Construction of Low-Volume Roads Using Labor-Based Technology: Case Study of Mutare, Zimbabwe
Authors: Mukura T. E. , Shumba S. , Vassileva L. D. 
Published: January 2018

Abstract
There is a huge backlog in the construction and upgrading of roads in Zimbabwe and this situation is very much pronounced in residential areas due to the lack of readily available and relatively cheap road-building materials. In this paper, a project of the design and construction of low-volume roads in Dangamvura Extension, Mutare, is presented and thoroughly analyzed, with concentration on pavement structure and construction technology. Extensive geotechnical and soil investigations of the area, traffic counts and forecasting, as well as studies of suitable design parameters for pavement structure and requirements in applications of labor-based technology combined all aspects of engineering information needed for valuable conclusions and useful advice to residential estate development. Extensive laboratory studies and experiments were done to approximate the actual site conditions, thus including soil samples, California bearing ratio (CBR) at 1.5-m depth, traffic counts in a high-density area of similar coverage, and studies of natural water flows for the purpose of culverts and drains. In addition to the Zimbabwe Standards and Pavement Design Manual, a literature review and pavement structure examples of river sand seals were studied.

Published: January 2018

Salinity intrusion in coastal Bangladesh has serious population health implications, which are yet to be clearly understood. The study was undertaken through the ‘Assessing Health, Livelihoods, Ecosystem Services and Poverty Alleviation in Populous Deltas’ project in coastal Bangladesh. Drinking water salinity and blood pressure measurements were carried out during the household survey campaign. The study explored association among Socio-Ecological Systems (SESs), drinking water salinity and blood pressure.
High blood pressure (prehypertension and hypertension) was found significantly associated with drinking water salinity. People exposed to slightly saline (1000–2000 mg/l) and moderately saline (≥2000 mg/l) concentration drinking water had respectively 17% (p &lt; 0.1) and 42% (p &lt; 0.05) higher chance of being hypertensive than those who consumed fresh water (&lt;1000 mg/l). Women had 31% higher chance of being hypertensive than men. Also, respondents of 35 years and above were about 2.4 times more likely to be hypertensive compared to below 35 years age group. For the 35 years and above age group, both prehypertension and hypertension were found higher than national rural statistics (50.1%) for saline water categories (53.8% for slightly and 62.5% for moderate saline). For moderate salinity exposure, hypertension prevalence was found respectively 21%, 60% and 48% higher than national statistics (23.6%) in consecutive survey rounds among the respondents. Though there was small seasonal variation in drinking water salinity, however blood pressure showed an increasing trend and maximum during the dry season. Mean salinity and associated hypertension prevalence were found higher for deep aquifer (21.6%) compared to shallow aquifer (20.8%).
Localized increase in soil and groundwater salinity was predicted over the study area. Shallow aquifer salinity increase was projected based on modelled output of soil salinity. Rather than uniform increase, there were localized extreme values. Deep aquifer salinity was also predicted to exhibit increasing trend over the period. Study findings and recommendations are suggested for immediate and planned intervention.
Dispersion Profiles and Gene Associations of Repetitive DNAs in the Euchromatin of the Beetle Tribolium castaneum

Published: January 2018

Abstract
Satellite DNAs are tandemly repeated sequences clustered within heterochromatin. However, in some cases, such as the major TCAST1 satellite DNA from the beetle Tribolium castaneum, they are found partially dispersed within euchromatin. Such organization together with transcriptional activity enables TCAST1 to modulate the activity of neighboring genes. In order to explore if other T. castaneum repetitive families have features that could provide them with a possible gene-modulatory role, we compare here the structure, organization, dispersion profiles, and transcription activity of 10 distinct TCAST repetitive families including TCAST1. The genome organization of TCAST families exhibit either satellite-like or transposon-like characteristics. In addition to heterochromatin localization, bioinformatic searches of the assembled genome have revealed dispersion of all families within euchromatin, preferentially in the form of single repeats. Dispersed TCAST repeats are mutually correlated in distribution and are grouped in distinct regions of euchromatin. The repeats are associated with genes, are enriched in introns relative to intergenic regions, and very rarely overlap exons. In spite of the different mechanisms of repeat proliferation, such as transposition and homologous recombination, all TCAST families share a similar frequency of spreading as well as dispersion and gene association profiles. Additionally, TCAST families are transcribed and their transcription is significantly activated by heat stress. A possibility that such common features of TCAST families might be related to their potential gene-modulatory role is discussed.
Enfoque Espacial y Visiones Territoriales del Desarrollo Regional en el Ecuador (1952-1982). Estudios, programas y planes.
Authors: Nufrio Anna Vincenza 
Published: January 2018

Los cambios de escala de los procesos políticos-económicos impuestos por la globalización orientan cada vez más, en Europa, Asia y América Latina, las prácticas de la planificación territorial hacia la implementación de estrategias de desarrollo regional y sub-regional. La “regionalización” es un tema pendiente en la agenda política del Ecuador, y no obstante la actual Constitución establece que el país se organiza territorialmente en regiones, provincias, cantones y parroquias rurales, el desarrollo equitativo, la autonomía y la descentralización de los distintos niveles de gobierno siguen siendo objetivos a alcanzar. Este artículo respalda este debate indagando sobre el enfoque espacial y las visiones territoriales que entre 1952 y 1982 orientaron las propuestas de regionalización en el Ecuador. A tal propósito se analizan valiosos documentos inéditos (estudios, planes y proyectos) realizados por la JUNAPLA y el CREA: únicos ensayos de Planificación Regional realizados en el país, de manera particular en la Región Centro-Sur.
Construcción de hábitats sustentables en paisajes transformados de borde. Caso: Quiba-Arborizadora Alta, Bogotá-Colombia
Authors: Sanabria Buitrago Mayerling 
Published: January 2018

La investigación que da pie a este artículo se basa en el estudio de los modos de habitar en zonas de borde sometidas a notables transformaciones de paisaje. Esto con el fin de reconocer la viabilidad sistémica de un espacio de transición urbano-rural usando como herramienta metodológica un modelo relacional conceptual que permitaidentificar la complejidad de su situación. Con dicha implementación se pretende identificar de manera directa y ágil oportunidades alternas de intervención en este tipo de entornos que promuevan la construcción de hábitats de borde sustentable. En este proceso se describirá, entonces, un contexto particular de ocupación y uso del territorio en el sector Quiba-Arborizadora Alta, en la localidad de Ciudad Bolívar en Bogotá, Colombia; donde, con la ayuda de un modelo dinámico conceptual semi-cuantificado, se identificaron aquellas relaciones que se establecen de manera cotidiana en este sector de borde. Con dicho modelo se pudo señalar la posible tendencia de dicho paisaje complejo frente a cambios inducidos, lo que permitió distinguir aquellas acciones que fomentarían efectivamente cambios sustanciales hacia la sustentabilidad de las áreas de borde en grandes centros urbanos como la Ciudad de Bogotá.
El urbanismo contra lo urbano. La ciudad y la vida urbana en Henri Lefebvre
Authors: Delgado Ruiz Manuel 
Published: January 2018

Henri Lefebvre coloca en el eje de su teoría sobre la vida urbana la oposición entre el espacio vivido por quienes lo usan o sueñan y el espacio abstracto que creen organizar los tecnócratas de la ciudad, que raramente reconocen hasta qué punto su “creatividad” está sometida a intereses privados o institucionales. Tras ese espacio hipotético sobre el que urbanistas y arquitectos trabajan no hay otra cosa que mera ideología, es decir, fantasma que recubre y disfraza las relaciones sociales reales de producción. Frente -o de espaldas- a ese orden espacial meramente teórico de los “especialistas”, lo que las ciudades conocen es la actividad constante o inminente de lo urbano, entendido como apoteosis y exacerbación de lo social, dinamismo siempre activado de acontecimientos y quehaceres sobre el que los “expertos” aplican planes y proyectos, pero del que no saben en realidad nada, acaso por lo cual pugnan por anularlo.
The immediate and long-term effects of time perspective on Internet gaming disorder
Authors: Lukavská Kateřina 
Published: January 2018

Backgrounds and aims
This study focuses on the role of time perspective (TP) in Internet gaming disorder (IGD). An inventory-based study on 377 massive multiplayer online role playing game players was conducted, followed by a 3-year-follow-up in which 48 active players from the original sample participated. We proposed that TP factors (negative TP and future positive TP) will influence either the current presence of IGD symptoms or the further development of IGD over time. In other words, the effect of TP is stable. Finally, game usage patterns were analyzed in the sense of changes in playing time and IGD symptoms in gamers after 3 years.

Methods
To access the variables, two scales were administered through online inventory, the Zimbardo Time Perspective Inventory-short, and Charlton and Danforths’ Core Addiction Scale, both in 2012 (N = 377) and 2015 (N = 48). The amount of time that gamers usually spent playing were obtained through self-reports.

Results
The study’s primary presumptions were confirmed. Both negative TP and future positive TP were confirmed as significant predictors of the presence of IGD symptoms, either immediately or in the following 3 years. Data on game usage showed a significant decrease in playing time and IGD symptoms between year 0 and year 3 of the study.
Fertility-Sparing Treatment of Endometrial Cancer with Initial Infiltration of Myometrium by Resectoscopic Surgery: A Pilot Study

Published: January 2018

Abstract
Three women with a well-differentiated grade 1 endometrioid adenocarcinoma of the endometrium with minimal myometrial infiltration were treated with hysteroscopic resection and hormone therapy. The presence of myometrial infiltration has often been mentioned as an exclusion criterion for conservative management in young patients because of worsening cancer prognosis. The subsequent 5-year follow-up and the pregnancies achieved may confirm the choice of this temporary treatment and indicate a new option for fertility-sparing treatment in highly motivated patients.

Published: January 2018

Students of architecture have as a part of their training, the acquisition of Computer Aided Design proficiency in AutoCAD and Revit and other software, in order to be relevant in the global terrain. Currently, in the curriculum of the study of Architecture in Covenant University, the students are assembled in the Digital Design Studio with the advanced computer graphics suite on each system. As in the case of learning technologies, the use of new media is grounded in its value to support sound pedagogical approaches. This paper investigates the current study methods adopted in Architecture by administering questionnaires to undergraduate and postgraduate students of the 2016/2017 batch. The data collected showed a marked learning gap as a result of the adopted method of teaching. It is expected that the introduction of new media technologies and websites for hands-on training will lead to marked improvement in the knowledge dissemination and acquisition.

Authors: Nikhlani Andi , Sukarti Komsanah 
Published: January 2018

ABSTRACT The survival rate of blue swimming crabs and the larval metamorphosis processes are still low in hatcheries. The objective of this study was to evaluate the effects of different phytoecdysteroids doses on both the survival and the rate of Blue swimmer crab larvae metamorphosis. The study consisted of four different phytoecdysteroids treatments, namely: control (0 mg/100 g of feed), 1 mg/100 g of feed, 2 mg/100 g of feed, and 4 mg/100 g of feed. Each treatment was replicated three times. The survival rate of the larvae was analyzed through analysis of variance, while the rate of larval metamorphosis was descriptively analyzed. The results showed that the dose of phytoecdysteroid of 2 mg/100 g of artificial feed resulted in the highest survival and the fastest metamorphosis speed of crab larvae for zoea-2 and zoea-3, and the dose of 4 mg/100 g of artificial feed for stadia megalopa and crablet.

URBAN SPACES, RURAL SPACES, AND "OTHER SPACES" IN INDONESIAN FILM FLYERS (1966–1998)
Authors: Woodrich Christopher A. 
Published: January 2018

<p align="center">In this article, I examine some three hundred Indonesian film flyers released between 1966 and 1998. I identify three categories of spatial representation: urban spaces, rural spaces, and what I term "other spaces". Urban spaces utilize depictions of high-rises, landmarks, sexuality, crowds, and/or technology as markers of a (Westernized) modernity. Depictions of rural spaces, conversely, emphasize the beauty or dangers of the natural world, as well as strong emotions and primitivism. These depictions suggest the prioritization of an orderly urbanity over a disorderly rurality, with more orderly rural spaces only being locations for travel. "Other spaces", meanwhile, present and/or combine markers of urban and/or rural space, thus forcing viewers to differentiate between place and space and recognize both the constructed nature of space itself and the possible benefits of disorder.</p><p> </p>

<p align="center"> </p><p align="center"><strong>ABSTRAK</strong></p><p>Tradisi merupakan suatu bentuk kegiatan yang dilakukan terus menerus oleh masyarakat, sehingga menjadi suatu kebiasaan dan pada akhirnya menjadi bagian penting yang tidak bisa dipisahkan dari kehidupan masyarakat (Agus Riyanto, 2014:1). Tradisi membentuk suatu nilai-nilai budaya dan kearifan lokal yang menjadi pedoman bagi masyarakat dalam menjalani kehidupan sehari-hari serta menjadi suatu kekayaan budaya bagi suatu daerah yang harus dilestarikan dan dipertahankan keberadaannya. Sampai saat ini, masih banyak desa-desa di Jawa yang melakukan tradisi seperti itu. Desa tersebut adalah Desa Jaweng, Kecamatan Simo, Kabupaten Boyolali. Salah satu tradisi yang masih dilakukan adalah tradisi <em>selametan</em> kematian yang terdapat nilai-nilai Islam di dalam pelaksanaanya seperti adanya ceramah agama Islam atau tausiyah, membaca do’a-do’a, ayat-ayat Al-Qur’an, sholawat, dan berdzikir yang dikenal dengan <em>tahlilan</em>. Tradisi<em> selametan </em>setelah kematian tersebut sampai sekarang masih banyak dilakukan masyarakat di Desa Jaweng karena didorong oleh suatu sistem keyakinan dan kepercayaan yang kuat terhadap sistem nilai dan adat istiadat yang sudah berjalan turun temurun. Tulisan ini bertujuan agar masyarakat mengetahui bahwa keberadaan tradisi <em>selametan </em> kematian di Desa Jaweng tersimpan nilai positif dalam pelaksanaannya. Masyarakat di Desa Jaweng memiliki sudut pandang yang berbeda-beda dalam menilai tradisi tersebut. Seperti halnya ada masyarakat yang memiliki keinginan atau termotivasi untuk menghadiri dan mengikuti kegiatan tersebut dan ada juga yang menilai bahwa kegiatan semacam itu tidak perlu dilakukan karena tidak ada hadist yang mendasarinya. Tradisi semacam ini perlu diambil nilai positif yang terkandung oleh masyarakat itu sendiri. Seperti halnya tradisi tersebut untuk silaturrahmi atau sekedar menyambung ikatan saudara dengan masyarakat satu dengan yang lain yang menimbulkan rasa satu kepentingan dan kebersamaan sehingga muncul hubungan sosial yang erat.</p><p><strong>Kata Kunci: </strong><strong>I</strong><strong>slam, </strong><strong>J</strong><strong>awa, selametan, tradis</strong><strong>i</strong></p><p><strong> </strong></p><p> </p>
