Comparability problems in the analysis of multiway data

Almost all methods for the analysis of multiway data assume that the comparison of any two entries in the data array under study reflects or represents meaningful content-specific information. This is especially the case if one wants the data analysis to yield insight into the real mechanisms underlying the data. Violation of this assumption may imply data-analytic results that are of doubtful quality at best and worthless in the worst-case scenario. In the present paper, we first clarify why comparability is a key assumption in most methods for multiway data analysis. Next, we list a number of reasons why this assumption is very often violated in practice. We then review a few possible approaches that have been advanced to deal with problems of comparability, and discuss their advantages and shortcomings. We conclude by clarifying that any satisfactory solution to comparability problems requires a very careful reflection about the data collection and the ultimate goal of the data analysis.     

SISO extended predictive control: implementation and robust stability analysis

The proposed algorithm of extended predictive control (EPC) represents an exact method for removing the ill-conditioning in the system matrix by developing a unique weighting structure for any control horizon. The main feature of the EPC algorithm is that it uses the condition number of the system matrix to evaluate a single tuning parameter that provides a specified closed-loop response. Robust analysis demonstrated that EPC is more robust in comparison with move-suppressed and m-shifted predictive controllers in all aspects of process variation in gain, delay, and time-constant ratios. Tuning of EPC is effective and simple since there is a direct relationship between closed-loop performance and its tuning parameter.     

New Labour,Street Homelessness and Social Exclusion: A Defaulted Promissory Note?

This article offers a critical appraisal of the ‘New Labour' governments’ (1997–2010) much vaunted commitment to confronting and combating the spectre of visible rough sleeping and its associated street culture. It reviews the trajectory of policy initiatives and welfare practices concerned with engendering the social inclusion of homeless people. It subsequently interrogates attempts to shape the behaviour of people experiencing homelessness through the imposition of greater conditionality and invocation of an ethic of self-responsibility. It stresses the importance of considering the role of actively engaged local communities in governing homeless people and regulating homeless service providers. It does this using an ethnographic case study of homelessness and housing need in a small market town in the south-west of England.     

中国古代建筑装饰的制约性研究

建筑装饰艺术是依附于建筑存在的，必然要受到建筑形制的制约，然而又促使中国古代劳动人民发挥了创造力的极致，使中国建筑装饰体系更加完整，从而走到了建筑装饰的制高点。本文试图分析中国古代建筑装饰的特点，研究其在发展过程中的制约性特征。并对如何继承传统，发扬民族特征提出疑问。

The role of housing policy in perpetuating conditional forms of homelessness support in the era of housing first: Evidence from Australia

Abstract

Despite widespread enthusiasm for Housing First approaches to addressing homelessness, conditional models of support that require ‘housing readiness’ persist in many jurisdictions. Existing research cites an ongoing commitment to conditionality amongst homelessness services providers as a key reason for its persistence. In this paper, we argue that State housing policies also play an important role in perpetuating conditionality in the homelessness sector. Drawing on research carried out in an Australian jurisdiction, we show how policies regarding the supply and allocation of social housing compel homelessness service providers—including Housing First services—to employ conditionality practices. We also demonstrate the detrimental impact this has on the housing outcomes of homelessness people with complex needs. We conclude that our findings challenge the claim made by some that Housing First constitutes a ‘paradigm shift’, and instead highlight the complex processes of policy translation and assemblage that shape the adaptation of Housing First in different contexts.
