This paper’s purpose is to test the employability paradox by adopting a combined linear and non-linear approach based on the conservation of resource (COR) theory and the prospect theory and further to discuss it in two groups of employees with different seniority following the career timetable perspective. A total of 623 pairs of matched employee and manager surveys was collected from 27 Chinese enterprises in two waves. Hierarchical regression analysis was used to test the hypotheses. The results show no paradox that perceived employability promotes both an employee’s turnover intention and performance. Specifically, perceived employability has a significant inverted U-shaped effect on turnover intention but no direct influence on job performance. Seniority is a moderator, showing the curvilinear relationship only exhibits for employees with shorter work seniority (≤3 years), and a positive linear relationship between perceived employability and job performance only exists for employees with longer seniority (>3 years). This study emphasizes the value of employability for employers and proposes who is more suitable and what timetable should be followed for employability enhancement in practice. In addition, the study provides an enlightening finding of the inverted U-shaped relationship between perceived employability and turnover intention, applies the COR theory and the prospect theory to explain the non-linear relationship, validates the effect of too much of a good thing (TMGT), and negates the paradox from the perspective of the perceived general employability and career timetable.

Research background and hypothesis. While for some authors team sport players should have a high VO 2 max, we hypothesize that there exist a non-linear relationship between VO 2 max and basketball performance. Research aims. Research aims were to study the correlation between basketball performance and VO 2 max in young elite basketball players and the effects of VO 2 max training on performance.Research methods. In the fi rst study, 67 high-level young basketball players performed a shuttle-run test (SRT) to measure their VO 2 max. Competition performance assessed through statistics ratings of 5 matches was determined for all players. The correlation between VO 2 max and performance was calculated. In the second study, the VO 2 max and the competition performance of 34 high-level young male players was assessed as in the fi rst study. The sample was divided into control and experimental groups, which trained their VO 2 max. At the end of the training period all participants repeated the SRT. The results of 4 games played before the fi rst test and 4 games played after the second test (against the same opponents) were compared in both groups.Research results. In the fi rst study we found a correlation of VO 2 max with steals in both groups. In the second study, the experimental group increased their VO 2 max and steals per game, but they decreased free throw per game and free throw percentage. Discussion and conclusions. No correlation was found between VO 2 max and competitive performance in this study, and increased VO 2 max had no effect on most of the studied variables. The data therefore suggest a non-linear relationship between VO 2 max and basketball performance.Keywords: aerobic capacity, basketball performance, non-linear relationship.

We investigate the relationship between operating performance and ownership structure using a sample of Italian IPO-firms in the period 1995-1999. Overall, we find that their performance declines after the IPO. We find evidence of a non-linear relationship between ownership and performance using different measures of operating performance and managerial ownership. This result supports the hypothesis of a combined effect of ownership on firm performance, with a positive effect at low and high levels of managerial ownership (alignment of interest hypothesis) and a negative effect at intermediate levels (entrenchment hypothesis)

Summary: In the United States' normative population for the WAIS-R, differences (Ds) between persons' verbal and performance IQs (VIQs and PIQs) tend to increase with an increase in full scale IQs (FSIQs). This suggests that norm-referenced interpretations of Ds should take FSIQs into account. Two new graphs are presented to facilitate this type of interpretation. One of these graphs estimates the mean of absolute values of D (called typical D) at each FSIQ level of the US normative population. The other graph estimates the absolute value of D that is exceeded only 5% of the time (called abnormal D) at each FSIQ level of this population. A graph for the identification of conventional “statistically significant Ds” (also called “reliable Ds”) is also presented. A reliable D is defined in the context of classical true score theory as an absolute D that is unlikely (p < .05) to be exceeded by a person whose true VIQ and PIQ are equal. As conventionally defined reliable Ds do not depend on the FSIQ. The graphs of typical and abnormal Ds are based on quadratic models of the relation of sizes of Ds to FSIQs. These models are generalizations of models described in Hsu (1996) . The new graphical method of identifying Abnormal Ds is compared to the conventional Payne-Jones method of identifying these Ds. Implications of the three juxtaposed graphs for the interpretation of VIQ-PIQ differences are discussed.

Penelitian ini bertujuan untuk : 1) Mengetahui gambaran pemasaran sawi manis di Kecamatan Jambi Selatan, 2) Menghitung efisiensi pemasaran sawi manis dilihat dari analisis market structure, market conduct, dan market performance (SCP). Data dianalisis secara deskriptif kuantitatif dan kualitatif dengan pendekatan structure, conduct, and performance of market (SCP). Berdasarkan penelitian, pemasaran sawi manis di Kecamatan Jambi Selatan terdiri dari lima pola saluran pemasaran, yaitu : 1) petani-konsumen ; 2) petani-pedagang pengumpul besar (PPB)-agen/pedagang pengecer-konsumen ; 3) petani-pedagang pengecer-konsumen; 4) petani-pedagang pengumpul kecil (PPK)-pedagang pengecer-konsumen; 5) petani-pasar modern-konsumen. Fungsi pemasaran yang dilakukan oleh lembaga-lembaga pemasaran, yaitu fungsi pertukaran, fungsi fisik, dan fungsi fasilitas. Dengan pendekatan market structure, pasar sawi manis di Jambi Selatan cenderung mengarah kepada persaingan oligopoli murni. Dilihat dari perilaku pasar, sistem pembayaran kemudian masih terjadi antara pedagang pengumpul dengan petani dan antara pedagang pengumpul dengan pedagang eceran. Sedangkan kinerja pasar menunjukkan bahwa penyebaran marjin, farmer’s share, dan rasio keuntungan tidak merata pada masing-masing lembaga pemasaran. Dari indikator SCP yang telah dijelaskan  di atas dapat diketahui bahwa pemasaran sawi manis di Jambi Selatan belum efisien. Berdasarkan kondisi saat ini dan hasil analisis yang telah dilakukan, saluran pemasaran IV (petani-pedagang pengumpul kecil (PPK)-pedagang pengecer-konsumen) merupakan alternatif saluran pemasaran yang efisien yang dapat dipilih oleh petani.   Kata Kunci : efisiensi, pemasaran, sawi manis, SCP (structure, conduct, and performance of market)

Abstract In this paper, we design the simultaneous wireless information and power transfer (SWIPT) protocol for massive multi-input multi-output (mMIMO) system with non-linear energy-harvesting (EH) terminals. In this system, the base station (BS) serves a set of uplink fixed half-duplex (HD) terminals with non-linear energy harvester. Considering the non-linearity of practical energy-harvesting circuits, we adopt the realistic non-linear EH model rather than the idealistic linear EH model. The proposed SWIPT protocol can be divided into two phases. The first phase is designed for terminals EH and downlink training. A beam domain energy beamforming method is employed for the wireless power transmission. In the second phase, the BS forms the two-layer receive beamformers for the reception of signals transmitted by terminals. In order to improve the spectral efficiency (SE) of the system, the BS transmit power- and time-switching ratios are optimized. Simulation results show the superiority of the proposed beam-domain SWIPT protocol on SE performance compared with the conventional mMIMO SWIPT protocols.

As it is appreciated that learning is a non-linear process – implying that coaching methodologies in sport should be accommodative – it is reasonable to suggest that player development pathways should also account for this non-linearity. A constraints-led approach (CLA), predicated on the theory of ecological dynamics, has been suggested as a viable framework for capturing the non-linearity of learning, development and performance in sport. The CLA articulates how skills emerge through the interaction of different constraints (task-environment-performer). However, despite its well-established theoretical roots, there are challenges to implementing it in practice. Accordingly, to help practitioners navigate such challenges, this paper proposes a user-friendly framework that demonstrates the benefits of a CLA. Specifically, to conceptualize the non-linear and individualized nature of learning, and how it can inform player development, we apply Adolph’s notion of learning IN development to explain the fundamental ideas of a CLA. We then exemplify a learning IN development framework, based on a CLA, brought to life in a high-level youth football organization. We contend that this framework can provide a novel approach for presenting the key ideas of a CLA and its powerful pedagogic concepts to practitioners at all levels, informing coach education programs, player development frameworks and learning environment designs in sport.
