Balancing earliness and tardiness within workload control order release: an assessment by simulation

Most Workload Control literature assumes that delivery performance is determined by tardiness related performance measures only. While this may be true for companies that directly deliver to end-customers, for make-to-stock companies or firms that are part of supply chains, producing early often means large inventories in the finished goods warehouse or penalties incurred by companies downstream in the supply chain. Some earlier Workload Control studies used a so-called time limit, which constrains the set of jobs that can be considered for order release, to reduce earliness. However, recent literature largely abandoned the time limit since it negatively impacts tardiness performance. This study revisits the time limit, assessing the use of different adaptive policies that restrict its use to periods of either low or high load. By using a simulation model of a pure job shop, the study shows that an adaptive policy allows to balance the contradictory objectives of delaying the release of orders to reduce earliness and to release orders early to respond to periods of high load as quick as possible. Meanwhile, only using a time limit in periods of high load was found to be the best policy.

The impact of students’ behaviour, their approach, emotions and problem difficulty level on the performance prediction, evaluation and overall learning process during online coding activities

Learning process while solving coding problems is quite complex to understand. It is extremely important to understand the skills which are required and gained during learning to code. As a first step to understand the students’ behaviour and approach during learning coding, two online coding assignments or competitions are conducted with a 1-hour time limit. A survey has been conducted at the end of each coding test and answers to different questions have been collected. In depth statistical analysis is done to understand the learning process while solving the coding problems. It involves lots of parameters including students’ behaviour, their approach and difficulty level of coding problems. The inclusion of mood and emotions related questions can improve overall prediction performance but difficulty level matters in the submission status prediction. Two coding assignments or competitions are analysed through in-depth research on 229 (first coding competition dataset) and 325 (second coding competition dataset) data points. The primary results are promising and these results give in depth insights about how learning to solve coding problems is affected by students’ behaviour, their approach, emotions and problem difficulty level.

Bahan hukum primer putusan hakim. Analisis data pada penelitian hukum yuridis normatif ini secara deskriptif kualitatif. Hasil penelitian diperoleh menunjukkan bahwa penjatuhan putusan pidana tambahan berupa pencabutan hak memilih dan dipilih dalam jabatan publik kepada terpidana korupsi merupakan upaya yang menjerakan bagi para terpidana korupsi serta upaya preventif terjadinya tindak pidana korupsi, akhirnya penulis merekomendasikan untuk agar hakim harus konsisten dalam menjatuhkan pidana tambahan pencabutan hak politik serta mencantumkan kapan mulai berlakunya serta batas waktu berlakunya. This study aims to analyze the defendants who were involved in a corruption case who have the right to be sentenced to additional crimes. This study is normative juridical research. Secondary data sources were primary legal materials for the judge's decision. Data analysis in this normative juridical legal research is descriptive qualitative. The results obtained show that the imposition of additional criminal decisions in the form of revocation of the right to vote and to be elected in public office to corruptors is an effort to deter corruptors as well as efforts to prevent corruption. Finally the author recommends that judges must be consistent in imposing additional crimes of political rights revocation and stating when it comes into effect and the time limit for this.

Peran Baitul Mal Langsa dalam Pengelolaan Zakat dan Infaq untuk Meningkatkan Pemberdayaan Masyarakat

This study aims to find out what the role of Baitul Mal in Langsa City is in Managing Zakat and Infaq to empower underprivileged communities identified as mustahik in Langsa City. various ways and means. The meaning of infaq is also something that is spent for good. Infaq also does not have a time limit as well as large and small. This type of research is Field Research or field research that is case study, namely research that is carried out intensively in detail and in depth on an organization, institution or particular phenomenon by collecting the necessary information by visiting homes or places of people or agencies who information will be asked. The approach used in this research is qualitative, namely research that needs to be carried out after the problem is researched qualitatively, but the solution has not been revealed. This research consists of primary data and secondary data. Primary data is obtained from survey results or results of in-depth interviews with the Head of Baitul Mal, Secretary and Staff or management who are the key to the ongoing activities of Zakat and Infaq Distribution. Meanwhile, secondary datasets were obtained by researchers from existing sources, such as an overview of the company, organizational structure, and so on. The results of the study show that Baitul Mal has a role to take care of, manage, collect, distribute, and utilize zakat. The collection of zakat is carried out by receiving or taking from the person who issued the zakat (muzakki) based on the notification of the muzakki.

Category of time limit in administrative procedural law

Administrative procedural law is full of numerous and varied procedural time limits which, as time-related categories, define the temporal boundaries of the administrative process and can act as an effective regulator of administrative procedural legal relations. The article examines the concept of time limit in administrative procedural law from the standpoint of integrativeness. It notes that the studied issue was not thoroughly elaborated in science, which appears to result from the young age of administrative procedural law as a separate branch. The research identifies substantial characteristics of the administrative procedural time limit. It reveals the temporal content of time limit in administrative procedural law. A conclusion is reached that the administrative procedural time limit results from the impact of temporal categories on the administrative procedural legal regulation when administrative cases are settled by a public administrative authority and a court. The administrative procedural time limit is recognised as a tool used for temporalizing the administrative process and aimed at ensuring the dynamism of administrative procedural activities through duration, speed, rhythm and cyclicity. The article identified the trend towards the legislative refinement of the administrative procedural time limits. In an integrative sense, the attributes inherent to the administrative procedural time limit reveal the versatility and rich inner content of the concept of time limit in administrative procedural law, which results from the legal synthesis of temporality and authoritative procedural activities of public administrative authorities and courts in settling administrative cases. The article proposed the definitions for the category of time limit in administrative procedural law both in a narrow and broad sense, as well as with an emphasis on the temporal side of the examined category.

Czas na podjęcie przez sąd decyzji w przedmiocie wniosku o zastosowanie tymczasowego aresztowania

This paper canvasses the problem of adequacy of time limit of 24 hours (as defined in art. 248 § 2 of the Code of Criminal Procedure and Art. 41 sec. 3 of the Constitution) for the court to assess the prosecutor’s request for pre-trial detention. Starting from the historical analysis of such a solution and then going through the characteristics of the scope of activities necessary to be taken by the court in such a short time and recalling selected procedural problems, visible mainly in the extensive penal economic cases, it was indicated that such a short deadline does not create general conditions for a reliable assessment of the legitimacy of the conclusion drawn. At the same time, the risk of transferring the effects of such inability to the suspect was indicated. Against this background, two main directions of possible normative changes are presented, including both the time limit itself and the accompanying solutions, allowing to create conditions for a more effective use of this inherently short period.

Pengaruh Faktor Sosial Dan Pribadi Terhadap Minat Beli Produk Peyek Aziz Tanpa Tanggal Kedaluwarsa Dalam Perspektif Ekonomi Syariah

Carrying out economic activities based on Islam is an order and has the value of worship. According to fiqh rules, every muammalah transaction is allowed as long as it does not conflict with the basic Islamic law, namely the Qur'an and hadith, including carrying out economic activities in the field of food processing business. The purpose of this study was to determine the influence of social factors and personal factors on consumer buying interest in Peyek Aziz products. The method used is descriptive quantitative with the number of samples used as many as 33 respondents in the Kertamukti sub-district, Campaka sub-district which was determined through probability sampling with random sampling technique. The results of this study indicate that personal factors affect consumer buying interest with a significance value of 0.000 < 0.05. Social factors are declared not to affect because the significance value obtained is 0.063 > 0.05. While social and personal factors jointly affect consumer buying interest with a significance value of 0.000 < 0.05. Based on these results, it is known that social and personal factors affect consumer buying interest in food without an expiration date of 0.515 or 51%. While the remaining 49% is influenced by other factors not examined. The sharia economic review regarding food without expired labels did not find any specific regulatory information. The inclusion of an expired label is an ijtihad in providing information on the appropriate time limit for consumption on food products with the aim of benefiting in maintaining property and life.

Analysis and Examination of the Sunni Commentators’ Views in Explaining the Temporal Extent of the Infallibility of the Prophets (PBUTH)

Sunni commentators have different views on the temporal extent of the infallibility of the prophets. While Some Ash'arites have expressed absolute infallibility, the Mu'tazilites believe that the Prophets (Peace Be Upon Them) have been infallible since the start of their prophethood. This study, by referring to Sunni interpretations, seeks analytical-critical processing of the method of Sunni commentators using the necessary tools and resources in expressing the time limit of the infallibility of the Prophets (PBUTH). Examination of the interpretators comments following verses about the infallibility of the prophets (PBUTH) shows that the opinon of the Sunni commentators on the fallibility of the Prophets before prophethood, lack using appropriate tools and is a claim without reason, and the cause of differences in views about the infallibility of the prophets after prophethood, is paying no attention to rational arguments and favoring religious beliefs by interpreting verses in order to prove one's opinion and imposing the mental background of the interpreter on the verses.

f(R) dual theories of quintessence: expansion-collapse duality

The accelerated expansion of the universe demands presence of an exotic matter, namely the dark energy. Though the cosmological constant fits this role very well, a scalar field minimally coupled to gravity, or quintessence, can also be considered as a viable alternative for the cosmological constant. We study f(R) gravity models which can lead to an effective description of dark energy implemented by quintessence fields in Einstein gravity, using the Einstein frame-Jordan frame duality. For a family of viable quintessence models, the reconstruction of the f(R) function in the Jordan frame consists of two parts. We first obtain a perturbative solution of f(R) in the Jordan frame, applicable near the present epoch. Second, we obtain an asymptotic solution for f(R), consistent with the late time limit of the Einstein frame if the quintessence field drives the universe. We show that for certain class of viable quintessence models, the Jordan frame universe grows to a maximum finite size, after which it begins to collapse back. Thus, there is a possibility that in the late time limit where the Einstein frame universe continues to expand, the Jordan frame universe collapses. The condition for this expansion-collapse duality is then generalized to time varying equations of state models, taking into account the presence of non-relativistic matter or any other component in the Einstein frame universe. This mapping between an expanding geometry and a collapsing geometry at the field equation level may have interesting potential implications on the growth of perturbations therein at late times.
