    摘要
    隨著物流外包的重要性增加和物流服務供應商(LSP)的可用性,LSP的評估和選擇過程的重要性和複雜性得到了凸顯。現有的LSP評估和選擇研究大多使用歷史性能數據並假設決策標準間是獨立的。本文提出了一種基於其物流資源和能力來評估和選擇LSP的綜合物流外包方法。這種新方法結合了模糊決策制定試驗、評估實驗室(FDEMATEL)和模糊技術以依據相似度排序偏好(FTOPSIS)方法。新的多標準決策制定(MCDM)模型解釋了決策標準間的影響關係,並根據加權的資源和能力對LSP替代方案進行排序。通過一個真實案例研究示範了這種方法的有效性,並通過兩階段敏感性分析確認了其強健性。
    主要內容
    引言:討論了物流外包的日益增長的需求和LSP的評估和選擇過程的重要性。
    背景:物流外包已經成為實現競爭優勢、改善客戶服務和降低物流成本的有效方式。
    文獻回顧:研究了不同視角的LSP的策略性資源和其對LSP績效的影響。
    混合模型:使用Mentzer等人的一般資源分類和RBL理論來發展LSP資源和能力模型。
    FDEMATEL:進行了問卷調查以獲得物流專家的意見,並探討了他們的看法。
    結論:提出了一種基於物流資源和能力的LSP評估和選擇的新技術。
    致謝:感謝兩位匿名評論者的貢獻和對改進手稿的建議。這項研究得到了Yarmouk大學的支持。 總之,這篇論文提出了一種新的基於物流資源和能力的LSP評估和選擇方法,並進行了實證研究來驗證其有效性。這種新方法克服了過去只基於LSP的表現數據進行評估的局限性,並對物流資源和能力進行了深入的分析。



  • FDEMATEL 是 Fuzzy Decision Making Trial and Evaluation Laboratory 的縮寫,意思是模糊決策實驗室分析法。它是在 DEMATEL 的基礎上,引入模糊理論,來處理不確定性和主觀性的問題。它可以將問卷調查中的語言變數轉換為模糊數,並利用模糊運算來建立直接影響矩陣、規範化直接影響矩陣和總關係矩陣,從而分析各要素之間的因果關係和重要程度。

    Multi-objective optimization of petroleum product logistics in Eastern Indonesia region
    印尼東部地區成品油物流多目標最佳化
    Abstract
    The transportation sector is one of the largest fuel consumers and pollutant contributors worldwide. The International Maritime Organization predicts that the greenhouse gas (GHG) emissions from transportation will be increasing significantly until 2050, driven by the growth in global maritime trade. Managing logistics distribution routes is considered a possible approach for controlling GHG emissions. This study aims to implement a green logistics concept in the logistics distribution of petroleum products—gasoline, kerosene, and diesel—in eastern Indonesia, whose supply sources are refineries located in Balikpapan and Kasim. A multi-objective approach is used to implement the green logistics concept. Multi-objective optimization is conducted using the AIMMS software to optimize a logistics system consisting of a multidepot, multi-product, and heterogeneous fleet. The optimization is performed to determine the best logistics route and the amount of products delivered using certain types of fleets to minimize transportation cost and GHG emissions using constant speed. In addition, this study also investigates the effect of variable speed on cost and CO2 emissions. For the constant speed case, the distribution routes obtained for the minimizing cost scenario tends to maximize the utilization of transit terminals while in the minimizing emissions scenario tends to deliver directly to the distribution centers, so the route decision in multi-objective optimization scenario is combination of the two. The multi-objective optimization results an 11% cost reduction and a 17% GHG emission reduction compared with the current values. The comparison between constant and variable speed reveals that the variable speed is preferred to constant speed as it gives lower emissions with slight changes in cost. © 2021 The Authors.

    Summary:
    The abstract discusses the significance of the transportation sector in terms of fuel consumption and greenhouse gas (GHG) emissions. It highlights the prediction of increased GHG emissions in transportation, particularly in global maritime trade, until 2050. The study focuses on implementing a green logistics concept for the distribution of petroleum products (gasoline, kerosene, and diesel) in eastern Indonesia. It employs multi-objective optimization using AIMMS software to optimize a logistics system involving multiple depots, products, and a heterogeneous fleet. The optimization aims to find the best logistics routes and product quantities to minimize transportation costs and GHG emissions. Additionally, the study explores the impact of variable speed on costs and CO2 emissions. The results show that multi-objective optimization leads to an 11% cost reduction and a 17% GHG emission reduction compared to current values. Furthermore, variable speed is preferred over constant speed due to lower emissions with only slight cost changes.

    Abstract
    Reverse logistics (RL) has strategic importance. However, little is known concerning what motivates firms to adopt RL systems. Drawing on stakeholder theory formulations, organizational slack, and the manager's strategic stance concept, this article develops a model that proposes external, internal, and individual factors that affect the implementation of RL programs. Our framework considers three major explicative variables: the attributes of the stakeholder (power, legitimacy and urgency), organizational slack for RL programs, and the manager's strategic posture. The study draws on a sample of 118 Spanish companies and uses a probit model to determine the influence of these factors on the probability of firms to implement RL systems. The study finds that customers, employees, and the government salience in terms of RL activities and manager's progressive posture have a significant influence on the final decision of implanting RL programs. Conversely, the study finds that shareholder salience negatively impacts the decision.

    ChatGPT: Summary:
    This study focuses on understanding the factors that motivate firms to adopt reverse logistics (RL) systems, which involve the process of handling products in the reverse supply chain. The study draws on stakeholder theory, Organizational slack, and the manager's strategic stance concept concept to develop a model that considers external, internal, and individual factors affecting RL program implementation. Three major explicative variables in the model are: attributes of stakeholders (power, legitimacy, and urgency), organizational slack dedicated to RL programs, and the manager's strategic posture. The study uses a sample of 118 Spanish companies and employs a probit model to analyze how these factors influence the likelihood of firms implementing RL systems. Notably, the study finds that customers, employees, and government influence related to RL activities, as well as a manager's progressive strategic posture, positively impact the decision to implement RL programs. In contrast, shareholder influence negatively affects this decision.

    「manager's strategic stance concept」是一個關於[組織如何選擇和執行不同的競爭策略的理論框架]。根據這個概念,組織可以採取以下[三種基本的策略立場]
    • 探索者(prospector):這種組織會不斷地尋找和開發新的市場和產品,以創造和滿足客戶的需求。它們會冒險創新,快速適應變化,並且具有高度的彈性和學習能力。
    • 防禦者(defender):這種組織會專注於現有的市場和產品,以保持和提高其競爭優勢。它們會堅持穩定的目標,強調效率和成本控制,並且具有高度的一致性和規範性。
    反應者(reactor):這種組織沒有明確的策略方向,只是被動地應對外部環境的壓力和變化。它們缺乏長遠的視野,缺乏內部的協調,並且具有低度的主動性和效能感。
    不同的策略立場會影響組織的績效,也會要求組織使用不同的策略管理系統來監測和評估其策略執行的成果。作為一個管理者,你需要了解你所在的組織採取了哪種策略立場,並且根據其特點來[分配工作、建立關係、制定決策、解決問題等]


    以下介紹的也是RL program 但是論文中應該不是這個意思,指的應該是Reverse logistics program的意思!
    「RL program implementation」是指使用強化學習(Reinforcement Learning,RL)的方法來實現一個程式,讓程式能夠通過與環境的互動和獲得的回饋來學習和優化自己的行為。強化學習是機器學習的一個分支,它可以讓程式在沒有明確指導或監督的情況下,自主地探索和發現最佳的策略。 強化學習的程式實現需要定義以下幾個要素
    • 代理(agent):代理是指執行強化學習的程式,它可以根據自己的觀察和經驗來選擇合適的行動。
    • 環境(environment):環境是指代理所處的外部世界,它會根據代理的行動來改變自己的狀態,並給予代理一定的回饋。
    • 行動(action):行動是指代理可以在每個時刻選擇執行的操作,例如移動、轉向、攻擊等。
    • 狀態(state):狀態是指代理和環境在某個時刻的情況,例如位置、速度、血量等。
    • 回饋(reward):回饋是指環境對代理行動的評價,通常是一個數值,表示代理有多好或多壞地完成了目標。回饋可以是正數、負數或零,代表獎勵、懲罰或中立。
    強化學習的程式實現需要使用一些特定的算法來更新和優化代理的策略,使其能夠在長期內最大化累積回饋。這些算法有很多種類,例如Q學習、SARSA、深度Q網路等。這些算法通常需要建立一個稱為Q函數或價值函數的數學模型,來估計每個狀態下每個行動的期望回饋。然後,代理可以根據這個模型來選擇最有利或最有可能帶來高回饋的行動。
    強化學習的程式實現可以用不同的程式語言來完成,例如Python、C++、Java等。其中Python是比較常用和方便的選擇,因為它有很多支援強化學習開發和測試的函式庫和工具,例如OpenAI Gym、TensorFlow、PyTorch等。這些工具可以幫助程式設計師快速地建立和評估不同的強化學習模型和算法。

    Dependent Variable::
    The dependent variable in this study is the probability of firms implementing reverse logistics (RL) systems. This variable represents the final decision of whether or not a company adopts RL programs.

    Independent Variables:
    The independent variables in this study include three major factors: attributes of stakeholders (power, legitimacy, and urgency), organizational slack allocated for RL programs, and the manager's strategic posture. These independent variables are examined to understand their influence on the likelihood of firms implementing RL systems. Additionally, specific stakeholder groups (customers, employees, government, and shareholders) are considered as independent variables to evaluate their salience and impact on the decision-making process.

      This empirical study focuses on the field of reverse logistics within the context of green supply chain management. It examines the effects of five commonly adopted disposition options (repair, recondition, remanufacture, recycle, and disposal) on measures of environmental performance, profitability, and sales growth. The study also investigates the moderating role of regulatory and ownership pressures on the relationship between each disposition option and performance levels.

      Dependent Variable:

      Environmental Performance: This is one of the dependent variables, and the study seeks to understand how the different reverse logistics disposition options impact a company's environmental performance. Environmental performance refers to how environmentally friendly and sustainable a company's operations and products are.

      Profitability: Profitability is another dependent variable. The study aims to determine how the choice of reverse logistics disposition options influences a company's financial performance, particularly in terms of profitability.
      Sales Growth: Sales growth is the third dependent variable. The research examines how the various disposition options for reverse logistics impact a company's sales growth.
      Independent Variables:
      The independent variables in this study are the five reverse logistics disposition options:
      - Repair: The process of fixing and restoring products to their original functionality.
      - Recondition: The process of refurbishing products to improve their condition and functionality.
      - Remanufacture: The process of disassembling and rebuilding products to a like-new condition.
      - Recycle: The process of breaking down products into reusable materials or components.
      - Disposal: The process of discarding or getting rid of products that can no longer be used or repurposed.

      The study also considers the moderating role of two factors:
      - Regulatory Pressure: The influence of government regulations and policies on how companies engage in reverse logistics activities.
      - Ownership Pressure: The pressure from stakeholders, shareholders, or owners of the company to adopt and implement certain reverse logistics strategies.
      The study uses survey data collected from managers at 89 ISO14001 certified electrical and electronic equipment manufacturing firms. Regression models are used to test various hypothesized relationships.

      In summary, this research explores the impact of different reverse logistics disposition options on environmental performance, profitability, and sales growth in the context of green supply chain management. It also examines the moderating effects of regulatory and ownership pressures on these relationships, providing insights that can inform business decisions and the implementation of reverse logistics strategies.

      PDF: Welcome to this informative PDF file on the contingent role of institutional pressure in reverse logistics in Malaysia! This study provides valuable insights into the effects of disposition options on environmental performance, profitability, and sales growth.

      Example questions:
      1. What are the five disposition options for reverse logistics, and how do they impact environmental performance?
      2. How does institutional pressure influence the adoption of extended producer responsibility in Malaysia?
      3. Can this study's findings be applied to other countries with similar institutional contexts?

      Me: What are the five disposition options for reverse logistics, and how do they impact environmental performance?

      PDF: The five primary disposition options for reverse logistics are repair, recondition, remanufacture, recycle, and disposal. The study examines the relationship between each option and measures of performance in terms of environmental performance, profitability, and sales growth. The study hypothesizes that the employment of these disposition options is positively related to measures of performance. However, the specific impact of each option on environmental performance is not explicitly stated in the given texts. Me: How does institutional pressure influence the adoption of extended producer responsibility in Malaysia?


      PDF: The lack of reverse logistics programs promoting product reuse initiatives in Malaysia suggests that the competition for recoverable assets is low and green consumerism has yet to permeate sociocultural systems. The model developed in the study excludes mimetic and normative pressure as institutional forces because only a very small number of firms in Malaysia have committed to product reprocessing, and the environmental sentiment of Malaysian consumers has yet to develop to a point where reclamation of EEE products might be seen as a requirement or anticipated norm. Therefore, the study suggests that regulatory and ownership pressures affect organization-wide commitment to product recovery activities. Me: Can this study's findings be applied to other countries with similar institutional contexts?


      PDF: The study's findings may be applicable to other countries with similar institutional contexts, particularly those in East Asia. The study notes that the development of regulatory policy is important to promoting producers' involvement in pollution prevention initiatives. Examples of electronic waste and/or recycling regulations in East Asian countries, such as Japan's Home Appliances Recycling Law of 1998 and Promotion of Effective Utilization of Resources Law of 2001, Korea's Extended Producer Responsibility in Recycling Law of 2003, and Taiwan's Waste Disposal Act of 1998, may serve as models for other countries. Additionally, investigating the influence of leading firms in requiring their pool of suppliers to comply with stricter regulations would assist sustainable supply chain management. However, it is important to note that the specific institutional contexts of each country may differ, and thus the findings may not be directly transferable without further research.

      Introduction of the paper:
      Globalization and the advancement of information infrastructures have raised concerns about environmental and human health issues caused by mismanagement of electrical and electronic equipment (EEE) waste.
      The consumption rates of EEE have increased, leading to the need for manufacturers to take responsibility for collecting and properly disposing of products.
      Malaysia, like other industrialized countries, has witnessed the growth of environmentally conscious practices, with EEE accounting for a significant value in manufacturing exports.
      The introduction of governmental policies and guidelines, such as the "Guidelines for the Classification of Used Electrical and Electronic Equipment in Malaysia," aims to control the transboundary movement of e-waste and promote lifecycle stewardship.
      Reverse logistics plays a crucial role in the recoverability of product returns and the proper disposition of products. It involves activities such as repair, recondition, remanufacture, recycle, and disposal.[1]
      The paper aims to examine the effects of using each reverse logistics disposition option on environmental performance, profitability, and sales growth, while also considering the moderating role of institutional pressures.[2][1]

      Literature survey of this paper:

      Globalization and the advancement of information infrastructures have raised concerns about environmental and human health issues caused by mismanagement of electrical and electronic equipment (EEE) waste .
      The rising concern about transboundary movement of waste has encouraged the introduction of a new governmental policy entitled "Guidelines for the Classification of Used Electrical and Electronic Equipment in Malaysia" to control and restrict the exportation of e-waste .
      Previous work in the areas of closed-loop supply chains, green supply chains, reverse logistics, and environmental management has identified five commonly adopted product disposition options: repair, recondition, remanufacture, recycle, and disposal .
      Reverse logistics facilitates the recoverability of product returns and is a key component of the process .
      Manufacturers are encouraged to shift from reactive approaches to pollution prevention to more proactive approaches that promote lifecycle stewardship and higher yields of recoverable products . Legislative requirements, such as extended producer responsibility, have been introduced to encourage collection and recovery of end-of-use products .
      Firms face negative environmental publicity and non-compliance costs if proper reverse logistics processes are not established and followed .
      The profitability of product disposition activities is promising when accompanied by well-planned strategies, as remanufactured or reclaimed products have lower costs .
      It is important for firms to understand the implications of designing reverse logistics services . This research contributes to the reverse logistics performance literature by examining the performance outcomes of reverse logistics product disposition options and investigating the effects of institutional pressures on these relationships [1].

      Methods used in this paper:
      The paper utilizes survey data collected from managers at 89 ISO14001 certified electrical and electronic equipment manufacturing firms in Malaysia .
      Regression models are employed to test a series of hypothesized relationships between reverse logistics disposition options and measures of performance, as well as the moderating role of institutional pressures .
      The study considers both regulatory pressure and ownership pressure as forms of institutional pressure [1].
      The hypothesized model is presented in a figure, illustrating the relationships between reverse logistics disposition options, institutional pressures, and performance measures . The number of employees is used as a control variable in the research to account for firm size and resource availability .
      Interaction terms are examined to explore the combined effects of different reverse logistics disposition options on performance .

      The survey was administered to these firms, targeting the managers responsible for Environmental, Health, and Safety and/or ISO14001 compliance .
      The sampling frame for the study was obtained from the FMM-MATRADE Industry Directory for Electrical and Electronics 2007-2008, from which 177 organizations were chosen .
      Out of the 98 usable responses received, nine respondents were excluded from analysis as their organizations do not implement reverse logistics practices, resulting in a final sample size of 89 . The survey package was personalized and participants had the choice to return the survey through conventional mail or electronic mail .
      The data collected from the survey was used to test a series of hypothesized relationships through regression models [1].

      Results of the paper:
      The study found that the use of different reverse logistics disposition options had varying effects on measures of performance. The recovery of valuable components during product recondition and remanufacture activities contributed to enhanced environmental and economic benefits. Product recycling and disposal activities were not necessarily performance-inducing initiatives in the face of regulatory pressures. The presence of institutional pressure, specifically regulatory pressure, influenced the relationship between reverse logistics disposition options and performance measures. Repair, recycle, and disposal options were found to evoke higher measures of performance when regulatory pressure was included. The results highlight the importance of regulatory policies in promoting producers' involvement in pollution prevention initiatives. The findings suggest that legislative frameworks regarding extended producer responsibility are recommended to motivate the implementation of reverse logistics product disposition activities. [1][2].

      Legislative frameworks regarding extended producer responsibility are recommended to motivate the implementation of reverse logistics product disposition activities. [1][2].

      Limitations of this paper:
      The study only focused on ISO14001 certified electrical and electronic equipment manufacturing firms, which may limit the generalizability of the findings to other industries or firms with different environmental management qualifications.
      The study did not investigate the influence of other components of reverse logistics management, such as reverse logistics information technology capabilities and innovation capabilities, as well as product acquisition, transportation and inventory management, and distribution and sales. Future studies could explore these aspects to provide a more comprehensive understanding of reverse logistics performance.
      The study did not consider other components of institutional pressure, such as normative and mimetic pressure, which could further explain the framework under study. Including these components in future research could provide a more nuanced understanding of the relationship between institutional pressure and reverse logistics performance.
      The study relied on survey data, which may be subject to response bias or limited by the participants' perspectives. Future research could consider using case study research design, such as semi-structured interviews or focus groups, to obtain more in-depth information on the challenges of implementing reverse logistics management.
      The study suggested that knowledge diffusion from leading manufacturers in developed countries could be a valuable resource for sustainable supply chain management. However, the study did not explore this aspect in detail. Future research could investigate the influence of leading firms in requiring their suppliers to comply with stricter regulations. [1].

      Future works suggested in this paper:
      Future studies should investigate the influence of other components of reverse logistics management on performance measures, such as reverse logistics information technology capabilities, innovation capabilities, product acquisition, transportation and inventory management, and distribution and sales.
      Further research could explore the impact of normative and mimetic pressure as additional components of institutional pressure on reverse logistics performance.
      It is recommended to examine the knowledge diffusion of leading manufacturers from developed countries, particularly those that have progressed beyond legislative requirements, as a valuable resource for reverse logistics management[1].
      Future studies could also consider the implementation of legislative frameworks regarding extended producer responsibility to motivate the adoption and use of reverse logistics strategies. Case study research design, such as semi-structured interviews or focus groups, could be employed to gain more in-depth insights into the challenges and benefits of implementing reverse logistics management[2].


      Bing: 企業永續與社會責任是一個涉及企業在經營過程中對環境、社會和治理的影響和責任的概念,它包含了許多不同的觀念和學說,例如ESG、CSR、SDGs等。

      • 1999-CSR 是企業社會責任(Corporate Social Responsibility)的縮寫,它是聯合國在1999年所提出的廣泛概念,主要講述到企業在營利的同時也要顧及到道德規範、改善員工、社會生活品質等。CSR是企業主動承擔的責任,而ESG更像是投資人對企業評鑑的標準,以及達成SDGs永續目標的手段-1, [永續發展]
      • 2004-ESG 是環境(Environment)、社會(Social)和公司治理(Governance)三個關鍵字的縮寫,它是一種用來評估企業永續發展能力和風險管理能力的指標,也是投資人用來評估企業長期價值和財務表現的標準。ESG的概念最初被提出,可以回溯到2004年聯合國當時發佈一份《Who Cares Wins》報告,裡面提到ESG適用在企業在投資決策和風險管理流程的評估策略-1, [ESG懶人包]
      • 2015-SDGs 是永續發展目標(Sustainable Development Goals)的縮寫,它是聯合國在2015年制定的17項目標,涵蓋了169項細項目標,期望在2030年實現全球永續。SDGs不只在企業管理和投資,更關注全球社會和環境議題,強調了消除貧窮、減緩氣候變遷、促進性別平權、健康福祉、教育平等、能源轉型、氣候行動等議題

      目前的情況是,隨著全球面臨氣候危機、社會不平等、公共衛生等挑戰,越來越多的企業意識到需要實踐永續與社會責任,並將其納入營運策略和風險管理中。同時,越來越多的投資人也重視ESG表現,並將其作為投資決策的重要依據。此外,許多國家和地區也制定了相關的法規和政策,要求企業揭露非財務資訊,例如減碳目標、供應鏈管理、員工福利等。因此,企業永續與社會責任已成為當代商業世界不可或缺的一部分。

    1. This empirical study focuses on the field of reverse logistics within the context of green supply chain management. It examines the effects of five commonly adopted disposition options (repair, recondition, remanufacture, recycle, and disposal) on measures of environmental performance, profitability, and sales growth. The study also investigates the moderating role of regulatory and ownership pressures on the relationship between each disposition option and performance levels.

    five of the most frequently adopted product disposition options as repair, recondition, remanufacture, recycle, and disposal
    p.97
    repair: fixing or replacing malfunctioning components or modules in order to restore the existing product to working order.
    Recondition: a higher order option than repair in that some level of product disassembly in order to restore the existing used product to specified working conditions is required.
    Remanufacture: a higher order option than recondition and is the process of restoring used products to at least original equipment manufacturer (OEM) performance specifications (Neto et al., 2016).

    Recycling: extracting reusable materials from used products or components and includes collecting, shredding, sorting and processing material for reuse in new products.
    Disposal: the process of properly landfilling or incinerating parts or products. This option is typically chosen on the condition that other disposition options are seen as too complex or cannot be made beneficial due to, perhaps, a lack of market options.

    Functionability: repair<1; Recondition<=1; Remanufacture=>1;
    Profitability: Recycling>0; Disposal<0;

  • • procedural isomorphism是一個社會學的概念,指的是不同的組織或機構在面對相似的環境或壓力時,會採取相同或類似的程序或規則來適應和合法化,從而使得它們的結構和行為趨於同質化。這個概念來自新制度主義理論,它認為組織或機構不僅受到效率或效益的驅動,也受到制度環境的影響,例如法律、政策、文化、規範等
    舉例來說,許多大學在面對全球化和競爭的壓力時,會採取相同或類似的程序或規則來提升自己的聲譽和排名,例如建立國際合作關係、發表高水平的學術論文、招收優秀的教師和學生等。這些程序或規則可能並不符合每個大學的特色或使命,但卻是被普遍認可和接受的做法,因此大學會遵循這些做法來適應和合法化自己的存在。

  • •Theory#1 Institutional theory 是一種用來研究組織和社會現象的理論,它的核心概念是制度,即那些規範和影響個體和集體行為的規則、規範、信念和價值觀。此理論認為,組織和社會不僅受到物質和技術的制約,還受到制度環境的影響,即那些來自政府、法律、文化、專業團體等的壓力和期待。理論試圖解釋組織和社會如何形成、變遷和適應制度環境,以及制度環境如何塑造組織和社會的結構、文化和行為
    Institutional theory有不同的流派和分支,例如社會學制度主義、理性選擇制度主義、歷史制度主義、規範制度主義等。這些流派在對制度的定義、形成、變遷、影響等方面有不同的假設和觀點。例如,社會學制度主義強調制度是一種意義系統,影響個體的認知模式和身份認同;理性選擇制度主義強調制度是一種約束系統,影響個體的利益計算和策略選擇;歷史制度主義強調制度是一種路徑依賴的過程,影響個體的歷史記憶和行動能力;規範制度主義強調制度是一種規範系統,影響個體的道德判斷[和行為準則]](https://zhuanlan.zhihu.com/p/92152800)。
    這個Theory廣泛應用於管理學、政治學、社會學等領域的理論,它可以幫助我們理解組織和社會中存在的各種現象,例如組織變革、組織學習、組織文化、領導風格、政策制定、政治競爭、社會運動等。如果您想要更多的細節,您可以參考以下的連結:

      為防偏差 • 關於Harman’s one factor test是一種用來檢測共同方法偏差的統計方法,共同方法偏差是指在行為研究中,使用相同的方法(例如問卷調查)來測量自變數和因變數時,可能產生的系統性誤差或偏見。檢驗的基本假設是,如果共同方法偏差存在,那麼在對所有變數進行因素分析時,會得到一個主要的因子,或者一個因子能夠解釋大部分的變異。通常,如果第一個因子能夠解釋超過40%的變異,就認為存在嚴重的共同方法偏差
      舉例來說,如果一個研究想要探討員工的工作滿意度和組織承諾對工作績效的影響,並且使用問卷來測量這些變數,那麼就有可能產生共同方法偏差,因為問卷可能會引起員工的社會期望效應、回答傾向、記憶錯誤等。為了檢測這種偏差,可以使用Harman’s one factor test,將所有變數放入因素分析中,看是否只有一個因子或第一個因子的方差貢獻率很高。如果是這樣,就表示共同方法偏差影響了研究結果的有效性和可信度

    Presentation準備

  • Sld.1: Contingent role
  • 所謂Contingent role是指一種臨時或非正式的工作角色,通常由臨時工作者或外包工作者來執行。臨時工作者或外包工作者是指公司聘請的個人,代表其執行角色或專案式工作,而非傳統員工。其可能包括獨立承包商、顧問、自由工作者、臨時或其他外包勞工 (例如零工)
    Contingent role的特點是:
  • 它是根據公司的需求或情況而變動的,而不是固定或長期的。
  • 它是基於合約或協議而非雇傭關係而建立的,因此不享有傳統員工的權利或福利。
  • 它是以完成特定的任務或目標為導向的,而不是以時間或地點為限制的。
  • 它是以技能或專業知識為基礎的,而不是以職位或階級為標準的。
    Contingent role的優點和缺點是:
  • 對於公司來說,採用Contingent role可以節省成本、增加彈性、引進新技術或創意、應對市場變化等。
  • 對於臨時工作者或外包工作者來說,從事Contingent role可以提高收入、增加自主性、拓展網絡、學習新技能等。
  • 但同時,Contingent role也存在一些挑戰和風險,例如管理困難、溝通障礙、質量控制、法律問題、安全保障等。

  • Sld.6: 在論文3.2. Control variable說
      這說法的意思是,根據一個數據集的分析結果,作者計算了後設效力(post-hoc power),也就是在已知實際效果大小的情況下,檢驗假設的能力。作者使用了一個完整的模型,包含14個預測變量,並且得到了一個R方值(R-square value)為0.357,表示模型可以解釋數據變異的35.7%。作者還設定了顯著水平(alpha value)為0.05,也就是容許5%的錯誤拒絕真實的零假設的機率。在這些條件下,作者發現樣本數(sample size)為89時,後設效力(post-hoc power)為0.997,表示如果零假設是錯誤的,那麼有99.7%的機率能夠拒絕它,也就是有99.7%的機率能夠發現實際效果。
      Based on the analysis of a dataset, the author calculated the post-hoc power, which is the ability to test a hypothesis when the actual effect size is known. The author used a comprehensive model that includes 14 predictor variables and obtained an R-square value of 0.357, indicating that the model can explain 35.7% of the data's variance. The author also set the significance level (alpha value) at 0.05, meaning there's a 5% probability of incorrectly rejecting the true null hypothesis. Under these conditions, the author found that with a sample size of 89, the post-hoc power is 0.997. This implies that if the null hypothesis is false, there's a 99.7% probability of rejecting it, or in other words, a 99.7% chance of detecting the actual effect.

      關於後設效力分析可參考Post hoc power analysisis it an informative and meaningful analysis? 這篇文章詳細介紹了後設效力分析的原理和問題,並且提供了一些模擬實驗來說明其缺陷。
      還有What is the post-hoc power in my experiment? How to calculate this?這個問答網站上有一個關於後設效力分析的問題和回答,其中包含了一些用R語言進行計算的代碼和解釋。
      還有Post Hoc Power: Tables and Commentary這篇文章提供了一些常見的t檢驗和F檢驗的後設效力表格,並且對其進行了評論和建議
      Post-hoc power analysis是「事後功效分析」,這是在收集和分析數據之後進行的功效分析。
      以下是分析的解釋:
      - 全模型的R-square值為.357:這表示模型解釋的變異量是35.7%。R-square(確定系數)是回歸模型中的一個常用統計量,它表示模型解釋的資料中總變異的比例。例如,R-square值為0.357意味著模型解釋了35.7%的資料變異,而剩餘的64.3%的變異由其他未在模型中的因子解釋。
      alpha值為0.05:alpha值(或稱為顯著性水平)是用來評估統計結果是否具有統計顯著性的臨界值。當p值(概率值)小於或等於alpha值時,我們認為結果是統計顯著的。在這裡,alpha值為0.05,這是最常用的臨界值,表示有5%的風險誤判真實的效應為零。 - 14個預測因子:這意味著該回歸模型中有14個獨立變量或預測因子。
      - 樣本大小為89:這是研究中的參與者數量。
      - 功效為0.997:功效分析是用來確定一項研究有多大的概率能夠正確地檢測到一個實際存在的效應。在此情況下,功效為0.997,這意味著如果實際存在一個效應,這項研究有99.7%的概率能夠正確地檢測到它。這是一個非常高的功效值,表示該研究有很大的能力檢測到效應,如果它真的存在。
      總結:這段文字表示,考慮到給定的R-square值、alpha值和預測因子數,對89個樣本進行的分析具有非常高的功效(99.7%),這意味著該研究在檢測效應時具有很大的能力。

  • Sld.9 關於Four-step hierarchical regression analyses
    • 是一種多元迴歸分析的方法,它的特點是將預測變數分成四個區塊,按照一定的順序逐步加入迴歸模型中,以檢驗每個區塊對依變數y的影響和貢獻。這種方法可以幫助研究者控制一些可能影響結果的變數,並且測試一些理論假設或假說
      舉例來說,如果一個研究想要探討工作壓力、工作滿意度和組織承諾對員工離職意圖的影響,並且想要控制員工的年齡、性別和教育程度等背景變數,那麼可以使用Four-step hierarchical regression analyses來進行分析。具體的步驟如下:
      • 第一步:將背景變數(年齡、性別和教育程度)作為第一個區塊,加入迴歸模型中,計算其對離職意圖的解釋量(R square)和顯著性(F change)。
      • 第二步:將工作壓力作為第二個區塊,加入迴歸模型中,計算其對離職意圖的解釋增加量(R square change)和顯著性(F change)。
      • 第三步:將工作滿意度作為第三個區塊,加入迴歸模型中,計算其對離職意圖的解釋增加量(R square change)和顯著性(F change)。
      • 第四步:將組織承諾作為第四個區塊,加入迴歸模型中,計算其對離職意圖的解釋增加量(R square change)和顯著性(F change)。
      通過這種方法,研究者可以比較不同區塊對離職意圖的影響大小和方向,並且檢驗是否符合預期或假設。例如,如果發現工作壓力對離職意圖有正向的顯著影響,而工作滿意度和組織承諾有負向的顯著影響,那麼就可以說明這些變數與離職意圖有因果關係。如果發現背景變數對離職意圖沒有顯著影響,那麼就可以說明這些變數不會干擾或混淆其他變數的效果2
  • Sld.12
    做Regression analysis迴歸分析時F Change、R^2及Durbin-Watson是三個常用的統計指標,用來評估迴歸模型的適合度和假設檢驗。
    • • F Change是指在多元迴歸分析中,每增加一個自變數時,迴歸模型的F統計值的變化量。F統計值是用來檢驗迴歸模型是否顯著,也就是自變數是否能有效地解釋依變數的變異。F Change越大,表示增加的自變數對模型的貢獻越大;反之,F Change越小,表示增加的自變數對模型的貢獻越小
      • R2是指判定係數,也就是迴歸模型可以解釋依變數變異的比例。R2越接近1,表示迴歸模型的適合度越高,自變數對依變數的影響越大;反之,R^2越接近0,表示迴歸模型的適合度越低,自變數對依變數的影響越小
      • Durbin-Watson是指用來檢驗迴歸模型殘差是否具有自相關性的統計值。自相關性是指殘差之間是否存在相互影響或依賴的關係。Durbin-Watson的值介於0到4之間,越接近2表示殘差沒有自相關性,迴歸模型符合獨立性的假設;越接近0或4表示殘差具有正或負的自相關性,迴歸模型不符合獨立性的假設

    1.About the paper: Reverse Logistics in Malaysia
    ChatPDF20230916: please give me a summary this paper within 2000 words
  • This paper examines the contingent role of institutional pressure in reverse logistics in Malaysia. Reverse logistics refers to the process of managing the return of products from consumers to manufacturers or retailers. The study aims to investigate the effects of disposition options on environmental performance, profitability, and sales growth. The research design is a cross-sectional survey of 150 ISO14001 certified electrical and electronic equipment (EEE) manufacturing firms enlisted with the Federation of Malaysian Manufacturers (FMM) and the Malaysia External Trade Development Corporation (MATRADE). The data were analyzed using partial least squares structural equation modeling (PLS-SEM).

  • The study is motivated by the growing concern about the environmental impact of EEE waste. EEE waste contains hazardous materials that can harm the environment and human health if not properly managed. Therefore, many countries have introduced regulations to encourage firms to adopt environmentally friendly practices such as extended producer responsibility (EPR). EPR is a policy approach that requires manufacturers to take responsibility for the entire life cycle of their products, including their disposal and recycling.

  • The study contributes to the literature by providing empirical evidence on the contingent role of institutional pressure in reverse logistics. Institutional pressure refers to the influence of external actors such as regulators, customers, and competitors on firms' behavior. The study examines the effects of three types of institutional pressure on the relationship between disposition options and measures of performance. The three types of institutional pressure are coercive pressure, mimetic pressure, and normative pressure.

  • The results show that the adoption of EPR is positively associated with environmental performance, profitability, and sales growth. The findings also reveal that institutional pressure moderates the relationship between disposition options and environmental performance. Specifically, coercive pressure strengthens the positive effect of EPR on environmental performance, while mimetic pressure weakens the positive effect of recycling on environmental performance. Furthermore, normative pressure enhances the positive effect of refurbishing on environmental performance.

  • The study has several implications for theory and practice. Theoretically, the study contributes to the literature on institutional theory and reverse logistics. The findings suggest that institutional pressure is an important factor that moderates the relationship between disposition options and measures of performance. The study also highlights the importance of considering the institutional context when examining the effects of reverse logistics on measures of performance.

  • Practically, the study has implications for firms, policymakers, and regulators. For firms, the study suggests that they should adopt EPR as a disposition option to improve their environmental performance, profitability, and sales growth. Moreover, firms should consider the institutional pressure they face when selecting disposition options for their products.
