Order picking, which is collecting a set of products from different locations in a warehouse, has repeatedly been described as one of the most laborious and time-consuming internal logistic processes. Each order is issued to pick some products located at given locations in the warehouse. In this paper, we consider an order picking problem, in which a number of orders with different delivery due dates are going to be retrieved by a limited number of order pickers in multiperiods such that (...) the total tardiness is minimized. The aim is to determine a retrieval plan in terms of order batching and order picker multitrip routing as decision variables. Besides, products are arrived and replenished at the predetermined locations at different periods. Therefore, products sitting in those locations should be delivered soon to provide empty rooms for replenishment. A mixed integer linear programming formulation is proposed for this new problem. The model is optimally solved for small-size problems. For larger instances, grouping metaheuristic algorithms are proposed based on particle swarm optimization and the league championship algorithm that use group-based operators to generate reasonable batches of orders. Improvement heuristics are designed as well. The performance of the MILP formulation and metaheuristic algorithms is analyzed for different problem instances whose designs are based on real data gathered from an auto parts warehouse. Results indicate that our algorithms can stably solve large instances of the problem in a reasonable time. (shrink)

The study aimed to investigate whether work to family conflict experienced by employees of Kashan University of medical sciences differed from family to work conflict.A cross sectional study was carried out in 2014. A random sample of 202 employees in the four schools affiliated with Kashan University of medical (...) sciences located in central of Iran was selected and responded to items of the questionnaires using a 7-point Likert scale. Work-family conflict was measured using Carlson et al.’s 18 items scale. Higher values indicate higher levels of work to family conflict and family to work conflict. Analysis was carried out using SPSS 16.Employees experienced work-family conflict in the two directions. Work to family conflict with mean of 31.5510.68 was significantly (t=9.87, P. (shrink)

Background Many studies have investigated the adherence to professional codes of ethics by nurses. However, no study has explicitly examined the relationship between workload and adherence to professional codes of ethics among Iranian nurses. Objective This study aimed to explore the relationships between workload and adherence to professional codes of ethics among a sample of Iranian nurses. Materials and Methods A cross-sectional descriptive study was conducted on 213 nurses who were randomly selected from the different wards of Shahid Beheshti Hospital (...) of Kashan, Iran. Data collection instruments included a personal characteristics questionnaire, the Nursing Ethics Questionnaire, and the National Aeronautics and Space Administration Task Load Index. The Chi-square, the Spearman correlation coefficient, the Kruskal–Wallis, and Mann–Whitney U tests were used to analyze the data. Results A majority of nurses were females, married, and permanently employed. The mean of the overall perceived workload and adherence to professional codes of ethics were 76.36 ± 13.64 and 13.98 ± 2.58, that were at high and moderated level, respectively. Spearman correlation test showed no significant correlation between perceived workload and adherence to professional codes of ethics. A significant difference was found between the mean scores of adherence to professional codes of ethics in nurses working in different departments. Conclusion Participating nurses perceived high levels of workload but their mean adherence to professional codes of ethics was at a moderate level. The perceived workload was indirectly correlated with adherence to professional codes of ethics. (shrink)

Background:The holistic approach views the human as a bio-psycho-socio-spiritual being. Evidence suggests that among these dimensions, the spiritual one is largely ignored in healthcare settings.Objectives:This study aimed to evaluate Iranian nurses’ perceived professional competence in spiritual care, the relationship between perceived competence and nurses’ personal characteristics, and barriers to provide spiritual care.Research design:A cross-sectional study was conducted in the year 2014.Participants and research context:The study population consisted of nurses working in teaching hospitals in Kashan city. Using a stratified, systematic (...) random method, 250 samples were selected from a total of 1400 nurses. An indigenous instrument was used to assess the nurses’ competencies in spiritual care.Ethical considerations:A research ethics committee approved the study. All the participants were briefed on the study aims, were assured of the confidentiality of their personal information, and signed a written informed consent.Results:Among a total of 250 nurses, 239 answered the questionnaire completely, and in total, 23%, 51%, and 26% had poor, moderate, and favorable competence in spiritual care, respectively. No significant differences were found between the mean competence scores of spiritual care in terms of gender, marital status, employment status, and level of qualification. Significant difference was found between nurses’ overall score of competence in spiritual care and receiving training on spiritual care, nurses’ position, and the ward they worked in.Discussion:Confirming the findings of the international literature, this study puts light on the situation of nurses’ perceived competence and barriers to providing spiritual care in Iran as an eastern and Islamic context.Conclusion:Three-quarters of the nurses had moderate or unfavorable competence in spiritual care. Due to the crucial role of spiritual care in quality of care and patient satisfaction, nurses should be trained and supported to provide spiritual care. (shrink)

al-Tabarsī is one of the glossators in the Shī‘ah gloss tradition in the second middle period or first sagacity period. al-Tabarsī who had a wide knowledge in the various knowledge branches was mentioned as a glossator, narrator of Mohammad’s all sayings, deeds and approvals and scribe. One of compilations that al-Tabarsī wrote it in the field of gloss is Macmau-l-bayān fī tafsīri-l-Qur’ān. The glossator who widely included the recitations in this work used some evidence related to their averment while he (...) was reporting the recitations, and he made the recitations’ justification in the framework. The averment is a science which determines the correct recitations as distinguishing the correct one of recitation’s differences from the deficient one, and which founds an aspect of the correct category with all the other transferred and linguistic arguments of recitation in the predilection besides the imputation, the formal Qur’ān. Al-Tabarsī first mentioned the recitations under the subtitle of recitation related to the verses in each sura and then transferred the argument of recitations with the term of argument. So the glossator applied to give evidence on them with the linguistic and transferred arguments in each of the parts that the recitations were nearly mentioned. He mentioned the imputation, the Qur’ān lettering, verse, hadith, companion and natural people’s readings. He used Arabic poetry, Arabic idiom, dialect, grammar and syntax rules for the linguistic arguments. In this study, the evidences which were used in the recitations’ averment are reviewed in the sample of al-Tabarsī’s gloss in the name of Majmau-l-bayān. Summary: Full name of al-Tabarsī who was one of the leading scholar of Shī‘a is Fadl b. Hasan b Fadl al-Tabarsī. He was born in Thabaristan. According to some narration he was born in village named Tafrish which is between Kashan and Isfahan. He was called al-Tabarsī by reference to his hometown Thabaristan, according to another opinion he was called al-Tabarsī which comes from his birth place known as Tafrish located between Kashan and Isfahan. Tafrish was translated into Arabic as Tabars. Also, the commentator was known with nicknames such as Amīnü’l-islām, Amīnü’d-dīn and Umdatü’l-Mufassīrīn. He was called Sebzevarī due to the place where he died and named Maşhadī and Ṭūsī because of the place where he was buried. Although he is proficient in many fields, he has been described in the sources as commentator, muhaddīth and faqīh. Mufassīr has written many works in Islamic sciences. one of his works written in the field of commentary is Mujmau-l-bayān fī tafsīri-l-Qurʾān. Mufassīr stated that he wrote this commentary by taking advantage of Ṭūsī 's (d. 460/1067) al-Tibyān by saying “It is a guide from which I benefited from Tibiān light, and I write the subjects on the basis of his method”. The author started to write this work with the encouragement of some of his friends after he had aged quite a bit and his hair turned white. and he saw a gap in this area. He spent a lot of effort to fill that gap. This commentary, written during the first dirayet of the Shī‘a exegesis, is more moderate than the previous periods of Shī‘a commentators. The most basic indicator of this is the definitive rejection of the falsification of the Qurʾān in this period. The second important indicator is that insults and degrading expressions about the first three of the hulafā-i rashid and some of the companions are not accepted. The third important indicator is that most of the verses have been interpreted in a manner that corresponds to the views of the Ahl al-Sunnah school in linguistic analyses and proved by appealing to Arabic poems and sayings. al-Tabarsī mentioned recitation almost in all verses as a subtopic. He performed this in the surah by using subtopics. Then he has used “hujjatuhu” (its evidence) expression to narrate the evident of qirāʾāt. By doing so, commentator grounded qirāʾāts by using their evidences utilizing linguistic and narrative evidences in nearly every mentioned qirāʾāts. İhtijaj is a science that determines the authentic readings by distinguishing authentic readings from the weak ones, and that grounds the reading in the choice of an angle, which is mentioned in the authentic category, with isnād, Mushaf script and all other narrative and linguistic evidences. There are two types of ihtijaj which are ihtijaj bi-l-qirāʾāt ve ihtijaj li-l-qirāʾāt. İhtijaj li-l-qirāʾāt uses the linguistic evidences such as isnād, Mushaf line, Arabic language, consumables-nahiv pedestals, polish differences and the narrative evidences such as verses, hadith, qirāʾāt, Arabic words and poetry in determination and preference of a reading aspect. ihtijaj bi-l-qirāʾāt is the use of kıraa as evidence for any matter of science. al-Tabarsī has also mentioned detection proofs which reveal the authentic ways of qirāʾāt like isnād and rasm al-mushaf. Isnād is attribution to whom take the qirāʾāt from previous persons. This proportion reaches up to the Prophet. The persons in the chain of isnād constitute this chain. al-Tabarsī has given in preface the names of the recitors and narrators, which are famous in the cities, based on the fact that an authentic attribute is the basic element in the determination of the qirāʾāh. Thus he passed on the chains of isnād that reached up to the Prophet. Another thing that al-Tabarsī used in the determination proof of qirāʾāh is rasm al-mushaf. The commentator has used the spelling of al-mushaf scripture as evidence by saying “written in al-mushaf like this”. al-Tabarsī, also mentioned preferable evidences about ways of qirāʾā’s proof. Preferred proofs, are evidence to make choosing between qirāʾāh whose authenticity is defined by means of determination proofs. These evidences are divided into two parts which are determination proofs-based and special. Special evidence has not relation with the determination proofs. It contains evidence categories used to prefer one of the two authentic qirāʾāh as special. These categories are divided into four parts: linguistic, transplant, mental and private. al-Tabarsī has evidenced with verses of narrative proofs in the preferred evidence category. The commentator has mentioned about this method for qirāʾā evidence extensively. He has grounded qirāʾāh by using verses. al-Tabarsī also has evidenced these matters by using words of the Prophet from narrative proofs in the preferred evidence category. In this method commentator has evidenced from hadith after mentioning qirāʾāh ways. al-Tabarsī evidences from narrative proofs with qirāʾāh preferred evidence category. In this context, the commentator mentioned recitation of companion and followers by saying his qirāʾāh after reporting qirāʾāh. Moreover, the commentator has sometimes mentioned recitations which is related with reading seven of the recitation and reading ten of the recitation sciences qurra recitation and sometimes mentioned recitations which are known as shadhdh. Then, he has examined these recitations with the qirāʾāh of companions and followers. al-Tabarsī has benefited from narrative evidences, Arabic poetry and phrase in the preferred evidence category extensively. Another evidence used for examination of qirāʾāh is linguistic evidences. Qirāʾāh are related with Arabic language because it has connection with Qur’ānic wording which revelated in Arabic. al-Tabarsī has benefited from some things such as Arabic grammar rules and dialectic differences extensively. The commentator has benefited from Arabic grammar by emphasizing the meaning of the words with the literary features. He has explained grammar statement related with qirāʾāh aspects. He has also explained linguistic rules which are about aspects. (shrink)
