description: The invariant mass method is used to identify the $^8$Be and $^9$B nuclei and Hoyle state formed in dissociation of relativistic nuclei in a nuclear track emulsion. It is shown that to identify these extremely short-lived states in the case of the isotopes $^9$Be, $^{10}$B, $^{10}$C, $^{11}$C, $^{12}$C, and $^{16}$O, it is sufficient to determine the invariant mass as a function of the angles in pairs and triples of He and H fragments in the approximation of the conservation of momentum per nucleon of the parent nucleus. According to the criteria established in this way, the contribution of these three unstable states was evaluated in the relativistic fragmentation of the $^{28}$Si and $^{197}$Au nuclei.

description: Tidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing approx (0.3--23)% of the local density of our Galactic Halo. If the Sagittarius galaxy contains WIMP dark matter, the extra contribution from the stream gives rise to a step-like feature in the energy recoil spectrum in direct dark matter detection. For our best estimate of stream velocity (300 km/sec) and direction (the plane containing the Sgr dwarf and its debris), the count rate is maximum on June 28 and minimum on December 27 (for most recoil energies), and the location of the step oscillates yearly with a phase opposite to that of the count rate. In the CDMS experiment, for 60 GeV WIMPs, the location of the step oscillates between 35 and 42 keV, and for the most favorable stream density, the stream should be detectable at the 11 sigma level in four years of data with 10 keV energy bins. Planned large detectors like XENON, CryoArray and the directional detector DRIFT may also be able to identify the Sgr stream.

description: A new N3-tridentate imine ligand, 2,6-diacetylpyridinediphenylhydrazone (DAPH) (L), and its Pd(II), V(IV)O, and Ag(I) complexes were synthesized and characterized via elemental analysis, FT-IR, NMR, molar conductance, and magnetic susceptibility measurements. The obtained data confirmed geometrical structures of Pd(II), Ag(I), and V(IV)O complexes as square planar, tetrahedral, and distorted square pyramidal, respectively. Minimum inhibitory concentrations (MIC) were used to probe in vitro antimicrobial activity of DAPH ligand and metal complexes using three different bacteria. Results revealed that PdDAPH complex exhibited the highest toxicity and lowest MIC (1.25 µg/mL) toward Escherichia coli. Moreover, cytotoxic activity of the prepared complexes was evaluated via three human cancer cell lines, hepatic carcinoma (HepG2), breast carcinoma (MCF-7), and colon carcinoma (HCT-116). Among all tested complexes, PdDAPH caused a significant loss of cell viability in less time and lower dose than the reference drug vinblastine. Antioxidant activity was also measured for all complexes and compared to vitamin C. Probing the interaction of the prepared metal-DAPH chelates with calf-thymus DNA showed the Pd(II) complex displayed the strongest interaction, with a binding constant of 6.02 kcal mol−1. Molecular docking was also investigated on all complexes, with PdDAPH being the most promising compound due to its facile hydrophobic interactions with the active pocket of glucose transporter (GLUT1) enzyme. Overall, the combined findings of this work clearly demonstrate that these new compounds hold promise as efficient antibiotic and anticancer agents.
Challenges in Preserving Neuroimaging Research Data
Creators: name: Whyte, Angus
Publisher: name: Zenodo
Year: 2008

description: Preserving neuroimaging research data for sharing and re-use involves practical challenges for those concerned in its use and curation. These are exemplified in a case study of a psychiatry research group. The study is one of a series encompassing two aims; firstly to discover more about disciplinary approaches and attitudes to digital curation through "immersion" in selected cases; secondly to apply known good practice, and where possible to identify new lessons from practice in the selected discipline areas. These aims were addressed through ethnographic study of current practices, and action research to assess risks, challenges, and opportunities for change. The challenges are in some ways archetypal of fields that are embracing "e-science;" how to reconfigure practice to improve data sharing and re-use, given the capabilities afforded by "cyberinfrastructure. " The evolution of those in neuroimaging is tied to the social and technological infrastructure underpinning the domain, and imaging centres such as the psychiatric research group in question. Its preservation challenges may be understood by examining relationships between its history, nature of the data collected, innovations in analysis, practices of sharing data and methods, and the evolution of data repositories in the domain.

description: Using results from colloid science we derive interaction potentials for computer simulations of mixtures of soft or hard ellipsoids of arbitrary shape and size. Our results are in many respects reminicent of potentials of the Gay-Berne type but have a well-defined microscopic interpretation and no adjustable parameters. Since our potentials require the calculation of similar variables, the modification of existing simulation codes for Gay-Berne potentials is straightforward. The computational performance should remain unaffected.

Aligning Digital Preservation Policies with Community Standards
Creators: name: McGovern, Nancy
Publisher: name: Zenodo
Year: 2008

description: Digital preservation policies are an essential component of an organization's digital preservation program. Yet, recent surveys show that many organizations that manage digital content do not have an explicit policy statement to delineate the mandate, purpose, scope, principles, and objectives of their digital preservation program. The Digital Preservation Management workshop series developed at Cornell University by Anne R. Kenney and Nancy Y. McGovern (Digital Preservation Officer at ICPSR) between 2003 and 2006 produced version 1.0 of a digital preservation policy framework. The resulting framework is a high-level policy document that is structured to be sharable with other organizations. Version 2.0 of the digital preservation policy framework was developed and tested at ICPSR. It builds on the Cornell model by aligning the components of the framework with the attributes of a trusted digital repository and incorporating key components of the Open Archival Information System (OAIS) Reference Model. This paper will discuss the digital preservation policy framework, present examples from the version 1.0 and version 2.0 models, discuss the structure and development of a comprehensive set of digital preservation policies for an organization, consider the connections between recent research and development on policy engines for digital preservation, and propose next steps for community policy development.

description: In this article, we report Mn(II), Fe(II) and Cu(I) complexes (BIP-Mn, BIP-Fe and BIP-Cu) bearing a non-innocent, NNN pincer ligand, 4-aminoantipyrine tethered 2,6-bis(iminoantipyrine)pyridine (BIP) and structural diversity. The complexes were characterized by different spectroscopic and single-crystal X-ray analysis. Superoxide dismutase (SOD) activity has been evaluated for BIP and complexes BIP-Mn, BIP-Fe and BIP-Cu. It was observed that the seven-coordinate BIP-Mn complex showed preeminent SOD activity on comparing to BIP-Fe and BIP-Cu complexes. Besides, preliminary in vitro anticancer properties of BIP-Mn, BIP-Fe and BIP-Cu have been studied. Again, BIP-Mn complex showed stronger anticancer activity compared to ligand, BIP-Fe and BIP-Cu complexes.

description: The validity of two fundamental concepts of classical chemical kinetics - the notion of "Chemical Equilibrium" and the "Law of Mass Action" - are re-examined for reversible \textit{diffusion-limited} reactions (DLR), as exemplified here by association/dissociation $A+A \rightleftharpoons B$ reactions. We consider a general model of long-ranged reactions, such that any pair of $A$ particles, separated by distance $μ$, may react with probability $ω_+(μ)$, and any $B$ may dissociate with probability $ω_-(λ)$ into a geminate pair of $A$s separated by distance $λ$. Within an exact analytical approach, we show that the asymptotic state attained by reversible DLR at $t = \infty$ is generally \textit{not a true thermodynamic equilibrium}, but rather a non-equilibrium steady-state, and that the Law of Mass Action is invalid. The classical picture holds \text{only} in physically unrealistic case when $ω_+(μ) \equiv ω_-(μ)$ for any value of $μ$.

description: We observe an anomalous oxygen isotope effect on the a-axis component of the far-infrared electronic response of detwinned YBa2Cu3$^{16,18}$O$_{6.9}$. For $^{18}$O a pronounced low-energy electronic mode (LEM) appears around 240 cm$^{-1}$. This a-axis LEM exhibits a clear aging effect, after one year it is shifted to 190 cm$^{-1}$. For $^{16}$O we cannot resolve a corresponding a-axis LEM above 120 cm$^{-1}$. We interpret the LEM in terms of a collective electronic mode that is pinned by `isotopic defects', i.e. by the residual $^{16}$O in the matrix of $^{18}$O.

description: Aims: Our goal is to investigate how the strength of episodic accretion bursts depends on eccentricity. Methods: We investigate the binary trigger hypothesis in longer-period (>20yr) binaries by carrying out three-dimensional magnetohydrodynamical (MHD) simulations of the formation of low-mass binary stars down to final separations of $\sim$10$\au$, including the effects of gas turbulence and magnetic fields. We ran two simulations with an initial turbulent gas core of one solar mass each and two different initial turbulent Mach numbers, M = 0.1 and M=0.2, for 6500yr after protostar formation. Results: We observe bursts of accretion at periastron during the early stages when the eccentricity of the binary system is still high. We find that this correlation between bursts of accretion and passing periastron breaks down at later stages because of the gradual circularisation of the orbits. For eccentricities greater than e=0.2, we observe episodic accretion triggered near periastron. However, we do not find any strong correlation between the strength of episodic accretion and eccentricity. The strength of accretion is defined as the ratio of the burst accretion rate to the quiescent accretion rate.We determine that accretion events are likely triggered by torques between the rotation of the circumstellar disc and the approaching binary stars. We compare our results with observational data of episodic accretion in short-period binaries and find good agreement between our simulations and the observations. Conclusions: We conclude that episodic accretion is a universal mechanism operating in eccentric young binary-star systems, independent of separation, and it should be observable in long-period binaries as well as in short-period binaries. Nevertheless, the strength depends on the torques and hence the separation at periastron.

#nomorelonely : building community with 1 trillion trees
Creators: name: Baker, Gary P
Publisher: name: The University of British Columbia
Year: 2021

description: During 2020, in an effort to help curb the climate crisis, the World Economic Forum announced a campaign to grow, restore and conserve one trillion trees around the world by 2050, the year by which the United Nations projects two-thirds of our global population will be urban dwellers. In the meantime, another alarming life-threatening crisis is expanding across our metropolises where social isolation is deepening amid densification: loneliness in the city. By analyzing variations in the use of woodlands and forests in urban places, I will offer proposals for how landscape architects can work with trees in their designs of neighbourhood spaces to respond in tandem to curb the climate crisis and loneliness. In positing that the forest is the city, I will identify opportunities to engage Vancouverites in the design, planning, planting, and caring for the trees in their neighbourhoods. With an advent of responsible stewardship of the urban canopy and reciprocity in the relationships to be formed with neighbourhood woodlands and with other neighbourhood residents, I will suggest that these proposals could help to ameliorate experiences of loneliness while addressing elements of our climate crisis.

description: Amid the recent uptake of Generative AI, sociotechnical scholars and critics have traced a multitude of resulting harms, with analyses largely focused on values and axiology (e.g., bias). While value-based analyses are crucial, we argue that ontologies -- concerning what we allow ourselves to think or talk about -- is a vital but under-recognized dimension in analyzing these systems. Proposing a need for a practice-based engagement with ontologies, we offer four orientations for considering ontologies in design: pluralism, groundedness, liveliness, and enactment. We share examples of potentialities that are opened up through these orientations across the entire LLM development pipeline by conducting two ontological analyses: examining the responses of four LLM-based chatbots in a prompting exercise, and analyzing the architecture of an LLM-based agent simulation. We conclude by sharing opportunities and limitations of working with ontologies in the design and development of sociotechnical systems.

description: This paper examines the effect of remittances on household spending in Kenya using household survey data from World Bank 2009 African Migration Project. A fractional multinomial logit model is used to estimate the effect of remittances on the share of expenditure on food, education, health, investments, consumer durables, housing and land, and ‘others’.The results indicate that external remittances increase the share of total household expenditure allocated to education, consumer durables and housing and reduce the share of total household expendituredevoted to food and physical investments. Internal remittance has a positive effect on the share of total household expenditure devoted to food. Once endogeneity is controlled for, external remittances have a positive effect on household spending on investment while internal remittances reduce the share of expenditure on education and ‘others’.

description: We study transport through strongly interacting quantum dots with $N$ energy levels that are weakly coupled to generic multi-channel metallic leads. In the regime of coherent sequential tunneling, where level spacing and broadening are of the same order but small compared to temperature, we present a unified, $SU(N)$-invariant form of the kinetic equation for the reduced density matrix of the dot and the tunneling current. This is achieved by introducing the concept of flavor polarization for the dot and the reservoirs, and splitting the kinetic equation in terms of flavor accumulation, anisotropic flavor relaxation, as well as exchange-field- and detuning-induced flavor rotation. In particular, we identify the exchange field as the cause of negative differential conductance at off-resonance bias voltages appearing in generic quantum-dot models. To illustrate the notion of flavor polarization, we analyze the non-linear current through a triple quantum-dot device.

description: This study explores the effect of public debt on private investment in Tanzania. Secondary data for the period of 1970-2016 were collected from National Bureau of Statistics (Tanzania), Bank of Tanzania, World Bank, and scholarly journals. An Autoregressive Distributed Lag (ARDL) bound test to cointegration is used in this study. Results suggest a significant evidence of nonlinear long run and short run relationship between external debt and private investment. However, Granger causality test suggests that this relationship is rather a co-movement than causal. At 5% level of significance, there is no significant evidence of long run and short run relationship between domestic debt and debt service on one hand, and private investment on the other hand. However, the combined effect of domestic and external debt on private investment is statistically significant both in long run and short run. The study recommends the government to adopt strict policies on project implementations to ensure positive returns of borrowed funds and closely monitoring of public debt, particularly external debt on which private investment is more responsive than domestic debt and debt service, despite its sustainability at present.

description: N-Heterocycles are structural constituents of pharmaceuticals based on FDA approved therapeutic agents with more than 60% of drugs containing N-heterocycles as building blocks. In the present study, a 1,10-phenanthroline derivative with metal acetates forms metal chelates of the type [MIIL], where L = 1,10-phenanthroline derivative and M = Co(II), Zn(II), Cu(II) and Ni(II). They were characterized by analysis, spectra [IR, UV–vis, (1H and 13C) NMR, mass, ESR] and magnetism as well as thermal analysis for the structural elucidation. Spectroscopic and analytical measurements confirmed an octahedral geometry for the Co(II), Zn(II), Cu(II) and Ni(II) chelates. The antimicrobial efficacy of the prepared complexes was assessed against Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Aspergillus flavus, Candida albicans and Aspergillus niger. The antimycobacterial efficacy of the 1,10-phenanthroline derivative and its chelates was assessed against H37Rv using Microplate Alamar Blue Assay approach and compared with a standard. The acetylcholinesterase (AChE) inhibitory effect of the ligand was examined to find the therapeutic efficiency of compound in the treatment of neurodegenerative diseases. The synthesized ligand exhibited selective inhibition against AChE and butyryl-cholinesterase with IC50 values of 0.20 and 3.20 µM as compared to standards, rivastigmine and galantamine. Further, the in vitro anti-inflammatory efficiency of metal chelates was examined with the help of egg albumin method. The α-glucosidase inhibition activity was also carried out for the prepared metal complexes.

description: This study investigated the effect of tax reforms, economic growth and political environment on total tax, direct tax and indirect tax revenues using annual data for the period 1964-2016. Various techniques of analysis were employed: descriptive statistics, multi-segment regressions and non-linear regression. Results show that: all taxes responded positively to each of the tax reforms; changes in all taxes were affected by the reforms because GDP was also growing; economic growth has positive significant effect on all the categories of taxes; Government effectiveness has positive impact on indirect taxes; and that even though government control of corruption effect on tax revenues is statistically insignificant, it could promote the revenue generation more than economic growth. These findings have a number of policy implications: the government should put more emphasis on governance in order to promote revenue collection. Government effectiveness and control of corruption would go a long way to enhance tax compliance, reduce tax avoidance and evasion, eliminate illicit flows and reduce illegal collusion between tax payer and tax administrator that may deprive government of due revenues. Secondly, government must work towards designing and implementing in the reforms that make the tax system more buoyant, and link it more to economic growth.

description: This paper assesses the importance of non-pecuniary factors on tax compliance in Sub-Saharan Africa (SSA). In addition, the paper examines how legal origins affect tax compliance factors. Using the Round 5 of the Afrobarometer survey data across 29 countries, the findings revealed that non-pecuniary factors in the form of tax knowledge limitation; non-compliance by others; and corruption of tax officials are associated with reductions in the probability of tax compliance in SSA. On the contrary, factors such as trust in tax department; handling the provision of health, education and road needs, tend to be associated with increase the probability of complying with tax laws and obligations in SSA. In terms of legal origins, institutions and fiscal exchange have bigger association with compliance for common law countries (British origin) and civil law countries (French origin) respectively.
We Inhabit the Same World: Integrating Socio-economic and Environmental Data

Publisher: name: Zenodo
Year: 2008

description: The Rural Economy and Land Use programme provides examples of how interdisciplinary research projects carried out by teams of social and natural scientists combine the use of socio-economic and environmental data. Data may be integrated through spatial integration (GIS), modelling, relational databases or data conceptualisations and visualisations. Integrations must take into account differences in data scale, area and framework. Whilst social science data are usually organised according to administrative areas, natural science data are based on grids or ecological zoning. Researchers use different approaches to optimise communication between such diverging data. Experiences of data integration also provide information on how best to organise and archive data to enable their long-term use within various research disciplines.

description: Two water-soluble dicationic complexes, [Cu(bipy)(dipn)](BF4)2 (1) and [Cu(bipy)(dipn)](NO3)2 (2) (bipy = 2.2-bipyridine and dipn = dipropylenetriamine), were synthesized in high yields. The desired complexes were characterized by CHN-EA, UV–Vis, SEM, EDS, FT-IR, TGA, and XRD. The single-crystal XRD of [Cu(bipy)(dipn)](BF4)2 reflected that Cu(II) complex is formed in a distorted square pyramid configuration. The Hirshfeld surface analysis (HSA) confirmed more powerful atom–atom interaction, the hydrogen bonding in H…F, supporting the outcome of XRD. The influences of the CT-DNA/complexes were gathered by viscosity, CV, and electronic absorption measurements. The estimated binding constants (Kb) for 1 and 2 were 4.5 × 104 and 3.4 × 104 M−1, respectively. Complex 2 revealed slightly poorer DNA binding capability than 1. Eventually, the molecular docking of [Cu(bipy)(dipn)]+2 species was evaluated and demonstrated employing 1BNA-DNA segment.

description: Energy system optimization models (ESOMs) should be used in an interactive way to uncover knife-edge solutions, explore alternative system configurations, and suggest different ways to achieve policy objectives under conditions of deep uncertainty. In this paper, we do so by employing an existing optimization technique called modeling to generate alternatives (MGA), which involves a change in the model structure in order to systematically explore the near-optimal decision space. The MGA capability is incorporated into Tools for Energy Model Optimization and Analysis (Temoa), an open source framework that also includes a technology rich, bottom up ESOM. In this analysis, Temoa is used to explore alternative energy futures in a simplified single region energy system that represents the U.S. electric sector and a portion of the light duty transport sector. Given the dataset limitations, we place greater emphasis on the methodological approach rather than specific results.

description: This paper examines the citizen's trust in government and their willingness to pay taxes to improve public goods and services in Tanzania. We use logit model to estimate the effect of government trust on willingness to pay taxes on improved public goods/services. Chi square test finds an association between citizen's trust in government and their willingness to pay taxes for improved public good/services. Logit estimations show that an increase of one unit of public service delivery is associated with increase of citizen's trust in the government. Furthermore, we find that taxpayers are dissatisfied with public services/goods provided by the government. Only 43.5% of citizens showed an average satisfaction on public services delivery. The policy implication is that, providing better public services to the society is an effective tool to raise tax revenues in the government.

description: The EDDA-Detector at the Cooler-Synchrotron COSY/Jülich has been operated with an internal CH$_2$ fiber target to measure proton-proton elastic scattering differential cross sections. For the data analysis knowledge of beam parameters, like position, width and angle, are indispensable. We have developed a method to obtain these values with high precision from the azimuthal and polar angles of the ejectiles only, by exploiting the coplanarity of the two final state protons with the beam and the kinematic correlation. The formalism is described and results for beam parameters obtained during beam acceleration are given.

description: The study employed data from 1970 to 2014 to forecast government non-oil revenues and non-oil exports in Nigeria in an attempt to know the number of years it would take non-oil incomes to outpace the income from oil sources using Autoregressive Integrated Moving Average (ARIMA) Model. The results show that non-oil revenue of government will match the size of 2014 government oil revenue in 2023 (9 years), while it would take 466 years for non-oil exports to achieve the oil exports equivalence. However, it would take non-oil revenues and non-oil exports 14 years and 565 years respectively to achieve the 2011 historic highest oil incomes (oil revenues and oil exports) of 8,878.97 Billion Naira and 14,323.20 Billion Naira. Meanwhile, if non-oil revenue increases annually by 15 percent, using 2014 as base year, the target could be achieved in 2025 (11 years), but it would take non-oil exports annual increase of 18 percent to hit the target in 2030 (26 years). It is thus suggested that, while the current government revenue mobilization and strategies be maintained, the government efforts on export promotions vis-à-vis non-oil diversifications must be more than doubled in order to upturn the oil dependent Nigerian economy to non-oil economic base before the year 2050.

description: Transition metal dichalcogenides like MoS2 can exist many phases like the semiconducting 2H and the metallic 1T phases which have shown intriguing properties for energy and electrocatalytic applications. However, the 2H and 1T phases normally distribute coherently in a single-layered MoS2 sheet which is accompanied with ubiquitous hetero-phase boundaries. In this work, by using density functional theory and electrochemical measurement, we report strong charge transfer ability between 2H/1T phase boundary of MoS2 and graphene which accounts for a superb coexistence of gravimetric and volumetric capacitances of 272 F g-1 and 685 F cm-3. As a proof-of-concept application, a flexible solid-state asymmetric supercapacitor based on MoS2/graphene is fabricated, showing a remarkable energy and power densities (46.3 mWh cm-3 and 3.013 Wcm-3). Our work shows the promise of promoting the efficiency of charge flow and energy storage through engineering phase boundary and interface in phase-change materials.

description: Four ball-type phthalocyanines (H2Pc, MgPc, CoPc, and ZnPc) containing 4-tert-butylcatechol substituents at alpha-positions were synthesized from 3,3′-(4-tert-butyl-1,2-phenylene)bis(oxy)diphthalonitrile. The structures were elucidated by elemental analysis and ultraviolet-visible, Fourier-transform infrared, proton nuclear magnetic resonance, and Maldi-Tof mass spectroscopies. The photophysicochemical properties of H2Pc, MgPc, and ZnPc were investigated in dimethylsulphoxide. The fluorescence quantum yields (ΦF), triplet state quantum yields (ΦT), and singlet oxygen quantum yields (ΦΔ) with respect to H2Pc, MgPc and ZnPc were experimentally obtained. Furthermore, the degradation quantum yield (Φd) was evaluated for all complexes. Finally, the magnetic circular dichroism spectra of the four Pcs were obtained. Among these ball-type phthalocyanines, MgPc had the highest triplet lifetime and ZnPc had the highest singlet oxygen quantum yield. Moreover, the in vitro antiproliferative effect of ball-type phthalocyanines (H2Pc, MgPc, CoPc, and ZnPc) was evaluated on MCF-7 cell line originated from luminal A breast cancer and MDA-MB-231 cell line originated from triple negative breast cancer. For this purpose, cell viability MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used. For all compounds, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, 25.6, 51.2, 102.4 µM concentrations were applied to both cell lines. There was a significant decrease in cell viability for MCF-7 and MDA-MB-231 cells (p

description: Drift velocity and longitudinal diffusion measurements are reported for a Negative Ion TPC (NITPC) operating with Helium + carbon disulfide gas mixtures at total pressures from 160 to 700 torr. Longitudinal diffusion at the thermal-limit was observed for drift fields up to at least 700 V/cm in all gas mixtures tested. The results are of particular interest in connection with mechanical simplification of Dark Matter searches such as DRIFT, and for high energy physics experiments in which a low-Z, low density, gaseous tracking detector with no appreciable Lorentz drift is needed for operation in very high magnetic fields.

Publisher: name: Zenodo
Year: 2008

description: In Germany, process-generated data and survey data on firms are collected by different data producers. Each data producer provides access for researchers to its data, but the combination of datasets from different producers is not possible at the moment. The KombiFiD project aims to overcome this limitation: firm data collected by the German Statistical Offices, the German Central Bank and the Federal Employment Agency will be merged for the first time. Our goals are twofold: to gauge the possibilities of merging selected datasets beyond the limits of individual labour market data producers, and to provide combined datasets to science, thereby creating new research opportunities. Our presentation outlines the status quo of the project. We describe the datasets selected for merging and explain potential merging problems. Moreover we address research questions which can be analyzed for the first time with the unique new data. Amongst others, this is the possibility to monitor the history of businesses on the basis of their combined single units.

description: In spite of several attempts by donors, financial institutions, government and the society at large to eradicate age-old poverty, Nigeria has walloped in generational poverty as a result of many contending factors among which mismanagement of aid and grant obtainable are leading contenders. In evaluating its objectives, this paper adopts the Augmented Dickey-Fuller test to ascertain the order of integration of the variables and Autoregressive distributed lag (ARDL) approach to account for the short run and long run dynamics of a level relationship between economic growth and foreign aid alongside relevant macroeconomic indicators. Findings reveal that there exist a long run relationship among economic growth and foreign aid to Nigeria. The paper finds out that gross capital formation significantly impacts on economic growth positively. Foreign aid exhibits a positive relationship, but it is not seen to determine economic growth in Nigeria. The study concludes that past aid to Nigeria has not been effective or it does not constitute what drives growth in the country. It also invalidates the applicability of the Two-Gap Theory squabble for Nigeria, since foreign aid is seen not to be significant.
