Published: September 2021

This study aims to predict the occurrence of erosion in the downstream Krueng Meureubo watershed, West Aceh Regency. Erosion is the loss of topsoil due to rain splash which is analyzed as a factor of rain erosivity, but the occurrence of erosion is not necessarily calculated by the occurrence of rain alone, but many other factors, such as soil erodibility, slope and length of land, land cover and the presence or absence of land conservation efforts. the. The Krueng Meurebo watershed shows a large sediment transport, with an indication that the river is getting shallower caused by sediment deposition at the riverbed, this sediment comes from sediment carried through the process of soil erosion. The method used in analyzing the occurrence of soil erosion in this study is the USLE method and uses a Geographic Information System (GIS). The results obtained are the distribution of erosion rate values in 228 polygons, with the largest erosion rate value occurring in polygon 1 with an erosion rate of 8495.308 tons/ha/year. The smallest erosion rate occurs in polygons 30, 34, 35, 179, and 180, with an erosion rate of 0 meaning that there is no land erosion event, which occurs in organosol and glehumus and regosol soil types, land cover is settlements and water bodies. It is concluded that the occurrence of erosion in a land is very dependent on the type of soil and the type of land cover. It is recommended for land with large erosion events to take serious land conservation actions so that erosion events can be minimized and do not occur continuously which of course can cause the watershed to become critical. Conservation efforts can be carried out in various ways, one of which is by vegetative means using plants that can reduce the rate of soil erosion.

The study aims to determine the price fluctuations and their effects on patchouli farm and patchouli oil production in Aceh Province. The Research Method used survey method with an explanatory research as an approach. The location of the study was conducted in Aceh Province, in Aceh Jaya Regency and Aceh Barat Regency. The fluctuations of patchouli oil price have an affect to the motivation of farmers in developing patchouli farming. Farmers in the study location tend to do patchouli farming when the price of patchouli oil is high, instead farmers do not do patchouli farming when the price of patchouli oil decreases. The fluctuations in patchouli oil prices determined by the quality of patchouli oil and market demand have a dominant influence on the development of production and the productivity of patchouli in Aceh. Standardization of patchouli oil quality at the agro-industry level will increase the price of patchouli oil at the farmers level and increase farmers' income. The price of patchouli oil fluctuates depends on Patchouli Alcohol (PA) levels. This is the main reason for traders at the district and provincial levels to reduce prices at the farm level. Aceh Patchouli has oil quality that qualified with basic export standards. But there is still a need for cultivation techniques and better application of refining technology to improve the quality of patchouli oil at the farmer level so that it can increase the price of patchouli oil at the farmer level while  simultaneously increasing the income and welfare of farmers. The phenomenon of patchouli oil price fluctuations in high has an important role in the development of patchouli oil agro-industry.

Galaxie Tennis: Un estudio de caso
Authors: Pestre Bernard
Published: September 2021

La enseñanza del tenis, como toda otra enseñanza, ha evolucionado considerablemente desde los años 70 cuando no era raro ver hasta veinte jugadores, niños o adultos, en la misma cancha, delante de un instructor, imitando los golpes de tenis, sin ni siquiera golpear una pelota o pelotear con un compañero. Gradualmente, con la idea de que la técnica no es más que un medio para un fin, el juego de tenis ha ganado terreno. Hoy, en la mayoría de las escuelas de tenis del mundo, podemos ver a los niños “jugando tenis” desde las primeras sesiones. Esto va de la mano con la evolución de la sociedad y con el estilo de enseñanza orientada a lo individual - ”democrático”, empático e interactivo (Reid, Crespo, 2009), que prevalece ahora en la enseñanza deportiva.

Authors: Krishna HS , PK Sreejisha , Dhote Chetan
Published: September 2021

Background and objectives: Shortening of hamstring has a negative impact on the posture of the pelvic region. The increase in stiffness of the hamstring may serve as a cause of low back pain and is also thought to predispose athletes to injury. The objective of this study was to compare the immediate effect of neural mobilization and myofascial release of suboccipital muscle on hamstring length in younger adults.
Methodology: This was a Comparative study conducted in a tertiary care hospital. A total 40 individuals between age group of 18-25 years having reduced hamstring length were included in this study. They were randomly divided into two groups by lottery method. Group 1 received neural mobilization and group 2 received myofascial release of suboccipital muscle. Ranges were recorded post treatment. Straight Leg Raise (SLR), Sit and Reach Test (SR) and Finger to Foot Test (FFT) were used to record pre treatment ranges
Results: The result revealed that hamstring length significantly improved in both the groups further between the groups comparison demonstrated that non-significant difference existed in improvement scores of SLR, where as statistically not significant but clinically significant difference was existed in improvement of FFT. Furthermore between groups comparison demonstrated that statically and clinically significant difference existed in improvement scores of sit and reach, indicating that neural mobilization was more effective in improving hamstring length then myofascial release of suboccipital muscle in improving hamstring length.
Conclusion: This study concluded that both neural mobilization and myofascial release of suboccipital muscle is effective in increasing length of hamstring muscle, where as neural mobilization was better when assessed with sit and reach test.

Sexual Behavior of Female Sex Workers in Makassar, Indonesia
Authors: Alwi M.Akbar , Hamzah Hadzmawaty , Mahfudah Ulfah
Published: September 2021

Introduction: Sexual workers have been considered a core group for HIV and Sexual Transmission Diseases (STDs). Their risk is higher than women in the general population. As a developing country, Indonesia is no exception, where sexual transmission has become the main driver for the development of the epidemic in recent years. The survey result of Makassar's AIDS Eradication Commission in 2014 showed that the number of FSWs in Makassar increased. The high number of FSWs in Makassar affect the number of HIV/AIDS cases apparently.
Method: This study used data from a rapid survey conducted by Makassar AIDS Eradication Commission in 2013. The survey was carried out to gain information about the sexual behaviour of FSWs in Makassar. The number of sample was 240 in which sampling was carried out using the C-Survey program system. A systematic questionnaire was used to gather data from FSWs, and data was analyzed by using STATA program.
Result: Most of the FSWs in this study are aged between 36-40 years old (27.9%). For the last sexual intercourse, most of the FSWs offered a condom to their clients (85.0%). However, the number of clients who used a condom for intercourse was lower that is 77.5%. The main reason why clients refuse to use a condom is that they are uncomfortable.
Conclusion: The awareness of FSWs to offer a condom is higher than the willingness of clients to use a condom consistently.

Published: September 2021

Objective: To describe the consequences of using artificial nipples to exclusive breastfeeding.

Materials and method: An integrative review carried out in the Medline®, Cinahl, Lilacs, Web of Science, and Scopus databases to answer the following question: What are the consequences of using artificial nipples to exclusive breastfeeding?

Results: 38 articles were analyzed; the analysis gave rise to two categories: neonatal factors and maternal factors influencing exclusive breastfeeding. Breastfeeding interruption was the neonatal factor most associated with the use of artificial nipples, while the level of maternal education stood out as an intervening factor in exclusive breastfeeding. Pacifiers were the dummy type more commonly mentioned, followed by feeding bottles and nipple shields.

Conclusions: The consequences of offering artificial nipples to breastfed infants are mostly negative and associated with the newborn, such as early weaning, refusal to breastfeed, impaired suction technique, incorrect latch-on, interference with orofacial development, and interruption of exclusive breastfeeding. Mothers who offered artificial nipples to their infants are more likely to experience pain, nipple fissures, frustration, and reduced interaction with their infants.

Semblances of Intimacy: Separating the Humane from the Human in Blade Runner 2049
Authors: Hiskes Andries
Published: September 2021

Denis Villeneuve’s film Blade Runner 2049 can be read as a postmodern detective story that explores the indeterminacy of whether its protagonist, K, is human or replicant. I argue that it is through the search for clarity between these two ontological categories that the film concurrently investigates how the aesthetic and ethical category of the humane becomes, or can become, separate and distinct from the ontological category of the human. Through this separation, I argue that the humane is characterized by the desire to establish and build connections of emotional and affective intimacy regardless of whether a subject is, or can be, ontologically characterized as human. Furthermore, through my reading of the film’s engagement with artificial memory, I argue that this allows us to reconsider the relationship between the notions of authenticity and intimacy, wherein the latter is not necessarily founded upon the former, but rather rests on the embodied capacity to feel and be affected. The construction of the humane in Blade Runner 2049 consequently develops as a posthumanist critique of a humanist cultural imagination in which the humane necessarily would be the exclusive domain of the human.

Studies on the calibration of subjective probabilities find that people tend to over-estimate the precision of their knowledge. In this paper we develop a semi-rational model and apply it to the real estate markets in Hong Kong and other Asian countries. The key point is that a person is rational about her/his private information until her/his private information is confirmed by a clearly defined market signal. Using a pre-sale as a mechanism of updating a developer's beliefs, this paper analyzes the impact of over-confidence on overbuilding and cycles in real estate markets. Our finding indicates that a pre-sale activity will increase the magnitude of over-building and over-confidence will increase the volatility in real estate markets. Our model also has implications to the well-established literature dealing with the issue of over-capacity in many industrial sectors.

A common puzzling phenomenon over the household survey of Taiwan is that the renters' saving rate is higher than that of the owners', while the latter has a higher average income than the former. One reason for this feature is that certain housing owners have to pay a greater amount of mortgage payment that is not included in saving. And on the other hand, the saving decision is correlated with the tenure decision, while the tenure decision is also correlated with the household's life cycle, in addition to income. And therefore, when one tries to estimate the correct saving rate, he or she has to consider the household's life cycle as well. In this study, we apply a data set of the household survey of Taiwan to investigate the correlation of life cycle, mortgage payment, and forced savings. First of all, we estimate the saving rate in a traditional way, and then estimate the saving rate after the adjustment of mortgage payment. To figure out the correct saving rate with the tenure decision, we evaluate different households' saving behaviors according to different cohorts, and consequently, we could check how life cycle plays its role in this model. And our finding is, that for every cohort, the forced savings is significant for owners with mortgage and for renters as well.

This paper examines the optimal operation strategies for income properties. Specifically, the rental rate and the operating expense should be set at levels to maximize the return on investment. The results suggest that for a given demand curve of a specific rental property, there exist optimal levels of the income ratio, the operating expense ratio, and the vacancy rate. With a Cobb-Douglas demand curve, we derived closed form solutions of these optimal ratios for a given income property. The relevant local comparative statics of these ratios also are derived. These comparative statics also provide insight into the optimal building size and optimal rehabilitation decisions. An empirical case study was conducted to demonstrate how the model can be applied in real life situations.

This study re-examines the relationship between real estate securities and inflation in a total of ten international markets. In addition to the raw data, both the orthogonalized and hedged approaches were adopted in order to strip out the general impact of the domestic equity market. The results revealed that there is minimal evidence of a positive relationship between real estate securities and inflation, which is in line with existing empirical evidence. However, the strong evidence of perverse relationship, noted in previous studies of REITs, is not robust throughout the other nine markets. The hedged and orthogonalized data also provided minimal evidence in favour of a positive relationship, both in the short and long terms.

The importance of housing investment in the national economy and its rapid growth have become distinct characteristics of the Chinese economy in recent years. However, at the same time, there is a concern that the economic growth heavily dependent on housing investment may compromise the stability and the health of the national economy. Using Granger causality analysis, this paper examines the interaction between housing investment and economic growth as well as that between non-housing investment and economic growth. We find evidence that housing investment has a stronger short run effect on economic growth than non-housing investment. We also find that housing investment has a long run effect on economic growth while economic growth has a log run effect on both housing and non-housing investment. Our findings suggest that housing investment is an important factor for the short-term fluctuations of economic growth, with its growth stimulating the economic growth and its slumps leading to downside fluctuations.

This paper examines cycles and common cycles in the property market and the economy. While focusing on common cycles, the study also incorporates common trends in the meantime, so it covers the whole spectrum of dynamic analysis. It has been found that property shares common cycles, particularly with those sectors that are the user markets of property. The mechanisms of common cycles and the relative magnitudes of cycles of the sectors related to property are discussed to shed light on property market behavior.

This study analyses the dynamic effects of specific macroeconomic variables (i.e. housing loan rates, inflation and employment) on the price of new houses sold in Greece. An error correction vector autoregressive (ECVAR) model is used to model the impact of the macroeconomic variables on real housing prices. Variance decompositions show that the housing loan rate is the variable with the highest explanatory power over the variation of real housing prices, followed by inflation and employment.

The Chinese government has embarked upon an effort to reduce the number of tenants living in publicly owned housing. This is a significant challenge for any government, but may be especially so for a country where private homeownership is a new option. Out of concern that many of its citizens could not afford to purchase their housing units, the Chinese government created the Housing Provident Fund. This program, which is similar to housing fund programs in other countries such as Thailand and Singapore, combines a 401(k)-like savings and retirement account with subsidized mortgage rates and price discounts to provide a mechanism through which an employee could save for, and eventually complete, a housing purchase.

A house is generally considered as a ‘roof over one’s head’, however, housing can be regarded as an investment or asset. Our paper focuses on this function of dwellings and develops a stochastic portfolio choice model for the housing market, which is easy to incorporate into medium and large-scale macro models. Theoretical results suggest that house prices move in line with households’ income, although house prices have a higher variance than income does. On the other hand the positive correlation between the return on housing investment and consumption not only implies positive relationship between the portfolio share of housing investment and excess return but also renders the housing wealth inappropriate in consumption smoothing. We use UK data to test these theoretical implications of the model. In this case, empirical results strengthen the model framework.

This research examines how well nominal income, nominal interest rates and employment explain temporal variation in nominal metropolitan area house prices. Rather than use a traditional model of real house prices, we explain nominal house prices with a measure of "intrinsic" house value that combines local economic factors with an affordable price based upon what the local median income household could afford to pay at prevailing interest rates. The affordable price variable captures local household income trends and current interest rates. We then relate temporal variation in observed house prices to "intrinsic" value and estimate the parameters of separate autoregressive house price models for 316 cities. We observe that the coastal markets exhibit much greater appreciation/ depreciation rates and much more volatility than cities in the central portions of the country. Here we focus primarily on the impact of interest rates on nominal prices in various MSAs, a factor that many housing analyst have pointed to when debating the existence of housing bubbles. Some markets are much more or less responsive to interest rates than others. Supply constraints may explain some of this increased responsiveness.

Although there have been many recent studies of the housing market and the possible housing bubble, very few studies take a micro-oriented approach. We construct a repeat-sales housing price index from a new data set for Irvine, California to understand recent trends in its housing market. Our analysis for 1984 to 2003 suggests that Irvine’s housing market did demonstrate traits of a bubble during certain periods of time. In fact, the bubble of the late 1980s and early 1990s appears to have been even more pronounced in Irvine. Our analysis does not, however, demonstrate conclusively that Irvine’s housing market has been experiencing a bubble the past few years.

As recommended in this paper, the UNEP FI is organizing a Property Working Group (PWG) to further examine the issues discussed here. Information about the PWG can be obtained from the authors. Responsible property investing (RPI) means maximizing the positive and minimizing the negative social and environmental effects of property investing, consistent with fiduciary responsibilities. Our understanding of these issues has progressed a good deal over the decades due to work by the United Nations and others. Property markets are inextricably linked to urban problems and better management of both new and existing properties is needed to resolve them. The perception that RPI necessarily dilutes investment returns should be challenged. There is mounting evidence that RPI can be financially sound and socially beneficial. Leaders have emerged that are demonstrating its feasibility. Their activity should be considered as a basis for best practice guidelines. There is a need to develop metrics for comparing progress on RPI. We recommend: 1) establishing an RPI working group, 2) summarizing prior reports on urban issues, 3) identifying investment strategies that are profitable and responsive to the issues, 4) clarifying the financial effects of different responses and improving our means of measuring them, 5) identifying best practices, 6) adopting a rating system, 7) supporting RPI investment funds, and 8) recognizing leaders in the field.

It is well known that expected returns vary by industry (Lyon et al., 1999), and that REIT-based mimicking portfolios may capture the information in real estate investment trust (REIT) prices (Downs, 2000). This study performs REIT-based mimicking portfolio analysis. The results indicate that when the Capital Asset Pricing Model and the Fama-French (1993) three- factor model are used to evaluate the performance of a REIT portfolio, the probability for making Type I error exceeds its significance level. Performance tests are better specified when mimicking portfolios are constructed with the firms from the REIT industry. In addition, the market beta of REIT portfolios appears to converge to the market beta of the NCREIF Index when REIT-based mimicking portfolios are included into the specification. The result is consistent with the notion that there is a strong linkage between REIT returns and the underlying real estate factor (Ziering et al., 1997).
Do Geometry Self-Efficacy and Spatial Anxiety Predict the Attitudes Towards Geometry?

Self-efficacy and spatial anxiety towards geometry are stated to be effective to improve teachers' attitudes towards geometry. Therefore, it is necessary to determine the effect of geometry self-efficacy and spatial anxiety on attitude towards geometry. This determines the extent to which the pre-service primary school teachers’ geometry self-efficacy and spatial anxiety predict their attitudes towards geometry. The study used the cross-sectional survey model and the sample was determined with the convenience sampling method. The sample consists of 165 pre-service primary school teachers attending a state university. To collect the data, the geometry self-efficacy scale, the spatial anxiety scale, and the geometry attitude scale were used. Multiple regression analysis was conducted in the data analysis to explain the predictors of the attitude towards geometry. It was found that the pre-service teachers’ geometry self-efficacy beliefs and spatial anxiety were high while their geometry attitude was medium. Their geometry self-efficacy positively and significantly correlated with the attitude towards geometry and negatively and significantly correlated with spatial anxiety. While the sub-dimensions of geometry self-efficacy; positive self-efficacy beliefs, use of geometry knowledge, and negative self-efficacy beliefs had positive effects on the attitude towards geometry, spatial anxiety had a negative effect on the attitude towards geometry.

Influence of social networks on the supporters communities in Bulgaria in the 2020/2021 season
Authors: Yordanova Hristina , Pondev Minko
Published: September 2021

The development of technology and the transformation of the Internet into a dominant channel of communication have led to intense and diverse changes in the behavior of moderate and extreme supporters of sports teams. The report presents a brief overview of the characteristics of the communities of supporters in Bulgaria: profile, structure and dynamics of formal and informal fan organizations throughout the country and abroad. The global pandemic and the closure of sports facilities have led to an intensification of the importance of cyberspace as a substitute for real events and phenomena. This report focuses on the features and dynamics of open and closed fan groups on social networks. For this purpose, 150 pages of organizations and groups of supporters of the most active communities in Bulgaria were studied through the method of content analysis. The report presents a brief overview of the socio-psychological characteristics of fan communities and makes a typology of groups and pages in the Bulgarian virtual space by deriving four main types with their basic characteristics: common pages, national groups, regional factions and leaders' pages. The analysis focuses on their mechanisms of influencing the attitudes and behavior of both extreme and moderate supporters, through identified behavioral patterns online and live in the relatively short period of attending sporting events.

Published: September 2021

O presente trabalho apresenta um breve olhar sobre o Programa Novos Caminhos, lançado pelo governo do presidente Jair Bolsonaro, em 8 de outubro de 2019, com o objetivo de fortalecer a política de Educação Profissional e Tecnológica, apoiando às instituições de ensino no planejamento da oferta de formação em consonância com as necessidades do setor produtivo e incorporando as inovações tecnológicas. A análise parte de levantamento documental e aponta implicações e desdobramentos dos três eixos: Gestão e Resultados; Articulação e Fortalecimento; Inovação e Empreendedorismo. O referencial teórico está alicerçado em: Antunes (2018), Mészaros (2008), Saviani (2007), Previtali e Fagiani (2015) e Freitas (2016). Os resultados preliminares sugerem que a iniciativa busca atender às demandas da nova ordem de acumulação capitalista, visto que os três eixos são focados no mercado e não no sujeito.
