Leading For The Bottom Line: A View Of Leadership In A Bottom-Line Context

This paper sets out to establish and describe a new approach to leadership called Bottom Line Leadership. The essence of Bottom Line Leadership is that a leader’s most critical responsibility is to clearly identify, communicate and gain buy-in for the ultimate bottom-line objective of the organization he/she leads, subject to constraints imposed by the market and by the organization itself. In comparison to other leadership models that focus on the general attributes or behaviors characterizing effective leaders, Bottom Line Leadership emphasizes the link between an organization’s purpose and a leader’s behavior. The philosophy that serves as the foundation for this article stipulates that employees, in any type of organization, need to be crystal clear about the purpose and bottom-line objective of the organization they work for. Having this clarity of objective enables employees to not only understand the importance of an organization’s strategy and mission; it also allows them to make sound decisions in support of the organization’s goals. We believe that it is essential that leaders in organizations instill this clarity of purpose and help create the conditions that allow people to channel their energies into the appropriate activities. What results from our leadership and management research is a “virtuous circle” model coupled with a checklist that prescribes precisely what Bottom-Line Leaders do. To arrive at our model of Bottom-Line Leadership, we review the teachings of some of the most popular leadership and management thought leaders. We conclude that effective leadership actually encompasses both traditional leadership attributes (create / inspire / influence) and traditional management capabilities (deploy / control / execute). In short, what we find is that Bottom-Line Leaders instill clarity of purpose in their organization, gain commitment to the ultimate bottom-line objective, and engage employees in these efforts. They do this by deploying methods of communication, inspiration and motivation that constantly maintain a connection to, and are aligned with, the ultimate bottom-line objective the organization is striving to achieve. They also work tirelessly to ensure that employees are in a position to make decisions and take actions in manners supporting the bottom-line objective. In our view, leaders are those who do the right things right and get their people to do likewise

Testing and Data Recovery Excavations at 41BU51, Burleson County, Texas

Prewitt and Associates, Inc. (PAI), conducted archeological testing and data recovery excavations at prehistoric site 41BU51 in Burleson County, Texas, for the Texas Department of Transportation, Environmental Affairs Division, in three phases of investigation. The first phase of testing, conducted in Spring 2003, resulted in the discovery of a single human burial as well as diagnostic artifacts ranging from the Archaic period through the Late Prehistoric period. A second phase of testing was conducted to search for additional burials in January 2004. This work resulted in the discovery of three additional burials and two isolated human bones. Finally, data recovery to remove the human remains was conducted in June 2007. This report describes all three phases of work. Analysis of the data recovered indicates that 41BU51 has a Late Archaic component that contributed many or even most of the lithic artifacts, most of the burned rocks and burned clay, some or all of the ceramic artifacts, and probably all of the human burials. Materials representing Late Prehistoric period occupations also are present, and the possibility exists that large numbers of the lithic artifacts in the upper 60 cm of the deposits were left by these occupations. A small number of artifacts predating the Late Archaic period were recovered, but these are older items recycled into younger deposits. Radiocarbon dates indicate that the Late Archaic and Late Prehistoric use of the site occurred over perhaps 3,200 to 3,600 years. The vertical distributions of the temporally sensitive artifacts and the radiocarbon dates, while hinting at some remnant time-related stratification of the cultural materials, make it clear that there has been much mixing of the deposits, presumably through faunal turbation and other forms of disturbance. With this degree of mixing, it is impossible to segregate the remains by time period or more-discrete components. Nonetheless, the archeological remains recovered indicate that 41BU51 was used intermittently over a long span of time, probably as a residential campsite, with some occupations during the Late Archaic period perhaps being for extended periods of time

Testing And Data Recovery Excavations At The Jayroe Site (41HM51), Hamilton County, Texas

In 2003–2004, Prewitt and Associates, Inc., performed National Register of Historic Places testing and subsequent data recovery excavations at the Jayroe site (41HM51) in Hamilton County for the Texas Department of Transportation, Environmental Affairs Division, under Texas Antiquities Permit Nos. 3211 and 3405. The investigations were prompted by the planned replacement of the County Road 294 bridge at the Leon River (CSJ No. 0909-29-030), in compliance with Section 106 of the National Historic Preservation Act and its implementing regulations (36 CFR Part 800) and the Antiquities Code of Texas. Testing consisted of the excavation of 6 backhoe trenches and 19 test units, and the data recovery work consisted mainly of hand excavation of 153 contiguous 1x1-m units within a single block, with 2 backhoe trenches and 2 manual units apart from the block excavation. Combined, the testing and data recovery identified 16 cultural features interpreted as 3 open hearths, 4 shallow earth ovens or surface hearths, 8 scatters of various kinds of debris, and 1 knapping station. The excavations recovered 322 chipped stone tools, 26 cores, 6,589 pieces of unmodified debitage, 21 ground or battered stone tools, 38 potential pigment sources, 43 ceramic sherds, 15 modified bone artifacts, 7,649 animal bones, 1,200 mussel shells, and macrobotanical remains. Four analytical units are defined for the site, only one of which—the Toyah phase component— has much interpretive potential. It is interpreted as a campsite used at least several times, mostly in the a.d. 1470s, at which butchering of mostly bison and deer, late-stage lithic tool manufacture and repair, and other maintenance tasks figured prominently in the site activities. The artifacts recovered and records generated by the project are curated at the Center for Archaeological Studies, Texas State University

A High Performance Payment Processing System Designed for Central Bank Digital Currencies

In light of continued innovation in money and payments, many central banks are exploring the creation of a central bank digital currency (CBDC), a new form of central bank money which supplements existing central bank reserve account balances and physical currency. This paper presents Hamilton, a flexible transaction processor design that supports a range of models for a CBDC and minimizes data storage in the core transaction processor by storing unspent funds as opaque hashes. Hamilton supports users custodying their own funds or custody provided by financial intermediaries. We describe and evaluate two implementations: the atomizer architecture which provides a globally ordered history of transactions but is limited in throughput (170,000 transactions per second), and the 2PC architecture that scales peak throughput almost linearly with resources (up to a measured throughput of 1.7M transactions per second) but does not provide a globally ordered list of transactions. We released our two architectures under the MIT open source license at https://github.com/mit-dci/opencbdc-tx

Wireless Programmable Recording and Stimulation of Deep Brain Activity in Freely Moving Humans.

Uncovering the neural mechanisms underlying human natural ambulatory behavior is a major challenge for neuroscience. Current commercially available implantable devices that allow for recording and stimulation of deep brain activity in humans can provide invaluable intrinsic brain signals but are not inherently designed for research and thus lack flexible control and integration with wearable sensors. We developed a mobile deep brain recording and stimulation (Mo-DBRS) platform that enables wireless and programmable intracranial electroencephalographic recording and electrical stimulation integrated and synchronized with virtual reality/augmented reality (VR/AR) and wearables capable of external measurements (e.g., motion capture, heart rate, skin conductance, respiration, eye tracking, and scalp EEG). When used in freely moving humans with implanted neural devices, this platform is adaptable to ecologically valid environments conducive to elucidating the neural mechanisms underlying naturalistic behaviors and to the development of viable therapies for neurologic and psychiatric disorders

Data from: Draft assembly of elite inbred line PH207 provides insights into genomic and transcriptome diversity in maize

Intense artificial selection over the last 100 years has produced elite maize (Zea mays) inbred lines that combine to produce high-yielding hybrids. To further our understanding of how genome and transcriptome variation contribute to the production of high-yielding hybrids, we generated a draft genome assembly of the inbred line PH207 to complement and compare with the existing B73 reference sequence. B73 is a founder of the Stiff Stalk germplasm pool, while PH207 is a founder of Iodent germplasm, both of which have contributed substantially to the production of temperate commercial maize and are combined to make heterotic hybrids. Comparison of these two assemblies revealed over 2,500 genes present in only one of the two genotypes and 136 gene families that have undergone extensive expansion or contraction. Transcriptome profiling revealed extensive expression variation, with as many as 10,564 differentially expressed transcripts and 7,128 transcripts expressed in only one of the two genotypes in a single tissue. Genotype-specific genes were more likely to have tissue/condition-specific expression and lower transcript abundance. The availability of a high-quality genome assembly for the elite maize inbred PH207 expands our knowledge of the breadth of natural genome and transcriptome variation in elite maize inbred lines across heterotic pools
