗产的百分比。根据调查结果,报告有心理障碍的土著人比非土著人的比例更大。本研究结果,连同以往的文献,提供证据支持“原住民族群-回答者”与“精神/心理残疾状况”之间的统计显著关系。

Crossing Boundaries: Images of Christina of Markyate in the St. Albans Psalter 跨越边界:圣奥尔本斯诗篇中马尔凯特的克里斯蒂娜形象
Pub Date : 2019-04-18 DOI: 10.21083/SURG.V11I0.3806
Carolyn Ann Hickey
The St. Albans Psalter is an English illuminated manuscript dating back to the twelfth  century. The psalter has been connected to Christina of Markyate, a twelfth-century anchoress,  for whom the work appears to have been made. Many images in the St. Albans Psalter depict the biblical figure Mary Magdalene, who is seen interacting with the boundaries of the colourful illustration. This article will study the images of Mary Magdalene in the St. Albans Psalter and will seek to re-evaluate her spiritual relationship with the twelfth-century recluse Christina of Markyate. Although the connection between Christina and Mary Magdelene has been recognized and reassessed, this study offers a contemporary outlook on the visual iconography, suggesting that this relationship is, in fact, far closer than previously demonstrated. By analyzing images in which the hand of Mary Magdalene crosses illustrated boundaries, this study will demonstrate the connection between these instances and Christina’s isolation within the boundaries of her anchoritic hold.
圣奥尔本斯诗篇是一份可以追溯到12世纪的英文彩绘手稿。这首赞美诗与12世纪的女祭司克里斯蒂娜(Christina of Markyate)有关,似乎是为她而作的。《圣奥尔本诗篇》中的许多图像都描绘了圣经人物抹大拉的玛利亚,她与彩色插图的边界相互作用。本文将研究圣奥尔本斯诗篇中抹大拉的玛利亚的形象,并试图重新评估她与十二世纪隐士马尔基亚特的克里斯蒂娜的精神关系。虽然克里斯蒂娜和抹大拉的玛丽之间的联系已经被认识和重新评估,但这项研究提供了一个当代视觉图像的观点,表明这种关系实际上比以前所证明的要紧密得多。通过分析抹大拉的玛丽的手越过插图边界的图像,本研究将证明这些实例与克里斯蒂娜在她的anchoritic hold的边界内的孤立之间的联系。

The genetic factors involved in functional food efficacy on cardiovascular disease etiology 遗传因素参与功能食品对心血管疾病病因的功效研究

While the impacts of modifiable and non-modifiable risk factors on chronic diseases such as cardiovascular disease (CVD) are widely established, the interactions between such coexisting risk factors and their subsequent effects on the promotion or suppression of CVD are less known. As part of the diet, functional foods are considered a modifiable factor that influence health beyond their basic nutritional value. The relationship between these functional foods and the underlying genome, along with their joint implication in health and disease, forms the focus of the emerging field of nutrigenomics. Reviewed in this paper are some prominent gene-diet interactions demonstrated in CVD etiology. Specifically, the interaction between foods such as phytosterols and isoflavones with genetic factors of the consuming population are examined in relation to CVD. By determining how nutritional intake affects genetics and vice versa, we create the potential to offer improved dietary guidelines to certain individuals, subgroups, or populations in order to maximize health benefits of specific diets.
虽然可改变和不可改变的危险因素对心血管疾病(CVD)等慢性疾病的影响已被广泛确立,但这些共存的危险因素之间的相互作用及其对CVD的促进或抑制的后续影响尚不清楚。作为饮食的一部分,功能性食品被认为是影响健康的一个可改变因素,超出了其基本营养价值。这些功能性食品与潜在基因组之间的关系,以及它们对健康和疾病的共同影响,形成了营养基因组学这一新兴领域的焦点。本文综述了在心血管疾病病因学中一些突出的基因-饮食相互作用。具体来说,植物甾醇和异黄酮等食物与食用人群的遗传因素之间的相互作用与心血管疾病的关系进行了研究。通过确定营养摄入如何影响基因,反之亦然,我们创造了为某些个人、亚群体或人群提供改进的饮食指南的潜力,以最大限度地提高特定饮食的健康益处。

Facets of Conscientiousness in Relation to Academic Performance Across Programs of Study 尽责性与学习成绩的关系

Conscientiousness and its six facets (competence, order, dutifulness, achievement striving, self-discipline and deliberation) were examined in relation to cumulative grade point average (GPA) for undergraduate university students. The aim was to determine the degree to which conscientiousness predicted a higher GPA for students in varying programs, and to compare these results to previous findings. The programs examined were psychology, business, science/engineering, and general arts (i.e. B.A. programs other than psychology). Students were screened using Johnson’s (2014) “IPIP-NEO-120” (a 120-item version of the International Personality Item Pool-NEO: which measures constructs similar to those in the NEO Personality Inventory). Multiple regression analyses of the data revealed variations in concurrent validity of the facets of conscientiousness across majors. For psychology students, only Competence predicted GPA. For science and engineering students, Competence, Dutifulness and Achievement Striving predicted GPA. For general arts, only Deliberation predicted GPA. None of the facets were significant predictors for business students. Conscientiousness was thus a significant predictor of GPA across all majors, but the key facets were dependent on the area of study. The only gender difference detected was at low conscientiousness, with females having a significantly higher GPA than males. Additional research is necessary to further explore the predictive validity of the other Big Five personality traits and their facets, for a wider range of academic majors on academic success. Implications involve the role personality traits could play to the decision to enrol in a specific program, and how professors may bettor teach/mentor students in different programs.
本研究考察了大学生的责任心及其六个方面(能力、秩序、责任心、成就追求、自律和深思熟虑)与累积平均绩点(GPA)的关系。其目的是确定尽责性在多大程度上预示着不同专业学生的GPA更高,并将这些结果与之前的研究结果进行比较。被调查的专业包括心理学、商学、科学/工程和文科(即除心理学以外的文学学士学位课程)。学生们使用Johnson(2014)的“IPIP-NEO-120”(国际人格项目池-NEO的120个项目版本:它测量的结构与NEO人格清单中的相似)进行筛选。数据的多元回归分析揭示了不同专业学生责任心各方面的并发效度存在差异。对于心理学专业的学生来说,只有能力能预测GPA。对于理工科学生来说,能力、责任心和努力成就预示着GPA。对于普通艺术,只有审议可以预测GPA。这些方面都不是商科学生的显著预测因素。因此,尽责性是所有专业GPA的重要预测指标,但关键方面取决于学习领域。唯一发现的性别差异是责任心较低,女性的GPA明显高于男性。需要进一步的研究来进一步探索其他五大人格特征及其方面对更广泛的学术专业对学业成功的预测有效性。影响包括性格特征在决定是否参加特定项目中所起的作用,以及教授如何在不同的项目中更好地教授/指导学生。

Habitat Selection by Two Species of Cleaner Fishes That May be Beneficial in Removing Sea Lice From Cultured Salmon 两种清洁鱼的栖息地选择可能有助于去除养殖鲑鱼的海虱
Pub Date : 2019-03-01 DOI: 10.21083/surg.v11i0.4656

Sea lice are detrimental ectoparasites that attach to Atlantic salmon causing physiological damage and costing farmers millions in inventory loss and treatments. Cleaner fishes have been introduced into sea cages to act as a biological control of sea lice which is likely a solution for Canadian salmon aquaculture industries. To improve cleaner fish foraging efficiency, this study seeks to determine the optimal habitat for cleaner fishes in Canadian aquaculture. I hypothesized that to be effective cleaner fishes, both the cunners and the lumpfish require habitats that provide them with shelter and places for rest because neither species live solely in the water column. My second hypothesis was that the cunners and the lumpfish require different habitats due to their different morphologies. Habitat comparisons were conducted with three habitats and a control in each individual fishes tank for a total of 8 cunners and 25 lumpfish. It was determined that only cunners required shelter, possibly due to the lumpfish’s ability to adhere to the glass tank walls for rest. Moreover, there was no significant difference in habitat preference between the two species. However, the lumpfish were less preferential between habitat and preferred three of the four habitats equally. It should be noted that the lumpfish and the cunners utilized the same habitats in separate ways to better fit their species-specific requirements; so future research on the co-existence of the two species could lead to increased foraging efficiency through two-species cleaner fish systems.
海虱是附着在大西洋鲑鱼身上的有害体外寄生虫,会造成生理损害,并给养殖者造成数百万美元的库存损失和治疗费用。清洁鱼被引入海笼,作为对海虱的生物控制,这可能是加拿大鲑鱼养殖业的解决方案。为了提高清洁鱼的觅食效率,本研究旨在确定加拿大水产养殖中清洁鱼的最佳栖息地。我假设,为了成为有效的清洁鱼,孔雀鱼和圆头鱼都需要栖息地,为它们提供庇护和休息的地方,因为这两种鱼都不完全生活在水中。我的第二个假设是,由于形态不同,孔雀鱼和圆头鱼需要不同的栖息地。在每个单独的鱼缸中,对8条康纳鱼和25条块状鱼进行了3个生境和一个对照的生境比较。人们确定只有鱼才需要庇护,可能是因为肿块鱼能够附着在玻璃水箱壁上休息。此外,两种植物的生境偏好无显著差异。然而,肿块鱼对栖息地的偏好程度较低,对四种栖息地中的三种都有同样的偏好。应当指出的是,圆头鱼和梭子鱼以不同的方式利用相同的生境,以便更好地满足其物种特有的需要;因此,未来对两种鱼类共存的研究可能会通过两种清洁鱼系统提高觅食效率。

Cleaner fishes have been introduced into sea cages to act as a biological control of sea lice which is likely a solution for Canadian salmon aquaculture industries. To improve cleaner fish foraging efficiency, this study seeks to determine the optimal habitat for cleaner fishes in Canadian aquaculture. I hypothesized that to be effective cleaner fishes, both the cunners and the lumpfish require habitats that provide them with shelter and places for rest because neither species live solely in the water column. My second hypothesis was that the cunners and the lumpfish require different habitats due to their different morphologies. Habitat comparisons were conducted with three habitats and a control in each individual fishes tank for a total of 8 cunners and 25 lumpfish. It was determined that only cunners required shelter, possibly due to the lumpfish’s ability to adhere to the glass tank walls for rest. Moreover, there was no significant difference in habitat preference between the two species. However, the lumpfish were less preferential between habitat and preferred three of the four habitats equally. It should be noted that the lumpfish and the cunners utilized the same habitats in separate ways to better fit their species-specific requirements; so future research on the co-existence of the two species could lead to increased foraging efficiency through two-species cleaner fish systems.","PeriodicalId":292569,"journal":{"name":"SURG Journal","volume":"411 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115601685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Rights-based Approach to Indigenous Sovereignty, Self-determination and Self-government in Canada 以权利为基础的加拿大土著主权、自决和自治方法

The United Nations Declaration on the Rights of Indigenous People (UNDRIP) calls for the right to self-determination, as self-determination is a prerequisite for Indigenous people to recongnize their political, social, economic, and collective human rights. Canada has historically been unsupportive of UNDRIP as the federal government considers UNDRIP at odds with Canadian sovereignty and existing Canadian institutions. While the right to self-government is currently protected under section 35 of the Constitution Act, 1982, it is defined narrowly and falls short of allowing meaningful self-government for the majority of Indigenous people.  This paper considers the conflicting nature of self-determination and self-government through considering the impact of Indigenous sovereignty on state sovereignity, an analysis of various approaches to self-government in Canada, and the feasability of adopting a rights-based approach to self-government. This paper concludes that utilizing a human rights-based approach to self-government addresses the perceived conflicts at the state-level while providing for the creation of meaningful self-government arrangements.  Self-government arrangements must be created by Indigenous communities for Indigenous communities in order to reflect the diverse needs of Indigenous people regardless of their territorial affiliation or formal Indian status.   
《联合国土著人民权利宣言》要求享有自决权,因为自决权是土著人民承认其政治、社会、经济和集体人权的先决条件。加拿大历来不支持开发计划署,因为联邦政府认为开发计划署与加拿大主权和现有的加拿大机构不一致。虽然自治的权利目前受到1982年《宪法法》第35条的保护,但它的定义很狭隘,不允许大多数土著人民进行有意义的自治。本文通过考虑土著主权对国家主权的影响,对加拿大各种自治方式的分析,以及采用基于权利的自治方式的可行性,来考虑自决和自治的冲突性质。本文的结论是,利用基于人权的自治方法解决了州一级的感知冲突,同时提供了有意义的自治安排的创建。土著社区必须为土著社区作出自治安排,以便反映土著人民的不同需要,不论其领土归属或正式的印第安人地位如何。

This research study provides a new model to evaluate early childhood development internationally by integrating perspectives from the disciplines of International Development and Early Childhood Care and Education. This new model, The Geographic Context Education Development Matrix, was developed through this piece of research and will assist in providing a deeper understanding of the intersectionality of these disciplines as they relate to early childhood development. This model helps to illustrate the scholarly gap in understanding the local perspectives of international development, specifically through short-term international volunteering in Dharamshala, India. Data was collected through an experiential learning project where the primary investigator volunteered for one month in a private school in Dharamshala. Following this participatory experience, qualitative semi-structured interviews were conducted with local teachers and parents. The purpose of this research was to ascertain the current effectiveness of international interventions in Early Childhood Care and Education, especially through international volunteers, in Dharamshala, India and provide insight into the barriers impeding sustainable Early Childhood Care and Education. Through the analysis of the data collected, it was evident that the practice of short-term international volunteering is not effective in supporting Early Childhood Care and Education in Dharamshala. Short term volunteers are not an effective intervention because they cannot address the most significant barriers faced by local educators, their support is generally unreliable, and their presence can, and often does, perpetrate neocolonial tendencies. 
本研究通过整合国际发展与幼儿保育与教育学科的视角,为幼儿发展的国际评价提供了一个新的模型。这个新的模型,地理环境教育发展矩阵,是通过这项研究开发出来的,它将有助于更深入地理解这些学科的交叉性,因为它们与儿童早期发展有关。这一模式有助于说明在理解国际发展的地方视角方面的学术差距,特别是通过在印度达兰萨拉的短期国际志愿服务。数据是通过一个体验式学习项目收集的,主要调查人员在达兰萨拉的一所私立学校志愿工作了一个月。在这种参与性体验之后,对当地教师和家长进行了定性的半结构化访谈。本研究的目的是确定目前国际干预在幼儿保育和教育方面的有效性,特别是通过国际志愿者,在印度达兰萨拉,并深入了解阻碍可持续幼儿保育和教育的障碍。通过对所收集数据的分析,很明显,短期国际志愿服务的做法在支持达兰萨拉的幼儿保育和教育方面并不有效。短期志愿者并不是一种有效的干预手段,因为他们无法解决当地教育工作者面临的最重要的障碍,他们的支持通常是不可靠的,而且他们的存在可能,而且经常会造成新殖民主义倾向。
