description: We examined gender differences in age of onset, clinical course, and heritability of alcohol dependence in 2524 adults participating in the University of California San Francisco (UCSF) family study of alcoholism. Men were significantly more likely than women to have initiated regular drinking during adolescence. Onset of regular drinking was not found to be heritable but was found to be significantly associated with a shorter time to onset of alcohol dependence. A high degree of similarity in the sequence of alcohol-related life events was found between men and women, however, men experienced alcohol dependence symptoms at a younger age and women had a more rapid clinical course. Women were found to have a higher heritability estimate for alcohol dependence (h2 =0.46) than men (h2 =0.32). These findings suggest that environmental factors influencing the initiation of regular drinking rather than genetic factors associated with dependence may in part underlie some of the gender differences seen in the prevalence of alcohol dependence in this population.

description: Direct expressions for the magnetic anisotropy constants are given at a finite temperature from microscopic viewpoints. In the present derivation, it is assumed that the Hamiltonian is a linear function with respect to the magnetization direction. We discuss in detail the first-order constant $K_1$ and show that the results reproduce previous results. We also apply our method to Nd$_2$Fe$_{14}$B compounds and demonstrate that the temperature dependencies of the magnetocrystalline anisotropy constants $K_1$, $K_2$, and $K_3$ are successfully computed.

Character Displacement and the Origins of Diversity

description: In The Origin of Species, Darwin proposed his ‘principle of divergence of character’ (a process now termed ‘character displacement’) to explain how new species arise and why they differ from one other phenotypically. Darwin maintained that the origin of species, and the evolution of differences between them, is ultimately caused by divergent selection acting to minimize competitive interactions between initially similar individuals, populations, and species. Here, we examine the empirical support for the various claims that constitute Darwin’s principle, specifically that: (1) competition promotes divergent trait evolution; (2) the strength of competitively mediated divergent selection increases with increasing phenotypic similarity between competitors; (3) divergence can occur within species; and (4) competitively mediated divergence can trigger speciation. We also explore aspects that Darwin failed to consider. In particular, we describe how: (1) divergence can arise from selection acting to lessen reproductive interactions; (2) divergence is fueled by the intersection of character displacement and sexual selection; and (3) phenotypic plasticity may play a key role in promoting character displacement. Generally, character displacement is well supported empirically, and it remains a vital explanation for how new species arise and diversify.

description: In the present study, the total protein and amino acid composition of smooth scallop (Flexopecten glaber) meat sampled every month for one year was determined in the Çardak Lagoon (Turkey). The lowest protein level in smooth scallop meat (57.41% dry weight, dw) was found in December, whereas the highest protein level was observed in April (67.62% dw). Essential amino acid concentrations ranged from 16.60 to 20.82 g.100 g-1 dw, while non-essential amino acid concentrations ranged from 36.03 to 46.68 g.100 g-1 dw. Among essential amino acids, phenylalanine was dominant. The highest essential amino acid contents were observed in winter and spring, while the highest non-essential amino acid contents were observed in summer and autumn. The differences in monthly essential amino acids and non-essential amino acid values were statistically significant (p < 0.05).
Erroneous Arrhenius: Modified Arrhenius Model Best Explains the Temperature Dependence of Ectotherm Fitness
Creators: name: Kingsolver, Joel G.
name: Knies, Jennifer L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The initial rise of fitness that occurs with increasing temperature is attributed to Arrhenius kinetics, in which rates of reaction increase exponentially with increasing temperature. Models based on Arrhenius typically assume single rate-limiting reaction(s) over some physiological temperature range for which all the rate-limiting enzymes are in 100% active conformation. We test this assumption using datasets for microbes that have measurements of fitness (intrinsic rate of population growth) at many temperatures and over a broad temperature range, and for diverse ectotherms that have measurements at fewer temperatures. When measurements are available at many temperatures, strictly Arrhenius kinetics is rejected over the physiological temperature range. However, over a narrower temperature range, we cannot reject strictly Arrhenius kinetics. The temperature range also affects estimates of the temperature dependence of fitness. These results indicate that Arrhenius kinetics only apply over a narrow range of temperatures for ectotherms, complicating attempts to identify general patterns of temperature dependence.

description: There is a considerable knowledge gap regarding the ecology and biogeography of blennies (Family Blenniidae) in Pakistan. To address this, we performed an extensive coastal survey from Pakistan's Sindh and Balochistan provinces in 2018 and 2019. The goal of the survey was to inventory the presence of members of rockskippers of the family Blenniidae, provide detailed description of the collected specimens, and describe otolith shape and camouflage efficiency in natural and captive environments. We focused our analysis and description on six species of the family Blenniidae (n = 53) including Antennablennius bifilum (n = 12), Blenniella cyanostigma (n = 12), Istiblennius edentulous (n = 17), Istiblennius spilotus (n = 1), Pereulixia kosiensis (n = 9), and Praealticus striatus (n = 2). Sagitta otoliths (right side) were extracted and detailed descriptions are provided. Camouflage efficiency was categorized as immediate, moderate, or low for each species. This was done by making visual observations of individuals in natural and captive environments. This study documents, for the first time, the presence of six rockskipper from the study area and the camouflage capacity of different species. These data enhance information about ornamental fishes in the region to promote conservation and management.
Computing Confidence Bounds for Power and Sample Size of the General Linear Univariate Model

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: The power of a test, the probability of rejecting the null hypothesis in favor of an alternative, may be computed using estimates of one or more distributional parameters. Statisticians frequently fix mean values and calculate power or sample size using a variance estimate from an existing study. Hence computed power becomes a random variable for a fixed sample size. Likewise, the sample size necessary to achieve a fixed power varies randomly. Standard statistical practice requires reporting uncertainty associated with such point estimates. Previous authors studied an asymptotically unbiased method of obtaining confidence intervals for noncentrality and power of the general linear univariate model in this setting. We provide exact confidence intervals for noncentrality, power, and sample size. Such confidence intervals, particularly one-sided intervals, help in planning a future study and in evaluating existing studies.

description: Fast scan cyclic voltammetry (FSCV) has been used previously to detect neurotransmitter release and reuptake in vivo. An advantage that FSCV has over other electrochemical techniques is its ability to distinguish neurotransmitters of interest (i.e. monoamines) from their metabolites using their respective characteristic cyclic voltammogram. While much has been learned with this technique, it has generally only been used in a single working electrode arrangement. Additionally, traditional electrode fabrication techniques tend to be difficult and somewhat irreproducible. Described in this report is a fabrication method for a FSCV compatible microelectrode array (FSCV-MEA) that is capable of functioning in vivo. The microfabrication techniques employed here allow for better reproducibility than traditional fabrication methods of carbon fiber microelectrodes, and enable batch fabrication of electrode arrays. The reproducibility and electrochemical qualities of the probes were assessed along with cross talk in vitro. Heterogeneous release of electrically stimulated dopamine was observed in real-time in the striatum of an anesthetized rat using the FSCV-MEA. The heterogeneous effects of pharmacology on the striatum was also observed and shown to be consistent across multiple animals.

description: The increase in anthropogenic pressure and microbial discharges into the Marchica lagoon requires continuous studies to assess the quality of water and sediments. The seasonal and spatial variations in bacterial levels in samples of seawater and sediments of the Marchica lagoon, collected monthly from January to December 2018 from six different locations, were investigated. The physico-chemical parameters of seawater were measured simultaneously during the sampling of bacterial loads to evaluate the correlation between abiotic factors and bacterial indicators. Bacterial loads were cultured on selective media and estimated as the number of colony-forming units for water and sediment samples. The seasonal variations significantly affected (P < 0.05) the concentrations of fecal coliforms (FC) and fecal streptococci (FS) in seawater as well as in sediments. The highest bacterial population were recorded in autumn/winter and the lowest values were observed in summer. Regarding the spatial distribution, fecal indicator bacteria are significantly higher (P < 0.05) at the Bou-Areg site (S5) than other stations which were attributed to the discharge of poorly treated sewage and the animal faeces used as fertilizer for agriculture. The bacterial populations were larger in sediment samples than in seawater. Temperature and salinity were negatively correlated with fecal indicators (FC and FS). Overall, this study shows that there is low risk for human health, based upon international guidelines regarding seawater quality. These results provide an understanding of the variations of abundance and persistence of bacterial indicators in seawater and sediment of the Marchica Lagoon.

description: Lattice birth-and-death Markov dynamics of particle systems with spins from the set of non-negative integers are constructed as unique solutions to certain stochastic equations. Pathwise uniqueness, strong existence, Markov property and joint uniqueness in law are proven, and a martingale characterization of the process is given. Sufficient conditions for the existence of an invariant distribution are formulated in terms of Lyapunov functions. We apply obtained results to discrete analogs of the Bolker--Pacala--Dieckmann--Law model and an aggregation model.

description: We report the imaging of β-cyclodextrin/benzoic acid binding at 14T using hyperpolarized 13C magnetic resonance (MR). Benzoic acid was polarized using a dynamic nuclear polarization (DNP) approach and combined with β-cyclodextrin in aqueous solution. As anticipated, decreases in the spin-lattice relaxation constant (T1) were observed with decreases in the ligand/ receptor ratio. The calculated log K was approximately 1.7, similar to previously reported binding constants. Hyperpolarized [1-13C] benzoic acid was used to interrogate solutions of variable β-cyclodextrin concentration, with the mixtures imaged at 14T using a 3D frequency-selective MR sequence. Differences in β-cyclodextrin concentration were easily visualized. These results suggest that hyperpolarized 13C MR could be used in vivo to determine the presence, and density of receptors for a given ligand-receptor pair.

description: Generalizing matrix models, tensor models generate dynamical triangulations in any dimension and support a $1/N$ expansion. Using the intermediate field representation we explicitly rewrite a quartic tensor model as a field theory for a fluctuation field around a vacuum state corresponding to the resummation of the entire leading order in $1/N$ (a resummation of the melonic family). We then prove that the critical regime in which the continuum limit in the sense of dynamical triangulations is reached is precisely a phase transition in the field theory sense for the fluctuation field.

description: On March 2020, the Soldierbream Argyrops filamentosus (Valenciennes, 1830) was spotted in the Specially Protected Areas of Zembra island (eastern Tunisia) during the implementation of regular monitoring activities. One single individual was later captured nearby by gillnets at 60 m depth. This record stands for the second reported observation of this species in the Mediterranean Sea, its first occurrence being documented in Turkey on October 2015. The importance of a joint strategy for detecting non-indigenous species and other biodiversity changes in Mediterranean Marine Protected areas was raised and discussed.

description: We give a method for constructing a Legendrian representative of a knot in $S^3$ which realizes its maximal Thurston-Bennequin number under a certain condition. The method utilizes Stein handle decompositions of $D^4$, and the resulting Legendrian representative is often very complicated (relative to the complexity of the topological knot type). As an application, we construct infinitely many knots in $S^3$ each of which yields a reducible 3-manifold by a Legendrian surgery in the standard tight contact structure. This disproves a conjecture of Lidman and Sivek.

description: The east Atlantic-Mediterranean Melicertus kerathurus and the west Atlantic invader Penaeus aztecus co-exist in the Thermaikos Gulf (Aegean Sea) and the two penaeid prawns are exploited by both artisanal and trawl fisheries. The bulk of catches for otter trawling consisted of M. kerathurus. Αrtisanal fishery catches for both species presented significant monthly fluctuations: Catch Per Unit Effort (CPUE) of M. kerathurus being higher in summer, whereas for P. aztecus in early autumn. For both species size frequency distributions and medians differed significantly between sexes, in favor of females. Females and males P. aztecus have a significant higher median size than the respective of M kerathurus. Sex ratio of M. kerathurus from the artisanal fishery showed a significant monthly differentiation, with males dominating in June and July whereas females from August to October. Females P. aztecus outnumbered males in catches for both trawl and artisanal fisheries. The two species have prolonged reproductive periods which overlap, but with distinctive spawning peaks: M. kerathurus in mid-July and P. aztecus in September-October. It is documented that P. aztecus is well established in the Thermaikos Gulf and has not led to any up-to-date bathymetric displacement or to the extinction of M. kerathurus.

Macrofaunal associates of marine sponges of the Andaman Islands (India), with a focus on Biemna fortis (Topsent, 1897) and its symbionts

description: Research on sponge-associated macrofauna from India is scarce. The current study provides a preliminary account of sponge associated macrofauna from the Andaman Islands with a focus on Biemna fortis (Topsent, 1897) and its symbionts. At least 24 species in six phyla were found associated with 15 host sponges species. Among them, number of individuals of the associated fauna was highest in Paratetilla bacca (29), while 12 sponges had only one associated species. These observations were, however, based on one sponge specimen each and does not reflect the actual numerical and taxonomical compositon of the associated fauna. Altogether, a total of 564 individuals representing 9 endofaunal taxa (belonging to six phyla) were found from B. fortis. The fauna most frequently associated with B. fortis are Ophiactis savigny with a mean ± SE of 31 ± 6.1 individuals followed by Nereis sp., Gonodactylus sp., anomuran crabs, hermit crabs (Paguroidea), juvenile stomatopods and Gastropoda (Conus sp. and polyplacophora). Brittle stars and polychaetes were common associates of B. foris irrespective of the sampling sites. Polycladida, bivalves (Pectinidae) and Sipuncula were observed occasionally within the canals. Endofaunal assemblage of Biema fortis was dominated by: Brittle stars > Polychaetes > Crabs. Oscule size of the sampled Biemna fortis ranged from 2 to 12 mm in diameter. Brittle stars were particularly abundant in sponges having oscules 5-6 mm in diameter, which highlights the importance of oscule size in limiting the potential predators that can enter the host. The high specificity of juvenile brittle stars and their mortality without sponge habitats suggests an obligate relationship, while other associated polychaetes and crustaceans could be facultative sponge commensals. Interactions between host sponges and their symbionts await further experimental demonstration for understanding their ecology.

description: The stability of an Abl kinase substrate peptide in a cytosolic lysate and in single cells was characterized. In the cytosolic lysate, the starting peptide was metabolized at an average initial rate of 1.7 ± 0.3 zmol pg−;1 s−;1 with a t1/2 of 1.3 min. Five different fragments formed over time; however, a dominant cleavage site was identified. Multiple rational design cycles were utilized to develop a lead peptide with a phenylalanine and alanine replaced by an (N-methyl)phenylalanine and isoleucine, respectively, to attain cytosolic peptidase resistance while maintaining Abl substrate efficacy. This lead peptide possessed a 15-fold greater lifetime in the cytosolic lysate while attaining a 7-fold improvement in kcat as an Abl kinase substrate compared to the starting peptide. However, when loaded into single cells, the starting peptide and lead peptide possessed nearly identical degradation rates and an altered pattern of fragmentation relative to that in cell lysates. Preferential accumulation of a fragment with cleavage at an Ala-Ala bond in single cells suggested that dissimilar peptidases act on the peptides in the lysate versus single cells. A design strategy for peptide stabilization, analogous to that demonstrated for the lysate, should be effective for stabilization in single cells.

description: Scanty information is available on the accumulation of heavy metals in mantis shrimps (stomatopods). Present study is a pioneer attempt from Pakistan to determine heavy metal contents in two species (Oratosquillina interrupta and Miyakella nepa). This study focused on a comparative analysis of heavy metals concentrations (Fe, Mn, Pb, Hg, Cu, Zn and Cd) in these stomatopods from the Korangi Fish Harbor (Karachi, Pakistan) from February 2019 to December 2019. All samples were analyzed by using the AAnalyst 700 Flame Atomic Absorption Spectrophotometer. It was observed that the average concentrations (µg.g-1) of Fe, Mn, Pb, Hg, Cu, Zn and Cd in muscle were, respectively: 4.308 ± 1.078, 0.352 ± 0.155, 0.022 ± 0.021, 0.001 ± 0.002, 1.373 ± 0.625, 1.943 ± 0.700 and 0.035 ± 0.031 µg g-1 for O. interrupta. For the same metals sequence in M. nepa these values in muscle were 4.342 ± 2.051, 0.507 ± 0.239, 0.036 ± 0.033, 0.004 ± 0.006, 0.407 ± 0.228, 1.852 ± 0.672 and 0.032 ± 0.031 µg g-1, respectively. Metal accumulations in muscle tissues of these species from Korangi Fish Harbour did not exceed limit values. However, with the increase in daily seafood consumption, these results are moving towards the point of danger.

description: A microengineered array to sample clonal colonies is described. The cells were cultured on an array of individually releasable elements until the colonies expanded to cover multiple elements. Single elements were released using a laser-based system and collected to sample cells from individual colonies. A greater than an 85% rate in splitting and collecting colonies was achieved using a 3-dimensional cup-like design or “microcup”. Surface modification using patterned titanium deposition of the glass substrate improved the stability of microcup adhesion to the glass while enabling minimization of the laser energy for splitting the colonies. Smaller microcup dimensions and slotting the microcup walls reduced the time needed for colonies to expand into multiple microcups. The stem cell colony retained on the array and the collected fraction within released microcups remained undifferentiated and viable. The colony samples were characterized by both reporter gene expression and a destructive assay (PCR) to identify target colonies. The platform is envisioned as a means to rapidly establish cell lines using a destructive assay to identify desired clones.

These may survive some decades but then probably expire due to coastal erosion. Single non-flowering plants infrequently occur on the high shores of west, south-west and southern coasts. Most of these do not survive winter storms. This study examines the distribution of recently stranded pea seeds and of plastics found on the same shores. In 1992, a small flowering clone was found on the south coast of Ireland. This site was revisited on eleven occasions with counts of plants during its expansion over a period of twenty-nine years. In 2020 transects were supplemented with aerial images to evaluate the distribution and abundance which had increased to some thousands of plants. Despite some human interference and coastal erosion, the population may continue to survive some decades. Evidence based on the distribution of stranded pea seeds and origin of associated plastics, together with ocean currents and predominant wind directions indicate a likely source from the east coast of North America.

description: We study the evolution of the quantum state of $n$ photons in $m$ different modes when they go through a lossless linear optical system. We show that there are quantum evolution operators $U$ that cannot be built with linear optics alone unless the number of photons or the number of modes is equal to one. The evolution for single photons can be controlled with the known realization of any unitary proved by Reck, Zeilinger, Bernstein and Bertani. The evolution for a single mode corresponds to the trivial evolution in a phase shifter. We analyze these two cases and prove that any other combination of the number of photons and modes produces a Hilbert state too big for the linear optics system to give any desired evolution.

description: Plerocercus larvae of Callitetrarhynchus parvus sp. nov. (Trypanorhyncha: Lacistorhynchidae) were collected from commercially exploited fish, the black Scorpionfish Scorpaena porcus Linnaeus, 1758, the white grouper Epinephelus aeneus (Geoffroy Saint-Hilaire, 1817) and the dusky grouper Epinephelus marginatus (Lowe, 1834) from Tunisian waters. The prevalence of plerocerci larvae recorded in the three hosts were low 1.4%, 9.4% and 12.5%, respectively. The blastocysts were found attached to the external stomach wall of infected fish. Light and scanning electron microscopical observations of larvae showed a scolex with two bothria, a poeciloacanthous atypical, heteromorphous metabasal armature, with 7 hooks, one intercalary hook and one chainette. Hook 7(7') was unicate with an anterior extension at the base (BR = 3.86-6.38:1). Molecular characterization of the rDNA regions (SSU, LSU and ITS) confirmed that the species was included in the genus Callitetrarhynchus. The phylogenetic analysis carried using the SSU rDNA and LSU rDNA concatenated complement the characterization of the new species by defining its phylogenetic position among the species of the family Lacistorhynchidae Guiart, 1937. Molecular analysis revealed a high genetic distance between C. parvus sp. nov. and its congeners from the Callitetrarhynchus genus.

description: Energy transfer through the food-chain is one of the principal processes determining the ecosystem functioning. However, food habits of important consumers are still poorly investigated in many ecosystems. The Argentinean menhaden Brevoortia pectinata is an important fishery resource of small-scale fishery industry and a conspicuous species in southwestern Atlantic estuaries. The feeding habits of this species is unknown, despite its commercial and ecological relevance. We analyzed 227 gut contents of juvenile menhadens sampled in Patos Lagoon estuary in south Brazil (32°S) to describe spatial patterns in its diet composition and trophic plasticity associated with salinity conditions. Overall, B. pectinata consumed mainly calanoid copepods and diatoms showing diet shifts along the salinity gradient. The diet was dominated by calanoids (40%) and diatoms (25%) in the sampling station nearer the lagoon's connection with the sea, but shifted to cladocerans (63%) and calanoids (90%) in the intermediate estuary and nearer freshwater, respectively. The diet was also more diverse towards the sea connection, with higher contribution of marine taxa like barnacle larvae and amphipods. Hence, this planktivore species presented an omnivore diet and trophic plasticity along the salinity gradient, being apparently adapted to the different availability of food resources in each portion of the estuary.

description: A cell separation strategy capable of the systematic isolation and collection of moderate to large numbers (25–400) of single cells into a targeted microwell is demonstrated. An array of microfabricated, releasable, transparent micron-scale pedestals termed pallets and an array of microwells in poly(dimethylsiloxane) (PDMS) were mated to enable selective release and retrieval of individual cells. Cells cultured on a pallet array mounted on a custom designed stage permitted the array to be positioned independently of the microwell locations. Individual pallets containing cells were detached in a targeted fashion using a pulsed Nd:YAG laser. The location of the laser focal point was optimized to transfer individual pallets to designated microwells. In a large-scale sort (n = 401), the accuracy, defined as placing a pallet in the intended well, was 94% and the collection efficiency was 100%. Multiple pallets were observed in only 4% of the targeted wells. In cell sorting experiments, the technique provided a yield and purity of target cells identified by their fluorescence signature of 91% and 93%, respectively. Cell viability based on single-cell cloning efficiency at 72 h post collection was 77%.

description: Galactic Gamma-Ray Bursts (GRBs) are copious sources of gamma-rays that can pose a threat to complex life. Using recent determinations of their rate and the probability of GRBs causing massive extinction, we explore what type of universes are most likely to harbour advanced forms of life. For this purpose we use cosmological N-body simulations to determine at what time and for what value of the cosmological constant ($Λ$) the chances of life being unaffected by cosmic explosions are maximised. We find that $Λ-$dominated universes favour the survival of life against GRBs. Within a $Λ$CDM cosmology, the parameters that govern the likelihood of life survival to GRBs are dictated by the value of $Λ$ and the age of the Universe. We find that we seem to live in a favorable point in this parameter phase space which minimises the exposure to cosmic explosions, yet maximises the number of main sequence (hydrogen-burning) stars around which advanced life forms can exist.

description: A strategy was developed to extend the lifetime of an peptide-based substrate for Abl kinase in the cytosolic environment. Small β-turn structures were added to the peptide’s N-terminus to block entry into peptidase catalytic sites. The influence of the size of the β-turn and two covalent cross-linking strategies on the rate of hydrolysis was assessed. The most peptidase-resistant substrate was degraded at a rate of 0.6 pmol mg−1 s−1 and possessed a half-life of 20.3 ± 1.7 min in a Baf/BCR-ABL cytosolic lysate, representing 16- and 40-fold improvements, respectively, over that of a control peptide lacking the β-turn structure. Furthermore, the kcat/KM value of this peptide was 432 μM−1 min−1, a 1.25X increase over the unmodified control, verifying that the added β-turn did not hinder the substrate properties of the peptide. This improved peptide was microinjected into single Baf/BCR-ABL cells and substrate phosphorylation measured. Zero to forty percent of the peptide was phosphorylated in the single cells. In contrast, when the control peptide without a β-turn was loaded into cells, the peptide was too rapidly degraded to detect phosphorylation. This work demonstrates that small β-turn structures can render peptides more resistant to hydrolysis while retaining substrate efficacy and shows that these stabilized peptides have the potential to be of high utility in single-cell enzyme assays.

description: Il successo degli strumenti di tutela collettiva, che si misura in termini di efficienza e deterrenza delle condotte illecite, dipende dagli obiettivi che i legislatori perseguono. Le scelte compiute in Brasile, con l’adozione del nuovo c.p.c., paiono il sintomo di una certa disaffezione nei confronti della tutela giurisdizionale collettiva; in Europa, invece, i conati di armonizzazione si scontrano con l’eterogeneità delle scelte sinora compiute dagli ordinamenti interni, nonché con il ruolo complementare che gli strumenti di private enforcement sono destinati a svolgere in settori nevralgici del mercato.

description: The theoretical assertion that the Fano asymmetry parameter and the asymptotic initial phase of a harmonic oscillator interacting with a continuum are interrelated is experimentally verified. By an example of coherent fully symmetric A1g phonons in bismuth that are excited by ultrashort laser pulses at liquid helium temperature, it is demonstrated that, for negative values of the asymmetry parameter, the asymptotic phase increases as the modulus of the parameter decreases.

Some Issues on Optimal Non-Linear Taxation
Creators: name: COHEN, FRANCESCO
Publisher: name: Universit� degli Studi di Milano

description: In this thesis we apply an optimal taxation approach to analyze how citizens' private information may affect Social Planner 's goal of redistribution across individuals. In fi rst two Chapters, we allow individuals to emigrate to a laissez-faire country. Chapter 1 assumes the existence of two types of citizens, who are endowed with a different labor productivity. We let these two types be low- and high-skilled, respectively, and assume that emigration is costly. We prove that low-skilled agents ' incentive compatibility constraint is never binding at the optimum, while high-skilled citizens' one is. Moreover, these latter are net taxpayers and, hence, a lump-sum tax is levied by the Social Planner. Relative to the standard closed-economy model, we also fi nd that, if the economy stands for two periods, in the absence of Government 's commitment, redistribution is dramatically reduced by the existence of high-skilled citizens' outside opportunity. Therfore, an inducing fi rst-period pooling tax scheme is much less likely to be implemented, with respect to a separating tax scheme. In Chapter 2 we introduce a third type of citizens, who are characterized by an intermediate skill level. This allows us to better analyze the distributive effects of taxation. In particular, we will show that countervailing incentives may occur. Indeed, medium-type citizens may fi nd it optimal to mimic high-skilled ones. In a such a context, a separating scheme can be implemented. However, a distortion at the top arises. As in Chapter 1, Chapter 3 studies an economy, that is populated by two continua of individuals, who differ in labor productivity. We allow agents to save and let effort be private information. Therefore, both adverse selection and moral hazard problems may arise. In particular, we prove that, under adverse selection, it is optimal for the Social Planner to fully insure high-skilled agents and to over-insure low-skilled ones. Moreover, no high-type aggregate intertemporal wedge is implemented, while a positive L-aggregate intertemporal wedge is obtained. Finally, we study the joint effects of dynamic moral hazard and adverse selection on social welfare. In this case, both types are partially insured. Moreover, both the H-aggregate intertemporal wedge and the L-aggregate intertemporal wedge are positive.
