Abstract Sorption of the phenolic compound 2,4-dichlorophenol (2,4-DCP) by pyrolyzed and different forms of treated residue of Jordanian oil shale was examined. Pyrolyzed oil shale was prepared using a fluidized bed reactor at 520ºC in the presence of nitrogen. Physical activation was carried out by treating the resultant pyrolyzed oil shale with CO2 at 830ºC, while chemical activation of oil shale was carried out using KOH and ZnCl2 as impregnating agents. Uptake of 2,4-DCP onto the different types of sorbents increased in the order ZnCl2-OS > Pyr-OS > CO2-OS, with minimal uptake when KOH-OS was used. The process was found to be exothermic in nature. An increase in the initial pH of the solution negatively influenced the sorption of 2,4-DCP. The isotherm experimental data fitted reasonably to the Langmuir, Freundlich and Redlich-Paterson models. According to kinetics studies, the rate of 2,4-DCP sorption onto ZnCl2-OS was faster than that by Pyr-OS. Three kinetics models, namely the Morris-Weber model, Lagergren model, and pseudo-second-order model (PSOM), were applied to represent the experimental results for both pyrolyzed and ZnCl2-oil shale sorbents.

The article presents quantitative characteristics of the prevalence and volumes of hidden household incomes. An econometric estimate of the prevalence of hidden incomes was carried out on the panel data of the “Russian Monitoring of the Economic Situation and Health of the Population of the Higher School of Economics” (periods from 2000 to 2017), the size of the hidden income component was obtained on the basis of the Pissarides-Weber model. Estimates of the share of hidden income households and an estimate of the share of hidden incomes revealed two different trends: their predominant distribution among residents of villages and urban-type settlements and the larger size of these incomes among households of regional centers.

Weber Model

PurposeSmart governance ultimately relates to the ability of political administrations to elicit trust and public confidence. Political administrations normally generate rational policies that arise from their context-sensitive goals. The capability of an administration to develop and implement policies is measured as efficacy, which can influence the value and stability of an administration. However, policy development and implementation is not only an attribute of a political administration but also of its bureaucracy. The purpose of this paper is to explore the nature of bureaucracies, representing them as complex and dynamic.Design/methodology/approachA traditional blueprint model of a bureaucracy comes from Weber, seen to be a servicing body for the implementation of political policy decisions resulting from a process of governance. An alternative model arises from the fictional works of Kafka, which is underpinned by a firm conceptual basis of a bureaucracy that confronts that of Weber. Agency theory will be used to model bureaucracies, and comparisons will be made between the Weber and Kafka conceptualisation.FindingsThere are broad models of a bureaucracy that arise from different propositions such as a Weber and a Kafka model, the latter being more representative of administrations. Any attempts to measure comparative efficacy across political systems or administrations may well lead to failure due to the distinctions in the nature of the bureaucracies that they maintain. The paper argues that the Weber model is an unattainable boundary representation of a bureaucracy. In contrast, Kafka’s more pragmatic conceptualisation can be modelled as a pathological autonomous system that is both complex and adaptive. Such pathologies can be harmful to the implementation of socially improving policies.Practical implicationsThe paper shows that even where a political administration has policy initiatives that can improve society, these can be corrupted and misdirected by its bureaucracy, mistakenly believed (by the administration) to be dedicated to the service of the administration, rather than the bureaucracy’s own self-interests.Originality/valueNo other approach has been able to graphically represent the relative natures of different bureaucracies, or their pathologies.
