Abstract Stocking with eggs has been widely used as a management measure to support degraded salmonid stocks. In Finland, Atlantic salmon and both sea-migrating and lake-migrating brown trout are stocked as eggs, alevins, fry, parr, and smolt, whereas trout are also stocked as mature fish. The aim of this stocking is to improve catches and to support collapsed spawning stocks. We assessed the success of stocking with brown trout eggs in a study of 17 Finnish boreal forest rivers, of which 9 were subject to egg stocking. All rivers contained some naturally spawning trout. In 16 rivers, including non-stocking years and unstocked rivers, egg stocking did not increase the total (wild and stocked) density of 0-year-old parr. However, those rivers with higher existing trout densities in non-stocking years seemed to benefit most from stocking, suggesting some role of river-specific extrinsic factors affecting egg-to-parr survival. In one river monitored for 14 years, only a weak correlation was found between the total density of 0-year-old parr and the number of eggs stocked. However, in nine parr samples from five rivers, the mean proportion of parr derived from stocked eggs was 40%. The mean survival to first autumn parr of egg-stocked and wild individuals was 1.0 and 3.3%, respectively. Probable reasons for the detected low to moderate impact of egg-stocking are (i) large variation in total parr density between years and rivers, (ii) small number of stocked eggs, (iii) placing egg boxes and egg pockets in unsuitable microhabitats, and (iv) unsuitable emergence time of egg-stocked individuals, or other extrinsic factors creating extra mortality. We recommend field and laboratory experiments to improve and standardize stocking methods, and monitoring the connection of wild spawning stocks and parr recruitment. Finally, we encourage fishery authorities to create clear management goals for threatened wild salmonid stocks.

We examined the relationship among team networks, leader-member exchange (LMX), and team identification in the workplace. Social network theory, social exchange theory, and social identity theory served as references for our theoretical propositions and analyses. We collected data from a sample of 223 teams of military personnel, serving in the artillery in West China. We found that the team networks had a significant effect on team identification. Further, the variance and the mean for LMX in teams interacted in influencing team identification (β =-.893, p < .01). Our findings indicated that creating productive networks in teams would be useful to enhance team identification, the effect of which may be carried on through to building exchange relationships between leader and follower.

Numerous studies have been conducted to explore the individual effects of organizational culture (OC) and supply chain management (SCM) practices on organizational performance (OP) in different settings. The aim of this study is to investigate the impact of OC and SCM on OP. The sample of the study consisted of 93 manufacturing firms in Jordan. Data were collected from employees and managers from different divisions using a reliable and valid measurement instrument. The findings confirm that both OC and SCM practices significantly predict OP. The current study is significant in reliably testing the relationship between SCM practices and OP; however, it is necessary to consider cultural assumptions, values and beliefs as the impact of OC on OP is greater than the impact of SCM practices. Based on the results, future studies should consider the moderating and mediating role of OC on the relationship between SCM practices and OP.

This study aims to test the influence of the senior management’s support as a moderating variable on the relationship between the independent factors (Training, Empowerment, Motivation and Communication) and the dependent variable (Performance of Employees). (SEM-AMOS) is used to test the impact of the moderating variable. Where it is depended on the method of sampling or analysis of what is known as multiple-groups analysis. The paragraphs of the senior management’s support variable are collected and divided into two groups according to the mean of the total paragraphs. In addition, according to the relative weights given to the paragraphs of the questionnaire, using a five- point’s Likert scale: 1= strongly disagree to 5 = strongly agree. The first group consisted of the grades less than the mean and it is considered as the group which is non-supporters of the existence of support. While the second group consisted of the grades higher than the mean and considered as the group which is a supporter of the existence of support. The study found that the model of study in the presence of the support of the senior management’s is appropriate for the second group and inappropriate in light of the lack of support by the senior management’s support for the first group.

There is great interest in the role of management control on theoretical and practical developments within the field of Inter-organizational Relations. This research aims to contribute at verifying how relationships between firms affect the management control tools used, as illustrated in a specific case: the relationship between the franchisor and its franchisees, which has not received much attention to date. As indicated by previous research, case studies can be helpful to determine the factors affecting the type of management control tools that should be established to manage inter-firm relationships.Results have found that the franchisor uses quantitative control mechanisms in order to avoid common types of opportunistic franchise behavior related to royalty payments and other financial requirements, as well as qualitative tools to assure the fulfilment of agreement-related conditions regarding knowhow, to resolve unexpected non-economic problems and to encourage personal relationship and trust. This study also provides an outline on franchisor-franchisee relationships in the model proposed by Van der Meer-Kooistra and Vosselman (2000). To test this model, the franchisor's perspective (outsourcer) has been taken into account as performed when building the model. Findings indicate that this relationship shows many similarities to the pattern based on bureaucracy and a few similarities to patterns based on trust.

This paper further investigates the Talent versus Luck (TvL) model described by [Pluchino et al. Talent versus luck: The role of randomness in success and failure, Adv. Complex Syst. 21 (2018) 1850014] which models the relationship between ‘talent’ and ‘luck’ on the impact of an individuals career. It is shown that the model is very sensitive to both random sampling and the choice of value for the input parameters. Running the model repeatedly with the same set of input parameters gives a range of output values of over 50% of the mean value. The sensitivity of the inputs of the model is analyzed using a variance-based approach based upon generating Sobol sequences of quasi-random numbers. When using the model to look at the talent associated with an individual who has the maximum capital over a model run it has been shown that the choice for the standard deviation of the talent distribution contributes to 67% of the model variability. When investigating the maximum amount of capital returned by the model the probability of a lucky event at any given epoch has the largest impact on the model, almost three times more than any other individual parameter. Consequently, during the analysis of the model results one must keep in mind the impact that only small changes in the input parameters can have on the model output.

Accessing financial services is considered one of the main challenges facing communities during crises. This research studies the role of using FinTech applications to build resilience during the COVID-19 pandemic. The research empirically examines the factors affecting Jordanian citizens’ intention to use FinTech applications. The sample of the research comprised 500 potential FinTech service users in Jordan. Based on the research conceptual model, five hypotheses were developed and tested using structural equation modeling techniques (SEM-PLS). The research results indicate that perceived benefits and social norms significantly affect the intention to use FinTech applications. However, it has been found that perceived technology risks do not significantly affect the intention to use FinTech applications. Moreover, the results also indicate that customer trust is significantly mediating the relationship between perceived risks and intention to use FinTech applications. FinTech service providers should insure that their products are easy to use, fulfill needs and protect consumers’ data in order to ensure trust, hence positively influencing consumer adoption.

The past few years have seen the development in Great Britain of the ‘contemporary comparison’ method for evaluating progeny tests of dairy sires (Macarthur, 1954; Robertson, Stewart and Ashton 1956). The final overall figure attached to a sire is the mean difference between the yield of his daughters and that of other heifers milking in the same herd in the same year, with due regard for the numbers of animals in the two groups. Although it has some imperfections in special cases, this is probably the most informative simple method of evaluating a sire for yield and, fortunately, one which could be easily integrated with the existing recording system. The method has been turned into a simple routine in the Bureau of Records of the Milk Marketing Board and several thousand bulls have now been evaluated. In this paper, we shall be mostly concerned to use this material to investigate the heritabilities of milk yield and fat content and the relationship between the two in the different breeds. The information that we shall use consists, for each bull, of the mean contemporary comparison, with its effective ‘weight’, and the average fat percentage of the daughters. Before we deal with the observed results, we should go into rather more detail into the nature of these two figures and into the factors affecting them.

PurposeThe purpose of this paper is to reframe human resources' (HR) systems and practices as HR signals drawing from conceptualizations of signals. The construct of the strength of signal is developed to quantify the attributional ability of HR signals. To examine the role of HR signals in influencing employee behaviours and firm performance, human resource management (HRM)-firm performance relationship is considered as a framework to develop a firm-level conceptual model which integrates factors affecting HR signals and its consequences.Design/methodology/approachThe paper examines the existing literature on the relationship between HRM and firm performance. In the process, the paper considers the concept of HR signal and makes a case for the strength of HR signal. Finally, the paper offers a conceptual model in order to link the antecedents and consequents of HR signals.FindingsThe paper offers a conceptual model to address the gaps in the relationship between HRM and firm performance. It also brings into focus an understanding of HRM as signals and its importance in understanding firm performance.Originality/valueThe paper enriches the existing literature by examining HRM as HR signals. It adds to the literature by considering the attributional ability of HR, through the construct of the strength of HR signals.

Arthritic Joints

Juvenile dog knee with chronic carrageenin-induced arthritis was studied under general anesthesia with 15-microns and 50-microns-sized microspheres (MS) to compare the distribution of absolute and weight-standardized blood flow in normal and arthritic limbs and to localize possible sites of arteriovenous (AV) shunting. Arthritic joints had severe synovial and capsular hyperemia. Absolute as well as standardized blood flow was increased in juxta-articular epiphyses and patella. Shafts were atrophic and had decreased absolute flow but normal standardized flow. However, redistribution of blood flow occurred among regions within the shafts, e.g., in metaphyses away from growth plates. The mean nonentrapment of 15-microns MS was 13.8% in arthritic limbs and 4.2% in control limbs. The uptake of 50-microns MS was lower than that of 15-microns MS in all bony flow compartments due to differences in their rheologic behavior in larger arteries. The relative distribution of 50-microns MS and 15-microns MS varied considerably among regions within bone. Arthritis caused a net shift in the uptake of 50-microns MS relative to that of 15-microns MS from central to subchondral epiphyseal bone, evidencing precapillary vasodilation, but the relationship was strictly unchanged when bones were examined in toto. This result militates against the hypothesis of AV shunting in arthritic bone.

This paper presents new analyses of data from two multicentre studies carried out by the WHO. The morbid risk of developing schizophrenia, as broadly defined by the Determinants of Outcome Study, was positively related to the mean daily range of temperature. The outcome of schizophrenia, as determined by the International Pilot Study of Schizophrenia, was found to be positively related to mean environmental temperature. Further studies are needed to examine the relationship of geographical and climatic variables to schizophrenia in order to complement what is already known about the role of sociocultural factors.
