The discursive construction of Japanese identity and its haunting others

This dissertation examined the formation of Japanese identity politics after World War II. Since World War II, Japan has had to deal with a contradictory image of its national self. On the one hand, as a nation responsible for colonizing fellow Asian countries in the 1930s and 1940s, Japan has struggled with an image/identity as a regional aggressor. On the other hand, having faced the harsh realities of defeat after the war, Japan has seen itself depicted as a victim. By employing the technique of discourse analysis as a way to study identity formation through official foreign policy documents and news media narratives, this study reconceptualized Japanese foreign policy as a set of discursive practices that attempt to produce renewed images of Japan's national self. The dissertation employed case studies to analyze two key sites of Japanese postwar identity formation: (1) the case of Okinawa, an island/territory integral to postwar relations between Japan and the United States and marked by a series of US military rapes of native Okinawan girls; and (2) the case of comfort women in Japan and East Asia, which has led to Japan being blamed for its wartime sexual enslavement of Asian women. These case studies found that it was through coping with the haunting ghost of its wartime past that Japan sought to produce "postwar Japan" as an identity distinct from "wartime imperial Japan" or from "defeated, emasculated Japan" and, thus, hoped to emerge as a "reborn" moral and pacifist nation. The research showed that Japan struggled to invent a new self in a way that mobilized gendered dichotomies and, furthermore, created "others" who were not just spatially located (the United States, Asian neighboring nations) but also temporally marked ("old Japan"). The dissertation concluded that Japanese foreign policy is an ongoing struggle to define the Japanese national self vis-à-vis both spatial and historical "others," and that, consequently, postwar Japan has always been haunted by its past self, no matter how much Japan's foreign policy discourses were trying to make this past self into a distant or forgotten other.

Sulfate and methane concentrations measured in pore water of sediment core GeoB13809-1 and GeoB13849-1

Several previous studies have shown that submarine mass-movements can profoundly impact the shape of pore water profiles. Therefore, pore water geochemistry and diffusion models were proposed as tools for identifying and dating recent (max. several thousands of years old) mass-transport deposits (MTDs). In particular, sulfate profiles evidentially indicate transient pore water conditions generated by submarine landslides. After mass-movements that result in the deposition of sediment packages with distinct pore water signatures, the sulfate profiles can be kink-shaped and evolve into the concave and linear shape with time due to molecular diffusion. Here we present data from the RV METEOR cruise M78/3 along the continental margin off Uruguay and Argentina. Sulfate profiles of 15 gravity cores are compared with the respective acoustic facies recorded by a sediment echosounder system. Our results show that in this very dynamic depositional setting, non-steady state profiles occur often, but are not exclusively associated with mass-movements. Three sites that show acoustic indications for recent MTDs are presented in detail. Where recent MTDs are identified, a geochemical transport/reaction model is used to estimate the time that has elapsed since the perturbation of the pore water system and, thus, the timing of the MTD emplacement. We conclude that geochemical analyses are a powerful complementary tool in the identification of recent MTDs and provide a simple and accurate way of dating such deposits.

(Table 1) Bulk geochemistry of sediment cores KH-79-3_L3 and KH-79-3_C3

The organic and isotopic geochemical study of two sediment cores (KH-79-3, L-3, and KH-79-3, C-3) from the Oki Ridge in the Japan Sea has revealed that total organic carbon (TOC) mass accumulation rates are extremely high in the 12-11 ka (calendar age) interval and TOC in the sections in the 24-17 ka interval is depleted in 13C by 3.5? relative to Holocene sediments. Alkenone sea surface temperature (SST) shows a decrease from 18° to 14°C from 17.5 to 11.6 ka and a sharp increase from 14° to 19°C from 11.6 to 11.1 ka. The SST changes are associated with the inflow of cold seawater with the vertical water mixing and the inflowof warm Tsushima Current into the Japan Sea. The d13C values for both 24-methylcholesta-5,22-dien-3?-ol (diatom marker) and dinosterol (dinoflagellate marker), are at their minimum from 24 to 17 ka, while those for long-chain alkenones are not. The theoretical considerations on d13C for biomarkers suggest low photosynthetic carbon demand of diatoms and dinoflagellates from 24 to 17 ka.

Global distributions of diazotrophs nitrogen fixation rates - Depth integrated values computed from a collection of source datasets - Contribution to the MAREDAT World Ocean Atlas of Plankton Functional Types

The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedented global data set for ecological and biochemical analysis and modeling as well as a clear mandate for compiling additional existing data and for focusing future data gathering efforts on key groups in key areas of the ocean. The present data set presents depth integrated values of diazotrophs nitrogen fixation rates, computed from a collection of source data sets.

Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review

Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the development of information technology, the use of technology in social work practice has risen dramatically. The aim of this literature review is to map out the state of the art of knowledge about the usage of ICT in elderly care and to figure out research-based knowledge about the usability of ICT for the prevention of loneliness and social isolation of elderly people. The data for the current research comes from the core collection of the Web of Science and the data searching was performed using Boolean? The searching resulted in 216 published English articles. After going through the topics and abstracts, 34 articles were selected for the data analysis that is based on a multi approach framework. The analysis of the research approach is categorized according to some aspects of using ICT by older adults from the adoption of ICT to the impact of usage, and the social services for them. This literature review focused on the function of communication by excluding the applications that mainly relate to physical nursing. The results show that the so-called ‘digital divide’ still exists, but the older adults have the willingness to learn and utilise ICT in daily life, especially for communication. The data shows that the usage of ICT can prevent the loneliness and social isolation of older adults, and they are eager for technical support in using ICT. The results of data analysis on theoretical frames and concepts show that this research field applies different theoretical frames from various scientific fields, while a social work approach is lacking. However, a synergic frame of applied theories will be suggested from the perspective of social work.

Diagnóstico del rendimiento académico de estudiantes de una escuela de educación superior en México

El objetivo del artículo es realizar un diagnóstico sobre la percepción de los factores que intervienen en el rendimiento académico de los estudiantes de cinco carreras universitarias en una escuela de educación superior en México, para así reconocer las áreas de oportunidad que permitan sugerir políticas y estrategias para elevar su rendimiento. Se utilizó una muestra de 1651 estudiantes, se obtuvieron los datos a partir de un cuestionario con treinta preguntas que estudian la percepción del rendimiento académico en escala tipo Likert. Se realizó un análisis factorial exploratorio que permitiera reducir los datos, facilitar la interpretación y validar el instrumento. Se identificaron tres factores: a) el rol de los profesores, b) la evaluación y c) la motivación de los estudiantes. Se llevó a cabo un análisis comparativo por carrera. Se encontró que los estudiantes perciben que la mayoría de los maestros no se preocupan por la condición de los jóvenes en situación de reprobación. Además, casi no motivan y carecen de expresiones de sentimientos de orgullo por los logros académicos de los estudiantes. La mitad de los participantes piensa que los docentes no cubren el temario en su totalidad. Se detectó que los estudiantes poseen una alta motivación siendo esto positivo porque son alumnos dedicados y responsables. Se concluye realizando una serie de sugerencias y explicando las implicaciones que tiene este trabajo para las instituciones de educación superior.

Giving Peru a productivity boost : towards a system of continuous education and training

In spite of impressive rates of economic growth, the quality of the labor force’s human capital is considered a major challenge for sustaining medium term economic growth in Peru. This note reviews the skills of the Peruvian labor force, and the status of the continuous education and training system. Based on such an assessment and on learnings from international best practices, it proposes a system of continuous education and training that draws from international best practices, but that addresses local capacity and institutional issues.

El efecto de One Laptop per Child en las prácticas de enseñanza y en la distribución del tiempo en el hogar.

El objetivo del documento es identificar dos posibles canales que expliquen por qué el programa OLPC en el Perú no generó efectos significativos en el rendimiento de los niños. Para ello se estimará el efecto de la introducción de tecnología (en este caso, laptops) sobre dos potenciales canales: el método de enseñanza del profesor y el tiempo destinado a actividades dentro del hogar. En primer lugar se espera que la entrega de laptops haya reducido la probabilidad que el alumno reciba un método centrado en el alumno donde se promueven las actividades cooperativas. A pesar de que este tipo de método genera un impacto positivo en el rendimiento del alumno. En segundo lugar, se espera que la entrega de laptops haya reducido el tiempo destinado a quehaceres domésticos, cuando estos inciden negativamente el rendimiento de los alumnos. A través de una estimación de mínimos cuadrados ordinarios en dos etapas y bajo una regresión simple se encuentra que la entrega exógena de laptops reduce la probabilidad del profesor de implementar un método centrado en el alumno con actividades cooperativas entre 10 y 8 puntos porcentuales para los cursos de lenguaje y matemáticas respectivamente. Para lenguaje; ello incide en el rendimiento, ya que este método genera un efecto positivo y significativo en el rendimiento de 0.025 desviaciones estándar. Mientras que, para matemáticas, el método no tiene efecto alguno en el rendimiento académico.

Fear of labor rigidities: the role of expectations on employment growth in Peru

Se han realizado muchos estudios que analizan el efecto de la estricta legislación de protección del empleo. Sin embargo, casi todos ellos se han enfocado en un impacto a posteriori; dejando de lado un segundo canal, pero igualmente importante: las expectativas. Este trabajo tiene como objetivo analizar el papel de las expectativas en el mercado laboral formal e informal peruano.
