Foliated Stratified Spaces and a De Rham Complex Describing Intersection Space Cohomology

The method of intersection spaces associates cell-complexes depending on a perversity to certain types of stratified pseudomanifolds in such a way that Poincar\'e duality holds between the ordinary rational cohomology groups of the cell-complexes associated to complementary perversities. The cohomology of these intersection spaces defines a cohomology theory HI for singular spaces, which is not isomorphic to intersection cohomology IH. Mirror symmetry tends to interchange IH and HI. The theory IH can be tied to type IIA string theory, while HI can be tied to IIB theory. For pseudomanifolds with stratification depth 1 and flat link bundles, the present paper provides a de Rham-theoretic description of the theory HI by a complex of global smooth differential forms on the top stratum. We prove that the wedge product of forms introduces a perversity-internal cup product on HI, for every perversity. Flat link bundles arise for example in foliated stratified spaces and in reductive Borel-Serre compactifications of locally symmetric spaces. A precise topological definition of the notion of a stratified foliation is given.
Evaluation of the Performance of the New EGM2008 Global Geopotential Model over Poland

The performance of the new EGM2008 global geopotential model, over Poland, has been evaluated. The tide-free release of the EGM2008 model was also used for the assessment of quality of three precise quasigeoid models developed in the last decade in Poland. The EGM2008 model was compared with GPS/levelling as well as regional gravimetric quasigeoid models. The results obtained confirm high quality of quasigeoid models in Poland. They are in agreement with the previous estimate of their accuracy. Regional quasigeoid model calculated using the EGM2008 model has been found fully comparable with the existing precise quasigeoid models. EGM2008-based quasigeoid model was used to detect outlying GPS/levelling heights in the data set used for the assessment of quality of gravimetric quasigeoid models in Poland.
Exploring differences between private and public organizations in business excellence models

This study aims to explore the differences between public and private organizations in the paths of business excellence models and to identify the key drivers for creating business results and customer satisfaction. The partial least squares structural equation modeling technique is used to compare the path coefficients and to identify the key driver constructs for creating business results. The variation in endogenous constructs is found to be more difficult to explain or predict for private organizations than for public organizations, despite the fact that the performance of private organizations is almost always higher than or equal to the performance of public ones in all criteria. The effect of ‘leadership’ on ‘management of processes’ is significantly higher in public organizations than in private ones. However, ‘management of processes’ in public organizations does not seem to translate into ‘results’. The effect of ‘strategic planning’ on creating business ‘results’ is negative for public organizations and remains inconclusive, due to insufficient evidence, for private organizations. The results may not be generally applicable to other countries. However, they do support the move toward more tailor-made models for specific sectors. It is necessary to review the national business excellence model in order to fit specific sectors. This is the first study to investigate the differences between private and public organizations in the Swedish business excellence model.
THE MITIGATION OF SCIENTIFIC CLAIMS IN RESEARCH PAPERS: A COMPARATIVE STUDY

In the context of academic writing, authors tend to mitigate the force of their scientific claims by means of hedging devices in order to reduce the risk of opposition and minimise the face threatening acts that are involved in the making of claims. This study explores the phenomenon of hedging in the research article (RA) from a cross-cultural perspective. To this end, a total of 40 RAs written in English and Spanish in the field of Clinical and Health Psychology were analysed in terms of the frequency of occurrence and distribution of the various strategies and the linguistic devices associated to each strategy which perform a hedging function in the different structural units of the articles. The results of the comparative quantitative analyses revealed that there are similarities between the two languages regarding the distribution of hedges across the structural units of the RAs, although a certain degree of rhetorical variation was also found mainly in terms of the frequency of use of the strategy of indetermination (i.e. modality devices and approximators) which occurs to a much greater extent in the English texts. This suggests that the English RAs in the field of Clinical and Health Psychology, as a whole, involve more protection to the author’s face.
A Longitudinal Study of the Relationship between Support Reciprocity and Mental Health (2): Focusing on the Early Stage of Friendship Development among Junior High School Students

This study focuses on the early stage of friendship development, and longitudinally examines the relationship between support reciprocity and mental health among junior high school students. The participants were 118 new students of junior high school (74 boys and 44 girls). A questionnaire package was administered at two weeks, four weeks, and three months after matriculation. At the first time of investigation, they were asked to choose a new friend they got acquainted upon matriculation, and to complete questionnaires that measured support receiving and giving in a friendship, stress responses, and relationship intimacy each time. For students whose relationship with a friend remained at a superficial level at three months after entering school, support receiving and giving in a friendship decreased over time. At either time of study, support reciprocity did not correlate significantly with stress responses, confirming the previous research results.
The Relationships among Salary, Altruistic Behavior and Job Performance in the National Basketball Association

During the 2011-12 National Basketball Association (NBA) season, the senior staffs and team players often hold different opinions on salary which results in the suspension of the game. The senior staffs want to cut human resource cost while team players would care much about their salary and interests. Therefore, the senior staff can set up a sound salary system to improve the altruistic behavior of the players as well as reduce extra human resource cost. The purpose of this study is to explore the effect of salary on altruistic behavior and job performance and the mediating effect of altruistic behavior. With teams and players of the NBA 2011-12 Playoffs as the sample, the regression analysis is adopted to verify the hypotheses. It is found from the results that salary has a significant positive impact on altruistic behavior as well as job performance. Meanwhile, altruistic behavior has a significant positive impact on job performance and partly exerts mediating effect on the relationship between salary and job performance.
Epidemiological Factors and Pathomorphologic Characteristics of Hydatidiform Mole

Introduction: Hydatidiform mole is a gestational trophoblastic disease characterized by a range of disorders of abnormal trophoblastic proliferation.Methods: This was a retrospective study of 70 singletone pregnancies until the 12th week of gestational age diagnosed with hydatidiform mole or spontaneously aborted physiological pregnancy. The pregnantwomen had almost similar demographic features and were divided into two groups. 35 pregnant women with a molar pregnancy were included in the study group; while 35 pregnant women with physiologicalpregnancy spontaneously aborted were included in the control group. Analyzed parameters included a pregnant woman’s age, blood type, parity and previous pregnancies (course and outcomes). Results: In the study group 11.43% of cases had hydatidiform mola during previous pregnancies as well as the advanced average gestational age of an ongoing pregnancy (9.63±1.83 in contrast to 8.25±2.03in the control group). The pregnant women with the hydatidiform mole were reported to have statistically significantly greater number of irregular villous borders (71.43%); slightly enlarged villi (54.29%); moderatedpresence of cisterns (65.71%) as well as mild avascularisation of villi (57.14%). Conclusion: It was concluded that a previous molar pregnancy represents the highest risk for hydtidiforme mole and the pathomorphologic analysis of vilous changes can be a reliable parameter for establishingproper diagnosis of partial hydatidiform mole.
Exploiting Smartphones and Apps for Language Learning: A Case Study with The EFL Learners in a Bangladeshi University

Smartphones and apps making institutions are always coming up with innovative language facilitating softwares with a view to providing the users cum learners with much easier and more sophisticated advantages. EFL learners especially at the university level of Bangladesh are making the best use of these technological amenities in and out of the classrooms. This article endeavors to manifest the outcomes of a study conducted on a number of EFL learners majority of who are found to be exploiting English language learning apps comprehensively. It attempts to present how these apps can be better effectuated for the greater benefit of the EFL learners. With regard to pedagogical interest, this study aims to offer a feasible language teaching approach to the EFL instructors as well.
The erosion of African communal values: a reappraisal of the African Ubuntu philosophy

The paper, which exploits conceptual analysis techniques, interrogates an African notion of a ‘community’ as embodied in the ideas of ‘Umntu ngumntu ngabantu. ’ The problem the article seeks to address is the erosion of community values. The study intends to explore the question: How can we retrieve the communal cultural values of tolerance, humanity, respect and some of common elements of our cultural treasures of Ubuntu that African communities used to be proud of? Using the philosophy of Ubuntu as a hermeneutic key, I argue that any member of a community whose personal life is guided by Ubuntu could be said to have embraced the core humanistic attributes of Ubuntu. These are being caring, humble, thoughtful, considerate, understanding, wise, generous, hospitable, socially mature, socially sensitive, virtuous, and blessed: character attributes that veer away from confrontation towards conciliation. The paper is based on a small scale survey, which exploited an open ended questionnaire in its data collection. Data revealed that despite major constraints such as poverty and scarcity of resources, crime, substance abuse and many others, family members are still willing to help and support each other. Finally, the study suggests that the values of Ubuntu, if consciously harnessed, can play a major unifying role in the process of harmonising the South African/African nation(s). Key words: Community, communalism, African humanity, African philosophy, Ubuntu .
Taxes and Dividend Policy (The Case of Pakistan)

The paper investigates different firm specific factors that influence the decision relating to corporate dividend policy. The second aim of the study is to investigate the association between taxes and dividend policy, and to study the association between dividends, profits and taxes. The study sample consists of 120 Karachi Stock Exchange listed companies. The duration of the study is from 2000 to 2011. The sources of data are Karachi Stock Exchange, Securities and Exchange Commission of Pakistan, State Bank of Pakistan and the Audited Annual Reports from companies’ official websites. Using panal data technique the results indicate that variables liquidity, size and profitability have significant positive, whereas leverage has significant negative influence on dividend payments of companies. However the variable growth did not appear to have any significant influence on dividend payment behavior of companies. Using standard multiple regression for the accomplishment of second aim, we have found that the link between dependent variable profit and explanatory variable tax is positive but statistically insignificant. On the other hand dividend has direct positive correlation with profit. Keywords: Dividend policy, Karachi Stock Exchange, Bird in the hand theory

The current study aims to identify the factors causing lack of regular attendance at ANC clinics in primiparas and to determine the effects of lack of antenatal care on perinatal
Detection of CD10, CD34 and their combined expression on Childhood Acute Lymphoblastic Leukemia and the association with clinical outcome in Indonesia

Background: Immunophenotyping has been implemented in the diagnosis of children with acute leukemia in Yogyakarta, Indonesia. The aim of this study was to determine whether expression of CD10 and/or CD34 could be used as additional prognostic markers for children with acute lymphoblastic leukemia (ALL) treated on the Indonesia ALL 2006 protocol. Materials & Methods: Of 211 ALL patients immunophenotype was determined and related to clinical data. Patient outcome was calculated as overall survival and event free survival, in which events were defined as: induction failure, death or relapse. Results: In the overall patients cohort, combination of CD10 and/or CD34 expression is an independent favorable prognostic factor in both univariate and multivariate analyses. In B-lineage ALL expression of CD10, CD34 and CD10 + and/or CD34 + were: 78%, 59% and 90% respectively. Although CD10, CD34 and the combined expression were associated with favorable outcome in the overall cohort, none of these parameters remained a significant independent risk factor after multivariate analysis in B-lineage leukemia.
Generalized Marcinkiewicz-Zygmund type inequalities for random variables and applications

It is shown that if the higher order Marcinkiewicz-Zygmund type inequality holds, then some generalized Marcinkiewicz-Zygmund type inequality holds, in particular, the lower order Marcinkiewicz-Zygmund type inequality also holds. No additional assumptions are made on the random variables. As applications, a generalized Cr -inequality and a weak law of large numbers for pairwise independent random variables are obtained.
The Aluffi algebra

We deal with the quasi-symmetric algebra introduced by Paolo Aluffi, here named (embedded) Aluffi algebra. The algebra is a sort of "intermediate" algebra between the symmetric algebra and the Rees algebra of an ideal, which serves the purpose of introducing the characteristic cycle of a hypersurface in intersection theory. The results described in the present paper have an algebraic flavor and naturally connect with various themes of commutative algebra, such as standard bases \'a la Hironaka, Artin--Rees like questions, Valabrega--Valla ideals, ideals of linear type, relation type and analytic spread. We give estimates for the dimension of the Aluffi algebra and show that, pretty generally, the latter is equidimensional whenever the base ring is a hypersurface ring. There is a converse to this under certain conditions that essentially subsume the setup in Aluffi's theory, thus suggesting that this algebra will not handle cases other than the singular locus of a hypersurface. The torsion and the structure of the minimal primes of the algebra are clarified. In the case of a projective hypersurface the results are more precise and one is naturally led to look at families of projective plane singular curves to understand how the property of being of linear type deforms/specializes for the singular locus of a member. It is fairly elementary to show that the singular locus of an irreducible curve of degree at most 3 is of linear type. This is roundly false in degree larger than 4 and the picture looks pretty wild as we point out by means of some families. Degree 4 is the intriguing case. Here we are able to show that the singular locus of the generic member of a family of rational quartics, fixing the singularity type, is of linear type. We conjecture that every irreducible quartic has singular locus of linear type.
A Survey of CDIO Implementation Globally - Effects on Educational Quality

The CDIO approach to engineering education was introduced in the early 2000’s. Some universities have gained considerable long-term experience in applying the approach, and consequently it seems timely to summarize and evaluate those experiences. This paper thus reports the results of a survey distributed to all members of the CDIO Initiative in October 2014. The aims of the survey were to: • Map out where and in what programs/disciplines CDIO is currently applied • Evaluate the effects on outcomes, the perceived benefits, the limitations, any barriers to implementation, and ascertain future development needs

10 th Norwegian-German Seminar Public Sector Economics International Taxation and Productivity Effects of M&As

We investigate the e(cid:27)ect of international di(cid:27)erences in corporate taxation on the realization of productivity gains in M&A deals. We argue that tax di(cid:27)erentials distort the e(cid:30)cient allocation of productive factors following an M&A and thus mitigate the resulting productivity improvement. Using (cid:28)rm-level data on inputs and outputs of production as well as on corporate M&As, we estimate that a 1 percentage point increase in the absolute tax di(cid:27)erential between the locations of two merging (cid:28)rms reduces the subsequent total factor productivity gain by 4.5%. This e(cid:27)ect is less pronounced when (cid:28)rms can use international pro(cid:28)t shifting to attenuate e(cid:27)ective di(cid:27)erences in taxation. In a complementary analysis, we use an event study design and a (cid:28)xed e(cid:27)ects model to explore the timing of the response of productivity, as well as, labor and capital input to the tax rate di(cid:27)erential after the merger separately for the acquirer and the target. We show that our (cid:28)ndings are mainly driven by deals with targets residing in locations with a tax advantage with respect to the acquirer. In these transactions, tax di(cid:27)erentials reduce the post-merger adjustment in the target (cid:28)rm and inhibit the full realization of productivity gains.
Liquidity-augmented performance evaluation of Thai’s mutual funds

This study proposes a liquidity-augmented performance measure and investigates the performance of Thai mutual funds for the period of 2002-2007. Liquidity effects are found to have statistically significant impacts. Overall, the results provide no evidence of abnormal performance. The performance of tax-benefit funds, however, is found to be superior and statistically significantly different from that of general funds, even when the liquidity premium is controlled for. We find evidence of short-term persistence in performance when controlling for momentum effects.
All-fiber 7 × 1 signal combiner with high beam quality for high-power fiber lasers

All-fiber signal combiner is a key component for augmenting the fiber laser power. Presently the reported 7 × 1 signal combiners are all have output fibers with core diameters larger than 100 μm. In order to improve the beam quality of the combiner, a fiber with smaller core of 50 μm diameter is chose to be the output fiber. An all-fiber 7 × 1 signal combiner is fabricated with measured power transmission efficiency around 99% for each port. The beam quality is improved and the measured M2 are around 6 which are matched well with the theoretically calculated results. OCIS codes: 140.3510, 140.3298, 060.2310, 060.2340, 230.2285. doi: 10.3788/COL201513.061406.
Effect of aspirin for prevention of preeclampsia in women with abnormal ultrasonic findings in uterine artery

Background: Prevention of preeclampsia is very important in reducing maternal and neonatal mortality and morbidity. The purpose of this study was to determine the effectiveness of aspirin in the prevention of preeclampsia in high-risk pregnancies with abnormal findings at uterine artery in doppler ultrasound among women referred to ShabihKhani hospital in Kashan. Materials and Methods: In this clinical trial study, women predisposed to preeclampsia at 12-16 weeks of gestation were evaluated by uterine artery doppler ultrasound and in the case of abnormal findings, they were randomly divided into two groups, experimental (n=40) and control (n=40) groups. The experimental group was received aspirin 80 mg/day. Groups were followed up until delivery and pregnancy outcomes (e.g. incidence of preeclampsia, IUGR, preterm labour, 1st and 5th min APGAR less than 5, delivery type and birth weight) were analyzed. Results: The incidence of preeclampsia in experimental (aspirin) group and control group were 2.5%, 22.5%, respectively. In addition, the risk of preeclampsia was 9 folds more than that of control group (P=0.007). No significant difference was seen between the two groups in the type of delivery, birth weight and gestational age. Conclusion: Aspirin administration during 12-16 weeks of pregnancy can decrease the incidence of preeclampsia in high-risk pregnancy with abnormal findings of uterine artery as a preventive measure.
