Evaluating Father Involvement in the Voluntary Family Maintenance and Reunification Process
ACTION’s Community Case Management program works collaboratively with Monterey County Department of Social Services’ Family and Children Services’ Voluntary Family Maintenance and Voluntary Family Reunification unit, to keep children safe at home and out of the court system. Recurrent child maltreatment rates are too high in voluntary and court-ordered child protective services. Various factors contribute to father involvement and engagement in family stabilization efforts. This capstone was an exploratory research project that assessed father involvement in parent education services for families that were referred to voluntary child protective services in Monterey County. This project aimed to increase awareness on the importance of father involvement in prevention and intervention services, with a focus on engaging fathers, if present, in voluntary services. Findings suggest that father involvement is related to program completion, but additional research is recommended to prove the statistical correlation
The Achievement Gap: How Are English Language Learners Being Impacted By The U.S. Education System?
This capstone paper explores individual experiences of English learners in a South County Monterey academic environment in order to better inform future teachers. This qualitative case study explores seven English learners\u27 individual experiences and focuses on addressing the following questions: What experiences impact English language learners’ (ELLs) academic development in the US? What are the primary factors that contribute to the achievement gap ELL’s face? How does society’s views impact ELL’s? What factors can provide a better academic experience? In order to further investigate the experience of ELLs in US schools, this study sought research and gathered information through different peer-reviewed articles, websites, books, journals, magazines, and interviews to gain a better understanding of the factors which impact the academic development of ELLs. After examining the factors contributing to ELLs’ achievement gap, this study encompasses different experiences of ELLs and approaches which may provide ELL students with a richer learning environment
Identity, Equality, Nameability and Completeness
This article is an extended promenade strolling along the winding roads of identity, equality, nameability and completeness, looking for places where they converge. We have distinguished between identity and equality; the first is a binary relation between objects while the second is a symbolic relation between terms. Owing to the central role the notion of identity plays in logic, you can be interested either in how to define it using other logical concepts or in the opposite scheme. In the first case, one investigates what kind of logic is required. In the second case, one is interested in the definition of the other logical concepts (connectives and quantifiers) in terms of the identity relation, using also abstraction. The present paper investigates whether identity can be introduced by definition arriving to the conclusion that only in full higher-order logic a reliable definition of identity is possible. However, the definition needs the standard semantics and we know that with this semantics completeness is lost. We have also studied the relationship of equality with comprehension and extensionality and pointed out the relevant role played by these two axioms in Henkin’s completeness method. We finish our paper with a section devoted to general semantics, where the role played by the nameable hierarchy of types is the key in Henkin’s completeness method
Identity, equality, nameability and completeness. Part II
This article is a continuation of our promenade along the winding roads of identity, equality, nameability and completeness. We continue looking for a place where all these concepts converge. We assume that identity is a binary relation between objects while equality is a symbolic relation between terms. Identity plays a central role in logic and we have looked at it from two different points of view. In one case, identity is a notion which has to be defined and, in the other case, identity is a notion used to define other logical concepts. In our previous paper, [16], we investigated whether identity can be introduced by definition arriving to the conclusion that only in full higher-order logic with standard semantics a reliable definition of identity is possible. In the present study we have moved to modal logic and realized that here we can distinguish in the formal language between two different equality symbols, the first one shall be interpreted as extensional genuine identity and only applies for objects, the second one applies for non rigid terms and has the characteristic of synonymy. We have also analyzed the hybrid modal logic where we can introduce rigid terms by definition and can express that two worlds are identical by using the nominals and the @ operator. We finish our paper in the kingdom of identity where the only primitives are lambda and equality. Here we show how other logical concepts can be defined in terms of the identity relation. We have found at the end of our walk a possible point of convergence in the logic Equational Hybrid Propositional Type Theory (EHPTT), [14] and [15].This research has been possible thanks to the research projects sustained by Ministerio de Econom´ıa y Competitividad of Spain with references FFI2013-47126-P and FFI2017-82554-

Product line architecture recovery with outlier filtering in software families: the Apo-Games case study
Software product line (SPL) approach has been widely adopted to achieve systematic reuse in families of software products. Despite its benefits, developing an SPL from scratch requires high up-front investment. Because of that, organizations commonly create product variants with opportunistic reuse approaches (e.g., copy-and-paste or clone-and-own). However, maintenance and evolution of a large number of product variants is a challenging task. In this context, a family of products developed opportunistically is a good starting point to adopt SPLs, known as extractive approach for SPL adoption. One of the initial phases of the extractive approach is the recovery and definition of a product line architecture (PLA) based on existing software variants, to support variant derivation and also to allow the customization according to customers’ needs. The problem of defining a PLA from existing system variants is that some variants can become highly unrelated to their predecessors, known as outlier variants. The inclusion of outlier variants in the PLA recovery leads to additional effort and noise in the common structure and complicates architectural decisions. In this work, we present an automatic approach to identify and filter outlier variants during the recovery and definition of PLAs. Our approach identifies the minimum subset of cross-product architectural information for an effective PLA recovery. To evaluate our approach, we focus on real-world variants of the Apo-Games family. We recover a PLA taking as input 34 Apo-Game variants developed by using opportunistic reuse. The results provided evidence that our automatic approach is able to identify and filter outlier variants, allowing to eliminate exclusive packages and classes without removing the whole variant. We consider that the recovered PLA can help domain experts to take informed decisions to support SPL adoption.This research was partially funded by INES 2.0; CNPq grants 465614/2014-0 and 408356/2018-9; and FAPESB grants JCB0060/2016 and BOL2443/201

Comparing performance on chaos control via adaptive output-feedback
"Performance of four controllers is experimentally compared and evaluated in context of chaos suppression. Four output-feedback controllers are used in experi- ments for comparison. First three schemes utilize an adaptive observer to estimate the states and parameter required for feeding back and with different techniques, which are: (i) feedback linearization, (ii) backstepping, and (iii) sliding mode. The fourth scheme is a (low-parameterized) robust adaptive feedback. A simple class of dynamical systems that exhibit chaotic behavior, called P-class, is considered as benchmark due to involves distinct chaotic systems. The need of comparison is motivated to ask: What is the suitable adaptive scheme to suppress chaos in an specific implementation? Results show a trend on different applications, are illustrated experimentally by means circuits, and are discussed in terms of control effort. This comparative study is important to select a feedback scheme in specific implementations; for example, synchronization of complex networks.
