The sensitivity of turbine cascade endwall loss to inlet boundary layer thickness
Authors: Coull John , Clark Christopher , Vazquez Raul 
Published: March 2019

The development of hub and casing boundary layers through a turbomachine is difficult to predict, giving rise to uncertainty in the boundary conditions experienced by each blade row. Previous studies in turbine cascades disagree on the sensitivity of endwall loss to such inlet conditions. This paper explores the problem computationally, by examining a large number of turbine cascades and varying the inlet boundary layer thickness.It is demonstrated that the sensitivity of endwall loss to inlet conditions is design dependent, and determined by the component of endwall loss associated with the secondary flow. This Secondary-Flow-Induced loss is characterised by a vorticity factor based on classical secondary flow theory. Designs that produce high levels of secondary vorticity tend to generate more loss and are more sensitive to inlet conditions. This sensitivity is largely driven by the dissipation of Secondary Kinetic Energy (SKE): thickening the inlet boundary layer causes the secondary vorticity at the cascade exit to be more dispersed within the passage, resulting in larger secondary flow structures with higher SKE. The effects are captured using a simple streamfunction model based on classical secondary flow theory, which has potential for preliminary design and sensitivity assessment.

Abstract
Every new policy by Indonesian government in National Examination (NE) implementation always obtains different respond from public. Since the implementation, NE system already experienced many changes, but in recent years this system receives serious critiques. As a result, government then abolished this system as graduation determinant in 2014. This research analyzes public opinion, in the form of positive and negative sentiment toward NE policy, and factors that drive the opinions. Data in this research obtained from online news media from 2012 to 2015. The result shows that public sentiment fluctuating from year to year and depends on three important factors, i.e. political pressure, extreme events, and media coverage.

Impact of windstorm on a community of centipedes (Chilopoda) in a beech forest in Western Poland
Authors: Leśniewska Małgorzata , Skwierczyński Filip 
Published: March 2019

AbstractThe study was carried out in the years 2016–2017, five years after a windstorm which destroyed 1/3 of the protected beech forest area in the west of Poland. The community of centipedes in the area affected by the windstorm was depleted in terms of the species richness, diversity, and population density. The dominance structures were shortened and the species composition was rebuilt. The areas that proved to be the richest in terms of species richness and diversity among the sites affected by the windstorm were the one where windfallen trees were left and the other where beech trees had been planted by humans. In total, the quantitative and qualitative samples collected four times throughout a year featured 608 specimens from 11 species of two centipede orders – Lithobiomorpha and Geophilomorpha.Lithobius curtipesandL. forficatuswere found in all of the investigated areas.L. pelidnusandL. piceuswere captured at control sites exclusively. Only one species –L. erythrocephaluswas found solely at the damaged site. The most numerous and most frequently found species in the community wereL. curtipes,L. mutabilis, andStrigamia acuminatarespectively. Although windstorms are natural phenomena their consequences may lead to significant changes in the community of the investigated soil animals. The importance of coarse woody debris, significantly contributing to the improvement and maintenance of species richness and diversity of Chilopoda, has once again been confirmed.
Media Education in Slovene Preschools: A Review of Four Studies
Authors: Rek Mateja 
Published: March 2019

In Slovenia, the concept of media literacy has been integrated into the formal education system, including early childhood education. The Preschool Curriculum sets certain goals to be followed in educating preschoolchildren on media-related topics. Research done in other Member States of the EU points to the conclusion that the actual implementation and delivery of media education is both fragmented and inconsistent as well asdependent on the interests and motivation of individual preschool teachers. They are the ones who, in accordance with their professional capacity and autonomy, include the goals set in the curriculum into an actuallearning process in preschools, also determining the timing and manner of this. The aim of this article is to review, compare, and analyse the data from recent research on the media education of preschool children in Slovenia in order to better understand how preschool teachers in Slovenia assess their capacity to work with media as well as their media literacy levels, which media they use, and how the media education is conductedin the groups of preschool children.
A review of pollinator conservation and management on infrastructure supporting rights-of-way
Authors: Wojcik Victoria Agatha , Buchmann Stephen 
Published: March 2019

Early successional landscapes along or adjacent to infrastructure installations have been highlighted as potential pollinator conservation zones that provide environmental benefits and ameliorate some of the negative impacts of wildland conversion. Habitat development and management initiatives in this field are active, but vetted support for particular techniques and strategies is lacking and technical information is diffuse. We reviewed the current scientific and technical literature relating to right-of-way and roadside management to produce an overview. Surveys and comparative studies dominate the literature, with limited manipulative experimentation and limited tests of best management practices. Local floristic diversity is shown to be a determinant of butterfly, bee, and fly patterns but data is almost entirely lacking on vertebrate pollinators. The degree to which these linear landscape corridors can promote movement and connectivity is also not well addressed, yet there is a focus in the conservation community to promote migrations and movement. Contrasting results are reported for the impact of disturbance regimes associated with management (mowing and herbicide use), and there is also only minimal attention given to the potential negative impacts that are experienced by pollinators on rights-of-way. Even with the limited literary accounts of pollinator management in these landscapes we believe infrastructure landscapes can provide substantial benefits to pollinator species and ecosystem services and encourage further management-based investigations.

Hummingbirds at artificial flowers made to resemble ornithophiles versus melittophiles
Authors: Guzman Wyndee A. , Wilson Paul 
Published: March 2019

Certain floral characteristics are associated with specific pollinators. Hummingbird-pollinated flowers are usually red, lack a landing platform, lack nectar guides, and contain a high amount of dilute sucrose-rich nectar. Here we test hypotheses concerning the reasons for these characters to the extent that they involve hummingbird responses. An array was set up of 16 artificial plants, each with five artificial flowers. (1) Flowers made to differ only in colour elicited a slight preference for red. (2) When colour was associated with nectar offerings, and birds generally learned to visit flowers that provided much more nectar but did not associatively learn differences as little as 2 µL. (3) Birds were offered 8 µL of 12% sucrose versus 2 µL of 48% hexose, and they did not prefer the dilute nectar; they showed no evidence of discerning sucrose from hexose; however, they preferred 48% over 12% sucrose when both were offered in the same quantity. (4) Birds preferred flowers that lacked landing platforms over those with landing platforms. (5) Birds were offered flowers with nectar guides, associated with differing nectar volumes, and they did not associate the higher nectar reward with either flower type. In summary, the feedback from hummingbirds reflects some of the differences between bird- and bee-adapted flowers, but nectar seemed less predictive than expected. Factors other than the behavioural proclivities of hummingbirds, such as adaptation to discourage bees, are discussed as additional causes for the differences between the syndromes. We also discuss significance testing for field experiments involving one unreplicated array. Editors’ comment: The authors and reviewers disagreed about some aspects of the experimental design (e.g. necessity of marking of individual birds) and how the data should be treated (e.g. analysing only first visits versus including all data). On balance the editors decided that publication of this study gives readers the opportunity to make up their own minds about the results as presented.

Published: March 2019

This study explores how work to family conflict, family to work conflict, work to family enrihcment and family to work enrichmetn influence facultyâ€™s global balance measured as satisfaction with work family balance (SWFB). In addition the multiplicative interactive effect of work to fmaily conflict with enrichment and family to work conflict and enrichment were also tested. Results revealed that work to family conflict and enrichment, their interaction and family to work enrichment were significantly related to SWFB. Work to family conflict was most potent predictor of outcome variable but there is a need for managers to improve facultyâ€™s percepteion of work interfering with family. Both directions of enrichment had high levels but their importance was moderate while family to work conflict was very low in importance requiring minimal managerial interventions. Multi group analysis revealed no significant difference between male and female faculty.

Published: March 2019

Financial Inclusion lays an important role in developing and expanding financial markets. In the last decade, Balkan economies seem to have incensed to progress the deliberation of the financial inclusion and integrate the international financial market into their home financial system and subsequently achieve more escalation economically. Unfortunately, there has been observed small attention specified to the acceptance of recognized financial inclusion, particularly, how the shadow economy and financial outreach influence the financial inclusion. The present study checks and measures the strength and degree of control that shadow economy generate on financial inclusion on the one side, and on the other side it also process, approximate and investigate empirically that how the financial outreach affects financial inclusion in the six selected economies for the purpose of this study. To accomplish the objectives of the study time frame of 2006-2017 was taken for data compilation and investigation. Asymmetrical co-integration approach is used, which commence non-linearity in the measurement of model. The contemporary nonlinear approach co-integration (i.e., NARDL) is used. The results of the study advocate that for Balkan countries it is vastly noteworthy to handle and organize the concerns of financial inclusion flanking the shadow economy size connected challenges. It entail wide-ranging review of existing and potential modification programs that may create accurate use and allotment of financial services products. It may escort to income equality and poverty alleviation. Furthermore the strategy formulation agencies in these economies need to stamp out hindrance to such financial inclusion through quality convenience of financial services products in a satisfactory way. This will convey into stream those underprivileged and economically mislaid firms and households which were earlier someway incapable to donate in the economic improvement. This inclusion as a result will enhance expansion of financial markets and economy leading to in general development of such economies.

Published: March 2019

BACKGROUND: Adequate participant’s fixation affects measurement accuracy and performance of isokinetic exercise. OBJECTIVE: To examine the effects of different fixation methods and contraction modes on the kinetics and 3D kinematics of prone isokinetic knee flexor tests. METHODS: Fourteen healthy male participants performed maximal unilateral concentric and eccentric knee flexion movements with minimal (hand grips), moderate (grips, hip strap) and maximal (grips, thigh and hip strap, hip wedges, shoulder pads) fixation at 30[Formula: see text]/s. RESULTS: Concentric and eccentric peak moments were highest at minimal and maximal fixation, whereas contractional work peaked at minimal fixation. Axis alignment was best at moderate fixation. Initial axis alignment caused an average antero-cranial shift (2.0 and 0.1 cm) as well as mean roll and yaw angle tilts of [Formula: see text]0.1[Formula: see text] and [Formula: see text]6.1[Formula: see text]. Hip motion was significantly reduced at maximal fixation. Eccentric movements demonstrated a lower mean angular velocity (26.0[Formula: see text]/s) than concentric tests (29.4[Formula: see text]/s). CONCLUSIONS: Depending on their purpose, prone isokinetic knee flexor tests or training sessions should be conducted with minimal (maximal force production) or moderate (axis alignment) fixation. When interpreting and comparing isokinetic results, the examined kinematic and kinetic effects of different fixation methods should be taken into account.
