Struggling with happiness: A pathway leading depression to gambling disorder

A number of studies have suggested that depressive mood might lead to the development and/or maintenance of a gambling disorder (GD). The pathways by which such relationships are fostered may involve deficits in emotional regulation capacity and dysfunctional coping styles. This study aims to explore the role played by depressive symptomatology and the regulation of positive emotion in GD. We administered the South Oaks Gambling Inventory (SOGS, Lesieur and Blume in Am J Psychiatry 144(9):1184\u20131188, 1987), the 21-item Depression Anxiety Stress Scale (DASS-21, Lovibond and Lovibond in Manual for the depression anxiety stress scales. Psychology Foundation, Sydney, 1995) and the Kill-joy Thinking subscale of the Ways of Savouring Checklist (WOSC, Bryant and Veroff in Savoring: a new model of positive experience. Lawrence Erlbaum, Mahwah, 2007) to a sample of pathological gamblers (n = 91) and a sample of community participants (n = 105). The pathological gamblers scored higher on the DASS-21 subscales and obtained higher scores on the Kill-joy Thinking subscale of the WOSC compared to the controls. Moreover, the SOGS scores positively correlate with the DASS-21 subscales, and with the Kill-Joy Thinking measure. Finally, it is evident that Kill-joy Thinking fully mediates the relationship between depressive symptomatology and GD severity. Our results further confirm the roles of depression, anxiety and stress in GD. Moreover, this is the first study to explore the mediating role of dampening processes in the relationship between depression and GD. Future lines of research are also discussed

Predicting soil moisture conditions for arable free draining soils in Ireland under spring cereal crop production

peer-reviewedTemporal prediction of soil moisture and evapotranspiration has a crucial role in agricultural and environmental management. A lack of Irish models for predicting evapotranspiration and soil moisture conditions for arable soils still represents a knowledge gap in this particular area of Irish agro-climatic modelling. The soil moisture deficit (SMD) crop model presented in this paper is based on the SMD hybrid model for Irish grassland (Schulte et al., 2005). Crop and site specific components (free-draining soil) have been integrated in the new model, which was calibrated and tested using soil tension measurements from two experimental sites located on a well-drained soil under spring barley cultivation in south-eastern Ireland. Calibration of the model gave an R2 of 0.71 for the relationship between predicted SMD and measured soil tension, while model testing yielded R2 values of 0.67 and 0.65 (two sites). The crop model presented here is designed to predict soil moisture conditions and effective drainage (i.e., leaching events). The model provided reasonable predictions of soil moisture conditions and effective drainage within its boundaries, i.e., free-draining land used for spring cereal production under Irish conditions. In general, the model is simple and practical due to the small number of required input parameters, and due to model outputs that have good practical applicability, such as for computing the cumulative amount of watersoluble nutrients leached from arable land under spring cereals in free-draining soils

Communication: key factor in multidisciplinary system design

System design research often looks at ways to model the system that is developing. Many modelling techniques and model representations exist. Another aspect these models can be used for is to enable, facilitate and improve communication among the developers during the process. The young System Design Group at the faculty of Engineering Technology of the University of Twente, the Netherlands, aims at focusing on this communication aspect in system design.\ud In the paper, a few finished and running projects undertaken in close cooperation with industry are described concisely. From these projects three research themes are derived. These are: creation of high-level models, combining model representations and condense information. The paper ends with plans for future research

Electromagnetic analysis and performance comparison of fully 3D-printed antennas

In this work, the possibility of directly prototyping antennas by exploiting additive manufacturing 3D-printing technology is investigated. In particular, the availability of printable filaments with interesting conductive properties allows for printing of even the antenna conductive elements. Three samples of a 2.45 GHz microstrip patch antenna have been 3D-printed by using different approaches and materials, and their performance evaluated and compared. In particular, the same dielectric substrate printed in polylactic acid (PLA) has been adopted in all cases, whilst copper tape and two different conductive filaments have been used to realize the conductive parts of the three antenna samples, respectively. Even if an expected radiation efficiency reduction has been observed for the conductive filament case, the comparative analysis clearly demonstrates that 3D-printing technology can be exploited to design working fully-printed antennas, including the conductive parts

Agriculture, meteorology and water quality in Ireland: a regional evaluation of pressures and pathways of nutrient loss to water

peer-reviewedThe main environmental impact of Irish agriculture on surface and ground water quality is the potential transfer of nutrients to water. Soil water dynamics mediate the transport of nutrients to water, and these dynamics in turn depend on agro-meteorological conditions, which show large variations between regions, seasons and years. In this paper we quantify and map the spatio-temporal variability of agro-meteorological factors that control nutrient pressures and pathways of nutrient loss. Subsequently, we evaluate their impact on the water quality of Irish rivers. For nitrogen, pressure and pathways factors coincide in eastern and southern areas, which is reflected in higher nitrate levels of the rivers in these regions. For phosphorus, pathway factors are most pronounced in north-western parts of the country. In south-eastern parts, high pressure factors result in reduced biological water quality. These regional differences require that farm practices be customised to reflect the local risk of nutrient loss to water. Where pathways for phosphorus loss are present almost year-round—as is the case in most of the north-western part of the country—build-up of pressures should be prevented, or ameliorated where already high. In south-eastern areas, spatio-temporal coincidence of nutrient pressures and pathways should be prevented, which poses challenges to grassland management

A robust wearable textile SIW RFID antenna

A wearable textile Radio Frequency Identification (RFID) tag realized on a substrate integrated waveguide cavity is presented, operating in the European UHF RFID frequency band. The antenna shows a very good isolation with respect to the human body, and a satisfactory robustness to antenna-body distance variations. The resulting tag is very compact, since its size has been reduced by exploiting the symmetry of a SIW cylindrical resonant cavity and obtaining an eighth mode SIW antenna, and can be produced at low-cost through simple manufacturing processes

An Exploration of Home Attachment Representations using an Adaptation of Adult Attachment Interview: Preliminary Data on the Home Attachment Interview

Background: In analysing the literature on household as a physical structure strongly linked to cultural and affective aspects, as well as to universal central psychological needs, a universe of meanings was found. The household, conceptualised as home and safe shelter that contains and protects, but also as a favourite place where the most important relationships of each human being unfold, suggests to use attachment theory perspective as a potentially useful framework to conceptualize the construct of home attachment. However, this perspective needs to be further investigated in order to understand its complex nature. Therefore, this pilot study aims to investigate how individuals represent their own homes according to their feelings and emotions related to their household.Methods: A qualitative-quantitative survey has been carried out with 50 adults (50% females) divided into five different age groups (from late adolescence to old age). An adapted version of the Adult Attachment Interview, the Home Attachment Interview, was administered.Results: Analysis identified the relevant aspects that distinguish the "house" as a physical structure, and the "home", that symbolically encloses emotional and affective experiences suggesting a perception of the "house" as "home", being a special place characterised by a strong attachment relationship connoted symbolically and affectively.Conclusions: Attachment theoretical and methodological tools used in the study appear especially useful to investigate and understand the construct of home attachment
