On a cosine operator function framework of approximation processes in Banach space
Authors: Kivinukk Andi , Saksa Anna , Zeltser Maria
Published: February 2020

We introduce the cosine-type approximation processes in abstract Banach space
setting. The historical roots of these processes go back to W. W. Rogosinski
in 1926. The given new definitions use a cosine operator functions concept.
We proved that in presented setting the cosine-type operators possess the
order of approximation, which coincide with results known in trigonometric
approximation. Moreover, a general method for factorization of certain
linear combinations of cosine operator functions is presented. The given
method allows to find the order of approximation using the higher order
modulus of continuity. Also applications for the different type of
approximations are given.
Characterization of symmetric distributions based on concomitants of ordered variables from FGMs family of bivariate distributions
Authors: Ahmadi Jafar , Fashandi M.
Published: February 2020

Several characterization results of a symmetric distribution based on
concomitants of order statistics as well as k-records from
Farlie-Gumbel-Morgenstern (FGM) family of bivariate distributions are
established. These include characterizations of a symmetric distribution on
the basis of equality in distribution, moments, R?nyi and Tsallis entropies
of concomitants of upper and lower order statistics, also in terms of the
same properties of concomitants of upper and lower k-records.
On a type of spacetimes
Authors: Suh Young , De Uday
Published: February 2020

In the present paper we characterize a type of spacetimes, called almost
pseudo Z-symmetric spacetimes A(PZS)4. At first, we obtain a condition for
an A(PZS)4 spacetime to be a perfect fluid spacetime and Roberson-Walker
spacetime. It is shown that an A(PZS)4 spacetime is a perfect fluid
spacetime if the Z tensor is of Codazzi type. Next we prove that such a
spacetime is the Roberson-Walker spacetime and can be identified with Petrov
types I, D or O[3], provided the associated scalar ? is constant. Then we
investigate A(PZS)4 spacetimes satisfying divC = 0 and state equation is
derived. Also some physical consequences are outlined. Finally, we construct
a metric example of an A(PZS)4 spacetime.
Sequentially right-like properties on Banach spaces
Authors: Alikhani Morteza
Published: February 2020

In this paper, we study first the concept of p-sequentially Right property,
which is p-version of the sequentially Right property. Also, we introduce a
new class of subsets of Banach spaces which is called p-Right* set and
obtain the relationship between p-Right subsets and p-Right* subsets of dual
spaces. Furthermore, for 1 ? p < q ? ?, we introduce the concepts of
properties (SR)p,q and (SR*)p,q in order to find a condition such that every
Dunford-Pettis q-convergent operator is Dunford-Pettis p-convergent.
Finally, we apply these concepts and obtain some characterizations of the
p-Dunford-Pettis relatively compact property of Banach spaces and their dual
spaces.
On C-parallel legendre curves in non-Sasakian contact metric manifolds
Authors: Özgür Cihan
Published: February 2020

In (2n+1)-dimensional non-Sasakian contact metric manifolds, we consider
Legendre curves whose mean curvature vector fields are C-parallel or
C-proper in the tangent or normal bundles. We obtain the curvature
characterizations of these curves. Moreover, we give some examples of these
kinds of curves which satisfy the conditions of our results.
Selection principles and games in bitopological function spaces
Authors: Lyakhovets Daniil , Osipov Alexander
Published: February 2020

For a Tychonoff space X, we denote by (C(X), ?k ?p) the bitopological space
of all real-valued continuous functions on X, where ?k is the compact-open
topology and ?p is the topology of pointwise convergence. In the papers [6,
7, 13] variations of selective separability and tightness in (C(X),?k,?p)
were investigated. In this paper we continue to study the selective
properties and the corresponding topological games in the space (C(X),?k,?p).

OBJECTIVE

To assess whether initiation of insulin glargine (glargine), compared with initiation of NPH or insulin detemir (detemir), was associated with an increased risk of breast cancer in women with diabetes.

RESEARCH DESIGN AND METHODS

This was a retrospective new-user cohort study of female Medicare beneficiaries aged ≥65 years initiating glargine (203,159), detemir (67,012), or NPH (47,388) from September 2006 to September 2015, with follow-up through May 2017. Weighted Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% CIs for incidence of breast cancer according to ever use, cumulative duration of use, cumulative dose of insulin, length of follow-up time, and a combination of dose and length of follow-up time.

RESULTS

Ever use of glargine was not associated with an increased risk of breast cancer compared with NPH (HR 0.97; 95% CI 0.88–1.06) or detemir (HR 0.98; 95% CI 0.92–1.05). No increased risk was seen with glargine use compared with either NPH or detemir by duration of insulin use, length of follow-up, or cumulative dose of insulin. No increased risk of breast cancer was observed in medium- or high-dose glargine users compared with low-dose users.

CONCLUSIONS

Overall, glargine use was not associated with an increased risk of breast cancer compared with NPH or detemir in female Medicare beneficiaries.
Micromachining of the back surface and interior of Si using infrared femtosecond laser pulses
Authors: Luong Khanh Phu , Tanabe-Yamagishi Rie , Yamada Noboru , Ito Yoshiro
Published: February 2020

This paper reports the 3D microprocessing of Si using a femtosecond laser at a wavelength of 1552.5 nm. As Si is optically transparent at this wavelength, the authors attempted to machine the back surface and interior of a Si substrate by a nonlinear absorption process, similar to the nonlinear process used to treat dielectric materials using visible and near-infrared ultrashort lasers. The femtosecond laser impinged on the front surface while focusing at or near the back surface. The authors scanned the laser beam linearly at several focus positions across the back surface at different scan speeds and repetition rates. Changes occurring in the interior of Si were observable only by infrared microscopy, whereas those on the back surface were observable by visible optical microscopy and scanning electron microscopy. Meanwhile, no change was detected on the front surface where the laser impinged. After a certain period, the point of irradiation showed changes; afterward, changes in the interior of Si began to occur continuously. However, the changes on the back surface occurred in a rather discrete manner, observed intermittently. This may be attributed to the heat accumulation due to multiple pulse irradiations, which increased the local temperature. This resulted in increased absorption along the incident laser path and prevented the delivery of a sufficient amount of energy to induce ablation on the back surface. The morphologies observed on the altered back surface were a granular band and a laser-induced periodic surface structure.

Authors: S. Khot Rahul , Venkateswara Rao T. , Keskar Abhishek , Girish H. N. , Madhusudan Puttaswamy
Published: February 2020

In this study, the characterization of laser weld joint on transformation-induced plasticity (TRIP) steel sheets coupled with Nd:YAG laser welding was investigated, and the influence of welding conditions like angle of weld, power of laser, and welding speed on the strength of the joint was measured. The microstructure, tensile behavior, and microhardness of TRIP laser-welded sheets were examined in detail. The power was maintained constant, i.e., 1800 W, and by relatively varying the velocity from 25 to 30 mm/s, the strength of the joint increased drastically to 11%. In contrast, by varying the power, the effect of velocity was reduced; however, the point performance was enormously stable. Finally, the microhardness behavior of the heat-affected zone and fusion zone was investigated and discussed.

Anticonvulsant valproic acid and other short-chain fatty acids as novel anticancer therapeutics: Possibilities and challenges
Authors: Lipska Katarzyna , Gumieniczek Anna , Filip Agata A.
Published: February 2020

Results from numerous pre-clinical studies suggest that a well known anticonvulsant drug valproic acid (VPA) and other short-chain fatty acids (SCFAs) cause significant inhibition of cancer cell proliferation by modulating multiple signaling pathways. First of all, they act as histone deacetylase (HDAC) inhibitors (HDIs), being involved in the epigenetic regulation of gene expression. Afterward, VPA is shown to induce apoptosis and cell differentiation, as well as regulate Notch signaling. Moreover, it up-regulates the expression of certain G protein-coupled receptors (GPCRs), which are involved in various signaling pathways associated with cancer. As a consequence, some pre-clinical and clinical trials were carried out to estimate anticancer effectiveness of VPA, in monotherapy and in new drug combinations, while other SCFAs were tested in pre-clinical studies. The present manuscript summarizes the most important information from the literature about their potent anticancer activities to show some future perspectives related to epigenetic therapy.
Differential effects of acute and chronic treatment with the flavonoid chrysin on anxiety-like behavior and Fos immunoreactivity in the lateral septal nucleus in rats
Authors: Germán-Ponciano León Jesús , Puga-Olguín Abraham , De Jesús Rovirosa-Hernández María , Caba Mario , Meza Enrique , Rodríguez-Landa Juan Francisco
Published: February 2020

The aim of this study was to compare the effects of acute (a single injection) and chronic (21 consecutive days) treatments with chrysin 2, 4, and 8 μmol kg−1 on anxiety-like behavior and Fos immunoreactivity in the lateral septum nucleus (LSN), a structure that is involved in the regulation of anxiety, in male Wistar rats. These effects were compared with the clinically effective anxiolytic diazepam 7 μmol kg−1. The results showed that acute, but not chronic treatment, with 4 μmol kg−1 chrysin exerted anxiolytic- and anti- depressant-like effects with these effects being similar to that of diazepam. Also, none of the above-mentioned treatments did alter Fos immunoreactivity in the LSN, but a tendency towards the reduction of this variable was detected with chrysin 4 μmol kg−1 and diazepam 7 μmol kg−1. Altogether, results suggest that chrysin exerts anxiolytic-like effects, however, it can produce pharmacological tolerance after repeated use, similar to benzodiazepines.

Published: February 2020

Six new N-pyrrolylhydrazide hydrazones were synthesized under micro synthesis conditions, assuring about 59–93 % yield, low harmful emissions and reagent economy. The structures of the new compounds were elucidated by melting points, TLC characteristics, IR, 1H and 13C NMR spectral data followed by MS data. The purity of the obtained compounds was proven by the corresponding elemental analyses. “Lipinski’s rule of five” parameters were applied for preliminary evaluation of the pharmacokinetic properties of the target molecules. The initial in vitro safety screening for cytotoxicity (on HepG2 cells) and hemocompatibility (hemolysis assay) showed good safety of the new compounds, where ethyl 5-(4-bromophenyl)-1-(1-(2-(4-hydroxy-3-methoxybenzylidene)-hydrazineyl)-1-oxo-3-phenylpropan-2-yl)-2-methyl-1H-pyr-role-3-carboxylate (4d) and ethyl 5-(4-bromophenyl)-1-(1-(2-(2-hydroxybenzylidene)hydrazineyl)-1-oxo-3-phenylpropan--2-yl)-2-methyl-1H-pyrrole-3-carboxylate (4a) were the least toxic. The antioxidant activity in terms of radical scavenging activity (DPPH test) and reducing ability (ABTS) was also evaluated. The antioxidant protective potential of the compounds was next determined in different in vitro cellular-based models, revealing compounds 4d and 3 [ethyl 5-(4-bromophenyl)-1-(1-hydrazineyl-1-oxo-3-phenylpropan-2-yl)-2-methyl-1H-pyrrole-3-carboxylate] as the most promising compounds, with 4d having better safety profile.

Authors: Alqaraleh Moath , Kasabri Violet
Published: February 2020

Background and aims: monomethyl branched chain fatty acids (mmBCFA) and phytochemicals including: Hydroxycitric Acid, Chlorogenic Acid and Piperine have been considered as an interesting agent for researches due to their role in diabetes and cancer. The present study examines the antiglycation effect of mmBCFA and phytochemicals and investigate their Synergistic effect on different colorectal cancer cell lines.

Methods: This study was carried out by using murine monocyte-macrophage cell line and Methylglyoxal (MGO) to enhance the glycation process, furthermore to examine the antiproliferative effect of both the mmBCFA and phytochemicals we use Sulforhodamine B (SRB) assay against obesity related-colorectal cancer cell line panel.

Results: Both phytochemicals and mmBCFA have a higher antiglycation effect than Aminoguanidine (AMG) significantly, moreover, all of the phytochemicals and mmBCFA have antiproliferative against SW620, CACO2 and SW480, nevertheless none of these agents was equipotent to Cisplatin, furthermore, the synergetic effect observed only when we co-incubate Piperine with mmBCFA.

Conclusions: phytochemicals such as Hydroxycitric Acid, Chlorogenic Acid and Piperine and mmBCFA could be used as treatment to prevents the accumulation of advanced glycation end-products (AGEs) in diabetes. Furthermore, the co-incubation between these compounds can inhibit cancer growth, as alternative therapeutic strategy against obesity related-colorectal cancer.

Background and aims: Diabetic peripheral neuropathic pain (DPNP) is one of the most common complications of diabetes and is difficult to treat. Existing treatments are often inadequate at controlling pain and limited by side-effects and drug tolerance. This study assessed the efficacy of nortriptyline versus Transcutaneous Electrical Nerve Stimulation (TENS) in patients with DPNP.

Material and method: This is a randomized clinical trial study conducted on 39 patients with DPNP referring to Golestan Hospital in Ahvaz in 2017. Patients were randomly treated with TENS (18 sessions, each session 30 minutes; n=20) or nortriptyline (25 to 75 mg, once daily; n=19) for 6 weeks. Patients were evaluated for side effects and pain relief using visual analog scale (VAS).

Results: There was a significant improvement in pain with both treatments compared with baseline (p˂0.001). The patients in nortriptyline group experienced more pain relief (7.21±1.51 to 0.84±1.34) than the TENS group (7.6±1.47 to 2.75 ±2.43) (P=0.001). The 50% pain relief was observed in 14 patients (73%) in nortriptyline group, 6 patients (30%) in TENS group. Moreover, the side effects were seen in 15% of TENS and 55% of patients in nortriptyline groups (P=0.019).

Conclusion: Both TENS and nortriptyline were effective and safe in the management of DPNP. But nortriptyline showed a better performance on pain relief.
Tortuously Turning Reality into Theatre: The Case of Nicoleta Esinencu
Authors: Popovici Iulia
Published: February 2020

How do the professionals of the theatre of the real deal with the dilemmas raised by the techniques and ethics of representation that lie at the heart of this particular drama genre? There is little in the available scholarship to provide much guidance in this regard. This article addresses the question and the gap encased within it by examining the critical case of Nicoleta Esinencu, one of the most high profile contemporary drama directors of this kind in Eastern and Central Europe. Focused on the work done by Esinencu at the avant-garde Laundry-Theatre in Kishinev, the analysis dwells on the ethics of documentary work and of representing real life people, the information-gathering process, the choice of topics and the societal implications of the performance. Furthermore, the article captures the bespoke interdisciplinarity of ethnographic research and drama studies while unearthing unsuspected tensions between the claims about representing authentic experiences made by the theatre of the real and the actual perceptions of the professionals.
Transforming Narratives: Reaction, Context and the Emerging (IM)-Possibilities of Social Discourse on Art in Cluj-Napoca
Authors: Braniște Miki
Published: February 2020

The aim of this article is to comprehend the register of existence and the developing of social art practices and discourses in Cluj-Napoca, citing the example of the contemporary art space The Paintbrush Factory, established in 2009. Analysing the operation mode/modus operandi of artists, curators, and cultural agents of Cluj-Napoca, I study the creative pattern based on reaction as a response to the undergoing changes within the socio-political environment of the city as well as those on a global scale. The wider expansion of the urban regeneration theory, that attributes an economic growth factor to culture (based on the existence of creative industries), persuades the local authorities to create a new narrative of a Cluj-Napoca based on the image of a creative city. The Paintbrush Factory is precisely the success story – with a grassroots background, and international standing – that Cluj-Napoca Town Hall needed to legitimise its new development project that sought to put the city on Europe’s map. This ambition of the authorities is reflected in the application for the title of European Cultural Capital 2021. The story of the Paintbrush Factory mirrors this precise transformation of the city, which sees the industrial production being replaced by symbolic production. During this process factories are literally replaced by IT firms and adjacent services, while The Paintbrush Factory that had benefited from a long-term rental of a factory space is eventually displaced in this massive gentrification course of the city.
Allowed Revenue of Network System Operators in the Croatian Energy Sector and Interest Rate Changes on the Croatian Capital Market
Authors: Gelo Tomislav , Vrban Željko , Pudić Dalibor
Published: February 2020

The energy sector is characterized by market and monopoly activities. Monopoly activities include network activities, transmission and distribution of electricity, and transport and distribution of natural gas. For this reason, the revenue of the network activities is defined as allowed income, and it is under the control of the national energy regulator. In Croatia, this is the Croatian Energy Regulatory Agency. The allowed revenues of the network system operator in the Croatian energy sector are defined by the methodologies for individual network activities, which are based on the method of eligible costs. Network activities are usually capital-intensive activities. Capital cost is an element of the eligible cost method and is accounted for as a weighted average cost of capital (WACC). WACC affects the allowed revenue of the network system operator and the network tariff. It depends on the interest rates on debt capital, the risk-free rate, the market risk premium and the corporate tax rate. Changing the interest rate on the capital market, which also depends on the credit risk of the country, affects both the change in WACC and the change of tariffs for transport / transmission of energy. Amortization and operating expenses of the network operator, approved by the energy regulator, also have a significant impact on allowed revenues. The impact of the WACC change on the allowed revenue and network tariffs of network system operators has a different impact on the network tariffs, which depends on the structure of the eligible costs of a particular network system operator. Changing WACC affects the changes in tariffs of the network system operator. The aim of the paper is to determine how an interest rate change affects the WACC and how the change in WACC affects the change in the allowed revenue and the network tariff of the gas transport operator and the transmission of electricity in Croatia. The paper will analyse the tariffs of electricity transmission and natural gas transport in Croatia and compare them with those in the European Union.

Authors: Yin Wong Ji , Wei Poh Kok , Shean Wong Poh , Hafidzah Nik , Suryani Sharifah , Ken Cheah Chee , Koi Ng Tiang
Published: February 2020

Background:

Dengue fever classically presents with fever, arthralgia, myalgia, leukopenia, and thrombocytopenia. A classical presentation with a positive serology test is usually enough to make the diagnosis in an endemic area.

Case Presentation:

A 30-year-old man presented with fever, leucopenia, thrombocytopenia, hepatitis, and delirium. Dengue Immunoglobulin M (IgM) serology was positive. Blood culture grew Salmonella typhi, his ferritin was raised, and bone marrow histology showed histiocytes and hemophagocytic activity. A 2-week course of ceftriaxone (60–75 mg/kg/day) and intravenous immunoglobulin (0.4 g/kg once a day) for 3 days resulted in complete resolution of his illness.

Conclusion:

We report a case of typhoid fever with hemophagocytic lymphohistiocytosis mimicking as dengue fever due to cytopenias and hepatitis, and dengue IgM serology was positive. Although rare, a high index of suspicion is required for early diagnosis and treatment.
Design And Implementation Distributed System Using Java-RMI Middleware
Authors: Sallow Amira B.
Published: February 2020

Networks of computers are everywhere. The Internet is one, as are the many networks of which it is composed. Mobile phone networks, corporate networks, factory networks, campus networks, home networks, in-car networks, both separately and in combination, all share the essential characteristics that make them relevant subjects for study under the heading distributed systems. Most organizations use a wide variety of applications for the smooth functioning of their businesses that includes homogenous as well as heterogeneous systems. Heterogeneous systems run on different platforms, use different technologies or sometimes even run on a different network architecture altogether. The essential role of Middleware is to provide a simple environment to manage complex, heterogeneous and distributed infrastructures.

The main goal of this paper is to use Java-RMI middleware to build a distributed system for scheduling the threads. The system comprises two separate programs, a server, and a client. A typical server program creates some remote objects, makes references to these objects accessible, and waits for clients to invoke methods on these objects. A typical client program obtains a remote reference to one or more remote objects on a server and then invokes methods on them.

Ambrose Philips’ "The Distrest Mother": The myth of Andromache in English (Neo)classicism
Authors: Sebastià-Sáez María
Published: February 2020

The focus of this paper is an analysis of the Ambrose Philips (1674- 1749) neoclassical tragedy “The Distrest Mother” (1712). This play is an adaptation of Jean Racine’s (1639-1699) “Andromaque”(1667), which is, in turn, an adaptation of the Euripides’ ancient Greek tragedy “Andromache” (ca. 426 BC). Philips’ tragedy is an example of an early English adaptation from Racine. Philip took Racine’s play and moulded it to appeal to English taste. Therefore, this study shall analyse Philips’ play focusing on his innovations, mainly in comparison with the Racine version, but also with the ancient Greek myth.

The current state of water supply in Ukraine was analyzed and the main problems that arise on the existing water supply systems, related to the lack of efficiency of both water treatment technologies and operation conditions of the water supply system structures, characterized by high energy consumption, excess pressure formation and accident rate increase were studied. It was specified that in agricultural water supply systems additional difficulties can arise due to significant fluctuations of water consumption during the day, therefore, there is a need for the study of the joint work of interacting structures, especially in the towerless schemes. It is shown that to solve the problems of reliable provision of consumers with the required water amounts, water pressures and water quality, is possible taking into account the requirements of economy, reliability and environmental safety, and to identify weaknesses and develop recommendations for ensuring the efficient operation of structures can be fulfilled by mathematical modeling and analysis of various possible variants of system operation. The issue of increasing the efficiency and reliability of agricultural supply systems was considered using the example of the water supply system in Tarasivka village of Kyiv region. The article deals with increasing the efficiency and reliability of agricultural water supply systems. The results of the study of water supply systems operation, based on the utilization of ground water in the village of Tarasivka, Kyiv region are given, which demonstrate that when pumping water from the well directly into the water supply network, excess damage energy for water lift occurs. The reliability of the water supply system, when pumping water from the well, was analyzed and the measures to ensure cost-effective and reliable operation of water supply structures while reducing the specific costs of electricity for supplying water to consumers and improving its quality were proposed.

Relevance of research. The research is aimed at improving the energy efficiency of automated water supply in irrigation systems. The purpose and objectives of research. The purpose of the research is to reduce the specific energy consumption for pumping water by pumping stations (PS) in closed irrigation systems (CIS). The task is to substantiate the efficiency of the method of automated control of water supply to the CIS when regulating the pressure at the outlet of the pumping station, which is set by the sum of hydraulic losses in the network from the pumping station to irrigation equipment (IE), static and free pressure at the dictating hydrant of CIS. The logical-mathematical model and technological conditions of energy-efficient water supply management "when it need" in CIS are given. The technical requirements for pumping units (PU) and auxiliary technological equipment of PS are presented in the application of automated water supply control with the use of frequency converters (FC).Research methods: experimental, mathematical modeling. Substantiation of the feasibility of introduction of automated electric drive with FC, as one of the measures of energy efficiency improvement, was carried out based on the results of energy audits of the PU and the CIS with the use of measuring equipment on the request of inter-district water management administration. The object of the energy audit is the CIS, which has been in operation since 1979. The PS is equipped with four PU with centrifugal section pumps 150-CVE-350-23/3 (D = 350 mm) and drive motors of the brand MAF315SK-4 with a rated power of 132 kW. During the period of operation the reconstruction and restoration of the CIS took place. “Dnepr” sprinkling machines have been replaced by modern low pressure SM and drip irrigation systems. With the replacement of irrigation equipment, asbestos-cement field pipelines with diameters D = 400 mm were replaced too with the plastic ones of D = 200 mm. The configuration, hydraulic characteristics of the CIS and modes of operation of the PU were changed. The efficiency of the pumps 150-CVE-350-23/3 decreased by 10-15% during the long-term operation of the PU. Research results. For energy efficient water supply management, it is proposed to: replace four worn pumps 150-CVE-350-23/3 with three pumps of domestic production ЦН400-105б; implement a system of automated water supply management at the CIS with the use of FC. Conclusions. The effectiveness of the application of a new method of water supply control in the CIS, which provides for automatic control of the pressure at the outlet of the PS, is given by the sum of hydraulic losses in the network from the PS to the IE, static and free pressure at the dictating inlet of the operating IE, using the proven FC. Introduction of automated electric drive with the FC on the PS-4 of the “Repin” CIS enables to reduce the daily power consumption from 12% to 25%.

The Upside of Acknowledging Prejudiced Behavior
Authors: Moss Aaron J , Budd Rachel , Blanchard Annelise , O'Brien Laurie
Published: February 2020

What do people think of those who respond to confrontation by acknowledging personally prejudiced behavior? In six experiments (N = 3,344), people judged a man who made a prejudiced comment and responded to confrontation by acknowledging, denying, or, in some cases, saying nothing about his prejudice. Participants consistently evaluated someone who acknowledged prejudice as warmer, more moral, and ironically, less prejudiced than someone who denied. People also perceived acknowledging as more appropriate and less typical than denying regardless of whether the prejudice was racism or sexism. Moreover, men and women, White, Black, and Asian people alike evaluated acknowledgements more positively than denials. Evidence from multiple experiments suggests that people form more positive impressions of those who acknowledge than deny because acknowledgment signals more of a learning orientation to prejudice and intergroup relations. Although people frequently respond to confrontation by denying prejudiced behavior, there appears to be an upside to acknowledging.
The (Minimal) Persuasive Advantage of Political Video over Text

Published: February 2020

Concerns about video-based political persuasion are prevalent in both popular and academic circles, predicated on the assumption that video is more compelling than text. To date, however, this assumption remains largely untested in the political domain. Here we provide such a test. We begin by drawing a theoretical distinction between two dimensions for which video might be more efficacious than text: (i) one’s belief that a depicted event actually occurred, and (ii) the extent to which one’s attitudes and behavior are changed. We test this model across two high-powered survey experiments varying exposure to politically persuasive messaging (total n = 7609 Americans; 26,584 observations). Respondents were shown a selection of persuasive messages, drawn from a diverse sample of 72 clips. For each message, they were randomly assigned to one of three conditions: a short video, a detailed transcript of the video, or a control condition. Overall, we find that individuals are more likely to believe an event occurred when it is presented in video versus textual form, but the impact on attitudes and behavioral intentions is much smaller. Importantly, for both dimensions, these effects are highly stable across messages and respondent subgroups. Moreover, when it comes to attitudes and engagement, the difference between the video and text conditions is comparable to, if not smaller than, the difference between the text and control conditions. Taken together, these results call into question widely-held assumptions about the unique persuasive power of political video over text.
Why Are Self-Report and Behavioral Measures Weakly Correlated?

Published: February 2020

Accumulating evidence indicates weak correlations between self-report and behavioral measures of the same construct. We suggest these weak correlations result from poor reliability of many behavioral measures and distinct response processes involved in the two measurement types. We also describe how researchers can benefit from appropriate use of these measures

Little is known about how price evaluation processes unfold. In the current study we explored if reaction times (RTs) can be used to study price evaluations. Additionally, we explored to what extent drift diffusion models (DDMs) are suitable to decompose the different aspects that underlay this decision processes. In a behavioral experiment, participants were asked to evaluate prices as fast as possible as ‘cheap’ or ‘expensive’. We expected that the time needed to evaluate prices would vary in accordance with a price manipulation that was used, and that RTs therefore could be interpreted a proxy of decision difficulty. Analysis of the behavioral data provided evidence for this hypothesis: very cheap and very expensive prices were evaluated faster compared to ambiguous prices. Then, drift diffusion models (DDMs) were used to decompose the different aspect of this decision process, with the goal to obtain a more fine-grained understanding of how the effect in RT data emerged. Results showed that the drift rate of the model was modulated by the price manipulation. Whereas there was no significant effect of the price manipulation on the non-decision time and the starting point parameter. We then contrasted the findings of the RT analysis with the results of the DDMs and outlined what the added value of DDMs is within this context.
Reputations in mixed-role markets: a theory and an experimental test
Authors: Kas Judith , Corten Rense , van de Rijt Arnout
Published: February 2020

The traditional understanding of reputation systems is that they secure trust between strangers by publicly calling out cheaters. In modern, online markets, it is increasingly common for providers of a good to also act as consumers, and vice versa. We argue that in such mixed-role markets, reputation systems serve a second important function: They allow providers who lend out their possessions (such as their house, car or tools) to earn reputational credits that can be spent in future exchanges when in their role as consumer, especially when they do not receive a monetary compensation. In an experiment that introduces a new game, “the Lending Game”, we show that, consistent with our argument, information on past lending leads subjects to lend to those who have themselves lent before, increasing overall lending. However, when provision is financially compensated, and thus no longer a generous act, this reputational mechanism ceases to work.
