Nurturing Leadership Development for the Now and the Next: A Denominational Perspective

The changes in our society signal a need for ministerial leaders who not only hold a nuanced understanding of the effects that these shifts have created and codified within congregations but also possess the leadership skills necessary to creatively and successfully guide these congregations through change in hopes of cultivating meaningful, contextually relevant ministries

Vibrational Zero-Point Energy of Organosilicon Compounds

In this chapter, the calculation of vibrational zero-point energies (ZPEs) of organosilicon compounds is reported. An empirical formula is used. This relationship was determined by relating vibrational zero-point energy to the nature and type of bonds forming the molecule. The calculated vibrational zero-point energies for several organosilicon derivatives belonging to different categories of compounds correlate well with the reported available values. In addition, the comparison of these results with the scaled values obtained using methods of quantum chemistry (AM1, ab initio, and by a similar empirical approach) indicates the reliability of our empirical model to reproduce vibrational zero-point energy of organosilicon compounds

Towards a new hybrid approach for building document-oriented data warehouses

Schemaless databases offer a large storage capacity while guaranteeing high performance in data processing. Unlike relational databases, which are rigid and have shown their limitations in managing large amounts of data. However, the absence of a well-defined schema and structure in not only SQL (NoSQL) databases makes the use of data for decision analysis purposes even more complex and difficult. In this paper, we propose an original approach to build a document-oriented data warehouse from unstructured data. The new approach follows a hybrid paradigm that combines data analysis and user requirements analysis. The first data-driven step exploits the fast and distributed processing of the spark engine to generate a general schema for each collection in the database. The second requirement-driven step consists of analyzing the semantics of the decisional requirements expressed in natural language and mapping them to the schemas of the collections. At the end of the process, a decisional schema is generated in JavaScript object notation (JSON) format and the data loading with the necessary transformations is performed

An improved algorithm of generating shortening patterns for polar codes

The rate matching in polar codes becomes a solution when non-conventional codewords of length N≠2n are required. Shortening is employed to design arbitrary rate codes from a mother code with a given rate. Based on the conventional shortening scheme, length of constructed polar codes is limited. In this paper, we demonstrate the presence of favorable and unfavorable shortening patterns. The structure of polar codes is leveraged to eliminate unfavorable shortening patterns, thereby reducing the search space. We generate an auxiliary matrix through likelihood and subsequently select the shortening bits from the matrix. Unlike different existing methods that offer only a single shortening pattern, our algorithm generates multiple favorable shortening patterns, encompassing all possible favorable configurations. This algorithm has a reduced complexity and suboptimal performance, effectively identifying shortening patterns and sets of frozen symbols for any polar code. Simulation results underscore that the shortened polar codes exhibit performance closely aligned with the mother codes. Our algorithm addresses this security concern by making it more difficult for an attacker to obtain the information set and frozen symbols of a polar code. This is done by generating multiple shortening patterns for any polar code

Access to higher education for undocumented students: “Outlaws” of social justice, equity, and equality

The status of access to higher education for undocumented students in this country is inconsistent from state to state, region to region, and the nation at large. This inconsistency is reflected in the development of policies and legislation that either provide or limit access to an affordable higher education for these students. Beneath the external debates regarding the application of instate tuition rates for undocumented students exists an underlying struggle embedded within an inherent cultural, societal, and systemic bias around beliefs, power, and privilege. The marginalization of undocumented students in accessing higher education—as evidenced by the absence of social justice, equity, and equality—has created an underground movement that is based in feminist and critical race theory descriptions of “outlaw culture.” This framework encapsulates the phenomenon of outlaw culture within the confines of systemic barriers, whereby those in positions closest to the front lines of service and access to higher education may become “outlaws” in bending, breaking, or circumventing the rules and regulations that perpetuate inequity and inequality and inhibit a socially just process for undocumented students. Implications regarding policy and practices to address socially just, equitable, and equal processes for access to higher education for undocumented students are presented for future consideration
