Meeting, talk and text: policy and politics in practice
Authors: Freeman Richard 
Published: March 2019

Articles in the Research Provocations section do not simply summarise an existing debate, theme or body of scholarship. Instead, they offer fresh perspectives, develop theoretical advancements and highlight emergent research agendas. This section offers the opportunity for authors to launch high-profile critiques, to showcase acute but comprehensive contributions and to initiate challenging dialogues.
In this Research Provocation, Richard Freeman presents an engaging and thoughtprovoking proposition that existing accounts of the policy process have neglected microlevel practices of politics (talk and text), and consequently have have marginalised the micro-sites of policymaking (the gathering, the encounter and the meeting). To make this argument, he brings together literature from the fields of sociology, political theory and public administration, and makes a case for reconsidering what exactly constitutes the practice of policymaking.
Do you agree with Richard’s argument? To what extent does this account reflect your own academic or practitioner experience? Would you like to respond to Richard’s argument in the pages of Policy & Politics? If so, please get in touch with us to discuss it further!

Our prevailing accounts of the policy process are challenged by studies of practice as well as by practitioners themselves. This paper sets out an alternative, grounded in politics and sociology and informed by recent work in related disciplines. Drawing on the foundational work of Arendt and Goffman, it begins in the essential dynamics of the gathering, the encounter and the meeting. It considers the extent to which each is realised in talk, and in the production and reproduction of texts. Policy and politics seek to establish and maintain a ‘definition of the situation’ and what might follow from it: the purpose of the paper is to match theoretical and empirical accounts of this process with the activity and experience of its practitioners.

The kinetics of oxidation of 4-qaranthiol with chlorine dioxide to disulfide in a solution of acetonitrile was studied by electron spin resonance (ESR). This reaction is the initial stage of oxidation of thiol to sulfonic acid. From the EPR spectra of paramagnetic chlorine dioxide in a solution of acetonitrile, the time dependences of its consumption were obtained for various molar ratios of the thiol-oxidant and temperatures (-10, -15, -20 °C). The kinetic and thermodynamic parameters of the first stage of thiol oxidation are determined (reaction rate constants, pre-exponential factor of the Arrhenius equation, activation energy Ea = 79 kJ / mol, enthalpy ΔH = 76.9 ± 2.5 kJ / mol, entropy change ΔS = -1.7 ± 0.9 J / (mol · K)). It is established that the reaction rate is described by a second-order equation for the concentrations of the reagents. The dependence of the conversion of 4-quarantine on the mole ratio of thiol-oxidant is shown by gas-liquid chromatography with mass spectrometric detection. It was found that complete conversion of the starting thiol is achieved with a 1 : 1 reagent ratio. The maximum yield of disulfide is reached at a molar ratio of chlorine dioxide to organic substrate of approximately equal to 0.4 ÷ 0.5.

The results of studying the influence of natural plant growth regulators Verva and Verva-spruce from coniferous wood greenery on the growth and development of Pinus sylvestris L. pine seedlings under the conditions of a forest nursery are presented. A comparative analysis of morphometric indices and accumulation of phytomass in the first two years of growth of pine seedlings grown from seeds treated with coniferous biopreparations of various concentration (experience) and without processing (control) is lead.
Presowing treatment of seeds with Verva and Verva-spruce preparations at concentrations of 0.1 and 0.25 mL/kg by soaking within 6 hours has led to prolonged effect on growth rates of pine seedlings. Experimental seedlings had higher increments of the aerial part compared to the control: the height of the seedling tree of the first year was 40–84% higher, the second year – 29–47%; the diameter increased by 40–43% in one-year seedlings, and by 2–40% in biennial ones. High values of biometric parameters in two-year seedlings in the experimental versions correspond to the requirements for planting material of coniferous plants. The use of preparations Verva and Verva-spruce for seed presowing treatment will shorten the period of seedling cultivation and the cost of planting material.

Published: March 2019

One of the promising directions of birch bark utilization is its extractive treatment with obtaining a number of valuable chemical components among which the most relevant is betulin. As a rule, the methods of betulin esters are multistage and based on classical reactions of betulin acylation; betulin should be preliminarily extracted from birch bark.
The purpose of the present research was synthesis of the betulin diformate and allobetulin formate directly from the birch bark without a separate stage of the betulin preparation. The external layer of the bark of birch, Betula pendula Roth was ground to particle size of 10–20 mm and used as the raw material. The method is based on combined extraction of betulin from outer birch bark and its formylation with formic acid at reflux for 16 hours. During the treatment of birch bark with formic acid, along with betulin extraction into solution, its formylation into betulin diformate and allobetulin formate occurs. The yield of the formation of betulin diformate and allobetulin formate of the mass of acylated upper bark (a.u.b.) was 40 and 10%, respectively. The first fraction of betulin diformate was obtained from the resulted solution by evaporating 3/4 of the solution and poured it in water to form beige precipitate, whereas the second fraction was extracted by treating the resulted birch bark by acetone followed by evaporation. However, the allobetulin formate was formed from the second treatment of resulted birch bark by chloroforrm followed by evaporation. Betulin diformate was found to be the main component of this extraction, and it was recrystallized from ethyl alcohol to afford beige powder, and its melting point is 165 °C. The structures of betulin diformate and allobetulin formate are confirmed by 1H NMR, 13C NMR, and FTIR spectroscopy.

The pine wood degradation under ozonation was studied. It was determined the contents of lignin (LG) and cellulose (CL) in cellulose-containing material (CM) obtained from the ozonized wood. The degree of polymerization (DP) of cellulose from CM was determined. Samples of CM were investigated using IR diffuse reflectance (DRIFT) spectra and XRD analysis. HPLC analysis of water-soluble LG ozonolysis products was conducted.
Ozonation results in 40–42% delignification degree of wood. Aromatics destruction is confirmed by DRIFT spectra. The intensity of stretching band at 1736 cm-1 of unconjugated C=O groups in LG or hemicelluloses markedly increases.
A stoichiometric ratio of absorbed ozone and an amount of destructed guaiacylpropane units as well as a composition of water-soluble products show that ozonolysis is a primary mechanism of aromatics degradation in wood.
The data on XRD analysis, the amounts of removed LG and the change of cellulose DP allow conclusion that the wood ozonation is accompanied by a destruction of hemicelluloses and amorphous cellulose in the wood.
It is shown that the specific ozone uptake £1.5 mmol O3/g matches the domination of the wood delignification with the lowest degradation of cellulose fibers and acceptable efficiency in terms of the ozonation process.

Published: March 2019

Identity of Botrytis Species on Horticultural Crops In West Java, IndonesiaBotrytis species are economically important pathogens with a very broad host range including more than 200 horticultural crops. The identity of these fungus found in Indonesia has not been investigated and need to be reconfirmed due to the species variations of Botrytis found worldwide. The aims of this research were to identify Botrytis species infecting crops in West Java based on its morphology and molecular characteristics, as well as its pathogenicity traits. Based on morphological characters, all 25 isolates found were identified as B. cinerea. ITS-based sequences of the 8 isolates showed 96-100% similarity to reported B. cinerea in GenBank. The phylogenetic analysis confirmed that all collected B. cinerea were grouped in the same cluster with Australia, Netherlands, and other Asian region isolates. Pathogenicity tests using strawberry fruits demonstrated that all isolates were pathogenic as indicated by grey mold symptom development; the isolates from orchid showed the highest virulence. This research is the first report confirming Botrytis cinerea identity based on morphology and molecular methods in Indonesia, and also confirmed B. cinerea as the only species of Botrytis found in West Java.
Does Captive Insurance Improve Firm Value? Evidence from S&P 500 Companies
Authors: Chang Mu-Sheng , Chen Jiun-Lin 
Published: March 2019

Abstract
This study investigates whether the use of captive insurers affects firm value for companies included in the S&P 500. Companies may use a captive insurance subsidiary to retain their risks for a lower cost than they would pay in premiums to a third-party insurer. Although captives are present in more than one-third of all firm-years between 2000 and 2016, this study fails to find evidence that owning a captive increases firm value effectively. Additional analysis reveals that firms that are larger, are listed on the New York Stock Exchange (NYSE), and have smaller proportions of capital expenditures and cash reserves tend to use captives. Overall, the results are inconsistent with previous research indicating that the market reacts positively to captive formation around the formation date. This suggests that incentives other than shareholder value maximization may have encouraged the use of captives during the sample period.

Published: March 2019

Abstract
Production system operators need support for collecting and pre-processing data on production systems consisting of several system components, as foundation for optimization and defect detection. Traditional approaches based on hard-coded programming of such run-time data collection systems take time and effort, and require both domain and technology knowledge. In this article, we introduce the AML-RTDC approach, which combines the strengths of AutomationML (AML) data modeling and model-driven engineering, to reduce the manual effort for realizing the run-time data collection (RTDC) system. We evaluate the feasibility of the AML-RTDC approach with a demonstration case about a lab-sized production system and a use case based on real-world requirements.
Applicability of generalized test tables: a case study using the manufacturing system demonstrator xPPU
Authors: Cha Suhyun , Weigl Alexander , Ulbrich Mattias , Beckert Bernhard , Vogel-Heuser Birgit 
Published: March 2019

Abstract
With recent trends in manufacturing automation, control software in automated production systems becomes more complex and has more variability to keep pace with customer and market requirements. Quality assurance also becomes more and more important to ensure that the systems live up to expectations. However, correctness of automation software is rarely verified using formal techniques in spite of their high coverage. One of the main reasons is the lack of specification languages suitable for this application area that are both comprehensible and sufficiently expressive. Generalized test tables (GTTs), which are a specification language for reactive systems, were presented recently as an accessible representation for application engineers. This formalism achieves both the comprehensibility of concrete test tables and the coverage of formal methods. In our approach, the specification provided by GTTs is used for formal verification, especially model checking. In this paper, we present four new features for GTTs: the progression flag, strong repetition, row grouping, and specification on internal variables. We demonstrate the applicability and evaluate the comprehensibility of GTT-based specification and verification using a range of diverse scenarios from the community demonstrator, the extended Pick & Place Unit.

Published: March 2019

Abstract
Understanding changes in a manufacturing system is of utmost importance to effectively manage its evolution. This article proposes a pattern-based approach for capturing and describing behavioral changes by integrating recent advantages in the fields of system monitoring and model differencing. Observed changes are described as lifted model differences between two model versions. This helps in explaining observable evolution with a change-first approach.
Grime and Spirit: On a Hype!
Authors: Charles Monique 
Published: March 2019

Abstract
Grime is a genre of Black British music originating from London at the turn of the twenty-first century. In this article, I explore responses to moments of Grime music making and engagement in live performance settings. I make connections between Grime, Black music streams (Lena), Black Atlantic (Gilroy) practices, the Black Public Sphere (Baker) AND how engagements at these intersections are connected to spiritual practice in the context of live performance. The power in Grime live performance settings; where the spiritual is found, connects to the sonic characteristics deployed, embodied and emotive responses and cultural practice. Spirituality, through cultural practice, is an Africanised religious/spiritual outlook that remains with the African diaspora over time and space (Mbiti). Smith’s work shows how African derived religious and spiritual practice continues in diasporic religious practice contemporarily. Through live performance (raving/club culture), I explore and theorise how power is a) generated, b) operates, and outline the roles people play in the cultural-spiritual practice. Building on the work of Smith, Kennett, Sylvan, Mbiti and Baker, I introduce theories: 1) Liminal Energy Power Spirals (LEPS) and 2) AmunRave Theory, to show how the spirit enters live performance space.
Dystopia, Feminism and Phallogocentrism in Margaret Atwood’s Oryx and Crake
Authors: Martín Javier 
Published: March 2019

Abstract
Margaret Atwood’s Oryx and Crake (2003) is a very dark dystopian fable which introduces the reader to a post-apocalyptic scenario in which the planet Earth is on the edge of destruction, and human beings have been almost completely eradicated and substituted for a new, genetically-engineered, race. In this article, I am going to analyse the fundamental role phallogocentrism plays in the destruction of humanity and in the creation of a new world order populated by primitive but more ecological creatures.
Encounters with the Other: Transcultural Possibilities in the Wachowskis’ and Tykwer’s Cloud Atlas
Authors: Trinder Stephen 
Published: March 2019

Abstract
The Wachowskis’ and Tykwer’s Cloud Atlas indicates strong potential for an investigation into the advancement of transcultural messages in global cinema because of its conceptual commitment to narrate the story against the backdrop of sexuality, race, gender, and class. By combining critical discourse analysis (Foucault, The Archaeology of Knowledge, Power/Knowledge) with literary criticisms of postcolonial works (Hall, Hardt and Negri) and transcultural concepts of culture (Welsch, The Puzzling Form of Cultures Today; Rings, The Other in Contemporary Migrant Cinema), this paper investigates how far Cloud Atlas promotes transcultural identity constructs. Upon analysis of central themes and prominent characters Cloud Atlas transmits a message that if the aforementioned socio-cultural barriers can be overcome, we can cultivate something akin to a transcultural society. However, linkages to colonial discourse and quintessential cinematic conventions vis-à-vis white individualistic heroism demonstrate that Cloud Atlas’s liberal-humanist worldview is one that can ultimately be branded as compromised by monocultural assumptions of US values and ideals as superior.
Generalizations of Darbo’s fixed point theorem for new condensing operators with application to a functional integral equation
Authors: Rehman Habib ur , Gopal Dhananjay , Kumam Poom 
Published: March 2019

Abstract
In this paper, we provide some generalizations of the Darbo’s fixed point theorem associated with the measure of noncompactness and present some results on the existence of the coupled fixed point theorems for a special class of operators in a Banach space. To acquire this result, we define α- ψ and β- ψ condensing operators and using them we propose new fixed point results. Our results generalize and extend some comparable results from the literature. Additionally, as an application, we apply the obtained fixed point theorems to study the nonlinear functional integral equations.
Two types of separation axioms on supra soft topological spaces
Authors: Al-shami Tareq M. , El-Shafei Mohammed E. 
Published: March 2019

Abstract
In 2011, Shabir and Naz [1] employed the notion of soft sets to introduce the concept of soft topologies; and in 2014, El-Sheikh and Abd El-Latif [2] relaxed the conditions of soft topologies to construct a wider and more general class, namely supra soft topologies. In this disquisition, we continue studying supra soft topologies by presenting two kinds of supra soft separation axioms, namely supra soft Ti
-spaces and supra p-soft Ti
-spaces for i = 0, 1, 2, 3, 4. These two types are formulated with respect to the ordinary points; and the difference between them is attributed to the applied non belong relations in their definitions.We investigate the relationships between them and their parametric supra topologies; and we provide many examples to separately elucidate the relationships among spaces of each type. Then we elaborate that supra p-soft Ti
-spaces are finer than supra soft Ti
-spaces in the case of i = 0, 1, 4; and we demonstrate that supra soft T
3-spaces are finer than supra p-soft T
3-spaces.We point out that supra p-soft Ti
-axioms imply supra p-soft Ti

−1, however, this characterization does not hold for supra soft Ti
-axioms (see, Remark (3.30)). Also, we give a complete description of the concepts of supra p-soft Ti
-spaces (i = 1, 2) and supra p-soft regular spaces. Moreover,we define the finite product of supra soft spaces and manifest that the finite product of supra soft Ti
(supra p-soft Ti
) is supra soft Ti
(supra p-soft Ti
) for i = 0, 1, 2, 3. After investigating some properties of these axioms in relation with some of the supra soft topological notions such as supra soft subspaces and enriched supra soft topologies, we explore the images of these axioms under soft S
*-continuous mappings. Ultimately, we provide an illustrative diagram to show the interrelations between the initiated supra soft spaces.
Dynamic mechanical analysis (DMA) at room temperature of archaeological wood treated with various consolidants

Published: March 2019

Abstract
The viscoelastic properties of wood samples treated with various consolidants [polyethylene glycols (PEGs), lactitol and trehalose, Kauramin, polydimethylsiloxane (PDMS) and trimethoxymethylsilane (MTMS), rosin and polyethylene-L-tartaramide] were evaluated by means of dynamic mechanical analysis (DMA) in order to clarify their effects with regard to the conservation of wood objects. Two softwoods, medium-decayed silver fir (Abies alba) and highly decayed maritime pine (Pinus pinaster), and two differently decayed oak hardwoods (Quercus spp.) were used. In addition, the selected parameters [retention, volume variations and equilibrium moisture content (EMC)] were evaluated to assess the consolidation efficacy. The results showed that in treated wood, both the storage modulus and tanδ depend upon the level of degradation. The impact of the consolidating product was greater in more degraded wood (a higher product amount inside the artefact) compared to well-preserved material, where also wood played a role (also when the products were applied at high concentrations). The values of the different viscoelastic parameters also depend upon the ability of the products to interact with the wood matrix; this characteristic is fundamental to the nature of each consolidant. Lactitol-treated samples showed the highest stiffness increases, whereas those treated with selected PEG combinations and rosin displayed noticeable tanδ increases (high dissipative behaviour).
Sequence Component-Based Improved Passive Islanding Detection Method for Distribution System with Distributed Generations
Authors: Anudeep Bhatraj , Nayak Paresh Kumar 
Published: March 2019

Abstract
In distributed generation (DG) systems, the rate of change of voltage and the rate of change of frequency are the two most common and widely used simple and low-cost passive islanding detection schemes. Unfortunately, these passive islanding detection schemes find limitation for detecting the islandings that cause very small power imbalance. In this paper, an improved passive islanding detection scheme is proposed by using the two newly derived indices from the sequence components of the current signal with the conventional voltage and frequency parameters. The performance of the proposed scheme is tested for numerous islanding and non-islanding cases generated on IEEE Std 399–1997 and IEC microgrid model distribution system integrated with both inverter-interfaced and synchronous DGs through PSCAD/EMTDC. The obtained results confirm the effectiveness of the proposed scheme.
