Paid Parental Leave: An Employee Right or Still An Ideal? An Analysis of the Situation in Québec in Comparison with North America

Over recent years, parental leave policy in Canada has evolved quite considerably. Since 2001, Canadian employees have a right to a 1 year paid parental leave; those in the province of Québec have a better paid, more flexible regime. This paper first shows that Québec is somewhat of an exception in the North American context, with its inclusive mode of governance which contributes to positive policies in terms of family and childcare. This is due to a few elements: the recognition of a declining birthrate, but more importantly the significant involvement and actions of women’s advocacy organizations, in the context of an inclusive governance of family policy. We will defend the hypothesis that Québec has adopted a cumulative (or work–family balance) model in the field of work–family relation, while the US and English Canada tend to still resort mainly to a laissez-faire attitude, which to this day has limited employee rights in terms of parental leave, but also in terms of child care.     

<Emphasis Type="BoldItalic">Mad Money</Emphasis> stock recommendations: market reaction and performance

We examine the stock recommendations of Jim Cramer televised on CNBC’s Mad Money, and document significant market reactions (i.e., announcement returns and volume) to Cramer’s recommendations, particularly for small capitalization stocks. The following findings indicate that the announcement returns are primarily due to price pressure from uninformed trading as opposed to the recommendations providing new value related information: announcement returns reverse following buy recommendations; bid-ask spreads temporarily decline; and there is no evidence of positive longer-term abnormal returns. One implication, when considered in combination with other works, is that investors should be cautious in following stock recommendations announced in the mass-media.     

Network motifs in an inter-firm network

Firms build business relationships during economic activities. The goal of this paper is to clarify production mechanisms and economic functions by identifying characteristic patterns of inter-firm interactions. In this paper, we empirically analyze an inter-firm network consisting of about one million firms and four million directed links, in order to specify network motifs, which are small subgraphs that occur more frequently than expected in a randomly generated network. We found that V-shaped triads are network motifs, while feedforward and feedback loop are anti-motifs. By defining roles in the subgraph according to structural equivalence, we also detected the significance profile of roles characterizing the industry sector. The taxonomy of industries obtained from the profiles is economically meaningful. These empirical findings may serve to provide an easily interpretable view of the entire inter-firm network and to improve the efficiency and safety of economic systems.     

Application of optimal control in man power planning

Many techniques are met in the literature (see for instance Bartholomew and Forbes (Statistical Techniques for Manpower Planning. wiley, New York 1979); Gunz (Organiz. Stud. 9(4), 529–554, 1988); Becker and Huselid (Human Resour. Manage. 38, 287–301, 1999); Wagner et al. (J. Manage. Med. 14(5/6), 383–405, 2000); Harris and Ogbonna (J. Business Res. 51, 157–166, 2001); Rogg et al. (J. Manage. 27, 431–449, 2001), among others), for planning the manpower resources. However, we haven’t seen in the literature an empirical study regarding the proper application of optimal control, which considered to be the most efficient method for multi-objective programming. With this in mind, we analyse in this paper the way of applying optimal control for manpower planning. For this purpose, and in order to facilitate the presentation, we first adopted a comparatively simple dynamic system (plant), with analytical presentation of stocks and flows. Next we proceed to the formulation of an optimal control problem, aiming to achieve in the most satisfactory way some preassigned targets. These targets mainly refer to a desirable trajectory of the plant stocks over time, in order to fully satisfy the needs for human resources over the planning horizon. Finally we present a method of solution of the formulated control problem which is based on the use of the generalized inverse Lazaridis (Qual. Quan. 120, 297–306, 1986). We believe that it is very important for successful management, that the policy makers have to know the effect of their polices and to determine the optimal path of the state variables (i.e. the ones describing the system) before the realization of the plan, so as to be able to reform their strategies, reallocate the resources and arrange the infrastructure accordingly, if all these are necessary, as it can be depicted from the optimal control solution.     

Academic content,research productivity,and tenure

This study examines the influence of a Finance doctoral program’s academic content on the research productivity of the graduates at the time of the tenure decision. The results of this investigation show that a Finance program’s academic content has no influence on the total number of publications of program graduates, but finds a significant relationship between academic content and graduate’s records of publications in top finance journals by the time of the tenure evaluation. More precisely, doctoral programs requiring more mathematically oriented classes such as Continuous Time Finance and/or Stochastic Calculus produce graduates who have a better record of publication in top finance journals at the time of tenure than those graduating from programs without these requirements.     

Generalization practices in qualitative research: a mixed methods case study

The purpose of this mixed methods case study was to examine the generalization practices in qualitative research published in a reputable qualitative journal. In order to accomplish this, all qualitative research articles published in Qualitative Report since its inception in 1990 (n =  273) were examined. A quantitative analysis of the all 125 empirical qualitative research articles revealed that a significant proportion (i.e., 29.6%) of studies involved generalizations beyond the underlying sample that were made inappropriately by the author(s). A qualitative analysis identified the types of over-generalizations that occurred, which included making general recommendations for future practice and providing general policy implications based only on a few cases. Thus, a significant proportion of articles published in Qualitative Report lack what we call interpretive consistency.     

Using ad hoc measures for response styles: a cautionary note

This research note addresses the challenge of how to optimally measure acquiescence response style (ARS) and extreme response style (ERS). This is of crucial importance in assessing results from studies that have tried to identify antecedents of response styles (such as age, education level, national culture). Using survey data from the Netherlands, a comparison is made between the traditional method and a more recently proposed method of measuring ARS and ERS (i.e., the convergent validity across both methods is assessed). The traditional method is based on an ad hoc set of related items. The alternative method uses a set of randomly sampled items to optimize heterogeneity and representativeness of the items. It is found that the traditional method may lead to response style measures that are suboptimal for estimating levels of ARS and ERS as well as relations of ARS and ERS with other variables (like hypothesized antecedents). Recommendations on how to measure response styles are provided.     

Testing the impact of predefined and self-defined end anchors on the linearity of the category rating scale

In this research the impact of two types of end anchors on the linearity of the category rating scale is studied. Two functional measurement experiments were carried out, each requiring a different kind of judgement, i.e., job satisfaction ratings and attractiveness ratings. One group of participants rated the stimuli using a category rating scale with fixed anchors, while another group was presented with a self-anchoring category rating scale. The results indicate that researchers can be confident in the ability of both category rating scales to provide linear data. This implies that the different end anchors do not impact on the linearity of the category rating scale.     

Daily diaries in time use surveys. A solution to overcome measurement problems in single-activity events with long characteristic rhythms

Daily diaries are a widely used measurement tool in studies on the use of social time. However, while their high level of accuracy is supported by a lot of research, scholars often voice doubts regarding the validity of the estimates obtained if the characteristic rhythm of the events in question is not completed within a 24-h period. This study attempts to explain why, although these statistics are not wrong, they need to be understood correctly before proceeding with research based on them. To overcome the problem we will propose a solution for new surveys where use of diaries of this type is scheduled. Although this solution is not without limitations, they are much less restrictive than those imposed by traditional daily diaries.
