Acquiring Advanced Technologies & Digitalization – Does Acquirer Experience Count?

This study aims to determine whether acquirer shareholders in nontech sectors perceive acquisitions of high-tech targets as value-creating. The topic is motivated by the rapid development of advanced and digital technologies that has fuelled techrelated M&A volumes. Firms in traditional sectors have become the main acquirers in this field, using tech targets to substitute or complement their own R&D and to stay competitive in the era of digital revolution. Also, the study examines the role of acquirer experience in these takeovers. It contributes to the existing research as the first one focusing on tech-oriented takeovers in the 2010s, from the perspective of a European acquirer. In addition, high-tech keywords were used for the first time in an academic context when sampling relevant takeovers with a digital orientation. The empirical part is divided into an event study and a multiple regression analysis, with a dataset consisting of 1146 high-tech oriented deals announced by European acquirers during the period of 2006-2019. The results revealed the acquirer investors to be clearly optimistic about the announcements of tech-oriented takeovers, with positive and significant two-day cumulative abnormal returns of 0,82%. The finding is economically significant and has a clear contribution: it highlights the perceived relevance of M&A as a part of traditional firms’ digitalization strategies. As another interesting finding, industrial acquirers seemed to gain substantially. Finally, onetime buyers were found to experience significantly higher cumulative abnormal returns than frequent buyers, and frequent buyers to exhibit a weak declining return pattern in subsequent deals. This implies that companies get rewarded for acquiring digital technology, and especially so in their first initiative to digitalize the business.
1 Integrable systems : Yang-Baxter equation , Bethe ansatz , Yangian , Lax Pairs , Toda and Calogero-Moser systems ; application to

A hamiltonian mechanical system (i.e. in 0+1 dimensions) with n degrees of freedom is integrable if it has n independent integrals of motion, in which case it is completely solvable. A 1+1 dimensional field theory is integrable if it is solvable by means of the quantum inverse scattering method (derive S matrices through equations imposed on it, and then derive everything from them). It also has an infinite number of conserved quantities (“integrals of motion”), that can sometimes be used to map the system to an infinite dimensional integrable hamiltonian mechanical system. The best known example is the sine-Gordon theory, for a scalar field with equation of motion
Trade Credit, Debt Finance Structure and SMEs Growth in Rwanda

This study examined the influence of trade credit and debt finance structure on the growth of SMEs in Rwanda guided by two specific objectives; to investigate the influence of trade credit finance structure on the growth of small and medium manufacturing enterprises in Rwanda and to evaluate the influence of debt finance structure on the growth of small and medium manufacturing enterprises in Rwanda. The study used mixed research design for collecting, analyzing and integrating data using a target population of all the 868 small and medium manufacturing enterprises registered with Rwanda Development Board. Stratified random sampling technique was used to draw a sample size of 273 SMEs. Close-ended questionnaires were used in data collection and data was analyzed by way of Statistical Package for Social Science (SPSS) to generate descriptive statistics. Multiple regression analysis was used to explore the relationship between trade credit, debt finance and growth of small and medium size manufacturing enterprises in Rwanda. Analysis of variance (ANOVA) was utilized to test the significance of the model. Results of R2 indicted the goodness fit of the regression model. Study findings show that trade credit finance structure has a positive and significant effect on growth of small and medium manufacturing enterprise in Rwanda while results on debt finance structure were found to be insignificant. Based on these findings, the study recommends that stakeholders should ensure availability of various financing options for SMEs in Rwanda.
The Global Sleep Crisis and University Education: Counseling Implications for Mathematics Education Students in Nigeria

Sleep has been considered a vital component of mental, physical and academic well-being of higher education students. This study adopts the survey research design to investigate the pattern of some sleep variables among mathematics education students in North Central Nigeria. The sample comprises 215 mathematics education students randomly drawn from two federal universities in North Central Nigeria. The instrument for data collection is the researcher-developed Technology Usage and Sleep Pattern Questionnaire (TUSPQ). Data collected on use of electronic device at bedtime, screen time during daytime, sleep onset latency (SOL), wake after sleep onset (WASO), subjective sleep need (SSN), nighttime phone location and nighttime awakenings were analyzed using frequency counts, simple percentages and means. The results indicate dismal sleep duration of 5 hours and 19 minutes and a sleep deficit of 2 hours and 35 minutes attributable to high use of smartphones, laptops and TVs in the last hour before going to bed. The implications of these findings for counseling interventions in Nigeria’s higher education system were considered. Key-words: Sleep, Sleep Deficiency, Sleep Counseling, Mathematics Education, Higher Education.

Mental Health Issues amongst International Students in Australia: Perspectives from Professionals at the Coal-face

The 2011 National Summit on the Mental Health of Tertiary Students draws attention to an increasing incidence of mental health problems amongst this population. Media reports also reflect growing concern over student mental health and adjustment issues. Within this context, we note that Australia is host to many thousands of international students of an age when mental illnesses are most likely to surface. The issue of international student mental health, however, has been the subject of very few Australian studies. We contribute to this area of research by reporting on issues relating to the mental health of international students at an Australian university. Interviews with 16 professionals working at the coal-face provide insights into the factors believed to contribute to the increased incidence and severity of mental health problems encountered by this group of students. We identify three main sets of factors that appear to heighten the stresses and strains experienced by international students: the experience of new and often unfamiliar academic practices, the broad range of knowledge and practical skills needed to manage day-to-day living in Australia, and the tendency to delay professional help-seeking for mental health problems.
Interleaved Multi-Vectorizing

SIMD is an instruction set in mainstream processors, which provides the data level parallelism to accelerate the performance of applications. However, its advantages diminish when applications suffer from heavy cache misses. To eliminate cache misses in SIMD vectorization, we present interleaved multi-vectorizing (IMV) in this paper. It interleaves multiple execution instances of vectorized code to hide memory access latency with more computation. We also propose residual vectorized states to solve the control flow divergence in vectorization. IMV can make full use of the data parallelism in SIMD and the memory level parallelism through prefetching. It reduces cache misses, branch misses and computation overhead to significantly speed up the performance of pointer-chasing applications, and it can be applied to executing entire query pipelines. As experimental results show, IMV achieves up to 4.23X and 3.17X better performance compared with the pure scalar implementation and the pure SIMD vectorization, respectively.
Observability, redundancy and modality for dynamical symmetry transformations

I provide a fairly systematic analysis of when quantities that are variant under a dynamical symmetry transformation should be regarded as unobservable, or redundant, or unreal; of when models related by a dynamical symmetry transformation represent the same state of affairs; and of when mathematical structure that is variant under a dynamical symmetry transformation should be regarded as surplus. In most of these cases the answer is `it depends': depends, that is, on the details of the symmetry in question. A central feature of the analysis is that in order to draw any of these conclusions for a dynamical symmetry it needs to be understood in terms of its possible extensions to other physical systems, in particular to measurement devices.
Wheelchair Accessibility of Tourists Sites in Kuwait: A Descriptive Study

Accessibility refers to a minimum level of design and built-in environment necessary to accommodate people with disabilities [1]. Environmental accessibility is a basic right of any member in the society because it is a major factor that can directly influence one’s engagement and participation in the community. From the occupational therapy perspective, engagement and participation in community is considered an ultimate goal for human beings and has a great influence on health and wellbeing [2]. According to Occupational Therapy Practice Framework: Domain and Process, engagement in occupations are central meaning to individuals and groups [2].
Factors Affecting Health Seeking Behaviors Among Mothers of Under Five Children Attending Primary Health Care Centers, Sudan

Children represent the most vulnerable age group in any community. In Sudan they have higher morbidity and mortality rates. Mothers’ health seeking behaviors are major determinants for improving child health and knowledge about the factors influencing such practice is very crucial for designing effective intervention strategies. This studyaimsto study factors affecting health seeking behaviors for illness in under five children among the mothers in Khartoum state, Sudan. It was Across-sectional study usingbothquantitative and qualitative methods, Four hundreds and ninety five (495) mothers of those who visited the vaccination units of 33 public health centers were interviewed. Four focus group discussions were held. Chi-square test and regression analysis were used to determine the association between different factors and health seeking behaviors. The results showed that Eighty percent of mothers (80%) seek health care for their ill children. Of them, 70% went immediately to heath facility after disease occurrence. The person who took the decision of going to health facility (p-value=0.000) and work time for the health facility (p-value=0.001) were found to be significantly associated with mothers’ seeking behavior using bivariate and multivariate analysis. Since the person who took the decision of going to health facility is the most determinant for mothers’ seeking behavior, awareness rising among mothers about the importance of going to health facility immediately after disease occurrence can improve child health outcomes.
Unsupervised Large-Scale World Locations Dataset

Deep Learning systems require vasts amounts of data to be trained. Due to this, it is unfeasible to rely on humanlycurated datasets. Moreover, it is also needed to have access to large data collections (usually Internet-based and very noisy). To solve this challenge, this paper presents a) a novel approach to generate unsupervised large-scale classname-annotated landmark datasets and b) a system to reduce the noise in such datasets without supervision. To evaluate the robustness of the generated dataset, this paper compares the presented dataset with the Google Landmark dataset on a Landmark Recognitoin task, showing similar results on the Oxford5K and Paris6K sets. The noise filtering system is evaluated demonstrating successful results. The combination of the unsupervised dataset generation and the unsupervised noise filtering systems presented in this paper have the potential to drastically increase currently available landmark datasets and therefore its potential applications.
All About Cluster Headaches

According to the International Classification of Headache Disorders (ICHD), cluster headaches are a member of the trigeminal autonomic cephalalgia (TAC) family of headaches [1]. Trigeminal refers to the network of nerves that service the jaw, cheekbone, and eye regions of the face; autonomic refers to the features of runny nose, tearing, sweating, constricted eyelid, and sagging eyelid that accompany the attack; and cephalalgia refers to head. Other TACs include paroxysmal hemicrania, short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), and hemicrania continua. TACs differ from other headache classes (tension headaches and migraine) in that their durations are shorter, and they are accompanied by autonomic symptoms. As with all TACs, cluster headache is considered a primary headache disorder, meaning it is not caused by another disease or disorder. A headache that occurs in response to brain injury, tumor, or lesion would be a secondary, or "epiphenomenal" headache. Of all the TACs, cluster headache is the most common [2].
Aid for trade : An update on recent trends and 47 recent research and evaluation findings

Natural resource endowments in Mozambique, Tanzania and Uganda will give these countries stronger economic muscles. What will they use them for in the future? Based on the proposition that countryand sector-specific political dynamics are at the heart of different development outcomes, it is argued that ruling elites in the three countries will continue to prioritize social over productive sectors. Spending will – as is the case at present not be particularly targeted at poorer segments. This makes political sense in efforts to win elections and stay in power. However, with bigger financial muscles the influence of donors and the Washington Consensus will decline. States will take on a more pro-active role in extractive industries as well as in other productive sectors. The provision of aid will not be ‘business as usual’ either. Aid is still needed to reach post-2015 goals -even in some newly ‘rich’ countries – but recipients will be more selective in who they work with and on what conditions. Such answers are obviously somewhat speculative but they are needed to come to grips with some of the major changes that natural resource riches may bring about.
APPLICATION OF ARTIFICIAL NEURAL NETWORK TO PREDICT REFERENCE EVAPOTRANSPIRATION IN FAMAGUSTA, NORTH CYPRUS

Accuracy in reference evapotranspiration (ETo) esti ma ion is required for agricultural production, water resources management and planning. To this eff ect, a three layered Feed Forward Neural Network (FFNN) trained with Back Propagation (BP) algori thm was employed to predict monthly ETo in Famagusta region of Northern Cyprus for the pe riod 2017 – 2050. The models were trained with 2, 3, and 4 inputs, the most dominant parameter was obtained and the results were compared to Multilinear Regression (MLR) Model results. PenmanMonteith (PM) method was used to estimate the past ETo. The results deduced that FFNN models c an accurately predict ETo with higher efficiency than MLR models. Also in view of the obta ined results, wind speed (U 2) is the most dominant between the input parameters.
Validation of Solar/Optical Models for Louvered Shades Using a Broad Area Illumination Integrating Sphere

In recent years, much attention has been given to the analysis of windows with shading systems. If the solar and thermal performance of these systems can be accurately predicted, than building designers would be better able to include shading as an effective solar control device. In previous studies, a theoretical model that predicts the solar performance of louvered shading layers has been developed. The purpose of the present work is to validate those models through the use of a Broad-Area Illumination Integrating Sphere (BAI-IS). Such a device is capable of measuring the spectral directional-hemispheric properties of an inhomogeneous material or system (such as a Venetian blind). The experiments showed that the zero thickness slat assumption caused some error when the slat and profile angles are nearly aligned.

Peripheral serum progesterone profile in multiparous Nigerian Red Sokoto goats between day one and 30 postpartum

Peripheral serum progesterone (P 4 ) profile as an index of postpartum (pp) resumption of ovarian activity was determined in fifteen (15) multiparous Red Sokoto goats between day 1 and 30 pp. Serum P 4 was determined on day 1, 5, 9, 13, 17, 21, 25 and 30 pp, that is, on every 4th day after the preceeding sampling and on the 5th day after day 25 sampling. A total of 115 serum samples were analysed by radioimmunoassay. The mean P 4 concentration during the period of study was 0.19 ± 0.02 ng/mL. Two progestronic peaks were observed at day 5 and 17 pp. The highest P 4 concentration occurred on day 17 pp (0.26 ± 0.07 ng/mL) and the lowest level on day 25 pp ( 0.05). It is concluded that ovarian activity in the early pp period is characterized by fluctuating short-term luteal phases and may resume as early as day 5 pp in multiparous Red Sokoto goat.
ENVIRONMENTAL COST DISCLOSURE AND FINANCIAL PERFORMANCE OF OIL AND GAS IN NIGERIA

The United Nations Organization (UNO) has done tremendous work on the issue of environmental activities in the different aspect concerning conservation, sustainability, management, protection and control and the overall impact on the world economy. This study empirically examines the effect of environmental cost disclosure and financial performance measures of quoted oil and gas companies in Nigeria. Time series data were collected from annual financial reporting and economic review of Central Bank of Nigeria; Pearson product moment coefficient of correlation and multiple linear regression analysis with the aid of special package for social sciences (SPSS) version 22. The econometric results reviewed adequate disclosure on environmental cost, compliance to corporate environmental regulations have positive significant effect on financial performance measures. Thus the study recommended regulatory enforcement for adequate environmental cost disclosure and proper reporting. Management of oil and gas companies in Nigeria should develop a wellarticulated environmental costing system in order to guarantee a conflict free corporate atmosphere for improved corporate performance.

FTRLIM Results for OAEI 2019

To achieve better eﬃciency and feasibility in instance matching between two datasets, we proposed a system named FTRLIM, which is based on the FTRL (Follow the Regularized Leader) model. The FTR-LIM system supports the generation of indexes for instances, which enables the system to ﬁgure out possible matching instance pairs eﬃciently. FTRLIM participated in the SPIMBENCH track of OAEI 2019, and obtained the highest F-measure in SANDBOX and almost the highest F-measure in MAINBOX, with the least time cost. The results also provided potential directions for further improvement of FTRLIM.
Conceptualizing Complex Post-Traumatic Stress: The Roles of Dissociation, Attachment, and Type of Traumatic Event by

Those who experience relational traumatic events (i.e., traumatic events wherein there is a pre-existing relationship with the perpetrator such as intimate partner violence or some types of child maltreatment) often present with issues of affect regulation and poor self-concept, as well as functional impairment; which can be characterized as complex post-traumatic stress disorder (Complex PTSD). The roles of dissociation, adult attachment style and traumatic event type in Complex PTSD have yet to be fully examined. Using an undergraduate sample (n = 580), I examined the symptom structure of Complex PTSD using confirmatory factor analysis to test a model with four first-order latent variables and one second-order latent variable, each consisting of three to four observed variables: (1) PTS (re-experiencing, avoidance, hypervigilance); (2) Affect Dysregulation (skill deficits, instability, tension-reducing activities); (3) Dissociation (depersonalization, derealization, disengagement and emotional constriction); (4) Negative SelfConcept (self-blame, self-criticism, helplessness); and (5) Interpersonal Difficulties (difficulty with intimacy, interpersonal conflicts, fearful-avoidant adult attachment style); and the secondorder latent factor of (6) Complex PTS. The model demonstrated a good fit with moderate to high factor loadings. Next, I used structural equation modelling to examine if relational traumatic events were associated with Complex PTS, and if non-relational types of traumatic events were associated with PTS. The model demonstrated a good fit with moderate to high factor loadings, however the association between PTS and non-relational traumatic events was not significant. I then used latent profile analysis to examine whether those who endorse Complex PTS symptoms represent a distinct population from those who endorse only PTS symptoms. A two-group solution was the best fit to the data wherein one group endorsed low levels of all symptoms and
