Confronting Confucian Understandings of the Christian Doctrine of Salvation : A systematic theological analysis of the basic problems in the Confucian-Christian dialogue

The aim of the present study is to analyze Confucian understandings of the Christian doctrine of salvation in order to find the basic problems in the Confucian-Christian dialogue. I will approach the task via a systematic theological analysis of four issues in order to limit the thesis to an appropriate size. They are analyzed in three chapters as follows: 1. The Confucian concept concerning the existence of God. Here I discuss mainly the issue of assimilation of the Christian concept of God to the concepts of Sovereign on High (Shangdi) and Heaven (Tian) in Confucianism. 2. The Confucian understanding of the object of salvation and its status in Christianity. 3. The Confucian understanding of the means of salvation in Christianity. Before beginning this analysis it is necessary to clarify the vast variety of controversies, arguments, ideas, opinions and comments expressed in the name of Confucianism; thus, clear distinctions among different schools of Confucianism are given in chapter 2. In the last chapter I will discuss the results of my research in this study by pointing out the basic problems that will appear in the analysis. The results of the present study provide conclusions in three related areas: the tacit differences in the ways of thinking between Confucians and Christians, the basic problems of the Confucian-Christian dialogue, and the affirmative elements in the dialogue. In addition to a summary, a bibliography and an index, there are also eight appendices, where I have introduced important background information for readers to understand the present study.

A systematic-ecological approach to Baltic Sea ice studies of algae and protists

The seasonal occurrence of sea ice that annually covers almost half the Baltic Sea area provides a unique habitat for halo- and cold temperature-tolerant extremophiles. Baltic Sea ice biology has more than 100 years of tradition that began with the floristic observation of species by the early pioneers using light microscopic techniques that were the only thing available at the time. Since the discovery of life within sea ice, more technologies have become available for taxonomy. Electron microscopy and genetic evidence have been used to identify sea ice biota revealing increased numbers of taxa. Meanwhile ecologists have used light microscopic cell enumeration in addition to the chemical and physical properties of sea ice in attempts to explain the food web structure of sea ice and its functions. Thus, during the Baltic winter, the sea ice hosts more abundant and diverse microbial communities than the water column beneath it. These communities are typically dominated by autotrophic diatoms together with a diverse assortment of dinoflagellates, auto- and heterotrophic flagellates, ciliates, metazoan rotifers and bacteria, which are mostly responsible for the recycling of nutrients. This thesis comprises ecological and systematic studies. In addition to the results of the previous studies carried out on landfast ice, the data presented here provide new insight into the spatial distribution of pelagial sea ice, which has remained largely unexplored. The studies reveal spatial heterogeneity in the pelagial sea ice of the Gulf of Bothnia. There were mismatches in chlorophyll-a concentrations and in photosynthetic efficiencies of the communities studied. The temporal succession was followed and experimental studies performed investigating the community responses towards increased or decreased light in landfast ice in the Gulf of Finland. The systematic studies carried out with established dinoflagellate cultures revealed a new resting cyst belonging to common sea ice dinoflagellate, Scrippsiella hangoei (Schiller) Larsen 1995. The cyst can be used to explain the overwintering of this species during prolonged periods of darkness. The dissimilarities and similarities in the material isolated from the sea ice called for description of a new subspecies Heterocapsa arctica ssp. frigida. The cells obtained in the cultured material were unlike those of the previously described species, necessitating description of ssp. frigida. As a result of its own unique habitus, the subspecies had been noted by Finnish taxonomists during the past three decades and thus its annual occurrence and geographical distribution in the Baltic Sea. This illustrates how combining ecology and systematics increases our understanding of organisms.

The family Herbertaceae and its novel systematic position within liverworts

Taxonomic relationships of the liverwort genus Herbertus in Asia were examined. In addition, the phylogeny of the family Herbertaceae and its close relatives was investigated and analyses conducted of higher level relationships within the entire liverwort phylum. Species of Herbertus show great plasticity in various morphological characters, resulted in a large number of described species. This study was the first comprehensive revision of Asian Herbertus, with 12 species recognized for the continent. Eleven names were reduced to synonymy under earlier described species, and one species was excluded from the genus. Herbertus buchii Juslén was described as a new species. Phylogenetic analyses based on both molecular and morphological characters resolved the families Vetaformaceae, Lepicoleaceae, and Herbertaceae (including Mastigophoraceae) as a monophyletic entity. This clade is among the most derived groups within the leafy liverworts and comprises mostly isophyllous plants, all of which have bracteolar antheridia. The relationships of Mastigophoraceae have formerly been controversial. My results confirm the view that this family is closely related to Herbertaceae, Lepicoleaceae, and Vetaformaceae. In the proposed new classification Mastigophoraceae is included in Herbertaceae. Phylogenetic relationships within the liverworts were reconstructed using both chloroplast and nuclear sequences as well as morphological characters. These analyses were the most comprehensive to date at the time of publication. Previously it was believed that liverworts had a common ancestor with an erect, radial gametophyte and a tetrahedral apical cell. The leafy liverworts were arranged based on the assumption that similar structures had repeatedly developed in many different suborders, with evolution proceeding from erect and isophyllous to creeping and anisophyllous plants. The complex thalloid liverworts were assumed to be the most derived group. By contrast, our studies resolved a clade comprising Treubia and Haplomitrium as the earliest extant liverwort lineage. According to our results the complex thalloids are also an early diverging lineage, and the simple thalloids, traditionally classified together, are a paraphyletic group. Within leafy liverworts, the hypothesis of repeated evolution from isophyllous to anisophyllous plants based on the assumption of a basal unresolved polytomy was rejected. Fundamentally, the leafy liverworts can be divided into three groups. In conflict with the earlier hypotheses, the isophyllous liverworts, including Herbertaceae, were resolved as derived lineages within the liverworts.
