This paper aims to address the difficulties of high school students in bridging their computational understanding with their visualization skills in understanding the notion of the limits in their calculus class. This research used a pre-experimental one-group pretest-posttest design research on 62 grade 10 students enrolled in the Science, Technology, and Engineering Program (STEP) in one of the public high schools in Zamboanga del Sur, Philippines. A series of remedial sessions were given to help them understand the function values, one-sided (...) limits, limits of a function, and its discontinuities with the aid of the GeoGebra. Results revealed that there is a significant improvement in their mathematics performance before and after the remediation, t(61) = -19.99, p<.05. The real-time feedback provided by the drawing interface of GeoGebra has provided the students the insights into how objects behave in geometrical space, bridging their understanding in locating the values shown by the computational algebraic processes. Additionally, the significant difference in the achievement reveals a large effect size (Cohen’s =2.54) which could be accounted for by the remediation using interactive activities in the GeoGebra.

The objective of the study was to develop a structural model that explores the relationship between Mathematics Performance and students’ self-regulated learning skills, grit, and expectancy-value towards science, technology, engineering and mathematics (STEM). The research collected survey data from 664 senior high school students from 17 STEM high schools, and conducted a covariance-based structural equation modeling (SEM) analysis. The results of the SEM analysis indicate that the Re-specified Self-Regulated Learning Skill – Expectancy-Value towards STEM – Grit – Mathematics Performance (Re-specified (...) SRL-EV-GR-MP) model is the most parsimonious fit, offering the best empirical support for the theoretical model of the study. The research findings suggest that the mathematics performance of senior high school students in STEM curriculum is attributed to their high expectancies for success and perceived values of the STEM tasks, high grit, and high self-regulated learning skills. Moreover, the research also observed evidence of mediating and moderating grit effects in the concurrent effects of expectancy-values towards STEM and self-regulated learning skills towards students’ mathematics performance.

Max Weber's distinction in "Politics as a Vocation" between the ethic of conviction and the ethic of responsibility is best understood as a distinction between mutually exclusive ethical worldviews. Interpretations that correlate the two ethics with Weber's distinction between value-rational social action and instrumental-rational social action are misleading since Weber assumes that both types of rational social action are present in both ethics. The ethic of conviction recognizes a given hierarchy of values as the context for moral endeavor. The ethic (...) of responsibility acknowledges value obligations, but assumes the absence of any given hierarchy of values and the inevitability of value conflict as the context for moral endeavor. When interpreted in the context of his multilayered understanding of value conflict, Weber's ethic of responsibility emerges as a coherent ethical perspective. (shrink)

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

Joann Starr, a Roman Catholic nun, and Bruce Zawacki, a burn surgeon, met 22 years ago in the Los Angeles County, University of Southern California Burn Center in the roles of a patient and her physician struggling over issues of autonomy and informed consent. After recovery, she remained a nun and has become a patient advocate and doctoral candidate in bioethics. He remained a burn surgeon and has become a bioethics teacher and author. Although they live in distant locations, (...) they maintain their friendship and frequently discuss their shared experience. Recently they met to reflect on the events, lessons, and meanings of their original encounter. (shrink)

Imperative sentences like Dance! do not seem to represent the world. Recent modal analyses challenge this idea, but its intuitive and historical appeal remain strong. This paper presents three new challenges for a non-representational analysis, showing that the obstacles facing it are even steeper than previously appreciated. I will argue that the only way for the non-representationalist to meet these three challenges is to adopt a dynamic semantics. Such a dynamic semantics is proposed here: imperatives introduce preferences between alternatives. This (...) characterization of meaning focuses on what function a sentence serves in discourse, rather than what that sentence refers to (e.g., a state of the world). By representing the meaning of imperatives, connectives and declaratives in a common dynamic format, the challenges posed for non-representationalism are met. (shrink)

Utterances of natural language sentences can be used to communicate not just contents, but also forces. This paper examines this topic from a cross-linguistic perspective on sentential mood. Recent work in this area focuses on conversational dynamics: the three sentence types can be associated with distinctive kinds of conversational effects called sentential forces, modeled as three kinds of updates to the discourse context. This paper has two main goals. First, it provides two arguments, on empirical and methodological grounds, for treating (...) sentential force as part of a compositional dynamic semantics, rather than a dynamic pragmatics. Second, it formulates a minimal dynamic semantic analysis that covers the data at the heart of these arguments, incorporating existing analyses of the three major moods, evidentials and conjunction. A further aim of the paper is to sharpen the distinction between sentential force and utterance force, and discuss its implications. (shrink)

This study developed an instrument that measures the attitude of Filipino high school students towards mathematics, with reliable predictors and factors. Using the responses of 300 high school students from Zamboanga Sibugay, the validity and reliability of the Mathematics Attitude Scale (MAS) was tested using Exploratory Factor Analysis (EFA) and reliability analyses. The EFA showed that four-factor structures of the instrument, regarding the mathematics attitude for high school students, explained 27.48% of the variance in the pattern of relationships among the (...) items. The Average Variance Extracted (AVE), Composite Reliability, and Cronbach’s Alpha coefficients were reported. They proved that the extracted constructs have obtained and satisfied convergent validity. Thirty-three items remained in the final questionnaire after deleting the twenty-seven items with factor loadings of less than 0.4 (Students’ Perceived Motivation and Support in Learning Mathematics: twelve items; Students’ Perceived Anxiety in Learning Mathematics: ten items; Students’ Perceived Self-Efficacy in Learning Mathematics: six items; and Teachers and Parents’ Influences to Students in Learning Mathematics: five items). This study has confirmed the four-factor structure of the MAS. Educators and researchers can use the MAS to better understand the attitudes of Filipino high school students towards mathematics.

How does the body influence the way we see the world? _Imagination, Illness and Injury_ examines the psychological factors behind perceptual limitations and distortions and links a broad range of somatic manifestations with their resolution. Melanie Starr Costello applies Jungian theory to a variety of cases, attributing psychosomatic phenomena to cognitive processes that are common to us all. She analyses the role of illness in several life narratives, and interprets the appearance of somatic phenomena during important phases of analytic (...) treatment. Together these case narratives present a significant challenge to established views of psychosomatics. Subjects covered include: archetypal constrictions of identity somatic elements of perception the psyche-soma split. _Imagination, Illness and Injury _brings a fresh perspective to the understanding and treatment of the psychotherapy client as a psycho-somatic unity. Jungian analysts, psychoanalysts, and psychotherapists will greatly benefit from the clinical applications of archetypal theory presented here. (shrink)

A photographer and a geographer explore where the pavement ends. Nevada's enigmatic Black Rock country, despite its apparent silence and isolation, is actually an area where natural forces are ceaselessly restless and life in many forms has endured for millennia. Its haunting landscape has been the focus of study and contemplation by scientists, explorers, outdoors aficionados, and artists. In ""Black Rock,"" photographer Peter Goin and geographer Paul F. Starrs explore this fascinating place from the viewpoints of their respective disciplines. The (...) Black Rock, a desert realm almost the size of Delaware but scarcely a hundred miles north of Reno, embraces mile-high vertical mountains and one of the earth's flattest, most barren salt pans, boiling hot springs and freezing winter cold, plants that have evolved to survive the severest drought and lush pockets of rich grasses. Its bewildering environments startle our senses with a raw physical intensity that comes through in Goin's eloquent photographs and Starrs's richly informed text. We observe the region from numerous perspectives - the Black Rock at ground level, from the skies above, in the geology below; witness the shaping roles of water, wind, and geothermal action in shaping it; and view the effects of human hands, from ancient Native Americans to nineteenth-century explorers, ranchers, and miners, up through the congregants at today's Burning Man festivals. The result is a brilliant duet of visual and literary commentary on a region of stunning paradoxes and constant change and activity, where need and curiosity encounter the daunting, implacable forces of nature.

Large deletions and genomic re‐arrangements are increasingly recognized as common products of double‐strand break repair at Clustered Regularly Interspaced, Short Palindromic Repeats ‐ CRISPR associated protein 9 (CRISPR/Cas9) on‐target sites. Together with well‐known off‐target editing products from Cas9 target misrecognition, these are important limitations, that need to be addressed. Rigorous assessment of Cas9‐editing is necessary to ensure validity of observed phenotypes in Cas9‐edited cell‐lines and model organisms. Here the mechanisms of Cas9 specificity, and strategies to assess and mitigate unwanted effects (...) of Cas9 editing are reviewed; covering guide‐RNA design, RNA modifications, Cas9 modifications, control of Cas9 activity; computational prediction for off‐targets, and experimental methods for detecting Cas9 cleavage. Although recognition of the prevalence of on‐ and off‐target effects of Cas9 editing has increased in recent years, broader uptake across the gene editing community will be important in determining the specificity of Cas9 across diverse applications and organisms.

Domestic violence is endemic across Latin America. It is legitimated by patriarchal Christian theologies and widespread gender inequality. Drawing on the work of women theologians and activists working in Argentina, Uruguay and elsewhere, this article explores women's networks of resistance against violence. These include public and legal acknowledgement of domestic violence; the transmission of life-affirming values; pastoral support in the denouncement of violence; and the development of open and fluid household structures.

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)

This paper proposes a semantics for free choice permission that explains both the non-classical behavior of modals and disjunction in sentences used to grant permission, and their classical behavior under negation. It also explains why permissions can expire when new information comes in and why free choice arises even when modals scope under disjunction. On the proposed approach, deontic modals update preference orderings, and connectives operate on these updates rather than propositions. The success of this approach stems from its capacity (...) to capture the difference between expressing the preferences that give rise to permissions and conveying propositions about those preferences.

_Reasonable Risk_ examines the concept of risk as it applies to everyday life in general and to alcohol consumption specifically. The book addresses how we assess risks, and the strategies we use to manage them. It examines the elements that shape our perceptions of risk-cultural influences, social factors, and how we are presented with information about risk. The final chapter of the book focuses on the role of risk in policy formulation, examining in particular how alcohol policies are developed within (...) the context of individual and societal responsibility.

No existing conditional semantics captures the dual role of 'if' in embedded interrogatives — 'X wonders if p' — and conditionals. This paper presses the importance and extent of this challenge, linking it to cross-linguistic patterns and other phenomena involving conditionals. Among these other phenomena are conditionals with multiple 'if'-clauses in the antecedent — 'if p and if q, then r' — and relevance conditionals — 'if you are hungry, there is food in the cupboard'. Both phenomena are shown to (...) be problematic for existing analyses. Surprisingly, the decomposition of conditionals needed to capture the link with interrogatives provides a new analysis that captures all three phenomena. The model-theoretic semantics offered here relies on a dynamic conception of meaning and compositionality, a feature discussed throughout. (shrink)

Environmental ethics is the subject in philosophy that examines the moral relationship of human beings to the environment and its non-human species. It concerns human’s ethical relationship with the natural environment. The central question concerning environmental ethics is essentially – what is human being’s moral obligation concerning the natural environment? The paper will firstly provide a review of the ethical relations of humans and the environment, secondly examine how value-based education can assist in inculcating environmental ethics among learners.

Rationale, aims and objectives To compare the pharmacotherapeutic approaches to diabetic hypertension of family physicians (FPs) and general practitioners (GPs). Methods A retrospective prescription-based study was conducted in 15 out of a total of 20 health centres, involving 115 primary care physicians – 77 FPs and 38 GPs, representing 74% of the primary care physicians of Bahrain. Prescriptions were collected during May and June 2000 to comprise a study population of 1266 diabetic-hypertensive patients. Results As monotherapy, angiotensin-converting enzyme (ACE) inhibitors (...) (37.9%) and β-blockers (38.3%) were the most commonly prescribed classes of antihypertensives by FPs and GPs, respectively. Calcium channel blockers (CCBs) were ranked third by both categories of physicians. For two-drug combinations, a β-blocker and an ACE inhibitor was the combination of choice for both physician categories. Patients managed by the FPs were more likely to receive a β-blocker–CCB combination (17.4 vs. 14.9%) or a diuretic–ACE inhibitor combination (16.7 vs. 11.4%) and less likely to receive a β-blocker–diuretic combination (11.8 vs. 16.7%) than those managed by the GPs. The proportion of patients receiving antihypertensive combinations was 40.6 and 38.5% for FPs and GPs, respectively. While the GPs prescribed CCB as a monotherapy to the elderly most often, the FPs choice was a β-blocker. Diuretics were less preferred by both FPs and GPs. β-Blocker–ACE inhibitor was again the most preferred combination of both FPs and GPs. FPs prescribed CCB–β-blocker combinations more often than GPs (P = 0.01), whereas CCB–ACE inhibitor combinations were less preferred (P = 0.09). A trend towards excessive use of short-acting nifedipine as monotherapy for elderly patients, both by FPs and by GPs, was noticed. Glibenclamide, alone or in combination with metformin, was the foremost antidiabetic drug prescribed by FPs and GPs. Middle-aged (45–64 years) patients seen by GPs were more likely to receive glibenclamide than those treated by FPs (P = 0.001) and less likely to receive gliclazide (P = 0.01). Combinations of a β-blocker with either glibenclamide or insulin were prescribed considerably more often by GPs.Conclusions Within the same practice setting, a substantial difference was observed between FPs and GPs in terms of preference for different classes of drugs in the management of diabetic hypertension. The compliance of both FPs and GPs was suboptimal; overall, the compliance of the FPs was closer to the recommended guidelines, however. Educational programmes should specifically address these inadequacies in order to improve the quality of health care. (shrink)

This work explores the hypothesis that natural language is a tool for changing a language user's state of mind and, more specifically, the hypothesis that a sentence's meaning is constituted by its characteristic role in fulfilling this purpose. This view contrasts with the dominant approach to semantics due to Frege, Tarski and others' work on artificial languages: language is first and foremost a tool for representing the world. Adapted to natural language by Davidson, Lewis, Montague, et. al. this dominant approach (...) has crystalized as truth-conditional semantics: to know the meaning of a sentence is to know the conditions under which that sentence is true. Chapter 1 details the animating ideas of my alternative approach and shows that the representational function of language can be understood in terms of the more general function of changing representational mental states. Chapters 2-4 argue that the additional resources of this more general conception of meaning allow us to explain certain phenomena involving conditionals and grammatical mood that truth-conditional semantics does not. In the analysis of these specific phenomena and the articulation of the general approach on offer, it emerges that this approach combines insights and benefits from both use-theoretic and truth-theoretic work on meaning.
