Supplying energy has become one of the biggest concerns of developed countries due to the growing energy needs in the last decades. Utilising available renewable energy resources has been characterised as a reliable indicator, to reduce energy dependency in countries as well as securing the supplying of energy-based needs in the future. In this paper, a system dynamics approach has been utilised to illustrate the interrelationships between electricity/energy consumption, renewable energy resources as promotion plans, and energy dependency on imported resources. In order to illustrate benefits of renewable energy utilisation on reducing energy dependency, three different scenarios were developed and applied to the state of Illinois in the US to analyse the decrease in imported energy resources from external sources. The results of a computer simulation indicated that about 17 billion dollars can be saved by 2025 by reducing electricity/energy imports by implementing complete renewable energy action plans.
由于过去几十年来能源需求的增长,供应能源已成为发达国家最关心的问题之一。利用可用的可再生能源资源被认为是一个可靠的指标,可以减少各国对能源的依赖,并确保未来能源需求的供应。在本文中,利用系统动力学方法来说明电力/能源消耗、作为推广计划的可再生能源和能源对进口资源的依赖之间的相互关系。为了说明可再生能源利用对减少能源依赖的好处,开发了三种不同的情景,并将其应用于美国伊利诺伊州,以分析从外部来源进口能源的减少。计算机模拟结果表明,到2025年,通过实施完整的可再生能源行动计划,减少电力/能源进口,可以节省约170亿美元。

To retain a customer in a logistics industry is difficult as it highly depends on the customer relationship management (CRM) and the quality of the service delivered. The existing customers are to be retained for longer period of time for maximum profit contribution. Hence, it is important to perform a data analysis on the CRM data to identify the right segment of customers who are to be retained to maximise profit. This study segments the customers depending on the parameters recency, frequency, and the monetary value, known as RFM analysis. Customer lifetime value estimation is done on segments obtained using the RFM Analysis to identify the profit contribution of each of the segments. The analysis carried out aids the management to adopt decisions on marketing strategies based on the RFM scores and CLV of each segment. Company can also take decisions on budget spending in retaining the right customers.
在物流行业留住客户是很困难的,因为它高度依赖于客户关系管理(CRM)和所提供服务的质量。现有客户将保留更长的时间,以获得最大的利润贡献。因此,重要的是对CRM数据进行数据分析,以确定要保留的客户的正确部分,以实现利润最大化。该研究根据最近、频率和货币价值等参数对客户进行细分,称为RFM分析。客户生命周期价值评估是在使用RFM分析获得的细分市场上进行的,以确定每个细分市场的利润贡献。进行的分析有助于管理层根据每个细分市场的RFM分数和CLV采取营销策略决策。公司还可以在保留合适客户的预算支出方面做出决策。

Public transportation specifically mass rapid transit service like metro rail is vulnerable to the risk due to high customer traffic, visibility, accessibility and increasing security threat. Commuters are highly sensitive and concerned about their safety while travelling through public transport facility and safety and security measure of public transportation is one of the most significant drivers of customer satisfaction. In the present study, perception data was collected from all the 160 metro stations of Delhi Metro and both qualitative and quantitative research technique was employed to analyse the result. The result of the study depicts that presence and alertness of security personnel has most significant impact over commuter satisfaction followed by effectiveness of metal detector and safety provisions against accident and terrorist attack. This study opines that security services need to be reviewed in the light of changing security dynamics to counter any critical incident and unforeseen situation.
由于客流量大、能见度高、可达性高、安全威胁日益增加,公共交通特别是地铁等大规模快速交通服务容易受到风险的影响。通勤者在乘坐公共交通工具时对自身安全高度敏感和关注,而公共交通的安全和安保措施是影响顾客满意度的最重要因素之一。在本研究中,从德里地铁所有160个地铁站收集感知数据,并采用定性和定量研究技术对结果进行分析。研究结果表明,保安人员的存在和警惕性对通勤满意度的影响最为显著,其次是金属探测器的有效性和防止事故和恐怖袭击的安全措施。这项研究认为,保安服务需要根据不断变化的保安动态进行审查,以应对任何重大事件和不可预见的情况。

This paper examines the concept of 'risk loving' (that is risk seeking, intemperance, edginess, etc.), which can be characterised by preferences over simple lotteries. This paper analyses the notion of preferring to combine good with good, and bad with bad, as opposed to combining good with bad as usual. The significance of such preferences has implications on utility functions and are analysed in the paper. This paper extends Eeckhoudt and Schlesinger (2006) results to risk lovers, the results from Crainich et al. (2013) are also generalised to higher orders. We also generalise to higher orders the concept of bivariate risk seeking, introduced by Richard (1975) and called correlation loving by Epstein and Tanny (1980). In the expected utility framework, risk loving of order (N, M) coincides with the non-negativity of the (N, M)th partial derivative of the utility function. In dealing with mixed risk loving utility functions, we give several useful properties, for example, mixed risk loving is consistent with the mixture of positive exponential utilities and with non-increasing coefficients of absolute risk aversion at any order.
本文研究了“爱冒险”的概念(即追求风险、放纵、急躁等),其特征可以是对简单彩票的偏好。本文分析了倾向于将好与好、坏与坏结合起来的概念,而不是像往常一样将好与坏结合在一起。这种偏好的意义对效用函数有影响,本文对此进行了分析。本文将Eeckhoudt和Schlesinger(2006)的结果推广到风险爱好者,Crainich等人(2013)的结果也推广到更高阶。我们还将Richard(1975)提出的双变量风险寻求的概念推广到更高阶,Epstein和Tanny(1980)称之为相关性偏好。在期望效用框架中,阶(N,M)的风险偏好与效用函数第(N,M)阶偏导数的非负性一致。在处理混合风险偏好效用函数时,我们给出了几个有用的性质,例如,混合风险偏好与正指数效用的混合一致,并且与任何阶次的绝对风险厌恶系数不递增一致。

Recent economic crisis had dragged not only profit-oriented organisations into hard situation, non-profit organisations such as public universities in Malaysia also badly affected especially in term of limited budget allocation from government. Hence, public universities are facing tremendous challenge in sustaining their university performance especially in sustaining their ranking and reputation at the global arena. As a result, universities in Malaysia nowadays are encouraged to be more creative in wealth creation for financial sustainability. This study attempts to investigate alumni readiness to donate to their alma maters as a part of the financial sustainability agenda among public universities. The study among 311 millennials alumni from one of the well-known management-based university in Malaysia revealed that attitude towards donation, peer pressure and religiosity play a significant role in explaining donor behavioural intention. Besides, religiosity also found to mediate the relationship between attitude towards donation and donor behavioural intention. Implication and recommendation for future research also is discussed in this article.
最近的经济危机不仅使以营利为导向的组织陷入困境,马来西亚的公立大学等非营利组织也受到严重影响,特别是政府有限的预算拨款。因此,公立大学在保持其大学表现方面面临着巨大的挑战,特别是在保持其在全球舞台上的排名和声誉方面。因此,如今马来西亚的大学被鼓励在财富创造方面更具创造性,以实现财务可持续性。本研究试图调查校友是否愿意将捐赠给母校作为公立大学财务可持续性议程的一部分。对马来西亚一所知名管理型大学的311名千禧一代校友的研究表明,对捐赠的态度、同伴压力和宗教信仰在解释捐赠者行为意愿方面起着重要作用。此外,宗教信仰对捐赠态度与捐赠者行为意向之间的关系也有中介作用。本文还讨论了对未来研究的启示和建议。

This paper aims to explore and to make explicit of the existing safety climate assessment tools and dimensions. The concept of safety climate is firstly discussed with a review of different safety climate factors from the published literature. A qualitative research method was employed to explore the safety climate factors through a systematic review using four databases and specific keywords. A total of 68 papers were selected for the screening process. The screening process allowed to select the final 18 safety climate assessment tools and papers consisting of 98 safety climate factors spanning over a period of 39 years (1980 – 2019). Construction organizations may consider these factors to assess the current maturity level of their safety climate and to develop plans to achieve the required level. It is recommended that the factors discussed in this paper may be validated first before they are incorporated in the assessment of safety climate.
本文旨在探索并明确现有的安全气候评估工具和维度。首先讨论了安全气候的概念,并回顾了已发表的文献中的不同安全气候因素。采用定性研究方法,通过使用四个数据库和特定关键词的系统综述来探索安全气候因素。筛选过程共选择了68篇论文。筛选过程允许选择最终的18个安全气候评估工具和论文,包括跨越39年(1980-2019)的98个安全气候因素。施工组织可以考虑这些因素来评估其安全环境的当前成熟度水平,并制定计划以达到所需水平。建议在将本文中讨论的因素纳入安全气候评估之前,可以首先对其进行验证。

The mining industry, one of Canada's most important sectors, is opined to be experiencing productivity issues as one of its most important issues. We perform the first efficiency analysis of Canadian mining firms using data envelopment analysis. We compute technical, managerial and scale efficiencies for a sample of 30 listed mining firms during the period 2011-2015. Our results confirm that, overall, the firms exhibit low to average technical efficiencies, largely due to managerial inefficiencies. Further, their technical and managerial efficiencies have been declining during the 2011-2015 period. Finally, sub-sectorial analysis shows that gold and diamond, gemstones, platinum and precious metal mining firms perform the best on scale efficiency, while general mining companies set the standard for managerial efficiency.
采矿业是加拿大最重要的部门之一,被认为正经历着生产力问题,这是其最重要的问题之一。我们使用数据包络分析对加拿大矿业公司进行了首次效率分析。我们计算了2011-2015年期间30家上市矿业公司的技术、管理和规模效率。我们的研究结果证实,总体而言,这些公司的技术效率较低,主要是由于管理效率低下。此外,在2011-2015年期间,它们的技术和管理效率一直在下降。最后,细分行业分析表明,黄金和钻石、宝石、铂和贵金属矿业公司的规模效率表现最好,而普通矿业公司则制定了管理效率的标准。

First mover advantage on family firm succession 家族企业继承的先发优势
IF 0.7 Q4 MANAGEMENT Pub Date : 2019-07-01 DOI: 10.1504/IJAMS.2019.10022350

In spite of the proliferation of studies in various areas regarding the benefit of being first, the first mover advantage (FMA), in the context of family firms the work is (at best) scant. Adding to this, the impact that such firms have on the world economic stage it becomes both an interesting and a necessary research avenue. To study FMA in these firms, we will focus on one of the most critical stages in the lives of such firm: succession. As most of family firms do not outlive their founders, the passage of the executive power to the next generation is a crucial test that these firms face. It is not uncommon during this stage to see siblings rival to be nominated successor. This paper advances the succession game presented by Jayantilal et al. (2016), to study whether there is any advantage for the child who moves first in the succession race. The results indicate that indeed the first mover advantage exists, and that the emotional cost of conflict plays an important role in determining it.
尽管在各个领域关于先发优势的研究激增,但在家族企业的背景下,这项工作(充其量)很少。除此之外,这些公司对世界经济舞台的影响也成为一个有趣和必要的研究途径。为了研究这些公司的FMA,我们将关注这类公司生命中最关键的阶段之一:继任。由于大多数家族企业的寿命都比创始人长,因此将执行权传给下一代是这些企业面临的一个关键考验。在这一阶段,兄弟姐妹竞争被提名的继任者并不罕见。本文提出了Jayantilal等人提出的接班游戏。(2016),以研究在接班比赛中最先移动的孩子是否有任何优势。研究结果表明,先发优势确实存在,冲突的情感成本在决定这一优势中起着重要作用。

To study FMA in these firms, we will focus on one of the most critical stages in the lives of such firm: succession. As most of family firms do not outlive their founders, the passage of the executive power to the next generation is a crucial test that these firms face. It is not uncommon during this stage to see siblings rival to be nominated successor. This paper advances the succession game presented by Jayantilal et al. (2016), to study whether there is any advantage for the child who moves first in the succession race. The results indicate that indeed the first mover advantage exists, and that the emotional cost of conflict plays an important role in determining it.","PeriodicalId":38716,"journal":{"name":"International Journal of Applied Management Science","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41781700","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}

The purpose of this study is to analyse and measure the current service quality of Bahir Dar city hotels and design a house of quality to improve the service quality and competitiveness. SERVQUAL and quality function deployment (QFD) models are employed as a service quality measurement, design and customer satisfaction improvement tools. After prioritising customer needs, competitive assessments of hotel services were done from the customers' perspective using house of quality (HoQ). As a result of the differences between expectations and perceptions, service quality gaps are revealed in all hotel service quality dimensions. Generally, the results revealed that the overall hotels' services quality levels are bellow customers' expectations. According to the findings, technical requirements important to enhance service quality and meet customer satisfaction are identified and prioritised. Finally, a house of quality is designed to improve the service quality and competitiveness of hotels.
本研究的目的是分析和衡量巴伊尔达尔城市酒店目前的服务质量,并设计一个高质量的房子来提高服务质量和竞争力。SERVQUAL和质量功能部署(QFD)模型被用作服务质量测量、设计和客户满意度改进工具。在优先考虑客户需求后,使用质量屋(HoQ)从客户的角度对酒店服务进行竞争性评估。由于期望和感知之间的差异,所有酒店服务质量维度都存在服务质量差距。总体而言,结果显示,酒店的整体服务质量水平低于客户的预期。根据调查结果,确定并优先考虑了对提高服务质量和满足客户满意度至关重要的技术要求。最后,设计了一个精品之家,以提高酒店的服务质量和竞争力。
