description: Conjugated metallic nanoparticles are a promising means to achieve ultrasensitive and multiplexed sensing in intact three-dimensional samples, especially for biological applications, via surface enhanced Raman scattering (SERS). We show that enhancement and extinction are linked and compete in a collection of metallic nanoparticles. Counterintuitively, the Raman signal vanishes when nanoparticles are excited at their plasmon resonance, while increasing nanoparticle concentrations at off-resonance excitation sometimes leads to decreased signal. We develop an effective medium theory that explains both phenomena. Optimal choices of excitation wavelength, individual particle enhancement factor and concentrations are indicated.

description: Kurz gefasst:

Gestaltungs- und Regelungsvielfalt im Angebot dualer Studiengänge führt in zunehmendem Maße zu Intransparenz, Beliebigkeit und mangelnder Kontrollierbarkeit dieser Studienform.Hieraus ergibt sich die Notwendigkeit zur Entwicklung verbindlicher und bundesweit einheitlich geltender Mindeststandards dualer Studienkonzepte.
Dem Aufbau verbindlicher Gremienstrukturen, wie z.B. die Einrichtung von Beiräten, basierend auf Kooperationsverträgen zwischen allen beteiligten Akteuren, kommt hierbei ein zentraler Stellenwert zu.
Die Entwicklung gemeinsamer Curricula und verbindlicher Studienpläne zur Optimierung der Verknüpfung von Theorie- und Praxisphasen an verschiedenen Lernorten, insbesondere in Abstimmung zwischen Betrieb und Hochschule, ist für die Qualitätssicherung im dualen Studium wesentlich.
Die Situation der Studierenden hinsichtlich vertraglicher Regelungen zur Anerkennung von Lernleistungen, zur Abstimmung von Lerninhalten und -zeiten, sowie betrieblicher Regelungen zu Ausbildungsbedingungen, Übernahme und Weiterqualifizierung muss verbessert werden.

description: The structure of heavy hyperhydrogen $^6_Λ$H is studied within the framework of a $tnnΛ$ four-body cluster model. Interactions among the constituent subunits are determined so as to reproduce reasonably well the observed low-energy properties of the $tn, tΛ$ and $tnn$ subsystems. As long as we reproduce the energy and width of $^5$H within the error bar, the ground state of $^6_Λ$H is obtained as a resonant state.

description: Although the influence of intent understanding on children’s moral development has been long studied, little research has examined the influence of belief understanding on that development. In two studies we presented children with morally relevant belief vignettes to examine the extent to which they incorporate both intent and belief information in their moral judgments. In Study 1 (N = 64), 5-year-olds with higher false belief understanding (FBU) rated agents with false beliefs as more positively intentioned in good intent trials (even though the outcome was bad) than in bad intent trials (even though the outcome was good). In contrast, 4-year-olds with higher FBU were generally unable to integrate their belief understanding with their moral evaluations, performing no better on intention questions than children with lower FBU. Neither age group significantly differentiated reward and punishments as a function of intent when a false belief was involved. In Study 2 (N = 109 children, N = 42 adults), we found that by simplifying our study design and reducing the task demands, 4-year-olds with higher FBU were able to make appropriate intent judgments. Yet, as in Study 1, all children had difficulty assigning punishment/ reward based on intent. For both moral intentions and moral consequences, 4 and 5-year-olds with higher FBU differed from those of adults in several respects, indicating that moral reasoning develops substantially beyond the preschool years.

description: An astrophysical population of supermassive black hole binaries is thought to be the strongest source of gravitational waves in the frequency range covered by Pulsar Timing Arrays (PTAs). A potential cause for concern is that the standard cross-correlation method used in PTA data analysis assumes that the signals are isotropically distributed and Gaussian random, while the signals from a black hole population are likely to be anisotropic and deterministic. Here we argue that while the conventional analysis is not optimal, it is not hopeless either, as the standard Hellings-Downs correlation curve turns out to hold for point sources, and the small effective number of signal samples blurs the distinction between Gaussian and deterministic signals. Possible improvements to the standard cross-correlation analysis that account for the anisotropy of the signal are discussed.

description: In digital transformation, incumbents are pressured to exploit their core business and simultaneously explore opportunities for digital innovation. When pursuing ambidexterity, organizations establish digital innovation units (DIUs) dedicated to digital innovation. Due to the novelty of the phenomenon, prior studies targeted DIUs' design, objectives, and challenges. However, their value lies in reintegrating digital innovations back into the operational organization for use and commercialization, which has been neglected so far. Thus, we analyze the reintegration based on a single-embedded case study of four heterogeneous DIUs. We identify three phases of reintegration activities and trace differences to the contextual factors: innovation orientation, number of involved entities, and ownership. Our contribution is twofold. First, we shed light on the reintegration of DIUs' innovation outcomes for the first time. Second, we extend research on digital innovation and ambidexterity by outlining drivers and inhibitors of reintegration, enhancing our understanding of how organizations can exploit exploration.

description: We study a model for the observed phenomenon of electron spin resonance (ESR) at the Zeeman frequency as seen by a scanning tunneling microscope (STM) via its current noise. The model for this ESR-STM phenomenon allows the STM current to flow in two arms of a nanoscopic interferometer, one arm has direct tunneling from the tip to the substrate while the second arm has tunneling through two spin states. We evaluate analytically the noise spectrum for non-polarized leads, as relevant to the experimental setup. We show that spin-orbit interactions allow for an interference of two tunneling paths resulting in a resonance effect.

description: The random-phase approximation (RPA) is here applied to a two-orbital model for the BiS2-based superconductors that was recently proposed by Usui et al., arXiv:1207.3888. Varying the density of doped electrons per Bi site, n, in the range 0.46 < n < 1.0, the spin fluctuations promote competing A1g and B2g superconducting states with similar pairing strengths, in analogy with the A1g-B1g near degeneracy found also within RPA in models for pnictides. At these band fillings, two hole-pockets centered at (0,0) and (π,π) display nearly parallel Fermi Surface segments close to wavevector(π/2,π/2), whose distance increases with n. After introducing electronic interactions treated in the RPA, the inter-pocket nesting of these segments leads to pair scattering with a rather "local" character in k-space. The similarity between the A1g and B2g channels observed here should manifest in experiments on BiS2-based superconductors if the pairing is caused by spin fluctuations.

description: Soil and water losses and nutrient depletion are major limiting factors for crop growth and yield. Smallholder farmers need to invest in combined-use of structural, vegetative, and agronomic practices in an attempt to close the yield gap. This study aimed to evaluate the impacts of combineduse of soil conservation practices in maximizing crop yield and household income in the sub-humid highland of Ethiopia using farmer estimation techniques at the field level. Grain yield and household income data were generated through conducting face-to-face interviews with 150 farm household heads selected using a systematic random sampling technique. The data were analyzed using independent t-test, and analysis of variance. The mean grain yields from fields treated with combineduse soil conservation practices increased by 40.18% for tef and 50.37% for the wheat crop, and significantly higher at f=69.8 and p<0.01 for tef, and f=35.3 and p<0.01 for wheat, compared to fields treated with common traditional practices. The size of irrigated croplands (in ha), beehive numbers and livestock sizes were positively and significantly (at p<0.01) associated with the increase of households' income. The total size of farmlands and trees planted field (in ha) were also positively and significantly (at p<0.05) related to the improvement of individual household income. Therefore, efforts should be made to boost crop productivity through scaling-up of combined-use of vegetative stabilized structure practices and compost under the legume-cereal crop farming system. There need to be enhanced forage, livestock and tree production, and plantation of legume and flowering plants on uncultivated privately owned plots for apiculture production.

description: Sensitive high angular resolution ($\sim$ 2$"$) CO(2-1) line observations made with the Submillimeter Array (SMA) of the flow emanating from the high-mass star forming region DR21 located in the Cygnus X molecular cloud are presented. These new interferometric observations indicate that this well known enigmatic outflow appears to have been produced by an explosive event that took place about 10,000 years ago, and that might be related with the disintegration of a massive stellar system, as the one that occurred in Orion BN/KL 500 years ago, but about 20 times more energetic. This result therefore argues in favor of the idea that the disintegration of young stellar systems perhaps is a frequent phenomenon present during the formation of the massive stars. However, many more theoretical and observational studies are still needed to confirm our hypothesis.

description: Developing irrigation agriculture is a means of increasing food production and of improving the livelihood of smallholder farmers dwelling in areas with very erratic and unpredictable weather conditions. Therefore, this study aimed to analyze the determinants of small irrigation practices and their contribution to household farm income in the Geray irrigation scheme in Northwest Ethiopia. A simple random sampling technique was employed for the selection of 231sample households. Data was collected from 171 irrigation users and 60 non-users. A structured household survey questionnaire, key informant interview, and focus group discussion were employed to collect primary data. Descriptive and inferential statistics were employed to estimate determinants of small-scale irrigation practice and household income. The study revealed that practicing in small-scale irrigation has played a significant role in increasing the total income of households in the study area. The study showed that practicing irrigation schemes has a positive impact on crop production. The binary logistic regression results also revealed that practicing irrigation is determined by the total income of households, livestock ownership age, family size, training, marital status, size of irrigable land, and access to market information. Therefore, to improve irrigation practices by smallholder farmers, local governments and other concerned bodies should attempt to address those factors that can affect small-scale irrigation practices in the study area.

description: This thesis explores the use of lipid nanoparticles called bicontinuous cubic phases for biomedical applications, including drug delivery systems and biosensors. These lipidic cubic phases have shown great potential in encapsulating therapeutic proteins and peptides, but it is still not understood how they influence the structure and function of these therapeutic molecules. Overall, the thesis creates a library of fusion peptide - lipid nanoparticle combinations suitable for encapsulating various therapeutics. It sheds light on how the lipid composition and curvature of nanoparticles affect fusion peptide behaviour, which is critical for developing better drug delivery systems. The work also proposes viral inactivators targeting key proteins and lipid regulation to combat non-enveloped viruses. The findings have significant implications for enhancing peptide-lipid nanomaterial treatment solutions in vitro and understanding nanoparticle-cell membrane interactions.

description: Micro-domains of modified surface potential (SP) were created on hydroxyapatite (HAp) films by direct patterning by midenergy focused electron beam, typically available as a microprobe of Scanning Electron Microscopes. The SP distribution of these patterns has been studied on sub-micrometer scale by the Kelvin Probe Force Microscopy method as well as lysozyme adsorption. Since the lysozyme is positively charged at physiological pH, it allows us to track positively and negatively charged areas of the SP patterns. Distribution of the adsorbed proteins over the domains was in good agreement with the observed SP patterns.

description: Following a recent rapid communications[Phys.Rev.C85,021302(R) (2012)], we present more details on the investigation of the relativistic symmetry by use of the similarity renormalization group. By comparing the contributions of the different components in the diagonal Dirac Hamiltonian to the pseudospin splitting, we have found that two components of the dynamical term make similar influence on the pseudospin symmetry. The same case also appears in the spin-orbit interactions. Further, we have checked the influences of every term on the pseudospin splitting and their correlations with the potential parameters for all the available pseudospin partners. The result shows that the spin-orbit interactions always play a role in favor of the pseudospin symmetry, and whether the pseudospin symmetry is improved or destroyed by the dynamical term relating the shape of the potential as well as the quantum numbers of the state. The cause why the pseudospin symmetry becomes better for the levels closer to the continuum is disclosed.

description: Development agents (DAs) are assigned in the local administrations called Kebeles to provide training/advising services to smallholder farmers. In this contribution, the participation of women farmers is compared with that of male farmers in the context of Ankasha district, Awi Zone, Ethiopia. Annual reports on number of trainees were accessed from the district department of Agriculture (2011-2014). Basically, reviewing district reports was done followed by interviewing experts (N=9), DAs (N=6), and organizing 3 Focus Group Discussions with farmers (N=31) each composed of 10-11 individuals. All experts, DAs, and farmers were selected purposively. The Focus Group Discussions were organized in three Kebeles which were selected using lottery method of simple random sampling from 33 Kebeles in the district. To prioritize factors that contributed to low participation of women farmers and to get participant farmers' perceptions, the study used Likert scale type of questionnaire. The results revealed that illiteracy, poor mainstreaming of gender in the agricultural sector and priority to widowed or divorced women farmers as the first, second, and third (respectively) important factors to contribute to low participation of women farmers in the training services provided by the district. Thus, largely, women farmers' participation was found nominal. The extension training and advising services provided by DAs have to consider all women farmers (widowed, divorced, married, and bachelorettes). In the study context, women of all social status are participating in the farming activities of pre-planting, during-planting, and after-planting. And, there is a need to design a training programme in line with these activities for women farmers of all social status. The study will have theoretical contribution to adult learning theory and gender development or mainstreaming. This is the first study to evaluate district level training services as related to the number of women farmer participants in the public agriculture-related education programmes.

description: This study examined the variations in soil properties, and carbon and nutrient storages under different land use types in the flood plains of Metehara, upper part of the Main Ethiopian Rift Valley. The study considered four land use types: cane plantation (CP), free grazing lands (FG), traditional maize farming (MF), and restored pasture (RP). The study established four transects with typical land use types and selected three soil sampling sites with 50m intervals from the upper-slope and the lower-slope position under each land use type. In each slope position, a 10m x 10m plot was established to collect the soil samples. A total of 24 distributed soil samples (3 land uses, and 3 replications) from 0 to 30 cm depth were collected using soil auger. The results indicate that the land use types significantly affected the soil parameters (P<0.001) whereas the slope position did not. The land use type explained the variations in soil carbon (R2 =0.77, P<0.001, df = 23), and total nitrogen (R2 =0.39, P<0.05). However, the results indicate insignificant effects on soil carbon and nitrogen variations when combining the soil properties covariate with land use factor in statistical model than the variation explained by land use type. The result also reveals that soil carbon (C) and total nitrogen (N) contents under the RP were significantly higher than the FG and MF sites. This study generally suggests how land use change has increasingly affected the semi-arid ecosystems and highlights the need to improve awareness about how human land use and land management decision impacts in the semi- arid areas of Ethiopian Rift Valley.

title: Learning by watching tutorial videos: impacts of dialogue and collaboration
Creators: name: Chen, Xingbang

Year: 2023

description: We are in a digital age when thousands of tutorial videos are available online. These videos are popular learning sources. However, we still know little about what makes a video powerful, and how to learn better by watching videos. A few studies show that observers learn better when collaboratively watching dialogue videos (recordings of conversations between a tutor and a tutee). However, the superiority of dialogue videos over monologue videos (recordings of a tutor’s monologues) was not consistently shown in the literature. In addition, the advantage of collaboration over solo appeared only when observers watched dialogue videos. Those studies were limited to college student populations in English-speaking countries. The current study used a two-way between-subject design with pre- to posttest measures. It compared the learning outcomes of 60 students who watched tutorial dialogue and monologue videos alone and in pairs at a junior high school in China. Findings show that observers watching the dialogue video in pairs presented the most considerable learning effect and motivation. The results revealed a strong interaction effect between the dialogue video and collaboration. That is, only collaborative observers learned more from the dialogue video than from the monologue, and collaborative observers outperformed solo observers exclusively in dialogue observation.
The Diversion of Abbay/ Nile by Ethiopian Emperors: Claims and Disclaims
Creators: name: Bayu, Yeshambel Kindie

Year: 2020

description: After Egypt occupied by the Arabs in 641, the relationship between Christian Ethiopia and Muslim Egypt was quarrelsome. Successive Muslim leaders of Egypt continue to convert Christians forcefully and this kind of maltreatment against Copts worsens the relationship between the two countries. In retaliation, Ethiopian Emperors took different measures against Muslim leaders. Sometimes they have invaded Upper Egypt and at another time diverted the course of Abbay so as to compel Egyptian Sultans with their request. Accordingly, Egyptians had been encountered a terrible famine because of the diversion of Abbay, to mention some, from 963 to 969, 1066 to 1072 and, 1199 to 1202. Regrettably, however, the ability of Ethiopian Emperors to divert the course of Abbay in order to stop the persecution of Copts considered as a myth. This paper attempted to examine medieval sources of Egypt and Ethiopia and offers substantial evidence as Abbay was diverted by Ethiopian Emperors.

Like the Pareto and the lognormal distributions it was originally proposed for modeling economic size distributions, notably the size distribution of personal income. This paper explores a probabilistic property of the Benini distribution, showing that it is not determined by the sequence of its moments although all the moments are finite. It also provides explicit examples of distributions possessing the same set of moments. Related distributions are briefly explored.

description: Attractiveness is a concept long studied by psychologists, and of interest to many lay people, as it influences our perception of others. Two evolutionary principles, sexual dimorphism and facial contrast, drove this research to explore the effects of attractiveness from the perception of both young and older adults. Many features of the face have been studied before, such as eyes and lips, but this research seeks to understand the importance of eyebrows on attractiveness. In this study, different conditions of eyebrows were manipulated to enhance certain features, such as the thickness, thinness, darkness, and lightness of the eyebrows. Both young adult (college students) and older adults were asked to participate in this study. Participants were shown 100 images and then asked to rate how attractive they perceived each face. Young adults rated the lighter eyebrow conditions as less attractive, consistent with theories of sexual dimorphism. Older adults preferred thicker eyebrows, which was inconsistent with the hypothesis. Overall, both the young and older adults rated the original eyebrow condition as more attractive, indicating a preference for more naturally looking eyebrows. Results were closely supported by the current trends of eyebrows and exemplifies the significance of current trends and cultural differences on perceived attractiveness in society.

A small fraction of extremely metal-poor (EMP) stars exhibit excesses of heavy neutron-capture elements produced in the r-process, and CS 31082-001 is among the 4 well-known r-process-enhanced EMP stars. Observations with HST/STIS provide abundances for elements observable only from the UV region. Here we aim to supplement the optical data with abundances from near-UV spectroscopy of the first and second peak of the r-elements, which are crucial to giving insight into the nucleosynthesis of the elements beyond iron. The UVES spectrum provided additional measurements, thereby improving the previous results. The spectra were analyzed with the OSMARCS LTE model atmosphere and with a consistent approach based on the spectrum synthesis code Turbospectrum to derive abundances of heavy elements in CS 31082-001, using updated oscillator strengths from the recent literature. We computed synthetic spectra for all lines of the elements of interest, checking for proper intensities and possible blends. We combined the abundances of heavy elements derived in previous works with the derivation of abundances from all reliable new list of lines, for the first and second peaks of r-elements. We were able to derive new abundances for 23 n-elements, 6 of them - Ge, Mo, Lu, Ta, W, and Re - were not available in previous works, making this star the most complete r-II object studied, with a total of 37 detections of n-capture elements. We also present the first NLTE+3D lead abundance in this star. The results provide improved constraints on the nature of the r-process.

description: The social recommender system that supports the creation of new relations between users in the multimedia sharing system is presented in the paper. To generate suggestions the new concept of the multirelational social network was introduced. It covers both direct as well as object-based relationships that reflect social and semantic links between users. The main goal of the new method is to create the personalized suggestions that are continuously adapted to users' needs depending on the personal weights assigned to each layer from the social network. The conducted experiments confirmed the usefulness of the proposed model.

description: Prior research has shown that non-suicidal self-injury (NSSI) is maintained by negative emotional reinforcement. Due to barriers and stressors the gender diverse community faces, such as limited access to gender affirming healthcare and discrimination from the general and queer community, engagement in ineffective coping mechanisms is common. Lack of access to effective treatment can lead to these ineffective behaviors being a main source of comfort and potentially becoming an addictive behavior. The current study explores how experienced stigma as a gender diverse individual affects frequency of engagement in NSSI. Difference in cravings levels between individuals actively engaging in NSSI and individuals in recovery are investigated to assess whether there is a difference in cravings when accounting for recovery status. Correlations between experienced stigma and frequency of engagement in NSSI indicate that certain types of experienced stigma correlate with an increased frequency of engagement in NSSI. When assessing for cravings between those actively engaging in NSSI and those who formerly engaged in NSSI, it was found that cravings tend to occur at a higher frequency for the active group. Consistent with prior research, NSSI engagement was found to occur in higher frequency when interpersonal conflicts related to stigma were experienced. It can be concluded that cravings were significantly higher in the active NSSI engagement group. The potential for NSSI to be considered an addictive behavior warrants further research.

Form factors for semileptonic D decays

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the form factors for semileptonic decays of $D$-mesons. That is, we consider the matrix element of the weak left-handed quark current for the transitions $D \rightarrow P$ and $D \rightarrow V$, where $P$ and $V$ are light pseudoscalar or vector mesons, respectively. Our motivation to perform the present study of these form factors are future calculations of non-leptonic decay amplitudes. We consider the form factors within a class of chiral quark models. Especially, we study how the Large Energy Effective Theory (LEET) limit works for $D$-meson decays. Compared to previous work we also introduce light vector mesons $V = ρ, K^*,...$ within chiral quark models. In order to determine some of the parameters in our model, we use existing data and results based on some other methods like lattice calculations, light-cone sum rules, and heavy-light chiral perturbation theory. We also obtain some predictions within our framework.

description: Smallholder irrigation has enormous potential to improve the incomes of poor rural households in developing countries like Ethiopia. However, numerous problems constrain irrigated crop production and irrigation water management efforts in many areas. In light of this, a survey was conducted with the objective of assessing the challenges of irrigation water management over smallholder schemes, in Dembecha Woreda (District), in the northwestern highlands of Ethiopia. Data were gathered through key informant interviews, group discussions, field observations and a questionnaire survey of 118 households. The data gathered were then analyzed using descriptive statistics; independent sample T-test and the Chi-square test. The results showed that irrigation water in the study area was distributed using rotation turns and the process was managed by an elected body of water users called irrigation water use committees. Over 63% of the respondents faced water shortages on their farms. Loss of water through seepage, poor coordination of water distribution by water use committees, water theft problems, water shortage at tail-end irrigators, absence of enforcing rules, water use conflicts, and rotation turn abuses were identified as major challenges of irrigation water management in the study areas. Hence, it is suggested that farmers be encouraged to harvest rain and underground water to stabilize water shortages and be provided with water management trainings.

description: he objective of the study is to reconstruct the history of Derbé Belanbel historical and cultural site. Methodologically the researcher mainly used the qualitative method and culled data from secondary literature but the study heavily relies on field observation and information gathered from knowledgeable informants. As far as I have tried to establish, Derbé Belanbel was a medieval center of culture and civilization of the Harla Somalis characterized by stone built houses, steles, and a Mosque that appropriately suggest a religious settlement. The stone built houses are similar with those located in the Harar, Dire Dawa and Zeila areas as well as with those located in the northern parts of proper Somalia. Though differences in the softness and hardness of the surfaces of the materials used in their productions and the artistic elements we see in them, many of the steles found at Derbé Belanbel display interesting geometric similarity with the Ţiya steles located in the Guraghe Zone of southern Ethiopia. Fragments of pottery, grains of beads, and fragments of glasses that we recovered from the very site suggest the people were skilled in the preparation of household materials from clay soil and had established commercial link as far as the port of Zeila in the northwest and Mogadishu in the east. Overall, though the site is found in a precarious condition owing to lack of attention by the concerned bodies, Derbé Belanbel represented a medieval culture of greater importance, which would immensely contribute to the history of the Ethiopian Somalis and for the growth of the tourism industry of the Regional State. Depending on the effort of the Regional State, the site could be registered in UNESCO as world heritage site.

description: Soil erosion is a widespread problem on cultivated fields in northwest Ethiopia. Plot level survey studies of soil erosion and conservation are few and far fewer have involved farmers in their assessments of the erosion process and farmers‘ conservation efforts. This paper presents the outcome of a farmer-participatory research conducted at two rural communities, Dubi and Gayta, in Dangila woreda (district), in the northwestern highlands of Ethiopia. The study estimated the extent of soil erosion from tree root exposure measurements and identified farmers‘ soil and water conservation (SWC) practices by categorizing the farmers into three income groups: poor, medium and rich households. Data were collected from 31 plots between May and October 2010. Descriptive statistics and analysis of variance (ANOVA) were used to analyze the data. The results indicate that average rates of soil erosion to be about 1.26 mm yr -1 , but rates varied from 1.94 mm yr on seriously affected sites to 0.21 mm yr -1 on the relatively less affected areas. The farmers used contour farming, traditional ditches, grass and tree planting for SWC purposes. The study concludes that as the extent of soil erosion is highly variable spatially, plot and location specific SWC measures that are designed by considering farmers‘ indigenous knowledge will be required to control soil loss in the study area. This study demonstrates that participatory plot level tree root exposure assessment provides useful information for soil and water conservation planning.
