A new approach to generic functional programming

Ralf Hinze
2000 Proceedings of the 27th ACM SIGPLAN-SIGACT symposium on Principles of programming languages - POPL '00  
A generic function is one that is defined by induction on the structure of types. Typical examples include pretty printers, parsers, and comparison functions.  ...  The key idea of the approach is to model types by terms of the simply typed X-calculus augmented by a family of recursion operators.  ...  Acknowledgements I am grateful to Ian Bayley, Johan Jeuring, Lambert Meertens, and Fritz Ruehr for suggesting dozens of improvements regarding contents and presentation.  ...

Moderating Effects of Project Management Experience, Project Team Size, Project Duration and Project Value Size on the Relationship between Project Manager's Leadership Roles and Project Team Effectiveness in Malaysia

Han-Ping Fung
2015 Journal of Empirical Studies  
Based on a sample of 201 project managers, this empirical study had confirmed that a project manager's leadership roles are positively influencing project team effectiveness.  ...  The current study developed a research model underpinned on models related to Quinn (1988) leadership roles and Hoevemeyer (1993) five criteria of project team effectiveness as well as four demographic  ...  Lastly, both project team size and project value size have no moderating effect on the relationship between a project manager's leadership roles and project team effectiveness.  ...

Towards a symmetric approach to high energy evolution: Generating functional with pomeron loops

E. Levin, M. Lublinsky
2005 Nuclear Physics A  
We derive an evolution equation for the generating functional which accounts for processes for both gluon emission and recombination.  ...  The introduction of dipole recombination allows one to obtained closed loops during the evolution, which should be interpreted as Pomeron loops of the BFKL Pomerons.  ...  Acknowledgments: We want to thank Asher Gotsman, Alex Kovner and Uri Maor for very useful discussions on the subject of this paper.  ...

S. Baars, J.P. Viebahn, T.E. Mulder, C. Kuehn, F.W. Wubs, H.A. Dijkstra
2017 Journal of Computational Physics  
Key innovation is the efficient solution of a generalized Lyapunov equation using an iterative method involving low-rank approximations.  ...  We apply and illustrate the capabilities of the method using a problem in physical oceanography, i.e. the occurrence of multiple steady states of the Atlantic Ocean circulation.  ...  CK has been supported by an APART fellowship of the Austrian Academy of Sciences and by a Lichtenberg Professorship of the VolkswagenStiftung.  ...

THE EFFECT OF PROJECTION ON DERIVED MASS-SIZE AND LINEWIDTH-SIZE RELATIONSHIPS

Rahul Shetty, David C. Collins, Jens Kauffmann, Alyssa A. Goodman, Erik W. Rosolowsky, Michael L. Norman
2010 Astrophysical Journal  
Using the result of a hydrodynamic simulation of a molecular cloud, we investigate how geometric projection may affect the derived Larson relationships.  ...  Including thermal pressure in the simulated linewidths imposes a minimum linewidth, which results in a better agreement in the slopes of the linewidth-size relationships, though there are still discrepancies  ...  K., and A.  ...

On the size of Spell-Out domains: Arguments for Spell-Out of intermediate projections [article]

Akihiko Arano
2021 Zenodo  
It regulates the distribution of functional items within a Spell-Out domain.  ...  Contrary to this, the present paper proposes that a traditional intermediate or bar-level projection of phase heads constitutes Spell-Out domains if a phase head is in a spec-head agreement relation.  ...  at various stages of the paper.  ...

A generating function approach to Markov chains undergoing binomial catastrophes [article]

Branda Goncalves, Thierry Huillet
2021 arXiv   pre-print
Using a generating function approach, we study two versions of such population models when the binomial catastrophic events are of a slightly different random nature.  ...  In a Markov chain population model subject to catastrophes, random immigration events (birth), promoting growth, are in balance with the effect of binomial catastrophes that cause recurrent mass removal  ...  Huillet acknowledge support from the labex MME-DII Center of Excellence (Modèles mathématiques etéconomiques de la dynamique, de l'incertitude et des interactions, ANR-11-LABX-0023-01 project).  ...

Generalization in fifth graders within a functional approach

Eder Pinto, María C. Cañadas
2018 PNA  
Analyzed in the context of the functional approach of early algebra, the findings show that three students generalized both when solving specific instances and when asked to provide the general formula  ...  This article discusses evidence of 24 fifth graders' (10)(11) year olds') ability to generalize when solving a problem which involves a linear function.  ...  In fact, they generalized on the grounds of correspondence functional relationships that involved the values of a set of variables.  ...

The impact of increasing team size on project productivity

Yueh-Yuan Lai, Chiu-Chi Wei, Chiou-Shuei Wei
2017 Pressacademia  
Methodology-The challenge facing a project manager in this era is how to complete a project quickly, and one of the most commonly used methods is crashing, which implies shortening the project duration  ...  Traditionally, it is a common believe that increasing the number of workers can certainly reduce the project length; even the law of diminishing return is widely recognized.  ...  A team is formed by managers to achieve the objective of the project, such as developing the next generation products within a specified timeframe.  ...

A generating function approach to new representation stability phenomena in orbit configuration spaces [article]

Christin Bibby, Nir Gadish
2020 arXiv   pre-print
As countless examples show, it can be fruitful to study a sequence of complicated objects all at once via the formalism of generating functions.  ...  This idea allows for a factorization of the orbit configuration space "generating function" into an infinite product, whose terms are surprisingly easy to understand.  ...  The set of (G/H)-colorings on [n], i.e. the set of functions [n] → G/H, admits a transitive action of the wreath product group S n [G], and the stabilizer of the constant function k → 1H is the wreath  ...
