These models usually have as objective the minimizing of inventory costs. In this research work we propose a mathematical model of an inventory system with time-dependent three-parameter Weibull deterioration and a stochastic type demand in the form of a negative exponential distribution. Explicit expressions for the optimal values of the decision variables are obtained. Numerical examples are provided to illustrate the theoretical development.展开更多

This is so when deterioration of units in the inventory is subject to constant deterioration rate, demand rate is quadratic function of time and salvage value is associated with the deteriorated units. Shortages in the system are not allowed to occur. A mathematical formulation is developed when the supplier offers a permissible delay period to the customers under two circumstances: 1) when delay period is less than the cycle of time;and 2) when delay period is greater than the cycle of time. The method is suitable for the items like state-of-the-art aircrafts, super computers, laptops, android mobiles, seasonal items and machines and their spare parts. A solution procedure algorithm is given for finding the optimal order quantity which minimizes the total cost of an inventory system. The article includes numerical examples to support the effectiveness of the developed model. Finally, sensitivity analysis on some parameters on optimal solution is provided.展开更多

Therefore, business firms may classify the arbitrary items using the option that would maximize their own interest. This reduces the comparability of financial statements amongst business firms. This study aims to investigate the factors explaining management preferences in the selection of financial reporting practices on the arbitrary cash flow items. It concludes that managers tend to magnify the CFO reported in order to maximize the shareholders＇ wealth, which in turn would maximize their compensation. Managers of business firms with a relatively smaller size of CFO tend to classify interest paid and dividends paid as non-CFO in order to magnify their CFO. They also tend to classify interest received as CFO in order to inflate their relatively smaller size of CFO up to expectation. Similarly, managers of business firms with a relative larger size of dividends paid would classify the dividends paid outside CFO.展开更多

Nevertheless, the analysis for finding an economic lot size has based on a number of unrealistic assumptions. A common unrealistic assumption in using EPQ is that all units produced are of good quali ty. The classical EPQ model shows that the optimal lot size will generate minimum ma nufacturing cost, thus producing minimum setup cost and inventory cost. However, this is only true if all products manufactured in the process are assumed to be of good quality (i.e. all products are within the specification limits). In rea lity this is not the case, therefore, it is necessary to consider the cost of im perfect quality items, because this cost can influence the economic lot size. Ma ny studies and recent papers have indicated that there is a significant relation ship between economic production lot size and process/product quality. However, their models included either the imperfect quality items (not necessarily de fective) which are to be sold at a discounted price or defective items which can be reworked or rejected. The aim of this paper is to provide a framework to integrate three different sit uations (discounted pricing/rework/reject) into a single model. 100% inspection is performed in order to distinguish the amount of good quality items, imper fect quality items and defective items in each lot. In this paper, a mathematica l model is developed, and a numerical example is presented to illustrate the sol ution procedures. It is found that the economic production lot size tends to inc rease as the average percentage of imperfect quality items and defectives (rejec ted items) increases.展开更多

[Phys. Rev. Lett.113 210501(2014)] claimed that the quadratic speedup over classical algorithms has been achieved. However, in this paper, we point out that this is not the case, because the query complexity of Yoder’s algorithm is actually in O(1/λ01/2)rather than O(1/λ1/2), where λ0 is a known lower bound of λ.(ii) In terms of the trail-and-error method, currently the algorithm without randomness has to take more than 1 times queries or iterations than the algorithm with randomly selected parameters. For the above problems, we provide the first hybrid quantum search algorithm based on the fixed-point and trail-and-error methods, where the matched multiphase Grover operations are trialed multiple times and the number of iterations increases exponentially along with the number of trials. The upper bound of expected queries as well as the optimal parameters are derived. Compared with Yoder’s algorithm, the query complexity of our algorithm indeed achieves the optimal scaling in λ for quantum search, which reconfirms the practicality of the fixed-point method. In addition, our algorithm also does not contain randomness, and compared with the existing deterministic algorithm, the query complexity can be reduced by about 1/3. Our work provides a new idea for the research on fixed-point and trial-and-error quantum search.展开更多

However, there is insufficient evidence regarding effective integrated community-based care. In particular, few studies have focused on social aspects of the community environment related to elderly health. This study aimed to consider social aspects as evaluation items, focusing particularly on social determinants from the perspective of community-dwelling people, to explore truly effective integrated community-based care to improve elderly health. The definition of social determinants means social cohesion in social and community contexts. A literature review of English articles published in peer-reviewed journals up to October 2019 was conducted using PubMed, MEDLINE, and CINAHL with the following search terms: “social cohesion,” “elderly health,” “mental health” and “community.” Identified articles were screened based on title and abstract, and selected articles were subjected to full-text assessment and critical review. All references cited in the selected articles were also reviewed. The following inclusion criteria were used: 1) studies targeting community-dwelling elderly people or community-dwelling people including elderly people as participants;2) studies with clear descriptions of social factors in the Methods section;and 3) studies with clear descriptions of health-related items in the Methods section. From the 21 articles analyzed, of which 9 articles defined social determinants as social cohesion in social and community context, 37 items were extracted as social aspects at the community level that reflect the perspective of residents. These items can be developed as evaluation items for community-based health care outcomes through consensus among community health care providers and further investigation.展开更多

The transportation modes are full container load (FCL) and less than container load (LCL). Deteriorating items, such as specialty gases which are applied in semiconductor fabrication, deteriorate owing to environmental variation. Exact algorithms are proposed to determine the optimal inventory policies over a finite and an infinite planning horizon. Numerical examples are given to illustrate the proposed solution procedures. In addition, when the deterioration rate is large, the results of the proposed model perform better compared to the inventory model proposed by Rieksts and Ventura (2008).展开更多

This research article deals with analysis of evaluation data collected regarding humanities course from a College of Commerce & Economics, Mumbai, Maharashtra, India, on Likert type items. Appropriateness of one parametric measure and three non-parametric measures are discussed and used in this regard which could provide useful clues for educational policy planners. Keeping in view of the analytical results using these four measures, regardless of the threshold regarding satisfaction among students, overall performance of almost every subject has been un-satisfactory. There is a need to make a focused approach to take every course at the level of high performance. The inconsistency noticed under every threshold further revealed that under such poorly performing subjects globally, one needs to analyze merely at the global level item. Once the global level analysis reveals high performance of a course, then only item specific analysis may need to be focused to find out the items requiring further improvements.展开更多

The market demand is assumed to be level dependent linear type. The model has also considered the constant production rate which stops after a desired level of inventories and that is the highest level of it. Due to the market demand, defective item and product’s decay, the inventory reduces to the zero level where again the production cycle starts. With a numerical search procedure</span><span style="font-size:12px;font-family:Verdana;">,</span><span style="font-size:12px;font-family:Verdana;"> the proof of the proposed model has been shown.

The (SATS-36), which consists of 36 5-point Likert Scale items, was used to actually achieve the goal of this study. Furthermore, the researchers developed three forms, each with a different set of extra negative items (2, 4, and 6). The three forms were distributed to a sample of (750) students at Yarmouk University. The results revealed that form 1, which enclosed 6 extra negative items, had the lowest detected rate of insufficient effort responses (IERs) (7.20%), while form 3, which contained 2 extra negative items, had the highest detection rate (15.6%). The detection rate was discovered respectively among the Lie Detection Scale, Mahalanobois, l<sup>p</sup>z</sub> and the method of extra negative items. The highest detection rate was found in form 3 with two extra negative items, and data reliability decreased after the insufficient effort responses were removed (IERs). Furthermore, the results showed that the maximum changes in model-data fit indices after data filtering were in form 3, which contained two extra negative items. Moreover, the results indicate that the reliability of data after filtering those with insufficient effort responses (IERs) is reduced.展开更多

The transportation modes are full container load (FCL) and less than container load (LCL).

Exact algorithms are proposed to determine the optimal inventory policies over a finite and an infinite planning horizon. Numerical examples are given to illustrate the proposed solution procedures. In addition, when the deterioration rate is large, the results of the proposed model perform better compared to the inventory model proposed by Rieksts and Ventura (2008).

The market demand is assumed to be level dependent linear type. The model has also considered the constant production rate which stops after a desired level of inventories and that is the highest level of it. Due to the market demand, defective item and product’s decay, the inventory reduces to the zero level where again the production cycle starts. With a numerical search procedure</span><span style="font-size:12px;font-family:Verdana;">,</span><span style="font-size:12px;font-family:Verdana;"> the proof of the proposed model has been shown. The objective of the proposed model is to find out the total optimum inventory cost, optimum ordering cost and optimum ordering cycle.
文摘This study attempted to determine the effectiveness of the number of extra negative items in identifying insufficient effort responses in Attitudes toward Statistics (SATS-36). The (SATS-36), which consists of 36 5-point Likert Scale items, was used to actually achieve the goal of this study. Furthermore, the researchers developed three forms, each with a different set of extra negative items (2, 4, and 6). The three forms were distributed to a sample of (750) students at Yarmouk University. The results revealed that form 1, which enclosed 6 extra negative items, had the lowest detected rate of insufficient effort responses (IERs) (7.20%), while form 3, which contained 2 extra negative items, had the highest detection rate (15.6%). The detection rate was discovered respectively among the Lie Detection Scale, Mahalanobois, l<sup>p</sup>z</sub> and the method of extra negative items. The highest detection rate was found in form 3 with two extra negative items, and data reliability decreased after the insufficient effort responses were removed (IERs). Furthermore, the results showed that the maximum changes in model-data fit indices after data filtering were in form 3, which contained two extra negative items. Moreover, the results indicate that the reliability of data after filtering those with insufficient effort responses (IERs) is reduced.

文摘Traditionally,‘morphemes’are consisting complex morphophonological properties and syntactic-semantic properties.However,in realizational theories such as Distributed Morphology,which is a syntactic approach to word formation,morphemes are abstract bundle of features without phonological properties,e.g.pl,fem,masc,categorizers(Embick,2015)etc.Nevertheless,when language assigns phonological properties to those features(namely late insertion),they serve as vocabulary items instead of morphemes.This was confirmed by Marantz(2000:15),who proposed that‘…we see,overtly,the vocabulary items,not the morphemes.’Moreover,morphemes are generative and there is no any bound morpheme,all are free(Hankamer&Mikkelsen,2018).Vocabulary items are not generative but expandable and visibly they can either be free or bound.So this paper intends to elaborate these issues together with evidence from Hausa.The entire paper is divided into following subsections:Introduction,Distributed Morphology,morphemes and vocabulary items in Hausa and their differences,followed by Conclusion remarks.
文摘The translation of culture-specific items(CSI)has been a challenge for translators as well as cited examples for untranslatability.With the analysis of the strategies employed on the Chinese-English translation of measurement unit by Howard Goldblatt in his translation works of different times,this paper discusses the transition from“untranslatable”to“translatable”of certain CSIs.Translation strategies for CSI are also proposed with the consideration of how Chinese culture being introduced into the outside world.The study shows that although Goldblatt clearly advocates“reader-centered”translation,that is,the translator should translate for the target language reader,and emphasizes that the translator can only translate and be responsible for the target language reader,we can still see his efforts to introduce Chinese culture to American readers through his translation.
