Correlates of frequent gambling and gambling-related chasing behaviors in individuals with schizophrenia-spectrum disorders

Background and aims Published research on the relationship between disordered gambling and schizophrenia is limited. However, existing data suggest that individuals with schizophrenia/schizoaffective disorder may have a high prevalence of co-occurring disordered gambling. As such, effective strategies for screening and assessing gambling-related problems in individuals with psychosis are needed. The goal of this study was to explore the correlates of increased gambling frequency and chasing behavior, a hallmark feature of gambling disorder, in a sample of individuals with schizophrenia and schizoaffective disorders. Methods Data from 336 participants who met DSM-IV criteria for schizophrenia or schizoaffective disorder were used to examine differences between non-gamblers, infrequent gamblers, frequent gamblers who do not report chasing, and frequent gamblers who report chasing on a variety of associated features and symptoms of schizophrenia and disordered gambling. Results and discussion The results of the study support the conclusion that chasing behavior in individuals with schizophrenia/schizoaffective disorder lies on a continuum of severity, with more frequent gamblers endorsing greater chasing. Chasing was also associated with indicators of lower functioning across co-occurring disorders, such as greater problems with alcohol and drugs, greater gambling involvement, and a family history of gambling problems. The findings from the study suggest the utility of screening for chasing behavior as a brief and efficient strategy for assessing risk of gambling problems in individuals with psychotic-spectrum disorders

Agrarian Policy of the Region in Terms of Economic Development Innovation

The relevance of the topic lies in the difficult situation of the agricultural sector, which explains the General decline in production, broken economic ties, lack of scientifically grounded concept of legal base for implementation of market reforms, and innovation mechanism, creating economic conditions for expanded reproduction, which led to the deconstruction of all existing systems. The current situation in the agricultural sector is characterized by crisis factors. The main cause of imbalance of the system of agriculture was a radical transformation of the ownership of the means of production. Changed organizational-legal forms of collective enterprises, was developed the sector of individual entrepreneurship in rural areas. Agriculture with its labor-intensive production may allow one of the most acute social problems - employment. Consequently, there is the problem of the development of the mechanism of economic relations between the government, stakeholders in the agricultural production and commercial structures for the development of new adequate approaches to the provision of investment resources to the agricultural sector of the economy. Thus the expansion of the scope of economic methods of state return release of funds to the agricultural sector can become a real source of maintaining their resource potential as the most economical and effective innovative way to support the industry.

Assessment of the role of the state in the management of mineral resources

Mineral resources as natural capital can be transformed into human, social and physical capital, that guarantees the sustainable development of a country, exclusively through professional public management. Public management of a country's mineral resource potential is seen as an element of transnational governance. Regulation involves the use of laws, rules and regulations within the jurisdictional and sectoral capabilities of the state, minimizing its involvement as a producer. The features of the ideology of economic liberalism, which polarizes the societies of raw material producing countries by imposing austerity, as well as lowering trade barriers have been studied. The analysis of the influence of the radical new order of neoliberal world ideology on the development of the extractive sector and the strengthening of state regulation has been presented

Parquet solution for a flat Fermi surface

We study instabilities occurring in the electron system whose Fermi surface has flat regions on its opposite sides. Such a Fermi surface resembles Fermi surfaces of some high-$T_c$ superconductors. In the framework of the parquet approximation, we classify possible instabilities and derive renormalization-group equations that determine the evolution of corresponding susceptibilities with decreasing temperature. Numerical solutions of the parquet equations are found to be in qualitative agreement with a ladder approximation. For the repulsive Hubbard interaction, the antiferromagnetic (spin-density-wave) instability dominates, but when the Fermi surface is not perfectly flat, the $d$-wave superconducting instability takes over.Comment: REVTeX, 36 pages, 20 ps figures inserted via psfig.

Midgap edge states and pairing symmetry of quasi-one-dimensional organic superconductors

The singlet s-, d- and triplet p-wave pairing symmetries in quasi-one-dimensional organic superconductors can be experimentally discriminated by probing the Andreev bound states at the sample edges. These states have the energy in the middle of the superconducting gap and manifest themselves as a zero-bias peak in tunneling conductance into the corresponding edge. Their existence is related to the sign change of the pairing potential around the Fermi surface. We present an exact self-consistent solution of the edge problem showing the presence of the midgap states for p_x-wave superconductivity. The spins of the edge state respond paramagnetically to a magnetic field parallel to the vector d that characterizes triplet pairing.Comment: 6 pages, 4 figures. V.2: New section on spin response is added and references are updated. V.3: Final version accepted to PRB. Typos are corrected and important note is added in proof

Chasing the loss: Factors that predict within- and between-session chasing in gamblers

One of the hallmark features of disordered gambling is ‘chasing’, defined as an urge to continue playing within a single gaming session or come back at another time to attempt to recover lost money. To date, limited research has been conducted to delineate specific predictors of increased chasing behaviour in both disordered and social gamblers. The present study attempted to answer two questions: 1) which personality, physiological, and cognitive variables predict increased within- and between- session chasing behaviour in disordered and social gamblers? 2) In what ways do disordered and social gamblers differ with regard to predictors of chasing? 111 participants recruited in the community, divided into social and disordered gamblers, gambled on a realistic slot machine with predetermined outcomes. Variables relating to disordered gambling severity, dissociation, emotional vulnerability, cognitive distortions, impulsivity, substance use, and craving for gambling and other substances were assessed as predictors of between- and within-session chasing. Results support the association of chasing behaviour with dissociation, gambling problem severity, emotional vulnerability, and impulsivity. However, inconsistencies in some results point to difficulties in reliability of operationalizing chasing. The results also put in question the validity of using retrospective self-report to assess chasing. The overall findings support chasing as operating on a continuum of severity with social gamblers chasing in limited amounts and disordered gamblers chasing in greater amounts. In addition, qualitative feedback from participants challenges the utility of in-lab gambling as a proxy of real-world gambling conditions. Implications for research, policy and treatment of disordered gambling are discussed and recommendations for future research are provided

Особливості ультрасонографічних ознак патологічних змін у структурі периартикулярних тканин плечового суглоба у хворих із різними проявами больового синдрому

Tendonitis of muscles which provide movements in the shoulder joint (SJ), osteochondrosis of cervical or thoracic spine, secondary vertebrogenic radiculopathy commonly is cause pain and limitation of motor activity in the shoulder girdle area. Objective: to identify the peculiarities of pathological changes in anatomical structures of SJ at pain syndrome at various nosology. Methods: 206 patients (18–65 years old) were examined and divided into three groups: I — control, II — shoulder impingement syndrome (SIS) at spinal degenerative disc disease, III — SIS of unknown etiology. Ultrasound data were analyzed. Results: it was found that in healthy people there were age-related ultrasound changes in the structure of tendons, ligaments, muscles and SJ cartilages which did not cause discomfort. Changes were found in 10 % of people in a subgroup of 30–40 years of age, and in 30–45 % in older ones. Thicknesses of the capsule, ten­dons, ligaments and muscles were almost equal (symmetrical) on contralateral joints. The absolute difference in soft-tissue structures’ thickness did not exceed 0.2 mm, the asymmetry coefficient was 0.96. In group II, there were almost no changes in the structure of SJ’s periarticular tissues. The absolute difference in anatomical structures’ thickness was 0.2 mm, the asymmetry coefficient of thickness of the affected and intact joints’ anatomical structures was more than 0.95. In group III, the largest disorders were observed: the echogenicity of affected SJ structures was reduced in more than 90 % of patients; in one third — a heterogeneous structure with hyperechoic inclusions was observed. The absolute difference in thickness of anatomical structures on affected limb comparing with those on the healthy one was more than 0.5 mm, the asymmetry coefficient was less than 0.95. Conclusions: using obtained data, we divided the group with SIS during initial examination, according to the presence of structural changes in the SJ’s periarticular tissues, in order to choose the treatment tactics subsequently.Частой причиной болевого синдрома и ограничения двигательной активности в плечелопаточной области являются тендиниты мышц, обеспечивающих движения в плечевом суставе (ПС), остеохондроз шейного или грудного отделов позвоночника, вторичная вертеброгенная радикулопатия. Цель: выявить особенности патологических изменений анатомических структур ПС при болевом синдроме в области плеча на фоне различных нозологий. Методы: обследовано 206 человек (18–65 лет), которых разделили на три группы: I — контрольная, II — плечелопаточный болевой синдром (ПЛБС) на фоне остеохондроза, III — ПЛБС неясной этиологии. Анализировали данные ультразвукового исследования (УЗИ). Результаты: установлено, что у практически здоровых людей с возрастом изменяются УЗИ-характеристики структуры сухожилий, связок, мышц и хрящей ПС, которые не вызывают чувство дискомфорта. Изменения обнаружены у 10 % людей в возрасте 30–40 лет, а старше 41 года — у 30–45 %. Толщина капсулы, сухожилий, связок и мышц была практически симметричной на контралатеральных суставах. Абсолютная разница толщины мягкотканных структур не превышала 0,2 мм, коэффициент асимметрии — 0,96. Во II группе изменений структуры периартикулярных тканей ПС практически не было. Абсолютная разница толщины анатомических структур — 0,2 мм, коэффициент асимметрии толщины анатомических структур пораженного и интактного суставов больше 0,95. В III группе выявлены наибольшие нарушения: более чем у 90 % больных эхогенность пораженных структур ПС была снижена, у трети — структура неоднородная с гиперэхогенными включениями. Абсолютная разница толщины анатомических структур на больной конечности составила больше 0,5 мм, чем на здоровой, коэффициент асимметрии — меньше 0,95. Выводы: полученные данные позволяют на первичном обследовании разделить группу с ПЛБС по наличию структурных изменений в периартикулярных тканях ПС для дальнейшего выбора тактики лечения.Найчастішою причиною больового синдрому й обмеження рухової активності в плечолопатковій ділянці вважають тендиніти м’язів, які забезпечують рухи в плечовому суглобі (ПС), остеохондроз шийного або грудного відділів хребта, вторинна вертеброгенна радикулопатія. Мета: дослідити особливості патологічних змін анатомічних структур ПС за умов больового синдрому в ділянці плеча на фоні різних нозологій. Методи: обстежено 206 осіб (18–65 років), яких розділили на три групи: I — контрольна, II — плечолопатковий больовий синдром (ПЛБС) на фоні остеохондрозу, III — ПЛБС неясної етіології. Аналізували дані ультразвукового дослідження (УЗД). Результати: встановлено, що у практично здорових людей із віком змінюються УЗ-характеристики структури сухожиль, зв’язок, м’язів і хрящів ПС, які не призводять до відчуття дискомфорту. Зміни виявлені у 10 % людей у віці 30–40 років, а в старших за 41 рік — у 30–45 %. Товщина капсули, сухожиль, зв’язок і м’язів була практично симетричною на контралатеральних суглобах. Абсолютна різниця товщини м’якотканинних структур не перевищувала 0,2 мм, коефіцієнт асиметрії — 0,96. У II групі змін структури периартикулярних тканин ПС практично не було. Абсолютна різниця товщини анатомічних структур — 0,2 мм, коефіцієнт асиметрії товщини анатомічних структур ураженого й інтактного суглобів більше ніж 0,95. У III групі виявлені найбільші порушення: у понад 90 % хворих ехогенність уражених структур ПС була зниженою, у третини — структура неоднорідною з гіперехогенними включеннями. Абсолютна різниця товщини анатомічних структур на хворий кінцівки склала понад 0,5 мм, ніж на здоровій, коефіцієнт асиметрії — менше ніж 0,95. Висновки: отримані результати дозволяють на первинному обстеженні розділити групу з ПЛБС за наявністю структурних змін у периартикулярних тканинах ПС для подальшого вибору тактики лікування
