description: We consider a stochastic process model with time trend and measurement error. We establish consistency and derive the limiting distributions of the maximum likelihood (ML) estimators of the covariance function parameters under a general asymptotic framework, including both the fixed domain and the increasing domain frameworks, even when the time trend model is misspecified or its complexity increases with the sample size. In particular, the convergence rates of the ML estimators are thoroughly characterized in terms of the growing rate of the domain and the degree of model misspecification/complexity.

The Effect of Credit Risk Management on the Profitability Performance of Commercial Bank of Ethiopia
Creators: name: Hiwot, Zemedkun
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The objective of the study was to assess the Effect of Credit Risk Management on the Profitability Performance of Commercial Bank of Ethiopia proxied by ROA and ROE, The study used a secondary data for the period between 2000 to 2018 for nineteen(19) years.The data was collected from CBE MIS Department,CBE Annual Report and National Bank of Ethiopia (NBE). The collected data was analyzed by using Time Series data regression model and EView7 software to regress the data , the result showed that credit risk management which is measured by non- performing loan to total loan ratio, and management efficiency that is measured by the ratio of operating expense to total income have negative and significant effect on both dependent variables (ROA and ROE).The other independent variables (CAR,TLTA,NII&LR) are insignificat.The study recommended that the bank's credit risk management needs strong attention & follow up regarding performer capacetiy building and to review their credit policey & procedure in order to minimize high incidence of NPL. This is because it has significant & negetive effect on the profitability of the bank, and also Management efficencey result shows that there is a lack of efficiency in expenses management since banks pass part of increased cost to customers and the remaining part to profits. Therefore, the CBE should also give more attention in reduction of expenses to improve its profitability of the industry.
Detecting People in Artwork with CNNs

description: CNNs have massively improved performance in object detection in photographs. However research into object detection in artwork remains limited. We show state-of-the-art performance on a challenging dataset, People-Art, which contains people from photos, cartoons and 41 different artwork movements. We achieve this high performance by fine-tuning a CNN for this task, thus also demonstrating that training CNNs on photos results in overfitting for photos: only the first three or four layers transfer from photos to artwork. Although the CNN's performance is the highest yet, it remains less than 60\% AP, suggesting further work is needed for the cross-depiction problem.

description: Formation of high spatial frequency laser induced periodic surface structures (HSFL) in germanium by femtosecond mid-IR pulses with wavelengths between $λ=2.0$ and $3.6 \; \mathrm{μm}$ was studied with varying angle of incidence and polarization. The period of these structures varied from $λ/3$ to $λ/8$. A modified surface-scattering model including Drude excitation and the optical Kerr effect explains spatial period scaling of HSFL across the mid-IR wavelengths. Transmission electron microscopy (TEM) shows the presence of a $30 \; \mathrm{n m}$ amorphous layer above the structure of crystalline germanium. Various mechanisms including two photon absorption and defect-induced amorphization are discussed as probable causes for the formation of this layer.

Identifying Forkhead Box Q1 as a novel regulator of ferroptosis

Subjects: subject: 500 Natural sciences

subject: 610 Medical sciences Medicine

description: Ferroptosis, an iron-dependent form of regulated cell death, is characterized by phospholipid peroxidation and metabolic constraint. Ferroptosis has emerged to play an important role in cancer biology to contribute into many pathologies. Cells respond to ferroptotic stimuli by regulation of selenoproteins, including the key regulator of ferroptosis phospholipid hydroperoxide-reducing enzyme glutathione peroxidase 4 (GPX4). Though, the underlying mechanisms and signalling pathways of ferroptotic cell death remain relatively unknown. Current research aims at deeper understanding of the pathophysiological role of ferroptosis and how it may be exploited for the treatment of cancer and neurodegenerative diseases. In this cell-based study, the GPX4 inhibitor (1S, 3R)-RSL3 (RAS selective lethal) and the system xc- (a cysteine/glutamate antiporter system) inhibitor erastin were used to identify Forkhead Box Q1 (FOXQ1) as a promising factor involved in the regulation of cellular ferroptosis sensitivity. The transcription factor FOXQ1 is a member of forkhead proteins that control important functions in biological development and tumorigenesis. A very limited number of studies have investigated the role of the FOXQ1 in human cancer. However, whether FOXQ1 and FOXQ1-regulated genes have a potentially predictable role in ferroptosis remains to be further explored, since pleiotropic responses in different cell lines were observed in the present study. An overexpression cloning approach was used to elucidate the factors and cell-autonomous mechanisms that underlie the regulation of ferroptosis in the given cell line. Present data suggest increased sensitivity to ferroptosis in FOXQ1 overexpressing cells compared to control cells. The finding was expanded to a panel of human breast cancer cell lines to show that overexpression of FOXQ1 mediated the sensitivity to RSL3- and erastin-induced ferroptotic cell death. To demonstrate the effect of FOXQ1 mediated sensitivity to ferroptosis in stably overexpressing cancer cell lines, several ferroptosis regulatory genes were monitored at several time points. In an attempt to further illuminate the mechanism of ferroptosis execution, targeted knock out (KO) of FOXQ1 in different cancer cell lines was performed using CRISPR/CAS technology, which resulted in reduced invasive ability of the cells. Furthermore, it was demonstrated that FOXQ1 deletion results in lower proliferation rates of cells and cell death. Consequently, various cancer cell lines overexpressing FOXQ1 were generated to enable investigations on the role of FOXQ1 and the role of novel transcriptional targets of FOXQ1 in ferroptosis that may serve as a potential therapeutic target for the development of anticancer therapies.

Towards a Whiter Woodlawn: Racism and the University of Chicago's Employer-Assisted Housing Program
Creators: name: Chen, Laurel
Publisher: name: Unknown
Year: 2020

description: This article investigates the racism inherent in the purportedly race-neutral University of Chicago’s Employer-Assisted Housing Program (EAHP) and its drive to encourage employee homeownership in the Woodlawn neighborhood. The paper demonstrates that the program’s eligibility requirements means it is most accessible to White people. It further shows that the EAHP marketing works to sell Woodlawn in specific ways in order to attract White homeowners despite the current racial makeup of a neighborhood that is majority-Black. Finally, in light of the University’s longstanding efforts to expand its physical sphere of influence through the creation of Whiter, wealthier spaces in neighboring communities, it outlines how staff, students, faculty, and broader community members might organize around the issue and put pressure on top administrators to alter such programs.

Major Challenges of Accessing Housing Project Finance in Addis Ababa
Creators: name: Girma, Yinebeb
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: In developing countries among important factors influencing housing provision, finance is one of the most critical. This is the case with Ethiopia and in particular in Addis Ababa City Administration. The research objectives include the examination of the factors affecting access to long-term housing finance in Addis Ababa. The study also examines major policy and practical challenges facing the housing development projects in accessing long-term housing project finance. The methodology employed by the research includes the collection of primary and secondary data. In-depth interview was made with senior government officials from the National Bureau of IHDP, and bureau of the Addis Ababa City Administration Office of the IHDP. Interview was conducted with 5 real estate developers, and 11 individual residential house builders. Interview was also conducted with loan officers from 2 CBE, 2 CBB, and 5 private banks. Data obtained were analyzed through transcribing the interview results. Among major findings of the research include the following: that all banks in Ethiopia are highly engaged in the provision of loans for working capital requirements and trade facilitation services, finance for the housing project is given minimal attention, insufficient amount of fund set aside for housing project, CBE is highly engaged in the provision of long-term finance for public projects leaving housing projects insufficiently attended, and private banks complain about the directive of the National Bank of Ethiopia requiring them to purchase government bond for 27% of any outstanding loan they issue. The study suggests that the government housing finance policy should be reviewed and that facilitates the development of housing for all income groups of citizens. In addition, banks should be empowered in facilitating long term finance for access by key players in the sector.

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The vector-tensor (VT) theory of gravitation revisited in this article was studied in previous papers, where it was proved that VT works and deserves attention. New observational data and numerical codes have motivated further development which is presented here. New research has been planed with the essential aim of proving that current cosmological observations, including Planck data, baryon acoustic oscillations (BAO), and so on, may be explained with VT, a theory which accounts for a kind of dark energy which has the same equation of state as vacuum. New versions of the codes CAMB and COSMOMC have been designed for applications to VT, and the resulting versions have been used to get the cosmological parameters of the VT model at suitable confidence levels. The parameters to be estimated are the same as ingeneral relativity (GR), plus a new parameter $D$. For $D=0$, VT linear cosmological perturbations reduces to those of GR, but the VT background may explain dark energy. The fits between observations and VT predictions lead to non vanishing $|D|$ upper limits at the $1σ$ confidence level. The value $D=0$ is admissible at this level, but this value is not that of the best fit in any case. Results strongly suggest that VT may explain current observations, at least, as well as GR; with the advantage that, as it is proved in this paper, VT has an additional parameter which facilitates adjustments to current observational data.}

description: In this note, using the colour string model, we study the configuration space distribution of stopped nucleons in heavy-ion collisions. We find that the stopped nucleons from the target and the projectile end up separated from each other by the distance increasing with the collision energy. In consequence, for the center of mass energies larger than 6 or 10 GeV (depending on the details of the model) it appears that the system created is not in thermal and chemical equilibrium, and the net baryon density reached is likely not much higher than that already present in the colliding nuclei.

Organizations' Recruitment Practice and Persons with Disability (Study Conducted in Addis Ababa)
Creators: name: Asfaw, Tolera
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The study is designed to investigate the practice of recruiting persons with disabilities in organizations. On the other hand, it tried to address how organizations are open for Persons with Disability. Though Organizations know diversity, it is less likely that they understood in terms of hiring and retaining PwDs. This in turn affects the employment opportunity of PwDs. Given these conditions, no research attempted to analyze the recruitment practice of Person with Disability from Organizations side. For this particular research quantitative method was employed. Primary data was collected through questionnaire and interview. The sources for data were organizations recruitment committee, HR manager or HRD worker, qualified person with disability and DPOs. As a source of secondary data proclamations on the right to employment of PwDs, convention on the rights of disability, abstracts and books were used. In conducting the study, both governmental and private organizations were randomly selected in Addis Ababa city to see their recruitment practice especially for PwDs. The other target groups are qualified persons with some form of disability in which structured interview was conducted to collect data from. In addition to this well structured questionnaire was also produced and distributed to both recruitment committees of organizations or human resource department workers and disability people organizations or activists. The descriptive analysis method was employed using percentages, mean and modes. In addition to this, correlation analysis has been used to see the relationship between the variables. The result of the study shows that even though there is recruitment policy in most of organizations the practice aspect needs to be emphasized. The recruitment strategies used by most of organizations are not diversified to attract sufficient pool of applicants, especially PwDs. To reduce problems of recruiting and hiring PwDs; Government, Employers, and DPO's primarily shoulder the responsibilities. Key words; Disability, Recruitment Practice

Blind quantum computation with noise environment
Creators: name: Sheng, Yu-Bo
name: Zhou, Lan
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Blind quantum computation (BQC) is a new type of quantum computation model. BQC allows a client (Alice) who does not have enough sophisticated technology and knowledge to perform universal quantum computation and resorts a remote quantum computation server (Bob) to delegate universal quantum computation. During the computation, Bob cannot know Alice's inputs, algorithm and outputs. In single-server BQC protocol, it requires Alice to prepare and distribute single-photon states to Bob. Unfortunately, the distributed single photons will suffer from noise, which not only makes the single-photon state decoherence, but also makes it loss. In this protocol, we describe an anti-noise BQC protocol, which combined the ideas of faithful distribution of single-photon state in collective noise, the feasible quantum nondemolition measurement and Broadbent-Fitzsimons-Kashefi (BFK) protocol. This protocol has several advantages. First, Alice does not require any auxiliary resources, which reduces the client's economic cost. Second, this protocol not only can protect the state from the collective noise, but also can distill the single photon from photon loss. Third, the noise setup in Bob is based on the linear optics, and it is also feasible in experiment. This anti-noise BQC may show that it is possible to perform the BQC protocol in a noisy environment.

description: The so called one-parameter (often called $\varkappa$) deformed $AdS$ string sigma models have attracted a lot of attention lately in the study of integrability in string theory. We construct various circular string solutions in the $(AdS_3 \times S^3)_{\varkappa}$ background and describe the characteristics of such solutions qualitatively. We study the Bohr-Sommerfeld like quantization for these string states to characterise the motion. Further we find a `long' string limit of such circular strings in the $\varkappa$-deformed $AdS_3$ and find a novel dependence of the oscillation number on the energy in the next to leading order expansion.

"Dividend Policy and Share Prices" (The Case of Private Banks in Ethiopia)
Creators: name: Teame, Berhane
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Effort was made to see any association between dividends and share prices by observing six private banks in Ethiopia. Data was taken for six years (2005 – 2010 G.C.) and descriptive statistics employed with the objective of examining the presumed association between dividends and share prices. The dividend discount model was used to calculate ideal share prices at the banks. The results show there is a strong association between the crude measures of dividends and share prices. Earnings per Share are also strongly correlated with share prices. The Pearson's moment correlation coefficients are statistically significant at 95% confidence level. However, evidence did not support the association between the real measures of dividends and share prices. Also, the actual share prices are a bit higher than model determined share prices for all the six banks. With much decision regarding the dividends and share premiums left to the general meetings of shareholders', it is not clear whether dividends or EPS or other variables determines the share prices of Ethiopian private banks.

description: The radio technique is a promising method for detection of cosmic-ray air showers of energies around $100\,$PeV and higher with an array of radio antennas. Since the amplitude of the radio signal can be measured absolutely and increases with the shower energy, radio measurements can be used to determine the air-shower energy on an absolute scale. We show that calibrated measurements of radio detectors operated in coincidence with host experiments measuring air showers based on other techniques can be used for comparing the energy scales of these host experiments. Using two approaches, first via direct amplitude measurements, and second via comparison of measurements with air shower simulations, we compare the energy scales of the air-shower experiments Tunka-133 and KASCADE-Grande, using their radio extensions, Tunka-Rex and LOPES, respectively. Due to the consistent amplitude calibration for Tunka-Rex and LOPES achieved by using the same reference source, this comparison reaches an accuracy of approximately $10\,\%$ - limited by some shortcomings of LOPES, which was a prototype experiment for the digital radio technique for air showers. In particular we show that the energy scales of cosmic-ray measurements by the independently calibrated experiments KASCADE-Grande and Tunka-133 are consistent with each other on this level.

description: Diese Master Thesis trägt den Titel „Das Sicherungssystem im BTVG und dessen Schwächen“. Das Kernstück der Arbeit bilden die im Bauträgervertragsgesetz (BTVG) normierten Sicherungsinstrumente. Das Gesetz sieht vor, dass allfällige Rückforderungsansprüche des Erwerbers schuldrechtlich und pfandrechtlich (kaum praxisrelevant) gesichert werden können. Ferner kann der Erwerb von Eigentum, Wohnungseigentum oder eines Baurechts auch durch ausreichende grundbücherliche Sicherstellung verbunden mit einer Zahlung nach Ratenplan gesichert werden. Hierbei soll die grundbücherliche Sicherstellung stets das wirtschaftliche Gleichgewicht zwischen den durch den Erwerber geleisteten Zahlungen und den Rechten an der Liegenschaft bzw den Bauleistungen herstellen. Folglich dient dieses Sicherungsmodell lediglich der Sicherung des Rechtserwerbs an der Liegenschaft bzw am Liegenschaftsanteil. Anschließend werden die Schwächen der einzelnen Sicherungsmodelle näher beleuchtet und ein Fazit gezogen.

description: In any country, banking sector plays a vital role for overall development of primary and industrial sectors. The employees in banking company take painful effort to deliver the multiple needs of its customers. Banking industry is still emerging industry in our country; the entry of private banks laid foundation stone and passed a mile journey from its start. This present study attempted to test the relationship between quality of work life and organizational commitment of employees in Commercial Bank of Ethiopia. The research is cross-sectional field survey and co relational study. Among a total of around 3116 employees currently working in CBE in Addis Ababa City, 240 employees were selected as the sample of the study. The standardized questions of Walton (1974) QWL and OC of Meyer et al. (1990) were adapted to undertake the study. Questionnaires were distributed to 240 employees but, 200 respondents filled and replied were found valid for analysis. Spearman correlation and Ordinal logistic Regression was used to analyze the gathered data. The results of the study indicate that QWL has a significant effect on organizational commitment of employees in CBE. Work and the total life space and the social relevance of work life among the five dimensions of QWL have not significant effect on OC of employees. Based on the regression result, it can be concluded that 98.9% of the change in OC is explained by QWL in CBE. Key Words: Quality of Work Life, Organizational Commitment, Commercial Bank of Ethiopia

description: Atomic mass and interatomic interaction are the two key quantities that significantly affect the heat conduction carried by phonons. Here, we study the effects of long-range (LR) interatomic interaction and mass-disorder on the phonon transport in a one-dimensional harmonic chain withup to 10^5 atoms. We find that while LR interaction reduces the transmission of low frequency phonons, it enhances the transmission of high frequency phonons by suppressing the localization effects caused by mass disorder. Therefore, long-range interaction is able to boost heat conductance in the high temperature regime or in the large size regime, where the high frequency modes are important.

description: Das Mittelmeer wurde in den letzten Jahren zum sowohl faktischen Ort eines gewaltvollen Migrationsregimes als auch zum Symbol einer Politik des Sterbenlassens. Hans Blumenberg hat in seinen Überlegungen die Seefahrt und genauer den Schiffbruch als grundlegendes Bild des europäischen Denkens unterstrichen, es handle sich um ein „Paradigma einer Daseinsmetapher.“ Die beobachtende Person auf festem Land nimmt so das untergehende Schiff als Grenzverletzung wahr, und ergötzt sich mitunter daran, nicht selbst Teil der Katastrophe zu sein. In Anbetracht gegenwärtiger Grenzregime reflektiert die Arbeit, welche Bedeutung die Rede vom Schiffbruch für die Gegenwart hat und leuchtet vor dem Hintergrund der eigenen Involvierung die Zusammenhänge von Metapher und Wirklichkeit aus. Die zwischen den europäischen und afrikanischen Küsten liegende Ambivalenz wird versucht zu verstehen mit grundlegenden Überlegungen zur nautischen Metaphorik, einem philosophischen Blick auf offene Grenzen und der Betrachtung des Aufbegehrens von Menschen auf See. Das Bild einer vielköpfigen Hydra beschreibt damit sowohl die andauernde Repression staatlicher Migrationspolitik als auch die Widerstandsfähigkeit und Autonomie migrierender Menschen. Der Zusammenhang zwischen der kolonialen Geschichte der Sklav:innenschiffe und des gegenwärtigen rassialisierten Kapitalismus ist evident. Die Arbeit versucht daraus Schlüsse zu ziehen, indem das Beobachten von Schiffbrüchen, oft aus der Luft, in ihrer nekropolitischen Dimension verortet wird und hinterfragt so das europäische Selbstverständnis.
description: In recent years, the Mediterranean has become both a de facto site of a violent migration regime and a symbol of a policy of letting people die. In his reflections, Hans Blumenberg has underlined seafaring, and more precisely shipwrecks, as a fundamental image of European thought, saying it is a „paradigm of a metaphor of existence.“ The person observing on solid land thus perceives the sinking ship as a border violation and sometimes delights in not being part of the catastrophe itself. In view of current border regimes, this work reflects on the significance of the talk of the shipwreck for the present and illuminates the connections between metaphor and reality against the background of one's own involvement. This work seeks to understand the ambivalence lying between the European and African coasts by examining nautical metaphors, exploring the philosophical concept of open borders, and considering the rebellion of people at sea. The image of a many-headed hydra thus depicts both the ongoing repression of state migration policies and the resilience and autonomy of migrating people. The connection between the colonial history of salve ships and contemporary racialized capitalism is evident. This work attempts to draw conclusions from this by locating the observation of shipwrecks, often from the air, in their necropolitical dimension and thus questions the European self-image.

description: The nuclear symmetry energy characterizes the variation of the binding energy as the neutron to proton ratio of a nuclear system is varied. This is one of the most important features of nuclear physics in general, since it is just related to the two component nature of the nuclear systems. As such it is one of the most relevant physical parameters that affect the physics of many phenomena and nuclear processes. This review paper presents a survey of the role and relevance of the nuclear symmetry energy in different fields of research and of the accuracy of its determination from the phenomenology and from the microscopic many-body theory. In recent years, a great interest was devoted not only to the Nuclear Matter symmetry energy at saturation density but also to its whole density dependence, which is an essential ingredient for our understanding of many phenomena. We analyze the nuclear symmetry energy in different realms of nuclear physics and astrophysics. In particular we consider the nuclear symmetry energy in relation to nuclear structure, astrophysics of Neutron Stars and supernovae, and heavy ion collision experiments, trying to elucidate the connections of these different fields on the basis of the symmetry energy peculiarities. The interplay between experimental and observational data and theoretical developments is stressed. The expected future developments and improvements are schematically addressed, together with most demanded experimental and theoretical advances for the next few years.

Assessment of Valuation Methods and Modalities of Divestment used by Privatization and Public Enterprises Supervising Agency (PPESA)

description: Privatization of State Owned Enterprises (SOE) has increasingly become an important phenomenon in both developed and developing countries in the last few decades. Literatures on privatizations in Ethiopia indicate that Privatization and Public Enterprises Supervising Agency (PPESA) has a closed door policy and little is known regarding valuation of the Enterprises to be privatized. The aim of this paper is therefore to fill this gap, assess and increase knowledge on how valuation is being done in Privatization and Public Enterprises Supervising Agency (PPESA).The methodology used is a case study design where the units of enquiry focus on the valuation method and the modalities of divestment. Both primary and secondary data are used; interview of relevant experts in PPESA and data of 316 privatized firms. Relevant books, publications & reports have also been examined. Moreover, the status of privatization is reviewed and trends are analyzed; attempts are also made to examine the variance of this valuation with the final acquisition value. The findings show that PPESA uses both asset valuation & business valuation methods. PPESA has shown effort to use current acceptable methods and tools like Capital Asset Pricing Model (CAPM) during business valuation, but it may be misleading to use it in the absence of a stock exchange and other standards to refer to estimate the different variables in the model. The data also shows that privatization has not attracted FDI as expected; though with limited data and only one variable was used, the valuation of the firms in estimating the market value seems very low. In almost all cases the valuation is much lower than the acquisition price. It is recommended that in order to address challenges with valuation, there is a need for stock exchange both for privatizing the remaining firms with PPESA as well as for making progress in the trade industry in Ethiopia.

description: A sigma-Fe54.5Cr45.5 samples irradiated in vacuum with 2 MeV Fe3+ ions at 300, 400, 475 and 700 deg C to the maximum dose of 12.5 dpa were studied with the conversion electron Mössbauer spectroscopy (CEMS). The analysis of the room temperature CEMS spectra revealed an irradiation-induced redistribution of Fe atoms viz. their number on B and D sites decreased while on A, C and E sites increased. The degree of the redistribution was found to be proportional to the number of Fe atoms present on the lattice sites in the non-irradiated samples. The highest degree of the redistribution was revealed in the sample irradiated at 300 deg C. No change in the site occupancy was found in the sample irradiated at 700 deg C.

description: Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (M$_V = -16.60$, Mass $\sim 4\times10^8$ M$_\odot$), located in the Fornax cluster, have been performed with the VLT/ MUSE spectrograph in the wavelength region from $4750-9350$ Å. In this paper we present a stellar population analysis studying chemical abundances, the star formation history (SFH) and the stellar initial mass function (IMF) as a function of galacto-centric distance. Different, independent ways to analyse the stellar populations result in a luminosity-weighted age of $\sim$ 6 Gyr and a metallicity [Fe/H]$\sim$ $-0.4$, similar to other dEs of similar mass. We find unusually overabundant values of [Ca/Fe] $\sim +0.1$, and under-abundant Sodium, with [Na/Fe] values around $-0.1$, while [Mg/Fe] is overabundant at all radii, increasing from $\sim+0.1$ in the centre to $\sim +0.2$ dex. We notice a significant metallicity and age gradient within this dwarf galaxy. To constrain the stellar IMF of NGC 1396, we find that the IMF of NGC 1396 is consistent with either a Kroupa-like or a top-heavy distribution, while a bottom-heavy IMF is firmly ruled out. An analysis of the abundance ratios, and a comparison with galaxies in the Local Group, shows that the chemical enrichment history of NGC 1396 is similar to the Galactic disc, with an extended star formation history. This would be the case if the galaxy originated from a LMC-sized dwarf galaxy progenitor, which would lose its gas while falling into the Fornax cluster.
