Missing Variables in Theories of Strategic Human Resource Management: Time, Cause, and Individuals

Much progress has been made with regard to theory building and application in the field of Strategic Human Resource Management (HRM) since Wright and McMahan’s (1992) critical review. While researchers have increasingly investigated the impact of HR on economic success within the Resource Based view of the firm, and have developed more middle level theories regarding the processes through which HR impacts firm performance, much work still needs to be done. This paper examines how future theorizing in SHRM should explore the concepts of time, cause, and individuals. Such consideration will drive more longitudinal research, more complex causal models, and consideration of multi-level phenomena

Scaling and data collapse from local moments in frustrated disordered quantum spin systems

Recently measurements on various spin-1/2 quantum magnets such as H$_3$LiIr$_2$O$_6$, LiZn$_2$Mo$_3$O$_8$, ZnCu$_3$(OH)$_6$Cl$_2$ and 1T-TaS$_2$ -- all described by magnetic frustration and quenched disorder but with no other common relation -- nevertheless showed apparently universal scaling features at low temperature. In particular the heat capacity C[H,T] in temperature T and magnetic field H exhibits T/H data collapse reminiscent of scaling near a critical point. Here we propose a theory for this scaling collapse based on an emergent random-singlet regime extended to include spin-orbit coupling and antisymmetric Dzyaloshinskii-Moriya (DM) interactions. We derive the scaling $C[H,T]/T \sim H^{-\gamma} F_q[T/H]$ with $F_q[x] = x^{q}$ at small $x$, with $q \in$ (0,1,2) an integer exponent whose value depends on spatial symmetries. The agreement with experiments indicates that a fraction of spins form random valence bonds and that these are surrounded by a quantum paramagnetic phase. We also discuss distinct scaling for magnetization with a $q$-dependent subdominant term enforced by Maxwell's relations.Comment: v2. Expanded argument in Appendix 2 and revised for clarity. v3.

Students’ Perception of the Quality of Learner Support Services in National Open University of Nigeria

Learner support is an important benchmark of open and distance learning because of the character of the learners and the temporal separation of the learner and the teacher. But the level of importance attached to these services and the level of satisfaction may vary according to gender. Thus this study examines the perception of students on the quality of learner support services in Port Harcourt study centre of NOUN. Two research questions and two hypotheses were posed and tested. The methodology adopted is a descriptive survey method, the instrument for data collection was questionnaire and the statistical tools used were mean, standard deviation and t test. The result of the test of hypotheses indicates that there were no significant differences in the level of importance and level of satisfaction between male and female learners. However, the study indicates that male learners attached less importance to learner support services and are less satisfied with the quality of the services. Our conclusion is that given the high mean score of the level of importance and the low mean score for the level of satisfaction the quality of learner support is not as high as the students would expect. This therefor calls for an improvement in the quality of learner support services to sustain learners’ commitment and continuity in the programme in NOUN.

Student Attainment and the Milwaukee Parental Choice Program

In this report we examine high school completion and postsecondary enrollment (a.k.a. “educational attainment”) of the cohort of 9th grade students who were in the Milwaukee Parental Choice Program (MPCP) at the beginning of our state-mandated evaluation of the MPCP in 2006. After tracking the MPCP 9th graders following the 2006-07 year and comparing them to a carefully matched sample of 9th graders who were in Milwaukee Public Schools (MPS) during the 2006-07 year, we use a combination of parent surveys and administrative (school) records to estimate attainment

School and Sector Switching in Milwaukee

In this report we analyze the movement of students to and from the Milwaukee Parental Choice Program (MPCP) and Milwaukee Public Schools (MPS). We also analyze student mobility between schools within each sector. The analysis rests on two separate sets of data: the administrative records we have collected as part of our separate analysis of academic achievement in MPCP (Witte , Wolf, Cowen, Fleming, & Lucas-McLean, 2010), and the results of an extensive set of surveys collected from parents of private and public school students

Characterization and expression analysis of Staphylococcus aureus pathogenicity island 3 - Implications for the evolution of staphylococcal pathogenicity islands

We describe the complete sequence of the 15.9-kb staphylococcal pathogenicity island 3 encoding staphylococcal enterotoxin serotypes B, K, and Q. The island, which meets the generally accepted definition of pathogenicity islands, contains 24 open reading frames potentially encoding proteins of more than 50 amino acids, including an apparently functional integrase. The element is bordered by two 17-bp direct repeats identical to those found flanking staphylococcal pathogenicity island 1. The island has extensive regions of homology to previously described pathogenicity islands, particularly staphylococcal pathogenicity islands 1 and bov. The expression of 22 of the 24 open reading frames contained on staphylococcal pathogenicity island 3 was detected either in vitro during growth in a laboratory medium or serum or in vivo in a rabbit model of toxic shock syndrome using DNA microarrays. The effect of oxygen tension on staphylococcal pathogenicity island 3 gene expression was also examined. By comparison with the known staphylococcal pathogenicity islands in the context of gene expression described here, we propose a model of pathogenicity island origin and evolution involving specialized transduction events and addition, deletion, or recombination of pathogenicity island "modules.

Measurement Error in Research on Human Resources and Firm Performance: Additional Data and Suggestions for Future Research

Gerhart and colleagues and Huselid and Becker recently debated the presence and implications of measurement error in measures of human resource practices. This paper presents data from three more studies, one of large organizations from different industries at the corporate level, one from commercial banks, and the other of autonomous business units at the level of the job. Results of all three studies provide additional evidence that single respondent measures of HR practices contain large amounts of measurement error. Implications for future research are discussed

On the Kauffman Bracket Skein Module of the Quaternionic Manifold

We use recoupling theory to study the Kauffman bracket skein module of the quaternionic manifold over Z[A(+/- 1)] localized by inverting all the cyclotomic polynomials. We prove that the skein module is spanned by five elements. Using the quantum invariants of these skein elements and the Z(2)-homology of the manifold, we determine that they are linearly independent

The Secret Sharers: Anthony Rivers and the Appellant Controversy, 1601-2

Historians have known of the letters of “Anthony Rivers,” recounting religious, political, and military affairs from the court in London in 1601–3, and of certain dispatches from Rome forwarded to Robert Cecil by Thomas Phelippes, “the Decipherer,” in 1602. In this article, Patrick Martin and John Finnis show that the letters and dispatches were integral to a coordinated effort by William Sterrell, secretary to the Earl of Worcester and long-time double agent, and Father Robert Persons, prefect in Rome of the Jesuit mission to England, to frustrate the climactic third appeal to the pope by the disaffected secular priests known as the Appellants. Sterell assisted Persons by authoring the “Rivers” letters, which kept Persons and others informed of the government\u27s actions and policies, as well as by promptly forwarding to him for refutation the Appellants\u27 publications as they appeared, and notably by forwarding to the queen and Cecil the dispatches from Rome—which we show were written by Persons himself. This coordinated effort had some success
