The fast-increasing introduction of renewable energy sources (RESes) leads to some problems in electrical power network due to fluctuating generated power. A power system must be operated with provision of various reserve powers like governor free capacity, load frequency control and spinning reserve. Therefore, the generator’s schedule (unit commitment schedule) should include the consideration of the various power reserves. In addition, it is necessary to calculate the annual operational costs of electric power systems by solving the unit commitment per week of thermal power generators and pumped storages in order to compare and examine the variance of the operational costs and the operating ratio of the generators throughout the year. This study proposes a novel annual analysis for the thermal power generator and pumped storages under a massive introduction of RESes. A weekly unit commitment schedule (start/stop planning) for thermal power generator and pumped storages has been modeled and calculated for one year evaluation. To solve the generator start/stop planning problem, Tabu search and interior point methods are adopted to solve the operation planning for thermal power generators and the output decision for pumped storages, respectively. It is demonstrated that the proposed method can analyze a one-year evaluation within practical time. In addition, by assuming load frequency control (LFC) constraints to cope with photovoltaic (PV) output fluctuations, the impact of the intensity of LFC constraints on the operational cost of the thermal power generator has been elucidated. The increment of the operational cost of the power supply with increasing PV introduction amount has been shown in concrete terms.

The Independent Evaluation Group (IEG) assessed the effectiveness of Bank support for decentralization between fiscal 1990 and 2007 in 20 countries, seeking to inform the design and implementation of future support. Given the difficulties of measuring the results of decentralization, the evaluation used intermediate outcome indicators—such as strengthened legal and regulatory frameworks for intergovernmental relations, improved administrative capacity, and increased accountability of sub national governments and functionaries to higher levels of government and to citizens—to assess the results of Bank support in these 20 countries. To examine potential lessons at a sectoral level, the evaluation also assessed whether Bank support for decentralization improved intermediate outcomes for service delivery in the education sector in 6 of the 20 countries.

The links between plantation expansion and deforestation in Borneo are debated. We used satellite imagery to map annual loss of old‐growth forests, expansion of industrial plantations (oil palm and pulpwood), and their overlap in Borneo from 2001 to 2017. In 17 years, forest area declined by 14% (6.04 Mha), including 3.06 Mha of forest ultimately converted into industrial plantations. Plantations expanded by 170% (6.20 Mha: 88% oil palm; 12% pulpwood). Most forests converted to plantations were cleared and planted in the same year (92%; 2.83 Mha). Annual forest loss generally increased before peaking in 2016 (0.61 Mha) and declining sharply in 2017 (0.25 Mha). After peaks in 2009 and 2012, plantation expansion and associated forest conversion have been declining in Indonesia and Malaysia. Annual plantation expansion is positively correlated with annual forest loss in both countries. The correlation vanishes when we consider plantation expansion versus forests that are cleared but not converted to plantations. The price of crude palm oil is positively correlated with plantation expansion in the following year in Indonesian (not Malaysian) Borneo. Low palm oil prices, wet conditions, and improved fire prevention all likely contributed to reduced 2017 deforestation. Oversight of company conduct requires transparent concession ownership.

Occupational future time perspective (OFTP) refers to employees' perceptions of their future in the employment context. Based on lifespan and organizational psychology theories, we review research on OFTP and offer a meta-analysis of antecedents and outcomes of OFTP (K = 40 independent samples, N = 19,112 workers). Results show that OFTP is associated with individual characteristics and personal resources, including age (ρ = −0.55), job tenure (ρ = −0.23), organizational tenure (ρ = −0.25), educational level (ρ = 0.16), and self-rated physical health (ρ = 0.16), as well as job characteristics, such as job autonomy (ρ = 0.22). Moreover, OFTP is related to important work outcomes, including job satisfaction (ρ = 0.28), organizational commitment (ρ = 0.41), work engagement (ρ = 0.22), retirement intentions (ρ = −0.37), and work continuance intentions (ρ = 0.16). OFTP is also related to task (ρ = 0.11) and contextual performance (ρ = 0.20). Additional analyses show that OFTP predicts job attitudes and work performance above and beyond the effects of another developmental regulation construct, selection, optimization, and compensation strategies. Overall, the findings of our meta-analysis suggest that OFTP is an important construct in the context of an aging workforce.

Purposecurrent study intends to examine key human resources practices (human capital, training and rewards) that influence employee commitment and service recovery performance (SRP) of Takaful industry agents in Southeast Asian region. The Takaful industry is facing stiff competition with conventional insurance industry in Malaysia and Indonesia as the Southeast Asian region has a large Muslim population. SRP is crucial in insurance industry specifically in the Islamic Insurance (Takaful) industry and plays a vital and key role in sustainable competitive advantage for value addition for firms in future to acquire market.Design/methodology/approachThe data was collected from 350 front line agents of the Takaful industry operating in Malaysia and Indonesia on convenience sampling technique. Data was analyzed by using PLS-SEM to examine the relationship between constructs.FindingsThe results show that human capital, training and reward significantly influence commitment of employee which further influenced SRP to be improved. Mediation effect was also found to be influential and statistically positive and significant by employee commitment between key HR practices (human capital, training, rewards) and SRP.Originality/valuecurrent study contributed to the body of knowledge in explaining relationship of human capital to employee commitment and SRP, further, inconclusive findings between training and rewards was also explained in the Takaful industry of the Southeast Asian region.

Background Postmarketing commitments are clinical studies that pharmaceutical companies agree to conduct at the time of FDA approval, but which are not required by statute or regulation. As FDA increasingly adopts a lifecycle evaluation process, greater emphasis will be placed on postmarket evidence as a component of therapeutic evaluation. Therefore, the objectives of this study were to determine how often postmarketing commitments agreed upon by pharmaceutical companies at first FDA approval lead to new clinical trials and to establish the characteristics and rates of completion and dissemination of postmarketing commitments. Methods For new drugs and biologics approved in 2009–2012, we used public FDA documents, ClinicalTrials.gov, and Scopus, to determine postmarketing commitments and their characteristics known at the time of FDA approval; number subject to reporting requirements, for which FDA is required to make study status information available to the public (“506B studies”), and their statuses; and rates of registration and results reporting on ClinicalTrials.gov and publication in peer-reviewed journals for all clinical trials. Results Among 110 novel drugs and biologics approved by the FDA between 2009 and 2012, 61 (55.5%) had at least one postmarketing commitment at the time of first approval. Of 331 total postmarketing commitments, 33 (10.0%) were for new clinical trials; 27 of these were 506B studies subject to public reporting requirements, of which 12 (44.4%) did not have a recent (i.e., up-to-date) or closed (i.e., fulfilled or released) status provided publicly by the FDA. Although two postmarketing commitments were insufficiently described in FDA records to perform searches on ClinicalTrials.gov, nearly all (28, 90.3%) of the 31 remaining postmarketing commitments for new clinical trials were registered on ClinicalTrials.gov. Among the registered trials, 23 (23 of 28, 82.1%) were classified as completed or terminated, of which 22 (95.7%) had reported results. When considering all 29 completed or terminated clinical trials, registered or unregistered on ClinicalTrials.gov, only half (14, 48.3%) were published in peer-reviewed journals. Conclusions While only 15% of postmarketing commitments agreed to by pharmaceutical companies at the time of FDA approval were for new clinical trials, these trials were nearly always registered with reported results on ClinicalTrials.gov. However, only half were published, and despite FDA public reporting requirements, recent status information was often unavailable for 506B studies.

The main objective of this study was to establish the psychosocial profile of adolescents and adults who have admitted to committing child-to-parent violence (CPV) and were serving a judicial sanction or prison sentence, respectively. Two groups of participants took part in this study. The first group was made up of 89 male youths who were serving judicial sanctions, and the second group was made up of 70 men serving a prison sentence. A cross-sectional retrospective design with concurrent measurements was used in this study. Group differences in the exposure-to-violence variables were conducted. Automatic regression models were used to estimate a self-reported CPV. In relation to the variables of indirect exposure to violence, statistically significant differences between those who admitted having committed CPV and those who did not, irrespective of being adults or adolescents, were found for seeing violence in class and at home but not for seeing violence on the street or on television. Regarding the variables related to experiencing violence, the results showed statistically significant differences in experiencing violence at home but not in class or on the street. The best predictive model of CPV includes some of the dimensions of self-concept, specifically academic and family self-concept, as well as the avoidant and rational problem-solving styles and the negative orientation toward problems. The results have shown the existence of a CPV offender profile that is common to minors and adults.

PurposeAs universities are human capital intensive organizations, practices followed by a university for enhancing the satisfaction of its teachers can be of great help in attracting, retaining and managing highly qualified and competent teachers. The purpose of this paper is to empirically examine the impact of job satisfaction (JS) on organizational commitment (OC) of university teachers in India.Design/methodology/approachA total of 396 academicians are surveyed to assess the subjects’ responses to JS and commitment questionnaire. Structural equation modeling (SEM) was used in the process of statistical analysis.FindingsThe results confirmed a significant impact of JS on OC of university teachers in India. With 1 percent increase in estimates of pay and job security (PJS), organizational support (OS) and job challenge (JC), there would be 21, 36 and 49 percentage increase, respectively, in OC of university teachers. Of all the factors of JS, JC is the most significant contributing factor, followed by OC and PJS that help in motivating and retaining the teachers in higher education institutions in India.Research limitations/implicationsThe sample of the study has been chosen from the higher education sector in Northern India, and so it still needs to be explored whether the findings of this study can be replicated in different geographical areas and organizational settings for further verification and generalization.Practical implicationsEncouraging greater satisfaction among the faculty members may positively influence work-related behaviors, especially commitment among the teachers. The paper may benefit the decision makers in universities to follow the proactive practices to improve the satisfaction and commitment of teachers as educational performance is of priority on the national agenda.Originality/valueThe study provides useful insights about a JS-OC relationship model and informs the stakeholders on how to create an enabling environment at the policy and practice level that would help in attracting and retaining teachers in universities in India. It contributes to enriching the JS and OC literature in a sector and a country poorly addressed so far in research.

The use of compulsory community treatment (CCT) in Australia is some of the highest worldwide despite limited evidence of effectiveness. Even within Australia, use varies widely across jurisdictions despite general similarities in legislation and health services. However, there is much less information on whether variation occurs within the same jurisdiction. To measure variations in the use of CCT in a standardised way across the following four Australian jurisdictions: Queensland, South Australia, New South Wales (NSW) and Victoria. We also investigated associated sociodemographic variables. We used aggregated administrative data from the Australian Institute of Health and Welfare. There were data on 402 060 individuals who were in contact with specialist mental health services, of whom 51 351 (12.8%) were receiving CCT. Percentages varied from 8% in NSW to 17.6% in South Australia. There were also wide variations within jurisdictions. In NSW, prevalence ranged from 2% to 13%, in Victoria from 6% to 24%, in Queensland from 11% to 25% and in South Australia from 6% to 36%. People in contact with services who were male, single and aged between 25 and 44 years old were significantly more likely to be subject to CCT, as were people living in metropolitan areas or those born outside Oceania. There are marked variations in the use of CCT both within and between Australian jurisdictions. It is unclear how much of this variation is determined by clinical need and these findings may be of relevance to jurisdictions with similar clinician-initiated orders.
