The spread of non‐native species
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Counting Peaks at Height k in a Dyck Path
of steps (1; 1) and (1; 1), which never passes below the x-axis. A peak at height k on a Dyck path is a point on the path with coordinate y = k that is immediately preceded by a (1; 1) step and immediately followed by a (1; 1) step.

The statistic “number of udu's” in Dyck paths
This paper studies the enumeration of Dyck paths by the number of \(udu\)'s (up-down-up). More precisely, the enumeration of Dyck paths with given semilength and given number of \(udu\)'s is obtained. An \(udu\) is said to be at low (high) level, if its peak is at level (greater than) one.

Do Major Customers Affect Firms' Environmental, Social and Governance Activities?
ABSTRACT We examine the role of major customers in shaping firms' environmental, social and governance (ESG) practices. We find that firms with major customer relationships undertake fewer ESG activities compared to those without such ties. The association is attenuated when institutional ownership is high, firms are less diversified, customers exhibit

Leader‐Follower Dynamics in Shareholder Activism
ABSTRACT We propose a theory of coordination and influence among blockholders. Privately informed activists time their trades in sequence to lower acquisition costs, prompting a strategic use of order flows: leader activists create trading gains for their followers, ultimately influencing their willingness to bear greater value‐enhancing intervention ...

Today many bug detecting tools use static program analysis techniques to discover the vulnerabilities in programs, and many static program analyses can be converted to CFL (Context-Free-Language) reachability problems, most of which are Dyck-CFL ...

Weighted Dyck paths for nonstationary queues [PDF]
We consider a model for a queue in which only a fixed number $N$ of customers can join. Each customer joins the queue independently at an exponentially distributed time.

ABSTRACT Project failures are common in innovative organizations, and mitigating the negative consequences on R&D employees' job attitudes and outcomes is a critical managerial task. While prior research has emphasized the motivational costs and coping mechanisms associated with experiencing personal project failure, the demotivational impact of ...

Intervals in Dyck Paths and the Wreath Conjecture
Let $\iota_{k}(m,l)$ denote the total number of intervals of length $m$ across all Dyck paths of semilength $k$ such that each interval contains precisely $l$ falls. We give the formula for $\iota_{k}(m,l)$ and show that $\iota_{k}(k,l)=\binom{k}{l}^2$.
