The vision regarding the development of the business environment from the Romanian seaside area cannot exclude the positioning of the tertiary sector at the center of this approach by capitalizing the natural potential. Tourism development triggers an increased demand for goods and services related to this activity, thus stimulating the tertiary sector of the economy. The uniqueness of the resources of the Black Sea coast can contribute to the economic growth of the area, which should be exploited in accordance with the principles professed by sustainable tourism.
关于从罗马尼亚海滨地区发展商业环境的设想不能排除通过利用自然潜力将第三部门置于这一方法的中心。旅游业的发展增加了对与旅游业有关的商品和服务的需求,从而刺激了经济的第三部门。黑海沿岸资源的独特性可以促进该地区的经济增长,应根据可持续旅游业所宣称的原则对其进行开发。

This research paper considers how Sri Lankan export farmers currently interact with agricultural knowledge resources and the factors that affect such access. Access to agricultural knowledge resources at the required time is important for farmers to achieve required growing standards. This is particularly important for farmers in Sri Lanka aiming to sell to export markets. Integration into export value chains can greatly benefit farmers. However in order to access global value chains farmers have to meet required standards. The Department of Agriculture (DOA) of Sri Lanka is currently in the process of implementing Good Agricultural Practices (GAP) standards which must be met by farmers intending to sell to certain export markets. Currently there are several ways in which farmers can access this information; verbally by talking to agricultural extension officers, by calling the 1920 crop advisory service run by the DOA, or by looking at print copies of the GAP standards maintained at the Department. However farmers access this information alongside many other sources, including traditional practices. This research looks at the factors that affect how selected export farmers in Sri Lanka are included in or excluded from agricultural information, and the factors that affect the ways in which they act on the information. Multiple sources of information are considered – both formal and informal. The research considers how different aspects of farmer identity affects the ability of the subjects to access the information. The study also looks at how farmers act when faced with conflicting information from different sources. How do farmers balance conflicting information and the role that trust in information sources plays is considered. This study is part of a larger action-research-based study in which farmers were given mobile phones with information about GAP standards. However, for the purposes of this research, the selected farmers have not been exposed to this intervention.
本研究考虑斯里兰卡出口农民目前如何与农业知识资源互动,以及影响这种获取的因素。在必要的时间获得农业知识资源对农民达到所需的生长标准至关重要。这对打算向出口市场销售产品的斯里兰卡农民来说尤为重要。融入出口价值链可以极大地惠及农民。然而,为了进入全球价值链,农民必须达到所需的标准。斯里兰卡农业部(DOA)目前正在实施良好农业规范(GAP)标准,打算向某些出口市场销售的农民必须符合这些标准。目前,农民可以通过几种方式获取这些信息;口头上,通过与农业推广官员交谈,打电话给农业部经营的1920年作物咨询服务,或者通过查看农业部保存的GAP标准的打印副本。然而,农民可以与许多其他来源一起获得这些信息,包括传统做法。本研究着眼于影响斯里兰卡选定的出口农民如何纳入或排除在农业信息之外的因素,以及影响他们对信息采取行动的方式的因素。考虑多种信息来源——包括正式的和非正式的。该研究考虑了农民身份的不同方面如何影响受试者获取信息的能力。该研究还考察了农民在面对来自不同来源的相互矛盾的信息时如何采取行动。考虑了农民如何平衡冲突信息以及对信息源的信任所起的作用。这项研究是一项基于行动研究的大型研究的一部分,在这项研究中,农民们获得了带有GAP标准信息的手机。然而,为了本研究的目的,选定的农民没有接触到这种干预。

This article systematically presents the role of the Lahore High Court (LHC) in developing Islamic family law in Pakistan. The LHC was established one hundred and fifty years ago and has contributed significantly in this area of law. The gender sensitive and children friendly approach of the LHC in the domain of family law is evident by its numerous decisions. This approach on the one hand is inspired and informed by the ethos and spirit of Islamic dictates and on the other, by the day-to-day realities of the socio-economic condition of women and children in the institution of marriage. The court has attempted to keep the rights of these marginalized segments in sight and protect them instead of toeing precedents in a straitjacketed/mechanical manner. The fluid milieu of difference of opinions among scholars in Islamic legal texts (fiqh) has been innovatively employed so as to put it in service of women and children. The same approach is also demonstrated through the progressive construction of statutes.
本文系统地介绍了拉合尔高等法院(LHC)在巴基斯坦发展伊斯兰家庭法中的作用。大型强子对撞机成立于150年前,在这一法律领域做出了重大贡献。LHC在家庭法领域对性别问题敏感和对儿童友好的做法在其众多决定中得到了体现。这种做法一方面受到伊斯兰教规的风气和精神的启发和影响,另一方面受到婚姻制度中妇女和儿童的日常社会经济状况的现实的启发和影响。法院试图关注这些边缘化群体的权利并保护他们,而不是以束缚/机械的方式遵从先例。在伊斯兰法律文本(fiqh)方面,学者之间意见分歧的流动环境已被创造性地利用,以便使其为妇女和儿童服务。同样的方法也通过法规的渐进式构建得到证明。

Management of Spatial Development in Central Asia Through Transport Projects 通过交通项目管理中亚的空间发展
Pub Date : 2017-10-12 DOI: 10.2139/ssrn.3081880
L. Spankulova, Adilet Kongyrbay
This article analyses the idea of forming reliable lines of goods and capital supply with the use of logistics materials from the countries of Central Asia, Afghanistan and Pakistan, which made it possible to identify priority areas in the construction of trade and logistics centres. The geopolitical aspects of the "New Silk Road" plan, the transit potential of Afghanistan as a key country in the Middle East are also discussed. The goal of the "New Silk Road" project is the formation of reliable supply lines that will allow the countries of Central Asia to integrate with the markets of goods and capital in the West (Europe) and in the East (China). This requires not only investment in transport infrastructure, but also measures to reduce trade costs and fragmentation of supplies across the borders of member countries. Euro-Asian integration will become a prerequisite for increasing the transit potential of Central Asia on the modern Silk Road.
本文分析了利用中亚、阿富汗和巴基斯坦等国的物流物资形成可靠的货物和资本供应线的想法,这使得确定建设贸易和物流中心的优先领域成为可能。本文还讨论了“新丝绸之路”计划的地缘政治方面,以及阿富汗作为中东关键国家的过境潜力。“新丝绸之路”项目的目标是形成可靠的供应线,使中亚国家能够与西方(欧洲)和东方(中国)的商品和资本市场相结合。这不仅需要对运输基础设施进行投资,还需要采取措施降低贸易成本,减少成员国之间供应的分散。欧亚一体化将成为提升中亚在现代丝绸之路上过境潜力的先决条件。

As wolf populations expand across Europe, many countries face challenges in finding ways to address the concerns of some elements among the rural stakeholders who are being asked to share their landscapes with wolves for the first time in several generations. In these recovery landscapes, wolves are associated with a wide range of conflicts that include economic, psychological, perceptional, social, cultural and political dimensions. A recurring demand concerns the desire to introduce the use of carefully regulated lethal control of wolves, through either culling by state employees or hunting conducted by rural hunters. Introducing such measures can be very controversial, and many critics challenge their legality under the international wildlife conservation instruments that have nurtured wolf recovery. We evaluate this issue for the case of wolves in Norway, which are strictly protected under the Bern Convention. Drawing on the latest results of social science research, we present the multiple lines of argumentation that are often used to justify killing wolves and relate these to the criteria for exceptions that exist under the Bern Convention. We conclude that while the Convention provides apparent scope for allowing the killing of wolves as a means to address conflicts, this must be clearly justified and proportional to the conservation status of wolves so as to not endanger their recovery.
随着狼的数量在整个欧洲扩张,许多国家面临着寻找方法来解决农村利益相关者中一些因素的担忧的挑战,这些利益相关者几代人以来第一次被要求与狼分享他们的景观。在这些恢复景观中,狼与广泛的冲突有关,包括经济、心理、感知、社会、文化和政治层面。一项反复出现的要求是,希望通过政府雇员的扑杀或农村猎人的狩猎,对狼实行严格监管的致命控制。引入这样的措施可能会引起很大的争议,许多批评者质疑其合法性,因为国际野生动物保护文书促进了狼的恢复。我们以挪威的狼为例来评估这个问题,它们受到《伯尔尼公约》的严格保护。根据社会科学研究的最新成果,我们提出了经常被用来证明捕杀狼是正当的多种论证,并将这些论证与《伯尔尼公约》中存在的例外标准联系起来。我们得出的结论是,虽然《公约》为允许捕杀狼作为解决冲突的一种手段提供了明显的余地,但这必须明确合理,并与狼的保护状况成比例,以免危及它们的恢复。

The Role of Consumption in Peaking China's Carbon Emissions by 2030 消费在2030年中国碳排放达到峰值中的作用

China promised to peak its total carbon emissions by 2030. Various actions on both supply and demand sides have been studied to achieve the goal. However, should the consumption be influenced purposefully for environmental purposes is still been hotly debated in the literature. By re-conceptualizing the definition of consumption, this study combines various modeling techniques with input-output analysis and evaluates quantitatively the role of consumption in carbon peak by 2030. We find that, without proper interventions on technology and consumption levels, China’s energy use and carbon emissions will continuously increase without a peak before 2050. To achieve carbon peak by 2030, China would have to achieve higher energy efficiency. Alternatively, China can choose to influence the consumption levels of the domestic consumers. In this case, Chinese people will live a life which is still less wasteful than that in the USA but with the same living standards to those in Japan and European countries. However, the GDP output, in this case, is approximately 11% lower in 2050 than the counterpart when the consumption levels grow without control and ultimately exceed the US consumption levels.
中国承诺到2030年达到碳排放总量的峰值。为了实现这一目标,研究了供需双方的各种行动。然而,消费是否应该有目的地影响环境的目的,仍然是在文献中激烈的争论。通过重新定义消费的定义,本研究将各种建模技术与投入产出分析相结合,定量评估了消费在2030年碳峰值中的作用。研究发现,如果不对技术和消费水平进行适当的干预,中国的能源使用和碳排放将持续增加,在2050年之前不会达到峰值。为了在2030年达到碳排放峰值,中国必须提高能源效率。或者,中国可以选择影响国内消费者的消费水平。在这种情况下,中国人的生活将比美国人更少浪费,但与日本和欧洲国家的生活水平相同。然而,在这种情况下,2050年的GDP产出比消费水平不受控制地增长并最终超过美国消费水平时的GDP产出低约11%。

A High-Resolution, Yet Scalable Framework for Transport Infrastructure Accessibility Based on Open Big Data 基于开放大数据的高分辨率、可扩展交通基础设施可达性框架
Pub Date : 2017-09-06 DOI: 10.2139/ssrn.3033166

Throughout the last years, open big data has brought many challenges and revealed much potential for transportation research. In this study, we show how large open datasets can be used to accurately estimate the accessibility of transportation infrastructure for whole China, a scale unprecedented in the literature. Hundreds of airports and almost one thousand high-speed railway (HSR) stations serve the tremendously growing transportation demand. These access points to the transportation networks are not equivalently distributed throughout the country. Existing large-scale studies on transportation infrastructure accessibility focus on highly-aggregated forms of land-use area, with travel times from centroids of administrative regions. Other studies analyze spatially-constrained regions with very detailed data. In this study, we design and implement a fine-grained accessibility framework based on large open data sets, which allows us to estimate the accessibility based on grid cells with a resolution of less than one square kilometer. We automatize the computation of free-flow road travel times, as well as, the public transit times, from grid cells to infrastructure elements, by using a scalable routing framework. Based on our experiments, we find that the HSR network for China is much better accessible for the population than airports. Moreover, grid cells with a high population density are much better connected to the Chinese transportation networks than other grid cells. Our methodology is generic in that it can be applied on an even larger scale (whole planet) and with different points of interest.
在过去的几年里,开放的大数据给交通研究带来了许多挑战,也揭示了很大的潜力。在本研究中,我们展示了如何使用大型开放数据集来准确估计整个中国交通基础设施的可达性,这是文献中前所未有的规模。数以百计的机场和近一千个高铁车站满足了日益增长的交通需求。这些通往交通网络的接入点在全国各地分布不均。现有关于交通基础设施可达性的大规模研究侧重于土地利用面积的高度聚集形式,其旅行时间来自行政区域的中心点。其他研究用非常详细的数据分析空间受限的区域。在这项研究中,我们设计并实现了一个基于大型开放数据集的细粒度可达性框架,使我们能够基于分辨率小于1平方公里的网格单元来估计可达性。我们通过使用可扩展的路由框架,自动计算自由流动的道路旅行时间,以及公共交通时间,从网格单元到基础设施元素。根据我们的实验,我们发现中国的高铁网络比机场更便于人们使用。此外,人口密度高的网格单元与中国交通网络的连接比其他网格单元要好得多。我们的方法是通用的,因为它可以应用于更大的规模(整个地球)和不同的兴趣点。

The Program for International Student Assessment (PISA) has deservedly become the benchmark for comparing national K-12 school systems. Since 2000, the OECD has, at three year intervals, organized PISA “rounds” to assess school system performance in member countries and in non-member partner countries, among upper-secondary students, age 15, in three core subjects. This Commentary summarizes major conclusions relevant to Canada from the latest round, in 2015. The policy recommendation of this Commentary is implicit: educators, administrators and parents should make use of PISA results as a guide to strategic priorities for education policy. Canada’s overall PISA score has consistently ranked well above the OECD average on the three subjects assessed (reading, mathematics, and science). In 2015, Canada ranked 10th in mathematics, 3rd in reading, 7th in science. Overall, our school system is faring well. However, PISA provides ample evidence to prompt some humility among Canadians. To be more specific: • Trends in mathematics: Since the inauguration of PISA, Canadian performance in mathematics has consistently declined from one round to the next, and the gap between 2003 and 2015 results is statistically significant. • Gender gaps: Canada is not faring well on this dimension; it is close to the OECD average. There exist in Canada modest gender gaps in mathematics and science that favour boys. A much larger gender gap in reading favours girls. • Mediocre outcomes for the six small provinces, for Manitoba and Saskatchewan in particular: From the base year for each subject to 2015, PISA score declines in all three subjects have been statistically significant for Manitoba and Saskatchewan. In all three subjects, the levels in these provinces are now below the benchmark year OECD average. There are reasons to speculate that the high proportion of Indigenous students in Manitoba and Saskatchewan is a key factor in explaining their PISA performance. Relative to these two Prairie provinces, outcomes are better in the four Atlantic provinces, but they, too, are not faring well. Each of the four has one 2015 score below 500; among the four, all scores are below the relevant national Canadian average.
国际学生评估项目(PISA)当之无愧地成为比较各国K-12学校系统的基准。自2000年以来,经合组织每隔三年组织一次PISA“轮次”,以评估成员国和非成员国伙伴国家的学校系统在三个核心科目上15岁高年级学生的表现。本评论总结了2015年最新一轮谈判中与加拿大有关的主要结论。本评论的政策建议是隐含的:教育工作者、管理人员和家长应该利用PISA结果作为教育政策战略优先事项的指南。加拿大在国际学生评估项目(PISA)评估的三个科目(阅读、数学和科学)上的总体得分一直高于经合组织的平均水平。2015年,加拿大数学排名第10,阅读排名第3,科学排名第7。总的来说,我们的学校系统运行良好。然而,PISA提供了充分的证据,促使加拿大人保持谦逊。更具体地说:•数学趋势:自PISA启动以来,加拿大人在数学方面的表现一直在一轮接一轮地下降,2003年和2015年之间的差距在统计上是显著的。•性别差距:加拿大在这方面表现不佳;接近经合组织的平均水平。加拿大在数学和科学方面存在着有利于男孩的适度性别差距。阅读方面的性别差异更大,女孩更受青睐。•六个小省份的成绩一般,尤其是马尼托巴省和萨斯喀彻温省:从每个科目的基准年到2015年,马尼托巴省和萨斯喀彻温省的所有三个科目的PISA分数下降在统计上都很显著。在这三个科目中,这些省份的水平现在都低于经合组织的基准年平均水平。有理由推测,曼尼托巴省和萨斯喀彻温省土著学生的高比例是解释他们PISA表现的关键因素。相对于这两个大草原省份,大西洋四省的结果要好一些,但它们的情况也不太好。2015年,这四个国家都有一个得分低于500;在这四名学生中,所有的分数都低于加拿大全国平均水平。

Discovery of Social Beliefs About Ethnic Structure from Survey Data 从调查数据中发现关于族群结构的社会观念
Pub Date : 2017-08-08 DOI: 10.2139/ssrn.3016017

This paper introduces a new approach to discovering and exploring society-wide social beliefs about ethnic structure. Rooted in computational text analysis, it combines the strengths of both qualitative and survey-based approaches to the study of ethnicity. I use a structural topic modeling approach (Roberts, Stewart, and Airoldi 2016) to uncover general patterns in found in open-ended questions about ethnic groups. I then predict which patterns of responses tend to be associated with which ethnic groups, and use information about survey respondents to explore heterogeneity in social beliefs. To illustrate the method at work, I use original survey data from Malaysia, collected in 2017, to understand social beliefs about Malay, Chinese, Indian, and Arab ethnic groups in Malaysia.
本文介绍了一种新的方法来发现和探索有关种族结构的全社会社会信念。植根于计算文本分析,它结合了定性和基于调查的方法的优势来研究种族。我使用结构主题建模方法(Roberts, Stewart, and Airoldi 2016)来发现关于种族群体的开放式问题中的一般模式。然后,我预测哪一种反应模式倾向于与哪一种族群体有关,并利用调查对象的信息来探索社会信仰的异质性。为了说明这种方法的有效性,我使用了2017年收集的马来西亚原始调查数据,以了解马来西亚马来人、华人、印度人和阿拉伯人群体的社会信仰。
