SKILL MISMATCH DAN UPAYA MENGATASINYA (Studi pada 3 hotel di Semarang)
Authors: Dwiatmadja Christantius , Pravitasmara Dewi Yustina Erti
Published: June 2019

This study aims to explain how to overcome the employee skill mismatch that works with the company. The research was conducted at the hotel because of the high of its business competition and the gap between the number of hospitality education institutions and the number of hotels in operation that had consequences for the occurrence of skill mismatch. The findings of a previous study of skill mismatch concluded that there was a disruption in competitiveness and productivity in companies using employees with skills and education gaps. Using a multi-case study technique, data collection was carried out in five-star hotels, three-star hotels and one-month period June-August 2018 in Semarang. The results of the study show that the effort to overcome the mismatch skill in the company is to conduct employee learning. There are differences in the learning process of employees in overcoming skill mismatch, where the higher the star classification in the hotel business the higher the involvement of the company. In other words, the smaller the classification of hotel stars, the individual efforts of employees to learn to overcome the mismatch skill is also greater. Based on these findings, this study uses the learning organization theory as a frame of mind and analysis.

One of approach used in knowledge asset (knowledge property/asset) assessment and measurement was Intellectual Capital that comprised of 3 main elements of Human Capital, Structural Capital, and Relational Capital. Creative industry is industry with uniqueness and put more emphasize on creativity, innovation and individual talent utilization require maximum management. This research intended to find model, on how correct intellectual capital component would be, and find actual description of Human Capital, Structural Capital as well as Relational Capital principles for creative industry in East Java. Samples in this research were leader/management/owner of 5 creative industry sub-sectors in 9 cities of East Java (Surabaya, Pasuruan, Probolinggo, Mojokerto, Batu, Malang, Kediri, Blitar, and Madiun) with 45 people respondents as samples. Analysis technique utilized in this research was Spider Plot Diagram. Survey and discussion result showed that Intellectual Capital Mapping on 5 (five) creative industry sub-sectors in East Java demonstrated that Relational Capital was more dominant followed by Human Capital, and Structural Capital as the least dominant.
Authoritarian state building through political decentralization and local government law
Authors: Tajbakhsh Kian
Published: June 2019

What motivates ideological authoritarian regimes to permit subnational elections? What mechanisms do these regimes employ to ensure that local electoral outcomes are favorable to the regime? Focusing on the decision to create a new tier of elected local government and the use of local government law, I argue that national elites can use local elections to strengthen state-building through increased institutionalization of mass political participation and by integrating local populations into the ambit of state controlled public goods provision. I illustrate this argument by analyzing elected local government in the Islamic Republic of Iran. I show how the state’s legal framework successfully constrains local actors in three contested domains: the scope of political participation, the extent of legislative authority, and the degree of fiscal autonomy. A major implication of these findings is that expanding participation through subnational elected government in an ideological Islamist regime contributes to authoritarian nation-state building.
The Voice Is the Message
Authors: Schnädelbach Sandra
Published: June 2019

This paper illustrates that emotions were considered a central component of juristic work in German legal thought around 1900, showing how emotional practices of judges were reshaped when they were confronted with new socio-political demands in the early 20th century. It argues that judicial emotions were intensely reflected upon and used by German jurists, especially via court rhetoric and specific politics of voice. It puts forward an understanding of vocal performances as emotional practices that became particularly contested during the first decades of the 20th century. Whereas classical ideals of judicial conduct placed a premium on authority and distance in order to ensure objectivity, a psychologically informed and emotion-based interaction between judges and court attendees came to the fore: the use of rhetoric and the ability of showing, forming, and creating emotions gained relevance. The judge was not only to manage his own emotions, but was conceived of as an active engineer of emotions in court.
A Sociological Perspective on Emotion Work and Judging
Authors: Roach Anleu Sharyn , Mack Kathy
Published: June 2019

Judicial work requires judicial officers to manage their own emotions and related conduct, as well as to anticipate, interpret, respond to and manage emotions and behaviours of others, most visibly in the interaction order of the courtroom. A detailed, sociological analysis of judicial interview data reveals the ways judicial officers themselves understand, manage and use emotion in their everyday work. Judicial emotion work is more than a purely individual or personal enterprise. It operates in accordance with explicit and implicit feeling and display rules, cultural scripts and legal norms that shape the relation between emotion and judging. The ways judicial officers articulate their understanding of emotion in their everyday work reveals their reproduction and potential transformation of the boundaries between emotion and their status as judge. These findings reposition emotion work as central to judicial performance and enable emotion itself to be recognised as a positive judicial resource.
Combating destabilising forces in modern operations. Research report
Authors: Więcek Wojciech
Published: June 2019

Undertaking to determine scientifically substantiated conditions for the functioning of destabilising forces and methods for countering them in contemporary operations fits in the broad scope of security. This paper reports the results of the study that employed survey methodology to investigate the matter of destabilising forces in order to provide the contribution to the current body of literature in the field. Recently published scientific and non-scientific studies in Polish and English on destabilising forces, despite the semantic differences, refer to a large extent to the problem of acting and combating such groups. The paper puts forward a series of conclusions and proposals with the intention of inspiring the critical evaluation and to encourage substantive polemics in the pages of specialist scientific periodicals. This material may serve as the basis for further detailed research into destabilising forces – the subject that is not only a pressing current issue, but above all a prospective area for research as part of the security sciences.
CORPORATE SOCIAL RESPONSIBILITY (CSR) AND LEADERSHIP: VALIDATION OF A MULTI-FACTOR FRAMEWORK IN THE UNITED KINGDOM (UK)
Authors: Khattak Shoukat Iqbal , Jiang Qingquan , Li Hui , Zhang Xiaosan
Published: June 2019

Global surveys indicate that employee engagement costs nearly £70 billion per year in the UK alone with nascent improvement from 2011 to this date. Recognising employee disengagement as a threat to global socio-economic sustainability, experts and scholars offer CSR and employee-centric leadership as practical solutions. Visionary and servant leadership incite superior employee efforts through fair and ethical work values, but past theory and research show limited research on micro-processes that link CSR to employee outcomes. This study tested a value-centered model to examine if the two leadership styles and overall fairness can explain the positive relationship between CSR and extra effort. Data analysis of 512 employee self-reports using the structural equation modelling (SEM), the PROCESS approach and other techniques showed that executive’s CSR values cue to employee visionary and servant leadership, which influence extra effort both directly and indirectly (through overall fairness). Even though employees strongly endorsed the positive influence of universal visionary prototype, overall fairness was more strongly perceived in servant leadership. The paper offers practical implications for organizational theorists and practitioners.

Caught in the concept jungle: developing a format for data contributions to the World Flora Online
Authors: Berendsohn Walter G. , Miller Chuck , Ulate William , Watson Mark
Published: June 2019

The World Flora Online initiative (www.worldfloraonline.org) is a global consortium of many of the world’s leading botanical institutions with the aim to offer a worldwide information resource for plant information (Miller 2019). It aggregates information provided by the botanical community, either through specialized information systems or published taxonomic treatments and floras. WFO distinguishes contributions to the Taxonomic Backbone (i.e. the community-curated consensus system of scientific names, taxa, synonyms and their classification) from Content contributions (i.e. descriptive data, images, distribution, etc.). In the course of writing the guidelines for contributors, a format for the electronic submission of these data had to be developed. The expectation was that this would be a comparatively simple task, drawing on existing TDWG standards and using established formats and tools, i.e. Darwin Core Archive, the Integrated Publishing Toolkit and the DwC-A Validator tool. Actually, it was not that simple, as several problems had to be solved. First of all it was somewhat difficult to find authoritative sources on the web for existing data definitions. That solved, the actual definitions were, in some cases not really adequate for use by the botanical community, or a narrower description had to be given, or our portal software (based on the eMonocot portal system developed by the Royal Botanic Gardens, Kew) required a different controlled vocabulary. A decision was taken to follow the DwC naming conventions for data elements, although in some cases the designations - or at least the applications in a checklist context - were patently wrong (e.g. “taxonID” as the identifier for names, including synonyms). For Content contributions, the DwC-A standard star schema was useful, but it was not appropriate for backbone contributions with their multiple relationships e.g., to literature references. This experience underlines the necessity for a coherent documentation of standards (see Blum et al. (2019)), including user-friendly access to definitions, data validation tools and clear guidelines for extensions/subtyping also at the element-level.

The energy industry is identified as a growing business area and the target of development in a case study region. This practitioner’s report describes how the regional energy cluster was defined by using the wind power cluster framework as a basis. The identified energy industry players are positioned in the wind power cluster framework and the actors and operating environment are described and analyzed. According to this study the cluster framework can be a basis for cluster definitions of other industries, especially in the same case region. The practical object of the study is to give regional officials a clear picture of the energy industry operating environment and its cooperation network.
« Naturellement, entrez, entrez ! »
Authors: Terestchenko Michel
Published: June 2019

L’action altruiste en faveur des Juifs dont ont fait preuve le pasteur André Trocmé et son épouse Magda au Chambon-sur-Lignon pendant la Seconde Guerre mondiale jaillissait spontanément du plus profond de leur être comme une obligation à laquelle ils ne pouvaient se soustraire, porteuse sans doute de dangers considérables mais qui n’avait rien de sacrificiel. En agissant ainsi, ils ne renonçaient pas à leur être et à leurs intérêts profonds : ils y répondaient, tout au contraire, dans une parfaite conformité et fidélité à eux-mêmes. Si leurs actions procédaient d’une bonté aussi simple que l’ouverture d’une porte accompagnée d’un « naturellement, entrez », cette simplicité a tout d’une énigme qui invite à de sérieuses et profondes réflexions.

À travers une analyse comparée de la Grèce ancienne, de l’Inde classique et de son terrain privilégié, celui des îles Fidji, l’anthropologue anglais esquisse une généalogie des pratiques d’hospitalité. Il montre en quoi fondées « à l’origine » sur les liens de parenté et leur caractère sacré, elles se sont développées et étendues, par le biais d’une parenté fictive et des rites spécifiques, à tout étranger considéré digne d’entrer dans le cercle familial.
Hospitalité et traditions en Italie du Sud
Authors: Villain-Carapella Florian
Published: June 2019

En Italie du Sud, les traditions familiales qui font obstacle à la modernité économique et technique sont encore vives. Cela a conduit des observateurs tels que Banfield ou Putnam à qualifier le Mezzogiorno respectivement d’« arriéré » ou d’« incivique ». Cependant, le sens remarquable de l’hospitalité dont font preuve les Méridionaux, notamment à l’égard des migrants, n’est-il pas justement l’indice d’une profonde civicness qui leur est refusée ? En sorte que nous demanderons si les sociétés que l’on dit ouvertes n’ont pas quelque chose à apprendre du sud de l’Italie et si cet enseignement ne réside pas dans un lien occulté entre cette disposition à l’hospitalité et la force des traditions dépréciées.
Que perdent nos sociétés quand elles perdent le sens de l’hospitalité ?
Authors: Robertson Fabien
Published: June 2019

Il y a dans les sociétés occidentales actuelles une véritable crise de l’hospitalité que révèle le regard que nous pouvons porter sur les personnes migrantes. C’est que la faible capacité à l’accueil d’une société montre à quel point le monde qu’elle propose cesse d’être hospitalier, et habitable, pour ses propres membres. En effet, à l’instar du don, qui est le « roc de la morale » (Mauss), l’hospitalité peut être le roc de notre être-au-monde.
Pourquoi le « don » de Derrida ne résiste pas à l’épreuve de l’hospitalité
Authors: Stavo-Debauge Joan
Published: June 2019

Cet article met en cause le traitement de l’hospitalité proposé par Jacques Derrida, en revenant sur la conceptualisation du don dessinée dans Donner le temps. Derrida aborde en effet l’hospitalité à partir d’une philosophie du don qui entend disjoindre le « donner » du « recevoir », en s’écartant nettement du modèle du don maussien. L’article montre en quoi la philosophie du don proposée par Derrida s’avère inadéquate pour concevoir l’hospitalité ; d’abord parce que l’hospitalité n’est pas seulement ouverture mais aussi réception, ensuite parce qu’une philosophie de l’hospitalité doit être en mesure de penser la revendication d’hospitalité et les abus d’hospitalité.

L’expérience de l’étrange est une expérience très étrange : il n’y aurait aucun moyen de comprendre l’étrange si nous n’étions pas capables de nous référer à notre propre expérience, mais nous ne pourrions pas non plus comprendre la nôtre si nous n’étions pas capables de faire une expérience de l’étrange.
Introduction of Flexible Manufacturing Systems as a Necessary Measure for the Russian Industrial Development
Authors: Gromova Elizaveta
Published: June 2019

With the onset of the Fourth Industrial Revolution, the business environment becomes inherent in changes that occur with maximum speed, as well as characterized by the systemic nature of the consequences. One of them is the transformation of operational management models in industrial enterprises. The modern manufacturing system should focus not only on speed of response and flexibility, but also on the cost and quality of products. Integration of effective models: agile manufacturing, quick response manufacturing and lean production, in order to extract the best from them is proposed. The purpose of this study is to analyze this flexible manufacturing system and to relate it to the current state of the Russian industrial development. Theoretical and practical aspects of this model are presented. The examples of the flexible models introduction in the Russian industrial sector is allocated. The conclusion about the necessity of the flexible manufacturing systems implementation for the Russian industrial development is drawn.

Preload Effects on Failure Mechanisms of Hybrid Metal-Composite Bolted Joints
Authors: Coman Calin Dumitru , Constantinescu Dan Mihai
Published: June 2019

This paper presents the effects of torque preload on the damage initiation and growth in the CFRP (Carbon Fiber Reinforced Polymer) composite laminated adherent of the single-lap, single-bolt, hybrid metal-composite joints. A detailed 3D finite element model incorporating geometric, material and friction-based contact full nonlinearities is developed to numerically investigate the preload effects on the progressive damage analysis (PDA) of the orthotropic material model. The PDA material model integrates the nonlinear shear response, Hashin-tape failure criteria and strain-based continuum elastic properties degradation laws being developed using the UMAT user subroutine in Nastran commercial software. In order to validate the preload effects on the failure modes of the joints with hexagonal head bolts, experiments were conducted using the SHM (Structural Health Monitoring) technique. The results showed that the adherent torque level is an important parameter in the design process of an adequate bolted joint and its effects on damage initiation and failure modes were quite accurately predicted by the PDA material model, which proved to be computational efficient and can predict failure propagation and damage mechanism in hybrid metal-composite bolted joints.

Researches on the Design and Operation of a Magnetic Drive Micropump for the Mixing of Compatible Fluids
Authors: Ghionea Gabriel Ionuţ , Ghionea Adrian Lucian , Opran Constantin Gheorghe
Published: June 2019

This paper presents the current state of the conception of a magnetic drive micropump, different necessary constructive-technological and functional considerations, 3D modeling using parametric design, main geometric elements of the gears with helical teeth, specific calculations needed to determine the forces loads on the gears and a printed prototype of its model. Researches conducted from an actual micropump version in use led us to the design of an innovative variant, represented by a constructive solution with a driving gear and two driven gears. This ensures the possibility of displacing a fluid mixed of two compatible fluids, but also balancing the loads that appear in the gear mesh during the micropump's operation. This constructive solution is conceived for the size reduction of the pumping installation, for a good homogenization of the two mixed fluids, for an increased reliability of the micropump by reducing wear of moving components in contact, for a reduced noise and vibration.

Published: June 2019

Purpose: We aimed to assess factors associated with therapy failure in patients with community-acquired pneumonia in the intensive care unit (ICU). Methods: Electronic charts of patients with International Classification of Diseases, Ninth Revision, codes of pneumonia who were admitted to the ICU at a tertiary academic medical center in Southern Arizona were reviewed. Results: Antipseudomonal coverage and anti-methicillin-resistant Staphylococcus aureus (MRSA) coverage were often prescribed (58.4% and 54.1%, respectively). Antipseudomonal coverage was rarely necessary as pseudomonal pneumonia was found in only one case (0.9%). Antipseudomonal and anti-MRSA coverage was not associated with improved outcomes. Conclusion: Overprescription of antibiotics in this population remains a significant problem. More work is needed to further limit unnecessary antibiotic use.
Chemical characterization and sources of submicron aerosols in the northeastern Qinghai–Tibet Plateau: insights from high-resolution mass spectrometry
Authors: Zhang Xinghua , Xu Jianzhong , Kang Shichang , Zhang Qi , Sun Junying
Published: June 2019

Abstract. An Aerodyne high-resolution time-of-flight aerosol mass spectrometer
(HR-ToF-AMS) was deployed along with other online instruments to study the
highly time resolved chemistry and sources of submicron aerosols (PM1)
at Waliguan (WLG) Baseline Observatory, a high-altitude (3816 m a.s.l.)
background station located at the northeast edge of the Qinghai–Tibet Plateau
(QTP), during 1–31 July 2017. The average PM1 mass concentration
during this study was 9.1 µg m−3 (ranging from 0.3 to 28.1 µg m−3), which was distinctly higher than those
(2.0–5.7 µg m−3) measured with the Aerodyne AMS at other high-elevation sites
in the southern or central QTP. Sulfate showed a dominant contribution
(38.1 %) to PM1 at WLG followed by organics (34.5 %), ammonium
(15.2 %), nitrate (8.1 %), BC (3.0 %) and chloride (1.1 %).
Accordingly, bulk aerosols appeared to be slightly acidic throughout this
study, mainly related to the enhanced sulfate contribution. All chemical
species peaked at the accumulation mode, indicating the well-mixed and
highly aged aerosol particles at WLG from long-range transport. Positive
matrix factorization (PMF) on the high-resolution organic mass spectra
resolved four distinct organic aerosol (OA) components, including a
traffic-related hydrocarbon-like OA (HOA), a relatively fresh biomass
burning OA (BBOA), an aged biomass burning OA (agBBOA) and a more-oxidized
oxygenated OA (OOA). On average, the two relatively oxidized OAs, OOA and
agBBOA, contributed 34.4 % and 40.4 % of organics, respectively, while
the rest were 18.4 % for BBOA and 6.8 % for HOA. Source analysis for air
masses showed that higher mass concentrations of PM1 and enhanced
contributions of sulfate and biomass-burning-related OA components (agBBOA
+ BBOA) were from the northeast of the WLG with shorter transport distance,
whereas lower PM1 mass concentrations with enhanced OOA contribution
were from the west after long-range transport, suggesting their distinct aerosol
sources and significant impacts of regional transport on aerosol mass
loadings and chemistry at WLG.

Published: June 2019

Abstract. Nitric oxide (NO) measurements from the Solar
Occultation for Ice Experiment (SOFIE) are validated through detailed
uncertainty analysis and comparisons with independent observations. SOFIE
was compared with coincident satellite measurements from the Atmospheric
Chemistry Experiment (ACE) – Fourier Transform Spectrometer (FTS)
instrument and the Michelson Interferometer for Passive Atmospheric
Sounding (MIPAS) instrument. The comparisons indicate mean differences of
less than ∼50 % for altitudes from roughly 50 to 105 km for
SOFIE spacecraft sunrise and 50 to 140 km for SOFIE sunsets. Comparisons of
NO time series show a high degree of correlation between SOFIE and both ACE
and MIPAS for altitudes below ∼130 km, indicating that
measured NO variability in time is robust. SOFIE uncertainties increase
below ∼80 km due to interfering H2O absorption and
signal correction uncertainties, which are larger for spacecraft sunrise
compared to sunset. These errors are sufficiently large in sunrises that
reliable NO measurements are infrequent below ∼80 km.

Abstract. Atmospheric iodine chemistry has a large influence on oxidizing capacity and associated radiative impacts in the troposphere. However, information on the evolution of atmospheric iodine levels is restricted to the Industrial Period while its long-term natural variability remains unknown. The current levels of iodine in the atmosphere are controlled by anthropogenic ozone deposition to the ocean surface. Here, using high-resolution ice core measurements from coastal eastern Greenland (ReCAP ice core), we report the first record of atmospheric iodine variability during the Holocene (last 11,700 years). Surprisingly, our results reveal that the highest iodine concentrations in the record, found during the Holocene Thermal Maximum (~ 11,500-–5,500 years before -present). These high iodine levels could be driven by ocean primary productivity resulting in an Early Holocene “Biological Iodine Explosion”. The iodine trend during this past warm period is a useful observational constraint on projections of future changes in Arctic atmospheric composition and climate resulting from global warming.
Analysis of the effect of fish oil on wind waves and implications for air–water interaction studies
Authors: Benetazzo Alvise , Cavaleri Luigi , Ma Hongyu , Jiang Shumin , Bergamasco Filippo , Jiang Wenzheng , Chen Sheng , Qiao Fangli
Published: June 2019

Abstract. Surfactant layers with viscoelastic properties floating on the
water surface dampen short gravity-capillary waves. Taking advantage of the
known virtue of fish oil to still angry seas, a laboratory study has been
made to analyse wind-wave generation and the interaction between wind
waves, paddle waves, and airflow. This was done in a tank containing a thin
fish-oil film uniformly spread on the water surface. The research was aimed,
on the one hand, at quantifying for the first time the effectiveness of this
surfactant at impeding the generation of wind waves and, on the other, at
using the derived conditions to disentangle relevant mechanisms involved in
the air–sea interaction. In particular, our main interest concerned the
processes acting on the wind stress and on the wave growth. With oil
on the water surface, we have found that in the wind-only condition (no
paddle waves) the wave field does not grow from the rest condition. This
equilibrium is altered by irregular paddle (long) waves, the generation and
evolution of short waves (in clean water and with oil) being modified by
their interaction with the orbital velocity of the long waves and their
effect on the airflow. Paddle waves do grow under the action of wind, the amount being similar in clean and oily water conditions, a fact we ascribe to
the similar distortion of the wind vertical profile in the two cases. We
have also verified that the wind-supported stress on the oily water surface
was able to generate a surface current, whose magnitude turns out to be
comparable to the one in clean water. We stress the benefits of experiments
with surfactants to explore in detail the physics at, and the exchanges
across, the wavy and non-wavy air–water interface.
Stratigraphy and sedimentology of the Orakei maar lake sediment sequence (Auckland Volcanic Field, New Zealand)
Authors: Peti Leonie , Augustinus Paul C.
Published: June 2019

Abstract. Global paleo-climate reconstructions are largely based on observations from
the Northern Hemisphere despite increasing recognition of the importance of
the Southern Hemisphere mid-latitudes for understanding the drivers of the
global climate system. Unfortunately, the required complete and
high-resolution terrestrial records from the Southern Hemisphere
mid-latitudes are few. However, the maar lakes in the Auckland Volcanic Field
(AVF), New Zealand, are crucial in this regard as they form outstanding
depositional basins due to their small surface-to-depth ratio, restricted
catchment, and absence of ice cover
since their formation, hence ensuring continuous sedimentation with anoxic
bottom water. Significantly, the estimated age of the AVF of ca. 250 ka may
allow development of a continuous sediment record spanning the last two
glacial cycles. The Orakei maar lake sediment sequence examined in this study
spans the Last Glacial Cycle (ca. 126 to ca. 9.5 ka cal BP) from the
phreatomagmatic eruption to the crater rim breach due to post-glacial
sea-level rise. Two overlapping cores of >100 m sediment were retrieved
and combined to develop a complete composite stratigraphy that is presently
undergoing a wide range of multi-proxy analyses.

Per pastarąjį dešimtmetį ženkliai išaugo sedacijos ir anestezijos taikymo neoperacinėje aplinkoje poreikis. Šį proveržį lėmė besivystančios diagnostinės ir gydomosios procedūros. Nors šios procedūros dažnai apibūdinamos kaip minimaliai invazinės ir sąlygiškai trumpos, jų metu išlieka didelė galimų komplikacijų tikimybė. Šiame straipsnyje apžvelgsime literatūros duomenis, nagrinėjančius problemas bei iššūkius, su kuriais gali susidurti gydytojas anesteziologas, dirbdamas neoperacinėje aplinkoje, ir aptarsime gaires pacientų saugumui šių procedūrų metu užtikrinti.

Genus Mentha belongs among the important part of spice, aromatic and medical plants. It includes a large amount of varieties and forms which are not spread generally because of low knowledgeability about possibilities of individual varieties using and also about their high content of bioactive substances. Five less-known varieties and forms (Mentha x piperita var. ´Danica´, Mentha x piperita var. ´Chocolate´, Mentha arvensis f. Banana, Mentha sp. f. Mojito, Mentha sp. f. White Grape) with different aroma and plant habitus were chosen to estimate the content of essential oils, chlorophyll a, chlorophyll b and carotenoids. From obtained results varietal variability of individual varieties and forms have been specified and compared with commonly used Mentha x piperita. The content of essential oils was estimated by steam distillation. The pigment content was determined by spectrophotometric measurement of absorbance at a wavelength of 649 nm (chlorophyll a), 665 nm (chlorophyll b) and 450 nm (carotenoids). The results showed that ´Danica´ and ´Chocolate´ varieties have reached the highest amount of essential oils. Most of the chlorophyll a, b and carotenoids content reached commonly used Mentha x piperita, but there wasn´t found significant difference when compared with ´Danica´ and ´Chocolate´. The effect of varietal variability on the content of qualitative characteristics in the case of essential oils, chlorophyll a and b was confirmed according to used statistical analyse (p <0.05). The varietal variability of tested mint forms and varieties on carotenoids content was not confirmed.
Undergraduate Critical-Thinking Development: Permitted, Prompted, or Pushed?
Authors: Halx Mark D. , Reybold L. Earle
Published: June 2019

This qualitative study explores undergraduate critical-thinking development from the perspective of students, faculty, and academic affairs administrators. We interviewed three different student cohorts at the end of both the first and second semesters of their first year at a selective liberal arts university in south/central Texas. We also interviewed all faculty members who taught these students, as well as the entire academic affairs staff that provided oversight during the year of the study. We found three distinct and viable approaches to critical-thinking development, but one stood out from the others as the most reliable means to stimulate early development.
AVALIAÇÃO DA VULNERABILIDADE SOCIOAMBIENTAL À DESERTIFICAÇÃO NO ESTADO DO ESPÍRITO SANTO, BRASIL

O processo de desertificação é caracterizado pela influência do clima, que emregiões secas (áridas e semiáridas) é o fator preponderante de fragilidadedo ambiente, que provoca déficits sociais e econômicos, que por sua vezretroalimentam o processo por meio da pressão da população sobre o meioambiente. O índice de vulnerabilidade socioambiental à desertificação (IVSD)foi desenvolvido em um sistema de informações geográficas utilizando dadosambientais e socioeconômicos, tais como taxa de analfabetismo, crescimentopopulacional, produto interno bruto, rendimento médio da população,precipitação, evapotranspiração, temperatura da superfície, índice de arideze monitoramento da qualidade da água. No desenvolvimento do IVSDfoi realizada uma análise estatística dos dados preparados e calculados.Essa análise consistiu na eliminação dos valores de pico e na divisão de trêsclasses por percentis (classes de vulnerabilidade alta, média e baixa), compercentis de 0 a 33,33%; 33,33 a 66,66%; e 66,66 a 100%, respectivamente.  O objetivo desta pesquisa foi desenvolver e avaliar um índice paradeterminação da vulnerabilidade socioambiental à desertificação no estadodo Espírito Santo, visando identificar as regiões mais vulneráveis a esseprocesso. O IVSD evidenciou uma área localizada no norte-noroeste, que já éconsiderada oficialmente como uma área susceptível à desertificação, e umaárea localizada no extremo sul, que embora possua as mesmas características,não é considerada oficialmente uma área susceptível à desertificação.O IVSD permitiu evidenciar a necessidade de implantação e de melhorias daspolíticas públicas para promover o avanço no desenvolvimento das regiõesmais fragilizadas do Espírito Santo, visando torná-las menos vulneráveis aosprocessos de desertificação.
Talking about the weather: Two construals of precipitation events in English
Authors: Levin Beth , Krejci Bonnie
Published: June 2019

Weather expressions such as It is raining have proven challenging for linguistic researchers; not only do weather expressions often have special linguistic properties, but languages show considerable variation in the morphosyntactic expression of such events. The main claim pursued here is that, in English, precipitation happenings can be linguistically construed as events (in the sense of Levin & Rappaport Hovav 2005) in two ways: as substance emission events—the sky is construed as emitting the precipitation—or as directed motion events—the precipitation is construed as moving down towards the earth due to gravity. Each construal involves a distinct event structure and, thus, is associated with its own pattern of syntactic behavior. When a precipitation happening is construed as a substance emission event, a type of activity, the verb expressing it shows the hallmarks of an unergative. When a precipitation happening or a substance emission happening is construed as a directed motion event, a type of scalar change event, the verb expressing it shows the hallmarks of an unaccusative. This paper focuses on English, but briefly discusses how the proposed analysis of English can illuminate the diverse behavior of weather verbs across languages. The availability of two construals sheds light on the expression of precipitation events in Romance languages, particularly on the continuing controversy about whether weather verbs are unaccusative or unergative.
A Materially Contextualised Account of Waste Pickers’ Marginalisation in Brazil: The Case of ‘Rubbish PET’
Authors: Pereira da Silva Tatianna Mello
Published: June 2019

Based on the acknowledgment of the materiality of recyclable materials, and therefore of their condition of actants in the recycling market, this paper proposes a materially contextualised account of waste pickers’ marginalisation in Brazil, departing from the extant literature on the topic. Drawing on a mixture of interviews and participant observation data collected during six months of fieldwork using the follow-the-thing approach, it explores the case of ‘rubbish PET’, (i.e., PET—polyethylene terephthalate) bottles dyed in colours other than green or blue to which there is currently no recycling market. The afterlife journey of discarded PET bottles provides the background for a discussion around the capacity of pigments to assert themselves, endangering and defying human efforts to transform discarded PET bottles into resources again. Through the reactions they elicit from those aiming to control their disruptiveness, pigments come to encapsulate the interests of powerful actors and are then transformed into tokens that transmit and reaffirm their hegemony throughout the PET recycling chain, therefore becoming implicated in political processes that contribute to waste pickers’ socioeconomic deprivation.
EFL Learners’ Preferences of Corrective Feedback in Speaking Activities
Authors: Gamlo Nada H.
Published: June 2019

This study examines the preferences and perceptions of Saudi EFL learners concerning the use of Corrective Feedback (CF) during speaking activities. The participants consisted of sixty EFL pre-intermediate female learners in their preparatory year at the English Language Institute (ELI) in King Abdulaziz University in Saudi Arabia. The study utilized both quantitative and qualitative approaches, including a questionnaire to establish learners’ CF preferences when it came to the correction of errors during speaking activities, followed by interviews with ten learners to establish additional information on, and the reasons for, these preferences. The findings revealed that the students held a positive attitude to CF during speaking activities, strongly agreeing that their teachers’ CF could improve their speaking skills. The study also found that students preferred CF to be immediate and to be given by their teachers, who they considered the most qualified to provide such feedback. In addition, the majority of respondents favored receiving CF on their oral grammatical errors. This study provides beneficial information concerning students’ preferences towards the use of CF during speaking activities. This has the potential to contribute to EFL classroom practice, enabling teachers to reevaluate their instruction, particularly in relation to speaking skills, in order to improve speaking proficiency. Moreover, these results contribute to the literature focusing on EFL learners’ preferences when it comes to the use of the CF in English speaking classes in Saudi Arabia.
Determinants of Cost Variation in Total Hip and Knee Arthroplasty: Implications for Alternative Payment Models
Authors: Rudy Michael D. , Bentley Jason , Ahuja Neera , Rohatgi Nidhi
Published: June 2019

Background:

Alternative payment models have been proposed to deliver high-quality, cost-effective care. Under these models, payments may be shared between the hospital and the post-acute care services. Post-acute care services may account for one-third of the episode costs for total hip or knee arthroplasty (THA/TKA). Because hospitals or episode initiators bear notable financial risks in these payment models with minimal risk adjustment for complexity, it has been suggested these models may lead to prospective selection of healthier and younger patients. Studies evaluating the effect of patient demographics, medical complexity, and surgical characteristics on the cost of index hospitalization have been limited. We aimed to (1) quantify the impact of patient demographics, medical complexity, and surgical characteristics (type of anesthesia and operating time) on variation in direct cost of index hospitalization and (2) examine the association of these characteristics with discharge with home health services or to rehabilitation facility.

Methods:

Retrospective study of 3,542 patients admitted to our hospital for elective THA/TKA between 2012 and 2017. Multivariable generalized estimating equations were used for analysis.

Results:

Patient demographics and medical complexity accounted for 6.2% (THA) and 5.6% (TKA) of variation in direct cost of index hospitalization. Surgical characteristics accounted for 37.1% (THA) and 35.3% (TKA) of the cost variation. One thousand one hundred eighty-three (53.4%) patients were discharged with home health services, and 1,237 (29.4%) were discharged to rehabilitation facility. Patient demographics and higher medical complexity were markedly associated with discharge with home health services or to rehabilitation facility after THA/TKA.

Discussion:

Patient demographics and medical complexity had minimal impact on variation in direct cost of index hospitalization for elective THA/TKA compared with surgical characteristics but were markedly associated with discharge with home health services or to rehabilitation facility. Having additional risk adjustment in these payment models could mitigate concerns about access to care for higher risk, higher cost patients.

Introduction:

Unfulfilled expectations, assessed postoperatively, have been consistently associated with dissatisfaction after total knee arthroplasty (TKA). However, identifying these expectations preoperatively has been a challenge. We aimed at identifying specific expectations that are most likely to affect postoperative dissatisfaction.

Methods:

We included all patients in our institutional registry with a body mass index of <40 kg/m2 who underwent primary unilateral TKA and had a minimum 2-year follow-up. Preoperatively, patients completed the 19-item Hospital for Special Surgery Expectations Survey, Short Form-12, Knee Injury and Osteoarthritis Outcomes Score and EuroQol 5-D. Two years postoperatively, patients reported their dissatisfaction on five domains. We estimated logistic regression models to identify the expectation items associated with each domain.

Results:

A total of 2,279 TKA patients (mean age: 65.3 ± 9.2 years; mean body mass index: 30.2 ± 5.9 kg/m2) met our inclusion/exclusion criteria. The association between expectations and dissatisfaction was domain specific, that is, subsets of 4 to 5 items were markedly associated with each dissatisfaction domain, and these expectations differed depending on the dissatisfaction domain examined. Of those, expectations predicting dissatisfaction on multiple domains included kneeling ability and leg straightening and participation in recreation and sports.

Discussion:

We identified a subset of expectations most likely to affect dissatisfaction after TKA. Our findings should inform preoperative patient education approaches on those expectations to realistically orient patient expectations and increase satisfaction.

Level of Evidence:
