Freemium marketing: use of demand-side research in market segmentation strategy

ABSTRACT Freemium business models are widely used, including by major companies such as Spotify, Pandora, SurveyMonkey, Dropbox and by many start-ups. They are very common in industry segments such as mobile gaming, music, personal productivity, and office collaboration. This marketing management research study uses a case study of a freemium product offering from a major global computer firm to examine the demand side of freemium pricing. The consumer user base for this product is approximately 30 million persons worldwide. This study uses a large-scale (over 5,000) survey of these users to examine consumer response and segmentation. It illustrates how market segmentation can be used to select and optimize offerings to generate additional revenue streams. The authors show how a freemium offering may best be implemented for differential market segments.
Multi-Omic Profiling Reveals the Opposing Forces of Excess Dietary Sugar and Fat on Liver Mitochondria Protein Acetylation and Succinylation

Dietary macronutrient composition alters metabolism through several mechanisms, including post-translational modification (PTM) of proteins. To connect diet and molecular changes, here we performed short- and long-term feeding of mice with standard chow diet (SCD) and high-fat diet (HFD), with or without glucose or fructose supplementation, and quantified liver metabolites, 861 proteins, and 1,815 protein level-corrected mitochondrial acetylation and succinylation sites. Nearly half the acylation sites were altered by at least one diet; nutrient-specific changes in protein acylation sometimes encompass entire pathways. Although acetyl-CoA is an intermediate in both sugar and fat metabolism, acetyl-CoA had a dichotomous fate depending on its source; chronic feeding of dietary sugars induced protein hyperacetylation, whereas the same duration of HFD did not. Instead, HFD resulted in citrate accumulation, anaplerotic metabolism of amino acids, and protein hypo-succinylation. Together, our results demonstrate novel connections between dietary macronutrients, protein post-translational modifications, and regulation of fuel selection in liver.

Financial inclusion determinants and impediments in India: insights from the global financial inclusion index

Purpose The purpose of this paper is to understand the determinants of financial inclusion and the determinants of barriers to financial inclusion in India. Also, the purpose is to ascertain the determinants of informal financial activities in India. Design/methodology/approach The data have been collected from the Global Findex Database (Findex) 2017. Various measures of financial inclusion, namely, ownership formal accounts, use of accounts for saving and borrowing, ownership and use of the debit card are used. The independent variables used are: age, income, education and gender. Given the binary nature of dependent variables, this paper uses the Probit model to draw the inferences. Findings The results show that gender, age, education and income have a significant impact on the various measures of financial inclusion. Additionally, these factors have a significant impact on the informal saving and borrowing. Research limitations/implications The given study uses the deferent measures of financial inclusion. An index of financial inclusion created using all the financial inclusion measures would be a better indicator of financial inclusion. Practical implications The results of this study would be useful for policymakers to identify the determinants and barriers of financial inclusion in India. The results show that policymakers should focus on the female population, in particular, and education and income enhancing measures, in general, to make financial inclusion more inclusive. Originality/value The study is the first of its kind to analyze financial inclusion in India using the Findex. Unlike previous studies, variables such as education and income are constructed more pragmatically. In particular, the study tries to understand the socio-economic determinants of financial inclusion measured as ownership of formal accounts, formal saving, formal credit, ownership of debit cards and use of debit cards. The study also analyzes the determinants of barriers to financial inclusion, savings (formal and informal) and borrowing (formal and informal).
New Records and Functional Role of Anchytarsus palpalis Champion, 1897 (Coleoptera: Ptilodactylidae) in Ecuador

AnchytarsusGuérin-Méneville, 1843 (Coleoptera: Ptilodactylidae) is currently represented by five described species and two undescribed species: A. bicolorMelsheimer, 1845 in easternNorthAmerica; A. instriatus Pic, 1931 and A. substriatus Champion, 1897 in Central America; A. folliculipalpus Stribling, 1986, A. sp. A Stribling, 1986, and A. palpalis Champion, 1897 in Central and South America; and A. sp. B Stribling, 1986 in South America only. Anchytarsus palpalis has been recorded from Ecuador only in Pastaza Province (Amazonia), with unknown coordinates (Stribling 1986). Ecuador is recognized worldwide for harboring substantial biological diversity in many organism groups, including insects. However, the study of insects in this Neotropical country is incomplete, especially for aquatic insectswhere there is a need for baseline data for further research in freshwater ecosystems (Rı́os-Touma et al. 2017). Based on a field experiment and sampling along riparian and stream ecosystems in the Andes and Amazonia, we 1) report new records of the geographic distribution of A. palpalis in Ecuador and 2) assess the contribution of this leaf-shredding invertebrate to leaflitter breakdown in headwaters. For the known geographic distribution of A. palpalis, we searched available online biodiversity databases (GBIF, Invertebase, PANGAEA, Sam Noble Museum, iDigBio, stricollections.org) using the terms Anchytarsus palpalis and gathered the geographic coordinates (and elevation, if available) of existing records. For new geographic records, we collected larval specimens during several field sampling events with a kick-net sampler and from litter bags used in an experiment of leaf-litter breakdown (I~niguez-Armijos et al. 2016). Additionally, we examined several larval specimens identified as Anchytarsus sp. previously deposited in the invertebrate collection of the Museo de Colecciones Biológicas at the Universidad Técnica Particular de Loja (MUTPL), and we reviewed their associated voucher information for ecological and geographical data. For identification of these larval specimens, we used taxonomic identification keys for larvae of the genus Anchytarsus (Stribling 1986). Finally, using both the existing and new records, we created a map of geographic distribution using ArcGIS. Stribling (1986) anticipated that A. palpalis would likely extend throughout the Neotropics. However, after a careful search of online sources, we found that distributional data of this species are scarce. Geographic coordinates (and elevation data)
Revisiting the African supermarket revolution: The case of Windhoek, Namibia

ABSTRACT Africa is rapidly urbanising and urban food systems are being transformed. Some have argued that this transformation is driven by a supermarket revolution akin to that in North America, Europe and Latin America. Others suggest that the supermarket revolution model oversimplifies complex African realities and that urban food systems are experiencing uneven supermarket penetration in the face of resilient informal food sectors. This paper focuses on Windhoek, Namibia, showing that the city’s food system is dominated by South African and local supermarket chains. Since the end of apartheid, South African supermarket chains have expanded their operations into Namibia. Supermarket domination of Windhoek’s urban food system is a function of proximity of South Africa and integration into South African supply chains. In other African countries, supermarket penetration has been much slower and is even being reversed. Explanations for uneven penetration in different countries require greater contextualisation and more case study research.
Diurnal changes of cyanobacteria blooms in Taihu Lake as derived from GOCI observations

Using frequent and long‐term measurements (eight times per day, 2011 to present) from a geostationary satellite sensor (Geostationary Ocean Color Imager, GOCI), this study investigates diurnal changes of cyanobacterium Microcystis aeruginosa blooms (near‐surface high concentrations or surface scums) in Taihu Lake, from which vertical migration patterns could be inferred. After proper atmospheric correction, a cyanobacterial index algorithm is used to quantify equivalent surface cyanobacterial density (σ, 0–100%) at both pixel and synoptic scales from each cloud‐free image, followed by analysis of diurnal changing patterns of σ at both scales. Three typical diurnal changing patterns are identified from all images, which show distinctive and different seasonality from the long‐term statistics. Spatial distributions of the “hotspot” regions where diurnal changes are most often observed have also been established. While the seasonality of the three patterns appears to be a result of seasonality in both temperature and light availability, large blooms only occur 1 d after major wind events. Based on several lines of evidence, we hypothesize that the diurnal changes of such observed surface bloom patterns are likely a result of vertical migration rather than horizontal dissipation/aggregation of cyanobacteria. The mean migration speeds inferred from either a simple model or a radiative transfer model (< 0.03 cm s−1 or < 1 m h−1) are consistent with those reported earlier from laboratory measurements for certain cyanobacteria colony sizes. Complete understanding of the three types of diurnal patterns and direct validation of the hypothesis, however, require further investigations from field measurements.

Application of Electronic Module Teaching Materials to Improve Student Learning Outcomes in Rhythmic Gymnastics Subject

The learning process that is currently taking place in the rhythmic gymnastics course in the Health and Recreation Physical Education study program at the University of Nahdlatul Ulama Lampung is still using the printed module. This is still considered ineffective and inefficient, which causes student learning outcomes in low rhythm gymnastics courses. This study aims to determine the increase in student learning outcomes between before and after being given an electronic module in rhythmic gymnastics courses. The method used in this study was one group pre-test post-test design. In this study, a pre-test and post-test were conducted to determine the increase in student learning outcomes. The increase in student learning outcomes is expressed by the N-Gain score. The results showed that the applied electronic module teaching materials could improve student learning outcomes in rhythmic gymnastics courses. Where the average N-Gain score was 56.75% with the category quite effective. Thus the application of electronic module teaching materials can improve student learning outcomes in rhythmic gymnastics courses.
Organizational Structure, Public-Private Relationships, and Operational Performance of Large-Scale Stadiums: Evidence from Local Governments in China

The financial sustainability of large-scale sport stadiums has become a challenging issue for sport organizations in China due to increasing market competition, lack of professional sport franchises to tenant the facilities, and gradual slow-down in Chinese GDP growth. Previous findings about operational performance of sport organizations identify organizational structure and public-private partnership (PPP) as important predictors. The aim of the current study was (a) to propose a predictive model for operational performance of large-scale stadiums in China and (b) to examine the relationships among organizational structure, PPP, and operational performance. We conducted a literature review to establish a theoretical framework for the proposed model, selected Yangzhou Sports Park and Xuzhou Olympic Sports Center to examine the relationships, and conducted expert interviews to examine the research questions. We found that Xuzhou’s operational performance was more effective due to several mechanisms related to both organizational structure and PPP: incentive, supervision, and assessment. Notably, using built-in benchmark monitoring procedures, Xuzhou managers identified a variety of constraints early on to address onsite problems while maintaining efficient communication among key PPP stakeholders.
Dynamics of biochemical parameters in lambs during the first four months of life

ABSTRACT We aimed to verify whether age influences the biochemical profile of healthy lambs during the first four months of life by characterizing the dynamics of its parameters and verifying whether there are differences between the profiles of growing animals and the reference values established for adults. Blood samples of 34 ½ White Dorper × ½ Suffolk female lambs were collected at 30, 60, 90, and 120 days of age, and the serum concentrations of total proteins, total globulins, albumin, [. ]
Thunderstorm Climatologies and Their Relationships to Total and Extreme Precipitation in China

This study investigates climatologies of lightning and thunderstorms in China and their relationships to total rainfall and extreme (hourly) precipitation (95th percentile) using spaceborne lightning, microwave, and radar measurements. Annually, total and extreme precipitation only weakly collocate or correlate with flash density (FLD) and thunderstorm. Also, none of these variables show significant trends during 1995–2014. FLD and precipitation are generally in phase on the monthly time scale, except over southern China (SCH), where FLD leads precipitation by 2 months. Thunderstorms contribute 40–50% of total rainfall and 70–80% of extreme precipitation over lower‐elevation regions, but only 20% over the Tibetan Plateau. While correlation coefficients between extreme precipitation and flash rate are decent during April–May (AM, r = 0.75), they are significantly lower in June–July–August (JJA, r = 0.55), possibly due to larger warm cloud depth and thus greater rainfall contribution by warm‐rain process during JJA. JJA thunderstorms have markedly higher radar echo tops (MAXHT30) and induce stronger microwave ice scattering than AM thunderstorms, related to larger convective available potential energy in JJA, whereas AM thunderstorms have larger precipitation area in association with stronger vertical wind shear. Conversely, AM thunderstorms show markedly greater number/frequency of high flash rates than JJA thunderstorms (especially over SCH), consistent with their larger volumes of intense radar echo in the mixed‐phase region (VOL35). Compared to MAXHT30 (r = 0.38), VOL35 is far better correlated to flash rate (r = 0.88), as VOL35 represents the total amount of precipitation‐sized ice particles and/or supercooled liquid water in the mixed‐phase region essential for cloud electrification.
Bird community structure in native forest fragments and Acacia mangium plantations in Borneo

ABSTRACT In Southeast Asia, some plantation developers have retained patches of native forest within plantations to promote wildlife diversity, but relatively few studies have examined the effectiveness of such efforts. To provide more information on the interaction between native forest and plantation, we conducted surveys of birds in patches of logged native forest and surrounding groves of exotic plantations in Borneo. We asked the following questions: Does plantation age influence the bird community in adjacent native forest fragments? Are bird communities in the plantations influenced by the presence of small fragments of native forest? Are bird communities in more intensively managed plantations different compared to less intensively managed plantation? Do bird distributions across habitat types vary by functional trait? Our study was conducted in a 500,000 ha multi-use landscape in Sarawak, Malaysia. We identified 15 native forest fragments within exotic plantation, and these were partitioned into old (>7 yr) and young (<5 yr) groves. We conducted surveys in the native forest fragments and in the 2 age groups of adjacent plantation at distances near (<500 m) and far (>500 m) from fragments. Species richness was highest in native forest fragments. In plantation groves near fragments, species richness remained comparable to native forest but dropped significantly in young plantation far from fragments. The International Union for Conservation of Nature (IUCN) threat status was significantly related to species habitat associations, with Near Threatened species preferring native forest. Although protecting large tracts of native forest is optimal for protection of birds, smaller patches may also maintain considerable levels of species richness in plantations, and they may be particularly important during the early phases (first 5 yr) of plantation growth.

 flash specifications for open systems in the absence or presence of chemical reactions

Diverse engineering fields request flash calculations like isothermal flash, isenthalpic flash, and isentropic flash. They can be cast as minimization of a thermodynamic state-function and solved by Michelsen’s Q-function approach. Flash calculations for open systems, i.e. systems where chemical potentials are specified instead of the mole numbers for some components, also belong to this scope. By analyzing the construction of Q-functions through Legendre transforms, we extend this approach to the flash for open systems in the absence or presence of chemical reactions, resulting in general formulations for various specifications. For systems without reactions, the classical framework using mole numbers as independent variables is employed; for those with reactions, the modified-RAND framework is employed. We present examples for open systems at constant temperature and pressure. Using the Q-function minimization, we can solve multicomponent non-reactive or reactive systems at a specified chemical potential with quadratic convergence over a wide range of conditions.
Modeling and stability analysis of dynamic oscillation behaviors in double‐input Buck/Buck‐Boost DC‐DC converters using frequency selective approach

Different from single‐input single‐output converters, stronger nonlinearity and coupling effect become ones of the most salient characteristics in the multiport DC‐DC converters (MPCs). Therefore, the MPCs can exhibit a great variety of more complex oscillation behaviors in different frequency regimes and seriously endanger system stability. In this paper, a frequency‐selective averaging model is proposed to investigate the low‐ and high‐frequency stability problem in the double‐input Buck/Buck‐Boost DC‐DC converter. At first, to characterize both low‐ and high‐frequency regime dynamics in one unified frame, the short‐time Fourier transform will be applied to obtain a frequency‐selective averaging model. Based on the proposed model, theoretical analysis is performed to identify subharmonic oscillation and low‐frequency oscillation by the movement of the eigenvalue loci. In particular, the underlying mechanism of the subharmonic oscillation and low‐frequency oscillation is uncovered deeply by participation analysis. It shows that period‐doubling bifurcation and Hopf bifurcation result in the subharmonic oscillation and low‐frequency oscillation, respectively. Moreover, some stability boundaries show the influence of varying parameters on system stability thoroughly, which is important to guide system stability enhancement. Finally, some circuit experiments are presented to verify the above theoretical and numerical results.
Examining Views of Police Chiefs and College Students Regarding Drug Disqualifiers for the Hiring of Police Officers in Arizona

Police applicant disqualification due to prior illegal drug use is a contributing factor to major recruitment and hiring challenges currently facing many American policing agencies. This article explores how chief executives of law enforcement agencies and college students enrolled in criminology courses in Arizona view current statewide police hiring standards related to prior drug use. We use surveys conducted in cooperation with the Arizona Peace Officer Standards and Training Board to examine respondent opinions regarding the preemployment use of marijuana and illicit use of prescription drugs. Generally, we find significant differences between the chief executive and student views. Students, who represent potential policing applicants, typically are in favor of harsher treatment of prior drug use than chief executives, although students are also more open to forgiving marijuana use under certain circumstances. We discuss the implications of these findings for police hiring and suggest potential areas of policy change.
Les mollusques benthiques du bassin de Marennes-Oléron : estimation et cartographie des stocks non cultivés, compétition spatiale et trophique, dynamique de population de Cerastoderma edule (L.)

L'estimation des stocks des mollusques benthiques du bassin ostreicole de marennes-oleron a ete effectuee par echantillonnage aleatoire stratifie precede d'une allocation optimale de l'effort d'echantillonnage. Apres correction des biais methodologiques, la biomasse totale des stocks malacologiques non cultives est evaluee, au printemps 1984, a 155003000 tonnes. Le niveau de precision obtenue par ce plan s'avere tres similaire a celui calcule par une procedure geostatique. Les suspensivores competiteurs trophiques des huitres crassostrea gigas d'elevage representent pres de 75% de ce stock avec principalement cerastoderma edule (50002400 tonnes), mytilus edulis, crepidula fornicata et solen marginatus. Leur impact en terme de competition trophique vis-a-vis des huitres cultivees semble localement appreciable mais negligeable a l'echelle du bassin. La cartographie des peuplements malacologiques revele que le peuplement a macoma balthica domine sur l'ensemble des estrans avec une preponderance des populations de cerastoderma edule sur les estrans sableux. Un suivi pluriannuel de dynamique de population de c. Edule base sur un echantillonnage aleatoire stratifie a permis de quantifier les phenomenes de recrutement, croissance, mortalite et la relation stock-recrutement en regard de l'impact de la pecherie a pied exercee sur cette espece. Des modeles de croissance saisonniere sont presentes. En complement, la determination de l'evolution saisonniere et pluriannuelle des principaux constituants biochimiques de la chair de c. Edule (protides, lipides et glucides) met en relief les liens etroits entre leurs cycles d'evolution et les phenomenes saisonniers de reproduction, croissance et mortalite naturelle
