Interfacial Heterogeneity is Essential to Water Extraction into Organic Solvents
Authors: Servis Michael , Clark Aurora
Published: September 2018

Liquid/liquid extraction (LLE) is one of the most industrially relevant separations methods, successfully leveraging the variable solubility of solutes (or their complexes) between two immiscible solvents. Independently from the relative solubilities of those solutes and complexes which determine their distribution between phases, the kinetics of phase transfer is impacted by the molecular interactions and structure of those species at the interface. A simple example includes the formation and extraction of water-extractant adducts observed in the ternary water/organic/tri-n-butyl phosphate (TBP) system. Despite its implications for LLE, a detailed description of the structural and dynamic mechanisms by which such adducts are formed at the interface is not established. Describing that process requires connecting the evolving interfacial molecular organization in the presence of surfactants to dynamic surface fluctuations and interfacial heterogeneity. Herein, molecular dynamics simulation is combined with state of the art network theory analysis to reveal features of interfacial structure and their relationship to the extraction of water in the water/n-hexane/TBP system. Surfactant adsorption enhances interfacial roughness which in turn causes directly interfacial water to become less connected through hydrogen bonding to subjacent layers, particularly upon formation of the water bridged TBP dimer adduct. Further, heterogeneity within the interface itself is enhanced by surfactant adsorption, and serves as the basis for the formation of protrusions of water into the organic phase at the extremes of surface fluctuations. These features disproportionately incorporate the water bridged TBP dimer and are the primary means by which water is transferred to the organic phase. This work presents for the first time a holistic understanding of how interfacial heterogeneity and spatial fluctuations become amplified in the presence of surfactants, enabling water extraction into the organic phase. It further affords the opportunity to study how solution conditions can control interfacial behavior to create more efficient solvent extraction systems.

Lateral Response of a Single Pile under Combined Axial and Lateral Cyclic Loading in Sandy Soil
Authors: Kahribt Muqdad Abdallah , Abbas Jasim M.
Published: September 2018

According to practical situation, there have been limited investigations on the response of piles subjected to combined loadings especially when subjected to cyclic lateral loads. Those few studies led to contradictory results with regard to the effects of vertical loads on the lateral response of piles. Therefore, a series of experimental investigation into piles in dense sand subjected to combination of static vertical and cyclic lateral loading were conducted with instrumented model piles. The effect of the slenderness ratio (L/D) was also considered in this study (i.e. L/D= 25 and 40). In addition, a variety of two-way cyclic lateral loading conditions were applied to model piles using a mechanical loading system. One hundred cycles were used in each test to represent environmental loading such as offshore structures. It was found that under combined vertical and cyclic lateral loads the lateral displacement of piles decreased with an increase in vertical load whereas it causes large vertical displacements at all slenderness ratios. In addition, for all loading conditions the lateral, vertical (settlement and upward) displacements and bending moments increased as either the magnitude of cyclic load or the number of cycles increases.

HOW KINDERGARTEN PUPILS SAY “THANKS”: SOCIOLINGUISTIC ANALYSIS IN LANGUAGE TEACHING
Authors: Budiarti Yuniah
Published: September 2018

The study used qualitative design, focusing on how pupils of kindergarten express thank. The subjects of this study were 32 pupils in AL IHSAN Kindergarten Tenggarong and data were collected using observation, interview, and questionnaire. Data for this study were an expression of gratitude delivered using the word “thank” identified from three stimulations. Data were analyzed qualitatively focusing on inferences of context when the word “thank” was uttered and results of interview and questionnaire were clarified. This study discovered that the way pupils of kindergarten on Al Ihsan school communicate to express gratitude vary from explicit manner or smile.  The word “thank” may be changed into “terima kasih” in Indonesian version and “jazakumullah” in Arabic. Not all pupils use the word “thank” however.  Factors that influence the pupils to say “thank” include affective factors, internal and external. Internal factors are a feeling of embarrassment and mood at that time. External factors are the condition and the situation when they receive the gifts and the way how people gave them the gifts. The pupils’ parents background didn’t give an impact by automatically to the pupils by using the expression thank.

Published: September 2018

The paper reports the consideration of technolo-gical vibrating machine dynamic properties on the ba-sis of the model as a mechanical oscillating system with two degrees of freedom having in its structure a device for motion conversion (DMC) forming addi-tional inertial couplings at the simultaneous action of two external harmonic factors. The purpose of investi-gations consists in the development of the method for the formation of simulators ensuring possibilities for dynamic states assessments at the use of such parame-ters of a state as a relation of ties dynamic reactions between a supporting surface (source of kinematic dis-turbance) and a work apparatus.

For investigations there is used a method of structural mathematical modeling within the limits of which the mechanical oscillating system is compared with a structural circuit equivalent dynamically a sys-tem of automatic control. There is offered a technology of starting simulators transformation ensuring a defini-tion of tie dynamic reactions in characteristic points of element contact connection of the system at the simul-taneous action of two factors. It is shown that the joint action of two external disturbances does not change frequencies of characteristic oscillations in the system, but affects considerably its dynamic properties. There are shown diagrams of the dependences of motion points and values of tie dynamic reactions in characteristic points upon a frequency of external im-pact. The manifestations of new dynamic effects in the interactions of system elements between each other as a formation of additional modes of oscillation dynamic damping and amplitude-frequency characteristics (AFC) of a certain type are shown. Dynamic effects predetermine potentialities of a purposeful tuning of vibration fields. It is shown that the value of the shown DMC mass of affect substantially dynamic properties of the system that can be used both for motion parame-ter control, and for the assessment of tie dynamic reac-tions arising at that in the system.

A White Paper on Controlled Digital Lending of Library Books
Authors: Hansen David R. , Courtney Kyle K.
Published: September 2018

This paper is about how libraries can legally lend digital copies of books. It explains the legal and policy rationales for the process— “controlled digital lending”— as well as a variety of risk factors and practical considerations that can guide libraries seeking to implement such lending. We write this paper in support of the Position Statement on Controlled Digital Lending, a document endorsed by many libraries, librarians, and legal experts. Our goal is to help libraries and their lawyers become more comfortable with the concept by more fully explaining the legal rationale for controlled digital lending, as well as situations in which this rationale is the strongest.
Coastal morphology explains global blue carbon distributions
Authors: Twilley Robert R , Rovai André S , Riul Pablo
Published: September 2018

Because mangroves store greater amounts of carbon (C) per area than any other terrestrial ecosystem, conservation of mangrove forests on a global scale represents a potentially meaningful strategy for mitigating atmospheric greenhouse‐gas (GHG) emissions. However, analyses of how coastal ecosystems influence the global C cycle also require the mapping of ecosystem area across the Earth's surface to estimate C storage and flux (movement) in order to compare how different ecosystem types may mitigate GHG enrichment in the atmosphere. In this paper, we propose a new framework based on diverse coastal morphology (that is, different coastal environmental settings resulting from how rivers, tides, waves, and climate have shaped coastal landforms) to explain global variations in mangrove C storage, using soil organic carbon (SOC) as a model to more accurately determine mangrove contributions to global C dynamics. We present, to the best of our knowledge, the first global mangrove area estimate occupying distinct coastal environmental settings, comparing the role of terrigenous and carbonate settings as global “blue carbon” hotspots. C storage in deltaic settings has been overestimated, while SOC stocks in carbonate settings have been underestimated by up to 50%. We encourage the scientific community, which has largely focused on blue carbon estimates, to incorporate coastal environmental settings into their evaluations of C stocks, to obtain more robust estimates of global C stocks.
Visual asymmetries during face encoding Increased dwell time and fixations in the upper and left hemifields
Authors: Felisberti Fatima Maria
Published: September 2018

Visual field asymmetries (VFA) in the encoding of groups rather than individual faces has been rarely investigated. Here, eye movements (dwell time (DT) and fixations (Fix)) were recorded during the encoding of three groups of four faces tagged with cheating, cooperative, or neutral behaviours. Faces in each of the three groups were placed in the upper left (UL), upper right (UR), lower left (LL), or lower right (LR) quadrants. Face recognition was equally high in the three groups. In contrast, the proportion of DT and Fix were higher for faces in the left than the right hemifield and in the upper rather than the lower hemifield. The overall time spent looking at the UL was higher than in the other quadrants. The findings are relevant to the understanding of VFA in face processing, especially groups of faces, and might be linked to environmental cues and/or reading habits.
Agenda Setting and Intra-Party Deliberation: Who gets represented at party national meetings?
Authors: Greene Zac , Sajuria Javier
Published: September 2018

National party meetings provide members with opportunities to express distinct preferences and issue priorities that guide the party’s future policies. Although scholars recognize that party leaders dominate the structure and content of meetings, little empirical research examines the extent of their agenda setting role. Who gets to speak and whose preferences get represented? Adapting theories of legislative agenda setting to the intra-party context, we hypothesize that party candidates are less likely to be chosen as speakers at party conferences when the party’s leadership most demands unity due to their incumbency status. Using self-placements from candidate surveys, we predict the likelihood that MPs and leaders speak at parties’ national meetings in the U.K. We then link candidates’ self-placements to the content of speeches using automated text analysis. These results add to a broad theory of party decision-making which perceives parties’ national meetings as a forum for information sharing, intra-party competition and deliberation. More broadly, evidence in line with this approach suggests that treating parties as unitary actors in a range of settings overlooks important intra-party divisions.

Writing is still considered as a difficult skill in language learning by Indonesian students. For that reason, it is urgent for teacher to seek for interesting ways to teach writing in the classroom. This study examines the effectiveness of  the use of peer feedback technique to improve students’ skill in writing descriptive paragraph. Some studies have proved the effectiveness of the technique to improve students’ writing skill. The study employs experimental research in which one class of 20 students is  taught to write narrative paragraph and correct their paragraph using peer feedback technique. The result of the study shows that the technique improves the students writing skill in narrative writing, however the scores are not significant. This suggests that there is a factor that affects the result of the teaching using peer feedback, and it is the less time of treatment which is indicated as the factor.

Various methods and activities have been undertaken by English teachers to improve the ability of students in English, but the reality shows that a monotonous and tedious method causes students to become passive. This study aims to determine the effect of using the principles of andragogy on the motivation and ability of English speaking students at the Faculty of Law, University of Sawerigading Makassar. The data in this study were obtained through oral tests given in the initial and final tests. The author also uses a questionnaire filled by 25 students from the experimental class. Data obtained from oral tests were then analyzed and interpreted using the SPSS 16 program, while questionnaires were analyzed and interpreted using a Likert scale. The results showed that the treatment given to the experimental class succeeded in improving students' English proficiency. The questionnaire results also show that the average value obtained is 90.16 and can be classified as "very interested". This indicates that the students in the experimental class responded positively to the method used.

Peningkatan Polymorphonuclear (PMN) Dalam Cairan Nasal Lavage Operator Penggilingan Padi Yang Terpajan Endotoksin Lipopolisakarida (LPS)
Authors: Lamawuran William Wilfridus
Published: September 2018

Background: Exposure to lipopolysaccharide endotoxin (LPS) in rice dust causes respiratory inflammation which is characterized by an increase in Neutrophils or Polymorphonuclear (PMN) in the nasal lavage fluid of rice milling operators. Objective: The purpose of this study was to analyze the effect of endotoxin LPS on the rice mill operators' PM in the rice level operators. Methods: the design of this study was a longitudinal study. Dust sampling was carried out for 8 hours while nasal lavage samples were carried out before and after work (cross shift). Endotoxin PMN and LPS were analyzed using the ELISA method and LPS Endotoxin was analyzed using LAL. Results: The mean level of LPS endotoxin in rice dust was 56.36 ± 5.83 EU / m3. An increase in post-employment PMN (Pired sample t-test: p = 0.000) in all rice milling operators. LPS endotoxin levels correlated with increased PMN in nasal lavage fluid in rice milling operators (multiple linear regression test: p = 0.000). Conclusion: LPS endotoxin is a factor that influences the increase of PMN levels in nasal lavage fluid which indicates the occurrence of inflammation in rice mill operators. Suggestion: Use a rice milling machine equipped with a dust collector. Health checks are given to the rest of their work. Workers are advised to always use masks while working.
Modisches Handeln als Strategie der Veruneindeutigung? Eine kritische Diskursanalyse über ‚islamische Mode‘
Authors: Amsler Claudia
Published: September 2018

Der Beitrag beschäftigt sich mit dem medialen Sprechen über vestimentäre Praktiken rund um ‚die islamische Mode‘. Mithilfe der Wiener Kritischen Diskursanalyse argumentiere ich dafür, dass eine postkoloniale Perspektive auf das Themenfeld von Mode und Geschlecht unabdingbar ist. So lässt sich durch die Analyse von deutschsprachigen Berichterstattungen, die durch Interviews mit Expertinnen und ethnografischen Beobachtungen flankiert wurden, die Janusköpfigkeit von modischen Handlungen aufzeigen: Einerseits besitzen modische Handlungen das Potenzial, fixierte Bedeutungen von vergeschlechtlichten und religiös konnotierten Kleidungsstücken zu veruneindeutigen, andererseits können sich in modischen Handlungen und im Sprechen über sie koloniale Blick- und Denkregime aktualisieren. Insbesondere das Stereotyp ‚der unterdrückten muslimischen Frau‘ wird immer wieder aufgerufen und dient in den Berichterstattungen dazu, ein ‚Gegenbild‘ zu konstruieren: die schöne, selbstbestimmte, kauffreudige Muslimin. Durch die referentielle Strategie der Synekdoche und Generalisierung wird dieses ‚Gegenbild‘ homogenisiert, exotisiert und gleichzeitig vereinnahmt.
(Un)modelling Gender: Models zwischen Mode und Gesellschaft
Authors: Giannone Antonella
Published: September 2018

Als Technology of Gender im Sinne von Teresa de Lauretis (1988) steht Modeln im Zeichen des kulturell konstruierten und gesellschaftlich ausgetragenen Weiblichen. Gerade im Kontext dieses geschlechtlich so deutlich markierten Handlungsraums werden gegenwärtig Genderstereotype dekonstruiert und Identitäten infrage gestellt. Dieser Beitrag fokussiert aus modetheoretischer Perspektive auf die kulturelle Rolle des Models. Er setzt sich mit der These auseinander, dass es zu einer prägenden „Sozialfigur der Gegenwart“ im Sinne von Stephan Moebius und Markus Schroer (2010) geworden ist. Als solche adressiert das Model durch seine breit aufgefächerte, intertextuelle bzw. intermediale Präsenz grundlegende Fragen bezüglich der gegenwärtigen Relation zwischen Mode und Identitätskonstruktionen.
Gestalt(ung) des Coming-out. Lesbische und schwule Jugendliche und junge Erwachsene in der Ökonomie der Sichtbarkeit
Authors: Brodersen Folke
Published: September 2018

Coming-out stellt insbesondere für lesbische und schwule Jugendliche und junge Erwachsene eine relevante Aushandlung mit Umfeld und Welt dar. Der Beitrag untersucht das Erleben und Gestalten dieser Praxis. Die Sekundäranalyse 19 problemzentrierter Interviews zeigt, dass Coming-out als Problem des Spektakels hervorhebender Dramatisierung und des unausweichlichen Drucks gedeutet wird. Strategien der Heteronormalisierung, der Usurpation und der Aussetzung der Seinsrelation reagieren auf diese Problematisierungen und setzen sie teilweise außer Kraft. Die Fallstricke der Sichtbarkeit als Politikum, Authentizitätsanforderung und unhintergehbare Tatsache verweisen dabei auf eine gesellschaftliche Wandlung – eine Transformation der Ökonomie der Sichtbarkeit. Trotz – oder gerade wegen – der Vielzahl sich outender Stars und Aktivist_innen, Familien- und Freundschaftserzählungen sind nicht Lesbisch- und Schwul-Sein selbstverständlicher geworden, sondern die Praxis des Comingouts. Der Akt der Herstellung von Sichtbarkeit hat eine Eigenständigkeit entwickelt und ist nun selbst Zeichen der Homosexualität.
Gerechtigkeitsvorstellungen im Lebenszusammenhang – eine geschlechtersoziologische Perspektivenerweiterung am Beispiel von Für- und Selbstsorgearrangements prekär Beschäftigter
Authors: Motakef Mona , Bringmann Julia , Wimbauer Christine
Published: September 2018

Fragen der Un-/Gerechtigkeit v. a. in der Erwerbssphäre sind (wieder) auf die politische Agenda gerückt. Ausgehend von der geschlechtersoziologischen Kritik an einem engen Arbeitsbegriff plädieren wir dafür, Gerechtigkeitsvorstellungen im Lebenszusammenhang zu betrachten. Wir fragen, welche Missstände aus einer Perspektive des Lebenszusammenhangs als ungerecht erfahren werden, basierend auf narrativen Interviews mit prekär Beschäftigten, die wir in einem hermeneutischen Auswertungsprozess interpretierten. Wir rekonstruieren, welche Missstände die Befragten als nicht erfüllte Gerechtigkeitsansprüche erheben und welche nur als nicht erfüllte Wünsche, wobei wir Sorgearrangements ins Zentrum stellen. Anhand dreier Fallbeispiele zeigen wir, dass nur Fürsorge normative Kraft entfalten kann, während zur Einforderung angemessener Bedingungen zur Selbstsorge meist normative Rahmen fehlen. Fürsorge ist zudem vergeschlechtlicht und aus dem Anspruch, gute Pflege zu leisten, kann selbstdestruktives Potenzial erwachsen. Gesellschaftspolitisch ist zu fragen, wie normative Rahmen für angemessene Selbstsorge und gerechte Bedingungen für selbstsorgsame Pflege von Anderen etabliert werden können.
Normalisierung versus Normativität? Dem konstitutiven Außen Rechnung tragen
Authors: Braunmühl Caroline
Published: September 2018

Michel Foucaults Unterscheidung zwischen Normativität und Normalisierung im Sinne je unterschiedlicher Machttechniken ist in neuere Gegenwartsdiagnosen eingeflossen. Ziel des Beitrags ist es, diese Unterscheidung als aus intersektionaler Sicht zutiefst problematisch zu erweisen. Dazu nehme ich in methodischer Hinsicht eine von der Arbeit Judith Butlers geprägte Perspektive auf Normativität und die für sie konstitutiven Ausschlüsse ein. Der Fokus meiner Analyse liegt neben der Foucaultschen Begriffsbildung auf deren Weiterentwicklung durch Jürgen Link und insbesondere durch Gundula Ludwig; in Gestalt von Ludwigs Unterscheidung zwischen Heteronormativität und Heteronormalisierung. Zentrales Ergebnis der Analyse ist, dass die letztere Unterscheidung – wie auch die Foucaultsche Unterscheidung zwischen Normativität und Normalisierung – fälschlicherweise impliziert, Normalisierung sei post-normativ. In meiner Diskussion dieses Befundes schlage ich vor, die von Ludwig entwickelte Unterscheidung durch eine Unterscheidung zwischen Heteronormalisierung und Hetero normation zu ersetzen – wobei diese zwei Machttechniken beide als konstitutiv (hetero-)normativ zu verstehen sind.
