Application of participatory principles to investigation of the natural world: An example from Chile

Participatory research in environmental and natural resources-related fields is premised on many of the same notions that underlie participatory processes in decision making. This study examines one instance of participatory research to assess the extent to which the documented benefits of participatory decision-making hold up in the context of research. A survey of Chilean shell-fishers engaged in research with marine biologists assesses the relationships between four variables: fishers’ participation in research, fishers’ opinions of biologists, fishers’ trust in biologists, and fishers’ acquisition of knowledge from biologists. Results illuminate the multidimensionality of these variables and suggest that complex interrelationships between them make the benefits of participatory research more nuanced than those reported for participatory decision-making. For instance, participatory research may provide low benefits when participatory research outcomes differ little from those produced solely by scientists. In addition, high-cost scenarios may result when outcomes of participatory research are inferior to those produced solely by scientists. A third downside may result when participation leads participants to increase their deference to scientific knowledge, thereby defeating the corroborative purpose of their participation. A fourth effect may occur when increased trust by in scientists results from participation, decreasing participants’ perceived need to take part in research.     

山东省胶南市七宝山铅矿区地质矿产特征综合研究

胶南七宝山位于胶东半岛东部地区,区域上属于胶南-威海造山带.山东省地质调查院在此开展普查工作,并通过激电测深、土壤测量、钻孔取芯,以及化学和光谱等分析方法,得出铅矿矿体赋存于断裂构造中,属岩浆热液充填型.矿体主要呈脉状、凸镜状,宽1～3 m,长70～200 m,主要矿体走向近南北,多倾向东.矿石有用化学成分主要为Pb、Ag、CaF2、Cu,Pb含量一般为1.36%～3.96%(平均3.11%),矿体平均厚度3.13m.

Performing a new regional geography

In this introduction to the Special Issue ‘Practising a New Regional Geography in Northland’, we call for a new regional geography. We use the experience of a field course to reflect upon the opportunities and challenges associated with doing ‘regional geography’ in the regions, a subdiscipline that has in recent decades been pushed into the backwaters of the discipline. We reinterpret the maxim ‘geography is what geographers do’ in a new way that emphasises pedagogy and research practice. The case of Northland and helping our students to learn experientially about community and environment under the rubric of sustainability allows us to argue the case for a reinterpretation of regional geography in these terms. We position the contributions in this Special Issue in terms of our call.

Should Women Count? A Context for the Debate*

Much recent feminist geographical scholarship emphasizes the utility of qualitative research methods; yet, a significant proportion of feminist research in geography is quantitative. Geographers' engagement with the ideas of feminist theorists has shed new light on the relationship between epistemology, methodology, and objectivity, which in turn has facilitated a reexamination of feminist uses of quantification. In providing a context for the debate over quantitative and qualitative methods, we argue that each has a place in feminist geographical research.     

同位素地球化学方法与地震研究及地震预报

通过在地震活动区对有关地质体的K—Ar、Ar—Ar、FT、TL、~(14)C、ESR、U系等同位素年代学、地下水及其释放气体的D/H、~(13)C/~(12)C、~(18)O/~(16)O等稳定同位素以及He、Ar等稀有气体同位素的研究,可获得有关新构造运动的时间序列、断层运动的时间、地质体热历史以及地下断层流体运动的许多重要信息。因而,同位素地球化学已逐渐在研究地震成因机制以及监测预报地震中发挥重要作用。
