In the last decade, Indonesia has worked towards expanding access to higher education, but the enrolment of the poor remains negligible with the majority of students in the country’s leading public universities still coming from Indonesia’s wealthiest echelons. Concerned with the issue of equity and access, the government has formulated a new policy calling on all higher education institutions to ensure at least 20% of their newly admitted students are of a low socioeconomic status (SES). The principal challenge the government has faced is a discrepancy between its ambitious political agenda and the policy’s implementation affected by inadequate budgeting, lacking implementation mechanisms, and limited award allocations. This challenge raises a question of whether the Equity and Access Policy can be effectively implemented and, if so, under what conditions can such success be achieved. We thus examine the country’s Equity and Access Policy, education system with its leadership structure, broader institutional framework, and how these factors interact to obstruct the higher education access for the poor in Indonesia. The inadequate policy implementation can impede Indonesia’s human capital development and the country’s economic growth.

The aim of this study is to examine the effect of temperature extraction on the potassium (K) and calcium (Ca) contents in orange and lemon peel extracts. The extractions were done at 62 ºC and 92 °C for 15 minutes and atmospheric pressure in distilled water. The fruit peel content in the extraction mixture was 5 % (w/v) in all samples. Calcium (Ca) and potassium (K) concentrations have been determined by flame photometric method. This research has revealed that by increasing the temperature of extraction, in particular, the concentration of Ca and K concentrations increased as applied extraction temperatures increased. The concentration of potassium is higher than the concentration of calcium in orange and lemon extracts, respectively. The concentration of K was 308 mg/l at 62 ºC and 361 mg/l at 92 ºC in lemon extracts, while in orange extracts the concentration of K was 476 mg/l at 62 ºC and 483 mg/l at 92 ºC. The concentration of Ca was 70.8 mg/l at 62 ºC and 71.9 mg/l at 92 ºC in lemon extracts, while in orange extracts the concentration of Ca was 91 mg/l at 62 ºC and 93.6 mg/l at 92 ºC. These results confirm that both citrus could be a very valuable source of potassium and calcium which are needed micronutrients to ensure the water and electrolyte balance and to build and maintain strong bones, proper function of muscles and nerves.

The paper analyzes through different historical periods in Indonesia the political instrumentalization of three prophetic narratives based on the prophecies of the medieval Javanese king Jayabaya, and looks at the ways in which millenniarist organizations and political activists have used the myths of the Savior and the Golden Age to achieve their own goals. The form of prophetic narratives has proved extremely productive in the process of channeling dissatisfaction and mobilizing for the purpose of political activism, and their interpretation does not only yield a clearer picture of the complex political situation and historical events, but also, through the actions of influential individuals, it provides insight into a number of other aspects of local culture, such as the forming of religious syncretism, the division of power in society or the cultural perception of time. The paper seeks to show that these prophecies do not aim to foretell future events, but rather serve as a means of ensuring the legitimacy of individuals in political struggles in the present time.

We examine the relation between real interest rate volatility and aggregate fluctuations for a diverse sample of countries. Compiling a new dataset including emerging and advanced countries, the substantial variation in our data yields novel results: (a) stochastic volatility outperforms Markov‐switching in representing interest rates, (b) some advanced economies can be more volatile than emerging markets, and (c) creditors take on more debt following volatility shocks. We show how an equilibrium business cycle model with uncertainty shocks can generate these facts. Sample heterogeneity produces significant parameter differences, playing an important role in distinguishing the effects of volatility shocks.

Large screen displays are omnipresent today as a part of infrastructure for presentations and entertainment. Also powerful smartphones with integrated camera(s) are ubiquitous. However, there are not many ways in which smartphones and screens can interact besides casting the video from a smartphone. In this paper, we present a novel idea that turns a smartphone into a direct virtual pointer on the screen using the phone's camera. The idea and its implementation are simple, robust, efficient and fun to use. Besides the mathematical concepts of the idea we accompany the paper with a small javascript project (this http URL) which demonstrates the possibility of the new interaction technique presented as a massive multiplayer game in the HTML5 framework.

Amyloid goiter is a very rare manifestation of amyloidosis. Here, we describe the case of a 40-year-old male, who presented with upper airway obstructive symptoms including hoarseness and breathing difficulty, to highlight the clinical and pathological features of secondary amyloidosis of the thyroid gland and the difficulties in making a preoperative diagnosis. The patient had previously been wounded in the war in Bosnia, which resulted in the right kidney being surgically removed. Further, he had undergone two surgical interventions on both hips due to osteomyelitis and was on a chronic dialysis program due to a progressively poor left kidney function that had eventually resulted in complete loss of renal function. Thyroid function tests were normal, and the patient clinically was euthyroid; biochemical investigations were within normal limits. Results from sonography, computed tomography scan of the neck, scintigraphy and fine-needle aspiration cytology were nondiagnostic. Therefore, a thyroid biopsy was carried out, and amyloid deposits were found. After preoperative work-up, total thyroidectomy was performed with no complications. We conclude that amyloid goiter may have no major impact on thyroid function even when a substantial amount of amyloid has replaced the normal thyroid parenchyma, as was the case in our patient. Amyloid goiter should be suspected in all patients with a progressive, rapidly growing bilateral thyroid enlargement with concomitant inflammatory processes or in patients undergoing hemodialysis treatment.

In view of the alarming situation related to coronavirus, of particular interest to the public, decision makers, health organizations, experts, professionals (epidemiologists, virologists, infectologists, psychologists, pulmonologists and others), it is also important to obtain seasonal weather outlook with general overview of the weather and climate conditions and how they would potentially affect the state of the COVID-19 transmission because a number of infectious diseases show seasonal features in their incidence. The analysis below represents an attempt to evaluate atmospheric processes that have a different spatiotemporal scale and depend on other modes of climate variability, and patterns of circulation and specific indices that affect seasonal variation and weather characteristics in a region. Based on seasonal outlook, the general impression is that sunny, warmer increase of (1.0 to 2.0°C) and frequently stormy weather conditions expected during May-June 2020 could likely give some optimistic scenario of slowing down the spreading of the virus further. This is confirmed with the further evaluation of the effective reproduction number, that is expected to decrease from 1.8 at middle of April to 1.2 at the end of June 2020. That is approximately 60-70 % reduction during this warmer period. However, the conclusions are still general and should be taken with caution as the situation is changing from day to day and many other factors including climate conditions, population density and medical care quality also play role in virus transmission.

In the fifth-generation (5G) mobile communication system, various service requirements of different communication environments are expected to be satisfied. As a new evolution network structure, heterogeneous network (HetNet) has been studied in recent years. Compared with homogeneous networks, HetNets can increase the opportunity in the spatial resource reuse and improve users’ quality of service by developing small cells into the coverage of macrocells. Since there is mutual interference among different users and the limited spectrum resource in HetNets, however, efficient resource allocation (RA) algorithms are vitally important to reduce the mutual interference and achieve spectrum sharing. In this article, we provide a comprehensive survey on RA in HetNets for 5G communications. Specifically, we first introduce the definition and different network scenarios of HetNets. Second, RA models are discussed. Then, we present a classification to analyze current RA algorithms for the existing works. Finally, some challenging issues and future research trends are discussed. Accordingly, we provide two potential structures for 6G communications to solve the RA problems of the next-generation HetNets, such as a learning-based RA structure and a control-based RA structure. The goal of this article is to provide important information on HetNets, which could be used to guide the development of more efficient techniques in this research area.

Non-orthogonal multiple access (NOMA) based wireless caching network (WCN) is considered as a promising technology for next-generation wireless communications since it can significantly improve the spectral efficiency. In this letter, we propose a quality of service (QoS)-oriented dynamic power allocation strategy for NOMA-WCN. In content placement phase, base station (BS) sends multiple files to helpers by allocating different powers according to the different QoS targets of files, for ensuring that all helpers can successfully decode the two most popular files. In content delivery phase, helpers serve two users at the same time by allocating the minimum power to far user according to the QoS requirement, and then all the remaining power is allocated to near user. Hence, our proposed method is able to increase the hit probability and drop the outage probability compared with conventional methods. Simulation results confirm that the proposed power allocation method can significantly improve the caching hit probability and reduce the user outage probability.

Background: The use of trolleys for transporting the patients and lifting and lowering them in the trolley is a repeated activity in the daily work of a nurse, and a very common cause of the load of the lumbosacral part of the spine and the consequent pathological deformity, and the onset of clinical symptomatology of painful lumbo-sacral syndrome. The high level of excessive biomechanical stress is associated with the established practice of using standard medical wheelchairs to move patients inside the hospital. The process itself depends on the characteristics of the patient, his or her weight, as well as his/her cooperativeness, but primarily depends on the nurse's mobility. Although nurses strive to be in a position that reduces the load on the lumbosacral part of the spine during practice, this is often impracticable due to the patient's inconsistency. Objective: To present the ergonomic analysis of the medical nurse's workplace while lifting the patient into the wheelchair and to display solution for improving working conditions and prevention of musculoskeletal disorders. Results:  By ergonomic module of this software, we got results that present load on lumbosacral region of spine of   medical nurses during their daily activities, especially in the position of lifting and lowering patients. It was concluded that maximal spinal loading decreases significantly and becomes less than critical (3,100 N) in the case of a wheelchair that has ability to automatically lift and lower patient. Conclusions:  The use of hospital wheelchairs with an mechanism for the automatic lifting and lowering of patients and with a sliding seat will reduce the load on the lumbosacral region of the spine, prevent the onset of lumbosacral pain syndrome, facilitates work for the medical nurse and allows nurse to handle the patient on her own. The prevention of lumbosacral pain syndrome improves the quality of work of the nurse and extends the working life. Use of this type of wheelchair is justified in terms of cost-benefit analysis.

This article reports on the development of tools to measure rights-based social work practices in Bosnia and Herzegovina. Previously validated scales - Human Rights Exposure in Social Work (1 scale), Human Rights Lens in Social Work (2 scales), and Human Rights Methods in Social Work (8 scales) - were translated and adapted for the Bosnian context. To complete the validation, social work students (N=296) were surveyed, and the resulting data were analyzed using exploratory and confirmatory factor analysis. The results yield 11 valid scales for measuring human rights constructs and promoting human rights goals in social work education, research, and practice in Bosnia and Herzegovina.
