Sampling Approach

Abstract Background Understanding the burden of common mental health disorders, such as depressive disorder, is the first step in strengthening prevention and treatment in humanitarian emergencies. However, simple random sampling methods may lead to a high risk of coercion in settings characterized by a lack of distinction between researchers and aid organizations, mistrust, privacy concerns, and the overarching power differential between researchers and populations affected by crises. This case analysis describes a sampling approach developed for a survey study of depressive disorder in a Syrian refugee camp in Greece (n = 135). Discussion Syrian refugees face an extraordinarily high burden of depressive disorder during the asylum process (43%), necessitating population screening, prevention, and treatment. In order to preserve the informed consent process in this refugee camp setting, the research team developed a two-phase sampling strategy using a map depicting the geographical layout of the housing units within the camp. In the first phase, camp management announced a research study was being undertaken and individuals were invited to volunteer to participate. The participants’ container (housing) numbers were recorded on the map, but were not linked to the survey data. Then, in the second phase, the camp map was used for complementary sampling to reach a sample sufficient for statistical analysis. As a result of the two phases of the sampling exercise, all eligible adults from half the containers in each block were recruited, producing a systematic, age- and sex-representative sample. Conclusions Combining sampling procedures in humanitarian emergencies can reduce the risk of coerced consent and bias by allowing participants to approach researchers in the first phase, with a second phase of sampling conducted to recruit a systematic sample. This case analysis illuminates the feasibility of a two-phase sampling approach for drawing a quasi-random, representative sample in a refugee camp setting.

Transportation Type

Public transportation can be viewed as a key determinant and consequence of the social and spatial formation and development of contemporary cities and regions. Transportation policy generally combines four categories of instruments, i.e., investment, pricing, regulation and subsidy, to generate viable alternatives. Capital investment in public transportation supports the purchase of equipment and facilities including rolling stock, tracks, control equipment, and the construction of terminals, stations, parking lots, maintenance facilities and power generating facilities. Risk governance for public transportation investments looks at how risk-related decision-making unfolds when a range of actors is involved, requiring co-ordination and possibly reconciliation between a profusion of roles, perspectives, goals and activities. In this paper, a two-phased multicriteria methodology is proposed to select the best investment alternative for public transportation with respect to the predetermined criteria. In the first phase, a selection among transportation types is made, and in the second phase, a selection among transportation modes of the selected transportation type is made. A case study for Istanbul is given in the application section.

Purpose – This paper aims to investigate how dynamic capabilities enabled survival in a select group of brewers, during one of the lengthiest and most severe industry consolidations in history. In doing so, we advance Abell’s (1978) theory of strategic windows through integration with the resource-based view of the firm. Design/methodology/approach – Using a mixed method approach, we first apply case study methods to develop hypotheses around the timing and level of operational capability required for survival. In the second phase, we test these hypothesized estimations on the USA Brewing population. Findings – Indicate that brewers which had advanced distribution and manufacturing operational capabilities before the strategic window of opportunity closed had higher survival rates. Practical implications – This study reinforces the importance of making timely strategic investments in capabilities. Originality/value – The integration of strategic window and capability theories advances our understanding of the roles that capabilities and time play in determining firm survival.

Wineyard pruning utilization for energy purpose is not only a theoretical possibility, the machine background has also been developed. Economic- and environmental experimentations has made by specialists and they seek to developed the best practice in logistics suitable for local conditions and they propagate the results for the potential users. Nevertheless, the utilization does not seem to be typical in Hungary and some other wine-grower countries. For example, in Hungary the additional energy from vineyard pruning eventuates – tillage, nutrient supply; – phy+tosanitary, environmental pollution; – energy management and economic questions. In Hungary the most important problem is practice of the vineyard pruning utilization were mentioned by the users is the establishment of collection system and the high logistic costs as Marczinkó (2007) experiences confirm this. As I experienced in practice, the winegrowers are uninterested in utilization. Most of them burn it at the end of the vineyard in many cases without considering of the relevant statutory prohibition. As my own several years expriment shows at Mátra wine region it is not the technical background which causes the failure. We can use effectively balers or chippers for collection. The cost of chipping is 14 535–27 000 Ft per hectars with the introduced technologies on Mátra wine region. The cost of 1 GJ of heat production is 606–1125 Ft. We can substitute the fuel with vineyard pruning and it means approximately 115 000 Ft saving for a family household per year.

Simple Stochastic Model

This note presents an important improvement for optimal sampling schemes based on the anticipated variance. The anticipated variance is defined as the average of the design-based variance under a simple stochastic model in which the trees are assumed to be uniformly and independently distributed within a given number of so-called Poisson strata. We consider two-phase two-stage cluster sampling schemes in which costs and terrestrial second-phase sampling density can vary over domains. The estimation procedure is based on post-stratification with respect to so-called working strata that do not need to be identical with the Poisson strata, usually unknown, which induces a lack of fit. It is then possible to derive analytically the optimal sampling schemes. Data from the Swiss National Inventory illustrates the method.

Back lanes are ubiquitously found in every city as they are a required component according to the by-laws. The intention of back lane is to serve as a service road and consequently society tends to neglect and had led to a forgotten public space due to its lack of maintenance. Thus, this has discouraged the pedestrian movement as it is unsafe because the laneway is mainly hidden from public eye. Therefore, it became a space for undesirable activities to be taken place especially for hoodlums. In line with the Kuala Lumpur Tourism Master Plan 2015-2025, that gives emphasise to revitalise forgotten spaces, this research looks into the issues of back lanes in Petaling Street with the aims to unlock its potentials. The study adopted a qualitative approach through 2 phases. The first phase is through literature review to study and understand its historical background follows by site observation through photographs and recording of the site existing conditions. The second phase is through interviews with urban planning experts and business owners to discuss the historical value, issues and parameters to revitalize the back lane. The outcome of the research divulges that revitalization of back lane and shifting the front façade to the back lane or adapting to a double façade are able to greet the public with new urban social spaces and that tenants are able to utilize and give it a new meaning.

Collaboration between companies, especially for SMEs, can increase their ability to compete in new global markets. The emergence of new wine-producing countries over recent decades allows to evaluate its impact on the performance of a collaborative supply chain in countries with wine production tradition. This chapter describes the collaboration in the interface wine-grower/wine maker in a Portuguese wine region (Setúbal Peninsula). It reveal that intensification of collaboration between wine companies could increase their competitiveness in the domestic and the international markets, due the benefits it endorses. It also exposes some factors that stand out as conditioners to the operationalization of a deep collaboration, restricting it to just a few activities. The results of a case study performed suggested that the wine industry structure and the product characteristics are factors that negatively influence the intensity and the extension of collaboration. Trust is the intangible element that stands out as critical to the intensity of collaboration.
