Can Online Sentiment Help Predict Dow Jones Industrial Average Returns?

In this paper, we explore the relationship between a Global Mood Time Series, provided by Wall Street Birds, and the Dow Jones Industrial Average (DJIA) from April 2011 to December 2011. My econometric results show that there is no long run equilibrium relationship between the level of global mood and the level of the DJIA. These results apply to the whole period, as well as in the six-month subperiods. Furthermore, daily changes in global mood do not Granger cause DJIA returns. However, changes in global mood do appear to be useful in forecasting the volatility of the DJIA, and my results suggest that GARCH models of volatility of large-cap indexes, and potentially the market as a whole, could be strengthened by including online sentiment measures of Big Data. Measuring global mood, and quantifying its impacts, can potentially lead to superior portfolio construction as forecasting volatility is an important input in portfolio optimization. The results, as a whole, suggest that Big Data can have important implications for investment decision-making

Effect of acupressure on cervical ripening

Background: Cervical ripening is one of the main stages of initiation labor. Acupressure in Chinese medicine is considered as an invasive technique, which through reliving oxytocin ripens the cervix. Acupoint Sanyinjiao (SP6) was selected in this study because it is the acupoint selected in gynecology and it is easy for women to locate and apply pressure without medical assistance. Objectives: The aim of this study was to determine the effect of acupressure on cervical ripening. Patients and Methods: In this randomized clinical trial, 150 primigravida with term pregnancy who had referred to Deziani hospital in Gorgan were chosen and divided to three groups: in the first group acupressure was done by the researcher while in the second groups this was performed by the mother her self, and the third group served as a control and only received routine care. For both intervention groups the pressure was applied on Sp6 for about 20 minutes during one to five days. Elements were checked from cervical ripening at 48 and 96 hours after intervention and at the time of hospitalization. The tools for gathering information included demographic characteristics and midwifery history questionnaire, daily records and follow up forms. Content validity was used for validity of tools. Reliability of the observation check-list and physical examination was confirmed by inter-rater scores (inter observer), and daily records by test-re-test. Data was analyzed by analysis of variance (ANOVA), Kruskal-Wallis and Chi-squared tests (P ≤ 0.05). Results: There was a significant difference between mothers’ educations in the three groups. Most of the mothers (59.5%) in the researcher-performed acupressure group had secondary education. Cervical ripening was significantly different between the three groups after 48 hours (P ≤ 0.05), yet there was no significant difference after 96 hours and at the time of admission. Mean Bishop score was enhanced after 48 hours in the researcher-performed acupressure group (P ≤ 0.021) and the self-performed acupressure group (P ≤ 0.007) in comparison to the control group. Conclusions: The results showed that acupressure is a safe technique and leads to cervical ripening. Thus, regarding the desired results that were achieved when mothers applied acupressure themselves, it could be suggested that it is beneficial for mothers to be trained to apply this method at home. © 2015, Iranian Red Crescent Medical Journal

The World Vision International Child Empowerment Program in Yahim Village: Implementation, Impacts and Challenges

Indonesia guarantees the right of every child to enjoy protection from the state, including protection from sexual and economic exploitation that threatens their lives. This study attempts to assess the implementation, the impacts, and the challenges of the WVI child empowerment program from the time it was first introduced in Yahim village in 2018 to the year 2021. A qualitative method is used in this study in conjunction with a descriptive approach to explain the topic. Primary sources, such as interviews, field notes, personal documents, and other official documents, as well as secondary sources, such as books, journals, and media articles, are also used in this study. This article shows that WVI implemented the programs successfully, despite facing some external challenges. The program has had some impacts, including a decrease in cases of violence against children, an increase in children's interest in literacy and gender equality, and children's activeness in expressing their voices about their rights. A key conclusion is that providing children with access to empowerment programs should be sustained as it will result in better long-term outcomes. Hence, WVI and other humanitarian organizations need to expand similar programs to other villages/ communities

Desain Interior Toko Buku Uranus dan Kafe Libreria dengan Konsep Eco Industrial

Membaca adalah salah satu kegiatan yang berguna untuk menambah wawasan. Wawasan sangat penting untuk meningkatkan pengetahuan sehingga masyarakat dapat meningkatkan kemampuan dan meningkatkan daya saing mereka. Hasil survey UNESCO pada tahun 2011 dikatakan bahwa minat baca masyarakat Indonesia hanya berkisar 0.001% yang berarti, dari 1000 masyarakat Indonesia hanya 1 orang yang memiliki minat baca. Sementara UNDP merilis angka melek huruf orang dewasa Indonesia hanya 65,5%, sedangkan Malaysia sudah mencapai 86,4 persen. Menurut perhitungan presentase UNESCO, Indonesia merupakan negara dengan tingkat minat membaca yang paling rendah di Asia. Toko buku Uranus Surabaya membuka sebuah kafe bernama Libreria Eatery sebagai salah satu usaha untuk meningkatkan pengunjung toko buku Uranus sendiri. Metode desain meliputi pengumpulan data lewat pengamatan lapangan dan penyebaran kuisioner kepada pengunjung dan remaja di surabaya. Metode pengumpulan data dilanjutkan dengan melakukan analisa sehingga didapatkan permasalahan dalam desain interior toko buku dan kafe tersebut dan dapat diberikan solusi solusi untuk pemecahan masalah interior yang ada serta dapat diterapkan pada elemen elemen pembangun ruang interiornya.

Konsep eco sendiri sebagai penyeimbang konsep industrial untuk memberikan kesan dinamis serta pemanfaat 3R yaitu Recycle, Reuse, Reduce dapat memberi nilai positif untuk bisnis tersebut

Strain self-sensing tailoring in functionalised carbon nanotubes/epoxy nanocomposites in response to electrical resistance change measurement

Carbon nanotubes (CNTs) are inherently multifunctional, conductive and possess piezo-resistive characteristics. Aiming at the multi-functionality of materials, nanocomposites made of epoxy resin with embedded CNTs are a promising solution for strain self-sensing applications. A critical parameter to achieve repeatable and reliable measure is the CNTs dispersion state in the resin. This study investigated the effect of CNTs concentration (0.01 wt% and 0.1 wt%), with different loading of surfactant Triton X-100, (0.0%, 0.2%, 0.5% and 1.0%) on strain sensing in terms of sensitivity and linearity based on electrical resistance data. The CNTs were synthesised directly using an injection floating catalyst chemical vapor deposition (ICCVD) process and their quality was characterised by Raman spectroscopy and scanning electron microscopy. Only the epoxy modfied with 0.1 wt% CNTs exhibited sufficient piezo-resistivity for the resistance measurements, and those with 0.01 wt% CNTs did not show sufficiently measurable conductivity so were excluded in our study, since their CNTs were highly entangled, and conductive network failed to be established. It was observed that, with 0.1 wt% CNTs, adding 0.5% content of the surfactant improved gauge factor. With more content of the surfactant (1.0 %), surprisingly, we observed a drop of gauge factor by the order of two. Therefore, by comparing the conductivity change between 1.0% and 0.5% surfactant, we postulated that the relatively high content surfactant has reached critical micelle concentration, and negatively affects CNTs dispersion state. The research presented in this article shows that moderate content of surfactant could improve piezoresistivity gauge factor while excessive surfactant could cause adverse effect
