An examination of the role ofUniversity weed scientists in herbicide efficacyresearch and long-term weed management studies raisesseveral important questions: who should do what kindof research and what kind of research should be done,and, because the university is a research institutionfunded by the public, there is also the importantquestion of who should pay for the research. Indeveloping a response to these questions, severaldimensions of the relationships within which weedscience works must be considered. The author‘sexperience has demonstrated that production, thedominant value (...) in agriculture, provides a sufficientanswer to the questions for many in weed science.However, when weed scientists claim credit forexcellence in production they must also acceptsociety‘s right to hold them responsible for problemsthey now treat as externalities.

I pulled weeds out of half-mile rows of soybeans on grandma and grandpa’s farm long before I heard of the controversy surrounding herbicide resistance and genetic engineering. Twenty years ago, Gordie, Richard, Greg, and I “walked beans,” not knowing that our fists and scythes were not the only means available to Grandpa for killing weeds. We knew little then about uprooting thistles with tractors and discs or about spraying chemicals onto mustard. We knew only that a cool thermos of (...) lemonade and some stem looks from Mom would motivate our troop into action because every good Iowan hated volunteer corn and sunflower shoots. The hatred stemmed as much from the fact that the weeds made a field “look messy from the highway” as from the fact that they cut down yields; Grandma had aesthetic sensibilities as highly developed as any character in Greg Brown’s song.

Risk assessment studies of herbicide resistant sugarbeet have revealed no risks to human health or the environment.Indeed it appears that commercial growth of this crop mightsecure benefits such as decreased pesticide use and increasedbiodiversity. However, widespread resistance to GM crops such asherbicide resistant sugar beet still persists in Europe. It isargued that this is not just because people do not know therelevant facts. Rather it is because popular resistance to GMfood is driven in part by concerns other than the (...) fear ofnarrowly defined risks to health and the environment. These otherconcerns include an aversion to commercial monopoly and anegative view of pesticide use in general. Herbicide resistantsugar beet may also be perceived as a ``Trojan horse,'''' i.e., acrop whose licensing would create a precedent and make it morelikely that other, less environmentally friendly, crops will beapproved within the current strictly technical and science-basedrisk assessment procedures. To meet these public concerns, a kindof technology assessment reflecting factors such as benefits andconsumer choice is called for. (shrink)

Diverse opinion papers related tothe question whether environmental benefits canbe achieved by the herbicide resistancetechnique have been published. But onlylong-term and large-scale field tests usingdifferent weed control methods and additionalagricultural vegetation surveys make itpossible to compare biodiversity effects ofdifferent strategies.

The decline of beneficial plantspecies with all its negative side effects onbiodiversity (...) will continue. Long-termstrategies including improved integratedfarming, managing field boundary structures,and the reintroduction of seed dispersalmechanisms are necessary in order to reversethe trend. (shrink)

The learning process of both students and teachers can be predicted based on the learning mode. Therefore, because of the COVID-19 pandemic, schools must start using online learning and abandon more traditional teaching techniques. Thus, this study investigates the relationship between self-efficacy and academic resilience among 150 senior high school students. Thus, the researchers employed General Self-Efficacy and Resilience Scale. Finally, the statistical analysis reveals that the r coefficient of 0.78 indicates a high positive correlation between the variables. (...) The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between self-efficacy and resilience among senior high school students. (shrink)

This study investigates the relationship between self-efficacy and resilience among 150 first-year college students. This study used a correlational research design.

Examining intrapersonal factors theorized to influence ethics reporting decisions, the relation of self-efficacy as a predictor of propensity for internal whistleblowing is investigated within a US and Canadian multi-regional context. Over 900 professionals from a total of nine regions in Canada and the US participated. Self-efficacy was found to influence participant reported propensity for internal whistleblowing consistently in both the US and Canada. Seasoned participants with greater management and work experience demonstrated higher levels of self-efficacy while gender (...) was also found to be influential to self-efficacy. These individual traits, although related to self-efficacy, did not directly relate to propensities for internal whistleblowing. The findings demonstrate that self-efficacy could represent an important individual trait for examining whistleblowing issues. Internal whistleblowing is becoming an important organizational consideration in many areas of North America, yet there is relatively little research on the topic. Organizations seeking effective internal reporting systems should consider the influence of self-efficacy along with its potential reporting influence. By empirically testing an under-examined component of theory related to internal whistleblowing, this effort contributes to management literature, extending the knowledge beyond a US context, and provides recommendation for managing individual bias with internal reporting systems.

There are several interpretations of the argument structure of Darwin's Origin of Species, representing Covering-Law, Inference-to-the-Best-Explanation, and (more recently) Semantic models. I argue that while all three types of interpretation enjoy some textual support, none succeeds in capturing the overall strategy of the Origin, consistent with Darwin's claim that it is 'one long argument'. I provide detailed criticisms of all three current models, and then offer an alternative interpretation based on the view that there are three main argument strategies in (...) the Origin, all supporting the 'causal efficacy' of Darwin's theory. This interpretation provides both a more unified treatment of the text, and some important implications concerning the relation between general philosophical models of scientific theory support and specific historical cases.

One of the most dynamic areas of plant molecular biology is the investigation of the actions of three classes of herbicides: s‐triazines (atrazine, simazine), glyphosate, and sulfonylureas (chlorsulfuron, sulfometuron methyl) (Figure 1). The results of this work are expected to provide the first significant applications of plant biotechnology: directly, in the genetic engineering of crop plants resistant to specific herbicides and, indirectly, in providing a molecular basis for the rational design of new herbicides for specific biological targets.s‐Triazines affect photosynthesis by (...) inhibiting the binding of quinones to the chloroplast membrane QB protein. An s‐triazine resistant QB protein isolated from weeds in fields consistently treated with the herbicide has a serine in place of a glycine in this highly conserved protein. Glyphosate inhibits 5‐enolpyruvyl‐shikimate‐3‐phosphate synthase (EPSP synthase), an enzyme in the aromatic amino acid biosynthetic pathway. Mutagenized bacteria produce a resistant EPSP synthase with a substitution of serine for proline. Sulfonylureas inhibit the acetolactate synthase (ALS) of bacteria, yeast, and higher plants; this enzyme catalyzes the first step in the synthesis of branched chain amino acids. Resistant ALS has been found in bacteria, yeast and tobacco with a proline substituted by serine in yeast ALS. These findings provide a strong basis for developing projected plant biotechnology applications. (shrink)

The causal impacts of genes and environment on any one biological trait are inextricably entangled, and consequently it is widely accepted that it makes no sense in singleton cases to privilege either factor for particular credit. On the other hand, at a population level it may well be the case that one of the factors is responsible for more variation than the other. Standard methodological practice in biology uses the statistical technique of analysis of variance to measure this latter kind (...) of causal efficacy. In this paper, I argue that: 1) analysis of variance is in fact badly suited to this role; and. (shrink)

Anger is often an appropriate reaction to harms and injustices, but is it a politically beneficial one? Martha Nussbaum (Journal of the American Philosophical Association 1 (1), 41–56, 2015, Anger and Forgiveness. Oxford University Press, 2016) has argued that, although anger is useful in initially recruiting agents for action, anger is typically counterproductive to securing the political aims of those harmed. After the initial shockwave of outrage, Nussbaum argues that to be effective at enacting positive social change, groups and individuals (...) alike, must move quickly out of the state of anger. Feminist theorists (Frye, The Politics of Reality. Crossing Press, 1983; Lorde, 1997; Narayan, Hypatia 3 (2): 31–48, 1988) on the other hand have for long highlighted the efficacy of anger, as well as its moral and epistemic value, in fighting against the oppressive status quo. It might be thought therefore that for political action to be effective, a continued state of anger is preferable. Protestors must after all create and sustain a sense of moral obligation and justice. A main way of doing so is to promote successive moral shocks that trigger outrage (Jasper, Emotion Review 6 (3): 208–213, 2014). I present a novel, empirically informed defense of anger’s efficacy in political action. Nussbaum holds a traditional view on the nature of anger, inherited from Aristotle and the Stoics, which holds that anger constitutively involves a desire for retribution. The view that anger is counterproductive falls out of this and is dominant in academic work as well as in our personal and political lives. Based on work in social psychology, I argue that we need to reconsider this. In doing so, I highlight anger’s aim for recognition, rather than retribution, as key. Furthermore, I uncover conditions for anger’s political efficacy, as well as reasons for why the traditional view of anger has been so pervasive. (shrink)

Background: Chronic Pain (CP) has serious medical and social consequences, and leads to economic burden that threatens the sustainability of healthcare services. Thus, optimized management of pain tools to support CP patients in adjusting to their condition and improving quality of life is timely. Although Acceptance and Commitment Therapy (ACT) is considered an evidence-based psychological approach for CP, evidence for the efficacy of online-delivered ACT for CP is still scarce. At the same time, studies suggest that self-compassion mediates the (...) change in disability and psychopathological symptoms in ACT interventions for CP, although self-compassion is not a specific target in ACT. Thus, an explicit focus on self-compassion might increase the efficacy of ACT interventions for CP, although this hypothesis has not been tested. This study aims to develop an eHealth ACT and compassion-based self-management intervention for CP, the iACTwithPain, and to compare its efficacy in improving health outcomes to a similar ACT-only intervention and a waiting list group. Methods: The eHealth platform that will host the interventions will be developed using a flat design identity and will be interactive. The iACTwithPain intervention will comprise 8 weekly self-management sessions, and will be developed taking into consideration the psychological flexibility model applied to CP, with the addition of explicit compassion-based components. To analyse whether the iACTwithPain intervention will present superiority in improving CP’s impact and related health markers over the two other conditions, this study will follow a RCT design with three arms. CP patients will be recruited through direct contact with patient associations and healthcare services and a national press release in Portugal. Outcome measurement will be conducted at baseline, post-intervention and at 3- and 6-months follow-ups. The interventions’ acceptability will also be assessed. Discussion: The iACTwithPain intervention is expected to improve CP patients’ psychosocial functioning, quality of life, and empowerment, by promoting adaptive disease management and regulation of pain-related internal experiences. Results will contribute to a better understanding on the pertinence of adding compassion elements to ACT for CP and to reach an optimized intervention for CP. (shrink)

Should we continue to support publicly funded research on genetically engineered herbicide resistant crops? In Part One, I discussed the difference between science and ethics, presented a brief history of weed control, and explained three moral principles undergirding my environmentalist perspective. I then argued that unqualified endorsement (E) of the research is unjustified, as is unqualified opposition (O). In Part Two, I argue against qualified endorsement (QE), and for qualified opposition (QO).

Plagiarism is a problematic issue in universities across the globe (Curtis & Vardanega, 2016 ). This study explored the relationship between negative emotionality and positive attitudes toward plagiarism through the mediation of academic self-efficacy and self-control. Negative emotionality was examined as three components: stress, anxiety, and depression. Self-report surveys were completed by 454 university students to investigate the relationship between negative emotionality and positive attitudes toward plagiarism, as well as the mediating role of academic self-efficacy and self-control in (...) this relationship. The hierarchical multiple regression found that negative emotionality significantly predicted positive attitudes toward plagiarism over and above age and gender (i.e., where male students and younger students were more likely to plagiarise). Furthermore, three mediation analyses showed that academic self-efficacy and self-control mediate the relationship between positive attitudes toward plagiarism and each component of negative emotionality. Considering these results, subsequent research should investigate whether implementing strategies that alleviate stress, anxiety, and depression could increase academic self-efficacy and self-control, which in turn, could then reduce positive attitudes toward plagiarism.

ABSTRACT Self-efficacy is the assessment of one’s capacity to perform tasks. Previous research has demonstrated that self-efficacy impacts ethical behavior and attitudes but its effect on ethical cognition and perceptions has not been studied. For the present study, participants analyzed an ethical dilemma after either high or low self-efficacy was induced. Participants analyzed the dilemma using one of two cognitive problem-solving techniques versus a third, control group, and what participants wrote about the problem was content-analyzed to determine (...) how ethical cognition is impacted by self-efficacy. Additionally, perceptions of the ethical problem were examined. Results revealed that differences in self-efficacy did not lead to changes in ethical cognition, but they did lead to changes in perceptions of ethical problems. Implications of these findings are discussed. (shrink)

The controversy over glyphosate-based herbicides, where there is extreme divergences in health and environmental assessments, is rooted in several methodological and normative factors. Foremost among them are the differences found in testing pure glyphosate compared to the testing of glyphosate formulations. The adjuvant chemicals found in formulations can be more toxic than the so-called “active ingredient.” Other factors can also account for why scientists reach different conclusions on the toxicological effects of GBH including the preconceptions and methodological choices they bring (...) into the study. Lack of consensus on the science can be problematic for policymakers. The paper argues that the toxicological science behind the GBH assessments is embedded in a normative substratum, which must be considered in policy decisions. (shrink)

Empirical evidence, it has often been argued, undermines our commonsense assumptions concerning the efficacy of conscious intentions. One of the most influential advocates of this challenge has been Daniel Wegner, who has presented an impressive amount of evidence in support of a model of "apparent mental causation". According to Wegner, this model provides the best explanation of numerous curious and pathological cases of behavior. Further, it seems that Benjamin Libet's classic experiment on the initiation of action and the empirical (...) evidence concerning the confabulation of reason explanations provide further support for this view. In response, I will propose an alternative model of "real mental causation" that can accommodate the empirical evidence just as well as Wegner's. Further, we will see that there is plenty of evidence in support of the assumption that intentions are causally efficacious. This will provide us with ample reason to endorse the model of real mental causation. (shrink)

In her article, Pascale Hess raises the issue of whether her proposed model may be extrapolated and applied to clinical research fields other than stem cell-based interventions in the brain (SCBI-B) (Hess 2012). Broadly summarized, Hess’s model suggests prioritizing efficacy over safety in phase 1 trials involving irreversible interventions in the brain, when clinical criteria meet the appropriate population suffering from “degenerative brain diseases” (Hess 2012). Although there is a need to reconsider the traditional phase 1 model, especially with (...) respect to first-in-human clinical trials involving novel technologies, the question arises as to whether it is appropriate to advocate for a new model that prioritizes efficacy over safety across all phase 1 clinical research trials involving irreversible interventions in the brain. -/- .

This article examines the efficacy of an ethics discernment process in the organizational context, a practice referred to in the paper as "mission due diligence." This type of ethics discernment is a structured process intended to awaken the ethical concerns that a particular issue raises within moral agents and to give voice, directly and indirectly, to those who will be impacted by, and responsible for, strategic decision making. The efficacy of this particular ethics discernment practice is contingent upon (...) several realities, including, but not limited to 1) the timing in which it is undertaken, 2) the degree of importance and relevance attributed to it, and 3) the skills of the person leading it. This case report examines how this process was used to highlight and address the ethical issues related to a new hiring policy, namely, a mandatory nicotine screening test for prospective employees in the healthcare context.

Legal terminology is deemed a key feature of legal discourse and a pivotal constituent of competence evaluation and quality control in the translation of legal texts. Problems of terminology unequivocally prove the need for analysing factors governing changing situations as well as macro-textual parameters and measures for the sake of making strategic decisions at a micro-level. There have been a lack of translation methodology among practitioners and trainees and a lack of a practical operational model that comprises all the primary (...) measures and criteria for analysing translation. The present paper seeks to test the efficacy of the integrative model proposed by Prieto Ramos The Ashgate Handbook of Legal Translation, Ashgate Publishing Limited, Surrey, 2014) in surmounting terminological problems of Arabic-English legal translation through applying the said model to the translation of the three Arabic Islamic legal terms: ‘bayʿu al-tawliya’, ‘bayʿu al-wafāʾi wal-amāna’ and ‘takhliya’ into legal English. The present paper claims that the integrative model proposed by Prieto Ramos The Ashgate Handbook of Legal Translation, Ashgate Publishing Limited, Surrey, 2014) proves useful and fruitful in coping with terminological incongruencies and particularly successful in surmounting problems of rendering legal terms from legal Arabic into legal English. This may be owing to the fact that the said integrative model encompasses all the steps and criteria required for adopting plausible strategic translation decisions. (shrink)

Based on social cognitive theory, we theorize that collective efficacy plays a mediating role in the relationship between paternalistic leadership and organizational commitment and that this mediating role depends on team cohesion. The empirical results from a study of 238 employees from 52 teams at manufacturing companies show that benevolent leadership and moral leadership, both components of paternalistic leadership, are positively related to organizational commitment and further that collective efficacy mediates the moral leadership–organizational commitment relationship. We did not (...) find a relationship between authoritarian leadership and organizational commitment. Besides, it was found that team cohesion negatively moderates the relationship between moral leadership and collective efficacy and positively moderates the relationship between collective efficacy and organizational commitment. Explanations and directions for future research are discussed. (shrink)

BackgroundAcrophobia is a specific phobia characterized by a severe fear of heights. The purpose of the present study was to investigate the efficacy of two therapies that may ameliorate symptoms of acrophobia and anxiety sensitivity, i.e., virtual reality exposure therapy (VRET) and eye movement desensitization and reprocessing (EMDR) therapy with a Waiting List Control Condition (WLCC).MethodsWe applied a three-armed randomized controlled pre-post-test design with 45 female adolescent students. Students who met DSM-5 criteria for acrophobia were randomly assigned to either (...) VRET (N = 15;Mage = 17.26; SD = 1.32), EMDR (N = 15;Mage = 17.15; SD = 1.57), or a WLCC (N = 15;Mage = 17.50; SD = 1.26). The study groups were evaluated one week before the intervention and one week after the last intervention session regarding symptoms of acrophobia (Severity Measure for Acrophobia) and anxiety sensitivity (Anxiety Sensitivity Index).ResultsThe data showed that both the application of VRET and EMDR therapy were associated with significantly reduced symptoms of acrophobia (d = 1.03 for VRET and d = 1.08 for EMDR) and anxiety sensitivity (d = 1.15 for VRET and d = 1.13 for EMDR) in comparison to the Waiting List.LimitationsThe sample consisted only of adolescent women. Due to the recognizable differences between the two interventions, the therapists and the participants were not blind to the conditions.ConclusionThe results suggest that both VRET and EMDR are interventions that can significantly improve symptoms of acrophobia and anxiety sensitivity in female adolescents.Clinical Trial Registrationhttps://www.irct.ir/trial/57391, identifier: IRCT20210213050343N1.

The transition from university to working life appears a critical period impacting human service workers’ long-term health. More research is needed on how psychological factors affect the risk. We aimed to investigate how subgroups, based on self-efficacy, psychological flexibility, and basic psychological needs satisfaction ratings, differed on self-rated health, wellbeing, and intention to leave. A postal survey was sent to 1,077 recently graduated psychologists in Sweden, response rate 57.5%, and final sample 532. A hierarchical cluster analysis resulted in a (...) satisfactory eight-cluster solution. We identified two at-risk subgroups, displaying the lowest scores on health and wellbeing, and one potential low-risk subgroup with the highest ratings on said variables. The “Low risk?” group rated high on all three psychological constructs, a positive transition to working life, a work environment where resources balanced relatively high emotional demands, good health, and wellbeing. Almost the complete opposite ratings characterized the potential risk groups. “Quitting?” scored significantly higher than “Getting sick?” on self-efficacy and psychological flexibility as well as actively seeking new employment and reporting daily thoughts on leaving the profession. We suggest that a combination of low self-efficacy and psychological flexibility could increase the risk of individuals staying despite suboptimal working conditions. With combined higher self-efficacy and psychological flexibility, individuals in similar circumstances appear more inclined to quit. We conclude that the ways recently graduated psychologists rate their self-efficacy, psychological flexibility, and basic needs satisfaction appear to be reflected in their self-rated health and wellbeing.

To maximize brain plasticity after stroke, several rehabilitation strategies have been explored, including the use of intensive motor training, motor imagery, and action observation. Growing evidence of the positive impact of virtual reality (VR) techniques on recovery following stroke has been shown. However, most VR tools are designed to exploit active movement, and hence patients with low level of motor control cannot fully benefit from them. Consequently, the idea of directly training the central nervous system has been promoted by utilizing (...) motor-imagery (MI) based brain-computer interfaces (BCIs). To date, detailed information on which VR strategies lead to successful functional recovery is still largely missing, and very little is known about how to optimally integrate BCI and VR paradigms for stroke rehabilitation. The purpose of this study was to examine the efficacy of a BCI-VR system using a MI paradigm for post-stroke upper limb rehabilitation on functional assessments, and related changes in MI ability and brain imaging. To achieve this, a 60 years old male chronic stroke patient was recruited. The patient underwent a 3-week intervention in a clinical environment, resulting in 10 BCI-VR training sessions. The patient was assessed before and after intervention, as well as on a one-month follow-up, in terms of clinical scales and brain imaging using functional MRI (fMRI). Consistent with prior research, we found important improvements in upper extremity scores (Fugl-Meyer) and identified increases in brain activation measured by fMRI that suggest neuroplastic changes in brain motor networks. This study expands on the current body of evidence as more data are needed on the effect of this type of interventions not only on functional improvement but also through brain imaging to study the effect of the intervention on plasticity.

Several philosophers have argued recently that semantic properties do play a causal role. 1 It is our view that none of these arguments are satisfactory. Our aim is to reveal some of the deficiencies of these arguments, and to reassess the question in our own way. In section 1, we shall explain in more detail what is involved in the pretheoretical idea of a causally efficacious property and so provide a fuller sense of the issue. In section 2 we shall (...) discuss Fodor's and Kim's arguments that the semantic properties of mental events are causally efficacious. Their tactic is to articulate sufficient conditions for the causal efficacy of a property, and then apply these conditions to the psychological properties under consideration. We shall show that both formulations are inadequate. However, each account can remedy some of the defects of the other. We shall argue that by putting the two together, and modifying this combined account in certain ways, we can arrive at something that might just pass as a general sufficient condition for causal efficacy. We believe that the question of causal efficacy of content is best approached as a question in the philosophy of science. If one wants to know whether a given species of property is efficacious, the most productive strategy is to find a science that investigates the properties and examine the role they are assigned. In keeping with this attitude we shall restrict our discussion to the notion of content deployed within cognitive science. In section 3 we examine the role of content in cognitive science and discuss whether this role suits content to the conditions on efficacy articulated in section two. Our conclusion will be conditional and hedged: on certain views of cognitive science, content will meet the sufficient condition for efficacy. If other views are correct, the question remains open.

Aversive autobiographical memories sometimes prompt maladaptive emotional responses and contribute to affective dysfunction in anxiety and depression. One way to regulate the impact of such memories is to create a downward counterfactual thought–a mental simulation of how the event could have been worse–to put what occurred in a more positive light. Despite its intuitive appeal, counterfactual thinking has not been systematically studied for its regulatory efficacy. In the current study, we compared the regulatory impact of downward counterfactual thinking, temporal (...) distancing, and memory rehearsal in 54 adult participants representing a spectrum of trait anxiety. Participants recalled regretful experiences and rated them on valence, arousal, regret, and episodic detail. Two to six days later, they created a downward counterfactual of the remembered event, thought of how they might feel about it 10 years from now, or simply rehearsed it. A day later, participants re-rated the phenomenological characteristics of the events. Across all participants, downward counterfactual thinking, temporal distancing, and memory rehearsal were equally effective at reducing negative affect associated with a memory. However, in individuals with higher trait anxiety, downward counterfactual thinking was more effective than rehearsal for reducing regret, and it was as effective as distancing in reducing arousal. We discuss these results in light of the functional theory of counterfactual thinking and suggest that they motivate further investigation into downward counterfactual thinking as a means to intentionally regulate emotional memories in affective disorders.

Let’s consider the following paradox (Fodor [1989], Jackson and Petit [1988] [1992], Drestke [1988], Block [1991], Lepore and Loewer [1987], Lewis [1986], Segal and Sober [1991]): i) The intentional content of a thought (or any other intentional state) is causally relevant to its behavioural (and other) effects. ii) Intentional content is nothing but the meaning of internal representations. But, iii) Internal processors are only sensitive to the syntactic structures of internal representations, not their meanings. Therefore it seems that if we (...) want to defend the idea -absolutely plausible from an intuitive point of view- that mental / intentional states are causally responsible for behavioural outputs and we want to do it on the physicalist basis of any scientific methodology, we will have to give up the conviction that such intentional states qua intentional, i. e. as having a particular meaning, are the ones causally responsible for our behaviour. The path that takes us to mental epiphenomenalism is clear: 1) the causal powers of any event are completely determined by its physical properties; 2) although intentional properties supervene on physical properties, they can’t be identified with them; 3) intentional properties, as intentional, are not causally responsible for behaviour, because they don’t take part in the causal powers of the states to which they belong, i. e., intentional properties are epiphenomenal. Let’s consider now a different yet parallel position to the one just described. There is an important debate in cognitive science about whether the class of mechanisms to which we belong and which the computational modelling project of cognitive processes refers to is best represented by classical or connectionist approaches (McClelland, Rumelhart et. al [1986], Smolensky [1987] [1988], Fodor and Pylyshyn [1988], Pinker and Prince [1988], Clark [1989], Ramsey, Stich and Rumelhart [1991], Clark and Karmiloff-Smith [forthcoming]).In classical, serial processing models, information is encoded in terms of rules that have a linguistic character. In connectionist or parallel distributed processing (PDP) models, the causal relationships among the units that constitute the system determine how the information is processes by the network, although these units don’t have a direct semantic interpretation. But, for both, classical and connectionist models, all the computations can be explained without any reference to the content of the processed information, i.e., in both cases the properties that seem to be responsible for the system’s behaviour are ultimately physical properties nor intentional ones. This situation mirrors thus, within cognitive science, the philosophical discussion concerning the causal efficacy of semantic properties. Now, if in this debate we opt for the classical paradigm, there is a way of finding a solution to the computational version of the epiphenomenalism paradox. This solution is based mainly on the notion of supervenience or, more precisely, on the notion of mereological supervenience (Kim [1984] [1988])1 . The idea of intentional properties supervening on physical properties makes sense within the classical context because there exists an easily isolable supervenience base comprising the syntactic items in the socalled language of thought. But, what happens if we opt for the connectionist paradigm?. The situation here doesn’t seem to favour the use of the same supervenience strategy. For it has been argued (Ramsey, Stich and Garon [1991]) that beliefs, desires, and other mental states are nor, in the connectionist paradigm, individuable as weight or activation states of the system. This is because information is encoded by the network in distributed and superpositional representations, i.e., there are no straightforwardly isolable vehicles at the physical level that can be identified as the articulated supervenience base on which the semantic properties supervene2 . If this is true, then the connectionist not only loses the battle against epiphenomenalism but more drastically, seems to offer a standing invitation to eliminativism, since talk of beliefs and desires, etc. now seems to be floating free of any acceptable scientific underpinning, i.e., she has lost the necessary theoretical apparatus for supporting the intuitive idea that propositional attitudes -beliefs, desires and any mental states with semantic content- are physically realized. This second line of argumentation doesn’t take us to a paradox but to a dilemma: either we accept eliminativism, if connectionist hypothesis are correct or we defend the causal efficacy of mental states with semantic content by showing that, after all, connectionist networks are not plausible cognitive models (Davies [1991]). From my point of view, however, both lines of argumentation need to be revised. The aim of this paper is to find an account of the causal efficacy of content that avoids the aforementioned epiphenomenalist objections and that doesn’t require the discovery of inner symbols in the computational modelling of such contentful mental states. In short, the aim is to find a meeting point where a philosophical story about content and cause and the connectionist computational model can be brought together (Cfr. Clark [1989]). (shrink)

PurposeSelf-efficacy has been argued theoretically and shown empirically to be an essential construct for students’ improved learning outcomes. However, there is a dearth of studies on its causal effects on performance in mathematics among university students. Meanwhile, it will be erroneous to assume that results from other fields of studies generalize to mathematics learning due to the task-specificity of the construct. As such, attempts are made in the present study to provide evidence for a causal relationship between self-efficacy (...) and performance with a focus on engineering students following a mathematics course at a Norwegian university.MethodThe adopted research design in the present study is a survey type in which collected data from first-year university students are analyzed using structural equation modeling with weighted least square mean and variance adjusted estimator. Data were generated using mainly questionnaires, a test of prior mathematics knowledge, and the students’ final examination scores in the course. The causal effect of self-efficacy was discerned from disturbance effects on performance by using an innovative instrumental variable approach to structural equation modeling.ResultsThe findings confirmed a significant direct effect of the prior mathematics knowledge test on self-efficacy, a significant direct effect of self-efficacy on performance, and a substantial mediating effect of self-efficacy between a prior mathematics knowledge test and performance. Prior mathematics knowledge and self-efficacy explained 30% variance of the performance. These findings are interpreted to be substantial evidence for the causal effect of self-efficacy on students’ performance in an introductory mathematics course.ConclusionThe findings of the present study provide empirically supports for designing self-efficacy interventions as proxies to improve students’ performance in university mathematics. Further, the findings of the present study confirm some postulates of Bandura’s agentic social cognitive theory. (shrink)

The strict lockdown experienced in Spain during March–June 2020 as a consequence of the COVID-19 crisis has led to strong negative emotions. Music can contribute to enhancing wellbeing, but the extent of this effect may be modulated by both personal and context-related variables. This study aimed to analyze the impact of the two types of variables on the perceived efficacy of musical behaviors to fulfill adults’ emotional wellbeing-related goals during the lockdown established in Spain. Personal variables included age, gender, (...) musical training, personality, resilience, and perception of music’s importance. Contextual variables referred to living in a region with a high COVID-19 impact, perception of belonging to a risk group, being alone, having caring responsibilities during confinement, and amount of time of music listening as compared to prior to the crisis. The study was conducted retrospectively during August–December 2020, when the strict lockdown was over in Spain. An online survey was disseminated among the general population and groups of musicians, and the answers of 507 adults were analyzed. Only personal, but not COVID-19 context-related variables, showed an impact on music’s efficacy. The youngest age group of adults and those with musical training reported the highest efficacy of music for wellbeing enhancement, and music’s importance was found to be the main significant predictor of music’s perceived efficacy. Our findings suggest that the people who have been reported to be emotionally more vulnerable during the lockdown, due to either a strong impact on their daily lives or their lower resilience, perceive a higher benefit from musical behaviors. Being musically trained, even for a small number of years, also leads to a perception of higher efficacy of music for the achievement of emotional wellbeing goals. However, this effect is explained by the musically trained individuals’ higher perception of music’s importance. Although musical behaviors can be generally considered as important for wellbeing enhancement, our study highlights who are the potential individuals who could benefit the most from music-related activities for obtaining better levels of wellbeing, at least within the current context of the COVID-19 crisis.

BackgroundAt present, tic disorder has attracted the attention of medical researchers in many countries. More clinicians choose non-drug therapy, especially cognitive-behavioral therapy because of the cognitive side effects of drug therapy. However, few studies had assessed its efficacy. It is necessary to have a more comprehensive understanding of the literature quality of CBT and its intervention effect.MethodsIn this study, MEDLINE, Embase, and Cochrane were searched from the beginning to June 15, 2021 to study the efficacy of -CBT on (...) tic disorder. Only studies using the Yale Global Tic Severity Scale and the control group were included.ResultsA total of 12 randomized controlled trials, including 536 patients with tic disorders, were identified. The results showed that the effect of CBT was better than that of the control group. The pooled standardized mean difference was −0.34. The effect size of CBT differs from different intervention conditions. In seven studies, the subjects’ motor tic scores were counted. The sample size of the experimental group was 224 and that of the control group was 218. The pooled SMD was −0.43. Seven studies counted the vocal tic scores of subjects, 224 in the experimental group and 218 in the control group. The pooled SMD was −0.22. Seven studies counted the tic impairment scores of subjects, 220 in the experimental group and 214 in the control group. The pooled SMD was −0.48.ConclusionThe literature shows that different CBTs can significantly reduce the total score of tic disorder and the score of motor tic, but cannot significantly reduce the score of vocal tic. In the future, more new interventions were needed to improve the symptoms of different patients, especially vocal tic. (shrink)

: The purpose of this paper is to highlight some difficulties of Neil Sinhababu’s Humean theory of agency, which depend on his radically reductivist approach, rather than to his Humean sympathies. The argument is that Sinhababu’s theory builds upon a critique of reflective agency which is based on equivocation and misunderstandings of the Kantian approach. Ultimately, the objection is that his reductivist view is unequipped to address the rclassical problems of rational deliberation and agential authority. Keywords: Humean Theory; Rational Deliberation; (...) Agency; Authority; Christine Korsgaard Efficacia riflessiva Riassunto: Questo articolo mette in luce alcune difficoltà della teoria proposta da Neil Sinhababu, che dipendono daun approccio radicalmente riduttivista. Si argomenta che la teoria di Sinhababu è basata su alcuni fraintendimenti a proposito dell'approccio kantiano alla teoria dell'azione. L'obiezione fondamentale è che questa posizione riduttivista non riesce a rendere conto adeguatamente della deliberazione razionale e dell'autorità dell'agente. Parole chiave: Teoria humeana; Deliberazione razionale; Agentività; Autorità; Christine Korsgaard. (shrink)

ABSTRACT“A legal system exists,” Joseph Raz claims, “if and only if it is in force.” By this he means to suggest that the efficacy of law—that is, its capacity to control the population to which it applies—is necessary for its identity as such. Despite widespread recognition that efficacy is a condition of the existence of law, however, little time has been spent analyzing the notion. This article begins an attempt to make up the deficit. I make the case (...) for efficacy as necessary for law and go on to develop and defend an account of the concept that is broadly Kelsenian in spirit. In doing so I address questions concerning the relationship between obedience and enforcement in an account of the existence of a legal system as well as relating the discussion to that concerning the ontological status of international law.
