Abstract

A frequency tunable half‐wave resonator at 3 GHz is presented with a microelectromechanical systems (MEMS) variable capacitor as the tuning element. The capacitor is fabricated using the multi‐user MEMS process (MUMPs) technology provided by JDS/Cronos, and transferred to an alumina substrate by an in‐house developed flip‐chip process. This capacitor is electrostatically actuated. The resulting CV response is linear with a slope of 0.05 pF/V for a wide range of actuation voltages. The MEMS device has a capacitance ratio of 3:1 for 0‐70 V bias, with a Q‐factor of 140 measured at 1 GHz. A half‐wave tunable microstrip resonator with bias lines is designed to include this MEMS device, which exhibits linear tuning over 180 MHz (6 percent) centered around 3 GHz with a constant 3 dB bandwidth of 160 MHz over the entire tuning range. The power consumption of the MEMS device was measured to be negligible.

Abstract

Task groups are semi‐autonomous working groups with specific responsibilities, delivering to specific aims and targets. If created effectively, they can form the basis of a flexible, organic, delayered organisation. However, bringing about the change from traditional hierarchical structures to task group structures is not straightforward. The changes are threatening to many of the established individuals and groups. Explains the key principles underlying a task group structure and highlights the issues to be addressed when making the change.

Abstract

Purpose

This purpose of this study is to explore the impact of global trend of economic integration and interconnectedness which has drawn the attention of world economies and their implications on trade inflow. This trajectory has its impact, either positive/negative, on key macroeconomic indicators, to say the least on environmental sustainability, especially emerging economies. To this end, the need to explore the connection between foreign direct investment (FDI) inflow and energy consumption amidst the wave of economic globalisation is timely and pertinent for the case of Turkey.

Design/methodology/approach

This study seeks to explore the interaction between the outlined variables in a carbon-income framework for annual time series data from 1970 to 2016. A series of econometrics strategies was used consisting of unit root tests to examine the stationarity properties of the highlighted series. Subsequently, Pesaran’s Bounds testing technique is used to explore the long-run equilibrium relationship between the highlighted variables in conjunction with the Johansen cointegration test. For long-run regression coefficients, Pesaran’s autoregressive distributed lag and dynamic ordinary least squares methodology are used, and innovative accounting approaches are used to explore the responsiveness of each variable on another.

Findings

Empirical results validate the pollution haven hypothesis (PHH) in the long run for the case of Turkey. Thus suggesting that FDI inflow induced environmental degradation in Turkey. Additionally, this study observed that renewable energy, on the contrary, improves the quality of the environment. This study also affirms the presence of the environmental Kuznets curve phenomenon, indicating that Turkey, at its early stage of economic trajectory, emphasis is on economic growth rather than environmental quality. This suggests a need for more deliberate action(s) by the government administrators to pursue cleaner FDI inflow and energy technologies and strategies to foster a clean environment in Turkey and a cleaner ecosystem at large.

Originality/value

This study is unique in its choice of variables which is in line with the United Nations Sustainable Development Goals (SDGs) agenda to be achieved by 2030 and is very limited in the extant literature. From the economic perspective, the effect of the PHH is of interest especially to ascertain the extent the interplay among the variables has on the economy of Turkey. The empirical insights on PHH hypothesis have received less documentation in the extant literature especially for emerging economy like Turkey. Thus, this study seeks to revisit this theme for Turkey with aim to presents environmentally sustainable strategies without compromise for economic growth. Thus, this study seeks to revisit this theme.

Abstract

Purpose

Discussions on environment-friendly production connected with the concerns of growing biomass emissions have gained much attention. In this regard, this study aims to explore the issue of biomass energy consumption and its related emission effects on the economic and environmental well-being of the economy of Cyprus.

Design/methodology/approach

This study sources time series data on specific variables from the Global Material Flow and the World Bank’s World Development Indicators (WDI, 2020) between 1990 and 2016. The Robust least square (ROB-L2) in conjunction with Pesaran autoregressive distributed lag (ARDL) methodology analysis techniques was used in addition to the Granger causality tests to examine the direction of causality flow between the variables under consideration.

Findings

The results indicate that biomass energy usage in the long run reduces pollution and negatively correlates with CO2 emissions level. Also, the decline of emission is influenced by increased foreign direct investment (FDI), thus, activities of foreign investors contribute to combating emission in the country. According to empirical results, non-renewable energy consumption showed both positive and negative influences on increased emission level, whereas economic growth is increasing carbon dioxide emission for the case of Cyprus.

Originality/value

This study applies current reliable data that offers renewed insights and sheds light on the state of affairs on biomass utilization from a developing country perspective. Additionally, it extends the discourse on the impact of biomass utilization on CO2 emissions by considering the impact of FDI, trade flow and energy consumption in a carbon-income function built on the liner version of the environmental Kuznets curve hypothesis. Although this is by no means exhaustive, the study pioneers the discourse on how FDI with biomass utilization among other relevant variables influences carbon dioxide emission.

Abstract

PC clones are well suited to anyone who has uses for IBM‐compatible software and is not over‐awed by those three magic letters. Clones now hold a much larger microcomputer market share than IBM. They frequently offer more power and better features, almost always at a much better price. But clones vary greatly in quality, reliability, and even compatibility. A potential purchaser of a clone should read reviews, and, if possible, run less well‐known clones through a series of tests prior to purchasing one. Crawford details a series of tests that were conducted by The Research Libraries Group, Inc., when it evaluated clones to serve as terminal replacements. These tests were designed to evaluate compatibility, quality of manufacturing, reliability of components, speed, and related characteristics. The results of those tests, when applied to several XT‐ and AT‐compatible clones, are presented.

Abstract

No one concerned for the dignity of letters can have failed to notice the increasing voracity and audibility of publishers' advertising of recent years. With this in mind I have been studying the literary section of an issue of the Observer. The results are disquieting. The “Books of the Day” feature runs from page 4 to page 9. On page 4 the text proper occupies three centre columns (not quite full columns, for Michael Joseph butts in with an advertisement across the foot). It is flanked on the left by Hodder and Stoughton, a two‐column spread from top to bottom; on the right is another two‐column spread of which Victor Gollancz has the lion's share. Hodder's display is a series of drab shaded panels, Gollancz's is a characteristically resonant proclamation in heavy type: the two in opposition strike discords in the midst of which the actual matter of the book reviews twitters faintly like a virginal trying to be heard in a mass‐meeting of trombones and bugles. Page 5 is split clean in half, three columns being devoted to text and the remainder—a massive four‐column spread—being again dedicated to Mr. Gollancz's commercial purposes. Page 6 repeats the tale—three columns of text to four of advertisements. On pages 7 and 8 the proportion of advertisement to text is equally heavy. On page 9 (the last of the literary section) the comparatively “decent pomp” of Harrap and Cassell is to the forefront—but by some oversight a dividend of two half‐columns of text above the average quota has been allowed to creep in. In all, the six book pages of one of our leading Sunday journals are carved up, roughly, as: text, nineteen columns; advertisements, twenty‐three columns.

Abstract

Vauxhall Motors Ltd. have carried out a major conversion to their plant for plating vehicle components against corrosion. The Tri‐Ni‐Nickel Seal process, recently developed by the Electro‐Chemical Engineering Co. Ltd., is now being used for bumpers and hub covers—parts nearest the road and thus most vulnerable—for all passenger cars and light vans. This treatment is claimed to increase corrosion resistance to compare with that given by stainless steel and aluminium, as these materials are used in motor cars.

Abstract

Purpose

Sustainable tourism is becoming more popular all over the world. Eco-friendly (green) hotels are properties that are friendly to the environment and are becoming increasingly popular among green travellers. Electronic word-of-mouth is a technique of communicating with consumers in order to share their experiences, and it is a significant marketing tool for hotels. This paper aims to identify the main themes shared in online reviews by tourists visiting eco-friendly hotels, and which of these themes were associated with satisfaction and dissatisfaction ratings.

Design/methodology/approach

The research used qualitative content analyses to analyse 1,202 user-generated content of the top 10 hotels in UK shared by guests on an online platform.

Findings

The analyses revealed nine themes in descriptions of airline travel experiences. These are “hotel amenities”, “services”, “location”, “staff”, “eco” (eco-friendly activities), “value” and “recommend/revisit” (intentions). Negative comments are associated with the “bathroom”, “mattress”, “water”, “bed”, “price”, “shower”, “Wi-Fi” and “restaurant” concepts.

Originality/value

This study differs from previous research in which it aims to address a void in the literature on the shortcomings of research focused on finding the dominant themes expressed in online reviews by tourists visiting eco-friendly hotels, and it does so using data mining approach.

Abstract

Purpose

The purpose of this paper is to test the relationship between the belief in redeemability – Version 2 (BIR-2) Scale and desistance from crime. It also seeks to explore how patterns of responding on the BIR-2 with offenders compare to previous patterns of responding in the general public.

Design/methodology/approach

The authors report the results of a study of offenders using the belief in redeemability – Version 2 (BiR-2) scale. In total, 180 offenders under the supervision of the Community Corrections Service (formerly the Probation and Parole Service) of New South Wales completed the ten-item questionnaire and when these data were combined with demographic and reoffending data collected by Corrective Services New South Wales, 168 sets of useable data were collected. Scores on the BIR-2 scale were compared to Level of Service Inventory – Revised (LSI-R) score, Most Serious Offence category, Aboriginal and Torres Strait Islander status, number of custodial sentences in previous five years, age, gender and reoffending.

Findings

Results showed that the sample overall was closely representative of the caseload from which the study sample was drawn (a metropolitan community corrections office) and that BIR-2 scores showed a small, significant, negative correlation with LSI-R scores. Analysis of re-offending data indicated a small, positive, but non-significant correlation with BIR-2. Implications of this are discussed and future research outlined.

Practical implications

The paper suggests that it is worth attempting to measure belief in redeemability in the broader context of a narrative approach to desistance.

Originality/value

This is the first time that a scale has been used to test the importance of a belief in redeemability quantitatively and to permit the use of multivariate analysis.
