How Curation Shapes Demand for Digital Information Goods: Estimating Playlist Elasticities for Music Streaming Services

Users of access-based services for digital information goods such as Spotify and Netflix are confronted with seemingly unlimited choice with thousands of movies and millions of songs. To help users navigate, platform operators offer curated selections. On music streaming services, for example, thousands of playlists, covering different genres, artists, and moods are available. This paper studies how the inclusion of a song on curated playlists affects this song’s demand and how content owners (e.g., artists or labels) can strategically use these lists as a marketing tool. To this end, we collect information about the weekly curation of more than 60,000 playlists from a major streaming service which we relate to weekly streaming data for a sample of 54,000 songs over a period of 3 years, for a total of 7 million observations. Overall, we find a strong positive playlist effect with an elasticity of . 20. Our analysis suggests stronger effects for playlists with more followers, featuring similar content from various artists, and with context-based curation. Furthermore, songs by less established artists and older songs benefit more from playlists. These playlist effects are stronger than the effects of traditional advertising, highlighting the vital role of curation in settings with abundant choice.
Impact of Age on the Willingness to Disclose Personal Data in E-Shopping

E-shopping is an increasingly important way of purchasing among all age groups. However, buying online requires disclosing certain personal data which might be sensitive, especially – to older people. This is linked with their lower confidence in online technologies resulting in some degree of cyber fear. Indirectly, it makes older people rely on legal regulations that are passed to protect privacy online. Both, cyber fear and confidence with regulations are dependent on age, but have opposite impacts on the willingness to disclose personal data online. This makes it difficult to assess how age impacts the willingness to disclose personal data. The study approaches this issue from the standpoint of the social exchange theory. The model includes factors of trust and distrust (paranoia), and two types of social exchange.
Development of a Feedback-Controlled Hand Neuroprosthesis: FES-Supported Mirror Training

Functional Electrical Stimulation (FES) is a widely used technique for physical rehabilitation of patients after stroke or spinal cord injury. Several neuroprostheses have been proposed for restoring or improving grasping function in patients [1]. Most of those systems are open-loop: they apply fixed stimulation patterns with predetermined intensities at discrete time events. Adaption towards the timevariant, individual response and the patient’s intention is missing. We introduce a new feedback-controlled hand neuroprosthesis that enables a real-time adjustment of stimulation parameters and virtual electrode positions depending on the patient’s behavior. In the following, the components of the system are described in detail and its benefits for an enhanced mirror training are outlined.

Evolving Gait Control of Physically Based Simulated Robots

: This paper describes the LegGen System, used to automatically create and control stable gaits for legged robots into a physically based simulation environment. In our approach, the gait is de(cid:2)ned using three different methods: a (cid:2)nite state machine based on robot’s leg joint angles sequences; a locus based gait de(cid:2)ning the endpoint (paw) trajectory and using inverse kinematics to determine joint angles; and through a half ellipse cyclic function used to de(cid:2)ne each endpoint trajectory. The parameters used to control the robot through these methods are optimized using Genetic Algorithms. The model validation was performed by several experiments realized with different con(cid:2)gurations of four and six legged robots, simulated using the ODE physical simulation engine. A comparison between these different robot con(cid:2)gura-tions and control methods was realized, and the best solution was selected in order to help us to build a physical legged robot. The results also showed that it is possible to generate stable gaits using Genetic Algorithms in a ef(cid:2)cient manner, using these three different methods.
Organizing Institutions Organizing Committee

Mainly, Kabyle language verbs can be divided into five different themes on the basis of their morphology: aorist, intensive aorist, negative preterit, preterit and participle (with a simple imperative and intensive). Nevertheless, for certain types of verbs, the change of the value does not systematically introduce a morphological change. The CCeC type (three consonants with an ‘’e’’ before the last one), for example, has the same flexion in aorist and preterit, and the CCV type (two consonants and one vowel) has the same flexion in preterit and negative preterit. The negation of simple aorist produces the intensive aorist theme, etc. In other particular cases, the temporal dimension is not taken into account by the verb. The oppositions of the latter are tense independent, the same verbal form can either occur in the past, the present and the future (aspectual language). The tense is distinguished by the context, mainly adverbs, and in some cases by preverbal modalities. Using NooJ tools, especially syntactic grammars, morphological plans, dictionaries and corpus, we will try to write and formalize certain technical cases that will allow us to avoid ambiguities. The first part is based on distinguishing between aorist and preterit, the second, between negative preterit and positive preterit, whereas the third part compares aorist and negative aorist.

Influences of Patient-Related Factors in Diabetes Management Among Non- Insulin-Treated Type 2 Diabetics

Study was conducted to investigate the influences of patient-related factors in diabetic management among non-insulin-treated type 2 diabetics in Outpatient Department, Hospital Kemaman. Convenience interview has been conducted, followed by further review of outpatient cards. Data collected from 29 subjects was analyzed by using SPSS Version 11. The inclusive criteria were patients diagnosed with diabetes for at least one year and on oral hypoglycemic agent. Patients on insulin treatment were excluded. The efficacy parameter was the fasting blood glucose level. 86.2% of study population were non-smokers. 41.4% consumed alternative medicines concurrently with antidiabetic medications. Majority of the subjects practiced lifestyle modifications, 62.1% in the form of routine exercise and 79.3% dietary modifications. 24.1% and 20.7% received counseling before being put on diabetic medications and on lifestyle modifications respectively. Many diabetics have poor understanding on their medications. Only 27.6% have their fasting blood glucose level ≤ 7mmol/L during the study duration. 72.4% patients claimed to have good compliance to the medications prescribed. Study revealed that patients had better glycaemic control if they had better understanding/knowledge about the medications, had better compliance, practice lifestyle modifications and had been counseled before. Other variables (age, smoking and concurrent use of alternative medicines) failed to demonstrate significant effect on glycaemic control. This study revealed problems such as non-optimal glycaemic control, insufficient patients’ knowledge about the disease and medications, and inadequate compliance in diabetic population. Pharmacists can help the community to manage diabetes better. This information is expected to be useful for pharmacists in improving their roles.
Trans-European networks and unequal accessibility in Europe

Nach dem Vertrag von Maastricht sollen die transeuropäischen Netze durch die Verbesserung der Erreichbarkeit benachteiligter Regionen die wirtschaftliche und soziale Kohäsion in Europa erhöhen. Allerdings rveisen alle Elemente dieses enormen lnvestitionsprogramms darauf hin, daß im Cegensatz zu den Annahmen des Vertrags ihr wesentlicher Zweck in der Schaffung effizienter Verbindungen zwischen den großen Wirtschaftszentren zur Verbesserung der globalen Wettbewerbsfähigkeit Europas Iiegt Es istdaher anzunehmen, daß die transeuropäischen Netze die Erreichbarkeitsunterschiede und damit auch die wirtschaftlichen Diskrepanzen eher noch vergrößern, anstatt sie abzumildern. ln dem folgenden Artikel wird die Hypothese der wachsenden Disparitäten in Europa durch die transeuropäischen Netze mittels theoretischer Überlegungen und durch neue Formen der Analyse der Wirkung der transeuropäischen Netze auf die Raumstruktur und die Verteilung der Erreichbarkeit in Europa erörtert.
Normative Data of Forward Head Posture (FHP) by using Innovative Device DGL-MeTer in among Kopargaon District Population-An Analysis

Background: Forward head posture also known as scholar’s neck, recently considered to be most common musculoskeletal postural imbalance, causing protrusion of head anterior to trunk. It is unclear how age related habitual changes such as FHP have an influence on thoracic kyphosis and lumbar lordosis in normal healthy adults. The aim of this study was to introduce an India’s First innovative instrument DGL MeTer (Darade, Ganvir & Ladhe Founder and Maker of Instrument, Mahajan & Tejas Co founder) and its importance in FHP. Methodology: Total 300 subjects were taken, age 11 years onwards. Subjects were asked to stand erect, then DGL MeTerwas placed on sternal notch and the vertical scale was attached to nose tip by sling over scale and then measurements were taken and recorded. Result: The mean for age group was calculated. (11 20 years (7.9 ± 0.8), 21 30 years (8 ± 1.1), 31 40 years (8.2 ± 1.3), 41 50 years (8.5 ± 1.5), 51 60 years (8.8 ± 1.8), 60years above (9.1 ± 2.1)). The mean shows that, as increasing age there is increase in reading of DGL MeTeri. e. , as age increases the posture altered and leads to increase in forward head posture. Conclusion: It has been concluded that, this study supports the innovative DGL – MeTer instrument as a clinical tool for identification of FHP & it is easy to use and helpful to measure Forward Head Posture (FHP).
Thermally tunable interface modes in corrugated waveguides with liquid crystals

We investigate thermally tunable interface modes based on liquid-crystal-filled corrugated waveguide (CW) systems. The CW systems, consisting of two CWs with different topological properties, can create interface modes with very narrow transmission peaks. Based on the thermal properties of liquid crystals (LCs), the interface modes can be used as tunable narrow band filters and thermal sensors. The simulation results show that the frequencies of the generated interface modes can be tuned by changing the connection phase of these two waveguides. Tunability can be achieved by dynamically shifting the interface mode of a terahertz (THz) spectrum by using the external temperature to change the effective refractive index of nematic LC (E7). The maximum tunable frequency range of interface modes is 0.7965–0.8174 THz (over 20 GHz), the achieved narrowest bandwidth is 0.7 GHz, and the maximum Q-factor can reach 1045. Based on these advantages, the proposed CW systems can also be used for high performance temperature sensing and their maximum sensitivity can reach 0.6967 GHz °C−1.
pH-driven enhancement of anti-tubercular drug loading on iron oxide nanoparticles for drug delivery in macrophages

Nanoparticle deployment in drug delivery is contingent upon controlled drug loading and a desired release profile, with simultaneous biocompatibility and cellular targeting. Iron oxide nanoparticles (IONPs), being biocompatible, are used as drug carriers. However, to prevent aggregation of bare IONPs, they are coated with stabilizing agents. We hypothesize that, zwitterionic drugs like norfloxacin (NOR, a fluoroquinolone) can manifest dual functionality – nanoparticle stabilization and antibiotic activity, eliminating the need of a separate stabilizing agent. Since these drugs have different charges, depending on the surrounding pH, drug loading enhancement could be pH dependent. Hence, upon synthesizing IONPs, they were coated with NOR, either at pH 5 (predominantly as cationic, NOR+) or at pH 10 (predominantly as anionic, NOR−). We observed that, drug loading at pH 5 exceeded that at pH 10 by 4.7–5.7 times. Furthermore, only the former (pH 5 system) exhibited a desirable slower drug release profile, compared to the free drug. NOR-coated IONPs also enable a 22 times higher drug accumulation in macrophages, compared to identical extracellular concentrations of the free drug. Thus, lowering the drug coating pH to 5 imparts multiple benefits – improved IONP stability, enhanced drug coating, higher drug uptake in macrophages at reduced toxicity and slower drug release.
A research into the feasibility of green roof design in Russia: a case study of the Ryazan region

Introduction. The era of high technologies and economy disrupts interaction between man and nature, worsening the state of the environment and living conditions on Earth. In Russia, the construction industry follows a classical development model and applies stereotypical patterns of urban design. Finding problem solving methods means identifcation of problem triggers that help to clearly understand and develop rational problem tackling mechanisms. Green roofs suggest an advanced approach to architecture and urbanization whereby green spaces take the place of new buildings. Supplementary dynamic space is not reduced to its decorative and environmental functions. Materials and methods. We applied such research methods as analysis, the system approach, synthesis, deduction, and comparative analysis. The initial review of the state of aﬀairs in the Ryazan region was performed with regard for the theoretical nature of this study; correlation and regression analysis were employed to assess territories and spaces. Results. The history of green roof systems is analyzed in the article. Systematization of the eﬀective regulatory and technical framework enabled the co-authors to assess the widespread applicability of the green roof technology in Russia. Special attention is paid to the issues that are not covered by eﬀective domestic regulations. The research work has shown that the frst edition of GOST (All-Russian State Standard) 58875 is an attempt to consolidate previously issued manuals and recommendations. There is no information available about the seasonal efciency of green roof solutions in diﬀerent Russian regions. A number of issues remain unresolved. The “green roof” policy has not been developed. Conclusions. Russia is not ready for large-scale construction of green roofs. Further research into green construction should be carried out with regard for unstable climatic conditions in diﬀerent regions of the country to confrm the feasibility of green roofing at the legislative level.
Speech–breathing interactions under physical load

People frequently speak during physical activities, and this physical load has been found to have perceptible effects on the voice. Competition for the lungs is thought to play a key role in explaining why load affects speech, yet few studies have investigated the breath cycle itself. This dissertation aims to explore interactions between speech-breathing parameters and acoustic features of the speech signal during physical activity. To do this, acoustic and respiratory data were recorded from 48 female German speakers exercising at different intensities while performing different speech tasks. The range of data makes possible diverse analyses; some studies were planned pre-experiment but working with the data has prompted reconsideration of the original plan. The main challenge at this stage is combining the possible studies into a coherent whole.
Ultrasensitive fluorescent aptasensor for MUC1 detection based on deoxyribonuclease I-aided target recycling signal amplification

A novel sensing strategy for sensitive detection of mucin 1 protein (MUC1) based on deoxyribonuclease I-aided target recycling signal amplification was proposed. In this paper, in the absence of MUC1, the MUC1 aptamer is absorbed on the surface of graphene oxide (GO) via π-stacking interactions. This results in quenching of the fluorescent label and no fluorescence signal is observed. Upon adding MUC1, the probe sequences could be specifically recognized by MUC1, leading to an increase in the fluorescence intensity. The detection limit is as low as 10 pg mL−1, and a linear range from 50 pg mL−1 to 100 ng mL−1. The assay is specific and sensitive, and successfully applied to the determination of MUC1 in spiked human serum, urine and saliva. Importantly, the proposed aptasensing strategy has great potential in detecting various protein and even cancer cells.
The Critical Period Hypothesis in Second Language Acquisition: A Review of the Literature

Humans’ ability to acquire language is taken to be a preeminent reflection of the phenomenal capacities that their brains are endowed with. Accordingly, it is an axiomatic fact that language is species-specific and mirrors the “human essence” as the following line of thought purports: “when we study human language, we are approaching what some might call “the human essence”, the distinctive qualities of mind that are, so far as we know, unique to man” (Chomsky, as cited in Fromkin. et al, 2003, p. 3). At this juncture, it is worth noting that language acquisition is a coin with two distinct sides viz: First Language Acquisition (FLA) and Second Language Acquisition (SLA) and whose study has been an attention-grabbing destination for researchers from time immemorial.
Characterization of Metabolic Gene Expression in the RAW 264.7 Monocyte Cell Line

Immune cells undergo changes in gene expression and metabolism when activated by a foreign molecule. Although the changes are short-lived in response to an acute infection, they persist in disorders with underlying chronic inflammation. To understand how changes in gene expression relate to changes in metabolism, the expression of metabolic transporter proteins was analyzed in response to chronic inflammation in a mouse monocyte cell line. Specifically, Glucose Transporter-1 (GLUT1), Monocarboxylate Transporter-1 (MCT1), Monocarboxylate Transporter-4 (MCT4), and Glutamate Aspartate Transporter (GLAST) were analyzed, and it was hypothesized that all the transporters would increase in expression in response to a prolonged inflammatory stimulus when compared to control conditions. RAW 264.7 mouse monocytes were treated with lipopolysaccharide (LPS, 1 mg/mL) or a similar volume of phosphate buffered saline (PBS) for 24 hours. The cells were fixed and subjected to immunocytochemical analyses. Relative fluorescence intensity was measured for the different treatment groups and compared statistically. It was determined that expression of GLUT1 and MCT4 increased in response to LPS, as compared to PBS, whereas MCT1 and GLAST decreased in response to LPS, as compared to PBS. Although the hypothesis was not supported, the data do reflect those of a study using human immune cells that were derived from diabetic patients. The data suggest that this cell-based system could represent the conditions of immune cells derived from humans with chronic inflammation and therefore be used for studies and aimed at finding treatments for those conditions.
Changes in the physicochemical and microbiological properties of probiotic-fermented low-fat yoghurt enriched with barley β-glucan during cold storage

This study aimed to investigate the quality attributes of probiotic-fermented low-fat yoghurt enriched with barley β-glucan (BβG) during cold storage (5 °C) for 21 days. Low-fat yoghurt formulation was based on substitution of fat in the skim milk (SM) with BβG (0.75 %, w/v). Four formulations of yoghurt were prepared. The control formulation (without the addition of BβG) was produced from full cream bovine milk and fermented by yoghurt starter (YS). The first treatment (YS) was produced from SM without BβG and fermented by YS. The second treatment was produced from SM with the addition of BβG and fermented by YS (YSBβG). The third treatment was produced from SM without BβG and fermented by Bifidobacterium lactis Bb-12, and Lactobacillus acidophilus LA-5 (PY). The fourth treatment was produced from SM with the addition of 0.75% BβG and fermented by Bifidobacterium lactis, and L. acidophilus (PYBβG). All samples were evaluated for their chemical composition, microbiological properties, the viability of probiotic microorganisms, sensory quality attributes during the storage period. The results indicated that addition of BβG improved the survival of probiotic bacteria and YS culture during storage period wherein the BβG-enriched yoghurt had high viable count. There were no significant differences (p≤0.05) between the treatments in the microbiological quality and chemical composition. On the other hand, the addition of BβG improved the formation of flavor compounds in yoghurt. The substitution of fat with BβG significantly (p≤0.05) enhanced sensory attributes of yoghurt, wherein BβG-enriched samples recorded high score and acceptability. The lactic bacteria count was 9×107 CFU mL–1, and probiotic culture count was higher than 1×106 CFU mL–1, which guarantees their effect and ability to survive in the digestive tract and spread in the intestine. It could be concluded that substitution of fat with BβG is a sufficient delivery truck of probiotic culture and BβG could be used safely in functional dairy products.
