We provide an exact myopic analysis for an N‐stage serial inventory system with batch ordering, linear ordering costs, and nonstationary demands under a finite planning horizon. We characterize the optimality conditions of the myopic nested batching newsvendor (NBN) policy and the myopic independent batching newsvendor (IBN) policy, which is a single‐stage approximation. We show that echelon reorder levels under the NBN policy are upper bounds of the counterparts under both the optimal policy and the IBN policy. In particular, we find that the IBN policy has bounded deviations from the optimal policy. We further extend our results to systems with martingale model of forecast evolution (MMFE) and advance demand information. Moreover, we provide a recursive computing procedure and optimality conditions for both heuristics which dramatically reduces computational complexity. We also find that the NBN problem under the MMFE faced by one stage has one more dimension for the forecast demand than the one faced by its downstream stage and that the NBN policy is optimal for systems with advance demand information and stationary problem data. Numerical studies demonstrate that the IBN policy outperforms on average the NBN policy over all tested instances when their optimality conditions are violated. 相似文献

ABSTRACTMalaysia is one of the multi-ethnic, multi-cultural and multi-religious countries in Southeast Asia. Due to the pluralistic nature of Malaysia, it has a political structure based on ethnic politics. The ethnic preferential policies affected most domains of this country. The objective of this article is to examine the origin and background of ethnic politics in Malaysia. Findings of this study indicate that, ethnic politics originated during the British colonial period, it became a tool used by the Barisan Nasional for the legitimacy of regime. Moreover, ethnic politics in Malaysia today is intertwined with religion. Besides, there is the dilemma of the choice between the interest of certain ethnic group and national interests. However, with the opposition coalition Pakatan Harapan won the election in 9th May, UMNO-led BN lost power and interrupted its 61 years control, which leaves us an interesting topic to think about the future of Malaysian ethnic politics. 相似文献

Most orphaned children in China are cared for by their extended families or become state wards under the guardianship of child welfare institutions. Some exceptions are children who are found and cared for by families in the community, without a formalized adoption or foster relationship. In some locations, institutions now accept guardianship for these children and support the informal adoptive family to continue to care for them. This article examines the outcomes for these children as they became young adults by comparing these 12 children raised within the system as they approach or have approached young adulthood (now aged 16–40 years-old). Some of the participants were either informally adopted or lived in institutional care. The results of this study found that the family environment was more conducive to the young people’s wellbeing as they approached or entered adulthood. The participants raised in informal care appeared to be treated similar to the biological children in these families. When the institution formalized the state guardianship responsibility, it also meant the families had state resources for support to protect the children’s rights to economic security, education, health care, and social participation. This practice by the institution supported the addition of informal adoption, as one step closer to permanency than foster care. Future implications include considering this option to help promote the family system assisting these children, families, and the state. 相似文献

Debates in international forums and in mainstream media on the role, responsibility, liability, and response of ecclesiastical authorities of the Roman Catholic Church (RCC) toward clerical child sexual abuse (cCSA) fail to take into account the historical roots and awareness of the problem. Reports also fail to mention the historic organizational laws RCC developed over centuries. In contrast, RCC documents evidence that the Catholic Church not only carried century’s old history of cCSA, but also repeatedly condemned cCSA by successive papal authorities, organizational laws, and institutional management mechanisms. During the first millennium, however, church laws remained confined to the bookshelves and were not converted into appropriate management policies and infrastructural models. This was largely due to the absence of a central administrative organizational structure, which developed later in the 12th century, following the Second Council of Lateran (1139) when the Papacy asserted its authority to establish administrative control over the organizational church. It was only then that management policies started to be framed and institutional structures enacted to deal more appropriately with cCSA from the 14th to 20th centuries. Despite this, RCC developed a culture of secrecy using clandestine organizational management models and institutional laws prescribed in 1568, 1622, 1741, 1866, 1922, and 1962 which aimed to manage cCSA. The current study traces reported cCSA as far back as the first century and critically examines the organizational laws, and institutional policies developed by RCC to address clerical sexual misconduct up to the end of the 19th century. 相似文献

We use organizational justice theory to examine how perceptions of fairness affect the decision‐making process of line managers. In‐depth interviews were conducted with 35 Irish managers to explore how managers make organizational allocation decisions in cases where it is impractical to offer work–life balance accommodations to all employees. The findings suggest that firstly, managers construct the ‘life’ aspect of work–life balance within a heteronormative framework, where the emphasis is on caregiving and most usually parenting. Secondly, managers actively use their decision‐making powers around both formal and informal work–life balance supports to minimize injustice within their departments. By bringing together ideas about organizational justice and managerial decision‐making, we indicate how managers determine fairness through a decision‐making process narrowed by embedded gender role beliefs. Implications for future research and practice are discussed. 相似文献
