A simple 5-DoF MR-compatible motion signal measurement system

The purpose of this study was to develop a simple motion measurement system with magnetic resonance (MR) compatibility and safety. The motion measurement system proposed here can measure 5-DoF motion signals without deteriorating the MR images, and it has no effect on the intense and homogeneous main magnetic field, the temporal-gradient magnetic field (which varies rapidly with time), the transceiver radio frequency (RF) coil, and the RF pulse during MR data acquisition. A three-axis accelerometer and a two-axis gyroscope were used to measure 5-DoF motion signals, and Velcro was used to attach a sensor module to a finger or wrist. To minimize the interference between the MR imaging system and the motion measurement system, nonmagnetic materials were used for all electric circuit components in an MR shield room. To remove the effect of RF pulse, an amplifier, modulation circuit, and power supply were located in a shielded case, which was made of copper and aluminum. The motion signal was modulated to an optic signal using pulse width modulation, and the modulated optic signal was transmitted outside the MR shield room using a high-intensity light-emitting diode and an optic cable. The motion signal was recorded on a PC by demodulating the transmitted optic signal into an electric signal. Various kinematic variables, such as angle, acceleration, velocity, and jerk, can be measured or calculated by using the motion measurement system developed here. This system also enables motion tracking by extracting the position information from the motion signals. It was verified that MR images and motion signals could reliably be measured simultaneously.     

An Apology for a Religion of the Melancholic

This article is a study of depression and melancholia from the psychoanalytic perspective. Starting with the issue of levels and categories involving the phenomena of depression and melancholia, it elucidates the particular nature of the melancholic loss; the fact that the melancholic’s problem has to do with language; the view of the melancholic subject as a default subject; and the question of desire in melancholia and its trajectory toward recovery, eventually leading to a hopeful imagination concerning the innermost human desire. Three Lacanian psychoanalytic theories (Darian Leader (2009); Colette Soler (2006); Slavoj Zizek (2006)) are used to support my arguments; Suah Bae (2003, 2004) provides fascinating fictional truths that witness to the melancholic’s inner world; and Donald Capps (2000) renders a decisive help in my pastoral psychological reading of all of these writers.     

Multiple Roles of Married Korean Women: Effect on Depression

This study was designed to examine relationships between roles of employed married women in Seoul, South Korea, perceptions of their work role, coping patterns, and levels of depression. The convenience sample contained 382 women, aged 25–55 years, who were living with their husbands and working at least 20 hr weekly. Participants completed five questionnaires: demographic, Center for Epidemiological Studies—Depression Scale, Index of Sex-Role Orientation, Role Sharing, and Coping Strategies. Multiple regression analysis revealed several statistically significant relationships. Higher levels of depression were found in women who perceived motherhood and career roles as incompatible, those who coped by working harder, and those who spent less time helping children with homework. Women who owned their houses had lower levels of depression.     

Rewards of technology: Explaining China’s reverse migration

China rewards Mainlanders with technology who return to China. Among entrepreneurs and scientists, technology is generating today’s reverse migration as the rewards for bringing back technology are significant. Many returnees do not bring the latest international technology; technology that is new for China suffices to create a comparative advantage in the domestic market, making the transfer of technology a key strategy for becoming a successful reverse migrant. This article shows statistically that those who said that they had returned because they possessed a new technology (55% of our sample) were less likely to have a new international technology than a technology that was new only for China. La Chine récompense les Chinois continentaux qui retoument au pays avec des moyens techniques. Les récompenses pour avoir rapporté des éléments technologiques étant significatives, c’est la technologie qui favorise la migration de retour actuelle chez les entrepreneurs et les scientifiques. Nombreux sont les rapatriés qui ne rapportent pas le dernier cri international en technologie; il suffit de revenir avec des moyens techniques qui sont inconnus en Chine pour créer un avantage comparé dans le marché intérieur. Ainsi, le transfert de technologies constitue une strategie privilégiée dans la réussite des rapatriés. Nos statistiques indiquent que chez ceux qui étaient retournés au pays parce qu¡ls y introduisaient une nouvelle technologie (soit 55% de notre échantillon), il était moins probable pour eux d’avoir de nouveaux moyens techniques intemationaux que de moyens techniques qui représentaient une nouveauté en Chine seulement.     

Comparing Self-differentiation and Psychological Well-being between Korean and European American Students

This study examined cross-cultural differences in the relationship of self-differentiation with self-esteem and depressed mood, two indices of psychological well-being. Participants were 427 Korean and 375 European American college students. The main findings were that the levels of all components of self-differentiation were greater for European Americans than for Koreans; self-differentiation was associated with psychological well-being more strongly in American samples than in Korean counterparts; and “I position” was the most powerful predictor on self-esteem in both groups. Results suggest that differentiation is a meaningful construct for understanding psychological adjustment of college students in collectivistic Korean society.This research was supported by the Chonbuk National University funds for overseas research, 2004.     

The Relationship of Culture and Empathy in Cross‐Cultural Counseling

Empathy has been identified as a core condition for providing counseling. There are numerous articles discussing the components of empathy. However, as the U.S. becomes increasingly ethnically diverse and the world becomes more globalized, there is little discussion on how empathy will be effective with diverse populations. This article discusses the interaction of culture and empathy and suggests guidelines for establishing cultural empathy.     

Alternative Multiple Imputation Inference for Categorical Structural Equation Modeling

The use of item responses from questionnaire data is ubiquitous in social science research. One side effect of using such data is that researchers must often account for item level missingness. Multiple imputation is one of the most widely used missing data handling techniques. The traditional multiple imputation approach in structural equation modeling has a number of limitations. Motivated by Lee and Cai’s approach, we propose an alternative method for conducting statistical inference from multiple imputation in categorical structural equation modeling. We examine the performance of our proposed method via a simulation study and illustrate it with one empirical data set.     

Waimānalo Pono Research Hui: A Community–Academic Partnership to Promote Native Hawaiian Wellness through Culturally Grounded and Community‐Driven Research and Programming

Although Hawai‘i is often portrayed as an idyllic paradise and is recognized as one of the healthiest States in the United States, pervasive health disparities exist among Native Hawaiians. Similar to other indigenous populations across the globe, these disparities are linked to unjust social and economic policies rooted in colonization and historical trauma. Western‐centric efforts to address these disparities have yielded limited results. Consequently, indigenous frameworks to decolonize western‐centric research processes have emerged. The Waimānalo Pono Research Hui is an example of a community–academic partnership that uses indigenous methodologies and principles of community‐based participatory research as the foundation to engage Native Hawaiian community members in research. Monthly gatherings are held where community members and academic researchers share a meal and discuss community priorities with the goal of shaping research and programming that are rooted in Native Hawaiian values. A mission for the group has been created as well as protocols for community engagement to ensure all projects that work with the Waimānalo Pono Research Hui are ethically sound and grounded in the community's preferences, cultural knowledge, and lived experiences. Our community members continually report that the Waimānalo Pono Research Hui has positively transformed their perception of and willingness to engage in research. Similarly, university students and academic researchers express how much their knowledge about working with communities has grown and inspired them. Creating spaces for communities and researchers to build authentic relationships and engage in ongoing conversations can promote culturally grounded and community‐driven research and programming.     

Pre-attentive mental processing of music expectation: event-related potentials of a partially violating and resolving paradigm

Auditory event-related potentials (ERPs) were investigated in an oddball paradigm to verify electrophysiological evidence of music expectation, which is a key component of artistic presentation. The non-target condition consisted of four-chord harmonic chord sequences, while the target condition was manifested by a partially violating third chord and a resolving fourth chord. The results showed that the specific mismatch negativity (MMN) elicited in the resolving chord is as robust as that elicited in the partially violating chord. Moreover, the P3b (P300) elicited in the resolving chord was smaller than the one in the violating chord. Taken together these data indicates that the human brain pre-attentatively may be able to anticipate a subsequent resolving chord when music expectation is generated by a partially violating chord.
