Aspect-Oriented Modeling of Spatial Data Interpolation for Estimating Missing Data in Internet of Things (IoT) Service Discovery
Authors: Balakrishnan Senthil Murugan
Published: March 2019

The Internet of Things (IoT) is a model of future Internet and pervasive computing that has its own particular difficulties gained from the Internet as far as adaptability, vague topology, and so on are concerned. The proposed work means to determine the difficulties posed by IoT in the service discovery field. Most of the data analytics algorithms applied for data collected through sensors and actuators assume that the data are complete such that each property of the instances is filled with the appropriate value. These data have temporal and spatial correlation between them, and missing such data results in a significant decrease in accuracy and reliability of data analysis performed. Considering the importance of estimating the spatial data and the intricacies involved in estimating it using interpolation techniques, the proposed work bases its system development using an aspect-oriented programming improvement technique, thereby addressing the interpolation strategy as a cross-cutting aspect and reducing the complexity involved thereof. The proposal analyzes the situation of missing data and appropriately weaves the aspect and the application together, thereby decreasing the complexity in handling the interpolating data. The woven aspect estimates the missing data using an inverse distance weighting method and updates the information. Observation of the experimental results reveals significant improvement in response time compared with estimating the unknown value in a conventional manner.

Published: March 2019

Interpersonal problems are a core symptom of borderline personality disorder (BPD). This study investigated the relationship between emotion dysregulation, impulsiveness, and impaired mentalizing in the context of predicting interpersonal problems in BPD. A total of 210 patients with BPD completed the Difficulties in Emotion Regulation Scale (DERS), Barratt Impulsiveness Scale (BIS-11), Reflective Functioning Questionnaire (RFQ), and Inventory of Interpersonal Problems (IIP-32). The authors conducted three path models, with either mentalizing, emotion regulation, or impulsiveness as the exogenous variable. Emotion dysregulation and attentional impulsiveness predicted interpersonal problems directly, whereas hypomentalizing predicted interpersonal problems only indirectly throughout emotion dysregulation and attentional impulsiveness. The results suggest that these domains contribute significantly to interpersonal problems in BPD. Moreover, hypomentalizing might affect on interpersonal problems via its effect on impulsiveness and emotion regulation. The authors argue that focusing on emotion regulation and mentalizing in BPD treatments might have interlinked beneficial effects on interpersonal problems.

Published: March 2019

Este artigo relata a avaliação de um evento – “Encontros sobre o Poder Escolar” – organizado com o propósito de oferecer formação continuada a docentes da cidade de Pelotas (RS) e região. O evento tem crescido em tamanho e importância, ao longo dos anos, e apresenta um caráter diferente daquele dos usuais congressos e seminários voltados ao desenvolvimento de professores(as), organizados em torno de palestras de profissionais proeminentes e apresentações de pesquisas. O evento analisado, ao contrário, foca nas práticas dos(as) professores(as) e gestores(as), apresentadas por eles(as)  próprios(as) e discutidas, coletivamente, em Mesas de Apresentação. O artigo baseia-se em dados colhidos na nona edição do evento, ocorrida em 2009, centrando-se nas visões dos profissionais que nela apresentaram trabalhos. O instrumento de coleta foi o questionário, cujas respostas às questões precodificadas foram analisadas em termos de frequência. As respostas a uma questão aberta foram codificadas em categorias e também analisadas pelas frequências. Os resultados foram interpretados à luz das ideias de Vygotski, Freire e seus interlocutores e sugerem que o evento provocou, nos(as) docentes, o desenvolvimento de consciência sobre seu trabalho – a partir de reflexão, avaliação e discussões colaborativas – bem como empoderamento, pela valorização de suas práticas.
An ATF3-CreERT2 Knock-In Mouse for Axotomy-Induced Genetic Editing: Proof of Principle

Published: March 2019

Genome editing techniques have facilitated significant advances in our understanding of fundamental biological processes, and the Cre-Lox system has been instrumental in these achievements. Driving Cre expression specifically in injured neurons has not been previously possible: we sought to address this limitation in mice using a Cre-ERT2 construct driven by a reliable indicator of axotomy, activating transcription factor 3 (ATF3). When crossed with reporter mice, a significant amount of recombination was achieved (without tamoxifen treatment) in peripherally-projecting sensory, sympathetic, and motoneurons after peripheral nerve crush in hemizygotes (65–80% by 16 d) and was absent in uninjured neurons. Importantly, injury-induced recombination did not occur in Schwann cells distal to the injury, and with a knock-out-validated antibody we verified an absence of ATF3 expression. Functional recovery following sciatic nerve crush in ATF3-deficient mice (both hemizygotes and homozygotes) was delayed, indicating previously unreported haploinsufficiency. In a proof-of-principle experiment, we crossed the ATF3-CreERT2 line with a floxed phosphatase and tensin homolog (PTEN) line and show significantly improved axonal regeneration, as well as more complete recovery of neuromuscular function. We also demonstrate the utility of the ATF3-CreERT2 hemizygous line by characterizing recombination after lateral spinal hemisection (C8/T1), which identified specific populations of ascending spinal cord neurons (including putative spinothalamic and spinocerebellar) and descending supraspinal neurons (rubrospinal, vestibulospinal, reticulospinal and hypothalamic). We anticipate these mice will be valuable in distinguishing axotomized from uninjured neurons of several different classes (e.g., via reporter expression), and in probing the function of any number of genes as they relate to neuronal injury and regeneration.
Maladaptation of trout spermatozoa to fresh water is related to oxidative stress and proteome changes
Authors: Nynca J , Słowińska M , Judycka S , Ciereszko A
Published: March 2019

Rainbow trout sperm are ‘maladapted’ to freshwater spawning, resulting in shorter duration of sperm motility in fresh water compared to buffered saline solution. We hypothesized that different sperm motility-activating media have various effects on sperm motility characteristics and oxidative stress, as well as on the protein profiles of rainbow trout sperm. We designed an experimental model for activation of rainbow trout sperm motility in different osmotic conditions: (i) isosmotic and (ii) hypoosmotic. Spermatozoa activation with hypoosmotic solution was associated with lower values for sperm motility parameters (52%) and an induced increase in ROS level (19.4%) in comparison to isosmotic activation with isosmotic solution (67 and 9.5% for sperm motility and ROS, respectively). Hypoosmotic activation resulted in a higher number of differentially abundant sperm proteins (out of which 50 were identified) compared to isosmotic conditions, where only two spots of protein disulfide-isomerase 6 were changed in abundance. The proteins are mainly involved in the TCA cycle, tight and gap junction signaling, Sertoli cell–Sertoli cell junction signaling and asparagine degradation. Our results, for the first time, indicate that during hypoosmotic activation of sperm motility, osmotic stress triggers oxidative stress and disturbances mostly to structural proteins and metabolic enzymes. Our results strongly suggest that comparative physiological and biochemical analysis of rainbow trout sperm characteristics in isosmotic and hypoosmotic conditions could be a useful model for studying the mechanism of sperm activation in salmonid fish.

Gene drives could allow for control of vector-borne diseases by directly suppressing vector populations or spreading genetic payloads designed to reduce pathogen transmission. Clustered regularly interspaced short palindromic repeat (CRISPR) homing gene drives work by cleaving wild-type alleles, which are then converted to drive alleles by homology-directed repair, increasing the frequency of the drive in a population over time. However, resistance alleles can form when end-joining repair takes place in lieu of homology-directed repair. Such alleles cannot be converted to drive alleles, which would eventually halt the spread of a drive through a population. To investigate the effects of natural genetic variation on resistance formation, we developed a CRISPR homing gene drive in Drosophila melanogaster and crossed it into the genetically diverse Drosophila Genetic Reference Panel (DGRP) lines, measuring several performance parameters. Most strikingly, resistance allele formation postfertilization in the early embryo ranged from 7 to 79% among lines and averaged 42 ± 18%. We performed a genome-wide association study using our results in the DGRP lines, and found that the resistance and conversion rates were not explained by common alleles of large effect, but instead there were several genetic polymorphisms showing weak association. RNA interference knockdown of several genes containing these polymorphisms confirmed their effect, but the small effect sizes imply that their manipulation would likely yield only modest improvements to the efficacy of gene drives.

A Neurospora meiotic drive element known as Spore killer-2 (Sk-2) achieves biased transmission through sexual reproduction by killing siblings that inherit a competing allele...

Sk-2 is a meiotic drive element that was discovered in wild populations of Neurospora fungi over 40 years ago. While early studies quickly determined that Sk-2 transmits itself through sexual reproduction in a biased manner via spore killing, the genetic factors responsible for this phenomenon have remained mostly unknown. Here, we identify and characterize rfk-1, a gene required for Sk-2-based spore killing. The rfk-1 gene contains four exons, three introns, and two stop codons, the first of which undergoes RNA editing to a tryptophan codon during sexual development. Translation of an unedited rfk-1 transcript in vegetative tissue is expected to produce a 102-amino acid protein, whereas translation of an edited rfk-1 transcript in sexual tissue is expected to produce a protein with 130 amino acids. These findings indicate that unedited and edited rfk-1 transcripts exist and that these transcripts could have different roles with respect to the mechanism of meiotic drive by spore killing. Regardless of RNA editing, spore killing only succeeds if rfk-1 transcripts avoid silencing caused by a genome defense process called meiotic silencing by unpaired DNA (MSUD). We show that rfk-1’s MSUD avoidance mechanism is linked to the genomic landscape surrounding the rfk-1 gene, which is located near the Sk-2 border on the right arm of chromosome III. In addition to demonstrating that the location of rfk-1 is critical to spore-killing success, our results add to accumulating evidence that MSUD helps protect Neurospora genomes from complex meiotic drive elements.

Authors: Amirmudin Noor Amirah , Lavelle Grace , Theologis Tim , Thompson Nicky , Ryan Jennifer M.
Published: March 2019

CONTEXT:

Multilevel surgery (MLS) is standard care for reducing musculoskeletal disorders among children with spastic cerebral palsy (CP).

OBJECTIVE:

To summarize the literature examining effects of MLS and satisfaction with MLS for children with CP.

DATA SOURCES:

Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials were searched.

STUDY SELECTION:

Studies in which authors reported effects of or satisfaction with MLS in children with CP were selected.

DATA EXTRACTION:

Two authors screened and extracted data on gross motor function, gait speed, gait (eg, Gait Profile Score), range of motion, strength, spasticity, participation, quality of life, satisfaction, and adverse events.

RESULTS:

Seventy-four studies (3551 participants) were identified. One was a randomized controlled trial (RCT) (n = 19); the remainder were cohort studies. Pooled analysis of cohort studies revealed that MLS did not have a long-term effect on gross motor function (standardized mean difference [SMD]: 0.38; 95% confidence interval [CI]: −0.25 to 1.01) or gait speed (SMD: 0.12; 95% CI: −0.01 to 0.25) but did improve gait (SMD: −0.80; 95% CI: −0.95 to −0.65). The RCT also revealed no effect of MLS on gross motor function but improvements in the Gait Profile Score at 1 year. Participation and quality of life were reported in only 5 studies, and adverse events were adequately reported in 17 studies.

LIMITATIONS:

Data were largely from cohort studies.

CONCLUSIONS:

Findings reveal that gait, but not gross motor function, improves after MLS. RCTs and improved reporting of studies of MLS are required.
GENESIS OF OLD BELIEVERS ANTHROPOLOGY
Authors: Parilov Oleg V. , Shaposhnikov Lev E.
Published: March 2019

Introduction. The modern globalized postmodern consumer society, total game simulation, colossal disconnection is extremely destructive for the individual. The Old Believer outlook, which affirms the soborn-person, attached to the fundamental foundations of the national religious culture, the bearer of higher transcendent meanings, acquires a particular urgency today. Accounting for both positive and negative experience of Old Believer anthropology will allow to determine the ideal of an integral convinced person who overcomes the extremes of conformism and fanaticism. Materials and Methods. The article is prepared on the basis of the original works of the Old Believer authors; pre-revolutionary, Soviet, modern Russian and foreign studies of Russian culture and the Old Believer worldview. The methodological basis was: a civilizational approach to history, methods of hermeneutics, comparative-historical, the unity of historical and logical, analysis, synthesis, analogy. Results of the study. The article deals with socio-cultural, spiritual factors of the borderline era of the 17th century, under the influence of which a unique Old Believer anthropology is formed, reflecting the worldview characteristics of the Russian Middle Ages and Russia of the new time. The dynamics of Old Believers’ views on man during the XVII–XX centuries is investigated; revealed spiritual, historical reasons for the transformation of the anthropological views of the Old Believers. Discussion and Conclusion. It is established that the early Old Believers, as representatives of the medieval people’s Orthodox consciousness, affirm a person of a sacral, conciliar, but individually immature. However, under the influence of modern trends, Old Believer gives rise to the idea of the charismatic personality of the Old Believer apostle. For the Old Believers of modern times, anthropocentric tendencies, significant existential interest, exaltation of man as the Image of God, especially his reasonable abilities, are characteristic. But due to the self-consciousness of the last defenders of Holy Russia, the guardianship, the Old Believers miss the fact of the damage to human nature, underestimate the need for spiritual development.

The impact of exposure to wagering advertisements and inducements on intended and actual betting expenditure: An ecological momentary assessment study
Authors: Browne Matthew , Hing Nerilee , Russell Alex M. T. , Thomas Anna , Jenkinson Rebecca
Published: March 2019

Background and aims

Research suggests that a large proportion of regular sports and race bettors experience harm related to their gambling. In Australia, people who bet regularly are targeted by a proliferation of different forms of inducements and advertising – many of which are believed to encourage excessive betting and erroneous perceptions of risk. However, scant research has examined the impact of marketing messaging to this group, which is also limited to cross-sectional or qualitative designs. We aimed to determine whether exposure to wagering advertisements and inducements influenced intended betting expenditure, actual betting expenditure, and spending more than intended.

Methods

We report on an ecological momentary assessment study, measuring regular exposure to 20 different forms of marketing, as well as wagering spend from 318 race bettors and 279 sports bettors. Up to 15 assessments per participant were conducted over 3 weeks (mean = 11.46, median = 14), yielding 6,843 observations for analysis.

Results

Exposure to advertising and inducements was reliably linked to a greater likelihood of betting, higher intended and actual betting expenditure, and spending more than intended. “Push” messaging and inducements that convey the impression of reduced risk (stake-back inducements and multibet offers) were particularly influential, as well as brands promoted during events and advertisements on betting websites/apps.

Discussion and conclusions

Given that a large proportion of regular sports and race bettors experience problems, restrictions on these forms of marketing are advisable. These findings suggest that this is particularly important for marketing that is “pushed” to gamblers or that suggests reduced risk.
The “ABCDE” of video gaming control: Arguments, basic research, conceptual models, documented lessons, and evaluation
Authors: Daniel T. L. Shek
Published: March 2019

This commentary responds to the review conducted by Király et al. (2018). The review enlightens and is useful in view of the limited studies on problematic use of video games and related control policies. It is argued that when considering regulation policies on video games, reference should be made to the arguments involved (A), basic research (B), conceptual models on problem video game use (C), documented lessons learning the broad field of addiction (D), and the need for rigorous evaluation (E). Besides “supply” reduction, it is vital to look at “demand” reduction in terms of how inner strengths may help to reduce the problematic use of video games.
The effect of foreign direct investment on firm labor productivity: Does the country of origin of the FDI matter?
Authors: Tőkés László
Published: March 2019

Many papers have analyzed the effects of foreign acquisition on firm productivity, articulating its positive impacts. However, an important issue remains: is there a general foreign acquisition effect, or is there any heterogeneity in the effects? This paper reports on the analysis of over 3,400 majority foreign acquisitions in Hungary. The main result (which exists in a propensity score matching sample as well) of the difference-in-differences analysis is that only acquirers from higher income countries foster labor productivity significantly — and this effect increases with the income gap between Hungary and the country of origin -, while acquirers from lower income countries do not induce statistically significant effects.

Analysis of and Feedback for Free-Form Answers in English and Romanized Japanese
Authors: Yoshii Rika , Milne Alastair
Published: March 2019

This paper describes a powerful answer analysis system which solves the difficult problems of recognizing student reproductions of spoken Japanese sentences. It allows all reasonable Roman spellings of Japanese words, while at the same time detecting mishearings, and distinguishing between important and unimportant spacing errors. The system can handle combinations of these errors while detecting incorrect word orders and missing sentence parts, and determining the semantic category into which the student answer falls. For each Computer Assisted Language Learning (CALL) system it is used with, the specification of answer categories and requests for error checks are contained in a database separate from the program. The system has been used successfully for answer analysis in listening comprehension exercises.

Authors: Herron Carol , Dubreil Sebastien , Cole Steven P. , Corrie Cathleen
Published: March 2019

This investigation examines whether foreign language (FL) students learn cultural information embedded in videos. Fifty beginning French students participated. They viewed eight targeted videos as part of their multimedia-based curriculum. A pretest and a posttest assessed long-term gains in overall cultural knowledge and in the learning of little "c" culture (practices) and big "C" culture (products). Eight postvideo tests measured short-term retention of culture in each of the eight videos. Oral dialogues tested students' ability to interact culturally appropriately in a communicative setting. A questionnaire analyzed student perceptions of cultural learning. From pre- to posttesting, results indicated a significant gain in overall cultural knowledge. Posttest scores were significantly higher than pretest scores. Pretest and posttest scores were significantly higher for little "c" than for big "C." On the postvideo tests, measuring short-term retention of culture, there was no significant difference between types of culture retained. Regarding oral performance, students performed culturally appropriately more than 60% of the time. Students perceived that the videos contained more little than big "C" culture and that they learned more little "c." Results support using video an effective technological tool for presenting culture in the FL classroom.

Published: March 2019

The bacterial gdhA gene encodes NADH-GDH enzyme. The gdhA-transgenic tobacco plants exhibited high growth performance and enhanced herbicide resistance as well as drought tolerance. In addition, the gdhA gene when expressed in maize plants could increase productivity because of improving stress tolerance. In this study, we isolated and analyzed a gdhA gene from the E. coli strain JM109. Then, the E.coli derived-gdhA sequence was modified by using OptimumGene™ software for plant compatibility. The optimized gdhA gene was inserted into an expression cassette containing the CaMV 35S promoter and the 35S terminator of the pRTRA7/3 vector. The 35S::gdhA::35S construct was ligated into the plant expression plasmid pCAMBIA1300 which then introduced into the A. tumefaciens strain EHA105. In order to examine the expression of the gdhA gene, we created gdhA-transgenic plants via Agrobacterium-mediated transformation into N. tabacum K326. The PCR analysis showed that two out of 20 plants were positive to the presence of the gdhA gene. The RT-PCR experiment also revealed that gdhA was expressed in transcriptional level. These results suggested that the gdhA expression construction can be transformed into other crops such as maize.

As an English teacher in the era of industrial revolution 4.0 it is hoped that a teacher is able to apply any kinds of teaching media to create the teaching and learning atmosphere joyfully and to support in gaining the teaching and learning objectives effectively.  There are numerous teaching media based on technology. One of them is Orai Application that is applied in teaching and learning of English especially speaking fluency. Today, all graduates face a world transformed by technology, in which the Internet, cloud computing, and social media create different opportunities and challenges for formal education systems. Higher education in the fourth industrial revolution is a complex, dialectical and exciting opportunity which can potentially transform society for the better. The fourth industrial revolution is powered by artificial intelligence and it will transform the workplace from tasks based characteristics to the human centred characteristics. This paper is aims to explore the use of Orai application in classroom teaching speaking in assisting student’s speaking fluency.
IMPROVING STUDENTS’ ENGLISH-SPEAKING SKILLS THROUGH BEHAVIOUR MODIFICATION IN INDONESIAN ISLAMIC BOARDING SCHOOLS
Authors: A Izzuddin
Published: March 2019

A number of modern Islamic Boarding Schools (IBS) have long implemented a unique English Language Teaching (ELT) strategy in improving their students’ English-speaking skills. In IBS, for example, head of language department requires the students to communicate in English in daily activities, and punishment is imposed to those who do not speak English. However, there was no specifically academic term used to describe such strategy, nor was there a study to investigate the effectiveness of the strategy. This essay investigates what IBS-applied ELT strategy is, and to what extent it is effective in improving speaking skills of the students. It is found that IBS has made use of a behaviour modification as ELT strategy. The behaviour modification is able to encourage students to communicate in English in their daily activities. It also leads students to acquire accuracy, complexity and fluency in speaking.
THE USE OF PICTURE TO IMPROVE STUDENTS’ SPEAKING SKILL IN ENGLISH
Authors: Nurdini Rahmi Aulia
Published: March 2019

This study is aimed to investigate how to teach English speaking or conversation interestingly for students by using a picture so that the students are easier to learn and enjoy in speaking English to others in the classroom. Method employed was descriptive qualitative method by doing observation and library research. Findings shows that using picture is one of good way to create an interesting learning process, so the students can easier to understand the lesson, and get enthusiastic to speak English to others in the classroom. Finally, if student always practice it repeatedly even out of the class, they will be able to remember permanently what they had learned and they will improve their ability in speaking English automatically.
Synthesis of nanocapsules using safflower oil for self-healing material
Authors: Bagale Uday D , Sonawane Shirish H
Published: March 2019

The present work deals with the synthesis of nanocapsules containing an edible oil and corrosion-inhibiting component. Safflower oil is encapsulated in urea–formaldehyde polymeric shells using an ultrasound-assisted in situ polymerization approach. Safflower oil is an edible and semi-drying oil with a high polyunsaturated fat content. The particle size of the prepared nanocapsules is analyzed using a transmission electron microscope. Subsequently, the prepared nanocapsules are incorporated in epoxy–amine to develop a self-healing corrosion-inhibiting coating. The performance of the coating is evaluated based on studies involving the healing mechanism for the coating. Corrosion inhibition of healed areas has been evaluated using electrochemical impedance spectroscopy (EIS), Tafel plot and immersion test, considering standard epoxy–amine coating as the standard. The obtained results confirmed better corrosion protection in terms of the EIS data and Tafel plots. It was found that the current density decreases from 0·00021 A/cm2 (for the standard epoxy coating) to 4·79 × 10−9 A/cm2 with the addition of 2·5 wt% nanocapsules in the coating.
The prey-stage preferences of Amblyseius swirskii Athias-Henriot and Neoseiulus californicus (McGregor) (Mesostigmata: Phytoseiidae), between egg and nymph stages of Tetranychus urticae Koch (Trombidiformes: Tetranychidae)

Tetranychus urticae Koch
(Trombidiformes: Tetranychidae), two-spotted spider mite, is a pest mite
species that feed on a wide range of plants around the world. Neoseiulus californicus (McGregor)
(Mesostigmata: Phytoseiidae) is shown as a predatory mite to be a very
efficient biological control agent of T.
urticae. Amblyseius swirskii
Athias-Henriot (Mesostigmata: Phytoseiidae) is another phytoseiid mite species which
can feed and reproduce on a wide range
of food sources, including T. urticae. Information about the prey
stage preference of a predator is valuable for evaluations of the potential of
predatory mites to control of pests. We therefore analyzed the prey-stage
preferences of A. swirskii and N. californicus to eggs and nymphs of T. urticae at 15:15, 10:20, and 20:10
egg: nymph ratios under controlled conditions (25±1 °C, 65±5% RH and 16-h light: 8-h dark photoperiod). The experiment
was carried out on abaxial surfaces of bean
leaf discs with a diameter
of 2 cm. Starved (for 24 h), 2-3
days-old gravid females of A. swirskii
and N. californicus were used in the
experiment. One predatory mite was placed individually on each bean leaf disc infested with 15:15, 10:20 and
20:10 ratios of T. urticae egg: nymph. After 24 h of feeding, the
numbers of prey consumed for each prey stage were recorded. From the results,
it is clear that while N. californicus
showed no preference between egg and nymphs of T. urticae. A. swirskii
preferred nymphs to eggs of T. urticae.
A Bayesian Parameter Estimation Approach to Response Surface Optimization in Quality Engineering
Authors: Kozan Elif , Köksoy Onur
Published: March 2019

ABSTRACT

In
recent years, Bayesian analyses have become increasingly popular for solving
industrial related problems. This paper illustrates the use of Bayesian methods
in response surface methodology (RSM) in the context of “off-line quality”
improvement. Bayesian linear regression uses the prior information in the high
uncertainty state of the response function to make more efficient and more
realistic inferences than can be obtained with classical regression. Several
different models of parameter estimation and uncertainty analysis will be
presented for comparative purposes. An example illustrates the findings.
Metallographic Aspects Investigation of Penstock Materials in Hydroelectric Power Plants and Penstock Maintenance Methods

Hydroelectric power
plants are renewable energy sources and have little impact on the environment.
Therefore, it is one of the most preferred energy sources in the world. In
parallel with this situation, it is very important that the hydroelectric power
plants are maintained, their failures are prevented or permanently removed. One
of the most important parts of hydroelectric power plants is penstock pipes.
Along with the snail part of the power plant, the penstock supplies the
pressurized water to the turbine wheel for energy production. In the power
plants that have been producing energy for many years, the maintenance and
material properties of penstock are very important. In this study, one of the
most important equipment of hydroelectric power plants, pressurized water pipes
(penstock) and chemical components have been examined in macro and micro
structure and their maintenance is investigated. In the metallographic study on
the samples taken from two different regions of the penstock pipe; the perlitic
structure, which has a homogeneous distribution into the ferritic structure
forming the matrix, is determined and supported by analyzes. This study will
help to ensure that all hydroelectric power plants operate smoothly in terms of
penstock.
Do Greasy Wheels Curb Inequality?
Authors: Doniger Cynthia L.
Published: March 2019

I document a disparity in the cyclicality of the allocative wage-the labor costs considered when deciding to form or dissolve an employment relationship-across levels of educational attainment. Specifically, workers with a bachelors degree or more exhibit an allocative wage that is highly pro-cyclical while high school dropouts exhibit no statistically discernible cyclical pattern. I also assess the response to monetary policy shocks of both employment and allocative wages across education groups. The less educated respond to monetary policy shocks on the employment margin while the more educated respond on the wage margin. An important takeaway is that conventional monetary policy easing reduces employment inequality but increases wage inequality. I embed these findings in a New Keynesian framework that includes price and heterogeneous wage rigidity and show that heterogeneity results in welfare losses due to fluctuations that exceed those of the output-gap and p rice-level equivalent representative agent economy. The excess welfare loss is borne by the least educated.
