Preservice Elementary Teachers’ Alternative Conceptions of Science
Authors: Koc Isil , Yager Robert E.
Published: November 2016

This study was conducted to investigate the extent to which preservice elementary teachers held alternative conceptions in fundemental elementary science concepts. Eighty-six preservice elementary teachers participated in this study. Twelve preservice elementary teachers participated in follow-up interviews. Data were collected through the use of Alternative Conceptions in Science Instrument (Schoon, & Boone, 1998), a participant information form, and utilization of interviews. The results indicated that the majority of preservice elementary teachers (67.4%) held a number of alternative conceptions with mostly in the physical science. Various sources of alternative conceptions emerged during the interviews. Findings from the study also confirmed that science courses completed do not seem to have influenced participants’ alternative conceptions. Overall, the results of the study suggest that more consideration be given to identifying and modifying of the alternative conceptions of science so that teachers could better help their own students arriving at more accurate conceptions.
Desarrollo de un programa piloto de gestión ambiental en microcuencas para mejorar la calidad de los ríos en la Reserva Forestal Golfo Dulce, Península de Osa, Costa Rica

Published: November 2016

Los procesos que lleven a un desarrollo sostenible deben incluir crecimiento económico, social y cultural. El uso del agua es el mejor indicador del grado de desarrollo social y económico de un país. Estudios sobre calidad de agua llegados a cabo en el pasado muestran la relación existente entre esta y su entorno socioambiental. 

En la Península de Osa (Costa Rica), el Sistema Nacional de Áreas de Conservación (SINAC) ha comprado terrenos dentro de la Reserva Forestal Golfo Dulce (RFGD) a particulares sin contar con políticas de compra, y desconociendo el impacto que su uso tiene sobre la calidad de las aguas.

El objetivo del proyecto fue elaborar un programa de gestión ambiental a través de la compra de terrenos, orientado a la protección o mejora de la calidad de las aguas. 

El uso de un modelo de predicción de la calidad del agua basado en variables socioambientales fue la herramienta que permitió evaluar el impacto de los cambios ambientales en la calidad del agua, a través del análisis de distintos escenarios en el área seleccionada para el estudio. 

Se encontró que los usos del suelo para pasto o charral-tacotal no ejercen una influencia negativa sobre la calidad del agua. Lo contrario ocurre cuando el suelo se usa con fines agrícolas. Se concluyó que el SINAC debe incrementar la compra de terrenos dentro de la RFGD cuyo uso idóneo sea como bosque, para contrarrestar el posible uso extensivo en actividades agrícolas en la zona costera del área de estudio donde el SINAC no tiene injerencia. 
Computer-Mediated Communication: A vehicle for learning
Authors: Grooms Linda D.
Published: November 2016

The axiom of humanity’s basic need to communicate provides the impetus to explore the nature and quality of computer-mediated communication as a vehicle for learning in higher education. This exploratory study examined the experiential communication perceptions of online doctoral students during the infancy of their program. Eighty-five students were electronically queried through a 32 item open-ended questionnaire within a 13 day time frame. Preliminary findings supported the experience of Seagren and Watwood (1996) at the Lincoln Campus of the University of Nebraska, that “more information widens learning opportunities, but without interaction, learning is not enhanced” (p. 514). The overarching implications stress that faculty development and instructional planning are essential for the effective delivery of online courses, and even more so when collaborative learning is used. Facilitating group communication and interaction are areas beckoning attention as we continue to effectively organize the online classroom of this new millennium.

An E-Learning Experience: A written analysis based on my experience in an e-Learning Pilot Project
Authors: Bose Kabita
Published: November 2016

This article reports the experience of an e-Learning pilot project selected by the Educational Technology Unit (EduTech) of the Centre for Academic Development (CAD), University of Botswana (UB). This e-Learning package was designed and delivered in connection with the three-credit course “Issues and Trends in Early Childhood Education” (EPI-642), which is required for the first year of the master’s program in the Department of Primary Education. The course was taught via a flexi-time, gradual, phase-by-phase transition from traditional face-to-face teaching to the electronic medium of an e-Learning lab (called SMART classroom). This course utilized a student centred e-Learning package that retained the learning qualities of traditional teaching, personal guidance, and mentoring, while seeking to enhance students’ research and computer skills.

Authors: Shachar Mickey , Neumann Yoram
Published: November 2016

This meta-analysis research estimated and compared the differences between the academic performance of students enrolled in distance education courses relative to those enrolled in traditional settings, as demonstrated by their final course grades/ scores within the 1990-2002 period.

Eighty-six experimental and quasi-experimental studies met the established inclusion criteria for the meta-analysis (including data from over 15,000 participating students), and provided effect sizes, clearly demonstrating that: (1) in two thirds of the cases, students taking courses by distance education outperformed their student counterparts enrolled in traditionally instructed courses; (2) the overall effect size d+ was calculated as 0.37 standard deviation units (0.33 < 95% confidence interval < 0.40); and (3) this effect size of 0.37 indicates the mean percentile standing of the DE group is at the 65th percentile of the traditional group (mean defined as the 50th percentile).

Educação e ideologia: uma análise ontológica
Authors: Rossi Rafael
Published: November 2016

Nos dias atuais, marcados predominantemente pela crise estrutural do capital, vários discursos e teses voltam a defender a necessidade de uma “neutralidade ideológica” frente aos processos educacionais em todas as instâncias. Partimos dos pressupostos mais gerais da relação que se estabelece entre a educação e a ideologia tendo por fundamento as bases históricas e ontológicas entre os complexos sociais com a totalidade e a categoria fundante do ser social: o trabalho. É por meio da abordagem ontometodológica que poderemos compreender corretamente a articulação entre estas categorias fundamentais para o debate teórico e ideopolítico em educação.
Mundo da vida e educação: racionalidade e normatividade
Authors: Mühl Eldon Henrique
Published: November 2016

Habermas passa a atribuir, a partir de 1990, um papel central ao mundo da vida que, como fonte da racionalidade comunicativa, é capaz de se opor ao processo de dominação sistêmica e manter a autonomia dos indivíduos. O texto explicita os argumentos que levam Habermas a considerar a espontaneidade do mundo da vida como fonte que assegura a validade cognitiva e normativa das ações dos indivíduos em interação e avalia o potencial crítico desse posicionamento na educação. A ideia orientadora é que o entendimento da vida escolar só pode ser atingido se levar em conta a forma de produção do mundo da vida dos atores que a compõem.
Ética e formação: o elogio ao processo argumentativo
Authors: Zuin Antônio , Costa Belarmino César Guimarães da
Published: November 2016

Em tempos de cultura digital, observa-se o acesso a uma quantidade incomensurável de informações sem que sejam feitas relações que poderiam transformá-las em conceitos. Uma vez que prevalece o uso instrumental de tais informações, arrefece concomitantemente a postura ética que o questiona. É nesse contexto que o professor ocupa um posto decisivo no que diz respeito à organização e à discussão de tais informações com seus alunos. Este artigo tem como objetivo argumentar que a postura de Pedro Goergen como educador oferta aos alunos um tipo de relação que faz com que a própria figura do professor seja eticamente ressignificada nessa sociedade de cultura digital.
Arendt y Benjamin: algo más que una amistad, algo distinto de unas coincidencias
Authors: Ramos Antonio Gomez
Published: November 2016

La relación intelectual oculta que sostenía la amistad entre Hannah Arendt y Walter Benjamin va más allá de la relación de amistad personal que sostuvieron en el exilio en Francia y más allá de las interpretaciones que la propia Arendt hace posteriormente de Benjamin, que lo colocan injustamente cerca de Heidegger. Este artículo se propone, más bien, buscar la conexión entre los dos en la lectura que hacen de Kafka como escritor de las parábolas de la vida moderna. En ellas, ambos encuentran la figura del paria y del refugiado expulsado de la sociedad administrada. Arendt encontrará también la posibilidad del paria consciente, dotado de la facultad de juicio que replica la figura benjaminiana de la redención.
Fontes de conflito na Pedagogia contemporânea
Authors: Flickinger Hans-Georg
Published: November 2016

O texto traz ao debate alguns aspectos elucidativos do fundo conceptual e estrutural do pensamento de Pedro Goergen relacionada ao campo triangular da ética, da política e da educação. O autor destaca os conflitos que subjazem à prática educativa e que causam tensões que dificultam o manejo dos desafios que se fazem presentes na educação atual, ponderando que tais conflitos somente perderão seu potencial perturbador se os profissionais da educação se conscientizarem da sua intromissão no espaço pedagógico. Para tanto, a Pedagogia precisa tornar-se um campo de problematização e enfrentamento das fontes desses conflitos.

A Bank Credit Model with Capital-Constrained Newsvendor Under Two Ordering Opportunities
Authors: Zhao Deli , Zhang Baofeng , Wang Zongshui
Published: November 2016

This paper proposes a financing system consisting of a bank under Mean-Variance criterion and a capital-constrained retailer, where the bank offers an unlimited credit to the retailer. The demand is assumed to be stochastic. The newsvendor is allowed to make an emergency order with a minimum reorder quantity threshold (RQT). It shows that under RQT, the newsvendor has different reorder strategies. The optimal primary order quantity and interest rate are derived, sequentially. Extension under perfectly competitive capital market is given. The mathematic model reveals that RQT and reorder price have significant effect on the optimal strategies.
Infill-Well Fracturing Optimization in Tightly Spaced Horizontal Wells
Authors: Safari Reza , Lewis Richard , Ma Xiaodan , Mutlu Uno , Ghassemi Ahmad
Published: November 2016

Cost-effective production from unconventional reservoirs relies on creating new reservoir surface area where fractures are extended into and produce from undepleted zones. Field observations indicate that infill-well fractures could propagate toward nearby producers and depleted zones. This communication between infill and producer wells has been seen to cause casing collapse, and negatively affect current production levels. In this paper, an integrated reservoir/geomechanics/fracture work flow is established to optimize infill-well treatment schedule and to minimize fracture communication between wells. In particular, the paper presents: (i) numerical evaluation of depletion-induced stress changes between tightly spaced producers, (ii) hydraulic-fracture curving in a perturbed stress field, and (iii) hydraulic-fracture communication between wells, and infill-well treatment-design optimization to maximize production.

A systematic study of depletion effects and the key parameters that control fracture curving allows us to improve the infill-well fracture design by minimizing the communication between wells while maximizing the hydraulic-fracture extent. Depletion perturbs the in-situ stress tensor in the formation around fractured horizontal wells. The analysis shows that the perturbed-stress field is a function of stress/formation anisotropy, fluid mobility, pore pressure, operating bottomhole pressure (BHP), and Biot's constant. A fracture-propagation model, coupled with the altered in-situ stress field, is used to predict the hydraulic-fracture propagation path(s) and their radius of curvature (i.e., if the stress state dictates that the fractures should curve). The analyses are performed for different infill-well treatment schedule(s), and yield the most-likely fracture geometries (taking into account uncertainties in a shale formation). Resulting infill-well fracture geometries are imported into a reservoir simulator to quantify the production and to identify the optimal design parameters.

The coupled work flow (reservoir/geomechanics/fracture) is then applied to a field example to demonstrate the feasibility of its application at the reservoir scale. The results show that (a) infill-well fractures between tightly spaced horizontal wells can intentionally be curved and (b) communication between wells and fracture-coverage area can be controlled by adjusting stimulation parameters to maximize recovery. Forward coupled modeling can be useful in guiding when to drill infill wells before the altered-stress state negatively affects production outcome.
Identification of the Most Sensitive Parameters of Winter Wheat on a Global Scale for Use in the EPIC Model
Authors: Zhang Xingming , Guo Hao , Wang Ran , Lin Degen , Gao Yuan , Lian Fang , Wang Jing’ai
Published: November 2016

Core Ideas

Using computer technology, crop models are widely used in agricultural research and applications.

Sensitivity analysis can screen sensitive parameters to calibrate the EPIC model for different regions.

WA, HI, and TBS had a greater influence on simulated wheat yield than other parameters.

Elevation had a higher impact on the sensitivity of crop parameters, especially on TBS (0.53) and HI (–0.47).

These results can increase the efficiency of regional calibration of the EPIC model on a large scale.

The purpose of this study was to identify the most sensitive parameters (MSPs) of the Environmental Policy Integrated Climate (EPIC) model for winter wheat (Triticum aestivum L.) simulations across the globe. First, 48 crop parameters related to the growth process of winter wheat were selected from the EPIC model. The range and distribution were assigned to each crop parameter. Second, a number of samples of parameter combinations (SPCs) were generated, containing 48 random values of model parameters for each grid. Winter wheat yields were simulated to correspond with the SPCs. Then the SPCs and 10‐yr average yields were used in a sensitivity analysis that utilized the Extended Fourier Amplitude Sensitivity Test approach. The results showed that harvest index (HI), biomass/energy ratio (WA), and base temperature for plant growth (TBS) were the common MSPs worldwide, and they affected 73, 71, and 70% of the grids, respectively. Sensitive parameters vary among different regions and may be affected by environmental factors. Elevation influences the winter wheat sensitive parameters greatly. The results can serve as a reference for calibrating the EPIC model in different regions to increase the calibration’s efficiency on a large scale. The sensitivity analysis of crop parameters in different regions at a global scale is especially conducive to model calibration in regions lacking experimental data or a priori knowledge and can improve the accuracy of the model when adjusting different parameters in different regions.
Under‐ or Over‐Application of Nitrogen Impact Corn Yield, Quality, Soil, and Environment
Authors: Sadeghpour Amir , Ketterings Quirine M. , Godwin Gregory S. , Czymmek Karl J.
Published: November 2016

Core Ideas

Nitrogen application mid‐season cannot overcome drought stress later in the season.

Except for crude protein, under‐application of N did not impact forage quality.

Soil organic matter decreases in a chisel‐disked corn silage system regardless of N fertilizer rate.

Use of compost, cover crops, and conservation tillage can offset soil organic matter losses.

Under‐applying N by 30 kg N ha−1 was economically more detrimental than over‐applying.

Under‐ or over‐application of N fertilizer to corn (Zea mays L.) has adverse economic and environmental consequences. A 5‐yr study was conducted to determine the impact of N fertilizer on corn silage yield, quality, soil properties, farm economics, and nitrogen‐use efficiency (NUE). Corn silage yields were 12.9, 14.2, and 14.7 Mg ha−1 with most economic rate of nitrogen (MERN) of 90, 95, and 114 kg N ha−1 in 2001, 2003, and 2004 (the three responsive years), respectively. In 2002 and 2005 (non‐responsive years), yields averaged 9.1 Mg ha−1. Yield increased by 3.3 Mg ha−1 with each 10 cm of precipitation in July and August. At the MERN, NUE ranged from 16 (2001) to 25.8 kg DM kg N−1 (2004), reflected in greater soil NO3–N (0–20‐cm depth) at harvest in 2001 as well (23 vs. 8.9 mg kg−1 in 2004). Soil NO3–N at silage harvest in responsive years ranged from 8.9 (2004) to 23 mg kg−1 (2001) in 2001 and in non‐responsive years averaged 22 mg kg−1. Soil NO3–N at harvest was not a good indicator of crop N responsiveness or NUE. Nitrogen addition beyond the MERN decreased NUE and soil pH, and increased crude protein (CP). Under‐application decreased CP and yield in N‐responsive years and increased NUE. Soil organic matter (SOM) was decreased regardless of N rate. Overall, application of 30 kg N ha−1 below the MERN was economically more detrimental than fertilizing the same amount above the MERN.
Switchgrass Biomass Quality as Affected by Nitrogen Rate, Harvest Time, and Storage

Published: November 2016

Core Ideas

Switchgrass, being an efficient perennial biofuel crop, can be used as an alternative to fossil fuels and help in the sustainability of energy. Thus, it is important that we understand the effect of storing switchgrass for extended periods of time.

Storing switchgrass for an extended period may have an impact on quality and yield.

Storing switchgrass in bales or as a standing crop in the field are two storage methods assessed in this study.

The purpose of this study was to assess the changes in switchgrass (Panicum virgatum L.) biomass quality as affected by N rate, harvest time, and storage. This research was conducted near Bristol, SD, in 2010 and 2011. Treatments included three N rates (0, 56, and 112 kg N ha−1) applied annually and each N rate replicated four times. After a killing frost, all of the plots were harvested and baled in large round bales in October 2010 and November 2011. An area of about 30 m2 from each plot was left unharvested to represent storage of standing switchgrass over the winter and to determine dry matter yields. Switchgrass was analyzed for hemicellulose, cellulose, lignin, mineral elements, N, and C. In the first season, storage of the fall harvested switchgrass bales numerically increased the concentrations of hemicellulose, lignin, and N. In the second season, they increased significantly. Mineral elements significantly increased in both sampling seasons. Delaying harvest until spring decreased lignin, N, and mineral elements concentration, and increased cellulose and hemicellulose concentrations, but also reduced biomass yield. Results from this study suggest that delaying the switchgrass harvest until spring increased the overall feedstock quality for ethanol production, but yield reductions must be considered to determine the overall economic impact of a delayed harvest.

Published: November 2016

A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the multi-temporal variations of ET considering the combined impact of environmental factors (air temperature (AT), relative humidity (RH)) and groundwater in homogeneous and layered soils were focused on. During the whole growing period, the ET peaked at 14:00–15:00 on a daily basis. The variation in daily ET followed a bell curve during the entire growing period. The 5-day ET reached its maximum during the 12th leaf and maturity stage. The correlation coefficient between ET and AT reached its maximum value of 0.70 during planting and the third leaf stage. The negative correlation coefficient between RH and ET reached its maximum during the 12th leaf and tasseling-silking stage. Groundwater recharge was positively correlated to ET and the daily contribution was up to 10.07%. The silt sandy loam–loam layered soil was favorable for water and nutrient uptake during the entire growing period of maize.
Limiting swimming pool outbreaks of cryptosporidiosis – the roles of regulations, staff, patrons and research
Authors: Ryan Una , Lawler Sheleigh , Reid Simon
Published: November 2016

Cryptosporidium is the leading cause of swimming pool outbreaks of gastroenteritis. Transmission occurs through the ingestion of oocysts that are passed in the faeces of an infected person or animal when an accidental faecal release event occurs. Cryptosporidium parasites present specific challenges for infection control as oocysts are highly resistant to chlorine levels used for pool disinfection, infected individuals can shed large numbers of oocysts, there is a long incubation period and shedding of oocysts occurs even after symptom resolution. The purposes of this review are to identify key barriers to limiting swimming pool-associated outbreaks of cryptosporidiosis and to outline needs for research and collaboration to advance co-ordinated management practices. We reviewed swimming pool-associated cryptosporidiosis outbreaks, disinfection teachniques, current regulations and the role of staff and patrons. Key barriers to limiting swimming pool-associated outbreaks of cryptosporidiosis are a lack of uniform national and international standards, poor adherence and understanding of regulations governing staff and patron behaviour, and low levels of public knowledge and awareness.

Objective:

This work aimed to investigate some psychosocial factors related to burnout. Specifically, we explored the sample characteristics for moderate/high emotional exhaustion, cynicism and professional inefficacy, as well as the relationship between both working and environmental variables and burnout.

Method:

A cross-sectional study involving 307 nurses from one Italian hospital was carried out. A self-reported questionnaire was used to collect data. Data analysis was performed by using SPSS 19.0.

Results:

The results showed that there was a significant difference between nurses with low and moderate/high burnout in all the three components in almost all the examined organizational variables. In addition, we found that the aspects of working life had a significant impact on the three dimensions of burnout.

Conclusions:

The findings of this study not only can provide useful basis for future research in the field, but also can offer practical suggestions for improving nursing practice and promote effective workplace, thus reducing the risk burnout among nurses.
Micellar Enzymology- Chemistry and Applications

Published: November 2016

Enzymes in aqueous environment usually deal with purified enzyme preparations isolated from living matter which does not mimic real catalytic properties in vivo. Interaction of enzymes in nature takes place with different surfaces composed from lipid membranes or they get incorporated into biomembranes. Although Water is not a dominating component in the cytoplasm but plays a structural role by participating in the formation of biocatalytic complexes like glycoproteins. Water is needed to keep biocatalyst in active confirmation and hence plays very crucial role in biocatalytic reactions, activity and stability so that it can be used for various applications. This review focuses on composition, preparation properties and parameters which influence enzymes in reverse micelles and application of micellar enzymology to study protein chemistry, shifting equilibrium of various reactions, to recover various products by partition chromatography and bioremediation of chlorophenolic environmental pollutants.
UNDERSTANDING LAND IDLING AS A STRATEGIC BEHAVIOUR: A BRIEF NOTE USING THE REAL OPTIONS APPROACH
Authors: Khalid Haniza
Published: November 2016

One possible explanation for land idling in a rapidly transforming economy can be found by looking at the value of the option to wait and hysteresis behaviour in the land market. If investors assume that the drop is temporary and that its long term prospects outweigh current holding losses, the market will observe some form of a zone of inactivity i.e., no selling and no additional buying. The fact that landowners elect to keep their valuable land underdeveloped for prolonged periods of time suggests that idled land is more flexible and valuable than what the current market price suggests. If the revenue from farming is insufficient to sustain the activity, land is left idle; although this operational decision is open to continuous revision. The numerical example shown in the paper shows that price of land can be substantially bolstered by the option to wait embedded in land. We argue that land market prices are based on more than the land’s total present value of its future income stream. In a transforming economy, the option to wait and change land-use are especially important to consider. Policy-wise, the government can discourage land idling by ensuring appropriate and suitable zoning of agricultural areas, strong adherence to the zoning conditions/plans as well as more far-sighted land conversion decisions. These efforts can go a long way to reduce the source and degree of uncertainty which is the most important cause of real option premium in land prices. Based on the nature and type of data available, future directions of research should emphasize on empirical testing of real options premium in sale prices of agricultural land.
A STUDY ON THE EFFECTS OF ROAD HUMPS IN REDUCING SPEED ALONG LOCAL ROADS IN RESIDENTIAL AREAS: CASE STUDY OF TAMAN SETIAWANGSA
Authors: Ahmad Sofi Siti Syawani , Kadar Hamsa Abdul Azeez
Published: November 2016

The increasing number of vehicles along local roads in many residential areas has created unconducive environment and safety risk due to the increase in the speed passing vehicles. To control the speed of the vehicles, road humps were installed along local roads. This paper evaluates the effects of road humps on the speed of vehicles in Taman Setiawangsa, which is one of the residential areas in Kuala Lumpur. The field observational survey was carried out to collect data on design characteristics of the road humps. A spot speed survey was administered to collect spot speed of vehicles at different points near the road humps and the spot speed data at and near road humps were analysed using measures such as descriptive statistics and dependent t-Test. The design characteristics of the road humps were also compared with the existing road hump guidelines published by the authorities. The major finding of this study depicts the effectiveness of road humps in reducing speed in relation to the road hump’s profiles.

Published: November 2016

In the past few decades, cities from various parts of the world have faced with unplanned and uncontrolled physical expansion due to inappropriate policies. Among different solutions against urban sprawl, the dominant sustainable cure is the so-called 'Urban Consolidation' (UC). This paper aims to explore urban sprawl characteristics and present its cause and effect on the sustainability criteria of Shiraz city, Iran. It is confined to an exploration of population growth and physical expansion of the city. The data has been collected from governmental organizations and documents. This paper examines UC policy implementation in the inner city of Shiraz to control low-density urban sprawl. As the result, this paper discovers that the policy emphasizes on the higher density housing development in existing urban areas considering the capacity of infrastructures and facilities’ availability prior to calculate housing targets to decrease the demand for Greenfield development. It concludes with a brief discussion on the challenges to achieve sustainable urban development goals in the city through UC strategies.
DEMOGRAPHIC TRANSITION AND SUSTAINABLE COMMUNITIES IN MALAYSIA
Authors: Elsawahli Hanan , Ahmad Faizah , Ali Azlan Shah
Published: November 2016

As a developing country, Malaysia is undergoing a demographic transition from a high fertility and mortality rural society towards an industrialised society with low fertility and mortality rates. This transition involved an increased growth rate of elderly population. The number of elderly has risen from 1.4 million in 2000 to 2.1 million in 2010 and is projected to be 3.4 million by 2020. A population aging needs to accumulate assets in order to achieve sustainable development goals. This represents the main challenge to planners and policy makers in terms of designing aged-friendly neighbourhoods to meet the elderly needs. This paper aims to review the population aging trends and policy framework available for the elderly in Malaysia. The paper further discusses the sustainable neighbourhoods related to active aging. The paper concludes by identifying fundamental gaps in both knowledge and policy associated with planning for the aging population and successful aging.

In line with the principle of sustainable development, construction projects ought to be developed to bring benefits across all aspects, namely economic, social, and environmental. One the other hand, being a complex, fragmented and schedule driven industry, construction projects are frequently subject to problems that constrain their execution. Since construction is a labour intensive industry, the shortage of labour has become the crucial risks that hindering the construction project in achieving sustainability. This paper, in reviewing the concept of sustainable construction, also addresses the influential factors concerning the labour shortages in the construction industry and discusses how these challenges can be managed in producing sustainable construction labours.
INCORPORATING WALKING IN TRAVEL TO WORK: THE MEANING OF COMMUTING FOR KUALA LUMPUR COMMUNITY
Authors: Adam Mastura , Abu Bakar Ahmed
Published: November 2016

Progressive increase in the influx of privately owned vehicles and a decrease in the modal share of public transport over the years become a city-based phenomenon. Over-dependence on cars encouraged a sedentary lifestyle, an obesity epidemic, social exclusion and increased carbon footprint. Deficiencies in urban planning have created a spatial separation between employment centres and residential areas. The research focused on investigating how people construct the meaning attributed to commuting mode of travel to work. Using multiple embedded case study research approach, this research focuses on 19 semistructured interviews with employees from two neighbouring but contrasting case study areas of Kuala Lumpur. Synthesis of the employees’ experiences on their travel behaviour exposed replication logic on the way they perceived walking as part of the transportation mode of travelling to work. The implicit understanding of the walking to work includes; definition of walking to work by the communities, specific walking stages and its’ characteristic during am-pm rush hours, the travel pattern and modes of transportation from the origin point (home) to the office, and the understanding of walking benefits to their economy, environment, health and social. These results provide possibility of understanding the needs of people and to promote walking to work as part of transportation mode for commuting in order to overcome the current urban challenges.

Pada edisi kali ini, Vol. IV No.1, Juli 2016, Jurnal Poetika secara spesifik mengangkat tema Gender sebagai bahan pembahasannya. Aspek penting dalam studi Gender tidak lepas sejarah pemikiran feminis abad ke-19 senantiasa berkutat pada relasi oposisi, yakni siapa yang berkuasa dan siapa yang mengalami opresi kekuasaan, juga pada relasi posisi—siapa subjek dan siapa objek. Perkembangan kehidupan sosial manusia memberikan pengaruh tersendiri pada perkembangan ideologi terkait gerakan feminisme itu sendiri. Feminisme radikal, liberal, sosial, agama, dll, menggambarkan adanya perbedaan dalam menanggapi kompleksitas perkembangan kehidupan. Perbedaan tersebut seakan mengembalikan satu keadaan dimana gerakan perempuan dipertanyakan ulang atas suara- suara perempuan yang diperjuangkan. Namun di sisi lain, hal tersebut juga menambah khazanah pengetahuan yang memunculkan gambaran-gambaran ketimpangan yang dialami oleh perempuan di berbagai aspek kehidupan. Melalui berbagai perspektif, enam tulisan dalam jurnal ini mencoba melihat secara mendalam wacana Gender dari banyak karya sastra.
Does the Prosperity Level of States Affect Participation in Trade Unions? A Quantitative Research
Authors: Giovanis Nickolaos
Published: November 2016

International differences in wage inequality remain a reality, despite efforts of negotiations and demands of the unions and contrary to the will of international organizations and associations for an international minimum wage. At the same time, the fall in wages and, specifically in minimum wages, combined with the decline of unionization are facts that seem connected.

This article presents the results of a quantitative research-using the Mann-Whitney non-parametric test and the linear bivariate correlation—which examines the potential connection between the Gross Domestic Product and union density in 33 member-states of the OECD, while examining the type of the correlation between them. The research results showed that high Gross Domestic Product is directly proportional to the size of union density and that there is a positive correlation between the two.
