Abstract In this paper, changes of the non-forest xerothermic vegetation of the “Murawy Dobromierskie” steppe reserve which occurred in the period 1993-2012 are examined. The material comprises 50 relevés, of which 43 date from 2012 and the other 7 - from 1993. Reléves were arranged in 5 analytic tables. A synoptic table was also compiled, and for each syntaxonomical species group distinguished, values of the cover coefficient (C), the collective group share index (G), and the systematic group value (D) were estimated and compared. On the basis of the obtained results, a significant decline in abundancy and/or constancy was observed within the following groups: Ch. Artemisietea vulgaris, Ch. Cirsio-Brachypodion pinnati, Ch. Festuco-Brometea, Ch. Geranion sanguinei, Ch. Koelerio-Corynephoretea, and Ch. Origanetalia and Trifolio-Geranietea sanguinei, whereas for the taxa of the Rhamno-Prunetea, a notable increase in the share of the reserve vegetation was recorded. A sizeable expansion of the moss layer was also observed in this period. The results are discussed with special regard to differences in the methodical background of both field studies.

Conspecific rape often increases male reproductive success. However, the haste and aggression of forced copulations suggests that males may sometimes rape heterospecific females, thus making rape a likely, but undocumented, source of hybrids between broadly sympatric species. We present evidence that heterospecific rape may be the source of hybrids between Black-footed and Laysan Albatrosses (Phoebastria nigripes, and P. immutabilis, respectively). Extensive field studies have shown that paired (but not unpaired) males of both of these albatross species use rape as a supplemental reproductive strategy. Between species differences in size, timing of laying, and aggressiveness suggest that Black-footed Albatrosses should be more successful than Laysan Albatrosses in heteropspecific rape attempts, and male Black-footed Albatrosses have been observed attempting to force copulations on female Laysan Albatrosses. Nuclear markers showed that the six hybrids we studied were F1s and mitochondrial markers showed that male Black-footed Albatrosses sired all six hybrids. The siring asymmetry found in our hybrids may have long persisted because an IM analysis suggests that long-term gene exchange between these species has been from Black-footed Albatrosses into Laysan Albatrosses. If hybrids are sired in heterospecific rapes, they presumably would be raised and sexually imprinted on Laysan Albatrosses, and two unmated hybrids in a previous study courted only Laysan Albatrosses.

The research discuss about forced labor practices in Indonesia under Japanese Military invation. The focus of this paper is to highlight how the idea of forced labor context, the mobilization process and to describing, also reveals preliminary findings on the ground in relation to Romusha's case study at village in Boyolali. In this papaer also will be presented how the future of that issues and humanitarian movement Romusha in Indonesia recently. I used literature and field studies by presenting some of the survivor (ex-romusha). The result of this study bring the conclusions of discussion and history alignment to the younger generation should be continue  and so that we can moving into a better future.Keywords: romusha in indonesia; japanese military invation

The Experience Sampling and Reconstruction Method (ESRM) is a research method suitable for user studies conducted in situ that is needed for the design and evaluation of ambient intelligence technologies. ESRM is a diary method supported by a distributed application, Reconexp, which runs on a mobile device and a website, enabling surveying user attitudes, experiences, and requirements in field studies. ESRM combines aspects of the Experience Sampling Method and the Day Reconstruction Method aiming to reduce data loss, improve data quality, and reduce burden put upon participants. The authors present a case study of using this method in the context of a study of communication needs of working parents with young children. Requirements for future developments of the tool and the method are discussed.

This chapter presents issues that may arise in human-centered research in health care environments. The authors first discuss why human-centered approach is increasingly employed to study and to design health care technology. They then present some practical concerns that may arise when conducting qualitative research in medical settings, from research design, to data collection and data analysis, and to technology design. Many of these concerns were also experienced in their own human-centered field studies conducted in the last few years. The authors conclude the chapter by illustrating some of these issues using their own research case study that investigated nurses’ information flow in a hospital ward.

This article focuses on the characteristics, causes, and patterns of the anti-demolition actions by churches in Wenzhou. Based on my six field studies from July 2014 to February 2016, I discovered that: (1) these actions are more explicit in Wenzhou churches due to their regional distinctiveness; (2) a wide range of differences can be observed among Wenzhou churches due to their doctrinal diversity; and (3) ‘poor pastors’ have taken the leadership roles in the anti-demolition activities instead of the ‘boss Christians’. Considering the ongoing tension in the Chinese religious environment between central government planning and free market operation, the author points out that the pastoral district system in Wenzhou plays a very important role in anti-demolition and offers the ‘cost–benefit’ exchange theory to explain the pattern of the anti-demolition activities by Wenzhou churches.

The present study evaluated and selected the best location among susceptible landfill sites in Rudbar County using 27 criteria, as the maximum effective criteria, in the decision-making process. The emergence and comparison between the two methods of fuzzy and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) with an engineering–geological approach have been conducted to obtain the best results. In this regard, inappropriate regions for landfill construction have been restricted after the conflation of two maps based on the restriction criteria. Then, the direction of prevailing winds and proper area for landfill construction was investigated for a 20-year perspective, and the regions that had more than 35-hectare area and were not located in the direction of the prevailing winds have been identified as responsive sites for landfill construction. Ultimately, selected susceptible regions were prioritized separately based on the TOPSIS and fuzzy methods. To ascertain the accuracy of the results and the reality of the resulted models, complementary field studies, geotechnical digging, and engineering–geological experiments have been used as verification parameters. According to the results of the verification, the fuzzy model having maximum matches with the verified data has been suggested for prioritizing susceptible regions.

In Malaysia, there is a notable increase in the number of bankruptcy cases. The personal bankruptcy trend has become one of the major concern to the government. The purpose of this research is to study the factors lead to personal bankruptcy. This research tested the few factors effect on personal bankruptcy based on Klang Valley residents. The research used a quantitative approach and data was gathered from survey questionnaire. The questionnaire measurement quantify the respondent’s response with the help of five point Likert scale. Respondents was designated to respond on the questionnaire by simple random sampling techniques. Data collected was analyzed using Pearson correlation coefficient and multiple regression analysis. The data has been presented in the form of tables. Relationship that were assessed; credit card debts, money management, financial literacy and non-performing loan effects towards personal bankruptcy. The finding shows that there are positive relationship between money management, financial literacy and non-performing loan.
