Consumers’ reactions to variety reduction in grocery stores: a freedom of choice perspective
Authors: Argouslidis Paraskevas , Skarmeas Dionysis , Kühn Antonios , Mavrommatis Alexis 
Published: August 2018

Purpose
This paper aims to propose a framework for psychological reactance–triggered adverse effects of variety reductions in grocery product categories on shoppers’ patronage intentions.

Design/methodology/approach
The paper tests this framework in two field studies with European shoppers.

Findings
Participants perceived mild (let alone aggressive or conspicuous) variety reductions as a threat to their prior freedom of choice (i.e. a precondition for the occurrence of domain-specific reactance). Through lower satisfaction with the reduced variety and anger towards the grocer, this threat, in turn, fostered adverse patronage intentions. Such effects depended on product category nature (utilitarian vs hedonic) and shoppers’ intrinsic need for variety, attitude towards private-label items and general proclivity towards experiencing reactance.

Research limitations/implications
By applying psychological reactance theory to a variety reduction context, this paper offers new implications for assortment reduction research. Certain limitations call for future reactance theory–framed inquiry.

Practical implications
The findings caution against traditional grocers’ drastic variety reduction policy and highlight conditions enabling assortment rationalisation without severely affecting freedom of choice.

Originality/value
Drawing on notions such as “the tyranny of choice”, critics have urged traditional grocers to drastically reduce variety. However, this paper shows that shoppers perceive variety reductions as threats to their prior freedom, which traditional grocers themselves educated them to expect and enjoy.
Institutional practices and vulnerability of shrimp fry catchers in the south-west region of Bangladesh
Authors: Moni Nurun Naher , Haider Mohammed Ziaul , Al Masud Md Mahedi 
Published: August 2018

Purpose
The purpose of this paper is to provide a better understanding of the dynamics of institutional practices, socio-economic status and vulnerability of shrimp fry catchers in the south-west region of Bangladesh.

Design/methodology/approach
This study draws on primary research conducted through face-to-face interviews with women fry collectors in the south-west region of Bangladesh. This study attempts to identify the nature and extent of the impact of institutional practices on the women engaged in catching fry regarding their positioning within the institutional framework.

Findings
In the coastal region of Bangladesh, the shrimp sector has opened up economic opportunities for women in terms of access to income and employment. However, women have to make a trade-off between employment gain in terms of wage and health hazards caused due to poor working conditions. The findings of the study indicate that shrimp fry catching, complemented by other sources of income, can only help women to survive. The study also finds that the vulnerability of the fry collectors is the end result of mutually interacting institutional practices under different institutional domains. Accordingly, recommendations are made with a view to effectively utilizing social capital at the community level, which will be particularly helpful in raising fry catchers’ voice in the local political arena and strengthening their position in the marketplace. Due to the higher preferences of buyers towards wild fry and the participation of a huge number of people in fry collecting, this study suggests rethinking government intervention in this regard.

Originality/value
This is original research focusing on the underlying structural and institutional factors behind the marginalization and vulnerability of women and devising policies that will enable modification of the factors that restrain women.
Measuring the interdisciplinarity of Big Data research: a longitudinal study
Authors: Hu Jiming , Zhang Yin 
Published: August 2018

Purpose
The purpose of this paper is to measure the degree of interdisciplinary collaboration in Big Data research based on the co-occurrences of subject categories using Stirling’s diversity index and specialization index.

Design/methodology/approach
Interdisciplinarity was measured utilizing the descriptive statistics of disciplines, network indicators showing relationships between disciplines and within individual disciplines, interdisciplinary communities, Stirling’s diversity index and specialization index, and a strategic diagram revealing the development status and trends of discipline communities.

Findings
Comprehensively considering all results, the degree of interdisciplinarity of Big Data research is increasing over time, particularly, after 2013. There is a high level of interdisciplinarity in Big Data research involving a large number of disciplines, but it is unbalanced in distribution. The interdisciplinary collaborations are not intensive on the whole; most disciplines are aggregated into a few distinct communities with computer science, business and economics, mathematics, and biotechnology and applied microbiology as the core. Four major discipline communities in Big Data research represent different directions with different development statuses and trends. Community 1, with computer science as the core, is the most mature and central to the whole interdisciplinary network. Accounting for all network indicators, computer science, engineering, business and economics, social sciences, and mathematics are the most important disciplines in Big Data research.

Originality/value
This study deepens our understanding of the degree and trend of interdisciplinary collaboration in Big Data research through a longitudinal study and quantitative measures based on two indexes. It has practical implications to study and reveal the interdisciplinary phenomenon and characteristics of related developments of a specific research area, or to conduct comparative studies between different research areas.
Genetic dissection of bull fertility in US Jersey dairy cattle
Authors: Rezende F. M. , Dietsch G. O. , Peñagaricano F. 
Published: August 2018

SummaryThe service sire has been recognized as an important factor affecting herd fertility in dairy cattle. Recent studies suggest that genetic factors explain part of the difference in fertility among Holstein sires. The main objective of this study was to dissect the genetic architecture of sire fertility in US Jersey cattle. The dataset included 1.5 K Jersey bulls with sire conception rate (SCR) records and 96 K single nucleotide polymorphism (SNP) markers spanning the whole genome. The analysis included whole‐genome scans for both additive and non‐additive effects and subsequent functional enrichment analyses using KEGG Pathway, Gene Ontology (GO) and Medical Subject Headings (MeSH) databases. Ten genomic regions located on eight different chromosomes explained more than 0.5% of the additive genetic variance for SCR. These regions harbor genes, such as PKDREJ, EPB41L2, PDGFD, STX2, SLC25A20 and IP6K1, that are directly implicated in testis development and spermatogenesis, sperm motility and the acrosome reaction. In addition, the genomic scan for non‐additive effects identified two regions on BTA11 and BTA25 with marked recessive effects. These regions harbor three genes—FER1L5, CNNM4 and DNAH3—with known roles in sperm biology. Moreover, the gene‐set analysis revealed terms associated with calcium regulation and signaling, membrane fusion, sperm cell energy metabolism, GTPase activity and MAPK signaling. These gene sets are directly implicated in sperm physiology and male fertility. Overall, this integrative genomic study unravels genetic variants and pathways affecting Jersey bull fertility. These findings may contribute to the development of novel genomic strategies for improving sire fertility in Jersey cattle.
Machine learning entanglement freedom
Authors: Spillard Samuel , Turner Christopher J. , Meichanetzidis Konstantinos 
Published: August 2018

Quantum many-body systems realize many different phases of matter characterized by their exotic emergent phenomena. While some simple versions of these properties can occur in systems of free fermions, their occurrence generally implies that the physics is dictated by an interacting Hamiltonian. The interaction distance has been successfully used to quantify the effect of interactions in a variety of states of matter via the entanglement spectrum [C. J. Turner, K. Meichanetzidis, Z. Papic and J. K. Pachos, Nat. Commun. 8 (2017) 14926, Phys. Rev. B 97 (2018) 125104]. The computation of the interaction distance reduces to a global optimization problem whose goal is to search for the free-fermion entanglement spectrum closest to the given entanglement spectrum. In this work, we employ techniques from machine learning in order to perform this same task. In a supervised learning setting, we use labeled data obtained by computing the interaction distance and predict its value via linear regression. Moving to a semi-supervised setting, we train an autoencoder to estimate an alternative measure to the interaction distance, and we show that it behaves in a similar manner.

Published: August 2018

BackgroundExercise improves cardiorespiratory fitness (CRF) and reduces depressive symptoms in people with depression. It is unclear if changes in CRF are a predictor of the antidepressant effect of exercise in people with depression.AimsTo investigate whether an increase in CRF is a predictor of depression severity reduction after 12 weeks of exercise (trial registration: DRKS study ID, DRKS00008745).MethodThe present study includes participants who took part in vigorous (n= 33), moderate (n= 38) and light (n= 39) intensity exercise and had CRF information (as predicted maximal oxygen uptake,V̇O2max) collected before and after the intervention. Depression severity was measured with the Montgomery–Åsberg Depression Rating Scale (MADRS).V̇O2max(L/min) was assessed with the Åstrand–Rhyming submaximal cycle ergometry test. The main analysis was conducted pooling all exercise intensity groups together.ResultsAll exercise intensities improvedV̇O2maxin people with depression. Regardless of frequency and intensity of exercise, an increase in post-treatmentV̇O2maxwas significantly associated with reduced depression severity at follow-up (B= −3.52, 95% CI −6.08 to −0.96); adjusting for intensity of exercise, age and body mass index made the association stronger (B= −3.89, 95% CI −6.53 to −1.26). Similarly, increasedV̇O2maxwas associated with higher odds (odds ratio = 3.73, 95% CI 1.22–11.43) of exercise treatment response (≥50% reduction in MADRS score) at follow-up.ConclusionsOur data suggest that improvements inV̇O2maxpredict a greater reduction in depression severity among individuals who were clinically depressed. This finding indicates that improvements inV̇O2maxmay be a marker for the underpinning biological pathways for the antidepressant effect of exercise.Declaration of interestNone.
Acute hip fracture surgery anaesthetic technique and 30-day mortality in Sweden 2016 and 2017: A retrospective register study
Authors: Gremillet Caroline , Jakobsson Jan G. 
Published: August 2018

Background: Hip fractures affect 1.6 million patients yearly worldwide, often elderly with complex comorbidity. Mortality following surgery for acute hip fracture is high and multifactorial; high age, comorbidities and complication/deterioration in health following surgery. Whether the anaesthesia technique affects the 30-day mortality rate has been studied widely without reaching a consensus. The primary aim of this study was to determine anaesthetic techniques used in Sweden and their impact on the 30-day mortality rate in elderly undergoing acute hip fracture surgery. Other aims were to study the impact of age, gender, ASA class, fracture type and delay in surgery on the 30-day mortality rate. Methods: Data from 13,649 patients ≥50 years old who had undergone acute hip fracture surgery and been reported to Swedish perioperative register (SPOR) between 2016 and 2017 were analysed. Results: The most commonly used anaesthetic technique was neuraxial anaesthesia (NA; 11,257, 82%), followed by general anaesthesia (GA; 2,190, 16%) and combined general and neuraxial anaesthesia (CA; 202, 1.5%) out of the 13,649 studied. The 30-day mortality rate was 7.7% for the entire cohort; GA 7.8%, NA 7.7% and CA 7.4%. Mortality was higher in elderly patients, those with a high ASA class, pertrochanteric fracture and males. Conclusions: The present study showed that NA is by far the most common anaesthetic technique for acute hip fracture surgery in Sweden. However, the anaesthetic technique used during this type of surgery had no impact on the 30-day mortality rate in patients. Increasing age, ASA class and male gender increased the 30-day mortality.
A teoria política de Marx: uma totalidade orgânica | Marx’s political theory: an organic whole
Authors: Polese Pablo 
Published: August 2018

Apresenta-se aqui uma leitura dos principais traços da teoria política de Marx. Esta é entendida como uma totalidade orgânica na qual cada elemento impõe necessariamente sua articulação e mediação com os demais. Ao delinear nestes termos o legado político de Marx, pretende-se contribuir no sentido da elaboração de uma teoria da transição para além do sistema do capital. Defende-se que esta precisa, necessariamente, incorporar de forma crítica o legado das teorias da transição clássicas, em especial as elaboradas no esteio da Revolução Russa de 1917, e também aquelas que foram elaboradas mais recentemente, com a vantagem de poderem versar sobre a experiência soviética que formalmente chegou ao fim em 1991. Por conta disso e por afinidades teóricas, o intérprete marxista privilegiado no texto é István Mészáros.Palavras-Chave: Karl Marx; revolução; transição socialista; teoria política; comunismo; István Mészáros. Abstract –It is presented here a reading of the main features of Marx's political theory. This is understood as an organic whole in which each element necessarily imposes its articulation and mediation with the others. In outlining in these terms Marx's political legacy, this article is intended to contribute towards the elaboration of a theory of transition beyond the capital system. It is argued that this transition necessarily needs to incorporate in a critical way the legacy of classical transition theories, especially those elaborated in the wake of the Russian Revolution of 1917, and also those that have been elaborated more recently, with the advantage of being able to deal with the Soviet experience that formally came to an end in 1991. Because of this and theoretical affinities, the Marxist interpreter privileged in the text is István Mészáros.Keywords: Karl Marx; revolution; socialist transition; political theory; communism; István Mészáros.
Pobreza e desigualdade social: fundamentos sociais e históricos | Poverty and social inequality: social and historical foundations
Authors: Carvalho Luciene Ferreira Mendes de 
Published: August 2018

O presente trabalho tem como objetivo a análise da pobreza e desigualdade social na sociedade capitalista contemporânea, demonstrando os seus aspectos estruturais, considerados a partir da lógica de reprodução do capital. Apresenta uma análise crítica e histórica acerca da pobreza e da desigualdade social, fundamentada no método materialista dialético elaborado por Karl Marx. Nesse sentido, compreende os processos históricos a partir dos modos de produção social, ou seja, da forma como os homens se organizam para produzir os bens necessários à satisfação de suas necessidades, sendo, portanto, o trabalho humano uma categoria central. Inicialmente, apresentam-se as formas de organização societária pré-capitalistas, determinadas pelo primitivismo, escravismo e feudalismo, a fim de evidenciar que a pobreza e a desigualdade social são construções sociais e históricas e nesse sentido, compreender os percursos trilhados para se chegar ao momento atual. Em seguida, evidencia-se o modo de produção capitalista, demonstrando que a pobreza e a desigualdade social são inerentes à lógica da acumulação, portanto são geradas e não dadas naturalmente. Palavras-chave: Pobreza; Desigualdade Social; Trabalho; Capitalismo. Abstract — The present work has the objective of analyzing poverty and social inequality in contemporary capitalist society, demonstrating its structural aspects, considered from the logic of reproduction of capital. It presents a critical and historical analysis of poverty and social inequality, based on the dialectical materialist method elaborated by Karl Marx. In this sense, it understands historical processes from the modes of social production, that is, from the way men organize themselves to produce the goods necessary to satisfy their needs, and therefore, human work is a central category. Initially, the pre-capitalist forms of societal organization, determined by primitivism, slavery and feudalism, are presented in order to show that poverty and social inequality are social and historical constructions and, in this sense, to understand the current moment. Next, the capitalist mode of production is shown, demonstrating that poverty and social inequality are inherent in the logic of accumulation, so they are generated and not given naturally.Keywords: Poverty; Social inequality; Work; Capitalism.

Dalālah al-Khafī wa Āliyāt al-Ijtihād: Dirāsah Uṣuliyyah bi Iḥālah Khāṣṣah ilā Qaḍiyah al-Qatl al-Raḥim
Authors: Anwar Syamsul 
Published: August 2018

This article deals with an uṣūlī concept known among the Hanafi legal theoretician under the name of dalālāt al-khāf (the denotation of an obscure text) and its relation to the mechanism of ijtihād with special reference to the case of euthanasia. The author examines the meaning of the obscure text (al-khāfiy) and discusses the mechanism followed by the uṣūlī in clarifying the ambiguity in it, taking euthanasia as an example. From this, the author concludes that the process of legal reasoning in founding out a legal rule for a case involves three poles which have dialectical relations to one another: the text, the reality, and the objective of law. The text with its symbolic characteristic and its relying upon generalization and abstraction in expressing an object enables the mujtahid to add a new meaning to it and this meaning is produced through an adequate understanding of the case and the spatio-temporal space in which it happens in the one hand and through considering the objective of law as meaning space on the other hand. The reality of the case shades light in our understanding of the text, while the text in the same time gives us a clear orientation in coping with the reality.
Salik Buta: Aliran Tasawuf Aceh Abad XX
Authors: Muchsin Misri A 
Published: August 2018

This article examines the Sufi movement in Aceh by looking at its continuity since the 16th -17th century, as its golden age, to the 20th century. Based on the fact that Abdullah Ujong Rimba's explanation is considered representative, his books are taken as primary sources while others are secondary. Based on Abdullah Ujong Rimba's explanation, Salik Buta is a sect of Sufism in Aceh in the 20th century. This sect is practiced in several of center in Aceh. Historically, the doctrine of this sects is continuation and modification of Wahḍat al-Wujūd's doctrines established since 16th century. The doctrine of Salik Buta are different from those of popular Sufism. Thus, Salik Buta is considered heterodox and criticized by ulama, as Abdullah Ujong Rimba. From Abdullah Ujong RImba's criticism, it can be conclude that his thought based on syari'at or Fiqih orientation, instead of the perspective of Sufism.

Published: August 2018

Background: Insomnia is a sleep disturbance which commonly occurs in haemodialysis patients. Some factors contribute to insomnia in dialysis patients such as demographic, biological, psychological, lifestyle, and dialysis factors. However, there are limited studies which investigate the relating factors of insomnia in haemodialysis patients in Indonesia.Purpose: This study aimed to analyze the relating factors of insomnia in haemodialysis patients in Semarang, Central Java, Indonesia.Methods: This study was a cross-sectional study which involved 102 samples recruited by consecutive sampling technique from two dialysis units in Semarang, Central Java. Data were collected by questionnaires and analyzed using Chi-square and multiple logistic regression to know the most relating factors of insomnia.Results: The result showed that insomnia occurred in 63 respondents (61.8%). Further analysis indicated that insomnia was related to anxiety (p=0.034, OR=2.36) and age (p=0.049; OR=1.75). There was no relationship between insomnia and the other factors such as gender, education level, occupation status, marital status, haemoglobin level, smoking and coffee consumption habit, and dialysis factor (period of dialysis). Moreover, anxiety was the most relating factors of insomnia among haemodyalsis patients.Conclusion: This study concluded that anxiety and age were independent factors related to insomnia. This study recommends that anxiety screening should be performed on haemodialysis patients. Anxiety in haemodialysis patients needs to be treated properly so that it will not develop into insomnia.
Average fibre length as a measure of the amount of long fibres in mechanical pulps – ranking of pulps may shift
Authors: Ferritsius Olof , Ferritsius Rita , Rundlöf Mats 
Published: August 2018

Abstract
The purpose of this study was to investigate the applicability of different ways of calculating the average fibre length based on length measurements of individual particles of mechanical pulps. We have found that the commonly used average length-weighted fibre length, which is based on the assumption that coarseness is constant for all particles, as well as the arithmetic average, may lead to erroneous conclusions in real life as well as in simulations when used as a measure of the amount of long fibres. The average length-length-weighted fibre length or a weighting close to that, which to a larger extent suppresses the influence of shorter particles, is a relevant parameter of the “length” factor, i. e. amount of long fibres. Our findings are based on three studies: refining of different assortments of wood raw material in a mill; data from LC refining in mill of TMP, including Bauer McNett fractionation; mixing of pulps with different fibre length distributions. If the acceptable average fibre length for different products can be lowered, the possibility of reducing the specific energy input in refining will increase. Therefore, we need a reliable and appropriate way to assess the “length” factor.
