AbstractDeciding how to jointly schedule jobs and perform preventive maintenance is a fundamental problem in flexible manufacturing systems, particularly those arising in semiconductor manufacturing. At the same time, past work in this area shows that, even when there is only one station and one type of job, identifying policies that minimize the amount of work‐in‐process (WIP) is a difficult problem. In this paper, we study a single‐station version of this problem with an arbitrary number of job classes, with the objective of minimizing average maintenance costs plus the weighted average amount of WIP. We identify conditions under which it suffices to schedule jobs according to both a server‐state‐dependent version of the cμ‐rule, and a static cμ‐rule where the average service rates are used. One of these conditions states that the ratio between the service rates should remain constant as the server deteriorates. When this assumption does not hold, scheduling with the cμ‐rule can in fact lead to an unstable system; we illustrate this using a simple example. On the other hand, we also present numerical evidence that cμ‐based scheduling performs well compared to other scheduling rules, and relative to a policy based on solving a Markov decision process.

AbstractInsurgency and other security challenges have intensified across Nigeria with a resultant displacement of over a million people from over 100,000 households who depend on interventions from government and non-governmental organizations for survival since 2009. We conducted the study to determine the level of involvement of the displaced persons in planning, implementation and review of these interventions, and the effect of the participation on satisfaction with the interventions among camp dwellers in selected camps in Borno, Nigeria. A total of 278 internally displaced persons (IDPs) across 9 IDP camps were surveyed using an interviewer-administered questionnaire. Data was collected using Android-based Open Data Kit (ODK), exported into Microsoft Excel, and analyzed with SPSS version 21. Out of the 278 respondents, 143 (51.4%) were male, 82 (29.5%) respondents were within the age bracket of 26-35 years and above (mean age 38.9±12.3), over 78% were married, and 29.9% were involved in trading before their displacement. Among the respondents, 256 (92.1%) had benefitted from at least one intervention during their stay in the IDP camps. Over 96% of the beneficiaries were female, compared to 87.4% of males, which was statistically significant (p<0.05). All the respondents within the age group 26-35 years and above 45 years old who had received information about the interventions were satisfied, and this finding was statistically significant (p<0.05). Overall, 91.5% of respondents who had benefitted from previous interventions would like to be involved in all the intervention stages (planning, implementation, and review). In comparison, 100% of IDPs who benefitted from previous interventions would like to be involved in the implementation, and 96.8% of them would like to be involved in planning the proposed interventions. To ensure maximum coverage, and that optimum benefit is derived from development projects, beneficiaries should be involved in all stages of the project cycle.

Abstract
Objective
Humanitarian-specific psychological distress following deployment can elude detection using contemporary measures of trauma-related stress. This study assesses the unidimensional structure and convergent validity of the Post-deployment Altruistic Identity Disruption Questionnaire (PostAID/Q), an 18-item questionnaire underpinned by the construct Altruistic Identity/Disruption (AI/AID).

Method
Humanitarian aid personnel (N=108) completed an online web survey, inclusive of the Moral Injury Questionnaire (MIQ), Posttraumatic Distress Disorder Checklist (PCL-5), Psychological Well-Being Posttraumatic Changes Questionnaire (PWB-PTCQ) and Social Provisions Scale (SPS).

Results
A confirmatory factor analysis suggested a single factor structure providing further support for the conception of AI/AID as a unidimensional construct. Convergent validity was demonstrated through (1) utility for predicting a posttraumatic stress disorder (PTSD) diagnosis assessed by the PCL-5, and (2) moral injury assessed by the MIQ. The PostAID/Q was further moderately and negatively associated with the availability of social support (assessed by the SPS) and lower self-reports of psychological well-being post trauma (assessed by the PWB-PCTQ). Finally, the PostAID/Q demonstrated evidence of incremental validity in predicting humanitarian specific psychological distress over and above the PCL-5. Specifically, the PostAID/Q predicted increased moral injury on the MIQ, and decreased psychological well-being post trauma.

Conclusions
The PostAID/Q can assist in identifying humanitarian specific psychological responses post deployment guiding support for personnel, over and above more traditional measures of posttraumatic stress.

AbstractThe professional nature and professionalisation of the street‐level delivery of activation policies have received increasing attention in academic debate. The study reported in this article contributes to this debate in two ways. The first way is to elaborate a multidimensional conceptualisation of practising professionalism in activation work, distinguishing eight dimensions: knowledge acquisition, knowledge sharing, knowledge use, innovation, accountability, client‐centred practice, collaboration and methodical work. The second way is to have developed and test a questionnaire for studying professional practice in activation work. Two models were compared in the study. The first model hypothesised that professional practice is a construct capturing all eight dimensions. The second model hypothesised that the eight dimensions reflect a knowledge‐oriented and a service‐oriented aspect of professional practice. The models were tested using data from a survey among Dutch activation workers. Both provided acceptable fits with our data. What model researchers consider most appropriate will depend on the focus of their research.Key Practitioner Message• This article helps practitioners in discussing and developing the professionalisation of the frontline delivery of activation policies.

Cultivation Right are rights to exploit land which is directly controlled by the state for agricultural, fishery or livestock companies for a period of time. One of the reasons for the removal of the cultivation right was because it was neglected. cultivation rights is one of the land rights that can be used as collateral for debt and encumbered with mortgage rights. The write-off of the mortgage rights because the write-off of land rights that are encumbered with a security right does not cause the guaranteed debt to be written off. In practice, the abolition of the cultivation right which is being subject to mortgage rights due to a decision to determine abandoned land creates confusion regarding the repayment of debts between the debtor (PT. Karatau Limo Sajati) and the creditor (PT. Bank Rakyat Indonesia Tbk.) And the difficulty of utilizing the former cultivation right object which is has been designated as abandoned land. The problems in this research are 1) how is the process of controlling cultivation right as an object of abandoned land in Solok Regency ? 2) what is the position of the mortgage rights above the cutivation rights which has been designated as abandoned land in Solok Regency ? 3) how is the utilization of the ex-cultivation rights land on which a mortgage has been imposed after it has been designated as abandoned land in Solok Regency ? The approach method used is juridical empirical, the nature of the research is descriptive analytical, the research data used is in the form of primary data, namely through interviews with sources and literature study to obtain secondary data. The data is processed systematically and analytically. The results showed that 1) the control process of PT. Karatau Limo Sajati as an abandoned land object which is carried out by means of inventory, identification and research, warnings, the proposal to determine abandoned land and the determination of abandoned land can actually be canceled through a lawsuit to the PTUN based on the weaknesses in the warning process. 2) the position of the mortgage over the cultivation rights which has been designated as abandoned land has been abolished, but the abolition of the mortgage because the termination of the land title does not cause the guaranteed debt to be canceled and subsequently the debtor's debt repayment is regulated in Articles 1131 and 1132 of the KUH Perdata. 3) The utilization of the ex-cultivation rights land on which a mortgage is imposed after it is designated as abandoned land is subject to a delay from BPN RI.

State defense is a concept closely related with National Defense System. Indonesian National Defense System bears following specific characteristics; universal, and involving all citizens, territories and other national resources. Meanwhile, corruption is the opposite of the nation's core values, which is against the national interest and the spirit of the nation, and does not stand in accordance with the noble values of Indonesia. Thus, corruption is a threat to the defense and security of our country. Corrupt behavior is a form of action against efforts to defend the state. The state defense program will emphasize the dissemination of the values of nationalism and love for the country. It is expected that the values instilled in the state defense program can prevent a culture of corruption from spreading to all members of society. Leadership is a series of leadership activities that cannot be separated from the position, style and behavior of the leader, as well as the interactions between the leader and their followers, in regards with the situation. UPN Veteran, which is a State Defense university, has met the aspects of consideration to become a PTN (public university) announced by the Ministry of Education and Culture. Of the three considerations of the conversion process from PTS to PTN, UPN Veteran has fulfilled two considerations, namely historical considerations and a special mission, by which UPN Veteran Jakarta has presented something novel that cannot be fulfilled by other public universities, namely as a State Defense university. The existence and progress of UPN Veteran Jakarta in the perspective of national character education is a necessity to be able to answer our various problems in society, nation and state.

The type of research used in this research is normative legal research. The position of the copy notary deed, which originally could be used as perfect evidence, becomes imperfect because the copy of the deed doesn't sound the same as the original deed, so that the copy of the deed doesn't meet the formal and material requirements of the deed making procedure. This can result in the copy of the deed being declared null and void. The legal implication of an agreement where a copy of the notary deed doesn't sound the same as the minimum deed, namely: the agreement can also be declared null and void as long as there is an agreement from the parties to cancel it because it results in losses for the parties and contains elements of error and fraud.

Social networks string everyone together. In the world affected by the COVID-19 pandemic, residents left their houses less often and maintained their connections online. Preparing for longer periods at home, some customers stockpiled supplies, the most discussed of which being toilet paper. When internet users came across videos of empty store shelves and people boasting about the amount of toilet paper they obtained, public contempt exploded over these supposed "panicked buyers." From February to May of 2020, patterns of reaction against panic buying matched the description of a moral panic as presented by sociologist Stanley Cohen. The media is an agent of contagions in a social network. During COVID-19, news headlines often detailed shortages of supplies around the world. Meanwhile, social media became a platform for videos of stockpiling consumers, like those who built thrones out of toilet paper boxes. These behaviors from the media further escalated a small issue of temporary toilet paper shortage to almost a national emergency, while drawing attention away from shortages of crucial medical supplies and test kits.

The Brazilian Constitution of 1988 represents a milestone due to the provision for comprehensive protection of children and adolescents. It was by this document with which the Police Department for the Protection of Children and Adolescents was created. This department is responsible for investigating sexual crimes. This research reflects the problems faced at the Police Department for the Protection of Children and Adolescents, in the city of Manaus, Amazonas state, Brazil. The study was based on bibliographic and documentary research, which prioritized the relevant legislation, records and institutional reports. It also employed direct observation at the police department and held interviews with 11 police sargeants and 3 psychologists, who were responsible for handling the complaints. The results reveal the high workload of these professionals in attending the public and solving the cases that come to their knowledge.

The paper focuses on how land property affects people's choices of migration from rural areas to urban areas. Based on the empirical analysis, the conclusion can be achieved that the migration is improved under market mechanism. Therefore, if the country wants to stimulate the human migration from rural areas to urban areas, the market mechanism should be built and people's land property should be protected.

Historical areas are one of the alternative tourism destinations in Semarang City. The most attractive and popular spot is the Semarang Old City, which is presently being prepared to become a World Heritage based on the beauty, authenticity and environmental attraction of the colonial buildings as well as the fascinating history of the area. However, most millennials prefer more recreational activities such as taking pictures, riding bicycles, sightseeing and enjoying the culinary surroundings without showing any interest in the history of the Old City. The potential importance of these millennials to the tourism market of this area requires the accommodation of their ever-changing needs. Therefore, researchers are encouraged to study young people's perspectives and preferences towards historical tourist destinations such as the Old City. This involved the application of the qualitative method to examine the characteristics, preferences and motivations of millennials travelling in historic tourism areas through observation and interview millennials. The findings of this study were expected to be used in setting up some strategies to overcome the inherent problems of historic site tourism and also to satisfy the needs of the tourists, especially the millennials.
