This study aimed to investigate the longitudinal trends in mathematical competencies of Grade 8 students in a public high school located in Zamboanga del Sur, Philippines. The study collected data over a period of six academic years, allowing for a comprehensive analysis of students' performance in 16 distinct mathematical competences of basic education curriculum. These topics include, but are not limited to, special products and factors, factoring, and basic concepts of probability. Using a quantitative research design, the study analyzed both (...) numerical and secondary data to identify patterns or trends in students' mathematical competencies. Trends were analyzed through regression analysis using slopes. The significance of these trends was then evaluated using t-tests for the standard error of slopes. The statistical analysis revealed significant upward trends in certain mathematical topics, indicating an improvement in the students' competencies over the six academic years. However, certain topics displayed downward or stable trends, indicating areas for improvement in the teaching methods used for these topics. The study highlights the importance of flexible and adaptable approaches to mathematics education. It emphasizes the need for constant evaluation and improvement of teaching methods to enhance student learning outcomes. The findings of this study provide valuable insights for educators and policymakers to guide evidence-based decision-making and improve the quality of mathematics education in the new normal setup. Implications and future research directions are incorporated in the study. (shrink)

In this paper, I submit that it is the controlled part of skilled action, that is, that part of an action that accounts for the exact, nuanced ways in which a skilled performer modifies, adjusts and guides her performance for which an adequate, philosophical theory of skill must account. I will argue that neither Jason Stanley nor Hubert Dreyfus have an adequate account of control. Further, and perhaps surprisingly, I will argue that both Stanley and Dreyfus relinquish an account of (...) control for precisely the same reason: each reduce control to a passive, mechanistic, automatic process, which then prevents them from producing a substantive account of how controlled processes can be characterized by seemingly intelligent features and integrated with personal-level states. I will end by introducing three different kinds of control, which are constitutive of skilled action: strategic control, selective, top–down, automatic attention, and motor control. It will become clear that Dreyfus cannot account for any of these three kinds of control while Stanley has difficulty tackling the two latter kinds. (shrink)

Recent experiments have shown that when individuals with a substance use disorder are confronted with drug-related cues, they exhibit an automatically activated tendency to approach these cues. The strength of the drug approach bias has been associated with clinically relevant measures, such as increased drug craving and relapse, and activations in brain reward areas. Retraining the approach bias by means of cognitive bias modification has been demonstrated to decrease relapse rates in patients with an alcohol use disorder and to reduce (...) alcohol cue-evoked limbic activity. Here, we review empirical and theoretical literature on the drug approach bias and explore two distinct models of how the drug approach bias may be embodied. First, we consider the “biological meaning” hypothesis, which grounds the automatic approach bias in the natural meaning of the body. Second, we consider the “sensorimotor hypothesis,” which appeals to the specific sensorimotor loops involved in the instantiation of addictive behaviors as the basis of the automatic approach bias. In order to differentiate between the adequacies of these competing explanations, we present specific, predictions that each model should make. (shrink)

Metaphors abound in descriptions of the COVID-19 pandemic: it is described, among other things, as a war, a flood, and a marathon. However, not all metaphors may resonate equally well with members...

The philosophy of family‐centered care (FCC) promotes partnerships between families and staff to plan, deliver, and evaluate services for children and has been officially adopted by a majority of pediatric hospitals throughout North America. However, studies indicated that many parents have continued to be dissatisfied with their decision‐making roles in their child's care. This is particularly salient for parents of children with chronic ongoing complex health problems. These children are dependent upon medical technology and require frequent hospitalizations during which parents (...) must contribute to difficult decisions regarding their child's care. Given this clinical issue, an alternative theoretical perspective was explored to redress this problem. Pierre Bourdieu's theoretical concepts of field, capital, and habitus were used to analyze the hierarchical relationships in pediatric acute care hospitals and to design a briefing intervention aimed at improving parents' satisfaction with decision making in that health care setting.

This article examines the relation between the dialectical program established in Plato’s Republic and the practice of dialectic in other dialogues, such as the Parmenides and the Theaetetus. The author argues against those scholars who have sustained a sharp distinction between an intuitive conception of knowledge and the discursive practices characteristic of Plato’s concept of dialectic. In his view, Plato has been overinterpreted from the modern perspective of the distinction between intuitive and discursive forms of knowledge. As a consequence, this (...) article also examines the relation between the dialectical practices displayed in the Parmenides and the Theaetetus and the anhypothetical condition that Plato attributes to “the principle of everything” in the Republic.

Domain experts regularly teach novice students how to perform a task. This often requires them to adjust their behavior to the less knowledgeable audience and, hence, to behave in a more didactic manner. Eye movement modeling examples (EMMEs) are a contemporary educational tool for displaying experts’ (natural or didactic) problem‐solving behavior as well as their eye movements to learners. While research on expert‐novice communication mainly focused on experts’ changes in explicit, verbal communication behavior, it is as yet unclear whether and (...) how exactly experts adjust their nonverbal behavior. This study first investigated whether and how experts change their eye movements and mouse clicks (that are displayed in EMMEs) when they perform a task naturally versus teach a task didactically. Programming experts and novices initially debugged short computer codes in a natural manner. We first characterized experts’ natural problem‐solving behavior by contrasting it with that of novices. Then, we explored the changes in experts’ behavior when being subsequently instructed to model their task solution didactically. Experts became more similar to novices on measures associated with experts’ automatized processes (i.e., shorter fixation durations, fewer transitions between code and output per click on the run button when behaving didactically). This adaptation might make it easier for novices to follow or imitate the expert behavior. In contrast, experts became less similar to novices for measures associated with more strategic behavior (i.e., code reading linearity, clicks on run button) when behaving didactically. (shrink)

While a significant literature has appeared discussing theoretical ethical concerns regarding COVID-19, particularly regarding resource prioritization, as well as a number of personal reflections on providing patient care during the early stages of the pandemic, systematic analysis of the actual ethical issues involving patient care during this time is limited. This single-center retrospective cohort mixed methods study of ethics consultations during the first surge of the COVID 19 pandemic in Massachusetts between March 15, 2020 through June 15, 2020 aim to (...) fill this gap. Results indicate that there was no significant difference in the median number of monthly consultation cases during the first COVID-19 surge compared to the same period the year prior and that the characteristics of the ethics consults during the COVID-19 surge and same period the year prior were also similar. Through inductive analysis, we identified four themes related to ethics consults during the first COVID-19 surge including (1) prognostic difficulty for COVID-19 positive patients, (2) challenges related to visitor restrictions, (3) end of life scenarios, and (4) family members who were also positive for COVID-19. Cases were complex and often aligned with multiple themes. These patient case-related sources of ethical issues were managed against the backdrop of intense systemic ethical issues and a near lockdown of daily life. Healthcare ethics consultants can learn from this experience to enhance training to be ready for future disasters. (shrink)

This article describes some potential uses of Bayesian estimation for time-series and panel data models by incorporating information from prior probabilities (i.e., priors) in addition to observed data. Drawing on econometrics and other literatures we illustrate the use of informative “shrinkage” or “small variance” priors (including so-called “Minnesota priors”) while extending prior work on the general cross-lagged panel model (GCLM). Using a panel dataset of national income and subjective well-being (SWB) we describe three key benefits of these priors. First, they (...) shrink parameter estimates toward zero or toward each other for time-varying parameters, which lends additional support for an income → SWB effect that is not supported with maximum likelihood (ML). This is useful because, second, these priors increase model parsimony and the stability of estimates (keeping them within more reasonable bounds) and thus improve out-of-sample predictions and interpretability, which means estimated effect should also be more trustworthy than under ML. Third, these priors allow estimating otherwise under-identified models under ML, allowing higher-order lagged effects and time-varying parameters that are otherwise impossible to estimate using observed data alone. In conclusion we note some of the responsibilities that come with the use of priors which, departing from typical commentaries on their scientific applications, we describe as involving reflection on how best to apply modeling tools to address matters of worldly concern.

El enigma de la dialéctica platónica se debe a la descripción metafórica de sus procedimientos en la República y a la oscuridad sobre el modo de alcanzar el principio superior que debe dar razón de las hipótesis o supuestos. Como no puede ser derivado deductivamente de otro anterior, algunos especialistas han asignado a la intuición un papel fundamental en su aprehensión, pero esto significaría una dualidad respecto al carácter dialógico de la dialéctica, que conllevaría una ruptura misma del método. Sin (...) embargo, “los peldaños y trampolines” así como el descenso “a partir de las cosas que de él dependen” hablan en favor de un procedimiento netamente discursivo. Esto implica que la dialéctica justifica un supuesto sometido a discusión filosófica por medio de su inclusión en un sistema de proposiciones en las que estas deben estar conectadas de un modo coherente, es decir, sin contradicciones mutuas y en una relación deductiva de anterioridad y posterioridad. En todo este proceso no hay alusión alguna a un método intuitivo, sino una insistencia absoluta en la necesidad de dar razón y de ser capaz de defender el principio afrontando todas las refutaciones u objeciones, que es el procedimiento de donde resulta su condición no hipotética.

En la República Platón parece romper con el intelectualismo socrático al aceptar deseos independientes del bien. Sin embargo, esto no le impide seguir afirmando que el alma hace todo lo que hace en virtud del bien. Para resolver esta aparente contradicción en el presente artículo se insiste en la distinción entre deseos y valores. Los deseos, generados en las partes del alma, están apegados a sus objetos propios, pero los valores revisten estos deseos de imágenes del bien y otros elementos (...) cognitivos que los convierten en móviles aceptables de la acción en la unidad del alma, por lo que hay que distinguir una volición independiente del bien en las partes del alma y una volición que actúa sub specie boni en el contexto de un alma unitaria que ha de decidir entre deseos opuestos entre sí.

Una idea central del presente trabajo es que la unidad del mito con el logos debe comprenderse en la unidad dramática del diálogo platónico. Pero esto no impide distinguir la existencia de dos clases diferentes de discurso: racional y mítico. La escatología no puede abordarse racionalmente por la incertidumbre que hace imposible en este caso el conocimiento del futuro que le está reservado al alma. Esto determina una situación retórica que hace necesaria la clase de persuasión que transmite el mito (...) escatológico. (shrink)

An ethical matrix is a method—or tool—for carrying out an ethical assessment of technology and policy options. This paper describes the ethical matrix method and applies it to the example of GM rape seed. It is argued that added public legitimacy is achieved when the matrix method is used in a participatory process.

It is a mistake to oppose law and grace, for God's grace makes way for a radically transformed social and moral order. The law of Christ enables a new way of life that is obedient to God.

The Tennessee Supreme Court's decision in Davis v. Davis, a case that raises the question of how to allocate frozen embryos in the event of divorce, addresses many of the legal issues posed by in vitro fertilization. The decision considers the interests of the progenitors as well as of the children who may result. For example, the court held that gamete providers' discretion regarding the disposition of embryos can be limited only when their decisions would harm the children who might (...) be born. The court also made clear that efforts to seek genetic parenthood are protected only when accompanied by a desire to raise the resulting children, a conclusion that also affects other reproductive technologies. In addition to elaborating an analytic framework, the court set guidelines for resolving disputes when the couples had made no prior agreements, including holding that while the embryos are ex-utero the desire to avoid genetic parenthood almost always trumps the wish to become a parent. The well-reasoned analysis in Davis v. Davis should help shape legal and ethical discussion regarding the use of in vitro fertilization for many years to come. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Powers of Expression, Expressions of Power: Speech Presentation and Latin LiteratureEllen OliensisAndrew Laird. Powers of Expression, Expressions of Power: Speech Presentation and Latin Literature. Oxford Classical Monographs. Oxford: Oxford University Press, 1999. xx + 358 pp. Cloth, $85.Prospective readers should not be put off by the title of this ambitious book. Though "speech presentation" (the use of direct discourse [DD], free indirect discourse [FID], etc.) may seem a (...) rather narrow and technical topic, Laird makes a persuasive case for its manifold significance. And while he foregrounds "Latin literature," Laird ranges freely across centuries and genres, drawing on texts as diverse as the Hittite SongofUllikummi, Sannazaro's DepartuVirginis, and a 1994 story in the DailyTelegraph. The result is a thoughtful and engaging study from which readers of very different interests and stripes will be able to profit. Three chapters on the theory of narrative representation and speech presentation are followed by another three exploring representational strategies in (mostly Latin) historiography, epic, and the novel; a final chapter treats the speeches of divine messengers in epic as "allegories of representation." The book is framed by a brief introduction and conclusion, the latter capped by a suggestive coda pointing to the multiple lines of research, across various disciplines, which might be opened up by a more scrupulous consideration of speech presentation.In the introduction, Laird outlines the benefits, practical and theoretical, of focusing on speech presentation: "First, [speech presentation] can throw light on the themes and stylistic features of particular texts. Second, functions of speech [End Page 596] presentation bear on broader concerns including form and content, representation, genre, ideology, and intertextuality" (xv). These claims are amply justified in the ensuing chapters. Laird's theoretical orientation generates an abundance of local insights. He suggests that Tacitus' contrasting introductions to the speeches of Calgacus and Agricola--the distancing locutusfertur versus the confident itadisseruit (Agr. 29.4, 33.1)--help differentiate barbarian from Roman by implying "that Agricola's oration possesses a greater ontological stature than Calgacus'" (126); that Encolpius' exploitation of what Laird dubs "angled narration of dialogue" (reserving DD for his interlocutors' speech and ID for his own) produces the effect of narratorial transparency in the Cena (217-20); that the use of direct discourse for Mercury's message and indirect for Fama's in Aeneid 4 "enhances the essential contrast between the nature of the two messengers" (272). In one of his boldest discussions (192-205), Laird reviews the unanswered speeches in the Aeneid and concludes that Virgil's epic is far more rigid than previous epics in associating speech with authority and dutiful silence with subordination (Laird interestingly contrasts Homeric epic, which proclaims this hierarchy but doesn't practice it with anything like Virgil's consistency); Laird goes on to speculate that this strong linkage of speech with authority also applies to Virgil's own epic discourse, which (like Aeneas' narration in books 2 and 3) is delivered to readers who are silent or even silenced.Occasionally, the marriage of theory and interpretation founders. For example, Laird's account of the multiple literary echoes in Encolpius's seaside soliloquy (Satyricon 81.1-82.1, discussed at 221-24) shows little trace of the theoretical self-consciousness displayed in his earlier remarks on the ideological character of intertextuality and its proximity to speech presentation. And the argument that the opening sequence of the Aeneid is designed to entice the reader into Virgil's "realist" fiction (157-64) rests on some unconvincing claims (e.g., that Aeneas' first speech "begins with a prayer" addressed to "the gods, or even the poem's audience" [162], and that Juno's first soliloquy has "the poem's audience or readers" as "her first addressees" [164]). Elsewhere, Laird suggests that Aeneas' parenthetical eloquaransileam? (Aen. 3.39) "could be FID conveying his own doubt and hesitation at the time of the incident he is describing" (182-83); but surely the question makes sense only if it is attached, not to the narrated past (where the relevant question would be "shall I keep pulling on this uncanny tree?") but to the present of narration.Although Laird, an astute reader, has much to teach us about...

Cytoskeletal proteins provide the structural foundation that allows cells to exist in a highly organized manner. Recent evidence suggests that certain cytoskeletal proteins not only maintain structural integrity, but might also be associated with signal transduction and suppression of tumorigenesis. Since the time of the discovery of tensin, a fair amount of data has been gathered which supports the notion that tensin is one such protein possessing these characteristics. In this review, we discuss recent studies that: (1) elucidate a role (...) for tensin in maintenance of cellular structure and signal transduction; (2) implicate tensin as the anchor for actin filaments at the focal adhesion; (3) describe the phosphorylation of tensin; (4) describe potential targets for its Src homology region 2 domain; (5) describe the association between tensin and the nuclear protein p130; and (6) demonstrate that increased tensin expression in a cell line appears to reduce its transformation potential.

Although beef and dairy production in Alberta, Canada, enjoys strong public support, there are enduring public concerns, including farm animal welfare. Evolving codes of practice and animal care councils prescribe changes and improvements to many areas of farm management, and may be seen by farmers as an appropriate response to public animal welfare concerns. However, codes of practice do not address every animal welfare concern, and new concerns can arise over time. Drawing on social practice theory and in-depth field research (...) with 36 cattle and dairy farmers, this paper explores the materials, competencies, and meanings of four animal husbandry practices: branding, dehorning, weaning, and on-farm handling and moving. Findings show that branding and dehorning are evolving slowly with attention to pain management, but remain firmly rooted in ranching tradition and communities of practice. Weaning and animal handling practices are evolving more quickly with attention to changing materials, attitudes, and values that are more prevalent within producer communities. (shrink)

This study examines how businesses manage uncertainty through a combination of emerging technologies, organizational agility, and sustainability practices. Using an integrative literature review and case studies across global regions, the research identifies strategies that enhance decision-making and resilience in volatile environments. The study draws on Dynamic Capabilities Theory and Organisational Information Processing Theory to analyze how companies leverage Big Data, Artificial Intelligence (AI), and Blockchain to navigate uncertainty while ensuring ethical standards. Key findings suggest that firms that adopt flexible organizational (...) structures and sustainable technologies are better positioned to mitigate risks and maintain a competitive edge. Ethical considerations, such as managing algorithmic biases and data privacy, are highlighted as essential for the responsible adoption of these technologies. The study concludes that integrating agility, advanced data analytics, and sustainability not only enhances organizational resilience but also offers long-term strategic advantages. The research provides practical recommendations for business leaders and proposes future research directions focused on SMEs and the ethical implications of digital transformation. (shrink)
