description: We propose a new approach to PoS tagging where in a first step, we assign a coarse-grained tag corresponding to the main syntactic category. Based on this high-precision decision, in the second step we utilize specially trained fine-grained models with heavily reduced decision complexity. By analyzing the system under oracle conditions, we show that there is a quite large potential for significantly outperforming a competitive baseline. When we take error-propagation from the coarse-grained tagging into account, our approach is on par with the state of the art. Our approach also allows tailoring the tagger towards recognizing single word classes which are of interest e.g. for researchers searching for specific phenomena in large corpora. In a case study, we significantly outperform a standard model that also makes use of the same optimizations.

description: The 2019 novel coronavirus disease (COVID-19) has devastated health and economic systems worldwide with varying impacts across different economic sectors. Projections of its impact in early 2020 were that developing countries in the global south with historic system inefficiencies would be the worst hit, as weaknesses in their economies would be exposed by the pressure the pandemic would place on health, food and economic systems. Global evidence on the impacts of COVID-19 on economic livelihoods suggests that the most vulnerable income sources to COVID-related shocks would be temporary wage income as opposed to permanent wage income, primarily because casual work that requires day to day contact would be less due to social distancing requirements and movement restrictions (Diao and Mahrt, 2020). Also, national and household food security and nutrition would be negatively impacted, mostly through loss or reduction in household income (both formal and informal sectors) and disruption of supply chains due to movement restrictions within and across countries (Mofya-Mukuka et al., 2020; GRZb, 2020). In Zambia, it has been expected that food consumption would be reduced as the informal sector, which employs over 70 percent of the country’s population, would be hardest hit – particularly for those in agriculture and trade (wholesale and retail) (CUTS and UNDP, 2020). Current local evidence shows that urban households are bearing the brunt of impact compared to their rural counterparts and the sources of impact include price gouging, reduced customers, and reduced business income (Kabisa et al., 2020; Mulenga et al., 2020; Mofya-Mukuka et al., 2020). This brief aims to contribute to the local evidence on the impact that COVID-19 has had on incomes and food security in Zambia. This study complements nationwide-surveys documenting the impact the pandemic is having in real time on the economic livelihoods of Zambians in both rural and urban areas, and tracking food consumption changes during the course of the pandemic. This is in order to provide empirical evidence to guide government policy interventions. This brief is organized as follows: Section 2 gives a brief overview of how the Zambian government has responded to the COVID-19 pandemic and this is followed by a summary of the data collection methods in Section 3. The survey results are discussed in Section 4 and conclusions of the findings and their policy implications are summarized in Section 5.
Machine learning, real-time techniques for the discovery, analysis and study of Fast Radio Bursts

description: Fast Radio Bursts (FRBs) are brief, bright flashes observed in the radio spectrum whose origins remain a mystery. Originating from half-way through the universe, and carrying the imprint of the media they propagate through on their billion-year-long journey, these bursts promise to further our understanding of the cosmos. This thesis describes an FRB survey performed using the Molonglo Radio Telescope. With the aid of a machine learning signal processing algorithm developed as part of this work, 6 new bursts were discovered. Noteably, and at the time of discovery, one of them was the first to be studied at the finest time resolution.

description: Ostrya rehderiana is a famous plant species with extremely small populations. With ongoing global climate change, the extremely small populations would face more uncertainties and risks, including the loss of genetic diversity and extirpation. Thus, assessing the impact of climate change on suitable habitat of O. rehderiana is particularly important for its conservation and restoration. Here, we built niche models with climate variables and soil and human footprint variables. Furthermore, new methods were applied to avoid confounding effects between climate and soil and human footprint variables to simulate the potential habitats of O. rehderiana in current and future climates. We found that the Hargreaves climatic moisture deficit, degree-days below 0 °C, chilling degree-days, and the temperature difference between mean warmest month temperature and mean coldest month temperature, or continentality, were the most important climate factors. The topsoil USDA texture classification, topsoil cation exchange capacity of (clay), and topsoil sodicity (ESP) were the key soil factors determining the suitable distribution of O. rehderiana. Compared with soil factors, human footprint has less influence on the suitable distribution of O. rehderiana. The niche range of this species was projected to expand and shift to north in the Representative Concentration Pathway (RCP) 4.5 scenario for the 2050s. Our study results could be referenced in further extremely small populations ecological restoration studies and provide the scientific strategies for the conservation and restoration of O. rehderiana.

description: Historically, ports and cities have a very close relationship with each other; this relationship is rooted in the port as the trading point around which the city develops due to the beneficial impact of the trading activity. As the port grows, it requires more space for its operations, which reduces the space available for human development. Inhabitants of the city must then relocate to other areas, which requires improving the city’s interconnectivity and increasing both inland and out-of-port land transport links. As a result, vehicle traffic increases because most land transport is by truck. The increase in vehicle traffic may bring about a decline in the standard of living of the population (because of congestion and/or road safety issues) and may also increase transport costs due to longer transport times in heavy traffic. A study of congestion reports by Waze, TomTom and INRIX has revealed severe traffic disruption in port cities such as Buenos Aires, Sao Paulo, Los Angeles, Valencia, and Jakarta. The environmental impact of congestion is mostly negative because it can affect air, water and soil quality, reduce biodiversity, increase noise and waste, and ulti-mately lead to risks to human health. Thus, new concepts for healthier port-cities relationships should be developed. TUL- Study, July 2020

description: We perform a comparison of 22 PoS tagger models for English and German offered by 9 different implementations. By evaluating on a mix of corpora from different domains, we simulate a black-box usage where researchers select a tagger (because of popularity, ease of use, etc.) and apply it to all sorts of text. We find the expected trade-off between fast models with relatively low accuracy and slower models with higher accuracy. The choice of the model, even for the same tagger, does matter and the model should always be chosen for the task at hand. Our evaluation provides researchers with a basis for selecting taggers according to their needs.

description: Lexical recognition tests are frequently used for measuring language proficiency. In such tests, learners need to differentiate between words and artificial nonwords that look much like real words. Our goal is to automatically generate word-like nonwords which enables repeated automated testing. We compare different ranking strategy and find that our best strategy (a specialized higher-order character-based language model) creates word-like nonwords. We evaluate our nonwords in a user study and find that our automatically generated test yields scores that are highly correlated with a well-established lexical recognition test which was manually created.

description: In second language learning, cloze tests (also known as fill-in-the-blank tests) are frequently used for assessing the learning progress of students. While preparation effort for these tests is low, scoring needs to be done manually, as there usually is a huge number of correct solutions. In this paper, we examine whether the ambiguity of cloze items can be lowered to a point where automatic scoring becomes possible. We utilize the local context of a word to collect evidence of low-ambiguity. We do that by seeking for collocated word sequences, but also taking structural information on sentence level into account. We evaluate the effectiveness of our method in a user study on cloze items ranked by our method. For the top-ranked items (lowest ambiguity) the subjects provide the target word significantly more often than for the bottom-ranked items (59.9% vs. 36.5%). While this shows the potential of our method, we did not succeed in fully eliminating ambiguity. Thus, further research is necessary before fully automatic scoring becomes possible.

An Examination of the Human Fibrinogen-like Protein2:  Sequence Variations and Genetic Expression by Human Endothelial Cells
Creators: name: Jenkins, Meredith
Publisher: name: Georgia State University
Year: 2006

description: A role for Fgl2 (fibroleukin) in thrombophilic-associated human fetal loss has been indicated by previous studies.  Clotting of vascular vessels of the placenta and fetus interferes with adequate blood circulation.   The human Fgl2 gene was sequenced with identification of six SNPs, suggesting an association with a population of women suffering from recurrent fetal losses. A small sample size however, prevented precise statistical analyses of this association.  In vitro, human endothelial cells (HUVECs) were not found to constitutively express Fgl2, but were shown to up-regulate its expression when challenged with IFN-? and TNF-à.  Interestingly, TNF-à was only shown to induce expression of Fgl2 in HUVECs from male donors and not female donors.   A larger case-control study is needed to examine the relationship of Fgl2 with recurrent fetal loss. The role of estrogen in the Th1-induced expression of Fgl2 by HUVECs should also be examined.

Age and Sex Differences in the Acquisition and Maintenance of Intravenous Amphetamine Self-Administration in Rats
Creators: name: Shahbazi, Mahin
Publisher: name: Georgia State University
Year: 2006

description: Drug abuse peaks during adolescence, and exposure to drugs during adolescence predicts drug abuse in adulthood. Nevertheless, adolescence is not widely studied in animal models of drug intake. Moreover, few studies have investigated sex differences in drug-reinforced behavior during adolescence. We studied age- and sex-differences in acquisition and maintenance of amphetamine self-administration in Sprague-Dawley rats. Adolescent males took more amphetamine than adult males, supporting the hypothesis that adolescents are more sensitive to amphetamine. A high rate of ?inappropriate? active lever presses among periadolescent males suggests impulsive behavior. In the maintenance phase of testing, young adult males failed to work as hard as adult males. In contrast, young adult females worked harder than adult females. Comparing sex groups, young adult females worked harder than age-matched males to obtain amphetamine. These results will ultimately help to form effective treatment and prevention programs for drug dependent individuals of all ages and both sexes.
Functional Analysis of the Murine Oligoadenylate Synthetase 1b (Oas1b)
Creators: name: Elbahesh, Husni
Publisher: name: Georgia State University
Year: 2006

description: The flavivirus resistance gene, Flv, in mice has been identified as 2'-5' oligoadenylate synthetase 1b (Oas1b). Susceptible mice produce a protein that is truncated (Oas1btr) at the C-terminus due to a premature stop codon encoded by a C820T transition. Mice produce 8 Oas1 proteins, Oas1a-Oas1h. In the present study, Oas1a, Oas1b and Oas1btr were expressed as MBP-fusion proteins in bacteria and purified. 2-5A synthetase activity was demonstrated using MBP-Oas1a, while neither MBP-Oas1b nor MBP-Oas1btr were functionally active. The 2-5A synthetase activity of MBP-Oas1a was inhibited in a dose-dependent manner by the addition of MBP-Oas1b but not MBPOas1btr. Finally, three RNA probes were synthesized from the 3' end of the WNV Eg101 genome and used to test the ability of the expressed Oas1 proteins to bind to viral RNA. Results of the RNA binding activity assays suggest Oas1 proteins may specifically interact with regions of WNV RNA.

description: This thesis critiques the dehumanising industrial food system. Then proposes a design framework where people can relate to their food, bodies, communities, institutions and nature in a convivial and holistic way. Drawing on living systems theory and the authors own food system design experiments in everyday life, Samuels-Ballantyne proposes convivial design as a relational and tactical way to design what she terms as convivial food systems and a convivial life (convivial self). Convivial design is diverse in its scope, enabling designers to implement local small scale projects and larger educational and policy making programs.

Neurolipofuscin is a Measure of Age in the Caribbean Spiny Lobster, Panulirus argus, in Florida
Creators: name: Maxwell, Kerry
Publisher: name: Georgia State University
Year: 2006

description: Accurate age estimates for the commercially-important Caribbean spiny lobster, Panulirus argus, would greatly enhance analyses of life history and population dynamics. Previous estimates of their age based on size and growth may be inaccurate because of variable growth in the wild. An established technique for aging crustaceans ? histologically-determined lipofuscin content in the nervous system ? was used on lobsters reared in the laboratory for up to five years. We verified the presence of lipofuscin in eyestalk neural tissue and described its distribution in cell cluster A of the hemiellipsoid body. Neurolipofuscin content of both sexes increased linearly over the five-year age range, with seasonal oscillations. Growth of these animals, on the other hand, showed sex differences and began to asymptote after three years. Neurolipofuscin concentrations in the two eyestalks from the same animal were similar. These results suggest that the neurolipofuscin technique will be valuable for estimating age of wild-caught P.argus.

description: Neglected tropical diseases (NTDs) remain a significant public health challenge, disproportionately affecting impoverished populations in tropical and subtropical regions. Despite substantial progress in combating certain infectious diseases, vaccine development for NTDs has lagged due to economic, scientific, and logistical barriers. Recent advancements in biotechnology, such as mRNA vaccines and omics technologies, offer new opportunities to accelerate vaccine discovery and development for NTDs. This review examines the current state of vaccine development for major NTDs, including Chagas disease, leishmaniasis, and schistosomiasis. We discuss the challenges involved in developing vaccines for these diseases, the role of public-private partnerships, and innovative approaches to enhance vaccine access and efficacy. Moreover, this review highlights the importance of global initiatives and funding mechanisms such as the London Declaration on NTDs, which emphasize international collaboration to end the neglect of these diseases. The aim of this work is to provide a comprehensive overview of the scientific and economic strategies needed to advance vaccine development and access for NTDs, ultimately reducing their global burden.

Septal Infusions of the H-Channel Blocker ZD7288 Impair Spontaneous Alternation but not Inhibitory Avoidance
Creators: name: Cisse, Ramata
Publisher: name: Georgia State University
Year: 2006

description: It is well established that the septo-hippocampal system is involved in memory. The medial septum is connected to the hippocampus via the fimbria fornix, which consists mostly of acetylcholine and ?-aminobutyric acid (GABA) projection neurons. The contributions of the cholinergic projection to memory have been studied extensively; whereas, the role of the GABAergic projection is not well characterized. The present experiment tested whether septal infusions of the selective H-channel blocker ZD7288 would impair spontaneous alternation (SA) and continuous multiple inhibitory avoidance (CMIA). Fifteen minutes prior to assessing SA or CMIA, different groups of male Sprague-Dawley rats were given septal infusions of saline or ZD7288 (0.2, 0.6 or 1.5 nmol / 0.5l). Our results indicate that septal infusions of ZD7288 impaired SA in a dose-dependent manner; the same infusions did not affect CMIA. This is the first demonstration that H-channels on septo-hippocampal GABAergic projection neurons are involved in memory.

description: As the use of nickel-titanium (NiTi) file systems for root canal therapy has become popular; hence, knowledge and understanding of the characteristics of NiTi files is essential for dentists. Unintended sudden fracture can occur during root canal shaping, and it is important to understand the conditions that may cause instrument fractures. Torque is defined as the force required to rotate the NiTi file and can be considered of as a parameter for the stress generated. The endodontic engine maintains a constant rotational speed by adjusting torque regardless of the root canal conditions. The process of root canal shaping by rotary instruments is a series of actions that requires torque and generates stress to both the teeth and the NiTi instruments. The generated stress may induce the strain accumulation on NiTi instrument and the canal wall and lead to the development of microcrack in the instrument and dentinal wall. Therefore, understanding of torque and stress generated is important to prevent the fractures to the instrument and the teeth. This stress has been measured using various experimental approaches, including microcrack observation by using a microscope or computed tomography, attaching strain gauges to the teeth, and finite element analysis. This review focuses on the stress generated to the teeth and the instrument during instrumentation under various experimental conditions. The factors related to torque generation are also discussed.
An Integrative Analysis of Reproduction and Stress in Free-Living Male Cottonmouths, Agkistrodon Piscivorus

description: I conducted an integrative field study on male cottonmouths (Agkistrodon piscivorus), a common pitviper of the southeastern United States, to investigate the evolution of contrasting mating patterns in North American pitvipers (bimodal and unimodal annual patterns) and resolve conflicting information about the pattern exhibited by the cottonmouth. I determined a unimodal late summer peak of testosterone (T) and a muted unimodal seasonal cycle of the sexual segment of the kidney (a secondary sexual characteristic), both of which were correlated with the single peak of spermatogenesis in late summer. I also conducted a study to determine diel and seasonal variation of corticosterone (CORT), the effect of captive handling on CORT, and the relationship between CORT and T after captive handling, and detected a significant elevation of CORT and a significant decrease of T after capture in male cottonmouths, as well as a significant negative correlation between CORT and T.

Die Studie zeigt (im statistischen Durchschnitt) einige bemerkenswerte Unterschiede in den Arbeitsbedingungen von Arbeitgebern und Arbeitnehmern auf. Andererseits sind Unternehmer sehr häufig mit ganz ähnlichen Arbeitsbedingungen wie ihre Mitarbeiter konfrontiert. Eine interessante Mittelstellung nehmen die so genannten „Solo‐Selbstständigen“ ein. Eines der hervorstechendsten Ergebnisse der Studie ist die hohe Konstanz der Resultate, sowohl bei den relativen Häufigkeiten als auch im Hinblick auf zentrale Zusammenhänge ergeben sich über die drei Erhebungszeiträume hinweg allenfalls geringfügige Unterschiede.

The Role of S7, A Subunit of the 19S Proteasome, in the Transcriptional Regulation of MHC II.
Creators: name: Gerhardt, Dawson
Publisher: name: Georgia State University
Year: 2006

description: Induction of an adaptive, or antigen specific, immune response is critical for eliminating most infections. Pathogen clearance is accomplished primarily, by the actions of CD4+ T cells through their ability to recognize foreign antigens presented at the cell surface by major histocompatibility class II (MHC II) molecules. Consequently, the capacity to regulate expression of MHC molecules is essential to control the adaptive immune response. MHC molecules are regulated at the level of transcription by a master regulator, the class II transcriptional activator, CIITA.  Thus, the expression of MHC II is directly related to proper CIITA activity. This thesis focuses on the novel role of S7, an ATPase subunit of the 19S proteasome, in the transcriptional regulation of CIITA and MHC II molecules.

description: This repository corresponds to the electronic supplementary information of the article "Linking selection to demography in experimental evolution of active death in a unicellular organism".

This study reports on our experimental explorations of eco-evolutionary dynamics in an puzzling context: active cell death leading to population decline in response to environmental stress.We tracked the population dynamics of two closely related strains of the halotolerant microalga Dunaliella salina (they differ in whether or not they trigger programmed cell death), in competition over 13 cycles of salinity rise (about 180 generations).
description: Deciphering how natural selection emerges from demographic differences among genotypes, and reciprocally how evolution affects population dynamics, is key to understanding population responses to environmental stress. This is especially true in non-trivial ecological scenarios, such as programmed cell death (PCD) in unicellular organisms, which can lead to massive population decline in response to stress. To understand how selection may operate on this trait, we exposed monocultures and mixtures of two closely related strains of the microalga Dunalliela salina, one of which induces PCD, to multiple cycles of hyper-osmotic shocks, and tracked demography and selection throughout. Population dynamics were consistent between mixtures and monocultures, suggesting that selection on PCD does not involve strong ecological interactions. The PCD-inducing strain was maintained throughout the experiment despite an initial decline, by a combination of fast population rebound following each decline, and density-dependent competition dynamics near the stationary phase that were independent of these initial population fluctuations. As result of PCD maintenance, population decline in response to environmental stress was not counter-selected in our experiment, but persisted over 13 cycles of salinity. Our results highlight how analysing the demographic underpinnings of fitness and competition can shed light on the mechanisms underlying selection and eco-evolutionary dynamics.

Isolation and Characterization of the Y32G9A.8 Promoter in C. elegans

description: The over-expression of Down syndrome cell adhesion molecules (DSCAMs) is partially responsible for the mental retardation associated with Down syndrome. Previous work in our lab showed that a DSCAM homolog in C. elegans, Y32G9A.8, is expressed at all developmental stages and appears to be crucial for survival. In an effort to map the expression pattern, I used the Genome Sciences Centre?s primer design program (http://elegans.bcgsc.bc.ca/gfp_primers/) to design a GFP promoter fusion product that was used to monitor gene expression. The results indicate that Y32G9A.8 is expressed in the animal?s gut, suggesting that it may function in the worm?s innate immune response. I also designed a primer set to amplify the Y32G9A.8 transcript. RT-PCR of the entire Y32G9A.8 coding region resulted in a single product; there appears to be no alternative splicing. Although this gene shows homology to other N-CAMS, results indicate that this gene may function in the innate immune system of C. elegans.

subject: 331 Arbeitsökonomie

description: Im vorliegenden Beitrag geht es um die Veränderung der Arbeitszufriedenheit und um die Identifikation von zeitlichen Verlaufsmustern der Arbeitszufriedenheit. Als Grundlage der Analyse dienen die Daten des Sozioökonomischen Panels aus mittlerweile 35 Erhebungswellen (1984 bis 2018). Die Analyse umfasst 3.345 Zeitreihen, die jeweils einen Zeitraum von 15 Jahren umspannen. Zur Typisierung der einzelnen Arbeitszufriedenheitsverläufe werden die Regressionsrechnung und die Clusteranalyse verwendet. Der Haupttypus folgt dem generellen Trend, wonach die Arbeitszufriedenheit, von einem mäßig hohen Niveau ausgehend, stagniert bzw. sich im Lauf der Zeit leicht vermindert. Es gibt daneben allerdings auch Fälle, die auf einem hohen Arbeitszufriedenheitsniveau verbleiben. Und auf der anderen Seite findet man nicht wenige Personen, deren Arbeitszufriedenheit im negativen Bereich verharrt. Eine weitere Gruppe wird von Personen gebildet, deren Arbeits-zufriedenheit relativ großen Schwankungen ausgesetzt ist. Von den soziographischen Variablen Alter, Geschlecht und Berufsstatus gehen keine nennenswerten Wirkungen aus. Eine gesonderte Betrachtung der Unternehmensgröße erbringt, dass Personen, die dauerhaft in einem Kleinbetrieb arbeiten, eine größere Arbeitszufriedenheit aufweisen als Personen in größeren Unternehmen. Neben der Darstellung der inhaltlichen Einsichten, die die Zeitreihenanalyse erbringt, erfolgt eine Diskussion über die Verwendung der Modellergebnisse für auf die Zukunft gerichtete Szenario-Analyse.

description: The effects of a four arm hammer cracker/ beater on the performance of a newly developed palm kernel cracking machine has been investigated. The work evaluated the performance of the machine with the four arm hammer head attached to it under constant load test. The shaft cracking speed was however, varied from 800 -1600 rpm during this period several parameters were measured. The result showed that as the shaft speed was increasing the cracking time of the palm kernel shells was decreasing. The shortest cracking time of 29.20 seconds occurred at a shaft speed of 1600 rpm while processing 3000g of palm kernels. At a shaft speed of 800 rpm the number of whole nuts was 473, this number increased to 529 at 1000 rpm and continued to decrease to 209 at 1600 rpm. At a shaft speed of 800 rpm the number of un-cracked nut was 21 as the speed continue to increase the number of un cracked nut decreased to 11 at 1000 rpm and continue to decrease to 1 at 1600 rpm, which means as the speed increases the number of un-cracked nut decreases. The work also discovered that the highest effective capacity using the four-arm hammer beater was 102.74 and occurred at the shaft speed of 1600 rpm, likewise the highest cracking efficiency of 99.84 occurred at 1600 rpm. The highest performance efficiency of 82.66 however, occurred at the four-arm hammer speed of 1000 rpm, considering other measured parameters like, number of whole nuts, number of broken nuts, performance efficiency, split nut loss, and overall efficiency the work concluded that the best operating speed for the newly developed palm cracker machine using the four-arm hammer beater is 1000 rpm.
Implant of a Selective Estrogen Receptor Alpha Agonist to the Male Rat Medial Preoptic Area Maintains Mating Behavior

description: ABSTRACT Evidence from knockout studies in male mice and from experiments in male rats,in which expression of the estrogen receptor alpha (ERà) gene was inhibited in the medial preoptic area (MPO), suggests that ERà is important in the control of male rat mating behavior. Therefore, in this experiment, we tested the hypothesis that activation of ERà in the MPO is sufficient to maintain mating behavior in castrated male rats receiving subcutaneously (s.c.) dihydrotestosterone (DHT), a non-aromatizable androgen. Accordingly, castrated rats treated with DHT s.c. received MPO implants of either: (i) propyl-pyrazole-triol (PPT) (Stauffer, et al 2000; Katzenellenbogen, et al 2000), a selective ERà agonist, (ii) E2 (positive controls) or (iii) cholesterol (negative controls)and sexual behavior was monitored. PPT was as effective as E2 at maintaining mating behavior suggesting that, in the MPO, ERà is sufficient to mediate responses to E2 that underlie male rat mating behavior.

description: Agricultural expansion has led to a significant loss of habitat and biodiversity in Ghana and throughout West Africa and the tropics generally. Most farmers adopt both organic and inorganic inputs to boost production, with the potential to slow agricultural expansion, but with relatively little consideration of related environmental impacts. In Ghana, where high-input modern farming is rapidly overtaking traditional organic agricultural practices, we examined five stakeholder groups in regard to their perceptions of the environmental, economic, and social costs and benefits of modern, mixed-input, and traditional farming systems. The stakeholder groups included farmers adopting different agricultural practices, as well as governmental and non-governmental natural resource managers. Our findings indicate that the overall perceived costs of modern farming, attributable to large quantities of inorganic inputs, are higher than the overall perceived benefits. Farmers are, however, still motivated to practice modern farming because of perceived higher returns on investment, regardless of environmental impacts, which they tend to discount. Traditional farmers do not use inorganic inputs and instead rely on swidden ‘slash-and-burn’ practices, resulting in declining productivity and soil fertility over time. Since traditional farmers are ultimately forced to encroach into nearby forests to maintain productivity, the perceived environmental sustainability of such farming systems is also limited. Mixed-input farming is not significantly different from modern farming with respect to its perceived environmental and economic traits, because it incorporates agro-chemicals alongside organic practices. Stakeholders’ perceptions and the apparent environmental outcomes of different farming systems suggest that reducing the use of inorganic inputs and promoting the adoption of organic inputs could minimise the negative impacts of agro-chemicals on the forest environment without necessarily compromising productivity. Campaigns to promote low-input or organic agriculture on environmental grounds in West Africa may falter if they fail to recognise farmers’ relatively favourable perceptions of the environmental implications of modern farming practices.
The Expression of p68 Protein in the Australian Zebra Finch Brain Across Development

description: Steroid hormones and receptors play a role in regulating biological events underlying brain development and sexual differentiation. Current evidence indicates that circulating sex steroid hormones are not entirely responsible for development of neural sex differences in song birds such as the zebra finch. p68, as a coactivator specific for estrogen receptor alpha (ERà) and an essential factor in early tissue development and maturation might play a role in sexual differentiation. Zebra finches have a sexually dimorphic song control nuclei in the brain, males have larger song nuclei than females, and are ideal model for investigating the mechanisms controlling sexual differentiation of the brain and behavior. Western blot analysis showed a significant sex difference at post hatch day 10 (P10). Immunohistochemistry showed localization of p68 immunoreactive cells in the ZF brain including nuclei that compose the avian song system. p68 is probably developmentally regulated and may be modulated by endogenous estrogen and estrogen receptors suggesting a role for p68 in sexual differentiation.
