Since K. Fine’s influential criticism of modalism, many philosophers have agreed that we cannot understand the concept of essence with that of modality. However, some philosophers have resisted this mainstream position. In this paper, I examine N. Wildman’s claim that, unlike other versions of modalism, his version of modalism, namely Sparse Modalism can save modalism. I will argue first that if we introduce the notion of grounding into this debates, Wildman’s criticisms of other versions are significantly undermined. Next, I will argue that since Sparse Modalism has an implicit commitment to grounding Wildman cannot blame revising other versions modalism with the concept of grounding. From these claims, I will conclude that the prospect of the success of modalism in general is at best dubious. Without the concept of grounding no version of modalism can succeed and with the concept of grounding no version is well motivated.

This study examined changes in the structural relationship among learner-centred classes perceived by Korean junior high school students, attitudes during class and academic achievement. A linear change model was identified as optimal, showing a steady increase over time for each parameter. The higher the initial value for learner-centred classes, the higher both the initial value and rate of change was for attitudes during class and academic achievement. The initial values for attitudes during class also had a significant effect on initial values of academic achievement, suggesting that attitudes are important in increasing academic achievement. The rate of change of both learner-centred classes and attitudes during class significantly influenced the rate of change of academic achievement.

Here, we achieved significantly enhanced upconversion luminescence in dye-sensitized core/active shell UCNPs via the doping of ytterbium ions in the UCNP shell, which bridged the energy transfer from the dye to the UCNP core. As a result, we synergized the two most practical upconversion booster effectors to amplify upconversion efficiency. We demonstrated two biomedical applications using these UCNPs. By using dye-sensitized core/active shell UCNP embedded poly polymer implantable systems, we successfully shifted the optogenetic neuron excitation window to a biocompatible and deep tissue penetrable 800 nm wavelength. Furthermore, UCNPs were water-solubilized with Pluronic F127 with high upconversion efficiency and can be imaged in a mouse model.

Time distortion in individuals with social anxiety has been defined as the seemingly slower passage of time in social situations and is related to both arousal and valence. Consequently, adaptive behavior is disrupted and interpersonal situations avoided. We explored the effects of valence and arousal on time distortion in individuals with social anxiety. Participants were assigned to two groups, High Anxiety (HA) and Low Anxiety (LA), presented with four types of facial expression stimuli (positive-high arousal, positive-low arousal, negative-high arousal, and negative-low arousal), and asked to estimate the duration of stimulus presentation. Results indicated that, relative to other stimuli, the HA and LA groups perceived longer presentation for high-arousal negative and low-arousal positive stimuli, respectively. These findings suggest that anxious individuals’ time distortion was more severe in situations that evoked high arousal and involved negative emotion.

Managers in ethnic businesses are confronted with ethical dilemmas when taking action based on ethnic ties; and often as a result, they increase the already vulnerable positions of these businesses and their stakeholders. Many of these dilemmas concern the capital that is generated through variations in the use of ethnic stakeholder social ties. The purpose of this paper is to suggest a stakeholder-based model of social capital formation, mediated by various forms of ethnic ties, to explore the duality of ethnicity: it can aid and hinder an ethnic business. Drawing upon the social capital/economic development, stakeholder salience, ethnic businesses literatures, and on social identity theory, we develop a cyclical model of relationships among ethnic business stakeholder attributes and social capital, as mediated by three-way Simmelian bonding and bridging ties, which then, in turn, affects the ethnic stakeholder attributes. We argue that the development of bridging yet strong ties through this cyclical process is relevant for the improvement of the positions of ethnic businesses in terms of both economic success and social responsibility. Specifically, we suggest that, given the duality of ethnicity in business, managers can prioritize stakeholder relationships based upon how these stakeholder ties affect social capital.

This study investigated the time-course characteristics of attentional bias, such as vigilance and maintenance, towards violent stimuli in dating violence (DV) survivors. DV survivors with PTSD symptoms (DV-PTSD group; n=14), DV survivors without PTSD symptoms (Trauma Control group; n=14), and individuals who were never exposed to dating violence (NDV group; n=15) viewed slides that presented four categories of images (violent, dysphoric, positive, and neutral) per slide, for ten seconds. Our results revealed that the DV-PTSD group spent more time on violent stimuli than did the Trauma Control or NDV groups. The DV survivors, both with and without PTSD symptoms, spent more time on dysphoric stimuli and less time on happy stimuli than did the NDV group. In addition to the effects of PTSD, researchers should also be considering the effects of simple traumatic exposure.

As important stakeholder research streams have built their own silos over time, it has become increasingly difficult to visualize a full picture of stakeholder management. To begin to address this gap, we synthesize five distinct stakeholder research streams, which include stakeholder identification, stakeholder understanding, stakeholder awareness, stakeholder prioritization, and stakeholder action. We juxtapose each of these five stakeholder research streams with Scott’s framework consisting of participants, socials structure, environment, technology, and goals of an organization, respectively. What emerges from this analysis of the literature is the notion of “stakeholder work” defined as the purposive processes of an organization aimed at identifying, understanding, being aware of, prioritizing, and acting with respect to stakeholders

Many readers of Plato find it difficult to figure out what the author is really arguing in his works. Unlike other philosophical writing, most of Plato’s works are dialogues, which causes difficulty because Plato does not clearly endorse any one of the characters as his spokesman. In order to overcome this, readers should presumably exercise their own reason when reading Plato’s dialogues in order to find out what the author’s main idea is. In fact, this is exactly what Plato expects from the readers of his dialogues. He does not let his readers sit idly and read passively. Rather, they should carefully and critically analyze his arguments, actively participate in the conversation between the interlocutors, and ..

In this paper, we attempt to refine the concept of corporate citizenship. Traditionally, research on corporate citizenship has paid greater attention to corporateduties, leaving corporate rights relatively unattended in the corporate citizenship literature. However, some scholars have recently explored corporate citizenship as the corporation’s implementation of both of its respected rights and duties. Others have conceptualized the corporate citizenship concept with a specific focus on the corporation’s expansion of its new duties and rights. Integrating existing conceptualizations of corporate citizenship, we propose a refined definition of corporate citizenship as a dynamic process by which corporations implement and expand their respective corporate rights and duties.

Hudson presents a lucid, thoughtful, and convincing account of how Kant's belief in causal determinism is compatible with his belief in human free will. Hudson's book is divided into five largely self contained chapters, the first of which clearly sets forth the apparent conflict. The second chapter is the heart of the book and is also where Hudson is at his best. Hudson brings Kant into contemporary philosophy of mind in the third chapter. The fourth chapter, which is the least crucial for an appreciation of Hudson's central thesis, reconstructs Kant's argument for causal determinism. Hudson concludes with an account of Kant's theory of free will, an account which is surprisingly unsatisfactory in comparison to the rest of the work.
