The “Hypertension Approaches in the Elderly: a Lifestyle study” multicenter, randomized trial (HAEL Study): rationale and methodological protocol

Background: Hypertension is a clinical condition highly prevalent in the elderly, imposing great risks to cardiovascular diseases and loss of quality of life. Current guidelines emphasize the importance of nonpharmacological strategies as a first-line approach to lower blood pressure. Exercise is an efficient lifestyle tool that can benefit a myriad of health-related outcomes, including blood pressure control, in older adults. We herein report the protocol of the HAEL Study, which aims to evaluate the efficacy of a pragmatic combined exercise training compared with a health education program on ambulatory blood pressure and other health-related outcomes in older individuals. Methods: Randomized, single-blinded, multicenter, two-arm, parallel, superiority trial. A total of 184 subjects (92/center), ≥60 years of age, with no recent history of cardiovascular events, will be randomized on a 1:1 ratio to 12-week interventions consisting either of a combined exercise (aerobic and strength) training, three times per week, or an active-control group receiving health education intervention, once a week. Ambulatory (primary outcome) and office blood pressures, cardiorespiratory fitness and endothelial function, together with quality of life, functional fitness and autonomic control will be measured in before and after intervention. Discussion: Our conceptual hypothesis is that combined training intervention will reduce ambulatory blood pressure in comparison with health education group. Using a superiority framework, analysis plan prespecifies an intention-to-treat approach, per protocol criteria, subgroups analysis, and handling of missing data. The trial is recruiting since September 2017. Finally, this study was designed to adhere to data sharing practices. Trial registration: NCT03264443. Registered on 29 August, 2017

Personalisation in MOOCs: a critical literature review

The advent and rise of Massive Open Online Courses (MOOCs) have brought many issues to the area of educational technology. Researchers in the field have been addressing these issues such as pedagogical quality of MOOCs, high attrition rates, and sustainability of MOOCs. However, MOOCs personalisation has not been subject of the wide discussions around MOOCs. This paper presents a critical literature survey and analysis of the available literature on personalisation in MOOCs to identify the needs, the current states and efforts to personalise learning in MOOCs. The findings illustrate that there is a growing attention to personalisation to improve learners’ individual learning experiences in MOOCs. In order to implement personalised services, personalised learning path, personalised assessment and feedback, personalised forum thread and recommendation service for related learning materials or learning tasks are commonly applied

Enjoyed or bored?:A study into achievement emotions and the association with barriers to learning in MOOCs

MOOCs are accessible online personal development opportunities in which learners can expand their knowledge on many topics. Yet, the experience of barriers to learning often hinders learners from achieving their personal learning goals. Therefore, it is important to have insight into determinants that may influence the experience of (certain) barriers. This study investigated whether the emotional determinants enjoyment and boredom, which are known to impact learner achievement and motivation, affect the experience of (specific) barriers while learning in MOOCs. The results show that boredom did affect the experience of barriers related to technical and online related skills, social context and time, support and motivation, yet it did not affect the experience of barriers related to the design of the MOOC. Enjoyment was not correlated to any of the barriers. Furthermore, the same analysis comparing men to women again revealed that boredom did not significantly affect the experience of barriers related to the design of the MOOC, yet did significantly affect the experience of the other barriers. No, significant differences were found between males and females. These findings may serve as input for supporting learners in achieving their individual learning goals

Unlocking Indonesia’s Economic Potential Through OECD Accession

Aksesi ke OECD dapat membuka peluang bagi Indonesia untuk meningkatkan produk domestik bruto (PDB), memperkuat neraca perdagangan, serta menarik lebih banyak investasi. Hal-hal tersebut pada akhirnya akan mendorong pertumbuhan ekonomi yang berkelanjutan melalui penyelarasan tata kelola, kebijakan ekonomi, dan standar perdagangan Indonesia dengan praktik terbaik internasional. Penyelarasan ini juga akan meningkatkan kepercayaan investor, mendorong efisiensi pasar, serta mempererat hubungan dagang. Model computable general equilibrium (CGE) mengestimasikan bahwa aksesi ke OECD akan membawa dampak positif yang signifikan terhadap kinerja makroekonomi Indonesia. Jika bergabung dengan OECD, Indonesia diproyeksikan akan menerima arus masuk investasi sebesar US$ 87,7 miliar pada 2028, atau setara dengan 0,1% dari PDB Indonesia pada tahun tersebut. Porsi terbesar investasi ini (25%) diperkirakan berasal dari negara-negara anggota OECD. Dari segi indikator makroekonomi, tingkat investasi diproyeksikan lebih tinggi 1,2 poin persentase dibandingkan skenario baseline (tanpa aksesi OECD) dalam jangka pendek (2028–2030), dan 1,8 poin persentase dalam jangka menengah (2031–2035). Dalam jangka panjang, pertumbuhan investasi mengalami normalisasi setelah lonjakan investasi pada awal aksesi. Tingkat pertumbuhan PDB tahunan Indonesia diperkirakan lebih tinggi 0,8 poin persentase dibandingkan skenario baseline dalam jangka pendek (2028–2030), dan 0,9 poin persentase dalam jangka menengah (2031–2035). Dalam jangka panjang, pertumbuhan PDB mengalami normalisasi setelah lonjakan PDB pada awal aksesi. Penurunan surplus perdagangan Indonesia diperkirakan terjadi dalam jangka pendek dan menengah. Hal ini disebabkan oleh meningkatnya investasi yang mendorong permintaan impor hingga melampaui kapasitas produksi dalam negeri pada periode tersebut. Namun, dalam jangka panjang (2036–2045), neraca perdagangan diproyeksikan akan kembali menguat. Oleh karena itu, Pemerintah Indonesia diharapkan terus memberikan gestur terbuka dan adaptif sebagai kunci untuk mendukung proses penyesuaian ini.Accession to the OECD will pave the way for Indonesia to boost its gross domestic product (GDP), strengthen its trade balance and attract greater investment, thereby supporting sustained economic growth by aligning Indonesia’s governance, economic policies and trade standards with international best practices, enhancing investor confidence, improving market efficiency and strengthening trade relations. The computable general equilibrium (CGE) model estimates that OECD accession will bring notable benefits to Indonesia’s macroeconomic performance. If Indonesia joins the OECD, the country is projected to receive investment inflows totalling USD 87.7 billion in 2028, equivalent to 0.1% of Indonesia’s GDP in that year. The maximum share of this investment (25%) is expected to come from OECD countries. In terms of macroeconomic indicators, investment is projected to be 1.2 percentage points higher than the baseline (scenario without OECD accession) in the short term (2028–2030) and 1.8 percentage points higher in the medium term (2031–2035). However, in the long term (2036–2045), the investment growth rate is projected to be 0.38 percentage points lower than the baseline as the Indonesian economy stabilises after the initial boost from OECD accession. Indonesia’s GDP growth rate per year is expected to be 0.8 percentage points higher than the baseline scenario in the short run (2028–2030) and 0.9 percentage points higher in the medium run (2031–2035). However, in the long run, the annual GDP growth rate is expected to be 0.7 percentage points lower than the baseline, following the slowdown of investment growth. A narrowing of the Indonesian trade surplus is anticipated in the short and medium term, driven by increased investment that boosts import demand beyond current domestic production capacity. However, in the long term (2036–2045), the trade balance is projected to recover and strengthen. Maintaining an open and adaptive trade regime is crucial to supporting this adjustment
