The Distribution of Well-Being and Income within the Household

Several papers in the literature on intra-household allocation have suggested that various household ‘outcomes’, such as demands, saving, child health etc., depend on the distribution of income within the household. Implicit in these analyses is that a higher share of household income for one partner leads to a higher welfare for that person. In this paper we consider the issue of the intra-household distribution of welfare directly using a survey measure of self-perceived economic well-being. As a supplement to this we also present an analysis of responses to this question for singles; this allows us to ‘benchmark’ the responses for married individuals. Our data are drawn form the Danish component of the European Community Household Survey for the year 1994. We have three principal findings. First, we do not find any impact of the incomes of other non-related (‘peer-group’) persons on the financial satisfaction of singles. This is in contrast to other recent findings that suggest that agents consider relative incomes when considering their own satisfaction. Second, we find that husbands and wives often report very different levels of financial satisfaction. Finally, the most important correlate with relative satisfaction within the household is found to be relative income. This is a direct confirmation of the previously implicit findings.

Antioxidant and Antibacterial Activities of Trema cannabina

3 Abstract: Methanol and aqueous extract of leaves of Trema cannabina Linn. were subjected to the potential antioxidant and antibacterial activities. The pharmacological interest of this plant coupled with traditional use (antidiarrhoeal, antiseptic, analgesic etc) prompted to test for antioxidant and antibacterial activities. The antioxidant potential of the methanolic extract was determined on the basis of their scavenging activity of the stable 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical. IC of the methanol extract of T. cannabina was 50 110.25 µg/ml which indicated the strong antioxidant activity of the plant. However the aqueous extract showed mild antioxidant activity. In case of antibacterial activities test, the extract was subjected for its effectiveness against both Gram-positive and Gram-negative bacteria in agar diffusion method. The zones of inhibition produced by the crude methanol and aqueous extract against few sensitive strains were measured and compared with those of standard antibiotic Gentamycin. It is evident that both extracts are active against the bacteria at low concentrations. The obtained results provide a support for the use of this plant in traditional medicine and suggest its further advance investigation.

Refined blow-up results for nonlinear fourth order differential equations

We study a class of nonlinear fourth order differential equations which arise as models of suspension bridges. When it comes to power-like nonlinearities, it is known that solutions may blow up in finite time, if the initial data satisfy some positivity assumption. We extend this result to more general nonlinearities allowing exponential growth and to a wider class of initial data. We also give some hints on how to prevent blow-up.
Bipolar polaron pair recombination in polymer/fullerene solar cells

The unique properties of organic semiconductors make them versatile base materials for many applications ranging from light emitting diodes to transistors. The low spin-orbit coupling typical for carbon-based materials and the resulting long spin lifetimes give rise to a large influence of the electron spin on charge transport which can be exploited in spintronic devices or to improve solar cell efficiencies. Magnetic resonance techniques are particularly helpful to elucidate the microscopic structure of paramagnetic states in semiconductors as well as the transport processes they are involved in. However, in organic devices the nature of the dominant spin-dependent processes is still subject to considerable debate. Using multi-frequency pulsed electrically detected magnetic resonance (pEDMR), we show that the spin-dependent response of P3HT/PCBM solar cells at low temperatures is governed by bipolar polaron pair recombination involving the positive and negative polarons in P3HT and PCBM, respectively, thus excluding a unipolar bipolaron formation as the main contribution to the spin-dependent charge transfer in this temperature regime. Moreover the polaron-polaron coupling strength and the recombination times of polaron pairs with parallel and antiparallel spins are determined. Our results demonstrate that the pEDMR pulse sequences recently developed for inorganic semiconductor devices can very successfully be transferred to the study of spin and charge transport in organic semiconductors, in particular when the different polarons can be distinguished spectrally.
Entanglement risk to western gray whales from commercial fisheries in the Russian Far East

Western gray whales Eschrichtius robustus (WGWs) are endangered, and their range overlaps areas where several important commercial fisheries operate in the Russian Far East (RFE). Throughout their range, gray whales commonly become entangled or entrapped in fishing gear. In the western North Pacific, they have been killed in set nets and seen entangled with ropes and float lines. Signs of fishery interactions on 28 of 150 living whales photographed near Sakhalin Island were reported in a published study. We describe characteristics of RFE fisheries that might entangle WGWs, including fishing effort based on daily catch reports from 2010−2014. We make a preliminary qualitative assessment of entanglement risk, taking into account factors including (1) evidence that the gear type has entangled large whales, (2) fishing effort, and (3) geographic and temporal overlap between WGWs and fishing activity. Fishing for salmonids with pelagic gillnets is no longer allowed in the RFE, and as long as the prohibition is being followed such fishing poses no risk to WGWs. In contrast, the coastal salmon set net fishery poses a high entanglement risk off northeastern Sakhalin and Kamchatka where WGWs feed very close to shore, and that situation should be mitigated. Bottom-set gillnet, demersal longline, snurrevad (also called Danish seine), and trap and pot fisheries overlap substantially with WGW distribution, and bycatch in those fisheries should at least be monitored. More rigorous risk assessment would require additional information on WGW distribution and movements.
VOT-Analysis: The Production of Stops by Agrammatic Palestinians

The aim of this paper is to study the VOT characteristics of Palestinian Broca’s aphasics and to compare them with those of normal speakers. The acoustic analysis has revealed aberrations in the VOTs of plosive sounds in speech of Broca’s aphasics, by exhibiting an overlap between the places of articulation of the stops under examination /t/ and /d/. In contrast, the normal speakers demonstrate full normal VOT distributions for voiced and voiceless stops. Broca’s aphasics were unable to maintain the normal voicing distinction for Arabic stop consonants. In addition, they revealed different patterns of VOT distribution with the tendency towards greater prevoicing for voiced stops.
Using concept mapping to learn about A level physics students’ understandings of particle physics

This article describes a small-scale piece of research using concept mapping to elicit A level students’ understandings of particle physics, which was presented in the Special Session on Physics Education and Outreach at ICNFP 2017. Fifty-nine Year 12 (16and 17-year-old) students from two London schools participated in the research. The exercise took place during school physics lessons. Students were shown how to make a concept map and were provided with topic-specific key words. Their concept maps were analysed by identifying the knowledge propositions the students had represented, and comparing these with propositions developed from the examination specification they were studying. The only correct statement made by most of the students in both schools was that annihilation takes place when matter and antimatter collide, although some students may have been unable to distinguish between annihilation and pair production. A high proportion of students knew of up, down and strange quarks, and that the electron is a lepton. However, some students appeared to have a misconception that everything is made of quarks. Students found it harder to classify tau particles than they did electrons and muons. Where students made incorrect links about muons and tau particles their concept maps suggested that they thought they were mesons or quarks.
Measuring the Effect of the Local Ethnic Composition on Natives' and Immigrants' Geographic Mobility in France. Evidence from Panel Data (1982-1999)

This article provides empirical results on the patterns of native and immigrant geographic mobility in France. Using longitudinal data, we measure mobility from one French municipality (commune) to another over time and estimate the effect of the initial municipality's ethnic composition on the probability of moving out. Relying on a unique methodology, we try to correct for biases related to selection based on geographical and individual unobservables. Our findings tend to discredit the hypothesis of the "white flight" central pattern in residential mobility dynamics in France. Some evidence nevertheless denotes ethnic avoidance mechanisms in natives' relocating. We also find a strong negative and highly robust effect of co-ethnics' presence on immigrant geographic mobility. The final discussion explores some avenues to interpret these findings.
Rapid Disaster Mapping through Data Integration from UAVs and Multi-sensors Mounted on Investigation Platforms of NDMI, Korea

Abstract. As the recent disaster is so difficult to predict when and where it would hit, so it requires paradigm for disaster shifts from response to preparedness. In order to respond this change, NDMI has studied disaster scientific investigation (DSI) technologies for revealing systematically the root cause of disaster and protecting repetitive recurrence. The purpose of this study is to propose a convergence approach between data acquired from different types of sensors on a van-type investigation platform and UAVs of NDMI and assess their applicability for timely natural and man-made disaster mapping and monitoring. In order to evaluate its applicability for rapid disaster mapping, we pre-tested the proposed approach for NDMI site in Ulsan, Korea. For the enhancement of the direct geo-referencing accuracy of UAV imagery captured from on-board camera of DJI and the creation of more accurate map products, camera IOPs refinement and bundle adjustment were also performed with minimal GCPs. Finally, we conducted UAV data registration with LiDAR point clould for disaster mapping applications.
Oscillation Criteria for Delay Neutral Difference Equations with Positive and Negative Coefficients - doi: 10.5269/bspm.v21i1-2.7504

This paper is concerned with a class of neutral type difference equations with positive and negative coefficients of the form \Delta(x_n − r_n x_{n−m)} + p_nx_{n−k} − q_nx_{n−l} = 0, n = 0, 1, 2, . , where m, k and l are nonnegative integers, and {pn} , {qn} as well as {rn} are nonnegative real sequences. Novel oscillation criteria for this equation are derived.
The Curses and the Blesses of E-Cadherin

E-cadherin is an evolutionary conserved molecule expressing from lower level animal to human. The principal role of E-cadherin is to maintain appropriate cell-cell connectivity at adherensjunction. Besides its role as cell-cell connector protein, E-cadherin is integrally involved in intracellular signaling as well as cytoskeletal remodeling. Proper spaciotemporal regulations as well as relevant specialized functions of E-cadherin are important for maintaining normal embryogenesis, cellular morphology and physiological function. However, defects in the expression and function of this gene products could become curses since numerous genetic and developmental studies have identified the critical role of this gene in path physiological conditions of multiple types of cancers leading to fatality. Recent study identified essential role of this gene product in stem cell biology including normal embryogenesis, induced pluripotent stem cell (iPSC) generation and stem cell differentiation. Currently iPSC has become a prime choice as starting material for regenerative medicine to treat many diseases; however the relevant technology has many shortcomings. Our lab and others have been exploiting this protein for successful application in regenerative medicine that made it a blessed molecule. Here, based on the latest available information, we are concisely presenting these agonies and advantages of E-cadherin.
Critical Literacy Practices in the EFL Context and the English Language Proficiency: Further Exploration

This paper reports a follow-up study that explored the relationship between EFL learners’ critical literacy practices and the English language proficiency. It investigated four focal EFL learners’ critical literacy practices in their dialogic interaction and also analyzed 39 students’ views on their critical literacy learning. The four focal students’ discussion on a gender-related local news article was analyzed based on the concept of critical discourse analysis; the students’ views on critical literacy learning were analyzed both qualitatively and quantitatively. The findings showed that despite the difference in their English proficiency, the four focal students all demonstrated critical literacy in varying degrees as shown in its previous study, and that critical consciousness of gender and class are raised through dialogic interaction. This study thus corroborates the previous one that English proficiency does not hinder EFL learner’s critical literacy practices. Besides, this study had an additional finding; that is, English proficiency levels do affect EFL learners’ views on critical literacy learning. Therefore, a critical literacy-based class would be more acceptable to students whose English proficiency is high.
Observations at terrestrial impact structures: Their utility in constraining crater formation

Abstract— Hypervelocity impact involves the near instantaneous transfer of considerable energy from the impactor to a spatially limited near‐surface volume of the target body. Local geology of the target area tends to be of secondary importance, and the net result is that impacts of similar size on a given planetary body produce similar results. This is the essence of the utility of observations at impact craters, particularly terrestrial craters, in constraining impact processes. Unfortunately, there are few well‐documented results from systematic contemporaneous campaigns to characterize specific terrestrial impact structures with the full spectrum of geoscientific tools available at the time. Nevertheless, observations of the terrestrial impact record have contributed substantially to fundamental properties of impact. There is a beginning of convergence and mutual testing of observations at terrestrial impact structures and the results of modeling, in particular from recent hydrocode models. The terrestrial impact record provides few constraints on models of ejecta processes beyond a confirmation of the involvement of the local substrate in ejecta lithologies and shows that Z‐models are, at best, first order approximations. Observational evidence to date suggests that the formation of interior rings is an extension of the structural uplift process that occurs at smaller complex impact structures. There are, however, major observational gaps and cases, e.g., Vredefort, where current observations and hydrocode models are apparently inconsistent. It is, perhaps, time that the impact community as a whole considers documenting the existing observational and modeling knowledge gaps that are required to be filled to make the intellectual breakthroughs equivalent to those of the 1970s and 1980s, which were fueled by observations at terrestrial impact structures. Filling these knowledge gaps would likely be centered on the later stages of formation of complex and ring structures and on ejecta.
Optimizing the wireless power transfer over MIMO Channels

Abstract. In this paper, the optimization of the power transfer over wireless channels having multiple-inputs and multiple-outputs (MIMO) is studied. Therefore, the transmitter, the receiver and the MIMO channel are modeled as multiports. The power transfer efficiency is described by a Rayleigh quotient, which is a function of the channel's scattering parameters and the incident waves from both transmitter and receiver side. This way, the power transfer efficiency can be maximized analytically by solving a generalized eigenvalue problem, which is deduced from the Rayleigh quotient. As a result, the maximum power transfer efficiency achievable over a given MIMO channel is obtained. This maximum can be used as a performance bound in order to benchmark wireless power transfer systems. Furthermore, the optimal operating point which achieves this maximum will be obtained. The optimal operating point will be described by the complex amplitudes of the optimal incident and reflected waves of the MIMO channel. This supports the design of the optimal transmitter and receiver multiports. The proposed method applies for arbitrary MIMO channels, taking transmitter-side and/or receiver-side cross-couplings in both near- and farfield scenarios into consideration. Special cases are briefly discussed in this paper in order to illustrate the method.
Management of Insect Pest by RNAi — A New Tool for Crop Protection

The fast-growing human population requires the development of new agricultural tech‐ nologies to meet consumers ́ demand, while minimizing environmental impacts. Insect pests are one of the main causes for losses in agriculture production, and current control technologies based on pesticide application or the use of transgenic crops expressing Ba‐ cillus thuringiensis toxin proteins are facing efficacy challenges. Novel approaches to con‐ trol pests are urgently necessary. RNA interference (RNAi) is a gene silencing mechanism triggered by providing double-stranded RNA (dsRNA), that when ingested into insects can lead to death or affect the viability of the target pest. Transgenic plants expressing dsRNA version of insect specific target genes are the new generation of resistant plants. However, the RNAi mechanism is not conserved among insect orders, and its elucidation is the key to develop commercial RNAi crops. In this chapter, we review the core RNAi pathway in insects and the dsRNA uptake, amplification, and spread of systemic silenc‐ ing signals in some key insect species. We also highlight some of the experimental steps before developing an insect-pest-resistant “RNAi plant”. Lastly, we review some of the most recent development studies to control agricultural insect pests by RNAi transgenic plants.
Prevalence of Homeless Older Adults and Factors Causing Their Homelessness: A Review

Objectives: To examine the prevalence of homeless older adults and causes of homelessness among the elderly. Methods: Systematic review involving search of Medline, Cochrane Review and GoogleScholar, including homeless, homelessness, elder, elderly, aged and in old age. For prevalence, articles before 2000 were excluded, and samples had to be at least 50 ±5 years of age. Results: Medline search resulted in 511 articles. Studies outside the United States, focusing on disease- or sitespecific populations and/or not specifying subjects by age were excluded, leaving four studies (prevalence) and two (causes). Two additional articles on prevalence were identified through GoogleScholar, and three others (two about prevalence; one about causes) were identified from manually searching bibliographies of identified articles. Discussion: The prevalence of elderly homeless ranges from 8% to 55% (mean, 27%; median, 24%). Most-often cited reasons leading to homelessness were financial/employment problems, lack of social support, and mental health problems.
Irregular Singularity of the Magnetorotational Instability in a Keplerian Disk

The center of a Keplerian disk is an irregular singularity for the eigenfunctions of magnetorotational instabilities. The system is studied using the small-radius approximation, which by no means implies that the analysis is valid only in the vicinity of the center of the astrophysical disks. In fact, the singularity has an effect on the entire disk and yields continuous eigenvalues (growth rates in the unstable regime and real frequencies in the stable regime) with rather intriguing implications for the non-Hermitian nature of the rotating plasmas. Through the Laplace transform, as well as numerical simulations, interesting long-term behavior of the instability has been found.
The giant component of the random bipartite graph

The random bipartite graph G(m,n; p) is the random graph obtained by taking the complete bipartite graph Km,n and deleting each edge independently with probability 1− p. Using a branching process argument, the threshold function for a giant connected component in G(m,n; p) is found to be 1/ √ mn, and the number of vertices in the giant component is proportional to √ mn. An attempt is made to reduce the study of G(m,n; p) to the well-studied random graph G(m,p) using an original argument, and this is used to show that a.a. s. the giant of G(m,n; p) is cyclic when m = o(n) and p √ mn is large enough. Using a colouring argument, similar results are shown for Fortuin-Kasteleyn’s random-cluster model with parameter 1 ≤ q ≤ 2 when m = o(n). In particular, when m = o(n) the critical inverse temperature for the Ising model on Km,n is found to be − 2 log ( 1− 2 √ mn ) , and the number of vertices in the giant is proportional to √ mn.
